本考案は静電塗装装置に係り、特に回転駆動さ

成る静電塗装装置に関する。[Detailed description of the invention] The present invention relates to an electrostatic coating device, and in particular, applies a high voltage to a cup-shaped body that is driven to rotate, and applies a coating material to the cup-shaped body by centrifugal force and static electricity. The present invention relates to an electrostatic coating device that is equipped with a plurality of electrostatic coating machines that atomize and spray.

毎に夫々防爆対策を施さなければならないという
面倒があつた。 Conventionally, in this type of electrostatic coating equipment, it has been common for each electrostatic coating machine to be directly connected to an electric motor that drives the cup-shaped body. Therefore, it was troublesome that explosion-proof measures had to be taken for each electric motor.
特に、鋼板、アルミニウム板あるいは銅板等の
幅広の板状被塗装物に防錆油等の塗油材を塗布す

に合わせて多数の静電塗装機を配設しなければな
らず、したがつて使用する電動モータの数も多く
その防爆対策に多大の費用と手間を要していた。 In particular, when it comes to electrostatic oil applicators that apply lubricants such as anti-rust oil to wide plate-shaped objects such as steel plates, aluminum plates, or copper plates, a large number of them are installed according to the width of the object to be coated. Therefore, a large number of electric motors are used, and a great deal of cost and effort is required to take explosion-proof measures.

から噴霧される塗布材の噴霧パターンが不均一と
なつて塗布ムラ等の弊害が生じていた。 In addition, in order to eliminate the trouble of such explosion-proof measures, a method has been adopted in which the cup-shaped body is rotationally driven by an air motor, but although this air motor has good stability at high speed rotation, it is unstable at low speed rotation. For example, when the cup-shaped bodies are rotated at a low speed of about 1000 to 1500 rpm, there will be variations in the rotation speed, and the spray pattern of the coating material sprayed from each cup-shaped body will be irregular. The coating was not uniform, causing problems such as uneven coating.

成されたことを特徴とする。 Therefore, the main purpose of the present invention is to solve the above-mentioned troublesome explosion-proof measures and variations in the number of rotations of the cup-shaped body. In an electrostatic coating apparatus in which a plurality of electrostatic coating machines are installed, a chain sprocket is attached to the other end of the rotating shaft of the electrostatic coating machine, and two or more adjacent electrostatic coating machines An endless chain is stretched between the chain sprockets of the machine to form an endless circulation chain mechanism, and a plurality of endless circulation chain mechanisms are connected in series to interlock the cup-shaped bodies of each electrostatic coating machine. It is characterized by being configured to be rotatable.
