Description

[Detailed description of the invention] The present invention relates to the improvement of a soundproof roll, and is particularly designed to prevent noise between the conveyed object and the roll and damage to the conveyed object during conveyance as a conveyor roll for conveying heavy objects. This relates to soundproofing rolls.

For example, in steel factories, etc., table rolls with hollow steel rolls are generally used to transport heavy objects such as steel plates, shaped steel, etc. There were problems such as significantly deteriorating the environment and damaging the transported objects.

Therefore, in order to solve the above-mentioned problems, the following methods have been used: (a) Rubber or plastic, which has a noise-repelling effect due to its cushioning and sound-absorbing properties, is attached to the roll body using adhesive or vulcanization. Adhesive directly.

(b) A substance similar to that described above is adhered to the outer circumferential surface of a sleeve of a certain length, and a large number of these sleeves are arranged and fixed on a roll in rows.

Other methods are being tried.

However, the materials with cushioning and sound-absorbing properties such as rubber and plastic used to obtain these soundproofing effects have low strength, and may cause local damage due to edge cuts caused by collisions with the edges of the transported object. There is a problem that it is damaged and cannot withstand long-term use.

In order to solve this problem, attempts have been made to attach a thin iron plate to the outer circumferential surface of the above-mentioned material, thereby protecting the outer circumferential surface of the roll and extending its life. At present, there are still problems, such as not only the prevention effect being halved, but also the protective thin iron plate becoming dented due to collision with the transported object.

The present invention was obtained as a result of studies to solve the above-mentioned problems.

Therefore, an object of the present invention is to provide an excellent soundproof roll that can significantly strengthen the surface of the roll without impeding the noise prevention effect by devising the surface structure of the roll.

In other words, in the present invention, wire ropes are brought into contact with each other and wound in a spiral shape on the outer peripheral surface of a roll core metal via a flexible sound-absorbing layer such as rubber, and these are integrally vulcanized and bonded. The gist of this is a soundproof roll that is characterized by:

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

FIG. 1 is an explanatory partially cutaway front view showing a soundproof roll according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view showing the main part of the same, that is, the state of adhesion between the sound-absorbing layer and the wire rope. .

In the figure, E is a soundproof roll made of an embodiment of the present invention.
By bringing wire ropes 3 into contact with each other and winding them in a spiral shape on the outer peripheral surface of the roll core metal 1 via a flexible sound-absorbing layer 2 such as rubber, the wire ropes 3 are integrally vulcanized and bonded. It is configured.

Therefore, when an object is conveyed onto the soundproof roll E, the wire rope 3, which is originally flexible, bends and absorbs a part of the collision energy, and then the wire rope 3
The flexible sound-absorbing layer 2 on the lower side is greatly bent,
It can absorb large amounts of energy.

As a result, it is possible to prevent the generation of noise due to a collision between the conveyed object and the soundproof roll E, and it is also possible to absorb the collision energy.

Also, is the wire rope 3 that comes into direct contact with the transported object covered with a cushioning and sound absorbing layer such as rubber? ζSince it has significantly greater strength compared to the conventional method 1, even if a sharp part such as the edge of the conveyed object collides with it, the edge will not be cut like in the conventional method 1. Of course, there is also extremely little wear and tear, and therefore the lifespan can be significantly extended compared to conventional ones.

Furthermore, in the present invention, the wire rope 3 has a buffer sound absorbing layer 2.
Because the wire ropes 3 are wound tightly around the outer periphery of the wire in a spiral shape, in other words, the wire ropes 3 are brought into contact with each other and the objects to be transported are heavy and have a large width, such as Lm steel, H-shaped steel, or bar material. Even if the member is small in size and has a sharp peripheral edge, there is no risk that it will directly collide with the soft buffering and sound absorbing layer 2, and it also reliably prevents the wire rope 3 from shifting sideways due to the collision of the conveyed object. can do.

Therefore, no matter what cross-sectional shape the object to be transported is transported, the soundproofing effect and the buffering effect can be maintained for a long period of time.

In addition, the buffer sound absorbing layer 2, wire rope 3, and roll core 1 are integrally vulcanized and bonded. Compared to the case where each component is bonded using an adhesive, the adhesive strength can be greatly improved, the durability can be improved, and the life of the soundproof roll E can be further extended.

Next, a method for manufacturing the soundproof roll E described above will be briefly described.

First, the constituent members of the buffer sound absorbing layer 2 made of unvulcanized rubber are wound around the outer circumferential surface of the roll core metal 1, and then the wire ropes 3 are brought into contact with the outer circumferential surfaces of the constituent members of the buffer sound absorbing layer 2. The buffer sound absorbing layer 2, the wire rope 3 and the roll core bar 1 are wound in a spiral shape and fixed at both ends to the constituent members of the buffer sound absorbing layer 2, and then heated and pressurized to vulcanize. It is possible to obtain a soundproof roll E that integrates the following.

As described above, the present invention involves winding wire ropes in a spiral shape by bringing them into contact with each other through a flexible sound-absorbing layer such as rubber, on the outer peripheral surface of a roll core metal, and then integrally winding the wire ropes. Since it is constructed by bonding with sulfur, it has the following effects.

In other words, (1) the wire rope that comes into direct contact with the conveyed object has significantly greater strength than a shock absorbing layer such as rubber, so even if a sharp part such as the end of the conveyed object collides with it, , unlike the conventional type, it is not subject to edge cutting, and wear is extremely low, so the service life can be significantly extended compared to the conventional type.

(2) Furthermore, in the present invention, since the wire rope is wound spirally around the outer periphery of the buffer sound-absorbing layer, that is, with the wire ropes in contact with each other, the conveyed object can be
For example, even if the material is heavy, has a small width, and has a sharp edge, such as an L-shaped steel, H-shaped steel, or a bar, there is no risk that it will directly collide with the soft buffering and sound-absorbing layer. It is possible to reliably prevent the wire rope from shifting sideways due to a collision with the transported object.

Therefore, no matter what cross-sectional shape the object to be transported is transported, the soundproofing effect and the buffering effect can be maintained for a long period of time.

(3) Furthermore, since the sound absorbing layer, wire rope, and roll core are integrally vulcanized and bonded, the adhesive strength is greatly improved compared to when each component is bonded using an adhesive. This makes it possible to improve durability and further extend the life of the soundproof roll.
