Definitions

  • the present invention relates to a method for transferring the thread from a full bobbin to an empty tube according to the preamble of claim 1.
  • the invention further relates to a winder according to the preamble of claims 5 and 8.
  • the incoming threads When winding threads on winding machines with a turret carrying the winding mandrels, the incoming threads must be transferred from the full bobbin to an empty tube, which has been brought into the winding position by turning the turret, after the winding process has ended.
  • the transfer should take place waste-free and with the formation of an end bead consisting of an accumulation of threads on the full bobbin and a thread bead outside the traversing area on the sleeve of the new bobbin.
  • the first type of such devices axially displaces the sleeve or the coil mandrel with the sleeve during the coil change, so that the beads are produced at the desired locations.
  • These devices have the disadvantage that the spool mandrels rotating at high speed must be designed to be displaceable on the turret, which requires a high mechanical outlay when the spool mandrels are mounted on the turret.
  • a winding device in which the thread coming from the thread traversing, leading thread is deflected by a first thread guide in the form of a disengaging element acting on the thread running onto the spool into the plane of the thread slot on the empty tube.
  • the thread running to the full bobbin is deflected by means of a second element acting on the thread, which is located behind the first thread guide in the running direction of the thread and on which the turret carrying the bobbin mandrels is attached.
  • a third thread guide deflects the thread axially from the run-up point onto the second thread guide in such a way that the incoming thread comes to lie in the plane of the catch slot of the empty tube.
  • This known device has the disadvantage that the second thread guide, which is firmly connected to the turret and consequently can be rotated synchronously with the spools, deflects the thread still running to the full spool by more than 90 ° in a first plane running perpendicular to the spools and after the third thread guide engages, the thread is additionally deflected by an angle of more than 45 °.
  • Such strong deflections in the case of threads fed at high speed to the bobbin can lead to thread damage or even thread breaks.
  • the deflection of the thread by the second thread guide lasts for a very long time, starting shortly after the full bobbin swings away from the distribution roller until and at the time the thread is transferred to the catch slot of the new tube. Thread damage can consequently take place over a very long period, so that larger quantities are affected.
  • the object of the present invention is to provide a method for transferring the thread from a full to an empty tube, in which the thread running to the full, in the change position bobbin is deflected only for a very short time and the deflection of the thread only briefly experiences a further deflection during the transfer of the thread to the thread slot.
  • a bobbin winder 1 with two bobbins 5, 7 mounted on a rotatable turret 2, a thread laying device 6, is known Construction and the machine housing 9 shown, which contains the drive motors for the contact rollers 8, the laying device 6 and the other units and parts of the controller.
  • the turret 2, which carries the two mandrels 5, 7, has a known design and is rotatably mounted about the axis A.
  • the two bobbin mandrels 5, 7 are overhung on the turret 2, which means that the empty tube 11 can be loaded or the full bobbins 3 can be removed by hand or by an automatic doffer on the front side.
  • a thread deflecting rod 13 is visible, which is pivotably attached to the machine housing 9 on a crank 15 mounted on an axis B.
  • the end of an exchangeable plate 17, which will be described in more detail later, is visible behind the coil mandrel 7.
  • the contact roller 8 and the traversing device 6 are mounted so that they can move vertically on the machine housing 9 on a common carrier slide 10, so that the contact roller 8 can move upwards with increasing diameter of the coil 3 while maintaining a constant contact pressure.
  • the regulation of the contact pressure and the device for displacing the carrier 10 are known from the prior art and are not the subject of this invention. They are therefore not described in more detail.
  • the dash-dotted thread 14 runs from above to the machine and is changed by a thread guide 12 on the traversing device 6 in a known manner across the width of the bobbin 3 to be produced. Above the traversing device 6, a thread lifting device 19 for lifting the thread 14 out of the thread guide of the traversing device 6 is visible.
  • the thread lifting device 19 can consist of a thread lifting plate 21 which can be pivoted about an axis C.
  • a guide plate 25 which can be pivoted about the axis C in the thread run is intended to axially guide the thread 3 lifted from the traversing 6 into a plane Z running through the thread catching slot 23 on the sleeve 11 (see FIGS. 3B-10B).
  • an interchangeable plate 17 is arranged on a bracket 27 which can be pivoted about an axis G and can be pivoted from a rest position (FIG. 3A) via a take-over position (7A) into a transfer position (9A).
  • a rest position FIG. 3A
  • a take-over position 7A
  • a transfer position 9A
  • FIGS. 3A and 3B show the winding machine 1 at the time of the start of a bobbin change.
  • the full bobbin 3 is lifted off the contact roller 8 by turning the turret 2 clockwise.
  • the incoming thread 14, which is guided through an eyelet 29, is further changed by the thread guide 12 on the traversing device 6 over the entire stroke h1 of the still rotating bobbin 3 (FIG. 3B).
  • the deflecting rod 13 is pivoted into the thread path of the thread 14 from the left side, visible in FIG.
  • FIG. 5A it can be seen that when the revolver 2 with the full bobbin 3 and the empty sleeve 5 is pivoted further, the carrier slide 10 has lowered and as a result the free thread length between the oscillation 6 and the bobbin 3 with respect to the conditions in FIGS.
  • the thread 14 is now guided axially laterally out of the traversing area (stroke) in order to reach plane Z (guide plate 25) on the one hand and plane X (hook 31) on the other hand.
  • the deflecting rod 13 can pivot back and release the thread transfer.
  • the fixed hook 31 and a pivotable hook 33 are attached to the interchangeable plate 17 (FIG. 11).
  • the fixed hook 31 determines the axial position for the end bead 37 on the surface of the full coil 3 (dash-dotted line X).
  • the hook 33 which can be swiveled back about the axis 41 behind the front edge 39 of the interchangeable plate 17 lies in the swiveled-back position within the interchangeable plate 17.
  • the interchangeable plate 17 pivots further, feeds the thread 14 and causes the empty sleeve 11 to be looped through the thread 14 (FIGS. 8A and 8B).
  • the thread 14 reaches the area of the thread catch slot 23, it is grasped by the latter and the section of the thread 14 running to the full bobbin 3 is torn in two.
  • the lifting plate 21 swings back into the starting position, so that the thread 14 from the thread guide 12 in the Traversing device 6 detected and the construction of a new coil 3 can be started.
  • the position of the turret 2 is again the same as in FIGS. 3A and 3B at the start of the changing process.
  • the carrier 10 with the traversing device 6 and the contact roller 8 is in an almost completely lowered position due to the still small amount of thread on the sleeve 11.
  • the carrier 10 With increasing diameter of the bobbin, the carrier 10 also moves upwards successively until the bobbin 3 contains the prescribed amount of thread and the changing process according to FIGS. 3A and 3B begins again.
  • a thread deflector 42 in the form of a plate can be swung out on the interchangeable plate 17 synchronously with the second hook 33 and over the hook 31 be positioned (Fig. 2,11).
  • a direct drive for the mandrels 5 carrying the sleeves 5 can also be installed.
  • the coil 3 is driven directly, it is in contact with a driven speedometer roller, which is arranged at the location of the contact roller 8.
