Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery data processing apparatus for processing embroidery data when embroidering is performed by an embroidery sewing machine, and a computer-readable recording medium storing an embroidery data processing program.

[0002]

2. Description of the Related Art Conventionally, when a plurality of figures are sequentially and sequentially sewn, as shown in FIG.
Is formed between the sewing end point Pea and the sewing start point Psb of the next figure B to be sewn. The transfer thread L is removed by the operator after the sewing is completed so as not to impair the beauty of the embroidery product. Here, depending on the sewing end point Pea, the sewing start point Psb, and the relative positional relationship between the graphic A and the graphic B, the jumping thread L may be sewn by the seam of the graphic B as shown by the dotted line in the drawing. The removal of the sewn jumping thread L requires cutting the jumping thread at the four points of entering scissors points C1, C2, C3, and C4, which is very troublesome. Therefore, as described in Japanese Patent Application Laid-Open No. 2-118154, as a relay point of a jumping thread formed between each figure, a figure which precedes in a sewing order from a plurality of relay candidate points predetermined around the figure. There has been proposed a method of selecting one of the relay points so that a stitch does not occur with respect to a jumping thread between a figure and a subsequent figure.

[0003]

However, in the method described in Japanese Patent Application Laid-Open No. Hei 2-118154,
A plurality of relay candidate points must be determined in advance around each figure, and the sewing order of the plurality of figures must be set in advance. It takes a great deal of effort to set the relay candidate points and the sewing order, and depending on the sewing order set by the operator, as shown in FIG. If there is a figure Z to be sewn after these figures X and Y, the jumping thread Lz is sewn, and the operation time for removing the jumping thread Lz cannot be saved. Further, the jumping yarn passing through the selected relay point is not necessarily the shortest, and there is a problem that the consumption of the yarn increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem. In the sewing order in which the jumping thread is not sewn, and in the sewing order, the jumping thread between successive figures is minimized.

The control device 2 includes a CPU 21 that performs various arithmetic processing described later, and a ROM 2 that stores a program that defines a procedure of processing related to embroidery data.
2. a logical operation circuit mainly composed of a RAM 23 for temporarily storing graphic data and work data;
The coordinate data of the set point that defines the figure is read from the hard disk 1 via the input I / F 24, and processing relating to embroidery data described later is performed, and the processing result is output to the output I / F 2
5, and outputs the created embroidery data to the floppy disk device 4 via the I / F 25.

The operation of the embroidery data processing apparatus will be described below with reference to FIG. 5, taking as an example a case where a plurality of figures as shown in FIG. 2 are formed by embroidery.

First, as shown in FIG. 2, the hard disk 1 has set points d1 to d for respectively defining the figures D, E, F, and G.
It is assumed that coordinate data of 3, e1 to e5, f1 to f3, and g1 to g4 are stored. Then, when the embroidery data processing program stored in the ROM 22 is started, first, in step 1 (steps are abbreviated as S hereinafter, the same applies hereinafter), the coordinate data of the set point is read from the hard disk 1, and It is stored in the RAM 23.

In S2, the figure to be sewn first is selected from the figures D, E, F and G. Here, for example, assuming that a figure including the leftmost set point among the set points of the figures D, E, F, and G is automatically selected as a figure to be sewn first, the figure F is first selected. This will be selected as the figure to be sewn.

Next, in S3, from the set points f1 to f3 of the figure F selected in S2, all other figures D, E,
Calculate the transfer yarn path to each of the set points d1 to d3, e1 to e5, and g1 to g4 of G. For example, the jumping yarn path from the set point f1 to d1 is calculated by obtaining a line segment connecting f1 and d1. In the same manner, all the transition yarn paths from each set point of the figure F to each set point of the figures D, E, and G are obtained.

Subsequently, in S4, a plurality of jumping yarn paths calculated in S3 are acquired in order of shorter length. Here, as shown in FIG. 3, first, a jumping yarn path L1 from the set point f2 of FIG. F, which is the shortest path, to the set point g4 of FIG. .

Then, in the next S5, it is determined whether or not the sewing of the jumping thread occurs in the jumping thread path L1 acquired in S4. Here, the jumping yarn path has an intersection with any one of a plurality of line segments forming each figure, and
If the graphic having the line segment forming the intersection is not yet connected to another graphic by the optimal jumping thread path, it is determined that the sewing of the jumping thread will occur. That is, the jumping yarn path L1 is a line segment connecting the set point d3 and the set point d1 (hereinafter, simply referred to as a line Min d3-d1
Called. The same applies hereinafter) and the line segment d2-d3. Therefore, in this case, it is determined that sewing will occur in the cross thread path L1.

In S5, if it is determined that sewing will occur, the flow returns to S4, and the next shortest transfer thread path L2 after the previous transfer thread path L1 obtained in S4 is obtained. Then, the process proceeds to S5, and it is determined whether or not sewing is performed on the cross thread path L2 acquired in S4. Since the jumping thread path L2 does not intersect with any of the plurality of line segments forming each figure, it is determined that the jumping thread does not sew on the jumping thread path L2. Therefore, the jumping yarn path L2 is selected as the optimum jumping yarn path connecting the graphic F and the graphic D.

If it is determined in S5 that sewing does not occur, the process proceeds to S6, where a plurality of figures D, E, F,
It is checked whether or not all of G have been connected to another figure by the optimal jumping thread path. Here, the graphics E and G are not yet connected to the other graphics by the optimal jumping yarn route just by determining the jumping yarn route L2.
4 and S5, the optimum jumping yarn path L2 selected
As a result, the graphic D determined to be sewn next to the graphic F selected in S2 is selected as the graphic to be sewn first, and the process returns to S3.

In S3, from the set points d1 to d3 of the graphic D selected in S7, the set points e1 to e1 of the graphics E and G for which the optimal jumping yarn path between the graphic D and another graphic has not yet been determined.
e5, calculating the jumping yarn path to g1 to g4.

Then, in S4, a plurality of jumping yarn paths calculated in S3 are acquired in order of decreasing length. Here, as shown in FIG. 4, a transfer thread path L3 from the set point d2 of the graphic D to the set point e1 of the graphic E is acquired.

Next, in S5, it is determined whether or not sewing will occur for the cross thread path L3 acquired in S4. Since the jumping thread path L3 does not intersect with any of the plurality of line segments that form each figure, it is determined that sewing will not occur in the jumping thread path L3. Therefore, figure D
Yarn path L as the optimum yarn path connecting the figure and the figure E
Select 3.

In the same manner, as shown in FIG. 4, the transfer yarn path L 4 is selected as the optimum transfer yarn path connecting the graphic E and the graphic G.
Is selected, the process proceeds to S6, and a plurality of figures D, E,
It is determined that all the figures F and G have been connected to other figures by the optimal jumping yarn route, and the process proceeds to S8, where the plurality of figures D, E, and
The shapes of F and G and a plurality of selected optimum yarn paths L2
L3 and L4 are output to the display 3.
