- On the stub axle is not rotatably held a suction insert, which in turn is connected via a suction hose to a vacuum source.
- a device for compacting a fiber material is described on a spinning machine, which is intended for retrofitting to a conventional drafting device of a spinning machine.
- the device is arranged downstream of the drafting unit of the spinning machine and serves to compact (compact) a fiber material discharged from the drafting unit.
- the compacted fiber material after passing through a nip, is fed to a swirl-generating device.
- the swirl-generating device consists of z. Example, in a ring spinning machine from a rotor which rotates on a ring, wherein the yarn produced is wound on a rotating sleeve.
- the in the WO 2012068692 A1 described compression device has for use in the usual twin drafting of ring spinning machines on two acted upon by suction, driven and rotating suction drums, which are axially parallel and spaced from each other via a bearing member rotatably mounted on a shaft mounted on a support.
- the carrier has a receptacle for the rotationally fixed mounting of the shaft.
- For axial securing of the suction drums on the shaft is in the WO 2014027234 describes a sleeve-like locking element, which is pushed onto the end portion of the shaft or the shaft journal. This is two suction drums as a unit (module) assigned to a twin drafting system.

- the Inserts are provided with correspondingly shaped suction slots, whereby a corresponding air flow is generated at the periphery of the respective suction drum in a compression region.
- the suction drums are each assigned an annular drive element in the form of a friction wheel, which rests under the action of a compressive load with its circular inner surface partially on the circular peripheral surface of a arranged on the end face of the respective suction drum approach.
- the rotational movement of the driven over the outer circumference friction wheel is transmitted via friction on the peripheral surface of the neck, which is connected to the suction drum.
- the friction wheel in turn is driven by a frictional engagement of the driven lower output roller of the drafting system.
- the friction wheel is held in the axial direction on the approach in its position, forming an axial gap between the closed end face of the suction drum and the friction wheel.
- the invention is therefore the object of an apparatus for compressing a sliver on a spinning machine with a suction drum form such that a simple and fast assembly and disassembly of the suction drum during the entire period of the device is possible.
- the compression device according to the invention can be permanently installed following the respective drafting arrangement of a spinning machine, or be provided for subsequent attachment to a conventional drafting device.
- a bolt is to be understood as meaning a short shaft which has a round cross section.
- the bolt can also be designed as a n-sided profile.
- the suction drum is axially fixed as seen in the axial direction over the bearing element with the bolt and at least one fastening means is provided, via which the bolt is releasably secured in the receptacle.
- axially fixed is to be understood that the bolt is firmly integrated into the assembly consisting of suction drum and bearing element, so that the suction drum and the bolt together form a separate unit of the device.
- a simple separation of the suction drum from the bolt is not possible by the axial fixation of suction drum and bolt.
- the suction drum is removed as the entire unit with the bolt, ie there is no removal of the suction drum from the bolt.
- the main advantage of the axial fixation is that the formation of friction at the junction between the bolt and bearing element is avoided. This has a positive effect on the assembly and disassembly of the suction drum and the maintenance of the spinning machine.
- the at least one fastening means may be integrated in the carrier or constitute a separate component on the carrier. It is possible, for example, that a screw is fastened to the carrier, which secures the bolt in its operating position in the receptacle in the axial direction. It is also possible that the bolt has a radial bore into which a locking pin attached to the carrier projects into the operating position and secures the bolt in the receptacle in the axial direction.

- the fixed connection of suction drum and bolt via a roller bearing without inner ring ie the rolling bearing comprises only one outer ring and rolling elements.
- the suction drum is rotatably connected to the outer ring and is rotatably supported on the rolling elements on the end portion of the bolt.
- the rolling elements for example bearing balls
- the bolt is therefore made of a hardened steel or of ceramic, or has a surface coating.
- the bolt also has on its surface circumferential grooves in which roll the rolling elements.
- the bolt and the rolling bearing form a subassembly of the separate unit. This further simplifies the assembly of the separate unit since the subassembly can be mounted to the suction drum in a single assembly step.
- the fastening means is designed as a locking element, which deflects flexibly in the radial direction Part section is provided and the bolt has a circumferential recess between its two end portions, wherein the flexibly evasive part section protrudes into operating position in the circumferential recess of the bolt and secures the bolt in the axial direction on the carrier.
- Under “depression” is understood to mean a continuous groove extending over the circumference of the bolt.
- the diameter of the bolt decreases toward the recess at an angle between 25 ° to 60 ° with respect to the central axis of the bolt. As a result, a good axial securing of the bolt is ensured in the recording.
- the diameter of the bolt at the end of the bolt tapers at an angle between 25 ° to 60 ° to the central axis of the bolt. This prevents that the bolt runs into the receptacle on the locking element and is blocked when inserted.
- the proposed flexible evasive section When transferring the bolt into the receptacle, the proposed flexible evasive section is displaced by the bolt in the radial direction.
- the reason for this is that the diameter of the bolt is greater than the clear diameter of the receptacle at the location of the flexible evasive section. Due to the radial displacement of the flexibly deflectable portion of the bolt can be easily transferred to its end position (locking position). In the end position, the flexibly deflectable section can again elastically expand into the circumferential recess of the bolt, that is, in the end position, the flexibly deflectable section returns due to its elasticity back to its original radial shape and is securely held in the recess of the bolt.
- the locking element and the recess act together as a kind of snap connection, by means of which the suction drum can be easily mounted or dismounted on the device. At the same time a good axial securing of the suction drum on the support of the device is ensured by means of the snap connection.
- the carrier has a plurality of locking elements which engage in the circumferential recess of the bolt.
- the receptacle is designed as a sleeve, which is arranged rotationally fixed in the carrier and has the flexibly deflectable portion.
- This makes it possible to provide the carrier with a simple bore into which the sleeve is inserted.
- the rotationally fixed arrangement of the sleeve in the carrier takes place, for example, via a type of shaft hub connection, wherein the carrier has an elevation and the sleeve has a depression on its outer circumference into which the elevation projects.
- the flexibly deflectable partial section in the radial direction extends over a part of the circumference of the sleeve and protrudes in its rest position into the cavity of the sleeve, so that at this point the clear diameter of the sleeve is smaller than the diameter of the bolt.
- the sleeve is advantageously made of a plastic which has good elastic properties.
- the flexible evasive part section consists of at least one tongue-shaped portion which extends in the longitudinal direction of the bolt and whose free end protrudes into the circumferential recess of the bolt.
- the inner surface of the tongue-shaped portion whose free end projects into the circumferential recess at least partially in the radial direction at an angle between 10 ° and 25 ° with respect to the central axis of the bolt. This ensures that the tongue-shaped portion during the displacement (assembly) of the bolt can move completely into the region of the recess of the bolt.

- the bolt 36 also has peripheral grooves 47 on its surface, in which unwind the rolling elements 44.
- the carrier 16 for receiving the bolt 36 has a separate sleeve 48.
- the sleeve 48 is non-rotatably arranged in the carrier 16 via a kind of shaft hub connection, wherein the carrier 16 is an increase 52 and the sleeve 48 at its outer periphery a recess 51 (FIG. Figure 5 ), in which the elevation 52 protrudes.

Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Verdichten eines Faserverbandes an einer Spinnmaschine, mit einem Träger, welcher eine Aufnahme für einen Bolzen aufweist, mit einer drehbar gelagerten Saugtrommel, welche eine geschlossene und eine offene Stirnseite aufweist und im Bereich der geschlossenen Stirnseite ein Lagerelement angeordnet ist, über welches die Saugtrommel auf einem Endabschnitt des Bolzens drehbar gelagert ist, wobei der Bolzen aus der offenen Stirnseite der Saugtrommel herausragt.The invention relates to a device for compressing a fiber structure on a spinning machine, comprising a support, which has a receptacle for a bolt, with a rotatably mounted suction drum, which has a closed and an open end side and arranged in the region of the closed end side of a bearing element is, via which the suction drum is rotatably mounted on an end portion of the bolt, wherein the bolt protrudes from the open end side of the suction drum.
Bei einer Vorrichtung zum Verdichten eines Faserverbandes in einer Spinnmaschine gemäß der
In der
Die in der
Den Saugtrommeln ist jeweils ein ringförmiges Antriebselement in Form eines Reibrades zugeordnet, das unter Einwirkung einer Druckbelastung mit seiner kreisförmigen Innenfläche teilweise auf der kreisförmigen Umfangsfläche eines an der Stirnseite der jeweiligen Saugtrommel angeordneten Ansatzes aufliegt. Dabei wird die Drehbewegung des über den Aussenumfang angetriebenen Reibrades über Friktion auf die Umfangsfläche des Ansatzes übertragen, welcher mit der Saugtrommel verbunden ist. Das Reibrad wiederum wird über einen Reibschluss von der angetriebenen unteren Ausgangswalze des Streckwerks angetrieben. Durch eine am Ende des Ansatzes befestigte Abschlusskappe wird das Reibrad in axialer Richtung auf dem Ansatz in seiner Position gehalten, wobei sich zwischen der geschlossenen Stirnseite der Saugtrommel und dem Reibrad ein axialer Spalt ausbildet.The suction drums are each assigned an annular drive element in the form of a friction wheel, which rests under the action of a compressive load with its circular inner surface partially on the circular peripheral surface of a arranged on the end face of the respective suction drum approach. The rotational movement of the driven over the outer circumference friction wheel is transmitted via friction on the peripheral surface of the neck, which is connected to the suction drum. The friction wheel in turn is driven by a frictional engagement of the driven lower output roller of the drafting system. By attached to the end of the approach end cap, the friction wheel is held in the axial direction on the approach in its position, forming an axial gap between the closed end face of the suction drum and the friction wheel.
Während des Verdichtungsvorgangs können sich einzelne Fasern vom zu verdichtenden Fasergut lösen und im Innenraum der Saugtrommel ablagern. Dies kann zu einer Verstopfung des Saugschlitzes führen, wodurch die Verdichtung des Faserbandes nicht mehr sichergestellt ist. Zudem können sich Fasern am Umfang der Saugtrommel ablagern und durch Luftströmungen in den axialen Spalt zwischen der geschlossenen Stirnseite der Saugtrommel und dem Reibrad gelangen. Hierbei besteht die Gefahr, dass Fasern, die in den axialen Spalt gelangen, sich bis an den Aussenumfang des Ansatzes fortbewegen und an diesem festsetzen. Dies hat zur Folge, dass die Innenfläche des Reibrades nicht mehr in direktem Kontakt mit dem Aussenumfang des Ansatzes steht, so dass eine kontinuierliche Übertragung des Antriebsmoments vom Reibrad auf die Saugtrommel nicht mehr gewährleistet ist. Als Folge ändert sich das Geschwindigkeitsverhältnis zwischen der Saugtrommel und der unteren Ausgangswalze des Streckwerks. Hierdurch wird das zu verdichtende Fasergut im Verdichtungsbereich gestaucht, was sich negativ auf die Qualität der Verdichtung des Fasergutes auswirkt.During the compression process, individual fibers can be released from the fiber material to be compacted and deposited in the interior of the suction drum. This can lead to a blockage of the suction slot, whereby the compression of the sliver is no longer ensured. In addition, fibers can be deposited on the circumference of the suction drum and pass through air flows in the axial gap between the closed end face of the suction drum and the friction wheel. In this case, there is a risk that fibers that reach the axial gap, move to the outer periphery of the approach and attach to this. This has the consequence that the inner surface of the friction wheel is no longer in direct contact with the outer circumference of the neck, so that a continuous transmission of the drive torque from the friction wheel on the suction drum is no longer guaranteed. As a result, the speed ratio between the suction drum and the lower output roller of the drafting system changes. As a result, the fiber material to be compressed is compressed in the compression region, which has a negative effect on the quality of the compaction of the fiber material.
Aufgrund der beschriebenen Problematik, besteht daher die Notwendigkeit, die Saugtrommel nach einer bestimmten Laufzeit der Verdichtungsvorrichtung vom Träger zu entfernen und die Saugtrommel von den angesammelten Fasern zu befreien. Dabei wird die Saugtrommel vom Bedienpersonal gemeinsam mit dem eingepressten Lagerelement vom Wellenzapfen abgezogen, ausserhalb der Vorrichtung gereinigt und wieder auf den Wellenzapfen aufgesteckt. Ein wesentlicher Nachteil besteht darin, dass sich nach häufiger Montage bzw. Demontage der Saugtrommel Reibungsrost an der Aussenfläche des Wellenzapfens und der Innenfläche des Lagerelements bildet. Eine einfache und schnelle Montage bzw. Demontage der Saugtrommel ist dadurch mit zunehmender Laufzeit der Vorrichtung nicht mehr sichergestellt. Dies wirkt sich negativ auf den Wartungsaufwand der Spinnmaschine aus.Due to the problem described, there is therefore a need to remove the suction drum after a certain period of the compacting device from the carrier and to free the suction drum of the accumulated fibers. The suction drum is deducted by the operator together with the pressed-bearing element from the shaft journal, cleaned outside the device and plugged back onto the shaft journal. A major disadvantage is that after frequent assembly or disassembly of the suction drum frictional grating forms on the outer surface of the shaft journal and the inner surface of the bearing element. A simple and quick assembly or disassembly of the suction drum is thus no longer ensured with increasing running time of the device. This has a negative effect on the maintenance of the spinning machine.
Der Erfindung liegt somit die Aufgabe zugrunde eine Vorrichtung zum Verdichten eines Faserbandes an einer Spinnmaschine mit einer Saugtrommel derart auszubilden, dass eine einfache und schnelle Montage bzw. Demontage der Saugtrommel während der gesamten Laufzeit der Vorrichtung möglich ist.The invention is therefore the object of an apparatus for compressing a sliver on a spinning machine with a suction drum form such that a simple and fast assembly and disassembly of the suction drum during the entire period of the device is possible.

Im Rahmen der Erfindung ist unter einem Bolzen eine kurze Welle zu verstehen, welche einen runden Querschnitt aufweist. Der Bolzen kann jedoch auch als ein n-eckiges Profil ausgebildet sein.The compression device according to the invention can be permanently installed following the respective drafting arrangement of a spinning machine, or be provided for subsequent attachment to a conventional drafting device. In the context of the invention, a bolt is to be understood as meaning a short shaft which has a round cross section. However, the bolt can also be designed as a n-sided profile.
Die Aufgabe wird dadurch gelöst, dass die Saugtrommel in ihrer axialen Richtung gesehen über das Lagerelement mit dem Bolzen axial fixiert ist und wenigstens ein Befestigungsmittel vorgesehen ist, über welches der Bolzen in der Aufnahme lösbar befestigt ist. Unter "axial fixiert" ist dabei zu verstehen, dass der Bolzen in die Baugruppe bestehend aus Saugtrommel und Lagerelement fest integriert ist, so dass die Saugtrommel und der Bolzen gemeinsam eine separate Einheit der Vorrichtung bilden. Im Unterschied zum Stand der Technik ist durch die axiale Fixierung von Saugtrommel und Bolzen ein einfaches Trennen der Saugtrommel vom Bolzen nicht möglich. Die Saugtrommel wird als gesamte Baueinheit mit dem Bolzen entfernt, d.h es erfolgt kein Abziehen der Saugtrommel vom Bolzen. Der wesentliche Vorteil der axialen Fixierung besteht darin, dass die Bildung von Reibrost an der Verbindungsstelle zwischen Bolzen und Lagerelement vermieden wird. Dies wirkt sich positiv auf die Montage bzw. Demontage der Saugtrommel und den Wartungsaufwand der Spinnmaschine aus. Das wenigstens eine Befestigungsmittel kann in den Träger integriert sein oder ein separates Bauteil am Träger darstellen. Es ist z.B möglich, dass am Träger eine Schraube befestigt ist, welche den Bolzen in seiner Betriebsstellung in der Aufnahme in axialer Richtung sichert. Auch ist es möglich, dass der Bolzen eine radiale Bohrung aufweist, in welche ein am Träger befestigter Sicherungsstift in Betriebsstellung hineinragt und den Bolzen in der Aufnahme in axialer Richtung sichert. Als vorteilhaft hat es sich erwiesen, wenn die fixe Verbindung von Saugtrommel und Bolzen über ein Wälzlager erfolgt, welches einen Aussenring, einen Innenring und Wälzkörper umfasst. Die Saugtrommel ist dabei an ihrer geschlossenen Stirnseite mit dem Aussenring und der Endabschnitt des Bolzens mit dem Innenring des Wälzlagers z.B über eine Presspassung drehfest verbunden. Über die Wälzkörper ist die Saugtrommel auf dem Bolzen drehbar gelagert. Diese Art der fixen Verbindung hat den Vorteil eines einfachen Zusammenbaus der separaten Einheit. Auch besteht die Möglichkeit, dass die fixe Verbindung von Saugtrommel und Bolzen über ein Wälzlager ohne Innenring erfolgt, d.h das Wälzlager lediglich einen Aussenring und Wälzkörper umfasst. Die Saugtrommel ist dabei mit dem Aussenring drehfest verbunden und stützt sich über die Wälzkörper drehbar auf dem Endabschnitt des Bolzens ab. Im Unterschied zu einem Wälzlager mit Innenring stehen dabei die Wälzkörper z.B Lagerkugeln in direktem Kontakt mit der Oberfläche des Bolzens. Vorteilhafterweise ist der Bolzen daher aus einem gehärteten Stahl oder aus Keramik hergestellt, oder weist eine Oberflächenbeschichtung auf. Damit ein guter Lauf der Wälzkörper sichergestellt ist, weist der Bolzen zudem an seiner Oberfläche umlaufende Rillen auf, in welchen die Wälzkörper abrollen. Bei dieser Art der fixen Verbindung bilden der Bolzen und das Wälzlager eine Unterbaugruppe der separaten Einheit. Hierdurch wird der Zusammenbau der separaten Einheit weiter vereinfacht, da die Unterbaugruppe in einem einzigen Montageschritt an die Saugtrommel montiert werden kann.The object is achieved in that the suction drum is axially fixed as seen in the axial direction over the bearing element with the bolt and at least one fastening means is provided, via which the bolt is releasably secured in the receptacle. By "axially fixed" is to be understood that the bolt is firmly integrated into the assembly consisting of suction drum and bearing element, so that the suction drum and the bolt together form a separate unit of the device. In contrast to the prior art, a simple separation of the suction drum from the bolt is not possible by the axial fixation of suction drum and bolt. The suction drum is removed as the entire unit with the bolt, ie there is no removal of the suction drum from the bolt. The main advantage of the axial fixation is that the formation of friction at the junction between the bolt and bearing element is avoided. This has a positive effect on the assembly and disassembly of the suction drum and the maintenance of the spinning machine. The at least one fastening means may be integrated in the carrier or constitute a separate component on the carrier. It is possible, for example, that a screw is fastened to the carrier, which secures the bolt in its operating position in the receptacle in the axial direction. It is also possible that the bolt has a radial bore into which a locking pin attached to the carrier projects into the operating position and secures the bolt in the receptacle in the axial direction. It has proven to be advantageous if the fixed connection of suction drum and bolt via a roller bearing, which comprises an outer ring, an inner ring and rolling elements. The suction drum is rotatably connected at its closed end face to the outer ring and the end portion of the bolt with the inner ring of the bearing, for example via a press fit. About the rolling elements, the suction drum is rotatably mounted on the bolt. This type of fixed connection has the advantage of easy assembly of the separate unit. There is also the possibility that the fixed connection of suction drum and bolt via a roller bearing without inner ring, ie the rolling bearing comprises only one outer ring and rolling elements. The suction drum is rotatably connected to the outer ring and is rotatably supported on the rolling elements on the end portion of the bolt. In contrast to a rolling bearing with an inner ring, the rolling elements, for example bearing balls, are in direct contact with the surface of the bolt. Advantageously, the bolt is therefore made of a hardened steel or of ceramic, or has a surface coating. Thus, a good running of the rolling elements is ensured, the bolt also has on its surface circumferential grooves in which roll the rolling elements. In this type of fixed connection, the bolt and the rolling bearing form a subassembly of the separate unit. This further simplifies the assembly of the separate unit since the subassembly can be mounted to the suction drum in a single assembly step.
Als vorteilhaft hat es sich hierbei erwiesen, wenn das Befestigungsmittel als ein Verriegelungselement ausgeführt ist, das mit einem in radialer Richtung flexibel ausweichbaren Teilabschnitt versehen ist und der Bolzen zwischen seinen beiden Endabschnitten eine umlaufende Vertiefung aufweist, wobei der flexibel ausweichbare Teilabschnitt in Betriebsstellung in die umlaufende Vertiefung des Bolzens hineinragt und den Bolzen in axialer Richtung am Träger sichert. Unter "Vertiefung" ist eine über den Umfang des Bolzens durchgehend verlaufende Nut zu verstehen. Vorteilhafterweise nimmt der Durchmesser des Bolzens zur Vertiefung hin unter einem Winkel zwischen 25° bis 60° in Bezug zur Mittelachse des Bolzens ab. Hierdurch ist eine gute axiale Sicherung des Bolzens in der Aufnahme sichergestellt. Damit bei der Montage der Bolzen sicher über das Verriegelungselement in seine Endposition verschoben werden kann, ist es weiter vorteilhaft, wenn sich der Durchmesser des Bolzens am Ende des Bolzens unter einem Winkel zwischen 25° bis 60° zur Mittelachse des Bolzens verjüngt. Damit wird verhindert, dass der Bolzen beim Einführen in die Aufnahme am Verriegelungselement aufläuft und blockiert wird.It has proved to be advantageous in this case if the fastening means is designed as a locking element, which deflects flexibly in the radial direction Part section is provided and the bolt has a circumferential recess between its two end portions, wherein the flexibly evasive part section protrudes into operating position in the circumferential recess of the bolt and secures the bolt in the axial direction on the carrier. Under "depression" is understood to mean a continuous groove extending over the circumference of the bolt. Advantageously, the diameter of the bolt decreases toward the recess at an angle between 25 ° to 60 ° with respect to the central axis of the bolt. As a result, a good axial securing of the bolt is ensured in the recording. Thus, during assembly of the bolt can be safely moved over the locking element in its final position, it is also advantageous if the diameter of the bolt at the end of the bolt tapers at an angle between 25 ° to 60 ° to the central axis of the bolt. This prevents that the bolt runs into the receptacle on the locking element and is blocked when inserted.
Bei der Überführung des Bolzens in die Aufnahme wird der vorgeschlagene flexibel ausweichbare Teilabschnitt durch den Bolzen in radialer Richtung verdrängt. Grund hierfür ist, dass der Durchmesser des Bolzens grösser ist als der lichte Durchmesser der Aufnahme an der Stelle des flexibel ausweichbaren Teilabschnitts. Durch das radiale Verdrängen des flexibel ausweichbaren Teilabschnitts kann der Bolzen problemlos in seine Endstellung (Verriegelungsstellung) überführt werden. In der Endstellung kann sich der flexibel ausweichbare Teilabschnitt in die umlaufende Vertiefung des Bolzens wieder elastisch ausweiten, d.h in der Endstellung kehrt der flexibel ausweichbare Teilabschnitt aufgrund seiner Elastizität wieder in seine ursprüngliche radiale Form zurück und wird sicher in der Vertiefung des Bolzens gehalten.When transferring the bolt into the receptacle, the proposed flexible evasive section is displaced by the bolt in the radial direction. The reason for this is that the diameter of the bolt is greater than the clear diameter of the receptacle at the location of the flexible evasive section. Due to the radial displacement of the flexibly deflectable portion of the bolt can be easily transferred to its end position (locking position). In the end position, the flexibly deflectable section can again elastically expand into the circumferential recess of the bolt, that is, in the end position, the flexibly deflectable section returns due to its elasticity back to its original radial shape and is securely held in the recess of the bolt.
Das Verriegelungselement und die Vertiefung wirken wie eine Art Schnappverbindung zusammen, mittels welcher die Saugtrommel einfach an der Vorrichtung montiert bzw. demontiert werden kann. Gleichzeitig ist mittels der Schnappverbindung eine gute axiale Sicherung der Saugtrommel am Träger der Vorrichtung sichergestellt. Um die axiale Sicherung des Bolzens weiter zu verstärken, ist es zudem möglich, dass der Träger mehrere Verriegelungselemente aufweist, welche in die umlaufende Vertiefung des Bolzens eingreifen.The locking element and the recess act together as a kind of snap connection, by means of which the suction drum can be easily mounted or dismounted on the device. At the same time a good axial securing of the suction drum on the support of the device is ensured by means of the snap connection. To further enhance the axial securing of the bolt, it is also possible that the carrier has a plurality of locking elements which engage in the circumferential recess of the bolt.
Weiter ist es von Vorteil, wenn die Aufnahme als eine Hülse ausgeführt ist, welche drehfest im Träger angeordnet ist und den flexibel ausweichbaren Teilabschnitt aufweist. Hierdurch ist es möglich den Träger mit einer einfachen Bohrung zu versehen, in welche die Hülse eingesetzt wird. Die drehfeste Anordnung der Hülse im Träger erfolgt z.B über eine Art Welle Nabe Verbindung, wobei der Träger eine Erhöhung und die Hülse an ihrem äusseren Umfang eine Vertiefung aufweist, in welche die Erhöhung hineinragt. Der in radialer Richtung flexibel ausweichbare Teilabschnitt erstreckt sich über einen Teil des Umfangs der Hülse und ragt in seiner Ruhelage in den Hohlraum der Hülse hinein, so dass an dieser Stelle der lichte Durchmesser der Hülse geringer ist als der Durchmesser des Bolzens. Die Hülse ist vorteilhafterweise aus einem Kunststoff hergestellt, welcher gute elastische Eigenschaften aufweist.Further, it is advantageous if the receptacle is designed as a sleeve, which is arranged rotationally fixed in the carrier and has the flexibly deflectable portion. This makes it possible to provide the carrier with a simple bore into which the sleeve is inserted. The rotationally fixed arrangement of the sleeve in the carrier takes place, for example, via a type of shaft hub connection, wherein the carrier has an elevation and the sleeve has a depression on its outer circumference into which the elevation projects. The flexibly deflectable partial section in the radial direction extends over a part of the circumference of the sleeve and protrudes in its rest position into the cavity of the sleeve, so that at this point the clear diameter of the sleeve is smaller than the diameter of the bolt. The sleeve is advantageously made of a plastic which has good elastic properties.
Als vorteilhaft hat es sich zudem erwiesen, wenn der flexibel ausweichbare Teilabschnitt aus mindestens einem zungenförmigen Abschnitt besteht, welcher sich in Längsrichtung des Bolzens erstreckt und dessen freies Ende in die umlaufende Vertiefung des Bolzens hineinragt. Durch den wenigstens einen flexiblen zungenförmigen Abschnitt, der in die Vertiefung des Bolzens in der beschriebenen Endstellung in radialer Richtung hineinragt, wird eine axiale Sicherung des Bolzens mit der drehbar gelagerten Saugtrommel am Träger der Vorrichtung gewährleistet. Hierbei ist es von Vorteil, wenn das freie Ende des zungenförmigen Abschnitts in Richtung der Saugtrommel zeigt. Damit wird eine einfache und schnelle Überführung des Bolzens ohne grossen Kraftaufwand in seine Endposition ermöglicht.It has also proven to be advantageous if the flexible evasive part section consists of at least one tongue-shaped portion which extends in the longitudinal direction of the bolt and whose free end protrudes into the circumferential recess of the bolt. By the at least one flexible tongue-shaped portion which projects into the recess of the bolt in the described end position in the radial direction, an axial securing of the bolt is ensured with the rotatably mounted suction drum on the support of the device. It is advantageous if the free end of the tongue-shaped portion points in the direction of the suction drum. This allows a simple and quick transfer of the bolt without much effort in its final position.
Schliesslich ist es von Vorteil, wenn die Innenfläche des zungenförmigen Abschnitts, dessen freies Ende in die umlaufende Vertiefung wenigstens teilweise in radialer Richtung hineinragt unter einem Winkel zwischen 10° und 25° in Bezug zur Mittelachse des Bolzens verläuft. Damit wird gewährleistet, dass sich der zungenförmige Abschnitt bei der Verschiebung (Montage) des Bolzens vollständig in den Bereich der Vertiefung des Bolzens bewegen kann.Finally, it is advantageous if the inner surface of the tongue-shaped portion whose free end projects into the circumferential recess at least partially in the radial direction at an angle between 10 ° and 25 ° with respect to the central axis of the bolt. This ensures that the tongue-shaped portion during the displacement (assembly) of the bolt can move completely into the region of the recess of the bolt.

Wie aus
Im Anschluss an die Streckwerkseinheit 2 weisst die Spinnmaschine eine schwenkbar gelagerte Verdichtungsvorrichtung VM zum Verdichten eines von der Streckwerkseinheit 2 abgegebenen Faserverbandes (Faserguts) V auf. Die Verdichtungsvorrichtung VM ist dabei nachträglich an die Streckwerkseinrichtung 2 angebaut. Die Verdichtungsvorrichtung VM weist zwei mit Saugluft beaufschlagte, angetriebene und umlaufende Saugtrommeln 14 auf, welche achsparallel und im Abstand zueinander auf einem Träger 16 drehbar gelagert sind. Der Träger 16 weist einen an eine Unterdruckquelle SP angeschlossenen Saugkanal SK auf, der mit dem Innenraum der Saugtrommeln 14 über entsprechende Einsätze 15 verbunden ist. Die Verdichtungsvorrichtung VM ist in der
Das von dem Ausgangswalzenpaar 7, 8 abgegebene verstreckte Fasergut V wird nach unten abgelenkt und gelangt in den Bereich einer Saugzone SZ einer nachfolgenden Saugtrommel 14. Die jeweilige Saugtrommel 14 ist mit auf ihrem Umfang verlaufenden Perforationen, bzw. Öffnungen Ö versehen. Innerhalb der drehbar gelagerten Saugtrommel 14 ist jeweils ein stationär gelagerter Saugeinsatz 15 angeordnet. Wie schematisch aus
Innerhalb des Trägers 16 verläuft ein Saugkanal SK, der eine Öffnung S2 auf der Innenfläche des Endstückes des Trägers 16 aufweist und eine weitere Öffnung S1, welche im Bereich der Aufnahme 19 angeordnet ist und mit dem Innenraum 29 des jeweiligen Saugeinsatzes 15 in Verbindung steht. Die Öffnung S2 steht in der Arbeitsposition einer Öffnung SR eines Saugrohres 41 gegenüber, wodurch der Innenraum des Saugrohres 41 mit dem Saugkanal SK verbunden ist. Wie aus
Die Welle 17 ist in einer Aufnahme 19 des Trägers 16 befestigt. Die Welle 17 weist im Bereich der Aufnahme 19 einen etwas grösseren Durchmesser auf, während die, von dieser Aufnahme nach beiden Seiten sich erstreckenden Enden der Welle 17 einen verjüngten Durchmesser aufweisen und zur Aufnahme der jeweiligen Lager K dienen. Die jeweilige Saugtrommel 14 weist an ihrer geschlossenen Stirnseite 35, d.h an dem vom Träger 16 wegzeigenden Ende, jeweils einen ringförmigen Ansatz 13 auf. Auf einem Teilbereich des Aussenumfanges AU des Ansatzes 13 liegt ein Teilbereich der Innenfläche IF eines ringförmigen Antriebelements 20 auf. Das Antriebselement 20 ist als ein Reibrad ausgeführt.The

Im Anschluss an die Saugzone SZ ist für jede der Saugtrommeln 14 eine Klemmwalze 23 vorgesehen, die über eine Druckbelastung auf der jeweiligen Saugtrommel 14 aufliegt und mit dieser eine Klemmlinie P bildet. Dabei ist die jeweilige Klemmwalze 23 auf einer Achse 22 drehbar gelagert, welche an einem Lagerelement 25 befestigt ist, das über Schrauben 27 mit einem Federelement 26 verbunden ist. Das Federelement 26, über welches eine Anpresskraft der Klemmwalze 23 in Richtung der Saugtrommel 14 erzeugt wird, ist über die schematisch dargestellten Schrauben 27 am Träger 16 befestigt. Die Klemmlinie P bildet gleichzeitig einen so genannten "Drehsperrungsspalt", von welchem das Fasergut in der Förderrichtung FS in Form eines komprimierten Garnes FK unter Drehungserteilung einer schematisch gezeigten Ringspinneinrichtung 1 zugeführt wird.Subsequent to the suction zone SZ a
Um bei einem Fadenbruch zwischen der Klemmlinie P und der Spule 33 das weiterhin über den Klemmpunkt P gelieferte Garn FK absaugen zu können, ist beidseitig des Trägers 16 jeweils ein Absaugrohr 30 befestigt, deren jeweilige Öffnung 31, welche dem Träger 16 zugewandt ist, mit dem Kanal SK verbunden ist. D. h. bei einem auftretenden Fadenbruch wird das Ende des weiterhin gelieferten Fadens, bzw. Garnes, über das jeweilige Absaugrohr 30 unter der Einwirkung des über die Unterdruckquelle SP erzeugten Unterdrucks über den Saugkanal SK dem Absaugrohr 30 zugeführt, welcher diesen über den oder die Kanäle 42 zur weiteren Abführung an eine Sammelstelle an den Hauptkanal 43 abgibt.In order to be able to extract the yarn FK delivered further via the clamping point P in the event of a yarn break between the nip line P and the
Während des Verdichtungsvorgangs können sich einzelne Fasern vom zu verdichtenden Fasergut V lösen und im Innenraum 28 der Saugtrommel 14 ablagern. Dies kann zu einer Verstopfung des Saugschlitzes S führen, wodurch die Verdichtung des Faserguts V nicht mehr sichergestellt ist. Zudem können sich Fasern am Umfang der Saugtrommel 14 ablagern und durch Luftströmungen in den axialen Spalt zwischen der geschlossenen Stirnseite 34 der Saugtrommel 14 und dem Reibrad 20 gelangen. Hierbei besteht die Gefahr, dass Fasern, die in den axialen Spalt gelangen, sich bis an den Aussenumfang AU des Ansatzes 13 fortbewegen und an diesem festsetzen. Dies hat zur Folge, dass die Innenfläche IF des Reibrades 20 nicht mehr in direktem Kontakt mit dem Aussenumfang AU des Ansatzes 13 steht, so dass eine kontinuierliche Übertragung des Antriebsmoments vom Reibrad 20 auf die Saugtrommel 14 nicht mehr gewährleistet ist. Als Folge ändert sich das Geschwindigkeitsverhältnis zwischen der Saugtrommel 14 und der unteren Ausgangswalze 7 des Streckwerks. Hierdurch wird das zu verdichtende Fasergut V im Verdichtungsbereich gestaucht, was sich negativ auf die Qualität der Verdichtung des Fasergutes V auswirkt.During the compression process, individual fibers can be released from the fiber material V to be compacted and deposited in the
Aufgrund der beschriebenen Problematik, besteht daher die Notwendigkeit, die Saugtrommel 14 nach einer bestimmten Laufzeit der Verdichtungsvorrichtung VM vom Träger 16 zu entfernen und die Saugtrommel 14 von den angesammelten Fasern zu befreien. Dabei wird die Saugtrommel 14 vom Bedienpersonal gemeinsam mit dem eingepressten Lagerelement K von der Welle 17 abgezogen, ausserhalb der Vorrichtung VM gereinigt und wieder auf die Welle 17 aufgesteckt. Ein wesentlicher Nachteil besteht darin, dass sich nach häufiger Montage bzw. Demontage der Saugtrommel 14 Reibungsrost an der Aussenfläche der Wellen 17 und der Innenfläche des Lagerelements K bildet. Eine einfache und schnelle Montage bzw. Demontage der Saugtrommel 14 ist dadurch mit zunehmender Laufzeit der Vorrichtung VM nicht mehr sichergestellt. Dies wirkt sich negativ auf den Wartungsaufwand der Spinnmaschine aus.Due to the problem described, there is therefore a need to remove the

Im Innenraum 28 der Saugtrommel 14 ist ein Saugeinsatz 15 angeordnet, welcher auf einem Teilbereich seines Umfanges einen Saugschlitz S aufweist. Der Saugeinsatz 15 ist im Ausführungsbeispiel in den Träger 16 integriert. Zur Aufnahme des Bolzens 36 weist der Träger 16 eine Aufnahme 19 auf. Damit der Bolzen 36 einfach in die Aufnahme 19 einführbar ist, weist der Bolzen 36 an seinem aus der Saugtrommel (14) herausragenden Ende eine Verjüngung seines Durchmessers DB auf. Im Ausführungsbeispiel nach
Im Bereich des ringförmigen Ansatzes 13 der Saugtrommel 14 ist eine Abschlusskappe 21 befestigt, welche mit ihrem Aussendurchmesser die lichte Weite des Reibrades 20 überragt. Die Abschlusskappe 21 ist dabei mit einem ringförmigen Ansatz 40 versehen, der in die lichte Weite des ringförmigen Ansatzes 13 der Saugtrommel 14 hineinragt. Der ringförmige Aufsatz 40 ist mit zusätzlichen nach aussen ragenden Nocken versehen, welche zur Fixierung der Abschlusskappe 21 in umlaufende Vertiefungen innerhalb der lichten Weite des Ansatzes 13 eingreifen.In the region of the

Bei der Überführung des Bolzens 36 in die Hülse 48 wird der zungenförmigen Abschnitt 50 durch den Bolzen 36 in radialer Richtung verdrängt. Grund hierfür ist, dass der Durchmesser DB des Bolzens 36 grösser ist als der lichte Durchmesser LD der Hülse 48 (
Der Durchmesser DB des Bolzens 36 nimmt zur Vertiefung 53 hin unter einem Winkel a zwischen 25° bis 60° in Bezug zur Mittelachse A1 des Bolzens 36 ab. Hierdurch ist eine gute axiale Sicherung des Bolzens 36 in der Hülse 48 sichergestellt. Damit bei der Montage der Bolzen 36 sicher über den zungenförmigen Abschnitt 50 in seine Endposition verschoben werden kann, verjüngt sich der Durchmesser DB des Bolzens 36 an dem aus der Saugtrommel 14 herausragenden Ende unter einem Winkel b zwischen 25° bis 60° in Bezug zur Mittelachse A1 des Bolzens 36. Damit wird verhindert, dass der Bolzen 36 beim Einführen in die Hülse 48 am zungenförmigen Abschnitt 50 aufläuft und blockiert wird.The diameter DB of the
