　第１リンク９１の他端には、第２リンク９２が回転可能に連結されている。第２リンク９２は、架台５１の第１サイドフレーム６１又は第２サイドフレーム６２と連結されている。回転軸５９ａが回転すると、架台５１は鉛直方向Ｖに移動する。架台５１が鉛直方向Ｖに移動することにより、第１シールジョー５６、第２シールジョー５７及び受け部材４０も、鉛直方向Ｖに移動する。詳細は後述するが、鉛直移動機構５５が鉛直方向Ｖにおいて架台５１の往復駆動を繰り返すことにより、振動動作が実現される。 A second link 92 is rotatably connected to the other end of the first link 91 . The second link 92 is connected to the first side frame 61 or the second side frame 62 of the pedestal 51 . The pedestal 51 moves in the vertical direction V when the rotating shaft 59a rotates. As the mount 51 moves in the vertical direction V, the first sealing jaw 56, the second sealing jaw 57 and the receiving member 40 also move in the vertical direction V. As shown in FIG. Although the details will be described later, the vertical movement mechanism 55 repeats the reciprocating drive of the pedestal 51 in the vertical direction V, thereby realizing the vibration operation.
　（４）サイクル動作
　図６は、制御部１７が実行するサイクル動作を説明するための側面図である。図６では、便宜上、第１シールジョー５６及び第２シールジョー５７並びに第１接触部１８ｃ及び第２接触部１９ｃのみを示している。図７は、サイクル動作における第１シールジョー５６及び第２シールジョー５７の鉛直方向Ｖにおける移動速度の変化を示すタイムチャートである。なお、図６は、サイクル動作の前後における第１シールジョー５６及び第２シールジョー５７並びに第１接触部１８ｃ及び第２接触部１９ｃの動作の順序を示している。このため、サイクル動作における各部の動作の時間的な長さは、図６の縮尺通りでない場合もある。また、図７では、便宜上、第１シールジョー５６及び第２シールジョー５７の移動速度を示したが、第１シールジョー５６及び第２シールジョー５７に一体的に配置された受け部材４０も同じ速度で移動する。 (4) Cycle Operation FIG. 6 is a side view for explaining the cycle operation executed by the control section 17. FIG. 6 shows only the first sealing jaw 56, the second sealing jaw 57, and the first contact portion 18c and the second contact portion 19c for the sake of convenience. FIG. 7 is a time chart showing changes in moving speed in the vertical direction V of the first sealing jaw 56 and the second sealing jaw 57 during cycle operation. 6 shows the order of operations of the first sealing jaw 56, the second sealing jaw 57, the first contact portion 18c and the second contact portion 19c before and after the cycle operation. For this reason, the time length of the operation of each part in the cycle operation may not be exactly as shown in FIG. 7 shows the moving speed of the first sealing jaw 56 and the second sealing jaw 57 for the sake of convenience, the same applies to the receiving member 40 integrally arranged with the first sealing jaw 56 and the second sealing jaw 57. move at speed.
　サイクル動作は、第１動作と、第２動作とを含む。また、第１動作は、第１フェーズ及び第２フェーズからなる。図６に示されるように、第１フェーズの開始前において、第１シールジョー５６及び第２シールジョー５７の下方のフィルム筒ＦＴの内部には、１つの袋Ｗに包装されるべき量の物品Ａが既に投入されている。 A cycle operation includes a first operation and a second operation. Also, the first operation consists of a first phase and a second phase. As shown in FIG. 6, before the start of the first phase, the amount of articles to be packaged in one bag W is placed inside the film tube FT below the first sealing jaws 56 and the second sealing jaws 57 . A has already been entered.
　サイクル動作の間、プルダウンベルト１３は、横シール機構１５にフィルムＦを連続的に搬送している。このため、制御部１７は、第１フェーズ及び第２フェーズにおいて、鉛直移動機構５５に、横シール機構１５の鉛直方向Ｖの位置をフィルム筒ＦＴの鉛直方向Ｖにおける移動に合わせて適宜変化させる。 The pull-down belt 13 continuously conveys the film F to the horizontal sealing mechanism 15 during the cycle operation. Therefore, in the first phase and the second phase, the control unit 17 causes the vertical movement mechanism 55 to appropriately change the position of the horizontal sealing mechanism 15 in the vertical direction V in accordance with the movement of the film tube FT in the vertical direction V.
　（４－１）第１動作
　第１動作は、制御部１７が、水平移動機構５４に、第１シールジョー５６及び第２シールジョー５７を互いに接近するように水平方向Ｈに移動させることにより開始される。また、第１動作は、制御部１７が、挟み込んだフィルム筒ＦＴに熱を加えて横シールをした第１シールジョー５６及び第２シールジョー５７を互いに離間させることにより完了する。 (4-1) First operation The first operation is started by the control unit 17 causing the horizontal movement mechanism 54 to move the first sealing jaw 56 and the second sealing jaw 57 toward each other in the horizontal direction H. be done. The first operation is completed when the control unit 17 separates the first sealing jaw 56 and the second sealing jaw 57 that have laterally sealed the sandwiched film tube FT by applying heat.
　（４－１－１）第１フェーズ
　第１フェーズの開始時、第１シールジョー５６及び第２シールジョー５７は、フィルム筒ＦＴに接触しない位置で互いに離間している。また、第１接触部１８ｃ及び第２接触部１９ｃも、フィルム筒ＦＴに接触しない位置で互いに離間している。 (4-1-1) First Phase At the start of the first phase, the first sealing jaw 56 and the second sealing jaw 57 are separated from each other so as not to contact the film tube FT. Further, the first contact portion 18c and the second contact portion 19c are also separated from each other at a position where they do not contact the film tube FT.
　第１フェーズでは、制御部１７は、水平移動機構５４に、第１シールジョー５６及び第２シールジョー５７を互いに接近するように水平方向Ｈに移動させる。これにより、第１シールジョー５６及び第２シールジョー５７に一体的に配置された受け部材４０の第１接触部１８ｃ及び第２接触部１９ｃも互いに接近するように水平方向Ｈに移動する。第１接触部１８ｃ及び第２接触部１９ｃがフィルム筒ＦＴと接触した時、第１フェーズが終了し第２フェーズが開始される。 In the first phase, the control unit 17 causes the horizontal movement mechanism 54 to move the first sealing jaw 56 and the second sealing jaw 57 in the horizontal direction H so as to approach each other. As a result, the first contact portion 18c and the second contact portion 19c of the receiving member 40 integrally arranged with the first sealing jaw 56 and the second sealing jaw 57 also move in the horizontal direction H so as to approach each other. When the first contact portion 18c and the second contact portion 19c contact the film tube FT, the first phase ends and the second phase starts.
　（４－１－２）第２フェーズ
　第２フェーズでは、制御部１７は、第１動作が完了する前（言い換えると、第２フェーズが完了する前）に、鉛直移動機構５５に横シール機構１５を振動させる振動動作を実行するとともに、第１シールジョー５６及び第２シールジョー５７にフィルム筒ＦＴを横シールさせる。また、第２フェーズが開始されると、制御部１７は、物品排出装置２０に１つの袋Ｗに包装されるべき量の物品Ａを排出させる。 (4-1-2) Second Phase In the second phase, the control unit 17 causes the vertical movement mechanism 55 to move the horizontal sealing mechanism 15 before the first operation is completed (in other words, before the second phase is completed). , and causes the first sealing jaw 56 and the second sealing jaw 57 to laterally seal the film tube FT. Further, when the second phase is started, the control section 17 causes the article discharging device 20 to discharge the amount of articles A to be packaged in one bag W. As shown in FIG.
　より詳細には、制御部１７は、受け部材４０の第１接触部１８ｃ及び第２接触部１９ｃがフィルム筒ＦＴの外面に接触し、第１シールジョー５６及び第２シールジョー５７がフィルム筒ＦＴに接触する前に振動動作を開始する。振動動作では、制御部１７が、鉛直移動機構５５の鉛直移動モータ５９に所定の振幅での正転及び逆転を繰り返させる。これにより、架台５１が鉛直方向Ｖにおいて往復駆動するため、横シール機構１５の第１シールジョー５６、第２シールジョー５７、及び受け部材４０は、鉛直方向Ｖに振動する。これにより、第１動作が完了する前のフィルム筒ＦＴ内の物品Ａに振動が与えられる。 More specifically, the controller 17 causes the first contact portion 18c and the second contact portion 19c of the receiving member 40 to contact the outer surface of the film tube FT, and the first sealing jaw 56 and the second sealing jaw 57 to contact the film tube FT. start the vibrating motion before contacting the In the vibration operation, the control unit 17 causes the vertical movement motor 59 of the vertical movement mechanism 55 to repeat forward and reverse rotations with a predetermined amplitude. As a result, the pedestal 51 is driven to reciprocate in the vertical direction V, so that the first sealing jaw 56, the second sealing jaw 57, and the receiving member 40 of the horizontal sealing mechanism 15 vibrate in the vertical direction V. As shown in FIG. As a result, the article A in the film tube FT is vibrated before the first operation is completed.
　同時に、水平移動機構５４は、フィルム筒ＦＴを挟み込むまで第１シールジョー５６及び第２シールジョー５７を水平方向Ｈに移動させる。 At the same time, the horizontal movement mechanism 54 moves the first sealing jaw 56 and the second sealing jaw 57 in the horizontal direction H until the film tube FT is sandwiched.
　フィルム筒ＦＴを挟み込んだ第１シールジョー５６及び第２シールジョー５７は、フィルム筒ＦＴを押圧しながら、フィルム筒ＦＴに熱を加えて横シールする。この時、フィルム筒ＦＴの横シールされた部分である横シール部の下方には、物品Ａが包装された袋Ｗが作られる。次に、第１シールジョー５６又は第２シールジョー５７に設けられた可動ナイフが、横シール部を水平方向Ｈに切断して、第２フェーズが終了する。横シール部が切断されると、袋Ｗは、上方のフィルム筒ＦＴから切り離されて落下する。 The first sealing jaw 56 and the second sealing jaw 57 sandwiching the film tube FT press the film tube FT while applying heat to the film tube FT to laterally seal it. At this time, a bag W in which the article A is packaged is formed below the laterally sealed portion of the film tube FT. Next, the movable knife provided on the first sealing jaw 56 or the second sealing jaw 57 cuts the horizontal sealing portion in the horizontal direction H, and the second phase ends. When the lateral seal portion is cut, the bag W is separated from the upper film tube FT and dropped.
　制御部１７は、第１動作が完了するまでに、鉛直移動機構５５に、横シール機構１５に加えている振動を停止させ、振動動作を終了する。 The control unit 17 causes the vertical movement mechanism 55 to stop the vibration applied to the horizontal sealing mechanism 15 by the time the first operation is completed, and ends the vibration operation.
　ここで、第１動作が「完了する」時とは、挟み込んだフィルム筒ＦＴに熱を加えて横シールをした第１シールジョー５６及び第２シールジョー５７が、互いに離間を開始する直前を意味する。 Here, the time when the first operation is "completed" means just before the first sealing jaw 56 and the second sealing jaw 57, which have laterally sealed the sandwiched film tube FT by applying heat, start to separate from each other. do.
　上述したように、受け部材４０の第１接触部１８ｃ及び第２接触部１９ｃは、第１シールジョー５６及び第２シールジョー５７がフィルム筒ＦＴに接触する前に、フィルム筒ＦＴの外面に接触している。このため、第１接触部１８ｃ及び第２接触部１９ｃは、第１シールジョー５６及び第２シールジョー５７がフィルム筒ＦＴを挟み込む前にフィルム筒ＦＴを挟み込み、フィルム筒ＦＴ内部を落下する物品Ａを受け止めることができる。振動動作においては、受け部材４０も、鉛直方向Ｖに振動するため、受け部材４０に受け止められている物品Ａにも振動が与えられる。 As described above, the first contact portion 18c and the second contact portion 19c of the receiving member 40 contact the outer surface of the film tube FT before the first sealing jaw 56 and the second sealing jaw 57 contact the film tube FT. are doing. Therefore, the first contact portion 18c and the second contact portion 19c sandwich the film tube FT before the first sealing jaws 56 and the second sealing jaws 57 sandwich the film tube FT. can accept In the vibrating operation, the receiving member 40 also vibrates in the vertical direction V, so that the article A received by the receiving member 40 is also vibrated.
　なお、製袋包装機１０は、第２フェーズにおいて、振動動作を開始する前にしごき動作を行う。しごき動作は、フィルム筒ＦＴの内面に付着する物品Ａ等を落下させて横シール部における物品Ａ等の噛み込みを抑制するための動作である。しごき動作において、制御部１７は、鉛直移動機構５５に横シール機構１５を下方に所定距離移動させた後、元の高さへ戻させる（図７参照）。製袋包装機１０は、しごき動作を行わなくてもよい。 In the second phase, the bag making and packaging machine 10 performs the squeezing operation before starting the vibrating operation. The squeezing operation is an operation for dropping the article A or the like adhering to the inner surface of the film tube FT to prevent the article A or the like from being caught in the lateral seal portion. In the squeezing operation, the control unit 17 causes the vertical movement mechanism 55 to move the horizontal sealing mechanism 15 downward by a predetermined distance, and then return it to its original height (see FIG. 7). The form-fill-seal machine 10 does not have to perform the squeezing operation.
　（４－２）第２動作
　第１動作が完了すると、制御部１７は、第２動作を開始する。第２動作で、制御部１７は、水平移動機構５４に、第１シールジョー５６及び第２シールジョー５７を第１フェーズの開始時と同様に、フィルム筒ＦＴに接触しない位置で互いに離間するように水平方向Ｈに移動させる。同時に、制御部１７は、鉛直移動機構５５に、第１シールジョー５６及び第２シールジョー５７の鉛直方向Ｖにおける位置を、第１フェーズの開始時における位置まで戻させる。これにより、第２動作及びサイクル動作が完了する。 (4-2) Second Operation When the first operation is completed, the control section 17 starts the second operation. In the second operation, the controller 17 instructs the horizontal movement mechanism 54 to move the first sealing jaw 56 and the second sealing jaw 57 away from each other at a position where they do not come into contact with the film tube FT, as at the start of the first phase. in the horizontal direction H. At the same time, the control unit 17 causes the vertical movement mechanism 55 to return the positions of the first sealing jaw 56 and the second sealing jaw 57 in the vertical direction V to the positions at the start of the first phase. This completes the second operation and cycle operation.
　製袋包装機１０は、以上のサイクル動作を繰り返すことで、物品Ａが包装された袋Ｗを連続的に製造することができる。 The bag-making and packaging machine 10 can continuously manufacture bags W in which articles A are packaged by repeating the above cycle operation.
　振動動作を開始するタイミングは、第２フェーズの開始（第１接触部１８ｃ及び第２接触部１９ｃがフィルム筒ＦＴと接触した時）以後、第１動作が完了する前までであれば限定されない。 The timing of starting the vibration operation is not limited as long as it is after the start of the second phase (when the first contact portion 18c and the second contact portion 19c contact the film tube FT) and before the completion of the first operation.
　振動動作における振幅、周期、振動回数等のパラメータは、物品Ａの重量や形状、フィルムＦの材質、袋Ｗの形状等に基づいて適宜設定される。振動動作における振幅は、例えば、１０ミリ以上５０ミリ以下程度とすることができる。振動周期は、例えば、５０ミリ秒以上１００ミリ秒以下程度とすることができる。振動回数は、例えば、１回以上１０回以下程度とすることができる。 Parameters such as the amplitude, period, and number of vibrations in the vibrating motion are appropriately set based on the weight and shape of the article A, the material of the film F, the shape of the bag W, and the like. The amplitude of the vibrating motion can be, for example, about 10 mm or more and 50 mm or less. The vibration period can be, for example, about 50 milliseconds or more and 100 milliseconds or less. The number of times of vibration can be, for example, about 1 time or more and 10 times or less.
　（５）特徴
　（５－１）
　製袋包装機１０は、物品排出装置２０から排出された物品Ａを、フィルムＦを筒状に成形した袋Ｗに包装する。製袋包装機１０は、横シール機構１５と、移動機構１６と、制御部１７とを備える。横シール機構１５は、搬送される方向に対して交差する方向（水平方向Ｈ）からフィルムＦを挟み、シールする第１動作を行う。移動機構１６は、横シール機構１５を移動させる。制御部１７は、移動機構１６を制御し、第１動作が完了する前に横シール機構１５を振動させ、フィルム筒ＦＴ内の物品Ａに対して振動を与える振動動作を実行させる。 (5) Features (5-1)
The bag-making and packaging machine 10 packages the article A discharged from the article discharging device 20 in a bag W formed by forming a film F into a cylindrical shape. The bag making and packaging machine 10 includes a horizontal sealing mechanism 15 , a moving mechanism 16 and a control section 17 . The horizontal sealing mechanism 15 performs a first operation of sandwiching and sealing the film F from a direction (horizontal direction H) intersecting the conveying direction. The moving mechanism 16 moves the lateral sealing mechanism 15 . The control unit 17 controls the moving mechanism 16 to vibrate the horizontal sealing mechanism 15 before the completion of the first operation, and causes the article A in the film tube FT to vibrate.
　製袋包装機１０では、制御部１７が振動動作を実行する行うことで、第１動作が完了する前のフィルム筒ＦＴ内の物品Ａに振動が与えられる。これにより、第１動作の完了前に、横シール機構１５の下流側（鉛直方向Ｖにおける下方）にある物品Ａをお互いの隙間を詰めながら下方に向かって移動させられるため、横シール機構１５より下流側においても物品Ａの充填率を高めることができる。 In the bag making and packaging machine 10, the control unit 17 executes the vibrating operation, thereby vibrating the article A in the film tube FT before the first operation is completed. As a result, before the first operation is completed, the articles A located downstream of the horizontal sealing mechanism 15 (below in the vertical direction V) can be moved downward while closing the gap between them. The packing rate of the articles A can be increased also on the downstream side.
　また、製袋包装機１０では、第１動作中に振動動作が行われる。このため、第１動作とは別に物品Ａに振動を与える動作を行う場合と比べて、生産能力を下げることなく物品Ａの充填率を高めることができる。 Also, in the bag making and packaging machine 10, a vibrating operation is performed during the first operation. Therefore, compared to the case where the action of vibrating the article A is performed separately from the first action, the filling rate of the article A can be increased without lowering the production capacity.
　さらに、製袋包装機１０では、第１動作において横シール機構１５を移動させるための移動機構１６を用いて振動動作が実現される。このため、シェーカーのような物品Ａに振動を与えるための装置を特別に設ける必要が無いため、包装機の製造コストを低く抑えながら物品Ａの充填率を高めることができる。 Furthermore, in the bag making and packaging machine 10, a vibrating operation is realized using the moving mechanism 16 for moving the horizontal sealing mechanism 15 in the first operation. Therefore, it is not necessary to provide a special device such as a shaker for applying vibrations to the articles A, so that the packing rate of the articles A can be increased while the manufacturing cost of the packaging machine is kept low.
　（５－２）
　制御部１７は、振動動作において、移動機構１６に横シール機構１５を鉛直方向Ｖで往復駆動させる。 (5-2)
The control unit 17 causes the moving mechanism 16 to reciprocate the horizontal sealing mechanism 15 in the vertical direction V during the vibration operation.

　受け部材４０は、横シール機構１５の上方において横シール機構１５に一体的に配置され、フィルム筒ＦＴの外面と接触してフィルム筒ＦＴの内部を落下する物品Ａを受け止める。制御部１７は、振動動作において、移動機構１６に、横シール機構１５とともに受け部材４０を振動させる。 (5-3)
The receiving member 40 is arranged integrally with the horizontal sealing mechanism 15 above the horizontal sealing mechanism 15, and receives the article A falling inside the film tube FT in contact with the outer surface of the film tube FT. The control unit 17 causes the moving mechanism 16 to vibrate the receiving member 40 together with the horizontal sealing mechanism 15 in the vibrating operation.
　製袋包装機１０では、振動動作において、横シール機構１５とともに受け部材４０も振動させるため、受け部材４０に受け止められている物品Ａについても振動が与えられる。このため、横シール機構１５の上流側（鉛直方向Ｖにおける上方）及び下流側の両側において効果的に物品Ａの充填率を高めることができる。 In the form-fill-seal machine 10, since the horizontal sealing mechanism 15 and the receiving member 40 are also vibrated during the vibrating operation, the article A received by the receiving member 40 is also vibrated. Therefore, it is possible to effectively increase the packing rate of the articles A on both the upstream side (upper side in the vertical direction V) and the downstream side of the horizontal sealing mechanism 15 .
　（５－４）
　横シール機構１５は、第１動作においてフィルム筒ＦＴを挟む第１シールジョー５６及び第２シールジョー５７を有する。 (5-4)

The receiving member 40 contacts the outer surface of the film tube FT before the first sealing jaw 56 and the second sealing jaw 57 contact the film tube FT in the first operation. The control section 17 starts the vibration operation before the receiving member 40 contacts the outer surface of the film tube FT and the first sealing jaw 56 and the second sealing jaw 57 contact the film tube FT.
　（５－６）

The moving mechanism 16 has a vertical moving motor 59 that drives the horizontal sealing mechanism 15 to rotate. In the vibrating operation, the control unit 17 causes the moving mechanism 16 to rotate the vertical moving motor 59 forward and backward to vibrate the horizontal sealing mechanism 15 .

The control unit 17 may cause the vertical movement mechanism 55 to move the horizontal sealing mechanism 15 slightly upward to inflate the bag W (browsing operation) before the first operation is completed. At this time, the control unit 17 vibrates the first sealing jaw 56, the second sealing jaw 57, and the receiving member 40 of the horizontal sealing mechanism 15, which move upward in the vertical movement mechanism 55, thereby increasing the filling rate of the article A. can be further enhanced.
