Description
本発明の請求項3に記載のチューブ容器端部の超音波シール装置では、超音波振動子から工具ホーンに伝わる縦方向の超音波振動を横方向に変換する工具ホーンとして、十字型工具ホーンを用いることを特徴としている。工具ホーンとして十字型工具ホーンを用いると、例えば十字型工具ホーンの4つの先端の側面の表裏に押圧部を8つ形成可能である。そのため、工具ホーン先端の側面の合計8箇所の押圧部をそれぞれチューブ容器端部に順次対向させて取り付けることにより、1つのホーンの工具寿命を8倍に長寿命化し
て使用することができる。
図1に、本発明の第一の実施の形態にかかるチューブ容器端部の超音波シール装置(以下、「超音波シール装置」と略称する)の概略側面図を示す。本発明の第一の実施の形態にかかる超音波シール装置は、L字型断面をしたハウジング1の柱部分に、同じくL字型断面をしたスライダー2が紙面の上下方向(Y矢印方向)に図示しないエアーシリンダーで往復運動自在に取り付けられている。スライダー2には超音波振動するブースターホーン14が取り付けられ、ブースターホーン14の上端には超音波振動子3が、下端には工具ホーン5がそれぞれネジSで取り付けられている。工具ホーン5は、概ね十字型をしていて、十字の交差部分である中心部には奥行方向に貫通孔5cがあいている。
(式4) δ4=(1/3)F1×L2 3/EI
=(1/3)F1×(L1×2)3/EI
=(1/3)F1×(8×L1 3)/EI
=8×{(1/3)F1×L1 3/EI}
=8×δ1
(式5) δ1=1/8×δ4
図8に、本発明の第二の実施の形態にかかる超音波シール装置の要部側面図を示す。本発明の第二の実施の形態にかかる超音波シール装置は、本発明の第一の実施の形態にかかる超音波シール装置の図1と類似しているが、チューブ容器8を直立させ、チューブ容器8のキャップ9側を下に、チューブ容器端部8aを上して、工具ホーン5を図中のM矢印のように動かして、アンビル6と工具ホーン5でチューブ容器端部8aを紙面の水平方向に挟持するようにした点が異なる。溶着強度等の溶着性能自体は、第一の実施形態と同じであるが、チューブ容器8がキャップ9側を下にして直立しているため、実際の生産工程でチューブ容器の取り扱いが容易となる利点がある。
図9に、本発明の第三の実施の形態にかかる超音波シール装置の要部側面図を示す。本発明の第三の実施の形態にかかる超音波シール装置は、図8に示した本発明の第二の実施の形態にかかる超音波シール装置と構成は似ているが、工具ホーン5の先端のたわみ量を勘案して、チューブ容器端部8aを押圧する先端の押圧面を超音波振動方向に対して斜めに形成した点に特徴がある。溶着条件として、チューブ容器端部8aの押圧力が大きく、工具ホーン5の先端のたわみ量が大きい場合に、予め押圧面を斜めにしておくことにより、実際にチューブ容器端部8aをアンビル6と工具ホーン5で挟持した時に、チューブ容器端部8aの押圧力が均一となり、所定の溶着力が所定幅の領域にわたって得られるという利点がある。
図10に、本発明の第四の実施の形態にかかる超音波シール装置の要部側面図を示す。本発明の第四の実施の形態にかかる超音波シール装置は、本発明の第一の実施の形態にかかる超音波シール装置の工具ホーン5の水平方向の2つの先端部5h、5hの下面に、それぞれアンビル6、6を配置して、それぞれの工具ホーン5の先端下面と各アンビル6でチューブ容器端部8a、8aを挟持して、一つの工具ホーン5を超音波振動させることにより、同時に2つのチューブ容器端部8aを溶着するようにしたものである。工具ホーン5は左右対称の2つの位置でチューブ容器端部を押圧するので、超音波シール装置のスライダー2の負荷は左右にバランスが取れて上下動動作がスムーズである。これにより、一度に2つのチューブ容器端部を溶着するので生産性が2倍に向上するという利点がある。
上記第一から第四の実施の形態では、工具ホーンの超音波振動の振動方向を、縦方向から横方向に90度変換する特徴ある形状として「たわみ」を小さくした本発明の実施形態を説明した。本発明の第五の実施の形態は、上記工具ホーンを支持する構造を改良して「たわみ」を更に小さくしている。
