Description

本発明は、床材の製造方法に関する。   The present invention relates to a method for manufacturing a flooring.

従来から、木質基材の表面に化粧シートを備えた木質化粧板の表面と側面との間の角部を面取り加工し、塗装仕上げを施した床材が知られている(例えば、特許文献1参照)。この床材は、複数枚の床材同士を接合して敷設した時に、接合部に断面V字状の溝が形成され、この溝によって、接合部に生じる隙間や段差が目立たないようにしている。また、床材の表面に、接合部の断面V字状の溝と略同一形状の化粧溝を形成することにより、接合部の位置を目立たなくするとともに装飾的効果を向上させることも行われている。   2. Description of the Related Art Conventionally, floor materials are known in which corner portions between the surface and side surfaces of a wooden decorative board provided with a decorative sheet on the surface of a wooden base material are chamfered to give a paint finish (for example, Patent Document 1). reference). In this floor material, when a plurality of floor materials are joined to each other and laid, a groove having a V-shaped cross section is formed in the joint portion so that a gap or a step generated in the joint portion is not conspicuous. . Moreover, by forming a decorative groove having substantially the same shape as the V-shaped groove of the joint portion on the surface of the flooring, the position of the joint portion is made inconspicuous and the decorative effect is improved. Yes.

別の床材として、木質基材の表面にオレフィン樹脂製基材と化粧シートと塗膜層とからなる化粧層を設け、その四周上縁に面取り加工を施し、面取り部の深さを化粧層の厚みと略同等以下の深さに形成した床材も知られている(例えば、特許文献2参照)。この床材は、面取り面に木質基材が露出せず、木質基材の導管や木繊維の毛羽立ち等に由来する粗面が現出しないので、面取り面が美麗である。   As another flooring material, a decorative layer consisting of an olefin resin base material, a decorative sheet, and a coating layer is provided on the surface of the wooden base material, and chamfering is applied to the upper edge of the four circumferences so that the depth of the chamfered portion is the decorative layer. A flooring formed to a depth substantially equal to or less than the thickness of the sheet is also known (for example, see Patent Document 2). This floor material has a beautiful chamfered surface because the wooden base material is not exposed on the chamfered surface, and a rough surface derived from a conduit of the wooden base material or fluffing of the wooden fiber does not appear.

特許文献1の床材においては、塗装仕上げは、スポンジロールコーターやフローコーター等の塗装手段によって床材の表面と面取り面とを塗料で同時着色した後に、床材の表面の不要な塗料をかきとるなどして行われる。このため、大量の塗料を要するなどコスト高となる。さらに床材の表面を溶剤等で洗浄することもあり、作業環境の悪化やその洗浄に要するコスト等の問題も懸念される。   In the flooring of Patent Document 1, the finish of painting is done by simultaneously coloring the surface of the flooring and the chamfered surface with a paint by a coating means such as a sponge roll coater or a flow coater, and then scraping unnecessary paint on the surface of the flooring. It is done by taking. For this reason, a large amount of paint is required, resulting in high costs. Further, the surface of the flooring may be washed with a solvent or the like, and there are concerns about problems such as deterioration of the working environment and cost required for the washing.

特許文献2の床材は、面取り面が美麗であるため塗装仕上げを施さなくてもよいが、複数枚の床材同士を接合して敷設した際、接合部に生じる隙間や段差を目立たなくしたり、装飾的効果を向上させるためには一定の深さ以上の面取り部を形成することが求められる。このためには、オレフィン樹脂製基材、化粧シート、又は塗膜層の厚みを厚くして化粧層を厚くする必要がありコスト高となる。
なお、化粧シートを貼り付ける前の木質基材の角部を面取り加工し、木質基材の表面と面取り加工した面に連続して化粧シートを貼り付けることも検討されているが、縦横の4方向共に貼り付けることは困難であった。
The flooring of Patent Document 2 does not have to be painted because the chamfered surface is beautiful, but when a plurality of flooring materials are joined together and laid, In order to improve the decorative effect, it is required to form a chamfered portion having a certain depth or more. For this purpose, it is necessary to increase the thickness of the base material made of olefin resin, the decorative sheet, or the coating layer to increase the thickness of the decorative layer, resulting in high costs.
In addition, it is also considered to chamfer the corners of the wooden base material before attaching the decorative sheet, and to apply the decorative sheet continuously to the surface of the wooden base material and the chamfered surface. It was difficult to paste both directions.

本発明は、以上の事情に鑑みてなされたものであり、複数枚の床材同士を接合して敷設した際、接合部に生じる隙間や段差を目立たなくしたり、装飾的効果を向上させたりすることができる床材を低コストで製造できる床材の製造方法を提供することを課題とする。   The present invention has been made in view of the above circumstances, and when a plurality of flooring materials are joined and laid, the gaps and steps generated in the joined portion are made inconspicuous, and the decorative effect is improved. It is an object of the present invention to provide a method for manufacturing a floor material that can manufacture a floor material that can be manufactured at low cost.

以下、図面を参照して本発明の床材の製造方法の一実施形態について説明する。   Hereinafter, an embodiment of a flooring manufacturing method of the present invention will be described with reference to the drawings.

図1は、本発明の床材の製造方法の一実施形態を工程順に示した模式図であり、図2は、本発明の床材の製造方法で製造された床材の一実施形態を示す斜視図である。なお、以下の実施形態において、長手方向とは、図1(a)(b)では紙面貫通方向、図1(c)(d)では紙面左右方向であり、短手方向とは、図1(a)(b)では紙面左右方向、図1(c)(d)では紙面貫通方向として説明する。   FIG. 1 is a schematic diagram showing an embodiment of a flooring manufacturing method of the present invention in the order of steps, and FIG. 2 shows an embodiment of a flooring manufactured by the flooring manufacturing method of the present invention. It is a perspective view. In the following embodiments, the longitudinal direction is the paper surface penetrating direction in FIGS. 1A and 1B, the paper surface left and right directions in FIGS. 1C and 1D, and the short direction is FIG. In FIGS. 1 (a) and 1 (b), the description will be made in the left-right direction of the paper, and in FIGS.

図1(a)に示される木質基材1は、周囲の4側面のうち長手方向に沿う一対の側面1b,1bの一方に凸状の雄実2が形成され、他方に凹状の雌実3が形成されている。雄実2と雌実3は、それぞれ、複数枚の図2に示される床材40が建物の床下地部に敷設されるとき、隣接して配置される2枚の床材40の間において雄実2が雌実3に嵌合可能な形状を有している。具体的には、雄実2の外周形状と雌実3の内周形状が略一致している。このような雄実2及び雌実3は、木質基材1の長手方向に沿う一対の側面1b,1bだけでなく、木質基材1の短手方向に沿う一対の側面1c,1cにも同じように形成されている(図1(c)(d)、図2参照)。   A wooden base material 1 shown in FIG. 1 (a) has a convex male fruit 2 formed on one of a pair of side surfaces 1b, 1b along the longitudinal direction among four surrounding side surfaces, and a concave female fruit 3 on the other side. Is formed. Each of the male fruit 2 and the female fruit 3 is a male between two floor materials 40 arranged adjacent to each other when a plurality of floor materials 40 shown in FIG. The fruit 2 has a shape that can be fitted to the female fruit 3. Specifically, the outer peripheral shape of the male fruit 2 and the inner peripheral shape of the female fruit 3 are substantially the same. Such male fruit 2 and female fruit 3 are the same not only for the pair of side surfaces 1b and 1b along the longitudinal direction of the wooden substrate 1, but also for the pair of side surfaces 1c and 1c along the short direction of the wooden substrate 1. (See FIGS. 1C, 1D, and 2).

木質基材1の表面1aと長手方向に沿う側面1bとの間の境界部には、面取り面4が長手方向に沿って形成されている。この面取り面4は、例えば、木質基材1の表面1aと側面1bとの間の角部を鋸やルーター等の切削工具を用いて切削するなど面取り加工することによって形成される。本実施形態では面取り面4を平面状(C面取り)に形成しているが、断面円弧状の曲面(R面取り)に形成することもできる。   A chamfered surface 4 is formed along the longitudinal direction at the boundary between the surface 1a of the wooden substrate 1 and the side surface 1b along the longitudinal direction. The chamfered surface 4 is formed, for example, by chamfering the corner between the surface 1a and the side surface 1b of the wooden substrate 1 using a cutting tool such as a saw or a router. In the present embodiment, the chamfered surface 4 is formed in a flat shape (C chamfer), but may be formed in a curved surface (R chamfer) having an arcuate cross section.

面取り面4がC面取りの場合、複数枚の床材40同士を接合して敷設した時に、接合部に断面V字状の溝を目地などとして形成する。この溝によって、接合部に生じる隙間や段差が目立たないようにしている。また、床材40の敷設によって形成される床面に立体感を現出させるなど装飾的効果を向上させてもいる。なお、面取り面4がR面取りの場合には、接合部に断面U字状の溝を形成する。   When the chamfered surface 4 is a C chamfer, when a plurality of floor materials 40 are joined and laid, a groove having a V-shaped cross section is formed as a joint or the like in the joint. This groove prevents a gap or a step generated in the joint from being noticeable. In addition, the decorative effect is improved by, for example, making a three-dimensional appearance appear on the floor surface formed by laying the flooring 40. When the chamfered surface 4 is an R chamfer, a U-shaped groove is formed in the joint.

木質基材1は、表面1aに、接合部の溝と略同一形状の化粧溝5が長手方向にわたって形成されている。本実施形態では、面取り面4がC面取りであるため、断面V字形状の化粧溝5が形成されている。面取り面4がR面取りの場合には断面U字形状の化粧溝5が形成される。この化粧溝5は上記したような切削工具を用いて木質基材1の表面1aを切削するなどして形成される。この化粧溝5も、複数枚の床材40同士を接合して敷設した時に、床面に立体感を現出させるなどの装飾的効果を有する。また、接合部の位置を目立たなくする効果も有する。   The wood substrate 1 has a decorative groove 5 formed in the longitudinal direction in the surface 1a and having substantially the same shape as the groove of the joint. In the present embodiment, since the chamfered surface 4 is a C chamfer, a decorative groove 5 having a V-shaped cross section is formed. When the chamfered surface 4 is an R chamfer, a decorative groove 5 having a U-shaped cross section is formed. The decorative groove 5 is formed by, for example, cutting the surface 1a of the wooden substrate 1 using a cutting tool as described above. This decorative groove 5 also has a decorative effect such that a three-dimensional effect appears on the floor surface when a plurality of floor materials 40 are joined and laid. Moreover, it has the effect of making the position of the joint portion inconspicuous.

木質基材1はとしては、合板、パーティクルボード(Particle Board)、中密度繊維板(Medium Density Fiberboard:MDF)、木粉と樹脂の混合物を板状に成形して形成される混合ボード(Wood Plastic Board:WPB)、配向性ストランドボード(Oriented Strand Board:OSB)等を挙げることができる。または、これらを複合したものを木質基材1とすることもできる。例えば、合板の表面にMDFやWPBを接着して複合化したものを木質基材1として使用することができる。   The wood substrate 1 includes plywood, particle board, medium density fiberboard (MDF), and a mixed board formed by molding a mixture of wood powder and resin into a plate shape (Wood Plastic). Board: WPB), orientated strand board (OSB), and the like. Or what combined these can also be used as the wooden base material 1. FIG. For example, a composite material obtained by bonding MDF or WPB to the surface of a plywood can be used as the wood substrate 1.

次に、図1(b)に示されるように、木質基材1の表面1aに化粧シート6を積層して木質化粧板10を得る。
化粧シート6は、熱可塑性樹脂製のシートの表面や裏面に絵柄層を設けた単層構成のものや、絵柄層及び熱可塑性樹脂層を積層した複層構成のもの等を挙げることができる。
Next, as shown in FIG. 1B, a decorative sheet 6 is laminated on the surface 1 a of the wooden substrate 1 to obtain a wooden decorative board 10.
Examples of the decorative sheet 6 include a single layer structure in which a pattern layer is provided on the front and back surfaces of a thermoplastic resin sheet, and a multilayer structure in which a pattern layer and a thermoplastic resin layer are laminated.

化粧シート6のシートや熱可塑性樹脂層を構成する熱可塑性樹脂としては、例えばポリオレフィン系樹脂、ポリエステル系樹脂、アクリル系樹脂、ポリスチレン系樹脂、ポリアミド系樹脂、ポリ塩化ビニル樹脂等を使用することができる。中でも、床材としての表面物性や加工性、経済性、廃棄性等を考慮すると、ポリオレフィン系樹脂やポリエステル系樹脂を使用することが望ましい。   As the thermoplastic resin constituting the sheet of the decorative sheet 6 and the thermoplastic resin layer, for example, a polyolefin resin, a polyester resin, an acrylic resin, a polystyrene resin, a polyamide resin, a polyvinyl chloride resin, or the like may be used. it can. Among these, it is desirable to use a polyolefin-based resin or a polyester-based resin in consideration of surface properties, processability, economic efficiency, discardability, and the like as a flooring material.

化粧シート6の厚みは、コストや加工性を考慮すると、薄いものを採用することが望ましい。   As for the thickness of the decorative sheet 6, it is desirable to adopt a thin one in consideration of cost and workability.

化粧シート6は接着剤を用いて木質基材1の表面1aに積層される。接着剤としては、接着後の耐水性に優れた接着剤を使用することが望ましい。具体例として、エチレン−酢酸ビニル共重合体系エマルジョン型接着剤、2液硬化型ウレタン系接着剤、1液湿気硬化型ウレタン系ホットメルト接着剤等を挙げることができる。   The decorative sheet 6 is laminated on the surface 1a of the wooden substrate 1 using an adhesive. As the adhesive, it is desirable to use an adhesive having excellent water resistance after bonding. Specific examples include an ethylene-vinyl acetate copolymer emulsion adhesive, a two-component curable urethane-based adhesive, a one-component moisture-curable urethane-based hot melt adhesive, and the like.

化粧シート6を木質基材1の表面1aに積層するに際しては、狭幅ロール等を用いて木質基材1の表面1aの化粧溝5の内面及び長手方向に沿って形成された面取り面4に化粧シート6を沿わせて積層する。   When laminating the decorative sheet 6 on the surface 1a of the wooden substrate 1, the inner surface of the decorative groove 5 on the surface 1a of the wooden substrate 1 and the chamfered surface 4 formed along the longitudinal direction using a narrow roll or the like. The decorative sheets 6 are laminated along.

次に、図1(c)に示されるように、木質化粧板10の表面10aと短手方向に沿う側面10bとの間の角部を上記したような切削工具を用いて木質基材1に達するように面取り加工する。これによって、木質化粧板10の表面10aと短手方向に沿う側面10bとの間の境界部に、木質基材1が露出する面取り面11が短手方向に沿って形成される。本実施形態では面取り面11を平面状(C面取り)に形成しているが、断面円弧状の曲面(R面取り)に形成することもできる。   Next, as shown in FIG. 1 (c), the corner portion between the surface 10a of the wooden decorative board 10 and the side surface 10b along the short direction is applied to the wooden substrate 1 using the cutting tool as described above. Chamfering to reach. As a result, a chamfered surface 11 from which the wooden substrate 1 is exposed is formed along the short direction at the boundary between the surface 10a of the wooden decorative board 10 and the side surface 10b along the short direction. In the present embodiment, the chamfered surface 11 is formed in a flat shape (C chamfer), but may be formed in a curved surface (R chamfer) having an arcuate cross section.

次に、図1(d)に示されるように、塗料供給部材20を用いて面取り面11に塗料を塗布して面取り面11を着色塗装する。   Next, as shown in FIG. 1 (d), the chamfered surface 11 is colored and painted by applying a paint to the chamfered surface 11 using the paint supply member 20.

塗料としては、化粧シート6の表面6aの色調と近似した色調を有するものを使用することが望ましい。化粧シート6の表面6aの色調と後述する面取り面11の着色塗装膜の色調が近似したものとなるため、より意匠性に優れた床材を得ることができる。   As the paint, it is desirable to use a paint having a color tone approximate to the color tone of the surface 6a of the decorative sheet 6. Since the color tone of the surface 6a of the decorative sheet 6 is similar to the color tone of the colored coating film of the chamfered surface 11 described later, a flooring material with better design can be obtained.

塗料供給部材20は、合成樹脂製のもの、ゴム製のもの、金属製のもの等、特に問わないが、安価で加工しやすい素材を用いることが好ましい。また、その形状も、化粧シート6の表面6aに対して非接触状態で木質化粧板10の面取り面11と側面10bとの間の稜部12と接触可能であれば、平板状、曲面板状、柱状、円錐状、円錐台状等、特に問わない。本実施形態では円錐台状の塗装ロール21を塗料供給部材20として使用している。この塗装ロール21は、円錐台の側面に対応する部分がロール面22とされている。   The coating material supply member 20 is not particularly limited, such as a synthetic resin material, a rubber material, or a metal material, but it is preferable to use a material that is inexpensive and easy to process. Moreover, if the shape can also contact the ridge part 12 between the chamfered surface 11 and the side surface 10b of the wooden decorative board 10 in a non-contact state with respect to the surface 6a of the decorative sheet 6, a flat plate shape or a curved plate shape , Columnar, conical, frustoconical, etc. In the present embodiment, a frustoconical coating roll 21 is used as the coating material supply member 20. The coating roll 21 has a roll surface 22 at a portion corresponding to the side surface of the truncated cone.

塗装ロール21を用いて木質化粧板10の面取り面11を着色塗装するにあたっては、木質化粧板10の化粧シート6側の面を下側に向けた状態で行う。
塗装ロール21は、その上側に位置する部分が木質化粧板10の稜部12に接触するように、かつ、塗装ロール21が化粧シート6の表面6aと接触しないように、回転軸23を中心に回転可能に軸支されている。また、塗装ロール21のロール面22と木質化粧板10の面取り面11とは稜部12を除いて非接触状態とされ、塗装ロール21のロール面22と木質化粧板10の面取り面11との間には間隙Qが形成されている。塗装ロール21の下方には塗料30を貯留した塗料貯留槽31が設置されている。この塗料貯留槽31は、塗装ロール21の、下側に位置する部分が塗料貯留槽31の塗料30に浸漬するように配置されている。塗装ロール21を回転させることで塗装ロール21のロール面22全周に塗料30を行き渡らせて間隙Qに塗料を供給することができる。
When the chamfered surface 11 of the wooden decorative board 10 is colored and painted using the coating roll 21, the decorative sheet 6 side of the wooden decorative board 10 is directed downward.
The coating roll 21 is centered on the rotation shaft 23 so that the upper part thereof is in contact with the ridge 12 of the wooden decorative board 10 and the coating roll 21 is not in contact with the surface 6a of the decorative sheet 6. It is pivotally supported so that it can rotate. Further, the roll surface 22 of the coating roll 21 and the chamfered surface 11 of the wooden decorative board 10 are in a non-contact state except for the ridge portion 12, and the roll surface 22 of the coating roll 21 and the chamfered surface 11 of the wooden decorative board 10 are not in contact with each other. A gap Q is formed between them. A coating material storage tank 31 storing the coating material 30 is installed below the coating roll 21. The paint reservoir 31 is arranged so that the lower part of the coating roll 21 is immersed in the paint 30 of the paint reservoir 31. By rotating the coating roll 21, the coating material 30 can be spread over the entire circumference of the roll surface 22 of the coating roll 21 and supplied to the gap Q.

木質化粧板10を短手方向に沿って送り出し、塗装ロール21を木質化粧板10の送り出し方向と同方向に回転させることで、木質化粧板10の面取り面11に短手方向全長に亘って塗料30を塗布して面取り面11を着色塗装することができる。必要に応じて塗布面を乾燥処理する。塗装ロール21と化粧シート6の表面6aとは非接触状態とされているので、化粧シート6の表面6aを着色塗装することなく、短手方向に沿う面取り面11のみを着色塗装することができる。この着色塗装によって面取り面11に露出する木質基材1が覆い隠されるので、木質基材1の色調と化粧シート6の色調との相違による違和感が低減し、意匠性に優れた図2に示される床材40を得ることができる。   The wooden decorative board 10 is sent out along the short direction, and the paint roll 21 is rotated in the same direction as the feeding direction of the wooden decorative board 10, so that the paint is applied to the chamfered surface 11 of the wooden decorative board 10 over the entire length in the short direction. 30 can be applied and the chamfered surface 11 can be colored. The coated surface is dried as necessary. Since the coating roll 21 and the surface 6a of the decorative sheet 6 are in a non-contact state, only the chamfered surface 11 along the short direction can be colored and coated without coloring the surface 6a of the decorative sheet 6. . Since the wooden base material 1 exposed on the chamfered surface 11 is covered and covered by this colored coating, a sense of incongruity due to the difference between the color tone of the wooden base material 1 and the color tone of the decorative sheet 6 is reduced, and the design is excellent in FIG. Floor material 40 can be obtained.

塗装ロール21における木質化粧板10との接触面24と木質化粧板10の面取り面11との接触角度θ(塗装ロール21のロール面22と木質化粧板10の面取り面11とのなす角度)が20°以内となるように塗装ロール21を配置することが好ましい。より好ましくは、3°以上15°以内である。20°以内であれば、塗装ロール21のロール面22から間隙Qに塗料30を効率よく供給することができ、また、間隙Qに供給された塗料30を木質化粧板10の面取り面11に効果的に接触させて面取り面11に塗布することができる。さらにまた、間隙Qに供給された塗料30の、化粧シート6の表面6a等の木質化粧板10の面取り面11以外の箇所への回り込みを抑え、面取り面11以外の箇所の着色塗装を抑えることができる。   The contact angle θ between the contact surface 24 of the painting roll 21 with the wooden decorative board 10 and the chamfered surface 11 of the wooden decorative board 10 (the angle formed between the roll surface 22 of the painting roll 21 and the chamfered face 11 of the wooden decorative board 10). It is preferable to arrange the coating roll 21 so as to be within 20 °. More preferably, it is 3 ° or more and 15 ° or less. If it is within 20 °, the paint 30 can be efficiently supplied from the roll surface 22 of the coating roll 21 to the gap Q, and the paint 30 supplied to the gap Q is effective on the chamfered surface 11 of the wooden decorative board 10. And can be applied to the chamfered surface 11.
