[0047]
Next, the flow of information in the molding machine management system according to the embodiment of the present invention realized by the management device 20 having the above-described function, the PDA 30 and the like will be described with reference to FIGS. Here, FIG. 6 is a first sequence diagram showing a flow of information in the molding machine management system according to the embodiment of the present invention, and FIG. 7 shows information of the molding machine management system according to the embodiment of the present invention. It is a 2nd sequence diagram which shows a flow. In the embodiment of the present invention, information is transmitted by causing a program installed in the management device 20 and a program installed in the PDA 30 to be executed.
[0048]
Referring to FIG. 6, constantly logged data is sent from the injection molding machines 10-1 and 10-2 to the management apparatus 20 (S11), and is registered in the database in the management apparatus 20 (S12). Here, the logging data is information regarding the operations and states of the injection molding machines 10-1 and 10-2. The logging data is sent from the various sensors installed in the injection molding machines 10-1 and 10-2 to the management apparatus 20 via the control devices of the injection molding machines 10-1 and 10-2.
[0049]
Further, the PDA 30 can be connected to the injection molding machine 10 wirelessly or by wire without using the management device 20, and the setting conditions of the injection molding machines 10-1 and 10-2 can be changed from the PDA 30 (S13). In this case, the setting conditions stored and stored in the injection molding machines 10-1 and 10-2 are edited. The change of the setting condition is transmitted as a setting change history from the control device inside the injection molding machine 10 to the management device 20 (S14), and the setting change history is registered in the management device 20 (S15).
[0050]
As described above, by using the PDA 30, it is possible to easily change the setting for the injection molding machine 10-1 or 10-2 from any place in the manufacturing factory.
[0051]
When an abnormality has occurred in the injection molding machine 10-1 or 10-2, the history of operation abnormality (abnormality occurrence history) such as the number of the injection molding machine in which the abnormality has occurred, the content of the abnormality, the time of occurrence of the abnormality, The information is transmitted from the injection molding machine 10-1 or 10-2 to the management device 20 (S16) and registered in the management device 20 (S17). That is, since the management apparatus 20 has built-in management software, the management apparatus 20 processes the acquired information for each injection molding machine based on the management software and stores it in a memory built in the management apparatus 20. . Then, as shown in FIG. 5, the abnormality occurrence history is displayed on the display device of the management device 20 as a management screen.
[0052]
Further, the contents of the abnormality occurrence history are transmitted to the PDA 30 corresponding to the unit where the abnormality has occurred via the wireless LAN (S18). FIG. 8 is a diagram showing a screen (stop list screen) 60 of the PDA 30 on which an abnormality occurrence history is displayed.
[0053]
Referring to FIG. 8, on the stop list screen 60, by pressing the display switching button 61, it is possible to display the cause of the stop that is one time old or new, and display the stop causes of the past 10 items in total. Can do. On the stop list screen 60, items such as molding conditions, states, stop time due to abnormality, occurrence time of abnormality, restart time, content of abnormality, supplement of abnormality, peripheral device, cause of abnormality, memo, and the like are displayed.
[0054]
As described above, the operator having the PDA 30 can confirm the contents of the abnormality occurrence in real time via the stop list screen 60 of the PDA 30 even when the operator is away from the injection molding machine where the abnormality has occurred. In other words, information such as the occurrence of an abnormality can be shared in real time by the administrator of the management apparatus 20 and the operator in the manufacturing plant, and the occurrence of the abnormality can be quickly dealt with, thereby improving the production quality and the operating rate of the equipment. In addition, work efficiency can be improved.
[0055]
Incidentally, in addition to the above-described abnormality occurrence history, the following work instruction information can also be transmitted from the management apparatus 20 to the PDA 30.
[0056]
For example, among the product information produced by the injection molding machine 10-1 or 10-2 in the management device 20 by an administrator or the like, “from which injection molding machine will produce what product to when” When the work instruction information such as “What is the material necessary for the production”, “What is the mold necessary for the production”, “What is the expected number of shots”, etc. is input, Then, it is transmitted from the management device 20 to the PDA 30 of the corresponding injection molding machine 10-1 or 10-2 via the wireless LAN (S19).
[0057]
FIG. 9 is a diagram showing an example of a screen (work instruction information screen) 70 of the PDA 30 on which such work instruction information is displayed. Referring to FIG. 9, the work instruction information screen 70 of the PDA 30 includes the name of the worker who uses the PDA 30 (worker number), the number of the molding machine to work on, the name of the product to be manufactured, the molding conditions, the mold to be used, Work instruction information such as the material to be used and the planned production number is displayed. Accordingly, the management device 20 can transmit information such as work instructions to the operator in real time via the PDA 30 wherever the operator is located. The operator can confirm the work instruction information displayed on the display of the PDA 30. The next production preparation and production can be performed in real time.
[0058]
After confirming the work instruction information, the operator reports a confirmation from the PDA 30 and transmits it to the management device 20 (S20). Thereby, in the management apparatus 20, it is possible to easily know who is confirming the work instruction and performing the work.
[0059]
In place of the work instruction information, the production plan change instruction information can be transmitted in the same flow. Therefore, for example, when a situation in which the production plan must be changed urgently occurs, even if there is no operator at the production site, the change of the production plan is notified from the management device 20 to the operator via the PDA 30. can do. As described above, in the present embodiment, accurate and sufficiently accurate information related to the production plan change can be transmitted to the operator, so that a quick and reliable response is possible.
By the way, in addition to the above-described report of confirmation of the work instruction information, the PDA 30 can also transmit molding condition information which is a setting condition of the following molding machine.
[0060]
That is, information on molding conditions and molding schedule, which is the information that can be best grasped by the operator present at the molding site, specifically, information on the mold to be used next, which functions as equipment for the work device, Information regarding the resin to be used, product information, the number of scheduled shots, delivery date (scheduled for completion), etc. is transmitted from the PDA 30 to the management apparatus 20 (S21). Information regarding the molding operation (molding condition information) is registered in the management device 20 (S22) and transmitted from the management device 20 to the corresponding injection molding machine 10-1 or 10-2 (S23).
[0061]
For example, a bar code is attached to the mold of the injection molding machine 10-1 or 10-2 as mold information. Further, the relationship between the mold barcode and the molding conditions is registered in the management device 20 in advance. The operator inputs information on the mold barcode into the PDA 30 to instruct the management apparatus 20 to upload the necessary molding conditions (S21). The management apparatus 20 then injects the injection molding machine 10-1 or 10-. The necessary molding conditions are uploaded in step 2 (S23).
[0062]
Conventionally, the molding condition information has been transmitted to the administrator by paper, but by using the PDA 30 in this way, the operator can easily transmit in real time from any location in the manufacturing factory, Furthermore, it can contribute to paperlessness at the molding site.
[0063]
By the way, conventionally, when the injection molding machine 10-1 or 10-2 is stopped,
Various information generated during production at the molding site, for example, when the mold is damaged during production, trouble situation in various facilities, quantity of work in progress and situation at the time of trouble, stop of injection molding machine Information regarding the cause could not be sent to the management device 20 in real time. That is, although the management apparatus 20 can recognize the fact that the injection molding machine 10-1 or 10-2 has stopped, it has not been able to grasp the cause of the stop.
[0064]
However, when the operator inputs and transmits information regarding the cause of stoppage to the PDA 30 of the present embodiment, the information can be sent to the management device 20 in real time.
[0065]
Hereinafter, stop cause input and information transmission using the PDA 30 will be described with reference to FIGS. Here, FIG. 10 is a diagram showing the machine number selection screen 80 of the PDA 30. FIG. 11 is a diagram showing the stop cause editing screen 85 of the PDA 30.
[0066]
First, when an operator inputs an ID given to himself / herself on a predetermined login screen of the PDA 30 and logs in, the display switches to a machine selection screen 80 shown in FIG.
[0067]
The name of the operator is displayed on the unit selection screen 80, and the operator can select the target unit by the unit selection item 81, and the selection is confirmed by pressing the selection button 82. When the selection target is confirmed, the stop list screen 60 shown in FIG. 8 in the injection molding machine of the selected number is displayed.
[0068]
As described above, in the stop list screen 60 shown in FIG. 8, the molding condition, state, stop time due to the above, occurrence time of abnormality, restart time, content of abnormality, supplement of abnormality, peripheral device, cause of abnormality, memo Etc. are displayed.
[0069]
By pressing the edit button 62 on the stop list screen 60, the stop list screen 60 is switched to an edit screen 85 shown in FIG. In the edit screen 85, in addition to the items shown in FIG. 11, it may be set so that the quantity and status of work-in-progress when an abnormality occurs can be input.
[0070]
When the operator edits the supplement of the abnormality, the peripheral device, the cause of the abnormality, and the memo on the edit screen 85 and presses the registration button 86, stop cause information is transmitted to the management device 20 as shown in FIG. S24), all are registered in the management apparatus 20 (S25).
[0071]
As a result, the situation at the molding site such as information about the cause of stoppage is inputted and recorded in real time, and is used for preparation of daily reports, weekly reports, monthly reports and the like. These pieces of information are sent to the management apparatus 20 separately from the information sent from the injection molding machine 10-1 or 10-2 to the management apparatus 20.
[0072]
As a response to the transmission of the stop cause information to the management apparatus 20, an edit result display screen is transmitted to the PDA 30 (S26), and is displayed on the PDA 30 as a stop list screen 60 (see FIG. 8). The operator can check the stop list screen 60 and grasp that all the contents edited by the operator are registered in the management apparatus 20.
[0073]
In this way, information regarding the cause of stoppage that cannot be grasped only by the management apparatus 20 can be transmitted to the manager of the management apparatus in real time, and such information can be shared with the operator in the manufacturing plant. Therefore, even if a situation where the production plan must be changed urgently occurs at the molding site, the operator can report the fact to the management apparatus 20 via the PDA 30. Furthermore, since the operator can also obtain information on the cause of the stop that has already been accumulated in the management device 20, a quicker response can be achieved. As a result, productivity can be improved, equipment availability can be improved, and work efficiency can be improved.
[0074]
