[0001]
[Industrial application fields]
The present invention relates to a method for creating applique cutting data and embroidery data.
[0002]
[Prior art and problems to be solved by the invention]
As shown in FIG. 15, in the front type uniform outerwear 50, the lower front body 51 and the upper front body 52 are superposed and separated at a certain overlap. When an applique representing the team name is embroidery stitched to these front bodies 51, 52, the middle of the applique may be divided at the overlapping portion of the lower front body 51 and the upper front body 52. In such a case, when the lower front body 51 and the upper front body 52 are superposed, the lower and upper parts are formed so as to form a continuous general outline by superposing them at a certain overlap. Applique cloth pieces 53 and 54 are used.
[0003]
The applique fabric pieces 53 and 54 shown in FIGS. 15 and 16 constitute a continuous character (an overall outline) of “Angels” when they are superposed. The lower applique fabric piece 53 ends at the right position in the “g” shape, and its end edge is a superposed edge 55, and the upper applique fabric piece 54 ends at the left position in the “g” shape. Thus, the end edge is a polymerization edge 56. The lower applique fabric piece 53 is arranged on the lower front body 51 and the upper applique fabric piece 54 is arranged on the upper front body 52, and embroidery is sewn with a satin stitch 57 by an automatically controlled embroidery sewing machine.
[0004]
Conventionally, the cutting data and embroidery data for the lower and upper applique fabric pieces 53 and 54 as described above have been created separately as follows, and it has been necessary to input each contour data many times. It was very time consuming.
[0005]
(1) Creation of cutting data and embroidery data for the lower appliqué piece 53 (1) Paste a pattern with the outline of the upper applique piece on the digitizer and pick up the outline of the outline with a pointing device. Thus, the contour data is input. From this contour data, cutting data for causing the cutting machine to cut the applique fabric piece is generated by the cutting data generating device.
[0006]
(2) The contour data of the lower applique cloth is input again. From this contour data, positioning embroidery data for causing the embroidery sewing machine to perform temporary sewing (walking sewing) of the fabric is generated from the contour data.
[0007]
(3) Three times, the contour data of the lower applique cloth is inputted, and the inner circumference data and the outer circumference data along the contour data are inputted and created. Based on the contour data and the inner circumference data, the embroidery data creation device creates backtack data for causing the embroidery sewing machine to backt the applique fabric piece.
[0008]
(4) Satin stitch data for forming the satin stitch 57 on the embroidery sewing machine is created from the inner circumference data and the outer circumference data by the embroidery data creation device.
[0009]
(2) Creation of cutting data and embroidery data for the upper applique cloth piece 54 The upper applique cloth piece 54 is also the same as the lower applique cloth piece 53 as in the above (1), (2), and (3) ▲. Cut data and embroidery data (positioning temporary stitching data, backtack data, and satin stitch data) are created by the procedure of 4 ▼.
[0010]
In order to clarify or emphasize the border of the applique, it may be desired to change the color of the applique fabric pieces 53 and 54 and the color of the satin stitch 57. For example, when the appliqué cloth pieces 53 and 54 are blue, the satin stitch 57 is made red. However, in this example, if the overlapping edge 56 of the upper applique fabric piece 54 is sewn with a red satin stitch, when the applique fabric pieces 53 and 54 are superposed, the red satin stitch becomes blue. Since the applicator cloth pieces 53 and 54 cross the “g” shape, the appearance looks worse.
[0011]
Therefore, conventionally, as shown in FIG. 16, the overlapping edge 56 of the upper applique cloth 54 is not sewn with a red satin stitch, and the upper front body 52 is removed from the automatically controlled embroidery sewing machine. After that, it was set again on another small embroidery sewing machine, and only the overlapping edge 56 was sewn with the blue satin stitch 58. For this reason, processing efficiency was low.
[0012]
The object of the present invention is to solve the above-mentioned problems and to input the total contour data and the overlapping edge data once in the applique where the upper and lower applique fabric pieces are overlapped at a certain overlap to form a continuous total contour. To make it possible to efficiently create cutting data or embroidery data for both applique fabrics depending on the work, and to improve the processing efficiency when the color of the applique fabric and the color of the satin stitch are different. It is in.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, according to the method of creating applique cutting data and embroidery data of the present invention, the overall contour data of both applique fabric pieces when the upper and lower applique fabric pieces are superposed at a certain overlap allowance. , A step of inputting each overlapping edge data of the lower and upper applique fabric pieces, and a step of creating each contour data of the lower and upper applique cloth pieces from the overall contour data and each overlapping edge data. And a step of creating cutting data for the lower and upper applique fabric pieces based on the contour data, and a step of creating each embroidery data for the lower and upper applique fabric pieces based on the contour data. Configured.
[0015]
In the step of creating the embroidery data, from each contour data, each positioning temporary stitching data for forming temporary stitching is formed on the lower and upper fabrics, and the starting point of the positioning temporary stitching data is set as each overlapping edge data. It is preferable to set the crossing point.
[0016]
Also, in the step of creating the embroidery data, inner circumference data and outer circumference data along each contour data are created, and the lower and upper applique fabric pieces are respectively taken from the inner circumference data and the outer circumference data. Creates satin stitch data to sew on the fabric and switches between the satin stitch thread that sews the overlapping edge of the upper applique cloth piece and the satin stitch thread that sews the other edge of the applique cloth piece. It is preferable to create thread change data for this purpose.
[0017]
In addition, the cloth or cloth piece referred to in the present invention has a broad meaning including equivalents such as leather, resin sheets, and composite sheets. In the above method, examples of means for inputting contour data include a digitizer (including a tablet which is a designation of a small digitizer), an image scanner, a touch panel, a light pen, a mouse, a track ball, and the like. Moreover, a microcomputer can be illustrated as a means for creating inner circumference data, outer circumference data, and satin stitch data.
[0018]
[Action]
According to the applique cutting data creation method or the embroidery data creation method of the present invention, in the applique where the upper and lower applique fabric pieces overlap each other at a certain overlap, a continuous overall contour is obtained. Further, the cutting data or the embroidery data of both applique cloth pieces can be efficiently created by the overlapping edge data input operation.
[0019]
Further, in the step of creating the embroidery data, each positioning temporary stitching data for forming temporary stitches on the lower and upper fabrics is created from each contour data, and the starting point of the positioning temporary stitching data is set to each overlapping edge data. Since the start point of temporary sewing comes to the overlapping edge of each fabric, it is easy to match this start point to the needle position of the embroidery sewing machine.
[0020]
Further, in the step of creating the embroidery data, inner circumference data and outer circumference data along each contour data are created, and the lower and upper applique fabric pieces are respectively placed on the lower and upper fabrics from the inner circumference data and the outer circumference data. To create satin stitch data for sewing, and to switch between the satin stitch thread that sews the overlapping edge of the upper applique cloth piece and the satin stitch thread that stitches the other edge of the applique cloth piece If this thread change data is created, this thread change data can be input to an automatically controlled embroidery machine. For this reason, even for the applique where the color of the applique cloth and the color of the satin stitch are different, about the overlapping edge of the upper applique cloth piece that will cross the middle of the general outline of the applique, The color of the satin stitch can be switched to approximately the same as the color of the appliqué cloth piece, and the overlapping edge and other parts can be sewn with the same embroidery sewing machine, so that the processing efficiency can be improved.
