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、溝を含む板材表面全域に塗布液を塗布し、その後板材表面の塗布液をローラで掻き取ることで、溝内面のみに塗布液を残し、結果的に溝内面に塗装を行う方法(例えば、特開平7−117204号公報参照)が知られており、また、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)も知られている。   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 apply the coating solution over the entire surface of the plate material including the groove, and then scrape the coating solution on the surface of the plate material with a roller, leaving the coating solution only on the groove inner surface, and consequently coating the groove inner surface. (For example, refer to Japanese Patent Application Laid-Open No. 7-117204), and a method of supplying an excessive coating solution into the groove and then removing the excess coating solution by suction with a suction nozzle unit (for example, JP-A-3-137968) is also known.

しかしながら、溝を含む板材表面全域に塗布液を塗布し、その後板材表面の塗布液をローラで掻き取る方法では、板材表面の塗布液の掻き取りが困難であり、確実に掻き取るには、掻き取り用のローラを5〜8段というように多段に配置しなければならず、設備が大がかりとなるという問題があった。また、溝付板材の表面にエンボス加工を施したものが知られており、近年そのエンボス加工をより深くすることが行われているが、そのようなエンボス加工を施した溝付板材では、表面に塗布した塗布液の掻き取りが一層困難となるという問題があった。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では、塗布液が溝の外側にはみ出すとか、溝のエッジまで届かないといったことがあり、見栄えを悪くすることがあった。   However, in the method in which the coating liquid is applied to the entire surface of the plate material including the groove, and then the coating solution on the surface of the plate material is scraped with a roller, it is difficult to scrape the coating solution on the surface of the plate material. There was a problem that the rollers for taking up had to be arranged in multiple stages, such as 5 to 8, so that the facilities would become large. In addition, it is known that the surface of the grooved plate material has been embossed, and in recent years, the embossing has been made deeper. There has been a problem that it becomes more difficult to scrape off the coating solution applied to the substrate. In the method of supplying excess coating solution into the groove and then removing the excess coating solution by suction with the suction nozzle unit, the coating solution may protrude outside the groove or may not reach the edge of the groove. There was something wrong.

本発明はかかる問題点に鑑みてなされたもので、溝付板材の溝内面を、溝のエッジまできれいに塗装することができる構造簡単な、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 it is an object of the present invention to provide a groove coating device for a grooved plate material with a simple structure capable of beautifully coating the groove inner surface of the grooved plate material up to the edge of the groove. To do.

本発明の溝塗装装置は上記課題を解決するため、塗布液を連続的に吐出して溝付板材の溝内に供給するディスペンサノズルと、溝内に供給された塗布液を溝内面に押し拡げるスキージと、前記ディスペンサノズル及びスキージを、前記板材の溝に対して相対的に移動させる手段を備え、そのスキージが、前記溝の両側のエッジに押し当てることで塗布液の溝外への漏れ出しを防止する漏れ防止面を備えているという構成としたものである。   In order to solve the above problems, the groove coating apparatus of the present invention continuously dispenses a coating liquid and supplies it into the groove of the grooved plate material, and pushes the coating liquid supplied into the groove to the groove inner surface. A means for moving the squeegee, the dispenser nozzle and the squeegee relative to the groove of the plate material is provided, and the squeegee leaks out of the groove of the coating liquid by pressing against the edges on both sides of the groove. It is set as the structure provided with the leak prevention surface which prevents this.

ここで、前記スキージには、溝内の塗布液に接する部分に、塗布液を通すための通路とそれにつながる塗布液溜まりを設けておくことが好ましい。   Here, it is preferable that the squeegee is provided with a passage for passing the coating solution and a coating solution reservoir connected to the passage in a portion in contact with the coating solution in the groove.

本発明装置によれば、溝付板材の溝に対してディスペンサノズルで塗布液を連続的に供給してゆき、その塗布液をスキージで溝内面全域に押し拡げてゆくことで、溝内面に塗装を施すことができる。ここで、スキージには、溝の両側のエッジに押し当てることで塗布液の溝外への漏れ出しを防止する漏れ防止面を設けているので、スキージで押し拡げられた塗布液が溝のエッジを越えて外側に漏れ出そうとしても、その塗布液がスキージの漏れ防止面で止められ、溝の外側に漏れ出すことはなく、このため、溝内面を、溝のエッジまできれいに、見栄えよく塗装することができる。また、本発明では、溝内面及び板材表面全域を塗装し、その後板材表面の塗膜を除去するという工程を用いていないので、板材表面の塗膜除去という面倒な作業が不要となり、溝塗装装置を簡略化できると共に、表面にエンボス加工を施した板材に対しても支障なく、溝塗装を行うことができる。   According to the apparatus of the present invention, the coating liquid is continuously supplied to the groove of the grooved plate material by the dispenser nozzle, and the coating liquid is spread on the entire area of the groove inner surface with a squeegee, thereby coating the inner surface of the groove. Can be applied. Here, the squeegee is provided with a leakage prevention surface that prevents the coating liquid from leaking out of the groove by pressing against the edges on both sides of the groove. Even if it is about to leak outside, the coating liquid is stopped by the leakage prevention surface of the squeegee and does not leak to the outside of the groove. Therefore, the groove inner surface is painted neatly up to the edge of the groove. can do. Further, in the present invention, since the process of painting the groove inner surface and the entire surface of the plate material and then removing the coating film on the plate material surface is not used, the troublesome work of removing the coating film on the plate material surface becomes unnecessary, and the groove coating apparatus In addition, the groove coating can be performed without hindrance to the plate material whose surface is embossed.

ここで、前記スキージの、溝内の塗布液に接する部分に、塗布液を通すための通路とそれにつながる塗布液溜まりを設けておくと、スキージを溝に沿って移動させ、溝内の塗布液を押し拡げて行く際にそのスキージの前に溜まってゆく過剰な塗布液の一部が塗布液溜まりに収容されるため、スキージの前に溜まってゆく過剰な塗布液の増加を抑制でき、このため、スキージの前の塗布液量が過大となって溝の外側に押し出されてしまうということを防止でき、長尺の溝付板材の溝に対しても全長に渡って、溝内面を、溝のエッジまできれいに、見栄えよく塗装することができる。   Here, if a passage for passing the coating liquid and a coating liquid reservoir connected thereto are provided in a portion of the squeegee that contacts the coating liquid in the groove, the squeegee is moved along the groove to apply the coating liquid in the groove. When expanding the squeegee, a part of the excess coating solution that accumulates in front of the squeegee is contained in the coating solution reservoir, so that an increase in excess coating solution that accumulates in front of the squeegee can be suppressed. Therefore, it is possible to prevent the amount of the coating liquid before the squeegee from being excessively pushed out of the groove, and the inner surface of the groove over the entire length of the groove of the long grooved plate material It can be painted neatly and beautifully up to the edges.

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4a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 4a 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)はこの溝塗装装置に用いているスキージを、図4のA−A方向に見た概略断面図、図5(b)はそのスキージを図5(a)のB−B方向に見た概略断面図、図6(a)、(b)、(c)、(d)は図3、4に示す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、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9等を備えている。ここで、ディスペンサノズル8及びスキージ9は定位置に配置されているが、溝付板材1が溝4に平行方向に移動するので、ディスペンサノズル8及びスキージ9は溝4に対して相対的に移動することとなる。従って、この実施の形態では溝付板材1を搬送する搬送手段7が、ディスペンサノズル及びスキージを、溝付板材の溝に対して相対的に移動させる手段を構成する。なお、ディスペンサノズル及びスキージを、溝付板材の溝に対して相対的に移動させる手段は、この構成に限らず、溝付板材を停止させておき、その溝付板材の溝に沿って、ディスペンサノズル及びスキージを移動させる構成としてもよい。   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. FIG. 5A is a schematic cross-sectional view of the squeegee used in this groove coating apparatus as seen in the direction AA in FIG. 4, and FIG. 5B is the squeegee in the direction BB in FIG. 6 (a), 6 (b), 6 (c), and 6 (d) are schematic sectional views showing a state in which the inner surface of the groove is applied by the groove coating apparatus shown in FIGS. . 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 grooves 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. The coating liquid supply device (not shown) provided and the grooved plate 1 in the running direction of the grooved plate 1 are disposed downstream of the dispenser nozzle 8 so as to face the groove 4, and the coating liquid 13 supplied into the groove 4 is disposed on the groove inner surface. A squeegee 9 and the like are provided. Here, although the dispenser nozzle 8 and the squeegee 9 are disposed at fixed positions, the dispenser nozzle 8 and the squeegee 9 move relative to the groove 4 because the grooved plate 1 moves in the direction parallel to the groove 4. Will be. Therefore, in this embodiment, the conveying means 7 for conveying the grooved plate material 1 constitutes a means for moving the dispenser nozzle and the squeegee relative to the groove of the grooved plate material. The means for moving the dispenser nozzle and the squeegee relative to the groove of the grooved plate material is not limited to this configuration, and the grooved plate material is stopped, and the dispenser is disposed along the groove of the grooved plate material. It is good also as a structure which moves a nozzle and a squeegee.

ディスペンサノズル8には、その先端を経て溝4内に挿入されるように、ピアノ線などの補助ガイド10が取り付けられている。この補助ガイド10は、ディスペンサノズル8がら吐出された塗布液がその補助ガイド10を伝って溝4内に供給されるように案内するためのものである。この補助ガイド10を設けたことで、ディスペンサノズル8からの塗布液が安定して溝4内に流入し、また、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、走行中の溝付板材1の溝4が横方向に多少ずれたとしても、補助ガイド10は溝4内に挿入された状態に保たれるので、塗布液13が溝4の外側にはみ出すことがなく、溝4内に良好に供給されることとなる。なお、補助ガイド10としてはピアノ線などの線材に限らず、V字状断面、U字状断面等の樋状の材料を用いてもよい。また、補助ガイド10がなくても、ディスペンサノズル8から溝4内に塗布液を良好に供給できる場合には、補助ガイド10は省略してもよい。   An auxiliary guide 10 such as a piano wire is attached to the dispenser nozzle 8 so as to be inserted into the groove 4 through its tip. The auxiliary guide 10 is for guiding the coating liquid discharged from the dispenser nozzle 8 so as to be supplied into the groove 4 through the auxiliary guide 10. By providing the auxiliary guide 10, the coating liquid from the dispenser nozzle 8 stably flows into the groove 4, and the grooved plate material that is running is provided to the dispenser nozzle 8 that is attached at a fixed position. Even if one groove 4 is slightly displaced in the lateral direction, the auxiliary guide 10 is kept inserted in the groove 4, so that the coating liquid 13 does not protrude outside the groove 4, It will be supplied satisfactorily. The auxiliary guide 10 is not limited to a wire such as a piano wire, but may be a bowl-shaped material such as a V-shaped cross section or a U-shaped cross section. Further, even if the auxiliary guide 10 is not provided, the auxiliary guide 10 may be omitted when the coating liquid can be satisfactorily supplied from the dispenser nozzle 8 into the groove 4.

スキージ9は、支持軸15に保持されたアーム16とその先端に取り付けられたスキージ本体17を備えている。アーム16は板ばねで形成されており、そのばね力を利用してスキージ本体17を溝付板材1上面の溝形成領域に適切な押圧力で押し付けるようになっている。なお、アーム16に板ばねを用い、そのばね力を用いてスキージ本体17を溝付板材1に押し付ける代わりに、アーム16を剛性を持った部材で形成し、支持軸15に適当なトルクを加え、そのトルクによってスキージ本体17を溝付板材1に適切な押圧力で押し付ける構成としてもよい。ただし、アーム16に板ばねを用いた方が、スキージ本体17を全長に渡って均一に溝付板材1の溝形成領域に押し付けることができるので好ましい。   The squeegee 9 includes an arm 16 held by a support shaft 15 and a squeegee body 17 attached to the tip of the arm 16. The arm 16 is formed of a leaf spring, and the squeegee body 17 is pressed against the groove forming region on the upper surface of the grooved plate member 1 with an appropriate pressing force using the spring force. Instead of using a leaf spring for the arm 16 and pressing the squeegee body 17 against the grooved plate 1 using the spring force, the arm 16 is formed of a rigid member and an appropriate torque is applied to the support shaft 15. The squeegee main body 17 may be pressed against the grooved plate member 1 with an appropriate pressing force by the torque. However, it is preferable to use a leaf spring for the arm 16 because the squeegee body 17 can be uniformly pressed against the groove forming region of the grooved plate 1 over the entire length.

スキージ本体17は、溝4の幅よりも広い幅を有すると共に下面に、下方が凸状となるように傾斜した一対の傾斜面17a、17aを有し、全体が五角柱状のものである。この構成により、図6(b)から良く分かるように、スキージ本体17を溝4に押し付けた際、一対の傾斜面17a、17aが溝4の両側のエッジ4a、4aに押し当てられて溝4の上面開口を閉じ、溝4内の塗布液13が溝4の両側のエッジ4a、4aを越えて溝の外に漏れ出すのを防止することができる。すなわち、一対の傾斜面17a、17aは、溝の両側のエッジに押し当てることで塗布液の溝外への漏れ出しを防止する漏れ防止面として作用する。一対の傾斜面17a、17aの傾斜角度は、一対の傾斜面17a、17aを溝4のエッジに押し当てた状態において、スキージ本体17を溝4に沿って移動させることによりスキージ本体17の溝4内に入り込んでいる部分が、溝4内の塗布液13を溝内面全域に押し拡げることができるように定められている。図5から良く分かるように、スキージ本体17には、溝内の塗布液に接する部分に、塗布液を通すための通路18とそれにつながる塗布液溜まり19が設けられている。この通路18及び塗布液溜まり19は、スキージ本体17を溝4に沿って移動させ、溝4内の塗布液を押し拡げて行く際にそのスキージの前に溜まってゆく過剰な塗布液の一部が内部の塗布液溜まり19に一時的に収容されるように設けたものである。なお、図示は省略しているが、塗布液溜まり19に容易に塗布液が入ることができるよう、空気孔が形成されている。スキージ本体19は、金属、プラスチック、ゴム等によって作られる。   The squeegee main body 17 has a width wider than the width of the groove 4 and has a pair of inclined surfaces 17a and 17a inclined on the lower surface so as to be convex downward, and is entirely pentagonal. 6B, when the squeegee main body 17 is pressed against the groove 4, the pair of inclined surfaces 17a and 17a are pressed against the edges 4a and 4a on both sides of the groove 4 so that the groove 4 It is possible to prevent the coating liquid 13 in the groove 4 from leaking out of the groove beyond the edges 4 a and 4 a on both sides of the groove 4. That is, the pair of inclined surfaces 17a and 17a act as a leakage preventing surface that prevents the coating liquid from leaking out of the groove by pressing against the edges on both sides of the groove. The inclination angle of the pair of inclined surfaces 17 a, 17 a is determined by moving the squeegee body 17 along the groove 4 in the state where the pair of inclined surfaces 17 a, 17 a is pressed against the edge of the groove 4. The portion entering the inside is determined so that the coating liquid 13 in the groove 4 can be spread over the entire inner surface of the groove. As can be seen from FIG. 5, the squeegee main body 17 is provided with a passage 18 for passing the coating solution and a coating solution reservoir 19 connected to the passage 18 in the portion in contact with the coating solution in the groove. The passage 18 and the coating liquid reservoir 19 move a part of the squeegee main body 17 along the groove 4 and a part of the excessive coating liquid that accumulates in front of the squeegee when the coating liquid in the groove 4 is expanded. Is temporarily stored in the coating liquid reservoir 19 inside. Although not shown, air holes are formed so that the coating liquid can easily enter the coating liquid reservoir 19. The squeegee body 19 is made of metal, plastic, rubber or the like.

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。図3、図4において、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、その溝付板材1の走行中にまず、図4、図6(a)に示すように、溝付板材1の溝4内にディスペンサノズル8が塗布液13を連続的に定量供給する。この際、吐出された塗布液は補助ガイド10を伝って溝4内に流れ込むため、溝4の外側に漏れ出し、周辺の汚すことはない。次に、図4、図6(b)に示すように、その塗布液13をスキージ9のスキージ本体17が溝4の内面に押し拡げて行く。この際、押し拡げられた塗布液13が溝内面に沿って上昇し、エッジ4a、4aを越えようとすることがあるが、そのエッジ4a、4aにはスキージ本体17の一対の傾斜面17a、17aが押し当てられているので、塗布液13がそのエッジ4a、4aを越えて外側に漏れ出すことはない。かくして、図4、図6(c)に示すように溝4内の塗布液13が溝外側に拡がることなく、溝4のエッジ4a、4aに到るまでの内面全域に押し拡げられる。ところで、一般に、スキージを溝4に沿って相対的に移動させて塗布液を押し拡げてゆく際、そのスキージの進行方向の前には塗布液の溜まりが生じ、その溜まり量が徐々に増加してゆき、長い溝の場合には溝のエッジを越えて外側に漏れ出すことがあるが、この実施の形態で用いているスキージ本体17は、通路18及び塗布液溜まり19を備えているので、塗布液の一部が塗布液溜まり19の中に一時的に収容され、これにより、スキージ本体17の前の塗布液溜まりの増加を抑制できる。かくして、長い溝4に対して塗装を行っても、塗布液が溝4の外側に漏れ出すことはない。   Next, the painting operation by the groove coating apparatus 6 having the above configuration will be described. 3 and 4, when the grooved plate 1 is continuously conveyed by the conveying means 7, first, as shown in FIGS. 4 and 6 (a), while the grooved plate 1 is traveling, The dispenser nozzle 8 continuously supplies the coating liquid 13 into the groove 4 of the grooved plate 1 continuously. At this time, since the discharged coating liquid flows into the groove 4 through the auxiliary guide 10, it leaks to the outside of the groove 4 and does not stain the surroundings. Next, as shown in FIGS. 4 and 6 (b), the squeegee body 17 of the squeegee 9 spreads the coating liquid 13 on the inner surface of the groove 4. At this time, the spread coating liquid 13 may rise along the inner surface of the groove and try to exceed the edges 4a and 4a. The edges 4a and 4a have a pair of inclined surfaces 17a and 17a, Since 17a is pressed, the coating liquid 13 does not leak outside the edges 4a and 4a. Thus, as shown in FIGS. 4 and 6C, the coating liquid 13 in the groove 4 is spread over the entire inner surface until reaching the edges 4 a and 4 a of the groove 4 without spreading outside the groove. By the way, in general, when the squeegee is relatively moved along the groove 4 to spread the coating liquid, the coating liquid pools before the squeegee travels, and the pool amount gradually increases. In the case of a long groove, it may leak out beyond the edge of the groove, but the squeegee body 17 used in this embodiment has a passage 18 and a coating liquid reservoir 19, A part of the coating liquid is temporarily stored in the coating liquid reservoir 19, whereby an increase in the coating liquid reservoir in front of the squeegee body 17 can be suppressed. Thus, even if the long groove 4 is coated, the coating liquid does not leak to the outside of the groove 4.

スキージ9が塗布液13を溝4の内面全域に押し拡げた後、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6(d)に示すように、溝4の内面全域に塗膜14が形成される。以上により、溝4の内面が全長に渡って一定幅で見栄えよく塗装される。なお、スキージ本体17の塗布液溜まり19の中に一時的に収容された塗布液は、適当な時期に除去すればよい。また、塗布液溜まり19に吸引管を接続しておき、常時、或いは適当なタイミングで吸引、除去する構成としてもよい。   After the squeegee 9 pushes the coating solution 13 over the entire inner surface of the groove 4, the coating solution 13 pushed over the inner surface of the groove 4 is dried. Thereby, as shown in FIG. 6D, the coating film 14 is formed on the entire inner surface of the groove 4. As described above, the inner surface of the groove 4 is painted with a certain width over the entire length. In addition, what is necessary is just to remove the coating liquid temporarily accommodated in the coating liquid reservoir 19 of the squeegee main body 17 at an appropriate time. Further, a suction pipe may be connected to the coating liquid reservoir 19 and suction or removal may be performed constantly or at an appropriate timing.

上記の実施の形態に用いたスキージ本体17は、その全長に渡って、外形を同一としているが、本発明に用いるスキージ本体17の形状はこれに限らず、溝の両側のエッジに押し当てることで塗布液の溝外への漏れ出しを防止する漏れ防止面を備え且つ溝に沿って移動することで溝内の塗布液を溝内面全域に押し拡げることができるものであれば、適宜変更可能である。図7はスキージ本体の変形例を示すものである。図7に示すスキージ本体17Aは、図5に示すスキージ本体17と同様に、下面に一対の傾斜面17a、17aを備えているが、スキージ本体17とは異なり、その一対の傾斜面17a、17aが交差する領域(幅方向の中央領域)で且つ溝に対する進行方向に関して前側となる領域に端部に向かって斜め上方に傾斜した中央傾斜面17bを形成している。この構成とすると、スキージ本体17Aを溝に沿って移動させて溝内の塗布液を押し拡げる際、スキージ本体17Aの前面と中央傾斜面17bとで塗布液を押し拡げることとなり、押し拡げられた塗布液が溝のエッジに到達する位置は、スキージ本体17Aの前面よりもかなり後ろの位置となり、このため、スキージ本体17Aの前で塗布液がエッジを越えて外側に漏れ出すということがなく、溝のエッジに押し当てている一対の傾斜面17a、17aで塗布液の溝の外側への流出を一層確実に防止できるという利点が得られる。図8はスキージ本体の更に他の変形例を示すものである。図8に示すスキージ本体17Bでは、一対の傾斜面17a、17aが交差する領域(幅方向の中央領域)で且つ溝に対する進行方向に関して前側となる領域に平坦面17cを形成し、その後ろに垂直な面17dを形成している。この構成とすると、スキージ本体17Bを溝に沿って移動させて溝内の塗布液を押し拡げる際、スキージ本体17Bの前面と中間の垂直な面17dとが塗布液を押し拡げることとなり、この場合にも図7のスキージ本体17Aと同様に、押し拡げられた塗布液が溝のエッジに到達する位置は、スキージ本体17Bの前面よりもかなり後ろの位置となり、このため、スキージ本体17Bの前で塗布液がエッジを越えて外側に漏れ出すということがなく、溝のエッジに当接している一対の傾斜面17a、17aで塗布液の溝の外側への流出を一層確実に防止できるという利点が得られる。   The squeegee main body 17 used in the above embodiment has the same outer shape over its entire length, but the shape of the squeegee main body 17 used in the present invention is not limited to this and is pressed against the edges on both sides of the groove. As long as it has a leak-proof surface that prevents the coating liquid from leaking out of the groove and can move along the groove, the coating liquid in the groove can be spread over the entire inner surface of the groove. It is. FIG. 7 shows a modification of the squeegee body. The squeegee main body 17A shown in FIG. 7 includes a pair of inclined surfaces 17a and 17a on the lower surface, like the squeegee main body 17 shown in FIG. 5, but unlike the squeegee main body 17, the pair of inclined surfaces 17a and 17a. A central inclined surface 17b that is inclined obliquely upward toward the end portion is formed in a region that intersects with each other (a central region in the width direction) and a region that is on the front side in the traveling direction with respect to the groove. With this configuration, when the squeegee body 17A is moved along the groove to spread the coating liquid in the groove, the coating liquid is pushed and spread between the front surface of the squeegee body 17A and the central inclined surface 17b. The position where the coating liquid reaches the edge of the groove is a position considerably behind the front surface of the squeegee main body 17A. Therefore, the coating liquid does not leak beyond the edge in front of the squeegee main body 17A. An advantage is obtained in that the outflow of the coating liquid to the outside of the groove can be more reliably prevented by the pair of inclined surfaces 17a and 17a pressed against the edge of the groove. FIG. 8 shows still another modification of the squeegee body. In the squeegee body 17B shown in FIG. 8, a flat surface 17c is formed in a region where the pair of inclined surfaces 17a and 17a intersect (a central region in the width direction) and on the front side with respect to the traveling direction with respect to the groove, and is perpendicular to the rear side. A flat surface 17d is formed. With this configuration, when the squeegee body 17B is moved along the groove to spread the coating liquid in the groove, the front surface of the squeegee body 17B and the intermediate vertical surface 17d spread the coating liquid. In addition, similarly to the squeegee body 17A in FIG. 7, the position where the spread coating solution reaches the edge of the groove is a position considerably behind the front surface of the squeegee body 17B. There is an advantage that the coating liquid does not leak to the outside beyond the edge, and the outflow of the coating liquid to the outside of the groove can be more reliably prevented by the pair of inclined surfaces 17a and 17a contacting the edge of the groove. can get.

上記した実施の形態ではいずれも、スキージ本体17、17A、17Bに通路18及び塗布液溜まり19を設け、スキージ本体17、17A、17Bの前に溜まる塗布液量の増加を抑制する構成としているが、塗布液溜まり19を省略し、通路18のみで塗布液を一時的に収容する構成とするとか、通路18に吸引管を接続し、外部に吸引、除去する構成としてもよく、更には、塗装対象の溝4の長さが短くてスキージ本体17、17A、17Bの前に溜まる塗布液が問題とならない場合などには、通路18及び塗布液溜まり19は省略してもよい。   In any of the above-described embodiments, the passage 18 and the coating liquid reservoir 19 are provided in the squeegee main bodies 17, 17A, 17B to suppress an increase in the amount of the coating liquid accumulated in front of the squeegee main bodies 17, 17A, 17B. The coating liquid reservoir 19 may be omitted, and the coating liquid may be temporarily stored only by the passage 18, or the suction pipe may be connected to the passage 18 to be sucked and removed to the outside. When the length of the target groove 4 is short and the coating liquid collected in front of the squeegee bodies 17, 17 </ b> A, 17 </ b> B does not matter, the passage 18 and the coating liquid reservoir 19 may be omitted.

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9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、まず、ディスペンサノズル8を溝4Aに沿って移動させながら塗布液を供給し、次いで、スキージ9を溝4Aに沿って移動させて塗布液を押し拡げる方法を採ることが、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. 9, 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 can be applied. In coating the groove 4A, the grooved plate 1A is stopped, first, the coating liquid is supplied while moving the dispenser nozzle 8 along the groove 4A, and then the squeegee 9 is moved along the groove 4A. It is preferable to adopt a method of spreading the coating liquid to allow the coating to be efficiently applied to the short grooves 4A.

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.
