Abstract

(57) [Abstract] [Purpose] To reduce the noise caused by the movement of the conveyed objects on the rollers for the roller conveyor. [Structure] An anti-vibration material is arranged inside a roller for a roller conveyor.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-vibration roller for a roller conveyor.

[0002]

[Prior art]

 As is well known, the roller conveyor has rollers arranged at regular intervals, and an object to be conveyed moves on a roller to convey it to a predetermined position. The roller is generally made of steel or cast metal when the object to be conveyed is heavy, and is made of non-ferrous metal such as aluminum when the object is relatively lightweight and small such as a parcel.

However, each of the rollers is made hollow in terms of weight saving, cost reduction, and the like. When a conveyed object moves on such a roller, the contact movement noise between the roller and the conveyed object, and the roller. Are arranged at regular intervals, and a collision sound is generated when the tip of the conveyed object collides with the top of the roller when the conveyed object moves.

[0004]

[Problems to be solved by the device]

 As described above, the present invention can significantly reduce the contact movement noise generated when the conveyed object comes into contact with the roller and the collision noise caused when the tip of the conveyed object collides with the roller top when the conveyed object moves. It is intended to provide an anti-vibration roller for use.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, in the present invention, a vibration isolator is arranged inside a roller for a roller conveyor. That is, in the present invention, the vibration damping material is arranged on the inner wall of the roller to reduce the contact movement noise and the collision noise. The anti-vibration material is arranged, for example, on the inside of the body or on the inner surface of the body and both side walls.

As a mode of arranging the vibration isolator inside the roller as described above, for example, the vibration proof material is arranged in a layer of several millimeters to several tens of millimeters via a binder, that is, a layer is formed depending on the degree of noise generation. It determines the thickness. If the object to be conveyed is, for example, made of metal and is large and noisy, the roller hollow part is filled with a vibration isolator, and the vibration isolator is disposed substantially inside the roller, and the hollow part is Noise can be significantly reduced by maximizing the layer thickness of the vibration isolator as it is filled. Next, as the vibration-proof material, for example, urethane is suitable, but other thermoplastic resin or thermosetting resin can be used.

Although the same effect can be obtained by disposing the vibration isolator outside the rollers, it is disadvantageous because the vibration isolator is worn out due to the moving friction of the conveyed object and the vibration isolator is frequently replaced. In addition, if the transported object is a high temperature object, the vibration isolator will be greatly worn, which is extremely unfavorable for maintenance.

[0008] Thus, compared to the conventional case where the conveyor is composed of rollers in which the anti-vibration material is not arranged inside the roller, when the conveyor is composed of the rollers according to the present invention as described above, noise can be reduced by about 20%. Is.

【Example】

 The present invention will now be described in detail with reference to the illustrated embodiment. [Embodiment 1] In FIG. 1, a vibration isolator 4 is arranged inside a body 2 of a roller 1 for a roller conveyor and both side walls 3 and 3a of the roller 1 via a binder. In the figure, 5 is a hollow portion of the roller, and 6 is a roller shaft. [Embodiment 2] In FIG. 2, the hollow portion 5 of the roller 1 including the body portion 2 of the roller 1 for the roller conveyor and the side walls 3 and 3a of the roller 1 is filled with the vibration isolator 4 to substantially prevent the roller 1 from moving. A vibration isolator 4 is arranged inside the body 2 and the side walls 3 and 3a of the roller 1. In the figure, 6 is a roller shaft.

[0010]

[Effect of device]

 As is clear from the above description, according to the present invention, noise accompanying the movement (conveyance) of the conveyed object on the roller conveyor can be significantly reduced. Further, since the anti-vibration roller according to the present invention can maintain the anti-vibration function until the life of the roller, excellent effects such as extremely advantageous in terms of cost can be obtained.
