ABSTRACT:
An apparatus for loading or unloading a workpiece to be pressed by a press machine. The equipment has cam grooves for a work motion and a return motion, on which a pin is mounted to contact with the biasing force of a cylinder device. The pin is further engaged with an intermediate portion of a maim arm which constitutes a parallel link mechanism in association with a slider link, a sub arm and a carriage link mounting a workpiece holder thereon. The slider link, on which the upper end of the main arm is secured, upwardly and downwardly moves with the guidance of a guide member. As separate cam grooves are provided for the work motion and the return motion, the workpiece holder can move in an appropriate route. This enables the continuous operation of the press machine.
