Definitions

  • the invention relates to a roller for a winding machine, in particular for winding paper or cardboard webs, which is intended to rest under pressure on winding rollers during winding, and a winding machine with a roller according to the invention
  • Cardboard webs are known to use winding machines that have one or two driven rollers on which the winding rollers rest or rest during winding.
  • the rollers are called support rollers if they fully support the weight of the overlying winding rollers (DE-A 39 24 612) Weight wholly or partly held by guide heads retracted into the sleeves of the winding rolls and supported on support arms, the rolls are referred to as support rolls (DE-C 31 02 894, DE-C 40 12 979).
  • winding machines contain a so-called pressure roller, which is printed against the contact line between a winding roller and a support roller or support roller against the winding rollers at the start of winding, if the contact pressure resulting from the roller weight is not yet sufficient for the desired winding hardness, and which contributes significantly to the stability of wrapping (DE-C 37 19 093, EP-C 0410093)
  • the line pressure is the contact pressure standardized to the winding roll width, measured in N / m.
  • the carrier roller on the outlet side which is not wrapped around by the web and lowered compared to the carrier roller on the inlet side, has a jacket which is much more deformable than that Jacket of the feed roller on the inlet side.
  • the support roller has an outer layer of rubber, in which chambers are arranged which are connected to the inside of the support body made of steel. Due to the strong deformability, the contact pressure on the support rollers should be limited as much as possible, so that the winding hardness does not increase excessively.
  • the invention has for its object to provide a roller for a winding machine, which enables a winding with lower winding hardness when used as a support or support roller.
  • a pressure roller When used as a pressure roller, it should fluctuations in the uniformity of the winding rolls, the z. B. result from path profile fluctuations, can compensate so as to ensure the uniformity of the contact pressure.
  • FIG. 1 shows a longitudinal section through a support or support roller according to the invention
  • FIG. 2 shows a cross section through the roller from FIG. 1,
  • FIG. 6 shows a roller in which the compressible layer consists of individually wound rings
  • Figures 7 and 8 the mode of action of a support roller according to the invention in comparison to a support roller according to the prior art in a support roller winding machine.
  • Figure 8 is the principle of a support roller winding machine for winding through
  • FIGS. 1 to 6 Longitudinal sections of subdivided paper or cardboard web 1 into winding rolls 2 are shown, in which the roller shown in FIGS. 1 to 6 can be used as a support roller or as a pressure roller.
  • a support roller winding machine contains two driven support rollers 3, 4, on which the winding rollers 2 lie coaxially and aligned when they are being wound up and which thus bear the entire weight of the winding rollers.
  • the paper or cardboard web 1 is preferably guided from below, the infeed-side support roller 4 partially looping through the gap between the support rollers 3, 4 and runs in the nip between the infeed-side support roller 4 and the winding rolls 2.
  • One or both support rollers 3, 4 of the support roller winding machine are designed as a roller according to the invention.
  • the roller according to the invention is preferably used as an outlet-side support roller 3 which is arranged opposite the inlet-side support roller 4 in such a way that its contact line with the winding roller (nip 5) is at the same height or lower than the contact line between the other winding roller 4 and the winding roller runs.
  • the support roller 3 thus carries the same or greater proportion of the weight of the winding rollers 2.
  • the upstream support roller 4 can also be designed as a roller according to the invention
  • a pressure roller 6 which extends over the working width of the winding machine, ie the axial length of the support rollers 3, 4, and which at the start of the winding presses the winding rollers 2 against the support rollers 3, 4 if the winding roller weight for the desired winding hardness is not yet sufficient
  • FIG. 1 to 6 the structure of a roller according to the invention when used as a support or support roller 3 is shown in more detail.
  • a support or support roller 3 As a support or support roller 3, it has an axial length which corresponds to the maximum width of the paper or cardboard web 1 to be processed, which can be up to 10 m, their diameter is between 500 mm and 1500 mm.
  • the support or support roller 3 according to the invention consists of a hollow cylindrical support body 7 made of a solid material, in particular steel, which is designed to be sufficiently stable to prevent bending to be able to support the forces acting on or against the winding rollers 2 on both end faces of the supporting body 7, shaft journals 8 are fastened, with which the roller 3 is mounted in the frame of the winding machine.
  • a shaft journal 8 of each carrier or support roller 3 is connected to a rotary drive , with which the roller 3 is rotated about its longitudinal axis, around the overlying or adjacent winding rollers 2 for winding to turn
  • a layer 9 of a cellular, a plurality of pores filled with a gas, in particular air, and therefore compressible plastic material is applied, which has a compression module K of less than 10 MPa. It is important that a large Number of relatively small pores is uniformly distributed over the volume of layer 9.
  • the pore size is preferably less than 5 mm, and a pore size between 0.05 mm and 1 mm has proven to be particularly advantageous.
  • the pores in layer 9 are preferably partially open - that is interconnected - partially self-contained The proportion of open pores is 30% to 70%, preferably approx. 50%.
  • a cellular elastomer, in particular polyurethane, produced by foaming and having a compression modulus K of 1 MPa to 5 MPa is preferably used for the layer 9.
  • the radially measured thickness of layer 9 is at least 10 mm, preferably between 10 mm and 40 mm, in the example approximately 25 mm.
  • the density of the material of the layer 9 with the pores is less than 800 kg / m 3 , preferably between 350 and 650 kg / m 3 .
  • the layer 9 has a hardness between 15 and 60 measured according to Shore-A. The roller is thus relatively soft on its outer surface in order to form a relatively wide nip when a winding roll is in contact.
  • FIGS. 3 to 5 show different possibilities for arranging the compressible layer 9 on the support body 7:
  • the layer 9 of compressible material preferably a cellular elastomer, on the outer lateral surface of the support body 7.
  • the thickness of the layer 9 is 10 mm to 40 mm.
  • a plurality of circumferential grooves are worked into the outer surface of the layer 9 at a distance from one another, if the wrapping of air in a winding roll 2 is to be avoided or excessive noise during winding is to be reduced.
  • Non-slip binding can e.g. B. can be achieved by vulcanization.
  • a further elastic layer is attached to the outside of the compressible layer 9, which is grooved if necessary.
  • FIG. 5 shows an embodiment with circumferential grooves 12 in a wear-resistant outer layer 11.
  • the compressible layer 9 is fastened directly on the support body 7 without an intermediate layer.
  • Figure 6 shows the preferred embodiment of a support or support roller according to the invention, in which the compressible layer 9 consists of individual rings 13.
  • the rings 13 with a width in the axial direction of the roller of 50 mm to 500 mm are either immediately successive or with such a small distance from one another arranged that the gap between two rings 13 does not cause any marks on the winding rolls 2 If there is a distance between the rings 13, this is preferably 5 mm to 30 mm.
  • Rings 13 are preferably used which are larger by the desired thickness of the layer 9 and have a slightly smaller inner diameter than the outer diameter of the support body 7. The rings 13 are pushed onto the support body 7 with an inner diameter widened by expansion, so that they then sit under tension on the support body 7.
  • a sufficiently firm fit can also be achieved, for example, by fastening the rings 13 to the support body 7 in a form-fitting manner or by gluing or jamming.
  • the rings 13 are arranged in parallel on the support body 7 in such a way that their end faces are either perpendicular or oblique to the roller axis
  • the rings 13 form a quasi-screw joint with the advantage that a gap between the rings 13 permanently varies its axial position during rotation, and so markings on an adjacent winding roll are avoided
  • the roller then consists of a supporting body 7 with a compressible layer 9 made of a band-shaped material applied in the form of a screw limestone
  • FIG. 7 shows a carrier roller winding machine according to the prior art, in which the outlet-side carrier roller 14 has an elastic, but incompressible jacket surface.
  • the support roller 14 deforms elastically in the nip 5.
  • the evasive elastic material forms at both ends of the nip 5 beads 15 which protrude radially from the rest of the outer surface.
  • This acceleration increases the so-called nip-induced elongation of the outer layer, ie the winding hardness increases.
  • the positive effect intended by the elastic outer layer, by widening the nip 5 to lower the contact pressure and thus the winding hardness dependent on the contact pressure, is decisively reduced and can even be reversed.
  • FIG. 8 shows the conditions when winding with a carrier roller winding machine using a carrier roller 3 according to the invention:
  • the compressible layer 9 20 is compressed under the support weight of the winding rolls 2, its volume is reduced.
  • the result is a wide nip 5 without beads or with negligible beads on both ends.
  • the contact pressure on the support roller 3 drops due to the widened nip 5, and the nip-induced elongation of the outermost layer on the winding roll 2 is reduced.
  • it can be wound with 5 lower winding hardness per meter of roll length with the same coating weight. This enables the winding of
  • roller according to the invention is not limited to use as a support roller in support roller winding machines, but it can also be advantageous for others
  • Winding machine types can be used as a contact roller on the winding rollers under pressure in order to produce winding rollers with large diameters and high quality at high production speeds.
  • their use as a backup roller in so-called backup roller winding machines is advantageous, in which 5 winding stations are arranged on both sides of a central backup roller in two winding lines, to which the individual webs are alternately fed.
  • Each winding roll is - such as.
  • the roller When used as a pressure roller, which is given the reference number 6 in FIGS. 7 and 8, the roller is constructed in accordance with FIGS. 1 to 6 in the manner described above for small axial lengths. Since the pressure rollers are freely rotatable and not driven, no rotary drive acts on the shaft journal 8. For pressure rollers with a large axial length, as z. B. are used in support roller winding machines l o, the pressure roller is preferably built up from individually rotatably mounted segments in order to enable the individual segments to rotate independently. Printing rollers have diameters that are in the range from 200 to 400 mm, that is, usually smaller diameters than support or support rollers.
