Embodiment approach 1

[0037] figure 1 It is a figure which shows the structure of the system of Embodiment 1 of this invention. The diagnostic assistance device 1 of Embodiment 1 uses the calender 10 in the hot sheet rolling process as an object of diagnostic assistance. The calender 10 shown in FIG. 10 includes a heating furnace 21 , a rough calender 23 , a finish calender 26 , a coiler 28 , and a transfer table 29 . The material to be rolled 100 delivered from the heating furnace 21 is rolled by the rough rolling machine 23 . Rough calender 23 has one or several ( figure 1 The middle is 2) calendering frame 230. The rollers of each calender stand 230 are driven by a motor 231 . After being rolled by the rough calender 23 , the material to be rolled 100 is transferred to the finish calender 26 by the transfer table 29 . The rollers of the transfer table 29 are driven by a plurality of motors 291 . Fine calender 26 has 5~7 ( figure 1 There are 7 units in the center) rolling frame 260, which ...

Embodiment approach 2

[0070] Figure 9 It is a figure which shows the structure of the system of Embodiment 2 of this invention. In Embodiment 2, the diagnostic support device 1 is connected to a plurality of calenders 10A, 10B, 10C, and 10D installed in remote locations via the Internet 300 . The diagnostic assistance device 1 makes these rolling machines 10A, 10B, 10C, and 10D objects of diagnostic assistance.

[0071] In Embodiment 2, the diagnostic support device 1 collects data from the monitoring target devices of the rolling machines 10A, 10B, 10C, and 10D, analyzes them, and displays the analysis process and analysis results on the display device. In analyzing the data, the diagnostic support device 1 classifies the data obtained from similar monitoring target devices among the calenders 10A, 10B, 10C, and 10D into one group. For example, in the case where the calenders 10A, 10B, 10C, and 10D each have a fine calender composed of seven calender frames, the auxiliary diagnosis device 1 pro...

Abstract

A manufacturing equipment diagnosis support system according to the present invention is equipped with: a data collection device for collecting and recording respective data on multiple constituent devices to be monitored of the manufacturing equipment; a data analysis device for analyzing the recorded data; and a display device for displaying analysis processes and analysis results. The data analysis device is equipped with: a data analysis range setting unit for setting a data analysis range in the forms of data items and time; a data grouping unit for grouping the data through classification based on the specifications and use conditions of the devices to be monitored and classification based on physical quantities indicated by the data; a feature quantity extraction unit for extracting feature quantities in respective data items; an abnormal event identification unit for identifying an abnormal event candidate item indicating a different item from the others; and an examination unit for examining whether or not there is any significant difference between the abnormal event candidate item and the other data items.

Description

technical field [0001] The present invention relates to a manufacturing facility diagnostic support device for predicting in advance abnormalities and defects of devices in the manufacturing facility, such as a calender for rolling metal materials with calender rolls and a machining center for machining. Background technique [0002] As social infrastructure, there are many manufacturing facilities. Such as calenders, processing centers. Calenders are equipment that can be easily processed into automobiles and electric motors by rolling and thinning non-ferrous materials such as iron and steel, aluminum, and copper. The machining center is, for example, equipment that processes steel plates to manufacture aircraft, automobiles, various molds, and the like. [0003] For these manufacturing facilities, it is strongly required to be able to manufacture products stably and at high speed. Therefore, in order to avoid production failure due to failure of manufacturing equipment...
