Abstract
Description
Die Erfindung betrifft eine Sortiervorrichtung für Stückgut, welches über ein Förderband oder dergleichen herangeführt wird, wobei das Stückgut mit Röntgenstrahlung beaufschlagt und die vom Stückgut ausgehende Röntgenstrahlung gemessen wird, und wobei auf der Basis des Messsignals ein Sortiervorgang gesteuert wird.The The invention relates to a sorting device for piece goods, which has a conveyor belt or the like introduced being, whereby the general cargo with X-rays charged and the general cargo outgoing X-radiation is measured, and wherein on the basis of the measurement signal, a sorting operation is controlled.

Aufgabe der Erfindung ist es, ausgehend von bekannten Sortierverfahren und Sortiervorrichtungen Verbesserungen vorzuschlagen, die es erlauben Sortiergut mit sehr ähnlichen Werten für die Materialdichte bzw. ähnlicher Eindringtiefe für die verwendete ionisierende Strahlung auch bei raschem Durchsatz sicher zu trennen, wobei der Analysenaufwand gering gehalten werden soll.task The invention is based on known sorting and Sorting devices suggest improvements that allow it Sorted goods with very similar Values for the material density or similar Penetration depth for the used ionizing radiation safely even at rapid throughput to separate, while the analysis effort is to be kept low.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Detektionseinrichtung zumindest einen energiedispersiven Detektor aufweist, welchem zumindest ein Einkanal-Analysator nachgeschaltet ist, welcher auf eine charakteristische Röntgenemissionslinie eines vorbestimmten chemischen Elementes im Stückgut eingestellt ist, dessen analoges Messsignal ggf. über eine Steuer- und Auswerteeinrichtung die Sortiereinrichtung ansteuert.These Task is inventively characterized solved, that the detection device at least one energy-dispersive Detector, which is followed by at least one single-channel analyzer which is on a characteristic X-ray emission line of a predetermined chemical element in general cargo is set, the analog measurement signal if necessary via a Control and evaluation device controls the sorting device.
Es wird somit die Messung auf eine oder wenige charakteristische Röntgenemissionslinien eines vorbestimmten chemischen Elementes im Stückgut beschränkt, deren Strahlungsintensität mit einer Einkanal-Messung erfasst und daraus ein analoges Messsignal abgeleitet wird. Auf der Basis eines vorgegebenen Schwellwertes des analogen Messsignals wird dann der Sortiervorgang eingeleitet. Der Vorteil besteht darin, dass keine Röntgenfluoreszenzanalyse durchgeführt werden muss, da der Sortiervorgang im günstigsten Fall auf der Messung nur einer charakteristische Röntgenemissionslinien basiert, deren Intensität mit einer Einkanal-Messung erfasst wird. Bei der Trennung von PET-Flaschen und Vinylflaschen genügt z.B. die Messung der Intensität der Cl Kα-Linie um ein eindeutiges Sortiersignal gewinnen zu können.It Thus, the measurement is on one or a few characteristic X-ray emission lines limited to a predetermined chemical element in the cargo whose radiation intensity recorded with a single-channel measurement and from this an analog measurement signal is derived. Based on a predetermined threshold of the analog measuring signal then the sorting process is initiated. The advantage is that no X-ray fluorescence analysis is performed must, since the sorting procedure in the most favorable Case on the measurement of only one characteristic X-ray emission lines based, their intensity is detected with a single-channel measurement. When separating PET bottles and vinyl bottles is enough e.g. the measurement of the intensity of Cl Kα-line to be able to win a clear sorting signal.
Von Vorteil ist es, wenn zumindest ein Referenzmesswert im Emissionsspektrum außerhalb des Energiebereiches der charakteristischen Röntgenemissionslinie mit einer Einkanal-Messung erfasst wird und daraus zumindest ein analoges Referenzsignal abgeleitet wird. Beispielsweise kann das Messsignal mit Hilfe des Referenzsignals normiert werden. Dazu kann das Referenzsignal im Bereich der Anodenstrahlung gewonnen werden.From It is advantageous if at least one reference measured value in the emission spectrum outside the energy range of the characteristic X-ray emission line with a One-channel measurement is detected and from it at least one analog Reference signal is derived. For example, the measurement signal be normalized with the help of the reference signal. For this purpose, the reference signal be obtained in the field of anode radiation.
Gemäß einer vorteilhaften Weiterbildung der erfindungsgemäßen Sortiervorrichtung ist dem Detektor zumindest ein weiterer Einkanal-Analysator nachgeschaltet, welcher auf einen Bereich außerhalb des Energiebereiches der charakteristischen Röntgenemissionslinie eingestellt ist, dessen analoges Referenzsignal zur Normierung des Messsignals dient.According to one advantageous development of the sorting device according to the invention is at least one further single-channel analyzer is connected downstream of the detector, which is on an area outside the Energy range of the characteristic X-ray emission line set is, whose analog reference signal is used to normalize the measurement signal.
