) and both ends (1b) are stretched evenly by the traction force of the front roller (2).
The end face (2a) of the front roller (2) that starts contact with the
It was positioned on an extension of the central axis (L) of the pipe-shaped portion of the conveyor belt (1).
なお、後部ローラ（３）と搬送ベルト（１）の関係は、
前部ローラ（２）の場合と同様につき、図示を省略する
。The relationship between the rear roller (3) and the conveyor belt (1) is as follows:
It is the same as the case of the front roller (2), and illustration thereof is omitted.
上述のパイプコンベヤにおいて、展開部近くにおいて丸
められた搬送ベルト（１）の両側端部（ｔｂ）は、互い
に連続しておらず、単に重合しているだけであるので１
両側端部（ｌｂ）の応力は互いに無関係に発生し、応力
分布は非連続となる。In the pipe conveyor described above, the both ends (tb) of the conveyor belt (1) that are rolled up near the unfolded part are not continuous with each other and are simply overlapped.
Stresses at both end portions (lb) are generated independently of each other, and the stress distribution is discontinuous.
したがって、搬送ベルト（１）のわずかの捩れ等によっ
ても１両側端部（１ｂ）の応力に差が生じ、各部の伸長
量が異なったり、樋状の展開部が傾斜したり、平板状の
展開部がローラ（２）に接する点で側方に片寄ったりす
るおそれがある。Therefore, even a slight twist of the conveyor belt (1) causes a difference in the stress at both ends (1b) of the conveyor belt (1), resulting in differences in the amount of elongation of each part, an inclination of the trough-like unfolding part, or a flat plate-like unfolding. There is a risk that the portion may be biased to the side at the point where it contacts the roller (2).
本発明は、展開した搬送ベルトと接触を開始する上記ロ
ーラの端面を、搬送ベルトにおけるパイプ状に丸められ

、中央部（ｌａ）がけん引力を最も強く受けるが。In the present invention, the conveyor belt (1
) and the end face (2a) of the front roller (2), the center part (la) is longer than both ends (lb), so the center part (la) receives the strongest traction force. .
中央部（ｌａ）は抗張力が大きいので伸び難い。The central portion (la) has a large tensile strength and is difficult to stretch.
従って、屈曲部全体としての伸びが減少し、しかも上記
直線距離の短い側端部（１ｂ）は、伸びが少ないので、
両側端部（１ｂ）の長さに差が生じにくく、平板状に展
開した搬送ベルト（１）が、前部ローラ（２）において
片寄りにくくなる。Therefore, the elongation of the bent portion as a whole decreases, and the side end portion (1b) with the short straight line distance has less elongation.
Differences in length between both end portions (1b) are less likely to occur, and the flat conveyor belt (1) is less likely to shift to one side on the front roller (2).

中央部（ｌａ）より短くなるようにしである。As shown in the figure, the present invention provides a front roller (2) with an end face (
2a) above the central axis (L) of the pipe-shaped rounded portion of the conveyor belt (1), preferably an extension of the overlapping portion of both ends (1b) of the pipe-shaped conveyor belt (1). By positioning it on the line, the straight distance between each part of the conveyor belt (1) and the end surface (2a) at the development start point (shape retaining frame (6) in Figure 1) can be It is designed to be shorter than the central part (la).

発明を効果的に適用することができる。Furthermore, the above is a case of a pipe conveyor in which the outer surface of the negative end and the inner surface of the other end of the conveyor belt (1) are overlapped and rolled into a pipe shape, but as shown in FIG.
), the inner surfaces of both sides of the pipe are overlapped and rolled into a pipe shape, or the inner surfaces of both sides of
The present invention can also be effectively applied to pipe conveyors that are simply brought into contact or in close proximity.

ることができる。By having the above-mentioned configuration, the present invention has the above-mentioned [effect], in which the linear distance between each part of the conveyor belt and the end surface of the roller at the starting point of the conveyor belt is adjusted to The two sides are made shorter than the center part, so that the traction force by the rollers is received most strongly at the center part, where the tensile strength is large, and the elongation at both ends is made small, thereby reducing the stress generated at both ends to the stress generated at the center part. Accordingly, the absolute amount of stress difference generated at both end portions can be made significantly smaller than the absolute amount of stress generated at the center portion.
これによって、搬送ベルトの両側端部の伸びの差をでき
