Abstract

A mobile vacuum wrapping unit extracts air from a plastic bag containing perishable or sterile goods, which is subsequently heat sealed. The novelty is that all aspects of the unit including the vacuum pump (3) are powered by a 12 V source driven through a transformer supplied from the public electricity supply. The bag and contents are first held within a chamber (1) in which an initial vacuum is generated, and which is later used to support the subsequent vacuum packing process. The vacuum pump (3) is a membrane pump.

Description

Die Erfindung betrifft ein Vakuumverpackungsgerät für kleine und mittelgroße Produkte, bevorzugt Lebensmittel wie Fleisch, Wurst, Käse u. a.; aber auch andere Verpackungsanforderungen, wie z. B. bei medizinischen Einzweckgeräten, die steril bleiben müssen, oder bei hochwertigen technischen Artikeln, die vor Oxydation oder Verunreinigung zu schützen sind, können vorteil­ haft erfüllt werden. Herausragendes Anwendungsgebiet ist der erstmals unkompliziert mögliche Einsatz eines Vakuumverpackungsgerätes in den Bereichen Yachting und Camping sowie der Betrieb im Auto, z. B. für Jäger und Angler, und in medizinischen Fahrzeugen.The invention relates to a vacuum packaging device for small and medium-sized products, preferably food such as meat, sausage, cheese and. a .; but also others Packaging requirements such as B. in medical Single-purpose devices that must remain sterile, or at high quality technical articles that prevent oxidation or to protect against contamination can be an advantage be fulfilled. Outstanding area of application is the first uncomplicated possible use of a Vacuum packaging device in the fields of yachting and Camping as well as operation in the car, e.g. B. for hunters and Anglers, and in medical vehicles.

Vakuum-Einschweißgeräte in den bislang üblichen Anwendungsbereichen sind überwiegend Kammermaschinen, deren Basiselement eine sich öffnende und schließende Kammer ist, in die ein oder mehrere mit Produkten gefüllte Folienbeutel gelegt werden. Eine eingebaute Vakuumpumpe erzeugt in der Kammer und innerhalb des Beutels ein Vakuum und entzieht so auch dem Produkt den Sauerstoff. Danach erfolgt unter Einwirkung von Hitze und Druck die hermetisch dichte Versiegelung des Beutels.Vacuum welding devices in the usual way Areas of application are predominantly chamber machines, whose basic element is an opening and closing Chamber is in the one or more with products filled foil bags are placed. A built-in Vacuum pump generated in the chamber and inside the Bag a vacuum and thus also removes the product Oxygen. This is followed by exposure to heat and pressure the hermetically sealed seal of the Bag.

Alle bekannten Vakuumverpackungsgeräte arbeiten, damit das angestrebte Vakuum schnell und sicher erreicht wird, mit leistungsstarken Vakuumpumpen, die ent­ sprechende elektrische Anschlüsse benötigen. Beim derzeitigen Stand der Technik erfordern Hochvakuum- Einschweißgeräte deshalb ausnahmslos 110 V, 220 V oder 380 V Betriebsspannung. Der Strom für die Steuerung und Regeleinheit der Geräte muß folglich vom Hoch- in den Niederspannungsbereich transformiert werden. Die von der Pumpe und dem Transformator erzeugte erhebliche Wärmemenge wird über Ventilationssysteme und/oder mittels einer großräumig bemessenen Gehäusekonstruk­ tion abgeleitet. Die kompakten Baugruppen der Kammer­ maschinen führen dazu, daß selbst ihre kleinsten Ausführungen, obgleich häufig über Rollen fahrbar, grundsätzlich nur an einem Ort eingesetzt werden können.All known vacuum packaging devices work with it the desired vacuum is reached quickly and safely with powerful vacuum pumps that ent need talking electrical connections. At the  current state of the art require high vacuum Therefore, welding machines without exception 110 V, 220 V or 380 V operating voltage. The electricity for control and The control unit of the devices must therefore move from high to high Low voltage range to be transformed. The of the pump and the transformer generated considerable Heat quantity is via ventilation systems and / or by means of a spacious housing construction tion derived. The compact components of the chamber machines cause even the smallest Versions, although often wheeled, basically only be used in one place can.

Mobile Geräte, die es dem Verbraucher erlauben, zu Hause ein Vakuum von industrieller Qualität zu erzeugen, sind in jüngerer Zeit in vielfältigen Ausführungen bekannt geworden. Bei diesen Systemen wird die Luft nur aus dem das zu vakuumierende Gut beinhaltenden Beutel, der sich bis auf seine Öffnung außerhalb des Gerätes befindet, gesaugt. Durch den Wegfall der Vakuumierungskammer können die Geräte wesentlich kleiner und leichter gebaut werden; ihre Anwendung, namentlich das Betreiben der Kolbenpumpen, erfordert aber gleichfalls mindestens 110 V Betriebs­ spannung, was ihren Einsatz üblicherweise nach wie vor auf Orte in der Nähe fester Anschlüsse beschränkt.Mobile devices that allow the consumer to A vacuum of industrial quality at home produce are more recent in diverse Executions become known. With these systems the air is only made up of the good to be vacuumed containing pouch that extends to its opening located outside the device. By the The devices can dispense with the vacuum chamber be built much smaller and lighter; your Application, namely the operation of the piston pumps, but also requires at least 110 V operation voltage, what their use is usually still limited to locations near fixed connections.

Es ist daher Ziel und Aufgabe der Erfindung, ein mobiles Vakuum-Einschweißgerät vorzuschlagen, das sich gegenüber dem Stand der Technik durch erheblich erweiterte potentielle Anwendungsmöglichkeiten bei gleichzeitig weiter verbesserten Gebrauchseigenschaf­ ten, besonders Miniaturisierung und Verringerung der Masse, auszeichnet. It is therefore the aim and object of the invention to propose a mobile vacuum welding device that is compared to the prior art by considerably expanded potential applications in at the same time further improved utility property especially miniaturization and reduction of Mass, distinguished.  

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß alle Gerätefunktionen, also auch die der vakuumierenden Einheit, durch eine 12 V-Stromquelle betrieben werden. Dabei kann das Gerät auch mittels eines externen Transformators über das konventionelle Stromnetz gespeist werden; die 12 V-Stromversorgung erfolgt über Adapter. Es ist erfindungswesentlich, daß die Vakuum­ pumpe, wenn sie nicht für den eigentlichen Vakuumie­ rungsvorgang benötigt wird, in einer Unterdruckkapsel ein Vorvakuum erzeugt, welches dort gespeichert und bei Bedarf abgerufen wird. Damit wird die Zeitspanne, die erforderlich ist, um das gewünschte Vakuum im Folien­ beutel oder einem anderen Hohlkörper zu erreichen, wesentlich verkürzt. Daraus folgend kann der Leistungs­ bereich der Vakuumpumpe bzw. - bei Eingangsbetrieb über Hochspannung - der des Transformators vergleichsweise gering gehalten werden, was eine nachhaltige Miniaturi­ sierung dieser Bauteile erlaubt.According to the invention this object is achieved in that all device functions, including those of the vacuuming ones Unit operated by a 12 V power source. The device can also use an external device Transformers over the conventional electricity network be fed; the 12 V power supply is via Adapter. It is essential to the invention that the vacuum pump when not for the actual vacuumie is required in a vacuum capsule creates a backing vacuum, which is stored there and at Demand is retrieved. This will be the amount of time that is required to create the desired vacuum in the foils bag or another hollow body to reach significantly shortened. Hence the performance range of the vacuum pump or - in the case of input operation over High voltage - that of the transformer comparatively be kept low, which is a sustainable miniature Allocation of these components allowed.

Da alle Gerätefunktionen im Niederspannungsbereich und folglich mit nur geringer Wärmeentwicklung ablaufen, kann ein solches Gerät bei hohem Sicherheitsstandard sehr kompakt gebaut und erstmals wirklich mobil ein­ gesetzt werden. Die vergleichsweise geringen Material- und Montagekosten ermöglichen ein herausragendes Preis-/Leistungsverhältnis. Zudem zeichnet sich die erfindungsgemäße Entwicklung durch geringe Lärment­ wicklung aus. Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles näher erläutert; hierfür zeigt Fig. 1 den prinzipiellen Aufbau des Gerätes. Since all device functions in the low-voltage range and consequently with only low heat development, such a device can be built very compactly with a high security standard and can be used for the first time in a really mobile way. The comparatively low material and assembly costs enable an excellent price / performance ratio. In addition, the development according to the invention is characterized by a low level of noise. The invention is explained in more detail below using an exemplary embodiment; 1 this is shown in Fig. the basic structure of the device.

Bei ausgeschaltetem Gerät ist in der Unterdruckkapsel 1 ein Vorvakuum gespeichert; die Druckschalter A und B sind geschlossen. Will man einen Folienbeutel vakuu­ mieren, legt man diesen in die Vakuumkammer 2 und verschließt sie. Danach wird der Vakuumierungsvorgang gestartet - die Druckschalter A und B öffnen sich, gleichzeitig schaltet der Drucksensor 1 die Pumpe 3 ein und die Luft wird über die zentrale Unterdruckvertei­ lung 4 aus der Vakuumkammer 2 zur Unterdruckkapsel 1 und zur Pumpe 3 gezogen. Wenn die beiden Drucksensoren 1 und 11 den Ausgleich des Unterdruckes registrieren, wird der Druckschalter A geschlossen. Die Pumpe 3, eine Membranpumpe, arbeitet so lange, bis der gewünschte Unterdruck im Beutel erreicht ist. Der Drucksensor II schließt den Druckschalter B und öffnet den Druckschal­ ter A; parallel wird durch den Drucksensor II der Vorgang des Verschweißens des Beutels in bekannter Weise eingeleitet.When the device is switched off, a vacuum is stored in the vacuum capsule 1 ; pressure switches A and B are closed. If you want to vacuum a foil bag, put it in the vacuum chamber 2 and close it. Then the vacuuming process is started - the pressure switches A and B open, at the same time the pressure sensor 1 switches on the pump 3 and the air is drawn via the central vacuum distribution 4 from the vacuum chamber 2 to the vacuum capsule 1 and the pump 3 . When the two pressure sensors 1 and 11 register the compensation of the negative pressure, the pressure switch A is closed. The pump 3 , a diaphragm pump, works until the desired vacuum in the bag is reached. The pressure sensor II closes the pressure switch B and opens the pressure switch ter A; in parallel, the process of welding the bag is initiated in a known manner by the pressure sensor II.

In der Zwischenzeit speichert die Pumpe 3 ein Vakuum in der Unterdruckkapsel 1 bis ein neuer Beute 1 vakuumiert wird bzw. der Drucksensor 1 bei Erreichen des maximalen Unterdrucks in der Unterdruckkapsel 1 den Druckschalter A schließt und die Pumpe 3 abstellt. Somit befindet sich das mobile Vakuum-Einschweißgerät im Ausgangs­ zustand.In the meantime, the pump 3 stores a vacuum in the vacuum capsule 1 until a new prey 1 is vacuumed or the pressure sensor 1 closes the pressure switch A when the maximum vacuum in the vacuum capsule 1 is reached and the pump 3 is switched off. The mobile vacuum welding device is thus in the initial state.
