[0001] The present invention relates to a diagnostic device for an injection molding machine and an injection molding machine. [Background technology]

[0002] A diagnostic device for an injection molding machine according to the prior art is described, for example, in Patent Document 1. In the prior art, a function is provided that allows an operator to check the input and output signals and analog output signals of the injection molding machine using a diagnostic screen of a diagnostic unit (diagnostic device) incorporated in the control unit, and these are called diagnostic screens for diagnosing input and output. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-036325 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional technology, when performing maintenance and inspection of an injection molding machine, an operator could only check the address and ON / OFF status of the input signal to the control unit and the address and ON / OFF status of the output signal on the diagnostic screen, and had to separately check the electrical circuit diagram to see what each input signal and output signal corresponds to.

[0005] Furthermore, the prior art also has a function to forcibly output input signals, output signals, and analog output signals to a control screen. However, even in this case, it is not clear from the control screen what signals each corresponds to, so it is necessary to check the electrical circuit diagram. Therefore, with the prior art, the diagnostic work for the injection molding machine is complicated, and the operator cannot easily determine the operating status of the injection molding machine.

[0006] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a diagnostic device for an injection molding machine that allows an operator to easily determine the operating state of the injection molding machine. [Means for solving the problem]

[0007] The present invention provides a diagnostic device for an injection molding device, which is equipped with a display unit that can input an input signal for controlling the injection molding device and that displays a pop-up screen from which an output signal indicating the operating status of the injection molding device is output, The diagnostic device comprises: a plurality of input signal display units that display input signals to the injection molding device; a plurality of output signal display units that display output signals from the injection molding device; the input signal display unit includes an input switching button for switching the input signal ON / OFF, and a first information display area for displaying information indicating what kind of signal the input signal is for the injection molding device, the output signal display unit includes an output switching button for switching the output signal ON / OFF, and a second information display area for displaying information indicating what kind of signal the output signal is in the injection molding apparatus, This is a diagnostic device for an injection molding device, characterized in that when the input switching button or the output switching button is pressed, information indicating what kind of signal is associated with the input switching button or the output switching button and is directed to the injection molding device, or what kind of signal is associated with the injection molding device, is displayed in the first information display area or the second information display area.

[0008] In the invention, at least one of the input switching button and the output switching button further includes a forced output button for forcibly inverting the output of the input signal or the output signal.

[0009] In the invention, at least one of the input switching button and the output switching button further includes an execution switching button for switching ON / OFF of the forced output button.

[0010] The present invention also provides an injection molding machine comprising the above-described diagnostic device. [Effects of the Invention]

[0011] According to the present invention, the diagnostic device includes a plurality of input signal display units that display input signals to the injection molding apparatus main body, and a plurality of output signal display units that display output signals from the injection molding apparatus main body. The input signal display unit includes an input switch button that switches the input signal ON / OFF, and a first information display area that displays information indicating what kind of signal the input signal is for the injection molding apparatus main body. The output signal display unit includes an output switch button that switches the output signal ON / OFF, and a second information display area that displays information indicating what kind of signal the output signal is in the injection molding apparatus main body. When the input switch button or the output switch button is pressed, information indicating what kind of signal the output signal is for the injection molding apparatus main body or information indicating what kind of signal the output signal is in the injection molding apparatus main body, which is associated with the input switch button or the output switch button, is displayed in the first information display area or the second information display area.

[0012] Therefore, by touching an input switching button or an output switching button, the worker can check information about the signal linked to the touched input switching button or output switching button in the first information display area or the second information display area. This eliminates the need to separately compare the touched input switching button or output switching button with an electrical circuit diagram, allowing the worker to easily determine the operating status of the injection molding machine.

[0013] According to the present invention, the diagnostic device has a forced output button that forcibly reverses the output of an input signal or output signal in response to the input switching button or output switching button, so that the actual input signal or output signal can be virtually reversed to operate the injection molding device body. This makes it easy to change the operating status of the injection molding device, making it easy to diagnose various functions.

[0014] According to the present invention, the diagnostic device further includes an execution switch button for switching the forced output button between ON and OFF, thereby preventing the forced output button from being accidentally executed.

[0015] According to the present invention, the injection molding machine is provided with a diagnostic device, which allows an operator to easily determine the operating state of the injection molding machine. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] <Injection molding equipment> 1 is a side view of an injection molding apparatus 1 according to the present invention. The injection molding apparatus 1 includes a bed 2, an injection unit 3 disposed on the upper surface of the bed 2, and a mold clamping unit 4 disposed on the upper surface of the bed 2.

[0018] The injection device 3 has a nozzle 5 at its tip and is equipped with a heating barrel 7 incorporating a screw 6, a hopper 8 that supplies resin material to the inside of the heating barrel 7, and a rotation drive means 9 that rotates the screw 6 and moves it back and forth, and the resin material is injected from the nozzle 5 each time the screw 6 moves forward.

[0019] The mold clamping unit 4 is configured to include a fixed platen 10 fixed to the bed 2, a pressure platen 11, tie bars 12 arranged between the fixed platen 10 and the pressure platen 11, a movable platen 13 attached to the tie bars 12 so as to be movable in the longitudinal direction of the tie bars 12, a toggle link 14 stretched between the pressure platen 11 and the movable platen 13, and a toggle drive means 15 that drives the toggle link 14. The fixed platen 10 is fixed to the bed 2. The pressure platen 11 is arranged on the upper surface of the bed 2.

[0020] The tie bars 12 are made up of four rod-shaped bars, one pair of which is provided on the upper side and one pair of which is provided on the lower side, and are stretched between the fixed platen 10 and the pressure-receiving platen 11. A fixed mold 16 is attached to the fixed platen 10. A movable mold 17 is attached to the movable platen 13. The fixed mold 16 and the movable mold 17 form a mold 18. The mold 18 is clamped by pressing the movable mold 17 against the fixed mold 16 through the operation of the mold clamping device 4, and is opened by moving the movable mold 17 away from the fixed mold 16.

[0021] 1 is a block diagram showing the configuration of the injection molding apparatus 1. The injection molding apparatus 1 further includes a control unit 20 that controls the injection unit 3 and the mold clamping unit 4. The control unit 20 includes a CPU (Central Processing Unit) 21, a memory 22, and a display unit 23. The memory 22 stores various programs for executing the functions of the control unit 20. The control unit 20 has the function of controlling the injection molding apparatus 1. The display unit 23 is realized by a touch panel monitor consisting of a display main body and a touch panel, and displays input signals to and output signals from the injection molding apparatus. By operating the display unit 23, signals that control the operation of the injection molding apparatus 1 can be transmitted. The display unit 23 has the function of displaying the operating status of the injection molding apparatus 1.

[0022] <Diagnostic equipment> Diagnostic device 30 is realized by executing a program stored in memory 22 in control unit 20, and is displayed on display unit 23. Figure 3 is a diagram showing an example of a display screen shown on the display unit of diagnostic device 30.

[0023] The diagnostic device 30 has an input signal display area 31 displaying a plurality of input switching buttons 41 that display input signals to the injection molding device 1, an output signal display area 32 displaying a plurality of output switching buttons 42 that display output signals from the injection molding device 1, a mode switching button display area 33 displaying a plurality of mode switching buttons 43 that switch the mode of the control unit 20, and an analog diagnostic button 45 that switches the input and output signals to analog display.

[0024] The mode switching button 43 is a button for switching the mode of the diagnostic device 30, and is a button for executing a plurality of modes and display formats associated with the modes, such as a mode for displaying the amount of resin injected by the injection unit 3, the metering time, etc., and a mode for displaying the status of each device connected to the control unit 20. The analog diagnosis button 45 is a button for switching the input and output signals to analog display.

[0025] A plurality of input switching buttons 41 are arranged in a matrix within the input signal display area 31. Each input switching button 41 displays the ON / OFF state of an input signal linked to a device in the injection molding apparatus main body. Each input switching button 41 also functions as a switching button that switches the ON / OFF state of the linked input signal when pressed (touched) by the operator's finger.

[0026] 3, when the input switch button 41 is ON, it is displayed in a colored state as shown by a hatched pattern, and when it is OFF, it is displayed in a white state. Specifically, the input switch button 41 in row X10, column F is displayed in the OFF state, and the input switch button 41 in row X30, column F is displayed in the ON state.

[0027] A plurality of output switching buttons 42 are arranged in a matrix within the output signal display area 32. Each output switching button 42 displays the ON / OFF state of an output signal associated with a device in the injection molding apparatus main body. Each output switching button 42 also functions as a switching button that switches the associated output signal ON / OFF when pressed (touched) by the operator's finger.

[0028] 3, when the output switching button 42 is ON, it is colored as shown by a hatched pattern, and when it is OFF, it is displayed as a white outline. Specifically, the output switching button 42 in row Y10, column 0 is displayed in the OFF state, and the output switching button 42 in row Y40, column 1 is displayed in the ON state.

[0029] The input signal display area 31 and the output signal display area 32 are provided with scroll buttons 44 for scrolling up and down either the input signal display area 31 or the output signal display area 32. By using the scroll buttons 44, the operator can easily change the rows of the input switch buttons 41 and output switch buttons 42 displayed in the input signal display area 31 and the output signal display area 32.

[0030] <Normal mode> FIG. 4 is a diagram showing a case where the input switching button 41 is touched while the diagnostic device 30 is operating in normal mode. In this embodiment, when the operator touches the input switching button 41, a pop-up screen 50 is displayed. As shown in FIG. 4, the pop-up screen 50 displays the touched input switching button 41 and, above the input switching button 41, a first information display area 51 that displays information indicating what kind of signal the input signal associated with the input switching button 41 is for the injection molding device 1. In the example shown in FIG. 4, Y13 of the input switching button 41 displays "Controller Normal," indicating that the controller signal is being transmitted normally.

[0031] The display of the first information display area 51 is not limited to the example of Figure 4. For example, when an operator touches the input switching button 41 located at Y13, the pop-up screen 50 may not be displayed, and only the first information display area 51 may be displayed as a pop-up screen.

[0032] Similarly, when the output switching button 42 is touched, a pop-up screen 50 is displayed, similar to the case of the input switching button 41. The pop-up screen 50 displays the touched output switching button 42 and, above the output switching button 42, a second information display area 52 that displays information indicating what kind of signal in the injection molding apparatus 1 the output signal associated with the output switching button 42 is.

[0033] In this way, when the input switching button 41 and the output switching button 42 are touched, a pop-up screen 50 is displayed. The pop-up screen 50 displays the touched input switching button 41 or output switching button 42, as well as a first information display area 51 that displays information indicating what kind of signal the input signal associated with the input switching button 41 is for the injection molding apparatus 1, or a second information display area 52 that displays information indicating what kind of signal the output signal associated with the output switching button 42 is for the injection molding apparatus 1. Therefore, by touching the input switching button 41 or the output switching button 42, the operator can know the signal associated with the touched input switching button 41 or output switching button 42, and the operator can easily determine the operating state of the injection molding apparatus 1 using the diagnostic device 30.

[0034] <Special mode> FIG. 5 is a diagram showing a case where the input switching button 41 is touched while the diagnostic device 30 is operating in the special mode. In this embodiment, when the operator touches the input switching button 41, a pop-up screen 55 is displayed. As shown in FIG. 5, the pop-up screen 55 displays the touched input switching button 41 and, above the input switching button 41, a first information display area 51 that displays information indicating what kind of signal the input signal associated with the input switching button 41 is for the injection molding apparatus 1. In the example shown in FIG. 5, Y13 of the input switching button 41 displays "Controller Normal," indicating that the controller signal is being transmitted normally.

[0035] Furthermore, a forced output button 56 that forcibly inverts the output of the input signal and an execution switch button 57 that switches ON / OFF of the forced output button 56 are provided below the first information display area 51. In the example shown in Fig. 5, both the forced output button 56 and the execution switch button 57 are in the ON state.

[0036] The forced output button 56 forcibly inverts the output of the input signal. This makes it possible to virtually create a state in which a signal is being transmitted even when no signal is actually being transmitted, and vice versa. Therefore, since the input signal linked to the input switching button 41 can be virtually turned on / off, it is possible to easily diagnose whether the sensor monitoring the input signal is working properly.

[0037] The execution switching button 57 switches whether or not to execute the function of the forced output button 56. By operating the execution switching button 57, it is possible to prevent the forced output button 56 from being activated accidentally.

[0038] As a modification of this embodiment, when the forced output button 56 is ON, the background, outer frame, etc. of the pop-up screen 55 may be highlighted in red, etc. In this way, it is easy to visually confirm that the forced output button 56 is activated, and work errors can be reduced.

[0039] The forced output button 56 and the execution switching button 57 have been explained using the input switching button 41 as an example, but the forced output button 56 and the execution switching button 57 are also provided on the output switching button 42, and so a redundant explanation will be omitted.

[0040] <Screen display flowchart> Fig. 6 is a flowchart illustrating the screen transition of diagnostic device 30. When diagnostic device 30 is started, step S0 is reached, the screen shown in Fig. 3 is displayed, and the process proceeds to step S1.

[0041] In step S1, a touch operation by the operator is accepted. When the operator touches the desired input switching button 41, the process proceeds to step S2.

[0042] In step S2, diagnostic device 30 determines whether the currently executed mode is the normal mode or the special mode. If the currently executed mode is the normal mode, the process proceeds to step S3, and if the currently executed mode is the special mode, the process proceeds to step S10.

[0043] In step S3, diagnostic device 30 displays a normal mode screen on display unit 23 (see FIG. 4), and then proceeds to step S4.

[0044] In step S4, diagnostic device 30 displays the raw values ​​output from control unit 20 or the raw values ​​output from the molding device main body as input switch button 41 or output switch button 42, and then proceeds to step S5.

[0045] In step S5, the raw values ​​obtained in step S4 are used to control the molding device main body.

[0046] In step S10, diagnostic device 30 displays a special mode screen on display unit 23 (see FIG. 5), and then proceeds to step S11.

[0047] In step S11, the diagnostic device 30 determines whether the forced output button 56 is ON. If the forced output button 56 is ON, the process proceeds to step S12. If the forced output button 56 is OFF, the process proceeds to step S4.

[0048] In step S12, diagnostic device 30 determines whether execution switching button 57 is ON. If execution switching button 57 is ON, the process proceeds to step S13. If execution switching button 57 is OFF, the process proceeds to step S4.

[0049] In step S13, the diagnostic device 30 executes the function of the forced output button 56. At this time, if the forced output button 56 is ON, the diagnostic device 30 executes the function of the forced output button 56, forcibly inverts the output of the input signal or output signal, and proceeds to step S5.

[0050] <Analog display> Fig. 7 is a diagram showing an example of a display when the analog diagnosis button 45 is pressed. When the analog diagnosis button 45 is pressed, the analog diagnosis mode is executed. In the analog diagnosis mode, the display format of the input signal display unit 31 and the output signal display unit 41 is changed to an analog display, and the analog data detected by each sensor is displayed. This allows the operator to easily know the analog data of the desired location.

[0051] According to this embodiment, the diagnostic device 30 includes a plurality of input signal display units 31 that display input signals to the injection molding apparatus main body, and a plurality of output signal display units 32 that display output signals from the injection molding apparatus main body. The input signal display unit 31 includes an input switching button 41 that switches the input signal ON / OFF, and a first information display area 51 that displays information indicating what kind of signal the input signal is for the injection molding apparatus main body. The output signal display unit 32 includes an output switching button 42 that switches the output signal ON / OFF, and a second information display area 52 that displays information indicating what kind of signal the output signal is for the injection molding apparatus main body. When the input switching button 41 or the output switching button 42 is pressed, information indicating what kind of signal the output signal is for the injection molding apparatus main body or information indicating what kind of signal the output signal is for the injection molding apparatus main body, which is associated with the input switching button 41 or the output switching button 42, is displayed in the first information display area 51 or the second information display area 52.

[0052] Therefore, by touching the input switching button 41 or the output switching button 42, the worker can check information about the signal linked to the touched input switching button 41 or output switching button 42 in the first information display area 51 or the second information display area 52. This eliminates the need to separately compare the touched input switching button 41 or output switching button 42 with an electrical circuit diagram, allowing the worker to easily determine the operating state of the injection molding apparatus 1.

[0053] Furthermore, according to this embodiment, diagnostic device 30 has forced output button 56 that forcibly reverses the output of an input signal or output signal in response to input switch button 41 or output switch button 42, so that the injection molding apparatus main body can be operated by virtually reversing the actual input signal or output signal. This makes it possible to easily change the operating status of injection molding apparatus 1, and therefore to easily diagnose various functions.

[0054] Furthermore, according to this embodiment, diagnostic device 30 further includes an execution switch button 57 that switches ON / OFF of forced output button 56. This makes it possible to prevent forced output button 56 from being accidentally pressed.

[0055] Furthermore, according to this embodiment, the injection molding apparatus 1 is provided with a diagnostic device 30. This allows an operator to easily determine the operating state of the injection molding apparatus 1.

[0056] Although the embodiments of the present invention have been described in detail above, for example, the input and output signals may be in analog notation or may include analog signals. Furthermore, the present invention is not limited to the above-described embodiments, and various modifications and improvements are possible within the scope of the gist of the present invention. It goes without saying that all or part of the components constituting each of the above-described embodiments can be combined as appropriate within the scope of not contradicting each other.
