【０００１】
【産業上の利用分野】
本発明は、駆動輪に巻掛けされる帯体の進退方向の屈折を規制し進退作動させる帯体の伸長繰出装置に関する。
【０００２】
【従来の技術】
産業用機器又は装置等において直線往復運動を利用し、種々の被作動部材の昇降や押動及び搬送、及びリンク機構を介して円運動をさせることによりシャッターや扉等の開閉作動、並びにハンドリング作動をさせて種々の作業を行わせる往復運動発生装置（進退作動装置）が多用されている。従来の往復運動発生装置は、メカニカル式で大動力を発生させる作動手段として、油圧をシリンダ内に圧送しピストンを押動させる油圧方式の油圧シリンダ装置、或いはこれを空気で行うエアーシリンダ装置がある。またシリンダ内のネジ杆をモータで回動し該ネジ杆に螺合するピストンを直線往復動させる方式の電動シリンダ等が公知である。
【０００３】
【発明が解決しようとする課題】
然し、上記従来構成のシリンダ内に嵌挿されたピストンを伸縮動させる直線往復運動発生装置は、何れのものもピストンの往復動距離に対しそれと同等以上のシリンダ長さを要するため装置が大型化構成になって、設置スペースに制約を受けたり機体重量を増大させる等の欠点がある。そして、前者の油圧シリンダ装置は、油圧ポンプ及び切換操作バルブ並びに油圧タンク、さらにはパイピング等多くの部品からなる駆動手段を必要とするために、複雑且つ大重量でコスト高になる問題があると共に、油の漏出防止管理等の煩雑なメンテナンス作業を要する等多くの問題を有している。
【０００４】
一方電動シリンダ装置は、ネジ杆の回転で螺合するピストンを往復動させるので、ピストンを素早く作動させたり極めて長い往復ストロークを小型な構成で製作することが困難な問題がある。またこれらのピストン部分は高精度に仕上げられて摺動すると共に、これを円滑に作動させる上で充分な潤滑油が欠かせないので、極高低温度域での使用並びに薬品雰囲気や汚泥物中での使用に困難性を伴う等の問題がある。
【０００５】
【課題を解決するための手段】
上記従来の問題点を解消するための本発明による進退作動装置の帯体の繰出装置は、第１に、一対の帯体１，１をその先端部を連結して繰出体５０を介して繰り出すことにより側方への屈折を防止した作動部１ａを進退可能に形成する繰出装置Ａにおいて、上記一対の帯体１，１で形成される作動部１ａの内部に中空部１Ｈを形成し、該中空部１Ｈ内に他の繰出装置Ａ１によって進退作動される帯体１を内装させることを特徴としている。
【０００６】
第２に、上記一対の帯体１，１の対向する側に屈折防止用の規制部材１１を突設し、この規制部材１１を互いに突合又は噛合させることにより、帯体１の進退方向の屈折を規制した伸長状態で進退作動させることを特徴としている。
【０００７】
第３に、上記帯体１の規制部材１１に断面平板状の帯体１を対設して作動部１ａを形成するようにしたことを特徴としている。
【０００８】
第４に、上記作動部１ａを帯部１０の長手方向に突条の規制部材１１を一体的に形成した帯体１と、該突条の規制部材１１を長手方向に嵌入して挟持する凹溝１１Ｍを有する規制部材１１，１１を帯部１０に一体的に形成した帯体１とで形成している。
【０００９】
第５に、上記帯体１の少なくとも一方のものの帯部１０と規制部材１１とをプラスチック材又は合成ゴム材によって一体的に形成してなることを特徴としている。
【００１０】
第６に、作動部１ａの先端に工具類或いはチャック類等の作業部６１を取着したことを特徴としている。
【００１１】
第７に、作動部１ａを繰出装置Ａを回動させることにより回転可能に設けたことを特徴としている。
【００１２】
【発明の実施の形態】
本発明の一構成例を図面に基づき説明する。図１に示すＡは本発明に係わる規制部材１１を有する帯体１の組み合わせによって、作動部１ａを進退可能に形成する進退作動装置としての繰出装置であり、該繰出装置Ａは車輌に常設されるジャッキ又は単独に使用されるジャッキ及びフック等を有する巻き上げ式クレーンの支柱昇降装置、並びにアーム伸縮装置等、従来の油圧及び空圧シリンダ方式の往復運動発生装置で用いられる所或いは他の場所において利用可能であり、その小型軽量化及び取扱い性の向上等を図るようにしている。
【００１３】
図１，図２に示すように上記繰出装置Ａは、単体の筐枠状に形成した機体（ケース）２に規制部材１１を有する一対の帯体１，１を内装し、該帯体１，１を外部或いは内部に設置したモータ３ａ、又はハンドル３ｂを係合させて動力及び手動で駆動可能な入力軸３ｃを有する駆動部３によって、作動部１ａを伸縮（進退）作動するようにしている。尚、上記入力軸３ｃは例えば電動ドライバ或いは電動ドリル等の携帯用駆動機器３ｋを着脱可能に装着して駆動するようにしてもよい。即ち、この繰出装置Ａは、後述する駆動及び停止位置維持可能な位置停止伝動機構を有する伝動機構３０を介し、正逆回転可能に駆動される左右のスプロケット（繰出輪）５０，５０を軸架する繰出部（繰出体）５と、該繰出部５の繰出路５ａ両側に通じ左右の帯体１，１の他側を各別に収納する収納部４，４とから構成している。
【００１４】
上記作動部１ａは左右の繰出輪（駆動輪）５０，５０に各噛合する帯体１，１を図２に示すように構成することにより、該繰出輪５０が正転（実線矢印方向）されるとき、左右一対の帯体１，１を収納部４から上方に向けて同時に繰り出し伸長（進動）させて柱状の作動部１ａを形成し、その頭部或いは中途部で後述する任意な被作動部材Ｗを作動させると共に、繰出輪５０の逆転駆動により帯体１，１を同時に巻き込み、上記作動部１ａを縮動（退動）させてその往復作動及び作動停止を行うことができるようにしている。
【００１５】
また前記繰出輪５０を装架する回転軸５１，５１はケース２に軸支すると共に、該回転軸５１上にウォーム歯車３３を駆動輪５０と一体的に取着し、左右のウォーム歯車３３，３３を噛合駆動させるウォーム３２，３２を、一本の駆動軸３１に固着し、該駆動軸３１を駆動輪５０，５０に沿わせて近接させた状態で正逆回転可能に軸支することにより、駆動軸３１は帯体１を進退作動及び停止維持させる際に、帯体１の位置を繰出輪５０の逆転を防止すると共に、停止位置を的確に維持させることができる位置停止伝動機構Ｐ１を簡潔な構成にしている。
【００１６】
他方、上記駆動軸３１の一側端にもウォーム歯車３５を固着し、該ウォーム歯車３５に入力軸３ｃに固着したウォーム３７を噛合させて駆動することにより、前記位置停止伝動機構Ｐ１に加え同様な停止維持伝動機構Ｐ２を二重に併設し、大幅な減速比を得て軽動力で円滑に作動することができると共に、大幅な減速比を得て強力に作動することができ、また位置停止を確実に行うことができる繰出装置Ａをコンパクトに構成するようにしている。
【００１７】
また上記一対の帯体１，１は、その頭部を板状の連結部材（作動部材）６によって連結すると共に、相対向する帯部１０の対面側の幅方向に突出形成した規制部材１１を一体的に形成している。第１構成例として示す同図の帯体１はプラスチック材又は合成ゴム材で型形成され、帯部１０の内部長手方向にスチールコード又は樹脂糸からなる芯線１２を、在来のベルトの内部に設置されるもの同様の工法によって有しており、規制部材１１の突起状の内部には芯片１３を芯線１２に固定させて設け、ベルト状の帯体１の引っ張り及び圧縮方向の強度の向上と巻取り時の可撓性の向上を図るようにしている。
【００１８】
また、規制部材１１は基部側を巾狭にすると共に頭部側を広巾となし、該基部側と頭部側の側面視形状を同じ円弧状面に形成し、また相隣る規制部材１１と規制部材１１との間には、同形状に形成された対向する帯体１の規制部材１１ががたつきなく密着状に噛み合い齟齬する凹部１１ａを該規制部材１１と共に形成し、規制部材１１の裏面側相当位置帯部１０には台形状の突起歯１５を幅方向に形成している。上記規制部材１１は表面は滑動面を有しやや軟質であっても圧縮方向には弾力性を有しない硬質構造としている。
【００１９】
これにより、各帯体１は左右方向の屈折を相対向する規制部材１１と凹部１１ａが繰出に伴い進退方向に噛み合うことにより規制して、剛性を有する柱状の作動部１ａを形成し、また前後方向の剛性は上記帯体１，１の各規制部材１１が幅方向に接合することにより行い、帯体１の収納された長さ相当距離だけ自由に伸長させることを可能にしている。
【００２０】
このとき、帯体１は各繰出輪５０に巻付角θを有して巻掛け駆動されており、作動部材６に加わる作動力（負荷）、即ち帯体伸長時の押圧力及び縮動時の引張力は帯体１，１を介し、繰出輪５０の巻付角θ内に存る前記突起歯１５と同ピッチに形成している各歯５０ａに分散して受け持たせることにより、左右の繰出輪５０，５０は大きな作動力に対しても充分な耐久性を有し、被作動部材Ｗの作動及び支持を良好に行うと共に、帯体１，１の進退繰り出しを円滑に行うようにしている。
【００２１】
上記帯体１は繰出輪５０の側方に形成される収納部４，４内に屈曲或いは巻取り可能に収納されるものであるが、作動部１ａのストロークが短い場合には、帯体１の繰り出し終端側を繰出輪５０に巻掛けた状態で、該終端側を繰出輪５０に取付け固定させるようにしてもよい。また上記繰出路５ａの下方央部には、山形状に形成したガイド５２を左右の駆動輪５０，５０間に設置することにより、左右の規制部材１１の頂部に接して帯体１の垂れ下がりを防止すると共に、上記ガイド５２で前記帯体１に加えられる負荷を分担し、歯５０ａ及び突起歯１５に過大な負荷をかけることを抑制し高性能な繰出装置Ａを構成している。
【００２２】
以上のように構成された繰出装置Ａは、入力軸３ｃに設置されたモータ３ａを正転及び逆転操作することにより、ウォーム３７及びウォーム歯車３５からなる位置停止伝動機構Ｐ２を介し駆動軸３１を正逆に回動させて、該駆動軸３１に固着されたウォーム３２，３２及びウォーム歯車３３，３３からなる位置停止伝動機構Ｐ１，Ｐ２を介して回動軸５１，５１を正逆に回動させて、これと一体な繰出輪５０，５０を同方向に回転させ、該繰出輪５０，５０に噛合する帯体１，１を同時に進退作動することができる。
【００２３】
このようにして繰り出される帯体１，１は、モータ３ａが正転するときは繰出輪５０，５０が実線矢印方向に回転し、帯体１，１をケース２から繰り出して上昇（伸長）させ、またモータ３ａの逆転により繰り出された帯体１，１を下降（縮動）させて、ケース２に収納するように進退作動をさせる。このとき、可撓性を有する帯部１０によって帯体１，１は繰出輪５０の円弧に沿って繰り出される際に、相隣る規制部材１１間の凹部１１ａを放射方向に拡開させるので、該凹部１１ａの間に対向する帯体１の規制部材１１が順次円滑に入り込み、次いで上方の直線部に至ると対向する規制部材１１，１１は互いに固くがたつきのない状態で安定よく噛合し伸直な作動部１ａを形成する。
【００２４】
従って、この作動部１ａは側方の揺れを防止した剛性を有する柱状部材となって伸縮進退作動をすることができ、作動部材６により又はこれに直接的に連結される被作動部材Ｗを的確に押動或いは往復動することができる。即ち、作動部１ａは帯体１，１の頭部が作動部材６によって互いに連結されていること、及び対となる帯体１が相対向する側に規制部材１１によって屈折を規制されることにより、内向き及び外向き方向（対向方向）への屈折を防止されると共に、相対向する規制部材１１，１１の噛合により作動部１ａの中途で帯体１，１が離間することなく、また側方への屈折を帯体１のリンク接合並びに規制部材１１の広巾な接合によって防止されるので、伸長時における帯体剛性を創出することができる。
【００２５】
また作動部１ａの往復（進退）ストロークは、帯体１の収納長さを任意長さに設定することにより自在に設定することができると共に、その繰り出しは繰出輪５０の回転により行うので、繰出装置Ａを簡潔且つ廉価な構成でコンパクトに纏めて製作することができ、また装置の軽量化を図ることができる。尚、作動部１ａの作動力は繰出装置として用いられる帯体の許容荷重と同等に大きくすることができるものであり、充分な耐久性を有すると共にこれを用いた各種作業装置のコンパクト化を図ることができる。さらに繰出装置Ａの作動は簡単な電気配線だけで所望に作動させることができると共に、スピードコントロールを簡単に行うことができるので廉価な構成で操作性のよい繰出装置にすることができる。
【００２６】
そして、モータ３ａの停止時には、該駆動軸３１に固着されたウォーム３２，３２及び回動軸５１に固着されたウォーム歯車３３，３３からなる位置停止伝動機構Ｐ１，Ｐ２が帯体１，１の進退方向への作動を防止するので、帯体１，１に負荷をかけた状態においても作動部１ａの停止姿勢の維持を的確に行うことができる。また上記繰出装置Ａは適宜な回動機構７で回転可能に支持することにより、作動部１ａを簡単に回動することもでき、作動部１ａを進退作動させながら回動を要する自動装置等に簡単且つ便利に使用することがでる等の特徴を有する。
【００２７】
また上記作動部材６には工具類或いはチャック等の任意な作業装置（作業部）を固定又は駆動可能に装着することができるものであり、作動部１ａの進退方向は繰出装置Ａの向きを変えることによって自在に行うことができる。以上の様な構成により作動部１ａを有する繰出装置Ａは、簡潔な構成で小型化を図りながら負荷に耐えることができる進退運動発生装置として、その実用性を広汎に向上することができる利点がある。
【００２８】
以下に上記繰出装置Ａに直接的に或いは一部構造を変更することにより使用可能な帯体並びに繰出装置の各種構成例及び実施形態について説明する。尚前記構成例のものと構成を同じとする部分については説明を省略する。先ず図３に示す第２構成例としての帯体１は、上記第１構成例のものと同様な噛合を行う規制部材１１をその頭部を半瓢箪状の円形状に形成すると共に、帯部１０の歯付平ベルト型帯部１０の両側にガイド帯１０ａを設け、突起部１５に噛合する繰出輪５０の両側を案内するようにしている。
【００２９】
また図４に示す第３構成例の右方の帯体１１Ｒは上記第２構成例のものと同じ構成にする一方、左方の帯体１Ｌは規制部材１１を分割形成し、分割された規制部材１１の基部側をリンクプレート１６及びリンクピン１６ａで各連結することにより一連の帯体を形成し、該規制部材１１はセラミックス或いはアルミ材等の軽量な部材で形成している。
【００３０】
上記第２，第３の各構成例によれば、規制部材１１の頭部は滑らかな先鋭状であることにより、対向する規制部材１１，１１の噛合が繰出時に干渉することなく円滑に行われるので、規制部材１１の高さを高くして剛性の高い作動部１ａを形成することができる等の利点がある。
【００３１】
次に図５に示す第４構成例について説明する。この帯体１は上記第１構成例のものが歯付平ベルト型であるのに対し帯部１０をＶベルト型にしていると共に、既述のものと同様な作動部１ａの噛合を行う規制部材１１の頭部を円形状に形成し、Ｖプーリ状の繰出輪５０に帯部１０を巻掛けて的確に繰り出すようにしている。尚、この場合の帯部１０のガイド５２はローラ又はベルト等の回転するガイド体で構成し、帯体１を円滑に進退及び停止維持させるとよい。
【００３２】
これによれば、規制部材１１の頭部は滑らかな先細状であることにより、対向する規制部材１１，１１の噛合が円滑に行われること、及び帯体１は繰出輪５０のＶ溝に両側を案内されて作動部１ａの進退を側方への傾倒を防止した状態で良好に行うことができる。また作動部１ａは繰出輪５０との摩擦力によって進退作動されるから、作動部材６部分に過負荷等が加えられた場合等に、繰出輪５０を帯体１に対しスリップさせて逃がすことができる等の利点がある。
【００３３】
次に図６に示す第５構成例について説明する。この帯体１は上記第４構成例のものに対し、円弧状の凹溝５０ｂを有するプーリを繰出輪５０としており、これに巻掛けられる帯体１の帯部１０は半円弧状断面となして、相対向する帯体１，１が噛合した状態では断面円形状の円柱状の作動部１ａを形成するようにしている。この場合には、作動部１ａは円柱状に形成されるので該作動部１ａを狭小な箇所で進退作動させ易く、また在来の油圧ピストンと同様の外観を呈することができる等の特徴を有する。尚その他に上記第４構成例のものと同様な効果も奏するものである。
【００３４】
次に図７に示す第１実施形態について説明する。この第１実施形態は上記第３構成例と同様な帯体１を備えた繰出装置Ａを上段に配置すると共に、該帯体１で形成される作動部１ａの内部にスライド可能に嵌挿される小径な円柱状の作動部１ａを形成する帯体１を備えた繰出装置Ａ１を近接設置している。上記帯体１は規制部材１１の平面視央部に円形又は角状の凹入部を形成し、対向する規制部材１１が接合したとき、進退方向に中空な筒状部（中空部）１Ｈを形成するように構成している。またこの作動部材６には任意な物品を保持可能な受具６０を設けている。
【００３５】
また帯体１Ｄの作動部材６ａには物品を挟持可能なチャク爪状の作業部６１を構成支持し、該作動部材６１は前記帯体１の作動部材６の外周に連結具６２を介して軸芯を中心に回動可能に支持されている。そして、小径な帯体１の作動部１ａ内には前記と同様な中空部１Ｈを形成し、その内部に作業部６１を駆動させるハーネス又は連杆等の作業部材８を挿通させている。尚、上記作業部６１はモータ或いは空圧，油圧等で作動される適宜なアクチェータで駆動するとよく、この場合には遠隔操作機器並びにロボットの構成装置として簡潔な構成で省エネを図り最適化することができる等の利点がある。また図示例では下段の繰出装置Ａ１は帯体１は過負荷逃がし可能とするようにプーリ状の繰出輪５０によって進退作動させると共に、回転機構７によって前記軸芯を中心に正逆回転可能に構成している。尚、この場合ガイド５２は円錐台状に形成するとよい。
【００３６】
この例によれば、異なる形状の帯体１と別の帯体１を組み合わせると共に、繰出方式の異なる繰出装置ＡとＡ１とを各種様々に組み合わせることにより、内部の小径な作動部１ａを的確に繰出支持しながら、これらで形成される作動部１ａ，１ａにおいて求められる各種の作業を簡単且つ自由に遂行することができるという特徴がある。また上記両作動部１ａ，１ａを各別に共同動作させることより、両者間で各種物品（ワークＷ）の挟持搬送或いは仕分け作業等を行わせることもできる。
【００３７】
次に図８に示す第６構成例について説明する。この構成例における左方の帯体１Ｌはベルト状の帯部１０の内方央部に首細の円形頭部断面の規制部材１１Ｌを突条に長手方向に沿って形成すると共に、該規制部材１１Ｌの両側に帯部１０の内面に突起歯１５を連続形成し駆動側の繰出輪５０Ｃに噛み合い駆動されるようにしている。また右方の帯体１Ｒは平面視で、上記規制部材１１Ｌの両側面に接合する凹溝１１Ｍを形成する両側の規制部材１１Ｒ，１１Ｒを突条に設けて、該規制部材１１Ｒの表面に前記突起歯１５に噛合する突起歯１５ａを形成し、帯部１０の背面を中高面のプーリ状の繰出輪（遊動輪）５０Ｕによって転接案内している。
【００３８】
また上記繰出輪５０Ｕと対向する部位には帯体１Ｌと１Ｒとを接合させる繰出輪５０Ｔを設置し作動部１ａを形成させると共に、前記繰出輪５０Ｃは繰出輪５０Ｕと同方向側に設けて、両帯体１Ｌ，１Ｒを共に右方側で収納することによりコンパクト化を図っている。この場合の帯体１Ｌ，１Ｒは規制部材１１Ｌ，１１Ｒも共に可撓性を有する部材で形成しており、帯体１Ｒは巻掛けされた中高面によって同図（Ｂ）に示すように凹溝１１Ｍが拡開された状態において、左方の規制部材１１Ｌがこれに円滑に嵌入したのち、同図（Ｃ）に示すように右方の規制部材１１Ｒ，１１Ｒが規制部材１１Ｌを両側から挟持することにより剛性の高い作動部１ａを形成する。
【００３９】
また両帯体１Ｌ，１Ｒに形成される突起歯１５，１５ａは共に同じ大きさで等ピッチにすると伸直な作動部１ａを形成し得るが、図示例においては帯体１Ｌ側の突起歯１５を大きくすることにより突起歯１５ａと噛合した際に、作動部１ａを右方に向けて屈曲形成させながら目的の方向に簡単な機構で且つ自由に進退作動を行うことができるようにしている。尚、この場合作動部１ａの側面に接して移動を案内するガイド部材２Ｇを適所に設置してもよい。また前記規制部材１１Ｒには所定間隔毎にスリット１Ｓを連続的に切欠状に形成してもよく、この場合には繰り出し及び巻取り時の可撓性を良好にしながら内向きの屈折を良好に防止することができる。さらに同図（Ａ）に点線で示すように左方の帯体１Ｌは帯体１Ｒと対向方向から繰り出すようにしてもよく、この場合にも規制部材１１Ｌには所定間隔毎にスリット１Ｓを連続形成することにより上記と同様な効果を奏するものである。
【００４０】図９に示す第７構成例は帯体１Ｌ，１Ｒに突起歯を設けることなく且つプーリ状の繰出輪５０によって進退作動するようにした例を示す。この場合には帯体１Ｌ，１Ｒを過負荷が生じた場合にスリップさせる過負荷逃がし駆動をすると共に、収納部を機体装置の一側に纏めてコンパクトに配置することができるから、例えば自動車のパワーウインドウの駆動機構等として狭小な場所の使用に最適化することができる等の利点がある。尚、この場合にも必要に応じ既述のスリット１Ｓを形成するとよい。
【００４１】
次に図１０に示す第８構成例について説明する。この構成例における左方の帯体１Ｌは平面視において帯部１０の両側に規制部材１１Ｌを設けて半円弧状のＣ型で、内部に後述の規制部材１１Ｒを挟持して接合する規制溝１１Ｍを形成し、遊動側の凹溝プーリ状の繰出輪５０Ｕに転接させている。また右方の帯体１Ｒは前記第７構成例と平面視同形状の規制部材１１Ｒをチェーン状の帯体１０の各リンクプレート毎に分割して接合するように設け、スプロケット状の繰出輪（駆動輪）５０に巻掛け繰り出すことにより内方への屈折を規制し剛性を有するようにしている。
【００４２】
この構成により同図（Ｃ）に示すように、作動部１ａは帯体１Ｌが繰出部において規制溝１１Ｍが拡開した状態で、その内部に帯体１Ｒの規制部材１１Ｒが円滑に嵌入し既述と同様に両規制部材１１Ｌ，１１Ｒが挟持状に接合し剛性高く形成されるものである。尚、帯体１Ｒの帯部１０はチェーンによるものを図示したが、前述のようにベルト状となし規制部材１１Ｒと一体的に形成してもよい。
【００４３】
次に図１１に示す第２実施形態について説明する。この実施形態における左右の帯体１，１は平面視においてチェーン状の帯部１０に半円弧状のＵ型に形成した規制部材１１，１１をリンクプレート毎に設け、繰出時に両規制部材１１，１１の頭部を接合又は離間させた状態で互いの内向きの屈折を防止することにより、規制部材１１，１１の内部に中空筒部１１Ｈを形成する剛性の高い作動部１ａを構成するようにしている。そして、上記中空筒部１１Ｈ内には巻取り繰出可能なハーネス類或いは例えば流体を送るホース等の挿入物８ａを導入保持可能にしている。尚、図示例において帯部１０はチェーンによるものを示したが規制部材１１と一体的に形成されるベルト状のものであってもよい。
【００４４】次に図１２に示す第９構成例について説明する。同図（Ａ）に示す帯体１Ｌは前記第２実施形態のものと同じであるが、左方の帯体１Ｒはプラスチック又はスチール材で断面平板状の規制部材を有しないテープ状となし、該帯体１Ｒを作動部材６に止めネジ６０Ｎによって取着し作動部１ａを形成するようにしている。またこの図示例では該帯体１Ｒの長手方向に形成した凹穴部１Ｒａに繰出輪（駆動輪）５０の突起歯を噛合させて帯体１と共に作動部１ａを進退作動させている。
【００４５】
これにより作動部１ａは、右方への屈折を帯体１Ｌの各規制部材１１が接合することにより防止され、左方への屈折を帯体１Ｒが引っ張り規制するので、一方の帯体の規制部材を省略した簡単で軽量な構成でありながら、作動部１ａを剛性高く形成することができるものである。また同図（Ｂ）に示すように上記帯体１Ｒは帯体１Ｌの規制部材１１と直交する方向に設けてもよく、この場合には帯体１Ｌ側を駆動すると共に、規制部材１１に縦方向に穿設した凹溝１１Ｍに帯体１１Ｒを繰り出しに伴い嵌入させるようにするとよい。
【００４６】
尚、上記各実施形態に示した対となる帯体は、繰出装置Ａの使用状況に合わせ両方のものを同時に駆動して繰り出すようにしてもよく、また片方の帯体を繰出駆動しながら帯体を追動させるようにしてもよい。さらに両方の帯体を繰出輪（遊動輪）５０で誘導支持した状態で該帯体の側面を別途設置される繰出体によって進退可能に繰り出すようにしてもよい。
【００４７】
また帯体１及び規制部材１１は構成例に示すようにプラスチック材或いは合成ゴム材で一体的に形成することにより、小型及び軽量化を要する作業装置、機器等への設置を最適化することができると共に、帯部と規制部材とをプラスチック型を用いて簡単に製作することができる等の利点があると共に、高温及び超低温域及び薬品雰囲気下、並びに汚泥等汚染環境下で使用される直線往復運動発生装置として耐久性及び信頼性の向上を図ることができるものであるが、図示例の帯体のうち鉄材或いはセラミック材等で製作可能な帯体はこれにより製作することも自由である。

[Industrial application fields]
  The present invention relates to a belt extending and feeding device that restricts refraction in the advancing and retreating direction of a belt wound around a drive wheel and operates to advance and retract.
[0002]
[Prior art]
  In industrial equipment or devices, etc., use linear reciprocating motion to raise and lower, push and transport various actuated members, and to perform circular motion via a link mechanism, as well as opening and closing operations of shutters and doors, and handling operations. A reciprocating motion generating device (advancing / retracting operation device) that performs various operations by performing the above-mentioned is frequently used. The conventional reciprocating motion generating device includes a mechanical hydraulic cylinder device that feeds hydraulic pressure into a cylinder and pushes a piston, or an air cylinder device that performs this with air as an operating means that generates mechanically large power. . Also known is an electric cylinder or the like in which a screw rod in a cylinder is rotated by a motor and a piston screwed into the screw rod is linearly reciprocated.
[0003]
[Problems to be solved by the invention]
  However, any of the linear reciprocating motion generating devices that extend and retract the piston inserted into the cylinder of the above-described conventional configuration requires a cylinder length equal to or greater than the piston reciprocating distance, so that the size of the device is increased. Due to the configuration, there are drawbacks such as restrictions on installation space and an increase in the weight of the aircraft. The former hydraulic cylinder device requires a driving means composed of many parts such as a hydraulic pump, a switching operation valve, a hydraulic tank, and piping, and thus has a problem that it is complicated, heavy and expensive. In addition, there are many problems such as requiring complicated maintenance work such as oil leakage prevention management.
[0004]
  On the other hand, since the electric cylinder device reciprocates the piston that is screwed by the rotation of the screw rod, there is a problem that it is difficult to quickly operate the piston or to manufacture an extremely long reciprocating stroke with a small configuration. Also, these piston parts are finished with high precision and slide, and sufficient lubrication oil is indispensable to operate them smoothly, so use in extremely high and low temperatures and in chemical atmospheres and sludges. There are problems such as difficulty associated with use.

[0012]
DETAILED DESCRIPTION OF THE INVENTION
  One of the present inventionConfiguration exampleWill be described with reference to the drawings. A shown in FIG. 1 is a feeding device as an advancing / retreating device that forms an operating part 1a so as to be able to advance and retreat by a combination of strips 1 having a regulating member 11 according to the present invention. The feeding device A is permanently installed in a vehicle. In a place used in a conventional hydraulic and pneumatic cylinder type reciprocating motion generator or other place, such as a pillar lifting device of a hoisting crane having a jack and a hook used alone or a hook, and an arm telescopic device It can be used, and its size and weight are reduced and handling is improved.
[0013]
  As shown in FIGS. 1 and 2, the feeding device A includes a pair of belt bodies 1 and 1 having a regulating member 11 in a machine body (case) 2 formed in a single casing shape. The operating portion 1a is extended and retracted (retracted) by a drive portion 3 having an input shaft 3c that can be driven by power and manually by engaging a motor 3a installed outside or inside 1 or a handle 3b. . The input shaft 3c may be driven by detachably mounting a portable drive device 3k such as an electric driver or an electric drill. That is, the feeding device A is configured to mount left and right sprockets (feeding wheels) 50 and 50 that are driven to rotate forward and backward through a transmission mechanism 30 having a position stop transmission mechanism capable of maintaining driving and stopping positions, which will be described later. The feeding portion (feeding body) 5 is connected to the feeding path 5a of the feeding portion 5 so as to accommodate the other sides of the left and right belt bodies 1, 1 separately.
[0014]
  The operating portion 1a is configured so that the belts 1 and 1 meshing with the left and right feeding wheels (drive wheels) 50 and 50 are configured as shown in FIG. 2, so that the feeding wheel 50 is rotated forward (in the direction of the solid arrow). In this case, the pair of left and right belt bodies 1 and 1 are simultaneously extended and extended (moved) upward from the storage portion 4 to form a column-shaped operating portion 1a, and an arbitrary covering described later on the head or midway thereof. The operating member W is operated, and the belt bodies 1 and 1 are simultaneously wound by the reverse rotation driving of the feeding wheel 50, so that the operating portion 1a is retracted (retracted) so that the reciprocating operation and the operation stopping thereof can be performed. ing.
[0015]
  The rotating shafts 51 and 51 on which the feeding wheel 50 is mounted are supported on the case 2 and a worm gear 33 is integrally attached to the driving wheel 50 on the rotating shaft 51 so that the left and right worm gears 33, The worms 32 and 32 for meshing driving 33 are fixed to one drive shaft 31 and supported so that the drive shaft 31 can be rotated forward and backward in a state of being close to the drive wheels 50 and 50. The drive shaft 31 is provided with a position stop transmission mechanism P1 capable of preventing the reverse rotation of the feeding wheel 50 and maintaining the stop position accurately when the belt 1 is moved forward and backward and maintained. It has a simple structure.
[0016]
  On the other hand, a worm gear 35 is also fixed to one end of the drive shaft 31, and a worm 37 fixed to the input shaft 3c is engaged with the worm gear 35 and driven to drive the position stop transmission mechanism P1. Double stop maintenance transmission mechanism P2 can be installed to obtain a large reduction ratio and to operate smoothly with light power, and to obtain a large reduction ratio and to operate strongly. The feeding device A that can reliably perform the above is configured in a compact manner.
[0017]
  In addition, the pair of band bodies 1, 1 have their heads connected by a plate-like connecting member (actuating member) 6, and a regulating member 11 that protrudes in the width direction on the opposite side of the opposite band 10. It is formed integrally. FirstConfiguration exampleThe band 1 shown in the figure is formed of a plastic material or a synthetic rubber material, and a core wire 12 made of a steel cord or a resin thread is installed inside a conventional belt in the longitudinal direction of the band portion 10. The core piece 13 is fixed to the core wire 12 inside the protruding shape of the regulating member 11 and the belt-like belt body 1 is improved in strength in the tension and compression directions of the belt-like belt 1 and wound up. The flexibility is improved.
[0018]
  Further, the regulating member 11 has a narrow base portion and a wide head portion, the side view shape of the base side and the head side are formed in the same arcuate surface, and the adjacent regulating members 11 A recess 11 a is formed between the regulating member 11 and the regulating member 11 so that the regulating member 11 of the opposing band 1 formed in the same shape is engaged with the regulating member 11 without rattling. Trapezoidal protrusion teeth 15 are formed in the width direction on the back surface side corresponding position band portion 10. The regulating member 11 has a hard structure that has a sliding surface and is slightly soft but does not have elasticity in the compression direction.
[0019]
  As a result, each band body 1 restricts the refraction in the left-right direction by engaging the constraining member 11 and the concave portion 11a in the advancing and retreating direction with each other to form a rigid columnar actuating portion 1a. The rigidity in the direction is performed by joining the regulating members 11 of the band bodies 1 and 1 in the width direction, and can be freely extended by a distance corresponding to the length in which the band body 1 is stored.
[0020]
  At this time, the band 1 is wound around each feeding wheel 50 with a winding angle θ, and the operating force (load) applied to the operating member 6, that is, the pressing force and the contraction when the band is extended. The tension force of the left and right sides is distributed and received by the teeth 50a formed at the same pitch as the protruding teeth 15 existing within the winding angle θ of the feeding wheel 50 through the belt bodies 1 and 1. The feeding wheels 50 and 50 have sufficient durability against a large operating force, and operate and support the actuated member W well, and smoothly advance and retract the belt bodies 1 and 1. ing.
[0021]
  The band 1 is accommodated in the accommodating portions 4 and 4 formed on the side of the feeding wheel 50 so as to be bent or wound, but when the stroke of the operating portion 1a is short, the band 1 The terminal end side may be attached and fixed to the feeding wheel 50 in a state where the feeding terminal end side is wound around the feeding wheel 50. In addition, a guide 52 formed in a mountain shape is installed between the left and right drive wheels 50 and 50 in the lower central part of the feeding path 5a, so that the belt body 1 hangs down in contact with the tops of the left and right regulating members 11. In addition to preventing the load applied to the band 1 by the guide 52, it is possible to suppress an excessive load from being applied to the teeth 50a and the protruding teeth 15 to constitute a high-performance feeding device A.
[0022]
  The feeding device A configured as described above operates the motor 3a installed on the input shaft 3c to rotate forward and backward, thereby driving the drive shaft 31 via the position stop transmission mechanism P2 including the worm 37 and the worm gear 35. The rotating shafts 51 and 51 are rotated in the forward and reverse directions via the position stop transmission mechanisms P1 and P2 composed of the worms 32 and 32 and the worm gears 33 and 33 fixed to the drive shaft 31. Thus, the feeding wheels 50, 50 integrated therewith can be rotated in the same direction, and the belt bodies 1, 1 meshing with the feeding wheels 50, 50 can be simultaneously advanced and retracted.
[0023]
  When the motor 3a rotates forward, the belts 1, 1 fed out in this way rotate the feeding wheels 50, 50 in the direction indicated by the solid line, and draw the belts 1, 1 out of the case 2 to raise (extend). Further, the belts 1, 1 drawn out by the reverse rotation of the motor 3 a are moved down (contracted) and moved forward and backward so as to be housed in the case 2. At this time, when the strips 1 and 1 are fed out along the arc of the feeding wheel 50 by the flexible strip 10, the concave portions 11a between the adjacent regulating members 11 are expanded in the radial direction. The regulating member 11 of the band 1 that faces between the recesses 11a smoothly enters in succession, and then, when reaching the upper straight part, the facing regulating members 11 and 11 are engaged with each other in a stable state without rattling. A straight actuating part 1a is formed.
[0024]
  Accordingly, the actuating portion 1a can be extended and retracted as a columnar member having rigidity that prevents lateral shaking, and the actuated member W connected to the actuating member 6 or directly to the actuating member 6 can be accurately selected. Can be pushed or reciprocated. That is, the operating portion 1a is configured such that the heads of the strips 1 and 1 are connected to each other by the actuating member 6, and the refraction is regulated by the regulating member 11 on the opposite side of the paired strips 1 Further, refraction in the inward and outward directions (opposing directions) is prevented, and the belt bodies 1 and 1 are not separated in the middle of the operating portion 1a due to the engagement of the opposing regulating members 11 and 11, and on the side. Since the refraction to the direction is prevented by the link joining of the band 1 and the wide joining of the regulating member 11, the band rigidity at the time of expansion can be created.
[0025]
  Further, the reciprocating (advancing / retreating) stroke of the operating portion 1a can be freely set by setting the storage length of the belt body 1 to an arbitrary length, and the feeding is performed by the rotation of the feeding wheel 50. The device A can be manufactured compactly with a simple and inexpensive configuration, and the weight of the device can be reduced. The operating force of the operating portion 1a can be made as large as the allowable load of the belt used as a feeding device, and it has sufficient durability and various working devices using the same can be made compact. be able to. Furthermore, the operation of the feeding device A can be performed as desired with simple electrical wiring, and the speed control can be easily performed, so that the feeding device can be made with a low cost structure and good operability.
[0026]
  When the motor 3a is stopped, the position stop transmission mechanism P1, P2 composed of the worms 32, 32 fixed to the drive shaft 31 and the worm gears 33, 33 fixed to the rotating shaft 51 is provided on the belts 1, 1. Since the operation in the advancing / retreating direction is prevented, the operation unit 1a can be accurately maintained in the stopped posture even when a load is applied to the belts 1 and 1. Further, the feeding device A is supported by a suitable rotation mechanism 7 so as to be rotatable, so that the operating portion 1a can be easily rotated. For example, an automatic device that needs to rotate while moving the operating portion 1a forward and backward. It has features such as easy and convenient use.
[0027]
  Further, an arbitrary working device (working portion) such as tools or chucks can be mounted on the actuating member 6 so as to be fixed or drivable, and the advancing / retreating direction of the actuating portion 1a changes the direction of the feeding device A. This can be done freely. The feeding device A having the operation part 1a having the above-described configuration has an advantage that the practicality can be widely improved as a forward / backward motion generating device capable of withstanding a load while being downsized with a simple configuration. is there.
[0028]
  Various types of strips and feeding devices that can be used directly or by changing the structure of the feeding device A below.Configuration examples andEmbodiments will be described. The aboveConfiguration exampleThe description of the parts having the same configuration as those of FIG. First, the second shown in FIG.Configuration exampleThe band 1 as the firstConfiguration exampleAnd a guide band 10a is provided on both sides of the toothed flat belt type band part 10 of the band part 10, and a protrusion part is formed. 15, both sides of the feeding wheel 50 meshing with 15 are guided.
[0029]
  The third shown in FIG.Configuration example11R on the right side of theConfiguration exampleThe left band 1L is formed by dividing the restriction member 11 and connecting the base side of the divided restriction member 11 with the link plate 16 and the link pin 16a. The regulating member 11 is formed of a lightweight member such as ceramics or aluminum material.
[0030]
  Each of the second and thirdConfiguration exampleAccording to the above, since the head of the regulating member 11 is smooth and sharp, the meshing of the opposing regulating members 11 and 11 is smoothly performed without interfering at the time of feeding, so that the height of the regulating member 11 is increased. Thus, there is an advantage that the operation portion 1a having high rigidity can be formed.
[0031]
  Next, as shown in FIG.Configuration exampleWill be described. This belt 1 is the firstConfiguration exampleThe belt portion is a V-belt type while the belt portion is a toothed flat belt type, and the head portion of the regulating member 11 that engages the operating portion 1a similar to the above-described one is formed in a circular shape. Then, the belt portion 10 is wound around the V pulley-shaped feeding wheel 50 so as to be fed out accurately. In this case, it is preferable that the guide 52 of the belt portion 10 is constituted by a rotating guide body such as a roller or a belt so that the belt body 1 can be smoothly advanced and retracted and stopped.
[0032]
  According to this, since the head of the regulating member 11 has a smooth tapered shape, the opposing regulating members 11, 11 are smoothly meshed, and the belt 1 is disposed on both sides of the V groove of the feeding wheel 50. Thus, the operation part 1a can be advanced and retracted well in a state in which tilting to the side is prevented. Further, since the actuating portion 1a is advanced and retracted by the frictional force with the feeding wheel 50, the feeding wheel 50 can be slipped to the belt body 1 and escaped when an overload is applied to the actuating member 6 portion. There are advantages such as being able to.
[0033]
  Next, as shown in FIG.Configuration exampleWill be described. This belt 1 is the fourth oneConfiguration exampleA belt having a circular arc-shaped groove 50b is used as the feeding wheel 50, and the belt portion 10 of the belt body 1 wound around the pulley has a semicircular arc-shaped cross section. In the engaged state, a cylindrical actuating portion 1a having a circular cross section is formed. In this case, since the operation part 1a is formed in a columnar shape, the operation part 1a can be easily moved forward and backward in a narrow place, and can have the same appearance as a conventional hydraulic piston. . In addition to the above,Configuration exampleThe same effect as that of No. is also exhibited.
[0034]
  Next, as shown in FIG.FirstEmbodiments will be described. thisFirstEmbodiment is the thirdConfiguration exampleThe feeding device A having the same belt body 1 is arranged in the upper stage, and a small-diameter columnar operating portion 1a is formed that is slidably inserted into the operating portion 1a formed by the belt body 1. The feeding device A1 provided with the band 1 is installed in proximity. The band 1 forms a circular or square recess in the central portion of the regulating member 11 in plan view, and when the opposing regulating member 11 is joined, it forms a hollow cylindrical portion (hollow portion) 1H in the advancing and retracting direction. It is configured to do. Further, the operating member 6 is provided with a receiver 60 capable of holding an arbitrary article.
[0035]
  The operating member 6a of the band 1D is configured to support a chuck claw-shaped working portion 61 that can hold an article, and the operating member 61 is connected to the outer periphery of the operating member 6 of the band 1 via a connecting tool 62. It is supported so as to be rotatable around the core. And the hollow part 1H similar to the above is formed in the action | operation part 1a of the small diameter belt | band | zone body 1, The work member 8, such as a harness which drives the work part 61, or a linkage, is penetrated in the inside. The working unit 61 may be driven by a motor or an appropriate actuator that is operated by pneumatic pressure, hydraulic pressure, etc. In this case, the remote control device and the robot component device should be optimized with a simple configuration for energy saving. There are advantages such as being able to. In the illustrated example, the lower-stage feeding device A1 is configured to be moved forward and backward by a pulley-like feeding wheel 50 so that the belt 1 can be overloaded, and to be rotated forward and backward about the shaft core by a rotating mechanism 7. doing. In this case, the guide 52 is preferably formed in a truncated cone shape.
[0036]
  According to this example, while combining the belt body 1 having a different shape and another belt body 1 and various combinations of the feeding devices A and A1 having different feeding systems, the internal small-diameter operating portion 1a can be accurately obtained. There is a feature that various operations required in the operating portions 1a and 1a formed by these can be easily and freely performed while being extended and supported. In addition, by operating both the operating parts 1a and 1a separately, it is possible to hold and convey various articles (work W) between them or to perform sorting work.
[0037]
  Next, as shown in FIG.Sixth configuration exampleWill be described. thisConfiguration exampleThe left belt body 1L is formed with a narrow circular head cross-section restricting member 11L along the longitudinal direction at the inner central part of the belt-like belt portion 10, and on both sides of the restricting member 11L. Further, the protruding teeth 15 are continuously formed on the inner surface of the belt portion 10 so as to be engaged with and driven by the driving-side feeding wheel 50C. Further, the right belt body 1R is provided with protrusions on both sides of the restricting members 11R and 11R that form concave grooves 11M that are joined to both side surfaces of the restricting member 11L in plan view. Protruding teeth 15a meshing with the protruding teeth 15 are formed, and the back surface of the belt portion 10 is guided by rolling contact with a pulley-like feeding wheel (idling wheel) 50U having a medium-high surface.
[0038]
  In addition, a feeding wheel 50T for joining the belt bodies 1L and 1R is installed at a portion facing the feeding wheel 50U to form an operating portion 1a, and the feeding wheel 50C is provided on the same direction side as the feeding wheel 50U. The two bands 1L and 1R are both housed on the right side to achieve compactness. In this case, the band bodies 1L and 1R are formed of flexible members as the regulating members 11L and 11R, and the band body 1R is a concave groove as shown in FIG. In a state where 11M is expanded, after the left regulating member 11L is smoothly inserted into the left regulating member 11L, the right regulating members 11R and 11R sandwich the regulating member 11L from both sides as shown in FIG. Thereby, the highly rigid operation part 1a is formed.
[0039]
  Further, if the projecting teeth 15 and 15a formed on both the band bodies 1L and 1R are both the same size and have the same pitch, it is possible to form the straight operating portion 1a. When the protrusions 15a are engaged with each other, the operating portion 1a is bent toward the right, and can be freely advanced and retracted in a desired direction with a simple mechanism. In this case, a guide member 2G that contacts the side surface of the operating portion 1a and guides the movement may be installed at an appropriate position. In addition, slits 1S may be continuously formed in the regulating member 11R at predetermined intervals, and in this case, inward refraction is improved while flexibility during feeding and winding is improved. Can be prevented. Further, as shown by a dotted line in FIG. 5A, the left band 1L may be extended from the direction opposite to the band 1R. In this case, the restriction member 11L is continuously provided with slits 1S at predetermined intervals. By forming this, the same effects as described above can be obtained.
As shown in FIG.Seventh configuration exampleShows an example in which the belts 1L and 1R are not provided with projection teeth and are moved forward and backward by a pulley-like feeding wheel 50. In this case, it is possible to drive the belt 1L, 1R to be overloaded so that it slips when an overload occurs, and the storage unit can be compactly arranged on one side of the airframe device. There is an advantage that the power window driving mechanism can be optimized for use in a narrow space. In this case, the above-described slit 1S may be formed as necessary.
[0041]
  Next, as shown in FIG.Eighth configuration exampleWill be described. thisConfiguration exampleThe left belt body 1L is a semicircular arc-shaped C-shaped member provided with restricting members 11L on both sides of the belt portion 10 in a plan view, and a restricting groove 11M for sandwiching and joining a later-described restricting member 11R is formed inside. The rolling-side grooved pulley-shaped feeding wheel 50U is in rolling contact. The right belt 1R isSeventh configuration exampleAnd a regulating member 11R having the same shape in plan view is provided so as to be divided and joined for each link plate of the chain-like belt 10, and wound inwardly by being wound around a sprocket-like feeding wheel (driving wheel) 50. The refraction is controlled to have rigidity.
[0042]
  With this configuration, as shown in FIG. 5C, the operating portion 1a has the regulation member 11R of the strip 1R smoothly inserted into the operating portion 1a in a state where the regulation groove 11M is expanded in the strip 1L. In the same manner as described above, both the regulating members 11L and 11R are joined in a sandwiched manner and formed with high rigidity. Although the belt portion 10 of the belt body 1R is illustrated as a chain, it may be formed integrally with the belt-like and belt-less regulating member 11R as described above.
[0043]
  Next, as shown in FIG.Second embodimentWill be described. The left and right belt bodies 1 and 1 in this embodiment are provided with restriction members 11 and 11 formed in a semicircular arc U shape on a chain-like belt portion 10 in a plan view for each link plate, In the state where the heads of 11 are joined or separated from each other, inward refraction is prevented, thereby forming the highly rigid operating part 1a that forms the hollow cylindrical part 11H inside the regulating members 11, 11. ing. In the hollow cylinder portion 11H, an insert 8a such as a harness that can be wound and fed or a hose that sends fluid, for example, can be introduced and held. In the illustrated example, the band portion 10 is shown as a chain, but may be a belt-like one formed integrally with the regulating member 11.
Next, as shown in FIG.Ninth configuration exampleWill be described. The band 1L shown in FIG.SecondAlthough the same as the embodiment, the left band 1R is made of a plastic or steel material and does not have a flat plate-shaped regulating member, and the band 1R is attached to the operating member 6 by a set screw 60N. The wearing operation part 1a is formed. Further, in this illustrated example, the protruding portion of the feeding wheel (driving wheel) 50 is engaged with a recessed hole portion 1Ra formed in the longitudinal direction of the belt body 1R, so that the operating portion 1a is advanced and retracted together with the belt body 1.
[0045]
  Thus, the operating portion 1a is prevented from refraction in the right direction by joining the regulating members 11 of the band 1L, and the band 1R pulls and regulates refraction in the left direction. The operating portion 1a can be formed with high rigidity while having a simple and lightweight configuration in which members are omitted. Further, as shown in FIG. 5B, the band 1R may be provided in a direction orthogonal to the regulating member 11 of the band 1L. In this case, the band 1L side is driven and the regulating member 11 is vertically The belt body 11R may be fitted into the recessed groove 11M drilled in the direction as it is extended.
[0046]
  The pair of belts shown in each of the above embodiments may be driven and fed simultaneously in accordance with the usage status of the feeding device A, and the belts may be fed while driving one of the belts. You may make it follow a body. Furthermore, the side surfaces of the belt body may be fed out by a separately installed feeding body in a state where both belt bodies are guided and supported by the feeding wheel (idling wheel) 50.
[0047]
  The band 1 and the regulating member 11 areConfiguration exampleAs shown in the figure, by integrally forming with plastic material or synthetic rubber material, it is possible to optimize the installation on working devices, equipment, etc. that require miniaturization and weight reduction, and the band and the regulating member are made of plastic. It has the advantage that it can be easily manufactured using a mold, and has improved durability and reliability as a linear reciprocating motion generator used in high-temperature and ultra-low-temperature regions and chemical atmospheres, and in polluted environments such as sludge. However, it is also possible to manufacture a band that can be manufactured from an iron material, a ceramic material, or the like in the illustrated band.
