DEVICE FOR CHANGING WIDTH OF ROLLER IN WIDE-FRANGE SHAPE STEEL ROLLER STRAITENER AND CHANGING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To easily and surely confirm the clutch-on only by attaching a simple means, by driving or stopping a motor for shaking to the normal or the reverse and the natural position with a three-positional type solenoid valve fitted to the shaking shaft of a shaking clamper and detecting the shaking angle with a sensor. ;SOLUTION: The clamper 1 is moved obliquely by working the shaking motor 6. The three-positional type solenoid valve 9 is positioned to the normal rotation side so as to flow oil to the shaking motor 6. The clamper 1 is pushed downward to the rear end part of a clutch lever 2 and a spring 3 becomes under compressing state and the upward force works at the tip part of the clamper, and an engage part 4 is taken out from the clutch 5 and becomes off-condition and a movable roller 13 can be shifted. A driving shaft 8 is rotated with another motor and the position of the movable roller 13 is changed to a prescribed position on a sleeve 16 of the driving shaft 8. The solenoid valve 9 is changed over to the neutral position and a working torque from the shaking motor 6 to the clamp 1 is stopped. The shaking angle is detected with the sensor 7 and in the case the shaking angle exceeds a threshold value, the clutch becomes on-condition.;COPYRIGHT: (C)1998,JPO
