Description

[Detailed explanation of the idea] The present invention relates to an automatic painting device.

The painting equipment that moves and paints the outer panels of the hull, etc.
To prevent the paint mist sprayed by the paint gun from scattering outside, the area around the paint gun is covered with a hood, and the paint mist is sucked in and treated as a mist before painting. However, the hood cannot be in close contact with the surface to be painted, such as the outer panel of a ship's hull, and the coating equipment must be moved along the surface to be painted, so a certain distance or more is required between the surface to be painted and the hood. Paint mist leaked out from the gaps, polluting the atmosphere, and adhered to peripheral equipment. Also,
Since the paint mist is treated by suction, the paint mist adheres to and accumulates on the reciprocating drive part of the paint gun inside the hood, and removing the paint mist after painting is time-consuming and requires the use of solvents. Therefore, the lubricating oil and grease on the sliding surfaces and lubricating parts of the reciprocating drive section are removed, making maintenance of the reciprocating drive section of the painting gun time-consuming.

This invention was developed in consideration of the above points, and even though there is a gap above a certain level between the surface to be painted and the hood, it is possible to reliably prevent the paint mist from flowing outside and eliminate the atmosphere. It can prevent paint mist from staining or adhering to peripheral equipment, etc., and even though the paint mist is suctioned,
To provide an automatic painting device which can prevent painting mist from adhering to a reciprocating drive part of a painting gun and eliminates the need for maintenance such as removal of paint mist and maintenance of the reciprocating drive part.

The present invention will be explained below based on examples.

Fig. 1 shows an example of the use of the present invention, in which a coating device 1 is mounted on a self-propelled machine 3 installed in a dock 2, and is used to movably coat a surface 5 of the outer panel of a ship 4. It is something. The coating device 1 is pivotally mounted on a pedestal 7 at the tip of an extendable and pivotable arm 6 of a self-propelled machine 3 via a support member 8, and the front side is open as shown in FIGS. 2 and 3. A tilting device 10 such as an electric hydraulic cylinder is disposed on both sides of the box-shaped hood 9 so that it can be tilted at a predetermined angle so as to face the curved surface 5 to be painted. As shown in FIG. 2, the hood 9 is equipped with a painting gun 12 at the front thereof, which is driven reciprocatingly over a predetermined distance by a reciprocating drive device 11, which will be described later.
A mist filter 13 is installed in the rear part, and an exhaust fan 14 with a capacity is arranged in the rear part to suck the painting mist generated by the painting gun 12 into the hood 9 and to make the mist filter 13 absorb and capture it to exhaust it. The exhaust is treated by a dust device (not shown).
As shown in FIGS. 2 and 3, an air blowing section 15 is arranged on the side circumference of the hood 9 in a double cylindrical shape with the hood 9, and an air blowing guide 16 is attached to the front end of the air blowing section 15. 9 so that the air is blown out to the hood 9 side over the entire circumference, and an air supply fan (not shown) with a predetermined capacity is used to blow the air out from the air supply connection port 17 arranged on the rear of the hood 9. The air to be supplied is made to flow into the air blowing part 15 to seal the paint mist generated by the painting gun 12 and flowing out along the surface to be painted 5 to the outside, and also to the exhaust fan 14 side. I try to make it flow towards me. On the outside of the air blowing part 15, as shown in FIG.
The outside air blown onto the coating device 1 is made to flow away along the outer peripheral surface of the coating device 1. One side of the air blowing part 15 on the side of the hood 9 is made slightly wider than the other side, and as shown in FIG. The side plate 20 is removably installed and is driven by a drive source 21 provided on the outer surface of the side plate 20 and having a predetermined reduction ratio. Then, one end of the holding member 22 that holds the painting gun 12 is attached to the reciprocating drive unit 19, and a narrow groove-shaped opening is opened to a predetermined length on the side surface of the hood 9 over the movement range of the painting gun 12. The holding member 22 is protruded from the portion 23 into the hood, and the painting gun 12 is
It is installed in the hood 5 so that it can be moved back and forth for painting. 24 is a proximity sensor such as an ultrasonic detection type for installing the coating device 1 at a predetermined distance from the surface 5 to be coated.

As shown in FIG. When the painting gun 12 and the like are operated to paint the surface 5 to be painted, the paint mist that is sprayed by the painting gun 12 and does not adhere to the surface 5 to be painted is removed from the air blowing part 15 as shown in FIG. The air blown toward the painted surface 5 prevents the air from flowing out through the gap between the painted surface 5 and the hood 9, and
The air is blown inward by an air jet that is blown onto the inside of the hood 9 by the air blowing guide 16, and is sucked by the exhaust fan 14 and flowed to the rear of the hood 9, and is treated as a mist by the mist filter 13. The dust is then exhausted to a dust removal device. Therefore, even if there is a gap above a certain level between the surface to be painted and the hood, the paint mist will not leak out to the outside and will not pollute the atmosphere or adhere to peripheral equipment. be. In addition, the reciprocating drive device that drives the painting gun back and forth is not located inside the hood, but the main part is provided in the air blowing part outside the hood, and the holding member that holds the painting gun is protruded from the side wall opening of the air blowing part for painting. Since the gun is driven reciprocatingly, paint mist does not enter the air blowing section, and no paint mist adheres to the reciprocating drive unit, especially the reciprocating drive unit, making it easy to perform maintenance such as removing paint mist. is completely unnecessary.

In the above embodiment, the reciprocating drive device is disposed on the side surface of the hood, but it can also be disposed on the rear surface.Also, the entire reciprocating drive device including the drive source can be installed inside the air blowing section. Alternatively, it can be arranged in the air blowing part so that only the holding member protrudes inward of the hood through the air blowing part.

In addition, apply appropriate measures such as pasting a sealing member such as a rubber seal to the narrow groove-shaped opening for protruding the holding member to prevent air from blowing out from the narrow groove-shaped opening into the hood as much as possible. It is also possible.

In addition, in the above embodiment, the coating device is applied to the exterior of a ship by moving it relative to the surface to be coated, but it can also be applied to coating the exterior surfaces of tanks, etc., and the coating device can also be fixed. It can also be applied to a device that moves the surface to be coated or both of them as appropriate.

As described above, with the present invention, even if there is a certain gap between the surface to be painted and the coating device, the paint mist can be reliably prevented from flowing out through the gap, thereby preventing air pollution. This prevents paint mist from adhering to peripheral equipment, etc., and prevents paint mist from adhering to the reciprocating drive part of the reciprocating drive device, even though the paint gun is reciprocated within the hood and the paint mist is sucked out. It is easy to use and does not require maintenance such as removing paint mist from the reciprocating drive unit.
