Definitions

  • the invention relates to a winding device with a winding roll for web-like material, in particular paper, with a support device which counteracts a deflection of the winding roll from below and which generates a compressed air cushion between the support device and the winding roll.
  • both devices cause inadequate protection of the winding surface, because both the support rollers and the moving belt exert a mechanical influence on the web to be wound, namely in the winding device with air cushion space because the seal at the two axial ends of the air cushion space because of the changing winding radius, which can for example increase from 500 mm to 3000 mm, is difficult.
  • FIG. 7 it is known to arrange a height-adjustable and pivotable air box below the winding roll, which extends over its length and is open at the top and pressurized with compressed air.
  • the air box On its front upper edges, the air box is provided with sealing strips that can be adapted by means of adjusting elements arranged in the air box, and on its one longitudinal upper edge also with a sealing strip and on the other longitudinal upper edge with a spacer roller that extends along this upper edge.
  • the sealing strips are held at a distance corresponding to a desired air gap from the winding roller by the spacing roller which bears against the winding roller when the air box is pivoted against it to avoid friction between the winding roller and the sealing strips.
  • a further spacer roller is mounted along the other longitudinal top edge of the air box.
  • the object of the invention is to provide a winding device of the type mentioned at the outset, which enables the web to be supported more reliably and gently within the web width.
  • the support device has at least one support plate with a top surface largely adapted to the contour of the underside of the winding roll, in which at least one compressed air outlet opening is formed, that the compressed air can escape through a gap between the winding roll and the support plate, and in that the support plate is automatically adjustable radially to the winding roll as a function of the winding diameter and adapts to the winding roll contour.
  • the support plate can be designed to be flexible.
  • the support plate can therefore extend over a relatively large wrap angle of the winding roll and yet bend easily against the force of the compressed air so that the radius of curvature of its upper side largely under the force of servomotors which act in the vicinity of their edges which extend axially parallel to the winding roll is adapted to the respective radius of curvature of the winding or the winding on the winding roll.
  • the support plate prefferably has a downwardly projecting projection on its underside near each of its axial longitudinal edges and between the ends of the projections an actuator is articulated, by which a force can be exerted on those ends which causes the support plate to bend such that the radius of curvature of its top corresponds to the instantaneous radius of the winding on the winding roll.
  • a web 1 here a paper web
  • a contact or contact roller 3 with a force F k on the winding roller 2 or the winding 4 (or the winding ) pressed.
  • F k the force on the winding roller 2 or the winding 4 (or the winding ) pressed.
  • the winding roll 2 and the winding 4 bend more strongly, the different deflection differences ⁇ F between the contact roll 3 and the winding roll 2 or roll 4 leading to an uneven contact pressure curve q k over the web width, with the result 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 actuators 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 exit 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 provided in which the radius of curvature of the tops of the support plates 5 a mean radius of curvature R of the middle roll 4 is adapted.
  • 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 are articulated on the one hand with their piston rod on the support plate 5 and on the other hand on a stationary frame. Furthermore, the winding radius 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.
  • a is the lever arm or approximately the radial length of the projections 9
