Apparatus and methods for automated dispensing of medications and supplements
A system for assembling and dispensing an order made up of one or more individually packaged items from a plurality of different individually packaged items includes a storage module containing one or more packages of each of the items, and a conveyor having selectively assignable spaces configured to receive the packaged items associated with a particular order and to transport the packaged items to a processing location. A pick device is movable relative to the storage module and is configured to retrieve a package from the storage module. A transfer station adjacent the conveyor receives one or more of the packaged items from the pick device and an actuator associated with the transfer station moves the packaged items from the transfer station to the conveyor when the assigned space associated with the order is in registration with the transfer station.
1. A system for assembling and dispensing an order comprising a selection of individually packaged items selected from a plurality of different individually packaged items, the system comprising:
a storage module containing the plurality of different individually packaged items;
a conveyor comprising assigned spaces configured to receive the selection of individually packaged items associated with the order and adapted to transport the selection of individually packaged items;
a pick device movable vertically and horizontally to access said storage module and configured to retrieve individually packaged items from said storage module;
a transfer receptacle associated with the pick device and configured to receive individually packaged items from the pick device when the transfer receptacle is in a first orientation adjacent to the pick device and wherein the transfer receptacle is configured to rotate away from the pick device to a second orientation while maintaining positive physical control of the individually packaged items;
a transfer module for receiving the individually packaged items from the transfer receptacle when the transfer receptacle is in the second position while maintaining positive physical control of the individually packaged items; and
an actuator associated with said transfer module and operative to move the selection of individually packaged items from said transfer module to said conveyor when one of said assigned spaces associated with the order is in registration with said transfer module.
2. The system of claim 1 , further comprising a sensor provided proximate to the pick device to verify that the picked individually packaged items are requested items.
3. The system of claim 1 , wherein said pick device comprises:
a rotatable housing; and
at least one gripper operatively coupled to the housing and movable from a first position for engaging and picking an individually packaged item from said storage module, to at least a second position for transferring the individually packaged item to said transfer receptacle when said transfer receptacle is in said first orientation.
4. The system of claim 1 , wherein the transfer receptacle comprises at least one slot shaped complementary to the shape of the individually packaged items such that the individually packaged items received on the transfer receptacle are constrained to allow movement only along a longitudinal axis of said at least one slot.
5. The system of claim 1 , wherein the transfer module comprises at least one channel shaped complementary to the shape of the individually packaged items such that the individually packaged items received on the transfer module are constrained for movement only along a longitudinal axis of said at least one channel.
6. The system of claim 1 , wherein the conveyor is configured to positively control movement of the individually packaged items received on the conveyor.
7. The system of claim 6 , wherein the conveyor comprises a plurality of channels, each channel shaped complementary to the shape of the individually packaged items such that the individually packaged items received on the conveyor are constrained for movement only along longitudinal axes of the respective channels.
8. The system of claim 7 , wherein the assigned spaces of the conveyor comprise one or more of the conveyor channels.
9. The system of claim 1 , wherein the storage module further comprises:
a first and a second module each located proximate the conveyor;
wherein the first module is adapted to store products having a first frequency demand and the second module is adapted to store products having a second frequency demand different from the first frequency demand.
10. The system of claim 1 , wherein the conveyor and the transfer module are configured to receive a plurality of selections of individually packaged items.
11. A method of filling an order that includes a selection of individually packaged items selected from a plurality of different individually packaged items, the method comprising:
assigning dedicated space on a conveyor for receiving the selection of individually packaged items for the order;
for each individually packaged item in the selection of individually packaged items:
picking an individually packaged item for the order from a storage module via a pick device movable vertically and horizontally to access the storage module;
placing the individually packaged item in a transfer receptacle directly from the pick device such that positive physical control of the individually packaged item is maintained;
rotating the transfer receptacle away from the pick device and moving the individually packaged item from the transfer receptacle to a transfer module, such that positive physical control of the individually packaged item is maintained;
moving the selection of individually packaged items from the transfer module to the dedicated space when the dedicated space is in registration with the transfer module; and
moving the conveyor to a processing location.
12. The method of claim 11 , wherein the transfer receptacle is moved into registration with the transfer module prior to moving the selection of individually packaged items from the transfer receptacle to the transfer module.
13. The method of claim 11 , further comprising verifying that the picked individually packaged item is a requested item during moving the individually packaged item to the transfer module.
