Abstract

PURPOSE:To apply painting to a corrugated object to be painted without loss, in an apparatus for painting a paint supplied to a roll brush by scattering the same, by changing the shape of a paint supply roll corresponding to the corrugated shape of the object to be painted. CONSTITUTION:To one roll 8 among a pair of paint supply rolls 7, 8, grooves 13 corresponded to the corrugation of a body 6 to be painted are formed and a paint 10 is supplied between this paint supply rolls 7, 8. The paint supplied in corresponding relation to the corrugated shape of the body 6 to be painted is supplied on a roll brush 1. The rotating roll brush 1 is contacted with a barrier plate 12 and the paint is scattered by the repelling force of the roll brush 1 to apply painting on the corrugated board to be painted uniformly.

Cement roof tiles have traditionally been made thicker and have a surface that alternates between corrugated and flat parts in order to give a sense of grandeur and grandeur. In order to impart aesthetic appeal and durability, an inorganic coloring composition (paint) is applied to the surface of a cement tile excipient and cured during the production stage of cement tiles.

This painting is done by applying paint to the cement tile shaped body using a mortar gun or roll brush, but when using a mortar gun, there is a lot of paint scattering and loss, and in addition, the mortar gun is easily visible. Because of the problem of easy clogging, a method using a roll brush is generally adopted industrially. When painting with a roll brush in this way, the paint is sprayed off by the repulsive force of the roll brush bristles that bend when they hit the flat baffle plate, so the paint is applied in the direction of the repulsion of the bristles, that is, the cement. It is splashed toward the surface of the shaped body for roof tiles. In this case, uniform coating can be achieved if the surface of the shaped body is flat.

However, if the surface of the shaped body has a shape in which corrugated parts and flat parts appear alternately, the surface type of the shaped body with the unit length of the baffle plate is flat. Since the slope of the corrugated part is larger than the slope of the corrugated part, even if the same amount of paint is splashed, the amount of paint per unit area of the slope of the corrugated part is smaller than that of the flat part, resulting in uniform coating. The problem was that it became impossible to achieve this goal.

The present invention was made in view of the above circumstances, and includes a roll brush having a large number of bristles on its outer peripheral surface, a driving means for rotationally driving the roll brush, and a drive means for rotating the roll brush from between the rolls. a pair of supply rolls that rotate in opposite directions so as to flow down a fixed amount of paint; and a baffle plate that is positioned parallel to the axial direction of the roll brush and is disposed so that its lower edge contacts the bristles of the roll brush. This is a coating device that uses the repulsive force of the bristles of the roll brush that bend against the tip of the baffle plate as the roll brush rotates to spray paint supplied to the roll brush onto the object to be coated. The gist of the coating device is that one of the supply rolls has grooves formed in the circumferential direction in a portion corresponding to the sloped surface of the curved portion of the surface of the object to be coated. It is.

By doing this, the amount of paint splashed onto the sloped portions of the corrugated portions increases, so that the amount of coating on the unit surface 11 becomes almost the same as that on the flat portions, making it possible to achieve uniform coating.

In the figure, 1 is a roll brush, and this roll brush 1 is constructed by having a large number of bristles uniformly planted radially on the surface of a roll 2. A force/(-5) is attached to the outer periphery of this roll brush l, which forms an upper paint inflow part 8 and a side paint projection part 4. A cement tile shaped body having alternating corrugated parts 6' and flat parts 6b on the surface (Fig. 2)
It is disposed so as to be perpendicular to the transfer direction (arrow entry direction) of No. 6, and is rotated by a motor (not shown). A guide plate 9 is provided at the upper paint inflow portion 8 of the cover 56.
A pair of supply rolls 7 are provided above the guide plate 9.
.. 8 are provided so that their axial directions are aligned with the axial direction of the roll brush I, and are rotated in opposite directions with a constant gap maintained so that the paint lO flows down from between the rolls 7.8.

On the upper side of this pair of supply rolls 7.8, the supply roll 7.
.. A paint tank 11 for supplying paint 10 is provided between 8 and 8. At the upper edge of the side paint projection part 4 of the cover 5,
A baffle plate 12 is provided (the baffle plate 12 is parallel to the roll brush l), and its lower edge is oriented in the axial direction of the roll brush l. The tip of the bristles of the roll brush l hits this lower edge, and the repulsive force causes the paint lO that has flowed down on the roll brush l to be splashed toward the surface of the cement tile excipient 60. There is. Of the pair of supply rolls 7.8, one of the rolls 7 has a circular shape as shown in FIG. 8 (in FIG. 8, one roll 7 is drawn below the other roll 8 for convenience of illustration). Although the other roll 8 has a columnar shape, a groove 18 is formed in the circumferential direction in a part corresponding to the slope part of the corrugated part 6a of the cement tile shaped body 6, and the gap between the rolls 7.8 is formed in this part. It is set so that the amount of paint flowing down to the sloped part of the corrugated part 6a of the cement tile shaped body 6 is larger than that to the flat part 6b, and the amount of paint is set to be almost uniform throughout. . In this case, the rotational speed of one roll 70 is set higher than the rotational speed of the other roll 80, and the paint lO supplied from the paint tank 11 is transferred to one roll 7 and then flows down onto the roll brush 1. It's becoming like that. In addition, in FIG. 1, 14 is a paint supply pipe;
Reference numeral 5 denotes a paint layer on the surface of the shaped body 6 for cement tiles, 16 a receiving mold, and 17 a conveyor for transporting the receiving mold 16.

With this configuration, the paint 10 supplied from the paint tank 11 to the pair of supply rolls 7.8 is transferred from between the pair of supply rolls 7.8 to the slope of the corrugated portion 6a of the shaped body 6 for cement tiles. The coating amount per unit area is adjusted to be equal to the flat part 6b and the flat part 6b, and flows down onto the roll brush 1. Therefore, it is maintained in that state by the roll brush 1 and applied to the surface of the cement tile shaped body 60, thereby achieving uniform coating.

Next, an example of coating a cement tile shaped body using the apparatus of the above embodiment will be described. A mixture of 95 parts by weight of ordinary cement, 6 parts by weight of pigment, and 50 parts by weight of water was used as a mixture for manufacturing excipients for cement tiles. We created a shaped body for cement tiles. The coating thickness of the paint on the surface of this cement tile shaped body was 0.41 using the coating device shown in Figure 1.
1! I applied paint to make it look like I. At this time, the diameter of the roll brush l was set to 800 m, and a pair of o-luers were used.

The diameter of 8 was set to 100W. Then, the number of rotations of one roll 7 of the pair of supply rolls 7.8 is 2Q
rpm, and the other roll (with #I) 80 rotation speed was set to IQ rpm. As a result of painting in this manner, the paint was applied almost uniformly to both the sloped parts of the corrugated parts and the flat parts of the shaped body for cement tiles in a thickness range of 0.85 to 0.40 m. In the case of painting, the number of painting mistakes was extremely reduced.

In addition, in the apparatus of the above embodiment, by changing the interval or rotational speed of the pair of supply rolls 7.8, it is possible to change the amount of paint flowing down to the roll brush 1, thereby changing the coating thickness of the paint.

また、一方のロール7の回転数は、塗料10の流下が円

Further, the rotation speed of one roll 7 does not need to be faster than the other roll as long as the paint 10 flows down smoothly.

Since the coating apparatus of the present invention is configured as described above, problems such as a large amount of paint scattering loss and mortar gun clogging can be avoided when painting objects that have corrugations or valleys on the surface. Uniform surface coating can be achieved without causing any stains.
