Description

本発明は、合成樹脂材にて形成されるガゼット袋の製造方法及び製造装置に係り、自動製袋機でガゼット袋を2個取りすることができる合成樹脂製ガゼット袋の製造方法及び製造装置に関する。   The present invention relates to a manufacturing method and a manufacturing apparatus for a gusset bag formed of a synthetic resin material, and relates to a manufacturing method and a manufacturing apparatus for a synthetic resin gusset bag capable of taking two gusset bags with an automatic bag-making machine. .

合成樹脂製のガゼット袋を製造する方法や装置として、例えば特許文献1および特許文献2に記載の技術が提案されている。   As a method and an apparatus for manufacturing a synthetic resin gusset bag, for example, techniques described in Patent Document 1 and Patent Document 2 have been proposed.

特許文献1に記載の製造方法は、横マチ部を構成する横マチ成形材を前後面のフィルムの間に介在し、更に底部を構成する別個の底フィルムを前後面のフィルムの搬送方向に対して平行に搬送しながらフィルムを溶着してガゼット袋を製造する方法である。   In the manufacturing method described in Patent Document 1, the horizontal gusset forming material constituting the horizontal gusset portion is interposed between the front and back films, and a separate bottom film constituting the bottom portion is further provided with respect to the transport direction of the front and back films. The film is welded while being conveyed in parallel to produce a gusset bag.

一方、特許文献2に記載されたガゼット袋を製造する製袋機は胴部を構成する帯状のフィルムの一部を二つ折り状に折り込み、これを底部に導いて角底を製造する装置である。   On the other hand, a bag making machine for producing a gusset bag described in Patent Document 2 is an apparatus for producing a square bottom by folding a part of a belt-like film constituting a body part into two folds and guiding it to the bottom part. .

特許第4436521号公報Japanese Patent No. 4436521 特許第3655627号公報Japanese Patent No. 3655627

このような従来のガゼット袋の製造方法や装置は、いずれもガゼット袋を1個ずつ製造することは可能でも、2個のガゼット袋を同時に製造する、いわゆる2個取りと称する製造方法には適していないものであった。   Such conventional methods and apparatuses for producing gusset bags are suitable for a so-called two-piece production method in which two gusset bags are produced at the same time, even though it is possible to produce gusset bags one by one. It was not.

すなわち、従来の合成樹脂製袋を2個取りする製造方法では、1台の製造装置で2個の合成樹脂製袋を同時に製造するために、通常、袋の開口部を対向させた状態で製造している。そこで、従来の2個取りの製造方法でガゼット袋10を製造すると、帯状フィルムの幅員の両端部に角底部14が位置することになる(図17参照)。そのため、ガゼット袋10を2個取りするには、帯状フィルムの幅員の両端部に、夫々底フィルムを配設する2台の装置を設置する必要があるので、ガゼット袋の製造方法では、2個取りによる合理化は困難になっていた。   That is, in the conventional manufacturing method of taking two synthetic resin bags, in order to manufacture two synthetic resin bags at the same time with one manufacturing apparatus, it is normally manufactured with the opening portions of the bags facing each other. doing. Therefore, when the gusset bag 10 is manufactured by the conventional two-piece manufacturing method, the square bottom portions 14 are positioned at both ends of the width of the belt-like film (see FIG. 17). Therefore, in order to take two gusset bags 10, it is necessary to install two apparatuses for disposing the bottom films at both ends of the width of the belt-like film. The rationalization by taking was difficult.

一方、特許文献1及び特許文献2に記載のガゼット袋の製造方法では、ガゼット袋の横マチ部を形成する略筒状の横マチ成形材を設け、この横マチ成形材を上下2枚の帯状フィルムの間に長手方向に直交するように配する手段が採用されていた。ところが、帯状フィルムの搬送方向に対して横マチ成形材を横方向から搬送すると、搬送時の横マチ成形材が傾くなどの位置ずれが生じ易くなるものであった。そのため、従来のガゼット袋の製造方法で横マチ成形材を正確な位置に搬送するには、帯状フィルムの搬送速度を遅くする必要があった。   On the other hand, in the manufacturing method of the gusset bag described in Patent Document 1 and Patent Document 2, a substantially cylindrical lateral gusset forming material that forms the lateral gusset portion of the gusset bag is provided, and the lateral gusset forming material is formed into two upper and lower strips. A means for arranging the films so as to be orthogonal to the longitudinal direction has been adopted. However, when the horizontal gusset molding material is transported from the lateral direction with respect to the transport direction of the belt-like film, positional deviation such as tilting of the horizontal gusset molding material during transportation is likely to occur. Therefore, in order to transport the horizontal gusset molding material to an accurate position by the conventional method for producing a gusset bag, it is necessary to slow the transport speed of the belt-like film.

そこで、ガゼット袋を2個取りするために、通常の2倍の長さの横マチ成形材を横方向から搬送する場合、帯状フィルムの搬送速度を更に遅くする必要が生じる。その結果、製造時間が極めて遅くなり、ガゼット袋の2個取りによる合理化は一層困難になっていた。   Therefore, in order to take two gusset bags, when a horizontal gusset forming material having a length twice the normal length is transported from the lateral direction, it is necessary to further reduce the belt film transport speed. As a result, the manufacturing time has become extremely slow, and rationalization by taking two gusset bags has become more difficult.

更に、ガゼット袋には、開口部にフラップや把手、あるいはチャックを備えた各種のものが提供されている。ところが、従来の2個取りの製造方法では、袋の開口部を対向させた状態で製造するので、これらのフラップや把手等を対向した開口部に必要に応じて成形することは極めて困難であった。   Furthermore, various types of gusset bags having flaps, grips, or chucks at the openings are provided. However, in the conventional two-piece manufacturing method, since the bag is manufactured with the opening portions facing each other, it is extremely difficult to form these flaps, handles, etc. into the facing opening portions as necessary. It was.

このように、従来の2個取りの製造方法や従来のガゼット袋の製造方法によりガゼット袋を2個取りするには、解決すべき課題が極めて多い。そこで本発明は、上述の課題を解消すべく創出されたもので、ガゼット袋を効率良く2個取りすることが可能で、しかも、フラップや把手等を必要に応じて同時に成形することが可能な合成樹脂製ガゼット袋の製造方法及び製造装置の提供を目的とするものである。   Thus, in order to take two gusset bags by the conventional two-piece manufacturing method or the conventional gusset bag manufacturing method, there are extremely many problems to be solved. Therefore, the present invention has been created to solve the above-described problems, and can efficiently take two gusset bags, and can simultaneously mold a flap, a handle, and the like as necessary. It aims at providing the manufacturing method and manufacturing apparatus of a synthetic resin gusset bag.

Achieved the goal.

本発明合成樹脂製ガゼット袋の材質は、例えば、ポリプロピレンフィルムにナイロンフィルムがラミネートされたフィルム材や、LDPEフィルム、HDPEフィルム、PETフィルム、アルミ蒸着フィルムなど任意の合成樹脂材を使用することが可能である。   As the material of the synthetic resin gusset bag of the present invention, for example, any synthetic resin material such as a film material obtained by laminating a nylon film on a polypropylene film, an LDPE film, an HDPE film, a PET film, or an aluminum vapor deposition film can be used. It is.

本発明ガゼット袋10は合成樹脂材にて形成され、表胴部11、裏胴部12、横マチ部13、角底部14で構成される(図7、図10、図13、図16参照)。   The gusset bag 10 of the present invention is formed of a synthetic resin material, and includes a front barrel portion 11, a back barrel portion 12, a lateral gusset portion 13, and a square bottom portion 14 (see FIGS. 7, 10, 13, and 16). .

本発明製造方法は、特に、次の三つの手段を有するものである。すなわち、横マチ形成手段100、底部形成手段200、接合手段300である(図1参照)。   The production method of the present invention particularly has the following three means. That is, the horizontal gusset forming means 100, the bottom forming means 200, and the joining means 300 (see FIG. 1).

横マチ形成手段100は、横マチ成形材3を裏面フィルム2上に設置してから横マチ成形材3を二分するまでの手段となる。すなわち、ガゼット袋10の表胴部11を形成する帯状の表面フィルム1と裏胴部12を形成する帯状の裏面フィルム2とが重なるように予め設置されている(図2参照)。一方、横マチ成形材3は、合成樹脂製の帯状フィルムが扁平なチューブ状に折たたまれたもので、ガゼット袋10の横マチ部13を形成するフィルム部材である。   The horizontal gusset forming means 100 is a means from installing the horizontal gusset molding material 3 on the back film 2 to dividing the horizontal gusset molding material 3 into two. That is, the belt-like surface film 1 that forms the front body portion 11 of the gusset bag 10 and the belt-like back surface film 2 that forms the back body portion 12 overlap each other (see FIG. 2). On the other hand, the horizontal gusset molding material 3 is a film member in which a strip-like film made of a synthetic resin is folded into a flat tube shape and forms the horizontal gusset portion 13 of the gusset bag 10.

本発明では、ガゼット袋10を2個取りするために、製造するガゼット袋10の横マチ部13の略2倍の長さを有する横マチ成形材3を設ける(図6、図9、図12、図15参照)。同様に、表面フィルム1及び裏面フィルム2の幅員を、製造するガゼット袋10の高さの少なくとも2倍の幅員に形成している。そして、表面フィルム1と裏面フィルム2との間に2倍の長さを有する横マチ成形材3を横向きに配置する(図1参照)。   In the present invention, in order to take two gusset bags 10, the horizontal gusset forming material 3 having a length approximately twice as long as the horizontal gusset portion 13 of the gusset bag 10 to be manufactured is provided (FIGS. 6, 9, and 12). FIG. 15). Similarly, the width | variety of the surface film 1 and the back surface film 2 is formed in the width | variety of at least 2 times the height of the gusset bag 10 to manufacture. And the horizontal gusset molding material 3 which has double length between the surface film 1 and the back surface film 2 is arrange | positioned sideways (refer FIG. 1).

この横マチ形成手段100では、まず横マチ成形材3を裏面フィルム2の上方から裏面フィルム2上に載置する(図2参照)。次に、横マチ成形材3と裏面フィルム2とを仮止めする。そして、横マチ成形材3の上に表面フィルム1を配置した後、横マチ成形材3の長手中央部と表面フィルム1とが接着するように仮止めする。その後、横マチ成形材3の長さが二分されるように、横マチ成形材3の長手中央部から表面フィルム1ごと横マチ成形材3を切断する。図示例では、表面フィルム1及び横マチ成形材3を裏面フィルム2ごと二分している。また、裏面フィルム2を残して二分することも可能である。   In this horizontal gusset forming means 100, first, the horizontal gusset forming material 3 is placed on the back film 2 from above the back film 2 (see FIG. 2). Next, the horizontal gusset molding material 3 and the back film 2 are temporarily fixed. And after arrange | positioning the surface film 1 on the horizontal gusset molding material 3, it temporarily fixes so that the longitudinal center part of the horizontal gusset molding material 3 and the surface film 1 may adhere | attach. Then, the horizontal gusset molding material 3 is cut together with the surface film 1 from the longitudinal center of the horizontal gusset molding material 3 so that the length of the horizontal gusset molding material 3 is divided into two. In the illustrated example, the front film 1 and the horizontal gusset molding material 3 are divided into two halves together with the back film 2. It is also possible to bisect the back film 2.

底部形成手段200は、ガゼット袋10の角底部14を形成する帯状の底フィルム4を底部の位置に配する手段である(図1参照)。まず、横マチ成形材3の各切断口3Aを開いてガゼット袋10の底部に位置する横マチ成形材3の底面部3Bを夫々折り返す(図4参照)。このとき、横マチ成形材3の長手中央部から二分された前記表面フィルム1の切断端部1Aを幅員端部方向へ開くことで、横マチ成形材3の切断口3Aを開き、ガゼット袋10の底部に位置する横マチ成形材3の底面部3Bを表出する。次に、各底面部3Bに1枚の底フィルム4を接着する。最後に、折り返した底面部3Bを底フィルム4ごと閉じる工程となる。   The bottom portion forming means 200 is a means for arranging the belt-like bottom film 4 forming the square bottom portion 14 of the gusset bag 10 at the bottom position (see FIG. 1). First, each cutting opening 3A of the horizontal gusset molding material 3 is opened, and the bottom portion 3B of the horizontal gusset molding material 3 located at the bottom of the gusset bag 10 is folded back (see FIG. 4). At this time, by opening the cut end portion 1A of the surface film 1 divided in two from the longitudinal center portion of the horizontal gusset molding material 3 in the width end portion direction, the cut opening 3A of the horizontal gusset molding material 3 is opened, and the gusset bag 10 The bottom face part 3B of the horizontal gusset molding material 3 located at the bottom part of the sheet is exposed. Next, one bottom film 4 is bonded to each bottom surface portion 3B. Finally, it is a step of closing the folded bottom surface portion 3B together with the bottom film 4.

接合手段300は、表面フィルム1及び裏面フィルム2を接合した後、ガゼット袋10の輪郭に沿って切断し、2個のガゼット袋10を同時に成形する手段である(図1参照)。この手段では、まず、横マチ成形材3及び底フィルム4を、表面フィルム1と裏面フィルム2とに接合する。そして、表面フィルム1及び裏面フィルム2をガゼット袋10の輪郭に沿って切断する。このとき、2個のガゼット袋10は角底部14が対向した状態になっている(図6、図9、図12、図15参照)。この結果、ガゼット袋10の開口部は夫々外側に向いた状態で形成される。そのため、この接合手段300に多少変更を加えることで、ガゼット袋10の開口部15に、ヘッダー16、フラップ17、手提げ18、密封チャック19などを必要に応じて設けることが可能になる。   The joining means 300 is means for joining the front film 1 and the back film 2 and then cutting along the outline of the gusset bag 10 to simultaneously mold the two gusset bags 10 (see FIG. 1). In this means, first, the horizontal gusset molding material 3 and the bottom film 4 are joined to the front film 1 and the back film 2. Then, the front film 1 and the back film 2 are cut along the outline of the gusset bag 10. At this time, the two gusset bags 10 are in a state where the square bottom portions 14 are opposed to each other (see FIGS. 6, 9, 12, and 15). As a result, the openings of the gusset bag 10 are formed so as to face outward. Therefore, by slightly changing the joining means 300, the header 16, the flap 17, the handbag 18, the sealing chuck 19 and the like can be provided in the opening 15 of the gusset bag 10 as necessary.

図5乃至図7は、接合手段300において、一対のガゼット袋10の開口部15の位置にヘッダー16及びフラップ17を形成する工程を示している。すなわち、裏面フィルム2の幅員両端から延長された延長部材2Aを折り返して開口部15の位置にヘッダー16及びフラップ17を形成する工程である(図5参照)。このような工程により成形されたガゼット袋10には、ヘッダー16とフラップ17が形成されるものである(図7参照)。図示例では、フラップ17を折り込む際に、長尺状の粘着テープ17Aをフラップ17の内側に配している(図5参照)。そして、表面フィルム1と裏面フィルム2とを切断して2個のガゼット袋10を形成する際に、フラップ17付のガゼット袋10が形成される(図6参照)。   5 to 7 show a process of forming the header 16 and the flap 17 at the position of the opening 15 of the pair of gusset bags 10 in the joining means 300. That is, it is a step of forming the header 16 and the flap 17 at the position of the opening 15 by folding back the extending member 2A extended from both width ends of the back film 2 (see FIG. 5). A header 16 and a flap 17 are formed on the gusset bag 10 formed by such a process (see FIG. 7). In the illustrated example, when the flap 17 is folded, a long adhesive tape 17A is disposed inside the flap 17 (see FIG. 5). And when the front film 1 and the back film 2 are cut | disconnected and the two gusset bags 10 are formed, the gusset bag 10 with the flap 17 is formed (refer FIG. 6).

図8乃至図10は、接合手段300において、一対のガゼット袋10の開口部15の位置に手提げ18を形成する工程を示している。すなわち、表面フィルム1と裏面フィルム2との間に一対の接合フィルム6を配すると共に、一対の手提げ18を配置し、開口部15の位置に手提げ18を形成する工程である(図8参照)。図示例では、表面フィルム1と裏面フィルム2とが直接重合する面に一対の接合フィルム6を配し、該接合フィルム6と表面フィルム1および裏面フィルム2との間に手提げ18を介している。そして、この手提げ18を接合フィルム6と共に、表面フィルム1及び裏面フィルム2に溶着する(図9参照)。そして、前側面1と裏面フィルム2とを切断すると手提げ18付のガゼット袋10が形成される(図10参照)。   8 to 10 show a process of forming the handbag 18 at the position of the opening 15 of the pair of gusset bags 10 in the joining means 300. That is, it is a step of arranging a pair of bonding films 6 between the front film 1 and the back film 2, arranging a pair of handbags 18, and forming the handbags 18 at the positions of the openings 15 (see FIG. 8). . In the illustrated example, a pair of bonding films 6 is arranged on the surface where the surface film 1 and the back film 2 are directly polymerized, and a handbag 18 is interposed between the bonding film 6, the surface film 1 and the back film 2. And this handbag 18 is welded to the surface film 1 and the back film 2 with the joining film 6 (refer FIG. 9). And if the front side surface 1 and the back surface film 2 are cut | disconnected, the gusset bag 10 with the handbag 18 will be formed (refer FIG. 10).

図11乃至図13は、接合手段300において、一対のガゼット袋10の開口部15の位置に手提げ孔18Aを形成する工程を示している。図示例では、表面フィルム1と裏面フィルム2との間に一対の補強フィルム7を配置して一対のガゼット袋10の開口部の位置に接合する(図11参照)。更に、この補強フィルム7にて補強された部分の開口部15の位置に手提げ孔18Aを開穿する工程である。そして、前側面1と裏面フィルム2とを切断すると(図12参照)、手提げ孔18Aを備えたガゼット袋10が形成される(図13参照)。   FIGS. 11 to 13 show a process of forming the hand hole 18 </ b> A at the position of the opening 15 of the pair of gusset bags 10 in the joining means 300. In the example of illustration, a pair of reinforcement film 7 is arrange | positioned between the surface film 1 and the back surface film 2, and it joins to the position of the opening part of a pair of gusset bag 10 (refer FIG. 11). Further, it is a step of opening the hand-carrying hole 18A at the position of the opening 15 of the portion reinforced by the reinforcing film 7. And if the front side surface 1 and the back surface film 2 are cut | disconnected (refer FIG. 12), the gusset bag 10 provided with 18 A of handbag holes will be formed (refer FIG. 13).

図14乃至図16は、接合手段300において、一対のガゼット袋10の開口部15の位置に密封チャック19を形成する工程を示している。図示例では、まず、接着テープ9にて横マチ成形材3の開口側端部を表面フィルム1及び裏面フィルム2に接着する(図14参照)。次に、表面フィルム1と裏面フィルム2との間にチャック用帯体8を配置し、このチャック用帯体8を一対のガゼット袋10の開口部15の位置に接合する(図15参照)。この結果、各ガゼット袋10の開口部15に密封チャック19が設けられる(図16参照)。   14 to 16 show a process of forming the sealing chuck 19 at the position of the opening 15 of the pair of gusset bags 10 in the joining means 300.

As a result, the sealing chuck 19 is provided in the opening 15 of each gusset bag 10 (see FIG. 16).

次に、本発明の製造装置を説明する。本発明製造装置は、前記製造方法を実施する装置になっている。すなわち、合成樹脂製のガゼット袋10を2個取りする本発明装置の基本構成は、送り機構20、横マチ成形材配置機構30、裏面加熱シール機構40、表面加熱シール機構50、底部表出機構60、底部シール機構70、接合機構80を備えたものである(図2参照)。   Next, the manufacturing apparatus of the present invention will be described. The manufacturing apparatus of the present invention is an apparatus for performing the manufacturing method. That is, the basic configuration of the device of the present invention that takes two synthetic resin gusset bags 10 includes a feed mechanism 20, a horizontal gusset forming material arrangement mechanism 30, a back surface heating seal mechanism 40, a surface heating seal mechanism 50, and a bottom portion expression mechanism. 60, a bottom seal mechanism 70, and a joining mechanism 80 (see FIG. 2).

送り機構20は、表面フィルム1及び裏面フィルム2を長手方向に沿って移動する機構である(図2参照)。図示例では複数のローラー21を利用した送り機構20を示している。この送り機構20では、長手方向に沿って前記表面フィルム1や裏面フィルム2を水平移動する間に、斜め上方へ持ち上げ再び水平に戻す勾配部90を備えている。そして、後述する底部表出機構60と底部シール機構70との一部を、この勾配部90に配置したものである。   The feed mechanism 20 is a mechanism that moves the front film 1 and the back film 2 along the longitudinal direction (see FIG. 2). In the illustrated example, a feeding mechanism 20 using a plurality of rollers 21 is shown. The feeding mechanism 20 includes a slope portion 90 that is lifted obliquely upward and returned to the horizontal again while the front film 1 and the back film 2 are horizontally moved along the longitudinal direction. Then, a part of a bottom part expression mechanism 60 and a bottom part seal mechanism 70 described later are arranged in the gradient part 90.

横マチ成形材配置機構30は、横マチ成形材3を裏面フィルム2の上に設置する機構である(図3参照)。図示の横マチ成形材配置機構30には、裏面フィルム2の上方で、横マチ部13の2倍の長さの横マチ成形材3を切断するカッター31を備えている。このカッター31は、横マチ部13用のフィルム材を搬送する移動装置32で略筒状に折り畳んだ後に、所定長さに切断する。更に、切断した横マチ成形材3を把持具33にて把持した状態で駆動用ベルト34が移動すると、把持具33ごと横マチ成形材3が搬送レール35に沿って移動し、裏面フィルム2の上方から裏面フィルム2の上に横マチ成形材3を載置するものである(図2参照)。図示例の把持具33は、吸引エアーにて横マチ成形材3を吸着する構成を示しているが、把持具33の構成は、他のカム方式など任意に変更することができる。   The horizontal gusset molding material arrangement mechanism 30 is a mechanism for installing the horizontal gusset molding material 3 on the back film 2 (see FIG. 3). The illustrated horizontal gusset forming material arrangement mechanism 30 includes a cutter 31 for cutting the horizontal gusset forming material 3 having a length twice that of the horizontal gusset portion 13 above the back film 2. This cutter 31 is cut into a predetermined length after being folded into a substantially cylindrical shape by a moving device 32 that conveys the film material for the horizontal gusset portion 13. Further, when the driving belt 34 moves while the cut horizontal gusset molding material 3 is held by the gripping tool 33, the horizontal gusset molding material 3 moves along the transport rail 35 together with the gripping tool 33, and A horizontal gusset molding material 3 is placed on the back film 2 from above (see FIG. 2). The gripping tool 33 in the illustrated example shows a configuration in which the horizontal gusset molding material 3 is sucked by suction air, but the configuration of the gripping tool 33 can be arbitrarily changed, such as another cam system.

裏面加熱シール機構40は、裏面フィルム2上に横マチ成形材3を仮接着する機構である。図示例では、裏面フィルム2の下面側からシール用熱板41を当てて裏面フィルム2と横マチ成形材3とを仮接着している(図2参照)。   The back surface heat sealing mechanism 40 is a mechanism for temporarily adhering the horizontal gusset molding material 3 onto the back film 2. In the illustrated example, the back film 2 and the horizontal gusset molding material 3 are temporarily bonded by applying a sealing hot plate 41 from the lower surface side of the back film 2 (see FIG. 2).

表面加熱シール機構50は、横マチ成形材3上に表面フィルム1を仮接着する機構である。図示例では、裏面フィルム2上に仮接着された横マチ成形材3の上に表面フィルム1を配した後で、表面フィルム1の上面側からシール用熱板51を当てて横マチ成形材3の長手中央部と表面フィルム1とを仮接着している(図2参照)。   The surface heating sealing mechanism 50 is a mechanism for temporarily adhering the surface film 1 onto the horizontal gusset molding material 3. In the illustrated example, after the surface film 1 is arranged on the horizontal gusset molding material 3 temporarily bonded on the back film 2, the sealing gusset 51 is applied from the upper surface side of the surface film 1 to form the horizontal gusset molding material 3. Is temporarily bonded to the surface film 1 (see FIG. 2).

底部表出機構60は、横マチ成形材3の底面部3Bを夫々折り返す機構である(図2参照)。この底部表出機構60には、表面フィルム1と裏面フィルム2との長手方向に沿って横マチ成形材3を二分するカッター61を設けている。そして、二分された表面フィルム1の切断端部1Aに接触する拡開ローラー62を配置し、この拡開ローラー62にて表面フィルム1の切断端部1Aを開く(図4参照)。そうすると、この表面フィルム1に仮止めされた横マチ成形材3の切断口3Aも切断端部1Aと共に開口するものである。更にマチ成形材3の切断口3A側面に当接する折返し用板体63を配置する。この折返し用板体63は、横マチ成形材3の切断口3Aを横マチ成形材3の上に折り返してガゼット袋10の底部に位置する底面部3Bを形成する部材である。図示例の折返し用板体63は、拡開ローラー62にて広がった切断口3Aを上下から挟み込む一対の板状を成した構成である。   The bottom part expression mechanism 60 is a mechanism that folds back the bottom surface part 3B of the horizontal gusset forming material 3 (see FIG. 2). The bottom part exposing mechanism 60 is provided with a cutter 61 that bisects the horizontal gusset forming material 3 along the longitudinal direction of the front film 1 and the back film 2. And the expansion roller 62 which contacts the cutting edge part 1A of the divided | segmented surface film 1 is arrange | positioned, and the cutting edge part 1A of the surface film 1 is opened with this expansion roller 62 (refer FIG. 4). If it does so, the cutting opening 3A of the horizontal gusset molding material 3 temporarily fixed to this surface film 1 will also open with the cutting edge part 1A. Further, a folding plate 63 that contacts the side surface of the cutting opening 3A of the gusset forming material 3 is disposed. The folding plate 63 is a member that forms the bottom surface portion 3B located at the bottom of the gusset bag 10 by folding the cutting opening 3A of the lateral gusset molding material 3 onto the lateral gusset molding material 3. The folding plate 63 in the illustrated example has a configuration of a pair of plates that sandwich the cutting port 3 </ b> A widened by the spreading roller 62 from above and below.

更に、この底部表出機構60の折返し用板体63を配置した部分は、送り機構20の勾配部90に配置されている(図2参照)。このような傾斜した位置に底部表出機構60の一部を配置すると、シリンダー1の切断端部1Aや横マチ成形材3の切断口3Aの拡開が容易になり、拡開工程が確認し易くなる利点もある。   Further, the portion where the folding plate 63 of the bottom portion exposing mechanism 60 is disposed is disposed on the gradient portion 90 of the feeding mechanism 20 (see FIG. 2). If a part of the bottom part exposing mechanism 60 is arranged at such an inclined position, it becomes easy to expand the cut end 1A of the cylinder 1 and the cut opening 3A of the horizontal gusset molding material 3, and the expansion process is confirmed. There is also an advantage that it becomes easy.
