Abstract
Description
タイヤ製造装置の具体的な構成としては、機械本体から水平に延長し、モータの駆動により回転するドラムシャフトと、ドラムシャフトに設けられ、台タイヤ内に空気を注入可能に台タイヤを保持するリム組立て体と、上下2列に配置された複数のローラが突出する棒状体を円周上に均等に複数配置し、かつ棒状体が同期して拡縮するトレッド拡径手段と、トレッド押さえと、トレッド拡径手段とトレッド押さえをリム組立て体方向に移動させる移動機構とを備え、複数の棒状体に円環状トレッドの内径部分を拡径保持し、リム組立て体に台タイヤを固定し、トレッド拡径手段により拡径されたトレッドを台タイヤに対して所定の位置に移動させた後に、トレッドを接近させるように棒状体を台タイヤの周面に当接させ、トレッド押さえでトレッドを台タイヤに押し付け保持し、棒状体を引き抜くことで、台タイヤとトレッドとを一体化する。
さらに、トレッド拡径装置には、棒状体の進退を制御するためのセンサが設けられ、トレッドを棒状体に配置するときに、センサを通過するトレッドの両端部を検出してトレッドの幅方向中心を計算し、各棒状体によりトレッドが保持されるそれぞれの位置を検出し、これに基づいて各棒状体を個別に進退させて、各棒状体の所定位置にあらかじめ設けられた位置決め部材にトレッドの端部が接触するようにしてトレッドをトレッド拡径装置に対して整列するようにさせている。
図1は、タイヤ製造装置1の全体概略図であって、同図に示すようにタイヤ製造装置1は概略、台タイヤ10を固定する台タイヤ保持装置2と、台タイヤ10の外径よりも小さな内径であらかじめ加硫,成型された円環状トレッド(以下、トレッドと記す)11を拡径するトレッド拡径装置3と、台タイヤに組み付けられたトレッド11の表面を押圧する押圧装置4と、トレッド11を台タイヤ10に組み付ける制御を行う制御装置5とを備える。これら各装置は、搭載面が水平に形成された基台6上に搭載される。以下、各装置2乃至5について順を追って説明する。なお、円環状トレッドは、台タイヤの外径よりも小さな内径としたが、台タイヤの外径と同じ、若しくは大きくても良い。
台タイヤ保持装置2は、保持装置本体21と、保持装置本体21の内部から外部に水平方向に延長するドラムシャフト22と、ドラムシャフト22を回転させるドラムモータ24と、保持装置本体21に内蔵されるコンプレッサ25と、ドラムシャフト22の先端部に固着されるドラム23と、CCDカメラ27及び投光器28とからなる台タイヤ中心検出手段26を備える。保持装置本体21は、基台6の長手方向Eの一側側に搭載され、ドラムシャフト22が長手方向Eに貫通する。ドラムシャフト22は、保持装置本体21に固定される図外の軸受けにより回転可能に支持される。ドラムシャフト22の先端にはドラム23が取り付けられ、他端にはプーリ29が取り付けられる。
台タイヤ保持装置2のドラム23とトレッド拡径装置3との間には、図2に示すドラムシャフト22の回転する中心軸Aと平行な一対のレール8,8が基台6上に敷設される。トレッド拡径装置3は、レール8,8上をドラム23に対して近接又は離間する方向に移動可能な車輪9aを備えた台座9上に設置される。トレッド拡径装置3は、拡径装置本体45と拡径手段46と保持手段47とトレッド幅中心検出手段48と移動手段49とにより構成される。拡径装置本体45は、主たる構成として、回転主軸51と円板部52とトレッド回転モータ53とを備える。回転主軸51は、拡径装置本体45の内部から外部へと水平に延長する軸体であって、中心軸Bがドラムシャフト22の中心軸Aと同軸となるように拡径装置本体45内に設けられた図外の軸受けにより支持される。つまり、トレッド拡径装置3の中心軸Bと台タイヤ保持装置2のドラムシャフト22の中心軸Aとは、軸心が一致する。
拡径手段46は、リニアレール57とリニアレール57上をスライドするスライダ58とにより構成される。リニアレール57は、取付面54aの中心から放射状に延長するレール体であって、円板部52の周方向に沿って等しい間隔で敷設される。リニアレール57は、リニアレール57の延長方向に延長する回転ボルトを備え、当該回転ボルトに対応するナットをスライダ58が有することにより、ボルトナット機構を構成し、リニアレール57の端部に取着された回転ボルトを回転させるサーボモータ66が駆動することにより、スライダ58がリニアレール57に沿って円板部52の径方向にスライド可能である。なお、本例において、拡径手段を構成するリニアレール57及びスライダ58を10組としたがこの数に限らず、8組や12組としても良い。また、拡径手段をリニアレール57により構成したが、リンク機構等により構成しても良い。また、スライダ58には、保持手段47が取り付けられる。
図4(a),(b)に示すように、保持手段47は一端がスライダ58に固定され、円板部52の取付面54aから突出するようにドラム23側へと延長する爪部55と、爪部55の延長方向に沿って掛け渡される搬送手段としてのコンベアベルト73とを備える。爪部55は、スライダ58上からドラム23に向かって水平に延長する一対の長枠71,71と、長枠71,71の間において、長枠の延長方向に沿って所定間隔をもって回転可能に支持される複数のタイミングホイール72とを備える。長枠71,71は、取り付け対象たるトレッド11の幅よりも十分長い長さで形成され、複数のタイミングホイール72の回転軸72aを支持する複数の保持孔71aを有する。保持孔71aのうち、ドラム23と最も近い位置にある保持孔71aは、取り付けられるタイミングホイール72の一部が長枠71,71の先端から露出する位置に開設される。また、保持孔71aの中心は、長枠71,71の厚み方向の中心線Hよりも、一方にオフセットするように形成され、取り付けられるタイミングホイール72の一部が長枠71,71の上面から露出する。
トレッド幅中心検出手段48は、例えば、CCDカメラ75と投光器76とにより構成される。図3(a)に示すように、CCDカメラ75と投光器76は、拡径装置本体45から水平方向に延長されるアーム77の先端に取り付けられる。CCDカメラ75は、撮像中心W5が爪部55の延長方向の中心W3と一致するように配置される。また、投光器76は、爪部55の延長方向と平行な帯状光を爪部55で保持可能なトレッド11の最大幅MWよりも幅広の範囲にCCDカメラ75の下方から照射する。
上記構成により、トレッド11の幅方向中心W4に形成され、トレッド11の周方向に連続する凹凸や着色線、例えば白線を後述の制御装置5で検出するために、爪部55に掛け渡されたトレッド11の幅方向に照射された帯状光を撮像し、後述の制御装置5に撮像画像を出力する。なお、トレッド幅中心検出手段48をCCDカメラ75と投光器76により構成したが、これに限定されず、例えば、検出する幅方向中心W4が立体的なトレッドパターンの一部のときには、2次元形状センサによりトレッド11の幅方向断面形状を検出し、幅方向断面からトレッド11の幅方向中心W4を検出すれば良い。
制御装置5は、記憶部15と制御部16と演算処理部17を備え、トレッド11と台タイヤ10との組み付けを制御する。制御装置5には、操作パネル、ドラム23の拡縮機構であるエアシリンダ、内圧保持手段32としてのコンプレッサ25、ドラムモータ24、トレッド拡径装置3のトレッド回転モータ53、拡径手段46のサーボモータ66、保持手段47のサーボモータ74、回転角センサ65、台タイヤ中心検出手段26のCCDカメラ27及び投光器28、トレッド幅中心検出手段48のCCDカメラ75及び投光器76、トレッド拡径装置3を台タイヤ保持装置2方向に近接又は離間させる移動手段49、台タイヤ10に組み付けられたトレッド11を押しならす押圧装置4が接続される。
記憶部15は、トレッド11の種類やサイズ、台タイヤの構造やサイズ、トレッド11と台タイヤ10との組合せパターンに関する情報をあらかじめ記憶する。制御部16は、トレッド11と台タイヤ10の組み付け全般を制御する。
演算処理部17は、台タイヤ中心検出手段26により検出される台タイヤ10の幅方向中心W2とトレッド11の幅方向中心W4とのズレ量を演算し、台タイヤ10の幅方向中心W2とトレッド11の幅方向中心W4とが一致するように移動手段49の移動量を計算する。また、トレッド拡径装置3が台タイヤ保持装置2から離間する速度に対応して、トレッド11を台タイヤ10に組み付けるときのコンベアベルト73の回転速度を算出する。
制御部16は、操作パネルから入力された台タイヤ10の情報に基づき、台タイヤ10のサイズに合うように、ドラム23の拡縮機構であるエアシリンダに対して保持信号を出力し、台タイヤ10の内径に沿うようにドラム23を拡縮動作させる。
また、制御部16は内圧保持手段32に対して、ドラム23に固定された台タイヤ10に所定の内圧となるようにコンプレッサ25からの空気を供給する内圧供給信号を出力する。
図7に示すように、台タイヤ10とトレッド11との組み付けは、まず、台タイヤ10をドラム23の周面上にセットし、トレッド11を複数の爪部55に掛け渡す。
次に、操作パネルから台タイヤ10のタイヤサイズ及びトレッド11種別等の情報を入力する。制御装置5は、ドラム23を拡径させて、コンプレッサ25に蓄えられた空気を台タイヤ10に供給する内圧供給信号をドラム23に出力して、台タイヤ10をドラム23に固定する。
次に、制御装置5は、トレッド回転モータ53にトレッド回転信号を出力して円板部52を回転させ、さらにCCDカメラ75にトレッド幅中心検出信号を出力して回転するトレッド11の表面を撮像する。CCDカメラ75により取得され、出力される撮像画像に基づき、制御装置5は、トレッド11のマーカーに相当する位置、つまり、トレッド11の幅方向中心W4を検出し、当該幅方向中心W4と各爪部55の延長方向の中心W3とのズレ量を演算して算出する。さらに、制御装置5、位置ズレ量が検出されたときの回転角センサ65により検出されるドラム23の角度と、位置ズレ量とを対応させて記憶し、ズレ量に対応した角度に位置する爪部55のサーボモータ74を駆動することでコンベアベルト73を回転させて、トレッド11の幅方向中心W4を爪部55の延長方向の中心W3に位置するように、各爪部55のコンベアベルト73を制御する。これにより、トレッド11が爪部55の延長方向の中心W3の位置に整列した状態で保持される。
トレッド11が爪部55に対して整列した状態で保持されると、制御装置5は移動手段49に位置合わせ信号を出力し、トレッド拡径装置3を台タイヤ保持装置2のドラム23に対して近接する方向に移動させ、トレッド11がドラム23上にセットされた台タイヤ10の周囲を囲繞する位置で停止させる。
次に、CCDカメラ27が、トレッド11の幅方向中心W4と台タイヤ10の幅方向中心W2とのズレ量を検出するために撮像を開始し、撮像画像を出力する。なお、台タイヤ10の幅方向中心W2は、最初の台タイヤ10の固定時に検出された位置を記憶しているので、実際は、トレッド11の幅方向中心W4のみを検出している。CCDカメラ27により取得されたトレッド11の表面の画像から、制御装置5は、トレッド11の幅方向中心W4を示す凹凸部を検出して、あらかじめ記憶している台タイヤ10の幅方向中心W2の位置とのズレ量を検出し、検出されたズレ量に基づいて移動手段49を駆動して台タイヤ10に対するトレッド11の位置を調節して、トレッド11の幅方向中心W4と台タイヤ10の幅方向中心W2とを一致させる。
次に、制御装置5は、移動手段49に離間信号を出力してトレッド拡径装置3を後退させるとともに、爪部55のサーボモータ74に組み付け信号を出力して、トレッド拡径装置3の後退速度に対応させてトレッド11を台タイヤ10の周面上に載せるようにコンベアベルト73を回転させる。つまり、トレッド拡径装置3がドラム23から離間する速度と、コンベアベルト73がトレッド11を搬送する速度とが同じになるように爪部55のサーボモータ74に組み付け信号を出力する。これにより、トレッド11は、相対的に静止した状態で台タイヤ10に対して組み付けられる。
次にトレッド11が組み付けられた台タイヤ10に異常がないか検査するため、ドラムモータ24に回転開始信号を出力し、さらに、CCDカメラ27により組み付けられたトレッド11の表面を周方向に撮像する。CCDカメラ27により撮像された撮像画像によって、トレッド11の幅方向中心W4の左右のブレ量と、トレッド11の幅方向中心W4と制御装置5にあらかじめ記憶された台タイヤ10の幅方向中心W2とのズレ量を制御装置5により検出し、ブレ量及びズレ量が所定の範囲内のときには正常と判定し、異常のときは、操作パネルにエラーを出力し、例えば作業員によりドラム23から台タイヤ10ごと取り外され廃棄される。
以上の工程により、台タイヤ10に対するトレッド11の組み付けが完了する。
特に、トレッド拡径装置3が、トレッド拡径装置3の爪部55に掛け渡されたトレッド11の幅方向中心W4を検出するトレッド幅中心検出手段48を備えたことにより、トレッド拡径装置3の各爪部55の延長方向の中心W3とトレッド11の幅方向中心W4とが一致するようにコンベアベルト73を個別に制御し、円板部52の円形面56と平行になるようにトレッド11を整列させることが可能となり、作業者はトレッド11を複数の爪部55に掛け渡すだけで済む。
また、トレッド11が円板部52の円形面56と平行に整列した状態で爪部55に保持されたことで、トレッド11を台タイヤ10に組み付ける際に、トレッド拡径装置3を移動させるだけで、台タイヤ10の幅方向中心W2とトレッド11の幅方向中心W4とを一致させることができる。
さらに、台タイヤ10にトレッド11を組み付けるときには、台タイヤ10の幅方向中心W2とトレッド11の幅方向中心W4とが一致するようにトレッド拡径装置3を移動させる。そして、台タイヤ10の幅方向中心W2とトレッド11の幅方向中心W4とが一致した状態を保つようにして爪部55を台タイヤ10に当接させた後に、トレッド拡径装置3を台タイヤ10から離間させる。このときの離間する速度と対応するように、各爪部55のコンベアベルト73の各サーボモータ74を同期させて駆動し、トレッド11がその場に静止しているようにコンベアベルト73の回転速度とピストン49bの収縮速度を同調させることにより、台タイヤ10の周面に対してトレッド11の一方の端縁から他方の端縁までを載置することができる。
