Next, a method for coating a building panel according to the present invention will be described. The coating method of the building panel of the present invention uses the multi-color coating roller coating apparatus as described above, and supplies a different color paint to each coating chamber of the multi-color coating roller to coat the coating surface of the building panel. Is what you do. Specifically, for example, the building panel is left standing with the surface to be painted facing upward, and the paint chambers 3, 4, and 5 shown in FIG. 2 have different colors of paint, for example, similar colors, A light paint is supplied to the paint chamber 3, a dark paint is supplied to the paint chamber 5, and a paint having an intermediate brightness is supplied to the paint chamber 4. The roller is brought into contact with the surface of the building panel to be painted. Paint by rolling. The traveling direction of the roller is appropriately selected such as a direction perpendicular to the long side direction or the short side direction with respect to the building panel, or a direction crossing obliquely at a predetermined angle. As a result, the paint discharged from the multicolor coating roller is partially mixed, so that the building panel can be easily painted with different colors and colors depending on the portion. As for the coating, in addition to the pre-coating for each panel as described above, it is also possible to perform the coating using the multicolor coating roller coating device after the building panel is attached to the building.

Furthermore, not only is the coating applied once, but also in a state where the coating is not dried, the panel is slightly shifted or the roller is slightly shifted in the direction of the fixed axis.
Overcoating may be performed by continuously performing the movement of the panel and the orthogonal movement of the coating roller. Due to the mixing and overlapping of colors at the borders of each color inside the paint tool and on the painted surface,
A variety of paintings such as aged brick spots and blur patterns are possible.

Specifically, the following method can be considered as a method for coating a building panel according to the present invention. As described above, paints of different colors are supplied to each paint chamber of the multicolor coating roller, and while moving the building panel, the multicolor coating roller is flush with the building panel moving surface and orthogonal to the building panel moving direction. In the case of painting by moving back and forth obliquely or obliquely at a predetermined angle, for example, moving the building panel at a constant speed and moving the roller on the same plane as the building panel moving surface in the direction perpendicular to the building panel moving direction by the width dimension of the building panel Paint by reciprocating at a constant speed. In this case, the painted surface is in a state of being repeatedly applied at a constant interval in a direction opposite to the moving direction of the building panel by the V-shaped locus due to the roller width, and changes the ratio of the moving speed of the building panel to the reciprocating speed of the roller. This makes it possible to change the coating rate and the number of times of coating.
Since both the building panel and the painting roller are moved at a constant speed for painting, automatic painting can be performed.

FIG. 3 shows an example of a multicolor coating roller coating apparatus used in such a method of coating a building panel. In this apparatus, the multicolor coating roller is reciprocated in the direction perpendicular to the building panel moving direction on the same plane as the building panel moving surface for painting.

The multi-color coating roller coating device 30 includes a roller vertical movement mechanism for moving the multi-color coating roller 10 in the vertical direction, and a roller horizontal movement for moving the multi-color coating roller 10 in the horizontal direction. Mechanism and
A multicolor paint supply mechanism for supplying a multicolor paint to the multicolor coating roller 10 is provided. Although the multicolor paint supply mechanism is not shown in FIG. 3, the multicolor paint supply mechanism includes a paint tank and a pump connected to each of the paint supply pipes as shown in FIG. Is used.

In this multi-color coating roller coating apparatus 30,
Four supporting legs 31 and 32 (only two of them are shown in the drawing) and beam members 33 and 34 (shown in the drawing) fixed on the supporting legs so as to connect the upper ends of the supporting legs respectively. Of these, only two of them appear), forming a multicolor coating roller holding mechanism. A so-called linear guide 35 is fixed on one beam member 33, and a ball screw 36 arranged in parallel with the linear guide 35 is provided on the other beam member 34. The linear guide 35 includes a guide rail 35a and a slider 35b that moves on the guide rail 35a. The ball screw 36 includes a screw shaft 36a and a moving nut 36b that is moved by the rotation of the screw shaft 36a. Then, the slider 35 of the linear guide 35
The upper surface of the moving nut 36b and the upper surface of the moving nut 36b of the ball screw 36 are at the same level, and a work table 37 is installed between the two. And the work table 37
Is provided with a hydraulic or pneumatic cylinder 38. A roller holding member 40 is fixed to the lower end of a vertically driven piston rod 39 provided in the cylinder 38, and the cylindrical fixed shaft 2 of the roller 10 rotates on side frames 41 and 42 of the roller holding member 40. It is improperly mounted. A cylinder 38 attached to the work table 37 constitutes a roller vertical movement mechanism.

A motor mounting bracket 44 having a fixing member 43 attached to the lower surface is fixed to the upper part of the support leg 32 on the side where the ball screw 36 is provided.
A motor 45 is mounted on the motor mounting bracket 44. The drive shaft 45a of the motor 45 is
The ball screw 36 is fixed to one end of a screw shaft 36a via a coupler (not shown). The other end of the screw shaft 36a of the ball screw 36 is rotatably supported by a bearing (not shown) mounted on a support leg (not shown). The rotation of the drive shaft 45a by the operation of the motor 45 rotates the screw shaft 36a, and the rotation causes the drive nut 36b of the ball screw 36 to move in the horizontal direction. Therefore, the work table 37 fixed to the drive nut 36b and the slider 35b of the linear guide 35 also move in the horizontal direction. The work table 37 is, for example, a motor 4
5 in the forward direction by rotation of the motor 5 in the forward direction.
The rotation in the reverse direction of 5 moves the front side of the drawing. Thus, a roller horizontal movement mechanism is configured to move the multicolor coating roller 10 in the horizontal direction. On the side of the linear guide, a storage part 47 for a paint supply pipe 46 having a predetermined length formed by a flexible pipe is formed.
A belt 48 of a conveyor device for moving building panels is provided so as to pass through the roller coating device 30.

The convex portion (convex surface) 51 has a brick or tiled surface pattern and the concave portion 52 has a brick or tiled joint pattern. And the building panel 50
As shown in FIG. 4, the joint surface is painted in advance with the joint color and dried on the belt 48 and moved in the direction of arrow A. Then, in a state where the multicolor coating roller descends and comes into contact with the convex surface 51 of the building panel 50, the roller reciprocates in the direction of arrow B (in this case, the direction flush with the building panel moving surface and orthogonal to the building panel moving direction). Since the roller 10 is pressed against the painted surface of the building panel 50, the roller 10 is rotated by this movement.

Then, by adjusting the moving speed of the building panel 50 and the moving speed of the multicolor coating roller 10, a part of each convex surface 51 of the building panel 50 or each convex surface 51 is adjusted.
Can be applied over the entire surface. in this way,
By using a multi-color coating roller to apply the paint before the paint dries, as shown in FIG. 5, the joint color is left in the concave portion, and the mixed color of different colors also occurs on the surface of the convex portion, resulting in irregularities. It is possible to manufacture the building panel 60 having the multicolor painted surface 53 whose color and color tone have been changed in a stepless manner and which cannot be performed by painting with a normal roller or spraying. In particular, by using similar paints of a similar color, a light paint and a dark paint, and a paint having an intermediate brightness between the two, the color and color tone changed irregularly and / or steplessly, and the color changed over time. An architectural panel having a painted surface with a solid feeling like a brick can be obtained. FIG. 6 shows FIG.
FIG. 2 is a diagram schematically showing a cross section of the building panel shown in FIG. On the convex surface of the building panel, a multicolored coating surface 53 is formed irregularly and / or steplessly, and the joint coating layer 54 is left in the concave portion 52 and appears.

By changing the diameter of the coating roller, the joint coating depth (apparent thickness of brick or tile) can be obtained.
Can be changed. Further, the convex surface other than the joint portion is not limited to a flat surface, but can be painted in a state where the brick is weathered by applying fine irregularities with a paint.
