Abstract

An installation is for detection of differently-coloured fibres in the fibre current between the card doffer and the rotating plate in cards. At least at two points during the course of the fibre transport, colour sensors measure colour deviation from a preset 'good' value and when deviation limits are exceeded, fibre transport into the can is interrupted.

Description

Fremdfasern in Bauwollgarnen, 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 Game 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 assesses the game and, if necessary, cut out the darker piece of yarn. 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.

Erfindungsgemäß wird dies durch die Installation von mindestens 2 Farberkennungssensoren zwischen Kardendoffer und Dreheinrichtung an der Kanne erwirkt. Die Farbsensoren überwachen den Faserstrom und lösen bei Farbabweichung einen Stillstand aus. Die Farbsensoren sind üblicherweise oberhalb des Drehtellers am Kannenstock angebracht und ersetzten die dort übliche Reflexionslichtschranke zur Überwachung ob das Kardenband gerissen ist. Sie lösen wie die Lichtschranke einen Stop der Karde aus. Zur besseren Erkennung der Fremdfasern sind die Farbsensoren gegenüber versetzt angeordnet. Bei der Fremdfasererkennung hat sich gezeigt, daß viele Fremdfasern in der normalen Reinigungslinie ausgeschieden werden. Kleine Stoffetzen die durch die Reinigungslinie zur Karde gelangen, werden dort zu Fasern aufgelöst und sind meist als Farbstreifen von 5 bis 50 cm Länge im Kardenband sichtbar. Die Farbfasern sind mit normalen Fasern zusammen in einem Band gefaßt, doch meistens so deutlich, daß sie gut erkannt werden können. Sind die Fremdfasern erkannt, wird die Karde genau wie bei Bandbruch abgeschaltet.According to the invention, this is achieved by installing at least 2 Color detection sensors between card holder and rotating device on the Kanne effects. The color sensors monitor the fiber flow and solve Color deviation from a standstill. The color sensors are common attached to the jug stick above the turntable and replaced them there Usual reflection light barrier for monitoring whether the card sliver is torn is. Like the light barrier, they trigger a card stop. For better Detection of foreign fibers is offset from the color sensors arranged. Foreign fiber detection has shown that many foreign fibers be eliminated in the normal cleaning line. Little rags through the cleaning line to the card, fibers are dissolved there and are usually visible as color strips of 5 to 50 cm in length in the card sliver. The colored fibers are combined in a band with normal fibers, but usually so clearly that they can be easily recognized. Are the foreign fibers detected, the card is switched off in the same way as in the case of a broken belt

Die Farbsensoren können durch einen "Lernzyklus" die "richtige" Farbe der Baumwolle einlesen und mit der laufenden Produktion vergleichen. Es sind nur wenige Sensoren zur Auswertung notwendig und die Einrichtung kann schnell und einfach an vorhandenen Karden installiert werden.The color sensors can use a "learning cycle" to determine the "correct" color of the Read in the cotton and compare it with the current production. It is only Few sensors necessary for evaluation and the setup can be done quickly and simply installed on existing cards.
