Definitions

  • the invention concerns the method of cleaning the space between the guide tube of the continuous component of the multi-component yarn, and the inner surface of the rotor's hollow shaft when leading the continuous component into the spinning rotor of the rotor spinning machine for the multi-component yarn production which contains the continuous component and the component spun within the rotor from the singled-out fibres, while the guide tube of the linear material is placed concentrically inside the hollow shaft of the rotor.
  • the invention further concerns the device performing the above mentioned method of cleaning the space between the guide tube of the continuous component of the multi-component yarn and the inner surface of the rotor's hollow shaft when leading the continuous component into the spinning rotor of the rotor spinning machine for the multi-component yarn production, which contains the continuous component and the component spun out within the rotor from the singled-out fibres, where the rotor is mounted on the hollow shaft in whose cavity the guide tube for the linear material is placed basically concentrically, fixed inside the body where the rotor is placed.
  • linear material e.g. elastic yarn or elastic fibre
  • the linear material forms the continuous component of the multi-component yarn which is combined in the spinning rotor with the component spun from the singled-out fibres in the rotor.
  • the guide tube of the continuous component is placed inside the hollow shaft on which the rotor is mounted, the guide tube being fixed inside the rotor body after the loose end of the hollow shaft.
  • a space created Between the inner surface of the hollow shaft and the outside surface of the guide tube is a space created, preventing contact of the rotating hollow shaft and the static guiding tube.
  • particles of dust come loose during the spinning and settle in the space between the hollow shaft and the guide tube, gradually filling up the space.
  • the purpose of the invention is to prevent the settling of dust in the space between the hollow shaft and the guide tube to a maximum possible degree.
  • the aim of the invention is achieved through the method of cleaning the space between the guide tube of the continuous component of the multi-component yarn and the inner surface of the rotor's hollow shaft, based on the forced airflow being generated within the space between the guide tube of the continuous component and the inside surface of the spinning rotor's hollow shaft.
  • the forced airflow prevents the settling of dust and other particles of dirt between the guide tube and the inside surface of the spinning rotor's hollow shaft. This will extend the maintenance intervals of the work areas of the spinning machine and consequently increase the machine's productivity.
  • the forced airflow within the space between the guide tube and the hollow shaft's inner surface may be directed either towards the spinning rotor or away from the spinning rotor towards the end of the hollow shaft, as described within Claims 2 and 3.
  • the air flowing into the rotor prevents the dust from entering the space between the guide tube and the inner surface of the hollow shaft, the dust thus being kept within the rotor, spun into the spun-out component of the yarn and taken out of the rotor in the spun-out multi-component yarn.
  • the airflow from the rotor towards the end of the hollow shaft carries the dust across the space between the guide tube and the inner surface of the hollow shaft to the hollow shaft's end, whereby it also prevents its settling within this space.
  • the underpressure in the spinning rotor increases, thus compensating for the loss of underpressure needed for spinning, caused by the hollow shaft (hollow shaft).
  • the principle of the device performing the method of cleaning consists in that the space between the guide tube of the continuous component and the hollow shaft is connected to the source of the air overpressure or underpressure on the other side from the rotor.
  • the device created in this way does not require any mechanical adaptations to the hollow shaft and /or the guide tube - what it does need, though, is an additional source of power.
  • the solution requiring no additional power source to perform the method described can be achieved as set out within Claim 5, that is by providing at least one shape providing for the airflow generation on at least one of the walls forming the space between the hollow shaft and the guide tube.
  • the device for airflow generation between the hollow shaft and the guide tube consists of at least one projection and/or groove in the shape of a spiral.
  • FIG. 1 represents grooves both on the hollow shaft's inner wall and on the outer side of the guide tube
  • the model in Fig. 2 has projections on both the walls
  • the model in Fig. 3 has grooves on the hollow shaft's inner wall and projections on the outer wall of the guide tube
  • Fig. 4 represents the cross-section of the spinning unit whose hollow shaft's end on the far side from the rotor is connected to the source of air over- or underpressure.
  • the invention will be demonstrated example of the embodiment of the spinning unit of the rotor spinning machine for the multi-component yarn production, while the explanation will focus on those components relating to the solution based on the invention; the other elements of the spinning unit and spinning machine will only be described in the degree necessary for explaining the principle of the invention.
  • the spinning unit of the rotor spinning machine contains the spinning rotor 1 , which is fixed onto the hollow shaft 2 , pivoted by means of bearing 3 inside the body 4 .
  • the hollow shaft 2 is coupled to a tangential belt A , which drives the spinning rotor 1 .
  • the spinning unit also includes the feed device 5 of the sliver 51 and the singling-out device 6 , from which the singled-out fibres 61 are fed into the spinning rotor in the familiar way 1 to be spun into a spun-out component 81 of the multi-component yarn 8 .
  • the guide tube 7 of the continuous component 82 of the multi-component yarn 8 which loosely passes through the cavity of the hollow shaft 2 without touching its inner wall 21 and which is, by its end far from the rotor, 1 fastened inside the body 4 covering the rotor.
  • the continuous component 82 is combined inside the rotor 1 with the spun-out component 81 from the singled-out fibres to produce the multi-component yarn 8 , which is taken out of the rotor in the familiar way 1 by means of the guide tube 9 and spooled in the familiar way not represented here.
  • the inner wall 21 of the hollow shaft has a spiral groove 210 , which, while the hollow shaft revolves, 2 generates - between the outer wall 71 of the guide tube and the inner wall 21 of the hollow shaft - the airflow whose direction depends on the direction in which the spiral groove rises 210 and on the direction of revolution of the hollow shaft 2 and of the spinning rotor mounted on it 1 .
  • the model in Fig. 1 has a spiral groove created 711 on the outer wall 71 of the guide tube - it is advantageous with regard to this spiral groove 711 to select the same direction of rise as that of the spiral groove 210 inside the inner wall of the 21 guide tube 2 .
  • the spiral groove 711 is created on part of the outer wall 71 of the guide tube mounted 7 , and this part has a constant outer diameter.
  • the spiral groove 711 may be made along the whole length of the guide tube 7 passing through the hollow shaft 2 , that is along all diameter sizes of the guide tube mounting 7 .
  • the model in Fig. 2 uses the guide tube 7 of a constant diameter without a shoulder, on whose outer side 71 a spiral projection is made 712 , complemented by the spiral projection 212 on the inner wall 21 of the hollow shaft 2 .
  • spiral projections 212 and 712 can be made along the whole length of the relevant walls 21 , 71 forming the space between the outer wall 71 of the guide tube and the inner wall of the 21 hollow shaft, or the spiral projections may be made along part of their length or at least along part of the length of only one of them.
  • the model in Fig. 3 generates airflow in the space between the outer wall of the 71 guide tube and the inner wall of the 21 hollow shaft using the combination of the spiral groove 211 in the inner wall 21 of the guide tube and of the spiral projection 712 along part of the length of the outer wall of the 71 guide tube.
  • the end of the hollow shaft 2 opposite the spinning rotor 1 has an air box 200 connected, which is - in the model represented - coupled in a familiar way by means of air supply 201 to the source 202 of the air underpressure or overpressure.
  • the air underpressure or overpressure inside the air box 200 forces the airflow in the relevant direction between the outside wall 71 of the guide tube and the inner wall of the 21 hollow shaft.
