Wittenstein ABSTRACT: A deck of tabulating cards having names and addresses printed thereon in legible form is used as a master mailing list. The cards are passed through a photocopying machine which, in addition to the usual document copying facilities, has equipment for tabulating card handling. The cards are copied automatically in rapid sequence and in overlapping relationship, so that a series of names and addresses is printed on a continuous strip of copy paper with a minimum of blank space between. Various aspects of the operation of a conventional photocopying machine are altered to achieve a continuous card copying cycle. A continuous output strip emerges from the photocopying machine, and is subsequently processed by conventional labeling machinery which severs the strip into individual address labels and glues these to respective pieces of mail.

RASTORGUYEFF ATTORNEY LABEL-MAKING SYSTEM FIELD OF THE INVENTION The invention relates generally to the field of high-speed automatic labelling, and particularly concerns the photocopying of tabulating cards to produce mailing lists and labels.
THE PRIOR ART At the present time, the best known technique for rapid and automatic mail addressing is subject to a number ofsevere disadvantages. This technique involves the use ofa printing press to make a series of labels, each one including the name and address of one of the intended recipients. The printing presses which are used for this purpose require a set of individual address plates on which the printed material is represented by raised characters. Such plates have to be made of relatively heavy guage metallic material in order to withstand the printing impressions to which they are subjected. Consequently, a full set of printing plates, each one representing one address in a high volume mailing, is both heavy and bulky, the raised characters contributing substantially to the bulk.
Another disadvantage of these plates is that they are fairly expensive to produce. Therefore economic considerations normally dictate that they be stored after use. But storage can be a considerable problem, in view of the bulk and weight involved. In addition, the plates are somewhat vulnerable to bending and to damage which may be inflicted on the raised characters. Therefore transportation to a storage location must be done with a fair amount of care, this adding to the burden.
Still another disadvantage of such plates is that the printing ink which adheres to them must be washed offaftcr each use.
Finally, the mechanism by which such plates are passed through the printing press is complex, yet must withstand the loads imposed thereon by the weight of the plates. Therefore the mechanism is subject to breakdown, and also is too noisy for ordinary office use.
SUMMARY AND OBJECTS OF THE INVENTION The present invention avoids all these problems, but without sacrificing the advantages of rapid and automatic operation. The solution is to take the name and address information from a deck of flat, light weight record cards ofa flexible material; for example conventional tabulating cards. The advantages of this approach are numerous. The tabulating cards have utility for other than printing purposes. In most cases, a deck of tabulating cards with legible name and address information printed thereon, and with the same and other information also recorded thereon in punch code, is already maintained for various business purposes. This deck now takes on the additional function of acting occasionally as a set of printing masters for mailing labels. Thus, no additional storage space is required. Secondly, tabulating cards are flat instead of three-dimensional, and they are light and flexible. Therefore they take up less room than printing plates, they are easier to handle, they are less vulnerable, they are inexpensively replaced when damaged or outdated, and the apparatus required for handling such cards is not as complex and not subject to the same operating loads as a printing press. Furthermore, a deck of tabulating cards is normally maintained in alphabetical or some other logical order, and the order can be changed or cards selected out as required by means of conventional tabulating equipment. Such flexibility and ease ofhandling are not available with printing plates.
Accordingly, the objective of this invention may be broadly stated as the provision of new equipment to be used for high volume mail addressing and the like. In more specific terms, the objects of the invention are to avoid printing plates and presses, with all the weight, bulk vulnerability, expense, mess, noise. breakdowns, inconvenience and problems of transportation and storage which they entail; and to use instead tabulating cards which have utility apart from mail labeling, which are light, flat, flexible, inexpensive to prepare and replace, clean, quiet, convenient to use and revise, and which pose no particular transportation or storage problems.
It is also an object to copy these tabulating cards by means of a photocopying machine which is quiet enough for an ordinary office, trouble-free, useable by general-purpose clerical personnel, and has all the conventional document copying capabilities of such machines. Another object is to modify an existing photocopying machine so as to provide additional card copying and label making capabilites with minimal engineering changes and at a minimal additional cost. Another object is to provide two entirely different operating modes; i.e. single documents and continuous card copying.
One form of the invention employs a plurality of record cards formed of flexible sheet material, each card having an address recorded thereon. The address may be recorded either in legible form suitable for photocopying, or in magnetic ink, punch code, or some other form readable by data processing equipment. Then a photocopying machine, or suitable data processing equipment which reads magnetic ink, punch code or the like and which has a printout capability, reads the record cards sequentially, scans each address in turn, and prints the addresses sequentially. Another part of the mechanism feeds sheet material for successive labels sequentially through the printing means; the printed addresses being thereafter applied to respective pieces of mail.
In the preferred form of the invention, the copying machine employed is a dual purpose device which can operate either in the conventional document copying mode or for rapid sequential copying ofa deck of data cards. In the document mode the output of such a machine consists of discrete photocopies, and in the card mode it is preferably a continuous strip of copy paper with successive mailing label information distributed along the length thereof. This continuous strip is reeled up as it emerges from the photocopying machine, and later put into a conventional labeling machine of the type originally designed to accept the same type of continuous strip output from address label printing presses. The labeling machinery operates by severing the strip into discrete labels and gluing these sequentially to respective pieces of mail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the overall construction of aphotocopying machine 20 which is designed for the performance of two alternative functions, as the need may appear. On the one hand it is capable of rapid automatic sequential copying of tabulating cards in order to prepare a continuous strip of mailing address labels, and on the other hand it is operable for conventional single document copying.
In general terms, the document capability resides in conventional copying mechanism including a copyingstation 22 at which a document is passed over a transparent plate 24 to be scanned by the beam 26 of a copyinglamp 28. The light is reflected back from the document as abeam 30 toward amirror 32 which redirects the light as abeam 34. The latter is focused by a lens 36 upon a strip of copying paper 40 within aprinting station 38.
When the machine is operated in the document mode, one document at a time is manually inserted into afeed channel 46 formed between upper andlower plates 48 and 50 anddeflector plate 254. Manual insertion causes the document to be fed around the bend ofthechannel 46 byrollers 51 and 53, (FIG. 12) until it is gripped between a pair of motor drivenfeed rollers 52 and 54, which then convey the document through the copyingstation 22. Subsequently another pair of motor drivenfeed rollers 56 and 58 convey the document out ofthe copying station.
A special receiving tray 60 (shown detached from the machine 20) is assembled therewith when the machine is to be used in the document mode. Such assembly is accomplished by placing thedocument tray 60 over a slopingsurface 62 at the front of the machine. In this position a rear flange 64 hooks over the rear edge 66 of the slopedmember 62 to secure the tray in place. The flange 64 also abuts eccentrically against a pair of gatingmembers 70, rotating the gates downwardly about theirshaft 72 to the dotted line position of FIG. 1. When so positioned, the gating members divert the original document upwardly as it emerges from between thefeed rollers 56 and 58, so that it is deposited in thedocument tray 60. A restraininglip 74 at the front of thedocument tray 60 retains the original document therein.
When operating in the document mode, themachine 20 automatically cuts the copies to the length of the original documents. Copy paper 40 is taken, by means of a pair offeed rollers 76 and 78, from a supply roller 42 wound upon a spool 44, which is rotatably mounted upon ashaft 47. Therollers 76 and 78 are motor driven by means of a conventional clutch (not shown) which is engaged during the time it takes for the original document to pass a length sensing switch SW-4 adjacent thechannel 46. Fromrollers 76 and 78, the copy paper passes through a cutoff knife mechanism 80 to another pair of motor drivenfeed rollers 82 and 84. After a length of copy paper equal to the length of the original document has been fed past the cutoff knife mechanism 80, another switch SW-3 located adjacent thechannel 46 senses the trailing edge of the document and energizes a circuit to actuate the knife mechanism 80, thus cutting the copy paper to the proper length.
Thephotocopier 20 could be any known type, but is preferably an electrostatic machine of the kind which has become common in recent years. As such, it includes anelectrostatic charging mechanism 86 through which the copy paper is fed by therollers 82 and 84. Upon emerging from the charging mechanism and passing through theimage station 38, the copy paper is gripped by another pair of motor driven feed rollers 92 and 94, and fed into a conventional toner solution contained within areservoir 96. Upon emerging from the toner reservoir it is fed by another pair of motor drivenrollers 98 and 100 to a dryingstationv 102. The copy paper is conveyed through the drying station and toward anexit 104 by means ofbelts 106 and 108 and therotating rollers 110, 112 and 114. The finished copy may then be manually removed fromexit 104.
The mechanism thus generally described is conventionally housed in a cabinet comprising arear panel 21, top panel 23,floor panel 25, andfront panel 436. The cabinet stands above table-top level onfeet 27, and has within it variousinternal partitions 29.
In accordance with this invention, when themachine 20 is operated in the card copying mode, thedocument tray 60 is detached, allowing thegating members 70 to return under spring bias to their raised positions, illustrated by the solid lines of FIG. 1. The material to be copied is a conventional deck of tabulating cards 116 fed from ahopper 120 mounted atop themachine 20. Motor drivenrollers 122 and 124 cooperate to feed successive cards into a throat formed by theplate 50 and thedeflector plate 254 immediately in front of therollers 52 and 54. The latter rollers then pass each card in succession through the copyingstation 22, from which they are withdrawn by therollers 56 and 58. Thus, as an example of the way in which the card copying operation takes advantage of the existing photocopying mechanism, the cards are ultimately conveyed through the copying station by the same feed mechanism as are the documents when the machine is in the other operating mode.
The upper position of thegate member 70 causes each of the cards emerging from the copying station to be diverted downwardly through apassageway 379 into anoutput bin 126, where they are collected upon a vertically movablecard catcher tray 128. During operation thetray 128 sinks lower to accommodate the increasing accumulation of tabulating cards thereon.
In the card copying mode the cutoff knife mechanism 80 is disabled, and a narrow strip of copy paper 41 (narrower than the document size copy paper 40) is unreeled in a continuous strip from a supply roll 43 which is wound on a spool 45 rotatably supported on theshaft 47. Thenarrow strip 41 traverses the same path described above for the wider strip 40, up to the point where they both emerge from the cabinet atexit 104. Beyond that point, the narrow output strip 41 (which has not been severed into discrete copies as is the wide strip 40) passes around a motor drivenfeed roller 130 and is wound upon atakeup reel 132, to form anoutput roll 134. Thetakeup reel 132 is driven by ashaft 136 which in turn is rotated by a pair oflargecircular rims 138 in frictional driving engagement with the motor drivenroller 130.
A representative segment of thecontinuous output strip 41, as it looks when torn from theroll 134, is shown in FIG. 2. There it is seen that the cardcopying output strip 41 has successive name and address blocks 138 distributed along the length thereof, each one defining alabel 142. Such anoutput roll 134 may then be used as the input to a conventional mail labeling machine of the kind now commercially available. (Such machines were originally designed to take a similar output strip from a conventional address label printing press.) The labeling machinery severs theindividual labels 142 from each other along the dashedlines 139, applies a suitable adhesive material to the back of each label, and presses the glued labels into adhesive relationship with respective pieces ofmail 144 (see FIG. 3).
FIGS. 4 through 7 provide a more detailed view of the tabulatingcard supply hopper 120 and the mechanism for delivering a continuous stream of cards from that hopper to the copyingstation 22. The machine has a main drive motor, not shown, which is connected to drive all thefeed rollers 56 and 58, 52 and 54, 122 and 124, 76 and 78, 82 and 64, 88 and 90, 92 and 94, 98 and 100, and theconveyor belt roller 110, either directly or indirectly from acommon drive chain 150. This type of drive is presently conventional in electrostatic photocopying machines of the kind modified for the purposes of this invention. For driving thefeed rollers 122 and 124, which insert the tabulating cards 116 into the nip ofrollers 52 and 54, thechain 150 engages asprocket wheel 152 affixed toshaft 154 which is journaled in avertical panel 157 of themachine 20 by means of abushing 159. Theshaft 154 drives agear 186 secured thereto, which in turn drives agear 182 which rotates on ashaft 183 protruding from alug 184 formed in onesidewall 178 ofhopper 120.Gear 102 in turn drives agear 176 secured to alower roller shaft 174, which is journaled in both hopper sidewalls 178 and has two lowercard feed rollers 124 secured thereto.Shaft 174 also has agear wheel 168 secured thereto for driving agear 169 secured to anupper roller shaft 171 which has two uppercard feed rollers 122 secured thereto. Eachupper roller 122 is paired with one of thelower rollers 124 for gripping and feeding successive tabulating cards 116.
In order to deliver successive tabulating cards 116 to thefeed rollers 122 and 124, there is employed a pair ofcard pickers 156 of the kind which is common in card handling machinery. As best seen in FIGS. 14 and 15, eachcard picker 156 has a card-engagingmember 158 which protrudes slightly less than the thickness of a tabulating card above the top surface of the picker so as to engage a single tabulating card 116, Le. the bottom one in thehopper 120. In order to reach the bottom card, thepickers 156 ride inaccess slots 160 which are formed in thefloor 162 of thecard supply hopper 120. Thepickers 156 ar reciprocated longitudinally within these slots, as indicated byarrows 162, FIG. 5, by means ofacarrier shaft 166 164 engaging the opposite ends ofacarrier shaft 164. On each forward stroke of the pickers 156 (i.e. in the downward direction as viewed in FIG. 4) themembers 158 catch a tabulating card 116 and deliver it to thefeed rollers 122 and 124. On each return stroke (upward in FIG. 4) the pickers return to their initial position so that themembers 158 can engage the next tabulating card 116 and repeat the operation.
The drive links 166 are made to perform their reciprocating motion by means of respective crank wheels, thegear wheel 168 and anotherwheel 170, to which they are cccentrically connected bypins 172. The crankwheels 168 and 170 are secured to opposite ends of thelower roller shaft 174 Thus the drive toshaft 174 not only is imparted torollers 124, and viagear 169 torollers 122, but also serves to reciprocate thelinks 166 and thecard pickers 156. The motion of thecard pickers 156 is guided in a linear direction notwithstanding the cranking of thelinks 166, by pairs ofside rails 180 which are secured to the lower surface of thehopper floor 162 and which extend laterally into sliding engagement withslots 181 formed in thecard pickers 156.
In order to interrupt the delivery of cards 116 by stopping thecard feed rollers 122 and 124 and thecard pickers 156, there is provided a clutch mechanism 190 (FIGS. 6 and 7) controlled by a solenoid SOL-4 secured to abracket 192 mounted upon one of thehopper side panels 178. Thegear 176 is continuously driven, but is not continuously connected to theshaft 174. Instead, thegear 176 is secured to acylindrical drive hub 194 which is rotatable relative to theshaft 174. Thedrive hub 194 in turn may be drivingly engaged with or disengaged from a drivenhub 196 on theshaft 174 which is continuously connected to that shaft by means ofapin 198. In order to accomplish the engaging and disengaging function, the clutch 190 comprises acoil spring 200 which surrounds bothhubs 194 and 196, and is normally wound sufficiently tightly thereon so that the coil spring clasps them both and drivingly connects the two hubs together. Under these conditions, the continuously drivengear 176 and itshub 194 transmit power via the clutchingspringl hub 196 and P 193 t0 thelower shaft 174. The shaft then drives thelower rollers 124 and the wheels and 168, which actuate thelinks 166 to drive thecard pickers 156, andwheel 168 also drives thegear 169 to rotate theupper shaft 171 androllers 122.
One of therollers 124, seen at the right in FIG. 5 is affixed directly to theshaft 174, while the other, as seen in FIGS. 6 and 7, is mounted upon the drivenhub 196 and drivingly secured thereto by means of afastener 202. The fastener secures an eccentric arm 204 of thehub 196 to the central disc of theroller 124, and also anchors theadjacent end 206 to the clutchingspring 200.
In order to disengage the clutch 190, thefree end 208 of thespring 200 is engaged by a blockingmember 210 which is mounted upon ashaft 212 journaled within abushing 214 secured to thehopper side panel 178. The driving direction of the mechanism is clockwise, as indicated byarrow 216 in FIG. 7. When the drivinghub 194 attempts to rotate the clutchingspring 200 in that direction, the blockingmember 210 engages thespring end 208 and blocks rotation of the clutchingspring 200. To the extent that the clutchingspring 200 can be rotated by thedrive hub 194, it only serves to turn thespring 200 in the uncoiling direction relative to the blockedend 208, thus releasing the clutching engagement of thespring 200.
When it is necessary to release thespring end 208 and engage the clutch 190, the blockingmember 210 is moved to the left relative to the view of FIG. 7 to remove it from blocking relationship with thespring end 208. This is accomplished by rotating the blockingmember shaft 212 clockwise by means of acontrol link 218 secured thereto. The control link in turn is pivotally connected by means ofa pin 220 to a connectinglink 222 which functions by pulling upwardly upon the pivot pin 220 to produce clockwise rotation of thelink 218. The connecting link in turn is actuated by thearmature 224 of solenoid SOL-4, to which it is connected by means of apivot pin 226.
So long as the solenoid SOL-4 is energized, itsarmature 224 is attracted upwardly to lift the connectinglink 222 and rotate control link 218 andshaft 212 clockwise, thereby preventing the blockingelement 210 from interfering withspring end 208. Under these circumstances the clockwise torque exerted on clutchingspring 200 by thedrive hub 194 tends to tighten the spring against thehubs 194 and 196 for a driving connection therebetween. The clutch is then en gaged, to complete the drive train to thecard pickers 156 and thefeed rollers 122 and 124.
When the solenoid SOL-4 is deenergized, itsarmature 224 is lowered under spring bias, driving connectinglink 222 down to rotate control link 218 andshaft 212 counterclockwise. This returns blockingelement 210 to the position in which it interferes with thespring end 208. Then, as soon as the clutchingspring 200 completes its current revolution and comes into position for thespring end 208 to reengage the blockingelement 210, the clutch 190 is disengaged.
In order to bring thefeed rollers 122 and 124 and thecard pickers 156 to an immediate halt and insure that the pickers do not stop at an indefinite position after disengagement of the clutch 190, there is provided astop member 230 secured by means of apivot pin 232 to the underside of thehopper floor 162. This stop member is normally rotated clockwise about its pivot pin, as seen in the view of FIG. 6, by means of abiasing spring 234. One end of the spring is hooked through anaperture 236 at one end ofthestop member 230, and the other end of the spring is hooked around apin 238 protruding downwardly from the lower surface of thehopper floor 162. When in its biased position, thestop 230 interposes its free end in the path of rotation of a cooperatingstop element 240 which is secured to the central web of thenearby roller 124 by means ofafastener 242. Theroller 124 rotates clockwise relative to FIG. 7 until theelement 240 strikes themember 230 to provide a positive stop. This halts one of therollers 124 and, because oftheir mutual connection toshaft 174, also stops theother roller 124, theupper rollers 122, and thecard pickers 156. This causes the entire card feed mechanism to stop in a known position, and also cuts off the card feed abruptly and precisely.
In the blocking position ofstop 230. its biased rotation about thepivot pin 232 is limited by the blockingmember 210 to prevent themember 230 from rotatingpast element 240. When the solenoid SOL-4 engages the clutch 190, the motion of blockingelement 210 to the left relative to FIGS. 6 and 7 rotates stop 230 counterclockwise against the urging of its biasingspring 234, so as to remove the stop from blocking engagement withelement 240, thereby releasingcard pickers 156 and thefeed rollers 122 and 124 for a resumption of card feed. When the solenoid SOL-4 is later deenergized to disengage clutch 190, the return of blockingelement 210 to its initial position allows thestop 230 to return under spring bias to its operative position. Then at the conclusion of the current revolution of thenearby roller 124,element 240 once again engages thestop 230.
When the clutch 190 is engaged, thepickers 156 slide each successive tabulating card 116 across thehopper floor 162 and through anexit space 250 between the hopper floor and the lower end of a hopperrear wall 252. The size of theexit space 250 is adjustable, by means ofelements 251 and 253, (FIG. 14) to admit no more than one tabulating card 116 for each picker cycle. Theelement 251 is adjustable forwardly and rearwardly within a channel 255 (FIG. formed in thehopper floor 162, and cooperates with theelement 253 which is adjustable up and down in a channel 257 (FIG. 14) formed in thehopper wall 252.
Each tabulating card 116 as it emerges from theexit space 250 is gripped between the pairs ofcard feed rollers 122 and 124, and thereby fed across aplate 254 which guides the cards into thegrip offeed rollers 52 and 54, which deliver all material to be copied, documents and tabulating cards alike, to the copyingstation 22.
FIGS. 4 and 5 show theguide plate 254 is formed with a first pair oflugs 256 at opposite sides thereof which are secured to respectivehopper side panels 178 by means ofpins 258, which permit the guide plate to pivot relative to thecard hopper 120. In addition, the guide plate is provided with two further dependinglugs 260 at opposite sides thereof which are pivotally connected by means ofpins 262 to the copyingmachine sidewalls 157. Finally, the hopper sidewalls 178 are also provided with dependinglugs 264 andbushings 265 by means of which theentire card hopper 120 is pivotally mounted upon ashaft 266, which in turn is supported bybushings 268 upon the copyingmachine sidewalls 157.
The hoppers downward movement is limited by a pair of dependinglugs 270, one of which is visible in FIG. 4, which strike against ashaft 272 supported between the copyingmachine side panels 157.Shaft 272 is so positioned that thehopper floor 162 is inclined to the right as seen in FIGS. 4 and 7 to facilitate the exit of tabulating cards 116 through thespace 250. The front of thehopper 120 has a pair of short posts 274 (FIGS. 1 and 4) which serve only to align the lower tabulating cards in the deck 116, and are not required to retain the upper cards within thehopper 120.
Below thehopper floor 162 is a switch SW-7 (FIGS. 1 and 5) having afeeler arm 230 which protrudes up through anaperture 282 in thehopper floor 162 in order to sense the tabulating card deck 116. As long as cards are present to depress the switch plunger 280, the electrical control circuit (FIG. 16) is advised that the tabulating cards are available in the hopper to be copied. A heavy metal card follower weight 117 (FIG. 1) keeps the cards flat for engagement with thepickers 156, and for actuation of the switch SW-7 even when only one card remains in the hopper.Weight 117 however has the usual relief (not shown) to prevent it along from actuating the switch when the cards are exhausted. Under those circumstances cards no longer depress the switch plunger 280 and the control circuit is advised that the card copying operation has been completed. The switch SW-7 also appears schematically in the electrical circuit of FIG. 16, where it is revealed as one of the elements controlling the circuit for energizing a solenoid SOL2 which operates the copy paper cutoff knife mechanism 80. As is described more fully below, one of the conditions for severing the copy paper strip 40 is completion of the tabulating card deck 116; hence the connection of the card sensing switch SW-7 to the cutoff knife solenoid SOL-2.
Now that the mechanism for supplying successive tabulating cards 116 to the copyingstation 22 has been described, we turn our attention to FIGS. 12 and 13 for a description of the copy paper feed control, so that the dual capability of themachine 20 may be more fully understood. There it is seen that the document sensing switches SW-3 and SW-4 are suspended from atop panel 290 by means of an inverted U- shapedbracket 292. These switches haverespective feeler arms 294 and 296 which extend downwardly into thedocument channel 46. In the document mode,feeler arm 296 closes switch SW-4 to energize a solenoid SOL-1 (FIG. 16) over the entire length of the document inserted intochannel 46. Solenoid SOL-1 then engages a conventional clutch (not shown) for driving the copypaper feed rollers 76 and 78 during the time that it takes the original document to pass thefeller 296. As a result, the feed rollers are made to unreel a length of copy paper 40 equal to the length of the original document being copied. Then when the trailing edge of the original document passesfeeler 294, the latter closes switch SW-3 to energize the cutoff knife solenoid SOL-2 (see also FIG. 16). In this way the copy paper 40 is cut to the length of the original document. Such operation assumes of course that a four-ganged switch SW-2, Which is the mode selector, is transferred to the left relative to FIG. 16, so as to select the document mode.
For card copying, the machine and the electrical control circuit operate quite differently. The mode selector switch SW-2 is transferred to the right relati e to FIG. 16, and the feed button 298 (FIGS. 12 and 13) is manually depressed to drive downwardly afeed lever 300 mounted for vertical movement upon avertical panel 312 bypins 302 engagingvertical slots 304 formed in thepanel 312 bypins 302 engagingvertical slots 304 formed in the lever. The lever is connected by means of apivot pin 306 to arotatable segment 308 pivotally mounted upon a shaft 310 journaled in thepanel 312. The downward motion of the feed lever rotates the shaft 310 counterclockwise relative to the view of FIG. 12. At the opposite end of the shaft is secured alink 314 by which the shaft may be rotated clockwise under control of a pair ofparallel links 316 connected by apivot pin 318 to thearmature 320 of a feed break solenoid SOL-3 (see also FIG. 16).
Adetenting leaf spring 322 is secured to thepanel 312 by means of abracket 324 andsuitable fasteners 326. The detenting spring is bent to form aprojection 328 which bears against an areuate edge of themember 308 and engages either of twodetents 330 formed therein to hold thesegment 308 in either of two position.
The position illustrated in FIGS. 12 and 13 is the one assumed by the segment when the copyingmachine 20 is in the document mode. Under these circumstances thefeeler 296 of switch SW-lis not engaged by anactuator 334 connected by a pair ofupstanding lugs 336 and a pin 33% to a pair ofupstanding lugs 340 bent from abracket 362. Thebracket 342 is formed with downwardly bent lugs 344 at either end thereof which receive the shaft 310. So long as the element just described are in the illustrated document mode position, the switch SW-d operates the feed roller clutch solenoid SOL-l only when thefeller arm 2% is actuated by a document.
But when thefeed button 298 is manually depressed to drive lever 31M downwardly, segment 36% is rotated counterclockwise, relative to the view of FIG. 12, and is thereby shifted to the other dented position. This rotation ofsegment 308 turns shaft 310, so that alug 332 bent upwardly from the end of theactuator 334 and situated eccentrically of the shaft 310 is then raised by member 3M to engage thefeeler arm 296 of switch SW-4l. As a result, switch SW-d is closed to energize the solenoid SOLl, which engages the drive to the copypaper feed rollers 76 and '78 for card copying operation. Thedetenting spring 322 holds theactuator 334 in this position to keep the switch SW-d closed throughout a card copying operation. In this use of the same switch SW-4 to control the paper feed for card mode as well as document mode operation, we again see how a conventional single purpose photocopier has been adapted to do double duty as a card copier.
During such operation cards which are delivered sequentially across the guide plate 245 by thecard feed rollers 122 and 1124 are then gripped between thesame rollers 52 and 5a which in the document mode serve to extract the original document from channel as. These rollers then feed each card in turn across the transparent plate 2d of the copyingstation 22. The plate 24 is made of glass and is supported upon a metal plate 35% having anaperture 352 therein to admit the light beam 26 from the lamp 223 (FIG. l). Aroof plate 354 cooperates with the glass plate 24 to define the channel through which the copied material passes.
A subsequent set offeed rollers 56 and 58 extracts the copied material, either a document or a sequence of tabulating cards, from the copyingstation 22 and ejects it to the left relative to the view of FIG. ll2. When the machine is in the card mode, thegates 70 are in the position illustrated in FIG. 12 and by the solid lines of FIG. I. In this position they direct the emerging tabulating cards downwardly across aguide plate 356 and throughpassageway 379 into the output bin I26. Alternatively, when the machine is operating in the document mode, thetray 60 is put in place over thepanel 62, and flange 64 strikes thegates 70 at alocation 71 above the center ofshaft 72, causing the gates to'rotate downwardly as shown by the dashed lines of FIG. ll. This in turn causes the documents emerging from between therollers 56 and 58 to be deflected across the top surface of the gates so that they fall into the tray till. When the tray so is removed, the gates spring back up to the card position under the influence of respective biasing springs 73 which are coiled aboutshaft 72. One end of each spring is anchored within an opening 75 in the shaft, and the other end presses upwardly against a flat 77 formed centrally of thegates 70 above a bifurcation defined by a pair of spaced hubs 79 (see FIG. 8). The biasing springs are laterally contained within this bifurcation.
in order to minimize the blank space between consecutive mailing address labels printed on theoutput strip 41, the card feed rollers ll22 and H24 run at higher linear speed than thefeed rollers 52 and 54. As a result, during the interval when one tabulating card lllfi has slowed down to the speed dictated byrollers 52 and 5d and the following tabulating card is still being conveyed at the faster speed dictated by the rollers in and 124, the second tabulating card catches up with the first one to some extent and thus overlaps it. Consequently, successive tabulating cards lilo arrive at the copyingstation 22 in an overlapping relationship reminiscent of shingles on a roof. This causes the consecutive address labels I38 to be printed closer together upon thecopy strip 41.
- iii Whenever conditions call for an automatic: termination of the card copying mode, the solenoid SOL-3 is energized. This causes it to retract itsarmature 320 and pull the parallel connectinglinks 316 to the left relative to the view of FIG. 12, so as to rotate themember 314 and shaft 310 clockwise. When so rotated, the shaft 310 retracts thelug 332 ofactuator 334 from theswitch feeler 296, to open switch SW-4 and terminate energization of the copy paper feed roller clutch solenoid SOL-1. At the same time, the shaft 310 rotates thesegment 308 clockwise to return it to its original detented position, so that the mechanism remains out ofthe card mode until the next time that thefeed button 298 is manually depressed.
The reader is now in a position to appreciate the electrical logic of FIG. 16. Switch SW-1 of FIG 16 turns themachine 20 on and off by controlling the AC supply from a pair ofpower input terminals 360 and 362. This switch is physically located on the front panel 364 of themachine 20 as seen in FIG. ii. Also located on that panel is switch SW-2 of FIG. 16, which is a double throw device used to select between the document and card copying modes ofthemachine 20. Electrically switch SW2 comprises four individual switches SW-2.l through SW-ld in ganged relationship (dashed line 366). Terminal D ofeach switch is the document mode terminal, and terminal C is the card mode terminal. Switches SW-3 andSW 2 of FIG. 116 are represented also in FIGS. 11, 12 and 13. In connection with the latter two figures it was explained that, in the docu ment mode, switch SW-4 closes during the time that a document is fed past thefeeler arm 296, as a means of detecting the length of the document, so as then to actuate the cutoff knife solenoid SOL-2 and sever a matching length of copy paper 410.
In contrast, when the machine operates in the card copying mode, switch SW-3 is cut out of the circuit by the mode selector switch SW-2 so as to disable the cutoff mechanism lid to provide an output in the form ofa continuous strip rather than discrete copies. Switch SW-d, on the other hand, is still needed to advance thecopy paper 41, but is manually closed by the operating thefeed button 298 and latched in that position by the detenting relationship betweensegment 308 andspring 322 of FIG. 12. Subsequently, when solenoid SOL-3 of FIGS. 112 and i6 is energized, the detenting segment 303 is shifted and the switch SW4 is allowed to reopen (dashed line 363) to terminate card mode operation.
Solenoid SOL-3 is energized to accomplish this, when the selector switch SW-2 is in its card mode position, by either of two switches SW-7 and SW-S of FIG. 16 which are electrically in parallel. Switch SW-7 is physically represented in FIGS. 1 and 5, where it is seen that is is positioned to sense the tabulating card deck 116. This switch closed when the tabulating card deck is exhausted, i.e. when the card copying run has been completed. Switch SW8 is physically represented in FIG. i where it is seen positioned adjacent thecopy strip 41 as it is unreeled from the supply roll 43. The feeler arm 371 of this switch senses the copy strip, and closes the switch when the strip is exhausted or is broken upstream from the feed rollers '76 and '73. Accordingly, in the card mode, when the copying of the tabulating card deck 1116 is completed, or thecopy paper strip 41 is exhausted or broken, the solenoid SOL3 is energized to release the feed switch SW-4 and terminate the feeding of copy paper M.
A further switch SW-S, which is represented only in the electrical diagram of FIG. 16, is mechanically operated by a suitably driven andtimed cam 370 to provide time delay. This time delay relates to the document mode, and its purpose is to allow the leading and trailing edges of the copy paper strip 40 to travel from the point of cutoff by the knife mechanism 80 down to the printing station 33, and to allow the leading and trailing edges of the original document, after engaging thefeeler arm 2% ofswitch SW 3, to travel throughchannel 46 to reach the copyingstation 22, before the copyinglamp 28 and theelectrostatic charging device 86 are turned on (for leading edges) or off (for trailing edges). For this reason,terminals 373 energized by the switch SW-S are provided for connection to the'lamp 28 and charger 86 (not shown in FIG.
16). Since the electrical connections to the lamp and charger and the mechanical time delay mechanism are all conventional equipment on copying machines which are now being marketed, it is unnecessary to illustrate or describe them in any greater detail.
in another example of the way in which the existing mechanism for copying documents is adapted for cards according to this invention, the same switch SW-S is used also to control the card feed clutch solenoid SOL-4 in the card mode, so that the tabulating cards 116 are not fed from thecard hopper 120 to the copyingstation 22 until the copyinglamp 28 and the electrostatic charger 36 have been turned on to render the machine operative for copying.
Flnally, there is a switch SW-9 which is ganged (dashed line 372) with switch SW-8 of FIGS. 1 and 16. Switch SW-9 is in series with the card feed clutch solenoid SOL-4, and opens to disrupt the feeding of cards when the feeler arm 371 (H0. 1) detects a break in the continuity of thecopy paper strip 41. In the card mode, switch SW-9 acts immediately to deenergize the card feed clutch solenoid SOL-4 and stop the feeding of cards abruptly when thepaper copy strip 41 is no longer available for copying them. This immediate card feed cutoff makes it unnecessary to wait for switch SW-il to produce a delayed deenergization of solenoid SOL-4 via dashedline 368, and switch SW-4.
A typical sequence of operations of themachine 20 will now be described in detail with reference to the electrical logic of FIG. 16. To begin with, the machine is turned on by closing switch SW-1 on the front panel 364. Let us assume that one or more documents are to be copied first. To set themachine 20 in the document copying mode, the selector switch SW-2 on front panel 364 is transferred to its D terminals of FIG. 16. As a result, switch SW-2.4 disables the branch of the circuit which includes switch SW-9, and the card feed clutch solenoid SOL-4, while switch SW-2.3 disables the copy paper feed release solenoid SOL-3. In addition switch SW-2.3 prevents the card sensing switch SW-7 and the copy paper sensing switch SW-S from operating the knife solenoid SOL-2; instead, the switch SW-2.1 connects the knife solenoid SOL-2 to the document trailing edge sensing switch SW-3.
At this point the operator inserts a single document into thechannel 46 until it is grabbed by the drivenrollers 51 and 53. When the leading edge ofthe document contacts feeler 296, it closes switch SW-4 and thereby energizes the solenoid SOL-1 to clutch thedrive chain 150 to the copypaper feed rollers 76 and 78, so that copy paper 40 is fed downwardly from these rollers starting at the time that the document leading edge passes the switch SW-4. Furthermore, the latter switch remains closed for the entire time it takes for the length of the original document to pass theswitch feeler arm 296, so thatfeed rollers 76 and 78 continue to unreel a length of copy paper 40 equal to the length of the original document. Then when the trailing edge or the original document releases thefeeler arm 296, switch SW-4 opens to deenergize solenoid SOL-l and stop feeding copy paper 10. Also when the railing edge passesfeeler arm 294, switch SW-3 closes and energizes solenoid SOL-2 to actuate the cutoff knife mechanism 80, severing the copy paper 49 to the length of the original document,
The time which it takes the leading edge of the original document to pass through thechannel 46 from the switch SW-4 to the copyingstation 22 is equal to the time that it takes the leading edge of the copy paper strip 40 to pass from the point where it was last severed by the cutoff knife mechanism 80 down to theprinting station 38. Similarly, the time that it takes the trailing edge of the original document to pass from the switch SW3 through the copyingstation 22 is equal to the time that it takes the freshly severed trailing edge ofthe copy paper 40 to pass downwardly from the point where it was severed by the cutoff knife mechanism 80 and through theprinting station 38.
While themachine 20 is in this operating mode, a plurality of document copies can be made only by repeating the process; i.e. an original document must be manually inserted into thechannel 46 once for each copying cycle of themachine 20.
In contrast, in the card copying mode, themachine 20 is conditioned for a continuous copying run during which a steady stream of tabulating cards 116 are copied in succession, and the operation of the machine continues automatically in this manner until it is deliberately shut off or the tabulating cards 116 have all been copied, or thecopy paper strip 41 is exhausted or suffers an accidental break.
ln order to operate in the card copying mode, the operator fills thehopper 120 with the tabulating cards 116 and puts thecard weight 117 over the deck. He also replaces the 8 /2 inch document width copy paper roll 42 upon theshaft 47 with a roll 43 containing the narrower widthcopy paper strip 41 which is suitable for address labels. Then the selector switch SW-2 is transferred to its card copying mode position. Switch SW2.1 then takes control of the cutoff knife solenoid SOL-2 away from the document trailing edge sensing switch SW-3, switches SW-2.2 and 2.3 respectively give control over the cutoff knife solenoid SOL-2 and the copy paper feed release solenoid SOL-3 to the parallel combination of the card sensing switch SW-7 and the copy paper sensing switch SW-B, and switch SW2.4 gives control over the card feed clutch solenoid SOL-4 to the copy paper sensing switch SW-9 and the time delay switch SW.S.
The operator then presses down thefeed button 298 and itslever 300 for manual closure and locking of switch SW-4. That switch energizes the solenoid SOL-l which engages a clutch to connect the copypaper feed rollers 76 and 78 to themain drive chain 150, so that thecopy strip 41 is unreeled. At this moment the switch SW-S is still open, and the card feed solenoid SOL-4 is still deenergized along with the copyinglamp 28 and theelectrostatic charger 86. After the passage of the time delay governed by SW-S which is operated bycam 370, switch SW-5 then closes, turns on the copying lamp and charger, and energizes the card feed clutch solenoid SOL-4 through switches SW-9 and SW-2.4. Solenoid SOL-4 consequently engages clutch 190 to drivepickers 156 andfeed rollers 122 and 124, which then begin delivering the tabulating cards 116 sequentially to the copyingstation 22. Operation in the card copying mode will then continue automatically in this manner so long as switches SW-7 and SW-8 are open and switch SW-9 is closed.
There are two alternative conditions which automatically terminate card copying operation. On of these is exhaustion of the tabulating cards in the hopper when the card copying job has been completed. When cards 116 are no longer sensed by the switch SW-7, that switch closes to complete an energizing path for the cutoff knife solenoid SOL-2 through switches SW-4 and SW-2.2. Solenoid SOL-2 then actuates the cutoff knife mechanism 80 to sever thecopy paper strip 41 as is appropriate after copying all the cards 116 in thehopper 120. In addition, the closing of switch SW-7 completes a circuit to the feed release solenoid SOL-3 through switches SW-4 and SW-2.3, so that solenoid SOL-3 then releases thefeed control lever 300 to open the switch SW-4, This in turn deenergizes the solenoid SOL-l to declutch the copypaper feed rollers 76 and 78 and discontinue the delivery of thecopy paper strip 41. in addition, after the passage of the time delay, the switch SW-5 opens to deenergize solenoid SOL-4 and disengage thecard feed clutch 190, since thecard hopper 120 is now empty.
The other condition which automatically terminates card mode operation is exhaustion or discontinuity of thecopy paper strip 41 upstream from thefeed roller 76 and 78. When this happens, arm 371 is transferred and SW-8 closes. As a result, the solenoid SOL-3 is energized to release thelever 300 and open the switch SW-4. This declutches thepaper feed rollers 76 and 78, which are no longer needed once thecopy paper strip 41 is no longer there to be fed. The same movement of the sensing arm 371 which closes switch SW-8 also opens the other copy paper sensing switch SW-9, so that upon interruption of thecopy paper strip 41 the solenoid SOL-4 is immediately deenergized and the clutch 190 disengaged to stop feeding tabulating cards 116 to the copyingstation 22.
During card copying operation the successive tabulating cards 116 emerging from the copyingstation 22 under control of therollers 56 and 58 pass between the gatingmembers 70 and theplate 356, and then pass below thepanel 62 and fall throughpassageway 379 intooutput bin 126 where they are caught upon the floatingcard catcher tray 128. At the beginning of the card copying run, the catcher tray is near the top of theoutput bin 126 so that the tabulating cards can not flip over as they fall, but instead land flat upon the tray. This insures that the cards will not be damaged as other cards accumulate above, and also insures that they are deposited in the proper sequence. But then as cards accumulate on thetray 128, the effective card catching surface becomes the rising top of theoutput deck 380. Therefore, in order to made room for the steadily increasing thickness of that deck, and to keep the effective card catching surface near the top of theoutput bin 126 so that subsequent cards are caught in the same way, the tray 1211 is mounted upon a floatingmechanism 382 which slowly lowers it toward the bottom of thebin 126 in response to the increasing weight of theoutput deck 380.
As seen in F165. 1, 8 and 9 thetray 128 is in the form of a plate having dependingears 384 at opposite sides thereof. Each of these ears is provided with anupper roller 386 journaled on astub shaft 388 and alower roller 390 journaled on astub shaft 302. Thelower rollers 390 are set somewhat forwardly on theupper rollers 386, and all four rollers are formed withperipheral grooves 394 to receive respectivevertical rail 396 on opposite sides of theoutput bin 126. The center of gravity of thetray 128, with or without theoutput deck 380, is forward of therails 396, causing the entire assembly to be gravity biased so that therollers 386 and 390 on each side clasp their associated rails therebetween, to suspend the catcher tray 1211 at any required height along the rails. In addition, therollers 306 and 390 roll on therails 396 to permit relatively easy adjustment of the vertical position of the catcher tray 1211.
Each of therails 396 is supported at its top by tongue-ingroove engagement with a holdingbracket 398 which is secured to therear wall 400 of theoutput bin 126. At their lower ends therails 396 have extension pins 402 which are received within appropriate openings in thefloor plate 404 of theoutput bin 126. Therear wall 400 is formed with acutout 401 at the top which defines the lower edge ofpassageway 379.
Thecatcher tray 128 is held at whatever height is appropriate to the instantaneous size of the tabulatingcard output deck 380, by a counter balancing mechanism comprising acoil spring 406 anchored at its lower end to atab 408 which projects from therear wall 400. The upper end of the spring is hooked through a suitable opening in the center ofa bar 410. The opposite ends of this bar have openings to which are secured the ends ofrespective wires 412. The wires extend upwardly from the bar 410 and are wound first about thesmaller diameters 414 and then about thelarger diameters 416 of a pair of compound pulleys, which are rotatably mounted by means ofstubshafts 418 on the rear wall400. FRom thelarger diameter section 416 of each compound pulley thewires 412 extend to therespective ears 384 of thecatcher tray 128, and are secured toopenings 420 therein. By this means the counterbalancingspring 406 exerts a continuous, yielding upward force on thecatcher tray 128. As the weight of thecard output deck 380 increases, thecatcher tray 128 sinks within theoutput bin 126, and thewires 412 unreel from the compound pulleys 416, 414, raising the bar 410 and extending thespring 406.
Thecards 380 are further confined by afront panel 422 which is a continuation of thetop panel 62, and which bends over into engagement with thefloor panel 404 at the bottom of the bin. in order to confine thecards 380 laterally, a pair ofmoveable side panels 424 are provided, which are held in place by the horizontal tension exerted by a pair ofcoil springs 426 engaging theside panels 424 at one end and hooked at the other end intosuitable openings 428 formed in therear wall 400. At the top, theside panels 424 are formed withpins 430 which extend through suitable openings inlugs 432 bent from opposite sides of the holdingbracket 398. At the bottom theside panels 424 are formed withsimilar pins 434 which engage suitable openings in thefloor panel 404. Thepins 430 and 434 rotatably mount theside panels 424 so that either panel can be swung aside against the force of itsspring 426, to provide access to the bin for removing thecard deck 380. Afterwards thespring 426 returns thepanel 424 to its original position.Lugs 427 bent from therear wall 400 serve to limit the springbaised motion ofpanels 424, and to define their rest positions.
Theentire output bin 126 is supported upon thefront panel 436ofthe copying machine 20 by means ofa pair ofbrackets 440 bent from the binrear wall 400. Thegate shaft 72 passes through openings in these brackets, and in turn is supported on the copyingmachine side panels 157. Near the lower end of theoutput bin 416 areslots 441 which engage downwardly overfastener shanks 443 protruding forwardly from the copyingmachine front panel 436. Theshanks 443 are provided with enlarged fastener heads 442, which serve to retain theshanks 443 within theslots 441.Enlarged openings 444 communicate with theslots 441 to provide for initial engagement with theenlarged heads 442.
FIGS. 10 and 11 provide a detailed view of the mechanism which delivers the copy paper strip to theexit 104 and winds it up on thetakeup reel 132 during card-copying operation. Roller in FIG. 1 is conventionally driven by themain drive chain 150, and rotates on ashaft 450 suitably journaled in theside panels 157 of themachine 20. This roller has looped thereover one end of each of fourconveyor belts 106, the upper strands of which move to the left (as seen in FIGS. 1, 10 and 11) in response to counterclockwise rotation of theroller 110. Thusbelts 106 convey theoutput strip 40 or 41 toward themachine exit 104. The fourconveyor belts 106 span a breadth which is adapted to convey the 8 /2 inch width of document-sized copy paper 40 when the machine is used in the document mode, while the twoinnermost belts 106 are sufficiently closely spaced to carry the narrower width ofcopy paper strip 41 which is used for address labels. Theconveyor belts 106 also act as drive belts to rotateroller 112 upon ashaft 452 which is supported betweenmachine side panels 157. Theroller 112 is provided withgrooves 456 for keeping theconveyor belts 106 in proper alignment, and similar grooves (not shown) are preferably formed on theroller 110.
Theroller 112 is further provided withadditional grooves 458 for proper alignment ofa further set ofconveyor belts 108 which are looped thereabout and are driven by theroller 112. Thebelts 108 serve to convey the copymachine output paper 40 or 41 the rest of the way toward theexit 104. The four of them are spaced widely enough to accommodate the 8 /2 inch regular document width of copy paper 40, which the twoinnermost belts 108 are properly spaced to support the narrower width of address labelcopy paper strip 41. The other ends ofbelts 108 are looped about theroller 114 and are engaged ingrooves 460 thereof for proper alignment. Theroller 114 is secured to ashaft 462 which is journaled in a pair ofside panels 464 of a reelmechanism supporting member 465 located at themachine exit 104. These side panels are formed withhooks 466 which engage over theshaft 452 to keep the supportingmember 465 properly positioned. Themember 465 also includes afloor panel 480.
In the document mode, as each copy emerges from theexit 104 upon theconveyor belts 108, it is manually retrieved by the operator ofthe copyingmachine 20. But in the card mode, as thecontinuous label strip 41 emerges from theexit 104, it is taken up continuously upon areel 132. The takeup reel is secured to a shaft- 136 provided withlarge diameter rims 138 at the opposite ends thereof. Therims 138 serve as lateral containment for theroll 134 oflabel output strip 41, and also serve as a driving means of theshaft 136 andtakeup reel 132. In order to accomplish this latter function, theenlarged rims 138 are in frictional driving engagement with theroller 130 which in turn is secured to adrive shaft 467 to rotate the roller. Thedrive shaft 467 has agear 468 at one end which in turn meshes with agear 470 on theshaft 462 of theconveyor belt roller 114. Consequently, theconveyor belts 108 provide the drive for thetakeup reel 132.
Theshaft 136 rotates on, and is gravitationally retained in place upon, thearms 462 of aU-shaped bracket 474. The bracket in turn is mounted on arod 476 which is supported at either end by thepanels 464 and which extends through thebracket arms 472. Asecond rod 478, also supported at either end by thepanels 464, engages the lower end of thebracket 474 in order to limit its rotation about therod 476.
When the copying machine has completed its work, the reel I32 and shaft [36 carrying thelabel output roll 134 are removed therefrom and operatively mounted in a conventional labeling machine.
Any suitable means, such as a conventional-type photocell arrangement, may be used to insure that the locations of the strip cutting lines are between the successive field of said addresses. Further the copy paper 40 may be provided with conventional indicia or pin feed holes so that theoutput strip 41 may be efficiently used in conventional-type labelling equip ment. Here again suitable means are provided for synchronizing the movement of such an output strip and the feed of said tabulating cards 116.
It will now be appreciated that the present invention provides a novel system, having both method and apparatus aspects, for the rapid automatic printing and application of large numbers of mailing address labels; the system dispensing with conventional printing presses and plates, and thus avoiding the multitude of disadvantages which they entail. In addition, the card copying apparatus of the system involves several novel and advantageous modifications to an existing photocopying machine which enables it to copy a continuous stream of tabulating cards.
