Abstract

PROBLEM TO BE SOLVED: To provide a method of manufacturing a decorative material for enabling the decorative material to be different in surface design and material quality between both sides of its corner in a freely selective manner.SOLUTION: Side faces 12a, 14a of first and second plate materials 12, 14 mutually different in surface design abut each other in the state that their surfaces are flush with each other. While they are kept in an abutting condition, a V-shaped groove 20 is formed ranging from the reverse to the surfaces of both plate materials 12, 14 or close to the front sides thereof in the state that a groove bottom 20a of an abutment surface 22 corresponds to the abutment surface 22 between the first and second plate materials 12, 14. An adhesive 36 is adhered to the groove 20 and then the groove 20 is closed to fix the plate materials 12, 14 to each other, thus solving the above issue.

Description

本発明は、住宅等の建築物における框、踏板、幅木、ドア等に使用される化粧材の製造方法に関する。   The present invention relates to a method for producing a decorative material used for a fence, a step board, a skirting board, a door and the like in a building such as a house.

以前から、様々な態様の住宅等の建築物における框、踏板、幅木、ドア等に使用される化粧材が開発されており、例えば、特許文献1には、図11(a)に示すように、1枚の板材1の表面に、ポリエステル等を原料とする不織布や合成樹脂シート等の可撓性シート2を貼着し、さらに当該可撓性シート2の表面に、天然木を薄板化した突板等を表面材3として貼着するとともに、板材1の裏面(可撓性シート2等が貼着された面とは反対側の面)側から可撓性シート2に向けて底部がV字状の切欠溝4が形成された化粧材5(折り曲げ加工前)が開示されている。   For some time, decorative materials used for eaves, footboards, skirting boards, doors, etc. in buildings of various forms such as houses have been developed. For example, Patent Document 1 discloses as shown in FIG. In addition, a flexible sheet 2 such as a non-woven fabric or synthetic resin sheet made of polyester or the like is pasted on the surface of a single sheet material 1, and the natural wood is thinned on the surface of the flexible sheet 2. While sticking the projected plate etc. as the surface material 3, the bottom is V toward the flexible sheet 2 from the back surface of the plate material 1 (the surface opposite to the surface on which the flexible sheet 2 or the like is adhered). A decorative material 5 (before bending) in which a letter-shaped cutout groove 4 is formed is disclosed.

そして、図11(b)に示すように、可撓性シート2をガイドにして切欠溝4を閉じるように折り曲げ加工して化粧材5を形成していた。また、複雑な形状の切欠溝4を形成して折り曲げ加工を行うことにより、図12に示すような棒状材を形成していた。   Then, as shown in FIG. 11 (b), the decorative sheet 5 is formed by bending the flexible sheet 2 as a guide so as to close the notch groove 4. Further, a bar-shaped material as shown in FIG. 12 is formed by forming a notch groove 4 having a complicated shape and performing a bending process.

実開昭54−109317号公報Japanese Utility Model Publication No. 54-109317

しかしながら、従来技術の化粧材5では、可撓性シート2および表面材3も含めて折り曲げ加工を行うことから、表面材3としては、当該折り曲げ加工に耐えることのできる程度の可撓性を有する材料を選択しなければならず、材料選択の幅が狭いという問題があった。   However, since the decorative material 5 of the prior art performs the bending process including the flexible sheet 2 and the surface material 3, the surface material 3 is flexible enough to withstand the bending process. There was a problem that the material had to be selected and the range of material selection was narrow.

また、近年、大径木の供給が減少しており、1枚物の木質化粧単板の供給が難しくなっていることから、框のように天面と側面との意匠(表面柄)を異ならせたいような場合には、例えば表面側に異なる意匠(表面柄)の表面材3(印刷シートや突板など)が隣接して設けられた表面材3を持つ板材1を用意し、この板材1の裏面側から前記意匠の境界線にV溝カット用回転鋸の刃先を裏面側から正確に一致させ、表面材3を残して裏面から切欠溝4を形成し、然る後、切欠溝4で折り曲げて接着するようにして製造せざるを得なかった。しかしながら、裏面側から表面側の意匠の境界線にV溝カット用刃物の先端を正確に一致させることは非常に時間が掛かり、生産性を落とすという問題があった。   In recent years, the supply of large-diameter trees has decreased, and it has become difficult to supply a single wood veneer veneer, so if the design (surface pattern) of the top and side surfaces is different, like a kite. In such a case, for example, a plate material 1 having a surface material 3 provided with a surface material 3 (printing sheet, protruding plate, etc.) of a different design (surface pattern) adjacent to the surface side is prepared. From the back side, the cutting edge of the V-groove cutting rotary saw is precisely aligned with the boundary line of the design from the back side, leaving the surface material 3 to form the notch groove 4 from the back side, and then bending at the notch groove 4 It had to be manufactured in such a way as to adhere. However, it has been very time-consuming to accurately match the tip of the V-groove cutting tool with the boundary line of the design from the back side to the front side, resulting in a problem of reducing productivity.

その他、1枚物の板材1にVカットすることになるので、切欠溝4の両側は当然同じ板厚であり、例えば、天面と側面とで板厚を変えたいというような要望に対して、切欠溝4の両側で板厚を変えるというようなことは望むべくもなかった。   In addition, since the V-cut is made to the single plate material 1, both sides of the cutout groove 4 are naturally the same plate thickness. For example, in response to a request to change the plate thickness between the top surface and the side surface. There was no way to change the thickness on both sides of the notch groove 4.

本発明は、このような従来技術の問題点に鑑みて開発されたものである。それゆえに本発明の主たる課題は、生産性良く、角部の両側で表面柄や材質を自由に選択して異ならせることができる化粧材の製造方法を提供することにある。   The present invention has been developed in view of such problems of the prior art. Therefore, a main object of the present invention is to provide a method for manufacturing a cosmetic material that can be selected and made different in surface pattern and material on both sides of a corner with good productivity.

The invention described in claim 5 relates to an improvement in the method for manufacturing the decorative material 10 according to any one of claims 1 to 4,
“Before contacting the first and second plate members 12, 14, a tapered surface 60 that forms an acute angle with the surface of the plate member 12 is formed on at least one side surface 12 a of both plate members 12, 14. Features.

両板材12、14の側面12a、14aを互いに当接させる際、両側面12a、14a間に異物等のゴミ噛みがあると、両板材12、14の表面同士が正しく当接しない(すなわち、離間した)状態のままでV字状の溝20が形成されて不良が生じてしまい生産性を落とす原因となるが、本発明によれば、両板材12、14における少なくとも一方の側面12aに、当該板材12の表面と鋭角を成すテーパー面60が形成されているので、両板材12、14の側面12a、14a間に異物等が存在しても、両板材12、14を互いに当接させる際に当該異物等を逃がすことにより、両板材12、14の表面同士を正確に当接させることができ、不良の発生を抑えて生産歩留まりを飛躍的に向上させることができる。   When the side surfaces 12a and 14a of the two plate members 12 and 14 are brought into contact with each other, if there is a foreign object such as foreign matter between the two side surfaces 12a and 14a, the surfaces of the two plate members 12 and 14 do not come into contact with each other correctly (i.e., spaced apart). However, according to the present invention, the V-shaped groove 20 is formed in a state where the V-shaped groove 20 is formed and the productivity is reduced. Since the taper surface 60 that forms an acute angle with the surface of the plate material 12 is formed, even when foreign matter or the like is present between the side surfaces 12a and 14a of the both plate materials 12 and 14, the two plate materials 12 and 14 are brought into contact with each other. By letting out the foreign matter or the like, the surfaces of both plate members 12 and 14 can be brought into contact with each other accurately, and the production yield can be dramatically improved by suppressing the occurrence of defects.

請求項6に記載した発明は、請求項1ないし5のいずれかに記載した化粧材10の製造方法の改良に関し、
「前記第1板材12の側面12aと前記第2板材14の側面14aとを互いに当接させた後、両板材12、14の当接面22に形成された前記溝20を閉じるまでの間に、
前記第1板材12から前記第2板材14にかけての表面に可撓性を有するテープ材28を貼り付け、
両板材12、14を互いに固着させた後、前記テープ材28を剥がす」ことを特徴とする。
The invention described in claim 6 relates to an improvement in the method for manufacturing the decorative material 10 according to any one of claims 1 to 5,
“After the side surface 12a of the first plate member 12 and the side surface 14a of the second plate member 14 are brought into contact with each other, the groove 20 formed on the contact surface 22 of the both plate members 12 and 14 is closed. ,
A tape material 28 having flexibility is applied to the surface from the first plate material 12 to the second plate material 14,
After the two plate members 12, 14 are fixed to each other, the tape member 28 is peeled off. "

この発明によれば、テープ材28をガイドにして折り曲げたとき、折り曲げ部分の表面側端を互いに密接させる方向の押圧力がテープ材28の伸ばされた部分に生じる。特に、V字状の溝20が表面に達して各板材12、14の先端が薄くなっている場合により効果的である。また、テープ材28は、溝20に付着させた接着剤36が表面にはみ出すのを防止する役割も有している。このように、テープ材28を用いることにより、各板材12、14の先端部同士が精度良く一致した見栄えのよい化粧材10を製造することができる。   According to the present invention, when the tape material 28 is bent as a guide, a pressing force is generated in the stretched portion of the tape material 28 in a direction in which the surface side ends of the bent portions are brought into close contact with each other. In particular, it is more effective when the V-shaped groove 20 reaches the surface and the tips of the plate members 12 and 14 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to the groove 20 from protruding to the surface. In this way, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the end portions of the plate materials 12 and 14 are accurately matched.

請求項7に記載した発明は、請求項6に記載した化粧材10の製造方法の改良に関し、
「前記テープ材28の貼り付けは、互いに当接された前記第1板材12の表面と前記第2板材14の表面とが鈍角を成す状態で行われ、
前記テープ材28を貼り付けた後、両板材12、14の当接角度がより大きくなるように広げてから、前記溝20、30、32を形成する」ことを特徴とする。
The invention described in claim 7 relates to an improvement of the manufacturing method of the decorative material 10 described in claim 6,
“Attaching the tape material 28 is performed in a state where the surface of the first plate material 12 and the surface of the second plate material 14 in contact with each other form an obtuse angle,
After affixing the tape material 28, the grooves 20, 30, 32 are formed after the plate material 12, 14 is expanded so that the contact angle between the two plate materials 12, 14 becomes larger. "

本発明によれば、第1板材12の表面と第2板材14の表面とが鈍角(90度より大きく、180度より小さい角度)を成す状態で両板材12、14の当該表面に貼り付けられたテープ材28には、両板材12、14の当接角度がより大きくなるように両板材12、14が広げられて伸ばされたときに、縮もうとする力が生じる。この収縮力によって両板材12、14がより強く押し合わされるので、両板材12、14の先端部同士がさらに精度良く一致し、より見栄えの良い化粧材10を製造することができる。   According to the present invention, the surface of the first plate member 12 and the surface of the second plate member 14 are attached to the surfaces of the two plate members 12 and 14 in an obtuse angle (an angle larger than 90 degrees and smaller than 180 degrees). The tape material 28 has a force to shrink when both the plate materials 12 and 14 are extended and extended so that the contact angle between the both plate materials 12 and 14 becomes larger. Since both the board | plate materials 12 and 14 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 14 correspond more accurately, and the cosmetics 10 with a more attractive appearance can be manufactured.

請求項8に記載した発明は、請求項2または4に記載の化粧材10の製造方法の改良に関し、
「前記第1板材12および前記第2板材14は、前記表面材18a、18bとして予め前記基材13、15の表面に取り付けられたインク受容層を有する紙に、インクジェット印刷によって所望の表面柄が形成されたものである」ことを特徴とする。
The invention described in claim 8 relates to an improvement in the method for manufacturing the decorative material 10 according to claim 2 or 4,
“The first plate member 12 and the second plate member 14 have a desired surface pattern by ink jet printing on paper having an ink receiving layer that is attached to the surfaces of the base members 13 and 15 in advance as the surface members 18a and 18b. It is formed ".

請求項9に記載した発明は、請求項8に記載の化粧材10の製造方法の改良に関し、
「インクジェット印刷された前記紙の表面には透明塗料が塗布されている」ことを特徴とする。
The invention described in claim 9 relates to an improvement in the manufacturing method of the decorative material 10 according to claim 8,
“A transparent paint is applied to the surface of the ink-jet printed paper”.

一般的な印刷シートは、輪転機印刷された、数千〜数万m単位の印刷ロットを必要とする。壁材や床材等の大面積を施工する製品に利用する場合であれば、このように印刷ロットが大きくても問題ないが、框、踏板、幅木等のように施工面積の小さな化粧材に印刷シートを使用する場合、印刷ロットが大きいものについては、多種類の表面柄を準備しておくことができず、選択の自由度がなかった。とりわけ、面取り部34に使用する絵柄は使用量が少ないことから、上述した印刷ロットの問題が顕著であった。   A general printing sheet requires printing lots of thousands to tens of thousands of meters printed on a rotary press. If it is used for products with large areas such as wall materials and flooring, there is no problem even if the printing lot is large in this way, but cosmetics with a small construction area such as fences, treads, baseboards, etc. In the case of using a printing sheet for a large number of printing lots, it was not possible to prepare many kinds of surface patterns and there was no freedom of selection. In particular, since the pattern used for the chamfered portion 34 has a small amount of use, the above-mentioned problem of the printing lot is remarkable.

しかしながら、請求項8に記載した発明では、インクジェット印刷を用いて、より小面積(例えば3尺×6尺板単位)で表面材18a、18bの化粧柄を印刷できることから、多種類の表面柄を準備しても在庫リスクが少なく、自由度の大きな製品設計が可能になる。   However, in the invention described in claim 8, since the decorative patterns of the surface materials 18a and 18b can be printed in a smaller area (for example, in units of 3 × 6 plates) using ink jet printing, various types of surface patterns can be printed. Even if it is prepared, there is little inventory risk and it is possible to design a product with a high degree of freedom.

加えて、予め化粧柄が形成された表面材18a、18bを両基材13、15に貼着する場合、当該表面材を貼着する接着剤が固化するまでの間の養生を必要とするため、生産性がどうしてもあがらないという問題があった。   In addition, when the surface materials 18a and 18b on which the decorative pattern is formed are pasted on both the base materials 13 and 15, curing is required until the adhesive for pasting the surface materials is solidified. There was a problem that productivity was never improved.

しかし、インク受容層を有する紙を予め両基材13、15の表面に貼着一体化しておき、必要に応じて印刷を行うことにより、上述したような養生期間が不要となるので、短納期で化粧材を生産することが可能となる。   However, since the paper having the ink receiving layer is pasted and integrated on the surfaces of the base materials 13 and 15 in advance and printing is performed as necessary, the curing period as described above becomes unnecessary, so that the short delivery time Makes it possible to produce cosmetics.

なお、インクジェット印刷は、一般的な厚板に対する印刷が可能な設備を利用すればよく、耐水性に優れたUV着色インクを利用するのが好ましい。   Ink jet printing may be performed using a facility capable of printing on a general thick plate, and it is preferable to use UV colored ink having excellent water resistance.

また、請求項9に記載したように、インクジェット印刷後、直ちにインクジェット印刷の表面に透明塗料を塗布しておく(下塗り)ことにより、後工程で、テープを貼ったり、溝加工するときの搬送等による傷つきを防ぐことができる。   Further, as described in claim 9, immediately after ink jet printing, a transparent paint is applied to the surface of ink jet printing (undercoating), thereby transporting when applying a tape or grooving in a later step. It can prevent the damage by.

このような透明塗料としては、一般的なアクリル系、ウレタン系等の化粧材用塗料が使用されるが、ホワイトアルミナ、グリーンカーボン等のいわゆる減摩剤を含む下塗り塗料を使用するのが好ましい。もちろん、下塗りした透明塗料の表面にさらに透明塗料を塗布することにより(上塗り)、搬送時等に生じてしまった傷を消すようにしてもよい。   As such a transparent paint, a general paint for acrylic, urethane or the like is used, but an undercoat containing a so-called antifriction agent such as white alumina or green carbon is preferably used. Needless to say, the surface of the undercoated transparent coating may be further coated with a transparent coating (overcoating) so as to erase the scratches generated during transportation.

Moreover, you may use what performed the inkjet printing as needed to the paper provided with the ink receiving layer, or the poly sand paper.

もちろん、表面材18として、DAP含浸紙やメラミン含浸紙等を、接着剤層16を設けることなく両基材13、15の表面に設けてもよい。また、可撓性に乏しい熱硬化性樹脂含浸化粧紙を表面材18として使用することもできる。   Of course, as the surface material 18, DAP-impregnated paper, melamine-impregnated paper, or the like may be provided on the surfaces of the base materials 13 and 15 without providing the adhesive layer 16. Further, a thermosetting resin-impregnated decorative paper having poor flexibility can be used as the surface material 18.

次に、上述した第1板材12および第2板材14を用いて、完成品である「表面材18を有する化粧材10」を中心に、表面材18を用いない場合も含めて、テープ材28を用いることなく製造する手順について説明する。   Next, using the first plate material 12 and the second plate material 14 described above, the tape material 28 including the case where the surface material 18 is not used, centering on the “decorative material 10 having the surface material 18”, which is a finished product. A procedure for manufacturing without using will be described.

まず、接着剤層16を介して互いに表面柄が異なる表面材18a、18bが設けられた第1板材12および第2板材14を用意し(図1(a))、各板材12、14の表面を面一とした状態で第1板材12の側面12aおよび第2板材14の側面14aをそれぞれ突き合わせて当接させる(図1(b))。   First, a first plate member 12 and a second plate member 14 provided with surface members 18a and 18b having different surface patterns are prepared via an adhesive layer 16 (FIG. 1A), and the surfaces of the plate members 12 and 14 are prepared. The side surface 12a of the first plate member 12 and the side surface 14a of the second plate member 14 are abutted and brought into contact with each other (FIG. 1B).

両板材12、14を当接させた後、その当接状態を維持しつつ、両板材12、14の裏面に現れている当接面22に図示しないV字状の回転鋸の刃先を合致させた後、回転鋸で切除して、回転鋸の形状に合致したV字状の溝20を形成する(図1(c))。   After the plate members 12 and 14 are brought into contact with each other, the cutting edge of a V-shaped rotary saw (not shown) is brought into alignment with the contact surface 22 appearing on the back surfaces of the plate members 12 and 14 while maintaining the contact state. After that, it is cut out with a rotary saw to form a V-shaped groove 20 that matches the shape of the rotary saw (FIG. 1C).

この当接状態を維持する手段としては、両板材12、14を完全に固定状態にする方法が考えられる。クランプ、押圧機、大きなのこぎり状の固定具(いわゆるガンギ)等により機械的に固定する方法や、空気吸着、吸着剤を表面に有する吸着具、粘着剤を表面に有する粘着具等の固定手段により固定する方法が挙げられる。ガンギ等の板材表面に傷をつける可能性のある搬送機を使用する場合は、裏面側にガンギを当接させるのがよい。   As a means for maintaining this contact state, a method of completely fixing both plate members 12 and 14 can be considered. By fixing means such as a method of mechanically fixing with a clamp, a pressing machine, a large saw-like fixing tool (so-called gang), air adsorption, an adsorbent having an adsorbent on the surface, an adhesive having an adhesive on the surface, etc. The method of fixing is mentioned. When using a transporter that may damage the surface of the plate material, such as an escape, it is preferable to contact the escape with the back side.

また、さまざまな幅寸法や厚さ寸法に対応するため、エアダンパー、オイルダンパー、バネクッション等を用いて、水平方向及び上下方向の浮き上がりを押さえるのが望ましい。水平方向の押圧力を利用する場合は、両板材12、14を互いに付勢当接させてもよいし、一方の板材における当接側面とは反対の側面をいわゆる定規面とし、当該定規面に押しつけるようにして付勢当接させてもよい。   Further, in order to cope with various width dimensions and thickness dimensions, it is desirable to suppress horizontal and vertical lifting using an air damper, an oil damper, a spring cushion, or the like. When using a horizontal pressing force, both plate members 12 and 14 may be urged against each other, and a side surface opposite to the contact side surface of one plate material is a so-called ruler surface, The urging contact may be made by pressing.

さらに、固定された回転鋸に対して、当接状態を維持しつつ両板材12、14を搬送して溝加工を行ってもよい。この場合、クランプ、押圧機、ガンギ等により機械的に当接させながら搬送する方法や、空気吸着、吸着具、粘着具等の固定手段により当接させながら搬送する方法、あるいは、両板材12、14を、エアダンパー、オイルダンパー、あるいはバネクッション等を用いて、上述したような定規面に付勢当接させながら搬送する方法等を用いてもよい。   Furthermore, it is also possible to carry out grooving by conveying both plate members 12 and 14 while maintaining a contact state with a fixed rotary saw. In this case, a method of conveying while mechanically abutting with a clamp, a pressing machine, an escaper, etc., a method of conveying while abutting with a fixing means such as air adsorption, an adsorber, an adhesive, or the like, For example, a method may be used in which an air damper, an oil damper, a spring cushion, or the like is used to convey 14 while being urged against the ruler surface as described above.

いずれの場合も、溝加工精度を向上させるため、垂直方向の押圧力を利用して切削加工による上下方向のブレを無くすのが好ましい。この場合、できる限り切削加工を行う部分に近い位置を押圧するのが溝加工精度向上の点で好適である。   In any case, in order to improve the groove machining accuracy, it is preferable to eliminate vertical blur due to cutting using a vertical pressing force. In this case, it is preferable to press the position as close as possible to the portion to be cut in order to improve the groove processing accuracy.

溝20は、その溝底部20aが当接面22に一致しており、かつ、両板材12、14を構成する両基材13、15の表面あるいはその手前近傍に至るように(従って、この場合は表面材18の裏面は切削されない。)、または両基材13、15を越えて表面材18の表面(すなわち、両板材12、14の表面)あるいはその手前近傍に至るように形成される(従って、この場合、両板材12、14の表面材18の突合せ端部が切削されて薄くなっている。)。なお、溝20は、上記回転鋸の形状に合致した形状に切削される。   The groove 20 has a groove bottom portion 20a coinciding with the contact surface 22 and reaches the surfaces of the base materials 13 and 15 constituting both plate members 12 and 14 or near the front thereof (therefore, in this case). Is formed so as to reach the surface of the surface material 18 (that is, the surface of the both plate materials 12 and 14) or near the front of the surface material 18 (that is, the surface of the surface material 18 is not cut). Therefore, in this case, the butt end portions of the surface materials 18 of both the plate materials 12 and 14 are cut and thinned. The groove 20 is cut into a shape that matches the shape of the rotary saw.

上述した溝加工は、両板材12、14を当接状態で固定させ、回転鋸を移動させることによって行ってもよいし、逆に、回転鋸を固定回転させ、両板材12、14を当接状態のままで移動させて行うようにしてもよい。   The groove processing described above may be performed by fixing both plate members 12 and 14 in a contact state and moving the rotary saw, or conversely, rotating the rotary saw and rotating both plate members 12 and 14 in contact. You may make it carry out by moving in a state.

なお、溝底部20aの位置を「両板材12、14の表面あるいはその手前近傍」としたのは、溝20の溝底部20aの位置が両板材12、14の表面から突き出さないようにするためであり、溝加工の精度(±0.03mm程度)を考慮して当該位置を両板材12、14の表面からやや裏面側に控えた位置に設定するのが好適である。   The reason why the position of the groove bottom portion 20a is "the surface of both plate members 12, 14 or in the vicinity thereof" is to prevent the position of the groove bottom portion 20a of the groove 20 from protruding from the surfaces of both plate members 12, 14. In consideration of the accuracy of groove processing (about ± 0.03 mm), it is preferable to set the position to a position slightly behind the front surfaces of both plate members 12 and 14.

また、先端部がV字状(本実施例では片刃で45°の鋸刃)に形成された回転鋸を用いて溝20を一回の加工で「V字状の溝」に形成することにより、形成される斜面の角度を正確にすることができ、両板材12、14を接合させたときにおいて接合部位に隙間等のない、美しい接合が可能となる。もちろん、回転鋸に代えて、いわゆるルーター加工機等を使用してもよい。   Further, by forming the groove 20 into a “V-shaped groove” by a single process using a rotary saw whose tip is formed in a V shape (in this embodiment, a 45 ° saw blade with a single blade). The angle of the inclined surface to be formed can be made accurate, and when the two plate members 12 and 14 are joined, a beautiful joining without a gap or the like is possible at the joining portion. Of course, a so-called router machine or the like may be used instead of the rotary saw.

両板材12、14を当接させた状態のまま(この段階においては、表面材18を用いない場合には両板材12、14の表面側端部、または、図示するように、表面材18を用いる場合には表面材18同士が当接した状態になっている。)、溝20の表面にホットメルト系接着剤、PURホットメルト系接着剤、水性ビニルウレタン系接着剤、酢ビ系接着剤、あるいはウレタン系接着剤等の接着剤36を付着させ(図1(d))、然る後、溝20を閉じて両板材12、14を互いに固着させることにより、化粧材10が完成する(図1(e))。   Leave both plate members 12 and 14 in contact with each other (at this stage, if the surface member 18 is not used, the surface side ends of the two plate members 12 and 14 or the surface member 18 as shown in the figure. When used, the surface materials 18 are in contact with each other.), Hot melt adhesive, PUR hot melt adhesive, aqueous vinyl urethane adhesive, vinyl acetate adhesive on the surface of the groove 20 Alternatively, an adhesive 36 such as a urethane adhesive is attached (FIG. 1D), and then the groove 20 is closed and the two plate members 12 and 14 are fixed to each other to complete the decorative material 10 ( FIG. 1 (e)).

なお、接着剤36は、両板材12、14における溝20の両表面に付着させてもよいし、溝20におけるいずれか一方の表面にのみ付着させてもよい。   The adhesive 36 may be attached to both surfaces of the groove 20 in the both plate members 12 and 14, or may be attached to only one surface of the groove 20.

また、両板材12、14は互いに別部材として構成されていることから、これらを固着させて化粧材10を構成しようとするとき、化粧材10の角部26(溝20を閉じた合わせ面の表面側端)から接着剤36が表面にはみ出してくるおそれがある。このような場合、当該接着剤36を両基材13、15の表面の色(表面材18を取り付けない場合)や表面材18の表面の色(表面材18を取り付ける場合)と同色あるいは似た色に着色しておくことにより、はみ出した接着剤36が目立ち難くなるので好適である。   In addition, since both the plate members 12 and 14 are configured as separate members, when the decorative material 10 is formed by fixing them, the corner portion 26 of the decorative material 10 (of the mating surface with the groove 20 closed) is formed. There is a possibility that the adhesive 36 protrudes from the surface side edge). In such a case, the adhesive 36 has the same color as or similar to the surface color of the base materials 13 and 15 (when the surface material 18 is not attached) and the surface color of the surface material 18 (when the surface material 18 is attached). By coloring in color, the protruding adhesive 36 is less noticeable, which is preferable.

また、複数種類の接着剤36を併用してもよい。例えば、水性ビニルウレタン系接着剤は、接着強度に優れるものの、硬化までに少し時間を要することから、接着強度においてやや劣るものの、硬化までの時間が早いPURホットメルト系接着剤と、水性ビニルウレタン系接着剤とを併用することにより、両板材12、14をPURホットメルト系接着剤で先に固着して不所望な位置ずれ等を防止しておき、時間をかけて水性ビニルウレタン系接着剤を硬化させることにより、両板材12、14を位置ずれ無く、かつ、強固に接着させることができる。   A plurality of types of adhesives 36 may be used in combination. For example, water-based vinyl urethane adhesives are excellent in adhesive strength but require a little time to cure, so although they are slightly inferior in adhesive strength, PUR hot-melt adhesives and water-based vinyl urethane are quick in time to cure. In combination with an adhesive, both plate members 12 and 14 are first fixed with a PUR hot melt adhesive to prevent undesired displacement and the like. Is cured, the two plate members 12 and 14 can be firmly bonded without being displaced.

第1板材12および第2板材14は既に述べたように別個の部材であるから、角部26を挟んだ一方の面と他方の面とに使用される各板材12、14の表面柄(意匠)や材質(硬さや板厚等)を互いに異ならせることが可能となる。また、各基材13、15に互いに表面柄が異なる表面材18を使用する場合には、可撓性に乏しい材料を当該表面材18として使用することができる。   Since the first plate member 12 and the second plate member 14 are separate members as described above, the surface patterns (designs) of the plate members 12 and 14 used for one surface and the other surface sandwiching the corner portion 26. ) And materials (hardness, plate thickness, etc.) can be made different from each other. In addition, when the surface material 18 having a different surface pattern is used for each of the base materials 13 and 15, a material having poor flexibility can be used as the surface material 18.

なお、図2に示すように、第1および第2板材12、14を当接させる前段階において、両板材12、14における少なくとも一方の側面(本実施例では、第1板材12の側面12a)に、当該第1板材12の表面と鋭角を成すテーパー面60を形成してもよい。なお、第1板材12の表面とテーパー面60とが成す鋭角は、当該第1板材12の表面と、後に形成されるV字状の溝20による面とが成す角度(鋭角)よりも大きい。なお、テーパー面60を形成する場合、図示するように、両板材12、14の表面側を下向きに配置することになる。   As shown in FIG. 2, at a stage before the first and second plate members 12 and 14 are brought into contact with each other, at least one side surface of both plate members 12 and 14 (in this embodiment, the side surface 12 a of the first plate member 12). In addition, a tapered surface 60 that forms an acute angle with the surface of the first plate member 12 may be formed. The acute angle formed by the surface of the first plate 12 and the tapered surface 60 is larger than the angle (acute angle) formed by the surface of the first plate 12 and the surface formed by the V-shaped groove 20 formed later. In addition, when forming the taper surface 60, the surface side of both board | plate materials 12 and 14 will be arrange | positioned downward so that it may show in figure.

両板材12、14の側面12a、14aを互いに当接させる際、両側面12a、14a間に異物等のゴミ噛みがあると、両板材12、14の表面同士が正しく当接しない(すなわち、離間した)状態のままでV字状の溝20が形成されて不良が生じてしまい生産性を落とす原因となるが、上述のように、テーパー面60を形成することにより、両板材12、14の側面12a、14a間に異物等が存在しても、両板材12、14を互いに当接させる際に当該異物等を逃がすことにより、両板材12、14の表面同士を正確に当接させることができ、不良の発生を抑えて生産歩留まりを飛躍的に向上させることができる。   When the side surfaces 12a and 14a of the two plate members 12 and 14 are brought into contact with each other, if there is a foreign object such as foreign matter between the two side surfaces 12a and 14a, the surfaces of the two plate members 12 and 14 do not come into contact with each other correctly (i.e., spaced apart). In this state, the V-shaped groove 20 is formed and a defect occurs, resulting in a decrease in productivity. However, by forming the tapered surface 60 as described above, Even if there is a foreign object or the like between the side surfaces 12a and 14a, the surfaces of the two plate materials 12 and 14 can be brought into contact with each other accurately by releasing the foreign material or the like when the two plate materials 12 and 14 are brought into contact with each other. It is possible to suppress the occurrence of defects and dramatically improve the production yield.

また、図5に示すように、第1板材12における、テーパー面60が形成された側面12aに対向する反対側の側面12bを定規面62に形成しておき、第1板材12と第2板材14とを当接させる際に、当該定規面62を基準として位置決めした第1板材12におけるテーパー面60が形成された側面12aに、第2板材14の側面14aを押し当ててもよい。   Further, as shown in FIG. 5, the side surface 12 b opposite to the side surface 12 a on which the tapered surface 60 is formed in the first plate material 12 is formed on the ruler surface 62, and the first plate material 12 and the second plate material are formed. When contacting 14, the side surface 14 a of the second plate member 14 may be pressed against the side surface 12 a formed with the tapered surface 60 in the first plate member 12 positioned with reference to the ruler surface 62.

これにより、定規面62を基準として正確に位置決めされた第1板材12に対して第2板材14を正確に当接させることができるので、不良の発生を抑えて生産歩留まりをさらに向上させることができる。   Thereby, since the 2nd board | plate material 14 can be correctly contacted with respect to the 1st board | plate material 12 positioned correctly on the basis of the ruler surface 62, generation | occurrence | production of a defect can be suppressed and a production yield can be improved further. it can.

次に、テープ材28を使用して製造する場合について説明する。図3に示すように、両板材12、14の側面12a、14aを互いに当接させ、面一にした状態で、両板材12、14の表面に可撓性を有するテープ材28を貼り付け(図3(b))、前述同様に溝加工し(図3(c))、溝20に接着剤36を付着させた後(図3(d))、テープ材28をガイドにして折り曲げることによって両板材12、14を互いに固着させ、最後に当該テープ材28を剥がす(図3(e))。   Next, the case where it manufactures using the tape material 28 is demonstrated. As shown in FIG. 3, the tape material 28 which has flexibility is affixed on the surface of both board | plate materials 12 and 14 in the state which mutually contact | abutted the side surfaces 12a and 14a of both board | plate materials 12 and 14, and was flush | planar ( 3 (b)), the groove is processed in the same manner as described above (FIG. 3 (c)), and after the adhesive 36 is attached to the groove 20 (FIG. 3 (d)), the tape material 28 is bent as a guide. The two plate members 12 and 14 are fixed to each other, and finally the tape material 28 is peeled off (FIG. 3E).

なお、テープ材28を貼り付けるタイミングは、両板材12、14を互いに当接させた後、当接面22に形成された溝20を閉じるまでのいずれかの段階であればいつでもよい。また、上述した、第1および第2板材12、14の側面12a、14aにおける少なくとも一方の側面12aにテーパー面60を形成することを併用してもよい。   Note that the tape material 28 may be applied at any time from the time when the plate members 12 and 14 are brought into contact with each other until the groove 20 formed in the contact surface 22 is closed. Moreover, you may use together forming the taper surface 60 in the at least one side surface 12a in the side surfaces 12a and 14a of the 1st and 2nd board | plate materials 12 and 14 mentioned above.

テープ材28としては、貼着してから折り曲げ加工が完了するまでの間に両基材13、15あるいは表面材18から剥がれない程度の接着強度を有する一般的な薄型テープであれば、ビニル製や紙製等を問わずどのようなものでも使用することができるが、テープ材28の接着強度が強すぎると、当該テープ材28を剥がす際に表面材18まで剥がれてしまうことから、表面材18を使用する場合には接着強度が過度に強いテープ材を使用するべきでない点に注意を要する。したがって、貼った後に剥がすことを目的として使用されるものが好ましく、最も好適には、いわゆる養生テープが使用される。養生テープとは、建築等で仮固定に使用されるテープであり、一定期間貼着後には、剥がされることを目的としたテープである。そのため、養生テープののりが被着体に残りにくくなるよう設計されており、本製造方法に使用するには最も好適である。また、一般的な養生テープは、長さ方向に比べて横方向の切断強度を著しく弱くすることにより、長さ方向のカットが容易で、かつ幅方向に強度をもたせる配慮がなされていることから、本製造方法に使用した場合、板材同士の当接強度が確保できるとともに、貼り付け時に横方向のカットを容易に行うことができる。このような養生テープの製造方法は、例えば特開昭58−52380や特開平5−247421に開示されている。   The tape material 28 is made of vinyl as long as it is a general thin tape having an adhesive strength that does not peel off from both the base materials 13 and 15 or the surface material 18 between the time when the tape material is applied and the time when the bending process is completed. Any material can be used regardless of whether it is made of paper or paper. However, if the adhesive strength of the tape material 28 is too strong, the surface material 18 will be peeled off when the tape material 28 is peeled off. When using 18, it should be noted that a tape material with excessively strong adhesive strength should not be used. Therefore, what is used for the purpose of peeling after sticking is preferable, and a so-called curing tape is most preferably used. Curing tape is a tape used for temporary fixing in construction or the like, and is a tape intended to be peeled off after being stuck for a certain period. For this reason, the adhesive tape is designed to be less likely to remain on the adherend, and is most suitable for use in the present production method. In addition, the general curing tape is considered to be easy to cut in the length direction and have strength in the width direction by making the cutting strength in the transverse direction significantly weaker than that in the length direction. When used in this production method, the contact strength between the plate materials can be ensured, and the transverse cut can be easily performed at the time of attachment. Such a method for producing a curing tape is disclosed in, for example, JP-A-58-52380 and JP-A-5-247421.

このように、第1板材12から第2板材14にかけての表面に貼り付けた、可撓性を有するテープ材28を折り曲げることにより、両板材12、14の側面12a、14aの先端部が互いに当接した状態を維持しつつ接着固着させることができる。このとき、既に述べたようにテープ材28の折り曲げ部分で伸ばされた部分に発生した押圧力によって正確な先端密着が行われる。特に、V字状の溝20が表面に達して両板材12、14の先端が薄くなっている場合により効果的である。また、テープ材28は、溝20に付着させた接着剤36が表面にはみ出すのを防止する役割も有している。このように、テープ材28を用いることにより、両板材12、14の先端部同士が精度良く一致した見栄えのよい化粧材10を製造することができる。   In this way, by bending the flexible tape material 28 attached to the surface from the first plate material 12 to the second plate material 14, the end portions of the side surfaces 12a and 14a of the two plate materials 12 and 14 contact each other. It can be adhered and fixed while maintaining the contact state. At this time, as already described, accurate tip contact is performed by the pressing force generated at the portion of the tape material 28 that is bent at the bent portion. In particular, it is more effective when the V-shaped groove 20 reaches the surface and the tips of both plate members 12 and 14 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to the groove 20 from protruding to the surface. As described above, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the end portions of both the plate materials 12 and 14 are accurately matched.

また、図4に示すように、第1板材12の厚さと、第2板材14の厚さとが互いに異なるように設定してもよい。   Moreover, as shown in FIG. 4, you may set so that the thickness of the 1st board | plate material 12 and the thickness of the 2nd board | plate material 14 may mutually differ.

さらに、図5に示すように、互いに当接された第1板材12の表面と第2板材14の表面とが鈍角(90度より大きく、180度より小さい角度を意味する。さらに言えば、130度以上170度以下が好適である。図5には、約170度の場合を示している。)を成す状態で上述したテープ材28の貼り付けを行い(図5(b))、当該テープ材28を貼り付けた後、両板材12、14の当接角度がより大きくなるように広げてから、溝20を形成してもよい(図5(c))。   Furthermore, as shown in FIG. 5, the surface of the 1st board | plate material 12 and the surface of the 2nd board | plate material 14 which were contact | abutted mutually means an obtuse angle (an angle larger than 90 degree | times and smaller than 180 degree | times. The tape material 28 described above is applied in a state where the tape material 28 is formed (FIG. 5 (b)). After the material 28 is pasted, the groove 20 may be formed after spreading so that the contact angle between the two plate materials 12 and 14 becomes larger (FIG. 5C).

これにより、第1板材12の表面と第2板材14の表面とが鈍角を成す状態で両板材12、14の当該表面に貼り付けられたテープ材28には、両板材12、14の当接角度がより大きくなるように両板材12、14が広げられて(第1板材12の表面と第2板材14の表面との角度を180度にするのが好適である。)伸ばされたときに、縮もうとする力が生じる。この収縮力によって両板材12、14がより強く押し合わされるので、両板材12、14の先端部同士がさらに精度良く一致し、より見栄えの良い化粧材10を製造することができる。   As a result, the two plate members 12 and 14 come into contact with the tape member 28 attached to the surfaces of the two plate members 12 and 14 in a state where the surface of the first plate member 12 and the surface of the second plate member 14 form an obtuse angle. When both plate members 12 and 14 are expanded so that the angle becomes larger (preferably the angle between the surface of the first plate member 12 and the surface of the second plate member 14 is 180 degrees). The force to try to shrink arises. Since both the board | plate materials 12 and 14 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 14 correspond more accurately, and the cosmetics 10 with a more attractive appearance can be manufactured.

(第2実施例)
第2実施例について図6を用いて説明する。なお、上述した第1実施例と、この第2実施例とは、基本的に、両板材12、14を構成する両基材13、15のいずれか一方に木質繊維の基材が使用されていること、および形成される溝の数において相違しているだけであるから第2実施例の説明における第1実施例との共通部分については、第1実施例の説明を援用してその説明を省略し、相違部分を中心に説明する。
(Second embodiment)
A second embodiment will be described with reference to FIG. The first embodiment described above and the second embodiment basically use a wood fiber base material for either one of the base materials 13 and 15 constituting the both plate materials 12 and 14. And only the difference in the number of grooves to be formed will be described with reference to the description of the first embodiment for the common parts with the first embodiment in the description of the second embodiment. Omitted, the description will focus on the differences.

上述のように、本実施例の第1板材12および第2板材14を構成する第1基材13および第2基材15における少なくともいずれか一方には、木質繊維基材(中比重繊維板、高比重繊維板、MDFやHDF等の乾式成形木質繊維板、ハードボード等の湿式抄造木質繊維板等)が使用されている。以下、第1基材13が木質繊維基材である場合を例にして説明する。なお、第1板材12および第2板材14の表面柄(表面材18を使用しない場合は、第1基材13および第2基材15の表面柄、表面材18を使用する場合は、第1基材13に取り付けられる表面材18aおよび第2基材15に取り付けられる表面材18bの表面柄)が互いに異なるように設定されていることはいうまでもない。   As described above, at least one of the first base material 13 and the second base material 15 constituting the first plate material 12 and the second plate material 14 of the present embodiment has a wood fiber base material (medium specific gravity fiber plate, High specific gravity fiber boards, dry-molded wood fiber boards such as MDF and HDF, and wet paper-made wood fiber boards such as hard boards are used. Hereinafter, the case where the first base material 13 is a wood fiber base material will be described as an example. It should be noted that the surface handle of the first plate member 12 and the second plate member 14 (when the surface member 18 is not used, the surface handle of the first base member 13 and the second substrate 15 and the surface member 18 are used first. Needless to say, the surface material 18a attached to the base material 13 and the surface material 18b attached to the second base material 15 are set to be different from each other.

第1板材12および第2板材14の表面を面一とした状態で、第1板材12の側面12aと、これに対向する第2板材14の側面14aとを互いに当接させ、然る後、当接状態を維持しつつ、裏面から、両板材12、14の当接面22にその溝底部30aが一致した状態で、両板材12、14の表面あるいはその手前近傍に至るV字状の第1溝30を形成する。そして、第1溝30の形成と同時、あるいは第1溝30の形成に前後して、第1溝30に隣り合う別のV字状の第2溝32を第1板材12の木質繊維基材(=第1基材13)に形成する。   With the surfaces of the first plate member 12 and the second plate member 14 being flush with each other, the side surface 12a of the first plate member 12 and the side surface 14a of the second plate member 14 opposed thereto are brought into contact with each other. While maintaining the contact state, with the groove bottom 30a coinciding with the contact surfaces 22 of the two plate members 12 and 14, the V-shaped first ends extending from the rear surface to the front surfaces of the two plate members 12 and 14 or near the front thereof. One groove 30 is formed. At the same time as the formation of the first groove 30 or before and after the formation of the first groove 30, another V-shaped second groove 32 adjacent to the first groove 30 is provided as the wood fiber base material of the first plate 12. (= First substrate 13).

これにより、木質繊維基材(=第1基材13)の突き合わせ端部に直角三角形状の面取り部34が形成される。   As a result, a chamfered portion 34 having a right triangle shape is formed at the abutting end portion of the wood fiber base material (= first base material 13).

図示実施例では、第1溝30が、第1板材12と第2板材14との当接面22を境に、第1板材12側のみが切削加工された「片V字状の溝(本実施例では、第2板材14の裏面側角部が直角となった三角形)」として形成されており、第2溝32も同様に第2板材14との当接面22に向けて傾き、かつ、これと反対側角部が直角となった「片V字状の溝」が第1溝30と隣り合わせて対称に形成されている。加えて、本実施例の面取り部34は、その断面視において互いに直交する2つの辺34a、34bの長さが、それぞれ対応する第1および第2板材12、14における側面12a、14aの高さに一致するように形成されているので、折り曲げ加工を行ったとき、図6(e)に示すように、角部26の内側縁が直角になり、四角柱材の表面にぴったりと取り付けることのできる化粧材10を形成できる。(もちろん、図7に示すように、辺34a、34bの長さが側面12a、14aの高さよりも長くなるように形成してもよいし、逆に、短くしてもよい。)   In the illustrated embodiment, the first groove 30 is a “single V-shaped groove (the main groove) formed by cutting only the first plate 12 side with the contact surface 22 between the first plate 12 and the second plate 14 as a boundary. In the embodiment, the second plate member 14 is formed as a triangle having a right-angled corner on the back side, and the second groove 32 is similarly inclined toward the contact surface 22 with the second plate member 14, and In addition, a “single V-shaped groove” in which the corner on the opposite side is a right angle is formed symmetrically adjacent to the first groove 30. In addition, in the chamfered portion 34 of the present embodiment, the lengths of the two sides 34a and 34b that are orthogonal to each other in the sectional view correspond to the heights of the side surfaces 12a and 14a in the first and second plate members 12 and 14, respectively. As shown in FIG. 6 (e), when the bending process is performed, the inner edge of the corner portion 26 becomes a right angle, so that it can be attached to the surface of the quadrangular prism material. The possible decorative material 10 can be formed. (Of course, as shown in FIG. 7, the lengths of the sides 34a and 34b may be longer than the heights of the side surfaces 12a and 14a, or conversely, may be shortened.)

略三角形状の面取り部34を形成する際に溝加工を行う刃物からの応力を受けたとき、無垢木材、合板、あるいはパーティクルボード等の、「年輪や導管口の合わせ面」(無垢木材の場合)、「板材同士の合わせ面」(合板の場合)、あるいは「粒状物同士の合わせ面」(パーティクルボードの場合)といった「方向性を有する境目」から面取り部34の先端部等が飛び欠けてしまうおそれがあったが、本実施例に係る化粧材10の製造方法によれば、当該面取り部34は、木質繊維基材(=第1基材13)に形成されており、木質繊維基材は繊維が複雑に絡み合うようにして形成されており方向性が無い(無方向性)ことから、面取り部34の飛び欠けが生じるおそれを無くすることができる。   When receiving a stress from a cutting tool for grooving when forming a substantially triangular chamfered portion 34, “a mating surface of an annual ring or a conduit port” such as solid wood, plywood, or particle board (in the case of solid wood) ), “The mating surface between the plate materials” (in the case of plywood), or “the mating surface between the granular materials” (in the case of particle board), the tip portion of the chamfer 34 is skipped from the “directional boundary”. However, according to the manufacturing method of the decorative material 10 according to the present embodiment, the chamfered portion 34 is formed on the wood fiber base material (= first base material 13), and the wood fiber base material. Is formed so that the fibers are intertwined in a complicated manner and has no directionality (non-directionality), it is possible to eliminate the possibility that the chamfered portion 34 is skipped.

なお、上述した、溝加工の方法(両板材12、14を移動させるか、あるいは回転鋸を移動させるか)、溝底部30a、32aの位置を「各板材12、14の表面あるいはその手前近傍」とする理由、両溝30、32をそれぞれ一回の加工で「V字状の溝」に形成すること、接着剤36を両溝30、32の両表面あるいはいずれか一方の表面に付着させること、接着剤36を両基材13、15の表面の色(表面材18を取り付けない場合)や表面材18の表面の色(表面材18を取り付ける場合)と同色あるいは似た色に着色しておくこと、および、複数種類の接着剤36を併用することについて、本実施例にも適用できることはいうまでもない。   In addition, the above-described groove processing method (whether both plate members 12, 14 are moved or the rotary saw is moved), and the positions of the groove bottom portions 30a, 32a are "the surface of each plate member 12, 14 or the vicinity thereof" The reason is that both the grooves 30 and 32 are formed into “V-shaped grooves” by one processing, and the adhesive 36 is attached to both surfaces of the grooves 30 and 32 or one of the surfaces. The adhesive 36 is colored in the same color as or similar to the color of the surfaces of the base materials 13 and 15 (when the surface material 18 is not attached) and the surface color of the surface material 18 (when the surface material 18 is attached). Needless to say, the use of a plurality of types of adhesives 36 is also applicable to the present embodiment.

また、本実施例でも、既述のように、予めテーパー面60を形成して異物等の影響を受けにくくすることができるし、テープ材28を使用することもできる(さらに、第1板材12の表面と第2板材14の表面とが鈍角になるようにしてテープ材28を貼り付け、然る後、当該角度を広げて溝30、32を形成することもできる。)。テープ材28を使用する場合、第1溝30に対応する位置から第2溝32に対応する位置にかけて当該テープ材28を取り付けることになる。   Also in this embodiment, as described above, the tapered surface 60 can be formed in advance to make it less susceptible to the influence of foreign matter or the like, and the tape material 28 can be used (further, the first plate material 12). It is also possible to apply the tape material 28 so that the surface of the second plate 14 and the surface of the second plate member 14 have an obtuse angle, and then widen the angle to form the grooves 30 and 32. When the tape material 28 is used, the tape material 28 is attached from a position corresponding to the first groove 30 to a position corresponding to the second groove 32.

(第3実施例)
第3実施例について図7を用いて説明する。なお、上述した第1実施例と、この第3実施例とは、基本的に、第1、第2板材12、14に加えて、木質繊維基材が使用された第3板材50が使用されていること(第3板材50は、第3基材52だけの場合、あるいは、第3基材52の表面に接着剤層16を介して表面材18cが取り付けられている場合とがある。)、および当該第3板材50の両端に第1溝30および第2溝32が形成される点において相違しているだけであるから、第3実施例の説明における第1実施例との共通部分については、第1実施例の説明を援用してその説明を省略し、相違部分を中心に説明する。
(Third embodiment)
A third embodiment will be described with reference to FIG. The first embodiment described above and the third embodiment basically use a third plate member 50 using a wood fiber base material in addition to the first and second plate members 12 and 14. (The third plate member 50 may be the third base member 52 alone, or the surface member 18c may be attached to the surface of the third base member 52 via the adhesive layer 16). , And only the point that the first groove 30 and the second groove 32 are formed at both ends of the third plate member 50, and the common part with the first embodiment in the description of the third embodiment. The description of the first embodiment will be omitted with reference to the description of the first embodiment, and the differences will be mainly described.

第3基材52は、木質繊維基材で形成されている。木質繊維基材としては、木質繊維を接着剤で固めて板状あるいは角柱状(板状の木質繊維基材を切断加工したもの)等にした、中比重繊維板、高比重繊維板、MDFやHDF等の乾式成形木質繊維板、ハードボード等の湿式抄造木質繊維板等を使用することができる。   The third base material 52 is formed of a wood fiber base material. As the wood fiber base material, a medium specific gravity fiber board, a high specific gravity fiber board, MDF, etc., in which the wood fiber is solidified with an adhesive and made into a plate shape or a prismatic shape (a product obtained by cutting a plate-like wood fiber base material). It is possible to use a dry-formed wood fiber board such as HDF, or a wet paper-made wood fiber board such as a hard board.

また、第3板材50の表面柄(表面材18を使用しない場合は、第3基材52の表面柄、第3基材52の表面に表面材18cを使用する場合は、当該表面材18cの表面柄)は、第1板材12および第2板材14の表面柄と異なるように設定される。例えば、各板材12、14、50の表面柄をそれぞれ順に板目模様、柾目模様、面取り部の模様にすることにより、本物の質感を有する框材を製造することができる。   Further, the surface pattern of the third plate material 50 (if the surface material 18 is not used, the surface pattern of the third base material 52, and if the surface material 18c is used on the surface of the third base material 52, the surface material 18c The surface pattern) is set to be different from the surface patterns of the first plate member 12 and the second plate member 14. For example, by making the surface pattern of each of the plate members 12, 14, and 50 into a plate pattern, a checkered pattern, and a chamfered pattern in order, it is possible to manufacture a checkered material having a real texture.

次に、第1板材12、第2板材14、および第3板材50を用いて、完成品である「表面材18を有する化粧材10」を中心に、表面材18を用いない場合も含めて、テープ材28を用いることなく製造する手順について説明する。   Next, using the first plate member 12, the second plate member 14, and the third plate member 50, including the case where the surface material 18 is not used, centering on the “decorative material 10 having the surface material 18” as a finished product. A procedure for manufacturing without using the tape material 28 will be described.

まず、接着剤層16を介して表面材18が設けられた第1板材12、第2板材14、および第3板材50を用意し(図7(a))、各板材12、14、50の表面を面一とした状態で第3板材50を第1板材12と第2板材14との間に配置し、然る後、第3板材50の両側面50a、50bに、第1板材12の側面12aおよび第2板材14の側面14aをそれぞれ突き合わせて当接させる(図7(b))。   First, the 1st board | plate material 12, the 2nd board | plate material 14, and the 3rd board | plate material 50 in which the surface material 18 was provided through the adhesive bond layer 16 were prepared (FIG.7 (a)), and each board | plate material 12,14,50 of The third plate member 50 is disposed between the first plate member 12 and the second plate member 14 with the surface being flush, and then the both sides 50a, 50b of the third plate member 50 are placed on the first plate member 12. The side surface 12a and the side surface 14a of the second plate member 14 are abutted and brought into contact with each other (FIG. 7B).

各板材12、14、50を当接させた後、その当接状態を維持しつつ、各板材12、14、50の裏面に現れている当接面22、23に図示しないV字状の回転鋸の刃先を合致させた後、回転鋸で切除して、回転鋸の形状に合致したV字状の第1および第2溝30、32を形成する(図7(c))。V字状の第2溝32は、第1溝30と同時あるいは第1溝30に前後して、当該第1溝30に隣接するように形成される。第1および第2溝30、32が形成された第3板材50は正面視三角形(本実施例では直角二等辺三角形)に形成される。   After the plate members 12, 14, and 50 are brought into contact with each other, the V-shaped rotation (not shown) is applied to the contact surfaces 22 and 23 appearing on the back surfaces of the plate members 12, 14, and 50 while maintaining the contact state. After matching the cutting edge of the saw, it is cut out by a rotary saw to form V-shaped first and second grooves 30 and 32 that match the shape of the rotary saw (FIG. 7C). The V-shaped second groove 32 is formed adjacent to the first groove 30 at the same time as the first groove 30 or before and after the first groove 30. The 3rd board | plate material 50 in which the 1st and 2nd groove | channels 30 and 32 were formed is formed in a front view triangle (this example right-angled isosceles triangle).

第1および第2溝30、32は、その溝底部30a、32aが、当接面22、23に一致しており、かつ、各板材12、14、50を構成する各基材13、15、52の表面あるいはその手前近傍に至るように(従って、この場合は表面材18の裏面は切削されない。)、または各基材13、15、52を越えて表面材18の表面(すなわち、各板材12、14、50の表面)あるいはその手前近傍に至るように少なくとも第3板材50に形成される(従って、この場合は少なくとも第3板材50の表面材18の突合せ端部が切削されて薄くなっている。)。   The first and second grooves 30, 32 have groove bottom portions 30 a, 32 a that coincide with the contact surfaces 22, 23, and each base material 13, 15, 15 constituting each plate member 12, 14, 50. 52 (or in this case, the back surface of the surface material 18 is not cut), or the surface of the surface material 18 beyond each base material 13, 15, 52 (that is, each plate material). 12, 14, and 50) or at least near the front side thereof (that is, in this case, at least the butt end portion of the surface material 18 of the third plate 50 is cut and thinned). ing.).

図示実施例では、第1および第2溝30、32が、当接面22、23を境として第3板材50側のみを切削加工して形成された、「片V字状の溝(本実施例では第1および第2板材12、14の裏面側角部が直角となった三角形)」として、互いに対称にかつ隣り合わせて形成されている。これにより、前述のように木質繊維基材(=第3基材52)が直角三角形状の面取り部34に形成される。もちろん、各溝30、32を、第3板材50側のみならず第1板材12や第2板材14側にかかるように切削加工された、「V字状の溝」に形成してもよい。切削された第1および第2溝30、32は回転鋸の形状に合致した形状に切削される。   In the illustrated embodiment, the first and second grooves 30 and 32 are formed by cutting only the third plate member 50 side with the contact surfaces 22 and 23 as a boundary. In the example, the first and second plate members 12 and 14 are formed so as to be symmetrical and adjacent to each other as “a triangle in which the corners on the back surface side become right angles”. Thereby, a wood fiber base material (= 3rd base material 52) is formed in the chamfer 34 of a right triangle shape as mentioned above. Of course, each of the grooves 30 and 32 may be formed as a “V-shaped groove” that is cut not only on the third plate member 50 side but also on the first plate member 12 and the second plate member 14 side. The cut first and second grooves 30 and 32 are cut into a shape that matches the shape of the rotary saw.

なお、幅方向により長い第3板材50を使用して第1溝30から離れた位置に第2溝32を形成してもよく、この場合、角部26から角部27に至る面取り長さが図示したものよりも長くなる。また、第2溝32を第1溝30から離れた位置に形成し、かつ、第1溝30を第2板材14側も切削加工した「V字状の溝」として形成し、第2溝32も同様に「V字状の溝」として形成することにより、図8に示すように、「コ字状の化粧材10」を製造することができる。この場合も、各板材12、14、50の表面柄、材質、厚さが異なる化粧材10を製造することができる。   In addition, you may form the 2nd groove | channel 32 in the position away from the 1st groove | channel 30 using the 3rd board | plate material 50 longer in the width direction, and the chamfering length from the corner | angular part 26 to the corner | angular part 27 is sufficient in this case. It will be longer than what is shown. Further, the second groove 32 is formed at a position away from the first groove 30, and the first groove 30 is formed as a “V-shaped groove” in which the second plate 14 side is also cut, and the second groove 32. Are formed as “V-shaped grooves” in the same manner, as shown in FIG. 8, a “U-shaped decorative material 10” can be manufactured. Also in this case, the decorative material 10 in which the surface patterns, materials, and thicknesses of the plate members 12, 14, and 50 are different can be manufactured.

各板材12、14、50を当接させた状態のまま(この段階においては、図示するように、表面材18を用いない場合には各板材12、14、50の表面側端部、または、表面材18を用いる場合には表面材18同士が当接した状態になっている。)、両溝30、32の表面にホットメルト系接着剤、PURホットメルト系接着剤、水性ビニルウレタン系接着剤、酢ビ系接着剤、あるいはウレタン系接着剤等の接着剤36を付着させ(図7(d))、然る後、両溝30、32を閉じて各板材12、14、50を互いに固着させることにより、化粧材10が完成する(図7(e))。   While the plate members 12, 14, and 50 are kept in contact with each other (at this stage, as shown in the figure, when the surface member 18 is not used, the surface side ends of the plate members 12, 14, and 50, or When the surface material 18 is used, the surface materials 18 are in contact with each other.), A hot melt adhesive, a PUR hot melt adhesive, and an aqueous vinyl urethane adhesive are attached to the surfaces of the grooves 30 and 32. Adhesive 36 such as an adhesive, vinyl acetate adhesive, or urethane adhesive is attached (FIG. 7 (d)), and then both grooves 30, 32 are closed to connect the plate members 12, 14, 50 to each other. By fixing, the decorative material 10 is completed (FIG. 7E).

第1ないし第3板材12、14、50は、既に述べたように別個の部材であるから、互いの表面柄や材質(硬さや板厚等)が異なる第1ないし第3板材12、14、50を用いて化粧材10を製造することが可能となる。このため、例えば、各板材12、14、50の表面柄をそれぞれ順に板目模様、柾目模様、面取り部の模様にすることにより、本物の質感を有する框材を製造することができる。   Since the 1st thru | or 3rd board | plate materials 12,14,50 are separate members as already stated, the 1st thru | or 3rd board | plate materials 12,14 from which each surface pattern and material (hardness, board thickness, etc.) differ. 50 can be used to manufacture the decorative material 10. For this reason, for example, by making the surface pattern of each of the plate members 12, 14, and 50 into a plate pattern, a checkered pattern, and a chamfered pattern in order, it is possible to manufacture a checkered material having a real texture.

また、木質繊維基材(=第3基材52)に面取り部34を成形した場合、木質繊維基材は繊維が複雑に絡み合うようにして形成されており方向性が無い(無方向性)ことから、面取り部34の飛び欠けが生じるおそれを無くすることができる。   Further, when the chamfered portion 34 is formed on the wood fiber base material (= the third base material 52), the wood fiber base material is formed so that the fibers are intertwined in a complicated manner and has no directionality (non-directional). Therefore, it is possible to eliminate the possibility that the chamfered portion 34 skips.

なお、上述した、溝加工の方法(各板材12、14、50を移動させるか、あるいは回転鋸を移動させるか)、溝底部30a、32aの位置を「各板材12、14、50の表面あるいはその手前近傍」とする理由、両溝30、32をそれぞれ一回の加工で「V字状の溝」に形成すること、接着剤36を両溝30、32の両表面あるいはいずれか一方の表面に付着させること、接着剤36を各基材13、15、52の表面の色(表面材18を取り付けない場合)や表面材18の表面の色(表面材18を取り付ける場合)と同色あるいは似た色に着色しておくこと、および、複数種類の接着剤36を併用することについて、本実施例にも適用できることはいうまでもない。   The groove processing method (whether the plate members 12, 14, 50 are moved or the rotary saw is moved), and the position of the groove bottom portions 30a, 32a are defined as "the surface of each plate member 12, 14, 50 or The reason that it is “near the front”, both grooves 30 and 32 are formed into “V-shaped grooves” by one processing, and the adhesive 36 is formed on both surfaces of either of the grooves 30 and 32 or on either surface thereof. The adhesive 36 is the same color as or similar to the color of the surface of each of the base materials 13, 15, 52 (when the surface material 18 is not attached) Needless to say, the present invention can be applied to the present embodiment with respect to coloring in different colors and using a plurality of types of adhesives 36 in combination.

また、図10に示すように、第3板材50に第1および第2板材12、14を当接させる前段階において、第3板材50の両側面50a、50b、第1板材12の第3板材50に当接する側面12a、および第2板材14の第3板材50に当接する側面14aの少なくともいずれか一面に、当該面を有する板材12、14、50の表面と鋭角を成すテーパー面60を形成してもよい(図10では、第3板材50の両側面50a、50bにテーパー面60が形成されている。)。なお、第3板材50の表面とテーパー面60とが成す鋭角は、当該第3板材50の表面と、後に形成されるV字状の溝30あるいは32による面とが成す角度(鋭角)よりも大きい。   In addition, as shown in FIG. 10, before the first and second plate members 12 and 14 are brought into contact with the third plate member 50, both side surfaces 50 a and 50 b of the third plate member 50 and the third plate member of the first plate member 12. A tapered surface 60 that forms an acute angle with the surfaces of the plate members 12, 14, 50 having the surface is formed on at least one of the side surface 12a that contacts the plate 50 and the side surface 14a that contacts the third plate member 50 of the second plate member 14. (In FIG. 10, tapered surfaces 60 are formed on both side surfaces 50a and 50b of the third plate member 50). The acute angle formed by the surface of the third plate member 50 and the tapered surface 60 is greater than the angle (acute angle) formed by the surface of the third plate member 50 and the surface formed by the V-shaped groove 30 or 32 formed later. large.

これにより、第3板材50の側面50aと、第1板材12の側面12aおよび第2板材14の側面14aとの間に異物等が存在しても、各板材12、14、50同士を互いに当接させる際に当該異物等を逃がすことにより、各板材12、14、50の表面同士を正確に当接させることができ、不良の発生を抑えて生産歩留まりを飛躍的に向上させることができる。   As a result, even if foreign matter or the like exists between the side surface 50a of the third plate member 50, the side surface 12a of the first plate member 12, and the side surface 14a of the second plate member 14, the plate members 12, 14, 50 are brought into contact with each other. By letting out the foreign matters when contacting, the surfaces of the plate members 12, 14, 50 can be brought into contact with each other accurately, and the production yield can be dramatically improved by suppressing the occurrence of defects.

また、同じく図10に示すように、第1板材12における、第3板材50に当接される側面12aに対向する反対側の側面12bを定規面62に形成しておき、当該第1板材12に第3板材50、さらに第2板材14を当接させる際に、当該定規面62を基準として位置決めした第1板材12の側面12aに、テーパー面60が形成された第3板材50の側面50aを押し当ててもよい。   Similarly, as shown in FIG. 10, a side surface 12 b opposite to the side surface 12 a in contact with the third plate material 50 in the first plate material 12 is formed on the ruler surface 62, and the first plate material 12. When the third plate member 50 and the second plate member 14 are brought into contact with each other, the side surface 50a of the third plate member 50 in which the tapered surface 60 is formed on the side surface 12a of the first plate member 12 positioned with reference to the ruler surface 62. May be pressed.

これにより、定規面62を基準として正確に位置決めされた第1板材12に対して第3板材50および第2板材14を正確に当接させることができるので、不良の発生を抑えて生産歩留まりをさらに向上させることができる。   Thereby, since the 3rd board | plate material 50 and the 2nd board | plate material 14 can be correctly contact | abutted with respect to the 1st board | plate material 12 correctly positioned on the basis of the ruler surface 62, generation | occurrence | production of a defect can be suppressed and a production yield can be suppressed. Further improvement can be achieved.

次にテープ材28を使用して製造する場合について説明する。図9に示すように、各板材12、14、50の側面12a、14a、50aを互いに当接させ、面一にした状態で、第3板材50を中心に各板材12、14、50の表面に可撓性を有するテープ材28を貼り付け(図9(b))、前述同様に溝加工し(図9(c))、両溝30、32に接着剤36を付着させた後(図9(d))、テープ材28をガイドにして折り曲げることによって各板材12、14、50を互いに固着させ、最後に当該テープ材28を剥がす(図9(e))。   Next, the case where it manufactures using the tape material 28 is demonstrated. As shown in FIG. 9, the surfaces of the plate members 12, 14, 50 around the third plate member 50 in a state where the side surfaces 12 a, 14 a, 50 a of the plate members 12, 14, 50 are in contact with each other and are flush with each other. A flexible tape material 28 is affixed to the groove 30 (FIG. 9B), grooves are processed in the same manner as described above (FIG. 9C), and the adhesive 36 is attached to both grooves 30, 32 (FIG. 9). 9 (d)), the plate members 12, 14, 50 are fixed to each other by being bent with the tape member 28 as a guide, and finally the tape member 28 is peeled off (FIG. 9 (e)).

なお、テープ材28を貼り付けるタイミングは、各板材12、14、50を互いに当接させた後、当接面22、23に形成された両溝30、32を閉じるまでのいずれかの段階であればいつでもよい。また、テープ材28は、図示するように第1板材12から第3板材50を越えて第2板材14まで貼り付けてもよいし、第1板材12と第3板材50との間、および第2板材14と第3板材50との間に分けて貼り付けてもよい。既述のように、第1溝30から離れた位置に第2溝32を形成した場合も同様である。   The timing of attaching the tape material 28 is at any stage from when the plate members 12, 14, 50 are brought into contact with each other until the grooves 30, 32 formed on the contact surfaces 22, 23 are closed. Anytime if you want. Further, as shown in the figure, the tape material 28 may be pasted from the first plate material 12 to the second plate material 14 beyond the third plate material 50, or between the first plate material 12 and the third plate material 50, and the second plate material 50. The two plate members 14 and the third plate member 50 may be attached separately. As described above, the same applies when the second groove 32 is formed at a position away from the first groove 30.

このように第1板材12から第3板材50を挟んで第2板材14にかけての表面に貼り付けた可撓性を有するテープ材28を折り曲げることにより、第1および第2板材12、14の側面12a、14aの先端部と第3板材50の薄い先端部とが互いに当接した状態を維持しつつ接着固着させることができる。このとき、既に述べたようにテープ材28の折り曲げ部分で伸ばされた部分に発生した押圧力によって正確な先端密着が行われる。特に、V字状の両溝30、32が表面に達して各板材12、14、50の先端が薄くなっている場合により効果的である。また、テープ材28は、両溝30、32に付着させた接着剤36が表面にはみ出すのを防止する役割も有している。このように、テープ材28を用いることにより、各板材12、14、50の先端部同士が精度良く一致した見栄えのよい化粧材10を製造することができる。   The side surfaces of the first and second plate members 12 and 14 are thus bent by bending the flexible tape member 28 attached to the surface of the second plate member 14 with the first plate member 12 and the third plate member 50 interposed therebetween. The tips of 12a and 14a and the thin tip of the third plate member 50 can be adhered and fixed while maintaining a state where they are in contact with each other. At this time, as already described, accurate tip contact is performed by the pressing force generated at the portion of the tape material 28 that is bent at the bent portion. In particular, it is more effective when the V-shaped grooves 30, 32 reach the surface and the tips of the plate members 12, 14, 50 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to both grooves 30 and 32 from protruding to the surface. Thus, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the tip portions of the plate materials 12, 14, and 50 are accurately matched.

また、図10に示すように、互いに当接された第1板材12の表面と第3板材50の表面とが鈍角(90度より大きく、180度より小さい角度を意味する。さらに言えば、130度以上170度以下が好適である。図10には、約170度の場合を示している。)を成す状態で上述したテープ材28の貼り付けを行い(図10(b))、当該テープ材28を貼り付けた後、両板材12、50の当接角度がより大きくなるように広げてから、溝30、32を形成してもよい(図10(c))。本実施例では、第1板材12と第3板材50とが鈍角で当接されているが、もちろん、第2板材14と第3板材50とを鈍角で当接させてもよいし、第1板材12および第2板材14の両方を第3板材50に鈍角で当接させてもよい。   As shown in FIG. 10, the surface of the first plate 12 and the surface of the third plate 50 that are in contact with each other means an obtuse angle (an angle greater than 90 degrees and less than 180 degrees. The tape material 28 described above is applied in a state where the tape material 28 is formed (FIG. 10 (b)). After affixing the material 28, the grooves 30 and 32 may be formed after spreading so that the contact angle between the two plate materials 12 and 50 becomes larger (FIG. 10C). In the present embodiment, the first plate member 12 and the third plate member 50 are in contact with each other at an obtuse angle, but of course, the second plate member 14 and the third plate member 50 may be in contact with each other at an obtuse angle. Both the plate member 12 and the second plate member 14 may be brought into contact with the third plate member 50 at an obtuse angle.

これにより、第1板材12の表面と第3板材50の表面とが鈍角を成す状態で両板材12、50の当該表面に貼り付けられたテープ材28には、両板材12、50の当接角度がより大きくなるように両板材12、50が広げられて(第1板材12の表面と第3板材50の表面との角度を180度にするのが好適である。)伸ばされたときに、縮もうとする力が生じる。この収縮力によって両板材12、50がより強く押し合わされるので、両板材12、50の先端部同士がさらに精度良く一致し、より見栄えの良い化粧材10を製造することができる。   As a result, the two plate members 12, 50 are brought into contact with the tape member 28 attached to the surfaces of the two plate members 12, 50 in a state where the surface of the first plate member 12 and the surface of the third plate member 50 form an obtuse angle. When both plate members 12, 50 are expanded so that the angle becomes larger (preferably, the angle between the surface of the first plate member 12 and the surface of the third plate member 50 is 180 degrees). The force to try to shrink arises. Since both the board | plate materials 12 and 50 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 50 match more accurately, and the cosmetic material 10 with a more attractive appearance can be manufactured.

また、上記第1〜第3実施例のすべてに言えることであるが、一般的な印刷シートは、輪転機印刷された、数千〜数万m単位の印刷ロットを必要とする。壁材や床材等の大面積を施工する製品に利用する場合であれば、このように印刷ロットが大きくても問題ないが、框、踏板、幅木等のように施工面積の小さな化粧材に印刷シートを使用する場合、印刷ロットが大きいものについては、多種類の表面柄を準備しておくことができず、選択の自由度がなかった。とりわけ、面取り部34に使用する絵柄は使用量が少ないことから、上述した印刷ロットの問題が顕著であった。   In addition, as can be said for all of the first to third embodiments, a general printing sheet requires a printing lot printed on a rotary press in units of thousands to tens of thousands of meters. If it is used for products with large areas such as wall materials and flooring, there is no problem even if the printing lot is large in this way, but cosmetics with a small construction area such as fences, treads, baseboards, etc. In the case of using a printing sheet for a large number of printing lots, it was not possible to prepare many kinds of surface patterns and there was no freedom of selection. In particular, since the pattern used for the chamfered portion 34 has a small amount of use, the above-mentioned problem of the printing lot is remarkable.

そのため、各基材13、15、52の表面に、表面材18a、18b、18cとして予めインク受容層を有する紙を取り付けておき、当該紙の表面にインクジェット印刷によって所望の表面柄を形成しておくことが好ましい。インクジェット印刷を用いて、より小面積(例えば3尺×6尺板単位)で表面材18a、18b,18cの化粧柄を印刷でき、多種類の表面柄を準備しても在庫リスクが少なく、自由度の大きな製品設計が可能になるからである。   Therefore, a paper having an ink receiving layer is attached in advance as the surface material 18a, 18b, 18c to the surface of each base material 13, 15, 52, and a desired surface pattern is formed on the surface of the paper by ink jet printing. It is preferable to keep. By using inkjet printing, the decorative pattern of the surface material 18a, 18b, 18c can be printed in a smaller area (for example, 3 × 6 plate unit), and even if a variety of surface patterns are prepared, inventory risk is low and free This is because a large degree of product design becomes possible.

加えて、予め化粧柄が形成された表面材18a、18b,18cを両基材13、15,52に貼着する場合、当該表面材18a、18b,18cを貼着する接着剤が固化するまでの間の養生を必要とするため、生産性がどうしてもあがらないという問題があるが、上述のように、インク受容層を有する紙を予め各基材13、15、52の表面に貼着一体化しておき、必要に応じて印刷を行うことにより、上述したような養生期間が不要となり、短納期で化粧材を生産することが可能となる。   In addition, when the surface materials 18a, 18b, and 18c on which the decorative pattern has been formed are pasted on the base materials 13, 15, and 52, until the adhesive that pastes the surface materials 18a, 18b, and 18c is solidified. However, as described above, the paper having the ink receiving layer is stuck and integrated on the surfaces of the base materials 13, 15, and 52 in advance. In addition, by performing printing as necessary, the curing period as described above becomes unnecessary, and it becomes possible to produce a cosmetic material with a short delivery time.

なお、インクジェット印刷は、一般的な厚板に対する印刷が可能な設備を利用すればよく、耐水性に優れたUV着色インクを利用するのが好ましい。   Ink jet printing may be performed using a facility capable of printing on a general thick plate, and it is preferable to use UV colored ink having excellent water resistance.

また、インクジェット印刷後、直ちにインクジェット印刷の表面に透明塗料を塗布しておく(下塗り)ことにより、後工程で、テープを貼ったり、溝加工するときの搬送等による傷つきを防ぐことができる。   In addition, by applying a transparent paint to the surface of ink jet printing immediately after ink jet printing (undercoating), it is possible to prevent damage due to transport or the like when a tape is applied or grooves are processed in a subsequent process.

このような透明塗料としては、一般的なアクリル系、ウレタン系等の化粧材用塗料が使用されるが、ホワイトアルミナ、グリーンカーボン等のいわゆる減摩剤を含む下塗り塗料を使用するのが好ましい。もちろん、下塗りした透明塗料の表面にさらに透明塗料を塗布することにより(上塗り)、搬送時等に生じてしまった傷を消すようにしてもよい。   As such a transparent paint, a general paint for acrylic, urethane or the like is used, but an undercoat containing a so-called antifriction agent such as white alumina or green carbon is preferably used. Needless to say, the surface of the undercoated transparent coating may be further coated with a transparent coating (overcoating) so as to erase the scratches generated during transportation.
