Abstract

A filling system for bottles and other containers which minimises the contact between residual gas in the containers and the liquid has a venting pipe (11) concentric to the filling system and extending from inside the neck of the container to an upper outlet inside a venting duct (13) above the liquid reservoir. The reservoir is ring shaped and serves a number of similar filling positions. The reservoir and the venting duct are connected to an exhaust system with one or more vacuum pumps. Control valves (15, 16) regulate the venting process. The venting pipe passes into the venting duct via an aperture (17) sufficiently wide to permit a limited amount of pressure compensation.

Description

Die vorliegende Erfindung betrifft eine Füllmaschine gemäß des Oberbegriffes des Anspruches 1. Vorteilhaft Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The present invention relates to a filling machine according to the preamble of Claim 1. Advantageous developments of the invention are in the dependent claims specified.

Bei Füllmaschinen zur Befüllung von Behältern wie z.B. Flaschen, Dosen, Kanistern oder dergleichen, ist es seit geraumer Zeit bekannt, die zu befüllenden Behälter vor dem Befüllen zunächst mit Vakuum und einem Inertgas wie z.B. CO2 oder Dampf zu behandeln. Durch dieses so genannte Spülen sollen Keimbelastung und Sauerstoffgehalt in den Behältern gesenkt werden.In filling machines for filling containers such as bottles, cans, canisters or the like, it has been known for some time to first treat the containers to be filled with a vacuum and an inert gas such as CO 2 or steam before filling. This so-called rinsing is intended to reduce bacterial load and oxygen content in the containers.

Diese Vorgehensweise ist aus Gründen der Hygiene und der Haltbarkeit insbesondere bei der Abfüllung von bakteriologisch kritischen und/oder sauerstoffempfindlichen Füllgütern üblich. Die dabei aus den Behältern zu entfernenden Gase werden in der Regel durch separate Gaswege oder -kanäle abgeführt.This procedure is for reasons of hygiene and durability in particular in the filling of bacteriologically critical and / or oxygen-sensitive Fillings usual. The thereby to be removed from the containers gases are in the Usually dissipated by separate gas paths or channels.

Neben der Verwendung von separaten Gaswegen oder -kanälen sind auch Ausgestaltungen bekannt geworden, bei denen die Gasabfuhr aus den Behältern anhand eines so genannten Rückgasrohres erfolgt.In addition to the use of separate gas paths or channels are also embodiments have become known in which the gas removal from the containers based a so-called return gas pipe takes place.

Diese Rückgasrohre, welche bei zahlreichen Ausgestaltungen von Füllmaschinen ebenfalls dazu verwendet werden, das während des Füllvorganges aus dem zu füllenden Behälter entweichende Gas abzuführen, sind in der Regel in den Speicherbehälter für das abzufüllende Füllgut geführt, wo sie oberhalb des dortigen Flüssigkeitsspiegels enden.These return gas tubes, which in many embodiments of filling machines also be used to, during the filling of the to be filled Discharge gas escaping gas are usually in the storage tank led for the contents to be filled, where they are above the local liquid level end up.

Bei derartigen Ausgestaltungen, bei denen Umgebungsluft, zumindest aber mit dem Behälter in Kontakt gekommenes Spülgas direkt mit dem Füllgut in Berührung kommt, ist zwangsläufig ein erhöhtes Risiko der Kontamination des Füllgutes gegeben. Dieses Risiko ist insbesondere dann groß, wenn Rückgas und Füllgut große gemeinsame Kontaktflächen aufweisen.In such embodiments in which ambient air, but at least with the Container in contact flushing gas directly in contact with the contents inevitably there is an increased risk of contamination of the contents. This risk is particularly great when return gas and product large have common contact surfaces.

Aus der DE 37 31 759 ist es bekannt, an der Umfangsfläche eines Ringkessels mehrere, separate Füllorgane anzuordnen, welche ein bestimmtes Flüssigkeitsvolumen für die Aufnahme von Füllgut und einen über dem Füllgut befindlichen Gasraum aufweisen. Dabei ist vorgesehen, dass das jeweilige Rückgasrohr innerhalb dieses separaten Füllorgans endet. Zwar tritt das Rückgas bei dieser Ausgestaltung zunächst nur mit dem im Füllorgan selbst befindlichen Füllgutvolumen in direkten Kontakt, wodurch das Kontaminationsrisiko reduziert wird, doch ist eine schwerwiegende Kontamination des Füllgutes nicht gänzlich ausgeschlossen, da das Rückgas aus jedem Füllorgan durch eine Durchgangsöffnung mit großem Durchmesser in den Ringkessel gelangen kann.From DE 37 31 759 it is known, on the peripheral surface of a ring boiler several, to arrange separate Füllorgane which a certain volume of liquid have for receiving contents and a gas space located above the contents. It is provided that the respective return gas pipe within this separate Filler ends. Although the return gas occurs in this embodiment initially only in direct contact with the filling material volume located in the filling element itself, whereby the risk of contamination is reduced, but is a serious contamination the contents are not completely excluded, since the return gas from each Filling member through a passage opening with a large diameter in the ring bowl can get.

In der DE 39 28 009 wurde eine Füllmaschine mit einem separaten, oberhalb des Speicherbehälters angeordneten Rückgaskanal vorgestellt. Bei dieser Vorrichtung wird das Rückgas über ein zusätzliches Wechselventil entweder in den Speicherbehälter für das abzufüllende Füllgut oder aber in den Rückgaskanal geleitet. Ebenfalls ist bei der DE 39 28 009 vorgesehen, den Druck im Rückgaskanal niedriger als den Druck im Speicherbehälter einzustellen. Aufgrund des vorgesehenen Wechselventils und der unterschiedlichen Soll-Drücke ist eine derartige Vorrichtung mechanisch aufwändig und in der Herstellung teuer.In DE 39 28 009 a filling machine with a separate, above the Storage tank arranged return gas channel presented. In this device is the return gas via an additional shuttle valve either in the storage tank for the contents to be filled or passed into the return gas channel. Also is provided in DE 39 28 009, the pressure in the return gas channel lower than the Adjust pressure in storage tank. Due to the provided shuttle valve and the different desired pressures, such a device is mechanical consuming and expensive to manufacture.

Aufgabe und Ziel der vorliegenden Erfindung ist es, die oben dargestellten Nachteile zu vermeiden. Dazu stellt die Erfindung eine Füllmaschine vor bei welcher ein Rückgasrohr unmittelbar in einem separaten Rückgaskanal endet, wobei dieser durch eine Öffnung kleiner Querschnittsfläche mit dem Speicherbehälter verbunden ist, und Rückgaskanal und Speicherbehälter mit einer gemeinsamen Unterdruck- bzw. Vakuumquelle verbunden sind und im Wesentlichen den selben Druck aufweisen.The object and purpose of the present invention is to overcome the disadvantages presented above to avoid. For this purpose, the invention provides a filling machine in which a return gas pipe immediately ends in a separate return gas channel, this one by a Opening of small cross-sectional area is connected to the storage container, and Return gas channel and storage tank with a common vacuum or vacuum source are connected and have substantially the same pressure.

Im Nachfolgenden wird die vorliegende Erfindung anhand eines Ausführungsbeispieles näher erläutert.In the following, the present invention will be described with reference to an embodiment explained in more detail.

Im Einzelnen zeigt die

In detail, the shows
FIG. 1:
in a simplified and partial illustration of a filling machine according to the invention.

Weiterbildungen, Vorteile und Anwendungsmöglichkeiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen und der Zeichnung. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger Kombination den Gegenstand der Erfindung, unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung. Gleichzeitig wird der Inhalt der Ansprüche zu einem Bestandteil der Beschreibung gemacht.Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and the drawing. In this case, all described and / or illustrated features form for themselves or in any combination, the subject matter of the invention, independently of its Summary in the claims or their dependency. At the same time the content of the claims has become part of the description.

Bei dem in der Figur 1 dargestellten Ausführungsbeispiel handelt es sich um eine Füllmaschine umlaufender Bauart mit mehreren, an ihrem Umfang angeordneten Füllstationen. Jeder dieser Füllstationen sind u.a. ein Zentrierelement, ein Flüssigkeitsventil und ein Rückgasrohr 11 zugeordnet. Diese Rückgasrohr 11 ist im Zentrum des Flüssigkeitsventils angeordnet, und erstreckt sich vom Inneren der Behältermündung bis in den Rückgaskanal 13, wobei es den Speicherbehälter für das abzufüllende Füllgut 12 vollständig durchdringt.In the embodiment shown in the figure 1 is a Filling machine of rotating design with several, arranged at its periphery Filling stations. Each of these filling stations are u.a. a centering element, a liquid valve and a return gas pipe 11 assigned. This return gas pipe 11 is in the center the liquid valve disposed, and extends from the interior of the container mouth into the return gas channel 13, wherein it is the storage container for the to be filled Full contents 12 penetrates completely.

Der Rückgaskanal 13 ist oberhalb des Speicherbehälters 12 angeordnet, und ist vorteilhafter Weise als umlaufender, vollständig geschlossener Ringkanal ausgebildet.The return gas channel 13 is arranged above the storage container 12, and is formed advantageously as a circumferential, completely closed annular channel.

Rückgaskanal 13 und Speicherbehälter 12 sind an eine gemeinsame Unterdruckoder Vakuumquelle 15 angeschlossen, wobei der Anschluss des Speicherbehälters 12 unter Verwendung eines steuer- oder regelbaren Gasstromventils 16 erfolgt.Return gas channel 13 and storage tank 12 are connected to a common negative pressure or Vacuum source 15 is connected, wherein the connection of the storage container 12 using a controllable or controllable gas flow valve 16 is carried out.

In einer weiteren, ebenfalls vorteilhaften Ausbildung der vorliegenden Erfindung ist vorgesehen, Rückgaskanal 13 und Speicherbehälter 12 jeweils mit einer eigenen Vakuum- oder Unterdruckquelle 15 auszustatten.In a further, likewise advantageous embodiment of the present invention provided, return gas channel 13 and storage tank 12 each with its own Equip vacuum or vacuum source 15.

Um die Durchführung des Rückgasrohres 11 durch den Deckel des Speicherbehälters 12 zu ermöglichen, ist in diesem je Rückgasrohr 11 eine, auf den Durchmesser des Rückgasrohres 11 abgestimmte Bohrung 17 vorgesehen. Die Abstimmung der Durchmesser von Rückgasrohr 11 und Bohrung 17 erfolgt vorzugsweise derart, dass sich als Verbindung zwischen Rückgaskanal 13 und Speicherbehälter 12 lediglich eine kreisringförmige Fläche geringen Flächeninhaltes ausbildet, wodurch die Kontaktmöglichkeiten zwischen Rückgas und Füllgut und somit auch das Kontaminationsrisiko deutlich reduziert werden.To the implementation of the return gas pipe 11 through the lid of the storage container 12 to allow in this ever return gas pipe 11 a, to the diameter the return gas pipe 11 tuned bore 17 is provided. The vote of the Diameter of return gas pipe 11 and bore 17 is preferably such that itself as a connection between return gas channel 13 and storage tank 12 only forms an annular surface of small surface area, whereby the contact possibilities between return gas and filling material and thus also the risk of contamination be significantly reduced.

Als besonders vorteilhaft haben sich Ausgestaltungen erwiesen, bei denen der Flächeninhalt der kreisringförmigen Fläche kleiner als 100 mm2 ist.Be particularly advantageous embodiments have proven in which the surface area of the annular surface is smaller than 100 mm 2 .

Um unnötige, nicht zwingend durch den Füllprozess bedingte Gaseinbringungen in Speicherbehälter 12 und/oder Rückgaskanal 13 zu vermeiden, ist in Rahmen der vorliegenden Erfindung vorgesehen, Mittel zu verwenden, welche es gestatten, das obere Ende des Rückgasrohres 11 bei Bedarf sicher zu verschließen. Bei diesen Mitteln kann es sich - wie exemplarisch dargestellt - z.B. um durch einen Pneumatikzylinder 19 betätigte Membranverschlüsse18 oder ebenso betätigte Stößel, Kolben oder andere geeignete Dichtelemente handeln.To unnecessary, not necessarily due to the filling process gas injections in Storage tank 12 and / or return gas channel 13 to avoid is in the context of present invention to use means which allow the safely close the upper end of the return gas pipe 11 if necessary. In these It may be - as exemplified - e.g. around by a pneumatic cylinder 19 actuated membrane closures18 or similarly actuated plungers, pistons or other suitable sealing elements.

Hinsichtlich der Ansteuerung dieser, z.B. pneumatisch betätigten Mittel, ist vorgesehen, diese z.B. auf elektronischem Wege durch mindestens einen Computer oder Steuerungsrechner erfolgen zu lassen. Dazu bietet sich z.B. die Verwendung des ohnehin vorhandenen Steuerungsrechners der Füllmaschine an.With regard to the control of these, e.g. pneumatically operated means is provided this e.g. electronically through at least one computer or Control computer to be done. For this purpose, for example, the use of the anyway existing control computer of the filling machine.

Während des Spülens oder Füllens entweicht Gas oder Rückgas aus dem Behälter und gelangt bei geöffnetem Membranverschluss 18 durch das Rückgasrohr 11 in den Rückgaskanal 13. Durch die vorteilhafte Gestaltung der Bohrung 17, den Betrieb der Unterdruckquelle 15 und die sinnvolle Einstellung des Gasstromventils 16 gelingt es, den Gasstrom zwischen den Bauteilen Rückgasrohr 11, Rückgaskanal 13 und Speicherbehälter 12 so einzustellen und in seiner Richtung festzulegen, dass der Strom der aus dem Rückgasrohr 11 austretenden Gase direkt zur Vakuumquelle 15 gelangt und nicht in den Speicherbehälter 12 eindringt, wodurch ein Kontakt von Füllgut und Rückgas sicher vermieden wird.During purging or filling, gas or return gas escapes from the container and arrives at open membrane closure 18 through the return gas pipe 11 in the Rückgaskanal 13. Due to the advantageous design of the bore 17, the operation of the Vacuum source 15 and the sensible adjustment of the gas flow valve 16 succeeds the gas flow between the components return gas pipe 11, return gas channel 13 and storage tank 12 to adjust and set in his direction that the current the gas leaving the return gas pipe 11 passes directly to the vacuum source 15 and does not penetrate into the storage container 12, whereby a contact of contents and Return gas is safely avoided.

Zusätzliche Sicherheit des Abfüllprozesses kann durch einen geringen aber kontinuierlichen Gasstrom aus dem Speicherbehälter 12 in den Rückgaskanal 13 erreicht werden, da dieser, die Bohrung 17 passierende Gasstrom, den Weg durch die Bohrung 17 für das Rückgas blockiert.Additional safety of the filling process can be achieved by a small but continuous Gas flow from the storage tank 12 in the return gas channel 13 is reached be because of this, the bore 17 passing gas flow, the way through the hole 17 blocked for the return gas.

Ebenfalls wird es durch die vorliegende Erfindung ermöglicht, Gasbewegungen innerhalb des Speicherbehälters 12 nahezu vollständig zu vermeiden, wodurch insbesondere bei empfindlichen Füllgütern wie z.B. Wein oder bestimmten Fruchtsäften, unerwünschte Verluste von Alkohol und/oder leicht flüchtigen Geschmacksstoffen deutlich reduziert oder sogar vollständig verhindert werden können.Also, it is possible by the present invention, gas movements within of the storage container 12 almost completely avoided, which in particular for sensitive products such as Wine or certain fruit juices, undesirable losses of alcohol and / or volatile flavorings significantly reduced or even completely prevented.
