Definitions

  • the invention relates to a rotor spinning device with a fixedly arranged on the frame of a spinning machine, a bearing with a spinning rotor and a rotor housing having a supporting frame and a pivotally mounted cover element covering the rotor housing, which comprises a fiber sliver feed roller, an opening roller, a fiber guide channel immersed in a rotor opening and a thread take-off opening having.
  • Rotor spinning devices of the aforementioned type are known for example from DE 36 36 182 A.
  • This reference describes a spinning box with a suctioned rotor housing attached to the machine frame, in which a spinning rotor mounted on support disks rotates.
  • the rotor housing is airtightly sealed to the front by a channel plate arranged on a cover element, which has a shoulder which engages in the rotor.
  • the pivotably mounted cover element has an opening roller which is driven by a tangential belt via a drive whorl and a one-part fiber guide channel which extends between opening roller and spinning rotor.
  • the pivot axis of the cover element lies in the rear spinning box area, preferably above the drive shaft of the sliver feed roller.
  • the spin box can be opened to carry out, for example, maintenance work.
  • the cover element is unlocked and folded down about the pivot axis.
  • both the drive whorl of the opening roller and the worm wheel arranged at the end of the sliver feed roller disengage from the associated drive means, i.e. they lose contact with a circumferential tangential belt or a worm which is arranged on a drive shaft running in the machine longitudinal direction.
  • the sliver opening device therefore comes to a standstill.
  • braking of the spinning rotor is initiated via a lever linkage.
  • a disadvantage of this type of spin box is above all the installation position of the swivel axis.
  • the pivot axis arranged relatively far behind the rotor leads to unfavorable geometric conditions and thus to certain problems when pivoting the channel plate attachment having the fiber guide channel opening into the rotor opening.
  • Spinning boxes which have a one-piece, all pivoting base housing, which can be pivoted as a whole, which can be closed by a simple cover, and spinning devices which consist of two main assemblies.
  • the first main assembly is formed by a support frame which, in addition to a support disk bearing for the rotor shaft, also the rotor housing which is open towards the front having. This assembly is pivotally mounted about a horizontal axis of rotation arranged above the rotor housing.
  • the second main assembly consists of a cover element that closes the rotor housing. In addition to the sliver feed roller, this cover element has an opening roller and a one-piece fiber guide channel.
  • the pivot axis of the cover element is formed by a drive shaft for the sliver feed running in the machine longitudinal direction. Since the pivot axis of the cover element is also relatively far behind the rotor mouth in these spin boxes, the aforementioned problems also arise here.
  • the invention has for its object to improve the known rotor spinning devices.
  • the arrangement of the swivel axis according to the invention has the advantage that the channel plate attachment arranged on the cover element and having the fiber guide channel opening is subject to only a very slight vertical offset when pivoting into the rotor opening, i.e. the channel plate attachment slides horizontally and almost linearly into the rotor opening.
  • This rectilinear pivoting of the channel plate attachment makes it possible to position the fiber guide channel opening at a short distance from the fiber slide wall of the rotor, which is particularly advantageous with regard to the application of stretched individual fibers to the fiber slide wall and has a positive effect on the spinning result.
  • the special arrangement of the swivel axis also enables the integration of dirt separation directly into the cover element and thus the creation of a very compact, easily accessible rotor spinning device.
  • the dirt separator has a dirt chamber arranged below the opening roller, which is connected via a short, rear connection piece to a dirt suction line connected to a vacuum source via a filter chamber.
  • connection piece of the dirt chamber which can be pivoted with the cover element, and the dirt suction line fixedly attached to the machine frame have flange-like end regions with coordinated sealants which ensure that in the operating state, that is to say with the spinning box closed, the dirt chamber arranged below the opening roller is automatically sent to the Suction device of the spinning machine is connected.
  • the support frame receiving the rotor housing and the support disk bearing is fixed on the side of the box walls on the spinning machine base frame.
  • the box walls have cantilevers on their undersides, to which the cover element is pivotally attached via fitting elements.
  • the pivot axis is formed by short bolts or the like.
  • the bolts pass through slotted recesses in the side Fastening tabs the cover element are arranged and are secured by securing means that close the slotted recesses to the front.
  • the cover element can be easily removed in the open state after the securing means have been loosened, the replacement not being impaired either by the pivot axis or by the rear connecting piece of the individual dirt separator.
  • the arrangement of the swivel axis or the spinning box drives according to the invention which are preferably arranged at approximately the same height, in a row one behind the other, results in sufficient space below the support disk bearing or above the swivel axis for a dirt suction line and its coupling device with the connecting piece of the dirt chamber arranged in the swiveling cover element.
  • the tangential belt acting on the drive whorl of the opening roller from below is arranged between the swivel axis and a parallel, machine-long drive shaft for the sliver feed.
  • a winding machine designated overall by 1 is shown.
  • Such automatic winding machines have a central machine base frame 2, on which work stations 3 are arranged on both sides.
  • the work stations 3 each have a winding unit 4 and a rotor spinning device 5 as essential components.
  • the rotor spinning devices 5 process the sliver 7 placed in spinning cans 6 into a thread 8.
  • the thread 8 is wound on the winding units 4 to form a cheese 9.
  • the cross-wound bobbin 9 is held in a bobbin 10 during the winding process and is acted upon by a drive shaft 11 which rotates at an approximately thread take-off speed.
  • the rotor spinning devices 5 have a support frame 14 which is fixed to the machine base frame 2 via box walls 12 and corresponding fastening elements 13.
  • a rotor housing 17 is arranged on this support frame 14 in addition to a support disk bearing arrangement 15 and an axial bearing 16.
  • a spinning rotor 20 rotates, which is mounted with its rotor shaft 21 in the wedge gap of two pairs of support disks.
  • the rotor shaft 21 is, as usual, acted upon by the lower run of a tangential belt 22, which is started by a pressure roller 23.
  • the channel plate 25 has a centrally arranged projection 26 which projects over the channel plate 25 towards the front.
  • a thread take-off nozzle 27 and the mouth region of the fiber guide channel 28 are arranged in the extension 26.
  • the cover element 24, which is movably mounted on a pivot axis 29, also has the sliver dissolving components 30. That is to say, in addition to a sliver feed roller 31, which meshes with the worm 33 of a drive shaft 34 running in the longitudinal direction of the machine via a worm wheel 32 arranged at the end and which can be switched on in a defined manner via an electric coupling 35, in the cover element 24 there is an opening roller 36 and a one-part fiber guide channel 28.
  • the whorl 37 of the opening roller 36 is driven by the lower run of a tangential belt 38.
  • the opening roller housing and a dirt chamber 41 arranged below the opening roller 36 can be closed by a cover 39 which is secured by a bolt 40.
  • the dirt chamber 41 arranged below the opening roller 36 as part of an individual dirt separator 42 is connected via a rear connecting piece 43 to a dirt suction line 44, which in turn is connected to the vacuum source 19 via a filter chamber 51.
  • the coupling area 45 of these two lines lies just above the pivot axis 29, as shown in FIG. 2.
  • the pivot axis 29, about which the cover element 24 is tiltably supported, as indicated in FIG. 3, is preferably formed by short bolts 46 which are arranged in cantilevers 47 of the box walls 12 projecting forward.
  • the bolts 46 grip into slot-like recesses 49, which are arranged on fastening tabs 48 of the cover element 24.
  • the bolts 46 rotatably held in the slot-like recesses 49 are locked by means of securing means 50.
  • the arrangement of the pivot axis 29 approximately vertically below the rotor opening 52 also leads to the fact that the vertical offset to be taken into account when pivoting in the channel plate extension 26 becomes very small and therefore the mouth region of the fiber guide channel 28 can be placed very close to the fiber slide wall of the rotor 20, which is what has a very positive effect on the spinning result.
