Abstract

The method and arrangement are for automatic measurement and evaluation of the distribution of granules in a mixture, esp. of material to be ground, involve sorting, weighing, and a graphic display. This saves much of the labour, time, and running costs of conventional manual methods. The fractions of granules arising from the sorting process are fed directly to a weighing device., which passes measurement value to a processor. The sum of the wts. of the fractions is also measured and fed to the processor in electronic form. A set of sieves contains several sieves (1,2,3,4) in series connected to a balance (6) with a digital measurement transducer (7) connect a computer (8) with a printer (9) and/or display (10).

Verfahren und Vorrichtung zur automatischen Ermittlung undMethod and device for automatic determination and

Auswertung der Kornverteilung eines Körnungsgemisches Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur automatischen Ermittlung und Auswertung der Kornverteilung eines Körnungsgemisches, insbesondere einer Mahlgutprobe, durch Klassierung, Wägung und graphische Darstellung.Evaluation of the grain distribution of a grain mixture The invention relates to a method and apparatus for automatic detection and evaluation of the grain distribution of a grain mixture, in particular a grist sample, through classification, weighing and graphical representation.

Bisher wurde in vielen Fällen die Klassierung, Wägung und graphische Auswertung der Kornverteilung eines Körnungsgemisches von Hand aus vorgenommen. Dies ist Jedoch mit einem hohen Personal-, Zeit- und Kostenaufwand verbunden.So far, in many cases the classification, weighing and graphic Evaluation of the grain distribution of a grain mixture carried out by hand. However, this is associated with a high expenditure of personnel, time and money.

Die Aufgabe der Erfindung besteht darin, ein Verfahren zu schaffen, daß eine automatische Ermittlung und Auswertung der Kornverteilung eines Körnungsgemisches ermöglicht.The object of the invention is to create a method that an automatic determination and evaluation of the grain distribution of a grain mixture enables.

Diese Aufgabe wird dadurch gelöst, daß die bei der Klassierung anfallenden Kornfraktionen unmittelbar einer Wägeeinrichtung zugeführt und von dieser gewichtsmäßig erfaßt werden, und daß die sich daraus ergebenden Meßgrößen einem Rechner zugeleitet werden.This object is achieved in that the resulting in the classification Grain fractions are fed directly to a weighing device and from this by weight are detected, and that the resulting measured variables are fed to a computer will.

Durch diese erfindungsgemäßen Maßnahmen kann die Kornverteilung eines Körnungsgemisches sowohl im kontinuierlichen als auch im diskontinuierlichen Betrieb sehr rasch ermittelt und ausgewertet werden. Auf diese Weise können sehr vorteilhaft im Betrieb auftretende Abweichungen der Kornverteilung eines Körnungsgemisches von vorgegebenen Sollwerten erfaßt und korrigiert werden. Auch Fehlerquellen, die bei der bisher üblichen manuellen Ermittlung und Auswertung der Kornverteilung eines Körnungsgemisches auftraten, werden durch die erfindungsgemäßen Maßnahmen ausgeschaltet.By these measures according to the invention, the grain distribution of a Mixture of grains in both continuous and discontinuous operation can be determined and evaluated very quickly. Doing this can be very beneficial Deviations in the grain distribution of a grain mixture occurring during operation of specified target values are recorded and corrected. Sources of error related to the usual manual determination and evaluation of the grain distribution of a Mixture of grains occurred are eliminated by the measures according to the invention.

In vorteilhafter Weiterbildung der Erfindung werden die Gewichte der Kornfraktionen auf einer Schnellwaage summarisch ermittelt und die Wägeergebnisse in elektronische Meßgrößen umgewandelt. Dies ermöglicht eine besonders genaue Ermittlung und Auswertung der Kornverteilung eines Körnungsgemisches.In an advantageous development of the invention, the weights of the Grain fractions are summarized on a high-speed scale and the weighing results converted into electronic measurands. This enables a particularly precise determination and evaluation of the grain distribution of a grain mixture.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Erläuterung eines in der Zeichnung schematisch dargestellten Verfahrensstammbaumes zur Durchführung des Verfahrens gemäß der Erfindung.Further details, features and advantages of the invention result from the following explanation of one shown schematically in the drawing Process tree for carrying out the method according to the invention.

Einem aus den Sieben 1, 2, 3 und 4 bestehenden Siebprüfsatz wird eine vorbestimmte Mahlgutprobemenge in Pfeilrichtung 5 zugeführt. Die Siebrückstände bzw. Überlaufkornfraktionen I, II, III, IV sowie der Siebdurchgang V werden einer Schnellwaage 6 mit Digitalmeßwandler 7 nacheinander aufgegeben.A sieve test set consisting of sieves 1, 2, 3 and 4 becomes a a predetermined amount of sample quantity of grist is supplied in the direction of arrow 5. The sieve residues or overflow grain fractions I, II, III, IV and the sieve passage V are given to a high-speed scale 6 with digital transducer 7 one after the other.

Die Gewichte dieser Kornfraktionen werden auf der Schnellwaage 6 summarisch ermittelt und die Wägeergebnisse vom Digitalmeßwandler 7 in elektronische Meßgrößen umgewandelt und einem Rechner 8 (Computer) zugeleitet. Im Rechner 8 können sehr vorteilhaft die Meßergebnisse als Masseanteil der Einzelfraktionen oder Staffelsummen (SiebrUckstand oder Siebdurchgang) berechnet und durch einen in der Zeichnung gestrichelt dargestellten Drucker 9 ausgedruckt werden. Darüberhinaus ist es auch möglich, an den Rechner 8 einen Zeichner 10 anzuschließen, der die Körnungskennlinie nach einem vorgegebenen Körnungsnetz oder einer vorgegebenen Funktion, z.B.The weights of these grain fractions are summarized on the high-speed scale 6 determined and the weighing results from the digital transducer 7 into electronic measured values converted and fed to a computer 8 (computer). In the computer 8 can do a lot advantageously the measurement results as a mass fraction of the individual fractions or scale sums (Sieve residue or sieve passage) calculated and dashed by one in the drawing printer 9 shown can be printed out. In addition, it is also possible to the computer 8 to connect a draftsman 10, which the grain size characteristic after a predetermined grain network or a predetermined function, e.g.

RRSB-Funktion (Rosin-Rammler-Sperling-Bennett-Funktion) graphisch aufzeichnet. Auch können vom Rechner Abweichungen von vorher eingegebenen Sollwerten ermittelt und kenntlich gemacht werden. Schließlich kann man auch bei Betriebssiebanalysen mit gleichbleibendem Ausgangsprodukt die Prüfsiebe einschließlich dem darauf befindlichen Siebrückstand und einschließlich des im Siebgewebe haftenden Grenzkornes wiegen, und die sich daraus ergebenden Meßgrößen dem Rechner 8 zur Auswertung zuleiten. In diesem Falle müssen jedoch die jeweiligen Taragewichte dem Rechner 8 zuvor eingegeben werden.RRSB function (Rosin-Rammler-Sperling-Bennett function) graphically records. Deviations from previously entered target values can also be detected by the computer determined and identified. Finally, one can also do company sieve analyzes the test sieves, including the one on them, with the same starting product Weigh the sieve residue and including the grain size adhering to the sieve mesh, and pass the resulting measured variables to the computer 8 for evaluation. In this case, however, the respective tare weights must be entered into the computer 8 beforehand will.
