Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pattern data creation device for a sewing machine that forms seams while moving a cloth holding frame on which a cloth is stretched in a two-dimensional plane. be.

[Prior Art] Conventionally, for example, in this type of embroidery sewing machine, embroidery is performed by reading data from a floppy disk into which data related to the sewing operation of the sewing machine, a program for controlling the X-Y direction movement of the support frame, etc. are input. The following two methods were adopted to embroidery patterns, particularly fixed marks, such as marks such as ○ and I. That is: 1 Each mark pattern “〇” is on the floppy disk.
By writing (inputting) and "I" separately, reading (recalling) each mark on the sewing machine, performing operations such as returning the character spacing, and sewing them separately, both marks can be created. Synthesize and complete ○I.

2 ○Enter the full Italian mark all at once, read it out once, and embroider it in the same process.

[Problems to be Solved by the Invention] However, in the conventional data input/retrieval methods as described above, each of the following problems occurs.
It had the following shortcomings. That is: 1 In the first method, the "〇" and "Italy" of each mark are created and stored as separate data, so if they are read out independently and in parallel by the sewing machine, each mark will be read out in parallel. Mark “〇”
It requires a jog operation to overlap “I” and “I”.
Not only is the operation complicated, but it is also difficult to maintain relative position accuracy during composition, which significantly reduces the productivity of the stitching work.

2 In addition, in the second method, since all marks are input at once, it is necessary to recreate the data each time the mark changes.
For example, when a large number of similar marks such as ○3 and ○water are required, a “〇” mark pattern is required each time, but since it is not possible to share and combine these marks, the efficiency of data input is extremely poor. It was.

The present invention has been made in view of the problems of the conventional input/output method as described above, and in addition to solving the above-mentioned drawbacks, this invention also enables fixed patterns to be freely combined/modified. The purpose is to provide a method for inputting seeds.

[Means for Solving the Problems] Therefore, in the present invention, means for matching the origin and baseline of one pattern with the origin and baseline of the other pattern, and matching the pattern pattern of the one pattern, are provided. and a second storage means for storing the result of the calculation based on the origin and base line of the other, and by combining and storing at least two different patterns, the object is achieved. This is what we are trying to achieve.

[Function] With the above configuration/method, it is possible to combine each pattern, which not only greatly saves input time when creating similar patterns, but also when combining them using operations on the embroidery sewing machine. The combination accuracy can be greatly improved compared to the above. Furthermore, it is possible to combine and modify existing patterns.

[Example] The present invention will be explained below based on examples.

FIG. 1 shows an example of an input pattern original according to the present invention.
FIG. 2 shows a schematic block diagram of the hardware configuration according to the method of the present invention, and FIG. 3 shows a flowchart of a complex pattern input operation sequence.

(Configuration) In Fig. 2, D is a digitizer (or tablet, coordinate reading device) connected to a cursor (reading device) (not shown) via a cord, and the input pattern original example shown in Fig. 1 is , place it on top of this and set it. F is a floppy disk system for writing basic data of input patterns, etc.
C is a CPU which is a control device for writing/reading data and other various calculations, and M ₁ , M ₂ and M ₃ are storage devices for pattern data.

On the other hand, although not particularly shown, the embroidery sewing machine device is placed on a base with a flat top surface, and is detachably mounted within a support frame whose movement is controlled in the X-Y directions by predetermined programming. The sewing machine is configured to embroider a work cloth that is stretched and held on a supported embroidery frame.

In FIG. 1, L ₁ indicates the base line 1, O ₁ indicates the origin 1, and A indicates the final point. Also. S on the pattern pattern indicates each needle movement line for stitching, and Sa indicates the understitch line (skip stitch line on the one-stroke drawing sequence with the sewing machine needle).

(motion) Next, the input operation will be explained.

1 In the case of a single pattern: In this case, as in the past, as shown in the example in Figure 1, the existing pattern data 1N ₁ is the X and Y coordinate value of each point based on the base line L ₁ and the origin O ₁ . input to the floppy disk.

2. In the case of a composite pattern (see Figure 3): The example in Figure 1 with the base line 1L ₁ , the origin 1O ₁ and the final point A is used as the existing basic data, and additional patterns, such as marks (baseline 2L ₂ ,
An example of adding and combining the origin 2O ₂ and the final point B) will be described.

First, at the start point, place the above additional pattern original on the digitizer D (Fig. 2).
Set. In step 1, enter the baseline 2L ₂ ,
In step 2, enter the origin 2O ₂ . next,
In step 3, the existing pattern data _1N1 is read out, and in step 4, the baseline 2
The base line 1L ₁ is aligned with L ₂ and the origin 1O ₁ is aligned with the origin 2O ₂ and stored in the memory 1M ₁ (FIG. 2), and these are set as data ND ₁ . Therefore, the origin 2O ₂ and base line 2L ₂ of the additional pattern coincide with the origin 1O ₁ and base line 1L ₁ of the existing pattern data 1N ₁ .

Then, in the fifth step, the necessity of another existing pattern is examined, and if necessary, the third and fourth steps are repeated. If it is not necessary, move on to the 6th step to consider whether or not to create new pattern data, and if necessary, input (or modify) additional patterns in the 7th step, and store the data in the memory.
Store in M ₂ (data 2N ₂ ). If it is not necessary, proceed to step 8.

In step 8, the CPUc performs pattern connection calculations. That is, (1) The position of the final point A (Fig. 1) of the existing pattern is
Calculate using the X and Y values from the origin _1O1 .

(2) Calculate the starting point B of the additional pattern using the X and Y values from the origin 1O ₁ (2O ₂ ).

(3) Calculate the position of point B as relative X and Y value data with respect to point A, and use it as the basting data 3N ₃ described above.

(4) Added pattern input data 2N ₂ to base line 1L ₁ ,
New data 4 (N ₄ ) is created by calculating from the origin 1O ₁ .

After the completion of the eighth step, in the ninth step, the data _1N1 , data _N3 and data _4N4 are connected and stored in the memory _3M3 as new pattern data _5N5 .

At step 10, finally Floppy disk F
Complete writing (input) to.

(Other Embodiments) Although the above operation has been described for the case where there are three memories, there is no problem even when there are two memories, M ₁ and M ₂ .In this case, the memory 1M ₁ that had stored data 1N ₁ All you have to do is write the new pattern data _5N5 to .

[Effects of the Invention] As explained above, according to the present invention, existing data that has been confirmed as an embroidery pattern can be used, so it is easy to modify the existing pattern by connecting an additional pattern in the middle. In addition, by combining multiple existing patterns, new patterns can be created without the need for input work, which greatly saves input man-hours and time when creating similar patterns. With this operation, we were able to significantly improve pattern accuracy compared to when compositing by restoring character spacing.
