Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a sewing machine control device that performs control according to data stored in a storage medium.

[Prior art]

Conventionally, there has been a device of this type as shown in FIG.

In FIG. 1, numeral 1 is an operation panel for setting various operations of the sewing machine, and 2 is an input/output I10 board, which controls input and output of various data based on instructions from a processor (CPU) 3. 4'+4b is a memory for storing data processed by the CPU 3, 5 is an I10 boat with the same functions as I10 boat 2, 6 is a controlled section including the sewing machine body, and 1L7a and 7b are display circuits with the same configuration. %R1 and R2 are resistors, TR is a transistor, and PD is a light emitting diode, whose emitted light colors differ from each other in the display circuit 7''+7b.The memory 4& consists of a ROM and a RAM, and the memory 4b consists of a ROM.

Next, the operation will be explained. CPU3 is Memo I74
Various operations are performed according to program data stored in &. Depending on the settings on the operation panel 1, the XY table and sewing machine in the controlled section 6 are controlled according to the operating speed of the controlled section 6 or the pattern data stored in the memory 4b.

Now, if the sewing machine operator (not shown) makes a mistake in the setting operation on operation panel 1, for example, the data stored in data 4b may be expanded and set to a value that exceeds the movement limit of the X-Y table. In this case, the CPU 3 notifies the operator by lighting the display circuit 7a through the I10 boat 2. Further, if the data memory 4b is not set at a predetermined position, the CPU 3
The display circuit 7b is lit through the boat 1 to notify the operator.

Conventional sewing machine control devices are configured as described above, and have the function of notifying the operator of incorrect settings due to erroneous operation, but they do not have a means to notify of malfunctions of internal electronic components, etc., so the operator cannot detect malfunctions of the machine itself. The drawback was that it required a great deal of time and effort to make a decision.

[Summary of the invention]

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and improves usefulness and maintainability by manually selecting and executing either the sewing mode or the failure diagnosis mode. It is an object of the present invention to provide a sewing machine control device that can be improved.

[Embodiments of the invention]

An embodiment of the present invention will be described below.

In FIG. 2, the same symbols as in FIG. 1 indicate the same parts,
8 has a switch SW, and is a mode selector for selecting sewing mode S or failure diagnosis mode T; 9 is an interface connected to CPU 3, for example, the known R8-232C;
Interface 10 is a printer connected to CPO 2 through interface 9.

Now, the mode selector 8 is set to sewing mode SK, and I1
It is assumed that a high level mode signal M is input to the 0 port 2. In this case, the controlled section 6 is controlled by the CPU 3 to perform predetermined sewing, and if there is an abnormality in any part of the device, the display circuits 7a and 7b are turned on as described above. When the mode selector 8 is set to the failure diagnosis mode T and a low level mode signal M is input to the 110 port 2, the CPU 3 uses the program stored in the memory 4a to operate the memory 4a, 4b according to the flowchart shown in FIG. , I10 boat 5th class,
Performs diagnostic processing for each part of the device.

That is, in the RAM test, for example, a predetermined pattern (not shown) of data is written in the memo IJ4a to be diagnosed, and the data is read into the CPU 3 again to check whether it matches the written information. In the I10 test, for example, a predetermined pattern of data is output to the I10 boat 2 to be diagnosed, the data of the output boat is switched to the input boat by a program, and then the data is input to the CPU 3, so that both data match. Find out if it is.

The above results are stored in the print information storage RAM in the interface 9 and then output to the printer IO. Therefore, the operator only has to carry out predetermined troubleshooting based on the information printed out by the printer 10, and the time required for taking countermeasures can be shortened.

1. In the above embodiment, the results of the failure diagnosis are output to the printer, but the same effect can be obtained by displaying them on a single display circuit or outputting audio. In addition, there is no need to switch between the actual sewing mode and the failure diagnosis mode using the mode selector, and it is possible to have the failure diagnosis program resident in the actual sewing mode program as long as it does not affect the processing speed. . Further, it is not necessary to provide one printer for each sewing machine, and the printer may be connected through a connector only when a failure diagnosis is required.

〔Effect of the invention〕

As described above, 1.According to the present invention, since the sewing machine control device is configured to be able to selectively execute the actual sewing mode or the failure diagnosis mode, troubleshooting by the operator is facilitated, the device can be made inexpensive, and the accuracy can be improved. This allows for high quality sewing.
