Die gezeigte Gefäßfüllmaschine ist zum Füllen von Flaschen 1 mit einem kohlensäurehaltigen Getränk, z.B. Bier, bei einem überatmosphärischen Gegendruck eingerichtet. Sie weist einen ringförmigen, geschlossenen Vorratsbehälter 2 mit im wesentlichen rechteckigen Querschnitt auf, der um seine senkrechte Mittelachse 3 umläuft. Der Vorratsbehälter 2 ist bis zum Pegel 4 mit dem Getränk und darüber mit einem Spanngas in Form eines hochprozentigen CO2-Luftgemisches mit einem Überdruck von beispielsweise drei bar gefüllt. Die Zuführung des Getränks und des Spanngases erfolgt in der üblichen Weise durch nicht gezeigte radiale Rohrleitungen, Drehverteiler, Regeleinrichtungen usw..The vessel filling machine shown is set up for filling bottles 1 with a carbonated beverage, for example beer, at a superatmospheric counterpressure. It has an annular, closed storage container 2 with an essentially rectangular cross section, which rotates around its vertical central axis 3. The reservoir 2 is filled up to level 4 with the drink and above it with a tension gas in the form of a high-proof CO 2 -air mixture with an overpressure of, for example, three bar. The beverage and the tensioning gas are supplied in the usual way by radial pipes, rotary distributors, regulating devices, etc., not shown.

Am Vorratsbehälter 2 ist gleichmäßig über den Umfang verteilt eine Vielzahl identischer Füllorgane 5 angeordnet, von denen jedem ein steuerbares Huborgan 6 für die Flaschen 1 sowie eine steuerbare Zentrierglocke 7 für die Flaschenmündung zugeordnet ist.The reservoir 2 is even over the circumference distributed a plurality of identical filling elements 5 arranged, each of which has a controllable lifting element 6 for the bottles 1 and a controllable centering bell 7 for the Bottle mouth is assigned.

Jedes Füllorgan 5 weist einen an der Unterseite des Vorratsbehälters 2 befestigten Ventilblock 8 auf, an dessen Unterseite eine senkrechte, zylindrische Auslauföffnung 9 für die Flüssigkeit ausgebildet ist. Die Auslauföffnung 9 geht nach oben hin über einen konischen Ventilsitz 10 in eine erweiterte senkrechte Bohrung 11 über, die sich ihrerseits an eine im Boden des Vorratsbehälters 2 ausgebildete senkrechte Bohrung 12 anschließt. An der Oberseite des Ventilblocks 8 ist ein mit mehreren Längsschlitzen 13 versehenes Rohrstück 14 befestigt, das mit der Bohrung 11 fluchtet und durch die Bohrung 12 hindurchragt. Das Rohrstück 14 endet oberhalb des Pegels 4 und ist am oberen Ende mit nach innen gerichteten Führungsbolzen 15 für einen senkrecht stehenden, höhenbeweglichen Ventilkörper 16 ausgestattet.Each filler 5 has one on the underside of the Reservoir 2 attached valve block 8, at the Underside of a vertical, cylindrical outlet opening 9 is designed for the liquid. The outlet opening 9 goes up through a conical valve seat 10 in an expanded vertical bore 11 over that in turn to one in the bottom of the storage container 2 trained vertical bore 12 connects. At the Top of the valve block 8 is one with several Longitudinal slots 13 provided pipe section 14 attached with the bore 11 is aligned and through the bore 12 protrudes through. The pipe section 14 ends above the level 4 and is at the top with inward facing Guide pin 15 for a vertical, height-movable valve body 16 equipped.

Der Ventilkörper 16 ist am unteren Ende konisch verjüngt und mit einem Dichtring versehen, der mit dem Ventilsitz 10 zusammenwirkt. Der Ventilkörper 16 bildet so zusammen mit dem Ventilsitz 10 das Flüssigkeitsventil 17 des Füllorgans 5. Ist der Ventilkörper 16 abgesenkt, wie auf der linken Seite der Zeichnung dargestellt ist, kann keine Flüssigkeit aus der Auslauföffnung 9 austreten. Ist der Ventilkörper 16 angehoben, wie auf der rechten Seite der Zeichnung dargestellt ist, so kann die Flüssigkeit aus dem Vorratsbehälter 2 durch die Schlitze 13 und den Ringraum zwischen dem Rohrstück 14 und dem Ventilkörper 16 sowie durch die Bohrungen 12 und 11 weitgehend ungehindert und strömungsgünstig zur Auslauföffnung 9 und durch diese hindurch in eine an das Füllorgan 5 unter Zwischenschaltung der Zentrierglocke 7 angepreßte Flasche 1 einlaufen. Dabei wird die Öffnungsstellung durch den Kontakt zwischen Führungsstiften 18, die am Ventilkörper 16 befestigt sind und diesen in der Bohrung 11 lose zentrieren, und einem am oberen Ende der Bohrung 11 am Ventilblock 8 ausgebildeten ringförmigen Anschlag 19 definiert.The valve body 16 is tapered at the lower end and provided with a sealing ring which is connected to the valve seat 10 cooperates. The valve body 16 thus forms together with the valve seat 10, the liquid valve 17 of the filling element 5. Is the valve body 16 lowered, as on the left Side of the drawing is shown, no liquid emerge from the outlet opening 9. Is the valve body 16 raised as on the right side of the drawing is shown, the liquid from the Storage container 2 through the slots 13 and the annular space between the pipe section 14 and the valve body 16 and through the holes 12 and 11 largely unimpeded and aerodynamically to the outlet opening 9 and through this through to the filling element 5 with interposition the centering bell 7 run in pressed bottle 1. Here the opening position is determined by the contact between Guide pins 18 which are attached to the valve body 16 and loosely center it in the hole 11, and one on formed the upper end of the bore 11 on the valve block 8 annular stop 19 defined.

Der Ventilkörper 16 weist eine durchgehende Bohrung auf, die sich am unteren Ende unmittelbar über dem Flüssigkeitsventil 17 unter Bildung eines weiteren Ventilsitzes 20 konisch verengt. Der Ventilsitz 20 wirkt mit einem senkrechten, höhenbeweglichen weiteren Ventilkörper 21 zusammen und bildet mit diesem das Spanngasventil 22 des Füllorgans 5. Der Ventilkörper 21 ist im wesentlichen rohrförmig, wobei sein Außendurchmesser wesentlich kleiner ist als der Innendurchmesser des Ventilkörpers 16, in dessen Bohrung er konzentrisch angeordnet ist. Am unteren Ende weist der Ventilkörper 21 eine Verdickung 23 auf, die an der Unterseite einen mit dem Ventilsitz 20 zusammenwirkenden Dichtring trägt. Die Verdickung 23 ist am Mantel mit mehreren Führungsrippen 24 versehen, durch die der Ventilkörper 21 höhenbeweglich im Ventilkörper 16 geführt ist. An den Ventilsitz 20 schließt sich nach unten hin ein Rückgasrohr 25 an, das lösbar im unteren Ende des Ventilkörpers 16 befestigt ist und unter Bildung eines Ringraums für die Flüssigkeit konzentrisch durch die Auslauföffnung 9 hindurch frei nach unten ragt. Das Rückgasrohr 25 ist am unteren Ende mit einem Schirmchen für die Flüssigkeit versehen, steht gegenüber der Unterseite des Ventilblocks 8 vor und ragt während des Füllvorgangs in den Kopfraum einer an das Füllorgan 8 angepreßten Flasche 1. Es leitet einerseits mit seinem Schirmchen die aus der Auslauföffnung 9 austretende Flüssigkeit an die Innenwandung der Flasche 1 und ermöglicht außerdem die Zufuhr bzw. Abfuhr von Spanngas aus dem Vorratsbehälter 2 in bzw. aus der Flasche 1. Ist der Ventilkörper 21 abgesenkt, wie auf der linken Seite der Zeichnung dargestellt ist, so ist der Durchgang für Spanngas gesperrt. Ist der Ventilkörper 21 angehoben, wie auf der rechten Seite der Zeichnung dargestellt ist, so wird über die Bohrung des Ventilkörpers 16 und das Rückgasrohr 25 eine Verbindung zwischen dem überhalb des Pegels 4 befindlichen Spanngasraum des Vorratsbehälters 2 und dem Innenraum einer Flasche 1 hergestellt.The valve body 16 has a through bore that at the bottom just above the liquid valve 17 conical to form a further valve seat 20 narrowed. The valve seat 20 acts with a vertical, vertically movable further valve body 21 together and forms with it the tensioning gas valve 22 of the filling element 5. The valve body 21 is substantially tubular, wherein its outer diameter is much smaller than that Inner diameter of the valve body 16, in the bore of which he is arranged concentrically. At the bottom, the Valve body 21 has a thickening 23 on the Bottom one interacting with the valve seat 20 Seals wear. The thickening 23 is on the jacket provided several guide ribs 24 through which the Valve body 21 guided vertically in the valve body 16 is. The valve seat 20 closes at the bottom Return gas pipe 25, which is detachable in the lower end of the Valve body 16 is attached and forming a Annulus for the liquid concentrically through the Outlet opening 9 projects freely downwards. The Return gas pipe 25 is at the lower end with an umbrella for provided the liquid is opposite the bottom of the Valve blocks 8 and protrudes during the filling process in the Head space of a bottle 1 pressed against the filling element 8 on the one hand, with his umbrella directs the from Outlet opening 9 emerging liquid on the inner wall the bottle 1 and also allows the supply or discharge of tension gas from the reservoir 2 in or out of the Bottle 1. Is the valve body 21 lowered, as on the is shown on the left side of the drawing Passage blocked for span gas. Is the valve body 21st raised as on the right side of the drawing is shown, so the bore of the valve body 16 and the return gas pipe 25 a connection between the located above the level 4 span gas space of the Storage container 2 and the interior of a bottle 1 produced.

Der Ventilkörper 21 ist gegenüber dem Ventilkörper 16 nach oben hin verlängert und durch eine im Deckel des Vorratsbehälters 2 befestigte Führungsbuchse 26 beweglich aus diesem herausgeführt. Durch einen am Ventilkörper 21 einerseits und an der Führungsbuchse 26 andererseits befestigten elastischen Faltenbalg 27 ist der Durchtritt gas- und flüssigkeitsdicht abgeriegelt. An dem nach oben aus dem Vorratsbehälter 2 herausragenden Ende des Ventilkörpers 21 ist ein Bügel 28 befestigt, der seinerseits an der Kolbenstange eines einfach wirkenden Pneumatikzylinders 29 befestigt ist. Letzterer ist starr mit der Führungsbuchse 26 verbunden. Außerdem ist zwischen den Bügel 28 und die Führungsbuchse 26 eine den Ventilkörper 21 umgebende Druckfeder 30 eingesetzt, welche den Ventilkörper 21 in seine obere, geöffnete Stellung zu bewegen sucht.The valve body 21 is opposite to the valve body 16 extended at the top and by a in the lid of the Storage container 2 attached guide bushing 26 movable led out of this. By one on the valve body 21 on the one hand and on the guide bush 26 on the other attached elastic bellows 27 is the passage sealed gas and liquid tight. At the top of it the reservoir 2 protruding end of the valve body 21 is a bracket 28 attached, which in turn on the Piston rod of a single-acting pneumatic cylinder 29 is attached. The latter is rigid with the guide bush 26 connected. In addition, between the bracket 28 and the Guide bushing 26 surrounding valve body 21 Compression spring 30 is used, which the valve body 21 in tries to move its upper, open position.

Der Ventilkörper 21 wird über seine gesamte Länge ohne Hohlraumbildung von einer stabförmigen Sonde 31 durchsetzt, deren Außendurchmesser dem Innendurchmesser des Ventilkörpers 21 entspricht. Die Sonde 31 ragt unter Zwischenschaltung von Dichtringen nach unten hin aus der Verdickung 23 am unteren Ende des Ventilkörpers 21 frei heraus und erstreckt sich ohne weitere Abstützung unter Bildung eines Ringraums konzentrisch durch das Rückgasrohr 25 hindurch, aus dessen Öffnung sie nach unten hin frei herausragt. Die Sonde 31 ragt somit in den Halsraum einer an das Füllorgan 5 angepreßten Flasche 1 in etwa bis in den Bereich der gewünschten Füllhöhe. Das obere Ende der Sonde 31 ragt aus dem Ventilkörper 21 heraus und ist mittels eines Klemmstücks 32 gegenüber dem Ventilkörper 21 verstellbar fixiert. Die Sonde 31 macht somit die normale Hubbewegung des Ventilkörpers 21 des Gasventils 22, die durch den Pneumatikzylinder 29 hervorgerufen wird, im vollen Umfang mit. Außerdem ist am oberen Ende der Sonde 31 mittels eines Steckers 33 ein Meßkabel 34 angeschlossen, das zu einer elektronischen Steuereinrichtung 35 führt. Diese steuert im Ausführungsbeispiel ausschließlich die Pneumatikzylinder 29 und damit die Flüssigkeitsventile 17 und die Spanngasventile 22 in Zusammenwirkung mit Druckfedern 36, die zwischen die Führungsbolzen 15 einerseits und das umgebogene obere Ende der Ventilkörper 16 andererseits eingesetzt sind.The valve body 21 is without over its entire length Cavity formation penetrated by a rod-shaped probe 31, whose outer diameter is the inner diameter of the Valve body 21 corresponds. The probe 31 protrudes Interposition of sealing rings down from the Thickening 23 at the lower end of the valve body 21 free out and extends under without further support Formation of an annular space concentrically through the return gas pipe 25 through, from the opening of which they are released downwards protrudes. The probe 31 thus projects into the neck space the filling element 5 pressed bottle 1 approximately into the Range of the desired fill level. The top of the probe 31 protrudes from the valve body 21 and is by means of a Clamping piece 32 adjustable relative to the valve body 21 fixed. The probe 31 thus makes the normal stroke movement of the valve body 21 of the gas valve 22 by the Pneumatic cylinder 29 is caused in full With. In addition, at the top of the probe 31 by means of a Plug 33 a measuring cable 34 connected to a electronic control device 35 leads. This controls in Exemplary embodiment exclusively the pneumatic cylinder 29 and thus the liquid valves 17 and the span gas valves 22 in cooperation with compression springs 36 which between the Guide pin 15 on the one hand and the bent upper end the valve body 16 are used on the other hand.

Ist der Pneumatikzylinder 29 mit Druckluft beaufschlagt, so wird über den Bügel 28 entgegen der Kraft der Druckfeder 30 der Ventilkörper 21 direkt nach unten gegen den Ventilsitz 20 gepreßt; das Spanngasventil 22 ist somit geschlossen. Gleichzeitig wird indirekt über die Verdickung 23 und den Ventilsitz 20 auch der Ventilkörper 16 entgegen der Kraft der Druckfeder 36 nach unten gegen den Ventilsitz 10 gepreßt; das Flüssigkeitsventil 17 ist somit gleichfalls geschlossen. Diesen Zustand nimmt das Füllorgan 5 am Ende eines Füllvorgangs bzw. zwischen zwei Füllvorgängen ein.If the pneumatic cylinder 29 is pressurized with compressed air, then is against the force of the compression spring 30 via the bracket 28 the valve body 21 directly down against the valve seat 20 pressed; the span gas valve 22 is thus closed. At the same time, indirectly via the thickening 23 and Valve seat 20 also the valve body 16 against the force the compression spring 36 down against the valve seat 10 pressed; the liquid valve 17 is thus also closed. The filling element 5 takes this state at the end a filling process or between two filling processes.

Ist der Druckluftzylinder entlüftet, so wird durch die Kraft der Druckfeder 30 der Bügel 28 und damit der Ventilkörper 21 in seine obere Endstellung gedrückt; das Spanngasventil 22 ist somit geöffnet. Das Flüssigkeitsventil 17 bleibt unter Einwirkung des Überdrucks im Vorratsbehälter 2 zunächst noch geschlossen. Erst wenn durch das über das Spanngasventil 22 und das Rückgasrohr 25 in die Flasche 1 einströmende Spanngas den Druck ausgeglichen worden ist, wird auch der Ventilkörper 16 durch die Druckfeder 36 angehoben; das Flüssigkeitsventil 17 ist somit geöffnet. Die Flüssigkeit kann dann über das Flüssigkeitsventil 17 und die Auslauföffnung 9 in die Flasche 1 einlaufen. Sobald der Flüssigkeitsspiegel den unteren Meß- bzw. Endbereich der z.B. als Leitfähigkeits- oder Kurzschlußsonde ausgebildeten Sonde 31 erreicht, sendet diese über die Meßleitung 34 ein Signal an die Steuereinrichtung 35. Diese löst sofort oder nach einer einstellbaren Verzögerungszeit die Luftzufuhr zum Pneumatikzylinder 29 aus, wodurch das Flüssigkeitsventil 17 und das Spanngasventil 22 zusammen geschlossen werden. Die Flasche 1 ist exakt bis zum gewünschten Pegel gefüllt.If the air cylinder is vented, the force the compression spring 30, the bracket 28 and thus the valve body 21 pressed into its upper end position; the span gas valve 22 is thus open. The liquid valve 17 remains below Influence of the excess pressure in the reservoir 2 initially closed. Only when through the span gas valve 22nd and the return gas pipe 25 flowing into the bottle 1 Span gas has been equalized, the pressure will also Valve body 16 raised by the compression spring 36; the Liquid valve 17 is thus open. The liquid can then via the liquid valve 17 and the Run the outlet opening 9 into the bottle 1. Once the Liquid level the lower measuring or end range of the e.g. trained as a conductivity or short-circuit probe When probe 31 is reached, it sends it in via measuring line 34 Signal to the control device 35. This triggers immediately or after an adjustable delay time, the air supply to the Pneumatic cylinder 29, whereby the liquid valve 17th and the span gas valve 22 are closed together. The Bottle 1 is filled exactly to the desired level.

Um nach dem in vorbeschriebener Weise abgelaufenen eigentlichen Füllvorgang ein gezieltes Entlasten der an das Füllorgan 5 angepreßten Flasche 1 zu ermöglichen, ist im Ventilblock 8 ein schräg nach unten hin in die Auslauföffnung 9 einmündender Entlastungskanal 37 ausgebildet. Dieser führt zu einem mechanisch steuerbaren Entlastungsventil 38, über das er mit einem Kanal 39 und weiter mit einer an der Unterseite des Vorratsbehälters 2 ausgebildeten Ringleitung 40 verbunden werden kann. In dieser herrscht Atmosphärendruck, so daß durch kurvengesteuertes, kurzzeitiges Öffnen des Entlastungsventils 38 ein gezielter Druckabbau in der Flasche 1 vor dem Abziehen vom Füllorgan 5 durchgeführt werden kann, insbesondere, wenn im Kanal 39 eine Drossel angeordnet ist. Beim Reinigen der Gefäßfüllmaschine dient die Ringleitung 40 zur Rückführung der über den Vorratsbehälter 2 zugeführten Reinigungsflüssigkeit im geschlossenen Kreislauf. In ähnlicher Weise können weitere in die Auslauföffnung 9 einmündende Kanäle und Steuerventile, beispielsweise für Vakuum, angeordnet werden.To after the expired in the manner described above actual filling process a targeted relief of the to the Filling member 5 to allow pressed bottle 1 is in Valve block 8 an obliquely down in the Outlet opening 9 opening relief channel 37 educated. This leads to a mechanically controllable Relief valve 38, through which he with a channel 39 and continue with one on the underside of the storage container 2 trained ring line 40 can be connected. In this prevails at atmospheric pressure, so that by cam-controlled, brief opening of the Relief valve 38 a targeted pressure reduction in the Bottle 1 carried out before pulling from the filling element 5 can be, especially if a choke in channel 39 is arranged. When cleaning the vessel filling machine the ring line 40 for the return of the Storage tank 2 supplied cleaning liquid in the closed cycle. Similarly, others can in the outlet opening 9 channels and Control valves, for example for vacuum, are arranged.
