The injection molding machine M is driven and controlled by the control device 1. The control device 1 of the injection molding machine M is provided with a processor for arithmetic processing, an input / output device, a storage device, and a display device in the same manner as conventionally known devices. The present invention described as a functional block in FIG. 2 can be configured by using the hardware of the control device 1.

  FIG. 2 is a functional block diagram of the display device 2 using a touch panel in the control device 1 of the injection molding machine. The display device 2 includes a display unit 40 and a display control unit 50 connected to the display unit 40. The display unit 40 is installed on an upright cover 62, and the display control unit 50 is configured using the hardware of the control device 1 built in the machine base Mb (see FIG. 1).

  The display unit 40 includes a touch panel 41 and a screen display unit 42. The touch panel 41 is transparent and is mounted on the screen display unit 42. For this reason, the operator can visually recognize the image displayed on the screen display unit 42 through the transparent touch panel 41. The touch panel 41 is provided with means for detecting a position when a finger contacts the surface. Note that the touch panel 41 is a well-known detection unit, and thus detailed description thereof is omitted. The screen operation panel 43 is arranged below the screen display unit 42, and the screen operation panel 43 is provided with various buttons for screen selection.

  The display control unit 50 includes an input window display data memory 51, an input signal control unit 52, an image memory 53, a screen display control unit 54, and a screen display data memory 55. The input signal control unit 52 is a control unit that connects the touch panel 41 and the screen display control unit 54. The input signal control unit 52 controls the touch panel 41 to capture an input signal from the touch panel 41, and displays position information on the screen as a screen display control unit. 54 is handed over.

  The input window display data memory 51 is an input window display data memory in which screen display data of an input window to be displayed on the screen of the screen display unit 42 is stored when setting values such as molding conditions are input. The input window display data memory 51 stores step switch type key window display data 51a and ten key type key window display data 51b. The screen display data memory 55 is a screen display data memory that stores display items such as setting items such as molding conditions and setting numerical values.

  The screen display control unit 54 performs necessary calculation processing from the position information in response to touch input on the touch panel 41, and receives an input window in response to a screen display request from the screen operation panel 43 attached to the display device 2. Data for screen display is read from the display data memory 51 and the screen display data memory 55, transferred to the image memory 53, and the image data transferred to the image memory 53 is displayed on the screen display unit 42 of the display unit 40.

  Further, the screen display control unit 54 selects a step switch type key window or a numeric keypad type key window display by executing a program that embodies the flowchart of the algorithm according to the present invention shown in FIG. The information is displayed on the screen display unit 42 of the display unit 40.

  First, by operating an operation button on the screen operation panel 43 (see FIG. 2), an image corresponding to the operated button is displayed. When the ejector operation setting button is pressed, an ejector operation setting screen is displayed on the screen display unit 42 of the display unit 40. The input items for ejector operation setting displayed on the screen display unit 42 include numerical input items such as the ejector reverse position, the ejector reverse speed, the ejector reverse stop time, and the ejector advance position shown in FIG.

  FIG. 3 is a diagram illustrating an example of a numeric keypad key window and an example of a step switch type key window. The numeric keypad key window 10 and the step switch type key window 20 are displayed so as to be superimposed on a part of the ejector operation setting screen displayed on the screen display unit 42 of the display unit 40.

  FIG. 3A is an example of a display screen of the numeric keypad key window 10. The ten key type key window 10 directly inputs a numerical value by touching the ten key displayed on the screen display unit 42. Therefore, the input data display unit 11, the ten key 12, the cancel key 13, the + input key 14, the message display unit 15, It has a current position transfer key 16, a switch 17 for switching to a step switch type key window, and an input key 18. The current position transfer key 16 displays the data of the current position stored in the storage device of the control device of the injection molding machine M of the selected input item on the input data display unit 11 of the numeric keypad window 10. This key is used to command storage. The data displayed on the input data display unit 11 is confirmed by touching the input key 18 and is taken into a control device (not shown) of the injection molding machine.

  The ten keys 12 are “7”, “8”, “9”, “4”, “5”, “6”, “1”, “2”, “3”, “0”, “−”, “ . " The cancel key 13 is erased from the data at the rightmost digit of the data displayed on the input data display unit 11 toward the left. The + input key 14 is a key for adding a preset numerical value to the data displayed on the input data display unit 11. The message display unit 15 displays a message that the data input using the numeric keypad 12 is out of the allowable range.

  FIG. 3B is an example of a display screen of the step switch type key window 20. Since the step switch type key window 20 is input by touching a key for increasing / decreasing a numerical value for each digit, switching to an increase key 21, an input data display unit 22, a decrease key 23, an input key 24, and a numeric keypad key window. A switch 26 is provided.

  The increase key 21 is a key for inputting data in increments of +1, +0.1, and +0.01. In contrast to the increase key 21, the decrease key 23 is a key for inputting data in increments of -1, -0.1, and -0.01. Since the set numerical value can be changed only in a step-like manner in this way, there are fewer setting mistakes than the numeric keypad type. The input data display unit 22 displays data input using the increase key 21 and the decrease key 23. The input key 24 is a key for confirming data input using the increase key 21 and the decrease key 23. Similar to the message display unit 15, the message display unit 25 displays a message when the input data is out of range.

  Since the current position transfer key may greatly change the current set value during machine operation, the current position transfer key is not displayed in the step switch type key window 20 for which fine adjustment setting is intended.

  It is mainly a change in the setting value of the position data that an erroneous change of the setting value of the input item during operation of the injection molding machine may cause a dangerous state. For example, if the injection position, the measurement position, the mold operation position, and the eject position are changed incorrectly, the mold may be damaged or the resin material may be scattered. When changing such settings during machine operation, it is better to give priority to the step switch type key window, which has fewer setting errors than the numeric keypad type.

FIG. 4 is a diagram for explaining the priority display setting of the step switch type key window during machine operation.
As shown in FIG. 4A, as the input item 200 to be input to display the step switch type key window with priority, as shown in FIG. 4A, the ejector retract position 204, the ejector retract speed 206, the ejector retract stop time 208, the ejector advance position 210, There are an ejector advance speed 212, an ejector advance stop time 214, and the like. Then, corresponding to each input item, “Yes” or “No” is input as to whether or not to perform priority display of the step switch type key window as shown in the figure. Alternatively, as shown in FIG. 4B, only the input items for which priority display of the step switch type key window is performed may be selected and stored.

  As described above, the setting item that preferentially displays the step switch type key window may specify that the step switch type key window is given priority in a table partitioned for each setting item, or for display control. They may be listed and described in the program. In the case where the priority is given to the step switch type key window in the table, it may be set in advance at the time of shipment from the factory, or may be set by the user when operating the machine. By storing the data set as a table in the image display data memory 55 (see FIG. 2), the step switch type key window can be preferentially displayed.

  Here, the operation of the machine will be described. Machine operation includes manual operation and automatic operation, but the operation status that is dangerous due to incorrect setting value input is only during manual operation, automatic operation, injection, mold operation Alternatively, when it is limited only during ejection, the step switch type key window 20 may be displayed only in the limited machine operating state. For example, when a setting item is selected that is not dangerous due to a setting change error except during injection, a step switch type key window may be displayed during injection, and any input window may be displayed except during injection.

  Further, although the numeric keypad key window 10 has been selected, an item for which the priority display setting of the step switch type key window 20 during machine operation is valid is touched during the machine operation. Is displayed, the input window displayed after the machine is stopped may be automatically returned to the numeric keypad display window, or the step switch type key window switched during the machine operation may be displayed as it is.

FIG. 5 is a flowchart showing an algorithm for setting priority display of a step switch type key window during machine operation. Processing based on this algorithm is performed at predetermined intervals. Hereinafter, it demonstrates according to each step.
[Step SA100] It is determined whether or not the numerical input item has been touched. If the touch operation has been performed, the process proceeds to Step SA101. If the touch operation has not been performed, the process of this control cycle ends.
