Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a lace embroidery machine having a function of embroidering by combining a plurality of pattern data.

Summary of the Invention: By setting and storing in advance a plurality of pattern data, each of which is a unit of stitching, each with a pattern data identifier attached thereto, and inputting and setting a series of ordered pattern data identifiers, a series of patterns 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.

[Prior art] A lace embroidery machine that operates based on a pattern data signal read from a tape, card, etc. is capable of repeatedly embroidering the same pattern, reversing the pattern vertically or horizontally, or stitching different patterns. When stitching together, there is a method of rewinding the tape or changing the hanger each time one pattern is finished, but with this method, you can confirm the completion of the eight patterns, rewinding the tape, or changing the hanger. Preparation work such as confirmation before starting took a long time and work efficiency was extremely low.

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. However, the disadvantage was that the memory capacity of the embroidery machine needed to be increased.

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 described above.

K 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 appropriately combining a plurality of embroidery handles for embroidery. It is to provide.

Means for Solving Problem K] 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 having a pattern data identifier attached thereto; a second storage means for storing a series of pattern data identifiers;
processing means for continuously reading pattern data corresponding to the pattern data identifier stored in the storage means from the first storage means; The pattern data identifier stored in the second storage means is continuously read out by the processing means and is automatically embroidered.

Further, a polarity reversal symbol, a number of repetitions, etc. are attached to each of a series of pattern data identifiers, and a start symbol, an end symbol, and a number of repetitions are inserted before and after a plurality of pattern data identifiers.

[1] By doing this, when stitching, the pattern data stored in the first storage means is appropriately combined according to the series of pattern data identifiers stored in the second storage means, and the stitching is automatically performed. .

K Embodiment An embodiment of the present invention will be described with reference to the drawings.

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

The central processing unit stores the pattern data input from the tape input unit and the series of pattern data identifiers input from the key input unit in first and second storage units including a RAM, a floppy disk, a hard disk, etc.; Furthermore, when driving the embroidery machine, these signals are sequentially read out from the first and second storage sections to create a embroidery machine drive signal.

The tape input section inputs pattern data, which is a stitching unit, from an external storage means such as a tape, card, or floppy disk, or from a stitching CAI) device to the central processing section.

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

As shown in FIG. 2, the first storage unit stores a plurality of pattern data each having a pattern data identifier,
Further, as shown in FIG. 3, the second storage section stores a series of pattern data identifiers and auxiliary symbols that determine the arrangement of each pattern data when stitching.

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 functions such as needle, polar, polar regulation, final tightening and shuttle operation locking, main shaft rotation control, 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, registering the pattern data identifier, and storing it in the first storage unit.

■Reading a series of pattern data identifiers and auxiliary symbols,
Storage 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, and to confirm that there is no duplication. ) is stored in the first storage unit.

As shown in Figure 3, the operation (■) is to operate the keypad while looking at the display to arrange the pattern data identifiers corresponding to each pattern data to be stitched in the order to be stitched. After setting a polarity reversal symbol, the number of repetitions (of two types), a start symbol, an end symbol, etc. for each, they are stored in the second storage section.

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 ■ and ■, respectively, and the symbol M2 in the left column of the figure indicates the frame of each stitch in the pattern data. This is a polarity reversal symbol that reverses the polarity of the moving direction left and right.

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 repeat a series of pattern data identifiers including S and E a specified number of times by further sandwiching 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.

Operation (2) is executed according to the sequence shown in FIG. For example, to explain the pattern shown in FIG. 3 as an example, a series of pattern data identifiers are read 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 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 is output, and the start symbol is output. A combination of the embroidery pattern C (with its polarity reversed) sandwiched between S and the end symbol E and the embroidery pattern is output three times, and finally the embroidery pattern B is output.

Therefore, if the stitching is carried out according to the pattern shown in FIG. 3, the patterns will be stitched in the order shown in FIG.

It is also possible to store a plurality of sets of pattern data identifiers and auxiliary symbols in the second storage section (each with a different program number), and use any of them as needed.

Furthermore, the lace embroidery machine to which the present invention is applied is not limited to a servo drive machine, but also includes a mechanical jacquard machine equipped with a device for electrically controlling the selection board.
5) can also be used.

Effects of the Invention As explained above, the lace embroidery machine of this invention has the following effects:
Stitching can be performed by arbitrarily combining the pattern data that is a stitching unit stored in the first storage means with a series of pattern data identifiers stored in the second storage means. As shown in the figure, there is no need to spend a lot of time creating tape every time the combination of patterns is changed, and there is no need to increase the memory capacity of the embroidery machine.
