Example 5. Next, an embodiment of the fifth invention will be described. A method of setting the setting range of the rotation speed of each state of the sewing machine 5 will be described. The setting of each rotation speed of the sewing machine 5 is performed by the setting means, for example, the push button switch 21 and the display means 22 built in the sewing machine control device 25 of FIG. For example, when f and g of the push button switch 21 are simultaneously pressed for several seconds, the microcomputer 20 determines that the sewing machine 5 is in the rotation speed setting mode. In this mode, the microcomputer 20 causes the display means 22 to display each setting item of the sewing machine 5 according to the push button switch 21 operated by the user. In this state, the user operates f, g of the push button switch 21 to select the item of the number of revolutions of the sewing machine 5 to be set while looking at the display means 22, and selects a, b, c, of the push button switch 21. Operate d to get the desired value. For example, set the rotation speed of the sewing machine 5 at high speed to 40
When setting to 00s / min, the push button switch 21 is operated as described above to enter the sewing machine rotation speed setting mode. Then, the upper one of the 5-digit display means 22
As shown in FIG. 15, the switches a, b, c, d are operated to display “H.” as shown in FIG. "4000"
Is displayed. The microcomputer 20 controls the rotation speed of the sewing machine according to the rotation speed of the sewing machine 5 set in this way. Further, in order to set the setting range (rotation speed limiter) for the setting of the rotation speed of each state of the sewing machine 5 described above, the push button shown in FIG. This is performed by the switch 21 and the display means 22. For example, if f, g, and d of the push button switch 21 are simultaneously pressed for several seconds, the microcomputer 20 determines that the sewing machine 5 is in the rotation speed limiter setting mode. In this mode, the microcomputer 20 causes the display means 22 to display each setting item of the sewing machine 5 according to the push button switch 21 operated by the user. In this state, the user presses f of the push button switch 21,
By operating g, the item of the rotational speed limiter of the state of the sewing machine 5 desired to be set is selected while observing the display means 22, and the push button switches 21 c and d are operated to set the desired numerical value. For example, the maximum value (upper limit) of the rotation speed setting range of the sewing machine 5 is 2000 s / min, and the minimum value (lower limit) is 1
When setting to 00 s / min, first, as described above, the push button switch 21 is operated to enter the rotation speed limiter setting mode of the sewing machine 5. Then, "LHH." Is displayed on the upper 3 digits of the 5-digit display means 22 by using the switches f and g as shown in FIG. 16, and the setting item of the maximum value of the rotation speed limiter at high speed is selected. In this state, the switches c and d are operated to display "20" (the display unit is 100 s / min) on the lower two digits of the display means 22 and set the upper limit to 2000 s / min. Similarly for the minimum value (lower limit) of the setting range of the rotational speed, the switches f and g are used to display “LHL.” As shown in FIG. 18, the minimum setting item is selected, and the switches c and d are selected. Operate "01" as shown in Fig. 19 (display unit is 100s / m
in) and set the lower limit to 100 s / min. FIG. 20 is a block diagram showing the setting range of the rotation speed setting when the rotation speed limiter at high speed is set as described above. By setting the rotation speed limiter upper limit to 2000 s / min and the lower limit to 100 s / min, , That the rotation speed of the sewing machine 5 at high speed can be set in the range of 100 to 2000 s / min. Further, although the case of the number of revolutions at the time of high speed is described above, the upper limit and the lower limit of the setting range can be freely set for the setting of the number of revolutions of each state of the sewing machine 5 such as low speed and thread cutting. Can be set.

FIG. 21 is a flow chart when the upper and lower limits of the rotation speed setting range are set in the rotation speed limiter setting mode. As shown in FIG. 21, comparison of the upper limit value (MAX) and the lower limit value (MIN) of the rotation speed setting range set in the rotation speed limiter setting mode with the current setting value set in the rotation speed setting mode. Each time, the set value this time is the upper limit value (MAX) and the lower limit value (MI
If it is between N), the current set value is valid as it is, and if it is larger than the upper limit value (MAX) and smaller than the lower limit value (MIN), the lower limit value (MIN) is substituted for the current set value. By performing the rotation speed limiter processing in this manner, it is impossible to set the rotation speed above the upper limit and below the lower limit of the rotation speed setting range set by the rotation speed limiter setting mode. In addition, in FIG. 21, when the set value of this time is larger than the upper limit value (MAX), the configuration is such that the lower limit value (MIN) is returned to. However, as shown in FIG. Larger than MAX),
The upper limit value (MAX) may be substituted for the current set value so that setting above the upper limit value cannot be performed.

Example 6. Next, an embodiment of the sixth invention will be described. The data is set by the setting means, such as the push button switch 21 and the display means 22, built in the sewing machine controller 25 of FIG. For example, when f, g, and a of the push button switch 21 are simultaneously pressed for several seconds, the microcomputer 20 determines that the sewing machine controller is in the input / output check mode (fault diagnosis mode). In this mode, the microcomputer 20 causes the S1 signal corresponding to the depression operation of the pedal device 26, the S2 signal corresponding to the deep kick back operation of the pedal device 26, the S3 signal corresponding to the shallow kick back operation of the pedal device 26, and the needle position.

In this state, when the needle position of the sewing machine reaches the upper position, if the needle upper position signal UP detected by the needle position detecting mechanism 7 is normally input to the sewing machine control device, the 5-digit display means 22 is displayed. 25 is displayed as "ON" in the lower two digits, and "OF" is displayed as shown in FIG. 26 if no input signal is input. Further, the S1 signal corresponding to the stepping operation of the pedal device 12, the S2 signal corresponding to the deep kicking back operation of the pedal device 26, the S3 signal corresponding to the shallow kicking back of the pedal device 26, and the speed detector of the sewing machine drive motor 8 With respect to the input signals such as the speed detection signal 10 as well, the input state can be confirmed by displaying on the display means 22 whether or not each input signal is input to the sewing machine control device.

Example 7. Next, an embodiment of the seventh invention will be described. The data is set by the setting means such as the push button switch 21 and the display means 23 built in the sewing machine controller 25 of FIG. For example, when f, g, and a of the push button switch 21 are simultaneously pressed for several seconds, the microcomputer 20 determines that the sewing machine controller is in the input / output check mode (fault diagnosis mode). In this mode, the microcomputer 20 is connected to the sewing machine control device, and the solenoid drive device 1 for performing operations such as thread trimming, thread loosening, thread wiping and reverse stitching.
4 and the output signal output to each output device such as the presser foot lifting device 13 for automatically lifting the presser foot of the sewing machine 5 is determined from each output port of the microcomputer 20, and the output The state is displayed on the display means 22. For example, suppose that it is desired to confirm whether the output signal is normally output to the presser foot lifting device 13 in order to diagnose whether the presser foot lifting device 13 is operating normally or is normally connected. FIG. 27 shows a flowchart in that case. As shown in the flowchart of FIG. 27, first, the push button switch 21 is operated to enter the input / output check mode of the sewing machine controller. Then, using the switches f and g, "FU." Is displayed on the upper 3 digits of the 5-digit display means 22 as shown in FIG. 28, and the item of output to be checked is selected. In this state, if an output signal is normally output from the sewing machine control device to the presser foot lifting device 13, "ON" is displayed in the lower two digits of the 5-digit display means 22 as shown in FIG. If is not output, “OF” is displayed as shown in FIG. In addition, regarding output signals of the solenoid drive device 14 for performing operations such as thread trimming, thread loosening, thread wiping, and reverse stitching, the output state is the same as above, and each output signal is output from the sewing machine controller.

As described above, according to the sewing machine control device of the first invention, when the model of the sewing machine main body is changed, or when the sewing machine control device is replaced with a sewing machine of a different model, the sewing machine model is changed. It is possible to easily and collectively set output and input functions suitable for a large number of switches for exclusive use without the need for complicated settings.

Further, according to the sewing machine control device of the second invention, when the sewing machine model is set, the setting data corresponding to the selected model is cleared after the already set setting data is cleared. Since the configuration is such that the reading and the operation of the sewing machine are controlled, it is possible to prevent the problem that the setting other than the model data of the set sewing machine remains and the sewing machine malfunctions.

Further, according to the sewing machine control device of the third invention, when the sewing machine main body and the sewing machine control device are connected, the setting data corresponding to the model of the connected sewing machine is automatically set. Since the storage means for storing the set data is provided on the sewing machine main body side, it is not necessary to perform the setting operation of the sewing machine model, and the sewing machine model can be connected just by connecting the sewing machine main body and the sewing machine control device. Corresponding setting data can be set automatically.

Further, according to the sewing machine control device of the fourth invention, when the model of the sewing machine main body is changed, or when the sewing machine control device is replaced with a sewing machine of a different model, the sewing machine control device is different from the conventional one. Is not limited by the switch provided as the model selecting means, and there is no need to provide a hexadecimal select switch or a switch corresponding to each model as the model selecting means of the sewing machine. , And various setting values can be easily set collectively.

Further, according to the sewing machine control device of the fifth invention, the setting range for the setting of the rotation speed of each state of the sewing machine is not decided in advance unlike the conventional control device, and the setting range is set in advance. The upper and lower limits of the setting range can be set freely, and the configuration is such that the number of rotations above the upper limit and below the lower limit of the setting range of that number of revolutions cannot be set, so the user mistakenly uses the sewing machine. It is possible to prevent the problem that the sewing machine cannot be sewn well because the sewing machine is broken by setting the rotation speed higher than the guaranteed rotation speed of the above, or the rotation speed is set too low.

Further, according to the sewing machine control device of the sixth invention, since the input state of each input signal input to the sewing machine control device can be displayed on the display device, a measuring instrument such as a tester as in the conventional case. Without checking the input state of each input signal using, the sewing machine needle position detector and motor speed detector connected to the sewing machine controller, each input device such as the variable speed pedal is operating normally, Alternatively, it can be easily confirmed whether the connection is normal.

Further, according to the sewing machine control device of the seventh invention, the output state of each output signal output from the sewing machine control device can be displayed on the display device. Connected to the sewing machine control device without checking the output status of each output signal by using the solenoid drive device for the operations such as thread trimming, thread loosening, thread wiping, and reverse stitching, and the sewing machine presser automatically. It is possible to easily confirm whether or not each output device such as a press-up device for raising to normal is operating normally or is connected normally.

Further, according to the sewing machine control device of the eighth aspect of the invention, since it is possible to make a setting for prohibiting the transition to a setting mode for making various settings that define the operation of the sewing machine, the user makes an erroneous switch operation. By doing so, it is possible to prevent a transition to a setting mode that is not released to the user. In addition, since it is possible to freely set whether or not the transition to the setting mode is prohibited, it is possible to easily set whether or not to release the individual setting mode to the user for various setting modes.
