不良が生じないようにした電着塗装装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electrodeposition coating apparatus. More specifically, the present invention relates to an electrodeposition coating apparatus that prevents coating defects from occurring.
［従来の技術］
従来より電着塗装装置は自動車ボデーなどの塗装に多用
されている。[Prior Art] Electrodeposition coating apparatuses have been widely used for coating automobile bodies and the like.
そのような電着塗装装置は電着浴槽内に可動ハンガーに
装架された自動車ボデーなどの被塗装物を順次入槽させ
、槽内を入槽部から出槽部へ移動させる間に電着塗装さ
せるものである。In such an electrodeposition coating device, objects to be coated, such as automobile bodies, mounted on movable hangers are sequentially placed in an electrodeposition bath, and the electrodeposition is carried out while the objects are moved from the entry section to the exit section of the bath. It is to be painted.

移動方向に沿って多数の隔Ｍ！電極を備えており、その
隔膜電極と自動車ボデーとの間には直流電圧が印加され
ている。かかる印加電圧は電着塗装装置の稼働開始から
稼働終了まで一貫して全ての隔膜電極へ印加されるのが
一般的である。However, such an electro-deposition coating device has a large number of spaces M! in the tank along the direction of movement of the automobile body! The vehicle is equipped with an electrode, and a DC voltage is applied between the diaphragm electrode and the vehicle body. Generally, such applied voltage is consistently applied to all diaphragm electrodes from the start of operation to the end of operation of the electrodeposition coating apparatus.
［発明が解決しようとする問題点］
従来の電着塗装装置において自動車ボデーを塗装するば
あい、塗装ラインの稼働開始時に最初に電着浴槽に入槽
された自動車ボデー（Ｚ）には、第５図に示されるよう
に塗料液に漬けられたときの波模様のような塗膜の凹凸
の筋（Ｈ）（以下、段つき模様という）が表われる。[Problems to be Solved by the Invention] When painting an automobile body using a conventional electro-deposition coating apparatus, the automobile body (Z) that is first placed in the electro-deposition bath at the start of the operation of the coating line has a first coating. As shown in Figure 5, when the paint film is immersed in the paint liquid, uneven lines (H) (hereinafter referred to as a stepped pattern) appear in the paint film, which resembles a wave pattern.
その原因としては、電着浴槽内に他の自動車ボデーが入
槽されていない上記稼働開始時においては、前記最初に
入槽した自動車ボデーに対する電流密度が高くなるので
、部分的に厚い塗膜が析出されやすいことによると考え
られる。The reason for this is that at the start of operation, when no other car bodies are in the electrocoating bath, the current density for the car body that entered the bath first becomes high, resulting in a partially thick coating film. This is thought to be due to the fact that it is easily precipitated.
とくにカチオン電着塗料のばあいには、クーロン収量が
高く少ない電流で塗膜が形成されやすいことからその傾
向が強い。This tendency is particularly strong in the case of cationic electrodeposition paints, since the Coulomb yield is high and a coating film is easily formed with a small current.
また塗装ラインの稼働途中においても、前工程の都合で
、順送りに送られてくる自動車ボデーの一つが抜けるば
あいがあり、その抜けのあとに入槽される自動車ボデー
にも上記と同様の原因によって段つき模様が発生するこ
とがある。Also, during the operation of the painting line, one of the car bodies sent sequentially may fall off due to circumstances in the previous process, and the same cause as above will occur for the car body that enters the tank after it falls off. A stepped pattern may occur.
本発明はかかる事情に鑑み、段つき模様の発生を防止す
ることができる電着塗装装置を提供することを目的とす
る。In view of the above circumstances, it is an object of the present invention to provide an electrodeposition coating apparatus that can prevent the occurrence of stepped patterns.

ている。[Means for Solving the Problems] The electrodeposition coating apparatus of the present invention includes a large number of diaphragm electrodes in an electrodeposition bath, and a movable hanger to sequentially feed objects to be coated into the electrodeposition bath. An electrodeposition coating device whose steady operation state is a state in which the objects to be coated are mounted on all movable hangers at the position where the objects to be coated are placed in the bath, and the objects to be coated are sequentially placed in the tank. It is equipped with a detection means for detecting that a priority object to be coated is not in the tank when an object is placed in the tank, and when the detection means is activated, electricity is supplied to some of the diaphragm electrodes provided near the tank entry section. The structure is characterized in that the diaphragm electrode is cut off and the energization to the diaphragm electrode is restored after a predetermined period of time.
［作 用］
本発明の電着塗装装置によるときは、稼働開始時や稼働
途中において入槽される被塗装物に抜けが生じたばあい
のように、電着浴槽内に入槽される被塗装物の数が定常
運転状態よりも少ないばあいは、そのことが検知手段に
より検知される。[Function] When using the electrocoating apparatus of the present invention, the coating material placed in the electrocoating bath can If the number of objects is less than in the steady operating state, this is detected by the detection means.
その検知手段が作動すると入槽部付近に儀えられた一部
の隔膜電極への通電が遮断されるので、入槽する被塗装

ができる。また順送りに入槽される被塗装物の数が常態
の数になる時間に合わせて前記隔膜電極への通電を回復
させることができるので稼働中を通じて電着浴槽内の電
流密度はほぼ一定に保たれる。When the detection means is activated, electricity is cut off to some of the diaphragm electrodes installed near the tank entry section, so the current density to the objects to be coated entering the tank can be kept at approximately the same level as normal. In addition, the current density in the electrodeposition bath can be kept almost constant throughout the operation because the energization to the diaphragm electrode can be restored in accordance with the time when the number of objects to be coated that are sequentially fed into the bath reaches the normal number. .
