Description

【0001】
【発明の属する技術分野】
本発明は、主として粘性の高い液体中に含まれた泡を除去する脱泡装置に関するものである。
【0002】
【従来の技術】
従来の脱泡装置は、図6に示すように、筺体1の内部に、水平方向のベース2を設け、このベース2のほぼ中央に主軸3を縦方向に設けて主軸3の下端をゴム塊4を介して筺体1の底部で支持し、ベース2の外周縁と筺体1との間に細いワイヤーロープ5を複数箇所斜めに張設し、主軸3を挟んで自転用モータ6と公転用モータ7をベース2の左右に取り付け、各モータ6,7の出力軸をベース2の上方に突出させ、上記主軸3の上部に横長な回転フレーム8を固定し、回転フレーム8の一方の端部に副軸9を、上部を主軸3側に傾斜した状態で設け、この副軸9の上部に容器ホルダ10を固定し、主軸3を挟んだ回転フレーム8の他方の端部にカウンタバランスウエイト11を半径方向に移動可能な状態で設けるとともに、カウンタバランスウエイト11の下方にアイドル軸12を縦方向に設けて回転フレーム8を貫通させ、回転フレーム8の上方に突出したアイドル軸12の上端に上アイドルプーリ13を固定し、この上アイドルプーリ13と容器ホルダ10の外周面に形成したホルダプーリとの間に無端ベルト14を掛け渡すとともに該無端ベルト14の途中を回転フレーム8の回転中心に配置した方向転換ローラ15に掛け、回転フレーム8の下方に突出したアイドル軸12の下端に下アイドルプーリ16を固定し、主軸3にベアリングを介して嵌装した自転用プーリ17と上記下アイドルプーリ16との間に無端ベルト18を掛け渡し、主軸3の自転用プーリ17と自転用モータ7のプーリとの間に無端ベルト19を掛け渡し、主軸3に固定した公転用プーリ20と公転用モータ6のプーリとの間に無端ベルト21を掛け渡している。
【0003】
この様な構成からなる脱泡装置においては、公転用モータ6を作動すると、主軸3が回転するとともに回転フレーム8が回転し、この回転フレーム8の回転により容器ホルダ10にセットした容器が主軸3を中心とする円周上を回転、即ち公転する。そして、自転用モータ7を励磁すると、無端ベルト19、自転用プーリ17、無端ベルト18、両アイドルプーリ12,16、及び無端ベルト14の作用により容器ホルダ9に回転力が与えられ、これにより容器が副軸9を中心にして回転、即ち自転する。
カウンタバランスウエイト11を調整しても、回転フレーム8を回転し始めた低速回転時ではバランスが採れないので、回転フレーム8や主軸3等が揺動し、この揺動を前記ゴム塊4の弾性力とワイヤーロープ5の張力とで受け、これにより装置全体が大きく振動することを防止している。なお、回転フレーム8の回転数が所定の回転数に達すると、カウンタバランスウエイト11によるバランス採りとジャイロ効果とによって主軸3の方向が垂直方向に安定する。
【0004】
【発明が解決しようとする課題】
しかしながら、主軸の下端側に介在させたゴム塊により主軸やベースを弾性的に支持しつつ、ベースの外周縁に斜めに張設したワイヤーロープの張力により主軸を揺動可能に支持する構成では、主軸を垂直方向に起立させるための付勢力に複数本のワイヤーロープの張力を利用しているので、ワイヤーロープが経年変化等によって伸びて緩むことがあり、ベースに対する引っ張り力のバランスが崩れることもある。
【0005】
この様に、ワイヤーロープの張力を利用した揺動支持構造では、ワイヤーロープの張力が不足した場合や各ワイヤーロープの張力のバランスが崩れた場合(不揃いになった場合)に、ベースの揺れが却って増大される不都合が生じ易い。
また、複数本のワイヤーロープの張力を長年に亘ってバランスさせることは困難であり、メンテナンスが面倒である。
【0006】
本発明は上記した事情に鑑み提案されたものであり、その目的は、回転フレームや主軸などの回転部分を揺動可能な状態で支持するばかりでなく、主軸を垂直方向に早期に安定させることができる脱泡装置を提供しようとするものである。
【0007】
【課題を解決するための手段】
本発明は上記目的を達成するために提案されたもので、請求項1に記載のものは、モータの出力軸に接続された縦方向の主軸の上部に固定され、主軸を中心にして回転する回転フレームと、
回転フレームに、主軸を中心とする回転中心から外れた位置に配置され、上部を主軸側に傾斜した状態で回転自在に取り付けられた副軸と、
この副軸に取り付けられた容器ホルダと、
を備え、主軸の回転により回転フレームを回転して容器内の処理液の脱泡処理を行なう脱泡装置において、
上記回転フレーム及び主軸を含む回転部分を揺動可能な状態で支持する揺動支持機構を設け、
該揺動支持機構は、上記主軸の軸線上に設けられて主軸を介して少なくとも回転部分の重さを受けるとともに、中心側から外周縁側に向かって次第に厚みを減少させた鍔部を外周面に有する縦方向の支持部材と、上記鍔部の上面と下面にそれぞれ当接した弾性板材と、両弾性板材を鍔部の上面と下面に挟み付けて押圧した状態で保持するホルダと、からなり、
弾性板材の弾性力を、主軸を垂直方向に起立させる付勢力としたことを特徴とする脱泡装置である。
【0008】
請求項2に記載のものは、請求項1の構成に加えて、前記揺動支持機構を水平方向のベースに設け、このベースから上方に突出した主軸の下部を支持部材により支持し、ベースよりも下方に配置したモータを支持部材の下部により支持し、このモータの重さを、主軸を垂直方向に起立させる付勢力として付加したことを特徴とする脱泡装置である。
【0009】
請求項3に記載のものは、前記鍔部が、中心を支持部材の中心に合わせた同心円の円盤状であることを特徴とする請求項1または2に記載の脱泡装置である。
【0011】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図1は脱泡装置30の第1実施形態の構成を示す断面図であり、図2はその要部を示す断面図である。
【0012】
脱泡装置30は、筺体31の上に処理室32を重ねて設け、筺体31の天井面と処理室32の床面とにより水平方向に延在するベース33を構成し、このベース33のほぼ中央に開設した貫通孔内に一部を挿入した状態で揺動支持機構34を設け、この揺動支持機構34により下部を支えた状態で主軸35を縦方向に設け、主軸35の上端に回転フレーム36を固定し、回転フレーム36には上部に容器ホルダ37を取り付ける副軸39を上部が主軸35側に傾斜した状態で設け、回転フレーム36の近くの主軸35の外側にベアリングを介して主プーリ40を主軸35とは独立して回転可能な状態で設け、主プーリ40の回転方向を制御する一方向クラッチ41をベース33上の一側に設け、筺体31の内部に設けたモータ42の出力軸を主軸35の下端にカップリングを介して接続してある。
【0013】
揺動支持機構34は、主軸35や回転フレーム36などの回転部分を揺動可能な状態で支持する機構であり、外周面に鍔部43を有し内部にベアリングを有する支持部材としての軸受本体44と、鍔部43の上面と下面にそれぞれ当接した弾性板材としての上ゴムリング板45a並びに下ゴムリング板45bと、上ゴムリング板45aと下ゴムリング板45bを鍔部43の上面と下面に挟み付けて押圧した状態で保持するホルダ46とからなる。
【0014】
ホルダ46は、上ゴムリング板45aを上方から押圧する金属製の押圧部材47と、ベース33上に固定されて押圧部材47を取り付ける基部49などからなり、下ゴムリング板45bを載置するベース33もその一部を構成している。
【0015】
上記鍔部43は、中心側(基端側)から外周縁側に向かって次第に厚みを減少させた円盤状であり、軸受本体44の筒状部分の上下長さのほぼ中央に配設される。
【0016】
この鍔部43を挟み付けるゴムリング板45は、無負荷状態(外力を加えない自然状態)では均一な厚みの弾性ゴム製板材である。したがって、下ゴムリング板45bと上ゴムリング板45aとの間に鍔部43を挟んで上方から押圧部材47により押圧すると、両ゴムリング板45は、鍔部43の肉厚な部分に当接する部分が強く圧縮され、肉薄な部分に当接する部分は弱く圧縮されることになる。換言すると、図4(a)に示すように、鍔部43の軸受本体44に近い部分(中心側)ほど強い力で挟持されており、外周縁側に向かうにしたがって挟持力が次第に弱く設定されている。
【0017】
この様に、ゴムリング板45に弾性力により外周縁側から中心側に近付くにしたがって次第に強い力で鍔部43を挟み付けていると、主軸35の揺動で軸受本体44が揺動した場合、軸受本体44と鍔部43との交叉部分を中心にして揺動するが、鍔部43が軸受本体44と一体になって揺動した場合に、鍔部43がゴムリング板45を圧縮する力(倒れようとする力、倒力)は、梃子の原理により、中心からの距離に応じて変化する。すなわち、図4(b)に示すように、鍔部43の外周縁側から中心側(軸受本体44側)に近付くに連れて倒れようとする力が次第に増大された大きな力になってゴムリング板45を圧縮し、鍔部43の中心近傍が最も強い力でゴムリング板45を圧縮する。
【0018】
一方、ゴムリング板45について観察すると、鍔部43の外周縁から中心側に近付くにつれて強い力で鍔部43を挟み付けている(押し戻している)。したがって、鍔部43の各部位における倒力の強弱の傾斜に応じた押し戻し力が鍔部43に作用することになり、鍔部43の各部位における倒力に応じた力で鍔部43を初期位置に押し戻すことができ、これにより軸受本体44が揺動しても、この揺動は速やかに収束する。そして、鍔部43は円盤状であり、ゴムリング板45は円盤状鍔部43の上下面を全周面に亘って挟み付けている。このため、主軸35がいずれの方向に倒れても、上下のゴムリング板45の弾性力が鍔部43に押し戻し付勢力として安定して作用し、これにより初期の垂直方向に向けて速やかに起立する。
【0019】
ここで、鍔部を均一な厚みにした場合と比較すると、均一な厚みの鍔部の上下面をゴムリング板により挟み付けると、各部位において同じ強さで挟持していることになる。この状態で軸受本体44が揺動して鍔部がゴムリング板を押圧すると、鍔部の外周縁の変位量(移動長さ)が大きいので、その長さ分だけゴムリング板が圧縮され、この圧縮に応じた力(復元力)で押し戻される。一方、鍔部の外周縁よりも中心側の部位においては変位量が外周縁よりも小さいので、この部分においてゴムリング板によって押し戻される力(復元力)は弱く、軸受本体44近傍においては変位量が極く僅かなので実質的な復元力は期待できない。この様に、鍔部の部位に拘らず同じ力で挟持していたのでは、総復元力が前記本実施形態よりも小さく、主軸が揺動した場合における復元力が弱い。したがって、これに比較して本実施形態の方が、主軸35を垂直方向に速やかに起立させて早期に安定した回転にすることができる。
【0020】
なお、本実施形態においては、ベース33と下ゴムリング板45bとの間、および下ゴムリング板45bと鍔部43との間に回り止めピン50を差し込んで、これらの部材が不用意に周方向に回動することを防止している。
【0021】
また、本実施形態では、軸受本体44の下端面にモータ取付ベース51をボルトで固定し、このモータ取付ベース51の下面にモータ42を固定する。したがって、モータ42の自重は、筺体31に作用することなく軸受本体44に作用し、この自重がゴムリング板45による付勢力(復元力)に付加されて、この総力が主軸35の揺動収束力、振動防止力として作用する。したがって、上下のゴムリング板45だけで押し戻し付勢するよりも強い力で主軸35を垂直方向に起立させることができる。
【0022】
次に、回転フレーム36について説明する。
この回転フレーム36は、正面からみて倒横長台形、上方から見て長方形のアルミニウム製枠体であり、下面部分の中央(即ち、回転フレーム36の中心)を主軸35の上端フランジ部にボルトで固定し、約45°傾斜した両端の傾斜面にそれぞれ副軸用軸受52を設け、傾斜面近傍の下面部分に方向変換ローラ53を回転自在に設ける。なお、方向変換ローラ53は、軸方向を回転フレーム36の幅方向に向けて設け、後述する主プーリ40のベルト溝の上下寸法差に応じて、それぞれ上下差を設けて設ける。
【0023】
副軸用軸受52は、回転フレーム36と一体成型した筒状体の下端開口を蓋で閉じ、内部にベアリングを上下に設け、両ベアリングにより副軸39を回転自在に支持するものである。この副軸用軸受52により副軸39を回転自在に設けると、両副軸39は、回転フレーム36に、主軸35を中心とする回転中心から同じ距離だけ外れた位置、即ち主軸35を中心とする同心円上の周方向に180°の等間隔で配置され、上部を主軸35側に45°傾斜した状態で回転自在に取り付けられることになる。そして、各副軸39の回転フレーム36の内側に突出した上端に容器ホルダ37を固定する。
【0024】
容器ホルダ37は、処理する液体を入れる容器54を支える部材であり、本実施形態では、容器54を収納する筒状体の上端に、爪片55を3箇所同じ間隔で上方に突設してある。したがって、この容器ホルダ37内に容器54を収納すると、爪片55が容器54の係合溝内に係合し、副軸39の回転により容器ホルダ37内の容器54を回転することができる。
【0025】
また、副軸用軸受52の下端を構成する蓋から突出した副軸39の下端は副プーリ56を固定し、この副プーリ56と主軸35に設けた主プーリ40との間に断面が円形の無端ベルト57を、途中を前記方向変換ローラ53の下に通した状態で掛け渡す。
【0026】
主プーリ40は、上下2つのベアリングにより主軸35に対して独立して回転可能な状態で主軸35の上部に同軸上に取り付けられており、外周面には3本のベルト溝が形成されている。3本のベルト溝の内、上方の2本は副プーリ56に掛けた無端ベルト57を掛ける溝であり、断面が略半円形であり、これらのベルト溝から少し離れた下方に形成してある1本は一方向クラッチ41との接続用であり、段付き無端ベルト59の段に応じた凹凸が形成してある。したがって、図2に示すように、上方のベルト溝に掛けた無端ベルト57は、高い方の方向変換ローラ53側の副プーリ56に掛け渡し、その下に位置するベルト溝に掛けた無端ベルト57は、低い方の方向変換ローラ53側の副プーリ56に掛け渡し、一番低い位置のベルト溝に掛けた段付き無端ベルト59は一方向クラッチ41のプーリに掛け渡す。
【0027】
一方向クラッチ41は、主プーリ40の回転方向を、一方向は禁止して他方向は許容する機構である。そして、この一方向クラッチ41の軸に取り付けたプーリと前記主プーリ40との間に段付き無端ベルト59を掛け渡す。
【0028】
したがって、主プーリ40は、主軸35から回転力を受けた場合、例えば時計方向の正回転方向の力を受けたのであれば一方向クラッチ41に許容されて時計方向に主軸35と共に回転(共回り)することができる。主プーリ40が主軸35と共に同じ方向に共回りすると、無端ベルト57により接続された主プーリ40と副プーリ56との間に位相の差が発生しないので、両プーリに偶力が発生することもなく、無端ベルト57の移動(回転力の伝達)が行われず、副軸39は回転しない。このため、副軸39に取り付けた容器ホルダ37も副軸39を中心として回転(自転)することはなく、容器54は、回転フレーム36の主軸35を中心とする回転、即ち公転するだけである。
【0029】
換言すると、主軸35を正方向に回転した場合、回転フレーム36が主軸35を中心にして回転して、これにより容器54が主軸35を中心に公転するが、主プーリ40の共回りによって副軸39は回転しないので、容器54は自転しない。
【0030】
一方、主軸35から反時計方向の回転力を受けた場合、主プーリ40は、段付き無端ベルト59を介して一方向クラッチ41の作用により逆回転が禁止された状態であり、このため主軸35の回転に拘らず停止したままである。主軸35が逆回転して回転フレーム36も逆回転している状態で主プーリ40が停止した状態を維持すると、回転フレーム36の逆回転により副プーリ56が主軸35を中心にして公転しているので、副プーリ56の公転角度に伴って主プーリ40と副プーリ56との間の位相に差が生じ、この位相差により両プーリに掛け渡し無端ベルト57の一方と他方との間で張力の差が生じ、これにより副プーリ56が回転する。このため、容器54は、回転フレーム36の回転により公転しながら自転する。なお、本実施形態では、主プーリ40と副プーリ56との減速比を2.5:1に設定してあるので、容器54は公転回転数の2.5分の1で自転する。この減速比は、両プーリの大きさを変化させることにより適宜設定することができる。
【0031】
この様に、本実施形態における脱泡装置30は、主軸35の回転方向を切り換えるだけで、容器54を公転しながら自転させる状態と、自転することなく公転させる状態とに切り換えることができる。
【0032】
次に、上記した構成からなる脱泡装置30を使用して脱泡する場合、例えばエポキシ系樹脂液など粘性が高くて内部の泡が浮上しにくい液体の脱泡処理について説明する。
まず、両容器54内に脱泡処理する液体を同じ量(同じ重量)ずつ入れ、蓋をしてから容器ホルダ37にセットする。この状態でモータ42を作動して主軸35を時計方向に公転させると、一方向クラッチ41の作用により主プーリ40の回転が許容されて主プーリ40が主軸35と共に回転するので、容器54は自転することなく公転する。容器54が公転すると、容器54内の液には公転による遠心力が作用し、本実施形態では2000R.P.Mで約600Gの遠心力が発生する。そして、容器54が45°内側に傾斜しているので、内部の液体には上記600Gの遠心力で容器54の内面に押圧され、この押圧力の分力が内面の傾斜により下方にも作用する。したがって、容器54内の液体の比重が結果的に急増した状態と同じ現象が発生し、この現象によって液体中に含まれている気泡(泡)の浮力が増大し、これにより小さな泡も液面に向かって移動する。
【0033】
そして、タイマーに設定した所定時間が経過すると、液体中に含まれていた泡は最終的には液面から大気中に押し出され、液体中に泡が残らない。このため、液体を静止した状態で消えないような泡であっても遠心力を加えることにより短時間で確実に泡を消すことができる。
【0034】
なお、容器54が公転しても自転しないので、容器54内の液体は殆ど流動することがない。したがって、大きな攪拌混合作用を期待することはできない。このため、この処理では、攪拌混合を必要としない液体の脱泡処理に適する。
【0035】
次に、液体を攪拌混合しながら脱泡する処理、例えば、2種類の液体を混合してから使用する接着剤など複数種類の液体を攪拌混合するとともに脱泡処理を行う場合について説明する。
まず、配合割合に沿って第1液と第2液を一方の容器54に入れる。そして、他方の容器54にも同じ量(同じ重量)だけ第1液と第2液を入れる。これで両方の容器54内には予め定められた配合割合で第1液と第2液が入れられて両容器54の重量が同じになる。
【0036】
容器54内に液を入れたならば蓋をしてから容器ホルダ37に装着する。この状態でモータ42を作動して主軸35を反時計方向に公転させると、一方向クラッチ41の作用により主プーリ40の回転が禁止されて停止したまま主軸35だけが回転するので、容器54は自転しながら公転する。容器54が自転しながら公転すると、容器54内の液には公転による遠心力が作用し、しかも容器54が45°内側に傾斜しているので、前記した時計方向に回転した場合と同様に、液体中に含まれている気泡(泡)の浮力が結果的に増大して小さな泡までも液面に向かって移動しようとする。これにより、泡消し作用を期待することができる。
【0037】
ここで、容器54は公転するばかりでなく45°傾斜した副軸39を中心にして自転しているので、この容器54の自転により内部の液体に自転による遠心力も作用する。したがって、容器54内の液体は、公転による遠心力を受けて公転軌跡の外側に向かって押圧されるとともに45°の傾斜により下方に向かう力も受け、尚且つ自転の遠心力により容器54の内周面に押し付けられる。このため、液体には様々な方向への力が作用し、複雑に流動し、これにより攪拌混合が行われる。
【0038】
この様にして、容器54を公転しながら自転させると、内部の液体を攪拌混合しながら脱泡処理を行うことができる。そして、容器54に入れる液体の量、粘性など液体の特性を考慮してタイマーに設定する時間を適宜設定する。
【0039】
なお、液体が容器54内で複雑に流動して攪拌混合を行うと、液面側から下方に流動することもあるので、浮上しようとしている泡が流動により再度下降することもある。したがって、容器54を自転すると、攪拌混合作用を期待することができるが、その一方で、自転しない場合よりも泡消し作用は減少する。このため、攪拌混合する処理も同時に行う場合には容器54を公転しながら自転させる方が有利であるが、攪拌混合する必要がない場合には、容器54を自転することなく公転するだけの方が有利である。
【0040】
前記した実施形態における脱泡装置30は、回転フレーム36に2つの容器54を、主軸35を中心にして同じ距離だけ離れた位置に設け、両容器54内に同じ重さの液体を入れバランスを採りながら処理するようにしたので、容器54が1つの場合に比較して、一度に2倍の液を処理することができるし、また、カウンターバランスウエイトの調整も必要ないので操作も容易である。容器54の数は、2つに限定されるものではなく、回転フレーム36に、主軸35を中心とする同心円上の周方向に等間隔で複数の副軸39を配置し、各副軸39に容器ホルダ37を設けるとともに容器54を装着するようにすれば、3個、4個…と多くの容器54を設けることができる。また、容器54を1つ設ける場合には、回転フレーム36に、主軸35を中心とする回転中心から外れた位置に副軸39を配置し、この副軸39に設けた容器ホルダ37に容器54を装着し、この容器54等に見合ったカウンターバランスウエイトを、例えば主軸35を挟んだ反対側に設ければよい。
【0041】
また、前記した実施形態では主軸35を揺動支持機構34で回転自在な状態で支え、この揺動支持機構34の下部にモータ42を吊り下げる状態で取り付けることによりモータ42の自重を主軸35の復元力として利用し、スタート時に主軸35が多少揺動した場合にもセンターに迅速に収束するように構成したが、本発明は主軸35を揺動支持機構34によって直接回転自在な状態で支える構成に限定されるものではなく、少なくとも回転フレーム36及び主軸35を含む回転部分を揺動可能な状態で支持することができる揺動支持機構34を備えていればよい。そして、揺動支持機構34の支持部材は、主軸の軸線上に設けられて主軸を介して回転部分の重さを受けることができ、所定の鍔部を備えていればどのような構成でもよい。
【0042】
例えば、図5に示す脱泡装置30の他の実施形態は、アンダーベース板60のほぼ中央に、鍔部43を有する揺動支持軸61を支持部材として設け、該揺動支持軸61の途中に形成した鍔部43を、前記揺動支持機構34と同様に、上下からゴムリング板45a,45bで挟み付けて揺動支持軸61が回転できない状態で立設し、上方に突出した揺動支持軸61の上端にブラケット62を介して揺動フレーム63を取り付け、この揺動フレーム63の内部にモータ42を出力軸を上に向けて設け、揺動フレーム63から上方に突出したモータ42の出力軸に主軸35を接続し、主軸35の上端に前記実施形態と同様の回転フレーム36を固定し、主軸35には主プーリ40を独立した状態で回転自在に設け、揺動フレーム63の一側に設けた一方向クラッチ41のプーリと主プーリ40との間に段付き無端ベルト59を掛け渡し、回転フレーム36の両側に設けた副軸39の副プーリ56と主プーリ40との間に断面略円形の無端ベルト57を掛け渡してある。
【0043】
なお、本実施形態における鍔部43は、前記実施形態における鍔部43と同様に、中心側から外周縁側に向けて厚みを次第に薄くしてある。また、この鍔部43を上下から挟み付けるゴムリング板45a,45bは、無負荷状態では厚さが均一である。そして、鍔部43の下面を支えるゴムリング板45bにはアンダーベース板60の下面から回り止めピン50を差し、また、このゴムリング板45bから鍔部43にも回り止めピン50を差して不用意に回転することを防止してある。
【0044】
この様な構成からなる脱泡装置30において、揺動支持軸61の鍔部43がゴムリング板45によって鍔部43の外周縁側から中心側に移るに連れて次第に強い力で挟み付けられているので、前記実施形態と同様に、揺動支持軸61が垂直に起立しようとする復元力が常に働いており、回転フレーム36を回転し始めた際に主軸35と回転フレーム36が揺れる時には、揺動支持軸61から上の回転部分、即ち揺動フレーム63、主軸35、及び回転フレーム36等が揺動フレーム63やモータ42などと一体になって揺動する。そして、この揺動は、鍔部43及び両ゴムリング板45a,45bの復元作用により次第に収束し、回転フレーム36が高速回転する頃には揺動支持軸61が垂直に起立することにより主軸35が垂直になり、回転フレーム36が水平方向に回転する。
【0045】
なお、本願発明は、モータの出力軸に接続された縦方向の主軸の上部に固定された回転フレームと、回転フレームに、上部を主軸側に傾斜した状態で回転自在に取り付けられた副軸と、この副軸に取り付けられた容器ホルダと、を備え、上記回転フレーム及び主軸を含む回転部分を揺動可能な状態で支持する揺動支持機構を設けたものであれば、どのような構成でもよい。また、弾性板材は、ゴムリング板に限らず、弾性力により鍔部を押圧できればよい。
【0046】

BACKGROUND OF THE INVENTION
The present invention relates to a defoaming apparatus for removing bubbles contained in a liquid having a high viscosity.
[0002]
[Prior art]
As shown in FIG. 6, the conventional defoaming device is provided with a horizontal base 2 inside the housing 1, a main shaft 3 is provided in the vertical direction at the approximate center of the base 2, and the lower end of the main shaft 3 is a rubber lump. 4, supported at the bottom of the housing 1, thin wire ropes 5 are obliquely stretched between the outer periphery of the base 2 and the housing 1, and a rotation motor 6 and a revolving motor are sandwiched between the main shaft 3. 7 is attached to the left and right sides of the base 2, the output shafts of the motors 6 and 7 are projected above the base 2, a horizontally long rotating frame 8 is fixed to the upper part of the main shaft 3, and one end of the rotating frame 8 is fixed. The countershaft 9 is provided with the upper portion inclined to the main shaft 3 side, the container holder 10 is fixed to the upper portion of the subshaft 9, and the counter balance weight 11 is provided at the other end of the rotating frame 8 with the main shaft 3 interposed therebetween. The counter balun is provided so that it can move in the radial direction. An idle shaft 12 is provided vertically below the weight 11 so as to pass through the rotary frame 8, and an upper idle pulley 13 is fixed to the upper end of the idle shaft 12 protruding above the rotary frame 8. The endless belt 14 is stretched between a holder pulley formed on the outer peripheral surface of the holder 10 and the middle of the endless belt 14 is hung on a direction changing roller 15 disposed at the rotation center of the rotating frame 8 so as to protrude below the rotating frame 8. A lower idle pulley 16 is fixed to the lower end of the idle shaft 12, and an endless belt 18 is stretched between the lower idle pulley 16 and a rotation pulley 17 fitted to the main shaft 3 via a bearing. An endless belt 19 is stretched between the pulley 17 for rotation and the pulley of the motor 7 for rotation, and the revolution pulley 20 fixed to the main shaft 3 and the revolution It is passing over the endless belt 21 between the pulley of the motor 6.
[0003]
In the defoaming device having such a configuration, when the revolving motor 6 is operated, the main shaft 3 rotates and the rotating frame 8 rotates, and the container set in the container holder 10 by the rotation of the rotating frame 8 is the main shaft 3. Rotate on the circumference centered on When the rotation motor 7 is excited, a rotational force is applied to the container holder 9 by the action of the endless belt 19, the rotation pulley 17, the endless belt 18, both idle pulleys 12, 16, and the endless belt 14. Rotates around the auxiliary shaft 9, that is, rotates.
Even if the counter balance weight 11 is adjusted, balance cannot be achieved at the time of low-speed rotation when the rotating frame 8 starts to rotate. Therefore, the rotating frame 8, the main shaft 3 and the like swing, and this swing is caused by the elasticity of the rubber mass 4. The force and the tension of the wire rope 5 are received, thereby preventing the entire apparatus from vibrating greatly. When the rotational speed of the rotating frame 8 reaches a predetermined rotational speed, the direction of the main shaft 3 is stabilized in the vertical direction due to balancing by the counter balance weight 11 and the gyro effect.
[0004]
[Problems to be solved by the invention]
However, in a configuration in which the main shaft and the base are elastically supported by a rubber lump interposed on the lower end side of the main shaft, and the main shaft is swingably supported by the tension of the wire rope obliquely stretched on the outer peripheral edge of the base, Since the tension of multiple wire ropes is used for the urging force to raise the main shaft in the vertical direction, the wire rope may stretch and loosen due to aging, etc., and the balance of the pulling force against the base may be lost. is there.
[0005]
In this way, in the swing support structure using the tension of the wire rope, if the tension of the wire rope is insufficient or the balance of the tension of each wire rope is lost (when it becomes uneven), the base will not shake. On the other hand, inconveniences that are increased tend to occur.
In addition, it is difficult to balance the tension of a plurality of wire ropes over many years, and maintenance is troublesome.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing the configuration of the first embodiment of the defoaming device 30, and FIG. 2 is a cross-sectional view showing the main part thereof.
[0012]
The defoaming device 30 is provided with a processing chamber 32 overlaid on a housing 31, and a base 33 extending in the horizontal direction is constituted by the ceiling surface of the housing 31 and the floor surface of the processing chamber 32. A swing support mechanism 34 is provided in a state where a part is inserted into a through-hole opened in the center, and a main shaft 35 is provided in a vertical direction while the lower portion is supported by the swing support mechanism 34 and is rotated to the upper end of the main shaft 35. A frame 36 is fixed, and a rotating shaft 36 is provided with a countershaft 39 for attaching a container holder 37 at the upper portion thereof with the upper portion inclined toward the main shaft 35, and a main shaft 35 near the rotating frame 36 is provided outside via a bearing. A pulley 40 is provided so as to be rotatable independently of the main shaft 35, a one-way clutch 41 for controlling the rotation direction of the main pulley 40 is provided on one side of the base 33, and a motor 42 provided inside the housing 31 is provided. Output shaft The lower end of the shaft 35 through the coupling is connected.
[0013]
The swing support mechanism 34 is a mechanism that supports a rotating portion such as the main shaft 35 and the rotary frame 36 in a swingable state, and a bearing body as a support member having a flange 43 on the outer peripheral surface and having a bearing inside. 44, an upper rubber ring plate 45a and a lower rubber ring plate 45b as elastic plate members respectively in contact with the upper surface and the lower surface of the flange 43, and the upper rubber ring plate 45a and the lower rubber ring plate 45b are connected to the upper surface of the flange 43. It comprises a holder 46 that is held between the lower surface and pressed.
[0014]
The holder 46 includes a metal pressing member 47 that presses the upper rubber ring plate 45a from above, a base 49 that is fixed on the base 33 and to which the pressing member 47 is attached, and a base on which the lower rubber ring plate 45b is placed. 33 also constitutes a part thereof.
[0015]
The flange portion 43 has a disk shape with a thickness gradually reduced from the center side (base end side) toward the outer peripheral edge side, and is disposed substantially at the center of the vertical length of the cylindrical portion of the bearing body 44.
[0016]
The rubber ring plate 45 that sandwiches the flange portion 43 is an elastic rubber plate material having a uniform thickness in a no-load state (natural state where no external force is applied). Accordingly, when the flange portion 43 is sandwiched between the lower rubber ring plate 45b and the upper rubber ring plate 45a and pressed by the pressing member 47 from above, both the rubber ring plates 45 come into contact with the thick portion of the flange portion 43. The portion is strongly compressed, and the portion in contact with the thin portion is weakly compressed. In other words, as shown in FIG. 4A, the portion closer to the bearing body 44 (center side) of the flange portion 43 is held with a stronger force, and the holding force is gradually weakened toward the outer peripheral side. Yes.
[0017]
In this way, when the flange 43 is sandwiched with a gradually increasing force as the rubber ring plate 45 approaches the center side from the outer peripheral edge side by the elastic force, when the bearing body 44 swings due to the swing of the main shaft 35, The swinging motion is centered on the intersection of the bearing body 44 and the flange portion 43, but when the flange portion 43 swings integrally with the bearing body 44, the force that the flange portion 43 compresses the rubber ring plate 45. (The force to fall, the fall force) changes according to the distance from the center according to the principle of lion. That is, as shown in FIG. 4 (b), the rubber ring plate becomes a large force in which the force that tends to fall as it approaches the center side (bearing body 44 side) from the outer peripheral edge side of the flange portion 43 gradually increases. 45 is compressed, and the rubber ring plate 45 is compressed with the strongest force near the center of the flange 43.
[0018]
On the other hand, when the rubber ring plate 45 is observed, the flange portion 43 is sandwiched (pushed back) with a strong force as it approaches the center side from the outer peripheral edge of the flange portion 43. Therefore, the pushing-back force according to the inclination of the strength of the tilting force at each part of the collar part 43 acts on the collar part 43, and the collar part 43 is initially set by the force according to the tilting force at each part of the collar part 43. Therefore, even if the bearing body 44 swings, the swing is quickly converged. And the collar part 43 is disk shape, and the rubber ring board 45 has pinched the upper and lower surfaces of the disk shaped collar part 43 over the perimeter surface. For this reason, even if the main shaft 35 is tilted in any direction, the elastic force of the upper and lower rubber ring plates 45 stably acts as a pushing-back biasing force on the flange portion 43, so that the main shaft 35 rises quickly in the initial vertical direction. To do.
[0019]
Here, when the upper and lower surfaces of the collar portion having a uniform thickness are sandwiched between the rubber ring plates as compared with the case where the collar portion has a uniform thickness, the portions are sandwiched with the same strength. When the bearing main body 44 swings in this state and the flange presses the rubber ring plate, the displacement amount (moving length) of the outer periphery of the flange is large, so the rubber ring plate is compressed by the length, It is pushed back by a force (restoring force) according to this compression. On the other hand, since the amount of displacement is smaller than that of the outer peripheral edge in the region closer to the center than the outer peripheral edge of the flange, the force (restoring force) pushed back by the rubber ring plate in this portion is weak, and the amount of displacement in the vicinity of the bearing body 44 is small. However, since there is very little, substantial resilience cannot be expected. In this way, if the clamp is held with the same force regardless of the part of the buttocks, the total restoring force is smaller than that of the present embodiment, and the restoring force when the main shaft is swung is weak. Therefore, in this embodiment, the main shaft 35 can be quickly erected in the vertical direction to achieve stable rotation earlier.
[0020]
In the present embodiment, the non-rotating pin 50 is inserted between the base 33 and the lower rubber ring plate 45b and between the lower rubber ring plate 45b and the flange portion 43 so that these members are inadvertently surrounded. It is prevented from rotating in the direction.
[0021]
In this embodiment, the motor mounting base 51 is fixed to the lower end surface of the bearing body 44 with a bolt, and the motor 42 is fixed to the lower surface of the motor mounting base 51. Accordingly, the own weight of the motor 42 acts on the bearing body 44 without acting on the housing 31, and the own weight is added to the urging force (restoring force) by the rubber ring plate 45, and this total force is swung and converged of the main shaft 35. Acts as a force and anti-vibration force. Therefore, the main shaft 35 can be erected in the vertical direction with a stronger force than when the upper and lower rubber ring plates 45 are pushed back and biased.
[0022]
Next, the rotating frame 36 will be described.
The rotary frame 36 is an aluminum frame body that is a horizontally long trapezoidal shape when viewed from the front and is rectangular when viewed from above, and the center of the lower surface portion (that is, the center of the rotary frame 36) is fixed to the upper end flange portion of the main shaft 35 with bolts. The counter shaft bearings 52 are respectively provided on the inclined surfaces at both ends inclined by about 45 °, and the direction changing roller 53 is rotatably provided on the lower surface portion in the vicinity of the inclined surface. The direction changing roller 53 is provided with the axial direction directed in the width direction of the rotary frame 36, and provided with a vertical difference according to the vertical dimension difference of the belt groove of the main pulley 40 described later.
[0023]
The sub-shaft bearing 52 closes the lower end opening of the cylindrical body integrally molded with the rotary frame 36 with a lid, and provides the bearings in the upper and lower portions, and rotatably supports the sub-shaft 39 by both bearings. When the auxiliary shaft 39 is rotatably provided by the auxiliary shaft bearing 52, both the auxiliary shafts 39 are located on the rotary frame 36 at positions away from the center of rotation about the main shaft 35 by the same distance, that is, centered on the main shaft 35. Are arranged at equal intervals of 180 ° in the circumferential direction on the concentric circles, and are attached rotatably with the upper portion inclined 45 ° toward the main shaft 35 side. And the container holder 37 is fixed to the upper end which protruded inside the rotating frame 36 of each countershaft 39. As shown in FIG.
[0024]
The container holder 37 is a member that supports a container 54 that contains a liquid to be processed. In this embodiment, three claw pieces 55 are projected upward at the same interval on the upper end of a cylindrical body that accommodates the container 54. is there. Therefore, when the container 54 is stored in the container holder 37, the claw piece 55 is engaged in the engagement groove of the container 54, and the container 54 in the container holder 37 can be rotated by the rotation of the auxiliary shaft 39.
[0025]
Further, a sub pulley 56 is fixed to the lower end of the sub shaft 39 projecting from the lid constituting the lower end of the sub shaft bearing 52, and the cross section is circular between the sub pulley 56 and the main pulley 40 provided on the main shaft 35. The endless belt 57 is stretched in a state where the endless belt 57 is passed under the direction changing roller 53.
[0026]
The main pulley 40 is coaxially attached to the upper portion of the main shaft 35 so as to be independently rotatable with respect to the main shaft 35 by two upper and lower bearings, and three belt grooves are formed on the outer peripheral surface. . Of the three belt grooves, the upper two are grooves for hanging the endless belt 57 hung on the sub pulley 56. The cross section is substantially semicircular, and is formed at a lower position slightly apart from these belt grooves. One is for connection with the one-way clutch 41, and unevenness corresponding to the step of the stepless endless belt 59 is formed. Therefore, as shown in FIG. 2, the endless belt 57 hung on the upper belt groove is hung on the auxiliary pulley 56 on the higher direction changing roller 53 side, and the endless belt 57 hung on the belt groove located therebelow. Is wound around the sub pulley 56 on the lower direction changing roller 53 side, and the stepped endless belt 59 hung on the belt groove at the lowest position is hung on the pulley of the one-way clutch 41.
[0027]
The one-way clutch 41 is a mechanism that prohibits the rotation direction of the main pulley 40 in one direction and allows the other direction. A stepless endless belt 59 is stretched between the pulley attached to the shaft of the one-way clutch 41 and the main pulley 40.
[0028]
Accordingly, when the main pulley 40 receives a rotational force from the main shaft 35, for example, if it receives a clockwise positive rotation force, the main pulley 40 is allowed by the one-way clutch 41 and rotates together with the main shaft 35 in the clockwise direction (co-rotation). )can do. When the main pulley 40 rotates together with the main shaft 35 in the same direction, a phase difference does not occur between the main pulley 40 and the sub pulley 56 connected by the endless belt 57, and couples may be generated in both pulleys. The endless belt 57 is not moved (transmission of rotational force), and the auxiliary shaft 39 does not rotate. For this reason, the container holder 37 attached to the auxiliary shaft 39 does not rotate (rotate) around the auxiliary shaft 39, and the container 54 only rotates around the main axis 35 of the rotating frame 36, that is, revolves. .
[0029]
In other words, when the main shaft 35 is rotated in the forward direction, the rotating frame 36 rotates about the main shaft 35, and thereby the container 54 revolves around the main shaft 35. Since 39 does not rotate, the container 54 does not rotate.
[0030]
On the other hand, when the counterclockwise rotational force is received from the main shaft 35, the main pulley 40 is in a state in which reverse rotation is prohibited by the action of the one-way clutch 41 via the stepless endless belt 59. It remains stopped despite the rotation. If the main pulley 40 is maintained in a state where the main shaft 35 rotates in the reverse direction and the rotating frame 36 also rotates in the reverse direction, the sub pulley 56 revolves around the main shaft 35 due to the reverse rotation of the rotating frame 36. Therefore, a difference occurs in the phase between the main pulley 40 and the sub pulley 56 with the revolution angle of the sub pulley 56, and the tension difference between one end of the endless belt 57 is passed over both pulleys by this phase difference. A difference arises, and thereby the sub pulley 56 rotates. For this reason, the container 54 rotates while revolving by the rotation of the rotating frame 36. In the present embodiment, since the reduction ratio between the main pulley 40 and the sub pulley 56 is set to 2.5: 1, the container 54 rotates at 1/2 of the revolution speed. This reduction ratio can be appropriately set by changing the sizes of both pulleys.
[0031]
As described above, the defoaming device 30 according to the present embodiment can be switched between a state in which the container 54 rotates while revolving and a state in which the container 54 revolves without rotating only by switching the rotation direction of the main shaft 35.
[0032]
Next, when defoaming is performed using the defoaming apparatus 30 having the above-described configuration, for example, a defoaming process for a liquid such as an epoxy resin liquid that has a high viscosity and is difficult to raise the internal foam will be described.
First, the same amount (the same weight) of liquid to be defoamed is placed in both containers 54, covered, and then set in the container holder 37. When the motor 42 is operated in this state to cause the main shaft 35 to revolve clockwise, the rotation of the main pulley 40 is allowed by the action of the one-way clutch 41 and the main pulley 40 rotates together with the main shaft 35, so that the container 54 rotates. Revolve without doing. When the container 54 revolves, a centrifugal force due to the revolution acts on the liquid in the container 54, and in this embodiment, a centrifugal force of about 600 G is generated at 2000 R.PM. Since the container 54 is inclined 45 ° inward, the liquid inside is pressed against the inner surface of the container 54 by the centrifugal force of 600 G, and the component force of this pressing force also acts downward due to the inclination of the inner surface. . Therefore, the same phenomenon as the state in which the specific gravity of the liquid in the container 54 suddenly increases as a result occurs, and this phenomenon increases the buoyancy of bubbles (bubbles) contained in the liquid. Move towards.
[0033]
When a predetermined time set in the timer elapses, the bubbles contained in the liquid are finally pushed out from the liquid surface to the atmosphere, and no bubbles remain in the liquid. For this reason, even if it is a bubble which does not disappear in the state where the liquid is stationary, it can be surely erased in a short time by applying centrifugal force.
[0034]
Since the container 54 does not rotate even if it revolves, the liquid in the container 54 hardly flows. Therefore, a large stirring and mixing action cannot be expected. For this reason, this process is suitable for a liquid defoaming process that does not require stirring and mixing.
[0035]
Next, a process of defoaming while stirring and mixing the liquid, for example, a case where a plurality of liquids such as an adhesive to be used after mixing two types of liquid are stirred and mixed and a defoaming process is performed will be described.
First, the first liquid and the second liquid are put into one container 54 according to the blending ratio. Then, the same amount (the same weight) of the first liquid and the second liquid is also put in the other container 54. Thus, the first liquid and the second liquid are put in both containers 54 at a predetermined blending ratio, and the weights of both containers 54 are the same.
[0036]
After the liquid is put into the container 54, the container 54 is put on and then attached to the container holder 37. When the motor 42 is operated in this state to cause the main shaft 35 to revolve counterclockwise, the rotation of the main pulley 40 is prohibited by the action of the one-way clutch 41 and only the main shaft 35 rotates while stopping, so the container 54 is Revolves while rotating. When the container 54 revolves while rotating, the centrifugal force due to the revolution acts on the liquid in the container 54, and the container 54 is inclined 45 ° inward. As a result, the buoyancy of bubbles (bubbles) contained in the liquid increases, and even small bubbles try to move toward the liquid surface. Thereby, it is possible to expect a defoaming action.
[0037]
Here, the container 54 not only revolves but also rotates around the countershaft 39 inclined by 45 °, so that the centrifugal force due to the rotation also acts on the internal liquid by the rotation of the container 54. Therefore, the liquid in the container 54 receives the centrifugal force due to the revolution and is pressed toward the outside of the revolution locus and receives a downward force due to the inclination of 45 °, and the inner circumference of the container 54 by the centrifugal force of the rotation. Pressed against the surface. For this reason, forces in various directions act on the liquid and flow in a complicated manner, whereby stirring and mixing are performed.
[0038]
In this manner, when the container 54 rotates while revolving, the defoaming process can be performed while stirring and mixing the liquid inside. Then, the time set in the timer is appropriately set in consideration of the characteristics of the liquid such as the amount and viscosity of the liquid put into the container 54.
[0039]
If the liquid flows in a complicated manner in the container 54 and is stirred and mixed, the liquid may flow downward from the liquid surface side, so that the bubbles that are about to rise may fall again due to the flow. Therefore, when the container 54 rotates, a stirring and mixing action can be expected, but on the other hand, the foam eliminating action is reduced as compared with the case where the container 54 does not rotate. For this reason, when the process of stirring and mixing is performed simultaneously, it is advantageous to rotate the container 54 while revolving. However, when it is not necessary to perform stirring and mixing, the container 54 is simply rotated without rotating. Is advantageous.
[0040]
In the defoaming device 30 in the above-described embodiment, two containers 54 are provided on the rotary frame 36 at positions separated from each other by the same distance with the main shaft 35 as the center. Since processing is performed while collecting, it is possible to process twice as much liquid at a time as compared with the case where there is one container 54, and it is also easy to operate because there is no need to adjust the counterbalance weight. . The number of containers 54 is not limited to two. A plurality of auxiliary shafts 39 are arranged on the rotating frame 36 at equal intervals in a circumferential direction on a concentric circle with the main shaft 35 as the center. If the container holder 37 is provided and the container 54 is attached, a large number of containers 54 can be provided. When one container 54 is provided, the auxiliary shaft 39 is disposed on the rotary frame 36 at a position deviating from the center of rotation about the main shaft 35, and the container 54 is placed on the container holder 37 provided on the auxiliary shaft 39. And a counter balance weight corresponding to the container 54 or the like may be provided on the opposite side of the main shaft 35, for example.
[0041]
In the above-described embodiment, the main shaft 35 is supported by the swing support mechanism 34 in a freely rotatable state, and the motor 42 is attached to the lower portion of the swing support mechanism 34 in a suspended state, whereby the weight of the motor 42 is reduced. Although it is used as a restoring force so that the main shaft 35 converges to the center quickly even when the main shaft 35 slightly swings at the start, the present invention supports the main shaft 35 in a freely rotatable state by the swing support mechanism 34.

Good. Further, the elastic plate material is not limited to the rubber ring plate, and any elastic plate material may be used as long as the collar portion can be pressed by an elastic force.
[0046]
【The invention's effect】
As described above, the present invention has the following effects.
According to the first aspect of the present invention, the swing support mechanism that supports the rotating portion including the rotary frame and the main shaft in a swingable state is provided, and the swing support mechanism is provided on the axis of the main shaft. A vertical support member having an outer peripheral surface with a flange portion that receives at least the weight of the rotating portion and gradually decreases in thickness from the center side toward the outer peripheral edge side, and an upper surface and a lower surface of the flange portion, respectively. The elastic plate member that is in contact with the holder and holding the elastic plate member in a state where the elastic plate member is sandwiched and pressed between the upper surface and the lower surface of the collar portion, and the elastic force of the elastic plate member is a biasing force that causes the main shaft to stand vertically. Therefore, compared with the conventional apparatus using a wire rope, durability can be improved and maintenance is also easy.
[0047]
And since the upper and lower surfaces of the collar part gradually thinned from the center side to the outer peripheral edge side are sandwiched by the elastic plate material, the gripping force is gradually increased as it moves from the outer peripheral edge of the collar part to the center side. Can do. Accordingly, when the collar portion is tilted by the swing of the main shaft, it is possible to apply a pushing back force according to the force that falls at each part of the collar portion, and it is possible to quickly return the main shaft to the vertical direction with a total restoring force. . For this reason, it is possible to shorten the transition time and unstable rotation time from when the motor is started until the rotating frame stably rotates horizontally, and to perform defoaming processing in a shorter time than in the prior art. .
[0048]
According to the second aspect of the present invention, the swing support mechanism is provided on the horizontal base, the lower part of the main shaft protruding upward from the base is supported by the support member, and the motor disposed below the base is mounted on the support member. Since the weight of the motor supported by the lower part is added as an urging force for raising the main shaft in the vertical direction, the main shaft can be urged in the vertical direction using the elastic force of the elastic plate and the weight of the motor. it can. Therefore, even if the main shaft is swung, the time required for returning to the vertical direction can be further shortened.
[0050]
Claim 3 According to this invention, since the collar portion is formed in a concentric disk shape whose center is aligned with the center of the support member, a stable restoring force can always be applied regardless of the inclination direction of the main shaft. Therefore, the swinging spindle returns smoothly in the vertical direction in a short time.
