Description

[Detailed explanation of the invention] This invention uses a reciprocating coating device (reciprocator) to paint the surface while conveying multiple objects to be painted, such as three-dimensional tiles, side by side on a wide conveyor (slat conveyor, etc.). This relates to a device for carrying out this process.

When tiles are painted on a wide conveyor, they are usually layered one on top of the other in the same way as they are on a roof, but because the surface is three-dimensional, it is difficult to paint from only one direction. This makes it difficult to uniformly coat the entire surface.

Therefore, two or more paint guns are usually used, each spraying paint from different angles to prevent shading on the painted surface.

This invention attempts to eliminate the above-mentioned drawbacks by using only one painting gun and changing the direction in which the gun faces on the outward and return journeys.

This invention is based on a reciprocating painting device in which a paint spray gun 3 is attached to a floating plate 2 that horizontally reciprocates between rails 1 and 1' in the form of a rack. It is pivoted to the floating plate 2 at a certain fulcrum 5, and the paint injection gun 3 is attached downward to the tip of the gun holding arm, and the base end of the paint injection gun holding arm 4 is attached so that the paint injection gun 3 always faces in an oblique direction. A spring 9 is stretched between the part and the floating plate 2, and both ends of the reciprocating stroke of the floating plate 2 are in contact with the gun holding arm, so that the tip of the gun holding arm resists the biasing force of the spring. direction changing mechanisms 6 and 6' are respectively provided to rotate the paint spray gun in an oblique direction opposite to the previous one, and the direction in which the tip of the paint spray gun holding arm is directed is different between the forward and return paths of the floating plate 2. This relates to a surface coating device for roof tiles.

The present coating apparatus will be described in detail below based on one embodiment.

The drawing shows one embodiment of this system, in which the horizontal reciprocating movement of the floating plate 2 is performed by an endless chain 7.

It should be noted that this horizontal reciprocating motion can also be achieved by a piston or other method.

In the figure, reference numeral 8 indicates a rod-shaped attachment attached to a part of the endless chain 7, and a spring 9 is for fixing and holding the gun holding arm 4 in an oblique direction at all times. Even if used, the gun holding arm 4 can be held fixed and the direction can be changed at both ends.

Further, 10 is a conveyor such as a slat conveyor, and 11 is a roof tile.

In the apparatus shown in this drawing, the floating plate 2 is first moved to one end and then painted while being sequentially slid in the lateral direction.For ease of understanding, this will be explained with reference to the drawing.

That is, in FIG. 1, the floating plate 2 is moved to the left end (in this state, the tip of the gun holding arm 4 is directed to the right by the direction changing mechanism 6), and when the paint is ejected, it hits the left end of the tile 11. applied.

Next, the application is applied while moving the floating plate 2 itself to the right, and when it reaches the right end, the right direction changing mechanism 6'
is in a state of pushing the holding arm 4, so the direction of the holding arm 4 is changed around the fulcrum 5, and the injection gun 3 now faces to the left, so that the right end of the roof tile is also coated.

Note that since the roof tiles 11 are sequentially transported by the transporter 10 in a direction perpendicular to the sliding direction of the floating plate 2, the coating work can be performed continuously.

According to this invention, homogeneous coating can be applied to any surface of tiles with three-dimensional surfaces, such as sleeve tiles and eaves tiles, using a single spray gun, and the spray gun automatically directs the coating. In addition to being switchable, the holding arm is stabilized in an oblique direction by the spring in the middle of the switch, which has the effect of ensuring reliable application.

Note that this coating device can be widely applied not only to roof tiles but also to coating materials whose ground surface has a three-dimensional shape.
