Für zahlreiche technische Anwendungen müssen Behälter mit Flüssigkeiten oder Gasen gefüllt werden. Ein diesbezüglich typisches Anwendungsgebiet sind Kraftfahrzeuge, für die eine Befüllung von Gehäusen, Kreisläufen, Ausgleichbehältern und dergleichen mit Kraft-, Schmier-, Kühl- und sonstigen Betriebsstoffen notwendig ist.For many technical applications, containers must be filled with liquids or gases. A typical field of application in this respect are motor vehicles, for which a filling of housings, circuits, expansion tanks and the like with power, lubricants, coolants and other operating materials is necessary.
Insbesondere bei einer Erstbefüllung an Fertigungslinien beim Hersteller bestehen hohe Anforderungen an eine Befüllung, die mit den bekannten technischen Lösungen jedoch nur bedingt erfüllt werden. An solchen Fertigungslinien erfolgt die erstmalige Befüllung der Baugruppen vorzugsweise mit Füllanlagen, die nach dem Prinzip der sog. Vakuum-Druck-Befüllung arbeiten und beispielsweise aus
Probleme können sich jedoch ergeben, sofern auf einer Fertigungslinie verschiedene Fahrzeugtypen produziert werden. Hierbei kann es beim Befüllvorgang notwendig werden, dass auch unterschiedliche Niveaus mit ein- und demselben Adapter realisiert werden müssen. Dies erfordert eine Pinolenverstellung, für die bisher zwei Varianten üblich sind:
- a) eine Zweipunktverstellung mittels pneumatischem Zylinder, mit der lediglich zwei verschiedene Niveaus realisierbar sind
- b) eine stufenlose Verstellung mittels elektrischem Schrittmotor, mit dem beliebig viele verschiedene Niveaus realisierbar sind
- a) a two-point adjustment by means of a pneumatic cylinder, with only two different levels can be realized
- b) a stepless adjustment by means of electric stepper motor with which any number of different levels can be realized
Allerdings weisen diese beiden technischen Lösungen mehrere Nachteile auf. Bei der Zweipunktverstellung sind vorab zwei Niveaus fest definiert, die nur durch zusätzliche Handhabungen mechanisch verstellt werden können. Die andere Variante mit Schrittmotor ist sehr kostenintensiv und erfordert einen schweren Motor, der relativ viel Bauraum am zugeordneten Adapter beansprucht und somit die Handhabung behindern kann.However, these two technical solutions have several disadvantages. In the two-point adjustment, two levels are defined in advance, which can only be adjusted mechanically by additional manipulations. The other variant with stepper motor is very expensive and requires a heavy motor, which requires a relatively large amount of space on the associated adapter and thus can hinder the handling.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur automatischen Realisierung verschiedener Füllstände in verschiedenen Behältern vorzuschlagen, wobei die Lösung nur mit geringen Kosten verbunden sein sollte und der Befülladapter klein und leicht sein sollte. Weiterhin ist es Aufgabe der Erfindung, ein auf einer Anlage zur Vakuum-Druck-Befüllung ausführbares Verfahren zur Befüllung von Behältern mit verschiedenen Füllhöhen vorzuschlagen.It is therefore the object of the present invention to propose a device for the automatic realization of different levels in different containers, the solution should be associated only at low cost and the filling adapter should be small and light. Furthermore, it is an object of the invention to propose an executable on a system for vacuum-pressure filling process for filling containers with different fill levels.
Die Druckschrift
Die oben genannte Aufgabe wird gelöst, indem der Befülladapter einen ersten Zylinderraum und einen zweiten Zylinderraum an axial gegenüberliegenden Seiten eines Kolbens aufweist, wobei der erste Zylinderraum mit einem Druckgas verbunden ist und der zweite Zylinderraum entweder ebenfalls mit einem Druckgas oder mit einer Federkraft derart beaufschlagt ist, dass der Kolben durch unterschiedliche Drücke und/oder Kräfte im ersten und zweiten Zylinderraum bewegbar und durch gleiche Drücke und/oder Kräfte im ersten und zweiten Zylinderraum lagefixiert feststellbar ist, so dass eine Mündung des Rohres auf mehrere axiale Rohrstellungen zwischen zwei Endstellungen positionierbar ist, an denen das Befüllen und/oder das Absaugen und. dadurch das Einstellen einer Füllhöhe der Flüssigkeit erfolgen kann.The above object is achieved by the Befülladapter having a first cylinder chamber and a second cylinder chamber on axially opposite sides of a piston, wherein the first cylinder chamber is connected to a pressurized gas and the second cylinder chamber is also acted upon either with a compressed gas or with a spring force in that the piston can be fixed by different pressures and / or forces in the first and second cylinder chambers and fixed in position by equal pressures and / or forces in the first and second cylinder chambers, so that an orifice of the pipe can be positioned in several axial pipe positions between two end positions. where the filling and / or the suction and. this can be done adjusting a liquid level.
Der erfindungsgemäße Befülladapter ist zur automatischen Realisierung verschiedener Füllstände ausgebildet. Er ist kaum größer und schwerer als herkömmliche Befülladapter, er weist durch eine stufenlose oder mehrstufige Verstellbarkeit in unterschiedliche axiale Rohrstellungen des Rohres, auf denen eine Befüllung und/oder eine Absaugung des Behälters erfolgen kann, jedoch eine erweiterte Funktionalität auf. Diese Funktionalität wird durch lediglich geringe Modifikationen an einem herkömmlichen Befülladapter und durch die Verwendung weniger zusätzlicher Standardbauelemente erreicht, so dass die vorgeschlagene Lösung auch kostengünstig ist. Durch die Verstellbarkeit ist nicht nur eine Anpassung an verschiedene Behälter möglich, sondern auch eine Optimierung oder Nachregelung der Füllhöhe an demselben Behältertyp.The filling adapter according to the invention is designed for the automatic realization of different filling levels. It is hardly larger and heavier than conventional filling adapters, it has a stepless or multi-stage adjustability in different axial tube positions of the tube, on which a filling and / or an extraction of the container can take place, but an extended functionality. This functionality is achieved by only minor modifications to a conventional filling adapter and achieved by using fewer additional standard components, so that the proposed solution is also cost-effective. Due to the adjustability is not only an adaptation to different containers possible, but also an optimization or readjustment of the level of the same container type.
Es versteht sich für einen Fachmann auf diesem technischen Gebiet, dass zur Befüllung des Behälters der Befülladapter Teil einer Anlage zur Vakuum-Druck-Befüllung ist, die auch eine Steuereinheit umfasst. Komponenten der Anlage außerhalb des Befülladapters, die mit dem Flüssigkeitsanschluss, dem Absauganschluss und dem wenigstens einen Druckgasanschluss verbunden sind, sind dem Fachmann bekannt und auf Grundlage seiner Fachkenntnisse ausgestaltbar. Eine Beschreibung dieser Anlagenkomponenten würde von der Beschreibung der Erfindung ablenken und erfolgt deshalb im Folgenden nur punktuell.It is understood by a person skilled in the art that for filling the container of the filling adapter is part of a system for vacuum pressure filling, which also includes a control unit. Components of the system outside of the filling adapter, which are connected to the liquid connection, the suction connection and the at least one compressed gas connection, are known to the person skilled in the art and can be configured on the basis of his specialist knowledge. A description of these system components would distract from the description of the invention and therefore will be made only in the following.
Der erfindungsgemäße Befülladapter kann in einer Ausführung einen ersten und einen zweiten Druckgasanschluss aufweisen, die jeweils mit dem ersten bzw. mit dem zweiten Zylinderraum verbunden sind. Dabei steht jeder der zwei Druckgasanschlüsse mit einem Proportionalventil in Wirkverbindung. Als Druckgas, auch für alternative Ausführungen der pneumatisch auslösbaren Bewegung des Kolbens wird vorzugsweise Druckluft eingesetzt.In one embodiment, the filling adapter according to the invention can have a first and a second compressed gas connection, which are respectively connected to the first and the second cylinder chamber. Each of the two compressed gas connections is operatively connected to a proportional valve. As compressed gas, also for alternative embodiments of the pneumatically releasable movement of the piston compressed air is preferably used.
In einer anderen Ausführung ist vorgesehen, dass lediglich ein Druckgasanschluss mit einem Proportionalventil in Wirkverbindung steht und dass die andere Seite mit einem festen Druck beaufschlagt wird, der vorzugsweise von einem Druckregler ausgelöst wird.In another embodiment, it is provided that only one compressed gas connection is in operative connection with a proportional valve and that the other side is acted upon by a fixed pressure, which is preferably triggered by a pressure regulator.
In einer nochmals anderen Ausführung steht ebenfalls nur ein Druckgasanschluss mit einem Proportionalventil in Wirkverbindung und die andere Seite wird mit einer Federkraft beaufschlagt.In yet another embodiment is also only a compressed gas connection with a proportional valve in operative connection and the other side is acted upon by a spring force.
In Abhängigkeit der für die konkreten Einsatzmöglichkeiten modifizierten Ausgestaltungen ergeben sich verschiedenartige technische Effekte und letztlich funktionelle Vorteile.Depending on the embodiments modified for the specific applications, various technical effects and ultimately functional advantages result.
Sofern die Baugruppen zur pneumatischen Ansteuerung für den Kolben außerhalb des Befülladapters angeordnet werden, sind besonders kompakte Abmessungen realisierbar.If the assemblies are arranged for pneumatic control of the piston outside of the filling adapter, particularly compact dimensions can be realized.
Sofern zwei elektrisch ansteuerbare pneumatische Proportionalventile vorgesehen sind, können mit den Ventilen im ersten und im zweiten Zylinderraum jeweils unterschiedliche Drücke eingestellt werden. Diese unterschiedlichen Drücke sind zur Bewegung des Kolbens erforderlich. Zur Lagefixierung des Kolbens sind hingegen etwa gleiche Drücke im ersten und zweiten Zylinderraum erforderlich.If two electrically controllable pneumatic proportional valves are provided, with the valves in the first and in the second cylinder chamber in each case different Pressures are set. These different pressures are required to move the piston. For fixing the position of the piston, however, approximately equal pressures in the first and second cylinder chamber are required.
Sofern nur ein Proportionalventil und ein festeinstellbarer Druckregler vorgesehen sind, wird über das Proportionalventil ein variabler Druck in einem Zylinderraum eingestellt. Im anderen Zylinderraum liegt folglich ein konstanter Druck vor. Da auch hier unterschiedliche Drücke zur Kolbenbewegung erforderlich sind, wird mit dem Proportionalventil ein gegenüber dem konstanten Druck abweichender Druck realisiert, falls der Kolben bewegt werden soll. Zur Lagefixierung des Kolbens muss hingegen mit dem Proportionalventil im ersten Zylinderraum ein dem festen Druck im zweiten Zylinderraum entsprechender Druck eingestellt werden.If only a proportional valve and a fixed pressure regulator are provided, a variable pressure in a cylinder chamber is set via the proportional valve. Consequently, there is a constant pressure in the other cylinder space. Since different pressures for piston movement are required here as well, a pressure deviating from the constant pressure is realized with the proportional valve if the piston is to be moved. For fixing the position of the piston on the other hand, a pressure corresponding to the fixed pressure in the second cylinder space has to be set with the proportional valve in the first cylinder chamber.
Sofern ein Proportionalventil und anstelle des festeinstellbaren Druckreglers eine Feder vorgesehen sind, wird über das Ventil auch hier ein variabler Druck in einem Zylinderraum eingestellt. Im anderen Zylinderraum liegt eine dem konstanten Druck funktionell gleiche Federkraft vor. Für diese Variante kann beispielsweise eine metallische Spiralfeder oder eine Elastomerfeder verwendet werden, die den Kolben bei Fehlen einer pneumatischen Gegenkraft in die Ruhestellung bewegt. Da auch hier unterschiedliche Drücke zur Kolbenbewegung erforderlich sind, wird mit dem Proportionalventil ein zur Federkraft abweichender Druck realisiert, falls der Kolben bewegt werden soll. Falls hingegen eine Lagefixierung des Kolbens zu realisieren ist, wird mit dem Proportionalventil eine zur Federkraft gleichartige Druckbeaufschlagung erzeugt.If a proportional valve and a spring are provided instead of the fixed pressure regulator, a variable pressure in a cylinder chamber is also set here via the valve. In the other cylinder chamber is a constant pressure functionally the same spring force. For this variant, for example, a metallic coil spring or an elastomeric spring can be used, which moves the piston in the absence of a pneumatic counterforce in the rest position. Since different pressures for piston movement are required here as well, a pressure deviating from the spring force is realized with the proportional valve if the piston is to be moved. If, however, a positional fixation of the piston is to be realized, a proportional to the spring force similar pressure is generated with the proportional valve.
Unabhängig von der jeweils konkreten Ausführung kann folglich der Kolben entlang seiner Längsachse bewegt werden, so dass eine Mündung des Rohres auf mehrere axiale Rohrstellungen zwischen zwei Endstellungen positionierbar ist, an denen das Befüllen und/oder das Absaugen und dadurch das Einstellen einer Füllhöhe der Flüssigkeit erfolgen kann.Regardless of the specific embodiment, consequently, the piston can be moved along its longitudinal axis, so that a mouth of the tube can be positioned at several axial tube positions between two end positions, at which the filling and / or suction and thereby adjusting a liquid level can.
Der Befülladapter weist außerdem ein Wegmesssystem zur Erfassung der axialen Position des Rohres auf. Das Wegmesssystem ermöglicht eine genaue Erfassung und somit eine genaue Einstellung der Rohrstellung, so dass die zu realisierende Füllhöhe im Behälter genau eingestellt werden kann. Das Wegmesssystem weist z.B. ein Potentiometer, einen Ultraschallsensor, einen optischen oder auch einen magnetischen Inkrementalgeber auf, wobei diese Angaben nur beispielhaft und keinesfalls abschließend zu verstehen sind.The filling adapter also has a position measuring system for detecting the axial position of the tube. The position measuring system enables accurate detection and thus precise adjustment of the pipe position, so that the fill level to be realized in the container can be precisely adjusted. The displacement measuring system has, for example, a potentiometer, an ultrasonic sensor, an optical or even a magnetic incremental encoder, wherein these data are to be understood as examples only and in no way conclusive.
Bei der Positionierung der Pinole wird der durch die beiden Drücke im ersten und zweiten Zylinderraum einstellbare Druckunterschied durch die Steuereinheit so gewählt, dass sich die Pinole in die gewünschte Richtung bewegt. Das Wegmesssystem gibt permanent eine Rückmeldung über die aktuelle Position. Erkennt die Steuereinheit über das Wegmesssystem, dass die Pinole die Zielposition erreicht hat, wird in den beiden Zylinderräumen ein gleicher Druck hergestellt und die Pinole in dieser Position lagefixiert.When positioning the sleeve, the pressure difference that can be set by the two pressures in the first and second cylinder chambers is selected by the control unit so that the sleeve moves in the desired direction. The distance measuring system permanently gives feedback about the current position. If the control unit recognizes via the position measuring system that the sleeve has reached the target position, an equal pressure is produced in the two cylinder chambers and the sleeve is fixed in position in this position.
Neben der oben erläuterten vorrichtungstechnischen Ausgestaltung werden im Rahmen der vorliegenden Erfindung auch verfahrenstechnische Aspekte berücksichtigt. Hierzu wird ein zusätzlicher Verfahrensschritt vorgeschlagen, in dem eine Mündung des Rohres in eine von einer Steuereinheit vorgebbare, zwischen zwei Endstellungen befindliche und einer Füllhöhe in dem Behälter zuordenbare erste axiale Rohrstellung bewegt wird. Somit wird im Unterschied zur bisher üblichen Vorgehensweise nicht eine feste und konstruktiv vorgegebene Rohrstellung angefahren, über welche letztendlich die Füllhöhe im Behälter realisiert wird, sondern es wird eine variable Rohrstellung angefahren. Es ist eine feinstufige bis kontinuierliche Positionseinstellung zwischen den Endstellungen des Rohres möglich.In addition to the device design described above, procedural aspects are also considered within the scope of the present invention. For this purpose, an additional method step is proposed, in which a mouth of the tube is moved into a predetermined by a control unit, located between two end positions and a filling level can be assigned in the container first axial tube position. Thus, in contrast to the usual approach not a fixed and structurally predetermined pipe position approached, over which ultimately the filling level is realized in the container, but it is approached a variable pipe position. It is possible a fine-level to continuous position adjustment between the end positions of the tube.
Vorzugsweise wird die angestrebte Füllhöhe der Flüssigkeit im Behälter durch Absaugen von überschüssiger Flüssigkeit eingestellt. Diese Flüssigkeit kann nur abgesaugt werden, solange sich die Mündung des Rohres unterhalb der Flüssigkeitsoberfläche befindet. Sobald sich die Mündung über dem Pegel der Flüssigkeit befindet, kann keine Flüssigkeit mehr durch das Rohr abgesaugt werden.Preferably, the desired filling level of the liquid is set in the container by suction of excess liquid. This liquid can only be sucked off, as long as the mouth of the tube is below the liquid surface. Once the mouth is above the level of the liquid, no liquid can be sucked through the tube.
