[0007] 本発明の他の充填機においては、さらに、前記第 1の回転体は、永久磁石を備え たプレツシャローラである。そして、前記第 2の回転体はカウンタローラである。また、 前記回転検出信号発生部は、永久磁石の移動に伴って回転検出信号を発生させる
[0008] 本発明の更に他の充填機においては、さらに、前記監視処理手段は、プレツシャロ ーラが正常に回転させられているときの回転検出信号を基準信号とし、その後、所定 のタイミングで回転検出信号を読み込み、該回転検出信号と基準信号とを比較して、 プレツシャローラが正常に回転させられていない場合、プレツシャローラの回転異常 を検出する。

[0015] 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。
[0016] 図 1は本発明の実施の形態における充填機の概念図である。
[0017] 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 1 1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- ゥム箔、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。
[0018] 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、ダンバローラ r2等を経て、ストリツ プテープ貼着装置 40に送られ、該ストリップテープ貼着装置 40によって包材 11の一 方の縁部に沿ってストリップテープ 34が貼着される。続いて、包材 11は、ベンディン グローラ 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は、パンチ装置 36によって穴開加工が施されてパンチ穴が 形成され、インナテープ貼着装置 37によってインナテープ 38が貼着されて前記パン チ穴が内側力 シールされ、プルタブ貼着装置 41によってプルタブ 42が貼着され てパンチ穴が外側からシールされる。
[0019] 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。
[0020] その後、包材 11は、カレンダローラ r8を介してエアナイフ 45に送られ、該エアナイ 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、前記包材 11は、 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の形状にされ、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、充填パイプ 52を介して供給された流動性 食品が包材 11内に充填される。 [0021] そして、前記流動性食品が充填された前記包材 11は、包材 11の搬送方向におけ る縦シール装置 55より下流側に配設された押圧案内装置 64に送られる。該押圧案 内装置 64は、搬送される包材 11の縦シール部分の合せ面側に配設された第 1の回 転体としての図示されな 、プレツシャローラ、及び包材 11を挟んで前記プレツシャロ ーラと対向させて配設された第 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、縦シール部分の合せ面及びストリップテープ 34の貼着面を密着さ せるようになっている。
[0022] 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によって搬送されるとともに 、所定の形状に成形され、一定量の流動性食品を収容する包装容器 33が完成する
[0023] 次に、前記押圧案内装置 64について詳細に説明する。
[0024] 図 2は本発明の実施の形態における押圧案内装置の監視方法を示す概念図、図 3 は本発明の実施の形態におけるプレツシャローラの取付状態を示す図、図 4は本発 明の実施の形態における押圧案内装置の概略図である。
[0025] 図において、 11は包材、 52は支持部材として機能する充填パイプ、 65は、縦方向 にシールされた直後の包材 11の縦シール部分の合せ面側にぉ 、て、支持機構部 6 8によって支持され、縦シール部分を押さえる第 1の回転体としてのプレツシヤローラ である。
前記支持機構部 68は、充填パイプ 52の所定の箇所に取り付けられたブラケット 69、 該ブラケット 69から下方に延在させて配設された付勢部材としてのテンションロッド 7 1、該テンションロッド 71の中間部分において充填パイプ 52に取り付けられ、テンショ ンロッド 71を支持する支持部材 72、前記テンションロッド 71の先端（図 4において下 端）に取り付けられ、プレツシャローラ 65を矢印 A方向に回転自在に支持する回転支 持部 73等を備え、前記テンションロッド 71は、所定の付勢力で包材 11を径方向外方 に向けて押す。 [0026] また、 66は、前記包材 11を挟んで、前記プレツシャローラ 65と対向させて配設され 、プレツシャローラ 65による押圧力を受ける第 2の回転体としてのカウンタローラであ り、該カウンタローラ 66は、支持部 75によって充填機のフレームに対して矢印 B方向 に回転自在に支持される。
[0027] したがって、包材 11が矢印 C方向に搬送されるのに伴って、前記プレツシャローラ 6 5及びカウンタローラ 66が包材 11及びストリップテープ 34 (図 1)を挟んだ状態で回 転させられ、縦シール部分の合せ面及びストリップテープ 34の貼着面を密着させる。
[0028] ところで、縦シール装置 55によって包材 11がシールされる際に、包材 11、ストリツ プテープ 34等が加熱されるので、包材 11、ストリップテープ 34等の最内層を構成す るポリエチレン榭脂等の樹脂がプレツシャローラ 65の外周面に貼り付くことがあり、そ の場合、プレツシャローラ 65に抵抗が加わり、該プレツシャローラ 65の回転速度が低 くなる。
[0029] そして、その状態を放置しておくと、包材 11、ストリップテープ 34等の内周面が損傷 を受けたり、貼り付いた榭脂が包材 11内に落下したりして、流動性食品の品質が低 下してしまうことがある。
[0030] そこで、前記プレツシャローラ 65内の外周面の近傍、又は外周面に臨ませて、円周 方向の複数の箇所に永久磁石 81が、 N極及び S極を交互に外側に向けて配設され る。また、前記カウンタローラ 66を中空体で形成し、カウンタローラ 66内の包材 11と 対向する側の所定の箇所に、前記プレツシャローラ 65と近接させて、検出部としての 、かつ、回転検出信号発生部としての磁気センサ 82を配設し、前記充填機のフレー ムに固定する。前記磁気センサ 82は、例えば、ホール素子等によって形成される。そ して、前記プレツシャローラ 65が回転させられるのに伴って、磁気センサ 82と対向す る箇所に各永久磁石 81の N極及び S極が移動し、前記磁気センサ 82は、周期的に 変化する回転検出信号を発生させて出力し、制御部 83に送る。
[0031] ところで、プレツシャローラ 65に抵抗が加わらず、プレツシャローラ 65が正常に回転 させられている場合には、包材 11が搬送されるのに伴って、包材 11の搬送速度とプ レツシャローラ 65の周速度とは等しぐ前記回転検出信号は、一定の周期でピーク値 を発生させる。これに対して、プレツシャローラ 65に抵抗が加わり、プレツシャローラ 6 5が正常に回転させられなくなると、包材 11が搬送されるのに伴って、包材 11の搬送 速度とプレツシャローラ 65の周速度とは等しくならず、前記ピーク値が発生する周期 が変動する。
[0032] そこで、前記制御部 83の図示されな 、監視処理手段は、監視処理を行!、、プレツ シャローラ 65が正常に回転させられているときの回転検出信号を基準信号として記 録装置 84に記録し、その後、所定のタイミングで回転検出信号を読み込み、該回転 検出信号と基準信号とを比較して、プレツシャローラ 65が正常に回転させられている かどうかを判断する。
[0033] そして、該プレツシャローラ 65が正常に回転させられていない場合、前記監視処理 手段は、プレツシャローラ 65の回転異常を検出し、制御部 83の図示されない報知処 理手段は、報知処理を行い、アラーム信号を発生させて警報装置 85に送り、操作者 に異常の発生を報知する。
[0034] 本実施の形態においては、プレツシャローラ 65に永久磁石 81が配設され、磁気セ ンサ 82は、プレツシャローラ 65が回転し、永久磁石 81が移動するのに伴って回転検 出信号を発生させるようになつている力 カウンタローラ 66に永久磁石を配設し、所 定の位置に磁気センサを配設し、カウンタローラ 66が回転し、永久磁石が移動する のに伴って磁気センサによって回転検出信号を発生させるようにすることができる。さ らに、プレツシャローラ 65及びカウンタローラ 66の両方に永久磁石を配設することも 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
[0036] 包装容器製造装置に利用することができる。
