The fill quantities also remain during the opening and closing process of the filling valve disregarded. The accuracy of the known Filling process is therefore limited.
- the method according to the invention for filling containers with a pressurized liquid with the characteristic features of claim 1 has in contrast the advantage that it works very precisely. This will achieved according to the invention in that the liquid pressure is constantly measured during the filling process, so that occurring pressure fluctuations are taken into account.

Between the rail sections 13 and 14 or 14 and 15 one controllable via a reject device 16 Weighing device 17, 18 for one packaging container each 10 arranged, one of which 17 the tare weight G1, and the other 18 the gross weight G2 the Packaging container 10 detected and a control device 19th as input variable.
- control device 19 are, for example product-specific data, such as the viscosity curve of the Fluid over temperature as well as device data saved.
- product-specific data such as the viscosity curve of the Fluid over temperature
- device data saved With the control device 19 is an input / output unit 20 connected, in particular a Target filling quantity M or a target filling weight of Packaging container 10 to the control device 19th can be entered.
- the Filling device 22 includes a cyclical transport the packaging container 10 one of the number of each conveying cycle to be filled packaging container 10 corresponding number of Filling heads 23, for example six, each one on and have removable hollow filling needle 24. Every filling head 23 is with a metering valve 25 for the liquid coupled, with all metering valves 25 of the Control device 19 can be controlled synchronously together.
- the metering valves 25 are connected to a via short lines 26 common tubular manifold 30 connected in the one Liquid pressure P1 prevails.
- the distributor 30 is in turn via a line 33 and a Quick release device 34 with a storage container 35 for the liquid connected.
- the pressure drop between the with the liquid fully filled manifold 30 and individual metering valves 25 is, for example, by a Arrangement of the metering valves 25 in the same vertical Distance to the distributor 30 always the same size, and in the Control device 10 stored as a factor.
- the reservoir 35 is a Pressure line 36 is pressurized with a gas pressure P2.
- Pressure P2 generally increases the pressure Liquid at the metering valves 25, and thus a large one Outflow rate from the reservoir 35 enables which is especially the case with highly viscous liquids Flow behavior favors.

- the duration of the time intervals ⁇ t between the individual Measurements of fluid pressure P1 should be chosen this way be that even during the opening and closing process of the metering valves 25 detects liquid pressures P1, and on the control device 19 are forwarded. From these For reasons there is a value for ⁇ t of 200 ⁇ sec. proven, the adequate resolution even during opening and Closing process of the filling valves 25 guaranteed.
- the device described above works as follows:
- the packaging container 10 are from the screw conveyor 21 fed to the filling device 22 in cycles.
- the filling needles 24 of the Filling heads 23 lowered and into the packaging container 10 introduced.
- a corresponding Control signal Z to the metering valves 25 through the Control device 19 the filling of the target filling quantity M in the Packaging container 10 initiated, i.e. the control signal Z, for example, energizes a coil in the Metering valve 25 so that its needle lifts off the valve seat.

- the partial volumes ⁇ M are calculated from the time intervals ⁇ t between the individual measurements of the liquid pressures P1, the respective the value supplied to the control device 19 Fluid pressure of P1, as well as one in the Control device 19 stored functional relationship k (p1) between the respective value of P1 and the resulting value in the Dosing valves 25 resulting flow rate per Time unit.
- This limit value M (max) which causes the control signal Z to end, is in the simplest case the desired filling quantity M itself.
- the limit value M (max) stored in the control device 19 can also be selected to be smaller in accordance with the closing characteristics of the filling valves 25, so that for example, the filling quantity or the partial volumes .DELTA.M are also taken into account that enter the containers 10 during the closing process (after the control signal Z has failed) of the metering valves 25. This means that in this case the limit value M (max) is smaller than the target filling quantity M.
- Control device 19 The accuracy of the partial volume calculation ⁇ M Control device 19 is by taking into account the Temperature sensor 31 detected temperature T of the liquid elevated. This is achieved in that Control device 19 for the flow / viscosity characteristics the respective liquid are stored so that for Calculation of the individual partial volumes ⁇ M additionally on the corresponding temperature-corrected functional context k is accessed, i.e. the value of factor k is also depends on the temperature [k (P1, T)].

Then the packaging container 10 by the conveyor screw 12 cyclically another Processing station, for example a sealing station, promoted. At the same time repeats itself for new in the Filling machine conveyed packaging container 10 the process as described above.
- the value is sufficient of the liquid pressure P1 only during the actual one Filling process. Usually and for Control purposes in the event of any malfunction of the Filling machine, however, the fluid pressure P1 becomes constant measured and fed to the control device 19.
- the time intervals ⁇ t it is also conceivable for the time intervals ⁇ t to be so large to choose that the opening and closing of the Dosing valves 25 with respect to the partial volumes ⁇ M no longer is taken into account exactly, and in this case for opening and closing the metering valves 25 fixed partial volumes ⁇ M (fixed) (according to the metering valve characteristics) to assume. Even in this case, the accuracy improved compared to known filling methods because Pressure fluctuations during the actual filling be taken into account.

Description
Die Erfindung geht aus von einem Verfahren zum Befüllen von Behältern mit einer unter Druck stehenden Flüssigkeit nach der Gattung des Anspruchs 1. Aus der JP 10 46 392 B4 ist bereits ein derartiges Verfahren bekannt geworden. Bei diesem Verfahren wird der Flüssigkeitsdruck nach dem Öffnen eines Füllventils einmalig gemessen, worauf eine Steuereinrichtung aufgrund des gemessenen Flüssigkeitsdruckes eine Füllzeit bzw. Öffnungszeit für das Füllventil für eine bestimmte Füllmenge berechnet. Nachteilig bei dem bekannten Verfahren ist, daß während des Füllvorganges auftretende Druckschwankungen, die zu einer Änderung der Durchflußmenge an dem Füllventil führen, nicht berücksichtigt werden. Weiterhin bleiben auch die Füllmengen während des Öffnungs- und Schließvorganges des Füllventils unberücksichtigt. Die Genauigkeit des bekannten Füllverfahrens ist daher beschränkt.The invention is based on a method for filling Containers with a liquid under pressure the genus of claim 1. From JP 10 46 392 B4 Such a method has already become known. At This procedure uses the fluid pressure after opening of a filling valve measured once, whereupon a Control device based on the measured Liquid pressure a filling time or opening time for the Filling valve calculated for a certain filling quantity. A disadvantage of the known method is that during the Filling process occurring pressure fluctuations that lead to a Do not change the flow rate at the filling valve be taken into account. The fill quantities also remain during the opening and closing process of the filling valve disregarded. The accuracy of the known Filling process is therefore limited.
Das erfindungsgemäße Verfahren zum Befüllen von Behältern mit einer unter Druck stehenden Flüssigkeit mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß es sehr genau arbeitet. Dies wird erfindungsgemäß dadurch erreicht, daß der Flüssigkeitsdruck während des Abfüllvorganges ständig gemessen wird, so daß auftretende Druckschwankungen berücksichtigt werden.The method according to the invention for filling containers with a pressurized liquid with the characteristic features of claim 1 has in contrast the advantage that it works very precisely. this will achieved according to the invention in that the liquid pressure is constantly measured during the filling process, so that occurring pressure fluctuations are taken into account.
Weiterhin können auch die Durchflußmengen währned des Öffnungs- und Schließvorganges des Füllventils erfaßt, und bei der Berechnung der Füllvolumina berücksichtigt werden. Furthermore, the flow rates during the Opening and closing process of the filling valve is detected, and be taken into account when calculating the filling volumes.
Weitere Vorteile und vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens zum Befüllen von Behältern mit einer unter Druck stehenden Flüssigkeit ergeben sich aus den Unteransprüchen und der Beschreibung.Further advantages and advantageous developments of the Method according to the invention for filling containers with a pressurized liquid result from the Subclaims and the description.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Die einzige Figur 1 zeigt eine Füllmaschine in einer schematischen Darstellung.An embodiment of the invention is in the drawing shown and is described in more detail in the following description explained. The only Figure 1 shows a filling machine in a schematic representation.
Die in der Figur 1 dargestellte Füllmaschine zum Dosieren
und Abfüllen einer Flüssigkeit in Verpackungsbehälter 10 hat
eine Fördereinrichtung 11, mit der Verpackungsbehälter 10,
wie beispielsweise Ampullen oder Vials, hintereinander
angeordneten Behandlungsstationen zugeführt werden. Die
Fördereinrichtung 11 weist eine Transportschnecke 12 zum
taktweisen oder kontinuierlichen Transport der
Verpackungsbehälter 10 auf. Die Verpackungsbehälter 10
stehen und gleiten auf Schienenstücken 13 bis 15. Zwischen
den Schienenstücken 13 und 14 beziehungsweise 14 und 15 ist
jeweils eine über eine Ausschleußeinrichtung 16 ansteuerbare
Wägeeinrichtung 17, 18 für jeweils einen Verpackungsbehälter
10 angeordnet, von denen die eine 17 das Tara-Gewicht G1,
und die andere 18 das Brutto-Gewicht G2 der
Verpackungsbehälter 10 erfaßt und einer Steuereinrichtung 19
als Eingangsgröße zuführt.The filling machine for dosing shown in Figure 1
and filling a liquid into packaging container 10
a
In der Steuereinrichtung 19 sind beispielsweise
produktspezifische Daten, wie der Viskositätsverlauf der
Flüssigkeit über der Temperatur sowie Daten der Vorrichtung
abgespeichert. Mit der Steuereinrichtung 19 ist eine Ein/Ausgabeeinheit
20 verbunden, über die insbesondere eine
Sollfüllmenge M bzw. ein Sollfüllgewicht der
Verpackungsbehälter 10 an die Steuereinrichtung 19
eingegeben werden kann.In the
Oberhalb der Fördereinrichtung 11 ist im Bereich des
Schienenstücks 14 eine Abfülleinrichtung 22 angeordnet. Die
Abfülleinrichtung 22 umfaßt bei einem taktweisen Transport
der Verpackungsbehälter 10 eine der Zahl der pro Fördertakt
zu füllenden Verpackungsbehälter 10 entsprechende Anzahl von
Abfüllköpfen 23, beispielsweise sechs, die jeweils eine auf-
und abbewegbare hohle Füllnadel 24 haben. Jeder Abfüllkopf
23 ist mit je einem Dosierventil 25 für die Flüssigkeit
gekoppelt, wobei alle Dosierventile 25 von der
Steuereinrichtung 19 gemeinsam synchron ansteuerbar sind.
Die Dosierventile 25 sind über kurze Leitungen 26 mit einem
gemeinsamen, rohrförmigen Verteiler 30 verbunden, in dem ein
Flüssigkeitsdruck P1 herrscht. Der Verteiler 30 ist
seinerseits über eine Leitung 33 und eine
Schnellspanneinrichtung 34 mit einem Vorratsbehälter 35 für
die Flüssigkeit verbunden. Das Druckgefälle zwischen dem mit
der Flüssigkeit vollständig gefüllten Verteiler 30 und den
einzelnen Dosierventilen 25 ist beispielsweise durch eine
Anordnung der Dosierventile 25 in gleichem vertikalen
Abstand zum Verteiler 30 stets gleich groß, und in der
Steuereinrichtung 10 als Faktor abgespeichert.Above the
In dem Vorratsbehälter 35 befindet sich vorteilhafterweise
die Menge an Flüssigkeit, die während einer
Produktionsschicht zur Abfüllung der Verpackungsbehälter 10
benötigt wird. Dadurch ergibt sich, daß die Füllhöhe im
Vorratsbehälter 35 bei jedem Abfüllzyklus nur in sehr
geringem Maße abnimmt. Der Vorratsbehälter 35 ist über eine
Druckleitung 36 mit einem Gasdruck P2 beaufschlagt.It is advantageously located in the
Vorteilhafterweise besteht dabei eine Beeinflussung zwischen
den Drücken P1 und P2, so daß P2 beispielsweise von der
Steuereinrichtung 19 so geregelt wird, daß sich stets ein
Druck P1 einstellt, dessen Toleranz zum Beispiel +/- 0,05
bar beträgt. Somit können verschiedene Anordnungen des
Vorratsbehälters 35 an der Füllmaschine sowie ein sinkender
Flüssigkeitsspiegel in dem Vorratsbehälter 35 ausgeglichen
werden.There is advantageously an influence between
the pressures P1 and P2, so that P2, for example, from the
Durch den Druck P2 wird generell ein höherer Druck der
Flüssigkeit an den Dosierventilen 25, und damit eine große
Abflußgeschwindigkeit aus dem Vorratsbehälter 35 ermöglicht,
was insbesondere bei hochviskosen Flüssigkeiten das
Fließverhalten begünstigt.Pressure P2 generally increases the pressure
Liquid at the
Im Verteiler 30 sind ein Temperatursensor 31 zur Erfassung
einer Flüssigkeitstemperatur T und ein Drucksensor 32 zur
Erfassung des Flüssigkeitsdruckes P1 angeordnet. Die beiden
Sensoren 31, 32 sind ebenfalls mit der Steuereinrichtung 19
verbunden.A temperature sensor 31 for detection is in the distributor 30
a liquid temperature T and a
Wesentlich ist, daß insbesondere der Flüssigkeitsdruck P1
kontinuierlich in bestimmten Zeitabständen Δt,
beispielsweise alle 150 µsec. bis alle 250 µsec. gemessen,
und der Steuereinrichtung 19 als Eingangsgröße zugeführt
wird. Die Dauer der Zeitabstände Δt zwischen den einzelnen
Messungen des Flüssigkeitsdruckes P1 sollte so gewählt
werden, daß auch während des Öffnungs- und Schließvorganges
der Dosierventile 25 Flüssigkeitsdrücke P1 erfaßt, und an
die Steuereinrichtung 19 weitergeleitet werden. Aus diesen
Gründen hat sich ein Wert für Δt von 200 µsec. bewährt, der
eine ausreichende Auflösung auch während des Öffnungs- und
Schließvorganges der Füllventile 25 gewährleistet.It is essential that in particular the liquid pressure P1
continuously at certain time intervals Δt,
for example every 150 µsec. until every 250 µsec. measured,
and supplied to the
Die oben beschriebene Vorrichtung arbeitet wie folgt:
Die Verpackungsbehälter 10 werden von der Transportschnecke
21 der Abfülleinrichtung 22 taktweise zugefördert. Sobald je
ein Verpackungsbehälter 10 unter seinem zugeordneten
Abfüllkopf 23 positioniert ist, werden die Füllnadeln 24 der
Abfüllköpfe 23 abgesenkt und in die Verpackungsbehälter 10
eingeführt. Gleichzeitig wird durch ein entsprechendes
Ansteuersignal Z an die Dosierventile 25 durch die
Steuereinrichtung 19 das Abfüllen der Sollfüllmenge M in die
Verpackungsbehälter 10 eingeleitet, d.h. das Ansteuersignal
Z bewirkt beispielsweise eine Bestromung einer Spule im
Dosierventil 25, so daß dessen Nadel vom Ventilsitz abhebt.The device described above works as follows:
The
Die Berechnung der abgefüllten Füllmenge M (ist), und somit
die Dauer des Ansteuersignales Z an die Dosierventile 25
erfolgt dadurch, daß von der Steuereinrichtung 19
fortlaufend Teilvolumina ΔM berechnet und während der Dauer
des Ansteuersignales Z aufsummiert werden. Die Teilvolumina
ΔM berechnen sich aus den Zeitabständen Δt zwischen den
einzelnen Messungen der Flüssigkeitsdrücke P1, dem jeweils
der Steuereinrichtung 19 zugeführten Wert des
Flüssigkeitsdruckes von P1, sowie einem in der
Steuereinrichtung 19 abgelegten Funktionszusammenhang k (p1)
zwischen dem jeweiligen Wert von P1 und der daraus in den
Dosierventilen 25 resultierenden Durchflußmenge pro
Zeiteinheit.The calculation of the filled filling quantity M (ist), and thus
the duration of the control signal Z to the
Die Steuereinrichtung 19 berechnet die in einen Behälter 10
abgefüllte Füllmenge M (ist) somit gemäß folgender Formel:
Die Genauigkeit der Teilvoluminaberechnung ΔM der
Steuereinrichtung 19 wird durch die Berücksichtigung der vom
Temperatursensor 31 erfaßten Temperatur T der Flüssigkeit
erhöht. Dies wird dadurch erreicht, daß in der
Steuereinrichtung 19 die Durchfluß/Viskositätskennlinien für
die jeweilige Flüssigkeit abgespeichert sind, so daß zur
Berechnung der einzelnen Teilvolumina ΔM zusätzlich auf den
entsprechenden temperaturkorrigierten Funktionszusammenhang
k zugegriffen wird, d.h., daß der Wert des Faktors k auch
von der Temperatur abhängig ist [k(P1, T)].The accuracy of the partial volume calculation
Nachdem die Sollfüllmenge M in die Verpackungsbehälter 10
eingebracht ist werden die Füllnadeln 24 durch die
Abfüllköpfe 23 wieder aus den Verpackungsbehältern 10
herausgehoben. Anschließend werden die Verpackungsbehälter
10 durch die Förderschnecke 12 taktweise einer anderen
Bearbeitungsstation, beispielsweise einer Verschließstation,
zugefördert. Gleichzeitig wiederholt sich für neu in die
Füllmaschine geförderte Verpackungsbehälter 10 der Vorgang
wie oben beschrieben.After the target filling quantity M into the
Um die exakte Dosierung der Flüssigkeitsmenge und damit der
Sollfüllmenge M durch die Füllmaschine zu kontrollieren bzw.
zu regeln, werden stichprobenartig über die
Ausschleußeinrichtungen 16 einzelne Verpackungsbehälter 10
entnommen und den Wägeeinrichtungen 17, 18 zugeführt. Die
tatsächlich dosierte Flüssigkeitsmenge M (ist) wird von der
Steuereinrichtung 19 als Differenz des Brutto-Gewichts G2
und des Tara-Gewichts G1 errechnet. Dabei ist es mit Hilfe
der sogenannten statistischen Prozeßkontrolle (SPC) möglich,
beim Unter- oder Überschreiten von definierten
Eingriffsgrenzen, beispielsweise der Flüssigkeitsmenge M
(ist), aber auch des Tara-Gewichts G1 der
Verpackungsbehälter 10, von der Steuereinrichtung 19 ein
entsprechend korrigiertes Ansteuersignal Z für die
Dosierventile 25 zu ermitteln.To the exact dosage of the amount of liquid and thus the
Check the set filling quantity M by the filling machine or
to regulate, are sampled on the
Ergänzend wird erwähnt, daß es prinzipiell genügt, den Wert
des Flüssigkeitsdruckes P1 nur während des eigentlichen
Füllvorganges zu erfassen. In der Regel und für
Kontrollzwecke bei etwaigen Funktionsstörungen der
Füllmaschine wird der Flüssigkeitsdruck P1 jedoch ständig
gemessen und der Steuereinrichtung 19 zugeführt.In addition, it is mentioned that, in principle, the value is sufficient
of the liquid pressure P1 only during the actual one
Filling process. Usually and for
Control purposes in the event of any malfunction of the
Filling machine, however, the fluid pressure P1 becomes constant
measured and fed to the
Darüber hinaus ist es auch denkbar, die Zeitabstände Δt so
groß zu wählen, daß der Öffnungs- und Schließvorgang der
Dosierventile 25 in bezug auf die Teilvolumina ΔM nicht mehr
exakt berücksichtigt wird, und in diesem Fall für das Öffnen
und Schließen der Dosierventile 25 feste Teilvolumina ΔM
(fest) (entsprechend der Dosierventilcharakteristik)
anzunehmen. Selbst in diesem Fall ist die Genauigkeit
gegenüber bekannten Füllverfahren verbessert, da
Druckschwankungen während des eigentlichen Abfüllens
berücksichtigt werden.In addition, it is also conceivable for the time intervals Δt to be so
large to choose that the opening and closing of the
