This disclosure relates generally to robotic labeling of medicament containers.
Many medications in a pharmacy are supplied from the manufacture in a ready to use container. After a doctor writes a prescription the pharmacy fulfills the prescription for the patient. Typical prescription containers in the US pharmacy market are removed from a storage location by a pharmacy technician and a label is applied to the container by the technician. The containers come in many shapes and sizes, which makes automated labeling difficult without extensive programing of a robot or other mechanical complexities. For example, a pharmacy may supply prescriptions in pill bottles, liquid medicine bottles, blister packs, boxes, etc. Each of these containers may come in different sizes depending on the amount of pills or volume of liquid medicament distributed. Further, these containers may be made of any numbers of materials (such as glass or plastic) with varying thicknesses.
Existing systems are complex and require extensive programming to handle the multitude of types and sizes of containers used in a pharmacy. Current automation in the field uses complex methods to get a label attached to a container. One method used is to place the container into a carrier that moves the container to a second location where the container is transferred to a labeling mechanism. This labeling mechanism then must locate the product for labeling and in the case of a cylindrical container must rotate the container to wrap the label around package. An alternate method used is to use a robot to pick the container and then to program multiple robot-moves to identify the container and wrap the label around the container.
The complexity and need of programming limit the use of these machines in the marketplace. Pharmacy containers change in a facility frequently due to supply chain and competitive forces. Complex changeover to add and subtract products from a machine limit the machine's potential uses and usefulness in a pharmacy.
Simplified systems, methods, and apparatuses are needed to streamline this cantankerous process.
The present disclosure contains new and innovative systems, methods, and apparatuses to simplify the process of labeling medicament containers by using a pick point to retrieve the container and a labeling position that is not container-specific. This automatically performs the functions of fulfilling a prescription for a patient at a pharmacy after a doctor writes a prescription. The picking and labeling are agnostic to the type of container being labeled. The systems and methods enable picking and labeling the container on at least one shared axis. The systems and methods ensure reliable label placement and easy container implementation. The present disclosure reduces mechanical and programming complexity by picking and labeling about a common axis—greatly simplifying the automation and improving the reliability of the process. The result of the process is a labeled medicament container.
One advantage of the systems and methods herein is that the two actions of picking and labeling are both done around the same center axis to insure a balanced, self-centering of the container picking and labeling. Another advantage is that the systems and methods allow many different containers to be simply picked and labeled automatically without human intervention. It should be appreciated that the systems, methods, and apparatuses herein are not limited to labeling medicament containers, but can be used on any system which places labels onto goods.
In light of the disclosure set forth herein, and without limiting the disclosure in any way, in a first aspect, which may be combined with any other aspect described herein, or portion thereof, a system includes a picking device that grabs at least one container and moves it to a labeling device that attaches the label onto the at least one container. The invention does this by matching the center of the picking location with the center of the labeling location and applying the label with a tamper head that complies to the label surface on each side of the center of the at least one container.

Additional features and advantages of the disclosed system, method, and apparatus are described in, and are apparent from, the following Detailed Description and the Figures.
The accompanying drawings, which are incorporated in and constitute a part of this specification, show certain aspects of the subject matter disclosed herein and, together with the description, help explain some of the principles associated with the disclosed implementations.
Referring now to the drawings and in particular to
The medicament container system 100 accomplishes this preferably through the use of a processor 150 operatively coupled to the medicament container system 100. The processor 150 may comprise a programmable logic controller (“PLC”). The processor 150 may specify what medicament container 108 to pick and what label to put on that medicament container 108. This information may be based on a prescription request sent to the processor 150 from a pharmacist or from an outside source through software loaded onto the processor 150. The processor 150 may confirm that the correct medicament container 108 is being labeled by processing an image from a camera 180 operatively coupled to the processor 150. The camera 180 may alternatively be a bar code scanner or QR code reader. The processor 150 may also confirm that the medicament container 108 has been labeled correctly by processing an image from the camera 180. Multiple cameras 180, bar code scanners, or QR code readers can be employed, separately or in combination, in order to gain a desired amount of verification and verification steps. In some embodiments, an image from the camera may be used to gather image data, bar code data, and QR code data. The processor 150 may employ commercially available software, proprietary software, and/or artificial intelligence software in order to perform the processing of the images from the camera 180.
The feeder 104 may be passive in moving the medicament container 108 in that a medicament container 108 may be placed on a sloped surface of the feeder 104 which funnels to the picking location or a medicament container 108 could be placed on a flat surface of the feeder 104 with a spring configured to move the medicament container 108 transversely along the flat surface of the feeder 104, which may be preferable in instances where multiple medicament containers 108 corresponding to the same type of medicament are loaded in a row along the surface. Alternatively, the feeder 104 may actively move the medicament container 108 by means of a coil like that of a vending machine, a conveyer belt with or without vertical flaps to keep the medicament container 108 upright, a piston, or any other sufficient means of actively moving the medicament container 108. The feeder 104 may have a plurality of shelves. In one embodiment, the feeder 104 has four shelves 105a-d, each with a plurality of rows 107 which may contain at least one medicament container 108. The shelves 105a-d may be modular in that the width of the rows 107 can be adjusted depending on the size of the medicament container 108 that will reside in that row 107. The width may be adjustable by moving a row separator 109. A ruler may be affixed to each shelf 105a-d such that the width of each row 107 can be easily seen. The ruler may aid in determining the location of each medicament container 108 for the actuator 102. In one embodiment, a human operator preprograms the processor 150 with the width of each row 107 and a height of the medicament container 108 in each row 107. In another embodiment, a camera, communicatively coupled to the processor 150, is configured to capture an image of the ruler and the processor 150 is configured to read the ruler at the outer bounds of the width of the medicament container 108 or at the row separators 109 bounding the width of the medicament container 108. In any embodiment, further data that may be collected for storage at the processor 150 or memory may include the height, width, depth, diameter(s), cap diameter, cap height, or any other pertinent information about the medicament containers 108. In this manner the actuator 102 can consistently pick the medicament container 108 in any given row 107 at a consistent location on the medicament container 108. The medicament containers 108 may be fed into the feeder 104 by a conveyor system, by a human operator, by another machine, or in any other appropriate manner.
The medicament container 108 may have at least one circular portion, which may be disposed on a top portion of the medicament container 108. The medicament container 108 may be any number of shapes and/or sizes depending on such factors as the preference of the manufacturer, the amount of medicament in a single medicament container 108, whether the medicament is a liquid or solid, whether the medicament is in a pill form, or any other number of factors. The medicament container system 100 of the present disclosure is configured to operate consistently no matter the size and/or shape of the medicament container 108 and may be agnostic as to the size and/or shape of the medicament container 108. Having at least one circular portion on the top portion of the medicament container 108 simplifies the steps of the medicament container system 100 by allowing a more consistent reference point for the medicament container system 100. However, it should be noted that this is a preferred embodiment and not meant to limit the present disclosure to the employment of medicament containers 108 with a circular portion or where the circular portion is disposed on the top portion of the medicament container 108. The medicament container 108 may be of any type supplied, such as in a box or a blister pack.
At an appropriate time, the actuator 102 moves the pick head 106 into a position in which the pick head 106 can operatively contact a desired medicament container 108. The pick head 106 may be configured to grab a medicament container 108 using at least one grabbing surface such as a ring-shaped surface configured to fit around a top of the medicament container 108. Any number of grabbing mechanisms could be employed by the pick head 106 alone or in combination, such as a series of two or more finger-tip-like structures configured to grab an edge of the medicament container 108 or around a top of the medicament container 108, two or more plates that contact opposing sides of a medicament container 108 (such as in the embodiment illustrated in
The processor 150 may be configured to direct the actuator 102 to move to a different row 107, for example, if the primary row of that type of medicament container 108 is empty or to distribute more evenly which rows 107 are drawn from to maintain a first-in-first-out process or any other logical process, possibly including randomization.
The actuator 102 is then configured to move the pick head 106 with the operatively coupled medicament container 108 to a labeler 110. The labeler 110 comprises a tamp head 118 with a tamp head axis B. The tamp head axis B may be substantially parallel to the pick head axis A such that the medicament container 108 is in a substantially similar position after being moved by the actuator 102 as when it was residing in the feeder 104 at the picking location. In one embodiment, each of the medicament containers 108 has a circular portion disposed on a top portion of the medicament container 108 and each medicament container 108 is placed in relation to the tamp head axis B such that the circular portion of each medicament container 108 is concentric when moved to the labeler 110.
Turning now to
This may be accomplished by placing the label 220 between a set of rotatable blocks and/or rollers which manipulate the position of the label. Alternatively, a single rotatable block or roller may be used in conjunction with a stationary surface. For example, in
In this manner the adhesive will contact the medicament container 308 before any other part of the label 320 and ensure that the label 320 is correctly oriented for the duration of the labeling operation. Alternatively, an adhesive could be applied to the medicament container 308 corresponding to at least a portion of an area where the label 320 is to be applied. The label 320, optionally without adhesive in this alternative embodiment, may still be folded such that greater control is exercised over the orientation of the label 320 relative to the medicament container 308 during the labeling operation. In such an embodiment, the label 320 may be in a continuous spool 330 with perforations to separate the label 320 from others on the spool 330. The spool 330 can be fed much the same way as in the embodiment of
Returning to the embodiment of
The tamp head 218 may comprise a flexible material that conforms to the shape of the medicament container 208 when pressure is applied between the tamp head 218 and the medicament container 208. Alternatively, the tamp head 218 may comprise a rigid material. In such an embodiment, the tamp head 218 may be moved along a perimeter of the medicament container 208 without exceeding a threshold force measurement by the at least one tamper actuator 212. This may be done by rolling or gliding the tamp head 218. Alternatively, the actuator 102 may be configured to move the medicament container 208 in relation to a label that is held in place by the tamp head 218. In any above embodiment, pressure is applied to generally the whole area encompassed by the interface of the medicament container 208 and the label where adhesive is present. The tamp head 218 may be adapted to be as flexible or rigid as desired. Alternatively, the tamp head 218 may comprise a mechanism which applies air pressure to the interface of the label and the medicament container 208. In this manner even pressure may be achieved over the desired area between the label and the medicament container.
The labeling operation is preferably configured to run with each medicament container 208, no matter the size or shape, oriented relative to the tamp head axis B. Because each medicament container 208 is oriented relative to tamp head axis B and pressure measurement is taken to ensure the medicament container 208 does not change position such that the labeling operation can no longer work or the medicament container 208 breaks, the system 100 of
Returning to
Machine reading technology may be added to the medicament container system 100 to verify accuracy of the process during or between sequence steps. A typical process may be as follows: (1) verify that the medicament container 108 going into the feeder 104 is the correct medicament container 108 for that shelf 105a-d and row 107 by processing an image from camera 180; (2) after picking the medicament container 108 move to a verification point and verify the correct container is in the pick head 106; (3) move medicament container 108 to label position; (4) verify correct label is printed; (5) place label on medicament container 108; (6) verify label is correct and properly affixed to medicament container 108 by processing an image from camera 180; (7) place labeled medicament container 108 in order tote 160. These verification steps or any combination or subcombination thereof may be used depending on the desired level of verification.
The desired verification steps and the information relevant to them may be stored on the processor 150 or the memory 170. Verification may be accomplished by a camera 180, communicatively coupled to the processor 150, configured to capture an image of the ruler and the processor 150 being configured to read the pertinent information from the captured image and compare that information to a set of verification information. Alternatively, at least one barcode scanner in communicative operation with the processor 150 may be employed alongside or in place of the camera to gather the relevant information. Any number or combination of cameras and scanners may be employed to ensure proper verification of the medicament container 108 and/or label.
