  • the packaging container is formed by sealing a predetermined portion of the packaging material by a method such as heat sealing or ultrasonic sealing.
  • a method such as heat sealing or ultrasonic sealing.
  • the packaging material is made into a tube shape, sealed in the vertical direction by a vertical sealing device, and then filled with liquid food in the tubular packaging material.
  • FIG. 1 is a perspective view showing a main part of a conventional filling machine.
  • the web-shaped packaging material 11 is set in a delivery unit (not shown) of the filling machine in the state of the reel 31.
  • the packaging material 11 from which the feeding force is also fed is intermittently conveyed by a feeding device (not shown) as a conveying means, and the strip tape 18 is applied to the edge of the packaging material 11 by the strip tape application device 17. Worn.
  • the packaging material 11 is intensively sent to the heating device 19 and heated, and the strip tape 18 is attached to the heated packaging material 11.
  • a hot air type heating device an induction heating type heating device, or the like can be used as the heating device 19.
  • the temperature of the packaging material 11 can be adjusted by setting the temperature of the hot air.

  • Patent Document 1 Japanese Patent Laid-Open No. 2001-18909 Disclosure of the invention
  • the conventional heating device 19 there are variations in the environmental temperature, the initial temperature before heating the packaging material 11, and the structure of the packaging material 11 (for example, moisture content, paper thickness, aluminum foil thickness, etc.). When this occurs, the temperature when the packaging material 11 is heated by the heating device 19 will vary. As a result, the strip tape 18 cannot be stably adhered to the packaging material 11, the sealing performance of the packaging container is lowered, and the quality of the packaging container is degraded.

発明を実施するための最良の形態
[0019] 以下、本発明の実施の形態について図面を参照しながら詳細に説明する。
[0020] 図 2は本発明の実施の形態における充填機の概念図である。
[0021] 図に示されるように、ウェブ状の包材 11は、リール 31の状態でカセット 32に収容さ れ、該カセット 32を介して充填機の図示されない送出部にセットされる。前記包材 11 は、紙基材、及び該紙基材の両面に榭脂としてのポリエチレン榭脂のフィルムが被覆 された可撓性の積層体力 成り、必要に応じて紙基材とフィルムとの間にアルミニウム 箔、ガスノ リャ性榭脂等力も成るバリヤ層が形成され、包装容器 33の表面に相当す る部分にあら力じめ外装用の印刷が施される。
[0022] 前記送出部力 繰り出された包材 11は、搬送手段としての図示されない送り装置 によって間欠的に搬送され、ベンディングローラ rl、ダンパローラ r2、ベンディング口 ラ r3、 r4を経て用紙テンショナ 35に送られた後、ベンディングローラ r5に送られる。そ の間に、包材 11の一方の縁部にストリップテープ貼着装置 37によってストリップテー プ 38が貼着される。
[0023] 続いて、包材 11は、用紙テンショナ 43及びベンディングローラ r6、 r7を経て殺菌槽 61に送られ、該殺菌槽 61において過酸化水素等の殺菌液によって殺菌される。な お、 62は殺菌槽 61の底部トレイである。
[0024] その後、包材 11は、カレンダローラ r8を介してェャナイフ 45に送られ、該ェャナイ フ 45によって乾燥させられた後、ベンディングローラ r9、クリースローラ rlO及びベン ディングローラ r 11を介してアツパ成形リング 48に送られる。そして、該アツパ成形リン グ 48、可動成形リング 49、分割成形リング 50及びロワ成形リング 51によって徐々に 変形させられてチューブ状にされ、その間に、包材 11は縦シール装置 55によって縦 方向にシールされ、包材 11の縦シール部分の合せ面及びストリップテープ 38を密着 させ、充填パイプ 52を介して供給された流動性食品がチューブ状の包材 11内に充 填される。
[0025] そして、前記流動性食品が充填された前記包材 11は押圧案内装置 64に送られる 。該押圧案内装置 64は、包材 11の内側に配設された第 1の回転体としての図示され ないプレツシャローラ、及び包材 11の外側に配設された第 2の回転体としてのカウン タローラ 66を備え、包材 11の搬送に伴って、前記縦シール部分の合せ面及びストリ ップテープ 38を強く挟む。
[0026] 続いて、包材 11は、チューブ支持ローラ rl2によって案内され、シール'切断部 pi に送られ、該シール'切断部 piにおいて、図示されないシール'切断装置によって挟 まれ、所定の間隔ごとに横方向にシールされ、切断されて一定量の流動性食品を収 容する枕状の原型容器 23が形成される。そして、該原型容器 23は、最終成形搬送 装置 58に送られ、該最終成形搬送装置 58よって搬送されるとともに、所定の形状に 成形され、包装容器 33が完成する。
[0027] ところで、ストリップテープ貼着装置 37によってストリップテープ 38を包材 11に貼着 するに当たり、包材 11は図示されない加熱装置によって加熱される。そして、包材 11 の温度は図示されない加熱制御装置によって制御される。
[0028] 図 3は本発明の実施の形態における加熱制御装置の概念図である。
[0029] 図において、 11は矢印 A方向に搬送される包材、 37は包材 11にストリップテープ 3 8を貼着するためのストリップテープ貼着装置、 71は、包材 11の搬送方向におけるス トリップテープ貼着装置 37より上流側に配設され、包材 11を加熱する加熱装置であ る。前記ストリップテープ貼着装置 37は、包材 11を挟んで回転自在に配設され、スト リップテープ 38を供給する供給ローラ 37a及び圧着ローラ 37bを備える。また、前記 加熱装置 71は、ホットエア式の加熱装置力 成り、包材 11と対向させてホットエアノ ズル 72を備える。該ホットエアノズル 72は、包材 11と対向する面に複数の穴が形成 され、加熱源としての高温空気発生源 77と接続され、該高温空気発生源 77から供 給された加熱媒体としての高温空気を、前記各穴を介して包材 11の表面に吹き付け る。また、前記包材 11の搬送方向における加熱装置 71より下流側に、該加熱装置 7 1と隣接させて、包材 11の温度を検出する第 1の温度検出部としての温度センサ 75 が配設され、検出された温度 tlは制御部 74に送られる。前記温度センサ 75は赤外 線放射温度計によって構成される。そして、ホットエアノズル 72内には、高温空気の 温度を検出する第 2の温度検出部としての、かつ、媒体温度検出部としての温度セン サ 73が配設され、
検出された温度 t2は制御部 74に送られる。
[0030] ところで、本実施の形態においては、環境温度、包材 11の加熱前における初期温 度、包材 11の構造 (例えば、水分率、紙厚、アルミ箔厚等）にばらつきが発生しても、 加熱装置 71によって包材 11を加熱したときの温度にばらつきが発生することがない ように、制御部 74によって包材 11の温度が制御される。そのために、制御部 74に設 定器 76が接続され、包材 11の温度 tlが、設定器 76によって設定された第 1の目標 となる温度を表す目標温度 tslになるようにフィードバック制御が行われる。すなわち 、制御部 74の図示されない温度制御処理手段は、温度制御処理を行い、温度セン サ 75によって検出された温度 tl及び目標温度 tslを読み込み、温度 tlと目標温度 t s 1との偏差 Δ tlを算出し、該偏差 Δ tlに基づ 、て前記高温空気発生源 77を駆動 する。その結果、包材 11の温度を目標温度 tslにすることができる。
[0031] このように、前記温度 tl及び目標温度 tslに基づ 、て高温空気発生源 77が駆動さ れるので、環境温度、包材 11の加熱前における初期温度、包材 11の構造にばらつ きが発生しても、加熱装置 71によって包材 11を加熱したときの温度にばらつきが発 生することがなくなる。したがって、ストリップテープ 38を包材 11に安定させて貼着す ることができ、包装容器 33のシール性を向上させ、包装容器 33の品質を向上させる ことができる。
[0032] ところで、充填機を停止させたときに、加熱装置 71を停止させると、ホットエアノズル 72に高温空気が供給されなくなり、充填機の運転を再開したときに、ホットエアノズル 72の温度の立上りが悪くなり、充填機の運転効率が低下してしまう。
[0033] そこで、本実施の形態においては、充填機の停止中においても、加熱装置 71が駆 動され、ホットエアノズル 72に高温空気が供給されるようになっている。そして、その 間、前記制御部 74によって高温空気の温度 t2が制御される。そのために、前記高温 空気の温度 t2が、設定器 76によって設定された第 2の目標となる温度を表す目標温 度 ts2になるようにフィードバック制御が行われる。すなわち、制御部 74の図示されな ぃ予熱温度制御処理手段は、予熱温度制御処理を行い、温度センサ 73によって検 出された温度 t2及び目標温度 ts2を読み込み、温度 t2と目標温度 ts2との偏差 Δ t2 を算出し、該偏差 A t2に基づいて前記高温空気発生源 77を駆動する。その結果、 高温空気の温度 t2を目標温度 ts2にすることができるので、ホットエアノズル 72の温 度の立上りが良くなり、充填機の運転効率を向上させることができる。
[0034] 本実施の形態においては、加熱装置 71として、ホットエア式の加熱装置が使用さ れるようになっているが、ホットエア式の加熱装置に代えて誘導加熱式の加熱装置を 使用することちできる。
[0035] なお、本発明は前記実施の形態に限定されるものではなぐ本発明の趣旨に基づ いて種々変形させることが可能であり、それらを本発明の範囲力 排除するものでは ない。
産業上の利用可能性
