DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt conveyor, and more particularly to a belt conveyor having a twist conveying surface.

[0002]

2. Description of the Related Art A belt conveyor of this kind is shown in FIGS.
As shown in FIG. 3, the rollers 90, 90 are inclined in the opposite direction by the same angle (the rollers 90, 90 are moved along the center line L of the belt).
In the opposite direction with respect to the roller 90) and a belt 91 between the rollers 90, 90.
Is stretched by applying a certain amount of tension.
A meandering preventing device (not shown) is disposed on both sides of the belt 91 between the rollers 90, 90 so that the belt 1 does not meander.

[0003] Therefore, in this conveyor, the belt 9
Even if the conveying surface of the belt 91 is twisted, the belt 91 is prevented from meandering because the contact pressure between the belt 91 and the roller 90 in the axial direction of the roller 90 is balanced, and as a result, the position of the conveying surface of the belt 91 is reduced. There is no possibility that the surface rises or a large load acts on the meandering prevention device.

However, in response to the recent demands of the industry using a belt conveyor, if the rollers 90 are angled relative to each other with reference to a position deviated from the center line L of the belt, In this case, since the contact pressure between the belt 91 and the roller 90 in the axial direction of the roller 90 becomes unbalanced, the conveyance surface of the belt 91 is lifted and the meandering prevention tool is shortened.

[0005]

[SUMMARY OF THE INVENTION Therefore, in the present invention, rather difficulty leads to shortening of the conveying surface of the lifting and meandering preventing device of the belt regardless of the aspect of the twisting of the belt, and
An object of the present invention is to provide a belt conveyor having a twisted conveying surface that can convey an object even in a state where the object is inclined .

[0006]

In the belt conveyor having a twisted conveying surface according to the present invention, rollers (1) and (1) are arranged at a fixed interval, and one roller (1) is arranged with respect to the other roller. (1) is tilted up and down, and a belt (2) is stretched while being twisted between the rollers (1) and (1). The rollers (1) and (1) are arranged so that the belt (2) does not meander. In a belt conveyor in which meandering prevention devices (3) are arranged on both sides of the belt (2) between each other, the warp of the fabric constituting the belt (2) is formed of urethane elastic yarn, rubber yarn, or wooly nylon yarn. The belt (2) and the roller (1) whose transport surface is twisted by this
Citea so as to be smaller in the axial direction of the imbalance of the contact pressure roller (1) and is, on the belt (2)
Has a receiving member (2c) extending all around the belt longitudinal direction.
I have .

[0007] In the belt conveyor having a conveying surface twist the invention, the fabric is warp constituting the belt 2, urethane elastic yarn, rubber yarn, or because are constituted by woolly nylon yarn, smaller polyester filament yarn elongation Each roller 1 compared to the conventional belt constituted by
The imbalance of the contact pressure between the belt 2 and the roller 1 in the axial direction becomes smaller, so that the meandering of the belt 2 is suppressed. Therefore, it is possible to prevent a part of the conveying surface of the belt 2 from rising or to apply a large load to the meandering prevention device 3. The belt 2 has a belt length.
The transferred object is brought into contact with the receiving member 2c extending all around the hand direction.
Can be conveyed even in a state where is tilted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

This belt conveyer conveys the conveyed object H in an inclined posture on the rear side in the conveying direction as shown in FIG. 3, and conveys the conveyed object H in a horizontal posture on the front side in the conveying direction as shown in FIG. Basically, as shown in FIG. 1, a roller 1a, a roller 1b arranged at an interval from the roller 1a, and a belt 2 stretched between the rollers 1a and 1b, The belt 2 includes a meandering prevention device 3 for supporting both side edges, a driving device 4 for rotating the roller 1a, and a mount 5 on which the rollers 1a and 1b, the meandering prevention device 3 and the motor 40 are mounted. .

As shown in FIG. 2, the roller 1a is rotatably mounted on the gantry 5 via a bearing 10 in a horizontal posture.

The roller 1b is, as shown in FIGS. 2 and 3,
It is rotatably mounted in a posture inclined with respect to the gantry 5 via the bearing 10. In addition, as shown in FIG.
One end of the roller 1b and one end of the roller 1a are at the same level, and the other end of the roller 1b is at a higher level than the other end of the roller 1a.

As shown in FIGS. 3 and 5, the belt 2 has a cylindrical belt main body 2a open at both ends, a bead 2b fused to both end edges thereof, and a receiving member formed at one end side of the belt 2. 2c. Note that, in this conveyor, as shown in FIG.
Can be transported in a state where the posture is inclined.

Here, the belt main body 2a is formed by vulcanizing and bonding a thin rubber plate to a woven fabric, and the warp yarn (meaning the yarn in the longitudinal direction of the belt) of the woven fabric is formed of urethane elastic yarn. .

As shown in FIG. 5, the meandering prevention device 3 includes upper and lower fixing members 30 and 30 supported by the gantry 5 and rotating members 31 and 3 attached to each fixing member 30 in a horizontal C-shape.
The bead 2b of the belt 2 is movably held between the rotating bodies 31 and 31. As shown in FIG. 1, a plurality of the meandering preventing devices 3 are provided at a portion between the rollers 1a and 1b.

The drive unit 4 transmits the rotation of the motor 40 to the roller 1a via pulleys 41 and 42 and a flat belt 43 as shown in FIG.

Since the belt conveyor has the above-described configuration, as described above, the belt 2 is unlikely to float up and the meandering preventing device 3 to be short-lived regardless of the form of twist of the belt 2. It will be.

In the above-mentioned conveyor, the warp used for the belt 2 is made of urethane elastic yarn. However, the present invention is not limited to this, and rubber yarn and woolly nylon yarn can also be used.

[0018]

From the contents of the action described in the column of means for solving the problems according to the present invention, rather difficulty leads to shortening of the conveying surface of the lifting and meandering preventing device of the belt regardless of the aspect of the twisting of the belt, and Conveys objects even when they are tilted
A belt conveyor having a twistable conveying surface that can be provided.
