Abstract

A sensor assembly detects and selectively removes foreign bodies from an air-transported supply of fibres to a textile machine. Following detection, the foreign body impinges on a baffle plate where it is diverted from the main flow of fibre and caught in a trap. The air-flow impinges on the baffle plate at an angle of from 70-160. The slot between the air suction passage and baffle plate is 30-140 mm. The baffle plate edge extends to beneath the suction passage lower edge. The distance between the end of the suction passage and baffle plate is adjustable. Airborne fibres are transported through the passage where they are monitored by a sensor as they move in one direction, before impinging on the baffle plate at 45 and are removed upwards. If the sensor detects a foreign body, a valve is operated above the baffle plate to divert air downwards into a slot and trap.

Description

Zur Detektion und Ausschleusung von Fremdteilen und Fremdfasern aus einem textilen Faserstrom sind in den letzten Jahren viele Vorschläge gemacht worden. Die DE 41 31 188 zeigt eine sehr einfache Form der Ausschleusung in einem rechteckigen Transportkanal. Über die Breite sind Ventile angeordnet, die, falls stromaufwärts ein Fremdteil detektiert wird, an der korrespondierenden Stelle stromabwärts blasen. Die Düsen der Ventile blasen senkrecht zur Strömungsrichtung des Faserluftgemisches und versuchen, die Fremdteile durch einen genau den Düsen gegenüberliegenden Schlitz zu blasen.For the detection and removal of foreign parts and Foreign fibers from a textile fiber stream are in the Many suggestions have been made in recent years. The DE 41 31 188 shows a very simple form of Discharge in a rectangular transport channel. about the width valves are arranged which, if upstream a foreign part is detected at which blow the corresponding point downstream. The nozzles of the valves blow perpendicular to the flow direction of the Fiber air mixture and try to get the foreign parts through a slot exactly opposite the nozzles blow.

So gut diese Anordnung auch beim ersten Eindruck wirkt, hat sie in der Praxis jedoch Nachteile. Die Luftmenge und der Druck, um die Fremdteile aus der Bahn in den gegenüberliegenden Schlitz zu zwingen, sind sehr hoch. Durch die hohe Luftmenge wirbeln die Fremdteile in der Auffangkammer umher und gelangen oft wieder unerwünschter Weise in den Luftstrom zurück.As good as this arrangement looks at first impression, in practice, however, it has disadvantages. The air volume and the pressure to remove the foreign parts from the web in the forcing opposite slot are very high. Due to the high amount of air, the foreign parts swirl in the Catch chamber around and often come back undesirably back into the airflow.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, die mechanisch einfach und zuverlässig die selektive Ausschleusung von Fremdteilen aus einem Faserluftstrom gewährleistet.Task of Invention is to provide a device that the selective mechanically simple and reliable Removal of foreign parts from a fiber air flow guaranteed.

Erfindungsgemäß geschieht dies in der Umlenkung eines Fasertransportkanals. Dies wird anhand der Fig. 1 beschrieben. According to the invention, this takes place in the deflection of a fiber transport channel. This is described with reference to FIG. 1.

Fasern werden durch mindestens eine Öffnungswalze aufgelöst und gelangen in einen bevorzugt rechteckigen Transportkanal, der z. B. die Abmaße von 1600 mm in der Breite und 30 mm in der Höhe haben kann. In diesem Fasertransportkanal Z oder an der Auflösewalze wird mittels einer Kamera K oder einer Reihe von Sensoren der Faserstrom bei einem Beobachtungsfenster S überwacht. Stellt die Sensorik ein Fremteil fest, werden ein oder mehrere Ventile an den korrespondierenden Stellen betätigt und Luft ausgeblasen.Fibers are through at least one opening roller resolved and get into a preferably rectangular Transport channel, the z. B. the dimensions of Can have 1600 mm in width and 30 mm in height. In this fiber transport channel Z or on the opening roller is by means of a camera K or a series of sensors the fiber stream is monitored at an observation window S. If the sensors detect a foreign part, a or several valves at the corresponding points actuated and air blown out.

Die selektive Ausblasung der Fremdfasern erfolgt an einem Prallblech, auf das die Fasern auftreffen. Die Fasern fliegen durch einen Kanal, in dem sie von einem Sensorsystem inspiziert werden. Die Absaugung erfolgt in einer anderen Flugrichtung als die Inspektion der Fasern. Um die Umlenkung der Fasern aus ihrer Flugrichtung zu erleichtern, ist ein Prallblech in den Flugkanal eingebaut, das hilft, die Fasern in die neue Flugrichtung umzulenken. Zum Beispiel ist die Flugrichtung bei der Inspektion oder vor der Umlenkung waagerecht und die Fasern werden senkrecht nach oben abgezogen. Das Prallblech steht dann mit etwa 45° zur Absaugrichtung. Die Fasern treffen auf das Prallblech und werden im Normalfall nach oben hin abgesaugt. Ist von der Sensorik an einer korrespondierenden Stelle ein Fremdmaterial detektiert worden, wird oberhalb des Prallblechs ein Ventil aktiviert, das durch eine Düse geformt einen Luftstrom entlang der Prallblechoberfläche nach unten sendet. Die aufprallenden Fremdteile werden von dem Luftstrom nach unten gerissen und gelangen durch einen Schlitz in den Auffangbehälter. Aus dem Auffangbehälter werden die Fremdteile durch eine Zellenradschleuse in einen Entsorgungsbehälter oder eine Absaugung übergeben. The selective blowing out of the foreign fibers takes place on one Baffle on which the fibers hit. The fibers fly through a channel in which they are from one Sensor system to be inspected. The suction takes place in a different direction of flight than the inspection of the fibers. To redirect the fibers from their flight direction too lighter is a baffle in the flight channel built in, which helps the fibers in the new flight direction redirect. For example, the direction of flight is at Inspection or horizontal before the deflection and the Fibers are pulled vertically upwards. The Baffle is then at about 45 ° to the suction direction. The fibers hit the baffle and are in the Normally sucked upwards. Is from the sensors foreign material at a corresponding point has been detected, will be above the baffle Valve activated which is shaped by a nozzle Airflow down along the baffle surface sends. The impinging foreign parts are from the Airflow torn down and pass through a Slot in the collecting container. From the container the foreign parts through a rotary valve in hand over a disposal container or suction.  

Die Erfindung zeichnet sich durch einen sehr geringen Druckluftverbrauch und eine hohe Sicherheit der Ausschleusung aus.The invention is characterized by very little Compressed air consumption and a high level of security Discharge from.

Die Erfindung wird anhand der Fig. 1 erläutert.The invention is explained with reference to FIG. 1.

Die Fasern werden durch einen Abgsaugkanal A angesaugt. Der Kanal wird an zwei Stellen durch Scheiben S gebildet, durch die Kameras K die Fasern inspizieren. Die Fasern fliegen mit 4 bis 15 m/s durch den Ansaugkanal A. Die Fasern treffen auf ein bezogen auf den Ansaugkanal A in einem Winkel α schräg angeordnetes Prallblech P und werden an diesem in ein Absaugkanalstück B umgeleitet.The fibers are sucked in through an exhaust suction channel A. The channel is formed by discs S in two places, inspect the fibers through cameras K. The fibers fly through intake duct A at 4 to 15 m / s Fibers meet in relation to the intake duct A in an angle α inclined baffle P and are diverted into a suction duct piece B on this.

Wird ein Fremdteil durch die Sensorik entdeckt, so bläst mindestens eines der Ventile V einer Ventilreihe und sendet einen durch eine Düse N geformten Luftstrahl entlang der den Fasern zugewandten Oberfläche des Prallbleches P in Richtung eines Schlitzes H. Der Schlitz wird durch das Prallblech P und das Ende des Ansaugkanals A begrenzt.If a foreign part is detected by the sensor system, it blows at least one of the valves V of a valve series and sends an air jet formed by a nozzle N. along the surface of the fiber facing Baffle plate P in the direction of a slot H. The slot is through the baffle plate P and the end of the intake duct A limited.

Die Fasern und Fremdfasern werden durch den Aufprall gebremst und können daher mit einem relativ geringen Druckluftstrom nach unten in den Schlitz H umgelenkt werden. Die Fremdteile gelangen so in den Zwischenbehälter Z. Der Zwischenbehälter Z ist von der Atmosphäre durch ein Zellenrad W getrennt. Die Fremdteile werden durch das Zellenrad W in einen Auffangbehälter L geschleust.The fibers and foreign fibers are caused by the impact braked and can therefore with a relatively low Compressed air flow deflected down into slot H. become. The foreign parts get into the Intermediate container Z. The intermediate container Z is from the Atmosphere separated by a cellular wheel W. The foreign parts through the cellular wheel W into a collecting container L funneled.
