Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an embroidery machine capable of forming decorative patterns with practical functions.

[Prior art and its problems]

Sewing patterns produced by conventional sewing machines are divided into decorative sewing patterns and sewing patterns with practical functions.There are many sewing patterns with practical functions, examples of which are shown in Figs. 8 and 9. As shown in the figure, there are zigzag stitches A, three-point zigzag B, etc., which are used as darning stitches to create a "serrated part" of the fabric.
The darning stitches shown in Figures 8 and 9 have a very sloppy finish.
No matter how much I tried to make it less noticeable, such as by using threads of the same color as the fabric, I could not get rid of its unnaturalness. On the other hand, the sewing patterns produced by the embroidery machine have a problem in that, except for those that have a display function, such as character embroidery, they do not have any practical function due to their nature, and are limited to decorative patterns.

[Effects of means and ideas for solving problems]

The present invention provides an embroidery machine that can form decorative patterns with practical functions (hereinafter referred to as practical decorative sewing patterns) in addition to ordinary decorative sewing patterns. That is, the present invention provides an embroidery machine with a first storage means in which decorative sewing pattern data for ordinary decorative sewing patterns such as ordinary characters and patterns are stored, and a plurality of sewing patterns having different practical functions. a plurality of practical decorative sewing patterns having stitch types suitable for practical functions are determined in advance for each of the groups, and a second storage means storing practical decorative sewing pattern data for these practical decorative sewing patterns; and a keyboard for selecting ordinary decorative sewing pattern data or practical decorative sewing pattern data from the first storage means and the second storage means, so that practical decorative sewing patterns can be formed in addition to ordinary decorative sewing patterns. When forming practical decorative stitch patterns, the user must
Select the desired standard pattern data for multiple standard practical decorative sewing pattern data, load it into the embroidery machine, and embroider the pattern data in the perpendicular X direction and on the cloth surface based on the standard pattern data selected by keyboard operation. It can be expanded or contracted equally in the Y direction, expanded or contracted independently in the X and Y directions to form a practical decorative sewing pattern, or the required outer diameter dimensions in the X and Y directions on the fabric surface. By inputting It has the remarkable effect of greatly expanding the range of applications for sewing with an embroidery machine, such as being easily formed in different shapes and sizes.

【Example】

The general structure of a embroidery machine according to an embodiment of the present invention will be described below with reference to FIG. In the figure, the stitching machine 1 includes a sewing machine 2 that forms lockstitch stitches, an XY motor 4 that is XY-controlled in synchronization with a signal from an upper shaft sensor 3 of the sewing machine 2, and a sewing machine 2 that forms lockstitch stitches.
Driven by the XY motor 4, the cloth frame 5 is
It is equipped with an XY mechanism 6 for control. Further, decorative sewing pattern data for ordinary stitching of letters, patterns, etc. and practical decorative sewing pattern data to be described later are stored in a plurality of floppy disks (FD1, FD2, . . . ) as external storage media. Hereinafter, the floppy disk (one or more disks) storing decorative sewing pattern data for ordinary embroidery will be referred to as the first storage means, and the floppy disk (one disk) storing practical decorative sewing pattern data will be referred to as the first storage means. or a plurality of sheets) is called a second storage means. The user inserts the required floppy disk into the floppy disk drive (FDD) and selects the sewing pattern using the keyboard (KEY).
The corresponding pattern data on the floppy disk is read into a temporary storage device (RAM). In this embodiment, these two types of decorative sewing pattern data and practical decorative sewing pattern data are stored on a floppy disk as an external storage medium, except for the program storage area of the read-only memory ROM shown in FIG. It is also possible to store them in advance in separate storage areas. Set the size of the sewing pattern using the keyboard (KEY), align the sewing position on the base fabric using the movement keys (not shown), and press the start button (not shown) for the first time. The XY motor 4 is controlled in synchronization with the signal from the upper shaft sensor 3 that is generated every rotation of the sewing machine, and with the needle bar of the sewing machine stopped near the top dead center, the The set cloth is relatively moved along the outline of the sewing pattern. Then, when you press the start button for the second time,
A sewing pattern is formed on the cloth based on the pattern data.
Multiple floppy disks (FD1, FD2...)
In addition to decorative sewing pattern data for regular sewing patterns such as letters and patterns, the data includes multiple practical decorations in advance in stitch formats suitable for practical functions for each of multiple sewing pattern groups with different practical functions. Sewing patterns are determined, and a plurality of standard-sized practical decorative sewing pattern data created in correspondence with these practical decorative sewing patterns are stored. When forming a practical decorative sewing pattern, the user selects the desired practical decorative sewing pattern data from among a plurality of practical decorative sewing pattern data, loads it into the embroidery machine, and also prints the selected practical decorative sewing pattern by operating the keyboard KEY. Based on the sewing pattern data, you can uniformly expand or contract in the X and Y directions perpendicular to the cloth surface, or
You can create patterns from standard-sized practical decorative sewing pattern data by independently enlarging and reducing them in the direction and Y direction, or by inputting the required external dimensions in the X and Y directions on the cloth surface. Practical decorative sewing patterns can be formed by automatically setting the shape and size of the sewing machine. Next, the practical decorative sewing pattern formed as described above will be explained with reference to FIGS. 2 to 7. In FIG. 2, the serrations D of the garment are created by the stitches of a heart-shaped sewing pattern C. The stitch type is a plain weave style stitch in which multiple rows are sewn within the range of the heart-shaped sewing pattern, shifted in one arbitrary direction, and then multiple rows are sewn, shifted in a direction perpendicular to these sewing directions. . By creating the serrations D in this way, a more decorative effect is created than in the conventional method shown in Figures 8 and 9, and it can be positively incorporated as part of the clothing design. . Although not shown in this case,
Needless to say, when stitching the hooked parts, auxiliary cloth, paper, etc. are pasted to the back of the cloth. In FIGS. 3 to 5, practical decorative sewing patterns E, F, and G are examples of stitches of a diamond-shaped sewing pattern, and the stitch type is the same as that of FIG. 2. E is based on standard size practical decorative sewing pattern data, F is created by reducing the standard data in the X direction and expanding in the Y direction, G is created by expanding the standard data in the X direction However, it is formed by reducing the size in the Y direction. Standard data can be enlarged or reduced equally in the X and Y directions using the keyboard (KEY), and can be enlarged or reduced independently in the X and Y directions, as well as setting the shape and size of the pattern. , it is also possible to automatically set the external dimensions on the cloth surface in the X and Y directions by inputting them using a keyboard. In Figure 6, H is a practical decorative stitching pattern that has a buttonhole sewing function as a practical function, and the area around the buttonhole sewing part I is a decorative pattern that is formed into a heart shape overall by stitches as shown in the figure. It is equipped with J. In FIG. 7, K is a decorative buttonhole sewing pattern which is one of the practical decorative sewing patterns different from that shown in FIG. 6, which has a buttonhole sewing function as a practical function.

【effect】
