FIG. 2 is a block diagram of one embodiment of the present invention. The same elements as those in FIG. 1 are designated by the same reference numerals as those in FIG. A ten key 3a, a clear key 3d, and a set key 3e forming the mode designating switch 2 and the keyboard 3 are connected to the bus line 2 of the CPU 20 via the input interface 15.
Connected to 1. In addition to the above, the keyboard 3 is a ring counter 3 that makes one cycle with an oscillator 3f, AND gates 3g and 3h, and 3 counts.
ring counter 3k has shift key 3b
-Operated by 3c. Specifically, the countdown input of the ring counter 3k receives the output pulse of the oscillator 3f via the AND gate 3g, and the countup input of the ring counter 3k receives the output pulse of the oscillator 3f via the AND gate 3h. When the shift key 3b is pressed, the AND gate 3g is opened and the ring counter 3k is advanced in the reverse direction. When the shift key 3c is pressed, the AND gate 3h is opened and the ring counter 3k is advanced in the forward direction. It The count value of the ring counter 3k is also connected to the bus line 21 via the input interface 15. Next, dy number indicator 4, channel number indicator 6,
Data display 8, earned number display 10, indicator 5
The 7, 9, 11, and 12 are connected to the bus line 21 via the output interface 22. Next, 23 is a readable / writable memory device (hereinafter abbreviated as RAM) that stores various control data for each dynam for each type of control data, and 24 is RAM.
A data register for storing data to be read and written in 23,
Reference numeral 25 is a row address register for designating a row address of the RAM 23, and 26 is a column address register for designating a column address of the RAM 23. The RAM 23 has addresses specified in a matrix, the row address corresponds to the die number and the column address corresponds to the channel number, and when the numerical value of the ring counter 3k is 0, the row address is changed by the numerical value input from the ten-key 3a. , When the numerical value of the ring counter 3k is 1, the column address is designated by the numerical value input from the ten-key 3a. The data register 24 is connected to the data line D in the bus line 21. Next, reference numeral 30 is a die number reading device for reading the die number of the die attached to the press device. The die number reading device 30 uses, for example, a photoelectric sensor group to provide a reflection mark provided on an identification plate attached to a predetermined portion of the die. It is detected, and the number is identified by the operation pattern of this photoelectric sensor group. The output of the number reading device 30 is connected to the bus line 21 via the input interface 31. Further, 32 is an output interface for transferring control data to an external device, and the output interface 32 is connected to a printer 33 or a CRT 35 which is an example of an external device in addition to the press control device 32. Next, the operation of this embodiment will be described with reference to the above matters and the flowchart of FIG. First, the control data for each dy number is stored in the RAM 23 for each channel number according to the type of control data. When writing the control data, the writing mode is designated by the mode designation switch 2 on the operation panel 1. When the write mode is designated, the CPU 20
Turns on the indicator lamp 11. In the initial state, the ring counter 3k shows some count value, and the CPU 20 reads the count value of the ring counter 3k when the mode designating switch 2 designates the write mode. Then, the CPU 20 turns on the indicator lamp 5 when the count value of the ring counter 3k is 0, the indicator lamp 7 when the count value of the ring counter 3k is 1, and the count value of the ring counter 3k is 2.
At this time, each of the indicator lights 9 is turned on to inform the operator of the count value of the ring counter 3k. In this embodiment, since the RAM 23 is accessed with the die number as the row address and the channel number as the column address, it is necessary to specify the row address and the column address of the RAM 23 when writing data. First, the shift keys 3b and 3c of the keyboard 3 are operated to specify the row address, and the count value of the ring counter 3k is set to zero. As mentioned above, pressing the shift key 3b causes an AND gate 3g.
The pulse generated by the oscillator 3f is added to the countdown input via the ring counter 3k and the ring counter 3k is stepped in the reverse direction. Also, when the shift key 3c is pressed, the pulse generated by the oscillator 3f is input via the AND gate 3h. In addition, the ring counter 3k is stepped forward. Then, the lighting positions of the display screens 5, 7 and 9 change corresponding to the count value of the ring counter 3k, and when the indicator keys are lit, the count value of the ring counter 3k becomes 0 when the shift keys 3b and 3c are released. Stop at. Now, the operator designates the dynum to which the control data is to be written by using the ten keys 3a and the set key 3e. If the count value of the ring counter 3k is 0, the CPU 20
Reads numerical data input from the ten-key 3a via the input interface 15 via the data line D, and when the set key 3e is pressed, the numerical data is set in the row address register 25. Therefore, the number is i-th (here, i is RAM2
When the row address of 3 is 0 to m, various control data regarding the mold of natural numbers 0 to m are stored in the RAM 23.
Will be stored in the i-th row for each type of control data. The dynamometer set in the row address register 25 in this manner is displayed on the dynamometer indicator 4 via the data line D-output interface 22. When the number is set as described above, the operator selects the type of control data to be written from the shift key 3
b.3c, the numeric keypad 3a, and the set key 3e. In the present embodiment, the type of control key is identified as a channel number. When the shift key 3c is pressed once, the ring counter 3k
Is stepped, its count value becomes 1, and the CPU 20 turns on the indicator lamp 7. Subsequently, the operator designates a channel number indicating the type of the control data to be written with the ten keys 3a and the set key 3e. If the count value of the ring counter 3k is 1, the CPU 20
Reads numerical data input from the numeric keypad 3a via the input interface 15 via the data line D, and sets the numerical data in the column address register 26 when the set key 3e is pressed. If the channel number set at this time is the j-th (here, j is a natural number of 0 to n when the column address of the RAM 23 is 0 to n), i × of the RAM 23
Address j is addressed. The channel number thus set in the column address register 26 is displayed on the channel number display 6 via the data line D-output interface 22. When the die number and the channel number are set as described above, the operator inputs the contents of the control data of the j-th channel for the i-th die by using the shift keys 3b and 3c, the ten keys 3a and the set key 3e. When the shift key 3c is pressed once, the ring counter 3k
Is stepped, the count value becomes 2, and the CPU 20 turns on the indicator lamp 9. When the count value of the ring counter 3k is 2 and the matrix address has already been set, the CPU 20 accesses the i × j address of the RAM 23 by the matrix address set in the row address register 25 and the column address register 26. Then, the control data which has already been set is read out, and this control data is displayed on the data display 8 via the data line d and the output interface 22. Subsequently, the operator inputs the contents of the j-th channel control data relating to the i-th die by using the ten-key 3a and the set key 3e. The CPU 20 reads the numerical data input from the numeric keypad 3a via the input interface 15 via the data line D, and when the set key 3e is pressed, this control data is set in the data register 24, and i × of the RAM 23 is set.
Update the contents of address j. At this time, the control data set in the data register 24 is displayed on the data display 8 via the data line D-output interface 22. In this way, the control data for the j-th channel whose die number is the i-th die is stored in the address i × of the RAM 23, and the same operation is performed for all the channels thereafter, so that the die number can control all the i-th die. The control data is stored for each column address in the RAM 23 where the row address is designated by i. Further, by repeating the above operation for all die numbers, all control data for all dies are RA
It is stored in M23. All control data stored in this way will be stored in the R
It is held in the AM 23. On the other hand, the mold device used in the present embodiment has an identification plate attached to a predetermined portion thereof, and the identification plate displays a die number by a pattern of a reflection mark, for example. During press work, the operator switches the mode changeover switch 2 to the reading side, and the CPU 20 turns on the indicator lamp 12. Now, the dye number reading device 30 photoelectrically reads the pattern of the reflection mark on the identification plate to identify the dye number. On the other hand, when the mode designating switch 2 is switched to the reading side, the CPU 20 reads the die number identified by the die number reading device 30 via the input interface 31-data line D, and sets the read die number in the row address resist 25. The numerical value set in the row address register 25 at this time is displayed on the operation dynamometer display 10 via the data line D-output interface 22. The CPU 20 sequentially reads the various control data stored in each column of the i-th row of the RAM 23 from the data register 24 while sequentially updating the set value of the column address register 26, and the data line D-output interface 32.
To the press controller 33, and the press controller 33 controls a press device value (not shown) according to the transmitted control data. At this time, the control data may be transmitted to and output from the printer 34 and the CRT 35. Next, FIG. 4 is a block diagram showing another embodiment of the present invention, and the same elements as those in the embodiment shown in FIG. 2 are designated by the same reference numerals as those in FIG. The features of the embodiment shown in FIG. 4, that is, the differences from the embodiment shown in FIG. 2 are as follows. In the case of the embodiment shown in FIG. 2, the row and column addresses are designated by the key input when writing the control data. However, in the embodiment of FIG. 4, the row address and the column address are specified. An example is shown in which a counter for setting is provided, and the row address and the column address are automatically updated by sequentially stepping up the address setting counter in accordance with the control data setting operation. Specifically, in addition to the embodiment shown in FIG. 2, the embodiment shown in FIG. 4 has a column address that advances the set values of the one-shot circuit 27 and the column address register 26 that generate a pulse when triggered. A counter 28 and a row address counter 29 for advancing the set values of the row address register 25 are provided. The column address counter 28 and the row address counter 29 are initially reset when the write mode is designated, and the one-shot circuit 27 is set. It is triggered by pressing the key 3a. Also, the row address counter 2
9 and the column address counter 28 are each constituted by a ring counter. Therefore, when writing the control data, first, the RAM 2
The 0th row and 0th column of 3 are addressed, and the column address is incremented by pressing the set key 3e after keying in the control data. Then, when the setting of the control data for all the columns for the 0th row is completed, the row address counter 29 is incremented by the carryover signal of the column address counter 28, and the 0th column of the 1st row is addressed. It Control data is stored for all matrices by repeating the same operation.

【effect】

As described above, according to the present invention, once the control data is input, the die number is read from the identification plate provided on the die, the control data corresponding to the die number is read from the RAM 23, and the press control device is read. Since it is transmitted to each other, it is not necessary to key in the sex fish data every time the mold is changed. Also, when inputting the control data, it is sufficient to operate only the numeric keypad and the accompanying 2 and 3 keys while looking at the numerical display.
