Abstract

[Challenge] To effectively eliminate bottlenecks in the production process by comprehensively and thoroughly understanding the operating rate of injection molding machines and making appropriate adjustments based on accurate analysis. [Solution] The system includes an operation data acquisition means 2 that acquires the operating time of an injection molding machine M during normal fully automatic operation as actual operating time data Ts, and acquires the non-operating times of the injection molding machine M corresponding to multiple different non-operating states during normal or abnormal conditions as multiple different non-operating time data Tna, Tnb, Tnc..., and an operation data display means 3 that graphically displays the actual operating time data Ts and multiple different non-operating time data Tna... acquired by the operation data acquisition means 2 on the display 11 of the molding machine controller 10 or a management computer 10e other than the molding machine controller 10.

Description

This invention relates to an injection molding machine operation management system suitable for use in managing the operating status of an injection molding machine. Generally, managing the operational status of injection molding machines is crucial. In particular, users typically report production information, anomaly occurrences, and other relevant data to the appropriate management section or technical center, and request necessary support accordingly. Conventionally, a management system for managing such operating conditions is known, specifically the injection molding machine operation management system and operation management method described in Patent Document 1. This operation management system aims to perform accurate operation management efficiently and effectively, as well as to perform quick and appropriate troubleshooting. Specifically, it acquires operation data related to the operating status of the injection molding machine, stores the acquired operation data at least temporarily in the molding machine controller, and creates user data including operation data for a predetermined period, identification data to identify this operation data, and a destination on the Internet for transmitting the operation data and identification data. This user data is then stored in an information storage code using a graphic pattern, which is displayed on a display attached to the molding machine controller.

Next, preferred embodiments of the present invention will be described in detail with reference to the drawings. First, the overall system configuration of the operation management system 1 according to this embodiment will be explained with reference to Figures 2 and 3, and further to Figures 4-8. Figure 2 shows a schematic configuration of an injection molding machine M equipped with an operation management system 1, and Figure 3 shows the control system block configuration of the injection molding machine, including the main components of the operation management system 1. In Figure 2, M represents an injection molding machine, which comprises a base Mb, an injection device Mi, and a mold clamping device Mc, both mounted on the base Mb. The injection device Mi includes a heating cylinder 51, with an injection nozzle (not shown in the figure) at its front end, and a hopper 52 for supplying molding material at its rear. The mold clamping device Mc includes a mold 53 consisting of a movable mold and a fixed mold. Furthermore, the injection molding machine M incorporates the molding machine controller 10 shown in Figure 3, and, as shown in Figure 2, a display 11 attached to the molding machine controller 10 is mounted using the side panel 54 provided on the machine base Mb. This display 11 is connected to the display port of the controller body 21, for example, by using a liquid crystal display with a touch panel. The display 11 can display display screens V1 and V2 related to the operating rate using graphic displays as shown in Figures 4 and 5, as well as the setup process selection screen V10 shown in Figure 6, the forced defect molding process mode selection screen V11 shown in Figure 7, and the sampling process operation screen V12 shown in Figure 8.
