Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention sets a work offset value and writes a work offset value when a large number of pallets carrying work are sequentially carried into a machine side and a predetermined machining is performed. The present invention relates to a work offset value setting device suitable for preventing correction errors.

[0002]

2. Description of the Related Art A control unit has a storage section for storing a program for setting a work offset value, and a program for an offset value corresponding to each work is stored and stored in advance. However, when many kinds of works are mounted on a pallet and a predetermined process is carried out, there are many cases in which the work cannot be processed as it is because of the positional deviation between the pallet and the work. Therefore, it is necessary to correct the offset value. FIG. 3 shows a schematic configuration of a conventional work offset value setting device. A predetermined pallet 5 is delivered from the multi-pallet changer 10 via the pallet delivery unit 9 and mounted on the setup station 4. A work (not shown) is attached to a predetermined position on the pallet 5 on the setup station 4. In that state, the measuring means 8 measures the offset value and the like. On the other hand, the work offset value set value storage unit 3a in the control device 2a stores in advance a work offset value set value with an offset number corresponding to the pallet number. When the offset value of a predetermined pallet 5 is measured on the setup station 4, the pallet number / offset number correspondence table 11 created in advance
Then, the offset number corresponding to the pallet number of the predetermined pallet 5 is called, and the offset value is written by the manual operation. On the other hand, when the predetermined pallet 5 is returned from the setup station 4 to the multi-pallet changer 10 and carried into the machine 6 (hereinafter referred to as M / C6), the control device 2a sets the work offset value corresponding to the pallet number. The machine control unit 7a of the control device 2a
Offset control of M / C6 is performed via.

[0003]

In the case of the conventional work offset setting device shown in FIG. 3, the offset value is manually written as described above. Therefore, there is a problem that the offset value is erroneously written in an offset number different from the pallet number of the predetermined pallet 5. Further, the manual writing work requires a lot of work time. Further, it is necessary to create in advance the pallet number / offset number correspondence table 11 that associates the pallet number with the offset number, which is extremely complicated.

The present invention solves the above problems by writing the offset value of a predetermined pallet into a predetermined work offset value setting program and recalling the offset value stored at the time of loading the pallet. An object of the present invention is to provide a work offset value setting device in which predetermined offset control is performed.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a multi-pallet changer and a predetermined pallet on the multi-pallet changer,
A setup station for mounting a work on the pallet and obtaining a work offset value of the work;
In a work offset value setting device provided with a control device including a work offset value setting program storage part, a machine control part, etc., a back editing part is provided in the control device, and a predetermined pallet is mounted on the setup station. At this point, the work offset value setting program is searched for in the back editing unit, the work offset value on a predetermined pallet is written and stored in the back editing unit, and the predetermined pallet is carried into the machine (M / C) side. In this case, the work offset value corresponding to the pallet is automatically called from the back editing unit to control the work offset based on the work offset value.

[0006]

The work offset value of the predetermined pallet at the setup station is automatically written and stored in the back editing section in the control device. The back editing section is searched by the work offset value setting program, and the one corresponding to the pallet number of a predetermined pallet is automatically searched. Therefore, the work offset value of the predetermined pallet is not written in the work offset value setting program having the different number. On the other hand, when a predetermined pallet is carried into the M / C side, the work offset value stored in the back editing unit is called, and offset control is performed based on the work offset value.
