Robotic system having shuttle
A robotic system includes a robot having a picking arm to grasp an inventory item and a shuttle. The shuttle includes a platform adapted to receive the inventory item from the picking arm of the robot. The platform is moveable between a pick-up location located substantially adjacent to the robot and an end location spaced a distance apart from the pick-up location. The system improves efficiency as transportation of the item from the pick-up location to the end location is divided between the robot and the shuttle.
1. A robotic system for sorting items, comprising:
a put wall having cubbies; and
a shuttle including:
a track extending along a first side of the put wall in a first horizontal direction;
a carriage moveable along the track;
a vertical post extending from the carriage; and
a platform moveable along the vertical post and relative to the carriage such that the platform is arranged to receive an item at a pick-up location and deposit the item into a select one of the cubbies.
2. The system of claim 1 , wherein cubbies are arranged in a first horizontal row and a second horizontal row stacked on top of the first horizontal row.
3. The system of claim 1 , further comprising a scanner for identifying the item and/or determining the select one of the cubbies.
4. The system of claim 1 , wherein the platform includes a dispenser to displace the item from the platform in a second horizontal direction and deposit the item into the select one of the cubbies, the second horizontal direction being substantially orthogonal to the first horizontal direction.
5. The system of claim 4 , wherein the dispenser includes a cross-belt or a push tray.
6. The system of claim 1 , wherein the select one of the cubbies has a ledge provided at a second side of the put wall opposite of the first side of the put wall and a bottom angled toward a ground surface from the first side of the put wall toward the second side of the put wall such that when the item is deposited into the select one of the cubbies the item will slide along the bottom toward the ledge.
7. The system of claim 6 , wherein the select one of the cubbies defines an interior space for temporarily storing the item and the interior space is accessible from the first and second sides of the put wall.
8. A robotic system for sorting items, comprising:
containers defining an open top, the containers being arranged in a first horizontal row and a second horizontal row; and
a shuttle including:
a track extending in a first horizontal direction;
a carriage translatable along the track; and
a platform coupled to the carriage and translatable relative to the carriage in a second horizontal direction transverse to the first horizontal direction, the platform being arranged to receive an item at a pick-up location, carry the item to a select one of the containers, and deposit the item into the select one of the containers.
9. The system of claim 8 , wherein the track includes a set of parallel tracks and the carriage extends between the set of parallel tracks such that the platform is elevated above the first and second horizontal rows of containers.
10. The system of claim 8 , wherein the second horizontal direction is orthogonal to the first horizontal direction.
11. The system of claim 8 , wherein at least part of the platform is pivotable from a transport position arranged to support the item to a delivery position arranged to deposit the item into the select one of the containers.
12. The system of claim 8 , further comprising a robot located adjacent to the pick-up location, the robot including a picking arm arranged to pick the item from a picking location and place the item on the platform.
13. A method of sorting items, comprising:
picking a first item to singulate the first item;
placing the singulated first item on a shuttle, the shuttle including a track, a carriage moveable along the track, and a platform;
moving the carriage along the track in a first direction and moving the platform relative to the carriage in a second direction transverse to the first direction; and
actuating at least a portion of the platform in a third direction to deposit the singulated first item into a first sorting location after the moving step.
14. The method of claim 13 , further comprising scanning the first item to determine the first sorting location from other sorting locations.
15. The method of claim 13 , wherein the picking step is performed by a warehouse worker or a robot with a picking arm.
16. The method of claim 13 , further comprising:
picking a second item to singulate the second item;
placing the singulated second item on the platform;
moving the carriage along the track in the first direction and moving the platform relative to the carriage in the second direction; and
actuating the at least a portion of the platform in the third direction to deposit the singulated second item into a second sorting location.
17. The method of claim 16 , wherein the first sorting location corresponds to a first order and the second sorting location corresponds to a second order different than the first order.
18. The method of claim 16 , further comprising batch picking inventory including the first item and the second item from a storage location and transporting the inventory to a picking location.
19. The method of claim 18 , wherein the transporting step is performed at least in part by a conveyer.
