JP4729466B2 - Patterning roller and pattern forming method using this roller - Google Patents

Description

  The present invention provides a roller for forming a new pattern on the outer wall, inner wall, ceiling, floor surface, etc. of a building, or forming a pattern on a building material surface used for those parts, and a pattern using the roller. The present invention relates to a forming method.

  Various methods for directly forming a pattern having irregularities on the outer wall, inner wall, ceiling, floor surface, etc. of a building using a coating material have been proposed and implemented. These methods can be broadly classified into those that form a pattern by painting (including spraying), those that form a pattern using a roller, those that form a pattern using scissors, and combinations of these. In addition, depending on the literature, a roller including a pattern forming portion, a handle as another portion, a support shaft of the roller, and the like may be simply referred to as a roller.

  Among these pattern forming methods, there is a technique disclosed in, for example, Japanese Patent Application Laid-Open No. 60-241971 and Japanese Patent Application Laid-Open No. 2002-317551 by the present applicant. Moreover, design registration No. 728172 was in the design of the roller cover for forming a pattern.

Japanese Patent Application Laid-Open No. 60-241971, which is shown as Patent Document 1, has a pattern in which protrusions parallel to the roller surface are provided, and the coating material is familiarized over the entire surface of the roller to show a plurality of parallel or a plurality of sine curves on the coated surface Was formed.
Japanese Patent Laid-Open No. 60-241971 (FIGS. 1 and 2)

In JP-A-2002-317551 shown as Patent Document 2, a parallel projection formed on the roller surface is first applied to a surface to be coated and the coating material is in an undried state. By pressing down the strip, it was possible to make use of the pressed surface and the surface pattern before pressing.
JP 2002-317551 A (Claims and drawings)

In Design Registration No. 728172 shown as Patent Document 3, a design of a roller cover is shown, and a product using this roller cover is available from Meiken Chemical Industry Co., Ltd. under the trade name “Bossel Coat”. In this product, after applying the coating material to the wall surface, etc., while the coating material is in an undried state, the roller cover surface is rolled so that all irregularities are transferred to the coating material. It is characterized by pattern formation by the interaction between the unevenness and the viscosity of the coating material.
Design Registration No. 728172

  In the case where all the irregularities on the roller surface are made to conform to the coating material, although it shows traces of irregularities on the roller surface, it is difficult to transfer the irregular shape as it is due to the viscosity of the coating material. Even if it was possible to do so, there was a problem that the mold release property could not be secured gradually during the pattern production, and the continuity of the pattern could not be secured.

  Even if there is something that transfers only a part of the roller surface, from the viewpoint of releasability between the roller and the coating material, the transfer pattern cannot be practically implemented unless a simple shape is selected. was there. In the invention disclosed in Patent Document 2, the pattern formed on the surface of the coating material applied by spraying, roller coating, or wrinkle is parallel to the roller rolling direction or parallel to the rolling direction. It was a line.

  The present invention provides a novel roller and a pattern forming method using the roller. In the roller, only a part of the roller surface is transferred, and depending on the selection of the use conditions, all the high portions of the protrusions of the convex pattern formed on the roller surface are transferred and protruded when forming the transfer pattern. By performing partial transfer at the next highest part of the pattern, the two parts of the transfer pattern and partial transfer pattern at the same time are required for the pattern before the roller press, which is the ground pattern. To be formed.

The invention according to claim 1 includes a cylindrical base surface as a pattern formation surrounding reference surface, and a plurality of washer-like ridges parallel to the circumferential direction to the base surface and a groove portion sandwiched between the ridges. An arc-shaped projection that partially covers is formed, and the gist of the invention is that the height of the washer-shaped protrusion is higher than the height of the arc-shaped projection .

The gist of the invention described in claim 2 is that, in the invention described in claim 1, the height of the protrusion at one end or both ends in the circumferential direction of the arc-shaped protrusion is set higher than that of the other portions.

The gist of the invention described in claim 3 is that, in the invention described in claim 1 or claim 2 , the circumferential angle covered by the arc-shaped protrusion is 60 degrees to 240 degrees.

The invention according to claim 4 is an invention using a roller, and the height difference between the protrusions and the protrusions in the patterning roller according to any one of claims 1 to 3 with respect to the surface to be coated. The gist is to apply the coating having the above coating thickness, press the surface using the patterning roller, and form a pressing pattern by the roller and a portion where no pressing occurs.

According to the first aspect of the present invention, it is possible to form a rectangular pressing pattern that exists discontinuously in the groove portion sandwiched between the parallel lines and the parallel lines with respect to the surface to be coated. In addition, the parallel lines in the pressing pattern are essential, and the rectangular pressing pattern can be made partial depending on the thickness of the coating material or the pressing strength.

According to the invention described in claim 2 , in addition to the effect of the invention described in claim 1, one end or both ends in the circumferential direction of the rectangular pressing portion can be expressed more clearly than others.

According to the fourth aspect of the present invention, the roller according to any one of the first to third aspects is used to form a parallel line on the surface to be coated and a portion sandwiched between the parallel lines. A rectangular pressing pattern can be formed. In addition, when the adjacent arc-shaped protrusions are formed at different angular positions in the circumferential direction of the roller with respect to the plurality of washer-like ridges provided on the roller, the rectangular pressing pattern is adjacent and the same A pattern that does not become a position can be formed. And when the height of the roller washer-like ridges is higher than the height of the arc-shaped protrusions, the pressing pattern of the parallel lines is clearly expressed and the rectangular pressing pattern is clearly or partially unclearly expressed. be able to. Furthermore, when the arc-shaped protrusions formed on the roller have protrusion heights at one or both ends in the circumferential direction that are higher than those of other parts, a part of the rectangular pressing pattern is unclearly expressed. , It has the effect of separating and clarifying the part where the pressing pattern exists and the part where the pressing pattern does not exist.

Hereinafter, embodiments embodying the present invention will be described.
In this invention, in addition to the parallel line pressing pattern achieved by the invention of Japanese Patent Application Laid-Open No. 2002-317551 and the design creation of the unpressed portion shown as the prior patent application 2, there is a problem between the parallel lines. The present invention provides a roller and a pattern forming method capable of forming a continuous, rectangular shape, a pattern in which a rectangular portion is completely pressed, or a pattern incomplete or completely pressed in a rectangular portion.

  The roller according to the present invention is based on the fact that a cylindrical base surface as a pattern formation surrounding reference surface and irregularities for patterning are formed on this base surface. The surrounding reference surface is not the pattern formation surface for the pattern to be formed, but exists as a reference surface for the washer-like ridges or arc-shaped protrusions that transfer the pattern. This is the reference plane located in a surrounding shape.

  In the present invention, the washer-like ridges or arcuate protrusions are comparative expressions indicating that two types of protrusions or protrusions are provided on a cylindrical base surface on which neither of them is present. Therefore, it does not mean that a part called a washer-like protrusion is produced and assembled.

  The washer-like ridges of the roller have ridges in the shape of a washer, are formed with a thickness of 2 to 10 mm and a height of 3 to 30 mm, and the plurality of ridges have an interval of 5 to 100 mm, preferably 10 to 50 mm. , Formed in parallel. In the roller of the present invention, it is assumed that the roller is parallel, and in the embodiment, it is a straight line perpendicular to the roller axis, but it does not form a straight line with respect to the roller rolling, and is inclined with respect to the roller axis. It is also possible to form protrusions that are not parallel to each other.

  The arc-shaped protrusion is formed between adjacent washer-like ridges, and is formed to be the same as the height of the washer-like ridges or 10 mm lower than that. In the case of the same height as the washer-like ridges, the rectangular pressing pattern expressed by the parallel lines and arcuate protrusions expressed by the washer-like ridges becomes a pressing pattern with the same strength against the coating material, It becomes scarce to change as a pattern.

  Therefore, by making the height of the arc-shaped protrusions 0.5 to 5 mm lower than the height of the washer-like ridges, a pattern in which the coating material is partially suppressed with the parallel lines expressed by the washer-like ridges. It can be formed. When the coating thickness of the coating material is increased, the height difference between the two can be increased to 10 mm. When the height difference is set to 0.5 to 5 mm, preferably 1 to 3 mm, a design pattern having a change can be efficiently formed without increasing the coating thickness of the coating material.

  Further, by increasing the height of the protrusions at one end or both ends in the circumferential direction of the arc-shaped protrusion as compared with other portions, one end or both ends of the rectangular pressing pattern can be clearly expressed.

  In addition, when producing a roller having three or more washer-like ridges, two or more arc-shaped protrusions are often formed, but when changes are sought in the design formed using the roller The adjacent arc-shaped projections formed in different grooves are preferably formed at different angular positions in the circumferential direction of the cylindrical base surface.

  When a plurality of arc-shaped protrusions are provided in one groove, they are naturally formed at different angular positions in the circumferential direction of the cylindrical base surface.

If the outer peripheral diameter of the roller is 20-30 cm, the circumferential angle covered by the arc-shaped projections can be made small. However, in the case of a roller cover that is held in hand, the arc-shaped projections are It is desirable that the circumferential angle of the cover is 60 degrees to 240 degrees. When this angle is less than 60 degrees or greater than 240 degrees, the balance between the portion formed by the arc-shaped protrusion and the portion where the arc-shaped protrusion does not exist and does not form the pressing pattern is deteriorated. The presser pattern is present only sparsely, and if it exceeds 240 degrees, the part where the presser pattern does not exist gives an impression that it is too large.

  When the shape of the roller is viewed as a roughly cylindrical body, when used as a manual instrument, the size of the cylinder that becomes the pattern formation width is 5 to 40 cm, preferably 20 to 30 cm, and the outside of the cylinder. The diameter is 2 to 10 cm, preferably 4 to 8 cm. When it is in this size, it is easy to use in terms of the size or weight of the roller. However, in a portion where the corner or the pattern formation width is limited, a smaller one is also used.

  In producing the roller, either a substantially cylindrical shape that can be directly attached to the support shaft of the roller, or a shape in which the roller is formed into a thin pipe shape and a cylindrical roller cover is attached, may be used. And when making the whole hollow or producing with a foam, the whole roller can be made lightweight. However, the part that contacts the support shaft or the part that the cylindrical roller cover contacts the support part must be able to maintain the shape, and the part that contacts the shaft when the roller rolls must have wear resistance. is there.

  As the material of the roller, plastic, rubber, foams thereof, or wood can be used. Rollers can be made into a predetermined shape by grinding a cylindrical material, or after making a roller model, a lightweight roller cover can be produced by foam molding of plastic or rubber, or blow molding depending on the choice of material. Can do. Further, it is possible to perform grinding or injection molding up to the formation of the washer-like ridges, and separately produce the arc-shaped protrusion portions sandwiched between the ridges, and integrate them by bonding or the like. In that case, it can also produce combining the raw material of a roller.

The manufactured roller can be used by the following procedure.
First, a pattern-forming coating material is sprayed onto the outer wall, inner wall, ceiling, floor surface, etc. of the building that is the surface to be painted, or the surface of the building material or civil engineering structure that constitutes these surfaces, and roller coating, iron coating, etc. Apply by painting. Next, the roller of this invention is immersed in a release agent that is a liquid that improves the releasability, such as water and paint thinner, and the surface is rolled in a state where the coating material is uncured, and the pressing pattern by the roller is The part which produces and the part which does not hold down are formed. When a release agent is not used, it is possible to form a presser pattern with a small area, but it is impossible to hold a collective area, and the roller is usually immersed several times in a bucket containing the release agent. The holding work is performed.

Hereinafter, examples and comparative examples embodying the embodiment will be described.
(Example 1)
The roller was manufactured by the following procedure. First, a cylindrical body made of a vinyl chloride resin having an outer diameter of 52 mm and a length of 227.5 mm is prepared. Only the washer-like ridges at both ends have a thickness of 5 mm, and the others are 4.5 mm thick. A cylindrical body having 12 grooves at a depth of 8 mm with an interval of 14 mm and 13 washer-like ridges was produced. Next, a hole for mounting the support shaft of the roller was drilled with a diameter of 7 mm on the central axis of the cylinder. However, a hole having a diameter of 16 mm and a depth of 6 mm was provided on the central axis of the cylinder only at both end portions, so that it could be screwed. In FIG. 1, the external appearance of the roller by Example 1 is shown with the perspective view. In the figure, reference numeral 1 denotes a washer-like protrusion, and reference numeral 2 denotes an arc-shaped protrusion. In FIG. 1 showing the first embodiment, the arc-shaped projections are expressed as alternately appearing on the right side and the left side of the drawing.

  The arc-shaped projections are made of polyethylene foam, and are 6 mm thick from the bottom of the groove portion as the pattern forming outer reference surface with respect to the groove portion having a depth of 8 mm formed between the washer-like protrusions. What covered 180 degree | times which is a half circumference in the circumferential direction was produced. The arc-shaped protrusions were fixed to the cylindrical body having the washer-shaped protrusions with an adhesive so that the covering positions with respect to the grooves were alternate.

(Example 2)
Until the manufacture of the cylindrical body with the washer-like ridges, it was the same as in Example 1, and the shape of the arc-shaped protrusion and the fixing position were changed. The shape of the arc-shaped protrusion is approximately 6 mm thick, but has a thickness reduction curve that is tangent to the 6 mm thick portion so that the both ends are 8 mm. The covering angle of the arcuate protrusion is 180 degrees, but the fixing position is shifted by 120 degrees between the two arcuate protrusions adjacent to each other. Protrusions appeared. Note that the same material as in Example 1 was used, and the arc-shaped protrusions were also fixed with an adhesive.

(Example 3)
The roller was manufactured by the following procedure. First, a cylindrical body made of a vinyl chloride resin having an outer diameter of 52 mm and a length of 225.5 mm is prepared. Only the washer-like ridges at both ends have a thickness of 5 mm, and the others have a thickness of 4.5 mm. A cylindrical body having 10 grooves having a depth of 8 mm and having an interval of 14 mm and 21 mm alternately and having 11 washer-like ridges was produced. Next, a hole for mounting the support shaft of the roller was drilled with a diameter of 7 mm on the central axis of the cylinder. However, a hole having a diameter of 16 mm and a depth of 6 mm was provided on the central axis of the cylinder only at both end portions, so that it could be screwed.

  The arc-shaped protrusions are made of a foamed vinyl acetate resin, and are 14 mm at a thickness of 6 mm from the bottom of the groove portion as the pattern formation outer reference surface with respect to the groove portion having a depth of 8 mm formed between the washer-like convex stripes. The width portion was prepared to cover 180 degrees, which is a half circumference, and the 21 mm width portion was prepared to cover 120 degrees, which was 1/3 circumference. These two types of arc-shaped projections are fixed to a cylindrical body having a washer-like ridge, and the covering position with respect to the groove is first fixed to the 14 mm width portion, and then the 21 mm width one to be fixed is 120. The position fixed to the 14 mm width portion to be fixed next was fixed with an adhesive while shifting by 120 degrees at the base point so that the position fixed to the 14 mm width portion to be fixed next was shifted 120 degrees.

Example 4
Until the manufacture of the cylindrical body with the washer-like ridges, it was the same as in Example 1, and the shape of the arc-shaped protrusion and the fixing position were changed. The shape of the arc-shaped protrusion is approximately 6 mm thick, but has a thickness reduction curve that is tangent to the 6 mm thick portion so that the both ends are 8 mm. The covering angle of the arc-shaped protrusions was prepared with 180 degrees and 120 degrees. The fixing positions of the two types of arc-shaped protrusions are the positions in the development view as shown in FIG. Note that the same material as in Example 1 was used, and the arc-shaped protrusions were also fixed with an adhesive.

  FIG. 2 shows a developed view slightly outside the pattern forming outer reference surface so that the formation positions of the washer-like ridges and the arc-shaped protrusions on the roller can be seen as a cross section. It is the formation part 1a of a convex ridge, and the oblique line part that descends from the right to the left indicates the formation part 2a of the arcuate protrusion. Further, in FIG. 3, in order to show that the height of the protrusion at one end or both ends in the circumferential direction of the arc-shaped protrusion is set higher than that of the other portion, the roller development in FIG. Sectional drawing when it cut | disconnects at right angles to the axis | shaft of a roller in the part which provided the circular-arc-shaped protrusion in the half circumference of the surface is shown.

  In the comparative example, the arc-shaped protrusion in Example 1 is not provided.

  When using the patterning roller described above, insert the roller into the support shaft of a separately prepared roller handle, fix it rotatably by fastening with a nut, and apply the pattern forming coating material described below, Patterning was performed so as to hold the surface. The support shaft of the roller handle is provided with a protrusion that stops the roller and a male screw that can be fastened with a nut on the insertion side.

  Pre-coat paint is applied to the flexible board, which is the substrate for coating, and 10 kg of cold water sand is added to 20 kg of the product name Granada, Kikusui Chemical Industry Co., Ltd., which is the pattern forming coating material. Viscosity that can be applied with a kind of air spray gun), and about 3 kg and 5 kg per square meter were sprayed onto the substrate for coating. Next, while the coating material was uncured, the roller of Examples 1 to 4 and Comparative Example was used with a handle mounted thereon, and the surface of the coating material was rolled while appropriately immersing the paint thinner. The surface uneven pattern was transferred.

  The pattern of the coated plate on which the transfer pattern is formed shows a difference between 3 kg / sq.m. And 5 kg / sq.m. Of the coating material. Although it was transferred, the transfer of the arc-shaped projection part was to press only the part where the coating material was sprayed thickly. Moreover, when the application amount was large, a parallel pressing line with washer-like ridges and a rectangular pressing pattern with arc-shaped protrusions were formed.

  With respect to the difference in the pressing pattern between the example and the comparative example, only the parallel line appears in the comparative example, but in Example 1, the parallel line and the rectangular pressing part appear alternately with respect to the parallel line. In Example 2, the parallel pressing line and the rectangular pressing part were shifted by 1/3 each from the adjacent rectangular shape, and the pressing pattern of the rectangular pressing part was arranged obliquely with respect to the parallel line. In the third embodiment, the rectangular pressing portions are parallel to the two types of parallel lines and the parallel spacing, the rectangular shape formed in the wide groove portion is shifted by half, and on the other hand, the rectangular shape is alternately arranged. The holding part of the pattern became a holding pattern arranged diagonally with respect to the parallel lines. In Example 4, the rectangular pressing portions having different lengths with respect to the parallel lines were apparently randomly arranged, and the rectangular pressing pattern did not feel the directionality.

Next, the technical idea that can be grasped from the embodiment will be described below.
The patterning roller according to any one of claims 1 to 5, wherein the arrangement of the arc-shaped protrusions does not have a certain directionality. The finished surface obtained by forming a pattern using a roller having this configuration makes it difficult to distinguish between the roller coatings. When the finished surface is viewed from a direction other than the front, a regular oblique pattern is generated. There is an effect that pattern spots are less likely to occur.

  The pattern forming coating material according to claim 6, wherein the coating thickness of the pattern forming coating material is larger than the difference in height between the washer-like ridges and the arc-shaped projections and smaller than the depth of the groove of the roller. Method. By adopting this forming method, the concavo-convex pattern expressed by the washer-like ridges of the roller and the convex shape of the arc-shaped protrusions are all transferred to the surface of the pattern-forming coating material. However, in the portion where the protrusion or protrusion does not press the coating material, the surface pattern when the pattern forming coating material is applied is maintained except for the protruding portion of the coating material by pressing.

  The pattern forming method according to claim 6, wherein the coating thickness of the pattern forming coating material is substantially the same as the difference in height between the washer-like ridges and the arc-shaped protrusions. As a precondition, it is necessary that the coating material for pattern formation is not flat. By adopting this forming method, a concavo-convex pattern partially pressed by the parallel lines and the arc-shaped protrusions expressed by the washer-like ridges of the roller is formed. However, in the portion where the protrusion or protrusion does not press the coating material, the surface pattern when the pattern forming coating material is applied is maintained except for the protruding portion of the coating material by pressing. There are three types of patterns on the surface to be coated: one with a sufficiently pressed ridge, one with only the top of the coating material, and one without a press surrounded by ridges and protrusions. Will be obtained.

The above-described embodiment can be modified as follows.
-In the case of providing a plurality of arc-shaped protrusions formed in the groove portion sandwiched between the washer-shaped ridges and the ridges, they can be formed with different heights.
When pattern formation is performed using a roller having multiple heights of such arc-shaped projections, a plurality of portions with different area ratios that hold down the surface of the pattern-forming coating material are created, and the resulting pattern However, it has the effect of becoming more varied.

FIG. 3 is an external perspective view of the roller of Example 1. FIG. 10 is a development view slightly outside the pattern forming outer reference surface showing the washer-like convex stripe portion and the arc-shaped protrusion portion in the fourth embodiment. Sectional drawing which shows having raised the protrusion height in the circumferential direction edge part of the arc-shaped protrusion in an Example compared with the other part.
