Definitions
- the present invention relates to an opening roller housing for an opening roller of an open-end spinning device with a feed opening for feeding a fiber material into the opening roller housing, with a discharge opening for removing dissolved individual fibers from the opening roller housing, with a dirt separation opening for separating impurities from the fiber material and with a the opening roller surrounding inner peripheral wall during operation with a fiber-guiding area, which extends from the feed opening via the dirt separation opening to the discharge opening, wherein the opening roller housing comprises a hollow cylindrical ring.
- Opening roller housings have become known in various designs in the prior art and are used on open-end spinning devices in order to open up a ribbon-shaped fiber material fed to the opening device into individual fibers and then to feed the opened up individual fibers to the spinning device.
- an opening roller housing is known that is produced as a cast part, for example in an injection molding process or die casting process.
- the housing thus consists of a relatively soft material.
- An insert is therefore provided in the interior of the housing to protect the wall surfaces of the housing and to improve the separation of dirt.
- This consists of thin sheet metal and is pot-shaped so that it also forms a rear wall of the opening roller housing.
- the insert has almost no edges on which fibers could get stuck, so that the risk of the opening roller housing flying is reduced.
- the insert is also easily replaceable.
- an opening roller housing with an exchangeable insert is known.
- the insert is arranged there in the area after the feed opening and extends into the area of the dirt separation opening.
- the insert forms at least partially, but at least in the area of the dirt separation opening, the surrounding peripheral wall of the opening roller housing.
- the opening roller housing can be easily adapted to different fiber materials and vibration conditions.
- the size and also the position of the dirt separation opening can be changed as a result.
- various inserts must be kept ready and assembled.
- an opening roller housing with an exchangeable insert is also known.
- the insert is designed as a hollow-cylindrical ring, which has a trough-shaped fiber inlet into the discharge opening and a wall area with an opening for setting the dirt-separating opening.
- the annular gap between the opening roller housing and the opening roller should be able to be adjusted by the thickness of its cylinder wall.
- the object of the present invention is therefore to propose an opening roller housing which is easy to manufacture and assemble and which also avoids warping of the opening roller housing.
- An opening roller housing for an opening roller of an open-end spinning device has a feed opening for feeding a fiber material into it opening roller housing, a discharge opening for removing dissolved individual fibers from the opening roller housing, a dirt separation opening for separating impurities from the fiber material and an inner peripheral wall surrounding the opening roller during operation with a fiber-guiding area which extends from the feed opening via the dirt separation opening to the discharge opening.
- the opening roller housing comprises a hollow-cylindrical ring.
- the hollow-cylindrical ring is designed as a self-supporting component which can be attached directly to a support part of the open-end spinning device and which contains both the inner peripheral wall with the fiber-guiding area and the feed opening, the discharge opening and the dirt separation opening.
- the proposed opening roller housing therefore no longer has an additional insert.
- the ring-shaped opening roller housing forms the main body of the opening roller housing and can be fastened directly to the carrier part, this can be done quickly and easily.
- the ring-shaped opening roller housing is reduced to the essential functions, namely the provision of the openings mentioned and the fiber-guiding area, and has a very compact shape, the opening roller housing can nevertheless be manufactured inexpensively. Since the ring-shaped opening roller housing is designed in one piece, there are also no gaps to which fibers could adhere. The tendency of the opening roller housing to fly is thus reduced.
- the ring has fastening bores, in particular threads, for fastening it to the carrier part of the open-end spinning device.
- the ring has fastening bores, in particular threads, for fastening it to the carrier part of the open-end spinning device.
- the opening roller housing can hereby be attached to the carrier in a simple manner by screwing. High driving forces can be generated by screwing, so that the opening roller housing can be fastened to the carrier part with almost no gaps. This further reduces the tendency to fly away.
- the mounting holes can be designed as through holes, so that the opening roller housing can be mounted from the front of the spinning device.
- the fastening bores are designed as blind bores and, in particular, as threads.
- the fastening can take place from a rear side of the carrier part of the open-end spinning device. This is advantageous, for example, when the carrier part is a pivoting housing that can be folded away from the open-end spinning device.
- fastening bores are arranged on an end face of the ring.
- the shape of the ring can still be kept very compact, since no additional fastening straps are required.
- the gap-free attachment of the opening roller housing to the carrier part can be supported even further as a result.
- the opening roller housing also includes a plastic cover surrounding the ring.
- the plastic cover creates a visually appealing transition to the carrier part of the open-end spinning device.
- the plastic cover can be used to integrate and/or cover other components such as a fiber duct insert.
- fastening bores are arranged on an end face of the ring.
- the shape of the ring can still be kept very compact, since no additional fastening straps are required.
- the gap-free attachment of the opening roller housing to the carrier part can be supported even further as a result.
- the opening roller housing also includes a plastic cover surrounding the ring.
- the plastic cover creates a visually appealing transition to the carrier part of the open-end spinning device.
- the plastic cover can be used to integrate and/or cover other components such as a fiber duct insert.
- the plastic cover is integrally connected to the ring, in particular is injection molded directly onto the hollow-cylindrical ring.
- the opening roller housing is made in one piece even when using different materials for the hollow cylindrical ring and the plastic cover.
- the opening roller housing is closed off with no gaps by the plastic cover, further reducing the risk of fibers sticking to gaps.
- the integral connection can be made in particular by direct injection molding of the plastic cover onto the hollow-cylindrical ring.
- weld the two parts together for example by ultrasonic welding. Bonding is also still an option.
- the ring has one or more form-fitting elements for form-fitting connection to the plastic cover, with the form-fitting element or elements preferably being/are arranged on an outer peripheral wall of the ring.
- Such positive-locking elements can also be advantageous in the case of a material-to-material connection as described above.
- an additional Form fit between the hollow cylindrical ring and the plastic cover made.
- the plastic cover is particularly well fixed to the hollow-cylindrical ring. If the form-fitting elements are attached to the outer peripheral wall of the ring, then they are outside of functional surfaces or functional areas.
- the plastic cover has one or more clip elements for connection to the ring.
- the plastic cover is detachably connected to the ring.
- the clip elements snap into a snap-in shoulder of the ring that is shaped to correspond to the clip elements.
- this design can offer advantages.
- the hollow-cylindrical ring forms the base body of the opening roller housing, which carries the plastic cover. The advantages of simple attachment are thus also achieved with this design.
- the ring consists of a metallic material, in particular a steel or aluminum material, and is preferably designed as a cast part.
- the hollow-cylindrical ring can be made stable and wear-resistant and can therefore also directly form the fiber-guiding surfaces of the opening roller housing. Due to the design as a cast part, shapes that are not completely round, shapes with extensions and the integration of other functions are also possible.
- the hollow-cylindrical ring is machined.
- a ring designed as a cast part can also be easily and precisely be reworked in an exciting way.
- the fiber-guiding surfaces and optionally air-guiding surfaces can be produced with a high surface quality and great accuracy.
- the inner peripheral wall of the ring is provided with a coating, in particular an anti-wear coating, at least in the fiber-guiding area. This can improve the service life of the opening roller housing. Furthermore, a coating can also be used to improve the surface quality as well as the flow properties and fiber guidance properties of the ring.
- the ring also contains a bypass opening for supplying an inlet air flow into the opening roller housing.
- the bypass opening is used to supply additional air to the opening roller housing so that less air has to be sucked in through the dirt separation opening. In this way, dirt separation can be improved in a manner known per se.
- the ring has a radially outward-pointing extension which contains the bypass opening. All functions can thus be integrated in a single, stable component.
- the extension is designed in one piece with the ring.
- the extension can be formed in one piece with the ring, for example as a cast part. Due to the one-piece design of the bypass opening with the hollow-cylindrical ring, the bypass is also seamless. This also reduces the tendency to fly away in the bypass. Alternatively, however, it is also possible for the extension to be an additional part that is attached to the ring.
- the ring has a receiving opening for a fiber duct insert in the area of the discharge opening.
- the fiber channel insert directs the separated individual fibers from the opening roller housing to the rotor housing of the spinning device. Because the receiving opening is provided directly in the ring, the fiber channel insert is always received geometrically precisely in the opening roller housing.
- figure 1 shows a schematic, partially sectioned side view of a work station 29 of an open-end spinning machine.
- the work station 29 has, in a manner known per se, an opening roller 2 which is arranged in an opening roller housing 1 and to which a strip-shaped fiber material 5 is fed.
- the fiber material 5 is broken up into individual fibers 7 by the opening roller 2 and fed to an open-end spinning device 3 .
- the open-end spinning device 3 contains a spinning rotor 31 arranged in a rotor housing 30 for spinning the fiber material and is subjected to negative pressure via a negative pressure channel 36 .
- the finished yarn 32 is finally drawn off with a take-off device 33 and fed to a winding device 34 where it is wound onto a spool 35 .
- the opening roller housing 1 is present arranged on a carrier part 13, which is designed as a swivel housing and at the same time includes a cover element (not designated) for the rotor housing 30.
- the carrier part 13 or the swivel housing can be swiveled in the direction of the arrow in order to release access to the rotor housing 30 .
- the carrier part 13 is in turn attached to a machine frame 25 of the open-end spinning machine.
- FIG 2 now shows a detailed representation of an open-end spinning device 3 in a schematic, sectional side view.
- the arrangement of the spinning rotor 31 in the rotor housing 30 and the attachment of the carrier part 13 to the machine frame 25 can be seen in detail again.
- the opening roller housing 1 and the opening roller 2 are even better recognizable.
- the carrier part 13 has a bearing point 22 in which the opening roller 2 is accommodated.
- the opening roller housing 1 comprises a hollow-cylindrical ring 12 which is designed as a self-supporting component and is attached directly to the carrier part 13 of the open-end spinning device 3 .
- the ring 12 is attached directly to its end face 15 facing the carrier part 13.
- the ring 12 is attached to the carrier part 13 by means of fastening means 26, for example screws, shown here only symbolically as a dot-dash line.
- the ring 12 has an inner peripheral wall 10 which surrounds the opening roller 2 arranged in the opening roller housing 1 during operation. Furthermore, the ring has an outer peripheral wall 18 and a further end face 15 facing away from the carrier part 13 .
- FIG 3 shows a schematic, partially sectioned front view of an open-end spinning device 3 with an opening roller housing 1.
- the function and the various functional areas of the opening roller housing 1 are clearly visible in this figure.
- the opening roller housing 1 has, in a manner known per se, a feed opening 4 through which the fiber material 5 (see figure 1 ) is conveyed by means of a feed roller 20 into the opening roller housing 1 and the opening roller 2 is fed.
- the fiber material 5 is combed by the opening roller 2 rotating in the direction of the arrow (not shown here.
- Impurities 9 combed out of the fiber material 5 by the opening roller 2 are thrown out of the opening roller housing 1 by the centrifugal force at the dirt separation opening 8 and can be disposed of. Impurities contained in the fiber material 5 can therefore no longer get into the spinning process and the quality of the yarn 32 produced (see Fig. 1 ) affect.
- the dirt separation opening 8 is connected to the ambient air.
- the inner peripheral wall 10 of the ring 12 of the opening roller housing 1 thus forms at least partially directly a fiber-guiding area in the present opening roller housing 1 .
- the fiber-guiding area 11 is symbolized here by a dotted line and extends from the feed opening 4 via the dirt separation opening 8 to the discharge opening 6.
- the opening roller housing 1 described contains the self-supporting ring 12 as an essential component and thus has a particularly simple and compact form.
- the ring 12 is preferably made of a metal material such as steel or aluminum. As a result, it can be manufactured and installed inexpensively.
- the self-supporting ring 12 can, as already too figure 2 executed, are attached directly to the carrier part 13 of the open-end spinning device 3 and at the same time includes all the essential fiber-guiding surfaces in the fiber-guiding area 11 Figures 7 and 8 is shown. Furthermore, the supply opening 4, the discharge opening 6 and the dirt separation opening 8 are arranged directly in the self-supporting ring 12. It is therefore not necessary to assemble the opening roller housing 1 from several parts, as in the prior art, or to provide it with an additional insert.
- figure 4 shows a schematic front view of an open-end spinning device 3 with an opening roller housing 1 with a plastic cover 16.
- the plastic cover 16 surrounds the opening roller housing 1 and closes it off from the outside, ensures a visually appealing appearance and can also be used to integrate other components or the cover the opening roller housing 1 adjacent functional parts are used.
- the plastic cover 16 shown here extends, for example, up to the rotor housing 30 (not shown here) and creates an attractive transition to it.
- the discharge opening 6 is designed as a receiving opening 24 for a fiber channel insert 27 .
- Such fiber channel inserts 27 are known in the prior art and are customary in order to transport the separated individual fibers 7 to the spinning rotor 31 .
- the fiber channel insert 27 is accommodated directly in the receiving opening 24 of the ring 12, it is geometrically assigned particularly precisely to the opening roller housing 1 and the opening roller 2 rotating therein. Most of the fiber channel insert 27 is covered by the plastic cover 16.
- the ring 12 consists of a metal material such as steel or aluminum.
- the plastic cover 16 can be molded directly onto the ring 12 in a particularly advantageous manner. In this case, the plastic cover 16 is materially connected to the ring 12 . However, the plastic cover 16 could also be connected to the ring 12 by ultrasonic joining or gluing, for example.
- the ring 12 also has form-fitting elements 17 for form-fitting connection with the plastic cover 16, as will be described below.
- the plastic cover 16 seals the opening roller housing 1 from the outside without a gap.
- FIG 5 shows a sectional view along the in figure 4 marked cutting lines in broken representation.
- the ring 12 in the present case has a form-fitting element 17 in the area of its outer peripheral wall 18 .
- the plastic cover 16 is clearly visible in this sectional view.
- the plastic cover 16 it is possible for the plastic cover 16 to be simply pushed onto the ring 12 and pulled over the ring 12 only in the area of the positive-locking element 17 .
- the plastic cover 16 must have a certain elasticity.
- the plastic cover 16 is attached to the ring 12 exclusively by one or more form-fitting elements 17 .
- a plurality of positive-locking elements 17 can be provided both on the peripheral wall 18 and on the end face 15 of the ring 12 facing away from the carrier part 13 .
- figure 6 also shows a sectional view along the in figure 4 marked cutting lines in broken representation, but includes an alternative form of connection between the ring 12 and the plastic cover 16.
- the plastic cover 16 has two clip elements 19 for connection to the ring 12 in the present example.
- the plastic cover 16 is held on the ring 12 in a purely form-fitting manner.
- the clip elements 19 are arranged on the plastic cover 16 in an elastically yielding manner and therefore do not impede the assembly of the plastic cover 16 on the ring 12 .
- the clip elements 19 then each interact with a latching shoulder 28 which is provided in the ring 12 .
- FIG 7 now shows a first embodiment of a ring 12 of an opening roller housing 1 in a schematic front view.
- the opening roller housing 1 shown here or the ring 12 also has a bypass opening 21 for supplying an inlet air flow into the opening roller housing 1 .
- the air supply through the dirt separation opening 8 into the opening roller housing 1 is limited by means of the bypass opening 21, so that the dirt particles contained in the fiber material 5 to be opened can be separated better. In particular, this makes it possible to also separate lighter dirt particles which would otherwise be entrained with the air flow in the opening roller housing 1 and would remain in the fiber material 5 .
- the bypass opening 21 is arranged in an extension 23 of the ring 12 .
- the bypass opening 21 is thus advantageously integrated in one piece into the opening roller housing 1 .
- the ring 12 has a further extension 23, which delimits the dirt separation opening.
- Even more functions are thus combined in a single component, which simplifies both production and assembly.
- On such a ring 12 can be easily produced, for example, as a cast part, in particular as an injection-molded part.
- the surfaces in the fiber-guiding area 11 can also be additionally processed in order to achieve a high surface quality and/or be provided with an anti-wear coating, which incidentally also applies to all versions of the ring 12 shown in other figures.
- a total of four fastening bores 14 for fastening the ring 12 to the carrier part 13 (see figure 2 ) recognizable.
- These fastening bores 14 are preferably designed as threads, so that the ring 12 can be screwed directly to the carrier part 13 by means of several screws.
- a seamless connection can also be created here thanks to the contact pressure of the screws.
- figure 8 now shows a schematic front view of a further embodiment of a ring 12, which, like the one in figure 7 includes an extension 23 with a bypass opening 21 shown.
- Form-locking elements 17 are shown on this ring, which are also arranged in the area of an outer peripheral wall 18 . As already described in relation to FIG. 5, these can be provided both in addition to an integral connection with the plastic cover 16 in order to give it further support, or as the sole means of connection to the plastic cover 16.

Description
Die vorliegende Erfindung betrifft ein Auflösewalzengehäuse für eine Auflösewalze einer Offenend-Spinnvorrichtung mit einer Zuführöffnung zum Zuführen eines Fasermaterials in das Auflösewalzengehäuse, mit einer Abfuhröffnung zum Abführen aufgelöster Einzelfasern aus dem Auflösewalzengehäuse, mit einer Schmutzabscheideöffnung zum Abscheiden von Verunreinigungen aus dem Fasermaterial sowie mit einer die Auflösewalze im Betrieb umgebenden inneren Umfangswand mit einem faserführenden Bereich, welcher sich von der Zuführöffnung über die Schmutzabscheideöffnung bis zur Abfuhröffnung erstreckt, wobei das Auflösewalzengehäuse einen hohlzylindrischen Ring umfasst.The present invention relates to an opening roller housing for an opening roller of an open-end spinning device with a feed opening for feeding a fiber material into the opening roller housing, with a discharge opening for removing dissolved individual fibers from the opening roller housing, with a dirt separation opening for separating impurities from the fiber material and with a the opening roller surrounding inner peripheral wall during operation with a fiber-guiding area, which extends from the feed opening via the dirt separation opening to the discharge opening, wherein the opening roller housing comprises a hollow cylindrical ring.
Auflösewalzengehäuse sind im Stand der Technik in verschiedenen Ausführungen bekannt geworden und werden an Offenend-Spinnvorrichtungen eingesetzt, um ein der Auflösevorrichtung zugeführtes bandförmiges Fasermaterial in Einzelfasern aufzulösen und die aufgelösten Einzelfasern dann der Spinnvorrichtung zuzuführen.Opening roller housings have become known in various designs in the prior art and are used on open-end spinning devices in order to open up a ribbon-shaped fiber material fed to the opening device into individual fibers and then to feed the opened up individual fibers to the spinning device.

Aufgabe der vorliegenden Erfindung ist es daher, ein Auflösewalzengehäuse vorzuschlagen, welches einfach herstellbar und montierbar ist und zudem Verflugungen des Auflösewalzengehäuses vermeidet.The object of the present invention is therefore to propose an opening roller housing which is easy to manufacture and assemble and which also avoids warping of the opening roller housing.
Die Aufgabe wird gelöst durch ein Auflösewalzengehäuse und eine Offenendspinnvorrichtung mit den Merkmalen der unabhängigen Patentansprüche.The object is achieved by an opening roller housing and an open-end spinning device with the features of the independent patent claims.
Ein Auflösewalzengehäuse für eine Auflösewalze einer Offenend-Spinnvorrichtung weist eine Zuführöffnung zum Zuführen eines Fasermaterials in das Auflösewalzengehäuse, eine Abfuhröffnung zum Abführen aufgelöster Einzelfasern aus dem Auflösewalzengehäuse, eine Schmutzabscheideöffnung zum Abscheiden von Verunreinigungen aus dem Fasermaterial sowie eine die Auflösewalze im Betrieb umgebende innere Umfangswand mit einem faserführenden Bereich auf, welcher sich von der Zuführöffnung über die Schmutzabscheideöffnung bis zur Abfuhröffnung erstreckt. Das Auflösewalzengehäuse umfasst dabei einen hohlzylindrischen Ring.An opening roller housing for an opening roller of an open-end spinning device has a feed opening for feeding a fiber material into it opening roller housing, a discharge opening for removing dissolved individual fibers from the opening roller housing, a dirt separation opening for separating impurities from the fiber material and an inner peripheral wall surrounding the opening roller during operation with a fiber-guiding area which extends from the feed opening via the dirt separation opening to the discharge opening. The opening roller housing comprises a hollow-cylindrical ring.
Es wird vorgeschlagen, dass der hohlzylindrische Ring als selbsttragendes Bauteil ausgeführt ist, welches direkt an einem Trägerteil der Offenend-Spinnvorrichtung befestigbar ist und welches sowohl die innere Umfangswand mit dem faserführenden Bereich als auch die Zuführöffnung, die Abfuhröffnung und die Schmutzabscheideöffnung enthält.It is proposed that the hollow-cylindrical ring is designed as a self-supporting component which can be attached directly to a support part of the open-end spinning device and which contains both the inner peripheral wall with the fiber-guiding area and the feed opening, the discharge opening and the dirt separation opening.
Anders als im Stand der Technik weist das vorgeschlagene Auflösewalzengehäuse somit keinen zusätzlichen Einsatz mehr auf. Um eine Anpassung an verschiedene Fasermaterialien oder verschiedene Spinnbedingungen vorzunehmen, ist es daher erforderlich, das gesamte Auflösewalzengehäuse auszutauschen. Da das ringförmige Auflösewalzengehäuse jedoch den Grundkörper des Auflösewalzengehäuse bildet und direkt an dem Trägerteil befestigbar ist, kann dies einfach und schnell bewerkstelligt werden. Da zudem das ringförmige Auflösewalzengehäuse auf die wesentlichen Funktionen, nämlich das Zurverfügungstellen der genannten Öffnungen sowie faserführenden Bereiches, reduziert ist, und eine sehr kompakte Form aufweist, kann das Auflösewalzengehäuse dennoch kostengünstig hergestellt werden. Da das ringförmige Auflösewalzengehäuse einteilig ausgeführt ist, sind zudem keinerlei Spalte vorhanden, an welchen Fasern anhaften könnten. Die Verflugungsneigung des Auflösewalzengehäuses ist somit reduziert.In contrast to the prior art, the proposed opening roller housing therefore no longer has an additional insert. In order to adapt to different fiber materials or different spinning conditions, it is therefore necessary to replace the entire opening roller housing. However, since the ring-shaped opening roller housing forms the main body of the opening roller housing and can be fastened directly to the carrier part, this can be done quickly and easily. In addition, since the ring-shaped opening roller housing is reduced to the essential functions, namely the provision of the openings mentioned and the fiber-guiding area, and has a very compact shape, the opening roller housing can nevertheless be manufactured inexpensively. Since the ring-shaped opening roller housing is designed in one piece, there are also no gaps to which fibers could adhere. The tendency of the opening roller housing to fly is thus reduced.
Besonders vorteilhaft ist es, wenn der Ring Befestigungsbohrungen, insbesondere Gewinde, zu seiner Befestigung an dem Trägerteil der Offenend-Spinnvorrichtung aufweist.It is particularly advantageous if the ring has fastening bores, in particular threads, for fastening it to the carrier part of the open-end spinning device.
Besonders vorteilhaft ist es, wenn der Ring Befestigungsbohrungen, insbesondere Gewinde, zu seiner Befestigung an dem Trägerteil der Offenend-Spinnvorrichtung aufweist. Das Auflösewalzengehäuse kann hierdurch in einfacher Weise durch Verschrauben an dem Träger befestigt werden. Durch die Verschraubung können dabei hohe Antriebskräfte erzeugt werden, sodass das Auflösewalzengehäuse nahezu spaltfrei an dem Trägerteil befestigt werden kann. Die Verflugungsneigung wird hierdurch weiter reduziert.It is particularly advantageous if the ring has fastening bores, in particular threads, for fastening it to the carrier part of the open-end spinning device. The opening roller housing can hereby be attached to the carrier in a simple manner by screwing. High driving forces can be generated by screwing, so that the opening roller housing can be fastened to the carrier part with almost no gaps. This further reduces the tendency to fly away.
Die Befestigungsbohrungen können dabei als Durchgangsbohrungen ausgeführt sein, sodass das Auflösewalzengehäuse von der Vorderseite der Spinnvorrichtung her montiert werden kann.The mounting holes can be designed as through holes, so that the opening roller housing can be mounted from the front of the spinning device.
Nach einer anderen Ausführung kann es jedoch auch vorteilhaft sein, wenn die Befestigungsbohrungen als Sacklochbohrungen und insbesondere als Gewinde ausgeführt sind. Die Befestigung kann in diesem Fall von einer Rückseite des Trägerteils der Offenend-Spinnvorrichtung her erfolgen. Dies ist beispielsweise dann vorteilhaft, wenn das Trägerteil ein von der Offenend-Spinnvorrichtung abklappbares Schwenkgehäuse ist.According to another embodiment, however, it can also be advantageous if the fastening bores are designed as blind bores and, in particular, as threads. In this case, the fastening can take place from a rear side of the carrier part of the open-end spinning device. This is advantageous, for example, when the carrier part is a pivoting housing that can be folded away from the open-end spinning device.
Vorteilhaft ist es zudem, wenn die Befestigungsbohrungen an einer Stirnfläche des Rings angeordnet sind. Die Form des Rings kann hierdurch weiterhin sehr kompakt gehalten werden, da keinerlei zusätzliche Befestigungslaschen erforderlich sind. Die spaltfreie Befestigung des Auflösewalzengehäuses an dem Trägerteil kann hierdurch noch weiter unterstützt werden.It is also advantageous if the fastening bores are arranged on an end face of the ring. As a result, the shape of the ring can still be kept very compact, since no additional fastening straps are required. The gap-free attachment of the opening roller housing to the carrier part can be supported even further as a result.
Vorteilhaft ist es, wenn das Auflösewalzengehäuse weiterhin eine den Ring umgebende Kunststoffabdeckung umfasst. Die Kunststoffabdeckung stellt dabei einerseits einen optisch ansprechenden Übergang zu dem Trägerteil der Offen-Endspinnvorrichtung her. Andererseits kann die Kunststoffabdeckung der Integration und/oder der Abdeckung weiterer Bauteile wie beispielsweise eines Faserkanaleinsatzes dienen.It is advantageous if the opening roller housing also includes a plastic cover surrounding the ring. On the one hand, the plastic cover creates a visually appealing transition to the carrier part of the open-end spinning device. On the other hand, the plastic cover can be used to integrate and/or cover other components such as a fiber duct insert.

On the one hand, the plastic cover creates a visually appealing transition to the carrier part of the open-end spinning device. On the other hand, the plastic cover can be used to integrate and/or cover other components such as a fiber duct insert.
Ebenso ist es vorteilhaft, wenn die Kunststoffabdeckung stoffschlüssig mit dem Ring verbunden ist, insbesondere direkt an den hohlzylindrischen Ring angespritzt ist. Das Auflösewalzengehäuse ist hierdurch auch bei Verwendung unterschiedlicher Materialien für den hohlzylindrischen Ring und die Kunststoffabdeckung einteilig ausgeführt. Das Auflösewalzengehäuse wird dabei durch die Kunststoffabdeckung spaltfrei abgeschlossen, sodass die Gefahr, dass Fasern an Spalten anhaften noch weiter reduziert wird. Die stoffschlüssige Verbindung kann insbesondere durch direktes Anspritzen der Kunststoffabdeckung an den hohlzylindrischen Ring erfolgen. Ebenfalls denkbar ist es jedoch auch, die beiden Teile miteinander zu verschweißen, beispielsweise durch Ultraschallschweißen. Auch eine Verklebung kommt weiterhin infrage.It is also advantageous if the plastic cover is integrally connected to the ring, in particular is injection molded directly onto the hollow-cylindrical ring. As a result, the opening roller housing is made in one piece even when using different materials for the hollow cylindrical ring and the plastic cover. The opening roller housing is closed off with no gaps by the plastic cover, further reducing the risk of fibers sticking to gaps. The integral connection can be made in particular by direct injection molding of the plastic cover onto the hollow-cylindrical ring. However, it is also conceivable to weld the two parts together, for example by ultrasonic welding. Bonding is also still an option.
Vorteilhaft ist es, wenn der Ring ein oder mehrere Formschlusselemente zur formschlüssigen Verbindung mit der Kunststoffabdeckung aufweist, wobei vorzugsweise das oder die Formschlusselemente an einer äußeren Umfangswand des Rings angeordnet ist/sind. Derartige Formschlusselemente können auch bei einer stoffschlüssigen Verbindung wie zuvor beschrieben vorteilhaft sein. Mittels der Formschlusselemente wird zusätzlich noch ein Formschluss zwischen dem hohlzylindrischen Ring und der Kunststoffabdeckung hergestellt. Die Kunststoffabdeckung ist hierdurch besonders gut an dem hohlzylindrischen Ring fixiert. Sind die Formschlusselemente an der äußeren Umfangswand des Ringes angebracht, so liegen diese außerhalb von Funktionsflächen bzw. Funktionsbereichen. Es ist jedoch auch denkbar, Formschlusselemente insbesondere an der vorderen, also in montiertem Zustand des Auflösewalzengehäuses nach außen weisenden Stirnfläche des Rings anzubringen.It is advantageous if the ring has one or more form-fitting elements for form-fitting connection to the plastic cover, with the form-fitting element or elements preferably being/are arranged on an outer peripheral wall of the ring. Such positive-locking elements can also be advantageous in the case of a material-to-material connection as described above. By means of the form-fitting elements, an additional Form fit between the hollow cylindrical ring and the plastic cover made. As a result, the plastic cover is particularly well fixed to the hollow-cylindrical ring. If the form-fitting elements are attached to the outer peripheral wall of the ring, then they are outside of functional surfaces or functional areas. However, it is also conceivable to attach positive-locking elements in particular to the front face of the ring, that is to say the face of the ring which faces outwards when the opening roller housing is in the assembled state.
Nach einer anderen Ausführung ist es vorteilhaft, wenn die Kunststoffabdeckung ein oder mehrere Clipelemente zur Verbindung mit dem Ring aufweist. Die Kunststoffabdeckung ist in diesem Fall lösbar mit dem Ring verbunden. Die Clipelemente rasten dabei in eine korrespondierend zu den Clipelementen geformte Rastschulter des Ringes ein. Je nach Art der Herstellung des Ringes und der Kunststoffabdeckung kann diese Ausführung Vorteile bieten. Auch in diesem Fall bildet jedoch der hohlzylindrische Ring den Grundkörper des Auflösewalzengehäuses, welcher die Kunststoffabdeckung trägt. Die Vorteile der einfachen Befestigung werden somit auch mit dieser Ausführung erreicht.According to another embodiment, it is advantageous if the plastic cover has one or more clip elements for connection to the ring. In this case, the plastic cover is detachably connected to the ring. The clip elements snap into a snap-in shoulder of the ring that is shaped to correspond to the clip elements. Depending on how the ring and the plastic cover are manufactured, this design can offer advantages. In this case too, however, the hollow-cylindrical ring forms the base body of the opening roller housing, which carries the plastic cover. The advantages of simple attachment are thus also achieved with this design.
Des Weiteren ist es vorteilhaft, wenn der Ring aus einem metallischen Material, insbesondere einem Stahl- oder Aluminiummaterial, besteht und vorzugsweise als Gussteil ausgeführt ist. Durch die Ausführung aus einem Stahl oder Aluminiummaterial kann der hohlzylindrische Ring stabil und verschleißfest ausgeführt werden und kann deshalb auch direkt die faserführenden Flächen des Auflösewalzengehäuses bilden. Durch die Ausführung als Gussteil sind dabei auch nicht vollständig runde Formgebungen, Formgebungen mit Fortsätzen sowie die Integration weiterer Funktionen möglich.Furthermore, it is advantageous if the ring consists of a metallic material, in particular a steel or aluminum material, and is preferably designed as a cast part. By being made of a steel or aluminum material, the hollow-cylindrical ring can be made stable and wear-resistant and can therefore also directly form the fiber-guiding surfaces of the opening roller housing. Due to the design as a cast part, shapes that are not completely round, shapes with extensions and the integration of other functions are also possible.
Vorteilhaft ist es weiterhin, wenn der hohlzylindrische Ring spanend bearbeitet ist. Auch ein als Gussteil ausgeführter Ring kann dabei einfach und genau spannend nachbearbeitet sein. Insbesondere die faserführenden Flächen sowie gegebenenfalls luftführende Flächen können hierdurch mit einer hohen Oberflächengüte und einer großen Genauigkeit hergestellt werden.It is also advantageous if the hollow-cylindrical ring is machined. A ring designed as a cast part can also be easily and precisely be reworked in an exciting way. In particular, the fiber-guiding surfaces and optionally air-guiding surfaces can be produced with a high surface quality and great accuracy.
Vorteilhaft ist es auch, wenn die innere Umfangswand des Rings zumindest in dem faserführenden Bereich mit einer Beschichtung, insbesondere einer Verschleißschutzbeschichtung, versehen ist. Die Standzeit des Auflösewalzengehäuses können hierdurch verbessert werden. Weiterhin können mit einer Beschichtung auch die Oberflächengüte sowie Strömungseigenschaften und Faserleiteigenschaften des Ringes verbessert werden.It is also advantageous if the inner peripheral wall of the ring is provided with a coating, in particular an anti-wear coating, at least in the fiber-guiding area. This can improve the service life of the opening roller housing. Furthermore, a coating can also be used to improve the surface quality as well as the flow properties and fiber guidance properties of the ring.
Besonders vorteilhaft ist es, wenn der Ring weiterhin eine Bypassöffnung zum Zuführen eines Zuluftstromes in das Auflösewalzengehäuse enthält. Die Bypassöffnung dient dazu, dem Auflösewalzengehäuse zusätzliche Luft zuzuführen, sodass weniger Luft über die Schmutzabscheideöffnung angesaugt werden muss. Die Schmutzabscheidung kann hierdurch in an sich bekannter Weise verbessert werden.It is particularly advantageous if the ring also contains a bypass opening for supplying an inlet air flow into the opening roller housing. The bypass opening is used to supply additional air to the opening roller housing so that less air has to be sucked in through the dirt separation opening. In this way, dirt separation can be improved in a manner known per se.
Dabei ist es vorteilhaft, wenn der Ring einen radial nach außen weisenden Fortsatz aufweist, welcher die Bypassöffnung enthält. Es können somit sämtliche Funktionen in einem einzigen, stabilen Bauteil integriert werden.It is advantageous if the ring has a radially outward-pointing extension which contains the bypass opening. All functions can thus be integrated in a single, stable component.
Besonders vorteilhaft ist es dabei, wenn der Fortsatz einteilig mit dem Ring ausgebildet ist. Der Fortsatz kann beispielsweise als Gussteil einteilig mit dem Ring geformt sein. Durch die einteilige Ausführung der Bypassöffnung mit dem hohlzylindrischen Ring ist auch der Bypass fugenlos ausgeführt. Hierdurch wird die Verflugungsneigung im Bypass ebenfalls reduziert. Alternativ ist es jedoch auch möglich, dass der Fortsatz ein zusätzliches Teil ist, das an den Ring angesetzt wird.It is particularly advantageous if the extension is designed in one piece with the ring. The extension can be formed in one piece with the ring, for example as a cast part. Due to the one-piece design of the bypass opening with the hollow-cylindrical ring, the bypass is also seamless. This also reduces the tendency to fly away in the bypass. Alternatively, however, it is also possible for the extension to be an additional part that is attached to the ring.
Des Weiteren ist es vorteilhaft, wenn der Ring im Bereich der Abfuhröffnung eine Aufnahmeöffnung für einen Faserkanaleinsatz aufweist. Der Faserkanaleinsatz leitet in an sich bekannter Weise die aufgelösten Einzelfasern von dem Auflösewalzengehäuse zu dem Rotorgehäuse der Spinnvorrichtung. Dadurch, dass die Aufnahmeöffnung direkt in dem Ring vorgesehen ist, wird der Faserkanaleinsatz stets geometrisch genau in dem Auflösewalzengehäuse aufgenommen.Furthermore, it is advantageous if the ring has a receiving opening for a fiber duct insert in the area of the discharge opening. In a manner known per se, the fiber channel insert directs the separated individual fibers from the opening roller housing to the rotor housing of the spinning device. Because the receiving opening is provided directly in the ring, the fiber channel insert is always received geometrically precisely in the opening roller housing.
Die genannten Vorteile, insbesondere die Kostenvorteile, die auf vereinfachte Montage und die reduzierte Verfügungsneigung werden auch bei einer offenen Spinnvorrichtung mit einem derartigen Auflösewalzengehäuse erreicht, sodass diese ebenfalls Schutz beansprucht wird.The advantages mentioned, in particular the cost advantages, the simplified assembly and the reduced availability are also achieved with an open spinning device with such an opening roller housing, so that protection is also claimed for it.
