ABSTRACT:
A transfer system for moving workpieces between a plurality of processing stations in sequential order. A pair of guide rails extend in a workpiece transferring direction on opposed sides of the stations and are movable up and down by a driving mechanism. A plurality of arm carriages are movable along the guide rails and are joined to one another by longitudinally extending connecting bars. A plurality of handling arms extend laterally between opposed pairs of the carriages. All of the arm carriages are moved as a group by a carriage driving mechanism. Auxiliary guide rails can be fixed to the carriages extending in parallel with the main guide rails. The handling arms can be movable longitudinally along the auxiliary guide rails. Rack and pinion mechanisms can be mounted on the arm carriages and the handling arms and interconnected with each other so as to drive each pair of arms in opposite directions.
