また、ドロップドア保持機構とドロップドアとの間の摩擦を低減して磨耗を抑えるとともに、混練室とドロップドアとの密閉性を維持することができる混練機を提供することを目的とする。
本発明の一態様の混練機(以下本発明の混練機と称する)は、ゴムが投入されるチャンバーと、前記チャンバー内に配されて、回転することで、前記チャンバー内に投入された前記ゴムを混練する混練用ロータと、前記チャンバーの下部を閉塞するとともに、前記チャンバーに回転可能に取り付けられて下方に回転することで、前記チャンバーの前記下部を開放可能に構成されたドロップドアと、複数のリンク部材が互いに回転可能に連結して構成され、一のリンク部材の一端部が前記チャンバーの下面に回転可能に設けられるとともに、前記一のリンク部材の前記一端部の回転に応じて、前記一のリンク部材の他端部に設けられた当接面が、前記ドロップドアに設けられた被当接面に対し略垂直な方向に移動して前記被当接面に当接することが可能に設けられたリンク機構と、前記リンク機構を回転させる可動部と、を備えることを特徴とする。
このように構成することで、リンク機構によりドロップドアの保持力が増幅されるため、ドロップドア保持機構のドロップドアに対する押付力を低減することができる。そのため、ドロップドア保持機構を小型化することができる。さらに、混練機を小型化することができ、省スペース化につながる上、混練機のメンテナンス性が向上するとともに混練機を製造するためのコストも低減することができる。
このように構成することで、ドロップドア保持機構をドロップドアに対して垂直方向に押し付けるため、ドロップドア保持機構とドロップドアとの間の摩擦が低減して磨耗を抑えることができる。そのため、混練室とドロップドアとの密閉性を維持することができるとともに、ドロップドア保持機構およびドロップドアの寿命を長くすることができる。
また、ドロップドアが磨耗してもリンク機構が働くため、ドロップドア保持機構とドロップドアとの間のシール性が低下せず、ドロップドアを保持することができる。
このように構成することで、混練室3内で混練された材料が混練室3外に取り出される際に、ドロップドア保持機構13を退避させることができる。そのため、混練された材料がドロップドア保持機構13に付着することがない。
このように構成することで、リンク機構によりドロップドアの保持力が増幅されるため、ドロップドア保持機構のドロップドアに対する押付力を低減することができ、ドロップドア保持機構を小型化することができる。
このように構成することで、リンク機構によりドロップドアの保持力が増幅されるため、ドロップドア保持機構のドロップドアに対する押付力を低減することができ、ドロップドア保持機構をより小型化することができる。
また、本発明の混練機によれば、ドロップドア保持機構をドロップドアに対して垂直方向に押し付けるため、ドロップドア保持機構とドロップドアとの間の摩擦が低減して磨耗を抑えることができる。そのため、混練室とドロップドアとの密閉性を維持することができる。
図1は、本実施形態に係る混練機1の概略構成を示す構成図である。
図1に示すように、混練機1は、チャンバー2と、チャンバー2の内部に設けられた混練室3と、混練室3の内部に配置された一対の混練用ロータ4、5とを備える密閉式の混練機である。なお、一対の混練用ロータ4、5は、同一若しくは類似した構成を備えている。
図2及び図3に示すように、ドロップドア12は、回転中心軸24を中心として、回転可能に設けられている。
ドロップドア12には、被当接面18が形成されている。被当接面18は、被当接面18における回転中心軸24回りの接線L1に対して、被当接面18の法線L2が外周側に向かうように傾斜して設けられている。すなわち、被当接面は18は下側を向いた面であり、回転中心軸24を中心として、外側から中心側(図3の紙面においては、右側から左側)に進むに従い、下方に傾斜している傾斜面である。
なお、当該ストッパ26は、第三のリンク部材16の一端部16aに、第二のリンク部材15の他端部15aに向かって突出するように形成されてもよい。
図8は、本実施形態に係る混練機101のドロップドア保持機構113の概略構成を示す構成図である。また、図9は、本実施形態に係る混練機101のドロップドア保持機構113の一部分を拡大して示す部分拡大図である。
図8に示すように、ドロップドア保持機構113は、第一のリンク部材114、第二のリンク部材115、及び第三のリンク部材116を備える。
図9に示すように、第一のリンク部材114の一端部114aは、チャンバー2の下面に、第一の可動部119を介して回転可能に設けられている。第一のリンク部材114の他端部114bと第二のリンク部材115の一端部115aとは、第二の可動部120を介して互いに回転可能に連結されている。第二のリンク部材115の他端部115bと第三のリンク部材116の一端部116aとは、第三の可動部121を介して互いに回転可能に連結されている。なお、本実施形態では、第三のリンク部材116の他端部116bは、チャンバー2の下面に第四の可動部122を介して回転可能に設けられている。
第一のリンク部材114の他端部114bには、ドロップドア12に設けられた被当接面18と当接する当接面117が設けられている。
第二の可動部120は、油圧シリンダ23のシリンダロッド22と連結されている。
しかしながら、本発明はこれに限定されるものではなく、油圧シリンダ23の代わりに、例えば、空圧シリンダ、電動シリンダ等を採用してもよい。
