本考案は、挟圧ローラ等によつて円筒形を形成

ルトの曲率半径が小さくなり、ベルトの断面積が
小さくなるという問題が生じている。 As conventional cylindrical conveyor belts, a cylindrical conveyor belt 100 having enlarged portions 101 on both side edges, whose cross section is shown in FIG. 1, and a conveyor belt 200, whose cross section is shown in FIG. 3, are known. The conveyor belt 100 having enlarged portions 101 on both side edges is used as shown in FIG.
A plurality of rollers 300 form a cylindrical shape.The outer surface of the conveyor belt 100 is compressed by the plurality of rollers 300 to form a cylindrical shape, and both side edges are pressed to the neck portion of the enlarged portion 101 via press rollers 301. They abut and hold the conveyor belt in a cylindrical shape. This conveyor belt 100 requires enlarged portions 101 on both sides, making it expensive and requiring special manufacturing equipment. In addition, stepped pulleys are required for the pulleys supporting the conveyor belt, which further increases costs. Moreover, when this conveyor belt is run in a curve, its cross section is shown in Figure 2, and the inner part of the curve (the right part in Figure 2) rises up, causing two parts that are in close contact with each other. The ampulla 101 is displaced in the vertical direction. In order to prevent the enlarged portion 101 from shifting, it also has the disadvantage of requiring a presser roller (not shown). In other conventionally known cylindrical conveyor belts 200, since the shape of the conveyor belt 200 itself is simple, the conveyor belt itself is complicated, such as the cylindrical conveyor belt 100 shown in FIGS. 1 and 2 described above. There are no problems caused by the shape. However, when this conveyor belt 200 is also run in a curve, the outside of the bent portion (the upper left part of FIG. 4) rises and the cylindrical shape is formed, as shown in the cross section of FIG. 4. The diameter becomes smaller. Therefore, a problem arises in that the radius of curvature of the belt becomes smaller and the cross-sectional area of the belt becomes smaller.
本考案は、上記した円筒形コンベアベルトの曲
線走行時に生ずる問題点のない円筒形コンベアベ
ルトを提供することを目的とするものである。 The object of the present invention is to provide a cylindrical conveyor belt that does not have the above-mentioned problems that occur when the cylindrical conveyor belt runs on curves.

接することを特徴とするものである。 In other words, the cylindrical conveyor belt of the present invention is a cylindrical conveyor belt in which one side edge is overlapped with the other side edge using a pressure roller or the like to form a cylindrical shape. An engaging portion consisting of a flat sliding portion and a locking portion having a locking surface substantially orthogonal to the sliding portion is provided on at least one of the surface or the inner surface of the other overlapping side edge, and It is characterized in that the side ends of the side edges come into contact with the locking surface of the locking portion.

もつものとすることができる。 The cylindrical conveyor belt of the present invention is characterized in that at least one side edge is provided with an engaging portion consisting of a flat sliding portion and one locking portion having a locking surface substantially perpendicular to the sliding portion. has. The engaging portion includes a flat sliding portion and one locking portion having a locking surface substantially orthogonal to the sliding portion. Therefore, the central portion, excluding the side edges, can have the same shape and structure as a conventional conveyor belt.

い。 Note that the engaging portion may be formed only on at least one of the outer surface of one of the overlapping side edges or the inner surface of the other overlapping side edge. Alternatively, an engaging portion may be formed on both side edges, and the side ends of each side edge may abut against the locking portion of the engaging portion on the other side edge. In this case, one side edge may be an engaging portion with a chipped outer surface side, and an engaging portion with a chipped inner surface side symmetrically with the one side edge. Further, a protruding stopper part is formed as a locking part on at least one of the outer surface and inner surface of the sheet-like conveyor belt at a position spaced apart from the side edge thereof by a certain distance, and the protruding stopper part and the side edge The surface between the two may be used as a sliding part.

なり、断面積の減少による不都合、両側縁が離れ
ることによる不都合がなくなる。 When the cylindrical conveyor belt of the present invention is pressed by a pressure roller to form a cylindrical shape, a The slide part slides and gradually forms a cylindrical shape. Therefore, the sliding resistance between the outer surface or the inner surface and the sliding portion is small, and it is easy to form a cylindrical shape. and,
The side end of one side edge abuts the locking surface of the locking portion of the other side edge, and a very small cylindrical shape is defined. For this reason, the side end of the other side edge that abuts the locking surface of the locking portion cannot wrap around beyond the locking portion, so that a smaller cylindrical shape is not formed. For this reason, even when the cylindrical conveyor belt travels around a curve and is bent, its cross-sectional area does not decrease. Also. Even when the edges of both sides overlap each other, the gap between the pressure rollers is shifted and a slightly larger cylindrical shape is formed.
The both side edges are kept overlapping each other, and the seal on both side edges is maintained. Therefore, the cylindrical shape of the cylindrical conveyor belt can be maintained reliably, and problems caused by a reduction in cross-sectional area and problems caused by separation of both side edges are eliminated.

The thickness of the conveyor belt 1 is about half that of the center of the conveyor belt. The conveyor belt 1 is reinforced with a plurality of canvases 13 and steel cords 14 arranged in parallel to the length of the conveyor belt 1.
In the stepped portions 11 and 12, a smaller number of sheets of canvas 13 are embedded than in the central portion. Also, no steel cords 14 are embedded in the stepped portions 11 and 12.

造となつている。 The cylindrical conveyor belt 1 of this embodiment has stepped portions 11 and 12 formed on both side edges.
In this case, both ends of both edges abut each other on the step portions 11a and 11b, and the formed cylindrical shape becomes smaller because the formed cylindrical shape is stopped by the step portions 11a and 11b in the direction in which the formed cylindrical shape becomes smaller. It won't happen.
Further, since both stepped portions 11 and 12 overlap each other, there is no fear that the peripheral edge portions will shift and the seal will be broken. In addition, in the stepped parts 11 and 12, the number of reinforcing canvas 13 buried is smaller than in the central part, and the steel cord 14 is not buried, so the stepped parts 11 and 12 are more flexible than in the central part. It has a flexible structure.

シールも確実である。Example 2 A cross section of a cylindrical conveyor belt according to a second example is shown in FIG. This conveyor belt 2 has a protruding stopper part 21 formed on one surface of one peripheral edge at a constant interval from the end thereof, and a step part 21a on the side edge thereof. In addition, the stopper part 21
The conveyor belt body is almost the same as the conventional conveyor belt, except for the conveyor belt. In this embodiment, the number of sheets of canvas as reinforcing materials buried in both peripheral edges of the conveyor belt 2 is small, and no steel cords are buried in both peripheral edges. This makes both peripheral edges of the conveyor belt 2 flexible relative to the center. As shown in FIG. 8 in use, this cylindrical conveyor belt 2 has its other peripheral side end abutting against the stepped portion 21a of the stopper portion 21, thereby regulating the minimum diameter of the cylindrical shape formed. Therefore, the cross section will not be reduced below its minimum circularity. Furthermore, since both peripheral edges overlap each other, the sealing is reliable.
