Definitions

  • the invention relates to a winding machine for the continuous winding of threads according to the preamble of claim 1.
  • winding machines which wind a thread continuously without interrupting the process to coils.
  • winding machines have a plurality of winding spindles, which are held on a movable spindle carrier and by means of the spindle carrier alternately in a winding area for winding the threads and in a changing area for removing the finished coils and attaching new sleeves.
  • the yarn change from a first winding spindle to a second winding spindle is automatic, so that no interruption of the spinning process is required.
  • a winding machine with a rotatable spindle carrier, on which two cantilevered winding spindles are held has a loading device for attaching the sleeves to an empty winding spindle in the change region.
  • the loading device has a gripping arm, which is pivotally mounted on an axle.
  • the gripper arm is axially displaceable on the axis.
  • For attaching a sleeve On the winding spindle held in the change area a sleeve is removed from a sleeve magazine by the gripping arm and attached by pivoting and axial displacement on the empty winding spindle. In this case, the position of the winding spindle remains unchanged in the change region.
  • such a loading device is not suitable for winding machines, in which the spindle carrier carries out an evasive movement in order to allow a winding increase in the winding area on the winding spindle held in the winding spindle.
  • the spindle carrier carries out an evasive movement in order to allow a winding increase in the winding area on the winding spindle held in the winding spindle.
  • stopping the spindle carrier for changing the full bobbins or attaching the sleeves is hardly possible.
  • the invention is characterized in that a movement of the winding spindle in the changing range is uncritical effect on the loading of the winding spindle with new sleeves.
  • the guide means for attaching the sleeves is formed at least for a short period of time synchronous with the moving spindle spindle through the spindle spindle feasible. This increases the time window in which the insertion of the sleeves can be done on the winding spindle.
  • the guide means follows the winding spindle for a short period of time, so that the rotational movement of the spindle carrier, which is required for the winding of the threads of a second winding spindle, does not have to be interrupted.
  • a simple positioning is effected in that the guide means is arranged laterally adjacent to the spindle carrier and between a standby position and an operating position laterally to the winding spindle can be guided and that the guide means in the operating position with the winding spindle is mechanically coupled.
  • a slight alignment of the guide means to the winding spindle is possible. Even during the rotational movement of the spindle carrier, there are no significant alignment errors between the free end of the winding spindle and the guide means.
  • the guide means advantageously has a sliding shoe, which rests in the operating position on the winding spindle and provides for the mechanical coupling.
  • the movement of the winding spindle and the movement of the guide means is advantageously carried out by the drive of the spindle carrier in the phase of the mechanical coupling.
  • the coupling can also be carried out by electronic means.
  • the guide means is advantageously designed to be horizontally movable.
  • both the positioning of the sleeves before the free end of the winding spindle and the sliding of the sleeves on the winding spindle can be performed by the guide means.
  • the guide means is formed by a trough-shaped support plate, which is held at one end to a pivot axis and which has an opening at the opposite end for discharging the sleeves held in succession in the carrier sheet. This can advantageously be positioned and pushed several sleeves simultaneously. A single handling of the sleeves is not required.
  • the pivot axis with the support plate is in this case preferably held on a carriage, which is guided in the lower region of the machine frame parallel to the winding spindles in the change region. This leaves the sleeves open put a simple way in the positioned carrier sheet on the winding spindle.
  • the support plate preferably has a width which corresponds to the total length of the tensioned on the winding spindle sleeve.
  • the support plate preferably has a width which corresponds to the total length of the tensioned on the winding spindle sleeve.
  • Another particularly advantageous embodiment of the invention allows positioning of the sleeves on the winding spindle.
  • the plugged as a sleeve column sleeves would then be positioned by separate means on the winding spindle. Due to the design of the support plate, which is divided in its width into several separate compartments, each winding position can assign a compartment in the support plate, so that the held in the tray sleeves are assigned to the specific winding position.
  • the distances between the subjects are designed according to the distances to the positioning of the sleeves on the winding spindle. When sliding the sleeves onto the winding spindle, the sleeves can thus be assigned to the positions of the winding positions.
  • the development of the invention is advantageous in which the carrier sheet has a depth for accommodating a plurality of sleeves per winding point.
  • the tracking of the sleeves in a dispensing position on the support plate in a simple manner can be achieved in that the support plate in the waiting position with the bearing end is higher than with the opposite end, so that the carrier plate has an inclined position.
  • the development of the invention is particularly suitable, in which the loading device has a sleeve magazine, which is connected to the guide means.
  • the placement device In order to perform the movements for positioning and attaching the sleeves as quickly and accurately as possible, the placement device has a vertical drive and a horizontal drive, which are independently controllable for moving the guide means.
