4 is displayed as created by a certain operation on the CAD. The marker has an area of a certain area, which area corresponds to the area of the sheet-like member 2 such as a pattern-matching cloth currently disposed on the cutting bed 1 of the automatic cutting apparatus or in the effective area of the bed. . This marker 4
No. 4 efficiently arranges various necessary pattern diagrams 44P in the area.

Reference numeral 44S denotes a vertical or horizontal pattern line, and these pattern lines are merely CAD patterns as described above.
It is displayed by calculation of the technique, and there is no guarantee that it matches the pattern line of the sheet-like member such as the pattern-matching cloth currently arranged on the cutting bed 1.

According to the present invention, a plurality of zones are set for such a marker in the vertical direction, in the horizontal direction, or both in the vertical direction via virtual dividing lines. One or two points in the zone are set as reference points. The setting may be automatically given in advance by processing on a program, or may be given using input means such as a cursor. In the latter case, the coordinate position is read by the VRAM, but in any case, the coordinate position of the reference point is easily read and stored. In the present embodiment, the marker 44 is divided into two zones by a one-dot chain line 44Z, and each reference point is displayed as x.

According to the illustrated embodiment, one point of a sheet-like member 2 such as a pattern-matching cloth currently stacked on the cutting bed 1 corresponding to the coordinate position stored for each zone is indicated by:
The image sensor of the cutting head is moved to display the vicinity of the point. In this embodiment, the display section 42 is provided on the upper left side of the screen 40. Further, an enlarged portion of the surrounding line 44L in the marker 44 is shown on the display unit 42 as an example.

In the enlarged display section 42, a part of the marker corresponding to the reference point x and a part of the sheet-like member corresponding to the reference point x are displayed instead of the entire area of the marker zone. However, the entire zone may be displayed. However, if the scan range of the image sensor is widened, it is natural that the display takes time.

In the illustrated embodiment, the thin lines in the enlarged display section 42 indicate the pattern lines of the marker, and the dotted lines indicate the pattern lines of the sheet-like member. 42L indicates a portion surrounded by an ellipse, and its enlarged portion is shown in FIG. 2, and the description is as follows.

The vicinity of the reference point of the sheet-like member is displayed on a screen, one pattern line is selected from the displayed pattern lines, and input means such as a stylus pen 106 is used to move the image sensor to the one point. And the key switch is used to display the point a and read its position, and to move the image sensor by the same means to match the pattern line in the same zone of the marker. Point b is displayed by the key switch, and the moving position is read.

As described above, it is possible to correct the arrangement position of the pattern diagram in each zone based on the position data read for each zone and to correct the marker data for all the zones by the CAD technique. It is not necessary to specify it because it is known.

In some cases, the pattern line of the pattern matching fabric 2 actually stacked on the cutting bed 1 may be formed not as a vertical line or a horizontal line but as an obliquely bent line in one part.
In this case, two reference points need to be set for the corresponding marker zone.

According to the present invention, a pattern mold piece in consideration of a pattern is obtained by an automatic cutting device as intended.
The pattern line is almost coincident with the sheet-like member such as the material to be cut, and the layout position of each pattern diagram is corrected.The correction accuracy can be selected according to the application, and the correction work is more efficient.
An easy-to-use marker correction system and method for a sheet-like member such as a pattern matching cloth can be obtained.
