The above-mentioned generation circuit 24 and the like for generating the signal are provided.

Further, the electronic control unit 70 has the A / D
Transmitting circuit 20 for transmitting the quantized detection data output from the converter 80 to a data processing device 300 described later.
0 and a receiving circuit 210 that receives command data from the data processing device 300. A data communication cable 400 connects the electronic control circuit 70 and the data processing device 300 in the main pattern sewing machine.

The ROM 75 has a program area,
A program for converting the command data from the data processing device 300 into the drive amount of the step motor 15 is written therein.

Next, the data processing device 300 will be described.

The data processing device 300 has a CPU 373.
A receiving circuit 310 that receives detection data that enters through the ROM 375, the RAM 378, and the data communication cable 400, and a transmission that sends out the calculation result of the pattern deviation amount obtained by processing the received detection data through the data communication cable 400. The circuit 320, an external storage device 330 for storing various programs, and an information input circuit 340 for receiving information about a work cloth from a camera, a scanner or the like before starting sewing.

The ROM 375 and the external storage device 33 are also provided.
0 has a program area, only the basic control program is stored in advance in the program area of the ROM 375, and the program area of the external storage device 330 is
A program for a pattern matching control routine described later is stored in advance.

There are various miscellaneous patterns in the color configuration of the patterns of the work cloth which are the objects of pattern matching sewing. In the pattern matching control routine program, the pattern matching sewing machine analyzes the patterns of as many types as possible and calculates the pattern deviation amount, and in order to calculate the pattern deviation amount, three pattern detection modes for calculating the pattern deviation amount by algorithms of different methods. Is equipped with. The three pattern detection modes are a brightness signal generation subroutine (mode 1), a hue difference signal generation routine (mode 2), and a hue difference emphasis signal generation routine (mode 3).
And are respectively stored in advance in the program area of the external storage device 330.

Mode 1 generates processed data suitable for recognizing an achromatic pattern, mode 2 a normal color pattern, and mode 3 a particularly fine color pattern. For example, in the case of a pattern for which data as shown in FIG. 13 is obtained, a characteristic pattern does not appear depending on the brightness data (A) generated in mode 1 and the difference data (B) generated in mode 2. According to the difference emphasis data (C) generated in the mode 3, a pattern corresponding to a fine pattern appears. In this way, by selecting the optimum pattern detection mode according to the color of the pattern, it is possible to accurately extract patterns corresponding to various types of patterns. Incidentally, this mode is set in advance before the suturing work.

The RAM 378 has a work area, and the pattern matching control routine program is expanded and executed in the work area of the RAM 378 when the power is turned on. Further, the RAM 378 has a rewritable memory area in which the data received by the receiving circuit 310 and the data generated in the processing process are sequentially stored. Further, the RAM 378 is constantly backed up by a backup power source (not shown), and stores necessary data and the like.

The pattern matching operation of the work cloth by the pattern matching device will be described below with reference to the flow charts of FIGS. 9 to 12.

First, the interrupt processing routine shown in FIG. 9 will be described.

The interrupt processing routine is activated by the fall of the synchronizing signal of the rotation synchronizing sensor 20. Since this rotation synchronization sensor 20 generates 24 synchronization signals each time the main shaft of the sewing machine makes one rotation, the interrupt process is repeatedly executed every time the main shaft rotates 15 degrees.

In the interrupt processing routine, as shown in FIG. 9, first, it is determined whether or not the synchronizing signal from the rotation synchronizing sensor 20 is within the feeding operation period of the upper and lower work cloths 10 and 12, that is, the sewing needle 1 is raised. Then, it is checked whether the upper feed dog 6 and the lower feed tooth 4 are interrupting the feed operation period during which the upper and lower work cloths 10 and 12 are being transported (S10). This operation period is determined by the detection data of the needle position detection sensors 16 and 18. If it is not within the feed operation period (S
10: NO), this routine is terminated without executing anything, and returns to the processing of the pattern matching control routine described later.

On the other hand, when the synchronizing signal from the rotation synchronizing sensor 20 is within the feed operation period (S10: YES), the analog signals from the photodiodes 60 and 62 are converted into digital signals by the A / D converter 80, and the six signals are converted. A set of color signals (red, blue, and green color signals of the upper work cloth 10 and red, blue, and green color signals of the lower work cloth 12) is set as one set, and one set of color signal data is used as quantized data for the transmission circuit 200. To the data processing device 300 via the communication cable 400, the value of the number C of color signal data is incremented by 1, and then the process returns to the execution of the pattern matching control routine (S20, S30).

As a result, while the upper and lower work cloths 10 and 12 are being moved by the upper feed dog 6 and the lower feed dog 4 in the direction of arrow A in FIGS. 2 and 3, only the detected color signal data is transferred from the sewing machine side. It is transmitted to the data processing device 300. During the sewing work, the above-described interrupt processing routine is executed in synchronization with the rotation of the sewing machine motor 2, and the data is continuously sent from the transmission circuit 210 to the data processing device 300.

Next, the pattern matching control routine shown in FIGS. 10 to 12 will be described.

When the pattern matching control routine is started, the CPU 73 of the electronic control unit 70 transmits the set pattern interval data from the transmission circuit 200 to the data processing unit 300 via the communication cable 400 (S100). The pattern interval data is an interval at which patterns can be recognized as a pattern on the work cloth 10. The pattern matching sewing machine calculates the pattern deviation amount with this interval as a unit. still,
The pattern interval is set in advance by the operator before inputting the pattern matching sewing by means such as input or automatic setting by trial sewing.

Next, the CPU 73 of the electronic control unit 70 stands by until the upper and lower work cloths 10 and 12 are set and the foot pedal 22 is depressed (S110). When the foot pedal 22 is depressed (S110: YES), it is next determined whether or not the amount of pattern deviation is received from the data processing device 300 in order to correct the pattern deviation between the upper and lower sides, and the pattern is determined. When the deviation amount is received (S120: YE
S), the pattern deviation amount is stored in the RAM 78 (S13).
0). Then, the drive amount of the stepping motor 15 is adjusted, and the upper feed amount is changed so as to eliminate the pattern deviation amount (S140). If the pattern shift amount is not received (S120: NO), the sewing work is performed with a preset appropriate upper feed amount or a continuous upper feed amount (S15).
0).

Incidentally, this appropriate feed amount is set before the start of sewing by setting by the operator or automatic setting by trial sewing as in the case of the above-mentioned pattern interval data. Regarding this proper delivery, Japanese Patent Application No. 3-1796 filed by the present applicant
Please refer to it for the details because it is pending in No. 3.

On the other hand, the CPU 37 of the data processing device 300
In 3 (see FIG. 11), when the pattern interval data is received (S210: YES), the condition for starting the calculation of the pattern deviation amount is set. First, the specified length L, which is the feed amount of the work cloth 10, is set based on the pattern interval data received from the CPU 73 of the electronic control unit 70 (S220), and then the work cloth 10/12 is specified length L. A threshold value for determining whether or not the data has been sent is obtained from the number of color signal data (S230). Hereinafter, the threshold value is the specified number Cm.
And

For example, when the specified length L is set to 30 [mm] and the feed amount is set to 1 [mm], the number of synchronization signals within the operating range per revolution of the main spindle is 10 [pulses]. 10 [pulse] x 30 [mm] / 1 [mm]
By calculating, the specified number Cm is calculated as 300.

Then, the number of calculations K and the value of the color signal data C assigned to the RAM 378 are cleared to "0" (S240, S250).

Next, it is determined whether or not the number of times the pattern shift amount is calculated is the first time (S260), and the number C of color signal data.
Determines whether the number has reached the specified number Cm (S27
0), the CPU 373 on the data processing device side waits until the pattern shift amount can be calculated. Then, when it is determined that the value of the number of calculations K is not "0" (S260: NO), that is, when the calculation of the pattern deviation amount is already performed, or
When the number C of color signal data reaches the specified number Cm (S2
70: YES), and shifts to the pattern shift amount calculation processing (FIG. 1).
2). When the pattern shift amount is calculated for the first time, the CPU 373 on the data processing device 300 side waits until the color signal data number C reaches the specified number Cm.

Regarding the process of calculating the pattern deviation amount, refer to Japanese Patent Application Laid-Open No. 1-192389 filed by the applicant of the present invention.

Next, the CPU 37 of the data processing device 300
In 3, the preset mode algorithm is selected and the pattern shift amount is obtained (S300 to S34).
0), the pattern shift amount is determined by the transmission circuit 320 of the data processing device 300 and the reception circuit 21 of the electronic control device 70.
0 via the communication cable 400 (S35
0). Then, the value of the number of calculations K is incremented by 1 (S360). On the side of the data processing device 300, data such as the number of calculations K and the number C of data are sequentially updated in the memory area of the RAM 378.

The CPU 73 of the electronic control unit 70 adjusts the upper feed amount according to the amount of pattern shift received as described above and the degree of engagement of the upper and lower work cloths 10 and 12 set in advance, and the upper and lower feed amounts are adjusted. The relative speed difference between the work cloths 10 and 12 is controlled, and the upper and lower work cloths 10 and 12 are sewn with the handles of both cloths matched.

During the sewing work, processing for the sewing work (S1
00-S150) is performed by the CPU 73 of the electronic control unit 70, and processing for pattern recognition (S210-S270, S3) is performed.
00-S360) to the CPU 37 of the data processing device 300.
3, the load on each of the CPU 373 of the data processing device 300 and the CPU 73 of the electronic control device 70 is reduced, and the processing speed of the CPU 373 of the control device 300 and the CPU 73 of the electronic control device 70 is increased.

Further, since the CPU 373 of the data processing device 300, which is different from the CPU 73 of the electronic control device 70, performs the arithmetic processing for eliminating the pattern deviation amount, the CPU 73 of the electronic control device 70 focuses on sewing. It is possible to design with the improvement of the performance of the sewing machine, while the same applies to the design of the CPU 373 of the data processing device 300. When improving the performance of the data processing device 300 or changing the algorithm for analyzing the pattern, it does not physically or electrically affect the electronic control device 70. Therefore, the device on the data processing device 300 side is not affected. It is possible to improve and change only in consideration of the above, and the improvement and change of the device are minimized on the data processing device 300 side, and the improvement and change can be easily performed. Further, considering the transmission / reception of data to / from the sewing machine, various high-speed computing devices can be connected to the sewing machine, the working efficiency is improved, and sewing which requires a complicated algorithm becomes possible.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and it goes without saying that the present invention can be implemented in various modes without departing from the spirit of the present invention. .

For example, in the present embodiment, one sewing machine was actually used for stitching, but if the data processing apparatus performs processing in a time-division manner even if the number of sewing machines is increased to a plurality, the capital investment will be increased. The cost required for the sewing machine is enough for the sewing machine.

Also, when calculating the pattern deviation amount, it may be necessary to develop a dedicated algorithm depending on the fabric, and the ROM storing the program in the external storage device 330 of the data processing device 300. Since it is only necessary to change the ROM, it is not necessary to replace the ROM of each sewing machine, so the labor of replacing the ROM is reduced.

In this embodiment, the device for recognizing a one-dimensional pattern has been described, but the present invention can be applied to a device for recognizing a two-dimensional pattern.

If a sensor capable of detecting a two-dimensional pattern and pattern is provided, not only horizontal pattern alignment as in the present embodiment, but also vertical pattern alignment and material edge alignment can be realized. Particularly in the case of two-dimensional data processing, the load of data processing is large. Therefore, providing each sewing machine with the data processing device 300 leads to a significant increase in cost. Therefore, if the configuration as in this embodiment is adopted, the increase in cost does not change much even if the number of sewing machines increases.

Further, even if the data processing technology advances, only the data processing device 300 needs to be exchanged, so that the sewing machine does not need to be changed. Therefore, it leads to effective use of resources. Depending on the number of sewing machines, the data processing device 30
It is possible to increase the processing speed by increasing the number of 0's.

Before the sewing of the work cloth is started, the cloth data of the work cloth is taken in the data processing device 300 through the information input circuit 340 in advance by a camera, a scanner, etc., whereby the pattern interval is set and the pattern color type is set. Since the shape of the work cloth can be automatically set before the start of sewing, the burden on the operator who actually stitches on the sewing machine side is reduced, and the mistake of setting by the operator is also reduced, so that the precision of stitching is also improved. 2).

In this embodiment, two work cloths 10
Twelve stitches were performed, but the pattern and shape of discontinuous portions in one cloth may be matched, or the pattern and shape of three or more cloths may be matched.

Information about the work cloth obtained at the work cloth generation step, the pattern design step, and the cutting step can also be fetched through the information input circuit 340 of the data processing device 300, whereby the work cloth is obtained. The burden on the operator involved in suturing is further reduced, which leads to an improvement in the automation rate. The information is exchanged in the form of a floppy disk or the like by the data processing device 3.
00 through the external storage device 330.

[0065]

As described above in detail, according to the dough handle and shape-matching suturing device of the present invention as defined in claim 1, the handle is a data processing means different from the suturing control means for processing for suturing work. Since the processing for shape matching is shared, the processing speed of the stitching control means and the data processing means is increased, and the work efficiency is improved. Also, if there are multiple sewing machines, the sewing machine can be improved / changed by modifying / changing the data processing means instead of modifying / changing each sewing machine. The cost can be reduced.

Furthermore, according to the good cloth handle and shape matching suturing device of the second aspect, the type of processing of the data processing means is automatically determined based on the detection result of the second detecting means. It is easy to use because it saves time and effort in sewing work, and is suitable as an automated device.
