Description

Anti-meandering Roller of Belt conveyer

The present invention relates to a meander prevention roller of a belt conveyor, and in particular, a belt which is installed at both ends of the width of the belt in a direction entering the drive roller and the return roller so that the belt of the belt conveyor rotates forward. It relates to a meander prevention roller of a conveyor.

Conveyors are widely used for transportation of parts, transportation of semi-finished products, transportation of coal, ore and cargo in mines and ports, and transportation of soil and sand in construction sites. At present, conveyors are used not only for the purpose of conveyance, but also for workbenches moving in conjunction with workers, forming the basis for mass production in the factory. The technology related to these conveyors has been further developed, such as a transfer machine that can install a special machine on the conveyor to perform the operation while moving the special device by the conveyor.

On the other hand, such conveyors include belt conveyors, screw conveyors, bucket conveyors, air conveyors, chain conveyors, roller conveyors, trolley conveyors, and fluid conveyors, among which the most representative conveyors are belt conveyors.

1 is a longitudinal cross-sectional view showing the configuration of a belt conveyor according to the prior art, Figure 2 is a cross-sectional view showing a guide roller of the belt conveyor shown in FIG.

As shown in FIG. 1, the belt conveyor 10 is an apparatus for continuously carrying an object on the upper surface of the upstream belt 20H while orbitally rotating the endless belt 20. Here, the material used as the belt 20 is rubber, fabric, wire mesh, steel sheet, and the like, among which the rubber belt is most used.

Such a belt conveyor has an endless belt 20, a driving roller 30 which is driven in contact with the inner surface of the belt 20, and an upstream belt 20H in contact with the inner surface of the belt 20. 20L) or the downstream roller (20L) to the upstream belt (20H) conversion roller 31 and the upstream belt (20H) and downstream belt (20L) is located on the bottom surface to prevent sagging of the belt 20 Idle rotating self-aligning rollers 33 are included.

As shown in FIG. 2, a plurality of guide rollers 35 are disposed along the longitudinal direction of the belt 20 at both ends of the width of the belt 20. The guide roller 35 is guided so that the belt 20 can be rotated in a forward direction, that is, in the direction of the driving roller 30 in the switching roller 31 or in the direction of the driving roller 30 in the switching roller 31. It is a roller.

Such a guide roller 35 is located close to both ends of the width of the belt 20, so that the belt 20 and the guide roller 35 abut when the belt 20 tries to meander. At this time, the guide roller 35 in contact with the advancing belt 20 rotates by friction with the belt 20 to prevent meandering of the belt 20.

However, the conventional guide roller 35 for preventing meandering of the belt 20 is possible only when the meandering of the belt occurs relatively small. If the meandering of the belt occurs badly, the belt 20 may ride over the guide roller 35 and leave the guide roller 35. In this case, the operator stops the peripheral devices for driving the belt conveyor 10 and the peripheral parts which are located in the periphery of the belt conveyor 10 and process the unfinished products moving along the belt conveyor, and enter maintenance work. In addition, the detached belt is damaged while hitting the peripheral device has a disadvantage of shortening the life of the belt.

In particular, when the belt 20 meanders when entering the driving roller 30 and the switching roller 31, the belt 20 proceeds along the outer surfaces of the driving roller 30 and the switching roller 31 more severely. Eventually, the belt 20 will deviate from the orbit. As such, the belt 20 correctly entering the driving roller 30 and the switching roller 31 becomes an important factor in determining the orbital rotation.

However, as described above, the conventional guide roller is installed in front of the driving roller and the switching roller has an unsafe structure to prevent the meandering of the belt.

The present invention has been proposed to solve the problems of the prior art as described above, is located in front of the drive belt and the conversion belt in order to prevent the belt rotating orbiting by the drive belt and the conversion belt in the track deviation. It is an object of the present invention to provide a belt conveyor meandering roller for inducing the orbital rotation of the belt by safely supporting the belt entering the drive belt and the conversion belt.
