本発明は、内容物をとり出す袋の口内に凹型と
凸型から成る咬合具（ジツパー）を取り付けた袋
を製袋し、同時に内容物をこの袋内に密封する方
法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention involves manufacturing a bag in which a zipper consisting of a concave and a convex shape is attached to the mouth of the bag from which the contents are taken out, and at the same time How to seal the inside of this bag.
［従来の技術］
口内に咬合具を取り付けた袋の移動製袋方法と
しては、フラツトなフイルムの両縁に沿つて凹型

ことにより、咬合具を袋の口内に取り付ける方法
が公知である（特開昭56−42640公報）。[Prior Art] A mobile bag making method for bags with an articulating device attached inside the mouth involves directly forming an articulating device consisting of concave and convex shapes along both edges of a flat film, and then moving this film along a mandrel. After occluding the articulating tool by bending it into a circle, heat sealing is performed along both edges, and then horizontally sealing is performed by applying a heat seal bar horizontally from both sides with the articulating tool side facing the front side. A method of attaching an articulating tool to the mouth of a bag is known (Japanese Patent Application Laid-Open No. 56-42640).
［従来技術の課題］
しかし、上記製袋方法においては次のような問
題がある。[Problems with the Prior Art] However, the above bag making method has the following problems.
ａ 袋本体となるフイルムの内側の両縁に近い処
に咬合具を形成しているため、フイルムは巾広
となり、これを円筒状に形成してから咬合具を
咬み合わせるため、この咬み合わせの技術が大
変難しく、実用的には相当遅いスピードでなけ
ればならない。このため、生産性が上らない。a Because the occlusion tool is formed near both edges of the inside of the film that forms the bag body, the film is wide, and since it is formed into a cylindrical shape and then the occlusion tool is engaged with it, this occlusion is The technology is very difficult, and for practical purposes the speed must be quite slow. For this reason, productivity does not increase.
ｂ 袋の口において、咬合具の外側をヒートシー
ルして袋の口を密封するため、袋の口の端部分
にヒートシール部分が位置し、袋の外観が悪
い。b. At the mouth of the bag, the outside of the articulator is heat-sealed to seal the mouth of the bag, so the heat-sealed portion is located at the end of the mouth of the bag, giving the bag a poor appearance.
ｃ 袋の口の端（外）にヒートシール部分が位置
すると、この分外力を受けてピンホールが発生
する辺が増加する。c If the heat-sealed portion is located at the edge (outside) of the mouth of the bag, the number of sides on which pinholes will occur due to external force increases accordingly.
本発明の目的は、生産性の向上と袋の外観が良
く、ピンホールが発生しにくい咬合具付袋の製袋

充填し、密封する方法。 A step of folding a zipper tape in which articulating tools consisting of concave and convex shapes are formed in parallel on one side of a plastic film in half and interlocking the concave and convex shapes during feeding, and a bag tape made of a flat plastic film. A step of winding it around a cylindrical mandrel and forming it into a cylindrical shape by pulling both longitudinal edges together so that the two edges of the zipper tape are folded in half and the bag tape formed into a cylindrical shape. With the edges facing each other with the articulating tool facing inside the bag tape, both edges of the zipper tape ahead of the articulating tool and both edges of the bag tape are overlapped with each other, and the outer sides of these overlapping edges are a step of heat-sealing both edges of the bag tape and both edges of the zipper tape by applying a heat seal bar to the cylindrical body formed by adhering the zipper tape and the bag tape to a position where the cylindrical body escaped from the lower end of the mandrel. The process of forming a bag by sandwiching it horizontally with a heat seal bar and sealing the bottom of the flattened cylindrical body with the zipper tape sandwiched therein; After putting the bag into the bag, the bag is sealed and sealed, and the middle of the mouth seal is cut horizontally with a cutting blade to cut off each bag. How to fill and seal the contents.

の連続により自動的に行なわれる。[Function] The zipper tape is unrolled from the roll in a flat state, and midway through, it is folded inward and engaged with the articulating tool. On the other hand, the bag tape is also unrolled from the roll, formed into a cylindrical shape by a mandrel, and pushed out with both edges drawn together in a state of folding hands. The zipper tape folded in half is placed so as to face both edges of the bag tape in the folded state, and both edges are inserted inside the folded palms. When the inside of the zipper tape and the bag tape are made of heat-sealable polyethylene, for example, a heat insulator such as Teflon tape is placed between both edges of the zipper tape, and in this state, both edges of the bag tape are A heat seal bar is fitted on the outside of the The sealing tape and the bag tape are heat-sealed by the heat of the heat silver, and the zipper tape is attached to the bag tape. Next, at a position away from the lower end of the mandrel, a heat seal bar is applied horizontally from both sides with the zipper tape on the front side to seal the bottom and form a bag. Note that the term "bottom seal" used here is for convenience of explanation, and refers to the side seal of the bag. After the bottom sealing is performed, the contents are put in from above the mandrel, and when the bag has moved one bag, the mouth sealing is performed again. The sealed bag drops and is taken out as one bag. Bag making, filling and sealing are automatically performed by the above sequence.
