Abstract

Automated dispensing systems and mechanisms for queuing output from an automated dispensing system are provided for the dispensing of articles. The automated dispensing system may increase efficiency of the automated dispensing system by reducing cycle time, increasing throughput, and reducing the time required for the unloading process. A system for dispensing articles may include a carousel including a plurality of stations, a plurality of carrier holders, each configured to be received at a respective station, and a robot configured to retrieve a carrier holder from the carousel. The robot may further be configured to move the carrier holder proximate the location of a first article, load the first article onto the carrier holder, and return the carrier holder to a station of the carousel.

Claims

1. A system for dispensing articles, comprising:

a carousel comprising a plurality of stations;

a plurality of carrier holders, each configured to be received at a respective station; and

a robot configured to retrieve a carrier holder from the carousel, move the carrier holder proximate a location of a first article, load the first article onto the carrier holder, and return the carrier holder to a station of the carousel;

wherein the robot is further configured to;

retrieve the first article from a first location to a carrier of the carrier holder;

retrieve a second article from a second location to a carrier of the carrier holder;

move the carrier holder including the first article and the second article to a position proximate the carousel;

transfer the first article from the carrier of the first article to one of a plurality of carriers configured for receiving articles; and

transfer the second article from the carrier of the second article to another of the plurality carriers configured for receiving articles.

2. The system of claim 1, wherein each of the plurality of carrier holders comprises a plurality of carriers, wherein each carrier is configured to receive one or more articles.

3. The system of claim 2, wherein the articles comprise medications and each of the plurality of carriers is assigned to a patient.

4. The system of claim 3, wherein each of the plurality of carriers is assigned to a time of day for said patient.

5. The system of claim 3, wherein each of the plurality of carriers is configured to receive a patient identifier.

6. The system of claim 5, wherein the patient identifier identifying the patient is loaded onto each respective carrier.

7. The system of claim 6, wherein articles loaded onto each respective carrier are dispensed to a container, and wherein the patient identifier is dispensed to the container for identifying the patient to which the container is assigned.

8. The system of claim 2, wherein the robot is configured to load at least two of the plurality of carriers with the first article.

9. The system of claim 1, further comprising an unload station, wherein the carousel is configured to rotate a station into alignment with the unload station for manual unloading of the carrier holder at the unload station.

10. The system of claim 9, wherein the unload station comprises a plurality of doors and wherein each of said doors is configured to align with, and provide access to, a respective carrier of the carrier holder at the station.

11. The system of claim 1, further comprising an unload station arranged proximate the carousel, wherein the unload station comprises a door for each of the respective plurality of carriers configured for receiving articles, and wherein the carousel rotates to align each respective carrier holder with the unload station.

12. The system of claim 1, further comprising a controller configured to receive an order for the first article, wherein the controller is configured to direct the robot to the location of the first article.

13. A system for dispensing articles comprising:

a carousel comprising a plurality of stations;

a plurality of carrier holders, each carrier holder configured to be received at a respective station of the carousel;

a controller configured to receive an order for a first article and a second article; and

a robot configured to retrieve a carrier holder from the carousel, move the carrier holder proximate a location of the first article, load the first article onto the carrier holder, move the carrier holder proximate a location of the second article, load the second article onto the carrier holder, and return the carrier holder to a station of the carousel.

14. The system of claim 13, wherein the controller is configured to receive a plurality of orders, and wherein the controller is configured to group together orders for a particular patient for loading to a single carrier holder.

15. The system of claim 13, wherein each of the plurality of carrier holders comprises a plurality of carriers, wherein each carrier is configured to receive one or more articles.

16. The system of claim 15, wherein the articles comprise medications and each of the plurality of carriers is assigned to a patient.

17. The system of claim 16, wherein each of the plurality of carriers is assigned to a time of day for said patient.

18. The system of claim 16, wherein each of the plurality of carriers is configured to receive a patient identifier.

19. The system of claim 13, further comprising an unload station, wherein the carousel is configured to rotate a station into alignment with the unload station for manual unloading of the carrier holder at the unload station.

20. The system of claim 19, wherein the unload station comprises a plurality of doors and wherein each of said doors is configured to align with, and provide access to, a respective carrier of the carrier holder at the station.
