The finished packaging is removed by means of an exit strip (17).

Description

VERPACKUNGSMASCHINE ZUM FORMEN UND SIEGELN VON VERPACKUNGSMULDEN PACKING MACHINE FOR MOLDING AND SEALING PACKING TIPS

Die vorliegende Erfindung betrifft eine Verpackungsmaschine mit mindestens einer Formstation zum Formen von Verpackungsmulden aus einer Folie, einer Schneidstation zum Zerschneiden der Folie zwischen den Verpackungsmulden, einer Füllstation zum Befüllen der Verpackungsmulde mit Verpackungsgut und einer Siegel-/Schneid-Station zum Siegeln der Verpackung mit einer Deckelfolie und Schneiden der Deckelfolie.The present invention relates to a packaging machine with at least one molding station for forming packaging trays from a film, a cutting station for cutting the film between the packaging trays, a filling station for filling the packaging tray with packaging material and a sealing / cutting station for sealing the packaging with a Cover film and cutting the cover film.

Traysealer, bei denen eine vorgefertigte Verpackungsmulde gefüllt und dann mit einer Deckelfolie gesiegelt wird, sind seit Jahren Stand der Technik. Traysealer haben jedoch den Nachteil haben, daß große Mengen an Verpackungsmulden vorgehalten werden müssen. Ferner kann auf kundenspezifische Änderungswünsche nicht schnell reagiert werden.Traysealers, in which a prefabricated packaging tray is filled and then sealed with a cover film, have been state of the art for years. However, traysealers have the disadvantage that large quantities of packaging trays have to be kept available. Furthermore, customer-specific change requests cannot be reacted to quickly.

Es stellte sich deshalb die Aufgabe, eine Verpackungsmaschine zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist.The object was therefore to provide a packaging machine which does not have the disadvantages of the prior art.

Gelöst wird die Aufgabe durch eine Verpackungsmaschine mit mindestens einer Formstation zum Formen von Verpackungsmulden aus einer Folie, einer Schneidstation zum Zerschneiden der Folie zwischen den Verpackungsmulden einer Befüllstation zum Befüllen der Verpackungsmulde mit Verpackungsgut und einer Siegel-/Schneid-Station zum Siegeln der Verpackung mit einer Deckelfolie und Schneiden der Deckelfolie, wobei die Schneidstation in die Formstation integriert ist oder nach der Formstation und vor der Füllstation angeordnet ist.The object is achieved by a packaging machine with at least one forming station for forming packaging trays from a film, a cutting station for cutting the film between the packaging trays, a filling station for filling the packaging tray with packaging material and a sealing / cutting station for sealing the packaging with a Cover film and cutting of the cover film, the cutting station being integrated in the forming station or being arranged after the forming station and before the filling station.

Es war für den Fachmann überaus erstaunlich, daß es mit dieser Vorrichtung gelingt, eine sehr flexible und einfache Verpackungsmaschine zur Verfügung zu stellen. Dadurch, daß die Verpackungsmulden online geformt werden, müssen diese nicht vorgehalten werden und es kann deren Form einfach durch Auswechseln der Werkzeuge in der Formstation verändert werden. Die erfindungsgemäße Verpackungsmaschine ist einfach und kostengünstig herzustellen. In einer bevorzugten Ausführungsform weist die erfindungsgemäße Verpackungsmaschine eine erste und eine zweite parallel laufende Linie auf, auf denen dieselben oder unterschiedliche Verpackungen hergestellt werden können. Diese Ausführungsform hat insbesondere den Vorteil, daß sie sehr flexibel ist. Je nach Auslassungsgrad können sehr viele Verpackungen einer Sorte oder unterschiedliche Verpackungen auf der jeweiligen Linie hergestellt werden. Es können auf den einzelnen Verpackungslinien sogar unterschiedliche Verpackungmaterialien je nach Anwendungsfall eingesetzt werden. Bei einem Werkzeugwechsel auf einer Linie läuft die andere Linie weiter, so daß es nie zu einem völligen Stillstand der erfindungsgemäßen Verpackungsmaschine kommt.It was extremely surprising to the person skilled in the art that this device succeeds in providing a very flexible and simple packaging machine. Because the packaging troughs are formed online, they do not have to be kept in stock and their shape can be changed simply by changing the tools in the forming station. The packaging machine according to the invention is simple and inexpensive to manufacture. In a preferred embodiment, the packaging machine according to the invention has a first and a second line running in parallel, on which the same or different packaging can be produced. This embodiment has the particular advantage that it is very flexible. Depending on the degree of omission, very many types of packaging or different types of packaging can be produced on the respective line. Different packaging materials can even be used on the individual packaging lines depending on the application. When a tool is changed on one line, the other line continues, so that the packaging machine according to the invention never comes to a complete standstill.

Vorzugsweise weist eine Linie eine Vorrichtung zum Plazieren von vorgefertigten Verpackungsmulden in dem Bereich der Füllstation auf. In diesem Fall wird diese Linie als reiner Traysealer betrieben und die Formstation nicht eingesetzt. Diese Ausführungsform erhöht die Flexibilität der Verpackungsmaschinen erheblich, weil eine Linie sowohl als sogenannter Thermoformer bei dem die Verpackungsmulden online hergestellt werden als auch als Traysealer betrieben werden kann.A line preferably has a device for placing prefabricated packaging trays in the area of the filling station. In this case, this line is operated as a pure traysealer and the forming station is not used. This embodiment increases the flexibility of the packaging machines considerably because a line can be operated both as a so-called thermoformer, in which the packaging troughs are produced online, and as a traysealer.

In einer bevorzugten Ausführungsform der vorliegenden Erfindung weist die Siegelstation zusätzlich eine Evakuierung auf, mit der die Umgebungsluft aus der Verpackung abgesaugt und vorzugsweise durch ein Inertgas ersetzt wird.In a preferred embodiment of the present invention, the sealing station additionally has an evacuation with which the ambient air is sucked out of the packaging and is preferably replaced by an inert gas.

Im folgenden wird die Erfindung anhand der FigurenIn the following the invention with reference to the figures

Figur 1 zeigt eine Seitenansicht der erfindungsgemäßen Verpackungsmaschine.Figure 1 shows a side view of the packaging machine according to the invention.

Figur 2 zeigt eine Draufsicht der erfindungsgemäßen Verpackungsmaschine.Figure 2 shows a plan view of the packaging machine according to the invention.

Figuren 3 - 5 zeigen mögliche Kombinationsmöglichkeiten der erfindungsgemäßen Verpackungsmaschine.FIGS. 3-5 show possible possible combinations of the packaging machine according to the invention.

Figur 1 zeigt eine Seitenansicht der erfindungsgemäßen Verpackungsmaschine 1. Von einer Folienrolle wird die Folie 11 in die Formstation 2 transportiert, dort erhitzt und mit dem Formwerkzeug 9 zu einer Verpackungsmulde, dem sogenannten Tray tiefgezogen. In dem vorliegenden Fall beinhaltet das Formwerkzeug auch eine Schneidvorrichtung, mit der die Verpackungsmulden 10 aus dem Folienband 11 ausgeschnitten werden. Das restliche Folienband 11 wird mit der Restgitteraufwicklung 13 aufgewickelt. Die so gefertigten Verpackungsmulden werden mit dem Transportband 14 in die Befüllstation 4 transportiert und dort mit Verpackungsgut befüllt. Die befüllten Verpackungsmulden werden dann in der Evakuier- und Siegelstation mit der Deckelfolie 12 geschlossen, indem diese auf die Verpackungsmulde 10 gesiegelt wird. In dem Siegelwerkzeug 15 ist ein Schneidsystem integriert, das die fertige Packung aus der Deckelfolie 12 ausschneidet. Die übrig bleibende Deckelfolie wird mit der Restgitteraufwicklung 16 aufgewickelt. Die fertige Verpackung wird mit dem Austragband 17 wegtransportiert. Der Fachmann weiß, daß kurz vor dem Siegeln die Gasatmosphäre in der befüllten Verpackung evakuiert und ggf. durch ein Inertgas ersetzt werden kann.FIG. 1 shows a side view of the packaging machine 1 according to the invention. The film 11 is transported from a film roll to the molding station 2, heated there and with the molding tool 9 to a packaging tray, the so-called tray deep-drawn. In the present case, the molding tool also includes a cutting device with which the packaging troughs 10 are cut out of the film strip 11. The remaining film strip 11 is wound up with the residual lattice take-up 13. The packaging troughs produced in this way are transported by the conveyor belt 14 to the filling station 4 and are filled there with packaging material. The filled packaging troughs are then closed in the evacuation and sealing station with the cover film 12 by sealing it onto the packaging trough 10. A cutting system is integrated in the sealing tool 15, which cuts out the finished package from the cover film 12. The remaining cover film is wound up with the remaining grid winder 16. The finished packaging is transported away with the discharge belt 17. The person skilled in the art knows that just before the sealing, the gas atmosphere in the filled packaging can be evacuated and, if necessary, replaced by an inert gas.

Figur 2 zeigt die Verpackungsmaschine gemäß Figur 1 in Draufsicht. Es ist zu erkennen, daß die Verpackungsmaschine aus zwei Linien 6, 7 besteht, auf der zwei unterschiedliche Verpackungsmulden 10, 10' gefertigt werden, die in der Befüllstation 4 mit unterschiedlichen Verpackungsgütern befüllt werden.Figure 2 shows the packaging machine according to Figure 1 in plan view. It can be seen that the packaging machine consists of two lines 6, 7, on which two different packaging trays 10, 10 'are produced, which are filled in the filling station 4 with different packaging goods.

In den Figuren 3 bis 5 ist die erfindungsgemäße Verpackungsmaschine schematisch in unterschiedlichen Konfigurationen dargestellt. Figur 3 zeigt eine Konfiguration, in der auf beiden Linien 6, 7 dieselbe Verpackungsmulde und damit dieselbe Verpackung hergestellt wird. Figur 4 zeigt eine Konfiguration, in der auf den Linien 6 und 7 unterschiedliche Verpackungen hergestellt werden. Figur 8 zeigt eine Konfiguration, in der die Formstation der Linie 7 nicht zum Einsatz kommt. Dafür werden mit einem Entstapler 8 vorgefertigte Verpackungsmulden auf das Transportband 14 gelegt und dort befüllt. Die Linie 6 funktioniert so wie zuvor beschrieben. Insbesondere die Ausführungsform gemäß Figur 5 zeigt die große Flexibilität der erfindungsgemäßen Verpackungsmaschine. Es können sowohl unterschiedliche Verpackungen insgesamt auf der Verpackungsmaschine hergestellt werden als auch nur vorgefertigte Verpackungsmulden zu fertigen Verpackungen komplettiert werden.
