特開２０００−２７１４６５号広報JP 2000-271465 A

容器ホルダに装着される混練容器の被混練材料を含む重量に応じて重量バランスを調整する際、従来では、錘の送り量がネジ軸のピッチに支配されるため、ネジ軸の回転操作回数が多くなり、重量バランスの調整に多くの手間を要する問題があった。   When adjusting the weight balance according to the weight including the material to be kneaded of the kneading container mounted on the container holder, conventionally, since the feed amount of the weight is governed by the pitch of the screw shaft, the number of rotation operations of the screw shaft is There has been a problem that a lot of work is required to adjust the weight balance.

本発明は、上述の実状に鑑みて為されたものであって、その主たる課題は、合理的な配置構成により、容器ホルダに装着される混練容器の被混練材料を含む重量に応じた重量バランスの調整作業を迅速・容易に行うことができるとともに、錘の支持構造に公差や誤差等によって錘が可動可能な隙間が発生している場合でも、公転と自転とによる混練時の重量バランスの変動を防止しながらガタツキをも抑制することのできる混練装置を提供する点にある。   The present invention has been made in view of the above-described actual situation, and its main problem is that the weight balance according to the weight including the material to be kneaded of the kneading container attached to the container holder is determined by a rational arrangement configuration. The weight balance during kneading due to revolution and rotation can be adjusted even when there is a gap in the weight support structure that allows the weight to move due to tolerances or errors. It is the point which provides the kneading apparatus which can also suppress backlash while preventing this.

本発明による第１の特徴構成は、公転駆動手段に連動された公転軸芯周りで駆動回転可能な回転体に、混練容器を脱着自在に保持する自転自在な容器ホルダと、この容器ホルダに装着される混練容器の重量に応じて重量バランスを調整する重量バランス調節手段とを設けるとともに、前記容器ホルダを駆動回転させる自転駆動手段を設けてある混練装置であって、
前記重量バランス調節手段には、公転半径方向に移動自在な錘と、この錘に当接した状態での回転操作によって当該錘を公転半径方向に移動させる回転カムと、公転軸芯側から公転半径方向に沿って錘を回転カムのカム面に当接付勢する弾性付勢体とが備えられている点にある。 A first characteristic configuration according to the present invention is a self-rotating container holder that detachably holds a kneading container on a rotating body that can be driven and rotated around a revolution axis linked to a revolution driving means, and the container holder is attached to the container holder. A kneading apparatus provided with a weight balance adjusting means for adjusting a weight balance according to the weight of the kneading container, and provided with a rotation driving means for driving and rotating the container holder,
The weight balance adjusting means includes a weight movable in a revolving radius direction, a rotating cam for moving the weight in a revolving radial direction by a rotating operation in contact with the weight, and a revolving radius from the revolving shaft core side. An elastic urging body that abuts and urges the weight against the cam surface of the rotating cam along the direction is provided.

上記構成によれば、容器ホルダに装着される混練容器の被混練材料を含む重量に応じて重量バランスを調整する際、回転カムの回転操作で錘を公転半径方向に移動させるから、回転カムの１回転以内の回転操作で設定バランス調整範囲の全域での重量バランス調整を行うことができる。   According to the above configuration, when the weight balance is adjusted according to the weight including the material to be kneaded of the kneading container attached to the container holder, the weight is moved in the revolving radius direction by the rotation operation of the rotating cam. The weight balance can be adjusted over the entire range of the set balance adjustment range by a rotation operation within one rotation.

しかも、弾性付勢体によって錘を回転カムのカム面に当接付勢してあるので、回転カムの回転にロスなく的確に錘を移動させることができる。   Moreover, since the weight is urged against the cam surface of the rotating cam by the elastic urging body, the weight can be accurately moved without loss in the rotation of the rotating cam.

さらに、弾性付勢体を設けるにあたっても、公転軸芯側から公転半径方向に沿って錘を回転カムのカム面に当接付勢する状態で設けてあるので、錘の支持構造に公差や誤差等によって錘が可動可能な隙間が発生している場合でも、公転と自転とによる混練時の遠心力で弾性付勢体が圧縮されることを防止することができるとともに、ガタツキをも抑制することができる。   Furthermore, when providing the elastic urging body, since the weight is provided in a state of abutting and urging the cam surface of the rotating cam along the revolving radial direction from the revolving shaft core side, the weight support structure has tolerances and errors. Even when there is a gap in which the weight can move due to, etc., the elastic urging body can be prevented from being compressed by the centrifugal force during kneading due to revolution and rotation, and rattling can also be suppressed. Can do.

したがって、容器ホルダに装着される混練容器の被混練材料を含む重量に応じた重量バランスの調整作業を迅速・容易に行うことができるとともに、錘の支持構造に公差や誤差等によって錘が可動可能な隙間が発生している場合でも、公転と自転とによる混練時の重量バランスの変動を防止しながらガタツキをも抑制することができる。   Therefore, it is possible to quickly and easily adjust the weight balance according to the weight including the material to be kneaded in the kneading container attached to the container holder, and the weight can be moved due to tolerances and errors in the weight support structure. Even when a large gap is generated, rattling can be suppressed while preventing fluctuations in the weight balance during kneading due to revolution and rotation.

本発明による第２の特徴構成は、前記回転カムが、前記錘に形成された凹部内にこれの内側面に公転半径方向から当接した状態で配設されている点にある。   A second characteristic configuration according to the present invention is that the rotating cam is disposed in a recessed portion formed in the weight in a state in which the rotating cam is in contact with the inner surface of the rotating cam from the revolving radial direction.

上記構成によれば、錘に形成された凹部内で回転カムが回転するから、錘の外側に回転カムを配置する場合に比して装置のコンパクト化を図ることができる。   According to the above configuration, since the rotating cam rotates within the recess formed in the weight, the apparatus can be made more compact than when the rotating cam is arranged outside the weight.

本発明による第３の特徴構成は、前記回転体側の取付け部と回転カムとの間には、回転カムを回転方向の複数のバランス調節位置で択一的に係止保持する位置決め手段が設けられている点にある。   According to a third characteristic configuration of the present invention, positioning means for selectively locking and holding the rotating cam at a plurality of balance adjustment positions in the rotating direction is provided between the mounting portion on the rotating body side and the rotating cam. There is in point.

上記構成によれば、剛性の高い回転カムとこれを取付けるための回転体側の取付け部との間のスペースを利用して、回転カムを回転方向の複数のバランス調節位置で択一的に係止保持ための位置決め手段をコンパクトに且つ頑丈に構成することができる。   According to the above configuration, the rotation cam is selectively locked at a plurality of balance adjustment positions in the rotation direction by utilizing the space between the rotation cam having high rigidity and the mounting portion on the rotating body for mounting the rotation cam. The positioning means for holding can be made compact and robust.
