Definitions

  • the invention relates to a spreader roll for a web-processing machine.
  • Spreader rolls are used in web-processing machines in order to avoid wrinkling or sagging of the material webs when the webs of material are running. Furthermore, spreader rolls are used to allow side by side juxtaposed material webs to diverge laterally. Parallel juxtaposed webs can be generated, for example, by slitting a wide web of material.
  • the spreader rollers known from the prior art usually have a bent and stationary core on which a plurality of independent roller segments are supported by means of roller bearings in order to simulate a curved roller in several sections.
  • the o.g. Spreader rolls are expensive in their construction and maintenance. Furthermore, the o.g. Spreader rolls the curvature not adjustable.
  • the US-A-4,663,809 discloses a roller in which, to compensate for the deflection of the support core, the distance between the roll shell and the support core is adjustable at the roll edge.
  • the DE-U-200 05 499 shows nip rolls with an arrangement for bend correction.
  • the DE-A-199 40 424 further shows a roll with roll core and roll shell, in which the distance between the roll core and shell is adjustable.
  • the invention is based on the idea of creating a spreader roll in which the angle of the deflection as well as the size of the deflection (curvature) can be made independently of the bearing core.
  • a spreader roll for a web-processing machine has a support core with a longitudinal axis.
  • the support core is mounted here at its two longitudinal ends.
  • the generic spreader roller has an elastically bendable outer jacket, which surrounds the support core in its circumferential direction and which extends at least in sections between the two longitudinal ends of the support core.
  • the outer jacket is mounted on the support core on at least one bearing.
  • the outer jacket is mounted on the bearing such that the outer jacket is immovable perpendicular to the longitudinal axis of the support core.
  • the outer jacket is on at least one shift point mounted displaceably perpendicular to the longitudinal axis of the support core, wherein the displacement point is spaced along the longitudinal axis of the support core to the bearing.
  • the curvature of the outer shell is adjustable.
  • the outer sheath between the bearing and the displacement point is at least partially elastically deformable.
  • the outer sheath is formed at least partially elastically deformable.
  • the longitudinal axis of the outer jacket between the bearing and displacement point is curved relative to the longitudinal axis of the support core.
  • the support core of a foam and / or honeycomb core which is at least partially covered by a fiber composite material, constructed.
  • a foam core with almost unlimited possibility of shaping is first created, which is enveloped by a fiber composite sheath. This creates a support core with a high modulus of elasticity and low weight, which can be realized easily and with almost any shape.
  • the outer jacket is preferably formed integrally between the bearing and the displacement point.
  • outer shell is formed by a contiguous portion of material (either made of a single cast or of several material sections) and not by a plurality of non-interconnected material sections.
  • the outer jacket also has a displacement component parallel to the longitudinal axis of the support core. Thereby, the outer shell can be compressed in its longitudinal direction, whereby a different bending line can be obtained.
  • two displacement points are provided, between which the bearing is arranged. This makes it possible to bend the outer sheath on both sides of the camp.
  • the outer shell has a respective displacement point at its two longitudinal ends. If the bearing is preferably provided in the middle region of the longitudinal extension of the outer jacket, the outer jacket can be bent symmetrically relative to the bearing.
  • the outer jacket is rotatably connected to the bearing with the support core, so that the outer shell is rotatably mounted on the support core.
  • the rotatable mounting can be done via rolling or plain bearings.
  • plain bearings are, for example, hydrodynamic or hydrostatic sliding bearings or air bearings conceivable.
  • the o.g. Feature is particularly but not exclusively advantageous if the support core is not rotatable about its longitudinal axis.
  • the outer sheath is rotatably connected to the support core at the first support point.
  • a rigid connection between outer shell and support core is created around a To allow torque transmission between Stauerkem and outer sheath and secure the outer sheath against the Stauerkem against displacement in the longitudinal direction.
  • the non-rotatable connection between Stauerkem and outer jacket is, for example. By gluing or pressing produced.
  • Embodiment is essentially applicable when the Stitzkem is rotatable about its longitudinal axis.
  • a further embodiment of the present invention also provides that at least one support point attached to the outer casing or Stauerkem and arranged in the longitudinal direction between the bearing and displacement point is provided, on which at least the curvature of the outer shell of the support core or the outer shell can be brought into abutment.
  • at least one support point it is possible to influence the curvature or bending line of the outer shell relative to the Stauerkem, as determined by the support point, the minimum distance between the outer shell and Stauerkem upon bending of the outer shell.
  • the rotatable mounting can be done via angle-adjustable rolling or plain bearings.
  • the second support points are arranged in the longitudinal direction on both sides of the bearing and between the two displacement points.
  • the position of the outer jacket relative to the Stauerkem can be accomplished, for example, by two mutually rotatable eccentric discs, which in each case take effect on the arranged at the longitudinal ends displacement points.
  • a moment is induced by the deflection at the displacement points and the non-displaceable mounting of the outer shell on the support core, which deforms the outer shell according to its bending line relative to the support core.
  • Another possibility of displaceable storage consists of slidable in two levels guides, which can each influence the arranged on the longitudinal ends sliding points. But it is also possible to produce the curvature by a linear displacement and then to pivot the curved spreader roll about the longitudinal axis of the Stitzkems.
  • the relative adjustment is accomplished by incorporated in the outer tube piezoelectric elements.
  • the incorporated piezoelectric elements may be formed, for example, in the form of piezo fibers. By applying corresponding electrical voltages, the piezoelectric elements stretch and contract at different points of the outer jacket, whereby the outer jacket bends.
  • the longitudinal axis of the support core is straight.
  • the support core rotates about its own axis as well as that the Stauerkem is not rotatable about its own axis.
  • Another embodiment of the invention further provides that the longitudinal axis of the Stauerkems runs curved.
  • the Stauerkem does not rotate around its own axis and that the rotation of the Outer jacket is realized by rotatable storage in stock.
  • the support core along its longitudinal axis at least partially changing cross-sectional shape ha, in particular at least partially conical.
  • the support core at least partially made of a material having a modulus of elasticity in the range of 10 to 1000GPa, preferably from 50 to 800GPa, more preferably from 100 to 500GPa and a density in the range of 0.5 to 3 g / cm 3 , preferably from 1.0 to 2.0 g / cm 3 , more preferably from 1.3 to 2.0 g / cm 3 is made.
  • Preferred materials for the production of the support core are in combination or alone: plastics and / or metallic material which are produced in the form of foams and / or in the form of honeycombs.
  • the outer shell in its longitudinal direction has a modulus of elasticity in the range from 0.5 to 1000GPa, preferably from 10 to 700GPa, more preferably from 50 to 200GPa, the elastic modulus of the support core being greater than the modulus of elasticity of the outer jacket.
  • a flexible as possible outer jacket is provided in the longitudinal direction.
  • the lower modulus of elasticity in the longitudinal direction of the support core can be achieved, for example, in that, in the case of a fiber composite material, the fibers are oriented essentially in the circumferential direction of the support core.
  • a preferred embodiment of the invention provides that the outer jacket in the radial direction has a modulus of elasticity which is greater than the elastic modulus in the longitudinal direction.
  • the influence of the bending line of the outer shell can be influenced by changing the material thickness of the outer shell, so that different bending lines can be adjusted depending on the requirements of the spreader roll. Accordingly, a preferred development of the invention provides that the outer casing has a material thickness and / or cross-sectional shape which changes at least in sections in its longitudinal direction. Other possibilities for influencing the bending line of the outer shell consist of material orientation and / or by the selected material combination.
  • the outer sheath is preferably produced in combination or solely from a plastic and / or from a metallic material and / or from a fiber composite material.
  • the outer sheath is at least partially covered by a cover.

If the covering material has boundary surfaces in its composition, this is called a discontinuous material composition.
  • cover material which continuously changes its composition in the radial direction from 100% thermoset material to 100% elastomeric material.
