Description

Gegenstand der vorliegenden Erfindung ist ein Auflösewalzengehäuse einer Auflösevorrichtung einer Offenend-Rotorspinnvorrichtung mit einer Zuführöffnung für das Zuführen des Faserbands, mit einer Abfuhröffnung für das Abführen von Fasern aus dem Auflösewalzengehäuse, sowie mit einer Schmutzabscheideöffnung in der Umfangswand des Auflösewalzengehäuses.The present invention relates to an opening roller housing of an opening device of an open-end rotor spinning device with a feed opening for feeding in the sliver, with a discharge opening for removing fibers from the opening roller housing, and with a dirt separation opening in the peripheral wall of the opening roller housing.

Zur Vorbereitung des Verspinnens von faserförmigem Gut zu Garnen wird bei Offenend-Spinnvorrichtungen ein Faserband mittels einer Auflösewalzeneinrichtung zu Einzelfasern aufgelöst. Das Auflösen der Fasern geschieht durch eine Auflösewalze, die infolge bspw. einer gezahnten Garnitur an ihrem Umfang das ihr vorgelegte Faserband durch Auskämmen in Einzelfasern auflöst. Dieser Auflöseprozess geschieht in einem Auflösewalzengehäuse, in dem die Auflösewalze drehbar angeordnet und wo durch eine Zuführöffnung des Auflösewalzengehäuses das Faserband mit einer Speisevorrichtung der Auflösewalze zugeführt wird.To prepare for the spinning of fibrous material into yarns, in open-end spinning devices, a sliver is opened up into individual fibers by means of an opening roller device. The fibers are opened by an opening roller which, as a result of, for example, a toothed clothing on its circumference, opens the sliver presented to it into individual fibers by combing it out. This opening process takes place in an opening roller housing in which the opening roller is rotatably arranged and where the fiber sliver is fed to the opening roller with a feed device through a feed opening in the opening roller housing.

In Umfangsrichtung der sich drehenden Auflösewalze betrachtet ist nach der Zuführöffnung eine Schmutzabscheideöffnung vorhanden. Der Schmutz, bspw. bei Naturfasern wie Baumwolle oder bei Baumwolle/Chemiefasermischungen, Staub, Nissen, Schalenreste oder dergleichen, wird durch diese Öffnung herausgeschleudert und verlässt damit den dem Faserleitkanal zustrebenden Faserstrom. Ein solches Auflösewalzengehäuse ist beispielsweise aus der GB 2 164 671 A bekannt.Viewed in the circumferential direction of the rotating opening roller, there is a dirt separation opening after the feed opening. The dirt, for example in the case of natural fibers such as cotton or in the case of cotton/chemical fiber mixtures, dust, neps, remains of husks or the like, is thrown out through this opening and thus leaves the fiber flow heading for the fiber guide channel. Such an opening roller housing is, for example, from GB 2 164 671A known.

Weiterhin in Umfangsrichtung gesehen ist nach der Schmutzabscheideöffnung eine Abfuhröffnung angeordnet, durch welche die vereinzelten Fasern aus dem Auflösewalzengehäuse herausgeführt werden. Durch einen Faserleitkanal hindurch gelangen die Fasern dann in den Spinnrotor, wo sie versponnen werden.Furthermore, viewed in the circumferential direction, a discharge opening is arranged after the dirt separation opening, through which the separated fibers are guided out of the opening roller housing. The fibers then pass through a fiber guide channel into the spinning rotor, where they are spun.

Aus der DE 33 24 629 A1 ist es bekannt, die Mantelfläche des Innenraumes eines Auflösewalzengehäuses mit einer dünnwandigen Auskleidung abzudecken. Diese dient ausschließlich dem Verschleißschutz. Eine Anpassung an veränderte Spinnbedingungen ist nicht möglich. Dementsprechend weist die DE 32 07 575 A1 einen Einsatz zum Schutz des Auflösewalzengehäuses auf, der eine Topfform aufweist und aus dünnem Blech besteht.From the DE 33 24 629 A1 it is known to cover the outer surface of the interior of an opening roller housing with a thin-walled lining. This serves exclusively to protect against wear. An adaptation to changed spinning conditions is not possible. Accordingly, the DE 32 07 575 A1 an insert to protect the opening roller housing, which has a cup shape and is made of thin sheet metal.

Aus der DE 44 16 977 A1 ist ein Auflösewalzengehäuse bekannt, welches mit einem als Auskleidung ausgebildeten Einsatz versehen ist.From the DE 44 16 977 A1 an opening roller housing is known which is provided with an insert designed as a lining.

Aus der DE 102 24 589 A1 ist ein Auflösewalzengehäuse bekannt, bei dem die Umfangswand des Auflösewalzengehäuses zwischen der Schmutzabscheidung und der Abfuhröffnung für Fasern durch einen austauschbaren Einsatz gebildet wird. Dadurch soll die Schmutzabscheidung an verschiedene Fasern angepasst werden können. Dieses Auflösewalzengehäuse hat den Nachteil, dass zwar die Größe der Schmutzabscheidung variiert werden kann, jedoch ist der bekannte Einsatz nicht dazu geeignet, Auflösewalzengehäuse variabel auszubilden, so dass diese auf verschiedene Fasermaterialien und andere Spinnbedingungen angepasst werden können.From the DE 102 24 589 A1 an opening roller housing is known in which the peripheral wall of the opening roller housing between the dirt separator and the discharge opening for fibers is formed by an exchangeable insert. This should allow the dirt separation to be adapted to different fibers. This opening roller housing has the disadvantage that although the size of the dirt separation can be varied, the known use is not suitable for making opening roller housings variable, so that they can be adapted to different fiber materials and other spinning conditions.

Es ist bekannt, dass die Auflösewalzengehäuse der Auflösevorrichtungen im Wesentlichen aus einzelnen Segmenten bestehen, die auf einer Trägerplatte angeordnet sind. Die einzelnen, auf die Trägerplatte aufgesetzten Segmente bilden somit die Umfangswand des Auflösewalzengehäuses. In der EP 1 462 550 A1 ist vorgeschlagen worden, dass ein Einsatz sich bis in den Bereich der Schmutzabscheideöffnung erstreckt und teilweise die Umfangswand des Auflösewalzengehäuses im Bereich der Schmutzabscheideöffnung bildet. Nachteilig hierbei ist die aufwendige konstruktive Ausgestaltung des Einsatzes. Außerdem stört, dass die Außenkontur des Einsatzes mit der Innenfläche der Umfangswand des Auflösewalzengehäuses fluchtet, so dass der Ringspalt zwischen Auflösewalze und Einsatz in radialer Richtung nicht änderbar ist.It is known that the opening roller housings of the opening devices essentially consist of individual segments which are arranged on a carrier plate. The individual segments placed on the carrier plate thus form the peripheral wall of the opening roller housing. In the EP 1 462 550 A1 it has been proposed that an insert extends into the area of the dirt separation opening and partially forms the peripheral wall of the opening roller housing in the area of the dirt separation opening. The disadvantage here is the complex structural design of the insert. It is also annoying that the outer contour of the insert is aligned with the inner surface of the peripheral wall of the opening roller housing, so that the annular gap between the opening roller and the insert cannot be changed in the radial direction.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Einsatz für ein Auflösewalzengehäuse anzugeben, der konstruktiv einfach ist und leicht zu montieren sowie zu demontieren, insbesondere auszutauschen ist. Des Weiteren soll der Einsatz einfach und kostengünstig herstellbar sein. Außerdem soll der Austausch eine Einstellung auf verschiedene Spinnbedingungen ermöglichen.Proceeding from this, the present invention is based on the object of specifying an insert for an opening roller housing that is structurally simple and easy to assemble and disassemble, in particular to replace. Furthermore, the insert should be simple and inexpensive to produce. In addition, the exchange should allow adjustment to different spinning conditions.

Diese Aufgabe wird erfindungsgemäß durch ein Auflösewalzengehäuse mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen des erfindungsgemäßen Auflösewalzengehäuses sind Gegenstand der abhängigen Ansprüche.According to the invention, this object is achieved by an opening roller housing having the features of claim 1 . Advantageous developments and configurations of the opening roller housing according to the invention are the subject matter of the dependent claims.

Die in den abhängigen formulierten Ansprüchen einzeln aufgeführten Merkmale können in beliebiger, technologisch sinnvoller Weise miteinander kombiniert werden und weitere Ausgestaltungen der Erfindung definieren. Darüber hinaus werden die in den Ansprüchen angegebenen Merkmale in der Beschreibung näher präzisiert und erläutert, wobei weitere bevorzugte Ausführungsbeispiele der Erfindung dargestellt werden.The features listed individually in the dependent formulated claims can be combined with one another in any technologically meaningful way and define further refinements of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, with further preferred exemplary embodiments of the invention being presented.

Erfindungsgemäß wird ein Auflösewalzengehäuse für eine Auflösevorrichtung einer Offenend-Rotorspinnvorrichtung vorgeschlagen mit einer Zuführöffnung für das Zuführen eines Faserbands, mit einer Abfuhröffnung für das Abführen von Fasern aus dem Auflösewalzengehäuse sowie mit einer Schmutzabscheideöffnung in der Umfangswand des Auflösewalzengehäuses. Das Auflösewalzengehäuse umfasst einen austauschbaren Einsatz. Der Einsatz ist als hohlzylinderartiger Ring ausgebildet, der in der Zylinderwand zumindest einen Wandbereich mit einer Öffnung und einem muldenförmigen Fasereinlauf in die Abfuhröffnung und einen Wandbereich mit einer Öffnung zur Einstellung der Schmutzabscheideöffnung aufweist. Weiter stellt der Einsatz durch die Dicke seiner Zylinderwand den Ringspalt zwischen dem Auflösewalzengehäuse einer Auflösewalze ein.According to the invention, an opening roller housing for an opening device of an open-end rotor spinning device is proposed with a feed opening for feeding in a sliver, with a discharge opening for removing fibers from the opening roller housing and with a dirt separation opening in the peripheral wall of the opening roller housing. The opening roller housing includes a replaceable insert. The insert is designed as a hollow-cylindrical ring which has at least one wall area in the cylinder wall with an opening and a trough-shaped fiber inlet into the discharge opening and a wall area with an opening for adjusting the dirt separation opening. Furthermore, the insert adjusts the annular gap between the opening roller housing of an opening roller by the thickness of its cylinder wall.

Durch das erfindungsgemäße Auflösewalzengehäuse wird eine effiziente und einfache Möglichkeit aufgezeigt, eine Einstellung auf verschiedene Spinnbedingungen zu ermöglichen.The opening roller housing according to the invention shows an efficient and simple way of enabling adjustment to different spinning conditions.

Durch einfachen Austausch des Ringes ist die Länge und Form des Fasereinlaufs in Umfangsrichtung des Rings variierbar. Durch einen muldenförmigen Fasereinlauf kann der Einlaufbereich schon wesentlich vor dem Faserleitkanal erfolgen. Durch den Austausch des Ringes ist auch die Größe der Öffnung des Einsatzes zur Einstellung der Schmutzabscheideöffnung variierbar. Erfindungsgemäß ist der Ringspalt zwischen Auflösewalze und Einsatz durch Austausch des Ringes variierbar. Dazu können Einsätze mit unterschiedlichen Innendurchmessern des Innenhohlraums des Einsatzes verwendet werden.By simply replacing the ring, the length and shape of the fiber inlet can be varied in the circumferential direction of the ring. Due to a trough-shaped fiber inlet, the inlet area can take place significantly before the fiber guide channel. By exchanging the ring, the size of the opening of the insert for setting the dirt separation opening can also be varied. According to the invention, the annular gap between the opening roller and the insert can be varied by changing the ring. For this, inserts with different inner diameters of the inner cavity of the insert can be used.

Es kann für unterschiedliche Fasern und Anwendungen der entsprechend optimale Ring eingesetzt werden. Die Ringe erlauben einen unterschiedlichen Fasereinlaufbereich des Faserleitkanals. Ein weiterer Vorteil besteht darin, die Schmutzabscheideöffnung mehr oder weniger zu schließen bzw. zu öffnen. Auch kann der Ringspalt zwischen Auflösewalze und Ring im Bedarfsfall variiert werden.The optimal ring can be used for different fibers and applications. The rings allow a different fiber inlet area of the fiber duct. Another advantage is that the dirt separation opening can be more or less closed or opened. The annular gap between the opening roller and the ring can also be varied if necessary.

Der erfindungsgemäße Einsatz ist insbesondere dazu geeignet, durch einfaches Wechseln des Rings anwendungsspezifisch den passenden Faserleitkanal-Einlaufbereich zu wählen und/oder den Schmutzabscheidebereich so zu beeinflussen, dass der Anwender entscheiden kann, wie ausgereinigt sein Garn sein soll.The insert according to the invention is particularly suitable for selecting the appropriate fiber guide channel inlet area for an application by simply changing the ring and/or influencing the dirt separation area in such a way that the user can decide how cleared his yarn should be.

Der erfindungsgemäße Einsatz ist vorzugsweise einteilig ausgebildet. Hierdurch ist eine einfache Herstellung und Montage ermöglicht.The insert according to the invention is preferably designed in one piece. This enables simple manufacture and assembly.

Nach einer vorteilhaften Ausführung bildet der Einsatz die Umgrenzung der Zuführöffnung und/oder der Schmutzabscheideöffnung an wenigstens drei Seiten.According to an advantageous embodiment, the insert forms the delimitation of the feed opening and/or the dirt separation opening on at least three sides.

Nach einer weiteren vorteilhaften Ausgestaltung bildet der Einsatz die Umgrenzung der Abfuhröffnung.According to a further advantageous embodiment, the insert forms the delimitation of the discharge opening.

Entsprechend einer noch weiteren Ausbildung der Erfindung ist der Einsatz koaxial zur Auflösewalze angeordnet. Bevorzugt ist der Einsatz koaxial zur Umfangswand angeordnet.According to yet another embodiment of the invention, the insert is arranged coaxially to the opening roller. The insert is preferably arranged coaxially with the peripheral wall.

Bevorzugt weist der Einsatz eine umlaufende Stufe auf, die mit der Abdeckung eine Labyrinthdichtung bildet.The insert preferably has a circumferential step which forms a labyrinth seal with the cover.

Der Einsatz schützt das Gehäuse vor Verschleiß. Vorzugsweise ist der Einsatz verschleißgeschützt, um eine lange Lebensdauer zu gewährleisten. Der Einsatz kann bei Verschleiß aber auch leicht und kostengünstig ausgetauscht werden.The insert protects the housing from wear. The insert is preferably protected against wear in order to ensure a long service life. However, the insert can also be easily and inexpensively replaced if it is worn out.

Weitere Vorteile und Einzelheiten des erfindungsgemäßen Auflösewalzengehäuses werden anhand eines bevorzugten Ausführungsbeispiels erläutert, ohne dass der Gegenstand der Erfindung auf dieses konkrete Ausführungsbeispiel beschränkt wird. Es zeigen:

In Fig. 1 ist schematisch eine Offenend-Rotorspinnvorrichtung 1 dargestellt. Derartige Offenend-Rotorspinnvorrichtungen 1 verfügen, wie bekannt, jeweils über ein Rotorgehäuse 2, in dem die Spinntasse eines Spinnrotors 3 mit hoher Drehzahl umläuft.In 1 an open-end rotor spinning device 1 is shown schematically. As is known, such open-end rotor spinning devices 1 each have a rotor housing 2 in which the spinning cup of a spinning rotor 3 rotates at high speed.

Der Spinnrotor 3 ist dabei bspw. mit einem Rotorschaft 4 in den Lagerzwickeln einer sogenannten Stützscheibenlagerung 5 abgestützt und wird durch einen maschinenlangen Tangentialriemen 6, der durch eine Andrückrolle 7 beaufschlagt wird, reibschlüssig angetrieben.The spinning rotor 3 is, for example Tangential belt 6, which is acted upon by a pressure roller 7, driven by friction.

Die axiale Fixierung des Rotorschafts 4 erfolgt bspw. durch ein permanentmagnetisches Axiallager 18. Das nach vorn hin an sich offene Rotorgehäuse 2 ist während des Spinnbetriebs durch ein schwenkbar gelagertes Deckelelement 8 verschlossen, in das eine Kanalplatte eingelassen ist, die mit einer umlaufenden Mittendichtung 9 am Rotorgehäuse 2 anliegt.The rotor shaft 4 is axially fixed, for example, by a permanent magnetic axial bearing 18. The rotor housing 2, which is open towards the front, is closed during spinning by a pivotably mounted cover element 8, into which a channel plate is embedded, which is equipped with a circumferential center seal 9 on the Rotor housing 2 is present.

Das Rotorgehäuse 2 ist außerdem ist über eine entsprechende Unterdruckleitung 10 an eine Unterdruckquelle 11 angeschlossen, die den im Rotorgehäuse 2 notwendigen Spinnunterdruck erzeugt.The rotor housing 2 is also connected via a corresponding vacuum line 10 to a vacuum source 11 which generates the vacuum required for spinning in the rotor housing 2 .

In einer Aufnahme der (nicht näher dargestellten) Kanalplatte ist auswechselbar ein Kanalplattenadapter 12 angeordnet, der den Mündungsbereich eines Faserleitkanals 14 sowie eine Fadenabzugsdüse 13 aufweist, an die sich ein Fadenabzugsröllchen 15 anschließt.In a receptacle of the channel plate (not shown in more detail), a channel plate adapter 12 is exchangeably arranged, which has the mouth area of a fiber guide channel 14 and a yarn withdrawal nozzle 13 to which a yarn withdrawal roller 15 is connected.

Des Weiteren ist in das Deckelelement 8, das um eine Schwenkachse 16 begrenzt drehbar gelagert ist, eine Auflösevorrichtung 26 integriert.Furthermore, a dissolving device 26 is integrated into the cover element 8 , which is mounted so as to be rotatable to a limited extent about a pivot axis 16 .

Das heißt, das Deckelelement 8 weist ein Auflösewalzengehäuse 17 sowie rückseitige Lagerkonsolen 19, 20 zur Lagerung einer Auflösewalze 21 bzw. einer Speisewalze 22 auf. Mit 30 ist eine Abdeckung des Auflösewalzengehäuses 17 bezeichnet. Die Auflösewalze 21 wird dabei über einen umlaufenden, maschinenlangen Tangentialriemen 24, der einen Wirtel 23 der Auflösewalze 21 beaufschlagt, angetrieben, während der Antrieb der Speisewalze 22 vorzugsweise über eine maschinenlange Antriebswelle 25 bzw. ein (nicht dargestelltes) Schneckenradgetriebe erfolgt.This means that the cover element 8 has an opening roller housing 17 and rear bearing brackets 19, 20 for mounting an opening roller 21 and a feed roller 22, respectively. A cover of the opening roller housing 17 is denoted by 30 . The opening roller 21 is driven by a rotating, machine-long tangential belt 24, which acts on a whorl 23 of the opening roller 21, while the feed roller 22 is preferably driven by a machine-long drive shaft 25 or a worm gear (not shown).

In der Fig. 2 ist eine bevorzugte Ausgestaltung des erfindungsgemäßen Auflösewalzengehäuses 17 dargestellt. Das Faserband, die Auflösewalze 21 (siehe Fig. 1) sowie die vereinzelten Fasern sind zur Verdeutlichung der Erfindung weggelassen worden. Das Auflösewalzengehäuse 17 und die Auflösevorrichtung 26 ist geschnitten dargestellt und weist eine Zuführöffnung 27 für das aufzulösende Faserband sowie eine Schmutzabscheideöffnung 28 und eine Abfuhröffnung 29 zur Ableitung der ausgekämmten und vereinzelten Fasern durch den an das Auflösewalzengehäuse 17 anschließenden Faserleitkanal 14 zu der Spinnstelle (siehe Fig. 1). Die Schmutzabscheideöffnung 28 ist durch die Gehäuseseitenwand und durch die Wände 31.1 und 31.2 begrenzt, die ein Teil des Auflösewalzengehäuses 17 sind.In the 2 a preferred embodiment of the opening roller housing 17 according to the invention is shown. The sliver, the opening roller 21 (see 1 ) and the isolated fibers have been omitted to clarify the invention. The opening roller housing 17 and the opening device 26 are shown in section and have a feed opening 27 for the fiber sliver to be opened, as well as a dirt separation opening 28 and a discharge opening 29 for discharging the combed and separated fibers through the fiber guide channel 14 adjoining the opening roller housing 17 to the spinning station (see Fig 1 ). The dirt separation opening 28 is delimited by the housing side wall and by the walls 31.1 and 31.2, which are part of the opening roller housing 17.

Die Schmutzabscheideöffnung 28 führt über einen Schmutzabfuhrkanal 32 zu einem hier nicht dargestellten Sammel- oder Abtransportsystem für die ausgeschiedenen Schmutzteilchen.The dirt separation opening 28 leads via a dirt removal channel 32 to a collection or removal system for the separated dirt particles, not shown here.

Eine Speisewalze 22, die sich in Pfeilrichtung A dreht, zieht ein Faserband durch eine Verdichter 33 über eine bewegliche Speisemulde 34 in die Zuführöffnung 27 des Auflösewalzengehäuses 17 ein. Die Speisemulde 34 ist um einen Zapfen 35 an der Gehäusewandung drehbar gelagert. Die Speisemulde 34 wird von einer Feder 36 abgestützt und gegen die Speisewalze 22 gedrückt. Ändert sich der Zustand des Faserbands, bspw. seine Stärke, weicht die Speisemulde 34 nach unten aus.A feed roller 22, which rotates in the direction of arrow A, pulls a sliver through a compressor 33 via a movable feed trough 34 into the feed opening 27 of the opening roller housing 17. The feed trough 34 is rotatably mounted about a pin 35 on the housing wall. The feed trough 34 is supported by a spring 36 and pressed against the feed roller 22 . If the condition of the sliver changes, for example its thickness, the feed trough 34 moves downwards.

In dem Auflösewalzengehäuse 17 dreht sich eine Auflösewalze 21 in Teilrichtung B um ihre Achse, die in dem Auflösewalzengehäuse 17 gelagert ist. Die Auflösewalze 21 trägt auf ihrem Umfang eine (nicht dargestellte) Auflösegarnitur, die im vorliegenden Fall sägezahnartig ausgebildet ist. Diese Auflösegarnitur kämmt einzelne Fasern aus dem zugeführten Faserband. Aufgrund der in dem Auflösewalzengehäuse 17 herrschenden Luftströmung werden die einzelnen Fasern mit dem Luftstrom mitgenommen und durch den Faserleitkanal 14 dem Spinnaggregat zugeführt. Der aus dem Strom der vereinzelten Fasern ausgeschiedene Schmutz weist in der Regel eine größere Masse auf als die Fasern und wird deshalb im Wesentlichen tangential aus der Schmutzabscheideöffnung 28 herausgeschleudert. In der Kammer 37 des Auflösewalzengehäuses 17 ist eine Öffnung 38 zur Durchführung der Welle der Auflösewalze 21 zu sehen.In the opening roller housing 17 , an opening roller 21 rotates in partial direction B about its axis, which is mounted in the opening roller housing 17 . The opening roller 21 carries an opening fitting (not shown) on its circumference, which in the present case has a sawtooth-like design. This opening assembly combs individual fibers from the supplied sliver. Due to the air flow prevailing in the opening roller housing 17, the individual fibers are carried along with the air flow and fed to the spinning unit through the fiber guide channel 14. The dirt separated from the stream of separated fibers generally has a greater mass than the fibers and is therefore thrown out of the dirt separation opening 28 essentially tangentially. In the chamber 37 of the opening roller housing 17, an opening 38 for the passage of the shaft of the opening roller 21 can be seen.

In der Umfangswand 39 des Auflösewalzengehäuses 17 sind somit die Zuführöffnung 27 für das Zuführen des Faserbands, die Abfuhröffnung 29 für das Abführen von Fasern aus dem Auflösewalzengehäuse 17 sowie die Schmutzabscheideöffnung 28 vorhanden.In the peripheral wall 39 of the opening roller housing 17, the feed opening 27 for feeding in the sliver, the discharge opening 29 for removing fibers from the opening roller housing 17 and the dirt separation opening 28 are present.

In der Kammer 37 des Auflösewalzengehäuses 17 ist der erfindungsgemäße Einsatz 40 angeordnet. Der Einsatz 40 ist koaxial zur Auflösewalze 21 (siehe Fig. 1) und zur Umfangswand 39 angeordnet. Der Einsatz 40 ist mit Hilfe von (nicht dargestellten) Befestigungsmitteln, z. B. Schrauben oder Passstiften, an der Seitenwand des Auflösewalzengehäuses 17 austauschbar befestigt.The insert 40 according to the invention is arranged in the chamber 37 of the opening roller housing 17 . The insert 40 is coaxial to the opening roller 21 (see 1 ) and to the peripheral wall 39 arranged. The insert 40 is secured by means of fasteners (not shown), e.g. B. screws or dowel pins, attached to the side wall of the opening roller housing 17 interchangeably.

Der Einsatz 40 ist nach Fig. 2 und 3 als hohlzylinderartiger Ring 41 mit einer Zylinderwand 42 und einem Innenhohlraum 43 ausgebildet. Der Einsatz 40 weist in der Zylinderwand 42 einen Wandbereich mit einer durchgehenden ersten Öffnung 44 und einem Fasereinlauf 45 auf. Die Länge des Fasereinlaufs 45 erstreckt sich über etwa ein Drittel des Umfangs des ringförmigen Einsatzes 40. Der Fasereinlauf 45 ist in axialer Richtung durch Bereiche der Zylinderwand 42 und in Umfangsrichtung an einem Ende durch die Abfuhröffnung 29 begrenzt. Das andere Ende des Fasereinlaufs 45 geht in Umfangsrichtung gleitend in die Zylinderwand 42 über, wodurch ein stufenloser Faserlauf verwirklicht ist. Der Fasereinlauf 45 ist muldenförmig mit einer Grundfläche und zwei aufgebogenen Seitenwänden ausgestaltet.Bet 40 is after 2 and 3 designed as a hollow-cylindrical ring 41 with a cylinder wall 42 and an inner cavity 43 . The insert 40 has in the cylinder wall 42 a Wall area with a continuous first opening 44 and a fiber inlet 45 on. The length of the fiber inlet 45 extends over approximately one third of the circumference of the annular insert 40. The fiber inlet 45 is limited in the axial direction by areas of the cylinder wall 42 and in the circumferential direction at one end by the discharge opening 29. The other end of the fiber inlet 45 transitions into the cylinder wall 42 in a sliding manner in the circumferential direction, as a result of which a stepless fiber run is realized. The fiber inlet 45 is designed in the form of a trough with a base area and two side walls that are bent up.

Weiterhin weist der Einsatz 40 in der Zylinderwand 42 einen Wandbereich mit einer durchgehenden zweiten Öffnung 46 auf. Die zweite Öffnung 46 liegt der Zuführöffnung 27 und der Schmutzabscheideöffnung 28 gegenüber und erlaubt sowohl den Durchtritt von aufgelösten Fasern zur Auflösewalze 21 als auch den Durchtritt von abgeschiedenem Schmutz aus dem Ringspalt in die Schmutzabscheideöffnung 28. Die Zylinderwand 42 bildet die Umgrenzung der zweiten Öffnung 46 an drei Seiten. An der vierten Seite ist die zweite Öffnung 46 offen.Furthermore, the insert 40 in the cylinder wall 42 has a wall area with a second opening 46 running through it. The second opening 46 is opposite the feed opening 27 and the dirt separation opening 28 and allows both the passage of dissolved fibers to the opening roller 21 and the passage of separated dirt from the annular gap into the dirt separation opening 28. The cylinder wall 42 forms the boundary of the second opening 46 three pages. On the fourth side, the second opening 46 is open.

Der Ring 41 weist eine umlaufende Stufe 47 auf, die mit der Abdeckung 30 des Auflösewalzengehäuses 17 eine Labyrinthdichtung bildet.
