Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an automatic 4Is machine controlled by a microcomputer that performs name embroidery, etc., and in particular has a function that allows confirmation of the sewing range including the sewing start point of a stitch pattern, and correction and confirmation of the position of the sewing range itself. This invention relates to an automatic embroidery machine equipped with an automatic embroidery machine.

[Prior art and problems to be solved by the invention] Originally,
The embroidery position and range of the character string are determined by arranging the characters from there, using the sewing start point as a reference. In the case of the "head stitching method", the sewing start point is the current needle drop point. In addition, in the case of the "centering sewing method", the starting point of the character string divided into two with the current needle drop point as the center becomes the sewing start point. As a conventional technique for checking the stitching range, there is a technique described in Japanese Patent Application No. 61-33791 filed by the same applicant as the present application. To summarize the prior art, when the start key is first operated, the embroidery mP? In this technique, the embroidery frame is moved to confirm the sewing area in order for the operator to recognize the sewing area for the embroidery frame while the vertical movement of the needle is stopped. However, according to this conventional technology, for example, when you want to finely adjust the positional relationship between the character string you are about to embroider and other marks, patterns, pictures, etc. that already exist, the entire process of checking the sewing range is performed. After the confirmation operation is completed, it is necessary to move and adjust the embroidery frame using the manual frame movement key and repeat the entire process of sewing area confirmation operation again to clarify the sewing area including the sewing start point and the position of the sewing area itself. There is,
Adjustment required a great deal of effort and time.

[Means for Solving the Problems and Effects of the Invention] The present invention provides a seam forming means, an embroidery frame, a driving means for driving the embroidery frame to change the relative position between the two, and an embroidery pattern. In an automatic embroidery machine, which stores a large number of pattern information groups and is equipped with an information storage means, and which moves an embroidery frame while stopping vertical movement of a needle to trace the outline range of a pattern group to check the sewing range. , a sewing range confirmation temporary stop means for stopping the sewing range confirmation operation midway through the sewing range confirmation operation; To provide an automatic embroidery machine having a position correction control means for changing the relative position with respect to a stopped stop point, and a correction calculation means for correcting the position of the entire sewing range based on the corrected movement amount of the stop point. According to the present invention, by temporarily stopping the embroidery frame during the sewing range confirmation operation and moving the embroidery frame manually, the sewing start point can be determined more quickly than before based on the amount of movement. This has the effect of correcting and confirming the position of the sewing range itself of the included character string. More specifically, for example, firstly, if you want to finely adjust the positional relationship between the character string you are about to embroider and other marks, patterns, pictures, etc. that already exist, you can There is an effect that the sewing range confirmation operation is temporarily stopped when the sewing machine approaches these marks, etc. that already exist before the entire process is completed, so that the positional relationship can be quickly fine-tuned. Secondly, if the range confirmation key is operated during a pause during the sewing range confirmation operation, the sewing range confirmation operation will be restarted from the needle drop point position, so the above-mentioned positional relationship can be fine-adjusted, etc. In this case, there is an effect that the mark or the like can be brought closer to the most preferable position for position correction. Thirdly, if you operate the clear key during a pause during the sewing range confirmation operation, the needle drop point will return to the starting point of the sewing range! With this, when the position correction is completed or when it turns out that there is no need for position correction during the sewing range checking operation of the character string, the sewing range checking operation can be quickly finished, and by these This function allows the position of the sewing range itself to be quickly corrected and confirmed.
