PURPOSE:To control the operation of jigs without using any control circuit, by preparing an operation member for controlling the operation of a working member and operating the operation member with a robot when the robot returns from the working position. CONSTITUTION:When the welding of both A and B works is completed and a welding gun 1a is retreated to a lateral side, an operation valve 9 is operated by the gun 1a. A cylinder is actuated by the fluid supplied through the valve 9 to the cylinder, by which an inversion bar is turned to invert both combined work W. When the work W is inverted to a prescribed position, the gun 1a is detached from the valve 9 and welds both B and C works. The operation after the retreat of the robot can be thus applied without using any intricate electrical control circuit to be controlled by the signal from a robot control device. |
