Hereinafter especially with reference to Figure 17 to 43 pair so far the course of work of the equipment of describing set forth.

Figure 17 shows the final step that utilizes the 7 knitting tubular article M of going out of the pin in the circular bed in the circular knitter 3.The knitting operation of tubular article originates in an edge B1, and this edge B1 is positioned at the bottom in Figure 17, and will keep opening wide in final finished product.When tubular article M was socks, described edge had constituted the elasticity stocking blank of socks.Last knitting step is the edge B2 that is shaped, and this edge B2 is designed to be about to be sewn, to form the stitching leading section or the undertoe portion of end article.

In forming process, tubular article M makes itself in the syringe 5 and the gap/space between theways 15 of pin T, and being syringe 5 and described ways more exactly, stretches out between the part of coming with respect to the input end of suction catheter 13.In this step, get up along intermediate isolatingdevice 19 closures that suctioncatheter 13 is provided with, and thereforejaw 21 and 22 graspsways 15, keeps it to be positioned at the position ofsuction catheter 13 inside.Best, also grasp one of to major general'sslide block group 31 and 32, these slide blocks are engaged on the ways simultaneously.That part of suction catheter betweeninput end 13A and intermediate isolatingdevice 19 keeps a negative pressure by a vacuum noz(zle) 14, and described vacuum noz(zle) 14 is provided with near intermediate isolatingdevice 19 at the input side of suction catheter 13.Vacuum noz(zle) 14 is connected on a drawing fan or the similar device (not shown).

Can be pushed into its extended position by means of pressure-air in advance from therod member 15C thatways 15 is extracted, described pressure-air infeeds by the jaw in the insulating element 19.At this extended position place, thehead 15E ofrod member 15C is positioned at the top onsketch plate 59 planes of living in, and describedsketch plate 59 is opened, so that allow the head of itself to pass through.Theclosed rod member 15C that can cause takes place and keeps cooperating withhead 15E above these sketch plates itself by thehole 65 between thesketch plate 59 in sketch plate 59.Therefore 15 inside lack pressure even this just means ways, androd member 15C will remain on extended position, even when the jaw on the insulatingelement 19 is opened,rod member 15C will remain on extended position.In this structure, be fixed inrod member 63 on thesketch plate 59 facing to the axis ofrod member 15C, and be placed in part at least in the pedestal that in describedrod member 15C, is formed at below thisrod member head 15E, so that for the reason that will understand hereinafter, reduce radially inhibition torod member 63.

When tubular article M has utilized the circular bed of pin 7 in the circular knitter 3 to make, this tubular article M is unloaded from pin, and, be positioned at the position shown in Figure 18 until it because the suction function in thesuction catheter 13 is sucked alongsuction catheter 13; That is to say until it and be resisted against on the intermediate isolating device 19.Article M is guided byways 15 along moving ofsuction catheter 13, makes article M slide in the inwall ofsuction catheter 13 and free clearance between theways 15 or space.In order to make article M pass the lateral surfaces that slideblock 31 and 32 works,slide block 31 and 32 is closed in an alternating manner and open, thereby, in the process that article M passes through, one group of slide block is only arranged, 31 or 32, cooperate with ways 15.By this way, tubular article M can pass the zone that is provided with described slide block, and can arrive the position shown in Figure 18.

In order to make tubular article M arrive theoutput end 13B ofsuction catheter 13 in such a way, promptly it rests on the wall that is formed by thesketch plate 59 that is in position shown in Figure 19, intermediate isolatingdevice 19 byjaw 21 and 22 mutually away from being opened.Can interrupt by the swabbing action of vacuum noz(zle) 14 this moment, provides swabbing action by aspirating air pipe on the contrary, and described aspirating air pipe is connected on thechamber 53 ofmovable fixture 39 inside by means of joint 57.A kind of swabbing action in back also can be enabled in previous step, that is to say in the step shown in Figure 18 and enables.

By this way, tubular article M arrives the position shown in Figure 19, and wherein, it rests on the wall that is formed by thesketch plate 59 that is in closure state.Equally in this case, the motion of tubular article M is guided byways 15, and this moment,ways 15 extended to sketch plate 59.Slide block 33 is opened, so that allow article to pass through, wherein saidslide block 33 before had been closed, and was used for the processsupport guide member 15 that the jaw on intermediate isolatingdevice 19 is opened.Opening ofslide block 33 can be in such a way carried out synchronously with the next closing motion of intermediate isolatingdevice 19, and promptlyways 15 will be fixed on one ofsuction catheter 13 inside centre position substantially always suitably.Selectively, by cooperating with hole on the wall that is formed bysketch plate 59, can obtain the cross-brace to ways, be that part supports at least.

The effect of subsequent step is that tubular article M is extracted out fromsuction catheter 13, and its inboard turnup is come out, and to implement " locked in " operation, thus the terminating edge B2 on these article is united by a seam, and forms the leading section of sealing on it.

For this reason, (only expressed the end regions of suction catheter 13) in Figure 20 as can finding out,sketch plate 59 is subjected to displacement by means of rotarymain shaft 61, so that make therod member 63 that is fixed on thissketch plate 59 radially outward move.

Becausesketch plate 59 androd member 63 all are positioned at the top ofoutput end 13B, and therefore be positioned at the outside ofsuction catheter 13, so the disengaging movement ofrod member 63 can extend to such position, in this position,rod member 63 arrives the outer radial position (shown in Figure 20) outside the bar that an edge that is positioned at bysuction catheter 13 forms.In this position, the fabric portions of the B1 that keeps to the side among the article M promptly is located substantially on the outside of the bar that is formed bysuction catheter 13 by tensioning in such a way.

Incase rod member 63 cooperates with tubular article M, the estable formula on theways 15stretches rod member 15C and will retract within thepart 15B on theways 15 so, reduces the pressure of thepart 15B inboard ofways 15 thus.The retraction of rod member is by means of the realization that is used for of extension spring 15D.In Figure 20, shownrod member 15C is in its advanced position.

As arrow f39 was shown, by means of the downward vertical motion ofdevice 39,rod member 63 arrived such position, and in this position, they laterally are arranged side by side in the outside with respect to theoutput end 13B of suction catheter 13.Tubular article still engages withrod member 63, and thus along withrod member 63 moves, and is wrapped in the outside ofsuction catheter 13 in the zone around theoutput end 13B of suction catheter 13.The descending motion ofdevice 39 continues torod member 63 and discharges from tubular article M (Figure 22) fully.

In order fully tubular article M to be extracted out from the inside of suction catheter 13, and by making tubular article M be nested with on the outer surface of suction catheter 13 its inboard turnup is come out, pusher 47 is compressed against tubular article M and goes up (Figure 23), and install 39 and further move down at this moment, as arrow f39 is shown (Figure 24).By this way, as arrow f39 was shown, further moving down of movable fixture 39 can cause tubular article M to be spurred along the outer surface of suction catheter 13, arrived the position shown in Figure 24 until device 39.In this position, tubular article M is positioned at the outside of suction catheter 13 fully.It also can be with respect to by the circular knitter 3 knitting structures that form inboard turnup being come out.Pusher 47 can separate once more, tubular article M is discharged, because the elasticity (the especially elasticity of start edge B1) of article itself, tubular article M still keeps position shown in Figure 25, and described article itself are grasped on the outer surface of suction catheter 13.If tubular article M ten minutes is long, can the repeating repeatedly of device 39 that has the pusher 47 that is in the close position so to down stroke, after pusher 47 is opened in advance, will install 39 at every turn and upwards return, in the upward stroke of device 39, upwards spur tubular article once more to prevent pusher 47.

As among Figure 24 as can be seen,suction catheter 13 has two slit 13D, these twoslit 13D originate inoutput end 13B, promptly originate in the edge ofsuction catheter 13, and extend particular length along a direction that is parallel to the suction catheter axis.The effect of these slits is to makecarriage 73 can grasp tubular article M, and makes its part skid offsuction catheter 13, comes by the leading section sealing of sew application with article.But before implementing this operation, tubular article M may need to carry out angle orientation.

In fact, be used for the suture that the leading section to described article seals and have point-device orientation with respect to article itself, described article are a bag shape usually, that is to say the heel area that is used to form socks or stocking and the fabric portions in toe zone.Suture must have split hair position with respect to these bags portion on the fabric.In order suitably tubular article to be positioned before sew application, forming mark such as the coil of the yarn that is different from described article yarn by means of a small amount of color in knitting process on described article just is enough to realize.Thus obtained mark is surveyed by means of a photoelectric sensor (not shown), and described photoelectric sensor is positioned near the output end 13B of suction catheter 13.This moment, the proper angle orientation of tubular article M realized by make part 13C on the suction catheter 13 be rotated around himself axis by means of actuator 35.This rotation is to make described equipment arrive position shown in Figure 25 from position shown in Figure 24.In fact, the difference of two accompanying drawings only is, is formed at the position difference of the slit 13D the output end 13B of suction catheter 13 near.The difference of angle position has represented part 13C on the suction catheter 13 with respect to the rotation amount of the remainder of conduit itself in two accompanying drawings, and described rotation is used to make that tubular article arrives correct angle position.

In the step of described angle orientation, perhaps under any suitable situation,device 39 all can upwards return, and arrives the position shown in Figure 26 until it,pusher 47 remains on its advanced position, does not promptly come in contact with tubular article in the described process that moves upward.

Arrived the tip position shown in Figure 26 in case install 39, pusher will be closed once more so, near the 13B of the output end ofsuction catheter 13 tubular article M is pressed against on the outer surface of suction catheter 13.In case tubular article M is by on the outer surface that it is pressed against thepart 13C on thesuction catheter 13 and be joined together once more,part 13C can be rotated once more so, so thatmake slit 13D, that is to say to be positioned on the axis and plane that includes thepart 13C on thesuction catheter 13 perpendicular to plane shown in Figure 26 to the home position that arrivesthem.Part 13C on thesuction catheter 13 can not cause tubular article M that angular movement takes place by means of described the rotatablely moving that actuator 35 obtains once more, tubular article M was pusheddevice 47 and was fixed up this moment, preferably was coated with a kind of material with great friction coefficient on the pusher 47.By this way, thepart 13C on thesuction catheter 13 is rotated with a kind of sliding type in tubular article M inside, promptly in the enterprising line slip of the inner surface of tubular article M.

In the structure shown in Figure 26, tubular article M is in the correct angle position of carrying out follow-up sew application, and therefore can be grasped by the carriage in the grippingmember 71 73.The carriage of drawing close mutually 73 is used for such decline purpose, moves to suctioncatheter 13 inside until them, enters the position shown in Figure 27, shows a longitudinal profile ofsuction catheter 13 in Figure 27 along a plane perpendicular to plane shown in Figure 26.Carriage 73 is positioned on the plane of an axis A who includes thepart 13C on thesuction catheter 13 thus, also has slit 13D on this plane.By this way, as arrow f73 illustrated among Figure 27, the disengaging movement ofcarriage 73 can be with the edge B2 tensioning of tubular article M, and makes two flaps on this edge draw close mutually thus.The disengaging movement ofcarriage 73 and its lifter motion combination are carried out, and arrive their final positions shown in Figure 28 thus.In the final stage ofcarriage 73 lifter motions,pusher 47 can be used for tubular article M is fixed up, and thus it be carried out longitudinal stretching once morenear suction catheter 13.

In this position, the edge B2 on the tubular article M stretches and tensioning in such a way by means ofcarriage 73, and promptly two flaps on this edge alignmutually.Carriage 73 has arrived a vertical position, thereby makes their bottom be slightly higher thanorthoscopic bar 77 and 79.Straight line pole 77 and 79 can be drawn close thus mutually, comes the correct position place on edge B2 to grasp tubular article M.This state schematically shows in Figure 29, and Figure 29 shows a longitudinal profile along a plane perpendicular to plane shown in Figure 28.Straight line pole 77 has been drawn close on fixed bar 79.In Figure 28, L1 and L2 have referred to two flaps on the edge B2, because the stretched operation that carries out of 73 couples of edge B2 of carriage in the grippingmember 71, two flap L1 and L2 draw close mutually.Described article can move down slightly and stretched by means of thedevice 39 that haspusher 47.

Figure 29 A is a schematic enlarged drawing, shows to see that the fabric flap L1 and the L2 that form the tubular article edge are about to be able to enclosed areas.As finding out in the schematic cross section of fabric, described fabric has a series of coil column X2 that are positioned atbar 77 and 79 tops, and the part in these coil columns is utilized and a kind ofly made than the yarn that yarn is thick in other coil column.Described thick coil column has formed the bigger fabric portions of thickness, and it rests on thebar 77,79 that is arranged side byside.Bar 77,79 need not to be pressed against on the fabric, on the contrary, can allow suitably to be free to slide, so that by cross directional stretch.Clamping action along the longitudinal utilizes this fact to be guaranteed, promptly utilizes than partly resting on thebar 77,79 than heavy weave that coarse yarn obtains, describedly is identified as FG than the heavy weave part in Figure 29 A.The part of being made up of coil column X2 on the tubular article will be removed in follow-up cutting in the operation, therefore compare with the yarn that tubular article M goes up in the remainder, and described part utilizes second-rate yarn to make usually.

In the sew application process, can be kept upright by means of being engaged in the swabbing action of sewing up the vacuum noz(zle) on the machinery 95 by the edge that coil column X2 forms by one, wherein said vacuum noz(zle) is identified as 102 generally in Figure 33 and 34.

By along moving by direction shown in the arrow f83,pectinate texture 83 is pushed to tubular article M at this moment,tooth 85 onpectinate texture 83 is inserted into by that row's coil column facing topectinate texture 83, that is to say the stitching coil or the coil inside of that row's coil column that is located immediately atstraight line pole 77 and 79 belows.As can in Figure 29 A, finding out, the coil of described coil column (being designated X1), its length is greater than the length of all the other coils in the described article, so that can make thetooth 85 on thepectinate texture 83 insert easily.

Pectinate texture 83 is along being controlled (referring to Fig. 6) by moving of direction shown in the arrow f83 byaforementioned actuator 89, and for the sake of clarity do not give in Figure 29 and illustrating.Straight line pole 77 and 79 closing motion and the motion ofpectinate texture 83 subsequently illustrate in Figure 30 to 32 successively, and Figure 30 to 32 shows aforementioned movement with the diagrammatic plan view form.

In case thetooth 85 on thepectinate texture 83 has inserted each coil that is formed by each coil column among the tubular article M, so movablystraight line pole 77 will bounce back, so that the member of sewing up machinery 95 can be inserted, described member is implemented sew application along the coil of the coil column that has been inserted coil column below wherein by the tooth on thepectinate texture 83 85.Sew application schematically shows in Figure 33.

Figure 33 shows pin 96, mouth 99 and the crocheting device of sewing up in the machinery 95 101.Can also seepectinate texture 83, the respective coil row that thispectinate texture 83 is inserted on the tubular article M are inner.In Figure 34, show seam area with the amplification form.In Figure 34, can also know and see that howpectinate texture 83 and correspondingtooth 85 form (two part 83A illustrate separately with the perspective view form with 83B) by two part 83A and 83B in Figure 16, they are joined together, andblade 87 is set between them, in this structure, described blade is in an advanced position, that is to say the position that is positioned at the rear with respect totooth 85.

Figure 35 illustrates the motion state of sewing up member in the machinery, and the motion state of pin 96 and crocheting device 101 especially, crocheting device 101 is used for feed suture F.In this exemplary embodiment, pin 96 is so-called piston type pins (piston needle), promptly a kind of pin that has an open and close member 96A.Such pin itself is that the present technique field is at present known, especially learns in the existing patent that can be quoted in this specification Introductory part.But, also can use the pin and/or the crocheting device of other type.Such as, can use latch needles or eye needle guide.The order of sew application can be known in Figure 35 and find out, and itself be known for the purposes of other types; Therefore, here need not to be described in detail.

But, it is pointed out that by sewing up pitch on the seam that machinery 95 and pin 96 make, promptly less than pitch by the coil of coil column X1 less than the pitch of pitch on thepectinate texture 83 and thetooth 85 on it.Especially, can be susceptible to pitch on the seam equal by the pitch of the coil of coil column X1 half or 1/3rd, and thereforeequal tooth 85 on thepectinate texture 83 pitch half or 1/3rd.

Figure 36,37 and 38 shows the subsequent step that the coil to coil column X2 cuts, and wherein thetooth 85 on thepectinate texture 83 has been inserted in the described coil.Implement this cut operation before, flap L1 and L2 on the tubular article M are grasped and are fixed by the supporting rod in the clampingcomponents 103 105, this moment, tubular article M linked together by seam, described seam is designated C in Figure 36 to 38, clampingcomponents 103 is carried on the stitching machinery 95 that seam C made.Even this just makes cutting after operation finished, also can fix tubular article M.Cut operation and realize, so that it is moved to position shown in Figure 37 from position shown in Figure 36 by moving theblade 87 that is placed in the pectinate texture 83.Because this motion,blade 87 can be cut off by all coils of coil column X2, and wherein thetooth 85 on thepectinate texture 83 is inserted into described coil inside in advance.

At this moment,pectinate texture 83 can arrive position shown in Figure 38, and tubular article M be fixed by supportingrod 105 away from described article, and described supportingrod 105 is provided with and draws close together mutually in advance for this reason.Seam C top cuts the residue of yarn and is removed byremoval system 107, andremoval system 107 is represented by a brush that in Figure 39 this brush has a horizontal axis that is parallel to bar 105, but in fact it can have structure shown in Figure 40.Enlarged diagram among Figure 41 shows the mechanism of action ofbrush 109, has a vertical axis in this case, is used to remove residual yarn, is identified as FR in the enlarged diagram of residual yarn in Figure 41.

In case described sew application, cut operation and residual yarn and remove operation and finish, so article M by turning inside-out once more with after presenting its final structure, these article M can be taken off from equipment, and described final structure is corresponding to the article of being made by circular knitter 3.For this reason, with respect to before by means of the action of the motion ofdevice 39 andslide block 47 with the operation that the inboard turnup of article comes out, carry out reverse operating.In such a way to the inside ofsuction catheter 13 apply negative pressure by a vacuum noz(zle) 16 (Figure 43) this moment, and promptly its leading section is sucked by mouth 16 by the article that seam C is closed, and is removed from equipment.

Around hinge axes 17, be convenient to remove operation by thepart 15B on theways 15 with respect to the motion ofpart 15A, thereby make thepart 15B on the ways be resisted against on the inwall ofsuction catheter 13 in an other side with respect to the side that is provided with vacuum noz(zle) 16, the passage of leaving over next broad transmits towards vacuum noz(zle) 16 for the tubular article M that sews up.

In case aforementioned operation is finished, equipment will be returned to structure shown in Figure 17 so, be used for next tubular article M is sewed up, and meanwhile, next tubular article M has begun the shaping on circular knitter 3.
