り、よつて常に爆発、環境汚染のおそれが懸念さ
れた。 This is because when applying by spraying, a large amount of gas containing an organic solvent (acetone) is generated, and the equipment required to collect and process it becomes large. Additionally, it is technically extremely difficult to completely seal the system to prevent acetone gas, which is flammable and dangerous or harmful to the human body, from leaking out of the system, and there is therefore always a risk of explosion or environmental pollution. was a concern.

続しがたい欠点があつた。 On the other hand, when spraying with an airless gun, the nozzle diameter must be extremely small to ensure uniformity of the coating, which prevents the viscous liquid from drying and hardening, increasing viscosity, or contaminating dust and foreign matter. The drawbacks were that they were easily clogged, difficult to maintain, and difficult to maintain stable operation.
（考案の目的）
そこで、この考案の目的は、構造が簡単で、か

を設置した構成とされている。(Structure of the invention) In order to achieve the above object, the viscous liquid continuous coating device of this invention applies viscous liquid such as adhesive to an object to be coated such as a long pipe that passes through a nearly sealed application chamber. A large amount of liquid is sprayed as a jet using a thick application nozzle. Then, at a position on the forward direction side of the object to be coated than the position of the coating nozzle, a scraper is used to scrape off the viscous liquid applied to the surface of the object to be coated in an appropriate state to form a thin and uniform coating film. A mechanism was set up. A blow-leveling mechanism was installed at a position further in the advancing direction of the object to be coated than the position of the scraping mechanism, which further spreads the viscous liquid scraped off by the scraping mechanism to form a uniform coating film. Furthermore, an air seal mechanism is installed at the entrance and exit of the coating chamber of the object to be coated to prevent the gas containing the organic solvent from leaking out of the coating chamber.
（作用効果）
つまり、粘性液体は、孔詰りの心配がない程度
の太い塗布ノズルを通じて流れ出るに任せた噴流
として吹付け塗布するから、ノズルの詰りは起ら
ない。(Effects) In other words, the viscous liquid is sprayed as a jet flow through a coating nozzle that is so thick that there is no fear of clogging the hole, so no clogging of the nozzle occurs.
また、前記塗布ノズルで塗布する結果、塗布室
内は、常時有機溶剤を含むガス濃度が飽和状態で
運転される。このため、乾燥は起らず、粘性液体

処理装置の必要がないので、装置を単純にかつ小
形化でき、占有スペースの縮小化を図ることがで
きる。その上、安定運転を維持しやすく、コスト
ダウンが図れる。 Moreover, as a result of coating with the coating nozzle, the interior of the coating chamber is always operated in a state where the concentration of the gas containing the organic solvent is saturated. Therefore, no drying occurs, and no accumulation or adhesion of viscous liquid occurs. Therefore, maintenance is easy. Moreover, there is little gas generation, and gas recovery and
Since there is no need for a processing device, the device can be made simple and compact, and the space it occupies can be reduced. Moreover, stable operation can be easily maintained and costs can be reduced.
一方、粘性液体は塗布ノズルで大量に塗布した
あと、かき落し機構及び吹き均し機構により所望
の薄く均一な塗膜を形成するので、安定運転を維
持しやすい。 On the other hand, after a large amount of viscous liquid is applied with a coating nozzle, a desired thin and uniform coating film is formed by a scraping mechanism and a blow-leveling mechanism, making it easy to maintain stable operation.

スを生じないのである。 In addition, the entrance and exit portions of the object to be coated, where gas easily leaks and is difficult to completely seal, are sealed with a so-called air curtain by an air seal mechanism, so that gas leakage to the outside is minimal. Therefore, it is highly safe, maintains good environmental hygiene, and does not cause loss of viscous liquid.

のである。 In the figure, 8 and 8' indicate a scraping mechanism A at a position on the forward side of the pipe 2, which is relatively close to the coating nozzle 3.
There are two upper and lower scraping plates that make up the pipe 2, and they are installed approximately at right angles to the axis of the pipe 2.
As shown in Fig. 2, the scraping plates 8, 8' are semicircular (however, the scraping plates 8, 8' are semicircular with a diameter 1 mm to 2 mm larger than the outer diameter (about φ30) of the pipe 2 (although it may be approximately the same diameter). A similar recess 8 having a cross-sectional shape (according to the cross-sectional shape of)

循環ポンプ１２とは冷却器１３を介して接続され
ている。 Reference numeral 11 in FIG. 1 denotes a leveling air nozzle constituting the leveling mechanism B at a position closer to the forward direction of the pipe 2 than the position of the scraping mechanism A, and is installed in the coating chamber 1. The blow-leveling mechanism B prevents the viscous liquid 5 sprayed onto the surface of the pipe 2 by the application nozzle 3 from being applied to the upper and lower halves of the pipe 2 even after being scraped off by the scraping mechanism A. Considering that the amount tends to be uneven, the excess amount of viscous liquid 5 is blown off and the viscous liquid 5 adhering to the pipe 2 is spread thinly and uniformly over the entire circumference to obtain the desired amount. It is used to form a coating film. Therefore, the leveling air nozzle 11
is approximately relative to the moving direction of pipe 2 (arrow direction)
It has an acute angle of inclination of about 30°, and the pipe 2
It is formed as an annular body concentrically surrounding the entire circumference of the
It is connected to the circulation pump 12 via a cooler 13.
つまり、循環ポンプ１２で圧縮し昇温した空気

やし吹き均しエアノズル１１からエアカーテン状
に吹き出させるのである。 In other words, air that has been compressed and heated by the circulation pump 12 is cooled to about room temperature by passing through the cooler 13 and then blown out from the air nozzle 11 in the form of an air curtain.
なお、塗布室１の上部には吸気口１４を設け、
該吸気口１４と循環ポンプ１２の吸込口とがフイ
ルタ１５を介して接続されている。つまり、循環
ポンプ１２による空気の流れは閉循環する。 Note that an intake port 14 is provided at the top of the coating chamber 1,
The suction port 14 and the suction port of the circulation pump 12 are connected via a filter 15. In other words, the air flow caused by the circulation pump 12 is circulated in a closed manner.
従つて、塗布室１内の気圧は、循環ポンプ１２

そして、空気中の有機溶剤を含むガスはフイルタ

した運転を維持できるのである。 Therefore, the atmospheric pressure inside the coating chamber 1 is reduced by the circulation pump 12.
A good balance is maintained between the suction pressure and discharge pressure.
Since the gas containing the organic solvent in the air passes through the filter 15, it does not have any adverse effect on the circulation pump 12. In addition, since the concentration of the gas containing the organic solvent is always kept in a saturated state due to the closed circulation of air, adhesion, accumulation, or nozzle clogging due to drying of the viscous liquid 5 in the coating chamber 1 does not occur, and the coating is stable. It is possible to maintain operation.

と接続されている。 Next, reference numerals 16 and 17 in the figure are air blowing nozzles that constitute an air seal mechanism C at the inlet and outlet portions of the pipe 2 to the coating chamber 1. The air blowing nozzles 16 and 17 are formed as annular bodies extending substantially perpendicularly to the pipe 2 and surrounding the entire circumference thereof, and each of the air blowing nozzles 16 and 17 is formed as an annular body extending approximately at right angles to the pipe 2 and surrounding the entire circumference thereof.

従つて、エアー吹出しノズル１７，１８から吹

An example of the provided configuration is shown. In this way, the viscous liquid 5 flows through the pipe 2 through the V-shaped notch 8b...
A large amount of it adheres to the surface in convex stripes. Therefore, it is more convenient to form a uniform coating film if it is stretched and leveled.
