Abstract

A production line which includes a shuttle conveyor extending between two work stations. A first transfer device for transferring a workpiece from one of the work stations to the conveyor and a second transfer device for transferring the workpiece to the second work station are equipped with workpiece gripping or supporting devices which may be rapidly changed when the line is shifted from the production of one form of workpiece to the production of another workpiece having a different configuration. Replacement workpiece gripping devices are supported adjacent the shuttle conveyor upon holding pedestals. Upon line changeover, the transfer devices locate their workpiece gripping devices upon empty holding pedestals and actuating devices on the pedestal release the gripping devices from their transfer devices. The empty transfer devices are then shifted and coupled to new workpiece gripping devices supported on other holding pedestals. The transfer device includes the ability for adjustment of the article engaging devices in three directions.
