'' Curvaceous' wire mesh conveyor belt "

The invention is based on a conveyor belt system laid in curves with a wire mesh conveyor belt. Such wire mesh conveyor belts are curvilinear because they can be pushed together on the inner radius of the curve.

In the curves there are now tension-compression ratios, "which make the arrangement of devices necessary, which the curve-going, ensure proper guidance and movement of the conveyor belt * It is a matter of balancing radial support forces, the is arranged on the inner radius, in the middle of the belt or on the outer radius »These compensation and support arrangements either" work with sliding or rolling devices.

When arranging guide strips to absorb the radial forces in the curve are in known wire mesh conveyor belts on the Conveyor belt special guide elements arranged that grip behind the guide bar.

For rolling support, it is known to use the belt edges of the wire mesh conveyor belt to guide along a row of rollers fixedly arranged on the conveyor frame within the curve. The Edge guidance only punctiform, as the rollers arranged in the curve radius do not represent a continuous guide line. To the meeting only edge points of the wire mesh conveyor belts on these isolated rollers, since the wire mesh conveyor belts are not closed Form edge line. With such a curve in the middle of the belt or on the outer radius there are special support elements on the link belt

necessary. Instead of the rollers, you also have chains. Cable or belt drives used, which must however run synchronously in order to Differential speeds, and thereby to avoid wear. A chain, rope or belt drive running along with it also requires either a special hook edge on the outer radius or a special support edge on the central radius.

In the case of a curve on the inner radius, the chain, rope or Belt drive does not represent a section of a circular circumference, as the one here pieces of belt to be seen as tendons between the belt support rollers form a polygonal curve.

The object of the invention is to provide a curve guide for a normal Wire mesh conveyor belt to create a allows perfect guidance of the conveyor belt in the curve. To solve this problem it is proposed according to the invention that in outer curve area gears that go into the gaps of the Engage wire mesh, are arranged one behind the other in the transport direction. In a further embodiment of the invention, the teeth are the Gear wheels are conical, offset from one another, partly below and partly above the conveyor belt and with additional Provide counter rollers or low pressure strips. To solve the problem, the invention uses means which are in themselves taken from the general Mechanical engineering or conveyor technology are known. This is also true for the gears with conical flanks, the use of low-pressure strips and for gears above and below conveyor belts

Due to the inventive design of the curve guide, there are no special complex belt edges are required on the wire mesh conveyor belt. Furthermore, additional guide devices are on Wire mesh conveyor belt avoided.

An exemplary embodiment of the invention is shown in the drawing. It shows:

Figure 1 shows a conveyor belt system with a double curve and in the

Gears arranged in curves;

FIG. 2 a wire mesh conveyor belt with a welded edge

and schematically drawn teeth;

Figure 3 shows a part of a gear with a conical shape

the teeth; '

FIG. 4 shows a side view of FIG. 2;

Figure 5 a. Conveyor belt with toothed wheel and hold-down bar;

Figure 6 shows an arrangement according to Figure 5, but with a low

holding roller;

FIG. 7 shows a toothed wheel with an offset arrangement of the teeth

in side view and

FIG. 8 shows a section along the line I I in FIG.

FIG. 1 shows the arrangement of the gears 1 in the conveyor belt system and FIG. 2 shows the engagement of the teeth 2 in the spaces 3 of the conveyor belt links 4 of the conveyor belt 5.

The design of the teeth 2, in which at least one flank to the tooth tip runs conically, allows the tape to be guided in the curve, which not only compensates for the inward radial thrust; it also ensures that the tape runs properly in the area in which the entire Tape tension occurs within the curve. The teeth 2 engage in the spaces 3 of the links, as shown in Figures 2 to 4, and push them through the conical design of the face of the teeth, against the radial thrust directed towards the inside of the curve outside to a degree that is given by the shape of the tooth 2 is. \

In the example shown here, the teeth 2 are on the gear offset, as shown in Figures 7 and 8, arranged by one to achieve secure engagement in every belt division.

It is not possible for the belt 5 to slip inwards. To also In the event of exceptional stresses, the belt will slip 5 to exclude from the teeth 2, the gears can partly below, are partly arranged above the belt 5. Furthermore, a mating wheel 6 can also be assigned to the gear wheel 1 or in the area of the gears 2 a low pressure bar 7 are arranged as this Figures 5 and 6 show.

The direction of tape travel is marked with the number 8. That The degree of conicity of the teeth 2 determines the size of the radially outwardly directed support force and thus the curve-correct movement of the belt 5. Within the respective curve, several of these Gears 1 arranged on the respective curve outside sens side. The distance between the gears 1 can be a multiple of the belt division. at particularly light wire belts, which are generally moved in a sliding manner, all gears 1 can be arranged below the belt 5. In In this case, only the tips of the teeth protrude from the plane of the band.
