Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a coating device for coating roofs and walls of factories, etc., and more specifically, to an improvement of a dustproof hood in the coating device.

[Prior Art] Generally, when the roofs and walls of buildings such as factories are painted by spraying a gun using a painting device, the paint mist scatters around the gun, so conventionally, a dustproof hood was placed around the gun. There is.

Fig. 3 shows an example of a conventional roof coating device.A rope 1 is hoisted up and down by a hoisting device installed at the ridge of the roof, and the coating device body frame 2 is moved via wheels 3. At the front of the main body frame 2, a dust-proof hood 5 communicating with the dust-collecting blower 4 installed on the main body frame 2 is disposed, and inside the dust-proof hood 5, the main body A plurality of spray guns 7 connected to a paint tank 6 mounted on a frame 2 are installed, and mist generated during painting work is sucked into a dust collection blower 4 from a dustproof hood 5. 8 is a skirt for closing the gap between the dustproof hood 5 and the roof surface.

[Problems to be Solved by the Invention] However, in the conventional painting apparatus, although the dustproof hood 5 is arranged around the spray gun 7 to prevent the mist from scattering to the outside, the spray gun 7 itself had the problem of being easily contaminated by mist.

The present invention attempts to solve this problem.

[Means for Solving the Problems] The present invention provides a coating apparatus in which a hood is used to prevent mist generated by gun blowing from scattering to the outside, and a dust collecting blower is used to suck it up. , a hollow part communicating with the outside is provided by a partition member, a gun is installed in the hollow part so that only the nozzle part is located inside the hood, and the mist generated in the hood is dissipated by the partition member. It has a structure in which a duct part is formed to lead the inside of the hood from the front part to the rear part through the upper part.

[Effect] Therefore, the mist generated by gun blowing is
Due to the presence of the partition member, the gun is not contaminated, and suction is stably carried out from both the front and the rear inside the hood.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, in the present invention, a horizontal hollow portion 1 is provided in the gun 7 installation portion of the dustproof hood 5 so as to communicate with the outside through a partition member 9.
0 is provided, and the main body portion 7a of the gun 7 is provided with a hollow portion 10.
position the nozzle part 7b of the gun 7 in the hood 5.
The partition member 9 forms a duct portion 5a that guides the mist generated in the hood 5 from the front part of the hood 5 to the rear part through the upper part. In addition, Figures 1 and 2
In the figure, the same reference numerals as in FIG. 3 indicate the same parts.

In such a configuration, when painting is performed while driving the dust blower 4, the mist generated by gun blowing is sucked by the dust blower 4 and collected by a filter (not shown). At this time, since the main body 7a of the gun 7 is separated from the mist generation area by the partition member 9, contamination by the mist is prevented. Also, since the duct portion 5a is formed, the mist flow is sucked from both the front and rear parts of the hood 5 as shown by the arrows shown by solid lines and the arrows shown by broken lines in FIG. This ensures stable coating.

In the embodiment described above, the duct portion 5a is configured to be detachable so that the gun 7 can be easily installed and maintained, but it is not necessarily necessary to make it detachable. Also, in the above embodiment, the case of a roof coating device was illustrated, but
It may also be configured for wall use.

[Effects of the invention] As explained above, according to the coating apparatus of the invention, the dust-proof hood is provided with a hollow portion that communicates with the outside through a partition member, and only the nozzle portion is placed inside the hood in the hollow portion. Since the gun is installed so that it protrudes, it is possible to prevent the main body of the gun from being contaminated by the mist generated during painting, and a duct is provided so that the generated mist can be sucked in from both the front and rear of the hood. Therefore, excellent effects such as no turbulence in the flow of mist and stable coating can be achieved.
