A further evacuation and application of inert gas is effected in a second work region (6) before the packaging bases (2) are sealed by means of a cover material (15). The invention can be used in particular for the packaging of foodstuffs, for example coffee. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Verpacken von Waren.The invention relates to a method and an apparatus for packaging goods.

Die Art der Verpackung von Waren und die zur Verpackung angewandten physikalischen oder chemischen Prinzipien beeinflussen in hohem Maße die Lagerfähigkeit der Waren. Dies erweist sich insbesondere hei der Verpackung von Nahrungsmitteln als besonders wichtig, da viele Nahrungsmittel zu einer längeren Lagerung luftdicht von der Umgebung abgeschlossen werden müssen, um einen Verlust des Aromas zu vermeiden. Andererseits ist es bei vielen Nahrungsmitteln wünschenswert, die eigentliche Warenpackung zumindest teilluftdurchlässig auszugestalten, um durch einen vorbestimmbaren Luftaustausch beispielsweise den Feuchtigkeitsgehalt der Waren beeinflussen zu können. Als Beispiel für derartige Verpackungsproblematiken seien an dieser Stelle Kaffeebohnen genannt, welche üblicherweise in Beuteln gehandelt werden, die aus mit Aluminium kaschiertem Papier bestehen und nicht vollständig gasdicht abgeschlossen sind. Üblicherweise werden derartige Kaffeebeutel zum Verschließen an ihrem Einfüllbereich mehrfach umgeknickt, wobei der geknickte Bereich mittels einer Klebefolie gesichert wird. Bei diesen Verpackungen erweist es sich als nachteilig, daß das Aroma des Kaffees insbesondere bei längerer Lagerzeit entweicht.The type of packaging of goods and the physical or chemical principles used for packaging have a major influence on the shelf life of the goods. This proves to be particularly important in the packaging of foodstuffs, since many foods must be sealed airtight from the environment for longer storage in order to avoid loss of flavor. On the other hand, it is desirable for many foods to make the actual goods package at least partially permeable to air, in order to be able to influence the moisture content of the goods, for example, by a predeterminable air exchange. As an example of such packaging problems, coffee beans are mentioned at this point, which are usually traded in bags which are made of paper laminated with aluminum and not are completely gas-tight. Usually, such coffee bags are folded several times at their filling area, the folded area being secured by means of an adhesive film. With these packagings, it proves to be disadvantageous that the aroma of the coffee escapes, particularly when stored for a long time.

Die FR-A-2 277 531, die den Oberbegriff des Anspruchs 6 bildet zeigt eine Verpackungseinrichtung, bei welcher eine zu verpackende Ware in einen topfartigen Behälter eingefüllt, evakuiert, mit Inertgas beaufschlagt, nochmals evakuiert und mittels eines Deckels verschlossen wird. Es handelt sich hier somit um ein Verfahren zum Verpacken nur einer einzigen Charge einer Ware, die Sammelverpackung mehrerer bereits verpackter Waren ist nicht vorgeschlagen, so daß diese Druckschrift lediglich ein übliches Verpakkungsverfahren beschreibt.FR-A-2 277 531, which forms the preamble of claim 6, shows a packaging device in which a product to be packaged is filled into a pot-like container, evacuated, pressurized with inert gas, evacuated again and closed by means of a lid. It is therefore a process for packaging only a single batch of goods, the bulk packaging of several goods which have already been packaged is not proposed, so that this document only describes a conventional packaging process.

Aus der FR-A-1 115 890 ist eine Verpackungsvorrichtung bekannt, bei welcher einzelne, befüllte Verpackungen in ein Handhabungsgehäuse eingesetzt werden, welches dazu dient, diese einzelnen Verpackungen in rationellerer Weise zu evakuieren und zu verschließen. Das Handhabungsgerät dient nur zur gleichzeitigen Handhabung mehrerer einzelner Verpackungen, ein gemeinsames Einschließen oder Verpacken mehrerer bereits fertig verschlossener Verpackungen ist nicht vorgesehen.A packaging device is known from FR-A-1 115 890, in which individual, filled packages are inserted into a handling housing, which serves to more efficiently evacuate and seal these individual packages. The handling device is used only for the simultaneous handling of several individual packagings, a joint encapsulation or packing of several already closed packagings is not provided.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Verpacken von Waren zu schaffen, welche auch eine längerzeitige Lagerung der Waren ermöglichen und welche einfach und kostengünstig anwendbar sind.The invention has for its object to provide a method and an apparatus for packaging goods, which also enable long-term storage of the goods and which are simple and inexpensive to use.

Die Aufgabe wird durch die Merkmalskombinationen der Ansprüche 1 und 6 gelöst, die Unteransprüche zeigen jeweils vorteilhafte weitere Ausgestaltungen der Erfindung.The object is achieved by the combinations of features of claims 1 and 6, the subclaims each show advantageous further refinements of the invention.

Hinsichtlich des Verfahrens wird die Aufgabe dadurch gelöst, daß die Waren in teildichtverschlossene Packungen gefüllt werden, daß mehrere Packungen in ein Verpackungsunterteil eingesetzt werden, daß der Innenraum des Verpackungsunterteils auf maximal 60 % vorläufig evakuiert wird, worauf bei fortdauernder Evakuierung eine Spülung mit Inertgas erfolgt, und daß anschließend der Innenraum des Verpackungsunterteils nach einer erneuten, abschließenden Evakuierung mit Inertgas beaufschlagt und mittels eines Deckels versiegelt wird.With regard to the method, the object is achieved in that the goods are filled into partially sealed packs, that several packs are inserted into a lower packaging part, and the interior of the lower packaging part is provisionally evacuated to a maximum of 60%, followed by purging with inert gas if evacuation continues, and that after a further, final evacuation, the interior of the lower part of the packaging is then charged with inert gas and sealed by means of a cover.

Das erfindungsgemäße Verfahren zeichnet sich durch eine Reihe erheblicher Vorteile aus. Da die Waren selbst in teildichtverschlossene Packungen gefüllt werden, kann dieser Abfüllvorgang ohne zusätzliche Klimatisierung in normalen Arbeitsräumen durchgeführt werden. Die Abfüllung in teildichtverschlossene Packungen gestattet in gewissem Rahmen einen Gasaustausch, welcher beispielsweise zur Abgabe einer Restfeuchtigkeit erforderlich sein kann. Durch das anschließende Einsetzen mehrerer Packungen in ein Verpackungsunterteil ist es möglich, größere Gebinde zu erzeugen, beispielsweise mit Einheiten von 8 bis 12 Warenpackungen, welche zum einen leichter transportierbar sind und zum anderen den weiteren Verpackungsaufwand wesentlich erniedrigen. Durch die weitere verfahrensgemäße Beeinflussung des Innenraums des Verpackungsunterteiles ist es möglich, die in dem Verpackungsunterteil und den teildichtverschlossenen Packungen eingeschlossenen Gase gezielt hinsichtlich ihrer Art und Zusammensetzung zu steuern. Erfindungsgemäß wird der Innenraum des Verpackungsunterteils zunächst auf maximal 60% evakuiert. Dies ermöglicht zum einen eine wirkungsvolle Entfernung der in dem Innenraum des Verpackungsunterteils befindlichen Gase, zum anderen ist es möglich, auch die in den Warenpackungen eingeschlossenen Gase abzusaugen. Durch die Begrenzung der Evakuierung auf maximal 60% ist sichergestellt, daß die einzelnen Warenpackungen während der Evakuierung nicht platzen, was bei einer stärkeren Evakuierung durch die in den Warenpackungen eingeschlossene Luft möglich wäre. Nachdem der Innenraum des Verpackungsunterteils evakuiert wurde, erfolgt erfindungsgemäß zusätzlich zu der weiter vorgenommenen Evakuierung eine Spülung mit Inertgas. Durch diese Maßnahme wird ein Austausch der noch in den Warenpackungen verbliebenen Gase gegen das Inertgas vorgenommen. Dadurch läßt sich der Restsauerstoffgehalt der in den Warenpackungen befindlichen Gase auf unter 1% verringern, wodurch ein Oxidierung der Waren während einer längeren Lagerzeit wirkungsvoll vermieden werden kann.The method according to the invention is distinguished by a number of considerable advantages. Since the goods themselves are filled in partially sealed packages, this filling process can be carried out in normal work rooms without additional air conditioning. Filling into partially sealed packages allows a certain amount of gas exchange, which may be necessary, for example, to release residual moisture. By subsequently inserting several packs into a lower packaging part, it is possible to produce larger containers, for example with units of 8 to 12 packs of goods, which on the one hand are easier to transport and on the other hand significantly reduce the further packaging effort. By further influencing the interior of the lower part of the packaging according to the method, it is possible to control the gases enclosed in the lower part of the packaging and the partially sealed packs in a targeted manner with regard to their type and composition. According to the invention, the interior of the lower packaging part is first evacuated to a maximum of 60%. On the one hand, this enables an effective removal of the gases located in the interior of the lower packaging part, on the other hand, it is also possible to suck off the gases enclosed in the goods packs. By the limitation The evacuation to a maximum of 60% ensures that the individual packs of goods do not burst during the evacuation, which would be possible with a stronger evacuation due to the air enclosed in the packs of goods. After the interior of the lower packaging part has been evacuated, purging with inert gas takes place according to the invention in addition to the further evacuation. As a result of this measure, the gases still remaining in the goods packs are exchanged for the inert gas. As a result, the residual oxygen content of the gases in the goods packs can be reduced to less than 1%, as a result of which oxidation of the goods during an extended storage period can be effectively avoided.

Bei dem nachfolgenden Befüllen oder Beaufschlagen des Innenraums des Verpackungsunterteils mit Inertgas und dem anschließenden Versiegeln mittels eines Deckels wird sichergestellt, daß keine verunreinigten Gase in dem nunmehr luftdicht verschlossenen Verpackungsunterteil befindlich sind und daß der zuvor minimierte Sauestoffgehalt weiterhin auf diesem niedrigen Wert beibehalten werden kann.During the subsequent filling or loading of the interior of the lower packaging part with inert gas and the subsequent sealing by means of a lid, it is ensured that there are no contaminated gases in the now airtightly sealed lower packaging part and that the previously minimized oxygen content can still be maintained at this low value.

Eine günstige Weiterbildung des erfindungsgemäßen Verfahrens ist dadurch gegeben, daß die vorläufige Evakuierung und Spülung mit Inertgas mehrfach durchgeführt werden. Durch diese mehrfache Wiederholung dieses Arbeitsschrittes kann der Restsauerstoffgehalt im Inneren der teilverschlossenen Warenpackungen auf einen Minimalwert gesenkt werden.A favorable further development of the method according to the invention is provided in that the preliminary evacuation and flushing with inert gas are carried out several times. By repeating this step several times, the residual oxygen content inside the partially sealed goods packages can be reduced to a minimum value.

Weiterhin kann es sich als vorteilhaft erweisen, daß nach der vorläufigen Evakuierung und Spülung mit Inertgas ein vorläufiger Verschluß des Verpackungsunterteils erfolgt. Falls als Inertgas nicht ein Gas verendet wird, welches schwerer als Luft ist, könnte bei einem Wechsel der Verpackungsunterteile zwischen den verschiedenen Verarbeitungsbereichen oder bei einer Undichtigkeit des Werkzeuges das Inertgas durch Luft ausgetauscht werden, wodurch der erfindungsgemäße günstige Effekt verringert oder beseitigt würde. Um dem vorzubeugen, kann das Verpackungsunterteil mittels eines vorläufigen Verschlusses, beispielsweise einer versiegelten Folie, verschlossen werden. Bei Verwendung eines Inertgases, welches ein höheres spezifisches Gewicht als Luft aufweist, kann dieser vorläufige Verschluß entfallen.Furthermore, it can prove to be advantageous that after the preliminary evacuation and flushing with inert gas, the lower part of the packaging is temporarily sealed. If a gas that is heavier than air is not used as the inert gas, a change in the packaging parts between the different processing areas or in one Leakage of the tool, the inert gas can be exchanged for air, which would reduce or eliminate the favorable effect according to the invention. In order to prevent this, the lower part of the packaging can be closed by means of a temporary closure, for example a sealed film. When using an inert gas which has a higher specific weight than air, this provisional closure can be omitted.

In einer besonders günstigen Weiterbildung des erfindungsgemäßen Verfahrens erfolgt die vorläufige Evakuierung auf Werte zwischen 40 und 60 %. Wie bereits beschrieben, erweist sich eine Evakuierung auf Werte über 60 % wegen der Gefahr des Berstens der Warenpackungen als ungünstig. Bei einer Evakuierung unter 40 % wäre nicht sichergestellt, daß die erfindungsgemäßen Vorgänge, d.h. der Austausch der Luft gegen das Inertgas, in zuverlässiger Weise ablaufen.In a particularly advantageous development of the method according to the invention, the preliminary evacuation to values between 40 and 60% takes place. As already described, an evacuation to values over 60% proves to be unfavorable because of the risk of the goods packs bursting. With an evacuation below 40% it would not be ensured that the processes according to the invention, i.e. the exchange of air for the inert gas, run in a reliable manner.

Eine besonders vorteilhafte Weiterbildung der Erfindung kann auch dadurch gegeben sein, daß vor dem Verschließen des Verpackungsunterteils mittels des Deckels und der zuvor erfolgenden Inertgasbeaufschlagung eine abschließende Evakuierung auf maximal 60 % erfolgt. Durch diese Maßnahme wird eine nochmalige, möglichst vollständige Beaufschlagung mit Inertgas hervorgerufen, um den Restsauerstoffgehalt bzw. den Gehalt "unreiner" Gase in den Verpackungen weiter zu minimieren.A particularly advantageous development of the invention can also be given in that a final evacuation to a maximum of 60% takes place before the lower part of the packaging is closed by means of the cover and the inert gas applied beforehand. As a result of this measure, a further, as complete as possible, exposure to inert gas is brought about in order to further minimize the residual oxygen content or the content of "impure" gases in the packaging.

Bezüglich der Vorrichtung wird die erfindungsgemäße Aufgabe dadurch gelöst, daß eine Transporteinrichtung zur Durchführung von mit Warenpackungen gefüllten Verpackungsunterteilen durch die Vorrichtung vorgesehen ist, sowie ein erster Arbeitsbereich mit einer Vakuumquelle und einer Inertgaszufuhr und ein zweiter Arbeitsbereich mit einer Deckelzuführeinrichtung, einer Versiegelungseinrichtung, einer Vakuumquelle und einer Inertgaszufuhr. Die erfindungsgemäße Vorrichtung zeichnet sich durch eine Reihe erheblicher Vorteile aus. Durch die Trennung in einen ersten und einen zweiten Arbeitsbereich ist es möglich, diese den jeweiligen Anforderungen in bestmöglicher Weise anzupassen, wobei insbesondere die Fördergeschwindigkeit der Verpackungsunterteile in optimaler Weise an die Dauer der ablaufenden physikalischen Prozesse angepaßt werden kann. Da in dem ersten Arbeitsbereich lediglich eine Vakuumquelle und eine Inertgaszufuhr erforderlich sind, ist es möglich, diesen ersten Arbeitsbereich konstruktiv besonders zu optimieren und entsprechend betriebssicher auszubilden. Weiterhin ist es möglich, mehrere dieser einfach auszugestaltenden Arbeitsbereiche vorzusehen, in welchen für die Evakuierung und Spülung, angepaßt an die Fördergeschwindigkeit der Verpackungsunterteile, ausreichend Zeit zur Verfügung steht. Da erfindungsgemaß in dem zweiten Arbeitsbereich die Versiegelung der Verpackungsunterteile erfolgt, muß dieser in geeigneter Weise zusätzlich mittels einer Versiegelungseinrichtung und einer Deckelzuführeinrichtung versehen sein. Da das Versiegeln nur eine relativ kurze Verarbeitungszeit erfordert, ist es möglich, zusätzlich zu mehreren ersten Arbeitsbereichen lediglich einen zweiten Arbeitsbereich vorzusehen.With regard to the device, the object according to the invention is achieved in that a transport device is provided by the device for carrying out packaging lower parts filled with product packs, as well as a first working area with a vacuum source and an inert gas supply and a second Work area with a lid feed device, a sealing device, a vacuum source and an inert gas feed. The device according to the invention is distinguished by a number of considerable advantages. The separation into a first and a second work area makes it possible to adapt them to the respective requirements in the best possible way, in particular the conveying speed of the lower packaging parts can be optimally adapted to the duration of the physical processes taking place. Since only a vacuum source and an inert gas supply are required in the first working area, it is possible to optimize this first working area in terms of construction and to design it to be correspondingly reliable. Furthermore, it is possible to provide several of these easily designed work areas, in which sufficient time is available for evacuation and flushing, adapted to the conveying speed of the lower packaging parts. Since, according to the invention, the packaging lower parts are sealed in the second working area, this must be additionally provided in a suitable manner by means of a sealing device and a lid feed device. Since the sealing only requires a relatively short processing time, it is possible to provide only a second working area in addition to several first working areas.

Bei der erfindungsgemäßen Vorrichtung erweist es sich, ebenso wie bei dem erfindungsgemäßen Verfahren als vorteilhaft, wenn als Inertgas CO₂ verwendet wird, da dieses Gas zu geringen Kosten zur Verfügung steht und einfach handhabbar ist.In the device according to the invention, as well as in the method according to the invention, it proves advantageous if CO₂ is used as the inert gas, since this gas is available at low cost and is easy to handle.

In einer weiteren vorteilhaften Ausgestaltung ist das Verpackungsunterteil jeweils in dem ersten und dem zweiten Arbeitsbereich in einer ersten bzw. einer zweiten Arbeitskammer einschließbar, wobei diese Arbeitskammern jeweils mit einer Vakuumquelle und einem Inertgasanschluß versehen sind. Während der Behandlung und Verarbeitung der Verpackungsunterteile wird somit ein unerwünschter Gasaustausch zur Umgebung hin verhindert.In a further advantageous embodiment, the lower packaging part is in the first and the second working area in a first and a second working chamber enclosable, these working chambers are each provided with a vacuum source and an inert gas connection. During the treatment and processing of the lower packaging parts, an undesired gas exchange to the environment is prevented.

Bei der erfindungsgemäßen Vorrichtung erweist es sich weiterhin als günstig, wenn jede der Arbeitskammern ein höhenveränderbares Kammerunterteil aufweist. Durch diese Maßnahme ist es möglich, die Verpackungsunterteile im wesentlichen in einer Ebene, d.h. ohne Überwindung von Höhenunterschieden, zu fördern. Dies erweist sich insbesondere dann als besonders vorteilhaft, wenn mehrere Verpackungsunterteile eine zusammenhängende Bahn bilden, da dann keine Umlenkung dieser Bahn erforderlich ist.In the device according to the invention it also proves to be advantageous if each of the working chambers has a height-adjustable lower part of the chamber. With this measure it is possible to move the lower packaging parts essentially in one plane, i.e. without overcoming height differences. This proves to be particularly advantageous if several lower packaging parts form a coherent web, since then no deflection of this web is required.

Eine besonders vorteilhafte Weiterbildung ist auch dadurch gegeben, daß die Deckelzuführeinrichtung in Form einer Folienbahnzuführung ausgebildet ist. Somit ist es nicht erforderlich, einzelne Deckel separat zuzuführen. Weiterhin erweist es sich als vorteilhaft, wenn die Folienbahn und der Schweißstempel die gleiche Breite aufweisen, wobei dann zwischen dem Schweißstempel und der Innenwandung des Kammeroberteils ein Freiraum gebildet wird, welcher mit einer Vakuumquelle in Verbindung steht. Dadurch ist sichergestellt, daß bei bereits zugeführter Folienbahn, jedoch vor dem Versiegeln mittels des Schweißstempels, ein ausreichender Gasaustausch mit dem Innenraum des Verpackungsunterteils erfolgt.A particularly advantageous development is also given in that the cover feed device is designed in the form of a film web feed. It is therefore not necessary to feed individual lids separately. Furthermore, it proves to be advantageous if the film web and the welding stamp have the same width, a free space then being formed between the welding stamp and the inner wall of the upper chamber part, which is connected to a vacuum source. This ensures that when the film web is already fed in, but before sealing by means of the welding stamp, there is sufficient gas exchange with the interior of the lower packaging part.

Im Bereich der zweiten Arbeitskammer erfolgt die Inertgaszufuhr bevorzugterweise mittels einer Schlitzdüse, welche zwischen dem in dem Kammerunterteil angeordneten Verpackungsunterteil und der mittels der Schlitzdüse an das Kammeroberteil angelegten Folienbahn angeordnet ist. Durch diese Maßnahme wird erreicht, daß das Inertgas direkt in den Innenraum des Verpackungsunterteils einströmt, so daß eine zuverlässige und betriebssichere Beaufschlagung gewährleistet ist. Die Schlitzdüse kann zur Erhöhung der Durchflußmenge mit mehreren Inertgasanschlüssen versehen sein.In the area of the second working chamber, the inert gas is preferably supplied by means of a slot nozzle which is placed between the lower packaging part arranged in the lower chamber part and the upper part of the chamber which is positioned by means of the slot nozzle Foil sheet is arranged. This measure ensures that the inert gas flows directly into the interior of the lower packaging part, so that a reliable and reliable loading is ensured. The slot nozzle can be provided with several inert gas connections to increase the flow rate.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles in Verbindung mit der Zeichnung beschrieben. Dabei zeigt:

The invention is described below using an exemplary embodiment in conjunction with the drawing. It shows:
Fig. 1
is a schematic side view, partly in section, of the first and second work area of the device according to the invention and
Fig. 2
a sectional view taken along the line II-II of Fig. 1st

In Fig. 1 ist in schematischer Weise eine Seitenansicht der erfindungsgemäßen Vorrichtung zum Verpacken von Waren dargestellt. Die Waren sind in einzelnen Warenpackungen 1 abgefüllt, welche teildichtverschlossen sind und beispielsweise aus aluminiumkaschiertem Papiermaterial bestehen, welches durch mehrfaches Knicken verschlossen wird. Bei den eingeschlossenen Waren kann es sich beispielsweise um Kaffeebohnen handeln.In Fig. 1, a side view of the device for packaging goods according to the invention is shown schematically. The goods are filled in individual goods packs 1, which are partially sealed and consist, for example, of aluminum-laminated paper material, which is closed by multiple folding. The included goods can be coffee beans, for example.

Die einzelnen Warenpackungen 1 sind jeweils zu mehreren in einem Verpackungsunterteil 2 angeordnet. Die einzelnen Verpackungsunterteile 2 sind napf- oder wannenförmig ausgebildet und sind untereinander an ihren Flanschbereichen 2a verbunden. Das somit gebildete Band aus mehreren Verpackungsunterteilen wird im wesentlichen in einer Ebene mittels einer geeigneten Fördereinrichtung, beispielsweise eines Kettenförderers, bewegt, bei dem in Fig. 1 gezeigten Ausführungsbeispiel von rechts nach links. Jedes der Verpakkungsunterteile 2 weist einen Innenraum 3 auf, welcher so dimensioniert ist, daß die einzelnen Warenpackungen 1 leicht einsetzbar sind, wobei auch bei eingesetzten Warenpackungen 1 noch ein Innenraum 3 bestehen bleibt.The individual goods packs 1 are each arranged in a plurality in a lower packaging part 2. The individual packaging lower parts 2 are cup-shaped or trough-shaped and are connected to one another at their flange regions 2a. The band thus formed from a plurality of lower packaging parts is moved essentially in one plane by means of a suitable conveying device, for example a chain conveyor, in the exemplary embodiment shown in FIG. 1 from right to left. Each of the lower packaging parts 2 has an inner space 3 which is dimensioned such that the individual goods packs 1 are easy to use, an inner space 3 still remaining even when the goods packs 1 are inserted.

Die erfindungsgemäße Vorrichtung weist einen ersten Arbeitsbereich 5 und einen zweiten Arbeitsbereich 6 auf.The device according to the invention has a first working area 5 and a second working area 6.

In dem ersten Arbeitsbereich 5 ist eine erste Arbeitskammer 7 zur Aufnahme eines Verpackungsunterteils 2 ausgebildet, welche von einem im wesentlichen feststehenden Deckel 9 und einem höhenveränderbar gelagerten Kammerunterteil 10 umschlossen wird. Zur Einführung des jeweiligen Verpackungsunterteils 2 wird das Kammerunterteil 10 abgesenkt, um anschließend, wenn das Verpackungsunterteil 2 in seine Verarbeitungsposition gebracht wurde, nach oben gegen den Deckel 9 in Anlage gebracht zu werden. Bei dem in Fig. 1 gezeigten Betriebszustand liegt der Deckel 9 gegen den Flanschbereich 2a des Verpackungsunterteils 2 an, welcher wiederum von dem Kammerunterteil 10 abgestützt wird. Somit wird die erste Arbeitskammer 7 in zwei Teilbereiche unterteilt, wobei der in Fig. 1 gezeigte untere Teilbereich für die weitere Verarbeitung nicht relevant ist.In the first working area 5, a first working chamber 7 is formed for receiving a lower packaging part 2, which is enclosed by an essentially fixed cover 9 and a height-adjustable lower chamber part 10. For the introduction of the respective lower packaging part 2, the lower chamber part 10 is lowered, in order then, when the lower packaging part 2 has been brought into its processing position, to be brought up against the cover 9. In the operating state shown in FIG. 1, the cover 9 bears against the flange region 2a of the lower packaging part 2, which in turn is supported by the lower chamber part 10. The first working chamber 7 is thus divided into two partial areas, the lower partial area shown in FIG. 1 not being relevant for further processing.

Im Bereich des Deckels 9 ist ein Auslaß 17 vorgesehen, welcher mit einer nicht dargestellten Vakuumquelle in Verbindung steht. Weiterhin weist der Deckel 9 einen Einlaß 18 auf, durch welchen Inertgas zuführbar ist. Es ist somit möglich, den oberhalb des Verpackungsunterteils 2 ausgebildeten Teilbereich 7a der ersten Arbeitskammer 7 zu evakuieren und/oder mit Inertgas zu befüllen.In the area of the cover 9, an outlet 17 is provided, which is connected to a vacuum source, not shown. Furthermore, the cover 9 has an inlet 18 through which inert gas can be supplied. It is thus possible to evacuate the portion 7a of the first working chamber 7 formed above the lower packaging part 2 and / or to fill it with inert gas.

Nach erfolgter Behandlung der Warenpackungen 1 in der ersten Arbeitskammer 7 wird der zugehörige Verpackungsunterteil 2 in den zweiten Arbeitsbereich 6 überführt. Dieser zweite Arbeitsbereich 6 umfaßt eine zweite Arbeitskammer 8, welche von einem Kammerunterteil 11 und einem Kammeroberteil 12 gebildet wird. Das Kammerunterteil 11 ist, ebenso wie das Kammerunterteil 10, höhenveränderbar gelagert, so daß die jeweilige Flanschbereiche 2a der Verpackungsunterteile 2 in dichtende Anlage an das Kammeroberteil 12 gedrückt werden können, wodurch ein in dem Kammeroberteil 12 ausgebildeter Innenraum 13 mit den Warenpackungen 1 in Verbindung steht und evakuierbar bzw. mit Inertgas beaufschlagbar ist. In dem Innenraum 13 ist ein Schweißstempel 14 angeordnet, welcher hydraulisch oder durch Druckluftbetätigung mittels eines Kolbens 19 relativ zu dem Kammeroberteil 12 höhenverstellbar ist. Der Schweißstempel 14 weist einen zur Versiegelung dienenden Randbereich 14a auf.After the goods packs 1 have been treated in the first working chamber 7, the associated lower packaging part 2 is transferred to the second working area 6. This second working area 6 comprises a second working chamber 8, which is formed by a lower chamber part 11 and an upper chamber part 12. The lower chamber part 11, like the lower chamber part 10, is mounted such that it can be adjusted in height, so that the respective flange regions 2a of the lower packaging parts 2 can be pressed in sealing contact with the upper chamber part 12, as a result of which an interior space 13 formed in the upper chamber part 12 is connected to the goods packs 1 and can be evacuated or charged with inert gas. By doing Interior 13 a welding stamp 14 is arranged, which can be adjusted hydraulically or by compressed air actuation by means of a piston 19 relative to the upper chamber part 12. The welding stamp 14 has an edge region 14a which serves for sealing.

Im Einlaufbereich der zweiten Arbeitskammer 8, d. h. an der in Fig. 1 gezeigten rechten Seite ist eine Schlitzdüse 16 vorgesehen, welche in nicht dargestellter Weise mit einer Inertgasversorgung verbunden ist. Die Schlitzdüse 16 und das Kammeroberteil 12 sind paßgenau zueinander ausgebildet, so daß der Innenraum 13 zur Umgebung hin abgedichtet ist.In the inlet area of the second working chamber 8, i. H. A slot nozzle 16 is provided on the right-hand side shown in FIG. 1, which is connected in a manner not shown to an inert gas supply. The slot nozzle 16 and the upper chamber part 12 are designed to fit each other so that the interior 13 is sealed off from the environment.

Weiterhin ist im Bereich des Kammeroberteils 12 eine im einzelnen nicht dargestellte Zuführeinrichtung für eine Folienbahn 15 vorgesehen, welche der Versiegelung oder Verschließung der Verpackungsunterteile 2 dient. Außerdem weist das Kammeroberteil 12 einen Auslaß 20 auf (siehe Fig. 2), welcher mit einer Vakuumquelle verbunden ist.Furthermore, a feed device (not shown in detail) for a film web 15 is provided in the area of the upper chamber part 12, which serves to seal or close the lower packaging parts 2. In addition, the upper chamber part 12 has an outlet 20 (see FIG. 2) which is connected to a vacuum source.

Die Folienbahn 15 ist in ihrer Breite so bemessen, daß sie der Breite des Schweißstempels 14 gleich ist (siehe Fig. 2). Auf diese Weise wird zwischen der in Verschließstellung gebrachten Folienbahn 15 und dem Flansch 2a des Verpackungsunterteils 2 ein Zwischenraum 21 ausgebildet, welcher einen Gasaustausch zwischen dem Innenraum 3 des jeweiligen Verpackungsunterteils 2 und dem Innenraum 13 des Kammeroberteils 12 ermöglicht.The width of the film web 15 is dimensioned such that it is equal to the width of the welding stamp 14 (see FIG. 2). In this way, an intermediate space 21 is formed between the film web 15 brought into the closed position and the flange 2a of the lower packaging part 2, which enables gas exchange between the interior 3 of the respective lower packaging part 2 and the interior 13 of the upper chamber part 12.

Bei dem in Fig. 2 gezeigten Betriebszustand ist das Kammerunterteil 11 abgesenkt worden, um das Verpackungsunterteil 2 in die zweite Arbeitskammer 8 einzubringen.In the operating state shown in FIG. 2, the lower chamber part 11 has been lowered in order to introduce the lower packaging part 2 into the second working chamber 8.

In dem zweiten Arbeitsbereich 6 wird, nachdem das Verpakkungsunterteil 2 eingeführt und die zweite Arbeitskammer 8 zur Umgebung hin abgedichtet wurde, über den Auslaß 20 ein Vakuum angelegt, während gleichzeitig oder zeitversetzt durch die Schlitzdüse 16 ein Inertgas zugeführt wird. Nachdem dieses Verfahren über einen ausreichenden Zeitraum durchgeführt wurde, wird mittels des Kolbens 19 der Schweißstempel 14 abgesenkt, so daß die Folienbahn 15 mit dem Flanschbereich 2a des Verpackungsunterteils 2 luftdicht versiegelt werden kann. Zu diesem Zweck kann der Schweißstempel 14 in üblicher Weise beheizbar ausgebildet sein.In the second working area 6, after the packaging lower part 2 has been introduced and the second working chamber 8 has been sealed off from the environment, an inlet 20 is used Vacuum applied while an inert gas is supplied through the slot nozzle 16 simultaneously or with a time delay. After this method has been carried out for a sufficient period of time, the welding stamp 14 is lowered by means of the piston 19, so that the film web 15 can be sealed airtight with the flange region 2a of the lower packaging part 2. For this purpose, the welding stamp 14 can be heatable in the usual way.

Sowohl das Kammerunterteil 10 als auch das Kammerunterteil 11 können mit einem bodenseitigen Auslaß 22 versehen sein, um den gesamten Innenraum der jeweiligen Arbeitskammer 7, 8 zu evakuieren oder mit Gas zu füllen.Both the lower chamber part 10 and the lower chamber part 11 can be provided with a bottom-side outlet 22 in order to evacuate the entire interior of the respective working chamber 7, 8 or to fill it with gas.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, es ist vielmehr auch möglich, in dem zweiten Arbeitsbereich 6 zwei Schlitzdüsen zu verwenden, welche jeweils seitlich angeordnet sein können, wobei eine Schlitzdüse mit der Vakuumquelle verbunden ist, während die andere Schlitzdüse zur Zufuhr des Inertgases dient.The invention is not limited to the exemplary embodiment shown, but it is also possible to use two slot nozzles in the second working area 6, which can each be arranged laterally, one slot nozzle being connected to the vacuum source and the other slot nozzle for supplying the inert gas serves.
