Description
Die Erfindung betrifft eine Vorrichtung zum gasdichten Verpacken von Gegenständen mit sich eng an die Gegenstände anlegendem Folienmaterial unter Einsatz eines Vakuums, vorzugsweise zum Durchführen des vorgenannten Verfahrens, umfassend eine Auflage für zumindest eine Schale und umfassend zumindest ein Siegelwerkzeug für die tiefziehbare Folie. Schließlich betrifft die Erfindung eine Verpackung.The invention relates to a device for the gas-tight packaging of articles with closely to the objects applying sheet material using a vacuum, preferably for carrying out the aforementioned method, comprising a support for at least one shell and comprising at least one sealing tool for the thermoformable film. Finally, the invention relates to a package.
Vorrichtungen der vorgenannten Gattungen werden dazu eingesetzt, Gegenstände zu verpacken. Bei diesen Gegenständen kann es sich um anorganische Produkte handeln, wie beispielsweise Werkzeuge oder Schreibwaren, welche in entsprechenden Verpackungen in Märkten zum Verkauf feilgehalten werden. Insbesondere dann, wenn ein Vakuum zum Tiefziehen der Folie, die mit der Schale verschweißt wird, eingesetzt wird, kann es sich bei den Gegenständen um organische Produkte, wie Lebensmittel handeln. Insbesondere Fleisch- und Wurstwaren werden mit dieser Art Verpackungen eingepackt, um im Innenraum der Verpackung ein möglichst geringes Gasvolumen zu belassen.Devices of the aforementioned types are used to package objects. These articles may be inorganic products, such as tools or stationery, which are held in suitable packaging for sale in markets. In particular, when a vacuum is used to deep-draw the film which is welded to the shell, the articles may be organic products, such as food. In particular, meat and sausage products are packed with this type of packaging in order to leave the smallest possible gas volume in the interior of the packaging.
Mit den bekannten Vorrichtungen wird so vorgegangen, dass ein Gegenstand in eine Schale eingelegt wird und anschließend die tiefziehbare Folie mit der Schale verschweißt wird. Nach dem Tiefziehen wird die Folie auf das Maß der Schale zugeschnitten, dabei erfolgt häufig ein Schneiden von Folie und Schale in einem Schritt, z. B. wenn ein Verrutschen der Schale eintritt. Auf nachteilige Weise können dabei scharfe Schalenränder ausgebildet werden. Ein weiterer Nachteil ist, dass dieses nachfolgende Schneiden an der noch für das Schweißen erwärmten Folie vorgenommen wird. Die Folie weist in ihrem erwärmten Zustand eine weiche Konsistenz auf, so dass sie einem Zuschneidemesser wenig Widerstand entgegensetzen kann. In der Folge entstehen unscharfe Schnittkanten, welche zu einem unansehnlichen Knautschen und Verwerfen der Schnittränder der Folie führen.With the known devices, the procedure is such that an object is placed in a dish and then the thermoformable film is welded to the shell. After deep drawing, the film is cut to the size of the shell, this is often done a cutting of foil and Shell in one step, z. B. when slipping of the shell occurs. In a disadvantageous way, sharp shell edges can be formed. Another disadvantage is that this subsequent cutting is done on the still heated for welding film. The film has a soft consistency in its heated state so that it can provide little resistance to a cutting knife. As a result, blurred cut edges, which lead to an unsightly creasing and discarding the cut edges of the film.

Mit der erfindungsgemäßen Vorrichtung ist vorgesehen, die Folie zunächst auf die Schale aufzubringen und anschließend zuzuschneiden. Aufgrund dessen ist nicht länger eine separate Schneidstation für die Folie erforderlich. Sie kann erfindungsgemäß der Vorrichtung zugeordnet sein, da das Schneiden der Folie unmittelbar nach dem Versiegeln bzw. Verschweißen der Folie erfolgt.With the device according to the invention it is provided to first apply the film to the shell and then to cut it. Because of this, a separate cutting station for the film is no longer required. It can be assigned to the device according to the invention, since the cutting of the film takes place immediately after the sealing or welding of the film.
Bei der erfindungsgemäßen Vorrichtung ist vorgesehen, dass zwischen den Schalen und der tiefziehbaren Folie eine Distanzplatte angeordnet ist, welche auf die Auflageeinrichtung für den umlaufenden Rand auflegbar ist, wobei dabei der umlaufende Rand zumindest abschnittsweise frei bleibt. Diese Distanzplatte unterstützt das Zuschneiden der tiefziehbaren Folie nach ihrem Aufschweißen bzw. Versiegeln auf den umlaufenden Rand der Schale. Dazu ist die Distanzplatte auf die in der Auflageeinrichtung aufgenommenen umlaufenden Ränder der Schale auflegbar. Die Distanzplatte bildet nun mit ihrer oben liegenden Oberfläche eine Ebene aus, die oberhalb des umlaufenden Randes angeordnet ist. Auf diese Ebene kann die tiefziehbare Folie aufgelegt werden, mit der Distanzplatte wird die tiefziehbare Folie gegen das Siegelwerkzeug geführt.In the device according to the invention it is provided that between the shells and the thermoformable film, a spacer plate is arranged, which is placed on the support means for the peripheral edge, wherein the peripheral edge remains at least partially free. This spacer plate helps to cut the thermoformable sheet after it has been welded or sealed onto the peripheral edge of the tray. For this purpose, the spacer plate can be placed on the recorded in the support means peripheral edges of the shell. The spacer plate now forms with its surface above a level, which is located above the peripheral edge. On this level, the thermoformable film can be placed, with the spacer plate, the thermoformable sheet is guided against the sealing tool.
An die tiefziehbare Folie kann vor ihrem Aufschweißen ein Vakuum angelegt werden, um sie zu dehnen. Mit der Distanzplatte wird die Folie gegen das Siegelwerkzeug geführt und festgehalten, wenn mit dem Siegelwerkzeug ein Vakuum an die Folie angelegt wird.A vacuum may be applied to the thermoformable sheet prior to welding to stretch it. With the spacer plate, the film is guided against the sealing tool and held when a vacuum is applied to the film with the sealing tool.
Das Siegelwerkzeug hat erfindungsgemäß eine nach innen gewölbte Ausbildung, in welche hinein sich die tiefziehbare Folie bei Anlegen des Vakuums ausdehnen kann. Die umlaufenden Ränder der Schale werden von der Distanzplatte frei gehalten. Auch die anderen Bereiche der Schale können frei bleiben, um eine großflächige Anlage des Siegelwerkzeuges zu ermöglichen, damit neben dem Verschweißen der tiefziehbaren Folie zugleich ein Erwärmen dieser Folie für einen nachfolgenden Tiefziehvorgang erfolgt. In der Distanzplatte ist dafür vorzugsweise zumindest ein mit dem Behälter in deckungsgleiche Lage bringbarer Durchbruch angeordnet. Dieser Durchbruch hat dann zum Siegelwerkzeug korrespondierende Abmessungen.The sealing tool according to the invention has an inwardly curved formation into which the deep-drawable film can expand when the vacuum is applied. The peripheral edges of the shell are kept free by the spacer plate. The other areas of the shell can remain free to allow a large-scale investment of the sealing tool, so that in addition to the welding of the thermoformable film at the same time a heating of this film for a subsequent deep-drawing process. In the Distance plate is preferably arranged at least one with the container in congruent position bringable breakthrough. This breakthrough then has dimensions corresponding to the sealing tool.
Die Schneideinrichtung umfasst vorzugsweise Messerklingen, mit denen ein Schneiden der tiefziehbaren Folie erfolgreich durchführbar ist.The cutting device preferably comprises knife blades, with which a cutting of the thermoformable film is successfully carried out.
Nach einer nächsten Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, dass die Schneideinrichtung dem Siegelwerkzeug räumlich zugeordnet ist. Durch diese räumliche Zuordnung kann ein zeitlich kurz aufeinander folgendes Versiegeln und Schneiden erfolgen. Die Zuordnung von Schneideinrichtung und Siegelwerkzeug zueinander ist räumlich gegeben, konstruktiv sind beide Baugruppen voneinander unabhängig, um ein separates Durchführen der Arbeitsgänge Versiegeln und Zuschneiden zu ermöglichen.According to a next development of the device according to the invention it is provided that the cutting device is spatially associated with the sealing tool. Due to this spatial assignment, a temporally short successive sealing and cutting can take place. The assignment of cutting device and sealing tool to each other is given spatially, structurally, both modules are independent of each other to allow a separate performing the operations sealing and cutting.
Die Schneideinrichtung kann das Siegelwerkzeug umlaufen. Ist das Siegelwerkzeug beispielsweise rechteckig ausgebildet, so können Messerklingen der Schneideinrichtung dieses Siegelwerkzeug wie einen Rahmen umlaufen. Nach dem Aufsetzen des Siegelwerkzeuges auf die Folie erfolgt mit den rahmenartig ausgebildeten Messerklingen ein Zuschneiden derselben.The cutting device can rotate the sealing tool. If the sealing tool is rectangular, for example, knife blades of the cutting device can circulate this sealing tool like a frame. After placing the sealing tool on the film is done with the frame-like knife blades cutting the same.
Zur konstruktiven Ausbildung der Vorrichtung sieht eine Weiterbildung der Erfindung vor, dass die Auflage für die Schale und/oder das Siegelwerkzeug höhenveränderbar geführt sind. Auflage und Siegelwerkzeug können somit einander angenähert und voneinander entfernt werden. Die Annäherung wird dazu genutzt, das Siegelwerkzeug auf die tiefziehbare Folie aufzulegen, wenn das Schneidwerkzeug vom umlaufenden Rand der Schale noch einen Abstand einhält.For structural design of the device, a development of the invention provides that the support for the shell and / or the sealing tool are guided vertically variable. Pad and sealing tool can thus be approximated and removed from each other. The approach is used to place the sealing tool on the thermoformable sheet when the cutting tool still maintains a distance from the peripheral edge of the tray.
Eine nächste Weiterbildung der Erfindung sieht vor, dass die Auflage zumindest eine Auflageeinrichtung für den umlaufenden Rand der Schale aufweist. Die Schale ist mit Hilfe der Auflage in die Auflageeinrichtung für den umlaufenden Rand einbringbar. Der umlaufende Rand wird vorzugsweise auf diese Auflageeinrichtung aufgelegt, damit er für das Verschweißen bzw. Versiegeln mit der tiefziehbaren Folie bereitliegt. Die Auflageeinrichtung unterstützt den umlaufenden Rand und bildet ein Gegenlager für das auf den Rand aufzulegende Siegelwerkzeug aus.A next development of the invention provides that the support at least one support means for the peripheral edge of the shell having. The shell can be introduced by means of the support in the support device for the peripheral edge. The peripheral edge is preferably placed on this support means so that it is ready for welding or sealing with the thermoformable film. The support device supports the peripheral edge and forms an abutment for the aufgelegende on the edge sealing tool.
Bei dem Einsatz der Distanzplatte mit den Durchbrüchen ist es vorteilhaft, dem Siegelwerkzeug die Schneideinrichtung räumlich zuzuordnen. Bei einem Heranführen des Siegelwerkzeuges an die tiefziehbare Folie kann zugleich ein Zuführen der Schneideinrichtung erfolgen. Die Schneideinrichtung ist dabei vorzugsweise wie das Siegelwerkzeug durch den Durchbruch der Distanzplatte hindurch führbar. Das Schneidwerkzeug ist dabei vorzugsweise vom Siegelwerkzeug abgekoppelt und federnd gelagert. Durch diese Abkopplung ist es ermöglicht, das Siegelwerkzeug zunächst näher an die Schale heranzuführen als das Schneidwerkzeug. Nach dieser Heranführung des Siegelwerkzeuges kann eine Versiegelung zwischen Folie und Schale erfolge Folie eingesetzt wird. Dazu wird das Schneidwerkzeug in einer entsprechenden Führung bis in die Ebene der Oberfläche des umlaufenden Randes geführt. Die auf dem umlaufenden Rand aufliegende tiefziehbare Folie wird geschnitten, das Messer wird dabei aber nicht bis in den umlaufenden Rand hinein bewegt. Der umlaufende Rand bleibt unversehrt.When using the spacer plate with the apertures, it is advantageous to assign the cutting device spatially to the sealing tool. When the sealing tool is brought to the deep-drawable film, the cutting device can be fed at the same time. The cutting device is preferably like the sealing tool through the breakthrough of the spacer plate feasible. The cutting tool is preferably uncoupled from the sealing tool and resiliently mounted. This decoupling makes it possible to bring the sealing tool closer to the shell first than the cutting tool. After this approach of the sealing tool, a seal between the film and shell success foil is used. For this purpose, the cutting tool is guided in a corresponding guide to the plane of the surface of the peripheral edge. The lying on the peripheral edge thermoformable film is cut, but the knife is not moved into the peripheral edge. The peripheral edge remains intact.
Zur weiteren Ausbildung der erfindungsgemäßen Vorrichtung ist noch vorzugsweise vorgesehen, dass durch das Siegelwerkzeug hindurch zumindest eine Überdruckleitung und/oder eine Vakuumleitung verläuft. Das Siegelwerkzeug ist auf der Seite der tiefziehbaren Folie angeordnet, welche der Schale abgekehrt ist. Durch die durch das Siegelwerkzeug hindurch verlaufende Überdruckleitung kann ein Überdruckmedium, z. B. Luft, hinzugefügt werden, um auf dieser Seite der Folie den verfahrensgemäß vorzugsweise vorgesehenen Überdruck zu erzeugen. Über die Vakuumleitung wird der verfahrungsgemäß vorgesehene Unterdruck erzeugt.For a further embodiment of the device according to the invention, it is preferably provided that at least one overpressure line and / or one vacuum line runs through the sealing tool. The sealing tool is disposed on the side of the thermoformable sheet, which is turned away from the shell. By passing through the sealing tool through pressure line, an overpressure medium, for.
