Method And Device For Winding A Strip Consisting Of A Plurality Of Parallel Threads Onto A Drum Rotating About An Axis Of Rotation

Abstract

The invention relates to a method for winding a strip (17) consisting of a plurality of parallel threads (18) onto a rotating warping drum (2), wherein the winding position of each individual thread is determined with the aid of a thread guide (21) which is associated with a thread selection device (8) and which is allocated to said thread. The thread guides (21) are displaced in the direction of the axis of rotation (6) of the warping drum (2) from a rest position into a working position and the individual threads (18) are seized successively by an internal thread carrier (30) associated with the warping drum (2).

Description

The invention relates to a method and a device for winding a strip consisting of a plurality of parallel threads onto a winding body rotating about an axis of rotation. Methods and devices of this type are used, for example, in the textile industry in weaving preparation for warping the warp. However, winding processes are also required in other sectors, such as, for example, in the wire industry. The present invention, then, is not restricted to just textile applications, and the expression “threads” covers any elongate windable element, irrespective of cross-sectional shape or of material.

One requirement in modern warping methods is, for example, that the work must be carried out at high speeds, while a change in the composition of each wound strip should be ensured. This requirement arises particularly in what are known as pattern warps or short warps. However, any changeover of the strip composition, whether in generic type or the sequence of the threads or in the wound strip width, requires a machine standstill, thus considerably delaying the work process.

An object of the invention, therefore, is to provide a method and device of the type initially mentioned, by means of which rapid strip changes or different strip compositions are possible at a high production speed. This object is achieved, in terms of method, by means of a method having the features according to claim 1 and, in terms of device, by means of a device having the features in claim 15.

In conventional warping machines, the threads are brought to the correct thread density and strip width even on the reed. This arrangement clearly makes any modification of the strip difficult. These disadvantages can be eliminated if the winding position of each individual thread on the winding body is defined by means of a thread guide assigned to this thread. The thread guides therefore replace the reed, although, in contrast to the latter, they can come into any desired positions. The thread guides can therefore preferably be adjusted in the direction of the axis of rotation out of a position of rest into a working position. The thread guides can consequently be used alternately and thus change, as desired, the composition of the strip to be wound.

Particularly advantageously, a thread group consisting of a plurality of threads, preferably of different generic type, is led up to a thread selection device arranged in the winding region of the winding body, individual threads of these being drawn off as working threads via the thread guides and forming the strip, while the remaining threads are held clampingly as stock threads on the thread selection device in each case by means of a clamping point. This procedure makes it possible to carry out the strip change while the winding body is rotating continuously, thus obviously speeding up the work process considerably.

Under these circumstances, it is advantageous if, after at least one first winding sequence, the working threads of the wound strip are separated and are held clampingly on the thread selection device, and if, in at least one second winding sequence, the working threads of the strip have a composition other than that during the first winding sequence. However, the composition of the strip may also be identical on a plurality of adjacent laps. Finally, it would also be conceivable that the threads of a strip are not separated after each winding sequence, but, instead, the strip is guided directly, at the end of one lap, to the start of an adjacent lap.

A thread transfer taking place during a full rotation of the winding body can be achieved particularly advantageously when the selected working threads are first tensioned by means of the thread guides into a take-up position above the winding body, in which position they are freely tensioned, approximately parallel to the axis of rotation, between the thread guides and a clamping point in each case, and in that, in the course of a rotation of the winding body, all the working threads in the take-up position are picked up successively by an inner thread driver assigned to the winding body and are thereafter separated from the clamping point. After separation from the clamping points, the thread guides, together with their working threads, can be moved into the strip winding position to the strip width. This flying transfer of the clamped stock threads as working threads onto the winding body can take place at high speeds and within a single rotation of the winding body.

After the build-up of a strip lap, once again, all the working threads can be picked up successively by an outer thread driver corotating synchronously with the winding body and can thereafter be clamped once again by the clamping point and at the same time separated from the thread guide. In practice, therefore, a flying return of the working threads into the standby position at the clamping points takes place again.

On a cone warping machine, it is clearly necessary, for the conical winding of the strip on a warping table, that the thread selection device is displaced in the direction of the axis of rotation or at right angles to this. The warping drum in this case forms the winding body.

Clearly, within the framework of a warping process, for the correct feed of the warp onto the beam, it is necessary to introduce dividing elements into the composite thread structure. In conventional methods, as a rule, the insertion of dividing elements always requires a machine standstill. In the method according to the invention, this disadvantage can be avoided in that, at the start of a strip lap, a shed is formed with at least some of the threads at least one location on the winding body, while the winding body is rotating, and in that a dividing element is introduced into the open shed. Alternatively, however, the shed may also be formed by means of shedding combs which are arranged on an inner ring corotating synchronously with the winding body and surrounding the latter. Such thread division may preferably serve for forming a lease. Such a lease makes further processing, for example in the weaving mill, easier at a later stage. Thus, shedding, in particular leasing, and the introduction of the dividing element at full working speed also take place in a similar way to the flying take-over of the working threads onto the winding body. In specific instances, it would be conceivable to employ this type of shedding even in conventional methods in which not every individual thread is deposited via an individual thread guide.

Particularly advantageous shedding arises when, to beat up the lease, at least two shedding combs arranged on the winding body one behind the other with respect to the circumferential direction are moved out of a position of rest approximately tangential to the outer circumference into a shedding position in which the comb ends project radially away from the outer circumference, and, in the course of a rotation of the winding body, the threads are preferably deposited alternately onto comb ends and between the comb ends. The shedding combs can in this case be moved relatively simply with a part rotation into their working position. This method, however, may, of course, also be used for sizing division. Leasing is not involved here, but, instead, the threads are to be kept apart from one another. For sizing division, a plurality of shedding combs arranged on behind the other are arranged in such a way that a shed is formed in each case for only individual threads. If sizing division is additionally provided, this preferably takes place before leasing.

Clearly, shedding and the introduction of the dividing element take place before the strip winding position is assumed, the thread guides first being moved to a reading in position for depositing the threads onto the shedding combs. In this reading in position, the threads lie less closely to one another than in the later strip winding position.

Preferably, a crossing rod is first introduced into an open shed, the shedding comb which forms the respective shed thereafter being moved into the position of rest again, and, lastly, the threads divided by the crossing rod being stripped off onto a dividing element, preferably onto a dividing cord or a dividing band. The dividing cord or the dividing band is therefore not actually drawn into the shed, but, instead, the threads are transferred to the dividing cord or the dividing band.

Likewise, at the end of a strip lap, a lease for shedding can be beaten up with at least some of the threads at least one location on an outer ring rotating synchronously with the winding body and surrounding the latter, a dividing element being introduced into the open shed, and shedding preferably taking place by similar means, that is to say by means of shedding combs, to those at the start of the strip lap.

A plurality of strip laps having an identical or a different thread repeat can thus be wound onto the winding body one against the other or next to one another, the winding body rotating uninterruptedly.

In terms of the device, it is expedient if in each case a thread guide and clamping point are assigned to a thread guide module which has a mechanism for adjusting the thread guide and a movable clamping/cutting unit with a clamping point for clamping the thread and with a cutting device for separating the thread. The cutting and clamping of the threads thereby take place virtually at the same location, thus making it possible to have the flying thread change while the winding body is rotating.

The mechanism of the thread guide module is preferably a traction mechanism with a traction means, in particular with a toothed belt on which the thread guide is arranged in such a way that it can be moved over a thread guide distance approximately parallel to the axis of rotation of the winding body. The traction mechanism can be moved very quickly and accurately, for example, by means of a stepping motor. Other types of mechanism would also be conceivable, however, for example a push rod, on the end of which the thread guide is arranged.

The clamping/cutting unit can be mounted movably, approximately at right angles to the thread guide distance, in such a way that the clamping point is displaceable with respect to the winding body circumference between a radially outer position of rest and a radially inner thread transfer position. This stroke movement may be performed, for example, via a pneumatic pressure medium cylinder.

As is evident from FIGS. 1 and 2, a warping machine, designated as a whole by 1, consists essentially of a warping drum 2 as a winding body with a cylindrical portion 3 and with a conical portion 4. The warping drum is mounted in a stand 5 rotatably about a winding body axis or drum axis 6. A warping table 7 rests on a warping table guide 11 and is displaceable on the latter parallel to the axis of rotation 6 in the direction of the arrow c. Arranged on the warping table 7 is a thread selection device 8 which is displaceable in relation to the warping drum and at right angles to the axis of rotation of the latter, this time in the direction of the arrow d.

The thread selection device curves around the surface of the warping drum 2 over a segment of, for example, 90°. A multiplicity of thread guide modules 20, illustrated merely diagrammatically here, are arranged closely in succession in the circumferential direction on the thread selection device. A thread group 9 is drawn off from a bobbin creel or from another thread dispenser device, not illustrated in more detail here, each individual thread being guided to one of the thread guide modules 20. Suitable devices, such as, for example, thread brakes, ensure that the threads remain constantly tensioned.

For shedding in order to produce leases or for sizing division at the start of a lap, an inner ring 12 is arranged on the cylindrical portion 3 of the warping drum 2, carries the means for leasing or for sizing division and rotates together with the drum. The inner ring 12 is guided in drum longitudinal grooves 13 and can be displaced along these, in the same way as the warping table 7, in the direction of the arrow c.

For shedding, in particular for leasing at the end of a lap, an outer ring 14 is provided which surrounds the drum casing concentrically and which can be driven synchronously 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 is displaceable linearly on the latter in the direction of the arrow c. The outer ring 14, too, carries the means required for leasing.

The components for controlling the warping machine are accommodated in a control cabinet 10.

FIG. 3 shows diagrammatically the whole of the mechanical function groups on the warping machine together with the drive motors belonging to these, to be precise, essentially, the warping drum 2, the stand 5, the warping table 7 and the thread selection device 8. Included in these are the inner ring 12 and the outer ring 14 with the respective actuation means. Clearly, here, both the inner ring 12 and the outer ring 14 are elements which are released from the warping drum 2, but which can be driven in rotation synchronously with the warping drum 2.

FIG. 4 a shows a perspective part view of a thread selection device with thread guide modules of a warping machine. The thread selection device 8 has a plurality of thread guide modules, the modules 20′, 20″, 20′″ and 20′^v being arranged successively in the circumferential direction. In FIG. 3, a shedding comb 40 can also be seen, which is assigned to an inner ring and the configuration and functioning of which are described in detail later. A thread guide 21 can be displaced to and fro or positioned along the drum axis in the direction of the arrow e. The movement of the thread guide 21 may take place by means of a traction mechanism 33. Other means for moving the thread guide 21 may, of course, also be envisaged, such as, for example, pneumatic or hydraulic systems.

An individual thread guide module 20 is described in somewhat more detail with reference to FIGS. 4 to 6. The module has a holding plate 32, to which a mechanism unit 33 and a clamping/cutting unit 22 are attached. The mechanism unit has a traction mechanism with a toothed belt 29. The toothed belt can be driven via a thread guide drive 34 which is preferably a stepping motor. Fastened to one of the two parallel toothed belt strands is a thread guide 21 which can cover a thread guide distance FS in the direction of the arrow e. In the position of rest RS, the thread guide 21 is set back behind the clamping/cutting unit. The clamping/cutting unit 22 is arranged on a lifting slide 26 which is mounted displaceably in a guide 35. The drive means is in this case a pneumatic pressure medium cylinder 28.

The clamping/cutting unit has a double lever arm 25 which is articulated on the lifting slide 26 and the upper lever arm of which can be activated via a pneumatic pressure medium cylinder 27. The actual cutting device 24 is formed on the lower lever arm by a cutting edge. Directly behind the cutting plane lies a clamping point 23 which can likewise be activated via the double lever arm 25.

The working thread supplied or the stock thread 18/19 is introduced via a thread guide tube 36 which issues on the side of the double lever arm above the clamping point 23 in such a way that the thread lies on the thread guide distance of the thread guide 21. The thread guide has a notch or flute which prevents the thread from slipping away.

For a clearer understanding of the following functional description of the thread guide module 20, the inner thread driver 30 assigned to the drum is also illustrated in FIG. 4b. Due to means which are not illustrated in any more detail here, this inner thread driver is capable of clampingly picking up and carrying along a thread which is tensioned in the correct position.

As long as a thread is clamped to a thread guide module in the initial position illustrated in FIG. 5, it serves as a stock thread 19 which can be incorporated at any time as a working thread into the warping process in order to form a strip. For this purpose, according to FIGS. 7a and 7b, the thread guide 21 is activated so that it covers part of the thread guide distance FS and first assumes a thread take-up position FM. The lifting slide 26 is in this case already in the lowered position also illustrated in FIG. 5. The thread follow-up required for reaching the thread take-up position FM is drawn off via the thread guide tube 36. The rotational movement of the drum is coordinated with the movement of the thread guide 21 in such a way that, immediately after the thread take-up position FM is reached, the lower thread driver 33 carries along this and any other working thread of the present lap.

Immediately after the thread has been reliably picked up, the clamping point 23 is released, so that the working thread is drawn off by the circumferential speed of the inner thread driver 30. This situation is illustrated in FIGS. 8a and 8b. Up to this time point, all the active thread guide modules on the thread selection device operate simultaneously.

After this, according to FIGS. 9a and 9b, the thread guide 21 is moved a little further along the thread guide distance FS, in order to read in the thread into a shedding comb 40 for beating up a lease. This shedding operation is described in more detail later. The shedding comb for a lease has comb ends 42 which are forked in a U-shaped manner and in which an individual working thread can be deposited in each case. Threads may likewise be deposited between the individual comb ends 42. As illustrated symbolically in FIG. 9a, each thread guide 21a, 21b, 21c, etc. of thread guide modules following in the circumferential direction is then moved, in order, exactly to an extent such that a working thread is in each case deposited alternately on a comb end and between a comb end. After the beating up of the lease and after the introduction of a dividing element in the way also described below, all the active thread guides 21, 21a, 21b, 21c etc. move their respective working threads into the actual winding position of the strip 17, the width of which is clearly substantially smaller than the thread strip width reading in onto the shedding comb 40. The thread guides 21 then maintain their relative position with respect to one another until the end of the lap is reached, the entire thread selection device being moved on the warping slide.

As soon as the end of a strip lap is reached and as soon as leases are also formed there by similar means, all the active thread guides 21 move once again to an outer thread take-up position FM, in which all the working threads 18 are transferred to an outer thread driver 31 or are carried along by the latter. This outer thread driver is assigned to an outer ring 14 which surrounds the drum concentrically and corotates synchronously with the drum and which is illustrated merely symbolically in FIGS. 10a/10b. This “gathering” of the threads takes place in order to prepare for the cutting operation which is illustrated in FIGS. 11a/11b.

The lifting slide 26 is in this case moved on each thread guide module 20 into the upper end position, so that the clamping point 23 can pick up the drawn-off thread. The cutting device 24 is activated virtually simultaneously, the working thread 18 just processed being freed from the thread guide 21 and at the same time being held in a position of readiness as a stock thread 19 at the clamping point.

As is evident from FIG. 12, the means for beating up a lease at the start of a lap are arranged on the inner ring 12. The situation illustrated in FIG. 12 corresponds in this case approximately to that according to FIG. 9, threads which lie next to one another being read in alternately into shedding combs 40a, 40b arranged one behind the other. The inner thread driver is again indicated symbolically by 30. By the shedding combs being wound over alternately, a lease 50 with an open shed 51, into which a dividing element can be introduced, is clearly formed. Sizing division may also take place in about the same way. In contrast to leasing, for sizing division a multiplicity of shedding combs arranged one behind the other must be provided. Furthermore, the shedding combs are designed differently for sizing division (see, in this respect, FIGS. 28a and 28b).

Further details of a shedding means are evident from FIGS. 13 and 14. The curved shedding comb 40 consisting, for example, of plastic is fastened to a rotatable comb shank 41. A crossing rod 43 is arranged displaceably parallel to the comb shank. A pincer-like sleeve mounting 45 which clampingly grasps a dividing cord sleeve 44 is provided at the end of the prolonged comb shank 41. The approximately cylindrical dividing cord sleeve has a dividing cord spindle 46 which is screwed centrically into the dividing cord sleeve, so that an open annular gap 55 remains. A suitable dividing cord 49 is wound on the dividing cord spindle 46 and can be drawn off via the annular gap 55. The dividing cord sleeve 44 has, on the side facing the end face of the crossing rod 43, a connection element 47 to which the crossing rod 43 and the dividing cord sleeve 44 can be coupled.

The extended crossing rod 43 thus grips the dividing cord sleeve 44 which is fixed in the sleeve mounting 45 and, moreover, has about the same outside diameter as the crossing rod. The sleeve mounting 45 is subsequently opened, so that the entire circumferential region of the dividing cord sleeve 44 is exposed. This makes it possible to strip off the divided composite thread structure from the crossing rod 43 onto the drawn-off dividing cord 49.

This purpose is served by a thread stripper 48 which is illustrated in FIG. 15a and which is displaceable in the direction toward the dividing cord sleeve 44. FIG. 15a/15b show a shedding comb 40 in the position of readiness, that is to say with comb ends 42 projecting away radially outward. The crossing rod 43 is also retracted, so that, according to FIG. 16, the shedding comb can be wound over. In this case, the upper threads 53 in each case lie in the U-shaped comb ends 42 and the lower threads 52 lie between the comb ends directly on the comb shank 41. The distance between the lower and the upper threads forms the open shed 51. Depending on the strip width of the subsequent warping strip, the entire shedding comb or only a portion of this is wound over.

As soon as all the active working threads have been read in into the shedding comb, according to FIG. 17 the crossing rod 43 is extended and the shedding comb 40 subsequently rotated back into its radially inner position of rest.

This situation is illustrated in FIG. 18b. The upper threads 53 then rest directly on the crossing rod 43 and the lower threads 52 rest, as before, on the comb shank 41. The crossing rod 43 has gripped the dividing cord sleeve 44 and the end face, and the latter is freed from the sleeve mounting 45. Then, according to FIG. 19, the thread stripper 48 can be advanced, the latter stripping off the lower and upper threads 52/53 beyond the dividing cord sleeve 44 onto the dividing cord 49. The thread stripper 48 subsequently moves back again and the shedding comb 40 remains in this standby position according to FIG. 20 until it is rotated out for new shedding.

Shedding at the end of a lap takes place by similar means to those at the lap start, that is to say likewise by means of shedding combs. As already mentioned initially, these shedding combs are assigned to the outer ring 14, the diameter of which is dimensioned such that it is larger than the largest possible lap diameter. Contrary to the situation at the lap start, however, the dividing element is not a dividing cord, but a flexible dividing band introduced into the open shed, the design of the shed dividing means and the method steps not being the same as on the inside. According to FIGS. 21a/21b, a curved shedding comb 40 with comb ends 42 is likewise arranged on a comb shank 41. The flexible dividing band 54 with its angled end is arranged beneath the comb shank 41 and can be advanced from the inside of the drum. An upper crossing rod 56 can likewise be extended parallel to the comb shank 41. Moreover, a stripping sleeve 57 is provided which surrounds the entire crossing rod 56. In the initial position illustrated, once again, lower threads 52 and upper threads 53 are read in into the shedding comb 40, that is to say the thread guides 21 (FIG. 9a) assigned to each thread ensure that the threads assume the correct winding-over position.

According to FIG. 22, the reading in process is concluded and the crossing rod 56 is moved into the open shed 51. Subsequently, according to FIG. 23, the comb shank 41 is turned away, so that the upper threads 53 lie on the crossing rod 56 and the lower threads 52 lie on the comb shank 41.

In a next step according to FIG. 24, the stripping sleeve 57 is extended, the lower threads 52 falling onto the dividing band 54. By contrast, the upper threads 53 initially still lie on the end of the crossing rod 56. The end of the crossing rod is in this case approximately in alignment with the angled end of the dividing band 54.

As soon as the stripping sleeve 57 covers the last travel distance, the upper threads 53 fall onto the finished lap, but outside the dividing band 54 (FIG. 25). Consequently, the dividing element is introduced and can be advanced by the amount of a lap width in order to form a division on the next following lap. The shedding comb 40 is again rotated into the active position for shedding, and the crossing rod 56 and stripping sleeve 57 are retracted into the initial position (FIG. 26). Of course, the method described with reference to FIGS. 21a/21b to 26a/26b may also be adopted at the lap start or on the inner ring.

A complete winding sequence is described below with reference to the diagrammatic illustration according to FIG. 27. The diagram shows, from the bottom upward, the individual winding sequences, specifically with a viewing direction at right angles to the drum. In the upper third of the figure, the viewing direction runs tangentially to the warping drum 2 with the cylindrical portion 3 and with the conical portion 4, and also with an already finished lap 37. The lower two thirds of the illustration show virtually a development of the drum casing in the various operating sequences, the angular position of the drum being indicated on the right.

A winding process commences with the feed phase 60, in which, as described above, the thread selection device 8 transfers the working threads 18 to the drum with the aid of the active thread guides 21A and brings them into the correct relative position. Altogether 6 active thread guides 21A are illustrated in the diagram. In the case of two passive thread guides 21P, the corresponding thread guide modules remain in their neutral position of readiness in which the stock threads 19 rest.

In the lower winding-over phase 61, the working threads 18 are read in into the lower shedding combs 40 with the aid of the active thread guides 21A. As described above, the divided threads are pushed onto the dividing cord and the active thread guides 21A subsequently move the threads together to the strip width B of the warping strip 17, on the one hand, and, at the same time, to the left to the foot point 38 of the conical portion 4, on the other hand. At the end of this process, the drum has executed a revolution of 360°.

This is then followed by the actual winding phase 62 for building the lap 37, and, depending on the thread quality, a sufficient number of drum revolutions N×360° to ensure that the desired lap height H is reached are required.

After the lap 37 is finished, this is followed by the upper winding-over phase 63 for reading in the threads into the upper shedding combs 40 on the outer ring 14. For this purpose, the active thread guides 21A move even further to the left and at the same time apart from one another again to the reading in width. For shedding and for advancing the dividing band into the open sheds, the drum again requires a full revolution of 360°.

The thread guides 21A subsequently move together into a row, in order to transfer the working threads 18 jointly to the outer thread driver 31, the thread guide modules cutting the working threads and, in turn, gripping them clampingly. This action is illustrated as the upper feed phase 64.

Without the drum being stopped, the next lap can then be wound in the same way, in which other threads are possibly called up on the thread selection device 8. Clearly, in this case, the inner ring 12, the outer ring 14 and also the thread selection device 8 move to the right by the amount of a strip width B.

FIGS. 28 a and 28b illustrate shedding combs for sizing division. With the aid of a first shedding comb 40′ (FIG. 28a), in each case a first thread is deposited into a comb end 42′ arranged at the start of the comb. Further comb ends are arranged at predetermined periodic intervals from one another, in each case individual threads forming a shed. A dividing element, for example a crossing rod, can be guided through this shed. A next second shedding comb 40″ (FIG. 28b) following the first shedding comb has comb ends 42″ for a second thread or second threads, the comb ends of the first shedding comb being offset with respect to the first shedding comb by the amount of one thread location. The next shedding combs are designed similarly, that is to say, in the case of the third shedding comb, the respective comb ends would be offset by the amount of one further location, etc. Consequently, in the example according to FIGS. 28a/28b, seven shedding combs would be necessary for sizing division.
