Description

Die Erfindung bezieht sich auf ein Huborgan mit variablem Hub für Gefäßbehandlungsmaschinen, insbesondere für Füllmaschinen für Gefäße, wobei die Huborgane kreisförmig am Huborgantisch auf Abstand angeordnet sind.The invention relates to a lifting device with variable stroke for vessel treatment machines, in particular for filling machines for vessels, wherein the lifting members are arranged in a circle on Huborgantisch at a distance.

Gefäßfüllmaschinen sind vorzugsweise als rotierende Maschinen ausgelegt, die an ihren Rotoren eine Vielzahl von Füllelementen aufweisen. Diesen Füllelementen sind heb- und senkbare Standteller zugeordnet, die über Zuführsterne die zu befüllenden Gefäße übernehmen. Jedem dieser Standteller ist wiederum ein so genanntes Huborgan zugeordnet, welches dazu bestimmt ist, die auf den Standtellern stehenden Gefäße gegen die Füllelemente anzuheben und anzupressen.
Um diese Funktion zu realisieren, bestehen diese Huborgane in der Regel aus einer Kombination aus einem feststehenden Kolben und einem, diesen Kolben umschließenden, beweglichen Zylinder. Diese Bauteile sind lotrecht angeordnet, wobei der Kolben starr mit dem Rotor der Gefäßfüllmaschine verbunden ist.
Der Zylinder kann in senkrechter Richtung auf und ab bewegt werden.
Der sich zwischen feststehendem Kolben und beweglichem Zylinder ergebende Hubraum wird in den meisten Fällen mit Druckluft beaufschlagt, welche durch eine Bohrung im Kolben geleitet wird, wodurch der Zylinder das Bestreben hat, sich senkrecht nach oben zu bewegen. Diese Bewegung wird durch eine am Zylinder befestigte, um ihre Längsachse drehbar gelagerte Rolle begrenzt, wobei diese Rolle an einer ortsfesten Kurvenbahn anliegt. Durch die Drehbewegung des Rotors der Gefäßfüllmaschine rollt sich die Rolle auf der Kurvenbahn ab, folgt somit deren Kontur und führt dadurch gleichzeitig eine Auf- und Ab-Bewegung durch, welcher aufgrund der konstruktiven Gestaltung auch der Standteller und somit auch das auf diesem befindliche Gefäß folgt.
Vessel filling machines are preferably designed as rotating machines having a plurality of filling elements on their rotors. These filling elements are associated with raised and lowered base plate, which take over Zuführsterne the vessels to be filled. Each of these stand plate is in turn associated with a so-called lifting member, which is intended to raise the standing on the stalls vessels against the filling elements and press.
To realize this function, these lifting elements usually consist of a combination of a fixed piston and, this piston enclosing, movable cylinder. These components are arranged vertically, wherein the piston is rigidly connected to the rotor of the vessel filling machine.
The cylinder can be moved up and down in the vertical direction.
The resulting between fixed piston and movable cylinder displacement is applied in most cases with compressed air, which is passed through a bore in the piston, whereby the cylinder has a tendency to move vertically upwards. This movement is limited by a roller mounted on the cylinder and rotatably mounted about its longitudinal axis, this roller bearing against a stationary curved track. Due to the rotational movement of the rotor of the vessel filling machine, the roller rolls on the curved path, thus follows the contour and thereby simultaneously performs an up and down movement, which follows due to the structural design of the stand and thus also the vessel located thereon ,

In den meisten Anwendungsfällen sind derartige Kurvenbahnen nicht entlang der gesamten Umfangsfläche des Rotors angeordnet, sondern sie befinden sich nur auf einer Teilstrecke des Umfangs, vorzugsweise im Bereich des Gefäßein- und -auslaufs, wo sich die Aufnahmefläche der Standteller auf der Höhenebene der zu- und abführenden Transporteure befinden muss.In most applications, such curved paths are not arranged along the entire peripheral surface of the rotor, but they are only on a part of the circumference, preferably in the region of the vessel inlet and outlet, where the receiving surface of the stand plate on the height level of the and laxative transporters must be located.

Ein derartiges Huborgan wurde z.B. in der DE 39 19 565 vorgeschlagen.
Nachteilig bei einer derartigen Ausgestaltung ist, dass die Hubbewegung des Huborgans ausschließlich durch die Kontur der Kurvenbahn bestimmt wird und Veränderungen der Hubbewegung nur durch einen Austausch der Kurvenbahn realisiert werden können, was in der Praxis sehr zeitaufwändig und somit teuer ist.
Such a lifting member has been proposed for example in DE 39 19 565.
A disadvantage of such an embodiment is that the lifting movement of the lifting member is determined solely by the contour of the curved path and changes in the lifting movement can be realized only by replacing the curved path, which is very time consuming and therefore expensive in practice.

Ein weiteres Huborgan wurde in der GB 441,065 A vorgestellt. Diese Schrift schlägt ein Huborgan vor, welches als Zylinder-Kolbenkombination ausgebildet ist, bei welcher sowohl die Hub-Bewegung, als auch die Rück-Hub-Bewegung des Kolbens und der mit diesem verbundenen Kolbenstange mittels eines Druckmediums ausgeführt werden. Ebenfalls schlägt diese Schrift die Anordnung einer, die Kolbenstange umgebenden Wendelfeder vor, wobei diese Wendelfeder dazu dienen soll, die Vorwärtsbewegung der ausfahrenden Kolbenstange im letzten Bewegungsabschnitt abzubremsen.Another lifting device was presented in GB 441.065A. This document proposes a lifting member, which is designed as a cylinder-piston combination, in which both the stroke movement, and the return stroke movement of the piston and the associated piston rod are carried out by means of a pressure medium. Also, this document proposes the arrangement of a coil spring surrounding the coil spring, this coil spring is intended to slow down the forward movement of the extending piston rod in the last movement section.

Im Rahmen der Bestrebungen zur Kostensenkung stellt sich innerhalb der Getränkeindustrie zunehmend die Aufgabe, unterschiedlichste Getränkeflüssigkeiten mit derselben Füllmaschine abfüllen zu können. Neben der Möglichkeit die einzelnen Verfahrenschritte des Füllvorganges an die Erfordernisse des Füllgutes anpassen zu können, verlangen die Anwender auch eine Möglichkeit, auf einfache Art und Weise zwischen einer Gegendruckfüllung und einer drucklosen Füllung wählen zu können.As part of efforts to reduce costs, the beverage industry is increasingly faced with the task of being able to fill a wide variety of beverage liquids with the same filling machine. In addition to being able to adapt the individual process steps of the filling process to the requirements of the contents, the users also require a way to be able to choose in a simple manner between a counter-pressure filling and a non-pressurized filling.

Der wesentliche Unterschied zwischen beiden Füllverfahren besteht in der Verbindung zwischen Füllelement und dem zu füllenden Gefäß während des Füllprozesses.The essential difference between the two filling methods is the connection between the filling element and the vessel to be filled during the filling process.

Bei einer Gegendruckfüllung befinden sich Füllelement und Gefäß in Dichtlage zueinander, was bedeutet, dass das Gefäß durch das Huborgan mit erheblicher Kraft gegen das Füllelement gedrückt wird, um den Innenraum des Gefäßes gasdicht von der Umgebung abzuschotten. Dieses Füllverfahren findet vor allem bei CO2-haltigen Getränken wie z.B. Bier oder Mineralwasser Anwendung. Bei der drucklosen Füllung hingegen befinden sich Füllelement und Gefäß nicht in Dichtlage zueinander, sondern sind mit Abstand zueinander angeordnet. Dieses Füllverfahren findet bei CO2-freien Getränken wie z.B. Fruchtsäften oder Milch Anwendung.In a counter pressure filling element and vessel are in sealing position to each other, which means that the vessel is pressed by the lifting member with considerable force against the filling member to seal the interior of the vessel gas-tight from the environment. This filling process is mainly used for CO 2 -containing drinks such as beer or mineral water. In the unpressurized filling, however, filling element and vessel are not in sealing position to each other, but are arranged at a distance from each other. This filling process is used for CO 2 -free drinks such as fruit juices or milk.

Da aber der Hub eines Huborgans im wesentlichen konstant ist, bedarf es zur Realisierung einer derartigen Funktion einer speziellen konstruktiven Gestaltung.However, since the stroke of a lifting member is substantially constant, it requires the realization of such a function of a special structural design.

In der Technik ist zur Lösung dieses Problems ein Vorschlag bekannt geworden, bei dem ein Huborgan mit feststehendem Zylinder und beweglichem Kolben verwendet wird, wobei die zugehörige Kolbenstange den Zylinder an beiden Enden überragt. Am oberen Ende der Kolbenstange ist der Standteller befestigt, an seinem unteren Ende eine Anschlagplatte. Bei einer Druckfüllung tritt diese Anschlagplatte nicht in Funktion, die Kolbenstange kann sich soweit nach oben bewegen, bis sich Gefäß und Füllelement in Dichtlage zueinander befinden. Um eine drucklose Füllung zu realisieren, wird auf das untere Ende der Kolbenstange ein Distanzelement aufgesetzt, welches vor der Anschlagplatte angeordnet wird. Da dieses Distanzelement den Bewegungsraum der Anschlagplatte vermindert, bzw. die wirksame Länge des unteren Endes der Kolbenstange reduziert, wird der Hub des Kolbens wirksam begrenzt. Von großen Nachteil bei dieser Vorgehensweise ist der insbesondere bei Füllmaschinen mit zahlreichen Füllstellen hohe Zeitaufwand, den das Auswechseln der Distanzstücke erfordert.In the art to solve this problem, a proposal has become known in which a lifting member with a fixed cylinder and movable piston is used, the associated piston rod projects beyond the cylinder at both ends. At the upper end of the piston rod of the stand plate is fixed, at its lower end a stop plate. In a pressure filling, this stop plate does not come into operation, the piston rod can move as far upward until the vessel and filler are in sealing position to each other. In order to realize a non-pressurized filling, a spacer element is placed on the lower end of the piston rod, which is arranged in front of the stop plate. Since this spacer reduces the movement space of the stop plate, or reduces the effective length of the lower end of the piston rod, the stroke of the piston is effectively limited. Of great disadvantage in this approach is the particular time in filling machines with numerous filling time, which requires the replacement of the spacers.

Ein weiterer Lösungsansatz besteht darin, den Füllerkessel höhenverstellbar auszuführen, wodurch bei konstantem Hub der Hubelemente ebenfalls Einfluss auf das Herstellen einer Dichtlage genommen werden kann. Eine derartige Lösung ist mechanisch sehr aufwändig und somit teuer.Another approach is to perform the filler tank height adjustable, which at constant stroke of the lifting elements also influence on the production of a sealing layer can be taken. Such a solution is mechanically very complex and therefore expensive.

Aufgabe und Ziel der vorliegenden Erfindung ist es, hier Abhilfe und Verbesserung zu schaffen und eine Vorrichtung vorzustellen, welche die oben genannten Nachteile vermeidet und dennoch einen einfachen Wechsel zwischen druckloser Füllung und Gegendruckfüllung erlaubt. Zur Lösung dieser Aufgabe ist ein Huborgan entsprechend dem Patentanspruch 1 ausgebildet. Dazu sieht die Erfindung vor, die Huborgane mit unterschiedlichen Betriebsdrücken zu betreiben, und dass die Huborgane zusätzlich mit einem federbelasteten, verschiebbaren Anschlag ausgestattet werden, welcher den Hub der Huborgane bei einem ersten, niedrigen Betriebsdruck in einer ersten niedrigen Position beendet, und welcher den Hub bei einem zweiten, höheren Betriebsdruck der Huborgane in einer zweiten, höheren Position beendet.Object and purpose of the present invention is to provide a remedy and improvement and to present a device which avoids the disadvantages mentioned above and yet allows a simple change between unpressurized filling and counter-pressure filling. To solve this problem, a lifting member according to the patent claim 1 is formed. To this end, the invention provides to operate the lifting elements with different operating pressures, and that the lifting members are additionally equipped with a spring-loaded, movable stop, which ends the stroke of the lifting members at a first, low operating pressure in a first low position, and which the hub terminated at a second, higher operating pressure of the lifting members in a second, higher position.

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 drawings. All described and / or illustrated features alone or in any combination form the subject matter of the invention, regardless of their summary in the claims or their dependency. At the same time, the content of the claims is made part of the description.

Wie in der Figur 1 dargestellt, sind die Huborgane 1 am äußeren Umfang des Rotors 2 der Gefäßfüllmaschine angeordnet. Zentraler Bestandteil des Huborgans 1 ist der Kolben 4, welcher anhand einer Aufnahme 5 fest mit dem Rotor 2 verbunden ist. Umschlossen wird der Kolben 4 vom einem Zylinder 6, welcher von einem Zylinderrohr 7 und einem Zylinderkopf 8 gebildet wird. Der sich zwischen Kolben 4 , Zylinderrohr 7 und Zylinderkopf 8 ergebende Hubraum 9 wird durch eine im Kolben 4 angeordnete Bohrung mit Druckluft beaufschlagt. Die sich daraus ergebende Aufwärtsbewegung des Zylinders 6 wird durch eine an diesem befestigte, drehbar gelagerte Rolle 10 begrenzt und gesteuert, wobei diese Rolle 10 an der ortsfesten Kurvenbahn 3 anliegt.As shown in Figure 1, the lifting members 1 are arranged on the outer circumference of the rotor 2 of the vessel filling machine. The central component of the lifting member 1 is the piston 4, which is connected by a receptacle 5 fixed to the rotor 2. The piston 4 is enclosed by a cylinder 6, which is formed by a cylinder tube 7 and a cylinder head 8. The resulting between piston 4, cylinder tube 7 and cylinder head 8 displacement 9 is acted upon by a piston arranged in the bore 4 with compressed air. The resulting upward movement of the cylinder 6 is limited and controlled by a rotatably mounted roller 10 fixed thereto, and this roller 10 abuts against the stationary cam track 3.

Am unteren Ende des Zylinders 6 ist an dessen äußerem Umfang mittels eines Distanzstückes 11 ein Anschlagelement 12 befestigt.At the lower end of the cylinder 6, a stop element 12 is attached to the outer periphery by means of a spacer 11.

Am oberen Ende des Zylinders 6 befindet sich ein Aufnahme- und Führungselement 13 für den Zylinder 6. Dieses Aufnahme- und Führungselement 13 ist derart ausgebildet, dass es neben seiner Führungsfunktionen noch weitere Aufgaben übernehmen kann. Dazu beinhaltet dieses Element eine Federelementkammer 14 und eine beweglich zwischen Zylinderrohr 7 und Aufnahme- und Führungselement 13 gelagerte Anschlagmuffe 15.At the upper end of the cylinder 6 is a receiving and guiding element 13 for the cylinder 6. This receiving and guiding element 13 is designed such that it can take on other tasks in addition to its leadership functions. For this purpose, this element includes a spring element chamber 14 and a movably mounted between the cylinder tube 7 and receiving and guiding element 13 stop sleeve 15th

Es ist vorgesehen, innerhalb der Federelementkammer 14 eine zylindrische Schraubenfeder 16 anzuordnen. In Weiterbildungen der vorliegenden Erfindung kann aber auch die Verwendung von anderen, elastischen Elementen wie z.B. elastisch verformbaren Kunststoffelementen, mehreren am Umfang der Federelementkammer 14 angeordneten Schraubenfedern oder weiteren, in der Technik bekannten und für den vorliegenden Anwendungsfall geeigneten Mitteln vorgesehen sein.It is intended to arrange a cylindrical helical spring 16 within the spring element chamber 14. In further developments of the present invention, however, the use of other, elastic elements such as e.g. elastically deformable plastic elements, a plurality of coil springs arranged on the circumference of the spring element chamber 14 or further means known in the art and suitable for the present application.

Durch die in der Federelementkammer 14 unter Vorspannung angeordnete Schraubenfeder 16 wird die im Wesentlichen durch das Zylinderrohr 7 geführte Anschlagmuffe 15 so weit nach unten bewegt, bis sie aufgrund ihrer geometrischen Gestalt gegen einen Anschlag des Aufnahme- und Führungselementes 13 gedrückt wird. In dieser Position ragt das untere Ende der Anschlagmuffe 15 deutlich über die untere Begrenzung des Aufnahme- und Führungselementes 13 hinaus.By arranged in the spring element chamber 14 under bias coil spring 16 which guided essentially through the cylinder tube 7 stop sleeve 15 is moved so far down until it is pressed due to their geometric shape against a stop of the receiving and guiding element 13. In this position, the lower end of the stop sleeve 15 protrudes significantly beyond the lower boundary of the receiving and guiding element 13.

Nachfolgend wird die Vorgehensweise bei einem ersten Füllverfahren beschrieben, bei dem die Gefäße drucklos, also nicht in Dichtlage mit dem Füllventil abgefüllt werden sollen.
Zur Realisierung dieses Verfahrens wird der Hubraum 9 mit einem ersten, niedrigen Druck beaufschlagt. Während der Drehbewegung des Rotors 2 um seine Hochachse folgt der Zylinder 6 der durch die an der Kurvenbahn 3 anliegenden Rolle 10 vorgegebenen Auf- und Ab-Bewegung. Hat der Rotor 2 einen bestimmten Drehwinkel erreicht, so endet die Kurvenbahn 3 in einem kontinuierlichen Auslauf. In der Regel schon vor dem Erreichen dieses Auslaufes hat sich der Zylinder 6 so weit nach oben bewegt, dass das Anschlagselement 12 an der Anschlagmuffe 15 anliegt und sich somit nicht weiter nach oben bewegen kann. Der bei diesem Verfahren verwendete Druck reicht nicht aus, um die in der Federelementkammer 14 befindliche Schraubenfeder 16 zusammenzudrücken, die Aufwärtsbewegung des Huborgans endet somit in dieser Position, das Gefäß befinden sich nicht in Dichtlage mit dem Füllelement.
The procedure for a first filling method is described below, in which the containers are to be filled without pressure, ie not in sealing position with the filling valve.
To implement this method, the displacement 9 is subjected to a first, low pressure. During the rotational movement of the rotor 2 about its vertical axis, the cylinder 6 follows the predetermined by the voltage applied to the cam 3 roll 10 Up and down movement. If the rotor 2 has reached a certain angle of rotation, the cam track 3 ends in a continuous outlet. As a rule, even before reaching this outlet, the cylinder 6 has moved so far upwards that the stop element 12 rests against the stop sleeve 15 and thus can not move further upwards. The pressure used in this method is not sufficient to compress the spring located in the spring element chamber 14 coil spring 16, the upward movement of the lifting member thus ends in this position, the vessel are not in sealing position with the filling element.

Bei einem zweiten Füllverfahren, einem Verfahren zur Gegendruckfüllung wird der Hubraum 9 mit einem zweiten, höheren Druck beaufschlagt. Dieses hat zur Folge, dass das am Zylinderrohr befestigte Anschlagselement 12 mit einer größeren Kraft gegen die Anschlagsmuffe 15 gedrückt wird. Hat die Rolle 10 den Einflussbereich der Kurvenbahn 3 verlassen und ist der im Hubraum 9 anliegende Druck groß genug, so ist das Anschlagelement 12 in der Lage, die Schraubenfeder durch eine Verschiebung der Anschlagmuffe 15 so weit zusammenzudrücken, bis die Anschlagmuffe 15 mit dem oberen Teil der Federelementkammer 14 zusammenstößt. Daraus resultiert eine vergrößerte Hubbewegung des Zylinders 6, das Gefäß befindet sich demzufolge in Dichtlage mit dem Füllelement.In a second filling method, a method for counter-pressure filling of the displacement 9 is acted upon by a second, higher pressure. This has the consequence that the attached to the cylinder tube stop member 12 is pressed with a larger force against the stop sleeve 15. If the roller 10 has left the area of influence of the curved path 3 and if the pressure in the displacement 9 is great enough, then the stop element 12 is able to compress the coil spring by displacing the stop sleeve 15 until the stop sleeve 15 engages with the upper part the spring element chamber 14 collides. This results in an increased stroke movement of the cylinder 6, the vessel is therefore in sealing position with the filling element.

Diese Situation ist anschaulich in der Figur 2 dargestellt.This situation is clearly illustrated in FIG.

In einer weiteren, überaus vorteilhaften Weiterbildung der vorliegenden Erfindung ist vorgesehen, dass hydraulisch und/oder pneumatisch arbeitende Funktions- bzw. Federelemente verwendet werden. Dabei können diese Elemente aus Zylinder und Kolben mit Kolbenstange bestehen, wobei die Kolbenstange als Anschlag für das sich bewegende Huborgan dienen soll. Bewegt sich nun das Huborgan gegen die Kolbenstange, so baut sich im Zylinderraum des Elementes ein entsprechender Druck auf. Übersteigt die Höhe des Druckes einen bestimmten Wert, so öffnet ein Druckbegrenzungsventil und das im Zylinderraum befindliche Druckmedium kann entweichen, wodurch der Kolben weiter einfahren kann, was eine erweiterte Hubbewegung des Huborgans zur Folge hat. Weicht das Huborgan im Rahmen der fortschreitenden Drehbewegung des Rotors wieder zurück, so bewegt ein im und/oder am Element angeordnetes Federelement den Kolben wieder in seine Ausgangsposition zurück. Bleibt der Druck, bei einem zweiten Füllverfahren, im Zylinderraum unterhalb des Wertes, welcher zum Öffnen des Druckbegrenzungsventils erforderlich ist, so kann der Kolben nicht über ein bestimmtes, geringes Maß hinaus in den Zylinder einfahren, wodurch der Hub des Huborgans begrenzt ist.In a further, highly advantageous embodiment of the present invention, it is provided that hydraulically and / or pneumatically operating functional or spring elements are used. These elements may consist of cylinder and piston with piston rod, the piston rod should serve as a stop for the moving lifting member. If now the lifting member moves against the piston rod, a corresponding pressure builds up in the cylinder space of the element. If the height of the pressure exceeds a certain value, a pressure-limiting valve opens and the pressure medium located in the cylinder chamber can escape, as a result of which the piston can continue to retract, which results in an extended lifting movement of the lifting member. Diverge the lifting member back in the context of the progressive rotational movement of the rotor, so moved in and / or on the element spring element moves the piston back to its original position. If the pressure remains, in a second filling method, in the cylinder chamber below the value required to open the pressure relief valve, the piston can not retract beyond a certain, small amount into the cylinder, whereby the stroke of the lifting member is limited.

Bei dem innerhalb des oben beschriebenen Elementes verwendeten Druckmedium kann es sich je nach Variante um ein Gas oder um eine Hydraulikflüssigkeit handeln.Depending on the variant, the pressure medium used within the element described above may be a gas or a hydraulic fluid.
