【発明の詳細な説明】 本発明は容器の封緘装置に関するもので従来合成樹脂、
ガラス、紙等からなる容器の口部を封緘する為にはアル
ミ箔等の金属箔やその他封緘に適した薄膜の接着面に熱
可塑性樹脂を塗布した封緘用薄膜を容器の口部に冠装し
、電気抵抗によって加熱されたいわゆるシールゴテを押
しあて熱可塑性樹脂を溶融させ容器の口部に接着させる
装置が用いられている、しかし乍らこの装置においては
加熱に要する時間が長く、間歇的に封緘作業か行われる
為連続封緘作業が困難であった。
本発明は上述の如き従来の判緘装置を改良し連続高速封
緘作業を可能にする装置を提供しようとするものである
。
以下本発明の実施例を図面によって詳細に説明する。
第１図、第２図における１は容器搬送用ベルトコンベア
ーで、４は前記容器搬送用ベルトコンベアー１の上方に
ベルトコンベアー１と同期平行移動するように金属体２
例えば複数筒の鋼片、アルミ片、銅片等を耐熱弾性材３
例えはテフロン等のベルト状皮膜でサンドウイチしてな
る加熱用押えベルトである。
５は加熱用押えベルト４の金属体２が磁気結合するよう
に加熱用押えベルト４の内側に近接配置した高周波誘導
加熱コイルである。
６は合成樹脂、ガラス、紙等からなる容器で、７は容器
の口部に冠装した封緘用薄膜で例えはアルミ箔等の金属
箔の単体又は複合体、その他封緘に適した薄膜等の接着
面に熱可塑性樹脂を塗布したものである。
以上の構成よりなる本発明の装置において連続移動する
容器搬送用ベルトコンベアー１上を封緘用薄膜７を冠装
した容器６が順次搬入され容器６が加熱用押えベルト４
の位置に達すると封緘用薄膜７を冠装した容器６は加熱
用押えベルト４によって押圧されその状態で順次搬送さ
れ高周波誘導加熱コイル５に近接する。
一方図示しない高周波発振機と接続されている高周波誘
導加熱コイル５には高周波電流が供給されているので容
器６を押圧しながら近接移動する加熱用押えベルト４の
金属体２は高周波誘導加熱コイル５と磁気結合し金属体
２が誘導加熱されるので加熱用押えベルトも加熱される
。
従って加熱用押えベルト４によって押圧されながら搬送
される容器６に冠装されている封緘用薄膜７に熱が伝導
し、接着面に塗布されている熱可塑性樹脂が溶融し容器
６の口部に接着し封緘が行われる。
加熱中押えベルト４及び封緘された容器６は高周波誘導
加熱コイル５の磁界から離れ、除々に冷却しながら容器
搬送用ベルト１と同期平行移動し、容器６は加熱用押え
ベルト４の押圧から解放されベルトコンベア１によって
完全に封緘された容器６は搬出される。
実施例では封緘用薄膜７として接着面に熱可塑性樹脂を
塗布したものを示したが本発明の装置によれはこれに限
定されるものでなく封緘用薄膜自体加熱によって接着性
を有するものを用いることができる。
以」−のように本発明の装置によれば加熱用押えベルト
４を構成している金属体２が高周波誘導加熱コイル５に
よって迅速にかつ均一に誘導加熱され加熱用押えベルト
４自体が加熱体として作用するので容器６の口部を封緘
用薄膜７をもった封緘する作業が能率よく連続的に行う
ことができる。
