Description

【０００１】
【産業上の利用分野】
本発明は、基台に曲線軌道レールを組付けし、曲線軌道レール上に転動体を介して摺動体を摺動自在に案内し、摺動体に連結した機器類に円弧運動をさせる曲線案内装置に関する。
【０００２】
【従来の技術】
図１５（ａ）に示すように、従来の曲線案内装置においては、基台（ベース取付面）１上に曲線軌道レール２を組付けし、曲線軌道レール２上に転動体１０を介して摺動体８を摺動自在に案内する。
図１５（ｂ），（ｃ）に示すように、基台１上に曲線軌道レール２を組付する場合には、基台１上の円弧の線上に間隔をおいてピン１１を植設し、短尺曲線軌道レール３を基台１上に静かに置く。これらのピン１１に短尺曲線軌道レール３の内側（図１５（ｂ），（ｃ）では左側）の基準面を当接させ、短尺曲線軌道レール３の端部を連結部（継ぎ部）９で相互に接近させ、必要な間隔をおくことにより所定の軌道長さの曲線軌道レール２を構成する。次に、基台１上で短尺曲線軌道レール３の外側（図１５（ｂ），（ｃ）では右側）の位置に、複数の横押ボルト用ブロック１２を置き、横押ボルト用ブロック１２の螺子孔に螺合された横押ボルト１３の先端を曲線軌道レール２の外側面（反基準面）に当接させる。曲線軌道レール２の段付孔１４に取付ボルトを差し込み、取付ボルトを基台１の螺子孔（予め形成された螺子孔）に軽く螺合させ、曲線軌道レール２を基台１に仮締めする。横押ボルト用ブロック１２を基台１に固定し、曲線軌道レール２の外側の反基準面に横押ボルト１３の先端が平均して密着するように横押ボルト１３をねじ込む。段付孔１４と段付ボルトには「あそび」があり、段付孔１４の中心と段付ボルトの中心をずらして螺合することができる。不図示の測定治具を用いて、曲線軌道レール２の外側角部にダイヤルゲージを当て、その円弧の真円度を測定する。測定した結果、真円度が非常に悪い部分に対しては、短尺曲線軌道レール３を取り外し、再度取り付け直す。こうした作業を繰り返して、曲線軌道レール２の基台１上への正確な位置決めを行い、取付ボルトの締め付けをトルクレンチにより中央から両端に向け順序よく行い、曲線軌道レール２を基台１に固定する。
【０００３】
ＮＣ研削盤等の使用により、精確なレール半径Ｒ・真円度を有する短尺曲線軌道レール３が製作される。従って、短尺曲線軌道レール３を１本だけ使用するときは、円弧の測定（真円度の測定）をすることなく、短尺曲線軌道レール３を基台１に取付ボルトで固定すればよい。しかし、通常は、複数個の短尺曲線軌道レール３を連結した所定の軌道長さの曲線軌道レール２として使用するので、前記のように、基台１上に曲線軌道レール２を組付けする場合に、曲線軌道レール２の組付現場で真円度の測定を繰り返して位置決めを行う必要があり、組付に多くの時間と手数を要した。
【０００４】
【発明が解決しようとする課題】
本発明の課題は、従来の短尺曲線軌道レールをそのまま用いて、曲線案内装置の曲線軌道レールを基台上に組付けする場合に、組付現場において円弧の測定をすることなく、複数の短尺曲線軌道レールを基台上の精確な円弧・レール半径を有する位置に配置して曲線軌道レールとなすことであり、また曲線案内装置の摺動体の駆動を簡易に行うことができるようになすことである。
【０００５】
【課題を解決するための手段】
本発明は、前記課題を達成するために、基台に曲線軌道レールが組付けされ、曲線軌道レール上に摺動体が転動体を介して摺動自在に案内される曲線案内装置において、曲線取付基板には上部に曲線軌道レール締結面が形成され、曲線軌道レール締結面の端部には上方へ突出した突条が形成され、突条の側部に曲線軌道レール締結基準面がそれぞれ形成され（上部突条が曲線取付基板の内側上部に配置されたときは、上部突条の外側に曲線軌道レール締結基準面が形成され、上部突条が曲線取付基板の外側上部に配置されたときは、上部突条の内側に曲線軌道レール締結基準面が形成される。）、短尺曲線軌道レールの端部を相互に連結することにより所定の軌道長さの曲線軌道レールが構成され、基台と曲線軌道レールとの間に曲線取付基板が配設され、曲線軌道レールの側部と曲線取付基板の曲線軌道レール締結基準面とが当接され、曲線軌道レールと曲線取付基板には締結用の挿通孔又は螺合孔が形成され、曲線取付基板の列の端部が短尺曲線軌道レールの列の端部の連結部と重ならない位置に配置され、曲線軌道レールが取付ボルトにより基台に締結されることを技術的手段とする。

▲４▼ 曲線取付基板に段付挿通孔・挿通孔（交互に又は適宜の順序に配置された段付挿通孔及び挿通孔）又は段付挿通孔・螺合孔（交互に又は適宜の順序に配置された段付挿通孔及び螺合孔）が形成され、短尺曲線軌道レールに段付挿通孔が曲線取付基板の挿通孔又は螺合孔に対応する位置に形成され、短尺曲線軌道レールを案内用の治具として曲線取付基板が順次に位置決めされ基板に固定されて、所定の半径の曲線取付基板の列がつくられ、曲線取付基板の列の上部に曲線取付基板の列に沿って短尺曲線軌道レールが順次に固定されるようになすことができ、
▲５▼ 短尺曲線軌道レールに段付挿通孔が形成され、曲線取付基板に挿通孔又は挿通孔・螺合孔（交互に又は適宜の順序に配置された挿通孔及び螺合孔）が形成され、一端から順次に短尺曲線軌道レールと曲線取付基板とが重ねて位置決めされ、短尺曲線軌道レールと曲線取付基板とが締結され又は短尺曲線軌道レールと曲線取付基板と基板とが締結され、所定の半径の曲線軌道レールが組み付けられるようになすことができ、
▲６▼ 曲線取付基板に段付挿通孔・挿通孔（交互に又は適宜の順序に配置された段付挿通孔及び挿通孔）が形成され、短尺曲線軌道レールの裏面に未貫通の螺合孔が開口するように形成され、短尺曲線軌道レールと曲線取付基板とを順次に重ね合わせて位置決めし締結して、所定の半径の第２締結レール複合体が組み立てられ、第２締結レール複合体が曲線軌道レールを上側にして基板に配置され、基板の下面から挿入した取付ボルトを曲線軌道レールの螺合孔に螺合するようになすことができ、
▲７▼ 短尺曲線軌道レールの裏面に未貫通の螺合孔が開口するように形成され、曲線取付基板に段付挿通孔・挿通孔（交互に又は適宜の順序に配置された段付挿通孔及び挿通孔）が形成され、短尺曲線軌道レールを案内用の治具として曲線取付基板を順次に位置決めして基板に固定されて、所定の半径の曲線取付基板の列がつくられ、曲線取付基板の列の上部に曲線取付基板の列に沿って短尺曲線軌道レールが順次に配置され、基板の下面から挿入した取付ボルトを曲線軌道レールの螺合孔に螺合するようになすことができる。
【０００６】
【作用】
基台に組み付けられた曲線軌道レール上に摺動体が転動体を介して摺動自在に案内される。摺動体に連結されたテーブルに回転駆動ユニットが配設され、回転駆動ユニットを駆動すると、駆動力は回転駆動ユニットの回転軸、回転軸に結合された歯車、歯車に噛み合わせられたタイミングベルトの外面又は内面の歯を介してタイミングベルトに伝動される。回転駆動ユニットはタイミングベルトの反作用を受け、テーブルが曲線軌道レールに沿って移動する。
【０００７】
【実施例】
図１〜図１４は本発明の実施例を示し、従来例と同一の部材には図１５と同一の符号を付し、共通の部分については原則としてその説明を省略ないし簡略にする。本発明の実施例において、基台１と曲線軌道レール２の短尺曲線軌道レール３は従来例と同様のものが使用される。本発明の実施例の特徴は、基台１と短尺曲線軌道レール３との間に曲線取付基板４が配設されることである。この曲線取付基板４は、短尺曲線軌道レール３を案内して精確な円弧の曲線軌道レール２を形成するための連結補助具の機能を有し、またタイミングベルトの接合面を提供するものである。
図１〜図５は本発明の第１実施例・第１組付方法を示し、曲線取付基板４は、上面視で曲線軌道レール２と同一半径の円弧形状をなし、断面が略Ｌ字形で内側上方に突条１６が形成され、外側下方に突部５が形成されており、横幅は曲線軌道レール２よりも突条１６及び突部５の幅の長さだけ大きい。曲線取付基板４の上面には曲線軌道レール締結面６があり、曲線軌道レール締結面６の内側端部には上方へ突出した前記突条１６が形成され、突条１６の外側面（図１では右側面）は曲線軌道レール締結面基準面７であり、曲線軌道レール締結面６と曲線軌道レール締結面基準面７とは直角をなす。曲線軌道レール締結面６は曲線軌道レール２を載置し締結するための平面であり、曲線軌道レール締結面基準面７は曲線軌道レール２の内側（図１では左側面）の基準面１８を押し付けて、曲線軌道レール２の位置を決めるための曲面である。曲線取付基板４の底面１７は曲線取付基板４を基台１上に載置するための面であり、曲線軌道レール締結面６と底面１７とは高精度の平行である。突部５は、後述のタイミングベルト４３を載せ、タイミングベルト４３の上下方向のズレを防止するためのものである。他の実施例においては説明を省略する。
【０００８】
図１〜図３には第１実施例の組付後の状態が示されており、図１は図３・図４（ｄ）のＩ−Ｉ線の断面を示し、この断面の位置で、短尺曲線軌道レール３に縦方向に貫通した段付挿通孔１９（大径部が上側）が形成され、曲線取付基板４及び基台１にそれぞれ挿通孔２２及び螺合孔２９が形成されている。曲線軌道レール締結面６上に短尺曲線軌道レール３が載せられ、短尺曲線軌道レール３の内側の基準面１８が曲線軌道レール締結面基準面７に押し付けられ、短尺曲線軌道レール３の位置決めが行われている。短尺曲線軌道レール３の段付挿通孔１９及び曲線取付基板４の挿通孔２２に取付ボルト２１が挿通され、かつ取付ボルト２１が基板１の螺合孔２９にねじ込まれ、短尺曲線軌道レール３と曲線取付基板４とが基板１に締結されている。曲線軌道レール２（短尺曲線軌道レール３）上に転動体１０を介して摺動体８が摺動自在に案内される。
図２は図３・図４（ｄ）のＩＩ−ＩＩ線の断面を示し、この断面の位置で、短尺曲線軌道レール３に縦方向に貫通した段付挿通孔１９が形成され、曲線取付基板４に螺合孔２４が形成されている。曲線軌道レール締結面６上に短尺曲線軌道レール３が載せられ、短尺曲線軌道レール３の内側の基準面１８が曲線軌道レール締結面基準面７に押し付けられ、短尺曲線軌道レール３の位置決めが行われている。短尺曲線軌道レール３の段付挿通孔１９に結合ボルト２５が挿通され、結合ボルト２５が曲線取付基板４の螺合孔２４にねじ込まれ、短尺曲線軌道レール３と曲線取付基板４とが連結されている。
【０００９】
図４は第１実施例の曲線案内装置の曲線軌道レールの第１組付（締結）方法を示し、第１組付方法（重ね方式）の特徴は、短尺曲線軌道レール３と曲線取付基板４とを順次重ね合わせて締結し、所定の半径の曲線軌道レール２と曲線取付基板４とからなる締結レール複合体（一条の継ぎレール）２８をつくり、この締結レール複合体２８を基台１の上に載せ、取付ボルト２１で曲線軌道レール２（締結レール複合体２８）を基台１に固定することである。
図１〜図４に示すとおり、短尺曲線軌道レール３には２種の長さのものがあり、Ａタイプの短尺曲線軌道レール３には４個の縦方向の段付挿通孔１９が略等間隔に形成され、Ｂタイプの短尺曲線軌道レール３には８個の縦方向の段付挿通孔１９が略等間隔に形成されている。曲線取付基板４には８個の螺合孔２４又は挿通孔２２が段付挿通孔１９と同様の等間隔で順次に形成されており、図４で左端から１、３、５、７番目に螺合孔２４が、２、４、６、８番目に挿通孔２２がそれぞれ形成されている。
【００１０】
図４（ａ）に示すように、先ず第（１）番目の曲線取付基板４の上に第▲１▼番目のＡタイプの短尺曲線軌道レール３を載せる。第▲１▼番目の短尺曲線軌道レール３の内側の基準面１８を第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させる。この場合、図４（ｅ）に示すＣクランプ２７等を用いると、この作業を簡単に行うことができ、Ｃクランプ２７等を用いることは他の同様の作業のときにも行われる。次に、第▲１▼番目の短尺曲線軌道レール３の１、３番目の段付挿通孔１９に結合ボルト２５を挿通し、第（１）番目の曲線取付基板４の１、３番目の螺合孔２４に結合ボルト２５を螺合させ、第▲１▼番目の短尺曲線軌道レール３と第（１）番目の曲線取付基板４とを締結する。なお、結合ボルト２５は、締結後に結合ボルト２５の先端が曲線取付基板４の下面に突出することのない長さとする。また、短尺曲線軌道レール３の段付挿通孔１９を少し大き目にしておくと、位置決めによって段付挿通孔１９の軸芯と螺合孔２４の軸芯とが多少ずれても、結合ボルト２５を螺合孔２４に螺合することができる。これらの点は、他の同様な締結においても同様である。
【００１１】
第▲１▼番目のＡタイプの短尺曲線軌道レール３と第（１）番目の曲線取付基板４とを締結した場合、曲線取付基板４の長さはＡタイプの短尺曲線軌道レール３の長さの２倍あり、４図（ａ）に示すとおり、曲線取付基板４の右半分の上面が露出した状態となる。そこで、次に図４（ｂ）に示すように、第▲２▼番目のＢタイプの短尺曲線軌道レール３を第（１）番目の曲線取付基板４の右半分の上に載せる。図４（ａ）の場合と同様に、第▲２▼番目の短尺曲線軌道レール３の左半分の内側の基準面１８を第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲２▼番目の短尺曲線軌道レール３の左半分の基準面１８と第１番目の曲線取付基板４の右半分の曲線軌道レール締結基準面７とが一致し、第▲１▼番目の短尺曲線軌道レール３と第▲２▼番目の短尺曲線軌道レール３が同一半径で連続した円弧となるように位置決めし、その位置に維持させる。次に、第▲２▼番目の短尺曲線軌道レール３の１、３番目の段付挿通孔１９に結合ボルト２５を挿通し、第（１）番目の曲線取付基板４の５、７番目の螺合孔２４に結合ボルト２５を螺合させ、第▲２▼番目の短尺曲線軌道レール３と第（１）番目の曲線取付基板４とを締結する。
【００１２】
同様にして、図４（ｃ）に示すように、第（２）番目の曲線取付基板４、第▲３▼番目のＢタイプの短尺曲線軌道レール３、第（３）番目の曲線取付基板４───第ｎ−１番目のＢタイプの短尺曲線軌道レール３、第（ｎ）番目の曲線取付基板４、第ｎ番目のＡタイプの短尺曲線軌道レール３の順に締結する。このように短尺曲線軌道レール３と曲線取付基板４とを順次に締結して、所定の半径の円弧を有する曲線軌道レール２と曲線取付基板４の列との締結レール複合体２８が組み立てられる。短尺曲線軌道レール３と曲線取付基板４との締結は、どの組み合わせにおいても２個の結合ボルト２５を用いているので、締結レール複合体２８は曲線軌道レール２と曲線取付基板４の列とが確実に締結されており、通常の取扱をしても締結レール複合体２８の形状が変化することはない。この締結レール複合体２８を基板１の上に載せて、固定すれば曲線軌道レール２の組付ができるが、高精度の円弧が要求されている場合には、締結レール複合体２８の円弧の真円度を測定し、測定結果に従って手直しすることもできる。
【００１３】
図４（ｄ）は締結レール複合体２８を基板１に固定した状態が示されている。基板１上で所定の位置（挿通孔２２と略一致する位置）に挿通孔２２と同一数の螺合孔２９を形成する。締結レール複合体２８を基板１の所定の位置、すなわち挿通孔２２と螺合孔２９とが略同一軸芯となる位置に置き、締結レール複合体２８を仮締めして動かないようにする。取付ボルト２１を曲線軌道レール２の左端から偶数番目の段付挿通孔１９及び曲線取付基板４の挿通孔２２を挿通させ、螺合孔２９にねじ込む。このようにして締結レール複合体２８の基板１への固定が行われる。上記のように、短尺曲線軌道レール３相互の連結部９と曲線取付基板４相互の継ぎ目３０との長手方向の位置はずれており、それらが重なることはない。また、結合ボルト２５・取付ボルト２１のねじ込みに際しトルクレンチを用いて、締付力を略一定にすることが望ましい。（これらの点は他の組付方法においても同様である。）なお、締結レール複合体２８を仮締めして動かないようにした後に、曲線軌道レール２の左端から偶数番目の段付挿通孔１９及び曲線取付基板４の挿通孔２２にドリル等の穿孔器具を挿入し、段付挿通孔１９・挿通孔２２と略同一軸線位置で基板１の表面に所定深さの螺合孔２９を形成することも可能である。
このようにして第１実施例の第１組付方法による曲線案内装置の曲線軌道レールの組付が完了する。第１組付方法の重ね方式は、締結レール複合体２８の作成及び締結レール複合体２８の基板１への固定という２つの作業に大別され、同種の作業が一括して行われるので、後述する他の組付方法に較べて作業効率が極めて高く、比較的短時間で曲線軌道レール２の組付けを行うことができる。なお、短尺曲線軌道レール３と曲線取付基板４の長さ及び孔類の数並びに孔類の間隔は適宜変更することができる。しかし、結合ボルト２５と取付ボルト２１とが交互に配設され、短尺曲線軌道レール３と曲線取付基板４との締結が、どの組み合わせにおいても２個以上の結合ボルト２５を用いることが望ましい。また、第１組付方法において、取付ボルト２１に代え後述の第４組付方法の取付ボルト３８を採用し、取付ボルト３８に関連する孔類を第４組付方法のように変更することができる。
【００１４】
図５は第１組付方法の変形例を示す。この変形例においては、上側の曲線取付基板４と下側の短尺曲線軌道レール３とを順次重ね合わせて締結し、所望の半径の曲線軌道レール２と曲線取付基板４の列とからなる締結レール複合体２８ａをつくる。そして、この締結レール複合体２８ａを基台１の上に載せるときに、締結レール複合体２８ａの上下を逆にして曲線軌道レール２を上側におき、取付ボルト２１で曲線軌道レール２を基台１に固定する。
図５に示すとおり、曲線取付基板４には２種の長さのものがあり、Ｃタイプの曲線取付基板４には４個の縦方向の段付挿通孔５０（組付後には大径部が下側）及び挿通孔２２が交互に略等間隔に形成され、曲線取付基板４の左端から１、３番目に段付挿通孔５０が配置され、２、４番目に挿通孔２２が配置されている。Ｄタイプの曲線取付基板４には８個の段付挿通孔５０及び挿通孔２２が交互に略等間隔に形成され、図５で左端から１、３、５、７番目に段付挿通孔５０が、２、４、６、８番目に挿通孔２２がそれぞれ配置されている。短尺曲線軌道レール３には８個の縦方向の螺合孔５１及び段付挿通孔１９が交互に略等間隔に形成されている。
【００１５】
図５（ａ）に示すように、先ず第▲１▼番目の短尺曲線軌道レール３の左半分の上に第（１）番目のＣタイプの曲線取付基板４を載せる。第▲１▼番目の短尺曲線軌道レール３の内側の基準面１８に第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７を押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させる。次に、第（１）番目の曲線取付基板４の１、３番目の段付挿通孔５０に結合ボルト２５を挿通し、第▲１▼番目の短尺曲線軌道レール３の１、３番目の螺合孔５１に結合ボルト２５を螺合させ、第（１）番目の曲線取付基板４と第▲１▼番目の短尺曲線軌道レール３とを締結する。
【００１６】
次に図５（ｂ）に示すように、第（２）番目のＤタイプの曲線取付基板４を第▲１▼番目の短尺曲線軌道レール３の右半分の上に載せる。図５（ａ）の場合と同様に、第▲１▼番目の短尺曲線軌道レール３の右半分の内側の基準面１８に第（２）番目の曲線取付基板４の左半分の曲線軌道レール締結基準面７を押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の右半分の基準面１８と第（２）番目の曲線取付基板４の左半分の曲線軌道レール締結基準面７とが一致し、第（１）番目の曲線取付基板４と第（２）番目の曲線取付基板４が同一半径で連続した円弧となるように位置決めし、その位置に維持させる。次に、第（２）番目の曲線取付基板４の１、３番目の段付挿通孔５０に結合ボルト２５を挿通し、第▲１▼番目の短尺曲線軌道レール３の５、７番目の螺合孔５１に結合ボルト２５を螺合させ、第（２）番目の曲線取付基板４と第▲１▼番目の短尺曲線軌道レール３とを締結する。
【００１７】
同様にして、図５（ｃ）に示すように、第▲２▼番目の短尺曲線軌道レール３、第（３）番目のＤタイプの曲線取付基板４、第▲３▼番目の短尺曲線軌道レール３、───第（ｎ−１）番目のＤタイプの曲線取付基板４、第ｎ番目の短尺曲線軌道レール３、第（ｎ）番目のＣタイプの曲線取付基板４の順に締結する。このように曲線取付基板４と短尺曲線軌道レール３とを順次に締結して、所定の半径の円弧を有する曲線軌道レール２と曲線取付基板４の列との締結レール複合体２８ａが得られる。前記のとおり、この締結レール複合体２８ａの上下を逆にし、曲線軌道レール２を上側にして基板１に固定する。なお、螺合孔５１が上面に開口し、結合ボルト５０の先端が露出しているので、螺合孔５１を盲蓋で封鎖してもよい。
図５（ｄ）は締結レール複合体２８ａを基板１に固定した状態が示されている。固定の方法は第１組付方法の場合と同じである。また、その余の点も第１組付方法の場合と同様である。
【００１８】
図６は第１実施例の曲線案内装置の曲線軌道レールの第２組付方法を示し、第２組付方法（曲線取付基板継ぎ方式）の特徴は、短尺曲線軌道レール３を案内用の治具にして、基板１の上に複数の曲線取付基板４の端部を連結部を介して連結し、順次に曲線取付基板４を基板１に固定して所望の円弧の曲線取付基板４の列をつくる。次に、この曲線取付基板４の列の上に短尺曲線軌道レール３を載せ、短尺曲線軌道レール３を曲線取付基板４又は基板１に固定するものである。第２組付方法の説明において、第１組付方法と同様の部分には第１組付方法の説明と同一の符号を用い、原則として共通部分の説明は省略する。
図６に示すとおり、短尺曲線軌道レール３には２種の長さのものがあり、Ａ’タイプの短尺曲線軌道レール３には２個の縦方向の段付挿通孔１９が形成され、この段付挿通孔１９は、前記のＡタイプの短尺曲線軌道レール３の２、４番目の段付挿通孔１９に相当する位置にある。Ｂ’タイプの短尺曲線軌道レール３には４個の縦方向の段付挿通孔１９が形成され、この段付挿通孔１９は、前記のＢタイプの短尺曲線軌道レール３の２、４、６、８番目の段付挿通孔１９に相当する位置にある。曲線取付基板４には８個の段付挿通孔３２（外径部が上側）又は挿通孔２２が等間隔で順次に形成されており、図６で左端から１、３、５、７番目に段付挿通孔３２が、２、４、６、８番目に挿通孔２２がそれぞれ形成されている。
【００１９】
基板１上であって曲線取付基板４の段付挿通孔３２・挿通孔２２の下位置となるべき箇所に、螺合孔３４・螺合孔２９を交互に形成しておく。図６（ａ）に示すように、先ず第（１）番目の曲線取付基板４を基板１上の所定の位置に載せ、仮締めして動かないようにする。結合ボルト３３を曲線取付基板４の左端から１、３、５、７番目の段付挿通孔３２に挿通させ、螺合孔３４にねじ込む。このようにして第（１）番目の曲線取付基板４の基板１上への固定が行われる。このときの図６（ａ）のｄ−ｄ線の断面の状態は、図６（ｄ）に示すとおりである。

次に図６（ｂ）に示すように、第（１）番目の曲線取付基板４の右半分の上面に第▲２▼番目のＢ’タイプの短尺曲線軌道レール３を載せる。このとき第（２）番目の曲線取付基板４の左半分を第▲２▼番目の短尺曲線軌道レール３の下側に位置させておくと、第▲２▼番目の短尺曲線軌道レール３を傷めることなく第（２）番目の曲線取付基板４を取り付けることができる。そして、第▲２▼番目の短尺曲線軌道レール３の左半分の基準面１８を第（１）番目の曲線取付基板４の右半分の曲線軌道レール締結基準面７に押し付けて、上面視で第▲２▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させる。
次に第（２）番目の曲線取付基板４の左半分を第▲２▼番目の短尺曲線軌道レール３の右半分の下面と基板１との間に挿入し、第（２）番目の曲線取付基板４の左端を継ぎ目３０を介して第（１）番目の曲線取付基板４の右端に連結する。そして、第（２）番目の曲線取付基板４の左半分の曲線軌道レール締結基準面７を第▲２▼番目の短尺曲線軌道レール３の右半分の基準面１８に押し付けて、上面視で第▲２▼番目の短尺曲線軌道レール３の基準面１８と第（２）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させる。
そして、第（２）番目の曲線取付基板４の右半分を仮締めして動かないようにする。第▲２▼番目の短尺曲線軌道レール３を第（１）番目及び第（２）番目の曲線取付基板４上から取り外し、結合ボルト３３を第（２）番目の曲線取付基板４の左端から１、３番目の段付挿通孔３２に挿通させ、螺合孔３４にねじ込む。このようにして第（２）番目の曲線取付基板４の左半分の基板１上への固定が行われる。以下、同様に短尺曲線軌道レール３を案内用の治具にして、基板１の上に第（３）番目───第（ｎ）番目の曲線取付基板４を順次に基板１に固定して所望の円弧（半径）の曲線取付基板４の列をつくる。
【００２１】
図６（ｃ）に示すように、第（１）番目の曲線取付基板４の左半分の上に第▲１▼番目のＡ’タイプの短尺曲線軌道レール３を載せる。第▲１▼番目の短尺曲線軌道レール３の内側の基準面１８を第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させ、第▲１▼番目の短尺曲線軌道レール３を仮締めして動かないようにする。取付ボルト２１を第▲１▼番目の短尺曲線軌道レール３の段付挿通孔１９及び曲線取付基板４の挿通孔２２に挿通させ、螺合孔２９にねじ込む。このようにして第▲１▼番目の短尺曲線軌道レール３が第（１）番目の曲線取付基板４の左半分の上面への固定が行われる。
同様にして、第▲２▼番目のＢ’タイプの短尺曲線軌道レール３を第（１）番目の曲線取付基板４の右半分及び第（２）番目の曲線取付基板４の左半分の上面に固定する。そして、第▲３▼番目からｎ−１番目のＢ’タイプの短尺曲線軌道レール３及び第ｎ番目のＡ’タイプの短尺曲線軌道レール３を順次に曲線取付基板４の上面へ固定し、第▲１▼番目から第ｎ番目の短尺曲線軌道レール３の列からなる曲線軌道レール２が得られる。なお、曲線取付基板４を基板１上に載せ仮締めして動かないようにした後に、ドリル等の穿孔器具を曲線取付基板４の段付挿通孔３２、挿通孔２２に挿入し、基板１上に螺合孔３４・２９を形成することも可能である。
【００２２】
このようにして第１実施例の第２組付方法による曲線案内装置の曲線軌道レールの組付が完了する。第２組付方法は、曲線取付基板４の列を作るために、短尺曲線軌道レール３を案内治具にして、上面視で短尺曲線軌道レール３の基準面１８と曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めする。そして、曲線取付基板４の列の上に短尺曲線軌道レール３を並べるときにも、上面視で短尺曲線軌道レール３の基準面１８と曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めする。このように、一端位置決めした短尺曲線軌道レール３を外し、再度同様の位置決めをするので、第１組付方法に較べて、組付に要する手数が多く、組付効率が低い。
なお、短尺曲線軌道レール３と曲線取付基板４の長さ及び孔類の数並びに孔類の間隔は適宜変更することができる。
【００２３】
図７は第２組付方法の変形例を示し、第２組付方法における曲線取付基板４の挿通孔２２を螺合孔２４に変え、基板１の螺合孔２９を省略し、取付ボルト２１を結合ボルト２５に変更し、その余の点は第１組付方法と同様である。つまり、曲線軌道レール２のボルトが取付ボルト２１から結合ボルト２５になったので、螺合孔２９を形成する工数が省略され、組付時間が早くなった。また、基板１に螺合するボルトが第１組付方法の場合の半数になり、基板１への固定力が減少したが、それでも差し支えない用途に用いることになる。
【００２４】
図８（ａ），（ｂ）は第１実施例の曲線案内装置の曲線軌道レールの第３組付方法を示し、第３組付方法（端部継ぎ方式）の特徴は、曲線取付基板４と短尺曲線軌道レール３とを端部から順次に重ね合わせて位置決めし、重なった部分を基板１に固定し、次いでまた重ね合わせ、重なった部分を基板１に固定して、というようにして組付けていくことにある。
基板１上であって曲線取付基板４の段付挿通孔２２の下位置となるべき箇所に、螺合孔２９を形成しておく。図８（ａ），（ｂ）に示すとおり、短尺曲線軌道レール３にはＡタイプとＢタイプの２種の長さのものがあり、Ａタイプの短尺曲線軌道レール３とＢタイプの短尺曲線軌道レール３は、図４に示すもの（第１組付方法で用いたもの）と同一である。曲線取付基板４には８個の挿通孔２２が等間隔で順次に形成されているものを使用する。
【００２５】
図８（ａ）に示すように、先ず第（１）番目の曲線取付基板４を所定の位置におき、第（１）番目の曲線取付基板４の上に第▲１▼番目のＡタイプの短尺曲線軌道レール３を載せる。第▲１▼番目の短尺曲線軌道レール３の内側の基準面１８を第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させる。そして、位置決めした第（１）番目の曲線取付基板４と第▲１▼番目の短尺曲線軌道レール３とを仮締めして動かないようにする。４個（１〜４番）の取付ボルト２１を短尺曲線軌道レール３の左端から順に段付挿通孔１９・挿通孔２２を挿通させ、螺合孔２９にねじ込む。このようにして第▲１▼番目の短尺曲線軌道レール３と第（１）番目の曲線取付基板４の左半分の基板１への固定が行われる。
【００２６】
次に、図８（ｂ）に示すように、第▲２▼番目のＢタイプの短尺曲線軌道レール３を第（１）番目の曲線取付基板４の右半分の上に載せる。図８（ａ）の場合と同様に、第▲２▼番目の短尺曲線軌道レール３の左半分の内側の基準面１８を第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲２▼番目の短尺曲線軌道レール３の左半分の基準面１８と第（１）番目の曲線取付基板４の右半分の曲線軌道レール締結基準面７とが一致し、第▲１▼番目の短尺曲線軌道レール３と第▲２▼番目の短尺曲線軌道レール３が同一半径で連続した円弧となるように位置決めし、その位置に維持させる。このとき、第（２）番目の曲線取付基板４の左半分を第▲２▼番目の短尺曲線軌道レール３の右半分の下側に位置させておくと、第▲２▼番目の短尺曲線軌道レール３を傷めることなく、第（２）番目の曲線取付基板４を取り付けることができる。そして、位置決めした第▲２▼番目の短尺曲線軌道レール３と第（１）番目の曲線取付基板４とを仮締めして動かないようにする。４個（５〜８番）の取付ボルト２１を第▲２▼番目の短尺曲線軌道レール３の左端から順に段付挿通孔１９・挿通孔２２を挿通させ、螺合孔２９にねじ込む。このようにして第▲２▼番目の短尺曲線軌道レール３の左半分と第（１）番目の曲線取付基板４の右半分の基板１への固定が行われる。
同様にして、第（２）番目の曲線取付基板４、第▲３▼番目の短尺曲線軌道レール３という順に組み付け、所定の軌道長さの短尺曲線軌道レール３の列すなわち曲線軌道レール２を組み付けることができる。この第３組付方法は、位置決めと固定の動作を繰り返すので、作業効率が良く、またボルトとしては短尺曲線軌道レール３と曲線取付基板４とを同時に締結する取付ボルト２１のみを用いるので、短尺曲線軌道レール３と曲線取付基板４とが基板１に強固に固定される。なお、短尺曲線軌道レール３と曲線取付基板４とを仮締めして動かないようにした後に、短尺曲線軌道レール３の段付挿通孔１９及び曲線取付基板４の挿通孔２２にドリル等の穿孔器具を挿入し、段付挿通孔１９・挿通孔２２と同一軸線位置で基板１の表面上に所定の深さの螺合孔２９を形成することが可能である。
【００２７】
図８（ａ’），（ｂ’）は第３組付方法の変形例を示し、第３組付方法における曲線取付基板４の偶数番目の挿通孔２２を螺合孔２４に変え、基板１の偶数番目の螺合孔２９を省略し、偶数番目の取付ボルト２１を結合ボルト２５に変更し、その余の点は第３組付方法と同様である。つまり、短尺曲線軌道レール３の偶数番目の取付ボルト２１が結合ボルト２５になったので、螺合孔２９を形成する工数が半分省略され、組付時間が早くなった。また、基板１に螺合するボルトが第１組付方法の場合の半数になり、基板１への固定力が減少したが、それでも差し支えない用途に用いることになる。なお、第３組付方法（変形例を含む。）において、取付ボルト２１の一部を後述第４組付方法の取付ボルト３８に代え、取付ボルト３８に関連する孔類を第４組付方法のように変更することができる。
【００２８】
図９〜図１２は本発明の第２実施例の曲線案内装置を示す。ここに、第２実施例とは、基台１を縦方向に貫通し、基台１の下面に大径部が開口する段付挿通孔３７（大径部が下側）が形成され、基台１と曲線軌道レール２又は曲線取付基板４とが段付挿通孔３７を通るボルトにより締結され、曲線軌道レール２の上面に孔類が開口されず上面全面が平坦であるものをいう。第２実施例では、短尺曲線軌道レール３及び曲線取付基板４の主要な構成は第１実施例の場合と同様であるが、締結・固定用の孔の構成が第１実施例の場合と異なっている。
また、第２実施例でも、第１実施例と同様に、曲線取付基板４の曲線軌道レール締結面６上に短尺曲線軌道レール３が載せられ、短尺曲線軌道レール３の内側の基準面１８が曲線軌道レール締結面基準面７に押し付けられ、短尺曲線軌道レール３の位置決めを行われている。
【００２９】
図９〜図１０には第４組付方法による組付後の状態が示されており、図９は図１１（ｄ）のＩＸ−ＩＸ線の断面を示し、この断面の位置で、短尺曲線軌道レール３には下面から縦方向に高さの略半分に至る未貫通（盲孔）の螺合孔３６が形成され、曲線取付基板４に挿通孔２２が、基台１に段付挿通孔３７がそれぞれ形成されている。基台１の段付挿通孔３７及び曲線取付基板４の挿通孔２２に取付ボルト３８が下側から挿通され、かつ取付ボルト３８が短尺曲線軌道レール３の螺合孔３６にねじ込まれ、短尺曲線軌道レール３と曲線取付基板４とが基板１に締結され、固定されている。曲線軌道レール２（短尺曲線軌道レール３）上に転動体１０を介して摺動体８が摺動自在に案内される。
図１０は図１１（ｄ）のＸ−Ｘ線の断面を示し、この断面の位置で、短尺曲線軌道レール３には前記の螺合孔３６が形成され、曲線取付基板４を縦方向に貫通し、曲線取付基板４の下面に大径部が開口する段付挿通孔５０が形成されている。結合ボルト３９が、段付挿通孔５０を挿通し螺合孔３６にねじ込まれ、短尺曲線軌道レール３と曲線取付基板４とが締結される。
【００３０】
図１１は第２実施例の曲線案内装置の曲線軌道レール２の第４組付方法を示し、この方法は第１組付方法の変形例（図５）を応用したものである。第４組付方法においては、上側の曲線取付基板４と下側の短尺曲線軌道レール３とを順次重ね合わせて締結し、所定の半径の曲線軌道レール２と曲線取付基板４の列とからなる締結レール複合体４１をつくる。そして、この締結レール複合体４１を基台１の上に載せるときに、締結レール複合体４１の上下を逆にして曲線軌道レール２を上側におき、取付ボルト３８を基台１の下側から挿入して曲線軌道レール２等を基台１に固定する。
図１１に示すとおり、曲線取付基板４にはＣタイプとＤタイプの２種の長さのものがあり、Ｃタイプの曲線取付基板４及びＤタイプの曲線取付基板４は、図５に示すもの（第１組付方法の変形例）と同一である。また、短尺曲線軌道レール３には、段付挿通孔５０と対応する位置にのみ螺合孔３６が形成されている。
【００３１】
図１１（ａ）に示すように、先ず第▲１▼番目の短尺曲線軌道レール３の左半分の上に第（１）番目のＣタイプの曲線取付基板４を載せる。第▲１▼番目の短尺曲線軌道レール３の内側の基準面１８に第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させる。次に、第（１）番目の曲線取付基板４の１、３番目の段付挿通孔５０に上方から結合ボルト３９を挿通し、第▲１▼番目の短尺曲線軌道レール３の１、３番目の螺合孔３６に結合ボルト３９を螺合させ、第（１）番目の曲線取付基板４と第▲１▼番目の短尺曲線軌道レール３とを締結する。
【００３２】
次に図１１（ｂ）に示すように、第（２）番目のＤタイプの曲線取付基板４を第▲１▼番目の短尺曲線軌道レール３の右半分の上に載せる。図１１（ａ）の場合と同様に、第▲１▼番目の短尺曲線軌道レール３の右半分の内側の基準面１８に第（２）番目の曲線取付基板４の左半分の曲線軌道レール締結基準面７を押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の右半分の基準面１８と第（２）番目の曲線取付基板４の左半分の曲線軌道レール締結基準面７とが一致し、第（１）番目の曲線取付基板４と第（２）番目の曲線取付基板４が同一半径で連続した円弧となるように位置決めし、その位置に維持させる。次に、第（２）番目の曲線取付基板４の１、３番目の段付挿通孔５０に結合ボルト３９を挿通し、第▲１▼番目の短尺曲線軌道レール３の５、７番目の螺合孔３６に結合ボルト３９を螺合させ、第（２）番目の曲線取付基板４と第▲１▼番目の短尺曲線軌道レール３とを締結する。
【００３３】
同様にして、図１１（ｃ）に示すように、第▲２▼番目の短尺曲線軌道レール３、第（３）番目のＤタイプの曲線取付基板４、第▲３▼番目の短尺曲線軌道レール３、───第（ｎ−１）番目のＤタイプの曲線取付基板４、第ｎ番の短尺曲線軌道レール３、第（ｎ）番目のＣタイプの曲線取付基板４の順に締結する。このように曲線取付基板４と短尺曲線軌道レール３とを順次に締結して、所定の半径の円弧を有する曲線軌道レール２と曲線取付基板４の列との締結レール複合体４１が得られる。前記のとおり、この締結レール複合体４１の上下を逆にし、曲線軌道レール２を上側にして基板１に固定する。
【００３４】
図１１（ｄ）は締結レール複合体４１を基板１に固定した状態が示されている。固定する場合には、基板１上で所定の位置（挿通孔２２の真下となるべき位置）に挿通孔２２と同一数の段付挿通孔３７（大径部が下側）を形成しておく。締結レール複合体４１を基板１の所定の位置に置き、締結レール複合体４１を仮締めして動かないようにする。締結レール複合体４１の下方に相当する位置に、等間隔の段付挿通孔３７が段付挿通孔５０の中間位置の下方に形成されている。段付挿通孔３７にドリル等の穿孔器具を挿入し、挿通孔２２と略同一軸線位置で曲線軌道レール２（短尺曲線軌道レール３）に下側から所定深さ（曲線軌道レール２の高さの約半分）の螺合孔３６を形成する。段付挿通孔３７は取付ボルト３８よりも大径につくり、段付挿通孔３７の軸芯と螺合孔３６の軸芯との間にずれがあっても、組付ができるようにする。螺合孔３６の形成後に切屑を排除し、取付ボルト３８を曲線軌道レール２の左端から段付挿通孔３７及び曲線取付基板４の挿通孔２２を挿通させ、螺合孔３６にねじ込む。このようにして締結レール複合体４１の基板１への固定が行われる。その余の点は、第１組付方法の変形例と同様である。
なお、段付挿通孔３７及び挿通孔２２を所定の位置に精確に形成することができる場合には、すべての螺合孔３６を組付前に形成しておくことができる。このようにすれば、組付現場で螺合孔３６を形成する必要がなく、組付に要する時間を短縮することが可能である。
こうして第２実施例の第４組付方法による曲線案内装置の曲線軌道レールの組付が完了する。第４組付方法により組み付けられた曲線軌道レール２は、上面に孔が存在せず、上面全面が平坦である。
【００３５】
図１１（ｄ）のＩＸ−ＩＸ断面の構成（図９参照）に変えて図１１（ｅ）の構成を採用し、第４組付方法の変形例とする。この変形例では、図１１（ａ）の曲線取付基板４の挿通孔２２を螺合孔２４に変え、結合ボルト４０を段付挿通孔３７に挿通して螺合孔２４にねじ込み、結合ボルト４０によって曲線取付基板４と基板１とを締結する。結合ボルト４０の上方位置に螺合孔３６があってもなくてもよい。その余の点は、第４組付方法と同様である。
【００３６】
図１２は第２実施例・第５組付方法を示し、第５組付方法は図６の第２組付方法を応用したものである。第５組付方法の特徴は、短尺曲線軌道レール３を案内用の治具にして、基板１の上に複数の曲線取付基板４の端部を連結部を介して連結し、順次に曲線取付基板４を基板１に固定して所望の円弧の曲線取付基板４の列をつくる。次に、この曲線取付基板４の列の上に短尺曲線軌道レール３を載せ、基板１の下側から挿入した取付ボルト３８によって短尺曲線軌道レール３を基板１に固定するものである。
図１２に示すとおり、短尺曲線軌道レール３には２種の長さのものがあり、Ａ’’タイプの短尺曲線軌道レール３はＡタイプの短尺曲線軌道レール３に対応する長さであり、Ｂ’’タイプの短尺曲線軌道レール３はＢタイプの短尺曲線軌道レール３に対応する長さであり、共に上面に孔類は開口されていない。
【００３７】
図１２（ａ）及び図１２（ｂ）の説明は、図６（ａ）及び図６（ｂ）の説明と同様であり、図１２（ａ）及び図１２（ｂ）に示す方法により、所定の円弧（半径）の曲線取付基板４の列を基板１に固定する。このとき、挿通孔２２の下位置には既に段付挿通孔３７が形成してある。
図１２（ｃ）に示すように、第（１）番目の曲線取付基板４の左半分の上に第▲１▼番目のＡ’’タイプの短尺曲線軌道レール３を載せる。第▲１▼番目の短尺曲線軌道レール３の内側の基準面１８を第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７に押し付けて、上面視で第▲１▼番目の短尺曲線軌道レール３の基準面１８と第（１）番目の曲線取付基板４の曲線軌道レール締結基準面７とが一致するように位置決めし、その位置に維持させ、第▲１▼番目の短尺曲線軌道レール３を仮締めして動かないようにする。段付挿通孔３７にドリル等の穿孔器具を挿入し、挿通孔２２と略同一軸線位置で第▲１▼番目の短尺曲線軌道レール３に下側から所定深さ（短尺曲線軌道レール３の高さの約半分）の螺合孔３６を形成する。段付挿通孔３７は取付ボルト３８よりも大径につくり、段付挿通孔３７の軸芯と螺合孔３６の軸芯との間にずれがあっても、組付ができるようにする。螺合孔３６形成後に切屑を排除し、取付ボルト３８を左端から段付挿通孔３７及び曲線取付基板４の挿通孔２２を挿通させ、螺合孔３６にねじ込む。このようにして第▲１▼番目の短尺曲線軌道レール３の基板１への固定が行われる。
【００３８】
同様にして、第▲２▼番目のＢ’’タイプの短尺曲線軌道レール３を第（１）番目の曲線取付基板４の右半分及び第（２）番目の曲線取付基板４の左半分の上面に固定する。そして、第▲３▼番目からｎ−１番目のＢ’’タイプの短尺曲線軌道レール３及び第ｎ番目のＡ’’タイプの短尺曲線軌道レール３を順次に曲線取付基板４の上面へ固定し、第▲１▼番目から第ｎ番目の短尺曲線軌道レール３の列からなる曲線軌道レール２が得られる。
なお、段付挿通孔３７及び挿通孔２２を所定の位置に精確に形成することができる場合には、すべての螺合孔３６を組付前に形成しておくことができる。このようにすれば、組付現場で螺合孔３６を形成する必要がなく、組付に要する時間を短縮することが可能である。
【００３９】
曲線軌道レール２の上方に摺動体８が摺動自在に案内されている。摺動体８を駆動するための第１駆動方式と第２駆動方式について、以下に説明する。
第１駆動方式では、図１〜３、図１３に示すように、タイミングベルト４３の歯４４のない平面側を曲線軌道レール２及び曲線取付基板４の外側面で突部５の上面に接合し、歯４４を表面に露出させる。図１３（ｂ）に示すように、摺動体８の上面にテーブル４６を載せ、テーブル４６の段付挿通孔５５（大径部が上側）に連結ボルト４５を挿通させ、連結ボルト４５を摺動体８の螺合孔５６に螺合し、段付挿通孔５５に盲栓５７を配設し、摺動体８にテーブル４６を連結する。テーブル４６の取付孔に回転駆動ユニット５８を配設し、回転駆動ユニット５８の回転軸５３の先端に歯車４７を嵌合し、止めねじ４９をねじ込んで歯車４７の抜け出しを防止する。歯車４７の歯４８をタイミングベルト４３の外面の歯４４と噛み合わせ、モータ５４が回転すると回転力が回転軸５３を介して歯車４７に伝動し、テーブル４６が移動する。図１３（ａ）の上面視で、歯車４７が時計方向に回転するとき、テーブル４６は回転駆動ユニット５８と共にＦ方向に移動し、歯車４７が反時計方向に回転するとき、テーブル４６はＧ方向に移動する。
【００４０】
第２駆動方式では、図１４に示すように、タイミングベルト６０の歯６１のある面を曲線軌道レール２及び曲線取付基板４の外側面で突部５の上面に当接し、タイミングベルト６０の一端を固定し、他端を仮止めする。図１４（ｄ）に示すラック６７が、曲線軌道レール２又は曲線取付基板４の外側面の両端部又はその他の必要な部分又は全面に形成され、ラック６７とタイミングベルト６０の面６１とが噛み合う。こうした噛み合いにより、曲線軌道レール２又は曲線取付基板４とタイミングベルト６０との位置決めが確実となり、固定が強化される。図１３（ｂ）と同様に摺動体の上面にテーブルを載せ、テーブルの段付挿通孔に連結ボルトを挿通させ、連結ボルトを摺動体の螺合孔に螺合し、摺動体にテーブルを連結する。テーブルの取付孔に回転駆動ユニットを配設し、回転駆動ユニットの回転軸６３の先端に歯車６４を嵌合し、止めねじをねじ込んで歯車６４の抜け出しを防止する。図１４（ｂ）に示すように、歯車６４にタイミングベルト６０を巻き掛け、タイミングベルト６０の内面の歯６１と歯車６４の歯６６とを噛み合わせ、タイミングベルト６０の他端を引張りながら固定する。そして、タイミングベルト６０表面の歯車６４の近傍に位置する部分を、２個のテンショナー６２のローラー６５で押圧してタイミングベルト６０に張力を加え、タイミングベルト６０と歯車６４との噛み合いを確実にする。図１４（ａ），（ｂ）の上面視で、歯車６４が時計方向に回転するとき、テーブルは回転駆動ユニットと共にＧ方向に移動し、歯車６４が反時計方向に回転するとき、テーブルはＦ方向に移動する。

【発明の効果】
本発明においては、曲線案内装置において、曲線取付基板には上部に曲線軌道レール締結面が形成され、曲線軌道レール締結面の端部には上方へ突出した突条が形成され、突条の側部に曲線軌道レール締結基準面がそれぞれ形成され、短尺曲線軌道レールの端部を相互に連結することにより所定の軌道長さの曲線軌道レールが構成され、基台と曲線軌道レールとの間に曲線取付基板が配設され、曲線軌道レールの側部と曲線取付基板の曲線軌道レール締結基準面とが当接され、曲線軌道レールと曲線取付基板には締結用の挿通孔又は螺合孔が形成され、曲線取付基板の列の端部が短尺曲線軌道レールの列の端部の連結部と重ならない位置に配置され、曲線軌道レールが取付ボルトにより基台に締結される。従って、曲線取付基板を用いることによって、組付現場において円弧の測定をすることなく、従来と同一の構成の複数の短尺曲線軌道レールを基台上の精確な円弧・レール半径を有する位置に配置して曲線軌道レールとなすことができる。
また、本発明では、曲線取付基板の列の側部又は曲線軌道レールの側部に、歯を外面又は内面に向けたタイミングベルトが配設され、摺動体にテーブルが連結され、テーブルに回転駆動ユニットが配設され、回転駆動ユニットの回転軸に歯車が結合され、前記歯車の歯がタイミングベルトの外面又は内面の歯と噛み合わせられる。従って、摺動体及びテーブルを簡易な機構によって駆動することができる。

[Industrial applications]

[0002]
[Prior art]
As shown in FIG. 15 (a), in the conventional curve guide device, a curved track rail 2 is mounted on a base (base mounting surface) 1 and slides on the curved track rail 2 via a rolling element 10. The moving body 8 is slidably guided.
As shown in FIGS. 15B and 15C, when assembling the curved track rail 2 on the base 1, the pins 11 are planted at intervals on an arc line on the base 1. Then, the short curved track rail 3 is gently placed on the base 1. The reference surface on the inner side of the short curved track rail 3 (the left side in FIGS. 15B and 15C) is brought into contact with these pins 11, and the end of the short curved track rail 3 is connected by a connecting portion (joint portion) 9. The curved track rails 2 having a predetermined track length are formed by approaching each other and leaving a necessary interval. Next, a plurality of horizontal push bolt blocks 12 are placed on the base 1 at positions outside the short curved track rail 3 (the right side in FIGS. 15B and 15C). The tip of the lateral push bolt 13 screwed into the screw hole is brought into contact with the outer side surface (opposite reference surface) of the curved track rail 2. A mounting bolt is inserted into the stepped hole 14 of the curved track rail 2, and the mounting bolt is lightly screwed into a screw hole (a previously formed screw hole) of the base 1, and the curved track rail 2 is temporarily fastened to the base 1. . The horizontal push bolt block 12 is fixed to the base 1, and the horizontal push bolt 13 is screwed so that the tip of the horizontal push bolt 13 is in close contact with the outer reference surface outside the curved track rail 2 on average. There is “play” between the stepped hole 14 and the stepped bolt, and the center of the stepped hole 14 and the center of the stepped bolt can be shifted and screwed together. Using a measuring jig (not shown), a dial gauge is applied to the outer corner of the curved track rail 2 to measure the circularity of the arc. As a result of the measurement, for a portion having extremely poor roundness, the short curved track rail 3 is removed and reinstalled. By repeating such operations, the curved track rail 2 is accurately positioned on the base 1, the mounting bolts are tightened in order from the center to both ends by a torque wrench, and the curved track rail 2 is fixed to the base 1. .
[0003]
By using an NC grinder or the like, a short curved track rail 3 having an accurate rail radius R and roundness is manufactured. Therefore, when only one short curved track rail 3 is used, the short curved track rail 3 may be fixed to the base 1 with mounting bolts without measuring an arc (measurement of roundness). However, since a plurality of short curved track rails 3 are usually used as a curved track rail 2 having a predetermined track length by connecting a plurality of short curved track rails 3, when the curved track rail 2 is mounted on the base 1 as described above, In addition, it is necessary to repeat the measurement of the roundness at the assembly site of the curved track rail 2 to perform positioning, and the assembly requires a lot of time and trouble.

[0010]
As shown in FIG. 4A, the (1) th A-type short curved track rail 3 is first placed on the (1) th curved mounting board 4. The reference surface 18 inside the (1) -th short curved track rail 3 is pressed against the curved track rail fastening reference surface 7 of the (1) -th curved mounting board 4, and the (1) -th short track is viewed from above. The reference surface 18 of the curved track rail 3 and the curved track rail fastening reference surface 7 of the (1) th curved mounting board 4 are positioned so as to coincide with each other, and are maintained at that position. In this case, the use of the C clamp 27 or the like shown in FIG. 4E can simplify this operation, and the use of the C clamp 27 or the like is also performed in other similar operations. Next, the connecting bolt 25 is inserted into the first and third stepped insertion holes 19 of the (1) -th short curved track rail 3, and the first and third screws of the (1) -th curved mounting board 4. A connecting bolt 25 is screwed into the mating hole 24 to fasten the (1) th short curved track rail 3 and the (1) th curved mounting board 4. The connecting bolt 25 has a length such that the tip of the connecting bolt 25 does not protrude from the lower surface of the curved mounting board 4 after fastening. Further, if the stepped insertion hole 19 of the short curved track rail 3 is made slightly larger, even if the axis of the stepped insertion hole 19 and the axis of the screwing hole 24 are slightly displaced due to positioning, the coupling bolt 25 can be moved. It can be screwed into the screw hole 24. These points also apply to other similar fastenings.
[0011]
When the (1) th A-type short curved track rail 3 and the (1) th curved mounting board 4 are fastened, the length of the curved mounting board 4 is the length of the A-type short curved track rail 3. As shown in FIG. 4A, the upper surface of the right half of the curved mounting board 4 is exposed. Then, as shown in FIG. 4 (b), the (2) -th B-type short curved track rail 3 is placed on the right half of the (1) -th curved mounting board 4. As in the case of FIG. 4A, the reference surface 18 inside the left half of the (2) -th short curved track rail 3 is changed to the curved track rail fastening reference surface 7 of the (1) th curved mounting board 4. And the left half reference surface 18 of the (2) -th short curved track rail 3 and the right half curved track rail fastening reference surface 7 of the first curved mounting board 4 match in top view, The (1) -th short curved track rail 3 and the (2) -th short curved track rail 3 are positioned so as to form a continuous arc with the same radius, and are maintained at that position. Next, the connecting bolts 25 are inserted into the first and third stepped through holes 19 of the (2) th short curved track rail 3, and the fifth and seventh screws of the (1) th curved mounting board 4. A connecting bolt 25 is screwed into the mating hole 24 to fasten the (2) -th short curved track rail 3 and the (1) -th curved mounting board 4.

Similarly, as shown in FIG. 4 (c), the (2) th curved mounting board 4, (3) the B-type short curved track rail 3, and the (3) th curved mounting board 4 Ｎ Fasten the (n-1) th B-type short curved track rail 3, the (n) th curved mounting board 4, and the nth A-type short curved track rail 3. In this manner, the short curved track rail 3 and the curved mounting board 4 are sequentially fastened to assemble the fastening rail composite 28 of the curved track rail 2 having a predetermined radius of arc and the row of the curved mounting board 4. Since the fastening between the short curved track rail 3 and the curved mounting board 4 uses two connecting bolts 25 in any combination, the fastening rail complex 28 is formed by the row of the curved track rail 2 and the curved mounting board 4. It is securely fastened, and the shape of the fastening rail complex 28 does not change even in normal handling. The curved rail 2 can be assembled by mounting the fastening rail composite 28 on the substrate 1 and fixing it. However, when a high-precision arc is required, the arc of the fastening rail composite 28 is It is also possible to measure the roundness and make adjustments according to the measurement results.
[0013]
FIG. 4D shows a state in which the fastening rail composite 28 is fixed to the substrate 1. The same number of screw holes 29 as the insertion holes 22 are formed at predetermined positions (positions substantially coincident with the insertion holes 22) on the substrate 1. The fastening rail complex 28 is placed at a predetermined position on the substrate 1, that is, at a position where the insertion hole 22 and the screw hole 29 are substantially coaxial, and the fastening rail complex 28 is temporarily fastened so as not to move. The mounting bolts 21 are inserted through the even-numbered stepped insertion holes 19 from the left end of the curved track rail 2 and the insertion holes 22 of the curved mounting board 4, and screwed into the screw holes 29. Thus, the fastening rail composite 28 is fixed to the substrate 1. As described above, the connecting portions 9 between the short curved track rails 3 and the joints 30 between the curved mounting boards 4 are displaced in the longitudinal direction, and they do not overlap. Further, it is desirable that the tightening force be made substantially constant by using a torque wrench when screwing the connecting bolt 25 and the mounting bolt 21. (These points are the same in other assembling methods.) After the fastening rail complex 28 is temporarily tightened so as not to move, even-numbered stepped through holes from the left end of the curved track rail 2 are used. A drilling tool such as a drill is inserted into the insertion hole 19 of the curved mounting board 19 and the insertion hole 22, and a screwing hole 29 having a predetermined depth is formed on the surface of the board 1 at substantially the same axial position as the stepped insertion hole 19 and the insertion hole 22. It is also possible.
Thus, the assembly of the curved track rail of the curved guide device by the first assembly method of the first embodiment is completed. The stacking method of the first assembling method is broadly divided into two operations, that is, creation of the fastening rail complex 28 and fixing of the fastening rail complex 28 to the substrate 1, and the same kind of work is collectively performed. The work efficiency is extremely high as compared with other assembling methods, and the curved track rail 2 can be assembled in a relatively short time. In addition, the length of the short curved track rail 3 and the curved mounting board 4, the number of holes, and the interval between the holes can be appropriately changed. However, it is desirable that the connecting bolts 25 and the mounting bolts 21 are arranged alternately, and that the fastening between the short curved track rail 3 and the curved mounting board 4 uses two or more connecting bolts 25 in any combination. Further, in the first assembling method, a mounting bolt 38 of a fourth assembling method described later may be adopted instead of the mounting bolt 21, and holes related to the mounting bolt 38 may be changed as in the fourth assembling method. it can.
