Definitions

  • the invention relates to a winding machine for winding a material web, in particular a paper or board web, on at least one winding tube to a winding roll by means of at least one mounted roller on which the winding roll when winding up or rests, at least one in one of pivot arms held traverse mounted pressure or load roller for exerting a contact pressure on the at least one winding roll is present.
  • Material webs must be wound up on shipping or finishing rolls before they can be shipped.
  • reel cores usually winding cores are used, which are preferably made of cardboard.
  • the finished rolls are produced by so-called mother or spool rolls, which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores.
  • mother or spool rolls which are produced at the exit of a paper machine or after the calendering, unwound, cut in the longitudinal direction and then wound on each winding cores.
  • These cores are either on a support roller of a back-up roll winding machine or laterally on this, or the cores are in one of two support rollers of a double carrier roll winding machine formed winding bed.
  • vibrations in a roll winding device also lead to the formation of runout of the winding roll.
  • Out-of-roundness may be associated with the processing of certain types of paper.
  • the frictional behavior or the paper thickness are relevant variables. It is assumed that contact vibration between the winding roll and the roll or rolls is the cause for the ovality of the winding roll, wherein the roll or rolls and the winding roll or parts thereof, for. B. the outer paper layers of the winding roll, swing against each other. This can lead to a non-uniform structure of the winding roll (density, stiffness, thickness variation, air pockets, shifting paper layers), which in turn can increase the contact vibrations.
  • the pressure roller also has a significant influence on the quality of the wound paper web and on the roundness of the roll.
  • their pressure to the winding roll and the position of the pressure roller are controlled by hydraulic cylinders. Because the entire mass of the pressure roller traverse must be moved along, no high dynamics of this control is possible. On Vibration or irregularities of the roll can not be reacted, the line force exerted by the pressure roller on the winding roll, the set value can not follow.
  • this object is achieved in a winding machine of the type mentioned above in that the pivot arms which receive the pressure roller carrying cross member are connected to a force or position control and that the position of the pressure or load roller against the winding roll by a with their storage in the Traverse connected damping device relative to the winding roll is adjustable.
  • the traverse of the pressure roller is further moved in a known manner via hydraulic cylinders or equivalent drive means such as an electrically adjustable spindle to determine the approximate position of the pressure roller relative to the winding roller.
  • drive means such as an electrically adjustable spindle to determine the approximate position of the pressure roller relative to the winding roller.
  • a damping device for damping vibrations of the pressure roller is provided in the region of the bearing of the pressure roller in the Traverse. Because these damping properties can be varied very quickly and instead of the total mass of the traverse and the pivot arms including the pressure roller only the small mass of the pressure roller or alternatively the pressure roller has to be moved in connection with their storage, the pressure roller can follow the movement of the winding roll very well. This means that the pressure roller can optimally compress the discontinuities of the winding roll.
  • pressure roller Even if only the term "pressure roller” is always used below, this does not exclude the possibility that a large number of pressure roller segments mounted side by side between the same pivoting arms or in each case via individual pairs of pivoting arms can be present.
  • the device for force or position control of the pivot arms is connected to the pivot arms pivoting pneumatic or hydraulic cylinders or electrically operated spindles or to the bearings of the pivot arms themselves.
  • This force or position control has little dynamics, but it provides for the compensation and damping of low frequency vibrations.
  • the damping device comprises at least one actuator, in particular a hydraulic, pneumatic, electrorheological actuator or an electric linear drive.
  • the damping device comprises a cylinder and a piston arranged therein, which divides the cylinder into two pressure chambers, wherein the piston with the roller bearings and the cylinder with the crossbar is in communication and the two pressure chambers via a Link are connected, which contains at least one throttle.
  • Another advantage is that a switching valve is arranged in the connecting path, with which the connection path can be interrupted.
  • the circulation device advantageously has a tempering device.
  • An additional advantage is achieved by connecting the two pressure chambers with each other, for which purpose a pressure compensation throttle is used.
  • the pressure compensation throttle can be easily arranged in the piston itself.
  • a further advantageous embodiment of the invention is that the damping device is connected to a control or regulating unit and that the control or regulating unit, the force with which the pressure or load roller rests on the winding roll, and / or the distance that the Compressing or loading roller during the rotation of the winding roll has, as control variables for adjusting the damping can be fed.
  • the pressure or support roller at least one actuator for measuring the contact pressure or the supported weight of the winding roll and / or the distance between the Pressure, loading or support roller and the winding roll is assigned.
  • the damping arrangement can be arranged according to the invention in at least two alternatives. Either the damping device between the bearing of the pressure roller on the underside of the traverse and the traverse itself is arranged, or the pressure roller is pivotally mounted together with its bearing support via a bearing relative to the crossbar, so that the vibrations between the bearing and the traverse by an in the traverse mounted and and the bearing receiving actuated and thus the pressure roller pivoting damping device are attenuated.
  • a winding device formed by a twin-winder winding machine has two support rollers 1, 2 (Fig. 1), at least one of which is driven.
  • the support rollers 1, 2 form a roller bed, in which several adjacent bobbins 3 rest during winding on the support rollers 1, 2.
  • a longitudinal cutting device (not shown), a material web, in particular a paper or board web, is cut into a plurality of individual webs before winding, which are then passed through the gap between the support rolls 1, 2 or laterally around the jacket of one of the two support rolls 1, 2 are fed into the roll bed, where they are wound up in aligned rows of sleeves 4.
  • the winding rollers 3 is a loading or pressure roller 5 or a plurality of juxtaposed pressure roller segments. 5 stored.
  • the pressure roller segments 5 extend over the entire width of all adjacent bobbins 3 and press the bobbins 3 in the winding bed.
  • the pressure rollers 5 are rotatably mounted in pivot arms 6. These are in turn pivotally mounted about a rotation axis 7 in a machine stand or base 8, which also carries the bearings of the support rollers 1, 2.
  • the pivot arms 6 are pivotable. About (not shown) facilities for force or position control, the cylinder 9 and / or the pivot arms 6 are mounted even in the base 8.
  • Each of the pressure rollers 5 is mounted between the pivot arms 6 on a cross member 10 via a damping device 11 or a plurality of damping devices 11 (FIG. 2).
  • the damping device 11 has a hydraulic cylinder 13, which is subdivided by a piston 14 into a first pressure chamber 15 and a second pressure chamber 16.
  • the piston 14 is connected via a piston rod 17 with a bearing receptacle 18 for the pressure roller 5.
  • a second piston rod 19 is arranged, which has the same diameter as the first piston rod 17.
  • the second piston rod 19 is guided to a blind bore 20 on an end face 21 of the cylinder 13, which faces the traverse 10.
  • the two pressure application surfaces on the piston 14 are the same size.
  • the two pressure chambers 15, 16 are sealed by seals 22, 23, 24 under each other or to the outside.
  • a connecting path 25 connects the two pressure chambers 15, 16.
  • a throttle 26 is arranged in the connecting path 25.
  • a switching valve 27 is provided with an operable by a control or regulating unit according to the desired attenuation input 28.
  • a pressure compensating throttle 29 is arranged, whose flow resistance is substantially greater than the flow resistance of the throttle 26. The pressure compensating throttle 29 allows only a small portion of the hydraulic fluid, which is displaced from the pressure chamber 15 to the pressure chamber 16 or vice versa.
  • Both pressure chambers 15, 16 are connected to a circulation device 30 which is equipped with a pump 31.
  • the pump 31 removes hydraulic fluid from a tank 32 and pumps the hydraulic fluid through the two pressure chambers 15, 16 back into the tank 32.
  • a tempering device 33 is provided, through which the viscosity of the hydraulic fluid through Temperature change can be influenced.
  • the two pressure chambers 15 and 16 via the open switching valve 27 and the throttle 26 are interconnected.
  • the hydraulic fluid is pumped back and forth via the throttle 26 between the two pressure chambers 15, 16, whereby friction energy is generated. The resulting heat is removed from the vibration process, whereby the vibrations are damped.
  • the pressure roller 5 is movable either via a bearing eye 34 in the direction of the piston rod 17 relative to the traverse 10, as shown in Fig. 2, or alternatively, a receptacle 35 via a bearing 36 relative to the crossbar 10 is pivotable.
  • the damping device 11 is again mounted in the traverse 10, but carries out a vibration movement of the receptacle 35 together with the pressure roller 5 mounted therein.
