Description

前記不良信号が出力された際の供給コンベヤ16における第1の送り制御について、図2および図3を参照して説明する。なお、本例では、フィルムFの継ぎ目が含まれる包装サイクルとその次の包装サイクルとの2包装サイクル分についてを包装不良品Bとして取り扱う場合について例示する。前記検知センサ34で検知された継ぎ目についてのフィルム搬送方向の送り位置を特定する不良信号が出力されてから、所定の包装サイクル数経過後に前記継ぎ目に応じて包装不良品BとすべきフィルムFが製袋手段14に至る。そして、前記包装不良品BとすべきフィルムFが製袋手段14に至る包装サイクルに合わせて、フィルムFに供給コンベヤ16からの物品Gの送り込みを休止すべく、供給コンベヤ16を減速走行して停止した後に加速して走行を再開するよう、供給コンベヤ16の駆動モータ18を変速制御する。それにより、包装速度が高速に設定されている場合に、供給コンベヤ16の走行速度が速いので、供給コンベヤ16の走行を一時停止したのに関わらず該物品Gが慣性によって先走りしてしまい、図3(b)に示すように、製袋手段14で成形されたフィルムFへの物品Gの送り込み位置が下流側へ位置ずれして、継ぎ目を含む包装サイクルとその次の包装サイクルとのフィルムFに跨った状態で物品Gが供給される。そして、1包装サイクル分の供給コンベヤ16の走行休止制御が行われて、図3(c)に示すように、筒状に成形されたフィルムFが前記横シール位置まで搬送された際の包装サイクルにおいて、前述の如くフィルムF中に位置ずれ状態で供給された物品Gが、前記ール体28で噛み込まないようにするために、継ぎ目が横シール位置へ搬送されたときの包装サイクルとその次の包装サイクルとの間における横シール動作を休止するよう、横シール手段26の駆動モータ30が前記制御部36により制御される。すなわち、検知センサ34から前記不良信号が出力されてから、搬送されるフィルムFは所定包装サイクル経過後において下流側の横シール手段26に至り、継ぎ目が位置する2包装長分のフィルムFの前後位置を横シール・切断することで、1包装分の物品Gが収容されて前記継ぎ目が存在する2包装長分のフィルム長さからなる袋として包装不良品Bを得ることができる。 The 1st feed control in the supply conveyor 16 when the said defect signal is output is demonstrated with reference to FIG. 2 and FIG. In this example, a case where two packaging cycles including a packaging cycle including the seam of the film F and the next packaging cycle are handled as defective packaging products B is illustrated. The film F to be a defective packaging product B according to the seam after the lapse of a predetermined number of packaging cycles after the failure signal specifying the feeding position in the film transport direction for the joint detected by the detection sensor 34 is output. The bag making means 14 is reached. Then, the supply conveyor 16 is decelerated to stop the feeding of the article G from the supply conveyor 16 to the film F in accordance with the packaging cycle in which the film F to be the defective packaging B reaches the bag making means 14. The drive motor 18 of the supply conveyor 16 is controlled to change speed so as to accelerate after the stop and resume running. As a result, when the packaging speed is set to a high speed, the traveling speed of the supply conveyor 16 is fast, so that the article G is advanced by inertia regardless of whether the traveling of the supply conveyor 16 is temporarily stopped. As shown in FIG. 3 (b), the feeding position of the article G to the film F formed by the bag making means 14 is shifted to the downstream side, and the film F in the packaging cycle including the seam and the next packaging cycle. The article G is supplied in a state of straddling. Then, the travel stop control of the supply conveyor 16 for one packaging cycle is performed, and as shown in FIG. 3C, the packaging cycle when the film F formed into a cylindrical shape is conveyed to the lateral seal position. in the supplied goods G in position shift state in as described above the film F is, in order to prevent pinched by the sheet Lumpur 28, and the wrapping cycle when the seam is conveyed to the lateral sealing position The drive motor 30 of the lateral sealing means 26 is controlled by the control unit 36 so as to pause the lateral sealing operation during the next packaging cycle. That is, after the failure signal is output from the detection sensor 34, the film F to be conveyed reaches the downstream side sealing means 26 after a predetermined packaging cycle, and before and after the film F for two packaging lengths where the seam is located. By horizontally sealing and cutting the position, a defective packaging product B can be obtained as a bag having a film length of two packaging lengths in which an article G for one packaging is accommodated and the seam is present.

〔実施例の作用〕
次に、実施例の作用について説明する。製袋手段14に向けて搬送されるフィルムFの不良箇所に関してその位置を特定する不良信号出力に基づき、前記不良箇所に応じて包装不良品BとすべきフィルムFがフィルム成形位置に至る包装サイクル数経過後に、供給コンベヤ16からの物品供給を休止すべく供給コンベヤ16を減速・増速走行するように制御することで、包装不良品BとすべきフィルムFに供給コンベヤ16から送り込む物品Gを制限し、包装不良品Bとして取り扱う物品Gの絶対数を減らすことができる。このようなフィルムFの不良で包装不良品Bとなった包装を解袋して袋と物品Gとを分別して回収するときの物品Gの回収数を減することができる。そして、食品包装においては、包装不良品Bとして区分された包装済の内容物も含めて不良品として処分しなくてはならないこともある。前述した供給コンベヤ16の送り制御によれば、いずれも物品GのフィルムFへの送り込みを制限することができるので、そのような物品Gの無駄を削減することができる。また、供給コンベヤ16の送り制御によってフィルムFにずれた状態で物品Gが供給されても、横シール手段26による横シール動作を休止するので、横シール手段26で位置ずれしている物品Gを噛み込んで損傷するようなことがないので、解袋して回収する物品Gは、包装前と同じ良品として回収することができる。包装不良品Bとして、1包装長より長いフィルムF中に少なくとも1個の物品Gが収容された良品と異なる形態となるので、良品と不良品との判別が容易で、目視など、人手により包装不良品Bを分別する場合における選別漏れを防止できる。そして、包装不良率を低減できると共に、包装稼動率を向上できるなど、包装作業に係る効率化をなし得る。
(Effects of Example)
Next, the operation of the embodiment will be described. A packaging cycle in which the film F to be a defective packaging product B reaches the film forming position in accordance with the defective portion based on a defect signal output that specifies the position of the defective portion of the film F conveyed toward the bag making means 14. After a few minutes, the article G to be fed from the supply conveyor 16 to the film F to be a defective packaging B is controlled by controlling the supply conveyor 16 to decelerate and increase speed so as to stop the supply of articles from the supply conveyor 16. It is possible to reduce the absolute number of articles G that are limited and handled as defective packaging products B. It is possible to decline the collection number of articles G when such film was Kaibukuro defective packaging defective B and became packaging F recovered by separating the bag and the article G. In food packaging, it may be necessary to dispose of the packaged contents classified as defective packaging B as defective products. According to the feed control of the supply conveyor 16 described above, since it is possible to limit the feeding of the article G to the film F, such waste of the article G can be reduced. Further, even if the article G is supplied in a state of being shifted to the film F by the feed control of the supply conveyor 16, the lateral sealing operation by the lateral sealing means 26 is suspended, so that the article G that has been displaced by the lateral sealing means 26 is removed. Since there is no possibility of being damaged by biting, the article G that is unpacked and collected can be collected as the same good product as before packaging. Since the defective packaging B is different from a non-defective product in which at least one article G is accommodated in a film F longer than one packaging length, it is easy to discriminate between a good product and a defective product. It is possible to prevent omission of sorting when the defective product B is separated. And while being able to reduce a packaging defect rate and improving a packaging operation rate, the efficiency which concerns on packaging work can be achieved.
