Definitions

  • the invention relates to a roller arrangement with two rollers forming a nip and support connections arranged between the rollers, the rollers each having a carrier, the roller jacket of at least one roller arranged rotatably around the fixed carrier, mounted thereon by means of at least one support element and to the carrier along a printing plane the roller is displaceable and the support parts receiving one end of the carrier and arranged at the same end of the rollers are connected to one another via at least one elongate connecting part running along the pressure plane.
  • roller connections between rollers are already known and are used in roller arrangements which are used for the production and processing of material webs.
  • the support parts receiving one end of the carrier of the roller are connected to one another via U-shaped clamps screwed thereon. Because of the surface pressures and bending moments that occur, these and the support parts must be large and therefore heavy-weighted. This also involves a considerable amount of time for the loosening of these connections.
  • the invention has for its object to provide a support connection that a compact design and a quick change of roller, felt, cloth or the like. allowed.
  • the support parts receiving one end of the carrier are positively connected via at least one elongate connecting part running along the pressure plane, which has thickened portions at both ends and is accommodated in corresponding recesses in the support parts.
  • a secure support connection between two rollers is obtained when the roller shell at least one roller to the fixed support along one Printing plane of the roller is displaceable.
  • the thickening of the connecting parts can have, for example, a prismatic, trapezoidal or semicircular cross section. It is advantageous if the thickenings have the cross-sectional shape of a semicircle, the straight boundary of which is directed away from the connecting part. This leads to a design simplification of the recess, which therefore only consists of the elongated section and an adjoining bore.
  • the connecting parts which are mainly subjected to tensile forces, they should extend from the outside of the support parts to at least 50% of the support part thickness towards the roller. Furthermore, it is favorable to use two or more connecting parts between the support parts and to arrange them symmetrically to the pressure plane.
  • transverse forces that may occur should be absorbed by appropriate shaping of the contacting connecting surfaces of the support parts. This is also possible by embedding an intermediate piece between the two support parts. This would have the additional advantage that when the same is removed, the change of the roll shell, sieve, felt or the like. is made possible or facilitated.
  • a variant consists in that the support parts of the lower roller each rest on a stationary stand which simultaneously guides the support parts.
  • the support connections are released simply by relieving the pressure on the support elements that press the roll shell of a roll in the direction of the counter roll. After this relaxation of the positive connection, the connecting parts can be easily removed and the support parts can be lifted off using appropriate lifting devices.
  • the support parts of the upper roller are each carried by a stationary stand.
  • the support parts of the lower roller If a loosening of the connections is necessary, this is also done by relieving the load on the support elements, but afterwards the position of the lower roller has to be raised and fixed somewhat by appropriate external auxiliary devices to further relax the connection. This arrangement is particularly advantageous when the access options to the lower roller have to be improved.
  • two rollers 1 and 2 form a nip for processing a material web 3, the roller jacket 13 of the upper roller 1 being rotatably arranged around a fixed support 14, supported thereon by means of a plurality of support elements 17 and becoming a support 14 along the Printing plane of the roller 1 is displaceable.
  • support elements 17 are known for example from CH-PS 541 088. These roller arrangements are often used to smooth paper webs.
  • the support parts 5 and 6, each receiving one end of the supports 14 and 16, are each via two elongate connecting parts 7 running along the pressure plane and extending over the entire thickness of the support part, which have thickenings 8 at both ends and in corresponding recesses 9 of the support parts 5 and 6 are housed pull-out parallel to the roller axis, positively connected.
  • the support parts 6 of the lower roller 2 each rest on a stationary stand 12, which supports both support parts 5 and 6 at the same time laterally and thus absorbs forces transversely to the pressure plane.
  • the cantilever carrier 18 should have a transport device 20 for installing and removing the lower roll 2.
  • connections are made in such a way that the lower roller 2 is held in a predetermined position via its carrier 16 and auxiliary devices acting thereon and then the support parts 5 of the upper roller 1 are placed on the stand 11. After inserting the connecting parts 7 into the recesses 9, this is done Tensioning the connections over the displacement of the roll shell 15 by means of the support elements 17 along the pressure plane towards the roll 1.
  • the change of the lower roll shell 15 also presupposes the loosening of the support connections on the driver's side and the intermediate pieces 22 that are present laterally between the stand 11 and the lower support part 6. If, as shown in FIG. 2, the lower support part 6 is smaller than the roller jacket 15, there is no need to remove it.
  • the roll shell 15 can now be changed via the known devices, the end of the carrier 16 of the lower roll 2 on the driver's side having to be held in position.
