ヘッドＡ、Ｂが上昇位置に達して終了される。When a tool change command is output from the control device, the pneumatic cylinder 9 in the Y-axis direction is first activated, and the piston rod acts in the retracting direction, so that the distance between the spindle heads A and B, which are in use, is the minimum distance, that is, TQ Holder 28...'s arrangement Pino Sen is quickly swallowed by one throw. When this operation is confirmed, the Z-axis napo motor in the direction of the third guide rail (not shown) and the Y-axis servo motor in the direction of the second guide rail are controlled.
The spindle heads A and B reach the rising end of the two axes by being driven wholesale, and the spindle heads A and B reach the Y-axis tool position, that is, the return position, which was marked by the use of the previous process.
B is located. When this operation is completed, the pneumatic cylinder 49 is activated, and the plunger body 45 moves from the tool surrounding position to the lower front retracted position, and the cutting tool TI + T2
are exposed at the lower ends of spindle heads A and H, respectively. When this operation is confirmed, the pneumatic cylinder 53, which is the conveyance means for the tool magazine M, is activated, and the tool rack 50 in the standby position (work position) is moved to the tool exchange position (1st position l1t). Among them, the U position is set to the U position in the spindle of the spindle heads A and B. Therefore, in this state, the Z-axis is controlled and driven to lower the spindle spatula l"t~, 13. This lowering 1 drive is continued until the removal position just before the mounting tool T+ + T2 reaches the support plate 59+59 of the empty DI. When this disengagement position is reached, the pneumatic cylinder 4 is actuated and the tightening nut 31 of the chuck means is driven out of rotation, and then the pneumatic cylinder 4 is activated.
4 is activated, the motor 39 is linked to the spindle IL/23 via the rotation operating means, and the spindle IL'23 is rotated in the direction in which the tightening nut 31 is loosened. As a result, the tool holder 28 is pushed downward and the tool holder 28! Due to the pressure, the tool holder 28 is detached from the tapered hole 29 due to its own weight and is stored in the return position on the support plate 59. This installation tool T1. The return of T2 is completed when the spindle heads A and B reach the raised position.

Ｔ４は当初の使用間隔に設定されるものである。B descends, cutting tools T1. Tool holder 28.28 with T4 attached is inserted. This Z-axis drive continues until the leather is below the tool release position and ends. When the tool holder 28.28 is inserted, the motor 39 of the rotation operating means is rotated in the opposite direction to the loosening direction. This will pull up the tightening nut 31, and W4 will be 3
The tool holder 28 is reliably chucked by the 00 action. When this tool chunking is confirmed, the spindle heads A and B are raised by the Z axis, and then the tightening nut 31 is
Removal of the engaging protrusion 35 from the spindle 23, separation of the rotation operating means from the spindle 23, and movement of the brush body 45 to a position surrounding the cutting tool.
