Definitions

  • the invention relates to a winding device with a winding roll for sheet material, in particular Paper, and one of a deflection of the Supporting device counteracting from below without contact, which a compressed air cushion between the support device and the winding roll, wherein the support device at least one support plate with one of the Contour of the underside of the winding roll largely adapted Has top, in which at least one Compressed air outlet opening is formed, the Compressed air through a gap between the winding roll and the support plate can emerge and the effective Flat of the support plate radially to the winding roll in Depending on the winding diameter is adjustable and largely adapted to the winding roll contour remains.
  • winding and unwinding a sheet material especially paper
  • both devices cause an insufficient Protection of the winding surface, because both the support rollers as well as the moving belt practice a mechanical Influence on the web to be wound up, namely in the case of the winding device with air cushion space, because the seal on the two axial ends of the Air cushion space due to the changing winding radius, which, for example, grow from 500 mm to 3000 mm can, is difficult.
  • the winding roll has a length that extends over its length, open at the top and pressurized with compressed air Air box height adjustable and swiveling to arrange.
  • On its front upper edges is the Air box with the curvature of the winding roll by means of Air box arranged adjusting elements adaptable sealing strips and on one longitudinal upper edge also with a sealing strip and on the other longitudinal top edge with a along this Provide upper edge extending spacer roller.
  • the Sealing strips are by the when swiveling the Air box on the winding roll on this abutting spacer roll at a distance corresponding to a desired one Air gap held by the winding roll to a friction between the winding roller and the sealing strips to avoid.
  • 8 is another spacer roll along the other long side Upper edge of the air box stored. Such Furnishing is because of its numerous components complex and does not work without contact.
  • a generic winding device is from DE-A-32 25 872 or US-A-3 920 136 known to the preamble of claim 1 corresponds.
  • the altitude is the axis of rotation of the winding roll depending on Although the winding roll diameter is shown differently, but no height-adjustable storage and drive device disclosed. If the axis of rotation is not is adjustable in height, the pressure of the compressed air cushion accordingly free floating arrangement the winding roll from the outset the greatest weight the winding roll corresponding to the largest winding roll diameter match if he doesn't match that Winding roll diameter is regulated, which is also is not disclosed. This requires considerable energy required to generate the compressed air while at the same time with a small winding roll diameter and correspondingly low winding roll weight and larger Air gap Excessive compressed air escapes unused.
  • the support plate consists of a flexible steel band, which with Plastic is coated and only in the middle can be raised or lowered between two carrying rollers can by placing one of the two support rollers around which the Longitudinal sections of the steel strip partially wrapped around are rotated accordingly by means of a cylinder becomes. An automatic adjustment depending the roll diameter is not mentioned here.
  • the winding roll is floating on the compressed air cushion stored and the support plate not automatically dependent adjustable from the winding diameter.
  • the maximum weight of the winding roll corresponding air pressure with correspondingly high compressed air losses required, especially if the Support plate under the front edges of the winding roll in each case has a partially circulating survey that does not, however, extend in the longitudinal direction of the winding roll, so that the compressed air in the circumferential direction of the Winding roll through a relatively large air gap can escape, however, the rotating winding roller until the formation of high air pressure on the Surveys are frictionless.
  • the invention has for its object a winding device of the generic type to specify the the web more reliable gentle support of the winding roll within the web width with less compressed air losses enables.
  • the object is achieved in that the Winding roller driven on a fixed axis of rotation and the entire support plate radially to the winding roll in Automatically adjusted depending on the winding diameter becomes.
  • the support plate can be designed to be flexible.
  • the support plate can therefore be proportionate extend large wrap angle of the winding roll and yet easily under the power of Servomotors that are near their axially parallel attack edges extending to the winding roll, against bend the force of the compressed air so that the radius of curvature their top largely the respective Radius of curvature of the winding or winding on the Winding roll is adjusted.
  • the support plate on her Underside near each of its axial longitudinal edges each has a downwardly projecting projection and an actuator between the ends of the protrusions is articulated through which on those ends a force can be exerted that such a bending the support plate causes the radius of curvature of their Top of the current radius of the wrap corresponds to the winding roll.
  • a web 1 here a paper web, is wound on a stationary, driven winding roll 2 and thereby horizontally by a contact or contact roll 3 with a force F k on the winding roll 2 or the winding 4 ( or the winding).
  • F k force on the winding roll 2 or the winding 4 ( or the winding).
  • the winding roller 2 and the winding 4 bend more, the different deflection differences ⁇ F between the contact roller 3 and the winding roller 2 or winding 4 leading to an uneven contact pressure curve q k over the web width with which Consequence that crepe folds and bursts occur in the edge areas of the winding 4.
  • a support device with a flexible support plate 5 and pneumatic or hydraulic servomotors 6 in the form of piston-cylinder arrangements is provided.
  • the support plate 5 has a top surface largely adapted to the contour of the underside of the winding roll 2, in which three compressed air outlet openings 7, to which compressed air is supplied through the support plate 5 from a compressed air source, not shown, are formed.
  • the compressed air can escape through gaps 8 between the winding roller 2 and the support plate 5 and counteracts the force F r of the servomotors 6 acting in the vicinity of the longitudinal edges of the support plate 5 parallel to the winding roller 2.
  • the compressed air forms an air cushion in the gap 8 between the support plate 5 and the winding roll 2, the top of the support plate 5, due to the bending elasticity of the support plate 5, the contour of the winding 4 with increasing diameter of the winding 4 from the smallest winding radius R min corresponds to the radius of the winding roll 2, largely adapts to the largest radius of curvature R max of the winding 4.
  • the support plate 5 is shifted downwards by the servomotors 6 in synchronism with the increase in the diameter of the winding 4, as is shown by the lower position of the support plate 5 in FIG. 2.
  • each support plate 5 has only one compressed air outlet opening 7 and is subjected to the force F r individually by one of the two servomotors 6, the direction of action of the forces F r , in contrast to that of the forces F r in the embodiment according to FIG. 2, in the Attacks the center of the respective support plate 5 and is directed exactly radially to the central axis of the winding roll 2.
  • the servomotors 6 on the one hand with its piston rod on the support plate 5 and articulated on the other hand on a stationary frame.
  • the winding radius also acts as a reference variable for the adjustment of the support plate (s) 5 by the Servomotors 6 in a position control device.
  • FIG. 6 it is possible to provide a modification according to FIG. 6 in which only one support plate 5 according to FIG. 2 and two support plates 5 according to FIG. 3, in which the single or each support plate 5 on its underside in the vicinity of each of them Axial longitudinal edges each have a downwardly projecting projection 9 and a servomotor 10 is articulated between the ends of the projections 9, by which a tangential force F t can be exerted on those ends, which causes such a bending of the support plate 5 that the radius of curvature of their Top corresponds to the current radius R of the winding 4 on the winding roll 2.
