Description

Vorrichtung zur Bestimmung von Parametern eines Schüttgut-Partikelstromes Device for determining parameters of a bulk material particle flow
Die Erfindung betrifft eine Vorrichtung zur Bestimmung von Partikelparametern eines Schüttgut-Partikelstromes, mit einer Einrichtung zur Partikelformanalyse, die eine wenigstens eine oder mehrere Kameras enthaltende Erfassung- und Auswertungseinrichtung zur Bestimmung von Partikelparametern mittels einer numerischen Auswertung von mit der Kamera erzeugten digitalen Bilddateien aufweist.The invention relates to a device for determining particle parameters of a bulk material particle stream, comprising a device for particle shape analysis, which has a detection and evaluation device containing at least one or more cameras for determining particle parameters by means of a numerical evaluation of digital image files generated by the camera.

Die bekannten Vorrichtungen haben sich an sich bewährt. Nachteilig ist jedoch, dass anhand der optischen Auswertung zwar Aussagen über aus Bilddateien gewinnbare Parameter wie den mittleren Durchmesser oder auch weitergehende Angaben zur Kornformbeschreibung getroffen werden können, dass die gewonnen Informationen insbesondere bei Partikelgemischen in vielen Fällen aber keine klaren Aussagen über die Zusammensetzung des Partikelstromes getroffen werden können.The known devices have proven themselves. The disadvantage, however, is that on the basis of the optical evaluation, statements about parameters obtainable from image files, such as the mean diameter or further information on the particle shape description, can be made that the information obtained, in particular in the case of particle mixtures, in many cases does not make any clear statements about the composition of the particle flow can be.

Gemäß dem zweiten Vorschlag der Erfindung gemäß Anspruch 2, werden nicht nur Aussagen über die Partikelform und -große sowie die stoffliche/chemische Beschaffenheit getroffen, sondern mittels der im Auflichtverfahren betriebenen Farberken- nungskamera wird ergänzend sogar noch eine Farbinformation über die Partikel des Partikelstromes gewonnen. Dies ist für bestimmte Anwendungsfälle vorteilhaft.According to the second proposal of the invention according to claim 2, not only statements about the particle shape and size as well as the material / chemical nature are made, but by means of operated in the incident light color detection camera is in addition even obtained a color information on the particles of the particle flow.

Preferably, the photographic images are taken on particles that fall freely in air or other gas.
Dabei ist es zweckmäßig, dass Spektrometer in einfacher und kompakt bauender Wei- se in die Vorrichtung zu integrieren, beispielsweise, indem man es in einfacher Weise einem Schüttrichter zuordnet, den der Materialstrom, an dem die Messung durchzuführen ist, durchtritt.It is expedient for the spectrometer to be integrated into the device in a simple and compact manner, for example by assigning it in a simple manner to a hopper which the material flow at which the measurement is to be performed passes.
Alternativ ist es denkbar, das Spektrometer einem Förderaggregat wie einem Band oder Dosierer zuzuordnen.Alternatively, it is conceivable to associate the spectrometer with a delivery unit such as a belt or metering device.

Fig. 1 eine schematische Darstellung des Aufbaus einer erfindungsgemäßen Vorrichtung im ,Gegenlichtverfahren arbeitend, und Fig. 2 eine der Figur 1 entsprechende Darstellung, jedoch mit einer im Auflichtverfahren arbeitenden Farberkennungskamera.Fig. 1 is a schematic representation of the structure of a device according to the invention in, working backlight method, and Fig. 2 is a representation corresponding to Figure 1, but with a working in incident light color detection camera.
Fig. 1 zeigt eine Vorrichtung 1 zur Bestimmung von Partikelparametern eines Schüttgut-Partikelstromes. Diese weist eine wenigstens eine oder mehrere Kameras 2 und eine Datenverarbeitungsvorrichtung 4 enthaltende Erfassungs- und Auswertungseinrichtung 3 auf. Die Einrichtung 3 ist zur Bestimmung von Partikelparametern mittels einer numerischen Auswertung von mit der Kamera 2 erzeugten digitalen Bilddateien eines Partikelstromes 5 aus Partikeln 6 ausgelegt. Die Kamera 2 wird mit einem Gegenlicht 10 im Gegenlichtverfahren betrieben, so dass ein nur Graustufen enthaltendes Bild aufgenommen wird, aus dem numerisch als Partikelparameter die Partikelform und/oder die Partikelgröße der Schüttgut-Partikel bestimmbar sind.1 shows a device 1 for determining particle parameters of a bulk material particle flow. This has a detection and evaluation device 3 containing at least one or more cameras 2 and a data processing device 4. The device 3 is designed to determine particle parameters by means of a numerical evaluation of digital image files of a particle stream 5 of particles 6 generated by the camera 2. The camera 2 is operated with a backlight 10 in the backlight method, so that an image containing only gray scale is recorded, from which the particle shape and / or the particle size of the bulk material particles can be determined numerically as a particle parameter.
Vorzugsweise werden die Bilddateien an einem Schüttgut-Partikelstrom 5 aus Partikeln 6 ausgenommen, die durch einen Trichter 7 auf eine Fördereinrichtung - hier ein Förderband 8 - strömen, von dem die Partikel im freien Fall herunterfallen, wobei die Bilddateien vorzugsweise am fallenden Partikelstrom aufgenommen werden.Preferably, the image files on a bulk material particle stream 5 are excluded from particles 6 which flow through a funnel 7 onto a conveyor - here a conveyor belt 8 - from which the particles fall down in free fall, the image files preferably being absorbed by the falling particle flow.
Sodann erfolgt eine numerische Auswertung der digital erzeugten Bilddateien z.B. mit der in der EP 1 696 223 A beschriebenen Methode oder mit einer anderen geeigneten numerisch gestützten Auswertungsmethode.Then there is a numerical evaluation of the digitally generated image files, e.g. with the method described in EP 1 696 223 A or with another suitable numerically supported evaluation method.

Dabei lassen sich die beiden Vorrichtungen erfindungsgemäß ohne weiteres in ein Gerät integrieren. Das Spektrometer 9 wird vorzugsweise dem Schüttrichter 7 oder dem Förderband 8 zugeordnet. Es kann aber auch an anderer Stel- Ie der Vorrichtung in diese integriert werden.With the NIR spectrometer the respective composition of the bulk material flow is determined.
