Description

Die Erfindung betrifft eine Offenend-Rotorspinnvorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to an open-end rotor spinning device according to the preamble of claim 1.

Wie in der Textilmaschinenindustrie bekannt und in zahlreichen Patentschriften beschrieben, verfügen Offenend-Rotorspinn-vorrichtungen über einen Spinnrotor, der während des Spinnprozesses mit hoher Drehzahl in einem unterdruckbeaufschlagten Rotorgehäuse umläuft.
Das nach vorne hin an sich offene Rotorgehäuse ist während des Spinnprozesses durch ein Deckelelement luftdicht verschlossen, in das ein auswechselbarer Kanalplattenadapter eingelassen ist. Das Deckelelement verfügt in der Regel außerdem über ein Auflösewalzengehäuse sowie Lagerkonsolen für eine Auflösewalze und einen Faserbandzuführzylinder, und ist über eine Schwenkachse, die orthogonal zu den Rotationsachsen von Auflösewalze und Faserbandzuführzylinder angeordnet ist, begrenzt beweglich mit einem zugehörigen Spinnboxgehäuse verbunden, das beispielsweise die Lagerung und den Antrieb für den Spinnrotor aufweist. In solchen Offenend-Rotorspinnvorrichtungen werden die von der Auflösewalze aus einem Vorlage-Faserband ausgekämmten Einzelfasern über einen sogenannten Faserleitkanal zum umlaufenden Spinnrotor befördert und von diesem zu einem fortlaufend abziehbaren Faden versponnen.As known in the textile machinery industry and described in numerous patents, open-end rotor spinning devices have a spinning rotor that rotates during the high-speed spinning process in a vacuum-pressurized rotor housing.
The forwardly open itself to the rotor housing is hermetically sealed during the spinning process by a cover element, in which a replaceable channel plate adapter is embedded. The lid member usually also has a Auflösewalzengehäuse and bearing brackets for an opening roller and a Faserbandzuführzylinder, and is connected via a pivot axis which is arranged orthogonal to the axes of rotation of the opening roller and Faserbandzuführzylinder limited movably connected to an associated spin box housing, for example, the storage and having the drive for the spinning rotor. In such open-end rotor spinning devices, the individual fibers which are combed out of the opening roller from a master fiber sliver are conveyed via a so-called fiber guide channel to the revolving spinning rotor and are spun by this into a continuously removable thread.

Die Faserleitkanäle dieser bekannten Offenend-Rotorspinnvorrichtungen sind meistens zweiteilig ausgebildet. Das heißt, in der Regel ist in einer Lagerbohrung des Auflösewalzengehäuses ein Faserleitkanaleinsatz angeordnet, der den eingangsseitigen Kanalabschnitt eines Faserleitkanals aufweist, während der ausgangsseitige Kanalabschnitt des Faserleitkanals innerhalb eines auswechselbaren Kanalplattenadapters angeordnet ist, der, wie vorstehend erwähnt, in einer entsprechenden Aufnahme im Deckelelement festlegbar ist.The Faserleitkanäle these known open-end rotor spinning devices are usually formed in two parts. That is, usually in a bearing bore of the opening roller housing a Faserleitkanaleinsatz is arranged, which has the input-side channel portion of a Faserleitkanals, while the output-side channel portion of the Faserleitkanals is disposed within an interchangeable Kanalplattenadapters, as mentioned above, in a corresponding receptacle in the lid member can be fixed is.

Während des Betriebes reicht der in der Aufnahme des Deckelelementes lagegenau fixierte, bei Bedarf auswechselbare Kanalplattenadapter, der neben dem ausgangsseitigen Kanalabschnitt des Faserleitkanals auch eine Durchgangsbohrung zum Festlegen einer Fadenabzugsdüse aufweist, mit einem turmartigen Vorsatz in den umlaufenden Spinnrotor.During operation, in the recording of the lid member positionally accurate fixed, replaceable if necessary channel plate adapter, which has in addition to the output side channel portion of the fiber guide also has a through hole for fixing a thread take-off, with a tower-like intent in the rotating spinning rotor.

Im Zusammenhang mit Offenend-Rotorspinnvorrichtungen ist es außerdem seit langem bekannt, dass, um Offenend-Garne von guter Qualität herstellen zu können, gewisse Randbedingungen, beispielsweise bezüglich der gegenseitigen Anordnung und Dimensionierung der Spinnelemente, erfüllt sein müssen.
Die Gestaltung und Anordnung des Faserleitkanals, insbesondere der Abstand der Faserleitkanalmündung zur Faserrutschfläche im Spinnrotor sowie die Ausbildung und der Verlauf des lichten Faserleitkanalquerschnitts, haben einen nicht unerheblichen Einfluss auf die erzielbare Garnqualität.
Im Interesse optimaler Spinnergebnisse ist es daher vorteilhaft, jedem Spinnrotor, insbesondere entsprechend seinem Durchmesser, einen geeigneten Kanalplattenadapter zuzuordnen.
Das bedeutet, in der Praxis findet, wenn zum Beispiel im Zuge eines Garnpartiewechsels ein Austausch der Spinnrotoren vorgenommen wird, oft auch ein Wechsel der Kanalplattenadapter statt.Furthermore, in the context of open-end rotor spinning devices, it has long been known that in order to produce good quality open-end yarns, certain constraints, such as the disposition and dimensioning of the spinning elements, must be met.
The design and arrangement of the Faserleitkanals, in particular the distance of the Faserleitkanalmündung to the fiber sliding surface in the spinning rotor and the formation and the course of the clear Faserleitkanalquerschnitts have a significant influence on the achievable yarn quality.
In the interest of optimal spinning results, it is therefore advantageous to assign each spinning rotor, in particular according to its diameter, a suitable channel plate adapter.
This means that, in practice, if, for example, a replacement of the spinning rotors is carried out in the course of a yarn lot change, a change of the channel plate adapter often takes place.

Durch die DE 198 36 066 A1 , die DE 39 23 060 A1 und DE 103 48 710 A1 sind beispielsweise Offenend-Spinnvorrichtungen bekannt, die jeweils mit einem zweiteiligen Faserleitkanal ausgestattet sind.
Ein in einem Faserleitkanaleinsatz, der in einer Lagerbohrung des Auflösewalzengehäuses festgelegt ist, angeordneter eingangsseitiger Kanalabschnitt und ein im Deckelelement oder in einem Kanalplattenadapter angeordneter ausgangsseitiger Kanalabschnitt eines Faserleitkanals sind dabei so angeordnet, dass die Mittellängslinien der Kanalabschnitte zueinander unter einem vorteilhaften Winkel geneigt angeordnet sind.By the DE 198 36 066 A1 , the DE 39 23 060 A1 and DE 103 48 710 A1 For example, open-end spinning devices are known, which are each equipped with a two-part Faserleitkanal.
An input-side channel section arranged in a fiber guide channel insert which is fixed in a bearing bore of the opening roller housing and an output-side channel section of a fiber guide channel arranged in the cover element or in a channel plate adapter are arranged such that the central longitudinal lines of the channel sections are inclined relative to one another at an advantageous angle.

Eine solche geneigte Anordnung der Kanalabschnitte eines Faserleitkanals hat sich bezüglich des pneumatischen Fasertransportes als vorteilhaft herausgestellt, insbesondere wenn der Winkel zwischen den Mittellängslinien der Kanalabschnitte jeweils exakt auf die vorliegenden Garn- und/oder Spinnparameter abgestimmt ist.Such an inclined arrangement of the channel sections of a fiber guide channel has been found to be advantageous with respect to the pneumatic fiber transport, in particular if the angle between the central longitudinal lines of the channel sections is exactly matched to the present yarn and / or spinning parameters.

Eine Offenend-Spinnvorrichtung mit einem Faserleitkanal, der geneigt angeordnete Kanalabschnitte aufweist, ist auch Gegenstand der EP 0 311 988 A1 .
In dieser Literaturstelle ist eine Offenend-Spinnvorrichtung beschrieben, bei der der Eingangsbereich eines Faserleitkanals in ein Auflösewalzengehäuse eingearbeitet und der zugehörige Ausgangsbereich des Faserleitkanals Bestandteil einer Kanalplatte ist. Der Neigungswinkel zwischen dem fest in das Auflösewaizengehäuse integrierten Eingangsbereich eines Faserleitkanals und dem in der Kanalplatte angeordneten Ausgangsbereich eines Faserleitkanals ist dabei dadurch etwas entschärft, dass der in der Kanalplatte angeordnete Ausgangsbereich des Faserleitkanals mit einem zusätzlichen Neigungswinkel versehen ist.An open-end spinning device with a Faserleitkanal having inclined channel sections is also the subject of EP 0 311 988 A1 ,
In this reference, an open-end spinning device is described in which the input region of a fiber guide channel is incorporated into an opening roller housing and the associated output region of the fiber guide channel is part of a channel plate. The angle of inclination between the input region of a fiber guide channel which is permanently integrated in the dissolving wafer housing and the exit region of a fiber guide channel arranged in the channel plate is thereby somewhat relieved that the output region of the fiber guide channel arranged in the channel plate is provided with an additional inclination angle.

Da bei Kanalplattenadaptern, abhängig von der Größe des Kanalplattenadapters, der Verlauf des ausgangsseitigen Kanalabschnittes des Faserleitkanals oft durch die vorliegenden geometrischen Verhältnisse vorgegeben ist, besteht bei bestimmten Kanalplattenadaptergrößen die Gefahr, dass sich zwischen dem in einem Faserleitkanaleinsatz angeordneten eingangsseitigen Kanalabschnitt und dem in den Kanalplattenadapter integrierten ausgangsseitigen Kanalabschnitt ein Neigungswinkel einstellt, der spinntechnologisch nachteilig ist.Since channel plate adapters, depending on the size of the channel plate adapter, the course of the output-side channel portion of the Faserleitkanals is often dictated by the present geometric conditions, there is a risk for certain Kanalplattenadaptergrößen between the arranged in a Faserleitkanaleinsatz input side channel portion and integrated into the channel plate adapter Output side channel section adjusts an angle of inclination, which is disadvantageous spinning technology.

Es ist daher in der DE 10 2004 017 700 A1 bereits vorgeschlagen worden, den innerhalb des Kanalplattenadapters angeordneten, festliegenden, ausgangsseitigen Kanalabschnitt über eine Gelenkkugelverbindung an den eingangsseitigen Kanalabschnitt anzuschließen, der in einem Faserleitkanaleinsatz verläuft, der, wie üblich, in einer Lagerbohrung eines Auflösewalzengehäuses angeordnet ist.
Das Auflösewalzengehäuse ist dabei seinerseits begrenzt beweglich gelagert und kann zum Einstellen eines geeigneten Neigungswinkels zwischen den Kanalabschnitten definiert verstellt werden.It is therefore in the DE 10 2004 017 700 A1 has already been proposed to connect the fixed, output-side channel section, which is arranged within the channel plate adapter, via a joint ball connection to the input-side channel section, which runs in a fiber guide channel insert, which, as usual, is arranged in a bearing bore of an opening roller housing.
The opening roller housing is in turn limited movably mounted and can be adjusted to set a suitable angle of inclination between the channel sections defined.

Durch eine solche Konstruktion kann zwar weitestgehend vermieden werden, dass zwischen den Kanalabschnitten eines Faserleitkanals ungünstige Neigungswinkel auftreten, die Konstruktion ist allerdings recht aufwendig und relativ kostenintensiv.Although such a construction can be largely avoided that occur between the channel sections of a fiber guide unfavorable inclination angle, the construction is quite complex and relatively expensive.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Offenend-Rotorspinnvorrichtung der vorstehend beschriebenen Gattung zu schaffen, mit einem Faserleitkanal, dessen Ausbildung auf einfache Weise eine Optimierung der Faseraufspeisung auf die Faserrutschfläche eines Spinnrotors ermöglicht.Based on the aforementioned prior art, the present invention seeks to provide an open-end rotor spinning device of the type described above, with a Faserleitkanal, the formation of which allows a simple way to optimize the fiber feed to the fiber sliding surface of a spinning rotor.

Diese Aufgabe wird erfindungsgemäß durch eine Offenend-Spinnvorrichtung gelöst, die die im kennzeichnenden Teil des Anspruches 1 beschriebenen Merkmale aufweist.This object is achieved by an open-end spinning device having the features described in the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Eine Offenend-Rotorspinnvorrichtung mit einem Faserleitkanaleinsatz, der in einer Lagerbohrung eines Auflösewalzengehäuses festlegbar ist und bei dem das zweite Kanalabschnittsteil bezüglich einer zur Außenwandung des Faserleitkanaleinsatzes parallel angeordneten Bezugslinie unter einem Neigungswinkel verläuft, wobei der Neigungswinkel auf den jeweils eingesetzten Kanalplattenadapter abgestimmt ist, hat insbesondere den Vorteil, dass auch nach einem Austausch des Spinnrotors sowie des Kanalplattenadapters, beispielsweise infolge eines Wechsels der Garnpartie, durch die Verwendung eines passenden Faserleitkanaleinsatzes auf einfache und kostengünstige Weise sichergestellt werden kann, dass zwischen den Kanalabschnitten ein geeigneter Neigungswinkel gegeben ist und damit im Bereich des Faserleitkanals optimale Strömungsverhältnisse gegeben sind, wobei gleichzeitig eine optimale Faseraufspeisung auf die Faserrutschfläche des Spinnrotors gewährleistet ist.
Das heißt, nach einem durch das Wechseln des Spinnrotors notwendig gewordenen Austausch des Kanalplattenadapters kann durch den Einbau eines entsprechenden Faserleitkanaleinsatzes problemlos und kostengünstig sichergestellt werden, dass zwischen den Mittellängslinien der Kanalabschnitte des Faserleitkanals stets ein optimaler Neigungswinkel eingestellt ist.An open-end rotor spinning device with a Faserleitkanaleinsatz, which is fixed in a bearing bore of an opening roller housing and in which the second channel portion part extends with respect to a to the outer wall of the Faserleitkanaleinsatzes parallel reference line at an angle of inclination, the angle of inclination is tuned to the particular channel plate adapter used, in particular Advantage that even after replacement of the spinning rotor and the channel plate adapter, for example due to a change of yarn, by using a suitable Faserleitkanaleinsatzes can be ensured in a simple and inexpensive manner that between the channel sections a suitable inclination angle is given and thus in the fiber guide channel optimal flow conditions are given, at the same time ensuring optimum fiber feed to the fiber slipper surface of the spinning rotor.
That is, after having become necessary by replacing the spinning rotor replacement of the channel plate adapter can be easily and inexpensively ensured by the installation of a corresponding Faserleitkanaleinsatzes that between the central longitudinal lines of the channel sections of Faserleitkanals is always set an optimal angle of inclination.

Der Faserleitkanaleinsatz ist als zweiteiliges Bauteil ausgebildet.
Das in einer Lagerbohrung des Auflösewalzengehäuses festlegbare erste Bauteil weist den ersten Kanalabschnittsteil auf und das leicht austauschbare an diesem ersten Bauteil festlegbare zweite Bauteil ist mit dem zweiten Kanalabschnittsteil ausgestattet, der gegenüber dem ersten Kanalabschnittsteil des ersten Bauteils geneigt angeordnet ist.
Die Neigung des Kanalabschnittsteils des zweiten Bauteils ist dabei jeweils exakt auf einen bestimmten Kanalplattenadapter abgestimmt.
Das bedeutet, bei einem Spinnmittelwechsel mit Kanalplattenadaptertausch kann durch einen entsprechenden Wechsel des zweiten Bauteils des Faserleitkanaleinsatzes auf einfache Weise der Faserleitkanal der Offenend-Spinnvorrichtung auf die neuen Gegebenheiten angepasst werden.The Faserleitkanaleinsatz is designed as a two-part component.
The fixable in a bearing bore of the opening roller housing first component has the first channel portion portion and the easily replaceable fixable to this first component second component is equipped with the second channel portion portion which is inclined relative to the first channel portion portion of the first component.
The inclination of the channel section part of the second component is in each case matched exactly to a specific channel plate adapter.
This means that in a spin agent change with channel plate adapter replacement can be adapted to the new circumstances by a corresponding change of the second component of the Faserleitkanaleinsatzes easily the Faserleitkanal the open-end spinning device.

Wie in den Ansprüchen 2 und 3 beschrieben, ist das zweite Bauteil über einen Anschlussflansch problemlos an das erste Bauteil anschließbar.
Der Anschlussflansch weist dabei eine Nut zur Aufnahme eines Dichtmittels auf.
Der Anschlussflansch verhindert, insbesondere in Verbindung mit einem entsprechenden Dichtmittel, vorzugsweise einer O-Dichtung, dass Falschluft in den Faserleitkanal eintreten kann.
Das heißt, durch den Anschlussflansch kann sichergestellt werden, dass innerhalb der Kanalabschnittsteile des Faserleitkanals eine weitestgehend ungestörte Saugluftströmung ansteht, was für einen gleichmäßigen pneumatischen Transport der durch die Auflösewalze ausgekämmten Einzelfasern unerlässlich ist.As described in claims 2 and 3, the second component can be easily connected to the first component via a connecting flange.
The connection flange has a groove for receiving a sealant.
The connection flange prevents, in particular in conjunction with a corresponding sealing means, preferably an O-seal, that false air can enter the Faserleitkanal.
That is, it can be ensured by the connection flange that within the channel section parts of the fiber guide channel a largely undisturbed Saugluftströmung is pending, which is essential for a uniform pneumatic transport of the combed out by the opening roller individual fibers.

Wie im Anspruch 4 dargelegt, besitzt auch bei einem zweiteiligen Faserleitkanaleinsatz das zweite Bauteil des Faserleitkanaleinsatzes im Ausgangsbereich des Kanalabschnitts eine konkave gewölbte Dichtfläche.
Wie im Zusammenhang mit einem einteiligen Faserleitkanaleinsatz bereits erläutert, korrespondiert diese Dichtfläche mit einem zugehörigen Kanalplattenadapter und sorgt dafür, dass im Übergangsbereich zwischen den Kanalabschnitten ein sauberer pneumatischer Übergang gegeben ist.As set forth in claim 4, even in a two-part Faserleitkanaleinsatz the second component of Faserleitkanaleinsatzes in the exit region of the channel portion has a concave curved sealing surface.
As already explained in connection with a one-piece Faserleitkanaleinsatz, this sealing surface corresponds with an associated channel plate adapter and ensures that in the transition region between the channel sections a clean pneumatic transition is given.
