Definitions

  • the present invention relates to an apparatus of a spinning line and a method for transporting bobbins and tubes between a roving frame and a spinning frame.
  • the bobbins formed at the roving frame consisting of a tube on which the roving stretched at the frame is wound, are transported to the spinning frame.
  • the bobbins being worked are located, hanging from a loom, from which the rovings to be worked start.
  • the bobbins being worked are exhausted, they are replaced by bobbins originating from the roving frame.
  • exhausted bobbins consist of the tube completely devoid of roving (defined as “empty tube”) or of the tube provided with some roving residues windings (defined as “dirty tube”).
  • the dirty tubes (and sometimes even the empty ones) are cleaned in a special device, usually called "cleaner", which removes the residual roving, thus obtaining empty tubes.
  • the empty tubes originating from the cleaner and those collected from the spinning frame are brought back to the frame and replaced here with the bobbins that have been formed in the meantime; the empty tubes may thus be reused to form new bobbins.
  • the tendency is to further speed up the performance of such operations, above all because of the tendency of the roving frames and of the spinning frames to foresee an ever increasing number of spindles.
  • numeral 1 indicates, overall, a portion of a spinning line comprising a vessels region 2, in which a plurality of vessels 4 is housed, each containing a roving roll, a roving frame 6 adjacent to the vessel region 2, to be fed the roving therefrom, and a plurality of spinning frames 8, for example arranged parallel to one another.
  • the frame 6 stretches the roving originating from the vessels 4 and winds it on empty tubes, forming bobbins 10 to be transported to the spinning frame.
  • the bobbins 10 are made available to a carrier 20 of the frame 6.
  • a transport system comprises a frame side transport device 22, usually called “rail”, adapted to collect the bobbins 10 from the carrier 20 and to move them in suspension, at a predetermined height, generally by means of a main belt 22'.
  • the frame side transport device 22 is further adapted to load the carrier 20 with empty tubes 14.
  • the roving frame 6, which extends along a frame axis along which working points are distributed successively, provides for a pair of flaps 6a for each working point.
  • Each flap 6a is rotating about a vertical axis, to guide the roving in the winding around an empty tube 14, thus forming the spool 10.
  • the empty tube 14 is removably inserted on a spindle 6b integral with the spindle moving carrier 20.
  • the carrier 20 In a working position ( Figure 2 ), the carrier 20 is arranged at a height adapted to allow the winding of the roving around the tube, so as to produce the spool 10.
  • the axes of the spindles carried by the carrier 20 substantially coincide with the axis of the flaps.
  • the carrier 20 is lowered, from the raised working position to a lowered retracted position, in which it cooperates with carrier translation means for the horizontal translation of the carrier towards the advanced doffing position below the rail.
  • Said horizontal translation means comprise a slide 6c which cooperates with motor means for the horizontal translation of the carrier.
  • the carrier 20 moves into the advanced doffing position adapted to allow the cooperation of said carrier 20 with the spool carrying rail 22, to doff the spools from the carrier and/or arrange new empty tubes 14 on said spindles 6b for the formation of new spools.
  • the rail 22 is supported by a support and guiding structure 6d, comprising a vertically movable crosspiece 6e.
  • the rail 22 is thus vertically movable between a raised position, in which the moving of the spools towards the next processing occurs, and a lowered position adapted to collect the spools from the carrier in the doffing position.
  • the frame 6 comprises support and moving means adapted to support said rail and to allow the vertical movement thereof.
  • said support and moving means comprise a preferably flat band 6f, connect, at an end, to the crosspiece 6e and wound, at the opposite end, to a rail moving shaft 6g connected to a motor.
  • the transport system further comprises a spinning frame side transport device 26 adapted to move the bobbins 10 towards the spinning frames 8 and the dirty tubes 12 (or sometimes empty 14) towards the frame 6.
  • the secondary device 26 has a closed ring shape and comprises a track 26' having sections 8' which run parallel to the spinning frames 8, seamlessly.
  • the transport system comprises management means, comprising, for example, a PLC or a microprocessor, adapted to command the advancement of the spools along the rail and the advancement of the empty 14 or dirty tubes 12 along the track 26'.
  • management means comprising, for example, a PLC or a microprocessor, adapted to command the advancement of the spools along the rail and the advancement of the empty 14 or dirty tubes 12 along the track 26'.
  • the spinning line 1 comprises an integrated device 50 adapted to cooperate with the frame side transport device 22 which serves the frame 6 and with the spinning frame side transport device 26 which serves the spinning frames 8, to locally carry out, i.e., in a predetermined area of the transport system, the removal of the dirty tubes 12 from the secondary device 26 and of the bobbins 10 from the primary device 22, possibly the cleaning of the dirty tubes 12 to obtain empty tubes 14, the exchange of the bobbins 10 with the empty tubes 14 and the release of the bobbins 10 to the secondary device 26 and of the empty tubes 14 to the primary device 22.

  • said vertical translation means comprise a vertical translation actuator 60, engaged between the central body 56 and the transmission element 59 and adapted to raise/ lower said central body 56 by virtue of the fact that the stems 57a, 57b are slidingly engaged with the central body 56.
