〔産業上の利用分野〕
本発明は、省エネルギ化をより向上するようにした塗装
ブースに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a painting booth that further improves energy saving.
自動車の塗装は、温度調整及び湿度調整された密閉の塗
装ブース内で行なわれる。Automotive painting is performed in a closed paint booth with controlled temperature and humidity.
従って塗装ブースは、温度及び湿度調整用の熱エネルギ
が消費きれる。Therefore, the paint booth can consume less heat energy for temperature and humidity adjustment.
又一方にお−で、上記温度及び湿度調整された空気を塗
装ブース内に給排気するためにファンが使用され、この
ファンの駆動に電気エネルギが消費される。On the other hand, a fan is used to supply and exhaust the temperature- and humidity-controlled air into the coating booth, and electrical energy is consumed to drive the fan.
塗装ブースの技術的な問題として、前記給気量と排気量
のバランスがある。A technical problem with paint booths is the balance between the amount of air supplied and the amount of air discharged.
即ち、給気量よシも排気量の方が多いときは、塗装ブー
ス内は負圧になって外気を吸引し、この外気と共に塵埃
が塗装ブース内に侵入して不都合を生じ、又この逆に排
気量の方が少ないときは、余分な空気が供給され、省エ
ネルギの観点よシ好ましくない。In other words, when the exhaust volume is larger than the supply air volume, the inside of the painting booth becomes negative pressure and outside air is sucked in, and dust enters the painting booth together with this outside air, causing inconvenience, and vice versa. If the exhaust volume is smaller than that of the previous one, excess air will be supplied, which is undesirable from the point of view of energy saving.
このような理由で、塗装ブースの給気量と排気量の関係
には、バランスのとれた最適値が存在する。For this reason, there is a balanced optimal value for the relationship between the air supply amount and the exhaust amount of the paint booth.
又、塗装ブースには負荷変動があり、塗装作業中と、清
掃や塗装機器の調整等の非塗時とで負荷が異り、又、塗
装作業中でも被塗装物の点数、或は大きさや形状によっ
ても負荷が異る。In addition, the load on the painting booth varies, and the load differs during painting work and when not painting, such as cleaning or adjusting painting equipment, and even during painting work, there are changes in the number of objects to be painted, or the size and shape of the objects to be painted. The load also differs depending on the situation.
従来の省エネルギ化を考慮した塗装ブースとして、特開
昭５７−１６５０６２号公報に示されるように、塗装ブ
ース内を複数のゾーンに区画し、この区画ゾーン単位で
給気及び排気を０Ｎ−ＯＦＦして、省エネルギ化を行な
ったもの（以下区画ゾーン型という）がある。As shown in Japanese Unexamined Patent Application Publication No. 57-165062, a conventional painting booth designed to save energy is divided into a plurality of zones, and air supply and exhaust are turned off in each zone. There is a type (hereinafter referred to as a zone type) that saves energy.
又塗装ブースの負荷変動に応じて塗装ブース内の風速を
変える技術（ｔｖ！ｆ開昭５９−２２６７８号公報）が
ちる。There is also a technique (TV!F Publication No. 59-22678) for changing the wind speed inside the coating booth in response to load fluctuations in the coating booth.
この技術は、塗装時と非塗装時において、供給風量と排
気風量を制御し、明細書中に例示するように塗装時にお
ける塗装ブース内の望見の流速（排気量−給気量）が０
．５ｍ／３非塗装時は０．２ｍ／ｓになるようにしたも
のである。This technology controls the supply air volume and exhaust air volume during painting and non-painting, and as exemplified in the specification, the desired flow velocity (exhaust air volume - supply air volume) in the painting booth during painting is 0.
．． 5m/3 When unpainted, the speed is 0.2m/s.
上記従来の塗装ブース（（お１ハて、区画ゾーン盤は、
区画されたゾーンごとに負荷変動に対する省エネルギ化
が行なわれていな絶ので、十分とは云えない問題がある
。The above conventional painting booth ((First step, the division zone board is
There is a problem in that energy saving in response to load fluctuations has not been carried out in each divided zone, and therefore cannot be said to be sufficient.
又、負荷変動に応じて塗装ブース内の風速を変える方式
の場合は、塗装ブースの負荷に合せて供給ファンの風量
と排気ファンの風量全個別に制御して風速を変えるので
、塗装ブース内の圧力が過負圧になる可能性がある。In addition, in the case of a method that changes the air speed in the painting booth according to load fluctuations, the air volume of the supply fan and the air volume of the exhaust fan are individually controlled to change the air speed according to the load of the painting booth. Pressure may become over-negative.
このように塗装ブース内の圧力が過負圧になると塗装ブ
ース内に外気を吸引することになシ、塗装ブース内への
塵埃の侵入の可能性が太きいという問題がある。If the pressure inside the painting booth becomes excessively negative as described above, there is a problem in that outside air cannot be sucked into the painting booth and there is a high possibility that dust will enter the painting booth.
又、塗装ブース内に外気を吸引することにより、塗装ブ
ース内の温度と湿度が変動し、塗装に対して悪影響を与
えると共に、所定の温度及び湿度に調整するのに時間を
要し、生産性が低下するという問題がある。In addition, by sucking outside air into the painting booth, the temperature and humidity inside the painting booth fluctuate, which has a negative impact on the painting process, and it takes time to adjust the temperature and humidity to the desired level, reducing productivity. There is a problem that the amount decreases.

9a, 9b, and at the same time, the exhaust air volume adjusting device 10a,
10E), lla, and 1it) are also operated to adjust the air volume of each 77 inches.
この風量調整により温調器６，７の負荷も変るので、こ
の負荷変動に応じて＠調器６．７の熱源も調整される。Since the load on the temperature controllers 6 and 7 changes due to this air volume adjustment, the heat source of the @regulators 6 and 7 is also adjusted in accordance with this load variation.
又は、非塗装時においては、温調器６，７ヲ停止１せる
