Description

Method for operating a winding device

Technical Field

The invention relates to a method for operating a winding device for producing a yarn bobbin, comprising a yarn creel for rotatably holding the winding bobbin, a groove roller arranged upstream of the winding bobbin in the yarn direction for positioning the yarn when winding to the winding bobbin to produce the yarn bobbin, and a supply device for supplying the yarn to be wound to the groove roller, wherein the yarn is firstly supplied to the groove roller under tension of the yarn by means of the supply device, and then is wound onto the winding bobbin arranged on the groove roller, and the groove of the groove roller determines the position of the yarn on the winding bobbin. The invention also relates to a corresponding winding device for producing a yarn bobbin.

Background

A workstation of a textile machine for producing cross-wound bobbins is known from DE102014009203a1, which has a rotatably mounted creel for rotatably holding the bobbins, rollers on which the bobbins are placed during winding, and a thread suction device which can receive a negative pressure as required for receiving a thread which falls onto the surface of the bobbins after the winding has been interrupted. The thread suction device is a stationary device having a movably mounted upper rotary plate and a movably mounted lower rotary plate, wherein each rotary plate is arranged around the roller, so that they form a suction nozzle contour which can receive a negative pressure in the surface area of the winding bobbin for receiving the upper thread.

However, in the methods known from the prior art for operating a winding device, when producing a yarn package, a faulty deposition of the yarn on the package can occur, which reduces the quality of the yarn package and can cause problems when it is subsequently used. In particular in the region of the bobbin edge, the thread can erroneously pass through parts of the side edges of the bobbin, wherein a back-off can lead to an uneven unwinding of the thread from the bobbin.

Disclosure of Invention

One aspect of the invention therefore relates to a method for operating a winding device for producing a yarn bobbin, comprising a yarn creel, which is mounted in a particularly pivotable manner, for rotatably holding the winding bobbin, grooved rollers, which are arranged upstream of the winding bobbin in the yarn direction, for positioning the yarn when winding up to the winding bobbin for producing the yarn bobbin, and a supply device for supplying the yarn to be wound to the grooved rollers, the yarn being supplied to the grooved rollers first under tension by means of the supply device, and subsequently being wound onto the winding bobbin provided on the grooved rollers, the grooves in the grooved rollers determining the position of the yarn on the winding bobbin.

The method according to the invention is characterized in that, in order to prevent the yarn from being erroneously deposited on the winding bobbin, in particular from being detached in an end region of the yarn bobbin, a yarn guide which extends across the width of the grooved roller and is mounted so as to be pivotable parallel to the surface of the grooved roller can be moved between the yarn to be wound and the grooved roller in such a way that the yarn is at least partially lifted out of the groove of the grooved roller and is pulled from the edge region of the yarn bobbin to the center of the yarn bobbin as a result of the yarn being tensioned.

The winding device according to the invention for producing a yarn bobbin has a yarn bobbin creel for rotatably holding the winding bobbin for winding the yarn into the yarn bobbin, a groove roller arranged upstream of the winding bobbin in the yarn direction and having a groove for positioning the yarn when winding onto the winding bobbin, and a supply device for supplying the yarn to be wound to the groove roller, wherein the supply device comprises a yarn tensioner for supplying the yarn under tension. In addition, the thread guides extending over the width of the grooved rollers are mounted pivotably parallel to the surface of the grooved rollers in order to be able to move between the thread to be wound and the grooved rollers, whereby a faulty laying of the thread on the winding bobbin can be prevented in a simple manner.

The method according to the invention thus allows, in a simple manner, the prevention of incorrect laying and the formation of a run-off edge, in particular at the edge or on the side of the thread bobbin, by the thread guided by the groove of the grooved roller at least shortly before or during the incorrect laying being lifted off the groove by means of the thread guide and guided along the thread guide towards the center of the bobbin as a result of the thread tension, so that incorrect laying at the edge of the thread bobbin is precluded. In addition, the method of the present invention does not require complicated configuration of the yarn guide device and the winding method for reducing the winding speed of the winding device.

The winding device is basically a device provided for producing a yarn bobbin from a single yarn. The winding device may be a separate component, in particular a single machine. Preferably, however, the winding device is part of a textile machine or spinning machine, in particular a rotor spinning machine. The winding device is also preferably one of a plurality of stations, in particular a plurality of identical stations, of a textile machine for producing bobbins, in particular cross-thread bobbins. Particularly preferably, the winding device is a station of an automatic winding machine, in particular an Ottokana automatic winding machine. Furthermore, such a winding device or a station having a winding device is preferably equipped with a thread take-off sensor, a thread tensioner, a clearer with thread cutting, a thread tension sensor, a thread catching nozzle and/or a waxing device, respectively.

In order to produce a yarn bobbin, the individual yarns are wound onto an initially empty bobbin until a completed, full yarn bobbin is formed. The yarn is preferably wound with a predetermined arrangement of the yarn distributed on the bobbin. The feed bobbin, which is preferably rewound into a yarn bobbin, in particular a cross-wound bobbin, for example, particularly preferably a bobbin tube which has been produced by a textile machine, such as a ring spinning machine, a rotor spinning machine or a rotor spinning machine, and has a relatively small amount of yarn material, is preferably wound up by means of a winding device or by means of each station of the textile machine which produces the yarn bobbin, which particularly preferably has a much greater amount of yarn than the feed bobbin. The yarn can be any, in particular twisted, fabric composed of fibers, in particular of any material, in particular natural fibers, such as wool or cotton, and/or plastic fibers. The yarn is preferably a yarn, a twisted yarn or the like.

The yarn is continuously supplied via the grooved roller to produce a yarn bobbin wound on a bobbin, wherein the yarn direction is the yarn moving direction during the supply. The supply device may in principle consist of any number of components or assemblies of any material. Preferably, the supply device is designed to be completely closed in order to minimize scattering of fabric dust or fibers in the environment of the winding device. The opening of the supply device, in particular of the supply device for supplying the thread, is preferably arranged centrally in the grooved roller and/or in the winding bobbin. The supply by means of the supply device is also preferably directed perpendicularly to the surface of the grooved roller.

According to the invention, the yarn supply is carried out under yarn tension. The tensioning can in principle be generated in any way. For this purpose, the thread can be tensioned mechanically, in particular by means of a thread tensioner and/or by an air flow opposite to the thread direction. The yarn winding is thus carried out counter to the yarn tension, whereby a clean and kink-free production of the bobbin is obtained.

In order to produce a yarn bobbin, the winding bobbin is held by a yarn bobbin creel, which allows the winding bobbin to rotate to wind yarn. The yarn bobbin creel is preferably mounted so as to be pivotable, the pivot axis of the yarn bobbin creel preferably extending parallel to the axis of rotation of the winding bobbin and/or of the grooved roller.

In order to determine the exact position of the thread when it is wound on the winding roller or to guide the thread during winding, the grooved roller is arranged upstream of the winding bobbin in the thread direction, in particular immediately in front of the winding bobbin, and more particularly preferably in rolling contact with the winding bobbin. The grooved roller is preferably at least as long as the winding bobbin in order to ensure a reliable guidance of the thread during winding over the entire width of the thread bobbin or of the winding bobbin.

For guiding the yarn, the grooved roller has at least one groove in the surface, in which groove the yarn to be wound is guided. If the thread is guided in a winding device by grooved rollers or their grooves, the grooved rollers force the thread to follow a known course predetermined by the groove geometry. In this case, the at least one groove preferably extends such that the yarn bobbin is wound as a cross-wound bobbin.

In order to be able to produce a cross-wound bobbin, the grooved roller preferably has a single groove which runs at an angle from one end of the grooved roller to the other end and back again, wherein a groove particularly preferably crosses several times over the surface of the grooved roller, so that individual sections of the groove are regarded as grooves running side by side over the surface. In particular, it is preferred that the groove extends in at least one direction, in particular in both directions, at a constant angle along the central longitudinal axis of the grooved roller, so that a uniform winding of the thread onto the thread bobbin is achieved.

The thread guide can be any component or any assembly, wherein the thread guide extends at least over the entire circumferential length and/or at least over the entire width of the grooved roller surface with the groove, so that the thread guide can be moved between the thread and the grooved roller, independently of the position of the thread in or on the groove, in order to lift the thread off the groove. For this purpose, the thread guide preferably has at least one flat front edge and/or a front edge arranged parallel to the grooved roller surface. It is particularly preferred that the entire yarn guide is curved at a constant distance from the surface of the grooved roller.

According to the invention, the thread guide can be pivoted in at least one section parallel to the grooved roller surface, wherein the center point or pivot axis of the pivoting movement is preferably identical to the axis of rotation of the grooved roller. The thread guide element can also preferably be moved completely into the region between the opening of the supply device for the yarn output and the region of the surface of the grooved roller which contacts the yarn. Particularly preferably, the thread guide can also be moved completely out of the region.

If the thread guide is moved between the thread to be wound leaving the supply device and the surface of the grooved roller, the thread is lifted off the groove of the grooved roller and is therefore no longer guided in one direction along the axis of rotation of the grooved roller. Accordingly, the thread is pulled in a straight line between the surface of the winding or thread bobbin and the thread opening of the supply device, in particular of the supply device, as a result of the thread tension. Since the supply device is preferably not located in the end region of the thread bobbin and more preferably not laterally offset therefrom, but is particularly preferably arranged in the central region of the thread bobbin and/or grooved roller, the thread rising out of the groove is drawn toward the center of the thread bobbin compared to the thread guided in the groove, so that incorrect laying in the edge region of the thread bobbin is avoided or eliminated.

A preferred embodiment of the method according to the invention provides that the supply takes place in a supply device in the form of a yarn channel with a closed yarn course, preferably against underpressure and/or against an air flow opposite to the yarn course, wherein the thread guide is particularly preferably part of a suction nozzle flap, which can be moved more preferably along a part of the circumference of the grooved roller, whereby advantageously for carrying out the method according to the invention the existing winding device has to be adjusted only in the region of the grooved roller by adding a hitherto unknown thread guide, so that the existing winding device can also be retrofitted without high outlay for carrying out or using the method.

In a particularly preferred embodiment, the suction nozzle guard is a lower suction nozzle guard and/or an inner suction nozzle guard, which can be moved as a lower suction nozzle guard both to the bottom side and also to the grooved roller surface in the mounted state of the winding device, and it is particularly preferred if a second, in particular upper suction nozzle guard and/or an outer suction nozzle guard arranged in the region of the grooved roller is also provided only for arrangement on the surface of the grooved roller. The inner nozzle baffle is also preferably arranged closer to the grooved roller surface than the outer nozzle baffle, wherein it is particularly preferred that the two nozzle baffles can be moved and/or arranged independently of one another and in particular also overlapping. Finally, it is preferred that one or both nozzle baffles are formed as a rotating plate. The thread guiding element and in particular the suction nozzle baffle preferably form an end element of the thread channel which is closed except for a lower opening and an upper opening.

In an advantageous development of the method according to the invention, the thread tension is generated by a thread tensioner arranged upstream of the groove roller in the thread direction on the supply device and/or the supply device is arranged centrally upstream of the groove roller in such a way that the thread lifted off the groove by means of the thread guide is pulled toward the center of the groove roller and/or toward the center of the winding bobbin, whereby the thread can be pulled toward the center of the winding bobbin in a very simple manner and without additional components during or before the incorrect laying on the winding bobbin, whereby the formation of a fray is particularly reliably prevented. For this purpose, the supply device is preferably arranged offset with respect to the center by not more than 25%, particularly preferably not more than 15%, and very particularly preferably not more than 5%, with respect to the total width of the grooved roller and/or the winding bobbin. Particularly preferably, the supply device is arranged exactly centrally.

According to a preferred embodiment of the method according to the invention, the winding bobbin is driven by friction by the grooved rollers, for which purpose the winding bobbin and the grooved rollers roll relative to one another, as a result of which the yarn bobbin formed on the winding bobbin is driven in a very simple manner, while the path speed of the yarn bobbin on the surface remains constant, so that the yarn feed speed advantageously does not have to be increased as the diameter of the yarn bobbin increases. For this purpose, the axis of rotation of the winding bobbin and/or of the winding creel is arranged parallel to the axis of rotation of the grooved roller. Particularly preferably, the grooved roller is driven by means of a drive unit, and more particularly preferably, the winding bobbin and/or the yarn creel is/are configured without a drive unit.

In general and in particular when the winding bobbin is driven by a grooved roller, it is preferred that the winding bobbin and the grooved roller are operated in opposite directions of rotation, whereby an easy transfer of the thread from the groove of the grooved roller to the surface of the winding bobbin can be achieved. Accordingly, it is also preferred that the thread guide is moved in or along the direction of rotation of the groove roller and/or counter to the direction of rotation of the winding bobbin in order to lift the thread off the groove of the groove roller, whereby the thread guide is moved in the thread running direction between the thread and the groove roller, so that only slight friction or reduced friction occurs between the thread guide and the thread compared to a stationary thread guide.

In principle, the method of the invention can be used as desired to prevent incorrect laying of the yarns. The groove for the yarn to be lifted off the grooved roller can be carried out by means of the yarn guide, if necessary, when a faulty laying occurs or periodically when the yarn is wound up in the edge region of the yarn bobbin. In order to detect a faulty laying and/or a required lifting of the thread, the winding of the thread and in particular the position of the thread on the thread bobbin or on the winding bobbin and/or the thread tension are monitored, wherein the method according to the preferred embodiment is particularly preferably used only when this is required, i.e. a faulty laying occurs. The monitoring can take place in any manner. Optical monitoring, in particular by means of a camera, is conceivable here, for example. It is also possible to monitor the yarn tension, in particular by means of a yarn tension sensor, since fluctuations, in particular sudden decreases, in the yarn tension occur during incorrect laying, in particular during the formation of a selvedge on the side of the yarn bobbin. The yarn speed monitoring can also be carried out because the groove roller forces the yarn to follow a known course predetermined by the shape of the groove when the yarn is guided correctly, so that the yarn speed profile is compared with the known profile and, if the deviation is sufficiently large, a faulty laying of the yarn can be inferred.

It is also preferred that the yarn can also be periodically lifted out of the groove of the grooved roller, particularly preferably when the yarn is located at the edge region of a yarn bobbin or a winding bobbin. For this purpose, the rotational speed of the grooved roller and/or the position of the yarn in the groove of the grooved roller can be monitored.

According to an advantageous development of the method according to the invention, the thread guide is moved far enough along the circumference of the groove roller when the thread is lifted off the groove of the groove roller, that is to say the thread is just lifted off the groove and in particular is just completely lifted off the groove, wherein it is particularly preferred to move the thread guide back at least immediately thereafter to the extent that the thread is guided again by the groove, as a result of which, on the one hand, incorrect laying is prevented, but, on the other hand, the winding according to the defined thread position is only briefly disturbed, since the position of the thread lifted off the groove cannot be completely determined.

Detailed Description

The winding device 1 for producing a yarn bobbin 2 as shown in fig. 1 is one of a plurality of identical stations which are arranged parallel to one another on a textile machine, for example an automatic winding machine, which produces a yarn bobbin 2. Each of the winding devices 1 is used to rewind a feed bobbin 13, which is produced by means of a spinning machine and has only a relatively small amount of thread material, into a large-package winding bobbin 4, typically a thread bobbin 2.

For this purpose, the winding device 1 has a yarn bobbin creel 3 which is mounted pivotably about a pivot axis 18 and on which a winding bobbin 4 for forming a yarn bobbin 2 can be mounted. The yarn creel 3 is mounted in such a way that the winding bobbin 4 can roll along the surface of the grooved roller 6 during the entire winding of the yarn 7, the winding bobbin 4 being driven by the grooved roller 6 by frictional engagement.

The grooved roller 6 and the winding bobbin 4 have parallel axes of rotation and rotate in opposite directions R1, R2. The pivot axis 18 of the yarn package sub-frame 3 extends parallel to both axes of rotation. The grooved roller 6 has a single groove 9 on the surface, which extends at an angle to the axis of rotation from one end of the grooved roller 6 to the other and back again and intersects itself a number of times on the surface of the grooved roller 6. The groove 9 is provided for receiving the thread 7 to be wound, wherein the thread 7 is deflected in the winding front in a region of the grooved roller 6 and thus determines the position of the groove 9, in which the thread 7 is wound on the surface of the winding bobbin 4.

The thread 7 exiting from the feed bobbin 13 is guided by means of a feed device 8 relative to the center of the grooved roller 6, the feed device 8 being formed in the form of a substantially closed thread channel 11. Along the thread path 11, a thread tensioner 12, a clearer 14 and a thread tension sensor 17 as well as a groove roller 6 are arranged on the thread run 5 from the feed bobbin 13 to the winding bobbin 4.

The upper end of the supply device 8 is formed as a thread suction device 15 and is connected for this purpose via a suction connection 16 to a vacuum cross member 20, which extends over all the textile machine stations, each of which has a winding device 1. In addition, a thread connecting unit 19 is arranged on the supply device 8 adjacent to the thread suction device 15, said thread connecting unit being used to connect the thread 7 already wound onto the thread bobbin 2 to the newly supplied thread 7 of the feed bobbin 13.

To produce the thread bobbin 2, the thread 7 to be wound is first fed from a feed bobbin 13 by means of a supply device 8 to the grooved roller 6, where the thread 7 runs in a groove 9 in the surface of the grooved roller 6 and is thus diverted along a part of the surface of the grooved roller 6 to a predetermined position on the winding bobbin 4 (see fig. 2). The upper end of the supply device 8 in the form of a yarn suction device 15 has yarn guides 10 which are arranged generally below the groove roller 6 and a rotating plate 21 which is arranged above the groove roller 6, the yarn guides 10 and the rotating plate 21 keeping the upper opening of the supply device 8 sufficiently small that successful suction of, for example, textile fibers can be achieved. The yarn guide 10 and the rotating plate 21 are configured as nozzle guards extending along the grooved roller surface 6.

If the thread 7 enters the edge region of the thread bobbin 2 during winding and in particular exceeds it and thus forms an undesired run-off, the thread guide 10 extends parallel to the surface of the grooved roller 6 in such a way that the thread 7 rises away from the groove 9 on the surface of the grooved roller 6 (see fig. 3). Since the ends of the thread tensioning and supply device 8 are arranged in the center of the grooved roller 6, the position of the incorrectly laid thread 7 forming the skiving is no longer determined by the groove 9, but is pulled toward the center of the grooved roller 6, as a result of which, in turn, skiving or other forms of incorrect laying can be eliminated.

Subsequently, the thread guide 10 is moved back into its normal position, in which there is no contact with the thread 7, so that the thread 7 extends again in the groove 9 of the grooved roller 6.
