Description

Technical Field

[0001] The present invention relates to a traversing device as described in the preamble of claim 1, comprising a plurality of traversing units, a traction means and a traversing drive device, particularly to a traversing device for traversing a plurality of synthetic yarns in a winding device. The winding device comprises a plurality of serially arranged winding locations arranged side by side along the winding spindle of the winding device. Each winding location is assigned one traversing unit having one drive wheel each. The traversing unit is connected to the traversing drive device via the drive wheel and the traction means for driving the traversing unit. The present invention further relates to a winding device for winding a plurality of synthetic yarns, comprising such a traversing device.

Background Art

[0002] With such a winding device, preferably, the melt-spun yarn is wound parallel to the spool. A general winding machine has a plurality of winding locations, for example 16, 18 or 20 winding locations. In this way, high productivity can be achieved, and thereby each yarn can be wound onto the spool with particularly low energy consumption. One of the development goals is to further increase the number of winding locations in a single winding device in order to improve productivity and further reduce energy consumption. In that case, the traversing device of the winding device needs to have a corresponding number of traversing units.

[0003] The traversing device of such a winding device is known from German Patent Application Publication No. 102013000447. The traversing device here comprises four traversing units each having one drive wheel. All drive wheels are driven by the same traction means designed as a toothed belt. The drive of the traction means is effected by a single drive device designed as an electric motor via the drive wheels connected to the belt.

[0004] If a traverse device needs to have 16, 18, 20, or even more traverse units, a correspondingly long toothed belt is required to drive them. Such long toothed belts are difficult to manufacture and have lower uniformity compared to, for example, a relatively short toothed belt for four traverse units. This relatively low uniformity increases friction loss on the drive wheels and can lead to undesirable fluctuations in the traverse speed of the traverse units. [Overview of the project] [Problems that the invention aims to solve]

[0005] The present invention is based on the objective of providing a traverse device that mitigates or eliminates the problems of the prior art, and a winding device for winding up multiple synthetic yarns equipped with the traverse device. In particular, the traction means must be easy to manufacture and highly uniform. [Means for solving the problem]

[0006] This problem is solved, firstly, by the traverse device described in claim 1.

[0007] Other advantageous embodiments are the subject of the dependent claims.

[0008] More precisely, this problem is solved by having a predetermined first number of drive wheels connected to the traverse drive system by a first traction means, and a predetermined second number of drive wheels connected to the traverse drive system by a second traction means.

[0009] The traction means are specifically designed as closed traction means, meaning that each traction means does not have two ends. Each traction means is guided in a loop around each predetermined number of drive wheels. The connection between the drive wheels and the associated traction means is achieved by the partial wrapping of the drive wheels by the traction means, and a corresponding pretension is applied to the traction means to generate the wrapping. By using first and second traction means, these two traction means can each be designed to be shorter than a single traction means in the prior art, provided that the same number of traverse units in total can be driven. Two shorter traction means can be manufactured more easily and with greater uniformity than a longer traction means. In particular, in this case, two standardized traction means can be used instead of specially manufactured traction means. Thus, by distributing the driving of most of the drive wheels to two traction means, more uniform thread traverse can be achieved in all traverse units of the traverse device, thereby enabling the creation of spools of higher quality.

[0010] Advantageously, the first traction means is coupled to at least two of the drive wheels for driving at least two of the drive wheels. The second traction means is coupled to at least two yet another of the drive wheels for driving at least two yet another drive wheels. The first and second traction means are coupled to a traverse drive by a gear unit. In this case, the gear unit can be designed in various ways. The traverse drive is preferably designed as a motor, and particularly preferably as an electric motor.

[0011] In a preferred embodiment of the traverse device, the traverse unit and the drive wheels are arranged in a line, and two traction means are each connected to adjacent drive wheels. Thus, the lengths of the two traction means can be further reduced, thereby further simplifying manufacturing, further improving the uniformity of the two traction means, and obtaining the advantages already mentioned.

[0012] More preferably, the traverse drive is positioned between a first plane and a second plane, each extending perpendicular to the longitudinal direction of the row of drive wheels. The first plane extends through the drive wheel closest to the second traction means, which is driveable by the first traction means. The second plane extends through the drive wheel closest to the first traction means, which is driveable by the second traction means. In short, the traverse drive is positioned in the middle between the two traction means. More preferably, the traverse drive is positioned on the side of the two traction means away from the thread being traversed. The traverse drive is preferably at substantially the same distance from the two traction means, so that both traction means can be driven in the same way by the traverse drive.

[0013] Preferably, the traction means is designed as a double-toothed toothed belt that wraps alternately around adjacent drive wheels. By wrapping alternately, each drive wheel receives a wrap of the size necessary to drive the drive wheel. By wrapping alternately, there is no need for another wrap between the drive wheels of the traverse unit. In this case, two adjacent drive wheels are in contact with the opposing sides of the toothed belt. Each drive wheel has a corresponding recess into which the teeth of the toothed belt engage, thereby achieving high and reliable power transmission between the toothed belt and the drive wheels.

[0014] It may be advantageous if the gear unit has a first double wheel and a second double wheel, where the first double wheel is connected to a first traction means in a first region for driving the first double wheel, and the second double wheel is connected to a second traction means in a first region for driving the second double wheel. In this case, the traction means partially wrap around each double wheel in a first region. If the traction means is designed as a toothed belt, each double wheel also has corresponding recesses in a first region, where the teeth of the toothed belt engage for power transmission. The two double wheels are preferably at the same distance from the longitudinal axis of the winding spindle.

[0015] Advantageously, the first region of the first double wheel and the first region of the second double wheel, and the two traction means, are located in a single plane. This is also made possible by the use of two double wheels in particular. When the two traction means are located in a single plane, all the line can be traversed at the same distance relative to the winding spindle by traverse units of substantially the same structure, which results in similar spool formation along the winding spindle. Furthermore, by arranging the traction means in a single plane, the tension of each traction means becomes substantially constant, which has a positive effect on the durability of the traction means.

[0016] More preferably, the gear unit has a motor-driven wheel and a third traction means, in particular a single-tooth toothed belt. The motor-driven wheel is non-rotatably connected to the shaft of the traverse drive. The third traction means is coupled to the motor-driven wheel and is thereby drivable by the traverse drive. The first double wheel and the second double wheel are each coupled to the third traction means in a second region for driving the first and second double wheels. In this case, the third traction means wraps partially around the double wheel and partially around the motor-driven wheel in the second region. If the third traction means is designed as a toothed belt, the double wheel each has a second region and the motor-driven wheel has a corresponding recess, in which the teeth of the toothed belt engage for power transmission. The double wheel can be designed as a single unit, or the first and second regions are each formed using a disc non-rotatably connected to the double wheel shaft. In this case, a common shaft hub connection is used to create such a non-rotatable connection.

[0017] In a preferred alternative embodiment of the traverse device, the gear unit has a drive gear located and / or formed on the shaft of the traverse drive unit. The drive gear meshes with a gear located and / or formed in a second area of ​​the first double wheel for driving the first double wheel. The drive gear also meshes with a gear located and / or formed in a second area of ​​the second double wheel for driving the second double wheel. In this embodiment of the gear unit, the traverse drive unit can be located particularly close to the two double wheels, which has a positive impact on the overall required space of the traverse device.

[0018] In a more preferred embodiment of the traverse device, the gear unit includes a motor-driven wheel, a third traction means, particularly a single-toothed toothed belt, and a triple wheel. In this case, the motor-driven wheel is non-rotatably connected to the shaft of the traverse drive device. The third traction means is coupled to the motor-driven wheel and is thereby driveable by the traverse drive device. The triple wheel is coupled to the first traction means in a first region for its drive. The triple wheel is coupled to the second traction means in a second region for its drive. The triple wheel is coupled to the third traction means in a third region for its drive. Thus, here, one triple wheel is used instead of two double wheels, thereby reducing the number of necessary components such as bearings. However, in this case, the two traction means are connected to the triple wheel at different heights or in axially spaced regions relative to the longitudinal axis of the triple wheel, so it becomes impossible to place the two traction means completely in a single plane. The first traction means partially wraps around the triple wheel in the first region, the second traction means partially wraps around the triple wheel in the second region, and the third traction means partially wraps around the triple wheel in the third region. If the traction means is designed as a toothed belt, the triple wheel has corresponding recesses in the first, second, and third regions, and the motor drive wheel has corresponding recesses, in which the teeth of the toothed belt engage for power transmission. Alternatively, a gear unit may also be considered here having a drive gear located and / or formed on the shaft of the traverse drive unit, the drive gear meshing with a gear located and / or formed in the third region of the triple wheel for driving the triple wheel.

[0019] Preferably, each traverse unit is designed as a feather traverse unit (Fluegelchangiereinheit) having two counter-rotating feather rotors (Fluegelrotor) and a distribution gear (Verteilergetriebe). The coupling between the two feather rotors of each feather traverse unit, which has associated drive wheels, is done by associated distribution gears. Such feather traverse units allow the thread to reciprocate particularly quickly. The rotational direction of the two feathers does not change during these movements, and the feathers rotate at a substantially constant speed. The thread comes into contact with a guide ruler of the traverse device during its traverse. At both ends of the traverse stroke, each thread is lifted by the guide ruler (Leitlineal) over one end of the thread guide feather of one of the feather rotors, and then received by the feathers of the counter-rotating feather rotor. This transfer changes the direction of motion of each thread.

[0020] More preferably, the traverse units having associated drive wheels are divided into a first group and a second group, and each traction means is coupled to all the drive wheels of one of the two groups for driving them. This ensures that there is no need for another traction means or other means to drive one of the traverse units of the traverse device.

[0021] It may be advantageous for the first and second groups to have the same number of drive wheels or different numbers of drive wheels. If the first and second groups have the same number of drive wheels, the two towing means can be designed to be of the same length. In that case, towing means of the same structure can be used, which has a positive impact on their procurement.

[0022] The traverse device has a total of preferably 4 to 22, preferably 10 to 22, and particularly preferably 14 to 22 traverse units.

[0023] The object of the present invention is also solved by a winding device for winding a plurality of synthetic yarns provided with the traversing device described above. With this traversing device, the number of yarns that can be wound by the winding device can be further increased without impairing the traversing and thus the quality of the spool.

[0024] The winding device is preferably used in a melt spinning machine, in which the molten polymer is spun into a number of filaments, gathered into several yarns, and subsequently the yarns are drawn and then wound onto a spool by the winding device.

[0025] Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings.

Modes for Carrying Out the Invention

[0027] Figures 1a to 3b show three different embodiments of a traverse device 1 for traversing multiple synthetic yarns 2.1 to 2.6 in a winding device 3, all of which include multiple traverse units 4.1 to 4.6, at least one traction means 5.1, 5.2, and a traverse drive device 6. Figures 1a, 2a, and 3a show three different embodiments of a winding device 3 belonging to each traverse device 1. The three different embodiments of the winding device 3 differ only in the traverse device 1 arranged in each winding device 3. Each of these winding devices 3 has multiple winding sections 7.1 to 7.6 arranged in series along the winding spindle 8 of the winding device 3. Each winding section 7.1 to 7.6 is assigned one traverse unit 4.1 to 4.6, each having one drive wheel 9.1 to 9.6. The traverse units 4.1 to 4.6 are connected to the traverse drive unit 6 via the drive wheels 9.1 to 9.6 and traction means 5.1 and 5.2 for driving. In particular, as can be seen from Figures 1a, 2a, and 3a, a predetermined first number of drive wheels 9.1 to 9.3 are connected to the traverse drive unit 6 by the first traction means 5.1, and a predetermined second number of drive wheels 9.4 to 9.6 are connected to the traverse drive unit 6 by the second traction means 5.2.

[0028] The first traction means 5.1 is connected to at least two of the drive wheels 9.1-9.3 for driving them. The second traction means 5.2 is connected to at least two further drive wheels 9.4-9.6 for driving them. The first traction means 5.1 and the second traction means 5.2 are connected to the traverse drive unit 6 via a gear unit 10. Since the three embodiments of the traverse device 1 differ substantially only in the embodiment of this gear unit 10, all other embodiments apply to all exemplary embodiments. As shown in Figures 1a, 2a, and 3a, only a total of six traverse units 4.1-4.6 are provided, exemplary and especially for clarity. Naturally, fewer traverse units, for example three, four, or five, can also be used in the winding device 3. However, typically more than six traverse units are used in the winding device 3. The traverse device 1 has a total of, for example, 10 to 22, and particularly preferably 14 to 22, traverse units. When there are so many traverse units, the advantage of distributing their drive to two traction means 5.1 and 5.2 becomes considerably stronger. Despite using these two traction means 5.1 and 5.2, only one traverse drive device 6 is required.

[0029] The traverse units 4.1-4.6 and the drive wheels 9.1-9.6 are arranged in a row. Both traction means 5.1 and 5.2 are connected to the adjacent drive wheels 9.1-9.3 and 9.4-9.6, respectively. Thus, all threads 2.1-2.6 can be guided by the traverse units 4.1-4.6 in substantially one plane parallel to the longitudinal direction L of the row of drive wheels 9.1-9.6, thereby, when the winding device 3 is in operation, all threads 2.1-2.6 are traversed by the traverse units 4.1-4.6 in the lateral direction L with respect to the longitudinal axis of the winding spindle 8 at the same distance. Since the two towing means 5.1 and 5.2 are connected to adjacent drive wheels 9.1-9.3 and 9.4-9.6 respectively, simple guidance of the towing means 5.1 and 5.2 is possible, and furthermore, the towing means 5.1 and 5.2 can be used with minimal length. Because the towing means 5.1 and 5.2 partially wrap around the drive wheels 9.1-9.6 respectively, the force-coupled and / or friction-coupled connection between the towing means 5.1 and 5.2 and the drive wheels 9.1-9.6 enables the towing means 5.1 and 5.2 to drive the drive wheels 9.1-9.6. When the traverse device 1 is in operation, the towing means 5.1 and 5.2 are moved by the traverse drive device 6 and guided past the drive wheels 9.1-9.6. The traction means 5.1 and 5.2 are pre-tensioned to their respective operating tensions by a tension device having a tension roller around which each traction means 5.1 and 5.2 partially wraps when the traverse device 1 is in operation. As a result, the traction means 5.1 and 5.2 can be controlled to guide around the drive wheels 9.1 to 9.6 with their respective predetermined required wraps and predetermined required pressing forces acting between each traction means 5.1 and 5.2 and their respective drive wheels 9.1 to 9.6.

[0030] The traverse drive unit 6 is positioned between a first plane E1 and a second plane E2, which extend perpendicularly to the longitudinal direction L of the rows of drive wheels 9.1 to 9.6, respectively. The first plane E1 extends through drive wheel 9.3, which is driveable by the first traction means 5.1 and is located closest to the second traction means 5.2. The second plane E2 extends through drive wheel 9.4, which is driveable by the second traction means 5.2 and is located closest to the first traction means 5.1. Therefore, the traverse drive unit 6 is positioned in the middle region of the traverse unit 1 with respect to the longitudinal direction L of the rows of drive wheels 9.1 to 9.6.

[0031] The traction means 5.1 and 5.2 are designed as double-toothed toothed belts that alternately wrap around adjacent drive wheels 9.1-9.3 and 9.4-9.6. Thus, adjacent drive wheels 9.1-9.6 driven by one of the traction means 5.1 or 5.2 can be driven in opposite rotational directions. The alternate wrapping provides a wrap of sufficient size for driving the drive wheels 9.1-9.6. The traction means 5.1 and 5.2 themselves are connected to the traverse drive unit 6 so as to circulate in opposite directions from each other when the traverse unit 1 is in operation. The first traction means 5.1 wraps around the drive wheel 9.3 closest to the second traction means 5.2 while in contact with the inside of the first traction means 5.1, and the second traction means 5.2 wraps around the drive wheel 9.4 closest to the first traction means 5.1 while in contact with the outside of the second traction means 5.2. Therefore, the drive wheel 9.3, which is wrapped around by the first traction means 5.1 and positioned closest to the second traction means 5.2, can be driven in the opposite direction of rotation to the drive wheel 9.4, which is closest to the first traction means 5.1 and wrapped around by the second traction means 5.2. To achieve the opposite direction of rotation, the first traction means 5.1 may wrap around the drive wheel 9.3, which is positioned closest to the second traction means 5.2, while contacting the outside of the first traction means 5.1, and the second traction means 5.2 may wrap around the drive wheel 9.4, which is positioned closest to the first traction means 5.1, while contacting the inside of the second traction means 5.2. In this case, the insides of the traction means 5.1 and 5.2 face the internal space enclosed by each traction means 5.1 and 5.2. The outsides of each traction means 5.1 and 5.2 are positioned away from this respective internal space.

[0032] According to the first and second embodiments of the traverse device 1 shown in Figures 1a, 1b, 2a, and 2b, the gear unit 10 has a first double wheel 11.1 and a second double wheel 11.2. The first double wheel 11.1 is connected to a first traction means 5.1 in a first region 11.1.B1 for its drive. The second double wheel 11.2 is connected to a second traction means 5.2 in a first region 11.2.B1 for its drive. The first double wheel 11.1 and the second double wheel 11.2 are each supported on the frame of the traverse device 1 so as to be rotatable about their longitudinal axes.

[0033] The first region 11.1.B1 of the first double wheel 11.1, the first region 11.2.B1 of the second double wheel 11.2, and the two traction means 5.1, 5.2 are arranged in a single plane, particularly as shown in Figures 1b and 2b. Thus, the distances of the first region 11.1.B1 of the first double wheel 11.1, the first region 11.2.B1 of the second double wheel 11.2, and the two traction means 5.1, 5.2 with respect to the longitudinal axis of the winding spindle 8 are substantially equal.

[0034] According to the first embodiment of the traverse device 1 shown in Figures 1a and 1b, the gear unit 10 further comprises a motor-driven wheel 12 and a third traction means 5.3, in particular a single-toothed toothed belt. The motor-driven wheel 12 is non-rotatably connected to the shaft 13 of the traverse drive device 6. The third traction means 5.3 is coupled to the motor-driven wheel 12 and is thereby drivable by the traverse drive device 6. The first double wheel 11.1 and the second double wheel 11.2 are coupled to the third traction means 5.3 in the second regions 11.1.B2 and 11.2.B2, respectively, for their driving. The first regions 11.1.B1 and 11.2.B1, respectively, and the second regions 11.1.B2 and 11.2.B2, respectively, are formed on the respective double wheels 11.1 and 11.2, or on each single disk non-rotatably connected to the respective double wheels 11.1 and 11.2. The first regions 11.1.B1, 11.2.B1, and the second regions 11.1.B2, 11.2.B2, respectively, are formed to enable force-coupled and / or shape-coupled connections between the respective double wheels 11.1, 11.2 and the respective traction means 5.1, 5.2, 5.3. The creation of force-coupled and / or shape-coupled connections is made possible, in particular, by the pre-tension of the traction means 5.1, 5.2, 5.3. If the traction means 5.1, 5.2, 5.3 are designed as toothed belts, corresponding recesses are formed in regions 11.1.B1, 11.2.B1, 11.1.B2, and 11.2.B2, into which the teeth of the toothed belt engage.

[0035] According to the second embodiment of the traverse device 1 shown in Figures 2a and 2b, the gear unit 10 has a drive gear 14 located and / or formed on the shaft 13 of the traverse drive device 6. The drive gear 14 meshes with a gear 11.1.Z located and / or formed in the second region 11.1.B2 of the first double wheel 11.1 for driving the first double wheel 11.1. The drive gear 14 meshes with a gear 11.2.Z located and / or formed in the second region 11.2.B2 of the second double wheel 11.2 for driving the second double wheel 11.2. The gear unit 10 according to both the first and second embodiments of the traverse device 1 can drive the two double wheels 11.1 and 11.2 in the same direction of rotation. The two traction means 5.1 and 5.2 wrap around the respective longitudinal axes of the double wheels 11.1 and 11.2, with their sides facing each other, in the respective first regions 11.1.B1 and 11.2.B1, so that the two traction means 5.1 and 5.2 rotate in opposite directions to each other when the traverse device 1 is in operation.

[0036] According to a third embodiment of the traverse device 1 shown in Figures 3a and 3b, the gear unit 10 includes a motor-driven wheel 12, a third traction means 5.3, in particular a single-toothed toothed belt, and a triple wheel 15. The motor-driven wheel 12 is non-rotatably connected to the shaft 13 of the traverse drive device 6. The third traction means 5.3 is coupled to the motor-driven wheel 12 and is therefore drivable by the traverse drive device 6. The triple wheel 15 is coupled to the first traction means 5.1 in the first region 15.B1 for its driving. The triple wheel 15 is coupled to the second traction means 5.2 in the second region 15.B2 for its driving. The triple wheel 15 is coupled to the third traction means 5.3 in the third region 15.B3 for its driving. The first, second, and third regions 15.B1, 15.B2, and 15.B3 are formed on the triple wheel 15 or on each individual disc that is non-rotatably connected to the shaft of the triple wheel 15. The first, second, and third regions 15.B1, 15.B2, and 15.B3 are formed to enable force-coupled and / or shape-coupled connections between the triple wheel 15 and the respective traction means 5.1, 5.2, and 5.3. The creation of force-coupled and / or shape-coupled connections is also made possible, in particular, by the pre-tension of the traction means 5.1, 5.2, and 5.3. If the traction means 5.1, 5.2, and 5.3 are designed as toothed belts, corresponding recesses are formed in regions 15.B1, 15.B2, and 15.B3, into which the teeth of the toothed belts engage. The first region 15.B1 and the first traction means 5.1, the second region 15.B2 and the second traction means 5.2, and the third region 15.B3 and the third traction means 5.3 are each at least partially located in a plane having different distances from the longitudinal axis of the winding spindle 8.

[0037] Each of the traverse units 4.1 to 4.6 is designed as a blade traverse unit having two counter-rotatable blade rotors 16 and a distribution gear 17. The coupling between the two blade rotors 16 of each blade traverse unit, which has associated drive wheels 9.1 to 9.6, is performed by the associated distribution gear 17. During its traverse, the threads 2.1 to 2.6 come into contact with a guide ruler 18 of the traverse device 1, which enables traverse by the two counter-rotatable blade rotors 16. In contrast, theoretically, the traverse units 4.1 to 4.6 could also be implemented using a reverse-threaded shaft (Kehrgewindewellen) or a belt-type traverse (Riemenchangierung).

[0038] Traverse units 4.1-4.6, each having associated drive wheels 9.1-9.6, are divided into a first group and a second group, with each traction means 5.1 coupled to all drive wheels 9.1-9.3 and 9.4-9.6 of one of the two groups for their drive.

[0039] According to the three exemplary embodiments, the first group and the second group each have the same number of drive wheels 9.1-9.3 and 9.4-9.6, respectively. Alternatively, the first group and the second group may have different numbers of drive wheels.

[0040] The winding device 3 is used to wind up a plurality of synthetic yarns 2.1 to 2.6 and has the aforementioned traverse device 1, and the winding device 3 is preferably part of a melt spinning machine, in which a molten polymer is spun into a number of filaments and gathered into several yarns 2.1 to 2.6, which are then stretched and subsequently wound onto spools 19.1 to 19.6 by the winding device 3, and the yarns 2.1 to 2.6 are traversed by each of the traverse units 4.1 to 4.6 of the traverse device 1 to form the spools 19.1 to 19.6 during winding. During winding, the press roller 20 of the winding device 3 rests on the surface of the spools 19.1 to 19.6. [Explanation of Symbols]
