Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lace embroidery machine having a function of embroidering by combining a plurality of pattern data.

〓Summary of the Invention〓 A plurality of pattern data, each of which is attached with a pattern data identifier, as a unit of stitching, is set and stored in advance, and by inputting and setting a series of ordered pattern data identifiers, a series of pattern data can be set when stitching. This is a lace embroidery machine that automatically embroiders by continuously reading the pattern data corresponding to the pattern data identifier, and reads out the pattern data corresponding to the pattern data identifier continuously and embroiders automatically. By using it in combination with , it is possible to perform embroidery using any combination of multiple handles.

〓Conventional technology〓 A lace embroidery machine that operates based on pattern data signals read from tapes, cards, etc. can embroider the same pattern repeatedly, reverse the pattern vertically or horizontally, or stitch different patterns. When stitching together, there is a method of rewinding or replacing the tape each time one pattern is finished, but with this method, you can check the end of each pattern, rewind or replace, and start. Preparatory work such as prior confirmation took time and work efficiency was extremely poor.

In order to improve work efficiency, there is a method of attaching tape, etc. for the number of times the stitching pattern is repeated or for the number of patterns to be combined, but it takes time to make the tape and the length of the tape becomes enormous. ,
The disadvantage was that it required a larger memory capacity for the embroidery machine.

Furthermore, when attempting to embroidery by reversing the embroidery pattern vertically or horizontally, existing tape or the like cannot be used and a new tape or the like must be created, resulting in the same drawbacks as mentioned above.

〓Problems to be Solved by the Invention〓 The purpose of the present invention is to improve the drawbacks of the above-mentioned conventional devices, and to provide a lace embroidery machine that has the function of embroidering by appropriately combining a plurality of embroidery handles. It is to provide.

<Means for Solving the Problems> In order to achieve the above object, the lace embroidery machine of the present invention includes a first storage means for storing a plurality of pattern data, each of which has a pattern data identifier attached thereto, and an ordered storage device. a second storage means for storing a series of pattern data identifiers stored in the second storage means, and a processing means for continuously reading pattern data corresponding to the pattern data identifiers stored in the second storage means from the first storage means, The pattern data set in advance and stored in the first storage means is continuously read out by the processing means in accordance with the pattern data identifier set in advance and stored in the second storage means, and the stitching is automatically performed. .

In addition, a polarity reversal symbol, number of repetitions, etc. are attached to each of the series of pattern data identifiers, and furthermore,
A start symbol, an end symbol, and the number of repetitions are inserted before and after multiple pattern data identifiers.

〓Effect〓 By doing this, when stabbing,
The pattern data stored in the first storage means is appropriately combined according to a series of pattern data identifiers stored in the second storage means, and stitching is automatically performed.

〓Example〓 An example of the present invention will be described with reference to the drawings.

Figure 1 shows the overall block diagram of the machine, which consists of a central processing unit that creates the embroidery machine drive signal, first and second storage units, a tape input unit, a key input unit, and a display consisting of a CRT. , drive control section, etc. are connected to it.

The central processing unit stores the pattern data inputted from the tape input unit and the series of pattern data identifiers inputted from the key input unit into first and second memory disks consisting of RAM, floppy disk, hard disk, etc.
The signals are stored in a storage section, and when the stabilizing machine is driven, these signals are sequentially read out from the first and second storage sections to create a stabbing machine drive signal.

The tape input section is for external storage means such as tape, card, floppy disk, etc.
The pattern data, which is a unit of stitching, is input from the CAD device to the central processing unit.

In addition, the key input section inputs a series of pattern data identifiers that determine the setting of pattern data identifiers and the arrangement of pattern data, a polarity reversal symbol, two types of repetition times,
Input settings such as start symbol and end symbol.

As shown in FIG. 2, the first storage section stores a plurality of pattern data each having a pattern data identifier, and the second storage section stores a plurality of pattern data, each with a pattern data identifier, as shown in FIG. A series of pattern data identifiers and auxiliary symbols are stored that determine the arrangement of each pattern data at the time of delivery.

The lace embroidery machine main body consisting of a servo drive is connected to the drive control section, and the drive control section drives and controls the lace embroidery machine main body based on the embroidery machine drive signal output from the central processing section to move the embroidery frame,
Performs operation/pause of the needle, borer, borer regulation, thread tightening and shuttle, rotation control of the main shaft, etc.

Next, the operation of the central processing section will be explained. The operation is roughly divided into the following three stages.

Reading the pattern data that becomes the stitching unit,
Register the pattern data identifier and store it in the first storage unit.

Reading a series of pattern data identifiers and auxiliary symbols and storing them in the second storage unit.

Execution processing when stabbing.

As shown in the flowchart in Figure 4, the operation is to attach different pattern data identifiers to all the pattern data that is the stitching unit read from the input section such as the tape (make sure that there are no duplicates). ) Store it in the first storage unit.

The operation is as shown in Fig. 3, by operating the key input section while looking at the display section, arrange the pattern data identifiers corresponding to each pattern data to be stitched in the order of stitching, and select each pattern data. polarity reversal symbol, (two types of) number of repetitions, start symbol,
After setting the end symbol, etc., the data is stored in the second storage unit.

Note that these series of pattern data identifiers may be input from an external storage medium through an input unit such as a tape.

Figures 2 and 3 show examples of data stored in the first and second storage units by operations, respectively, and the symbols in the left column of the figure
M2 is a polarity reversal symbol that reverses the polarity of each stitch in the pattern data in the direction of frame movement. There are other polarity reversal symbols that reverse the vertical polarity, and horizontal reversal and vertical reversal can also be used together.

Also, S and E in the right column are a start symbol and an end symbol, and in order to repeat the pattern data corresponding to multiple pattern data identifiers sandwiched by these two symbols for the number of repetitions specified on the left side of the start symbol S. belongs to.

It is also possible to further repeat a series of pattern data identifiers including S and E a specified number of times by sandwiching them between S and E.

Further, for example, data consisting of a series of pattern data identifiers as shown in FIG. 3 may be expressed by one pattern data identifier.

The operations are performed according to the sequence shown in FIG. For example, taking the pattern shown in FIG. 3 as an example, a series of pattern data identifiers are read out from the second storage section, and the first pattern data identifier A to be stitched is stored in the first storage section. The data is read from and output to the drive control section.

When the embroidery pattern A is completed, the second embroidery pattern C is read out from the first storage section, its polarity is reversed horizontally and output, and then the third embroidery pattern D is output.
Then, the combination of the embroidery pattern C (with its polarity reversed) and the embroidery pattern D sandwiched between the start symbol S and the end symbol E is output three times in total, and finally the embroidery pattern is output. Output pattern B.

Therefore, if embroidery is performed according to the pattern shown in FIG. 3, the patterns will be embroidered in the order shown in FIG.

Note that a plurality of sets of a series of pattern data identifiers and auxiliary symbols (each with a different program number) may be stored in the second storage section, and any one of them may be used as necessary.

In addition, the lace embroidery machine to which the present invention is applied is
Not only a servo drive machine, but also a mechanical card machine equipped with a device for electrically controlling the selection board (see, for example, Japanese Patent Application Laid-Open No. 59-47465) can be used.

〓Effects of the Invention〓 As explained above, the lace embroidery machine of the present invention converts pattern data, which is a embroidery unit, stored in the first storage means into a series of pattern data identifiers stored in the second storage means. Therefore, it is possible to perform stitching with any combination of patterns, and it is easy to operate, and there is no need to create a long tape every time the combination of patterns is changed, as is the case with conventional devices. It has a unique effect in that it does not need to have a large capacity.
