Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a round conveyor belt conveying device, and more particularly, it can reliably transfer from a round conveyor belt to a feed conveyor belt even when conveying small boxes, bricks, tiles, and the like. The present invention relates to a round conveyor belt transport device that can be used and that reduces noise during transport.

2. Description of the Related Art Belt conveyors are widely used to convey various articles, but they are not always required to convey a conveyed article in a linear direction but may be conveyed in a curved direction. As this conveyor device, there is known, for example, a structure in which a conical endless conveyor belt is stretched between two tapered end rollers pivotally supported by curved inner and outer frame members. However, since such a conical endless conveyor belt tends to be biased toward the center during traveling due to its nature, a guide device for preventing it is required, and various measures have been taken conventionally. It was

For example, a typical example thereof is a method in which rotatable rollers are mounted on the outer peripheral portion of the conveyor belt at a predetermined interval and the rollers of the belt are brought into contact with a protruding guide portion, or a conveyor belt. It was a method of mounting the outer peripheral part of a chain to a rotationally driven chain and running the chain on a fixed track.

Further, as disclosed in Japanese Utility Model Laid-Open No. 56-10413, a U-shaped guide member having a pair of guide portions and a mounting portion is provided on the outer circumference of the conveyor belt over the entire circumference of the belt ear portion. It has a structure in which a holding roller that supports mounting and tension is brought into contact with a pair of guide portions.

[0005]

However, in the conventional conveying device using two tapered end rollers, between the round conveyor belt and the feed conveyor belt, particularly on the side of the tapered end roller having a large diameter. The space between adjacent members has increased, and small boxes, bricks,
It was not possible to reliably transfer small articles such as tiles, and a transfer roller or plate was interposed between them.

Further, in a guide device using rollers having the same diameter as the end rollers and using a chain, the chain and the conveyor belt are connected via an interfering material such as a rope or a spring. There was a problem that the movement and that of the conveyor belt could not be synchronized. In addition, the connecting portion between the conveyor belt and the chain is likely to be cracked due to the large tension. Moreover, the chain drive causes a lot of noise and requires refueling.

Further, in the conveying device disclosed in Japanese Utility Model Laid-Open No. 56-10413, when uneven wear occurs in a pair of upper and lower guide members that come into contact with a holding roller, the vertical direction of the belt is unbalanced, resulting in a guide member. It appears as a downward sloping phenomenon or a upward leaping phenomenon. This is because the guide member comes into contact with the frame, leading to wear of the guide member.

The present invention solves such a problem, and in particular, a round conveyor belt which can reliably transfer a small conveyed article to another conveyor belt and which reduces noise during conveyance. It is an object of the present invention to provide a carrier device of the above.

[0009]

That is, a feature of the present invention is that a conical conveyor belt in which both ends of a belt-shaped belt are joined is stretched around end pulleys arranged at a predetermined angle, In a conveyor of a round conveyor belt, which is designed to prevent inward bias when the belt is rotated, two non-tapered end pulleys arranged at a predetermined angle and an outer periphery of the pulley which is stretched around the end pulleys. A conveyor belt having rotatable rollers mounted at predetermined intervals at predetermined intervals, a guide portion in which the rollers of the conveyor belt are brought into contact with a guide rail to prevent inward biasing, and a driving side and a driven side. There is provided a round conveyor belt conveying device including a roller rotation driving unit configured to bring the back surface of the transmission belt suspended on the roller into contact with the plurality of rollers to transmit the rotation of the transmission belt to each roller. Further, the present invention has a case in which the roller of the conveyor belt located on the surface is pressed and sandwiched between the transmission belt of the roller rotation drive unit and the guide rail of the guide unit, and the arc-shaped holding wall for supporting the end portion of the conveyor belt is provided. The case in which it is arranged and the bending of the conveyor belt is prevented is also included.

[0010]

In the round conveyor belt conveying device of the present invention, the back surface of the transmission belt suspended on the driving side and the driven side is brought into contact with a plurality of rollers mounted on the conveying belt, and the rotation of the transmission belt is transmitted to each roller. In addition, since the rollers are in contact with the guide portion, each roller rotated by the traveling of the transmission belt rolls and moves on the surface of the guide portion, and the conveyor belt can be smoothly and quietly conveyed. Moreover, since the two non-tapered end pulleys arranged at a predetermined angle are used, it is possible to reliably transfer a small conveyed product to another conveyor belt. Further, since the arcuate holding wall that supports the end portion of the conveyor belt is arranged, it is possible to prevent the conveyor belt from bending and maintain a good engagement relationship between the roller and the guide rail.
