Claims (3)
- 耐圧チャンバーが熱盤を備える上箱とトレイを収容する下箱とから構成され、前記上箱と下箱に、それぞれ第1と第2真空ラインを介して、真空ポンプを連結し、前記真空ラインに、上下両箱それぞれに大気を取り入れる吸入弁を設けた、真空・ガス置換包装装置であって、
前記上箱に第1ガス供給ラインを、下箱に第2ガス供給ラインを接続すると共に、それぞれのガス供給ラインに圧力補償器付きの流量調整弁とガス開閉弁とを設置し、前記第1、第2両真空ラインにそれぞれガス圧検出用の圧力センサーを接続し、
前記真空ポンプの吸引力により上下両箱内の空気を排除したあと、前記第1、第2両ガス供給ラインから上下両箱内にガスを取り入れる際、カバーフイルムが上部の熱盤に向けて押し上がるような差圧が生ずるように、前記圧力センサーから発せられる信号により第1、第2両ガス供給ラインそれぞれのガス開閉弁を閉鎖した後、上箱の吸入弁を開放してその圧でもって前記熱盤で加熱したカバーフイルムを下箱内のトレイ上面に覆い被せる、
ことを特徴とする真空・ガス置換包装装置。 - 上箱に連結する第1真空ラインと、下箱に連結する第2真空ラインとの間に設けたバイパスラインに、第2真空ラインから第1真空ラインに向けて自由流となるチェック弁を配置する請求項1に記載の包装装置。
- 上箱に吸入弁から取り入れる大気圧に対する、カバーフイルム内の対向圧は、トレイに収容した被包装物の強度に合わせて設定できる請求項1に記載の包装装置。
