Definitions

  • the bobbins formed at the spindle frame consisting of a tube on which the roving stretched at the roving frame is wound, are transported to the spinning frame.
  • the bobbins being worked are located, from which the rovings to be worked start.
  • the bobbins being worked are exhausted, they are replaced by the bobbins originating from the spindle frame.
  • the exhausted bobbins consist of the tube completely devoid of roving (defined as “empty tube”) or of the tube provided with some windings of roving residues (defined as “dirty tube”).
  • the dirty tubes (and sometimes also the empty ones) are cleaned in a special device, usually referred to as "cleaner", which eliminates the residual roving, obtaining empty tubes.
  • the empty tubes originating from the cleaner and those removed from the spinning frame are brought back to the roving frame and replaced here with the bobbins which have been formed in the meantime; the empty tubes may thus be reused for the formation of new bobbins.
  • the Applicant has devised a further apparatus, object of the Italian patent application for the invention No. 10 2017 000 037 751 , capable of reducing the overall execution times of the removal, exchange and release stages, and possibly of the cleaning one.
  • the execution speed of the exchange operations is not the only requirement.

  • the exchange device allows overcoming the different distances possibly existing between the tubes carried by the spinning-frame transport device and the bobbins carried by the bench-side transport device.
  • the exchange device allows reducing the overall time necessary for the exchange of the bobbins with the tubes, and possibly the cleaning of the dirty tubes.
  • the use of electric motors for the radial motion means and the rotary motion means allows the peg carrier group to be always rotated in the same direction, to the advantage of the operation of the exchange device.
