Description

Die Erfindung betrifft eine Vorrichtung zum Erkennen von störenden Partikeln, insbesondere Trashteilen, Nissen, Schalennissen, Noppen u. dgl., in textilem Fasergut, z. B. Baumwolle, Chemiefasern u. dgl., bei der eine Meßstrecke mit einem durchsichtigem Element für das Fa­ sergut vorgesehen ist, wobei an der Meßstrecke ein Sensor zur Er­ mittlung des Verschmutzungsgrades angeordnet ist, bei der die Vorrichtung eine Kamera, z. B. eine Diodenzeilen-Kamera, eine elektronische Auswerteeinrichtung (Bildverarbeitungseinheit) eine Klassifiziereinrichtung, eine Zähleinrichtung und einen Rechner aufweist, nach Hauptpatent 39 28 279.The invention relates to a device for detecting disruptive Particles, especially trash parts, nits, shell nits, nubs u. Like., in textile fiber material, for. B. cotton, man-made fibers and. the like, in which a measuring section with a transparent element for the company sergut is provided, with a sensor for Er on the measuring section averaging of the degree of pollution is arranged at which the Device a camera, e.g. B. a diode line camera, a electronic evaluation device (image processing unit) Classifying device, a counting device and a computer according to main patent 39 28 279.

Aufgabe der Erfindung ist es, die Vorrichtung zum Erkennen von störenden Partikeln und die Auswertung der Meßergebnisse noch weiter zu verbessern.The object of the invention is the device for recognizing disruptive particles and the evaluation of the measurement results still continue to improve.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.This problem is solved by the characteristic features of claim 1.

Der Analog/Digitalwandler setzt das Sensorsignal in eine Mehrzahl von Graustufen, z. B. 200 bis 300 Graustufen, um.The analog / digital converter sets the sensor signal in a plurality of grayscale, e.g. B. 200 to 300 shades of gray to.

Nach einer vorteilhaften Ausführungsform weist die Vorrichtung als Kamera eine Flächenkamera, z. B. CCD-Flächenkamera, auf. Be­ vorzugt weist die Flächenkamera eine Einrichtung für eine Kurzzeit­ belichtung auf. Das aufgenommene Bild wird durch eine kurze Be­ lichtungsdauer quasi "eingefroren".According to an advantageous embodiment, the device as a surface camera, z. B. CCD area scan camera. Be The area camera preferably has a device for a short time exposure on. A short Be Glowing time quasi "frozen".

Die Erfindung wird nachfolgend anhand von zeichnerisch darge­ stellten Ausführungsbeispielen näher erläutert.The invention is illustrated below with reference to drawings presented embodiments explained in more detail.

Es zeigt:It shows:

Fig. 1 die erfindungsgemäße Vorrichtung an einer Karde mit Regeleinrichtung und Fig. 1 shows the device according to the invention on a card with control device and

Fig. 2 ein Blockschaltbild mit Analog/Digital­ wandler. Fig. 2 is a block diagram with analog / digital converter.

In Fig. 1 ist eine Karde, z. B. TRÜTZSCHLER EXACTACARD DK, darge­ stellt. Die Vorrichtung zum Erkennen von störenden Partikeln in dem durch die Meßstrecke 50 durchgehenden Faserflor 58 weist als Kamera 12 eine CCD-Flächenkamera und eine Bildverarbeitungseinrich­ tung 14 auf.In Fig. 1 a card, e.g. B. TRÜTZSCHLER EXACTACARD DK, Darge. The device for detecting disruptive particles in the fiber web 58 passing through the measuring section 50 has as the camera 12 a CCD area camera and an image processing device 14 .

Gemäß Fig. 2 sind mit der Kamera 12 der Analog/Digitalwandler 63, der Rechner 15 und die Steuereinrichtung 51 verbunden.Referring to FIG. 2, the analog / digital converter 63, the computer 15 and the controller 51 are connected to the camera 12.

An der Karde (Fig. 1) wird eine mögliche Bewegungsunschärfe durch die Kurzzeitbelichtung vermieden.At the card ( Fig. 1) a possible motion blur due to the short exposure is avoided.
