Abstract

A dispensing system and associated method provides a turnkey solution for dispensing pharmaceutical products such as solid medications and nutritional supplements to be taken orally in health care settings, including but not limited to long term care (LTC) and assisted living settings.

Claims

1. An automation apparatus for dispensing groups of individually packaged products, the apparatus comprising:

a storage arrangement adapted to store a plurality of products each contained in an individual package, wherein the storage arrangement comprises a first module and a second module, wherein the first module is adapted to store products having a first frequency demand threshold and the second module is adapted to store products having a second frequency demand threshold that is lower than the first frequency demand threshold;

a plurality of fixed first discharge assemblies adapted to move selected ones of the individual packages from the first module of the storage arrangement;

a second discharge assembly comprising a moveable pick device, the second discharge assembly adapted to move selected ones of the individual packages out of the second module of the storage arrangement;

a transfer station adapted to receive and hold the individual packages selected from the second discharge assembly; and

a conveyor having assigned spaces, each assigned space adapted to receive the selected individual packages first from the first discharge assemblies and then from the transfer station.

2. The apparatus of claim 1, further comprising:

a sensor to inspect the individual packages; and

a control device to verify that the individual packages are correct.

3. The apparatus of claim 1, wherein the storage arrangement further comprises:

a plurality of storage tubes in both the first module and in the second module, each tube adapted to contain a plurality of one type of product in individual packages.

4. The apparatus of claim 3, wherein the storage tubes of the first module are arranged in a generally linear array and oriented generally perpendicularly relative to a direction of travel of the conveyor and the storage tubes of the second module are arranged in a two-dimensional array and oriented obliquely relative to the conveyor direction of travel.

5. The apparatus of claim 1, wherein the conveyor further comprises:

a plurality of carriers each fixedly mounted relative to each other and movable along a conveyor path, each carrier being adapted to receive and hold a plurality of the individual packages in a linear arrangement.

6. The apparatus of claim 1, wherein the pick device of the second discharge assembly further comprises at least one gripper movable from a first position for engaging and picking an individual package to at least a second position.

7. The apparatus of claim 6, wherein the pick device of the second discharge assembly further comprises a transfer nest proximate the gripper, the transfer nest including at least one slot for receiving one or more individual packages from the gripper, the transfer nest movable from a first position wherein the individual packages can be received from the gripper, to a second position for delivering the individual packages to the transfer station.

8. The apparatus of claim 1, wherein the transfer station is located between the second discharge assembly and the conveyor.

9. The apparatus of claim 1, wherein the assigned spaces are adapted to receive blister packages.

10. The apparatus of claim 5, wherein the conveyor is adapted to receive blister packages in a linear arrangement.

13. The method of claim 1, wherein the first and second storage modules comprise a plurality of storage tubes, each tube adapted to contain a plurality of one type of product in individual packages.

14. The method of claim 13, wherein the storage tubes of the first module are arranged in a generally linear array and oriented generally perpendicularly relative to a direction of travel of the conveyor and the storage tubes of the second module are arranged in a two-dimensional array and oriented obliquely relative to the conveyor direction of travel.

16. The method of claim 1, wherein the moveable pick device of the second discharge assembly further comprises a transfer nest, the transfer nest movable from a first position wherein the second subset of individual packages can be received after being picked from the second storage module, to a second position for delivering the second subset of individual package to the transfer station.

11. A method of dispensing a selection of individually packaged products, the method comprising:

assigning a designated space on a conveyor for receiving the selection of individually packaged products;

moving the designated space on the conveyor along a conveyor path past a first storage module and a second storage module, wherein the first module is adapted to store products having a first frequency demand threshold and the second module is adapted to store products having a second frequency demand threshold that is lower than the first frequency demand threshold;

moving a first subset of the selection of individually packaged products via one or more fixed first discharge assemblies onto the conveyor at the designated space;

retrieving a second subset of the selection of individually packaged products from the second storage module via a second discharge assembly comprising a moveable pick device;

moving the retrieved second subset of the selection of individually packaged products into a transfer station;

holding the second subset of the selection of individually packaged products at the transfer station; and

moving the retrieved second subset of the selection of individually packaged products onto the conveyor at the designated space.

12. The method of claim 11, further comprising:

inspecting and verifying the individually packaged products during retrieval.

15. The method of claim 11, wherein the conveyor comprises a plurality of carriers each fixedly mounted and movable along a conveyor path, each carrier being adapted to receive and hold a plurality of the individual packages in a linear arrangement.

17. The method of claim 11, wherein the transfer station is located between the second discharge assembly and the conveyor.

18. The method of claim 15, further comprising receiving and holding the selection of individually packaged products in the assigned space and wherein the assigned space is a slot.

19. The method of claim 15, wherein the individually packaged products are each contained in blister packages.

20. The method of claim 11, further comprising receiving and holding the selection of individually packaged products in a linear arrangement in the assigned space.
