Abstract
【解決手段】加熱による融着性とレーザ光に対する透過性とを有した繊維シート11の片面にレーザ光吸収材層12を被覆し、さらにその表面を熱可塑性樹脂層13によりコーティングすることによりレーザ溶融接合用ベルト素材10を構成する。
【選択図】図1
Description
また、特許文献2(特開平4−157082号公報)には、レーザ光に対する透過性を有する薄肉厚シート等のレーザ溶接において、接合部に吸収率を高くした同一材質などの接合部の継手性能に影響を与えないレーザ光高吸収材を用いるレーザ溶接方法が記載されている。
樹脂繊維などの編み目を有したシートを重合させた接合部は、その合わせ目部分がレーザ光により溶融して接合されるが、この編み目を有する接合部分の微細凹凸空隙によって繊維間の融着が不均一となって、理想とする接合強度が得られない場合があった。
また、サンドイッチ状にレーザ光吸収材を介在させる従来の方法では、ベルトなどを構成する樹脂繊維に極めて近い位置において発熱作用が生ずるために、その樹脂繊維を過度に変質、劣化させるなどの虞れもあった。
さらに、レーザ光吸収材が被接合材の表面に露出して(浮き出て)黒い染みの状態となったり、接合部分の繊維がほつれたりして、製品としての見栄えを悪くさせる場合があり、ベルト製品の生産効率や歩留りが低下してコストアップに繋がるという問題があった。
また、ベルト素材の合わせ面をレーザ光により溶融して接合した場合であっても、編み目の微細凹凸空隙を有した繊維間の融着が均一となって、十分な接合強度が得られる。
さらに、レーザ光吸収材が被接合材の表面に露出して(浮き出て)黒い染みの状態を呈することなく、製品としての見栄えを悪くさせることもない、接合強度及び見栄えに優れたベルト製品を生産することが出来る。
これによって、ベルト素材を重ね合わせてレーザ光により接合する際の均一溶着を可能として接合強度やその外観に優れたベルト製品を効率的に製造できる。
このようにして、レーザ透過性のあるベルト素材及び、このベルト素材と相溶性があってレーザ吸収性のあるレーザ吸収材とを加圧しながら当接して、レーザ光を照射することによって重ね合わせた当接面を溶融し一体化させる。レーザとしては、半導体レーザやYAGレーザなどを経済性やビーム品質などの観点から特に好ましく用いることができる。
例えば、平織りは、経糸(たていと)と緯糸(よこいと)を交互に浮き沈みさせて織る最も単純な織物組織であり、丈夫で摩擦に強い。
綾織りは、タテ糸がヨコ糸の上を2本(3本)、ヨコ糸の下を1本、交差させて織られる織物であり、平織りよりもしなやかな風合いがあり、伸縮性に優れシワがよりにくいなどの利点がある。
しゅす織は、経糸(たていと)、緯糸(よこいと)五本以上から構成される織物組織であり、経・緯どちらかの糸の浮きが少なく、密度が高く地は厚いが斜文織よりも柔軟性や光沢に優れている。
これによって、服飾用ベルトや荷物吊用ベルトなどの帯状部材を製造する場合に、繊維シートを重ね合わせた合わせ目部分における溶融接合部分が均一にして所定の接合強度を保持させるととも、レーザ光吸収材が残存したり接合部分の繊維がほつれたりして製品としての見栄えを悪くさせるのを効果的に防止できる。
また、レーザ光吸収材の厚みが繊維シートの厚みの1/20より薄くなるにつれ、レーザ光吸収による発熱量が不足して効果的な溶着が困難になる。
逆に、レーザ光吸収材の厚みが1/10を超えて厚くなると、レーザ光吸収材が残存したり、不均一溶融によりベルト製品などの外観不良を生じたりする。
さらに、熱可塑性樹脂の厚みが繊維シートの厚みの1/20より薄くなると、溶融面をカバーするのに必要な樹脂量の不足を招いて外観不良が生じ易くなる。
逆に、熱可塑性樹脂の厚みが1/10を超えると、相対するレーザ光吸収材間の距離が大きくなり過ぎて所定強度の接合部を確保することが困難となるので好ましくない。
これによって、溶融接合部分となる2枚の繊維シート間を位置付けて密着させるとともに、レーザ照射により溶融させた繊維同士の接合状態を圧縮して密度を上げて強化することができるので、さらに接合強度に優れたベルト製品を効率的に得ることができる。
回転ローラは、XYステージ(コンベア)上などに搭載されて走行するレーザ溶融接合用ベルト素材の上方に配置されたレーザ発振器本体と、レーザ発振器本体から照射されるレーザビームの前後(移動するXYステージ上のベルト素材からみてレーザビームを挟んで前後)にそれぞれ設けられている。
このような回転ローラは、電動シリンダなどを介して重ね合わせた繊維シート間に所定加重、例えば約100〜200N(10〜20kgF)を付加するように構成できる。
図1は、実施例1のレーザ溶融接合用ベルト素材の一例を模式的に示す断面図である。図示するように、レーザ溶融接合用ベルト素材10は、その幅が約20mm、全体厚みが約1mmのテープ帯状などのものであって、例えば、ポリエステル繊維やポリプロピレン繊維などにより編織されて形成された繊維シート11と、その繊維シート11のいずれかの片面に設けられたレーザ光吸収材を形成させたレーザ光吸収材層12と、これら全体をカバーするようにコーティングされた熱可塑性樹脂層13とにより構成されている。
なお、平織り、綾織り、袋とじ織りなどにより編み上げられる繊維シート11は、その素材の種類や、厚み、繊維充填密度などを適宜選択して、その半導体レーザ発振器からの特定波長のレーザ光に対する透過度が所定範囲内になるように予め設定されるようにしている。
なお、本実施例ではローラ17は所定間隔を有した左右一対のローラからなり、図2に示すように、ローラ幅で平行する2条のレーザ光吸収材層が繊維シート11上に配置されるようにしている。
図示するように、製造されたレーザ溶融接合用ベルト素材10は、その端部同士又は異なるレーザ溶融接合用ベルト素材の端部を重ね合わせた後、そのレーザ光吸収材層のない裏面(図3(a)では上)側から、図示しないレーザ発振器を介して、所定出力、所定周波数の半導体レーザ光を照射される。
これにより、レーザ光吸収材層12がレーザ光を吸収して発熱して、レーザ溶融接合用ベルト素材10端部の当接部の材料を、相互に繊維間の隙間を埋めるように溶融させてレーザ溶着部12aが形成される。
そして、レーザ光の照射を止めることにより、当接部が冷却されるとともにレーザ溶着部12aが硬化して、接合強度と外観に優れた装飾用バンドや荷物吊り上げベルトを効率的に製造することを可能にしている。
なお、図3(c)は、レーザ溶着部を断続的に形成した場合のレーザ接合方法の平面説明図である。
この場合は、所定距離レーザ照射をした後、レーザ照射を停止したままベルト素材10を移動させて非溶着部を形成し、さらに所定距離レーザ照射をして溶着部を形成するという操作を繰り返す。
この場合は図3(c)に示すように、ステッチ状(破線状)に破線状レーザ溶着部12bが形成されて、レーザ溶着部での折り曲げができるという効果を奏する。
図4に示すように、本実施例のレーザ照射装置20は、XYステージ(コンベア)上などを走行するレーザ溶融接合用ベルト素材10の上方に配置されたレーザ発振器本体21と、レーザ発振器本体21から照射されるレーザビームの前後(図では左右であるが、移動するXYステージ上のベルト素材からみれば前後)にそれぞれ設けられた前側加圧ローラ22及び後側加圧ローラ23をレーザ発振器本体の下部に備え、レーザ発振器本体21をレーザ溶融接合用ベルト素材10側に向けて押圧するための電動シリンダ24とを備えている。なお、電動シリンダ24の上方は、レーザ照射装置20の図示しない機枠に固定されている。
そして、電動シリンダ24を駆動させることによって、レーザ発振器本体21の前側加圧ローラ22、後側加圧ローラ23を介して、レーザ溶融接合用ベルト素材10を150N(約15kgF)で加圧して、ベルト素材の長手方向6cm長さの溶融接合部分を形成した。
このようなレーザ照射装置とXYステージやコンベア装置などを組み合わせて、前後に配置した前側加圧ローラ22、後側加圧ローラ23で、重ね合わせたレーザ溶融接合用ベルト素材10同士を所定圧力で押さえながら、XYステージなどの移動により、設定された速度でベルト素材の移動方向に沿って線状にレーザ照射した。
本実施例で用いたレーザ発振器本体21は、ファイバーカップリング半導体レーザモジュール(Apollo Instrument社製:F100−808−6 100W:波長808nm)と、冷却チラー(オリオン社製:RSK−400SV−M)、電源部などから構成されており、ファイバー先端をアルミ製円筒内の集光レンズに接続した構造を有している。
そして、このベルト製品のレーザ溶融接合強度測定のN数を5として平均5.0kNを得た。なお、同素材を用いた従来方法で接合した縫製品の接合強度は、平均4.1kNであった。
以上のように、実施例2によるレーザ接合方法では、加圧ローラにより加圧しながらレーザ照射を行なったため、強度値のばらつきも少なく安定しており、縫製によるベルト製品に比較しても遜色ない強度測定の結果が得られることが明らかになった。
