<p>PROBLEM TO BE SOLVED: To positively feed guard sheets sheet by sheet by lifting the uppermost guard sheet of a guard sheet group by suction pads from above, and conveying the guard sheet in the sucked state to feed it. SOLUTION: Motors 130, 120 and a fixed part 150 are moved so that three suction parts 110 come into a specified position above a guard sheet group 180A, and suction pads 111 of three suction parts 110 are almost horizontally positioned. In the stopped state of the motors 130, 120, the fixed part 150 is lowered downward to bring the suction pads 111 into close contact with the uppermost guard sheet of the guard sheet group 180A to suck it. After sucking the guard sheet, the motor 120 is driven to move only the center suction pad 111 by the specified distance while sucking the guard sheet, and driving of the motor 120 is stopped.</p> |
