  • Patent number: 11772906
    Abstract: A control system for an automated singulation system is provided. The control system detects a presence of a first item on a first conveyor and detects a presence of a second item on a second conveyor while the first item is present on the first conveyor. The second conveyor transfers items onto the first conveyor and is at a lower height than the second conveyor. The first conveyor is oriented perpendicularly with respect to the second conveyor. In response to detecting the presence of the second item, a location of the first item along a length of the first conveyor is determined. The first conveyor and the second conveyor are controlled based at least on the location of the first item.

  • Patent number: 10807808
    Abstract: Systems and methods to separate and present items for picking and movement to various downstream systems may include an item separation system, a vision system, and an item picking system controlled or instructed by a control system. The control system may instruct an item separation system comprising a plurality of conveyors at various positions, orientations, or heights to separate and present items at a picking area. The vision system may capture imaging data of items at the picking area. The control system may identify items or pickable surfaces. The control system may further instruct an item picking system to pick and move items from the picking area to various downstream systems and/or may instruct the item separation system to change aspects of movement of items to further separate and present items at the picking area.
