Abstract

A pharmaceutical storage and retrieval system and a method of storing and retrieving pharmaceutical containers from the system. The system includes a pharmaceutical storage and retrieval and a controller operatively coupled to the device to control storage and retrieval functions of the device. The device includes a gantry assembly, a shelving assembly, a user access assembly, and a user authorization system that function in a coordinated manner to carry out the storage and retrieval functions of the device.

Claims

1. A pharmaceutical storage and retrieval system comprising:

a housing including a frame;

a shelving assembly supported within the housing, the shelving assembly configured to store containers of pharmaceuticals;

a user access assembly supported by the housing, the user access assembly including a port defined in the housing; and

a gantry assembly supported by the frame and including

a track assembly positioned within the housing,

a carriage assembly supported by the track assembly, the carriage assembly configured to engage the containers to move the containers between the shelving assembly and the port, and

a drive assembly coupled to the track assembly and to the carriage assembly, the drive assembly operable to coordinate movement of the carriage assembly within the housing,

wherein the track assembly includes a first track and a second track arranged perpendicular to the first track, wherein the first track is coupled to the second track to travel along the second track, and wherein the carriage assembly is coupled to the first track to travel along the first track,

wherein the drive assembly includes a first belt circuit coupled to the first track and to the carriage assembly, and a first motor connected to the first belt circuit.

2. The pharmaceutical storage and retrieval system of claim 1, wherein the track assembly further includes a third track parallel to and spaced apart from the second track, wherein the first track is also coupled to the third track to travel along the third track.

3. The pharmaceutical storage and retrieval system of claim 2, wherein the first track is a generally vertical track, the second track is a generally horizontal track, and the third track is a generally horizontal track.

4. The pharmaceutical storage and retrieval system of claim 1, wherein the drive assembly further includes a second belt circuit coupled to the first track and to the carriage assembly, and a second motor connected to the second belt circuit.

5. The pharmaceutical storage and retrieval system of claim 4, wherein rotation of the first and second motors in the same direction causes the carriage assembly to move along the first track, and wherein rotation of the first and second motors in opposite directions causes the first track to move along the second track.

6. The pharmaceutical storage and retrieval system of claim 5, wherein rotation of the first and second motors at different speeds causes the first track to move along the second track and causes the carriage assembly to move along the first track, resulting in diagonal movement of the carriage assembly within the housing.

7. A pharmaceutical storage and retrieval system, comprising:

a housing including a frame;

a shelving assembly supported within the housing, the shelving assembly configured to store containers of pharmaceuticals;

a user access assembly supported by the housing, the user access assembly including a port defined in the housing; and

a gantry assembly supported by the frame and including

a track assembly positioned within the housing,

a carriage assembly supported by the track assembly, the carriage assembly configured to engage the containers to move the containers between the shelving assembly and the port, and

a drive assembly coupled to the track assembly and to the carriage assembly, the drive assembly operable to coordinate movement of the carriage assembly within the housing,

wherein the carriage assembly includes a gripper assembly that is configured to engage a portion of a container,

wherein the carriage assembly further includes a first motor and a second motor coupled to the gripper assembly through a gear assembly, wherein the first motor is operable to rotate the gripper assembly about a first axis, and wherein the second motor is operable to rotate the gripper assembly about a second axis that is parallel to and spaced apart from the first axis.

8. The pharmaceutical storage and retrieval system of claim 7, wherein the first and second motors provide coordinated motion of the gripper assembly about the first and second axes, resulting in linear or near linear movement of the container held by the gripper assembly such that the container may be inserted perpendicularly with respect to the shelving assembly.

9. The pharmaceutical storage and retrieval system of claim 7, wherein the gripper assembly is rotatable through 180 degrees of rotation about the first axis, and wherein the gripper assembly is rotatable through 180 degrees of rotation about the second axis.

10. The pharmaceutical storage and retrieval system of claim 7, wherein the gripper assembly includes a plurality of fingers configured to grasp a cap of the container.

11. The pharmaceutical storage and retrieval system of claim 10, wherein the gripper assembly further includes a motor operable to move the plurality of fingers.

12. The pharmaceutical storage and retrieval system of claim 10, wherein each finger includes an insert providing a sharp and hard surface for engaging the cap of the container.

13. A pharmaceutical storage and retrieval system comprising:

a housing including a frame;

a shelving assembly supported within the housing, the shelving assembly configured to store containers of pharmaceuticals;

a user access assembly supported by the housing, the user access assembly including a port defined in the housing; and

a gantry assembly supported by the frame and including

a track assembly positioned within the housing, the track assembly including a first track and a second track arranged perpendicular to the first track, the first track being coupled to the second track to travel along the second track,

a carriage assembly supported by the first track to travel along the first track, the carriage assembly including a plurality of fingers configured to engage caps of the containers to move the containers between the shelving assembly and the port, and

a drive assembly including a first belt circuit coupled to the first track and to the carriage assembly, a second belt circuit coupled to the first track and to the carriage assembly, a first motor connected to the first belt circuit, and a second motor connected to the second belt circuit, wherein the first and second motors are operable to cause the carriage assembly to move along the first track and to cause the first track to move along the second track.
