Definitions

  • the invention relates to a method for wrapping a Spun package according to the preamble of claim 1 and an apparatus for performing the method.
  • Pot spinning is usually carried out in the spinning centrifuge or the thread in the spin pot as a spin cake Completion of the actual spinning process on a previous one inserted sleeve wrapped so that a spinning cop is created.
  • an empty sleeve is used, which during the actual Spinning process held ready on the thread guide tube and to Initiate the wrapping process on the Spinning centrifuge inner wall of deposited package over the Muzzle of the thread guide tube is lowered.
  • the edge of the sleeve detects that from the thread guide tube emerging rotating yarn legs, for example in an am lower end of the sleeve arranged slot, and prevents it by further rotation with the result that the at the The inner wall of the spinning centrifuge is deposited and continues with it rotating twine wraps around the core and thus on the empty tube is rewound.
  • thread attached forms a drag thread or With the free end, e.g. one can be half a meter long, at the spinning station or at the further handling of the sleeve or the spinning cop disruptive Act.
  • the object of the invention is to identify sources of interference on a Eliminate pot spinning machine.
  • the separation is preferably carried out as a shear process, targeted, clean and safe separation is possible.
  • the Thread does not break accidentally e.g. at a thin point under Leaving a still disturbing thread remnant or free End.
  • the separation is preferably carried out when the thread is on one end of the drafting rollers and at the other end of Spool or the sleeve is held and tensioned, as in the Period between the start of the wrapping process and the Detachment of the thread from the drafting system is the case. The severing is therefore possible without additional clamping devices.
  • the Thread is at both ends at the time of the shearing process sufficiently fixed and tense.
  • the separation is preferably carried out by the Rotational movement of a separating device, its axis of rotation on the common longitudinal axis of the sleeve and thread guide tube imaginary center line. This allows one Particularly reliable and targeted separation directly on the Slot of the sleeve.
  • the preferably suction through the Match extraction takes place by using the at the spinning position existing suction a simple and effective Suction possibility.
  • each spinning station has one Separating device for separating the remainder of the filament from Package and a suction device for removing the sun separated filament residue. So it is possible at Start of wrapping and thus when the remnant of spun thread arises to remove it immediately.
  • the separating device preferably at least one in the axial direction of the sleeve movable knife and preferably at least one by one Rotation axis rotatable knife, the rotation axis on which is the common longitudinal axis of the sleeve and thread guide tube imaginary center line.
  • the knife is advantageously crown-shaped.
  • the device for Pot spiders Means for converting the axial relative movement of Thread guide tube and sleeve in the knife movement, the Means in particular from an at least partially helical running groove and a movable bolt in the groove consist.
  • At least one Separating device for separating the remainder of the filament on one Wanderdoffer arranged, and the Dofferabsaugung is also as Suction device designed for the remainder of the spun thread.
  • the spinning station of a pot spinning machine shown in Fig. 1 lies in the fiber flow direction below one through the last Delivery roller pair indicated drafting system 1.
  • the in Drafting device 1 warped sliver 2 is in the spinning triangle 3 under the effect of the rotating spinning centrifuge 4 into a thread 5 twisted together and by as part of a thread guide formed thread guide tube 6 into the spinning centrifuge 4 introduced.
  • From the mouth 7 of the thread guide tube 6 emerging thread 5 lies under the action of the rotation the spinning centrifuge 4 to the inner wall 8 of the spinning centrifuge 4 and forms a package 9 there.
  • the thread guide tube 6 leads one in the axial direction through the double arrow indicated oscillation movement with which the formation of the Package 9 is controlled.
  • the position that the Thread guide tube 6 in Fig. 1 and during the traversing movement occupies is called the spinning position.
  • the spinning process is via the thread guide tube 6 pushed sleeve 10 above the mouth 7 of Thread guide tube 6.
  • the sleeve 10 is on the Mouth 7 of the thread guide tube 6 into the dashed drawn rewind position 11 lowered.
  • the circulating Yarn leg 12 is a slot 13 at the foot of the sleeve 10th detected and fixed so that the package 9 automatically on the Sleeve 10 wrapped with spinning centrifuge 4 rotating further becomes.
  • the wound sleeve 10 can then on a held ready below the spinning centrifuge 4 Transport plate 14 applied and together with the Transport plate 14 are removed for further processing.
  • the end of the filament thread 15 remains on the sleeve 10 fixed and can with the other loose end at the spinning position, in the event of removal or further processing for faults to lead.
  • Fig. 3 shows a part of the thread guide tube 6, the the lower end protrudes into the spinning centrifuge 4.
  • the Thread guide tube 6 is in a guide 17 in the axial direction kept slidable.
  • the sleeve 10 is during the Spinning process by means of a bracket 16 detachable connection fixed in position.
  • the tour 17 is arranged inside the sleeve 10 and in the holder 16 about the center line 18 coinciding with the longitudinal axis rotatably mounted.
  • the guide 17 is in the axial direction not displaceable relative to the holder 16.
  • the mouth 7 of the thread guide tube 6 extends beyond the end of the Sleeve 10 addition, and the twine leg 12 can be freely rotate.
  • the knife 19 In the lower part of the sleeve 10 is fixed to the guide 17th connected knife 19 arranged.
  • the knife 19 is in one in turn, its counterpart 20 firmly connected to the sleeve guided.
  • the knife 19 is crown-shaped at its lower end trained and can with the prongs 21 of the crown-shaped part in the counterpart 20 a rotational movement around the Execute center axis 18.
  • the detail X of FIG. 3 is in 4 is shown enlarged.
  • the thread guide tube 6 has one in the lower part parallel to the center line 18 extending groove 22 on the lower end of the thread guide tube 6 is too helical is trained.
  • the wrapping process is initiated in that the sleeve 10th lowered over the mouth 7 of the thread guide tube 6 becomes. If the lower edge of the sleeve 10 the circumferential Twine legs 12 reached, this is captured by the slot 13 and fixed. The wrapping process starts automatically through the further rotating spinning centrifuge 4.
  • the rewinding position 11 of the sleeve 10 is shown in FIG. 5.
  • the sleeve 10 has its position in relation to the thread guide tube 6 together with the bracket 16 and the guide 17 together with the attached to the guide 17 knife 19 and the Sleeve 10 attached counterpart 20 in the axial direction changed.
  • the bolt 23 also has its position around the Corresponding way down changed. Thread guide tube 6 and sleeve 10 are held so that both do not perform a rotational movement about the center line 18.
  • Doffing can also be done in a random order done by a hiking suitcase 26.
  • the principle representation 7 shows a hiking suitcase 26, the one Cutting device 27, a suction device 28 and a Gripping device 29 for pulling the wound sleeve 10 and for attaching a sleeve 10 held ready as an empty sleeve having.
  • the gripping device 29 grips the foot of the wound Sleeve 10
  • the suction device 28 sucks the spun thread residue 15, which is now detached from the sliver 2 at the spinning triangle 3 has, and the cutting device 27 separates the Spider thread residue 15 directly at the foot of the wound sleeve 10.
  • the knife 19 can also be in direct cooperation with the Slit 13 of the sleeve 10 shear off the remaining filament 15, wherein the slot 13 acts as a notch 24 of the counterpart 20.
