Description
【発明の属する技術分野】
本発明はシート状包装材料で作られた流動食品のパッケージをシールする超音波シール装置に関する。
【0002】
【従来の技術】
特に本発明は、それに限定されるわけではないが、シート状包装材料の連続充填されるチューブから作られるパッケージの成形およびシールを行うユニットに好ましく適用される。
【0003】
フルーツ・ジュース、低温殺菌またはUHT(超高温処理)ミルク、ワイン、トマト・ソースなどの多くの流動食品は、殺菌した包装材料で作られたパッケージにて販売されている。
【0004】
そのような典型的なパッケージは、テトラ・ブリック・アセプティック(登録商標)として知られた液体または流動食品用の平行六面体形状のパッケージであり、そのパッケージは積層した包装材料のウェブを折り曲げ且つシールして形成される。積層包装材料は、繊維質材料の層、例えばポリエチレンの熱密着性プラスチック材料で両面を被覆された紙を含み、またUHTミルクのような長期保存食品用の無菌パッケージの場合には、最終的にパッケージ内食品に接触されるパッケージ材料の面は、酸素バリヤ材料の層、例えばアルミニウムまたはエチレンビニルアルコール(EVOH)のシートも有し、これはさらに多数の熱密着性プラスチック材料の層で被覆される。
【0005】
知られているように、このようなパッケージは全自動包装機械で作られ、その機械ではウェブ給送される包装材料から連続チューブが形成され、その包装材料ウェブは包装機械自体において例えば過酸化水素溶液のような化学殺菌剤殺菌を付与することで殺菌され、殺菌剤は殺菌後に例えば加熱して蒸発させることで包装材料の表面から取り除かれ、またこのように殺菌された包装材料ウェブは閉じた無菌環境の中に保持され、折り曲げ且つ長手方向にシールされて垂直チューブを形成する。
【0006】
チューブは殺菌されたまたは無菌処理済みの食品を頂部から充填され、2組のジョーによって等間隔の横断部分にてグリップされる。さらに詳しくは、2組のジョーはチューブに対して周期的に連続して作用し、チューブの包装材料をシールし、またそれぞれの横断シール・バンドで互いに連結された枕形状パックが連続したストリップを形成する。
【0007】
枕形状パックはそれぞれのシール・バンドを切断することで分離され、またその後最終折り曲げステーションへ給送され、そこで最終的な平行六面体形状に機械的に折り曲げられる。
【0008】
バリヤ材料としてアルミニウムの層を有する無菌パッケージの場合、チューブの横断面部分は、通常、そのアルミニウムの層に損流を誘起させることで熱密着性プラスチック材料を局部的に溶融させてシールされる。
【0009】
特に、各組の一方のジョーは非導電性材料で作られた主本体と、主本体内の面座に収容された誘導子とを含み、他方のジョーは弾性材料、例えばゴムで作られた押圧パッドを含む。
【0010】
関係する1組のジョーがチューブのまわりをグリップしたときに誘導子が付勢され、プラスチック製のカバー材料をシールすることでチューブの横断面部分をシールする。
【0011】
アルミニウム層のないパッケージの場合、または他の導電性材料の場合、チューブの横断面部分は、通常、包装材料の内部を局部的に加熱するためにホット・プレートを使用してシールされる。
【0012】
さらに詳しくは、一方のジョーがホット・プレートを備え、他方のジョーは通常は1つ以上の弾性材料の押圧パッドを有する。このシール方法は「ホット・プレート」シールと称されるが、ホット・プレートと包装材料とを比較的長い時間接触させることが必要となる。
【0013】
包装材料の局部的な溶融を促進するために、またこのようにしてパッケージの生産量を増やすために、超音波シールの使用が増えており、これは一方のジョーが担持する超音周波数での機械的振動を発生する装置(以下に簡単に「超音波装置」と称する)と、反対側のジョーで担持され、堅い支持面として作用するアンビルとによって実施されるのであり、包装材料のチューブはその超音波装置およびアンビルの間にグリップされて2つの対面する材料壁を互いに接触且つ圧縮し、また超音波振動が材料を加熱して熱可塑性材料を溶融し、チューブ壁をシールする。
【0014】
さらに詳しくは、超音波装置は外側ケーシングと、ケーシングに収容された例えばEP−A−0615907に記載の形式の1つ以上の超音波振動発生装置と、一対の直角壁または折り曲げプレートとを含む。折り曲げプレートはケーシングの前部を閉じて前部開口を形成し、この開口を通して発生器は材料と協働する。折り曲げプレートは、シール作動時に形成される汚れ且つ溶融した熱可塑性材料に対する超音波振動発生器すなわちソノトロード(sonotrodes)の安全保護を果たし、ジョーと材料との接触状態を定め、このようにしてパッケージの幾何形状を定めることを補助する。
【0015】
しかしながら汚れ且つ溶融した熱可塑性材料は前部開口を通してジョーの内部に付着する傾向をさらに示し、したがって周期的な清浄作業が不可欠である。
【0016】
上述した形式の知られているジョーは幾つかの欠点を有す。
【0017】
第1に、ソノトロードの清浄作業は折り曲げプレートの完全な取り外しを必要とし、これは生産環境のもとでは実施できない。したがって、研究施設の状況のもとに熟練した者の助けを得て装置を完全に取り外すことが必要となる。
【0018】
例えば材料から突出するキャップのような予め取り付けられる開口装置を備えたパッケージを製造する場合、折り曲げプレートの1つは開口装置との干渉を防止するために、製造される特定形式のパッケージに応じて形状を定められねばならない。したがって、製造変更の場合には、全装置を取り外して交換しなければならない。
【0019】
【発明が解決しようとする課題】
本発明の目的は、既知の装置に典型的に存在する前述した欠点を解消するように設計された超音波シール装置を提供することである。
【0020】
【課題を解決するための手段】
本発明によれば請求項1に記載されたような超音波シール装置が提供される。
【0021】
添付図面を参照し、例を挙げて本発明の好ましい非制限的な実施例が説明される。
【0022】
【発明の実施の形態】
図1は、例えば低温殺菌またはUHT(超高温処理)ミルク、フルーツ・ジュース、ワインなどの流動食品2の、シールしたパッケージを生産する包装機械のための成形および横断シール・ユニットを全体的に示す。
【0023】
チューブ3は、熱密着性シート材料のウェブを長手方向に折り曲げてシールすることで知られたようにユニット1の上流で形成され、包装するために殺菌されたまたは無菌処理済みの食品2を頂部から連続的に充填され、そしてユニット1を通る垂直移送路Pに沿って下方へ充填方向に給送される。
【0024】
ユニット1は2つの成形およびシール組立体5(図1には1つだけ示される)を含み、この組立体は周期的且つ連続して包装材料のチューブ3と相互に作用してそのチューブを等間隔の横断シール・バンド6に沿ってグリップし、バンド6に沿って超音波シールを行って連続した枕形状のパック7を形成し、その後切断して枕形状のパックを切り離す。
【0025】
本発明を明確に理解するために必要であるとするだけで本明細書に記載した各組立体5は、チューブ3の反対両側に配置された実質的に2つのジョー8,9を含み、ジョーは本発明による超音波シール装置10と、アンビル11(図2)とをそれぞれ含む。
【0026】
アンビル11は、ジョー9に固定され且つ前部に互いに平行な水平上部リブ12と水平下部リブ13とを有するバーで実質的に形成されている。アンビル11はまたリブ12とリブ13との間に位置し且つナイフ15の座を形成する中央水平間隙14を含み、ナイフ15は横断シール・バンド6に沿ってチューブ3を切断するためにスライド可能に且つ周知の作動装置(図示せず)で制御されて収容される。
【0027】
装置10は2つのフランジ17でジョー8に固定されたケーシング16と、多数、例えば3つ、の並べられてケーシング16に収容された超音波振動発生器すなわちソノトロード18とを含む。
【0028】
さらに詳しくは、ソノトロード(図4)はEP−B−615907に記載された形式であることが好ましく、節面を定める中間フランジ24を含み、このフランジの一方の側には軸線方向にテーパー形のヘッド25がフランジから延在し、また反対側には2つの間隔を隔てた反作用錘26が延在し、反作用錘の間に圧電励起装置27が備えられている。
【0029】
ケーシング16はボックス形本体28を実質的に含み、本体は多数の凹部29が並べて備えられ、各々の凹部はそれぞれのソノトロード18の反作用錘および装置27を収容している。ケーシング16はまた、パッケージを形成するときにチューブ3と相互に作用する前部形成部分30と、前部開口31とを含み、この開口を通してそれぞれ並んで同一面をなすヘッド25の前部シール面32が外方へ向いている。
【0030】
シール作動が完了されてシール・バンド6を切断するときにナイフ15を受け入れるための中央スロット33によって面32は長手方向に2つのバンド32a,32bに分けられている。
【0031】
ソノトロード18はそれぞれの中間フランジ24によってケーシング16に固定され、中間フランジ24は本体28に形成されてそれぞれの凹部29を取り囲むそれぞれの環状凹部35に収容され、また形成部分30によって軸線方向の保持が行われ、中間フランジ24の残留振動の全てを吸収するために保持リング34を介在させて保持されることが好ましい。さまざまな個数の較正シム37(図4)が形成部分30と本体28との間に配置される。
【0032】
部分30は上側の直角アングル部材38と下側の直角アングル部材39で形成されており、これらの部材は、使用において包装材料のチューブ3の移送路Pに直角である本体28の対称水平中央面αに沿って組み合わされる。
【0033】
さらに詳しくは、直角アングル部材38,39はそれぞれ実質的に平坦なフランジ40,41を含み、これらのフランジはケーシング16の前部に固定され、また上述したようにソノトロード18を軸線方向に保持する。また直角アングル部材38,39はそれぞれの折り曲げプレート42,43を含み、それらのプレートはそれぞれのフランジ40,41から前方へ突出し、面αと平行且つヘッド25の横方向に延在し、またヘッド25を保護し、チューブ3と相互作用してパッケージを形成する。
【0034】
下側の部材39は一体部材であり、すなわち折り曲げプレート43がフランジ41と一体化されている。
【0035】
本発明によれば、上側の折り曲げプレート42は取り外し可能である。さらに詳しくは、上側の折り曲げプレート42は実質的に長方形且つ平坦であり、2つの横方向支持部材45と、上側のフランジ40から前方へ向かって突出し且つソノトロード18のヘッド25の間に位置された2つの実質的に梁状の中間支持部材46との上におかれる。
【0036】
製造されるパッケージが突出する開口装置47(図1)に嵌合されるならば、折り曲げプレート42の外面48は同じ形状の凹部49を同じ位置に含み、成形作動時に開口装置47を受け入れることが好ましい。
【0037】
実際の使用において、各成形組立体5のジョー8,9は知られているように周期的に作動され、各サイクルは装置10とアンビル11との間にチューブ3をグリップする段階と、ヘッド25の前部部分32のバンド32a,32bに沿ってシール作業を十分に実施できるようにするために移送路Pの部分に沿って接近した位置にジョー8,9を送る段階と、切断作業の段階と、チューブ3を解放するためにジョー8,9を開離させる段階と、ジョー8,9を次のサイクルに備えて上方の開いた位置へ戻すように送る段階とを含む。
【0038】
例えば汚れやシール作業時に形成された溶融した熱可塑性材料の痕跡を除去するために、ソノトロード18のヘッド25のクリーニングは、簡単に折り曲げプレート42を取り外すことで迅速且つ容易に行われる。折り曲げプレート42はまた、例えば凹部49のないプレート、または異なる形式の開口装置を受け入れるための別の形状の凹部を有するプレートと交換できる。
【0039】
既知の装置と相違して、プレート42はシール装置全体を取り外すことなく、また特にソノトロード18をケーシングから取り外すことなく、取り外しまたは交換することができる。さらに、生産環境においてこれを行うことができ、したがって保守および工具代えの時間、および製造を変更する場合の費用を減少でき、ならびに機械の停止による生産損失を減少できる。
【0040】
しかしながら特許請求の範囲に記載された範囲から逸脱せずに、本発明による装置10を変化できることは明白である。特に、下側の折り曲げプレート43を単独で、または一緒に取り除くことができる。またソノトロード18は何れの形式、形状のものが、また何れの個数も使用できる。
