Title:
ROLL PRESS FACILITY AND METHOD FOR CONTROLLING TEMPERATURE OF ROLLING BEARING THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/050258
Kind Code:
A1
Abstract:
The present invention addresses the problem of controlling thermal deformation of upper and lower press rolls, and enabling highly precise compression of a thin film material or the like for an electrode material for a secondary battery such as a lithium ion battery (LiB). In order to solve this problem, this roll press facility is characterized by being provided with: a pair of press rolls comprising an upper and a lower press roll, which are arranged opposing one another and between which a thin film material is compressed; first, second, third, and fourth rolling bearings, which pivotally support the respective end portions of the upper and the lower press roll; first, second, third, and fourth lubricating oil temperature adjustment means for adjusting the temperature of lubricating oil supplied respectively to the first, second, third, and fourth rolling bearings; a plurality of temperature sensors for detecting the temperature at a center portion and both end portions of the surface of the upper and the lower press roll; and a control means to which center portion temperature information about the surface of the upper and the lower press roll, and end portion temperature information about the surface of the upper and the lower press roll on the respective rolling bearing side, as detected by the temperature sensors, are input, and which, in accordance with the respective temperature information, outputs, to the respective lubricating oil temperature adjustment means, a command for adjusting the temperature of the lubricating oil respectively supplied to the respective rolling bearings.
