Definitions
- Spinning device Spinning device, rotor spinning machine and method for preventing fiber build-up in a spinning device
- the invention relates to a spinning device for producing a yarn from a fiber material, a rotor spinning machine with at least one spinning device, and a method for preventing fiber accumulations within a rotor housing of a spinning device.
- spinning devices are known from the prior art and are used to produce a yarn from a fibrous material.
- individual textile fibers are typically fed to a spinning rotor rotating at high speed in spinning operation in several spinning devices formed as spinning boxes and spun into a yarn there, which is then withdrawn from the spinning rotor by means of a vacuum.
- the spinning device has a rotor housing within which the spinning rotor is arranged.
- a rotor housing cover is typically provided for opening and closing the rotor housing.
- Fiber material or the fiber ring can get into an area behind the spinning rotor and there soil the bearing of the spinning rotor or become entangled there, which typically leads to a failure of the rotor spinning machine after a short time.
- This problem occurs in all spinning devices of a rotor spinning machine.
- this is particularly problematic in the case of spinning devices with an individual drive for the spinning rotor and/or with a contact-free magnetic bearing, since the penetration of fiber material or even a fiber ring into the bearing air gap or entanglement with the spinning rotor axis immediately leads to a failure of the spinning device when the rotor is accelerated again Spinning rotor leads.
- the publication DE 10 2015 016 594 A1 already proposes to deactivate the negative pressure when braking the spinning rotor, initially at a speed of rotation of the spinning rotor at which a fiber ring is still held in the spinning rotor, and to close the spinning rotor by at least partially opening the rotor housing pivot so that if the spinning rotor brakes further, the fiber ring can fall out of the rotor groove of the spinning rotor. The vacuum is then activated again to suck off the fiber ring that has fallen out of the spinning rotor as well as the fiber material.
- this solution of the prior art has the disadvantage that for a period of time the speed of the spinning rotor is no longer sufficient to keep the fiber ring in the spinning rotor, but on the other hand the vacuum has not yet been activated again, so that it is not completely ensured that the fiber ring cannot get into the area behind the spinning rotor.
- the weight of the fiber ring fluctuates and the position of the fiber ring that has fallen out of the spinning rotor also varies, so that a sufficient volume flow cannot always be generated by means of the vacuum to reliably remove the fiber ring and the fiber material from the spinning device.
- the invention is therefore based on the object of providing a spinning device, a rotor spinning machine and a method which enable particularly reliable and trouble-free operation regardless of the number of interruptions in the spinning operation.
- the invention further relates to a rotor spinning machine with at least one spinning device according to the invention and preferably a plurality of spinning devices according to the invention, particularly preferably identical to one another.
- the method according to the invention for preventing fiber accumulations inside a rotor housing of a spinning device with a spinning rotor arranged inside the rotor housing and rotating at high speed during spinning and a rotor housing cover arranged on the rotor housing for opening and closing the rotor housing has as a method step that before opening the rotor housing and /or when the rotating spinning rotor is braked, in particular for the subsequent opening of the rotor housing, a flow of sealing gas is directed to an area of the rotor housing behind the spinning rotor or to the area of a spinning rotor rear or spinning rotor rear wall in order to prevent fiber material and/or a fiber ring behind the spinning rotor.

- the blow channels are preferably arranged on an inner wall of the rotor housing and/or on an area of the rotor housing covered by the spinning rotor in relation to the opening of the rotor housing or in relation to the rotor housing cover.

- an embodiment of the method for preventing fiber accumulations within a rotor housing of a spinning device in which the blocking gas flow is deactivated during the spinning process for producing a yarn from a fiber material by means of the spinning rotor and/or the blocking gas flow when braking the spinning rotor is dependent the rotor speed, preferably when the rotor speed falls below 50,000 rpm, particularly preferably 30,000 rpm and very particularly preferably 20,000 rpm, is activated, since from a corresponding number of revolutions the fiber material is no longer sufficiently held in a fiber ring of the spinning rotor and thus can get behind the spinning rotor or to the back of the spinning rotor.

However, if the spinning rotor 2 falls below a speed that is typically in the range between 50,000 rpm and 20,000 rpm, the centrifugal forces are no longer sufficient to hold the fiber material located in the spinning rotor 2 in it, so that a fiber accumulation, in particular a fiber ring, can get from the spinning rotor 2 into the interior of the rotor housing 1 .
- a device 3 for generating a sealing gas flow is arranged in the area of the rotor housing 1 behind the spinning rotor 2 (see Fig. 1), by means of which several sealing gas flows can be directed to an area behind the spinning rotor when the spinning rotor 2 is braked, so that no fiber ring and no fiber accumulations can get into this protected area.

- blower channels 5 To supply the individual blower channels 5 with compressed air, they are connected inside the wall of the rotor housing 1 to an annular air distributor 6 which is supplied via a compressed air connection 7 arranged on the outside of the rotor housing 1 . All of the blower channels 5 and in particular all of the openings of the blower channels 5 for the exit of sealing gas are formed identically to one another and/or have a round cross section.
