Description

  The present invention relates to a molding machine such as an injection molding machine or a die-casting machine, and more particularly to a molding machine provided with an indicator lamp that notifies the occurrence of an alarm.

  In a molding machine such as an injection molding machine, the system controller of the machine (molding machine) performs self-diagnosis of the machine status, and if there is an abnormality or misoperation / insufficient operation, it is displayed on the machine display device. , An alarm message representing the outline of the contents of the alarm is automatically displayed. Furthermore, even in a manufacturing site where multiple machines are operating, in order to ensure that the operator (machine operator) knows which machine the alarm has occurred, an alarm message is displayed. At the same time, there is a model in which an indicator lamp that indicates that an alarm has occurred in the machine protrudes above the machine so that it can be easily seen from some distance.

  And in the machine equipped with such indicator lights, there are two types of alarm display modes using indicator lights: red indicator lights and blinking red indicator lights at regular intervals. Prepared by the manufacturer, the user side of the machine selects and sets the display mode of the alarm by the indicator light either by turning on the red indicator light or by flashing the red indicator light at regular intervals. It was like that.

  Assuming that the machine has a configuration as described above, even a worker who manages multiple machines can easily identify which machine caused the alarm, Even if there is an operator away from the machine, it can be remotely recognized that an alarm has occurred on the machine.

  However, the alarm display mode using the indicator lamp is only one pattern that the user can select from two patterns (lighted or blinking at regular intervals) prepared by the manufacturer. Whether it is a thing or a severe thing, it has become a uniform display form. For this reason, there has been a desire to be able to determine the alarm level by displaying the indicator light.

  The present invention has been made in view of the above points, and an object of the present invention is to enable an alarm level to be identified by the type of display mode of an indicator lamp in a molding machine having an indicator lamp that notifies the occurrence of an alarm. There is to do.

  In order to achieve the above-described object, the present invention provides a molding machine equipped with an indicator lamp that notifies the occurrence of an alarm so that the user can set a plurality of alarm display modes according to the type of alarm. Composed.

  According to the present invention, since the user can set the alarm display mode by the indicator lamp according to the alarm type (level), the remote display mode of the indicator lamp (difference in display pattern) It is possible to determine the level of an alarm generated in the machine. In addition, since the user can arbitrarily set the display mode of the indicator lamp, the display mode can be set according to the user's preference, and the concept of dealing with different alarm levels for each user coming from a production management request, etc. Correspondingly, the display mode type can be set with different levels for each user.

The monitor calculation processing unit 108 performs an operation condition setting storage unit rewritably storing the operation conditions for each process of injection molding, and 109 stores various history data such as periodic inspection history and alarm history. The history storage unit 110 is a fixed data storage unit for display that stores data such as text, graphics, and ruled lines necessary for an image to be displayed.

  The input device 6 is provided with an image call key for each mode type for calling up images in various modes. The operator (operator) pushes a desired image call key so that the display processing unit 101 can designate the image call key. The generated image is generated and displayed on the display screen of the display device 7. That is, in response to the operator's push operation of the image call key, the display processing unit 101 reads data as necessary from the above-described units 106, 107, 108, 109, 110, etc., and generates a pre-created image. Various images are generated according to the program and displayed on the display screen of the display device 7.

  In addition, when the state determination unit 109 that monitors the state of the injection molding machine or peripheral device determines that an event that requires the output of an alarm message has occurred, the state determination unit 109 responds accordingly. The alarm message data to be transferred is transferred from the message storage unit 105 to the display processing unit 101, and the display processing unit 101 is instructed to generate a window image using the alarm message data and output the window image. . In response to this, the display processing unit 101 uses the data stored in the message storage unit 105 and the fixed display data storage unit 110 according to the alarm window image generation program created in advance to generate a window image for the alarm message. It is generated and automatically interrupted and displayed on the display screen of the display device 7. At the same time, the state determination unit 104 instructs the display mode setting storage / indicator control unit 102 to output a signal corresponding to the alarm level and perform an alarm display by the indicator lamp 4, and receives this. The display mode setting storage / indicator control unit 102 selects a display mode corresponding to the instructed alarm level from a plurality of display modes (display patterns) set in advance according to each alarm level, and selects this display mode. A control signal is output to the on / off control unit 8 so that the indicator lamp 4 displays an alarm in the selected display mode, and the on / off control unit 8 switches on / off of the display lamp 4 according to the control signal.

The alarm sound output unit 4 outputs an alarm sound by, for example, a piezoelectric buzzer according to this control signal.

  In the present embodiment, an operator (operator) is in a state of displaying an image in an image group belonging to a certain mode type (in this case, for example, a state in which an image in a maintenance mode is displayed). When an operation of pushing a predetermined function key shown in the display image on the display device 7 (an operation using the input unit 7a of the display device 7) is performed, the display processing unit 101 uses the indicator lamp 4 according to the alarm level. A window image for setting the display mode for setting the display mode of the alarm display is generated and displayed. That is, when an operator pushes a predetermined function key to instruct to call a window image for display mode setting, the display processing unit 101 follows a window image generation program for display mode setting created in advance. Using the data in the display mode setting storage / indicator control unit 102 and the fixed display data storage unit 110, a window image for display mode setting as described later is generated, and this is interrupted on the display screen of the display device 7 Display. Then, using this display mode setting window image, the operator (operator) can set and change the display mode of the alarm display by the indicator lamp 4 as will be described later. The window image calling condition and the calling operation for setting the display mode are not limited to the above and are arbitrary.

  Next, the operation of setting / changing the display mode of the alarm display by the indicator lamp 4 in the present embodiment will be described. When the image call key for maintenance mode among the image call keys for each mode type provided in the input device 6 is pushed, for example, a periodic check table and a grease greasing check table as shown in FIG. 3 are displayed. The inspection image 21 is displayed on the display screen of the display device 7. Below the inspection image 21, function keys 22 are displayed. These function keys 22 are used for switching the image in the maintenance mode, calling up the calculator function, etc. One of these function keys is displayed. The function key 22-AS for calling a window image for setting the display mode of the indicator lamp 4 is provided. Then, by pushing this function key 22-AS, a window image 23 for setting the display mode corresponding to the alarm level is displayed as shown in FIG. In this embodiment, a plurality of window images 23 corresponding to the alarm level can be sequentially switched and displayed as the display mode setting window image 23. For example, the alarm levels of levels A, B, C, and D can be displayed. Assuming that level A is the most severe alarm level in four stages and is a light alarm level in the order of level B → C → D, pressing function key 22-AS first corresponds to alarm level A. A window image 23 for setting the display mode is displayed. Then, when the “forward switching” mark 24 in the window image 23 for setting the display mode of the alarm level A is pushed, the window image 23 for setting the display mode of the alarm level B is displayed, and for setting the display mode of the alarm level B When the “advance switching” mark 24 in the window image 23 is pushed, the window image 23 for setting the display mode of the alarm level C is displayed, and “forward switching” in the window image 23 for setting the display mode of the alarm level C is displayed. When the mark 24 is pushed, a window image 23 for setting the display mode of the alarm level D is displayed. When the “return switch” mark 25 in the window image for setting the display mode of the alarm level D is pushed, the window image 23 for setting the display mode of the alarm level C is displayed, which is used for setting the display mode of the alarm level C. When the “return switching” mark 25 in the window image is pushed, a window image 23 for setting the alarm level B display mode is displayed, and the “return switching” mark 25 in the window image for setting the alarm level B display mode is displayed. When pushed, a window image 23 for setting the display mode of the alarm level A is displayed.

  4A shows a window image 23 for setting the display mode of the indicator lamp 4 (for example, the window image 23 for setting the display mode of the alarm level D), and the display corresponding to each alarm level. In the window image 23 for mode setting, an on / off setting frame 26 for setting on / off of the indicator lamp 4 is 16 for a predetermined second period (for example, a period of 3 to 10 seconds). In this way, various display modes (display patterns) that are repeated at a predetermined second cycle can be set. When the location of each on / off setting frame 26 is pushed with a finger or the like, the “re” mark is alternately displayed and erased, and the portion where the “re” mark is displayed becomes the portion where the indicator lamp 4 is lit. ing. In the setting state in the window image 23 for setting the display mode of the alarm level D shown in FIG. 4A, all the on / off setting frames 26 are set to “re” marks. Then, as shown to (b) of FIG. 4, the indicator lamp 4 becomes a display pattern which lights continuously.

  FIG. 5A shows an example of the setting state in the window image 23 for setting the display mode of the alarm level C. In such a setting state, as shown in FIG. The indicator lamp 4 blinks with a relatively long cycle. 6A shows an example of the setting state in the window image 23 for setting the display mode of the alarm level B. In such a setting state, as shown in FIG. 6B, The indicator lamp 4 blinks at a cycle shorter than that in FIG. FIG. 7A shows an example of the setting state in the window image 23 for setting the display mode of the alarm level A. In such a setting state, as shown in FIG. The indicator lamp 4 blinks at a cycle shorter than that shown in FIG.

  As shown in FIGS. 4 to 7, the alarm level A has a short blinking interval, the alarm level B has a moderate blinking interval, the alarm level C has a long blinking interval, and the alarm level D is continuously lit. The operator can easily determine the alarm level by the difference in the display mode (display pattern) of the indicator lamp 4. In addition, since the blinking interval of the indicator lamp 4 is considered to be more noticeable as it is shorter in the visible range, the more severe the alarm level, the more noticeable to the operator.

  It should be noted that the examples shown in FIGS. 4 to 7 are merely examples, and the display mode (display pattern) of the indicator lamp 4 can be set arbitrarily. For example, lighting at a predetermined time and blinking at an arbitrary period are combined. Or, a combination of a long blinking interval and a short blinking interval may be used.

  In addition, according to the way of dealing with different alarm levels for each user coming from a production management request or the like, the display mode type may be set for different levels for each user. That is, for example, the alarm level B to the alarm level D may all be continuously lit continuously, only the alarm level A may be blinked, and only the trouble event of the alarm level A may be immediately processed. .

  As described above, in the present embodiment, the display mode of the alarm by the display lamp 4 can be set by the user according to the type of alarm using the display mode setting window image 23. Therefore, the display lamp 4 Due to the difference in display mode, it is possible to determine the level of an alarm generated in the machine even from a remote location. In addition, since the display mode of the indicator lamp 4 can be arbitrarily set by the user, the display mode can be set according to the user's preference, and the way of dealing with different alarm levels for each user coming from a production management request, etc. Accordingly, the type of display mode can be set at different levels for each user.
