<第1実施形態>
図1~9に、本発明の第1実施形態に係る光ファイバ融着接続システムを示す。光ファイバ融着接続システム1は、図1及び図2に示すように、融着接続機10と作業台20とを収納箱40に収納した構成である。
本実施形態に係る融着接続機10は、融着接続部11のほか、融着接続後の光ファイバに被せた補強スリーブを加熱する補強スリーブ加熱部12、融着接続機10から作業者向けに種々の情報等を表示する表示器13、条件設定等に用いる操作部14などを有する。また、融着接続機10は、略立方体状の本体部16に融着接続部11、補強スリーブ加熱部12、及び融着接続及び加熱の駆動部及び制御部等の内蔵装置(図示せず)が配置されている。本体部16の下部には複数(例えば4つ)の脚部15が設けられている。表示器13には、液晶、有機EL、または電光式等、各種の表示方式を採用可能である。
融着接続機設置部30は、融着接続機10を支持する底部31と、融着接続機10の後ろ側に設けられた背部32と、底部31及び背部32の左右両側に設けられた一対の側部33,33とを有する。底部31は略矩形状であり、底部31の四辺のうち三方は背部32及び側部33,33により囲まれ、前部は開放されている。
なお、図3には一部しか図示されていないが、突起18a,18b及び案内溝35a,35bは、それぞれ融着接続機10及び融着接続機設置部30の左右両側に設けられている(図6の融着接続機拘束部35,35を参照)。
前処理作業に使用する物品としては、光ファイバ心線を覆う樹脂被覆を除去する光ファイバ被覆除去工具(ストリッパ)、光ファイバ心線に付着した樹脂被覆屑等の塵芥を清掃するためのアルコールを入れたアルコール容器及び拭き取り材(布や紙など)、及び光ファイバ心線を切断する光ファイバ切断機(カッタ)等が挙げられる。
作業面22の寸法は、作業に必要な面積(作業しやすさ)と収納箱の寸法(搬送しやすさ)との兼ね合いで適宜設定すればよく、特に限定されないが、1辺が10~30cmの矩形状、例えば約20cm四方などに設定することができる。
作業台20は、融着接続機設置部30の左右両側(側部33の上端)には、光ファイバ搬送治具(図示せず)を差し込むための固定穴33a,33bを有する。前側に設けられる固定穴33aは融着接続機10の融着接続部11の左右両側に配置され、奥側に設けられる固定穴33bは融着接続機10に内蔵された補強スリーブ加熱部12の左右両側に配置されている(図6も参照)。融着接続作業をする際、あらかじめ前側に設けられる固定穴33aに光ファイバ搬送治具を固定し、融着接続後に光ファイバを光ファイバ搬送治具に把持等により取り付ける。光ファイバ搬送治具を持って前側の固定穴33aから外し、奥側の固定穴33bに移動させると、融着接続後の未補強の光ファイバを容易に補強スリーブ加熱部12に移動(搬送)させることができる。これにより、光ファイバの先端同士が接続された接続点への損傷を確実に防ぐことができる。この場合、光ファイバ搬送治具は、融着接続機10の融着接続部11から補強スリーブ加熱部12へ融着接続後の光ファイバを搬送する際に用いられる。
また、作業台20は、補強スリーブで補強された接続後の光ファイバを設置するための光ファイバ設置台32aを有する。図示例の光ファイバ設置台32aは、例えば断面がU字型のへこみ(溝)を背部32の上端に設けた構成である。
図2に示すように、融着接続機10は、作業台20の融着接続機設置部30に装着した状態で、収納箱40に収納される。
収納箱40は、融着接続機10を装着した作業台20が収納される箱本体50と、箱本体50の上部を覆う蓋70とを有する。融着接続機10等を保護するための衝撃緩衝機能を持たせるため、収納箱40は、次のような構成を有する。
同様に、箱本体内層61は、底部62及び底部62の周囲に立設された(底部62に略垂直に設けられた)側壁部63を有する。底部62は略矩形状であり、側壁部63は、前壁63aと、前壁63aに対向する後壁63bと、前壁63a及び後壁63bの両端の間を塞ぐ一対の端壁63c,63cとを有する。箱本体外層51と箱本体内層61とは、底部52と底部62、前壁53aと前壁63a、後壁53bと後壁63b、及び端壁53cと端壁63cがそれぞれ接するように嵌合される。
箱本体外層51と作業台20との間に合成樹脂発泡体から構成される箱本体内層61が介在することにより、箱の外側から作業台20へ伝わる衝撃を減衰させることができる。なお、箱本体内層61において、すべてが合成樹脂発泡体で形成されている必要はなく、少なくとも一部が合成樹脂発泡体で形成されていればよい。また、少なくとも作業台嵌合部65が合成樹脂発泡体で形成されていることが好ましい。
具体的には、箱本体内層61は、作業台嵌合部65において、箱本体内層61を構成する合成樹脂発泡体が作業台20と接触する凸部66と、前記合成樹脂発泡体が作業台20と接触しない凹部67とを有する。図6に示す例では、凸部66は前壁63aに2箇所、後壁63bに3箇所、前壁63a又は後壁63bと端壁63cとの隅に4箇所形成され、各凸部66の間に凹部67が形成されている。これらの凸部66は、作業台20と箱本体外層51の側壁部53との間に介在され、横揺れ等の衝撃があっても収縮して、作業台20と箱本体外層51とが接触することを防いでいる。
これらの切欠部54,64により、融着接続機10の側面に表示器13を有する場合でも、融着接続機10を箱本体50に収納したまま、作業者が表示器13を見ることができる。側面の表示器13は固定式でもよいが、可動式であっても表示器13の移動を妨げない。具体的には、箱本体50及び作業台20の形状は、表示器13の表示面を表示面に対して垂直方向に延長した空間領域に干渉しないような形状とすることが好ましい。融着接続機の表示器が融着接続機の上面にある場合など、表示を目視するための空間領域に干渉しない場合は、箱本体の切欠部を省略することが可能である。
同様に、蓋内層81は、天部82及び天部82の周囲に形成された側壁部83を有する。天部82は略矩形状であり、側壁部83は、前壁83aと、前壁83aに対向する後壁83bと、前壁83a及び後壁83bの両端の間を塞ぐ一対の端壁83c,83cを有する。蓋外層71と蓋内層81とは、天部72と天部82、前壁73aと前壁83a、後壁73bと後壁83b、また端壁73cと端壁83cがそれぞれ接するように嵌合される。
蓋外層71の前壁73aには、蓋内層81の前壁83aの溝83d(図29参照)と嵌合可能なリブ73dとが設けられている。リブ73dと溝83dとは垂直(上下)方向に延びており、蓋外層71の強度を増すことができる。
蓋外層71と作業台20との間に合成樹脂発泡体で構成される蓋内層81が介在することにより、箱または蓋の外側から作業台20へ伝わる衝撃を減衰させることができる。
融着接続機10を融着接続機設置部78に設置したとき、融着接続機10の脚部15(図3参照)を受ける凹み状の受け座78aが、融着接続機設置部78(ここでは四隅)に形成される。
上述したように本実施形態では箱本体50は切欠部54,64(図5参照)を有するが、蓋70は、箱本体50の切欠部54,64と嵌合可能な突出部74,84(図8及び図9参照)とを有する。突起56と溝76との嵌合による嵌合部46は、箱本体外層51の切欠部54及び蓋外層71の突出部74の縁にも形成されている。これにより、図1に示すように箱本体50に対して隙間無く蓋70を閉じることができ、収納箱40の側面の防水性も確保することができる。
蓋内層81は、融着接続機10が収容される融着接続機収容凹部85と、第1の付属物品収納部43を確保する物品収納凹部86とを有する。
また、作業台20は、第2の付属物品収納部44と融着接続機10との間に隔壁を有する。ここでは、作業台20のうち融着接続機設置部30の側部33が隔壁として機能する。これにより、第2の付属物品収納部44に収納した物品が、融着接続機10に対して衝撃等を与えることを防ぐことができる。
さらに、収納箱40の中から作業台20に設置されている融着接続機10と共に作業台20を取り出すことで、融着接続作業を収納箱40から離れた状態で行うことができる。
また、作業台20を収納箱40から取り出すことなく融着接続機設置部30から融着接続機10のみを取り出すこともできる。これにより、作業場所が狭い場合等、収納箱40の設置に適さない場合でも融着接続作業を行うことが可能になる。
電柱の上または架空電線の近くなど高所作業に際して、作業者がバケット車(クレーンの先にバケットを取り付けたクレーン車)のバケットに乗り込み、光ファイバ融着接続システムを持ち込んで融着接続作業をする場合のように、振動がある環境でも合成樹脂発泡体により振動を遮断し、融着接続機10を保護することができる。
収納箱40に収納した作業台20は、地面(床面)から比較的高い位置にあるため、作業台を特別に設置したり固定したりする作業を要せず、収納箱40を地面(床面)に置いてそのままの状態で融着接続作業が可能である。
収納箱の底面に4本の足が設けられる場合、作業する地面が傾いていたり、平面でなかったりしても、作業台が滑り出すことなく安定した融着接続作業が可能である。
図10~21に、本発明の第2実施形態に係る光ファイバ融着接続システムを示す。光ファイバ融着接続システム101は、図10及び図11に示すように、融着接続機110と作業台120とを収納箱140に収納した構成である。第2実施形態について、第1実施形態に対応する構成には、同じ名称を付し、重複する説明を省略又は簡略化する場合がある。
底部131は略矩形状であり、底部131の四辺は背部132、側部133,133及び前部134により囲まれている。作業トレイ121の一辺に設けられた連結部124を、前部134の切欠部134aに係合させることにより、作業トレイ121と融着接続機設置部130とを連結することができる。
具体的には、押さえプレート136を融着接続機設置部130から外した状態で図19の下向き矢印(1)に示すように融着接続機110を背部132に押し当てながら装着した後、矢印(2)に示すように融着接続機110を前側に移動させる。(1)の段階では、融着接続機110の後側突起部117が融着接続機設置部130の側部133内側の後側突起部137と背部132の間のスペース137aを通り、底部131に設置される。
(2)の段階では、融着接続機110の後側突起部117及び前側突起部118が融着接続機設置部130の側部133内側の後側突起部137及び前側突起部138の下側に入り込む。最後に下向き矢印(3)に示すように押さえプレート136を背部132と融着接続機110との間に挿入することで、融着接続機110が拘束される。
なお、融着接続機設置部130の後側突起部137は、図19では片側のみに示されているが、前側突起部138.138と同様に、後側突起部137は側部133,133の両方に形成されている。融着接続機110の後側突起部117及び前側突起部118も同様に、融着接続機110の両方の側部116,116にそれぞれ形成されている。
また、図16及び図53A及びBに示すように、押さえプレート136の上部には、補強スリーブ加熱部112で補強された接続後の光ファイバを設置するための光ファイバ設置台136aを有する。図示例の光ファイバ設置台136aは、例えば断面がU字型のへこみ(溝)を押さえプレート136の上部136bに設けた構成である。
図11に示すように、融着接続機110は、作業台120の融着接続機設置部130に装着した状態で、収納箱140に収納される。収納箱140は、第1実施形態と同様に、融着接続機110を装着した作業台120が収納される箱本体150と、箱本体150の上部を覆う蓋170とを有する。融着接続機110等を保護するための衝撃緩衝機能を持たせるため、収納箱140は、第1実施形態と同様に、次のような構成を有する。
箱本体外層151は、略矩形状の底部152及び底部152の周囲に立設された(底部152に略垂直に設けられた)側壁部153を有する。同様に、箱本体内層161は、略矩形状の底部162及び底部162の周囲に立設された側壁部163を有する。箱本体外層151と箱本体内層161とは、底部152と底部162、前壁153aと前壁163a、後壁153bと後壁163b、及び端壁153cと端壁163cとがそれぞれ接するように嵌合される。
箱本体150は、少なくとも底部152が、収納箱140の内部に水を浸入させないように防水性を有することが好ましい。
蓋外層171は、略矩形状の天部172及び天部172の周囲に形成された側壁部173を有する。同様に、蓋内層181は、略矩形状の天部182及び天部182の周囲に形成された側壁部183を有する。蓋外層171と蓋内層181とは、天部172と天部182、前壁173aと前壁183a、後壁173bと後壁183b、また端壁173cと端壁183cとがそれぞれ接するように嵌合される。
第1実施形態と同様に、蓋外層171のリブ173dを蓋内層181の溝183d(図42参照)は垂直(上下)方向に延びており、それにより、蓋外層171の強度を増すことができる。
箱本体150と蓋170とは、第1実施形態と同様にヒンジ軸受け155,175(前者は図13及び図14、後者は図17及び図18参照)を組み合わせ、ヒンジ軸142を通して構成した回転ヒンジ141(図36参照)で連結される。
蓋170を開けて融着接続機110または作業台120を使用する際には、図7に示すように蓋を取り外せる構造としてもよい。また、180°以上回転可能な回転ヒンジ等によって、作業の邪魔にならない位置へ蓋を退避させる構造でもよい。
箱本体150の上端と蓋170の下端との間には、第1実施形態と同様に突起156(図13及び図14参照)と溝176(図17及び図18参照)とを組み合わせた嵌合部146(図11参照)が設けられる。嵌合部146は、水漏れ等の原因となる隙間がないように密閉可能に設けられる。
また、作業に必要な物品類を融着接続機110及び作業台120とともに搬送できるようにするため、収納箱140は内部に付属物品収納部を有する。図11では、作業台120の作業面122の上に第1の付属物品収納部143が設けられ、作業面122の下に第2の付属物品収納部144が設けられる。第2の付属物品収納部144は、作業トレイ121の下のみならず、融着接続機設置部130の下にも設けられている。
蓋内層181は、融着接続機110が収容される融着接続機収容凹部185と、第1の付属物品収納部143を確保する物品収納凹部186とを有する。
また、作業台120は、第2の付属物品収納部144と融着接続機110との間に隔壁を有する。ここでは、融着接続機設置部130の底部131が隔壁として機能する。これにより、第2の付属物品収納部144に収納した物品が、融着接続機110に対して衝撃等を与えることを防ぐことができる。
さらに、収納箱140の中から作業台120に設置されている融着接続機110と共に作業台120を取り出すことで、融着接続作業を収納箱140から離れた状態で行うことができる。また、作業台120を収納箱140から取り出すことなく融着接続機設置部130から融着接続機110のみを取り出すこともできる。これにより、作業場所が狭い場合等、収納箱140の設置に適さない場合でも融着接続作業を行うことが可能になる。
電柱の上や架空電線の近くなど高所作業に際して、作業者がバケット車(クレーンの先にバケットを取り付けたクレーン車)のバケットに乗り込み、光ファイバ融着接続システムを持ち込んで融着接続作業をする場合のように、振動がある環境でも、合成樹脂発泡体により振動を遮断し、融着接続機110を保護することができる。
収納箱140に収納した作業台120は、地面(床面)から比較的高い位置にあるため、作業台を特別に設置したり固定したりする作業を要せず、収納箱140を地面(床面)に置いた状態で融着接続作業が可能である。
収納箱140の底面に4本の足152a(図10及び図11参照)がある場合、作業する地面が傾いていたり、平面でなかったりしても、作業台が滑り出すことなく安定した融着接続作業が可能である。
図22~34に、本発明の第3実施形態に係る光ファイバ融着接続システムを示す。光ファイバ融着接続システム1Aは、融着接続機10と作業台20Aとを収納箱40Aに収納し、収納箱40Aは、箱本体50Aと、その上部を覆う蓋70Aとを有する(図22~26参照)。第3実施形態における作業台20A、収納箱40A、箱本体50A、及び蓋70Aの各部の構成について、第1実施形態に対応する構成には、同じ符号及び名称を付し、重複する説明を省略する場合がある。
さらに本実施形態の場合、図26に示すように、蓋70Aの内側の融着接続機10が収容される融着接続機収容凹部85と作業面22上の物品を収納する物品収納凹部86,86との間がつながっており、作業面22上に物品を収納するスペースをより広く確保することができる。
また、本実施形態の作業台20Aは、それぞれの作業面22,22に物品等を載置可能な凹部26,26を有する。これにより、作業面22上で使用中の物品とその他の物品とを整然と配置することができ、作業性が向上する。
図35~53Bに、本発明の第4実施形態に係る光ファイバ融着接続システムを示す。光ファイバ融着接続システム101Aは、融着接続機110と作業台120Aとを収納箱140Aに収納し、収納箱140Aは、箱本体150Aと、その上部を覆う蓋170Aを有する(図35~39参照)。第4実施形態における作業台120A、収納箱140A、箱本体150A、及び蓋170Aの各部の構成について、第2実施形態に対応する構成には同じ符号及び名称を付し、重複する説明を省略する場合がある。
さらに本実施形態の作業台120Aは、作業面122に物品等を載置可能な凹部126,127を有する。これにより、作業面122上で使用中の物品とその他の物品を整然と配置することができ、作業性が向上する。凹部126は作業面122上に突出して設けられた仕切り126aにより区画され、凹部127は作業面122より低く窪んでいる。
例えば、箱は、箱本体の側壁部の上端と蓋の側壁部の下端とを突き合わせる方式に限られるものではなく、箱本体の上面に水平方向に蓋を差し込む方式、または箱本体の対向する2辺にそれぞれ軸で両開きの蓋を取り付ける方式等を用いてもよい。
融着接続される光ファイバは、光ファイバケーブルから取り出した光ファイバ心線に限られず、光ファイバコード等でもよい。光ファイバ心線としては、石英系ガラスで形成されるコア及びクラッドを有する裸光ファイバの周囲に1層又は2層以上の樹脂被覆を設けた光ファイバ心線が挙げられる。
作業台20の落下防止突起23や側部33は、形状を柵状としたり、杭状の構造物を適当な間隔で列に並べたりしてもよい。
