Abstract
Description
本発明は回転塗装装置の被塗装物を保持する保持軸に関する。 The present invention relates to a holding shaft for holding an object to be coated of a rotary coating apparatus.
従来の回転塗装装置に付いて図4により説明すると、回転塗装装置1は固定されたベース2と、このベース2に連結され、ベース2に対して垂直な第1軸J1を中心に
ベース2に対して旋回する第1アーム3と、第1アーム3の先端に連結され、第1軸J1に対して平行な第2軸J2を中心に第1アーム3に対して旋回するL字型の第2アーム4と、第2アーム4の先端に連結され、第2軸J2に対して垂直な第3軸J3を中心に第2アーム4に対して旋回する第3アーム5を備え、この第3アーム5の先端および基部に夫々第1保持部6および第2保持部7を設け、この第1保持部6および第2保持部7は夫々第4軸J4と第3軸J3を中心に鎖線で示す被塗装物W1、W2を回転させ、鎖線で示すスプレーガン8により被塗装物W1、W2に塗料を吹付けるようにしている。
The conventional rotary coating apparatus will be described with reference to FIG. 4. The
次に第1保持部6について図5により説明をする。説明に当たり第2保持部7は第1保持部6と同一構成であるので説明は省く。
第3アーム5内のプーリ、タイミングベルト(図示してない)により第1保持部6の回転軸9は第4軸J4を中心に回転し、回転軸9に挿入された被塗装物W1を取付けた保持軸10は回転軸9の第4軸J4に対して直角方向に設けたピン11に保持軸10の一端に設けた溝12を挿入させて保持軸10を回転させている。
Next, the
The rotating
従って、保持軸10の一端に設けた溝12はピン11の径より僅かに幅広で、底部は溝幅と同一径の半円面と成っている。また回転軸9に挿入された保持軸10の外径も回転軸9の内径より僅かに小径となっていて、天地方向の場合は問題ないが、被塗装物W1によっては任意の角度に傾けて使用する場合には、図6に示すような鎖線で示す保持軸10aとなり、第4軸J4を中心に保持軸10が回転した場合、遠心力により回転軸9から脱落することがあるという欠点があった。
Accordingly, the groove 12 provided at one end of the
本発明の目的は前述のように任意の角度に傾けて使用する場合に保持軸10は回転軸9から脱落することがあるという欠点を解消し、安定した塗装が可能な回転塗装装置の被塗装物を保持する保持軸を提供することにある。
The object of the present invention is to eliminate the drawback that the
そのためには、保持軸が任意の角度に傾向いても回転軸から脱落しないようにすることであり、保持軸の一端に設けた溝は底部が入り口の溝幅より大径の円筒面とすれば回転軸が傾いてもピンが円筒部に引っ掛かり溝より脱落することがないという結論に達し、本発明に至った。 For that purpose, even if the holding shaft tends to be at an arbitrary angle, it should be prevented from falling off the rotating shaft, and the groove provided at one end of the holding shaft should be a cylindrical surface whose bottom is larger in diameter than the groove width of the entrance. The conclusion was reached that the pin does not get caught in the cylindrical part and fall off from the groove even if the rotation axis is inclined, and the present invention has been reached.
前述の目的を達成するため本発明は被塗装物を保持するとともに回転させて、塗料を吹付けるスプレーガンに対峙させる回転塗装装置の保持部の保持軸において、回転塗装装置の回転軸に挿入される保持軸端部に回転軸に対し直角方向に設けた回転伝達用ピンの径より僅かに幅広で、底部はピン径より大径の円筒面である溝を設けたことを特徴とする回転塗装装置の保持部の保持軸とした。 In order to achieve the above-mentioned object, the present invention is inserted into the rotating shaft of the rotary coating device in the holding shaft of the holding portion of the rotary coating device that holds and rotates the object to be opposed to the spray gun that sprays the paint. Rotating coating, characterized in that the holding shaft end is provided with a groove that is a cylindrical surface that is slightly wider than the diameter of the rotation transmitting pin provided in a direction perpendicular to the rotating shaft and whose bottom is larger than the pin diameter. A holding shaft of the holding unit of the apparatus was used.
またこの保持部の保持軸を有する、被塗装物に塗料を吹付けるようになした回転塗装装置とした。 Moreover, it was set as the rotation coating apparatus which has a holding shaft of this holding part and was made to spray a coating material on a to-be-coated object.
さらにこの保持部の保持軸を有し、固定されたベースと、このベースに連結され
、ベースに対して垂直な第1軸J1を中心にベースに対して旋回する第1アームと、第1アームの先端に連結され、第1軸J1に対して平行な第2軸J2を中心に第1アームに対して旋回するL字型の第2アームと、第2アームの先端に連結され、第2軸J2に対して垂直な第3軸J3を中心に第2アームに対して旋回する第3アームを備え、この第3アームの先端および基部に夫々第1保持部および第2保持部を設け、この第1保持部および第2保持部先端に夫々取付けた被塗装物W1、W2を第4軸J4と第3軸J3を中心に回転させ、被塗装物W1、W2に塗料を吹付けるようにした回転塗装装置とした。
Further, the holding unit has a holding shaft, a fixed base, a first arm connected to the base and pivoting about the first axis J1 perpendicular to the base, and a first arm An L-shaped second arm that pivots about a second axis J2 parallel to the first axis J1 and pivots about the first arm; and a second arm that is coupled to the tip of the second arm; A third arm that pivots with respect to the second arm about a third axis J3 perpendicular to the axis J2, and a first holding portion and a second holding portion are provided at the tip and the base of the third arm, respectively. The objects W1 and W2 attached to the tips of the first holding part and the second holding part are rotated about the fourth axis J4 and the third axis J3 so that the paint is sprayed on the objects W1 and W2. Rotating coating equipment.
この発明によれば、回転軸が傾いてもピンがピン径より大径の円筒部に引っ掛かり溝より脱落することがない。
According to this invention, even if the rotating shaft is tilted, the pin is caught in the cylindrical portion having a diameter larger than the pin diameter and does not fall off from the groove.
次に本発明の1実施形態を図1ないし図3により説明すると、説明に際し、回転塗
装装置は前述の従来装置と同一構成となっておりその詳細な構成および作用は省略し
、本発明により新たに変わった部材のみ説明する。
この実施形態は第2軸J2を中心に第2アームおよび第3アーム5を鎖線で示すよう
に傾けて、被塗装物W1a、W2aにスプレーガン8から塗料を吹付ける例を示し、その保持部6は図2(イ)、(ロ)、(ハ)に示すように被塗装物W1を取り付ける保持軸20の反被塗装物W1側の端部は回転軸に対し直角方向に設けた回転伝達用ピン径d0より僅かに幅広d1の溝21aと、底部はピン径d0より大径d2の円筒面21bからなる溝21を設けてある。
Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3. In the description, the rotary coating apparatus has the same configuration as the above-described conventional apparatus, and its detailed configuration and operation are omitted. Only the newly changed members will be described.
This embodiment shows an example in which the second arm and the
前述のように構成したので回転軸が傾いても、図3に示すように鎖線で示す保持軸20のようにピン11がピン径より大径の円筒面21cに引っ掛かり溝21より脱落することがない。
ここで前述の説明では保持軸端部に設けた溝の底部は円筒面としたが、勿論これに限ったものではなく三角等の多角面でも良い。
Since it is configured as described above, even if the rotation axis is tilted, the
Here, in the above description, the bottom of the groove provided at the end of the holding shaft is a cylindrical surface, but of course it is not limited to this and may be a polygonal surface such as a triangle.
