Mi 1chprobenvordosierung für Mi1chsammelfahrzeuge 1.0 Description
Milk sample pre-dosing for milk collection vehicles
1.1 Problem:1.1 Issue:
Mi1chsammelfahrzeuge müssen von der anzusaugenden Milch, von jeden Milchlieferanten, automatisch eine Probe nehmen, die Aufschluß auf die Gesamtqualität der Milch wiedergibt. Dazu muß vom Anfang bis zum Ende der Milchannahme ein Milchstrom gebildet werden, der in ein Vorgefäß, genannt Stapler, fließt. Dadurch entsteht eine Milchmenge die der Gesamtmenge repräsentativ ist. Aus dieser Milchmenge wird die Probemenge (ca. 50 cm3) abgezweigt und abgefüllt. Das erste Problem ist, daß, sowohl bei kleinen, wie auch bei großen abzusaugenen Milchmengen, der Stapler nach Abschluß der Absaugung nicht überfließen darf, aber auch eine Mindestmenge beinhalten muß. Wenn dieser Punkt nicht erfüllt wird, würde das Probeergebnis verfälscht sein. Außerdem darf der Behälter nicht zu groß ausfallen, da dieser in der Annahmekabine untergebracht werden muß. Das zweite Problem besteht darin, daß die Milchreste vom Vor 1ieferant, die an den Wandungen vom Stapler und in den Schlauchleitungen bleiben, so gering wie möglich zu halten sind.Milk collection vehicles must automatically take a sample of the milk to be sucked in from each milk supplier, which provides information on the overall quality of the milk. To do this, a milk flow must be formed from the beginning to the end of the milk intake, which flows into a preliminary container, called a stacker. This creates a quantity of milk that is representative of the total quantity. The sample quantity (approx. 50 cm 3 ) is branched off from this quantity of milk and filled. The first problem is that, whether for small or large quantities of milk to be sucked out, the stacker must not overflow after the suction has been completed, but must also contain a minimum quantity. If this point is not met, the test result would be falsified. In addition, the container must not be too large, as it has to be housed in the intake cabin. The second problem is that the milk residue from the previous supplier that remains on the walls of the stacker and in the hoses must be kept as low as possible.
1.2 Stand der Technik:1.2 State of the art:
Stand der Technik ist zur Zeit, daß 2 Milchströme abgezweigt werden. Der große Milchstrom fließt in den Stapler und ein kleiner Milchstrom, der für große Milchlieferanten vorgesehen ist, in einen kleinen zusätzlichen Vorstapler. Ist der Stapler, der vom großen Milchstrom gefüllt wird voll (ca. bei 2001 angesaugter Milch), so wird der Stapler leergesaugt und mit dieser Milch werden die Schlauchleitungen zur Abfüllung gespült. Nach Beendigung dieses Vorganges gelangt die Milch vom kleinen Stapler in den großen Stapler. Diese Milchmenge, zusammen mit der Milchmenge die von nun über den kleinen Stapler in den großen Stapler fließt, repräsentiert die Milch von großen Milchlieferanten. Das Problem besteht nun darin, daß der Stapler nicht gespült wird und das man außerdem noch einen zusätzlichen Stapler benötigt.The current state of the art is that 2 milk streams are diverted. The large milk stream flows into the stacker and a small milk stream, intended for large milk suppliers, into a small additional pre-stacker. If the stacker, which is filled by the large milk stream, is full (approx. 2001 milk sucked in), the stacker is drained and the hoses for filling are rinsed with this milk. After this process is complete, the milk from the small stacker goes into the large stacker. This amount of milk, together with the amount of milk that now flows from the small stacker into the large stacker, represents the milk from large milk suppliers. The problem now is that the stacker is not rinsed and an additional stacker is also required.

1.4 Vorteilhafte Wirkung der Erfindung1.4 Advantageous effect of the invention
Die vorteilhafte Wirkung der Erfindung besteht darin, daß eine begrenzte Vormenge an Milch, die der Gesamtmenge repräsentativ ist, gesammelt wird und das durch automatisches Umschalten der Zulaufmenge ein weites AnIieferungsmiIchmengenspektrum abgedeckt werden kann. Außerdem sind die Verschleppungswerte durch das Vorspülen gering, d.h. die Restmengen vom Vor1ieferanten werden herausgespült.The advantageous effect of the invention is that a limited preliminary quantity of milk, which is representative of the total quantity, is collected and that a wide range of milk quantities can be covered by automatically switching the feed quantity. In addition, the carryover values are low due to the pre-rinsing, i.e. the residual quantities from the previous supplier are rinsed out.

1.6.3 Funktionsablauf:1.6.3 Functional sequence:
Wenn keine Probe genommen werden braucht, hält der ZyI. E die Ansaugleitung offen. Die ZyI. C ; D ; u. F schließen die Probeleitungen. Muß Probe genommen werden, halten die ZyI. C ; D u. F die Leitungen offen. ZyI. G stellt den großen Teilstrom ein. ZyI. B öffnet den Weg 1-2 ,so daß im Stapler der gleiche Unterdruck vorhanden ist wie im Luftabscheider. ZyI. A ist immer, wenn abgesaugt wird, geschlossen. Wird nun Milch angesaugt, fließt ein Teilstrom zum Stapler. Signalisiert der Schalter S2 das Milch angekommen ist, so wird mit einer kurzen Zeitverzögerung kurzzeitig Druckluft am Luftanschluß 1 eingelassen. Die Zeitverzögerung ist dafür vorhanden, daß die Zuleitung zum Stapler ganz mit Milch gefüllt wird. Diese Milch läuft, aufgrund der Druckluft, nun mit erhöhter Geschwindigkeit in den Stapler. Durch ein Prallblech am Ende der Zuleitung zum Stapler wird mit dieser Milch der Stapler gespült und gelangt von dort in die Meßkammer. Nun schließen nach einer weiteren Zeitverzögerung die ZyI. C u. D. Im Stapler sammelt sich nun, da der große Milchstrom weiterfließt eine Milchmenge, die der Gesamtmenge repräsentativ ist. Gleichzeitig, wenn ZyI C und D schließen, wird Druckluft, über den Luftanschluß 2 in die Meßkammer geleitet, so daß die Milch, die vorher den Stapler gespült hat, nun auch die Schlauchleitungen zur Abfüllung spült. An der Abfüllung wird die Milch abgeleitet. Der Spülvorgang ist beendet. Da der Teilstrom, der den Stapler füllt, groß ist, ist der Stapler schnell voll. Ist die Schaltmarke 1 vom, Schalter Sl noch nicht erreicht und die Absaugung beendet (bei kleinen Milchlieferanten), so wird von außen die Abfüllung eingeleitet. Nun öffnen die ZyI. C u. D . Der ZyI. B öffnet den Weg 1 - 3 , so daß im Stapler Normaldruck herrscht. Die Milch fließt nun in die Meßkammer. Die überschüssige Milch wird abgesaugt, da im Luftabscheider ein Unterdruck herrscht. Während dieser Vorgang läuft, schließt ZyI. E u. F die Leitungen, so daß keine Milch, die den Vorgang stören würde, angesaugt werden kann. ZyI. D schließt nach einer Zeit wieder, und mit Hilfe von Druckluft am Luftanschluß 2 gelangt die Probemenge zur Abfüllung, wo diese dann in eine Probeflasche abgefüllt wird. Nach einer weiteren Zeit gehen sämtliche Zylinder in deren Ausgangsstellung zurück, so daß nun eine neue Milchmenge angesaugt werden kann. Im zweiten Fall, bei großen Milchlieferanten, wo der Stapler voll ist, bevor die Absaugung beendet ist, wird, wenn die Schaltmarke 1 vom Schalter Sl erreicht ist, umgeschaltet.If no sample needs to be taken, cylinder E keeps the suction line open. Cylinders C, D, and F close the sample lines. If a sample needs to be taken, cylinders C, D, and F keep the lines open. Cylinder G sets the large partial flow. Cylinder B opens path 1-2 so that the same negative pressure is present in the stacker as in the air separator. Cylinder A is always closed when suction is taking place. If milk is now sucked in, a partial flow flows to the stacker. If switch S2 signals that milk has arrived, compressed air is briefly let in at air connection 1 after a short time delay. The time delay is there so that the supply line to the stacker is completely filled with milk. This milk now flows into the stacker at an increased speed due to the compressed air. Through a baffle plate at the end of the supply line to the forklift, the forklift is rinsed with this milk and from there it reaches the measuring chamber. Now, after a further time delay, cylinders C and D close. As the large milk flow continues, a quantity of milk that is representative of the total quantity collects in the forklift. At the same time, when cylinders C and D close, compressed air is fed into the measuring chamber via air connection 2, so that the milk that previously rinsed the forklift now also rinses the hose lines for filling. The milk is drained off at the filling point. The rinsing process is finished. As the partial flow that fills the forklift is large, the forklift quickly fills up. If the switch mark 1 of the switch S1 has not yet been reached and the suction has ended (for small milk suppliers), filling is initiated from the outside. Now cylinders C and D open. The cylinder. B opens the path 1 - 3 so that normal pressure prevails in the stacker. The milk now flows into the measuring chamber. The excess milk is sucked out because there is a negative pressure in the air separator. While this process is running, cylinders E and F close the lines so that no milk that would disrupt the process can be sucked in. Cylindrical valve D closes again after a while and with the help of compressed air at air connection 2 the sample quantity is taken to the filling station, where it is then filled into a sample bottle. After a further period of time all cylinders return to their starting position so that a new quantity of milk can now be sucked in. In the second case, with large milk suppliers, where the stacker is full before the suction is finished, the switch is switched over when the switch mark 1 of the switch Sl is reached.
Nun öffnet der ZyI. C u. B öffnet den Weg 1 - 3 . ZyI. D bleibt geschlossen. Der Stapler wird nun bis zur Schaltmarke 2 vom Schalter Sl leergesaugt, da diese die ZyI. B u. C. wieder in ihrer alten Lage zurückgehen läßt. ZyI. G schaltet bei diesen Vorgang auf den kleinen Teilstrom um. Der gesamte Ablauf mu3 so bemessen sein, daß die Restmenge, die im Stapler bleibt, so groß ist, als wenn der kleine Teilstrom den Stapler bis zum Zeitpunkt der Umschaltung gefüllt hätte. Nun ist auch nach der Umschaltung gegeben, daß die Milchmenge (Restmenge + neu hinzufließende Menge), die sich im Stapler befindet, repräsentativ der Gesamtmenge ist. Ist nun die Absaugung beendet, wird die Abfüllung genau wie im ersten Fall eingeleitet und beendet.Now the cylinders C and B open the path 1 - 3. Cylinder D remains closed. The stacker is now drained by switch S1 up to the switch mark 2, as this allows cylinders B and C. to return to their old position. During this process, cylinder G switches to the small partial flow. The entire process must be designed so that the remaining quantity that remains in the stacker is as large as if the small partial flow had filled the stacker up to the time of switching. Now, even after switching, the amount of milk (remaining quantity + newly added quantity) in the stacker is representative of the total quantity. Once the suction has ended, the filling is started and ended exactly as in the first case.

Wenn der Mischbehälter leergesaugt werden soll, schließt das Reinigungszulaufventil (ZyI.A) die Reinigungsleitung. Das 3-Wege-Venti1 (ZyI.B) schließt den Weg zwischen Luftabscheider und Mischbehälter und öffnet den Weg zwischen Mischbehälter und Normaldruck (nach Außen). Nun kann der Mischbehälter über ein Auslaufventil (ZyI.C) leergesaugt werden, da er über das 3-Wege-Venti1 belüftet wird.When rinsing is required, a valve (ZyI.A) opens the cleaning supply line. The line splits into the air separator, which is part of every milk measuring system, and the 3-way valve (ZyI.B). The 3-way valve is controlled during rinsing so that the path to the mixing container is open. The cleaning solution, which is pressed into the cleaning line from the outside with the help of a pump, flows into the mixing container and the air separator. There it rinses the containers with the help of spray heads that are mounted at the ends of the lines.
If the mixing container is to be drained, the cleaning inlet valve (ZyI.A) closes the cleaning line. The 3-way valve1 (ZyI.B) closes the path between the air separator and the mixing container and opens the path between the mixing container and normal pressure (to the outside). The mixing container can now be drained via an outlet valve (ZyI.C), as it is ventilated via the 3-way valve1.
