Description

本発明は、深絞り型包装機および深絞り型包装システムに関するものである。 The present invention relates to a deep drawing type packaging machine and a deep drawing type packaging system.

深絞り型包装体は、図１に示すように、相対的に肉厚で硬質のフィルム（下側フィルム）を成型して形成される凹状のポケット部２ａを有する容器本体２と、そのポケット部２ａ内に被包装物を収納した状態でその容器本体２の開口部を閉塞する相対的に肉薄で軟質のフィルム（上側フィルム３）とを備えた構成を採る。容器本体２は、ポケット部２ａの周囲に外側に突出するフランジ部２ｂを有し、上側フィルム３はそのフランジ部２ｂの全周に渡って熱シールされることで無端状のシール部４が形成され、ポケット部２ａの内部を密封するようになっている。 As shown in FIG. 1, the deep-drawn package has a container body 2 having a concave pocket portion 2a formed by molding a relatively thick and hard film (lower film), and the pocket portion. The structure provided with the relatively thin and soft film (upper film 3) which obstruct | occludes the opening part of the container main body 2 in the state which accommodated the to-be-packaged object in 2a. The container body 2 has a flange portion 2b protruding outward around the pocket portion 2a, and the upper film 3 is heat-sealed over the entire circumference of the flange portion 2b, thereby forming an endless seal portion 4. Thus, the inside of the pocket portion 2a is sealed.

容器本体２のフランジ部２ａの全面に上側フィルム３を熱シールし、フランジ部２ｂと上側フィルム３の外周縁を一致させた場合、フランジ部２ｂから上側フィルム３を引きはがすことが非常に困難となる。そこで、係る構成の深絞り型包装体の開封を容易にするためにたとえば、特許文献１や特許文献２のように、上側フィルム３の外周縁の一部をフランジ部２ｂと未接着にし、摘み部分Ｔを形成したものがある。この構造からなる深絞り型包装体では、その摘み部分Ｔを指で挟み持った状態で上側フィルム３をフランジ部２ｂから引き離す方向に引っ張ることで、簡単に当該上側フィルム３をフランジ部２ｂから離脱させて開封することができる。そして、特許文献１，２に開示された発明では、さらに摘み部分Ｔの形状に特徴を持たせている。つまり、これらの特許文献の目的とするところは、開封の際の摘み部分Ｔがシール時に熱溶着してしまうのを防止し、かつ上下のフィルムの間に間隙を形成することにより、上下のフィルム（摘み部分）を持って容易に開封を行うことができるようにしたものである。
実公昭３７−２１９８７特開２０００−２３６３９ When the upper film 3 is heat-sealed over the entire surface of the flange portion 2a of the container body 2 and the outer peripheral edges of the flange portion 2b and the upper film 3 are matched, it is very difficult to peel the upper film 3 from the flange portion 2b. Become. Therefore, in order to facilitate the opening of the deep-drawn package having such a structure, for example, as in Patent Document 1 and Patent Document 2, a part of the outer peripheral edge of the upper film 3 is unbonded to the flange portion 2b, and is picked. Some have formed part T. In the deep-drawn package having this structure, the upper film 3 can be easily detached from the flange portion 2b by pulling the upper film 3 away from the flange portion 2b while holding the grip portion T with a finger. Can be opened. In the inventions disclosed in Patent Documents 1 and 2, the shape of the knob portion T is further characterized. That is, the purpose of these patent documents is to prevent the gripping portion T at the time of opening from being thermally welded at the time of sealing, and to form a gap between the upper and lower films, thereby forming the upper and lower films. It can be easily opened with a (pick portion).

しかしながら、上述した特許文献１，２に開示したように、摘み部分の形状を工夫をしたとしても、以下のような問題が発生する。すなわち、この種の深絞り型包装体は、下側フィルムにポケット部を形成し、そのポケット部内に被包装物となる内容物を入れ、上側フィルムで蓋をし、下側フィルムのポケット部の未形成領域と、それに対向する上側フィルムのフィルム部位を上下から挟み込むと共に加熱することでポケット部の周囲を溶着シールを行いポケット部内を密封する。このとき、摘み部分を構成する領域は、加圧しない（シール装置のシーラのシール面の一部に凹部を設ける）ことで未シール状態とする。この後、上記の融着シールした部位の所定位置、つまり、前後のポケット部の間であってフィルムの搬送方向と直交する方向に横カットし、次いで、左右のポケット部（横方向に並ぶポケット部）の間をフィルムの搬送方向に沿って縦カットすることにより、個々の深絞り型包装体が製造される。 However, as disclosed in Patent Documents 1 and 2 described above, even if the shape of the knob portion is devised, the following problems occur. That is, this type of deep-drawn type packaging body forms a pocket portion in the lower film, puts contents to be packaged in the pocket portion, covers the upper film, and covers the pocket portion of the lower film. By sandwiching and heating the unformed region and the film portion of the upper film facing it from above and below, the periphery of the pocket portion is welded and sealed to seal the inside of the pocket portion. At this time, the region constituting the knob portion is not sealed by not applying pressure (providing a recess in a part of the seal surface of the sealer of the seal device). After that, a horizontal cut is made in a predetermined position of the fusion-sealed portion, that is, between the front and rear pocket portions and in a direction perpendicular to the film transport direction, and then the left and right pocket portions (the pockets aligned in the horizontal direction). Part) is vertically cut along the film transport direction, whereby individual deep-drawn packages are produced.

そして、縦カットや横カットする際に、摘み部分となる未シール状態の領域の所定位置をカットすることで、製造された深絞り型包装体における摘み部分は、その周縁がフリーとなる。しかし、実際には、図１（ｂ）に示すように、横カット処理にともない、摘み部分となるべき未シールの領域の一部において、上側フィルムと下側フィルムとが付着されてしまうことがある。これは、通常横カットを行うカッター装置は、押し切りカッターであり、交換可能な刃と、その刃の受け部とにより上下フィルムのカットを行っている。そのため、特に、カッターの刃先が摩耗して切れ味が低下してくると、カッターの刃（所定の幅を持つ）と受け部との間で上側フィルムと下側フィルムとが所定の力で加圧されることになり、横カットを行う横カッター装置は、上下のフィルムを熱シールするシール装置のすぐ後に設けられることから、横カッター装置の刃と受け部とで挟み込まれた上側フィルムと下側フィルムは、ある程度の高い温度となっていることもあいまって、挟み込まれた部分で軽く両フィルム同士が互いに付着してしまう。 Then, when the vertical cut or the horizontal cut is performed, by cutting a predetermined position of the unsealed region that becomes the pick portion, the peripheral portion of the pick portion in the manufactured deep-drawn package is free. However, in actuality, as shown in FIG. 1B, the upper film and the lower film may be attached to a part of the unsealed region that should be the picking portion in accordance with the horizontal cutting process. is there. The cutter device that normally performs a transverse cut is a push-cut cutter, and cuts the upper and lower films by an exchangeable blade and a receiving portion of the blade. Therefore, especially when the cutting edge of the cutter is worn and the sharpness is reduced, the upper film and the lower film are pressed with a predetermined force between the cutter blade (having a predetermined width) and the receiving portion. Since the horizontal cutter device for performing the horizontal cut is provided immediately after the sealing device for heat-sealing the upper and lower films, the upper film and lower side sandwiched between the blade and the receiving portion of the horizontal cutter device Along with the fact that the film has a certain high temperature, the two films are lightly attached to each other at the sandwiched portion.

このため包装体の開封するためには、まず上側フィルムと下側フィルムを分離して摘み部分をフリー状態にして指等で掴み持つことができるようにする必要がある。もちろん、カッターの刃や受け部には、シール装置のようにヒータ等が内蔵されているわけではないので、熱融着されている部位ほどには接着強度が強くならず、摘み部分をフリー状態にするために上側フィルムと下側フィルムとを分離することはできるものの、係る一作業が必要となるためユーザにとっては煩雑であることには違いがない。 For this reason, in order to open the package, it is necessary to first separate the upper film and the lower film so that the grip portion is in a free state so that it can be held with a finger or the like. Of course, the cutter blade and the receiving part do not have a built-in heater like the sealing device, so the adhesive strength is not as strong as the heat-sealed part, and the knob part is in a free state. Although the upper film and the lower film can be separated in order to achieve the above, there is no difference in being troublesome for the user because one operation is required.

本発明は、上側フィルムと下側フィルムとの間に確実に間隙を形成し、摘み部分を形成することができる深絞り型包装機および深絞り型包装システムを提供することを目的とする。 An object of the present invention is to provide a deep-drawing type packaging machine and a deep-drawing type packaging system in which a gap can be surely formed between an upper film and a lower film and a knob portion can be formed.

上述した目的を達成するために、本発明に係る深絞り型包装機は、前提として下記の（ａ），（ｂ）の構成を備える。（ａ）間欠的に搬送される硬質の下側フィルムに対し、凹状のポケット部を成型する成型装置と、その成型装置の下流側に配置され、前記ポケット部内に被包装物が挿入された状態の前記下側フィルムに対して軟質の上側フィルムを被覆する手段と、前記下側フィルムの前記ポケット部が形成されていないフィルム部位と、それに接触する前記上側フィルムのフィルム部位のうち、前記ポケット部の外周囲を囲む領域をシールして前記ポケット部を密封するシール手段と、前記下側フィルムと前記上側フィルムの前記シールされた所定部位を搬送方向と交差する横方向にカットする横カッター手段と、その横カッター手段の下流側に配置され、前記下側フィルム並びに前記上側フィルムの前記シールされた所定部位を搬送方向に沿ってカットする縦カッター手段と、を備えた深絞り型包装機において、前記シール手段は、前記下側フィルムの前記ポケット部が形成されていないフィルム部位と、それに接触する前記上側フィルムのフィルム部位のうちの一部を未シール部として摘み部分を形成する機能を持ち、前記横方向のカット位置は前記摘み部分を含むように設定し、前記横カッター手段は、少なくとも前記摘み部分を含んで搬送方向にも一部カットする機能を持ち、前記横カッター手段の下流側に、前記摘み部分を下方に折り曲げる折り曲げ手段を配置するようにした。 In order to achieve the above-described object, the deep drawing type packaging machine according to the present invention has the following configurations (a) and (b) as a premise. (A) A molding device that molds a concave pocket portion with respect to a hard lower film that is intermittently transported, and a state in which an object to be packaged is inserted into the pocket portion, which is disposed downstream of the molding device. Among the means for covering the lower film with a soft upper film, the film part where the pocket part of the lower film is not formed, and the film part of the upper film in contact therewith, the pocket part Sealing means for sealing an area surrounding the outer periphery of the sealing member to seal the pocket portion, and a horizontal cutter means for cutting the sealed predetermined portion of the lower film and the upper film in a transverse direction intersecting a conveying direction; , Arranged on the downstream side of the lateral cutter means, and cut the sealed predetermined portion of the lower film and the upper film along the conveying direction In the deep drawing type packaging machine provided with the vertical cutter means, the sealing means includes a film part in which the pocket portion of the lower film is not formed and a film part of the upper film in contact with the film part. It has a function of forming a knob part with a part as an unsealed part, the horizontal cutting position is set so as to include the knob part, and the horizontal cutter means includes at least the knob part in the transport direction as well. A bending means having a function of partially cutting and bending the knob portion downward is arranged on the downstream side of the horizontal cutter means.

硬質と軟質は、相対的なものであり、折り曲げ加工・処理をした場合に、その折り曲げられた状態・形態を保持するのが硬質なフィルムとなり、その折り曲げられた状態を保持しないのが軟質なフィルムとなる。この硬質と軟質は、実施形態で例示列挙したように、その構成する材質の種類自体を異ならせるようにしてもよいし、フィルムの厚さを変える（薄い方が軟質）ことによっても実現できる。また、実施形態で示した材質は、一例であり、他の材質を用いてももちろん良い。 Hard and soft are relative, and when folded and processed, the folded state and form will be a hard film, and the folded state will be soft. Become a film. The hard and soft materials can be realized by changing the kind of material constituting itself, as exemplified and enumerated in the embodiment, or by changing the thickness of the film (the thinner one is softer). Moreover, the material shown in the embodiment is an example, and other materials may be used.

この発明によれば、横カッター手段で摘み部分の周囲の適宜位置がカットされ、その後に、折り曲げ手段によってその摘み部分が下方に付勢されて折り曲げられる。すると、本発明では、下側フィルムは硬質なフィルムを用いているので、折り曲げ手段により折り曲げられた状態を保持するが、上側フィルムは軟質なフィルムを用いているので折り曲げ手段による下方への付勢力が解除すると、元の状態に戻ろうとする（少なくとも、折り曲げられた状態を維持することはない）。その結果、上側フィルムと下側フィルムとの間に確実に隙間を形成することが可能となり、深絞り型包装体の開封を容易に行うことができる。 According to the present invention, an appropriate position around the picked portion is cut by the horizontal cutter means, and thereafter, the picked portion is urged downward and bent by the bending means. Then, in the present invention, since the lower film uses a hard film, it keeps the folded state by the folding means, but the upper film uses a soft film, so the downward biasing force by the folding means is maintained. When is released, it tries to return to the original state (at least it does not maintain the folded state). As a result, it is possible to reliably form a gap between the upper film and the lower film, and the deep-drawn package can be easily opened.

このように個々の深絞り型包装体に分離した後で、折り曲げ装置により摘み部分を折り曲げるようにしても、上記の（１），（２）の発明と同様に、摘み部分の上側フィルムと下側フィルムとの間に隙間を形成することができ、開封容易な包装体とすることができる。 Even if the knob part is folded by a folding device after being separated into individual deep-drawn packages in this way, the upper film and the lower part of the knob part can be folded in the same manner as in the inventions (1) and (2) above. it is possible to form a gap between the side film as possible out to the easy-open packaging.

本発明は、フィルムの所定位置を切断した後に、摘み部分となる部分を折り曲げるための折り曲げ手段（折り曲げ装置）を設けたので、上側フィルムと下側フィルムとの間に確実に隙間を形成することが可能となり、深絞り型包装体の開封を容易に行うことができる。 In the present invention, after a predetermined position of the film is cut, a folding means (folding device) is provided to bend the portion that becomes the knob portion, so that a gap is surely formed between the upper film and the lower film. The deep-drawn package can be easily opened.

図２は、本発明の好適な一実施の形態を示している。本実施形態の深絞り型包装機は、上流側に配置された原反ロール１０から連続して引き出された下側フィルム１１を水平方向に搬送するフィルム搬送装置１２を備える。このフィルム搬送装置１２は、下側フィルム１１の両側縁の外側に配置された一対のエンドレスチェーンと、そのエンドレスチェーンに取り付けられた下側フィルム１１の長手方向の両側縁を掴む多数の爪と、を備え、係る爪にて下側フィルム１１の両側縁を掴んだ状態で搬送する。なお、下側フィルム１１は、延伸フィルム等の比較的硬質なフィルムが用いられる。 FIG. 2 shows a preferred embodiment of the present invention. The deep-drawing type packaging machine according to the present embodiment includes a film transport device 12 that transports the lower film 11 continuously drawn out from the original fabric roll 10 disposed on the upstream side in the horizontal direction. The film transporting device 12 includes a pair of endless chains disposed outside both side edges of the lower film 11, a plurality of claws that grip both side edges in the longitudinal direction of the lower film 11 attached to the endless chain, It conveys in the state which grasped both the side edges of the lower film 11 with the nail | claw which concerns. The lower film 11 is a relatively hard film such as a stretched film.

このフィルム搬送装置１２の搬送途中の上流側には、成型装置１３が配置される。この成形装置１３は、下側フィルム１１を真空吸引し、下側に突出する凹状のポケット部１４を成型する。そして、成型装置１３の下流側の所定位置にて、ポケット部１４内に被包装物を自動或いは手動にて供給するようにしている。上記のように、下側フィルム１１は、比較的硬質なフィルムを用いて構成されているので、一旦ポケット部１４が形成されたならば、その形状を保持する。 A molding device 13 is arranged on the upstream side of the film transport device 12 in the middle of transport. The molding apparatus 13 vacuum-sucks the lower film 11 and molds a concave pocket portion 14 that protrudes downward. Then, an article to be packaged is supplied automatically or manually into the pocket portion 14 at a predetermined position on the downstream side of the molding apparatus 13. As described above, since the lower film 11 is formed using a relatively hard film, once the pocket portion 14 is formed, the shape of the lower film 11 is maintained.

一方、下側フィルムの搬送ラインの上方には、別の原反ロール１５が設置されており、この原反ロール１５から連続して上側フィルム1６が引き出され、その引き出された上側フィルム１６は、上記被包装物の供給地点の下流側所定位置にて下側フィルム１１の上に重ね合わされるようになっている。なお、上側フィルム１６は、ＰＥ，ＰＥＴ等の比較的軟質なフィルムが用いられる。 On the other hand, another original fabric roll 15 is installed above the lower film conveyance line, and the upper film 16 is continuously drawn out from the original fabric roll 15. It is overlaid on the lower film 11 at a predetermined position downstream of the supply point of the package. For the upper film 16, a relatively soft film such as PE or PET is used.

この両フィルム１１，１６の重合地点の下流側には、シール装置１７が配置され、このシール装置１７にて、下側フィルム１１と上側フィルム１６の所定位置、つまり、ポケット部１４の周囲の両フィルム１１，１６の接触部位を上下から挟み込むとともに加熱して熱シールする。これにより、被包装物がポケット部１４内に密封される。また、このシール装置１７にポケット部１４内の空気を吸引除去する機能を設け、両フィルム１１，１６を熱シールする前にポケット部１４内の空気を吸引除去することで、被包装物がポケット部１４内にて真空状態で密封するように構成する場合もある。また、吸引除去する機能に替えて、所定のガスを充填する機能を設けることで、ポケット部１４内を窒素等の不活性ガスに置換することもできる。さらにシール装置１７は、ポケット部１４が形成されていない下側フィルム１１と上側フィルム１６の対向するフィルムのほぼ全面をシールするようになっているが、シール面の一部に凹部を設け、フィルムの一部の領域に未シール部を形成するようになっている。この未シール部を形成する領域は、ポケット部１４の４つの角部のうちの１つの先端側とし、最終的な包装体における摘み部分を構成する位置としている。係る構成は、従来と同様にものを用いることができる。なお、この摘み部分は、上側フィルム１６と下側フィルム１１とが未接着状態で、その未接着状態でフリーとなっている上側フィルム１６をつまむと共に、上側に引っ張ることで、上側フィルム１６が下側フィルム１１から離反し、包装体を容易に開封するためのものである。 A sealing device 17 is arranged on the downstream side of the polymerization point of both the films 11 and 16, and in this sealing device 17, a predetermined position of the lower film 11 and the upper film 16, that is, both around the pocket portion 14. The contact portions of the films 11 and 16 are sandwiched from above and below and heated to be heat sealed. Thereby, the article to be packaged is sealed in the pocket portion 14. Further, the sealing device 17 is provided with a function of sucking and removing the air in the pocket portion 14, and by sucking and removing the air in the pocket portion 14 before heat-sealing the films 11 and 16, the item to be packaged is pocketed. There may be a case in which the inside of the portion 14 is sealed in a vacuum state. In addition, the inside of the pocket portion 14 can be replaced with an inert gas such as nitrogen by providing a function of filling a predetermined gas instead of the function of suction removal. Further, the sealing device 17 is configured to seal almost the entire surface of the opposing film of the lower film 11 and the upper film 16 in which the pocket portion 14 is not formed. An unsealed portion is formed in a part of the region. The region where the unsealed portion is formed is the tip side of one of the four corners of the pocket portion 14 and is a position that constitutes a knob portion in the final package. Such a configuration can be the same as the conventional one. In addition, the upper film 16 and the lower film 11 are not adhered to each other, and the upper film 16 is pulled down by pinching the upper film 16 that is free in the unbonded state. It is for separating from the side film 11 and opening the package easily.

シール装置１７のさらに下流側には、横カッター装置１８並びに縦カッター装置１９が順次設けられ、両フィルム１１，１６のシール部位を横方向，縦方向にそれぞれカットすることにより、個々の深絞り型包装体ごとに分離製造する。 On the further downstream side of the sealing device 17, a horizontal cutter device 18 and a vertical cutter device 19 are sequentially provided. By cutting the sealing portions of both the films 11 and 16 in the horizontal direction and the vertical direction, the individual deep drawing type Separately manufactured for each package.

横カッター装置１８は、フィルムを挟んで上下に配置されるカッター刃１８ａと、受け部１８ｂと、を備え、それらカッター刃１８ａ，受け部１８ｂはシリンダ１８ｃ等の駆動手段によりタイミングを合わせて昇降移動する。この横カッター装置１８は、押し切りカッターであり、カッター刃１８ａの刃の形状に沿って下側，上側フィルム１１，１６が切断される。そして、本実施形態では、下側，上側フィルム１１，１６を横方向（搬送方向と直交する方向）に切断するための直線状の刃部ととともに、最終的な包装体における角に丸みを形成するためのＲカット用の刃部を備える。これにより、横カッター装置１８を通過すると、図３に示すようなカットラインＫＬが形成され、下側，上側フィルム１１，１６は、横方向には完全に切断（両端は、フィルム搬送装置１２の爪部１２により把持されている）されるとともに、最終的な包装体における角部が打ち抜かれて所定形状の孔部Ｋが形成される。また、上記のＲカットされた部分は、シール装置１７にて下側フィルム１１と上側フィルム１６とがシールされずに形成される摘み部分Ｔの形成領域に望むようになっている。 The horizontal cutter device 18 includes a cutter blade 18a and a receiving portion 18b arranged above and below with a film interposed therebetween. The cutter blade 18a and the receiving portion 18b are moved up and down in synchronization by a driving means such as a cylinder 18c. To do. The horizontal cutter device 18 is a push cutter, and the lower and upper films 11 and 16 are cut along the shape of the cutter blade 18a. And in this embodiment, the roundness is formed in the corner | angular in a final package body with the linear blade part for cut | disconnecting the lower side and upper side films 11 and 16 to a horizontal direction (direction orthogonal to a conveyance direction). An R-cut blade is provided. As a result, the cut line KL as shown in FIG. 3 is formed when passing through the horizontal cutter device 18, and the lower and upper films 11 and 16 are completely cut in the horizontal direction (both ends of the film conveying device 12). And a corner portion of the final package is punched to form a hole K having a predetermined shape. Further, the R-cut portion is desired in a formation region of a knob portion T formed by the sealing device 17 so that the lower film 11 and the upper film 16 are not sealed.

また、縦カッター装置１９は、フィルムの搬送方向と直交する方向に回転軸を有する上下一対の円盤型のカッターを複数組備え、上下のカッターにて下側，上側フィルム１１，１６を挟み込むことで搬送方向と平行にカットする。本実施形態では、図３に示すように、ポケット部１４が横一列で３個形成するため、左右のポケット部１４の間と、両サイドを切断する必要があり、合計４組のカッターを有する。下側，上側フィルム１１，１６が、縦カッター装置１９を通過することで切断されるフィルム位置は、横カッター装置１８で打ち抜かれた孔部Ｋを結ぶ線となる。よって、縦カッター装置１９を通過することで、ポケット部１４の周囲が切断されて、個々の深絞り型包装体が製造される。そして、その製造される深絞り型包装体は、四隅の頂点部分がＲカットされて丸みを帯びた形状となる。 The vertical cutter device 19 includes a plurality of pairs of upper and lower disk-shaped cutters having a rotation axis in a direction orthogonal to the film conveyance direction, and sandwiches the lower and upper films 11 and 16 with the upper and lower cutters. Cut parallel to the transport direction. In the present embodiment, as shown in FIG. 3, since three pocket portions 14 are formed in a horizontal row, it is necessary to cut both sides of the left and right pocket portions 14, and a total of four sets of cutters are provided. . The film position at which the lower and upper films 11 and 16 are cut by passing through the vertical cutter device 19 is a line connecting the holes K punched by the horizontal cutter device 18. Therefore, the periphery of the pocket part 14 is cut | disconnected by passing the vertical cutter apparatus 19, and each deep drawing type package is manufactured. The manufactured deep-drawn package has a rounded shape with R-cuts at the four corners.

ここで本実施形態では、横カッター装置１８と縦カッター装置１９の間に、折り曲げ装置２０を設けている。この折り曲げ装置２０は、摘み部分Ｔを構成する部分の折り曲げを行うもので、具体的には図４に示すように構成される。 Here, in the present embodiment, a bending device 20 is provided between the horizontal cutter device 18 and the vertical cutter device 19. The bending device 20 performs bending of a portion constituting the knob portion T, and is specifically configured as shown in FIG.

折り曲げ装置２０は、フィルムの上方側に摘み部分Ｔの折り曲げを行うために下方に付勢する付勢部材２１と、摘み部分以外の部分を抑える抑え部材２２を配置し、フィルムの下方側に受け部材２３を配置した構成を採る。付勢部材２１と抑え部材２２は、第１シリンダ２４に連結され昇降移動する基板２５の下面に取り付けられる。このとき、付勢部材２１は、摘み部分Ｔに対向する位置に配置され、基板２５に直接固定されている。よって、第１シリンダ２４の動きに合わせて基板２５と一体になって昇降移動する。また、付勢部材２１は、その下端面２１ａが、傾斜面（テーパー面）となる。この下端面２１ａは、内側から外側に向けて徐々にその下端位置が下方に位置するような形状を採る。そして、第１シリンダ２４の動作にともない付勢部材２１が下降移動した場合、その下端面２１ａが、摘み部分Ｔを構成する下側フィルム１１，上側フィルム１６を下方に押し下げるような寸法・形状に設定される。 The folding device 20 is provided with an urging member 21 that urges downward to fold the knob portion T on the upper side of the film and a holding member 22 that suppresses a portion other than the knob portion, and is received on the lower side of the film. The structure which has arrange | positioned the member 23 is taken. The urging member 21 and the holding member 22 are attached to the lower surface of the substrate 25 that is connected to the first cylinder 24 and moves up and down. At this time, the urging member 21 is disposed at a position facing the knob portion T and is directly fixed to the substrate 25. Therefore, it moves up and down integrally with the substrate 25 in accordance with the movement of the first cylinder 24. Further, the lower end surface 21a of the urging member 21 is an inclined surface (tapered surface). The lower end surface 21a takes a shape such that the lower end position is gradually positioned downward from the inside toward the outside. When the urging member 21 moves downward in accordance with the operation of the first cylinder 24, the lower end surface 21a has such a size and shape as to push down the lower film 11 and the upper film 16 constituting the knob portion T. Is set.

抑え部材２２は、上側フィルムのほぼ全面（上記の付勢部材２１の設置領域を除く）に接触可能な平板からなり、その上面に連結された支持軸２８を介して基板２５に吊り下げ支持される。基板２５には上下に貫通する貫通孔が形成され、支持軸２８はその貫通孔内を貫通してその上端を基板２５の上面よりも突出させ、その状態で支持軸２８の上端の突出部位に止め金具（たとえばナットなど）を連結する。支持軸２８は、基板２５に設けた貫通孔に沿って昇降移動し、止め金具が基板２５の上面に接触した状態ではそれ以上の下降移動が抑止される。さらに、基板２５の下方に位置する支持軸２８には、コイルスプリング等のバネ２６が装着され、そのバネ２６の両端は、基板２５の下面と抑え部材２２の上面に接触する。よって、抑え部材２２は、基板２５の昇降に追従して昇降移動するものの、下降移動中に抑え部材２２に対して反力としてバネ２６の弾性力以上の力が加わった場合には、抑え部材２２は下降移動を停止し、さらに基板２５が下降移動しようとした場合にはバネ２６が弾性変形（圧縮変形）して基板２５の下降移動を許容する（支持軸２８が相対的に基板２５に対して上昇移動する）。 The holding member 22 is a flat plate that can contact almost the entire surface of the upper film (excluding the installation area of the biasing member 21), and is supported by being suspended from the substrate 25 via a support shaft 28 connected to the upper surface. The A through-hole penetrating vertically is formed in the substrate 25, and the support shaft 28 penetrates through the through-hole so that its upper end protrudes from the upper surface of the substrate 25, and in this state, the projecting portion at the upper end of the support shaft 28 is formed. Connect fasteners (such as nuts). The support shaft 28 moves up and down along the through-hole provided in the substrate 25, and further downward movement is suppressed in a state where the stopper is in contact with the upper surface of the substrate 25. Further, a spring 26 such as a coil spring is attached to the support shaft 28 positioned below the substrate 25, and both ends of the spring 26 are in contact with the lower surface of the substrate 25 and the upper surface of the holding member 22. Therefore, although the restraining member 22 moves up and down following the raising and lowering of the substrate 25, when a force greater than the elastic force of the spring 26 is applied as a reaction force to the restraining member 22 during the downward movement, the restraining member. 22 stops the downward movement, and further, when the substrate 25 is about to move downward, the spring 26 is elastically deformed (compressed) to allow the substrate 25 to move downward (the support shaft 28 is relatively relative to the substrate 25). Move up against).

バネ２６は、コイルスプリングに限ることはなく、板バネその他の各種の構成のものを用いることができる。さらに、ゴム等の弾性部材を用いることもできる。この抑え部材２２は、付勢部材２１により摘み部分Ｔを下方に付勢した際に、その他のフィルム部分（特に、摘み部分Ｔ近傍）が持ち上がってしまい摘み部分Ｔを折り曲げることができなくなることを抑制するためのものである。よって、係る持ち上がりが防止できる程度の弾性力を有していればよい。さらに、摘み部分Ｔの近傍のシールされたフィルム部位の持ち上がりを防止できればよいので、たとえば、抑え部材２２がある程度の重さがあり、自重によりフィルム部分の持ち上がりを抑えることができれば、必ずしもバネその他の弾性部材を設けなくても良い。この場合に、付勢部材２１の下端面２１ａの位置と、抑え部材２２の下面の位置が相対的に昇降移動する必要があるので、上記のように支持軸を用いて基板２５に連結しても良い。また、基板２５に対してガイドレールやその他の機構により相対的に昇降移動可能に抑え部材２２を連結するようにしてもよい。 The spring 26 is not limited to a coil spring, and a leaf spring and other various configurations can be used. Further, an elastic member such as rubber can be used. When the knob portion T is urged downward by the urging member 21, the holding member 22 is lifted by other film portions (particularly, in the vicinity of the knob portion T), and the knob portion T cannot be bent. It is for suppressing. Therefore, it is only necessary to have an elastic force that can prevent such lifting. Furthermore, since it is only necessary to prevent the sealed film portion in the vicinity of the knob portion T from being lifted, for example, if the restraining member 22 has a certain amount of weight and can suppress the lifting of the film portion by its own weight, it is not always necessary to use a spring or the like. The elastic member may not be provided. In this case, since the position of the lower end surface 21a of the urging member 21 and the position of the lower surface of the holding member 22 need to move up and down relatively, it is connected to the substrate 25 using the support shaft as described above. Also good. Further, the restraining member 22 may be connected to the substrate 25 so as to be relatively movable up and down by a guide rail or other mechanism.

さらにまた、抑え部材２２は、本実施形態では、上側フィルム１６のほぼ全面を覆う平板から構成したが、たとえば、下側フィルム１１と上側フィルム１６のシール部分に接触するようにしたり（ポケット部１４の上方では接触しない）、摘み部分Ｔの近傍のシール部分のみと接触するようにした形状の他、任意の形状を採ることができる。 Furthermore, in the present embodiment, the holding member 22 is composed of a flat plate that covers almost the entire surface of the upper film 16. However, for example, the holding member 22 may be in contact with the seal portions of the lower film 11 and the upper film 16 (pocket portion 14). In addition to the shape that is in contact with only the seal portion in the vicinity of the knob portion T, any shape can be adopted.

一方、受け部材２３は、上面にポケット部１４が挿入する凹所２３ａが形成された矩形状の枠を有し、その下方に設けられた第２シリンダ２７に連結される。よって、受け部材２３は、第２シリンダ２７の動作に連動して昇降移動し、上方位置においては、下側フィルム１１のシールされたフィルム部位の下面に接触する。さらに、受け部材２３の上面のうち、摘み部分Ｔに対応する部分は、平面三角形状の凹部２３ｂが形成されている。 On the other hand, the receiving member 23 has a rectangular frame in which a recess 23a into which the pocket portion 14 is inserted is formed on the upper surface, and is connected to a second cylinder 27 provided therebelow. Therefore, the receiving member 23 moves up and down in conjunction with the operation of the second cylinder 27 and contacts the lower surface of the sealed film portion of the lower film 11 at the upper position. Further, a portion corresponding to the knob portion T of the upper surface of the receiving member 23 is formed with a concave portion 23b having a planar triangle shape.

第１，第２シリンダ２４，２７は同期して往復移動し、付勢部材２１，抑え部材２２と、受け部材２３とは、同期して接近離反移動し、接近した状態では、下側フィルム１１，上側フィルム１６のシール部分が、抑え部材２２と受け部材２３とで挟み込まれるようになっている。 The first and second cylinders 24 and 27 reciprocate synchronously, and the urging member 21, the restraining member 22 and the receiving member 23 move close to and away from each other synchronously. The sealing portion of the upper film 16 is sandwiched between the holding member 22 and the receiving member 23.

次に、本実施形態の要部となる上記の折り曲げ装置２０の作用を説明する。図５（ａ）に示すように、基本状態では、付勢部材２１，抑え部材２２は上昇位置にあり、受け部材２３は下降位置にあり、共に、下側フィルム１１並びに上側フィルム１６とは非接触となる。よって、フィルム搬送装置１２の動作にともない、下側フィルム１１と上側フィルム１６とは、シール装置１７にて適宜位置がシールされて一体化した状態のまま搬送される。 Next, the operation of the bending apparatus 20 that is a main part of the present embodiment will be described. As shown in FIG. 5A, in the basic state, the urging member 21 and the holding member 22 are in the raised position, and the receiving member 23 is in the lowered position, both of which are not in contact with the lower film 11 and the upper film 16. Contact. Therefore, the lower film 11 and the upper film 16 are transported in an integrated state in which the positions are appropriately sealed by the seal device 17 in accordance with the operation of the film transport device 12.

フィルム搬送装置１２は、下側フィルム１１と上側フィルム１６とを間欠状態で搬送するもので、ポケット部１４が受け部材２３の凹所２３ａ上に位置したときに両フィルム１１，１６搬送が一時停止する。この一時停止している期間において、成型装置１３においては下側フィルム１１に対してポケット部を形成し、シール装置１７においては下側フィルム１１と上側フィルム１６との所定位置を熱シールし、横カッター装置１８では下側フィルム１１と上側フィルム１６の所定位置をカットする処理を行う。そして、折り曲げ装置２０は、第１，第２シリンダ２４，２７が作動し、基板２５（付勢部材２１、抑え部材２２）は下降移動し、受け部材２３は上昇移動する。すると、図５（ｂ）に示すように、抑え部材２２の下面が上側フィルム１６のほぼ全面と接触すると共に、付勢部材２１の下端面２１ａの先端が上側フィルム１６の摘み部分Ｔの形成領域に接触する。また、受け部材２３は、下側フィルム１１のシール部分に接触する。これにより、下側フィルム１１と上側フィルム１６のシール部分は、その上下から抑え部材２２と受け部材２３とで挟み込まれる。 The film transport device 12 transports the lower film 11 and the upper film 16 in an intermittent state. When the pocket portion 14 is positioned on the recess 23a of the receiving member 23, the transport of both the films 11 and 16 is temporarily stopped. To do. During this temporary stop period, the molding device 13 forms a pocket portion with respect to the lower film 11, and the sealing device 17 heat seals a predetermined position between the lower film 11 and the upper film 16, The cutter device 18 performs processing for cutting predetermined positions of the lower film 11 and the upper film 16. In the bending apparatus 20, the first and second cylinders 24 and 27 are operated, the substrate 25 (the urging member 21 and the holding member 22) is moved downward, and the receiving member 23 is moved upward. Then, as shown in FIG. 5 (b), the lower surface of the restraining member 22 comes into contact with almost the entire surface of the upper film 16, and the tip of the lower end surface 21 a of the urging member 21 is the formation region of the knob portion T of the upper film 16. To touch. Further, the receiving member 23 comes into contact with the seal portion of the lower film 11. Thereby, the sealing part of the lower film 11 and the upper film 16 is sandwiched between the holding member 22 and the receiving member 23 from above and below.

さらに上側の第１シリンダ２４のシリンダロッドが下降すると、基板２５が下降し、それにともない付勢部材２１も下降するため、その下端面２１ａが接触する摘み部分Ｔを下方に付勢する。このとき、抑え部材２２はそれ以上下降移動しないため、図５（ｃ）に示すように摘み部分Ｔを下方に折り曲げる。つまり、摘み部分Ｔは、下端面２１ａに沿って傾斜する。 Further, when the cylinder rod of the upper first cylinder 24 is lowered, the base plate 25 is lowered, and the urging member 21 is also lowered accordingly, so that the knob portion T with which the lower end surface 21a contacts is urged downward. At this time, since the holding member 22 does not move downward any more, the knob portion T is bent downward as shown in FIG. That is, the knob portion T is inclined along the lower end surface 21a.

その後、上下の第１，第２シリンダ２４，２６が逆方向（シリンダロッドが本体内に収納される方向）に作動し、付勢部材２１，抑え部材２２並びに受け部材２３は、離反し、図５（ｄ）に示すようにそれぞれの基準位置に復帰する。すると、上側フィルム１６は軟質フィルムであるので、変形させても元に戻るが、下側フィルム１１は硬質フィルムであるので変形が維持される。よって、図示するように、下側フィルム１１のみが曲がった状態を保つので、下側フィルム１１と上側フィルム１６との間に間隙が形成される。また、仮に横カッター装置１８にてカット処理される際に、下側フィルム１１と上側フィルム１６とが付着したとしても、その付着の力は弱いので剥がれる。 Thereafter, the upper and lower first and second cylinders 24 and 26 operate in the reverse direction (the direction in which the cylinder rod is accommodated in the main body), and the urging member 21, the holding member 22 and the receiving member 23 are separated from each other. As shown in FIG. 5 (d), each reference position is restored. Then, since the upper film 16 is a soft film, it returns even if it is deformed, but the lower film 11 is a hard film, so that the deformation is maintained. Therefore, as shown in the drawing, only the lower film 11 is kept bent, so that a gap is formed between the lower film 11 and the upper film 16. Moreover, even if the lower film 11 and the upper film 16 adhere to each other when the cutting process is performed by the horizontal cutter device 18, the adhesion force is weak, so that the film is peeled off.

図４，図５では、図示の便宜上、１つの包装体の摘み部分Ｔを折り曲げるための構成を示したが、実際には上記の付勢部材２１，抑え部材２２並びに受け部材２３は、少なくとも横一列に存在する３個分の包装体（ポケット部１４並びに摘み部分Ｔ）に対して処理する必要がある。よって、たとえば、図４に示す構成のものを横一列に３個並べても良いし、抑え部材並びに受け部材を、横一列の３個分をまとめて挟み込むことができるような形態（受け部材は、横長な矩形状本体の上面所定位置に３個の凹所を形成し、抑え部材は横長な平板とし、さらに、所定の３カ所に付勢部材を取り付ける形態）にしたりするなど各種の構成を採ることができる。そして、本実施形態では、図２にも示すように、前後の２列分（合計６個）に対して一括して折り曲げ処理ができるようにしている。 4 and 5, for convenience of illustration, a configuration for bending the knob portion T of one package is shown. Actually, the biasing member 21, the holding member 22, and the receiving member 23 are at least sideways. It is necessary to process the package (pocket part 14 and knob part T) for three pieces existing in a row. Therefore, for example, three of the configurations shown in FIG. 4 may be arranged in a horizontal row, or a configuration in which the holding member and the receiving member can be sandwiched together in three horizontal rows (the receiving member is Various configurations are adopted such as three recesses are formed at predetermined positions on the upper surface of the horizontally long rectangular main body, the holding member is a horizontally long flat plate, and a biasing member is attached to the three predetermined positions. be able to. In this embodiment, as shown in FIG. 2, the bending process can be performed collectively for the front and rear two rows (6 in total).

図６は本発明の別の実施形態を示している。本実施形態では、上記の実施形態を基本とし、受け部材の構造を変えている。すなわち、本実施形態では、受け部材２３′として、搬送方向に延びるように平行に配置された複数本のガイドレールから構成するようにした。このガイドレールは、ポケット部１４の非形成領域となる下側フィルム１１と上側フィルム１６のシール部分に対向する位置に配置し、さらに、摘み部分Ｔに対向する領域に平面三角形状の凹部２３ｂ′を設けている。 FIG. 6 shows another embodiment of the present invention. In the present embodiment, the structure of the receiving member is changed based on the above-described embodiment. In other words, in the present embodiment, the receiving member 23 'is composed of a plurality of guide rails arranged in parallel so as to extend in the transport direction. This guide rail is disposed at a position facing the seal portions of the lower film 11 and the upper film 16 that are non-formation regions of the pocket portion 14, and further, a planar triangular recess 23b ′ is formed in the region facing the knob portion T. Is provided.

係る構成を採ると、受け部材２３′は、下側フィルム１１（ポケット部１４）の搬送の邪魔にならないので、下側フィルム１１に対して常時接触或いは近接する位置に設置でき、下側シリンダが不要となる。なお、その他の構成並びに作用効果は、上記の作用効果と同様であるので、その詳細な説明を省略する。 When such a configuration is adopted, the receiving member 23 ′ does not interfere with the conveyance of the lower film 11 (pocket portion 14), and therefore can be installed at a position that is always in contact with or close to the lower film 11. It becomes unnecessary. In addition, since another structure and effect are the same as said effect, the detailed description is abbreviate | omitted.

なお、上述した各実施形態では、いずれも横カッター装置１８と縦カッター装置１９の間に折り曲げ装置２０を配置した深絞り型包装機について説明したが、本発明はこれに限ることはなく、縦カッター装置１９の下流側に折り曲げ装置２０を配置しても良い。この場合に、折り曲げ装置２０は、深絞り型包装機の１つの構成要素として実現しても良いし、深絞り型包装機とは別の装置として深絞り型包装機の下流側に設置し、深絞り型包装機から搬出される包装体の摘み部分に対して折り曲げ装置で折り曲げ加工をするような深絞り型包装システムとして構築しても良い。 In each of the above-described embodiments, the deep-drawing type packaging machine in which the folding device 20 is disposed between the horizontal cutter device 18 and the vertical cutter device 19 has been described. However, the present invention is not limited to this, and the vertical The bending device 20 may be disposed on the downstream side of the cutter device 19. In this case, the folding device 20 may be realized as one component of the deep-drawing type packaging machine, or installed on the downstream side of the deep-drawing type packaging machine as a separate device from the deep-drawing type packaging machine, You may construct | assemble as a deep drawing type packaging system which bends with the bending apparatus with respect to the picking part of the package body carried out from a deep drawing type packaging machine.
