  On the other hand, FIG. 3 shows a block circuit of the controller 4 to which the display 2 is connected. The controller 4 basically includes hardware such as a CPU and an internal memory, has a computer function of storing various software, and has a function of controlling the entire injection molding machine Mo. Reference numeral 21 denotes a CPU, and a bus line 24 using a local bus such as a PCI bus is connected to the CPU 21 via an internal bus 22 and a chip set 23 to form an HMI (Human Machine Interface) control system 4h. To do.

  Further, an internal memory (internal storage means) 25 such as a hard disk is connected to the bus line 24. The internal memory 25 has a data area 25d in which various data can be written, and a program area 25p for storing various programs. Further, the display 2 described above is connected to the bus line 24 via the display interface 26, and an external memory driver 28 is connected via the input / output interface 27. The external memory driver 28 includes at least a USB port. Therefore, various external memories (external storage means) 29 such as a USB memory can be attached to the external memory driver 28 to write and read various data (including programs).

  On the other hand, a bus line 31 similar to the bus line 24 is connected to the chip set 23 to constitute a PLC (programmable logic controller) control system 4p. For this reason, the bus line 31 is connected with an input / output interface 33 for giving the switching data Di obtained from various switches to the CPU 21 and giving the control command data Do obtained from the CPU 21 to the corresponding actuator. Connected to the input / output interface 35 is an analog detection signal Si obtained from sensors, which is analog-to-digital converted and applied to the CPU 21 and a control command data obtained from the CPU 21 is digital-to-analog converted to a corresponding actuator. To do. Thus, a predetermined feedback control system and an open loop control system are configured.

  Therefore, in the program area 25p of the internal memory 25 described above, the PLC program and the HMI program are stored, and various processing programs for executing various arithmetic processes and various control processes (sequence control) are stored. The PLC program is software for realizing the sequence operation of various processes in the injection molding machine Mo, the monitoring of the injection molding machine Mo, etc., and the HMI program is the setting and display of operation parameters of the injection molding machine Mo, the injection molding machine. This is software for realizing the display of Mo operation monitoring data. These software are constructed as a unique architecture of the injection molding machine Mo on which the controller 4 is mounted.

  In addition, the processing program to be stored particularly includes a display processing program 25pd for executing the display method according to the present embodiment, and the controller 4 uses the display processing program 25pd to use the injection molding machine Mo. A setting function Fs for setting one or two or more monitoring items C1... With an increase or a decrease with the progress and a monitoring target value Eo1... Or a monitoring target auxiliary value Es1... Based on the monitoring target value Eo1. Prepare. Further, in the display processing program 25pd, when at least the size E1 of the monitoring item C1 to be monitored when the injection molding machine Mo is used reaches the monitoring target value Eo1 or the monitoring target auxiliary value Es1. As shown, an icon for displaying a specific icon 3 indicating that the monitoring target value Eo1 or the monitoring target auxiliary value Es1 has been reached on the key surface Kzf of the screen switching key Kz or the like corresponding to the monitoring item C1 or the like. When the program pdx related to the icon display task processing for realizing the display function Fi and the size E2 of the monitoring item C2 reach the monitoring target value Eo2 or the monitoring target auxiliary value Es2, the icon 3 is displayed. Is displayed on the display screen Vz... Corresponding to the screen switching key Kz..., The message 5 corresponding to reaching the monitoring target value Eo2. A message pd related to the message display task processing for realizing the message display function Fm, and the second display indicating that the message content corresponds to the specific icon 3 on the display unit 6 displaying the message 5 or in the vicinity thereof. A program pdz related to the second icon display task process for realizing the second icon display function Fis for displaying the icon 3s is included.

  Next, the display method according to the present embodiment will be specifically described with reference to FIGS.

  First, the setting function Fs of the controller 4 sets in advance one or two or more monitoring items C1... That increase or decrease as the use of the injection molding machine Mo progresses, and the monitoring target value Eo1 in each monitoring item C1. Set…. In this embodiment, in addition to the monitoring target values Eo1..., A case where monitoring target auxiliary values Es1... Based on the monitoring target values Eo1.

  In this case, “component life” can be applied as a representative monitoring item C1 that decreases with the progress of use of the injection molding machine Mo. FIG. 5 shows a maintenance screen (display screen) Vz. The maintenance screen Vz includes a maintenance inspection management display unit 51, a system setting display unit 52, a program management display unit 53, a support tool display unit 54, and the like. In addition to having various display units related to the maintenance, a component life management display unit 55 is provided. The component life management display unit 55 includes a remaining life graph display unit 55s that displays an image of the remaining life of each component.

  The remaining life graph display portion 55s is extracted and shown in FIG. The remaining life graph display section 55s includes a plurality of components to be monitored, specifically, "board", "injection ball screw", "liquid crystal panel", "battery", "sequencer power supply", and "inverter". The remaining lifetimes are displayed as bars by bars B1 to B6, respectively. In the remaining life graph display portion 55s, Ls is an unused line, Lm is a caution notification line, and Le is a life end line. Thereby, for example, in the case of the bar B2 indicating the remaining life of the injection ball screw, when replacing with a new one, the entire section between the unused line Ls and the life end line Le is displayed by, for example, the blue bar B2. , It gradually shortens with the progress of use. Then, as shown in FIG. 6, the bar B <b> 2 is color-changed and displayed in yellow, for example, by cutting a preset caution notification line Lm. Further, when the bar B2 reaches the end of life line Le, the display becomes zero, and thereafter, the bar B2 becomes longer in the minus direction as B3s. At this time, the bar B2 is displayed in red, for example. . Although the bar B2 related to the injection ball screw has been described, the other bars B1, B3 to B6 are also displayed in the same manner. Since the lifetime of each component is known in advance as the usable time and the like, the usable time and the like are set when the component is replaced. Therefore, normally, by switching to the maintenance screen Vz, the remaining life of each component can be confirmed by the remaining life graph display section 55s. In FIG. 5, reference numeral 55d denotes a remaining life numerical value display section showing the remaining life as a numerical value, and displays an absolute value of the remaining life, a predicted life end date, and the like.

  In the above example, since the component life is set as the monitoring item C1, the size of the life end line Le described above is the monitoring target value Eo1, and the caution notification line Lm is the monitoring target auxiliary value Es1 based on the monitoring target value Eo1, respectively. Is set. Either one or both of the monitoring target value Eo1 and the monitoring target auxiliary value Es1 may be used. In this embodiment, the case where both are used is illustrated. Further, when a specific icon 3 to be described later is displayed, yellow is displayed when the monitoring target auxiliary value Es1 is reached, and red is displayed when the monitoring target value Eo1 is reached.

  In addition, “maintenance check date” can be applied as the monitoring item C2. As described above, the maintenance screen Vz shown in FIG. 5 is provided with the maintenance / inspection management display unit 51, and the maintenance / inspection management display unit 51 can manage the due date of maintenance / inspection. The maintenance inspection management display unit 51 is extracted and shown in FIG. The maintenance / inspection management display unit 51 particularly includes a scheduled execution date display unit 51 s displaying “scheduled execution date”, and a specific scheduled execution date is set in the scheduled execution display unit 51 s. Accordingly, the number of days (the number of remaining days) is set as the size E2 of the monitoring item C2, the date before a predetermined number of days set in advance as the monitoring target auxiliary value Es2, and the scheduled date of execution as the monitoring target value Eo2.

  Furthermore, a message display unit 6 based on the message display function Fm described above is provided in a part of the maintenance / inspection management display unit 51. Thereby, when the size E2 of the monitoring item C2 (maintenance inspection date) reaches the monitoring target value Eo2 or the monitoring target auxiliary value Es2, the monitoring screen Cz is displayed on the display screen Vz corresponding to the screen switching key Kz displaying the icon 3. A message 5 corresponding to reaching the target value Eo2 or the monitoring target auxiliary value Es2 is displayed. Therefore, if such a message display function Fm is provided, the detailed contents can be confirmed by touching the screen switching key Kz to switch to the corresponding display screen Vz. In other words, the conventional support message window display is not displayed immediately, but is displayed after touching the screen switching key Kz... Displaying the icon 3, so that the screen being monitored is hidden by the window display or the like. There is an advantage that detailed contents can be surely confirmed while eliminating defects.

  In addition, based on the second icon display function Fis, the message display unit 6 or its vicinity (illustrated in the vicinity of the message display unit 6) has a second message indicating that the message content corresponds to the specific icon 3. Icon 3s is displayed. If such a second icon display function Fis is provided, the operator can quickly display the message content corresponding to the specific icon 3 when the screen switching key Kz... Is touched to switch to the corresponding display screen Vz. And there is an advantage that can be confirmed surely.

  On the other hand, “production amount” can be applied as a representative monitoring item C3 that increases with the use of the injection molding machine Mo. FIG. 12 shows the production amount management display unit 71 from which a part of the production information screen (display screen) Vh has been extracted. The production quantity management display unit 71 displays a specific quantity related to the production quantity. For example, if the target production quantity is input and set in the target production quantity display unit 71o displayed for each molded product to be produced, If the target production amount is set as the monitoring target value Eo3, and the quantity slightly in front of the target production amount is input and set to the monitoring production amount display unit 71s as the monitoring production amount, the monitoring production amount is set to the monitoring target auxiliary value Es3. Set as

  As described above, if at least one of the above-described component life (C1), maintenance inspection date (C2), and production (C3) is included in the monitoring item C1. It is optimal from the viewpoint of appropriately monitoring increase or decrease over time. These monitoring items C1, C2, and C3 are only examples, and other items that increase or decrease as the use of the injection molding machine Mo (production machine M) can be similarly used as monitoring items. is there.

  Next, processing during use of the injection molding machine Mo will be described according to the flowcharts shown in FIGS. 8 and 9 with reference to the drawings.

  When the injection molding machine Mo is used, if the size E1 of the monitoring item C1 to be monitored reaches the monitoring target value Eo1 and / or the monitoring target auxiliary value Es1 by the icon display function Fi, the monitoring item C1. A specific icon 3 indicating that the monitoring target value Eo1 and / or the monitoring target auxiliary value Es1 has been reached, that is, the icon 3 as a notification icon is displayed on the key surface Kzf. Perform the process. In the case of the example, as shown in FIG. The icon 3 is displayed at a lower left position of the rectangular key surface Kzf.

  Hereinafter, a specific processing procedure will be described. The example shows the case of component life (monitoring item C1).

  First, the case where only the monitoring target value Eo1 is set for the monitoring item C1 will be described with reference to the flowchart shown in FIG. Now, it is assumed that the injection molding machine Mo is in an operating state (step S1). During operation (molding), the size (remaining life) E1 related to the component life is monitored by the controller 4 (steps S2 and S3). In addition, as shown in FIG. 4, the temperature screen Vd (upper stage) and the process monitoring screen Vg (lower stage) are displayed on the display surface 2v of the display 2 in two stages up and down, and the operator is monitoring the process. Is assumed. Therefore, in this case, as shown in FIG. 4, in the key display portion Xk, the screen switching key Kd and the screen switching key Kg are respectively selected. In the illustrated example, each screen switching key Kd... Is changed in display color (or display density) by being selected, and in particular, a screen switching key corresponding to the temperature screen Vd displayed on the upper stage of the display surface 2v. Each density (relative density) of the screen switching key Kg corresponding to Kd and the process monitoring screen Vg displayed in the lower stage is displayed at a different density.

  On the other hand, it is assumed that, during such monitoring, for example, the life of the injection ball screw ends and the bar B2 indicating the remaining life reaches the life end line Le (step S4). Since this state means that the size E1 of the monitoring item C1 has reached the monitoring target value Eo1, as shown in FIG. 4 (FIG. 1), the key surface Kzf of the screen switching key Kz corresponding to the monitoring item C1. The icon 3 indicating that the monitoring target value Eo1 has been reached is displayed in red (step S5). In this case, the component life (monitoring item C1) is managed on the maintenance screen Vz, and since the screen switching key Kz corresponds to the maintenance screen Vz, the icon 3 is displayed on the screen switching key Kz.

  Thereby, the operator can know that the component to be monitored has reached the replacement time. At this time, the component life (monitoring item C1) is not an unexpected error or trouble of the injection molding machine Mo, but is an item that gradually decreases with the use of the injection molding machine Mo. Therefore, it is necessary to immediately replace the part. There is no need to monitor the currently displayed temperature screen Vd and the process monitoring screen Vg, or when the production lot is settled, it can be confirmed at an arbitrary time by the operator's judgment.

  If the operator touches the screen switching key Kz on which the icon 3 is displayed for confirmation, the maintenance screen Vz shown in FIG. 5 corresponding to the screen switching key Kz is displayed on the display surface 2v. (Steps S6 and S7). Therefore, the operator can confirm that the life of the injection ball screw has ended by using the remaining life graph display section 55s shown in FIG. 6, and therefore, the remaining life graph display such as parts replacement (ball screw replacement) is performed. A corresponding process for the state of the unit 55s can be performed (steps S8 and S9). The display of the icon 3 may be canceled based on the timing at which the screen switching key Kz is touched, or may be canceled based on completion of corresponding processing such as component replacement (ball screw replacement). Good (steps S7, S9).

  As described above, when the display of the icon 3 is canceled, the screen switching key Kz on which the icon 3 is displayed is touched, or if the corresponding processing after the touch of the screen switching key Kz is completed, the icon 3 is displayed. If the release is performed, an appropriate display timing for the icon 3 can be set, so that an unnecessary display as a notification icon can be avoided.

  By the way, in the case of the monitoring item C2 (maintenance check date), the operator can confirm the message (support message) 5 when touching the screen switching key Kz to switch to the maintenance screen Vz. That is, since the maintenance inspection management display unit 51 described above is displayed on the maintenance screen Vz, the maintenance inspection management display unit 51 can be confirmed on the maintenance screen Vz. In this case, based on the message display function Fm, the message display unit 6 shown in FIG. 7 displays a message 5 corresponding to reaching the monitoring target value Eo2, and based on the second icon display function Fis, A second icon 3 s corresponding to the specific icon 3 is displayed in the vicinity of the message display unit 6. Therefore, the conventional support message window display is not displayed immediately, but is displayed after the touch of the screen switching key Kz... Displaying the icon 3, so that the screen being monitored is hidden by the window display or the like. While eliminating, it is possible to confirm the detailed contents with certainty. Further, the operator can quickly and surely confirm the message content corresponding to the specific icon 3. The display of the message 5 can be similarly displayed when the monitoring target auxiliary value Es2 described below is reached. Note that the message content at this time is different from that in the case of the monitoring target value Eo2.

  The case where only the monitoring target value Eo1 is set for the monitoring item C1 (C2) has been described above, but both the monitoring target value Eo1 and the monitoring target auxiliary value Es1 may be set. Next, the case where both the monitoring target value Eo1 and the monitoring target auxiliary value Es1 are set will be described with reference to the flowchart shown in FIG. Now, the injection molding machine Mo is in an operating state, and during operation (molding), the size (remaining life) E1 related to the component life (monitoring item C1) is monitored by the controller 4 and the display 2 is displayed. The temperature screen Vd (upper stage) and the process monitoring screen Vg (lower stage) shown in FIG. 4 are displayed in the upper and lower stages on the surface 2v, and the state where the operator is monitoring the process is the case of the flowchart shown in FIG. (Steps S11, S12, S13).

  On the other hand, it is assumed that during such monitoring, the life of the injection ball screw decreases and the bar B2 indicating the remaining life reaches the caution notification line Lm (step S14). Since this state means that the size E1 of the monitoring item C1 has reached the monitoring target auxiliary value Es1, as shown in FIG. 4 (FIG. 1), the key surface of the screen switching key Kz corresponding to the monitoring item C1. In Kzf, an icon 3 indicating that the monitoring target auxiliary value Es1 has been reached is displayed in yellow (step S15).

Therefore, the operator can confirm that the life of the injection ball screw has been completed by using the remaining life graph display portion 55s shown in FIG. A corresponding process for the state can be performed (steps S18, S19, S20). The display of the icon 3 displayed in red may be canceled based on the timing at which the screen switching key Kz is touched, or based on completion of corresponding processing such as component replacement (ball screw replacement). May be canceled.

  Therefore, according to the display method (display device 1) of the injection molding machine Mo according to this embodiment, when the injection molding machine Mo is used, the size E1 of the monitoring item C1 is monitored, and the monitoring item C1. When the magnitude E1 reaches the monitoring target value Eo1 and / or the monitoring target auxiliary value Es1, the monitoring target value Eo1 and / or the monitoring target auxiliary value Es1 is displayed on the key surface Kzf of the screen switching key Kz corresponding to the monitoring item C1. Since the specific icon 3 indicating that the value has been reached is displayed, regardless of which display screen Vd is used (displayed), the operator can monitor the screen corresponding to the screen switching key Kz. It is possible to easily and accurately confirm that the size E1 of the item C1 has reached the monitoring target value Eo1 and / or the monitoring target auxiliary value Es1, and even in this case, the main table being displayed It is possible to avoid the problem that the screen Vd ... is hidden. In addition, the specific icon 3 can function as a notification icon. Therefore, the operator can confirm the specific state at an arbitrary time, for example, when the production is finished or when the main display screen Vd... In addition, when the monitoring target auxiliary value Es1 is set, the contents can be predicted to some extent, so that appropriate preparations can be made in advance such as ordering new parts, preparing for inspection, preparing for production switching, etc. It can contribute to improvement of convenience and improvement of work efficiency. Moreover, since it is applied to the injection molding machine Mo as the production machine M, it is an important part used in the injection process of the injection molding machine Mo and management of the life is important. For example, the life of an “injection ball screw” or the like It is optimal from the viewpoint that it is possible to accurately grasp and to perform appropriate parts replacement.
