  By the way, similarly to the construction machine described above, various sensors for monitoring the operating state are attached to a paper machine such as a corrugating machine that manufactures cardboard sheets. Then, the operation information detected by the various sensors is transmitted to a data server that stores the operation information. Here, since the paper processing machine uses paper as a processing object, processing unique to the paper processing machine such as paper cutting and paper drying is performed. For this reason, for example, when a sensor is provided in a portion where paper is cut, the paper dust generated by the cutting has an adverse effect on the sensor, and the detection accuracy is deteriorated. For example, when a sensor is provided in a portion where paper is dried, the heat generated by the drying has an adverse effect on the sensor, leading to deterioration in detection accuracy. Therefore, even if a sensor is provided in each part of the paper machine, it is necessary to perform fine maintenance, and the manufacturing cost of the paper machine increases due to the provision of the sensor. On the other hand, if a sensor is not provided in each part of the paper machine, the detailed operating state of the paper machine cannot be monitored. For this reason, the paperwork machine inspection work needs to be visually inspected by a skilled inspection worker using the operation information stored in the data server as a clue. As a result, when inspecting the paperwork machine, not only the operation information obtained from the various sensors of the paperwork machine but also a visual inspection by a skilled inspection worker is required. difficult.

As a result, the real-time information transmission means can store the extracted operation information within the allowable range of the data transmission capacity on the network, and thus can appropriately transmit the operation information to the information management device in real time. On the other hand, since the operation information stored in the information storage unit has a large amount of information, the periodic information transmission unit transmits the operation information stored in the information storage unit while the operation of the paper machine is stopped. As a result, the periodic information transmission unit can transmit the operation information stored in the information storage unit without adversely affecting the transmission of the operation information by the real-time information transmission unit.

It should be noted that, by predicting the replacement time of each part based on the predicted failure time of each part, if the parts of the paper processing machine 5 that are close to the failure time are prepared in advance, the replacement of each part of the paper processing machine 5 is performed. It can be done smoothly.

  When it is determined that a problem has occurred in the paper machine 5, the defect factor specifying unit 92 calculates a correlation between the defect information accumulated in the defect database 101 and a defect factor that causes a problem in the paper machine 5. In addition to the analysis, the analysis result obtained by the analysis is compared with the obtained operation information and inspection information to identify the cause of the failure. Here, as the failure factors, for example, a productivity hindrance factor that hinders the productivity of the paper machine 5, a production loss factor that causes a production loss of the paper machine 5, and a product produced by the paper machine 5 There are quality deterioration factors that cause a quality deterioration event and defective parts among the parts constituting the paper machine 5.

Build a specific model. In other words, the inhibition factor specifying model is a model of defect information that is highly correlated with the productivity inhibition factor. Then, the inhibition factor identification unit 110 identifies the productivity inhibition factor by applying the inhibition factor identification model to the acquired defect information (operation information and inspection information).

  Here, the sticking failure of the liner paper to the core paper, which is a kind of productivity impediment factor, will be specifically described as an example. When the liner paper sticking failure to the core paper occurs as a productivity impediment factor, the operator operating the paper processing machine 5 eliminates the sticking failure by reducing the conveyance speed of the corrugated cardboard sheet in the corrugating machine 15, for example. . At this time, the speed detection sensor 44 provided in the paper processing machine 5 detects that the conveyance speed is decreasing, and this detection signal is sent to the information management device 8 via the operation information collection device 6 and the network 9. Obtained as operation information by the information communication unit 83. Thereafter, when it is determined that a failure has occurred in the paper machine 5 based on the acquired operation information, the inhibition factor identification unit 110 causes a highly correlated productivity inhibition factor, that is, a core caused by a decrease in the conveyance speed.

First, the information management device 8 presets the type of operation information collected in the operation information collection device 6 (step S11), and instructs the operation information collection device 6 to collect the set type of operation information. Then, the operation information collection device 6 starts collecting operation information of the paper machine 5 (step S1), and transmits the collected operation information to the information management device 8 (step S2). At this time, real-time data is transmitted from the operation information collection device 6 to the information management device 8 during operation of the paper machine 5. On the other hand, when the operation of the paper machine 5 is stopped, detailed data is transmitted from the operation information collection device 6 to the information management device 8.

At this time, the inspection worker performs the inspection work according to the inspection program stored in the inspection portable terminal 7 and inputs the inspection result to the inspection portable terminal 7. Thereby, the portable terminal 7 for inspection acquires the input inspection result as inspection information (step S32). After completion of the inspection work, the inspection operator operates the inspection portable terminal 7 to transmit inspection information from the inspection portable terminal 7 to the information management device 8 (step S33).

  When the operation information is transmitted from the operation information collection device 6 and the inspection information is transmitted from the inspection portable terminal 7, the information management device 8 acquires the operation information and the inspection information (step S12). Then, the information management device 8 analyzes the correlation between the acquired operation information and inspection information and the occurrence of the failure of the paperwork machine 5 so that the failure determination unit 90 can determine the failure of the paperwork machine 5 (step S13). . The operation information and inspection information acquired in step S12 and the data obtained by analysis in step S13 are stored and saved in the information database 100 (step S14). Thereafter, the information management device 8 performs the failure determination of the paperwork machine 5 by the failure determination unit 90 (step S15), and if it is determined that no failure has occurred in the paperworking machine 5, the operation information collection device 6 generates the inspection report. The inspection report data is generated by the unit 60 (step S3), and the created inspection report data is printed (step S4).

  On the other hand, if the information management device 8 determines that a problem has occurred in the paper machine 5, the defect information in the defect database 101 is correlated with the defect factor so that the defect factor identifying unit 92 can identify the defect factor. Is analyzed (step S16). When the failure factor is specified by the failure factor specifying unit 92, the information management apparatus 8 uses the failure of the paper processing machine 5 for eliminating the failure factor by the failure factor eliminating unit 93 in order to eliminate the failure factor that causes the failure. The adjustment part is specified, or the replacement of the defective part specified by the defect factor specifying unit 92 is instructed (step S17).

  Subsequently, the inspection worker replaces defective parts of the paper processing machine 5 or adjusts the adjustment part of the paper processing machine 5 in accordance with the adjustment command or replacement command received by the mobile terminal 7 for inspection. 5 is eliminated (step S34). Thereafter, the inspection worker inputs repair information related to the repair work that has solved the problem of the paper machine 5 to the mobile terminal 7 for inspection (step S35). Then, the inspection operator operates the inspection portable terminal 7 to transmit the repair information from the inspection portable terminal 7 to the information management device 8, and the repair information is transmitted from the inspection portable terminal 7 to the operation information collecting device 6. (Step S36).

  The operation information collection device 6 that has received the repair information generates inspection report data based on the received repair information by the inspection report creation unit 60 (step S5) and performs printing based on the created inspection report data. Thus, an inspection report is created (step S6). On the other hand, the information management device 8 that has received the repair information stores the received repair information in the information database 100 of the storage unit 81 (steps S18 and S19).

For this reason, as the defect information is accumulated in the defect database 101, it becomes possible to improve the prediction accuracy of the defect time of each component by the defect time prediction unit 91.

  Furthermore, the information management device 8 specifies a failure factor that causes the failure of the paper machine 5 by the failure factor specifying unit 92 and eliminates the specified failure factor of the paper machine 5 by the failure factor eliminating unit 93. The paper machine 5 can be suitably operated.

  In addition, the operation information periodically sampled by the operation information collecting device 6 is transmitted as real time data to the information management device 8 in real time by the real time information transmitting unit 64, while the periodic information transmitting unit 65 is transmitted as detailed data. The information can be transmitted to the information management device 8 while the operation of the paper machine 5 is stopped.
