Description

本発明は、ジュースや牛乳などの液体食品などを充填した紙製容器などの品質を検査するための検査方法に関する。 The present invention relates to an inspection method for inspecting the quality of a paper container filled with a liquid food such as juice or milk.

ジュースや牛乳などの液体食品などを充填した紙製容器においては、折り目線を有するウェブ状包装積層材料をチューブ状に成形し、チューブの縦線方向に縦シールし、チューブ状包装材料内に食品を充填し、所定間隔毎にチューブ状包装材料を横断方向に横シールし、横シール帯域中間で切断して枕状予備成形体を得、折り目線に沿って折り畳むことにより形成されたフラップを容器側壁及び容器底面にシールし、最終形状の容器を得る。 In paper containers filled with liquid foods such as juice and milk, web-shaped packaging laminate material with crease lines is formed into a tube shape, vertically sealed in the direction of the vertical line of the tube, and the food in the tube-shaped packaging material The tube-shaped packaging material is transversely sealed in the transverse direction at predetermined intervals, cut in the middle of the transverse sealing zone to obtain a pillow-shaped preform, and the flap formed by folding along the crease line is a container. Seal the side wall and the bottom of the container to obtain the final shaped container.

その紙製容器の充填包装機の一例の概要を、図１に示す。この例に示す充填機では、内外層に熱可塑性材料層を有しロール状に巻かれた包装材料ウェブ１を巻き出し、ローラにより充填機内を搬送する。ストリップテープ２をストリップテープアプリケータ３により、包装材料ウェブの一端に接合し、滅菌剤槽４内を包装材料ウェブが通過して滅菌し、エアーナイフ５により滅菌剤を除去する。成形ローラ６によりチューブ状ウェブを成形し、包装材料の両端部を重ねてオーバーラップを形成し、オーバーラップで縦線方向に縦シールエレメント８によりチューブ縦方向にシールする。そのチューブ内に充填パイプ７から液体食品を充填する。このチューブを下方に送りながら、シールジョー１０及び対向ジョー１１により挟持し、横断方向に横シールして２本の横シール帯域を形成する。同時に、枕状予備成形体１２に連続的に成形し、繋がった枕状予備成形体のシール帯域の中間をナイフなどにより切断して個々の枕状予備成形体１３を得る。ファイナルフォルダー１５において切り離された枕状予備成形体の上下のフラップを折り曲げて最終形態の包装充填容器１４に成形する。 An outline of an example of the paper container filling and packaging machine is shown in FIG. In the filling machine shown in this example, the packaging material web 1 having a thermoplastic material layer on the inner and outer layers and wound into a roll is unwound and conveyed inside the filling machine by a roller. The strip tape 2 is joined to one end of the packaging material web by the strip tape applicator 3, the packaging material web passes through the sterilant tank 4 and sterilized, and the sterilizing agent is removed by the air knife 5. A tubular web is formed by the forming roller 6, and both ends of the packaging material are overlapped to form an overlap, and the overlap is sealed in the vertical direction of the tube by the vertical seal element 8 in the vertical line direction. The tube is filled with liquid food from the filling pipe 7. While this tube is fed downward, it is sandwiched between the sealing jaw 10 and the opposing jaw 11 and laterally sealed in the transverse direction to form two lateral sealing zones. At the same time, the pillow-shaped preforms 12 are continuously molded, and the middle of the seal band of the connected pillow-shaped preforms is cut with a knife or the like to obtain individual pillow-shaped preforms 13. The upper and lower flaps of the pillow-shaped preform that has been cut off in the final folder 15 are folded and formed into a final package filling container 14.

枕状予備成形体１３が、ファイナルフォルダー１５で折り畳まれる態様を図２に示す。枕状予備成形体１３は、２本の横（横線）シール帯域２３及び縦シール帯域２６で密封され、折り目線によって区分された側壁２２、２２b及び２２ａを有する。（図２（ａ）参照）
図２（b）に示すように、折り目線に沿って、枕状予備成形体の本体部分が直方体形状に成形され、端部には、横シール帯域２３と、フラップ２４、２５とが器壁から直立するように形成される。横シール帯域２３は、底面２２ｂと頂面２２ａとから直立し、フラップ２４、２５は、稜辺２５ａ、２４ａを介して容器壁に一体的に連通する。
次いで、図２（c）に示すように、横シール帯域２３を折り畳んだ後、稜辺を中心にフラップを回転して、容器頂部側フラップ２４は、側壁２２に、容器底部側フラップ２５は、底面２２ｂに、折り込まれる。 A mode in which the pillow-shaped preform 13 is folded at the final folder 15 is shown in FIG. The pillow-shaped preform 13 is sealed with two horizontal (horizontal line) seal zones 23 and vertical seal zones 26, and has side walls 22, 22b and 22a separated by crease lines. (See Fig. 2 (a))
As shown in FIG. 2 (b), the body portion of the pillow-shaped preform is formed in a rectangular parallelepiped shape along the crease line, and the lateral seal band 23 and the flaps 24 and 25 are formed on the end portion of the instrument wall. It is formed to stand upright. The lateral seal zone 23 stands upright from the bottom surface 22b and the top surface 22a, and the flaps 24, 25 communicate integrally with the container wall via the ridges 25a, 24a.
Next, as shown in FIG. 2 (c), after folding the transverse seal zone 23, the flap is rotated around the ridge, the container top side flap 24 is on the side wall 22, and the container bottom side flap 25 is Folded into the bottom surface 22b.

図３に、直方体状液体食品充填紙製容器の外観斜視図を示す。その容器１４は、折り込まれた横シール帯域２３、容器壁２２及び２２ａ、頂壁２２ａから背面の器壁を経て底面に至る縦シール帯域２６を有し、稜辺２４ａを介して折り込まれたフラップ２４を備える。   In FIG. 3, the external appearance perspective view of a rectangular parallelepiped liquid food filling paper container is shown. The container 14 has a folded horizontal sealing zone 23, container walls 22 and 22a, a vertical sealing zone 26 extending from the top wall 22a through the back wall to the bottom, and is folded through a ridge 24a. 24.

前記シール帯域において、容器に収容された液体食品が漏れたり、外気に触れたりすることがないように、十分なシールが行われなければならない。しかし、横シールの温度及び圧力が適切でない場合、包装積層材料の溶融熱可塑性材料が、内容物が充填されている容器の内部にはみ出すことがある。その溶融物は、内容物の液体食品等と直接に接触し、急冷して脆くなり、はみ出した箇所から積層材料が破断する恐れがある。シールに際し、包装積層材料同士が十分に接着していなくてはならない。   In the sealing zone, sufficient sealing must be performed so that the liquid food contained in the container does not leak or come into contact with the outside air. However, if the temperature and pressure of the transverse seal are not appropriate, the molten thermoplastic material of the packaging laminate material may protrude into the container filled with the contents. The molten material comes into direct contact with the liquid food or the like of the contents, becomes rapidly fragile and becomes brittle, and the laminated material may be broken from the protruding portion. At the time of sealing, the packaging laminate materials must be sufficiently bonded together.

そこで、充填包装機で製品化された液体食品容器は、検査に際して、その機械の操作員によって定期的に抜き取り、抜き取られた容器について、容器の最終形状成形と実質的に逆の方法で、すなわち、充填包装機のファイナルフォルダーでフラップが折り畳まれた逆の方法で、フラップを器壁から引き剥がして、被検体を調製する。
縦シール／横シールの検査に関して、シール強度、ピンホールの有無などの他、シール帯域を破壊若しくは非破壊で、電気的若しくは目視で測定することによって検査する。
特開２００３−１９４６６２号公報 Therefore, liquid food containers that have been commercialized with a filling and packaging machine are periodically extracted by an operator of the machine at the time of inspection, and with respect to the extracted containers, the method is substantially opposite to the final shape of the container, that is, The specimen is prepared by peeling off the flap from the instrument wall by the reverse method in which the flap is folded in the final folder of the filling and packaging machine.
Regarding the inspection of the vertical seal / horizontal seal, in addition to seal strength, presence / absence of pinholes, etc., the seal zone is inspected by measuring it electrically or visually without breaking or non-destructing.

As shown in FIG. 1, the object of the quality inspection method of this embodiment is that a roll-shaped packaging material web 1 having a crease line is unwound, formed into a tube shape by a forming roller 6, and both ends of the packaging material are overlapped. An overlap is formed, and the overlap is longitudinally sealed by the vertical seal element 8 in the vertical line direction, the food is filled from the filling pipe 7 into the tube-shaped packaging material, and the tube has a length corresponding to one packaging container. While being fed only downward, it is sandwiched between the sealing jaw 10 and the opposing jaw 11 and laterally sealed in the transverse direction to form two lateral sealing zones, and the middle of the sealing zone of the connected pillow-shaped preform is formed with a knife or the like Cut into individual pillow-shaped preforms 13 and fold the upper and lower flaps of the pillow-shaped preforms separated in the final folder 15 to finish. A container obtained by molding the packaging filling container 14 of the state.

図４に横シール装置の詳細一部断面図を示す。この態様では、食品が充填されたチューブ状包装材料１が包装容器１個分に相当する長さ分だけ下方に送られながら、２対の成形フラップ４１により挟まれておおよその容器形状に成形され、２対のシールジョー１０及び対向ジョー１１により挟持し、横断方向に横シールして２本の横シール帯域を形成し、繋がった枕状予備成形体のシール帯域の中間をナイフ４２により切断して個々の枕状予備成形体１３に切り離す。
得られた容器は、図３に示すように、直方体状液体食品充填紙製容器１４である。容器１４は、折り込まれた横シール帯域２３、容器壁２２及び２２ａ、頂壁２２ａから背面の器壁を経て底面に至る縦シール帯域２６を有し、稜辺２４ａを介して折り込まれたフラップ２４を備える。 FIG. 4 shows a detailed partial cross-sectional view of the horizontal sealing device. In this embodiment, the tube-shaped packaging material 1 filled with food is formed into an approximate container shape by being sandwiched between two pairs of molded flaps 41 while being sent downward by a length corresponding to one packaging container. Two pairs of sealing jaws 10 and opposing jaws 11 are sandwiched and transversely sealed in the transverse direction to form two transverse sealing zones, and the middle of the sealing zone of the connected pillow-shaped preform is cut with a knife 42. To separate individual pillow-shaped preforms 13.
As shown in FIG. 3, the obtained container is a rectangular parallelepiped liquid food-filled paper container 14. The container 14 has a folded horizontal sealing zone 23, container walls 22 and 22a, a vertical sealing zone 26 extending from the top wall 22a through the back wall to the bottom surface, and a flap 24 folded through a ridge 24a. Is provided.

この発明の実施の形態において、上記容器は、前処理手段によって、図２に示す充填包装機のファイナルフォルダーでフラップが折り畳まれた容器の最終形状成形と実質的に逆の方法で、そのフラップが容器壁に一体的に連通する稜辺を中心に、容器壁にシールされているフラップが回転されてその器壁から引き剥がされ、枕状予備成形体の形状に戻される。 In the embodiment of the present invention, the above-described container is subjected to pre-processing means in a manner substantially opposite to the final shape forming of the container in which the flap is folded at the final folder of the filling and packaging machine shown in FIG. The flap sealed on the container wall is rotated around the edge that communicates integrally with the container wall, and is peeled off from the container wall to return to the shape of the pillow-shaped preform.

次いで、容器器壁を切断手段で全体的若しくは部分的に切断して充填された食品を取り出し、枕状予備成形体を板形状にする。図５に示すように、板形状予備成形体の横辺部を切り取り、片方器壁２２の中央を横断方向に切断する。調製手段で、切断された容器を実質的に平面状に若しくは所定の形状に展開する。図６に示すような被検体６１例を調製する。 Next, the container wall is cut entirely or partially by cutting means to take out the filled food, and the pillow-shaped preform is formed into a plate shape. As shown in FIG. 5, the lateral side portion of the plate-shaped preform is cut and the center of the one-sided container wall 22 is cut in the transverse direction. With the preparation means, the cut container is developed into a substantially flat shape or a predetermined shape. 61 specimens as shown in FIG. 6 are prepared.

この発明の実施の形態において、横シール帯域２３及び／又は縦シール帯域２６の被検査領域が予熱される。
図７に、ラインヒータ７１によって、被検体４１の横シール帯域２３を予熱する態様を示す。被検体４１の横シール帯域２３のシール幅に合わせて、ラインヒータ７１の焦点距離を調整する。ラインヒータ７１によって、被検体４１の横シール２３のシール面を均一に加熱処理する。 In the embodiment of the present invention, the region to be inspected of the horizontal seal zone 23 and / or the vertical seal zone 26 is preheated.
FIG. 7 shows a mode in which the horizontal seal zone 23 of the subject 41 is preheated by the line heater 71. The focal length of the line heater 71 is adjusted according to the seal width of the horizontal seal zone 23 of the subject 41. The line heater 71 uniformly heats the sealing surface of the horizontal seal 23 of the subject 41.

この発明の好ましい態様の品質検査方法では、予熱の熱量が調整される。
ラインヒータ７１の出力は、調整される。一例の基準例では、加熱直後に手で被検体のシール部分が破れること無く、また、シールされた部分の樹脂が支障無く剥離する。ラインヒータ７１の出力は、ワット数と加熱時間により調整する。 In the quality inspection method according to a preferred aspect of the present invention, the amount of preheating is adjusted.
The output of the line heater 71 is adjusted. In one reference example, the sealed portion of the subject is not broken by hand immediately after heating, and the resin in the sealed portion is peeled off without any trouble. The output of the line heater 71 is adjusted by the wattage and the heating time.

この発明の好ましい態様の品質検査方法では、予熱された被検査領域を、検出手段で測定する。
図８に示す態様の品質検査方法は、検出手段がＬＣＲメーター８１であり、測定パラメーターが静電容量（CP）及び／又は損失係数（D）である。個の態様に於いて、２枚の電極１と２（８１と８３）とは、横シール帯域２３の上に置き接触させて検査する。
被検体４１は、２枚の包装積層材料がシールされたものであり、図８に示す態様では、上から、最外プラスチック層、紙層、接着樹脂層、アルミ箔層、シール溶着樹脂層（最内プラスチック層）、アルミ箔層、接着樹脂層、紙層、最外プラスチック層の順序で積層されている。
２枚の電極（８１と８３）を置き、電圧を印加することによって、電極間に電位差が生じ、この導体の静電容量（CP）を測定できる。また、同様に損失係数（D）も測定できる。これらの測定値を用いてシールの品質を検査する。 In the quality inspection method according to a preferred aspect of the present invention, the preheated area to be inspected is measured by the detection means.
In the quality inspection method of the embodiment shown in FIG. 8, the detection means is the LCR meter 81, and the measurement parameter is the capacitance (CP) and / or the loss factor (D). In this embodiment, the two electrodes 1 and 2 (81 and 83) are placed on the lateral seal zone 23 and inspected.
The test object 41 is obtained by sealing two packaging laminate materials. In the embodiment shown in FIG. 8, from the top, the outermost plastic layer, paper layer, adhesive resin layer, aluminum foil layer, seal welding resin layer ( The innermost plastic layer), the aluminum foil layer, the adhesive resin layer, the paper layer, and the outermost plastic layer are laminated in this order.
By placing two electrodes (81 and 83) and applying a voltage, a potential difference occurs between the electrodes, and the capacitance (CP) of this conductor can be measured. Similarly, the loss factor (D) can be measured. These measurements are used to inspect the quality of the seal.

従来の品質検査方法では、予熱処理を行っていなかった。その方法では、シール良好とシール不良との識別が不明である。他方、この発明の好ましい態様の品質検査方法では、シール良好とシール不良との識別が明瞭に表れてくる。これは、被検体を予熱することにより、不良シール部のシール面に剥離現象が生じるためである。また、シール後の再結晶した状態が異なるために、誘電率（損失係数）が変わっている被検体を再加熱するために、電気的特性の違いが増幅さえたためであると考えられる。 In the conventional quality inspection method, pre-heat treatment is not performed. In that method, it is not clear whether the seal is good or bad. On the other hand, in the quality inspection method according to a preferred aspect of the present invention, the distinction between good seal and bad seal appears clearly. This is because a peeling phenomenon occurs on the seal surface of the defective seal portion by preheating the subject. Further, it is considered that the difference in electrical characteristics was amplified in order to reheat the specimen whose dielectric constant (loss factor) has changed because the recrystallized state after sealing is different.

この発明の別の態様の品質検査方法では、該被検査領域の予熱後、予熱された被検査領域を引き剥がして引き剥がし面を検出手段の表面検出装置で測定する。
図９にこの態様の品質検査方法を示す。図９に示すような被検体４１を、ローラと保持装置９４で保持する。保持した横シール帯域２３の両面を、一定熱量で予熱する予熱装置９１で加熱する。予熱後速やかに保持装置９４を矢印の方向の両側に駆動させ、横シール帯域２３を引き剥がす。この態様では、予熱装置９１を２台用いたが片方加熱のために１台であってもよい。
た横シール帯域２３の引き剥がし面を、画像検査装置、表面粗さ計などを装備する表面検出装置９３ａ、９３ｂで１種若しくは２種以上の測定パラメータを検出する。
２カ所の得られた測定パラメータを、中心軸に対して線対称に合成し、その合成データを基に判定装置９２によって。シール良否を判定する。この方法で、判定の基準値が標準化され、シールの良否を判定する明確な基準を可能にすることができる。 In the quality inspection method according to another aspect of the present invention, after preheating the inspected area, the preheated inspected area is peeled off, and the peeled surface is measured by the surface detection device of the detecting means.
FIG. 9 shows the quality inspection method of this aspect. A subject 41 as shown in FIG. 9 is held by a roller and a holding device 94. Both surfaces of the retained horizontal seal zone 23 are heated by a preheating device 91 that preheats with a constant amount of heat. Immediately after preheating, the holding device 94 is driven to both sides in the direction of the arrow, and the lateral seal zone 23 is peeled off. In this embodiment, two preheating devices 91 are used, but one may be used for one-side heating.
One or two or more types of measurement parameters are detected on the peeled surface of the lateral seal zone 23 by surface detection devices 93a and 93b equipped with an image inspection device, a surface roughness meter, and the like.
The two obtained measurement parameters are combined symmetrically with respect to the central axis, and the determination device 92 based on the combined data. Judge seal quality. In this way, the reference value for the determination is standardized, and a clear reference for determining the quality of the seal can be made possible.

なお、本発明は前記実施の形態に限定されるものではなく、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から排除するものではない。 In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

この発明の品質検査方法は、牛乳、ジュース、ミネラルウォーターなどの飲料、流動食品などの包装容器に利用することができる。 The quality inspection method of this invention can be used for beverages such as milk, juice, mineral water, and packaging containers for liquid foods.
