Description

【考案の詳細な説明】
【０００１】
【産業上の利用分野】
本考案は食品等を対象とした自動包装機におけるフイルム袋の熱シール装置の 改良に係る。
【０００２】
【従来の技術】
図３は一般的なフイルム袋の熱シール方法を示すものであつて、内部に充填物 を収納したフイルム袋３が別途順次搬送されて来ると、架台９に装備された相互 に和反する方向へ移動されるものとなる１対の駆動軸８ａ、８ｂを作動させ、内 部にヒータ２ａ、２ｂを内蔵した１対の熱板１ａ、１ｂでフイルム袋３の上部開 口縁を両側端から一時的に挾圧することにより熱シールするようになつている。 図４はこのときの詳細説明図であつて、１対の熱板のうち片方の熱板１ａの挾 圧部には平坦な押圧面を有する突起体１ｃが形成され、その表面はテフロン膜４ によって被覆されてなり、他方の熱板１ｂの挾圧部にはシリコンゴム等の緩衝材 ５が装着されてなる。
【０００３】 従って、フイルム袋３は挾圧部の突起体１ｃの押圧面によつて局部的に強圧さ れ、テフロン膜４及び緩衝材５を介して熱シールされるようになつている。
【０００４】
【考案が解決しようとする課題】
上記の如き熱シール装置に於いて、今内部にうどん汁など高温（９０°〜９５ °Ｃ）の液体を収納したフイルム袋３の開口部を熱シールするさいには、内部の 液体から発生する湯気が付着した状態で熱シールすることになるが、上記熱板１ ａの突起体１ｃの押圧面が或る巾の平坦面ｍ（普通３〜５ｍｍ）を有するため、 シール面３ａに水滴６が封じ込められて分散して残留し、透明シール袋の場合に は濁つたようになり、またアルミ袋の場合には水ぶくれになるなどして見栄えが 悪く、商品価値が下り、粘着強度の低下にもつながる等の問題があつた。
【０００５】
【課題を解決するための手段】
本考案は上記問題点を解決せんとするものであつて、その特徴とするところは 熱板の挾圧部の片方に断面形状が曲面状Ｐをなす突起体１ｃを形成したことを特 徴とする。
【０００６】
【作用】
熱板の挾圧部に断面形状が曲面状Ｐをなす突起体１ｃを形成したので、フイル ム袋の開口部を熱シールするさいシール面に付着している水滴が突起体１ｃの押 圧動作によつて効果的に外方へ押出されて排除され、残留しないものとなる。
【０００７】
【実施例】
本考案の実施例を図１及び図２によつて説明する。図１に示す如く１対の熱板 １ａ、１ｂには夫々れヒータ２ａ、２ｂが内蔵され、図示しない１対の駆動軸（ 図３の８ａ、８ｂ）の作動により開閉させて給送されて来たフイルム袋３の開口 部を、その両側面外方から一時的に挾圧して熱シールするようになす。 このさい１対の熱板のうち片方の熱板１ａの挾圧部にはその断面形状が円弧状 、半円状、楕円状などの曲面状Ｐに形成された突起体１ｃを形成し、テフロン膜 を被覆形成する。 これに対し、他方の熱板１ｂの挾圧部にはシリコンゴムなどの緩衝材５を装着 させることは従来通りである。
【０００８】 今、内部にうどん汁など高温の液体が収納されるフイルム袋の熱シールについ て説明する。 シール前フイルム袋３の開口部付近には収納された高温液体から発生する湯気 が水滴となつて付着している。この状態で熱板１ａ、１ｂを閉塞すると袋開口部 はその両側面外方から挾まれる突起体１ｃによつて押圧されるが、このとき突起 体１ｃが曲面状ｐに形成されていることから先づ突起体１ｃの最先端がフイルム 袋面に接したのち緩衝材５、テフロン膜４等の緩衝効果によつて徐々に接触面が 外方に広がり、それと共にシール面に付着した水滴も外方へ押し出されるから、 結局図２に示す如く水滴の残留しない綺麗なシール面が形成されるものとなる。
【０００９】
【考案の効果】
以上の通り、本考案の熱シール装置は熱板の挾圧部に断面形状が曲面状ｐをな す突起体１ｃを形成したので熱シールのさい、シール面に付着した水滴が曲面状 突起体の作用によつて排除されるものとなり、水滴の残留しない綺麗なシール面 が形成されるものとなる。また、粘着強度も高く、シール性が良くなるなどの効 果がある。
