Definitions

  • the invention relates to a thread-laying device for thread-winding processes.
  • thread winding processes use winding machines with dozens of winding units, each of which has a thread laying device.
  • Such thread-laying devices serve to reciprocate a yarn to be wound up on a rotating bobbin or yarn package in the direction of the longitudinal axis of the bobbin by means of a high-frequency traversing movement.
  • so-called impeller thread laying devices have proven not least because of their simple structural design and their reliability.
  • Such thread laying devices are characterized by two impellers, which are driven in opposite directions about their respective axis of rotation.
  • the impellers usually each have two or three wings, which extend away from the axis of rotation of the respective impeller in the radial direction.
  • the réellespulende on the yarn package thread is guided during the winding process in constant change to the wings of the one and the other impeller and is thereby reciprocated in the sense of a traversing movement relative to the coil in the direction of the coil longitudinal axis in rapid succession.
  • the thread is mostly on a bow disc or plate, ie on a so-called thread guide ruler, out of whose contour the wings of the impeller emerge during operation and in which they dive again in the region of immersion points.
  • a yarn transfer between the impellers and a consequent stroke reversal of the traversing movement of the thread takes place in each case in the region of the immersion points of the wings of the vanes, which coincide in the axial direction of the coil with the reversal points of the traversing movement of the thread.
  • Such a impeller thread laying device is for example from the WO 2015/007339 A1 known.
  • a so-called thread reserve must be created on the bobbin to be wound with the thread.
  • a second coil is knotted, which is referred to as a reserve coil.
  • another coil is now available for the current processing process. This can be changed after processing the first yarn package without interruption to the reserve coil.
  • a responsible operator can replace the empty coil with a new reserve coil and tie.
  • the thread reserve must be created by the winding process mandatory at the beginning of the winding process.
  • the thread reserve must be arranged on the spool usually outside of the device-specific basic or normal stroke width of the impeller thread laying device.
  • the task relating to the thread-laying device is achieved by a thread-laying device having the features specified in claim 1.
  • the winding machine according to the invention has the features specified in claim 8.
  • Preferred developments of the invention are subject of the dependent claims.
  • the thread laying device comprises a first and a second impeller, each having a plurality of wings, which extend away from a rotational axis of the respective impeller in a radial direction.
  • the impellers may each have two, three or more wings.
  • Each impeller is associated with an electric motor, wherein the two impellers are driven in opposite directions by means of the two electric motors about their axes of rotation in a respective traversing direction to reciprocate a réellespulenden on a rotating spool along a traverse axis.
  • the traversing axis of the yarn movement in a conventional manner to the longitudinal axis of the wound with the thread coil to be aligned parallel.
  • the thread laying device enables the positioning of the thread at a predetermined axial position along the traversing axis of the thread movement, without the need for a complex additional facial expressions mentioned above. This can rather be completely eliminated.
  • the thread laying device allows important special functions in winding processes, such as the creation of a thread reserve, a mecanicwickels and an automatic bobbin change with automated separation of the thread, for which the thread at a predetermined axial position in the direction of the traversing axis of the yarn laying device or with the thread to be wound coil, preferably fixed in position, must be positioned.
  • the yarn laying device can be provided overall with a simpler structural design and in a cost effective manner.
  • the thread is guided in the predetermined axial position on both sides between the wing front sides of the wings of both vanes and thus secured against undesired axial slipping from the predetermined axial position.
  • the thread is splinted or held in the predetermined axial position on both sides by the wings of the two impellers.
  • the thread is preferably on the respective wing front sides of both impellers. It is understood that the thread between the wing front sides of two wings of the impellers may not be clamped (held) to allow a free and trouble-free yarn path in the direction of the coil to be wound and at the same time to avoid excessive stress on the thread.
  • the control device is preferably programmed so that the impeller already leading the leading impeller always directly, ie over a minimum required angular distance to move in a corresponding with the predetermined axial position rotational position.
  • the predetermined axial position of the thread for example in the direction of traversing the thread leading vane arranged in front of the leading thread of the impeller, this impeller is rotated with its leading the yarn in traversing direction until the yarn is arranged in the predetermined axial position.
  • the predetermined axial position is arranged in the traversing direction of the leading wing behind this wing of the impeller, so the thread (still) leading impeller with its thread leading wing counter to its traversing direction in one with the predetermined axial position of the thread corresponding rotational position moves or rotated.
  • the thread is moved in this case by the other impeller in its traversing direction in the predetermined axial position.
  • the thread can be positioned at a predetermined axial position within and in particular also outside a device-specific maximum traverse stroke of the thread-laying device.
  • the thread is in any case at a wing back, i. the leading edge in the direction of trailing wing front side or edge of the thread leading wing to.
  • the thread can be positioned further away from the lifting center of the thread-laying device with the wing back, because the respective impeller is arranged with its axis of rotation in the direction of the longitudinal axis closer to the predetermined axial position of the thread than the respective other impeller.
  • the control device can be programmed to control the electric motor of each other impeller so that this is rotated by means of an opposite direction of its traversing rotational movement until the thread between the wing back one wing of the one impeller and the wing back of a wing of the other impeller is guided.
  • the thread is in this case therefore by the wing backs of two wings in the given Held axial position.
  • the thread can only be positioned at a predetermined axial position within the device-specific maximum traversing stroke of the thread-laying device.
  • the yarn laying device according to the invention can fulfill a further special function.
  • the control device according to the invention can be programmed to control the electric motors of the two impellers after positioning the thread at the predetermined axial position such that they move the thread oscillating about the predetermined axial position.
  • broader base thread reserves or final wrap / abdominal bandages can be generated on the bobbin, whereby the thread can be simplified and reduced noise can be removed from the spool. It is understood that the oscillating movement of the thread, in contrast to the traversing movement of the thread when producing the thread winding has only a small axial oscillation of a few (about two to five) millimeters.
  • the thread laying device has a drive, by means of which the thread guide ruler and the axes of rotation of the two vanes are movable relative to each other.
  • the control device is preferably programmed to deliver the yarn guide ruler and the axes of rotation for positioning the yarn at the predetermined axial position along the traversing axis.
