For example, when it is designated that the thread mark is to be sewn at the two reference positions indicated by the display R in FIG. 3, as shown in FIG. 5, the unit pattern M at the bottom end is sewn. As shown by the dotted line in the drawing from the position P of the sewing needle to the position S on the shortest distance on the specified line 26, after drawing out the thread, the two threads at the selected reference position are traced on the specified line 26. By sewing the mark, it is possible to prevent the transition thread generated when sewing the thread mark from straddling the embroidery pattern M as much as possible. For this purpose, the position on the specified line 26 at the shortest distance from the position P of the sewing needle at the time when the embroidery pattern M has been sewn, that is, the position of the drawing point S, and the positions T and U where the thread mark is to be sewn. It is necessary to add sewing data indicating that the seam should be sewn to the corner positions K1 and K2 of the prescribed line 26.
At this time, in order to shorten the length of the crossover thread by setting the forward path following the specified line 26 in the clockwise direction or the counterclockwise direction, in which of the normal paths the length of the crossover thread is shortened. Therefore, it is necessary to obtain sewing data for sewing the position of the above-described drawing point S, the positions T and U where the thread mark is to be sewn, and the corner positions K1 and K2 of the specified line 26.

  This corresponds to the processing of adding sewing data for sewing the thread mark and the crossover thread to the position of the drawing point S, the positions T and U for sewing the thread mark, and the positions K1 and K2 at the corners of the specified line. The process by CPU21 based on a program is demonstrated based on the flowchart shown in FIG.

  First, in step S1, selection of the unit pattern M to be used for sewing is executed. In the following description, it is assumed that four unit patterns M are selected as shown in FIG. Next, in step S2, sewing data for sewing the selected unit pattern M is read. This sewing data is the position data of the needle drop point for sewing the pattern (in other words, the data corresponding to the feed amount of the embroidery frame by the moving means 4) and is stored in the storage disk 5 or the ROM 23. It is.

  Next, in step S3, a position to the effect that the thread mark is to be sewn is set. As described above, this setting is performed when the operator designates the thread mark position designation buttons 27 to 33 shown in FIG. In the next step S4, the position of the extraction point S is obtained. In the case shown in FIG. 5, the shortest position on the regulation line 26, that is, the drawing point S is obtained from the final position P of the sewing needle at the time when the lowermost unit pattern M has been sewn. In step S5, sewing data for sewing one stitch from the final position P of the sewing needle to the drawing point S (Xmin, Ymin), which is the shortest distance at the time when the bottom end unit pattern M has been sewn, is obtained. to add.

  Next, in step S6, by executing the thread stamp sewing route search subroutine shown in FIG. 7, all the thread marks (in the case of FIG. 5, in the case of FIG. In the case of sewing (positions T and U), it is determined whether the length of the crossover thread is shorter in the clockwise direction or the counterclockwise direction on the specified line 26. In this case, as shown in FIG. 7, in step S100, first, the coordinates of the aforementioned extraction point S are set to the current coordinates for search (Xcur, Ycur), and the total distance L1 from this extraction point S is set. Initialize to 0. Here, the current coordinates are coordinates indicating a search position for searching for a position set as a position for sewing the thread mark.

In step S101, when tracing the specified line 26 in the clockwise direction and finding the position set as the position for sewing the thread mark in step S102, the current coordinates (Xcur, Ycur) are set to (Xt, Yt), and the total distance from the above-mentioned drawing point A to the position of the thread mark is obtained. Here, (Xt, Yt) means coordinates set as a position for sewing the thread mark. Next, in step S104, when the sewing position of the thread mark found in step S102 is the position of the last thread mark set as the position for sewing the thread mark, in step S105, the above-described withdrawal point S is set. The total distance L1 from to the position of the last thread mark is obtained. On the other hand, if it is not the position of the last thread mark, the processes of steps S101 to S104 are repeated.

  Next, by executing the above-described processing from step S102 to step S105 along the route in the counterclockwise direction from the drawing point S, in step S106, the total distance L2 from the drawing point S to the position of the last thread mark is obtained. Ask. The coordinates are (Xu, Yu). Next, when the total distance L1 is smaller than the total distance L2 at step 107, the additional route of the thread stamp sewing data is set to the clockwise route at step 108, and the coordinates (Xt, Yt) are set to (XEND, YEND). Set to. On the other hand, if the total distance L1 is larger than the total distance L2 in step 107, the additional route of the thread seal sewing data is set to the counterclockwise route in step 109, and the coordinates (Xu, Yu) are set to (XEND, YEND). ). Through the above processing, the route of the additional route of the thread stamp sewing data is determined in the clockwise direction or the counterclockwise direction.

Next, returning to step S7 shown in FIG. 6, the reference line 26 is traced in the clockwise or counterclockwise route determined in the above-mentioned step S6, and the reference position where the thread mark is to be sewn is found in step S8. In step S9, position data and shape data (sewing data for sewing the aforementioned stitch Q) relating to the found thread mark are added as thread mark sewing data. If a position corresponding to the corner K of the rectangular regulation line 26 is found in step S10, a stitch for one stitch is moved from the sewing position of the thread mark to a position corresponding to the corner K in step S11. Add sewing data for sewing. If it is determined in step S12 that the position of the thread mark found in step S8 is not the last position among the positions to be sewn, the process returns to step S7. On the other hand, if it is determined in step S12 that the position of the thread mark found in step S8 is the last position among the positions to be sewn, the thread mark set by the sewing manufacturer is ended. In this manner, the sewing data indicating that the seam should be sewn is added to the position of the above-described drawing point S, the positions T and U where the thread mark is to be sewn, and the corners K1 and K2 of the specified line. . Specifically, the transition thread stitch extending from the withdrawal point S to the corner position K1 on the defined line 26, the transition thread stitch extending from the corner position K1 to the reference position T, the thread marking stitch Q at the reference position T, the reference Sewing data has been added for sewing the crossover stitch from the position T to the corner position K2, the crossover stitch from the corner position K2 to the reference position U, and the thread marking seam Q at the reference position U. become.

Next, the control unit 7 controls the sewing means 2 and the moving means 4 on the basis of the thread mark and the transition thread sewing data added as described above, and the position of the drawing point S and the reference for sewing the thread mark. Seams along the prescribed line 26 can be sewn at the positions T, U and the corners K1, K2 on the prescribed line 26. In this way, by determining the route connecting the reference position T for sewing the thread mark and the drawing point S, the crossover thread extending between the drawing point S and the above-mentioned corner position K1 extends along the prescribed line 26. Since it is sewn so as to cross, it is sewn so as not to straddle the unit pattern M. Further, by adding transition thread sewing data for sewing the corner position K2 after sewing the thread mark with respect to the reference position T, a transition thread crossing between the reference position T and the corner position K2, which is the thread mark sewing position, and The crossover thread extending over the corner position K2 and the reference position U that is the thread marking sewing position is also sewn so as not to straddle the unit pattern M.

According to the above-described process, after sewing the four unit patterns M, a thread mark is sewn at the reference position T shown in FIG. 5, the work cloth is temporarily detached from the embroidery frame 3, and the arrangement direction of the four unit patterns M By shifting the work cloth in the direction parallel to the (Y direction) and then sewing the unit pattern again according to the thread mark sewn at the reference position T with the sewing needle position of the embroidery sewing machine 1 being set. As shown in FIG. 8, the embroidery pattern M is sewn in a state of being arranged in a certain direction.
5 is set so as to sew the thread mark at the reference position K2 shown in FIG. 5, the work cloth is reset to the embroidery frame, and then the sewing of the unit pattern M is performed again by aligning the sewing needle with the position K2. By performing this, it becomes possible to sew a pattern arranged in a staircase pattern as shown in FIG.
Furthermore, a thread mark is sewed at the reference position U shown in FIG. 5, the direction of the selected unit pattern is rotated 90 degrees, and the work cloth is orthogonal to the arrangement direction of the unit pattern M that is initially set. As shown in FIG. 10, the direction is changed to the direction and the embroidery frame is set again, and then the sewing of the unit pattern M is resumed by adjusting the position of the sewing needle to the position of the thread mark sewn at the reference position U. The unit pattern M is sewn in a state where the arrangement directions are orthogonal to each other.
