Description

(1) The invention is explained in more detail below on the basis of preferred exemplary embodiments with reference to the accompanying drawings. In the figures:

(2) FIG. 1 shows a schematic sectional representation of a conveyor belt according to the invention,

(3) FIG. 2 shows a schematic sectional representation through a carrying roller station of a conveyor belt according to the invention formed as a tubular conveyor belt,

(4) FIG. 3 shows a schematic perspective sectional representation of a conveyor belt according to the invention formed as a tubular conveyor belt,

(5) FIG. 4 shows a further schematic perspective sectional representation through a conveyor belt according to the invention formed as a tubular conveyor belt, and

(6) FIG. 5 shows a schematic representation of a section through a conveyor belt according to the invention formed as a pouch conveyor belt.

(7) FIG. 1 shows a schematic sectional representation through a conveyor belt 100 along a transverse direction Y of the conveyor belt 100. The conveyor belt 100 has a belt body 10, which has a carrying-side cover sheet 11 and a running-side cover sheet 12, opposite from the carrying-side cover sheet. The material to be transported, not shown here, lies on the carrying-side cover sheet 11. Carrying rollers 210 for conveying the conveyor belt 100 in the conveying direction Q lie against the running-side cover sheet 12, as shown for example in FIG. 2.

(8) Arranged between the carrying-side cover sheet 11 and the running-side cover sheet 12 are a multiplicity of tension members 13, which can absorb tensile forces of the conveyor belt 100. In the case of the configuration shown here, the number of tension members 13 in this case decreases from the middle (zone E) of the belt body 10 to the belt edges (peripheral zones A, B) of the conveyor belt 100 or the belt body 10. Steel cables may be used for example as tension members 13.

(9) A profiling 14 is formed on the carrying-side cover sheet 11, the profiling 14 having transverse-strip profiling regions 15 and chevron profiling regions 16. The transverse-strip profiling regions 15 have a height H.sub.Q, which is greater than the height H.sub.C of the chevron profiling regions 16. The sectional representation in FIG. 1 reveals a transverse-strip profiling region 15 and a chevron profiling region 16 arranged in front of it. The chevron profiling region 16 shown in FIG. 1 has a number of individual web elements 17, which may take the form of so-called oblique-protuberance or herringbone patterning. The transverse-strip profiling region 15 shown in FIG. 1 also has a number of individual web elements 18. The chevron profiling regions 16 and the transverse-strip profiling regions 15 extend over the width of the region C of the carrying-side cover sheet 11 of the belt body 10 within the zone E. The chevron profiling regions 16 and the transverse-strip profiling regions 15 extend in a perpendicular direction Z away from the surface 21 of the carrying-side cover sheet 11. The width of the profiling region C is generally half to two thirds of the entire belt width. Consequently, the profiling region C is much smaller than the zone E.

(10) In FIG. 2, the conveyor belt 100 takes the form of a tubular conveyor belt, in that the peripheral zones A, B of the belt body 10 are arranged overlapping. As shown in FIG. 2, the conveyor belt 100 is arranged here in a carrying roller station 200, which has a multiplicity of carrying rollers 210 arranged distributed over the circumference of the conveyor belt 100.

(11) In FIG. 2 it can also be seen that, with the conveyor belt 100 formed as a tubular conveyor belt, the transverse-strip profiling regions 15 fill at least half, preferably two thirds, of the cross-sectional area of the conveyor belt 100 formed in a tubular manner. Not only the transverse-strip profiling region 15 that can be seen in FIG. 2 has a number of individual web elements 18 but also the chevron profiling region 16 that can be seen in FIG. 2 has a number of individual web elements 17. The tubular shaping of the conveyor belt 100 means that the individual web elements 18 arranged alongside one another of the transverse-strip profiling region 15 lie against one another or overlap, with the result that the transverse-strip profiling region 15 forms a closed separating wall over a large part of the width E of the carrying-side cover sheet 11.

(12) FIG. 3 shows a perspective schematic sectional representation of a conveyor belt 100. It can be seen in this representation of a section that, to increase its transverse stiffness, the belt body 10 has a number of fabric plies 22, which act as tension members and are separated by thick rubber layers 28, and a reinforcement 23, which may for example be formed as a fabric reinforcement or a steel reinforcement. In a rolled-together form of the conveyor belt 100, such as that shown in FIG. 3, both the reinforcement 23 and the fabric plies 22 separated by thick rubber layers 28 can ensure the transverse stiffness of the conveyor belt 100 for a long period of time, whereby it is possible in particular to prevent the conveyor belt 100 from collapsing. Polyester, polyamide, cotton or aramid may be used for example for the fabric plies 22. Fabric cords or steel cords, which are arranged transversely to the longitudinal direction X in the belt body 10, may be used for example as the reinforcement 23.

(13) In the representation in FIG. 3, a profiling 14 is likewise shown on the carrying-side cover sheet 11 of the belt body 10, the perspective representation revealing two chevron profiling regions 16 and one transverse-strip profiling region 15. The transverse-strip profiling region 15 shown in FIG. 3 has a web element 27, which extends continuously over a large part of the width E of the carrying-side cover sheet 11 and has a wave edge form.

(14) The chevron profiling regions 16, which are arranged in front of and behind the transverse-strip profiling region 15 in the longitudinal direction X of the conveyor belt 100, have in each case a number of web elements 17 in the form of oblique protuberances arranged diagonally in relation to the longitudinal direction X of the carrying-side cover sheet 11 and arranged in groups 24, each group 24 of web elements 17 forming a V shape with a tip 25 formed by two mutually adjacent web elements 17, the tip being aligned counter to a conveying direction Q of the conveyor belt 100. Apart from the two web elements 17 forming the tip 25, the individual web elements 17 are arranged spaced apart from one another. Arranged at the tip 25 is an additional web element 26, which extends in the longitudinal direction X of the carrying-side cover sheet 11, this additional web element 26 extending away from the tip 25 counter to the conveying direction Q of the conveyor belt 100. The chevron profiling regions 16 that can be seen in FIG. 3 have in each case a number of groups 24 of web elements 17 arranged diagonally in relation to the longitudinal direction X of the carrying-side cover sheet 11.

(15) FIG. 4 shows a representation of a conveyor belt 100 in which two transverse-strip profiling regions 15 and two chevron profiling regions 16 can be seen, these being arranged in an alternating manner, in that in the longitudinal direction X a chevron profiling region 16 is followed by a transverse-strip profiling region 15 and a transverse-strip profiling region 15 is followed again by a chevron profiling region 16, and the latter is again followed by a transverse-strip profiling region 15, this alternating arrangement of chevron profiling regions 16 and transverse-strip profiling regions 15 preferably extending over the entire length of the conveyor belt 100. The conveyor belt 100 shown in FIG. 4 differs substantially from the conveyor belt 100 shown in FIG. 3 in that, instead of the fabric plies 22 of the conveyor belt 100 shown in FIG. 3, in the case of the conveyor belt 100 shown in FIG. 4 tension members 13 in the form of steel cables running in the longitudinal direction X are arranged in the belt body 10.

(16) FIG. 5 shows a conveyor belt 100, which is formed as a pouch conveyor belt. The conveyor belt 100 has formed-on profiles on its belt body 10, in particular at the peripheral zones A, B of the belt body 10, tension members being formed into the profiles in the longitudinal direction of the conveyor belt 100. The conveyor belt 100 is held and guided between carrying rollers of a carrying roller station 200. The belt body 10 of the conveyor belt 100 takes the form of a pouch, here too both transverse-strip profiling regions 15 and chevron profiling regions 16 being formed on the carrying-side cover sheet 11 of the belt body 10. As a result of the sectional representation, one of this number of transverse-strip profiling regions 15 and one of this number of chevron profiling regions 16 can be seen in FIG. 5, the transverse-strip profiling region 15 being formed by a number of web elements 18 lying against one another or overlapping and the chevron profiling region 16 being formed by a number of web elements 17 substantially arranged spaced apart from one another.
