Abstract

(57) [Abstract] [Purpose] A conveyor belt in which a large number of ceramic chips are fixed in an embedded state on the conveying surface prevents slipping of the conveyed object and enables smooth conveyance. [Construction] In a conveyor belt 10 in which a large number of ceramic chips 20 are fixed to a conveying surface with their surfaces exposed, concave portions 28 or convex portions are provided on the surfaces of the ceramic chips 20.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a conveyor belt in which a large number of ceramic chips are fixed to a transfer surface.

[0002]

[Background of the invention]

 As a conveyor belt, as shown in FIGS. 4 (A) and 4 (B), a large number of ceramic chips 102 are arranged on the conveying surface of the rubber belt main body 100, and the ceramic chips 102 are exposed with the surface exposed. It is known that it is fixedly embedded in 100.

Here, the ceramic chips 102 are densely arranged in the width direction and the longitudinal direction with a minimum interval so that the exposed surface of the rubber belt main body 100 is reduced as much as possible.

In this ceramic chip burying conveyor belt 104, the ceramic chip 102 imparts heat resistance and wear resistance to the conveying surface, and conveys a hard conveyed object at a high temperature of about 150 ° C., such as coke in a steel mill. Can be suitably used as

[0005]

[Problems to be solved by the device]

 By the way, in the case of the conveyor belt 104 in which such ceramic chips are embedded, the coefficient of friction of the conveying surface is remarkably lower than that of a normal rubber belt or the like. Therefore, for example, such a conveyor belt 104 is as shown in FIG. 4 (C). When used in a tilted manner, there are problems that the transported object is likely to slip on the conveyor belt 104, smooth transportation cannot be performed, and that steeply inclined transportation similar to a general rubber belt is substantially difficult.

[0006]

[Means for Solving the Problems] The present invention has been made to solve such problems, and the gist thereof is to fix a large number of ceramic chips to the conveying surface of a belt in a state where the surface is exposed. In the conveyor belt of another form, a concave portion or a convex portion is provided on the surface of the ceramic chips.

[0007]

[Action and effect of the device]

 In the conveyor belt of the present invention, the concave or convex portion provided on the surface of the ceramic chip suppresses the slip of the conveyed product on the conveying surface.

Therefore, by using the conveyor belt of the present invention, it is possible to smoothly convey a conveyed object, and it is possible to perform a steep inclination conveyance like a general rubber belt.

Although the concave portion or the convex portion can have various shapes, it is preferable that the concave portion or the convex portion extends in a direction perpendicular to the conveying direction of the conveyor belt.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, 10 is a conveyor belt and 12 is a rubber belt main body. The rubber belt body 12 includes a reinforcing layer 14 made of a plurality of canvas cloths, a lower cover rubber layer 16 and an upper cover rubber layer 18.

A large number of ceramic chips (for example, alumina ceramic chips) 20 are arranged in a predetermined array with a minute gap on the upper surface serving as the conveying surface of the conveyor belt 10, and one diagonal line thereof is the width direction of the conveyor belt 10. They are lined up in the same orientation.

As shown in FIG. 1B, these ceramic chips 20 are embedded inside the upper cover rubber layer 18 with their front surfaces exposed, and are fixed by an adhesive.

In this example, the ceramic chips 20 are embedded over the width L = 1200 mm of the conveyor belt 10 and the width l = 800 mm.

As shown in FIG. 2, the ceramic chip 20 has a square planar shape and has openings 22 formed on the back surface side. The openings 22 communicate with each other through communication holes 24 inside the ceramic chip 20. Has been.

The opening 22 and the communication hole 24 are also communicated with a small hole 26 formed on the surface of the ceramic chip 20.

The opening 22 and the communication hole 24 allow a rubber material to enter the inside when the ceramic chip 20 and the rubber belt body 12 are integrally molded, thereby strengthening the bonding force between the ceramic chip 20 and the rubber belt body 12. However, it is for preventing the ceramic chip 20 from being detached when the belt is used.

Further, the small hole 26 on the surface side of the ceramic chip 20 is for bleeding air when the rubber material flows into the chip 20 through the opening 22.

Grooves 28 are formed on the exposed surface of the ceramic chip 20 along diagonal lines extending in the width direction of the conveyor belt 10.

In this example, the groove 28 is formed with a depth a = 1 to 2 mm and a width b = 3 to 20 mm.

The ceramic chip 20 has a side length c of 25 mm and a thickness d of 11 mm or less, and a thickness e of the portion between the bottom surface of the groove 28 and the communication hole 24 is 3 mm or more.

In the case of the conveyor belt 10 of this example, a groove 28 having a predetermined depth extending in the width direction of the belt is formed on the surface of the ceramic chips 20 arranged on the upper surface of the belt, and the conveyed object is formed by this groove 28. Is effectively prevented from slipping.

Therefore, it is possible to smoothly convey the conveyed object, and it is also possible to perform the steeply inclined conveyance similar to a general rubber belt.

By the way, in the case of the conveyor belt formed by burying the ceramic chips having no groove 28 as described above, the angle at which the inclined conveyance is possible is 10 to 15 degrees, but in the case of the conveyor belt 10 of this example, it is 15 to 15. Inclination conveyance up to 25 degrees is possible.

It should be noted that the above-described exemplified form of the ceramic chip 20 is merely one example, and in the present invention, the form of the ceramic chip can be various other forms.

FIG. 3 shows an example thereof. The ceramic chip 30 of FIG. 3 (a) is provided with a ridge 32 extending along the diagonal direction and having a width f = 10 mm and a length g = 20 mm, and the ceramic chip 34 shown in (b). 2 has a form in which the groove 28 shown in FIG.

In addition to this, the present invention allows the shape of such a ceramic chip to be another shape, and it is also possible to use a ceramic material other than the above example, which is outside the scope of the invention. It is possible to configure in a form in which various changes are made based on the knowledge of those skilled in the art within the range not to do.
