Definitions

  • the present invention relates to a roller arrangement, in particular a corrugating roller arrangement for corrugating a Material web, for example made of paper or cardboard.
  • Corrugated rollers provided with corrugated profiling are used to a material web made of paper or cardboard, for example permanently deformable and corrugated.
  • the interacting corrugated rollers are used very high pressures. That's why it happens especially for corrugated rollers with long profiled roller bodies, which are each rotatably supported at their roller ends are to a deflection, so that the pressure in the area the interacting profile sections of the two corrugated rollers become uneven over the length of the corrugated rollers can.
  • a corrugated roller has the disadvantage that that of the roller inherent crowning only on a very specific one the crowning coordinated contact pressure for one over the Roll length ensures even contact pressure. Will the contact pressure enlarged or reduced, the crowning leads to an uneven pressure distribution over the Roll length and thus unsatisfactory work results, with the result that either the material web to be processed in the external pressurized Edge areas of the corrugated roller is destroyed or that it is in the edge areas is only insufficiently deformed.
  • Web width of the material web to be processed Another factor affecting the work result when used of such a roller arrangement is determined Web width of the material web to be processed. So is with wider material webs, i.e. with greater utilization of the Length of the profiled roller section, usually one greater contact pressure is required than with a smaller one Material web width and thus less utilization of the Length of the profiled corrugated roller. For example, you choose with a small web width of the material web to be processed too high contact pressure, this can on the one hand lead to Destruction of the material web in its outer areas and on the other hand result in the marginal areas the rollers, which are not covered by the material web will touch each other.
  • a roller arrangement in particular Corrugating roller arrangement for corrugating a material web, for example made of paper or cardboard, this roller arrangement executed with at least one around a first axis of rotation rotatably mounted first roller with a profiled Surface, at least one mounted around a second axis of rotation second roller with a surface, which with a complementary profiling corresponding to the profiling of the first roller is provided, pressing means for Pressing the first roller and / or the second roller onto one another to, wherein in at least one axial edge region first or / and the second roller rolling on each other during operation Slings are provided, through which a Minimum distance between the profiled Surface of the first roller and the one with the complementary profiling provided surface of the second roller is.
  • Slings can thus be prevented from the two interacting rollers when adjusting the contact pressure be brought into a relative position to each other, in which is an "interference" of the rollers at least in their Edge area occurs, which occurs during operation, i.e. with rotating, intermeshing rollers, a mutual contact and destruction of the surface of the corrugated rollers in would result in this edge area.
  • slings directly to the Rollers ensure that they are sufficiently large Distance between the profiled surface and that with the Complementary profiling provided surface of the rollers is guaranteed so that damage to the machined Material web can be prevented.
  • a simple embodiment of the roller arrangement according to the invention arises, for example, when the slings on an adjacent one with the profiling or Complementary profiling provided trained surface unprofiled roller section are formed.
  • the End sections can be from trunnions or from roller sections be formed, which has an outer diameter have, which is smaller than the maximum outer diameter of the profiled roller sections and larger than the outer diameter the bearing journal is.
  • the non-profiled roller section has a smaller outside diameter than the outside diameter one that is profiled or with complementary profiling provided surface of the first or second roller enveloping circle in cross-section. This allows an undesirable interaction between slings and profiled or with complementary profiling Prevent the surface of one of the rollers.
  • the sling means at least one on a roller of first roller or second roller arranged stop ring include, which over its outer peripheral surface with a corresponding contact surface on the other roller of first roller or second roller in mutual contact stands or can be brought into mutual investment, so that the Stop ring with rotating rollers on a corresponding one Stop ring of the other roller or directly rolls on the other roller.
  • the corresponding contact surface on the each other roll of first and second roll of one Outer peripheral surface of one of the other roller from the first and second roller arranged further stop ring is formed.
  • a sufficiently good and even pressure distribution over the entire roller length between the profiled surface the first roller and the one with complementary profiling provided surface of the second roller to ensure can be further provided according to the invention that in axial direction on both sides of the with profiling or counter-profiling provided surface of the first roller or / and the second roller slings are provided.
  • the respective stop ring with the associated one Roll can be provided that this integrally the roller is formed.
  • the stop ring is attached separately to the roller is, preferably by screwing or welding. The separate attachment of the stop ring on the Roller finds existing ones especially when retrofitting Roller arrangement application.
  • the profiling of the respective rollers can be designed as desired his. Such roller arrangements are preferred used in corrugated cardboard manufacture where there is corrugation the material web to be processed is to be reached. Therefore can be provided according to the invention that the profiling or / and the complementary profiling of a corrugation is formed. For sufficiently good work results in particular when processing the material web when the rolls are designed as corrugated rolls one Corrugated cardboard machine, be provided that the minimum distance between the profiled surface of the first roller and the one with the complementary profile Surface of the second roller is smaller than that Thickness of the material web to be processed.
  • the minimum distance between the two surfaces ensures that the material web is pinched between the rollers, which results in a sufficiently good deformation, in particular Corrugation that results in the material web to be processed.
  • Material web thicknesses can also be provided according to the invention be the minimum distance in the range of 0.01 mm to 0.30 mm, preferably in the range from 0.02 mm to 0.20 mm, most preferably in the range of 0.03 mm to 0.10 mm lies.
  • the first or / and the second roller at least in its profiled surface area with a coating, preferably made of tungsten carbide or made of chrome.
  • the invention further relates to a method for retrofitting a roller assembly with slings, comprising the Step attaching the sling, especially with the Lifting device features of the type described above at least one roller of the roller arrangement such that the Sling a minimum distance between a surface the first roller and a surface of the second roller determine.
  • the invention further relates to a material processing machine, especially corrugated cardboard machine equipped with a Roller arrangement of the type described above.
  • FIG. 1 is a corrugated roller arrangement according to the invention generally designated 10.
  • the corrugating roller arrangement 10 comprises a first corrugating roller 12 and a second corrugating roller 14.
  • the first corrugating roller comprises one with one Surface profiling 16, which is in the form of a corrugation is formed, provided roller body 18.
  • a stop ring 20, 22 At both ends of the roller body 18 is a stop ring 20, 22 in arranged in the immediate vicinity.
  • the first corrugated roller comprises 12 journals 24, 26, which in corresponding bearing arrangements 28, 30 for rotatable mounting of the first corrugating roller 12 about its axis of rotation A are included.
