【発明の属する技術分野】
本発明は、自転公転式の攪拌脱泡装置に係り、特に少量の被混練材料の攪拌脱泡を好適に行うことができる攪拌脱泡装置、被混練材料の収納容器及び攪拌脱泡方法に関する。
【０００２】
【従来の技術】
従来より、自転公転式の攪拌脱泡装置として、被混練材料を収納した容器を容器ホルダー内に保持し、この容器ホルダを自転軸線及び公転軸線の周りに自転及び公転させて、被混練材料の攪拌(混練)及び脱泡を行う装置が知られている。
【０００３】
ここで、従来の攪拌脱泡装置としては、図１１に示すものを例示できる。
この攪拌脱泡装置１０は、支持体１１に支持された公転モータ１２と、公転モータ１２の回転軸１２ａに嵌着され、公転モータ１２の駆動で回転する回転体１３と、回転体１３上に設けられた、容器１４を保持するための保持ホルダ１５と、を備え、公転モータ１２の駆動で回転体１３が回転するのに伴い、保持ホルダ１５が公転モータ１２の回転軸１２ａの周りを公転するようになっている。
【０００４】
また、この攪拌脱泡装置１０は、支持体１１に支持された自転モータ１６と、公転モータ１２の回転軸線に対して所定角度（約４５度）傾斜させて配設された、容器１４を保持するための保持ホルダ１５と、自転モータ１６の回転を保持ホルダ１５に伝達するための複数のプーリ１７ａ〜１７ｆ、及び各プーリ１７ａ〜１７ｆ間に架け渡されたベルト１８ａ〜１８ｃと、を備え、自転モータ１６の回転が、プーリ１７ａ〜１７ｆに架け渡されたベルト１８ａ〜１８ｃを介して保持ホルダ１５に伝達され、保持ホルダ１５が自転するようになっている。ここで、容器１４の自転軸線を公転軸線に対して約４５度傾斜させたのは、被混練材料を十分に混練すると共に被混練材料が容器１４からこぼれるのを防止するためである。
【０００５】
このように、従来の攪拌脱泡装置１０は、容器ホルダ１５を公転軸線周りに公転させると共に、公転軸線に対して所定角度傾斜した自転軸線周りに自転させることにより、容器ホルダ１５に保持された容器１４内の被混練材料を混練し、攪拌・脱泡するものである。この場合、容器１４内の被混練材料は、図１２（ａ）に示すように、公転する容器１４の外径側の隅部に溜まった状態で混練される。また、自転軸線が公転軸線に対して所定角度傾斜しているので、被混練材料を自転軸と平行な軸の回りに回転させて混ぜると共に、自転軸方向（容器の高さ方向）にも移動させて良く混ぜることができる。
【０００６】
【発明が解決しようとする課題】
しかしながら、かかる従来の攪拌脱泡装置１０においては、被混練材料が高い粘性を有し、また、一度に混練される被混練材料が少量である場合には、図１２（ｂ）に示すように、容器内壁に貼り付いて容器と共に回転してしまうので混練されず、十分に攪拌できないという問題があった。また、被混練材料の攪拌・脱泡は、公転及び自転により被混練材料に加えられる遠心力の変化の割合が大きい程、好適に行うことができるので、公転半径及び自転半径を大きく採り、また、公転回転数及び自転回転数を高くすることが好ましいが、高い攪拌脱泡効果を得ようと公転半径及び自転半径を大きくしたり、回転数を高くしようとすると、攪拌操作の際に装置に加えられる負荷が大きくなり、十分に攪拌・脱泡できないという問題があった。
【０００７】
また、攪拌脱泡装置には、図１３に示すように、回転軸２１ａを中心に矢印ＹＤ方向に回転する第１円盤２１と、第１円盤２１上に設けられ、回転軸２２ａを中心に矢印ＹＥ方向に回転する第２円盤２２とを備え、第２円盤２２上に回転軸２２ａを挟んで被混練材料を収容した一対のカプセル２３を設置し、第１及び第２円盤２１ａ，２２ａの回転により、各カプセル２３を回転軸２１ａ，２２ａ周りに矢印ＹＤ，ＹＥ方向に公転させるよう構成されたものもある。この攪拌脱泡装置によれば、回転軸２１ａ，２２ａを中心としたカプセル２３の公転運動により、被混練材料がカプセル２３内で十分に混練されるので、被混練材料を十分に攪拌できる。しかし、この構成では、カプセル２３が回転軸２１ａ，２２ａの二軸を中心として公転するので、カプセル２３内で被混練材料が激しく移動し、被混練材料に空気が混入し易く、被混練材料の脱泡までを十分に行うことができるものではなかった。
【０００８】
本発明は、前記従来技術の問題を解消し、簡単な構成により被混練材料を十分に攪拌・脱泡できる攪拌脱泡装置、被混練材料の収納容器及び攪拌脱泡方法を提供することを目的とする。
【０００９】
【課題を解決するための手段】
前記課題は、第１の手段として、被混練材料を収納した円筒内周壁を有する容器を保持部に保持し、前記保持部に保持された容器を自転軸線及び公転軸線の周りに自転及び公転させて、前記被混練材料の攪拌及び脱泡を行う装置であって、前記保持部の自転軸線と公転軸線とを平行にし、かつ、保持部の自転軸線と容器の中心軸とが一致するよう構成したことを特徴とする攪拌脱泡装置によって解決することもできる。
【００１０】
この攪拌脱泡装置は、被混練材料が収納された容器を公転軸線周りに公転させると共に自転軸線周りに自転させて、これら公転及び自転に伴う被混練材料に加えられる遠心力により、被混練材料を攪拌及び脱泡するものである。この場合、容器の内径が同じであるとすれば、容器の自転軸線を公転軸線に対して傾斜させた場合に比べ、自転軸線と公転軸線とを平行にした場合には、容器内の被混練材料が容器の自転運動に伴い公転軸線に最も近づいた場合の半径（最小公転半径）と、最も遠ざかった場合の半径（最大公転半径）との差を大きくすることができ、遠心力の変化を大きくできる。従って、公転軸線に対して自転軸線を傾斜させて構成した場合のように、容器の内周壁全周にわたって被混練材料が張り付いて十分な攪拌脱泡を行えないといった事態を回避でき、容器の自転及び公転運動により発生する遠心力により、被混練材料が容器内の公転軸から遠い側に押し付けられた状態で十分に混練され、攪拌・脱泡される。なお、ここで、平行とは、ほぼ平行であればよく、厳密に平行である必要はない。また、この攪拌脱泡装置では、保持部に保持された容器の中心軸と保持部の自転軸線とが一致するように構成して、容器を公転及び自転させるようにしてあるため、容器を２つの軸の周りを公転させる場合のように、容器内で被混練材料が激しく移動せず、被混練材料に空気が混入するのを回避できる。このため、被混練材料を十分に攪拌脱泡できる。
【００１１】
前記第１の手段を採用した攪拌脱泡装置においては、前記自転軸線を中心に自転する前記容器の円筒内周壁が、前記公転軸線を順次通過するよう構成することが好ましい。
【００１２】
ここで、公転による遠心力は、一般に公転半径に比例するので、容器内の被混練材料の最小公転半径と、最大公転半径との差が大きいほど、遠心力の変化量は大きくなる。このため、自転半径が一定であれば、最小公転半径が小さい程、遠心力の変化割合は大きくなる。従って、自転する容器の円筒内周壁が公転軸線を順次通過するようにすると、容器内の被混練材料の最小公転半径が０になるので、公転による遠心力の変化割合を最大にすることができる。加えて、容器全体の公転半径も小さくなるので、装置の負担が小さくなり、高速回転させることができる。ここで、遠心力は、角速度の２乗に比例するので、この高速回転化により遠心力及びその変化を更に大きくできる。従って、被混練材料の攪拌脱泡を最適に行える。なお、この場合、容器の円筒内周壁は、公転軸線を厳密に通過している必要はない。
【００１３】
前記第１又は第２の技術手段を採用した攪拌脱泡装置においては、第３の技術手段として、前記容器は、前記円筒内周壁の端部に開口端を有し、その開口端の内周縁に沿って、前記自転軸線に向けて突出した突縁部を備えることが好ましい。この構成によれば、自転及び公転する容器の内周壁に押し付けられた状態で攪拌脱泡される被混練材料の容器開口部からの流出を、この突縁部で規制できるため、容器に蓋を設けることなく攪拌脱泡できる。このため、容器内への被混練材料の出し入れを容易に行え、又、装置を簡略化でき、更に、攪拌脱泡操作に伴い装置に加えられる負荷を低減できる。
【００１４】
前記第１乃至第３の技術手段を採用した攪拌脱泡装置においては、第４の技術手段として、前記容器の周壁の少なくとも一部を弾性体から形成された弾性部とし、前記保持部に保持された状態で自転及び公転する前記容器の内周壁が遠心力により変形して前記保持部に押し付けられ、凹凸が形成されるよう構成することが好ましい。この攪拌脱泡装置は、被混練材料を収容する容器の少なくとも一部をシリコンゴム等の弾性体から形成すると共に、保持部の内周壁に複数の突出部を設け、又は、複数の突条を設け、更には、複数の溝を設ける等により、保持部で保持された容器の弾性部が保持部の内周壁に押し付けられて、容器内周壁に凹凸が形成されるようになっている。このように、保持部で保持された状態で自転及び公転する容器の内周壁に凹凸が形成されるよう構成することにより、容器内の被混練材料が容器内周壁の凸部を避けるよう、容器の高さ方向に移動することとなる。従って、この構成によれば、容器内の被混練材料を十分に混練でき、大きな攪拌脱泡効果を得ることができる。また、保持部から取り出された容器の弾性部は、保持部の凸部からの押圧が解けて平坦となるため、攪拌脱泡操作を行った後、容器内から被混練材料を取り出す場合にも、へら等を用いて容易に容器内から被混練材料を取り出すことができる。さらに、容器の弾性部が保持部の内周壁に押し付けられた状態で保持部に保持されるため、攪拌脱泡操作中に容器が保持部から脱落するのを防止できる。
【００１５】
【発明の実施の形態】
以下、本発明の一実施例に係る攪拌脱泡装置１を、図面を参照しつつ説明する。
攪拌脱泡装置１は、図１，２に示すように、床面等の平坦面に載置される載置板ｓの上端面にフレームｆが立設され、このフレームｆに設けられた攪拌機構部Ａで、容器２内に収納された被混練材料を攪拌脱泡するものである。
【００１６】
容器２は、図３に示すように、有底円筒状に形成されると共に、その容器２の開口縁部は、容器２の中心軸２ｂ方向に向けて突出して形成された突縁部２ａとなっている。
【００１７】
攪拌機構部Ａは、図４に示すように、被混練材料を収納する容器２を保持する容器ホルダ３と、容器ホルダ３を公転させるための公転機構部と、容器ホルダ３を自転させるための自転機構部と、から成る。
【００１８】
容器ホルダ３は、有底円筒状に形成されると共に、その底面中央部からは自転駆動ギア３ａが外方に突設され、その内周面で保持した容器２を図示しない固定手段で固定するようになっている。
【００１９】
公転機構部は、フレームｆの裏面に設けられた公転モータ４の回転軸４ａが、フレームｆに設けられた開口からフレームｆ表面側に突出し、この回転軸４ａの先端部に容器ホルダ３を保持する公転基盤４１が嵌着され、公転モータ４の回転により公転基盤４１が回転し、これにより容器ホルダ３が公転モータ４の回転軸線を公転軸線Ｋとして公転運動するようになっている。
【００２０】
ここで、公転基盤４１は、公転モータ４の回転軸４ａに対する基端部４１ａが略円柱状に形成されると共に、先端部４１ｂが基端部４１ａに比べて拡径した略円柱状に形成されている。公転基盤４１の先端面には、容器ホルダ３を保持するための保持部４１１と、保持部４１１及び保持部４１１に保持された容器ホルダ３とのバランスをとるためのバランスおもり４５を取り付けるためのおもり取付部４１２とが、公転基盤４１の公転軸線Ｋを挟んだ一方側と他方側とに設けられている。
【００２１】
保持部４１１は、公転基盤４１の先端面に開口する円形孔から構成され、容器ホルダ３を自転可能に保持するためのボールベアリング４２が、その内周面の底部付近と開口部付近とに設けられ、このボールベアリング４２を介して容器ホルダ３が自転自在に保持され、容器ホルダ３及び容器２が保持部４１１内で自転するようになっている。ここで、保持部４１１は、図４に示すように、その内周面に保持されて公転モータ４の回転により公転する容器ホルダ３内の容器２の円筒内周壁が、公転モータ４の公転軸線Ｋ上に位置すると共に、容器ホルダ３に保持された容器２の中心軸２ｂが自転軸線Ｊに一致した状態となるよう構成されている。
【００２２】
おもり取付部４１２は、公転基盤４１上に設けられた軸受４３に回転自在に支持されて公転基盤４１の径方向に沿った状態で設けられた螺子部材４４に、バランスおもり４５が螺合すると共に、公転基盤４１上に螺子部材４４に平行に設けられた図示しないキー部にバランスおもり４５外周面に設けられた図示しないキー溝が摺動自在に嵌合するようになっている。そして、螺子部材４４の基端部に設けられた調整ノブ４６を回転させて、螺子部材４４を回転させ、これに伴う螺子部材４４とバランスおもり４５との螺子動作により、バランスおもり４５が公転基盤４１の径方向に沿って移動し、公転基盤４１上での重量のバランスをとるようになっている。
【００２３】
このような構成の公転機構部では、公転モータ４の回転により公転基盤４１を回転させて、公転基盤４１の保持部４１１に保持された容器ホルダ３が、公転モータ４の回転軸４ａを公転軸線Ｋとして公転するようになっている。
【００２４】
自転機構部は、自転モータ５とその駆動力を容器ホルダ３の自転駆動ギア３ａに伝達する伝達機構から構成されている。自転モータ５は、フレームｆの裏面にかつ、公転モータ４の下方に設けられその回転軸５ａは、フレームｆに設けられた開口からフレームｆ表面側に突出し、この回転軸５ａの先端部にプーリ５１が嵌着されている。また、略円筒状の自転プーリ５２がその内周面に設けられた一対のボールベアリング４２を介して、公転基盤４１の基端部４１ａの外周面に取り付けられている。
【００２５】
自転プーリ５２は、その基端部４１ａの外周面の周方向に沿ってＶ字溝５２１が設けられ、このＶ字溝５２１にプーリ５１との間でＶベルト５３が架け渡されている。また、自転プーリ５２は、その先端部内周面に周方向に沿って設けられたインナーギア５２２を有し、容器ホルダ３の自転駆動ギア３ａがこのインナーギア５２２に噛み合っている。
【００２６】
このような構成の自転機構部では、自転モータ５の回転が回転軸５ａに嵌着されたプーリ５１を回転させ、この回転がＶベルト５３を介して自転プーリ５２に伝達される。自転プーリ５２は、公転基盤４１の基端部４１ａの外周に沿って公転基盤４１に同心して回転し、この回転に伴い自転プーリ５２の先端に設けられたインナーギア５２２に噛み合った自転駆動ギア３ａを、インナーギア５２２の回転に連動して回転させる。そして、自転駆動ギア３ａの回転に従って容器ホルダ３に保持された容器２が、その中心軸２ｂが自転駆動ギア３ａの軸線と一致した状態で、自転駆動ギア３ａを自転軸線Ｊとして自転するようになっている。
【００２７】
ここで、この攪拌脱泡装置１においては、自転機構部による容器２の自転軸線Ｊと、公転機構部による容器２の公転軸線Ｋとは、載置板ｓが載置される床面（水平面）に対してそれぞれ平行になるよう構成されている。
【００２８】
このように構成される攪拌脱泡装置１による被混練材料の攪拌脱泡は、まず、攪拌脱泡対象である被混練材料が収容された容器２を容器ホルダ３内に収納し、図示しない固定手段で容器２を容器ホルダ３内に固定して保持する。次いで、公転モータ４の回転により公転基盤４１を回転させ、公転基盤４１の保持部４１１に保持された容器ホルダ３内の容器２を、公転モータ４の回転軸４ａを公転軸線Ｋとして公転させる。そして、自転モータ５の回転をＶベルト５３を介して自転プーリ５２に伝達して、自転プーリ５２を回転させ、自転プーリ５２の回転に連動させて自転駆動ギア３ａを回転させ、容器ホルダ３に保持された容器２を、自転駆動ギア３ａの軸線を自転軸線Ｊとして自転させる。
【００２９】
このように、この攪拌脱泡装置１は、公転モータ４及び自転モータ５の回転により、容器ホルダ３内に保持された容器２が、公転モータ４の回転軸４ａを公転軸線Ｋとして公転すると共に、容器ホルダ３の自転駆動ギア３ａの軸線を自転軸線Ｊとして自転し、これにより、容器２内の被混練材料は、図４に示すように、容器２の内周壁の公転軸線Ｋから遠い側に固まった状態で混練されて攪拌・脱泡される。
【００３０】
この場合、この攪拌脱泡装置１は、公転軸線Ｋと自転軸線Ｊとを平行にして構成しているため、最大公転半径と最小公転半径との差を大きくとることができ、遠心力の変化を大きくとることができる。従って、この攪拌脱泡装置１によれば、被混練材料が高粘度や少量である場合においても、十分な攪拌脱泡を行うことができる。また、この攪拌脱泡装置１では、容器ホルダ３に保持された容器２の中心軸２ｂと自転軸線Ｊとが一致するように構成して、容器２を公転させると共に自転させるようにしてあるため、例えば、容器２を２つの軸の周りを公転させる場合のように、容器２内で被混練材料が激しく移動せず、被混練材料に空気が混入するのを回避できる。このため、被混練材料を十分に攪拌脱泡できる。
【００３１】
更に、図５に示すように、自転軸線Ｊ周りに矢印ＹＡ方向に自転する容器２は、公転軸線Ｋ周りに矢印ＹＢ方向に公転しながら、その円筒状内壁が順次公転軸線Ｋを通過するよう構成されているため、最小公転半径を最小として遠心力の変化を得ることができ、安定した動作で十分な攪拌脱泡を行うことができる。さらに、公転基盤４１等の公転機構も小さくできることから、装置の負担が小さく、公転の回転数を大きくすることができる。従って、遠心力の大きさ及び変化を更に大きくして、より高粘度、少量の被混練材料を攪拌脱泡できる。
【００３２】
このような攪拌脱泡処理により、容器２内の被混練材料を攪拌・脱泡したら、公転モータ４及び自転モータ５の回転を停止し、容器２の自転及び公転を停止する。この場合、容器２の公転動作を続けたまま、自転モータ５の回転を停止して、容器２の自転動作を終了し、次いで公転モータ４の回転を停止して、容器２の公転動作を停止するようにすると、容器２の内周壁の外径側に被混練材料を寄せたまま、装置を停止させることができる。このため、容器２内から被混練材料を取り出し易くできる。
【００３３】
また、この攪拌脱泡装置１においては、容器２の自転軸線Ｊ及び公転軸線Ｋが、載置板ｓが載置される床面（水平面）に対して平行となるよう構成されているため、容器ホルダ３に取り付けられた容器２の開口部が攪拌脱泡装置１側面に開口した状態となる。このため、攪拌脱泡されて容器２内周壁に寄せられた状態の被混練材料を取り出しやすい。また、使用者が容器２の突縁部２ａから溢れないように、容器２に収納する被混練材料の量を調節せざるを得ないことから、容器２内への被混練材料の入れすぎを防止できる。このため、適切な量の被混練材料よりも多量の被混練材料を収納すると突縁部２ａから被混練材料が溢れるよう、容器２の突縁部２ａの高さを設定することにより、適切な量の被混練材料を容器２内に収納できる。
【００３４】
このようにして十分な攪拌脱泡がなされた被混練材料は、流動性を有しているため、一般には、攪拌脱泡がなされた被混練材料を容器２内から残さずに取り出すのが容易でない。ところが、この場合でも、容器２内の被混練材料を取り出すためのへらとして、図６に示すような構成のへら６を用いることにより、容器２内壁に付着した被混練材料を容易に取り出すことができる。
【００３５】
へら６は、このへら６を用いる際に把持される把持部６ａと、被混練材料をかきとるためのかきとり部６ｂと、から成るものであるが、かきとり部６ｂは、容器２の円筒内周壁の前記突縁部２ａから底面近傍にかけての形状に対応した形状に形成されている。このため、容器２内に挿入されたかきとり部６ｂは、容器２内壁に沿って容器２内に配置された状態となり、従って、容器２内壁や隅部に付着した被混練材料を好適に取り除くことができる。
【００３６】
なお、本発明の攪拌脱泡装置は、前記実施例の攪拌脱泡装置１に限定されず、本発明の要旨を逸脱しないかぎり、適宜変更して差し支えない。例えば、前記実施例では、被混練材料が収納される容器として、単に有底筒状に構成された容器２を用いたが、図７に示すように、その内周壁の一側が他側に対して、前記突縁部７ａ側にずれた形状に形成された容器７を用いてもよい。この容器７を用いることにより、攪拌脱泡操作の際には、容器７の自転に伴い被混練材料が付着した部分での容器７の底面７ｂの位置が暫時変化するため、被混練材料が容器７の軸線方向に沿って矢印ＹＣ，ＹＣ´方向に移動しつつ攪拌され、大きな攪拌脱泡効果を得ることができる。
【００３７】
また、図８（ａ）に示すように、被混練材料を収容する容器の全体をシリコンゴム等の弾性材から形成された容器２０とすると共に、容器ホルダ３の内周壁に凹凸部としての突出部３ｂを設ける構成としてもよい。この構成によれば、図８（ｂ）に示すように、容器ホルダ３で保持されて容器２０が自転及び公転運動している状態においては、容器２０の周壁は、遠心力で変形して容器ホルダ３の内周壁に押し付けられて突出部３ｂで押圧され、凹凸が形成された状態となる。そして、図８（ｃ）に示すように、容器２０の自転運動に伴い容器２０内周壁の凸部２１に位置した被混練材料ｋは、容器２０の自転及び公転運動に伴う遠心力により容器２０内周壁に押し付けられているため、容器２０の凸部２１を避けるように移動する。このため、容器２０内の被混練材料ｋは、容器２０の凸部２１が形成された部分においては、容器２０の高さ方向に移動することとなる。従って、この構成によれば、容器２０内の被混練材料ｋを十分に混練でき、大きな攪拌脱泡効果を得ることができる。そして、容器２０の自転及び公転運動が停止すると、図８（ｄ）に示すように、容器ホルダ３による容器２０内周壁に対する押圧が解け、容器２０内周壁が平坦となるため、攪拌脱泡操作を行った後、容器２０内から被混練材料ｋを取り出す場合にも、へら等を用いて容器２０内から被混練材料ｋを容易に取り出すことができる。また、容器２０を容器ホルダ３で保持した状態においては、容器２０の周壁を容器ホルダ３の突出部３ｂで押圧した状態となるため、容器２０が容器ホルダ３に固定され、攪拌脱泡操作中に容器２０が容器ホルダ３から脱落するのを防止できる。そして、容器２０内にへらを挿入し又は容器２０内からへらを抜き出す際には、容器２０の突縁部２０ａが弾性変形するため、容器２０内の被混練材料ｋを容易に取り出すことができる。
【００３８】
なお、容器２０の内周壁に凹凸を形成するための突出部３ｂは、図８に示すように、容器ホルダ３の内周壁の互いに対向する位置の底面側と上縁側とに一つずつ設けることが好ましいが、図９に示すように、容器ホルダ３の内周壁に複数の突出部３ｂを設ける構成としてもよい。この構成によっても、容器ホルダ３で保持されて容器２０が自転及び公転運動している状態においては、図９（ｂ）に示すように、容器２０の周壁に凹凸が形成された状態となり、容器２０内の被混練材料ｋは、容器２０の凸部２１が形成された部分においては、容器２０の高さ方向に移動することとなり、容器２０内の被混練材料ｋを十分に混練でき、大きな攪拌脱泡効果を得ることができる。そして、容器２０の自転及び公転運動が停止すると、図９（ｃ）に示すように、容器ホルダ３による容器２０内周壁に対する押圧が解け、容器２０内周壁が平坦となるため、容器２０内からの被混練材料ｋの取り出しを容易に行える。また、容器全体を弾性材から形成する必要はなく、一部のみを弾性材から形成してもよい。さらに、前記実施例では、突出部３ｂを設けることにより自転及び公転運動中の容器２０の周壁に凸部２１を形成するようにしたが、図１０に示す容器ホルダ３０のように、内周壁に複数の溝３ｃを設ける構成としてもよい。
【００３９】
また、前記実施例では、容器ホルダ３の内周壁に突出部３ｂを設けることにより、容器ホルダ３に保持された状態で自転及び公転運動する容器２０の周壁に凹凸が形成されるよう構成したが、例えば、容器ホルダ３に代えて容器２０の外周面に突出部を設ける構成としてもよい。この構成によっても、容器ホルダ３に保持された状態で自転及び公転する容器２０の内周壁に凹凸が形成されるので、容器２０内の被混練材料ｋを容器２０の上下方向に移動させることができ、大きな攪拌脱泡効果を得ることができる。また、容器ホルダ３と容器２０との間に、リング状の部材や網を容器２０の外周を覆うように介在させる構成としても、容器ホルダ３に保持された状態で自転及び公転する容器２０の内周壁に凹凸が形成されるので、容器２０内の被混練材料ｋを容器２０の上下方向に移動させることができ、大きな攪拌脱泡効果を得ることができる。
【００４０】
また、前記実施例では、容器２が有底円筒状に形成されると共に、開口端部に突縁部２ａを有するものであった。しかし、円筒体の両端に開口部を設け、その両側の開口端に突縁部を有する形状に形成してもよい。また、前記実施例では、容器２を保持するための保持ホルダ３の自転軸線Ｊ、公転軸線Ｋが、床面（水平面）に対して平行となるよう構成したが、自転軸線Ｊと公転軸線Ｋとが互いに平行となるのであれば、例えば、自転軸線Ｊ、公転軸線Ｋが床面に対して垂直となるよう構成してもよい。
【００４１】
【発明の効果】
本発明に関連する攪拌脱泡装置によれば、公転軸線と自転軸線とを平行にして構成してあるため、容器の自転及び公転運動に伴い被混練材料が容器内周壁に押し付けられた状態で十分に混練され、また、被混練材料に加えられる遠心力の変化を大きくできるため、公転軸線と自転軸線とを平行にするといった簡単な構成により、十分な攪拌脱泡を行うことができる。さらに、この攪拌脱泡装置では、保持部に保持された容器の中心軸と保持部の自転軸線とが一致するように構成して、容器を公転させると共に自転させるようにしてあるため、容器を２つの軸の周りを公転させる場合のように、容器内で被混練材料が激しく移動せず、被混練材料に空気が混入するのを回避できる。このため、被混練材料を十分に攪拌脱泡できる。
【００４２】
本発明に関連する攪拌脱泡装置によれば、公転軸線と自転軸線とを平行にして構成してあるため、被混練材料が容器内周壁に押し付けられた状態で十分に攪拌・脱泡される。また、自転する容器の円筒内周壁が公転軸線を通過するようにすることにより、公転による遠心力の変化割合を最大にでき、更に容器全体の公転半径も小さくなるので、装置の負担が小さくなり、高速回転化でき、従って、被混練材料の攪拌脱泡を最適に行える。

BACKGROUND OF THE INVENTION
The present invention relates to a rotation / revolution type stirring and defoaming apparatus, and more particularly to a stirring and defoaming apparatus, a container for storing a material to be kneaded, and a stirring and defoaming method that can suitably perform stirring and defoaming of a small amount of material to be kneaded.
[0002]
[Prior art]
Conventionally, as a rotation and revolution type stirring and defoaming device, a container containing a material to be kneaded is held in a container holder, and the container holder is rotated and revolved around a rotation axis and a rotation axis to Devices that perform stirring (kneading) and defoaming are known.
[0003]
Here, as a conventional stirring and defoaming apparatus, the one shown in FIG. 11 can be exemplified.
The stirring and defoaming device 10 includes a revolving motor 12 supported by a support 11, a rotating body 13 that is fitted to a rotating shaft 12 a of the revolving motor 12, and rotates by driving of the revolving motor 12. A holding holder 15 for holding the container 14, and the holding holder 15 revolves around the rotation shaft 12 a of the revolving motor 12 as the rotating body 13 rotates by driving the revolving motor 12. It is supposed to be.
[0004]
The stirring and defoaming device 10 holds a container 14 disposed at a predetermined angle (about 45 degrees) with respect to the rotation motor 16 supported by the support 11 and the rotation axis of the revolution motor 12. A holding holder 15, a plurality of pulleys 17a to 17f for transmitting the rotation of the rotation motor 16 to the holding holder 15, and belts 18a to 18c spanned between the pulleys 17a to 17f, The rotation of the rotation motor 16 is transmitted to the holding holder 15 via the belts 18a to 18c spanned around the pulleys 17a to 17f, so that the holding holder 15 rotates. Here, the reason why the rotation axis of the container 14 is inclined about 45 degrees with respect to the revolution axis is to sufficiently knead the material to be kneaded and prevent the material to be kneaded from spilling from the container 14.
[0005]
As described above, the conventional stirring and defoaming apparatus 10 is held by the container holder 15 by revolving the container holder 15 around the revolution axis and rotating around the rotation axis inclined by a predetermined angle with respect to the revolution axis. The material to be kneaded in the container 14 is kneaded, stirred and degassed. In this case, as shown in FIG. 12A, the material to be kneaded in the container 14 is kneaded in a state where it is collected in the corner on the outer diameter side of the revolving container 14. In addition, since the rotation axis is inclined at a predetermined angle with respect to the revolution axis, the material to be kneaded is rotated and mixed around an axis parallel to the rotation axis, and also moved in the rotation axis direction (the height direction of the container). Let it mix well.
[0006]
[Problems to be solved by the invention]
However, in such a conventional stirring and defoaming apparatus 10, when the material to be kneaded has high viscosity and a small amount of material to be kneaded at a time is small, as shown in FIG. There is a problem that it is not kneaded and cannot be sufficiently stirred because it sticks to the inner wall of the container and rotates together with the container. In addition, the stirring and defoaming of the material to be kneaded can be performed more suitably as the rate of change in the centrifugal force applied to the material to be kneaded due to revolution and rotation is larger, so the revolution radius and the rotation radius are taken larger. It is preferable to increase the revolution speed and the rotation speed. However, in order to obtain a high stirring and defoaming effect, if the revolution radius and the rotation radius are increased or the rotation speed is increased, the apparatus is used during the stirring operation. There was a problem that the load to be applied became large and stirring and defoaming could not be sufficiently performed.
[0007]
Further, as shown in FIG. 13, the stirring deaerator is provided on the first disk 21 with the first disk 21 rotating around the rotation shaft 21a in the direction of the arrow YD, and the arrow about the rotation shaft 22a. A second disk 22 rotating in the YE direction, and a pair of capsules 23 containing the material to be kneaded are placed on the second disk 22 with the rotating shaft 22a interposed therebetween, and the first and second disks 21a, 22a rotate. Accordingly, there is a configuration in which each capsule 23 is revolved around the rotation axes 21a and 22a in the directions of arrows YD and YE. According to this stirring and defoaming device, the material to be kneaded is sufficiently kneaded in the capsule 23 by the revolving motion of the capsule 23 around the rotation shafts 21a and 22a, so that the material to be kneaded can be sufficiently stirred. However, in this configuration, since the capsule 23 revolves around the two axes of the rotation shafts 21a and 22a, the material to be kneaded moves vigorously in the capsule 23, and air is easily mixed into the material to be kneaded. It was not possible to sufficiently perform defoaming.
[0008]
It is an object of the present invention to provide a stirring defoaming apparatus, a container for storing the material to be kneaded, and a method for stirring and defoaming that can solve the problems of the prior art and sufficiently stir and degas the material to be kneaded with a simple configuration. And
[0009]
[Means for Solving the Problems]
As the first means, the container having a cylindrical inner peripheral wall containing the material to be kneaded is held in the holding part, and the container held in the holding part is rotated and revolved around the rotation axis and the revolution axis. An apparatus for stirring and defoaming the material to be kneaded, wherein the rotation axis of the holding part is parallel to the revolution axis, and the rotation axis of the holding part and the central axis of the container coincide with each other It can also be solved by a stirring and defoaming device characterized by the above.
[0010]
This stirring and defoaming device revolves a container containing a material to be kneaded around the revolution axis and rotates around the rotation axis, and the material to be kneaded by centrifugal force applied to the material to be kneaded along with the revolution and rotation. Is stirred and defoamed. In this case, assuming that the inner diameters of the containers are the same, compared with the case where the rotation axis of the container is inclined with respect to the revolution axis, the kneading in the container is performed when the rotation axis and the revolution axis are parallel. The difference between the radius when the material is closest to the revolution axis along with the rotation of the container (minimum revolution radius) and the radius when the material is farthest (maximum revolution radius) can be increased. Can be bigger. Therefore, as in the case where the rotation axis is inclined with respect to the revolution axis, it is possible to avoid a situation in which the material to be kneaded is stuck on the entire inner peripheral wall of the container and sufficient stirring and deaeration cannot be performed. The material to be kneaded is sufficiently kneaded and stirred and defoamed in a state where the material to be kneaded is pressed to the side far from the revolution axis in the container by the centrifugal force generated by the rotation and revolution. Here, the term “parallel” may be almost parallel, and need not be strictly parallel. Further, in this stirring and defoaming device, the container is held in the holding section so that the central axis of the container and the rotation axis of the holding section coincide with each other so that the container can revolve and rotate. As in the case of revolving around one axis, the material to be kneaded does not move vigorously in the container, and air can be prevented from being mixed into the material to be kneaded. For this reason, the material to be kneaded can be sufficiently stirred and defoamed.
[0011]
In the stirring and defoaming apparatus employing the first means, it is preferable that the cylindrical inner peripheral wall of the container that rotates about the rotation axis passes through the revolution axis in order.
[0012]
Here, since the centrifugal force due to revolution is generally proportional to the revolution radius, the amount of change in centrifugal force increases as the difference between the minimum revolution radius of the material to be kneaded in the container and the maximum revolution radius increases. For this reason, if the rotation radius is constant, the smaller the minimum revolution radius, the greater the rate of change in centrifugal force. Accordingly, when the cylindrical inner peripheral wall of the rotating container is sequentially passed through the revolution axis, the minimum revolution radius of the material to be kneaded in the container becomes 0, so that the rate of change in centrifugal force due to revolution can be maximized. . In addition, since the revolution radius of the entire container is reduced, the burden on the apparatus is reduced and the container can be rotated at a high speed. Here, since the centrifugal force is proportional to the square of the angular velocity, the centrifugal force and its change can be further increased by this high speed rotation. Therefore, stirring and defoaming of the material to be kneaded can be performed optimally. In this case, the cylindrical inner peripheral wall of the container does not need to strictly pass the revolution axis.
[0013]
In the stirring and defoaming apparatus employing the first or second technical means, as a third technical means, the container has an open end at an end of the cylindrical inner peripheral wall, and an inner peripheral edge of the open end. It is preferable to provide a projecting edge portion projecting toward the rotation axis along the axis. According to this configuration, since the outflow from the container opening of the material to be kneaded that is stirred and defoamed in a state of being pressed against the inner peripheral wall of the rotating and revolving container can be regulated by the protruding edge, the container is covered with a lid. It can be stirred and defoamed without being provided. For this reason, the material to be kneaded can be easily taken in and out of the container, the apparatus can be simplified, and the load applied to the apparatus during the stirring and defoaming operation can be reduced.
[0014]
In the stirring and defoaming apparatus adopting the first to third technical means, as a fourth technical means, at least a part of the peripheral wall of the container is an elastic part formed of an elastic body and is held by the holding part. It is preferable that the inner peripheral wall of the container that rotates and revolves in a deformed state is deformed by a centrifugal force and pressed against the holding portion to form irregularities. In this stirring and defoaming device, at least a part of a container for storing the material to be kneaded is formed of an elastic body such as silicon rubber, and a plurality of protrusions are provided on the inner peripheral wall of the holding portion, or a plurality of protrusions are provided. By providing a plurality of grooves, the elastic part of the container held by the holding part is pressed against the inner peripheral wall of the holding part, and irregularities are formed on the inner peripheral wall of the container. In this way, the container is configured so that the material to be kneaded in the container avoids the convex part of the inner peripheral wall of the container by forming irregularities on the inner peripheral wall of the container that rotates and revolves while being held by the holding part. Will move in the height direction. Therefore, according to this configuration, the material to be kneaded in the container can be sufficiently kneaded, and a large stirring and defoaming effect can be obtained. In addition, since the elastic part of the container taken out from the holding part is flattened by releasing the pressure from the convex part of the holding part, it is also possible to take out the material to be kneaded from the container after performing the stirring and defoaming operation. The material to be kneaded can be easily taken out from the container using a spatula or the like. Furthermore, since the elastic part of the container is held by the holding part while being pressed against the inner peripheral wall of the holding part, it is possible to prevent the container from falling off the holding part during the stirring and defoaming operation.
[0015]

The revolution base 41 is fitted, and the revolution base 41 is rotated by the rotation of the revolution motor 4, whereby the container holder 3 revolves around the revolution axis K of the revolution motor 4.
[0020]
Here, the revolution base 41 is formed in a substantially cylindrical shape in which a base end portion 41a with respect to the rotation shaft 4a of the revolution motor 4 is formed in a substantially cylindrical shape, and a distal end portion 41b is larger in diameter than the base end portion 41a. ing.

A weight attachment portion 412 is provided on one side and the other side of the revolution base 41 with the revolution axis K therebetween.
[0021]
The holding portion 411 is formed of a circular hole that opens at the tip surface of the revolution base 41, and ball bearings 42 for holding the container holder 3 so as to be capable of rotating are provided near the bottom and near the opening of the inner peripheral surface thereof. The container holder 3 is rotatably held via the ball bearing 42, and the container holder 3 and the container 2 are rotated in the holding portion 411. Here, as shown in FIG. 4, the holding portion 411 is held on its inner peripheral surface, and the cylindrical inner peripheral wall of the container 2 in the container holder 3 that revolves by the rotation of the revolving motor 4 is the revolving axis of the revolving motor 4. The center axis 2b of the container 2 held by the container holder 3 is configured to coincide with the rotation axis J while being positioned on K.
[0022]
The weight attaching portion 412 is rotatably supported by a bearing 43 provided on the revolution base 41 and a balance weight 45 is screwed onto a screw member 44 provided in a state along the radial direction of the revolution base 41. A key groove (not shown) provided on the outer peripheral surface of the balance weight 45 is slidably fitted to a key portion (not shown) provided parallel to the screw member 44 on the revolution base 41. Then, the adjustment knob 46 provided at the base end portion of the screw member 44 is rotated to rotate the screw member 44, and the screw operation of the screw member 44 and the balance weight 45 accompanying this rotation causes the balance weight 45 to revolve. It moves along the radial direction of 41 and balances the weight on the revolution base 41.
[0023]
In the revolving mechanism part having such a configuration, the revolution base 41 is rotated by the rotation of the revolution motor 4, and the container holder 3 held by the holding part 411 of the revolution base 41 causes the rotation shaft 4 a of the revolution motor 4 to be the revolution axis line. Revolves as K.
[0024]
The rotation mechanism unit is composed of a rotation motor 5 and a transmission mechanism that transmits the driving force to the rotation drive gear 3 a of the container holder 3. The rotation motor 5 is provided on the back surface of the frame f and below the revolution motor 4, and the rotation shaft 5 a protrudes from the opening provided in the frame f to the surface side of the frame f. 51 is fitted. A substantially cylindrical rotating pulley 52 is attached to the outer peripheral surface of the base end portion 41a of the revolution base 41 via a pair of ball bearings 42 provided on the inner peripheral surface thereof.
[0025]
The rotation pulley 52 is provided with a V-shaped groove 521 along the circumferential direction of the outer peripheral surface of the base end portion 41 a, and the V-belt 53 is bridged between the V-shaped groove 521 and the pulley 51. The rotation pulley 52 has an inner gear 522 provided on the inner peripheral surface of the tip portion along the circumferential direction, and the rotation driving gear 3 a of the container holder 3 is engaged with the inner gear 522.
[0026]
In the rotation mechanism portion having such a configuration, the rotation of the rotation motor 5 rotates the pulley 51 fitted to the rotation shaft 5 a, and this rotation is transmitted to the rotation pulley 52 via the V belt 53. The rotation pulley 52 rotates concentrically with the revolution base 41 along the outer periphery of the base end portion 41a of the revolution base 41, and the rotation drive gear 3a meshed with an inner gear 522 provided at the tip of the rotation pulley 52 along with this rotation. Are rotated in conjunction with the rotation of the inner gear 522. Then, the container 2 held by the container holder 3 according to the rotation of the rotation driving gear 3a rotates with the rotation driving gear 3a as the rotation axis J in a state where the center axis 2b coincides with the axis of the rotation driving gear 3a. It has become.
[0027]
Here, in this stirring and degassing apparatus 1, the rotation axis J of the container 2 by the rotation mechanism unit and the revolution axis K of the container 2 by the rotation mechanism unit are the floor surface (horizontal plane) on which the mounting plate s is mounted. ) In parallel with each other.
[0028]
Stirring and defoaming of the material to be kneaded by the stirring and defoaming device 1 configured as described above is performed by first storing the container 2 containing the material to be kneaded, which is the object of stirring and defoaming, in the container holder 3 and fixing it (not shown) The container 2 is fixed and held in the container holder 3 by means. Next, the revolution base 41 is rotated by the rotation of the revolution motor 4, and the container 2 in the container holder 3 held by the holding portion 411 of the revolution base 41 is caused to revolve with the rotation axis 4 a of the revolution motor 4 as the revolution axis K. Then, the rotation of the rotation motor 5 is transmitted to the rotation pulley 52 via the V belt 53, the rotation pulley 52 is rotated, the rotation drive gear 3 a is rotated in conjunction with the rotation of the rotation pulley 52, and the container holder 3 is rotated. The held container 2 is rotated with the axis of the rotation drive gear 3a as the rotation axis J.
[0029]
As described above, in the stirring and defoaming device 1, the container 2 held in the container holder 3 revolves with the rotation axis 4 a of the revolution motor 4 as the revolution axis K by the rotation of the revolution motor 4 and the rotation motor 5. Then, the axis of the rotation drive gear 3a of the container holder 3 rotates as the rotation axis J, whereby the material to be kneaded in the container 2 is on the side farther from the revolution axis K of the inner peripheral wall of the container 2 as shown in FIG. Kneaded in a solidified state and stirred and degassed.
[0030]
In this case, since the stirring deaerator 1 is configured with the revolution axis K and the rotation axis J being parallel, the difference between the maximum revolution radius and the minimum revolution radius can be increased, and the change in centrifugal force can be obtained. Can be greatly increased. Therefore, according to the stirring and defoaming apparatus 1, sufficient stirring and defoaming can be performed even when the material to be kneaded has a high viscosity or a small amount. Further, in this stirring and defoaming device 1, the container 2 is revolved and revolved so that the central axis 2b of the container 2 held by the container holder 3 and the rotation axis J coincide with each other. For example, as in the case where the container 2 revolves around two axes, the material to be kneaded does not move vigorously in the container 2, and air can be prevented from being mixed into the material to be kneaded. For this reason, the material to be kneaded can be sufficiently stirred and defoamed.
[0031]
Further, as shown in FIG. 5, the container 2 that rotates around the rotation axis J in the direction of the arrow YA revolves around the revolution axis K in the direction of the arrow YB so that the cylindrical inner wall sequentially passes through the revolution axis K. Since it is configured, a change in centrifugal force can be obtained with a minimum revolution radius as a minimum, and sufficient stirring and defoaming can be performed with stable operation. Furthermore, since the revolution mechanism such as the revolution base 41 can be reduced, the burden on the apparatus is reduced, and the revolution speed can be increased. Therefore, the magnitude and change of the centrifugal force can be further increased to stir and degas a higher viscosity and a small amount of the material to be kneaded.
[0032]
When the material to be kneaded in the container 2 is stirred and defoamed by such stirring and defoaming treatment, the rotation of the revolution motor 4 and the rotation motor 5 is stopped, and the rotation and revolution of the container 2 are stopped. In this case, while the revolution operation of the container 2 is continued, the rotation of the rotation motor 5 is stopped, the rotation operation of the container 2 is finished, and then the rotation of the revolution motor 4 is stopped, and the revolution operation of the container 2 is stopped. By doing so, the apparatus can be stopped while the material to be kneaded is brought close to the outer diameter side of the inner peripheral wall of the container 2. For this reason, the material to be kneaded can be easily taken out from the container 2.
[0033]
Moreover, in this stirring deaerator 1, the rotation axis J and the revolution axis K of the container 2 are configured to be parallel to the floor surface (horizontal plane) on which the mounting plate s is mounted. The opening part of the container 2 attached to the container holder 3 will be in the state opened to the side surface of the stirring deaerator 1. For this reason, it is easy to take out the material to be kneaded that has been defoamed and brought to the inner peripheral wall of the container 2. In addition, the amount of the material to be kneaded stored in the container 2 must be adjusted so that the user does not overflow from the protruding edge 2a of the container 2. Can be prevented. Therefore, by setting the height of the protruding portion 2a of the container 2 so that the material to be kneaded overflows from the protruding portion 2a when a larger amount of the material to be kneaded is stored than the appropriate amount of the material to be mixed, An amount of the material to be kneaded can be stored in the container 2.
[0034]
Since the material to be kneaded that has been sufficiently agitated and degassed in this way has fluidity, it is generally easy to take out the material to be kneaded that has been agitated and degassed without leaving the container 2. Not. However, even in this case, the material to be kneaded adhering to the inner wall of the container 2 can be easily taken out by using the spatula 6 configured as shown in FIG. 6 as the spatula for taking out the material to be kneaded in the container 2. it can.
[0035]
The spatula 6 comprises a gripping part 6a gripped when using the spatula 6 and a scraping part 6b for scraping the material to be kneaded. The scraping part 6b is a cylindrical inner peripheral wall of the container 2. Are formed in a shape corresponding to the shape from the protruding edge portion 2a to the vicinity of the bottom surface. For this reason, the scraping portion 6b inserted into the container 2 is disposed in the container 2 along the inner wall of the container 2, and accordingly, the material to be kneaded adhered to the inner wall and corners of the container 2 is preferably removed. Can do.
[0036]
The stirring and defoaming apparatus of the present invention is not limited to the stirring and defoaming apparatus 1 of the above-described embodiment, and may be changed as appropriate without departing from the gist of the present invention. For example, in the above embodiment, as the container for storing the material to be kneaded, the container 2 simply configured in the shape of a bottomed cylinder is used. However, as shown in FIG. In addition, the container 7 formed in a shape shifted toward the protruding edge portion 7a may be used. By using this container 7, during the stirring and defoaming operation, the position of the bottom surface 7b of the container 7 at the portion where the material to be kneaded adheres with the rotation of the container 7 temporarily changes. 7 is agitated while moving in the directions of arrows YC and YC ′ along the axial direction of No. 7, and a large stirring and defoaming effect can be obtained.
[0037]
Further, as shown in FIG. 8A, the entire container for containing the material to be kneaded is a container 20 formed of an elastic material such as silicon rubber, and the inner wall of the container holder 3 protrudes as an uneven portion. It is good also as a structure which provides the part 3b. According to this configuration, as shown in FIG. 8 (b), in a state where the container 20 is rotating and revolving while being held by the container holder 3, the peripheral wall of the container 20 is deformed by the centrifugal force, and the container 20 It is pressed against the inner peripheral wall of the holder 3 and pressed by the projecting portion 3b, so that the unevenness is formed. Then, as shown in FIG. 8C, the material k to be kneaded positioned on the convex portion 21 of the inner peripheral wall of the container 20 as the container 20 rotates is caused by the centrifugal force accompanying the rotation and revolution of the container 20. Since it is pressed against the inner peripheral wall, it moves so as to avoid the convex portion 21 of the container 20. For this reason, the material k to be kneaded in the container 20 moves in the height direction of the container 20 in the portion where the convex portion 21 of the container 20 is formed. Therefore, according to this configuration, the material k to be kneaded in the container 20 can be sufficiently kneaded, and a large stirring and defoaming effect can be obtained. Then, when the rotation and revolution of the container 20 are stopped, as shown in FIG. 8 (d), the pressure on the inner peripheral wall of the container 20 by the container holder 3 is released, and the inner peripheral wall of the container 20 becomes flat. In the case where the material k to be kneaded is taken out from the container 20 after performing the above, the material k to be kneaded can be easily taken out from the container 20 using a spatula or the like. Moreover, in the state which hold | maintained the container 20 with the container holder 3, since the surrounding wall of the container 20 will be in the state pressed with the protrusion part 3b of the container holder 3, the container 20 is fixed to the container holder 3 and stirring defoaming operation is in progress. Further, the container 20 can be prevented from falling off from the container holder 3. And when inserting a spatula in the container 20 or extracting a spatula from the inside of the container 20, since the protrusion 20a of the container 20 elastically deforms, the to-be-kneaded material k in the container 20 can be taken out easily. .
[0038]
As shown in FIG. 8, one protrusion 3b for forming irregularities on the inner peripheral wall of the container 20 is provided on the bottom surface side and the upper edge side of the inner peripheral wall of the container holder 3 facing each other. However, as shown in FIG. 9, a plurality of protrusions 3 b may be provided on the inner peripheral wall of the container holder 3. Even in this configuration, in a state where the container 20 is rotated and revolved while being held by the container holder 3, as shown in FIG. 9 (b), the peripheral wall of the container 20 is uneven, and the container 20 The material to be kneaded 20 in the container 20 moves in the height direction of the container 20 at the portion where the convex portion 21 of the container 20 is formed, and the material k to be kneaded in the container 20 can be sufficiently kneaded and is large. A stirring defoaming effect can be obtained. When the rotation and revolution movement of the container 20 is stopped, as shown in FIG. 9C, the container holder 3 is released from the pressure on the inner peripheral wall of the container 20, and the inner peripheral wall of the container 20 becomes flat. The kneaded material k can be easily taken out. Moreover, it is not necessary to form the whole container from an elastic material, and only a part may be formed from an elastic material. Furthermore, in the said Example, although the convex part 21 was formed in the surrounding wall of the container 20 in rotation and revolving motion by providing the protrusion part 3b, like the container holder 30 shown in FIG. It is good also as a structure which provides the some groove | channel 3c.
[0039]
Moreover, in the said Example, although provided with the protrusion part 3b in the inner peripheral wall of the container holder 3, it was comprised so that an unevenness | corrugation might be formed in the peripheral wall of the container 20 which rotates and revolves in the state hold | maintained at the container holder 3. For example, it is good also as a structure which replaces with the container holder 3 and provides a protrusion part in the outer peripheral surface of the container 20. FIG. Also with this configuration, since the irregularities are formed on the inner peripheral wall of the container 20 that rotates and revolves while being held by the container holder 3, the material k to be kneaded in the container 20 can be moved in the vertical direction of the container 20. And a large stirring and defoaming effect can be obtained. Further, even when a ring-shaped member or net is interposed between the container holder 3 and the container 20 so as to cover the outer periphery of the container 20, the container 20 that rotates and revolves while being held by the container holder 3. Since unevenness is formed on the inner peripheral wall, the material k to be kneaded in the container 20 can be moved in the vertical direction of the container 20, and a large stirring and defoaming effect can be obtained.
[0040]
Moreover, in the said Example, while the container 2 was formed in the bottomed cylindrical shape, it has the protruding edge part 2a in the opening edge part. However, the cylindrical body may be formed in a shape having openings at both ends and projecting edges at the opening ends on both sides. In the embodiment, the rotation axis J and the revolution axis K of the holding holder 3 for holding the container 2 are configured to be parallel to the floor surface (horizontal plane). However, the rotation axis J and the revolution axis K May be configured such that the rotation axis J and the revolution axis K are perpendicular to the floor surface, for example.

【The invention's effect】
According to the stirring and defoaming apparatus related to the present invention, since the revolution axis and the rotation axis are configured in parallel, the material to be kneaded is pressed against the inner peripheral wall of the container along with the rotation and revolution of the container. Sufficient stirring and defoaming can be performed with a simple configuration in which the revolution axis and the rotation axis are parallel to each other because the centrifugal force applied to the material to be kneaded can be increased. Furthermore, in this stirring and defoaming device, the container is configured so that the central axis of the container held by the holding part and the rotation axis of the holding part coincide with each other so that the container is revolved and rotated. As in the case of revolving around the two axes, the material to be kneaded does not move vigorously in the container, and air can be prevented from being mixed into the material to be kneaded. For this reason, the material to be kneaded can be sufficiently stirred and defoamed.
[0042]
According to the stirring and degassing apparatus related to the present invention, since the revolution axis and the rotation axis are configured in parallel, the material to be kneaded is sufficiently stirred and degassed while being pressed against the inner peripheral wall of the container. . In addition, by allowing the cylindrical inner wall of the rotating container to pass through the revolution axis, the rate of change in centrifugal force due to revolution can be maximized, and the revolution radius of the entire container can also be reduced, reducing the burden on the device. Therefore, the material to be kneaded can be agitated and defoamed optimally.
[0043]
According to the stirring and defoaming apparatus related to the present invention, since the outflow from the container opening portion of the material to be kneaded that adheres to the inner peripheral wall of the rotating and revolving container and is stirred and defoamed can be regulated by the protruding portion, Stirring and defoaming can be performed without providing a lid on the container. Therefore, the material to be kneaded can be easily put into and taken out of the container, the apparatus can be simplified, and the load applied to the apparatus during the stirring and defoaming operation can be reduced.
[0044]
According to the stirring and defoaming device, the container for the material to be kneaded, and the stirring and defoaming method according to the present invention, it is configured such that irregularities are formed on the inner peripheral wall of the container that rotates and revolves while being held by the holding portion. Therefore, the material to be kneaded in the container moves in the height direction of the container so as to avoid the convex portion of the inner peripheral wall of the container, and the material to be kneaded in the container can be sufficiently kneaded to obtain a large stirring and defoaming effect. Can do. In addition, since the elastic portion of the container after the stirring operation is flattened, the material to be kneaded can be easily taken out from the container using a spatula or the like. Furthermore, since the elastic part of the container is held by the holding part while being pressed by the protruding part of the holding part, it is possible to prevent the container from dropping from the holding part during the stirring defoaming operation.
