METHOD AND DEVICE FOR WINDING PRODUCT WEB TO WINDING ROLL UNIT WHILE POSITIVELY DAMPING VIBRATION

摘要

PROBLEM TO BE SOLVED: To provide a resonator as a vibration suppression device relating to vibration of large mass, by performing a harmonic vibration by a frequency determined by a pressure dominant in a cylinder, at displacement time from a balance position of specific vibration suppressing mass. ;SOLUTION: In this vibration suppression device 70, a motion sensor 80 transmits a motion signal of a pressure bonding drum device or the like to a control unit 82, it determines a frequency of motion of the pressure bonding drum device or the like from a motion value. Next, in the control unit 82, so as to conform a frequency vibrated by exciting a vibration suppressing system to a frequency vibrated in the pressure bonding drum device or the like, bending rigidity of a vibration suppressing oscillator, having specific vibration suppressing mass MR, that is, compensation mass 54, is changed. Bending rigidity in the case of charging a cylinder with ideal gas is a function of pressure in the cylinder, the bending rigidity can be adjusted as desired. Accordingly, in accordance with a desired frequency or bending rigidity, a corresponding pressure is supplied to cylinders 60, 62 through a conduit 84.;COPYRIGHT: (C)1998,JPO
