【発明の詳細な説明】
本発明は、被塗物に部分的及び所望の形状に粉体塗料を
焼付けることができるプリント式静電塗装法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing-type electrostatic coating method that allows a powder coating to be baked partially and into a desired shape on an object to be coated.
従来の粉体塗料の塗装法として、流動浸漬法、静電吹付
法、静電流動浸漬法などがある。Conventional powder coating methods include fluidized dipping, electrostatic spraying, and electrostatic dynamic dipping.
これらはいずれも、被塗物全体を粉体塗装するのに適し
た方法であり、部分塗装が必要な場合は、塗装しない部
分にマスクをして上述の方法により塗装を行なうのが一
般的であった。All of these methods are suitable for powder coating the entire object to be coated, but if partial coating is required, it is common to mask the areas that will not be coated and apply the coating using the method described above. there were.
そのため、部分塗装にはマスキングに伴う手間と時間が
かなりかかるので、塗装能率が低かった。For this reason, partial painting requires considerable time and effort associated with masking, resulting in low painting efficiency.
昔た、マスキングが不充分なため、不良の塗装品が発生
することも少なくなかった。In the past, insufficient masking often resulted in defective painted products.
そこで、粉体塗装の場合においても、印刷のように部分
的及び所望の形状に粉体塗装を行なえるように創作した
のが本発明による塗装法である。Therefore, even in the case of powder coating, the coating method according to the present invention has been created so that powder coating can be applied locally and in a desired shape like printing.
本発明の構或を図面を参考に発明する。The structure of the present invention will be invented with reference to the drawings.
フィーダー４から供給された粉体塗料の粒子は、電極板
５に当って帯電し、アースされた型版へ電気力線に沿っ
て飛行し、型版の表面に付着する。Powder paint particles supplied from the feeder 4 are charged when they hit the electrode plate 5, fly toward the grounded mold plate along the lines of electric force, and adhere to the surface of the mold plate.
ここ筐では、静電塗装法による従来技術である。Here at Kagome, the conventional technology is electrostatic painting.
粉体塗料が付着したものが被塗物であり、そのま１焼付
け工程を行なえば、従来の粉体塗料による全体塗装がで
きあがる。The object to be coated is the one to which the powder coating is applied, and if a single baking process is performed, the entire surface is coated with the conventional powder coating.
ところが、本発明においては、所望の部分又は形状に被
塗物を塗装するために、焼付け前に所望の部分又は形状
に象った型版に粉体塗料を付着させることに特徴を有す
る。However, the present invention is characterized in that, in order to coat a desired part or shape of an object, a powder coating is applied to a template shaped in the desired part or shape before baking.
特許請求の範囲第２項記載の型版１は、粉体塗装をする
所望の形状に基板に凹凸を穿設したものであり、凸部に
焼付けされる粉体塗料が付着することになる。The mold plate 1 described in claim 2 has a substrate having concavities and convexities formed in a desired shape for powder coating, and the powder coating to be baked will adhere to the convexities.
次に型版１の凸部に付着した粉体塗料の表面に、粉体塗
料が溶融する温度に加熱された被塗物６が押圧されると
、被塗物６に型版１の凸部の形状通りに粉体塗料の塗膜
が融着する。Next, when the object 6 to be coated, which has been heated to a temperature at which the powder coating melts, is pressed against the surface of the powder coating adhered to the convex portions of the mold plate 1, the convex portions of the mold plate 1 The powder coating film is fused according to the shape.
したがって、型版１の凸部を所望の形状に象れば、被塗
物６に所望の形状に粉体塗料をプリント式に塗装するこ
とができる。Therefore, if the convex portions of the template 1 are shaped into a desired shape, the object to be coated 6 can be coated with the powder coating in the desired shape in a printing manner.
特許請求の範囲第３項記載の型版２は、焼付けされる粉
体塗料が付着する型版２の表面部分以外の部分を穿孔し
たものである。The mold plate 2 described in claim 3 has holes formed in a portion other than the surface portion of the mold plate 2 to which the powder coating to be baked adheres.
特許請求の範囲第２項記載の型版１の場合、型版１の凸
部に付着しなかった粉体塗料は凹部に溜筐るため、不要
の塗料を回収する操作が必要である。In the case of the mold plate 1 described in claim 2, since the powder paint that has not adhered to the convex portions of the mold plate 1 is collected in the recesses, an operation is required to collect unnecessary paint.
そこで、本項記載の型版２では、焼付けされる型版２の
表面に付着しなかった塗料は、孔隙部７から下に落下す
るので、回収管８により不要の粉体塗料を容易に回収す
ることができる。Therefore, in the mold plate 2 described in this section, since the paint that does not adhere to the surface of the mold plate 2 to be baked falls down through the hole 7, unnecessary powder paint can be easily collected by the collection pipe 8. can do.
特許請求の範囲第４項記載の型版３は印刷における輪転
機のように回転円筒形としたものであり、同一形状の塗
装を連続的に行えるようにしたものである。The mold plate 3 described in claim 4 has a rotating cylindrical shape like a rotary press in printing, and is designed to enable continuous painting of the same shape.
ノズル９から噴射された帯電した粉体塗料の粒子は、ア
ースされた型版３上に付着する。The charged powder coating particles sprayed from the nozzle 9 adhere to the grounded mold plate 3.
この型版３を回転させて加熱した被塗物６に押圧すると
、型版３の凸部に付着した粉体塗料は被塗物６にプリン
ト式に融着する。When this template 3 is rotated and pressed against a heated object 6, the powder coating material adhering to the convex portions of the template 3 is fused to the object 6 in a printed manner.
上述したように、本方法は、従来実施が困難であった粉
体塗料の部分塗装及び所望の形状の塗装を可能としたも
のである。As described above, the present method enables partial coating and coating of a desired shape with powder coating, which has been difficult to implement in the past.
型版を用いて、その型版に粉体塗料を付着させた後、加
熱した被塗物に押圧する操作以外は従来技術であるため
、実施にさほどの困難は伴わない。Since the process is conventional technology except for applying the powder coating to the template using a template and then pressing it onto the heated object, the process is not very difficult to implement.
色毎に上述した方法で塗装すれば、複数の配色を施した
被塗物が得られる。If each color is coated using the method described above, a coated object with a plurality of color schemes can be obtained.
本方法によれば、粉体塗装の従来にも増して幅広い用途
を提供することができるものである。According to this method, it is possible to provide a wider range of applications than ever before for powder coating.
