Description

本発明は、合成樹脂材にて形成される中仕切り付きガゼット袋の製造方法及び製造装置に係り、自動製袋機で中仕切りを有するガゼット袋を2個取りすることができる中仕切り付き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 method and an apparatus for manufacturing a gusset bag with a partition formed of a synthetic resin material, and an gusset bag with a partition that can take two gusset bags having a partition with an automatic bag making machine. The present invention relates to a manufacturing method and a manufacturing apparatus.

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.

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。   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 in a double fold shape and guiding it to the bottom part.

一方、ガゼット袋に中仕切りを設けた構成が特許文献3及び特許文献4に記載されている。特許文献3に記載のガゼット袋はレジ袋を構成し、横ガゼット袋からなるレジ袋に中仕切りを設けたものである。このレジ袋によると、収納部の四隅に、上下方向に柱状に延びる芯部を設けることにより収納部を形成し、この収納部に間仕切を配して区画を構成したものである。   On the other hand, the structure which provided the partition in the gusset bag is described in patent document 3 and patent document 4. The gusset bag described in Patent Document 3 constitutes a plastic bag, and a plastic bag comprising a horizontal gusset bag is provided with a partition. According to this shopping bag, a storage portion is formed by providing core portions extending in a columnar shape in the vertical direction at the four corners of the storage portion, and partitions are arranged in this storage portion to constitute a partition.

特許文献4は、多層紙、プラスチックラミネート紙等の適宜紙素材より成る底ガゼット袋の内部を区画する中仕切りシートを備えた仕切り付き袋が記載されている。この仕切り付き袋によると、中仕切りシートの下部及び両側部が袋本体に接着されているので、袋の強度が高まり、収納された物品が混じり合うのを防ぐことができるというものである。   Patent Document 4 describes a bag with a partition provided with a partition sheet that partitions the inside of a bottom gusset bag made of an appropriate paper material such as multilayer paper or plastic laminate paper. According to this bag with a partition, since the lower part and both side parts of the partition sheet are adhered to the bag body, the strength of the bag is increased, and the stored articles can be prevented from being mixed together.

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。   None of the conventional gusset bag manufacturing methods and apparatuses are suitable for a manufacturing method called so-called two-piece production, in which both gusset bags can be manufactured one by one, but two gusset bags are manufactured simultaneously. Met.

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を製造すると、帯状フィルムの幅員の両端部に角底部が位置することになる。そのため、ガゼット袋を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できない。   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 is manufactured by the conventional two-piece manufacturing method, the corner bottoms are located at both ends of the width of the belt-like film. Therefore, in order to take two gusset bags, it is necessary to install two apparatuses for disposing the bottom film at both ends of the width of the belt-like film. Cannot be rationalized.

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。   In the manufacturing method of the gusset bag described in Patent Literature 1 and Patent Literature 2, a substantially cylindrical lateral gusset forming material that forms the lateral gusset portion of the gusset bag is provided, and the lateral gusset molding material is formed of two upper and lower belt-like films. Means arranged so as to be orthogonal to the longitudinal direction between them was employed. 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不可能であった。   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 impossible to form these flaps, handles, etc. into the facing opening portions as necessary. It was.

一方、特許文献3や特許文献4に記載のような中仕切り部を設けたガゼット袋を2個取りする場合は、更に製造工程が複雑にならざるを得ない。すなわち、中仕切り部や、横マチ部を底部や表裏面に正確に接着する必要がある。したがって、中仕切り部を設けたガゼット袋を2個取りする製造は、実現が極めて困難であった。   On the other hand, when two gusset bags provided with a partition part as described in Patent Document 3 and Patent Document 4 are taken, the manufacturing process must be further complicated. That is, it is necessary to accurately bond the partition part and the horizontal gusset part to the bottom part and the front and back surfaces. Accordingly, it has been extremely difficult to produce two gusset bags provided with a partition.

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、中仕切り部付きのガゼット袋を2個取りすることが可能になり、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も可能な中仕切り部付き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。   Therefore, the present invention has been created to solve the above-mentioned problems, and it is possible to take two gusset bags with a partition portion, and simultaneously form a flap, a handle, and the like as necessary. An object of the present invention is to provide a manufacturing method and a manufacturing apparatus of a gusset bag with a partition portion that can be used.

本発明製造方法は、特に、次の四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、中仕切り形成手段200、底部形成手段300、接合手段400である(図1参照)。   The production method of the present invention particularly has the following four means. That is, the horizontal gusset forming means 100, the partition forming means 200, the bottom forming means 300, and the joining means 400 (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1参照)。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. In other words, 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. 1). 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1、図4、図5、図7、図9、図11、図13参照)。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, a 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. 1, 4, and 5). FIG. 7, FIG. 9, FIG. 11, FIG. 13). 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.

中仕切り形成手段200は、横マチ形成手段100と同様に、中仕切り成形材4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(図1参照)。この中仕切り成形材4は、合成樹脂製の帯状フィルムが長手方向に沿った二つ折り状に折たたまれたもので、ガゼット袋10の中仕切り部15を形成するフィルム部材である。   Similarly to the horizontal gusset forming means 100, the middle partition forming means 200 is a means from installing the middle partition molding material 4 on the back film 2 to dividing the horizontal gusset molding material 3 into two (see FIG. 1). The partition molding material 4 is a film member that is formed by folding a synthetic resin belt-like film in a double fold along the longitudinal direction, and forms the partition 15 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の中仕切り部15の略2倍の長さを有する中仕切り成形材4を設ける(図1、図4、図5、図7、図9、図11、図13参照)。そして、表面フィルム1と裏面フィルム2との間に2倍の長さを有する中仕切り成形材4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, a partition molding material 4 having a length approximately twice as long as the partition 15 of the gusset bag 10 to be manufactured is provided (FIGS. 1, 4, 5). FIG. 7, FIG. 9, FIG. 11, FIG. 13). And the partition forming material 4 which has double length between the surface film 1 and the back surface film 2 is arrange | positioned sideways (refer FIG. 1).

図1では1個の中仕切り成形材4を配置しているが、2個の中仕切り成形材4を配置することができる(図4参照)。このように、中仕切り成形材4の数や位置、あるいは中仕切り成形材4の長さなどは任意に設定することができる。   In FIG. 1, one partition molding material 4 is arranged, but two partition molding materials 4 can be arranged (see FIG. 4). Thus, the number and position of the partition molding material 4 or the length of the partition molding material 4 can be arbitrarily set.

この中仕切り形成手段200では、まず中仕切り成形材4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、中仕切り成形材4と裏面フィルム2とを仮止めする。そして、中仕切り成形材4の上に表面フィルム1を配置した後、中仕切り成形材4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、中仕切り成形材4の長さが二分されるように、中仕切り成形材4の長手中央部から表面フィルム1ごと中仕切り成形材4を切断する。   In this partition forming means 200, first, the partition forming material 4 is placed on the back film 2 from above the back film 2 (see FIG. 2). Next, the partition molding material 4 and the back film 2 are temporarily fixed. And after arrange | positioning the surface film 1 on the middle partition molding material 4, it fixes temporarily so that the longitudinal center part of the middle partition molding material 4 and the surface film 1 may adhere | attach. Then, the partition molding material 4 is cut together with the surface film 1 from the longitudinal center of the partition molding material 4 so that the length of the partition molding material 4 is divided into two.

底部形成手段300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5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。   The bottom part forming means 300 is a means for arranging the belt-like bottom film 5 forming the square bottom part 14 of the gusset bag 10 at the position of the bottom part (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.

続いて、中仕切り成形材4の各切断口4Aを開いてガゼット袋10の底部に位置する中仕切り成形材4の底面部4Bを夫々折り返す(図1参照)。このときも、中仕切り成形材4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、中仕切り成形材4の切断口4Aを開き、ガゼット袋10の底部に位置する中仕切り成形材4の底面部4Bを表出する。次に、各底面部3B、4Bに1枚の底フィルム5を接着する。最後に、折り返した底面部3B、4Bを底フィルム5ごと閉じる工程となる。   Subsequently, each cutting opening 4A of the partition forming material 4 is opened, and the bottom surface portion 4B of the partition forming material 4 located at the bottom of the gusset bag 10 is folded back (see FIG. 1). Also at this time, by opening the cut end portion 1A of the surface film 1 divided into two from the longitudinal central portion of the partition molding material 4 in the width end portion direction, the cut port 4A of the partition partition molding material 4 is opened, and the gusset bag The bottom surface portion 4B of the partition molding material 4 located at the bottom of 10 is exposed. Next, the bottom film 5 of 1 sheet is adhere | attached on each bottom face part 3B, 4B. Finally, it is a step of closing the folded bottom surfaces 3B and 4B together with the bottom film 5.

接合手段400は、表面フィルム1、裏面フィルム2、横マチ成形材3、中仕切り成形材4、底フィルム5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)。このとき、中仕切り成形材4は、二つに重なった長手側縁に沿って表面フィルム1と裏面フィルム2とに接合される。また、底フィルム5には、表面フィルム1、裏面フィルム2、横マチ成形材3、中仕切り成形材4の各底部が接合されるものである。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。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400に多少変更を加えることで、ガゼット袋10の開口部に、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 400 joins the front film 1, the back film 2, the horizontal gusset molding material 3, the partition molding material 4, and the bottom film 5, and then cuts the two gusset bags 10 by cutting along the outline of the gusset bag 10.

図15及び図16は、ガゼット袋10に形成する中仕切り部15の向きを変更した状態を示している。例えば、図15は、ガゼット袋10に2個の中仕切り部15を形成した際に、向かって右向きにすると、横マチ部13とで仕切られたスペースSが狭くなってしまう。そのため、図16のように、中仕切り部15を向かって左向きにすることで、中仕切り部15にて仕切られたスペースSが広くなる。このように、中仕切り部15の位置を変更することにより、開封し易くスペースSからの取出しが容易になるものである。   15 and 16 show a state in which the direction of the partition 15 formed in the gusset bag 10 is changed. For example, in FIG. 15, when the two partition portions 15 are formed in the gusset bag 10, the space S partitioned by the horizontal gusset portion 13 becomes narrower if it is directed rightward. Therefore, as shown in FIG. 16, the space S partitioned by the partition part 15 is widened by turning the partition part 15 leftward. In this way, by changing the position of the partition 15, it is easy to open and take out from the space S.
