【発明の詳細な説明】
【０００１】
【産業上の利用分野】本発明は、プラスチック製充填材
の超音波加工方法に係り、詳しくは冷却塔等の気液接触
塔内に充填する充填材や、浄化槽内に微生物保持体とし
て用いるプラスチック製充填材の超音波による加工方法
に関する。
【０００２】
【従来技術及びその課題】従来、充填材の加工方法は、
プラスチック製充填材シート（以下「シート」という）
同士間をスペーサ部で接着一体化し、組立てを行ってい
たが、接着手段としては有機溶剤型接着剤や二液型接着
剤を用いて接着を行っていた。
【０００３】しかしながら、上記有機溶剤型接着剤を用
いた場合には、溶剤の揮散による悪臭等の作業環境が問
題であり、上記二液型接着剤を用いた場合は、接着加工
作業が煩雑であるので、非効率的であり、かつ加工コス
トが高くつく等の問題があった。
【０００４】
【課題を解決するための手段】本発明は、上記課題を解
決するための超音波加工方法であって、その要旨は、多
数の突設部を有するプラスチック製充填材シートの該突
設部を、他のプラスチック製充填材シートに当接し、該
当接箇所を超音波発振機により、スポット溶着すること
を特徴とするプラスチック製充填材の超音波加工方法で
ある。
【０００５】以下、本発明を図面に基づき具体的に説明
する。図１は本発明で用いるシートを斜視図で示し、図
２は本発明でスポット溶着する状態を一部断面略図で示
す。
【０００６】図１に斜視図で示す如く、本発明で用いる
充填材を構成するシートＡは、肉厚０．３〜０．５mmの
プラスチックシートを真空成形法等により型成形して、
タテ、ヨコ略等間隔に突設部Ａ−１を形成し、必要に応
じ突設部Ａ−１を除く全面を波形に成形（不図示）した
ものである。
【０００７】上記シートＡの突設部Ａ−１を介して、他
のシートＡ面に溶着するには、図２に一部断面略図で示
す如く、超音波発振機１からコード１１により分岐連設
した溶着機本体２を、ホルダー３に複数取付け、該溶着
機本体２の振動子２１に付設した工具ホーン２２の先端
を、シートＡ、Ｂ同士の溶着部位に合わせ超音波発振に
より溶着するものである。
【０００８】シートＡ、Ｂ同士の溶着部位は、図示の如
くシートＡの突設部Ａ−１上にシートＢの下面を重ね合
わせ、該シートＢの上面側で突設部Ａ−１の当接部位上
に、溶着機本体２の工具ホーン２２の先端部２３を押し
当てて溶着するものである。
【０００９】本発明で用いる上記超音波発振機１は、発
振周波数が１５〜４０ＫＨｚの範囲であり、工具ホーン
２２の材質はチタン合金製或いはアルミニウム製で、そ
の先端部２３の面を滑り止めのローレット加工を施して
あり、振幅は１０〜４０μｍである。また溶着機本体２
に加える荷重（工具ホーン２２の先端にかかる荷重）は
４００〜９００ｇであり、超音波振動をシートに加える
時間は１〜２秒である。
【００１０】
【実施例】肉厚０．４mmのシートＡ、Ｂ同士を図２に示
す如く重ね合わせ、超音波発振機１の周波数を２８ＫＨ
ｚにセットし、溶着機本体２の振幅を２５μｍに調整
し、チタン合金製の工具ホーン２２の先端にローレット
加工を施した先端部２３を、シートＡの突設部Ａ−１上
のシートＢ上面に当て、６００ｇの荷重を加えて２秒間
押圧した結果、該当接箇所でシートＡ及びＢが確実に溶
着し強固に接合した。
【００１１】
【発明の効果】本発明は、上記構成よりなるので下記効
果を奏する。即ち、超音波エネルギーにより、シート同
士の溶着は複数箇所を同時に簡単かつ強固に接合できる
ので、従来のような接着剤使用に伴う作業環境の悪化
や、煩雑な接着加工作業を行うこと等から解放され、安
全で衛生的作業環境のもとで効率よく充填材の組立て接
合作業を行うことができる。
