Description

  The present invention relates to a molding machine such as an injection molding machine or a die casting machine, and more particularly to a configuration of a molding condition setting device attached to the molding machine.

  Molding machines such as injection molding machines and die casting machines are equipped with molding condition setting devices that set molding conditions. Prior to the operation of the molding machine, the input section of this molding condition setting device is operated. It is necessary to input the required molding conditions. However, since the molding conditions of the molding machine are diverse, skill is required to set the molding conditions, and it is difficult for an unskilled person to efficiently set all necessary setting items.

  In order to alleviate the difficulty of such molding condition setting work, the applicant of the present application sequentially displays a plurality of molding condition setting screens on which various columns of molding conditions are displayed on the display unit, On the molding condition setting screen, a molding machine including a molding condition setting device that displays a color of an input field for molding conditions to be input has been proposed (see, for example, Patent Document 1). Specifically, a molding condition automatic setting mode (molding navigation mode) is stored in the storage unit, and when the operator selects the mode, the control unit displays the display screen of the display unit in the molding condition automatic setting mode. While switching to the first setting screen, the setting item display field in the first setting screen is displayed in color, and the next display request displayed in the first setting screen by the operator operating the input unit When the column is selected, the display screen of the display unit is switched to the second setting screen in the molding condition automatic setting mode, and the operation of displaying the setting item display column in the second setting screen in color is finally performed. It repeats until the setting screen.

  In the molding machine previously proposed by the applicant of the present application, when the molding condition automatic setting mode of the molding condition setting device is activated, a plurality of setting screens necessary for setting the molding conditions are displayed on the display unit in a predetermined order. In addition, since the display field of the setting item to which the molding condition in each displayed setting screen should be input is displayed in a color different from the surroundings, the operator is displayed in the display field of the setting item displayed in color. The setting of the molding conditions can be completed simply by inputting predetermined set values in the order described. Therefore, the molding conditions necessary for the operation of the molding machine can be set without any special skill, and the molding conditions can be set efficiently and reliably.

JP 2012-011660 A

  By the way, the molding machine previously proposed by the applicant of the present application can select whether or not to clear the previous set value displayed on the display unit after starting the molding condition automatic setting mode. . The reason is that when “Clear the previous set value” is selected, the set values of each setting item displayed on the display section are all switched to “0”, so the operator can set a new set value. This is because it is not necessary to check the previous set values one by one when performing the work, and the setting work of the molding conditions can be performed efficiently. In addition, when “Do not clear the previous set value to zero” is selected, the previous set value is displayed as it is on the display unit, so the operator refers to the previous set value displayed on the display unit, This is because it is only necessary to input the set values for the necessary setting items, and the setting operation of the molding conditions can be performed efficiently. Which one to select depends on the preference of the operator, the production plan of the molded product, and the like. For example, when the manufacture of a similar molded product is started after the manufacture of one type of molded product is completed, it is more advantageous to select “Do not clear the previous set value to zero”, and different types of raw resin are used. When starting to manufacture the molded product, it is more advantageous to select “clear the previous set value to zero”.

  In addition, the molding machine previously proposed by the applicant of the present application is capable of performing an end operation (navigation end operation) of the molding condition automatic setting mode during execution of the molding condition automatic setting mode. This is because the molding condition setting operation can be performed again as necessary. However, in the molding machine previously proposed by the applicant of the present application, since the previous set value is rewritten to 0 at the stage of selecting “clear the previous set value to zero”, the “previous set value is cleared to zero”. When the molding condition is set in the molding condition automatic setting mode and the operator performs an end operation of the molding condition automatic setting mode during the execution, the setting value input by this setting work is Although it is stored in the storage unit, the previous set value set before the zero clear disappears. Therefore, when the operator uses the molding condition automatic setting mode again to set the next molding condition, the operator must continue the next setting work using the setting value entered in the current setting work. However, it is impossible to set the molding conditions of this time while referring to the previous set values.

  In other words, the molding machine previously proposed by the applicant of the present application loses the previous setting value when selecting `` Clear the previous setting value '' in the molding condition automatic setting mode, this time using the previous setting value This makes it impossible to set the molding conditions, so that the operator's needs cannot be fully met, and there is room for improvement in this respect.

  The present invention has been made in view of this point, and the object of the present invention is that even when “clear previous setting value to zero” is selected after starting the molding condition automatic setting mode, An object of the present invention is to provide a highly convenient molding machine that can restore set values and can meet various needs of operators.

  In order to solve the above problems, the present invention provides a control unit in which a molding condition automatic setting mode is stored, a display unit that displays a plurality of screens used for setting molding conditions in the molding condition automatic setting mode, In a molding machine including an input unit that performs a required input operation on the display screen of the display unit, when an operator selects the molding condition automatic setting mode by operating the input unit, the control unit After the automatic condition setting mode is activated, the previous molding condition setting value is saved in the save area of the storage unit provided in the control unit, and the operator inputs the input during the subsequent execution of the molding condition automatic setting mode. In this case, the previous molding condition setting value saved in the saving area is readable and retained even when the process of operating the unit and selecting the process for clearing the previous molding condition setting value to zero is selected.

  According to such a configuration, when the molding condition automatic setting mode is selected, the control unit saves the previous molding condition setting value in the storage area of the storage unit, and then the operator sets the previous molding condition setting value. Even when the zero clear process is selected, the previous molding condition setting value saved in the save area can be read out. Therefore, even after the operator has selected the process of clearing the previous molding condition setting value to zero, even when the molding condition automatic setting mode is in the middle of the molding condition setting operation in the molding condition automatic setting mode, Since the previous molding condition setting value can be restored, it is possible to meet the needs of the operator who wants to input this molding condition setting value using the previous molding condition setting value, and molding conditions in the molding condition automatic setting mode. The convenience of setting work can be enhanced.

  In the molding machine having the above configuration, the molding condition automatic setting mode end button is displayed on the molding condition setting screen displayed on the display unit, and an operator operates the input unit to display the molding condition automatic setting mode end button. When the end button is selected, the save end button and the non-save end button are displayed in a selectable manner on the setting screen where the end button is operated, and the operator operates the input unit to select the save end button. The molding condition automatic setting mode is overwritten with the previous molding condition setting value stored in the storage unit after the molding condition setting value set during execution of the current molding condition automatic setting mode is over, When the operator operates the input unit and selects the non-save end button, the molding condition setting value set during execution of the current molding condition automatic setting mode is stored in the storage unit. And without overwriting the previous molding condition setting values, characterized by terminating the molding condition automatic setting mode.

  According to this configuration, when the end button of the molding condition automatic setting mode is operated on each setting screen from the first setting screen to the final setting screen, the save end button is displayed in the setting screen in which the end button is operated. And the non-save end button is displayed so that it can be selected, so that the latest setting conditions can be saved in the storage unit as needed, and the previous setting values can be maintained. The condition setting operation can be made simpler.

  In the molding machine configured as described above, when the operator selects the molding condition automatic setting mode by operating the input unit, the control unit automatically sets the molding condition display screen. In addition to switching to the first setting screen of the mode, the display field of the setting item to which the molding conditions in the first setting screen should be input is displayed in color, and the operator operates the input unit to operate the first When the next display request field displayed in the first setting screen is selected, the display screen of the display unit is switched to the second setting screen in the molding condition automatic setting mode, and the second setting screen The control of displaying the setting item display field for inputting the molding condition in the color is performed up to the final setting screen.

  According to this configuration, when the molding condition automatic setting mode is activated, a plurality of setting screens necessary for setting the molding conditions are displayed on the display unit in a predetermined order, and the molding conditions in each displayed setting screen are input. The display column for the setting item to be displayed is displayed in color (displayed in a color different from the surroundings so that the operator can easily see it), so the operator can automatically set the molding condition setting item and its input procedure. Can know. Therefore, the molding conditions necessary for the operation of the molding machine can be set without any special skill.

  According to the present invention, when the molding condition automatic setting mode is activated, the previous molding condition setting value is saved in the save area of the storage unit, so the previous molding condition setting value is cleared to zero during the molding condition automatic setting mode. Even when the selection is performed, the previous molding condition setting value can be restored as necessary, and the convenience of the molding condition setting operation in the molding condition automatic setting mode can be enhanced.

In addition to the “next” button 122 and the “navigation end” button 123, a “return” button 124 is also displayed on each screen after the option list screen 130 in FIG. When the “Next” button 122 displayed on the initial screen 120 of molding navigation is selected, the option list screen 130 of FIG. 8 is displayed on the display unit 30. When the “Next” button 122 displayed on the option list screen 130 in FIG. 8 is selected, the calculation screen 140 in FIG. 9 is displayed on the display unit 30. Similarly, when the “Next” button 122 displayed on the calculation screen 140 is selected, the replacement screen is displayed on the display unit 30, and when the “Next” button 122 is selected on the replacement screen, the temperature screen is displayed on the display unit 30. When the “Next” button 122 is selected on the temperature screen, the mold opening / closing screen is displayed on the display unit 30. When the “Next” button 122 is selected on the mold opening / closing screen, the injection plasticizing screen is displayed on the display unit 30. When the “next” button 122 is selected on the injection plasticizing screen, the replacement screen is displayed again on the display unit 30. At this stage, setting of molding conditions is completed.

  The mold opening / closing screen displays a mold opening / closing option selection button, an air selection button, and a core selection button. When the operator operates one of the selection buttons, the type of the selected selection button is displayed. In response, either the mold opening / closing option screen, the air screen, or the core screen is displayed on the display unit 30. In addition, the injection plasticizing screen displays an injection plasticizing option selection button and a plasticizing auxiliary selection button, and when an operator operates one of the selection buttons, depending on the type of the operated selection button, Either the injection plasticizing option screen or the plasticizing auxiliary screen is displayed on the display unit 30.

  As described above, the “return” button 124 is displayed on each screen after the option list screen 130, and the display screen of the display unit 30 is selected when the operator selects the “return” button 124 on one screen. Can be returned to the previous display screen. For example, when the “return” button 124 displayed on the screen 30 is selected while the option list screen 130 of FIG. 8 is displayed on the display unit 30, the display screen of the display unit 30 is displayed from the option list screen 130. 5 is returned to the initial screen 120 of the molding navigation. Thereby, the molding conditions performed on the previous screen can be corrected at any time.

  In addition, as described above, the “navi end” button 123 is displayed on each screen after the initial screen 120 of the molding navigation, and the operator selects the “navi end” button 123 on one screen, The molding condition setting operation in the molding condition automatic setting mode can be stopped. When the “navi end” button 123 is operated, the display screen of the display unit 30 is switched to the menu screen 110 of FIG. As a result, it is possible to perform the molding condition setting operation not depending on the molding condition automatic setting mode.

  When the “navi end” button 123 is operated, the control unit 24 asks the operator to select whether or not to save the molding conditions set in the molding navigation before executing the molding navigation end procedure. Thereby, the operativity of a molding machine can be made very favorable. The operation for determining whether or not to preserve the molding conditions will be described later in detail with reference to the drawings.

  Hereinafter, details of the molding condition setting operation using the “molding navigation” will be described in more detail with reference to FIGS.

  When “molding navigation” is selected from the menu screen 110 shown in FIG. 3, the molding navigation initial screen 120 shown in FIG. 5 is displayed on the display unit 30. On the initial screen 120, “Start molding navigation. Stop automatic mode. Press“ Next ”to start molding navigation. Press“ End navigation ”to end molding navigation and MENU. A guidance sentence 121 “Go to screen”, “Next” button 122, and “End navigation” button 123 are displayed. In addition, when “molding navigation” is selected from the menu screen 110, a button for reading the guidance text 121 is displayed on the initial screen 120 instead of the configuration in which the guidance text 121 is automatically displayed on the initial screen 120. Alternatively, the guidance sentence 121 may be displayed on the initial screen 120 only when the operator operates this button. As described above, when “molding navigation” is selected from the menu screen 110, the previous molding condition file 232 stored in the internal memory 23 a of the storage unit 23 is saved in the save area 235.

  When the “Next” button 122 displayed on the initial screen 120 is operated, an inquiry screen 125 “Would you like to set it to 0?” Is displayed on the initial screen 120 as shown in FIG. “Set to 0” means to set the previous set value to zero for each item for which the set value is set using molding navigation. When “OK” on the inquiry screen 125 is selected, all the previous set values are cleared to zero in principle. However, in the present embodiment, inquire about the monitoring time, monitoring torque, and number of EJ of the low pressure mold clamping area displayed on the mold opening / closing / EJ screen, and the heater set temperature and hopper down temperature displayed on the temperature setting screen. Even when “OK” on the screen 125 is selected, the previous setting value is not set to zero. As described above, when the previous setting values for the predetermined setting items are cleared to zero, the operator can input the predetermined setting items to be input in accordance with the molding navigation. There is no need to check the set value, and the setting operation of the molding conditions can be streamlined. When “CANCEL” on the inquiry screen 125 is selected, all previous setting values are maintained, and when setting new setting values, the previous setting values can be used as necessary. Conditions setting work can be streamlined.

  On the other hand, when the “navi end” button 123 displayed on the initial screen 120 is operated, an inquiry screen 126 “Do you want to finish molding navigation?” Is displayed on the initial screen 120 as shown in FIG. When “OK” of 126 is selected, the molding navigation is terminated, and the menu screen 110 shown in FIG. 3 is displayed on the display unit 30. If “CANCEL” is selected on the inquiry screen 126, the molding navigation is continued and the option confirmation screen 130 shown in FIG. 8 is displayed. On the option confirmation screen 130, a list 131 of preset options is displayed. In the example of FIG. 8, it can be seen from the option confirmation screen 130 that “temperature control zone” and “number of temperature control boards” in environment setting 1 are set as options. In addition to the “next” button 122 and the “navigation end” button 123, a “return” button 124 is displayed on the option confirmation screen 130.

  When “Next” is selected on the option confirmation screen 130, a calculation screen 140 shown in FIG. 9 is displayed on the display unit 30. On the calculation screen 140, a heading column 202 for “clamping force calculation” and a heading column 203 for “stroke calculation” are displayed below the title column 201, and below the heading column 202 for “clamping force calculation”. As a setting item display field, a projection area setting field 204 is displayed, and further below that is a list selection button 205 for average resin pressure in the mold and a mold clamping force for instructing to start calculation of the mold clamping force. A calculation button 206, a mold clamping force calculation value display field 207 for displaying the calculated mold clamping force, and a "link to replacement screen" button 208 for reflecting the mold clamping force calculation value on the replacement screen are displayed. The On the other hand, a product weight setting field 210 is displayed as a setting item display field below the “stroke calculation” heading field 203, and further below that, a resin material list selection button 211 and a necessary item are displayed. A required stroke calculation button 212 for instructing the start of stroke calculation, a required stroke calculation value display field 213 for displaying the calculated required stroke, and an “injection plasticization” for reflecting the required stroke calculation value on the injection plasticization screen. A “link to screen” button 214 is displayed.

  When the display on the display unit 30 is switched to the calculation screen 140, first, a heading column 202 for “clamping force calculation”, a projection area setting column 204, a mold clamping force calculation button 206, and an interlock button 208 on the exchange screen. The product weight setting field 210, the necessary stroke calculation button 212, and the link button 214 to the injection plasticization screen are displayed in different colors from the surroundings. The operator refers to this color display and sets the projected area of the molded product using the input unit 40 in the projected area display field. When the projected area of the molded product is set, the color display in the projected area setting column 204 is canceled, and the set value is displayed in the projected area display column 204. Therefore, the operator can know that the input of the set value in the projected area display field 204 has been completed. Next, the operator presses the in-mold average resin pressure list selection button 205 to display the in-mold average resin pressure candidates on the display screen, and selects an appropriate one from the display. The selected value is displayed in the display column 205 for the average resin pressure in the mold. Next, when the calculation button 206 is selected, the mold clamping force is automatically calculated and displayed in the mold clamping force calculation display field 207. Thereby, the mold clamping force calculation is completed. Thereafter, the interlock button 208 is pressed on the replacement screen to reflect the calculated mold clamping force calculation on the replacement screen.

  When the “next” button 122 displayed on the calculation screen 140 is pressed after the mold clamping force calculation is completed, the color display of the “clamping force calculation” heading column 202 disappears and the “stroke calculation” heading column 203 is displayed. Is displayed in color. Next, the operator uses the input unit 40 to input the product weight of the molded product in the product weight display field 210. When the product weight of the molded product is input, the color display in the product weight setting column 210 is canceled and the set value is displayed in the product weight display column 210. Therefore, the operator can know that the input of the set value to the product weight display field 210 has been completed. Next, the operator presses the resin material list selection button 211 to display the resin material candidates on the display screen, and selects an appropriate one from the display. The selected material name is displayed in the resin material display column 211. Next, when the calculation button 212 is selected, the necessary stroke is automatically calculated and displayed in the necessary stroke display field 213. Thereby, the stroke calculation is completed. Thereafter, the interlock button 214 is pressed on the injection plasticization screen, and the obtained stroke calculation is reflected on the injection plasticization screen.

  In this way, when there are two or more molding condition setting fields to be input on one screen, each time the molding condition setting in one setting field is completed, the color display of the setting field is displayed. When the release is performed, the operator can know that the setting of the molding conditions for the setting column whose color display has been canceled is completed, and thus it is possible to reliably prevent omission of necessary molding conditions. When the operator operates the “return” button 124 displayed on the calculation screen 140 after the setting of the molding conditions using the calculation screen 140 is completed, the heading column 203 of “stroke calculation” is first displayed in color. When the “return” button 124 is operated again, the heading column 202 of “clamping force calculation” is displayed in color. This facilitates correction of the previously set molding conditions.

  After setting the molding conditions necessary for mold clamping force calculation and stroke calculation using the calculation screen 140, when the operator operates the “navi end” button 123 displayed on the calculation screen 140, the calculation screen 140 displays As shown in FIG. 10, an inquiry screen 127 of “Do you want to register settings?” Is displayed. When the operator selects “Yes (register setting)”, the current setting value set using the molding navigation is overwritten and saved in the storage unit 23. Accordingly, when the molding condition is set using the molding navigation next time, the operator can perform the molding condition setting operation using the current set value overwritten and stored in the storage unit 23. Conditions can be set efficiently. In addition, when the operator selects “No (do not register setting)”, the current setting value set using the molding navigation is not overwritten and saved in the storage unit 23, and the previous setting value is stored in the storage unit. 23. Thus, the operator does not need to confirm the previous set value every time when the molding condition is set using the next molding navigation, so that the molding condition can be set efficiently. Whether “Yes” or “No” is selected depends on the preference of the operator, the production plan of the molded product, and the like. That is, by displaying the inquiry screen 127 on the calculation screen 140, the molding condition setting method can be diversified, and the use of the molding machine can be made convenient.
