Title:
WINDING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/033996
Kind Code:
A1
Abstract:
A winding control system according to one embodiment comprises: a motor drive control device that controls the driving of a motor which rotationally drives a mandrel for winding a rolled material around a coil; a tail end sensor that detects one point of the rolled material to thereby output a detection signal indicating that the rolled material passes through a tail end; a winding control device that tracks the position of the tail end; a first camera that is provided between the finishing roll mill and the mandrel and captures images for first image data including information about the shape of the tail end; and an image analysis device that performs image analysis on the first image data at a timing at which the detection signal is emitted, generates a correction value for correcting the position of the tail end on the basis of a result of the image analysis of the image data, and outputs the correction value to the winding control device. The winding control device corrects the position of the tail end by using the correction value.
