Description
Fremdfasern in Baumwollgarnen, hervorgerufen durch Stofffetzen in den Baumwollballen, verursachen bedeutende Reklamationen für Spinnereien. Es sind Geräte vorgeschlagen worden, die Baumwolle in der Flocke oder die fertigen Baumwollgarne inspizieren. Zur Kontrolle der Baumwollflocken hat ein Gerät "OPTiSCAN" weite Verbreitung gefunden. Bei diesem Gerät werden in der Reinigungslinie, in einer separaten Maschine, die Flocken über ein Transportband gefördert. In einem engen Spalt sind gegenüber dem Transportband Farbsensoren angeordnet die Farbunterschiede von Fremdteilen erkennen und eine Ausschleusevorrichtung auslösen. Die Erkennung von Fremdfasern im fertigen Garn, erfolgt im Spulprozess. Hierbei werden mit einem schwarzweiss Sensor die Garne beurteilt und ggf. das dunklere Garnstück herausgeschnitten.foreign fibers in cotton yarns caused by fabric rags in the cotton bales, cause significant complaints for spinners. There are devices proposed the cotton in the flake or the finished cotton yarns inspect. To control the cotton flakes has a device "OPTiSCAN" widely used found. In this device be in the cleaning line, in a separate machine, the Flakes over promoted a conveyor belt. In a narrow gap are opposite to the Conveyor belt color sensors arranged the color differences of foreign parts recognize and trigger an ejection device. The detection of foreign fibers in the finished yarn, takes place in the winding process. Here are with a black-and-white sensor evaluates the yarns and if necessary cut out the darker piece of yarn.

Um die störenden Partikel auch im Inneren der Faserschicht zu erfassen und die Ermittlung und differenzierte Auswertung von Trashpartikeln, Nissen, Schalennissen, Noppen u. dgl. zu ermöglichen, wird ein dünner Faserflor gebildet, erfasst der Sensor schrittweise jeden störenden Einzelpartikel und werden mittels einer Auswerteinrichtung für jeden Einzelpartikel spezifische Kenngrößen, z. B. Grauwerte ermittelt, aufgrund der Kenngrößen die Einzelpartikel anhand eines Vergleichs klassifiziert, z. B. nach Typ, Form, Größe und die Einzelpartikel gezählt.Around the disturbing ones Particles can also be detected inside the fiber layer and the determination and differentiated evaluation of trash particles, nits, shell notes, Pimples u.

Für die optischen Messungen werden vorteilhafterweise mehrere optische Sensoren verwendet, die über die Vliesbreite verteilt angeordnet sind und die über einen langsamen Multiplexer mit einer einzigen elektronischen Schaltung zur Weiterverarbeitung der Signale zusammen geschaltet sind.For the optical Measurements advantageously several optical sensors are used, over the Fleece width are distributed and distributed over a slow multiplexer with a single electronic circuit for further processing of the Signals are switched together.
Die Methoden sind mit deutlichen Investitionskosten verbunden und sind nicht einfach in vorhandene Anlagen zu integrieren.The Methods are associated with significant investment costs and are not easy to integrate into existing facilities.
Aufgabe der Erfindung ist es eine preiswerte und leicht zu installierende Hilfe zur Bekämpfung der Fremdfasern in der Spinnerei zu schaffen.task The invention is a cheap and easy to install Help to combat to create foreign fibers in the spinning mill.
Zur Erkennung von Fremdfasern ist es notwendig, dass die Baumwollballen zu Flocken geöffnet werden, damit die Fremdfaserfetzen sichtbar sind. Es ist notwendig eine große durch Farbsensoren zu beobachtende Oberfläche zu schaffen.to Detection of foreign fibers, it is necessary that the cotton bales opened to flakes so that the foreign fiber shreds are visible. It is necessary a big to create surface to be observed by color sensors.
Erfindungsgemäß wird die Fremdfaserdetektion dadurch gelöst, dass Baumwolle und Fremdfasern um mindestens eine Öffnungswalze gefördert werden, die mit Garnitur, Stiften oder "Nasen" versehen ist und Farbsensoren in etwa achsparallel in einer oder mehreren Reihen gegenüber dem Umfang der Walze angeordnet sind. Der Abstand der Sensorobjektive von dem Walzenumfang darf nicht zu gross gewählt werden, da sonst die Objektive durch die Baumwolle nicht mehr vom Staub freigewischt werden. Ein Abstand von 20 mm zu dem Spitzenumfang sollte bei Plazierung in der Nähe der Trommel nicht überschritten werden. Lediglich bei einer Positionierung der Sensorreihe im Deflektor kann der Abstand zur Trommel größer gewählt werden, da die Flocken durch die Fliehkraft in Richtung Deflektor fliegen und an dem Deflektor entlang in den Absaugkanal "C" rutschen.According to the invention, the foreign fiber detection is achieved in that cotton and foreign fibers are promoted by at least one opening roller, which is provided with clothing, pins or "noses" and color sensors approximately parallel to the axis in one or more rows with respect to the circumference the roller are arranged. The distance of the sensor lenses from the roll circumference must not be too large, otherwise the lenses will no longer be wiped free by the dust. A distance of 20 mm from the tip circumference should not be exceeded when placed near the drum. Only with a positioning of the sensor row in the deflector, the distance to the drum can be chosen larger, since the flakes fly through the centrifugal force in the direction of the deflector and slip along the deflector in the suction channel "C".
Anhand
Die Fasern werden durch die Stifte entlang von Ausscheidemessern "K" gezogen, oder entlang von Mulden "M". Es ist möglich die Farbsensoren "S" in einer Mulde einzubauen. Die Baumwolle putzt die oder das Objektiv beim Vorbeitransport immer frei. Vorteilhaft kann die Sensoranordnung in dem Luftleitblech gewählt werden, das die Luft, zum Abtransport der Fasern von der Walzoberfläche, leitet. Diese Position erlaubt eine leichte Montage und gute Zugänglichkeit. An einer Aushebekante "N" staut sich die mit der Walze rotierende Luft und hebt die restlichen Fasern von den Stiften ab. Fasern und Fremdfasern gelangen in eine Absaugleitung "C" in der eine Ausschleusevorrichtung "F", angebracht ist. Werden durch die Sensoren Fremdfasern aufgrund eines Farb- oder Helligkeitsunterschiedes zur Baumwolle festgestellt, wird demnach die Ausschleusvorrichtung betätigt und etwas Baumwolle mit den Fremdfasern ausgeschleust. Die Ausschleusung kann in bekannter Weise durch eine Umschaltklappe von "A" "Gutmaterial" zu "B" kontaminiertes Material erfolgen.The Fibers are drawn through the pins along "K" or "M" hollows. It is possible to install color sensors "S" in a trough. The cotton cleans the lens or the lens during the transport always free. Advantageous if the sensor arrangement can be selected in the air guide plate, which directs the air to remove the fibers from the rolling surface. This position allows easy installation and good accessibility. At a Aushebekante "N" dams up with the Roll rotating air and lift the remaining fibers off the pins from. Fibers and foreign fibers enter a suction line "C" in which a discharge device "F" is attached. Be through the sensors Foreign fibers due to a difference in color or brightness Cotton detected, therefore, the discharge device is actuated and some cotton with the foreign fibers discharged. The discharge can be done in a known manner by a switching flap of "A" "good material" to "B" contaminated material.
Durch die Anordnung der Sensoren so, dass sie auf die Oberfläche der Trommel sehen können, ist eine große Oberfläche zur gründlichen Inspektion der Baumwolle ermöglicht.By the arrangement of the sensors so that they touch the surface of Can see drum, is a big one surface for thorough Inspection of cotton allows.
Die Trommel transportiert die Fasern mechanisch so, dass nicht die Gefahr von Verstopfungen, wie bei Inspektionssystemen die im Luftstrom arbeiten, gegeben ist. Die vorgeschlagene Vorrichtung benötigt keine neue Maschine und kann leicht in vorhandene Reinigungszüge eingebaut werden.The Drum transports the fibers mechanically so that not the danger of blockages, as in inspection systems in the air stream work, is given. The proposed device does not need any new machine and can be easily installed in existing cleaning trains become.
