US Patent 10226794 Dynamic tray spacing

A controller of a material handling system performs a method of dynamic spacing on a sortation conveyor by predicting fullness of divert destinations. Required tray spacing between inducted articles destined for the same divert destination can be reduced when the divert destination is calculated to have sufficient capacity. Fewer discharge commands need to be ignored due to insufficient tray spacing. The material handling systems can achieve higher throughput by having fewer articles that cannot be discharged to an assigned destination.
