  Further, since the graph display unit Ew is provided as a part of the signal recorder screen Vs, FIG. 1 shows a mode in which the channel setting screen Vsc and the detailed setting screen Vss are displayed in windows below the graph display unit Ew. ing. The graph display unit Ew can display a change waveform W1 ... of one or more signals Sm ... selected from the signals Sm ... described above, and examples are set to CH1 (1 channel) to CH6 (6 channels). A mode in which the six signals Sm. The graph display unit Ew sets time on the horizontal axis 40t, and sets the magnitude of the signal Sm... On the vertical axis 40v according to the display magnification and the display 0 position.

  For this reason, the horizontal axis setting unit 41 and the vertical axis setting unit 42 are displayed at the upper position of the signal recorder screen Vs, and the channel display width setting units 43 of the respective CH1 to CH6 are provided at the horizontal position. As a result, six types of signals Sm... Set in CH1 to CH6 are displayed on the graph display section Ew by the change waveforms W1, W2, W3, W4, W5, and W6. In this case, the display portions of CH1 to CH6 in the channel display width setting unit 43 are color-coded, and the colors of CH1 to CH6 and the colors of the respective change waveforms W1.

The detailed setting screen Vss shown in FIG. 3A is made easier to see by changing the overall shape of the detailed setting screen Vss shown in FIG. On this detailed setting screen Vss, the trigger condition is set, that is, the trigger type is set by the trigger type setting unit 66, the trigger channel is set by the trigger channel setting unit 67, and the trigger is set by the trigger level setting unit 68. Levels can be set.

  A specific example when the trigger condition is set is as follows. Assume that the trigger condition is set according to the signal size. As an example, if the trigger condition is set to the level Lu [%] on the vertical axis, only the portion exceeding the set level Lu is displayed and the others are not displayed. Similarly, only the portion that does not reach the level Lu can be displayed, and these can be arbitrarily selected. Further, by setting a level Ld smaller than this level Lu in addition to the level Lu, it is also possible to display only the change waveform W1...

Note that the start time and the end time do not necessarily mean time, and arbitrary trigger conditions can be set depending on the time or section, for example, the timing of process start or the like. Furthermore, if the pre-trigger timing described above is set, the change waveform can be displayed (recorded) for a certain time before or a certain amount before the trigger condition, and the state immediately before the trigger condition can be confirmed. Can do.

In addition, the process display part Ep shown in FIG. 2 is made easy to see by drawing a wide vertical width with respect to the process display part Ep shown in FIG. If such a process display part Ep is provided, even if it is difficult to grasp the operation time point of the change waveform W1... In the first graphic display area Aw, the process display part whose timing coincides with the change waveform W1. Ep has an advantage that the operation time point (operation process (Pi...)) Can be easily grasped from a visual viewpoint.

  The process display unit Ep illustrated in FIG. 2 includes six region parts B... From the left side, an ejector process Pe, a mold clamping process Pc, an injection process Pi, a cooling process Pr / a metering process Pm, and a mold opening process Po. Show. In this way, as long as at least the injection process Pi, the metering process Pm, the cooling process Pr, the mold opening process Po, the ejector process Pe, and the mold clamping process Pc are included as the types of operation processes (Pi ...) to be displayed, Since the basic operation process (Pi...) In the injection molding machine M can be covered, it is optimal as the display device 1 for the injection molding machine. In the case of the example, since the measuring process Pm and the cooling process Pr partially progress at the same time, the simultaneous progress area is displayed in two layers (multilayered) by setting the vertical width to ½ width respectively. . Thus, when displaying the process display unit Ep, if the types of a plurality of operation processes (Prm...) That proceed at the same time are displayed in multiple layers, the overall shape and size of the process display unit Ep are not changed. The target display can be performed easily and reliably, and even a plurality of operation steps (Prm...) Can be easily grasped.

  In addition, each region portion B is color-coded according to the color scheme indicating the type for each type of operation step (Pi...). If such color coding is performed, there is an advantage that an operator or the like can intuitively and quickly grasp the type of the operation process (Pi...). In this case, the color scheme can be set using the detailed setting screen Vss displayed on the window by turning on the above-described detailed setting key 47 on the signal recorder screen Vs shown in FIG. First, when the process color setting key 60 on the detailed setting screen Vss shown in FIG. 3A is turned on, the process color setting screen Vc shown in FIG. 3B is displayed in a window. Then, if an arbitrary process display field Cp corresponding to the type of each operation process (Pi...) Displayed on the process color setting screen Vc is selected (touched), a color list screen that saves illustration is displayed in a window. Therefore, an arbitrary color can be set by selecting (touching) a desired color. The color arrangement may be a preset color (common color) set in the molding machine control 2, and the process color setting screen Vc may function as a process color confirmation screen.

  On the other hand, the display device 1 includes at least a display processing unit 4 that performs data processing for simultaneously displaying the change waveform W1 of the operation physical quantity and the type of the operation process (Pi ...) on the graphic display unit A. The display processing unit 4 is configured by using the data processing function of the molding machine controller 2, and in particular, the type of each operation process (Pi ...), that is, the injection process Pi, the metering process Pm, the cooling process Pr, the mold opening. An automatic process display function for discriminating the process Po, the ejector process Pe, and the mold clamping process Pc based on the set molding condition data and displaying the type of each operation process (Pi ...) based on the result of the discrimination process Fa is provided. If such an automatic process display function Fa is provided, the start position and the end position of each operation process (Pi...) Displayed in the second graphic display area Ap are automatically set even when the molding conditions are changed. Since matching can be performed, there is an advantage that it is possible to eliminate the troublesomeness for an operator and the like and to improve convenience and to prevent human error.

  The above configuration is the main configuration of the display device 1 according to the present embodiment. Therefore, according to the display device 1 according to the present embodiment as described above, as a basic configuration, time or position is set on the horizontal axis on the display screen V of the display 3, and the size related to the operation physical quantity is set on the vertical axis. By setting, the first graphic display area Aw for graphically displaying the change waveform W1, W2, W3...

Can be quickly and accurately determined even by a beginner (non-skilled person), and can be easily determined even by a professional engineer other than the molding condition setter. Therefore, efficient and accurate troubleshooting, etc. should be performed even when a specialist engineer other than the operator performs troubleshooting on the data of only a part relating to the change waveform W1. Can do.

  By the way, although the signal recorder screen Vs can function as a substantial measuring instrument, if there is no knowledge or experience like a beginner or the like, the signal recorder screen Vs remains in the function of displaying the signal Sm related to the operation. It is not easy to accurately diagnose and deal with trouble by looking at the change waveform of the signal Sm. Therefore, when such diagnosis, analysis, and countermeasures cannot be performed by themselves, data can usually be transmitted to the technical center for assistance. The display device 1 according to the present embodiment also functions effectively in this case.

  That is, in this case, the operator transmits information related to the trouble (trouble information) to the technical center. Since the technical center has at least a function for diagnosing trouble, when trouble information is received from the user, the processing computer (server) 91 creates processing of collecting condition data Di corresponding to the trouble information and transmits it to the user (reply) ) This collection condition data Di is data in which conditions for collecting operation signal data corresponding to trouble information are set by the molding machine controller 2 of the injection molding machine M. Specifically, the trouble on the signal recorder screen Vs is set. This is data for collecting screen areas related to information.

  Therefore, it is desirable that the collection condition data Di include at least one or more of the types, display ranges (display magnification / display 0 position), and trigger conditions for starting collection of the signal Sm. The display range (display magnification / display 0 position) serves as setting information for the vertical axis in the graph display section Ew. Furthermore, the trigger condition for starting the collection is so-called setting information on the horizontal axis. Various settings can be made with such collection condition data Di, and in particular, the various conditions described above can be set as the trigger condition. As described above, if at least one of the type, display range (display magnification / display 0 position), and trigger condition for starting the collection of the signal Sm... Furthermore, the minimum information for quickly grasping the degree and behavior of the abnormality can be easily secured.

  Further, when creating the collection condition data Di, the signal recorder screen Vs displayed on the display 3 can be collected and created by hard copy. That is, since the collection of the operation signal data based on the collection condition data Di is the collection of the signal recorder screen Vs, it can be collected by hard copy as it is according to the conditions created for the signal recorder screen Vs. If collected in this way, a technician in the technical center can deal with the situation almost in the same manner as when viewing the display 3 of the actual injection molding machine M. On the other hand, the collection condition data Di is created as a data file. If the collection condition data Di is created as such a data file, it can be handled as easily and universally as a general data file, so that a technician in the technical center reads it into the processing computer 91 as it is. In addition, it is possible to improve the usability of the collection condition data Di by using a simulator function or the like, enabling easy and detailed diagnosis and analysis, and enabling quick and accurate diagnosis and analysis. . This data file (collection condition data Di) can also be displayed (redisplayed) on the display 3 provided in the injection molding machine M. If such display (re-display) is made possible, for example, a user or a professional engineer who is present at the site checks the waveform data of the data file displayed on the display 3 and performs necessary troubleshooting for the actual machine. be able to.

  On the other hand, when the user receives the collection condition data Di, the collection condition data Di is read into the molding machine controller 2 and processed. In this case, as described above, since it is possible to take in directly via the communication interface 35 or via the storage medium 28, when it becomes possible to take in, a file display screen for setting molding conditions and the like is displayed, and the file name is displayed. Is input as a data file. As a result, the collection condition data Di is taken into the internal memory 25 of the molding machine controller 2 as a data file with a file name. Therefore, it can be easily used in the same manner as various condition files such as molding condition files and program files used in normal production activities.

  Next, the collection condition data Di file is opened and the collection process is executed. That is, a part of the signal recorder screen Vs is hard copied, and a data file of hard copied data (copy data) is created. In this case, both graphic data displayed in the first graphic display area Aw and the second graphic display area Ap are collected together by the collection condition data Di. Therefore, the display processing unit 4 has a data collection function Fd that can collect both graphic data displayed in the first graphic display area Aw and the second graphic display area Ap together with predetermined collection condition data Di. Become.

  The created data file is sent to the Technical Center. In the technical center, based on the received operation signal data (copy data), a specialist engineer diagnoses and analyzes the trouble and creates technical information including information on necessary countermeasures as a data file. Thereafter, the created data file (technical information) is transmitted to the user. Thereby, the operator can take a necessary measure based on the received technical information, that is, a necessary measure (measure) for solving the trouble.

  If such troubleshooting is performed, the operation signal data of the signal recorder screen Vs displayed on the display 3 provided in the molding machine controller 2 of the injection molding machine M used by the user is sent to the technical center as it is. Diagnosis and analysis by technical center specialists is possible, so even if the operator on the user side has no knowledge or experience, such as a beginner, it can deal with problems accurately. The troubleshooting tool on the signal recorder screen Vs can be used effectively. In addition, even if the operator is unfamiliar with the operation of the molding machine controller 2 of the injection molding machine M or is a foreigner who is incapable of language, etc., it should respond accurately and smoothly (quickly) to troubles. Can do.

  Further, the data collection function Fd described above allows the technical center side to enjoy the functions and effects of the display device 1 as they are. That is, it is possible to effectively eliminate the difficulty of determining the operation time point when confirming the display screen of the displayed operation signal data. As a result, it is possible to easily and surely determine the operation point at which the magnitude or change of the change waveform W1 that appears to be abnormal occurs, especially when a specialist other than the operator performs troubleshooting. Understand and perform efficient and accurate troubleshooting.
