Abstract
Description
本願は、2012年10月31日に、日本に出願された特願2012-240521号に基づき優先権を主張し、その内容をここに援用する。
しかしながら、上述したタイヤの電気抵抗の低い材質は、サイズや形状などの仕様や、製造上のずれ等によって配置が異なることが多い。また、上述したタイヤの電気抵抗の低い材質は、目視では判断できない場合がある。そのため、タイヤの電気抵抗の検査を自動化しようとする場合に、検査対象となるタイヤのトレッド部において、電気抵抗の低い材質が配置される箇所を確認して、外周側の測定子の位置や角度を変更するなど調整工程が必要となり作業者の負担が増加する。
この発明は、仕様の異なる被測定タイヤに対して、測定子の調整を行うことなしに安定的に電気抵抗を測定することができるタイヤの電気抵抗測定装置を提供する。
図1は、この実施形態の電気抵抗測定装置1の概略構成を示す構成図である。
図1に示すように、電気抵抗測定装置1は、加硫済みのタイヤTの検査ライン(図示せず)に配置され、タイヤTを搬送するローラコンベア2を有している。ローラコンベア2は、自転可能な複数のローラ3を、搬送方向に複数配列して備えるとともに、ローラコンベア2の幅方向(以下、単に幅方向と称する)の両側に離間して備えている。このローラコンベア2は、タイヤTを、そのサイドウォール4が上下方向を向いた状態で搬送可能となっている。
また、流体圧シリンダー21のインナーロッド23を伸長方向に変位させることで、測定子ユニット6がガイド部17を介してガイド棒16に沿って上方に移動する。これにより測定子ユニット6を、上方すなわちローラコンベア2に近接する方向に移動させることが可能となる。
また、測定子用流体圧シリンダー34を伸長方向に駆動した場合、ガイド棒30に沿って、第一スライド部32および第二スライド部33が離間する方向に相対的に変位する。その結果、外周側測定子5aと内周側測定子5bとが離間する方向に変位する。
例えば、上述した実施形態では、外周側測定子5aとしてコイルばねBを用いる場合について説明したが、タイヤTの幅方向で、トレッド部70のセンター部Cからショルダー部Sに至るタイヤ形状にならって湾曲変形可能であればよく、コイルばねに限られるものではない。例えば、第1変形例として図4A、図4Bに示すように、外周側測定子5aとして可撓性を有した線状の導電体Dを用いても良い。この図4A、図4Bに示す場合も、上述した実施形態と同様に、タイヤTを外周側測定子5aに押し付けることで、トレッド部70の外形にならって湾曲変形可能となる。線状の導電体Dとしては、可撓性を有した針金、ワイヤー、および、少なくとも表面に導電性を有した糸などを用いることができる。
さらに、上述した各実施形態では、内周側測定子5bを傾斜配置する場合について説明したが、鉛直上方に延びるように配置したり、必要に応じて傾斜角度を変更可能にしたりしても良い。
