Description

Paint gun position and angle control device {APPARATUS FOR CONTROLLING ANGLE AND POSITION OF SPRAY GUN OF PAINTING SYSTEM}

The present invention relates to a painting gun position and angle adjustment device.

In general, the painting work on new ships is to prevent corrosion and contamination of the hull by sea water, and in particular, the painting on a large ship is to make the preceding block of each hull manufactured in block units (that is, to form the hull of a large ship). The hull block, which is manufactured in advance in units of a plurality of blocks, is referred to as a preceding block) and is divided into an outer coating and an inner coating.

The outer coating is a coating on the outer plate of the preceding block, and proceeds by dividing the painting work on the lower, side and top of the outer plate.

During the painting work on the outer plate of such a preceding block, in particular, the side painting work of the preceding block is a work performed at high altitudes, and a painter and a high-altitude driver usually work in pairs on a high-rise vehicle.

That is, with the painter and the driver riding in the basket of the car, the painter paints the outer plate of the preceding block using a single paint gun, and the driver drives the car to the next position to be painted at the speed of work. Done.

By the way, the side coating work on the outer plate of the conventional preceding block acts as an important factor to determine the coating quality, such as the coating speed using the coating gun, the coating distance of the coating gun to the surface to be coated, and the spraying pressure of the paint through the coating gun. However, due to the nature of manual work, it has been practically dependent only on the skill and experience of the painter.

Recently, due to the trend of automation and the development of coating equipment, automation equipment such as robot equipment for painting based on high-rise vehicles has been researched and developed, and workers do not need to ride directly on high-rise vehicles to perform painting work on the ground. The automatic painting system that performs automatically is a trend.

However, even in the case of such automatic painting system, a sufficient working space for painting work is required around the outer plate of the preceding block, and the disadvantage that the road surface condition or other external environment of the painting factory acts as a determinant of painting quality still remains. .
