The ROM 58 stores programs such as sewing control processing, which will be described later, and the CPU 56, when a predetermined command is input from the keyboard 24, the ROM 58.
Various processes are executed according to the program stored in. The FDD 63 is for reading embroidery data for forming a stitch pattern from a floppy disk which is an external storage device, and the read embroidery data is RA
Stored in M60.

The RAM 60, as shown in FIG.
An embroidery data storage area DA for storing embroidery data read from the FDD 63, a stitch data storage area SA for storing stitch data obtained by converting embroidery data by a known process, and a counter area used in a sewing control process described later. It has a CA and a work area WA.

Here, the stitch data stored in the stitch data storage area SA is the minimum unit control data for controlling one operation of the embroidery sewing machine 2, "stitch", "feed". "," Thread trimmer, "
"Color change", "End", etc. are arranged in the processing order.

Here, the "stitch" means that the sewing needle 34 is moved up and down and the moving mechanism 20 is driven to move to move the sewing needle 3
4 is control data for forming one stitch on the work cloth W by moving the work cloth 4 and the work cloth W held on the embroidery frame 18 relative to each other. The “feed” means the moving mechanism 20.

"Color change" is control data for moving the support case 10 by the color change motor 12 to change the sewing needle 34 vertically driven by the spindle motor 14 to one carrying embroidery threads of another color. is there. Also, "end" means
This is control data indicating the end of stitch data.

Next, the sewing control processing executed by the control device 22 will be described with reference to the flowcharts shown in FIGS. The CPU 56, when the power is turned on,
After performing an initialization process for initializing each unit of the control device 22 and each circuit connected to the input / output port 62, the sewing control process is performed.

As shown in FIG. 5, when the sewing control process is started, the CPU 56 first at S11, the keyboard 24.
It is determined whether or not the end key of is operated. If it is operated, the process is terminated as it is, and if it is not operated, a negative determination is made and the process proceeds to S13. In S13, the stitch data is read from the stitch data storage area SA described above. Then, the total number of "stitches" in the stitch data is set in the counter N (S15), and the counter Q,
After setting P to 0 and 1 respectively (S17, S1
9) and shifts to S21. In S21, a stitch data editing routine described later is executed to omit short stitches, and then S2 is executed.
Move to 3.

Here, the counters Q and P are both S21.
Of the stitch data editing routine, the counter Q indicates the number of stitches omitted, and the counter P indicates the number of stitches of the stitch being processed from the sewing start position. It is a thing. In S17 and S19, the stitch is not omitted before the stitch data editing routine is executed, so Q = 0 and 1 is set in the stitch data editing routine.
Since processing is performed from the second stitch, set P = 1 respectively.

At S23, the number Q of stitches omitted in the stitch data editing routine at S21 is subtracted from the total number N of stitches set at S15, and this is newly set as the total number N of stitches. At S25, the keyboard 2
It waits until the sewing start key of No. 4 is operated, and when it is operated, it proceeds to S27. In S27, the moving mechanism 20 performs the positioning of the embroidery frame 18 and the sewing with the sewing needle 34 based on the edited stitch data, and after the work cloth W is embroidered, the process proceeds to S11.

Next, FIG. 6 is a flow chart showing the stitch data editing routine of S21. When this routine is started, first, in S31, the P-th (as described above,
Of the XY components of the 1st) stitch at the start of this routine,
Let the longer value be L. In the following S33, L <0.3mm
If L is 0.3 mm or more, the process directly proceeds to S35. In S35, the counter P is incremented, and in the following S36, it is determined whether P> N, that is, whether or not the processing has been completed for all stitches. If P ≦ N (NO) and there is a stitch that has not been processed, the process proceeds to S31 again.

If L <0.3 mm is determined in S33, it is determined in subsequent S37 whether P = 1. If P = 1 (YES), in S39, the Pth or first stitch and the P + 1th or second stitch are integrated, and the process proceeds to S40. Here, integration means
For example, a new stitch from the start point of the Pth stitch to the end point of the P + 1st stitch is set, and this is set to the Pth and P +
It can be executed by substituting the first stitch. Further, in S40, the counter Q is incremented and the process proceeds to S35.

When it is determined in S37 that P ≠ 1 (NO), the process proceeds to S41 and the vectors of the (P-1) th and (P + 1) th stitches are calculated. In subsequent S43, it is determined which of the vectors of the P-1st and P + 1th stitches is closer to the direction of the Pth stitch. If the P + 1st stitch is closer to the Pth stitch, the P + 1st stitch and the Pth stitch are integrated in S39, and S4
Move to 0. On the other hand, if the P-1st stitch is closer to the Pth stitch, the P-1st stitch and the Pth stitch are integrated in S45, and the process from S40 is performed. Move to. The above processing is executed for each stitch, and when all the stitches have been processed, P = N + 1. Then, an affirmative decision is made in S36, and the process returns to the main routine.

Next, the operation of the present embodiment configured as described above will be described. FIG. 7 is an explanatory diagram showing an example of execution of stitch data, and shows that the same embroidery thread is used to embroider between the dropped needle positions a to i. Here, in the stitch data before editing, a drop position p is set between the drop positions c and d, and a drop position q is set between the drop positions e and f.
(The stitch formed between the needle drop position c and the needle drop position p: the other stitches are also written in the same manner) and the stitch qf are
Both the X component and the Y component are less than 0.3 mm. Then, in the stitch data editing routine described above, the stitch c
When the process of p is reached, YES in S33 and NO in S37.
Then, the process proceeds to S41 and thereafter. Then, of the stitches bc and pd, the stitches in the direction close to the stitch cp are determined (S41, S43), and the stitches pd and stitch cp in the close direction are integrated (S39). Then, in the edited stitch data, the needle drop position p is omitted and the stitch cd is set. Similarly, the stitch qf is integrated with the stitch eq (S45), and the stitch position ef is set by omitting the needle drop position q in the edited stitch data.

Therefore, in this embodiment, stitch data (corresponding to embroidery data in a one-to-one correspondence) can be edited by omitting the stitches in which both the X component and the Y component are less than 0.3 mm. Therefore, it is possible to prevent the embroidery thread from breaking. In addition, such data editing can be performed, for example, by replacing the control data “stitch” related to the stitch cp and the control data “stitch” related to the stitch pd with one control data “stitch”, or the stitch cp. It can be easily executed by replacing the control data “stitch” related to the above with the control data “feed”. That is, only the control data relating to the stitches cp, pd, eq, qf that are integrated with each other need only be changed, and the data relating to other stitches need not be changed. Therefore, the data editing process can be simplified and the speed thereof can be improved.

Further, in this embodiment, the directions of the respective stitches are compared, and the short stitches cp and qf are compared with the stitches pd and
integrated with eq. Therefore, the change in the shape of the embroidery due to data editing can be sufficiently suppressed. For example,
When a short stitch is always integrated with the next stitch, the stitch qf and the stitch fg are integrated to set the stitch qg as shown by the broken line in FIG. 7. Then, the shape of the embroidery is deformed to some extent, but in the present embodiment, such a situation can be prevented. Further, the process of comparing the magnitude of the shape change depending on the direction of the stitch can be executed very easily by calculating the inner product of the vector. Therefore, in the present embodiment, it is possible to extremely improve the editing processing speed while suppressing the embroidery shape change due to the data editing.

In the above embodiment, the control device 22
Corresponds to the embroidery data editing device of the present invention. Further, in the processing, S31 and S33 are the short stitch detecting means, and S37 is
~ 45 are processes corresponding to the data editing means,
Particularly, S39 and S45 are integrated means, and S41 and S43 are
Are processes corresponding to the selection means.

Furthermore, the present invention is not limited to the above embodiments, but can be carried out in various modes without departing from the spirit of the present invention. For example, in the above embodiment,
Replace the short stitches cp and qf with the stitches pd and eq that are close in direction.
, But a short seam may always be integrated with the next seam or always with the previous seam. in this case,
Although the shape of the embroidery may change as described above, the processing can be further simplified and the processing speed can be further improved.

In recent years, an embroidery sewing machine having a power transmission interruption means for temporarily interrupting the transmission of power from the drive system to the needle bar has been considered, but the embroidery sewing machine 2 is provided with this kind of structure. The short stitches cp and qf as follows:
Can be omitted. FIG. 8 is a perspective view showing the structure of the power transmission path of the embroidery sewing machine 2. The drive lever 71 swings in the vertical direction (arrow a) by the rotation of the spindle motor 14. The tip 71a of the drive lever 71 engages with the protrusion 28a protruding from the side surface of the needle bar 28, and transmits the motion of the drive lever 71 to the needle bar 28. Then, the sewing needle 34 slides up and down together with the needle bar 28 to form a stitch on the work cloth W. Here, the sliding shaft 73a of the solenoid 73 is fixed to the side surface of the drive lever 71, and the energization of the solenoid 73 causes the drive lever 71 to swing in the direction perpendicular to the swing surface (direction of arrow b). Then, the tip 71a is disengaged from the protrusion 28a, and the movement of the drive lever 71 is not transmitted to the needle bar 28. That is, the solenoid 73 corresponds to power transmission interruption means.

Therefore, if the solenoid 73 is driven at a timing corresponding to the needle drop positions p and q in FIG. 7, the sewing needle 34 will not descend at the needle drop positions p and q. Therefore, the short stitches cp and qf can be omitted as in the above-mentioned embodiment only by providing the drive signal to the solenoid 73 without changing the stitch data as described above.

Therefore, the editing process can be further simplified and the processing speed can be further improved. Also, a short seam c
When p and qf are omitted, if the control data “feed” is used, it is necessary to stop the spindle motor 14 each time,
The sewing speed may decrease. However, in this embodiment, the operation of the spindle motor 14 and the like may be exactly the same as when the stitch data is not edited, so that it is possible to favorably prevent the sewing speed from decreasing. Therefore, in this embodiment, both the processing speed and the sewing speed can be improved.

In each of the above embodiments, the embroidery sewing machine 2 incorporates the control device 22 as an embroidery data editing device, but the present invention may be provided separately from the embroidery sewing machine 2.
For example, the stitch data editing routine illustrated in FIG. 6 and the process of adding the drive signal of the solenoid 73 to the stitch data may be executed by a personal computer provided separately. In this case, the personal computer corresponds to the embroidery data editing device.

[0042]

As described above in detail, according to the first aspect of the invention, embroidery data can be edited by omitting short stitches having a length less than a predetermined value. Therefore, it is possible to prevent the short stitches from existing in the edited embroidery data and prevent the embroidery thread from breaking.

According to the second aspect of the present invention, the stitching process is simplified by integrating the adjacent stitches, and the stitching time is shortened because the number of data is reduced by the integration. It is possible to reduce the change in the shape of the embroidery by selecting the one with the smallest change in the shape of the embroidery as an integration target. Therefore, claim 1
In addition to the effects of the invention described above, it is possible to obtain the effect that the edit processing speed and the sewing speed can be improved while suppressing the shape change of the embroidery due to data editing.

According to the third aspect of the invention, the stitch to be integrated can be selected by a very simple process. Therefore, in addition to the effect of the invention described in claim 2, the editing process can be further simplified and the processing speed can be further improved. Furthermore, in the invention described in claim 4, in addition to the effects of the inventions of claims 1 to 3, the following effects can be obtained. That is, by adding drive data of the power transmission interruption means to the embroidery data and omitting stitches,
It is possible to prevent the sewing speed from lowering and further simplify the editing process. Therefore, both the processing speed and the sewing speed can be improved.
