多列式自動包装機Multi-row automatic packaging machine
　本発明は、包装フィルム（包材）を用いて被包装材料（内容物）を自動的に充填包装する自動包装機の技術分野に属する。より詳細には、帯状の包装フィルムを複数条にスリットし、これら複数条にスリットされた包装フィルムを用いて包装袋を形成する多列式（多連式）の自動包装機に関する。 The present invention belongs to the technical field of an automatic packaging machine for automatically filling and packaging a material to be packaged (contents) using a packaging film (packaging material). More specifically, the present invention relates to a multi-row (multi-line) automatic packaging machine that slits a strip-shaped packaging film into a plurality of strips and forms a packaging bag using the packaging film slit into the strips.
　従来の多列（多連）式自動包装機は、例えば、特許文献１に記載されているように、幅広のシートフィルムに均一に印刷された巻取り状の包材を列数に応じてスリット→縦シール→横シール→被包装材料の充填→カットの各作業を連続的に行うように構成されている。 A conventional multi-row (multi-line) automatic packaging machine, for example, as described in Patent Document 1, slits a winding-like packaging material uniformly printed on a wide sheet film according to the number of rows. It is configured to perform each operation of → vertical seal → horizontal seal → filling of packaging material → cutting continuously.

　上述したように、多列式自動包装機によれば一度に多数のステイック状包装製品を自動包装できる利点を備えているが、包装製品のサイズ（長さ）を変更する場合は、サイズに合せて横シーラＹの上下の移動量を調節しなければならない。 As described above, the multi-row automatic packaging machine has the advantage that a large number of sticky package products can be automatically packaged at one time. However, when changing the size (length) of the package product, it is necessary to match the size. Therefore, the amount of vertical movement of the horizontal sealer Y must be adjusted.
　ところが、従来の自動包装機ではこの横シーラＹを上下作動する手段として回転クランク機構が用いられていて、袋の長さを変更する場合はこのクランクの回転半径を調節する必要があり、加えて、被包装材料の充填タイミングとカッタによるカットタイミングを、夫々回転歯車差動装置やタイミング設定カム等を用いてその都度調節する必要があって、その操作に時間と手間が掛って非常に面倒であった。 However, in the conventional automatic packaging machine, a rotating crank mechanism is used as means for moving the horizontal sealer Y up and down, and when changing the length of the bag, it is necessary to adjust the turning radius of the crank. Therefore, it is necessary to adjust the filling timing of the material to be wrapped and the cutting timing by the cutter each time using a rotary gear differential, a timing setting cam, etc., and this operation takes time and effort and is very troublesome. there were.
　また、上記の各調節作業を終えた後でも、しばらく試しシールを繰返してメジャー等で実寸法を図ったり、重量計で重量を図ったりしながら調節を繰返さないと、正しい包サイズと充填量を得ることができないから、調節作業が増々複雑化、長時間化してしまう問題があり、加えて、これ等調節のための試しシールによって多くの被包装材料や包材ＦＸが無駄に消費されてしまう問題もあって、その改善が望まれていた。 In addition, even after completing each adjustment above, repeat the test seal for a while and measure the actual dimensions with a measure or the like, or measure the weight with a scale, and repeat the adjustment to ensure the correct package size and filling amount. Since it cannot be obtained, there is a problem that the adjustment work becomes more complicated and takes a longer time. In addition, a lot of packaging materials and packaging materials FX are wasted due to the trial seal for the adjustment. There were problems and improvements were desired.
　このようなことから、本願出願人は、横シーラＹを上下作動する手段として回転クランク機構を用いることに代えて、特許文献２において、電動式の駆動モータと、横シーラＹに取り付けられた動滑車と、フレーム側に固定されている定滑車と、これらに巻き掛けられたタイミングベルト又はチェーン等と、により、横シーラＹを上下作動させることができるようにした技術を提案した。 For this reason, the applicant of the present application, instead of using a rotary crank mechanism as means for moving the horizontal sealer Y up and down, in Patent Document 2, an electric drive motor and a motion attached to the horizontal sealer Y are disclosed. A technology has been proposed in which the horizontal sealer Y can be moved up and down by a pulley, a fixed pulley fixed to the frame side, and a timing belt or chain wound around the pulley.
　特許文献２に記載の自動包装機によれば、ファイルムの送り速度や被包装材料の充填タイミング等から独立して、横シーラＹの上下動作を任意の速度に自由度を高く設定することができるため、包装製品のサイズ（長さ）を変更するような場合でも調整が容易で、調節作業の短縮化、被包装材料や包材ＦＸの無駄な消費を抑制できるものである。 According to the automatic packaging machine described in Patent Document 2, the vertical movement of the horizontal sealer Y can be set to an arbitrary speed with a high degree of freedom independently from the feeding speed of the film, the filling timing of the packaging material, and the like. Therefore, even when the size (length) of the packaged product is changed, the adjustment is easy, the adjustment work can be shortened, and wasteful consumption of the packaging material and the packaging material FX can be suppressed.
　しかしながら、特許文献２に記載の自動包装機では、縦シールする際に、縦シーラを包装フィルムの搬送面と直交する方向から接近して包装フィルムに接触させて縦シールを行った後、包装フィルムから退避させる進退機構（往復運動機構）が必要となっており、当該機構は複雑であると共に、振動・騒音などが比較的大きく高速化に適さない構成であり、更には、縦シールをしている間、包装フィルムの送り（搬送）を一時停止する必要があり、構成の簡略化や生産性の改善など、更なる改良が望まれているといった実情がある。 However, in the automatic packaging machine described in Patent Document 2, when performing vertical sealing, the vertical sealer is approached from the direction orthogonal to the conveyance surface of the packaging film and brought into contact with the packaging film to perform vertical sealing, and then the packaging film A reciprocating mechanism (reciprocating mechanism) that retreats from the center is required. The mechanism is complex and has a relatively large vibration and noise and is not suitable for high speed. During this time, it is necessary to temporarily stop the feeding (conveyance) of the packaging film, and there is a situation that further improvements are desired, such as simplification of the configuration and improvement of productivity.
　本発明は、上述した実情に鑑みなされたもので、簡単かつ低コストな構成でありながら、包装フィルムを一時停止することなく所定速度で連続的に送りながら、ステイック状包装製品を多列式に自動包装することができる多列式自動包装機を提供することを目的とする。 The present invention has been made in view of the above-described circumstances, and in a simple and low-cost configuration, while continuously feeding a packaging film at a predetermined speed without temporarily stopping the packaging, a multi-row type of sticky packaging products is provided. An object is to provide a multi-row automatic packaging machine capable of automatic packaging.

The vertical sealing belt 611 is disposed so as to be rotated in a direction along the conveyance direction of the packaging film F4.
　そして、縦シール用ベルト駆動ギヤ６１７には、図３（Ａ）に示すように、縦シール用ベルト駆動モータ６５が回転連結されていて、包装フィルムの送り速度（搬送速度）と同じ速度となるように、縦シール用ベルト駆動モータ６５の回転速度が制御されるようになっている。 As shown in FIG. 3 (A), the vertical seal belt drive motor 65 is rotationally connected to the vertical seal belt drive gear 617 and has the same speed as the feed speed (conveyance speed) of the packaging film. As described above, the rotational speed of the longitudinal seal belt drive motor 65 is controlled.
　このような構成のベルト式縦シールユニット６１によれば、フォーマー５の外周に略円筒状に巻き付けられた包装フィルムＦ４の両サイド（開放端）同士の重ね合わせ部Ｐを、電熱式のヒーター金具６１４により昇温されている縦シール用ベルト６１１を、フォーマー５の外周に押し付ける（図４（Ｃ）参照）ことで、縦シールを施すことができるが、このとき、縦シール用ベルト６１１は包装フィルムＦ４の搬送速度に合わせて回転駆動されるため、従来のように、縦シールの際に、包装フィルムの送り（搬送）を一時停止する必要がないため、生産能率を改善することができる。 According to the belt-type vertical seal unit 61 having such a configuration, the overlapping portion P on both sides (open ends) of the packaging film F4 wound around the outer periphery of the former 5 in a substantially cylindrical shape is used as an electric heater bracket. The vertical seal belt 611 heated by 614 can be pressed against the outer periphery of the former 5 (see FIG. 4C) to provide a vertical seal. At this time, the vertical seal belt 611 is wrapped. Since the film F4 is rotationally driven in accordance with the conveyance speed of the film F4, it is not necessary to temporarily stop the feeding (conveyance) of the packaging film at the time of vertical sealing, so that the production efficiency can be improved.
　また、本実施の形態に係るベルト式縦シールユニット６１は、所定に加熱したベルトを包装フィルムの搬送方向に沿って回転させて縦シールを施す構成であるので、従来のように、縦シールする際に、縦シーラを包装フィルムの搬送面と直交する方向から接近して包装フィルムに接触させて縦シールを行った後、包装フィルムから退避させるといった複雑な進退機構（往復運動機構）が不要であり、構成の簡略化を促進できると共に、振動や騒音等の低減、包装フィルムの搬送速度の高速化に貢献可能である。 Further, the belt-type vertical seal unit 61 according to the present embodiment is configured to perform vertical sealing by rotating a belt heated in a predetermined direction along the conveyance direction of the packaging film. There is no need for a complicated reciprocation mechanism (reciprocating mechanism) in which the vertical sealer is approached from the direction perpendicular to the conveyance surface of the packaging film and brought into contact with the packaging film for vertical sealing and then retracted from the packaging film. In addition, the simplification of the configuration can be promoted, and it is possible to contribute to the reduction of vibration and noise and the increase in the transport speed of the packaging film.
　なお、本実施の形態に係る３方ベルト式縦シール装置６では、図３（Ａ）～図３（Ｃ）に示すように、フォーマー５の直径方向のベルト式縦シールユニット６１を挟んで両側の左側に縦シール左側送りユニット６２と、右側に縦シール右側送りユニット６３と、が左右一対となって対面配設されている。 In the three-way belt type vertical seal device 6 according to the present embodiment, as shown in FIGS. 3A to 3C, both sides of the belt type vertical seal unit 61 in the diameter direction of the former 5 are sandwiched. A vertical seal left feed unit 62 on the left side and a vertical seal right feed unit 63 on the right side are arranged facing each other as a pair.
　本実施の形態において、縦シール左側送りユニット６２と縦シール右側送りユニット６３の少なくとも一方が、本発明に係る縦シール送りユニットに相当している。 In the present embodiment, at least one of the vertical seal left feed unit 62 and the vertical seal right feed unit 63 corresponds to the vertical seal feed unit according to the present invention.
　縦シール左側送りユニット６２（縦シール右側送りユニット６３）は、図３（Ｂ）に示すように、包装フィルムＦ４の搬送方向に沿った方向に回転される縦シール左側送り用ベルト６２１（縦シール右側送り用ベルト６３１）を備えて構成され、縦シール左側送り用ベルト６２１（縦シール右側送り用ベルト６３１）は、縦シール左側送り用ベルトプーリ６２２、６２３、６２４、６２５（縦シール右側送り用ベルトプーリ６３２、６３３、６３４、６３５）に巻き掛けられて、フォーマー５の外周に略円筒状に巻き付けられた包装フィルムＦ４を両サイドから押し付けるように構成されている。 As shown in FIG. 3B, the vertical seal left feed unit 62 (vertical seal right feed unit 63) is a vertical seal left feed belt 621 (vertical seal) that rotates in a direction along the conveyance direction of the packaging film F4. The vertical seal left-feed belt 621 (vertical seal right-feed belt 631) includes vertical seal left-feed belt pulleys 622, 623, 624, 625 (vertical seal right-feed belt 631). Belt-type pulleys 632, 633, 634, and 635), and the packaging film F4 wound around the outer periphery of the former 5 in a substantially cylindrical shape is pressed from both sides.
　そして、図３（Ａ）、（Ｂ）に示すように、縦シール左側送り用ベルトプーリ６２３（縦シール右側送り用ベルトプーリ６３３）には、電動式の縦シール送り用ベルト駆動モータ６６がそれぞれ連結されて回転駆動されるようになっている。 As shown in FIGS. 3A and 3B, the vertical seal left-feed belt pulley 623 (vertical seal right-feed belt pulley 633) includes an electric vertical seal feed belt drive motor 66, respectively. It is connected and rotationally driven.
　このような構成の縦シール左側送りユニット６２（縦シール右側送りユニット６３）によれば、縦シール左側送り用ベルト６２１（縦シール右側送り用ベルト６３１）が、フォーマー５の外周に略円筒状に巻き付けられた包装フィルムＦ４を両サイドから押し付けながら包装フィルムＦ４の搬送速度と同じ速度となるように回転駆動されるため、ベルト式縦シールユニット６１により縦シールが施される包装フィルムＦ４の搬送を補助（アシスト或いはガイド）することができ、円滑な包装フィルムの送り（搬送）の実現に貢献することができる。 According to the vertical seal left feed unit 62 (vertical seal right feed unit 63) having such a configuration, the vertical seal left feed belt 621 (vertical seal right feed belt 631) has a substantially cylindrical shape on the outer periphery of the former 5. Since the wrapped packaging film F4 is pressed from both sides so as to be rotated at the same speed as the transportation speed of the packaging film F4, the belt-type longitudinal seal unit 61 conveys the packaging film F4 subjected to longitudinal sealing. It can assist (assist or guide), and can contribute to the smooth feed (conveyance) of the packaging film.
　なお、ここでは、縦シール左側送りユニット６２と縦シール右側送りユニット６３の２つの縦シール送りユニットとして説明したが、これに限らず、縦シール送りユニットの数や配置されるフォーマー５の周方向位置などについては、包装フィルムＦ４の搬送補助（アシスト或いはガイド）を良好に行うことができるように、適宜に変更することができるものである。 Here, the vertical seal left feed unit 62 and the vertical seal right feed unit 63 have been described as two vertical seal feed units. However, the present invention is not limited to this, and the number of vertical seal feed units and the circumferential direction of the disposed former 5 are not limited thereto. About a position etc., it can change suitably so that conveyance assistance (assist or guide) of packaging film F4 can be performed favorably.
　上述のようにして縦シールが施されて略円筒状に成形された包装フィルムＦ５は、次に、内容物充填部の下側の横シールが施された後、被包装材料（内容物）が充填され、その後、内容物充填部の上側の横シールが施された一つの包装袋が連続している状態（Ｆ６）とされる。 The packaging film F5, which has been vertically sealed as described above and formed into a substantially cylindrical shape, is then subjected to a lateral seal on the lower side of the content filling portion, and then a material to be packaged (content). After that, one packaging bag having a lateral seal on the upper side of the content filling portion is continuously placed (F6).
　本実施の形態では、図１、図２に示すように、充填装置３が、横シール装置７が横シールを行うと同時、或は、その直後に、ホッパ２内の被包装材料を一定量だけシュート４に供給して、その下端口より、内容物充填部の下側が横シールされて上方開口の袋状にされた包装フィルムの内部に充填供給するように構成されている。 In this embodiment, as shown in FIGS. 1 and 2, a certain amount of the material to be packaged in the hopper 2 is filled with the filling device 3 at the same time as or after the transverse sealing device 7 performs the transverse sealing. Only the chute 4 is supplied, and the lower side of the content filling part is laterally sealed from the lower end of the chute 4 so as to fill and supply the inside of the packaging film formed in the bag shape of the upper opening.
　また、横シール装置７は、上記充填装置３による被包装材料の充填が完了すると、横シーラ７Ｘ，７Ｙが、内容物充填部の下側の横シールを挾持した状態のまま、横シール上下機構１４によって１パック分（１内容物充填部分）だけ下方に移動して、各包装フィルムＦ５を１パック分だけ下方に移動し、その後、横シーラ７Ｘ，７Ｙを左右に開いて挾持を解き、その状態のまま元の横シール位置（内容物充填部の上側の横シール位置）に復帰上昇する仕組に成っている。 Further, when the filling of the material to be packaged by the filling device 3 is completed, the horizontal seal device 7 has a horizontal seal up-and-down mechanism with the horizontal sealers 7X and 7Y holding the horizontal seal below the contents filling portion. 14 is moved downward by one pack (one content filling portion), each packaging film F5 is moved downward by one pack, and then the horizontal sealers 7X and 7Y are opened to the left and right to release the grip. It is structured to return and rise to the original lateral seal position (the lateral seal position on the upper side of the content filling portion) in the state.
　すなわち、横シール装置７は、所定速度で連続搬送される包装フィルムに同期して上下動して、包装袋の下側部分に対応する場所に横シールを施した後、包装袋の上側部分に対応する場所に横シールを施すように構成されている。 That is, the horizontal sealing device 7 moves up and down in synchronization with the packaging film continuously conveyed at a predetermined speed, and after performing horizontal sealing at a location corresponding to the lower portion of the packaging bag, It is comprised so that a horizontal seal may be given to a corresponding place.

After passing, it is constituted by an interlocking member 14A composed of a timing belt, a chain, or the like having a structure that is inverted up and down and passed over the upper and lower fixed pulleys 7C and 7D.
　かかる構成の横シール上下機構１４によれば、駆動モータ７Ｍが一方の定滑車７Ｃを図２に於いて図面上反時計回転方向に回転すると、タイミングベルト又はチェーン等から成る連動部材１４Ａと各滑車７Ａ～７Ｄの噛合作用によって横シール装置７を下方に移動し、反対に定歯車７Ｃを時計回転方向に回転した場合は、横シール装置７を上方に移動できる仕組に成っていて、この駆動モータ７Ｍの回転を制御することにより、横シーラ７Ｘ，７Ｙの上下の移動量や移動位置を１パック分の長さ寸法（図４のＬ参照）に合致するように調整することができると共に、包材送り出し装置１２の送り出し速度、延いては縦シール装置６の包装フィルムＦ４の送り速度（搬送速度）に見合うように、横シーラ７Ｘ，７Ｙの上下の移動速度を制御することができるように構成されている。 According to the horizontal seal up-and-down mechanism 14 having such a configuration, when the drive motor 7M rotates one of the fixed pulleys 7C in the counterclockwise direction in FIG. 2, the interlocking member 14A made up of a timing belt or a chain and each pulley.

By controlling the rotation of 7M, the vertical movement amount and movement position of the horizontal sealers 7X and 7Y can be adjusted to match the length of one pack (see L in FIG. 4). The vertical moving speed of the horizontal sealers 7X and 7Y is controlled so as to match the feeding speed of the material feeding apparatus 12 and, consequently, the feeding speed (conveyance speed) of the packaging film F4 of the vertical sealing apparatus 6. And it is configured to be able.
　ここで、符号８で全体的に示したのは、上記横シール装置７の下側に設けたカッタ装置であって、このカッタ装置８は上記の横シール装置７が行った横シールの中央線部分を上下に切断するカッタ８Ａ，８Ｂを備えて構成されている。 Here, the reference numeral 8 generally indicates a cutter device provided on the lower side of the horizontal seal device 7, which is the center line of the horizontal seal performed by the horizontal seal device 7. Cutters 8A and 8B for cutting the portion up and down are provided.
　図４は、上述した構成の多列式自動包装機によって包装されるステイック状の包装製品Ｆ７の外観を示したものであって、図中Ｐは縦シール部、Ｌは包装製品Ｆ７の長さ寸法（サイズ）を示したものであって、本実施の形態においては、この長さ寸法Ｌ及び充填量の異なる各種サイズのステイック状包装製品Ｆ７をシール成形することができる。 FIG. 4 shows the appearance of a stick-shaped package product F7 packaged by the multi-row automatic packaging machine having the above-described configuration, where P is a vertical seal portion and L is the length of the package product F7.

Therefore, when performing vertical sealing as in the prior art, the vertical sealer is approached from the direction orthogonal to the conveyance surface of the packaging film and brought into contact with the packaging film to perform vertical sealing, and then from the packaging film. A complicated advance / retreat mechanism (reciprocating mechanism) such as retraction is unnecessary, and simplification of the configuration can be promoted, and vibration and noise can be reduced, and the conveyance speed of the packaging film can be increased.
　すなわち、本実施の形態に係る多列式自動包装機によれば、簡単かつ低コストな構成でありながら、包装フィルムを一時停止することなく所定速度で連続的に送りながら、ステイック状包装製品を多列式に自動包装することができる多列式自動包装機を提供することができる。 That is, according to the multi-row automatic wrapping machine according to the present embodiment, the stick-like packaged product is continuously fed at a predetermined speed without temporarily stopping the wrapping film while having a simple and low-cost configuration. It is possible to provide a multi-row automatic packaging machine capable of automatic packaging in a multi-row manner.
