Abstract
Description
(カーブベルトコンベヤ及びビードガイドの構成)
図1は、本実施形態に係るカーブベルトコンベヤ1の斜視図である。図1に示すように、本実施形態に係るカーブベルトコンベヤ1は、架台10と、2本のエンドローラ11,11と、搬送用ベルト12と、ビードガイド30とを含んで構成されている。カーブベルトコンベヤ1は、図示しない上流側のコンベヤと下流側のコンベヤとの間に設置され、上流側のコンベヤから搬送用ベルト12上に搬送物が送られ、当該搬送物を下流側のコンベヤへと円滑に受け渡す。
本実施形態のビードガイド30は、ビード12bに接触する棒状部32を樹脂で形成したことによって、コンベヤ運転時、棒状部32がビード12bに接触して摺動している際に、ビード12bから与えられた外力に応じて棒状部32が従来よりも一段と柔軟に可動できることから、ビード12bから与えられる負荷を棒状部32において低減でき、その分、ビード12bとの接触箇所における摩耗粉の発生と摺動抵抗とを低減することができる。
(動摩擦係数)
次に、ビードガイド30に用いる樹脂に関して動摩擦係数を測定した。ここでは、ビードガイド30の棒状部32に相当する試験用板材を、樹脂の種類等を変えて製造し、各試験用板材の動摩擦係数について測定した。
次に、ピコ摩耗試験機を使用して、上記の実施例1~3に試験機の刃物を当てて回転させたときの各累計摩耗量を測定した。ここでは、44Nの荷重を印加して60rpmの回転数で、実施例1~3を試験機の刃物を当てて回転させ、正方向及び逆方向に交互に20回転ずつ、総計で80回転を1セットとし、3セット試験を行ったときの累計の摩耗量を測定した。
次に、上記の実施例2と同じフッ素入りPOMにより棒状部と支持部と高さ調整部とを一体成形したビードガイド(実施例4)を用意した。また、金属製の棒状部基体をポリテトラフルオロエチレンで被覆した棒状部と、樹脂製の支持部と、金属製の高さ調整部とを別体とし、これらを組み立てた従来のビードガイド(比較例2)を用意した。そして、試験用のカーブベルトコンベヤに実施例4及び比較例2のビードガイドを設定し、長時間運転したときのビード及びビードガイドの摺動部分の摩耗量の時間変化を測定した。
次に、上述した実施例4及び比較例2のビードガイドについて、上記の摩耗量の時間変化の測定において、同時に電流値の時間変化についても測定したところ、図10に示すような結果が得られた。
なお、上述した実施形態においては、図2及び図3に示すように、棒状部32の周面と高さ調整部33の壁面33aとの間に段差がなく平面状に形成されたビードガイド30を適用した場合について述べたが、本発明はこれに限らない。他の実施形態に係るビードガイドとして、例えば、図11に示すように、棒状部32の周面と高さ調整部33の壁面33aとの間に段差が形成されたビードガイド30Xを適用してもよい。
上述した実施形態においては、ビードガイドとして、支持部31と棒状部32と高さ調整部33とが樹脂により一体成形されたビードガイド30を適用した場合について述べたが、本発明はこれに限らず、棒状部が樹脂からなるビードガイドであれば、種々の形状及び構成を有したビードガイドを適用してもよい。
