A workpiece presentment system and associated method for workpiece
presentment with a pick and place device is provided. The system includes
a pair of parallel stationary rails, and first and second shuttle rails
respectively disposed adjacent first and second ends ofthe stationary
rails. Each shuttle rail is independently moveable laterally to a
longitudinal alignment with a selected one of the pair of stationary
rails. A control circuit is configured to circulate only two pallets
simultaneously in the same rectangular path of travel to load trays to
the pallets on one of the stationary rails while presenting the trays to
the pick and place device on the other stationary rail.
