Description
Die Erfindung betrifft eine Vorrichtung in der Spinnereivorbereitung, Ginnerei o. dgl. zum Erkennen von Fremdstoffen in oder zwischen Fasermaterial, insbesondere Baumwolle, mit einem Präsentationskanal, der mittels wenigstens zweier nacheinander angeordneter Detektoreinrichtungen (Sensoranordnungen) zum Erkennen eines Fremdstoffes beaufschlagbar ist und mit einem pneumatischen Fördermittel zum Durchleiten des Fasermaterials durch den Präsentationskanal, bei der eine erste Detektoreinrichtung (Sensoranordnung) wenigstens eine elektronische Kamera mit Farbsensorik aufweist und eine weitere Detektoreinrichtung (Sensoranordnung) vorhanden ist, die im Bereich von Ultraviolett arbeitet.The Invention relates to a device in spinning preparation, Ginnerei o. The like. For detecting foreign substances in or between Fiber material, in particular cotton, with a presentation channel, by means of at least two successively arranged detector devices (Sensor arrangements) for detecting a foreign substance acted upon is and with a pneumatic conveyor for passing of the fiber material through the presentation channel at which a first detector device (sensor arrangement) at least one electronic Camera with color sensor and having a further detector device (Sensor array) is present, which is in the range of ultraviolet is working.
In Spinnereivorbereitungsanlagen und Ginnereien ist es wichtig, Fremdfasern oder andere Fremdteile aus Baumwolle zu entfernen, insbesondere wenn diese sich durch eine andere Farbe von der Baumwolle unterscheiden. Ein weiteres Problem beim Betrieb von optisch arbeitenden Fremdfasern- oder Fremdteilausscheidern in Spinnereivorbereitungsmaschinen und Ginnereien für Baumwolle oder Chemiefasern ist, dass diese helle oder transparente Kunststoffe (wie z. B. Verpackungsfolien oder Verpackungsgewebe aus Polyethylen oder Polypropylen), wegen des geringen optischen Kontrastes nur unzureichend oder gar nicht erkennen können.In Spinning preparation plants and ginnings it is important to use foreign fibers or to remove other foreign parts of cotton, in particular if they are different from cotton by a different color. Another problem with the operation of optically operating Fremdfasern- or Foreign part separators in spinning preparation machines and ginning plants for cotton or chemical fibers is that these bright or transparent plastics (such as packaging films or packaging fabrics) made of polyethylene or polypropylene), because of the low optical Contrast only insufficiently or not at all.
Bei
einer bekannten Vorrichtung (
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere auf konstruktiv einfache Art platzsparend in eine Produktionslinie einbaubar ist und eine wirksame Erkennung von weißen und/oder transparenten Kunststoffen sowie von farbigen Fremdstoffen ermöglicht.Of the The invention is based on the object, a To provide device of the type described above, which the avoid mentioned disadvantages, in particular to constructive simple way to save space in a production line can be installed and effective detection of white and / or transparent Plastics and colored foreign substances.
Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.The Solution to this problem is done by the characterizing Features of claim 1.
Erfindungsgemäß ist die Erkennung mit Farbsensoren und mit UV-Licht kombiniert mit der Erkennung mit polarisiertem Licht, ohne dass dabei für die Erkennung mit UV-Licht und mit polarisiertem Licht wesentliche Komponenten wie Kameras, Inspektionsräume, Glaskanäle, oder Auswertekomponenten doppelt vorhanden sein müssen und ohne dass eine gegenseitige Störung der beiden Erkennungsverfahren mit UV-Licht und polarisiertem Licht stattfindet. Diese Anordnung konzentriert die notwendigen Komponenten auf engstem Raum und spart dadurch Bauraum. Es liegt eine kombinierte Anwendung von unterschiedlichen Wellenlängen (sichtbares Licht/UV-Licht) und unterschiedlichen Polarisationszuständen (polarisiert/unpolarisiert) vor. Es wird nur ein Bild aufgenommen, welches gleichzeitig mit beiden Lichtquellen beleuchtet wird. Ein weiterer Vorteil besteht in der Möglichkeit der gleichzeitigen Beleuchtung und Bildaufnahme, so dass zum einen keine Konvergenz der beiden Komponenten nachträglich erzeugt und keine zeitliche Auflösungsreduktion aufgrund doppelter Bildaufnahme erfolgt. Gemäß der Erfindung wird (ohne sichtbare Spektralanteile) unpolarisiert beleuchtet (Auflicht) und mit sichtbarem Licht polarisiert durchleuchtet (Durchlicht). In dieser Kombination entsteht ein Bild, welches ohne schalten/blitzen der Beleuchtung von einer Kamera aufgenommen werden kann und somit auch beide Effekte durch Veränderung des Polarisationszustandes als auch durch Fluoreszenz beinhaltet. Auf diese Weise werden auch solche Verpackungsmaterialien und Kunststoffabfälle in Fasermaterialien detektiert, welche nur mit UV-Licht oder nur mit polarisiertem Licht erkennbar sind. Bei bestimmten Chemiefasern und auch bei mit optischen Aufhellern hergestellten Kunststoffen, wird das aufgestrahlte UV-Licht durch einen Fluoreszenzeffekt in sichtbare Wellenlängen gewandelt. Dieses ist dann durch normale Kamerasysteme detektierbar. Die Kamera ist nicht empfindlich für das aufgestrahlte UV-Licht. Eine Detektion erfolgt erst dann, wenn durch Fluoreszenzeffekte das UV-Licht in sichtbares Licht gewandelt wird. Dadurch gelingt es, eine möglichst umfangreiche Sortenvielfalt von Kunststofffremdteilen zu detektieren. Außerdem werden auch dichte oder dicke Kunststoffreste oder Kunststoffsorten, die den Polarisationszustand des durchstrahlten polarisierten Lichtes nicht verändern, erkannt.According to the invention the detection with color sensors and with UV light combined with the Detection with polarized light, without affecting the Detection with UV light and with polarized light essential components like cameras, inspection rooms, glass ducts, or Evaluation components must be present twice and without that a mutual interference of the two recognition methods with UV light and polarized light takes place. This arrangement concentrates the necessary components in a confined space and thereby saves Space. It is a combined application of different Wavelengths (visible light / UV light) and different Polarization states (polarized / unpolarized). Only one picture is taken, which is simultaneous with both Light sources is illuminated. Another advantage is in the Possibility of simultaneous illumination and image acquisition, so that, on the one hand, no convergence of the two components subsequently generated and no temporal resolution reduction due double image acquisition takes place. According to the invention is illuminated (without visible spectral components) unpolarized (incident light) and polarized with visible light (transmitted light). In this combination creates an image, which without switching / flashing the lighting can be picked up by a camera and thus also both effects by changing the polarization state as well as by fluorescence. This way too such packaging materials and plastic waste in Fiber materials detected, which only with UV light or only with polarized light are recognizable. For certain chemical fibers and also in plastics produced with optical brighteners, the radiated UV light is reflected by a fluorescence effect in visible wavelengths changed. This is then through normal camera systems detectable. The camera is not sensitive for the irradiated UV light. A detection takes place only when fluorescence effects the UV light in visible Light is converted. This succeeds, as possible to detect a wide variety of varieties of plastic parts. In addition, dense or thick plastic residues or plastic types, the polarization state of the transmitted polarized light do not change, recognized.
