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.

Abstract: An automated system for singulating items is provided. The automated system includes a singulation apparatus. The singulation apparatus includes multiple conveyor modules and a vertical frame structure. Each of the multiple conveyor modules has an identical physical structure. The vertical frame structure provides multiple horizontal mounting locations, each at a different height along the vertical frame structure. Each of the conveyor modules is mounted to a different one of the multiple horizontal mounting locations.

Abstract: An apparatus for unloading tote contents is provided. The apparatus includes an arm assembly, a door assembly connected to the arm assembly, and first and second drivers configured to rotate the arm assembly and the door assembly about first and second axes, respectively. The arm assembly is configured to pick up a tote from a first conveyor belt. The door assembly is configured to secure at least one item within the tote and provide a ramp for unloading the at least one item from the tote onto a second conveyor belt.

Abstract: Singulation system may utilize various features to singulate items, e.g., which may be different sizes from one another. For example, a conveyor may advance items along the length of the conveyor, and paddles arranged for protruding over respective portions of the conveyor may be selectively positionable based on conditions (such as a size or a jammed state) of items detected as present on a relevant part of the conveyor. Additionally or alternatively, a first conveyor may advance items at a first speed and in a first direction to sequentially drop the items onto a second conveyor positioned below the first conveyor, and the second conveyor may advance the received items at a second speed higher than the first speed and in a second direction different from the first direction, e.g., to increase space between items.
