Definitions

• the invention relates to an endless conveyor belt with a multi-layered structure, with at least one layer forming a support side of a fabric, and with a running side forming layer, with an arranged between the support side and the running side, forming a tension member layer by means of an adhesive layer inseparable from each other are connected. Furthermore, the invention relates to a transport device equipped with this conveyor belt with a sliding arrangement of the conveyor belt on a sliding table of the transport device.
• Such a conveyor belt consists in practice of a tension member, which is enclosed on the one hand by a layer forming the support side or coating, on the other hand by a running side forming layer or coating.
• Belt conveyors are generally known which have a conveyor belt with an upper leading section (upper run) and a lower returning section (lower run). Usually, for this purpose, the belt conveyors have an overlay forming slide table on which slides the load-bearing Trum. Such conveyors are used for general cargo and / or passenger transport, for example in the automotive industry as running parallel to the actual assembly line "Werkermitf ahrband”.
• a belt conveyor is known, the upper run of which is removed by means of a sliding table, which is located on a rail. supported on the floor supporting frame.
• the (unloaded) lower strand is removed by rolling rollers.
• the support side is optimized by various coating materials, thicknesses and structures with regard to the transported material and the desired chemical, physiological and mechanical properties of the band.
• the tensile strength and the fabric used for this purpose greatly affect the suitability for use. In particular, this determines the strip running properties, the force / elongation behavior, electrostatic properties, the flatness, as well as the knife edge and curve suitability.
• the running side and its properties significantly determine the noise emission, the energy consumption as well as the wear and the usability for the sliding support of the conveyor belt.
• the support side and the running side can be realized for example by plastic or elastomeric coatings, with countless variants can be realized for different conveyor belt types and designs and the diverse requirements of the practice.
• a conveyor belt with the aim of minimizing friction is known, for example, from EP 2 259 989 B1.
• the conveyor belt has first and second fabric layers of polyester fabric interposed therebetween containing polyurethane, polyvinyl chloride and a flame retardant.
• EP 1 281 639 B1 discloses a perforated strip, preferably made of metal, with attached non-stick coating which comprises PTFE (polytetrafluoroethylene), silicone or nanoparticles.
• PTFE polytetrafluoroethylene
• the invention has for its object to provide a way to reduce the cost of producing a friction-optimized conveyor belt. Furthermore, the invention has for its object to provide such a equipped transport device in which the frictional resistance occurring during operation between the slide table and the running side of the conveyor belt is reduced.
• the first object is achieved with a conveyor belt according to the features of claim 1.
• the further embodiment of the invention can be found in the dependent claims.
• a conveyor belt in which the adhesion layer between the layer forming the running side and the tension member contains a composition having a first portion of an adhesive and a second portion of a lubricant.
• the invention is based on the surprising finding that the lubricant does not or not appreciably reduces the adhesive properties between the two layers connected thereby.
• This accumulation of the lubricant can for example be carried out flat on the running side and form there another layer.
• the production cost is reduced and the costs are reduced.
• the lubricant when it comes to a removal of the same on the running side during operation, from the intermediate region between the layers travels and thus for a very long period of time, a sufficient amount of the lubricant on the running side is available.
• the invention is based on the surprisingly surprising for the expert knowledge that the separation strength between the running side forming layer and the tension member is not reduced due to the introduced between these composition, although after the prejudice in the art, the lubricant would affect the formation of the compound.
• the concentration of the lubricant on the basis of a homogeneous distribution does not affect the connection.
• the free components of the lubricant migrate in the composition and thus penetrate to the surface, ie the outer surface of the running side, accumulate there and lead to an increase in the local concentration.
• the initially homogeneous distribution in the composition initially results in that the proportion of the lubricant in the region between the tensile carrier and the running side does not or does not substantially impair the adhesive properties of the composition, based on the proportion of the adhesive.
• This resulting adhesive compound is independent of subsequent changes in the local concentration in the composition of the here primarily effective physical reaction.
• the acting as a barrier adhesive compound favors the later occurring migratory movement to this remote free surface, through the running side layer through to the outside of the running side, where it comes as a result to a local increase in concentration in favor of the lubricant content.
• the composition comprises PVC powder, plasticizers, stabilizers, adhesion promoters or PU adhesives.
• isocyanate is suitable for this purpose, if appropriate in conjunction with a dye. The isocyanates crosslink and react with the polyester fabric of the layer of the tension member.
• the tensile carrier creates a physical bond in the adhesion layer, while with respect to the outer layer, a chemical reaction leads to the bond.
• a reaction between the isocyanate and the lubricant, for example silicone does not take place. Both compounds are not changed after their reaction by subsequent diffusion of the lubricant components, however, the physical connection can form a barrier for the lubricant impermeable barrier layer, while the chemical bonding for the lubricant components is at least limited permeability.
• the lubricant contains natural or artificial waxes, silicones, polysiloxane and / or polydimethylsiloxane.
• the second object is achieved according to the invention with a transport device equipped with the conveyor belt with a serving for supporting the conveyor belt slide table with a contact surface for the running side of the conveyor belt.

• FIG. 4 shows a further variant of a conveyor belt with two traction carriers enclosing an intermediate layer and two friction-optimized outer layers.
• FIG. 1 shows a schematic illustration of a transport device 2 equipped with a conveyor belt 1 with a sliding arrangement. For this purpose, an upper run 3 is supported on a slide table 4.
• the endless, serving as a conveyor belt conveyor 1 has a multilayer structure, with at least one forming a support side layer 5 of a fabric and with a running side forming, in particular designed as a coating layer 6 with a train carrier forming layer 7 by means of a Adhesion layer 8 are inextricably linked in use.
• the adhesion layer 8 between the running side forming layer 6 and the tensile carrier has a composition comprising a first portion of an adhesive and a second portion of a lubricant.
• the invention is based on the discovery that is surprising for the person skilled in the art that the release strength between the layer 6 forming the running side and the layer 7 forming the tension carrier is not reduced due to the composition introduced between them. On the contrary, due to the initially homogeneous mixture in the composition, an insoluble connection of the running side with the layer 7, which is unchanged compared to the adhesion compounds known from the prior art, forms.
• the resulting contact surface forms a blocking surface for the subsequent migration of the second portion of the composition, which moves due to the one-sided barrier layer mainly in the opposite direction and there leads to a local increase in the concentration of the lubricant.
• the lubricant portion penetrates the running side and deposits on the outside of the layer 6 increasingly.
• FIG. 2 additionally shows a variant of a conveyor belt 9 with a layer 10 formed by a fabric and serving as a running side, which is connected to the layer 7 forming the tension carrier by means of the adhesion layer 8.
• the conveyor belt 9 has a substantially coincident construction with the conveyor belt 1 shown in FIG. 1 with a layer 5 forming a carrier side made of a fabric.
• a variant shown in Figure 3 of a further conveyor belt 1 1 differs from the transport belt 1 shown in Figure 1 by two identical, parallel, each forming a tension carrier layers 7, which are permanently connected by a contact layer 12.
• the lower of the two layers 7 is by means of the adhesion layer 8 is bonded to the running side forming layer 6.
• the permissible tensile force can be increased in a simple manner.
• FIG. 4 shows yet another variant of a conveyor belt 13 with two layers 7 comprising a fabric 14 and two friction-optimized layers 6 forming an intermediate layer 14 each forming an outer layer Layers 6 can therefore be used either as a support side or running side.
