ABSTRACT:
A slider of the punch carry out unit is moved in the X-axis direction adjacent a punching section of the punch press machine before or after a plate material is punched into a punched product by a punch press machine. At the same time, a gravity center and a shape of the punched product are calculated and recognized on the basis of the manufacturing data. On the basis of the obtained gravity center and the shape of the punched product, the gravity center of the punched product is moved under the lift arm by the X- and Y-axis locating mechanism. Vacuum pads located just over the punched product are selected or discriminated. Then, the lift arm is lowered and the punched product is held by actuating only the discriminated vacuum pads. During this lift motion, it is preferable to bend one end of the punched product slightly upward to easily separate the punched product from the remaining flat plate material. After the punched product has been lifted, the punched product is moved horizontally away from the punch press, and is then lowered on the punched product supporting unit by releasing only the actuated vacuum pads. Since only the vicinity of the gravity center of the punched product is held by a minimum possible number of the vacuum pads, irrespective of the size and shape of the punched products, the number of the vacuum pads can be reduced.
