PURPOSE:To make it possible to provide a completely automatized jig with no change in working arrangement being required for similar workpieces, by making elevatable two receiving and delivering jigs having a clamp and release means which are opposed to each other arranged along a vertical line, and as well by providing a introducing and discharging robot. CONSTITUTION:In the case of that an empty jig J2 is fitted into an upper jig receiver 49 but no jig is fitted in a lower jig receiver 34, when a conveyor positions a jig J1 attached with a machined workpiece W on a pallette at a receiving and delivering position, a robot member 63 positions a gripper 66 right above the pallette and moves down the same to pull off the jig J1 for making the gripper 66 coaxial with the lower jig receiver 35 to fit the jig J1 into the jig receiver 35. Then, the upper jig receiver 49 is lowered to insert the jig J2 into a hole in the workpiece W to grip the same and to release the confinement of the jig receiver 35, and the upper jig receiver 49 is positioned at the top end. The robot member 63 is positioned at its top position and the gripper 66 is closed to grip the jig J2. Then the robot 63 is positioned at its intermediate position, and the jig J2 is vertically reversed to be fitted in the pallette on the conveyor, thereby automatic receiving and delivering operation is completed. |
