以下に本発明を、その好ましい実施形態に基づき図面を参照しながら説明する。図1には、本発明の包装体の製造装置の一実施形態の構造が示されている。製造装置10は、被包装物5がフィルムで包装された包装体1を製造するものである。同図に示す製造装置10は、第1フィルム接合部20、ノズル部30、第2フィルム接合部40及びカッター部50を備えている。 Hereinafter, the present invention will be described based on the preferred embodiment with reference to the drawings. FIG. 1 shows the structure of an embodiment of the packaging manufacturing apparatus of the present invention. The manufacturing apparatus 10 manufactures a package 1 in which the object to be packaged 5 is packaged with a film. The manufacturing apparatus 10 shown in the figure includes a first film joining portion 20, a nozzle portion 30, a second film joining portion 40, and a cutter portion 50.

第1フィルム接合部20は、搬送方向MDに搬送されているフィルムの原反の側部どうしを搬送方向MDに沿って接合する装置である。図1に示すように、搬送方向MDに搬送されているフィルムの第1原反11(以下、これを「第1フィルム原反11」ともいう。)と、該原反11と同一方向に搬送されているフィルムの第2原反12(以下、これを「第2フィルム原反12」ともいう。)とはそれぞれ同一の幅を有しており、両原反11,12における両側縁の位置が一致するように重ね合わせた状態で第1フィルム接合部20に供給されている。 The first film joining portion 20 is a device for joining the side portions of the original fabric of the film conveyed in the conveying direction MD along the conveying direction MD. As shown in FIG. 1, the first raw fabric 11 of the film conveyed in the conveying direction MD (hereinafter, this is also referred to as “first film original fabric 11”) and the original fabric 11 are conveyed in the same direction. The film has the same width as the second original fabric 12 (hereinafter, also referred to as "second film original fabric 12") of the film, and the positions of both side edges of both original fabrics 11 and 12 Are supplied to the first film joint 20 in a state of being overlapped so as to coincide with each other.

同図に示すように、両原反11,12は、これらの原反間に被包装物5が配された状態で、搬送ロール又はコンベアなどの搬送手段(図示せず)によって搬送され、第1フィルム接合部20に供給される。両原反11,12は、その両側縁の位置が一致するように重ね合わせた状態で搬送されながら第1フィルム接合部20を通過することで、両原反11,12の接合部位である各両側部が搬送方向MDに沿って連続的に接合され、第1接合部位15,15が形成される。両原反11,12が第1フィルム接合部20を通過したあとは、被包装物5は、搬送方向MDと直交する方向CD(以下、これを「幅方向CD」ともいう。)において、両原反11,12の両側部に形成された第1接合部位15,15の間に位置した状態で、原反とともに搬送される。第1フィルム接合部20における接合手段は、例えばヒートシール等を用いることができる。フィルムどうしの接合を効率良く行う観点から、同図に示すように、第1フィルム接合部20は、幅方向CDにおいて被包装物5の両側縁よりも外方に一対配されていることが好ましい。 As shown in the figure, the two raw fabrics 11 and 12 are transported by a transporting means (not shown) such as a transport roll or a conveyor with the object to be packaged 5 arranged between the raw fabrics. 1 It is supplied to the film joint 20. The two original fabrics 11 and 12 are the joint portions of the two original fabrics 11 and 12 by passing through the first film joint portion 20 while being conveyed in a state of being overlapped so that the positions of the both side edges coincide with each other. Both side portions are continuously joined along the transport direction MD, and the first joining portions 15 and 15 are formed. After the original fabrics 11 and 12 have passed through the first film joint 20, the object to be packaged 5 is placed in both CDs in the direction orthogonal to the transport direction MD (hereinafter, this is also referred to as “width direction CD”). It is transported together with the original fabric in a state of being located between the first joint portions 15 and 15 formed on both sides of the original fabrics 11 and 12. As the joining means in the first film joining portion 20, for example, a heat seal or the like can be used. From the viewpoint of efficiently bonding the films to each other, as shown in the figure, it is preferable that the first film bonding portions 20 are arranged in pairs outward from both side edges of the packaged object 5 in the width direction CD. ..

ノズル部30は、包装体内に封入される特定の気体を供給するためのものである。ノズル部30は、気体が流通可能な中空の部材であり、第1フィルム接合部20よりも搬送方向MDの上流側に位置するノズル部30の一端と、ノズル部30の他端である開口端31とを有する。ノズル部30は、その一端に接続された気体供給源(図示せず)から供給された気体流を、ノズル部30の他端である開口端31から外部に向けて連続的に又は断続的に供給できるようになっている。ノズル部30の開口端31は、第1フィルム接合部20よりも搬送方向MDの下流側に且つ第1接合部位15よりもCD方向内側に位置している。図1に示すノズル部30は、搬送方向MDに沿って延びるように配されているノズル延長部32を両原反11,12の間に一対有しており、これによって、気体流が両原反11,12の搬送方向MDに沿って供給される。各ノズル延長部32は、互いに略平行に配されている。またノズル部30におけるノズル延長部32は、幅方向CDにおいて、第1フィルム接合部20よりも内方に位置し、且つ搬送される被包装物5の両端縁よりも外方に配されている。同図に示すノズル部30は、第1フィルム接合部20よりも搬送方向上流側において、原反11,12の両側部の外方から内方に向けて折れ曲がる部位を有しており、これによって、両原反11,12の間にノズル延長部32が配されるようになっている。 The nozzle portion 30 is for supplying a specific gas to be sealed in the package. The nozzle portion 30 is a hollow member through which gas can flow, and has one end of the nozzle portion 30 located upstream of the first film joint portion 20 in the transport direction MD and an open end which is the other end of the nozzle portion 30. It has 31 and. The nozzle portion 30 continuously or intermittently directs a gas flow supplied from a gas supply source (not shown) connected to one end thereof toward the outside from an opening end 31 which is the other end of the nozzle portion 30. It can be supplied. The opening end 31 of the nozzle portion 30 is located downstream of the first film joint portion 20 in the transport direction MD and inside the first joint portion 15 in the CD direction. The nozzle portion 30 shown in FIG. 1 has a pair of nozzle extension portions 32 arranged so as to extend along the transport direction MD between the two original fabrics 11 and 12, thereby causing the gas flow to be both original. It is supplied along the transport direction MD of the anti-11 and 12. The nozzle extension portions 32 are arranged substantially parallel to each other. Further, the nozzle extension portion 32 of the nozzle portion 30 is located inward of the first film joint portion 20 in the width direction CD and is arranged outward of both end edges of the packaged object 5 to be transported. .. The nozzle portion 30 shown in the figure has a portion that bends from the outside to the inside of both side portions of the original fabrics 11 and 12 on the upstream side in the transport direction from the first film joint portion 20. , The nozzle extension portion 32 is arranged between the two original fabrics 11 and 12.

ノズル部30の配置位置の搬送方向MD下流側には、第2フィルム接合部40が配されている。第2フィルム接合部40は、第1フィルム接合部20を通過させて両側部どうしが接合された両原反11,12を、搬送方向MDと交差する方向に接合する装置である。同図に示す第2フィルム接合部40は、ヒートロールの態様となっており、第2フィルム接合部40を構成する二本のヒートロール間に被包装物5が位置する状態で、両原反11,12を搬送方向MDと交差する方向にわたって所定の間隔で接合することによって、被包装物5の周縁において両原反11,12が接合された包装体連続体1Aを形成することができる。第2フィルム接合部40における接合手段は、例えばヒートシール等を用いることができる。本実施形態における第2フィルム接合部40は二本のヒートロールとして示されているが、これに限られず、例えば、一本のヒートロールであってもよく、三本以上のヒートロールを用いてもよい。 A second film joining portion 40 is arranged on the downstream side of the MD in the transport direction at the arrangement position of the nozzle portion 30. The second film joining portion 40 is a device for joining both original fabrics 11 and 12 which have been joined to each other by passing through the first film joining portion 20 in a direction intersecting the transport direction MD. The second film joint 40 shown in the figure is in the form of a heat roll, and both original fabrics are in a state where the object to be packaged 5 is located between the two heat rolls constituting the second film joint 40. By joining 11 and 12 at predetermined intervals in a direction intersecting the transport direction MD, it is possible to form a package continuous body 1A in which both original fabrics 11 and 12 are joined at the peripheral edge of the object to be packaged 5. As the joining means in the second film joining portion 40, for example, a heat seal or the like can be used. The second film joint 40 in the present embodiment is shown as two heat rolls, but the present invention is not limited to this, and for example, one heat roll may be used, and three or more heat rolls are used. May be good.

詳細には、第2フィルム接合部40は、第1フィルム接合部20を通過させて両側部どうしが接合された両原反11,12を、搬送方向MDと交差する方向に接合して、幅方向CDの全域に延びる第2接合部位16,16を形成するものである。同図に示す第2フィルム接合部40は、ヒートロールの態様となっており、第2接合部位16を形成する前の状態では、第2フィルム接合部40は、両原反11,12における第1接合部位15以外の部位が離間した状態となるように配置されており、好ましくは第2フィルム接合部40と両原反11,12とはそれぞれ離間している。搬送方向MDに沿って配置された第2フィルム接合部40の間に被包装物5が位置する状態となったときに、第2フィルム接合部40を移動させる制御手段(図示せず)を介して、両原反11,12を当接させるように、第2フィルム接合部40を両原反11,12に押し当てて、両原反11,12を搬送方向MDと交差する方向に接合する。これによって、被包装物5の周縁外方に位置する両原反11,12どうしが、一対の第1接合部位15、15及び一対の第2接合部位16,16によって接合される。これによって、両接合部位15,16の内部に被包装物5及び気体が密封状態で封入された包装体連続体1Aを形成することができる。 Specifically, the second film joining portion 40 joins both original fabrics 11 and 12 which have been joined to each other by passing through the first film joining portion 20 in a direction intersecting the transport direction MD, and has a width. It forms the second junctions 16, 16 extending over the entire directional CD. The second film joint 40 shown in the figure is in the form of a heat roll, and in the state before forming the second joint 16, the second film joint 40 is the second in the original fabrics 11 and 12. The portions other than the first joint portion 15 are arranged so as to be separated from each other, and preferably the second film joint portion 40 and the original fabrics 11 and 12 are separated from each other. When the object to be packaged 5 is positioned between the second film joints 40 arranged along the transport direction MD, the second film joint 40 is moved via a control means (not shown). Then, the second film joining portion 40 is pressed against the two raw fabrics 11 and 12 so as to bring the two original fabrics 11 and 12 into contact with each other, and the two original fabrics 11 and 12 are joined in a direction intersecting the transport direction MD. .. As a result, the two original fabrics 11 and 12 located outside the peripheral edge of the object to be packaged 5 are joined by the pair of first joining parts 15 and 15 and the pair of second joining parts 16 and 16. As a result, the packaged continuous body 1A in which the object to be packaged 5 and the gas are sealed in a sealed state can be formed inside the joint portions 15 and 16.

第2フィルム接合部40の配置位置よりも搬送方向MD下流側には、カッター部50が配されている。カッター部50は、搬送方向MDに交差する方向に沿って延びるカッター刃を有しており、包装体連続体1Aにおける第2接合部位16の位置で両原反11,12を切断し、個々の包装体1に分断することができる。図1に示すカッター部50は、その軸方向と幅方向CDとが一致したカッターロールの態様となっており、該ロールの周上に配され、且つ該ロールの軸方向にわたって延びる第1カッター刃50aと、該ロールの周方向に沿って延びる第2カッター刃50bとを有している。カッターロールの回転によって、第1カッター刃50aは、包装体連続体1Aを第2接合部位16の位置で搬送方向MDに交差する方向にわたって切断する。これとともに、第2カッター刃50bは、包装体連続体1Aにおける幅方向CDの両端部側に一対配されているので、包装体連続体1Aを第1接合部位15の位置で搬送方向MDに沿って切断する。これによって、製品となる包装体1を形成することができる。 The cutter portion 50 is arranged on the side downstream of the MD in the transport direction from the arrangement position of the second film joint portion 40. The cutter portion 50 has a cutter blade extending along a direction intersecting the transport direction MD, cuts both original fabrics 11 and 12 at the position of the second joint portion 16 in the package continuum 1A, and individually. It can be divided into packages 1. The cutter portion 50 shown in FIG. 1 has a form of a cutter roll in which the axial direction and the width direction CD coincide with each other, and is a first cutter blade arranged on the circumference of the roll and extending in the axial direction of the roll. It has 50a and a second cutter blade 50b extending along the circumferential direction of the roll. By the rotation of the cutter roll, the first cutter blade 50a cuts the package continuous body 1A at the position of the second joint portion 16 in a direction intersecting the transport direction MD. At the same time, since the second cutter blades 50b are arranged in pairs on both ends of the width direction CD in the package continuum 1A, the package continuum 1A is placed along the transport direction MD at the position of the first joint portion 15. And disconnect. As a result, the package 1 as a product can be formed.

上述した製造装置10は、二枚のフィルム原反を用いて包装体1を製造する装置として説明したが、これに代えて、連続した一枚のフィルム原反を用いて包装体1を製造することもできる。詳細には、図2に示すように、一方向に搬送されている一枚のフィルム原反11Aを、該フィルム原反11Aの搬送方向MDに沿う両側部11a,11bを重ね合わせるように、該原反の幅方向CDの中央線Lを軸として二つ折りするか、又は搬送方向MDに沿う軸方向を有する筒状となるように形成する。被包装物5は、二つ折り又は筒状の原反の内側に配置しておく。この原反について、少なくとも両側部11a,11bを第1フィルム接合部20に通過させ、フィルム原反11Aの少なくとも両側部11a,11bを接合して、搬送方向MDに沿って延びる第1接合部位15を形成する。このとき、ノズル部30は、フィルム原反11Aの折り曲げ開始位置F1よりも搬送方向MDの上流側から挿入し、且つ開口端31が第1フィルム接合部20よりも搬送方向MDの下流に位置している状態で、第1フィルム接合部20の近傍の位置に且つ二つ折り又は筒状の原反の間に配しておく。一枚のフィルム原反11Aを筒状に形成する場合には、ノズル部30は、フィルム原反11Aを筒状に形成する位置よりも搬送方向MDの上流側から挿入しておけばよい。その後、上述した第2フィルム接合部40及びカッター部50を用いて、包装体1を形成することができる。図2に示す実施形態に関し、特に説明しない点については、先に述べた図1に示す実施形態に関する説明が適宜適用される。 The manufacturing apparatus 10 described above has been described as an apparatus for manufacturing the package 1 using two film raw fabrics, but instead of this, the packaging body 1 is manufactured using one continuous film raw fabric. You can also do it. Specifically, as shown in FIG. 2, a single film raw fabric 11A transported in one direction is overlapped with both side portions 11a and 11b along the transport direction MD of the film raw fabric 11A. It is folded in half with the center line L of the width direction CD of the original fabric as an axis, or formed so as to have a tubular shape having an axial direction along the transport direction MD. The object to be packaged 5 is placed inside a folded or tubular original fabric. For this raw fabric, at least both side portions 11a and 11b are passed through the first film joint portion 20, at least both side portions 11a and 11b of the film original fabric 11A are joined, and the first joint portion 15 extending along the transport direction MD. To form. At this time, the nozzle portion 30 is inserted from the upstream side of the transport direction MD from the bending start position F1 of the original film 11A, and the opening end 31 is located downstream of the first film joint portion 20 in the transport direction MD. In this state, it is arranged at a position near the first film joint 20 and between the folded or tubular raw fabrics. When forming one film raw fabric 11A into a tubular shape, the nozzle portion 30 may be inserted from the upstream side of the transport direction MD from the position where the film raw fabric 11A is formed into a tubular shape. After that, the package 1 can be formed by using the second film joining portion 40 and the cutter portion 50 described above. The description of the embodiment shown in FIG. 1 described above is appropriately applied to the points not particularly described with respect to the embodiment shown in FIG.

以上の構成を有する本発明の製造装置によれば、幅方向CDにおいて、ノズル部30が第1フィルム接合部20よりも内方に位置しており、且つノズル部30の開口端31が第1フィルム接合部20よりも搬送方向下流側に位置しているので、ノズル部30が両原反11,12の接合位置を規定するガイドの役割を果たし、両原反11,12どうしを所望の位置で搬送方向に沿って接合することができる。また、フィルムどうしの接合にあたり、ノズル部30によって被包装物5の動きが規制されるので、被包装物5が第1フィルム接合部20に意図せず巻き込まれたり、噛み込まれたりすることを防ぐことができる。その結果、被包装物5に傷がつくことなく、特定の気体が封入された包装体1を安定的に且つ連続的に製造することができる。これに加えて、ノズル部30が搬送方向MDに沿って、且つ第1フィルム接合部20の搬送方向下流まで延びるように配されているので、ノズル部30を搬送方向MDに交差する方向に挿入した場合と比較して、両原反11,12内の空気を、特定の気体に効率良く置換できるという利点も奏される。 According to the manufacturing apparatus of the present invention having the above configuration, in the width direction CD, the nozzle portion 30 is located inward of the first film joint portion 20, and the opening end 31 of the nozzle portion 30 is the first. Since the nozzle portion 30 is located downstream of the film joint portion 20 in the transport direction, the nozzle portion 30 serves as a guide for defining the joint positions of the two raw fabrics 11 and 12, and the two original fabrics 11 and 12 are positioned at a desired position. Can be joined along the transport direction. Further, when the films are joined to each other, the movement of the object to be packaged 5 is restricted by the nozzle portion 30, so that the object to be packaged 5 is unintentionally caught or bitten by the first film bonding portion 20. Can be prevented. As a result, the package 1 in which the specific gas is sealed can be stably and continuously manufactured without damaging the package 5. In addition to this, since the nozzle portion 30 is arranged so as to extend along the transport direction MD and to the downstream in the transport direction of the first film joint portion 20, the nozzle portion 30 is inserted in the direction intersecting the transport direction MD. There is also an advantage that the air in both original fabrics 11 and 12 can be efficiently replaced with a specific gas as compared with the case where.

このような効果を顕著なものとする観点から、図3に示すように、幅方向CDに沿う断面視において、被包装物5の側縁部と第1フィルム接合部20との幅方向CDに沿う間隔W1に対するノズル部30の外径W2の比(W2/W1)が、0.1以上であることが好ましく、0.15以上であることがより好ましく、0.2以上であることが更に好ましく、また、0.7以下であることが好ましく、0.6以下であることがより好ましく、0.5以下であることが更に好ましい。図3に示す実施形態では、被包装物5が複数枚積層された態様で配置されているが、この形態に限られず、例えば被包装物5が一枚のみ配置された態様であってもよい。 From the viewpoint of making such an effect remarkable, as shown in FIG. 3, in the cross-sectional view along the width direction CD, the width direction CD between the side edge portion of the object to be packaged 5 and the first film joint portion 20 The ratio (W2 / W1) of the outer diameter W2 of the nozzle portion 30 to the interval W1 along the line is preferably 0.1 or more, more preferably 0.15 or more, and further preferably 0.2 or more. It is preferable, and it is preferably 0.7 or less, more preferably 0.6 or less, and further preferably 0.5 or less. In the embodiment shown in FIG. 3, a plurality of objects to be packaged 5 are arranged in a laminated manner, but the present invention is not limited to this embodiment, and for example, only one packaged object 5 may be arranged. ..

同様の観点から、被包装物5の側縁部と第1フィルム接合部20との幅方向CDに沿う間隔W1(図3参照)は、好ましくは3mm以上、より好ましくは5mm以上、更に好ましくは7mm以上であり、好ましくは50mm以下、より好ましくは40mm以下、更に好ましくは30mm以下である。同様に、ノズル部30の外径W2(図3参照)は、好ましくは1mm以上、より好ましくは2mm以上、更に好ましくは3mm以上であり、好ましくは15mm以下、より好ましくは10mm以下、更に好ましくは6mm以下である。外径W2は、ノズル部30の延在方向と直交する断面において観察される外径とする。間隔W1及び外径W2が一定でない場合には、測定される距離のうち最短距離をそれぞれW1及びW2とする。 From the same viewpoint, the distance W1 (see FIG. 3) between the side edge portion of the object to be packaged 5 and the first film joint portion 20 along the widthwise CD is preferably 3 mm or more, more preferably 5 mm or more, still more preferably. It is 7 mm or more, preferably 50 mm or less, more preferably 40 mm or less, and further preferably 30 mm or less. Similarly, the outer diameter W2 (see FIG. 3) of the nozzle portion 30 is preferably 1 mm or more, more preferably 2 mm or more, still more preferably 3 mm or more, preferably 15 mm or less, more preferably 10 mm or less, still more preferably. It is 6 mm or less. The outer diameter W2 is the outer diameter observed in the cross section orthogonal to the extending direction of the nozzle portion 30. When the interval W1 and the outer diameter W2 are not constant, the shortest distance among the measured distances is W1 and W2, respectively.

本発明の製造装置によって製造される包装体1は、その内部に気体が封入された状態となっているところ、第2接合部位16が形成されるまでは、気体流がノズル部30を介して両原反11,12間に供給され続けている。ノズル部30の開口端31は、第1フィルム接合部20よりも搬送方向MDの下流側に位置しているので、両原反11,12の搬送によって開口端31及びその近傍を通過する被包装物5は、気体流の供給によって生じる外力や、搬送時に生じる原反のずれ等に起因して、フィルム原反に対する配置位置が意図せずずれてしまうことがある。その結果、被包装物5が所望の位置に配置された包装体1を首尾よく製造できないことがある。 The package 1 manufactured by the manufacturing apparatus of the present invention is in a state in which gas is sealed therein, and a gas flow passes through the nozzle portion 30 until the second joint portion 16 is formed. It continues to be supplied between the two original fabrics 11 and 12. Since the opening end 31 of the nozzle portion 30 is located downstream of the first film joint portion 20 in the transport direction MD, the package to be packaged passes through the opening end 31 and its vicinity by transporting both raw fabrics 11 and 12. The object 5 may be unintentionally displaced with respect to the film original fabric due to an external force generated by the supply of a gas flow, a deviation of the original fabric generated during transportation, or the like. As a result, the package 1 in which the object to be packaged 5 is arranged at a desired position may not be successfully manufactured.

この点に関して、気体流による外力や、原反のずれに起因した被包装物5の配置位置のずれを防止しつつ、両原反11,12並びに被包装物5の搬送を下流の工程へ安定的に行う観点から、少なくとも一方のフィルム原反と被包装物とをフィルム原反の外面から押圧する第1押圧部60が、ノズル部30における開口端31の近傍を含む位置に配されていることが好ましい。開口端31の近傍とは、開口端31の位置を基準として、搬送方向MDの上流側150mmから搬送方向MDの下流側150mmまでの範囲をいう。 In this regard, while preventing the displacement of the arrangement position of the packaged object 5 due to the external force due to the gas flow and the displacement of the original fabric, the transportation of the original fabrics 11 and 12 and the packaged object 5 is stabilized to the downstream process. The first pressing portion 60 that presses at least one of the film raw fabric and the object to be packaged from the outer surface of the film raw fabric is arranged at a position including the vicinity of the opening end 31 in the nozzle portion 30. Is preferable. The vicinity of the opening end 31 refers to a range from 150 mm on the upstream side of the transport direction MD to 150 mm on the downstream side of the transport direction MD with reference to the position of the open end 31.

図1に示す実施形態では、第1押圧部60はニップロールの態様であり、該ロールの軸方向と幅方向CDとを一致させて、幅方向CDの中央域に配されている。同図に示す第1押圧部60は、開口端31の位置を基準として、搬送方向MDの上流側と下流側とに複数本配されている。上述のように、各フィルム原反11,12がコンベアなどの搬送面を有する搬送手段(図示せず)によって搬送されている場合には、両原反11,12並びに被包装物5は、第1押圧部60と前記搬送手段との間を通過するように構成されている。また図4に示すように、第1押圧部60の配置位置を幅方向CDに沿って見たときに、第1押圧部60は、第1フィルム原反11の外面側から、第1フィルム原反11及び被包装物5をともに第2フィルム原反12側に押圧して、両原反11,12に対する被包装物5の配置位置を維持して搬送できるようになっている。第1押圧部60によって押圧されていない第1フィルム原反11の部位は、ノズル部30から供給された気体流によって、被包装物5から離間するように膨らんでいる。 In the embodiment shown in FIG. 1, the first pressing portion 60 is an aspect of a nip roll, and the axial direction and the width direction CD of the roll are aligned with each other and arranged in the central region of the width direction CD. A plurality of first pressing portions 60 shown in the figure are arranged on the upstream side and the downstream side of the transport direction MD with reference to the position of the opening end 31. As described above, when the film raw fabrics 11 and 12 are conveyed by a conveying means (not shown) having a conveying surface such as a conveyor, both raw fabrics 11 and 12 and the object to be packaged 5 are the first. 1 It is configured to pass between the pressing portion 60 and the conveying means. Further, as shown in FIG. 4, when the arrangement position of the first pressing portion 60 is viewed along the width direction CD, the first pressing portion 60 is the first film original from the outer surface side of the first film original fabric 11. Both the fabric 11 and the object to be packaged 5 are pressed toward the original fabric 12 of the second film so that the fabric 5 can be conveyed while maintaining the arrangement position of the object to be packaged 5 with respect to both the fabrics 11 and 12. The portion of the first film raw fabric 11 that is not pressed by the first pressing portion 60 is bulged so as to be separated from the object to be packaged 5 by the gas flow supplied from the nozzle portion 30.

上述のとおり、包装体1の製造過程において、第2接合部位16が形成されるまでの間は、気体流が両原反11,12間にノズル部30を介して供給され続けている。これによって、第1接合部位15,15が形成された両原反11,12は、供給された気体流によって過度に膨らむ状態となる場合がある。 As described above, in the manufacturing process of the package 1, the gas flow continues to be supplied through the nozzle portion 30 between the two original fabrics 11 and 12 until the second joint portion 16 is formed. As a result, the two original fabrics 11 and 12 on which the first joint portions 15 and 15 are formed may be in a state of being excessively swelled by the supplied gas flow.

この点に関して、気体流の供給による両原反11,12の過度な膨らみを防いで下流側に搬送しやすくするとともに、被包装物5の配置位置のずれを防いで、第2フィルム接合部40による両原反11,12どうしの接合を効率良く行う観点から、少なくとも一方のフィルム原反をその外面から押圧する第2押圧部70が、搬送方向MDにおける第1フィルム接合部20の配置位置から第2フィルム接合部40の配置位置までの間に配されていることが好ましい。この第2押圧部70は、被包装物5が存在する位置において、フィルム原反を押圧するが、被包装物5を押圧しないように配されていることも好ましい。 In this regard, the second film joint 40 is prevented from excessively swelling of the original fabrics 11 and 12 due to the supply of the gas flow to facilitate transportation to the downstream side, and also to prevent the arrangement position of the packaged object 5 from being displaced. From the viewpoint of efficiently joining the two raw fabrics 11 and 12 together, the second pressing portion 70 that presses at least one of the original fabrics from the outer surface is from the arrangement position of the first film joint portion 20 in the transport direction MD. It is preferable that the second film joint portion 40 is arranged up to the arrangement position. The second pressing portion 70 presses the film raw fabric at the position where the object to be packaged 5 exists, but it is also preferable that the second pressing portion 70 is arranged so as not to press the object to be packaged 5.

図1に示す実施形態では、第2押圧部70はニップロールの態様であり、該ロールの軸方向と幅方向CDとを一致させた状態で、幅方向CDの全域にわたって配されている。同図に示す第2押圧部70は、第1フィルム接合部20の搬送方向MDの下流側且つ第2フィルム接合部40の搬送方向MDの上流側に複数本配されている。また図5に示すように、第2押圧部70の配置位置を幅方向CDに沿って見たときに、第2押圧部70は、第1フィルム原反11の外面側から、第1フィルム原反11のみを第2フィルム原反12側に押圧して、両原反11,12を搬送できるようになっている。つまり、本実施形態における第2押圧部70による押圧は、第1フィルム原反11と被包装物5とが互いに離間した状態となるように制御されて行われる。本発明の効果が奏される限りにおいて、両フィルム原反11,12と被包装物5とが互いに接触するように、第2押圧部70によって押圧されていてもよい。本実施形態における第2押圧部70は、ニップロールの態様として説明したが、本発明の効果が奏される限りにおいて、ニップロールに代えて、又はこれに加えて、第2押圧部70としてコンベアやプレートを適用してもよい。同様に、第2押圧部70に対向配置され、各フィルム原反11,12を搬送する搬送手段(図示せず)は、ロール、コンベア、プレート等で構成することができる。 In the embodiment shown in FIG. 1, the second pressing portion 70 is in the form of a nip roll, and is arranged over the entire width direction CD in a state where the axial direction and the width direction CD of the roll are matched. A plurality of the second pressing portions 70 shown in the figure are arranged on the downstream side of the transport direction MD of the first film joint portion 20 and on the upstream side of the transport direction MD of the second film joint portion 40. Further, as shown in FIG. 5, when the arrangement position of the second pressing portion 70 is viewed along the width direction CD, the second pressing portion 70 is the first film original from the outer surface side of the first film original fabric 11. By pressing only the fabric 11 toward the second film original fabric 12, both original fabrics 11 and 12 can be conveyed. That is, the pressing by the second pressing portion 70 in the present embodiment is controlled so that the first film original fabric 11 and the object to be packaged 5 are separated from each other. As long as the effects of the present invention are exhibited, the original fabrics 11 and 12 of both films and the object to be packaged 5 may be pressed by the second pressing portion 70 so as to come into contact with each other. The second pressing portion 70 in the present embodiment has been described as an aspect of the nip roll, but as long as the effect of the present invention is exhibited, the second pressing portion 70 may be replaced with or in addition to the nip roll, and the conveyor or plate may be used as the second pressing portion 70. May be applied. Similarly, the transport means (not shown) that is arranged to face the second pressing portion 70 and conveys the original films 11 and 12 can be composed of a roll, a conveyor, a plate, or the like.

特に、両原反11,12間での気体の置換状態を維持しつつ、第2フィルム接合部40による両原反11,12どうしの接合を首尾よく行う観点から、被包装物5の厚さH1に対する第2押圧部70のクリアランスH2の比(H2/H1)は、0.7以上であることが好ましく、1以上であることがより好ましく、1.5以上であることが更に好ましく、また、5以下であることが好ましく、3.5以下であることがより好ましく、2以下であることが更に好ましい。クリアランスH2とは、1つの第2押圧部70に着目したときに、第2押圧部70に接触している原反の面と、第2押圧部70から最も遠い側の原反の外面との最短距離を指す。図5に示す実施態様では、第2押圧部70が一つ配されており、その第2押圧部70の周面と第1フィルム原反11の外面とが接触しているので、第2押圧部70の周面と第2フィルム原反12の外面との最短距離を実質的にクリアランスH2とすることができる。 In particular, the thickness of the object to be packaged 5 is from the viewpoint of successfully joining the two raw fabrics 11 and 12 by the second film bonding portion 40 while maintaining the gas replacement state between the two raw fabrics 11 and 12. The ratio (H2 / H1) of the clearance H2 of the second pressing portion 70 to H1 is preferably 0.7 or more, more preferably 1 or more, further preferably 1.5 or more, and further. It is preferably 5 or less, more preferably 3.5 or less, and even more preferably 2 or less. The clearance H2 refers to the surface of the original fabric that is in contact with the second pressing portion 70 and the outer surface of the original fabric that is farthest from the second pressing portion 70 when focusing on one second pressing portion 70. Refers to the shortest distance. In the embodiment shown in FIG. 5, one second pressing portion 70 is arranged, and the peripheral surface of the second pressing portion 70 is in contact with the outer surface of the first film original fabric 11, so that the second pressing portion 70 is in contact with the outer surface. The shortest distance between the peripheral surface of the portion 70 and the outer surface of the second film original fabric 12 can be substantially defined as the clearance H2.

同様の観点から、被包装物5の無荷重状態での厚さH1(図5参照)は、好ましくは0.5mm以上、より好ましくは1mm以上、更に好ましくは1.5mm以上であり、好ましくは20mm以下、より好ましくは15mm以下、更に好ましくは10mm以下である。図5に示すように、被包装物5が複数枚積層されている場合には、それらの無荷重状態での厚みを合計した合計厚みを厚みH1とする。 From the same viewpoint, the thickness H1 (see FIG. 5) of the object to be packaged 5 under no load is preferably 0.5 mm or more, more preferably 1 mm or more, still more preferably 1.5 mm or more, and preferably 1.5 mm or more. It is 20 mm or less, more preferably 15 mm or less, still more preferably 10 mm or less. As shown in FIG. 5, when a plurality of objects to be packaged 5 are laminated, the total thickness obtained by adding the thicknesses of the objects to be packaged 5 in a no-load state is defined as the thickness H1.

同様に、第2押圧部70のクリアランスH2(図5参照)は、好ましくは1mm以上、より好ましくは2mm以上、更に好ましくは3mm以上であり、好ましくは30mm以下、より好ましくは20mm以下、更に好ましくは10mm以下である。図5に示すクリアランスH2は、上述のとおり、第2押圧部70の周面と、第2フィルム原反12の外面との距離として示しているが、例えば、コンベア等の搬送面(図示せず)上に第2フィルム原反12が載置されて搬送される場合には、搬送面と第2フィルム原反12の外面とは互いに接しているので、搬送面と第2押圧部70の周面との最短距離を実質的にクリアランスH2とすることができる。また、第2押圧部70をシート厚み方向に配された一対のニップロールとする場合には、一対のニップロールの間に第1及び第2フィルム原反11,12が導入され、両原反11,12と各ニップロールとはそれぞれ接する状態で搬送されるので、ニップロールどうしの周面間の最短距離をクリアランスH2とすることができる。 Similarly, the clearance H2 (see FIG. 5) of the second pressing portion 70 is preferably 1 mm or more, more preferably 2 mm or more, still more preferably 3 mm or more, preferably 30 mm or less, more preferably 20 mm or less, still more preferably. Is 10 mm or less. As described above, the clearance H2 shown in FIG. 5 is shown as the distance between the peripheral surface of the second pressing portion 70 and the outer surface of the second film original fabric 12, but for example, a transport surface of a conveyor or the like (not shown). ) When the second film original fabric 12 is placed and conveyed, the conveying surface and the outer surface of the second film original fabric 12 are in contact with each other, so that the conveying surface and the circumference of the second pressing portion 70 are in contact with each other. The shortest distance to the surface can be substantially the clearance H2. Further, when the second pressing portion 70 is a pair of nip rolls arranged in the sheet thickness direction, the first and second film raw fabrics 11 and 12 are introduced between the pair of nip rolls, and both raw fabrics 11 and 12 are introduced. Since the 12 and each nip roll are conveyed in contact with each other, the shortest distance between the peripheral surfaces of the nip rolls can be set as the clearance H2.

カッター部50において包装体連続体1Aを分断する際に、カッター刃の包装体連続体1Aへの押し当てに起因した両原反11,12の意図しない位置ずれを防止して、所望の位置での分断を首尾よく行う観点から、少なくとも一方の原反をその外面から押圧する第3押圧部80が、搬送方向MDにおける第2フィルム接合部40の配置位置からカッター部50の配置位置までの間に配されていることが好ましく、カッター部50の配置位置側に配されていることがより好ましい。このような構成を有することで、第3押圧部80によって包装体連続体1Aを押圧しながらカッター部50による分断を行うことができ、その結果、目的とする寸法を有する包装体1を連続的に製造することができる。 When the package continuum 1A is divided by the cutter portion 50, the unintentional misalignment of the two original fabrics 11 and 12 due to the pressing of the cutter blade against the package continuum 1A is prevented, and the position is desired. From the viewpoint of successfully dividing the film, the third pressing portion 80 that presses at least one of the original fabrics from its outer surface is between the arrangement position of the second film joint portion 40 and the arrangement position of the cutter portion 50 in the transport direction MD. It is more preferable that the cutter portion 50 is arranged on the side where the cutter portion 50 is arranged. With such a configuration, the packaging body 1A can be divided by the cutter unit 50 while being pressed by the third pressing unit 80, and as a result, the packaging body 1 having the target size can be continuously formed. Can be manufactured in.

図1に示す実施形態では、第3押圧部80はニップロールの態様であり、該ロールの軸方向と幅方向CDとを一致させた状態で、幅方向CDにおける両原反11,12の両端部を押圧できるように配されている。同図に示す第3押圧部80は、第2フィルム接合部40の配置位置よりも下流側の遠方に位置し、且つカッター部50の配置位置よりも上流側且つカッター部50の近傍に配されている。第3押圧部80における押圧態様は、第1フィルム原反11のみを第2フィルム原反12側に押圧していてもよく、第1フィルム原反11及び被包装物5をともに押圧していてもよい。 In the embodiment shown in FIG. 1, the third pressing portion 80 is an aspect of a nip roll, and both ends of both original fabrics 11 and 12 in the width direction CD in a state where the axial direction and the width direction CD of the roll are matched. It is arranged so that it can be pressed. The third pressing portion 80 shown in the figure is located far on the downstream side of the arrangement position of the second film joint portion 40, and is arranged on the upstream side of the arrangement position of the cutter portion 50 and in the vicinity of the cutter portion 50. ing.

以上は、包装体1の製造に好適に用いられる製造装置10に関する説明であったところ、包装体1の好適な製造方法を、図1に示す製造装置10を用いた場合を例にとり説明する。 The above is the description of the manufacturing apparatus 10 preferably used for manufacturing the package 1, and the preferred manufacturing method of the package 1 will be described by taking the case where the manufacturing apparatus 10 shown in FIG. 1 is used as an example.

まず、被包装物5を第1フィルム原反11と、第2フィルム原反12との間に配置する。被包装物5の配置方法としては、例えば、搬送方向MDに搬送されている第2フィルム原反12上に被包装物5を配置し、その後、第1フィルム原反11を搬送方向MDに搬送しながら積層する方法が挙げられる。図1に示す実施形態では、被包装物5は、その長手方向を幅方向CDと一致させて配されている。 First, the object to be packaged 5 is placed between the first film raw fabric 11 and the second film raw fabric 12. As a method of arranging the object to be packaged 5, for example, the object to be packaged 5 is arranged on the second film raw fabric 12 transported in the transport direction MD, and then the first film raw fabric 11 is transported to the transport direction MD. There is a method of laminating while doing so. In the embodiment shown in FIG. 1, the packaged object 5 is arranged so that its longitudinal direction coincides with the width direction CD.

次に、特定の気体流をノズル部30から両原反11,12間に供給した状態で、同一の方向に搬送され且つ重ね合わせた両原反11,12を搬送方向MDに沿う両側部どうしで接合して、第1接合部位15を形成する第1接合工程を行う。製造装置10を用いた場合の第1接合工程は、重ね合わせた両原反11,12の両側部を第1フィルム接合部20に通過させることによって行われる。第1フィルム接合部20に両原反11,12を重ね合わせた状態で通過させることによって、両原反11,12の両側部に、搬送方向MDに沿って延びる一対の第1接合部位15が連続的に形成される。これとともに、搬送方向MDに沿って延びるノズル部30から気体流が供給されて、両原反11,12内の空気が、供給された特定の気体に置換される。 Next, in a state where a specific gas flow is supplied from the nozzle portion 30 between the two raw fabrics 11 and 12, the two original fabrics 11 and 12 that are conveyed in the same direction and overlapped are placed on both sides along the conveying direction MD. The first joining step of forming the first joining portion 15 is performed. The first joining step when the manufacturing apparatus 10 is used is performed by passing both side portions of the overlapped original fabrics 11 and 12 through the first film joining portion 20. By passing the original fabrics 11 and 12 through the first film joint portion 20 in a superposed state, a pair of first joint portions 15 extending along the transport direction MD are formed on both side portions of the original fabrics 11 and 12. It is formed continuously. At the same time, a gas flow is supplied from the nozzle portion 30 extending along the transport direction MD, and the air in both original fabrics 11 and 12 is replaced with the supplied specific gas.

ノズル部30から供給される気体の種類は、窒素、ヘリウム、アルゴン、二酸化炭素等の不活性ガスが好ましく用いられる。これらのガスは、包装体1及びその内容物である被包装物5の組成や物性、仕様に応じて適宜選択して用いることができる。 As the type of gas supplied from the nozzle unit 30, an inert gas such as nitrogen, helium, argon or carbon dioxide is preferably used. These gases can be appropriately selected and used according to the composition, physical properties, and specifications of the package 1 and the packaged object 5 which is the content thereof.

供給される気体流による特定の気体への置換効率の向上と、被包装物5の位置ずれを防いで、包装体1の安定的な生産とを両立させる観点から、各ノズル部30から供給される気体流の流量は、それぞれ独立して、好ましくは2L/min以上、更に好ましくは4L/min以上であり、また、好ましくは30L/min以下、更に好ましくは20L/min以下である。同様の観点から、各ノズル部30から供給される気体流の流速は、それぞれ独立して、好ましくは5m/s以上、更に好ましくは10m/s以上であり、また、好ましくは40m/s以下、更に好ましくは30m/s以下である。気体流の流量及び流速は、各ノズル部30における開口端31での値とする。気体流の流量及び流速は、例えば、気体供給源から供給される気体流の流量及び圧力を変更したり、あるいは、ノズル部30の外径が上述の条件を満たすことを条件として、ノズル部30の内径を変更したりすることによって適宜調整することができる。 It is supplied from each nozzle portion 30 from the viewpoint of improving the efficiency of replacement with a specific gas by the supplied gas flow, preventing the displacement of the object to be packaged 5, and achieving stable production of the package 1. The flow rates of the gas streams are independently, preferably 2 L / min or more, more preferably 4 L / min or more, and preferably 30 L / min or less, further preferably 20 L / min or less. From the same viewpoint, the flow velocity of the gas flow supplied from each nozzle portion 30 is independently, preferably 5 m / s or more, more preferably 10 m / s or more, and preferably 40 m / s or less. More preferably, it is 30 m / s or less. The flow rate and flow velocity of the gas flow are values at the opening end 31 of each nozzle portion 30. The flow rate and flow velocity of the gas flow are determined, for example, on the condition that the flow rate and pressure of the gas flow supplied from the gas supply source are changed, or the outer diameter of the nozzle portion 30 satisfies the above conditions. It can be adjusted as appropriate by changing the inner diameter of the gas.

第1接合工程の実施においては、第1接合工程の直前若しくは直後、又は同時に、少なくとも一方の原反及び被包装物5を原反の外部から押圧して、原反11,12に対する被包装物5の配置位置を維持した状態で搬送する工程(第1押圧工程)を行うことが好ましい。直前とは第1接合工程よりも搬送方向上流のことを示し、直後とは第1接合工程よりも搬送方向下流のことを示す。製造装置10を用いた場合の第1押圧工程は、例えば、ロール状の第1押圧部60をロールの軸方向と幅方向CDとを一致させた状態で配し、この第1押圧部60を用いて、第1フィルム原反11の外面から、第1フィルム原反11及び被包装物5をともに押圧した状態で、下流の工程に搬送する。これによって、気体流の供給に起因した被包装物5の意図しない位置ずれを防ぎながら、原反11,12及び被包装物5を搬送することができ、下流の工程を安定的に行うことができる。第1押圧工程における「原反及び被包装物5を原反の外部から押圧する」とは、少なくとも一方のフィルム原反と被包装物5とが、これらの塑性変形や破断を生じない外力で押圧されている状態をいう。 In the implementation of the first joining step, at least one of the raw fabric and the object to be packaged 5 is pressed from the outside of the original fabric immediately before, immediately after, or at the same time as the first joining step, and the material to be packaged against the original fabrics 11 and 12. It is preferable to carry out the step of transporting while maintaining the arrangement position of 5 (first pressing step). Immediately before means upstream in the transport direction from the first joining step, and immediately after means downstream from the first joining step in the transport direction. In the first pressing step when the manufacturing apparatus 10 is used, for example, the roll-shaped first pressing portion 60 is arranged in a state where the axial direction of the roll and the width direction CD are aligned, and the first pressing portion 60 is arranged. In use, the first film raw fabric 11 and the object to be packaged 5 are both pressed from the outer surface of the first film raw fabric 11 and conveyed to a downstream process. As a result, the raw fabrics 11 and 12 and the packaged object 5 can be conveyed while preventing the unintended misalignment of the packaged object 5 due to the supply of the gas flow, and the downstream process can be stably performed. it can. "Pressing the original fabric and the object to be packaged 5 from the outside of the original fabric" in the first pressing step means that at least one of the original film material and the object to be packaged 5 is subjected to an external force that does not cause plastic deformation or breakage. The state of being pressed.

続いて、両原反11,12を、搬送方向MDと交差する方向に、好ましくは搬送方向MDと直交する方向に接合して、被包装物5及び気体が封入された包装体連続体1Aを形成する第2接合工程を行う。本接合工程においても、ノズル部30からの気体流の供給は行われている。 Subsequently, the two original fabrics 11 and 12 are joined in a direction intersecting the transport direction MD, preferably in a direction orthogonal to the transport direction MD, to form a packaged continuous body 1A in which the object to be packaged 5 and the gas are sealed. The second joining step of forming is performed. Also in this joining step, the gas flow is supplied from the nozzle portion 30.

製造装置10を用いた場合の第2接合工程は、第2フィルム接合部40を、その搬送方向MDに沿う間隔が被包装物5の搬送方向MDに沿う長さよりも広くなるように複数配置した状態で、搬送方向MDに沿って隣り合う第2フィルム接合部40の間に被包装物5が搬送されたときに、第2フィルム接合部40による接合を行って、搬送方向MDと直交する方向に延びる第2接合部位16,16を幅方向CDにわたって形成する。このような第2接合部位16,16が形成されると、被包装物5の周縁外方に位置する両原反11,12どうしが、一対の第1接合部位15、15及び一対の第2接合部位16,16によって接合されるので、被包装物5は置換された気体とともに密封状態で封入される。両原反11,12は、第2フィルム接合部40による接合が行われたあとも切断されていないので、被包装物5及び置換された気体が両原反11,12内に所定の間隔で封入された包装体連続体1Aとなって、下流の工程へ搬送される。 In the second bonding step when the manufacturing apparatus 10 is used, a plurality of second film bonding portions 40 are arranged so that the interval along the transport direction MD is wider than the length along the transport direction MD of the packaged object 5. In this state, when the object to be packaged 5 is transported between the second film bonding portions 40 adjacent to each other along the transport direction MD, the packaged object 5 is bonded by the second film bonding portion 40 in a direction orthogonal to the transport direction MD. The second joint sites 16 and 16 extending to the width direction CD are formed. When such second joint portions 16 and 16 are formed, the two original fabrics 11 and 12 located outside the peripheral edge of the object to be packaged 5 form a pair of first joint portions 15 and 15 and a pair of second joint portions 15. Since the objects to be packaged 5 are joined by the joining sites 16 and 16, the packaged object 5 is sealed together with the replaced gas. Since the original fabrics 11 and 12 have not been cut even after being joined by the second film bonding portion 40, the object to be packaged 5 and the replaced gas are placed in the original fabrics 11 and 12 at predetermined intervals. It becomes a sealed package continuous body 1A and is transported to a downstream process.

第2接合工程による接合をより安定的に行う観点から、被包装物5を押圧しない状態で、少なくとも一方の原反をその外面から押圧して搬送する工程(第2押圧工程)を、第1接合工程を行った後で且つ第2接合工程よりも前に行うことが好ましく、第1押圧部60による第1押圧工程を行った後で且つ第2接合工程よりも前に行うことがより好ましい。第2接合工程における「被包装物5を押圧しない」とは、押圧されている少なくとも一方のフィルム原反と被包装物5とが離間した状態となっているか、又は、押圧されている少なくとも一方のフィルム原反が被包装物5と接触しているが、被包装物5には、原反の押圧によって被包装物5が損傷する大きさの外力が負荷されていないことをいう。いずれの場合であっても、第2押圧工程における被包装物5は、外力による塑性変形や破断を生じない状態で搬送されているので、被包装物5は、接合時における寸法や形状を維持したままとなっている。 From the viewpoint of more stable joining by the second joining step, the first step (second pressing step) is to press and transport at least one of the raw fabrics from the outer surface without pressing the object to be packaged 5. It is preferable to carry out after the joining step and before the second joining step, and more preferably after the first pressing step by the first pressing portion 60 and before the second joining step. .. "Do not press the object to be packaged 5" in the second joining step means that at least one of the film raw fabrics to be pressed and the object to be packaged 5 are separated from each other, or at least one of them is pressed. The original film of the film is in contact with the object to be packaged 5, but the object to be packaged 5 is not loaded with an external force large enough to damage the object to be packaged 5 due to the pressing of the film. In any case, since the packaged object 5 in the second pressing step is transported in a state where plastic deformation or breakage due to an external force does not occur, the packaged object 5 maintains the dimensions and shape at the time of joining. It remains as it is.

製造装置10を用いた場合の第2押圧工程は、幅方向CDの全域にわたって配されているロール状の第2押圧部70を、ロールの軸方向と幅方向CDとを一致させた状態で複数配して、被包装物5が存在する位置において、第1フィルム原反11の外面側から、第1フィルム原反11のみを第1フィルム原反11と被包装物5とが互いに離間した状態となるように押圧しながら、両原反11,12を第2フィルム接合部40に搬送する。このように搬送することで、気体流の供給による両原反11,12の過度な膨らみを防いで下流側に搬送しやすくするとともに、被包装物5の損傷と被包装物5の配置位置のずれとを効果的に防ぐことができる。特に、第1押圧工程及び第2押圧工程をこの順で行うことで、気体流の供給によって生じ得る開口端31近傍での被包装物5の配置位置のずれを第1押圧工程によって防ぎながら搬送するとともに、両原反11,12の過度な膨らみによって生じ得る被包装物5の配置位置のずれを第2押圧工程によって防ぐことができるので、包装体1を高い生産効率で一層安定的に製造できる点で有利となる。本発明の効果が奏される限りにおいて、第2押圧部70による押圧は、被包装物5の損傷が生じない外力を付与して、各フィルム原反11,12と被包装物5が接触するように行われていてもよい。 In the second pressing step when the manufacturing apparatus 10 is used, a plurality of roll-shaped second pressing portions 70 arranged over the entire width direction CD are arranged in a state where the axial direction of the roll and the width direction CD are matched. Arranged, at the position where the object to be packaged 5 exists, only the first film original fabric 11 is separated from the outer surface side of the first film original fabric 11 and the packaged object 5 from each other. Both original fabrics 11 and 12 are conveyed to the second film joint 40 while being pressed so as to be. By transporting in this way, it is possible to prevent excessive swelling of the two original fabrics 11 and 12 due to the supply of the gas flow and facilitate the transport to the downstream side, and also to damage the packaged object 5 and position the packaged object 5. It is possible to effectively prevent deviation. In particular, by performing the first pressing step and the second pressing step in this order, the first pressing step prevents the displacement of the arrangement position of the object to be packaged 5 in the vicinity of the opening end 31 which may occur due to the supply of the gas flow, and is conveyed. At the same time, the second pressing step can prevent the displacement of the arrangement position of the object to be packaged 5 which may be caused by the excessive swelling of the original fabrics 11 and 12, so that the package 1 can be manufactured more stably with high production efficiency. It is advantageous in that it can be done. As long as the effect of the present invention is exhibited, the pressing by the second pressing portion 70 applies an external force that does not cause damage to the object to be packaged 5, and the film raw fabrics 11 and 12 come into contact with the object to be packaged 5. It may be done as follows.

最後に、包装体連続体1Aを、第2接合工程によって両原反11,12が接合された第2接合部位16で、前記搬送方向と交差する方向にわたって切断して、包装体1を形成する切断工程を行う。製造装置10を用いた場合の切断工程では、軸方向と幅方向CDとが一致したカッターロールをカッター部50として用いて、第1カッター刃50aと第2接合部位16とを一致させるようにロールを回転して、第2接合部位16の位置で幅方向CDに沿って包装体連続体1Aを切断する。これとともに、第2カッター刃50bによって、第1接合部位15の位置で搬送方向MDに沿って、包装体連続体1Aにおける両原反11,12の幅方向CDの両側縁を切断し、トリミング加工する。これによって、包装体連続体1Aが個々に分断された包装体1を連続的に製造することができる。 Finally, the package continuous body 1A is cut at the second joint portion 16 where the original fabrics 11 and 12 are joined by the second joining step in a direction intersecting the transport direction to form the package 1. Perform the cutting process. In the cutting step when the manufacturing apparatus 10 is used, a cutter roll in which the axial direction and the width direction CD coincide with each other is used as the cutter portion 50, and the roll is made so that the first cutter blade 50a and the second joint portion 16 are aligned with each other. Is rotated to cut the package continuum 1A along the width direction CD at the position of the second joint portion 16. At the same time, the second cutter blade 50b cuts both side edges of the widthwise CDs 11 and 12 of the packaging continuous body 1A along the transport direction MD at the position of the first joint portion 15 and trimming. To do. Thereby, the package body 1 in which the package body continuous body 1A is individually divided can be continuously produced.

カッター刃の包装体連続体1Aへの押し当てや製造装置の振動に起因した両原反11,12の意図しない位置ずれを防止して、所望の位置での分断を首尾よく行う観点から、切断工程においては、包装体連続体1Aを押圧した状態で切断する工程(第3押圧工程)を行うことが好ましい。製造装置10を用いた場合の切断工程における押圧は、幅方向CDにおける両原反11,12の両端部を押圧可能なロール状の第3押圧部80を用いて押圧した状態でカッター部50へ搬送し、切断する。 Cutting from the viewpoint of preventing unintentional misalignment of the two original fabrics 11 and 12 due to pressing of the cutter blade against the package continuous body 1A and vibration of the manufacturing equipment and successfully dividing at the desired position. In the step, it is preferable to perform a step of cutting the package continuous body 1A in a pressed state (third pressing step). When the manufacturing apparatus 10 is used, the pressing in the cutting step is performed on the cutter portion 50 in a state where both ends of the original fabrics 11 and 12 in the width direction CD are pressed by the roll-shaped third pressing portion 80 that can be pressed. Transport and cut.

上述した製造方法は、二枚のフィルム原反を用いて包装体1を製造する実施形態として説明したが、これに代えて、連続した一枚のフィルム原反を用いて包装体1を製造することもできる。詳細には、一枚のフィルム原反上に被包装物5を配した状態で、該原反の幅方向CDの中央線を軸として二つ折りするか、又は搬送方向に沿う軸方向を有する筒状となるように形成する。このとき、原反の幅方向CDにおける両側部を重ね合わせた状態で搬送することが好ましい。そして、ノズル部30から該原反の内側に気体を供給した状態で、該原反の搬送方向に沿う両側部を重ね合わせて接合する第1接合工程を行う。本実施形態における第1接合工程は、例えば第1フィルム接合部20を用いて行うことができる。その後、上述した実施形態と同様に、第2接合工程及び切断工程、並びに必要に応じて第1ないし第3押圧工程を行う。 The above-mentioned manufacturing method has been described as an embodiment of manufacturing the package 1 using two film raw fabrics, but instead of this, the packaging body 1 is manufactured using one continuous film raw fabric. You can also do it. Specifically, in a state where the object to be packaged 5 is arranged on one film raw fabric, it is folded in half with the center line of the width direction CD of the raw fabric as an axis, or a cylinder having an axial direction along the transport direction. It is formed so as to have a shape. At this time, it is preferable to carry the original fabric in a state where both side portions in the width direction CD are overlapped. Then, in a state where gas is supplied from the nozzle portion 30 to the inside of the raw fabric, the first joining step of superimposing and joining both side portions along the transport direction of the raw fabric is performed. The first bonding step in the present embodiment can be performed using, for example, the first film bonding portion 20. After that, the second joining step and the cutting step, and if necessary, the first to third pressing steps are performed in the same manner as in the above-described embodiment.

以上の工程を経て、被包装物5がフィルムで包装された包装体1を製造することができる。この包装体1は、その内部に、被包装物5及び置換された特定の気体が密封状態で封入されているものである。密封状態とは、固体、液体及び気体の全てが包装体1の内部に流入せず、且つ包装体1の外部に流出しない態様を指す。 Through the above steps, a package 1 in which the object to be packaged 5 is packaged with a film can be manufactured. The package 1 is one in which the object to be packaged 5 and the replaced specific gas are sealed in a sealed state. The sealed state refers to a mode in which all of the solid, liquid, and gas do not flow into the inside of the package 1 and do not flow out of the package 1.

本発明に用いられるフィルム及びその原反は、置換された特定の気体及び外気を透過しない任意の材料を用いることができる。このような材料としては、例えばアルミ箔、熱可塑性樹脂フィルム、あるいは熱可塑性樹脂フィルムにアルミニウムなどの金属薄膜をラミネートしたもの等を用いることができる。 As the film and its raw material used in the present invention, a specific substituted gas and any material that does not allow the outside air to permeate can be used. As such a material, for example, an aluminum foil, a thermoplastic resin film, or a material obtained by laminating a metal thin film such as aluminum on a thermoplastic resin film can be used.

以上、本発明をその好ましい実施形態に基づき説明したが、本発明は前記実施形態に制限されない。例えば、第1押圧部60及び第2押圧部70は、それぞれ複数配された態様となっているが、本発明の効果が奏される限りにおいて、それぞれ単独で配置してもよい。また、第3押圧部80は単独で配された態様となっているが、本発明の効果が奏される限りにおいて、複数配置してもよい。 Although the present invention has been described above based on the preferred embodiment, the present invention is not limited to the above embodiment. For example, the first pressing portion 60 and the second pressing portion 70 are arranged in a plurality of positions, respectively, but they may be arranged independently as long as the effects of the present invention are exhibited. Further, although the third pressing portion 80 is arranged independently, a plurality of third pressing portions 80 may be arranged as long as the effect of the present invention is exhibited.
