Definitions

  • the invention relates to a carrier roll winding machine for winding a material web, in particular a paper or board web, on at least one winding tube to at least one winding roll which is located in a winding bed formed by two support rollers, with a pressing the at least one winding roll in the winding bed Loading roller, wherein the center of the loading roller during the winding process at least temporarily, in particular at the end of the winding process, is located on a line perpendicular to a perpendicular bisector line, wherein the perpendicular bisector perpendicular to a connecting line between the centers of the support rollers, and wherein the loading roller a inside the Loading roller or arranged on the leadership of the loading roller damping device comprises.
  • Material webs must be wound up into shipping or finishing rolls before they can be shipped.
  • this winding cores are usually used, which preferably consist of cardboard.
  • the finished rolls are produced in that of so-called mother rolls or Volltambouren that are produced at the output of a paper or coater or a calendar, the web unwound, cut in the longitudinal direction and then wound on each winding tubes.
  • These cores lie in a winding bed formed by two support rollers of a double carrier roll winding machine.
  • a double carrier roll winding machine as for example from the DE 200 13 319 U1 or the EP 0 792 245 B1 is known, according to the number of generated from the original material web by longitudinal cuts individual webs several cores next to each other in the winding bed, even if subsequently, for the sake of simplicity, only a single winding tube is always addressed in conjunction with a wound on her web winding.
  • a carrier roll winding machine in which the winding roll is pressed by a vertically arranged above the winding roll load roller in the winding bed.
  • the load roller exerts a minimum load of 0.5 kN / m on the reel during the entire winding process.
  • the loading roller serves to achieve a desired winding hardness during winding.
  • the winding roll should namely be wound harder inside than in the area of the circumference. In order to achieve sufficient winding hardness even at the beginning of the winding process, despite the initially low net weight of the wound only with a few layers of the web winding tube, the loading roller presses the winding roller with a predetermined force into the winding bed.
  • the load roller can be fixed either on a rocker or on a linear guide; the function of the loading roller is independent of whether it is guided on a straight line or a circular path.
  • the invention can also be realized independently of whether the centers of the support rollers lie on a horizontal connecting line or whether they have a relation to the horizontal inclined connecting line.
  • the loading roller is inclined with respect to a passing through the center of the winding roll, the connecting line at right angles intersecting perpendicular bisector, at least during most of the winding time, ie at least from reaching a predetermined winding diameter.
  • An advantage is an arrangement in which the line on which the center of the loading roller is located is inclined by an angle between 5 and 45 °, in particular by an angle lying between 15 and 30 ° with respect to the mid-perpendicular.
  • this angle is formed at the end of the winding process by the force normal of the loading roller in the direction of the angle and the perpendicular bisector. At the beginning of winding this force standards is advantageously parallel to the perpendicular bisector.
  • damping device (8) comprises a control or a regulating device.
  • control or regulating device may comprise in a particularly preferred manner a measuring transducer for measuring the position of the shaft of the loading roller (5).
  • Particularly suitable is an embodiment of the winding machine in which the spring stiffness of the spring and / or the damping of the damper are variable.
  • springs are used in the form of bending beams or as spiral springs.
  • springs are used in the form of bending beams or as spiral springs.
  • springs are used in the form of bending beams or as spiral springs.
  • mechanical springs and hydraulic or pneumatic solutions come into question.
  • the invention also relates to a method for winding a material web, in particular a paper or board web, in a carrier roll winding machine on at least one winding tube to at least one winding roll, which is located in a winding bed formed by two support rollers, using a loading roller.
  • the method is characterized in that the center point of the loading roller is guided on a line inclined relative to a mid-perpendicular line during the winding and presses against the at least one winding roller, wherein the perpendicular bisector is perpendicular to a connecting line between the centers of the carrier rollers.
  • the support rollers 1, 2 form a roller bed, in which several adjacent winding rollers 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
  • the material web is thus guided in the upper web guide in the double carrier rollers winding machine, ie the material web comes "from below", but runs "from above” in the first Tragwalzennip.
  • a loading roller 5 is mounted, which extends over the entire width of all adjacent bobbins 3 and presses the bobbins 4 in the winding bed.
  • the loading roller 5 is initially arranged perpendicular or substantially perpendicular above the winding rollers 3, since the winding bed due to the large diameter of the support rollers 1, 2 leaves no room for an inclined arrangement of the loading roller 5 relative to the winding rollers 4.
  • the guide line F is inclined to a line perpendicular M to a connecting line V between the midpoints M 1 and M 2 of the support rollers 1 and 2.
  • the loading roller 5 by means of a (here only indicated) linear guide 6 continuously with the increase of the diameter of the winding rollers 3 after led up, so that the loading roller 5 always rests with the desired contact pressure on the winding rollers 3 and suppresses vibrations of the winding rollers 3.
  • the guide line F is inclined with respect to a mid-perpendicular M to a connecting line V between the centers M 1 and M 2 of the support rollers 1 and 2.
  • the loading roller 5 is provided with a damping device 8 (FIG. Fig. 4 ), which is integrated in the guide 6 or the rocker 7, in which the loading roller 6 is mounted on a bearing 9.
  • the damping device 8 comprises an actuator 10, a spring 11, a damping cylinder 12 connected to the spring 11 and a measuring device 13. This generates a signal according to the current position of the loading roller 5, which passes the measuring device 13 to the actuator 10, so that this 5 operates a piston of a hydraulic or pneumatic cylinder according to a deviation between an actual position and a required target position of the loading roller.
  • an electromotive adjusting means such as a pneumatically operated bellows cylinder or a rolling diaphragm can be used to press the loading roller 5 with the desired contact pressure against the winding rollers 3. If the loading roller 5 in turn should vibrate as a result of vibrations of the winding rollers 3, the vibrations are damped by the damping device 8 quickly.
