この発明は、フィルム状袋体の間口開口装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a frontage opening device for a film-like bag.
（従来の技術）
断熱カップや紙コツプ等の商品は、その使用に供される
までには、一般に薄手のビニル・ナイロン等の袋体の中
に重ねられて保管され、運搬されている。(Prior Art) Products such as insulating cups and paper cups are generally stored and transported in a bag made of thin vinyl, nylon, etc. before being put to use.
このように、薄手のビニル袋の中に商品を挿入する際に
は、ビニル袋は折畳んだ平面状のフィルムとなっていて
、その間口は相互に重なり合って、密着しているために
、流れ工程においては、この間口を機械的に開口すると
同時に、その間口から商品を挿入しなければならない。In this way, when inserting a product into a thin plastic bag, the plastic bag is a folded flat film, and the openings overlap and are in close contact with each other, so there is no flow. In the process, this opening must be opened mechanically and the product must be inserted through the opening at the same time.
そこで、従来は重なり合っている平面状のフィルム間口
付近の上部と下部を、相互に吸着して引っ張り合うこと
によって閉口間口を開口していた。Therefore, conventionally, the upper and lower parts of the overlapping planar films near the frontage were attracted to each other and pulled together to open the closed frontage.
その具体的な機械的構成は、下部の固定吸盤と上部の可
動吸盤とがフィルム間口を吸着し、可動吸盤の上方移動
によって開口するものである。The specific mechanical configuration is such that a lower fixed suction cup and an upper movable suction cup attract the film opening, and the opening is opened by upward movement of the movable suction cup.
（発明が解決しようとする課題）
上記の従来技術にあっては、フィルム間口を上部と下部
とから吸引するものであるが、このフイルム状袋体は、
その間口が密閉状に重なり合っているため、実際の開口
成功率は７０％程度に過ぎず、その流れ工程に支障を生
じていた。(Problems to be Solved by the Invention) In the above-mentioned conventional technology, the film opening is sucked from the upper and lower parts, but this film-like bag body
Since the openings overlap in a sealed manner, the actual opening success rate was only about 70%, which caused problems in the flow process.
（課題を解決するための手段）
本発明者は、如何にフィルム間口の開口成功率を高める
かについて鋭意研究の結果、従来どおりフィルム間口を
上部と下部とから吸着することに加え、同時に可動吸盤

その開口成功率を１００％にしたものである。(Means for Solving the Problems) As a result of intensive research on how to increase the success rate of opening the film opening, the inventors of the present invention discovered that, in addition to suctioning the film opening from the top and bottom as in the past, they also installed a movable suction cup. By giving the upper film wrinkles that converge on the sides,
The opening success rate is set to 100%.
次に、その具体的な解決手段を添付図面の符号に対応し
て説明する。Next, specific means for solving the problem will be explained in accordance with the reference numerals in the attached drawings.

盤９に吸着される。(Function) According to the present invention, when the film-like bag 15 is positioned on the base 11, the movable suction cup 9 comes into contact with the frontage of the film-like bag 15 due to the lowering of the upper mechanism 10. Lower mechanism 14
At the same time, the fixed suction cup 13 sucks the lower film at the opening of the film-like bag 15, and at the same time, in the lower mechanism 10,
The tension spring 6 is extended and the arm claws 4 and 5 move the shaft attachment part to the fulcrum 1.
6. Rotate a little inward to each other as 17 and press stopper 1.
．． Move away from 2. At this time, the arm claw 4.5 scrapes the upper film, giving the upper film wrinkles 18, which are concentrated on the movable suction cup 9 side, creating miscellaneous gaps in the previously sealed frontage, and causing the upper film to It is attracted by the movable suction cup 9.

。As the lower mechanism 10 rises, the movable suction cup 9 also rises, so that the film-like bag 15, which had been closed tightly due to the overlapping of the upper film and the lower film, is reliably opened and becomes flat. The plastic film becomes a three-dimensional bag-like object, and products can be easily and conveniently inserted through the opening. After that, the upper mechanism 10
At the same time, the suction action of the lower mechanism 14 is released, and the film bag 15 into which the product has been inserted is transferred from this device to the next process. Further, the arm pawl 4.5 is returned by the restoring force of the tension spring 6 and stopped at the original position by each stopper 1.2. By repeating this action, the product is automatically inserted into the film bag.

The arm claws 4 and 5 are pivoted using pins, and the lower parts of the arm claws 4 and 5 are in contact with the inside of the stopper 1.2, and a tension spring 6 is interposed between the upper parts. The operating body 7 was constructed by setting the following. Furthermore, this operating body 7
was fixed to a rectangular plate at ports 1 to 20 and 21 via a holding fitting 19 to a movable suction cup 9 equipped with a vacuum hose 8 to form an upper machine 4110. Reference numerals 22 and 23 in the figure indicate spring hooks.
