Description
Siegel station zur Erzeugung von Siegelnähten an gefüllten SchiauchbeutelverpackungenSealing station for producing sealing seams on filled hose bag packaging
Die Neuerung betrifft eine Siegelstation zur Erzeugung von Siegelnähten an gefüllten Schiauchbeutelverpackungen mit einem Siegelbackenpaar und zwei einander gegenüberliegenden Siegelbacken, von denen einer beheizt ist.The innovation concerns a sealing station for producing sealing seams on filled tube bag packaging with a pair of sealing jaws and two opposing sealing jaws, one of which is heated.
Derartige Siegelstationen sind üblich. Die Siegelfläche des unteren, beheizten Siegelbackens ist dabei häufig geriffelt und die gegenüberliegende (kalte) Siegelfläche des oberen Siegelbackens weist beim Stand der Technik ebenfalls eine gleichartige Riffelung auf. Durch die Riffelungen soll die Dichtheit der Siegelnaht verbessert werden.Such sealing stations are common. The sealing surface of the lower, heated sealing jaw is often ribbed and the opposite (cold) sealing surface of the upper sealing jaw also has a similar ribbed pattern in the current state of the art. The ribbed pattern is intended to improve the tightness of the sealing seam.
Beim Stand der Technik bestehen beide Siegelbacken aus einem harten, unnachgiebigen Material (Metall). Dies bringt aber Justierprobleme mit sich, weil es schwierig ist, beide Siegelflächen, auch über eine längere Betriebszeit, genau parallel zueinander auszurichten. Sind die Siegelflächen dagegen zueinander verkantet, so leidet darunter die Qualität der angebrachten Siegel nähte.In the current state of the art, both sealing jaws are made of a hard, rigid material (metal). However, this causes adjustment problems because it is difficult to align both sealing surfaces exactly parallel to each other, even over a longer period of operation. If, on the other hand, the sealing surfaces are tilted relative to each other, the quality of the sealing seams suffers.
Der Neuerung liegt daher die Aufgabe zugrunde, eine Siegel Station mit den eingangs genannten Merkmalen so auszugestalten, daß die Justierprobleme weitestgehend vermieden werden, ohne daß darunter die Qualität der in der Siegel station hergestellten Siegelnähte leidet.The innovation is therefore based on the task of designing a sealing station with the features mentioned above in such a way that the adjustment problems are avoided as far as possible without the quality of the sealing seams produced in the sealing station suffering as a result.
Zur Lösung dieser Aufgabe ist die Neuerung dadurch gekennzeichnet, daß die Siegelfläche des unbeheizten Siegelbackens durch wenigstens einen Siegel streifen aus elastomerem Material ausgebildet ist.To solve this problem, the innovation is characterized in that the sealing surface of the unheated sealing jaw is formed by at least one sealing strip made of elastomeric material.
Mit der gegebenen technischen Lehre nach der vorliegenden Neuerung wirdWith the given technical teaching according to the present innovation,
also der wesentliche Vorteil erreicht, daß nun die (obere) Siegelfläche des Siegelbackens elastisch verformbar ausgebildet ist und hierdurch evtl. Justierungenauigkeiten des oberen oder des unteren Siegelbackens keine Rolle mehr spielen. Kommt es zu einer e'itsprechenden Unparallelität zwischen dem oberen und dem unteren Siegelbacken, dann gleichen die elastomer verformbaren Siegelstreifen diese Un^enauigkeiten aus. D.h. die obere, kalte Siegelflä'che wird mit relativ gleichbleibender Kraft gegen die untere beheizte Siegelfläche des unteren Siegelbalkens gepresst, wodurch dadurch eine Siegelet größtmöglicher Dichtheit im Bereich des Schlauchbeutels angebracht wird.The main advantage is that the (upper) sealing surface of the sealing jaw is now elastically deformable and any adjustment inaccuracies of the upper or lower sealing jaw are no longer important. If there is a corresponding non-parallelism between the upper and lower sealing jaws, the elastomerically deformable sealing strips compensate for these inaccuracies. This means that the upper, cold sealing surface is pressed with a relatively constant force against the lower, heated sealing surface of the lower sealing bar, thereby creating a seal with the greatest possible tightness in the area of the tubular bag.
Wichtig hierbei ist, daß die elastomer verformbaren Siegelstreifen im oberen Siegelbacken hitzebeständig sind bis zu einer Temperatur von etwa 2000C. Als Material für derartige Siegelstreifen wird etwa e™ Material aus Silikon oder einer Silikonmischung bevorzugt.It is important that the elastomeric sealing strips in the upper sealing jaw are heat-resistant up to a temperature of about 200 ° C. The preferred material for such sealing strips is e™ material made of silicone or a silicone mixture.
Ebenso sind selbstverständlich auch andere elastomer verformbare und bis zu diesem Temperaturgrenzwert unempfindliche Siegel streifen verwendbar.Of course, other elastomeric sealing strips that are deformable and insensitive up to this temperature limit can also be used.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, daß jeder Siegelfläche des unteren Siegelbalkens ein einziger Siegel streifen in der oberen Siegel fläche des oberen Siegelbalkens zugeordnet ist.In a preferred embodiment of the present invention, it is provided that each sealing surface of the lower sealing bar is assigned a single sealing strip in the upper sealing surface of the upper sealing bar.
Hierbei wird es bevorzugt, wenn jeder Siegel streifen im Querschnitt konisch ausgebildet ist und eine abgerundete Spitze aufweist? It is preferred if each sealing strip is conical in cross-section and has a rounded tip .
Die einen Radius aufweisende Spitze drückt sich beim Siegelvorgang auf das sich verflüssigende Kunststoffmaterial der Schlauchfolie &ugr;&eegr;(* verdrängt dieses Kunststoffmaterial teilweise nach außen, so daß sich die Siegelfläche vergrößert. Beim Öffnen der Siegelstation werden die beiden Siegelbacken auseinandergefahren, wobei die elastomer'en Siegel streifen langsam außer Eingriff mit der angebrachten §iegelnaht kommen und hierdurch ein Klebeeffekt vermieden wird.During the sealing process, the tip, which has a radius, presses itself onto the liquefying plastic material of the tubular film &ugr;&eegr;( * partially displaces this plastic material outwards, so that the sealing surface is enlarged. When the sealing station is opened, the two sealing jaws are moved apart, whereby the elastomer sealing strips slowly come out of engagement with the attached sealing seam, thus preventing an adhesive effect.
Ferner ist wesentlicher Vorteil, daß während des Siegeins sich die Siegel streifen rund verformen und hierdurch das Material nach außen verdrängen und hierbei die Siegelnaht verbreitern und im übrigen eine Materialanhäufung im Bereich der Schlauchbeutel schräge der Schlauchbeutelverpackung anbringen. Es handelt sich hierbei um eine Materialanhäufung, die gerade in der kritischen Zone der Schlauchbeutelverpackung angebracht wird, wodurch es verhindert wird, daß die Schlauchbeutel schrägen sich voneinander trennen und aufreissen.Another significant advantage is that during sealing the sealing strips become rounded and thereby push the material outwards, widening the sealing seam and also creating a material accumulation in the area of the tubular bag slant of the tubular bag packaging. This is a material accumulation that is created precisely in the critical zone of the tubular bag packaging, which prevents the tubular bag slant from separating from one another and tearing open.
Die Verwendung der neuerungsgemässen Siegel streifen hat also den Vorteil, daß damit auch die Haltbarkeit der Verbindung im Bereich der Schlauchbeutel schräge wesentlich verbessert wird.The use of the new sealing strips has the advantage that the durability of the connection in the area of the bag bevel is significantly improved.
Im übrigen ergibt sich der weitere Vorteil, daß mit der Verwendung von elastomer verformbaren Siegelstreifen sich nach erfolgter Siegelung die vorher rund verformte Spitze des Siegelstreifens nun wieder konisch zurückverformt in die ursprüngliche Lage und hierdurch der Klebeeffekt an der Folie der Schlauchbeutelverpackung vermieden wird, und gleichzeitig wird damit gewährleistet, daß die Siegelnaht beim Öffnen nicht wieder aufreisst.Furthermore, the use of elastomer-deformable sealing strips has the further advantage that, after sealing, the previously rounded tip of the sealing strip now conically deforms back into its original position, thereby avoiding the sticking effect on the film of the tubular bag packaging and at the same time ensuring that the sealing seam does not tear again when opened.
Die Neuerung wird nun anhand eines Ausführungsbeispiels näher dargestellt.The innovation will now be explained in more detail using an example implementation.

Figur 2 zeigt einen Siegelstreifen nach der Neuerung in Seitenansicht.Figure 2 shows a sealing strip after the innovation in side view.
Figur 3 zeigt den Siegel streifen in Vorderansicht. Figur 4 zeigt schematisiert die Verhältnisse beim Siegeln in übertriebener Darstellung.Figure 3 shows the sealing strip from the front. Figure 4 shows the sealing conditions in an exaggerated representation.
Gemäss der Figur 1 besteht die Siegelstation aus einem oberen, unbeheizten Siegelbacken 1 und aus einem unteren, über einen Heizkörper 13 beheizten Siegelbacken 2.According to Figure 1, the sealing station consists of an upper, unheated sealing jaw 1 and a lower sealing jaw 2 heated by a heating element 13.
Der untere Siegelbacken 2 weist einen Spalt 14 auf, der an beiden Seiten jeweils eine Siegelfläche 12 definiert.The lower sealing jaw 2 has a gap 14 which defines a sealing surface 12 on both sides.
Der obere Siegelbacken 1 weist einen zentralen, sich über die Längsachse des Siegelbalkens erstreckenden, Schlitz 8 auf, in dem ein Messer 9 verschiebbar und absenkbar geführt ist.The upper sealing jaw 1 has a central slot 8 extending over the longitudinal axis of the sealing bar, in which a knife 9 is guided so as to be displaceable and lowerable.
Die Siegelflächen des oberen Siegelbackens 1 werden hierbei durch zwei einen parallelen Abstand zueinander einnehmende Siegelstreifen 11 gebildet, wobei jeder Siegelstreifen 11 in einer Ausnehmung 10 im Siegelbacken 1 lösbar gehalten ist.The sealing surfaces of the upper sealing jaw 1 are formed by two sealing strips 11 that are spaced parallel to one another, with each sealing strip 11 being releasably held in a recess 10 in the sealing jaw 1.
Der Siegelstreifen 11 besteht bevorzugt aus einem Silikonmaterial und weist eine abgerundete, konisch zulaufende Spitze 15 auf (vergl. Figur 2,3).The sealing strip 11 preferably consists of a silicone material and has a rounded, conical tip 15 (see Figures 2, 3).
Die Figur 1 zeigt die Verhältnisse beim Siegeln einer Schlauchbeutel verpackung, wobei erkennbar ist, daß die Schlauchbeutel 5 zusammenhängen und in Pfeilrichtung 6 durch die Siegelstation 1,2 transportiert werden.Figure 1 shows the conditions when sealing a tubular bag packaging, whereby it can be seen that the tubular bags 5 are connected and are transported in the direction of arrow 6 through the sealing station 1,2.
Im Schlauchbeutel 5 ist hierbei ein gestapeltes Packungsgut 7 vorhanden.A stacked packaged goods 7 is present in the tubular bag 5.
Die Schlauchbeutel 5 bilden hierbei Schrägen 4 im Bereich der Siegelnähte, wobei die Siegelbacken 1,2 zugeordnete Schrägen 3 aufweisen, um in diesem Bereich keine Verletzung der Schlauchbeutelschräge 4 zu vollziehen.The tubular bags 5 form bevels 4 in the area of the sealing seams, whereby the sealing jaws 1, 2 have associated bevels 3 in order to avoid damaging the tubular bag bevel 4 in this area.
In der gezeichneten Stellung bringen also die Siegelflächen 12 des unteren Siegelbackens 2 die entsprechenden Siegel nähte an, wobei inIn the position shown, the sealing surfaces 12 of the lower sealing jaw 2 create the corresponding sealing seams, whereby
Gegenüberstellung die Siegelstreifen 11 des oberen Siegelbackens 1 den Siegelflächen 12 gegenüberliegen.Comparison of the sealing strips 11 of the upper sealing jaw 1 and the sealing surfaces 12.
Gemäss Figur 4 ist erkennbar, daß die während des Siegel Vorgangs sich rund verformenden Spitzen der Siegelstreifen 11 eine Material anhäufung 16 in den spitz zusammenlaufenden Schiauchbeutelschrägen 4 ausführen. Damit werden die Schlauchbeutel schrägen 4 stabilisiert und verfestigt. Eine weitere Materialanhäufung 17 erfolgt im Außenbereich jeder Siegelnaht 18, wodurch die Siegelnaht 18 durch diesen Verdrängungseffekt auch in ihrem Aussenbereich durch die Materialanhäufung 17 stabilisiert und verfestigt wird. Auf diese Weise wird durch die Verwendung von elastomeren Siegelstreifen eine wesentliche Verfestigung der Siegelnaht 18 und damit eine absolute Dichtheit erreicht.According to Figure 4, it can be seen that the tips of the sealing strips 11, which become round during the sealing process, create a material accumulation 16 in the tubular bag slopes 4 that converge to a point. This stabilizes and strengthens the tubular bag slopes 4. A further material accumulation 17 occurs in the outer area of each sealing seam 18, whereby the sealing seam 18 is also stabilized and strengthened in its outer area by the material accumulation 17 due to this displacement effect. In this way, the use of elastomeric sealing strips results in a significant strengthening of the sealing seam 18 and thus absolute tightness.
Bei höher beanspruchten Siegelnähten ist es vorgesehen, statt jeweils einem Siegelstreifen 12, der einer Siegelnaht 18 zugeordnet ist, zwei nebeneinanderliegende Siegel streifen zu verwenden.For sealing seams subject to higher stresses, it is intended to use two sealing strips lying next to one another instead of one sealing strip 12 assigned to one sealing seam 18.
