Abstract

PURPOSE:To enable a time to be remarkably shortened by specifying the direction of main stitching after a wave(waveform) area is set, and by generating stitching set almost orthogonally to a line for providing the input of the direction from a starting point to an end point, for wave processing. CONSTITUTION:After a wave area is set, the input of the starting point S and end point E of wave processing is provided through a mouse and is shifted to input in the wave progressing direction(dotted line), and input is provided by free linear line input. In this case, the wave signal direction is set to be of a thread density reference. After that, stitching is run at a stroke from the starting point S to the end E vertically to the wave signal direction. Besides, when the input of the starting point and the end point onto the area is provided, then input except onto the area line should not be provided, and so input within the radius of 1mm on an input point is contrived to be acceptable. This is in order to be unable to provide input to the same point.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wave processing method in an embroidery machine employing an area input system.

[Conventional technology and its problems]

Conventionally, when inputting a wave block, unlike a rectangle or a parallelogram, the x-wave block was divided into a number of blocks.

For example, in the case of a wave block as shown in Figure 1,
It was divided into 1 to 12 parts and inputted. This took a lot of effort, took a lot of time, and was inefficient.

On the other hand, the inventors of the present invention have developed a method and device for creating embroidery machine stitch data that can be input easily and with high precision on a computer display, eliminating the need for enlarged drawing work and digitizing manual labor by utilizing vector software. (Patent application Hei 2-9
No. 8567).

In other words, an image of the original embroidery drawing is input into a computer using a scanner, each original drawing line is thinned using the line drawing vector method, it is displayed as an image, and then the image data is imported as a bit image and one black dot is added. Extract one point, perform thin line processing from the cluster of extracted points, convert the extracted points into geometric values as continuous points, use the data converted to vectors as a sketch of the original embroidery pattern, and input the area. succeeded in developing an area system that

The present invention was invented under such circumstances.
For embroidery machines, there is no need to divide the waveform (waveform) area, and the conventional division input can be done all at once. The purpose is to provide a wave processing method.

[Structure of the invention]

In order to achieve the above object, the present invention inputs an image of an embroidery original pattern into a computer using a scanner, thins each original pattern line using a line drawing vector method, displays it as an image, and processes and processes the embroidery pattern. In an area system that divides parts into areas and registers areas according to the work order by inputting points of straight lines, arcs, and free curves according to the original drawing line, it is possible to specify the lock stitch direction after setting the wave area. The gist of this invention is to perform wave processing in an embroidery machine, which is characterized in that wave processing is performed by generating stitches substantially perpendicular to a line inputted in direction from a start point to an end point.

[Examples and effects]

In the wave processing of the method of the present invention, first, after setting the wave area, next, input the start point (S) and end point (E) of the wave processing with the mouse, move on to input the wave progress direction (dotted line), and Input by input (Figure 2). In this case, the wave traveling direction becomes the thread density standard.

Next, a stitch runs perpendicularly to the wave direction from the start point (S) to the end point (E).

Furthermore, when entering the start point or end point on the area, it must be entered somewhere other than on the area line, so as shown in Figure 4, inputs within a 1m radius of the input point are accepted. . This is because it is impossible to input at the same point.

FIG. 5 shows an automatic basting flowchart, and FIG. 6 is a flowchart showing the wave processing function.

First, when you come to the area where you want to perform wave processing.

Call the software. Next, input the area, and then input the wave direction (point input). At that time, the first
The point is the starting point and the final point is the end point. Next, a stitch is generated perpendicular to the line whose direction is input. This stitch generation is performed as follows.

■Calculate the line segment perpendicular to the straight line connecting points m and m+2 in the wave direction (Figure 7).

■Create sewing data perpendicular to the wave advancing direction (Figures 8 and 9).

For the area of the first block starting from the 8 points in FIG. 7, sewing data is created starting from the 8 points as shown in FIG. 8 and using parallel satin up to the AC side.

Next, stitching data is created using non-parallel satin while thinning out the AB to CD ratio and the thread density division of the wave advancing direction line.

〔Effect of the invention〕

As explained above, according to the wave processing method of the present invention, there is no need to divide the wave (wavy) area into inputs, and the stitches run perpendicularly to the wave direction to the end point all at once. Such batch processing saves the conventional effort and has a very large time-saving effect.
