Abstract

PURPOSE:To easily coat the one surface and side surface of a plateshaped body by passing the body with the surface to be treated directed downward and the height of the upper surface made almost equal to the coating blowing-up height through a coating device for blowing the coating up to an almost uniform height in the form of a shower or a curtain. CONSTITUTION:The coating 4 is blown up to an almost uniform height by the coating device 3 in the form of a shower or a curtain. The upper surface 7 of the plate-shaped body 1 is positioned almost at the height of the blown-up coating 4, and the body 1 is passed through the coating device. When the body 1 passes through the position of the blown-up coating 4, the side surface of the body 1 is coated, then the lower surface is coated, and further the rear side surface is coated. In this case, when the width of the blown-up coating 4 is made larger than that of the body 1, the side surface in the traveling direction of the body 1 is also coated. Even the rugged side surface can be coated without hindrance, the blown-up coating 4 is not brought into contact with the upper surface 7, and the surplus coating is not dropped onto the upper surface 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for coating a plate-shaped body, and allows one side and side surfaces of the plate-shaped body to be easily coated.

(Prior Art) Conventionally, as a method for coating a plate-like object of this type, a method is known in which the plate-like object to be coated is coated by passing the paint falling in a curtain shape under the plate-like object.

Also known is a method of overlaying a plate-like body in which the flat and side surfaces of the plate-like body are coated with a roll.

(The problem that @Ming is trying to solve) Among the things described in the conventional technology, in the former method,
Although K is suitable for painting the surface of an object having a curved or uneven surface, it is not suitable for painting only one side or a side surface of a plate-shaped object. That is, even if the plate-like object is horizontally passed under the paint falling like a curtain, the paint falling on the top surface will flow down from the side, and in this case, the paint will cover the surface 11 and some paint will also be on the back side. The cinema was especially appropriate.

Furthermore, in the latter method, many types of rolls are required for coating the side surfaces, and when the side surfaces are uneven, it is difficult to apply the coating using rolls.

The present invention has been made in view of these problems in the prior art, and its purpose is to provide a method for coating a plate-like body that can easily paint only one side and side surfaces of the plate-like body. It is about providing.

(Means for Solving the Problems) The method for painting a plate-like body of the present invention is a method for painting a plate-like body in which one side and side parts of the plate-like body are coated. A coating device that sprays paint is installed at a height, and the plate is transferred onto the coating device with one side to be coated facing downward, and the top surface of the plate is almost aligned with the height of the coating device. , which is characterized by being allowed to pass through.

(5ili! Example) In FIGS. 1 and 2, l is a plate-shaped body, 2 is a roller, and 3 is a coating device.

The plate-like body l is, for example, a cement board, plywood, etc., and the product is a cement board, a flat roofing material, an exterior material, etc. Flat roofing materials, exterior materials, etc. are painted for waterproofing or cosmetic purposes. The roller 2 is for transporting, and other means may be used to transport the plate-like body l. The coating device 3 sprays the paint 4 upward in a shower-like or curtain-like manner. In this case, the height of the shower-like or curtain-like spray is almost constant. In other words, there is not much difference in the height of the paint being blown up. In this coating device 3, a paint blowing device 6 is housed in a paint container 5, and out of the blown paint 4, that which does not adhere to the plate-like body 1 enters the paint container 5 and can be used repeatedly.

In order to coat the plate-like body 1 with this coating device 3, as shown in FIGS. It is made to pass through the plate-shaped body 1. When the plate-like body 1 passes through a position where the paint 4 is blown up in a shower or curtain-like manner, the side surfaces of the plate-like body 1 are first exposed to the paint 4, and the sides are coated with the paint 4. As the plate-shaped body 1 advances further, the blown-up paint 4 hits the lower surface of the plate-shaped body 1, and as the plate-shaped body 1 advances further, the blown-up paint 4 hits the rear end side surface of the plate-shaped body 1. In this case, if the width of the paint 4 that is blown up along the traveling direction of the plate-shaped body 1 is made wider than the width of the plate-shaped body 1, the blown-up paint will hit the side of the plate-shaped body 1 in the same way and can be painted, and even if the side surface is uneven. It can be painted without any problem.

However, the blown-up paint 4 does not hit the upper surface 7 of the plate-like body l, and even when excess paint falls, the paint does not cover the upper surface 7.

That is, since the upper surface 7 of the plate-like body 1 is almost the same as the height of the blown-up paint 4, the paint 4 increases as the plate-like body l advances.
However, it does not remain on the upper surface 7.

(Effects of the Invention) Since the coating method for a plate-like body of the present invention is configured as described above, one side, which is the bottom surface of the plate-like body, is coated without the paint being applied to the top surface, and at the same time, the side surface is coated. It can also be painted.

Claims (1)

[Claims] (1) In a method of painting a plate-shaped body in which one side and one side of the plate-shaped body are coated, a coating device is installed that sprays paint at a substantially constant height in a shower-like or curtain-like manner, and the paint is sprayed onto the coating device. A method for coating a plate-shaped object, characterized in that the plate-shaped object is transported and passed with one side to be coated facing downward and the upper surface of the plate-shaped object substantially aligned with the paint blowing height of the coating device.
