The winding device consists of the traversing device 1 with reciprocating thread shaft 2 and traversing thread guide 3. The traversing thread guide 3 is in the grooves 4 the reciprocating thread shaft back and forth and guided straight in the straight guide 5. Through the traversing thread guide 3 the thread 6 is laid on the sleeve 7 to form a cheese 8. The sleeve 7 is fixed on the winding spindle 9.1 stretched. The winding spindle 9.1 is driven with the direction of rotation 10 in a manner not shown. While the winding process a is the second winding spindle 9.2 with the sleeve 7 clamped thereon in waiting position. There is also the auxiliary thread guide 11, which will be described later, still in waiting position.

After or shortly before the end of the winding process, i.e. when the bobbin 8 is almost full, the winding spindle will turn moved away from the traversing device with direction of movement 12, such that the drag length L1 is between Traversing thread guide 5 and the approach line 13 of the thread on the spool to the towing length L2 enlarged. Synchronously with this, the winding spindle 9.2 is clamped with the Empty tube 7 in the direction of arrow 14 in the plane of the thread path in the final state shown in FIG emotional.

By increasing the drag length from L1 to L2, the length caused by the traversing stroke H of the thread guide 5 Predefined laying stroke H, i.e. the coil length reduced to the laying stroke H2. This reduced laying stroke H2 makes it possible to move the winding spindle 9.1 with direction of movement 15 by the amount A,

Normal plane of the catching slot can be brought, but does not fall down from the circumference of the full bobbin 8 and is also wound onto the full bobbin during the catching and is conveyed through the full bobbin.

4 to 8 show the sequence of process steps for changing the bobbin on a winding device, as shown essentially in DE-PS 21 10 367, for example. On a carrier sketched in FIG 18, which is rotatable about the axis of rotation 19, the winding spindles 9.1 and 9.2 are freely rotatable and cantilever stored. In addition, each winding spindle can be engaged and disengaged with one - not shown here Provided auxiliary drive. The bobbins 8 formed on the winding spindles 9.1 and 9.2 are moved by the drive roller 20 powered. The traversing device consists on the one hand of a reciprocating thread shaft 2 and a traversing thread guide 3 (as described with reference to FIGS. 1 to 3) and furthermore from the grooved roller 21 around which the thread 6 wraps. The traversing devices and the drive roller 20 are on a movable in the vertical direction - in Fig. Sketched carriage 22 attached. Details of the illustrated traversing device result e.g.

from DE-PS 20 40 479 and 23 45 898.

with the empty tube 7.2 stretched on it gets into the thread run. As a result, the towing length L2 is between the point of departure of the thread 6 from the grooved roller and the point of contact of the thread on the full bobbin 8.1 has been increased and the relocation stroke H2 has been reduced accordingly. By reducing the wrap angle the grooved roller 21 when moving away the full bobbin 8 is also caused that the thread in the Reversal areas fall out of the reversing grooves, which further shortens the laying stroke results. The winding spindle 9.1 is now - as described with reference to FIGS. 2 and 3 - with direction 15 in such a way axially displaced so that e.g. the left end face of the full bobbin 8.1 is approximately shortened with the left end of the Laying stroke H2 coincides. The thread 6 is now guided by auxiliary thread guides 11 with the direction of movement 25 lifted out of the traversing thread guide 3 and the grooves 21 and into the normal plane in which the thread catching device on the winding spindle 9.2, or something

beyond that.

For textile threads, the catching device is preferably attached as a slot 17 on the circumference of the sleeve 7 and is located slightly outside of the winding area H. In the area of the normal plane in which this slot is located, the auxiliary thread guide leads 11 exerts a very slow axial movement so that the thread is safely caught. Now becomes the auxiliary thread guide 11 driven back into the range of the normal traversing stroke at high speed, so that - like 3 results - between the catch slot 17 and the right end side of the normal winding area H only a few turns of a thread reserve 26 applied

will. As soon as the auxiliary thread guide 11 has reached the traversing area CH again, it is returned to its starting position so that the thread is caught again by the traversing devices and laid to form a cheese. The winding spindle 9.2 or the empty tube 7 clamped thereon is brought back into contact with the drive roller 20 in that the carriage 22 is moved back into its starting position and the carrier 18 is rotated further accordingly. The operating position for the winding spindle 9.2 is shown in FIG.

It should be noted that the changing process happened so quickly It can be that the full bobbin 8.1 does not need any further drive due to its own inertia forces (see above in DE-PS 21 10 367). Of course, however, an auxiliary drive can also be provided which is mounted on the carrier 18 sits. Two auxiliary drives are preferably arranged here on the carrier, one for each winding spindle. The winding spindles 9.2 and 9.1 are like this in this version before and during the thread transfer by their auxiliary drives driven that their surface speed corresponds essentially to the thread speed or something above it.

The auxiliary thread guide 11 according to the invention in the winding device according to FIGS. 4 to 8 can be designed as shown in FIGS. 1 to 3. The construction of such an auxiliary thread guide 11 shown with reference to FIGS. 9 to 11 is characterized by a particularly reliable function. . The preferred embodiment shown in Figure 9 consists of a finger 30 and a displaceable parallel to plate 31. The finger _30: sitting on a pipe 32, ie in the direction of movement 48 "

can be moved parallel to the winding spindle . For this purpose, the tube 32 has a collar designed as a piston 33, which can be acted upon with compressed air in the cylinder 34 through lines 36 or 37. In the tube 32, the rod 43 can be moved with the direction of movement 49 relative to the tube 32 . For this purpose, the end of the rod 43 has a piston 44 designed as a collar. Compressed air can be applied to this in the cylinder 45 through lines 46 or 47. The cylinder 45 is a component part of the tube 32. This has the effect that the rod 43 executes a movement relative to the tube 32 by the application of compressed air to the cylinder 45. The plate 31 is in a straight guide 38 - that is a radial slot in the tube 32 - guided straight with the direction of movement 39 and lies in a recess 42 of the rod 43. The plate 31 is connected to the rod 43 by means of pin 40 and link guide 41 in this way that the plate 31 executes the parallel movement 39 to the finger 30 when there is a relative movement between the tube 32 and the rod 43 with the direction of movement 49.

FIG. 10 shows various functions of the auxiliary thread guide 11 shown in FIG. 9 to illustrate the function Phases of its function. The line 50 represents the end of the stroke of the traversing movement or the end of the bobbin and Slit 51 represents the thread catching slit on the sleeve 52. The thread reserve winding is denoted by 53.

In phase A, the thread guide 11 is in the rest position outside of the traverse stroke CH. The thread 6 is in the traversing thread guide 3 or - with reference to FIGS. 4 to 8 in addition guided back and forth in the grooves of a grooved roller 21.

In phase E, the plate 31 is behind the bottom of the thread guide slot 56 withdrawn so that the thread is due to its own thread tension in the traversing area CH moved back and there again by the self-locking thread guide 3 or the grooves of the grooved roller is caught and laid to a spool with spool length H.

The thread has a few turns for a thread reserve winding 53 formed.

For this purpose, the piston 44 is acted upon by line 47, while the piston 33 is acted upon by pressure through line 37 remain.

In phase F, the auxiliary thread guide moves back to its starting position, the plate 31 initially being withdrawn remain. For this purpose, the piston 33 is pressurized through line 36, while the piston 44 through line 47 remains pressurized. Now the plate is extended again, which is done by the piston is pressurized through line 46.

In Fig. 11 is the function of the auxiliary thread guide according to the invention 11 shows a winding device in which the catch slot 51 is located on the sleeve 52 is located within the traversing stroke CH or the winding area H. It should be noted that in such a winder an axial displacement of the winding spindle is not required.

In phase A, the auxiliary thread guide 11 is in its rest position, while the thread 6 is in the traversing thread guide 3 or - in a winding device according to FIGS. 4 to 8 - also oscillates in the grooves of a grooved roller is and thereby sweeps a substantially vertical thread path plane 57.

In phase B, the auxiliary thread guide is moved into the traversing stroke CH. The thread slides on the run-up slope 54 up and is thereby lifted out of the traversing thread guide 3 and in the thread guide slot caught between finger 30 and plate 31. For this purpose, in the exemplary embodiment according to FIG. 9, the piston 33 pressurized via line 37, while piston 44 is pressurized via line 46.

In phase C, the auxiliary thread guide is guided at a very low speed through the normal plane in which the catching slot 51 lies, until the thread is caught and wound onto the sleeve 52. The auxiliary thread guide now moves at rapid traverse to area 55, where the binding bead is formed by briefly stopping (phase D).
For phases B, C and D, the piston 33 is acted upon by line 36 with different and increasing pressures.

The thread then moves quickly over the area 53 where a so-called thread reserve winding of a few turns is laid. For this purpose, the piston 33 is through line 37 pressurized. In phase E, the auxiliary thread guide stops outside the traversing area CH. The plate 31 is behind the base 58 of the thread guide slot

withdrawn. As a result of its own thread tension, the thread moves into the traversing area CH, where it is captured by the thread guide 3 or the grooves of a grooved roller. For this purpose, the piston 44 is through line 47 pressurized. In phase F the auxiliary thread guide moves 'Return to its rest position by applying pressure to the piston 33 via line 36. Then will Piston 44 pressurized through line 46 and thereby the plate 31 is brought back into the position shown in phase A.

As based on the flow diagrams according to Figures 10 and has been shown, the auxiliary thread guide 11 can after this Invention advantageous for changing bobbins when winding a running thread are used to lift the thread out of the traversing device and on the Tube - in the winding area or outside the winding area - to catch and a thread reserve winding of to form a few turns. This is preferably a method in which the bobbin is changed - on completion of a bobbin - an empty tube clamped on a waiting bobbin spindle is used is pivoted in accordance with the preceding description of FIGS. 1 to 3 and 4 to 8 in the thread path and continues to take up the incoming thread without thread loss.
