Description

Fremdfasern in Baumwollgarnen, hervorgerufen durch Stoffetzen 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. Beide Methoden sind mit deutlichen Investitionskosten verbunden und sind nicht einfach in vorhandene Anlagen zu integrieren. Aufgabe der Erfindung ist es eine preiswerte und leicht zu installierende Hilfe zur Bekämpfung der Fremdfasern in der Spinnerei zu schaffen.Foreign fibers in cotton yarn, caused by rags in the Cotton bales cause significant complaints for spinning mills. There are Devices have been suggested to use the cotton in the flake or the finished one Inspect cotton yarns. To control the cotton flakes has a device "OPTiSCAN" found widespread use. With this device in the Cleaning line, in a separate machine, the flakes on a conveyor belt promoted. Are in a narrow gap opposite the conveyor belt Color sensors arranged to recognize the color differences of foreign parts and trigger a discharge device. The detection of foreign fibers in the finished yarn, takes place in the winding process. Here, with a black and white Sensor evaluates the yarns and cut out the darker piece of yarn if necessary. Both methods are associated with significant investment costs and are not easy to integrate into existing systems. The object of the invention is inexpensive and easy to install help to fight foreign fibers in to create 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 detect foreign fibers, it is necessary that the cotton bales are closed Flakes are opened so that the foreign fiber scraps are visible. It is necessary a large surface to be observed by color sensors create.

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 den 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 foreign fiber detection is solved in that cotton and foreign fibers are conveyed around at least one opening roller Set, pins or "noses" is provided and color sensors approximately axially parallel arranged in one or more rows opposite the circumference of the roller are. The distance between the sensor lenses and the roller circumference must not be too great should be selected, otherwise the lenses will no longer be from the cotton Dust can be wiped free. A distance of 20 mm to the tip circumference should be when placed near the drum. Only at Positioning the sensor row in the deflector can change the distance to the drum be chosen larger, because the flakes due to the centrifugal force in the direction of the deflector fly and slide along the deflector into the suction channel "C".  

Anhand Fig. 1 wird eine Ausführungsform erläutert. Die Fasern gelangen durch einen Schacht "L" zu Zuführwalzen "Z", die die Fasern an die Oberfläche der Walze "W" führen. Die Walze "W" kann z. B. einen Durchmesser von 350 mm haben und mit 500 u/min rotieren. Die Faserbüschel werden von den Stiften oder Hacken der Öffnungswalze geöffnet und Baumwollflocken und Fremdfasern (Stoffstücke) werden von der Trommel am Umfang transportiert. Es können auch mehrere Öffnungswalzen hintereinander gebaut sein, wobei sich eine der ersten Walzen für die Erfassung, wegen der geringeren Umfangsgeschwindigkeit, am besten eignet. Die Oberfläche der Walzen ist vorzugsweise hell, z. B. Aluminium.An embodiment is explained with reference to FIG. 1. The fibers pass through a shaft "L" to feed rollers "Z" which guide the fibers to the surface of the roller "W". The roller "W" can, for. B. have a diameter of 350 mm and rotate at 500 rpm. The tufts of fibers are opened by the pins or hooks of the opening roller, and cotton flakes and foreign fibers (pieces of fabric) are transported around the circumference by the drum. Several opening rollers can also be built one behind the other, one of the first rollers being best suited for the detection because of the lower peripheral speed. The surface of the rollers is preferably light, e.g. B. aluminum.

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 the knives "K" or along troughs "M". It is possible to use the color sensors "S" in a trough to install. The cotton cleans the lens or lens as it is transported past always free. The sensor arrangement in the air baffle can advantageously be selected which directs the air to remove the fibers from the rolling surface. This position allows easy assembly and good accessibility. At a Lifting edge "N" builds up the air rotating with the roller and lifts it remaining fibers from the pins. Fibers and foreign fibers get into one Suction line "C" in which a discharge device "F" is attached. Become through the sensors foreign fibers due to a color or Difference in brightness compared to cotton is determined accordingly Discharge device actuated and some cotton with the foreign fibers diverted. The discharge can in a known manner by a Switchover flap from "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 arranging the sensors so that they hit the surface of the drum can see is a large surface for thorough inspection of the 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 mechanically transports the fibers so that there is no risk of Blockages, as with inspection systems that work in the air flow, exist is. The proposed device does not require a new machine and can can be easily installed in existing cleaning trains.
