Embroidery machines are known.

In this type of automatic embroidery machine with boring, when the color of the embroidery thread is changed or a boring knife is selected, the color changing mechanism is operated, and the corresponding needle shaft is switched to another needle shaft to change the head. Engage with the drive section. In this state, the drive unit of the head unit is reciprocated while rotating the main shaft by the drive source, and the needle shaft selected by the drive unit is driven up and down, and the embroidery frame holding the embroidery cloth in the extended state. The boring knife or embroidery needle is moved with respect to the embroidery cloth by moving the frame with the frame moving mechanism in the X-axis and Y-axis directions. By sewing an embroidery thread of a desired color, an embroidery pattern including, for example, perforated embroidery is realized.

[0004] In this case, as shown in FIG. 10, one of a plurality of needle shafts 1 provided in a head portion of the embroidery machine main body is attached to any one of the needle shafts 1 via a mounting bracket 2. The boring knife 3 is provided with a predetermined offset L with respect to each of the embroidery needles 4 attached to the other needle shafts 1, and the offset L is generally set to about 12 mm. An embroidery cloth 5 held in a state of being extended on the embroidery frame is placed on a needle plate 6 of the embroidery machine main body, and the needle plate 6 has a boring hole 7 for a boring knife 3 and an embroidery needle 4.
Needle hole 8 is provided.

While the embroidery cloth 5 is moved by the frame moving mechanism in the X-axis and Y-axis directions together with the embroidery frame, the embroidery needle 4 is moved with respect to the embroidery cloth 5 to create an embroidery pattern. When the boring knife 3 cuts out a hole in the embroidery cloth 5, the color changing mechanism selects the needle shaft 1 on which the boring knife 3 is attached, and the embroidery frame and the embroidery frame are moved with a moving amount corresponding to the offset amount L. When the embroidery cloth 5 is moved in the X-axis or Y-axis direction (in general, there are many Y-axis directions,

The automatic embroidery sewing machine according to the present embodiment has the above-described configuration. The control device 22 controls the spindle motor 12, the frame moving actuator 13,
The color changing actuator 15 and the jump solenoid 16 are actuated to move the embroidery cloth 5 together with the embroidery frame while moving the boring knife 3 or the embroidery needle 4 selected on the head portion side. There is no particular difference in realizing embroidery patterns including perforated embroidery from the prior art.

However, the automatic embroidery sewing machine according to the present embodiment performs external data reading processing, sewing machine drive control processing, conversion arithmetic processing, and the like, as described later, based on the program shown in FIGS. It is intended to solve the above-mentioned problem of the prior art.

Next, embroidery data written on a floppy disk or the like as shown in FIG. 8 and read from the outside into the control device 22 via the floppy disk device 21 will be described.

That is, the embroidery data in FIG. 8 is F data which is a control signal on the movement of the hand, H data indicating the movement amount of the movement in the Y-axis direction, and V data indicating the movement amount of the movement of the needle in the X-axis direction. The H data and V data each have a bit of 0.1 mm.
1, 2, 4, 7-bit binary notation equivalent to the amount of movement of
8, 16, 32, and 64, and the corresponding portions are clarified by adding a circle as an identifier for explanation.

First, since the pattern starting point of the number (1) is the XY coordinate (0, 0), the sixth, seventh, and eighth rows of the V, H, and EB marks of the F data are provided. A circle as an identifier is attached to the eye, and unless the needle axis number (color of the embroidery thread) is changed, a circle is not added to the first to fifth columns of the F data, and the H data and the V data are not changed. It is assumed that H data = 0, V data = 0, and no circle is attached. And the hand movement data of the first stitch of the number (2) is the XY coordinate (-1.
X = −1.3 mm, Y = 0.5 mm
Therefore, in order to identify that the V data has a negative movement amount, the sixth column of the F data is not circled, and the seventh and eighth columns of the F data are circled. H data is 0.
Circles are added to the first and third rows indicating the amount of movement of 5 mm, and V
The data has circles in the first, third, and fourth columns indicating the amount of movement of 1.3 mm.

Next, for example, the hand movement data of the number (i) designating the needle axis number (7) of the boring knife 3 indicates the first stitch for boring, and the first to fourth columns and 6 to 8 of the F data. A circle is added to the column, H data = 12 mm, V data = 0, and the offset amount L of the boring knife 3 = 1.
A circle is provided so as to move the embroidery frame (embroidery thread 5) by 2 mm in the positive direction of the Y axis. And the number (i +
The hand movement data of 1) and (i + 2) indicate the second and third stitches by the boring knife 3, and H data = 6.
6mm, V data = -0.3mm and H data = -0.6
mm, V data = 0.3 mm, and a circle is provided so that the boring knife 3 moves the frame in the Y-axis and X-axis directions.

Further, for example, the hand movement data of the number (k) designating the needle axis number (1) indicates the last stitch for boring, and the first, fourth, sixth and eighth rows of the F data. Indicates that the color change should be performed by the color changing actuator 15 from the boring knife 3 to the embroidery needle 4 of the needle axis number (1), and H data = −12 mm, V
Data = 0, and a circle is provided so as to move the embroidery frame (embroidery thread 5) in the reverse direction by the offset amount L of the boring knife 3 by 12 mm in the negative direction of the Y axis. And
The needle movement data of the number (k + 1) indicates the first needle at which the embroidery is restarted by the embroidery needle 4 of the needle axis number (1), and H data = −1.
5 mm, V data = 3.2 mm, and a circle is provided so that the embroidery needle 4 of the needle axis number (1) moves the frame in the Y-axis and X-axis directions.

In FIG. 8, the hand movement data strings of numbers (i) to (k) indicate a data portion for boring. The first to fifth rows corresponding to the F1, F2, F3, F4, and F5 marks of the F data are appropriately combined to generate a jump signal, a sewing speed signal of the sewing machine, and a needle axis number for specifying the color of the embroidery thread. It is used as a signal and a rewind signal.

Next, an external data reading process performed when externally reading the embroidery data illustrated in FIG. 8 will be described with reference to FIGS.

First, when the reading process is started by operating the soft key 19, it is determined in step 1 whether or not the needle shaft number to which the boring knife 3 is attached is specified in the embroidery data to be read from the outside. When the determination is "YES", the needle axis number of the boring knife 3 is designated as the needle axis number (7), for example, as shown in the embroidery data shown in FIG. 19 and the like are operated by an operator, and conditions for giving a boring function are set.
When the boring knife 3 is attached to the needle shaft 1 with an offset L of 12 mm as shown in the example, the corresponding offset data is inputted by the ten keys 18 and stored in the storage area 22A in an updatable manner.

Next, in step 3, reading of embroidery data is started from the hand movement data of the number (1) illustrated in FIG.
Go to step 4 and read the number (1),
(2) Change the designation of the needle axis number in the hand movement data of
It is determined whether or not there is a color change function. If the determination is "YES", the F data for changing the designation of the needle axis number has been read. It is determined whether or not the needle axis number (7) is specified. If "NO" is determined in the step 5 or the step 4, since the F data in which the needle shaft number (7) of the boring knife 3 is designated is not read, the process proceeds to the step 6, and the reading of the embroidery data is continued. Then, in step 7, it is determined whether or not the F data of the hand movement data being read is an end function for designating the end of the embroidery data. If "NO" is determined, the processing from step 4 is repeated.

If "NO" is determined in step 1, the embroidery data does not use the boring knife 3, so that the process returns to step 8 and returns to perform the same reading processing as that of the prior art. I do.

On the other hand, if "YES" is determined in step 5, for example, the hand movement data of the number (i) shown in FIG.
Since the needle axis number (7) is designated, the process proceeds to step 9 in FIG. 3, and the boring function A is automatically assigned like the needle operation data of the number (i) shown in FIG. = 12 mm so that the offset amount L can be updated. In step 10, the hand movement data of the next numbers (i + 1), (i + 2),... Are sequentially read, and the reading of data is continued. In step 11, it is determined whether or not the F data serving as the color change function is read again. , "NO", the boring knife 3
, The reading of the data is continued at step 10.

When "YES" is determined in the step 11, the embroidery needle of the needle shaft number (1) is designated as the needle movement data of the number (k) shown in FIG. ) Indicates the last stitch for boring, so the process proceeds to step 12 where the boring function B is automatically added as in the case of the hand movement data of the number (k) shown in FIG.
The offset amount L in the reverse direction is set to be 12 mm so that it can be updated. Then, in step 13, the hand movement data after the number (k + 1) is continuously read again, and the processing after step 4 shown in FIG. 2 is repeated.

Thus, the embroidery data shown in FIG. 8 is rewritten as the embroidery data shown in FIG. 9 by the external data reading process shown in FIGS. 2 and 3, and the hand movement data of the number (i) is stored in the first column of the F data. The boring function A is automatically added by giving a circle to each of the eighth columns, and circles are respectively given to the fourth to seventh columns with H data = 12 mm . Also, numbers 1 to 4 F data (i + 1) hand motion data of specifying the needle axis number of boring knife 3 (7)
Each column is marked with a circle, and H data = 6.6 mm, V
A circle is attached as data = -0.3 mm. to this
First, drill holes in embroidery cloth 5 using boring knife 3
Is the XY coordinate (6.6,
−0.3). Their to, hand movement data items (k) the second column of the F data, bowling function B is automatically given by subjecting each circle 4-6 column and the eighth column, the H-data = -12 mm Each of the fourth to seventh columns is marked with a circle. in this way,
The data part for boring is number (i), (i + 1),
.. Is configured as a hand movement data string of three or more hands consisting of (k)
It is.

The identification data for specifying the boring functions A and B indicated by the numbers (i) and (k) in FIG. 9 are F data in a tape format called a so-called "U code", and are F1 data. Among the bit combinations of .about.F5 marks, the bit combinations which have not been allocated yet are used.

In the embroidery data shown in FIGS. 8 and 9, the case where the H data corresponding to the offset amount L of the boring knife 3 is equal is described. The H data serving as the offset data is appropriately updated by the condition setting in step 2 shown in FIG. 2, and even when the embroidery data includes a plurality of boring data portions, the processing in steps 9 and 12 is performed. , Offset data is collectively given to each data portion.

Next, a case where the sewing machine drive control processing is performed based on the embroidery data of FIG. 9 to which the boring functions A and B have been added as described above will be described with reference to FIGS.

First, when the processing operation is started by operating the soft key 19, the embroidery data shown in FIG. 9 is read in step 21, and the operation of the spindle motor 12, the frame moving actuator 13 and the like is controlled in step 22 based on this data. By moving the embroidery needle 5 on the head side while moving the embroidery cloth 5 together with the embroidery frame, embroidery on the embroidery cloth 5 is started.

Then, proceeding to step 23, it is determined whether function data including F data such as a jump signal, a sewing speed signal of the sewing machine, a needle axis number signal (color change function), and a rewind signal has been read during the embroidery. If the determination is "YES", it is determined whether the function data read in step 24 is the boring function A. If the determination is "NO" and the boring function A is not read, the step Step 25 and continue embroidery, step 2
At 6, it is determined whether or not the end function has been read.
When the determination is "NO", the processing after step 23 is repeated. If "YES" is determined in the step 26, the process proceeds to a step 27, in which an embroidery ending operation such as stitching, thread trimming, movement of an end point and the like is performed, and the process is ended.

On the other hand, if "YES" is determined in the step 24, for example, when the hand movement data of the number (i) shown in FIG. 9 is read, and the F data is the boring function A, Step 2 shown in FIG.
8, the frame is moved in the Y-axis direction by an offset amount L of H data = 12 mm, which is offset data, and in step 29, the color changing actuator 15 is operated based on the hand movement data of the number (i + 1), and the needle shaft number (7) The boring knife 3 is selected. In step 30, a boring operation is performed to cut out a hole in the embroidery cloth 5 with the boring knife 3 based on the hand movement data by the numbers (i + 1), (i + 2),..., And in step 31, it is determined whether the boring function B has been read. If the determination is "NO", the boring operation is continued at step 30.

If "YES" is determined in step 31, for example, the hand movement data of the number (k) shown in FIG. 9 is read, and the F data is the boring function B. In step 32, the frame is moved in the opposite direction by an offset amount L of H data = −12 mm as the offset data, and the needle axis number (1) is determined in step 25 shown in FIG. Embroidery is continued with the embroidery needle.

In the case where the embroidery data with the boring function illustrated in FIG. 9 is converted and calculated in order to correct the embroidery pattern such as enlargement, reduction, rotation or inversion,
The conversion operation shown in FIGS. 6 and 7 is executed.

That is, when a conversion operation such as enlargement, reduction, rotation, or inversion is selected by operating the soft key 19, the embroidery data shown in FIG. 9 is read in step 41, and the numbers (1) and (2) are read in step 42. ,..., The values of the H data and the V data are rewritten, and the conversion operation is started in order. In step 43, it is determined whether or not the function data is read, and “YES” is determined. At step 44, it is determined whether or not the read function data is the boring function A. If "NO" is determined and the boring function A is not read, the conversion operation is continued at step 45, In step 46, it is determined whether or not the end function has been read. If "NO" is determined, the processing in and after step 43 is performed. Repeated.

If "YES" is determined in the step 44, for example, when the hand movement data of the number (i) shown in FIG. 9 is read, and the F data is the boring function A, Step 4 shown in FIG.
In step 7, the conversion calculation of H data = 12 mm serving as offset data is prohibited, and the value of the offset amount L is fixed to the value set as the condition in step 2 in FIG.

In the next step 48, the number (i
The conversion operation is continued by rewriting the values of the H data and V data in the hand movement data after +1), and step 4 is performed.
In step 9, it is determined whether or not the boring function B has been read. If the determination is "YES", for example, the hand movement data of the number (k) shown in FIG. 9 is read, and the F data is the boring function. Since it is B, the process proceeds to step 50, where the offset data is fixed at H data = −12 mm, and the conversion operation is continued on the hand operation data after the number (k + 1) in step 45 shown in FIG.

Thus, according to the present embodiment, when the embroidery pattern is corrected by enlarging, reducing, rotating, or inverting the embroidery pattern, when the embroidery data is read from the outside, the boring data is read. Since the boring functions A and B automatically added to the data part can reliably identify the data part for boring and other data parts, the hand movement data provided with the boring functions A and B can be enlarged, reduced, The offset data corresponding to the offset amount L of the boring knife 3 can be fixed to the value at the time of setting the conditions without performing a conversion operation such as rotation or inversion, and the boring functions A and B are not provided. Conversion operation is performed only for the hand movement data of
Conversion operations such as enlargement, reduction, rotation, and inversion of the embroidery pattern can be accurately executed.

Since the boring functions A and B can be automatically added to the data portion for boring when the embroidery data is read from the outside, the boring functions A and B are complicated at the time of drive control of the automatic embroidery sewing machine or at the time of data conversion calculation. There is no need to perform a switch operation, and sewing machine drive control processing, conversion arithmetic processing, and the like can be performed in a short time, and workability can be greatly improved. The embroidery data to which the boring functions A and B are automatically added can be easily output to the outside via an external output means such as a floppy disk device 21, a tape puncher 23, or a communication line. Embroidery data provided with the boring functions A and B can be used as appropriate.

Therefore, in this embodiment, when reading the embroidery data from the outside, the boring functions A and B are automatically added to the boring data portion, so that the data conversion calculation and the like can be performed in a short time. Even if correction such as enlargement, reduction, rotation, or inversion of the embroidery pattern is performed, various effects such as high quality embroidery patterns including perforated embroidery can be achieved.

In the above embodiment, steps 9 and 12 of the programs shown in FIGS. 2 to 7 are specific examples of the boring function providing means which is a constituent element of the present invention. Step 12 shows a specific example of the offset data updating means,
Steps 41 to 50 in FIGS. 6 and 7 show specific examples of the conversion operation means.

In the above-described embodiment, the boring functions A and B have different data structures like the hand movement data of the numbers (i) and (k) shown in FIG. The present invention is not limited to this. For example, the boring functions A and B may have the same data configuration. In this case, when the first boring function is read, it can be identified as the first-hand stitching data for boring. When the boring function is read, it can be identified as the hand movement data of the last needle for boring.

Further, in the above embodiment, the boring function A is given by the hand movement data of the number (i) shown in FIG. 9, and the needle shaft number of the boring knife is designated by the hand movement data of the number (i + 1). However, instead of this, for example, the boring function A is given by the hand movement data of the number (i), and the needle axis number of the boring knife is designated. In the hand movement data of the number (i + 1), one row of F data is provided. Without adding a circle to the eyes, etc.
You may set so that a needle axis number may not be changed. Also, a boring function B is added to the hand movement data of the number (k), and a needle axis number other than the boring knife is designated. For the hand movement data of the number (k + 1), the first to fifth columns of the F data are used. It is also possible to set so that the needle axis number is not changed without adding a circle mark to the like.

On the other hand, in the above-described embodiment, an example is described in which embroidery data is written on a floppy disk, tape, or the like using a format method known as a so-called "U code". The invention is not limited to this. For example, embroidery written on a floppy disk or tape using another format method known as "F code" or "EL code", or a tape of 6 units, a wide jacquard card, or the like. 2, 3
The boring functions A and B can be automatically added by appropriately rewriting as embroidery data of "U code" by the external data reading process shown in FIG.

For example, in the case of the "EL code", the designation of the needle axis numbers is all stop signals, but the first stop signal is the same embroidery thread and the second stop signal is boring in advance. Since it is specified, if the setting is made for each stop signal at the time of reading data and converted to "U code", the boring function A,
B can be automatically added, and even if the embroidery data is “EL code”, the embroidery data is converted to the “U code” embroidery data once, and then the embroidery is executed immediately without any troublesome setting. be able to.
