Thereby, it is formed so that the to-be-conveyed object 12 can be carried in into the opening part of the thermoplastic film 14 from the side of the belt conveyor 16. FIG.

包装物送出装置２０のベルトコンベア１６，２２の間であって、溶断溶着装置２４の上流側には、図２、図４に示すように、転向ローラ３８と水平方向に同じ面上に位置した開口部材４４が設けられている。開口部材４４の僅かに下流側であって包装物送出装置２０のベルトコンベア１６，２２の間には、口開部材４０と水平方向に同じ位置に設けられ、開口された熱可塑性フィルム１４の一対の開口縁部１４ａの上下に、熱可塑性フィルム１４の開口縁部１４ａを挟持する一対の短いフィルム繰り出しローラ４２が設けられている。また、熱可塑性フィルム１４の開口縁部１４ａとは反対側であって、ベルトコンベア１６，２２の一方の側方には、被包装物１２の移動をガイドするガイド板１７，２３が配置されている。   Between the belt conveyors 16 and 22 of the package delivery apparatus 20 and on the upstream side of the fusing and welding apparatus 24, as shown in FIGS. 2 and 4, it is positioned on the same surface in the horizontal direction as the turning roller 38. An opening member 44 is provided. A pair of the thermoplastic film 14 that is slightly downstream of the opening member 44 and between the belt conveyors 16 and 22 of the package delivery device 20 and provided at the same position in the horizontal direction as the opening member 40 and opened. A pair of short film feeding rollers 42 that sandwich the opening edge 14a of the thermoplastic film 14 are provided above and below the opening edge 14a. Also, guide plates 17 and 23 for guiding the movement of the article 12 to be packaged are arranged on the side opposite to the opening edge 14a of the thermoplastic film 14 and on one side of the belt conveyors 16 and 22. Yes.

熱可塑性フィルム１４は、転向ローラ３８から開口部材４０へ開口縁部１４ａが分かれて進行し、開口部材４４を経てフィルム繰り出しローラ４２により再び、開口縁部１４ａ部分のみが互いに閉じてフィルム引出装置４６に送られ、熱可塑性フィルム１４の二つ折りの内部には被収容物１２が収容される。このとき、開口部材４０，４４により経路が異なる二つ折りの各開口縁部１４ａは、転向ローラ３８からフィルム繰り出しローラ４２までの一対の開口縁部１４ａの移動距離が等しくなるように、転向ローラ３８、一対の開口部材４０，４４、及びフィルム繰り出しローラ４２の配置が設定され、これらの間で、熱可塑性フィルム１４の開口縁部１４ａは、平行四辺形を描くように進行する。これにより、この間の二つ折りされた対向する開口縁部１４ａ同士の長さが等しく、フィルム繰り出しローラ４２による一対の開口縁部１４ａの熱可塑性フィルム１４の送り量も等しいものである。   The thermoplastic film 14 advances from the turning roller 38 to the opening member 40 with the opening edge portion 14a divided, and the film drawing roller 42 passes through the opening member 44 again to close only the opening edge portion 14a. The object 12 is accommodated in the inside of the two-folded thermoplastic film 14. At this time, the bifurcated opening edge portions 14a whose paths are different depending on the opening members 40 and 44 are such that the moving distance of the pair of opening edge portions 14a from the turning roller 38 to the film feeding roller 42 is equal. The arrangement of the pair of opening members 40 and 44 and the film feeding roller 42 is set, and the opening edge portion 14a of the thermoplastic film 14 proceeds so as to draw a parallelogram between them. As a result, the lengths of the two oppositely opened opening edge portions 14a are equal to each other, and the feeding amount of the thermoplastic film 14 of the pair of opening edge portions 14a by the film feeding roller 42 is also equal.

溶断溶着装置２４には、上下方向に駆動するエアシリンダ等の駆動装置４５と上下方向の移動をガイドするガイド部材４７が設けられている。溶断溶着装置２４は、図示しない溶着部と溶断刃とを備え、熱可塑性フィルム１４の溶着と切断を行う。溶断刃の外側には、熱可塑性フィルム１４の移動を抑えるフィルム押さえが設けられ、溶断溶着時の熱可塑性フィルム１４の位置ずれを防止している。   The fusing device 24 is provided with a driving device 45 such as an air cylinder that drives in the vertical direction and a guide member 47 that guides the movement in the vertical direction. The fusing and welding apparatus 24 includes a welding portion and a fusing blade (not shown), and performs welding and cutting of the thermoplastic film 14. A film presser that suppresses the movement of the thermoplastic film 14 is provided on the outside of the fusing blade to prevent the thermoplastic film 14 from being displaced during fusing.

シール装置２６のベルトコンベア２２の側方と平行に位置した溶断溶着装置２４の外側には、一対のチェーンが噛み合って配置されたフィルム引出装置４６が、ベルトコンベア２２と平行に位置している。フィルム引出装置４６は、熱可塑性フィルム１４の二つ折りされた開口縁部１４ａを閉じた状態でフィルム送り方向に熱可塑性フィルム１４を引き出すものである。   On the outside of the fusing and welding device 24 positioned parallel to the side of the belt conveyor 22 of the sealing device 26, a film drawing device 46 in which a pair of chains are engaged with each other is positioned parallel to the belt conveyor 22. The film drawing device 46 draws the thermoplastic film 14 in the film feeding direction with the folded opening edge 14a of the thermoplastic film 14 closed.

次に、この実施形態の包装装置１０のフィルム送り及び包装動作について説明する。まず、包装装置１０の基端部側に設けられたフィルムロール１５から、二つ折りにされた可塑性フィルム１４が引き出され、フィルム送り装置１８を経て上方の張力調整部３２に送られる。さらに熱可塑性フィルム１４は、上方の転向ローラ３３から下方の転向ローラ３５を経て、フィルム転向部材３４に送られ、熱可塑性フィルム１４の送り方向が水平方向に９０°転向される。フィルム転向部材３４を経た可塑性フィルム１４は、包装装置１０の基端部の転向ローラ３６から垂直方向に上向きに送られ、包装装置１０の基端部上方の転向ローラ３８で水平方向に向けられる。   Next, the film feeding and packaging operation of the packaging apparatus 10 of this embodiment will be described. First, the plastic film 14 folded in half is drawn from the film roll 15 provided on the base end side of the packaging device 10, and sent to the upper tension adjusting unit 32 through the film feeding device 18. Further, the thermoplastic film 14 is sent from the upper turning roller 33 through the lower turning roller 35 to the film turning member 34, and the feeding direction of the thermoplastic film 14 is turned 90 ° in the horizontal direction. The plastic film 14 that has passed through the film turning member 34 is fed upward in the vertical direction from the turning roller 36 at the base end portion of the packaging device 10, and is directed in the horizontal direction by the turning roller 38 above the base end portion of the packaging device 10.

転向ローラ３８を経た熱可塑性フィルム１４は、二つ折りされた開口縁部１４ａが、開口部材４０により上下方向に所定の間隔に開口される。開口された二つ折りの熱可塑性フィルム１４の下側のフィルムは、ベルトコンベア１６に接して水平方向に位置し、対面する上方のフィルムは、ベルトコンベア１６と平行に位置するように、ベルトコンベア１６の下流側の端部上方に位置した開口部材４４に係合して、ベルトコンベア１６と平行に延出する。これにより、二つ折りされた熱可塑性フィルム１４の開口縁部１４ａにより、ベルトコンベア１６の側方に向かって開口部を形成する。   In the thermoplastic film 14 that has passed through the turning roller 38, the opening edge portion 14a folded in half is opened by the opening member 40 at a predetermined interval in the vertical direction. The lower film of the folded folded thermoplastic film 14 is in the horizontal direction in contact with the belt conveyor 16, and the upper film facing the belt conveyor 16 is positioned in parallel with the belt conveyor 16. It engages with the opening member 44 located above the downstream end of the belt and extends parallel to the belt conveyor 16. Thereby, an opening part is formed toward the side of the belt conveyor 16 by the opening edge part 14a of the thermoplastic film 14 folded in half.

ベルトコンベア１６の下流側に送られた熱可塑性フィルム１４は、フィルム繰り出しローラ４２間に両側の開口縁部１４ａが挟持され、下流側に送られ、さらに一対のフィルム引出装置４６間に熱可塑性フィルム１４の両側の開口縁部１４ａが挟持された状態で、一定の速度でフィルムの長手方向に送られる。   The thermoplastic film 14 sent to the downstream side of the belt conveyor 16 has the opening edge portions 14 a on both sides sandwiched between the film feeding rollers 42, sent to the downstream side, and further, the thermoplastic film between the pair of film drawing devices 46. The film is fed in the longitudinal direction of the film at a constant speed in a state where the opening edge portions 14a on both sides of 14 are sandwiched.

二つ折りの熱可塑性フィルム１４は、ベルトコンベア１６上で、開口縁部１４ａが開いた開口部を形成し、一旦停止した状態で被包装物搬入コンベア４３から被包装物１２が二つ折りの熱可塑性フィルム１４間に搬入可能となる。被包装物１２は、例えば食品容器であり、多数の容器が積み重ねられて２列で搬入され、被包装物搬入コンベア４３から二つ折りの熱可塑性フィルム１４内に送り込まれる。このとき、熱可塑性フィルム１４は、フィルムロール１５の状態から、開口部材４０，４４により開口されるまで、二つ折りの熱可塑性フィルム１４の内側は外部に露出せず、開口された後も二つ折り状態で内外面が反転されることなく、被包装物１２が一対の開口縁部１４ａ間から熱可塑性フィルム１４間に挿入される。   The two-fold thermoplastic film 14 forms an opening having an opening edge 14a on the belt conveyor 16, and the article to be packaged 12 is folded in two from the article carrying conveyor 43 in a state of being temporarily stopped. It becomes possible to carry in between the films 14. The packaged object 12 is, for example, a food container, and a large number of containers are stacked and carried in two rows, and are fed into the folded thermoplastic film 14 from the packaged article carrying-in conveyor 43. At this time, the thermoplastic film 14 is not exposed to the outside from the state of the film roll 15 until it is opened by the opening members 40 and 44, and is folded in half after being opened. The to-be-packaged item 12 is inserted between the pair of opening edge portions 14a between the thermoplastic films 14 without the inner and outer surfaces being reversed in the state.

被包装物１２が熱可塑性フィルム１４間に挿入されると、フィルム繰り出しローラ４２及びフィルム引出装置４６が作動し、熱可塑性フィルム１４を送り方向に引き出すとともに、ベルトコンベア１６，２２が作動し、被包装物１２を収容した熱可塑性フィルム１４が、ベルトコンベア１６上からベルトコンベア２２上へ移動する。この時、被包装物１２の進行方向先端側の熱可塑性フィルム１４の開口部は、前回の溶断溶着動作により熱溶着されて閉じられている。   When the article to be packaged 12 is inserted between the thermoplastic films 14, the film feeding roller 42 and the film drawing device 46 are operated, the thermoplastic film 14 is pulled out in the feeding direction, and the belt conveyors 16 and 22 are operated. The thermoplastic film 14 containing the package 12 moves from the belt conveyor 16 to the belt conveyor 22. At this time, the opening of the thermoplastic film 14 on the front end side in the traveling direction of the article 12 is thermally welded and closed by the previous fusing operation.

熱可塑性フィルム１４とともに被包装物１２がベルトコンベア２２上に送られ、熱可塑性フィルム１４の先端部が所定位置に達すると、一旦ベルトコンベア２２が停止し、駆動装置４５が作動し溶断溶着装置２４が下降して、熱可塑性フィルム１４の開口部を熱溶着して閉じる。溶断溶着装置２４は、Ｌ字型に形成され、ベルトコンベア１６，２２間で、熱可塑性フィルム１４を進行方向前後で分離し、前後の開口部を溶着する。熱可塑性フィルム１４の進行方向に平行な開口縁部１４ａは、ベルトコンベア２２に沿った溶断溶着装置２４の部分で、開口縁部１４ａの内側で溶断溶着される。この状態で、二つ折りの熱可塑性フィルム１４間に位置した被包装物１２を挟むように包装した熱可塑性フィルム１４の周囲３方の開口部が熱溶着により閉じられる。   When the article 12 to be packaged is sent onto the belt conveyor 22 together with the thermoplastic film 14 and the leading end of the thermoplastic film 14 reaches a predetermined position, the belt conveyor 22 is stopped once, the driving device 45 is activated, and the fusing and welding device 24 is operated. Is lowered, and the opening of the thermoplastic film 14 is thermally welded and closed. The fusing and welding device 24 is formed in an L shape, separates the thermoplastic film 14 between the belt conveyors 16 and 22 in the front and rear directions, and welds the front and rear openings. The opening edge part 14a parallel to the advancing direction of the thermoplastic film 14 is a part of the fusing and welding device 24 along the belt conveyor 22, and is fused and welded inside the opening edge part 14a. In this state, the three openings around the thermoplastic film 14 packaged so as to sandwich the article 12 to be packaged positioned between the two folded thermoplastic films 14 are closed by thermal welding.

溶断溶着装置２４のベルトコンベア２２の送り方向と平行な部分の溶断溶着装置２４よりも外側に位置した残余の熱可塑性フィルム１４は、フィルム引出装置４６により、引き出され、溶断溶着装置２４により被包装物の収容が終了したところで、図示しない巻き取り装置により巻き取られて、廃棄またはリサイクルに回される。   The remaining thermoplastic film 14 positioned outside the fusing and welding device 24 in a portion parallel to the feeding direction of the belt conveyor 22 of the fusing and welding device 24 is drawn out by the film drawing device 46 and wrapped by the fusing and welding device 24. When the storage of the object is completed, the product is wound up by a winding device (not shown) and sent for disposal or recycling.

以上の工程により、被包装物１２が熱可塑性フィルム１４により包まれ、周囲の開口部が溶断溶着装置２４により溶着されることにより被包装物１２の包装が完了する。   Through the above steps, the article to be packaged 12 is wrapped with the thermoplastic film 14, and the surrounding opening is welded by the fusing device 24, thereby completing the packaging of the article 12 to be packaged.

この実施形態の包装装置１０は、二つ折りの熱可塑性フィルム１４の表裏を反転することなく内側のフィルム面内に被包装物１２を収容し、開口部を溶着して包装しているので、被包装物１２に埃やウイルス等が付着する可能性がきわめて低く、清潔な包装が可能となる。これにより、食品容器や薬品容器、その他衛生用品や精密部品等、衛生状態やクリーン度が厳しく要求される被包装物の包装に利用可能である。しかも、二つ折りの熱可塑性フィルム１４を用いて開口部を形成しても、熱可塑性フィルム１４の開口した開口縁部１４ａ同士がずれたり閉じた状態で端部が一致しなかったりすることがなく、熱可塑性フィルム１４にしわや曲がりが生じず、包装状態も綺麗に仕上げることができる。   Since the packaging apparatus 10 of this embodiment accommodates the packaged article 12 in the inner film surface without inverting the front and back of the two-folded thermoplastic film 14 and welds and wraps the opening, The possibility of dust or viruses adhering to the package 12 is extremely low, and a clean packaging becomes possible. Accordingly, the present invention can be used for packaging food items such as food containers, chemical containers, other sanitary products, precision parts, and the like that require strict hygiene and cleanliness. Moreover, even if the opening is formed by using the two-folded thermoplastic film 14, the opening edge portions 14a of the thermoplastic film 14 are not shifted or closed so that the ends do not coincide with each other. The thermoplastic film 14 is not wrinkled or bent, and the packaging state can be finished beautifully.

なお、この発明の包装装置は、上記実施形態に限定されるものではなく、例えば、ベルトコンベアやフィルムの引出装置や繰出装置の構成や配置等は任意に設定可能なものである。   In addition, the packaging apparatus of this invention is not limited to the said embodiment, For example, the structure, arrangement | positioning, etc. of a belt conveyor, a film drawing apparatus, and a feeding apparatus can be set arbitrarily.
