Here, if the width of the original panel 20 is 900 mm, the widths of the processed panels of the production orders 7 and 8 are 444 respectively.
Since it is mm, it can be seen that 444 × 2 <900 is satisfied and Condition 1 is satisfied.

Next, the work instruction data creating unit 13 searches the data of the laminated panel product number in the production plan data, and determines whether or not the processed panels of the production orders 7 and 8 that meet the condition 1 have the same product number. Is determined. Here, both EXLNXO
Therefore, since the product numbers are the same, it can be seen that Condition 2 is satisfied.

The work instruction data creation unit 13 instructs that, by processing these data, it is possible to take two processing panels having production orders 7 and 8 from one original plate panel.
The sheet picking work instruction data is sent to the drive control unit 12.

In the drive control unit 12, when the order of panel cutting processing performed according to the production plan data is the production order 7 based on the two-piece work instruction data, the processing panel 21 of the production order 7 is cut. Is performed in the vertical cutting machine 3, and then the belt conveyor 4 is rotated in the reverse direction while the end material panel 22 after the cutting is placed on the belt conveyor 4. Then, the scrap panel 22 is placed on the loading side 4 of the vertical cutting machine 3.
After returning to 1, the operator positions and cuts the processed panel 21 of the production rank 8 from this end material panel 22.

As a result, from one original plate panel 20,
Two processing panels 21 and 21 having the same product number are cut.

Cutting process procedure No. 2: When the condition for creating the two-sheet picking work instruction data in the work instruction data creating unit 13 is the above (2).

If the production planning data given from the data input section 14 to the work instruction data creating section 13 is the data shown in FIG. 3, the work instruction data creating section 13 is assumed.
Then, the width dimension data in the production plan data is searched, and first, two processing panels that meet the conditions 1 and 3 in (2) above are extracted. Here, the width of the original plate panel 20 is set to 90.
If the width is 0 mm, the widths of the processed panels in consecutive production orders 7 and 8 are 444 mm and 450 mm, respectively.
4 + 450 <900, which means that the conditions 1 and 3 are satisfied.

Next, the work instruction data creation unit 13 retrieves each data of the pattern and the height dimension in the production plan data, and the pattern and height of the machining panels having the production orders 7 and 8 which meet the condition 1 are the same. It is determined whether or not it is a dimension. Here, both are 30
2 and the height dimension is 1500, it can be seen that Condition 2 is satisfied.

The work instruction data creation unit 13 instructs that, by processing these data, it is possible to take two processed panels having production orders 7 and 8 from one original plate panel.
The sheet picking work instruction data is sent to the drive control unit 12.

In the drive control unit 12, when the order of panel cutting processing performed according to the production plan data is the production order 7 based on the two-piece work instruction data, the processing panel 21 of the production order 7 is cut. Is performed in the vertical cutting machine 3, and then the belt conveyor 4 is rotated in the reverse direction while the end material panel 22 after the cutting is placed on the belt conveyor 4. Then, the scrap panel 22 is placed on the loading side 4 of the vertical cutting machine 3.
After returning to 1, the operator positions and cuts the processed panel 21 of the production rank 8 from this end material panel 22.

Thus, from one original plate panel 20,
Two processing panels 21 and 21 having the same handle and size are cut.

Cutting process procedure 3: When the work instruction data creation condition in the work instruction data creation unit 13 is the above (3).

However, in order to execute the cutting process procedure in this case, it is necessary to configure the panel cutting process as shown in FIG. That is, in the configuration shown in FIG. 1, a belt conveyor 31 for transporting the end material panel 22 from the carry-out side 42 of the vertical cutting machine 3 to the carry-in side 41 of the vertical cutting machine 3 is arranged in parallel with the belt conveyor 4. Other configurations are similar to those shown in FIG.

Now, if the production planning data given from the data input unit 14 to the work instruction data creating unit 13 is the data shown in FIG. 5, the work instruction data creating unit 13 will be described.
Then, the width dimension data in the production plan data is searched, and first, two processed panels that meet the condition 1 of (2) above are extracted. Here, if the width of the original panel 20 is 900 mm, the widths of the processed panels of the production orders 2 and 13 are 42 respectively.
8mm and 437mm, so 428 + 437 <90
It can be seen that the condition becomes 0 and the condition 1 is satisfied. In addition, the width of the processed panels of production order 11 and 20 is 460 mm,
Since it is 400 mm, 460 + 400 <900, which means that the condition 1 is satisfied.

Next, the work instruction data creation unit 13 retrieves each data of the pattern and the height dimension in the production plan data, and the processing panels of the production orders 2 and 13 and the production order 11, which meet the condition 1. It is determined whether or not the 20 processed panels have the same pattern and height. Here, production order 2, 1
It can be seen that the condition 2 is satisfied because the processed panels of No. 3 each have the handle 302 and the height dimension of 1500. In addition, the processing panels with the highest ranks of 11 and 20 are both the handle 305 and the height dimension 15
Since it is 00, it can be seen that Condition 2 is satisfied.

Further, the work instruction data creating section 13 has a pair of processing panels of the above-mentioned two sets of processing panels (production order 2, 13 [corresponding to L, L + α]) satisfying these conditions 1 and 2,
In the processing panel of the production order 11, 20 [corresponding to M, M + β]), the production order of the upper processing panel and the production order of the lower processing panel of each group are compared, and whether the condition 3 is satisfied? Determine whether or not. Here, production order 2 <
Although the production rank is 11 (that is, L <M is satisfied), but the production rank is 20 <production rank 13 is not satisfied (that is, M + β <L + α is not satisfied), the condition 3 is satisfied.

In the work instruction data creating section 13, it is possible to obtain two processing panels having the production orders 3 and 13 and two processing panels having the production orders 11 and 20 from one original plate panel by the data processing. The two-sheet picking work instruction data for instructing is sent to the drive control unit 12.

In the drive control section 12, when the order of panel cutting processing performed according to the production plan data is the production order 3 based on the two-piece taking work instruction data, the processing panel 21 of the production order 3 is cut. Is performed in the vertical cutting machine 3, the cut end material panel 22 after the cutting is transferred onto the belt conveyor 31 provided adjacently, and the belt conveyor 31 is driven to return to the loading side 41 of the vertical cutting machine 3. After that, the standby state (the position of the end material panel 22 at this time is indicated by a broken line) is set at that position (the tip portion 311 of the belt conveyor 31).

After that, when the order of panel cutting processing becomes the production order 11, the processed panel 2 of the production order 11
After the cutting of No. 1 is performed by the vertical cutting machine 3, the cut end material panel 22 is transferred onto the belt conveyor 31. At this time, the end material panel 22 transferred before is placed on the front end portion 311 of the belt conveyor 31.

Then, when the order of the panel cutting process to be performed next becomes the production order 13, the drive control unit 12
The belt conveyor 31 is driven again, and the end material panel 22 waiting at the leading end 311 is transferred to the carry-in side conveyor 33 and conveyed to the carry-in side 41 of the vertical cutting machine 3. And later
The operator positions and cuts the processing panel 21 of the production order 13 from the end material panel 22.

At this time, the end material panel 22 transferred onto the belt conveyor 31 on the carry-out side 42 of the vertical cutting machine 3 is returned to the carry-in side 41 of the vertical cutting machine 3 which is the tip portion 311 of the belt conveyor 31. After that, it becomes a standby state at that position.

Then, when the order of the panel cutting process to be performed next is the production order 20, the drive control unit 12
The belt conveyor 31 is driven again, and the end material panel 22 waiting at the leading end 311 is transferred to the carry-in side conveyor 33 and conveyed to the carry-in side 41 of the vertical cutting machine 3. And later
