Description
本発明は、縁なし畳及びその製法に関するものである。The present invention relates to an edgeless tatami mat and a method for producing the same.
最近では、畳の嗜好も変化しており、半畳の薄い縁なし畳がシンプルな感じがし、また、縁がないことによって広く見えるために好まれる傾向にある。洋間に部分的に畳敷きを形成するのに適しているからであるが、最初から和室の造りにし、これに全体的に畳を敷く、所謂、敷込みにも縁なし畳が使用される傾向にある。ところが、この縁なし畳は、従来の縁が付いている畳に比べると造りがかなり難しい。縁があれば、この縁で畳床の端の部分を隠せるからであるが、縁がないと、その体裁や精度が直接畳に表れるからである。Recently, the preference of tatami mats has also changed, and the semi-tatami thin rimless tatami feels simple and tends to be preferred because it looks wide due to the lack of rims. This is because it is suitable for partly forming a tatami mat between the oceans, but it is a trend to use a so-called rimless tatami for so-called laying. It is in. However, this edgeless tatami is much more difficult to build than conventional tatami mats. This is because if there is an edge, the edge portion of the tatami floor can be hidden by this edge, but if there is no edge, its appearance and accuracy appear directly in the tatami mat.
縁なし畳は、畳床と畳表を畳糸等で縫着するのではなく、畳床に貼った畳表の余部を畳床の裏面に折り返して接着剤で接着し、密着感があるものにしている。従って、畳床のコーナーの部分の畳表ををうまく処理しなければ、体裁の悪いものとなってしまう。Rimless tatami mats do not sew the tatami floor and the tatami mat with tatami thread etc., but fold the extra part of the tatami mat that has been affixed to the tatami floor to the back of the tatami floor and attach it with an adhesive to make it feel tight. Yes. Therefore, if the tatami mats at the corners of the tatami floor are not processed well, the appearance will be poor.
また、接着剤としては、溶剤系接着剤が多く使用されているが、畳表は、天然または人造のござ及び紙や竹の繊維を織ったものが多いから、溶液形態の溶剤系接着剤では畳表の中に浸透してしまい、十分な接着力が出ない。さらに、溶剤系接着剤には有機溶媒が使用されていることから、健康への影響も心配される。この他、敷込みに使用する畳では、寸法精度もかなりのものが要求されるが（半畳で±１ｍｍ）、これに縁なし畳で対応するには、誤差吸収の何らかの対策が必要とされる。Also, solvent-based adhesives are often used as adhesives, but tatami mats are often woven from natural or man-made ridges and paper and bamboo fibers. It penetrates into the inside and does not have sufficient adhesive strength. Furthermore, since an organic solvent is used for the solvent-based adhesive, there is a concern about the influence on health. In addition, tatami mats used for laying require a considerable dimensional accuracy (± 1 mm for half tatami mats), but some countermeasures for error absorption are required in order to support this with a rimless tatami mat. .
本発明は、このような課題を解決したものであり、畳表による畳床の被覆に際してコーナーの体裁を良くするとともに、寸法誤差を吸収できる縁なし畳とその製造方法を具現したものである。The present invention solves such problems, and embodies an edged tatami mat that can improve corner appearance and absorb dimensional errors when a tatami floor is covered with a tatami surface, and a manufacturing method thereof.
以上の課題の下、本発明は、請求項１に記載した、畳床の一面に畳表を四辺に余部を残して接着し、余部を他面に折り返して接着した縁なし畳において、余部をホットメルト糊によって畳床の側面は全高にわたって非接着状態に残して接着したことを特徴とする縁なし畳、及びこれにおいて、請求項２に記載した、余部のコーナーを、畳床の厚み分だけは畳床の辺と平行にカットするとともに、それを過ぎると、約４５°の斜め方向にカットした構成を提供したものである。Under the above-described problems, the present invention provides a marginal tatami mat that is bonded to one surface of the tatami floor with the tatami mats being left on the four sides, leaving the remaining portions folded and bonded to the other surface. The edge-less tatami mat is characterized in that the side surface of the tatami floor is adhered in a non-adhesive state over the entire height by the melt paste, and in this, the extra corner according to claim 2 is provided for the thickness of the tatami floor. In addition to being cut parallel to the side of the tatami floor, after passing through it, a configuration in which it is cut in an oblique direction of about 45 ° is provided.
また、本発明は、以上の縁なし畳の製造方法として、請求項４に記載した、畳床の一面に 畳表を四辺に余部を残して接着し、この余部にホットメルト糊を塗布して畳床の他面に折り返し、折り返した余部を畳床の側面を規制しながら熱加圧してホットメルト糊を溶解させるとともに、熱加圧した個所に冷風を供給してホットメルト糊を冷却して接着を完成させることを特徴とする縁なし畳の製造方法、及びこのホットメルト糊が、請求項５に記載した、パウダー状、フィルム状、ネット状、メルトガンに収容されたもの、のいずれかである手段にかかる縁なし畳の製造方法を提供したものである。Further, the present invention provides a method for producing the above-mentioned borderless tatami mat, wherein the tatami mat is bonded to one side of the tatami floor leaving a surplus portion on four sides, and hot melt paste is applied to the surplus portion to apply the tatami mat. Fold back to the other side of the floor and heat-press the remaining part of the tatami floor while regulating the side of the tatami floor to dissolve the hot-melt paste, and supply cold air to the hot-pressed area to cool and bond the hot-melt paste A method for producing a rimless tatami, characterized in that the hot melt paste is any one of powder, film, net, and melt gun. The manufacturing method of the borderless tatami concerning a means is provided.
本発明の縁なし畳によると、畳表の余部をホットメルト糊で接着することにより、早く確実に接着できる。加えて、溶剤等を使用しないから、健康面への悪影響もない。また、畳床の側面と畳表とを非接着状態にしたことにより、ある程度の弾力性が得られ、寸法誤差を吸収する。そして、これにおいて、畳表を畳床の厚み分だけは辺と並行にカットしたことにより、畳床のコーナーの稜線に沿わせることができる。さらに、これを過ぎると、約４５°の斜め方向にカットしたことにより、畳床に接着したときに畳表同士が重合するのを避けられる。According to the edgeless tatami mat of the present invention, the extra portion of the tatami surface can be bonded quickly and reliably by hot melt glue. In addition, since no solvents are used, there are no adverse health effects. In addition, since the side surface of the tatami floor and the tatami surface are not bonded, a certain degree of elasticity is obtained and dimensional errors are absorbed. In this case, the tatami mat is cut in parallel with the side by the thickness of the tatami floor, so that the tatami mat can be made to follow the ridgeline of the corner of the tatami floor. Furthermore, past this, the tatami mats can be prevented from overlapping when bonded to the tatami floor by cutting in an oblique direction of about 45 °.
以下、本発明の実施の形態を図面を参照して説明する。図１は本発明の一例を示す縁なし畳の裏面図であるが、この縁なし畳は、畳床１と畳表２からなる。畳床１は、インシュレーションボードと称されるものであり、樹脂、木質繊維等を７〜１５ｍｍ程度の厚みに押し固めたものであり、約９１０ｍｍ四方の大きさを有している（半畳の畳）。畳表２は、天然または人造のござ及び紙や竹の繊維を織った織布や不織布からなるもので、２〜５ｍｍ程度の厚みを有する。Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a rear view of an edgeless tatami showing an example of the present invention. This edgeless tatami comprises a tatami floor 1 and a tatami table 2. The tatami floor 1 is called an insulation board, which is made by pressing resin, wood fiber, etc. to a thickness of about 7 to 15 mm, and has a size of about 910 mm square (half tatami mat). tatami). The tatami mat 2 is made of a woven fabric or a non-woven fabric woven with natural or artificial woven paper and paper or bamboo fibers, and has a thickness of about 2 to 5 mm.
以上の畳表２を畳床１の一面に全面接着する。このとき使用する接着剤は何であってもよく、コスト面からは、溶剤系、水性エマルジョン系（これによると、環境面への影響もない）が適し、接着力や環境対応面からは、ホットメルト糊が適する。ここでいうホットメルト糊とは、溶融状態で塗布し、冷却によって固体状態に接合を形成する熱可塑性接着剤のことであり、固体状で供給され、有機溶剤を含有していないことから、取扱性に優れて地球環境に好ましい糊といえる。The above tatami mat 2 is bonded to the entire surface of the tatami floor 1. Any adhesive can be used at this time. From the cost standpoint, solvent-based and water-based emulsion systems (which have no environmental impact) are suitable. Melt glue is suitable. The hot melt paste here is a thermoplastic adhesive that is applied in a molten state and forms a bond in a solid state by cooling, and is supplied in a solid state and does not contain an organic solvent. It can be said to be an excellent paste for the global environment because of its excellent properties.
ホットメルト糊は、７０〜９０°以上に加熱すると、溶解して強力な接着力を派生させるもので、オレフィン系、ポリアミド系、エステル系と種々の素材のものがあるが、オレフィン系のものが価格や接着力或いは環境対応面の点で適する。また、その形態もパウダー状を始め、フィルム状、ネット状に成形したものの他、メルトガンに収容して溶解させたもの等様々なものがあるが、これに使用する場合は、接着面積が大きいこともあって予め面状に成形したものが適する。Hot-melt paste dissolves when heated to 70-90 ° or more and derives strong adhesive strength. There are various materials such as olefin, polyamide and ester, but olefin Suitable in terms of price, adhesive strength or environmental friendliness. In addition to powders, films, and nets, there are various forms such as melted in a melt gun. When used for this, the adhesive area must be large. For this reason, a sheet that has been previously formed into a planar shape is suitable.
以上の状態で畳表２を畳床１に貼着したとき、畳表２は畳床１の四辺外方に余部３を有するようにし、この余部３は、３０〜１００ｍｍ程度にする。そして、本発明では、畳表２の余部３のコーナーを、畳床１の厚みａ分だけは畳床１の辺と平行４にカットするとともに、それを過ぎると、約４５°の斜め方向５にカットする。従って、畳表２を畳床１の一面に接着するとき、平行４にカットしたその頂点を畳床１のコーナーに合わせて接着する必要がある。When the tatami mat 2 is stuck on the tatami floor 1 in the above state, the tatami mat 2 has a surplus portion 3 on the outer sides of the four sides of the tatami floor 1, and the surplus portion 3 is about 30 to 100 mm. In the present invention, the corner of the surplus portion 3 of the tatami table 2 is cut into 4 parallel to the side of the tatami floor 1 by the thickness a of the tatami floor 1, and after that, in an oblique direction 5 of about 45 °. Cut. Therefore, when the tatami mat 2 is bonded to one surface of the tatami floor 1, it is necessary to bond the apexes cut in parallel 4 to the corners of the tatami floor 1.
図２は余部３を畳床１に折り返して接着する状態を示す説明図であるが、このように畳表２が接着されていない面を上にして作業台の上に置き、余部３を折り返して畳床１に接着する。この接着もホットメルト糊を使用するが、この場合は、パウダー状のものやメルトガンに収容したものの方が必要な個所のみに散布できて好ましい。折り返した余部３を上から熱を加えて押圧すると、ホットメルト糊は溶解して畳床１と畳表２との間に介在し、これが冷却されると、両者は接着される。FIG. 2 is an explanatory view showing a state in which the surplus portion 3 is folded and bonded to the tatami floor 1, and is placed on the work table with the surface to which the tatami table 2 is not bonded facing up, and the surplus portion 3 is folded back. Adhere to tatami floor 1. For this bonding, hot-melt paste is also used, but in this case, a powder-like one or a one contained in a melt gun is preferable because it can be applied only to the necessary portions. When the folded back portion 3 is pressed by applying heat from above, the hot-melt paste is dissolved and interposed between the tatami floor 1 and the tatami surface 2, and when they are cooled, they are bonded together.
このようにしてコーナーを挟む二辺を接着すると、畳床１のコーナーにおいては、畳床１の厚みａだけその辺と平行４にカットしたことにより、この部分が畳床１のコーナーの稜線に綺麗に沿い、畳床１が露出した（口を開けた）部分や畳表１同士が重合した部分を現出しない。また、平行４にカットした部分を過ぎると、約４５°の斜め方向５にカットしてあるから、これも、畳床２の裏面に露出した部分や重合した部分を現出しないで接着される。但し、この部分の口開けや重合はコーナーほど厳重ではない。When the two sides sandwiching the corner are bonded in this way, the corner of the tatami floor 1 is cut by a thickness 4 of the tatami floor 1 in parallel with the side 4 so that this portion becomes the ridgeline of the corner of the tatami floor 1. Along the cleanliness, the part where the tatami floor 1 is exposed (opened) and the part where the tatami mats 1 overlap each other do not appear. Moreover, since it cuts in the diagonal direction 5 of about 45 degrees after passing the part cut in parallel 4, this is also bonded, without exposing the part exposed and the overlapped part on the back surface of the tatami floor 2 . However, the opening and polymerization of this part are not as severe as the corner.
図３は以上の畳の一部断面図であるが、以上の接着に際し、畳床１の側面は、畳表２を接着しないで残しておく。こうすると、この部分の畳表２はある程度弾力性があるものになり、寸法誤差を吸収できるものとなる。則ち、敷込みに際しては厳重な寸法管理が要求されるが、ある程度大きめに製作しておけば、寸法誤差を吸収できる。則ち、大きい場合は圧縮し、小さい場合は膨張して隣接するもの同士の隙間をなくす。FIG. 3 is a partial cross-sectional view of the above tatami mat, but the side surface of the tatami floor 1 is left without adhering the tatami surface 2 in the above bonding. If it carries out like this, the tatami surface 2 of this part will become a certain amount of elasticity, and can absorb a dimensional error. In other words, strict dimensional control is required for laying, but dimensional errors can be absorbed if manufactured to a certain extent. That is, when it is large, it is compressed, and when it is small, it expands to eliminate a gap between adjacent ones.
ところで、畳床１のコーナーでは、どうしても、畳表２が膨らみ、その稜線の部分では畳床１が口を開けがちである。そこで、畳床１の辺と平行４にカットする部分において、その頂点に非カット部分２ａを残し（畳表２の押抜き型にこれが可能なような細工をしておけばよい）、これをその部分にあてがい、接着剤で固めればよい。図４はこの状態を示す説明図であるが、こうすることで綺麗に補修できる。なお、残した畳表２の部分（繊維）２ａだけでは足らないときには、別のものを適宜足せばよい。By the way, at the corner of the tatami floor 1, the tatami floor 2 inevitably swells, and the tatami floor 1 tends to open its mouth at the ridgeline portion. Therefore, in the portion that is cut 4 parallel to the side of the tatami floor 1, the non-cut portion 2 a is left at the apex (the punching die of the tatami surface 2 may be crafted so as to be able to do this). Apply to the part and harden with adhesive. FIG. 4 is an explanatory diagram showing this state, but it can be repaired neatly by doing so. In addition, what is necessary is just to add another thing suitably, when only the part (fiber) 2a of the remaining tatami table 2 is not enough.
以上の縁なし畳の製造は以下のような製造装置によればよい。図５、図６はこの製造装置の要部の説明図であるが、ベース６の上にガイド７で上下動可能に案内される作業台８を設置する。この作業台８は、ばね９で上方に付勢されており、且つ、下降位置はストッパ１０で規制されるようになっている。作業台８は、その上に畳表２を一面に貼着した畳床１を非接着面を上にして置かれるものであるが、このとき、作業台８の幅は畳床１の大きさとほぼ等しくしてある。なお、作業第８は、畳床１全体の大きさを有する必要はなく、対向する二辺の部分に存在するものでよい。The manufacture of the rimless tatami may be performed by the following manufacturing apparatus. FIG. 5 and FIG. 6 are explanatory views of the main part of this manufacturing apparatus. On the base 6, a work table 8 guided by a guide 7 so as to be movable up and down is installed. The work table 8 is biased upward by a spring 9, and the lowered position is regulated by a stopper 10. The work table 8 is a table in which the tatami floor 1 with the tatami mat 2 attached on one side is placed with the non-adhesive surface facing upward. At this time, the width of the work table 8 is almost the same as the size of the tatami floor 1. Are equal. In addition, the work 8 does not need to have the size of the entire tatami floor 1 and may exist in two opposing sides.
作業台８の上方には、内寄りに押圧体１１が、外寄りに冷却体１２がエアーシリンダ１３、１４等で昇降可能に設けられている。このときの押圧体１１の外端は、少なくとも、折り返された余部３の端よりも内側に設定されている。また、作業台８の外方には、堰体１５がほぼ接触状態で設けられており、堰体１５の外方には、熱盤１６がエアーシリンダ１７で作業台８上方まで進退可能に設けられている。Above the work table 8, a pressing body 11 is provided inward and a cooling body 12 is provided outward by an air cylinder 13, 14. At this time, the outer end of the pressing body 11 is set at least inside the end of the folded back portion 3. In addition, a weir body 15 is provided in contact with the outside of the work table 8, and a hot platen 16 is provided on the outside of the weir body 15 so that the air cylinder 17 can be advanced and retracted to the upper side of the work table 8. It has been.
このとき、堰体１５の高さは、作業台８が下降したときに、その上に載っている畳床１の高さと等しいかやや低い程度に設定されている。これにより、畳表２が添着した畳床１の側面が堰体１５で規制されることになり、その形状及び寸法が確実になる。また、熱盤１６は、その下面が堰体１５を越えられるものであり、進出したときには、冷却体１２を越えて押圧体１１近くまで入り込むように設定されている。At this time, the height of the weir body 15 is set to a level that is equal to or slightly lower than the height of the tatami floor 1 placed on the work table 8 when it is lowered. As a result, the side surface of the tatami floor 1 to which the tatami mat 2 is attached is regulated by the weir body 15, and the shape and dimensions thereof are ensured. Moreover, the lower surface of the hot platen 16 can pass over the weir body 15, and is set so as to enter the vicinity of the pressing body 11 beyond the cooling body 12 when advanced.
以上の製造装置による縁なし畳の製造は以下のような工程をとる。
１）畳床の一面に畳表を四辺に余部を残して全面接着する工程
このとき、余部３のコーナーが畳床１のコーナーに位置が合わされなければならないのは上述したとおりである。The manufacture of borderless tatami using the above manufacturing apparatus takes the following steps.
1) Step of adhering the tatami mat to one side of the tatami floor, leaving the surplus parts on all sides, leaving the surplus parts on the entire surface At this time, the corners of the surplus part 3 must be aligned with the corners of the tatami floor 1 as described above.
２）畳床に折り返される余部の面にホットメルト糊粉を散布する工程
このとき、押圧体１１や冷却体１２で畳床１を作業台８に押えておくと、畳床１が固定されて作業がし易い。加えて、堰体１５が畳表２を添着した畳床１の側面を規制するものになり、寸法と形状の保持を確実にする。また、ホットメルト糊粉の散布は自動でしてもよいが、手作業でしてもよい。2) Step of spraying hot melt paste powder on the surplus surface folded back to the tatami floor At this time, if the tatami floor 1 is pressed against the work table 8 by the pressing body 11 or the cooling body 12, the tatami floor 1 is fixed. Easy to work. In addition, the weir body 15 regulates the side surface of the tatami floor 1 to which the tatami surface 2 is attached, thereby ensuring the retention of dimensions and shape. Moreover, the hot melt paste powder may be sprayed automatically or manually.
３）熱盤で余部を折り返して中央側に押しながら畳床に押し付け、ホットメルト糊を溶解する工程
熱盤１６を進出させると、余部３が折り返されるが、このとき、熱盤１６の下面を畳床１に折り返された畳表１の上面よりやや低く設定しておくと、余部３を中央側に押しやることになり、畳表２が畳床１を緊縮してより強い締めができるし、角も立ったものになる。これによると、余部３にホットメルト糊が散布されていたとしても、畳床１の側面は接着されない。さらに、このとき、冷却体１２を上昇させて熱盤１６との干渉を避ける。この状態で熱盤１６を停止させると、ホットメルト糊は溶解する。なお、ホットメルト糊をメルトガンに収容したものによると、敢えて熱盤による加熱を必要としないこともある。3) Fold the surplus part with a hot plate and press it against the tatami floor while pushing it to the center side. When the hot platen 16 is advanced, the surplus part 3 is folded back. If it is set a little lower than the upper surface of the tatami table 1 folded back to the tatami floor 1, the extra part 3 will be pushed to the center side, and the tatami table 2 can tighten the tatami floor 1 to tighten it more strongly, It will stand. According to this, even if the hot melt paste is sprayed on the surplus portion 3, the side surface of the tatami floor 1 is not bonded. Further, at this time, the cooling body 12 is raised to avoid interference with the hot platen 16. When the hot platen 16 is stopped in this state, the hot melt paste is dissolved. In addition, according to the hot melt paste contained in the melt gun, there is a case where heating with a hot plate is not required.
４）溶解されたホットメルト糊が介在する余部に冷風を送ってホットメルト糊を冷却して接着を確実にする工程
溶解したホットメルト糊は冷却されなければ、強い接着力は派生しない。そこで、自然冷却を待っていたのでは効率が悪いから、強制冷却させる。強制冷却は、熱盤１６を後退させ（畳床１は押圧体１１で押えてその側面を堰体１５で規制した状態は保持しておく）、冷却体１２を余部３の上まで下降させて行う。このため、冷却体１２には、上下に貫通孔１８が形成され、これに配管１９で冷風が供給されるようになっている。ホットメルト糊が冷却すると、その接着は完全なものになるが、このように、熱盤１６による加熱と冷却体１２による冷却を連続して行うことにより、接着が短時間で完全にできることになり、非常に能率のよいものとなる。4) Step of cooling the hot melt paste to ensure the adhesion by sending cold air to the surplus portion where the melted hot melt paste intervenes. If the melted hot melt paste is not cooled, strong adhesive strength is not derived. Therefore, forcibly cooling because waiting for natural cooling is inefficient. Forcible cooling is performed by retracting the hot platen 16 (the tatami floor 1 is held by the pressing body 11 and the side surface is regulated by the weir body 15), and the cooling body 12 is lowered onto the surplus portion 3. Do. For this reason, the cooling body 12 is formed with through holes 18 in the upper and lower sides, and cold air is supplied to the through holes 18 through the pipes 19. When the hot melt paste is cooled, the bonding becomes complete. In this way, by continuously performing heating by the hot platen 16 and cooling by the cooling body 12, the bonding can be completed in a short time. It will be very efficient.
以上の操作は、畳床１の対向する二辺で行われるから、同様の操作を他の二辺で行えば、縁なし畳は製作される。なお、このとき、畳床１のコーナーの補修をすることがあるのは上述したとおりである。Since the above operation is performed on the two opposite sides of the tatami floor 1, if the same operation is performed on the other two sides, a borderless tatami is produced. At this time, the corner of the tatami floor 1 may be repaired as described above.
