Two simple programs are input to the NC device 3 in advance and stored in the memory 5. The number of bits for outputting the program number of the machining program is 4 in the BCD code.
This is done with 16-bit output in digits.

Therefore, in order to call the above two simple programs, a total of 17 bits including the four digits of the BCD code of 16 bits and the calling bit 11 (1 bit) of the calling strobe described above are used.

The two simple programs have program numbers "7" as shown in FIGS.
777 "and a simple content of only" M390 ", and a simple program number of" 8888 "and a content of only" M391 ".

The main feature of the present invention is that the above two simple programs are called by the input device 15 of the external sequencer 7 before the normal machining program is called by the external sequencer 7 and the program number is normally set to the NC device. No. 3 is to check whether or not it has been output.

With the input device 15 of the external sequencer 7,
First, when a program number “7777” is input and a command is given to call up the content of “M390”, the external sequencer 7 outputs a DI / O signal to the NC via the relay 21 corresponding to 16 bits of the relay unit 9. Output to the device 3. At this time, in each relay 21, bit No. 1 of the digit A of the BCD code as shown in FIG.
4 correspond to the first digit number "7" of the program number. The bit No. whose sum of the numerical values in the column of the standard of the decimal number matches the number “7” is bit No. 1,
Bits Nos. 1 to 3 are ON, and the other bits No. 4 are OFF.

Further, bit No. 5 of the digit B of the BCD code
8 correspond to the second digit number "7" of the program number. The bit No. whose sum of the numerical values in the column of the guideline of the decimal number matches the number “7” is bit No. 5,
6 and 7, bit Nos. 5 to 7 are turned on, and other bit No. 8 is turned off.

Hereinafter, similarly, the bit of the digit C of the BCD code
Nos. 9 to 12 correspond to the third digit number "7" of the program No. The bit number for which the sum of the numerical values in the column of the standard of the decimal number matches the number “7” is the bit number.
9, 10, 11 and these bit Nos. 9 to 11 are ON
, And the other bit No. 12 is turned off. further,
Bit Nos. 13 to 16 of the digit D of the BCD code correspond to the fourth digit number "7" of the program No. 1
The number obtained by summing up the numerical values in the column of the standard of the 0-base number is the number “7”
Are the bit Nos. 13, 14, and 15. Bits 13 to 15 are turned on, and the other bit No. 16 is turned off.

In response to the command to call the program number “7777”, the contents “M39” of the program number “7777” stored in the memory 5 of the NC unit 3 in advance.
“0” is called via the call bit 11 and is displayed on the display device 17 of the external sequencer 7. Therefore,
By confirming the displayed contents by the operator, it is confirmed whether or not the machining program with the program number “7777” has been executed.

Next, when a program number "8888" is input and a command is issued to call up the contents "M391", the external sequencer 7 relays the DI / O output similarly to the above-mentioned program number "7777". It is output to the NC device 3 via each relay 21 corresponding to 16 bits of the unit 9. At this time, in each relay 21, as shown in FIG.
Nos. 1 to 4 correspond to the first digit number "8" of the program No. The bit number for which the sum of the numerical values in the column of the standard of the decimal number coincides with the number “8” is the bit number.
This bit No. 4 is turned ON, and the other bits N
o.1 to 3 are OFF.

In the same manner, the bit number corresponding to the number "8" in the second digit when the sum of the numerical values in the column of the reference of the decimal number is similarly set.
Is bit No. 8, and this bit No. 8 turns ON,
Other bits Nos. 5 to 7 are turned off. The bit number for which the sum of the numerical values in the column for the decimal number is the same as the third digit number “8” is bit No. 12, and this bit No. 1
2 turns ON, and the other bits No. 9 to 11 turn OFF. The bit number for which the total number of the numerical values in the column of the decimal number coincides with the fourth digit number “8” is bit No. 16, and this bit No. 16 is turned on, and the other bit No. 1 is turned on.
3 to 15 are OFF.

In response to the command for calling the program number “8888”, the contents “M39” of the program number “8888” stored in the memory 5 of the NC unit 3 in advance.
"1" is called through the call bit 11, is displayed on the display device 17 of the external sequencer 7, and the displayed contents are checked by the operator to check whether the machining program of the program number has been executed. .

As described above, the two simple programs “7
When “777” and “8888” are executed, the relays 21 of the bit Nos. 1 to 16 corresponding to the 16 bits of the relay unit 9 are turned on as shown in FIG.
Or, it is easily and quickly confirmed whether or not the switch is turned off only with the simple contents of “M390” and “M391”.

When it is confirmed that all the bits have been turned ON or OFF, the external sequencer 7 outputs a command for executing a regular machining program to the NC unit 3 so that normal plate material machining does not malfunction without fail. Executed in normal operation.

If two simple programs "7777"
When at least one of the plurality of bits is not turned ON or OFF by calling “8888” and “8888”, the next normal machining program is not operated and the relay 21 of the relay unit 9 is operated. For example, alarm 2 as a reporting device for reporting that a failure has occurred
Since the operator is notified by the warning of 3 and the display of the display device 17, the occurrence of processing defects is avoided, and the reliability of the plate processing machine 1 is improved.

The present invention is not limited to the above-described embodiment of the present invention, but can be embodied in other modes by making appropriate changes.

[0037]

As will be understood from the above description of the embodiments of the present invention, according to the first aspect of the present invention, by executing a plurality of simple programs, each of the bits corresponding to all bits of the relay unit is executed. Whether the relay has been turned ON or OFF can be easily and quickly confirmed only by displaying the simple contents of the plurality of simple programs. Therefore, if it can be confirmed that all bits have been turned ON or OFF, the external controller outputs a command to execute a normal machining program to the machining machine controller, thereby ensuring normal operation of the plate material without malfunction. Can be performed by driving.

According to the second aspect of the present invention, the effect is the same as that of the first aspect. By executing a plurality of simple programs, it is determined whether or not each relay corresponding to all bits of the relay unit is turned on or off. Can be easily and quickly checked simply by displaying the simple contents of a plurality of simple programs. Therefore, if it can be confirmed that all bits have been turned ON or OFF, the external controller outputs a command to execute a normal machining program to the machining machine controller, thereby ensuring normal operation of the plate material without malfunction. Can be performed by driving.

According to the third aspect of the present invention, by calling a plurality of simple programs, at least one of all bits of the relay unit is turned on or off.
When the FF is not performed, the operator is notified by the notification device that a failure has occurred in the relay of the relay unit without operating the next normal processing program. The reliability of the machine can be improved.
