Definitions

  • the present invention relates to a method for operating an open-end rotor spinning device and an open-end rotor spinning machine with a plurality of open-end rotor spinning devices arranged next to one another.
  • Open-end rotor spinning machines have a large number of work stations arranged next to one another.
  • An open-end rotor spinning device is arranged at each of the work stations.
  • An open-end rotor spinning device comprises a rotor housing with a cover element for closing the rotor housing.
  • a spinning rotor is arranged in the rotor housing.
  • the spinning rotor is rotatably mounted.
  • the spinning rotor can be driven in various ways for spinning. It is known to drive the spinning rotors of several open-end rotor spinning devices via a common drive. The force can be transmitted from the common drive to the spinning rotors, for example by means of a belt. It is also known that an individual electromotive drive is assigned to each spinning rotor. In connection with an individual drive, the spinning rotor is preferably supported without contact.
  • a contactless mounting can be designed as a magnetic mounting. Contactlessly mounted spinning rotors with individual drives are particularly sensitive to contamination.
  • a negative pressure is required in the rotor housing for spinning. Therefore, known open-end rotor spinning machines have a central vacuum source and a machine-long vacuum line. The vacuum supply to the open-end rotor spinning devices is implemented by connecting the rotor housing to the machine-length vacuum line.
  • fiber material is introduced into the rotor housing via a fiber guide channel and the finished spun thread is withdrawn from the rotor housing via a thread take-off channel.
  • the end of the thread take-off channel on the spinning rotor side is located on an approach which is attached to the cover element and protrudes into the spinning rotor.
  • the DE 10 2004 016 547 B4 discloses a method of cleaning a spinning rotor.
  • the cleaning is already carried out on the spinning rotor which is still turning or running out.
  • the cover element of the rotor housing is automatically opened by means of a movable maintenance device device and a cleaning device is fed to the spinning rotor, whereby the speed of the spinning rotor has not yet fallen below a minimum.
  • fiber rings collect, which are held in the rotor groove by the centrifugal forces.
  • the cleaning device should intervene before a fiber ring is released from the rotor groove.
  • Such a cleaning device can, for example, seal the outer annular space surrounding the spinning rotor and thus prevent the fibers from escaping.
  • the method is intended to prevent fibers from wrapping themselves around the attachment with the thread take-off channel and being pulled out of the spinning rotor when the cover element is opened.
  • the cover of the vacuum chamber should only be moved a small distance away from the vacuum chamber before the open-end spinning rotor comes to a standstill and then the vacuum chamber again briefly getting closed. In this way, a fiber ring present in the interior of the rotor can be removed more easily before the actual cleaning.
  • a housing with a spinning rotor is known, which is connected to a vacuum line, wherein a valve is located in the vacuum line to bring the spinning vacuum into or out of action as required.
  • a valve is located in the vacuum line to bring the spinning vacuum into or out of action as required.
  • a method for operating an open-end rotor spinning device For spinning, a rotor housing is closed with a cover element and subjected to negative pressure by means of a negative pressure supply, a spinning rotor rotates in the rotor housing and an attachment attached to the cover element protrudes into the spinning rotor with a thread take-off channel.
  • the method according to the invention starts with this finding. Accordingly, the negative pressure in the rotor housing should be eliminated before the centrifugal forces no longer hold a fiber ring located in the rotor groove in the rotor groove. By releasing the negative pressure, the air flow described above is prevented. A fiber ring that has collapsed due to the decreasing centrifugal forces thus remains in the interior of the spinning rotor. In contrast to what is described in the prior art, it is therefore not necessary for a cleaning device to intervene as quickly as possible. Rather, the fibers located in the interior of the spinning rotor can later be sucked off in a simple manner by moving the cover element when the negative pressure is restored. The method according to the invention therefore does not require any additional cleaning device. The cover element can be moved by an adjusting device at the work site.
  • the cover element When the cover element is moved between an open position and a closed position, the cover element passes through a position in which the cover element is opened so far that there is sufficient space between the attachment and the spinning rotor, and the cover element is closed so far that a sufficient There is negative pressure in the rotor housing in order to suck off the fibers.
  • the displacement of the cover element can take place when the spinning rotor is still rotating or when the spinning rotor is already at a standstill. It is only important that the speed falls below the second speed at which the fiber ring has already collapsed. Otherwise the shift would be counterproductive and would do exactly what the present invention is intended to prevent, namely that fibers wrap around the attachment.
  • One possibility is to move the cover element into the open position. Even if the vacuum supply continues to suck air out of the rotor housing, the air is immediately replenished via the opening, so that there is no vacuum in the rotor housing.
  • the vacuum supply of the open-end rotor spinning device is switched on.
  • the cover element initially also remains closed.
  • Switching off the vacuum supply has the advantage that a vacuum source of the open-end rotor spinning machine is less stressed and energy is saved.
  • the energy consumption of the vacuum source is significantly higher with an open rotor housing than with a closed rotor housing.
  • the cover element is transferred from the open position to the closed position for suction of the collapsed fiber ring below the second speed with an effective vacuum supply.
  • This process step can be carried out independently of the previous history. If the removal of the negative pressure in the rotor housing was achieved by opening the cover element without the negative pressure supply having been switched off, the negative pressure supply is effective and the cover element can be transferred directly into the closed position. If the negative pressure has been eliminated by switching off the negative pressure supply, the cover element can be opened at some point. As long as the vacuum supply is switched off, opening the cover element has no effect. Before closing the cover element, however, the vacuum supply must be switched on again so that the fiber ring that has collapsed is also sucked off when it is closed.
  • the collapsed fiber ring can also be suctioned off by moving the cover element from the closed position to the open position below the second speed with an effective vacuum supply.
  • an effective vacuum supply Such a procedure is particularly advisable if, according to the invention, the cancellation of the negative pressure was achieved by switching off the negative pressure supply.
  • the vacuum supply must then be switched on again before opening, preferably with the spinning rotor at a standstill.
  • the object is also achieved by an open-end rotor spinning machine for carrying out the method according to the invention with a large number of open-end rotor spinning devices arranged next to one another.
  • the open-end rotor spinning devices each have a rotor housing, a spinning rotor arranged in the rotor housing, a cover element for closing the rotor housing, which can be displaced between an open position and a closed position, an adjusting device for displacing the cover element between the open position and the closed position, and one on the cover element attached approach with a thread take-off channel that protrudes into the spinning rotor in the closed position, and a vacuum supply for applying vacuum to the rotor housing.
  • a control device is designed to control one or more open-end rotor spinning devices when the spinning rotor is braked in such a way that the negative pressure in the rotor housing above a first speed at which the centrifugal forces still hold a fiber ring in the rotor groove of the spinning rotor is canceled becomes. Furthermore, the control device is designed to control one or more open-end rotor spinning devices in such a way that the fiber ring by moving the cover element between the open position and the closed position below a second speed at which the fiber ring has already collapsed due to the decreasing centrifugal forces due to the Rotor housing restored negative pressure is sucked off.
  • the control device is designed to close the valve for switching off the vacuum supply above the first speed.
  • control device is designed to control the actuating device in such a way that the cover element is transferred from the open position to the closed position below the second speed with an effective vacuum supply.
  • the control device can furthermore be designed to control the actuating device in such a way that the cover element is transferred from the closed position to the open position below the second speed with an effective vacuum supply.

  • Fig. 1 As can be seen, the rotor housing 2, which is open to the front, is closed during the spinning operation by a pivotably mounted cover element 8 into which a channel plate (not shown in detail) with a seal 9 is embedded.
  • 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 during the spinning process.
  • the vacuum line 10 forms the vacuum supply to the open-end rotor spinning device 1.
  • the vacuum source 11 also supplies the remaining open-end rotor spinning devices of the open-end rotor spinning machine.
  • the vacuum line 10 has a valve 31.
  • a projection 12 is arranged, which has the rotor-side end 13 of the thread take-off channel 15 and the opening area of the fiber guide channel 14.
  • an opening roller housing 17 is fixed on the cover element 8, which is mounted so as to be rotatable to a limited extent about a pivot axis 16.
