Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a painting booth (painting room) used for painting various vehicles.

[0002]

[Prior art]

 Conventional painting booths installed in factories and used for painting vehicles have opening and closing doors for loading and unloading vehicles on the front and one side or both sides, and a blast fan (sirocco fan) is used during painting. While forcibly supplying the same amount of air as the exhaust volume to ventilate the room, at the time of drying, the exhaust is stopped to forcibly take in fresh air and the dry air warmed by the warm air blower (burner) is used. By sending it into the room, the temperature inside the room is raised to a temperature suitable for drying the paint.

[0003]

[Problems to be solved by the device]

 However, in the conventional coating booth configured as described above, the dry air warmed by the hot air blower (burner) is sent into the room as it is to dry the coating, so various types of particles such as fine particles generated when the burner burns are used. There was a problem that the dust was sent into the room together with the dry air, and the dust adhered to the painted surface to stain the paint.

Further, it has been considered that the above-mentioned dry air is supplied through a filter provided on the ceiling surface of the room to collect the above-mentioned various kinds of dust and to make the dry air clean. Since a high-performance filter cannot be used to ventilate the dry air without it, it is impossible to completely shut out various dust with the filter. It was a cause of soiling.

Therefore, the technical problem of the present invention is to provide a coating booth that can dry the coating cleanly with completely clean dry air and can efficiently coat and dry the vehicle. is there.

[0006]

[Means for Solving the Problems]

 Means taken in the present invention to solve the above technical problems are as follows. It is equipped with a ventilation device that supplies clean air from the ceiling side of the room through the filter, sucks dust-containing air that has become dirty from the paint from the bottom side, and exhausts it to the outside of the room. In a vehicle coating booth configured to paint the vehicle in this room by providing an opening and closing door for putting in and out,

(1) The opening / closing door provided on the one side surface or both side surfaces is a sliding type door that opens and closes by electric power, and the inside surface of the room including the sliding type opening / closing door has a front surface. Install a far-infrared radiation dryer configured to irradiate the far-infrared radiation emitted from this heat radiation tube toward the room by piping a heat radiation tube for combustion gas inside the open reflective case.

(2) The reflection case body in which the heat radiation tube is piped and the lighting case body in which a plurality of fluorescent lamps are attached are integrated to form a slide type opening / closing door, and the opening / closing door has the above-mentioned structure. Install a burner that sends combustion gas to the heat radiation tube and a fuel tank.

[0009]

[Action]

 The above means operate as follows. According to the means described in (1) above, the interior of the vehicle is dried by the clean far-infrared radiation emitted from the far-infrared radiation dryer, so that the coating of the vehicle can be cleaned cleanly without adhering dust. It can be dried in a short period of time, and vehicles can be moved in and out of the booth freely through the opening and closing doors on the front and one side or both sides. It is electrically operated, and it also opens and closes vertically with the far-infrared radiation dryer, allowing the vehicle to be smoothly loaded and unloaded from the side without being disturbed by the far-infrared radiation dryer.

According to the means described in (2) above, the reflection case body of the far-infrared radiation dryer and the lighting case body to which the fluorescent lamp is attached form a slide type opening / closing door provided directly on the side of the booth. Since there is no need for piping or wiring, the booth configuration can be significantly simplified. In addition, the burner and fuel tank of the far infrared radiation dryer are attached to this sliding door and operate together to open and close the vehicle. It is possible to smoothly take in and out the fuel without being obstructed by such burners, fuel tanks, or piping. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.

When the opening / closing door 10 and the side wall plate 9 are opened and closed along the guide columns 8 and 8, the far-infrared radiation dryer 11 and the fluorescent lamp 12S for illumination are integrally formed to move up and down. Therefore, when the vehicle CR is taken in and out from the side, it can be smoothly performed without being disturbed by the far infrared radiation dryer 11, the fluorescent lamps 12S, ... Or the piping and wiring of these.

Next, when the vehicle CR is painted in the booth 1, both the air supply fan 5 and the exhaust fan 6 are operated to forcibly ventilate the room 1T, and the coating is dried. Stops the exhaust fan 6 and only takes in fresh air by the air supply fan 5, and at the same time, the far infrared radiation emitted from the far infrared radiation dryer 11 dries the room 1T in a clean state and paints it. You can dry it cleanly without attaching dust to the surface.

[0022]

[Effect of device]

 As described above, according to the vehicle coating booth of the present invention, the coating can be dried cleanly by using the far-infrared radiation dryer, so that the coating surface can be dried without dust. In addition to increasing the commercial value of the vehicle, the far-infrared radiation dryer and lighting are installed on the side opening / closing door itself where the vehicle is taken in and out, and the burner and fuel tank of the dryer are also installed on this opening / closing door. No need for ducts for dryers or wiring for lighting, simplification of booths and cost reductions are possible, and vehicle loading and unloading from the side is obstructed by piping and wiring. It has the advantage of being able to perform smoothly and smoothly and to greatly improve the efficiency of painting work, and its practical value is extremely high.
