Air, air, atomization, air, etc. are supplied, and the air is always 4. 2. The person is placed in an environment where there is a risk of fire or burns. In particular, in electrostatic coating machines that use high-voltage static electricity, .tau. is a sufficient cause of flame generation. 5"- As a result, i"i11 flammable material C Once a certain vaporized organic solvent is exposed to a flame, the flame will be promoted by a small amount of air, and the inside of the painting booth will always be in flames. dangerous goods,
The present invention does not take into account the problems of the prior art: A) The amount of air in the paint booth, which is a factor in the generation of flames, In other words, the purpose is to reduce the amount of oxygen as much as possible, prevent flame generation, and provide a coating device. In order to achieve this, the present invention provides a painting booth 4 which defines a ``painting ring'' without painting the object.
t. A coating device installed in the coating booth and consisting of a coating machine that sprays the object to be coated and the paint.
11.Install a safety gas supply means to supply a safety gas such as nitrogen gas, inert gas, etc. to the flameproof gutter in the painting booth. '￥17(to6
8 [Function] - Noyo): ・This defines the nitrogen gas, ', , J: S, Near,: All gas supply 11. Insert a safety gas such as nitrogen gas or inert gas into the painting booth by means of The space inside the painting booth is filled with f. Replace 9 with safety gas 1'': This reduces the amount of oxygen in the painting booth, and prevents the generation of flames. [Example] Hereinafter, 1. Example of the present invention will be described with reference to the attached drawings.
B) Explain in detail. Drawings - Hey τ, 1 is a painting station -: installed in the hall, etc.
The painting booth 1 has a circular booth or a corner consisting of a peripheral wall lΔ and a ceiling wall IB, and its interior is defined by painting pulleys TIC and 1. I'm sleeping. In the inner wall part IA of the painting booth l, there are a plurality of squares 12.2, .

An oxygen detector for detecting oxygen, named oxygen detector t8:
For example, a magnetic oxygen sensor that takes advantage of the constant 6-temperature nature of porcelain a degree, uses electrodes on the inner and outer surfaces of zirconia porcelain, and takes advantage of the fact that electromotive force is generated depending on the oxygen concentration.

Oxygen concentration detection from the oxygen detector 18 A3! - Knee is output to the oxygen concentration display 11 installed outside the coating gas and displayed as oxygen concentration, and 1.4''' is output to the nitrogen gas supply (1 unit @ l 5). Here, the oxygen concentration display 19 is used to display the current oxygen concentration to prevent the noise from entering the painting booth 1, which is in an oxygen-deficient state. This embodiment describes the operation of the power supply j configured in this way. First, under the control of the nitrogen gas supply control device l:), the nitrogen gas vibrator 17 is T' Supply nitrogen gas into the painting booth 1 and set the oxygen concentration to a predetermined value.
- Introducing oxygen at 4 degrees in a state of inactivity. 5. IH, exposing air is supplied to the coating machine 8 via the nitrogen gas valve 13. −
Supply Ping Air. In this state, the high voltage from the high voltage generator 12 is passed through the high voltage cable IT to 1. At the same time, the paint from the paint pump lO is supplied to the paint machine 8 through the paint vibrator 9 and the paint discharged from the paint machine 8 is nitrogen gas. Atomized by exposure air,
The paint particles are formed between the coating material 6 suspended from the conveyor 5 and are applied to the coating material 6 along the electrostatic path. At this time, the sprayed batter is shaped by shaping air made of nitrogen gas to obtain a good coating film. So! , According to the present embodiment, supplying raw gas into the coating booth 1]2. C Replace with air and create a nitrogen gas atmosphere 11
2. Because of this, there is no risk of ignition even in a state where a large amount of vaporized solvent is present, and flame generation is reliably prevented. In addition, by supplying nitrogen gas through the atomizing air and shaping air of the coating machine 8, safety can be maintained, and the oxygen concentration in the coating booth 1 can be adjusted to a predetermined color amount F. This makes it easier to suppress. Detect the oxygen concentration inside the painting booth 1 with the oxygen detector 1 and display it on the oxygen level indicator 18 installed outside the painting booth 1. 5) It is possible to prevent workers from accidentally entering the painting booth 1, which is in an oxygen-deficient state, and to improve the safety of work management. In the example, the safety gas according to the present invention and the 1.2,000 yen gas are exemplified. 3. In the embodiment, a coating machine applied to the present invention and I. Although the air exposure type electrostatic painting gun was shown as an example, i'a I
A TE atomization atomization 9 mist rolling atomization type loading machine may also be used. There is no need to use nitrogen gas because of shaping air and nized air, and therefore, there is no need for the nitrogen gas vibrator 13.Furthermore, the object to be coated 6 should not be hung from the conveyor 5 by 1", such as an automobile body. At the same time, it may be placed on a Pi cart running on the 11 marrow (on the other hand, in the case of canned products, it may be fixed on the ground. Furthermore, the nitrogen gas generator 14 and the 7 gas supply may be Although the control device 15 is a specific example of the safety gas supply means according to the present invention, the present invention is not limited to this one unit example, and the present invention is not limited to this one example. Configuration 17 may be used as a safety gas supply means. [Effects of the Invention] The coating apparatus according to the present invention is as described above [inside the coating booth] and supplies nitrogen gas. Even if the air is replaced! 91, the paint booth is constructed to reduce the oxygen concentration, and a large amount of organic solvents, etc. are used, accidents such as fires and explosions inside the paint booth can be prevented. This can be prevented in advance, and even in the case of unmanned painting lines, safety can be maintained to a certain extent.
