工夫されていなかつた。DETAILED DESCRIPTION OF THE INVENTION When a cylindrical conveyor is curved, a tension difference occurs between the inside and outside of the cylindrical conveyor when viewed from the center of the radius of curvature, causing the belt to buckle. That is, the cylindrical shape of the pipe belt is destroyed. The present invention aims to reduce this tension difference as much as possible so that smooth bending can be achieved with a smaller bending radius. Conventionally, in order to reduce the bending radius of the bending section, high elongation canvas or the like was placed on the outside (tension side) and inside (compression side) of the belt body when viewed from the center of the radius of curvature. The rollers, etc. that hold it were not well thought out.

る。 In the case of horizontal curved conveyance or vertical curved conveyance such as a concave curve or a convex curve, the present invention changes the cross-sectional shape of the conveyor belt according to each case, thereby reducing belt deviation due to belt tension differences in the curved section. This prevents this and enables smooth music progression. Examples will be described below with reference to the drawings.

部Ｄより供給され、円筒形に保形されたコンベヤ
ベルト内を送られ排出部Ｅで排出される。 FIG. 1 is a plan view of the cylindrical conveyor, and FIG. 2 is a side view thereof. As is clear from FIG. 1, the conveyor belt is composed of a straight section A, a horizontal section B, and a vertical section C. The objects to be transported are supplied from a supply section D, sent through a conveyor belt shaped into a cylindrical shape, and discharged at a discharge section E.
第３図は直線部Ａの断面図で、これで明らかな
如く、ベルト２は８個の保形ローラ１で断面円形
に保形される。 FIG. 3 is a sectional view of the straight portion A, and as is clear from this figure, the belt 2 is kept in shape in a circular cross section by the eight shape keeping rollers 1.
次に第４図を参照するに、水平曲送部Ｂではベ

いる。 Furthermore, as shown in FIG. 5, in the vertical bending portion C, the belt 2 is kept in shape in a horizontally elliptical shape by shape keeping rollers 1 .

ことを意味している。 Now, in the horizontal bending part of Fig. 4, from the center O to the inside point a of the belt, or from the outside point b or a
The distances to the points are each reduced by α compared to conventional cylindrical conveyors. Similarly, in the C-section vertically curved portion of FIG. 5, the distance from the center O of the belt to the upper side c to the lower side d of the belt is shortened by β. In other words, this means that if the elongation rate of the belt is constant, the radius of curvature can be made smaller.
以上説明した如く、同じ仕様のベルトを使用し
ても、この発明によればより小さい曲送半径をと

と外側の張力差が本発明の場合の方が少なくな
り、ベルトのねじれ或いはずれが少なくなる。 As explained above, even if belts with the same specifications are used, according to the present invention, a smaller radius of bending can be achieved. Furthermore, if the radius is the same, the difference in tension between the inside and outside of the belt is smaller in the case of the present invention, and twisting or slipping of the belt is reduced.
なお実施例では水平曲送と垂直曲送について説
明した。しかし実際は両者の同時複合形式もある
が、この場合には、張力差がより大きい方向を偏
平にするよう保形ローラを配設するものとする。 In the embodiment, horizontal music progression and vertical music progression have been explained. However, in reality, there is also a combined type of both, but in this case, the shape-retaining rollers are arranged so as to flatten the direction in which the tension difference is greater.
なお以上の説明においては耳部のないベルトに
ついて説明したが、耳部付ベルトにおいても本発
明を適用できることは言うまでもない。 In the above description, a belt without ears has been described, but it goes without saying that the present invention can also be applied to belts with ears.
