Siegelbacke zur Erzeugung von Siegelnähten an gefüllten Schlauchbeutel verpackungenSealing jaw for creating sealing seams on filled tubular bag packaging

Die Neurung betrifft eine beheizbare Siegelbacke zur Erzeugung von Siegelnähten an gefüllten Schlauchbeutel verpackungen mit einem im Querschnitt im wesentlichen trapezförmigen, symmetrischen Profilen und mit einem mittigen Schlitz für ein Trennmesser.The innovation concerns a heatable sealing jaw for producing sealing seams on filled tubular bag packaging with a cross-section that is essentially trapezoidal and symmetrical and with a central slot for a separating knife.

Mit derartigen Siegelbacken werden Siegelnähte an mit Produkten gefüllten Schlauchbeutel verpackungen angebracht. Hierzu ist ein derartiges Siegelbackenpaar vorgesehen, wobei man die obere Siegelbacke gegen die untere Siegel backe führt. Zwischen den einander gegenüberliegenden Siegelbacken laufen dabei die gefüllten Schlauchbeutel verpackungen hindurch. Dabei werden die Siegelnähte an denSuch sealing jaws are used to apply sealing seams to tubular bag packaging filled with products. A pair of sealing jaws is provided for this purpose, whereby the upper sealing jaw is guided against the lower sealing jaw. The filled tubular bag packaging runs between the opposing sealing jaws. The sealing seams are then applied to the

Schlauchbeutelverpackungen angelegt und diese werden gleichzeitig getrennt, wozu ein Trennmesser in den mittigen Schlitz der Siegelbacken hin- und hergeht.Tubular bag packaging is created and these are simultaneously separated, whereby a separating knife moves back and forth in the central slot of the sealing jaws.

Bekannte derartige Siegelbacken sind im Querschnitt im wesentlichen trapezförmig ausgebildet. Sie sind verhältnismässig breit.Known sealing jaws of this type are essentially trapezoidal in cross-section. They are relatively wide.

Jede Siegelbacke weist einen mittleren, in Längsrichtung des Backens verlaufenden Schlitz auf, durch den ein Messer hindurchgreifen kann, welches nach erfolgtem Siegel Vorgang die beiden parallel nebeneinander angebrachten Siegel nähte trennt.Each sealing jaw has a central slot running lengthwise along the jaw, through which a knife can pass, which separates the two parallel seal seams after the sealing process has been completed.

Damit wird erreicht, daß eine in einer Kette durchlaufend vorhandene Schlauchbeutel verpackung jeweils bezogen auf zwei nebeneinanderliegende Schlauchbeutelverpackungen an der Vorderseite der hinten liegenden und an der Rückseite der vorne liegenden Schlauchbeutel packungen versiegelt wird.This ensures that a continuous flow pack packaging in a chain is sealed on the front of the flow packs at the back and on the back of the flow packs at the front in relation to two flow packs lying next to each other.

Das Messer dient dann - wie beschrieben - zur Abtrennung der beim Versiegeln noch zusammenhängenden Schiauchbeutelpackungen.The knife is then used - as described - to separate the tube bag packs that are still connected during sealing.

Nachteil der bisher bekannten Siegelbacken war die relativ große Backenbreite dieses Siegelbackens. Die Backenbreite wird hierbei definiert aus der Schlitzbreite, der Siegelbreite, die zusätzlich noch durch seitliche Flächen ergänzt wird, so daß dieses zusammengesetzte Maß die Backenbreite angibt.The disadvantage of the previously known sealing jaws was the relatively large jaw width of this sealing jaw. The jaw width is defined here from the slot width, the sealing width, which is additionally supplemented by side surfaces, so that this combined measurement indicates the jaw width.

Ein derartiger Siegelbacken muß mit seiner Backenbreite in den Zwischenraum zwischen zwei hintereinanderliegenden Schlauchbeutel verpackungen fahren, um dort die oben beschriebenen Siegelnähte anzubringen.Such a sealing jaw must move with its jaw width into the space between two consecutive tubular bag packages in order to apply the sealing seams described above.

Hierbei war eine bisher nicht zu unterschreitende Backenbreite vorhanden, die dazu führte, daß der Zwischenraum zwischen den noch zusammenhängenden Schlauchbeutelverpackungen relativ lang gewählt werden musste, um zu gewährleisten, daß die Siegelbacken mit ihrer relativ großen Backenbreite in den Zwischenraum zwischen diese Schlauchbeutelpackungen fahren konnten. Damit war aber der Nachteil eines relativ großen Folienverbrauchs verbunden oder wenn man den Folienverbrauch reduzieren wollte, bestand der Nachteil, daß dann die Siegelnaht unter Spannung angebracht werden musste, wodurch die Gefahr bestand, daß die Siegelnaht nicht dicht war.The jaw width was previously unacceptable, which meant that the gap between the tubular bag packages that were still connected had to be relatively long in order to ensure that the sealing jaws, with their relatively large jaw width, could move into the gap between these tubular bag packages. However, this had the disadvantage of a relatively large amount of film being used, or if you wanted to reduce the amount of film being used, there was the disadvantage that the sealing seam had to be applied under tension, which meant that there was a risk that the sealing seam would not be tight.

Der vorliegenden Neuerung liegt deshalb die Aufgabe zugrunde, einenThe present innovation is therefore based on the task of

Siegelbacken der eingangs genannten Art so auszubilden, daß dieSealing jaws of the type mentioned above are to be designed in such a way that the

Siegelnähte zuverlässig dicht gefertigt werden können und die Spannung auf die Siegelnaht verringert wird.Sealed seams can be reliably sealed and the tension on the sealed seam is reduced.

Zur Lösung dieser Aufgabe ist die Neuerung dadurch gekennzeichnet, daß sich an die zum Versiegeln dienende Siegelfläche beidseits Schrägen anschließen, die mit der Siegelfläche stumpfe Winkel einschließen und anTo solve this problem, the innovation is characterized by the fact that bevels are connected to the sealing surface on both sides, which form obtuse angles with the sealing surface and

diese wiederum gerade Abschnitte, die im wesentlichen rechtwinklig zur Siegelfläche verlaufen, die in nach außen weisende Radien übergehen, die in den Außenkanten des Siegelbackens enden.These in turn have straight sections that run essentially at right angles to the sealing surface, which merge into outward-facing radii that end in the outer edges of the sealing jaw.

Mit der gegebenen technischen Lehre nach der vorliegenden Neuerung wird also der wesentliche Vorteil erreicht, daß bei gleichbleibender Siegelbreite der Platzbedarf für die Siegelung selbst vermindert ist.With the given technical teaching according to the present innovation, the essential advantage is achieved that the space required for the seal itself is reduced while the seal width remains the same.

Damit besteht also der Vorteil, daß die Schlauchbeutelfolie nicht mehr unter hoher Spannung gesiegelt wird, sondern daß sie relativ spannungslos versiegelt wird, wodurch eine wesentlich höhere Dichtheit der Siegelnaht gewährleistet ist.This has the advantage that the tubular bag film is no longer sealed under high tension, but rather that it is sealed with relatively little tension, which ensures a much higher tightness of the sealing seam.

Aufgrund der neuerungsgemäss gegebenen Verminderung der Backenbreite werden also bei der Anbringung der Siegelnähte die Schiauchbeutelschrägen nicht mehr so stark gestrafft, weil sie nun länger ausgebildet sind.Due to the new reduction in the width of the jaws, the hose bag slopes are no longer tightened as much when the sealing seams are applied because they are now longer.

Eine bevorzugte Ausführungsform der Neuerung sieht vor, wenn auch die Schlitzbreite im Siegelbacken zum Durchführen eines Messers vermindert ist. Damit wird der wesentliche Vorteil erreicht, daß bei Anwendung eines dünneren Schlitzes und eines entsprechend angepassten Messers der Abstand zwischen den parallel nebeneinander liegenden Siegelnähten vermindert wird.A preferred embodiment of the innovation provides that the width of the slot in the sealing jaw is also reduced to allow a knife to be passed through. This achieves the significant advantage that when using a thinner slot and a correspondingly adapted knife, the distance between the parallel sealing seams is reduced.

Desweiteren wird der Abstand der parallelen Flächen 12 auf ein Minimum reduziert.Furthermore, the distance between the parallel surfaces 12 is reduced to a minimum.

Eine bevorzugte Ausführungsform der vorliegenden Neuerung wird anhand der Zeichnungen näher beschrieben.A preferred embodiment of the present innovation is described in more detail with reference to the drawings.

Hierbei ergeben sich aus den Zeichnungen und ihrer Beschreibung weitere Vorteile und Merkmale der Neuerung.The drawings and their descriptions reveal further advantages and features of the innovation.

Figur 1 zeigt schematisiert in Seitenansicht einen Siegelbacken nach der vorliegenden Neuerung.Figure 1 shows a schematic side view of a sealing jaw according to the present innovation.

Figur 2 zeigt die Draufsicht auf den Siegelbacken in Pfeilrichtung II in Figur 1.Figure 2 shows the top view of the sealing jaw in the direction of arrow II in Figure 1.

Figur 3 zeigt die Unteransicht des Siegelbackens nach Figur 1 in Pfeilrichtung III von Figur 1.Figure 3 shows the bottom view of the sealing jaw according to Figure 1 in the direction of arrow III of Figure 1.

Figur 4 zeigt einen oberen und unteren Siegelbacken beim Anbringen der Siegelnähte an einer Schlauchbeutelverpackung.Figure 4 shows an upper and lower sealing jaw when applying the sealing seams to a flow pack packaging.

Figur 5 zeigt schematisiert die gleichen Verhältnisse wie Figur 4 in nicht maßstabgerechter Darstellung Größendarstellungen.Figure 5 shows schematically the same relationships as Figure 4 in size representations not to scale.

Gemäss Figur 1 - 3 besteht der Siegelbacken 1 aus einem rechteckigen Metallkörper mit zueinander parallelen Backenaussenkanten 26. An der Oberseite weist der Siegelbacken 1 eine in Längsrichtung sich erstreckende zentrale Ausnehmung 4 auf, die in Richtung zur Siegelfläche 10 in eine schmälere Ausnehmung 5 übergeht. Diese Ausnehmung 5 ihrerseits geht in einen noch schmaler ausgebildeten Schlitz 6 über, in dem das Messer 14 verschiebbar angeordnet ist. Das Messer 14 ist hierbei an einem Messerhalter 15 befestigt, welcher in Pfeilrichtung 16 und in Gegenrichtung hierzu verschiebbar angetrieben ist.According to Figures 1 - 3, the sealing jaw 1 consists of a rectangular metal body with parallel outer jaw edges 26. On the top side, the sealing jaw 1 has a central recess 4 extending in the longitudinal direction, which merges into a narrower recess 5 in the direction of the sealing surface 10. This recess 5 in turn merges into an even narrower slot 6 in which the knife 14 is arranged so that it can move. The knife 14 is attached to a knife holder 15, which is driven so that it can move in the direction of the arrow 16 and in the opposite direction.

Es sind im übrigen im Körper des Siegelbackens 1 zwei zueinander parallele Längsbohrungen 3 vorhanden, in welche Heizkörper oder dergleichen Heizeinrichtungen eingebaut sind.Furthermore, there are two parallel longitudinal bores 3 in the body of the sealing jaw 1, into which radiators or similar heating devices are installed.

In der Nähe des Unterteils des Siegelbackens ist noch eine Fühlerbohrung 7 zum Einsetzen eines Temperaturfühlers angeordnet.Near the lower part of the sealing jaw there is a sensor hole 7 for inserting a temperature sensor.

An den oberen Seiten der Backenaussenkanten 26 sind Querbohrungen angeordnet, um Justierteile dort zu befestigen, um den Siegelbacken genau zu justieren.Cross holes are arranged on the upper sides of the jaw outer edges 26 in order to attach adjusting parts there in order to adjust the sealing jaw precisely.

Im übrigen ist eine mittlere Aufnahmebohrung 9 vorhanden, in welcher der Siegelbacken 1 in der Art einer Wippe verschwenkbar gehalten ist , um den Siegelbacken in Richtung zur Siegelfläche zu justieren.Furthermore, there is a central receiving bore 9 in which the sealing jaw 1 is pivotably held in the manner of a rocker in order to adjust the sealing jaw in the direction of the sealing surface.

In der Nähe der Siegelflächen 10 sind ferner zwei parallele, einen gegenseitigen Abstand zueinander einnehmende Längsbohrungen 27 vorhanden, die mit einem gut wärmeleitenden Material gefüllt sind, welches den Zweck hat, bei der Wärmeentnahme durch den Siegelvorgang von der Siegelfläche 10 weggehende Wärme schnell wieder nachfließen zu lassen.In the vicinity of the sealing surfaces 10 there are also two parallel longitudinal bores 27 which are spaced apart from one another and are filled with a material which conducts heat well and which has the purpose of allowing heat which escapes from the sealing surface 10 during the heat removal process to flow back in quickly.

Erfindungsgemäss ist die Backenbreite 23 des Siegelbackens 1 dadurch vermindert, daß zwar die Siegelbreite 19 gleich wie beim Stand der Technik in gleicher Breite vorgesehen ist, daß aber die Schlitzbreite wesentlich vermindert wird. Dies wird dadurch erreicht, daß ein dünneres Messer 14 verwendet wird und dementsprechend auch der Schlitz 6 für die Führung des Messers in der Breite vermindert ist.According to the invention, the jaw width 23 of the sealing jaw 1 is reduced in that the sealing width 19 is provided in the same width as in the prior art, but the slot width is significantly reduced. This is achieved by using a thinner knife 14 and accordingly the slot 6 for guiding the knife is also reduced in width.

Die Siegelfläche 10 wird also durch zwei Siegelflächen definiert, die voneinander durch die Schlitzbreite 25 getrennt sind.The sealing surface 10 is therefore defined by two sealing surfaces which are separated from each other by the slot width 25.

Aussen an jeder Siegelfläche 10 schließt sich eine Schräge 11 an , welche dazu führt, daß die Schiauchbeutelschräge 22 (vergl. Figur 5) praktisch vorspannungslos sich dort an diese Schräge 11 anpasst, weil die Schräge 11 in ihrem Winkel der Schiauchbeutelschräge 22 angepasst ist.On the outside of each sealing surface 10 there is a slope 11, which means that the hose bag slope 22 (see Figure 5) adapts to this slope 11 with practically no pre-stress, because the slope 11 is adapted in its angle to the hose bag slope 22.

Wenn eine derartige Schräge 11 nicht vorhanden wäre, dann würde die Folie im Bereich der Schi auchbeutelschräge 22 unerwünscht aufgetrenntIf such a slope 11 were not present, the film would be undesirably torn in the area of the ski bag slope 22

An die Schräge 11 schließt sich eine vertikale Gerade 12 an. Diese Gerade 12 dient dazu, noch genügend Material für das Unterteil 28 des Siegelbackens 1 zur Verfügung zu stellen, um zu gewährleisten, daß in diesem Unterteil 28 möglichst großvolumige Längsbohrungen 27 möglichst dicht an die Siegelfläche 10 angeordnet werden können.A vertical straight line 12 is connected to the slope 11. This straight line 12 serves to provide sufficient material for the lower part 28 of the sealing jaw 1 in order to ensure that longitudinal bores 27 of the largest possible volume can be arranged in this lower part 28 as close as possible to the sealing surface 10.

Jenseits der Gerade 12 schließt sich jeweils ein Radius 13 an, um einen günstigen Übergang in die Backenaussenkanten 26 zu gewährleisten.Beyond the straight line 12 there is a radius 13 in order to ensure a favorable transition into the jaw outer edges 26.

In den Figuren 2 und 3 sind im übrigen die gleichen Teile der Figur 1 mit den gleichen Bezugszahlen versehen.In Figures 2 and 3, the same parts as in Figure 1 are provided with the same reference numbers.

In der Figur 4 ist ein Siegelvorgang schematisiert erläutert. Hierbei ist erkennbar, daß einem oberen Siegelbacken 1 ein unterer Siegelbacken 2 gegenübersteht. Die Siegelbacken sind in ihren Aussenkonturen gleich ausgebildet. Der obere Siegelbacken 1 trägt das Messer 14, während der untere Siegelbacken 2 lediglich den Schlitz 6 für den Eintritt des Messers 14 beim Schneidevorgang aufweist.Figure 4 shows a schematic illustration of a sealing process. It can be seen that an upper sealing jaw 1 is opposite a lower sealing jaw 2. The sealing jaws have the same external contours. The upper sealing jaw 1 carries the knife 14, while the lower sealing jaw 2 only has the slot 6 for the knife 14 to enter during the cutting process.

Ansonsten sind die Siegelbacken 1,2 im wesentlichen identisch ausgebildet.Otherwise, the sealing jaws 1,2 are essentially identical.

Wichtig ist nun (vergl. hierzu auch Figur 5), daß die Schi auchbeutel schräge 22 sich in ihrer Neigung etwa der Schräge 11 anpasst, um eine Verletzung der Schiauchbeutelschräge 22 in diesem Bereich zu vermeiden.It is now important (see also Figure 5) that the slope of the ski bag 22 roughly matches the slope 11 in order to avoid damage to the slope of the ski bag 22 in this area.

Ferner ist wesentlich, daß nun die Siegelnähte 20 (wie in Figur 5 dargestellt) lediglich noch den verminderten Abstand um die Schlitzbreite 25 voneinander einnehmen, während in Figur 5 dargestellt ist, daß vorher nach dem Stand der Technik bekannte Siegelnähte 20a einen wesentlich größeren Abstand voneinander aufwiesen.Furthermore, it is important that the sealing seams 20 (as shown in Figure 5) now only occupy the reduced distance from one another by the slot width 25, while Figure 5 shows that previously known sealing seams 20a had a significantly greater distance from one another.

Damit war der Nachteil verbunden, daß die Schiauchbeutelschräge durch die weiter auseinanderliegenden Siegelnähte 20a (nach dem Stand der Technik) in unerwünschter Weise gestreckt und gestrafft wurden, wodurch eine Dichtheit der Siegelnaht 20 nicht immer gewährleistet werden konnte.This had the disadvantage that the hose bag slope was stretched and tightened in an undesirable manner by the further apart sealing seams 20a (according to the state of the art), whereby the tightness of the sealing seam 20 could not always be guaranteed.

In Figur 5 ist übertrieben die Länge des Endstückes 24 dargestellt, in dessen Bereich die Siegelnähte 20 angebracht sind. Dies erfolgt aus zeichnerischen Gründen; in Wirklichkeit ist das Endstück 24 wesentlich kürzer und geht jenseits der Siegelnähte 20 direkt in die Schiauchbeutelschräge 22 über.In Figure 5, the length of the end piece 24, in the area of which the sealing seams 20 are located, is shown exaggerated. This is done for graphic reasons; in reality, the end piece 24 is significantly shorter and, beyond the sealing seams 20, merges directly into the hose bag slope 22.

In dem Schlauchbeutel 17 sind z.B. scheibenförmige Produkte 18 stapeiförmig übereinander gelegt und werden über die beschriebenen Siegelnähte gasdicht eingesiedelt.In the tubular bag 17, for example, disc-shaped products 18 are stacked on top of each other and are sealed gas-tight via the described sealing seams.

Wichtig hierbei ist, daß die gesamten Schlauchbeutel 17 beispielsweise in Pfeilrichtung 21 durch die Siegelstation hindurchtransportiert werden.It is important here that the entire tubular bags 17 are transported through the sealing station, for example in the direction of arrow 21.
