JPH01139460A - Device for adjusting curve of belt-like material and method thereof - Google Patents

Abstract

PURPOSE:To make it possible to facilitate the adjustment of curve of a belt-like material by arranging rollers having mechanisms by which the inclination and eccentricity of the rollers may be adjusted with respect to the piercing core surface of a processing roller train, in the latter so that a twist and an eccentricity are given to the belt-like material. CONSTITUTION:When a belt-like material 1 which is conveyed by rollers 5 through 7 between which the material is exerted with a tension, is curved, a roller between the rollers 5, 6 is inclined in such a direction that its concave- curved side moves away from the piercing core surface 2, and is pressed so as to increase the tensile strength of the material which is therefore allow to pass. Accordingly, a posterior curve in the material is eliminated. Further, if a widthwise eccentricity is produced in the band-like material 1, a roller 4 is inclined in the advancing direction and is driven so as to correct the eccentricity during the material being clamped for processing while a tension is effected between the rollers 6, 7. Thus, it is possible to facilitate the adjustment of a curve and an eccentricity.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a bend adjustment device and a bend adjustment method for a band-shaped material when the band-shaped material is compressed by a set of rollers and continuously processed.

(Prior Art) When a strip-shaped material is conveyed while being continuously compressed and formed between rollers, the strip-shaped material bends and inevitably deviates from the center of the rollers or the through axis. In the conventional method, the elongation was varied in the thickness direction by varying the roller gap, but
This is not preferable because it deviates from the original purpose of making the thickness of the strip material uniform in the width direction.

(Problems to be Solved by the Invention) The first object of the present invention is to provide a device that adjusts the bending of a strip-shaped material during pressure forming between roller sets by varying the tension distribution in the direction parallel to the roller axis. The purpose of A second object of the present invention is to provide a method of adjusting the bending of a strip material during pressure forming by varying the tension distribution in the axial direction of the roller using this device.

(Means 2 for Solving the Problems) The bending adjustment device of the present invention is as shown in FIG.

A mechanism is provided in the roller row that processes the strip material 1 to adjust the amount of inclination and eccentricity with respect to the threading shaft surface 2 of the roller row so that the strip material 1 is twisted and eccentric from the threading shaft surface 2. Roller 3. Alternatively, it is a device for adjusting the bending of a strip of material, which is equipped with rollers 4 or both. The inclination and eccentricity mechanisms for the rollers 3 and 4 are preferably such that the bearings at both ends of the rollers 3 and 4 are pushed up directly with cylinders or via levers.

To adjust the bending of a strip of material using the device of the invention,
Threading is carried out by pressing and displacing a roller inclined in a direction in which the curved side of the strip material 1 separates from the threading axis center surface 2 while applying tension to the strip material 1 between the roller sets 5, 6, and 7. 1. For example, when the strip material 1 is compressed between the roller set 5 and the roller set 6 while applying tension, if the strip material bends during this time, the side surface of the material will be pushed high. Tilt and push the roller 3 so that it can be lifted. This increases the tensile stress on the back side, making it easier for this part to be stretched by the previous roller set δ, eliminating the subsequent bend, and also making it easier for the preceding bend to be canceled by the roller set 6.This phenomenon occurs with a width of 210 mm.
Confirmed using paper.

When a strip material is continuously processed, in many cases, bending and eccentricity in the width direction occur at the same time. In such a case, the first
It is better to use rollers that are also inclined in the traveling direction, such as roller 4 in the figure, that is, roller set 6 and roller set 7.
If the roller 4 is driven with an inclination in the direction of travel while performing pressure processing while applying tension between The belt material tries to move forward under the force of the material. This phenomenon was confirmed using paper with a width of 210 mm.

The above phenomenon was confirmed when the strip material was paper, but the movement direction of the strip material in the width direction is the same regardless of the material, thickness, length, or degree of processing. It can be said that the bending adjustment device and bending adjustment method are effective for all kinds of materials, from light processing performed between rollers to mold processing. In addition, there are two or more roller sets.
L. The number of tiltable rollers may be one or more.

(Effects of the Invention) The device and method for adjusting the bending of a strip-shaped material of the present invention facilitates the bending adjustment of the strip-shaped material in the width direction, which was conventionally impossible or extremely difficult.

By the bending adjustment device of the present invention, it is possible to reduce the eccentricity in the width direction at the same time as the bending of the strip material.

Furthermore, the apparatus and method of the present invention not only make it possible to stabilize the shape and quality of the strip material, but also allow the strip material to pass through the center of a passage or at a desired position, and to manufacture a strip material with a desired bend. You can also do it.

(Field of Application of the Invention) The device and method for adjusting the bending of a strip-shaped material of the present invention can be applied to any process in which a strip-shaped material is continuously processed. In particular, paper processing processes in the paper industry;
Sheet manufacturing process in the plastic industry, plywood manufacturing process in the woodworking industry, thin plate manufacturing process in the metal industry, paper or sheet printing process in the printing industry 2. Strip material manufacturing process in the noodle manufacturing intermediate process in the food industry Used in manufacturing processes, magnetic tape manufacturing processes in the electronics industry, etc.
