US Patent 9481516 Robotic sortation system

A material handling system comprises a main conveyor, a branch conveyor, and a robotic line sorter. The robotic line sorter comprises a robotic arm and an end effector operable to engage an article. The robotic line sorter is operable to perform one or a combination of the functions of orienting, aligning, gapping, and/or moving an article from the main conveyor to the branch conveyor. The material handling system may further comprise a scanner configured to read and communicate information from an article to the robotic line sorter. The robotic line sorter may be configured to deliver an article to the branch conveyor in a predetermined order, until a predetermined condition is met, or based upon a predetermined characteristic.
