【0043】 主歯車組立体9が減速歯車装置7の出力歯車8により、図1および図19中、 反時計回りに回転されるとき、最初、間欠歯車10の歯10aのない部分が伝達 歯車61と対向しているので、伝達歯車61は、回転されない。しかも、制御板 10cの鍔部10bが伝達歯車61の切欠き61aと係合しているので、伝達歯 車61は、所定回転角度位置に停止している。したがって、結束具絡め機構5は 、所定回転角度位置に停止している。主歯車組立体9がさらに回転し、切欠き6 1aと鍔部10cとの係合が外れ、間欠歯車10の歯10aが伝達歯車61と噛 合う。これにより、伝達歯車61は、所定回転角度位置から回転され、同時に、 結束具絡め機構5も所定回転角度位置から回転される。また、特に、図17から 理解できるように、所定回転角度位置に停止している伝達歯車62も、伝達歯車 61より少し遅れたタイミングで間欠歯車10の歯10aと噛合い、袋口切断機 構12を作動させる。間欠歯車10の歯10aの歯数と伝達歯車61および62 の歯数とは、同一に設定されている。したがって、主歯車組立体9が1回転する ことによって、伝達歯車61および62も、1回転され、常に、それぞれの所定 回転角度位置に戻って停止される。When the main gear assembly 9 is rotated counterclockwise in FIGS. 1 and 19 by the output gear 8 of the reduction gear unit 7, first, the portion of the intermittent gear 10 without the teeth 10 a is transmitted. Therefore, the transmission gear 61 is not rotated. Moreover, since the flange portion 10b of the control plate 10c is engaged with the notch 61a of the transmission gear 61, the transmission gear 61 is stopped at the predetermined rotation angle position. Therefore, the binding tool entanglement mechanism 5 is stopped at the predetermined rotation angle position. The main gear assembly 9 further rotates, the notch 61a is disengaged from the flange portion 10c, and the teeth 10a of the intermittent gear 10 mesh with the transmission gear 61. As a result, the transmission gear 61 is rotated from the predetermined rotation angle position, and at the same time, the binder entanglement mechanism 5 is also rotated from the predetermined rotation angle position. Further, in particular, as can be understood from FIG. 17, the transmission gear 62 stopped at the predetermined rotation angle position also meshes with the teeth 10a of the intermittent gear 10 at a timing slightly delayed from the transmission gear 61, so that the bag mouth cutting machine mechanism. 12 is activated. The number of teeth 10a of the intermittent gear 10 and the number of teeth of the transmission gears 61 and 62 are set to be the same. Therefore, when the main gear assembly 9 makes one rotation, the transmission gears 61 and 62 also make one rotation, and always return to their respective predetermined rotation angle positions and are stopped.
【0044】 このようにして、主歯車組立体9は、結束作業者が袋状物の口部を集束溝15 の下端の抜け防止部16まで押し下げることにより、トリガ2を押した後、スラ イダ組立体3、結束具ホルダ4、結束具絡め機構5、袋口切断機構12間の動作 のシーケンスとタイミングとを決定する。In this way, the main gear assembly 9 is operated by the binding operator by pushing down the mouth portion of the bag-like object to the pull-out preventing portion 16 at the lower end of the focusing groove 15 to push the trigger 2 and then the slider. The sequence and timing of operations among the assembly 3, the binder holder 4, the binder entanglement mechanism 5, and the bag mouth cutting mechanism 12 are determined.
