Title: BILATERAL SORTER
Abstract:
A system for sorting objects includes an upstream and a downstream conveyor positioned to sequentially receive and convey an object along a first path, and a sorting conveyor belt positioned transversely in a gap between the upstream and downstream conveyors. The sorting conveyor is tilted with respect to the plane of the other conveyors, and carries flexible projections that lift one edge of the object and push it. The operation of the sorting belt reduces static friction between the object and the main conveyors as the object is pushed. The system also includes a measuring device operatively linked to provide dimensions and position information about the object to a sorting conveyors controller.
