Definitions
- the present invention relates to an open-end spinning device of a rotor spinning machine with a spinning rotor, which has a rotor cup, in which a fiber material is spinnable, and a rotor shaft, via which the spinning rotor is driven and preferably stored without contact in a storage. Furthermore, the open-end spinning device has a drive for driving the spinning rotor, and a rotor housing, in which the rotor cup of the spinning rotor is arranged and which is acted upon during the spinning operation via a vacuum channel of the spinning station with a spinning vacuum. In addition, the open-end spinning device has a drive housing, in which the rotor shaft of the spinning rotor extends and in which the drive and the bearing of the spinning rotor are arranged.
- contactless bearings such as magnetic bearings and air bearings have become known in addition to the storage in a wedge gap of support discs.
- Such mounted rotors are usually driven by an electric motor single drive.
- the rotor housing which is under vacuum during operation, is closed with a removable cover to allow access to the rotor housing in certain situations. For example, it is necessary in an interruption of the spinning process by yarn break or a cleaning step to open the rotor housing to perform various maintenance activities. It also happens that the rotor housing is opened even during ongoing operation of operating personnel.
- the storage and the drive are arranged in a largely separated from the rotor housing drive housing, on the one hand to keep the volume of the spinning vacuum to be acted upon rotor housing as small as possible and on the other hand to protect the drive and storage of the spinning rotor from contamination by dust and fly. Due to the spinning at very high speeds spinning rotor is not complete Sealing of the rotor housing to the drive housing possible, so that builds up a negative pressure in the drive housing during spinning operation.
- the EP 1 156 142 B1 shows, for example, an open-end spinning device with such a single driven and magnetically mounted spinning rotor.
- the EP 2 069 562 A1 proposes, therefore, to provide the drive housing with an additional air inlet and to supply compressed air to the drive housing before opening the rotor housing in order to perform pressure equalization there before opening the rotor housing. As a result, the suction of impurities when opening the rotor housing is avoided.
- the object of the present invention is to propose an open-end spinning apparatus in which, at least when opening the rotor housing, the suction of contaminants into the drive housing is avoided and which can be used with different types of storage.
- An open-end spinning device of a rotor spinning machine has a spinning rotor with a rotor cup, in which a fiber material is spinnable, and with a rotor shaft, via which the spinning rotor is drivable and is preferably mounted without contact in a bearing.
- the open-end spinning device a drive, in particular a single drive, for driving the spinning rotor, a rotor housing, in which the rotor cup of the spinning rotor is arranged and which is acted upon by a spinning pressure of the spinning station with a spinning vacuum during spinning operation, and a drive housing, in which the rotor shaft of the spinning rotor extends and in which the drive and the storage of the spinning rotor are arranged on. It is provided that the rotor housing and the drive housing are arranged in an axial direction of the rotor shaft spaced from each other in the open-end spinning device.
- a front and a rear boundary wall are formed by a front and a rear boundary wall and either a circumferential side wall (for example, in the case of a cylindrical housing) or a plurality of individual side walls.
- the front boundary wall is in each case facing the withdrawal side of the spinning device and, in the case of the rotor housing, is formed by a removable cover, on which, as a rule, the draw-off nozzle of the spinning device is arranged.
- the rear boundary wall however, in each case faces the drive side of the spinning device.
- the rotor housing and / or the drive housing may also be connected to one another by a spacer, which ensures the spaced arrangement of the rotor housing and the drive housing to each other.
- a spacer can also be integrally formed on the rotor housing and / or the drive housing.
- a method for operating an open-end spinning device of a rotor spinning machine wherein the open-end spinning device by means of a drive, in particular a single drive, driven and in a storage preferably contact-free mounted spinning rotor having a rotor cup and having a rotor shaft, and in which the rotor cup of the spinning rotor is arranged in a rotor housing, the rotor housing is subjected to spinning vacuum during the spinning operation.
- the rotor shaft of the spinning rotor extends in a drive housing, in which also the drive and the storage of the spinning rotor are arranged.
- an air flow from the rotor housing into the drive housing is avoided by arranging the rotor housing and the drive housing in an axial direction of the rotor shaft spaced from one another in the open-end spinning device.
- an intermediate chamber is arranged between the rotor housing and the drive housing, wherein the intermediate chamber has a first connection opening to the rotor housing and a second connection opening to the drive housing. Furthermore, the intermediate chamber has a third opening, via which the intermediate chamber communicates either with a negative pressure source or with ambient air pressure at least when the spinning operation is interrupted.
- an intermediate chamber is arranged between the rotor housing and the drive housing, which communicates with the rotor housing via a first connection opening and with the drive housing via a second connection opening stands.
- the shaft of the spinning rotor extends from the rotor housing into the drive housing.
- the intermediate chamber is subjected to negative pressure or ambient air pressure, at least when the spinning operation is interrupted, such that an air flow into the drive housing is at least avoided when the rotor housing is opened.
- an air flow from the drive housing is generated in the intermediate chamber.
- the intermediate chamber is thus at least at the same time with the beginning of the opening of the rotor housing, but preferably already applied shortly before either with negative pressure or ambient air pressure.
- the intermediate chamber remains at least as long as the interruption of the spinning process continues or as long as the rotor housing is open.
- the arranged between the rotor housing and the drive housing intermediate chamber to prevent or at least largely avoided by the targeted pressurization of the intermediate chamber, an air flow and the associated suction of polluted air in the drive housing.
- by applying the intermediate chamber with negative pressure can also be a targeted air flow generated by the intermediate chamber, which counteracts not only when opening the rotor housing a suction of dirt particles in the drive housing, but can also avoid deposits during operation.
- the intermediate chamber can be designed both as a separate housing or be formed by an extension of the rotor housing or the drive housing or both housing.
- the side wall or the side walls of the rotor housing may be extended beyond its rear boundary wall and thereby form the intermediate chamber.
- the thus formed intermediate chamber is by means of a seal sealed against the adjacent drive housing.
- the side wall or the side walls of the drive housing could be extended to beyond the front boundary wall also.
- the first and / or the second connection opening are preferably arranged around the rotor shaft.
- the first and / or the second connection opening are formed as an annular gap around the rotor shaft, since a complete sealing of the housing to each other is usually not possible.
- the first connection opening can thus also be designed as an annular gap around the rotor cup assembly.
- a certain sealing of the housing or the intermediate chamber relative to each other can be achieved, which in particular makes it possible to maintain the spinning negative pressure in the rotor housing, and nevertheless a targeted air flow is formed through the annular gaps, which dissipates soiling.
- the first connection opening is provided in the region of the collar of the rotor cup, then, at least in the case of an intermediate chamber subjected to negative pressure, any possible contamination from the coupling point between rotor shaft and rotor cup can be sucked off during the disassembly of the rotor cup.
- the bearing includes an axial bearing acting on the end of the spinning rotor facing away from the rotor cup. This takes over the axial bearing of the spinning rotor, so that the radial bearing of the spinning rotor can be formed independently of this.
- the design and control of the radial bearing is thereby compared to a design in which no separate thrust bearing is provided, simplified and the storage is less prone.
- the axial bearing is designed as an axial air bearing or at least includes an axial air bearing, since this results in the formation an air flow from the drive housing can be supported in the intermediate chamber.
- the invention can also be used in an open-end spinning device, in which the axial bearing of the spinning rotor is designed as a magnetic bearing or in another way.
- the bearing includes a magnetic bearing, in particular a radial magnetic bearing.
- a magnetic bearing in particular a radial magnetic bearing.
- the embodiment of the radial bearing of the open-end spinning rotor is advantageous as a magnetic bearing. Since such magnetic bearings are particularly susceptible to contamination, the benefits of the formation of a targeted air flow using an intermediate chamber between the rotor housing and the drive housing there are particularly significant.
- the intermediate chamber is at least when opening the rotor housing, but preferably already applied before opening the rotor housing with negative pressure.
- the intermediate chamber has, in addition to the two connecting openings designed as an annular gap, a third opening which is in communication with a vacuum source.
- the intermediate chamber is constantly subjected to negative pressure, that is to say also during the spinning operation, since the deposition and migration of contaminants can already be avoided during the spinning operation.
- the intermediate chamber as well as the rotor housing is subjected to spinning negative pressure.
- the intermediate chamber is connected via the third opening directly to the vacuum channel of the open-end spinning device for the spinning vacuum.
- the intermediate chamber can be in communication with the vacuum channel, which also connects the rotor housing with the vacuum source or a machine-long vacuum line, or have its own vacuum channel to the vacuum source or to the machine-long vacuum line.
- the third opening of the intermediate chamber can be provided in this case with a controllable shut-off device, which is preferably actuated by the opening and closing of the rotor housing.
- a controllable shut-off device which is preferably actuated by the opening and closing of the rotor housing.
- the opening of the rotor housing or a pivot housing connected to the rotor housing can be registered by a sensor, which in turn triggers the switching of the obturator.
- a purely mechanical coupling of the obturator with the rotor housing is of course also possible.
- the third opening is not connected to a vacuum source, but communicates only with the ambient air.
- the intermediate chamber is constantly acted upon by the third opening with ambient air pressure or is in communication with ambient pressure. In this case, the generation of a negative pressure in the drive housing during spinning operation is avoided due to the ambient air pressure in the intermediate chamber. Therefore, no air is sucked into the drive housing even when the rotor housing is opened.
- This embodiment of the invention can be used both with a magnetic bearing and with an air bearing or with a combined storage. It is also possible to metered via the third opening of the intermediate chamber supply only a small amount of air, which is barely sufficient to prevent the suction of dust from the rotor housing in the intermediate chamber or in the drive housing.
- this can also be supplied to the rotor housing a very small amount of air, which prevents deposits in the rotor housing behind the rotor cup from the outset. It can thus no longer get into the drive housing when opening the rotor housing and thereby taking place there pressure increase.
- the amount of air supplied can be controlled by the size of the third opening. It turns in this case in the intermediate chamber and due to the connection opening to the drive housing in the drive housing, a pressure that is higher than the spinning vacuum in the rotor housing, but still due to the low amount of air supplied below the ambient air pressure.
- the ambient air is filtered before it is fed into the intermediate chamber.
- the third opening is preferably provided with an air filter for this purpose.
- the bearing of the spinning rotor has an air bearing, it is advantageous for carrying out the method if the air flow through the air bearing is controlled in such a way that there is always a greater pressure in the drive housing than in the intermediate chamber. It can thereby be avoided both in a pressurized with ambient pressure and an intermediate chamber chamber not only the suction of air and dirt in the drive housing when opening the rotor housing, but it is also avoided during the spinning operation, the ingress of contaminants in the drive housing. Namely, such contamination can also occur during normal spinning operation without active suction of polluted air due to the imperfect seal in the region of the annular gaps.
- FIG. 1 shows a schematic representation of an open-end spinning device 1 of a rotor spinning machine 2 in a schematic side view.
- the rotor spinning machine 2 includes in a conventional manner a feed device 8, which the open-end spinning device 1, a fiber material 6 via a dissolving device 9, which dissolves the fiber material into individual fibers, supplies.
- the fiber material 6 in a rotor cup 4 spun a spinning rotor 3 to a yarn 7, withdrawn via a take-off device 10 and wound with a winding device 11 on a spool 12.
- the open-end spinning device 1 comprises in addition to the spinning rotor 3 with the rotor cup 4 and the rotor shaft 5 (see Figures 2 - 6 ), a rotor housing 15, in which the rotor cup 4 is arranged, and a drive housing 17, in which the shaft 5 of the spinning rotor 3 extends.
- the spinning rotor 3 is driven by the present illustration by means of a single drive 14 and stored in a bearing 13.
- the bearing 13 includes radial bearings 25 and may also include a separately formed from the radial bearings 25 thrust bearing 24.
- the thrust bearing 24 may be formed as axial air bearing 24a or as axial magnetic bearing or by a combination of these two Lagerungsart be formed. Also in the open-end spinning apparatuses 1 of the following Figures 2 - 6 Deviating from the types of storage shown in each case, another type of storage can alternatively or additionally be used. For reasons of clarity, in the present case only the bearing 13 is labeled without its individual components.
- the rotor housing 15 is closed by means of a removable, in particular pivotable, cover 27 (see arrow).
- the lid 27 of the rotor housing 15 can be removed by both an automatic maintenance device and an operator, as symbolized by the arrow herein.
- the cover 27 of the rotor housing 15 is connected to a swing-pivot housing 29, and can be opened together with this.
- the rotor housing 15 is acted upon via a vacuum channel 16 of the open-end spinning device 1 with a spinning negative pressure p SU required for the spinning process.
- the vacuum channel 16 of the open-end spinning device 1 is connected to a machine-length vacuum line 33, which in turn communicates with a central vacuum source 23.
- a seal 28 is arranged between the cover 27 of the rotor housing 15 and the rotor housing 15.
- the Rotor shaft 5 of the spinning rotor 3 thus extends from the rotor housing 15 into the drive housing 17.
- an intermediate chamber 18 is provided between the rotor housing 15 and the drive housing 17 spaced therefrom.
- Such open-end spinning device 1 with the rotor housing 15 and the drive housing 17 will be described below with reference to FIG Figures 2 - 6 described in more detail, showing a detailed representation of an open-end spinning device 1 in various embodiments.
- FIG. 2 in turn, the rotor 3 with the rotor cup 4 and the rotor shaft 5 can be seen. Furthermore, a discharge nozzle 34 arranged in the cover 27 of the rotor housing 15 can be seen, via which the yarn 7 produced in the rotor cup 4 is drawn off.
- both the individual drive 14 and the mounting 13 can now be seen in detail.
- two radial bearings 25 are provided which are designed as magnetic bearings 25a.
- a thrust bearing 24 is provided which may include an axial magnetic bearing or an axial air bearing 24a or a thrust bearing 24 combined from both types of bearings.
- an axial air bearing 24a is shown, which is fed via a compressed air source 31 and acts on an end of the spinning rotor 3 facing away from the rotor cup 4.
- FIG. 2 removable, that in spite of the arrangement of ring seals 21 each have an annular gap between adjacent housings or chambers remains.
- an intermediate chamber 18 is therefore arranged between the rotor housing 15 and the drive housing 17.
- the intermediate chamber 18 is connected to the rotor housing via a connection opening 19 and via a second connection opening 20 to the drive housing 17.
- an annular seal 21 is provided in each case in the region of the two annular gaps.
- the intermediate chamber 18 now has a third opening 22 which is constantly in communication with a vacuum source 23.
- the intermediate chamber 18 can be connected via the machine-length vacuum line 33 to the vacuum source 23 for the spinning vacuum p SU .
- the intermediate chamber 18 is also connected to the vacuum channel 16 for this purpose.
- the spinning vacuum p SU prevails in the rotor housing 15, while due to the axial bearing 24 designed as air bearing 24 a, a pressure P MG which is greater than the spinning vacuum p SU is established in the drive housing 17. Due to the very low air flow through the air bearing 24a compared to the air flow through the vacuum channel 16, however, the air pressure P MG is always below the spinning device 1 surrounding ambient air pressure P U also during spinning operation. Due to this, an air pressure P ZK sets in the intermediate chamber 18, which is also below the ambient air pressure P U and between the spinning vacuum P SU and the air pressure of the drive housing P AG . It is thus generated during the spinning operation, an air flow from the drive housing into the intermediate chamber, which prevents the penetration of contaminants into the drive housing 17 advantageously already during the spinning operation.
- the described effect can be improved even if similar to the FIG. 3 the intermediate chamber 18 is connected via a separate vacuum channel 16a to the machine-length vacuum line 33 or another vacuum source 23. Due to the sudden pressure equalization in the rotor housing 15 to the ambient air pressure P U when opening the rotor housing 15, pressure equalization may also occur in the vacuum duct 16, so that the intermediate chamber 18 can no longer be sufficiently pressurized with negative pressure. Through a connection of Intermediate chamber 18 by means of its own vacuum channel 16a, the negative pressure (air pressure P ZK ) in the intermediate chamber 18 even after opening the rotor housing 15 can still be maintained.
- the third opening 22 or the connection of the intermediate chamber 18 to the vacuum channel 16 close to the machine-length vacuum line 33 or to connect the intermediate chamber 18 directly to the machine-length vacuum line 33. In this area, due to the proximity to the machine-length vacuum line 33, even when opening the rotor housing 15 there is still a sufficient negative pressure.
- FIG. 3 shows a modification of the open-end spinning device of FIG. 2 , It is therefore referred to below only to the differences from the device FIG. 2 received; the same elements and functions are no longer described separately.
- the intermediate chamber 18 is connected via a third opening 22 to a vacuum source 23.
- the intermediate chamber 18 is also connected via its own vacuum channel 16a with the vacuum source 23.
- the intermediate chamber 18 could be connected directly to the machine-length vacuum line 33.
- the third opening 22 is provided with a controllable obturator 26, so that the intermediate chamber 18 is not constantly in communication with the vacuum source 23, but only when opening the lid 27. Due to the connection openings 19 and 20 to the pressurized with spinning vacuum P SU rotor housing However, during the spinning operation, a negative pressure also occurs in the intermediate chamber 18 and in the drive housing 17. According to the present illustration, a sensor 32 is provided for this purpose either in the region of the cover 27 of the rotor housing 15 or in the region of the pivot housing 29, which sensor the opening of the rotor housing 15 is registered thereby the obturator 26 opens.
- the intermediate chamber 18 is thus further subjected to a negative pressure during opening of the cover 27 of the rotor housing 15, which prevents the suction of dirt into the drive housing 17. Any deposits from the area of the rotor housing 15 are also removed via the third opening 22 and the vacuum channel 16a after opening the obturator 26.
- the intermediate chamber 18 is acted upon in each case with spinning vacuum P SU when opening the rotor housing 15, any impurities are sucked out of the rotor housing 15 via the vacuum channel 16a and no longer reach into the drive housing 17.
- the penetration of impurities in the Drive housing 17 can thus be avoided in all types of storage.
- the thrust bearing 24 is formed as Axialluftlager 24a or storage includes an air bearing. In this case prevails in the drive housing 17 is always a higher air pressure P AG than the air pressure P ZK in the intermediate chamber 18, which in turn the suction of impurities is avoided.
- FIG. 4 shows a further modification of in FIG. 2 Open-end spinning device 1 shown with a vacuum-pressurized intermediate chamber 18, in which the intermediate chamber 18 communicates via the third opening 22 with the vacuum channel 16 of the rotor housing 15 in connection.
- a separate vacuum channel 16a instead of a separate vacuum channel 16a, it can also be provided to close it against the vacuum channel 16 when the rotor housing 15 is opened.
- the rotor housing 15 is for this purpose provided with a shut-off device 26 which blocks or releases its connection to the vacuum channel 16.
- a purely mechanical coupling may be provided with the lid 27 of the rotor housing or it may be similar to in FIG. 3 shown a sensor-controlled control done.
- a slide 26 a is provided as a shut-off device 26, which alternately connects the rotor housing 15 and the intermediate chamber 18 to the vacuum passage 16.
- the rotor housing 15 is connected to the vacuum channel 16, so that in the rotor housing 15 in the usual way, the spinning vacuum p su is maintained.
- the intermediate chamber 18, however, is closed in the regular spinning operation against the vacuum channel 16. Due to the connection opening 19 to the rotor housing but a negative pressure is still built up in the intermediate chamber.
- the slider 26a is now controllable such that when opening the rotor housing 15, the connection of the rotor housing 15 is closed to the vacuum channel 16, while the third opening 22 is released and the intermediate chamber 18 is now in communication with the vacuum channel 16.
- a Druckan Eisen to the ambient air pressure P U thus takes place only in the open rotor housing 15, but not in the vacuum channel 16, while the intermediate chamber 18 is now also applied via the third opening 22 with negative pressure.
- FIG. 5 A further embodiment of an open-end spinning device 1 with a vacuum-loaded intermediate chamber 18, which can be used in particular for bearings without axial air bearing 24 a, is in FIG. 5 shown.
- the intermediate chamber 18, as in FIG. 3 described connected by means of its own vacuum channel 16a with a vacuum source 23.
- a shut-off device 26 it is also possible to provide only one vacuum channel 16 and shut off the rotor housing 15 when opening against the vacuum channel 16 by means of a shut-off device 26.
- the obturator 26 is to the comments too FIG. 3 directed.
- the drive housing 17 is provided with a flushing opening 35, via which the drive housing 17 temporarily, preferably when opening the rotor housing 15, dust-free purging air can be supplied to flush into the drive housing 17 possibly penetrated impurities in the intermediate chamber 18.
- the flushing port 35 is provided with a filter 30 and communicates with a filter 30 in connection.
- a flushing line 36 is connected to the flushing opening 35, which in turn is provided with a filter 30 and is closed during the spinning operation by the cover 27 of the rotor housing 15.
- the purge line 36 is then connected to the ambient air, so that the drive housing 15th dust-free purging air is supplied. Since the flushing takes place only when the rotor housing 15 is open, the flushing opening 35 can be relatively generously dimensioned, as a result of which rapid flushing can be achieved.
- FIG. 6 A further embodiment of an open-end spinning device 1, in which the penetration of contaminants into the drive housing 17 is avoided, is known in FIG. 6 shown. Unlike in the FIGS.
- the third opening 22 is provided with an air filter 30.
