Abstract:
A method of carrying-out a product punched out by a punch press machine, comprising:punching out a plate material to manufacture a punched product;moving a slider, said slider including a lift arm vertically movably supported by first and second cylinders and further having a plurality of vacuum pads, from a punched product support position to a punched product carry-out position near the punch press machine;providing product manufacturing data of punched products to provide a basis of such product manufacturing data;calculating a gravity center of the punched product on the basis of the product manufacturing data;recognizing a shape of the punched product on the basis of the product manufacturing data to provide a basis of the recognized shape of the punched product;moving the punched product in both X- and Y-axis directions by an X- and Y-axis locating mechanism of the punch press machine, so that the gravity center of the punched product is located just under at least one of the vacuum pads arranged on a bottom surface of the lift arm;discriminating which vacuum pads are located over the punched product on the basis of the recognized shape of the punched product;actuating the first and second actuation cylinders to lower the lift arm so that vacuum pads are brought into contact with an upper surface of the punched product;actuating the first and second actuation cylinders to move the lift arm upward away from the plate material; andmoving the slider away from the punched product carry-out position to the punched product support position.
