Wing maneuvering

2 shows a wing traversing unit 14 or 14.1 in cross section, which Is part of the traversing device 7. It points, depending on the number at the same time threads to be wound on a spool 2 or 2.1, the Traversing device 7 a corresponding number of traversing units 14 or 14.1 arranged next to each other, as shown with FIGS. 4a.1 to 4b.2 is.

In the traversing unit 14; 14.1 of FIG. 2 are so-called traversing wings shown which, as can be seen from FIGS. 4 to 4b.2 or 5 to 5b.1, according to the transport of the thread in one direction or the other have different positions.

Furthermore, it can be seen from Fig. 2 that it is essentially each other Opposing wing pairs are, as is also the case with FIGS. 4 and 5 is shown, the individual wings are driven separately, as is the case with the Figures 4a.1 to 4b.1 and 5a.1 and 5b.1 is shown.

The wings shown with solid lines correspond to Wings of the figures 4 to 4b.2 described below and those with solid and dash-dotted lines combine the wing shown Wings of the wings of Figures 5 to 5b.1 described later.

From Fig. 2 it can further be seen that the thread F corresponds to the Direction of a thread running from top to bottom, with a view of the figure seen, has.

With the help of the term "from top to bottom" later the individual wings referred to as "upper" or "lower" wings.

Further details of this figure are in connection with the description of the other figures mentioned.

Now consider Fig. 4, which an arrangement of traversing wings in Represents direction of view I (Fig. 2) in the CAD drawing style, so there is an upper one left (looking at the figure) outer wing with 15 and a lower left Outer wings marked with 16, while upper intermediate wings with 17 and 18 and lower intermediate wings are marked with 19 and 20. Next is one upper right outer wing with 21 and a lower right outer wing with 22 featured.

The specified number of wing pairs per stroke length H.1 and the length of the Wing, seen from its axis of rotation to the tip, is chosen so that for example lines of symmetry S, which by adjacent intersection of Circles of movement of the tips of the wings 15, 17, 18, 21 or 16, 19, 20, 22, For example, the circles of movement designated with K.1, K.2 and K.3 pulled through the axes of rotation of the wings 17 or 19 and 18 or 20, Include angle µ of essentially 45 degrees.

Furthermore, it can be seen from FIG. 4 that the upper outer wings 15 and 21 (Fig.4a) compared to the lower outer wings 16 and 22 (Fig. 4b) in this way are offset that the tips of the upper outer wings 15 and 21 continue to counter the thread F protrudes as the tips of the lower outer wings 16 and 22 thereby being able to take over the thread.

It follows that, as from the circular movements shown in FIG Wing can be seen, the thread transfer from the lower outer wing 16 or. 22, on the upper outer wing 15 resp. 21, takes place.

The displacement of the upper outer wings 15 and 21 compared to the lower Outer wings 16 and 22 is also from the axes of rotation shown offset the outer wing is recognizable, with the axis of rotation of the upper left Outer wing 15 with 23 and the axis of rotation of the lower left outer wing 16 with 24, while the axis of rotation of the upper right outer wing 21 with 27 and the axis of rotation of the lower right outer wing 22 is identified by 28.

From Fig. 4 it can also be seen that the circular movements of the Intermediate wings 17, 19 and 18, 20 are concentric, which means that the Rotation axes 25 and 25.1 for the intermediate wings 17 and 19 and the rotation axis 26 and 26.1 are provided for the intermediate wings 18 and 20 in line.

Furthermore, the thread transfer to the outer wings is more precise shape, ramps 29 and 31 provided, the ramp 29 for the left Outer wing 15; 16 and the ramp 31 for the right outer wing 21; 22 is provided.

4b.1, the ramps 29 and the thread guide ruler 47 are also shown shown according to Figures 4 and 4b.

Furthermore, the ramp 29 can be a stroke limiter 30 and the ramp 31 have a stroke limiter 32. These stroke limiters are used for precise Position of the thread at the end of the traverse stroke, occasionally also simply a stroke called.

In Fig. 4a.1 there is also a thread ruler 47 with dash-dotted lines shown, this thread ruler 47 any predetermined contour can have and does not have to be rectilinear, but preferably rectilinear is.

Wing drive

As FIGS. 4a.1 to 4b.2 show, all of the upper wings and all of the lower wings are Wing of a traversing unit 14.a or 14.b each together by means of a Belt drive 33 or 33.1 driven.

As a variant, 33 or 33.1 gears in place of a belt drive an arrangement performing the same drive function, not shown here be provided.

Figures 4a.1 and 4a.2 show the wings of the top row and the figures 4b.1 and 4b.2 the wings of the lower row. Accordingly, they are 4 to 4b also in FIGS. 4a.1 or 4a.2 and 4b1 or 4b.2 listed.

4a.1 and 4a.2 show three wing traversing units 14.a, one each Coil, arranged on a total base plate 49, here for example 3 Wing traversing units, but the number is not limited to these three is limited, but depending on the number of coils there is one unit per coil 14a provided.

As can be seen from FIG. 2, this is the base plate for the upper wings 15, 17, 18 and 21.

4a.1, as mentioned earlier, is drawn in the style of a CAD drawing, that is, elements that are provided behind the front elements not with dashed lines, but also with solid lines shown. The way in which the elements are stacked is shown in Fig. 4a.2 shown. This figure shows the base plate 49 in viewing direction II (Fig.4a.1) and below, with a view of the figure, with dash-dotted lines Lines shown, the traversing units 14.a and the axes of rotation 23, 25, 26th and 27 of the vanes 15, 17, 18 and 21, which rotate about these axes of rotation (in this figure not shown) are rotatably mounted in the base plate 49.

Above the base plate 49 there is one wing wing unit 14.a. Belt drive 33 is provided, which the wings 15, 17, 18 and 21 on the Drives axes of rotation 23, 25, 26 and 27. As an overdrive element is a Toothed belt 58 (teeth are not shown) is provided.

The toothed belt 58 runs per traversing unit 14.a, as shown in FIG. 4a.1, via an overdrive roller 53 and drive rollers 56, each of which Roll per wing is provided, and via a guide roller 54 to the to give individual wings the corresponding direction of rotation.

From the figure it can be seen that the belt drive the wings in the per wing drives shown directions of rotation.

The axis of rotation 51 of the overdrive roller 53 is, as can be seen from FIG. 4a.2, shown longer than the axes of rotation 23, 25, 26 and 27, because the overdrive roller 53 is also correspondingly longer by a belt overdrive 34 which, as shown in Fig. 4a.1, in two wing traversing units 14.a is guided over a tension roller 52. As can also be seen from FIG. 4a.2, the third axis of rotation 51 (seen from left to right on the figure) longer than that two preceding axes of rotation 51, namely in addition to Belt overdrive 34 still include a main belt drive 36, which further by a displaceable tensioning roller 48, a deflection roller 55 and around a motor pinion 35 is guided around. A torque that from a in Drive housing 13 (Fig. 1) stationary drive motor 59 on the Motor pinion 35 is released, is via the main belt drive 36 on the Belt transfer 34 and transmitted from this to the belt drives 33.

The upper overdrive roller 53 or 53.1 is also connected by means of a shaft 66 the lower overdrive roller 53.a (seen with a view of FIG. 2 or 3) connected so that the torque of the overdrive rollers 53 and 53.1 on the Overdrive rollers 53.a and thus on the belt drive 33.1 or 33.3 can be transferred.

Furthermore, the wings 16, 19, 20 and 22 each have a drive roller 56 provided which a toothed belt 58.1 in the appropriate manner pick up the timing belt to the wings shown with the arrow Direction of rotation transmitted. The toothed belt 58.1 is further on Deflection pulley 54 and around the overdrive pulley 53a.

As mentioned earlier, the traversing device 7 can be pushed in means that the motor pinion 35 only engages in the main belt drive 36, when the chanching device 7 is inserted in its operating position.

If the traversing device 7 is not pushed in, the belt guide runs such that, as shown with dashed lines, the tension roller 48 in the position shown by dashed lines is not to thereby inserted traversing device 7 the belt of the main belt drive 36 to keep excited.

The axis of rotation of the deflection roller 55 is identified by 60. The axes of rotation the deflection rollers 54 and tension roller 48 are not shown. 2 is For the sake of simplicity, only the belt drive 33 or 33.1 or 33.2 or 33.3 shown.

Swiveling of the base plates

Figures 4b.1 and 4b.2 show the arrangement according to the invention lower wing, in which one wing wing unit 14.b one each Axis of rotation 51 pivotable unit base plate 50 is provided, what with arrows 62 and 62.a and 62.b is shown.

The predetermined distance between the entire base plate 49 and individual unit base plates 50 is replaced by a spacer sleeve 61 ensured. This spacer sleeve 61 has a smaller diameter Bearing extension 64 on which the base plate 50 pivots to thereby, as shown in Fig. 3 and 4b.1, the base plates corresponding to the Swivel arrows 62 or 62.a or 62.b to pivot about the axis of rotation 51. The base plate 50 lies entirely on that in FIG. 3 and in FIG. 4b.2 spacer sleeve 61 shown cut off.

In order to ensure the pivoting of the base plate 50, each base plate 50 provided with one or two bevels 65, which at least one Correspond to a circular section with the swivel radius R, with the radius R extends from the axis of rotation 51 and half the width b of the base plate 50 corresponds. These bevels 65 of the individual base plates 50 hit accordingly at a connecting line 63 which the Axes of rotation 51 connects. Now, the base plates 50 from the one with FIG. 2 operating position shown are pivoted into the rest position shown in FIG. 3, For example, to replace or clean the wings, the primary a fixing screw 57 (Fig.3) loosened, which against a bearing extension 64 of Spacer 61 presses and then first the outermost base plate on the left in Counterclockwise, pivoted by approx. 90 ° according to arrow 62 then the base plates arranged to the right of it in accordance with the Arrows 62.a by 180 degrees and then the Base plate 50 arranged on the extreme left according to arrow 62 swivel another approx. 90 ° so that the end position of this base plate is the End position of the other base plates corresponds.

As the last step, the outermost base plate is turned clockwise on the right Arrow 62.b pivoted through 180 °.

In this pivoted position of the base plates 50 shown in FIG. 3 the wings with ease without disassembling the entire traversing device 7 be replaced or cleaned.

4b.1 has a CAD system similar to that of FIG. 4a.1 Representation, that is, as already mentioned, for those elements, which are in Fig. 4b.1 behind the base plate 50, not dashed Lines, but solid lines were used. However, in order to Location of wings 16, 19, 20 and 22 and the drive of these wings clarity provide, is the effective position of the drive 33.1 and the wing in Fig. 4b.2 16, 19, 20 and 22 compared to the base plates 50.

5 to 5b.1 show that with a shortened stroke H.2 compared to a longer stroke H.1 of FIG. 4, instead of four pairs of wings, which rotate opposite each other, uses two pairs of wings can be compared, which, however, are specified as double wings the single wings of FIGS. 4 to 4b.2.

5 shows the mutual position of the upper and lower analog to FIG. 4 Wing, seen with a view of FIGS. 2 and 3.

An upper left wing, seen with a view of FIG. 5, is made up of the Wing halves 37 and 38 together, the right upper wing from the Wing halves 41 and 42, while the lower wing on the left emerges from the halves 39 and 40 and the lower wing on the right composed of halves 43 and 44.

Compared to the staggered arrangement of the upper wings shown in FIG. 2 To get the lower wing, the upper wing is 37/38 about the axis of rotation 67, the lower wing 39/40 around the axis of rotation 68 and the upper wing 41/42 around the axis of rotation 70 and the lower wing 43/44 about the axis of rotation 69, rotatable.

The directions of rotation of the respective wings are one Direction of rotation arrow shown.

As explained with reference to FIG. 4, the position of the wing halves shown in FIG. 5a is this double wing, as shown, also chosen so that the earlier mentioned angle µ under the conditions mentioned essentially is guaranteed. A corresponding explanation is therefore unnecessary in this regard for FIGS. 5 to 5b.1.

What is shown for FIG. 5a in this regard also applies to FIG. 5b. Like that for The statement made in FIG. 4 applies to FIGS. 4a and 4b, which is why only in FIGS. 4 and 4a the angle µ is shown.

5 shows, as already mentioned, the upper and lower wing pairs, while Fig. 5a only the upper wings 37/38 and 41/42 and Fig 5b only represents the lower wings 39/40 and 43/44.

In Fig. 5 the whole is made up of the upper and lower wings Composing traversing unit with 14.1, while in Fig. 5a the upper Wing of the traversing unit with 14.1a and the lower wing in Fig. 5b Traversing unit are marked with 14.1b.

5a and 5b are the thread ruler 47 and in FIG. 5b ramps 29 and 31 are also shown.

Figures 5a.1 and 5b.1 represent in an analogous manner to Figs. 4a.1 and 4b.1 a total base plate 49.1 (Fig.5a.1) and a unit base plate 50.1 (Fig.5b.1), which is to show that the pivoting of the base plates 50.1 in the same way as for the base plates 50 and that also happens Connection and the drives work in the same way as for Fig. 4a.1 to 4b.2, which is why these details are not repeated for FIGS. 5a.1 and 5b.1 will. Correspondingly, elements with analog functions are also compatible with the provided analog reference numerals.

In this respect, FIGS. 6 to 8 show a variant compared to FIGS. 2, 3 and 4a.1 to 4b.2, as the drive of the overdrive roller 53 or 53.1 and 53a not by means of the belt overdrive 34, but by means of a drive shaft 76 is carried out, which their torque via a drive pinion 75 to the in Fig. 6 and 7 shown overdrive gears 73 and 74 transmits which in turn drive the overdrive rollers 53 via a connecting shaft 81.

The shaft 76 has a coupling half 78, which in connection with a Coupling half 79 of a drive motor 80 non-positively connected can be brought when the traversing device in the operating position is inserted.

The drive motor 80 is stationary in the same way as the drive motor 59 Drive housing 13 provided.

The overdrive gears 73 and 74 and the drive pinion 75 have one matching helical or spiral teeth.

Furthermore, the base plate 49 has hinge and bearing extensions 71, in which the shaft 76 is rotatably supported and as a left axial stop with As seen in Figure 8, serves for the position of the drive pinion 75.

In contrast to the base plates 50, the lower base plate 50.2 is the Figures 4a.1 to 4b.2 and Figures 5a.1 and 5b.1 in an analogous manner Base plate 49 for all traversing units continuously and in turn points Hinge and bearing extensions 72 in which the shaft 76 is also stored and which on the other hand the right stop, with a view seen on Figure 8, form for the position of the drive pinion 75.

For transmitting the torque from the shaft 76 to the drive pinion 75 slot nuts 77 are provided in each case.

For assembly and disassembly of hinge and bearing extensions 71 and 72 together Shaft 76 and drive pinion 75 are the hinge and bearing extensions 71 and 72 each fastened to the base plate 49 or 50.2 with connecting screws 82.

So that the base plate 50.2 is pivoted into the open position shown in FIG. 7 are the screw heads 83 of the connecting screws 82 provided sunk.

With the possibility of the base plate 50.2 in the manner shown in FIG. 7 swinging open, there is also the possibility of the wings in more comfortable Location to clean or replace.

The elements that are not marked with numbers correspond to the elements of the preceding figures and are therefore not mentioned again or featured.

Furthermore, there is a spacer 84 on the base plate 49 and a spacer 85 attached to the base plate 50.2, which lie against each other when the Base plates 49 and 50.2 are in the position according to FIG. 6. So that's the Distance between the wings of the two base plates guaranteed.

Supports 86 serve as legs on which the traversing device 7 on the Rails 9 in the operating position on a handle belonging to a front plate 88 8 can be inserted.

Ultimately, the traversing units 14 to 14.1b are in a housing 87 housed.

A traversing device as claimed in claim 1, characterized in that in a wings traversing unit at least two wings pairs with substantially oppositely arranged wings are provided per stroke (H.1; H.2), with the rotational axes of the pair of wings effecting the reversal of the stroke of the yarn being arranged mutually offset in such a way that the receiving wings projects further towards the yarn and further in the direction of the stroke than the wings delivering the yarn.
10. A traversing device as claimed in claim 1, characterized in that upper outer wings (15, 21; 37, 42) are offset towards the lower outer wings (16, 22; 39, 44), as seen in the running direction of the yarn, in such a way that the tips of the upper outer wings (15, 21; 37, 42) guiding the yarn (F) into the stroke (H.1; H.2) project further towards the yarn (F) than the tips of the lower outer wings (16, 22; 39, 44) guiding the yarn (F) towards the edge of the stroke (H.1, H.2).
11. A traversing device as claimed in claim 1, characterized in that the yarn transfer at the edge of the stroke (H.1, H.2) occurs from a lower outer wings (16, 22; 39, 44) to an upper outer wings (15, 21; 37, 42), as seen in the running direction of the wings (F).
12. A traversing device as claimed in claim 1, characterized in that the wings of a wings traversing unit can be driven by a toothed belt drive (33 to 36) or a toothed wheel transmission (73 to 76).
13. A traversing device as claimed in claim 12, characterized in that the transmission and the motor (59, 80) driving the transmission are arranged towards one another in such a way that the motor is coupled on only after the complete insertion of the traversing unit on the transmission.
14. A traversing device as claimed in claim 13, characterized in that the motor (59, 80) is arranged stationarily.
15. A traversing device as claimed in claim 9, characterized in that at the two end zones of the stroke a ramp (29, 31) with a stop (30, 32) is additionally provided in order to render the transfer of the yarn more precise.
16. A traversing device as claimed in at least one of the preceding claims in a winding machine for winding up at least one textile yarn (F), in particular a yarn made from synthetic endless filaments, with a supporting element (9) for an exchangeable traversing module, characterized in that the traversing device on the supporting element is insertable into the winding machine.
