[0005] In the case of the example shown in FIG. 4, an air atomizing method is adopted, and the coating material is a water-soluble coating material having a high boiling point of 100 ° C., so that it can cover the entire temperature range from normal temperature to high temperature. The diameter of the nozzle is as large as φ0.5 mm to prevent nozzle clogging due to the water-soluble paint.

On the other hand, in the paint system, the paint compressed by a paint compressor (not shown) is supplied to the paint discharge nozzle 1 after the pressure is adjusted and set by a pressure regulating valve. In this case, the paint pressure and the air pressure to be set are generally controlled by the temperature of the steel sheet. For example, when the steel sheet temperature is high, the paint discharge pressure is reduced and the air discharge pressure is increased. The distance between the tip of the nozzle and the steel plate (nozzle height) is also adjusted according to the temperature of the steel plate, and the distance between the steel plates is controlled to be shorter as the temperature becomes higher. Such compressed paint is discharged from the paint discharge nozzle 1 which is drawn in by the nozzle tip distance L, and compressed air is discharged from the air / washing liquid discharge nozzle 3 and mixed in the nozzle to form a prescribed φ4.
Dot spray marking is performed on the steel plate as dots of mm. Thereafter, the cleaning liquid is supplied and discharged from the cleaning liquid hole 4 to clean the nozzle.

In FIG. 3, the curve A is a characteristic curve plotting the relationship between the dot diameter and the nozzle tip distance L.
When the nozzle tip distance is around L = 0, that is, when there is no difference between the nozzle tip 2 and the paint discharge nozzle 1, the paint and the air are mixed outside the nozzle, and the air is diffused to increase the dot diameter to 8 mm. I have. Further, the paint discharge nozzle 1 is retracted from the nozzle tip 2 and the nozzle tip distance L = 0.
When it reaches 5mm, along with the effect of reducing the nozzle diameter to 0.2mm and suppressing diffusion, the paint and air are mixed in the nozzle and the spread of air is suppressed, and the dot diameter becomes 4mm as specified. As a result, clear marking can be performed by the air atomizing method without bleeding.

According to this embodiment, the nozzle diameter is reduced from φ0.5 mm to φ0.2 mm in the conventional example, and the paint discharge nozzle 1 is moved toward the nozzle tip distance L =
The paint and air can be mixed in the nozzle because it is retracted by 0.5-1.0mm, so that the dot φ4mm and dot pitch 5mm can be maintained without spreading the air, and the normal temperature (~ 90 ° C) range Airless printing, 90 ~
In the high sound range of 300 ° C., if air atomizing printing is performed, clear marking can be performed in all temperature ranges, and it is also suitable for printing thick products.
