EP1657329A1 - Method and device for winding a band of parallel yarns on a rotating drum - Google Patents

Abstract

A number of parallel yarns (9) are wound on a rotating drum (2), which has a cylindrical (4) and conical (3) section. An inner ring (12) carries the yarn selector mechanism (8), which consists of a number of modules, each with its own moving yarn guide, yarn cutter and yarn clamp. Each yarn is taken to its own guide and can either be active or held in reserve in the yarn clamp. The ring (12) is supported in guide grooves (13) and traversed (c) along the length of the drum. An independent claim is also included for an arrangement of winding a ribbon of separate yarns so that each yarn is taken through its own yarn guide and can be placed in a predetermined position on a winding drum. The winding arrangement can be part of a sample warping machine with appropriate traverse and selection control (10). Cross-over arrangements are carried on a concentric outer ring (14) that rotates synchronously with the drum (2) and is also traversed (c).

Description

The invention relates to a method and an apparatus for winding a band consisting of a plurality of parallel threads onto a winding body rotating about a rotation axis. Such methods and devices are used, for example, in textile technology in weaving preparation for warping the warp. But winding processes are also in other areas such. required in the wire industry. The present invention is not limited to textile applications and the term "threads" covers any elongate, windable element, regardless of the cross-sectional shape or the material.

For example, a requirement of modern warping methods is that high speeds must be used, and a change in the composition of each wound tape should be ensured. This requirement arises in particular in so-called pattern chains or short chains. However, any change in band composition, whether in the type or sequence of filaments or in the wound bandwidth, requires machine downtime, which significantly delays the work process.

It is therefore an object of the invention to provide a method and a device of the type mentioned, with which at high production speeds rapid tape changes or different tape compositions are possible. This object is achieved in procedural terms by a method having the features according to claim 1 and in device-related terms by a device having the features in claim 15.

In conventional warping machines, the threads are already brought to the warp blade on the correct thread density and bandwidth. This arrangement, apparently, complicates any modification of the tape. These disadvantages can be eliminated if the winding position of each individual thread on the winding body is determined with a yarn guide associated with this thread. The thread guides thus replace the sharpening blade, but in contrast to this they can approach arbitrary positions. The yarn guides are therefore preferably adjustable in the direction of the axis of rotation from a rest position to a working position. Thus, the yarn guide can be used alternately and so change the composition of the tape to be wound arbitrarily.

Particularly advantageously, a thread set consisting of a plurality of threads, preferably of a different type, is brought to a thread selection device arranged in the winding region of the winding body, whereby individual threads are drawn off as work threads via the thread guides and form the strip, while the remaining threads are used as stock threads on the thread selection device one clamping point are held clamped. This procedure makes it possible to perform the band change with continuously rotating bobbin, which obviously speeds up the work process considerably.

It is advantageous if, after at least one first winding sequence, the working threads of the wound strip are separated and held clamped on the thread selection device, and if in at least one second winding sequence the working threads of the strip have a different composition than during the first winding sequence. The composition of the band can also be the same at several adjacent coils. Finally, it would also be conceivable that the threads of a band not after each Winding sequence are separated, but that the tape is guided at the end of a roll directly to the beginning of an adjacent roll.

A taking place at full bobbin rotation yarn transfer can be achieved particularly advantageous if the selected work threads are first stretched by the thread guide in a driving position on the winding body in which they are stretched between the yarn guides and one nip approximately parallel to the axis of rotation and that in Run a T bobbin rotation all work threads in the driving position of one of the winding body associated inner Fadenmitnehmer sequentially detected and then separated from the nip. After disconnecting from the clamping points, the thread guides can be driven with their work threads in the tape winding position on bandwidth. This flying transfer of the clamped stock threads as work threads on the bobbin can be done at high speeds and within a single bobbin rotation.

After the construction of a tape reel turn all working threads can be sequentially detected by a co-rotating synchronously with the winding body outer Fadenmitnehmern and then clamped by the clamping point and at the same time separated from the thread guide. This is practically a flying return of the work threads in the waiting position at the terminal points.

It is obviously necessary on a cone warping machine that the thread selection device for the conical winding of the strip is displaced on a shear table in the direction of the axis of rotation or at right angles thereto. The warping drum forms the bobbin.

Evidently, it is necessary in the context of a warping process for the correct presentation of the chain on the weaving tree to introduce sub-elements in the thread bandage. The insertion of sub-elements usually requires a machine standstill in conventional methods. This disadvantage can be avoided in the inventive method in that at the beginning of a tape roll with at least a portion of the threads at least one point on the winding body with rotating winding body a compartment is formed and that in the open compartment, a sub-element is introduced. Such thread pitch may preferably serve to form a crosshair. Such a reticle later facilitates further processing, for example in the weaving mill. Similar to the flying takeover of the work threads on the winding body is thus also the shedding, especially the crosshairs and the introduction of the sub-element at full operating speed. In certain cases, it would be conceivable to use this type of shedding in conventional methods in which not every single thread is deposited over an individual thread guide. A particularly advantageous shedding arises when for striking the crosshairs at least two arranged on the winding body in relation to the circumferential direction shedding combs are moved from an outer circumference about tangential rest position in a shedding position, in which the combs projecting radially from the outer periphery and that in the course of a Winding body rotation, the threads are preferably placed alternately on the combs and between the combs. The shedding combs can be relatively easily moved with a partial rotation in their working position. Of course, this method can also be used for sizing. This is not about a cross formation, but about a separation of the threads. For the sizing division are a plurality of successively arranged Fachbildekämmen formed such that in each case only for individual threads a compartment is formed. If additionally a sizing division is provided, this is preferably done before the crosshair formation.

Evidently, the shedding and the introduction of the sub-element before starting the tape winding position, the thread guides are first moved to a read-in position for depositing the threads on the shedding combs. In this picking position, the threads are less close together than at the later tape winding position.

Preferably, a partial rod is first inserted into an open compartment, after which the compartmentalizing comb forming the compartment in question is moved back into the rest position and finally the threads divided by the partial staff are stripped off onto a partial element, preferably onto a partial cord. The sub-string is thus not actually fed into the tray, but the threads are passed to the sub-string.

Likewise, at the end of a tape roll with at least a portion of the threads at least one point on a rotating synchronously with the winding body and surrounding outer ring a crosshairs be beaten for shedding, wherein in the open compartment a sub-element is introduced and the shedding preferably with analog Means, ie with Fachbildekämmen done, as at the beginning of the tape roll.

In this way, a plurality of tape reels with the same or different thread repeat can be wound on each other or side by side on the winding body, wherein the winding body rotates continuously.

In terms of the device, it is expedient if ever a thread guide and a clamping point are assigned to a thread guide module having a gear for adjusting the thread guide and a movable clamping-cutting unit with a clamping point for clamping the thread and a cutting device for separating the thread. The cutting and clamping of the threads takes place in this way virtually the same location, whereby the flying thread change is made possible with rotating winding body.

The gear of the yarn guide module is preferably a traction mechanism with a traction means, in particular with a toothed belt on which the yarn guide is arranged such that it is movable on a yarn guide path approximately parallel to the axis of rotation of the winding body. The traction mechanism can be moved very quickly and precisely, for example with a stepper motor. Conceivable, however, would be other types of transmission, such as a push rod, at the end of the yarn guide is arranged.

The clamping-cutting unit can be mounted so movable about at right angles to the yarn guide distance, that the nip is displaceable relative to the winding body circumference between a radially outer rest position and a radially inner yarn transfer position. This lifting movement can be made for example via a pneumatic pressure cylinder.

As can be seen from Figures 1 and 2, there is a generally designated 1 warping machine essentially of a warping drum 2 as a bobbin with a cylindrical portion 3 and a conical section 4. The warping drum is rotatable about a bobbin or drum axis 6 in a frame 5 stored. A Schärtisch 7 rests on a Schärtischführung 11 and is displaceable on this parallel to the axis of rotation 6 in the direction of arrow c. On the show table 7, a thread selection device 8 is arranged, which is relative to the warping drum and at right angles to the axis of rotation and in the direction of arrow d is displaced.

The yarn selection device curves over a segment of, for example, 90 ° around the surface of the warping drum 2. A plurality of yarn guide modules 20, shown only schematically here, are arranged on the yarn selection device in the circumferential direction. From a creel, not shown here, or from another thread dispenser device, a group of threads 9 is withdrawn, with each individual thread being guided to one of the thread guide modules 20. Suitable devices, such as Yarn brakes ensure that the threads always stay taut.

For the shed for the production of crosshairs or for the sizing division at the beginning of a coil, an inner ring 12 is arranged on the cylindrical portion 3 of the warping drum 2, which carries the means for crosshairs or sizing and which rotates together with the drum. The inner ring 12 is guided in drum longitudinal grooves 13 and can be moved along the same as the shear table 7 in the direction of arrow c.

For shedding, especially for crosshairs at the end of a coil, an outer ring 14 is provided which surrounds the drum shell concentric and which is drivable in synchronism with the drum. The outer ring is mounted in an outer ring bearing 15, which in turn is supported on an outer ring slide 16 and linearly displaceable in this direction in the arrow direction c. The outer ring 14 carries the funds required for crosshairs.

In a control cabinet 10, the components are housed to control the warping machine.

FIG. 3 schematically shows the entirety of the mechanical functional groups on the warping machine with the associated drive motors, namely essentially the warping drum 2, the frame 5, the shearing table 7 and the thread selection device 8. In addition, the inner ring 12 and the outer ring 14 with the respective actuating means ,

FIG. 4a shows a perspective partial view of an inner ring 12 with a yarn selection device 8 of a warping machine. The yarn selection device 8 has a plurality of yarn guide modules, wherein the modules 20 ', 20 ", 20'" and 20 ' ^v are arranged one after the other along the ring Figure 4a further shows a shedding comb 40, the design and mode of operation of which will be detailed later A yarn guide 21 can be displaced or positioned along the drum axis in the direction of the arrow E. The movement of the yarn guide 21 can take place with a traction mechanism 33. Of course, other means for moving the yarn guide 21 are also conceivable hydraulic systems.

Hereinafter, a single yarn guide module 20 will be described in more detail with reference to Figures 4 to 6. The module has a holding plate 32, to which a gear unit 33 and a clamping cutting unit 22 are attached. The gear unit has a traction mechanism with a toothed belt 29. The toothed belt can be driven via a yarn guide drive 34, which is preferably a stepper motor. At one of the two parallel Zahnriementrums a yarn guide 21 is attached, which can travel in the direction of arrow e a thread guide section FS. In the rest position RS is the thread guide 21 set back behind the clamping cutting unit. The clamping cutting unit 22 is arranged on a lifting carriage 26 which is mounted displaceably in a guide 35. The drive means is a pneumatic pressure medium cylinder 28.

The clamping-cutting unit has a Doppelhebearm 25 which is articulated on the lifting carriage 26 and the upper lever arm via a pneumatic pressure medium cylinder 27 can be activated. The actual cutting device 24 is formed on the lower lever arm by a cutting edge. Immediately behind the cutting plane is a nip 23, which is also activated via the Doppelhebearm 25.

The supplied working thread or supply thread 18/19 is introduced via a thread guide tube 36 which opens on the side of the double lever arm in such a way over the nip 23, that the thread is on the thread guide section of the thread guide 21. The thread guide has a notch or groove which prevents the thread from sliding away.

For a better understanding of the following functional description of the yarn guide module 20, the inner thread driver 30 assigned to the drum is also shown in FIG. 4b. This is not shown here by means means able to detect a clamped in the correct position clamping thread and entrain.

As long as a thread is clamped in the starting position shown in Figure 5 on a yarn guide module, it serves as a stock thread 19, which can be included at any time as working thread in the warping process to form a tape. For this purpose, the yarn guide 21 is activated according to FIGS. 7a and 7b, so that he covers a part of the thread guide stretch FS and first assumes a thread take-up position FM. The lifting carriage 26 is already in the lowered position shown in FIG. The required for the achievement of thread take-up position FM thread supply is withdrawn via the yarn guide tube 36. The rotational movement of the drum is tuned to the movement of the yarn guide 21, that immediately after reaching the thread take-up position FM, the lower Fadenmitnehmer 33 entrains this and every other work thread of the current roll.

Immediately after the secure detection of the thread, the nip 23 is released, so that the working thread with the peripheral speed of the inner Fadenmitnehmers 30 is withdrawn. This situation is shown in FIGS. 8a and 8b. Until then, all active thread guide modules on the thread selection device are working simultaneously.

Following this, according to FIGS. 9a and 9b, the yarn guide 21 is moved a little further along the yarn guide section FS in order to be read into a shedding comb 40 for hitting a crosshair. This shedding process will be described in more detail below. The shedding comb for a crosshair has U-shaped forked comb ends 42, in each of which a single working thread can be deposited. Between the individual comb ends 42 threads can also be stored. As is shown symbolically in FIG. 9a, each yarn guide 21a, 21b, 21c, etc. is then moved in sequence by thread guide modules following in the circumferential direction to such an extent that a work thread is alternately placed on a comb end and between a comb end. After hitting the crosshairs and after inserting a partial element drive in the manner described below all active yarn guides 21, 21a, 21b, 21c, etc. their respective work threads on the actual winding position of the belt 17, the width of which is clearly much smaller than the yarn tape width when reading on the shedding comb 40. The yarn guide 21 keep their relative position to each other now until the end of the roll is reached, moving the entire yarn selector on the sharpening slide.

Once the end of a tape roll is reached and as soon as there are formed with similar agents crosshairs, again drive all active yarn guide 21 on an outer thread driving position FM, in which all working threads 18 are passed to an outer thread driver 31 and be entrained by this. This outer thread driver is associated with an outer, the drum concentric surrounding and co-rotating with the drum outer ring 14, which is shown only symbolically in Figure 10a / 10b. This "gathering" of the threads is done in preparation for the cutting operation shown in Figures 11a / 11b.

The lifting carriage 26 is driven at each yarn guide module 20 in the upper end position, so that the nip 23 can detect the withdrawn thread. Practically at the same time, the cutting device 24 is activated, on the one hand frees the just-worked working thread 18 from the thread guide 21 and at the same time held back as Vorratsfaden 19 at the nip in the ready position.

As can be seen from FIG. 12, the means for hitting a crosshair at the beginning of a coil are arranged on the inner ring 12. The situation illustrated in FIG. 12 corresponds approximately to that according to FIG. 9, with adjacent threads alternately arranged in successive shedding combs possible stripping of the split thread assembly from the sub-rod 43 on the withdrawn part cord 49th

The purpose of a thread scraper 48, which is shown in Figure 15a and which is displaceable in the direction against the Teilschnurhülse 44 towards. FIGS. 15a / 15b show a shedding comb 40 in the standby position, that is to say with combs 42 projecting radially outward. The shifter 43 is still pulled back, so that according to FIG. 16a / 16b the shedding comb can be wound over. In each case, the upper threads 53 are in the U-shaped ridge ends 42 and the lower threads 52 lie between the combs directly on the comb shaft 41. The distance between the lower and the upper threads forms the open compartment 51. Depending on the bandwidth of the later Schärbandes the entire shedding comb or only a portion of it is wrapped.

As soon as all active working threads have been read into the shedding comb, the partial rod 43 is extended according to FIG. 17a / 17b and then the shedding comb 40 is turned back into its radially inner rest position.

This situation is shown in Figure 18a / 18b. The upper threads 53 now rest directly on the partial rod 43 and the lower threads 52 still rest on the comb shaft 41. The partial rod 43 has grasped the partial cord sleeve 44 at the end and the latter is freed from the sleeve holder 45. Now, according to FIG. 19a / 19b, the thread scraper 48 can be advanced, which strips the lower and upper threads 52/53 beyond the sub-line sleeve 44 onto the sub-line 49. Subsequently, the thread scraper 48 moves back and the shedding comb 40 remains in this waiting position according to Figure 20a / 20b until it is turned out to a new shed formation.

The shedding at the end of a reel is done with similar means as at the beginning of the reel, i. also with shedding combs. As already mentioned in the introduction, these shedding combs are assigned to the outer ring 14 whose diameter is dimensioned such that it is larger than the largest possible winding diameter. Unlike the beginning of the winding, however, not a partial cord but a flexible partial ligament is introduced into the open thread compartment as a partial element, wherein the design of the compartmentalised part as well as the method steps are not the same as on the inside. According to FIG. 21a / 21b, a curved shedding comb 40 with comb ends 42 is likewise arranged on a comb shank 41. The flexible sub-band 54 with its angled end is disposed below the comb shaft 41 and can be advanced from the drum inside. An upper partial rod 56 can also be extended parallel to the comb shaft 41. In addition, a stripper sleeve 57 is provided which surrounds the entire rod 56. In the illustrated starting position, in turn, lower threads 52 and upper threads 53 are read into the shedding comb 40, i. the thread guides 21 associated with each thread (FIG. 9a) ensure that the threads assume the correct overwinding position.

According to FIG. 22a / 22b, the reading-in process is completed and the partial rod 56 is moved into the open compartment 51. Subsequently, according to FIG. 23a / 23b, the comb shaft 41 is turned off so that the upper threads 53 lie on the partial rod 56 and the lower threads 52 on the comb shaft 41.

In a next step according to FIG. 24 a / 24 b, the stripper sleeve 57 is extended, with the lower threads 52 falling onto the partial band 54. On the other hand, the upper threads 53 initially lie on the end of the partial rod 56. The end of the partial rod Aligns with the angled end of the sub-band 54.

As soon as the stripper sleeve 57 travels the last distance, the upper threads 53 fall onto the finished roll, but outside the sub-strip 54 (FIG. 25a / 25b). Thus, the sub-element is introduced and can be advanced to form a pitch on the next following winding by a winding width. The shedding comb 40 is again rotated into the active position for shedding and the shank 56 and the shroud 57 are retracted to the starting position (Figure 26a / 26b). Of course, the method described with reference to Figures 21a / 21b to 26a / 26b can also be applied to the winding start or on the inner ring.

A complete winding process will be described below with reference to the schematic representation according to FIG 27. The diagram shows from bottom to top ascending the individual winding sequences with a view at right angles to the drum. In the upper third of the image, the viewing direction is tangential to the warping drum 2 with the cylindrical section 3 and the conical section 4, and with an already completed winding 37. The bottom two-thirds of the representation show a practical development of the drum shell in the various operating sequences, with the right Angular position of the drum is specified.

A winding process begins with the presentation phase 60, in which the yarn selection device 8, as described above, transfers the work threads 18 to the drum with the aid of the active yarn guides 21A and brings them into the correct relative position. The diagram shows a total of 6 active yarn guides 21A. With two passive thread guides 21P, the corresponding thread guide modules remain in its neutral ready position, in which the supply threads 19 rest.

In the lower overwinding phase 61, the working threads 18 are read into the lower shedding combs 40 with the aid of the active thread guides 21A. As described above, the split threads are pushed onto the sub-string and then the active thread guides 21A move the threads together on the one hand Bandwidth B of the warp 17 and on the other hand simultaneously to the left at the foot point 38 of the conical section 4. At the end of this process, the drum has a Rotation of 360 ° covered.

Now follows the actual winding phase 62 to build the roll 37, which depending on the thread quality as many drum revolutions Nx360 ° are required until the desired winding height H is reached.

After the winding 37 is completed, the upper overwinding phase 63 follows for reading in the threads in the upper shedding combs 40 on the outer ring 14. For this purpose, the active yarn guides 21A travel further to the left and at the same time again apart to the scanning width. For the shedding and for advancing the sub-band in the open compartments, the drum again requires a full revolution of 360 °.

Subsequently, the yarn guides 21A ride together in a row to transfer the working threads 18 together to the outer Fadenmitnehmer 31, wherein the yarn guide modules cut the work threads and in turn detect by clamping. This action is shown as upper presentation phase 64.

Without stopping the drum can now be wound in the same manner, the next winding, possibly at the Fadenwähleinrichtung 8 other threads are retrieved. Evidently, the inner ring 12, the outer ring 14 and also the thread selection device 8 move to the right by a bandwidth B.

Shown in FIGS. 28a and 28b are shedding combs for the sizing division. With the aid of a first shedding comb 40 '(FIG. 28a), a first thread is deposited in each case into a comb end 42' arranged at the beginning of the comb. Further comb ends are arranged at predetermined, periodic distances from each other, whereby each individual threads form a compartment. Through this subject, a sub-element, such as a partial rod is feasible. A next, second shedding comb 40 "following the first shedding comb (FIG. 28b) has comb ends 42" for a second thread or second threads, wherein the comb ends of the first shedding comb are offset by one thread point with respect to the first shedding comb. Similarly, the next shedding combs are formed, i. In the case of the third shedding comb, the respective comb ends would have been displaced by a further point, etc. In the example according to FIG. 28a / b, seven shedding combs would therefore be necessary for the shimming division.
