Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coating apparatus for plate materials, and more particularly to a coating apparatus for plate materials useful for painting partial spots on a plate material.

BACKGROUND OF THE INVENTION In the case of architectural board materials, flat roofing materials, and the like, especially fiber-reinforced inorganic board materials, surface coating is performed for the purpose of imparting water resistance. As this coating method, a spray method or a flow coater method is widely used as an industrial coating method.

Problems with the Prior Art The doffing coating method is generally suitable for applying uniform coating to the surface of a board, but when painting partial spots on the surface of a board, such as two-tone painting, for example, There are problems such as difficulty in application. For example, as shown in Figure 6, in the case of flat roofing materials, after applying a primer coat to the surface, a waterproof coating is applied again to the surface, but this waterproof coating is applied as shown by diagonal lines. , if it is applied only to the exposed surface A' of the roofing material A, it will be enough. However, the contour of this exposed surface A' has various shapes depending on the shape of the lower edge AI of the roofing material A, and such a contour shape cannot be painted without auxiliary means such as masking. SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide an apparatus that can coat surfaces with complex contours in a streamlined manner without requiring any auxiliary means.

In other words, the plate coating apparatus of the present invention includes a guide chute that delivers the plate in a flat state, receives the plate discharged from the guide chute, and transfers the plate to the lower surface of the guide chute in the flat state. - a transfer device comprising a receiving member that can be reciprocated to push back the material; a conveyor provided on the lower surface of the guide chute for taking out and transferring the pushed back board material; and an upper portion between the receiving member and the end of the conveyor. The present invention is characterized by being comprised of a painting device comprising an upright screen board and a spray nozzle that uniformly sprays paint onto the screen board and flows the paint uniformly down the lower edge of the screen board. It is something.

explanation The present invention will be explained below using examples.

Figure 1 is a side view of an embodiment of this invention, Figure 2 is a plan view of Figure 1, and Figures 3 (a) and (b) are side views showing the overall configuration of an embodiment of this invention. be.

The coating device 1 for plate materials of the present invention includes a guide shoe 10 that brings out a sheet material such as a wall board or a flat roofing material in a flat state.
A receiving member 12 is configured to receive the plate material A discharged from the guide chute O and push the plate material A back toward the lower surface of the guide chute 10 in a flat state. A transfer device 1' consisting of a conveyor 13 provided on the lower surface of the guide shoe 10 for taking out and conveying the plate material A, a receiving member 12, an end portion of the conveyor 13, and 9 approximately midway between the conveyor 13 and the guide shoe 10. Top surface 1
Almost vertically installed.

The paint 16'3 is uniformly sprayed and supplied to the screen plate 15 and the screen plate 15, and the paint 16 is applied to the lower edge 15A of the screen plate.
The spray nozzle 17 uniformly flows down the coating device L. In addition, 14 in the figure is a receiving plate.

In the above, as a means for continuously supplying the plate material A to the guide chute 10, a slide guide plate 20 is connected to the guide shoe 10, as shown in FIG. Either a line system in which the sheets carried by the conveyor 21 are supplied by falling, or a line system in which the transfer conveyor 22 is directly connected to the guide chute 10 as shown in FIG. 3 (b). can also be adopted. These are appropriately selected depending on the arrangement of other incidental equipment and flow lines.

Reference numeral 18 in FIG. 1 denotes an air knife, which is provided to remove, by spraying, excess paint on the top surface of the plate A transferred by the take-out conveyor 13, and is installed as necessary.

In addition, in the above embodiment, the guide shoe 10 has an end 10A on the side where the plate material A is sent out, which has a rear end contour A2 of the plate material A.
After being cut and aligned along the guide shoe 10, the plate material A is configured to fall downward from the guide shoe 10 in an upward plane position, as will be described later.

action Next, the operation of the embodiment of this invention will be explained.

First, the paint 16 is ejected from the spray nozzle, and the paint 16 falls as a uniform film from the lower edge of the screen plate 15. In this state, one guide shoe (10) and one plate material receiving member 12 Supply direction. The board member is the receiving member 12
advance across the coating of paint 16 until it is received by the
Eventually, it falls from the end of the guide chute 10 while maintaining a horizontal posture, and is then pushed back toward the take-out conveyor 13 by the receiving member 12.
It is then transferred to the next process.

At this time, the coating film of paint 16 continues to fall,
Since the plate material A crossing this coating film is pushed back by the receiving member 12 at a certain position, the coating material 16
The coating is applied twice as indicated by arrows X and Y, with the boundary surface being approximately the midpoint P between the receiving member 12 and the end of the take-out conveyor 13.

Therefore, partial painting becomes possible through continuous work.

At this time, if the shape of the lower edge of the screen plate 15 is formed in a zigzag shape as shown in FIG. 5, the paint 16 will form a coating film in this shape and fall. It is also possible to perform partial coatings with complex outlines as shown.

In addition, although the above explained the painting of flat roofing materials, it can be applied in the same way even when painting wall materials with other shapes and colors with complex contours on the surface to add patterns. Needless to say, you will get it.

Effects Since the present invention is constructed as described above, it is possible to paint colors continuously without using any auxiliary means such as masking, and the paint is allowed to fall along the screen board. By making the shape of this screen plate into the shape of the seed λ, it is possible to paint any color of the outline shape.
