Abstract

The invention relates to a method for winding a ribbon (17), which is comprised of a number of parallel threads (18), onto a rotating warping drum (2), during which a ribbon lap (66) is moved in a forward direction (e) with the aid of conveyor belts (70), which are placed on the peripheral area of the winding body (2), after the ribbon lap (66) has been constructed. The winding position of each individual thread on the warping drum (2) is established during the winding process with a thread guide (21) assigned to this thread.

Description

Method and device for winding a strip consisting of a plurality of threads onto a winding body rotating around a rotation axis

The invention relates to a method and an apparatus for winding a band consisting of a plurality of threads onto a winding body rotating about a rotation axis. Derarti¬ ge methods and devices are used for example in textile technology in the weaving preparation for archiving the We¬ berkette. But winding processes are also in other areas such. required in the wire industry. The present invention is therefore not restricted to textile application purposes and the term "threads" covers any elongated, windable element, regardless of the cross-sectional shape or of the material.

In the known water treatment plants with rotating warping drums, a group of yarns is drawn off a creel, which is arranged in relation to the yarn sheet perpendicular to the drum axis. Such an arrangement requires a relatively large amount of space. The band or winding structure takes place via a cutting carriage which can be moved along the drum axis. Next, the known Schärverfahren particular for the production of so-called pattern chains or short chains, in which the band composition must be changed frequently, little suitable ge, since each conversion of the band composition requires a machine standstill Ma¬. This significantly delays the work process.

It is therefore an object of the invention to avoid the disadvantages of the known Be, in particular to provide a method and a Vor¬ direction of the aforementioned type, which allows rapid tape change or different tape compositions with relatively small footprint. Furthermore, a high process reliability should be ensured. This task 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 11.

In a method for winding a plurality of threads for producing one or more band windings on a winding body rotating around a rotation axis, the band windings are moved parallel to the axis of rotation (hereinafter axis-parallel) by means of a conveying device arranged on the peripheral area of the winding body in a forward direction a first end face to a second end face of the winding body moves be¬.

The movement of the threads or the tape winding is advantageously carried out by means of axially parallel axial conveyors. Such axial conveyors include, for example, endless chains or belts. Thus, in particular, transport belts, as are known in connection with water treatment plants with rotatably held Trom¬ meln (as described for example in DE-Al-9605924) can be used.

Advantageously, the conveyor device is moved discontinuously to produce belt windings. In particular, the conveying device can be used to further transport entire band wraps in order to enable the construction of new or next band wraps. The conveyor is advantageous during a winding process for a tape roll in Still¬ stood. In other words, the conveyor remains at rest relative to the axis of rotation. Of course, the conveyor rotates continuously with the winding body.

After the tape reel has been constructed, the conveying device drives the tape reel in a particularly advantageous manner around a predetermined conveying position. stretch in forward direction. This conveyor line preferably corresponds to the bandwidth of a next band or bandwrap or last wound band or band lap. Thus, in an advantageous manner on the winding body a plurality of tape rolls with the same or different yarn repeat can be wound on one another or next to one another, wherein the winding body rotates continuously.

Alternatively to the discontinuous movement of the conveying device, however, it would also be conceivable to move individual threads continuously with the aid of the conveying device. In this way, a pattern string or a plurality of pattern strings could be wound with individual juxtaposed ribbons.

It is advantageous if the threads are pulled off by a creel arranged in an extension of the axis of rotation in the region of the first end face of the wedge body with preferably rotatable coil suspensions. By this arrangement, for example, an entire sewage treatment plant is arranged substantially in a line. An advantage is that the creel can be easily refilled or converted.

It is furthermore advantageous if the winding position of a respective thread on the winding body for the winding process is determined by a thread guide associated with the thread, which can be adjusted axially parallel from a rest position into a working position. As a result of the axially parallel displacement, the thread guide can be moved precisely into a winding position for the respective thread. In addition to the axis-parallel movement, the thread guide could also be moved in the radial direction.

The threads are preferably used as a group of threads from a bobbin ter to one in the region of the first end side of the bobbin arranged in the winding area yarn selection with a plurality of yarn guides. Some of these threads are withdrawn via the thread guide as working threads and form the tape or the tape roll, while the remaining threads are held as a clamping threads on the thread selection device clamping. The clamping is preferably carried out by means of each nip nip. Such a yarn selection device makes it possible in a simple manner to perform a tape change in a continuously rotating winding body. In particular, it is thus possible to produce a plurality of band wraps having different compositions with regard to the type of thread, the sequence and / or the number of threads. This procedure makes it possible to carry out a band change in a continuously rotating winding body in a simple way, which in turn considerably accelerates the working process.

After at least one first winding sequence for the first tape roll, the working threads of the wound tape can be separated and clamped to the yarn selection device. Thus, in at least a second winding sequence, the working threads of the tape may have a different composition than during the first winding sequence. It is vorteil¬ haft when after the construction of a tape winding all work threads are separated from the thread guide. Thus, all available threads could be used as work threads to produce a next tape roll. It would also be conceivable that some of the work threads are not separated after each lap sequence. Unseparated work threads could be provided for a next tape roll. The composition of the band can also be the same for several adjacent coils. Finally, it would also be conceivable that the threads of a band are not severed after each winding sequence, but that the band is guided at the end of a roll directly to the beginning of an adjacent roll. A yarn transfer taking place at full bobbin rotation can be achieved particularly advantageously if the selected work threads are first stretched by means of the yarn guides into a driving position over the bobbin in which they are stretched freely between the yarn guides and one clamping point approximately parallel to the axis of rotation are and that in the course of a winding body rotation all working threads in the driving position of one of the winding body associated inne ren Fadenmitnehmer sequentially detected and then separated from the nip. After disconnecting from the Klemm¬ the thread guide can be driven with their work threads in the tape winding position on bandwidth. This flie¬ ing transfer of the clamped stock threads as work threads on the bobbin can be done at high speeds and in¬ nerhalb a single bobbin rotation.

After the construction of a ribbon wound, in turn all working threads can be sequentially grasped by an outer thread follower synchronously rotating with the winding body and then clamped again by the clamping point and at the same time separated from the leader. This is practically a flying return of the work threads in the waiting position at the terminal points.

With the aid of at least one axially parallel displaceable Stütz¬ element, a first tape roll can be supported on one side during the winding process. In this way, a stable tape winding construction is ensured. It is particularly advantageous if the support element is moved axially parallel in synchronism with the tape winding transport. The angular position of the supporting portion of the support member may possibly be changed or adjusted.

As already described above, not all working threads need to be separated after the construction of a tape roll. So For example, threads which are temporarily not needed can be taken out of the winding process for winding onto the winding body in such a way that the unnecessary threads are wound onto an auxiliary winding body which rotates synchronously or asynchronously with the winding body.

At the beginning and / or at the end of a band wound, the threads, in particular the working threads, are moved axially parallel to the thread guide in the forward direction or in the opposite direction to the direction of forming a crosshair or for sizing on or under a Peripheral region of the winding body arranged, axially parallel Tei¬ lungselement stored. In this way, threads can be easily separated from each other with rotating bobbin. The yarn guides only have to be moved back and forth between two positions. These positions are advantageously predetermined by a selection element such as a hook. Such a thread pitching method, in which threads are arranged on or under a partial bar running axially parallel in the forward direction or in the opposite direction by achsparal¬ leles moving the thread guide, can also ren for conventional Verfah¬ with rotating bobbin be provided. For the formation of a crosshair or for the sizing division, it would therefore also be possible to use wound bodies without conveying devices arranged thereon. A movement or shifting of the threads or band wound takes place in this case only via the thread guides.

A further aspect of the invention relates to a device for winding a strip consisting of a plurality of threads and / or for producing ribbon windings onto a wound body rotatable about an axis of rotation with a first and a second end face. On the circumference of the winding body is a conveyor for axially parallel movement of the on Conveyor stored filaments arranged. The conveying device allows the transport of threads or band windings in a forward direction from the first end side to the second end side of the winding body. The winding body is preferably an approximately cylindrical warping drum. But also warping drums with a cone-shaped section are conceivable.

The conveyor may have at least one axially parallel ver¬ running conveyor belt. The transport belts preferably extend over the entire length of the bobbin defined by the two end faces. The transport belts can be designed as endless belts or belts. Of course, other axial conveyors could be provided.

For lateral stabilization of the tape roll, a Stütz¬ element can be provided. The support member is advantageously associated with the conveyor and together with this axially parallel displaced. Thus, simultaneously tape roll and support element can be transported. For example, the support element may be a support ring arranged around the circumference of the wedge body, which is connected, for example, to one or more transport belts. However, it is also conceivable that the support element has individual support wedges, which are each associated with a transport belt.

In one embodiment, dividing elements extending axially parallel to the circumference of the winding body are arranged, for example, partial rods for forming a crosshair and / or for sizing. The partial rods are preferably cylindrical in cross-section, flattened partial bands are likewise conceivable. One end of the dividing element is advantageously connected in the region of the second end face of the winding body fixed thereto. The other end of the dividing element in the region of the first end face of the wound body is exposed, so that threads can be separated from one another by the partial rod and with the aid of axially parallel displaceable thread guides. Of course, it would be conceivable to use this type of thread pitch also in conventional devices in which not every single thread is deposited over an individual leader.

Under certain circumstances, the dividing elements could have conveying devices for axially parallel displacement of deposited filaments or band wounds. These could be formed approximately the same as the previously described transport belt. In particular, these conveying devices could be coupled to the transport belts via transfer means or could be displaced synchronously with these axially parallel.

A bobbin with partial bars could be constructed as follows: the periphery of the bobbin in the front view has opposite dividing sections, wherein a dividing section for partial bars for cross-hair formation and the opposite dividing section for sizing division vor¬ seen. These division sections could be designed as essentially straight secant sections. Between the two division sections are Umfangs¬ sections on which conveyors, in particular conveyor belts are arranged.

Of course, a winding body could indeed be equipped with dividing elements, but not with a conveying device such as transport belts. Accordingly, the described division elements could also be provided for conventional rotary drivable warping drums and in particular also for warping drums of cone warping machines. It is conceivable, in particular, that such an arrangement is also used for warping drums which are intended for a cone warping machine. The dividing element preferably have a radially outwardly extending selection element at its free end. With the aid of such selection elements, a thread can be deposited on the winding body either on or under the dividing element in a simple manner. For example, a hook or another tapered element could be provided as the selection element.

It is also conceivable to provide a dividing element with movable selection elements. For example, the selection element, in particular the mentioned hook or an anterior tip, could be adjustable or pivotable parallel to the axis. In this way you could possibly optimize the thread pitch.

It is advantageous if, for each individual thread, a thread guide is arranged in the circumferential region of the winding body, which can be displaced axially parallel between two positions in relation to the free end or the selection element of a partial rod, such that the respective thread is at or below the thread Part bar can be placed on the winding body. Particularly preferred is the winding position on the winding body by the Fa¬ denführer over the thread in question auf¬ wound up as working thread, can be fixed.

The thread guides can be successively arranged in an arcuate manner over the wedge body and can be adjusted parallel to the axis from a rest position to at least one working position.

In a further embodiment, the yarn guides are part of a yarn selection device which has one nip and one yarn guide for a plurality of yarns, with some of these yarns being removable over the yarn guides as the working yarns forming the band, while the yarns remaining threads can be fixed as supply threads at clamping points in Warte¬ position.

Depending on a thread guide and a clamping point can be assigned to a Fa¬ denführermodul, the module an indi vidual drive for adjusting the thread guide and a be¬ movable clamping cutting unit with a clamping point for clamping the thread and with a cutting device for separating of the thread. The cutting and clamping of the threads er¬ follows in this way virtually the same location, making the freilie¬ ing thread change is possible with rotating bobbin.

The drive of the yarn guide module preferably includes a traction mechanism with a traction means, in particular with a toothed belt, on which the yarn guide is arranged such that the yarn guide is movable approximately parallel to the axis on a yarn guide path. The drive could alternatively be provided with a push rod.

A clamping cutting unit can be movable approximately at right angles to the guide path such that the clamping point is displaceable relative to the winding body circumference between a radially outer rest position and a radially inner thread transfer position.

It is advantageous if, on the winding body, an inner thread take-up member for grasping and taking along all the threads of the band to be wound is arranged at the beginning of the roll in the area of the first end face of the winding body. As an alternative, however, it would also be possible to provide a plurality of thread drivers, which detect and take along individual or a certain number of threads to be wound.

The inner thread driver can be displaceable parallel to the axis of rotation of the wedge body, wherein the inner thread driver is arranged on a linear guide in the winding surface.

Furthermore, an outer thread driver rotating on an outer circulating track in synchronism with the winding body can be provided for temporarily detecting all the threads of a wound strip.

These outer thread drivers can be displaceable axially parallel with respect to the winding body, the outer thread carrier being arranged on a rotatably drivable outer ring surrounding the winding body.

In a further embodiment, a synchronous or asynchronous and co-rotating auxiliary winding body is arranged on the first end face of the winding body. The auxiliary winding body preferably has the same axis of rotation as the winding body and serves for winding up a yarn which is not required temporarily in a warping operation. This case does not have to be cut off. If this thread is needed again for the warping process, then it can be used quickly by moving the corresponding thread guide back into the warping process.

It is advantageous if the diameter of the auxiliary winding body is significantly smaller compared to the diameter of the wound body, in particular at least a factor of 5, more preferably by a factor of 10. In this way, in comparison to the winding process on the winding body on the Auxiliary winding body wound up relatively little thread material.

As can be seen from FIG. 1, a warping machine designated as a whole by 1 consists essentially of a warping drum 2 as a winding body with an approximately cylindrical section 3. The warping drum 2 is rotatable about a winding body or drum axis 6 in a frame 5 stored. In the area of the first end face 67 of the warping drum 2, a thread selector 8 is arranged fixedly. The thread selection device contains a multiplicity of thread guides 21, which are arranged distributed successively in the area of the circumference of the drum at the first end face 67 of the warping drum. The thread guides can be moved axially parallel (that is to say parallel to the axis of rotation 6). A creel 69 is located in the extension of the axis of rotation 6 of the warping drum 2 in the same line as the warping drum. From the creel 69 or from another Fa¬ denspendereinrichtung a yarn sheet 9 is withdrawn, each individual thread is guided to one of the yarn guide 21. As a creel, for example, a change gate or other creel system could be provided with fixed Spulenauf- plug-outs. Suitable devices, such as Thread brakes ensure that the threads always stay taut.

It can further be seen from FIG. 1 that in the peripheral region of the warping drum 2 conveyors for axially parallel movement of threads and / or band windings are arranged in the forward direction (the forward direction is represented by an arrow e). As conveyor could be provided, for example, distributed over the circumference conveyor belt 70 with endless belts or endless belts. The transport belt 70 is movable via drive means (not shown). Furthermore, dividing elements in the form of partial bars 71 are shown in FIG. Such dividing elements are used to divide threads, for example, for sizing or Faden¬ cross-formation. The partial bars 71 have a free end on one side. On the opposite side, ie in the region of the second end face 68, the part rods 71 are fixedly connected to a front side end 77 of the warping drum 2. Directly adjacent to the part rods 71, conveyor belts 70 ensure that threads or band windings deposited on the warping drum 2 can simply be displaced in the direction e.

To stabilize the dividing element 70, a support ring 80 is provided between the end faces 67 and 68 and concentrically surrounds the wedge body. The support ring 80 can be moved individually parallel to the axis. It is advantageous, however, if the support ring 80 is movable over the conveyor belt 70. Thus, the support ring 14 could be transported at the same time as the wound threads or tape roll in the e direction. At the same time, however, the support ring 80 also serves to support a side of a tape roll.

FIG. 2 shows a possible arrangement of transport belts 70 and dividing elements 71. The dividing elements 71 are arranged on opposite sections 72 and 73, these sections being in the form of straight secant sections. On the one hand, here in section 72, dividing elements are provided for crosshairs. On the opposite side, ie on the section 73 dividing elements are provided for sizing division. Between the sections 72 and 73, conveying devices in the form of carrying straps 70 are arranged on the respective circumferential section 74 or 75. Evidently, the peripheral sections 74 and 75 as well as the sections 72 and 73 are in the transverse direction. curved or circular. It is quite conceivable that the dividing elements 71 could also be located on arcuate or circular sections. Further, in order to ensure a safe transport away from threads or band wraps between the individual dividing elements 71, further conveying devices such as transport belts could be provided in each case.

Another embodiment of a warping drum 2 in the end view is shown in FIG. The dividing elements 71 are arranged on opposite sections 72 and 73, these sections being in the form of straight secant sections.

In Figure 4, the cross section of a warping machine 1 is shown schematically. In Figure 4, both dividing elements 71 'and 71' 'and conveyor belts 70 can be seen. However, this does not mean that the dividing elements on the one hand and the conveying device on the other hand must lie on the same radial plane. Advantageously, dividing elements and transport belts are arranged offset to each other on the circumference of the warping drum 2.

Inner and outer dividing elements 71 'and 71 "are arranged above the transport belt. The first dividing element 71 'serves to divide the thread at the beginning of a roll. The second dividing element 71 ", which is arranged at a greater radial distance from the axis of rotation 6, serves to divide the thread at the end of a coil. It is conceivable that in particular the outer dividing element 71 "could be displaceable in the radial direction r. This may be required for different tape winding thicknesses. The dividing elements are designed as partial rods and have hooks 76 which are each directed radially outwards. These hooks 76 form selection elements, with the help of threads can be separated from each other easier. FIG. 4 shows a first band wrap 66. This band is produced essentially as follows: With the aid of thread guides 21, threads 18 are laid down in a band-wise manner onto the peripheral region of the warping drum 2. (For details on the construction and the function of the thread catcher or thread selection device, see the following FIGS. 7a to 13). During the entire winding process for building up the band winding 66, the transport belts stop (of course, however, the warping drum 2 remains in rotation during the entire process). After the band winding 66 has been constructed, it is moved by means of the support belts 70 in the direction e about a conveying path B (to the left). This conveyor line B corresponds to the bandwidth of the next (here second) tape roll. The direction of rotation is indicated by an arcuate arrow in the region of the left angeord¬ Neten role. The thread pitch at the beginning or at the end of the tape roll is explained in more detail with reference to the following FIG.

The tape roll 66 is supported on one side by means of a support wedge 79. A support wedge 79 is in each case associated with a support belt 70 and firmly connected thereto. Thus, the support wedge 79 can be transported together with the support belt 70 in the e direction. At most, the angular position of the ab¬ supporting section of the supporting wedge 79 could be adapted for example to Fa¬ type and / or operation. Instead of einzel¬ ner support wedges but could of course provide the support ring shown in Figure 1.

The warping drum 2 is rotatably mounted on both sides via rollers. For example, spherical or roller bearings are used as bearings. At the first end face 67, a synchronously co-rotating with the warping drum 2 auxiliary winding body 78 is arranged with the same axis of rotation 6. The auxiliary winding body 78 is used for disgusting for a warping temporarily unneeded threads.

Figure 5 shows how crosshairs can be formed. Dividing elements 71: FKE1, FKE2, FKE3 divide the threads represented by © to (D) in such a way that they lie alternately on or below the dividing elements 71. In order to deposit a thread on, for example, a partial bar 71, it must A thread guide 21 may be positioned on the left or in the position OPEN The thread driver 21 is located on the right or in a position UNT for depositing a thread under the part rod. The positions UP and DOWN are provided by the selection element 76 The crosshairs are formed when the drum is rotating

(indicated by the direction of the arrow a). The laying of the threads for crosshairs can be done in the same way for both the inner and the outer partition element

(see Figure 4) are applied.

The sizing is done essentially in a similar manner as described in FIG. Here, too, essentially only the thread driver 21 has to be moved back and forth between two positions (AUF, UNT) such that the threads can be deposited on or under the dividing elements 71. As can be seen in FIGS. 6a and 6b, using the example of a "size 7 division", the threads (represented by © to ®) are no longer stored alternately, but only individually abge¬ on a first size distribution element STEL inserted, the remaining threads ((D to ®) under the Schlich¬ teteilungselement STEL stored. the second thread ^(D is then deposited on the second size distribution element STE2 is for the subsequent threads proceed in an analogous manner Figure 6b shows the same procedure for a next band (Threads 8 in a circle ff). The number Schlichteteilungsele¬ elements is given by the number of threads of a band.

FIG. 7a shows a perspective partial view of a thread selection device 8 of a warping machine. The Fadenwähleinrich¬ device 8 has a plurality of yarn guide modules, wherein the modules 20 ', 20'',20''' and 20 ' ^v are arranged sequentially along the ring. A yarn guide 21 can be moved or positioned along the drum axis in the direction of the arrow e or -e. The movement of the thread guide 21 can take place with a traction mechanism 33. Of course, other means for moving the thread guide 21 are conceivable, such as pneumatic or hydraulic systems.

A single yarn guide module 20 will be described in more detail below with reference to FIGS. 7b and 8 to 6. The module has a holding plate 32, to which a gear unit 33 and a clamping cutting unit 22 are fastened. The toothed belt can be driven via a thread guide drive 34, which is preferably a stepper motor. At one of the two parallel Zahnrie¬ mentrums a yarn guide 21 is attached, the axis parallel in the direction of arrow e can cover a yarn guide stretch FS. In the rest position RS, the yarn guide 21 is 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 driving means used here is a pneumatic pressure medium cylinder 28.

The clamping cutting unit has a double lever arm 25, which is articulated on the lifting carriage 26 and whose upper lever arm can be activated by means of a pneumatic pressure medium cylinder 27. The actual cutting device 24 is at the bottom Lever arm formed 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 better understanding of the subsequent functional description of the yarn guide module 20, the inner thread driver 30 associated with the drum is also shown in FIG. 7b. 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 FIG. 8 on a thread guide module, it serves as a stock thread 19, which can be included at any time as a working thread in the warping process to form a strip. For this purpose, according to FIGS. 10 and 11, the thread guide 21 is activated, so that it covers a part of the thread guide section FS and first assumes a thread take-up position FM. The lifting carriage 26 is already in the lowered position shown in FIG. The yarn feed required to achieve the thread take-up position FM is drawn off via the yarn guide tube 36. The rotation movement of the drum is matched to the movement of the yarn guide 21 in such a way that, immediately after reaching the thread take-up position FM, the lower yarn driver 33 entrains this and any other working yarn of the current roll. Immediately after the secure detection of the thread, the nip 23 is released, so that the working thread can be withdrawn at the peripheral speed of the inner thread driver 30. Until then, all active thread guide modules on the thread selection device are working simultaneously. Afterwards, all active yarn guides carry out the method of division described with reference to FIGS. 5 and / or FIGS. 6a / 6b.

After forming the reticle and / or the sizing division drive in the manner described below al¬ le active yarn guide 21, 21a, 21b, 21c, etc. on the their respective work threads on the actual winding position of the tape. The yarn guides 21 maintain their relative position zu¬ each other now until the end of the tape roll is reached. During the winding structure, all thread guides move synchronously in the axis-parallel direction e. If the winding length is reached, the entire group of yarns is pushed away by the conveyor belt by one band width from the color selector and the yarn guides return to their initial position. Instead of the axis-parallel displacement of the conveyor belt, it is also conceivable that instead the whole yarn selection device is moved in this direction. In this method, the partial rods would be pushed axially parallel by concentrically mounted rings to the next bandwidth.

At the end of a tape winding of the lifting carriage 26 is moved to each yarn guide module 20 in the upper end position, so that the nip 23 can detect the withdrawn yarn. At the same time, the cutting device 24 is activated, whereby on the one hand the working thread 18 just processed is freed from the thread guide 21 and at the same time held in the standby position as a supply thread 19 at the nip.
