Coiling controlling method

Abstract

The invention reduces a size of a machine and costs greatly by shortening length between an unwinding shaft and a winding shaft of a slitter or the like. When a web is unwound from the unwinding shaft and is rewound to the winding shaft as it is or when the web is cut in a plurality of strips of webs in a longitudinal direction, is separated in up and down directions or back and forth directions alternately, and is wound to upper and lower or back and front winding shafts, the unwinding shaft is driven and pays out at a set speed of the web, and the winding shaft is driven and winds with a set tensile force of the web. Guide rollers 2, 3 for guiding the web are provided between the unwinding shaft and the winding shaft, and the guide rollers 2, 3 rotates together by contacting with the web W without active driving.

Description

Technical field [0001] The present invention relates to a winding control method when a thin metal strip is drawn out from an unwinding shaft and wound on a winding shaft, and specifically relates to a longitudinal method of cutting and separating a wide metal thin strip into a plurality of narrow metal thin strips to be wound. Winding control method of cutting and shearing machine. Background technique [0002] As a device for winding a thin metal strip drawn from an unwinding shaft on a winding shaft, it has been known and widely used in the past to cut a wide metal thin strip into a plurality of narrow metal thin strips along its length direction. The slitting shear device in which the cut narrow metal thin strips are alternately separated up and down or back and forth and wound on the respective up and down or front and back winding shafts, such as figure 2 As shown, the winding control device of this slitting shear is generally provided with a brake 31 on the unwinding shaf...

Problems solved by technology

[0005] However, in the above-mentioned conventional method, since the lead-out roller of the lead-out part must tension the thin metal strip of the uncoiling part with an appropriate tension force, the frictional force between the thin metal strip and the surface of the lead-out roller and the amount of engagement between the lead-out roller and the thin metal strip must be provided. , the number of leading rollers and other important conditions, and involves complicated factors

[0006] In addition, although the pull-out part is tensioned with the tension necessary to wind the thin metal strip from the winding part, a pull-out device that prevents the thin metal strip from being deflected under this tension is required.
