Definitions

  • the present invention relates to a winding unit particularly for winding yarns.
  • a problem that is strongly felt in the production of synthetic yarns is the need to quickly wind the yarn produced by the machines at very high speeds, on the order of 6 m/s, and to load and remove the bobbins of yarn efficiently and quickly.
  • the most effective winding units currently commercially available are constituted by a rotating turret which supports, in a cantilevered manner, a pair of horizontal spindles.
  • a cardboard reel is fitted on each spindle and the yarn is wound on the reel alternately on one spindle while the other one is unloaded of the bobbin and loaded with a new reel.
  • This type of winding unit is capable of winding the yarn effectively, but it has the severe drawback that it does not allow to easily automate the operations for loading and unloading the reels and the bobbins of yarn.
  • the bobbins must in fact be extracted from the spindle outside of the profile of the turret to allow the insertion of a new reel on the spindle, performed either manually by an operator or by virtue of a robot.
  • Robots are capable of performing these operations, but they have the severe drawback of being very expensive.
  • GB-1,104,156 discloses an apparatus for collecting a yam, from a continuous supply, comprising a winding head arranged at an outlet producing at least one yarn, said winding head comprising at least two support members, each support member being adapted to rotatably support a winding member adapted to wind said yarn in order to form a bobbin, said winding head having at least two positions, namely a first position for winding a first said winding member and a second position for winding a second said winding member, each of said support members having a position for supporting said winding member for winding said yarn and a disengagement position for unloading said winding member and loading a new said winding member; said support member comprising an axially movable means which can move axially in order to engage the ends of said winding member and form said supporting and disengagement positions; said axially movable means comprising an end plate supporting two flanges adapted to engage the ends of said winding member, which is constituted by a tube; each
  • the aim of the present invention is to provide a winding unit which overcomes the above inconveniences of the cited prior art.
  • An important object of the invention is to provide a winding unit which allows to easily and cheaply automate the operations for loading and unloading the reels and bobbins.
  • a further object is to provide a winding unit which is constructively simpler.
  • a further object is to provide a winding unit which is reliable in use.
  • a further object is to provide a winding unit which disengages the full bobbin within the profile of the machine.
  • the winding unit particularly for winding yarns according to the invention comprises a winding head constituted by a rotating turret 3 having a base plate 5 which supports a pair of posts or bars, or similar supporting structures 7, which in turn support an end plate 9.
  • the end plate 9 includes at least two flanges 11 and 13 which can move axially by means of an actuation system, for example a pneumatic cylinder 15 and 17 respectively.
  • Each movable flange 11 and 13 lies opposite a respective base flange, 19 and 21, which is arranged on the base plate 5 of the rotating turret.
  • the base flanges 19 and 21 may also be axially movable by means of an actuation system, for example of the pneumatic type.
  • the two flanges 11 and 19 form a first support 23 for a reel 25 and the two flanges 13 and 21 form a second support 27 for another reel 25.
  • the reel 25 is constituted by cardboard cylinder which is suitable to support the wound yarn 29.
  • Each support 23 and 27 includes a motor, respectively 31 and 33, adapted to rotate the support 23, 27 to wind a yarn fed on the reel in a position associated with the flanges.
  • the winding unit according to the present invention includes a magazine means which is constituted by a casing 37 which is suitable to contain a plurality of reels 25 and includes a lower opening 39 which is arranged at the support 23 or 27 in the release position.
  • the opening 39 is formed on an oscillating portion 41 of the magazine which sets at least two positions: a position for feeding a reel (FIG. 5), in which the opening 39 is adjacent to the support 23 or 27, and a non-feeding position (FIG. 4), in which the opening 39 and the magazine are spaced from the support 23 or 27 in order to allow the rotation of the turret 3, which is suitable to move the full bobbin from the winding position to the release position.
  • a retention member 43 is provided at the opening 39 and is adapted to retain the reel 25 to be fed to the support 23 or 27 in a position in which it can be centered by the movable flanges.
  • the retention member 43 is pivoted to the oscillating portion 41 in contrast with an elastic means 45, so as to allow the oscillating portion 41 to move from the feeding position to the inactive position without interfering with the reel 25 once it has been locked between the flanges of the support.
  • the full bobbin in the position 27 is unloaded within the profile of the turret, with no need to provide external space.
  • a yarn 35 that arrives from a production head is fed to the reel 25 which rotates at a suitable speed and is thus wound onto the reel (the upper one, in the example shown in FIG. 3) by means of a winding device which essentially includes a freely rotating roller 47 which acts on the bobbin being wound and a cam and slider assembly 49.
  • the turret 3 rotates substantially through 180° and simultaneously moves the full bobbin into the lower position and the empty reel into the upper position for winding.
  • the rotation of the turret allows to supply the yarn 35 to the new reel continuously without interrupting the winding process, in a per se known manner.
  • the yarn is cut during the rotation of the turret, releasing the full bobbin 29, by virtue of a cutting device which is associated with the cam and slider assembly 49.
  • the lower bobbin is unloaded by virtue of the opening of the flanges 13 and 21 of the support 27 (or respectively 11 and 19 of the support 23).
  • the bobbin 29 can thus advantageously be collected by adapted conveyance or guiding devices 51 within the vertical profile of the turret and be removed from the winding unit.
  • a winding unit having been provided which is capable of automating the operations for loading and unloading the empty cardboard tubes and the bobbins, respectively, in a constructively simple, cheap and safe manner.
  • the great advantage of the winding unit according to the invention is indeed that it allows to automate the various auxiliary operations without the aid of expensive robots.
  • the materials used, as well as the dimensions, may of course be any according to the requirements and the state of the art.
