Definitions

  • CONVEYOR BELT WITH A PROFILED SURFACE AND METHOD FOR CONNECTING THE BOTH TAPES OF SUCH A CONVEYOR BELT
  • the present invention relates to a conveyor belt with a profiled surface for conveying goods that can be rolled and to a method for connecting the two belt ends of such a conveyor belt.
  • Conveyor belts with a profiled surface are used, for example, for the transport of luggage at airports, of agricultural products, such as Potatoes or beets, or from other coarse bulk goods.
  • Such conveyor belts must be constructed and their surface designed in such a way that they have the following properties:
  • Conventional conveyor belts with these properties are generally characterized by a surface with an embossed grid pattern.
  • the bars of the grid pattern are between 2 and 5 mm high, about 3 to 10 mm wide and generally form squares or rhombuses with an edge length between 20 and 100 mm.
  • FIG. 1 shows an example of such a conveyor belt 1 'with a conveyor belt surface 10' and webs 11 '.
  • woven fabrics are generally used as the substrate, to which soft PVC, thermoplastic polyurethane or other thermoplastic elastomers are applied in a coating or melt-coating process.
  • Several such coated fabrics can be connected to multilayered bodies in a lamination process.
  • Conveyor belts with one, two or more fabric layers are conceivable.
  • the surface of the conveyor belt is embossed directly after coating or lamination or in a separate process in a dedicated embossing station.
  • FIG. 2 shows the embossing of a conveyor belt surface in an embossing calender 8 with a vertical roller arrangement.
  • a conveyor belt 1 ' is guided over a spreader 81 and a deflection roller 82 into the nip between a cooled embossing roller 83 and a rubberized counter-pressure roller 84 and then loops around the embossing roller 83.
  • the thermoplastic layer to be embossed is heated to the forming temperature or higher with infrared radiators 89.
  • the desired profiling is then pressed in by means of the engraved embossing roller 83, the pressure required for this being ensured by the rubberized counter-pressure roller 84.
  • the counter-pressure roller 84 can be cooled by means of a cooling roller 85 which is partially immersed in a cooling basin 86 filled with cooling liquid.
  • the embossed surface profile is fixed by cooling the thermoplastic layer.
  • Conveyor belt 1 'then arrives at cooling cylinders 87, 88 via deflecting rollers 90 and is guided around them for further cooling and is finally led away via a deflecting roller 91.
  • the webs form crossing points which have a disadvantageous effect on the conveyor belt.
  • the crossing points stiffen the conveyor belt, which increases the bending resistance and has an unfavorable effect on the minimum permissible roller diameter.
  • cavities can arise during the production of the embossing at the crossing points, which form the starting points for cracks and breaking points in the webs and result in poor optical quality.
  • a conveyor belt with a profiled surface is to be created for the transport of goods that can be rolled, the webs of which result in significantly less stiffening of the belt and with less - 4 -
  • the conveyor belt should also have good driving properties and the property that there is no rattling noise with deflection rollers which act on the belt surface.
  • Conveyor belt with a profiled surface for the transport of goods that can be rolled the conveyor belt surface has several continuous, longitudinal, non-straight webs that do not touch.
  • the conveyor belt is more flexible and less susceptible to imperfections and errors emanating from them than the conventional profiled conveyor belts.
  • the continuous webs prevent the installation of imperfections, e.g. Air pockets during the embossing process.
  • the absence of dead corners also prevents dirt from accumulating and increases ease of cleaning.
  • the webs are continuous and not interrupted in the longitudinal direction, they are permanently in contact with any rollers and do not generate a rattling noise.
  • the two belt ends of a conveyor belt according to the invention are connected to one another in such a way that the webs run continuously over the connection zone. This also prevents the generation of a rattling noise in the connection zone.

They have a height h between 2 and 10 mm, a lower web width b 2 between 2 and 12 mm, an upper web width b ⁇ between 2 and 12 mm and in the present case a trapezoidal cross section.

  • the conveyor belt 101 can be made endless using a method according to the invention for connecting the two belt ends 105 and 106, which comprises the following steps: a) punching out complementary tines on the two belt ends 105, 106; b) interlocking of the two band ends 105, 106; c) placing an engraved metal plate on the connecting zone 107 of the two belt ends 105, 106, the engraving corresponding to the surface geometry of the conveyor belt 101 in the connecting zone 107; and d) pressing the metal plate against the conveyor belt 101 with the application of heat, which is usually done in an end connection press.
  • the punching out of the teeth must be coordinated with one another at both band ends 105, 106 in such a way that when the two band ends 105, 106 are interlocked, a continuous profile is created in the connecting zone 107.
  • This requires a complementary arrangement of the prongs with respect to the surface geometry at the two band ends 105, 106.
  • the number of permitted prong arrangements with respect to the surface geometry is advantageously limited to 3 to 5.

Abstract

L'invention concerne un transporteur à courroie (1) à surface profilée (10) pour le transport de marchandises pouvant rouler. La surface (10) du transporteur à courroie présente plusieurs nervures (11) continues, ondulées dans le sens longitudinal et ne se touchant pas. L'agencement des nervures (11) selon l'invention évite les points d'intersection; ainsi, le transporteur à courroie (1) est plus souple et tend moins que les transporteurs à courroie traditionnels aux imperfections et aux défauts dus à de tels points d'intersection.
