Description

本発明は、縦型製袋充填包装機の紙送り装置に関する。   The present invention relates to a paper feeding device for a vertical bag making filling and packaging machine.

縦型製袋充填包装機は、紙送り装置により、フィルムロールから引き出された帯状包装材を製筒器により筒状に成形し、筒内に被包装品の充填を行い、縦シール、横シールを施し、横シールの中間で切断することにより内部に被包装品が充填された袋包装体を製造する。紙送り装置は１袋分の長さの包装材を間欠又は連続に引き出す機能を備えている。包装材の引き出しにあたっては、弛みや過度の引っ張りがないように、即ち適度なテンションを保った状態で行われる。   A vertical bag making and packaging machine uses a paper feeder to form a strip of packaging material drawn from a film roll into a cylinder using a cylinder making machine, fills the inside of the cylinder with the product to be packaged, and creates vertical and horizontal seals. The bag package body in which the product to be packaged is filled is manufactured by cutting in the middle of the horizontal seal. The paper feeding device has a function of pulling out the packaging material of one bag length intermittently or continuously. When pulling out the packaging material, it is performed so as not to be loosened or excessively pulled, that is, in a state where an appropriate tension is maintained.

紙送り装置には、フィルムロールから引き出されたシート状のフィルムを２本のローラで挟み込んで搬送するピンチローラ搬送方式を採用するものがある（特許文献１、特許文献２、特許文献３、特許文献４参照）。この方法は、製筒器より上流のピンチローラと製筒器より下流のベルトの協働により１袋分の長さの包装材を引き出す紙送り装置を備えている。
特許文献１、特許文献２の縦型製袋充填包装機は、製筒器より上流に位置するピンチローラが、１袋分の長さの包装材を引き出し、製筒器より下流に位置するベルトが、ピンチローラよりやや早く動くことで引き出された包装材を適度なテンションを保ちながら送り出す紙送り装置を備えている。
特許文献３の縦型製袋充填包装機は、製筒器より上流に位置するピンチローラと製筒器より下流に位置するベルトが、が互いに積極的に協働すること即ち速度同期して動き、ベルトがわずかに遅く停止することで、適度なテンションを保ちつつ１袋分の長さの包装材を引き出す紙送り装置を備えている。
特許文献４の縦型製袋充填包装機は、製筒器より下流に位置するベルトが、１袋分の長さの包装材を引き出し、製筒器より上流に位置するピンチローラは、その下流に位置するテンションレバーの状態に応じて動作することで、適度なテンションを保つ紙送り装置を備えている。 Some paper feeding apparatuses employ a pinch roller conveyance system in which a sheet-like film drawn from a film roll is sandwiched and conveyed by two rollers (Patent Document 1, Patent Document 2, Patent Document 3, Patent) Reference 4). This method includes a paper feeding device that draws out a packaging material having a length corresponding to one bag by cooperation of a pinch roller upstream from the cylinder making machine and a belt downstream from the cylinder making machine.
In the vertical bag making and filling machine of Patent Literature 1 and Patent Literature 2, a pinch roller located upstream from the cylinder making machine pulls out the packaging material of one bag length and is located downstream from the cylinder making machine. However, it is equipped with a paper feeding device that feeds the packaging material drawn out by moving slightly faster than the pinch roller while maintaining an appropriate tension.
In the vertical bag-filling and packaging machine of Patent Document 3, the pinch roller located upstream from the cylinder making machine and the belt located downstream from the cylinder making machine actively cooperate with each other, that is, move in synchronism with each other. The paper feeding device that pulls out the packaging material of one bag length while maintaining an appropriate tension is provided by stopping the belt slightly late.
In the vertical bag-filling and packaging machine of Patent Document 4, the belt located downstream from the cylinder making machine pulls out the packaging material for the length of one bag, and the pinch roller located upstream from the cylinder making machine is downstream thereof. A paper feeding device that maintains an appropriate tension is provided by operating according to the state of the tension lever located in the position.

上記のような２本のローラで挟み込んで搬送するピンチローラを採用した場合、挟み込みローラの挟圧の調整が必要である。また、ピンチローラを採用する場合は、２本のローラで挟み込まれたフィルムのＸ・Ｙ・Ｚ方向の位置などを精確に調整しないと、搬送されるフィルムに皺が発生するおそれがある。また、フィルムの材質と寸法が変更する度に、ピンチローラの挟圧、フィルムの位置などを調整する必要がある。また、フィルムの両端はスリッターにより切断されるが、フィルムとして粗悪な材質のフィルムが使われた場合、切断後のフィルムがウェブ状となる場合がある。このようにウェブ状になっているフィルムをピンチローラでフィルム全面と接触しながら搬送すると、蛇行が発生するおそれがある。   When a pinch roller that is sandwiched and conveyed by the two rollers as described above is used, it is necessary to adjust the sandwiching pressure of the sandwiching roller. When a pinch roller is used, wrinkles may occur in the conveyed film unless the position in the X, Y, and Z directions of the film sandwiched between the two rollers is accurately adjusted. Further, it is necessary to adjust the pinch roller clamping pressure, the film position, etc., whenever the film material and dimensions change. Moreover, although the both ends of a film are cut | disconnected by a slitter, when the film of a bad material is used as a film, the film after cutting | disconnection may become a web form. If the web-like film is conveyed while being in contact with the entire surface of the film with a pinch roller, meandering may occur.

ピンチローラを用いない紙送り装置に、特許文献５に示すような方法がある。これは、製筒器より下流に位置するベルト又はローラが、１袋分の長さの包装材を引き出し、包装材の搬送路にあるテンション検出手段によって検出された包装材のテンション状態に応じて、フィルムロールの装着されている軸をモータで駆動し、繰出しを行うことで適度なテンションを保つものである。つまり製筒器上流にテンション検出手段及びテンション付与手段を備え、製筒器下流に包装材搬送手段を備えた紙送り機構である。この方式は、ピンチローラ方式の持つ弱点、即ちピンチローラの位置調整の煩雑さや蛇行発生の危険がなく、良好な包装材の搬送が実現するという目的を、一定程度解決している。   As a paper feeding device that does not use a pinch roller, there is a method as shown in Patent Document 5. This is because the belt or roller located downstream from the cylinder making unit pulls out the packaging material of one bag length, depending on the tension state of the packaging material detected by the tension detection means in the conveyance path of the packaging material. The shaft on which the film roll is mounted is driven by a motor and fed out to maintain an appropriate tension. That is, the paper feeding mechanism includes a tension detecting unit and a tension applying unit upstream of the cylinder making unit, and a packaging material conveying unit downstream of the cylinder making unit. This method solves to some extent the weak point of the pinch roller method, that is, the trouble of adjusting the position of the pinch roller and the risk of occurrence of meandering, and realizing good conveyance of the packaging material.

しかしながら、この方式は１袋分の長さの包装材の引き出しを製筒器下流に包装材搬送手段がすべて行うため、その負担が非常に重い。テンション付与機構により適度なテンションが保たれているが、包装材がフィルムロールから引き出されてから、縦シール装置及び横シール装置に到達するまでの間は、フィルムの搬送を案内する複数のガイドロールと製筒器が存在しており、その走行抵抗はかなりのものとなる。また、筒状に成形されてからは、製袋充填筒に巻き付いた状態なので、その接触抵抗もかなりのものとなる。紙送り機構はこれらの走行抵抗に打ち勝ち一定寸法の包装材を確実に引き出すために紙送りベルトに密着性のある素材を使用し、包装材とベルトを密着させ、さらにバキューム吸着機構を設けるなどして、対処している（特許文献６参照）。また、駆動モータもトルクも大きいものを使用している。しかし、密着性の良い紙送りベルトは、紙送りベルトの摩耗が激しく寿命が短いという欠点がある。   However, this method is very heavy because the packaging material conveying means performs all the drawing of the packaging material of one bag length downstream of the cylinder making machine. Although a moderate tension is maintained by the tension applying mechanism, a plurality of guide rolls for guiding the conveyance of the film from when the packaging material is pulled out from the film roll until it reaches the vertical sealing device and the horizontal sealing device. And there is a cylinder making machine, and its running resistance is considerable. Further, since it is wound around the bag making and filling cylinder after being formed into a cylindrical shape, its contact resistance is considerable. In order to overcome these running resistances and to reliably pull out packaging materials of a certain size, the paper feed mechanism uses a material that has adhesiveness to the paper feed belt, the packaging material and the belt are in close contact, and a vacuum suction mechanism is provided. (See Patent Document 6). Also, a drive motor having a large torque is used. However, a paper feed belt having good adhesion has a drawback that the paper feed belt is worn out and has a short life.

これに対する解決策として特許文献７や特許文献８による提案がなされている。これらの提案は、包装材に対する走行抵抗が特に大きい製筒器の上流部に副次的な紙送り装置として、バキューム吸着機構を備えたベルトを配置し動作させることによって、製筒器の下流に位置する主たる紙送り装置の負担を軽減させようとするものである。   As a solution to this, proposals in Patent Document 7 and Patent Document 8 have been made. In these proposals, a belt equipped with a vacuum suction mechanism is arranged and operated as a secondary paper feeder in the upstream part of the cylinder making machine, which has a particularly large running resistance against the packaging material, and is thus provided downstream of the cylinder making machine. It is intended to reduce the burden on the main paper feeding device located.

特許文献７の方法は、フィルムロール近傍にテンション付与手段を設け、製筒器を挟んで上流と下流にそれぞれバキュームベルトの紙送り手段を設け同一モータによって駆動する紙送り機構である。上流側の紙送り手段は、帯状包装材の仮面に位置するバキュームベルトであり、下流側紙送り手段は製袋充填筒の裏側に位置するバキュームベルトであり、それらを同一のモータで駆動している。簡易な機構により駆動モータが１つで済む利点はあるが、それゆえに以下に示す欠点を有する。まず、駆動モータが１つであり、特別な変速装置も設けていないことから、上流側紙送り手段と下流側紙送り手段は同速で動くこととなる。製筒器を挟んで上流側と下流側に紙送り手段があった場合、下流側の搬送量を多くしなければならないことは、特許文献１または特許文献２にも示されている周知の事項である。   The method of Patent Document 7 is a paper feed mechanism in which tension applying means is provided in the vicinity of a film roll, vacuum belt paper feed means are provided upstream and downstream of the cylinder making machine, and driven by the same motor. The upstream paper feeding means is a vacuum belt located on the mask surface of the belt-shaped packaging material, and the downstream paper feeding means is a vacuum belt located on the back side of the bag making and filling cylinder, and they are driven by the same motor. Yes. Although there is an advantage that only one drive motor is required by a simple mechanism, it has the following disadvantages. First, since there is one drive motor and no special transmission is provided, the upstream paper feeding means and the downstream paper feeding means move at the same speed. It is a well-known matter disclosed in Patent Document 1 or Patent Document 2 that if the paper feeding means is located on the upstream side and the downstream side across the cylinder making device, the downstream transport amount must be increased. It is.

特許文献７の方法を改良したものとして特許文献８の方法がある。これは、上流側の紙送り手段は、帯状包装材の下面に位置するバキュームベルトであり、下流側紙送り手段は製袋充填筒の裏側に位置するバキュームベルトであり、それぞれのバキュームベルトを別のモータで駆動し、下流側のバキュームベルトを上流側バキュームベルトより速く動かすものである。さらに上流側のバキュームベルトには、取付け位置を左右に回転させ蛇行修正の機構を組み込んだものである。   As an improvement of the method of Patent Document 7, there is a method of Patent Document 8. The upstream paper feeding means is a vacuum belt located on the lower surface of the belt-like packaging material, and the downstream paper feeding means is a vacuum belt located on the back side of the bag-filling cylinder. And the downstream vacuum belt is moved faster than the upstream vacuum belt. Further, the upstream vacuum belt incorporates a meandering correction mechanism by rotating the mounting position left and right.

特許文献７及び特許文献８の方法とも、下流側のバキュームベルトは、製袋充填筒の裏面に位置しているが、この方式は、製袋充填筒を挟んで一対のバキュームベルトを備える特許文献６のような方式に比べて以下の欠点を有する。背面から下方に向かって引き下げるため、包装充填筒表側に位置する、筒状包装材の合わせ目を引き離すような力が働きやすく、縦シールに悪影響を与えることになる。   In both methods of Patent Document 7 and Patent Document 8, the vacuum belt on the downstream side is located on the back surface of the bag making and filling cylinder, but this method includes a pair of vacuum belts sandwiching the bag making and filling cylinder. Compared with the system like 6, it has the following drawbacks. Since it pulls downward from the back surface, a force that pulls the seam of the cylindrical packaging material located on the front side of the packaging and filling cylinder is likely to work, which adversely affects the vertical seal.

The operation of the vertical bag making and packaging machine in which the present invention is implemented will be described with reference to FIG. FIG. 1 is a schematic perspective view of a vertical bag making filling and packaging machine. The belt-shaped packaging material Fw fed from the film roll Fr by the paper feeding means 5 and the paper feeding support means 6 and given the appropriate tension by the tension applying means 8 is guided by the guide roll 7 and After the edge portion is formed into a substantially closed cylindrical shape, the overlapped edge portion is subjected to a vertical seal by the vertical seal device 3 to be formed into a cylindrical packaging material Ft. A lateral seal device 5 is provided so that the article to be packaged is filled into the cylindrical packaging material Ft from above through the bag-filling cylinder 2 and crosses the cylindrical packaging material Ft at a position between the packaging product and the packaging product. A bag package Bp in which a product to be packaged is wrapped in a packaging bag is manufactured by performing a horizontal seal by cutting with a cutting blade (not shown) provided in the horizontal seal device in the middle of the horizontal seal. The The vertical bag making and filling machine of the present embodiment is an intermittent type machine that temporarily stops the lowering of the packaging tube Ft during vertical sealing and horizontal sealing.

本実施例の紙送り装置１０について、図１及び図２を用いて説明する。紙送り装置１０は、紙送り手段５と紙送り支援手段６とテンション付与手段８から構成される。紙送り手段５は、製筒器１の下流に位置し、製袋充填筒２を挟んで設置された一対の紙送りベルト５５から成る。製袋充填筒２を挟んで左右の紙送りベルト５５は別々のモータにより駆動される。紙送りベルト５５の構成について、右側の紙送りベルト５５を例として説明する。紙送りベルト５５は、密着性の良い弾性素材の無端ベルトであり、従動プーリー５２、駆動プーリー５３、テンションプーリー５４に支持されている。駆動プーリー５３には紙送り右サーボモータ５１が連結されている。また、紙送りベルト５５の表面には吸着孔が複数設けられ、ベルトの内側の従動プーリー５２、駆動プーリー５３、の間にバキュームボックス５６が設けられている。バキュームボックス５６はバキュームポンプ等の負圧発生装置（図示せず）と接続されており、ベルトが包装材を吸引保持することで、包装材とベルトのスリップを防ぎ、１袋分に相当する長さの包装材の正確な送り量を実現する。また、紙送り手段５は、製袋充填筒２を挟んで設置された一対の紙送りベルト５５なので、包装材の送り動作のときに筒状包装材の合わせ目を引き離すような力が働きくことなく良好な縦シールの形成に寄与することができる。   A paper feeding apparatus 10 according to this embodiment will be described with reference to FIGS. 1 and 2. The paper feeding device 10 includes a paper feeding means 5, a paper feeding support means 6, and a tension applying means 8. The paper feeding means 5 is composed of a pair of paper feeding belts 55 which are located downstream of the cylinder making machine 1 and are installed with the bag making and filling cylinder 2 interposed therebetween. The left and right paper feed belts 55 are driven by separate motors with the bag making and filling cylinder 2 interposed therebetween. The configuration of the paper feed belt 55 will be described using the right paper feed belt 55 as an example. The paper feed belt 55 is an endless belt made of an elastic material with good adhesion, and is supported by a driven pulley 52, a drive pulley 53, and a tension pulley 54. A paper feed right servo motor 51 is connected to the drive pulley 53. A plurality of suction holes are provided on the surface of the paper feed belt 55, and a vacuum box 56 is provided between the driven pulley 52 and the drive pulley 53 inside the belt. The vacuum box 56 is connected to a negative pressure generator (not shown) such as a vacuum pump, and the belt sucks and holds the packaging material, thereby preventing slipping of the packaging material and the belt, and a length corresponding to one bag. Realize accurate feed amount of packaging material. Further, since the paper feeding means 5 is a pair of paper feeding belts 55 placed between the bag making and filling cylinder 2, a force that separates the seam of the cylindrical packaging material acts during the packaging material feeding operation. This can contribute to the formation of a good vertical seal without any problems.

次に、紙送り支援手段６について説明する。紙送り支援手段６は製筒器２より上流でテンション付与手段８よりも下流に設置された紙送り支援ロール駆動サーボモータ６１により駆動される紙送り支援ロール６２である。紙送り支援ロールの詳細について図３を用いて説明する。紙送り支援ロール６２は回転自在なロールであり、回転軸に紙送り支援ロール用従動プーリー６４が取り付けられている。紙送り支援ロール用駆動プーリー６５は紙送り支援ロール駆動サーボモータ６１の回転軸に取り付けられている。紙送り支援ロール用従動プーリー６４と紙送り支援ロール用駆動プーリー６５の間には紙送り支援ロール駆動ベルト６３で連結されている。紙送り支援ロール駆動サーボモータ６１はブラケット６６により機械フレーム（図示せず）に取り付けられている。紙送り支援ロール６２の周面には摩擦係数の高いシリコンゴムが巻き付けられており、帯状包装材Ｆｗがスリップしないようになっている。紙送り支援ロール６２は、紙送り手段５の包装材搬送速度と同期または略同期した制御がなされる。これにより、紙送り手段５の負担を軽減する。   Next, the paper feed support means 6 will be described. The paper feed support means 6 is a paper feed support roll 62 driven by a paper feed support roll drive servo motor 61 installed upstream of the cylinder making device 2 and downstream of the tension applying means 8. Details of the paper feed support roll will be described with reference to FIG. The paper feed support roll 62 is a rotatable roll, and a paper feed support roll driven pulley 64 is attached to the rotation shaft. The paper feed support roll drive pulley 65 is attached to the rotation shaft of the paper feed support roll drive servomotor 61. A paper feed support roll drive belt 63 is connected between the paper feed support roll driven pulley 64 and the paper feed support roll drive pulley 65. The paper feed assist roll drive servomotor 61 is attached to a machine frame (not shown) by a bracket 66. A silicon rubber having a high friction coefficient is wound around the peripheral surface of the paper feed support roll 62 so that the belt-shaped packaging material Fw does not slip. The paper feed support roll 62 is controlled in synchronization with or substantially in synchronization with the packaging material transport speed of the paper feed means 5. Thereby, the burden of the paper feeding means 5 is reduced.

次に、テンション付与手段８について図１及び図２を用いて説明する。テンション付与手段８は、紙送り手段５と紙送り支援手段６による１袋分に相当する長さの包装材の送りを行うことにともなう包装材の弛みや伸びを防ぎ、適度なテンションを保つことを目的とするものである。テンション検出レバー８２の動きの変化及び位置の状態に応じて、フィルムロールＦｒが装着されている巻取り軸８１の回転を制御するよう構成されている。テンション検出レバー８２は、機械フレーム（図示せず）に揺動自在に取り付けられており、テンション検出レバー回動軸８５が包装材の動きに応じて回動することにより揺動する。テンション検出レバー８２にはガイドロール７が２本取り付けられており、帯状包装材Ｆｗが、機械フレーム（図示せず）に回転自在に固定されたガイドロール７とテンション検出レバー８２に回転自在に固定されたガイドロール７とを交互に経由するように掛け渡される。これにより包装材の送りがあれば、テンション検出レバー８２は上方に揺動し、包装材の送りが停止すると自重により下方へ揺動する。テンション検出レバー回動軸８５には、テンションレバー位置測定ロータリーエンコーダ８４が取り付けられており、テンション検出レバー８２の動きの変化及び位置を把握する。巻取り軸８１には巻取り軸駆動サーボモータ８３が設けられており、包装材の動き即ちテンション検出レバー８２の動きに応じて、加減速または停止することで、テンション検出レバー８２を一定の位置に保つよう制御される。テンション検出レバー８２が一定の位置に保たれていれば、包装材には弛みや伸びが生じない。   Next, the tension applying means 8 will be described with reference to FIGS. The tension applying means 8 prevents looseness and elongation of the packaging material due to the feeding of the packaging material corresponding to one bag by the paper feeding means 5 and the paper feeding support means 6 and maintains an appropriate tension. It is intended. The rotation of the winding shaft 81 on which the film roll Fr is mounted is controlled in accordance with the change in the movement of the tension detection lever 82 and the state of the position. The tension detection lever 82 is swingably attached to a machine frame (not shown), and swings when the tension detection lever rotating shaft 85 rotates according to the movement of the packaging material. Two guide rolls 7 are attached to the tension detection lever 82, and the belt-like packaging material Fw is rotatably fixed to the guide roll 7 and the tension detection lever 82 which are rotatably fixed to a machine frame (not shown). The guide rolls 7 are passed over alternately. Thus, if the packaging material is fed, the tension detection lever 82 swings upward, and when the packaging material feed stops, swings downward due to its own weight. A tension lever position measurement rotary encoder 84 is attached to the tension detection lever rotation shaft 85 to grasp the change and position of the movement of the tension detection lever 82. The take-up shaft 81 is provided with a take-up shaft drive servo motor 83, which is accelerated or decelerated or stopped according to the movement of the packaging material, that is, the movement of the tension detection lever 82, thereby moving the tension detection lever 82 at a certain position. Controlled to keep on. If the tension detection lever 82 is kept at a certain position, the packaging material will not be loosened or stretched.

紙送り手段５と紙送り支援手段６による包装材の送り動作について図４を用いて説明する。図４は、紙送り手段５の包材搬送速度と紙送り支援手段６の包材搬送速度の関係をグラフにしたものである。図４（ａ）は紙送り手段の包材搬送速度９１を示したものであり、図４（ｂ）は、紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１に同期して制御された場合を示したものであり、図４（ｃ）は、紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１より早く略同期して制御された場合を示したものであり、図４（ｄ）は、紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１より遅く略同期して制御された場合を示したものである。本実施例の縦型製袋充填包装機は、縦シール及び横シール時に包装筒Ｆｔの降下を一時停止する間欠型のものであるので、図４（ａ）に示すように包装材の搬送速度は、紙送り時間９０の間の加速時間９３に停止状態から紙送り手段の包装材搬送速度９１まで加速し、定速送り時間９４の間を一定速で送り、減速時間９５の間にとなり包装材搬送速度９１から減速して停止するパターンとなる。紙送り支援手段６は、紙送り手段５が行う包装材の送りを支援し、負担を軽減するためのものなので、その包装材の送り動作は紙送り手段の包材搬送速度９１に同期または略同期したものになる。同期させるか略同期させるかは、使用する包装材の材質、製造する袋の大きさ、包装能力等の包装条件に応じて設定できるよう構成されている。   The packaging material feeding operation by the paper feeding means 5 and the paper feeding support means 6 will be described with reference to FIG. FIG. 4 is a graph showing the relationship between the packaging material conveyance speed of the paper feeding means 5 and the packaging material conveyance speed of the paper feeding support means 6. 4A shows the packaging material conveyance speed 91 of the paper feeding means, and FIG. 4B shows that the packaging material conveyance speed 92 of the paper feeding support means is changed to the packaging material conveyance speed 91 of the paper feeding means. FIG. 4 (c) shows a case where the packaging material conveyance speed 92 of the paper feeding support means is controlled almost synchronously earlier than the packaging material conveyance speed 91 of the paper feeding means. FIG. 4 (d) shows a case where the packaging material conveyance speed 92 of the paper feeding support means is controlled slower and substantially in synchronization with the packaging material conveyance speed 91 of the paper feeding means. is there. Since the vertical bag making and packing machine of the present embodiment is an intermittent type that temporarily stops the lowering of the packaging tube Ft during vertical sealing and horizontal sealing, as shown in FIG. Is accelerated from the stop state to the wrapping material conveyance speed 91 of the paper feeding means during the acceleration time 93 during the paper feeding time 90, and is fed at a constant speed during the constant speed feeding time 94, and becomes during the deceleration time 95 during packaging. The pattern is decelerated from the material conveyance speed 91 and stopped. Since the paper feeding support means 6 is for supporting the feeding of the packaging material performed by the paper feeding means 5 and reducing the burden, the feeding operation of the packaging material is synchronized or substantially synchronized with the packaging material conveyance speed 91 of the paper feeding means. It will be synchronized. Whether to synchronize or substantially synchronize can be set according to the packaging conditions such as the material of the packaging material to be used, the size of the bag to be manufactured, and the packaging capacity.

紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１に同期して制御する場合、図４（ｂ）に示すように、紙送り支援手段の包材搬送速度９２と紙送り手段の包材搬送速度９１が等しく、紙送り時間９０、加速時間９３、定速時間９４、減速時間９５を同じにしているので、紙送り手段５と紙送り支援手段６の包装材の搬送速度のパターンはまったく同じ即ち同期している。次に略同期であるが、略同期とは紙送り時間９０、加速時間９３、定速時間９４、減速時間９５の長さを同じにして、定速時間９４の間の紙送り支援手段の包材搬送速度９２を紙送り手段の包材搬送速度９１より速くまたは遅くすることを意味する。図４（ｃ）に紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１より早く略同期させた場合の速度パターンを、図４（ｄ）に紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１より遅く略同期して制御された場合の速度パターンを示す。   When the packaging material conveyance speed 92 of the paper feeding support means is controlled in synchronization with the packaging material conveyance speed 91 of the paper feeding means, as shown in FIG. 4 (b), the packaging material conveyance speed 92 of the paper feeding assistance means and the paper Since the packaging material conveyance speed 91 of the feeding means is equal and the paper feeding time 90, the acceleration time 93, the constant speed time 94, and the deceleration time 95 are the same, the paper feeding means 5 and the paper feeding support means 6 carry the packaging material. The speed pattern is exactly the same or synchronized. Next, although it is substantially synchronous, the substantially synchronous means that the paper feed time 90, the acceleration time 93, the constant speed time 94, and the deceleration time 95 have the same length, and the paper feed support means wraps during the constant speed time 94. This means that the material conveying speed 92 is made faster or slower than the packaging material conveying speed 91 of the paper feeding means. FIG. 4 (c) shows a speed pattern when the packaging material conveyance speed 92 of the paper feeding support means is substantially synchronized earlier than the packaging material conveyance speed 91 of the paper feeding means, and FIG. A speed pattern in the case where the material conveyance speed 92 is controlled substantially in synchronization with the paper feeding means slower than the packaging material conveyance speed 91 is shown.

紙送り支援手段６の紙送り手段５に対する同期、略同期の設定方法について図５を用いて説明する。本実施例では、縦型製袋充填包装機の表示入力装置上の同期係数の設定値９６の値により紙送り支援手段６の紙送り手段５に対する同期、略同期が設定される。同期係数の設定値９６は、紙送り支援手段６の紙送り手段５に対する同期の度合いを設定する数値である。同期係数の設定値９６の設定が１００％であれば、紙送り支援手段６は紙送り手段５に同期して動作するので図4（ｂ）に示した動作となる。同期係数の設定値９６の設定が１００％以外の値であれば紙送り支援手段６は紙送り手段５に略同期して動作する。１０１％以上の設定であれば、紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１より早く略同期されるので、図4（ｃ）で示した動作となる。９９％以下の設定であれば、紙送り支援手段の包材搬送速度９２が紙送り手段の包材搬送速度９１より遅く略同期されるので、図4（ｄ）で示した動作となる。   A method for setting the synchronization and substantially synchronization of the paper feeding support unit 6 with respect to the paper feeding unit 5 will be described with reference to FIG. In this embodiment, the synchronization of the paper feeding support means 6 with respect to the paper feeding means 5 is set according to the value of the synchronization coefficient set value 96 on the display input device of the vertical bag making filling and packaging machine. The setting value 96 of the synchronization coefficient is a numerical value for setting the degree of synchronization of the paper feed support means 6 with respect to the paper feed means 5. If the setting value 96 of the synchronization coefficient is 100%, the paper feed support means 6 operates in synchronism with the paper feed means 5, so that the operation shown in FIG. If the setting value 96 of the synchronization coefficient is a value other than 100%, the paper feed support means 6 operates substantially in synchronization with the paper feed means 5. If the setting is 101% or more, the packaging material conveyance speed 92 of the paper feeding support means is substantially synchronized faster than the packaging material conveyance speed 91 of the paper feeding means, so the operation shown in FIG. If the setting is 99% or less, the packaging material conveyance speed 92 of the paper feeding support means is slower than the packaging material conveyance speed 91 of the paper feeding means and is substantially synchronized, so the operation shown in FIG.

本実施例では、紙送り手段の包材搬送速度９１を加速時間９３と減速時間９５が等しく、定速時間９４がある台形のパターンとしたが、これに限らず、定速時間９４のない三角形でも、サインカーブ等の曲線のパターンでもよい。紙送り手段の包材搬送速度９１がどのようなパターンであっても、紙送り支援手段の包材搬送速度９２は紙送り手段の包材搬送速度９１に同期又は略同期して制御される。   In this embodiment, the packaging material conveyance speed 91 of the paper feeding means is a trapezoid pattern in which the acceleration time 93 and the deceleration time 95 are equal, and the constant speed time 94 is provided. However, it may be a curved pattern such as a sine curve. Regardless of the pattern of the packaging material conveyance speed 91 of the paper feeding means, the packaging material conveyance speed 92 of the paper feeding support means is controlled in synchronization with or substantially in synchronization with the packaging material conveyance speed 91 of the paper feeding means.

本実施例では、本発明が間欠型の縦型製袋充填包装機に適用された例を示したが、本発明は連続型の縦型製袋充填包装機にも適用できることは言うまでもない。連続型の縦型製袋充填包装機は、縦シール及び横シール時にも包装筒Ｆｔの降下を停止せずに包装筒降下中にシーラが近接し、包装筒の降下に同期してシーラも降下しつつ加熱、押圧しシールを実施し後離間する動作を行うものである。間欠型の縦型製袋充填包装機とは縦シール装置３と横シール装置４の形態がことなるが、紙送り装置１０については機構としては変わらないが、包装材の搬送動作はシール中も一時停止することなく連続して行われる。包装材の送りは一定速度で行われるものと変速しながら行われるものがある。変速しながら包装材の搬送するものは、シール中のみ定速でその他の区間は変速する。それぞれの場合の紙送り支援手段６の紙送り手段５に対する同期、略同期の例を図６と図７に示す。図６は、包装材の送りが一定速度で行われる場合を示す。図６（ａ）は、紙送り手段の包装材搬送速度９１を示している。図６（ｂ）は、紙送り支援手段の包装材搬送速度９２が紙送り手段の包装材搬送速度９１と同じ場合即ち同期の場合を示している。図６（ｃ）は、紙送り支援手段の包装材搬送速度９２が紙送り手段の包装材搬送速度９１より速い場合の略同期の場合を示している。図６（ｄ）は、紙送り支援手段の包装材搬送速度９２が紙送り手段の包装材搬送速度９１より遅い場合の略同期の場合を示している。図７は変速しながら包装材の搬送する場合の例を示している。図７（ａ）は、紙送り手段の包装材搬送速度９１を示している。図７（ｂ）は、紙送り支援手段の包装材搬送速度９２が紙送り手段の包装材搬送速度９１と同期の場合を示している。図７（ｃ）は、紙送り支援手段の包装材搬送速度９２が紙送り手段の包装材搬送速度９１より速い場合の略同期の場合を示している。図７（ｄ）は、紙送り支援手段の包装材搬送速度９２が紙送り手段の包装材搬送速度９１より遅い場合の略同期の場合を示している。   In the present embodiment, an example in which the present invention is applied to an intermittent type vertical bag making filling and packaging machine is shown, but it goes without saying that the present invention can also be applied to a continuous type vertical bag making filling and packaging machine. The continuous vertical bag making and filling machine does not stop the lowering of the packaging tube Ft even during vertical and horizontal sealing, the sealer comes close while the packaging tube descends, and the sealer also descends in synchronization with the lowering of the packaging tube However, heating and pressing are performed, sealing is performed, and then an operation of separating is performed. The intermittent vertical bag making and filling and packaging machine is different in the form of the vertical sealing device 3 and the horizontal sealing device 4, but the paper feeding device 10 does not change as a mechanism, but the conveyance operation of the packaging material is also performed during sealing. It is performed continuously without pausing. The packaging material may be fed at a constant speed or while being shifted. What is conveyed by the packaging material while shifting is shifted at a constant speed only during sealing, and the other sections are shifted. FIGS. 6 and 7 show examples of synchronization and substantially synchronization of the paper feeding support means 6 with respect to the paper feeding means 5 in each case. FIG. 6 shows a case where the packaging material is fed at a constant speed. FIG. 6A shows the packaging material conveyance speed 91 of the paper feeding means. FIG. 6B shows a case where the packaging material conveyance speed 92 of the paper feeding support means is the same as the packaging material conveyance speed 91 of the paper feeding means, that is, the case of synchronization. FIG. 6C shows a case in which the packaging material conveyance speed 92 of the paper feeding support means is substantially synchronized when the packaging material conveyance speed 91 of the paper feeding means is faster. FIG. 6D shows a case in which the packaging material conveyance speed 92 of the paper feeding support means is slower than the packaging material conveyance speed 91 of the paper feeding means. FIG. 7 shows an example in which the packaging material is conveyed while shifting. FIG. 7A shows the packaging material conveyance speed 91 of the paper feeding means. FIG. 7B shows a case where the packaging material conveyance speed 92 of the paper feeding support means is synchronized with the packaging material conveyance speed 91 of the paper feeding means. FIG. 7C shows a case in which the packaging material conveyance speed 92 of the paper feeding support means is substantially synchronized when the packaging material conveyance speed 91 of the paper feeding means is faster. FIG. 7D shows a case in which the packaging material conveyance speed 92 of the paper feeding support means is substantially synchronized when the packaging material conveyance speed 91 of the paper feeding means is slower.
