Definitions
- the present invention relates to an opening roller housing of a opening device of an open-end rotor spinning device with a feed opening for feeding the fiber sliver, with a removal opening for removing fibers from the opening roller housing, and with a dirt separation opening in the peripheral wall of the opening roller housing.
- a fiber sliver is dissolved into individual fibers by means of an opening roller device.
- the fibers are loosened by means of a disintegration roller which, as a result of, for example, a toothed clothing, dissolves the sliver presented to it by combing it out into individual fibers.
- This opening process takes place in a opening roller housing, in which the opening roller is rotatably arranged and where the sliver is fed to the opening roller with a feed device through a feed opening of the opening roller housing.
- a dirt separating opening is present after the feed opening.
- the dirt for example in the case of natural fibers such as cotton or in the case of cotton / chemical fiber mixtures, dust, nits, shell residues or the like, is thrown out through this opening and thus leaves the fiber stream aimed at the fiber guide channel.
- a discharge opening is arranged after the dirt separation opening, through which the separated fibers are led out of the opening roller housing.
- the fibers then pass through a fiber guide channel into the spinning rotor, where they are spun.
- an opening roller housing is known in which the peripheral wall the opening roller housing between the dirt separator and the discharge opening for fibers is formed by an exchangeable insert. This should allow the dirt separation to be adapted to different fibers.
- This opening roller housing has the disadvantage that the size of the dirt separation can be varied, but the known use is not suitable for making opening roller housings variable, so that they can be adapted to different fiber materials and other spinning conditions.
- the opening roller housings of the opening devices essentially consist of individual segments which are arranged on a carrier plate.
- the individual segments placed on the carrier plate thus form the peripheral wall of the opening roller housing.
- an insert extends into the area of the dirt separation opening and partially forms the peripheral wall of the opening roller housing in the area of the dirt separation opening.
- the disadvantage here is the complex design of the insert. It also disturbs that the outer contour of the insert is flush with the inner surface of the peripheral wall of the opening roller housing, so that the annular gap between opening roller and insert cannot be changed in the radial direction.
- the present invention is based on the object of specifying an insert for an opening roller housing which is structurally simple and easy to assemble and disassemble, in particular to be replaced. Furthermore, the use should be simple and inexpensive to manufacture. In addition, the exchange should allow adjustment to different spinning conditions.
- an opening roller housing for an opening device of an open-end rotor spinning device with a feed opening for feeding a fiber band, with a removal opening for removing fibers from the opening roller housing and with a dirt separating opening in the peripheral wall of the opening roller housing.
- the opening roller housing includes an interchangeable insert.
- the insert is designed as a hollow cylinder-like ring which has at least one wall region with an opening and a trough-shaped fiber inlet in the discharge opening in the cylinder wall and a wall region with an opening for adjusting the dirt separating opening.
- the insert also adjusts the annular gap between the opening roller housing of an opening roller through the thickness of its cylinder wall.
- the opening roller housing according to the invention shows an efficient and simple possibility of enabling adjustment to different spinning conditions.
- the length and shape of the fiber inlet in the circumferential direction of the ring can be varied by simply exchanging the ring. With a trough-shaped fiber inlet, the inlet area can take place substantially in front of the fiber guide channel.
- the size of the opening of the insert for adjusting the dirt separating opening can also be varied.
- the annular gap between the opening roller and the insert can be varied by exchanging the ring. Inserts with different inside diameters of the inner cavity of the insert can be used for this.
- the corresponding optimal ring can be used for different fibers and applications.
- the rings allow a different fiber inlet area of the fiber guide channel. Another advantage is to close or open the dirt separation opening more or less.
- the annular gap between the opening roller and the ring can also be varied if necessary.
- the use according to the invention is particularly suitable for simply selecting the appropriate fiber guide channel inlet area by simply changing the ring and / or influencing the dirt separation area in such a way that the user can decide how clean his yarn should be.
- the insert according to the invention is preferably formed in one piece. This enables simple manufacture and assembly.
- the insert forms the boundary of the feed opening and / or the dirt separating opening on at least three sides.
- the insert forms the boundary of the discharge opening.
- the insert is arranged coaxially with the opening roller.
- the insert is preferably arranged coaxially to the peripheral wall.
- the insert preferably has a circumferential step which forms a labyrinth seal with the cover.
- the insert protects the housing from wear.
- the insert is preferably protected against wear in order to ensure a long service life.
- the insert can also be replaced easily and inexpensively in the event of wear.
- FIG. 1 an open-end rotor spinning device 1 is shown schematically.
- Such open-end rotor spinning devices each have a rotor housing 2 in which the spinning cup of a spinning rotor 3 rotates at high speed.
- the spinning rotor 3 is supported, for example, with a rotor shaft 4 in the bearing gussets of a so-called support disk bearing 5 and is supported by a machine-long one Tangential belt 6, which is acted upon by a pressure roller 7, driven by friction.
- the rotor shaft 4 is axially fixed, for example, by a permanent magnetic axial bearing 18.
- the rotor housing 2, which is open towards the front, is closed during the spinning operation by a pivotably mounted cover element 8, into which a channel plate is inserted, which is provided with a circumferential center seal 9 on Rotor housing 2 is present.
- the rotor housing 2 is also connected via a corresponding vacuum line 10 to a vacuum source 11, which generates the spinning vacuum required in the rotor housing 2.
- a channel plate adapter 12 is interchangeably arranged in a receptacle of the channel plate (not shown), which has the mouth region of a fiber guide channel 14 and a thread take-off nozzle 13, to which a thread take-off roller 15 is connected.
- an opening device 26 is integrated in the cover element 8, which is mounted such that it can be rotated to a limited extent about a pivot axis 16.
- the cover element 8 has an opening roller housing 17 and rear-side bearing brackets 19, 20 for mounting an opening roller 21 or a feed roller 22. With 30 a cover of the opening roller housing 17 is designated.
- the opening roller 21 is driven by a rotating, machine-long tangential belt 24, which acts on a whorl 23 of the opening roller 21, while the feed roller 22 is preferably driven by a machine-long drive shaft 25 or a worm gear (not shown).
- FIG. 2 A preferred embodiment of the opening roller housing 17 according to the invention is shown.
- the sliver, the opening roller 21 (see Fig. 1 ) and the individual fibers have been omitted to illustrate the invention.
- the opening roller housing 17 and the opening device 26 are shown in section and have a feed opening 27 for the fiber sliver to be opened, as well as a dirt separating opening 28 and a discharge opening 29 for discharging the combed and separated fibers through the fiber guide channel 14 connected to the opening roller housing 17 to the spinning station (see Fig. 1 ).
- the dirt separating opening 28 is delimited by the housing side wall and by the walls 31.1 and 31.2, which are part of the opening roller housing 17.
- the dirt separating opening 28 leads via a dirt discharge channel 32 to a collection or removal system (not shown here) for the separated dirt particles.
- the feed trough 34 is rotatably mounted about a pin 35 on the housing wall.
- the feed trough 34 is supported by a spring 36 and pressed against the feed roller 22. If the state of the sliver changes, for example its strength, the feed trough 34 deflects downward.
- an opening roller 21 rotates in partial direction B about its axis, which is mounted in the opening roller housing 17.
- the opening roller 21 carries on its circumference a (not shown) opening set, which in the present case is sawtooth-shaped. This opening set combs individual fibers from the sliver fed. Due to the air flow prevailing in the opening roller housing 17, the individual fibers are carried along with the air flow and fed through the fiber guide channel 14 to the spinning unit.
- the dirt separated from the stream of the separated fibers generally has a greater mass than the fibers and is therefore thrown out essentially tangentially from the dirt separating opening 28.
- An opening 38 for the passage of the shaft of the opening roller 21 can be seen in the chamber 37 of the opening roller housing 17.
- the insert 40 according to the invention is arranged in the chamber 37 of the opening roller housing 17.
- the insert 40 is coaxial with the opening roller 21 (see Fig. 1 ) and arranged to the peripheral wall 39.
- the insert 40 is by means of (not shown) fasteners, for. B. screws or dowel pins, interchangeably attached to the side wall of the opening roller housing 17.
- the insert 40 is after Fig. 2 and 3rd formed as a hollow cylinder-like ring 41 with a cylinder wall 42 and an inner cavity 43.
- the insert 40 has one in the cylinder wall 42 Wall area with a continuous first opening 44 and a fiber inlet 45.
- the length of the fiber inlet 45 extends over approximately one third of the circumference of the annular insert 40.
- the fiber inlet 45 is delimited in the axial direction by regions of the cylinder wall 42 and in the circumferential direction at one end by the discharge opening 29.
- the other end of the fiber inlet 45 slides smoothly into the cylinder wall 42 in the circumferential direction, as a result of which a stepless fiber run is achieved.
- the fiber inlet 45 is trough-shaped with a base area and two curved side walls.
- the insert 40 has a wall region in the cylinder wall 42 with a continuous second opening 46.
- the second opening 46 lies opposite the feed opening 27 and the dirt separating opening 28 and allows both the passage of dissolved fibers to the opening roller 21 and the passage of separated dirt from the annular gap into the dirt separating opening 28.
- the cylinder wall 42 forms the boundary of the second opening 46 three pages.
- the second opening 46 is open on the fourth side.
- the ring 41 has a circumferential step 47, which forms a labyrinth seal with the cover 30 of the opening roller housing 17.

Description
Gegenstand der vorliegenden Erfindung ist ein Auflösewalzengehäuse einer Auflösevorrichtung einer Offenend-Rotorspinnvorrichtung mit einer Zuführöffnung für das Zuführen des Faserbands, mit einer Abfuhröffnung für das Abführen von Fasern aus dem Auflösewalzengehäuse, sowie mit einer Schmutzabscheideöffnung in der Umfangswand des Auflösewalzengehäuses.The present invention relates to an opening roller housing of a opening device of an open-end rotor spinning device with a feed opening for feeding the fiber sliver, with a removal opening for removing fibers from the opening roller housing, and with a dirt separation opening in the peripheral wall of the opening roller housing.
Zur Vorbereitung des Verspinnens von faserförmigem Gut zu Garnen wird bei Offenend-Spinnvorrichtungen ein Faserband mittels einer Auflösewalzeneinrichtung zu Einzelfasern aufgelöst. Das Auflösen der Fasern geschieht durch eine Auflösewalze, die infolge bspw. einer gezahnten Garnitur an ihrem Umfang das ihr vorgelegte Faserband durch Auskämmen in Einzelfasern auflöst. Dieser Auflöseprozess geschieht in einem Auflösewalzengehäuse, in dem die Auflösewalze drehbar angeordnet und wo durch eine Zuführöffnung des Auflösewalzengehäuses das Faserband mit einer Speisevorrichtung der Auflösewalze zugeführt wird.To prepare the spinning of fibrous material into yarns in open-end spinning devices, a fiber sliver is dissolved into individual fibers by means of an opening roller device. The fibers are loosened by means of a disintegration roller which, as a result of, for example, a toothed clothing, dissolves the sliver presented to it by combing it out into individual fibers. This opening process takes place in a opening roller housing, in which the opening roller is rotatably arranged and where the sliver is fed to the opening roller with a feed device through a feed opening of the opening roller housing.
In Umfangsrichtung der sich drehenden Auflösewalze betrachtet ist nach der Zuführöffnung eine Schmutzabscheideöffnung vorhanden. Der Schmutz, bspw. bei Naturfasern wie Baumwolle oder bei Baumwolle/Chemiefasermischungen, Staub, Nissen, Schalenreste oder dergleichen, wird durch diese Öffnung herausgeschleudert und verlässt damit den dem Faserleitkanal zustrebenden Faserstrom.When viewed in the circumferential direction of the rotating opening roller, a dirt separating opening is present after the feed opening. The dirt, for example in the case of natural fibers such as cotton or in the case of cotton / chemical fiber mixtures, dust, nits, shell residues or the like, is thrown out through this opening and thus leaves the fiber stream aimed at the fiber guide channel.
Weiterhin in Umfangsrichtung gesehen ist nach der Schmutzabscheideöffnung eine Abfuhröffnung angeordnet, durch welche die vereinzelten Fasern aus dem Auflösewalzengehäuse herausgeführt werden. Durch einen Faserleitkanal hindurch gelangen die Fasern dann in den Spinnrotor, wo sie versponnen werden.Furthermore, seen in the circumferential direction, a discharge opening is arranged after the dirt separation opening, through which the separated fibers are led out of the opening roller housing. The fibers then pass through a fiber guide channel into the spinning rotor, where they are spun.

Aus der
Es ist bekannt, dass die Auflösewalzengehäuse der Auflösevorrichtungen im Wesentlichen aus einzelnen Segmenten bestehen, die auf einer Trägerplatte angeordnet sind. Die einzelnen, auf die Trägerplatte aufgesetzten Segmente bilden somit die Umfangswand des Auflösewalzengehäuses. In der
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Einsatz für ein Auflösewalzengehäuse anzugeben, der konstruktiv einfach ist und leicht zu montieren sowie zu demontieren, insbesondere auszutauschen ist. Des Weiteren soll der Einsatz einfach und kostengünstig herstellbar sein. Außerdem soll der Austausch eine Einstellung auf verschiedene Spinnbedingungen ermöglichen.Proceeding from this, the present invention is based on the object of specifying an insert for an opening roller housing which is structurally simple and easy to assemble and disassemble, in particular to be replaced. Furthermore, the use should be simple and inexpensive to manufacture. In addition, the exchange should allow adjustment to different spinning conditions.
Diese Aufgabe wird erfindungsgemäß durch ein Auflösewalzengehäuse mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen des erfindungsgemäßen Auflösewalzengehäuses sind Gegenstand der abhängigen Ansprüche.This object is achieved according to the invention by an opening roller housing with the features of claim 1. Advantageous developments and refinements of the opening roller housing according to the invention are the subject of the dependent claims.
Die in den abhängigen formulierten Ansprüchen einzeln aufgeführten Merkmale können in beliebiger, technologisch sinnvoller Weise miteinander kombiniert werden und weitere Ausgestaltungen der Erfindung definieren. Darüber hinaus werden die in den Ansprüchen angegebenen Merkmale in der Beschreibung näher präzisiert und erläutert, wobei weitere bevorzugte Ausführungsbeispiele der Erfindung dargestellt werden.The features listed individually in the dependent formulated claims can be combined with one another in any technologically meaningful manner and define further refinements of the invention.

Erfindungsgemäß wird ein Auflösewalzengehäuse für eine Auflösevorrichtung einer Offenend-Rotorspinnvorrichtung vorgeschlagen mit einer Zuführöffnung für das Zuführen eines Faserbands, mit einer Abfuhröffnung für das Abführen von Fasern aus dem Auflösewalzengehäuse sowie mit einer Schmutzabscheideöffnung in der Umfangswand des Auflösewalzengehäuses. Das Auflösewalzengehäuse umfasst einen austauschbaren Einsatz. Der Einsatz ist als hohlzylinderartiger Ring ausgebildet, der in der Zylinderwand zumindest einen Wandbereich mit einer Öffnung und einem muldenförmigen Fasereinlauf in die Abfuhröffnung und einen Wandbereich mit einer Öffnung zur Einstellung der Schmutzabscheideöffnung aufweist. Weiter stellt der Einsatz durch die Dicke seiner Zylinderwand den Ringspalt zwischen dem Auflösewalzengehäuse einer Auflösewalze ein.According to the invention, an opening roller housing for an opening device of an open-end rotor spinning device is proposed with a feed opening for feeding a fiber band, with a removal opening for removing fibers from the opening roller housing and with a dirt separating opening in the peripheral wall of the opening roller housing. The opening roller housing includes an interchangeable insert. The insert is designed as a hollow cylinder-like ring which has at least one wall region with an opening and a trough-shaped fiber inlet in the discharge opening in the cylinder wall and a wall region with an opening for adjusting the dirt separating opening. The insert also adjusts the annular gap between the opening roller housing of an opening roller through the thickness of its cylinder wall.
Durch das erfindungsgemäße Auflösewalzengehäuse wird eine effiziente und einfache Möglichkeit aufgezeigt, eine Einstellung auf verschiedene Spinnbedingungen zu ermöglichen.The opening roller housing according to the invention shows an efficient and simple possibility of enabling adjustment to different spinning conditions.
Durch einfachen Austausch des Ringes ist die Länge und Form des Fasereinlaufs in Umfangsrichtung des Rings variierbar. Durch einen muldenförmigen Fasereinlauf kann der Einlaufbereich schon wesentlich vor dem Faserleitkanal erfolgen. Durch den Austausch des Ringes ist auch die Größe der Öffnung des Einsatzes zur Einstellung der Schmutzabscheideöffnung variierbar. Erfindungsgemäß ist der Ringspalt zwischen Auflösewalze und Einsatz durch Austausch des Ringes variierbar. Dazu können Einsätze mit unterschiedlichen Innendurchmessern des Innenhohlraums des Einsatzes verwendet werden.The length and shape of the fiber inlet in the circumferential direction of the ring can be varied by simply exchanging the ring. With a trough-shaped fiber inlet, the inlet area can take place substantially in front of the fiber guide channel. By exchanging the ring, the size of the opening of the insert for adjusting the dirt separating opening can also be varied. According to the invention, the annular gap between the opening roller and the insert can be varied by exchanging the ring. Inserts with different inside diameters of the inner cavity of the insert can be used for this.
Es kann für unterschiedliche Fasern und Anwendungen der entsprechend optimale Ring eingesetzt werden. Die Ringe erlauben einen unterschiedlichen Fasereinlaufbereich des Faserleitkanals. Ein weiterer Vorteil besteht darin, die Schmutzabscheideöffnung mehr oder weniger zu schließen bzw. zu öffnen. Auch kann der Ringspalt zwischen Auflösewalze und Ring im Bedarfsfall variiert werden.The corresponding optimal ring can be used for different fibers and applications. The rings allow a different fiber inlet area of the fiber guide channel. Another advantage is to close or open the dirt separation opening more or less. The annular gap between the opening roller and the ring can also be varied if necessary.
Der erfindungsgemäße Einsatz ist insbesondere dazu geeignet, durch einfaches Wechseln des Rings anwendungsspezifisch den passenden Faserleitkanal-Einlaufbereich zu wählen und/oder den Schmutzabscheidebereich so zu beeinflussen, dass der Anwender entscheiden kann, wie ausgereinigt sein Garn sein soll.The use according to the invention is particularly suitable for simply selecting the appropriate fiber guide channel inlet area by simply changing the ring and / or influencing the dirt separation area in such a way that the user can decide how clean his yarn should be.
Der erfindungsgemäße Einsatz ist vorzugsweise einteilig ausgebildet. Hierdurch ist eine einfache Herstellung und Montage ermöglicht.The insert according to the invention is preferably formed in one piece. This enables simple manufacture and assembly.
Nach einer vorteilhaften Ausführung bildet der Einsatz die Umgrenzung der Zuführöffnung und/oder der Schmutzabscheideöffnung an wenigstens drei Seiten.According to an advantageous embodiment, the insert forms the boundary of the feed opening and / or the dirt separating opening on at least three sides.
Nach einer weiteren vorteilhaften Ausgestaltung bildet der Einsatz die Umgrenzung der Abfuhröffnung.According to a further advantageous embodiment, the insert forms the boundary of the discharge opening.
Entsprechend einer noch weiteren Ausbildung der Erfindung ist der Einsatz koaxial zur Auflösewalze angeordnet. Bevorzugt ist der Einsatz koaxial zur Umfangswand angeordnet.According to yet another embodiment of the invention, the insert is arranged coaxially with the opening roller. The insert is preferably arranged coaxially to the peripheral wall.
Bevorzugt weist der Einsatz eine umlaufende Stufe auf, die mit der Abdeckung eine Labyrinthdichtung bildet.The insert preferably has a circumferential step which forms a labyrinth seal with the cover.
Der Einsatz schützt das Gehäuse vor Verschleiß. Vorzugsweise ist der Einsatz verschleißgeschützt, um eine lange Lebensdauer zu gewährleisten. Der Einsatz kann bei Verschleiß aber auch leicht und kostengünstig ausgetauscht werden.The insert protects the housing from wear. The insert is preferably protected against wear in order to ensure a long service life. The insert can also be replaced easily and inexpensively in the event of wear.

Eine Speisewalze 22, die sich in Pfeilrichtung A dreht, zieht ein Faserband durch eine Verdichter 33 über eine bewegliche Speisemulde 34 in die Zuführöffnung 27 des Auflösewalzengehäuses 17 ein. Die Speisemulde 34 ist um einen Zapfen 35 an der Gehäusewandung drehbar gelagert. Die Speisemulde 34 wird von einer Feder 36 abgestützt und gegen die Speisewalze 22 gedrückt.

In dem Auflösewalzengehäuse 17 dreht sich eine Auflösewalze 21 in Teilrichtung B um ihre Achse, die in dem Auflösewalzengehäuse 17 gelagert ist. Die Auflösewalze 21 trägt auf ihrem Umfang eine (nicht dargestellte) Auflösegarnitur, die im vorliegenden Fall sägezahnartig ausgebildet ist.

Aufgrund der in dem Auflösewalzengehäuse 17 herrschenden Luftströmung werden die einzelnen Fasern mit dem Luftstrom mitgenommen und durch den Faserleitkanal 14 dem Spinnaggregat zugeführt. Der aus dem Strom der vereinzelten Fasern ausgeschiedene Schmutz weist in der Regel eine größere Masse auf als die Fasern und wird deshalb im Wesentlichen tangential aus der Schmutzabscheideöffnung 28 herausgeschleudert.
