Abstract

An installation is for detecting differently coloured fibres in the fibre current between the can and the drawing system of the first drawing passage in cotton spinning plants. Any colour deviation from a preset 'good' value is measured by sensors at at least two points of the fibre transport stretch. In the event of deviation limits being exceeded, fibre transport is interrupted.

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.

Erfindungsgemäß wird dies durch die Installation von mindestens 2 Farberkennungssensoren zwischen Kanne und Streckwerk der 1. Streckpassage erwirkt. Die Farbsensoren überwachen den Faserstrom und lösen bei Farbabweichung einen Stillstand aus. Die Farbsensoren sind üblicherweise oberhalb des Einlauftisches am Streckeneinlauf angebracht. Sie lösen wie eine Bandüberwachung einen Stop der Strecke aus. Zur besseren Erkennung der Fremdfasern sind auch Farbsensoren unterhalb 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 Strecke genau wie bei Bandbruch abgeschaltet.According to the invention, this is achieved by installing at least 2 Color detection sensors between the can and drafting system of the 1st draft passage it acts. The color sensors monitor the fiber flow and solve Color deviation from a standstill. The color sensors are common Attached above the infeed table at the line inlet. You solve like one Belt monitoring a stop of the route. For better detection of the Foreign fibers are also arranged below color sensors. In the Foreign fiber detection has shown that many foreign fibers in the normal Cleaning line to be excreted. Little rags through the Cleaning line to the card, are broken down into fibers and are there mostly visible as strips of color from 5 to 50 cm in length in the card sliver. The Colored fibers are bundled together with normal fibers, but usually so clearly that they can be easily recognized. Are the foreign fibers detected, the route is switched off just like in the event of a belt break.

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 Strecken 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 can be easily installed on existing routes.
