Definitions

  • the present invention relates to a conveyor belt which can be used in machines for the production of web material, such as for example paper or cardboard for forwarding such web material or the starting material therefor.
  • Conveyor belts are used in paper machines, for example, to pick up paper or the starting material for it or to move it through various processing stations, such as pressing stations. Particularly when moving through press stations or press nips, liquid is pressed out of the web material to be produced, which then collects in the area of the surface of the conveyor belt on which the web material is transported.
  • this liquid generally water
  • this web material-side surface of a conveyor belt with recesses, for example groove-like or groove-like recesses. In this way, not only is the volume required for receiving liquid created, but the provision of such depressions also has the advantage that the conveyor belt can be more easily detached from the web material.
  • EP 1 754 823 A2 is considered state of the art according to Article 54 (3) EPC and discloses a conveyor belt for the production of web material with elongated grooves running in the longitudinal direction of the conveyor belt on the machine side.
  • not or not only the surface of the conveyor belt on the web material side is not provided with depressions provided in order to be able to absorb a certain amount of liquid there and transport it away from the web material. Depressions are also provided on the machine side, so that liquid or impurities that collect on this side of the conveyor belt can be absorbed and thus a suitable static friction contact of the machine contact surface of the conveyor belt with drive rollers and the like can be ensured.
  • the conveyor belt is suitable for guiding rollers or the like that drive the movement over it, and the depressions are designed like grooves or grooves, so that a slip-free drive contact with the rollers of the machine contact surface that drive the movement is made possible and that the web material contact surface is suitable to come into direct contact with the web material to be manufactured and that the reinforcement structure is encased by a construction material which comprises polyurethane,
  • the depressions are essentially elongated in a longitudinal direction of the conveyor belt. and designed like a groove or groove.
  • the indentations should be at least 50 ⁇ m deep. It has proven to be particularly advantageous here if the indentation depth of the indentations is in the range from 100 ⁇ m to 1000 ⁇ m, preferably 200 ⁇ m to 800 ⁇ m.
  • depressions on the rear side that is to say on the machine side of the conveyor belt, has the desired effect that, as already mentioned, liquid and in particular also particles will increasingly accumulate in the area of these depressions.
  • a processing station for example a press station of a paper machine, there is again volume for receiving liquid or particles
  • the depressions have a depression surface and that the surface roughness in the area of the depression surface is smaller than the surface roughness in the area of the machine contact surface.
  • the surface roughness in the area of the recess surface is smaller than Rz 8 ⁇ m, preferably smaller than Rz 5 ⁇ m, most preferably smaller than Rz 4 ⁇ m, and if the surface roughness in the area of the machine contact surface is greater than Rz 30 ⁇ m.
  • the easier detachment of materials that collect in the depressions can also be assisted or achieved in that the depressions have a depression surface which is coated with an adhesion-reducing material.
  • the conveyor belt By designing the conveyor belt in such a way that at least some of the depressions are tapered in the direction away from the machine contact surface, a large volume or a large opening cross-section of the depressions is provided in particular immediately adjacent to the machine contact surface, so that liquid and particles or the like are easily provided can get into the depressions and can thus be quickly removed from the machine contact surface of the conveyor belt.
  • the depressions are designed to widen in the direction away from the machine contact surface. In this way, a comparatively large total volume of the depressions can be provided with an equally large machine contact surface. This has the advantage that through this comparatively large machine contact surface whose load and thus also wear can be reduced.
  • the procedure can be such that the depressions are incorporated into a conveyor belt blank.
  • the depressions it is possible for the depressions to be formed in the production of the conveyor belt.
  • this method is not protected by the claims of the invention.
  • the conveyor belt have a machine contact surface on its machine side which is provided at least in some areas with a surface roughness that is greater than the surface roughness in the region of a depression surface formed in the depressions.
  • the easier detachment of materials that collect in the depressions can also be achieved or supported by coating the conveyor belt with an adhesion-reducing material after the depressions have been provided on the machine side and the adhesion-reducing material from a machine contact surface the conveyor belt is removed.
  • the conveyor belt 10 shown in cross section is generally constructed in such a way that it has a reinforcing structure 12 formed, for example, by a fabric or other fiber material in its inner volume region.
  • This reinforcement structure 12 is embedded or surrounded on both sides by construction material 14 of the conveyor belt 10.
  • This construction material 14 can comprise, for example, polymer material, such as, for example, polyurethane. It can be composed of different materials in multiple layers, and it can be provided that different types of construction materials are used on both sides of the reinforcement structure 12. It can further be provided that the reinforcement structure 12 is encapsulated by the building material 14 or that the layered or layered material is applied on both sides or on one side. laminated construction material 14 carries.
  • the conveyor belt 10 which is basically constructed as described above with the reinforcement structure 12 and the building material 14, has a web material side 16 on which this conveyor belt 10 comes into contact with a web material contact surface 18 with the web material to be manufactured, such as paper or cardboard, or the Starting material for it.
  • a web material contact surface 18 with the web material to be manufactured, such as paper or cardboard, or the Starting material for it.
  • the conveyor belt 10 On the opposite side, that is to say a machine side 20, the conveyor belt 10 has a machine contact surface 22. With this machine contact surface 22, the conveyor belt 10 is in contact with a plurality of rollers that guide it or also drive it to move.
  • liquid In the production of web material, such as paper or cardboard, liquid, generally water, is pressed out of the building material of the web material in various processing stations, in particular in pressing stations. This collects primarily on the web material contact surface 18. In order not to press this liquid back into the web material again, that is to say to avoid rewetting, and to be able to reliably remove it from the web material, on the web material side 16 in the Fig. 1 Depressions, not shown, can be provided in which this liquid can collect. In the course of a production process, however, such liquid will also reach the rear, that is to say the machine side 20 of the conveyor belt 10. Particles released from the build-up material of the web material can also get into the area of the machine side 20 together with the liquid. This could lead to the problem that, due to a reduction in the coefficient of static friction, a required drive friction contact with one or more drive rollers can no longer be ensured and thus drive slip occurs between a drive roller and the conveyor belt 10.
  • the conveyor belt 10 is designed with a plurality of depressions 24 on its machine side 20.
  • These depressions 24 can be designed like grooves or grooves and, as shown in FIG Fig. 1 is also shown, is approximately perpendicular to the transverse direction CMD of the conveyor belt 10, so essentially in a plane to the drawing Fig. 1 orthogonally standing longitudinal direction of the conveyor belt 10, extend.
  • the depressions 24 can be arranged in a regular pattern, as in FIG Fig. 1 shown, so also have a uniform mutual spacing, or they can be provided in an irregular, statistically distributed pattern with regard to spacing and orientation and possibly also dimensioning.
  • the depression depth d of these depressions 24 should be at least 50 ⁇ m. It has proven to be advantageous if this depression depth is in the range from 100 ⁇ m to 1000 ⁇ m, preferably between 200 ⁇ m and 800 ⁇ m. In this way it can be ensured that essentially all of the liquid occurring or accumulating on the machine side 20 and also particles contained therein can be received in the depressions 24 and thus there is reliable frictional contact between the machine contact surface 22 and the drive rollers.
  • the materials received in the depressions 24 should advantageously be removed from the machine side 20 of the conveyor belt 10, for example after passing through a pressing station by using a cleaning device, such as a cleaning scraper or a cleaning brush.
  • a cleaning device such as a cleaning scraper or a cleaning brush.
  • the surface roughness in the area of the machine contact surface 22 is preferably at a value Rz of at least 30 ⁇ m, it is advantageous if the surface roughness in the area of the recess surfaces 26 is most preferred at a value of at most Rz 8 ⁇ m, preferably below Rz 5 ⁇ m is below Rz 4 ⁇ m.
  • Such a smooth surface ensures the easy detachment of materials present in the area of the depressions 24.
  • these depressions 24 are already formed or embossed during the manufacture of the conveyor belt 10, i.e. when the construction material 14 is provided by using appropriate shapes or rollers.
  • these indentations 24 with the desired indentation pattern after providing a conveyor belt blank designed essentially with a smooth machine side 20, for example likewise by pressing in or by machining.
  • the recess surface 26 and the machine contact surface 22 are generally provided with approximately the same surface roughness, which can essentially correspond to the roughness desired in the area of the recess surfaces 26, a roughening treatment can subsequently be carried out on the machine side 20 of the conveyor belt 10, to roughen the machine contact surface 22 and thus provide the desired surface roughness there. In this way, it becomes possible to provide different surface roughnesses in the area of the depression surface 26 on the one hand and the machine contact surface 22 on the other hand.
  • the removal of materials contained in the depressions 24, for example in a cleaning station, can thereby be made even easier or easier.
  • an adhesion-reducing layer This can be made of Teflon (PTFE), for example.
  • PTFE Teflon
  • the procedure can be, for example, that after the conveyor belt 10 with the depressions 24 has been provided, the entire machine side 20, i.e. the depression surfaces 26 and the machine contact surface 22, with this adhesion-reducing material with a primarily for the coating the recess surfaces 26 are coated with a suitable or desired layer thickness.
  • the machine side 20 can then be subjected to a roughening or removal treatment, in which the adhesion-reducing material deposited on the machine contact surface 22 is removed again and the desired surface roughness is provided in the area of the machine contact surface 22.
  • FIG. 2 An alternative embodiment of a conveyor belt is shown in Fig. 2 shown.
  • the same components or partial areas of the conveyor belt are denoted by the same reference symbols as in FIG Fig. 1 .
  • depressions 24 with the contour or shape tapering away from the machine contact surface 22 ensures that where these depressions 24 adjoin the machine contact surface 22, comparatively large openings are formed, so that what is present on the machine side 20 and in the depressions 24 material to be picked up quickly and reliably enters these depressions 24.
  • FIG Fig. 3 Another modification with regard to the shape of the depressions 24 is shown in FIG Fig. 3 shown. It can be seen here that the depressions 24 are approximately rectangular or square in the illustrated section, i.e. an approximately constant depression dimension in the direction away from the machine contact surface 22, with an elongated configuration, in particular an elongated configuration in the longitudinal direction of the conveyor belt 10, i.e. an approximately constant width exhibit. This leads to a very stable arrangement that deforms only slightly under pressure loads and thus approximately maintains the predetermined volume of the depressions 24.
  • the depressions 24 are designed to widen in the direction away from the machine contact surface 22.
  • a cone-like or dovetail-like widening shape of the depressions 24 is provided.
  • the advantage of this embodiment variant is that with a comparatively large volume of the depressions 24, the interruptions generated by these depressions 24 in the machine contact surface 22 are significantly smaller than, for example, in the case of the depressions 24 Figs. 1 and 2 embodiment shown. That is, in a conveyor belt 10 with the in Fig. 4 The overall machine contact surface 22 provided in the structure shown is larger for the same dimensioning of the conveyor belt 10. This leads to a relief of the conveyor belt 10 on the machine contact surface, since pressure loads occurring are distributed over a larger machine contact surface. This is a very advantageous embodiment, especially with regard to the wear that occurs during operation.
  • Fig. 5 a top view of the machine side 20 or the machine contact surface 22 of a conveyor belt 10 can be seen. Here, too, only a partial section of such a conveyor belt 10 is shown.
  • the depressions 24 are not elongated in a longitudinal direction of the conveyor belt 10 or a transverse direction of the conveyor belt 10, but are designed as discrete depressions. As in Fig. 5 shown, be designed with a circular shape, but can, for example, also be oval, square, elliptical or the like. Of course, as shown above, these discrete depressions 24 can be designed to taper away from the machine contact surface 22, to widen or to be designed with approximately constant dimensions. These discrete depressions 24 can be distributed on the machine side 20 in a regular pattern, as shown in FIG Fig. 5 is recognizable, or can be statistically distributed, with the statistical distribution also being able to ensure that a specific total volume of the depressions 24 is provided for each predetermined area unit.
  • This in Fig. 5 discreetly discernible depressions 24 can be introduced, for example, as blind bores, but can also be provided in that a volume area of the conveyor belt 10 or of the construction material 14 having these depressions 24 in Is applied or laminated in the form of a film or layer, wherein the depressions 24 with the desired shape, distribution and size can then be provided in this film or layer of the building material 14.
  • the depressions can extend with constant dimensions in a partial area of their extension length, while a tapering or possibly widening contour is specified in a subsequent area.
  • a combination of widening and tapering sections of respective depressions is also possible, as is the combination of depressions of different shapes on one and the same conveyor belt.
  • a conveyor belt 10 ensures in a simple and reliable manner that contaminants or moisture reaching the rear of the conveyor belt, i.e. the machine side, do not impair the running properties of the conveyor belt 10 over the rollers that guide or drive it.
  • sufficient static friction contact between the machine contact surface and the leading or driving beams can be ensured.
  • the design of the depressions can ensure that materials that collect therein, such as water and particles emerging from the starting material for the web material, can easily be removed from the depressions, so that these depressions are prevented from gradually closing over the service life can be.
  • the shape, the direction of extent, the depth and the surface density of the in Fig. 1 recognizable depressions 24 in adaptation to the in use too expected environmental conditions can be selected.
  • the way in which these depressions can be provided, for example by molding, pressing in, removing material, drilling in or the like, can also be selected so that the depressions then formed are optimally adapted for the respective application conditions.
