Description

本発明は、床材などに用いられる板材の表面に設けられている溝を塗装する装置に関する。   The present invention relates to an apparatus for coating a groove provided on the surface of a plate material used for a flooring or the like.

従来より、床材や壁材などとして、合板表面に化粧材を積層した板材が用いられており、また、その板材に木板を並べたような外観を付与するため、表面に溝加工を施した溝付板材も用いられている。この溝付板材では、通常、溝加工後にその溝に塗装を行っている。溝の塗装方法としては、溝付板材を連続的に走行させ、溝付板材上面の溝に対向して配置したディスペンサノズルから溝内に過剰な塗布液を供給し、その後、余剰塗布液を吸引ノズルユニットによって吸引除去する方法（例えば、特開平３−１３７９６８号公報参照）が知られている。   Conventionally, as a flooring material or a wall material, a plate material in which a decorative material is laminated on the surface of a plywood is used, and in order to give the appearance that a wooden board is arranged on the plate material, a groove processing is applied to the surface. Grooved plate material is also used. In this grooved plate material, the groove is usually coated after the groove processing. The groove coating method is to continuously run the grooved plate material, supply excess coating liquid into the groove from the dispenser nozzle arranged facing the groove on the upper surface of the grooved plate material, and then suck the excess coating solution A method of suctioning and removing with a nozzle unit (for example, see Japanese Patent Laid-Open No. 3-137968) is known.

しかしながら、板材表面に形成している溝は通常、１．５〜３ｍｍ程度ときわめて小さいため、ディスペンサノズルから塗布液を吐出して溝内に供給する際、走行中の溝付板材の溝がディスペンサノズルの吐出口に対してわずかに横方向にずれただけで塗布液が溝の外側にはみ出してしまい、見栄えを悪くすることがあった。これを防ぐには、溝付板材の溝をディスペンサノズルの吐出口に対して正確に位置決めして走行させる必要があるが、溝付板材に対する溝の形成位置自体に或る程度の誤差が生じているため、溝位置をディスペンサノズルの吐出口に対して正確に位置決めして走行させることはきわめて困難であった。また、ディスペンサノズルからの塗布液供給中において、吐出された塗布液が揺れることがあり、この揺れによっても塗布液が溝の外側にはみ出してしまい、見栄えを悪くすることがあった。   However, since the groove formed on the surface of the plate material is usually very small, about 1.5 to 3 mm, when the coating liquid is discharged from the dispenser nozzle and supplied into the groove, the groove of the running grooved plate material is the dispenser. Even if the nozzle is slightly displaced laterally with respect to the discharge port of the nozzle, the coating liquid protrudes outside the groove, which may deteriorate the appearance. In order to prevent this, it is necessary to accurately position and run the groove of the grooved plate material with respect to the discharge port of the dispenser nozzle, but a certain amount of error occurs in the groove formation position itself with respect to the grooved plate material. For this reason, it is extremely difficult to accurately run the groove position with respect to the discharge port of the dispenser nozzle. Further, while the coating liquid is being supplied from the dispenser nozzle, the discharged coating liquid may sway, and this swaying may cause the coating liquid to protrude to the outside of the groove, resulting in poor appearance.

特開平３−１３７９６８号公報Japanese Patent Laid-Open No. 3-137968

本発明はかかる問題点に鑑みてなされたもので、ディスペンサノズルから吐出する塗布液を、溝付板材の溝の外側にはみ出させることなく溝内に良好に供給して溝内面を塗装することの可能な、構造の簡単な溝付板材の溝塗装装置を提供することを課題とする。   The present invention has been made in view of such problems, and the coating liquid discharged from the dispenser nozzle can be satisfactorily supplied into the groove without being projected outside the groove of the grooved plate material to coat the groove inner surface. It is an object of the present invention to provide a groove coating apparatus for a grooved plate material having a simple structure.

本発明は、溝付板材の溝に対してディスペンサノズルから塗布液を吐出して供給する際における上記問題点を解決するため、そのディスペンサノズルに、該ディスペンサノズルの先端を経て前記溝内に挿入されるように取り付けられ、前記ディスペンサノズルから吐出された塗布液を前記溝内に案内する補助ガイドを設けるという構成としたものである。   In order to solve the above-described problems when the coating liquid is discharged from the dispenser nozzle and supplied to the groove of the grooved plate material, the present invention is inserted into the dispenser nozzle through the tip of the dispenser nozzle. The auxiliary guide is provided so as to guide the coating liquid discharged from the dispenser nozzle into the groove.

ここで、前記補助ガイドとしては、線材或いは樋状材を用いることが好ましい。   Here, as the auxiliary guide, it is preferable to use a wire or a hook-shaped material.

本発明によれば、ディスペンサノズルを溝付板材の溝に対して相対的に移動させながらディスペンサノズルから塗布液を吐出して溝内に供給するに当たって、吐出された塗布液が、溝内に挿入されている補助ガイドを伝って溝内に流入するため、塗布液の流れが常に安定しており、且つディスペンサノズルに対して溝付板材の溝が横方向に多少ずれても、塗布液は補助ガイドを伝って安定して溝内に供給されることとなり、塗布液を溝の外にはみ出させることなく良好に溝内に供給して、溝内面を見栄えよく塗装できる。   According to the present invention, when the dispenser nozzle is moved relative to the groove of the grooved plate material and the application liquid is discharged from the dispenser nozzle and supplied into the groove, the discharged application liquid is inserted into the groove. Since it flows into the groove along the auxiliary guide, the flow of the coating liquid is always stable, and even if the groove of the grooved plate material slightly deviates laterally with respect to the dispenser nozzle, the coating liquid is assisted. It will be stably supplied into the groove along the guide, and the coating liquid can be supplied well into the groove without protruding from the groove, so that the inner surface of the groove can be painted finely.

以下、図面に示す本発明の好適な実施の形態を説明する。図１は本発明の溝塗装装置で塗装の対象とする溝付板材の１例を示す概略斜視図、図２はその溝付板材の溝形成領域を拡大して示す概略断面図である。全体を参照符号１で示す溝付板材は、合板２の表面に化粧材３を積層した構造を有しており、その表面に、溝付板材１の長手方向に溝４を形成している。溝４の断面形状は、Ｖ字状、Ｕ字状等任意であり、この実施の形態ではＶ字状のものを示している。また、溝４のエッジは、図示したもののように角のままとしたものに限らず、丸みを付けたものとしてもよい。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention shown in the drawings will be described. FIG. 1 is a schematic perspective view showing an example of a grooved plate material to be coated by the groove coating apparatus of the present invention, and FIG. 2 is a schematic sectional view showing an enlarged groove forming region of the grooved plate material. The grooved plate material denoted as a whole by reference numeral 1 has a structure in which a decorative material 3 is laminated on the surface of a plywood 2, and grooves 4 are formed on the surface in the longitudinal direction of the grooved plate material 1. The cross-sectional shape of the groove 4 is arbitrary, such as a V shape or a U shape, and in this embodiment, a V shape is shown. Further, the edge of the groove 4 is not limited to a corner as illustrated, but may be rounded.

図３は本発明の好適な実施の形態に係る溝塗装装置の１例を示す概略側面図、図４はその一部を拡大して示す概略側面図であり、溝付板材１は断面で示している。図５（ａ）、（ｂ）、（ｃ）、（ｄ）は溝塗装装置によって溝の内面に塗装を施す状態を示す概略断面図である。全体を参照符号６で示す溝塗装装置は、溝付板材１を長手方向に、すなわち溝４に平行方向に搬送する搬送手段７と、搬送中の溝付板材１の表面の溝４に対向する位置に配置され、塗布液１３を連続的に吐出して走行中の溝付板材１の溝４内に供給するディスペンサノズル８と、該ディスペンサノズル８に塗布液を供給する供給タンク及びポンプ等を備えた塗布液供給装置（図示せず）と、ディスペンサノズル８に、該ディスペンサノズルの先端を経て前記溝内に挿入されるように取り付けられ、ディスペンサノズル８から吐出された塗布液１３を溝４内に案内する補助ガイド９と、溝付板材１の走行方向に関してディスペンサノズル８の下流に溝４に対向して配置され、溝４内に供給された塗布液１３を溝内面に押し拡げるスキージ１０等を備えている。ディスペンサノズル８に取り付けている補助ガイド９は、先端を溝４内に挿入可能で且つディスペンサノズル８から吐出された塗布液１３を溝４内に案内することができるものであれば、その構成は任意であり、この実施の形態ではピアノ線等の弾性変形可能な線材が用いられている。   FIG. 3 is a schematic side view showing an example of a groove coating apparatus according to a preferred embodiment of the present invention, FIG. 4 is a schematic side view showing a part thereof enlarged, and the grooved plate material 1 is shown in cross section. ing. 5A, 5B, 5C, and 5D are schematic cross-sectional views showing a state in which the inner surface of the groove is applied by the groove coating apparatus. The groove coating apparatus generally indicated by reference numeral 6 opposes the conveying means 7 for conveying the grooved plate material 1 in the longitudinal direction, that is, in the direction parallel to the grooves 4, and the groove 4 on the surface of the grooved plate material 1 being conveyed. A dispenser nozzle 8 which is disposed at a position and continuously discharges the coating liquid 13 and supplies it into the groove 4 of the traveling grooved plate 1, and a supply tank and a pump for supplying the coating liquid to the dispenser nozzle 8. A coating liquid supply device (not shown) provided, and the dispenser nozzle 8 are attached so as to be inserted into the groove through the tip of the dispenser nozzle, and the coating liquid 13 discharged from the dispenser nozzle 8 is grooved 4. An auxiliary guide 9 that guides inward, and a squeegee 10 that is disposed downstream of the dispenser nozzle 8 in opposition to the groove 4 with respect to the traveling direction of the grooved plate member 1 and that spreads the coating liquid 13 supplied into the groove 4 to the inner surface of the groove. etc It is provided. The auxiliary guide 9 attached to the dispenser nozzle 8 can be configured so long as the tip can be inserted into the groove 4 and the coating liquid 13 discharged from the dispenser nozzle 8 can be guided into the groove 4. In this embodiment, an elastically deformable wire such as a piano wire is used.

次に、上記構成の溝塗装装置６による塗装動作を説明する。溝付板材１が搬送手段７によって、連続的に搬送されてくると、走行中の溝付板材１の溝４内に補助ガイド９の先端が入り、その状態で溝付板材１が走行を続け、その間に、図４、図５（ａ）に示すように、ディスペンサノズル８が塗布液１３を連続的に吐出し、その塗布液１３が案内ガイド９で案内されて溝４内に供給される。この塗布液供給の間において、定位置に取り付けられているディスペンサノズル８に対して溝付板材１の溝４の位置が横方向にずれることがあるが、補助ガイド９は溝４内に挿入された状態で溝４内を滑って行き、このため、塗布液１３は溝４の外側にはみ出すことなく、溝４内に良好に供給される。かくして、溝付板材１の溝４をディスペンサノズル８に対して高精度に位置決めして走行させなくても、溝４内に塗布液を供給できる。ここで、この実施の形態に示すように補助ガイド９を弾性変形可能な材料で構成しておくと、ディスペンサノズル８と溝４の位置のずれが或る程度大きくなっても、補助ガイド９自身が変形して無理なく溝４内を滑って行くことができ、塗布液を安定して溝４内に供給できるという利点が得られる。   Next, the painting operation by the groove coating apparatus 6 having the above configuration will be described. When the grooved plate 1 is continuously conveyed by the conveying means 7, the tip of the auxiliary guide 9 enters the groove 4 of the traveling grooved plate 1, and the grooved plate 1 continues to travel in this state. In the meantime, as shown in FIGS. 4 and 5A, the dispenser nozzle 8 continuously discharges the coating liquid 13, and the coating liquid 13 is guided by the guide guide 9 and supplied into the groove 4. . During the application liquid supply, the position of the groove 4 of the grooved plate 1 may be shifted laterally with respect to the dispenser nozzle 8 attached at a fixed position, but the auxiliary guide 9 is inserted into the groove 4. Therefore, the coating liquid 13 is supplied well into the groove 4 without protruding outside the groove 4. Thus, the coating liquid can be supplied into the groove 4 without positioning the groove 4 of the grooved plate 1 with respect to the dispenser nozzle 8 with high accuracy. Here, if the auxiliary guide 9 is made of an elastically deformable material as shown in this embodiment, the auxiliary guide 9 itself even if the displacement between the position of the dispenser nozzle 8 and the groove 4 increases to some extent. It is possible to easily slide in the groove 4 due to deformation and to supply the coating liquid into the groove 4 stably.

ディスペンサノズル８が溝４内に塗布液１３を供給した後、図４、図５（ｂ）に示すように、その塗布液１３をスキージ１０が溝内面全域に押し拡げる。これにより、図４、図５（ｃ）に示すように溝４のエッジに到るまで、溝内面全域に塗布液１３が塗布されることとなる。その後、溝４の内面に押し拡げられた塗布液１３が乾燥される。これにより、図５（ｄ）に示すように、溝４の内面全域に塗膜１５が形成される。以上により、溝４の内面が全長に渡って見栄えよく塗装される。   After the dispenser nozzle 8 supplies the coating liquid 13 into the groove 4, as shown in FIGS. 4 and 5B, the squeegee 10 pushes the coating liquid 13 over the entire groove inner surface. As a result, the coating liquid 13 is applied to the entire inner surface of the groove until reaching the edge of the groove 4 as shown in FIGS. Thereafter, the coating solution 13 spread on the inner surface of the groove 4 is dried. Thereby, as shown in FIG. 5D, the coating film 15 is formed over the entire inner surface of the groove 4. In this way, the inner surface of the groove 4 is painted with good appearance over the entire length.

なお、上記した実施の形態では、補助ガイド９として線材を用いているが、補助ガイドは線材に限らず、図６、図７に示すように、Ｖ字状或いはＵ字状などの樋状材で構成された補助ガイド９Ａを用いてもよい。この場合においても、補助ガイド９Ａを弾性変形可能としておくことが、補助ガイド９Ａが溝４の位置の変化に追従して変形し、無理なく溝４内を滑って塗布液を溝４内に安定して供給できるので好ましい。   In the above-described embodiment, a wire is used as the auxiliary guide 9. However, the auxiliary guide is not limited to a wire, and as shown in FIGS. 6 and 7, a hook-shaped material such as a V shape or a U shape. You may use the auxiliary guide 9A comprised by these. Even in this case, it is possible to make the auxiliary guide 9A elastically deformable. The auxiliary guide 9A deforms following the change in the position of the groove 4 and slips easily in the groove 4 to stabilize the coating liquid in the groove 4. Therefore, it is preferable.

更に、上記した実施の形態では、棒状のスキージ１０を用いて、溝４内の塗布液１３を溝内面に押し広げているが、ここで用いるスキージ１０の形状は図示のものに限らず、適宜変更可能である。また、ディスペンサノズル８から溝４内に供給する塗布液量を多くして、溝内面全域に塗布液を塗り、必要に応じ過剰な塗布液を吸引除去する構成とすることで、スキージを省略してもよい。更に、上記した実施の形態では、ディスペンサノズル８を定位置に配置し、溝付板材１を走行させることでディスペンサノズル８を溝４に対して相対的に移動させる構成としているが、本発明はこの構成に限らず、溝付板材１を定位置に保持し、ディスペンサノズル８を（スキージ１０を用いる場合には、そのスキージ１０と一緒に）溝４に沿って移動させる構成としてもよい。   Further, in the above-described embodiment, the bar-shaped squeegee 10 is used to spread the coating liquid 13 in the groove 4 on the inner surface of the groove. However, the shape of the squeegee 10 used here is not limited to that illustrated, It can be changed. Further, the squeegee is omitted by increasing the amount of the coating liquid supplied from the dispenser nozzle 8 into the groove 4, applying the coating liquid over the entire groove inner surface, and removing the excessive coating liquid as needed. May be. Furthermore, in the above-described embodiment, the dispenser nozzle 8 is disposed at a fixed position, and the dispenser nozzle 8 is moved relative to the groove 4 by running the grooved plate 1. Not limited to this configuration, the grooved plate 1 may be held at a fixed position, and the dispenser nozzle 8 may be moved along the groove 4 (along with the squeegee 10 when the squeegee 10 is used).

なお、上記の実施の形態では、塗装対象の溝付板材１として、図１に示すように、長手方向に延びる溝４のみを備えたものを示しているが、本発明はこの構成の溝付板材１に限らず、図８に示すように、横方向に延びる溝４Ａを備えた溝付板材１Ａの溝４Ａに対しても適用可能である。なお、溝４Ａの塗装に当たっては、溝付板材１Ａを停止させておき、ディスペンサノズル８及びスキージ１０を溝４Ａに沿って移動させて塗布液の供給及び押し拡げを行う構成とすることが、短い溝４Ａに対して効率良く塗装できるので、好ましい。   In the above embodiment, the grooved plate material 1 to be coated is provided with only the groove 4 extending in the longitudinal direction as shown in FIG. As shown in FIG. 8, not only the plate material 1 but also the groove 4 </ b> A of the grooved plate material 1 </ b> A provided with the groove 4 </ b> A extending in the lateral direction is applicable. In coating the groove 4A, it is short that the grooved plate material 1A is stopped and the dispenser nozzle 8 and the squeegee 10 are moved along the groove 4A to supply and spread the coating liquid. This is preferable because the groove 4A can be efficiently painted.

以上に本発明の好適な実施の形態を説明したが、本発明はこれらの実施の形態に限定されるものではなく、特許請求の範囲の記載範囲内で適宜変更可能であることは言うまでもない。   The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments, and it is needless to say that the embodiments can be appropriately changed within the scope of the claims.
