Description

Die vorliegende Erfindung betrifft eine Verpackungsmaschine mit einer Tiefziehstation, in der plane Kunststofffolien mit Unter- oder Überdruck beaufschlagbar sind, wobei der Unter- und der Überdruck mit demselben Mittel erzeugbar sind.The The present invention relates to a packaging machine with a Thermoforming station, in the flat plastic films with low or high pressure can be acted upon, the underpressure and the overpressure with the same means can be generated.

Bei Verpackungsmaschinen, insbesondere bei sogenannten Form-Füll-Siegel-Maschinen werden Mulden in plane Kunststofffolien, insbesondere durch Tiefziehen, eingeformt, nachdem diese vorher erwärmt wurden. Dieses Tiefziehen erfolgt in sogenannten Tiefziehstationen, in denen es oftmals nötig ist, die Kunststofffolie sowohl mit einem Unter- als auch mit einem Überdruck zu beaufschlagen. Dafür wurden bisher zwei getrennte Druckmittel benötigt, was diese Tiefziehstationen vergleichsweise teuer und deren Wartung aufwändig macht.at Packaging machines, especially in so-called form-fill-seal machines Depressions in flat plastic films, in particular by deep-drawing, formed after they were previously heated. This thermoforming takes place in so-called thermoforming stations, where it is often necessary the plastic film with both a low and a positive pressure to act on. For that were previously required two separate pressure medium, what these thermoforming stations comparatively expensive and expensive to maintain.

Es war deshalb die Aufgabe der vorliegenden Erfindung, eine Verpackungsmaschine zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist.It Therefore, the object of the present invention was a packaging machine to disposal to provide that does not have the disadvantages of the prior art.

Gelöst wird die Aufgabe mit einer Verpackungsmaschine mit einer Tiefziehstation, in der plane Kunststofffolien mit Unter- oder Überdruck beaufschlagbar sind, wobei der Unter- und der Überdruck mit demselben Mittel erzeugbar ist.Is solved the task with a packaging machine with a thermoforming station, can be acted upon in the planar plastic films with negative or positive pressure, where the underpressure and the overpressure with the same means can be produced.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass die erfindungsgemäße Verpackungsmaschine einfach und kostengünstig herzustellen ist. Durch die vorgenannte Erfindung sind erhebliche Kosteneinsparungen möglich.It was for the expert very much amazing and not to be expected that the packaging machine according to the invention simple and inexpensive to produce is. By the aforementioned invention are significant cost savings possible.

Erfindungsgemäß weist die Verpackungsmaschine eine Tiefziehstation auf, in der eine Verpackungsfolie sowohl mit Unter- als auch mit Überdruck beaufschlagbar ist. Erfindungsgemäß wird der jeweilige Druck mit demselben Mittel erzeugt.According to the invention the packaging machine on a thermoforming station, in which a packaging film can be acted upon with both low and with overpressure is. According to the invention respective pressure generated with the same agent.

Vorzugsweise weist die Tiefziehstation ein Ober- und ein Unterwerkzeug auf, wobei das Oberwerkzeug oberhalb der Kunststofffolie und das Unterwerkzeug unterhalb der Kunststofffolie angeordnet ist.Preferably the thermoforming station has an upper and a lower tool, wherein the upper tool above the plastic film and the lower tool is arranged below the plastic film.

Vorzugsweise werden der Unterdruck oder der Überdruck im Bereich des Unterwerkzeugs oder des Oberwerkzeugs erzeugt. Vorzugsweise wird mit Unter- und/oder Überdruck die Folie gegen die Heizplatte gedrückt, so dass der Wärmeübergang zwischen der Kunststofffolie und dem Heizmittel verbessert wird. Dadurch kann die Kunststofffolie wesentlich besser und schneller erwärmt werden, um sie sodann zu einer Verpackungsmulde tiefzuziehen. Das Tiefziehen erfolgt ebenfalls mit Unter- und/oder Überdruck.Preferably will be the negative pressure or the overpressure generated in the area of the lower tool or the upper tool. Preferably is with under and / or over pressure pressed the foil against the heating plate, so that the heat transfer between the plastic film and the heating means is improved. This allows the plastic film much better and faster heated then deep-drawn to a packaging tray. The Deep drawing also takes place with underpressure and / or overpressure.

Bei dem Mittel zur Erzeugung des Unter- bzw. des Überdrucks kann es sich um jedes dem Fachmann geläufige Mittel handeln, mit dem sowohl Über- als auch Unterdruck erzeugbar ist. Vorzugsweise handelt es sich jedoch um eine Pumpe, ganz besonders bevorzugt um eine Klauen- Vakuumpumpe. Bei derartigen Pumpen drehen sich zwei Klauen gegensinnig in einem Gehäuse. Durch die spezielle geometrische Form der Klauen wird angesaugte Luft im Inneren der Vakuumpumpe verdichtet. Die Luft wird über den Saugflansch angesaugt, im Verdichtungsraum verdichtet und auf der Druckseite anschließend wieder ausgestoßen.at the means for generating the underpressure or the overpressure may be any the person skilled in the art Act by which both as well as negative pressure can be generated. It is preferable but a pump, most preferably a claw vacuum pump. In such pumps, two jaws rotate in opposite directions in one Casing. Due to the special geometric shape of the claws is sucked Compressed air inside the vacuum pump. The air is over the Sucked suction flange, compressed in the compression chamber and on the Printing side afterwards ejected again.

Vorzugsweise ist die Pumpe an einen oder mehrere Behälter angeschlossen, in denen Unter- oder Überdruck herrscht. Diese Behälter dienen als Pufferbehälter.Preferably the pump is connected to one or more tanks in which Under or over pressure prevails. These containers serve as buffer tanks.

Im folgenden wird die Erfindung anhand der einzigen Figur erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein.in the Following, the invention will be explained with reference to the single figure. These Explanations are merely exemplary and limit the general inventive concept not a.

1 zeigt schematisch die Tiefziehstation einer Verpackungsmaschine. In dieser Tiefziehstation wird in eine plane Kunststofffolie 1 eine oder mehrere Verpackungsmulde(n), beispielsweise durch Tiefziehen, eingeformt. Die Tiefziehstation weist ein Oberwerkzeug 3 und ein Unterwerkzeug 2 auf. Zumindest das Unterwerkzeug ist vertikal beweglich angeordnet. In dem Unterwerkzeug befindet sich das Negativ der herzustellenden Verpackungsmulde. In dem Oberwerkzeug ist in dem vorliegenden Fall ein Heizelement 4 angeordnet, um die Kunststofffolie vor dem Verformen bis zur Plastifizierungstemperatur aufzuwärmen. Der Fachmann versteht, dass das Heizelement auch vor der Tiefziehstation angeordnet sein kann. Im Bereich des Unterwerkzeuges ist eine Klauen-Vakuumpumpe, beispielsweise der Firma Busch, DE-79689 Maulberg, angeordnet, mit der sowohl Unterdruck als auch Überdruck in einem Überdruckbehalter 8 oder Unterdruck in einem Unterdruckbehälter 9 erzeugt werden kann. Dafür werden entweder das Ventil 15 oder das Ventil 10 geöffnet. Der Bereich, in dem Unterdruck herrscht ist mit 5 und der Bereich in dem Überdruck herrscht mit 7 gekennzeichnet. Sowohl der Unterdruckbehälter 9 als auch der Überdruckbehälter 8 sind mit dem Oberwerkzeug 3 und mit dem Unterwerkzeug 2 verbunden, wobei der jeweilige Druck in der Regel nur in einem der beiden Werkzeuge anliegen wird, d.h. entweder Unterdruck oder Überdruck im Unter- bzw. im Oberwerkzeug anliegt. Dementsprechend ist immer nur eines der Ventile 13, 14 bzw. 11, 12 geöffnet. Es ist jedoch durchaus vorteilhaft, wenn in dem einen Werkzeug Überdruck und in dem anderen Werkzeug Unterdruck herrscht und umgekehrt. Der Fachmann erkennt, dass die Behälter 8, 9 nur optional sind und als Pufferbehälter dienen, so dass bei Bedarf bzw. beim Öffnen des jeweiligen Ventils die entsprechenden Drücke im wesentlichen sofort zur Verfügung stehen. Dadurch wird das Anliegen des jeweiligen Drucks beschleunigt bzw. es steht gleichzeitig sowohl Über- als auch Unterdruck zur Verfügung. Der Überdruck bzw. Unterdruck ist jeweils bezogen auf Atmosphärendruck zu verstehen. 1 shows schematically the thermoforming station of a packaging machine. In this thermoforming station is in a flat plastic film 1 one or more packaging tray (s), for example by deep drawing molded. The thermoforming station has an upper tool 3 and a lower tool 2 on. At least the lower tool is arranged vertically movable. In the lower tool is the negative of the packaging tray to be produced. In the upper tool in the present case is a heating element 4 arranged to heat the plastic film before deformation to the plasticizing temperature. The skilled person understands that the heating element can also be arranged in front of the thermoforming station. In the area of the lower tool, a claw vacuum pump, for example, the company Busch, DE-79689 Maulberg, arranged with the both negative pressure and pressure in a Überdruckbehalter 8th or negative pressure in a vacuum tank 9 can be generated. This will either be the valve 15 or the valve 10 open. The area in which there is negative pressure is with 5 and the area in the overpressure prevails 7 characterized. Both the vacuum tank 9 as well as the pressure vessel 8th are with the upper tool 3 and with the lower tool 2 connected, wherein the respective pressure is usually present only in one of the two tools, ie either negative or positive pressure in the lower or in the upper tool is present. Accordingly, only one of the valves is always 13 . 14 respectively. 11 . 12 open. However, it is quite advantageous if negative pressure prevails in one tool and negative pressure in the other tool and vice versa. The skilled artisan will recognize that the containers 8th . 9 are only optional and serve as a buffer container, so that when needed or at Opening the respective valve, the corresponding pressures are available substantially immediately. As a result, the concern of the respective pressure is accelerated or it is simultaneously both positive and negative pressure available. The overpressure or vacuum is to be understood in each case based on atmospheric pressure.

In der Regel wird zu Beginn der Verformung in dem Unterwerkzeug zunächst ein Überdruck und/oder in dem Oberwerkzeug ein Unterdruck erzeugt. Mittels dieser Druckverhältnisse wird die Kunststofffolie 1 gegen das Heizmittel 4 gedrückt, um den Wärmeübergang zwischen der Kunststofffolie 1 und dem Heizmittel 4 zu verbessern. Sobald die Kunststofffolie ihre Plastifizierungstemperatur erreicht hat, wird mittels der Pumpe 6 oder mit den Druckbehaltern 8, 9 in dem Unterwerkzeug 2 ein Unterdruck erzeugt und/oder in dem Oberwerkzeug ein Überdruck erzeugt, mit dem die Kunststofffolie sodann verformt wird.As a rule, an overpressure and / or a negative pressure is generated in the upper tool at the beginning of the deformation in the lower tool. By means of these pressure conditions, the plastic film 1 against the heating medium 4 pressed the heat transfer between the plastic film 1 and the heating means 4 to improve. As soon as the plastic film has reached its plasticizing temperature, the pump is used 6 or with the pressure vessels 8th . 9 in the lower tool 2 generates a negative pressure and / or generates an overpressure in the upper tool, with which the plastic film is then deformed.

Die vorliegende Erfindung hat den Vorteil, dass mit der Pumpe 6 sowohl der benötigte Unter- als auch der benötigte Überdruck erzeugbar sind.The present invention has the advantage that with the pump 6 Both the required lower and the required pressure can be generated.
