    摘要: Automated tray handling systems and methods may include robotic systems having various end effectors to move trays relative to item sortation systems. For example, the robotic systems may include robotic arms and gantry systems. In addition, the various end effectors may include dual end effectors and passthrough end effectors. The dual end effectors may lift, move, and place trays by engaging and clamping onto flanges of the trays. The passthrough end effectors may lift, move, and place trays through an interior of the end effectors by engaging and pulling or pushing flanges, edges, or other surfaces of the trays. The various automated tray handling systems and methods may increase the speed and efficiency of such processes while also reducing or minimizing the space required for such systems.

    摘要: Systems, methods, and computer-readable media are disclosed for active safety systems for item sortation equipment. In one embodiment, an example system for an item sortation machine may include a first camera configured to image a first exterior portion of the item sortation machine, memory configured to store computer-executable instructions, and at least one processor configured to access the memory and execute the computer-executable instructions to detect a human present at a first location in the first exterior portion, and determine, using the first location, a first portion of an aisle of the item sortation machine to designate a restricted travel zone. Shuttles of the item sortation machine in the restricted travel zone may be prevented from movement. The system may determine that a first shuttle of the item sortation machine is in the restricted travel zone, and may cause the first shuttle to be paused.

    摘要: Systems, methods, and computer-readable media are disclosed for camera-based tracking systems for item sortation systems. In one embodiment, an example method may include determining, by a controller using first image data from a camera configured to image an aisle of an item sortation machine, a first item disposed on a first shuttle at a first location, where the first shuttle is in motion to a first designated drop off location, determining a first shuttle identifier of the first shuttle, and determining the first designated drop off location using the first shuttle identifier. Example methods may include determining that the first item has fallen onto a floor of the aisle, and determining that the first item was not delivered to the first designated drop off location.

    摘要: Systems, methods, and computer-readable media are disclosed for container location flaps with increased degrees of freedom for sortation systems. In one embodiment, an example rotatable flap for use with an item sortation machine may include a first portion having a first frame and a first mesh grid coupled to the first frame, a second portion having a second frame and a second mesh grid coupled to the second frame, and a first coupler configured to couple the second portion to the first portion. The second portion may be configured to rotate from a first position coplanar to the first portion to a second position transverse to the first portion, and the first portion may be coupled to a frame of the item sortation machine and configured to rotate with respect to the frame.
