Description

本発明は、三方シールフイルム包装機に係り、特に、上下一対の横シーラにおける接近・離反の垂直方向の駆動と水平方向の往復移動とを行なう機構を簡素化し、その製造を容易にする三方シールフイルム包装機に関する。   The present invention relates to a three-side seal film packaging machine, and more particularly, a three-side seal that simplifies a mechanism for performing vertical driving and reciprocating movement in a horizontal direction in a pair of upper and lower horizontal sealers and facilitates the manufacture thereof. The present invention relates to a film packaging machine.

従来から、包装フイルムに被包装物を被包して縦シーラの溶着および横シーラ（エンドシーラ）の溶着溶断により被包装物の縦方向寸法に応じた所定長の三方シール包袋を形成するにあたり、カム、トグル機構、レバー、クランクを用いて包装フイルムの搬送速度に同期して互いに接近・離反する垂直方向の駆動と、水平方向の往復移動とを行なうように上下一対の横シーラを駆動するフイルム包装機が知られている（例えば、特許文献１）。   Conventionally, a packaging film is encapsulated in a package, and a three-side sealed wrapping bag of a predetermined length according to the longitudinal dimension of the packaged object is formed by welding a vertical sealer and a transverse sealer (end sealer). Using a cam, toggle mechanism, lever, and crank, a pair of upper and lower horizontal sealers are driven so as to drive in the vertical direction to approach and separate from each other in synchronism with the conveyance speed of the packaging film and to reciprocate in the horizontal direction. A film packaging machine is known (for example, Patent Document 1).

特開２００１−２７８２２２号公報（図１、図３、図６）Japanese Unexamined Patent Publication No. 2001-278222 (FIGS. 1, 3, and 6)

しかしながら、このようなフイルム包装機では、カム、トグル機構、レバー、クランクを使用して上下一対の横シーラを接近・離反させる垂直方向の駆動と、水平方向の往復移動とを行なっているので機構が極めて複雑となり、その製造が面倒でコストが嵩み、騒音が発生し、また保守が煩瑣になるという難点があった。   However, such a film packaging machine uses a cam, a toggle mechanism, a lever, and a crank to drive a vertical drive for moving a pair of horizontal sealers up and down and a horizontal reciprocating movement. However, the manufacturing process is cumbersome and costly, noise is generated, and maintenance is troublesome.

本発明は、このような難点を解決するためになされたもので、上下一対の横シーラにおける接近・離反の垂直方向の駆動と、水平方向の往復移動とを行なう機構が簡素であって、製造や保守が容易で、騒音が発生せず、而も製造コストが低廉な三方シールフイルム包装機を提供することを目的とする。   The present invention has been made to solve such a problem, and has a simple mechanism for performing vertical drive for approaching / separating in a pair of upper and lower horizontal sealers and reciprocation in the horizontal direction, and is manufactured. Another object of the present invention is to provide a three-side seal film packaging machine that is easy to maintain, does not generate noise, and is inexpensive to manufacture.

このような目的を達成するため本発明の三方シールフイルム包装機は、被包装物をフォーマにより包装フイルムに被包し、縦シーラの溶着および一対の横シーラの溶着溶断により所定包袋長の三方シール包袋を形成するものである。   In order to achieve such an object, the three-side seal film packaging machine of the present invention wraps an article to be wrapped in a packaging film by a former, and welds a vertical sealer and a pair of horizontal sealers so as to have a predetermined packaging length. It forms a sealed bag.

本発明の三方シールフイルム包装機において、一対の横シーラは、それぞれ平行配置された縦ビーム、横ビーム、柱ビームで形成されたフレームに装着され、かつ定位置に植立されたリニアバーに沿って往復摺動自在に設けられ、包装フイルムの搬送速度に同期して互いに接近・離反するように一対の横シーラを上下に駆動するダブルクランク機構と、包装フイルムへの接触時点より包装フイルムからの離反時点まで包装フイルムの搬送速度に同期して一対の横シーラを移動させ、包装フイルムからの離反時点より包装フイルムへの接触時点まで包装フイルムの搬送速度から変速させて一対の横シーラを揺動するスライダクランク機構とを備えている。   In the three-side seal film wrapping machine of the present invention, the pair of horizontal sealers is mounted on a frame formed of a vertical beam, a horizontal beam, and a column beam arranged in parallel, and along a linear bar planted at a fixed position. A double-crank mechanism that is slidable back and forth and drives a pair of horizontal sealers up and down so as to approach and separate from each other in synchronization with the conveyance speed of the packaging film, and separation from the packaging film from the point of contact with the packaging film The pair of horizontal sealers are moved in synchronization with the transport speed of the packaging film up to the point in time, and the pair of horizontal sealers are swung by shifting from the transport speed of the packaging film from the time of separation from the packaging film to the time of contact with the packaging film. And a slider crank mechanism.

また、本発明の三方シールフイルム包装機において、ダブルクランク機構は、横シーラ駆動モータで駆動される駆動部と、駆動部で回動される横シーラクランクと、横シーラクランクで運動変換され一対の横シーラの下シーラを上下に駆動する下シーラ連接桿と、横シーラクランクで運動変換され一対の横シーラの上シーラを上下に駆動する上シーラ連接桿とを備えている。   In the three-side seal film packaging machine of the present invention, the double crank mechanism includes a drive unit driven by a lateral sealer drive motor, a lateral sealer crank rotated by the drive unit, and a pair of motions converted by a lateral sealer crank. A lower sealer connecting rod that drives the lower sealer of the horizontal sealer up and down, and an upper sealer connecting rod that is motion-converted by the horizontal sealer crank and drives the upper sealer of the pair of horizontal sealers up and down.

本発明の三方シールフイルム包装機において、スライダクランク機構は、横シーラ駆動モータで駆動される駆動部と、駆動部で回動される横シーラクランクと、定位置でリニアバーに固定されて揺動自在の横シーラ揺動軸が嵌合し横シーラクランクの回動によって揺動し摺動して一対の横シーラを揺動する横シーラスライダとを備えている。   In the three-side seal film packaging machine of the present invention, the slider crank mechanism includes a drive unit driven by a horizontal sealer drive motor, a horizontal sealer crank rotated by the drive unit, and is fixed to a linear bar at a fixed position and can swing. And a horizontal sealer slider that swings and slides by the rotation of the horizontal sealer crank to swing the pair of horizontal sealers.

本発明の三方シールフイルム包装機において、制御部９ａは、包装フイルム１１を搬送する供給コンベア３を駆動する供給コンベアモータＭ３と、センターコンベア６及び縦シーラ４、４’を回転駆動する縦シーラモータＭ２とを、包装フイルム１１の搬送速度に同期するように制御する第１の制御回路７０を備えている（図１、図３、図１０、図１１）。   In the three-side seal film packaging machine of the present invention, the control unit 9a includes a supply conveyor motor M3 that drives the supply conveyor 3 that conveys the packaging film 11, and a vertical sealer motor M2 that rotationally drives the center conveyor 6 and the vertical sealers 4 and 4 ′. Are controlled so as to be synchronized with the transport speed of the packaging film 11 (FIGS. 1, 3, 10, and 11).

本発明の三方シールフイルム包装機において、制御部９ａは、横シーラ駆動モータＭ１を、包装フイルム１１への接触時点Ｌａより包装フイルム１１からの離反時点Ｌｂまで包装フイルム１１の搬送速度に同期して一対の横シーラ５、５’を移動させ、包装フイルム１１からの離反時点Ｌｂより包装フイルム１１への接触時点Ｌａまで包装フイルム１１の搬送速度から変速させて一対の横シーラ５、５’を揺動するように制御する第２の制御回路７１を備えている（図１、図３、図１０、図１１）。   In the three-side seal film packaging machine of the present invention, the controller 9a synchronizes the lateral sealer drive motor M1 with the transport speed of the packaging film 11 from the contact point La to the packaging film 11 to the separation point Lb from the packaging film 11.

A second control circuit 71 for controlling the movement is provided (FIGS. 1, 3, 10, and 11).

このように構成された三方シールフイルム包装機において、オペレータ（作業者）は包装フイルム１１をフイルムテンショナー１２を介してフォーマ２から縦シーラ４、４’に予め案内し、フォーマ２により包装フイルム１１で被包装物２０を被包する三方シール包袋を準備する。なお、包装フイルム１１を縦シーラ４、４’で溶着、横シーラ５、５’で溶着溶断できるように各シーラのヒータ３６、３７（図１１）は予め通電され温度制御される。   In the three-side seal film packaging machine configured as described above, an operator (operator) guides the packaging film 11 from the former 2 to the vertical sealers 4 and 4 ′ via the film tensioner 12 in advance. A three-side sealed wrapping bag for enclosing the object to be packaged 20 is prepared. In addition, the heaters 36 and 37 (FIG. 11) of each sealer are energized in advance and temperature controlled so that the packaging film 11 can be welded by the vertical sealers 4 and 4 'and welded and cut by the horizontal sealers 5 and 5'.

オペレータ（作業者）が被包装物２０を供給コンベア３に載置し、操作パネル１３の包装開始釦（図示せず）を押下すると、供給コンベア３は、伝導・制御ボックス９の外側に取付けられた供給コンベアモータＭ３から伝導・制御ボックス９の内側に取付けられた伝導部９ｂにより駆動される。   When an operator (operator) places the article to be packaged 20 on the supply conveyor 3 and presses a packaging start button (not shown) on the operation panel 13, the supply conveyor 3 is attached to the outside of the conduction / control box 9. It is driven from the supply conveyor motor M3 by the conduction portion 9b attached to the inside of the conduction / control box 9.

同時に、伝導・制御ボックス９に設けられる制御部９ａは、供給コンベア３の送り量を包装長エンコーダ７２で検知し、その制御信号が入力される。   At the same time, the controller 9a provided in the conduction / control box 9 detects the feed amount of the supply conveyor 3 with the packaging length encoder 72, and the control signal is input.

縦シーラ４、４’は、制御部９ａの第２の制御回路７１により、伝導・制御ボックス９の外側に取付けられた縦シーラモータＭ２から伝導・制御ボックス９の内側に取付けられた伝導部９ｃにより回転駆動されてフォーマ２により三方シール包袋に形状付けされた包装フイルム１１が縦シールされる。   The vertical sealers 4, 4 ′ are transferred from the vertical sealer motor M 2 mounted outside the conduction / control box 9 by the second control circuit 71 of the control unit 9 a to the conduction unit 9 c mounted inside the conduction / control box 9. The wrapping film 11 that is driven to rotate and shaped into a three-sided sealed wrap by the former 2 is vertically sealed.

縦シールされ被包装物２０が内包された包装フイルム１１はセンターコンベア６が伝導部９ｃによって駆動され、一対の横シーラ５、５’へ送り込まれる。   The wrapping film 11 which is vertically sealed and includes the packaged object 20 is fed to the pair of horizontal sealers 5, 5 'by the center conveyor 6 being driven by the conductive portion 9c.

伝導・制御ボックス９に設けられる制御部９ａは、横シーラ５、５’の運動を検知して横シーラ原点センサ７４、横シーラ変速センサ７５から制御信号が入力される。   The control unit 9 a provided in the conduction / control box 9 detects the movement of the lateral sealers 5, 5 ′ and receives control signals from the lateral sealer origin sensor 74 and the lateral sealer speed change sensor 75.

ダブルクランク機構３５は、制御部９ａの第１の制御回路７０により、横シーラ駆動モータＭ１で駆動される横シーラ駆動歯車３３及び横シーラ従動歯車３２からなる駆動部３４で回動される横シーラクランク３０で運動変換され下シーラ連接桿５２により一対の横シーラ５、５’の下シーラ５を上下に駆動するとともに、横シーラクランク２８で運動変換され上シーラ連接桿２６により一対の横シーラの上シーラ５’を上下に駆動する。このようにして、ダブルクランク機構３５は包装フイルム１１の搬送速度に同期して互いに接近・離反するように、即ち１８０°位相がずれて一対の横シーラ５、５’を上下に駆動する（図６（ａ）、（ｂ））。   The double crank mechanism 35 is a horizontal sealer rotated by a drive unit 34 including a horizontal sealer drive gear 33 driven by a horizontal sealer drive motor M1 and a horizontal sealer driven gear 32 by a first control circuit 70 of the control unit 9a. The lower sealer connecting rod 52 moves the lower sealer 5 and the lower sealer 5 is driven up and down by the lower sealer connecting rod 52, and the lower sealer connecting rod 26 moves the pair of horizontal sealers by the upper sealer connecting rod 26. The upper sealer 5 'is driven up and down. In this way, the double crank mechanism 35 drives the pair of horizontal sealers 5 and 5 'up and down so as to approach and separate from each other in synchronism with the transport speed of the packaging film 11, that is, 180 degrees out of phase. 6 (a), (b)).

同時に、スライダクランク機構５０は、横シーラ駆動モータＭ１で駆動される横シーラ駆動歯車３３及び横シーラ従動歯車３２からなる駆動部３４で横シーラクランク３０が回動され、かつ横シーラスライダ５２ａにより定位置でリニアバー５６に固定されて揺動自在の横シーラ揺動軸５４の両端部に係止されたローラ５１が長孔５２ｂに嵌合し横シーラクランク３０の回動によって揺動し摺動して一対の横シーラ５、５’を揺動する（図４（ａ）、（ｂ））。   At the same time, in the slider crank mechanism 50, the horizontal sealer crank 30 is rotated by the drive unit 34 including the horizontal sealer drive gear 33 and the horizontal sealer driven gear 32 driven by the horizontal sealer drive motor M1, and the slider crank mechanism 50 is fixed by the horizontal sealer slider 52a. A roller 51 fixed to the linear bar 56 at a position and locked to both ends of a swingable horizontal sealer swing shaft 54 is fitted into the elongated hole 52b and swings and slides by the rotation of the horizontal sealer crank 30. Then, the pair of horizontal sealers 5, 5 ′ are swung (FIGS. 4A and 4B).

即ち、スライダクランク機構５０により、包装フイルム１１への接触時点Ｌａより包装フイルム１１からの離反時点Ｌｂまで包装フイルム１１の搬送速度に同期して一対の横シーラ５、５’を移動させ、包装フイルム１１からの離反時点Ｌｂより包装フイルム１１への接触時点Ｌａまで包装フイルム１１の搬送速度から変速させて一対の横シーラ５、５’を揺動する（図７、図８）。   That is, the slider crank mechanism 50 moves the pair of horizontal sealers 5, 5 'in synchronization with the transport speed of the packaging film 11 from the contact point La to the packaging film 11 to the separation point Lb from the packaging film 11, and the packaging film 11 is moved. The pair of horizontal sealers 5 and 5 'are oscillated by shifting from the conveying speed of the packaging film 11 from the separation time Lb from 11 to the contact time La to the packaging film 11 (FIGS. 7 and 8).

この場合、図７、図８に示すように、一対の横シーラ５、５’は被包装物２０を被包した包装フイルム１１が通過するセンターラインＣＬを挟んで上下方向にオーバーラップすることになるので、その逃げを上シーラ２１に設けたバネ２３で吸収することができる。なお、このバネ２３は一対の横シーラ５、５’の包装フイルム１１に対する溶着溶断圧力を適度に規制する機能も果たす。   In this case, as shown in FIGS. 7 and 8, the pair of horizontal sealers 5 and 5 ′ overlap in the vertical direction across the center line CL through which the packaging film 11 that encloses the package 20 passes. Therefore, the escape can be absorbed by the spring 23 provided on the upper sealer 21. The spring 23 also functions to moderately regulate the welding and fusing pressure of the pair of horizontal sealers 5 and 5 ′ on the packaging film 11.

このようにして一対の横シーラ５、５’は、１８０°位相がずれた上下動と、往復揺動とが合成されて図７に示すような合成軌跡ＵＬ、ＬＬを描く運動を行なって、一対の横シーラ５、５’の溶着溶断により、供給コンベア３の送り量が包装長エンコーダ７２で計測されて設定パネル１０によって設定されたパラメータに応じて所定包袋長の三方シール包袋２０ａを形成する。   In this way, the pair of horizontal sealers 5 and 5 ′ perform a motion of drawing a combined trajectory UL and LL as shown in FIG. By welding and cutting the pair of horizontal sealers 5 and 5 ′, the feed amount of the supply conveyor 3 is measured by the packaging length encoder 72, and the three-side sealed packaging bag 20 a having a predetermined packaging length is set according to the parameters set by the setting panel 10. Form.

こうして形成された三方シール包袋２０ａは、伝導部９ｃによって駆動される搬出コンベア７で搬出される。   The three-side seal wrapping bag 20a formed in this way is carried out by the carry-out conveyor 7 driven by the conductive portion 9c.
