PURPOSE:To improve working efficiency by starting movement of a gripping means at the timing before an upper die arrives at a top dead point and operating a press machine at the timing before the gripping means returns to the home position. CONSTITUTION:When a die is selected by a die selecting switch 7 according to the kind of the die, a storage means 4 is called out. When the device is operated, a gripping means 3 moves toward a press machine on the left side then moves toward the right and returns to the home position after placing the work gripped by a gripper 3a on a lower die 2b on the right side. A CPU 9 commands starting of the press machine when it is confirmed by a position detector 5 for the gripping position that the gripper 3a arrives at a non-interfering positon. The upper dies 1a, 2b ascend after the press machine presses the work and the ascending distance thereof is measured by a position detector 6 for the upper dies. When the dies arrive at a non-interfering position, a command is emitted from the CPU 9 to operate the means 3. |
