Method for coiling steel strip and device therefor

鋼帯の巻き取り方法およびその装置

Abstract

PROBLEM TO BE SOLVED: To prevent generation of end mark in a steel strip by continuously executing correcting control of the positional deviation between the tracking position of the tip of the steel strip and the position of step adjusting part. SOLUTION: The steel strip 1 is coiled with a mandrel 6 on which a sleeve 7 with step adjusting part is armored. Then, the position of the tip of the steel strip 1 in advancing, moving speed and the position of the step adjusting part in revolving are respectively detected with detectors C1, C2, C4. The rotational angle and speed of the mandrel 6 are controlled so that the position of the step adjusting part in revolving is mated with the position of the tip of the steel strip in advancing. Just before starting coiling, the position of the tip of the steel strip 1 is again detected with the detector C1 and correcting control is executed so as to eliminate the positional deviation between the position of the tip of the steel strip and the position of the step adjusting part. Further, even after the steel strip is wound around, the correcting control of the positional deviation between the tracking position of the tip of the steel strip 1 and the position of the step adjusting part is continuously executed. In this way, the yield of products is improved.
(57)【要約】 【課題】鋼帯を段付き部または空洞部付き等の鋼帯先端 の段差調整部付きスリーブを外装したマンドレルに巻き 取るに際し、鋼帯先端とスリーブの段差調整部との位置 合わせを高精度に行って、鋼帯のエンドマーク発生を防 止する鋼帯の巻き取り方法およびその装置を提供する。 【解決手段】 進行中の鋼帯先端位置および移動速度、並びに回転中 の段差調整部の位置を検出する。 その進行中の鋼帯先端位置に回転中の段差調整部の位 置が合うようにマンドレルの回転角度および速度を制御 する。 巻取り開始直前に、再度鋼帯の先端位置を検出する。 前記の鋼帯先端位置の検出値で鋼帯先端のトラッキ ング位置を補正する。 鋼帯先端のトラッキング位置と段差調整部位置との位 置偏差を無くするように修正制御する。 さらに、巻付け開始後も鋼帯先端のトラッキング位置 と段差調整部位置との位置偏差を無くする修正制御を継 続して行う。
