Description
この発明は、液状被包装物の充填包装方法および該方法を利用した充填包装機に関し、とくには液状被包装物の横シール部内への噛み込みを阻止することのできる充填包装方法および充填包装機に関する。
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling and packaging method for a liquid package and a filling and packaging machine using the method, and more particularly, a filling and packaging method and a filling and packaging machine capable of preventing biting of a liquid package into a lateral seal portion. About.
近年、軟質の包装用フィルムによって飲食物、調味液、医薬品、化粧品等の液状物、粘稠物もしくは粉、粒状物、その他の被包装物を自動充填包装することが広く一般に行われている。
In recent years, automatic filling and packaging of liquid products such as foods and drinks, seasoning liquids, pharmaceuticals, and cosmetics, viscous materials or powders, granular materials, and other objects to be packaged has been widely performed.
このような被包装物の自動充填包装機は、例えば、特許文献１に記載されているように、一軸もしくは二軸延伸ベースフィルム層と無延伸のシーラント層との積層構造からなる包装用フィルム、またはベースフィルム層に感熱接着層をパートコートした単層構造になる包装用フィルムを、シーラント層あるいは感熱接着層が内側になるように中央部で折り返し、その折り返しフィルムの側縁部分を重ね合わせ、一対の縦シールロールによって加熱および加圧することにより互いに溶着させながら下方へ送り、長手方向に延在する縦シール部を形成することで、その包装用フィルムを筒状に成形する。
Such an automatic filling and packaging machine for an article to be packaged is, for example, a packaging film having a laminated structure of a uniaxial or biaxially stretched base film layer and an unstretched sealant layer, as described in Patent Document 1, Or, a packaging film that has a single-layer structure in which a heat-sensitive adhesive layer is part-coated on the base film layer is folded at the center so that the sealant layer or the heat-sensitive adhesive layer is on the inside, and the side edges of the folded film are overlapped, The packaging film is formed into a cylindrical shape by forming the vertical seal portion extending in the longitudinal direction while being welded to each other by heating and pressurizing with a pair of vertical seal rolls.
次いで、この筒状に成形されたフィルムを、横シール装置の、一対の横シールロールのそれぞれの周囲に周方向に等間隔に位置する複数本のヒートシールバーで順次に加熱および加圧することにより互いに溶着させながら下方へ送り、筒状の包装用フィルムにその幅方向に延在する横シール部を包装用フィルムの長手方向に間隔を空けて間欠的に形成することで包装袋を製袋する。このとき、包装用フィルム内に被包装物を連続的に、または筒状の包装用フィルムへの１つの横シール部の形成からその次の横シール部の形成までの間に間欠的に供給することで被包装物を各包装袋内に充填し、連続的に製造される包装袋の横シール箇所の中間部を切断機構により切断して、単包または複数包が連続する連包状態で搬出する。
Next, the cylindrically formed film is heated and pressurized sequentially by a plurality of heat seal bars positioned at equal intervals in the circumferential direction around each of the pair of horizontal seal rolls of the horizontal seal device. The packaging bags are made by feeding them downward while being welded to each other and forming intermittently spaced transverse portions in the longitudinal direction of the packaging film in the width direction of the cylindrical packaging film. . At this time, an article to be packaged is continuously supplied into the packaging film or intermittently from the formation of one horizontal seal portion to the next horizontal seal portion on the cylindrical packaging film. In this way, each package bag is filled with an item to be packaged, and the intermediate portion of the lateral seal portion of the continuously manufactured packaging bag is cut by a cutting mechanism, and the package is carried out in a continuous package of single or multiple packages. To do.
このような従来の充填包装機では、上記したように一対の横シールロールによって横シール部を形成する際に、包装用フィルムの折返し辺部分は、一の横シール部を形成した後、次の横シール部を形成するまでの間にスプリングバックによって膨らんだ状態となり、充填した液状被包装物が、毛細管作用によって折返し辺側を伝って上に吸い上げられて、次の横シール部内に噛み込まれ、シール不良を生じるおそれがあった。
In such a conventional filling and packaging machine, when the lateral seal portion is formed by the pair of lateral seal rolls as described above, the folded side portion of the packaging film forms the one horizontal seal portion, and then the next Before the horizontal seal part is formed, it is swelled by the spring back, and the filled liquid package is sucked up along the folded side by capillary action and is bitten in the next horizontal seal part. There was a risk of poor sealing.
また、横シール部を形成する際、横シールロールのヒートシールバーによって筒状の包装用フィルム内にある被包装物を押し出しながら横シールを施すことで、被包装物の横シール部内への噛み込みを抑制しているが、十分ではなく、とくに被包装物が、例えば、ドレッシングのように粒状物等を含むものである場合には、該粒状物等をヒートシールバーで押し出すことができず、横シール部内に噛み込まれてしまうおそれがある。このように横シール部内へ粒状物等が噛み込まれてしまうと、美観を損なうばかりでなく、発泡が発生してシール不良が生じ、被包装物が漏れ出すおそれもある。
In addition, when forming the horizontal seal portion, the lateral seal is applied while extruding the package in the cylindrical packaging film with the heat seal bar of the horizontal seal roll, so that the bite into the horizontal seal portion of the package is applied. However, it is not sufficient, and in particular, if the package includes a granular material such as a dressing, the granular material cannot be extruded with a heat seal bar. There is a risk of being caught in the seal portion. If particulate matter or the like is caught in the lateral seal portion in this way, not only the appearance is impaired, but also foaming occurs to cause a seal failure, and the packaged article may leak out.
したがって、とくに粒状物等を含む被包装物を充填包装する場合には、前記したように筒状の包装用フィルムへの１の横シール部の形成から、その次の横シール部の形成までの間に、間欠的に被包装物を充填することで、横シール部内への粒状物等の噛み込みを防止しているが、この方法では、被包装物を連続充填する場合に比べて生産性が極端に低下してしまうという問題点があった。
Therefore, in the case of filling and packaging a packaged article including a granular material in particular, from the formation of one horizontal seal part to the cylindrical packaging film as described above, from the formation of the next horizontal seal part. In the meantime, the packing material is intermittently filled to prevent the biting of the granular material into the horizontal seal portion. However, this method is more productive than the case where the packing material is continuously filled. There was a problem that would be extremely reduced.
そこで、本発明では、液状被包装物中に含まれる気泡や粒状物等が横シール部内に噛み込まれることなく、液状被包装物を充填することができ、生産性を向上させることのできる液状被包装物の充填包装方法およびその方法を利用した充填包装機を提供することを目的とする。
Therefore, in the present invention, the liquid package can be filled without bubbles or particles contained in the liquid package being bitten into the horizontal seal portion, and the productivity can be improved. It is an object of the present invention to provide a filling and packaging method for an article to be packaged and a filling and packaging machine using the method.

この発明の液状被包装物の充填包装方法およびその方法を利用した充填包装機では、横シールロールの周面に設けられた複数本のヒートシールバー間に、少なくとも包装用フィルムの折返し辺に相当する部分を押さえつける押え手段を設けたことにより、該押え手段によって、一の横シール部から次の横シール部の形成までの間の、包装用フィルムの折返し辺部分が、スプリングバックによって膨らむのを防止することができるため、充填された液状被包装物が該折返し辺部分を伝って次の横シール部内に吸い上げられるのを有効に阻止することができる。
In the filling and packaging method of the liquid package according to the present invention and the filling and packaging machine using the method, at least the folding side of the packaging film is provided between the plurality of heat seal bars provided on the peripheral surface of the transverse seal roll. By providing the pressing means for pressing the portion to be pressed, the folded-back side portion of the packaging film from the one horizontal seal portion to the next horizontal seal portion is swelled by the spring back. Since it can prevent, it can prevent effectively that the filled liquid to-be-packaged object is sucked up in the next horizontal seal part along this folding | turning edge part.
また、本発明では、包装用フィルムを二つ折りにした後、側縁部分に縦シール部を形成して筒状とし、その筒状の包装用フィルム（以下、「筒状フィルム」と言う。）内に液状の被包装物を充填包装するに際し、前記筒状フィルムを、両側面から絞り手段によって間欠的に挟み込んで（絞り込んで）、充填ノズルから供給された液状被包装物の筒状フィルム内での進行を一時的に阻止する。これにより、前記絞り手段の下側には、液状被包装物が介在しない部分が間欠的に形成されることになり、該部分に、一対の横シールロールによって横シール部を形成することで、横シール部内への液状被包装物、とくには液状被包装物に含まれる粒状物等の噛み込みを有効に阻止することができる。したがって、たとえ液状被包装物に粒状物等が含まれていたとしても、該粒状物等が横シール部に噛み込まれることがなく、液状被包装物を液中シール充填によって連続的に充填包装することができるため、生産性を向上させることができる。
In the present invention, after the packaging film is folded in two, a vertical seal portion is formed on the side edge portion to form a tubular shape, and the tubular packaging film (hereinafter referred to as “tubular film”). When filling and packaging a liquid package in the inside, the tubular film is intermittently sandwiched (squeezed out) from both sides by a squeezing means, and inside the cylindrical film of the liquid package to be supplied from the filling nozzle Temporarily prevent progress in Thereby, on the lower side of the squeezing means, a portion where the liquid package is not interposed is intermittently formed, and in this portion, a lateral seal portion is formed by a pair of lateral seal rolls, It is possible to effectively prevent the liquid packaging material, particularly the granular material contained in the liquid packaging material, from entering the horizontal seal portion. Therefore, even if the liquid package includes particulates, the granular material does not get caught in the horizontal seal portion, and the liquid package is continuously filled and packed by submerged seal filling. Therefore, productivity can be improved.
また、前記絞り手段は、一対の絞り板からなることが好ましく、その一対の絞り板の少なくとも一方の先端部にガス吹き出し口を設け、該ガス吹き出し口から吹き出されたガスの圧力によって筒状フィルムを振動させ、該筒状フィルム内に介在する液状物および粒状物等をしごき出すことで、横シール部内への液状被包装物の噛み込みを、さらに効果的に抑制することができる。さらに、ガスの圧力を利用することで、絞り板によって直接、筒状フィルムを挟み込んでしごく動作を補助することができ、すべり性が高まって筒状フィルムが傷つくようなおそれもない。
The throttle means is preferably composed of a pair of diaphragm plates, and a gas film is provided at the tip of at least one of the pair of diaphragm plates, and the tubular film is formed by the pressure of the gas blown from the gas nozzle. Is oscillated to squeeze out liquid substances, granular substances, and the like intervening in the tubular film, and thereby the biting of the liquid package into the horizontal seal portion can be further effectively suppressed. Furthermore, by utilizing the pressure of the gas, the tubular film can be directly sandwiched by the diaphragm plate to assist the squeezing operation, and there is no possibility that the tubular film is damaged due to an increase in slipperiness.
また、前記押え手段が、前記筒状の包装用フィルムの折返し辺部分をその全長にわたって押さえる押え板からなる場合には、該折返し辺部分への液状被包装物の進入が完全に阻止されるため、該折返し辺部分を伝って横シール部内に液状被包装物が吸い上げられる可能性がなく、一方、押え手段が、筒状の包装用フィルムを全幅にわたって押さえる押えバーからなる場合には、前記折返し辺部分のみならず、包装用フィルム全幅にわたって充填された液状被包装物の、該包装用フィルム内壁面に沿った吸い上げが抑制されるため、横シール部内への液状被包装物の噛み込みを有効に阻止することができる。さらに、押え手段として上記した押え板と押えバーの両方を設けた場合には、横シール部内への噛み込み抑制効果を一層効果的に発揮することができる。
Further, in the case where the holding means is formed of a holding plate that holds the folded side portion of the tubular packaging film over its entire length, entry of the liquid article to the folded side portion is completely prevented. In the case where there is no possibility that the liquid package is sucked up into the lateral seal portion along the folded side portion, while the holding means is composed of a holding bar that holds the tubular packaging film over its entire width, The liquid package filled over the entire width of the packaging film as well as the side portions is prevented from being sucked up along the inner wall surface of the packaging film. Can be prevented. Furthermore, when both the above-described presser plate and the presser bar are provided as the presser means, the effect of suppressing biting into the lateral seal portion can be more effectively exhibited.
また、本発明は、前記一対の絞り板を、包装用フィルムの品種や充填条件に基づいて相互に近接または離間する位置に変位可能としたこと、また押え板を筒状フィルムのフィルム幅によって位置調整できるようにしたことにより、包装用フィルムの厚みや、液状被包装物の種類、包装体の容量等に係わらず、種々の包装体の製造に有効に利用することができる。
In the present invention, the pair of diaphragms can be displaced to positions close to or away from each other based on the type of packaging film and filling conditions, and the presser plate is positioned according to the film width of the tubular film. By being able to adjust, regardless of the thickness of the packaging film, the type of the liquid package, the capacity of the package, etc., it can be effectively used for the production of various packages.
また、前記押え板による横シールロールの軸線方向の押さえ幅を、筒状フィルム幅の１～５０％としたこと、また前記押えバーを横シールロールのヒートシールバーに隣接して設けたことにより、液状被包装物の包装用フィルム内への充填が邪魔されることなく、かつ包装袋の内容積が過度に減少することなく、充填した液状被包装物の毛細管作用による吸い上げが抑制され、横シール部内への液状被包装物の噛み込みを確実に阻止することができる。
Further, the holding width in the axial direction of the horizontal seal roll by the press plate is set to 1 to 50% of the tubular film width, and the press bar is provided adjacent to the heat seal bar of the horizontal seal roll. Thus, the filling of the liquid packaging material into the packaging film is not obstructed, and the internal volume of the packaging bag is not excessively reduced. It is possible to reliably prevent the liquid package from biting into the seal portion.

In addition, as the pressing means 17, the pressing plates 18a and 18b and the pressing bars 19a and 19b may be provided together. In this case, the liquid package to be filled in the tubular film 15 is provided with the folded sides 6a and Suctioning along the inner wall surface of the tubular film 15 can be more effectively prevented, and the liquid package can be effectively suppressed from being bitten into the next horizontal seal portion 14. it can.
さらに、この充填包装機では、図２に示すように、筒状フィルム１５の走行方向で、第１の横シール部形成部４ａの、一対の横シールロール１２による横シール部１４の形成位置の手前に、絞り手段１６を設けることが好ましい。なお、絞り手段１６は、図２に示す一対の絞り板１６ａ、１６ｂを用いることが好ましいが、その他、一対の絞りロール等、走行する筒状フィルム１５を両側面から絞り込むことができればどのような機構であってもよい。
Further, in this filling and packaging machine, as shown in FIG. 2, in the traveling direction of the tubular film 15, the formation position of the lateral seal portion 14 by the pair of lateral seal rolls 12 of the first lateral seal portion forming portion 4 a is determined. It is preferable to provide the throttle means 16 in front. The diaphragm means 16 preferably uses a pair of diaphragm plates 16a and 16b shown in FIG. 2, but any other means can be used as long as the traveling cylindrical film 15 such as a pair of diaphragm rolls can be narrowed from both sides. It may be a mechanism.
この絞り手段１６としての一対の絞り板１６ａ、１６ｂは、筒状フィルム１５の側面を挟むように配置され、該絞り板１６ａ、１６ｂが、筒状フィルム１５の両側面を所要のタイミングで間欠的に挟み込む（絞り込む）ことで、充填される液状被包装物の筒状フィルム１５内での降下を一時的に阻止するように機能する。
なお、絞り手段１６は、液状被包装物中に含まれる空気をしごき出す機能および包装袋の形状と被包装物の充填量を安定化させる働きをも有している。 The pair of diaphragm plates 16a and 16b as the diaphragm means 16 are arranged so as to sandwich the side surface of the cylindrical film 15, and the diaphragm plates 16a and 16b intermittently pass through both sides of the cylindrical film 15 at a required timing.

この絞り手段１６の上記機能によって、筒状フィルム１５内には、絞り手段１６の下側に、液状物および粒状物等の降下が阻まれて、それらが介在しない部分が間欠的に形成されることになり、この部分に後段の横シールロール１２によって横シール部１４を形成することで、該横シール部１４内への液状物および粒状物等の噛み込みを有効に阻止することができる。したがって、絞り手段１６によれば、液状被包装物を横シール部１４内への噛み込みを阻止しながら連続充填包装することもできるようになる。
Due to the above function of the squeezing means 16, the liquid film and the granular material are prevented from descending in the tubular film 15 below the squeezing means 16, and portions where they are not interposed are intermittently formed. Thus, by forming the horizontal seal portion 14 at this portion by the horizontal seal roll 12 at the subsequent stage, it is possible to effectively prevent the liquid material and the granular material from being caught in the horizontal seal portion 14. Therefore, according to the squeezing means 16, the liquid package can be continuously filled and packaged while preventing biting into the lateral seal portion 14.
