Definitions

  • the invention relates to a device for winding or unwinding web-like material, in particular fibrous webs, in particular with the Features from the preamble of claim 1.
  • the G 91 15 481 relates to a winding machine for axleless unwinding Train.
  • This has at least one support roller and a device for Relieve one or more carrier rollers of the weight of the windings Role.
  • the relief device comprises a device for applying Compressed air on the outer surface of the roll to be wound, i.e. that of both Carrier rolls are additionally carried by compressed air in Direction of gravity supported.
  • a device designed in this way for or unwinding of web-like material requires appropriate measures for sealing when applying compressed air to the lateral surface of the roll to be wound or unwound. This leads to an increase the design effort, especially in such designs the web feed problematic.
  • G 92 04 667 The possibility disclosed in G 92 04 667 consists in lowering the front support roller and installing a rubberized roller as the front support roller.
  • This has the advantage that the line force on the front carrier roller is larger, but smaller on the rear.
  • the winding roller is then supported more on the front than on the rear carrier roller.
  • This effect increases with increasing roll diameter.
  • the first press nip in the running direction which is generally considered to be of greater importance for the winding result, is subjected to less stress, in particular in the case of large roll diameters, than in the case of conventionally designed devices.
  • a rubber-coated carrier roller is installed there. This increases the nip width in the second nip.
  • tests have shown that a desired increase in performance, in particular an optimal winding result, is not achieved with such a device.
  • a rubberized roller as described in G 92 04 667, is used here Shoe roller used.
  • This comprises a flexible, tubular jacket as well as, for example, a circular cylindrical hollow support, which has support elements for the jacket.
  • the carrier is a themselves over the length of the carrier or essentially over the Carrier width, assigned to the web width, of a tread which is lubricated hydrodynamically, and concave accordingly the maximum winding diameter is formed.
  • a pressure roller is provided, which enables the Press the winding tube against the load-bearing surfaces. So the shoe roller and thus the carrying shoe the much larger proportion of the winding weight wears, it is necessary that the support shoe on a significantly lower Level is arranged as the top surface line of the rigid support roller.
  • the carrying shoe At the beginning of the winding process, in which only a small winding tube is present, the carrying shoe is in a lower position. With As the winding diameter increases, the carrying shoe becomes more and more pivoted above, so that as with conventional double roller rollers on two elongated areas spaced apart on the circumference of the winding are, this is worn.
  • the disadvantage of such an arrangement is in that the radius of curvature of the support shoe is smaller Diameters of the winding does not correspond, so that none here significant advantage over a conventional double carrier roller consists.
  • the wrap is one size in the area of its maximum Diameter has reached, the wing on which the winding is increased supported on the support shoe 5, significantly. A relief is only found at Reaching a certain, approximately the maximum winding diameter corresponding diameter of the winding roll instead.
  • the device for Winding of web-like material includes two support rollers endless, elastic tensioned by a movably mounted tension roller Tape to relieve the pressure of the winding roll in the winding gap.
  • the elastic band wraps around one of the two support rollers and the Press roll.
  • the rollers wrapped in the belt are so spatial arranged that during the entire winding process by the elastic band a relief component on the weight of the winding roll arises.
  • US-A-5 240 198 describes a support roller for a winding machine. This has a hard core and a soft cover. The soft cover is with grooves that are open to the outside. This However, the device has not proven itself since it is not an optimal one Provides winding result.
  • DE-U-87 17 259 discloses an apparatus for winding web-like material.
  • the roller shell is perforated by a surrounding elastic layer.
  • the perforation is vacuumed.
  • Such Suction leads to the creation of a hole pattern in the paper web, which is undesirable.
  • EP 0 683 125 A2 describes a roll for winding or unwinding paper, with a jacket made of elastic material.
  • the coat has a relatively large size Hardness, which is effectively reduced by a pattern large proportion of gaps is introduced into the surface of the jacket. On this way, on the one hand, a long lifespan due to hard Material and at the same time a large contact area due to the softening realized with gaps.
  • the object of the invention is therefore to provide a device for or unwinding of web-like material of the type mentioned at the outset, i.e. to develop a double carrier roller, such that the above Disadvantages are avoided.
  • the focus is on achieving one optimal winding result, i.e. the receipt of a winding roll free of beads or similar winding errors.
  • a device for winding or unwinding web-like material, in particular fibrous webs with at least two Carrier rollers to which the roll to be wound up or unwound can be assigned in such a way that this with the two support rollers each at least indirectly a nip forms, the individual elements of the support device designed in this way and arranged that at least in the area of a nip, preferably the in Direction of winding second nips, alternatives for the in the Nip area elastically deforming areas of each, a nip forming elements provided on the part of the support facility are. This ensures that no shear stresses from the nip-forming elements on the part of the support facility on the ground of elastic deformations are transferred to the winding roll.
  • the inventors have recognized that the positive effects of Versions according to the status specified in documents (2) to (4) the technology caused by a damaging influence of a soft nip, in particular a soft second nip in the fiber web winding direction can be reduced again.
  • the front carrier roller used rubber cover compressed in the middle of the nip. analog also applies to an elastic support band according to one embodiment according to the document (4). Since this is for the cover of the carrier roller or material used for the support band, generally rubber, in volume is incompressible, the displaced material must come out of the nip move out. This will mainly be in the machine longitudinal direction do and beads in the area of the inlet and the outlet from the nip form.
  • Improvement measures are therefore in accordance with the invention provided, for example, that in the second nip on the winding roll transferred shear stresses by providing alternative volumes be significantly reduced or avoided entirely. To do this in essentially two solutions that can be combined and can be realized on its own through several modifications can.
  • the first-mentioned cavities can be designed as bores, grooves or the like.
  • the holes can extend in the form of through holes through the cover and the roller body of the support roller. Blind holes are only provided in the cover. These can be arranged, for example, in the area of the reference inner surface and the reference outer surface.
  • the grooves can be circumferential, spiral or in Be arranged inclined to each other extending circumferentially. Also for them Grooving is possible in the area of the outer surface and / or the inner surface of the cover. In the first case, they can can also be closed with a top layer.
  • the holes, grooves or other cavities are included an easily compressible material, such as foam. This has the advantage of preventing pollution and as little noise as possible. It is also conceivable that Seal cavities with a thin top layer on their surface. This measure can also be combined with the filling of the cavities become.
  • a second additional option is to use one or more layers constructed cover so that the top layer, which with the Winding roll comes into contact, is particularly stiff in the circumferential direction.
  • This can be done by using multi-layered covers the outer layer is hard and the inner is soft, and that with a multi-layer cover, the inner one Layer is provided with cavities according to the explanations above. It is also conceivable to have a rigid reinforcement in the cover in the area of the Surface, i.e. in the area of the outer circumference of the support roller.
  • a support roller designed according to the invention with volume-compressible areas can be used in various support roller winding devices.
  • the individual support rollers can be arranged such that the plane of connection between their two axes forms an angle with the horizontal or coincides with it. Furthermore, in both cases the support rollers can have the same diameter or different diameters. Only one or both carrier rollers can be designed according to the invention. The selection is always made according to the application requirements.
  • the variants mentioned can also be used with the already known conventional ways to increase performance be combined.
  • the compressed air box with a separator for the web-like material Mistake can also be used with the already known conventional ways to increase performance be combined.
  • the inventive design and execution of a device for or winding of web-like material enables an increase in performance in that larger diameter rolls without roll defects, such as for example, bursts or crepe folds can be generated, since none disruptive factors occur when winding or unwinding in the nips.
  • the positive effects of those described in documents (2) to (4) Executions can be retained while the negative ones Effects by using appropriately designed support rollers or Support bands can be largely switched off.
  • the basic idea The invention consists essentially in one Double roller roller at least one of the two nips, which the Can form winding roll with the two support rollers, usually the in Direction of winding second nip, as an almost soft nip, in which however no shear stresses are transmitted to the winding roll.
