Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen von verdichtetem Garn, mit mindestens einem Streckwerk zum Verziehen einer Faserlunte, mit mindestens einer Saugvorrichtung zum Verdichten der Faserlunte mittels Saugluftströmung in einer Faserbündelungszone, mit mindestens einer Verdreheinrichtung und mit einer Einrichtung zum Erfassen der Saugluftströmung.The invention relates to a device for producing compressed Yarn, with at least one drafting device for drawing a fiber sliver, with at least one suction device for compressing the fiber sliver by means of suction air flow in a fiber bundling zone, with at least one twisting device and with a device for detecting the suction air flow.

Als Stand der Technik ist bereits eine derartige Vorrichtung bekannt (DE 198 56 121 A1), bei welcher zum Erfassen der Saugluftströmung beispielsweise ein Messrohr Anwendung findet, welches direkt in das Gehäuse eines Riemchenkäfigs führt, der Teil der Saugvorrichtung ist. Es besteht auch die Möglichkeit eines Einsatzes von Messfühlern, z. B. Hitzedrahtanemometer.Such a device is already known as prior art (DE 198 56 121 A1), in which, for example, to detect the suction air flow Measuring tube is used, which is directly in the housing of an apron cage leads, which is part of the suction device. There is also the possibility of one Use of sensors, e.g. B. Hot wire anemometer.

Gegenüber diesem bekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine weitere Möglichkeit zu schaffen, auf einfache Weise die Funktion der Saugluftströmung zu überwachen.The object of the invention is in relation to this known prior art based on another way to easily create the function monitor the suction air flow.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Einrichtung zum Erfassen der Saugluftströmung gemäß den Merkmalen im kennzeichnenden Teil des Anspruchs 1 ausgebildet ist. Hierdurch wird auf einfache Weise ermöglicht, den Wegfall oder ein Absinken der Saugluftströmung sofort erkennbar zu machen.This object is achieved in that the device for Detect the suction air flow according to the features in the characterizing part of claim 1 is formed. This enables in a simple manner make the loss or decrease of the suction air flow immediately recognizable.

Ein wesentliches unterscheidendes Merkmal zum Stand der Technik nach der DE 198 56 121 ist, dass dort der Saugluftstrom im geschlossenen Strom (im Rohr), bei der Erfindung im offenen Bereich überwacht wird. An essential distinguishing feature of the prior art according to DE 198 56 121 is that there the suction air flow in the closed flow (in the pipe), is monitored in the invention in the open area.

Bei einer Vorrichtung, bei der die Einrichtung zum Erfassen der Saugluftströmung mit einer Auswerteeinheit verbunden ist, besteht erfindungsgemäß die Möglichkeit, dass bei Funktionsstörung der Saugluftströmung die geänderte Position der Klappe durch einen mit der Auswerteeinheit verbundenen Taster erfassbar ist. Dieser Taster kann beispielsweise als Fotozelle, als Magnetfühler, als elektrischer Kontaktfühler, als pneumatisches oder als mechanisches Element ausgebildet sein.In a device in which the device for detecting the suction air flow is connected to an evaluation unit, according to the invention Possibility that in the event of malfunction of the suction air flow, the changed position the flap can be detected by a button connected to the evaluation unit is. This button can be used, for example, as a photo cell, as a magnetic sensor electrical contact sensor, as pneumatic or as mechanical element be trained.

Bei einer Vorrichtung, bei welcher die Saugvorrichtung einen oberhalb der Faserbündelungszone angeordneten Saugschuh aufweist, welcher von einem um eine Oberwalze eines Lieferwalzenpaares geführten, perforierten Riemchen zumindest teilweise umschlungen ist, ergibt sich eine vorteilhafte Lösungsmöglichkeit dadurch, dass die Klappe im Bereich des Saugschuhes unterhalb der Faserbündelungszone angeordnet ist. Alternativ besteht auch die Möglichkeit, dass die Saugvorrichtung unterhalb und die Klappe oberhalb der Verdichtungszone angeordnet ist.In a device in which the suction device is located above the fiber bundling zone arranged suction shoe, which from one to one At least the top roller of a pair of perforated perforated aprons is partially entwined, an advantageous solution arises from that the flap in the area of the suction shoe below the fiber bundling zone is arranged. Alternatively, there is also the possibility that the suction device below and the flap above the compression zone is.

Weiterhin kann die Drehachse quer oder schräg zur oder in Laufrichtung der Faserlunte liegen. Hierbei kann in einer Ausführungsform die Klappe mit einer deren Position kennzeichnenden Signalfläche versehen sein, an welcher die Stellung der Klappe leicht und auch aus größerem Abstand erkennbar ist.Furthermore, the axis of rotation can be transverse or oblique to or in the direction of travel Fiber sliver lie. In one embodiment, the flap can have a their position characterizing signal area at which the position the flap is easy and recognizable even from a distance.

Eine alternative Lösung besteht darin, dass die Klappe mit einem elektrischen Kontakt verbunden ist, welcher in Abhängigkeit von der Klappenstellung einen Signalstromkreis öffnet bzw. schließt.An alternative solution is to use an electric flap Contact is connected, which depending on the flap position Signal circuit opens or closes.

In weiterer Ausgestaltung der Erfindung kann bei Funktionsstörung der Saugluftströmung die aus dem Bereich der Faserbündelungszone weggeschwenkte Klappe an einem Anschlag anliegen, wobei der mit der Drehachse verbundene AnschlagTeil des Signalstromkreises ist. In a further embodiment of the invention, the suction air flow can malfunction the flap pivoted away from the area of the fiber bundling zone abut a stop, the stop part connected to the axis of rotation of the signal circuit is.

Das für die Schwenkbewegung maßgebende Gewicht der Klappe kann erfindungsgemäß durch ein Gegengewicht zum Teil ausgeglichen werden. Hierbei kann das Gegengewicht veränderbar, beispielsweise verschiebbar sein, um das Gewicht an die Höhe der Saugluftströmung oder an die gewünschte Empfindlichkeit der Überwachung anpassen zu können.The weight of the flap which is decisive for the pivoting movement can be according to the invention can be partially offset by a counterweight. in this connection the counterweight can be changed, for example displaceable, by the Weight depending on the height of the suction air flow or the desired sensitivity to be able to adapt to the surveillance.

Falls kein Anschlag in Form des Kontaktes vorgesehen ist, ist ein Anschlag anderer Art erforderlich, um zu verhindern, dass die Klappe zu weit nach unten fällt und sich aus dem Wirkungsbereich der Saugluftströmung begibt.If no stop in the form of the contact is provided, another stop is Type required to prevent the flap from falling too far and comes out of the effective range of the suction air flow.

Die Klappe kann quadratisch, rechteckig, rund, oval oder in beliebiger Form ausgebildet sein, wobei es jedoch wichtig ist, dass sie leicht und schwenkbar gelagert ist, so dass sie auch durch geringen Saugzug verschwenkt werden kann.The flap can be square, rectangular, round, oval or in any shape be trained, but it is important that they are easily and pivotally mounted is so that it can be swiveled even with a slight suction.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben.The invention is illustrated below with the aid of one in the drawing Embodiment described in more detail.

In der Zeichnung zeigen:

Fig. 1 und 2 zeigen teilweise eine Vorrichtung zum Herstellen von verdichtetem Garn, mit mindestens einem nicht näher dargestellten Streckwerk zum Verziehen einer Faserlunte 1 und mit mindestens einer Saugvorrichtung 4 zum Verdichten der Faserlunte 1 mittels Saugluftströmung in einer Faserbündelungszone F. In Faserlaufrichtung hinter dieser Saugvorrichtung 4 befindet sich eine nicht näher dargestellte Verdreheinrichtung, beispielsweise eine Ringspinneinrichtung. Weiterhin weist die Vorrichtung eine Einrichtung 10 zum Erfassen der Saugluftströmung auf, welche mit einer Auswerteinheit 20 verbunden ist.1 and 2 partially show a device for producing compressed Yarn, with at least one drafting device, not shown, for warping a fiber sliver 1 and with at least one suction device 4 for compacting the fiber sliver 1 by means of suction air flow in a fiber bundling zone F. In the fiber running direction behind this suction device 4 is a not shown Rotating device, for example a ring spinning device. Farther the device has a device 10 for detecting the suction air flow which is connected to an evaluation unit 20.

Die Saugvorrichtung 4 besitzt oberhalb der Faserbündelungszone F einen Saugschuh 7, welcher von einem um eine Oberwalze 8 eines Lieferwalzenpaares 26 geführten, perforierten Riemchen 16 zumindest teilweise umschlungen ist.The suction device 4 has a suction shoe above the fiber bundling zone F. 7, which of one around an upper roller 8 of a pair of delivery rollers 26 guided, perforated straps 16 is at least partially wrapped.

Aus Fig. 2 geht diese Perforierung des Riemchens 16 hervor, welche aus einer Anzahl in Laufrichtung der Faserlunte 1 hintereinander liegender, kleiner Öffnungen, z.B. neben - und/oder hintereinander besteht.2 shows this perforation of the strappy 16, which consists of a Number of small openings one behind the other in the running direction of the fiber sliver, e.g. exists next to and / or in a row.

Der Saugschuh 7 ist über eine Saugleitung 28 mit einer nicht näher dargestellten Saugeinheit verbunden. Mit Hilfe der Saugvorrichtung 4 wird damit eine Saugluftströmung erzielt, welche zur Verdichtung der Faserlunte 1 dient. Nach Verlassen des Lieferwalzenpaares 26 wird die so bearbeitete Faserlunte durch die Verdreheinrichtung weiter bearbeitet.The suction shoe 7 is connected via a suction line 28 to a not shown Suction unit connected. With the help of the suction device 4 is a suction air flow achieved, which serves to compress the fiber sliver 1. After leaving of the pair of delivery rollers 26, the fiber sliver thus processed is turned by the twisting device further edited.

Die Einrichtung 10 zum Erfassen der Saugluftströmung ist als eine um eine Drehachse 15 schwenkbare Klappe 12 ausgebildet, welche bei Funktionsstörung der Saugluftströmung die Auswerteeinheit 20 aktiviert. Die Klappe 12 ist dementsprechend im Bereich des Saugschuhs 7 unterhalb der Faserbündelungszone F angeordnet, wobei die Drehachse 15 quer zur Laufrichtung der Faserlunte 1 liegt.The device 10 for detecting the suction air flow is as one about an axis of rotation 15 pivotable flap 12 formed, which in the event of malfunction Suction air flow activated the evaluation unit 20. The flap 12 is accordingly arranged in the area of the suction shoe 7 below the fiber bundling zone F, wherein the axis of rotation 15 is transverse to the direction of the fiber sliver 1.

Es besteht auch die nicht näher dargestellte Möglichkeit, die Drehachse in Laufrichtung der Faserlunte 1 seitlich neben der Perforationsspur anzuordnen.There is also the possibility, not shown, of the axis of rotation in the running direction to arrange the fiber sliver 1 to the side of the perforation track.

Wie aus Fig. 1 und 2 erkennbar, ist die Klappe 12 mit einem Gegengewicht 24 versehen, welches vorzugsweise zur Anpassung der Klappe 12 an die Höhe des Saugluftstromes veränderbar, beispielsweise verschiebbar ist. As can be seen from FIGS. 1 and 2, the flap 12 has a counterweight 24 provided which is preferably to adjust the flap 12 to the height of the Suction air flow is changeable, for example displaceable.

In der in Fig. 1 dargestellten Arbeitsstellung liegt die Klappe 12 an einem Anschlag 23 an, welcher zum Begrenzen der Klappenschwenkung im Bereich der Faserbündelungszone F dient.In the working position shown in FIG. 1, the flap 12 lies against a stop 23, which is used to limit the flap pivoting in the area of the Fiber bundling zone F is used.

Aus Fig. 1 ist darüber hinaus erkennbar, dass ein weiterer Anschlag 22 Anwendung findet, welcher über einen Signalstromkreis 18 mit der Drehachse 15 verbunden ist. Im Signalstromkreis 18 befindet sich eine Alarm- und/oder Abstelleinrichtung 20.From Fig. 1 it can also be seen that a further stop 22 application finds, which is connected via a signal circuit 18 to the axis of rotation 15 is. An alarm and / or shutdown device is located in the signal circuit 18 20th

Die Signalfläche könnte als seitliche Fahne an der Klappe 12 ausgebildet sein, die seitlich neben der Ausgangsunterwalze nach vorn ragt und bei hochgeschwenkter Klappe von vorn leicht sichtbar ist.The signal area could be designed as a lateral flag on the flap 12 protrudes to the side next to the output lower roller and with the swiveled up Flap is easily visible from the front.

Die Klappe 12 ist leicht ausgebildet und leicht schwenkbar in der Drehachse 15 gelagert, so dass sie auch durch geringe Saugluftströmung verschwenkbar ist. Ihr Schwenkweg, d. h. der Winkel α ist durch die beiden Anschläge 22 und 23 begrenzt, und zwar einmal in abgeschwenkter Stellung (gestrichelt dargestellt), um sie in einem Bereich zu halten, aus dem sie nach Beheben einer Funktionsstörung der Saugluftströmung durch den erneuten Saugzug angesaugt werden kann und zum Weiteren in der in Fig. 1 dargestellten Stellung, damit sie den Zutritt des verdichteten Luftstroms, d. h. der Saugluftströmung, nicht behindert.The flap 12 is designed to be light and can be pivoted easily in the axis of rotation 15 stored so that it can be pivoted even by low suction air flow. you Swivel path, d. H. the angle α is limited by the two stops 22 and 23, once in the pivoted position (shown in dashed lines) to to keep them in an area from which they can resolve a malfunction the suction air flow can be sucked in by the renewed suction and furthermore in the position shown in FIG. 1, so that they compact the access of the Airflow, d. H. the suction air flow, not obstructed.

Alternativ besteht auch die Möglichkeit, dass die Saugvorrichtung 4 unterhalb und die Klappe 12 oberhalb der Faserbündelungszone F angeordnet ist. Das durch das Gegengewicht 24 ausgeübte Moment ist auch in diesem Fall größer als die Masse der Klappe 12, so dass diese Klappe 12 nach oben abzuheben bestrebt ist, wobei der Saugzug sie dann nach unten ziehen kann. Alternatively, there is also the possibility that the suction device 4 below and the flap 12 is arranged above the fiber bundling zone F. That through that Counterweight 24 moment exerted in this case is also greater than the mass the flap 12, so that this flap 12 tends to lift up, wherein the suction can then pull them down.

Die Klappe kann quadratisch, rechteckig, kreisförmig, elliptisch oder in sonstiger Weise geformt sein, wobei in jedem Fall sichergestellt sein muss, dass diese Einrichtung zum Erfassen der Saugluftströmung funktionssicher arbeitet.The flap can be square, rectangular, circular, elliptical or otherwise Be shaped, in any case it must be ensured that this device works reliably to detect the suction air flow.

In der in Fig. 1 dargestellten Position wird die Klappe 12 in der ausgezogenen Lage gehalten. Tritt eine Störung der Saugluftströmung auf, beispielsweise reduziert sich diese oder fällt sie weg, so bewegt sich die Klappe 12 entgegen dem Uhrzeigersinn nach unten und kann an dem Anschlag 22 aufliegen, wodurch über den Signalstromkreis 18 die beispielsweise als Alarmeinrichtung 20 ausgebildete Einheit ein Signal abgibt. Ist der Fehler behoben, d. h. liegt die funktionssichere Saugzugströmung vor, schwenkt die Klappe 12 im Uhrzeigersinn, bis sie wieder die in Fig. 1 dargestellte ausgezogene Position einnimmt.In the position shown in Fig. 1, the flap 12 is in the extended Location held. If there is a disturbance in the suction air flow, for example reduced If this falls or falls away, the flap 12 moves against it Clockwise downwards and can rest on the stop 22, whereby over the signal circuit 18, which is designed, for example, as an alarm device 20 Unit emits a signal. Is the error corrected? H. lies the reliable Before the suction draft, the flap 12 swivels clockwise until it is again occupies the extended position shown in Fig. 1.

Die erfindungsgemäße Vorrichtung ist einfach gestaltet und trotzdem in der Lage, die Saugluftströmung funktionsrichtig zu kontrollieren.The device according to the invention is simple in design and is nevertheless able to Check the suction air flow in the correct way.
