Description
本発明は自動車用シートの製造方法、詳しくは発泡体製パッドの表面にホットメルト接着剤で表皮材を接着して形成する接着シートの製造方法に関する。 The present invention relates to a method for manufacturing an automobile sheet, and more particularly to a method for manufacturing an adhesive sheet formed by adhering a skin material to a surface of a foam pad with a hot melt adhesive.
従来の接着シートには、表皮材とパッドとの間に接着フィルム、ウェブネットなどからなるホットメルト型接着剤を介在させて、表皮材をパッドに加圧、加熱して、ホットメルト接着剤を溶融させて、表皮材をパッドに接着しているものがある（例えば特開平５-９２０８５号公報）。 In a conventional adhesive sheet, a hot melt adhesive made of an adhesive film, a web net or the like is interposed between the skin material and the pad, and the skin material is pressurized and heated to the pad, so that the hot melt adhesive is applied. Some have melted and bonded the skin material to the pad (for example, JP-A-5-92085).
以上のホットメルト型接着剤を使用したものは、蒸気、加熱型からの加熱などで加熱して接着剤を溶融し、その後、冷却する必要がある。 In the case of using the above hot-melt type adhesive, it is necessary to melt the adhesive by heating with steam, heating from a heating mold or the like, and then cool it.
そのため、従来は加熱と冷却のサイクルが必要となり、熱効率、生産効率が低下し、製造費用が増加する欠陥がある。 Therefore, conventionally, a cycle of heating and cooling is necessary, and there is a defect that thermal efficiency and production efficiency are lowered, and manufacturing costs are increased.
そこで、本発明は斯様な従来のホットメルト接着剤による接着シートの製造方法の不具合を除去することを目的とする。 Then, an object of this invention is to remove the malfunction of the manufacturing method of the adhesive sheet by such a conventional hot melt adhesive.
以上の目的を達成するための本発明に係る接着シートの製造方法は、発泡体製パッドの表面に、表皮材をホッドメルト接着剤で接着して形成する接着シートの製造方法であって、前記表皮材とパッドとの間に、ポリアミド系の熱可塑性合成樹脂製ホットメルト接着剤を配設して、表皮材をパッドの表面に、高周波又は超音波で接着することを特徴とする構成である。 The method for producing an adhesive sheet according to the present invention for achieving the above object is a method for producing an adhesive sheet, which is formed by adhering an outer skin material with a hod melt adhesive on the surface of a foamed pad. A hot melt adhesive made of a polyamide-based thermoplastic synthetic resin is disposed between the material and the pad, and the skin material is bonded to the surface of the pad with high frequency or ultrasonic waves.
従って、前記接着剤は高周波又は超音波に対して反応が迅速で、表皮材、パッドより温度上昇が早くなり、溶融が進む。 Accordingly, the adhesive reacts quickly with high frequency or ultrasonic waves, and the temperature rises faster than the skin material and the pad, and the melting proceeds.
また、局所的にホットメルト部分が溶融するため、冷却時間を短縮できる。 Further, since the hot melt portion is locally melted, the cooling time can be shortened.
本発明によれば、高周波又は超音波で接着するので、接着時における表皮材、パッドの熱変形による損傷を防止でき、また、冷却時間を短縮できる。従って、接着時の熱効率、生産効率が向上し、製造費用を低減可能となる。 According to the present invention, since bonding is performed with high frequency or ultrasonic waves, damage due to thermal deformation of the skin material and the pad during bonding can be prevented, and the cooling time can be shortened. Accordingly, the thermal efficiency and production efficiency at the time of bonding can be improved, and the manufacturing cost can be reduced.
以下、図面を参照しつつ本発明に係る接着シートの製造方法の好適な実施形態について説明する。 Hereinafter, a preferred embodiment of a method for producing an adhesive sheet according to the present invention will be described with reference to the drawings.
本発明はモールド加工したウレタンフォームなどの発泡体製のパッドに、ホットメル
ト接着剤で表皮材を接着して形成する接着シートであり、前記ホットメルト接着剤として、ナイロンなどのポリアミド系の熱可塑性合成樹脂製接着剤を使用し、表皮材をパッドに、高周波又は超音波によって接着することを特徴とする。
The present invention is an adhesive sheet formed by bonding a skin material with a hot melt adhesive to a foamed pad such as a molded urethane foam, and the hot melt adhesive is a polyamide-based thermoplastic such as nylon A synthetic resin adhesive is used, and the skin material is bonded to the pad by high frequency or ultrasonic waves.
以上の接着剤は、例えば、フィルム状、ウェブネット状のものを使用し、前記高周波又は超音波による接着は面状の接着剤の局所的にするのが好ましい。 The above adhesive is preferably in the form of a film or web net, for example, and the high-frequency or ultrasonic adhesion is preferably performed locally by a planar adhesive.
斯様に局所的に表皮材をパッドに接着することにより、加熱部分が少ないため、接着後の冷却時間を短縮できる。 In this way, by locally bonding the skin material to the pad, since there are few heated portions, the cooling time after bonding can be shortened.
図１において、図中１は袋状に縫製した表皮材、２はパッド、３はホットメルト接着剤(面状）を夫々示す。 In FIG. 1, reference numeral 1 denotes a skin material sewn in a bag shape, 2 denotes a pad, and 3 denotes a hot-melt adhesive (planar shape).
図面は超音波で、表皮材１をパッド２に接着する状態を示し、図中４は超音波溶着機の上電極、５は同下電極を夫々示す。この超音波溶着機の代わりに、高周波ウェルダーを使用して、表皮材１をパッド２の上面に前記接着材３で接着しても良い。 The drawing shows a state in which the skin material 1 is bonded to the pad 2 with ultrasonic waves, in which 4 indicates the upper electrode of the ultrasonic welding machine and 5 indicates the lower electrode. Instead of this ultrasonic welder, the skin material 1 may be bonded to the upper surface of the pad 2 with the adhesive 3 using a high-frequency welder.
なお、前記接着剤３はあらかじめ表皮材１の裏面側に一体に設けたものを使用してもよく、斯様に表皮材１側に接着剤３を一体に設けることにより、前記接着の作業性を向上し得る。 In addition, the adhesive 3 may be previously provided integrally on the back surface side of the skin material 1, and thus, by providing the adhesive 3 integrally on the skin material 1 side, the workability of the adhesion can be increased. Can improve.
以上のように、高周波又は超音波で表皮材１をパッド２にポリアミド系合成樹脂製接着剤３を使用して接着することにより、接着剤３の反応が早く、表皮材１及びパッド２に対して、温度上昇、溶融が迅速になる。 As described above, by bonding the skin material 1 to the pad 2 using the polyamide-based synthetic resin adhesive 3 with high frequency or ultrasonic waves, the reaction of the adhesive 3 is fast, and the skin material 1 and the pad 2 are bonded. The temperature rises and melts quickly.
その結果、表皮材１、パッド２に熱変形による損傷を防止できる。成形が可能となるし、また、接着後の冷却時間を大幅に短縮できる。従って、接着時の熱効率を向上し、生産効率が良好となり、製造原価を低減に得る。 As a result, the skin material 1 and the pad 2 can be prevented from being damaged by thermal deformation. Molding is possible, and the cooling time after bonding can be greatly shortened. Therefore, the thermal efficiency at the time of adhesion is improved, the production efficiency is improved, and the manufacturing cost is reduced.
