Abstract

PURPOSE:To automatically prepare embroidery data for performing embroidery sewing along a seam capable of coping with the visible outline form of an embroidering zone on the basis of two partial visible outline forms as needle locations for a seam direction and an embroidering zone at both ends of the seam direction of the embroidering zone. CONSTITUTION:The whole of an embroidering zone is subjected to outer inversion judgement and inner segment judgement on the basis of the visible outline data thereof, and divided into partial embroidering zones where a seam direction is determined to be uniform. Furthermore, embroidery data is prepared in such a way as corresponding to a visible outline form, on the basis of two partial visible line forms as needle locations for a seam direction and the partial embroidering zone at both ends of the seam direction of each partial embroidering zone (processes S35 to S38). As a result, the seam of each partial embroidering zone does not change substantially about a boundary (division segment) between the adjacent partial embroidering zones.

A partial embroidery area data area 20c and an embroidery data area 20d for storing embroidery data are provided together with the working area 20e.

The data processing device 1 configured as described above
7 functions as a control device of the embroidery sewing machine 1 and, as will be described later, divides the embroidery figure into a plurality of partial embroidery areas in which the embroidery advancing direction is uniquely determined from the outline data defining the outer shape of the embroidery figure. It also functions as a dividing unit that calculates the contour line data of each partial embroidery region, and also functions as an embroidery data creating unit that creates embroidery data for each partial embroidery region based on the divided contour line data of the partial embroidery region. To do. Further, in this embodiment, the embroidery data is created in consideration of the shape of the external line segment that is the needle drop point of the partial embroidery area.

Hereinafter, for example, an embroidery figure A having a "tsu" shape as shown in FIG. 7 will be described as a specific example. The outline of the procedure for creating the embroidery data is as shown in the flowchart of the main routine shown in FIG. 1, and the flowchart of the subroutine is shown in detail in FIGS.

First, for example, when the user operates the keyboard 30 in a predetermined procedure, the floppy disk drive 3
2, the outline data of the embroidery figure A for which the embroidery data is to be created is read into the RAM 20 (step S1). Here, in the case of the embroidery figure A shown in FIG. 7, the outline (contour) is formed by connecting the 17 vertices P1 to P17 in order.
Is defined, so in this case the outline data is XY
It is composed of the coordinates of points P1 to P17 (hereinafter referred to as “constituent points”) represented by a two-dimensional coordinate system of axes.

In the next step S2, a process of dividing the embroidery figure A into a plurality of partial embroidery areas in which the sewing direction is uniquely determined is performed from the outline data. Details of this processing are as shown in FIG. That is, first, the outline data is stored in the divided stack 20b (step S21). Then, on the condition that the divided stack 20b is not empty (No in step S22), points Pxmax and Px having the maximum and minimum X coordinate values among the constituent points of the outline data.
min, and the point Pyma with the maximum and minimum Y coordinate values
x and Pymin are obtained (step S23). here,
In the example of FIG. 7, the point P6 is Pxmax and the point P1 is Pxmin.
The point P4 corresponds to Pymax and the point P9 corresponds to Pymin.

Next, the obtained points Pxmax and Px
The length of the line segment connecting min and the length of the line segment connecting the point Pymax and the point Pymin are compared (step S24), and if the line segment Pxmax-Pxmin is longer or equal (Yes). ), The point Pxmax is the MAX point, and the point Pxmin is the MI point
It is defined as N points (step S25). On the other hand, the line segment Pymax-
If Pymin is longer (No), set point Pymax to M
The AX point and the point Pymin are set as the MIN point (step S2).
6). In the example of FIG. 7, the point P7 is the MAX point and the point P2 is the MI point.
N points. By setting this MAX point and MIN point,
The embroidery advancing direction is determined, and in the example of FIG. 7, the embroidery advancing direction is the direction in which the line segment connecting the points P1 and P6 extends.

The M set by the above-mentioned setting method
When the line segment connecting the AX point or the MIN point and the constituent points of the contour line data adjacent to each other coincides with the line segment (division line segment) set when the embroidery figure is divided into partial embroidery areas. Is the midpoint of the line segment (dividing line segment)
Point or MIN point.

By setting the MAX point and the MIN point, the outline of the embroidery figure is divided into two partial outlines extending from the MAX point to the MIN point (step S2).
7). As a result, in the case of the embroidery figure A, the partial outlines P1-P2-P3-P4-P5-P6 and the partial outlines P1-P17-P16
-P15- P14- P13- P12- P11- P10- P9- P8- P7-
It is divided into P6.

Then, it is searched whether or not there is a point Pa that is flipped outward in each partial outline (step S).
28). Inverting outward here means M from the MAX point.
When connecting the constituent points of each partial outline to the IN point and from the MIN point to the MAX point,
This means refracting (reversing) in a direction (outward) away from a line segment connecting the MIN point and the MAX point in the direction opposite to the traveling direction. In the example of FIG. 7, when going from the MAX point to the MIN point, it is inverted outward at the point P12.
12 corresponds to the point Pa where it is inverted outward.

In this way, when the point Pa which is outwardly inverted is detected (Yes), a dividing line connecting the point Pa and the nearest constituent point on the traveling direction side of the partial contour line from the point Pa is set. By doing so, the embroidery figure is divided into two partial embroidery areas (step S29). In the example of FIG. 7, the point P1
The dividing line L1 (see FIG. 8) connecting the point 2 and the point P7 allows the embroidery figure A to be changed to the points P1-P2-P3-P4-P5-P6-P7-P12-P.
It is divided into two partial embroidery areas: an area R1 surrounded by 13- P14- P15- P16- P17 and an area R2 surrounded by points P7- P8- P9- P10- P11- P12.

In this way, when the embroidery graphic is divided into partial embroidery areas by detecting the above-mentioned outwardly inverted constituent points, the contour line data (coordinates of the constituent points constituting the contour) of each partial embroidery area is divided and stacked. It is stored in 20b (step S30).

The outline data of the partial embroidery area newly stored in the divided stack 20b is also searched for a point Pa that is outwardly inverted by the same procedure as described above, and the point Pa exists. If not (step S28
No.), the MAX point or the MIN point, and the constituent points of the contour line data of the partial embroidery area (hereinafter referred to as “inclusion determination point”).
And connect the line segments (hereinafter referred to as "inclusion determination line segments")
It is determined whether or not is included in the partial embroidery area (step S31).

When it is determined that the inclusion determination line segment is not included in the partial embroidery region (No), the inclusion determination line segment is extracted from the configuration points of the contour line data of the partial embroidery region adjacent to the inclusion determination point. Is located on the side of the partial embroidery area and is close to the MAX point or the MIN point (hereinafter referred to as “inclusive origin point”), and the internal origin point and the constituent point on the other partial outline that does not belong to the internal origin point Among them, the partial embroidery area is further finely divided by the line segment connecting the point closest to the inclusion origin point (hereinafter referred to as “inclusion destination point”) (step S32).

For example, in the partial embroidery area R1, MIN
Since a part of the line segment connecting the points P1 and P13 (inclusion determination line segment) exists outside the partial embroidery region R1, it is determined that the line segment is not included (No in step S31).
Then, the point P14 is the inclusion origin point and the point P4 is the inclusion destination point. As shown in FIG. 9, the line segment L2 connecting these two points causes the partial embroidery region R1 to further divide into the partial embroidery regions R3 and R4.
Is divided into Then, the outline data (coordinates of the constituent points forming the outline) of the partial embroidery regions R3 and R4 are stored in the divided stack 20b (step S3).
0).

When all the inclusion determination line segments connecting the MAX or MIN point and the inclusion determination point are included in the partial embroidery area in step S31, the minimum embroidery advancing direction of the partial embroidery area is uniquely determined. The outline data of the partial embroidery area is stored in the partial embroidery area data area 20c.

Such processing is performed until the divided stack 20b becomes empty (that is, until Yes in step S22).
To do. Thus, in the example of FIG. 7, the outline data of the partial embroidery areas R2, R3, and R4 described above is stored in the partial embroidery area data area 20c (step S33).

When the embroidery figure has been divided into a plurality of partial embroidery areas in which the embroidery advancing direction is uniquely determined, the process returns to step S3 in FIG. Embroidery data is created in consideration of the minute direction and the shape of the outline line segment that is the needle drop point of the partial embroidery area. Details of the procedure for creating the embroidery data are as shown in FIG. In the present embodiment, the partial embroidery region R4 divided by the above-described dividing procedure will be described as a specific example.

First, one of the outline data of the partial embroidery area stored in the partial embroidery area data area 20c is taken out (step S34). Then, a block division for dividing the partial embroidery area into blocks based on the direction of the dividing line segments at both ends of the embroidery advancing direction of the partial embroidery area, passing through the constituent points Ps of the outline data of the partial embroidery area. A line segment is set (step S35).

In the setting method, first, the direction defining lines of the dividing line segments at both ends in the embroidery advancing direction of the corresponding partial embroidery area are set as follows. That is, when the MIN point (or MAX point) that determines the embroidery advancing direction is a constituent point of the partial embroidery area as in the partial embroidery area R4 shown in FIG. 10, the embroidery passes through the MIN point (or MAX point). A straight line L3 perpendicular to the traveling direction is drawn, and this straight line L3 is
One end of the partial embroidery area in the embroidering direction (in this case, MIN
The direction defining line of the dividing line segment at the point).

On the other hand, when the MAX point (or MIN point) is a point on the outline line segment of the corresponding partial embroidery area (excluding the constituent points of the partial embroidery area), this MAX point (or MIN point) is set. An extension line L4 of the dividing line segment that passes is defined as a direction defining line of the dividing line segment.

Then, as shown in FIG. 11, an intersection O of the two direction defining lines L3 and L4 is obtained, and the intersection O and a constituent point Ps of the corresponding partial embroidery area (point P15 in this embodiment).
A straight line L5 passing through is set. An intersection point Pi between the straight line L5 and the other partial contour line that faces the partial contour line having the point Ps as a constituent point is obtained, and a line segment Ps connecting the point Ps and the point Pi is obtained.
Pi based on the direction of the dividing line segments at both ends in the embroidering direction,
A block division line segment PsPi for dividing the corresponding partial embroidery area into blocks.

Further, in the present embodiment, the corresponding partial embroidery area is defined based on the shape directions of the two partial outlines that pass through the constituent points Ps of the partial embroidery area and serve as the needle drop points of the corresponding partial embroidery area. A block dividing line segment for dividing into blocks is set (step S36). As the setting method, as shown in FIG. 12, first, a straight line Li passing through the constituent point Ps of the corresponding partial embroidery area and perpendicular to the embroidery traveling direction is drawn. Then, the intersection P of this straight line Li and the other partial outline
Find j.

Next, the shape direction on the straight line Li is set. With this setting method, as shown in FIG. 12, the constituent points Ps-1 (point P2 in this embodiment) and point Ps of the corresponding partial embroidery area are set.
+1 (point P3 in this embodiment) and straight lines M1 and M2 parallel to the straight line Li are drawn, and an intersection point Pj-1 and a point Pj + 1 between the straight lines M1 and M2 and the other partial contour line are obtained. .. Then, a combined vector of the vector Ps-1Ps + 1 and the vector Pj-1Pj + 1 is obtained, and the direction of this combined vector is set to the straight line Li.
In the shape direction.

Further, a straight line li is drawn which passes through the midpoint of the line segment PsPj connecting the constituent point Ps and the previously obtained point Pj and is perpendicular to the shape direction. An intersection Pk between this straight line li and the other partial outline is obtained. And this intersection P
A line segment PsPk connecting k and the point Ps is set as a block division line segment.

The two block dividing line segments PsPi and PsPk thus set are combined to set the final block dividing line segment at the constituent point Ps (step S).
37). As shown in FIG. 13, the setting method is to find a midpoint Pm between the end point Pi of the previously set block division line segment PsPi and the end point Pk of the block division line segment PsPk, and determine the midpoint Pm and the constituent point Ps. The connected line segment PsPm is the constituent point P
The final block division line segment PsPm in s.

Then, an area surrounded by the final block division line segment Ps-1Pm-1 at the configuration point Ps-1, the block division line segment PsPm at the configuration point Ps, and the four line segments of two partial external contour lines facing each other. 1 block. The four vertices Ps, Pm, Ps-1, Pm-1 of this block are stored in the embroidery data area 20d as block data which is embroidery data (step S38).

In this way, when the block data is stored in the embroidery data area 20d, it is judged whether or not there is an area which is not divided into blocks in the partial embroidery area (step S39). If there is a region that is not divided into blocks (Yes in step S39).
s), the process returns to step S33 to repeat the block data creation process, and when the creation of block data for all the partial embroidery areas is completed, the determination result in step S39 is No and this subroutine is completed.

When the process of creating the embroidery data (block data) for all the partial embroidery areas is completed, the process returns to the final step S4 of the main routine of FIG. The data is stored in a floppy disk (not shown) by the drive 32.

Since the embroidery data created as described above takes into consideration the direction of the dividing line segment when the embroidery figure is divided into a plurality of partial embroidery areas, the seams of the adjacent partial embroidery areas are the same. It does not change significantly across the boundary line (dividing line segment) and is aligned at almost the same seam.

Further, since the shape of the outline line segment which is the needle drop point of each partial embroidery area is also taken into consideration, the seams of each partial embroidery area are neatly aligned and each outline shape is finely supported. As a result, the embroidery pattern is well-balanced and looks good.

In the present embodiment, in addition to the direction of the dividing line segments at both ends of each divided embroidery area in the embroidery advancing direction, the shape of the external line segment that is the needle drop point of the partial embroidery area is also taken into consideration. Although the embroidery data is created, the embroidery data of each partial embroidery area may be created based only on the directions of the dividing line segments at both ends in the embroidery advancing direction of each of the divided partial embroidery areas.

Further, in the present embodiment, the contour line data of the embroidery figure A is read from the floppy disk drive 32, but the contour of the original drawing of the embroidery figure A is read as the contour line data by the image scanner 33. good.

In addition, in the present embodiment, the data processing device also has the function of the control device of the embroidery sewing machine, but it may be configured as a device for creating the embroidery data separately from the embroidery sewing machine. Various changes can be made without departing from the above.

[0056]

As is apparent from the above description, the present invention divides an embroidery figure into a plurality of partial embroidery areas in which the embroidery advancing direction is uniquely determined, and outline data of each of these partial embroidery areas and each partial embroidery area. Since the embroidery data is created in consideration of the directions of the dividing line segments at both ends of the embroidery advancing direction of the region, even if the stitches of each partial embroidery region are close to the boundary line (dividing line segment) between the adjacent partial embroidery regions. With the same stitch, the appearance of the embroidery pattern can be improved.

In this case, if the embroidery data is created in consideration of the shape of the external line segment that is the needle drop point of each partial embroidery area, not only the seams of each partial embroidery area are neatly aligned, but also each partial embroidery area. The region is filled with the seams that correspond to the contour line shape finely, and the appearance of the embroidery pattern can be further improved.
