Condition 3: The processing panel with the same product number that satisfies the condition 1 is continuously produced. (3) Based on the given production plan data, two processing panels satisfying the following three conditions are extracted, and the two-panel work instruction data of the extracted processing panel is created.

Condition 1: Sum of cut dimensions of certain two processed panels ≦ width of original plate panel Condition 2: Same pattern and size of two processed panels satisfying Condition 1 Condition 3: Satisfy conditions 1 and 2 In a set of processing panels (production order L, L + α and production order M, M + β), L <
M, and M + β <L + α Two Panels Not Satisfied Cutting Procedure Procedure 1: 1 in Work Instruction Data Creation Unit 13
The case where the preparation condition of the sheet taking work instruction data is the above (1).

Assuming that the production plan data given from the data input unit 14 to the work instruction data creating unit 13 is the data shown in FIG.
Then, the width dimension data in the production plan data is searched, and first, two processing panels meeting condition 1 of the above (1) are extracted. Here, assuming that the width of the original plate panel 20 is 900 mm, the widths of the processed panels in the production orders 7 and 8 are 444, respectively.
mm, 444 × 2 <900, which satisfies the condition 1.

Next, the work instruction data creating unit 13 searches the data of the bonded panel part number in the production plan data, and determines whether or not the processed panels of the production ranks 7 and 8 that meet the condition 1 have the same part number. Is determined. Here, both are EXLNXO
And the same part number, it is understood that the condition 2 is satisfied.

The work instruction data creating unit 13 instructs that two processing panels of production orders 7 and 8 can be taken from one original plate panel by these data processing.
The sheet taking work instruction data is sent to the drive control unit 12.

The drive control unit 12 cuts the processing panel 21 in the production order 7 when the order of panel cutting performed in accordance with the production plan data becomes the production order 7 based on the two-sheet taking operation instruction data. Is performed in the vertical cutting machine 3, and the belt conveyor 4 is rotated in the reverse direction while the cut end material panel 22 is placed on the belt conveyor 4. Then, the offcut panel 22 is moved to the loading side 4 of the vertical cutting machine 3.
After returning to 1, the operator performs positioning, and cuts the processing panel 21 of the production order 8 from the end material panel 22.

Thus, from one original plate panel 20,
Two processing panels 21 and 21 of the same product number are cut.

Cutting processing procedure # 2: The case where the condition for creating the two-sheet taking work instruction data in the work instruction data creation unit 13 is the above (2).

Assuming that the production plan data given from the data input unit 14 to the work instruction data creating unit 13 is the data shown in FIG.
Then, the width dimension data in the production plan data is searched, and first, two processing panels meeting the conditions 1 and 3 of the above (2) 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 satisfies the conditions 1 and 3.

Next, the work instruction data creating section 13 searches each data of the pattern and the height dimension in the production plan data, and the processing panels of the production ranks 7 and 8 which match the condition 1 have the same pattern and height. It is determined whether or not it is a dimension. Here, both patterns are 30
2. Since the height dimension is 1500, it is understood that the condition 2 is satisfied.

The work instruction data creating unit 13 instructs that two processing panels of production orders 7 and 8 can be taken from one original plate panel by these data processing.
The sheet taking work instruction data is sent to the drive control unit 12.

When the order of panel cutting performed in accordance with the production plan data becomes the production order 7 based on the two-sheet taking operation instruction data, the drive control unit 12 cuts the processing panel 21 of the production order 7. Is performed in the vertical cutting machine 3, and the belt conveyor 4 is rotated in the reverse direction while the cut end material panel 22 is placed on the belt conveyor 4. Then, the offcut panel 22 is moved to the loading side 4 of the vertical cutting machine 3.
After returning to 1, the operator performs positioning, and cuts the processing panel 21 of the production order 8 from the end material panel 22.

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

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

However, in order to execute the cutting procedure in this case, the panel cutting step needs to be configured as shown in FIG. That is, in the configuration shown in FIG. 1, the belt conveyor 31 for transporting the scrap panel 22 from the discharge side 42 of the vertical cutting machine 3 to the carry-in side 41 of the vertical cutting machine 3 is provided in parallel with the belt conveyor 4. Other configurations are the same as those shown in FIG.

Assume that the production plan data provided from the data input unit 14 to the work instruction data creating unit 13 is the data shown in FIG.
Then, the data of the width dimension in the production plan data is searched, and first, two processing panels meeting condition 1 of the above (2) are extracted. Here, assuming that the width of the original plate panel 20 is 900 mm, the width of the processed panels of the production orders 3 and 13 is 42 mm, respectively.
8 mm, 437 mm, 428 + 437 <90
0, which satisfies the condition 1. In addition, the width of the processing panels of production orders 11 and 20 is 460 mm, respectively.
Since it is 400 mm, it can be seen that 460 + 400 <900, which satisfies the condition 1.

Next, the work instruction data creating section 13 searches for data of patterns and height dimensions in the production plan data, and processes the production panels of the production orders 3 and 13 which meet the condition 1 and the production orders 11 and 13. It is determined whether or not the 20 processing panels have the same pattern and height. Here, production rank 3 , 1
Since all of the processed panels No. 3 have the pattern 302 and the height dimension 1500, it is understood that the condition 2 is satisfied. In addition, the processing panels of the first and second highest ranks 11 and 20 both have the pattern 305 and the height dimension 15
Since it is 00, it is understood that the condition 2 is satisfied.

Further, the work instruction data creating unit 13 includes two sets of processing panels (production ranks 3 , 13 (corresponding to L, L + α)) satisfying these conditions 1 and 2.
In the processing order of the set of production ranks 11 and 20 (corresponding to M, M + β), the production rank of the upper processing panel and the production rank of the lower processing panel of each set are compared, and whether condition 3 is satisfied or not. It determines whether or not. Here, production order 3 <
Although the production order is 11 (that is, L <M holds), the production order 20 <the production order 13 does not hold (that is, M + β <L + α does not hold), so that the condition 3 is satisfied.

In the work instruction data creating section 13, the processing panels of the production orders 3 and 13 and the processing panels of the production orders 11 and 20 can each take two sheets from one original plate panel by these data processing. Is transmitted to the drive control unit 12.

The drive control unit 12 cuts the processing panel 21 of the production order 3 when the order of panel cutting performed in accordance with the production plan data becomes the production order 3 based on the two-sheet taking operation instruction data. Is carried out in the vertical cutting machine 3, and the cut off end material panel 22 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, at that position (the leading end 311 of the belt conveyor 31), a standby state is established (the position of the end material panel 22 at this time is indicated by a broken line).

Thereafter, when the order of the panel cutting process becomes the production order 11, the processing panel 2 in the production order 11
After the first cutting is performed in the vertical cutting machine 3, the cut end panel 22 is transferred onto the belt conveyor 31. At this time, the end material panel 22 that has been transferred to the front end portion 311 of the belt conveyor 31 has been placed.

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

At this time, the scrap panel 22 transferred onto the belt conveyor 31 on the discharge side 42 of the vertical cutting machine 3 is returned to the loading side 41 of the vertical cutting machine 3 which is the tip 311 of the belt conveyor 31. After that, a standby state is established at that position.

Then, when the order of the panel cutting to be performed next becomes the production order 20, the drive control unit 12
The belt conveyor 31 is driven again, and the scrap panel 22 waiting at the leading end 311 is transferred to the carry-in side conveyor 33 and is conveyed to the carry-in side 41 of the vertical cutting machine 3. And later
The operator performs positioning and cuts the processing panel 21 of the production order 20 from the end material panel 22.

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

In each of the above cutting procedures, the movement of the processing panel 21 and the end material panel 22 from conveyor to conveyor is not shown, but is performed by a vacuum lift or the like or by a slide method. It is possible.

[0046]

According to the panel cutting apparatus of the present invention, the production order of two processing panels that can be cut out from the same original panel is extracted from the production plan data, and two-sheet work instruction data is created in accordance with the extracted data. Then, based on the two-sheet work instruction data, the first processing panel of the two extracted processing panels is cut by a cutting machine, and then the next processing panel is cut from the scrap material panel. As a result, it is possible to process two sheets from one original sheet panel without letting the site worker judge and process the types of processing panels that can be taken two sheets, the production order of the processing panels, the timing of input to the cutting machine, etc. Since the panel can be cut, there is an effect that the scrap panel can be efficiently reused.
