Description

[Detailed explanation of the idea]

【０００１】0001

[Industrial application field]

本考案は、塗装乾燥装置、特にシンナ系の溶剤を含有する塗料で塗装した塗装品の塗装乾燥装置に関する。 This invention uses a paint drying device, especially for paints painted with paints containing thinner-based solvents. Regarding paint drying equipment for products.

【０００２】0002

[Conventional technology]

シンナ系の溶剤を含有する塗料で塗装した塗装品の乾燥は、自然乾燥による方法又は強制乾燥による方法が採用される。 Painted items painted with paints containing thinner-based solvents should be dried naturally. A method using drying method or forced drying is adopted.

【０００３】0003

[Problem that the idea aims to solve]

然し乍ら、自然乾燥によるものは、指で触れて跡が付かなくなるまでに約１５分以上かかるものが一般的であり、塗装後早々に梱包作業する等の次工程の作業ができず、塗装後の作業性が損なわれている。また、ハンガーに吊り下げて置くことで、多くのスペースが必要になる。 However, if you dry it naturally, it will take about 15 minutes to leave a mark when you touch it with your finger. In general, it takes more than a minute, and the next process such as packing immediately after painting. workability after painting is impaired. You can also hang it on a hanger. This requires a lot of space.

【０００４】一方、オーブン等の加熱強制乾燥によるものは、火災の危険性がある。本考案は上記に鑑みてなされたもので、乾燥の時間の短縮化が図れ、火災の危険性を回避し、しかも自動化が図れる塗装乾燥装置を提供することを目的とする。0004 On the other hand, there is a risk of fire when using forced drying methods such as an oven. This invention was developed in view of the above, and it can shorten the drying time and reduce the risk of fire. The purpose is to provide a paint drying device that avoids risks and can be automated. .

[Means to solve the problem]

本考案は、シンナ系の溶剤を含有する塗料で塗装した塗装品の塗装乾燥装置において、上記塗装品を収納した開閉ドアを有する容器にパイプを介して減圧ポンプを連結し、減圧ポンプに制御手段を接続したことを特徴とする。 This invention is suitable for use in paint drying equipment for painted products painted with paints containing thinner-based solvents. Then, a vacuum pump is connected via a pipe to a container with an opening/closing door containing the above-mentioned painted product. The pump is characterized in that a control means is connected to the decompression pump.

【０００６】[0006]

[Effect]

シンナ系の溶剤を含有する塗料で塗装した塗装品を容器内に収納した後、制御手段により減圧ポンプを駆動すると、容器内が減圧されて塗膜に含有する溶剤が気化し、塗装の乾燥が短時間に行われる。 After storing painted items with paint containing thinner-based solvents in a container, control When the vacuum pump is driven by means, the pressure inside the container is reduced and the solvent contained in the coating film is removed. It evaporates and the paint dries in a short time.

【Example】

以下、図により本考案を詳細に説明する。図１は、本考案に係る塗装乾燥装置の一実施例である。図において、１は本装置の容器で、容器１の正面開口部２の周囲には気密性を図るためのシーリングゴム３が装着されている。正面開口部２には、容器１を封止する開閉ドア４がヒンジ５を介して設けられている。また、開閉ドア４と容器１側面間には、ドア開放用のスプリング６が取付られている。 Hereinafter, the present invention will be explained in detail with reference to the drawings. FIG. 1 shows an embodiment of a paint drying apparatus according to the present invention. In the figure, 1 is the container of this device, and the area around the front opening 2 of the container 1 is airtight. A sealing rubber 3 is attached for this purpose. The container 1 is sealed in the front opening 2. An opening/closing door 4 is provided via a hinge 5. In addition, the opening/closing door 4 and the container A spring 6 for opening the door is attached between one side.

【０００８】容器１の上部には、支持ブラケット７を介して減圧ポンプ８が設けられていると共に減圧ポンプ８と容器１間が、減圧用開閉弁（電磁弁）９を介してパイプ１０で連結されている。パイプ１０には、また大気開放用開閉弁（電磁弁）１１が連結され、更にドアシリンダ用開閉弁（電磁弁）１２を介してドアシリンダ１３に連結されている。ドアシリンダ１３の先端１４は、前記開閉ドア４に取付られている。[0008] A vacuum pump 8 is provided at the top of the container 1 via a support bracket 7. At the same time, a pipe 1 is connected between the pressure reduction pump 8 and the container 1 via a pressure reduction on-off valve (electromagnetic valve) 9. Connected with 0. An on-off valve (electromagnetic valve) 11 for opening to the atmosphere is also connected to the pipe 10, and a door It is connected to a door cylinder 13 via a cylinder on-off valve (electromagnetic valve) 12 . A tip 14 of the door cylinder 13 is attached to the opening/closing door 4.

【０００９】前記支持ブラケット７上には、吊り下げブラケット１５が設けられ、吊り下げブラケット１５はコンベア１６に支持され、一定方向に搬送されるようになっている。前記容器１の側部には、スイッチ１７を有するコントロールボックス（制御手段）１８が設けられ、コントロールボックス（制御手段）１８の出力側に、減圧ポンプ８，電磁弁からなる各開閉弁９，１１，１２が電気的に接続されている。また、吊り下げブラケット１５に設けられた端子１９と減圧ポンプ８，電磁弁からなる各開閉弁９，１１，１２間及びコントロールボックス（制御手段）１８間が電気的に接続されている。[0009] A hanging bracket 15 is provided on the support bracket 7, and a hanging bracket 15 is provided on the support bracket 7. The bracket 15 is supported by a conveyor 16 and is conveyed in a fixed direction. There is. A control box (control manual) having a switch 17 is provided on the side of the container 1. stage) 18 is provided, and the output side of the control box (control means) 18 is provided with a reduced pressure A pump 8 and on-off valves 9, 11, and 12 each consisting of a solenoid valve are electrically connected. In addition, the terminal 19 provided on the hanging bracket 15, the pressure reducing pump 8, and the solenoid valve between each on-off valve 9, 11, 12 and control box (control means) 18 are electrically connected.

【００１０】そして、シンナ系の溶剤を含有する塗料、例えば、フタル酸樹脂エナメルで塗装した塗装品を容器１内に入れてスイッチ１７をＯＮすると、まず、減圧用開閉弁９及び大気開放用開閉弁１１が閉鎖されて開放されたドアシリンダ用開閉弁１２を介してドアシリンダ１３が負圧となり、開閉ドア４が閉鎖される。ドアシリンダ用開閉弁１２は、開閉ドア４が閉まると閉鎖する。0010 Paints containing thinner-based solvents, such as phthalate resin enamels, are then used. When the coated product is placed in the container 1 and the switch 17 is turned on, the depressurization opening/closing Opening/closing valve 1 for door cylinder with valve 9 and opening/closing valve 11 for opening to atmosphere closed and opened 2, the door cylinder 13 becomes negative pressure, and the opening/closing door 4 is closed. door siri The on-off valve 12 for the driver is closed when the on-off door 4 is closed.

【００１１】次に、減圧用開閉弁９が開いて、容器１内の減圧が行われて、塗装品の塗膜に含有する溶剤が気化される。減圧は、約２００ｔｏｏｒであり、指触乾燥は約２．５分である。従って、従来の自然乾燥１５分に比較して１／６に短縮される。その後、規定時間経過後、減圧ポンプ８が止められ、大気開放用開閉弁１０が開き、大気開放となる。[0011] Next, the pressure reduction on-off valve 9 is opened, the pressure inside the container 1 is reduced, and the paint film of the painted product is The contained solvent is vaporized. The reduced pressure is about 200 toor, and the dryness to the touch is about 2 ．． It's 5 minutes. Therefore, compared to the conventional natural drying time of 15 minutes, the time is reduced to 1/6. Then, after a specified period of time has elapsed, the pressure reducing pump 8 is stopped and the opening/closing valve 10 for opening to the atmosphere is opened. It opens to the atmosphere.

【００１２】然る後、ドアシリンダ用開閉弁１２が開いてドアシリンダ１３の負圧力がなくなり、開閉ドア４はドア開放用スプリング６のスプリング力により開放される。上記操作は、コントロールボックス（制御手段）１８内のタイマー又はプログラムにより行われ、減圧時間は塗料の種類、塗膜厚さ等に応じて予め設定しておいた基礎データに基づいて行う。0012 After that, the door cylinder on-off valve 12 opens and the negative pressure in the door cylinder 13 disappears. The opening/closing door 4 is opened by the spring force of the door opening spring 6. The above operation is performed using the timer or program in the control box (control means) 18. The decompression time is set in advance according to the type of paint, coating thickness, etc. Based on the basic data obtained.

【００１３】尚、安全を図るために、容器１上に圧力調整弁２０を設けておいて容器１内が下がり過ぎないようにする。然して、塗装の乾燥時間が短縮され、塗装後、早々に梱包等の次の作業が行われて作業能率が向上する。しかも、オーブン等で加熱強制乾燥するような火災の危険性もない。[0013] For safety, a pressure regulating valve 20 is provided on the container 1 to ensure that the inside of the container 1 is Make sure it doesn't fall too low. As a result, the drying time of the paint is shortened, and the next work such as packing can be done quickly after painting. This improves work efficiency. In addition, there is a risk of fire caused by forced drying in an oven, etc. There's no danger.

【００１４】本考案はシンナ系の溶剤を含有する塗料で塗装した塗装品の乾燥に適するが、水系塗料で塗装した塗装品の乾燥にも応用できるものである。[0014] This invention is suitable for drying painted products painted with paints containing thinner-based solvents, but It can also be applied to drying painted products painted with water-based paints.
