【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ために、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、各パーツは、表面に有する充填部のパターンが異なり、ディンプル状で均一パターンのものまたは不均一パターンのもの、溝状で長いまたは短い溝間隔が一定に形成されている均一パターンのもの、または溝間隔が一定でない不均一パターンのものであり、交換可能であることを特徴としている。
【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のものがある。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がある。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>に示したものがあ。溝形状断面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】
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、基材表面に砂、骨材等の粉粒体均一に散布され。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、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。

BACKGROUND OF THE INVENTION
The invention of this application relates to a powder particle disperser. More specifically, the invention of this application relates to a powder particle dispersion device that can uniformly and randomly distribute powder particles such as sand and aggregate on the surface of a base material of an exterior material.
[0002]
[Prior art]
Various exterior decorations are applied to exterior materials such as outer wall materials and roofing materials, and powders such as sand and aggregate are spread on the surface of the base material to make it look like a natural stone. Yes. As a device used for that purpose, there is known a spraying device for a granular material which has a concave filling portion on the surface and has a spraying roll for spraying the granular material filled in the filling portion by rotation onto the substrate surface. (For example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-11-291227 [0004]
[Problems to be solved by the invention]
However, the powder particle dispersion device described in the above-mentioned patent document was developed with the intention of uniformly distributing the powder particles on the surface of the base material, and randomly distribute the powder particles. I can't. Random dispersion of powder particles is effective for realizing an exterior material having a design that is rich in change. However, in the case of the granular material spraying device described in the above-mentioned patent document, in order to randomly spray the granular material, it is necessary to create a spraying roll in which the pattern of the filling portion differs depending on the part, and the cost burden Becomes larger.
[0005]
The invention of this application has been made in view of such circumstances, and can be used to uniformly and randomly disperse particles such as sand and aggregate on the surface of the base material of the exterior material. Providing a spraying device is a problem to be solved.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention of this application has a concave filling portion on the surface, and a powder granule provided with a spreading roll for spraying a granular material filled in the filling portion by rotation onto the substrate surface. In the body spraying device, the spraying roll is formed by a combination of a plurality of parts having a cylindrical shape divided in the direction of the rotation axis , and each part has a different pattern of filling parts on the surface, a dimple shape and a uniform pattern. those things or uneven patterns, those of homogeneous pattern long or short groove spacing in a groove shape is formed at a constant, or are of heterogeneous pattern groove spacing is not constant, characterized replaceable der Rukoto It is with.
[0008]
Hereinafter, the powder particle dispersion device of the invention of this application will be described in more detail with reference to the drawings.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 and FIG. 2 are a side view and an exploded perspective view, respectively, showing an outline of a spray roll in the powder particle spray device of the invention of this application.
[0010]
For example, as shown in FIGS. 1 and 2, in the powder particle spraying device of the invention of this application, the spray roll (1) has a plurality of parts having a cylindrical shape divided in the direction of the rotation axis (2). It is formed by the combination of (3). That is, the spreading roll (1) is formed by combining a plurality of parts (3) having a cylindrical shape by fitting them into the rotating shaft (2). As shown in FIG. 3, each part (3) has a concave filling portion (4) formed on its surface. In this filling part (4), powder particles such as sand and aggregate are accumulated, and the powder particles fall from the filling part (4) by the rotation of the spray roll (1), and the powder particles are spread on the surface of the substrate. Is done.
[0011]
Filling part (4), in addition to the dimples as shown in FIG. 3 <a>, Ru grooved Monogaa as shown in FIG. 3 <b><c><d>. Further, those of homogeneous pattern shown in FIG. 3 <a> at the same dimple-like, there Ru those uneven pattern. The same applies to the groove-shaped filling portion (4). The groove shown in FIG. 3 <b> has a uniform pattern in which the grooves are formed at a constant interval, and the groove interval is shorter than that in FIG. 3 <b>. Figure 3 shows the <c>, there Ru which groove spacing is shown in FIG. 3 <d> heterogeneous non-uniform pattern. Groove shape is a V-shaped cross section can have various types of U-shaped or the like. A sprinkling roll (1) is formed using such parts (3).
[0012]
Combining part pattern of the filling portion (4) are the same (3), to form a spraying roll (1), the substrate surface sand, granular material of the aggregate and the like Ru are uniformly scattered. When the pattern of Filling unit (4) to form a distribution roll (1) a combination of different parts (3), the state of the particulate material to be sprayed on the substrate surface becomes uneven, and random. For example, when the parts (3) shown in FIGS. 3 <a><b><c><d> are combined as shown in FIG. 4 to form the spreading roll (1), as shown in FIG. It is possible to disperse gradation-like granular materials.
[0013]
As described above, in the powder particle dispersion device of the invention of this application, each part (3) can be freely combined and can be exchanged. Thereby, it becomes possible to reduce the production cost of the dispersion | distribution roll (1) which disperse | distributes granular materials, such as sand and an aggregate. Moreover, the design of the exterior material can be varied, and a new design can be easily created.
[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, the invention of this application makes it possible to uniformly and randomly disperse powders such as sand and aggregate on the surface of the base material of the exterior material. It can also be realized at low cost. Furthermore, the design of the exterior material becomes diverse, and it becomes easy to create a new design.
