Abstract
Description
Die Erfindung betrifft ein Verfahren zum sicheren Abfüllen bei ventilgesteuerten Abfüllanlagen gemäß dem Oberbegriff des Anspruchs 1 und wie aus der
In verschiedenen Industriebereichen werden ventilgesteuerte Abfüllanlagen eingesetzt, um flüssige Produkte in spezielle Behälter, meist Flaschen, abzufüllen. Problematisch hierbei ist häufig die Schaumbildung beim Abfüllprozess. Handelt es sich bei dem Abfüllprodukt um eine seifige Flüssigkeit, zum Beispiel Haarshampoo, so kann die Schaumbildung, die durch Luftblasen beim Abfüllen verursacht wird, leicht ein Überlaufen der Shampooflasche beim Abfüllvorgang bewirken. Ein solches Überlaufen an einer einzelnen Abfüllstation kann den Stillstand der gesamten Abfüllanlage nach sich ziehen. Je nach dem, welche Menge des Produkts übergelaufen ist, sind umfangreiche Reinigungsmaßnahmen notwendig.Valve-controlled filling systems are used in various industrial sectors to fill liquid products into special containers, usually bottles. The problem here is often the foaming during the filling process. If the filling product is a soapy liquid, for example hair shampoo, the foaming caused by air bubbles during filling can easily cause the shampoo bottle to overflow during the filling process. Such spillover at a single filling station can result in the stoppage of the entire bottling plant. Depending on the amount of product overflow, extensive cleaning measures are necessary.
Die Menge des Produktes, die bei jedem Abfüllvorgang abgefüllt werden soll, wird häufig mit Durchflussmessgeräten (z. B. Dosimass, Dosimag der Fa. Endress+Hauser) gemessen und über eine Dosiersteuerung eingestellt.The amount of product to be filled in each filling process is often measured with flowmeters (eg Dosimass, Dosimag from Endress + Hauser) and adjusted via a dosing control.
Treten beim Abfüllvorgang Luftblasen auf, so ist die Durchflussmessung je nach Messprinzip mehr oder weniger gestört. Die vom entsprechenden Messgerät gelieferten Durchflusswerte weichen vom tatsächlich vorhandenen Durchfluss ab. Bei Coriolis-Massedurchflussmessgeräten und bei magnetisch-induktiven Durchflussmessgeräten sind aufwendige Verfahren zur Luftblasenerkennung bekannt. Aufgrund der komplizierten Auswerteverfahren dauert es eine gewisse Zeit, bis das Gerät eine Luftblasenbildung erkennt und diese z. B. an seinem Statusausgang anzeigt. Für schnelle Abfüllvorgänge, mit Abfüllzeiten unter einer Sekunde, sind solche Verfahren nicht geeignet.If air bubbles occur during the filling process, the flow measurement is more or less disturbed depending on the measuring principle. The flow rates provided by the meter differ from the actual flow rate. With Coriolis mass flowmeters and magnetic-inductive flowmeters elaborate methods for bubble detection are known. Due to the complicated evaluation process, it takes some time until the device detects an air bubble formation and this z. B. at its status output. For fast filling operations, with filling times under one second, such methods are not suitable.
Die Aufgabe der Erfindung besteht deshalb darin, ein Verfahren zum sicheren Abfüllen bei ventilgesteuerten Abfüllanlagen anzugeben, das die oben genannten Nachteile nicht aufweist, das insbesondere das Überlaufen während des Abfüllprozesses aufgrund von Luftblasenbildung sicher verhindert und das einfach und kostengünstig realisierbar ist.The object of the invention is to provide a method for safe filling in valve-controlled filling systems, which does not have the disadvantages mentioned above, in particular reliably prevents the overflow during the filling process due to bubble formation and which is easy and inexpensive to implement.
Gelöst wird diese Aufgabe durch die im Anspruch 1 angegebenen Merkmale.This object is achieved by the features specified in
Die wesentliche Idee der Erfindung besteht darin, die Bildung von Luftblasen im Abfüllprodukt, die das Überlaufen beim Abfüllvorgang verursachen, schnell und einfach durch die Auswertung mehrere Durchflusswerte D(ti), zu Zeiten zu denen ein konstanter Durchfluss an der betreffenden Abfüllstation herrschen sollte, zu erkennen.The essential idea of the invention is that the formation of air bubbles in the filling product, which cause the overflow during the filling process, quickly and easily by the evaluation of multiple flow values D (ti), at times when there should be a constant flow at the filling station concerned detect.
Falls signifikante Abweichungen im Durchfluss festgestellt werden, wird das betreffende Abfüllventil vorzeitig geschlossen.If significant flow deviations are detected, the fill valve in question is closed prematurely.
Vorteilhafte Weiterentwicklungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are specified in the subclaims.
Bei den Durchflussmessgeräten kann es sich z. B. um Coriolis- bzw. magnetischinduktive Durchflussmessgeräte handeln.The flow meters may, for. B. Coriolis or magnetic inductive flow meters.
Die Erfindung eignet sich besonders für schnelle Abfüllvorgänge, bei denen die Zeitdauer zwischen dem Öffnen und Schließen des Abfüllventils unter 1-5 Sekunden liegt.The invention is particularly suitable for fast filling operations in which the time between opening and closing of the filling valve is less than 1-5 seconds.
In einer Weiterentwicklung der Erfindung werden die Impulse, die am Impulsausgang der Durchflussmessgeräte ausgegeben werden, zur Bestimmung des aktuellen Durchflusswertes genommen.In a further development of the invention, the pulses which are output at the pulse output of the flowmeters are used to determine the current flow value.
Nachfolgend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail with reference to an embodiment shown in the drawing.

Konstante Abfüllbedingungen erhält man nur, wenn der Kopfdruck KP im Vorlagebehälter 40 konstant gehalten wird. Hierfür ist ein Druckmesser 46 am Vorlagebehälter 40 vorgesehen, der den Kopfdruck KP im Behälter 40 misst. Über eine Druckluft-Zufuhrleitung 42, in der ein Ventil 44 vorgesehen ist, kann der Kopfdruck KP eingestellt werden. Die entsprechende Regelung des Kopfdrucks erfolgt ebenfalls über die Dosiersteuerungseinheit 10. Hierfür wird der aktuelle Kopfdruck als 4-20 mA-Signal über die Messsignalleitung MSL 17 an die Dosiersteuerungseinheit 10 übertragen. Über die Steuerungssignalleitung SSL17 wird das Ventil 44 von der Dosiersteuereinheit 10 entsprechend angesteuert, um dadurch den Kopfdruck KP im Behälter 40 konstant zu halten.Constant filling conditions are only obtained if the top pressure KP in the

Es findet natürlich keine mathematische Integration der Abfüllkurve in der Dosiersteuerungseinheit 10 statt.

Die Nachlaufmenge, d. h. die Menge Abfüllprodukt die nach dem Schließbefehl noch abfließt, ist damit entsprechend berücksichtigt.Of course, there is no mathematical integration of the filling curve in the

Die Erfindung geht davon aus, dass zwischen den Zeitpunkten T2 und T3 die Durchflussrate in etwa konstant ist.
