However, since the above-mentioned conventional technology electrically calculates the roll gap control value based on the wear of each roll and the roll gap, when starting the hulling operation and when replacing each roll, the initial reference value is The settings are extremely troublesome and there are problems with handling operations.In addition, simply displacing one roll using roll gap control changes the output of the detection roll that detects the wear of the roll on the side that is being displaced. It is necessary to distinguish between when the output is only roll wear, when it is only roll displacement, and when roll wear and displacement are combined, and it is necessary to simplify the circuit configuration for controlling the roll gap There was a problem in improving control accuracy.

Therefore, the wear detection value of each unrolling inputted through the detection roll and the link arm is summed by the displacement meter, and the roll gap of one unrolling inputted through the link plate and one link arm. Since the detected roll wear value is corrected using a displacement meter based on the amount of adjustment displacement, roll wear can be detected based on the displacement meter output at the start of work and at the time of roll replacement, and the initial setting of the reference value is much easier than in the past. In addition to being simple and easy to improve handling operability, motor control can be performed appropriately with simpler calculations than before based on the output of the displacement meter, and the circuit configuration for roll gap control is better than before. This makes it easy to simplify the process and improve the accuracy of roll gap control.

are connected to displacement meters 32 and 32a, respectively, and the motor 22 is operated and controlled based on the detection results of the displacement meters 32 and 32a to automatically control the roll gap C of each unrolling 3 and 4. The detection rolls 24, 24 and the link arm 23,
28, 45, 46 are input via the displacement meters 32, 32a, and the wear detection values are input via the link plates 13, 50 and one link arm 23, 45. Since the wear detection value of the detection roll 24 is corrected by the displacement meters 32, 32a according to the roll gap C adjustment displacement amount of one of the rolls removed 4, the output of the displacement meters 32, 32a at the start of work and when the rolls 3, 4 are replaced. The wear of the rolls 3 and 4 can be detected based on the displacement meter 3, and the initial setting of the reference value is extremely simple compared to the conventional method, and handling operability can be easily improved.
Based on the outputs of 2 and 32a, it is possible to properly control the motor 22 with simpler calculations than before, simplifying the circuit configuration for controlling the roll gap C and improving the accuracy of the control of the roll gap C compared to the past. This has the advantage that it is possible to easily achieve the following.
