Definitions

  • the invention relates to a winding machine for winding, possibly longitudinally divided, webs, preferably paper webs, with the features of the preamble of claim 1.
  • the wind box has side wall areas in the form of segments of a circle, which are adapted in shape to the outer cross section of the two support rollers in such a way that the smallest possible uniform gap remains between the outer wind box surface and a circular arc piece of the support rollers.
  • the web to be wound is preferably passed through one of these two gaps.
  • the two support rollers are arranged stationary, the great length of the support rollers, which can exceed 8 or 10 m, places high demands on the exact setting of the smallest possible Stand gap between the support rollers and the parallel side wall parts of the wind box. Since the gap between the looped support roller and wind box is too small when changing rolls or re-threading a web to be wound, it is provided according to DE 41 10 047 AI, the wind box to be pivoted downward on an arm mechanism which is guided around the wrapped support roller. The movement of the wind box as a whole places considerable demands on the positioning of the wind box in the working position, in which on the one hand excessive air gaps, ie high compressed air consumption, and on the other hand any contact between the wind box and the support roller are to be avoided.
  • Sealing of the upper gusset space is only required at the front ends, but the problem that has to be overcome here is that the sealing surfaces available are relatively small, which makes contact-less sealing with less pressure loss possible.
  • the sealing surfaces provided for the sealing task can only be brought into position when the winding to be produced has reached such a large diameter that the sealing surfaces can be pivoted between the winding tube guide and one of the support rollers. Because of the considerable width of the upper gusset space in the case of large end winding diameters, this is only possible from a relatively large winding diameter.
  • the pivotability of the upper and lower part of the wind box requires that the parting plane be placed at the narrowest point between the support rollers, which further increases the sealing problems.
  • the aim of the invention is to reduce the sealing problems in winding machines of the generic type.
  • Another object of the invention is to relieve the pressure of the roll to be produced from just one To enable particularly small winding diameter and thus to improve the winding structure.
  • Another object of the invention is to improve the winding structure by combining support rollers with a resilient surface, in particular with different resilience of the support roller surfaces and applying the pressure relief principle (airlift principle).
  • Another object of the invention is to automate the threading of the web to be wound between the support rollers into the winding position in the case of generic winding machines.
  • the features of claim 2 in particular in combination with the features of claim 3, facilitate the threading, in particular the automatic threading of the web to be wound between the support rollers into the winding start position.
  • the sealing means of the lower gusset region can remain stationary in position between the two support rollers due to the pivotability of the one side wall of the wind box and - according to claim 5 - preferably also remains, it becomes possible for the first time to arrange the horizontal dividing point between the sealing means for the lower and upper gusset area clearly above the narrow point between the two support rollers and thus to significantly improve the sealing options and the positioning accuracy of the side walls of the wind box .
  • This possibility is further improved by the feature of claims 6 and / or 7.
  • FIG. 2 shows the winding machine according to FIG. 1 in the same view in a working position during compressed air-supported winding
  • Fig. 3 seen the same winding machine in a front view from the direction of the web feed, with the first carrier roller as well as 4 of the same winding machine, the end sealing surfaces for the upper gusset space in a view from above in two working positions of the pivotable partial surface.
  • two axially parallel support rollers TW1 and TW2 with a constant minimum spacing gap G of their radial lateral surfaces M1 and M2 are rotatably arranged. At least one of the support rollers can be driven.
  • the jacket M1, the first carrier roller TW1 in the web running direction, is more elastically deformable than the jacket M2, the second carrier roller TW2 in the web running direction.
  • both support rollers have the same diameter and are at the same height level, but the diameter and height levels can also be different.
  • the first support roller has the larger diameter and the lower axis position. That of the two support rollers, the total load resulting from static and dynamic loading during winding is the greater of the two support rollers, has the jacket which is more elastically deformable by both support rollers.
  • Frontal sealing surfaces 14 for the upper gusset area are pivotally mounted about the axis TWA2 of the second support roller TW2 by means of a piston / cylinder unit 20 and a two-armed lever 21, so that they can be pivoted into the working position shown and out of it for the first winding phase are.
  • the radially outermost region of the sealing surface 14 with respect to the pivot axis TWA2 is as Partial surface 14A designed, which is pivotable from the sealing position shown about a substantially perpendicular to the winding axis 15 pivot axis 15 by approximately 90 °, so that the pivoting radius SR of the sealing surfaces 14 in comparison with the part R 14 pivoted away from the winding is reduced to the partial surface 14A lying against the winding R.
  • FIG. 4 shows the sealing position with solid lines and the pivoting position with dash-dotted lines.
  • a piston / cylinder unit 22 is used for pivoting.
  • a sealing plate 19 which extends approximately parallel to the support roller axes and which extends axially outward from extends the sealing surface 14 and, in cooperation with a sealing table 18 of a wind box 16, which is yet to be explained, allows the wind box to be sealed between the upper and lower gusset areas with different winding widths.
  • FIG. 3 solid and dash-dotted position of the sealing surfaces 14 and sealing plate 19
  • the lower gusset area between the two support rollers TW1 and TW2 and the lower zone of the upper gusset area are sealed by a wind box 16 which is arranged in a stationary manner and is open at the top, so that in interaction between the latter, the two support rollers, the coil and the sealing surfaces.
  • Chen 14 creates a pressure chamber DR which is closed on all sides and which can be pressurized with compressed air (airlift fluid) at the lower end of the wind box 16 via a plurality of pipe stubs 25 arranged along the width of the support rollers.
  • the wind box 16 is supported by stationary supports 26.
  • the wind box 16 consists essentially of a base plate 27, which is pierced by the pipe socket 25, of a stationary, essentially circular arc-shaped side wall 28, which is adapted to the shape of the second support roller TW2 while leaving a minimal sealing gap and is rigidly attached to the wind box 16 , and from a side wall 11 which extends essentially over the entire maximum web width of the roll to be produced and which is pivotable about a pivot axis ILA, which extends approximately parallel to the support roller axes.
  • This side wall 11 can be swiveled sealingly against the support roller TW1 wrapped by the web PB to be wound, leaving a web passage gap GP open for the winding process (FIG.
  • the desirable stability of the sealing table 18 at the upper ends 17A of the end walls 17 of the wind box 16 is achieved by diagonal struts 31. Guiding surfaces 12 extending over the machine width extend the web passage gap GP formed by the pivotable side wall 11, widening the gap in the direction of the incoming web PB. Compressed gas nozzles 13 arranged in the guide surfaces 12 facilitate threading the web to be wound and placing it on the wrapped support roller TW1.
