Description

BACKGROUND OF THE INVENTION Area of ​​the invention

[0001] The present invention relates to a display device and a display system of an injection molding machine. Related technology

[0002] Traditionally, an injection molding machine is an industrial machine that injects and shapes materials such as resin. Before operating an injection molding machine, certain parameters are set. The machine then operates according to these settings.

[0003] The values ​​set for the injection molding machine are determined through trial and error. This means that the values ​​are determined by actually operating the machine using predefined values ​​and adjusting them. In this case, several display windows are shown on a display device on the injection molding machine, and the operator switches between them to set different values.

[0004] Therefore, it is desirable that the display device of the injection molding machine be configured to be suitable for displaying multiple windows. A screen display control device is proposed as a device for displaying multiple windows, between which switching is performed (see, for example, JP 2006-298671A). This device comprises a main screen and a sub-screen and displays multiple windows between which switching is performed (see, for example, JP 2006-298671A).

[0005] Furthermore, a control device for an injection molding machine is known from EP 3 006 183 A1. This control device controls the display of images on a display unit. It divides the display unit into a first display area and a second display area. When a command to scroll vertically is received, and a first display image is shown in the first display area and a second display image is shown in the second display area, the control device scrolls the first and second display images synchronously while maintaining their relative positions.

[0006] From US patent 2012 / 0242702A1, methods and devices for selectively displaying a user interface for a telephone application are also disclosed. In particular, a change in the display mode of a device with multiple screens can be determined. SUMMARY OF THE INVENTION

[0007] The screen display control device disclosed in JP 2006-297 671 A displays multiple windows on the main screen and the sub-screen. Therefore, it is possible to improve the setting efficiency when adjusting values ​​for a machine tool such as an injection molding machine.

[0008] When pre-setting values ​​related to the operation of an injection molding machine, sometimes too many windows are displayed for setting these values. Therefore, it is preferable for a window that is highly relevant to a selected main screen to be displayed on a sub-screen. Furthermore, it is preferable for a window displayed on a sub-screen to be selected and displayed automatically.

[0009] It is an object of the present invention to provide a display device and a display system for an injection molding machine that are suitable for automatically displaying a window highly relevant to a window displayed on a sub-screen.

[0010] (1) The present invention provides a display device for an injection molding machine suitable for displaying two or more windows and comprising: a display unit having at least one main display unit and one sub-display unit; an input unit receiving an input relating to the selection of a window to be displayed on the display unit; and a display control unit selectively controlling the window to be displayed on the display unit according to the input into the input unit, wherein the display control unit switches a window to be displayed on the main display unit according to the input into the input unit.

[0011] In the display device of the injection molding machine according to (1), the display device further comprises a counting unit which counts the number of repetitions of the display of a window on the main display unit, and the display control unit displays a window on the sub-display unit where the number of repetitions of the display counted by the counting unit is highest.

[0012] (2) The present invention also provides a display device for an injection molding machine, suitable for displaying two or more windows, comprising: a display unit having at least one main display unit and one sub-display unit; an input unit receiving an input relating to the selection of a window to be displayed on the display unit; and a display control unit selectively controlling the window to be displayed on the display unit according to the input to the input unit.In the display device of the injection molding machine, the display device further comprises a counting unit that counts the number of repetitions of the selection of a window selected for display on the main display unit according to a window displayed on the main display unit, and the display control unit displays a window for which the number of repetitions of the selection is highest among windows selected in the past for display on the main display unit according to a window displayed on the main display unit on the sub-display unit.

[0013] (3) In the display device of the injection molding machine according to (1), the display control unit preferably performs such a control that a window can be displayed on the sub-display unit when the number of repetitions of the display counted by the counting unit is equal to or greater than a predetermined number of repetitions.

[0014] (4) In the display device of the injection molding machine according to (1), the input unit preferably retrieves identification information to identify an operator who operates the injection molding machine, and the display control unit controls a window to be displayed on the sub-display unit depending on an operator identified by the identification information.

[0015] (5) In the display device of the injection molding machine according to (1), the display device preferably further comprises an operating state determination unit that determines an operating state of the injection molding machine, the counting unit that counts the number of repetitions of the display of a window on the main display unit for each of the operating states, and the display control unit that switches a window to be displayed on the sub-display unit depending on the operating state.

[0016] (6) The present invention provides a display system comprising: several of the display devices according to any one of points (1) to (5) and a management device connected to the several display devices, the management device comprising a window selection unit which selects a window to be displayed on the sub-display unit of each of the display devices according to a window displayed on the main display unit of each of the several display devices, and the display control unit displays the selected window on the display device.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following are, with reference to the Fig. Sections 1 to 4 describe a display device 1 and a display system of an injection molding machine 100 according to examples. First, an overview of the injection molding machine 100 and the display device 1 of the injection molding machine 100 is described.

[0019] The injection molding machine 100 is a machine that, for the production of a product (a molded part), injects, for example, molten resin at a high temperature into a mold and then cools the resin. When a product is manufactured using the injection molding machine 100, the machine can produce a product in a more suitable condition through operation based on preset values ​​(settings).

[0020] The settings are pre-set and determined by actually operating the injection molding machine 100 before the start of mass production. The setting and determination of the settings are carried out, for example, by an operator M controlling the injection molding machine 100 entering values ​​and making further inputs to determine the settings. When the settings are entered and determined, the display device 1 of the injection molding machine 100 receives the input of the setting values ​​from the operator M by sequentially displaying several windows that show the status of the injection molding machine 100 according to the operator M's selections. Furthermore, the display device 1 of the injection molding machine 100 also receives the input for determining the setting values ​​from the operator M.In this way, the display device 1 and the display system of the injection molding machine 100 according to the examples and embodiments of the present invention can assist the operator M in setting and determining the setting values. [First example]

[0021] Next, with reference to the Fig. 1 to 4 describe the display device 1 of the injection molding machine 100 according to a first example. The display device 1 of the injection molding machine 100 according to the present example is a device suitable for displaying two or more windows. As in Fig. As shown in Figure 1, the display device 1 of the injection molding machine 100 is configured, for example, to be integrated into the injection molding machine 100. The display device 1 of the injection molding machine 100 shows the operator M of the injection molding machine 100 an operating status, setting values, and the like of the injection molding machine 100 using several windows. As shown in Fig. As shown in Figure 2, the display device 1 of the injection molding machine 100 comprises a display program storage unit 30, a display content storage unit 40, several display units 10, an input unit 20 (a selection input unit 21) and a display control unit 50. In the context of this example, "window" denotes an image displayed on the display device 1.

[0022] The display program storage unit 30 is, for example, an additional storage medium such as a hard drive or memory. The display program storage unit 30 contains several programs for displaying windows for each window.

[0023] The display content storage unit 40, for example, is an additional storage medium such as a hard drive or memory, and the display content storage unit 40 stores a display sequence of shown windows as data. As in Fig. As shown in Figure 3, the display content storage unit 40 stores data, for example, in a sequence (a selection sequence) in which the operator selects M window numbers (identification numbers of windows).

[0024] The display unit 10 is, for example, a display or a liquid crystal device. In the present example, several display units 10 are provided. The several display units 10 comprise at least one main display unit 11 and one sub-display unit 12. More precisely, the several display units 10 comprise, by way of example, a main display unit 11 and a sub-display unit 12.

[0025] The main display unit 11 is a device that displays, for example, a window recently selected by the operator M. More precisely, the main display unit 11 is a device that displays a window recently selected by the operator M among several windows.

[0026] The sub-display unit 12 is a device that, for example, displays windows that were previously shown on the main display unit 11.

[0027] The input unit 20 is an input device that receives input. The input unit 20 receives the input relating to the selection of a window to be displayed on the display unit 10. More precisely, the input unit 20 receives the input relating to the selection of a window to be displayed on the display unit 10 from the operator M of the injection molding machine 100. In the present example, the input unit 20 is configured, for example, as a position detection device (as a touch-sensitive control panel) arranged in the main display unit 11. Furthermore, in the present example, the input unit 20 receives the input relating to the selection of a window to be displayed on the main display unit 11. More precisely, the input unit 20 receives the input relating to the selection of a window to be displayed on the main display unit 11 from the operator M of the injection molding machine 100.In the following description, the input unit 20, which receives the input to select a window to be displayed on the main display unit 11, is also referred to as the "selection input unit 21".

[0028] The display control unit 50 is implemented, for example, when an arithmetic device such as a (not shown) processor operates. The display control unit 50 selectively controls a window to be displayed on the display unit 10 according to the input to the input unit 20.

[0029] The display control unit 50 reads a display program corresponding to a window selected via the input unit 20 from a display program. The display control unit 50 displays a window depicted by the read display program on the main display unit 11. In addition, the display control unit 50 stores data that is arranged in a selection sequence for identifying the windows currently displayed on the main display unit 11 as the last windows in the display content storage unit 40.

[0030] Furthermore, the display control unit 50 switches a window to be displayed on the main display unit 11 according to the input in the input unit 20 (the selection input unit 21). More precisely, the display control unit 50 reads a display program corresponding to a newly selected window via the input unit 20. The display control unit 50 performs such a switching operation that a window depicted by the read display program is displayed on the main display unit 11. The display control unit 50 displays windows previously displayed on the main display unit 11 on the sub-display unit 12. In the present example, the display control unit 50 shows, as in Fig. As shown, the display control unit 50 displays a window previously displayed on the main display unit 11 on the sub-display unit 12. This means that the display control unit 50 displays a window previously displayed on the main display unit 11 on the sub-display unit 12. More precisely, the display control unit 50 reads data arranged in the selection sequence stored in the display content memory unit 40 and reads a display program of the window previously displayed on the main display unit 11 from the display program memory unit 30. Using the read display program, the display control unit 50 displays a window on the sub-display unit 12. In the present example, the display control unit 50 displays, for instance, a window with window number 3 on the main display unit 11. Furthermore, the display control unit 50 displays a window previously displayed on the main display unit 11 with window number 2 on the sub-display unit 12.

[0031] Next, with reference to the flowchart according to Fig. Section 4 describes the workflow of the display device 1 of the injection molding machine 100 according to the present example. First, the input unit 20 (the selection input unit 21) receives an input from the operator M to select a window to be displayed on the main display unit 11 (step S1). Then, the display control unit 50 reads a display program corresponding to the selected window from the display program memory unit 30 and displays the selected window on the main display unit 11 (step S2). Furthermore, the display control unit 50 updates data by adding identification information to a window displayed on the main display unit 11, arranged in a selection sequence, as information about the newest window. The display control unit 50 stores the updated data in the display content memory unit 40.

[0032] The display control unit 50 then determines whether an input for selecting the next window is available via the input unit 20 (the selection input unit 21) (step S3). If the input for selecting the next window is available, the process continues with step S4. If the input for selecting the next window is not available, the display control unit 50 remains unchanged.

[0033] In step S4, the display control unit 50 reads a display program corresponding to the selected window from the display program memory unit 30. The display control unit 50 displays the window on the main display unit 11 using the read display program. The display control unit 50 reads data arranged in the selection sequence from the display content memory unit 40 and updates the data by adding information to identify the currently displayed window as the newest window. The display control unit 50 stores the updated data in the display content memory unit 40. Furthermore, the display control unit 50 reads a display program from the display program memory unit 30 based on the information about the newest window contained in the read data arranged in the selection sequence.The display control unit 50 displays a window on the sub-display unit 12, which is rendered using the read display program.

[0034] Subsequently, in step S5, the display control unit 50 determines whether an input for setting a parameter value is available via the input unit 20. If an input for setting the parameter value is available, the display control unit 50 terminates the process. If, on the other hand, no input for setting the parameter value is available, the process is reset to step S3.

[0035] The following advantages are achieved through the display device 1 of the injection molding machine 100. (B1) The display device 1 of the injection molding machine 100, which is suitable for displaying two or more windows, comprises the display unit 10, which has at least the main display unit 11 and the sub-display unit 12, the input unit 20, which receives the input relating to the selection of a window to be displayed on the display unit 10, and the display control unit 50, which selectively controls a window to be displayed on the display unit 10 according to the input into the input unit 20, wherein the display control unit 50 switches a window to be displayed on the main display unit 11 according to the input into the input unit 20 and displays a window previously displayed on the main display unit 11 on the sub-display unit 12.

[0036] In this way, if a selection is made to display a new window on the main display unit 11, the window previously displayed on the main display unit 11 is displayed on the sub-display unit 12. Since the operator can enter values ​​and the like into the main display unit 11 while referring to the sub-display unit 12, it is therefore possible to improve work efficiency during the pre-setting of the injection molding machine 100. Because the window previously displayed on the main display unit 11 is now displayed on the sub-display unit 12, it is particularly possible to display a window considered highly relevant for the main display unit 11 on the sub-display unit 12 and further improve work efficiency.

[0037] (B2) The display control unit 50 displays a window previously shown on the main display unit 11 on the sub-display unit 12. In this way, it is possible to automatically move the window already displayed on the main display unit 11 to the sub-display unit 12 and display the next window on the main display unit 11. Since the operator M can enter setting values ​​into the injection molding machine 100 while referring to a previous window, it is therefore possible to improve work efficiency. [Second example]

[0038] Next, with reference to the Fig. Sections 5 to 7 describe the display device 1 of the injection molding machine 100 according to a second example. In the description of the second example, the components corresponding to those of the example described above are designated by the same reference numerals, and their description is omitted or simplified. The display device 1 of the injection molding machine 100 according to the second example differs from that according to the first example in that the input unit 20 receives a switching input to toggle a window to be displayed on the sub-display unit 12. Furthermore, the display device 1 of the injection molding machine 100 according to the second example differs from that according to the first example in that the display control unit 50 switches a window displayed on the sub-display unit 12 to the input unit 20 according to the switching input.Furthermore, the workflow of the display device 1 of the injection molding machine 100 according to the second example differs from that according to the first example in that steps S21 and S22 are added between steps S4 and S5. Additionally, the workflow of the display device 1 of the injection molding machine 100 according to the second example differs from that according to the first example in that the process continues with step S23 if no input for setting the setpoint is present in step S5.

[0039] The input unit 20 can, for example, Fig. Figure 5 shows that the position detection device (as a touch-sensitive control panel) is configured in the sub-display unit 12 and in the main display unit 11. The input unit 20 is configured to receive input for switching a window to be displayed on the sub-display unit 12. More precisely, the input unit 20 comprises the selection input unit 21, which selects a window to be displayed on the main display unit 11, and a switching unit 22, which switches a window to be displayed on the sub-display unit 12.

[0040] Next, with reference to the flowchart according to Fig. Section 6 describes the workflow of the display device 1 of the injection molding machine 100 according to the present example. In step S21, the display control unit 50 determines whether a switching input is received to switch a window to be displayed on the sub-display unit 12. If the input is received, the process continues with step S22. If, on the other hand, no input is received, the process continues with step S5.

[0041] In step S22, following step S4, the display control unit 50 reads data arranged in a selection sequence from the display content storage unit 40. Based on the content entered into the input unit 20 (the switching unit 22), the display control unit 50 reads a display program relating to a window to be displayed on the sub-display unit 12 and displays a window on the sub-display unit 12. For example, if a display input for window tracking is received from the input unit 20 (the switching unit 22), the display control unit 50, referring to the data arranged in the selection sequence, performs a traceback to past data and displays a window previously displayed on the main display unit 11 on the sub-display unit 12.For example, if a display input for anticipating windows is received from input unit 20 (switching unit 22), the display control unit 50 also displays a window previously displayed on the main display unit 11 on the sub-display unit 12, based on the data arranged in the selection sequence. More precisely, if, for example, a display input for retrospectively tracking windows is received from input unit 20 (switching unit 22), the display control unit 50 displays a window (currently displayed on sub-display unit 12) on the sub-display unit 12 with respect to N operations previously displayed on the main display unit 11 (a window currently displayed on sub-display unit 12) (N + 1 operations previously displayed on the main display unit 11).

[0042] On the other hand, if, for example, a display input for anticipating windows is received from the input unit 20 (the switching unit 22), the display control unit 50 displays a window on the sub-display unit 12 that was displayed N operations earlier on the main display unit 11 (a window currently displayed on the sub-display unit 12) with respect to (N - 1) operations earlier. As, for example, in Fig. As shown in Figure 7, the display control unit 50 displays a window with window number 5 on the sub-display unit 12 when a window displayed three operations earlier on the main display unit 11 is selected using the input unit 20 (the switching unit 22). The process then continues with step S5.

[0043] Subsequently, in step S5, the display control unit 50 determines whether an input for setting a parameter value is available via the input unit 20. If an input for setting the parameter value is available, the display control unit 50 terminates the process. If, on the other hand, no input for setting the parameter value is available, the process is reset to step S23.

[0044] In step S23, the display control unit 50 determines whether an input for selecting a window to be subsequently displayed on the main display unit 11 is available via the input unit 20. If an input for selecting a window to be subsequently displayed on the main display unit 11 is available, the process continues with step S4. If no input for selecting the next window is available, the process continues with step S21.

[0045] The following advantages are achieved by the display device 1 of the injection molding machine 100. (B3) The input unit 20 receives a switching input to toggle a window to be displayed on the sub-display unit 12, and the display control unit 50 switches a window to be displayed on the sub-display unit 12 to the input unit 20 according to the switching input. In this way, the operator M can switch any window to be displayed on the sub-display unit 12. Since a suitable window can be displayed on the sub-display unit 12 without switching a window displayed on the main display unit 11, it is therefore possible to further improve work efficiency during the pre-setting of the injection molding machine 100. [First embodiment]

[0046] Next, with reference to the Fig. 8 and Fig. 9 The display device 1 of the injection molding machine 100 according to a first embodiment of the present invention is described. In the description of the first embodiment, the components corresponding to those of the examples described above are designated by the same reference numerals, and their description is omitted or simplified. As in Fig. As shown in Figure 8, the display device 1 of the injection molding machine 100 according to the first embodiment differs from that of the first and second examples in that the display device 1 further comprises a counting unit 60. Moreover, the display device 1 of the injection molding machine 100 according to the first embodiment differs from that of the first and second examples in that the display control unit 50 displays a window on the sub-display unit 12 where the number of repetitions of the display counted by the counting unit 60 is highest, instead of displaying a window previously displayed on the main display unit 11. As, for example, in Fig. As shown in Figure 9, the display control unit 50 displays a window with window number 3, where the number of repetitions of the display, which was shown on the main display unit 11, is highest, on the sub-display unit 12.

[0047] The counter unit 60 counts the number of repetitions of the display of a window shown on the main display unit 11. More precisely, the counter unit 60 counts the number of repetitions of the display of a window shown on the main display unit 11, for example, based on the data arranged in the selection order.

[0048] The following advantages are achieved by the display device 1 of the injection molding machine 100. (1) The display device 1 of the injection molding machine 100 further comprises the counter unit 60, which counts the number of repetitions of the display of a window shown on the main display unit 11, and the display control unit 50 displays a window for which the number of repetitions of the display counted by the counter unit 60 is highest on the sub-display unit 12. Since in this way a window for which the number of repetitions of the display on the main display unit 11 is highest is automatically displayed on the sub-display unit 12, it is possible to display a window whose frequency of use is considered to be high on the sub-display unit 12. This makes it possible to further improve work efficiency. [Second embodiment]

[0049] Next, the display device 1 of the injection molding machine 100 according to a second embodiment of the present invention is described. In the description of the second embodiment, the components corresponding to those of the examples described above and the first embodiment are designated by the same reference numerals, and their description is omitted or simplified. The display device 1 of the injection molding machine 100 according to the second embodiment differs from that of the first and second examples in that the display device 1 further comprises the counting unit 60.Moreover, the display device 1 of the injection molding machine 100 according to the second embodiment differs from that according to the first and second examples in that the display control unit 50 displays a window on the sub-display unit 12 where the number of repetitions of the selection is highest, following the window displayed on the main display unit 11, instead of displaying a window previously displayed on the main display unit 11 on the sub-display unit 12.

[0050] The counter unit 60 counts the number of repetitions of selecting a window for display on the main display unit 11. More precisely, the counter unit 60 counts, for example, the number of repetitions of selecting a window for display on the main display unit 11 after a window has already been displayed on the main display unit 11. The counter unit 60 reads data arranged in the selection sequence from the display content storage unit 40 and counts the number of windows selected after the window displayed on the main display unit 11 and the number of repetitions of their selection.

[0051] The following advantages are achieved by the display device 1 of the injection molding machine 100. (2) The display device 1 of the injection molding machine 100 further comprises the counting unit 60, which counts the number of repetitions of the selection of a window chosen for display on the main display unit 11 after a window displayed on the main display unit 11, and the display control unit 50 displays on the sub-display unit 12 a window for which the number of repetitions of the selection that the window was chosen for display on the main display unit 11 following the window displayed on the main display unit 11 is highest.Since, based on previous statistics, a window with the highest number of repetitions of its display on the main display unit 11 is first displayed on the sub-display unit 12, it is not necessary to select and display the next window on the main display unit 11. This makes it possible to further improve work efficiency. [Third embodiment]

[0052] Next, the display device 1 of the injection molding machine 100 according to a third embodiment of the present invention is described. In the description of the third embodiment, the components corresponding to those of the examples and embodiments described above are designated by the same reference numerals, and their description is omitted or simplified. The display device 1 of the injection molding machine 100 according to the third embodiment differs from that according to the first embodiment in that the display control unit 50 performs such control that a window can be displayed on the sub-display unit 12 when the number of repetitions counted by the counter unit 60 is equal to or greater than a predetermined number of repetitions.

[0053] The following advantages are achieved by the display device 1 of the injection molding machine 100. (3) The display control unit 50 performs such a control that a window, where the number of repetitions counted by the counter unit 60 is equal to or greater than a predetermined number of repetitions, can be displayed on the sub-display unit 12. In this way, if the number of repetitions of the window displayed on the main display unit 11 is less than the predetermined number of repetitions, it is possible to automatically prevent the window from being displayed on the sub-display unit 12. This makes it possible to suppress the display on the sub-display unit 12 of a window that is considered of little relevance to the main display unit 11, thus further improving work efficiency. [Fourth embodiment]

[0054] Next, the display device 1 of the injection molding machine 100 according to a fourth embodiment of the present invention is described. In the description of the fourth embodiment, the components corresponding to those of the examples and embodiments described above are designated by the same reference numerals, and their description is omitted or simplified.
