Definitions

  • the invention relates to a method of individual yarn spinning-in at an operating unit of a rotor spinning machine in which on a lifted bobbin there is first manually detected the yarn end, manually metered out the yarn length required for carrying out the spinning-in process, and at its end is formed, and then introduced into a delivery tube of the spinning rotor, a spinning-in yarn end.
  • the invention also relates to a device for carrying out said method on an open-end spinning machine each operating unit of which contains a spinning unit with a sliver feed device, a spinning rotor, and a yarn delivery tube over which, in the yarn travel path, there is situated a draw-off mechanism comprising a draw-off roller and a pressure roller seated on a swinging pressure lever, a yarn distribution mechanism and a yarn winding-up mechanism holding in its arms a bobbin, and comprising also a control unit connected with the sliver feed device.
  • the spinning unit of a rotor spinning machine comprises a textile fibre sliver feed device followed by a fibre singling out device out of which the singled out fibres are by means of underpressure led into the inner space of the spinning rotor and there collected on a collecting groove and due to the spinning rotor rotation transformed into a fibre band.
  • the yarn in process of production is led from the spinning rotor by an outlet tube and is drawn off by draw-off rollers and wound on a bobbin.
  • the presence of the yarn between the outlet tube and the winding device is monitored by a sensing device adapted to send out in case of a yarn rupture a signal intended to stop at least the sliver feed device.
  • the resumption of the spinning process comprises the steps of introducing the yarn end into the outlet tube of the spinning unit in the direction opposite to that of the yarn delivery into the outlet tube of the spinning unit and of letting it come to lie on the collecting groove of the rotating spinning rotor into which prior to this the feed of singled-out fibres has been resumed and a fibre band has been formed on the collecting groove of the spinning rotor. After connecting the yarn end to the fibre band, the draw-off motion of the yarn is resumed and yarn is produced from said fibre band.
  • the spinning-in can be carried out either manually or automatically by one of the well-known devices created for this purpose.
  • the operator When spinning-in manually after a yarn rupture, the operator first tilts the bobbin out of contact with its drive roller, detects the yarn end on the bobbin, winds off the required yarn length, and introduces then the yarn end into the outlet tube of the spinning unit into which the yarn end is sucked by the underpressure existing in the spinning rotor. Having introduced the yarn end into the outlet tube of the spinning unit, the operator tilts the bobbin in the winding device to its operating position in which it is in contact with the drive roller. During this movement, the operator resumes the feed of singled-out fibres into the spinning rotor.
  • the bobbin now in contact with its drive roller, begins to rotate, and the yarn newly in process of production begins to be drawn-off from the spinning rotor and wound on the bobbin.
  • the operator cannot influence the time interval during which the renewed fibre band is in connection with the yarn end.
  • the operator puts the yarn between the draw-off rollers responsible for the draw-off speed during the spinning.
  • the manual spinning-in can be successfully applied in rotor spinning machines operating at small draw-off speed of the yarn in process of formation which is adverse to the interest of both the producers and the users of the rotor spinning machines in raising the productiveness of such machines.
  • a time interval is required to speed it up to the circumferential velocity corresponding to the draw-off speed of the yarn. This time interval increases with the draw-off speed and with the increasing mass of the bobbin.
  • the instantaneous yarn speed of the yarn at the moment when the yarn end has reached the collecting groove of the spinning rotor is inferior to the operating draw-off speed of the yarn in process of production so that at the piecer (junction spot of the yarn end with the fibre band) a certain number of fibres with a twist number different from that of the neighbouring yarn section is being deposited.
  • the piecer then forms a thickened yarn section detectable by sight during the runner processing and representing a serious aesthetic defect not only of the yarn but also of the products made of it.
  • the manual spinning-in has been step by step replaced by the automatic one developed substantially in two directions, viz., either by means of mechanisms of the operating unit or by means of an attending device adapted to move along the machine and to stop at any chosen operating unit.
  • the spinning-in automation by means of mechanisms of the operating unit, for instance as disclosed in the CZ 200 910, has proved to be too complicated and expensive because it requires that the yarn delivery after its rupture is stopped with the yarn end remaining inside the delivery tube which is impossible to obtain at high yarn draw-off speeds.
  • the patent CH 481232 which is considered to be the closest prior art describes a device for collective yarn spinning-in. Before resuming the spinning, the yarn ready to be spun-in at all operating units is gripped between standing take-off rollers and occupies a prolonged path between the take-off rollers and the delivery tube. The take-off rollers stop of all the operating units as well as their spinning resumption takes place simultaneously.
  • the automated spinning-in by means of an attending device is at present the most widely used method of automatic yarn spinning-in on rotor spinning machines.
  • DE 1.807.023 describes a spinning-in device an an OE-spinning machine in which on each operating unit a roller is used to produce yarn supply which at a yarn rupture shortens and thus permits the yarn end not to leave the delivery tube. Both during the spinning-in and during the spinning, the yarn passes via a deflecting member.
  • the device can be used only for automatic spinning-in, not for the spinning-in in which the operator detects the yarn end on a stopped bobbin.
  • the bobbin rotates at all times since it cannot get out of contact with the distribution drum rotating in one sense during the spinning and in opposite sense during the spinning-in.
  • the time sequences of the beginning of the draw-off and winding in relation to the moment when the yarn end is let to get onto the collecting groove of the rotor cannot be adjusted, since they are controlled by a single common electromagnet.
  • the yarn end on the lifted bobbin is first detected by means of underpressure and sucked into a detecting nozzle.
  • the required yarn spinning-in length is unwound from the bobbin, the yarn is moved to the spinning unit and acted upon by the means of the attending device so as to assume its travel path passing via all means of the operating unit being attended except the yarn distribution mechanism.
  • the yarn spinning-in end which is in a first step by means of underpressure partly introduced into the spinning rotor.
  • the yarn is then acted upon by deflecting means of the attending device between the spinning unit and the draw-off mechanism of the attended operating unit of the machine and then, upon the suspension of this action, the spinning-in yarn end comes onto the collecting groove of the spinning rotor and is there continuously joined by the fibres of the fibre band generated in said collecting groove.
  • the yam is then exposed to the action of due means of the operating unit intended to draw-off, monitor, and wind the yarn that is then handed over from the attending device to the distribution device of the attended operating unit of the machine. This permits repeatedly to obtain the same quality and size of the piecer. High quality and small size of the piecer will be obtained even at high draw-off speeds of rotor spinning machines.
  • This method permits to increase the quality of the piecers and by means of this the quality of the resulting yarn which is substantially influenced by the quality of the piecers. It also increases the efficiency and reliability of the spinning-in operation while at the same time reducing the requirements imposed upon both the qualification level and the time of the operator.
  • the yarn is deflected from its travel path in front of the distribution mechanism and over the outlet aperture of the delivery tube, over the outlet aperture of the delivery tube being deflected by a distance equal to the distance between the spinning-in yarn end and the collecting groove of the spinning rotor, and the deflection over the outlet aperture of the delivery tube is cancelled after the spinning-in process has been completed.
  • a further improvement of the preceding method is achieved by cancelling the yarn deflection in front of the distribution mechanism only after the start of both the yarn draw-off by means of the draw-off mechanism and of the yarn winding by means of the winding mechanism thus handing the yarn over to the distribution mechanism and preventing it from the risk of being broken by the distribution mechanism during the spinning-in process.
  • the yarn is deflected only from the distribution device, and the deflection cancelling process is carried out in two steps the first of which, carried out before the spinning-in, returns the spinning-in yarn end onto the collecting groove of the spinning rotor, and the second one, carried out after the draw-off and winding have been started, sets the yarn free for the distribution mechanism.
  • the principle of the device for carrying out the above method on an open-end spinning machine consists in that the arms of the winding device and the pressure lever of the draw-off mechanism are coupled with a control electromagnet interconnected with a control unit, the control unit being connected also with a yarn deflecting member intended to deflect the yarn from its travel path, the yarn lying before and during the spinning-in process in its travel path between the draw-off roller and the pressure roller tilted away from the draw-off roller, of the draw-off mechanism.
  • the deflecting member is made as a deflecting member situated over the outlet aperture of the delivery tube.
  • the deflecting member is made as a deflecting member. of the distribution.
  • the deflecting member is adapted to take up two defined positions while in contact with the yarn, and more exactly, a position deflected to the maximum before the spinning-in, and a less deflected position during the spinning in.
  • a sensor of yarn presence and quality adapted to measure the quality and size of the piecer and coupled with the control unit so as to be able to stop the operating unit in case of bad quality of the yarn or of the piecer is situated between the outlet aperture of the delivery tube and the winding mechanism.
