この考案は、例えば、段ボール製や合成樹脂等の適宜材質で形成された上面開 放形態の箱体内部に、合成樹脂製又は紙製の袋体を敷設する作業に用いられる袋 敷設装置に関する。 The present invention relates to a bag laying device used for laying a bag made of synthetic resin or paper inside a box having an open upper surface made of an appropriate material such as cardboard or synthetic resin.
【０００２】[0002]
従来、上述例のような段ボール箱に包装袋を敷設する装置としては、例えば、 当出願人が既に開発済みの袋敷設装置（特願平５−６３３５４号）がある。 Conventionally, as an apparatus for laying a packaging bag in a cardboard box like the above example, there is, for example, a bag laying apparatus (Japanese Patent Application No. 5-63354) already developed by the applicant.
【０００３】 この袋敷設装置は、箱送りコンベア上の挿入位置に段ボール箱を搬送した後、 同位置上部に配設した袋保持機構を駆動して、４枚の各折返し爪で保持した包装 袋内に噴射ノズルから吐出する加圧エアを供給し、同各折返し爪で保持した包装 袋を拡張して段ボール箱に被覆セットする。この後、同位置に配設した袋装填機 構を駆動して、段ボール箱に被覆した包装袋内に押込み板を垂直挿入し、同段ボ ール箱内部と対応する大きさに包装袋を押広げて敷設セットする装置である。This bag laying device conveys a cardboard box to an insertion position on a box feed conveyor, and then drives a bag holding mechanism arranged at the upper part of the same position to drive a packing bag held by four folding claws. Pressurized air discharged from the spray nozzle is supplied into the inside, and the packaging bag held by each folding claw is expanded and set on the cardboard box.

It is a device that spreads and lays and sets.
【０００４】[0004]
しかし、上述の袋敷設装置は、箱送りコンベア上の挿入位置に各機構を集合配 置しているので、装置全体の構造が複雑となり、一部の機構に故障が起きた場合 、隣設した各機構の一部又は全部を取り外さなければ、その故障部分を点検修理 することができず、部品交換や保守点検、位置調節等の作業が困難である。且つ 、段ボール箱に被覆された包装袋の押広げ作業が終了するまで、次の段ボール箱 に包装袋を敷設するための作業が行えず、一つの包装袋を敷設するときに要する 作業時間が長くなるので、単位時間当たりの処理枚数が少ないという問題点を有 している。 However, in the bag laying device described above, since each mechanism is collectively arranged at the insertion position on the box feed conveyor, the structure of the entire device becomes complicated, and if some of the mechanisms fail, they are installed next to each other. If some or all of each mechanism is not removed, the failed part cannot be inspected and repaired, and it is difficult to replace parts, perform maintenance and inspection, and adjust the position. Moreover, the work for laying the packaging bag on the next cardboard box cannot be performed until the work of spreading the packaging bag covered with the cardboard box is completed, and the work time required for laying one packaging bag is long. Therefore, there is a problem that the number of processed sheets per unit time is small.
【０００５】 この考案は上記問題に鑑み、適宜大きさに形成した袋体内に加圧エアを供給し て拡張する袋拡張手段と、該袋体内に押広げ体を挿入して押広げる袋押広げ手段 とを独立して設けることにより、部品交換、保守点検、位置調節等の作業が容易 に行え、処理枚数の増加させて能力アップを図ることのできる袋敷設装置の提供 を目的とする。In view of the above problems, the present invention has a bag expanding means for supplying pressurized air into a bag body having an appropriate size to expand the bag body, and a bag expanding method for inserting and expanding the bag by expanding the bag. It is an object of the present invention to provide a bag laying device capable of easily performing work such as parts replacement, maintenance and inspection, position adjustment, and the like, and increasing the number of processed sheets to improve the capacity by providing the means independently.

この考案は、上記箱送りコンベア上に設定した挿入位置に、上記袋保持手段で 保持した袋体内に噴射ノズルから吐出する加圧エアを供給して適宜大きさに拡張 する袋拡張手段を設け、上記挿入位置後段に設定した押込み位置に、上記箱体に 装填された袋体内に押広げ体を垂直挿入して適宜大きさに押広げる袋押広げ手段 を設けた袋敷設装置であることを特徴とする。 This invention provides bag expanding means for supplying compressed air discharged from an injection nozzle into a bag held by the bag holding means and expanding the bag to an appropriate size at an insertion position set on the box feed conveyor. The bag laying device is provided with a bag pushing and unfolding means for vertically inserting the pushing and unfolding body into the bag body loaded in the box body and pushing it to an appropriate size at the pushing position set in the latter stage of the inserting position. And

この考案は、箱送りコンベア上の挿入位置に配設した袋拡張手段を駆動して、 袋保持手段で保持した袋体内に噴射ノズルから吐出する加圧エアを供給し、同手 段で保持した袋体を拡張して箱体内部に装填する。この後、箱送りコンベア上の 押込み位置に配設した袋押広げ手段を駆動して、箱体に装填された袋体内に押広 げ体を垂直挿入し、同箱体内部と対応する大きさに袋体を押広げて敷設セットす るので、各作業が独立して行える。 In this invention, the bag expanding means arranged at the insertion position on the box feed conveyor is driven to supply the pressurized air discharged from the injection nozzle into the bag body held by the bag holding means, and the bag is held at the same stage. Expand the bag and load it inside the box. After that, the bag push-out means arranged at the push-in position on the box feed conveyor is driven to vertically insert the pusher into the bag loaded in the box, and the size corresponding to the inside of the box Since the bag is pushed out and set for laying, each work can be done independently.
【０００８】[0008]
この考案によれば、適宜大きさに袋体を加圧エアにより拡張する袋拡張手段と 、同袋体を押広げ体により押広げる袋押広げ手段とを独立して設けているので、 各部分の構造が簡素化され、一部に故障が起きても、その故障部分のみを点検修 理するだけで済み、部品交換、保守点検、位置調節等の作業が容易に行える。 According to this invention, the bag expanding means for expanding the bag body to an appropriate size by the pressurized air and the bag expanding means for expanding the bag body by the expanding and expanding body are independently provided. The structure is simplified, and even if a part fails, it is only necessary to inspect and repair the failed part, and parts replacement, maintenance and inspection, position adjustment, etc. can be performed easily.
【０００９】 且つ、従来装置のように袋体の押広げ作業が終了するまで、次の箱体に袋体を 敷設する作業を停止させる必要がなく、各作業を独立して行うので、一つの袋体 を敷設するときに要する作業時間が大幅に短縮でき、単位時間当たりの処理枚数 の増加させて能力アップを図ることができる。Further, unlike the conventional apparatus, it is not necessary to stop the work of laying the bag body on the next box until the work of spreading the bag body is completed, and each work is performed independently. The work time required for laying bags can be greatly reduced, and the number of sheets processed per unit time can be increased to improve the capacity.
