Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing machine embroidery device configured to sew an embroidery pattern on a material to be sewn.

[0002]

2. Description of the Related Art Conventionally, various embroidery devices for performing embroidery sewing of patterns are known in Japanese Patent Publication No. 4-55720 and the like. There is one in which an operator appropriately selects and performs embroidery sewing.

For example, as shown in FIG. 6, each of these patterns is divided into a plurality of parts (a), (c) and (d) and sewn in sequence to obtain a final embroidery pattern (a). It is designed to be used. When the sewing of one part is completed, the thread trimming operation is performed, and for example, the needle thread is replaced with a different color for color change, and then the sewing operation of the next part is started. In the example of FIG. 6, the number of parts is 3, and the number of times of color change stop or thread cutting operation is 2.

Sewing operation information when executing such embroidery sewing is usually the directory corresponding to each embroidery pattern,
The embroidery pattern is stored in advance in the sewing management information including a header and a table, and when the embroidery pattern is selected, the selected embroidery pattern and the sewing management information (sew order) are displayed on the display panel. Is configured.

[0005]

However, in such a conventional embroidery device, there is a restriction that the sewing order and the color change stop, that is, the thread trimming operation cannot be arbitrarily combined and set, which is unnecessary for the sewing work. There is a problem that it takes time, and the colors and shapes of the patterns cannot be combined in various ways, and the degree of freedom in embroidery sewing is low.

That is, when changing the order of stitches by changing the order of sewing, or changing the color of each part to the same color or a different color, depending on the combination of the sewing order and the color change, a plurality of parts may have the same color. Even though the thread can be continuously sewn without thread trimming, the thread trimming operation is always performed at the end of sewing of each part, and a wasteful waiting time may be required for sewing. Similarly, when one part is sewn with a certain color, another part is sewn and the other part is sewn, and then the original color is used again, an originally unnecessary color changing operation, that is, a thread cutting operation is performed. I have to.

Therefore, according to the present invention, the sewing order and the color changing stop, that is, the thread cutting operation can be arbitrarily and easily combined and set, and the set color and shape of the embroidery pattern can be sewn efficiently. It is an object of the present invention to provide a sewing machine embroidery device that is made possible.

[0008]

In order to achieve the above object, the present invention is to sew each part constituting an embroidery pattern in a predetermined color, and the thread is sewn at the end of sewing of each part. In a sewing machine embroidery device configured to perform a cutting operation, the sewing order of each part is determined based on the sewing color information specified for each part, and the thread cutting operation is performed for the same color parts. It has a configuration including an embroidery sewing control device configured to continuously perform sewing without the need for sewing.

[0009]

In the embroidery device having such a structure,
Based on the sewing color information designated for each part, the sewing order of each part and the execution / non-execution of the thread trimming operation of each part are set at the same time.
