Description

【０００１】
【発明の属する技術分野】
本発明は、基材の平面部から側面部にかけて熱硬化性樹脂化粧板が曲面状に一連に被覆された積層板、及び、その製造方法に関する。詳しくは、熱硬化性樹脂化粧板の折り曲げ曲率半径を極めて小さくすることのできる積層板及びその製造方法に関する。
【０００２】
【従来の技術】
基材と、この基材の平面部、及び、側端部に一連に被覆された熱硬化性樹脂化粧板と、からなる積層板は、表面が硬くて傷がつきにくく、耐熱性にも優れ、さらには、意匠性にも富むため、各種カウンターや、キッチンの扉等に広く用いられている。
【０００３】
図８にこの積層板の一例を示す。なお、ここでは、積層板の板端部の部分断面図を示す。この積層板２０は、例えば、合板からなる平板状の基材２１を用意し、この基材２１の角部を曲面加工して曲面部２４を設ける。次いで、メラミン樹脂化粧板等からなる熱硬化性樹脂化粧板２３を用意し、この熱硬化性樹脂化粧板２３を、基材２１の平面部、曲面部２４、及び、側端部２２に沿って接着する。この際、曲面部２４への接着は、熱硬化性樹脂化粧板２３を加熱し、外力によって曲げながら行う。熱硬化性樹脂化粧板を用いたこのような加工は、一般にポストフォーム加工と呼ばれている。
【０００４】
ところで、この積層板２０においては、曲面部２４の曲率半径は、最小で１０ｍｍ程度である。なぜならば、熱硬化性樹脂化粧板２３は柔軟性がないため、曲面部２４の曲率半径が１０ｍｍ程度より小さいと、積層板２０の製造時において、熱硬化性樹脂化粧板２３を曲げられなかったり、あるいは、無理に曲げて熱硬化性樹脂化粧板２３を破損したりするからである。
【０００５】
一方、この積層板２０の曲面部２４において、より優れた外観的意匠性を求める要望がある。これは、曲面部２４の曲率半径をできる限り小さく、具体的には、曲率半径が５ｍｍ程度以下の積層板２０を得たいというものである。すなわち、曲面部２４の曲率半径が小さいほど、例えば２〜３ｍｍ程度であると、曲面部２４は外部から直線状になって見え、外観形状としてシャープな印象を与えるので、用途によっては、このようなものが使用者に好まれる場合がある。
【０００６】
ところで、特許文献１には、基材に化粧材を貼着した後、化粧材裏面側の基材を切削して湾曲面形成部を形成するとともに、基材に切欠きを形成し、湾曲面形成部を切削後の基材に貼着することにより、折り曲げ部の曲率半径を５ｍｍ以下にすることができる、という技術が開示されている。
【０００７】
しかしながら、特許文献１の技術は、化粧材として、印刷紙、つき板、布、合成樹脂シート等、厚みが極めて薄く、かつ、容易に曲げることができる材料を前提としている。ゆえに、上記積層板２０のように、化粧材として熱硬化性樹脂化粧板を使用する場合は、この技術を適用することは難しい。

【発明が解決しようとする課題】
ゆえに、本発明が解決しようとする課題は、基材の平面部から側面部にかけて熱硬化性樹脂化粧板が曲面状に一連に被覆された積層板において、熱硬化性樹脂化粧板の折り曲げ曲率半径を極めて小さくすることのできる積層板、及び、その製造方法を提供することである。
【００１０】
【課題を解決する手段】
上記の課題を解決するためになされた請求項１の発明は、角部に面取り状切欠き部が設けられた基材と、上記面取り状切欠き部に対応する個所に薄肉部が設けられた熱硬化性樹脂化粧板と、からなる積層板であって、上記熱硬化性樹脂化粧板は上記薄肉部において曲げられて、上記面取り状切欠き部が被覆されていることを特徴とする積層板である。この面取り状切欠き部とは、基材の角部に設けられた切欠きであって、角部に面取りを施すことにより形成されるものである。
【００１１】
すなわち、この積層板は、熱硬化性樹脂化粧板に薄肉部が設けられており、熱硬化性樹脂化粧板は、薄肉部において厚みが薄くなって柔軟になるため、熱硬化性樹脂化粧板は、この薄肉部において、容易に曲げることができるようになる。
【００１２】
また、熱硬化性樹脂化粧板は、薄肉部において、面取り状切欠き部に沿って、この面取り状切欠き部を被覆するので、この個所における熱硬化性樹脂化粧板の曲げは、基材に対して出っ張ったりすることなく、面取り状切欠き部の形状に沿った自然な曲面となる。ゆえに、この積層板は、熱硬化性樹脂化粧板の折り曲げ曲率半径が極めて小さくなり、外部からは、直線状となって見えるようになる。
【００１３】
ここで、熱硬化性樹脂化粧板の曲げは、面取り状切欠き部、及び、薄肉部により囲まれる空隙部にホットメルト性接着剤を充填するとともに、薄肉部の外側から加熱しながら行うとよい。熱硬化性樹脂化粧板を加熱することにより可塑性が増大して曲げやすくなるとともに、加熱によってホットメルト性接着剤が融解し、空隙部における基材と熱硬化性樹脂化粧板との接着が確実に行われる。
【００１４】
請求項２の発明は、請求項１の積層板の製造方法であって、前記面取り状切欠き部、及び、前記薄肉部を形成する工程は、切欠き切削面、及び、薄肉部切削面を有するカッターにより同時に形成する工程であることを特徴とする積層板の製造方法である。
【００１５】
請求項１の積層板においては、面取り状切欠き部、及び、薄肉部はそれぞれ接する個所にて形成されているので、この製造方法は、切欠き切削面、及び、薄肉部切削面を有するカッターで、面取り状切欠き部、及び、薄肉部を同時に形成するものである。
【００１６】
請求項３の発明は、前記カッターが、前記基材に対する切削深さが可変であることを特徴とする請求項２の積層板の製造方法である。
【００１７】
この積層板における熱硬化性樹脂化粧板の折り曲げ加工は、薄肉部を折り曲げて、面取り状切欠き部を被覆するものであるので、この際の曲げ部の曲率半径は、この面取り状切欠き部の大きさによることとなる。ここで、基材に対するカッターの切削深さを変化させれば、任意の大きさの面取り状切欠き部が得られるので、切削深さを可変とし、切削深さを適選調整すれば、単一のカッターにより、任意の大きさの折り曲げ曲率半径である積層板が得られることとなる。
【００１８】
【発明の実施の形態】
以下に、本発明の実施の形態を、図面を参照して説明する。図１は、本発明にかかる積層板７の板端部分の断面図である。この積層板７は、基材１と、熱硬化性樹脂化粧板３と、からなる。詳しくは、基材１の角部には面取り状切欠き部１１が形成され、熱硬化性樹脂化粧板３の、面取り状切欠き２４に対応する個所には薄肉部５が設けられている。熱硬化性樹脂化粧板３は、基材１の平面部、面取り状切欠き部１１、及び、側端部に接着されて、基材１を一連に被覆している。特に、熱硬化性樹脂化粧板３は、薄肉部５が曲げられて、面取り状切欠き部１１に沿って被覆されている。さらには、面取り状切欠き２４と、薄肉部５によって囲まれる空隙部には、ホットメルト性接着剤６が充填されている。
【００１９】
次に、この積層板７の製造方法を示す。まず、図２に示すように、基材１、及び、熱硬化性樹脂化粧板３を用意する。基材１の材料としては、切削の容易な木質材料、例えば、木質単板、木質合板、中質繊維板（ＭＤＦ）、パーティクルボード等を用い、形状は、積層板の用途に応じ適宜選択する。また、熱硬化性樹脂化粧板３の樹脂の種類としては、メラミン、ダップ、ポリエステル等があり、これも積層板の用途に応じて適宣選択する。そして、基材１の平面部に、熱硬化性樹脂化粧板３を、側端部に接着される巻き込み部２を残し、接着する。
【００２０】
次いで、図３に示すように、基材１の角部に面取り状切欠き部１１を設ける。さらに、熱硬化性樹脂化粧板３の、面取り状切欠き２４に対応する個所に薄肉部５を設ける。
【００２１】
続いて、図４に示すように、面取り状切欠き部１１、及び、薄肉部５により囲まれる空隙部にホットメルト性接着剤６を充填し、薄肉部５をヒーター４で加熱しながら熱硬化性樹脂化粧板３を折り曲げ、巻き込み部２の裏面側を基材１の側面部に接着する。
【００２２】
熱硬化性樹脂化粧板３は、加熱することにより薄肉部５の可塑性が増し、極めて容易に曲げることができるようになる。従って、このような曲げ加工を行うことで、熱硬化性樹脂化粧板３の折り曲げ部の曲率半径は、２〜３ｍｍ程度の極めて小さなものが得られる。
【００２３】
ここで、図４に示す面取り状切欠き部１１、及び、薄肉部５は、図５に示すカッター８を用いて、同時に形成するとよい。図６は、この加工で用いるカッター８の先端部の部分断面図である。このカッター８は、切欠き切削面９、及び、薄肉部切削面１０を有する。実際の加工においては、このカッター８を複数個円状に連なって構成した回転カッターを用意し、この回転カッターを回転させて、図５に示すような切削加工を行う。
【００２４】
また、熱硬化性樹脂化粧板３の曲げ加工においては、薄肉部５を面取り状切欠き部１１に沿うように曲げながら被覆するので、熱硬化性樹脂化粧板３の折り曲げ曲率半径は、面取り状切欠き部１１の大きさによることとなる。
【００２５】
図５からわかるように、この面取り状切欠き部１１の大きさは、基材１に対するカッター８の切削深さで決定される。ゆえに、このカッター８の切削深さを調整すれば、加工において、面取り状切欠き部１１の大きさを変化させることができる。従って、製造時にカッター８の切削深さを調整すれば、同一材料で熱硬化性樹脂化粧板３の折り曲げ曲率半径が異なる積層板を得ることができることとなる。
【００２６】
次に、本発明の実施例を説明する。
【実施例１】積層板７の材料として合板からなる基材１、及び、厚みが０．８ｍｍのメラミン樹脂化粧板からなる熱硬化性樹脂化粧板３を用意した。また、先端部の断面寸法が図７に示す形状であるカッター８を１０個用い、これを円状に構成した回転カッターを用意した。
【００２７】
基材１の平面部に熱硬化性樹脂化粧板３をゴム系接着剤で接着した後、切削深さが３ｍｍ、熱硬化性樹脂化粧板３の薄肉部５の厚みが０．４ｍｍになるようにカッター８の位置を調整して、切削加工を行い、面取り状切欠き部１１、及び、薄肉部５を形成した。次いで、面取り状切欠き部１１、及び、薄肉部５により囲まれる空隙部にホットメルト系接着剤６を充填した後、薄肉部５を、外側からヒーター４で加熱しながら曲げ加工をしたところ、折り曲げ曲率半径は、３ｍｍとなった。
【００２８】
【実施例２】実施例１において、カッター８の切削深さを１．５ｍｍとし、他は同一条件としたところ、熱硬化性樹脂化粧板３の折り曲げ曲率半径は２ｍｍとなった。
【００２９】
【発明の効果】
請求項１の発明によれば、熱硬化性樹脂化粧板は、薄肉部において容易に曲げることができるので、折り曲げ曲率半径を極めて小さくすることができ、かつ、薄肉部が折り曲げられて面取り状切欠き部に沿うように被覆されているので、自然な曲面となる。ゆえに、この積層板は、曲げ部において外部からは直線状の形状感となって見えるので、外観形状として高い意匠性を与えることができる。
【００３０】
請求項２の発明によれば、請求項１の積層板を製造するにあたり、カッターによって面取り状切欠き部、及び、薄肉部が同時に形成されるので、製造工程が簡便となり、製造効率を高くすることができる。
【００３１】
請求項３の発明によれば、カッターの基材に対する切削深さを調整することにより、面取り状切欠きの大きさを変更することができ、もって、単一のカッターで、折り曲げ曲率半径の異なる積層板を得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a laminated board in which a thermosetting resin decorative board is coated in a series of curved surfaces from a flat portion to a side portion of a base material, and a method for manufacturing the same. More specifically, the present invention relates to a laminate capable of extremely reducing the bending radius of curvature of a thermosetting resin decorative board and a method for manufacturing the same.
[0002]
[Prior art]
A laminated board composed of a base material, a flat part of the base material, and a thermosetting resin decorative board coated in a series on the side edges, has a hard surface, is hardly damaged, and has excellent heat resistance. Furthermore, because of its rich design, it is widely used for various counters and kitchen doors.
[0003]
FIG. 8 shows an example of this laminated plate. Here, a partial cross-sectional view of a plate end portion of the laminated plate is shown. For the laminated plate 20, for example, a flat base material 21 made of a plywood is prepared, and a corner portion of the base material 21 is subjected to a curved surface processing to provide a curved surface portion 24. Next, a thermosetting resin decorative board 23 made of a melamine resin decorative board or the like is prepared, and the thermosetting resin decorative board 23 is placed along the flat portion, the curved surface portion 24, and the side end portion 22 of the base material 21. Glue. At this time, the bonding to the curved surface portion 24 is performed while heating the thermosetting resin decorative plate 23 and bending it by an external force. Such processing using a thermosetting resin decorative board is generally called post-form processing.
[0004]
By the way, in this laminated plate 20, the radius of curvature of the curved surface portion 24 is at least about 10 mm. This is because the thermosetting resin decorative board 23 has no flexibility. If the radius of curvature of the curved surface portion 24 is smaller than about 10 mm, the thermosetting resin decorative board 23 cannot be bent at the time of manufacturing the laminate 20. Otherwise, the thermosetting resin decorative board 23 may be damaged by bending it forcibly.
[0005]
On the other hand, there is a demand for better appearance and design in the curved surface portion 24 of the laminated plate 20. This means that it is desired to obtain a laminate 20 having a curvature radius of the curved surface portion 24 as small as possible, specifically, a curvature radius of about 5 mm or less. That is, if the radius of curvature of the curved surface portion 24 is smaller, for example, about 2 to 3 mm, the curved surface portion 24 looks linear from the outside and gives a sharp impression as an external shape. May be preferred by the user.
[0006]
By the way, in Patent Document 1, after a decorative material is attached to a base material, the base material on the back side of the decorative material is cut to form a curved surface forming portion, and a cutout is formed in the base material to form a curved surface. A technique has been disclosed in which a radius of curvature of a bent portion can be reduced to 5 mm or less by attaching a formed portion to a substrate after cutting.
[0007]
However, the technique of Patent Literature 1 presupposes a material that is extremely thin and can be easily bent, such as printing paper, attached board, cloth, and synthetic resin sheet, as a decorative material. Therefore, when a thermosetting resin decorative board is used as a decorative material like the laminated board 20, it is difficult to apply this technology.
[0008]

JP, 2002-337108, A
[Problems to be solved by the invention]
Therefore, the problem to be solved by the present invention is to provide a laminate in which a thermosetting resin decorative board is coated in a series of curved surfaces from a flat portion to a side portion of a substrate. And a method for manufacturing the same.
[0010]
[Means to solve the problem]
The invention of claim 1 made in order to solve the above-mentioned problem has a base material provided with a chamfered notch at a corner and a thin portion provided at a location corresponding to the chamfered notch. A laminate comprising a thermosetting resin decorative board, wherein the thermosetting resin decorative board is bent at the thin portion, and the chamfered notch is covered. It is. The chamfered notch is a notch provided at a corner of the base material, and is formed by chamfering the corner.
[0011]
That is, this laminated board is provided with a thin part in the thermosetting resin decorative board, and the thermosetting resin decorative board is thin and flexible in the thin part. The thin portion can be easily bent.
[0012]
In addition, since the thermosetting resin decorative board covers the chamfered notch along the chamfered notch in the thin portion, the bend of the thermosetting resin decorative board at this point is applied to the base material. A natural curved surface follows the shape of the chamfered notch without protruding. Therefore, in this laminate, the bending radius of curvature of the thermosetting resin decorative board is extremely small, and the laminate can be seen as a straight line from the outside.
[0013]
Here, the bending of the thermosetting resin decorative board may be performed while the hot-melt adhesive is filled in the chamfered notch portion, and the gap surrounded by the thin portion, and heating is performed from outside the thin portion. . By heating the thermosetting resin decorative board, the plasticity increases and it becomes easy to bend, and the heating melts the hot-melt adhesive, ensuring the adhesion between the base material and the thermosetting resin decorative board in the voids. Done.
[0014]
The invention according to claim 2 is the method for manufacturing a laminated board according to claim 1, wherein the step of forming the chamfered notch portion and the thin portion includes forming the notch cutting surface and the thin portion cutting surface. A method for manufacturing a laminated board, characterized in that it is a step of simultaneously forming with a cutter having the same.
[0015]
In the laminate according to claim 1, since the chamfered notch and the thin portion are formed at the contacting portions, this manufacturing method uses a cutter having a notch cutting surface and a thin portion cutting surface. Thus, the chamfered notch and the thin portion are formed at the same time.
[0016]
The invention according to claim 3 is the method according to claim 2, wherein the cutter has a variable cutting depth with respect to the base material.
[0017]
The bending process of the thermosetting resin decorative board in this laminated plate is to bend the thin portion and cover the chamfered notch, so that the radius of curvature of the bent portion at this time is the chamfered notch. It depends on the size of Here, if the cutting depth of the cutter with respect to the base material is changed, a chamfered notch portion of an arbitrary size can be obtained, so that if the cutting depth is made variable and the cutting depth is appropriately adjusted, it can be simply obtained. With one cutter, a laminated board having a bending radius of curvature of an arbitrary size can be obtained.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a plate end portion of a laminate 7 according to the present invention. The laminated board 7 includes the base material 1 and the thermosetting resin decorative board 3. Specifically, a chamfered notch 11 is formed at a corner of the base material 1, and a thin portion 5 is provided at a position corresponding to the chamfered notch 24 of the thermosetting resin decorative board 3. The thermosetting resin decorative board 3 is adhered to the flat portion, the chamfered notch portion 11, and the side end portion of the base material 1, and covers the base material 1 in a series. In particular, the thermosetting resin decorative board 3 is covered along the chamfered notch 11 by bending the thin portion 5. Further, the gap surrounded by the chamfered notch 24 and the thin portion 5 is filled with the hot melt adhesive 6.
[0019]
Next, a method of manufacturing the laminated plate 7 will be described. First, as shown in FIG. 2, a substrate 1 and a thermosetting resin decorative board 3 are prepared. As a material of the base material 1, an easily cut wood material, for example, a wood veneer, a wood plywood, a medium fiber board (MDF), a particle board, or the like is used. The shape is appropriately selected according to the use of the laminated board. . The resin of the thermosetting resin decorative board 3 may be melamine, dap, polyester, or the like, and these may be appropriately selected according to the use of the laminated board. Then, the thermosetting resin decorative plate 3 is adhered to the flat surface of the base material 1 while leaving the winding part 2 adhered to the side end.
[0020]
Next, as shown in FIG. 3, a chamfered notch 11 is provided at a corner of the substrate 1. Further, the thin portion 5 is provided at a position corresponding to the chamfered notch 24 of the thermosetting resin decorative board 3.
[0021]
Subsequently, as shown in FIG. 4, a hot-melt adhesive 6 is filled into the chamfered notch 11 and the gap surrounded by the thin portion 5, and the thin portion 5 is thermoset while being heated by the heater 4. The decorative resin plate 3 is bent, and the back surface side of the entangled portion 2 is adhered to the side surface of the substrate 1.
[0022]
By heating, the thermosetting resin decorative plate 3 increases the plasticity of the thin portion 5 and can be bent very easily. Therefore, by performing such a bending process, an extremely small radius of curvature of the bent portion of the thermosetting resin decorative plate 3 of about 2 to 3 mm can be obtained.
[0023]
Here, the chamfered notch portion 11 and the thin portion 5 shown in FIG. 4 may be formed simultaneously by using the cutter 8 shown in FIG. FIG. 6 is a partial cross-sectional view of the tip of the cutter 8 used in this processing. The cutter 8 has a notched cutting surface 9 and a thin-walled cutting surface 10. In actual processing, a rotary cutter having a plurality of cutters 8 connected in a circle is prepared, and the rotary cutter is rotated to perform a cutting process as shown in FIG.
[0024]
In the bending process of the thermosetting resin decorative board 3, since the thin portion 5 is covered while being bent along the chamfered notch 11, the bending radius of curvature of the thermosetting resin decorative board 3 is chamfered. This depends on the size of the notch 11.
[0025]
As can be seen from FIG. 5, the size of the chamfered notch 11 is determined by the cutting depth of the cutter 8 with respect to the substrate 1. Therefore, if the cutting depth of the cutter 8 is adjusted, the size of the chamfered notch 11 can be changed in processing. Therefore, if the cutting depth of the cutter 8 is adjusted at the time of manufacturing, it is possible to obtain a laminated board having the same material but different bending curvature radii of the thermosetting resin decorative board 3.
[0026]
Next, examples of the present invention will be described.
Example 1 As a material of a laminated plate 7, a substrate 1 made of plywood and a thermosetting resin decorative plate 3 made of a decorative melamine resin plate having a thickness of 0.8 mm were prepared. In addition, a rotary cutter was prepared using ten cutters 8 each having a tip end having a sectional shape shown in FIG. 7 and having a circular shape.
[0027]
After bonding the thermosetting resin decorative board 3 to the flat part of the base material 1 with a rubber-based adhesive, the cutting depth is 3 mm, and the thickness of the thin portion 5 of the thermosetting resin decorative board 3 is 0.4 mm. Then, the position of the cutter 8 was adjusted, and cutting was performed to form the chamfered notch portion 11 and the thin portion 5. Next, after filling the hot-melt adhesive 6 into the gap surrounded by the chamfered notch portion 11 and the thin portion 5, the thin portion 5 was bent while being heated by the heater 4 from the outside. The bending radius of curvature was 3 mm.
[0028]
Example 2 In Example 1, when the cutting depth of the cutter 8 was 1.5 mm and the other conditions were the same, the bending radius of the thermosetting resin decorative plate 3 was 2 mm.
[0029]
【The invention's effect】
According to the invention of claim 1, since the thermosetting resin decorative board can be easily bent at the thin portion, the bending radius of curvature can be made extremely small, and the thin portion is bent and chamfered. Because it is covered along the notch, it has a natural curved surface. Therefore, since the laminated plate looks like a linear shape from the outside at the bent portion, it is possible to give a high design property as an external shape.
[0030]
