PURPOSE:To enable the machining to be performed without an operator so as to decrease a work time and reduce labor, by forming a device so that only the supply of a workpiece onto a rotary stocker and its machining instruction may discriminate a kind of workpiece and select a tightening metal fitting and a pallet. CONSTITUTION:A workpiece is loaded in a stage on each rotary stocker 4A- 4H, and if the stocker 4A is moved to the clamping position of a work hand 33 and stopped by inputting the machining information by a machining instruction device, the hand 33 lowers to stop in the uppermost work position and clamp the workpiece, and a motor 32 is stopped by confirming the clamping. Next, the hand 33, after it rises to stop if a conveying device 6 turns to stop on a relocating device 8A, lowers to place the workpiece on a pallet 9A. On the other hand, if the relocating device 8A is turned, also the pallet 9A is turned to stop by moving a pin 58 also in a hole 59 to be adapted to a part of the workpiece, causing the workpiece to be released from its clamping. Next, the device 8a is turned to an instruction position, clamping a tightening metal fitting corresponding to the workpiece by a chuck and turning to supply the fitting to be fixed onto the workpiece. |
