【発明の属する技術分野】
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被検体調製方法及び被検体調製装置に関する。
【0002】
【従来の技術】
ジュースや牛乳などの液体食品などを充填した幾つかの紙製容器においては、所定の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押圧し横断方向の横シールにより密封し、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横シール帯域を含む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。
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し、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し、成形ローラ6によりチューブ状に成形し、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し、そのチューブ内に充填パイプ7から液体食品を充填し、このチューブを包装容器1個分に相当する長さ分だけ下方に送りながら、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し、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に切り離し、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。
【0003】
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。
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。
【0004】
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、例えば、横線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、溶融物が容器内部にはみ出ない横線シールを得ることが必要である。
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、直方体の形状の容器をマクラ形状にする。その枕状検査対象容器から被検体を調製する。
容器の品質検査に関して、被検体について、シール強度、ピンホールの有無、シール帯域の品質測定などを検査する。
【0005】
【発明が解決しようとする課題】
操作員によって定期的に抜き取られた容器の被検体の調製において、正確で規格に沿った容器開封が難しく、その開封に相当の時間を要し、簡易且つ正確な容器開封が被検体調製に切望されている。
容器被検体の調製における操作員の個人差により、容器の品質検査の結果にバラツキが生じ、検査の信頼性が低く、より正確且つ信頼性のある検査の必要がある。

In this embodiment, the pillow-shaped preform 13 is fixed and positioned at a predetermined position by the container fixing holder 44 including the fixing base 42 and the fixing arm 43.
The fixed pillow-shaped preform 13 is cut in the transverse direction on one side of the vessel wall 22 by a cutter 41 having a blade. The cutter 41 is driven by an air cylinder 45 to perform a translational reciprocating motion. A groove for the cutter 41 is formed in the fixed arm 43. The cutter 41 can be cut smoothly and accurately.
[0012]
In one embodiment of the present invention, the cut preform is pressed by the pressing means to extrude the filled food and is formed into a plate-shaped preform.
In FIG. 5 of the front view for explaining the operation of the pressing means in this embodiment and FIG. 6 showing the bottom face, side face and the like of the pressing plate, the preform 13 cut by the cutter 41 by the pressing plate 51 of the pressing means is shown. Then, the filled food is extruded and washed away by the washing nozzle 52 to form the plate-shaped preform 13a. The presser plate 51 is driven by an air cylinder 53 that moves up and down. The cleaning nozzles 52 are provided on both sides of the presser plate 51. After the cutting, the contents remaining in the container are washed with washing water from the washing nozzle 52 as the presser plate 51 moves downward.
FIG. 6 shows details of the presser plate 51. As shown in FIG. 6B, the presser plate 51 has a groove 62 formed on the bottom surface. The groove 62 prompts the discharge of the content liquid. Pressers 63 are provided on both sides. By the presser 63, both end portions of the preformed body 13 (location difficult to flatten) can be pressed down effectively.
[0013]
In one form of this invention, both sides parallel to the longitudinal sealing direction of the plate-shaped preform are cut off by the second cutting means.
Fig.7 (a) is a top view of the plate-shaped preform 13a which shows the plan part 71 by which both sides are cut off by the 2nd cutting means. A cutting line is formed in the transverse direction on the plate-shaped preform 13a by the first cutting means.
The plate-shaped preform 13a shown in FIG. 7A is cut off on both sides 71 by the second cutting means 75 and 76 shown in FIG. 7B. The second cutting means includes two pairs of upper blade 75 and lower blade 76.
By the operation of the second cutting, the container presser 77 descends from above and presses both sides of the plate-shaped preform 13a, and then the upper blade 75 of the second cutting means descends. Combined with the lower blade 76 of the second cutting means, the cut-off portion 71 is cut off. With this configuration, cutting can be reliably performed.
FIG. 8 is an operation diagram for explaining the second cutting step. The plate-shaped preform 13a is set before the second cutting operation (FIG. 8A). The plate-shaped preform 13a is somewhat swelled due to the restoring force. Next, the container presser 77 descends from above and presses both sides of the plate-shaped preform 13a (FIG. 8B). Finally, the upper blade 75 descends, and together with the lower blade 76, the cut-off portion 71 is cut off. (FIG. 8 (c)).
[0014]
In one embodiment of the present invention, the specimen is prepared by developing the cut container by the developing means.
FIG. 9 shows an operation diagram for explaining a development process in this embodiment. In this embodiment, the cut container 13a is developed by the air nozzle plate 91 and the vacuum pad 92, which are developing means, to prepare a subject. Compressed air from the air source 93 is blown from the plurality of nozzles to the air nozzle plate 91, and the upper vessel wall 22 of the plate-shaped preform 13a is lifted by the pressure. The vessel wall piece is lifted and further rotated by the vacuum pad 92 to form a substantially flat subject 80. With this configuration, it is possible to easily deploy without requiring a complicated mechanism.
[0015]
In one embodiment of the present invention, an example of the subject 80 being developed or prepared is shown in FIGS.
The prepared subject 80 has a substantially planar shape in the examination as shown in FIG.
The obtained specimen is subjected to examinations such as seal strength, presence / absence of pinholes, and quality measurement of the seal band.
