Description

 BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a self-generating feed roller using conveyor belt friction,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic power generator of a conveying roller using conveyor belt friction, and more particularly, to a conveyor belt having a plurality of conveying rollers for supporting upper and lower sides of a conveyor belt, When the conveying roller is driven by the friction, the self-generator accommodated in the conveying roller produces electricity. In addition, a conveyor belt which is capable of increasing the amount of electricity generated by installing a speed- Generator.

A self-generating device is a device that generates electricity by itself, and does not require energy input from the outside. In other words, it refers to a device that produces electric energy and supplies and consumes electric energy by itself. The self-generating device is attracting attention in terms of reduction of environmental pollution and cost reduction. Recently, it has been applied to a wide range of products ranging from shoes, bags, belts, flashlights, jump ropes, gates, and fishing rods. In addition, in industrial use, a conveyor belt, which is useful when conveying coal or heavy articles, is provided with a driving shaft pulley and a driven shaft pulley in an elliptical orbit, and a plurality of conveying rollers are supported in the conveying direction of the conveyor belt In addition, since the rotating conveying roller has a rotating structure, the self-generator is used by using the kinetic energy of the conveyor belt.

As another example thereof, as disclosed in Patent Registration No. 10-0892295, a technical structure thereof is provided with a generator having a stator and a rotor on the axis of a pressure roller for pressing the upper surface of the lower belt of the endless track type belt, And the stator and the rotor are interlocked together to generate electricity.

As described above, the pressure roller that rotates by pressing the lower belt of the endless track type belt rotates and is capable of producing electricity by a stator spaced apart from the rotor at one shaft connected to the pressure roller. The diameter of the pressure roller Since the diameter of the shaft is smaller, the electric power production can be increased by the increased rotational force.

However, since the lengths of the shafts coupled to the pressurizing roller and the opposite end portions are different from each other, a weight sticking phenomenon occurs in a long direction. Therefore, there is a problem that a support frame must be additionally installed on both axes to compensate for this.

In addition, it is necessary to extend the shaft to one side of the pressure roller in order to perform self-power generation, which is a very complicated structure.

Therefore, as disclosed in the patent application No. 10-1815566 filed by the present applicant, the technical structure is such that both ends of a plurality of conveying rollers for supporting the upper and lower sides of the conveying belt to prevent the belt from sagging, First and second bushings are fixedly coupled to inner circumferential portions of both side ends of a cylindrical member provided on the outer circumferential edge of the conveying roller, A rotating permanent magnet is disposed at one end of the bushing, and a stator having a coil wound around the core is disposed at a circumference spaced apart from the permanent magnet so that a power generating unit for generating electricity is disposed. And the stator is coupled to the end of the second central shaft by a key bolt.

Since the first and second central axes are of the same size as described above, there is no tendency for the cylindrical member to deviate toward one side when rotating, and there is no need for additional installation for supplementing it. Since the power generating unit is provided inside the cylindrical member, As shown in FIG.

However, the cylindrical member rotating by friction with the conveyor belt produces electric power by the coils wound around the permanent magnet interlocked with the first bushing by the rotation of the first bushing and the iron core core fixed to the permanent magnet, The permanent magnet rotates in the same direction in proportion to the rotational force, so that it can always produce a constant electricity.
