That is, when the ears are in use, the outer surfaces of the ears are strongly pressed by a rotating roller or the like, so that the ears are shaped like palms together.
又耳部の各端面は端部ローラにより、押圧される。Further, each end surface of the ear portion is pressed by an end roller.

円筒形を形成するコンベア部の横方向の長さを１００と
した場合に、各耳部の巾は２〜１０程度が適当である。The width of the ears is determined by the overall size of the conveyor belt, the object to be conveyed, etc. In general,
When the lateral length of the cylindrical conveyor section is 100 mm, the appropriate width of each ear section is about 2 to 10 mm.
耳部の内表面は内表面どうしが接験し、かつ外表面には
強圧ローラが接触する。このために耳部の内表面、外表
面は他のコンベアベルトの部分より耐摩耗性の高い材料
で構成するのが好ましい。The inner surfaces of the ears are in contact with each other, and the outer surfaces are in contact with a high pressure roller. For this reason, it is preferable that the inner and outer surfaces of the ears be made of a material that has higher abrasion resistance than other parts of the conveyor belt.
又、耳部は横断方向に高い剛性を有するものが好ましい

ことができる。The neck is located inside each ear. This neck corresponds to the opening of the conveyor section which is bent into a cylindrical shape. This neck is subjected to the greatest bending in the transverse direction. Also, the bending direction is different from other conveyor parts, and the inner surface is convex. Neck width□
The optimum value can also be determined depending on the purpose of the conveyor belt.
一般的には、円筒形を形成するコンベア部の横断方向の

ついては後でコンベア部全体として説明する。Generally, when the length in the transverse direction of the cylindrical conveyor section is 100, the width of each neck section in the transverse direction is preferably about 0.5 to 10. Note that the rigidity of the neck will be explained later regarding the entire conveyor section.

各傾斜部の巾もコンベア部の横方向の長さを１００とし
た場合に１０〜１５程度が適当である。The inclined part constitutes an arc-shaped part diagonally upward when bent into a cylindrical shape, and exists between the neck part and the side part. The appropriate width of each inclined portion is about 10 to 15, assuming that the lateral length of the conveyor portion is 100.

In this case, about 20 to 30 is appropriate.
本発明においては、上記説明した首部の横断方向の剛性
が耳部、他のコンベア部を含めたどの部分の剛性よりも
小さい。即ち、柔らかくできている。In the present invention, the stiffness of the neck in the transverse direction described above is smaller than the stiffness of any part including the ears and other conveyor parts. In other words, it is made of soft material.

は、剛性が小さい、即ち、柔かいと大きな値となる。As one indicator of the rigidity of a conveyor belt, there is a trough performance test method based on the standards of the Japan Rubber Association. Here, trough performance was measured using the following method according to this standard. That is, the belt width in the vertical direction is 150 mm and the belt width in the horizontal direction (this is Lmm) is 900 mm, and a rectangular test piece is suspended in four sections using a hanging device, and the average value (Fmm) of the deflection at the center of the test piece is calculated. It was measured. The trough performance T of this test piece is expressed as T-F/L. Trough performance T
has a large value when the stiffness is small, that is, it is soft.

中央に当る底部のトラフ性能を基準として、各部分の剛
性（トラフ性能）を説明する。The transverse stiffness of the conveyor belt of the present invention is expressed by this trough performance T. The rigidity (trough performance) of each part will be explained based on the trough performance of the bottom, which is the centermost part of the cylindrical conveyor belt.

ようにするのがよい。When the trough performance at the bottom in the transverse direction is 100, the trough performance at the neck is preferably 15.0 to 400. Note that the thickness of the neck portion may be thinner than the thickness of other conveyor belts to improve trough performance. In this case,
Preferably, at least one side of the neck is provided with a groove extending in the longitudinal direction.

本発明の円筒形コンベアベルトにおいて、真円に近いコ
ンベア部を達成するために、最も大きく質献する部分が
首部である。これはコンベアベルト横方向の厚さを一定
範囲におさえ、断面形状を平板状としたために、必然的
に首部に大きな曲げ歪が作用する。首部を柔らかくした
のはこの曲げ変形を容易にするためである。In the cylindrical conveyor belt of the present invention, in order to achieve a conveyor section that is close to a perfect circle, the neck section is the part that is pledged the most. This is because the thickness of the conveyor belt in the lateral direction is kept within a certain range and the cross-sectional shape is flat, so that a large bending strain inevitably acts on the neck. The purpose of making the neck soft is to facilitate this bending deformation.
なお、首部のみの剛性を小さくし、他の部分を首部の剛
性より高いほぼ同一の剛性を有するものとすることもで
きる。このような首部のみを柔らかくした断面平板状の
コンベアベルトは、円筒形に変形したときの真円度は比
較的低いが、直線走行用円筒形コンベアベルトのように
屈曲の少ないコンベアベルトには使用できる。Note that it is also possible to reduce the stiffness of only the neck and make the other parts have substantially the same stiffness that is higher than the stiffness of the neck. A conveyor belt like this, which has a flat cross-section with only the neck softened, has relatively low roundness when deformed into a cylindrical shape, but it can be used for conveyor belts with little bending, such as cylindrical conveyor belts that run in a straight line. can.
更に真円度の高い円筒形コンベアベルトとするためには
側部の剛性を首部の剛性の次に小さくする必要がある。Furthermore, in order to obtain a cylindrical conveyor belt with a high degree of roundness, it is necessary to make the rigidity of the side portions the second smallest after that of the neck portion.
さらに、円筒形を真円に近づける場合には傾斜部の剛性
を底部の剛性より高くするようにする。これは従来のコ

部が立ちあがる傾向にある。傾斜部および底部を側部よ
り硬くすることにより傾斜部および側部を水平方向に伸
びるように維持させ、側部で曲るようにするものである
。Furthermore, when the cylindrical shape is made to be close to a perfect circle, the rigidity of the inclined part is made higher than that of the bottom part. This is because, as shown in FIG. 10, when a conventional conveyor belt runs around a corner, the sides tend to rise. By making the sloped part and the bottom part harder than the side parts, the sloped part and the sides can be maintained in a horizontally extending manner, and can be bent at the sides.
円筒形コンベアベルトの横断方向における剛性を変化す
るには、横断方向に埋設される補強層の数を増減させた
り、あるいは剛性の大きい補強層、剛性の小さい補強層
を組み合わせて使用する等により、横断方向の剛性を変
化することができる。To change the stiffness of a cylindrical conveyor belt in the transverse direction, increase or decrease the number of reinforcing layers buried in the transverse direction, or use a combination of reinforcing layers with high stiffness and reinforcing layers with low stiffness, etc. The transverse stiffness can be varied.
尚、横断方向における円筒形コンベアベルトの全体の一
体性を保つために、少なくとも中央部に配置される補強
層は、横断方向において、首部を少なくとも１層の補強
層が連通しているのが好ましい。In order to maintain the overall integrity of the cylindrical conveyor belt in the transverse direction, it is preferable that the reinforcing layer disposed at least in the center has at least one reinforcing layer communicating with the neck in the transverse direction. .
円筒形コンベアベルト全体の長手方向の剛性については
、可能な限り均質にするのが好ましい。The longitudinal stiffness of the entire cylindrical conveyor belt is preferably as homogeneous as possible.

性と同一にすることもできる。Further, it is more preferable that the ears, neck, slope, sides, and bottom have the same stiffness in the longitudinal direction, but the stiffness in the longitudinal direction of each of these parts may be different. For example, the stiffness of each of these parts in the longitudinal direction may be the same as the stiffness of each part in the transverse direction.

It is preferable to have a pair of clamping rollers for clamping from the outer surface and a roller at the end defining the end surface of the ear. Furthermore, it is more preferable to use a structure in which one additional guide roller is provided at the bottom and one at the side. is in the form of a sheet with a nearly constant wall thickness. This width i
Since there is no thick part in the wall thickness in the direction, the mold used for manufacturing such as vulcanization becomes simple, and the cylindrical conveyor belt is extremely easy to pack and transport. Furthermore, when used as a cylindrical conveyor belt, no abnormal strain is applied to the ears and neck, making it durable. Furthermore, since the transverse direction stiffness of the cylindrical conveyor belt is set to a certain degree depending on each part, the cylindrical shape formed by the cylindrical conveyor belt is close to a perfect circle, and the conveyance of objects on the cylindrical conveyor belt is improved. becomes easier. Furthermore, even when the cylindrical conveyor belt bends and travels, the cross section remains relatively circular.
