Abstract

The device has two rotating sealing jaws (4) which subdivide a tubular foil into individual bags (8). One sealing jaw possesses centrally a zigzag-shaped knife. The other sealing jaw (4) has a corresponding stay (10). Recesses (20) are made in this sealing jaw. As a result of axial displacements, these recesses (20) can be displaced selectively into the region or outside the region of the knife during cutting, so that connecting webs (12) remain or a continuous severing cut is made. As a result, groups having any number of interconnected bags (8) can be formed in a simple way and so as to treat the products carefully. <IMAGE>

Description

Schlauchfolienbeutel werden zur Verpackung von Nahrungsmitteln, z.B. Schokoladeriegeln, vielfach verwendet. Es ist bekannt, Gruppen solcher Packungen zusammenhängend zu liefern, wobei die Trennschnitte bei den Quersiegelnähten nicht durchgehend sind, sodass mindestens zwei Verbindungsstege bestehen bleiben. Eine Vorrichtung zur Herstellung solcher Gruppen-Packungen ist in der CH-PS 574 844 beschrieben. Mit der Bildung der Quersiegelnaht wird gleichzeitig eine Schwächungslinie mittig in dieser Naht gequetscht. Die Packungen gelangen anschliessend auf ein rascher umlaufendes Förderband. Mit einer Walze können sie selektiv gegen das Band angedrückt werden, sodass die angedrückte Packung von der eben gebildeten Schwächungslinie abgerissen wird. Allerdings kann diese Vorrichtung nicht verwendet werden, wenn die verpackten Produkte druckempfindlich sind. Ausserdem ist die Beanspruchung der eben gebildeten Quersiegelnaht durch das Abreissen problematisch.Tubular film bags are widely used for packaging food, for example chocolate bars. It is known to supply groups of such packs in a coherent manner, the separating cuts not being continuous in the transverse sealing seams, so that at least two connecting webs remain. A device for producing such group packs is described in CH-PS 574 844. With the formation of the transverse sealing seam, a line of weakness is squeezed in the middle of this seam. The packs then go on a faster rotating conveyor belt. With a roller, they can be pressed selectively against the tape so that the pressed package is torn off the line of weakness just formed becomes. However, this device cannot be used if the packaged products are sensitive to pressure. In addition, the stress on the transverse seal just formed by tearing is problematic.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Die erfindungsgemässe Gruppenpackung ist im Anspruch 5 definiert.The present invention has for its object to design a device of the type mentioned in such a way that the above disadvantages are avoided. This object is achieved by the characterizing features of claim 1. The group pack according to the invention is defined in claim 5.

Die dargestellte Abtrennvorrichtung weist zwei übereinander liegende, gegenläufig rotierende Walzen 1 und 2 auf, die mit Siegelbacken 3, 4 bestückt sind, denen ein Schlauch 5 mittels eines nicht dargestellten Förderbandes oder dergleichen zugeführt wird. Der Schlauch 5 ist in bekannter Weise auf einer Schlauchbeutelmaschine so gebildet worden, dass er in regelmässigen Abständen voneinander Produkte 6, z.B. Schokoladeriegel, enthält. Durch Druck und/oder Wärme bilden die Siegelbacken 3, 4 im Schlauch zwischen je zwei Produkten 6 eine breite Quersiegelnaht 7, sodass eine Reihe von miteinander zusammenhängenden Schlauchpackungen 8 entsteht. Die Siegelbacke 3 ist in ihrer Mitte mit einem Messer 9 und die Siegelbacke 4 mit einem Gegenhalter 10 versehen. Das Messer 9 durchschneidet die Quernaht 7 bereits bei ihrer Entstehung in Längsrichtung der Naht 7. Der durch das Messer 9 bewirkte Schnitt 11 kann beispielsweise nur zwei schwache Verbindungsstege 12 zwischen den beiden Hälften der Naht 7 bestehen lassen. Das Messer 9 könnte stattdessen auch mehrere Stege 12 bestehen lassen.The separation device shown has two superimposed, counter-rotating rollers 1 and 2, which are equipped with sealing jaws 3, 4, to which a hose 5 is fed by means of a conveyor belt or the like, not shown. The tube 5 has been formed in a known manner on a tubular bag machine in such a way that it contains products 6, for example chocolate bars, at regular intervals from one another. Due to pressure and / or heat, the sealing jaws 3, 4 form a wide transverse sealing seam in the tube between two products 6 7, so that a series of interconnected hose packs 8 is formed. The sealing jaw 3 is provided in the middle with a knife 9 and the sealing jaw 4 with a counter holder 10. The knife 9 cuts through the transverse seam 7 as soon as it is formed in the longitudinal direction of the seam 7. The cut 11 caused by the knife 9 can, for example, leave only two weak connecting webs 12 between the two halves of the seam 7. Instead, the knife 9 could also have a plurality of webs 12.

Hinter dem Walzenpaar 1, 2 ist ein endloses Förderband 13 angeordnet, auf dessen oberem Trum die zusammenhängenden Schlauchpackungen 8 weiter befördert werden. Die Geschwindigkeit v₂ des Bandes 13 ist grösser als die Umfangsgeschwindigkeit v₁ der Siegelbacken 3, 4 bei der Nahtbildung. Die Walzen 1, 2 können, wie bekannt auch ungleichförmig rotieren.An endless conveyor belt 13 is arranged behind the pair of rollers 1, 2, on the upper run of which the connected hose packs 8 are conveyed further. The speed v₂ of the belt 13 is greater than the peripheral speed v₁ of the sealing jaws 3, 4 in the seam formation. As is known, the rollers 1, 2 can also rotate non-uniformly.

In Figur 2 ist ein Querschnitt durch die Walzen 1, 2 und Siegelbacken 3, 4 vergrössert dargestellt. Der Gegenhalter 10 hat mindestens zwei, im dargestellten Beispiel kegelstumpfförmige Ausnehmungen 20, die durch Relativbewegung zwischen den Walzen 1, 2 in den Bereich der Schnittkante 21 des Messers 9 oder ausserhalb des Bereichs dieser Schnittkante 21 bewegt werden können. Bei der in Figur 3 gezeigten Ausführungsform ist dazu die Walze 2 axial in zwei Stellungen verschiebbar, z.B. mittels eines Zylinderaggregates 22, das über einen Hebel 23 und einen Mitnehmer 24 in eine Nut 25 der Walzenachse 26 eingreift. Die Walzen 1, 2 sind über Zahnräder 27, 28 drehfest gegenläufig miteinander verbunden.In Figure 2, a cross section through the rollers 1, 2 and sealing jaws 3, 4 is shown enlarged. The counter-holder 10 has at least two, in the example shown frustoconical recesses 20, which can be moved by relative movement between the rollers 1, 2 in the area of the cutting edge 21 of the knife 9 or outside the area of this cutting edge 21. In the embodiment shown in Figure 3, the roller 2 is axially displaceable in two positions, for example by means of a cylinder unit 22 which engages via a lever 23 and a driver 24 in a groove 25 of the roller axis 26. The rollers 1, 2 are connected to one another in a rotationally fixed manner in opposite directions via gear wheels 27, 28.

Zur Herstellung von Gruppenpackungen mit Zick-Zack-Schnitt ist das Messer 9 zick-zack-förmig. In Figuren 4 und 5 ist der sich dabei ergebende Schnitt 11 der besseren Uebersicht wegen stark übertrieben gezeichnet. In der einen Axialstellung der Walze 2 sind die Ausnehmungen 20 des Gegenhalters 10 im Schnittbereich des Messers 9, sodass dort der Schnitt 11 nicht durchgeht und die Stege 12 stehenbleiben (Figur 4). Wird die Walze 2 in die andere axiale Stellung verschoben, ist der Schnitt 11 demgegenüber durchgehend und der vorangegangene Einzelbeutel oder die vorangegangene Gruppe von Beuteln wird abgetrennt (Figur 5).For the production of group packs with a zigzag cut, the knife 9 is zigzag-shaped. In FIGS. 4 and 5, the resulting section 11 is drawn in a greatly exaggerated manner for a better overview. In one axial position of the roller 2, the recesses 20 of the counter-holder 10 are in the cutting area of the knife 9, so that the cut 11 does not go through there and the webs 12 remain (FIG. 4). In contrast, if the roller 2 is shifted into the other axial position, the cut 11 is continuous and the previous single bag or the previous group of bags is separated (FIG. 5).

Figur 6 zeigt eine Variante, bei welcher der Schnitt 11 geradlinig ist, jedoch einen spitzen Winkel mit der Transportrichtung A bildet. Bei allen Varianten mit axialer Relativbewegung zwischen den Walzen 1, 2 sind die Stege 12 immer in einem Bereich der Schnittlinie 11, der einen spitzen Winkel mit der Transportrichtung A bildet. In Figur 6 ist zusätzlich die Längssiegelnaht 30 angedeutet.FIG. 6 shows a variant in which the section 11 is straight but forms an acute angle with the transport direction A. In all variants with an axial relative movement between the rollers 1, 2, the webs 12 are always in a region of the cutting line 11, which forms an acute angle with the transport direction A. The longitudinal sealing seam 30 is additionally indicated in FIG. 6.

Figuren 7 und 8 zeigen eine weitere Variante der Ausnehmungen 20 als seitliche, dreieckförmige Ausnehmungen 20' im Gegenhalter 10. Um eine grössere Anzahl Stege 12 zu bilden, wählt man die Anzahl Ausnehmungen nach Bedarf.FIGS. 7 and 8 show a further variant of the recesses 20 as lateral, triangular recesses 20 'in the counter-holder 10. In order to form a larger number of webs 12, the number of recesses is selected as required.

Mit der erfindungsgemässen Vorrichtung können auf sehr einfache Weise wahlweise Einzelbeutel oder Gruppen von einer wählbaren Anzahl zusammenhängender Einzelbeutel gebildet werden. Dazu wird die Walze 2 mittels des Zylinders 22 nach einer einstellbaren Anzahl Umdrehungen von der in Figur 4 gezeigten Position in die Position nach Figur 5 verschoben und nach einer Umdrehung wieder zurück zur Position nach Figur 4. Die Produkte 6 werden dabei nicht berührt, sodass mit der Vorrichtung auch druckempfindliche Produkte verarbeitet werden können. Die Umstellung auf eine andere Anzahl zusammenhängender Beutel ist sehr einfach.With the device according to the invention, individual bags or groups of a selectable number of connected single bags can be formed in a very simple manner. For this purpose, the roller 2 is adjustable by means of the cylinder 22 Number of revolutions shifted from the position shown in FIG. 4 into the position according to FIG. 5 and after one revolution back to the position according to FIG. 4. The products 6 are not touched, so that pressure-sensitive products can also be processed with the device. Switching to a different number of connected bags is very easy.

Abweichend von der beschriebenen Ausführungsform ist es auch möglich, die Ausnehmungen 20 durch relatives Verdrehen der Walzen 1, 2 gegeneinander in den Bereich oder ausserhalb des Bereichs des Messers 9 zu bringen. Dazu können zum Beispiel die Zahnräder 27, 28 durch ein Differentialgetriebe ersetzt werden, dessen dritte Welle mit einem Schwenkhebel verbunden ist, der in zwei Schwenkstellungen schwenkbar ist. In diesem Falle kann die Schnittlinie 11 auch gerade und senkrecht zur Transportrichtung A verlaufen.Deviating from the described embodiment, it is also possible to bring the recesses 20 into the area or outside the area of the knife 9 by rotating the rollers 1, 2 relative to one another. For this purpose, for example, the gears 27, 28 can be replaced by a differential gear, the third shaft of which is connected to a pivoting lever which can be pivoted in two pivoting positions. In this case, the section line 11 can also run straight and perpendicular to the transport direction A.

Es kann auch zweckmässig sein, die Ausnehmungen 20 anders als kegelstumpfförmig, z.B. pyramiden- oder prismenförmig oder als seitliche Ausnehmung 20' in gewünschter Form am Gegenhalter 10 auszubilden.It may also be expedient to design the recesses 20 other than frustoconical, e.g. pyramid-shaped or prism-shaped or as a lateral recess 20 'in the desired shape on the counter-holder 10.
