Definitions
- the invention relates to a winding machine for winding a continuously starting thread according to the preamble of claim 1.
- Such a winding machine is known from EP 0 677 019 (Bag. 2058).
- the thread is moved back and forth along a predetermined traversing stroke by means of a traversing device transversely to the thread running direction.
- the traversing device is designed as wing traversing. It is therefore necessary for the thread to be guided out of the traversing plane by means of a guide edge of a guide ruler in order to equalize the traversing speed over the entire traversing stroke. This compensates for the differences in thread guide speed of the wing.
- the known winding machine in the stroke end regions each has an auxiliary guide which penetrate the traversing plane with its counter-guide edges in such a way that the thread is deflected in opposite directions.
- the auxiliary guide rule can be moved transversely to the traversing plane in such a way that the counter-guide edge penetrates the traversing plane less or not.
- the thread is thus guided through the wing in the partial area between a transition point and the stroke reversal point.
- the transition point is the position in which the leading edge of the main guideline penetrates the traversing plane, so that the leading edge extends outside the traversing plane in the partial area up to the traversing stroke end.
- the thread comes loose from the leading edge of the main guide at the transition point.
- the advantage of the invention lies in the fact that the thread slides down from the leading wing tip before the stroke reversal point is reached due to the missing counter-guide edge. On the one hand, this shortens the stroke and, on the other hand, it prevents the thread tension from collapsing alternately during the winding, so that incorrect windings, for example by the so-called stripper on the full bobbin, are avoided.
- the winding machine according to the invention has the advantage that when changing the thread can be taken over with a high degree of certainty from the thread catching element, since the thread is only guided through the wing and is therefore offered repeatedly to the catching element.
- the development according to claim 2 has the advantage that the towing length of the thread is almost constant.
- the drag length is defined as the length between the leading edge of the guide ruler and the run-up point on the pressure roller. An exact length of the traversing stroke is thus maintained.
- the arrangement of the main guide and the auxiliary guide according to claim 3 is particularly advantageous for the operation and application of the thread.
- the embodiment according to claim 4 represents a particularly cheap and simple design of the main guide.
- a further particularly advantageous development according to claim 5 provides that a thread catching element is arranged adjacent to the auxiliary guide, which element can be moved into the stroke end region of the traversing stroke in order to take over the thread from the traversing.
- the thread catching element is positioned in such a way that the caught thread does not run directly onto the full bobbin in the vicinity of the reversal point. The thread is thus still safely placed on the bobbin.
- the thread catching element is designed according to claim 6. As a result, the thread is guided directly into the catch slot of the thread catch element by means of the traversing. The looping of the thread on the catch guide edge has the effect that no significant thread tension fluctuations occur until the thread is caught.
- the opposite guide edge is used to free the thread from the catch slot of the catch lock.
- the embodiment according to claim 10 is particularly advantageous in order to obtain reproducible wrap angles at the leading edges with each winding.
- the development of the winding machine according to claim 11 is advantageous, especially when changing the bobbin, since the movement sequences between the thread catching element and the movable partial guide can be combined in a simple manner.
- the winding machine In order to change the traverse stroke length during the formation of the bobbin and thus to realize a so-called breathing, the winding machine can advantageously be implemented.
- FIG. 1 shows the front view of a winding machine according to the invention
- FIG. 2 and 3 show the side view of the winding machine from FIG. 1 with different thread positions along the traversing stroke
- FIGS. 6 and 7 show a further exemplary embodiment of a traversing device with an auxiliary guide rule consisting of a movable and a fixed partial guide rule;
- Fig. 8 shows another embodiment of a winding machine in the change phase when turning the thread.
- the traversing device is designed as wing traversing, as is known from EP 0 114 642 (Bag. 1321) and is described there in detail.
- the wing traversing device consists of the wings 6 and 7, which are driven in opposite directions by the traversing drive 5.
- the main guide 8 is arranged in a plane parallel to the wings 6 and 7.
- the auxiliary guide 9 is arranged opposite the main guide 8.
- the auxiliary guide 9 is connected to a linear drive 10.
- the thread catching element 11 with the carrier 12 attached to a linear guide 13.
- the linear guide 13 is moved in the direction of movement 33 by means of the drive 14.
- a pressure roller 4 is rotatably mounted on a rocker 39 in the machine frame 19.
- the pressure roller 4 lies on the coil surface of the coil 3 with a predetermined contact pressure.
- the coil 3 is formed on a sleeve 15.1.
- the sleeve 15.1 is clamped on a winding spindle 16.1.
- the winding spindle 16.1 is driven by the spindle motor 17.1.
- the spindle speed is regulated in such a way that the peripheral speed of the coil remains constant during winding. For this purpose, the speed of the pressure roller is measured.
- the winding spindle 16.1 is mounted on a turret 18.
- a second spindle 16.2 is arranged on the turret 18 offset by 180 ° with respect to the spindle 16.1.
- the empty tube 15.2 is clamped on the winding spindle 16.2.
- the thread 2 is supplied without interruption at a constant speed.
- the thread 2 is first passed through the head thread guide 1, which forms the tip of the traversing triangle.
- the thread then enters the wing traversing device. It has blades 6 and 7, which are attached to two rotors (not shown here).
- the rotors rotate in different directions of rotation and drive the wings in such a way that the thread is guided alternately on the leading edges of the main guide and the auxiliary guide, one wing taking over the guide in one direction and then dipping under the guide, while the other wings take the lead in the other direction and then dive under the ruler.
- the thread on the pressure roller 4 is deflected at more than 90 ° and then wound on the bobbin 3.
- the coil 3 is formed on the sleeve 15.1.
- the sleeve 15.1 is clamped on the freely rotatable winding spindle 16.1.
- the winding spindle 16.1 is located on it on the stretched sleeve 15.1 in the operating position.
- the second winding spindle 16.2 is in a waiting position.
- the winding spindles 16.1 and 16.2 are pivoted by means of the turret 18 such that the winding spindle 16.2 engages with the empty tubes 15.2 in the thread course. The sequence of movements for this will be described later
- FIGS. 2 and 3 show the side view of the winding machine with different thread positions along the traversing stroke.
- the traversing device is represented by the rotors 22 and 23, the wing 7 being arranged on the rotor 22 and the wing 6 being arranged on the rotor 23.
- the rotors 22 and 23 are arranged such that the vanes 6 and 7 rotate in two closely adjacent, mutually parallel planes of rotation.
- the traversing plane 21 is stretched between the top thread guide 1 and the pressure roller 4.
- FIG. 3 shows a schematic plan view of a traversing device with a main guide and auxiliary guide.
- the main guide ruler 8 is fastened on the drive side of the traversing device in such a way that its leading edge 28 penetrates the traversing plane 21 at the transition points 24.
- the thread 2 with the wings of the traversing device is guided along the guiding edge 28 within the traversing stroke ⁇ between the transition points - that is to say in the central region.
- the auxiliary guide ruler 9 is arranged opposite the main ruler 8.
- the auxiliary guide 9 has a counter-guide edge 29 which penetrate the traversing plane 21 in the immediate vicinity of the transition points 24 in the direction of the drive side.
- the counter-guide edge 29 of the auxiliary guide 9 extends beyond the stroke reversal points. It is thereby achieved that as soon as the thread 2 has passed the transition point 24 when guided along the guide edge 28, the thread deviates from the guide edge 28 to the counter-guide edge 29 when it passes through the traversing plane.
- the thread is then guided in the area between the transfer point 24 and the reversal point 25 on the counter-guide edge 29.
- the thread-guiding wing emerges under the main guide and the non-thread-guiding wing takes over the thread.
- the traversing stroke is thus advantageously influenced.
- the thread placement on the bobbin to be formed can thus be influenced in such a way that hard bobbin edges and saddle formation on the bobbin are avoided.
- the thread guide In the operating position of the auxiliary guide 9, the thread guide accordingly runs in such a way that the thread is guided along the leading edge 28 of the main guide 8 in the central region of the traversing stroke.
- the Middle area characterized by the area between the transition points 24. Outside the middle area in the adjacent sub-areas, the thread is guided between the transition point 24 and the stroke reversal point 25 on the counter-guide edge 29.
- the auxiliary guide 9 If the auxiliary guide 9 is now moved in the direction of movement 32 essentially perpendicular to the traversing plane by means of the linear drive 10, the thread detaches from the leading edge 28 of the main guide 8 upon entry into a sub-region of the traversing stroke adjacent to the central region. The thread is now only guided by the leading one Wing led.
- the auxiliary guide ruler 9 with its counter-guide edge 29 is arranged on the opposite side to the guide ruler 8 with the guide edge 28.
- the auxiliary guide 9 is moved by means of the linear drive 10 in such a way that the distance between the guide edge 28 and the counter-guide edge 29 increases, so that thread insertion or when changing from a full bobbin to an empty bobbin End thread name is made possible by a thread catching element.
- the auxiliary guide 9 is moved into its operating position by the linear drive.
- the operating position is predetermined by a fixed stop 40.
- the windows 27 are cut in the stroke end areas in the auxiliary guide. There is also an incision in the main guide 8 Window 26 introduced to reduce mass.
- FIG. 5 shows a further exemplary embodiment of a traversing device.
- the structure is very similar to the exemplary embodiment from FIG. 4, and in this respect reference is made to the description of FIG. 4 and the functional description of FIG. 4.
- the auxiliary guide 9 according to the exemplary embodiment according to FIG. 5 is U-shaped.
- the leg ends have a shoulder on which the counter-guide edge 29 is formed in each of the stroke end areas.
- the linear drive 10 provided for the movement of the auxiliary guide acts on the cross strut carrying the legs. This arrangement has the advantage that all drives and thus all connections are on one side of the traversing plane. This is particularly advantageous for the operation and for the thread guidance of the winding machine.
- the auxiliary ruler is divided into two partial rulers 9.1 and 9.2.
- the partial guide ruler has the opposite guide edge 29.1 and the partial guide ruler 9.2 has the opposite edge 29.2.
- the partial guideline 9.2 is fixed to the main guideline.
- the partial guide rule 9.1 is designed to be movable and can be moved by means of the linear drive 10 such that the counter-guide edge 29.1 emerges from the traversing plane. In the case of this arrangement, the same thread course as described previously in the exemplary embodiment in FIG. 4 is described.
- the thread-catching element 11 is arranged in a plane parallel to the partial guide rule 9.1.
- the thread catching element 11 has a catching guide edge 30 which ends in a catching slot 31.
- the thread catching element 11 can be moved in the direction of movement 33 parallel to the traversing plane by means of the linear drive 13.
- the partial guideline is 9.1 movable in the direction of movement 32 transversely to the traversing plane by means of the linear drive 10.
- Fig. 7 the situation is now shown in which the partial guide rule 9.1 is moved perpendicular to the traversing plane, so that the counter-guide edge 29 no longer penetrates the traversing plane 21.
- the thread 2 guided by the wing would not receive any guidance provided in the area between the transition point 24 and the stroke reversal point 25 for deflecting the thread from the traversing plane.
- the thread will fall from the wing tip of the thread-guiding wing before the stroke reversal point 25 is reached.
- the thread catching element 11 assumes a position in the area between the transition point 24 and the stroke reversal point 25. If the thread 2 is now guided by means of the wing 6, the thread will slide in the direction of the catch slot 31 after passing through the transition point along the catch guide edge 30 of the catch lock 11. The thread 2 falls at the end of the catching guide edge 30 into the catching slot 31 of the thread catching element. Here, the thread largely comes out of the reach of the rotating wings. The wing bringing the thread just sweeps over the thread guide edge 30 of the thread catching element for guiding the thread into the catch slot 31. The catch slot 31 is directed so that the thread can dip from the area of the rotating wings in the direction of the traversing plane.
- the thread catching element 11 moves with the thread to the right outside the traversing stroke into a so-called catching position. In this position, the thread is guided over the sleeve catch slot 20 (see FIG. 1) of the new sleeve. When the thread is caught, the catch lock moves to the left again. In this phase, the thread reserve is formed on the new tube. With the movement of the catch lock 11 in the direction of the stroke reversal point, the partial guide rule 9.1 is simultaneously moved into its operating position. Here again, a coordinated movement of the partial guide and the catch lock takes place.
- the retracting mating guide edge 29.1 continuously lifts the thread out of the catch slot 31 of the catch lock 11. Shortly before reaching an exit position of the catch lock, the thread is completely led out of the catch slot 31 and thus returns to the traversing. This output position of the catch lock is only just outside of the traversing stroke, so that the traversing thread cannot touch the thread catching element still standing there.
- the counter-guide edge 29.1 of the partial guide rule 9.1 has now moved completely into its working position. So the thread can be changed normally again.
- the exact coordination of the movements of the partial guide and the catch lock can be done via software-controlled pneumatic switching elements and the separate linear drives 10 and 13 or by means of a changeover gear with only one linear drive.
- the second partial guide rule 9.2 with a drive Mistake.
- This measure allows breathing to a limited extent during the winding cycle.
- the partial guide ruler is moved with the respective counter guide edge out of the traversing plane, so that the thread slides prematurely from the leading wing before the stroke reversal point is reached. The thread is then taken over and returned by the wing rotating in the opposite direction.
- FIGS. 8 shows a further exemplary embodiment of a winding machine in the changing phase.
- This winding machine corresponds essentially to the known winding machine from EP 0 374 536; in this respect reference is also made to this document.
- the thread 2 is lifted out of the traverse by means of a lifting device 34.
- the lifting device is pivotally attached to the pivot axis 35.
- the auxiliary guide 9 is extended so far that the thread can run freely from the lifting device 34 onto the pressure roller 4.
- a pivot lever 36 is pivoted, which guides the thread 2 with a sheet metal 38 such that the thread 2 runs onto the full bobbin 3.
- the lifting device 34 itself or a thread catching element, as shown in FIGS.
- the thread wrap in particular in the area of the stroke reversal, can advantageously be increased such that the leading edge of the main guide and the leading edge of the auxiliary guide overlap.
- the towing length can be varied. It can also be used to set any thread tension.
- the winding machine according to the invention also detects wing swings in which the thread is laid over a traversing stroke by means of a plurality of wings arranged side by side.
