Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a heavily used roller coater has such defects that a coating infiltrated in a roller is dripped, and the coating is scattered over a wide range with fine particles due to the centrifugal force of the rotation, because the coating uses the rotation of the roller, and in order to prevent these defects, the coating work must be carried out after applying careful curing to the wide range, as a result, much labor and cost are needed, and after the completion of the coating, most of curing materials become refuse to be damped, or the problem that this is a coating method of the combination of a brush, or the like, because the roller has a circular shape and cannot coat corner parts, or the like. <P>SOLUTION: The coater has two rollers, and the upper roller has the function of coating, and the lower roller has functions of uniformizing the coating surface and preventing the dripping. Furthermore, the two rollers are fitted with covers to prevent the scattering, and the tip of the cover is made operable to press against a coating impossible part, thereby the roller and a felt-like part are crimped to be deformed, as a result, the coating with one single tool without curing is made possible. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention is a coating machine that eliminates the disadvantages of scattering by the centrifugal force of the rotation of a conventional roller coating machine, dropping of paint, and the corner being unable to be painted with a roller.

  Rolling is the most commonly used means of painting by professional painters and also for DIY carpentry amateurs. However, it is general that the conventional type roller is scattered by the centrifugal force due to its rotation, and the dropping of the roller from the roller in which the paint has penetrated always occurs. In addition, the painting with a conventional roller cannot be applied to the entire width and height of the four corners of the entire painting surface, and the ventilation fan and other parts, and painting using another brush is generally performed.

Problems to be solved by the invention

  Scattering due to centrifugal force due to the rotation of the roller covers a wide range of floors, furniture, and various appliances, and the paint that has splashed mercilessly onto the hair, face, hands, and arms of the person performing the painting work. This is an unavoidable event that the paint is scattered by centrifugal force as long as the rotation of the roller is used.

  Most of the painted surface is uneven. In order to make sure that the paint adheres to the bottom of the recess, it is necessary to press the roller. At that time, it is a common occurrence that the paint that has penetrated into the roller drops and stains the floor.

  The roller is always circular. For this reason, even if it is cured, the walls and ceiling borders and various appliances cannot be painted at the corners of the corners, and other parts such as brushes must be used. There is a difference in how and how the paint is applied between the roller and the brush, which requires technology and tends to cause uneven coating.

  For the reasons mentioned above, painting is done with a roller that finishes relatively quickly and neatly, but it is not possible to complete painting work without careful curing.

  The present invention solves all of the above-mentioned drawbacks, and even for amateurs, roller coating is relatively easy, quick, no dirt, no dirt, almost no curing, regardless of wall or ceiling. The machine is provided.

Means for solving the problem

  The roller coating machine made with this new concept has two rollers at regular intervals parallel to the top and bottom, the upper roller has the function of penetrating and adhering ordinary paint, and the lower roller is coated It has the role of receiving paint that drops off from the upper roller and attaching it to the painted surface, and the role of following and smoothing after the upper roller has been applied. By having two rollers, it is possible to prevent falling off and to make a beautiful and stable coating surface in almost half of the reciprocating process, which is usually a reciprocating process several times.

  Of the two rollers, the upper roller is optimally formed by wrapping a permeable fiber with a hairline of about 3 mm around the surface of the sponge roller or sponge roller. In other words, a roller with elasticity is optimal. The lower roller is compatible with all commercially available paint rollers. Cover all parts of the two rollers that do not face the painted surface with a trapezoidal cover when viewed from the side of the rollers. The front end of the cover is actuated and a felt-like thing with elasticity and water retention is attached to the end of the operating part. Then, for example, by pressing the working part at the front end against the unpaintable part such as a window frame, the felt-like part and the upper roller part are deformed and become flat with respect to the painted surface, and the roller part is stained. The paint that comes out moves to the felt part instantly, and painting at the time becomes possible without curing.

  Normally, the roller is pressed against the painted surface during painting. Therefore, for example, when painting a wall surface, the gap between the wall and the bottom of the cover is about 5 mm, and the cover can completely prevent scattering when the roller rotates. In addition, when the ceiling is painted, the cover receives the roller from below, so it is possible to completely prevent the dropping and splashing.

  Most of the rollers are used by reciprocating up and down. However, in some cases, it may be used by reciprocating horizontally. Even in this case, even if the paint splashed from the roller accumulates in the cover to some extent, if it exceeds the allowable range, it adheres to the lower roller and is applied to the painted surface. In addition, except for the operating part, the cover end 3 is formed in a bag shape at the part facing the painted surface of the cover, so that it does not spill from the cover even if it is used sideways.

  At the time of painting, only about 5 mm is applied to the painted surface from the felt-like part, and the rest is painted by rotating the roller, so the difference in the finished surface of the painted surface due to the difference in tools can be visually confirmed There will be a beautiful finish.

  First, the painting process will be described in the order shown in the figure. First, paint is applied from the dish-like paint tray to the upper roller in FIG. FIG. 1 (B) is a drawing in which the paint is applied to the wall, but it is general that the roller is pressure-bonded to the paint surface in this way. At this time, the paint leaked from the upper roller is absorbed by the lower roller, and when the paint absorbed by the lower roller exceeds the allowable limit, it is also applied to the painted surface from the lower roller. In addition, paint that has been scattered mainly from the upper roller, rarely from the lower roller, is completely contained in the trapezoidal cover and does not adhere to the unpaintable part.

  In general, most of the parts that cannot be painted regardless of the ceiling, walls, etc., protrude from the painted surface. When painting these protruding parts, the upper roller and felt-like parts are pressed against each other and deformed by pressing the cover tip as shown in Fig. 2 (C), and pressure on the paint surface is also applied. It becomes flat and paint oozes out from the upper roller, and the paint surface is instantly applied from the felt-like part by capillary action and pressure. In addition, the paint-impossible part and the front end of the cover are not in contact with each other, and only the most advanced part is in close contact with the line.

  As described above, all the disadvantages of the conventional roller coating machine were solved, and it was possible to quickly and cleanly apply the coating without the need for curing and to prevent it from becoming dirty and not dirty.
