Definitions

  • the empty sleeve has a catch groove in a normal plane which lies to the side of the traversing area. To insert the thread into the catch groove, the thread must therefore be guided in this normal plane. The traversing speed must therefore be suspended. Therefore, the thread piece between the empty tube and the upstream delivery mechanism is very relaxed, which can lead to the thread forming a winder on the delivery mechanism. In addition, at the moment of catching, the empty tube is driven in such a way that the empty tube and the thread have opposite speeds in the peripheral region in which they touch.
  • the object of the invention is to eliminate this Verschlappungsekkekt or to eliminate so far that the risk of disturbing the bobbin change, in particular the risk of winder formation on the upstream delivery mechanism is eliminated.
  • the deposit angle alpha is less than / equal to 4 °, preferably less than / equal to 3 °.
  • the traversing speed is reduced continuously or at most in small steps, and within a very short time in relation to the total winding time (winding travel) of a full package, preferably with a winding layer thickness of not more than 1 mm.
  • This process can - as suggested by claim 11 - advantageously be connected to the first phase of the bobbin changing process if the method is applied to winding machines in which of two spindles alternately one is in operation and the other is in a waiting position.
  • the winding device consists of the traversing device with reversing thread shaft 2 and traversing thread guide 3.
  • the traversing thread guide 3 is guided back and forth in the grooves 4 of the reversing thread shaft and straight in the straight guide 5.
  • the traversing thread guide 3 is guided back and forth in the grooves 4 of the reversing thread shaft and straight in the straight guide 5.
  • the thread 6 is laid on the winding tube 7 to form a package 8.
  • the sleeve 7 is firmly clamped on the winding spindle 9.1.
  • the winding spindle 9.1 is driven in the direction of rotation 10 by the spindle motor 20.1.
  • the second winding spindle 9.2 with the sleeve 7 clamped thereon is in the waiting position.
  • the auxiliary thread guide 11, which will be described later, is also still in the waiting position.
  • the coils can also be driven by the deflecting roller.
  • the deflection roller lies on the surface of the spool and is driven at a constant speed.
  • the traversing device also includes the deflection roller 21, which is partially wrapped around by the thread 6 and which either rests on the spool or only a very small one with the spool Gap forms, so that the drag length L1 of the thread between the deflection roller and the bobbin is very small.
  • the traversing devices are mounted on a carriage 22 that is movable in the vertical direction and sketched in FIG. 2. Details of the traversing device shown result, for example, from DE-PS 20 40 479 and 23 45 898. However, it is only an example. Other types of traversing devices are also conceivable, cf. for example EP 114 642 (EP-1321).
  • the center distance between the deflection roller 21 and the full bobbin is first increased for the purpose of changing the bobbin, so that the deflection roller 21 completely releases the full bobbin 8.1.
  • the carrier 18 - as shown in FIG. 4 - is rotated in the direction of movement 24 until the winding spindle 9.2 with the empty tube 7.2 stretched thereon gets into the thread path.
  • the laying stroke H which is predetermined by the traversing stroke CH of the thread guide 3, ie the spool length is reduced to the laying stroke H2.
  • This reduced laying stroke H2 makes it possible to axially shift the winding spindle 9.1 with the direction of movement 15 by the amount A without the thread still located in the traversing device falling off the surface of the bobbin.
  • winding spindle 9.2 with the empty tube 7 remains in its original position when the thread is changed, that is to say is not axially displaced.
  • the winding spindle 9.1 is axially displaced in the direction 15 such that, for example, the left end face of the full bobbin 8.1 approximately coincides with the left end of the shortened laying stroke.
  • the axial displacement of the winding spindle 9.1 creates a distance B between the right end face of the full cheese 8 and the right end face of the new laying stroke H2, B being greater than h but less than 2h.
  • the movement length C of the auxiliary thread guide 11 over the right edge of the normal laying stroke H - indicated on the chuck 9.2 in dashed lines - is accordingly greater or at most equal to the distance that the catch slot 17 has from the right end of the normal laying stroke H.
  • the movement length C is less than the amount A of the axial displacement of the winding spindle 9.1. This ensures that - as shown in Fig. 1 - the thread can be brought into the normal plane of the catch slot, but also does not fall off the circumference of the full bobbin 8 and is still wound onto the full bobbin during the catch and through the full coil is promoted.
  • Fig. 6 it is shown that the carriage 22 is now lowered again.
  • the drive can also take place during winding, that is to say in normal operation, by a drive roller 20 which is driven at a constant circumferential speed and which is fastened on the carriage 22.
  • the drive motors 20.1, 20.2 are switched off during normal winding operation.
  • FIGS. 7 to 9 show speed diagrams of the bobbin change. The process sequences proposed according to this invention are described on the basis of these speed diagrams.
  • the spool change according to this invention begins in phase III with the traversing speed steadily falling to a fraction of its setpoint, i.e. the value that the traversing speed at the end of the winding travel, i.e. at the end of phase II, preferably is reduced by more than half.
  • Phase III is initiated by the fact that - as shown in FIG. 3 - the carriage 22 is first raised and thus turned on sufficient distance between the deflection roller 21 and the full reel 8.1 is produced. With the strong reduction in the traversing speed which now begins, the rotation of the carrier 18 takes place at the same time, so that the distance between the deflecting roller 21 and the full reel 8.1 - as shown in FIGS. 4, 5 - increases increasingly. This also increases the drag length between the deflection roller 21 and the full bobbin and thus tends to reduce the length of the thread on the bobbin. This reduction in the laying length compensates for the increase in the laying length that occurs due to the reduction in the traversing speed and is so great that the stroke shortening 2h explained with reference to FIG. 1 also occurs.
  • This greatly reduced traversing speed can then be maintained for a short time in phase IV.
  • the traversing speed is completely suspended.
  • the traversing is suspended, as described above, by the thread being folded over by the auxiliary thread guide in the manner shown in FIG. 5 Phase of the bobbin change is lifted out of the traversing thread guide 3.
  • the thread is now placed on the empty tube 7 on the winding spindle 9.2 by axial movement of the auxiliary thread guide - as explained with reference to FIG. 1.
