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.
Supplements such as dietary supplements (for example, multi-vitamins, minerals, and the like) are generally purchased over the counter at pharmacies and grocery stores. These supplements are purchased in bulk containers and taken according to the instructions on the containers.
Typically consumers are not prescribed supplements. Rather, consumers purchase supplements on their own accord based on personal needs. More recently, consumers are turning to online supplement stores to purchase these supplements. Online stores can provide personal recommendations to consumers based on lifestyle information received from the consumers. Purchasing bulk containers makes it difficult for consumers to adhere to the recommendations. Most consumers store bulk containers at home. Due to various obligations, for example, work, school, and the like, consumers may not be home to take the supplement at the recommended time. Carrying around bulk containers or separating supplements into smaller containers may not be always feasible.
Accordingly, there is a need for high-volume and high-efficiency automatic packaging of supplements into separable packages. These packages allow consumers to take the packages with them wherever they go and results in better adherence to recommendations. Systems and method described below are directed to automatic packagers that package supplements into strip packages or blister cards.

Typically, a single LED device may be used below the platform 320 to illuminate the translucent platform 320. However, the single LED device may not provide uniform lighting through all of the surface area of the platform 320. Particularly, each LED device includes a light signature such that the center of the platform 320 is brighter than the edges of the platform. This irregularity in brightness may result in misidentifying supplements during the image recognition process. In order to provide uniform brightness across the surface are of the platform, several LED devices may be placed around the bottom surface of the platform. In some embodiments, the light signature of the LED device is detected and a backing (not shown) may be applied to the platform to correct the light signature of the LED device. The backing, when applied to the platforms 320, distributes the light from the LED device of the LED lighting system 322 such that every portion of the platform 320 is illuminated with similar brightness.
The shuttle 325 may be moved laterally between the platform 320, over the reservoir 170, and over a conduit 335. The shuttle 325 transfers the supplements from the platform 320 either to the reservoir 170 or to the conduit 335. The shuttle 325 is driven by the shuttle drive 330. The shuttle drive 330 may be a motor assembly, an actuator, or the like that moves the shuttle 325 between the platform 320, over the reservoir 170, and over the conduit 335. In the example illustrated, the shuttle drive 330 includes a rotating screw 332 that moves the shuttle 325 laterally between the platform 320, the reservoir 170, and the conduit 335.

The funnel extension 175 includes a throttle 265 at the opening in the second portion 205. In some embodiments, the throttle 265 includes a supplement opening that is sized to allow a limited number of supplements to pass through at a time. In some embodiments, the throttle 265 is a rotating plate and an actuation mechanism is used to rotate the throttle 265 to transfer the supplements from the funnel extension 175 to the reservoir 170. By limiting the number of supplements passing to the reservoir, the throttle 265 (and thereby the funnel extension 175) prevents overcrowding in the cartridge 155. The throttle 265 may come in different sizes to accommodate different types of supplements. The throttle 265 and/or the funnel extension 175 may be changed for each type of supplement. In some embodiments, the throttle 265 may include different sized supplement openings such that the throttle 265 may be rotated such that only one supplement opening is exposed to allow supplements to pass through. The throttle 265 may be rotated prior to placing the cartridge 155 in the universal feed cassette 105 to select the correct supplement opening corresponding to the supplement being dispensed from the cartridge 155.
In some embodiments, the throttle 265 includes a plate pivotably attached to the opening in the funnel extension 175 using a hinge or other mechanism. The throttle 265 can be pivoted to a fully closed position in which the opening in the funnel extension 175 is fully closed and prevents supplements from going through to the reservoir 170. The throttle 265 can be moved from the fully closed position inward into the funnel extension 175 or outward into the reservoir 170 to provide different size of openings for the supplements to flow through to the reservoir 170.

The motor assembly 310 includes a motor 350 that drives a shaft 355 positioned in the middle of the cartridge mechanism 160. The shaft 355 includes teeth 356 that interlock with the teeth 210 of the wheel 180 (see
The PCB 315 includes the electrical components of the cartridge mechanism 160. The PCB 315 is positioned on the side opposite that of the wheel 180. In some embodiments, the PCB 315 includes an antenna 360 (see
The lockout mechanism 316 is, for example, a lockout solenoid that prevents a cartridge 155 from being loaded onto the cartridge mechanism 160 when the lockout mechanism 316 is activated. During a dispensing process, not all cartridge mechanisms 160 may be used to fill a package. In these situations, the lockout mechanism 316 is used to prevent cartridges 155 from being placed on inactive cartridge mechanism 160. In addition, the lockout mechanism 316 may be used to prevent an incompatible or wrong cartridge 155 from being loaded to the cartridge mechanism 160. For example, the cartridge mechanism 160 may read the RFID tag 365 to determine whether the correct and compatible cartridge 155 is being loaded to the cartridge mechanism 160. The cartridge mechanism 160 may only deactivate the lockout mechanism 316 when the correct cartridge 155 is being loaded to the cartridge mechanism 160. The lockout mechanism 316 may also be used to prevent the cartridge 155 from being removed from the cartridge mechanism 160. Particularly, the lockout mechanism 316 locks the cartridge 155 in place when loaded on to the cartridge mechanism 160. During the dispensing process, the lockout mechanism 316 is activated to prevent removal of the cartridge 155. The lockout mechanism 316 may be deactivated when the dispensing process is complete and the cartridge 155 can be removed from the cartridge mechanism 160.
In some embodiments, the electronic processor 370 is implemented as a microprocessor with separate memory, such as the memory 375. In other embodiments, the electronic processor 370 may be implemented as a microcontroller (with memory 375 on the same chip). In other embodiments, the electronic processor 370 may be implemented using multiple processors. In addition, the electronic processor 370 may be implemented partially or entirely as, for example, a field-programmable gate array (FPGA), an applications specific integrated circuit (ASIC), and the like, and the memory 375 may not be needed or be modified accordingly. In the example illustrated, the memory 375 includes non-transitory, computer-readable memory that stores instructions that are received and executed by the electronic processor 370 to carry out the functionality of the cartridge 155 described herein. The memory 375 may include, for example, a program storage area and a data storage area. The program storage area and the data storage area may include combinations of different types of memory, such as read-only memory and random-access memory.
The transceiver 380 enables wired or wireless communication between the electronic processor 370 and a control system of the automatic packager 100 and/or a control system of the packaging unit 110. In some embodiments, the transceiver 380 may include separate transmitting and receiving components, for example, a transmitter and a receiver.
The other components of the universal feed cassette 105 are described singularly with respect to a single cartridge mechanism 160. However, it should be noted that the descriptions and functionality are equally applicable for each cartridge mechanism 160 of the universal feed cassette 105. The camera system 305 receives control signals from the electronic processor 370. Based on the control signals received from the electronic processor 370, the camera system 305 controls the camera 340 and the lighting system that illuminates the platform 320. The motor assembly 310 may send position sensor signals to the electronic processor 370 and receive control signals to operate a motor of the motor assembly 310 based on the position sensor signals. As described above, the shuttle drive 330 may be a motor assembly or an actuator. The shuttle drive 330 may also include a position sensor to determine the position of the shuttle 325. The shuttle drive 330 may send the position sensor signals to the electronic processor 370, which sends control signals to the shuttle drive 330 to move the shuttle 325 based on the position sensor signals. In some embodiments, the shuttle system 300 may also include a shuttle home sensor, which indicates whether the shuttle 325 is at a home position. Signals from the shuttle home sensor are provided to the electronic processor 370 to control the movement of the shuttle 325.
The pill sensor 362 communicates with the electronic processor 370 to provide an indication of whether or not a pill is dispensed through the conduit 335. The electronic processor 370 also controls the indicator system 364 to provide an indication of the status of each cartridge 155. The indicator system 384 may include one or more LEDs provided behind a translucent plastic material. The electronic processor 370 may use the indicator system 384 to provide indications, for example, whether a cartridge 155 is correctly placed in the cartridge slot 130. The electronic processor 370 may activate, for example, a blue LED to indicate that a next cartridge 155 should be placed in the corresponding cartridge slot 130 (that is, the cartridge slot 130 corresponding to the cartridge mechanism 160 with the blue LED activated). The electronic processor 370 may activate, for example, a green LED to indicate that the cartridge 155 was correctly placed in the cartridge slot 130. The electronic processor 370 may activate, for example, a red LED to indicate that the cartridge 155 was not correctly placed in the cartridge slot 130. Additionally, the electronic processor 370 may use the indicator system 384 to provide indications on where to place a cartridge 155 and when to remove a cartridge 155. For example, the electronic processor 370 may activate a blue LED to indicate that a user can place a cartridge 155 in the cartridge slot 130 corresponding to the activated LED. The electronic processor 370 may activate a blue LED again to indicate that the dispensing process is complete and the cartridge 155 can be removed from the cartridge slot 130.
The method 385 also includes advancing, using the cam and follower mechanism 230, the holding pin 225 into the scooping member 185 (at block 395). Referring to
The method 385 further includes holding the supplement between the holding pin 225 and the stopper 220 (at block 400). When the holding pin 225 is advanced, a supplement is held between the holding pin 225, the circumferential end of the scooping member 185, and the stopper 220. The supplement is held in such a way until the scooping member 185 moves past the top portion of the wheel 180.
The method 385 also includes rotating, using the motor assembly 310, the scooping member 185 past the top portion of the wheel 180 (at block 405). As discussed above, the motor assembly 310 rotates the wheel 180 to rotate the scooping members 185. The motor assembly 310 may also include a position sensor (not shown) to detect a position of the wheel 180. For example, the motor assembly 310 may include a Hall sensor to detect magnets placed at certain locations on the wheel 180 to determine the position of the wheel 180. In other embodiments, the position sensor may be an optical sensor or the like.
The method 385 further includes retracting, using the cam and follower mechanism 230, the holding pin 225 to drop the supplement on to the platform 320 (or for example, a verification system that verifies that an expected supplement (e.g., correct, single, and unbroken supplement) is delivered) (at block 410). Referring to
The method 415 further includes determining whether only a single unbroken supplement is delivered to the shuttle system 300 (at block 425). This may also be referred to as singulation verification. The electronic processor 370 controls the camera system 305 to acquire an image of contents of the platform 320. The mirror 345 reflects the contents of platform 320 to the camera 340, which captures the image. The camera 340 provides the captured image to the electronic processor 370 for verification. The electronic processor 370 may use image recognition techniques on the captured image to ensure that only a single unbroken supplement is delivered to the shuttle system 300. Example image recognition techniques are described in U.S. Patent Application Publication No. 2018/0091745, the entire contents of which are hereby incorporated by reference.
When the electronic processor 370 determines that more than one supplement has been delivered to the shuttle system 300 or that a broken supplement has been delivered to the shuttle system 300, the method 415 includes returning the contents of the shuttle system 300 to the reservoir 170 (at block 430). The electronic processor 370 controls the shuttle drive 330 to move the shuttle 325 from the platform 320 to a first opening (e.g., the first position). The shuttle 325 returns the contents from the platform 320 to the reservoir 170 through the first opening. The method 415 returns to block 420 to deliver the next supplement to the shuttle system 300.
When the electronic processor 370 determines that only one unbroken supplement has been delivered to the shuttle system 300, the method 415 includes determining whether the correct supplement is delivered to the shuttle system 300 (at block 435). As described above, the electronic processor 370 may use the above incorporated image recognition techniques to determine whether the correct type of supplement has been delivered to the shuttle system 300.
When the electronic processor 370 determines that the incorrect type of supplement is delivered to the shuttle system 300, the method 415 moves to block 430 to return the contents of the shuttle system 300 to the reservoir 170, as described above. Accordingly, in blocks 410 and 420, the method 415 is determining whether an expected supplement is delivered to the shuttle system 300. In some embodiments, determining whether an expected supplement is delivered may include only one of the blocks 425 or 435 or the blocks 425 and 435 may be performed in a different order. In other embodiments, rather than checking for whether a single unbroken supplement is delivered to the shuttle system 300, determining whether an expected supplement may include determining whether a correct type of supplement is delivered to the shuttle system 300 regardless of the number of supplements delivered to the shuttle system 300. In yet other embodiments, determining whether an expected supplement may include determining whether a correct number of supplements is delivered to the shuttle system 300.
When the electronic processor 370 determines that the correct type of supplements is delivered to the shuttle system 300, the method 415 includes delivering the supplement to the packaging unit 110 (at block 440). The electronic processor 370 controls the shuttle drive 330 to move the shuttle 325 from the platform 320 to a second opening (e.g., the second position). The shuttle 325 delivers the supplement from the platform 320 to the packaging unit 110 through the second opening, the conduit 335, and the dispensing opening.
The method 415 also includes verifying the delivery of the supplement to the packaging unit 110 (at block 445). The pill sensor 362 detects whether or not a pill was dispensed through the conduit 335 and provides indicating signals to the electronic processor 370. The pill sensor 362 may detect a supplement in any form (e.g., capsule, tablet, gummy, and the like). When the electronic processor 370 determines that a supplement was delivered to the packaging unit 110, the method 415 returns to block 420 to deliver the next supplement. When the electronic processor 370 determines that a supplement was not delivered to the packaging unit 110, the electronic processor 370 sends an interrupt to the control system of the automatic packager 100 and returns to block 420 to re-deliver the supplement.
An example cartridge 155 and cartridge mechanism 160 are described in U.S. Pat. No. 10,583,941 filed on Oct. 15, 2018 and granted on Mar. 10, 2020, entitled “UNIVERSAL FEED MECHANISM FOR AUTOMATIC PACKAGER,” the entire contents of which are hereby incorporated by reference.
The receptacle 510 collects the supplements from the chute 140. After the supplements pass through to the receptacle 510, the supplements are sandwiched between two strips of material (e.g., plastic, paper, etc.) from the feed stock rolls 520, 530. The first feed roll 520 may be made of a first material that is white in color (e.g., a translucent material). The second feed roll 530 may be made of a second material that is clear (e.g., a transparent material) to allow a user to look through the pouch to see the supplements inside the pouch. The two strips of material are then heat sealed together to form a pouch for the supplements. In some embodiments, the strip packager 500 may include a single feed stock roll having a single strip of material that is folded and/or heat sealed to form pouches. Once filled and sealed, the pouches are wrapped around the take-up roll to create a single spool of pouches in the spooling unit 115. The spool may correspond to supplements requested by a particular consumer 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 continuously. The pouches are dispensed through, for example, a dispenser or dispensing port.
In some embodiments, the strip packager 500 may include a printer 560 to print a consumer's name, the date, the amount and type of supplements contained within, a barcode, and/or other indicia on the pouches as the pouches are formed. The printer 560 may be, for example, a thermal printer. In other embodiments, the printer 560 may include an ink ribbon or an ink jet. In addition, the strip packager 500 may include a verification system 540 to monitor and check the pouches as they are spooled onto the take-up roll or dispensed.
In the example illustrated, the automatic packager 100 includes a packager electronic processor 570, a packager memory 580, a packager transceiver 590, a packager input/output interface 600, the motors 610, the cameras 620, the printer 560, and the verification system 540. The packager electronic processor 570, the packager memory 580, the packager transceiver 590, the packager input/output interface 600, the motors 610, the cameras 620, the printer 560, and the verification system 540 communicate over one or more control and/or data buses (e.g., a communication bus 630).
The packager electronic processor 570 and the packager memory 580 may be implemented similar to the electronic processor 370 and the memory 375 respectively, as described above. The packager transceiver 590 enables communication from the automatic packager 100 to the communication network 640. In other embodiments, the packager transceiver 590 may include separate transmitting and receiving components, for example, a transmitter and a receiver. The automatic packager 100, through the communication network 640, may communicate with the universal feed cassette 105.
As noted above, the automatic packager 100 may include the packager input/output interface 600 (or more commonly referred to as a user interface). The packager input/output interface 600 may include one or more input mechanisms (e.g., a touch screen, a keypad, a button, a knob, and the like), one or more output mechanisms (e.g., a display, a printer, a speaker, and the like), or a combination thereof. The packager input/output interface 600 receives input from the input devices actuated by a user, and provides output to the output devices with which a user interacts. In some embodiments, as an alternative or in addition to managing inputs and outputs through the packager input/output interface 600, the automatic packager 100 may receive user inputs, provide user outputs, or both by communicating with an external device, such as a console computer, over a wired or wireless connection.
One advantage of the cartridges 155 is that the cartridges 155 significantly reduce the packaging time compared to prior cartridges. Some prior cartridges had to be manually filled one supplement at a time by a user. In contrast, the user may simply dump supplements from a bulk container into the cartridge 155 and place the cartridge 155 in the universal feed cassette 105. The automatic packager 100 then retrieves supplements from the cartridge 155. The user may then use the funnel extension 175 to keep replenishing the cartridges 155 as the supplements are being packaged without having to remove the cartridges 155 from the universal feed cassette 105 and without having to introduce a delay in the process for refilling.
In the example illustrated in
The automatic packager 100 may be deployed in a high-volume supplement packaging facility. The supplement packaging facility has a plurality of automatic packagers 100 (for example, 10-30 packagers) provided on a packaging floor. The packaging floor also includes large containers that store supplements. Supplements may be fed to the large containers using an automated mechanism. Packaging technicians on the packaging floor may use jugs or other portable containers to pick up supplements from the large containers and top up the cartridges 155. Specifically, in one example, the user refills a gallon jug using the large containers and walks by the automatic packagers 100 to refill the cartridges 155 as needed.
The method 650 includes obtaining a refilling container with next supplement (at block 660). During a first instance, a packaging technician uses a refilling jug to obtain a first supplement from a large container including the first supplement. The refilling container is used by the packaging technician to transport the supplements from the large container to the automatic packagers 100.
The method 650 further includes determining one or more automatic packagers 100 desired to be refilled of the plurality of automatic packagers 100 (at block 665). As the packaging technician moves through the packaging floor, the packaging technician inspects each automatic packager 100 to determine whether the obtained supplement is desired to be refilled for that automatic packager 100. Specifically, the packaging technician visually inspects the funnel extension 175 of the cartridge 155 containing the obtained supplement to determine whether the cartridge 155 is to be refilled. As discussed above, the funnel extension 175 may be made of clear plastic material such that the packaging technician may quickly visually inspect the level of supplements in the cartridge 155 without having to remove the cartridge 155 from the automatic packager 100. In some embodiments, the cartridge 155 in the same relative location of each automatic packager 100 (e.g., “cartridge #3”) may include the same supplement so the packaging technician can simply inspect the cartridge 155 at that location in each automatic packager 100.
The method 650 includes refilling the one or more automatic packagers (at block 670). Upon determining that an automatic packager 100 of the plurality of automatic packagers 100 are desired to be refilled, the packaging technician may top off the corresponding cartridges 155 of the one or more automatic packagers using the refilling container. The packaging technician may refill the cartridges 155 up to a level indicated on the funnel extension 175 of the cartridge 155.
The method 650 proceeds to block 660 to repeat blocks 660, 665, 670 for each supplement being packaged by the plurality of automatic packagers 100. For example, if the automatic packagers 100 are each packaging 40 different supplements, the packaging technician may repeat this process 40 times. In addition, in some embodiments, multiple packaging technicians may be performing this process simultaneously. In such situations, each technician may be responsible for certain supplements and/or cartridges (e.g., a first technician may be responsible for monitoring and refilling cartridge #1 through cartridge #20, while a second technician may be responsible for monitoring and refilling cartridge #21 through cartridge #40). In some scenarios, the packaging technician(s) may know particular supplements are used (e.g., packaged) more often than others and may repeat the process more frequently for those cartridges than for other cartridges.
