Definitions

  • the invention relates to a conveyor belt with a support side and running side cover plate each made of a polymeric material having elastic properties and embedded tension members in the form of fabrics.
  • Such conveyor belts are referred to as textile conveyor belts. They are used for small and medium tensile loads on the conveyor belt, which usually the
  • Main component of a belt conveyor represents.
  • the tension members made of textile material form the carcass that transmits the carcass, which as a rule is surrounded by at least one adhesive rubber mixture.
  • the carcass is surrounded on all sides by wear-resistant rubber cover plates.
  • various breakdown protection devices can be present.
  • the carcass can be constructed, for example, from a fabric layer, from two fabric layers with a thick intermediate layer, from several fabric layers with thinner intermediate layers or from interwoven, so-called monoply, inserts.
  • polyester PET
  • PA polyamide
  • polyester has a lower elongation than polyamide, it is preferably suitable for use in the warp direction.
  • polyamide improved due to the higher elongation trough ability, especially for trough conveyor belts.
  • the polyester warp threads have a low permanent stretch, but also a low elastic elongation, resulting in a high modulus of elasticity, whereby the work capacity decreases in the impact load by the conveyed onto the conveyor belt.
  • the polyamide chains and weft threads have high permanent elongation at a high elastic elongation, ie a low modulus of elasticity.
  • Such conveyor belts with polyester or polyamide as material for the chain and
  • Polyamide as a material for the weft are u.a. in DE3137657A1, DE3631245A1, DE69715215T2 or also in EP0048332B1.
  • the textile conveyor belts are produced with polyester warp threads and polyamide weft threads, so-called EP belts, these have in the longitudinal direction, i. in the conveying direction, a comparatively low permanent elongation, so that a reduction or retightening is avoided, but at least much less necessary than PP straps.
  • the low elastic elongation i. the low work capacity, faster to damage due to the impact of the transported material.
  • the object of the present invention is therefore to provide a conveyor belt of the type mentioned, which is characterized by an improved work capacity, which improves the resistance to impact load. At the same time the disadvantages of a high permanent elongation should be avoided.
  • This object is achieved in that the fabric of the textile conveyor belt consists of warp threads of polyester and wefts of polyamide, the number of ends per Decimetre (epdm) of the chain is between 110 and 160 and the number of layers of the chain is 2 to 4, and wherein the number of ends per decimeter of the weft is between 30 and 90 and the number of layers of the weft is 1 to 3.
  • Young's modulus in the belt longitudinal direction significantly, preferably by about 40%, reduced.
  • the invention is preferably used on fabrics having breaking strengths between 100 and 630 N / mm per layer.
  • Polyester types are used. These are e.g. PBT (polybutylene terephthalate), PET (polyethylene terephthalate), PTT (polytrimethylene terephthalate), PEN (polyethylene naphthalate), PC (polycarbonate), UP (unsaturated polyester resin), POK or PEEK (polyether ether ketone).

  • the number of layers of the chain is two to four, with a particularly good
  • Resistance to impact load is achieved at a number of layers of three.
  • Polyamides may be used, such as polyamide 6, polyamide 6.6, polyamide 11, polyamide 12, polyamide 6.10, polyamide 6.12 or copolyamides.
  • the number of ends per decimeter of the weft is fiction, according to between 30 and 90, preferably between 45 and 75 and more preferably between 55 and 65.
  • the number of layers of the shot is one to three, with a particularly good
  • Resistance to impact load is achieved at a number of layers of two.
  • the support-side and running-side cover plate is constructed in each case of at least one polymeric material having elastic properties.
  • polymeric material may be rubbers, but also thermoplastic elastomers, such as, for example, polyurethane act.
  • the polymeric material is preferably a rubber selected from the group consisting of natural rubber (NR) and / or butadiene rubber (BR) and / or chloroprene rubber (CR) and / or styrene-butadiene rubber.

  • the rubbers mentioned can be used alone or in a blend.
  • CR which is characterized by high resistance to fire, weathering and aging, in particular for conveyor belts used in underground mining.
  • NR and the abovementioned blends (DE 10 2009 043 904 A1) have also become more important.
  • the cover plates may also be formed as a film or fabric, in which case said materials are also used. It is particularly preferred if the film is constructed on the basis of at least one fluoropolymer. In this case, an additional optimized media resistance is ensured.
  • the two cover plates may contain at least one crosslinking agent or a crosslinking system comprising a crosslinking agent and an accelerator, and usually further Mischingingredienzien, in particular at least one filler and / or at least one processing aid and / or at least one aging protection agent and / or at least one plasticizer and / or other additive (eg fibers, color pigments) included.

  • the conveyor belt can still be provided with a body part, for example with a driver part, guide part and with edge and side wall profiles.
  • Body parts consist of a polymeric material (rubber, thermoplastic elastomer, thermoplastic) and are glued and / or vulcanized on the foot side with the supporting surface of the elastic conveyor belt.
  • a transverse reinforcement of synthetic cords for example of polyamide (PA) or thin steel cords embedded in the support-side and / or running-side cover plate can additionally be used, see, inter alia. WO 2008/034483 AI.
  • Conveyor belt may still each have at least one adhesive layer, which optimizes the connection of the fabric to the respective cover plate.
  • composition of the adhesive layer is made at this point on the general state of the art.
