Die vorliegende Erfindung betrifft eine Verpackungsmaschine. Bei dieser The present invention relates to a packaging machine. At this

Verpackungsmaschine handelt es sich vorzugsweise um eine sogenannte FFS- Verpackungsmaschine, d. h. eine sogenannte Form-Fill-Seal-Verpackungsmaschine. Packaging machine is preferably a so-called FFS packaging machine, i. H. a so-called form-fill-seal packaging machine.

Bei einer derartigen Verpackungsmaschine wird eine Warenbahn taktweise entlang der Verpackungsmaschine transportiert. Bei jedem Takt wird mindestens eine, vorzugsweise ein Format bestehend aus mehreren Verpackungsmulden in eine Warenbahn, in der Regel einer Kunststofffolienbahn, beispielsweise durch Tiefziehen, geformt und nach dem Füllen der jeweiligen Verpackungsmulde mit einem Verpackungsgut, werden sie in einer Siegelstation mit einer Oberwarenbahn, bei der es sich in der Regel ebenfalls um eine In a packaging machine of this type, a web of material is transported in cycles along the packaging machine. At each cycle, at least one, preferably a format consisting of several packaging troughs is formed into a web, usually a plastic film web, for example by deep drawing, and after the respective packaging trough has been filled with a product, they are placed in a sealing station with a top web which is usually also a

Kunststofffolienbahn handelt, verschlossen. Jede Verpackung kann mehr als eine Plastic film web acts, closed. Each package can do more than one

Verpackungsmulde aufweisen. Diese Mehrzahl von Verpackungsmulden wird im Folgenden als„Submulden“ bezeichnet. Erfindungsgemäß sind mindestens zwei, vorzugsweise drei, vier, fünf oder mehr Submulden pro Verpackung vorhanden. Diese Submulden können mit demselben oder jeweils unterschiedlichen Verpackungsgütern bestückt sein. Beispielsweise kann sich in einer Submulde einer Verpackung Käse und in der anderen Submulde derselben Verpackung sich Wurst und/oder Schinken oder eine andere Käsesorte befinden. Die Oberwarenbahn kann ebenfalls tiefgezogen sein und somit mindestens einen Dom pro Verpackung aufweisen. In der Siegelstation wird die Oberwarenbahn stoffschlüssig, insbesondere durch Siegeln, mit der Unterwarenbahn verbunden. Vor dieser Verbindung werden die Verpackungssubmulden und/oder die Verpackungsmulde und der Dom einer Verpackung nun erfindungsgemäß ent- und/oder begast, wobei beim Entgasen ein gewisses Vakuum, d. h. ein gewisser Unterdrück in der Verpackungsmulde erzeugt wird. Beim Show packaging tray. This plurality of packaging trays is referred to below as "sub-trays". According to the invention there are at least two, preferably three, four, five or more sub-troughs per package. These sub-troughs can be equipped with the same or different packaging goods. For example, cheese and / or ham or another type of cheese can be located in one sub-trough of a packaging of cheese and in the other sub-trough of the same packaging. The upper fabric web can also be deep-drawn and thus have at least one dome per package. In the sealing station, the upper fabric web is cohesively connected to the lower fabric web, in particular by sealing. Before this connection the packaging troughs and / or the packaging trough and the dome of a packaging are now degassed and / or gassed according to the invention, with a certain vacuum, ie a certain suppression being generated in the packaging trough during degassing. At the

Begasen erfolgt ein Gasaustausch in der Verpackungsmulde, d. h. die Atmosphäre der Verpackungsmulde wird durch ein Austauschgas zumindest teilweise ersetzt. Dieser Gasaustausch kann sich an eine Entgasung der Verpackungsmulde anschließen. Bei dem Austauschgas kann es sich beispielsweise um Stickstoff, Kohlendioxid, Argon oder Fumigation involves a gas exchange in the packaging tray, i.e. H. the atmosphere of the packaging tray is at least partially replaced by an exchange gas. This gas exchange can follow a degassing of the packaging tray. The exchange gas can be, for example, nitrogen, carbon dioxide, argon or

Sauerstoff oder eine Mischung aus diesen oder anderen Gasen handeln. Nachdem die Oberwarenbahn stoffschlüssig an der Unterwarenbahn angeordnet ist, werden die so fertiggestellten Verpackungen anschließend aus den Warenbahnen vereinzelt, insbesondere herausgeschnitten. Dabei kann die Oberwarenbahn getrennt von der Unterwarenbahn durchtrennt werden. Es ist jedoch auch möglich die beiden Warenbahnen gleichzeitig zu durchtrennen. Act oxygen or a mixture of these or other gases. After the upper material web is arranged cohesively on the lower material web, the packaging thus finished is then separated, in particular cut out, from the material webs. The upper web can be cut separately from the lower web. However, it is also possible to cut the two webs at the same time.

Jede Submulde ist entlang einer Siegelnaht 26 mit einer Deckelfolie verschlossen. Im Eckbereich kann die Verpackungsmulde einen Öffnungsbereich aufweisen, in dem die Deckelfolie peelfähig an die Verpackungsmulde gesiegelt ist. Jede Submulde 23, 24 ist mit einem Verpackungsgut, insbesondere einem Lebensmittel gefüllt, wobei sich die Verpackungsgüter unterscheiden können. Beispielsweise sind in den Mulden unterschiedliche Käsesorten verpackt oder in einer Verpackungsmulde befindet sich Käse und in der anderen In the present case, the packaging tray 6 has two sub-trays 23, 24 which are connected to one another. The connection can be designed as a joint 25, or hinge, so that the two sub-troughs can be folded onto one another. Each sub-trough is closed along a sealing seam 26 with a cover film. In the corner area, the packaging tray can have an opening area in which the cover film is peelably sealed to the packaging tray. Each sub-trough 23, 24 is filled with a product to be packaged, in particular a food product, it being possible for the goods to be packaged to differ. For example, different types of cheese are packed in the troughs or there is cheese in one trough and the other in the other

beispielsweise Wurst oder Schinken. Erfindungsgemäß unterscheiden sich Gasatmosphären in den jeweiligen Submulden, beispielsweise in Form des vorherrschenden Drucks und/oder in Form der Gaszusammensetzung, voneinander. Vorzugsweise ist die jeweilige Atmosphäre in der jeweiligen Submulde an das dort befindliche Verpackungsgut angepasst, vorzugsweise für dieses optimiert. for example sausage or ham. According to the invention, gas atmospheres differ from one another in the respective sub-troughs, for example in the form of the prevailing pressure and / or in the form of the gas composition. The respective atmosphere is preferred adapted in the respective sub-tray to the packaging goods located there, preferably optimized for this.

Figur 3 zeigt ein Format von Verpackungsmulden, wie sie bereits anhand der Figur 2 beschrieben worden sind. In dem vorliegenden Fall weist das Format zwei Reihen und drei Spalten von Verpackungen auf, wobei sich die Reihen parallel zur Transportrichtung 28 der Unterwarenbahn 8 erstrecken. Die Spalten erstrecken sich quer zur Transportrichtung 28. Jede Verpackung ist in zwei Subreihen aufgeteilt. Diese Subreihen sind in der Figur und in den folgenden Figuren mit R1 bis R4 bezeichnet. FIG. 3 shows a format of packaging trays, as have already been described with reference to FIG. 2. In the present case, the format has two rows and three columns of packaging, the rows extending parallel to the transport direction 28 of the base fabric 8. The columns extend transversely to the transport direction 28. Each package is divided into two sub-rows. These sub-series are designated in the figure and in the following figures with R1 to R4.

Figur 4 zeigt das Formwerkzeug 4 zur Herstellung eines in Figur 3 dargestellten Formates. Dieses Format weist eine Vielzahl von Matrizen 30 auf, die entlang der Reihen R1 bis R4 angeordnet sind. Desweiteren weist das Formwerkzeug Lochmittel 31 , 32 auf, mit denen Begasungsöffnungen in die Unterwarenbahn 8 gestanzt werden, wobei die Stanzung nur teilweise erfolgt, so dass beim Stanzen keine losen Unterwarenbahnteile entstehen. Die Lochungen 31 befinden sich im Randbereich des Formates, während sich die Lochungen 32 im Innenbereich des Formates befinden. Die Lochungen 31 sind vorzugsweise als Linie angeordnet, während die Lochungen 32 beispielsweise als Dreieck oder dergleichen ausgebildet sind. FIG. 4 shows the molding tool 4 for producing a format shown in FIG. 3. This format has a plurality of matrices 30 arranged along the rows R1 to R4. Furthermore, the molding tool has perforation means 31, 32 with which gassing openings are punched into the base fabric 8, the stamping being carried out only partially, so that no loose base fabric parts are produced during the punching. The perforations 31 are located in the edge region of the format, while the perforations 32 are located in the inner region of the format. The perforations 31 are preferably arranged as a line, while the perforations 32 are designed, for example, as a triangle or the like.

In den Figuren 5 bis 7 sind Elemente einer ersten Siegelstation dargestellt, wobei Figur 5 die Siegelbrille 33, Figur 6 den Kammerdeckel 36 und Figur 7 das komplette Werkzeug darstellt. Die Siegelbrille 33 gemäß Figur 5 weist dem Format entsprechend Ausnehmungen 10 auf, die die Submulden 23, 24 jeweils aufnehmen können. Die Bohrungen 34 sind deckungsgleich mit den Bohrungen in der Unterwarenbahn 8 angeordnet, wobei bei dem ersten Siegelwerkzeug lediglich die Be- beziehungsweise Entgasungsbohrungen für den Randbereich der Unterwarenbahn 8 vorgesehen sind. Für die durch die Lochung 32 vorgenommenen Öffnungen in der Unterwarenbahn 8 gibt es keine entsprechenden FIGS. 5 to 7 show elements of a first sealing station, FIG. 5 the sealing goggles 33, FIG. 6 the chamber cover 36 and FIG. 7 the complete tool. The sealing glasses 33 according to FIG. 5 have cutouts 10 corresponding to the format, which the sub-troughs 23, 24 can each accommodate. The bores 34 are arranged congruently with the bores in the base fabric 8, with only the gassing or degassing holes being provided for the edge region of the base fabric 8 in the first sealing tool. There are no corresponding ones for the openings made in the bottom fabric web 8 through the perforation 32

Bohrungen in der Siegelbrille 33 dieser Siegelstation, so dass diese an der Bores in the sealing glasses 33 of this sealing station, so that these at the

Druckveränderung/Gasaustausch nicht teilnehmen. Figur 6 zeigt den Kammerdeckel 36 dieser Siegelstation. Dieser weist eine Siegelmaske 35 auf, an der Siegelmittel, Do not participate in pressure changes / gas exchange. FIG. 6 shows the chamber cover 36 of this sealing station. This has a sealing mask 35 on which sealing means,

insbesondere Siegelgummis, 39 vorgesehen sind. Diese Siegelmittel 39 sind nur im Bereich der Reihen R1 und R3 vorgesehen, so dass auch nur in diesen Reihen die Deckelfolie an die Verpackungsmulde gesiegelt wird. Desweiteren weist der Kammerdeckel ein Trennmittel 37, hier in Form eines Steges 37, auf, der das Siegelwerkzeug in zwei Bereiche aufteilt. Dadurch kann sichergestellt werden, dass die Reihen R1 und R3 unterschiedlich zumindest jedoch unabhängig voneinander be- beziehungsweise entgast werden können. Nach dies Be- beziehungsweise Entgasung wird das Siegelmittel 39 gegen die Siegelbrille 33 gedrückt und somit die Deckelfolie in den Reihen R1 und R3 mit den dort befindlichen in particular sealing rubbers, 39 are provided. These sealing means 39 are only provided in the area of the rows R1 and R3, so that the cover film is only sealed to the packaging tray in these rows. Furthermore, the chamber cover has a separating means 37, here in the form of a web 37, which divides the sealing tool into two areas. This can ensure that the rows R1 and R3 can be gassed or degassed differently, at least independently of one another. After this loading or degassing, the sealing means 39 is pressed against the sealing glasses 33 and thus the cover film in the rows R1 and R3 with those located there

Verpackungssubmulden verbunden. Packaging sub troughs connected.

Figur 7 zeigt eine Zusammenstellungszeichnung der Siegelstation. Deutlich sind die Figure 7 shows an assembly drawing of the sealing station. They are clear

Siegelbrille 33, die Siegelmaske 35 sowie der Steg 37 zu sehen. Die sich in den Sealing glasses 33, the sealing mask 35 and the web 37 can be seen. Which are in the

Ausnehmungen der Siegelbrille befindlichen Verpackungsmulden 6 sind gleichermaßen dargestellt. Recesses of the packaging troughs 6 in the sealing glasses are likewise shown.

In den Figuren 8 bis 10 sind Details der zweiten Siegelstation dargestellt, die sich vorzugsweise stromabwärts von der ersten Siegelstation relativ zu der Bewegungsrichtung der Unterwarenbahn 8 befindet. Im Wesentlichen kann auf die Ausführungen gemäß der Figuren 5 bis 7 Bezug genommen werden, wobei diese Siegelstation zusätzlich FIGS. 8 to 10 show details of the second sealing station, which is preferably located downstream of the first sealing station relative to the direction of movement of the base fabric 8. Essentially, reference can be made to the explanations according to FIGS. 5 to 7, this sealing station additionally

Abdeckungen 38, 40 aufweist, mit denen die in der ersten Siegelstation bereits Has covers 38, 40, with which already in the first sealing station

verschlossenen Submulden, insbesondere bezüglich in der zweiten Siegelstation sealed sub-troughs, particularly with regard to the second sealing station

vorhandenen gasseitigen Unter- beziehungsweise Überdrücken isoliert werden, um beispielsweise eine Beschädigung der bereits versiegelten Submulden zu verhindern. Die Abdeckungen 38 decken den Boden der jeweiligen Matrizen oberhalb derer sich bereits versiegelte Submulden befinden, ab. Die Abdeckungen 40 verschließen den Bereich oberhalb der Reihen, in den sich bereits fertig gestellte Submulden befinden. Dies sind in dem vorliegenden Fall die Reihen R1 und R3. In der zweiten Siegelmaske sind nunmehr auch Bohrungen zur Be- beziehungsweise Entgasung des Innenbereiches des Formates vorgesehen. Dies ist insbesondere in Figur 8 zu sehen. Figur 9 entspricht Figur 6, wobei in dem vorliegenden Fall nunmehr die Reihen R2 und R4 mit Siegelmitteln 39 versehen sind, um die Submulden in diesen Reihen mit der Deckelfolie zu verbinden. Der Kammerdeckel gemäß Figur 9 weist keinen Steg 37 auf. In Figur 10 ist die montierte Siegelstation zu sehen. Es ist deutlich zu erkennen, dass die Abdeckungen 38 den Boden unterhalb der existing gas-side negative or positive pressures are isolated, for example to prevent damage to the already sealed sub-troughs. The covers 38 cover the bottom of the respective matrices above which there are already sealed sub-hollows. The covers 40 close the area above the rows in which there are already finished sub-hollows. In the present case, these are the rows R1 and R3. In the second sealing mask, holes are now also provided for the degassing or degassing of the inner area of the format. This can be seen in particular in FIG. 8. FIG. 9 corresponds to FIG. 6, the rows R2 and R4 in the present case now being provided with sealing means 39 in order to connect the sub-troughs in these rows to the cover film. The chamber cover according to FIG. 9 has no web 37. The assembled sealing station can be seen in FIG. It can clearly be seen that the covers 38 cover the floor below the

Verpackungen 6 abdecken und die Abdeckungen 40 den Bereich oberhalb der Deckelfolie in den Reihen R1 und R3 isolieren. Lediglich die Reihen R2 können mittels der Löcher innerhalb des Formates und die Submulden in R4 mittels der Lochungen im Randbereich be beziehungsweise entgast werden. Nachdem dieser Gasaustausch stattgefunden hat, der sich bezüglich Druck- und/oder Gaszusammensetzung von der Atmosphäre in den Reihen R1 und R3 unterscheiden kann, wird die Deckelfolie an die Verpackungssubmulden gesiegelt. Cover packaging 6 and cover 40 isolate the area above the cover film in rows R1 and R3. Only the rows R2 can be degassed or degassed by means of the holes within the format and the sub-troughs in R4 by means of the holes in the edge area. After this gas exchange has taken place, which can differ from the atmosphere in rows R1 and R3 with regard to pressure and / or gas composition, the cover film is sealed to the packaging sub-troughs.

Die Abdeckungen 38, 40 sind vorzugsweise reversibel vorgesehen, so dass sie The covers 38, 40 are preferably provided so that they can be reversed
