ABSTRACT:
A conveyor system having first second and third stations and a return conveyor in communication with and linking the first and third stations: The first station has a device to selectively feed pallets, one at a time, from the return conveyor to a position underneath an unpackaged work piece disposed on the first station portion of the conveyor system and help position the pallet with the work piece on top of it on to another part of the first station portion of the conveyor system, which conveys the pallet and the work piece to the second station where packaging of the workpiece is carried out, for example, shrinking a plastic sheet about the work piece. Another part of the conveyor system conveys the packaged work piece to the third station where a device removes the pallet from the packaged work piece, places the packaged work piece on another part of the third station portion of the conveyor and places the pallet on the return conveyor for return to the first station.
