Description

【考案の詳細な説明】 （産業上の利用分野） 本考案は、超音波の振動エネルギーを利用して連続的に
袋体端部の封を行う封袋装置に関するものである。
（従来の技術） 一般に、生理用品やポケットテッシュ等の生産ラインに
おいては、折り畳み等の加工を終えベルト上を搬送され
てくる半製品に対し機械による一連の動作で樹脂シート
による包装を行っている。
この樹脂シートによる包装工程においては、連続的に流
れてくる半製品を帯状の樹脂シートで包んだ後、各製品
ごとに樹脂シートの端を溶着し同時に切断して半製品を
個別に包装するようにしている。そして、このような包
装工程においては、従来、第５図および第６図に示すよ
うな封袋装置が用いられている。
この封袋装置は、半製品１を包み込んだ帯状の樹脂シー
ト２の流れの途中に互いに対向した一対のベルト３およ
び４が設けられ、このベルト３および４の間で樹脂シー
ト２の溶着と切断が行われるようになっている。ベルト
３とベルト４には所定ピッチで押し当て部材５が配設し
てあり、ベルト３あるいは４の何れか一方の押し当て部
材５の表面には、第６図に示すようにニクロム線６が埋
設してある。そしてベルト３および４の側方には電極７
が設置され、押し当て部材５が電極７の側方を通過する
際にニクロム線に接続された端子８が電極７と接触して
ニクロム線６が通電するようになっている。これによ
り、上下の押し当て部材５，５に挟まれた樹脂シート２
が電極７の側方を通過したところでニクロム線６の熱に
よる溶着と切断が行われ、半製品１が樹脂シート２によ
って個別包装される。
（考案が解決しようとする課題） しかしながら、このような従来の封袋装置においては、
ニクロム線６によって樹脂シート２の溶着と切断を行う
ようにしているため、ニクロム線６の切れによる装置全
体の頻繁な停止を余儀なくされるという問題があった。
さらにニクロム線６による溶着と切断においては、加熱
と冷却のための時間を要するため、樹脂シート２を挟み
込むべくベルト３および４の長さを十分に確保しなけれ
ばならず、必然的に装置が大型化するという問題もあっ
た。
本考案の目的は、樹脂シートから成る袋体に対してニク
ロム線を使用することなく連続的に溶着と切断が行える
ようにして、稼動効率の向上とコンパクト化が可能な封
袋装置を提供することである。
（課題を解決するための手段） 本考案は、上述した課題を解決するための手段として、
切断刃の両側に接着刃を有する接着切断刃を回転軸に設
ける一方、該回転軸の軸方向に沿って超音波発信装置に
連係された超音波付与部材を設け、前記接着切断刃の先
端部の回転軌道に前記超音波付与部材の頂部を臨ませる
ようにしたものである。
（作用） このような構成としたことにより、次のようにして樹脂
シートの溶着と切断が行われるようになる。
半製品を包み込んだ樹脂シートが連続的に送られてくる
と、まず、回転軸を中心に回転する接着切断刃の先端部
が超音波付与部材の頂部に接近し、樹脂シートが接着切
断刃と超音波付与部材で挟まれるようになる。この瞬間
に超音波付与部材に伝達される超音波の振動エネルギー
により、接着切断刃の一対の接着刃で樹脂シートの溶着
が行われ、その接着部間が切断刃で切断される。そし
て、回転軸の回転により接着切断刃が再び超音波付与部
材に接近したところで樹脂シートの次の溶着と切断が行
われる。
（実施例） 以下、本考案の一実施例を第１図ないし第４図に基づい
て詳細に説明する。
符号９は、図示しない駆動装置に連係された回転軸であ
り、この回転軸９の外周部には軸方向に添わせて接着切
断刃10が突設されている。接着切断刃10は、第３図に示
すように切断刃11の両側に接着刃12,12が配置された構
成となっている。この実施例の場合、具体的には接着切
断刃10の基材13の先端に切込みが入れられ、この切込み
によって二又に別れた基材13の両端部が接着刃12とさ
れ、両接着刃12,12の間に別部材の切断刃11が挟み込ま
れている。そして、接着刃12の端面は長手方向（回転軸
９の軸方向）に亙って凹凸状に形成され、切断刃11の端
面は平に形成されている。
また、回転軸９の上方には周知の超音波発信装置14が設
置されている。超音波発信装置14はブラケット15に支持
され、ブラケット15は超音波発信装置14の高さを微調整
するための昇降装置16に支持されている。超音波発信装
