Abstract

The device comprises a sluice channel (11), where foreign particles (8) are diverted from fiber flow by a pressurized air impulse. A false airflow supports the diverted foreign particles, beginning from the start of the sluice channel to the end of the sluice funnel (5), during transport. The false airflow reaches from the space environment into the sluice channel through a slit opening (9) or more openings arranged on one another.

Description

Seit etwa 1990 gibt es Maschinen zum Entfernen von farbigen Fremdteilen aus Baumwollflocken. Es werden mittels optischer Sensoren Fremdteile erkannt und ausgeschieden.since Around 1990 there are machines for removing colored foreign parts made of cotton flakes. There are foreign parts by means of optical sensors recognized and excreted.

Ein wichtiger Teil solcher Maschinen ist die Vorrichtung zum Ausschleusen der erkannten Fremdteile. Es ist vorgeschlagen worden, den Auffangbehälter völlig von der Umgebungsluft abzuschalten oder mit der Transportluft zu verbinden. Die Anmeldung DE 10347006 schlägt vor, am Ende des Auffangbehälters die ausgeblasenen Fremdteile durch eine Falschluftzuführung abzuführen. Es zeigt sich, daß immer noch Fremdteile am Anfang des Trichters verharren und wieder in den Transportluftstrom gesogen werden können. Aufgabe der Erfindung ist es, den Abtransport der aus dem Transportluftstrom geblasenen Teile weiter zu verbessern. Erfindungsgemäß geschieht dies dadurch, daß nahe der Mündung des Ausschleusekanals in den Transportluftstrom eine sich in etwa der ganzen Arbeitsbreite der Maschine erstreckende Öffnung Falschluft in den Absaugkanal für Fremdfasern einströmen läßt. Diese Falschluft hilft, die Fremdteile in den Absaugtrichter zu transportieren und weiter zum Ende des Trichters, wo die Fremdteile in einem Rohr abgesaugt werden. Um den Falschluftstrom besser in die gewünschte Transportrichtung zu leiten, gibt es ein Umlenkblech, das in etwa 15 mm Entfernung von der Falschluftöffnung angebracht ist. Die Zuluftöffnung kann in ihrem Durchlaß einstellbar sein. Die Öffnung braucht nicht durchgehend sein, sondern kann durch Stege unterbrochen werden, um die Stabilität der Konstruktion zu verbessern. Es können auch mehrer Falschluftöffnungen auch an gegenüberliegenden Seiten des Ausschleusekanals angebracht sein. Es ist besser, die Zugluftöffnung nahe der Fremdfaserausschleuseöffnung in dem Gehäuse anzubringen da die Wirkung direkt einsetzt und weniger Teile in den Transportstrom zurückgelangen.An important part of such machines is the device for discharging the detected foreign parts. It has been proposed to completely shut off the collecting container of the ambient air or to connect with the transport air. The registration DE 10347006 proposes to remove the blown foreign parts by a false air supply at the end of the collection container. It turns out that still foreign parts remain at the beginning of the funnel and can be sucked back into the transport air flow. The object of the invention is to further improve the removal of the blown from the transport air flow parts. According to the invention, this happens in that near the mouth of the discharge channel in the transport air flow extending in about the entire working width of the machine opening false air can flow into the suction channel for foreign fibers. This false air helps to transport the foreign parts in the suction funnel and further to the end of the funnel, where the foreign parts are sucked in a pipe. In order to better direct the false air flow in the desired transport direction, there is a baffle, which is mounted approximately 15 mm away from the false air opening. The supply air opening may be adjustable in its passage. The opening need not be continuous, but can be interrupted by webs to improve the stability of the construction. It can also be mounted on opposite sides of the discharge channel several False air openings. It is better to mount the draft port near the foreign fiber exhaust port in the housing because the effect is immediate and fewer parts return to the transport stream.

1 zeigt schematisch eine Maschine zum Ausschleusen von Fremdteilen mit der Erfindung. Die Fasern durchströmen von links nach rechts die Maschine durch einen breiten Rechteckkanal (1). Durch ein Glasfenster (10) werden die Fasern von einer Kamera (2) beobachtet und bei Feststellung von Fremdteilen werden durch einen Computer (3) Ventile (4) an korrespondierenden Stellen im Faserkanal betätigt und die Fremdteile (8) ausgeblasen. Die Fremdteile gelangen in einen Rechteckkanal (11), wo sie von durch eine Öffnung (9) zuströmende Falschluft weiter in den Trichter (5) gefördert werden. Am Ausgang (6) des Trichters (5) werden Luftstrom und Fasern von einem kleinen Ventilator (7) abgesaugt. 1 schematically shows a machine for discharging foreign parts with the invention. The fibers flow through the machine from left to right through a wide rectangular channel ( 1 ). Through a glass window ( 10 ), the fibers from a camera ( 2 ) and if foreign parts are detected by a computer ( 3 ) Valves ( 4 ) are actuated at corresponding points in the fiber channel and the foreign parts ( 8th ) blown out. The foreign parts enter a rectangular channel ( 11 ), where it passes from through an opening ( 9 ) inflowing secondary air continues into the funnel ( 5 ). At the exit ( 6 ) of the funnel ( 5 ), airflow and fibers from a small fan ( 7 ) sucked off.

Um den Falschluftstrom in die gewünschte Richtung zu lenken, ist ein Umlenkblech (10) im Ausschleusekanal angebracht. Der erste Teil des Ausschleusekanals und die Falschluftzufuhr befinden sich innerhalb des Gehäuses (12).In order to direct the secondary air flow in the desired direction, a baffle ( 10 ) mounted in the discharge channel. The first part of the discharge channel and the false air supply are located inside the housing ( 12 ).
