Definitions

  • the invention relates to an open-end rotor spinning with a single motor driven spinning rotor, the rotor cup rotates in a garbuchbeetz Maschinenppe rotor housing, to which a drive for the spinning rotor and bearing arms for a Faserbandauflinate immunity exhibiting lid member are connected, and which has a part of a centering device, according to
  • the rotor housing which is open towards the front is closed by the cover element during the spinning process, which in turn has a receptacle for a replaceably arranged channel plate adapter.
  • Open-end rotor spinning devices have been significantly advanced over time, particularly as regards their production performance and the quality of yarns produced.
  • the rotational speeds of the spinning rotors have in the meantime been increased to well above 100,000 rpm, which was only possible by significantly reducing the spinning elements, in particular the spinning rotor.
  • the reduction of the spinning elements also meant that in the operating state between the spinning elements only relatively small gaps are given, which requires not only a very precise production of the spinning elements, but also an accurate positioning of these components.
  • the open-end rotor spinning devices must furthermore have good pneumatic properties. That is, the open-end rotor spinning devices must be designed so that during spinning operation in the open-end rotor spinning always a sufficiently high spinning vacuum is present, while preventing that false air can enter the open-end rotor spinning devices.
  • Some of the known patent applications relate, for example, the interchangeable positioning of a channel plate adapter in the cover element of an open-end rotor spinning device, wherein in particular a minimal false air-free arrangement of the channel plate adapter in a receptacle of the lid member value is placed.
  • the DE 43 34 485 A1 describes, for example, an open-end rotor spinning device with a vacuum-pressurizable rotor housing, in which rotates the rotor cup of a spinning rotor at high speed during spinning operation.
  • the rotor housing is closed during spinning by a pivotally mounted cover member having an annular groove for inserting a lip seal member and an open in the direction of the rotor housing, equipped with conical contact surfaces receptacle for a channel plate adapter.
  • the open-end spinning device is closed, the cover element rests against the rotor housing with the lip sealing element and seals it from the front.
  • the channel plate adapter is interchangeably determined by means of bolts which pass through corresponding through holes in the cover element.
  • a cylindrical pin is provided, which is embedded in a bore of the cover member and corresponds with a corresponding fitting bore on the back of the channel plate adapter.
  • a disadvantage of this known open-end spinning device is, inter alia, the somewhat cumbersome way of fastening the channel plate adapter. That is, in a lot change, in which, for example, all spinning rotors of an open-end rotor spinning machine and thus all channel plate adapter are replaced, always awkward at both of the numerous jobs of the textile machine, the two bolts must be unscrewed, which is relatively time consuming and has a very adverse effect on the efficiency of the textile machine.
  • the in the DE 43 34 485 A1 described embodiment of an open-end rotor spinning device could therefore not prevail in practice.
  • Open-end rotor spinning device described has a pivotally mounted lid member for closing the rotor housing during the spinning operation, which in addition to the known lip seal member, as usual, has a receptacle for a channel plate adapter.
  • this known open-end rotor spinning device of the channel plate adapter is locked in the receptacle by means of a bar spring so that the channel plate adapter can be quickly and easily removed if necessary by bending back the bar spring. That is, the rod spring fixed to the cover element grasps for locking the channel plate adapter in a Tangentialnut, which is incorporated in the conical contact surface of the bearing body of the channel plate adapter.
  • the DE 196 17 527 A1 describes, for example, an open-end rotor spinning device, in which the channel plate adapter in the installed state is fixed both positively and positively in a receptacle of the cover element.
  • a non-positive fastening means a magnetic coupling is provided in this case, while the positive connection via a centrally arranged threaded connection.
  • the channel plate adapter is fixed purely magnetically in the associated receptacle of the cover element and, if necessary, that is, when it is to be replaced, are pressed out of the receptacle by means of a special mechanical punch.
  • the rear projection penetrates a corresponding hole in the receptacle of the lid member and is acted upon by a fastener arranged on the lid member so that the conical bearing body of the channel plate adapter is uniformly drawn into the receptacle of the lid member whose bearing surfaces are formed correspondingly conical.
  • the channel plate adapter has a forward facing circumferential sealing surface which rests with the open-end rotor spinning device to a corresponding sealing surface on the rotor housing.
  • the channel plate adapter is further equipped with laterally arranged attachment lugs, which correspond in the installed state of the channel plate adapter with an associated fastening means in the region of the receptacle of the lid member.
  • Such a design not only has the advantage that the channel plate adapter can be fixed exactly in the receptacle of the cover element due to the uniformly introduced pressure force, but also allows easy replacement of the channel plate adapter.
  • it is reliably ensured by the circumferential sealing surface of the channel plate adapter, that during the spinning operation, despite the negative pressure prevailing in the rotor housing, no false air can reach the region behind the channel plate adapter. That is, by the voltage applied to the rotor housing circumferential sealing surface the formation of harmful false air flows and thus the emergence of excessive contamination in the region of the cover element is reliably prevented.
  • the DE 27 21 386 A1 discloses an open-end spinning unit with a housed in a rotor housing spinning rotor, the shaft is mounted in a wedge-shaped gap formed by support roller pairs and is driven by a tangential.
  • an insert On the cover of the rotor housing, an insert is fixed, which projects into the spinning rotor.
  • On the rotor housing, a centering approach is attached, which penetrates into a corresponding profiling of the insert.
  • open-rotor spinning devices are known in which the rotor housing is designed as a central, supporting component. That is, in these open-end rotor spinning devices both a single-motor drive for the spinning rotor are screwed to the rotor housing, as well as bearing arms on which a lid member having a Faserbandaufleria observed limited rotatably and removably mounted.
  • the cover member also has a receptacle for a channel plate adapter.
  • the bearing arms and the rotor housing are preferably made as aluminum castings, while the cover member is at least partially made of plastic.
  • a special centering device is also provided between the rotor housing and cover element, which ensures when closing the rotor housing that the cover element in both the horizontal and in the vertical direction is positioned exactly.
  • Corresponding centering devices which are arranged in the area of the rotor housing / cover element and which are intended to ensure an alignment of the cover element with respect to the rotor housing when closing an open-end rotor spinning device, are also provided by FIGS DE 10 2006 019 224 A1 and / or the DE 10 2007 039 868 A1 known.
  • the present invention seeks to develop an open-end rotor spinning, which is inexpensive to produce and has a recordable in a recording of a cover element Kanalplattenadapter, which is designed and positioned so that on the Kanalplattenadapterlagerung no false air in the Rotor housing can get.
  • a cover element Kanalplattenadapter which is designed and positioned so that on the Kanalplattenadapterlagerung no false air in the Rotor housing can get.
  • an open-end spinning device with a centering device designed according to the invention not only has the advantage that it always comes automatically when closing the open-end spinning device to an exact positioning of the spinning elements, but by the inventive design of the centering is also ensured that when the cover element is closed no false air can penetrate into the rotor housing. This means, even if the cover element and thus the guide surface of the channel plate adapter at the beginning of a closing operation With respect to the rotor housing and thus the arranged on the rotor housing guide means should not be positioned exactly, such a malposition is automatically corrected in the course of the closing operation by the positive connection of the centering device.
  • the centering device ensures that during the spinning operation always both the absolutely necessary, very accurate spatial allocation of the spinning components is met the most accurate or realized when closing the open-end rotor spinning and that also the entry of false air into the rotor housing reliably prevented.

  • the channel plate adapter is always properly positioned in the closed state of the open-end rotor spinning device, that is, it is reliably ensured that the one at the channel plate adapter arranged Fadenabzugsdüse and integrated into the channel plate adapter Faserleitkanal are always optimally positioned during the spinning operation with respect to the spinning at high speed spinning rotor.
  • the guide device arranged on the rotor housing has an annular groove for receiving a sealing element.
  • the sealing element is circular and preferably consists of a highly elastic material, for example rubber.
  • the annular groove also has an inner annular wall which serves as an axial stop for the channel plate adapter installed in the cover element. That is, when closing the lid member of the channel plate adapter is applied with its sealing surface not only to the sealing element, but also to the inner annular wall of the annular groove and thereby accurately positioned with respect to the spinning rotor in the axial direction.
  • the hitherto customary, manually operated adjustment means which often led to different, and often too adverse, settings of the spinning means of the numerous workstations, can be dispensed with.
  • the outer annular wall of the guide device has a radial recess in which an operating lever arranged on the cover element of a fixing ring for fixing the channel plate adapter can be positioned when the channel plate adapter is properly secured. That is, the open-end rotor spinning device can only be closed and thus converted to an operative working state, when the channel plate adapter is properly locked in the receptacle of the lid member, which can be seen by a proper positioning of the operating lever of the fixing ring.
  • the fixing ring is in turn pivotally mounted and can be positioned by means of the operating lever defined in a channel plate adapter insertion position or in a channel plate adapter locking position.
  • the channel plate adapter With the operating lever positioned in the channel plate adapter insertion position, the channel plate adapter can be easily installed or removed, but the open-end rotor spinning device can not be closed.

  • the channel plate adapter has a circumferential sealing surface which abuts when the open-end rotor spinning device is closed against a sealing element which is positioned in an annular groove of the guide device arranged on the rotor housing. That is, by the pressing of the circumferential sealing surface of the channel plate adapter to the arranged on the rotor housing sealing element is reliably prevented that during the spinning operation false air can enter the rotor housing of the open-end rotor spinning device.
  • the channel plate adapter can be fixed by means of a so-called multi-point locking in a receptacle of the lid member.
  • multi-point locking is a very safe during spinning operation and, if necessary, easily and quickly releasable locking device, with a channel plate adapter is safe, very accurate and easily replaceable positionable in a recording of the lid member.
