Description

本発明は、２枚のビニールシートを接合するための方法に関するものである。   The present invention relates to a method for joining two vinyl sheets.

従来、２枚のビニールシートを接合する方法としては、該2枚のビニールシートの端辺同士を接着剤を介して重ね合わせ、必要に応じて圧力を加えることにより行なわれてきた。   Conventionally, as a method of joining two vinyl sheets, the ends of the two vinyl sheets are overlapped with each other through an adhesive, and pressure is applied as necessary.

かかる従来の接合方法によると、接合部分が接着層並びにビニールシートの肉厚分だけ段差を生じ、すなわち接合部分全体の肉厚はビニールシートの２倍以上となってしまうこととなる。また、接合部分の強度にも問題があり、接合部分以外のビニールシートの引張り強度に比して、約１／２以下の強度となってしまう。   According to such a conventional joining method, the joining portion has a level difference corresponding to the thickness of the adhesive layer and the vinyl sheet, that is, the thickness of the entire joining portion is twice or more that of the vinyl sheet. In addition, there is a problem with the strength of the joined portion, and the strength is about ½ or less compared to the tensile strength of the vinyl sheet other than the joined portion.

さらに従来の接合方法によれば、両ビニールシートの重合部を完全に接着することは困難であって、夫々の端辺箇所に、通称耳と呼ばれる接着されずに浮いた状態にある箇所が発生してしまうこととなる。かかる耳の発生は、ビニールシートの遮断機能を低下させ、詳しくは、該耳の部分から埃や水滴の侵入を許すことになってしまう。   Furthermore, according to the conventional joining method, it is difficult to completely bond the overlapped portions of both vinyl sheets, and there are places that are in a floating state, not commonly called ears, at the respective edge portions. Will end up. The occurrence of such ears lowers the blocking function of the vinyl sheet, and more specifically, allows entry of dust and water droplets from the ear part.

上記問題点を解決すべく、ウエルダー溶着によるビニールシートの接合方法も、従来より行なわれている。しかしながら、該ウエルダー溶着によると、溶着部分そのものは強度的に強いが、際部分は金型で押し込まれているため凹んで薄くなり、実験によれば、溶着部分以外のビニールシートの引張り強度に比して約１／２程度の強度しか有していないという結果である。したがって、その強度的な弱さから、強い引張りに対して溶着部分が破断する恐れがある。   In order to solve the above problems, a method of joining vinyl sheets by welder welding has been conventionally performed. However, according to the welder welding, the welded part itself is strong in strength, but the edge part is depressed with a mold so that it becomes concave and thin. According to experiments, it is compared with the tensile strength of the vinyl sheet other than the welded part. As a result, it has only about half the strength. Therefore, the welded part may be broken due to its strong weakness.

Can be provided.

以下、本発明にかかるビニールシート１の接合方法の実施形態について、図面を参照しながら説明する。   Hereinafter, embodiments of a method for joining vinyl sheets 1 according to the present invention will be described with reference to the drawings.

図１は、本発明にかかるビニールシート１の接合方法の第一の実施形態を示す概略説明図である。   FIG. 1 is a schematic explanatory view showing a first embodiment of a method for joining vinyl sheets 1 according to the present invention.

該第一の実施形態は、まず初めに、図１（ａ）に示すように、一方のビニールシート１の端辺と、他方のビニールシート１の端辺とを重ね合わせ、2枚のビニールシート１の重合部２を得る（第一工程）。   In the first embodiment, first, as shown in FIG. 1A, the end side of one vinyl sheet 1 and the end side of the other vinyl sheet 1 are overlapped to form two vinyl sheets. 1 superposed part 2 is obtained (first step).

このとき、該重合部２の幅は、１〜１０ｍｍの範囲内とすることが望ましい。１ｍｍ未満とすると、接合後の接合部分の強度が弱くなる恐れがあるとともに、１０ｍｍより幅を大きくした場合には、１〜１０ｍｍの範囲内で接合した場合と比して強度的に変化するものではなく、かえって後述する熱溶解や加圧、冷却のための時間・労力を増すこととなるからである。   At this time, the width of the overlapping portion 2 is preferably within a range of 1 to 10 mm. If it is less than 1 mm, the strength of the joined portion after joining may be weakened, and when the width is made larger than 10 mm, the strength changes compared to the case of joining within the range of 1 to 10 mm. Instead, the time and labor for heat melting, pressurization, and cooling described later are increased.

次いで、図１（ｂ）に示すように、前記第一工程により得られた2枚のビニールシート１の重合部付近に、該ビニールシート１が溶解するために必要な熱を加え、重合部２及びその付近のビニールシート１を溶解させる（第二工程）。   Next, as shown in FIG. 1 (b), heat necessary for the vinyl sheet 1 to dissolve is applied to the vicinity of the overlapping portion of the two vinyl sheets 1 obtained in the first step, and the overlapping portion 2 And the vinyl sheet 1 of the vicinity is melt | dissolved (2nd process).

このとき、2枚のビニールシート１の重合部２のみを熱溶解するのではなく、その付近までも熱溶解させるのは、後述する加圧の際に均一にビニールシート１を圧延することができるようにするためである。なお、ここでいう重合部付近とは、該重合部２の幅にさらに夫々１〜５ｍｍ程度拡げた範囲をいう。   At this time, not only the superposed portion 2 of the two vinyl sheets 1 is melted hot, but also the vicinity thereof is melted so that the vinyl sheet 1 can be uniformly rolled during pressurization described later. It is for doing so. In addition, the vicinity of the superposition | polymerization part here means the range further expanded about 1-5 mm in the width of this superposition | polymerization part 2, respectively.

そしてこんどは、図１（ｃ）に示すように、前記第二工程によって熱で溶解した重合部付近に対し圧力を加え、ビニールシート１の溶解箇所を圧延する（第三工程）。該圧延は、例えば、図に示すようなプレス機１０によるプレスなどが考えられる。これにより、２枚のビニールシート１の重ね合わせた夫々の端辺が接合されて一体化し、一枚のビニールシート１化することとなる。   And this time, as shown in FIG.1 (c), pressure is applied with respect to the superposition | polymerization part melt | dissolved with the heat | fever by the said 2nd process, and the melt | dissolution location of the vinyl sheet 1 is rolled (3rd process). As the rolling, for example, pressing with a press 10 as shown in the figure can be considered. As a result, the overlapped ends of the two vinyl sheets 1 are joined and integrated into a single vinyl sheet 1.

最後に、前記第三工程によって圧力が加えられた前記重合部付近に対し、冷却を行なう（第四工程）。これにより、熱溶解により不安定化された接合部分の分子構造を再度安定化させ、完全に固定化することができる。   Finally, cooling is performed on the vicinity of the overlapping portion to which pressure is applied in the third step (fourth step). As a result, the molecular structure of the bonded portion destabilized by heat melting can be stabilized again and completely immobilized.

以上の各工程を経てることによって、図１（ｄ）に示すように、２枚のビニールシート１の接合部分において、耳は存在せず、肉厚も１枚のビニールシート１とほぼ同厚であって、強度的にも優れたビニールシート１を得ることができる。なお、かかる強度については、実験の結果、接合部分以外のビニールシート１の引張り強度に比して９０％以上の強度を保持しているという結果を得ることができた。   Through the above steps, as shown in FIG. 1 (d), there is no ear in the joint portion of the two vinyl sheets 1, and the wall thickness is almost the same as that of the single vinyl sheet 1. And the vinyl sheet 1 excellent also in intensity | strength can be obtained. In addition, about this intensity | strength, as a result of experiment, the result that the intensity | strength of 90% or more was hold | maintained compared with the tensile strength of the vinyl sheet 1 other than a junction part was able to be obtained.

次に、本発明にかかるビニールシート１の接合方法の第二の実施形態について説明する。
図２は、本発明にかかるビニールシート１の接合方法の第二の実施形態を示す概略説明図である。 Next, a second embodiment of the method for joining vinyl sheets 1 according to the present invention will be described.
FIG. 2 is a schematic explanatory view showing a second embodiment of the method for joining vinyl sheets 1 according to the present invention.

該第二の実施形態において、まず初めに行う第一工程については、上記第一の実施形態における第一工程と同様である（図２（ａ））。   In the second embodiment, the first step performed first is the same as the first step in the first embodiment (FIG. 2A).

前記第一工程により得られた2枚のビニールシート１の重合部付近に対し、図２（ｂ）及び図２（ｃ）に示すように、こんどは該ビニールシート１が溶解するために必要な熱を加えて重合部２及びその付近のビニールシート１を溶解させつつ圧力を加えることにより、ビニールシート１の溶解とその溶解箇所の圧延とを同時に行う（第二工程）。該圧延は、例えば、図に示すようなプレス機１０によるプレスなどが考えられる。これにより、２枚のビニールシート１の重ね合わせた夫々の端辺が接合され一体化され、一枚のビニールシート１化することとなる。   As shown in FIG. 2 (b) and FIG. 2 (c), this is necessary for the vinyl sheet 1 to dissolve in the vicinity of the overlapping portion of the two vinyl sheets 1 obtained in the first step. By applying pressure while applying heat to melt the polymerization portion 2 and the vinyl sheet 1 in the vicinity thereof, the melting of the vinyl sheet 1 and the rolling of the melted portion are simultaneously performed (second step). As the rolling, for example, pressing with a press 10 as shown in the figure can be considered. As a result, the overlapped ends of the two vinyl sheets 1 are joined and integrated into a single vinyl sheet 1.

なお、かかる第二工程については、特に限定するものではないが、例えば、ビニールシート１に対して圧力を加えるための加圧媒体に、熱を加えるための熱源（発熱機能）を備えさせることにより行う。   In addition, about this 2nd process, although it does not specifically limit, For example, by providing the pressurization medium for applying a pressure with respect to the vinyl sheet 1 with the heat source (heating function) for applying heat. Do.

また、ここでいう重合部付近とは、上記第一の実施形態と同様、該重合部２の幅にさらに夫々１〜５ｍｍ程度拡げた範囲をいう。   Moreover, the vicinity of the superposition | polymerization part here means the range further expanded about 1-5 mm in the width | variety of this superposition | polymerization part 2 like said 1st embodiment.

最後に、前記第二工程によって圧力が加えられた前記重合部付近に対し、冷却を行なう（第三工程）。これにより、熱溶解により不安定化された接合部分の分子構造を再度安定化させ、完全に固定化することができる。   Finally, cooling is performed on the vicinity of the overlapped portion to which pressure is applied in the second step (third step). As a result, the molecular structure of the bonded portion destabilized by heat melting can be stabilized again and completely immobilized.

以上の各工程を経てることによって、図２（ｄ）に示すように、２枚のビニールシート１の接合部分において、耳は存在せず、肉厚も１枚のビニールシート１とほぼ同厚であって、強度的にも優れたビニールシート１を得ることができる。また、2枚のビニールシート１の重合部付近に対し、熱溶解と加圧とを同時に行うことで、工程の省略化を図ることができる。なお、接合部分の強度については、第一の実施形態における実験結果と同様の結果を得ることができた。   Through the above steps, as shown in FIG. 2 (d), there is no ear at the joint portion of the two vinyl sheets 1, and the wall thickness is substantially the same as that of the single vinyl sheet 1. And the vinyl sheet 1 excellent also in intensity | strength can be obtained. Moreover, the process can be omitted by simultaneously performing heat melting and pressurization on the vicinity of the overlapping portion of the two vinyl sheets 1. In addition, about the intensity | strength of a junction part, the result similar to the experimental result in 1st embodiment was able to be obtained.

次に、本発明にかかるビニールシート１の接合方法の第三の実施形態について説明する。

このとき、該ビニールシート１１の幅は、１〜１０ｍｍの範囲内とすることが望ましい。１ｍｍ未満とすると、接合後の接合部分の強度が弱くなる恐れがあるとともに、１０ｍｍより幅を大きくした場合には、１〜１０ｍｍの範囲内で接合した場合と比して強度的に変化するものではなく、かえって後述する熱溶解や加圧、冷却のための時間・労力を増すこととなるからである。   At this time, the width of the vinyl sheet 11 is preferably within a range of 1 to 10 mm. If it is less than 1 mm, the strength of the joined portion after joining may be weakened, and when the width is made larger than 10 mm, the strength changes compared to the case of joining within the range of 1 to 10 mm. Instead, the time and labor for heat melting, pressurization, and cooling described later are increased.

It is for doing so. Here, the vicinity of the butt portion refers to a range further expanded by about 1 to 5 mm in the width of the separate vinyl sheet 11.

そしてこんどは、図３（ｃ）に示すように、前記第三工程によって熱で溶解した突合せ部付近及び別ビニールシート１１に対し圧力を加え、ビニールシート１の溶解箇所を圧延する（第四工程）。該圧延は、例えば、図に示すようなプレス機１０によるプレスなどが考えられる。これにより、２枚のビニールシート１の突合せた夫々の端辺が接合され一体化され、一枚のビニールシート１化することとなる。   And this time, as shown in FIG.3 (c), pressure is applied with respect to the butt | matching part melt | dissolved with the heat by the said 3rd process, and another vinyl sheet 11, and the melt | dissolution location of the vinyl sheet 1 is rolled (4th process). ). As the rolling, for example, pressing with a press 10 as shown in the figure can be considered.

最後に、前記第四工程によって圧力が加えられた前記突合せ部付近に対し、冷却を行なう（第五工程）。これにより、熱溶解により不安定化された接合部分の分子構造を再度安定化させ、完全に固定化することができる。   Finally, the vicinity of the butt portion to which pressure is applied in the fourth step is cooled (fifth step). As a result, the molecular structure of the bonded portion destabilized by heat melting can be stabilized again and completely immobilized.

以上の各工程を経てることによって、図３（ｄ）に示すように、２枚のビニールシート１の接合部分において、耳は存在せず、肉厚も１枚のビニールシート１とほぼ同厚であって、強度的にも優れたビニールシート１を得ることができる。なお、かかる強度については、実験の結果、接合部分以外のビニールシート１の引張り強度に比して９０％以上の強度を保持しているという結果を得ることができた。   Through the above steps, as shown in FIG. 3 (d), there is no ear at the joint portion of the two vinyl sheets 1, and the wall thickness is almost the same as that of the single vinyl sheet 1. And the vinyl sheet 1 excellent also in intensity | strength can be obtained. In addition, about this intensity | strength, as a result of experiment, the result that the intensity | strength of 90% or more was hold | maintained compared with the tensile strength of the vinyl sheet 1 other than a junction part was able to be obtained.

以上の各工程を経てることによって、図４（ｄ）に示すように、２枚のビニールシート１の接合部分において、耳は存在せず、肉厚も１枚のビニールシート１とほぼ同厚であって、強度的にも優れたビニールシート１を得ることができる。また、2枚のビニールシート１の突合せ部付近に対し、熱溶解と加圧とを同時に行うことで、工程の省略化を図ることができる。なお、接合部分の強度については、第三の実施形態における実験結果と同様の結果を得ることができた。   By going through the above steps, as shown in FIG. 4D, there is no ear at the joint portion of the two vinyl sheets 1, and the wall thickness is almost the same as that of the single vinyl sheet 1. And the vinyl sheet 1 excellent also in intensity | strength can be obtained. Moreover, the process can be omitted by simultaneously performing thermal melting and pressurization on the vicinity of the butt portion of the two vinyl sheets 1. In addition, about the intensity | strength of a junction part, the result similar to the experimental result in 3rd embodiment was able to be obtained.

以上のように、本発明にかかるビニールシート１の接合方法によれば、ビニール製のビニールシート、ビニールマット、ビニール床、ビニールテーブルクロス、フィルム、文具・雑貨からラミネート製品等の製造、加工または補修等について、広範な分野で利用可能である。   As mentioned above, according to the joining method of the vinyl sheet 1 concerning this invention, manufacture, processing, or repair of laminate products etc. from vinyl vinyl sheets, vinyl mats, vinyl floors, vinyl table cloths, films, stationery and miscellaneous goods Etc. can be used in a wide range of fields.
