Description

明細書 包装装置 技術分野  Description Packaging equipment Technical field
本発明は、 フィルムを筒状に製袋しつつ被包装物をフィルム内に次々と連続的 に包装する包装装置に関するものである。 背景技術  TECHNICAL FIELD The present invention relates to a packaging apparatus for successively wrapping articles to be packaged in a film while making the film into a tubular shape. Background art
この種の包装装置として一般的な横ピロ一包装装置としては、 搬送装置により 搬送するフィルムを筒状に製袋しながら被包装物を所定間隔毎に供給した後、 フ ィルムの二つ折り重合部を横シール装置により筒状にヒートシールし、 次いで各 被包装物間を縦ヒートシールした後に切断装置によって前記フィルムの縦ヒート シール箇所を切断して包装袋を搬送するように構成している。  As a general type of horizontal packaging device for this type of packaging device, a transport device feeds the packaged material at predetermined intervals while forming the film to be transported into a cylindrical shape, and then forms a two-fold overlapping portion of the film. Is heat-sealed in a tubular shape by a horizontal sealing device, and then, after vertically heat-sealing the objects to be packaged, the cutting device cuts the heat-sealed portion of the film and transports the packaging bag.
この際、 前記被包装物の大きさが比較的小さい場合やフィルムの厚みが厚く剛 性が高い場合などは、 前記切断装置により分離された包装袋を搬送装置によって 安定した状態で搬出することができるが、 嵩張り易い被包装物においては、 フィ ルムによつて包装した時に膨らんでしまい、 外観状その包装形態が悪くなつてし まうという問題がある。  At this time, when the size of the packaged object is relatively small, or when the film is thick and the rigidity is high, the packaging bag separated by the cutting device may be unloaded in a stable state by a transport device. It is possible, but there is a problem that the bulky packaged material swells when packaged with a film, and the appearance and packaging form are deteriorated.
このため、 包装形態を良好にしつつ内容物である被包装物を奇麗に包装する手 段として、 嵩張り易い被包装物を包み込む形態として、 フィルムの両端部の側方 を内側に折り込んでガゼット整形した後に包装袋をヒートシールする構造を採用 することがある。  For this reason, as a means to cleanly pack the contents to be packaged while improving the packaging form, and to wrap the bulky objects to be packaged, the sides of both ends of the film are folded inward to form a gusset. In some cases, the packaging bag is heat-sealed after completion.
この場合、たとえば特公平 3— 6 6 2 0 7号公報などで提案されているように、 ガゼッ卜整形の際にフィルムに皺や位置ずれなどが生じないようにフィルムを吸 着保持した状態でガゼッ卜整形する手段が講じられているが、 このフィルムの押 さえ機構である吸着装置が大型化し、 且つ機構が複雑となり易くなるため、 前述 した縦シール装置や切断装置などの配置位置などスペース的においても難点があ り、 全体の包装装置が大型化したりコストも高くなつてしまうという問題が残さ れている。 In this case, as proposed in, for example, Japanese Patent Publication No. 3-66207, the film is sucked and held so that the film does not wrinkle or shift during gusset shaping. Although gusset-shaping means is provided, the suction device, which is a mechanism for holding the film, becomes large-sized and the mechanism tends to be complicated. However, there is still a problem that the whole packaging equipment becomes large and the cost becomes high. Have been.
また、 一方従来の包装装置においては、 切り離した被包装物入り包装袋を更に 送り出す乗り移り搬送装置を前記搬送装置の搬送側に連設状態に設けられており、 一般的に前記縦シール装置や切断装置などは搬送方向を分断するように開閉 （移 動） する装置であるために、 この乗り移り装置は前記搬送装置をそのまま単に延 長したものとすることができず、 従って、 この搬送ルートを分断するように前記 縦シール装置や切断装置を設けなくてはならない。  On the other hand, in the conventional packaging device, a transfer carrier device for further feeding the detached packaging bag containing the article to be packaged is provided in a continuous state on the transport side of the transport device, and generally the vertical sealing device and the cutting device are provided. Is a device that opens and closes (moves) so as to divide the transport direction, so this transfer device cannot simply extend the transport device as it is, and therefore, divides this transport route. Thus, the vertical sealing device and the cutting device must be provided.
即ち、 簡単な例で説明すれば、 搬送装置の搬送終端に上下方向に開閉作動する 前記切断装置などを配設し、 この切断装置を介して搬送装置の終端とは所定の間 隔を隔てて乗り移り搬送装置を設けなければならないため、 この離間する搬送装 置と乗り移り搬送装置との間で包装袋の乗り移りがスムーズに行えなかったり、 乗り移り搬送が確実となるように前記搬送装置と乗り移り搬送装置とを上下に段 差を設けて重合するように配設し、 切断されて分離した包装袋が落下して乗り移 るようにしたり、 乗り移りが良好となるように別に乗り移り補助機構を付加した りしなければならないという問題もあった。  That is, to explain in a simple example, the cutting device or the like that opens and closes in the vertical direction is disposed at the transfer end of the transfer device, and is separated from the end of the transfer device by a predetermined distance via the cut device. Since the transfer device must be provided, the transfer device and the transfer device may not be able to smoothly transfer the packaging bag between the transfer device and the transfer device. The upper and lower parts are arranged so that they are superimposed, so that the cut and separated packaging bags fall and transfer, and a separate transfer assist mechanism is added to improve the transfer. There was also the problem of having to do it.
特に被包装物が重いものであったり、 底部が引っ掛かり易いものである場合に は、 この乗り移りがスムーズに行えず搬送排出に支障を来す虞があつた。  In particular, when the packaged material is heavy or the bottom is easily caught, the transfer cannot be performed smoothly, and there is a risk that the conveyance and discharge may be hindered.
本発明は、 従来の包装装置にこのような問題があることを見い出し、 嵩張りや すい被包装物を簡単な構成で安定状態に保持しつつガゼット整形ができるととも に、 その包装形態を良好にし、 しかも被包装物入り包装袋を簡便に搬送すること のできる包装装置を提供することを目的としている。 発明の開示  The present invention has found that the conventional packaging apparatus has such a problem, and it is possible to form a gusset while maintaining a bulky object to be packaged in a stable state with a simple configuration and improve the packaging form. It is another object of the present invention to provide a packaging device capable of easily transporting a packaging bag containing an article to be packaged. Disclosure of the invention
