Description

Die vorliegende Erfindung betrifft eine Offenend-Spinnmaschine mit einer Vielzahl nebeneinander angeordneter Arbeitsstellen mit Offenend-Spinnvorrichtungen, die jeweils eine Faserbandauflöseeinrichtung mit einer Schmutzaustrittsöffnung aufweisen. Eine sich in Maschinenlängsrichtung erstreckende Schmutzentsorgungseinrichtung ist unterhalb der Schmutzaustrittsöffnungen angeordnet.The present invention relates to an open-end spinning machine with a plurality of juxtaposed jobs with open-end spinning devices, each having a sliver disintegrating device with a dirt outlet opening. A dirt removal device extending in the machine longitudinal direction is arranged below the dirt outlet openings.

Bei einer Offenend-Spinnvorrichtung wird ein Faserband einer Faserbandauflöseeinrichtung zugeführt, bevor die Einzelfasern in den Spinnrotor gelangen. Die Faserbandauflöseeinrichtung ist nach unten hin offen. Die Öffnung dient als Schmutzaustrittsöffnung.In an open-end spinning device, a sliver is fed to a sliver breaker before the single fibers enter the spinning rotor. The sliver breaker is open at the bottom. The opening serves as a dirt outlet opening.

Aus der DE 198 27 610 B4 oder der DE 102 22 012 A1 ist bekannt, unterhalb der Schmutzaustrittsöffnungen eine sich in Maschinenlängsrichtung erstreckende Schmutzentsorgungseinrichtung anzuordnen. Die Schmutzentsorgungseinrichtung kann als in Maschinenlängsrichtung verlaufendes Förderband ausgebildet sein, welches die bei der Faserbandauflösung auftretenden Schmutzpartikel aufnimmt und abtransportiert. Die Schmutzpartikel fallen auf das Förderband und werden von diesem zu pneumatischen Schmutzabsaugeinrichtungen im Bereich der Maschinenendgestelle befördert.From the DE 198 27 610 B4 or the DE 102 22 012 A1 It is known to arrange below the dirt outlet openings extending in the machine longitudinal direction dirt disposal device. The dirt removal device can be designed as a conveyor belt running in the machine longitudinal direction, which picks up and removes the dirt particles occurring during the fiber sliver dissolution. The dirt particles fall on the conveyor belt and are transported by this to pneumatic Schmutzabsaugeinrichtungen in the field of Maschinenendgestelle.

Um zu verhindern, dass sich im Laufe der Zeit im Bereich der Schmutzaustrittsöffnungen durch Ansetzen von Verunreinigungen und Fasern ein Faserbart bilden kann, der in den Bereich einer Auflösewalze der Faserbandauflöseeinrichtung zurückgesaugt werden könnte und dann den Spinnbetrieb erheblich stören würde, ist auf dem Förderband ein bürstenartiges Reinigungselement angeordnet, dessen Borsten sich bis in den Bereich der Schmutzaustrittsöffnung erstrecken und damit ein Anwachsen des Faserbartes verhindern.In order to prevent the formation of impurities and fibers in the area of the dirt discharge openings over time, a fiber tuft could form, which could be sucked back into the area of an opening roller of the fiber sliver disassembling device and then significantly disturb the spinning operation, is a brush-like on the conveyor belt Cleaning element arranged, the bristles extend into the region of the dirt outlet opening and thus prevent growth of the tuft.

Anstelle des Förderbandes kann auch, wie in DE 102 22 012 A1 gezeigt, ein sich in Maschinenlängsrichtung bewegender Schlitten mit Schiebeflächen verwendet werden, der die Schmutzpartikel in einer Rinne zu den Maschinenendgestellen transportiert. Dieser Schlitten kann gleichzeitig die bürstenartigen Reinigungselemente aufnehmen.Instead of the conveyor belt can also, as in DE 102 22 012 A1 shown moving in the machine longitudinal direction slide with sliding surfaces are used, which transports the dirt particles in a groove to the Maschinenendgestellen. This carriage can simultaneously accommodate the brush-like cleaning elements.

Es wird vorgeschlagen, die Geschwindigkeit des Schlittens in Abhängigkeit von der Menge der Schmutzpartikel oder der Position des Schlittens anzupassen, um eine sichere Beseitigung der Schmutzpartikel von der Schmutzentsorgungseinrichtung zu gewährleisten.It is proposed to adjust the speed of the carriage depending on the amount of dirt particles or the position of the carriage to ensure a safe removal of the dirt particles from the waste disposal facility.

Es ist die Aufgabe der vorliegenden Erfindung, eine zuverlässige Schmutzentsorgung auch bei längeren Maschinen beziehungsweise größer werdender Anzahl von Arbeitsstellen zu gewährleisten.It is the object of the present invention to ensure a reliable removal of dirt even with longer machines or an increasing number of jobs.

Die Aufgabe wird erfindungsgemäß durch eine Offenend-Spinnmaschine mit einer Vielzahl nebeneinander angeordneter Arbeitsstellen mit Offenend-Spinnvorrichtungen gelöst, die jeweils eine Faserbandauflöseeinrichtung mit einer Schmutzaustrittsöffnung aufweisen. Bei der vorliegenden Erfindung ist eine sich in Maschinenlängsrichtung erstreckende Schmutzentsorgungseinrichtung unterhalb der Schmutzaustrittsöffnungen angeordnet und die Schmutzentsorgungseinrichtung ist dazu ausgebildet, Schmutzpartikel zu pneumatischen Schmutzabsaugeinrichtungen in den Bereich von Maschinenendgestellen zu befördern. Erfindungsgemäß ist zwischen den Arbeitsstellen mindestens eine Zwischeneinheit angeordnet, die eine weitere pneumatische Schmutzabsaugeinrichtung umfasst, die dazu ausgebildet ist, Schmutzpartikel von der Schmutzentsorgungseinrichtung abzusaugen.The object is achieved by an open-end spinning machine with a plurality of juxtaposed jobs with open-end spinning devices, each having a sliver opening device with a dirt outlet opening. In the present invention, a dirt removal device extending in the machine longitudinal direction is arranged below the dirt outlet openings and the dirt removal device is designed to convey dirt particles to pneumatic dirt suction devices in the region of machine end racks. According to the invention, at least one intermediate unit is arranged between the work stations, which comprises a further pneumatic dirt suction device, which is designed to suck up dirt particles from the dirt removal device.

Durch die erfindungsgemäße zwischen den Arbeitsstellen angeordnete Zwischeneinheit kann auf einfache Weise eine weitere Schmutzabsaugeinrichtung installiert werden. Durch die weitere Schmutzabsaugeinrichtung im Bereich der Arbeitsstellen, werden die Wege, die die Schmutzpartikel auf der Schmutzentsorgungseinrichtung transportiert werden müssen, verkürzt, und es werden größere Anhäufungen von Schmutzpartikeln vermieden. Die Schmutzpartikel können sicher und schnell entfernt werden.By means of the intermediate unit arranged between the work stations according to the invention, a further dirt suction device can be installed in a simple manner. As a result of the further dirt suction device in the area of the work stations, the paths which the dirt particles have to be transported to the dirt removal device are shortened, and larger accumulations of dirt particles are avoided. The dirt particles can be safely and quickly removed.

Vorzugsweise ist die Zwischeneinheit so ausgebildet, dass sie anstelle einer Arbeitsstelle montiert werden kann. Diese Ausbildung der Zwischeneinheit ist besonders vorteilhaft, da die bestehende Konstruktion einer Offenend-Spinnmaschine, beziehungsweise ihr Maschinenrahmen, nicht verändert werden muss. Außerdem können bereits ausgelieferte Maschinen leicht nachgerüstet werden.Preferably, the intermediate unit is designed so that it can be mounted instead of a job. This design of the intermediate unit is particularly advantageous since the existing construction of an open-end spinning machine, or its machine frame, does not have to be changed. In addition, already delivered machines can be easily retrofitted.

Vorzugsweise ist die Breite der Zwischeneinheit kleiner oder gleich der Breite einer Arbeitsstelle. Diese Anforderungen stellt eine Mindestanforderung für die Austauschbarkeit mit einer Arbeitsstelle dar. Für die Austauschbarkeit ist es jedoch am günstigsten, wenn die Breite der Zwischeneinheit und der Arbeitsstellen gleich ist.Preferably, the width of the intermediate unit is less than or equal to the width of a job. These requirements are a minimum requirement for interchangeability with a job. For interchangeability, however, it is best if the width of the intermediate unit and the jobs is the same.

Eine Zwischeneinheit kleinerer Breite als die Arbeitsstellen wird vorzugsweise in einer Zwischensektion untergebracht. Die Arbeitsstellen werden zu Gruppen zusammengefasst. Diese Gruppen werden als Sektion bezeichnet. Die Zwischeneinheit kann dann in einer eigenen Zwischensektion zwischen zwei Sektionen von Arbeitsstellen untergebracht werden. Der Vorteil dabei ist, dass die Zwischensektion nur so breit sein muss, wie die Zwischeneinheit. Man würde in diesem Fall die Zwischeneinheit so gestalten, dass sie eine möglichst geringe Breite aufweist, um keine Nutzlänge der Maschinen zu verschwenden. Eine Anordnung in einer Zwischensektion macht vor allem dann Sinn, wenn mehrere Zwischeneinheiten über die Länge der Maschine verteilt werden, da dann die geringere Breite der Zwischeneinheiten stärker ins Gewicht fällt.An intermediate unit of smaller width than the work stations is preferably accommodated in an intermediate section. The jobs are grouped together. These groups are called sections. The intermediate unit can then be accommodated in its own intermediate section between two sections of workplaces. The advantage of this is that the intermediate section only has to be as wide as the intermediate unit. In this case, one would design the intermediate unit so that it has the smallest possible width so as not to waste any useful length of the machines. An arrangement in an intermediate section makes sense especially when several intermediate units are distributed over the length of the machine, since then the smaller width of the intermediate units is more significant.

Die Austauschbarkeit der Zwischeneinheit und der Arbeitsstellen wird vorzugsweise dadurch unterstützt, dass die Zwischeneinheit und die Arbeitsstellen einander entsprechende Befestigungselemente zur Befestigung an einem Maschinenrahmen aufweisen. Solche Befestigungselemente können zum Beispiel Haken sein, die in eine korrespondierende Schiene am Maschinerahmen eingehängt werden.The interchangeability of the intermediate unit and the workstations is preferably supported by the fact that the intermediate unit and the workstations have corresponding fastening elements for attachment to a machine frame. Such fasteners may for example be hooks which are hooked into a corresponding rail on the machine frame.

Gemäß einer vorteilhaften Ausgestaltung der vorliegenden Erfindung ist die weitere pneumatische Schmutzabsaugeinrichtung an eine Unterdruckversorgung der Arbeitsstellen angeschlossen. Durch eine solche Ausgestaltung ist keine zusätzliche Unterdruckversorgung für die weitere pneumatische Schmutzabsaugeinrichtung erforderlich.According to an advantageous embodiment of the present invention, the further pneumatic Schmutzabsaugeinrichtung is connected to a vacuum supply of jobs. By such a configuration, no additional vacuum supply for the further pneumatic Schmutzabsaugeinrichtung is required.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawing.

Es zeigt:

It shows:
Fig. 1.
a front view of some juxtaposed open-end spinning devices of an open-end spinning machine according to the invention with a below their sliver disassembling means arranged dirt disposal device.

Die Fig. 1 zeigt eine Vorderansicht auf einige der in Reihe angeordneten Arbeitsstellen 20 einer Offenend-Spinnmaschine 1. Wie bekannt, sind bei modernen Offenend-Spinnmaschinen 1 pro Maschinenseite oft mehrere Hundert dieser Arbeitsstellen 20 nebeneinander angeordnet.The Fig. 1 shows a front view of some of the series-arranged workstations 20 of an open-end spinning machine 1. As is known, in modern open-end spinning machines 1 per side machine often several hundred of these jobs 20 are arranged side by side.

Die Arbeitsstellen 20 umfassen jeweils eine Offenend-Spinnvorrichtung 2.
Diese an sich bekannten und beispielsweise in der DE 195 24 837 A1 beschriebenen Offenend-Spinnvorrichtungen 2 besitzen ein besaugtes Rotorgehäuse, in dem mit hoher Drehzahl ein Spinnrotor umläuft. Das in Fig. 1 nicht dargestellte, nach vorne hin offene Rotorgehäuse ist während des Spinnbetriebes durch ein Deckelelement, einen sogenannten Schwenkdeckel 3 verschlossen. Der Schwenkdeckel 3 weist unter anderem auch eine Faserbandauflöseeinrichtung 4 auf.The work stations 20 each comprise an open-end spinning device 2.
These are known and, for example, in the DE 195 24 837 A1 Open-end spinning devices 2 described have an evacuated rotor housing in which rotates at high speed, a spinning rotor. This in Fig. 1 not shown, open towards the front rotor housing is closed during the spinning operation by a cover element, a so-called pivot cover 3. The swivel cover 3 also has, among other things, a sliver opening device 4.

Die Faserbandauflöseeinrichtung 4, die ein vorgelegtes Faserband 9 in spinnbare Einzelfasern zerlegt, besitzt dabei, wie üblich, eine in einem Auflösewalzengehäuse 5 rotierende Auflösewalze 6, eine Einzugswalze 7 sowie eine Speisemulde mit vorgeschaltetem Faserbandverdichter 8. Die Auflösewalzengehäuse 5 dieser Faserbandauflöseeinrichtungen 4 verfügen außerdem jeweils über eine Schmutzaustrittsöffnung 10 zum Abführen der bei der Faserbandauflösung anfallenden Schmutzbestandteile.The sliver opening device 4, which decomposes a sliver 9 presented in spinnable individual fibers, has, as usual, a rotating in an opening roller 5 opening roller 6, a feed roller 7 and a feed trough with upstream sliver compressor 8. The opening cylinder 5 of these sliver 4 also have each a dirt outlet opening 10 for discharging the resulting in the sliver dissolution dirt components.

Unterhalb der Schmutzaustrittsöffnungen 10 ist eine maschinenlange Schmutzentsorgungseinrichtung 11 angeordnet, die ein in einer Kanalkonstruktion 13 geführtes Endlos-Schmutzabtransportband 12 aufweist. Die Kanalkonstruktion 13 besitzt dabei, wie üblich, einen nach oben hin offenen Schmutzabtransportkanal 14 sowie einen darunterliegenden Rücklaufkanal 15. Das Endlos-Schmutzabtransportband 12 ist über einen (nicht dargestellten) E-Motor changierbar angetrieben.Below the dirt outlet openings 10, a machine-length dirt disposal device 11 is arranged, which has a guided in a channel construction 13 endless Schmutzabtransportband 12. The channel construction 13 has, as usual, an upwardly open Schmutzabtransportkanal 14 and an underlying return channel 15. The endless Schmutzabtransportband 12 is driven changeable via an electric motor (not shown).

Auf dem im Schmutzabtransportkanal 14 verlaufenden Abschnitt des Endlos-Schmutztransportbandes 12 ist ein Reinigungsschlitten 16 angeordnet, der während des Betriebes vom Schmutzabtransportband 12 über Reibschluss mitgenommen wird. Die Reinigungsschlitten verhindern die Ansammlung von Schmutzpartikeln an der Schmutzaustrittsöffnung 10. Die aus der Schmutzaustrittsöffnung austretenden und die von der Reinigungseinrichtung gelösten Schmutzpartikel fallen auf das Schmutzabtransportband 12 und werden von diesem in Richtung der Maschineenden abtransportiert.On the running in Schmutzabtransportkanal 14 section of the endless dirt conveyor belt 12, a cleaning slide 16 is arranged, which during operation is carried along by Schmutzabtransportband 12 via friction. The cleaning carriages prevent the accumulation of dirt particles on the dirt outlet opening 10. The dirt particles emerging from the dirt outlet opening and the particles of dirt dissolved by the cleaning device fall onto the dirt removal belt 12 and are transported away from it in the direction of the machine ends.

Die Offenend-Spinnmaschine 1 weist an den Maschinenenden nicht dargestellte Maschinenendgestelle auf, die in bekannter Weise pneumatische Schmutzabsaugeinrichtungen enthalten, die die auf dem Schmutzabtransportband 12 angelieferten Schmutzpartikel absaugen.The open-end spinning machine 1 has at the machine ends not shown Maschinenendgestelle that contain in a known manner pneumatic Schmutzabsaugeinrichtungen that suck the delivered on the Schmutzabtransportband 12 dirt particles.

Bei der in Fig. 1 dargestellten Offenend-Spinnmaschine 1 ist zwischen den Arbeitsstellen 20 eine Zwischeneinheit 17 angeordnet, die eine weitere pneumatische Schmutzabsaugeinrichtung 18 umfasst. Es können weitere Zwischeneinheiten 17 über die Maschinelänge verteilt angeordnet sein. Die Schmutzabsaugeinrichtung 18 ist auf das Schmutzabtransportband 12 gerichtet und saugt auf dem Schmutzabtransportband 12 vorbeilaufende Schmutzpartikel ab.At the in Fig. 1 Open-end spinning machine 1 shown an intermediate unit 17 is arranged between the work stations 20, which includes a further pneumatic dirt suction 18. There may be arranged more intermediate units 17 distributed over the machine length. The dirt suction device 18 is directed to the dirt removal belt 12 and sucks on the Schmutzabtransportband 12 passing dirt particles.

In dem dargestellten Ausführungsbeispiel ist die Zwischeneinheit 17 so ausgebildet, dass sie anstelle einer Arbeitsstelle 20 montiert werden kann. Die Zwischeneinheit 17 weist die gleiche Breite auf wie die Arbeitsstellen 20. Die Befestigung der Zwischeneinheit 17 an dem Maschinenrahmen erfolgt in gleicher Weise, wie die Befestigung der Arbeitsstellen. Die Schmutzabsaugeinrichtung 18 ist an die Unterdruckversorgung der Arbeitsstellen angeschlossen. Die Unterversorgung der Schmutzabsaugeinrichtung 18 kann dabei insbesondere über die Unterdruckversorgung einer nicht dargestellten Saugdüse erfolgen. Die schwenkbare Saugdüse dient an den Arbeitsstellen dazu, nach einer Fadenunterbrechung einen auf die Auflaufspule aufgelaufenen Faden zu erfassen und zum Wiederanspinnen zu der Offenend-Spinnvorrichtung 2 zu transportieren.In the illustrated embodiment, the intermediate unit 17 is designed so that it can be mounted instead of a workstation 20. The intermediate unit 17 has the same width as the workstations 20. The attachment of the intermediate unit 17 to the machine frame takes place in the same way as the fastening of the workstations. The dirt suction device 18 is connected to the vacuum supply of the jobs. The undersupply of the dirt suction device 18 can be effected in particular via the vacuum supply of a suction nozzle, not shown. The pivotable suction nozzle is used at the workstations to capture after a thread interruption accumulated on the package reel thread and to transport for re-spinning to the open-end spinning device 2.
