Abstract

PURPOSE: To make it possible to prepare efficiently and accurately various kinds of data in multiple appliques by preparing automatically the cutting data to cut a first applique piece from an original cloth based on contour data of the first applique piece stored by one input. CONSTITUTION: Contour data D1 for the first applique piece is inputted and stored in RAM in a control unit by affixing an L-shaped paper pattern 8 with the same size and shape as the first applique piece onto a board of a digitizer 2, and by picking up corner points C1 through C6 forming the contour and arc points R1 through R3 by using a pointing device 41. Cutting data D2a is prepared automatically that is used to cut, for example, the first applique piece from the original cloth based on the contour data D1. Then, the first applique is cut off from the original cloth, and tacking stitches are formed on the cloth by inserting floppy disks that have recorded the cutting data into a cutting machine and an embroidering machine, respectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data creating apparatus for concentrically arranging a plurality of appliqué pieces which are substantially similar to each other and embroidering them on a cloth to form multiple appliqués. In addition, concentric placement means that
It means that the appliqué pieces are arranged so that the central portions of the shapes such as characters, figures, symbols, etc., are made to coincide with each other.

[0002]

2. Description of the Related Art In order to enhance a color or a three-dimensional appearance, for example, an L-shaped light blue applique piece is sewn on a cloth by embroidery, and then a substantially similar shape L which is slightly smaller than the appliqué piece is formed. Sometimes blue applique pieces forming a letter are concentrically arranged so as to overlap in the thickness direction and sewn on by embroidery to form a multiple applique.

Conventionally, various data necessary for creating such a multiple appliqué using a cutting machine and an embroidery sewing machine have been created separately for each appliqué piece. That is, for the L-shaped appliqué piece, first, the pattern is attached to the digitizer of the cutting data creating device, and a large number of points on the contour of the same pattern are picked up by a pointing device such as a button cursor or the like and the contour is extracted. Data is input and cutting data is created from this contour data. next,
The same pattern is reattached to the digitizer of the embroidery data creating device, the contour data is input, and the temporary sewing data necessary for positioning and arranging the appliqué piece on the fabric is created from the contour data. Similarly, the contour data is input again, and the tack sewing data necessary for tack-stitching the appliqué piece to the fabric are created from this contour data. The inner circumference data and the outer circumference data are input by alternately picking up a large number of points on the inner circumference line along the inside of the contour of the pattern and a large number of points on the outer circumference line along the outside, and from this inner circumference data and outer circumference data. Create satin stitch data required for embroidering appliqué pieces on fabric. For the L-shaped appliqué piece, which is one size smaller, the pattern data is used to repeat the input of contour data as many times as the L-shaped appliqué piece.

[0004]

As described above, it is troublesome to repeatedly pick up the pattern paper and input the contour data every time the cutting data, the temporary sewing data, the tack sewing data and the satin stitch data of the appliqué piece are created. In addition, in the case of multiple appliqués, it was necessary to input the contour data separately for each appliqué piece, which took a lot of labor and time. Further, if there is a deviation in the contour data that has been input many times, there is a risk that the created data will be deviated from each other and appear as a defect in the multiple appliqué.

An object of the present invention is to solve the above problems and efficiently create cutting data, temporary stitch data, tack stitch data, and satin stitch data of a plurality of appliqué pieces constituting a multiple appliqué with minimum effort. Along with
The purpose is to make them correspond exactly to each other so that no defects occur in the multiple appliqués.

[0006]

In order to achieve the above-mentioned object, a data applicator for multiple appliques according to the present invention, based on the contour data of the first applique piece stored by one input, (a) Cutting data for cutting the first applique piece from the base cloth, (b) Temporary stitching data for positioning the first applique piece on the cloth, and (c) Stop for sewing the first applique piece on the cloth. Sewing data,
(D) Satin stitch data for embroidering the first appliqué piece on the fabric, and (e) a second appliqué piece that is substantially similar to the first appliqué piece and is arranged concentrically from the original fabric. Cutting data for cutting, (f) temporary sewing data for positioning the second appliqué piece on the fabric, (g) tacking data for tacking the second appliqué piece on the fabric, (h) fabric Further, it is provided with a data creating means for automatically creating all satin stitch data for embroidering the second applique piece.

Here, the second applique piece is arranged so as to overlap with the first applique piece in the thickness direction, and the second applique piece is arranged so as not to overlap with the first applique piece in the thickness direction. There is. Also, the first appliqué piece,
The word of the second appliqué piece is merely an expression for distinguishing the two, which may be arranged below, and is not limited to two appliqué pieces, and three or more appliqué pieces are not limited thereto. Including the case of placing pieces.

Further, the data creating means also creates the trimming data necessary for the trimming along the edge of the satin stitch of the first appliqué piece or the second appliqué piece, based on the contour data of the first appliqué piece. You can The trimming stitch is not limited to a particular motif, and specific examples thereof include triple stitch, circular stitch, triangular stitch, square stitch, hexagonal stitch, star stitch, satin stitch and the like.

The contour data of the first appliqué piece is 1
The data is stored by inputting once, but the time of inputting / storing is not limited to the time of data creation of the present invention, and may be before that. As a means for inputting contour data, a digitizer (including a tablet, which is the name of a small digitizer),
An image scanner, a touch panel, a light pen, a mouse, a track ball, a CCD camera, etc. can be exemplified. A microcomputer can be exemplified as the data creating means.

[0010]

According to the multiple appliqué production apparatus of the present invention,
Based on the contour data of the first appliqué piece stored by one input, the cutting data, the temporary stitching data, the tie stitching data, the satin stitch data of the first appliqué piece, and the substantially similar shape to the first appliqué piece are obtained. All the cutting data, temporary stitching data, tacking data, and satin stitch data of the second appliqué pieces that are arranged concentrically with each other are automatically created, so the work of inputting contour data can be done with a minimum amount of work. Can be created efficiently. Further, since the created data correspond accurately and do not shift from each other, no defect occurs in the multiple appliqué.

These steps will be described in detail by taking as an example the data creation in the case where the embroidery sewing is performed by concentrically arranging so as to overlap.

(1) Input of Contour Data of First Applique Piece As shown in FIG. 3 (a), an L-shaped paper pattern 8 having the same size and shape as the first applique piece is attached to the board surface of the digitizer 2, Each corner point C1, which constitutes the L-shaped contour
, C6 and arc constituent points R1, ..., R3 are picked up by a pointing device 41 such as a button cursor, a stylus pen, etc. to input the contour data D1 of the first applique piece, and to the RAM of the control device 1. Remember. As shown in FIG. 3B, the display 4 has
The points that have been picked up are displayed with a line connecting them.

At this input, the first corner point C1
Is picked up as a start point S, and a point slightly beyond the last corner point C6 (the same point as C1) is picked up as an end point E. This is preferable because it always intersects with the part and there is no uncut portion.

The contour data D1 can be input more easily and quickly by using the image scanner 17. Also, the contour data D1 already stored in the floppy disk or magnetic tape with one input.
May be read from the data reading device 18.

(2) Automatic Creation of Cutting Data for First Applique Piece and Second Applique Piece The control device 1 controls the contour data D as shown in FIG. 4 (a).
The cutting data D2a for cutting the first appliqué piece from the original cloth is automatically created from 1, and as shown in FIG.
As shown in (b), by offsetting the contour data D1 inward by a certain amount, the cutting data D2b is a smaller size L for cutting the second applique piece from the base cloth.
Automatically created. This offset amount can be arbitrarily set by inputting it to the control device 1 from the keyboard 3 or the mouse 19 in advance. These cutting data D2a,
D2b is recorded on the floppy disk FD1 by the floppy disk device 6.

(3) Automatic Creation of Embroidery Data for First Applique Piece and Second Applique Piece Next, as shown in FIG. 5A, the control device 1 uses the contour data D1 to apply the first applique to the cloth. Temporary stitching data D3a for positioning the piece is automatically created, and as shown in FIG. 5B, from the contour data D1,
The temporary sewing data D3b for positioning the second appliqué piece on the fabric is automatically created. Each of the temporary stitching data D3a and D3b of this embodiment is the data of walking stitch,
The dimensions and shapes are the cutting data D2a and D2, respectively.
same as b. These temporary sewing data D3a and D3b
Is recorded on the floppy disk FD2 by the floppy disk device 6.

Next, as shown in FIG. 6A, the control device 1 automatically creates the tie stitch data D4a for tie stitching the first appliqué piece to the fabric based on the contour data D1. At the same time, as shown in FIG.
Based on the contour data D1, the tack sewing data D4b for fastening the second appliqué piece to the fabric is automatically created. In this embodiment, the E-stitch data was created based on the stitching direction of the E-stitch and the number of stitches from the stitching to the stitching which were input from the keyboard 3 to the control device 1 in advance. However, it is possible to use the different types of stitches as the stop stitch data. These tacking data D4a and D4b are recorded on the floppy disk FD2.

As shown in FIG. 7A, the control device 1 uses the contour data D1 to satin stitch data D5 for embroidering the first appliqué piece on the fabric.
a is automatically created, and as shown in FIG. 7B, satin stitch data D5 for embroidering the second applique piece on the fabric based on the contour data D1.
automatically create b. Specifically, inner circumference data along the inner side of the contour data D1 and outer circumference data along the outer side are automatically created, and satin stitch data D5a and D5b are automatically created from the inner circumference data and the outer circumference data. The outer edge dimensions of the satin stitch data D5a and D5b are set to be substantially the same as or slightly larger than the outer edge dimension of each applique piece. These satin stitch data D5a and D5b are recorded on the floppy disk FD2.

The embroidery code of the satin stitch data D5a and D5b output in this embodiment has 2 stitches per stitch.
Byte XY data (7 bits in binary, therefore 12
7)) and 1-byte function data in total, and in particular, the function data includes a 1-bit start code, a 2-bit polarity code, and 5 other bits. Since various functions can be specified up to 31 types by 5 bits,
It can be said that the embroidery code has excellent expandability and applicability (it is called the U code in the embroidery sewing machine product by the applicant of the present application). Of these 31 types, for example, 18 types can be used for designating the needle number of the multi-needle embroidery head 21, that is, for designating the color of the embroidery thread.
It is possible to sew multicolored embroidery while automatically changing the needle number, that is, automatically changing the color.

Besides, several kinds of embroidery codes are known, and of course, satin stitch data D5a, D5b.
Can be output with these embroidery codes, but for example, in the case of an embroidery code in which the function data is composed only of jumps and stops, a stop signal is output every time the color of the embroidery thread is changed, This is inconvenient because the embroidery sewing machine must specify stop, thread trimming, color change, etc.

Finally, as shown in FIG. 8A, the control device 1 creates, based on the contour data D1, the trimming data D6a necessary for the trimming along the edges of the satin stitch data D5a. At the same time, as shown in FIG. 8B, based on the contour data D1, edge trimming data D6b necessary for trimming along the edge of the satin stitch data D5b is created. Therefore, a floppy disk or magnetic tape storing a plurality of kinds of motif data is placed on the data reading device 18, and desired motif data can be selected and read by operating the control device 1 and the keyboard 3. . Further, these motif data can be stored in the ROM in the control device 1, the external storage device, or the like.

Then, the control device 1 sets the size and the amount of progress of one unit of the selected motif data, and further determines whether the edge decoration sewing data should be along the outer edge or the inner edge of the satin stitch data. Is set or whether it is set apart from the edge or set apart from the edge (in the latter case, the separation distance is also set). Further, the control device 1 arranges the set motif data so as to proceed along the edges of the satin stitch data D5a and D5b,
Margin sewing data D6a and D6b are created. In this embodiment, the trimming stitching data D6a is arranged slightly apart from the outer edge of the satin stitch data D5a, and the trimming stitching data D6b is matched and arranged along the outer edge of the satin stitch data D5b.
