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
Offenend-Rotorspinnvorrichtungen mit zweiteiligen Faserleitkanälen sind bekannt und in zahlreichen Patentschriften, beispielsweise in der
Bei derartig ausgebildeten Faserleitkanälen ist der ausgangsseitige Kanalabschnitt vorzugsweise in einen Kanalplattenadapter integriert, der seinerseits auswechselbar in einer entsprechenden Aufnahme eines Deckelelementes angeordnet ist.
Der lagegenau in der Aufnahme des Deckelelementes angeordnete Kanalplattenadapter ragt während des Spinnbetriebes mit einem turmartigen Ansatz, der neben der Mündung des Faserleitkanals auch eine durchgängige Mittelbohrung zum Festlegen einer Fadenabzugsdüse aufweist, in den umlaufenden Spinnrotor.In fiber guide channels formed in this way, the output-side channel section is preferably integrated in a channel plate adapter, which in turn is interchangeably arranged in a corresponding receptacle of a cover element.
The precise position in the recording of the lid member arranged channel plate adapter projects during the spinning operation with a tower-like approach, which in addition to the mouth of Faserleitkanals also has a central through hole for fixing a thread take-off, in the rotating spinning rotor.
Das Deckelelement, das Lagerkonsolen für eine Auflösewalze und einen Faserbandzuführzylinder aufweist, verschließt während des Spinnprozesses ein nach vorne hin an sich offenes, unterdruckbeaufschlagbares Rotorgehäuse, in dem der Spinnrotor mit hoher Drehzahl rotiert.
Außerdem weist das Deckelelement ein Auflösewalzengehäuse auf 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 über die Lagerung und den Antrieb für den Spinnrotor verfügt.The cover element, which has bearing brackets for an opening roller and a sliver feed cylinder, closes during the spinning process a forwardly open, unterdruckbeaufschlagbarer rotor housing in which the spinning rotor rotates at high speed.
In addition, the lid member has an opening roller housing and is connected via a pivot axis which is arranged orthogonal to the axes of rotation of opening roller and Faserbandzuführzylinder limited movably connected to an associated spin box housing, for example, has the storage and the drive for the spinning rotor.
Der eingangsseitige Kanalabschnitt des Faserleitkanals ist bei derartig ausgebildeten zweiteiligen Faserleitkanälen in der Regel in ein Spritzgussteil integriert, das seinerseits in einer Aufnahmebohrung des Auflösewalzengehäuses angeordnet ist.The input-side channel portion of the fiber guide channel is in such formed two-part Faserleitkanälen in the Usually integrated in an injection molded part, which in turn is arranged in a receiving bore of the opening roller housing.
In derartigen Offenend-Rotorspinnvorrichtungen werden die von der Auflösewalze aus einem Vorlage-Faserband ausgekämmten Einzelfasern über den Faserleitkanal zum umlaufenden Spinnrotor befördert und von diesem zu einem fortlaufend abziehbaren Faden versponnen.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 the fiber guide channel to the revolving spinning rotor and are spun by it into a continuously removable thread.
Im Zusammenhang mit Offenend-Rotorspinnvorrichtungen ist es außerdem bekannt, dass Offenend-Rotorgarne von guter Qualität nur dann hergestellt werden können, wenn gewisse Randbedingungen, insbesondere bezüglich der gegenseitigen Anordnung und Dimensionierung der Spinnelemente erfüllt sind.
Die Gestaltung und Anordnung des Faserleitkanals, insbesondere der Abstand der Mündung des Faserleitkanals zur Faserrutschfläche des Spinnrotors, haben beispielsweise einen nicht unerheblichen Einfluss auf die erzielbare Garnqualität. Im Interesse optimaler Spinnergebnisse ist es daher vorteilhaft, jedem Spinnrotor, abhängig von dessen Durchmesser, einen speziellen Kanalplattenadapter zuzuordnen, dessen turmartiger Ansatz insbesondere bezüglich seines Durchmessers auf den jeweiligen Spinnrotor abgestimmt ist.
Das bedeutet in der Praxis, dass, wenn zum Beispiel im Zuge eines Garnpartiewechsels ein Austausch der Spinnrotoren vorgenommen wird, auch ein entsprechender Wechsel der Kanalplattenadapter stattfindet.In connection with open-end rotor spinning devices, it is also known that open-end rotor yarns of good quality can only be produced if certain boundary conditions, in particular with regard to the mutual arrangement and dimensioning of the spinning elements, are fulfilled.
The design and arrangement of the fiber guide channel, in particular the distance of the mouth of the fiber guide channel to the fiber slide surface of the spinning rotor, for example, have a not inconsiderable influence on the achievable yarn quality. In the interest of optimum spinning results, it is therefore advantageous to assign each spinning rotor, depending on its diameter, a special channel plate adapter whose tower-like approach is tuned in particular with respect to its diameter to the respective spinning rotor.
This means in practice that when, for example, in the course of a Garnpartiewechsels an exchange of the spinning rotors is made, also a corresponding change of the channel plate adapter takes place.
Es ist des Weiteren bekannt, dass auch durch die Gestaltung des Faserleitkanals sowie durch den Winkel, unter dem die Faseraufspeisung auf die Faserrutschfläche des Spinnrotors stattfindet, die Garnqualität positiv beeinflusst werden kann.It is furthermore known that the yarn quality can also be positively influenced by the design of the fiber guide channel and by the angle at which the fiber feed onto the fiber slide surface of the spinning rotor takes place.
In der
Versuche mit unterschiedlich großen Spinnrotoren und den zugehörigen Kanalplattenadaptern haben gezeigt, dass mit zweiteiligen Faserleitkanälen die besten textilphysikalischen Werte insbesondere dann erzielbar sind, wenn der Winkel zwischen den Mittellängslinien der Kanalabschnitte einen bestimmten Wert aufweist.Experiments with different sized spinning rotors and the associated channel plate adapters have shown that with two-part fiber guide channels the best textile-physical values can be achieved, in particular, if the angle between the center longitudinal lines of the channel sections has a specific value.
Wie vorstehend bereits angedeutet, stellt ein weiteres spinntechnisch relevantes Kriterium der so genannte Einspeisewinkel dar, das heißt, der Winkel, unter dem die über den Faserleitkanal herangeführten Einzelfasern auf eine mit hoher Drehzahl rotierende Faserrutschfläche des Spinnrotors aufgespeist werden.
Der Einspeisewinkel ergibt sich dabei aus der Lage des im Kanalplattenadapter angeordneten ausgangsseitigen Kanalabschnittes und ist zu mindest teilweise durch die Größe des turmartigen Ansatzes des Kanalplattenadapters vorgegeben.
Da der Einspeisewinkel eine bestimmte Größe jedoch nicht unter- bzw. überschreiten sollte, ergaben sich bei den bekannten zweiteiligen Faserleitkanälen bislang zwangsläufig, abhängig von der jeweiligen Größe des turmartigen Ansatzes des Kanalplattenadapters, unterschiedliche, zum Teil wenig vorteilhafte Winkel zwischen den Mittellängslinien der Kanalabschnitte des Faserleitkanals.As already indicated above, another criterion relevant to spinning technology is the so-called feed-in angle, that is, the angle at which the individual fibers brought up via the fiber guide channel are fed onto a fiber slide surface of the spinning rotor rotating at high speed.
The feed angle results from the position of the channel plate adapter arranged in the output side channel section and is at least partially determined by the size of the tower-like approach of the channel plate adapter.
However, since the feed angle should not fall below or exceed a certain size, the previously known two-part fiber guide channels inevitably had different, sometimes less advantageous angles between the central longitudinal lines of the channel sections of the fiber guide channel, depending on the respective size of the tower-like approach of the channel plate adapter ,
Es ist daher bereits vorgeschlagen worden, die bekannten Offenend-Rotorspinnvorrichtungen dahingehend zu modifizieren, dass unabhängig von der jeweiligen Größe des turmartigen Ansatzes des eingesetzten Kanalplattenadapters sowohl ein vorschriftsmäßiger Fasereinspeisewinkel eingehalten, als auch zwischen den Mittellängslinien der Kanalabschnitte des Faserleitkanals ein bestimmter, vorteilhafter Winkel realisiert werden kann.It has therefore already been proposed to modify the known open-end rotor spinning devices to the effect that regardless of the size of the tower-like approach of the channel plate adapter used both adhered to a proper fiber feeding, as well as between the central longitudinal lines of the channel sections of Faserleitkanals a certain, advantageous angle can be realized can.
In der
Der eingangsseitige Kanalabschnitt ist dabei in ein Spritzgussteil integriert, das seinerseits in einer Aufnahmebohrung des Auflöswalzengehäuses festgelegt ist.
Das Auflösewalzengehäuse, und damit der eingangsseitige Kanalabschnitt des Faserleitkanals, kann bezüglich des Deckelelements in zwei Ebenen geschwenkt werden, während der ausgangsseitige Kanalabschnitt in einen Kanalplattenadapter integriert ist, der in einer vorgegebenen Einbaulage im Deckelelement fixiert ist.
Das heißt, abhängig von der Größe des turmartigen Ansatzes des Kanalplattenadapters und damit von der Lage der Mittellängsachse des ausgangsseitigen Kanalabschnittes kann durch Verschwenken des gesamten Auflösewalzengehäuses die Mittellängslinie des eingangsseitigen Kanalabschnittes so positioniert werden, dass der Winkel zwischen den Kanalabschnitten einen bestimmten, vorteilhaften Wert einnimmt.In the
The input-side channel portion is integrated into an injection molded part, which in turn is fixed in a receiving bore of the dissolving roller housing.
The opening roller housing, and thus the input-side channel section of the fiber guide channel, can be pivoted with respect to the cover element in two planes, while the output-side channel section is integrated into a channel plate adapter, which is fixed in a predetermined mounting position in the cover element.
That is, depending on the size of the tower-like approach of the channel plate adapter and thus the position of the central longitudinal axis of the output-side channel section can be positioned by pivoting the entire opening roller housing the central longitudinal line of the input-side channel section so that the angle between the channel sections occupies a certain advantageous value.

Ausgehend von Offenend-Spinnvorrichtungen der vorstehend beschriebenen Gattung liegt der Erfindung die Aufgabe zugrunde, derartige Offenend-Rotorspinnvorrichtungen zu verbessern, insbesondere im Bereich des zweiteiligen Faserleitkanals dahingehend zu modifizieren, dass der Platzbedarf solcher Offenend-Rotorspinnvorrichtung ohne Verlust ihrer spinntechnologischen Vorteile minimiert ist.Starting from open-end spinning devices of the type described above, the invention has the object to improve such open-end rotor spinning, in particular in the area of the two-part Faserleitkanals to modify so that the space requirement of such open-end rotor spinning device is minimized without loss of their spinning technological advantages.
Diese Aufgabe wird erfindungsgemäß durch eine Offenend-Rotorspinnvorrichtung gelöst, wie sie im kennzeichnenden Teil des Anspruches 1 beschrieben ist.This object is achieved by an open-end rotor spinning device, as described in the characterizing part of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die im Anspruch 1 beschriebene, erfindungsgemäße Lagerung eines Kanalplattenadapters hat den Vorteil, dass nach einem Austausch des Spinnmittels, beispielsweise infolge eines Wechsels der Garnpartie, unabhängig von der Größe des turmartigen Ansatzes des Kanalplattenadapters, der Kanalplattenadapter auf einfache Weise stets so positioniert werden kann, dass ein bestimmter, vorteilhafter Winkel zwischen den Mittellängsachsen der beiden Kanalabschnitte eingestellt ist und damit optimale Strömungsverhältnisse innerhalb des Faserleitkanals gewährleistet sind.The inventive storage of a channel plate adapter described in
Die begrenzt drehbare Lagerung des Kanalplattenadapters bietet dabei nicht nur die Möglichkeit, den Neigungswinkel zwischen den Kanalabschnitten eines Faserleitkanals definiert einzustellen, sondern führt auch zu einer Offenend-Rotorspinnvorrichtung, die sich durch einen äußerst kompakten Aufbau auszeichnet.The limited rotatable mounting of the channel plate adapter not only offers the possibility of defining the angle of inclination between the channel sections of a fiber guide channel defined, but also leads to an open-end rotor spinning device, which is characterized by an extremely compact design.
Außerdem bietet die begrenzt drehbare Lagerung des Kanalplattenadapters bei Bedarf auch die Möglichkeit, gezielt in den Strömungsverlauf der innerhalb des Faserleitkanals wirksamen Transportluftströmung einzugreifen, um gegebenenfalls durch Änderung des Neigungswinkels die Strömungsverhältnisse zu optimieren und damit die textilphysikalischen Werte des herzustellenden Garnes zu verbessern.In addition, the limited rotatable mounting of the channel plate adapter, if necessary, also offers the possibility of specifically intervening in the flow course of the transport air flow acting within the fiber guide channel in order to optimize the flow conditions, if necessary by changing the angle of inclination, and thus to improve the textile-physical values of the yarn to be produced.
Wie im Anspruch 2 beschrieben, ist in vorteilhafter Ausführungsform vorgesehen, dass der Kanalplattenadapter, bezogen auf die optimale Einbaulage eines Kanalplattenadapters, dessen turmartiger Ansatz eine mittlere Größe aufweist, jeweils um einen Winkel schwenkbar gelagert sind, der zwischen + 10° und - 10° beträgt.
Das bedeutet, ein Kanalplattenadapter für einen im Durchmesser relativ großen Spinnrotor und entsprechend einem turmartigen Ansatz mit großem Durchmesser kann zur Einstellung eines optimalen Neigungswinkels zwischen den Kanalabschnitten des Faserleitkanals beispielsweise um bis zu 10° im Uhrzeigersinn geschwenkt werden.
Entsprechend kann ein Kanalplattenadapter für einen im Durchmesser relativ kleinen Spinnrotor beispielsweise um bis zu 10° im Gegenuhrzeigersinn gedreht werden.As described in
That is, a channel plate adapter for a relatively large diameter spinning rotor and a tower-like large diameter approach can be pivoted, for example, up to 10 ° clockwise to set an optimum angle of inclination between the channel sections of the fiber guide channel.
Accordingly, a channel plate adapter for a relatively small diameter spinning rotor, for example, be rotated by up to 10 ° counterclockwise.
Vorzugsweise weist der Kanalplattenadapter, wie im Anspruch 3 beschrieben, im Eingangsbereich des ausgangsseitigen Kanalabschnittes ein Anschlussmittel auf, das im Einbauzustand über ein elastisches Zwischenelement an den Ausgangsbereich eines eingangsseitigen Kanalabschnitts des Faserleitkanals angeschlossen ist.
Das Anschlussmittel stellt dabei in Verbindung mit dem elastischen Zwischenelement sicher, dass, egal in welche Richtung die beiden Kanalabschnitte des Faserleitkanals geschwenkt werden, innerhalb des Faserleitkanals stets ein ordnungsgemäßer Fasertransport, insbesondere ein sauberer Übergang der Fasern vom eingangseitigen Kanalabschnitt in den ausgangsseitigen Kanalschnitt, gegeben ist.Preferably, the channel plate adapter, as described in
The connection means in conjunction with the elastic intermediate element ensures that, no matter in which direction the two channel sections of the fiber guide channel are swiveled, a proper fiber transport, in particular a clean transition of the fibers from the input side channel section into the output side channel section, is always given within the fiber guide channel ,
In vorteilhafter Ausführungsform ist dabei, wie im Anspruch 4 beschrieben, der Mündungsbereich des elastischen Zwischenelementes kugelgelenkartig ausgebildet und korrespondiert mit einem kalottenartig ausgebildeten Endbereich am Anschlussmittel des Kanalplattenadapters.
Das heißt, das Zwischenelement und das Anschlussmittel bilden im Kontaktbereich der beiden Kanalabschnitte des Faserleitkanals einen gelenkkugelartig ausgebildeten Schwenkpunkt.
Durch eine solche Ausbildung lässt sich einerseits eine hohe Beweglichkeit und genaue Führung der beiden Kanalabschnitte des Faserleitkanals zueinander erreichen und anderseits auf relativ einfache Weise ein sauberer Übergang für die Fasern realisieren.In an advantageous embodiment, as described in
That is, the intermediate element and the connection means form in the contact region of the two channel sections of the fiber guide channel a pivot point formed pivot point.
Such a design makes it possible on the one hand to achieve high mobility and precise guidance of the two channel sections of the fiber guide channel relative to one another and, on the other hand, to realize a clean transition for the fibers in a relatively simple manner.
Um die beim Verschwenken des Kanalplattenadapters im Bereich des Faserleitkanals auftretenden Längenänderungen ausgleichen zu können, ist das elastische Zwischenelement außerdem, wie in Anspruch 5 dargelegt, bezüglich des eingangsseitigen Kanalabschnittes des Faserleitkanals axial verschiebbar angeordnet und passt sich somit automatisch an jede Längenänderung des Faserleitkanals an.In order to compensate for the changes in length occurring during pivoting of the channel plate adapter in the region of the fiber guide channel, the elastic intermediate element is, as set forth in
Wie im Anspruch 6 beschrieben, weist das Deckelelement eine Einstell- und Arretierungseinrichtung mit zum Beispiel einer Kanalplattenadapter entsprechend der Größe seines turmartigen Ansatzes jeweils exakt in einer vorteilhaften Einbaulage festlegbar ist.
In dieser Einbaulage ist der Kanalplattenadapter dann, unabhängig von der Größe seines turmartigen Ansatzes, stets so ausgerichtet, dass ein optimaler Neigungswinkel zwischen den beiden Kanalabschnitten des Faserleitkanals gegeben ist.
Die von der Größe des turmartigen Ansatzes des Kanalplattenadapters abhängige Raststellung für die jeweils optimale Einbaulage wurde dabei vorzugsweise bereits im Vorfeld ermittelt und ist beispielsweise durch eine entsprechende Markierung auf dem Deckelelement gekennzeichnet.As described in
In this installation position, the channel plate adapter is then, regardless of the size of its tower-like approach, always oriented so that an optimal angle of inclination between the two channel sections of the fiber guide channel is given.
The depending on the size of the tower-like approach of the channel plate adapter detent position for each optimal mounting position was preferably determined in advance and is characterized for example by a corresponding mark on the lid member.
Wie im Anspruch 7 dargelegt, ist in vorteilhafter Ausführungsform außerdem vorgesehen, dass der Kanalplattenadapter jeweils ein Positioniermittel aufweist, das im Einbauzustand des Kanalplattenadapters mit der Einstell- und Arretierungseinrichtung am Deckelelement korrespondiert.
Das heißt, ein am Kanalplattenadapter angeordnetes Positioniermittel rastet beispielsweise in die am Deckelelement angeordnete Einstell- und Arretierungseinrichtung ein und legt den Kanalplattenadapter dabei in einer vorteilhaften Einbaulage fest.As set forth in
That is, a positioning means arranged on the channel plate adapter engages, for example, in the adjusting and locking device arranged on the cover element and fixes the channel plate adapter in an advantageous installation position.
Der Kanalplattenadapter ist entweder in einer Aufnahme des Deckelelementes angeordnet und in dieser Aufnahme bezüglich seiner Mittenachse begrenzt drehbar gelagert oder der Kanalplattenadapter ist, wie im Anspruch 8 beschrieben, drehfest in einem speziellen Einsatz festgelegt.
Der Einsatz ist seinerseits begrenzt drehbar in einer Ausnehmung des Deckelelementes gelagert und weist neben einer Aufnahme für den Kanalplattenadapter eine umlaufende Ringdichtung auf, die bei geschlossenem Rotorgehäuse an der Vorderwand des Rotorgehäuses anliegt und das Rotorgehäuse abdichtet.The channel plate adapter is either arranged in a receptacle of the cover element and limited rotatably mounted in this recording with respect to its central axis or the channel plate adapter, as described in
The insert is in turn limited rotatably mounted in a recess of the cover member and has a receptacle for the channel plate adapter on a circumferential ring seal, which rests with the rotor housing closed on the front wall of the rotor housing and seals the rotor housing.
Auch bei der Verwendung eines solchen speziellen Einsatzes ist am Deckelelement eine Einstell- und Arretierungseinrichtung vorgesehen, die entsprechend der Größe des turmartigen Ansatzes des jeweiligen Kanalplattenadapters die vorteilhafte Einbaulage des Einsatzes und damit die optimale Einbaulage des Kanalplattenadapters vorgibt (Anspr.9).Even with the use of such a special use, an adjustment and locking device is provided on the cover element, which according to the size of the tower-like approach of the respective channel plate adapter, the advantageous installation position of the insert and thus the optimal installation position of the channel plate adapter specifies (Anspr.9).
Wie im Anspruch 10 dargelegt, korrespondiert im Einbauzustand des Einsatzes die Einstell- und Arretiereinrichtung am Deckelelement mit einem am Einsatz angeordneten Positioniermittel.
Das heißt, auch das am Einsatz angeordnete Positioniermittel rastet im Einbauzustand in die am Deckelelement angeordnete Einstell- und Arretierungseinrichtung ein und fixiert damit den jeweiligen Kanalplattenadapter in einer vorteilhaften Einbaulage.As set forth in
That is, also arranged on the insert positioning locks in the installed state in the arranged on the lid member adjustment and locking device and thus fixes the respective channel plate adapter in an advantageous installation position.
Wie im Anspruch 11 beschrieben, ist in vorteilhafter Ausführungsform vorgesehen, dass das Auflösewalzengehäuse schwenkbar gelagert ist, wobei der mögliche Schwenkwinkel, bezogen auf eine neutrale Mittelstellung, vorzugsweise zwischen + 10° und - 10° beträgt.
Das heißt, das Auflösewalzengehäuse ist in einer zur Frontseite des Auflösewalzengehäuses parallel verlaufenden Ebene verstellbar und kann mittels einer entsprechenden Arretierungseinrichtung definiert in vorgegebenen Einbaulagen fixiert werden.
Durch eine solche schwenkbare Lagerung des Auflösewalzengehäuses und damit auch des eingangsseitigen Kanalabschnittes des Faserleitkanals ist nicht nur ein guter Übergang für die Fasern im Übergangsbereich der Kanalabschnitte zu realisieren, sondern es wird auf einfache Weise auch der nutzbare Einstellbereich für den Neigungswindel zwischen den Kanalabschnitten verdoppelt.As described in
That is, the opening roller housing is adjustable in a direction parallel to the front side of the opening cylinder housing level and can be defined by means of a corresponding locking device fixed in predetermined mounting positions.
By such a pivotable mounting of the opening cylinder housing and thus also the input-side channel portion of the fiber guide not only a good transition for the fibers in the transition region of the channel sections to realize, but it also easily doubles the usable adjustment range for the diaper inclination between the channel sections.
Die erfindungsgemäße Offenend-Rotorspinnvorrichtung verliert aufgrund des relativ kleinen Schwenkwinkels des Auflösewalzengehäuses dabei weder ihre kompakte Bauweise, noch kommt es zu einem Verlust der guten Handhabbarkeit der Offenend-Rotorspinnvorrichtung.The open-end rotor spinning device according to the invention loses neither its compact design due to the relatively small pivoting angle of the opening roller housing, nor does it result in a loss of good handleability of the open-end rotor spinning device.
