[Problems to be solved by the invention]

By the way, in the digital switch or the like of the operation panel in the control device of the conventional injection molding machine described above, the position of each display digit is appropriately set as needed.

For example, if the number of display digits is three, if the integer part is set to two digits and one digit after the decimal point, the displayed value will be 0.0 to 99.9, and it is possible to handle numbers in the range of 0 to 100 in 0.1 increments Become. Also, if one digit of the integer part is set to two digits after the decimal point, the displayed value will be 0.00 to 9.99, and will be 0 in increments of 0.01.
It is possible to handle in the range of ~ 10.

However, in the conventional digital switch of the control device,
Since the numerical value is set by the operation button or the like corresponding to the display digit position, the digit position is fixed at a preset digit position for mutual correspondence, and there are various inconveniences in using.

For example, considering the handling of three significant digits, it is necessary to handle numbers in the range of 0 to 100 in increments of 0.01 in order to cover numbers such as 1.23 and 12.3. It is necessary to display digits such as 01.23 to 12.30 using digits. For this reason, the cost increases with an increase in the number of digits, and the installation space increases due to the increase in size. On the other hand, there is a problem that an invalid digit is generated in a part of the set display digits and cannot be used effectively.

In particular, in the case where various numerical data can be taken in a fixed panel with emphasis on listing, an increase in the number of display digits in the digital switch becomes a major obstacle.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a control device for an injection molding machine capable of ensuring a sufficient range and accuracy of displaying or setting numerical data with a small number of display digits.

[Action]

In such an embodiment of the present invention, numerical data in the register is displayed by the numerical display unit, and numerical values for each digit can be operated by the numerical operation unit. At this time, the digit position including the decimal point of the numerical value display section and the numerical value operation section can be simultaneously moved by the digit position moving means, so that the association between the display section and the operation section is secured, and the integer section of the operated numerical data is stored. When the number of digits increases, the digit position shifts to the right, and when the number decreases, it shifts to the left. Therefore, the display digits can be effectively used by the set number of significant digits, and the display accuracy can be secured while expanding the display range of the numerical data that can be handled, thereby achieving the above object. .

Note that the digit position is shifted right (upper digit 1 → 10, lower digit)
In the case of (0.1th place → 1st place), the numerical value in the lower 0.1 place is lost. In this case, rounding or finishing is appropriately performed, and the result is sent from the numerical value setting means 33 to the register. Returning to 31, the consistency of the process is maintained.

On the other hand, to the numerical value setting means 33 and the display control means 34, a digit position moving means 30 for simultaneously moving the display digit position and the operation digit position is connected. Shift control means 36 is provided.

Among these, the numerical data determination means 35 reads the numerical data in the register 31 and compares the numerical data with the determination reference value preset in accordance with each of the buttons 21 to 24 identified by the numerical value setting means 33, thereby operating the numerical value. This is to determine a change in the number of digits of the integer part of the data. Here, the judgment reference value is a unit number 0.1, 1, 10 that can be displayed in two digits and a combination thereof.
11,20,9.0,9.9 etc. are adopted.

Further, the digit shift control means 36 includes a numerical data determination means.
Based on the determination result of 35, the necessity of moving the display digit position is determined, and if necessary, numerical value setting means 33 and display control means 34
Output the shift command.

Note that the display ON / OFF command from the control circuit 3 is output from the input / output control means 32 to the display control means 34, and only when the display is ON, the numerical value display unit 10 is enabled to perform display. Further, the operation ON / OFF command from the control circuit 3 is output from the input / output control means 32 to the numerical value setting means 33 so that the operation of each button is accepted and the numerical operation section 20 is enabled only in the operation ON state. It is configured.

In the setting / display switch 5 of the present embodiment configured as described above, the numerical data R input from the input / output control means 32 to the register 31 is converted into a two-digit number by the display control means 34, and the upper digit is displayed. The lower digit is displayed on the display 12 on the display 12, and the operation for the buttons 21 to 24 is awaited.

In this state, if any button is operated, the numerical data determination means 35 checks the numerical data R in the register 31 and
The digit position is determined based on the determination reference value according to the button information from the numerical value setting means 33. Subsequent to this determination, the numerical value setting means 33 performs an operation of adding or subtracting the numerical data R in the register 31 in the current operation unit set for the operation button. Here, when it is determined in the determination that the digit position needs to be moved when the numerical data R is added or subtracted, the digit shift control means 36 sends a left or right shift command to the display control means 34 and the numerical value setting means 33. Based on this shift command, the display control means 34 changes the digit position of each of the indicators 11 and 12, and the numerical value setting means 33 changes the operation unit.

Further, if the numerical data R is 10 or more and less than 11, the lower digit operation unit 1 in the decimal point OFF state is subtracted from the numerical data R (process 77), and the display digit and the operation unit are shifted to the left (process 7).
8, the same as the processing 68 described above), and in this state, the numerical data R is changed to L
Display on ED2 and LED1 (process 79).

For this reason, as shown in FIG. 8 (E), if the decrease button 23 is pressed when the current display is 11, the value becomes 1 by the processes 75 to 76.
The display is reduced to 10. Then, press button 23 to process
77-79 reduces the value by 1 and adds a decimal point to display 9.0. When the button 23 is further pressed, the value is reduced by 0.1 by processes 73 to 74, and the display becomes 8.9.
