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 drivable 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.
  • the shaft of the spinning rotors in each case penetrates the rear wall of the rotor housing and is held on the rear side of the rotor housing in a bearing.
  • the spinning rotors of this spinning machine are driven by means of a central drive, which is arranged at one of the two front ends of the spinning machine and drives the individual spinning rotors via a machine-tangential belt.
  • the tangential belt, the bearings and the shafts of the spinning rotors are housed in a running in the longitudinal direction of the spinning machine channel.
  • an air supply duct is provided between the duct and the rotor housings, via which ambient air can be sucked into the duct containing the bearing.
  • 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 under pressure in operation rotor housing is with a removable Cover closed 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 open-end spinning device has a drive housing in which the rotor shaft of the spinning rotor extends.
  • the storage and the drive are arranged in the drive housing largely separated from the rotor housing, on the one hand to keep the volume of the rotor housing to be acted upon by spinning vacuum 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 but no complete sealing of the rotor housing to the drive housing is 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. This will be the Suction of impurities when opening the rotor housing avoided.
  • the drive housing with a filter provided with an opening through which the drive housing ambient air is supplied. Due to the annular gap between the rotor housing and the drive housing negative pressure prevails in the drive housing, so that an air flow from the environment is generated by the drive housing in the rotor housing, which prevents the accumulation of contaminants behind the rotor cup.
  • the drive housing has a third opening, via which it can be acted upon by the compressed air when the spinning device is stationary.
  • the object of the present invention is to propose an open-end spinning device in which, at least when the rotor housing is opened, the suction of contaminants into the drive housing is avoided and which can be used with different types of bearings.
  • 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 on. Furthermore, the open-end spinning device has 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 during the spinning operation via a vacuum channel of the spinning station with a spinning vacuum, 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 envisaged that the rotor housing and the drive housing spaced apart in an axial direction of the rotor shaft in the open-end spinning device.

  • 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.

  • the rotor shaft of the spinning rotor extends in a drive housing, in which also the individual drive and the bearing of the spinning rotor are arranged.
  • an air flow from the rotor housing is avoided in the drive housing, characterized in that the rotor housing and the drive housing in a Axial direction of the rotor shaft spaced from each other in the open-end spinning device are arranged.
  • 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.
  • 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 sealed by means of a seal 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 seal 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, as this can support the formation of an air flow from the drive housing into 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 other ways.
  • the bearing includes a magnetic bearing, in particular a radial magnetic bearing.
  • the execution of the radial bearing of the 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 stands on the third opening directly to the vacuum channel of the open-end spinning device for the spinning vacuum in combination.
  • 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 may 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.
  • the ambient air pressure avoided in the intermediate chamber due to the ambient air pressure avoided in the intermediate chamber, the emergence of a negative pressure in the drive housing during the spinning operation. 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.
  • 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 both at one with Negative pressure as well as at an acted upon by ambient air pressure intermediate chamber not only the suction of air and dirt in the drive housing when opening the rotor housing can be avoided, but it is also avoided during the spinning operation, the ingress of dirt into 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.

It is thus constructed during the spinning operation no negative pressure in the drive housing 17, so that too when opening the rotor housing 15 no dirt can be sucked into the drive housing 17. It is advantageous if the two housings 15 and 17 by a distance of at least 3 mm, preferably at least 5 mm, more preferably at least 10 mm to each other to avoid the effects of prevailing in the rotor housing 15 negative pressure on the drive housing 17 safely.
