DETAILED DESCRIPTION- Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. 
- Figs. 1 and2 illustrate apharmacy packaging system 10 embodying the invention. The illustratedsystem 10 is a self-contained system that stores, retrieves, and packages pharmaceuticals (e.g., pills, drugs, narcotics, or other medications). Pharmaceuticals may also include nutraceuticals and other types of substances. Thesystem 10 securely stores all of the pharmaceuticals required by a facility in an organized manner. In addition, thesystem 10 allows a user to retrieve different combinations of those pharmaceuticals through an automated process. In some embodiments, thesystem 10 can be placed in a facility (e.g., a closed-door pharmacy) that supplies packaged pharmaceuticals to multiple locations. In other embodiments, thesystem 10 can be placed in a consumer pharmacy or in other locations where a variety of different pharmaceuticals are distributed directly to multiple patients on a regular basis, such as in a nursing home, a hospital, a correctional facility, a home residence, or the like. 
- In the illustrated embodiment, thesystem 10 includes astorage unit 14 and twoautomatic packaging units 18. Thestorage unit 14 stores a plurality ofcanisters 22, or containers or cassettes, containing a variety of pharmaceuticals. Thepackaging units 18 package pharmaceuticals from thosecanisters 22 into pouches for distribution to patients. In some embodiments, thesystem 10 may include fewer ormore packaging units 18. Additionally or alternatively, thepackaging units 18 may be positioned on both sides of thestorage unit 14. For example, thesystem 10 may include fourpackaging units 18, with twounits 18 positioned on each side of thestorage unit 14. Such an arrangement allows multiple,independent packaging units 18 to access the same pharmaceutical array. 
- As shown inFig. 3, thestorage unit 14 includes aframe 26 and agantry assembly 30. Theframe 26 includes a plurality of shelves or other supports for storing thecanisters 22 in an array of rows and columns. Eachcanister 22 is uniformly shaped and sized and may contain pharmaceuticals of the same or different type compared toother canisters 22. In some embodiments, theframe 26 may be, for example, about fourteen feet wide by six feet tall by four feet deep and may store up to 1000individual canisters 22. In other embodiments, theframe 26 may be larger or smaller for storing fewer ormore canisters 22, as needed by a particular facility. 
- The gantry assembly-  30 is coupled to the frame-  26 for retrieving canisters-  22 from within the frame-  26. The gantry assembly-  30 is a canister-moving assembly that is operable to move the canisters-  22 within the frame-  26. The illustrated gantry assembly-  30 is similar to the gantry assembly disclosed in U.S. Patent Application No. 12/870,045, filed August 27, 2010-  and published as U.S. Patent Application Publication No. 2011/0054668- , the entire contents of which are incorporated by reference herein. The gantry assembly-  30 includes a track-  34 and a robotic head-  38 that is operable to move along the track-  34 to retrieve the canisters-  22. The track-  34 is movable horizontally within the frame-  26 to align the robotic head-  38 with a specific column of canisters-  22. The robotic head-  38, or carriage assembly, is movable vertically along the track-  34 to align with a specific row of canisters-  22. When the robotic head-  38 is aligned with the desired canister-  22, the head-  38 grabs the canister-  22 and carries the canister-  22 to one of the automatic packaging units-  18, as further described below. The robotic head-  38 can also retrieve a canister-  22 from the packaging unit-  18 and return the canister-  22 to the proper column and row within the frame-  26. In some embodiments, the canisters-  22 may not be assigned the same location. In these embodiments, the robotic head-  38 may retrieve a canister-  22 from the packaging unit-  18 and return the canister-  22 to a random location. The packaging unit-  18 may then store the new location of the canister-  22. In some embodiments, a return location of the canister-  22 may be determined based on, for example, the frequency of use the canister-  22, the size of the canister-  22, or the like. 
- Fig. 4 illustrates one of theautomatic packaging units 18. Thepackaging unit 18 includes acabinet 42, a dispensingarea 46, and acontrol system 50. The illustratedcabinet 42 may be about two feet deep such that theentire system 10 is about six feet deep with apackaging unit 18 on each side of theframe 26. Thecabinet 42 contains equipment for packaging pharmaceuticals into pouches. In the illustrated embodiment, the packaging equipment includes afeed stock roll 54 and a take-up roll 58 that are positioned within thecabinet 42. Thefeed stock roll 54 unrolls the pouches, which are then filled with pharmaceuticals from thecanisters 22A in the dispensingarea 46. The pouch is run along a track underneath all of theactive canisters 22A and filled with the requested number and type of pharmaceuticals from theappropriate canisters 22A. Such an arrangement reduces the possibility of cross-contamination between thecanisters 22A and, thereby, the pharmaceuticals. Once a pouch is filled, the pouch is discharged from thecabinet 42 through anoutlet 62. In the illustrated embodiment, theoutlet 62 drops the filled pouches into atote 66 so the pouches can be retrieved by a user. In other embodiments, the packaging equipment may be configured to package the pharmaceuticals into blister packs, pharmacy vials, or other suitable containers. 
- In some embodiments, thepackaging units 18 may include rollers, castors, or other types of wheels. The wheels allow a user to roll thepackaging units 18 toward and away from thestorage unit 14 in a modular fashion. Such an arrangement provides redundancy by allowing each of theunits 18 to quickly and easily be replaced. In addition, thepackaging units 18 may be interchanged if pharmaceuticals need to be packaged in a different size and/or type of packaging container. 
- The illustrateddispensing area 46 is positioned on top of thecabinet 42 adjacent theframe 26 of thestorage unit 14. The dispensingarea 46 temporarily stores a series ofactive canisters 22A that are used to fill the pouches within thecabinet 42. In the illustrated embodiment, the dispensingarea 46 stores up to twentyactive canisters 22A at a time. Such an arrangement allows a pouch to be filled with twenty different types of pharmaceuticals. In other embodiments, the dispensingarea 46 may store fewer or moreactive canisters 22A. The illustrateddispensing area 46 includes motors and sensors that are temporarily connected to each of theactive canisters 22A. For example, one motor and one sensor may electrically connect to eachactive canister 22A to selectively open and close thecanister 22A and to monitor the amount (e.g., number, volume, etc.) of pharmaceuticals being dispensed from thecanister 22A. In particular, the motor of the dispensingarea 46 rotates a rotor within thecorresponding canister 22A to selectively dispense pharmaceuticals out of thecanister 22A. In some embodiments, selectively operating thecanister 22A includes rotating a base of thecanister 22A to dispense a pharmaceutical through an opening. When operated, thecanisters 22A drop pharmaceuticals into the pouches. In the illustrated embodiment, the pharmaceuticals are dispensed from thecanisters 22A via gravity. In other embodiments, the packaging equipment may generate a vacuum to draw the pharmaceuticals out of thecanisters 22A. Metering devices may also be coupled to eachactive canister 22A to help control the amount of pharmaceuticals being dispensed. 
- In some embodiments, theautomatic packaging unit 18 may include an inspection device that inspects the pharmaceuticals before they are packaged in the pouches. After the pharmaceuticals come out of theactive canisters 22A, the pharmaceuticals may be temporarily collected in an intermediate catch basin. A sensor (e.g., a camera, etc.) may inspect the pharmaceuticals in the basin based on, for example, color, shape, infrared images, shape recognition, or pill imprints. The sensor may alternatively inspect the pharmaceuticals with spectrography, magnetic resonance, or the like. Once the pharmaceuticals are verified, the pharmaceuticals can be released from the basin into the corresponding pouch. Inspection of the pharmaceuticals may be entirely automated or may involve a person (e.g., a remote operator who views images of the pharmaceuticals). 
- Thecontrol system 50 is electrically coupled to the packaging equipment and thegantry assembly 30 to control operation of thepackaging system 10. In particular, thecontrol system 50 coordinates movement of thegantry assembly 30 to move thecanisters 22 between thestorage unit 14 and thepackaging unit 18, controls operation of thefeed stock roll 54 to release a pouch, and controls when theactive canisters 22A positioned in the dispensingarea 46 are operated. The illustratedcontrol system 50 includes amonitor 70 mounted to ashelf 74 that extends from thecabinet 42. Thecontrol system 50 may also include a processor, a memory, and an input device (e.g., a keyboard) that allows a user to interface with thesystem 50. In some embodiments, themonitor 70 may include a touch screen. 
- Referring back toFigs. 1 and2, during operation, a user interacts with thepackaging system 10 through thecontrol systems 50 on thepackaging units 18. The user may input the name of a patient and/or a particular combination of pharmaceuticals needed. Once the necessary data is inputted, thegantry assembly 30 moves relative to theframe 26 to retrieve theproper canisters 22 from thestorage unit 14 and carry thecanisters 22 to the dispensingarea 46. In the illustrated embodiment, therobotic head 38 of thegantry assembly 30 carries onecanister 22 at a time, but alternates between carrying acanister 22 to the dispensingarea 46 and removing acanister 22 from the dispensingarea 46, thereby limiting excess movements of thegantry assembly 30. In some embodiments, thepackaging system 10 may include more than onerobotic head 38 or more than onegantry assembly 30. In these embodiments,multiple canisters 22 may be carried at a time between thestorage unit 14 and the dispensingarea 46. In some embodiments, a user interacts with thepackaging system 10 via a remote device (e.g., a tablet, smart phone, laptop, or client computer) that enables the user to remotely control or otherwise interact with thepackaging system 10. 
- After theproper canisters 22 are positioned in the dispensing area, the packaging equipment within thecabinet 42 fills a pouch with the desired pharmaceuticals. For example, a strip of pouches may be filled with a week's supply of assorted pharmaceuticals for a particular patient. By connecting twopackaging units 18 to thestorage unit 14, a user (or multiple users) can simultaneously input data and fill two strips of pouches with pharmaceuticals for different patients. In some embodiments, the packaging equipment may include a printer to print a patient's name, the date, the amount and type of pharmaceuticals contained within, a bar code, or other indicia on the pouches. Once a pouch is filled and labeled, the pouch is dropped into the correspondingtote 66. 
- As the pouches are being filled, thecontrol system 50 tracks and monitors the amount and types of pharmaceuticals within thesystem 10. For example, thecontrol system 50 can verify that a user is authorized to retrieve certain pharmaceuticals, that a patient has a prescription for a particular pharmaceutical, and the quantity of pharmaceuticals remaining in eachcanister 22. Thecontrol system 50 can also track where a particular canister of pharmaceuticals is positioned within the system 10 (i.e., whether thecanister 22 is currently stored in thestorage unit 14 or one of the dispensingareas 46, and in which row and column of theframe 26 thecanister 22 belongs). 
- In some embodiments, the filling of orders can be optimized by thecontrol system 50. For example, a user can input all of the orders that need to be filled by thesystem 10 in a given day. Thecontrol system 10 can then determine in which order to process those orders to minimize the number of times thecanisters 22 move between thestorage unit 14 and the dispensingareas 46 of thepackaging units 18. In other embodiments, thecontrol system 50 may optimize the orders such that all of the orders for a particular patient or facility are filled consecutively. In further embodiments, the user may program thecontrol system 50 so that a particular order is filled immediately and/or the orders are filled in the order in which they were requested. 
- In still further embodiments, thecontrol system 50 can be programmed to fill a spool of pouches with the same drug or other pharmaceutical. For example, thecontrol system 50 can fill a series of 50 to 500 pouches with an individual drug or narcotic for pharmacies, nursing homes, hospitals, or other facilities to keep as stock drugs in emergency drug kits. 
- As shown inFigs. 1 and2, thepackaging system 10 also includes tworefill areas 78 positioned above the dispensingareas 46 of thepackaging units 18. In other embodiments, thesystem 10 may only include a single refill area and/or therefill areas 78 may be positioned in different locations relative to thepackaging units 18. Therefill areas 78 may be manually stocked withcanisters 22 by a user. When one of thecanisters 22 stored within thestorage unit 14 is depleted, thegantry assembly 30 can remove the empty canister, place that canister in therefill area 78, and grab a replacement canister from therefill area 78. Thegantry assembly 30 can then position the replacement canister in the proper row and column within theframe 26. In some embodiments, thecontrol system 50 can alert a user when aparticular canister 22 is empty or near empty so that the user can place asuitable replacement canister 22 within therefill area 78 and input information notifying thesystem 50 of thereplacement canister 22. 
- The illustratedpackaging system 10 increases the speed at which pouches of pharmaceuticals can be filled at an on-site facility and reduces the possibility of errors when filling those pouches. In the illustrated embodiment, thesystem 10 can achieve a throughput of up to sixty pouches per minute, including verification, for eachautomatic packaging unit 18 included in thesystem 10. Theautomated system 10 also avoids cross-contamination caused by mixing pharmaceuticals between pouches through a common pathway. In some embodiments, the packaging equipment generates vacuum to remove dust and clean the pathways. In other embodiments, the packing system may use designate certain pathways to certain pharmaceuticals to reduce or eliminate cross-contamination. 
- In some embodiments, theautomatic packaging units 18 may operate separately from thestorage unit 14. In such embodiments, eachpackaging unit 18 may be a standalone packaging system for use in smaller pharmacies or other low-volume facilities. In addition, the dispensingareas 46 of thepackaging units 18 may be manually loaded, as needed, to fill specific pharmaceutical orders. 
- Figs. 5-9 illustrate apharmacy packaging system 110 according to another embodiment of the invention. Similar to thepackaging system 10 discussed above with reference toFigs. 1-4, the illustratedpackaging system 110 includes astorage unit 114 and multipleautomatic packaging units 118. As shown inFig. 7, thepackaging system 110 includes fourpackaging units 118, with twounits 118 positioned adjacent each side of thestorage unit 114 to accesscanisters 122. In other embodiments, thepackaging system 110 may include fewer ormore packaging units 118. 
- Referring back toFigs. 5 and6, thestorage unit 114 includes aframe 126 and agantry assembly 130. Theframe 126 includes a plurality of shelves for storing thecanisters 122 in an array of rows and columns. In some embodiments, panels may be coupled to and extend across theframe 126 to enclose theframe 126 such that thecanisters 122 are secured within thesystem 110. The illustratedcanisters 122 are non-motorized canisters suitable for storing pharmaceuticals. Thegantry assembly 130, or canister-moving assembly, is similar to thegantry assembly 30 discussed above and can move along theframe 126 to retrieve thecanisters 122. In the illustrated embodiment, thegantry assembly 130 is positioned between two arrays, or stacks, ofcanisters 122 such that thegantry assembly 130 can access thecanisters 122 on both sides of thestorage unit 114. 
- Eachpackaging unit 114 includes amotor base 134 positioned adjacent theframe 126 of thestorage unit 114 and a manifold 138 coupled to and extending from themotor base 134. The motor bases 134 are offset from the other shelves of theframe 126 and includeledges 142 for supportingactive canisters 122A. The illustratedmotor bases 134 are only offset from the other shelves a relatively short distance to reduce the range of horizontal movement required by thegantry assembly 130 to placecanisters 122 on or removecanisters 122 from theledges 142. In the illustrated embodiment, eachmotor base 134 supports up to twentyactive canisters 122A at a time in a single, horizontal row. In other embodiments, eachmotor base 134 may support fewer or moreactive canisters 122A and/or themotor bases 134 may be configured to support theactive canisters 122A in multiple rows (e.g., two rows of ten, three rows of seven, etc.). Eachmotor base 134 includes one or more motors operable to operate theactive canisters 122A to dispense the pharmaceuticals stored within thecanisters 122A. The motor bases 134 thereby provide dispensing areas for theactive canisters 122A. 
- As shown inFig. 5, themotor bases 134 defineopenings 146, or inlets, in theledge 142 that correspond to theactive canisters 122A. The motor bases 134 also include aswitch 150 adjacent eachopening 146. When acanister 122A is positioned on theledge 142, thecanister 122A communicates with theopening 146 and activates theswitch 150. Theswitch 150 indicates to themotor base 134 that a canister is currently positioned on theledge 142. The motors in themotor base 134 can then operate thecanister 122A (e.g., by rotating a disk on the bottom of thecanister 122A) to dispense pharmaceuticals into theopening 146. In some embodiments, an infrared beam may detect when pharmaceuticals pass through each of theopenings 146. The pharmaceuticals travel through themotor base 134 and are ejected through anoutlet 154 formed in a face of themotor base 134. Theoutlets 154 dispense the pharmaceuticals from themotor base 134 into thecorresponding manifold 138. 
- The manifold 138 directs pharmaceuticals from themotor base 134 toward packaging equipment of thecorresponding packaging unit 118. The motor bases 134 are positioned generally above the packaging equipment such that pharmaceuticals slide down the manifold 138 toward the packaging equipment. In the illustrated embodiment, themanifolds 138 are funnels or chutes that are generally triangular and may be formed of, for example, stainless steel. In some embodiments, each manifold 138 may include a cover to inhibit pharmaceuticals from bouncing out of themanifold 138. In such embodiments, the cover may be formed of, for example, clear plastic to help visually monitor operation of thesystem 110. In addition, the cover may be easily liftable or otherwise separable from the manifold 138 to facilitate cleaning themanifold 138. In some embodiments, each manifold 138 may include discrete tracks (e.g., raceways or pathways) to direct pharmaceuticals from the correspondingoutlets 154 in themotor base 134 toward the packaging equipment. 
- The packaging equipment of theautomatic packaging units 118 collect the pharmaceuticals from themanifolds 138 and package the pharmaceuticals into pouches. In the illustrated embodiment, eachpackaging unit 118 includes areceptacle 158 that communicates with thecorresponding manifold 138. Thereceptacle 158 collects all of the desired pharmaceuticals from the differentactive canisters 122A before delivering the pharmaceuticals in a single group to the packaging equipment. Acamera 162 is coupled to thereceptacle 158 to take photographs of the pharmaceuticals as the pharmaceuticals pass into the packaging equipment. In some embodiments, multiple cameras may be coupled to thereceptacle 158 to take photographs of the pharmaceuticals from different reference angles. The photographs can be checked by a computer and/or a pharmacist remotely or on-site to verify that the correct pharmaceuticals are being packaged. 
- In other embodiments, a camera (or other sensor) may be positioned at eachoutlet 154 in themotor base 134. In such embodiments, the camera can look at a pill from its origin and determine whether the correct pharmaceutical is being dispensed by comparing an image of the pharmaceutical to a stored image of the expected pharmaceutical. For example, the camera can compare a pill's color, contour, shape, size, and/or inscription to the color, contour, shape, size, and/or inscription of a known pill. 
- In the illustrated embodiment, the packaging equipment of eachpackaging unit 118 includes two feed stock rolls 166, 170 and a take-up roll 174. After the pharmaceuticals pass through thereceptacle 158, the pharmaceuticals are sandwiched between two strips of material (e.g., plastic) from the feed stock rolls 166, 170. The strips of material are then heat sealed together to form a pouch for the pharmaceuticals. In some embodiments, such as the embodiment shown inFigs. 10-15 and described below, eachreceptacle 158 may include a shutter or valve mechanism that temporarily stops the pharmaceuticals before they are captured in a pouch. Once formed, the pouches are wrapped around the take-up roll 174 to create a single spool of pouches. In some embodiments, a camera (or other sensor) may be positioned upstream of the take-up roll 174 to verify, for example, that the correct number of pharmaceuticals are packaged within each pouch. The spool may correspond to pharmaceuticals requested by a particular patient or a particular facility. In other embodiments, the pouches may be cut and separated as they are filled, rather than spooled onto the take-up roll 174 continuously. 
- In some embodiments, thepackaging units 118 may include equipment for packaging pharmaceuticals in a blister pack or card, rather than a pouch. Alternatively, thepackaging units 118 may include equipment for packaging pharmaceuticals in a pharmacy vial. In such embodiments, the feed stock rolls 166, 170 and the take-up roll 174 may be removed and replaced with other suitable packaging equipment. Furthermore, thepackaging system 110 may include a variety ofdifferent packaging units 118 to package the pharmaceuticals into a combination of pouches, blister cards, and/or pharmacy vials. In some embodiments, pharmaceuticals may be packaged into different types of packaging containers at the same time by using thepackaging units 118 having different types of packaging equipment. 
- In some embodiments, eachpackaging unit 118 may include a printer to print a patient's name, the date, the amount and type of pharmaceuticals contained within, a bar code, and/or other indicia on the pouches as the pouches are formed. The printer may be, for example, a thermal printer. In other embodiments, the printer may include an ink ribbon or an ink jet. In addition, eachpackaging unit 118 may include a bar code scanner or vision system to monitor and check the pouches as they are spooled onto the take-up roll 174 or cut. 
- In some embodiments, thepackaging units 118 may include rollers, castors, or other types of wheels. The wheels allow a user to roll thepackaging units 118 toward and away from thestorage unit 114 in a modular fashion. In the illustrated embodiment, thepackaging units 118 can be easily connected to thestorage unit 114 by aligning themotor bases 134 with designated areas of theframe 126. When theunits 114, 118 are connected, a single control system can communicate with thestorage unit 114 to control operation of thegantry assembly 130 and with thepackaging units 118 to control operation of the packaging equipment. Such an arrangement allows thepackaging units 118 to be quickly exchanged to package pharmaceuticals in different types and/or sizes of pouches or for maintenance. 
- The illustratedpackaging system 110 includes a control system that functions in a similar manner to thecontrol system 50 discussed above. A user can interact with thepackaging system 110 through the control system to input patient information, facility information, and/or the pharmaceuticals needed. The control system can control movement of thegantry assembly 130 to movecanisters 122 from the shelves of thestorage unit 114 to one of the motor bases 134. In addition, the control system can control operation of themotor bases 134 to selectively operate theactive canisters 122A. Furthermore, the control system may optimize orders by minimizing movement of thegantry assembly 130 andcanisters 122 or by filling all the orders for a particular patient or facility consecutively. 
- As shown inFigs. 8 and9, thepackaging system 110 also includes arefill unit 178 coupled to thestorage unit 114. Therefill unit 178 includes aninput port 182 and anoutput port 186. When acanister 122 is empty, thegantry assembly 130 can move thecanister 122 to theoutput port 186. The control system may notify a user that a canister is in theoutput port 186 with an audible noise, email, or other alert. The user can then remove thecanister 122 from theoutput port 186, fill thecanister 122 with suitable pharmaceuticals, and return the filledcanister 122 to the system through theinput port 182. The illustratedinput port 182 includes aninternal scale 190 that weighs the filledcanister 122 to determine how many pharmaceuticals were added to thecanister 122. Thescale 190 may be internal to thepackaging system 110 to inhibit tampering, air flow, and the like from disturbing thecanisters 122 while being weighed In some embodiments, therefill unit 178 may also include bar code scanners that automatically scan thecanister 122 as it is removed from and returned to thesystem 110. Such an arrangement limits the number of canisters being removed from thesystem 110 at a time to reduce the possibility of refilling error. In addition, such an arrangement allows a user to easily access any of thecanisters 122 within thesystem 110 without having to use a ladder or stool to reach the top row of canisters. In some embodiments, thecanisters 122 also include RFID tags which can be read at eachport 182, 186, as well as the filling stations, to help track thecanisters 122 within thepackaging system 110. 
- In other embodiments, a particular area (e.g., a portion of some rows and/or columns) within thestorage unit 114 may be designated as the refill area. In such embodiments, thegantry assembly 130 may moveempty canisters 122 to this area for refilling by a user. When a filled canister is placed in the refill area, a user may interact with the control system to notify thesystem 110 of the location of the filled canister and the type/number of pharmaceuticals contained therein. Thegantry assembly 130 may carry the canister from the refill area to its proper location within thestorage unit 114. 
- In some embodiments, onemotor base 134, onemanifold 138, and onepackaging unit 118 may operate together as a standalone packaging system. Such a system has a relatively small footprint for use in lower volume pharmacies or facilities. In these embodiments, a user may manually place and removecanisters 122 on themotor base 134, as needed, to package pharmaceuticals using thepackaging unit 118. In addition, themotor base 134 may be moved relatively lower and/or divided into multiple rows to facilitate access by a user. 
- Figs. 10-15 illustrate another embodiment of apackaging unit 218 for use with thepackaging system 110. Similar to thepackaging unit 118 discussed above, the illustratedpackaging unit 218 includes amotor base 222, a manifold 226, areceptacle 230, two feed stock rolls 234, 238, and a take-up roll 242. 
- As shown inFigs. 10-12, the manifold 226 includes a plurality ofdiscrete tracks 246 corresponding to each of thecanisters 122 mounted on themotor base 222. The illustrated tracks 246 are independent channels that together form themanifold 226. Thetracks 246 isolate the pharmaceuticals from each other as the pharmaceuticals slide down the manifold to the receptacle. 
- As shown inFigs. 11 and12,cameras 250 are mounted to themotor base 222 adjacent outlets in thebase 222. Eachcamera 250 is associated with one of thecanisters 122 supported on thebase 222. Thecameras 250 are operable to determine whether the proper number and/or type of pharmaceuticals are being dispensed from thecanisters 122. Thecameras 250 capture images of pharmaceuticals exiting themotor base 222 and compare features (e.g., color, contour, size, shape, inscription, etc.) of the pharmaceuticals to stored images of known pharmaceuticals. In some embodiments, recognition software may be employed to automatically compare the images captured by thecameras 250 to stored images. In other embodiments, the captured images may be transmitted to a remotely-located pharmacist or technician who analyzes the images and verifies that the correct number and type of pharmaceuticals were dispensed. In further embodiments, thecameras 250 may be infrared sensors that only detect whether an object (e.g., a pill) drops through themotor base 22, rather than identifying the particular type of pharmaceutical. 
- As shown inFigs. 13-15, thereceptacle 230 receives the pharmaceuticals from each of thetracks 246 in themanifold 226. In the illustrated embodiment, thereceptacle 230 includes a shutter orvalve mechanism 254 that temporarily stops the pharmaceuticals before the pharmaceuticals are collected in a pouch by the feed stock rolls 234, 238. The illustratedshutter mechanism 254 includes a plunger orpushrod 258 that is movable between a first or lowered position (Fig. 14) and a second or raised position (Fig. 15). When in the lowered position, theplunger 258 blocks the pharmaceuticals from traveling out of themanifold 226. When in the raised position, theplunger 258 is moved out of the way to allow the pharmaceuticals to pass toward the packaging equipment (e.g., the feed stock rolls 234, 238). In some embodiments, theshutter mechanism 254 may include a solenoid or other suitable actuator to raise and lower theplunger 258. 
- In operation, theplunger 258 is initially in the lowered position (Fig. 14) to temporarily stop the pharmaceuticals. Theplunger 258 remains in this position until all the requested pharmaceuticals are gathered in thereceptacle 230. If an excess or incorrect pharmaceutical is dispensed from the canisters 122 (which may be determined by the cameras 250), a gust of air, deflector, or trapdoor may be employed to remove that pharmaceutical from thereceptacle 230 or from the manifold 226 before the pharmaceutical reaches thereceptacle 230. In some embodiments, detecting whether an excess or incorrect pharmaceutical may include inspecting a pharmaceutical when the pharmaceutical is in flight (e.g., dropping from themotor base 222 into the manifold 226) as it is released from acanister 122. Thecameras 250 mounted on themotor base 222 may be used to identify each dispensed pharmaceutical, for example, by reading an inscription on the pill. Thecameras 250 may be high-speed camera and may include prisms and/or mirrors to capture an all-around image of a dispensed pharmaceutical. The control system may then process the image captured by the high-speed camera 250 to determine whether a correct or intact pharmaceutical was dispensed from thecanisters 122. Once the proper pharmaceuticals are within thereceptacle 230, theplunger 258 is actuated to the raised position (Fig. 15) such that the pharmaceuticals can be packaged in a pouch. Theplunger 258 is then re-actuated to the lowered position to help push the pharmaceuticals into the pouch and await the next batch of pharmaceuticals. 
- Fig. 16 illustrates apouch 300 containingdifferent pharmaceuticals 304 therein. The illustratedpouch 300 is an example of a pouch that may be formed using the packaging equipment of thepackaging units 18, 118, 218 described above. Thepouch 300 is a clear plastic (e.g., cellophane) bag having three closededges 308 and anopen edge 312. Aheat seal 316 extends across thepouch 300 adjacent theopen edge 312 to seal thepouch 300. In some embodiments, all fouredges 308, 312 of thepouch 300 may be closed via heat seals. Additionally or alternatively, thepouch 300 may be composed of an opaque and/or non-plastic material. For example, one or both sides of the material may be opaque or colored (e.g., amber colored). As discussed above, identification indicia 320 (e.g., a patient's name, a barcode, types of pharmaceuticals, etc.) are printed on thepouch 300 using, for example, a thermal printer, an inkjet printer, a thermal transfer ribbon, or the like. In other embodiments, theidentification indicia 320 may be printed on a label that is coupled to thepouch 300 with adhesives. In further embodiments, thepouch 300 may include a header area and/or a footer area without medication, but that provides space to print or apply theindicia 320. In some embodiments, thepackaging unit 218 may dispense empty (i.e., non-filled) pouches including certain information for a patient. The information may include, for example, instructions on how or when to take the pharmaceuticals, reminders to get new batch of pharmaceuticals, or the like. 
- Referring back toFig. 10, thepackaging unit 218 also includes avisual inspection system 324. The illustratedvisual inspection system 324 is mounted to the packaging equipment, rather than themotor base 222. Thevisual inspection system 324 includes a camera or other suitable sensor. The camera looks at the contents of eachpouch 300 after thepouches 300 are filled. The camera also looks at the indicia 320 (e.g., a barcode) printed on eachpouch 300. Thesystem 324 can then compare the detected pouch contents to the expected pouch contents to verify whether thepouch 300 was filled correctly. This arrangement allows thepackaging unit 218 to inspect thepouches 300 in real time. Thepackaging unit 218 can make corrections, stop operation, and/or notify a user if errors are detected. In the illustrated embodiment, thevisual inspection system 324 is located on one side of the packaging strip. In this arrangement, thevisual inspection system 324 can infer theindicia 320 on thepouch 300 by knowing what was printed and tracking the location of the packaging strip. Alternatively, if thepouch 300 is made of clear material, the camera of thevisual inspection system 324 can look through thepouch 300 to read the indicia. In such embodiments, thevisual inspection system 324 may include a processor with software or firmware that reverses and interprets theindicia 320. In other embodiments, thevisual inspection system 324 may include two cameras located on both sides of the packaging strip (e.g., one camera to verify the contents of thepouch 300, and one camera to read the indicia 320). In further embodiments, a mirror may be mounted to the packaging equipment so that the camera of thevisual inspection system 324 can see around and on both sides of the packaging strip. 
- Thevisual inspection system 324 may be used in conjunction with or independently of thecameras 250 on themotor base 222. As noted above, thecameras 250 view the pharmaceuticals as the pharmaceuticals are released by themotor base 222. Since the pharmaceuticals are released in a controlled manner (e.g., without many other pharmaceuticals around) and thecameras 250 are not looking through other materials (e.g., the plastic packaging of the pouch 300), thecameras 250 can accurately view and determine the inscriptions on the pharmaceuticals (rather than simply relying on shape, color, etc.). Thecameras 250 thereby identify each pharmaceutical as the pharmaceuticals are released into themanifold 226. Thevisual inspection system 324 communicates with thecameras 250 to determine which pharmaceuticals are expected in thepouch 300. Thesystem 324 then verifies that all of the pharmaceuticals reached thepouch 300. 
- Figs. 17 and 18 illustrate a portion of anotherpackaging unit 400 for use with thepackaging system 110. Thepackaging unit 400 is similar to thepackaging unit 218 discussed above. Reference is hereby made to the description of thepackaging unit 218 above for description of features and elements of thepackaging unit 400 not specifically discussed below. 
- In the illustrated embodiment, thepackaging unit 400 includes areceptacle 404 to control pharmaceuticals (e.g., pills P) as the pharmaceuticals are packaged into a pouch (e.g., thepouch 300 shown inFig. 16). Thereceptacle 404 receives pharmaceuticals from one or more tracks (e.g., thetracks 246 of the manifold 226 shown inFig. 10) and directs the pharmaceuticals toward packaging equipment. As explained above, the packaging equipment can include two feed stock rolls and a take-up roll (e.g., therolls 234, 238, 242 shown inFig. 10) to form a pouch. In other embodiments, the packaging equipment can include a single feed stock roll. Thereceptacle 404 is located upstream of the packaging equipment to receive the pharmaceuticals from the track before the pharmaceuticals reach the packaging equipment. 
- The illustratedreceptacle 404 includes acollection area 408 and avalve mechanism 412. Thecollection area 408 communicates with the track to receive pharmaceuticals. Thevalve mechanism 412 blocks the pharmaceuticals before the pharmaceuticals reach the packaging equipment. In the illustrated embodiment, thevalve mechanism 412 includes a plunger orinjector 416. Theplunger 416 is movable relative to the track and thecollection area 408 between a first or lowered position (Fig. 17) and a second or raised position (Fig. 18). When in the lowered position, theplunger 416 blocks the pharmaceuticals from moving out of thecollection area 408 toward the packaging equipment. When in the raised position, theplunger 416 is moved out of the way to allow the pharmaceuticals to pass toward the packaging equipment. In the illustrated embodiment, theplunger 416 slides linearly between the lowered and raised positions. In some embodiments, thevalve mechanism 412 may include a solenoid or other suitable actuator to raise and lower theplunger 416. 
- The illustratedreceptacle 404 also includes aflapper 420. Theflapper 420 is located downstream of thecollection area 408. Theflapper 420 helps managematerial 432 being released by the feed stock rolls of the packaging equipment to form pouches. In particular, theflapper 420 extends into apath 424 between thecollection area 408 and the packaging equipment and engages the material 432 to inhibit the material 432 from being torn or from binding. In addition, theflapper 420 helps hold edges of the material 432 close to each other for sealing. In the illustrated embodiment, theflapper 420 is pivotable relative to thepath 424 about apivot shaft 428. In other embodiments, theflapper 420 may move linearly relative to thepath 424. In some embodiments, theflapper 420 may be biased by, for example, a spring, into thepath 424. 
- In some embodiments, theflapper 420 may also selectively block thepath 424 between thecollection area 408 and the packaging equipment. When theplunger 416 is in the raised position (Fig. 18), the illustratedflapper 420 extends into thepath 424 between thereceptacle 404 and the packaging equipment. In this position, the pharmaceuticals are held above a pouch before the pharmaceuticals are loaded into the pouch. When theplunger 416 is in the lowered position (Fig. 17), theflapper 420 is moved out of thepath 424, allowing theplunger 416 to extend through thepath 424. If a pharmaceutical was being held on theflapper 420 before theplunger 416 moved to the lowered position, the pharmaceutical is also forced by theplunger 416 into the pouch formed by the packaging equipment. When theplunger 416 is moved back to the raised position, the leading edge of theflapper 420 pushes the two halves of the pouch (i.e., the two strips of material 432) flat against each other. 
- In other embodiments, theflapper 420 may include a carve-out or recess along its leading edge. The carve-out may generally match the shape and contour of theplunger 416. The carve-out provides a hole for pharmaceuticals to move into a pouch without being blocked by theflapper 420. In such embodiments, theflapper 420 does not pinch the two sides of the pouch tight against each other along an entire edge, but only pushes the two side edges of the pouch close together so the upper edge of the pouch can be closed. 
- In some embodiments, theplunger 416 is held between the material 432 as the pouch is being formed. More particularly, the pouch is formed by sealing (e.g., heat sealing) the two strips ofmaterial 432 along three edges (e.g., the bottom edge and the two side edges). This sealing process can be performed in a single step using a U-shaped sealing mechanism. Before the two strips ofmaterial 432 are sealed together, theplunger 416 is positioned between the strips ofmaterial 432. The sealing mechanism then creates the seal around theplunger 416. By creating the seal around theplunger 416, the two strips ofmaterial 432 are connected together, but do not lie flat against each other. When theplunger 416 is moved to the raised position (Fig. 18), theplunger 416 moves out from between the two strips ofmaterial 432, and the pouch is left open at the top. As further explained below, theplunger 416 can be moved back to the lowered position (Fig. 17) to help push the pharmaceuticals into the pouch. The two strips ofmaterial 432 can then be advanced so that theplunger 416 is between upstream sections of thematerial 432. When the next pouch is ready to be formed, the U-shaped sealing mechanism can again seal the two strips ofmaterial 432 along three edges. The bottom seal of this pouch becomes the top seal of the previous pouch. A cutting mechanism can then create, at generally the same time and stroke, a line of serrations through the bottom/top seal between pouches to facilitate later separating the pouches. Alternatively, the cutting mechanism can cut apart the pouches at the seal as the pouches are completed. 
- Fig. 19 illustrates part of a series or strip ofpouches 434 created using thepackaging unit 400. Thepouches 434 that are sealed along all four edges with heat seals 435.Serrations 437 are formed in the heat seals 435 between thepouches 434 to facilitate separating thepouches 434. As shown inFig. 19, the pouches can be different lengths to accommodate, for example, different amounts of pharmaceuticals. 
- Referring back toFigs. 17 and 18, in operation, thevalve mechanism 412 physically pushes pharmaceuticals into a pouch to load the pouch, rather than relying on gravity for the pharmaceuticals to fall into the pouch. In particular, theplunger 416 of thevalve mechanism 412 is initially in the lowered position (Fig. 17) as thereceptacle 404 receives pharmaceuticals from the track. While in the lowered position, theplunger 416 blocks pharmaceuticals from traveling to the packaging equipment so that all of the pharmaceuticals are first collected in thecollection area 408. Blocking the pharmaceuticals with thevalve mechanism 412 allows the pharmaceuticals to settle together toward the bottom of thecollection area 408 while the previous pouch is still being sealed. Thevalve mechanism 412 inhibits the pharmaceuticals from going into the wrong pouch. Thevalve mechanism 412, thereby, increases the accuracy and speed of thepackaging unit 400 and provides error prevention. Thevalve mechanism 412 also inhibits the pharmaceuticals from being crushed or damaged in the sealing area of the pouches by the sealing mechanism. Additionally, the pouch is advanced at generally the same speed as thevalve mechanism 412 to inhibit the valve mechanism from damaging the pharmaceuticals or the pouch. 
- During this time, each feed stock roll of the packaging equipment releasesmaterial 432 to form a pouch. The material 432 from each feed stock roll forms half of the pouch. The two halves are secured together along three sides or edges (e.g., the bottom and the two sides) to close the sides and form the pouch. In the illustrated embodiment, the sides of the pouch are closed by, for example, heat sealing. Because the pouches are made on-demand from feed stock rolls, the pouches can be made variable in length (e.g., longer or shorter), as shown inFig. 19, depending on the amount of pharmaceuticals being packaged. For example, pouches are made having lengths between about 1 inch and about 3 ¼ inches, although other lengths of pouches are also possible. The length of the pouch may be determined automatically by the packaging equipment based on the amount of pharmaceuticals expected to be loaded into the pouch, and the area needed to print indicia and other information on the pouch. The amount of material needed to form a particular pouch can be identified on thematerial 432 by an indexing mark (e.g., a black line) drawn on thematerial 432. Once the packaging equipment sees this mark, the feed stock rolls stop releasingmaterial 432. In embodiments where the packaging equipment only includes a single feed stock roll, the material 432 from the single roll may be folded along one side or edge to close the edge. In either embodiment, thematerial 432 may be pre-printed with indicia regarding the pharmaceuticals and patient. After the pouch is initially formed, one of the heat sealing elements is moved away from thematerial 432. This action causes the pouch to open along its upper, unclosed edge. 
- The illustratedplunger 416 also helps form and shape the pouch. When theplunger 416 is in the lowered position, theplunger 416 is located between the two strips ofmaterial 432 that form the pouches. Thematerial 432 can be closed (e.g., heat sealed) along three edges (e.g., the bottom and two sides) to form the initial shape of the pouch. In the illustrated embodiment, theplunger 416 includes a substantially curvedouter surface 436 on one side and a substantially flatouter surface 440 on the opposite side. The curvedouter surface 436 shapes one of the strips ofmaterial 432 in an arch relative to the other strip ofmaterial 432. This arrangement causes the arched strip ofmaterial 432 to not lie flat against the other strip ofmaterial 432, making it easier for pharmaceuticals to fill the pouch. In addition, when theplunger 416 is removed from the pouch, a hole or gap is left between upper edges of thematerial 432, allowing the pharmaceuticals to more easily move into the pouch. 
- In some embodiments, once the pouch is formed around theplunger 416, theplunger 416 moves to the raised position (Fig. 18). The pharmaceuticals are then released from therespective canisters 122. The pharmaceuticals fall through the manifold 226 and into the pouch due to gravity. Theplunger 416 moves to a second position at the top of the pouch where the opening is formed to help push the pharmaceuticals into the pouch. Theplunger 416 then moves to the lowered position (Fig. 17) and thematerial 432 is advanced by the packaging equipment at generally the same speed that theplunger 416 moves. When theplunger 416 is in the lowered position (Fig. 17), the top of the pouch is sealed along with the sides of a new pouch as described below. 
- In other embodiments, once all of the required pharmaceuticals are collected in thecollection area 408 and the pouch is formed, theplunger 416 moves to the raised position (Fig. 18). The pharmaceuticals then fall out of thecollection area 408 toward theflapper 420, which in some embodiments blocks thepath 424 to the packaging equipment. Theplunger 416 then moves back to the lowered position (Fig. 17) to help push the pharmaceuticals into the pouch. Thematerial 432 is advanced by the packaging equipment at generally the same speed that theplunger 416 moves so theplunger 416 does not crush or damage the pharmaceuticals, particularly if the pouch is being filled with many pharmaceuticals (e.g., 15-20 pills, or more). Instead, theplunger 416 pushes the pharmaceuticals to move the pharmaceuticals past and out of the way of the sealing mechanism so the sealing mechanism can make the top seal in the pouch. In some embodiments, theplunger 416 may also actuate a cam-type mechanism that moves theflapper 420 slightly ahead of movement of theplunger 416. By helping push the pharmaceuticals into the pouch with theplunger 416, more pharmaceuticals can be loaded into the pouch more reliably. For example, in some embodiments, theplunger 416 may be used to move 10-40 pharmaceuticals into a single pouch. Such volume of pharmaceutical loading into a pouch may not be attainable by relying on gravity alone. In addition, such an arrangement allows more pharmaceuticals to be loaded into a single pouch than conventional devices, which reduces the possibility of confusing a patient by providing all of the pharmaceuticals in a single pouch (rather than multiple pouches each containing a small number of pills). 
- As the pharmaceuticals are loaded into the pouch by theplunger 416, thematerial 432 is advanced to begin forming the next pouch around theplunger 416. Theflapper 420 is pivoted toward theplunger 416 to help hold edges of the material 432 together. Once thematerial 432 is sufficiently advanced by the feed stock rolls, a fourth side or edge (e.g., the top) of the pouch is closed by the sealing mechanism. Similar to the other sides, the fourth side of the pouch may be closed by, for example, heat sealing. As noted above, the seal forming the fourth (or top) side of the pouch may also form the bottom seal of the next pouch. This process is continued to create a series of discrete pouches, as shown inFig. 19. 
- Thereceptacle 404 of thepackaging unit 400 facilitates loading pharmaceuticals into pouches more accurately, faster, and at a higher capacity than packaging units which rely on gravity feed. As such, the pouches can be filled more reliably. 
- In some embodiments, thepackaging unit 400 may further include a secondary staging area located upstream of thecollection area 408 of thereceptacle 404. The secondary staging area may include a valve mechanism or flapper that temporarily stops pharmaceuticals to create a delay as the pharmaceuticals travel from the track to thereceptacle 404. As such, if thepackaging unit 400 determines (via a sensor or camera) that an improper pharmaceutical was dispensed, the second staging area can remove the unwanted pharmaceutical before the pharmaceutical reaches the collection area. In some embodiments, the secondary staging area may remove the unwanted pharmaceutical by pushing the pharmaceutical away with the valve mechanism. In other embodiments, the secondary staging area may remove the unwanted pharmaceutical with a focused gust of air. If the pharmaceutical is verified as being correct, thevalve mechanism 412 can open to allow the pharmaceutical to pass into thecollection area 408 of thereceptacle 404.
