Description

[0001] Traversing device and winding device for winding several synthetic threads with one traversing device

[0002] The present invention relates to a traversing device according to the preamble of patent claim 1, in particular a traversing device for traversing a plurality of synthetic threads on a winding device, having a plurality of traversing units, a traction means, and a traversing drive, wherein the winding device has a plurality of winding stations arranged in series, which are arranged next to one another along a winding spindle of the winding device, wherein a traversing unit, each with a drive wheel, is assigned to the winding stations, wherein the traversing units are coupled to the traversing drive via the drive wheels and the traction means for driving them. The invention further relates to a winding device for winding a plurality of synthetic threads having such a traversing device.

[0003] Using such a winding device, melt-spun yarns are wound parallel to bobbins. Conventional winding machines have a large number of winding stations, e.g., 16, 18, or 20 winding stations. This allows for high productivity, so that each yarn can be wound into a bobbin with particularly low energy consumption. To increase productivity and further reduce energy consumption, one development goal is to further increase the number of winding stations on a single winding device. The traversing device of the winding device must then have a correspondingly large number of traversing units.

[0004] Such a traversing device for a winding device is known from DE 10 2013 000 447 A1. The traversing device comprises four traversing units, each with a drive wheel. All drive wheels are driven by the same traction mechanism, designed as a toothed belt. The traction mechanism is driven by a single electric motor via a drive wheel coupled to the belt.

[0005] If the traversing system is to have 16, 18, 20, or even more traversing units, a correspondingly long timing belt is required to drive them. Such long timing belts are difficult to produce and exhibit less uniformity than a shorter timing belt, for example, for four traversing units. This reduced uniformity can lead to increased friction losses on the drive wheels and to undesirable fluctuations in the traversing speed of the traversing units.

[0006] Brief description of the invention

[0007] The present invention is based on the object of providing a traversing device and a winding apparatus for winding multiple synthetic threads with a traversing device that reduce or eliminate the problems of the prior art. In particular, the traction device should be simple to manufacture and highly uniform.

[0008] This object is firstly achieved by a traversing device according to claim 1.

[0009] Further advantageous embodiments are the subject of the subclaims.

[0010] More precisely, the object is achieved in that a predetermined first number of drive wheels is coupled to the oscillating drive by a first traction means and in that a predetermined second number of drive wheels is coupled to the oscillating drive by a second traction means.

[0011] The traction means are in particular designed as closed traction means, i.e. the respective traction means does not have two ends. The respective traction means is guided in a circle around the respective predetermined number of drive wheels. The coupling of a drive wheel with the associated traction means takes place by the traction means partially wrapping around the drive wheel, which is appropriately pretensioned to create the wrapping. By using the first and the second traction means, these two traction means can each be designed to be shorter than the single traction means according to the prior art, whereby the prerequisite is that the same number of traversing units can be driven. Two shorter traction means can be manufactured more easily and with greater uniformity than one long traction means. In particular, two standardized traction means can then be used instead of one specially manufactured traction means.By distributing the drive of the majority of the drive wheels between the two traction means, a more uniform traversing of the threads can be achieved on all traversing units of the traversing device, so that bobbins of higher quality can be produced.

[0012] Advantageously, the first traction means is coupled to at least two of the drive wheels to drive them. The second traction means is coupled to at least two other drive wheels of the drive wheels to drive them. The first traction means and the second traction means are coupled to the oscillating drive by means of a gear unit. The gear unit can be designed in different ways. The oscillating drive is preferably designed as a motor, particularly preferably as an electric motor.

[0013] In a preferred embodiment of the traversing device, the traversing units and the drive wheels are arranged in a row, with the two traction means each coupled to adjacent drive wheels. This allows the length of the two traction means to be further reduced, which further simplifies production and further increases the uniformity of the two traction means, with the aforementioned advantages.

[0014] Further preferably, the traversing drive is arranged between a first plane and a second plane, each of which runs perpendicular to the longitudinal direction of the row of drive wheels. The first plane runs through the drive wheel that can be driven by the first traction means and is arranged closest to the second traction means. The second plane runs through the drive wheel that can be driven by the second traction means and is arranged closest to the first traction means. In simple terms, the traversing drive is arranged centrally between the two traction means. The traversing drive is further preferably arranged on a side of the two traction means facing away from the threads to be traversed. The traversing drive is preferably at a substantially equal distance from the two traction means, so that both traction means can be driven in the same way by means of the traversing drive.Preferably, the traction means are designed as double-toothed toothed belts, which alternately wrap around the adjacent drive wheels. This alternate wrap achieves the necessary amount of wrap around the individual drive wheels to drive the drive wheels. Between the drive wheels of the traversing units, no additional wrap means are required due to the alternate wrap. Two adjacent drive wheels are in contact with opposite sides of the toothed belt. The drive wheels each have corresponding recesses into which the teeth of the toothed belt engage, thus achieving a high and reliable power transmission between the toothed belt and the drive wheels.

[0015] It can be advantageous if the gear unit has a first double wheel and a second double wheel, wherein the first double wheel is coupled in a first region to the first traction means for driving the latter, wherein the second double wheel is coupled in a first region to the second traction means for driving the latter. The traction means partially wrap around the double wheels in the first region. If the traction means are designed as toothed belts, the double wheels also have corresponding recesses in the first region into which the teeth of the toothed belts engage for power transmission. The two double wheels are preferably at the same distance from a longitudinal axis of the winding spindle.

[0016] Advantageously, the first area of ​​the first double wheel, the first area of ​​the second double wheel, and the two traction means are arranged in one plane. This is made possible in particular by the use of the two double wheels. If the two traction means are arranged in one plane, all threads can be traversed with essentially identical traversing units at the same distance from the winding spindle, resulting in a uniform package structure along the winding spindle. The arrangement of the traction means in one plane also leads to an essentially constant tension in the respective traction means, which has a positive effect on the durability of the traction means.

[0017] The gear unit further preferably has a motor drive wheel and a third traction means, in particular a single-toothed toothed belt. The motor drive wheel is connected in a rotationally fixed manner to a shaft of the oscillating drive. The third traction means is coupled to the motor drive wheel and can thus be driven by means of the oscillating drive. The first double wheel and the second double wheel are each coupled in a second region to the third traction means for driving them. The third traction means partially wraps around the double wheels in the second region and partially around the motor drive wheel. If the third traction means is designed as a toothed belt, the double wheels in the second region and the motor drive wheel each have corresponding recesses into which the teeth of the toothed belt engage for power transmission.The double wheels can be constructed as a single piece, or the first and second sections can each be formed by means of a disk that is non-rotatably connected to a double wheel shaft. Conventional shaft-hub connections are then used to create such a non-rotatable connection.

[0018] In a preferred, alternative embodiment of the traversing device, the gear unit has a drive gear arranged and / or formed on a shaft of the traversing drive. The drive gear engages with a gear arranged and / or formed on the first double wheel in a second region for driving the first double wheel. The drive gear also engages with a gear arranged and / or formed on the second double wheel in a second region for driving the second double wheel. With this design of the gear unit, the traversing drive can be arranged particularly close to the two double wheels, which has a positive overall effect on the space required for the entire traversing device.

[0019] In a further preferred embodiment of the traversing device, the gear unit has a motor drive wheel, a third traction means, in particular a single-toothed toothed belt, and a triple wheel. The motor drive wheel is then connected in a rotationally fixed manner to a shaft of the traversing drive. The third traction means is coupled to the motor drive wheel and can thus be driven by means of the traversing drive. The triple wheel is coupled in a first area to the first traction means for driving it. The triple wheel is coupled in a second area to the second traction means for driving it. The triple wheel is coupled in a third area to the third traction means for driving the triple wheel. Instead of the two double wheels, a single triple wheel is used here, which means that fewer components such as bearings are required. However, the two traction means can then no longer be arranged completely in one plane, since they are at different heights orare coupled to the triple wheel in an axially spaced area relative to the longitudinal axis of the triple wheel. The first traction means wraps around the triple wheel in the first area, the second traction means wraps around the triple wheel in the second area, and the third traction means partially wraps around the triple wheel in the third area. If the traction means are designed as toothed belts, the triple wheel in the first, second, and third areas and the motor drive wheel have corresponding recesses into which the teeth of the toothed belts engage to transmit power. Alternatively, it would also be conceivable here for the gear unit to have a drive gear arranged and / or formed on a shaft of the oscillating drive, the drive gear engaging with a gear arranged and / or formed on the triple wheel in a third area for driving the triple wheel.

[0020] Preferably, each of the traversing units is designed as a wing traversing unit with two counter-rotating wing rotors and a transfer gear. The coupling between the two wing rotors of each wing traversing unit and the associated drive wheel is achieved by means of the associated transfer gear. Using such wing traversing units, the threads can be guided back and forth particularly quickly. The direction of rotation of the two wings is not changed during operation; instead, the wings rotate at an essentially constant speed. During their traversing, the threads contact a guide bar of the traversing device. At both ends of a traversing stroke, each thread is lifted by means of the guide bar over one end of a thread-guiding wing of one of the wing rotors, before being taken over by a wing of the counter-rotating wing rotor. This transfer changes the direction of movement of the respective thread.

[0021] Further preferably, the traversing units with the associated drive wheels are divided into a first group and a second group, wherein each traction means is coupled to all drive wheels of one of the two groups to drive them. This ensures that no further traction means or other means are required to drive one of the traversing units of the traversing device. It can be advantageous if the first group and the second group have the same number of drive wheels or a different number of drive wheels. If the first group and the second group have the same number of drive wheels, the two traction means can in particular be of the same length. Identical traction means can then be used, which has a positive effect on their procurement.

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

[0023] The object of the invention is also achieved by a winding device for winding multiple synthetic threads with a traversing device as described above. This traversing device allows the number of threads that can be wound using the winding device to be further increased without compromising the quality of the traversing and thus the quality of the bobbins.

[0024] The winding devices are preferably used in melt spinning machines in which a molten polymer is spun into a plurality of filaments and combined into several threads, wherein the threads are subsequently drawn and then wound into spools by means of the winding device.

[0025] In the following, preferred embodiments are presented in more detail with reference to the attached figures.

[0030] Fig. 3b shows schematically a section of the third embodiment of the traversing device in a side view, partly in section.

[0031] Figures 1a to 3b show three different embodiments of a traversing device 1 for traversing a plurality of synthetic threads 2.1 - 2.6 on a winding device 3, all of which have a plurality of traversing units 4.1 - 4.6, at least one traction means 5.1, 5.2 and a traversing drive 6. Figures 1a, 2a and 3a show three different embodiments of a winding device 3 associated with the respective traversing device 1. The three different embodiments of the winding device 3 differ only in the traversing device 1 arranged on the respective winding device 3. Each of these winding devices 3 has a plurality of winding stations 7.1 - 7.6 arranged in series, which are arranged next to one another along a winding spindle 8 of the winding device 3. The winding stations 7.1 - 7.6 are each assigned a traversing unit 4.1 - 4.6 with a drive wheel 9.1 - 9.6, whereby the traversing units 4.1 - 4.6 are coupled to the oscillating drive 6 via the drive wheels 9.1 - 9.6 and the traction means 5.1, 5.2 for driving them. A predetermined first number of drive wheels 9.1 - 9.3 is coupled to the oscillating drive 6 via a first traction means 5.1, and a predetermined second number of drive wheels 9.4 - 9.6 is coupled to the oscillating drive 6 via a second traction means 5.2, as can be seen in particular from Figures 1a, 2a, and 3a. The first traction means 5.1 is coupled to at least two of the drive wheels 9.1 - 9.3 for driving them. The second traction means 5.2 is coupled to at least two further, other drive wheels 9.4 - 9.6 of the drive wheels for driving them. The first traction means.

[0032] 5.1 and the second traction means 5.2 are coupled to the traversing drive 6 by means of a gear unit 10. The three embodiments of the traversing device 1 differ essentially only in the design of this gear unit 10, so that all further explanations apply to all embodiments. According to Figures 1a, 2a and 3a, by way of example, in particular for the sake of clarity, only six traversing units 4.1 - 4.6 are provided in total. Of course, fewer, for example three, four or five, traversing units can also be used on a winding device 3. Typically, however, more than six traversing units are used on a winding device 3. The traversing device 1 has a total of, for example, 10 to 22, particularly preferably 14 to 22, traversing units. With such a high number of traversing units, the advantages of dividing their drive between two traction means 5.1, 5.2 have a correspondingly strong effect.Despite the use of these two traction devices 5.1, 5.2, only a single oscillating drive 6 is necessary.

[0033] The traversing units 4.1 - 4.6 and the drive wheels 9.1 - 9.6 are arranged in a row. The two traction devices 5.1, 5.2 are each coupled to adjacent drive wheels 9.1 - 9.3 and 9.4 - 9.6. Thus, all threads 2.1 - 2.6 are essentially in a plane parallel to the longitudinal direction L of the row of drive wheels.

[0034] 9.1 - 9.6 can be guided with the traversing units 4.1 - 4.6, so that all threads 2.1 - 2.6 are traversed transversely to this longitudinal direction L during operation of the winding device 3 at the same distance from the longitudinal axis of the winding spindle 8 with the traversing units 4.1 - 4.6. Due to the coupling of the two traction devices 5.1, 5.2 with adjacent drive wheels 9.1 - 9.3 and 9.4 - 9.6, simple guidance of the traction devices 5.1, 5.2 is possible, and furthermore, traction devices 5.1, 5.2 of minimal length can be used. The traction means 5.1, 5.2 each partially wrap around the drive wheels 9.1 - 9.6, so that a force- and / or frictional connection between the traction means 5.1, 5.2 and the drive wheels 9.1 - 9.6 enables the drive of the drive wheels 9.1 - 9.6 by means of the traction means 5.1, 5.2. For this purpose, the traction means 5.1, 5.2 are set in motion by the traversing drive 6 during operation of the traversing device 1 and guided past the drive wheels 9.1 - 9.6. The traction means 5.1, 5.22 are pre-tensioned to a respective operating tension during operation of the traversing device 1 by means of a tensioning device which has a tensioning roller partially wrapped around the respective traction means 5.1, 5.2, so that the traction means 5.1, 5.2 can be guided around the drive wheels 9.1 - 9.6 in a controlled manner, with the respective predetermined, required wrapping and a respective predetermined required pressing force acting between the respective traction means 5.1, 5.2 and the respective drive wheel 9.1 - 9.6.

[0035] The oscillating drive 6 is arranged between a first plane Ei and a second plane E2, each of which runs perpendicular to the longitudinal direction L of the row of drive wheels 9.1 - 9.6. The first plane Ei runs through the drive wheel 9.3, which is drivable by means of the first traction means 5.1 and is arranged closest to the second traction means 5.2. The second plane E2 runs through the drive wheel 9.4, which is drivable by means of the second traction means 5.2 and is arranged closest to the first traction means 5.1. The oscillating drive 6 is thus arranged in a central region of the oscillating device 1 with respect to the longitudinal direction L of the row of drive wheels 9.1 - 9.6.

[0036] The traction devices 5.1, 5.2 are designed as double-toothed toothed belts, which alternately wrap around the 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 devices 5.1, 5.2 can be driven in opposite directions. The alternate wrapping results in a sufficient wrap to drive the drive wheels 9.1 - 9.6. The traction devices 5.1, 5.2 themselves are coupled to the traversing drive 6 in such a way that they rotate in opposite directions during operation of the traversing device 1. The first traction means 5.1 wraps around the drive wheel 9.3 arranged closest to the second traction means 5.2 with contact to an inner side of the first traction means 5.1 and the second traction means 5.2 wraps around the drive wheel 9.4 arranged closest to the first traction means 5.1 with contact to an outer side of the second traction means 5.2.Thus, the drive wheel 9.3, which is wrapped around the first traction means 5.1 and arranged 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 wrapped closest to the first traction means 5.1 and the second traction means 5.2. To achieve the opposite direction of rotation, it would also be conceivable for the first traction means 5.1 to wrap around the drive wheel 9.3, which is arranged closest to the second traction means 5.2, with contact to an outer side of the first traction means 5.1, and for the second traction means 5.2 to wrap around the drive wheel 9.4, which is arranged closest to the first traction means 5.1, with contact to an inner side of the second traction means 5.2. The inner side of a traction means 5.1, 5.2 faces an interior space enclosed by the respective traction means 5.1, 5.2. The outer side of each traction means 5.1, 5.2 is arranged on a side facing away from the respective interior space.

[0037] According to the first and second embodiments of the traversing device 1 shown in Fig. 1a, 1b, 2a, and 2b, the gear unit 10 comprises a first double wheel 11.1 and a second double wheel 11.2. The first double wheel 11.1 is coupled in a first region 11.1.B1 to the first traction means 5.1 for driving the latter. The second double wheel 11.2 is coupled in a first region 11.2.B1 to the second traction means 5.2 for driving the latter. The first double wheel 11.1 and the second double wheel 11.2 are each mounted on a frame of the traversing device 1 so as to be rotatable about their longitudinal axes.

[0038] The first area 11.1.B1 of the first double wheel 11.1, the first area 11.2.B1 of the second double wheel 11.2, and the two traction means 5.1, 5.2 are arranged in one plane, as shown particularly in Figs. 1b and 2b. This results in essentially equal distances between the first area 11.1.B1 of the first double wheel 11.1, the first area 11.2.B1 of the second double wheel 11.2, and the two traction means 5.1, 5.2 from a longitudinal axis of the winding spindle 8.

[0039] According to the first embodiment of the traversing device 1 shown in Figs. 1a and 1b, the gear unit 10 further comprises a motor drive wheel 12 and a third traction means 5.3, in particular a single-toothed toothed belt. The motor drive wheel 12 is rotationally fixedly connected to a shaft 13 of the traversing drive 6. The third traction means 5.3 is coupled to the motor drive wheel 12 and can thus be driven by the traversing drive 6. The first double wheel 11.1 and the second double wheel 11.2 are each coupled in a second area 11.1.B2, 11.2.B2 to the third traction means 5.3 for their drive. The respective first area 11.1.B1, 11.2.B1 and the respective second area 11.1,B2, 11.2.B2 are formed either on the respective double wheel 11.1, 11.2 or on a disc that is non-rotatably connected to the respective double wheel 11.1, 11.2. The respective first area 11.1.B1, 11.2.B1 and the respective second area 11.1,B2, 11.2.B2 are designed to enable a force-locking and / or form-locking connection between the respective double wheel 11.1, 11.2 and the respective traction means 5.1, 5.2, 5.3. The creation of the force-locking and / or form-locking connection is also made possible, in particular, by pre-tensioning 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 the areas 11.1.B1, 11.2.B1, 11.2.B2, and 11.2.B2, into which the teeth of the toothed belts engage.

[0040] According to the second embodiment of the traversing device 1 shown in Figs. 2a and 2b, the gear unit 10 has a drive gear 14 arranged and / or formed on a shaft 13 of the traversing drive 6. The drive gear 14 engages with a gear 11.1.Z arranged and / or formed on the first double wheel 11.1 in a second region 11.1,B2 for driving the first double wheel 11.1. The drive gear 14 also engages with a gear 11.2.Z arranged and / or formed on the second double wheel 11.2 in a second region 11.2.B2 for driving the second double wheel 11.2. The two double wheels 11.1, 11.2 can be driven in the same direction of rotation by means of the gear unit 10 according to both the first and the second embodiment of the traversing device 1. The two traction devices 5.1, 5.2 wrap around the respective first area 11.1.B1, 11.2.B1 on mutually facing sides with respect to the respective longitudinal axis of the double wheels 11.1, 11.2, so that the two traction means 5.1, 5.2 rotate in opposite directions during operation of the traversing device 1.

[0041] According to the third embodiment of the traversing device 1 from Figs. 3a and 3b, the gear unit 10 has a motor drive wheel 12, a third traction means 5.3, in particular a single-toothed toothed belt, and a triple wheel 15. The motor drive wheel 12 is rotationally fixedly connected to a shaft 13 of the traversing drive 6. The third traction means 5.3 is coupled to the motor drive wheel 12 and can thus be driven by the traversing drive 6. The triple wheel 15 is coupled in a first region 15.B1 to the first traction means 5.1 for driving it. The triple wheel 15 is coupled in a second region 15.B2 to the second traction means 5.2 for driving it. The triple wheel 15 is coupled in a third region 15.B3 to the third traction means 5.3 for driving the triple wheel 15. The first, second and third regions 15.B1, 15.B2 and 15.B3 are formed either on the triple wheel 15 or on a disc each connected in a rotationally fixed manner to a shaft of the triple wheel 15.The first, second, and third regions 15.B1, 15.B2, and 15.B3 are designed to enable a force-locking and / or positive-locking connection between the triple wheel 15 and the respective traction means 5.1, 5.2, 5.3. The creation of the force-locking and / or positive-locking connection is also made possible, in particular, by the pretensioning 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 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 at least partially each arranged in a plane which has different distances from the longitudinal axis of the winding spindle 8.

[0042] Each of the traversing units 4.1 - 4.6 is designed as a vane traversing unit with two counter-rotating vane rotors 16 and a distribution gear 17. The coupling between the two vane rotors 16 of each vane traversing unit and the associated drive wheel 9.1 - 9.6 is achieved by means of the associated distribution gear 17. During their traversing, the threads 2.1 - 2.6 contact a guide rail 18 of the traversing device 1, which enables the traversing by means of the two counter-rotating vane rotors 16. In contrast, it would theoretically also be conceivable to design the traversing units 4.1 - 4.6 using reverse-threaded shafts or belt traversing mechanisms.

[0043] The traversing units 4.1 - 4.6 with the associated drive wheels 9.1 - 9.6 are divided into a first group and a second group, whereby each traction device 5.1 is coupled to all drive wheels 9.1 - 9.3 and 9.4 - 9.6 of one of the two groups to drive them.

[0044] 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. However, it would also be conceivable for the first group and the second group to have different numbers of drive wheels. The winding device 3 serves to wind up a plurality of synthetic threads 2.1 - 2.6 and has the traversing device 1 described above, wherein the winding device 3 is preferably part of a melt spinning machine in which a molten polymer is spun into a plurality of filaments and combined to form the plurality of threads 2.1 - 2.6, wherein the threads 2.1 - 2.6 are subsequently stretched and then wound up into bobbins 19.1 - 19.6 by means of the winding device 3, wherein the threads 2.1 - 2.6 are traversed during the winding up to form the bobbins 19.1 - 19.6 by means of a respective traversing unit 4.1 - 4.6 of the traversing device 1.During winding, a pressure roller 20 of the winding device 3 rests on the surface of the spools 19.1 - 19.6.
