Definitions

  • the invention relates to an open-end rotor spinning device according to the preamble of claim 1.
  • open-end rotor spinning devices have a spinning rotor that rotates during the high-speed spinning process in a vacuum-pressurized rotor housing.
  • the forwardly open itself to the rotor housing is hermetically sealed during the spinning process by a cover element, in which a replaceable channel plate adapter is embedded.
  • the lid member usually also has an opening roller housing and bearing brackets for an opening roller and a Faserbandzu woolzylinder, and is connected via a pivot axis which is orthogonal to the axes of rotation of opening roller and Faserbandzu finallyzylinder limited movably connected to an associated spin box housing, for example, the storage and having the drive for the spinning rotor.
  • the individual fibers which are combed out of the opening roller from a master fiber sliver are conveyed via a so-called fiber guide channel to the revolving spinning rotor and are spun by this into a continuously removable thread.
  • the Faserleitkanäle these known open-end rotor spinning devices are usually formed in two parts. That is, usually in a bearing bore of the opening roller housing a Faserleitkanalprin is arranged, which has the input-side channel portion of a Faserleitkanals, while the output-side channel portion of the Faserleitkanals is disposed within an interchangeable Kanalplattenadapters, as mentioned above, in a corresponding receptacle in the lid member can be fixed is.
  • open-end spinning devices which are each equipped with a two-part Faserleitkanal.
  • An input-side channel section arranged in a fiber guide channel insert which is fixed in a bearing bore of the opening roller housing and an output-side channel section of a fiber guide channel arranged in the cover element or in a channel plate adapter are arranged such that the central longitudinal lines of the channel sections are inclined relative to one another at an advantageous angle.
  • Such an inclined arrangement of the channel sections of a fiber guide channel has proven to be advantageous with respect to the pneumatic fiber transport, in particular if the angle between the central longitudinal lines of the channel sections is exactly matched to the present yarn and / or spinning parameters.
  • An open-end spinning device with a Faserleitkanal having inclined channel sections is also the subject of EP 0 311 988 A1 ,
  • an open-end spinning device is described in which the input region of a fiber guide channel is incorporated into an opening roller housing and the associated output region of the fiber guide channel is part of a channel plate.
  • the angle of inclination between the input region of a fiber guide channel which is permanently integrated in the dissolving wafer housing and the exit region of a fiber guide channel arranged in the channel plate is thereby somewhat relieved that the output region of the fiber guide channel arranged in the channel plate is provided with an additional inclination angle.
  • the present invention seeks to provide an open-end rotor spinning device of the type described above, with a Faserleitkanal, the formation of which allows a simple way to optimize the fiber feed to the fiber sliding surface of a spinning rotor.
  • An open-end rotor spinning apparatus having a replaceable fiber guide passage insert securable in a bearing bore of an opening roller housing and wherein at least one passage portion extends at an inclination angle with respect to a reference line parallel to the outer wall of the fiber guide passage insert, the inclination angle respectively at an exit passage portion located in an associated passage plate adapter is tuned, has in particular the advantage that even after an exchange of the spinning rotor and the channel plate adapter, for example as a result of a change of yarn, by using a suitable Faserleitkanalucies can be ensured in a simple and cost-effective manner that between the channel sections is given a suitable inclination angle and thus optimal flow conditions are given in the fiber guide channel, at the same time an optimal Faseremployedspeisung on the Fa Serlois constitutional the spinning rotor is guaranteed.
  • the Faserleitkanal distract is integrally formed.
  • the stockpiling of Faserleitkanalein arrangementsn that differ in the inclination of their channel section, that is, adapted to different channel plate adapter, relatively uncomplicated.
  • the Faserleitkanallang has a concave curved sealing surface, which corresponds with an associated channel plate adapter. This sealing surface ensures that a pneumatically clean transition is provided between the outlet region of the inlet-side channel section and the inlet region of the outlet-side channel section.
  • the Faserleitkanallang may also be formed as a two-part component.
  • a first member fixable in a bearing bore of the opening cylinder housing has a first channel portion and an easily exchangeable second member securable to this first member is provided with another channel portion which is inclined with respect to the channel portion of the first member.
  • the inclination of the channel section part of the second component is in each case matched exactly to a specific channel plate adapter. This means that in a spin agent change with channel plate adapter replacement can by a corresponding Changing the second component of the Faserleitkanalcons be adapted to the new circumstances in a simple way the Faserleitkanal the open-end spinning device.
  • the second component can be easily connected to the first component via a connecting flange.
  • the connection flange has a groove for receiving a sealant.
  • the connection flange prevents, in particular in conjunction with a corresponding sealing means, preferably an O-seal, that false air can enter the Faserleitkanal. That is, it can be ensured by the connection flange that within the channel section parts of the fiber guide channel a largely undisturbed Saugluftströmung is pending, which is essential for a uniform pneumatic transport of the combed out by the opening roller individual fibers.
  • Faserleitkanal even with a two-part Faserleitkanalcommun the second component of Faserleitkanalconses in the exit region of the channel portion has a concave curved sealing surface. As already explained in connection with a one-piece Faserleitkanalprin, this sealing surface corresponds with an associated channel plate adapter and ensures that in the transition region between the channel sections a clean pneumatic transition is given.
  • open-end rotor spinning device carries the total number 1.
  • Such open-end rotor spinning devices have, as is known, a rotor housing 2, in which the spinning cup of a spinning rotor 3, which is supported with its rotor shaft 4 in the bearing gusset of a support disk bearing 5, rotates at high speed.
  • the rotor shaft 4 of the spinning rotor 3 is acted upon by a machine-long tangential belt 6, which is made by a pressure roller 7.
  • the axial fixation of the rotor shaft 4 on the support disk bearing 5 preferably takes place via a permanent magnetic thrust bearing 18.
  • the rotor housing 2, which is open towards the front, is closed during the spinning operation by a pivotably mounted cover element 8 into which a seal 9 is embedded.
  • the rotor housing 2 is also connected via a corresponding suction line 10 to a vacuum source 11, which generates the necessary spin pressure in the rotor housing 2.
  • a channel plate adapter 12 is arranged in a receptacle, which has the thread withdrawal nozzle 13, the outlet-side channel section 26 of a fiber guide channel 14 and the mouth region 27 of the fiber guide channel 14.
  • a thread withdrawal tube 15 connects.
  • an opening roller housing 17 is fixed to the lid member 8, which is mounted rotatably limited about a pivot axis 16.
  • the cover element 8 furthermore has bearing brackets 19, 20 arranged at the rear for supporting an opening roller 21 or a sliver feed cylinder 22.
  • the opening roller 21 is either driven by a single motor or, as shown in the exemplary embodiment, driven in the region of its whorl 23 by a rotating, machine-long tangential 24.
  • the drive of the sliver feed cylinder 22 can be done on a single motor or it is a worm gear assembly is provided, which is connected to a machine-length drive shaft 25.
  • the disintegrated in the opening roller 17 by the opening roller 21 from a (not shown) original fiber tape singled fibers are fed via the fiber guide 14 on the rotating at high speed spinning rotor 3, spun into a thread and then, as usual, wound into a cheese.
