Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail based on preferred embodiments while referring to appropriate drawings.

[0025] 【Calendering device】

[0026] figure 1 It is a schematic diagram showing an outline of a rolling apparatus 2 according to an embodiment of the present invention. The calendering device 2 has a plurality of rolls 4 .

[0027] figure 1 The calendering device 2 shown has two rollers 4 arranged one above the other. In this rolling device 2 , the upper roll 4 and the lower roll 4 are arranged such that the axis UA of the upper roll 4 and the axis LA of the lower roll 4 are substantially parallel to each other. In the present invention, substantially parallel means that the angle formed by the axis LA with respect to the axis UA is in the range of 0° to 5°.

[0028] Although not shown in the figure, this rolling device 2 has a rotation unit (for example, a motor) that rotates the roll 4 at a predetermined rotation speed. In this...

Abstract

Provided are a monitoring device of a roller state, a calendering device, and a monitoring method of the roller state. The monitoring device (10) of the roller state is capable of recognizing that a temperature of a drill roll surface (8d) rises locally before a variation in thickness of a sheet occurs. The monitoring device (10) monitors the roller state of a calendering device (2) including a plurality of rollers (4). The plurality of rollers (4) are arranged such that their axes are substantially in parallel to each other, and include at least one drilled roller (6d) in which a flow passage(4) for flowing a fluid for adjusting a surface temperature is provided. The calendering device, while rotating the rollers, passes a polymer material through a gap of the rollers (4) to shape the polymer material. The monitoring device (10) of the roller state is provided with a temperature measuring means (12) for measuring a temperature of a rotating drilled roll surface (8d) and a determiningunit (18) for determining a state of a drilled roller (8d) based on a temperature distribution of a drilled roll surface (4d).

Description

technical field [0001] The present invention relates to a roll state monitoring device, a rolling device, and a roll state monitoring method. Background technique [0002] A calender is known as a molding machine for polymer materials such as rubber materials and plastic materials. The calendering device has a plurality of rolls arranged such that their axes are substantially parallel to each other. In the calendering device, while rotating these rolls, a polymer material is passed through gaps between these rolls to form a sheet or film having a desired thickness. [0003] When forming a sheet or film using a calendering device, it is required that the entire sheet or film obtained by the forming has the same thickness. Therefore, various studies have been conducted on techniques for suppressing variations in thickness. [0004] For example, in the following Patent Document 1, from the viewpoint of improving product accuracy, a technology capable of accurately grasping t...
