【発明の属する技術分野】
この出願の発明は、粉粒体の散布装置に関するものである。さらに詳しくは、この出願の発明は、外装材の基材表面に砂、骨材等の粉粒体を均一にもランダムにも散布することのできる粉粒体の散布装置に関するものである。
【0002】
【従来の技術】
外壁材、屋根材等の外装材には様々な表面化粧が施されており、基材表面に砂、骨材等の粉粒体を散布し、自然石調の外観とすることが行われている。そのために用いられる装置として、凹状の充填部を表面に有し、回転により充填部に充填された粉粒体を基材表面に散布する散布ロールを備えた粉粒体の散布装置が知られている(たとえば、特許文献1参照)。
【0003】
【特許文献1】
特開平11−291227号公報
【0004】
【発明が解決しようとする課題】
しかしながら、上記特許文献に記載された粉粒体の散布装置は、基材表面に粉粒体を均一に散布することを意図して開発されたものであり、粉粒体をランダムに散布することはできない。粉粒体のランダムな散布は、変化に富んだ意匠を有する外装材の実現に有効である。だが、上記特許文献に記載された粉粒体の散布装置の場合、粉粒体のランダムな散布を行うには、充填部のパターンが部位により異なる散布ロールを作製しなければならず、コスト負担が大きくなる。
【0005】
この出願の発明は、このような事情に鑑みてなされたものであり、外装材の基材表面に砂、骨材等の粉粒体を均一にもランダムにも散布することのできる粉粒体の散布装置を提供することを解決すべき課題としている。
【0006】
【課題を解決するための手段】
この出願の発明は、上記の課題を解決するものとして、凹状の充填部を表面に有し、回転により充填部に充填された粉粒体を基材表面に散布する散布ロールを備えた粉粒体の散布装置において、散布ロールは、回転軸方向に分割された円筒形状を有する複数のパーツの組合せにより形成されることを特徴とする粉粒体の散布装置(請求項1)を提供する。
【0007】
また、この出願の発明は、各パーツが表面に有する充填部のパターンが異なること(請求項2)、各パーツは組合せ自在であり、交換可能であること(請求項3)をそれぞれ一態様として提供する。
【0008】
以下、図面に沿ってこの出願の発明の粉粒体の散布装置についてさらに詳しく説明する。
【0009】
【発明の実施の形態】
図1、図2は、それぞれ、この出願の発明の粉粒体の散布装置における散布ロールの概要を示した側面図、分解斜視図である。
【0010】
たとえば図1、図2に示したように、この出願の発明の粉粒体の散布装置では、散布ロール(1)が、回転軸(2)の方向に分割された円筒形状を有する複数のパーツ(3)の組合せにより形成される。つまり、散布ロール(1)は、円筒形状を有する複数のパーツ(3)を回転軸(2)に嵌め込む等して組み合わせることにより形成される。各パーツ(3)は、図3に示したように、表面に凹状の充填部(4)が形成されている。この充填部(4)に砂、骨材等の粉粒体が溜められ、散布ロール(1)の回転により粉粒体が充填部(4)から落下し、基材表面に粉粒体が散布される。
【0011】
充填部(4)は、図3<a>に示したようなディンプル状の他、図3<b><c><d>に示したような溝状とすることができる。また、同じディンプル状でも図3<a>に示した均一パターンのもの、不均一パターンのものとすることができる。これは、溝状の充填部(4)についても同様であり、図3<b>に示した溝が一定間隔で形成されている均一パターンのもの、溝間隔が図3<b>よりも短い図3<c>に示したもの、溝間隔が一定でない不均一パターンの図3<d>に示したもの等の各種とすることができる。また、溝形状も断面V字状、U字状等の各種が可能である。このようなパーツ(3)を用い、組み合わせて散布ロール(1)が形成される。
【0012】
たとえば、充填部(4)のパターンが同一であるパーツ(3)を組み合わせ、散布ロール(1)を形成する場合には、基材表面に砂、骨材等の粉粒体を均一に散布することができる。また、充填部(4)のパターンが異なるパーツ(3)を組み合わせて散布ロール(1)を形成する場合には、基材表面に散布される粉粒体の状態は不均一となり、ランダムとなる。たとえば、図3<a><b><c><d>に示したパーツ(3)を図4に示したように組み合わせて散布ロール(1)を形成すると、同図中に示したようなグラデーション状の粉粒体の散布が可能となる。
【0013】
このように、この出願の発明の粉粒体の散布装置では、各パーツ(3)は組合せ自在とすることができ、また、交換可能とすることができる。これにより、砂、骨材等の粉粒体を散布する散布ロール(1)の作製コストを低減することが可能となる。また、外装材の意匠を多種多様とすることができ、新規意匠の作成が容易ともなる。
【0014】
もちろん、この出願の発明は、以上の実施形態によって限定されるものではない。粉粒体の種類及び粒径、散布装置及び散布ロールの具体的な構成及び構造等の細部については様々な態様が可能であることはいうまでもない。
【0015】
【発明の効果】
以上詳しく説明したとおり、この出願の発明によって、外装材の基材表面に砂、骨材等の粉粒体を均一にもランダムにも散布することが可能となる。また、それを低コストで実現することもできる。さらに、外装材の意匠が多種多様となり、新規意匠の作成が容易となる。

[Problems to be solved by the invention]
However, the apparatus for dispersing powders and granules described in the above-mentioned patent documents is developed with the intention of uniformly dispersing the powders and granules on the surface of the base material, and is capable of randomly dispersing the powders and granules. Can not. The random application of the powder is effective in realizing an exterior material having a variety of designs. However, in the case of the apparatus for dispersing powders and granules described in the above-mentioned patent documents, in order to perform the random dispersion of the powders and granules, it is necessary to produce a scatter roll in which the pattern of the filling portion differs depending on the portion, which is a cost burden. Becomes larger.
[0005]
The invention of this application has been made in view of such circumstances, and is capable of uniformly or randomly dispersing powders such as sand and aggregate on the surface of a base material of an exterior material. It is an object of the present invention to provide a spraying device.

[0007]
Further, the invention of this application is characterized in that each part has a different pattern of a filling portion on the surface (Claim 2), and that each part can be freely combined and exchanged (Claim 3). provide.
[0008]
Hereinafter, the apparatus for dispersing powdery and granular materials according to the present invention will be described in more detail with reference to the drawings.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 and FIG. 2 are a side view and an exploded perspective view, respectively, showing the outline of a spraying roll in the powdery and granular material spraying apparatus of the present invention.
[0010]
For example, as shown in FIGS. 1 and 2, in the powder and granular material spraying apparatus of the present invention, the spraying roll (1) has a plurality of cylindrical parts divided in the direction of the rotation axis (2). It is formed by the combination of (3). That is, the spraying roll (1) is formed by fitting a plurality of parts (3) having a cylindrical shape, for example, by fitting them into the rotating shaft (2). As shown in FIG. 3, each part (3) has a concave filling portion (4) formed on the surface. Granules such as sand and aggregate are stored in the filling portion (4), and the granules fall from the filling portion (4) by the rotation of the scatter roll (1), and the granules are scattered on the surface of the base material. Is done.
[0011]
The filling portion (4) may have a dimple shape as shown in FIG. 3 <a> or a groove shape as shown in FIG. 3 <b><c><d>. Further, the same dimple shape can be a uniform pattern or a non-uniform pattern shown in FIG. The same applies to the groove-shaped filling portion (4), which is a uniform pattern in which the grooves shown in FIG. 3 <b> are formed at regular intervals, and the groove interval is shorter than that in FIG. 3 <b>. Various types such as those shown in FIG. 3 <c> and those shown in FIG. 3 <d> having a non-uniform pattern in which the groove intervals are not constant can be used. Also, various groove shapes such as a V-shaped cross section and a U-shaped cross section are possible. A spraying roll (1) is formed using such parts (3) in combination.
[0012]
For example, when the parts (3) having the same pattern of the filling part (4) are combined to form the scatter roll (1), powder such as sand and aggregate is uniformly scattered on the surface of the base material. be able to. Further, in the case where the spraying roll (1) is formed by combining parts (3) having different patterns of the filling section (4), the state of the powder and granules sprayed on the surface of the base material becomes uneven and random. . For example, when the parts (3) shown in FIG. 3 <a><b><c><d> are combined as shown in FIG. 4 to form a scatter roll (1), It is possible to spray a gradation-like powder.
[0013]
As described above, in the powder and granule spraying apparatus of the invention of this application, each part (3) can be freely combined and can be replaced. This makes it possible to reduce the manufacturing cost of the spraying roll (1) for spraying powders such as sand and aggregate. In addition, the design of the exterior material can be diversified, which facilitates creation of a new design.
[0014]
Of course, the invention of this application is not limited by the above embodiments. It goes without saying that various aspects are possible for details such as the type and particle size of the powder and the specific configuration and structure of the spraying device and the spraying roll.
[0015]
【The invention's effect】
As described above in detail, according to the invention of this application, it is possible to spray powder particles such as sand and aggregate uniformly or randomly on the surface of the base material of the exterior material. In addition, it can be realized at low cost. Further, the design of the exterior material becomes diversified, and creation of a new design becomes easy.
