Claims

[Claims for Utility Model Registration] A device for controlling the tension when a rolled material that has been rolled or rolled in a rolling mill is unwound from a reel that is rotationally driven by a motor, or when it is wound up on a reel, a tension control main control means for controlling the tension of the material to be rolled based on a tension signal fed back from a tension meter that detects the tension of the material to be rolled; a pulse generator for detecting the rotational speed and rotational position of the reel; a digital motor drive device that controls the rotation of a motor that rotationally drives the reel based on a tension control signal from a tension control main control means and a rotation speed signal of the reel from the pulse generator; an outer diameter measuring device that measures the outer diameter of a coil; and a reel that calculates and controls the axis position of the reel based on a coil outer diameter signal from the outer diameter measuring device and a rotational position signal of the reel from the pulse generator. a shaft center position control means; a hydraulic control system that operates based on a control output signal from the reel shaft position control means; and a command signal from the hydraulic control system to freely move the reel shaft center in a vertical direction. A tension control device for a rolled material, comprising: a hydraulic cylinder that controls the tension of a rolled material;
