Definitions
- the invention relates to a drafting system for warping a roving according to the preamble of claim 1.
- Draw frames for warping rovings are widely used in the textile industry and are used on various textile machines.
- the work stations of ring spinning machines are equipped, for example, with drafting devices which draw a roving unwound from a flyer bobbin into a sliver of high fineness, which is then provided with a twist and wound up as a finished yarn on a spinning cop.
- Such drafting systems usually have three machine-length, driven by a machine end side drive at different rotational speeds, spaced arranged lower rollers, and each three associated, arranged on a pivotally mounted pendulum carrier top rollers.
- the top rollers lie during the spinning operation with a predetermined contact pressure on the driven bottom rollers and are driven by these frictionally. That is, the upper rollers form with the associated lower rollers roller pairs, which ensure because of their different rotational speeds that the submitted roving is distorted when passing through the drafting system.
- such drafting systems typically include an input, a center and an output roller pair, with the area between the input and center roller pairs forming a so-called biasing field, while the range between the middle and the output roller pair acts as a main drafting field.
- the supplied roving is warped in the drafting to the desired fineness and leaves the drafting at the nip of the pair of delivery rollers as a relatively wide, for example, up to 50 times warped sliver.
- this relatively wide sliver is subsequently subjected to spin rotation at the relevant workstation by a spinning spinning cop in conjunction with an associated ring traveler and thereby twisted into a finished yarn.
- the output top rollers arranged in front of the compaction zone and the upper top delivery rollers arranged downstream of the compaction zone are mounted in a common cage element in such a way that the axes of the roller pairs are guided parallel to one another. That is, the cage element covered with its first axis guide means the axis of the top rollers at the side of the saddle, which in turn is arranged in a so-called output link of the pendulum carrier and held there by a saddle spring.
- the output link is usually acted upon by a spring element so that the Ninoberwalzen rest with a defined contact pressure on the associated output lower rollers.
- the delivery top rollers must also rest on the delivery bottom rollers with a specific loading force, since this is the only way to ensure that the compacted fibers are properly transported even in the area of the compression zone.
- various methods or devices are known.
- the utility model CN 2 765 913 Y discloses a ring spinning machine with a pressurized fiber compaction device.
- the utility model includes a pair of delivery rollers wherein the exit top roller comprises a strap.
- the utility model has a compacting swirl stop element which has a suction roll and a compacting apron.
- the suction roll is provided with a suction slot and coated with an air-permeable conveyor belt.
- the compacting swirl stop element is arranged after the pair of output rollers.
- Both the apron and the conveyor belt are each arranged on cage elements.
- a pressurized spring is disposed between the apron cage and a support beam mounted on the shuttle carrier.
- the Riemchen tanninfig is provided with a receptacle for the spring, wherein the spring guide rests against the Abstützbalken the pendulum carrier.
- the device is intended to effectively capture and densify the fibers so that the sliver can be compacted and twisted into a yarn.
- the CN 100 564 626 C refers to a ring spinning machine with a compacting device.
- the drafting system in addition to an input, middle and output roller pair on a delivery roller pair.
- the delivery sub-roller is arranged so that it is both in contact with the réelleoberwalze and the Kayoberwalze.
- the contact pressure of the delivery sub-roller relative to the top and the delivery top roller can be varied.
- the cage element with a molded surface, which is arranged and designed so that the cage element in the installed state and with closed pendulum carrier on the underside of the output link ab- supports. That is, the loading force introduced from the output link is transmitted to the cage member via the integrally formed surface and distributed to the output top rollers and the delivery top rollers at respective intervals.
- a disadvantage of this known type of connection of delivery top rollers is, inter alia, that the output top rollers are often dug out of their leadership and receiving device in the cage element, with the result that the top rollers are no longer exactly out, which in principle to a deterioration of the yarn quality leads.
- Retrofitting of the known drafting systems for example, by a significant increase in the maximum load force of the output link, brought no lasting success, since such a significant increase in the loading force not only led to settlement effects on the top rollers, which also has a negative effect on the achievable yarn quality, but also a defined setting of the optimal loading force of the top roller pairs very difficult.
- Such additional leaf spring can either, as in the DE 100 05 387 A1 described, attached to the pendulum carrier of the drafting system, for example via a screw connection, or, as by the DE 10 2009 050 581 A1 known to be stationarily arranged on the cage element.
- the present invention seeks to further develop a drafting system for warping roving so that during the spinning operation in the delivery top rollers counting to the compression zone, which are stored in a cage element, which in turn is acted upon by a pressure element, always a almost constant loading force can be guaranteed.
- the inventive construction in which the pressure element is a longitudinally variable in length formed spring element which is supported at its two ends in each case articulated to bearings not only has the advantage that not only in a simple manner, a relatively large loading force by such an embodiment the cage element, especially on the delivery top rollers mounted in the cage element, can be transferred, but such a design and arrangement of a pressure element can also ensure that, even if the delivery top rollers do not have an exact concentricity, as hitherto conventional in the prior art , comes to the occurrence of any harmful stress fluctuations.
- variable-length pressure element that easily compensates for any angular and / or positional changes its bearings, it is reliably prevented that it comes during operation of the drafting between the pressure element and the cage member to harmful relative movements. That is, the use of a pressure element, which has the inventive construction and arrangement, can be ensured in a relatively simple manner that it can not come to the occurrence of harmful static friction forces during operation of the drafting system.
- the pressure element is designed as a helical compression spring which is connected on the one hand articulated to the pendulum carrier of the drafting system and on the other hand hinged to the cage element.
- helical compression springs are in mechanical engineering for a long time proven mass-produced components that are economically available in almost all sizes and strengths and due to their structural design and side pressure components easily, that is, compensate virtually frictionless.
- the cage element has in the region of a guide and receiving means for the axis of Dolphinoberwalzencrues equipped with a guide pin connection device for supporting and adjusting the helical compression spring.
- a connection device with guide pin allows a simple way of accurate compliance with the loading direction of the force introduced by the helical compression spring loading force.
- the arrangement of the connection device in the region of the guide and receiving device for the axis of Kayoberwalzencrues also ensures that the loading force is transmitted for the most part directly to the Kayoberwalzencru.
- a cage element equipped with such a connection device also represents a cost-effective, reliable component which ensures proper spinning operation over a long period of time.
- a receiving device for the helical compression spring is arranged on the pendulum carrier, wherein the receiving device is attached via an axle on the pendulum carrier.
- the single FIGURE shows a drafting 1 for warping roving, wherein a drafting zone 30 of the drafting 1 is connected downstream of a compression zone 10, the supplied in a cage member 25 delivery roller pair 11o is acted upon by a pressure element which is formed in an advantageous embodiment as a helical compression spring 15.
- the drafting unit 1 shown has, as is known, an input roller pair 2, a middle roller pair 3 and an output roller pair 4, wherein the roller pairs 2, 3, 4 are each formed by bottom rollers and associated top rollers.
- the usually machine-length, for example, by a machine end side arranged drive and a corresponding gear assembly with different rotational speeds driven lower rollers 2u, 3u, 4u are stored on (not shown) punching on the machine frame of a ring spinning machine, while the top rollers 2o, 3o, 4o, during of the spinning operation are frictionally driven by the lower rollers, each connected via so-called handlebars to a pendulum carrier 5, which in turn is fixed via a support 28 to a support rod 12 fixed to the machine frame.
- the pendulum carrier 5 of the numerous drafting 1 can each be positioned by means of an operating lever 6 in the positions “drafting system loaded” or “drafting system loaded”, with a third position "drafting system relieved” adjusts when the top rollers rest on the bottom rollers without the Control lever 6 is in its closed position.
- Such drafting units 1 have between the pair of input rollers 2 and the pair of output rollers 4, a draft zone 30 in which the supplied roving 26 is preferably warped up to 50 times its input length.
- the drafting zone 30 is divided into the intermediate delay zone 7 lying between the pair of input rollers 2 and the middle roller pair 3 and the main drafting zone 8 located between the middle roller pair 3 and the pair of delivery rollers 4.
- a compression zone 10 connects, which is located between the pair of output rollers 4 and the pair of delivery rollers 11.
- the skilletoberwalzencru 4o is connected via a spring-loaded output link 9 to the pendulum carrier 5 of the drafting system 1. That is, the axis 13 of réelleoberwalzencrues 4o is fixed with its saddle piece in a receptacle of the output link 9, preferably by a spring element ge, set.
- a first guide and receiving device 29 whose light diameter is slightly above the diameter of the axis 13, a cage member 25 mounted, in addition to this first guide and receiving device 29, a second guide and receiving device 31 for the axis 17 of the delivery upper roller pair 11o and a connection device 14 for Support and adjustment of the preferably formed as a helical compression spring pressure element 15 has.
- the connection device 14 is arranged in the region above the second guide and receiving device 31 for the axis 17 of the Dolphinoberwalzencrues 11o and has a guide pin 16 for the articulated positioning of the end 32 of the helical compression spring 15.

Description
Die Erfindung betrifft ein Streckwerk zum Verziehen eines Vorgarns gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a drafting system for warping a roving according to the preamble of
Streckwerke zum Verziehen von Vorgarnen sind in der Textilindustrie weit verbreitet und kommen an unterschiedlichen Textilmaschinen zum Einsatz.
Die Arbeitsstellen von Ringspinnmaschinen sind beispielsweise mit solchen Streckwerken ausgestattet, die ein von einer Flyerspule abgewickeltes Vorgarn zu einem Faserband von hoher Feinheit verziehen, das anschließend mit einer Drehung versehen und als fertiges Garn auf einen Spinnkops aufgewickelt wird.Draw frames for warping rovings are widely used in the textile industry and are used on various textile machines.
The work stations of ring spinning machines are equipped, for example, with drafting devices which draw a roving unwound from a flyer bobbin into a sliver of high fineness, which is then provided with a twist and wound up as a finished yarn on a spinning cop.
Derartige Streckwerke weisen in der Regel drei maschinenlange, von einem maschinenendseitig angeordneten Antrieb mit unterschiedlichen Rotationsgeschwindigkeiten angetriebene, beabstandet angeordnete Unterwalzen, sowie jeweils drei zugehörige, an einem schwenkbar gelagerten Pendelträger angeordnete Oberwalzen auf.
Die Oberwalzen liegen während des Spinnbetriebes mit einem vorgebbaren Auflagedruck auf den angetriebenen Unterwalzen und werden von diesen reibschlüssig angetrieben. Das heißt, die Oberwalzen bilden mit den zugehörigen Unterwalzen Walzenpaare, die aufgrund ihrer unterschiedlichen Rotationsgeschwindigkeiten dafür sorgen, dass das vorgelegte Vorgarn beim Durchlaufen des Streckwerkes verzogen wird.Such drafting systems usually have three machine-length, driven by a machine end side drive at different rotational speeds, spaced arranged lower rollers, and each three associated, arranged on a pivotally mounted pendulum carrier top rollers.
The top rollers lie during the spinning operation with a predetermined contact pressure on the driven bottom rollers and are driven by these frictionally. That is, the upper rollers form with the associated lower rollers roller pairs, which ensure because of their different rotational speeds that the submitted roving is distorted when passing through the drafting system.
Wie vorstehend angedeutet, weisen derartige Streckwerke in der Regel ein Eingangs-, ein Mittel- und ein Ausgangswalzenpaar auf, wobei der Bereich zwischen dem Eingangs- und dem Mittelwalzenpaar ein so genanntes Vorverzugsfeld bildet, während der Bereich zwischen dem Mittel- und dem Ausgangswalzenpaar als Hauptverzugsfeld fungiert.As indicated above, such drafting systems typically include an input, a center and an output roller pair, with the area between the input and center roller pairs forming a so-called biasing field, while the range between the middle and the output roller pair acts as a main drafting field.
Das zugeführte Vorgarn wird im Streckwerk auf die gewünschte Feinheit verzogen und verlässt das Streckwerk an der Klemmlinie des Ausgangswalzenpaares als relativ breites, zum Beispiel bis zu 50fach verzogenes Faserband.
Wie vorstehend bereits angedeutet, wird dieses relativ breite Faserband anschließend an der betreffenden Arbeitsstelle durch einen drehenden Spinnkops in Verbindung mit einem zugehörigen Ringläufer mit Spinndrehung beaufschlagt und dabei zu einem fertigen Garn verdrillt.
In der Praxis bedeutet das, dass sich im Anschluss an die Klemmlinie des Ausgangswalzenpaares ein so genanntes Spinndreieck bildet, in dem das aus dem Streckwerk austretende Faserband zusammengeführt und zu einer Garnstruktur verdrillt wird.
Da die Breite des verstreckten Faserbandes den Durchmesser des fertigen Garnes deutlich übersteigt, werden im Spinndreieck oft nicht alle Fasern in die Garnstruktur eingebunden bzw. nicht ordnungsgemäß eingebunden und stehen dann als Randfasern vom fertigen Garn ab.The supplied roving is warped in the drafting to the desired fineness and leaves the drafting at the nip of the pair of delivery rollers as a relatively wide, for example, up to 50 times warped sliver.
As already indicated above, this relatively wide sliver is subsequently subjected to spin rotation at the relevant workstation by a spinning spinning cop in conjunction with an associated ring traveler and thereby twisted into a finished yarn.
In practice, this means that following the nip line of the pair of delivery rollers, a so-called spinning triangle is formed, in which the sliver emerging from the drafting system is brought together and twisted into a yarn structure.
Since the width of the drawn sliver significantly exceeds the diameter of the finished yarn, not all fibers are often integrated into the yarn structure or not properly incorporated in the spinning triangle and then stand as edge fibers from the finished yarn.
Um das Entstehen solcher Randfasern möglichst zu vermeiden, ist in der Vergangenheit im Zusammenhang mit Ringspinnmaschinen bereits vorgeschlagen worden, die Streckwerke solcher Textilmaschinen um eine so genannte Verdichtungszone zu ergänzen.
Das heißt, an die Ausgangswalzenpaare wurden beabstandet Lieferwalzenpaare angeschlossen, wobei das Lieferoberwalzenpaar, zum Beispiel durch eine zugehörige Lieferunterwalze, reibschlüssig rotiert wird. In alternativer Ausführungsform kann auch eine gemeinsame Unterwalze vorgesehen sein, die sowohl von der Ausgangsoberwalze, als auch von der Lieferoberwalze beaufschlagt wird, oder zum Antrieb der Lieferoberwalze kommt ein Getriebe oder ein Zugmitteltrieb zum Einsatz, das/der von der Ausgangsoberwalze angetrieben wird.
Zwischen den Ausgangswalzenpaaren und den Lieferwalzenpaaren sind außerdem spezielle Verdichtungseinrichtungen angeordnet, die zum Beispiel als mechanische Verdichter ausgebildet sein können oder auch pneumatisch arbeiten.
In der Regel sind die vor der Verdichtungszone angeordneten Ausgangsoberwalzen und die der Verdichtungszone nachgeordneten oberen Lieferoberwalzen in einem gemeinsamen Käfigelement so gelagert, dass die Achsen der Walzenpaare parallel zueinander geführt sind. Das heißt, das Käfigelement überfasst mit seiner ersten Achsführungseinrichtung die Achse der Ausgangsoberwalzen seitlich neben deren Sattelstück, das seinerseits in einem so genannten Ausgangslenker des Pendelträgers angeordnet und dort durch eine Sattelfeder gehalten ist.
Der Ausgangslenker wird üblicherweise durch ein Federelement so beaufschlagt, dass die Ausgangsoberwalzen mit einem definierten Auflagedruck auf den zugehörigen Ausgangsunterwalzen aufliegen. Während des Spinnbetriebes müssen auch die Lieferoberwalzen mit einer bestimmten Belastungskraft auf den Lieferunterwalzen aufliegen, da nur so gewährleistet werden kann, dass die verdichteten Fasern auch im Bereich der Verdichtungszone ordnungsgemäß transportiert werden. Um diese für einen ordnungsgemäßen Betrieb der Verdichtungszone zwingend notwendige Belastungskraft zu erzeugen, sind verschiedene Methoden bzw. Vorrichtungen bekannt.To avoid the emergence of such edge fibers as possible, has already been proposed in the past in connection with ring spinning machines to supplement the drafting of such textile machines to a so-called compression zone.
That is, delivery roller pairs have been spacedly connected to the exit roller pairs with the delivery top roller pair being frictionally rotated by, for example, an associated delivery sub-roller. In an alternative embodiment, a common lower roller may be provided, which is acted upon by both the Ausgangsoberwalze, as well as by the delivery upper roller, or To drive the delivery top roller is a gear or a traction drive is used, which is driven by the Ausgangsoberwalze.
Between the pairs of output rollers and the pair of delivery rollers special compression means are also arranged, which may be formed, for example, as a mechanical compressor or work pneumatically.
In general, the output top rollers arranged in front of the compaction zone and the upper top delivery rollers arranged downstream of the compaction zone are mounted in a common cage element in such a way that the axes of the roller pairs are guided parallel to one another. That is, the cage element covered with its first axis guide means the axis of the top rollers at the side of the saddle, which in turn is arranged in a so-called output link of the pendulum carrier and held there by a saddle spring.
The output link is usually acted upon by a spring element so that the Ausgangsoberwalzen rest with a defined contact pressure on the associated output lower rollers. During the spinning operation, the delivery top rollers must also rest on the delivery bottom rollers with a specific loading force, since this is the only way to ensure that the compacted fibers are properly transported even in the area of the compression zone. In order to generate these mandatory for a proper operation of the compression zone loading force, various methods or devices are known.

Es ist aus der Praxis beispielsweise bekannt, das Käfigelement mit einer angeformten Fläche zu versehen, die so angeordnet und ausgebildet ist, dass sich das Käfigelement im Einbauzustand und bei geschlossenem Pendelträger an der Unterseite des Ausgangslenkers ab-stützt. Das heißt, die vom Ausgangslenker eingeleitete Belastungskraft wird über die angeformte Fläche auf das Käfigelement übertragen und entsprechend den jeweiligen Abständen auf die Ausgangsoberwalzen und die Lieferoberwalzen verteilt.It is known from practice, for example, to provide the cage element with a molded surface, which is arranged and designed so that the cage element in the installed state and with closed pendulum carrier on the underside of the output link ab- supports. That is, the loading force introduced from the output link is transmitted to the cage member via the integrally formed surface and distributed to the output top rollers and the delivery top rollers at respective intervals.
Nachteilig bei dieser bekannten Art der Anbindung von Lieferoberwalzen ist unter anderem, dass die Ausgangsoberwalzen dabei oft etwas aus ihrer Führungs- und Aufnahmeeinrichtung im Käfigelement ausgehoben werden, mit der Folge, dass die Ausgangsoberwalzen nicht mehr exakt geführt sind, was grundsätzlich zu einer Verschlechterung der Garnqualität führt.A disadvantage of this known type of connection of delivery top rollers is, inter alia, that the output top rollers are often dug out of their leadership and receiving device in the cage element, with the result that the top rollers are no longer exactly out, which in principle to a deterioration of the yarn quality leads.
Auch eine Nachrüstung der bekannten Streckwerke, zum Beispiel durch eine deutliche Erhöhung der maximalen Belastungskraft des Ausgangslenkers, brachte keinen nachhaltigen Erfolg, da eine solche deutliche Erhöhung der Belastungskraft nicht nur zu Setzungseffekten an den Oberwalzen führte, was sich ebenfalls negativ auf die erreichbare Garnqualität auswirkt, sondern auch eine definierte Einstellung der optimalen Belastungskraft der Oberwalzenpaare sehr erschwert.Retrofitting of the known drafting systems, for example, by a significant increase in the maximum load force of the output link, brought no lasting success, since such a significant increase in the loading force not only led to settlement effects on the top rollers, which also has a negative effect on the achievable yarn quality, but also a defined setting of the optimal loading force of the top roller pairs very difficult.
Um die Problematik der verminderten Führung der Ausgangsoberwalzen im Käfigelement zu beseitigen, ist deshalb in der Vergangenheit bereits vorgeschlagen worden, das Käfigelement durch eine zusätzliche Blattfeder extra zu belasten. Die solche zusätzliche Blattfeder kann dabei entweder, wie beispielsweise in der
In der Praxis hat sich allerdings herausgestellt, dass auch diese bekannten Vorrichtungen sehr nachteilig sind, wenn die Lieferunterwalzen, auf denen die Lieferoberwalzen während des Spinnbetriebs aufliegen, keinen exakten Rundlauf aufweisen.
In einem solchen Fall führt das Käfigelement, in dem die Lieferoberwalzen gelagert sind, eine Schwenkbewegung um die Ausgangsoberwalze aus, mit der Folge, dass es, beispielsweise bei einer am Pendelträger befestigten Belastungsfeder zwischen der Blattfeder und dem Käfigelement zu einer Relativbewegung kommt.
Die dabei zwischen der Blattfeder und dem Käfigelement auftretende Reibung führt zu einem Gegenmoment, das bei einer Abwärtsbewegung des Käfigelements zu einer Schwächung und bei einer Aufwärtsbewegung des Käfigelements zu einer Verstärkung der jeweils vorliegenden Belastungskraft führt. Das heißt, bei diesen bekannten Vorrichtungen ist die während des Spinnprozesses durch die Lieferoberwalzen zu übertragende Belastungskraft, wenn die Lieferunterwalzen keinen exakten Rundlauf aufweisen, nicht konstant, sondern schwankt, was sich negativ auf die Garnqualität auswirkt.In practice, however, it has been found that these known devices are also very disadvantageous if the delivery bottom rollers, on which the delivery top rollers rest during spinning, do not have an exact concentricity.
In such a case, the cage member, in which the delivery top rollers are mounted, performs a pivotal movement about the output top roller, with the result that, for example, when mounted on a pendulum carrier loading spring between the leaf spring and the cage member to a relative movement.
The friction occurring between the leaf spring and the cage element leads to a counter-moment, which leads to a weakening in a downward movement of the cage element and an upward movement of the cage element to an amplification of the respective existing loading force. That is, in these known devices, the loading force to be transmitted by the delivery top rollers during the spinning process is not constant but fluctuates when the delivery bottom rollers do not have an exact concentricity, which has a negative effect on the yarn quality.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Streckwerk zum Verziehen von Vorgarn so weiterzuentwickeln, dass während des Spinnbetriebes bei den zur Verdichtungszone zählenden Lieferoberwalzen, die in einem Käfigelement gelagert sind, das seinerseits durch ein Druckelement beaufschlagt wird, stets eine nahezu konstante Belastungskraft gewährleistet werden kann.Based on the aforementioned prior art, the present invention seeks to further develop a drafting system for warping roving so that during the spinning operation in the delivery top rollers counting to the compression zone, which are stored in a cage element, which in turn is acted upon by a pressure element, always a almost constant loading force can be guaranteed.
Diese Aufgabe wird erfindungsgemäß durch ein Streckwerk gelöst, das die im Anspruch 1 beschriebenen Merkmale aufweist.This object is achieved by a drafting system having the features described in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Ausbildung, bei der das Druckelement ein in seiner Längsrichtung längenveränderlich ausgebildetes Federelement ist, das an seinen beiden Enden jeweils gelenkig an Lagerstellen abgestützt ist, hat nicht nur den Vorteil, dass durch eine solche Ausführungsform nicht nur auf einfache Weise eine relativ große Belastungskraft auf das Käfigelement, speziell auf die im Käfigelement gelagerten Lieferoberwalzen, übertragen werden kann, sondern durch eine solche Ausbildung und Anordnung eines Druckelements kann auch sichergestellt werden, dass es, selbst wenn die Lieferoberwalzen keinen exakten Rundlauf aufweisen, nicht, wie beim Stand der Technik bislang üblich, zum Auftreten irgendwelcher schädlicher Belastungsschwankungen kommt.
Durch ein solches längenveränderliches Druckelement, das problemlos eventuellen Winkel- und/oder Lageänderungen seiner Lagerstellen ausgleicht, wird zuverlässig verhindert, dass es während des Betriebs des Streckwerkes zwischen dem Druckelement und dem Käfigelement zu schädlichen Relativbewegungen kommt.
Das heißt, durch den Einsatz eines Druckelements, welches die erfindungsgemäße Ausbildung und Anordnung aufweist, kann auf relativ einfache Weise sichergestellt werden, dass es während des Betriebes des Streckwerks nicht zum Auftreten von schädlichen Haftreibungskräften kommen kann.The inventive construction in which the pressure element is a longitudinally variable in length formed spring element which is supported at its two ends in each case articulated to bearings, not only has the advantage that not only in a simple manner, a relatively large loading force by such an embodiment the cage element, especially on the delivery top rollers mounted in the cage element, can be transferred, but such a design and arrangement of a pressure element can also ensure that, even if the delivery top rollers do not have an exact concentricity, as hitherto conventional in the prior art , comes to the occurrence of any harmful stress fluctuations.
By such a variable-length pressure element that easily compensates for any angular and / or positional changes its bearings, it is reliably prevented that it comes during operation of the drafting between the pressure element and the cage member to harmful relative movements.
That is, the use of a pressure element, which has the inventive construction and arrangement, can be ensured in a relatively simple manner that it can not come to the occurrence of harmful static friction forces during operation of the drafting system.
Gemäß Anspruch 2 ist in vorteilhafter Ausführungsform vorgesehen, dass das Druckelement als Schraubendruckfeder ausgebildet ist, die einerseits gelenkig an den Pendelträger des Streckwerkes und andererseits gelenkig an das Käfigelement angeschlossen ist.
Derartige Schraubendruckfedern stellen im Maschinenbau seit langem bewährte Großserienbauteile dar, die in nahezu allen Größen und Stärken kostengünstig erwerbbar sind und die aufgrund ihrer konstruktiven Ausbildung auch seitliche Druckkomponenten problemlos, das heißt, nahezu reibungsfrei ausgleichen.According to
Such helical compression springs are in mechanical engineering for a long time proven mass-produced components that are economically available in almost all sizes and strengths and due to their structural design and side pressure components easily, that is, compensate virtually frictionless.
Durch den Einsatz einer solchen Schraubendruckfeder kann folglich auf relativ sichere und kostengünstige Weise gewährleitet werden, dass während des Spinnbetriebes im Bereich der Verdichtungszone eines Streckwerkes bei nahezu allen Bedingungen, das heißt auch bei einem nicht ganz runden Lauf der Lieferunterwalzen, stets eine fast konstante Einleitung der an den Lieferoberwalzen benötigten Belastungskraft gegeben ist.The use of such a helical compression spring can thus be ensured in a relatively safe and cost-effective manner, that during the spinning operation in the compression zone of a drafting system in almost all conditions, that is, even at a not quite round run of Lieferunterwalzen, always an almost constant initiation of given on the delivery top rollers required loading force.
Wie im Anspruch 3 beschrieben, ist in bevorzugter Ausbildung vorgesehen, dass das Käfigelement im Bereich einer Führungs- und Aufnahmeeinrichtung für die Achse des Lieferoberwalzenpaares eine mit einem Führungszapfen ausgerüstete Anschlusseinrichtung zur Abstützung und Justierung der Schraubendruckfeder aufweist.
Eine solche Anschlusseinrichtung mit Führungszapfen ermöglicht auf einfache Weise eine genaue Einhaltung der Belastungsrichtung der durch die Schraubendruckfeder eingeleiteten Belastungskraft.
Die Anordnung der Anschlusseinrichtung im Bereich der Führungs- und Aufnahmeeinrichtung für die Achse des Lieferoberwalzenpaares sorgt außerdem dafür, dass die Belastungskraft zum größten Teil direkt auf das Lieferoberwalzenpaar übertragen wird.
Ein mit einer solchen Anschlusseinrichtung ausgestattetes Käfigelement stellt außerdem ein kostengünstiges, zuverlässiges Bauteil dar, das über einen langen Zeitraum einen ordnungsgemäßen Spinnbetrieb sicherstellt.As described in
Such a connection device with guide pin allows a simple way of accurate compliance with the loading direction of the force introduced by the helical compression spring loading force.
The arrangement of the connection device in the region of the guide and receiving device for the axis of Lieferoberwalzenpaares also ensures that the loading force is transmitted for the most part directly to the Lieferoberwalzenpaar.
A cage element equipped with such a connection device also represents a cost-effective, reliable component which ensures proper spinning operation over a long period of time.
Gemäß Anspruch 4 ist des Weiteren vorgesehen, dass am Pendelträger eine Aufnahmeeinrichtung für die Schraubendruckfeder angeordnet ist, wobei die Aufnahmeeinrichtung über eine Achse am Pendelträger befestigt ist.
Durch die am Pendelträger befestigte Aufnahmeeinrichtung für die Schraubendruckfeder wird nicht nur auf einfache Weise gewährleistet, dass die Schraubenfeder stets ordnungsgemäß am Pendelträger festlegbar ist, sondern die Aufnahmeeinrichtung stellt in Zusammenarbeit mit der am Käfigelement angeordneten Anschlusseinrichtung auch sicher, dass die Schraubendruckfeder während des Spinnbetriebes immer vorschriftsmäßig ausgerichtet ist.
Das bedeutet, aufgrund der ordnungsgemäßen Ausrichtung der eingebauten Schraubendruckfeder wird das Auftreten von Haftreibung zwischen Käfigelement und Schraubendruckfeder zuverlässig verhindert, so dass, wenn man die inneren Reibungskräfte der Schraubendruckfeder außer Acht lässt, eine quasi reibungsfreie Übertragung der durch die Schraubendruckfeder vorgegebenen Belastungskräfte auf die Lieferoberwalzen möglich ist.According to claim 4 is further provided that a receiving device for the helical compression spring is arranged on the pendulum carrier, wherein the receiving device is attached via an axle on the pendulum carrier.
By attached to the pendulum carrier receiving device for the helical compression spring is not only ensured in a simple manner that the coil spring always properly on pendulum carrier can be fixed, but the receiving device also ensures in cooperation with the arranged on the cage element connection device that the helical compression spring is always aligned properly during spinning operation.
This means that due to the proper orientation of the built-in helical compression spring the occurrence of static friction between the cage member and helical compression spring is reliably prevented, so that, if the internal friction forces of the helical compression spring is disregarded, a quasi-friction transmission of the predetermined by the helical compression spring loading forces on the delivery top rollers possible is.
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.
Die einzige Figur zeigt ein Streckwerk 1 zum Verziehen von Vorgarn, wobei einer Verzugszone 30 des Streckwerkes 1 eine Verdichtungszone 10 nachgeschaltet ist, deren in einem Käfigelement 25 gelagertes Lieferwalzenoberpaar 11o durch ein Druckelement beaufschlagt wird, das in vorteilhafter Ausführungsform als Schraubendruckfeder 15 ausgebildet ist.The single FIGURE shows a
Das dargestellte Streckwerk 1 verfügt, wie bekannt, über ein Eingangswalzenpaar 2, ein Mittelwalzenpaar 3 sowie ein Ausgangswalzenpaar 4, wobei die Walzenpaare 2, 3, 4 jeweils durch Unterwalzen und zugehörige Oberwalzen gebildet werden.
Die in der Regel maschinenlangen, beispielsweise durch einen maschinenendseitig angeordneten Antrieb sowie eine entsprechende Getriebeanordnung mit unterschiedlichen Rotationsgeschwindigkeiten angetriebenen Unterwalzen 2u, 3u,4u sind über (nicht dargestellte) Stanzen am Maschinengestell einer Ringspinnmaschine gelagert, während die Oberwalzen 2o, 3o, 4o, die während des Spinnbetriebes von den Unterwalzen reibschlüssig angetrieben werden, jeweils über so genannte Lenker an einen Pendelträger 5 angeschlossen sind, der seinerseits über eine Stütze 28 an einer am Maschinengestell befestigten Haltestange 12 festgelegt ist.The
The usually machine-length, for example, by a machine end side arranged drive and a corresponding gear assembly with different rotational speeds driven
Die Pendelträger 5 der zahlreichen Streckwerke 1 können jeweils mittels eines Bedienhebels 6 in den Stellungen "Streckwerk hochgeklappt" oder "Streckwerk belastet" positioniert werden, wobei sich eine dritte Stellung "Streckwerk entlastet" einstellt, wenn die Oberwalzen auf den Unterwalzen aufliegen, ohne dass der Bedienhebel 6 in seiner Schließstellung steht.The
Derartige Streckwerke 1 weisen zwischen dem Eingangswalzenpaar 2 und dem Ausgangswalzenpaar 4 eine Verzugszone 30 auf, in der das zugeführte Vorgarn 26 vorzugsweise bis zum 50fachen seiner Eingangslänge verzogen wird.
Die Verzugszone 30 ist dabei in das zwischen dem Eingangswalzenpaar 2 und dem Mittelwalzenpaar 3 liegende Vorverzugsfeld 7 und das zwischen dem Mittelwalzenpaar 3 und dem Ausgangswalzenpaar 4 liegende Hauptverzugsfeld 8 aufgeteilt.
An die Verzugszone 30 schließt sich eine Verdichtungszone 10 an, die zwischen dem Ausgangswalzenpaar 4 und dem Lieferwalzenpaar 11 liegt.
The drafting
At the
Wie aus der Figur ersichtlich, ist das Ausgangsoberwalzenpaar 4o über einen federbeaufschlagten Ausgangslenker 9 an den Pendelträger 5 des Streckwerks 1 angeschlossen. Das heißt, die Achse 13 des Ausgangsoberwalzenpaares 4o ist mit ihrem Sattelstück in eine Aufnahme des Ausgangslenkers 9, vorzugsweise durch ein Federelement ge sichert, festgelegt.As can be seen from the figure, the Ausgangsoberwalzenpaar 4o is connected via a spring-loaded
Neben dem Sattelstück der Achse 13 ist mit einer ersten Führungs- und Aufnahmeeinrichtung 29, deren lichter Durchmesser etwas über dem Durchmesser der Achse 13 liegt, ein Käfigelement 25 gelagert, das außer dieser ersten Führungs- und Aufnahmeeinrichtung 29 noch eine zweite Führungs- und Aufnahmeeinrichtung 31 für die Achse 17 des Lieferoberwalzenpaares 11o sowie eine Anschlusseinrichtung 14 zur Abstützung und Justierung des vorzugsweise als Schraubendruckfeder ausgebildeten Druckelements 15 aufweist.
Die Anschlusseinrichtung 14 ist dabei im Bereich oberhalb der zweiten Führungs- und Aufnahmeeinrichtung 31 für die Achse 17 des Lieferoberwalzenpaares 11o angeordnet und weist einen Führungszapfen 16 zur gelenkigen Positionierung des Endes 32 der Schraubendruckfeder 15 auf.
Die Schraubendruckfeder 15 ist außerdem mit ihrem Ende 33 gelenkig an eine Aufnahmeeinrichtung 18 angeschlossen. Die Aufnahmeeinrichtung ist über eine Achse 19 am Pendelträger 5 angeordnet und steht mit dem Pendelträger 5 des Streckwerks 1 in Verbindung.
Das bedeutet, im Montagezustand ist die Schraubendruckfeder 15 durch die Anschlusseinrichtung 14 und die Aufnahmeeinrichtung 18 so ausgerichtet, dass zwischen der Schraubendruckfeder 15 und dem Käfigelement 25 keine Relativbewegungen gegeben sind, die zu Haftreibungen führen könnten.
Der Einsatz einer Schraubendruckfeder 15 als Druckelement führt folglich dazu, dass durch die Schraubendruckfeder 15 eine nahezu hysteresefreie Übertragung einer vorgegebenen Belastungskraft auf das Käfigelement 25 und damit auf das Lieferoberwalzenpaar 11o auch dann gewährleistet ist, wenn das Lieferwalzenunterpaar 11u, was in der Praxis nicht immer zu vermeiden ist, einen etwas unrunden Lauf aufweist.
Das heißt, die durch die Konstruktion vorgegebene Seitenbeweglichkeit einer solchen Schraubendruckfeder 15 gleicht automatisch eventuelle Schwenkbewegungen des Käfigelements 25 aus und ermöglicht eine nahezu haftreibungsfreie Bewegung des Käfigelements 25 um die Achse 13 des Ausgangsoberwalzenpaares 4o.In addition to the saddle piece of the
