JP 11-291227 A

上記のように従来は基材に一種類の粉体が均一に散布された単純な装飾がなされていたものであるが、近年の建築板等に対する高意匠化の要請に伴い、粉体を散布した基材に対しても更に複雑な意匠模様の付与が求められるようになってきている。   As mentioned above, a simple decoration was applied in which a single type of powder was evenly dispersed on the base material as described above. Even more complicated design patterns are required to be applied to the base material.

本発明は上記の点に鑑みて為されたものであり、基材に粉体を散布することにより基材に高意匠性の装飾を施すことができる粉体散布装置を提供することを目的とするものである。   The present invention has been made in view of the above points, and an object of the present invention is to provide a powder spraying device capable of applying a high design decoration to a base material by spraying the powder onto the base material. To do.

本発明に係る粉体散布装置は、基材１を一方向に搬送する搬送手段２と、前記搬送手段２による基材１の搬送経路３の上方に配置され、この搬送経路３を搬送される基材１に向けて粉体４を散布する散布手段５とを具備し、前記散布手段５は、前記搬送方向と直交する方向に配列された複数のノズル６と、前記各ノズル６の開閉制御を行う開閉手段７と、前記各ノズル６から噴出された粉体４を基材１の搬送方向と直交する方向に拡散させた後に基材１に散布する粉体拡散手段８とを備えることを特徴とする。   The powder spraying apparatus according to the present invention is arranged above a transport path 2 for transporting the base material 1 in one direction and the transport path 3 of the base material 1 by the transport means 2, and is transported through the transport path 3.

この粉体散布装置は、上記散布手段５における複数の開閉手段７によるノズル６の開閉を独立して制御する制御手段９を具備することが好ましい。   This powder spraying device preferably includes a control means 9 for independently controlling the opening and closing of the nozzle 6 by the plurality of opening and closing means 7 in the spraying means 5.

また、上記散布手段５は、基材１の搬送方向に沿って複数配設することが好ましい。   Moreover, it is preferable that a plurality of the spraying means 5 are arranged along the transport direction of the base material 1.

更に、上記粉体拡散手段８は、ノズル６の下方に配された傾斜板９にて構成することが好ましい。   Furthermore, the powder diffusing means 8 is preferably constituted by an inclined plate 9 disposed below the nozzle 6.

本発明によれば、搬送経路上で基材を搬送しながらこの基材上の所定の領域が散布手段の下方を通過する際にノズルを開くと、ノズルから噴出した粉体が粉体拡散手段により拡散された状態で基材上の所定の領域に散布されることとなり、基材上に粉体をパターン状に散布すると共に粉体が散布された領域では粉体は均一に散布することができて、基材に対して粉体散布にて高意匠性の装飾を施すことができるものである。   According to the present invention, when the nozzle is opened when a predetermined area on the base material passes below the spraying means while transporting the base material on the transport path, the powder ejected from the nozzle is changed to the powder diffusion means. The powder is dispersed in a predetermined area on the base material in a diffused state, and the powder can be dispersed on the base material in a pattern and the powder can be uniformly dispersed in the area where the powder is dispersed. It is possible to decorate the base material with high design by powder dispersion.

Further, a highly designed decoration can be applied.

また、ノズルの下方に配された傾斜板にて粉体拡散手段を構成すると、ノズルから噴出された粉体は傾斜板上を滑落しながら傾斜板の幅方向に拡散されることとなり、これにより粉体の均一な散布が可能となるものである。   Further, when the powder diffusing means is constituted by the inclined plate arranged below the nozzle, the powder ejected from the nozzle is diffused in the width direction of the inclined plate while sliding down on the inclined plate. It is possible to uniformly disperse the powder.

以下、本発明を実施するための最良の形態を、図１乃至５を示して説明する。   Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

本発明に係る粉体散布装置は、基材１を搬送する搬送手段２と、搬送手段２にて搬送される基材１に向けて粉体４を散布する散布手段５とを具備する。   The powder spraying device according to the present invention includes transporting means 2 for transporting the base material 1 and spraying means 5 for spraying the powder 4 toward the base material 1 transported by the transporting means 2.

搬送手段２としては適宜のものを用いることができ、例えば図１に示すようにプーリー１１間に無端ベルト１２を掛架して構成されるタイミングベルト等のベルトコンベア１０を設けることができる。   As the conveying means 2, an appropriate one can be used. For example, as shown in FIG. 1, a belt conveyor 10 such as a timing belt configured by hanging an endless belt 12 between pulleys 11 can be provided.

上記搬送手段２による基材１の搬送経路３の上方には、散布手段５が設けられる。この散布手段５は、搬送経路３を搬送される基材１の表面に仮想的に設定された複数の領域１３にそれぞれ個別に粉体４を散布するものである。この領域１３は適宜設定されるが、例えば基材１の搬送方向及びこれと直交する方向に縦横に並んだ升目状に区画して設定することができる（図５参照）。またこの領域は例えば一辺が１０〜１００ｍｍの範囲とすることができ、具体例として縦２０ｍｍ、横２０ｍｍの寸法に設定することができる。   Dispersing means 5 is provided above the conveying path 3 of the substrate 1 by the conveying means 2. The spraying means 5 sprays the powder 4 individually to a plurality of regions 13 virtually set on the surface of the base material 1 transported along the transport path 3. The region 13 is appropriately set. For example, the region 13 can be set by dividing it into a grid shape arranged vertically and horizontally in the conveyance direction of the base material 1 and the direction orthogonal thereto (see FIG. 5). Moreover, this area | region can be made into the range whose side is 10-100 mm, for example, and can set it to the dimension of 20 mm long and 20 mm wide as a specific example.

図示の例では、散布手段５は、粉体４が貯留される貯留容器１４の下部に下方に開口するノズル６を設けて構成されている。ノズル６は基材１の搬送方向と直交する方向に亘って複数個設けられ、その個数は基材１に設定された搬送方向の領域１３の数と少なくとも同一の数とし、搬送経路３を搬送される基材１に設定される各領域１３が、いずれかのノズル６の下方を通過するようにする。   In the illustrated example, the spraying means 5 is configured by providing a nozzle 6 that opens downward at a lower portion of a storage container 14 in which the powder 4 is stored. A plurality of nozzles 6 are provided in a direction orthogonal to the transport direction of the substrate 1, and the number thereof is at least the same as the number of regions 13 in the transport direction set on the substrate 1, and transports the transport path 3. Each region 13 set in the base material 1 to be made passes below any one of the nozzles 6.

各ノズル６にはノズル６の開閉を行う開閉手段７が設けられており、例えばノズル６の開口の直下に密接して配置されることによりノズル６を閉じる位置と、前記位置から横方向に変位してノズル６を開放する位置との間で移動可能な開閉片１５と、この開閉片１５を駆動する適宜のアクチュエータ１６とを設けることができる。図示の例では開閉片１５は水平な板状体であり、その端縁から下方に向けて固定片１７が延出され、この固定片１７が油圧シリンダ等のシリンダ１８における水平方向に進退駆動するプランジャ１９の端部に固定されている。前記シリンダ１８はノズル６に対して基材１の搬送方向側に配設され、各ノズル６ごとに設けられた複数のシリンダ１８が基材１の搬送方向と直交する方向に並んで設けられている。図２乃至４中の符号２５は貯留容器１４に対してシリンダ１８を固定するために設けられた固定板である。このとき図２に示すようにプランジャ１９が突出状態にあるときに開閉片１５がノズル６を閉塞し、図３に示すようにプランジャ１９が引き込み状態にあるときに開閉片１５がノズル６を開放する。   Each nozzle 6 is provided with an opening / closing means 7 for opening and closing the nozzle 6. For example, the nozzle 6 is disposed in close contact with the opening of the nozzle 6 to close the nozzle 6, and is displaced laterally from the position. Thus, an opening / closing piece 15 movable between the position where the nozzle 6 is opened and an appropriate actuator 16 for driving the opening / closing piece 15 can be provided. In the illustrated example, the open / close piece 15 is a horizontal plate-like body, and a fixed piece 17 extends downward from an edge of the open / close piece 15. The fixed piece 17 is driven to advance and retreat in a horizontal direction in a cylinder 18 such as a hydraulic cylinder. The end of the plunger 19 is fixed. The cylinder 18 is disposed on the side of the substrate 1 in the conveyance direction with respect to the nozzle 6, and a plurality of cylinders 18 provided for each nozzle 6 are arranged in a direction orthogonal to the conveyance direction of the substrate 1. Yes. Reference numeral 25 in FIGS. 2 to 4 is a fixing plate provided to fix the cylinder 18 to the storage container 14. At this time, the opening / closing piece 15 closes the nozzle 6 when the plunger 19 is in the protruding state as shown in FIG. 2, and the opening / closing piece 15 opens the nozzle 6 when the plunger 19 is in the retracted state as shown in FIG. To do.

また、この散布手段５の各ノズル６の下方には粉体拡散手段８が設けられる。粉体拡散手段８は、ノズル６から噴出された粉体４を基材１の搬送方向と直交する方向に拡散させた後に基材１に散布するものであり、図示の例ではノズル６の下方に傾斜板９を配設して構成されている。傾斜板９は基材１の搬送方向に対して傾斜（図示の例では基材１の搬送方向側が下り傾斜）しており、上側の傾斜面の上方にノズル６が配置されている。傾斜板９の両側端縁からは、上面の傾斜面側に突出する堰片２０がそれぞれ延出されている。各ノズル６の下方に設けられた複数の傾斜板９は、基材１の搬送方向と直交する方向に互いに密接して並ぶように配設されている。
この傾斜板９の幅寸法は、傾斜板９から散布される粉体４の拡散幅に一致させるものであり、すなわち基材１に設定される領域１３の搬送方向と直交する方向の幅寸法と合致させる。この幅寸法は前記領域１３の幅寸法に応じて適宜設定されるが、１０〜１００ｍｍの範囲とすることができる。また、搬送経路３を搬送される基材１上に設定されている各領域１３が、いずれかの傾斜板９の下方を通過するように傾斜板９の配置位置が設定される。 Further, powder diffusing means 8 is provided below each nozzle 6 of the spraying means 5. The powder diffusing means 8 diffuses the powder 4 ejected from the nozzle 6 in the direction orthogonal to the conveying direction of the base material 1 and then spreads it on the base material 1. An inclined plate 9 is disposed on the top. The inclined plate 9 is inclined with respect to the conveyance direction of the substrate 1 (in the example shown, the conveyance direction side of the substrate 1 is inclined downward), and the nozzle 6 is disposed above the upper inclined surface. From both side edges of the inclined plate 9, weir pieces 20 projecting toward the inclined surface side of the upper surface are respectively extended. The plurality of inclined plates 9 provided below each nozzle 6 are arranged so as to be closely aligned with each other in a direction orthogonal to the conveying direction of the base material 1.
The width dimension of the inclined plate 9 is made to coincide with the diffusion width of the powder 4 dispersed from the inclined plate 9, that is, the width dimension in the direction orthogonal to the conveying direction of the region 13 set on the substrate 1. Match. The width dimension is appropriately set according to the width dimension of the region 13, but can be in the range of 10 to 100 mm. In addition, the arrangement position of the inclined plate 9 is set so that each region 13 set on the base material 1 conveyed through the conveyance path 3 passes below any one of the inclined plates 9.

このような散布手段５が、図１，５に示すように基材１の搬送方向に沿って複数設けられている。散布手段５の個数は、基材１に散布される粉体４の種類に応じた数である。   A plurality of such spraying means 5 are provided along the conveying direction of the substrate 1 as shown in FIGS. The number of spraying means 5 is a number corresponding to the type of powder 4 sprayed on the substrate 1.

各散布手段５のノズル６の開閉は、それぞれ独立に制御され、かかる制御を行うための制御手段９として、散布制御システム２１が設けられている（図１参照）。   Opening and closing of the nozzles 6 of each spraying means 5 is independently controlled, and a spraying control system 21 is provided as a control means 9 for performing such control (see FIG. 1).

散布制御システム２１は、各種のＣＰＵ、ＲＯＭ、ＲＡＭ等から構成されるものであり、散布データ作成部２２、散布制御部２３、ノズル制御部２４等を備えて形成してある。散布データ作成部２２は、予め作成された色柄パターンのデータを入力して保存する。この色柄パターンは、上記のように基材１の表面に複数の領域１３を設定する場合に、各領域１３の基材１上の位置と、この各領域１３に散布される粉体４の種類とを対応させた情報である。散布制御部２３は、散布を行なう基材１に応じた色柄パターンのデータを散布データ作成部２２から取り出し、この色柄パターンのデータに基づいて、ノズル制御部２４に制御信号を出力するものである。またノズル制御部２４はノズル６の開閉を行う各開閉手段７に接続してあり、散布制御部２３から入力される制御信号に基づいて各開閉手段７を制御するものである。このノズル制御部２４としては、例えば開閉手段７として上記のようなシリンダ１８（油圧シリンダ）にて駆動するものを設ける場合に、このシリンダ１８の油圧制御を行う油圧ポンプ等を設けることができる。   The spray control system 21 includes various CPUs, ROMs, RAMs, and the like, and includes a spray data creation unit 22, a spray control unit 23, a nozzle control unit 24, and the like. The scatter data creation unit 22 inputs and stores data of a color pattern created in advance. As described above, when the plurality of regions 13 are set on the surface of the base material 1 as described above, the color pattern pattern indicates the position of each region 13 on the base material 1 and the powder 4 dispersed in each region 13. This information is associated with the type. The spray control unit 23 extracts color pattern data corresponding to the base material 1 to be sprayed from the spray data creation unit 22 and outputs a control signal to the nozzle control unit 24 based on the color pattern data. It is. The nozzle control unit 24 is connected to each opening / closing means 7 for opening / closing the nozzle 6, and controls each opening / closing means 7 based on a control signal input from the spraying control unit 23. As the nozzle control unit 24, for example, when an opening / closing means 7 that is driven by the cylinder 18 (hydraulic cylinder) as described above is provided, a hydraulic pump or the like that controls the hydraulic pressure of the cylinder 18 can be provided.

また、搬送経路３上に基材１を位置決めして配置する適宜の位置決め手段を設けてこの位置決め手段にて位置決めされる基材１の位置を散布制御部２３に記憶させたり、或いは搬送経路３上の基材１の配置位置と基材１の搬送速度とを測定する適宜のセンサ等を設けてその測定情報に基づき散布制御部２３にて基材１の搬送方向を演算して導出するようにしたりして、搬送経路３上を搬送される基材１の位置を散布制御部２３が認識できるようにすることが好ましい。   Further, an appropriate positioning means for positioning and arranging the base material 1 on the transport path 3 is provided, and the position of the base material 1 positioned by the positioning means is stored in the spraying control unit 23, or the transport path 3 An appropriate sensor or the like for measuring the arrangement position of the upper base material 1 and the transport speed of the base material 1 is provided, and the transport direction of the base material 1 is calculated and derived by the distribution control unit 23 based on the measurement information. For example, it is preferable that the spraying control unit 23 can recognize the position of the base material 1 transported on the transport path 3.

このようにして形成される粉体散布装置を用いて基材１の表面に粉体４を散布するにあたり、基材１としては適宜のものを用いることができるが、例えばセメント、シリカ、補強繊維等を主成分とするセメント系の水性スラリーを抄造法、注型法等で成形した後に、養生硬化させた無機質板を用いることができる。   When the powder 4 is sprayed on the surface of the base material 1 using the powder spraying device thus formed, an appropriate base material 1 can be used. For example, cement, silica, reinforcing fiber It is possible to use an inorganic plate that has been cured and cured after a cement-based aqueous slurry containing, for example, a main component is formed by a papermaking method or a casting method.

基材１には、予めベース塗装を施しておいても良い。このとき使用できるベース塗料としては、アクリルエマルション系等のものが挙げられる。このベース塗装時には、粉体４散布前に基材１上のベース塗料を予め硬化成膜したベース塗膜を形成しておいても良いし、基材１上のベース塗料を硬化成膜しない軟質な状態のままにしておいても良い。   The base material 1 may be subjected to base coating in advance. Examples of the base paint that can be used at this time include acrylic emulsions and the like. At the time of this base coating, a base coating film in which the base paint on the base material 1 is cured and formed in advance may be formed before the powder 4 is sprayed, or the base paint on the base material 1 is not softly formed into a film. You can leave it in the correct state.

また、各散布手段５の貯留容器１４には、基材１への散布に供する粉体４を貯留しておく。粉体４としては適宜のものを挙げることができるが、例えば、無機焼成顔料で着色した天然珪石等の骨材（カラーサンド）や、これを複数種混合したもの（ミックスサンド）、アクリル樹脂を高分子化したもの（アクリルビーズ）等を挙げることができ、またその粒径は特に制限されないが５０〜３００μｍの範囲のものを用いることができる。複数の散布手段５における各貯留容器１４には、それぞれ異なる種類の所定の粉体４を貯留し、各貯留容器１４に貯留されている粉体４の種類を散布制御部２３に記憶させておく。また各散布手段５における各ノズル６は初期状態では図２に示すような閉状態としておく。   In addition, the storage container 14 of each spraying means 5 stores the powder 4 to be sprayed on the base material 1. Examples of the powder 4 include suitable ones. For example, aggregates (color sand) such as natural silica stone colored with an inorganic calcined pigment, a mixture of a plurality of these (mix sand), acrylic resin, etc. Polymerized ones (acrylic beads) and the like can be mentioned, and the particle diameter is not particularly limited, but those in the range of 50 to 300 μm can be used. Each storage container 14 in the plurality of spraying means 5 stores different types of predetermined powder 4, and the type of powder 4 stored in each storage container 14 is stored in the spray control unit 23. . Each nozzle 6 in each spraying means 5 is in a closed state as shown in FIG. 2 in the initial state.

そして、上記のような基材１１をまず搬送手段２に供給し、搬送経路３上で搬送する。搬送経路３上の基材１は複数の散布手段５の下方を順次通過する。   Then, the base material 11 as described above is first supplied to the transport means 2 and transported on the transport path 3. The base material 1 on the transport path 3 sequentially passes below the plurality of spraying means 5.

この基材１の搬送過程で、散布制御システム２１は色柄パターンのデータと搬送経路３上の基材１の配置位置とに基づき、搬送経路３上の所定の領域１３が、この領域１３に散布されるべき粉体４を散布する散布手段５の下方を通過する際に、ノズル制御部２４を駆動して図３に示すように前記領域１３に対応するノズル６を開放する。ノズル６が開放されると、ノズル６からは貯留容器１４内に貯留された粉体４が噴出され、この粉体４が傾斜板９（粉体拡散手段８）に受け止められる。粉体４は図４に示すようにこの傾斜板９上を滑落しながら傾斜板９の幅方向に広げられると共にその広がり幅が堰片２０によって規制されて、傾斜板９の幅方向寸法と一致する幅、すなわち基板上の領域１３の幅寸法と一致する幅で、基板上の所定の領域１３に散布される。このとき散布制御システム２１は傾斜板９の下端の直下に領域１３の搬送方向の前端が到達した時点でこの粉体４の散布が開始され、この領域１３の後端が傾斜板９の下端の直下に到達した時点で粉体４の散布を停止するようにノズル制御部２４を制御するが、ノズル６からの粉体４の噴出開始から、このノズル６が傾斜板９を介して所定の領域１３に到達するまでの間の搬送経路３上における基材１の移動距離を考慮してノズル６の開閉を制御することが好ましい。   In the process of transporting the base material 1, the spraying control system 21 creates a predetermined area 13 on the transport path 3 in this area 13 based on the color pattern data and the arrangement position of the base material 1 on the transport path 3. When passing below the spraying means 5 for spraying the powder 4 to be sprayed, the nozzle controller 24 is driven to open the nozzle 6 corresponding to the region 13 as shown in FIG. When the nozzle 6 is opened, the powder 4 stored in the storage container 14 is ejected from the nozzle 6, and the powder 4 is received by the inclined plate 9 (powder diffusion means 8). As shown in FIG. 4, the powder 4 is spread in the width direction of the inclined plate 9 while sliding down on the inclined plate 9, and the spread width is regulated by the weir piece 20 to coincide with the width direction dimension of the inclined plate 9. Is spread over the predetermined region 13 on the substrate with the same width as the width of the region 13 on the substrate. At this time, the spraying control system 21 starts spraying the powder 4 when the front end in the transport direction of the region 13 reaches just below the lower end of the inclined plate 9, and the rear end of the region 13 is the lower end of the inclined plate 9. The nozzle control unit 24 is controlled so as to stop the spraying of the powder 4 when it reaches directly below. From the start of the spraying of the powder 4 from the nozzle 6, the nozzle 6 passes through the inclined plate 9 to a predetermined area. It is preferable to control the opening and closing of the nozzle 6 in consideration of the moving distance of the base material 1 on the transport path 3 until reaching 13.

このようにして、複数の各散布手段５にてそれぞれ粉体４を散布することにより、基材１上の所定の領域１３に所定の種類の粉体４が散布され、図５に示すように基材１表面に複数の粉体４がそれぞれ異なるパターン状に配置されて構成される所望の意匠模様が付与されることとなり、例えば文字や絵柄等を表すことも可能となる。また、このとき意匠模様は散布された粉体により形成されるため自然な風合いの模様を形成することが可能となる。   In this manner, by spraying the powder 4 by each of the plurality of spraying means 5, a predetermined type of powder 4 is sprayed on the predetermined region 13 on the substrate 1, as shown in FIG. A desired design pattern configured by arranging a plurality of powders 4 in different patterns on the surface of the base material 1 is given, and for example, it is possible to represent characters, designs, and the like. At this time, since the design pattern is formed by the dispersed powder, a natural texture pattern can be formed.

上記工程による粉体４の散布後、基材１は搬送手段２から導出される。この基材１に対しては必要に応じて適宜の後処理が施される。   After the powder 4 is dispersed by the above process, the substrate 1 is led out from the conveying means 2. The base material 1 is subjected to an appropriate post-treatment as necessary.

例えば粉体４の散布に先立って基材１にベース塗料を塗布し、且つこのベース塗料を硬化成膜していない状態で粉体４を散布した場合には、粉体４の散布後にベース塗料を加熱処理等により硬化成膜することで基材１上に粉体４を定着することができる。   For example, when the base paint is applied to the base material 1 prior to the spraying of the powder 4 and the powder 4 is sprayed in a state where the base paint is not cured, the base paint is applied after the powder 4 is sprayed. The powder 4 can be fixed on the substrate 1 by forming a cured film by heat treatment or the like.

また、粉体４の散布がなされた基材１表面にクリア塗料を塗布成膜してクリア塗膜を形成したり、エナメル塗料を塗布成膜してエナメル塗膜を形成したりしても良い。この場合、基材１上の粉体４がクリア塗膜やエナメル塗膜にて被覆されて保護されると共に基材１に定着される。   Alternatively, a clear coating may be formed on the surface of the substrate 1 on which the powder 4 has been dispersed to form a clear coating, or an enamel coating may be applied to form an enamel coating. . In this case, the powder 4 on the substrate 1 is covered and protected with a clear coating or enamel coating and is fixed to the substrate 1.

また更にシロキサン系等の無機質塗料を塗布成膜した無機質塗膜や、かかる無機質塗料に光触媒を含有させた光触媒塗料を塗布成膜した光触媒層を形成しても良い。   Further, an inorganic coating film in which an inorganic coating such as siloxane is applied and a photocatalyst layer in which a photocatalytic coating containing a photocatalyst is added to the inorganic coating may be formed.
