ROLL BODY HANDLING SYSTEM, ROLL BODY SUPPLY METHOD AND ROLL BODY CONVEYING DEVICE

PROBLEM TO BE SOLVED: To smoothly receive a roll body from a roll body conveying device.SOLUTION: A roll body handling system has a roll body conveying automatic guided vehicle 100 which conveys a roll body having a hollow section, a turret for receiving the roll body from the roll body conveying automatic guided vehicle 100, and a controller 50. The turret includes a pair of chucks which are removable from the hollow section, a hollow section detection sensor, the relative position of which with respect to the chucks is fixed for detecting the hollow section, and a turret arm for moving the chucks between a plurality of stop positions including a receiving stop position to receive the roll body. When the roll body conveying automatic guided vehicle 100 moves the roll body toward a target position, the controller 50 calculates the amount of the movement of the roll body based on a detection result of the hollow section detection sensor, and a position relationship between the hollow section detection sensor and the chucks.
