Abstract

PURPOSE:To prevent the occurrence of a deviation between the inside of a figure and the control thereof, by making such embroidery data as the movement of embroidery is advanced while, by a data-arraying means, both stitches filling the figure and stitches along the contour are being alternately formed in each of a plurality of sections dividing the figure. CONSTITUTION:A data-arraying means rearranges and establishes the order of needle location points so that the movement of embroidery is advanced while both stitches filling the inside of a block 47 by a satin stitch and stitches along contour line elements, 1-3, 2-4 by a running stitch are being alternately formed in each stitch by the satin stitch, on the basis of filling-data and hemming-data. The stitches by the running stitch are formed so as to return to the point of one point before on the contour line element against the direction of advance. In this way, the order of needle locations becomes the following, i.e., 1 A B 1 B C A C D B D ...J 4 1 4, and even if a workpiece is shrunken by the formation of the stitches filling the figure, the stitch along the contour of a position corresponding to the shrinkage thereof is formed in the time when the shrinkage thereof is small.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a sewing machine that creates embroidery data that specifies each needle drop point in a sewing machine that embroiders a predetermined figure on a work cloth. The present invention relates to an embroidery data creation device.

(Prior Art) For example, in a sewing machine that embroiders one-point marks, etc., the control device of the sewing machine sequentially embroiders each needle drop point based on embroidery data that specifies a predetermined needle drop point corresponding to the shape. The sewing operation progresses by sequentially moving the work cloth or the sewing needle so that the needle falls. In this case, the embroidery data is automatically created by the embroidery data creation device.

This embroidery data creation device is configured with a microcomputer, an input device such as an image scanner or a keyboard, an external storage device, etc., and reads out pattern data stored in the external storage device, and uses the pattern data to create a needle drop. Points are automatically determined by calculation. -For example, as shown in Figure 10, the whole figure is divided into several blocks of rectangles or triangles,
For example, the vertices of one rectangular block a are set as points 1, 2, 3.4 in the direction of embroidery progress, and their positions (coordinates) are given as pattern data. For example, when performing satin stitching, line segments 1-3 and 2-4 (hereinafter referred to as contour line elements) are divided respectively based on the specified thread density, and the needle drop points A-J are determined. It will be done. Based on this embroidery data, the sewing needle points 1. A, B,...
...J.

They will fall in the order of 4, and the block a will be filled with satin stitches. Also,
When several blocks are consecutive, similar calculations are performed for the next block to create embroidery data, and embroidery operations are performed continuously based on this data.

(Problem to be Solved by the Invention) However, in the case of embroidery data that simply connects two contour line elements alternately as described above, the length of line segments 1-3 may be a line, for example, in a shape close to a triangle. If the length is sufficiently larger than the length of line segment 2-4, so-called thread breakage may occur on the side of line segment 1-3, resulting in an unsightly appearance.

In order to avoid such poor appearance due to thread breakage, it is conceivable to form a stitch that fills the inside of a predetermined figure, and then form a stitch along the outline of the figure using, for example, running stitches. According to this, the figure becomes bordered, so to speak, and the appearance of the finished product is improved.

However, with this method, when the satin stitch is applied to fill the inside of the shape and then the stitches are formed along the outline, the workpiece fabric may shrink in the direction in which the satin stitch extends. There was a risk that the needle drop point for sewing would not match the needle drop point for satin stitching. As a result, there will be a gap between the inside of the figure and the outline, creating a gap.
It becomes impossible to improve the appearance.

The present invention has been made in view of the above circumstances, and its purpose is to provide embroidery data that forms seams that frame the outline of a figure and prevents misalignment between the inside of the figure and the outline. An object of the present invention is to provide an embroidery data creation device for a sewing machine that can create embroidery data.

[Structure of the Invention] (Means for Solving the Problems) The embroidery data creation device for a sewing machine of the present invention creates embroidery data that specifies each needle drop point in a sewing machine that embroiders a predetermined figure on a workpiece cloth. a filling data calculation means for determining each needle drop point for forming a stitch that fills the shape; and a fill data calculating means for determining each needle drop point for forming a stitch along the outline of the shape. A border data calculation means, a seam that fills the figure based on the fill data obtained by the fill data calculation means and the border data obtained by the border data calculation means, and a seam that follows the outline of the figure. The embroidery apparatus is characterized in that it is provided with a data arrangement means for rearranging each data so that the embroidery operation progresses while being alternately formed for each of a plurality of sections divided into sections.

(Operation) According to the above means, the filling data calculating means can obtain filling data for forming a seam that fills out a figure, and the edging data calculating means can obtain filling data for forming a seam that follows the contour of the figure. You can get the border data. Then, using the data array means, the filling data and the edging data are created so that the embroidery operation progresses while stitches that fill the figure, stitches that follow the outline, and stitches that follow the outline of the figure are alternately formed for each of the plurality of sections that divide the figure. are rearranged and embroidery data is created.

In this case, seams that border the outline of the figure are formed on the work cloth based on the hemming data, so even if thread breaks occur in the seams that fill in the figure, the appearance will not deteriorate. Since the embroidery operation progresses while stitches that fill in the figure and stitches that follow the outline are formed alternately, even if the fabric shrinks due to the formation of stitches that fill in the figure, the shrinkage will be reduced. At a small point in time, a seam will be formed that follows the contour of the corresponding part. Therefore, misalignment between the inside of the figure and the outline is prevented as much as possible.

(Example) A first example of the present invention will be described below with reference to FIGS. 1 to 5.

First, the general structure of the embroidery sewing machine will be described with reference to FIG. The sewing machine main body 11 includes an arm section 13 integrally provided above a bed section 12, and a sewing machine table 1.
It is incorporated into 4. A needle bar 16 equipped with a sewing needle 15 is provided at the distal end of the arm portion 13, and the needle bar 16 is provided with a sewing needle 15.
A needle plate 17 having a needle hole (not shown) is provided above the needle bar 6 in correspondence with the needle bar]6. Although not shown in detail, the needle bar 16 is driven up and down by a sewing machine motor 8 (see FIG. 3) via a needle bar drive mechanism, and the needle plate is provided in the bed portion 12. A hook mechanism provided below 17 is driven by the sewing machine motor 18 in synchronization with the needle bar 16.

An embroidery frame 19 for holding a work cloth (not shown) is provided on the sewing machine table 14.

This embroidery frame 19 includes an annular outer frame 19a and an outer frame 19.
An annular inner frame 19b that removably fits into the inner circumference of a.
By fitting the inner frame 19b into the outer frame 19a so as to sandwich the work cloth therebetween, the work cloth is held in a stretched state within the inner frame 19b. The embroidery frame 19 can be freely moved horizontally on the sewing machine table 14 by a horizontal movement mechanism 20, which will be described below.

That is, the slide plate portion 19c integrally provided with the outer frame 19a is slidably attached to two slide bars 23 and 24 provided between the support stands 21 and 22. One support stand 21 is a sewing machine table 1.
A feed screw 27 extends between the motor mounts 25, 26 mounted on the slider 23, 24 in a direction perpendicular to the slider 23, 24. This feed screw 27 is rotatably driven by an X-transport remoter 28 attached to the motor mounting base 25, and is thereby integrated with the support bases 21, 22, etc. by the drive of the X-axis feed motor 28. Specifically, the embroidery frame 19 is moved in the X-axis direction. A rotation transmission shaft 30 is provided between the motor mount 25 and the motor mount 26 and is rotationally driven by a Y transport remoter 29 attached to the motor mount 26.

This rotation transmission shaft 30 is adapted to drive a wire 31.31 stretched between the support stands 21.22,
This wire 31. ．． The slide plate portion 19c is fixed to a midway portion of 31. With this, Y transport motor 2
9, the embroidery frame 19 is moved in the Y-axis direction. Horizontal movement mechanism 20 configured in this way
As a result, the work cloth set in the embroidery frame 19 is moved to an arbitrary position on the sewing machine table 14.

The embroidery sewing machine configured as described above is controlled by a control device 32. As shown in FIG. 3, this control device 32 includes a CPU 33, a ROM 34. R.A.
The main body is a microcomputer consisting of M35 and a bus 36 that interconnects them, and further, an input interface 37 and an output interface 38 are connected to the bus 36. The output interface 38 includes the sewing machine motor 18° and the X-axis feed motor 28. Motor drive circuits 39, 40, and 41 are connected to drive the Y transport motors 29, respectively. With this, the control device 32 controls the sewing machine motor 18°, the transport remoter 28. By controlling the Y transport remoter 29 and driving the needle bar 16 up and down while moving the work cloth using the horizontal movement mechanism 20, a predetermined embroidery on the work cloth is automatically executed. Further, a display drive circuit 43 for driving a display device 42 is connected to the output interface 38, and a keyboard 44. An external storage device 45 and an image storage device 46 are connected.

The control device 32 has a function as an embroidery data creation device, and creates embroidery data that specifies each needle drop point when embroidering a predetermined figure on a work cloth. To create this embroidery data, pattern data that defines the figure is required as described later, but the external storage device 45 stores in advance pattern data regarding a plurality of figures such as kana, alpha heads, numbers, etc. Furthermore, pattern data regarding newly created figures by the operator using the image scanner 46 can be input into the control device 32, and furthermore, this can be stored in the external storage device 45. There is. Further, the display device 42 displays on the screen a figure to be embroidered based on the pattern data.

Here, the pattern data will be briefly described.

Although not shown, if the figure is a circle, this pattern data includes the coordinates of three arbitrary points on the circumference and data indicating that it is a circle. Further, in the case of a circular shape, it includes the coordinates of three arbitrary points on the outer circumference, the coordinates of one arbitrary point on the inner circumference, and data indicating that it is a circular ring. In the case of a triangle or a quadrilateral, it includes the coordinates of the start and end points of the contour line elements that define the contour, data indicating that these contour line elements are straight lines, and embroidery progress direction data.

At this time, if the figure is relatively complex, the figure is divided into multiple blocks of rectangles or triangles (including sectors) that are continuous in the direction in which the figure extends, and each block has a pattern. Data is set. To give a specific example, as shown in FIG. 4(a), if the block 47 to be embroidered is a rectangle, the coordinates of its four vertices are 1,
It is stored with a number of 2°3.4. This number is
Point No. 1 is set to be the start of sewing, point No. 4 is set to be the end of sewing, and line segments 1-3 and 2-4 are contour line elements, and these line segments 1-3 and Sewing is set to progress in the direction of the arrow by stitches that alternately connect line segments 2-4. Further, when the block 48 is a triangle, two numbers are attached to one of the three vertices, as shown in FIG. 5(a). For example, 2 at one vertex
, 4, line segment 1-3 and vertex 2 (
Sewing progresses by stitches that alternately connect between 4) and 4).

Now, the control device ft32 creates embroidery data from the pattern data, and at this time, its software configuration performs fill data calculation to find each needle drop point to form a stitch that fills the figure. and a edging data calculation means for calculating each needle drop point for forming a stitch along the outline of a figure, and a stitch for filling out the figure and a stitch along the outline based on the filling data and the edging data. It is designed to realize a function as a data arrangement means for rearranging each data so that the embroidery operation progresses while being alternately formed for each of a plurality of sections that divide a figure. The functions of each of these means will become clear from the flowchart for creating embroidery data shown in FIG. 1, which will be described later. In this example, satin stitches are used as stitches that fill in the figure, and running stitches are used as stitches that follow the outline of the figure.Here, the needle drop point of these satin stitches and the needle of the running stitch are The falling point is now the same.

Next, the operation of the above configuration will be explained.

For example, when a figure for which pattern data has already been created is specified by operating the keyboard 44, the pattern data corresponding to that figure is read out from the external storage device 45 and stored in the RAM.
35. The embroidery data is created according to the flowchart shown in FIG. In addition, at this time, RAM35
The number of pattern data related to the figure for which embroidery data is created (or the number of blocks if it is divided into blocks)
is stored as N.

That is, first, in step S1, the count value P of the counter is increased by one. This count value P specifies the pattern data for which embroidery data is to be created (if the figure is divided into blocks, the pattern data of that block), and is cleared in the initial settings of the main program and is not used in step S1. When executed for the first time 1
becomes.

In step S2, the pattern data specified by the count value P is read out from the N pieces of pattern data, and in the next step S3, it is determined whether the figure related to the pattern data is a quadrilateral or a triangle.

Now, for example, if the first block 47 is a square, in the next step S4, one stitch development of the figure, that is, calculation of a specific needle drop point is performed. In this needle development, the needle drop points on the contour line elements 1-3 and 2-4 are determined so that the block 47 is filled with satin stitching of a predetermined thread density. The thread density is specified, for example, by the number of stitches crossing the line segment connecting the midpoint of line segment 1-2 and the midpoint of line segment 3-4, such as 5/1.

To find the needle drop point, as shown in FIG. 4(b), if the number of stitches M in the block 47 is 11, the outline elements 1-3 and 2-4 are each divided into 11 equal parts, The coordinates of every other point A-J are determined so that the vertex No. 4 is the starting point of sewing and the vertex No. 4 is the ending point. With this, sewing needle 1
5 is point 1. A.

Filling data for the satin stitch that fills the block 47 in the order of B, . . ., J, and 4 is obtained. Further, in this embodiment, as described above, running stitches along contour line elements 1-3 and 2-4 are used as stitches along the outline of the figure, so point 1. A.

The coordinates of B, . . ., J, and 4 become the border data as they are.

In the next step S5, the value of the counter value Q is incremented by one. This counter value Q counts the number of satin stitches based on the filled data, and is cleared in the initial settings of the main program. Next step S
In Step 6, the needle drop point that will be dropped after the formation of the Q-th stitch in the filled data is set, and the subsequent step S
In 7, the order in which sewing needles] 5 fall is set at each needle drop point.

Here, based on the above-mentioned filling data and edging data (the coordinates of the needle drop point are the same as the filling data), the stitches and contour line elements 1-
The needle drop point order is rearranged and set so that the embroidery operation progresses while running stitches along lines 3 and 2-4 are formed alternately for each satin stitch. Furthermore, the running stitches are formed so as to return to the previous point in the outline element in the direction of movement. Therefore, as shown in FIG. 4(C),
The next point after point B is set to the previous point 1, and in the case of satin stitch only, the needle drops are done in the order of A-B-C, but here, after point B, the needle drops back to point 1 and then continues. The process returns to point B again, and the order of A→B-1-B-C is set. Setting the needle drop order like this is
This is performed for each stitch in turn while incrementing by 1 (No in step S8). Note that since there is no point to return to at point 1 and point A, running stitch data is not inserted here. When the setting is completed up to the last point K, Q-
11, the result is Yes in step S8, Q is cleared (step S9), and the creation of the embroidery data in that block 47 is completed. With this, the needle drop order is 1
→A→B -1→B→C-4A→C→D→B groan D→...
...J → 4 → I → 4, and when embroidery is executed using this embroidery data, the stitch is a satin stitch in the block 47 as shown in FIG. 4(d). The outline will be bordered by running stitches.

On the other hand, even if the figure (block 48) is a triangle in step S3, one stitch is developed in step SIO. For example, when two numbers 2°4 are attached to one vertex, As shown in FIG. 5(b), filling data is obtained for filling the block 48 by satin stitching that alternately connects the contour line elements 1-3 and the vertices 2 (4). In this -needle expansion, the contour line elements 1-3 are similarly divided into equal parts according to the thread density, and the coordinates of points A-F are determined. B
, 2 . . . . . . F, filling data for the satin stitch that fills the block in the order of 2 is required. And here again, point 1. A.

B...The coordinates of F become the edging data as they are.

In the next step S11, which of the contour line elements 1-3 and 2-4 is longer is determined and stored, and in the subsequent step S12. S14. In S15, the above-mentioned step S5. S6. Similar to S7, the needle drop order is set so that the embroidery operation progresses while satin stitches and running stitches are formed alternately. Since there is no need to form a border stitch on the line element 2-4, when the answer in step 813 is NO, the needle drop point for the running stitch is not set. When the settings have been made up to the last point F, step 51
6 is Yes, clearing Q (step S9)
The creation of embroidery data in block 48 is completed. With this, the needle drop order is as shown in Fig. 5(c), point 1-2→A→1→A→2→B→A-B...
2→F→E-F-2, and when embroidery is executed using this embroidery data, the stitches are filled with satin stitches in the block 48, as shown in FIG. 5(d). The contour line elements 1-3 are crushed and bordered by running stitches.

When the above-described embroidery data settings are performed for all pattern data (Yes in step S17), the value of counter P is cleared (step 818), and the creation of embroidery data is completed. Thereafter, based on this embroidery data, the control device 32 controls each mechanism of the sewing machine to execute embroidery on the work cloth.

In this case, satin stitches are formed on the workpiece cloth based on the filling data, and stitches are also formed to frame the outline of the figure based on the edging data. Even if cracks may occur, the appearance will not deteriorate. Then, as the embroidery operation progresses, stitches that fill in the figure and stitches that follow the outline are formed alternately.
Even if the fabric shrinks due to the formation of a seam that fills the shape, a seam that follows the contour of the corresponding part will be formed when the shrinkage is small, and as a result, the inside of the shape and the contour There will be no discrepancy between the two.

In this way, according to the present embodiment, a seam is formed along the outline of the figure by running stitches based on the hemming data, so it is possible to prevent deterioration of the appearance due to so-called thread breakage. The appearance of the finished embroidery can be improved. Then, for each satin stitch, a running stitch is used to form a stitch that follows the outline.
Unlike the conventional method, which forms a stitch that fills the inside of a predetermined shape and then forms a seam that follows the outline of that shape, even if the processed fabric may shrink due to satin stitching, It is possible to prevent gaps from forming between the seams that fill in the figure and the seams that border the outline, and as a result,
It is possible to perform embroidery with an extremely good appearance.

In the above embodiment, the running stitch is performed by returning to the previous point such as point B-1-B, but when point D-1→
You can go back two points like D, or go one point ahead like point 1-B→1, or you can insert a running stitch every second or third point. There are various modifications to the way to form running stitches, such as setting different points on the outline element as border data and performing running stitches. is possible.

Next, regarding the second embodiment of the present invention, FIGS.
This will be explained with reference to the figures. Note that the same parts as in the first embodiment are given the same reference numerals, new illustrations and detailed explanations are omitted, and only important points will be described below.

This embodiment differs from the first embodiment in that a zigzag stitch is used instead of a running stitch as the stitch that follows the contour of the figure. In this zigzag stitch, stitches are formed that alternately connect both sides of contour line elements 1 to 3 and 2-4 along the contour line elements, as shown in FIG. 9(f). It is. Further, as the stitches for filling out the figure, satin stitches are used as in the first embodiment.

In this embodiment, the control device 32 creates embroidery data according to the flowcharts in FIGS. 6 and 7.

First, in step 521, the pattern data of the figure is read out, and in step S22, the number of pattern data, here the number N of block data, is stored. Here, for example, the figure 51
The blocks 51a have a piece-like shape as shown in FIG. 8, and are three rectangular blocks 51a.

If it is divided into 51b and 51c, it becomes N-3. In the next step 523, the count value P of the counter
is set to 1, and in the next step S24, one stitch development of the P-th, ie, the first block 51H is performed. In FIGS. 8 and 9, the embroidery progresses from left to right, so the block 51a closest to the person is the first. This -needle deployment is performed in the block 51 in the same way as in the first embodiment above.
Points along the contour line elements 1-3 and 2-4 are found so that a is filled with satin stitching of a prespecified thread density.

Then, in the next step S25, the block 51a
A judgment is made as to whether it is the end of sewing, point 3 or point 4. Now, the 9th
As shown in FIG. 7A, when the sewing end is at point 3, the process proceeds to subroutine A shown in FIG. 7 in step S26. In this subroutine A, first, step 5101
Then, the needle drop point by running stitch from point 3 to point 1 is determined (see FIG. 9(b)). Next step 81
In steps 02 to 5104, needle drop points for zigzag stitching for contour line element 1-3 are determined. To find the needle drop point of this zigzag stitch, first, in step 5102, as shown in FIG. , 6, 7.8 coordinates are determined.

In step 8103, the needle drop point for moving from point 1 to point 5 is determined. Then, in the next step 5104, one stitch is developed as in the case of satin stitching, and the point 5
．． 6,7. Each needle drop point forming a stitch that fills the block 52 defined by 8 is determined (see FIG. 9 (
d)).

Thereafter, in step 5105, the needle drop point for returning to point 3 from the sewing end point (point 7 or point 8) of the -needle expansion is determined, and subroutine A is exited. In the next step S27, the needle drop point from point 3 to point 4 is determined (see FIG. 9(e)), and in the next step 5
At step 28, the program proceeds to subroutine B in FIG. In this subroutine B, as in the subroutine A, the contour line element 2
The needle drop point for the zigzag stitch for -4 is determined.

That is, in step 5111, the needle drop point by running stitch from point 4 to point 2 is determined, and in step 5112
In step 8113, the coordinates of the vertices defining a block of a predetermined width centered on the outline element 2-4 are determined, and in step 8113, the needle drop point from point 2 to the starting point of the block is determined. Then, in the next step 5114,
- Each needle drop point forming a stitch that fills the block after needle development is determined (see FIG. 9(f)), and in step 5115, point 4 is determined from the sewing end point of the needle development described above.
The needle drop point for returning to is determined, and subroutine B is exited.

On the other hand, if the sewing end point is point 4 in step S25, subroutine B is first processed in step S29, and the needle is first used for zigzag stitching on outline element 2-4. After the needle drop point is determined and the needle drop point from point 4 to point 3 is determined (step 530), the process of subroutine A is performed in step S31 to perform zigzag stitching on contour line elements 1-3. Needle drop points are now required.

In this way, the embroidery data regarding the first block 51a is obtained. In the next step S32, the counter P
After the value of is incremented by 1 and the sewing start point of the next block 51b is set (step 534), embroidery data for the second block 51b is obtained in the same manner as described above. Such processing is carried out in three blocks 51a, 51b, 51
When the process is completed for c, the answer is NO in step 533, and the creation of embroidery data for the entire figure 51 is completed.

According to this embroidery data, the first block 51a
After a satin-stitch filled stitch is formed on the inside of the block 51a, a zigzag stitched edging stitch is formed along the outline of the block 51a, and then a filled stitch of the second block 51b is formed. is formed, and then the edging seam of the block 51b is formed.The embroidery operation is performed while stitches that fill the figure and stitches that follow the outline are formed alternately for each block that divides the figure 51. is progressing.

In this embodiment as well, as in the first embodiment, seams are formed along the outline of the figure based on the border data, so deterioration in appearance due to so-called thread breakage is prevented. The appearance of the finished embroidery can be improved. Then, I created stitches that followed the contours of each block using zigzag stitches, so
Unlike the conventional method, which forms a stitch that fills the inside of a predetermined shape and then forms a seam that follows the outline of that shape, even if the processed fabric may shrink due to satin stitching, It is possible to prevent gaps from forming between the seams that fill in the figure and the seams that border the outline, and as a result,
It is possible to perform embroidery with an extremely good appearance.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the stitches that fill in the figure may be formed by folding stitches, etc., without departing from the scope of the invention. Various modifications are possible.

[Effects of the Invention] As is clear from the above explanation, according to the embroidery data creation device for a sewing machine of the present invention, the filling data obtained by the filling data calculating means and the edging obtained by the edging data calculating means Based on the data, the data array means creates embroidery data such that the embroidery operation progresses while stitches that fill the figure and stitches that follow the outline are alternately formed in each of the multiple sections that divide the figure. Therefore, it forms a seam that borders the outline of the figure, and has the excellent effect of creating embroidery data that can prevent misalignment between the inside of the figure and the outline. be.
