A fixed frame 21, six straightening rollers 22 that press against the outer periphery of the outward belt 11 a rounded into a pipe shape, a support frame 23 that supports the straightening roller 22 from both ends, and a support frame 23. Further, the roller shaft 24 extending in the direction of the fixed frame 21, the rotating piece 25 attached to the other end of the roller shaft 24, and the surface of the fixed frame 21 opposite to the correction roller 22 are provided. A rotating piece rotating hand that rotates the rotating piece 25 to which the roller shaft 24 is fixed around the central axis of the roller shaft 24 to change the inclination direction of the correction roller 22. 26, torque detecting means 27 attached to the roller shaft 24, and torsion detecting means 28 for detecting the torsional state of the forward belt 11a from the torsion torque acting on each roller shaft 24 detected by the torque detecting means 27. And a control means 29 for controlling the rotating piece rotating means 26 based on the twisted state detected by the twist detecting means 28 and for controlling the direction of the correcting roller 22. The roller 22, the support frame 23, the roller shaft 24, the torque detection means 27, and the twist detection means 28 constitute a twist detection device. The rotating piece 25 and the rotating piece rotating means 26 constitute a direction changing means 30 that rotates the roller shaft 24 to change the direction of the correction roller 22.

上記矯正ローラ２２は、それぞれ、往路ベルト１１ａの走行方向に対して交差する向きに、パイプ状に丸められた部分の外周側に圧接されるが、本例では、図２（ｂ）に示すように、隣接する２つの矯正ローラ２２ａ，２２ｂを、上記往路ベルト１１ａの走行方向に対して線対称に配置するようにしている。すなわち、矯正ローラ２２ａ，２２ｂの互いに対向する端部とは反対側の端部を、それぞれ、往路ベルト１１ａの走行方向側に位置させ、上記矯正ローラ２２ａ，２２ｂがハの字形になるように、上記矯正ローラ２２ａ，２２ｂを配置する。このとき、上記往路ベルト１１ａの走行方向と上記矯正ローラ２２ａ，２２ｂの延長方向とのなす角である傾斜角は、矯正ローラ２２ａの傾斜角をθとすると、上記矯正２２ｂの傾斜角は−θとなる。
このように、隣接する２つの矯正ローラ２２ａ，２２ｂを、上記パイプ状に丸められた往路ベルト１１ａの走行方向に対して線対称に配置すると、上記パイプ状に丸められた部分に捩れが生じた場合には、例えば、図３に示すように、矯正ローラ２２ａのローラ軸２４ａは傾斜角の大きさが大きくなる方向へ捩られ、矯正ローラ２２ｂのローラ軸２４ｂは傾斜角の大きさが小さくなる方向へ捩られる。すなわち、上記ローラ軸２４ａに作用する捩れトルクの大きさと方向は、上記ローラ軸２４ｂに作用する捩れトルクの大きさと方向とは異なるので、これらの捩れトルクを、上記ローラ軸２４ａ及びローラ軸２４ｂにそれぞれ取付けられたトルク検出手段(図示せず)にて検出し、捩れ検出手段２８にて比較することにより、上記パイプ状に丸められた往路ベルト１１ａの捩じれ状態を検出することができる。 Each of the correction rollers 22 is pressed against the outer peripheral side of a portion rounded into a pipe shape in a direction crossing the traveling direction of the outward belt 11a. In this example, as shown in FIG. Further, the two adjacent correction rollers 22a and 22b are arranged symmetrically with respect to the traveling direction of the forward belt 11a. That is, the ends of the correction rollers 22a and 22b opposite to the ends opposite to each other are positioned on the traveling direction side of the outward belt 11a, respectively, so that the correction rollers 22a and 22b are in a C shape. The correction rollers 22a and 22b are disposed. At this time, the inclination angle formed by the traveling direction of the forward belt 11a and the extending direction of the correction rollers 22a and 22b is assumed to be θ, and the inclination angle of the correction 22b is −θ. It becomes.
As described above, when the two adjacent straightening rollers 22a and 22b are arranged in line symmetry with respect to the traveling direction of the outward belt 11a rounded into the pipe shape, the twisted portion occurs in the portion rounded into the pipe shape. In this case, for example, as shown in FIG. 3, the roller shaft 24a of the correction roller 22a is twisted in a direction in which the inclination angle increases, and the roller shaft 24b of the correction roller 22b decreases in inclination angle. Twisted in the direction. That is, the magnitude and direction of the torsional torque acting on the roller shaft 24a is different from the magnitude and direction of the torsional torque acting on the roller shaft 24b, so that these torsional torques are applied to the roller shaft 24a and the roller shaft 24b. By detecting with a torque detecting means (not shown) attached thereto and comparing with the torsion detecting means 28, it is possible to detect the twisted state of the forward belt 11a rounded into the pipe shape.

次に、上記向き変更手段３０について説明する。
固定フレーム２１の上記ローラ軸２４に対向する箇所には、図４（ａ）に示すように、貫通孔２１ｈが設けられており、この貫通孔２１ｈには上記ローラ軸２４に固定され、上記貫通孔２１ｈに回転自在に嵌合するナット２４ｎが挿入されている。また、回動片２５には、上記ローラ軸２４の他端側を固定する固定ボルト２５ａを挿入するためのボルト挿入孔２５ｂが設けられている。そして、上記回動片２５の矯正ローラ２２とは反対側の面から、固定ボルト２５ａをローラ軸２４の他端側に予め形成しておいたネジ穴２４ｋに螺入することにより、上記矯正ローラ２２を上記回動片２５に固定することができる。したがって、上記回動片２５を上記ローラ軸２４の中心軸を中心軸として上記回動片２５を回転させれば、上記矯正ローラ２２の傾斜角を変更することができる。
また、本例では上記回動片回転手段２６を、図４（ｂ）に示すように、上記回動板２５に立設された連結突片２６ａ，２６ａと、この連結突片２６ａ，２６ａ間に配置され、上記連結突片２６ａ，２６ａに当接するナット２６ｂと、上記ナットを貫通する送りネジ２６ｃと、上記固定フレーム２１に固定され、上記送りネジ２６ｃの両端側を回転自在に支持する突片２６ｄ，２６ｄと、上記送りネジ２６ｃの一端部に取付けられたスプロケット２６ｅとから構成している。これにより、上記スプロケット２６ｅにチェーン２６ｆを掛け渡して、上記チェーン２６ｆにより上記スプロケット２６ｅを回転させれば、上記ナット２６ｂが送りネジ２６ｃに沿って移動するので、上記連結突片２６ａ，２６ａに連結された上記回動片２５を回転させことができる。
したがって、捩れ検出手段２８で検出した上記パイプ状に丸められた往路ベルト１１ａの捩じれ状態のデータを制御手段２９に送って、上記捩れを矯正するため矯正ローラ２２の向きを演算した後、上記回動片回転手段２６を制御して回動片２５を回転させ、矯正ローラ２２の向きを変更するようにすれば、上記往路ベルト１１ａの捩れを確実に矯正することができる。 Next, the direction changing means 30 will be described.
As shown in FIG. 4 (a), a through hole 21h is provided at a portion of the fixed frame 21 that faces the roller shaft 24. The through hole 21h is fixed to the roller shaft 24 and passes through the through hole 21h. A nut 24n that is rotatably fitted in the hole 21h is inserted. The rotating piece 25 is provided with a bolt insertion hole 25b for inserting a fixing bolt 25a for fixing the other end of the roller shaft 24. The fixing roller 25a is screwed into a screw hole 24k formed in advance on the other end side of the roller shaft 24 from the surface opposite to the correcting roller 22 of the rotating piece 25, thereby correcting the correcting roller. 22 can be fixed to the rotating piece 25. Therefore, if the rotating piece 25 is rotated about the central axis of the roller shaft 24, the inclination angle of the correction roller 22 can be changed.
Further, in this example, as shown in FIG. 4 (b), the rotating piece rotating means 26 is connected to the connecting protrusions 26a and 26a erected on the rotating plate 25 and the connecting protrusions 26a and 26a. A nut 26b that is in contact with the connecting protrusions 26a, 26a, a feed screw 26c that penetrates the nut, and a protrusion that is fixed to the fixed frame 21 and rotatably supports both ends of the feed screw 26c. It consists of pieces 26d, 26d and a sprocket 26e attached to one end of the feed screw 26c. As a result, when the chain 26f is looped over the sprocket 26e and the sprocket 26e is rotated by the chain 26f, the nut 26b moves along the feed screw 26c, so that it is connected to the connecting protrusions 26a and 26a. The rotated piece 25 can be rotated.
Therefore, the data of the twisted state of the outward belt 11a rounded into the pipe shape detected by the twist detection means 28 is sent to the control means 29, the direction of the correction roller 22 is calculated to correct the twist, and then the rotation is performed. If the moving piece rotating means 26 is controlled to rotate the rotating piece 25 and the direction of the correction roller 22 is changed, the twist of the forward belt 11a can be reliably corrected.

このように、本最良の形態によれば、往路ベルト１１ａの丸められた部分の外周側に圧接する矯正ローラ２２を複数個とし、かつ、隣接する２つの矯正ローラ２２ａ，２２ｂとを上記搬送ベルト１１の走行方向に対して線対称に配置するとともに、上記矯正ローラ２２の支持フレーム２３に取付けられたローラ軸２４に、このローラ軸２４の捩れトルクを検出するトルク検出手段２７を設けて、ローラ軸２４に作用する捩れトルクから上記往路ベルト１１ａの捩れ状態を検出するようにしたので、簡単な構成で、パイプコンベヤ１０の捩れ状態を精度よく検出することができる。
また、上記矯正ローラ２２の向きを変更する手段として、上記ローラ軸２４の他端側に取付けられる回動片２５と、固定フレーム２１に設けられ、上記回動片２５を回転させる回動片回転手段２６とから成る向き変更手段３０を設けるとともに、上記検出された往路ベルト１１ａの捩れ状態に基づいて上記向き変更手段３０を制御し、上記矯正ローラ２２の向きを変更して、上記往路ベルト１１ａの捩れを矯正するようにしたので、パイプコンベヤ１０の捩れ状態を容易にかつ確実に矯正することができる。 As described above, according to the best mode, a plurality of the correction rollers 22 that are pressed against the outer peripheral side of the rounded portion of the outward belt 11a are provided, and the two adjacent correction rollers 22a and 22b are connected to the conveyor belt. 11 is arranged in line symmetry with respect to the traveling direction of 11 and a torque detecting means 27 for detecting the torsional torque of the roller shaft 24 is provided on the roller shaft 24 attached to the support frame 23 of the correction roller 22. Since the torsional state of the forward belt 11a is detected from the torsional torque acting on the shaft 24, the torsional state of the pipe conveyor 10 can be accurately detected with a simple configuration.
Further, as means for changing the direction of the correction roller 22, a rotating piece 25 attached to the other end of the roller shaft 24 and a rotating piece rotation provided on the fixed frame 21 to rotate the rotating piece 25. A direction changing means 30 comprising means 26 is provided, and the direction changing means 30 is controlled on the basis of the detected twisted state of the forward belt 11a to change the direction of the correction roller 22 to thereby change the forward belt 11a. Thus, the twisted state of the pipe conveyor 10 can be easily and reliably corrected.

なお、上記最良の形態では、矯正ローラ２２の数を６個としたが、これに限るものではなく、搬送物の最大重量やパイプコンベヤの長さ等により適宜決定すればよい。但し、その場合でも、矯正ローラ２２の数は偶数個とするとともに、隣接する２つのローラを搬送ベルトの走行方向に対して線対称に配置する必要があることはいうまでもない。
また、上記例では、送りネジ機構を備えた回動片回転手段２６により上記回動片２５を回転させるようにしたが、回動片回転手段はこれに限定されるものではなく、上記回動板を数度以下の範囲で回転させることのできる構成であれば、上記回動片２５にハンドルを立設し、このハンドルを固定フレーム２１に設けた回転手段により回転させるなど、他の周知の板状部材の回転機構を用いてもよい。 In the above-described best mode, the number of correction rollers 22 is 6. However, the number of correction rollers 22 is not limited to this, and may be determined as appropriate depending on the maximum weight of the conveyed product, the length of the pipe conveyor, and the like. However, even in this case, it is needless to say that the number of correction rollers 22 is an even number and two adjacent rollers need to be arranged symmetrically with respect to the traveling direction of the conveyor belt.
In the above example, the rotating piece 25 is rotated by the rotating piece rotating means 26 provided with the feed screw mechanism. However, the rotating piece rotating means is not limited to this, and the rotating piece rotating means 26 is not limited thereto. As long as the plate can be rotated within a range of several degrees or less, a handle is erected on the rotating piece 25, and the handle is rotated by a rotating means provided on the fixed frame 21. You may use the rotation mechanism of a plate-shaped member.

このように、本発明によれば、パイプコンベヤの捩れ状態を容易にかつ精度よく検出することができるとともに、この捩じれを正確に矯正することができるので、パイプコンベヤを安定して作動させることができ、搬送物を確実に搬送することができる。   As described above, according to the present invention, the twisted state of the pipe conveyor can be detected easily and accurately, and the twist can be accurately corrected, so that the pipe conveyor can be stably operated. It is possible to reliably convey the conveyed product.
