ABSTRACT:
A transfer has gripper bars capable of grasping, lifting and transferring a work piece. The grasping and lifting motions are actuated by face cams. The face cams act through rocker arm linkages connected to rotatable rods having arms connected to the gripper bars. The transferring motion is actuated by a barrel cam having an axial cam curve positioned between cam followers. A lifting frame has diagonal slots which receive guide pins connected to a base frame. A rack and pinion assembly connected to the gripper bars facilitates the gripping motion. Slidably mounted blocks with toothed wheels supporting arms of various radial extension provide variable travel distances for the gripper bar when moving in the transfer direction.
