Definitions

  • the present invention relates to a flyer wing with a pivot, with two wing arms extending away from it and with a guide channel for guiding a roving from a drafting device to a pivotally arranged press finger, which has a yarn guide at its free end, the guide channel partially is formed by a guide tube which is carried by two pivot bearings and runs parallel to one of the arms and is connected to the press finger, the pivot bearing facing the pivot being provided in the associated arm.
  • a flyer wing of this type is known from FIGS. 5 and 6 of CH-A-424 562.
  • This known flyer wing, as well as the also known flyer wing from DE-B-1 685 910, is designed as an open wing, which has the disadvantage that the mutual spacing of the lower ends of the wing arms increases at higher rotational speeds of the spinning wing . As a result, the quality of the roving suffers and its winding on the sleeve located between the wing arms is no longer clean and even.
  • By expanding the wing arms there is also the risk of wing breaks and thus the risk of injury to the personnel.
  • the wing arms are relatively stable, in some cases using lighter materials, so that the centrifugal forces to be controlled are also reduced in this way.
  • the object on which the invention is based is therefore to design a flyer wing of the type mentioned at the outset in such a way that it is suitable for higher speeds with low air resistance and weight.
  • the invention provides that the two arms are firmly assembled at their ends remote from the pivot with a ring, that the guide tube is arranged outside the associated arm, the guide tube and the associated arm being arranged one behind the other in the circumferential direction that the guide channel is closed over its entire guide path, and that the pivot bearing, which is removed from the pivot, is provided for the guide tube either on the ring or on an attachment located at the end region of the associated arm.
  • IT-A-644 365 also shows a flyer wing in which the two arms are firmly assembled with a ring at their ends remote from the pivot.
  • a spring arranged outside the associated arm is provided for generating the desired contact pressure of the pressure finger, which will lead to increased air resistance at higher speeds and catch fly fibers.
  • the guide channel is partially formed by a guide tube (25) which is arranged outside the associated arm and merges into the press finger at its lower end.
  • the guide tube is arranged radially outside of the associated arm and would therefore lead to an unacceptably high air resistance at higher speeds.
  • the upper part of the guide channel is formed by the upper part of the arm in question and the yarn is not guided over its entire guide path through a closed guide channel, at least not in the transition region from the upper part of the guide channel into the guide tube.
  • the yarn is thus unprotected in this transition area, which would have a disadvantageous effect at higher speeds of the flyer wing, quite apart from the fact that the transfer of the guide yarn from the upper part of the guide channel into the guide tube due to the geometry changing during a pivoting movement of the press finger is not without problems.
  • a preferred embodiment is characterized in that a prestressing element acts on the guide tube and exerts a torque on it, by means of which the press finger is biased against a roving spindle arranged concentrically to the axis of rotation of the flyer wing.
  • This embodiment is preferably further developed in that a stop element is attached to the wing arm assigned to the guide tube, by means of which the end position of the guide tube caused by the pretensioning of the prestressing element is defined and that the position of the stop element is adjustable. This enables adjustment of the end position of the press finger.
  • the guide channel comprises a feed channel located inside this arm part for feeding the roving supplied by the drafting device to the input end of the guide tube
  • the outlet end of this feed channel is preferred extended into the end of the guide tube facing the pivot to advantageously form the swivel bearing removed from the press finger.
  • This arrangement is preferably further developed in that the prestressing element is clamped between the wing arm assigned to the guide tube and the guide tube and preferably surrounds the outlet end of the feed channel. In this way, the biasing element is accommodated without difficulty.
  • a tube piece continues from the latter, the free end thereof being directed toward the yarn guide of the press finger. This greatly reduces the formation of fiber fly due to the increased speeds.
  • the pipe section preferably extends to over half the length of the press finger.
  • the guide tube and / or the pipe section can be at least partially made of non-metallic material such. B. ceramic.
  • the flyer wing shown in FIG. 1 has a hollow cylinder 12 or pivot pin provided with a bore 11, which is rotatably mounted in a bearing (not shown).
  • An arm part 14 having a tubular feed channel 13 extends from this pivot pin 12.
  • the lower ends of the arm 14, 15 and the arm 15 are assembled with a horizontal ring 17.
  • the arm 16 is firmly connected to the ring 17 by means of a screw 18, but any type of fastening, such as, for. B. casting in a single piece comes into question in the context of this invention.
  • a guide tube 22 is carried by an upper pivot bearing 20 and by a lower pivot bearing 21.
  • the upper pivot bearing 20 is attached to the arm part 14.
  • the lower d. H. the pivot bearing 21 removed from the pivot is installed in the ring 17 in the example shown.
  • the bearings 20, 21 are arranged with respect to the guide tube 22 in such a way that the tube 22 is pivoted about its longitudinal axis 23.
  • the feed channel 13 advantageously has a short tubular extension, which extends into the guide tube 22 to form the upper bearing 20.
  • it can, for example, also be attached to an extension which extends to the location of the bearing 21 and which is located at the lower end of the lower arm part 15.
  • a press finger 25 is fixedly connected to the guide tube 22. It has at its free end a yarn guide 26 for the roving, which is provided with an eyelet 27.
  • a bent tube piece 30 forms a continuation of the guide tube 22. Its free end is directed against the roving guide 26.
  • the bore 11, the feed channel 13, the guide tube 22 and the bent tube piece 30 together form a guide channel for the roving formed during operation of the flyer wing.
  • the pipe section 30 is attached to the press finger 25 in the example shown.
  • a spindle (not shown) is provided for each spinning station, the axis of rotation of which coincides with the axis of rotation 31 of the corresponding flyer wing. This is by means of a biasing element formed by a coil spring 32
  • the guide tube 22 is also connected to a counterweight 33, which is also pivotable with the guide tube 22 about its longitudinal axis 23.
  • the counterweight 33 is subjected to an outward centrifugal force. This generates a torque which is opposite to that generated by the press finger 25.
  • the pressure finger 25 is pressed against the spindle in the same direction of rotation by the counterweight 33 as is the case with the helical spring 32.
  • the torque generated by the counterweight 33 and the pretension generated by the spring 32 endeavor to rotate the guide tube 22 clockwise according to the view in FIG. 2.
  • a stop member 34 serves to limit such a movement. In the example shown, it is designed as a screw which is attached in the arm part 15. By turning the screw 34, the one end position of the pivoting of the pressing finger 25 can be set as desired.
  • the fiber sliver is guided by a drafting device, not shown, through the guide channel, which, as already mentioned, comprises the bore 11, the feed channel 13, the guide tube 22 and the bent tube piece 30.
  • the rotation of the flyer wing of the fiber sliver supplied by the drafting device continuously gives a rotation, so that when emerging from the tube 30 there is a roving which is spooled as roving by means of the pressing finger 25 onto the spindle, not mentioned, which is concentric with the axis 31 and which was mentioned above becomes.
  • the spindle is also subjected to constant rotation about its own axis, which is identical to the axis 31.
  • the press finger 25 is constantly biased against the spindle or a sleeve attached to it, or pressed against it, and places a winding on these roving windings. It should be pointed out at this point that the term "roving” is used in the claims for simpler expression, although it is a spinning process in which immediately after leaving the drafting system, i. H. before entering the bore 11, a roving having a certain twist is not yet present.
  • This flyer wing has the further advantage that the roving rotating about the axis 31 is in a closed channel for practically the entire part of its way during the spinning process and thus there is practically no blowing of the fibers due to the extraordinarily high rotational speeds. This also greatly reduces the formation of fiber fly in the spinning hall. For these reasons, it is advantageous to make the curved tube 30 relatively long; because this will further shorten the length of the roving that is outdoors.
  • this flyer wing is very advantageous if it is used in a machine with automatic bobbin change, in which the roving bobbin is removed upwards and the new, empty sleeve is reinserted from above.
  • the flyer wing in these machines is inclined in such a way that the plane defined by the arms 14, 15 and 16 reaches an inclined position relative to the spindle axis. Thanks to the fact that, due to the spring 32, even when the wing is at rest, the pressing finger 25 bears against the winding of the bobbin, when the bobbin is moved upward, the roving between the eyelet 27 and the winding is separated with great reliability and at the desired location.
