が悪くなるなど所謂汎用性がない欠点があつた。 In general, the baking and cooling conditions for paints vary depending on the type of paint (oil-soluble, water-soluble, etc.), the thickness of the paint film, etc.
For example, after baking at a high temperature of about 230 degrees Celsius, you can use a shower of water to quickly cool it down to near room temperature, or after baking at a relatively low temperature of about 170 degrees Celsius, you can gradually cool it by blowing air on it. There are various things that need to be done. Therefore, the required length of the heating zone and the required length of the cooling zone differ depending on the paint used, and in conventional baking equipment, equipment designed to bake one type of paint may not be as efficient when baking other paints. There were drawbacks such as a lack of versatility, such as poor performance.
本発明はこのような従来の欠点に鑑みて為され

ようにしたことにある。 The present invention has been made in view of these conventional drawbacks. That is, the present invention can bake and cool both oil-soluble paints and water-soluble paints, and can also be used in cases where the baking or cooling conditions are quite different, such as those that are baked at high temperatures and those that are baked at relatively low temperatures. However, the present invention provides a continuous coating and baking device that can be used as needed. The gist of the present invention is to provide an intermediate zone between the heating zone and the cooling zone, which is separated from both zones.
The intermediate zone is provided with pipes at the boundary with the heating zone and the boundary with the cooling zone, respectively, so that the gas at these boundary areas can be sucked in by a blower and exhausted to the outside, and the intermediate zone can be heated. A conduit for supplying gas and a conduit for supplying cooling gas are provided side by side, so that either heating gas or cooling gas can be selectively supplied to the intermediate zone.

る。 Next, the operation of this continuous coating and baking apparatus will be explained.
Approximately 230% like the material coated with oil-soluble paint first
In the case of water cooling after baking at a high temperature of about °C, heating gas is supplied to intermediate zone B to carry out baking in both heating zone A and intermediate zone B, and then cooling zone C.
Cool with water and dry. The operation at this time is to open the on-off valve 22 provided in the pipe line 21 to supply heated gas to the intermediate zone B so that the paint can be dried and baked also in the intermediate zone B. Then, the on-off valve 20 of the pipe line 18 provided at the boundary between the intermediate zone B and the cooling zone C is opened, and the gas at this boundary is sucked in by the blower 11, so that the heated gas in the intermediate zone B and the cooling zone C are heated. Cut off communication with gas. In that case, blower 2
5 is stopped, on-off valve 28, on-off valve 31, on-off valve 1
9 is closed. In this way, the material S is heated in the heating zone A.
By the time it passes through each of the zones 1a to 1c and the intermediate zone B, the temperature is raised to a predetermined temperature (approximately 230°C) and the film is sufficiently dried and baked. The material S is then transferred to the cooling zone C, where it is first gradually cooled to a temperature of about 160° C with cold air sucked by the blower 8 in the air cooling chamber C 1, and then slowly cooled to a temperature of about 160° C. in the water cooling chamber C 2 through the nozzle 12, It is rapidly cooled down to near room temperature (approximately 45℃) by the cooling water spouted from 12,
Finally, in the drying chamber C3 , cool air sucked by the blower 15 is blown to evaporate the moisture and dry the material.

In the case of air cooling after baking at a relatively low temperature of about 170°C, cooling gas is supplied to intermediate zone B, and heating zone A
After baking the material S, it is air cooled in an intermediate zone B and a cooling zone C. The operation at this time is to operate the blower 25 of the pipe line 24 connected to the intermediate zone B, open the on-off valve 28, open the on-off valve 31 of the pipe line 29, and open the automatic flow rate control valve 27 and the automatic flow rate control valve 30. to control the gas pressure in the intermediate zone B to be constant.
supplying atmospheric air as a cooling gas to the Then, the on-off valve 19 of the pipe line 17 provided at the boundary between the heating zone A and the intermediate zone B is opened, and the gas at this boundary is transferred to the blower 11.
to shut off the flow between the heating gas in the heating zone A and the cooling gas in the intermediate zone B. Further, the on-off valve 22 of the conduit 21 connected to the intermediate zone B is closed and heating gas is not supplied to the intermediate zone B. In this way, the material S is heated to a predetermined temperature (approximately 170°C) by the time it passes through each zone 1a to 1c of the heating zone A, is sufficiently dried and baked, and is then transferred to the intermediate zone B and passed through the pipe line 24. Cooling gas supplied through the tube is blown and slowly cooled. The material S is further transferred to the air-cooling room C1 , where it is further cooled by the cold air blown out from the blower, and then passed through the water-cooling room C2 , where it is cooled down to room temperature by being blown with cold air in the drying room C3 . It is. That is, in this case, the material S can be cooled to a predetermined temperature by passing through the intermediate zone B, the air-cooling chamber C 1 and the drying chamber C 3 and being blown with cooling gas. Even in the case of paint, by adding intermediate zone B as a cooling zone, a sufficient required length of the cooling zone can be ensured.

できるものである。 As described above in detail with respect to the embodiments, the present invention provides an intermediate zone between the heating zone and the cooling zone, which is separated from both zones, and the intermediate zone is at the boundary with the heating zone and between the cooling zone. A pipe line is provided at each boundary so that the gas at the boundary part can be sucked in by a blower and exhausted to the outside, and a pipe line for supplying heating gas and a pipe line for supplying cooling gas to the intermediate zone are provided. Since this system is installed in parallel and allows either heating gas or cooling gas to be selectively supplied to the intermediate zone, if heating gas is supplied to the intermediate zone now, high-temperature heating can be handled in the heating zone and the intermediate zone. Since the required length can be secured as much as possible, it is possible to achieve high-temperature baking such as oil-soluble paints, and if cooling gas is supplied to the intermediate zone, the required length for cooling can be achieved without water cooling between the intermediate zone and the cooling zone. Since a long cooling zone can be formed, it can also be applied, for example, to baking water-soluble paints. As described above, according to the present invention, it is possible to provide an extremely versatile paint baking apparatus that can suitably handle even if the baking or cooling conditions are considerably different.
