Abstract

Abstract A manufacturing system having one or more loading and unloading stations and a plurality of spaced apart numerically controlled machine tools, the operation of which is effected by direct computer control. The manufacturing system includes a workpiece supply system comprising a closed loop trackway on which one or more cars are supported for guided movement to the various stations. The car carries a pallet on which a work holding fixture with a workpiece is secured, and transports the pallet to a computer selected machine station. At the selected station the pallet is automatically removed from the car and placed on a multiple positionable table which serves as a workpiece receiving and storage device from which a desired next workpiece to be supplied to the machine tool is automatically selected and transferred thereto by computer control. The computer automatically directs an empty car to the unloading side of the machine tool to receive a pallet with a workpiece that a work operation has been performed on and then by computer direction returns to the unload station where the pallet is removed or the car will be directed to advance the workpiece to a different machine tool.
