This is software for realizing display of operation monitoring data of the molding machine M and the like. These softwares are constructed as a unique architecture of the injection molding machine M equipped with the controller 20, and particularly realize the abnormality clearing device 1 according to the present embodiment, that is, when a relatively heavy abnormality (heavy abnormality) occurs. A window display function for displaying on the display 2 an abnormality display window We (FIG. 1) having an abnormality display column Ce displaying the content of the abnormality and an abnormality release button Kr using the touch panel 3 adjacent to the abnormality display column Ce; Further, it is possible to realize a light abnormality display function of displaying the contents of an abnormality (light abnormality) other than the heavy abnormality on a predetermined display unit 6 (FIG. 1) of the display 2. 33 indicates a power supply and 34 indicates a power switch.
[0016]
Next, a processing method at the time of occurrence of an abnormality including the function of the abnormality canceling device 1 according to the present embodiment will be described with reference to FIGS.
[0017]
Now, it is assumed that the injection molding machine M is operating and a predetermined molding process is being performed in the automatic mode. Then, it is assumed that an abnormality occurs during the molding (step S1).
[0018]
In this case, when the generated abnormality is a minor abnormality, the minor abnormality display function provided in the controller 20 displays an abnormality code indicating the content of the minor abnormality on the display unit 6 (FIG. 1) provided at the upper part of the screen of the display 2. The displayed abnormal message is displayed (steps S2 and S3). As for the minor abnormality, it is sufficient to remove the minor abnormality according to the abnormality message, and basically does not affect the operation of the molding process.
[0019]
On the other hand, when the occurred abnormality is a serious abnormality, the abnormality display window We as shown in FIG. 1 is displayed on the display 2 by the window display function provided in the controller 20 (steps S2 and S4). In addition, the process monitoring screen Va is displayed on the display 2 as shown in FIG. The outline of the process monitoring screen Va will be described. A plurality of screen switching keys K1, K2, K3... Provided for each screen item for switching various screens Va... Are displayed in the upper and lower stages of the process monitoring screen Va. The screen switching keys K1... Are ranked in consideration of the frequency of use. In the upper row, a mold opening / closing screen switching key K1, an ejector screen switching key K2, an injection / metering screen switching key K3, and a temperature screen switching key K4. , Monitor screen switching key K5, main condition screen switching key K6, condition switching screen switching key K7. A second group Gb having a setup screen switching key K8, a process monitoring screen switching key K9, a production information screen switching key K10, a waveform screen switching key K11, a statistics screen switching key K12, and a trend screen switching key K13 is arranged in a horizontal line. I do.
[0020]
The screen switching keys K1 are displayed in the same manner even when the process monitoring screen Va is switched to another screen, that is, displayed in the same position and in the same shape. Note that the second group Gb displayed in FIG. 1 is in a state where the first hierarchy is displayed, but by touching a hierarchy screen switching key Kc at the right end of the screen, a history screen switching key in the second hierarchy is displayed. The program screen switching key, the signal recorder screen switching key, the diagnostic screen switching key, and the like are displayed in the same manner as the screen switching keys K8 to K13. In addition, the controller 20 has an array change function that can arbitrarily change the array of the screen switching keys K1... On the user side and an array storage function that stores the changed array. Thereby, the user himself / herself can arbitrarily change the arrangement (order) of the screen switching keys K1. By such a layout display, even when the name display displayed on each of the screen switching keys K1... Is changed, it is possible to easily cope with the software, thereby reducing the man-hours and costs associated with the change, and at the same time, changing each screen switching key K1. … Can be improved in visibility and operability.
[0021]
Then, an error display window We is displayed (window display) almost at the center of the process monitoring screen Va. Since the abnormal display window We has the title bar 7 at the upper end, the user can touch the title bar 7 to arbitrarily change the display position to an easily-viewable display position or a display position that draws attention. The display position is stored. Therefore, thereafter, the abnormal display window We is displayed at the stored display position. Further, the abnormal display window We displays the other windows with the highest priority. Therefore, even when another window is displayed on the process monitoring screen Va, the abnormality display window We is displayed on the foreground.
[0022]
The abnormality display window We has both an abnormality display column Ce displaying the content of the abnormality and an abnormality release button Kr adjacent to the abnormality display column Ce and using the touch panel 3. The abnormality release button Kr is displayed with a color that draws attention such as yellow, for example, and is displayed at the upper right of the abnormality display window We. On the other hand, in the abnormality display column Ce, one or more strip-shaped abnormality display portions 5a... For displaying one abnormality are displayed. One error display section 5a displays an error code 5ac (for example, "3900d") and an error message 5am (for example, "the injection most forward position has been exceeded."). Such a display format is the same in the other abnormality display sections 5b, 5c.
[0023]
Further, the abnormality display window We sequentially displays all the abnormalities (5a,...) That have occurred. FIG. 1 shows an example in which three abnormalities that have occurred, that is, three abnormal display sections 5a, 5b, and 5c are displayed in order from the top. Although the number of the abnormal display portions 5a is usually one in many cases, the number to be displayed is not limited. Therefore, four or more abnormality display sections 5a may be displayed. Therefore, by such an abnormality display window We, the abnormality release button Kr is arranged adjacent to the abnormality display column Ce displaying the contents of the abnormality, and the integrity between the two is ensured.
[0024]
On the other hand, the operator confirms the abnormality display window We and performs a processing operation for removing the abnormality (step S5). For example, in the case of the embodiment, since the content of the abnormality displayed on the abnormality display section 5a is over the injection most advanced position, the process of removing the abnormality includes switching the operation mode of the injection molding machine M to the manual mode, Since there is a high possibility that a defective product has been molded, a process of removing the molded product is performed. In this case, resetting to the abnormality occurrence signal is performed by switching to the manual mode once. Therefore, if the abnormality release button Kr is touched thereafter, the abnormality removal processing for the abnormality displayed on the abnormality display section 5a has already been completed, and the display on the abnormality display section 5a disappears (steps S6 and S7). Further, predetermined abnormality removal processing corresponding to the abnormality displayed on the abnormality display sections 5b and 5c is also performed (steps S8, S5 to S7). Then, the abnormality removal processing for the abnormality displayed on the last abnormality display section 5c is completed, and if the abnormality release button Kr is touched, the abnormality display window We is closed, and the injection molding machine M returns to the state before the occurrence of the abnormality. The process returns (step S9).
[0025]
As described above, the abnormality clearing device 1 according to the present embodiment uses the window display function of the controller 20 to display the abnormality display window Ce having the abnormality display column Ce and the abnormality release button Kr adjacent to the abnormality display column Ce on the display. 2, the integrity of the abnormality display section Ce (the abnormality display section 5a ...) and the abnormality release button Kr is secured, and a series of abnormalities in which the abnormality release button Kr is operated while confirming the details of the abnormality. The release operation can be performed smoothly, and the convenience can be improved. Further, since the abnormality release button Kr can be eliminated from the side panel 13, the overall operability can be improved by simplifying the operation part. In addition, the contents of the minor abnormality are displayed on the predetermined display unit 6 of the display 2 by the minor abnormality display function, so that the operator can easily and quickly recognize (identify) whether the abnormality is a major abnormality or a minor abnormality. it can.
[0026]
Although the embodiment has been described in detail above, the present invention is not limited to such an embodiment, and the configuration, arrangement, number, method, etc. of the details can be arbitrarily set without departing from the gist of the present invention. Can be changed, added, or deleted. For example, in the abnormality display window We, the case where the abnormality display section Ce and the abnormality release button Kr are displayed is shown, but the case where other information or the like is displayed, such as displaying the explanation of the abnormality release method together, is excluded. Not something.
[0027]
