Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • forces of an actuator i.e. secondary forces the purpose of which can be to cancel primary forces (actual damping of vibration) or to prevent the transfer of an excitation of a part of the machine into the other structure (active isolation of vibrations).
  • Feedforward active damping will not change the mechanical properties of the system, such as mass, rigidity and damping.
  • feedforward vibration damping In feedback active damping of vibration, primary forces directed at a structure are not required to be/cannot be measured.
  • the measured variable is a vibration response (displacement, speed or acceleration) of the structure caused by the sum of both primary and secondary forces.
  • This vibration response is entered via a chosen transfer function to be an instruction for the actuator (actuators).
  • Feedback active damping changes the response of the structure at resonance points so that e.g. damping increases.
  • Feedforward vibration damping requires thus a direct or indirect measurement of primary forces, which can be extremely difficult on winders, e.g. on winder parts of slitter-winders, where there are several independent excitation sources (rolls, customer reels which can all rotate at a different rotating frequency being of different diameters etc.).
  • feedforward control can never stabilise an instable system i.e. feedforward damping of vibration cannot damp vibration cases caused by instability.
  • feedforward control has to be adaptive in order to be able to react to changes in the primary forces (e.g. the rotating frequency of a growing reel decelerates continuously). Finding an adaptive control algorithm for a naturally nonlinear slitter- winder is challenging if not impossible.
  • Measuring the reference signal of primary force is performed by measuring the vibrating structure with a vibration transducer. By a calculation algorithm, a control signal of the element is calculated from this reference signal which signal damps the vibration being conveyed from the vibrating structure to the hydraulic cylinder.
  • the method essentially corresponds the isolation of the vibrating component from the other structure.
  • a full-width web is cut in the longitudinal direction into partial webs, after which the partial webs are wound on the winder part of the slitter- winder around winding cores e.g. spools into customer reels.
  • carrier-roll and multistation winders are used in winding customer reels i.e. partial reels.
  • the partial web is wound around the winding core by means of a winding nip between the winding roll and the web reel being formed, and the winding core of the web reel being formed is provided with a centre drive.
  • the slit partial webs are wound around the winding cores supported by two rolls or by one roll and one set of rolls or by two sets of rolls.
  • carrier roll is used for simplicity when referring to a support roll/set of rolls of a winder of carrier roll type i.e. including both the meanings of a carrier roll and a set of carrier rolls.
  • carrier roll winders of variable geometric which one or both of the carrier rolls carrying the reel are displaceable.
  • the central horizontal location of the reel being formed depends on the position of the carrier rolls in respect to each Dther and the diameter of the reel.
  • a pressure roll In connection with winders, a pressure roll has Deen used, first, with small reel diameters to produce the required nip load and, after the mass of the reels has grown large enough, when the pressure roll is no longer required because of nip load, the pressure roll has been kept connected on the reels until the finish of winding with a small load for keeping the reels in place, for them not to be able to become loose or fly out of the winder because of vibration or bouncing.
  • the strong vibration of a pressure-roll beam frequently causes the reels to become eccentric or rectangular, whereby the vibration transfers also to the other parts of the winder. Also the out-flying risk of the reels increases as the pressure-roll beam vibrates intensively.
  • the object of the invention is to provide a method for damping vibrations on a winder, especially on the winder of a slitter- winder.
  • the object of the invention is to create new arrangements based on feedback active damping for damping vibrations occurring on winders.
  • a method according to the invention is mainly characterised by what is presented in the characterising part of claim 1.
  • at least one component of the system undergoes feedback active damping of vibration, and there is at least one feedback signal and it measures the vibration of one or some components of the system i.e. motion, speed or acceleration, and the feedback signal is controlled via a transfer function to be a control signal for the actuator or actuators.
  • the vibration of carrier rolls/winding roll is damped advantageously by actuators installed below bearing housings and/or the vibrations of a pressure-roll beam are damped using its own relief cylinders and/or the vibrations of the pressure-roll beam is damped by putting an actuator between a carriage and the beam.
  • the bearing housing can be pivoted of its one end and, at the other end, there can be an actuator.
  • actuators can advantageously be used, inter alia, hydraulic, pneumatic, piezoelectric or magnetostrictive actuators and e.g. AC servo motors.
  • a feedback active damping system the control of which is implemented so that one tries to keep the motional amplitude of vibration as small as possible by increasing damping at resonance points by feedback active damping.
  • the invention can be applied e.g. in carrier rolls and winding rolls, whereby the actuator can be e.g. below the bearing housing or bearing-mounted on the shaft of the roll.
  • the actuator can function a relief cylinder of the pressure-roll beam and an actuator placed between a carriage travelling by frame guides and the pressure-roll beam itself.
  • the load hydraulics of the pressure-roll beam is used in the active damping of guide- directional vibrations.
  • the vibration frequency range of the pressure-roll beam is usually less than 20 Hz, typically 15-20 Hz, for which range hydraulics is especially suitable.
  • Damping guide-directional vibrations of the pressure-roll beam is an advantageous exemplifying embodiment of the invention, because when vibrating the beam is able to remain quite rigid in the direction of the guide, whereby the load of hydraulic cylinders moves the whole beam evenly.
  • the arrangement is extremely advantageous, because it requires in principle no more than a strategy of active damping control.
  • the pressure-roll beam is supported hydraulically and on the central area of the pressure-roll beam is placed a vibration transducer which is used as a feedback signal and as the actuators are used the hydraulic cylinders of the pressure-roll beam intended for loading.
