BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lagging member mounting structure for a conveyor belt.

[0002]

2. Description of the Related Art Conventionally, a lagging material for protecting the surface of a conveyor belt or the like has been attached to a material constituting the surface or a material such as a filler which separately covers the surface, and the lagging material outside the material. The embedding is performed so that the surface is flush with the outer surface of the above-mentioned material, and in order to prevent the lagging material from peeling off or falling off, the embedding part of the lagging material is provided with irregularities. .

[0003]

However, even when unevenness is provided in the above-mentioned buried portion, the effect of preventing the peeling and falling of the lagging material is ultimately reduced, and the strength of the conveyor belt surface or the filler material and the lagging material Since it depends on the adhesive strength, it is impossible to completely prevent the risk of peeling or dropping of the lagging material, especially in a conveyor belt or the like which is repeatedly subjected to a bending action.

Further, it takes a huge amount of work to lay out a large number of lagging materials on the surface of the conveyor belt in a regulated manner, which hinders the improvement of the burying work efficiency.

[0005]

In view of the above, in the present invention, a large number of rugging materials are buried in the surface of a conveyor belt so as to be flush with the surface, and a substantially rectangular protrusion is formed on the back surface of the lagging material. The protrusion is formed by extending the lower front and rear side edges and the lower left and right side edges to the outside, respectively, to form the extension portion at the lower portion of the protrusion portion, and by the extension portion, the lagging material and the extension portion are formed. And an engaging concave portion that opens laterally outwardly are formed between them, and on the other hand, the cord-shaped bodies are arranged in the conveyor belt so as to intersect with each other in a lattice shape, and the grid portion of the cord-shaped bodies is lagging. The protrusions of the material are positioned, and the lattice-shaped cords are engaged with the engaging recesses of the protrusions from the outside, so that each lagging material is fixed in an array by the lattice-shaped cords. To provide a structure for mounting lagging material on a conveyor belt A.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, (A) is a conveyor belt, and the lagging material (B) according to the present invention is embedded in the surface layer (3) of the conveyor belt (A). Exposes its surface (1) flush with the surface (2) of the conveyor belt (A).

As shown in FIGS. 1 to 3, the lagging material (B) is formed of a ceramic material into a substantially rectangular plate shape, and a substantially rectangular protrusion (7) is formed on the back surface of the lagging material (B). To form
The lugging material is formed by forming outwardly extending portions (8), (8), (8), (8) from the front, rear, left and right side edges of the lower end of the protruding portion (7), respectively.
Between the back surface of (B) and the extended portions (8), (8), (8), (8), engaging recesses (9) as insertion portions (D) parallel to the front-rear direction and the left-right direction, respectively. ), (9), (9), (9) are formed.

As the cord-like body (C), a nylon cord, a steel wire or the like which has appropriate flexibility and tensile strength and has good adhesion to the material of the conveyor belt surface layer (3) is used.

Four cords (C), (C), (C), and (C), which are vertically and horizontally inserted through the engaging recesses (9) of the lagging material (B) in the front-rear direction and the left-right direction, respectively. By engaging the lagging material (B) from all sides by engaging it from the outside, the lagging material (B) is fixed, and the lagging material (B) is fixed in this way. The mats are formed into a single mat by regularly connecting them vertically and horizontally at regular intervals.

A large number of lagging materials connected as described above
(B) is able to maintain a regular arrangement because it can be fixed vertically and horizontally by a total of four cords (C), (C), (C), (C).

A large number of lagging materials (B) thus connected in a regular arrangement are embedded in the surface layer (3) of the conveyor belt. As described above, the lagging material (B) is a cord-shaped body (C). Since the position is fixed by), the position does not shift during the above burying work and during the curing process of the surface layer (3), and the burying work is completed with the first regular arrangement, Can improve the finish.

To embed the lagging material (B),
The lagging material (B) can be directly embedded in the surface layer of the conveyor belt, or the lagging material (B) can be embedded on the surface of the belt using a filler.

In this way, the lagging material (B) is not only adhered to the surface of the conveyor belt due to the adhesive force with the surface layer (3) of the conveyor belt, but also the surface layer (3) together with the lagging material (B). The string-like body (C) embedded in the () can strongly prevent peeling and dropping from the surface layer (3).

[0015]

[Effect] According to the present invention, the following effects can be obtained.

That is, a substantially rectangular projecting portion is formed on the back surface of the lagging material, and the lower front and rear side edges and the lower left and right side edges of the projecting portion are respectively extended outward and extend to the lower portion of the projecting portion. And the engaging recesses that open laterally outward are formed between the lagging material and the extending portions, while the cords are arranged in a grid pattern in the conveyor belt. So that the protrusions of the lagging material are located in the lattice portion of the string-like body and the lattice-like string-like body engages with the engaging recesses of the protrusion from the outside. Since each lagging material is fixed in an array with a lattice-shaped string, each lagging material can be regularly embedded in a stable posture in a well-balanced front-back and left-right direction. It is possible to ensure the prevention of peeling and dropping.

Further, a large number of lagging materials are connected to each other in a blind or mat shape by using a string-like body before being attached to the surface of the conveyor belt, and the plurality of lagging materials thus connected are once Since it can be placed and buried on the surface of the conveyor belt, it is possible to bury the regularly arranged lagging material with a small number of steps,
There is an effect that the finish of the product and the work efficiency can be improved.
