Description

この発明は、床面にオーバースプレー粉の回収溝を設けた、いわゆる底引きタイプと呼ばれる静電粉体塗装ブースに関するものである。   The present invention relates to an electrostatic powder coating booth called a so-called bottoming type in which a recovery groove for overspray powder is provided on a floor surface.

静電粉体塗装は、静電塗装ガンによって粉体塗料を被塗物に吹き付け、静電気によって粉体塗料を被塗物に付着させる塗装方法である。
この静電粉体塗装において、被塗物への粉体塗料の吹き付けは、粉体塗料の飛散を防止するために、通常、塗装ブース内で行われている。そして、被塗物に付着しなかったオーバースプレー粉は、回収精選され、再利用することができるので、静電粉体塗装は、環境に良い塗装として年々注目されている。 Electrostatic powder coating is a coating method in which a powder coating is sprayed onto an object to be coated with an electrostatic coating gun, and the powder coating is adhered to the object by static electricity.
In this electrostatic powder coating, spraying of a powder coating material to an object to be coated is usually performed in a coating booth in order to prevent the powder coating material from scattering. And since the overspray powder which did not adhere to a to-be-coated object can be collect | recovered and selected and can be reused, electrostatic powder coating attracts attention every year as a coating good for an environment.

従来、このオーバースプレー粉の回収を行い易くする静電粉体塗装ブースとして、ブースの床面に、入口からブース出口に向かってオーバースプレー粉の回収溝を設けたものがある。   Conventionally, as an electrostatic powder coating booth for facilitating the recovery of this overspray powder, there has been provided an overspray powder collecting groove on the floor of the booth from the entrance to the booth exit.

ところで、ブースの床面に形成したオーバースプレー粉の回収溝には、オーバースプレー粉を吸引するための排気口が設けられ、この排気口から吸引ダクトを介して集塵機にオーバースプレー粉が吸引されるようになっている。   By the way, an exhaust port for sucking the overspray powder is provided in the recovery groove for the overspray powder formed on the floor of the booth, and the overspray powder is sucked from the exhaust port to the dust collector through the suction duct. It is like that.

ブースの床面の回収溝に設けた排気口周辺部は、吸引風量が他の部分よりも大きくなるため、ブース内の気流に偏りが生じ易い。ブース内の気流に偏りが生じると、ブース内の吸引風速の速い部分、特に、回収溝に近い部分で、被塗物への粉体塗料の付き回りが悪くなり、被塗物にスケが発生しやすくなる。
このため、従来は、回収溝の上面を整流板で覆い、整流板の両側と床面との間の隙間から回収溝内に気流が流れるようにし、ブース内の気流を安定化させ、ブース内の気流に偏りが生じないようにしている。 Since the suction air volume at the exhaust port peripheral portion provided in the collection groove on the floor of the booth is larger than the other portions, the air flow in the booth is likely to be biased. If the air flow in the booth is biased, the powder coating will not adhere to the coating object at the part where the suction air velocity is high, especially the part near the collection groove, and the coating object will become struck. It becomes easy to do.
For this reason, conventionally, the upper surface of the recovery groove is covered with a current plate, and the airflow flows into the recovery groove from the gap between the both sides of the current plate and the floor surface to stabilize the airflow in the booth. The airflow is not biased.

ところが、ブースの長さが長くなると、回収溝の上面を覆う整流板の枚数も多くなるので、色替作業の際には、この多数枚の整流板を持ち上げて、整流板と回収溝内に付着した粉体塗料をエアーブローによって清掃しなければならないので、清掃に手間がかかり、色替え作業に時間が掛かるという問題がある。   However, as the booth length increases, the number of rectifying plates that cover the upper surface of the collection groove increases, so when performing color change work, the large number of rectifying plates are lifted up into the rectifying plate and the collection groove. Since the adhering powder coating must be cleaned by air blow, there is a problem that it takes time for cleaning and takes time for color change work.

そこで、この発明は、可能な限り、整流板の数を減らすことによって、色替え作業時間を短縮しようとするものである。   Therefore, the present invention is intended to shorten the color change work time by reducing the number of current plates as much as possible.

上記の課題を解決するために、この発明は、ブースの床面に、オーバースプレー粉の回収溝をブース入口からブース出口に向かって設け、この回収溝にオーバースプレー粉を吸引する排気口を設けた静電粉体塗装ブースにおいて、上記回収溝の排気口周辺に整流板を設け、排気口周辺部以外の回収溝を開放したのである。   In order to solve the above problems, the present invention provides an overspray powder collecting groove on the floor of the booth from the booth inlet to the booth outlet, and an exhaust port for sucking the overspray powder in the collecting groove. In the electrostatic powder coating booth, a rectifying plate was provided around the exhaust port of the recovery groove, and the recovery groove other than the peripheral portion of the exhaust port was opened.

即ち、この発明者らは、ブースの床面の回収溝の排気口周辺にのみ整流板を設け、排気口周辺部以外の回収溝を開放するようにしても、ブース内の気流に偏りが生じ難く、ブース内の気流を安定化させることができるということを見出したのである。   That is, even if the present inventors provide a baffle plate only around the exhaust outlet of the recovery groove on the floor of the booth and open the recovery groove other than the exhaust outlet peripheral part, the air flow in the booth is biased. It was difficult to find that the airflow in the booth could be stabilized.

この発明によれば、ブースの床面の回収溝を覆う整流板を可能な限り減らすことができるので、色替え作業の際に、回収溝から取り除く整流板の数が減り、またエアーブローする整流板の数も少なくなり、取り除いた整流板を元に戻す作業も減るので、色替え作業時間を大幅に短縮することができる。   According to the present invention, the number of rectifying plates that cover the collection grooves on the floor of the booth can be reduced as much as possible. Therefore, the number of rectifying plates removed from the collection grooves during the color change operation is reduced, and the rectification that blows air is performed. Since the number of plates is reduced and the work of returning the removed current plate is reduced, the color change work time can be greatly shortened.

図１及び図２は、この発明に係る静電粉体塗装ブースの第１の実施形態を示している。
ブース１は、対向する側面２、３、天井面４、床面５、被塗物Ａの入口が設けられる正面６、被塗物Ａの出口が設けられる背面７によって形成されている。 1 and 2 show a first embodiment of an electrostatic powder coating booth according to the present invention.
The booth 1 is formed by opposing side surfaces 2 and 3, a ceiling surface 4, a floor surface 5, a front surface 6 provided with an entrance of the object A to be coated, and a back surface 7 provided with an outlet of the object A to be coated.

天井面４には、ブース１内を被塗物Ａが通過するように、コンベア８を設置している。コンベア８は、レール９と、被塗物Ａを吊るすハンガー１０と、レール９に沿ってハンガー１０を移動させるローラ１１とからなる。   A conveyor 8 is installed on the ceiling surface 4 so that the article A passes through the booth 1. The conveyor 8 includes a rail 9, a hanger 10 that suspends the article A to be coated, and a roller 11 that moves the hanger 10 along the rail 9.

ブース１の側面２、３には、被塗物Ａに粉体塗料を吹き付ける静電塗装ガン１２が、被塗物Ａの両面に対向するように、移動方向の前後にずらせた位置に一対設置され、レシプロケータ１３によって上下動するように設置されている。   On the side surfaces 2 and 3 of the booth 1, a pair of electrostatic coating guns 12 for spraying the powder coating onto the article A to be coated are arranged at positions shifted forward and backward so as to face both sides of the article A. The reciprocator 13 is installed so as to move up and down.

ブース１の床面５は、ホッパー型のダクト形状に形成され、入口側から出口側に向かって回収溝１４が形成されている。ホッパー型の床面の傾斜は、一般に６０度以上にすることが望ましい。   The floor surface 5 of the booth 1 is formed in a hopper type duct shape, and a recovery groove 14 is formed from the inlet side toward the outlet side. In general, the inclination of the hopper type floor surface is desirably 60 degrees or more.

上記回収溝１４の入口側と出口側の端部には、それぞれ集塵機の吸引ダクト１５、１６に接続される排気口１７、１８が形成され、回収溝１４内に流入したオーバースプレー粉が排気口１７、１８から吸引排出されるようになっている。   Exhaust ports 17 and 18 connected to the suction ducts 15 and 16 of the dust collector are formed at the inlet and outlet ends of the recovery groove 14, respectively. Overspray powder that has flowed into the recovery groove 14 is exhausted to the exhaust port. 17 and 18 are sucked and discharged.

上記回収溝１４の上面は、排気口１７、１８を設けた回収溝１４の入口側と出口側の端部周辺のみを整流板１９によって覆い、他の部分は開放している。整流板１９は、ホッパー形状の床面５との間に隙間が空くように設置され、この隙間からの吸引作用により、排気口１７、１８からの急激な吸引を防止することができる。整流板１９の両側には、隙間調整ネジ２０を設けており、この隙間調整ネジ２０によって、床面５と整流板１９の間の隙間を調節することにより、ブース１内の風速を調整することができる。   The upper surface of the recovery groove 14 covers only the vicinity of the inlet and outlet end portions of the recovery groove 14 provided with the exhaust ports 17 and 18 with a rectifying plate 19 and the other portions are open. The rectifying plate 19 is installed so as to have a gap between the hopper-shaped floor surface 5, and abrupt suction from the exhaust ports 17 and 18 can be prevented by the suction action from the gap. A gap adjusting screw 20 is provided on both sides of the rectifying plate 19, and the wind speed in the booth 1 is adjusted by adjusting the gap between the floor surface 5 and the rectifying plate 19 with the gap adjusting screw 20. Can do.

整流板１９の上面形状は、オーバースプレー粉が堆積しないようにするために、中央が高く、両側に向かって傾斜する三角形状に形成されている。   The top surface shape of the current plate 19 is formed in a triangular shape having a high center and inclining toward both sides so that overspray powder does not accumulate.

図１及び図２の実施形態のように、ブース１の回収溝１４の排気口１７、１８の周辺にのみ整流板１９を設け、排気口１７、１８周辺部以外の回収溝１４を開放するようにしても、ブース１内の気流に偏りが生じ難く、ブース１内の気流を安定化させることができるということを、次の実験によって確認した。   As in the embodiment of FIGS. 1 and 2, the rectifying plate 19 is provided only around the exhaust ports 17 and 18 of the recovery groove 14 of the booth 1 so that the recovery grooves 14 other than the peripheral portions of the exhaust ports 17 and 18 are opened. Even so, it was confirmed by the following experiment that the airflow in the booth 1 is less likely to be biased and the airflow in the booth 1 can be stabilized.

実験に使用したブース１は、図１及び図２に示す形状のもので、全長が７０００ｍｍ、排気口１７、１８に２４０ｍ3／ｍｉｎの集塵機を接続した。また、整流板１９は、排気口１７、１８の長さよりも１５０ｍｍ長いものを使用した。 The booth 1 used in the experiment has the shape shown in FIGS. 1 and 2 and has a total length of 7000 mm, and a dust collector with 240 m 3 / min is connected to the exhaust ports 17 and 18. The rectifying plate 19 is longer by 150 mm than the length of the exhaust ports 17 and 18.

そして、ブース１の入口側から出口側に向かって、均等に５分割した位置を測定点にして、ブース１内の風速を計測したところ、５点の測定点での風速は、表１の通りであり、ブース１全体で略均一な風速となり、風速に極端な偏りが生じなかった。   Then, the wind speed in the booth 1 was measured from the entrance side of the booth 1 toward the outlet side, using the positions equally divided into five as measurement points. The wind speeds at the five measurement points are as shown in Table 1. Thus, the wind speed was almost uniform throughout the booth 1, and there was no extreme bias in the wind speed.

この実験で使用したブース１と同じ構造で、図１２及び図１３に示すように、回収溝１４の上面をすべて開放し、整流板１９を使用しない場合のブース１内の５点の風速を測定した結果は、表２の通りであり、排気口１７、１８に近い入口部分と出口部分の風速が速く、中央付近の流速が極端に遅くなり、ブース１全体の風速に極端な偏りが生じることが確認された。   With the same structure as the booth 1 used in this experiment, as shown in FIGS. 12 and 13, the upper surface of the recovery groove 14 is opened, and the wind speed at five points in the booth 1 when the rectifying plate 19 is not used is measured. The results are shown in Table 2. The wind speed near the exhaust ports 17 and 18 is high, the flow velocity near the center is extremely slow, and the wind speed of the entire booth 1 is extremely biased. Was confirmed.

また、この実験で使用したブース１と同じ構造で、図１４に示すように、回収溝１４の上面をすべて整流板１９によって覆った場合のブース１内の５点の風速を同様に測定した結果は、表３の通りであり、ブース１全体で略均一な風速となり、風速に極端な偏りが生じなかった。   In addition, as shown in FIG. 14, the wind speed at five points in the booth 1 in the same structure as the booth 1 used in this experiment and when the upper surface of the collection groove 14 is entirely covered with the rectifying plate 19 is measured in the same manner. As shown in Table 3, the wind speed was almost uniform throughout the booth 1, and no extreme bias was generated in the wind speed.
