DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor device, and more particularly to a conveyor device used in a portion where a conveying path is bent in the middle.

[0002]

2. Description of the Related Art Conventionally, as this type of conveyor device,
In order to join between two belt conveyor devices arranged at right angles, a corner relay conveyor device as shown in FIG. 7 is used. In this conveyor device, the endless belt-shaped conveyor belt 41 is bent at 45 places by two trapezoidal sliding plates (not shown) at 45 degrees each, and further two rollers 4 are formed.
2, the belt-shaped transport belt 41 is turned up and down.

[0003] The conveyor device constructed as described above is arranged between two belt conveyor devices 43 and 44 arranged at right angles, and a conveyed object (not shown) sent from one of the belt conveyor devices 43. Is received by the trapezoidal transport section 41a of the conveyor device and sent out to the other belt conveyor device 44. In this case, the belt-shaped transport belt 41 is sequentially circulated in the arrow direction.

The trapezoidal return portion 41b at the lower stage of the belt-shaped transport belt 41 is usually disposed directly below the transport portion 41a. However, in order to facilitate understanding of the structure of the conveyor device, the position of the return portion 41b is conveniently set. Has been shifted.

However, in the above-mentioned conveyor device, the belt-shaped transport belt 41 is bent at 45 degrees at four locations and further folded up and down by the rollers 42, so that the structure becomes complicated, the cost becomes high, and the failure occurs. It will be easier.

In order to solve this problem, a plurality of cord-shaped transport belts are arranged so as to be trapezoidal in plan view,
Alternatively, there is a technique in which a plurality of cord-like transport belts are arranged so as to be oblique in plan view, and the plurality of cord-like transport belts are circulated in the same direction at the same speed.

In the case of this technique, if a plurality of cord-like conveyor belts are arranged in a trapezoidal shape, they can be used as a corner relay conveyor device for connecting between two belt conveyor devices arranged at right angles. By arranging a plurality of cord-shaped conveyor belts so as to be oblique, the conveyor belt can be used as a conveyor system for connecting two belt conveyor systems whose conveyance directions are substantially parallel and whose center axes are shifted from each other. The above technology is described in detail in the specification of Japanese Patent Application No. 7-125422 filed by the present applicant.

In the case where a plurality of cord-like conveyor belts are arranged in an oblique manner, as shown in FIG. 6, a plurality of conveyed objects sent from one belt conveyor 33 in the direction of arrow B are transferred. Belt conveyor device in which two string-shaped conveyor belts are arranged in an oblique manner and conveyed in the directions of arrows C and D, respectively, and the conveying directions are substantially parallel and the central axes are shifted from each other. 34 and 35. The belt conveyor devices 34 and 35 convey the conveyed objects in the directions of arrows E and F, respectively.

[0009]

In the above-mentioned conventional conveyor apparatus, in order to simplify its structure, to reduce the cost and to make it difficult to break down, a plurality of cord-shaped conveyor belts are trapezoidal or oblique in plan view. And circulate at the same speed in the same direction.

[0010] However, in order to connect a plurality of belt conveyor devices, the structure must be set in advance in accordance with the bent portion. Therefore, each time the transport path is changed, a relay conveyor device is manufactured in accordance with the arrangement. There must be.

For example, in order to connect two belt conveyors, whose transport directions are almost parallel to each other, to a belt conveyor for feeding an object to be transported, two relay conveyors having different transport directions are required. In particular, when the conveyance in two conveyance directions is performed in a time-division manner, one is moving and the other is stopped, but still requires two relay conveyor devices.
