本発明は、平ベルトを上向きにパイプ状に丸め
て、搬送物が飛散しないようにして搬送し得るよ
うにしたパイプコンベアに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a pipe conveyor in which a flat belt is rolled upward into a pipe shape so that objects can be transported without scattering.
概略を第３図及び第４図に示すように、前後端
部所定の位置に配設されたローラ３１，３２の間
に無端帯状のゴム製の搬送ベルト３３を掛け回
し、その少なくとも上側の往路部分を、多数の保

例えば、後部ローラ３２の近くに設けたホツパー
３５より投入した被搬送物３６を包め込んで搬送
するようにしたパイプコンベアは公知である。
As schematically shown in FIGS. 3 and 4, an endless belt-shaped rubber conveyor belt 33 is wound between rollers 31 and 32 disposed at predetermined positions at the front and rear ends, and at least the upper outward path The portion is rolled upward by a number of shape-retaining rollers 34, and inside it,
For example, a pipe conveyor is known in which a conveyed object 36 introduced from a hopper 35 provided near a rear roller 32 is encased and conveyed.
このようなパイプコンベアにおいて、ローラ３
１，３２間の距離が長いと、搬送ベルト３３の各

In such a pipe conveyor, roller 3
If the distance between 1 and 32 is long, slight differences in the dimensions and properties of each part of the conveyor belt 33, uneven wear of the shape retaining roller 34, and accumulation of precision errors in each part may cause the conveyor belt 33 to may become twisted.
そのため、搬送ベルトの走行は不円滑となり、
しかも、パイプコンベア自体は、通常、この捩れ
に対する復元性を備えていないので、捩れは次第

閉塞部が、側方から、さらに下方を向くに至り、
被搬送物が落下するとともに、搬送ベルトや保形
ローラ等に無理な負荷を与え、その損耗を早める
こととなる。 As a result, the conveyor belt runs unsmoothly,
Moreover, the pipe conveyor itself usually does not have the ability to recover from this twisting, so the twisting gradually increases, and the blocked part of the outgoing path, which was originally facing upwards, ends up facing sideways and even downwards.
As the conveyed object falls, an unreasonable load is applied to the conveyor belt, shape retaining rollers, etc., and their wear and tear is accelerated.
このような問題点を解決するためには、捩れを
早期に発見して、例えば本出願人等による特開昭

れているように、検知ローラでこの捩れを検出
し、それに基づいて、電気的もしくは油圧式手段
で矯正することが考えられている。 In order to solve these problems, it is necessary to discover the twist at an early stage, and for example,
Can it be corrected manually as described in Japanese Patent No. 57-141304? Or JP-A-57-145709
As described in Japanese Patent Laid-Open No. 57-151508, it has been proposed to detect this twist with a detection roller and correct it using electric or hydraulic means based on the detected twist.
搬送ベルトの捩れを直接的に監視することは、
実際的ではなく、また、搬送ベルトの表面に検知

検出は困難であるとともに、かなりの時間的遅れ
は避け難く、捩れ発生の初期において、的確な矯
正措置を構ずることはできないのが実情である。 Directly monitoring the torsion of the conveyor belt is
It is not practical, and even if the detection roller is brought into direct contact with the surface of the conveyor belt and the torsion is determined by the inclination of the detection roller, it is difficult to detect even the slightest torsion, and it is difficult to detect the slightest torsion. Time delays are unavoidable, and the reality is that it is not possible to take appropriate corrective measures in the early stages of twisting.
また、検知ローラが搬送ベルトに常時接触して
いるため、その耐久性にも問題があつた。 Furthermore, since the detection roller is in constant contact with the conveyor belt, there is also a problem in its durability.

ある。 If the conveyor belt is a flat belt or a U-shaped belt, for example, Japanese Utility Model Application No. 59-108727,
As disclosed in Japanese Utility Model Application Publication No. 59-170508, meandering of the conveyor belt can be detected by detecting the positions of both side edges of the conveyor belt using photoelectric sensors. If the conveyor belt is completely rounded, with both edges overlapping each other, such as on a pipe conveyor,
There is a drawback in that the positions of both side edges of the conveyor belt cannot be easily detected using a photoelectric sensor or the like.
本発明は、両側縁部が互いに重合するようにし

のに役立たせようとするものである。 According to the present invention, even if a conveyor belt, which is rolled up so that both side edges overlap each other, is twisted even slightly, this can be immediately detected by a simple means, and the twist can be properly adjusted. It is intended to help in taking corrective measures.
