Referring to the operation of the present invention configured as described above are as follows.

When the tool provided in the tool port 13-1 of the first tool magazine 10-1 is to be replaced, the tool is clamped and picked up by the drive of the tool pick-up means 14, and the tool turning means 15 When it is transmitted to the tool boy 15a, the tool boy cylinder 15b is driven to rotate toward the machine body, as in the prior art.

However, when a signal for picking up a specific tool on the side of the second tool magazine 10-2 is applied, first, the side plate 12-2 of the second tool magazine 10-2 is driven to drive the sprocket 11-2. By moving, the tool of the desired tool port 13-2 is stopped at a position perpendicular to the second sub change means 50.

When the transfer cylinder 31 is driven by the control flow at the same time or in succession, the feed slider 33 in the state of the empty tool feed port 34 reaches the standby position for tool transfer on the guide bar 20. .

Subsequently, while the vertical cylinder 52 and the horizontal cylinder 56 of the second sub change means 50 are driven by a constant control flow, the tool of the tool port 13-2 as the tool gripper 57 is driven by the tool transfer port 57. Transfer to (34).

The operation control flow thereof is such that the vertical cylinder 52 is stopped when the sensing dog 54a at the end of the positioning bar 54 reaches the vertical position detecting switch 55b. (Gripping the tool)

Subsequently, the horizontal cylinder 56 is driven, and the gripper bracket 57a stops by reaching the horizontal position detecting switch 58b. (A state in which the gripped tool is picked up)

Then, as the vertical cylinder 52 is driven again, the sensing dog 54a stops at the position 55b to 55c of the vertical position sensing switch (the state before the picked-up tool is inserted into the tool feed port).

Subsequently, the horizontal cylinder 56 is driven again, and the gripper bracket 57a stops by reaching the horizontal position detection switch 58a. (The tool is inserted into the tool feed port.)

When the tool is transported by such an operation control flow, the vertical cylinder 52 is finally driven to reach the initial state where the detection dog 54a stops at the vertical position detection switch 55a.

On the other hand, the feed slider 33 of the tool transfer means 30, which received the tool, is the first tool magazine 10-1 by the reverse operation of the transfer cylinder 31 with the tool in the tool transfer port 34. Stop at the end of the range.

Subsequently, the side plate 12-1 is moved so that the empty tool port 13-1 in the first tool magazine 10-1 reaches a standby position for tool change.

At this time, the vertical cylinder 42 and the horizontal cylinder 46 of the first sub change means 40 drive the tool of the tool feed port 34 with the tool gripper 47 while driving by a constant control flow. It is attached / removed to the empty tool port 13-1 of 10-1).

More detailed operation control flow thereof causes the vertical cylinder 42 to stop when the sensing dog 44a at the end of the positioning bar 44 reaches the vertical position detecting switch 45c. (Gripping the tool of the tool feed port. One state)

Subsequently, the horizontal cylinder 46 is driven, and the gripper bracket 47a stops by reaching the horizontal position detecting switch 48b. (Grip picked up tool)

Subsequently, while the vertical cylinder 42 is driven downward again, the sensing dog 44a stops by reaching the position 45c to 45b of the vertical position detecting switch (state before the picked-up tool is inserted into the tool port).

Subsequently, the horizontal cylinder 46 is driven again, and the gripper bracket 47a reaches the horizontal position detecting switch 48a and stops. (The tool is inserted into the tool port.)

When the tool is transported by such an operation control flow, the vertical cylinder 42 is driven to finally reach the initial state where the detection dog 44a stops at the vertical position detection switch 45a.

On the other hand, when the desired tool feeding step is completed in the tool port 13-1 of the side plate 12-1, the side plate 12-1 is moved to between the tool pick-up means 14 and the tool boy 15a. The tool is moved to a position and stopped, and the tool pick-up means 14 of the same concept as the tool change means transfers the tool to the tool boy 15a and is finally transferred to the machine body side by the tool boy cylinder 15b. Will be done.

The above technique is a process of delivering one tool provided in the second tool magazine 10-2, which has been described in detail, but in fact, since it is composed of continuous organic relations with each other, it is very quick with little delay time. While the transfer process is provided, when the tool is to be inserted back into the second tool magazine 10-2, the detailed operation will be omitted since the operation is performed in the reverse order.

Applying the present invention as described above, it is possible to expect the speed of the work by greatly increasing the number of tools in response to the situation that the machining work is complicated and diversified, and also the installation form of the second tool magazine is not in the longitudinal direction It is configured in parallel to maximize space utilization.
