[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved conveyor belt and a curved conveyor.

[0002]

2. Description of the Related Art As a curved conveyor, for example, a conveyor belt is stretched between a pair of taper rollers, but in order to prevent the conveyor belt from moving inward against centripetal force, the taper rollers are In between, as shown in FIG. 5, a large number of holders 3 are arranged outside the conveyor belt, and the bead material 21 provided on the entire outer peripheral edge of the belt body 20 is supported by the rotating bodies 31, 32, 33 of these holders 3. I am trying to do it.

The above-mentioned conveyor belt 2 is shown in FIGS.
As shown in FIG. 2, the belt body 20 and the bead material 21 made of an elastic synthetic resin composed of a thin plate portion 21a and a thick portion 21b connected to the belt body 21 are provided. 6, the thin plate portion 21b is sewn to a portion serving as an outer edge of the belt body 20 (the sewn portion is indicated by N).

However, in the conventional conveyor belt, as shown in FIG. 6, since the pitch line of only the belt body 20 and the positions of the thick line portion 21b and the pitch line PL of the belt body 20 are greatly different, At the belt portion wound around the taper roller 1 (see FIG. 7), slippage occurs between the belt body 20 and the thick portion 21b. Further, the slip causes a problem that abrasion powder is generated from the belt body 20 and the bead material 21 and the life of the conveyor is shortened.

[0005]

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a curved conveyor belt and a curved conveyor in which almost no abrasion powder is generated from the belt body or the bead material and the excellent conveyor life can be realized. .

[0006]

The curved conveyor belt according to the present invention has a bead member 21 in which a thick portion 21b of the bead member 21 is projected outward from the outer peripheral edge of the belt body 20.
The thin portion 21a is sewn to the outer peripheral portion of the belt body 20.

Further, in the curved conveyor belt of the present invention, the thin portion 21a of the bead material 21 is made to protrude inward from the inner peripheral edge of the belt body 20 so that the thin portion 21a of the bead material 21 becomes It is made by sewing to the part.

In the curve conveyor of the present invention, the belt main body 20 of the above-mentioned curve conveyor belt is stretched between the rotating rollers arranged at a predetermined angular interval, and the curve main body 20 is arranged at the inner fixing portion or the outer fixing portion of the conveyor. The thick portion 21b is sandwiched by the upper and lower rotating bodies to prevent the curved conveyor belt from moving inward.

[0009]

The present invention operates as follows.

In this curved conveyor, since there is no portion of the belt main body 20 corresponding to the thick portion 21b of the bead material 21, the position of the pitch line which is in contact with the rotating roller is very different from the pitch line of only the belt main body 20. Only the thin portion 21a is left.

Therefore, of course, no slip occurs between the belt body 20 and the thick portion 21b, and on the other hand, almost no slip occurs between the belt body 20 and the thin portion 21a.
