ブタンク３に戻るように循環せられている。The electrodeposition paint liquid is constantly supplied from the sub-tank 3 to the tank body 2 by a pump P installed in a paint liquid circulation pipe 4 disposed between the sub-tank 3 and the tank body 2. After being injected from the injection nozzle 6 of the riser pipe 5 disposed in the tank, the liquid is circulated so that it overflows and returns to the sub-tank 3 again.
また、電着槽１のタンク本体２内には、該タンク本体２
内に浸漬された被塗装物７を載置するハンガＨが配設さ
れている。In addition, inside the tank body 2 of the electrodeposition tank 1, the tank body 2
A hanger H is disposed on which the object to be coated 7 immersed is placed.
なお、このハンガＨは通電バー（図示せず）を有し、該
ハンガＨ上に載置された被塗装物７に電気的に接続する
ように成されている。Note that this hanger H has an energizing bar (not shown) and is configured to be electrically connected to the object to be coated 7 placed on the hanger H.
ところで、このように電着槽１のタンク本体２内に配設
されたハンガＨ上に被塗装物７を載置して電着塗装する
電着塗装装置にあっては、被塗装物７を電着槽１の上方
から垂直に降下させてタンク本体２内に浸漬することと
しているから、被塗装物７が電着塗料液中に浸漬される
際に該被塗装物７の下面に気泡が付着発生し易く、特に
被塗装物７の下面に凹凸がある場合には極めて大きな気
泡が付着する。By the way, in the electrodeposition coating apparatus that performs electrodeposition coating by placing the object 7 on the hanger H disposed in the tank body 2 of the electrodeposition tank 1, the object 7 is Since the electrodeposition tank 1 is vertically lowered from above and immersed into the tank body 2, when the object 7 to be coated is immersed in the electrodeposition paint liquid, air bubbles are not formed on the underside of the object 7. Adhesion is likely to occur, and especially when the bottom surface of the object 7 to be coated is uneven, extremely large air bubbles will adhere.
そして、このように被塗装物７の下面に気泡が付着した
状態で電着塗装を行うと、気泡の付着部に電着塗料液が
電着されず塗装ムラを生ずるという弊害がある。If electrodeposition coating is performed with air bubbles attached to the lower surface of the object 7, the electrodeposition coating liquid will not be electrodeposited on the area where the air bubbles are attached, resulting in uneven coating.

プロテクタである。A protector 23 is disposed between adjacent diaphragm electrodes 21 and 21 to prevent the object 7 from coming into contact with the diaphragm electrode 21 .
以上が本発明による電着塗装装置の一例構成であり、次
にその作用について説明する。The above is an example of the structure of the electrodeposition coating apparatus according to the present invention, and the operation thereof will be explained next.
まず、被塗装物７が電着槽１の上方から垂直に降下せら
れて電着塗料液を収容するタンク本体２内に浸漬され、
タンク本体２内に配設されたハンガＨの方形枠体１０上
に載置される。First, the object 7 to be coated is vertically lowered from above the electrodeposition tank 1 and immersed in the tank body 2 containing the electrodeposition paint liquid.
It is placed on a rectangular frame 10 of a hanger H disposed within the tank body 2.
これによって、被塗装物７が方形枠体１０上に配設され
た接触電極１８の天板部１９に接触せられて接地状態と
なり、次いで隔膜電極２１及び底部電極２２に通電する
ことにより、電着塗装が開始される。As a result, the object 7 to be coated comes into contact with the top plate 19 of the contact electrode 18 disposed on the rectangular frame 10 and becomes grounded, and then the diaphragm electrode 21 and the bottom electrode 22 are energized. Painting begins.

図鎖線図示）。At the same time, the hydraulic cylinder 14 is driven and the piston rod 15 is extended or contracted, thereby vertically moving the connecting member 16 fixed to the tip of the piston rod 15, making the connecting member 16 rotatable. By swinging the hanger 1 about the swing shaft 12 via the swing arm member 17 supported by the swing arm member 17, both ends of the rectangular frame 10 of the hanger H on which the object 7 to be coated is placed are alternately moved. Move up and down (second

塗装物７の下面に付着する気泡が浮力によりその傾斜に
沿って上方に移動し、あるいは気泡の一部が該下面の端
縁から離脱する。As a result, both ends of the object 7 placed on the rectangular frame 10 of the hanger H are tilted upward alternately, so that air bubbles adhering to the lower surface of the object 7 are moved along the inclination due to buoyancy. or some of the bubbles detach from the edge of the lower surface.
したがって、被塗装物７を電着槽１のタンク本体２内に
浸漬する際に、該被塗装物７の下面に気泡が付着発生し
たとしても、電着塗装時にその下面に付着する気泡が絶

泡付着による塗装ムラの発生が確実に防止される。Therefore, even if air bubbles adhere to the lower surface of the object to be coated 7 when the object to be coated 7 is immersed in the tank body 2 of the electrodeposition tank 1, the air bubbles that adhere to the lower surface of the object 7 during electrocoating are constantly generated. Since it is moved or removed from the lower surface, uneven coating due to bubble adhesion is reliably prevented.
そして、電着塗装が終了すると、油圧シリンダ１４の駆
動を停止させてハンガＨの揺動を停止し、被塗装物７を
タンク本体２外に搬出する。When the electrodeposition coating is completed, the drive of the hydraulic cylinder 14 is stopped, the swinging of the hanger H is stopped, and the object to be coated 7 is carried out of the tank body 2.
なお、上述の実施例においては、ハンガＨを揺動させる
駆動源として油圧シリンダ１４を適用した場合について
説明したが、本発明はこれに限るものではなく例えば揺
動軸１２をモータその他の駆動源によって回動させるも
のであっても良い。In addition, in the above-mentioned embodiment, the case was explained in which the hydraulic cylinder 14 was applied as the drive source for swinging the hanger H, but the present invention is not limited to this. It may be rotated by.
また、油圧シリンダ１４は例えば接触電極１８と連動す
るように構成して、接触電極１日が被塗装物７に接触し
ている間において作動するようにしても良い。Further, the hydraulic cylinder 14 may be configured to operate in conjunction with the contact electrode 18, for example, so that it operates while the contact electrode is in contact with the object 7 to be coated.
更に、ハンガＨは、電着塗装を行っている間、常に揺動
させる必要はなく、１回又は適宜な間隔をもって間欠的
に数回だけ行うものであっても良い。Further, the hanger H does not need to be constantly oscillated during electrodeposition coating, and may be oscillated only once or several times intermittently at appropriate intervals.
以上述べたように、本発明によれば、電着槽内に浸漬さ
れた被塗装物を載置するハンガの両端が交互に上下動す

気泡を容易に移動させ、あるいは除去することができ、
したがって気泡の付着による塗装ムラを防止して均一な
電着塗装を行うことができるという優れた効果がある。As described above, according to the present invention, both ends of the hanger on which the object to be coated immersed in the electrocoating tank is placed are moved up and down alternately, so that the lower surface of the object to be coated is Adhering air bubbles can be easily moved or removed,
Therefore, it has the excellent effect of preventing uneven coating due to the adhesion of air bubbles and enabling uniform electrodeposition coating.
