Definitions

  • the invention relates to a method and device for producing a thread according to the centrifugal spinning method, in which the thread is deposited as a cake on the inner wall of a spinning centrifuge and then rewound onto a sleeve inserted into the spinning centrifuge.
  • the thread turns are regularly distributed along the inner wall of the spinning centrifuge with the help of a thread guide.
  • the invention has for its object to form a flyer winding when rewinding on a sleeve and at the same time to facilitate the absorption of the thread end from the spinning cake on the occasion of the removal of a thread break.
  • this object is achieved in that the cake is built up on the inner wall of the spinning centrifuge in layers which, with increasing cake thickness, overlap each other at their ends, by starting from an initial stroke of a thread guide which effects the depositing of the thread in the spinning centrifuge Stroke is increased with increasing cake thickness.
  • a flyer winding with a layer-by-layer construction automatically results, with which the layer length decreases with increasing winding thickness. If the thread breaks, the end of the thread is easy to find because it must always be in the outermost layer of the cake and because the outermost layer covers all other layers.
  • the stroke of the thread guide is advantageously shifted such that the increase in stroke per layer is at least one, preferably at least two thread thicknesses. In particular, this is to ensure that underlying layers are covered securely and the flanks of the cake are not too steep.
  • the last layer of the cake is advantageously ended on the inner wall of the spinning centrifuge. From there the transition of the thread onto the sleeve of the bobbin then takes place during the winding.
  • a new and inventive device suitable for carrying out the method is characterized in that a thread guide connected to an automatic control device is used to deposit the thread in the spinning centrifuge is provided and that the control device is arranged, set up and / or programmed or regulated in such a way that the thread guide executes reciprocating lifting movements in the axial direction of the spinning turbine, the stroke length of which increases with increasing cake thickness.
  • the thread guide and / or its control device is advantageously arranged, set up and / or programmed or regulated in such a way that, starting from an initial stroke length, the stroke length increases to both sides of the initial stroke length, either simultaneously or alternately from one stroke length to another and to the other side of the initial stroke length.
  • the device 1 for producing a thread 2 has, among other things, a drafting device 3 in which roving or fiber sliver 4 is stretched to form a fiber ribbon 5.
  • the fiber ribbon 5 passes through a tubular thread guide 6 into a pot-like spinning turbine 7, on the inner wall 8 of which the fiber ribbon 5 turned into a thread 2 is placed as a cake 9.
  • Fig. 1 shows in section that, for example, the outermost layer 10 covers all other layers. Accordingly, the layer immediately below layer 10 covers all other layers and so on.
  • a machine frame 11 carries a motor 12 and the hydraulic actuating cylinder 13 of a control device 14, for example.
  • the piston rod 15 of the actuating cylinder 13 carries a thread guide bench 16.
  • the thread guide 6 and possibly further thread guides of other spinning devices are attached to the thread guide bench 16.
  • the hollow shaft 17 of the electric motor 12 is connected to the spinning turbine 7.
  • the thread guide 6 While the motor 12 rotates the spinning turbine 7, the thread guide 6 does not take part in the rotary movement. It is mounted or guided in the hollow shaft 17 or in the centrally pierced spin turbine 7 either by plain bearings, roller bearings or without direct contact in such a way that it can be moved in the vertical direction by moving the thread guide bench 16 up and down.
  • the control device 14 is a control device of a conventional type, which operates automatically, for example according to the diagram 18, which is set up and / or programmed or regulated with the aid of setpoint transmitters 19, 20, 21 in such a way that the thread guide 6 in the axial direction of the spinning turbine 7
  • it carries out reciprocating stroke movements, the stroke length of which increases with time and thus also with increasing cake thickness.
  • the diagram 18 shows that the stroke length h, starting from an initial stroke length corresponding to the limit curves 22 and 23, increases on both sides of the initial stroke length, approximately symmetrically to the center line m with increasing spinning time t.
  • control device 14 is set up and / or programmed or regulated in such a way that the speed of the lifting movement of the thread guide 6 takes place as a function of the thread thickness that can be set on the setpoint device 19 and at the same time as a function of the thread depositing speed or turbine speed that can be set on the setpoint device 20.
  • the speed of the lifting movement can therefore be set up in such a way that thread layers according to FIG. 3 build up, in which thread lies next to thread.
  • the stroke is increased from layer to layer in such a way that the stroke increase per layer is three thread thicknesses.
  • the beginning of the first layer is 24 and the end of the last or uppermost layer is 25.
  • the further layers lying above the first layer are each stepped, but in practice the steps are smooth and not as clear or visually are not visible at all, especially since textile threads are generally much thinner than Fig. 3 shows greatly enlarged on a simple winding structure.
  • the desired number of positions which is synonymous with the desired number of lifting movements, can be set on the setpoint generator 21.
  • the mouth 26 of the thread guide 6 then remains in an end position.
  • the motor 12 Before the cake 9 is formed, the motor 12 already rotates the spinning turbine 7.
  • the mouth 26 of the thread guide 6 is first brought into the starting position by correspondingly moving the thread guide 16.
  • the end of the thread 2 protruding from the thread guide 6 is brought against the inner wall 8 of the spinning turbine 7 (FIG. 3) in a conventional manner after the drafting device 3 has been switched on, at point 24.
  • the mouth 26 moves through the control device 14 automatically controlled, first down until the lowest layer is completed. This position is symmetrical to the center line m.
  • the thread guide 6 moves upward without stopping until the mouth 26 is at a height which extends three thread thicknesses beyond the start 24 of the first position.
  • the mouth 26 then moves down again until it comes to a height that is three thread thicknesses below the lower end of the first layer. This scheme continues until the winding or cake 9 is completed.
  • the drafting system 3 is now stopped and the thread guide 6 is possibly moved into the upper end position.
  • a sleeve 27 is inserted centrally into the spinning turbine 7 by hand or by an automatic device.
  • the thread 2 lies against the surface of the sleeve 27 or is brought onto the sleeve, whereupon the thread of the cake 9 unwinds automatically onto the sleeve 27 while the spinning turbine is running.
  • a winding is formed in the manner of a flyer coil, in which all layers are concentric and where each newly formed layer is shorter than the previous one.
  • the envelope curve of the flyer winding is shown in dash-dot lines in FIG. 2 and is designated by 28.
  • the sleeve 27 provided with the winding 28 is then removed from the spinning turbine 7 and the thread guide 6 can now be moved back into its starting position, whereupon the formation of the cake 9 is repeated.
  • the drafting system 3 is started each time.
  • each subsequent layer according to FIG. 3 takes a certain time longer than the formation of the previous layer, the limit curves 22 and 23 of the diagram 18 have a straight course.
  • another winding structure is also conceivable, in which the limit curves have a curved course if, for example, the cake 9 is to have either concave or convex end sections.
  • the winding structure indicated in FIG. 3 is then modified.
  • the thread guide bench 16 can alternatively go over the entire machine side of a spinning machine and, for example, be carried at both ends by actuating cylinders 13 connected to the control device 14 or moved up and down. Instead of using actuating cylinders, the up and down movement can also be accomplished by means of gears, as are known on ring spinning machines for moving the ring bench.
  • the motor 12 is at the bottom and the open side of the spinning turbine 7 is at the top.
  • This training would have the advantage, inter alia, that the sleeve 27 could be placed on the thread guide 6 before the start of spinning and the shaft of the motor would not have to be hollow.
