DETAILED DESCRIPTION OF THE INVENTION
A case will be described in which the embodiment of the present invention is applied to a multiple-unit management system for injection molding machines as shown in FIG. In FIG. 1, a plurality of injection molding machines 10-1 to 10-n are installed at the same place, and these are collectively managed by a management device 20 with a display device. That is, the management device 20 is connected to each control device in the injection molding machines 10-1 to 10-n, and various kinds of sensors from various sensors installed in the injection molding machines 10-1 to 10-n. Information is received via each control device, and the received information is processed for each injection molding machine based on a built-in management program, and the processed result is stored in a built-in memory and displayed on a display device as a management screen. Depending on the type of information, the received raw information is stored in the memory as it is.
[0015]
Next, four examples of a plurality of types of management screens displayed on the display device in order to represent the operating status of each injection molding machine in the management device 20 will be described.
[0016]
FIG. 2 is an operation status screen that displays the operation status of a plurality of injection molding machines in real time. On this operation status screen, the operating status of a plurality of injection molding machines is displayed on a single screen in real time for all the units (here, No. 1 to No. 30) in a screen division format. For example, referring to FIG. 3 showing the enlarged view of No. 9, the number of the No. machine is shown in the upper left, the count value C1 of the molding condition change counter is in the upper right (here, 17), and the operation state is 24 hours on the right. On the lower side of the graph, the number of shots (529) and the cycle time (14.9 sec) are displayed. Here, the molding condition change counter is a counter that counts how many times the molding conditions have been changed from the start of molding to the present. This counter is provided in the management device. The control device in each injection molding machine is provided with means for detecting a change in molding conditions. The management device receives the detection result from each control device, counts each, and displays the count result for each unit on the display device. . In the management apparatus, this display value can be reset as necessary.
[0017]
In addition, the 24-hour operating state graph is a single bar graph B1 that displays the operating state of the injection molding machine in the past 24 hours from the present time by color coding. The operation status is defined by four types: operation, normal stop (during standby), stop due to abnormality, and power off. The four types of status are displayed in different colors according to the passage of time from 24 hours ago to the present time. Is done. Here, operation is shown in blue, normal stop is yellow, stop due to abnormality is red, and power-off is shown in gray. In FIG. 3, blue is left-down hatching, yellow is right-down hatching, and red is satin The pattern and gray are shown as a mesh pattern. In addition, the lowermost end of the first bar graph B1 indicates 24 hours ago, and the uppermost end indicates the current time point. If there is, the first bar graph B1 is displayed with the lower half in yellow and the upper half in blue.
[0018]
Further, in this embodiment, the appearance of the injection molding machine is schematically displayed in the divided screen of each unit, and the background is based on the operation, the normal stop, and the occurrence of the abnormality to indicate the current operation state. The four types of stop and power off are displayed in the same color relationship as the color classification in the first bar graph B1. That is, if it is the same as the above example, the background color is blue.
[0019]
By looking at such an operation status screen, the operator or administrator can know at a glance which unit has been in what operating status in the past 24 hours. The numerical value of 24 hours is usually a fixed value, but may be variable.
[0020]
By the way, in the management apparatus 20, the summary graph screen which shows the operation | movement condition of only the applicable machine in detail by clicking the specific location (icon on a screen) in the division | segmentation screen of each car in the said operation condition screen in a display apparatus. It can be displayed.
[0021]
FIG. 4 shows an example of the summary graph screen. In this summary graph screen, the change status of quality data for 24 hours, presence / absence of abnormality, and presence / absence of setting change horizontally for each unit (here, No. 10). It is displayed on one screen as an axis. In FIG. 4, the uppermost graph is a line graph showing the change in the cumulative value of the number of shots, and a plurality of vertically entering lines, for example, the line L1, has a molding interruption (occurrence of anomaly) around 18:00. It shows that. The “state” of L2 is the same as the display of the operation state described above, and is defined by four types: operation, normal stop (during standby), stop due to abnormality occurrence, and power off, and 24 hours worth The status is displayed in different colors according to the time. The “condition name” of L3 is a graph showing the change time when the molding condition is changed, that is, when the condition name for each molded product is changed, the color is changed. In other words, this is changed when the molded product changes, and is displayed by color, but the color itself is not meaningful, but is meaningful at the time when the color changes. On the other hand, the “item” in L4 is a graph that displays the change in color with time when the condition item in the molding condition is changed. For example, the color is changed when an injection condition, a mold opening condition, or the like is changed, and this is also more meaningful at the time when the color changes rather than the color itself. For this reason, four or more colors are prepared for “condition name” and “item”, unlike “status”.
[0022]
Further, the first graph of L5 shows the elapsed time of the “filling time” of the display item shown in the display item selection column on the lower side of FIG. 4, and the second row similarly shows the time of “minimum cushion position”. Show progress. The third graph shows the “holding pressure completion position”, and the fourth and fifth graphs show the elapsed time of “VP switching position” and “pre-filling position”, respectively.
[0023]
Further, in this embodiment, the operating status of the unit in the past 24 hours is further displayed on the right side of the general graph screen with a numerical value indicating 24 hours by the second bar graph B2 at an operating rate of 0 to 100%. ing. FIG. 4 shows that the operating rate for the past 24 hours is 95%, and the operating rate calculation is based on “time display” shown in the display item selection column on the lower side of FIG. The number is displayed. The numbers in the “time display” column here can be arbitrarily changed. In other words, the “date and time” and “time display” shown in the display item selection field can be arbitrarily set, and here, a numerical value of 24 hours from 10:00 on September 4, 2000 is set. As shown in the uppermost part of FIG. 4, 24 hours from 10:00 on September 4, 2000 to 10:00 on September 5, 2000 are displayed. If the number “12” is entered in “time display”, the operation rate for the past 12 hours based on 12 hours is displayed in the second bar graph B2. In this case, the graphs or items in the first to eighth stages in FIG. 4 are also shown for the past 12 hours. According to such 2nd bar graph B2, the operation rate from arbitrary time of arbitrary time can be displayed.
[0024]
FIG. 5 shows an example of the setting history screen. In this setting history screen, the history of setting change is 1 for each unit (here, No. 10), together with the changed item, the setting value before and after the change, and the change date and time. Displayed on the screen.
[0025]
FIG. 6 shows an example of an abnormality history screen. In this abnormality history screen, the history of abnormality occurrence is displayed on one screen for each unit (here, No. 10) together with the item of abnormality, the occurrence date and time, and the release date and time. .
[0026]
As previously mentioned, the summary graph screen of FIG. 4 is linked to the operation status screen of FIG. 2, and is displayed by clicking a specific location (icon on the screen) of each unit on the operation status screen of FIG. It has come to be. Also, the setting history screen of FIG. 5 and the abnormality history screen of FIG. 6 are linked to the general graph screen of FIG. 4, respectively, and are displayed by clicking a specific part (icon on the screen) of the general graph screen of FIG. It has come to be.
[0027]
In addition, although said description is about the case where it applies to a multi-unit management system, it cannot be overemphasized that this invention is applicable not only to a multi-unit management system but to the case of only one injection molding machine. That is, the injection molding machine always includes a control device, and a monitor display device is connected to the control device. Then, the general graph screen as shown in FIG. 4, the setting history screen of FIG. 5, and the abnormality history screen of FIG. 6 can be displayed on this display device. However, since there is no operation status screen as shown in FIG. 2, the first bar graph as shown in FIG. 3 may be displayed instead of the second bar graph in the overall graph screen in FIG. In the case of only one injection molding machine, the control device and the display device are located in the immediate vicinity of the main body of the injection molding machine, so a screen schematically showing the appearance of the injection molding machine as shown in FIG. Is unnecessary. In other words, there is no need to display the operating status only at the present time.
[0028]
【The invention's effect】
As described above, according to the operation status display method of the present invention, the operation status and the operation rate can be easily confirmed at any time, and information according to the production operation rate base time can be easily understood. Therefore, such an operation status display method is optimal for a multiple-unit management system that collectively manages a plurality of injection molding machines.
