Description
、効率の良い溶着を行うことができるものの、以下の点でさらに解決すべき課題もあった。
さらに、本発明の課題は、斜めシールの発生や包材の無駄等も無くすことができる超音波シール装置を提供することにある。
また、スライド部材を用いることで、エアーシリンダやカム機構をメンテナンス等を考慮した好適な位置に配置することが可能になる。
さらに、前記カム部材は、孔の壁面がカム面にされた長孔を有するカム板からなり、前記スライド部材のカム板側の端部には、前記長孔内に位置してカム面に接触する転がりガイドが設けられているので、カム板の往復移動をスライド部材の往復移動に確実かつ高精度に変換することができる。
さらにまた、ホーン又はアンビルの移動量をカム機構の設計によって微調整できるようにするために、前記長孔は上下に延ばされるととともに斜めに傾斜され、かつ前記スライド部材の移動量を大きくするために設けた中央傾斜部と、スライド部材の移動量を小さくするために設けた上部傾斜部及び下部傾斜部とを一対有するように湾曲された形状とした。
そして、溶着対象部の溶着部分が変化する過程においては、当該溶着部分が無理に加圧されることはない。なぜなら、エアーシリンダの場合、気体の圧縮に伴う反発力を利用しているため、エネルギーの蓄積が容易であり、油圧シリンダに比べて充分な緩衝機能を発揮させることができるからである。しかも、前記した具体的構成(中央傾斜部、上部傾斜部及び下部傾斜部)からなるカム面を有するカム機構を介してその力を伝達する構成を採用しているため、ホーン及びアンビルに必要な相対変位(スライド部材のスライド量)は高精度に調整することができる。その結果、溶着面部分が溶融した分だけ溶着部を加圧して薄くするために必要な力の制御も極めて容易になる。即ち、互いの溶着面が溶けてゆく
速さに比例してアンビルとホーンを互いに接近させることができる。これにより、溶着対象部の溶着を確実にして疑似溶着を無くすことが可能になる。
このホーン1はスライド部材11Aに連結された後述する第1駆動装置Aにより、アンビル2側に向かって進退自在に設けられている。
