Definitions

  • the invention relates to a Doppeltragwalzenroller according to the preamble of claim 1.
  • Such a double carrier roller is known from EP 0 640 544 B1.
  • the winding station consists on the one hand of the drivable, mutually parallel support rollers and on the other axis displacement means for axially parallel displacement of the second support roller seen in the web running direction with respect to the axis of the first carrier roll seen in the web running direction and lowering the second support roller depending on the increasing diameter of the webs to be produced.
  • the support rollers basically have a different diameter, and their axes are fundamentally different during the winding high horizontal planes, wherein the axis of the second support roller is located during the Wickeins higher than the axis of the first support roller.
  • the pivotable second support roller allows a shift in the distribution of forces with increasing winding diameter towards the second support roller, which can be influenced during the winding process on the winding hardness, which is otherwise determined essentially by the support load on the first support roller.
  • This displacement process can only be used in geometrically narrow limits.
  • a further disadvantage is that the unevenness of the web to be wound, which influences the winding quality, does not find sufficient consideration in terms of length, width and thickness.
  • a Doppeltragwalzenroller is known in which the first carrier roll in the direction of web travel relative to the second support roller during the winding process is lowered lowered.
  • a per se known loading roller is fixed relative to a movable approximately parallel to the support rollers over the entire width of the machine traverse.
  • the traverse together with the loading roller is liftable in a conventional manner by means of pivotally mounted on the machine frame about a pivot axis support arms and acting on the support arms drive means in response to the change in diameter of the roll to be wound and lowered again for a new winding process.
  • the traverse is pivotable about a support roller parallel first axis, and a hinged to the traverse around a support roller parallel second link causes a compulsory pivoting of the traverse with the loading roller about the first axis when the crossbar with the loading roller in adaptation to the increasing roll diameter is raised, so that changes the direction of action of the loading roller on the roll.
  • the load distribution of the loading roller on the first and the second carrier roll can be with increasing roll diameter in the sense of achieving to change an optimized winding structure.
  • the center point curve of the loading roller describes a comparatively flat basic movement line.
  • the object of the invention is therefore to provide a Doppeltragwalzenroller for winding cut fed winding material on several hubs with two paraxial support rollers to improve the winding quality.
  • a Doppeltragwalzenroller in which the adjustment of the at least one support roller for controlling the Auflagelastverrtie on the two support rollers is forcibly transmitted through the rollers with increasing roller diameter on the guide for laterally fixing the plurality of hubs.
  • the leadership of the roll inclination follows an adjustment mechanism, which is dependent on a displacement of the at least one adjustable support roller. The roll quality is thereby increased because the support on the adjustable support roller is optimized.
  • a load roller applied from above with changing forces supports the winding process.
  • the loading roller ensures in the initial phase of the winding for the necessary bearing force.
  • the load roller increasingly assumes fixing and damping tasks.
  • the loading roller is mechanically positively guided, so that it can load exactly in the bisector at each time of the winding process. With a lowering or raising of the at least one support roller and with this movement mechanically tracked load roller can be disturbed as quickly as possible without speed reduction and thus without loss of production in the shortest possible time a vibration. Vibrations caused by discontinuities of a paper roll can thus be avoided.
  • at least one oscillation amplitude of winding vibrations is detected or detected.
  • the vibration system can be detuned by deliberately raising or lowering the at least one adjustable support roller.
  • the natural frequency range of the construction can be influenced to a small extent and, on the other hand, the amplitudes and phase angles of the vibrations can be permanently changed. As a result, a swing can be prevented already in the development phase. It is essential that the production speed can be kept constant. This results in a significantly higher productivity than in the usual in the prior art speed reduction to change the excitation frequency.
  • the influence on the oscillation amplitude is substantially influenced, which has a significant influence especially in the case of small rolls in the diameter range of about 300 to 1200 mm.
  • the inventors of the present invention have recognized that the irregularities of the web to be wound in length, width and / or thickness add up during the winding process and are capable of causing the rollers themselves as well as the construction of the rolling machine to vibrate, and that these vibrations are causally responsible for negative effects on the winding quality and for an increased noise emission. Also mechanical damage can be caused.
  • According to the vibration system and its winding vibrations are disturbed by an adjustment of at least one support roller.
  • the control of the adjustment of the at least one adjustable carrier roll can be initiated.
  • the extent of the displacement of the at least one support roller is determined by the predefinable limit values of a vibration amplitude of the winding vibrations.
  • 1a to 1c schematically show a Doppeltragwalzenroller as a schematic representation in the frontal view of the support rollers with the at least one adjustable support roller in different displacement positions according to a first embodiment
  • FIGS. 2a to 2c show schematically a double roller carrier roller as a schematic representation in the frontal view of the support rollers with the at least one adjustable support roller in different displacement positions according to a second embodiment
  • FIG. 3 schematically shows a perspective view of the double carrier roller according to FIGS. 2a to 2c from a web inlet side
  • FIGS. 2a to 2c shows schematically a perspective view of the double carrier roller according to FIGS. 2a to 2c from a web outlet side
