この発明は、静電塗装用被塗物保持具に関し更
に詳しくは、静電粉体塗装方法により被塗物を塗
装する際に用いる被塗物の保持具に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holder for an object to be coated for electrostatic coating, and more specifically to a holder for an object to be coated used when painting an object by an electrostatic powder coating method. be.
従来、静電塗装をする場合、被塗物保持具に被
塗物を吊るした状態で装塗するが、被塗物の他に
保持具にも塗料が付着する。 Conventionally, when performing electrostatic painting, the object to be coated is suspended from a holder, and the paint adheres not only to the object but also to the holder.
保持具と被塗物に付着する塗料の量は、凡そそ
の表面積に比例した割合となるので、特に小さな
被塗物の場合には保持具に付着する塗料量が多く
なり、塗料の損失が多い。 The amount of paint that adheres to the holder and the object to be coated is roughly proportional to the surface area, so especially in the case of small objects, the amount of paint that adheres to the holder increases, resulting in a large loss of paint. .
保持具に塗料が付着するのを防止するには、保
持具を導電性にし、アースから電気的に絶縁し該
保持具を塗着すべき塗料と同極性の電荷を与えれ
ば、塗料の付着を防止できることが特開昭51−
143048号に開示されている。 To prevent paint from adhering to the holder, make the holder conductive, electrically insulate it from earth, and give it an electric charge of the same polarity as the paint to be applied. Unexamined Japanese Patent Publication No. 1973-1999 shows that it can be prevented.
Disclosed in No. 143048.
しかしながら、この方法では、導電性の保持部
に分布して蓄積されている電荷が、アース物が近
づくと、一気に、短時間でアース物に向けて放電
し、火花放電となる。 However, in this method, when the ground object approaches, the charges distributed and accumulated in the conductive holding part are discharged toward the ground object in a short period of time, resulting in a spark discharge.
着火性の塗料を使用している場合には、この火
花放電が火源となり静電ガンから吐出される塗料
が爆発的に燃え非常に危険な状態となる。 If ignitable paint is used, this spark discharge becomes a fire source, causing the paint discharged from the electrostatic gun to burn explosively, resulting in a very dangerous situation.
この発明の目的は、塗装の際に保持具に塗料が
付着しないようにすることであり、また同時にア
ース物などが近づいても火花放電を生じないよう
な安全な塗装が出来るようにすることである。 The purpose of this invention is to prevent paint from adhering to the holder during painting, and at the same time to enable safe painting without causing spark discharge even if a ground object approaches. be.
この発明は、被塗物支持部と吊下部とを備えた
導電性の被塗物保持具において、該被塗物保持具
の表面の該被塗物支持部と吊下部とを除いた部分
を絶縁物で被覆したことを特徴とする静電塗装用
被塗物保持具である。 This invention provides an electrically conductive workpiece holder equipped with a workpiece support part and a suspension part, in which a portion of the surface of the workpiece holder excluding the workpiece support part and the suspension part is This is an electrostatic coating workpiece holder characterized by being coated with an insulating material.
以下添付図面の実施例につき説明すると、１は
静電物より成る被塗物保持具、２は導電性被塗物
で、保持具１に電気的に接続して装着され保持具
１、コンベヤの吊具４を介して接地Ｇされる。 The embodiments shown in the attached drawings will be described below. Reference numeral 1 denotes an object holder made of an electrostatic material, 2 an electrically conductive object, which is electrically connected to and attached to the holder 1. It is grounded G via the hanger 4.
３は被塗物保持具１の表面の被塗物支持部５と
吊下部６とを除いた部分、即ち、被覆部に設けた
絶縁物で、被塗物２に塗着すべき塗料と同極性の
電荷で塗装前に帯電する。 Reference numeral 3 denotes an insulating material provided on the surface of the workpiece holder 1 excluding the workpiece support part 5 and the hanging part 6, that is, the coating part, which is the same as the paint to be applied to the workpiece 2. Charge with polar charge before painting.
絶縁物３は、保持具１に予め被覆してもよいが
塗料が絶縁性の場合には保持具１に静電塗装をし
ながら保持具表面に絶縁物の被覆を形成してもよ
い。 The insulating material 3 may be coated on the holder 1 in advance, but if the paint is insulating, the insulating material may be coated on the surface of the holder 1 while electrostatically painting the holder 1.
静電塗装すると、荷電された塗料粒子は被塗物
２と保持具１に飛来する。 During electrostatic coating, charged paint particles fly onto the object 2 and the holder 1.
被塗物２は接地電位なので、帯電した塗料粒子
はその表面に付着する。 Since the object 2 to be coated is at ground potential, the charged paint particles adhere to its surface.
一方保持具１の表面に飛来した帯電粒子は、絶
縁物３の表面にある電荷によつて反発され、付着
しない。 On the other hand, the charged particles that fly onto the surface of the holder 1 are repelled by the charges on the surface of the insulator 3 and do not adhere.
従つて、保持具１に付着する塗料の量は大巾に
減少する。 Therefore, the amount of paint adhering to the holder 1 is greatly reduced.
又、保持具１は接地電位に保たれているので塗
装中にその表面電位が高くなることはない。 Furthermore, since the holder 1 is maintained at ground potential, its surface potential will not increase during painting.
この発明は、以上のように構成したので被塗物
を導電性の被塗物支持部で保持し、該被塗物を吊
下部を介して接地し、保持具表面を次工程の静電
塗装と同極性の電荷で帯電せしめ次いで静電塗装
すると塗料は被塗物にのみ付着し、保持具には反
発され付着しない。 Since this invention is configured as described above, the object to be coated is held by the conductive object supporting part, the object to be coated is grounded through the hanging part, and the surface of the holder is coated with electrostatic paint in the next step. When the paint is charged with the same polarity as the paint and then electrostatically applied, the paint adheres only to the object to be coated and is repelled and does not adhere to the holder.
また、保持具は接地され、かつその表面が絶縁
物で被覆されてのるので、塗装中その表面に電荷
がたまつて火花放電することもないので極めて安
全な塗装作業ができる。 Furthermore, since the holder is grounded and its surface is coated with an insulating material, there is no charge buildup on the surface during painting and no spark discharge occurs, allowing extremely safe painting work.
尚、本発明は静電粉体塗装でも溶剤塗料による
静電塗装でもどちらでも使用できることは勿論で
ある。 It goes without saying that the present invention can be used with either electrostatic powder coating or electrostatic coating with solvent paint.
