DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery data creating system for creating embroidery data for forming embroidery on a cloth in a sewing machine, and more particularly, to sewing machine thread tension data corresponding to embroidery stitch types. The present invention relates to an embroidery data creating system attached to embroidery data.

[0002]

2. Description of the Related Art A thread tension mechanism in a sewing machine generally includes
By inserting the upper thread between the two disc members pressed by the spring and applying an appropriate tension to the upper thread, it is possible to prevent the extra upper thread from being drawn out against the lifting force of the upper thread by the balance. To form a good seam.

[0003] That is, if the pressing force of the upper thread by the both disc members is too small, the upper thread is unnecessarily fed out and a yarn tightening failure occurs. If the pressing force is too large, the upper thread becomes too tight. There is a possibility that the thread may break or the lower thread may be lifted upward to cause poor sewing condition.

For this reason, conventionally, Japanese Patent Publication No. 60-3815
As disclosed in Japanese Patent Publication No. 2 (KOKAI) No. 2, an automatic thread tension sewing machine for supplying a required length of upper thread for each stitch has been proposed. According to the automatic thread tension sewing machine described in this publication, an operator can automatically take an appropriate thread tension without being conscious of the cloth thickness and the type of seam, and can form a good seam.

[0005] By the way, the types of stitches include straight stitching,
There are various things such as zigzag sewing and folding sewing,
Japanese Patent No. 2540181 discloses a thread amount control device of an automatic thread feeding device in which the thread tension is changed according to the kind of the stitch and a good stitch is formed. According to the yarn amount control device described in this publication,
For example, by changing the equation for calculating the upper thread supply amount between straight stitching and zigzag stitching, a fine difference in thread tension is realized. That is, by inserting the instruction data corresponding to the linear stitching at the beginning of the linear stitching of the stored stitch data and inserting the instruction data corresponding to the zigzag stitching at the beginning of the zigzag sewing, the sewing machine can perform the following. The type of the stitch is recognized, and the arithmetic expression for the supply amount of the upper thread is made to correspond to the type of the stitch.

[0006]

In recent years, embroidery data is created by a computer, and the created embroidery data is stored on a floppy disk, or existing embroidery data is read from a floppy disk and transmitted to a sewing machine. An embroidery data creation system that forms an embroidery pattern based on the embroidery data is known.

The first stitch position 21 of the first pattern 21 is
The specified codes in A are [Jump] and [Thread tens
ion 2] is displayed. This [Thread tension 2] is a thread tension code, and the thread tension 2 in FIG.
This means folding sewing performed on the first pattern 21A. After reading the thread tension code, the computer 1 of the sewing machine computes a thread payout amount for folding and stitching the first pattern 21 using an arithmetic expression for the corresponding thread tension 2.

Next, the first stitch position 22A of the second pattern 22
[Thread tension 2] as thread tension 2 which is a thread tension code for straight stitching performed on the second pattern 22A is displayed as the designation code in. This is because the thread tensions of the folding sewing and the linear sewing both happen to be the thread tension 2. Then, after reading the thread tension code, the computer 1 of the sewing machine computes a thread payout amount for linearly sewing the second pattern 22 by using an arithmetic expression for the corresponding thread tension 2.

Further, the first stitch position 23A of the third pattern 23
[Thread tension 1] as thread tension 1 which is a thread tension code for zigzag stitching performed on the third pattern 23A is displayed as the designation code in.
After reading the thread tension code, the computer 1 of the sewing machine computes a thread feed-out amount for zigzag sewing the third pattern 23 by using an arithmetic expression for the corresponding thread tension 1.

As described above, according to the present embodiment, the thread payout corresponding to the type of the stitch of each of the patterns 21, 22, and 23 constituting the embroidery pattern 20 based on the sewing data inside the memory card 9 shown in FIG. Since the embroidery can be created according to the amount, an embroidery having a good seam can be formed.

Next, a case will be described in which an operator directly inputs a desired thread tension code at a specific needle drop point on the embroidery pattern 20 to perform embroidery.

For this purpose, a specific needle drop point 24 in the embroidery pattern 20 is designated in FIG. Next, when the icon 38 is clicked, a pop-up screen 39 appears. In the pop-up screen 39, icons 40, 41,
42 and other icons are described. Therefore, [Thread tension code 0
