Definitions

  • the invention relates to a conveyor belt system with a conveyor belt extending in a conveying direction and support roller arrangements spaced apart from one another along the conveyor belt, each having six support rollers distributed annularly around the outer circumference of the conveyor belt, whereby the conveyor belt is formed into a hose, wherein the support roller arrangement in each case one First group with support rollers and at least one staggered in the conveying direction and circumferential direction supporting role have.
  • Conveyor belt systems are used for the transport of various bulk materials, such as overburden, ores, fuels, building materials or the like.
  • the conveyor belts are often in the form of a trough on perpendicular to the conveying direction support rollers or run to a tube formed by annularly arranged support rollers.
  • the support rollers of a support roller assembly are usually arranged on support means in the form of carrying roller stations, Tragrollengirlanden or carrying roller chairs.
  • a trough-shaped conveyor belt usually three support rollers are arranged in the same cross-sectional plane on the support roller assemblies.
  • annular arrangement of, for example, six support rollers for forming a hose
  • the support rollers of the second group with respect to the support rollers of the first group in the circumferential direction and in the conveying direction have an offset
  • the offset in the conveying direction is particularly intended to allow a certain overlap of circumferentially successive carrying rollers with respect to a cross-sectional plane. So it is known, on a common carrier of a carrying role station, the carrying rollers of the first group on the one hand and the
  • a conveyor belt system with a conveyor belt shaped into a tube is known from US 2010/0018841 A1, wherein the conveyor belt has a shape that approximates a polygon in the region of the spaced support roller arrangements. This is due to the fact that the conveyor belt at the individual support rollers at least partially flat. The circumference results in flat areas with relatively strong bends therebetween. Outside the carrying-roller arrangements, the free-hanging conveyor belt assumes an approximately circular or oval cross-sectional shape with a substantially uniform curvature.
  • a further conveyor belt system with a conveyor belt shaped into a tube is known from JP 08175642 A, wherein mutually spaced support roller arrangements each have six carrying rollers.
  • the six carrying rollers of one carrying roller station are rotated in the circumferential direction in relation to the six carrying rollers of the subsequent carrying roller station.
  • the formed to a hose conveyor belt on the support roller assemblies each having approximately the shape of a hexagon.
  • a division of the six support rollers of a support roller assembly is not provided.
  • the support roller assemblies in the form of carrying roller stations, Tragrollengirlanden or Tragrollenstühlen usually consist of identically constructed and arranged in the same circumferential position support rollers which are distributed with an approximately equal distance in the conveying direction over straight sections, wherein in vertical and / or horizontal curves of the distance between the individual support roller assemblies is shortened expediently.
  • the support roller assemblies are arranged along a polygon.
  • the main resistance to movement is primarily determined by carrying roller idling, indenting roller, oscillating bending and conveying goods resistance. It accounts for the last three resistors, which are referred to in the sum as Inteltwalkwiderstand, often the largest part of the resistance to movement.
  • the total walking resistance can make up more than 90% of the main moving resistance.
  • the total walk resistance is determined by a complex relationship between the idler shape and arrangement, the spacing of the idler assemblies, the belt tension, the belt tension stiffness, the belt load, the radii of curves, and other design factors.
  • the present invention has for its object to provide a conveyor belt system in which the main movement resistance is reduced, whereby in addition to a reduction of the drive energy and the tendency to wear can be reduced and thus the reliability can be increased.
  • the object is achieved in that the along the conveying direction certain distance between the first group of support rollers and the at least one staggered arranged support roller of the same

  • the circumferentially distributed support rollers of a support roller assembly are seen in the conveying direction positioned at a considerable distance from each other.
  • the present invention is based on the finding that the support rollers of a support roller arrangement arranged essentially in one plane according to the prior art constitute a type of bottleneck through which the conveyor belt and in the filled state also the contents have to be pressed or pulled through ,
  • the distribution of the support rollers of a support roller assembly in the conveying direction can be used both with conveyor belt systems with a trough-shaped conveyor belt as well as conveyor belt systems with a conveyor belt closed to a hose.
  • the advantages are particularly significant in a closed conveyor belt to a hose, because there are particularly strong changes in geometry and constraints.
  • the support rollers arranged essentially in one plane of a support roller arrangement around the entire circumference, the cross-sectional area of a polygon, so that for the conveyor belt, in particular in the filled state, no space for free expansion is present.
  • the deformation is significantly lower, so that the total resistance kross in the invention is significantly reduced.
  • the six annularly arranged support rollers of a support roller arrangement are divided into two axially spaced-apart groups of support rollers.
  • the division can be done in different ways. In addition to a uniform division, in which each group has three support rollers, configurations with a 4: 2 and 5: 1 division are possible. In a division 5: 1, therefore, the first group has five support rollers, while the second group has only one support roller. Where the only support roller of the second group is provided, accordingly, the first group has a free space into which the tubular belt can spread. In an arrangement of 5: 1, for example, the lowest support roller can be arranged separately.
  • the conveyor belt can also be guided more easily along curves by the intermediate support.
  • the conveyor belt is supported by the spaced arrangement of support rollers not along a curved arc but along a polygon. While according to the prior art, the support rollers of a support roller assembly are substantially in one plane, takes place within the scope of the invention by the division of the support rollers in the conveying direction an intermediate support, so that thereby the angling is less.
  • the first group and the second group each have three support rollers, which are arranged relative to the cross-sectional area with an angular pitch of 120 ° to each other around the circumference.
  • the carrying rollers of one group are provided precisely at the gaps between the carrying rollers of the other group.
  • the distance between the first group of support rollers and the at least one staggered support roller or the second group of the same support roller assembly between 10% and 90% of the distance between successive support roller assemblies, for example, by the distance of the respective first group the two support roller assemblies is determined.
  • the expansion of the support rollers themselves is not taken into account in the determination of the distances, so that it is always assumed that the position of the axes of rotation of the support rollers.
  • the support rollers of the first group and the second group are each arranged approximately in a plane. For practical reasons, however, the support rollers of a group may also have a certain offset with respect to one another in the conveying direction, in which case an average must be assumed for determining the distances.
  • the distance along the conveying direction between the first group of support rollers and the at least one staggered support roller or the second group of the same support roller assembly between 20% and 80%, particularly preferably between 25% and 75% of the distance from the first group of the support roller assembly to the first group of subsequent support roller assembly in the conveying direction.
  • the staggered support roller or second group may be positioned approximately centrally between the first group of the associated support roller arrangement and the first group of the support roller arrangement following in the conveying direction.
  • All support rollers of a support roller assembly can be arranged on a common support means in the form of a support roller station, a supporting role garland or a carrying roller chair, but then spacer arms or the like are provided to the support rollers of the first group and the at least one staggered arranged support roller with a sufficient distance in Position conveying direction.
  • spacer arms or the like are provided to the support rollers of the first group and the at least one staggered arranged support roller with a sufficient distance in Position conveying direction.
  • a central arrangement of the at least one staggered support roller or the second group of support rollers between the first groups of support rollers of successive support roller assemblies can also be provided that the first group of support rollers on the one hand and the at least one staggered support roller or the second group of support rollers of the same support roller assembly on the other hand are arranged on mutually separated and spaced support devices.
