Abstract
A workpiece transfer device has a carrier which travels on rails between a pick-up station and a delivery station. A pair of parallel tracks extends between the two stations. A workpiece gripper has a roller thereon engaged with one track to retain the work gripper in work-gripping position when the carrier is travelling from the pick-up station to the delivery station. The roller engages the other track to retain the work gripper in the release position when travelling in the opposite direction. At the opposite ends of the two tracks cylinder-operated blocks are arranged to receive the roller from one track and shift it to engage the other track.
