Abstract

PROBLEM TO BE SOLVED: To provide a belt conveyor capable of saving power in operation power, and without receiving influence of a ferromagnetic substance on a conveyor belt.SOLUTION: In a belt conveyor where a roller 2 is arranged under an endless conveyor belt 1 wound around a pair of pulleys, a diamagnetic substance 5 is adhered to a reverse surface of the conveyor belt 1 opposed to the roller 2, and a magnet 6 is arranged in the roller 2.

Description

本発明はベルトコンベヤに関し、更に詳しくは、運転動力を省力化することができると共に、コンベヤベルトが強磁性体の影響を受けることがないようにしたベルトコンベヤに関する。   The present invention relates to a belt conveyor, and more particularly, to a belt conveyor that can save operating power and that the conveyor belt is not affected by a ferromagnetic material.

一般的に、運搬物を搬送するベルトコンベヤのコンベヤベルトは、長手方向に所定の間隔を置いて回転自在に設置された複数のローラーに接触しながら走行している。そのため、コンベヤベルトとローラーとの間に摩擦抵抗が発生し、ベルトコンベヤの運転動力を増大させる原因となっている。   In general, a conveyor belt of a conveyor belt that conveys a transported object travels in contact with a plurality of rollers that are rotatably installed at predetermined intervals in the longitudinal direction. For this reason, frictional resistance is generated between the conveyor belt and the roller, which increases the driving power of the belt conveyor.

また、空気浮上式ベルトコンベヤのように、フレーム内で空気圧によりコンベヤベルトを浮上させるタイプのベルトコンベヤでは、上記のような接触による摩擦抵抗が発生することは少ないが、圧縮空気を送り出すコンプレッサーの駆動に多大な運転動力が必要となる。また、コンベヤベルトが幅広になると、ベルト幅方向の端部がフレーム内面と接触する可能性が高くなるため、より多くの圧縮空気を送り込まなければならない。   Also, in the type of belt conveyor that lifts the conveyor belt by air pressure in the frame, such as an air-floating belt conveyor, the frictional resistance due to the contact as described above is low, but the drive of the compressor that sends out the compressed air In addition, a large amount of driving power is required. Further, when the conveyor belt becomes wider, the possibility that the end portion in the belt width direction comes into contact with the inner surface of the frame increases, so that more compressed air must be fed.

このような問題を解決するため、特許文献１は、コンベヤベルトの裏面にマグネットベルトを装着すると共に、そのマグネットベルトと同じ磁極を有するマグネットプレートをコンベヤベルトの下方に設置することで、コンベヤベルトを磁力により反発支持するようにしたベルトコンベヤを提案している。   In order to solve such a problem, Patent Document 1 attaches a magnet belt to the back surface of the conveyor belt and installs a magnet plate having the same magnetic pole as the magnet belt below the conveyor belt. We have proposed a belt conveyor that is supported by a magnetic force.

しかしながら、上記のベルトコンベヤでは、コンベヤベルト自体が磁力を有するようになるため、ベルトコンベヤの近傍に鉄などの強磁性体が存在すると、引力が発生してベルトの蛇行や偏走行が発生するおそれがある。また、鉄製治具を用いてのコンベヤベルトの取付作業やメンテナンスに支障をきたす可能性もある。   However, in the above belt conveyor, since the conveyor belt itself has a magnetic force, if a ferromagnetic material such as iron exists in the vicinity of the belt conveyor, an attraction may be generated, and the belt may meander or unevenly travel. There is. In addition, there is a possibility that the installation work and maintenance of the conveyor belt using an iron jig may be hindered.

本発明の目的は、運転動力を省力化することができると共に、コンベヤベルトが強磁性体の影響を受けることがないようにしたベルトコンベヤを提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a belt conveyor that can save operation power and that the conveyor belt is not affected by a ferromagnetic material.

上記の目的を達成する本発明のコンベヤベルトは、一対のプーリーに掛け回された無端状のコンベヤベルトを備えたベルトコンベヤにおいて、前記コンベヤベルトの裏面に反磁性体を装着すると共に、前記反磁性体に対向する位置に回転自在なローラーを備え、該ローラーの内部に磁石を設置したことを特徴とするものである。   The conveyor belt of the present invention that achieves the above object is a belt conveyor provided with an endless conveyor belt wound around a pair of pulleys, and a diamagnetic material is mounted on the back surface of the conveyor belt, and the diamagnetic A rotatable roller is provided at a position facing the body, and a magnet is installed inside the roller.

本発明のベルトコンベヤによれば、コンベヤベルトの裏面に反磁性体を装着すると共に、その反磁性体に対向する位置に磁石を設置したので、反磁性体と磁石の反発力によりコンベヤベルトが浮上して、ローラーなどの他の部品との接触が抑えられるため、運転動力を省力化することができる。また、反磁性体は強い外部磁場に対してのみ反磁性を示すため、コンベヤベルトは鉄などの強磁性体の影響を受けることはないので、ベルト走行を安定させることができる。   According to the belt conveyor of the present invention, a diamagnetic material is mounted on the back surface of the conveyor belt, and a magnet is installed at a position facing the diamagnetic material, so that the conveyor belt is lifted by the repulsive force of the diamagnetic material and the magnet. And since contact with other components, such as a roller, is suppressed, driving power can be saved. Further, since the diamagnetic material exhibits diamagnetism only with respect to a strong external magnetic field, the conveyor belt is not affected by a ferromagnetic material such as iron, so that the belt running can be stabilized.

本発明の実施形態からなるベルトコンベヤの往路側の断面図である。It is sectional drawing of the outward path side of the belt conveyor which consists of embodiment of this invention.

以下に、本発明の実施の形態について、図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の実施形態からなるベルトコンベヤの断面を示す。   FIG. 1 shows a cross section of a belt conveyor according to an embodiment of the present invention.

このベルトコンベヤは、無端状のコンベヤベルト１と、そのコンベヤベルト１の下方にベルト幅方向に直列に配置された回転自在な３台のローラー２とを備えている。コンベヤベルト１は、図示しない一対の回転駆動するプーリーに掛け回されており、搬送面３に載置された運搬物を搬送するようになっている。３台のローラー２は、コンベヤベルト１が幅方向に湾曲するように、両端の２台がベルト幅方向の内側へ向けて傾斜している。これら３台のローラー２は、コンベヤベルト１の長手方向に所定の間隔をおいて複数組が設置されている。   The belt conveyor includes an endless conveyor belt 1 and three rotatable rollers 2 arranged in series in the belt width direction below the conveyor belt 1. The conveyor belt 1 is wound around a pair of pulleys (not shown) that is driven to rotate, and conveys a transported object placed on the conveying surface 3. The three rollers 2 are inclined toward the inner side in the belt width direction so that the conveyor belt 1 is curved in the width direction. A plurality of sets of these three rollers 2 are installed at predetermined intervals in the longitudinal direction of the conveyor belt 1.

このようなベルトコンベヤにおいて、コンベヤベルト１の裏面４におけるローラー２と対向する位置には、薄板状の反磁性体５が埋設されていると共に、それぞれのローラー２の内部には磁石６が設置されている。   In such a belt conveyor, a thin diamagnetic material 5 is embedded at a position facing the roller 2 on the back surface 4 of the conveyor belt 1, and a magnet 6 is installed inside each roller 2. ing.

このように構成したことにより、反磁性体５と磁石６の反発力によりコンベヤベルト１を浮上させて、ローラー２との摩擦抵抗を抑えることができるため、ベルトコンベヤの運転動力を省力化することができる。また、反磁性体５は強い外部磁場に対してのみ反磁性を示すため、ベルトコンベヤの近傍に鉄などの強磁性体が存在するような場合でも、コンベヤベルト１が影響を受けることはない。そのため、ベルトの蛇行や偏走行の発生を防ぐことができる。更に、鉄製治具などを用いてのコンベヤベルト１の取付作業やメンテナンスに支障をきたすことはない。   By configuring in this way, the conveyor belt 1 can be lifted by the repulsive force of the diamagnetic body 5 and the magnet 6 and the frictional resistance with the roller 2 can be suppressed, so that the operating power of the belt conveyor can be saved. Can do. Further, since the diamagnetic material 5 exhibits diamagnetism only with respect to a strong external magnetic field, the conveyor belt 1 is not affected even when a ferromagnetic material such as iron exists in the vicinity of the belt conveyor. Therefore, it is possible to prevent occurrence of belt meandering and uneven running. Furthermore, there is no problem in the installation work and maintenance of the conveyor belt 1 using an iron jig or the like.

反磁性体５は、図１に示すように、コンベヤベルト１の幅方向に所定の間隔をおいて別々に装着する代わりに、幅方向の全域に渡って装着するようにしてもよい。このことは、コンベヤベルト１の長手方向においても同様である。   As shown in FIG. 1, the diamagnetic material 5 may be mounted over the entire width direction instead of being separately mounted at a predetermined interval in the width direction of the conveyor belt 1. The same applies to the longitudinal direction of the conveyor belt 1.

反磁性体５をコンベヤベルト１の裏面４に装着する方法としては、上述したように反磁性体５をバインダーで薄板状に固めたものを埋設する方法の他に、粉末状にした反磁性体５を溶剤と共に塗布する方法、バインダーで薄板状に固めた反磁性体５を接着する方法、あるいはコンベヤベルト１の製造段階でベルト裏側のカバーゴム層に反磁性体５を混入する方法などがある。   As a method of mounting the diamagnetic material 5 on the back surface 4 of the conveyor belt 1, as described above, in addition to the method of embedding the diamagnetic material 5 which is solidified with a binder, the powdered diamagnetic material is used. There are a method of applying 5 together with a solvent, a method of adhering the diamagnetic material 5 hardened to a thin plate with a binder, or a method of mixing the diamagnetic material 5 into the cover rubber layer on the back side of the belt at the manufacturing stage of the conveyor belt 1. .

反磁性体５としては、ビスマス、グラファイト及び銅などが例示されるが、コスト及び取扱性の観点から、グラファイトを用いることが望ましい。   Examples of the diamagnetic material 5 include bismuth, graphite, and copper. From the viewpoint of cost and handling properties, it is desirable to use graphite.

磁石６としては、永久磁石又は電磁石を用いることができる。前者の永久磁石を用いる場合には、磁石６のメンテナンスを省略することができる。この永久磁石には、磁力が大きいという理由から、ネオジム磁石が好ましく用いられる。また、後者の電磁石を用いる場合には、磁力の発生及び大きさを制御できるため、仕様の異なるコンベヤベルト１に対応することができると共に、運転休止時におけるコンベヤベルト１の取り扱いを容易にすることができる。   As the magnet 6, a permanent magnet or an electromagnet can be used. When the former permanent magnet is used, maintenance of the magnet 6 can be omitted. As this permanent magnet, a neodymium magnet is preferably used because of its high magnetic force. In addition, when the latter electromagnet is used, the generation and magnitude of the magnetic force can be controlled, so that it is possible to cope with the conveyor belt 1 having different specifications and to facilitate the handling of the conveyor belt 1 during the operation stop. Can do.
