本発明の実施形態による線引き装置1を説明する前に、図1を参照して、線材を伸線加工する伸線工程について概略を説明する。図1は、アーク溶接用ワイヤWであるソリッドワイヤやフラックスコアードワイヤ等を、製品として要求される径となるように伸線する伸線工程を示す図である。
なお、本実施形態においては、図2Aにおける正面図に向かっての上下方向を線引き装置1の上下方向に対応付けると共に、同じく正面図に向かっての左右方向を線引き装置1の左右方向に対応付けた位置関係を用いて、線引き装置1の構成を説明する。従って、図2Aの線引き装置1を右側から見たときの側面を右側面図として図2Bに示し、線引き装置1を上側から見たときの側面を上側面図(平面図)として図2Cに示す。また、図2A及び図2Bにおいて、対称軸S1から上半分は線引き装置1の外観を実線で示し、下半分は線引き装置1の内部を破線で示す。
以下、線引き装置1の構成について詳しく説明する。
図2Aの正面図に示すように、枠体3は、ほぼ同じ寸法を有する略直方体形状の4本の鋼材が略正方形又は略長方形の上下及び左右の各辺を構成するように一体となることで構成された部材である。
図2Aに示すように、上述の切欠き部10a,10bを有する(つまり、切欠き面を有する)枠体3は、上梁部6及び下梁部7を上下方向に向けると共に右梁部8及び左梁部9を左右方向に向けると、上下方向及び左右方向に対称な構成を有している。後に詳しく説明するが、図2Aに示す枠体3に他の構成部材を設けることで構成される線引き装置1も、枠体3の下半分に設けられる構成部材と同じ構成部材が上半分にも設けられるので、対称軸S1に関して上下方向に対称な構成を有している。従って、以下の説明では、枠体3の下半分の構成を詳述した後に、枠体3の下半分に設けられる構成部材を詳述することで、線引き装置1の全体の説明とする。
右凹部は、右梁部8の左側、つまり枠体3の内周面が取り囲む空間側に形成されており、上方が開放されて切欠き部10aと連続し、左方が開放されて枠体3が取り囲む空間と連続している。つまり、右凹部は、右梁部8の正面から背面側に後退した略四角形の右段差面11a、右段差面11aの右縁を枠体3の正面に接続する右縁面12a、及び右段差面11aの下縁を枠体3の正面に接続する下縁面13aによって形成されている。この右段差面11aは、左縁において枠体3の内周面と連続すると共に、上縁において切欠き部10aの切欠き面と連続する。また、右段差面12aには、内部にネジ山が切られた2つのネジ穴が、右梁部8の長手方向に沿って上下方向に並ぶように形成されている。
また、貫通孔14aよりも枠体3の背面側には、枠体3の外周面から内周面へ枠体3を貫通するもう一つの貫通孔15aが形成されている。この貫通孔15aは、外周面及び内周面において枠体3の正面と背面のほぼ中間に開口を有し、貫通孔15aの内面には、その一部又は全体にわたってねじ山が切られている。
下梁部7の長手方向に沿ったほぼ中央の位置には、外周面から内周面へ下梁部7(枠体3)を貫通する円形の貫通孔である下中央貫通孔17が形成されている。この中央貫通孔17は、枠体3の正面と背面のほぼ中央において、ほぼ対称軸S2に沿って形成されている。
下梁部7は、下中央貫通孔17に関して、下右貫通孔18aとほぼ左右対称となる位置に下左貫通孔18bを形成していると共に、ガイドピン20aとほぼ左右対称となる位置にもうひとつのガイドピン20bを有している。
回転軸4は、ローラダイス2の軸受けとほぼ同径の円筒形状の部材であって、軸心に沿って内部に空洞を有する円筒状の部材であり、ローラダイス2の軸受けに挿入されると共に該軸受けに固定される。これによって、回転軸4は、ローラダイス2を、回転軸4を中心に回転自在となるように支持する。
図4の(a)に示すように、まず、ローラダイス2がハウジング5の凹部内に配置されるように、ローラダイス2を支持する回転軸4をハウジング5の上側面に形成された溝に載置する。
上述の枠体3には、ハウジング5を、ハウジング5に支持された回転軸4の軸心方向(ハウジング5の長手方向)に沿って移動させることで、枠体3に対して位置決めする第1の位置決め手段が設けられる。
右押圧ネジ29aは、枠体3の外周面に形成された開口から貫通孔14aに螺合して右縁面12aの開口から突出することで、右段差面上11aに配置された右押圧片28aを、枠体3が取り囲む空間側に押圧するものである。
第2の位置決め手段は、枠体3側からハウジング5を押す力を加える押し手段と、枠体3側へハウジング5を引く力を加える引き手段とを有する。
このように、右押しボルト32aと左押しボルト32bを有する押し手段は、略直方体形状のハウジング5に対して、ハウジング5の底面である非支持面を、ハウジング5の上側面に向かって押すことで、ハウジング5を上方に移動させることができ、ハウジング5の上側面に支持された回転軸4を、回転軸4の軸心方向に垂直な垂直方向に沿って移動させることができる。
以上の説明は、枠体3の下半分の構成及び枠体3の下半分に設けられる構成部材についての説明であり、本実施形態による線引き装置1の下半分の構成の説明である。上述のとおり、本実施形態による線引き装置1は、上下対称の構成を有しているので、枠体3には、ローラダイス2を支持する回転軸4と一体となって該回転軸4を支持するハウジング5が2組、ローラダイス2の型溝を対向させて一対となって設けられている。
また、本実施形態による線引き装置1は、ハウジング5及びローラダイス2の位置決め以前に、ローラダイス2及び回転軸4を枠体3とは別体のハウジング5と一体化し、その一体化された別体のハウジング5を枠体3に設ける構成となっている。つまり、線引き装置1の組立てにおいて、回転軸4を枠体3に直に組み付ける必要が無いので、線引き装置1の組立てが非常に容易になる。さらに、ローラダイス2の位置決めに際して、ローラダイス2に対する回転軸4の位置を変更する必要が無いので、第1の位置決め手段及び第2の位置決め手段によって、ローラダイス2の位置を非常に容易且つ正確に調整することができる。
その結果、組立に要する時間については、従来の線引き装置が25分~30分程度要するのに対して、本線引き装置は約15分程度であった。本線引き装置は、従来の線引き装置に要する時間の半分程度で組み立てが完了するだけでなく、約15分という短時間で組立てられるので、作業者の熟練をほとんど必要としない線引き装置であるといえる。
次に、調整時間については、本線引き装置と従来の線引き装置、いずれの線引き装置においても1分であり、少なくとも調整に要する時間において差は見られなかった。
このように、回転軸4の位置を直接調整するのではなく、回転軸4を支持するハウジング5の位置を調整することでローラダイス2の位置出しを行うので、回転軸4のたわみや保持不足を回避しながら、容易にローラダイス2の位置出しができる。
本線引き装置は、分解に要する時間においても2分間ほどの短縮を実現した。これは、以下の理由による。本線引き装置の第1の位置決め手段及び第2の位置決め手段による位置出し方法(位置調整方法)では、ローラダイス2の径方向におけるハウジング5の稼動範囲を、回転軸4の直径以上に確保することができる。このように、ハウジング5の稼動範囲を回転軸4の直径以上に確保することにより、枠体3からハウジング5を取り外すことなくローラダイス2を装着した回転軸4をハウジング5から取り外すことができるからである。また、同様に、ハウジング5も枠体3を分解することなく枠体3から取り外すことができるからである。
例えば、図2Aに示す構成の線引き装置1において、上側のハウジング5に載置された回転軸4の右端に供給口(コネクタ)21を設けると共に、左端に排出口(コネクタ)22を設け、また下側のハウジング5に載置された回転軸4の右端に排出口(コネクタ)22を設けると共に、左端に供給口(コネクタ)21を設けた。その上で、下側の回転軸4の排出口22と上側の回転軸4の供給口21とを、枠体3の右側の切欠き部10aを通る冷却媒体の流通管で直接に接続した。このように上下の回転軸4,4を流通管で接続することで、左側の切欠き部10bを通して下側の回転軸4の供給口21に冷却媒体を供給しつつ、右側の切欠き部10aの流通管を通って下側の回転軸4から上側の回転軸4に流れた冷却媒体を、上側の回転軸4の排出口22から左側の切欠き部10bを通して冷却媒体を排出することができた。
