The invention relates to a winding device for threads, Ribbon or the like, whose traversing thread guide with a cam drum Or the like. Are connected and guided in pivotable guide rails via angle levers, which are in their position adjustable by the growing roll diameter on the one hand and by a periodic to-and-fro movement on the other hand are.

In winding devices of this type, it is known to use guide rails to gradually shorten the traversing thread guide stroke, which follow the manner of a two-armed lever are pivotable one point. One end of an angle lever is guided in the guide rail, the other end of which carries the thread guide. The drive for the back and forth movement the angle lever and thus the thread guide acts on the pivot point of the angle lever. The guardrail takes a position which is parallel to the axis of the bobbin, the stroke of the traversing thread guide exactly matches the stroke of the drive device match. However, if the guide rail is inclined to a greater or lesser extent relative to the coil axis, it is superimposed the drive stroke is accompanied by an additional stroke movement

movement that comes about because that in the guardrail guided end of the angle lever due to the inclination of the guardrail in its back and forth movement also up and is discharged. A facility of this type can be installed DRP 655 5O4 used to produce coils with tapered ends when the guardrail has a linkage with the swiveling coil arm connected 1st * and from this with growing Winding diameter is pivoted.

A precision package winder is also from the DBP 969 169 known, in which a link can also be pivoted as a function of the winding diameter, which the shortening the traversing stroke caused during the WiekelVorganges. at However, this device does not require a mechanical connection between the winding support and the link, since the bobbin carrier is arranged in a stationary manner here and the thread guide itself from the bobbin carrier as the winding diameter increases is moved »Here the backdrop of each thread guide is guided with one of its two ends in the slot of a lever, which is stored in the machine frame. In addition, it is from the » known this publication, to avoid so-called hard Edges the traversing stroke a periodically increasing and decreasing stroke change to overlay. For this purpose, the levers of all winding units of a machine are on one over the entire Maschin® attached extending rod, which is periodically reciprocable with a short stroke.

If the winding shape of the coils is to be changed, for example instead of cylindrical coils with conical ends, those with flat ends are produced, or should the characteristic the back and forth movement are changed, the levers or adjusting members of all winding units must be individually be replaced. This is a very time-consuming job, especially in larger machines with many winding units

in addition, they are often not carried out by the operating personnel and which makes extensive spare parts storage necessary.

In this state of the art, the task is "to provide a winding device for threads, tapes or the like of the type described above, in which the changeover from one Wrap shape on the other not by remodeling »but by simple switching can be carried out.

According to the invention this object is achieved in that the Guardrail through a clutch, with which the influence of the growing winding diameter is optionally switched on or off, is connected to their adjusting members. In particular, the clutch can operate in the longitudinal direction of the machine be displaceable curved piece, the working surface of which is arranged in a form-fitting manner between the guide rail and an abutment, the curved piece being used to generate coils can be pushed with flat ends into a position in which it rests against an abutment, the position of which is independent of the winding diameter; or to produce wraps with conical ends can be pushed into another position in which the cam piece rests against an abutment, the position of which depends on the winding diameter. The arrangement is made in each case so that the curve piece in every position can also be moved back and forth periodically by an adjusting member by a small amount.

The arrangement of such a sliding curve piece can now be realized in that the curved piece of each traversing thread guide is arranged on the associated guide rail itself and for the production of laps is slidable with flat ends into a position in which its work surface under spring pressure against a fixed point of the

In Pig. 1, the bobbin 1 is shown on which in the course of the WiekelVorganges the winding 2 is to be built. the Spool tube 1 is supported by spool arms 5 (see also Fig. 5 * 6) worn around the pivot axis 4 with increasing winding diameter can be swiveled out.

The roll 2 is always constant from the distribution roller 5 Driven speed at which it rests loosely. The friction roller 5 in turn is driven via a shaft 6 which preferably extends over the entire length of the machine and common to all distribution rollers 5 on one side of the machine is.

The traversing device 7 is intended to guide the thread to be wound up and to deposit it exactly. It consists of a thread guide 8 which is arranged at one end of an angle lever and is guided back and forth by this in the longitudinal direction of the bobbin. For driving the angle lever 9 engages in the pivot 10, a tab 11 to _# which in turn is guided in the arranged parallel to the coil axis guide rail 12th The slide 11 engages with its slide shoe IJ through a gap in the guide rail 12, the slide shoe 13 engaging in a helical groove V4 of a curve tube 15. Since the rider 11 cannot move perpendicular to the guide rail 12 when the cam drum 15 rotates due to its axially parallel guidance through the guide rail 12, it is guided back and forth by the groove 14 parallel to the surface of the roll 2.

At the other end of the angle lever 9 there is one around the pin 16 rotatable sliding block 17 is arranged, which is guided in the guide groove of a guide rail 18 such that it moves back and forth of the rider 11 can slide back and forth in this. The guardrail 18 in turn is in a bearing support 19 according to

Mounted like a two-armed lever, the pivot point is at 20.

At one end 21 of the guide rail 18, a spring 22 anchored at the machine frame engages, which · pulls the rail with low> * eng downward force.

According to the invention, the curved piece 25 is arranged displaceably on the guide rail 18. The curve piece 23 here encompasses the guide rail 18 in a form-fitting manner. In the back of the curve; In the exemplary embodiment shown, a groove 24 is incorporated into the piece 23, into which a bolt 25 engages, which is firmly connected to the adjusting member 26. The groove 2h is here slightly curved in the shape of a circular arc, which is necessary because of the tilting movement of the guide rail 18 about the pivot point 20.

The cam piece 23 has a Arbeltsfläche 27 _s with which it rests form-locking with the interposition of the translation 28 of the transfer member 29th The already mentioned spring 22 ensures the positive fit of the system. The transmission member 29 can have the shape of a tapering tongue, as can be seen from FIG. It is attached to the spool arm 3 in such a way that it is pivoted outward as the swing length increases in such a way that its contact edge 30 moves back further with respect to the transfer cam 28 because of the aforementioned taper. This has the effect that the guide rail 18 is readjusted under the flow of the spring 22 and consequently changes its position more towards the horizontal. This change in position causes, as already described at the beginning, a shortening of the traversing stroke, so that in this position of the cam piece 23 coils with conical ends are produced.

J »

The transmission cam 28 has the purpose of keeping laterally directed displacement forces away from the transmission member 29, which

0098 4 2/0588

'- 9 - Ba *. 666 I.

otherwise occur because of the inclined position of the work surface 27 would have to. The cam itself is adapted to the course of the working surface 27 on the one hand and the shape of the contact edge 350 on the other hand and it is itself secured against lateral displacement, for example? by means of the leaf spring 31, which is at 32 on the Guard rail 18 is attached.

The arrangement shown also allows a periodically increasing and decreasing edge to be avoided in order to avoid so-called hard edges To superimpose stroke change the traversing stroke. This can be carried out by the adjusting member 26 in a corresponding Rhythm is guided back and forth by a small amount, the inclination of the working surface 27 of the curved piece causes the guardrail 18 to swing up and down.

To produce coils with flat ends, the cam piece 23 can be pushed into a position with the aid of the adjusting member 26 which can be seen from FIG. In this case, the inclined working surface 35 of the curved piece 23 is opposite a fixed point 3 ^, for example, with the machine frame connected bolt can be. In this position of the cam piece 23, the position of the transmission member remains 29 without any influence on the curve piece or the guide rail Back and forth movement of the adjustment member 26 to superimpose a slight breathing movement on the thread guide stroke.

Another embodiment of the device according to the invention is shown in FIG. In this version, the curve piece is 23 is not arranged on the guide rail 18, but on the adjusting member 26. The curve piece can there for example be fastened by means of a screw 35. The work surface 36 acts with the interposition of the transmission cam 28 as well of the transmission link 29 on the guardrail l8 and loading

agrees together with the transmission member 29, the inclined position this rail and thus the length of the traversing stroke. If the adjusting member 26 is periodic by a small amount pushed back and forth, so as a result of the inclination the working surface 36 and the position of the guardrail 18 can be changed slightly periodically, which has the effect that a breathing movement is superimposed on the traversing stroke. For this to have an effect, however, it is necessary that the transmission member 29 is movable in the direction perpendicular to the coil axis at least by a small amount. This can can be achieved in that the tapered tongue is attached to the coil support with the help of a swivel joint, or also simply because this tongue is made of an elastic material, such as polyethylene, polyamide or the like. ' is made.

To switch over the device, the adjusting member 26 be moved to the left, whereby the cam piece 23 by means of its working surface 37 against the approach 38 of the guardrail 18 bumps. As a result, the guardrail is tilted so far that it is outside the area of influence of the transmission link 29 lies. In this position, the winding diameter has no effect on the position of the guide rail 18, so that the winding be made with flat ends. Here, too, by short-stroke back and forth movement of the adjusting member 26 in follow the inclined position of the working surface 37 of the curved piece 23, the position of the guardrail 18 can be changed periodically.

If coils / with conical ends are to be produced with a device of the type according to the invention, it is not absolutely necessary required, the influence of the growing lug diameter • with the help of a tapered tongue that engages the coil arm to transfer this to the position of the guardrail can rather also by other means, for example with

a flexible transmission member 59 in the form of a Bowien cable happen. Such an arrangement is shown in FIGS. The curve piece 25 (Flg. 7) sits in this Fall firmly on the adjusting member 26, which extends over the entire length of the machine. The right-hand end of the guide rail 18 lies under the force of the tension spring 22 on the slide 40 seated driver pin 41 on. Two on the guide rail 12 seated stationary guide pins 42 take over the sliding guidance of the slider 40. The Bowden cable 45 is loose in a stepped bore of the slider 40, in such a way that its end is on the end face 44 of the bore step supports. The Bowden cable core 46 extends through the bore 45, which continues with a smaller diameter End of an elbow 47 is attached. The free leg of the Elbow 47 (Fig. 6) rests on the working surface 48 (Fig. 7) of the curve shape 25, which in turn, as previously described seated firmly on the adjusting member 26 extending over the entire length of the machine. The curve piece 23 has yet another curve edge 49 on. On its the curve piece 25 facing side, the slider 40 has a driver pin 50 (Fig. 6).

A guide sleeve 51 is stationary on the machine frame, not shown attached and has a passage 52, which has any preferably square cross-section Has. A transfer slide 55 is located in the passage 52 out sliding, on which the Bowden cable jacket 43 is supported. A pin 54 seated on the transfer slide 55 protrudes through a slot 55 in the guide sleeve 51 therethrough. The slot 55 extends over the entire length of the guide sleeve 51. The arm 56 of the two-armed transmission lever rests on the pin 54 56, 57 on the other hand rotatable on a pivot bearing 58 is stored. The other arm 57 of the transmission lever 56,57 rests on a stop pin 59 & n # in one of the

Bores 6o of the coil arm 3 is inserted. The transfer rod 53 has a unspecified, longitudinal through bore through which the Bowden cable 46 passed easily movable and at its end by means of a ■ / - on the machine frame fixedly seated clamping device 61 * is secured 62nd

At the beginning of the winding process, the guide rail 18 takes about the a position shown in FIG. The main pivoting movement of the guardrail l8 about the pivot point 20, which reduces the

w tion of the thread guide stroke in the course of the winding process when producing laps with conical ends is also controlled here by the bobbin arm 3, which swings out as the lap increases, and is carried out under the force of the spring 22. The spool arm movement is transmitted (FIG. 6) to the guide rail 18 via the stop pin 59, the transmission lever 57, 56, the Bowden cable casing 43, the slider 40 and the driver pin 41 via the pin 54, the transmission slide 53 *. The Bowden cable core 46, which is held stationary at one end by the clamping device 61, 62, rests at its other end with the angle piece 47 on the working surface 48 of the curve piece 23, and provides the Bowden cable casing 43 with a length-defined support guide between the curve piece 23 and the guide sleeve 51 * so that the contact pressure generated by the spring 22 and transmitted via the guide rail 18, the driver pin 41 and the slider 40 and acting between its end face 44 and the end of the Bowden cable jacket 43 can propagate to the stop pin 59. .

The so-called breathing superimposed on the thread guide stroke goes here again from the adjusting member 26, which is of a arranged at the end of the machine, not separately shown gear is set in reciprocating motion.

The cam piece 23, which is firmly seated on the adjusting member 26, also performs the same movement. This is due to the slope the work surface 48, the Bowden cable core 46 more or less tightened. These changes in size, which change in size tion is transmitted via the Bowden cable jacket 43, the slider 40, the driver pin 41 on the guardrail 18, the as a result, a reciprocating pivoting movement about the pivot point 20 is caused. The further transmission of motion up to the thread guide 8 takes place as already described.

.To the device that is in the position shown in FIG. 4 winding. produced with tapered ends, to convert so that it now produces winding with flat ends, the adjusting member 26 is inclusive its curved pieces 23 shifted so far to the left, that the elbow 47 is free from the work surface 48 comes. In addition, when the cam piece 23 is moved to the left, the driver pin 50 is removed from the working surface 49 of the Curved piece 23 detected and including the slider 40 pushed down until the driver pin 50 on the lower end of the work surface 49 has arrived and over the same slides over. The force of the guardrail on the left lever arm 18 engaging spring 22 is over the right lever arm of the guide rail 18, the driver pin 41, the slider 40, transferred to the work surface 49 via the driver pin 50. This force, which in the winding process described above, acts as contact pressure between the slider 40 and the Bowden cable casing 43 worked and its abutment in the emigrating stop pin 59, is now completely intercepted by the curve piece 23. This means that the Bowden cable jacket 43 now no more movement of the coil arm can be transferred to the guide rail 18. Accordingly, there is now also no shortening of the stroke the traversing movement in the course of the winding process. the "Breathing" is in turn superimposed on the thread guide stroke, that the adjusting member 26 and with it the cam piece 23 in back
