Abstract

A goods to operator workstation is attachable to an input and a discharge conveyor system. The goods to operator workstation comprises a container staging platform that receives a product container from the input conveyor system and linearly moves the product container to an order pick position for an operator to pick articles from. A holding platform is pivotally movable between the order pick position and a discharge position to discharge a picked order container onto the discharge conveyor system after picking. Wherein when the holding platform moves back to the order pick position, the holding platform passes through the staging platform to transfer the order container from the staging platform to the holding platform so that the staging platform can retract and receive a new order container from the input conveyor system while the operator is picking.

First claim

What is claimed is:

1. A goods to operator workstation for receiving an unpicked product container from an input conveyor system, moving the unpicked product container and items contained therein to an order picking position for operator picking, and after picking, discharging a picked product container onto a discharge conveyor system, the goods to operator workstation comprising:
a workstation structure;
a container staging platform attached to the workstation structure by a linear actuator and linearly movable from a retracted position adjacent to an end of the input conveyor system to receive unpicked product containers therefrom to an extended order picking position adjacent to the operator for operator picking from the unpicked product container; and
a holding platform pivotally attached to the workstation structure pivotally movable back and forth between the order picking position for operator picking from the unpicked product container and a discharge position to discharge the picked product container onto the discharge conveyor system for removal,
wherein the holding platform comprises a fingered structure comprising a plurality of spaced apart fingers with each finger comprising a strip belt operatively connected to one end by a drive roller, wherein the holding platform pivots about a shaft of the drive roller, and
wherein the container staging platform and the holding platform are configured to linearly and rotatably pass through each other without colliding when transferring the unpicked product container from the container staging platform to the holding platform at the order picking position.

2. The goods to operator workstation of claim 1 wherein when the unpicked product container is transferred from the container staging platform to the holding platform, the holding platform is higher than the container staging platform.

3. The goods to operator workstation of claim 1 further comprising a lift mechanism operably connecting between the workstation structure and the holding platform to pivotally move the holding platform back and forth between the order picking position and the discharge position.

4. The goods to operator workstation of claim 3 wherein the lift mechanism comprises at least one extendable and retractable cylinder.

5. The goods to operator workstation of claim 1 wherein the plurality of spaced apart fingers extends as a “U” shape.

6. The goods to operator workstation of claim 5 wherein each of the “U” shaped spaced apart fingers comprises the strip belt exposed at a top of the “U” shape operatively supported at one end by the drive roller and at another end by an idler pulley.

7. The goods to operator workstation of claim 1 wherein the linear actuator linearly movably attaching the container staging platform to the workstation structure comprises a lead screw.

8. The goods to operator workstation of claim 1 wherein the linear actuator linearly movably attaching the container staging platform to the workstation structure comprises a fluidic actuator.

9. The goods to operator workstation of claim 1 wherein the linear actuator linearly movably attaching the container staging platform to the workstation structure comprises an electric actuator.

10. The goods to operator workstation of claim 1 wherein the linear actuator linearly movably attaching the container staging platform to the workstation structure comprises a linkage.

11. The goods to operator workstation of claim 1 wherein the linear actuator linearly movably attaching the container staging platform to the workstation structure comprises a gear train.

12. The goods to operator workstation of claim 1 wherein the linear actuator linearly movably attaching the container staging platform to the workstation structure comprises a belt drive.

13. The goods to operator workstation of claim 1 wherein the container staging platform comprises a motor driven strip belt on each finger to support and move product containers thereon.

14. The goods to operator workstation of claim 2 wherein the container staging platform comprises fingers comprising a solid cantilever member.

15. A goods to operator workstation for receiving an unpicked product container from an input conveyor system, moving the unpicked product container and items contained therein to an order picking position for operator picking, and after picking, discharging a picked product container onto a discharge conveyor system, the goods to operator workstation comprising:
a workstation structure;
a container staging platform attached to the workstation structure by a linear actuator and linearly movable from a retracted position adjacent to an end of the input conveyor system to receive unpicked product containers therefrom, and linearly movable to an extended order picking position for order picking; and
a holding platform pivotally attached to the workstation structure, pivotally movable with a lift mechanism thereof back and forth between the order picking position for operator picking and a discharge position to discharge the picked product container onto the discharge conveyor system for removal,
wherein the container staging platform and the holding platform comprise fingered structures having gaps between fingers and the container staging platform, wherein when the holding platform pivotally moves to the order picking position and the container staging platform is at the order picking position, the holding platform and the container staging platform interleave together without touching when the holding platform moves through the gaps of the container staging platform, and wherein each finger comprises a strip belt operatively connected to one end by a drive roller, wherein the holding platform pivots about a shaft of the drive roller.

16. The goods to operator workstation of claim 15 wherein the holding platform comprises a motor driven strip belt on each finger to support and move product containers thereon.

17. The goods to operator workstation of claim 15 wherein the container staging platform comprises a motor driven strip belt on each finger to support and move product containers thereon.

18. The goods to operator workstation of claim 15 wherein the fingers of the fingered structures of the container staging platform and the holding platform comprise a solid member.

19. The goods to operator workstation of claim 15 wherein the fingers of the fingered structures of the container staging platform and the holding platform comprise cantilevers.
