Description

[0001] The present invention relates to a device for false-twisting synthetic yarns. The present invention also relates to a disc device for false-twisting synthetic yarns, and a modular system for a false-twisting device for synthetic yarns. Finally, the present invention also relates to a synthetic yarn texturing device.

[0002] A method for crimping a yarn, which is respectively referred to as so-called false-twisting or false-twist texturing, is used for post-finishing spun synthetic yarns. For this purpose, partially oriented yarns from a melt spinning process, such as so-called POY (pre-oriented yarns), can be crimped in a texturing device. In this process, a false twist propagating in a direction opposite to the running direction of the yarn is mechanically generated on the yarn. In this twisted state, the yarn is heated to a temperature in the range of 200 °C. The resulting plastic state of the yarn material causes the twist to be incorporated into the individual filaments of the yarn or into the yarn respectively. In order to shape this yarn structure, the yarn can subsequently be cooled to a lower temperature, for example to a temperature of about 80 °C. As a result, the crimps generated in the yarn are retained and have the desired post-finishing effect.

[0003] In order to mechanically generate a false twist, the texturing device can be equipped with a plurality of friction discs, which are arranged on a total of three drive shafts connected by belts. Thus, these friction discs run at the same rotational speed.

[0004] However, the individual friction discs of such a friction device can cause different torque inputs to the yarn to be post-finished, especially depending on the position of the respective friction disc within the friction device. This can lead to different degrees of wear on the friction discs. In addition, the process parameters for stabilizing the yarn running are limited by the disc with the highest torque input. Unstable yarn running, especially so-called fluctuations, usually occur on the friction disc with the highest torque input, thereby establishing a process limit in terms of higher operating speeds.

[0005] In view of the background outlined above, the object of the present invention is to provide a device for false-twisting synthetic yarns, which ensures increased productivity or respectively runs with improved process parameters. This object also aims to provide a disc device for false-twisting synthetic yarns, and a modular system for a device for false-twisting synthetic yarns. Finally, the object of the present invention is also to provide a synthetic yarn texturing device.

[0006] In respect of this device, this object is respectively achieved by the subject matter of claim 1 or the subject matter of claim 14. The disc device of the present invention is set forth in claim 15, and the modular system of the present invention is set forth in claim 16. Finally, a synthetic yarn texturing device is set forth in claim 17. Advantageous design embodiments are the subject matter of the dependent claims and will be explained below.

[0007] According to a first aspect of the present invention, an apparatus according to the present invention for false-twisting synthetic yarns is equipped with: a plurality of disks for contacting the synthetic yarn, at least one shaft receiving portion for driving a shaft, and a plurality of gear units, each of which is designed to transmit motion between at least one disk and a drive shaft that can be arranged in the shaft receiving portion.

[0008] Due to the provision of a plurality of gear units, different rotational speeds of the disks of the apparatus can be achieved in a particularly advantageous manner and with only little complexity. Thus, during operation of the apparatus according to the present invention, at least two disks can be driven at mutually different rotational speeds. For example, at least one disk for contacting the synthetic yarn can run faster or slower than another disk of the apparatus. In this way, the rotational speeds of the plurality of disks can be selected or set in a particularly advantageous manner for the corresponding desired process parameters or in order to increase the process limits. In particular, the torque input of the disks can be selected or set in a particularly advantageous manner thereby. Thereby, the productivity of the apparatus can be significantly increased.

[0009] According to an advantageous design embodiment, in each case, at least some of the disks can be assigned a separate gear unit. Particularly advantageously, each disk can be assigned a separate or dedicated gear unit. As a result, separate operating speeds can be set or selected for the corresponding disks or all disks of the apparatus. In this way, particularly advantageous and precisely set process parameters can be ensured, and overall high productivity can be achieved.

[0010] Additionally or alternatively, all the gear units can be arranged to transmit motion from a single drive shaft. As a result, the disks of the apparatus can be driven respectively by a single drive shaft or by a single drive motor. This can be ensured with little structural complexity while having high operating reliability. Furthermore, in terms of open-loop or closed-loop control, operating a single drive shaft and a single drive motor can be achieved with little complexity.

[0011] Furthermore preferably, the drive shaft, in particular the drive shaft connected to the drive motor, can be arranged in the shaft receiving portion. In particular, exactly one drive shaft, or the single drive shaft of the apparatus, can be arranged in the shaft receiving portion. This arrangement of the drive shaft in the shaft receiving portion enables reliable operation and reliable connection with the corresponding gear units, so that overall high operating reliability can be achieved.

[0012] According to a more advantageous design embodiment, at least one gear unit may have a gear ratio different from one of the other gear units. As a result, when using a single drive shaft, at least two disks can run at different rotational speeds from each other with little complexity. Similarly, multiple gear units may have the same gear ratio. Thus, multiple disks can also run at the same rotational speed. Generally speaking, in this way, the rotational speeds of the disks can be set or selected particularly advantageously for the desired process parameters.

[0013] According to a more advantageous design embodiment, at least one disk is rotatably mounted on a disk shaft that is separately positioned and / or spaced apart from the shaft receiving portion and / or the drive shaft provided in the shaft receiving portion. In particular, all disks can be rotatably mounted separately on disk shafts that are separately positioned and / or spaced apart from the shaft receiving portion and / or the drive shaft provided in the shaft receiving portion. Due to this type of arrangement of the disks, sufficient installation space for the respective gear units can be provided between the drive shaft and the corresponding disk, and thus a structurally advantageous construction can be ensured.

[0014] According to a more advantageous design embodiment, at least two disk shafts can be positioned transversely to the longitudinal extension of the respective shaft receiving portion, so as to have different spacings from the shaft receiving portion and / or the drive shaft provided in the shaft receiving portion. As a result, the disks respectively provided on the disk shafts can also be differently positioned in a direction transverse to the longitudinal extension of the respective shaft receiving portion. Due to this mutually offset arrangement of the disk shafts or disks, the disks can respectively ensure different torque inputs to the yarn to be deformed.

[0015] Similarly, at least two disk shafts can be positioned transversely to the longitudinal extension of the respective shaft receiving portion, so as to have the same spacing from the shaft receiving portion and / or the drive shaft provided in the shaft receiving portion. As a result, the disks respectively provided on the disk shafts can also be identically positioned in a direction transverse to the longitudinal extension of the respective shaft receiving portion. Thereby, an overall advantageously selected or set torque input for each disk can be ensured.

[0016] According to a more advantageous design embodiment, at least two disks may have different outer diameters. Similarly, at least two disks may have the same outer diameter. By purposefully selecting the outer diameters of the respective disks, especially taking into account the correspondingly allocated disk shafts, the torque input to the respective disks can be influenced purposefully in turn. In turn, particularly advantageous process parameters can be achieved.

[0017] According to a more advantageous design embodiment, the disk shafts of different disks can be formed separately from each other, and / or a separate disk shaft can be provided for each disk. As a result, separate mounting of the respective disks or all disks can be established, which is advantageous especially considering the different operating rotational speeds of the different disks.

[0018] According to a further preferred design embodiment, at least two disk shafts can be arranged coaxially along the axial direction. Therefore, the coaxially arranged disk shafts can ensure the coaxial alignment arrangement of the disks arranged along the axial distribution. More preferably, at least two disk shafts can be arranged spaced apart from each other transversely to the axial direction.

[0019] Additionally or alternatively, when viewed axially, three disk shafts can form a triangular arrangement. Particularly advantageously, when viewed axially, three alignment axes can form a triangular arrangement, whereby preferably a plurality of disk shafts extend along each alignment axis. This arrangement particularly advantageously enables the yarn to be post-treated to be guided between the three alignment axes and thus to be conveyed and false-twisted particularly reliably through the device disks. In particular, the yarns to be processed separately can run centrally or approximately centrally within the triangular arrangement of the alignment axes and thus also centrally between the triangular arrangements of the plurality of disks.

[0020] Additionally or alternatively, multiple sets of disk shafts can be provided, in particular three sets of disk shafts. In particular, a plurality of disk shafts defining an alignment axis can simultaneously form a set of disk shafts. Similarly, a plurality of disk shafts substantially defining an alignment axis can form a set of disk shafts. In particular, a set of disk shafts can be arranged aligned or substantially aligned with each other in a stacked manner.

[0021] According to a favorable design embodiment, at least two disk shafts in a set of disk shafts can be transversely positioned relative to the longitudinal extension of the corresponding shaft receptacle, so as to have a different spacing from the shaft receptacle and / or the drive shaft provided in the shaft receptacle. Similarly, at least two disk shafts in such a set of disk shafts can be transversely positioned relative to the longitudinal extension of the corresponding shaft receptacle, so as to have the same spacing from the shaft receptacle and / or the drive shaft provided in the shaft receptacle.

[0022] According to a more preferred design embodiment, at least one gear unit can be designed as a traction device gear unit, in particular a belt gear unit. Particularly preferably, all gear units can be designed as belt gear units. Such gear units are low in procurement cost and ensure particularly reliable force or motion transmission between the corresponding drive shaft and the corresponding disk.

[0023] According to a more favorable design embodiment, the device can be equipped with at least one support device on which one of the disks and / or one of the disk shafts and / or one of the gear units is provided. Such a support device can be provided with little structural complexity while ensuring a robust overall construction of the device.

[0024] More preferably, such support devices can be assembled and / or capable of being assembled modularly together with another and / or adjacent support device. In this way, the device can be assembled according to the corresponding specific application. Due to this design embodiment, the device can also be subsequently adapted or flexibly adapted to improve the process parameters.

[0025] Advantageously, support devices with different gear units and / or gear ratios and / or with different positions of the disc shafts can be assembled modularly for the respective application conditions. In particular, the process parameters for the respective yarn deformation can be advantageously influenced by a targeted selection of a plurality of modules with different specifications. As a result, the operating characteristics of the device can generally be flexibly set for the respective deformation tasks or for the respective application conditions.

[0026] According to a more preferred design embodiment, the support device can have connecting parts and / or centering and / or alignment means for connection to an adjacent support device. In particular, all support devices can in each case be equipped with connecting parts and / or centering and / or alignment means for connection to an adjacent support device. As a result, a simple and precise connection can be established between at least two or all support devices.

[0027] Additionally or alternatively, the support device can have a shaft receiving part, where the shaft receiving part is preferably formed by the shaft receiving parts of a plurality of support devices. In the assembled position of the support device, the shaft receiving parts of the respective support devices can in particular be coaxially aligned. In this way, a shaft receiving part can be formed by assembling the support devices, and the drive shaft can be reliably positioned or installed therein with only little complexity.

[0028] According to a more advantageous design embodiment, the support device and the discs and / or disc shafts provided thereon, and / or the gear units provided thereon, can form a disc device, in particular a disc device in the form of an insert cassette construction. Additionally preferably, such a disc device can have operating characteristics that are defined by the gear ratio of the gear unit and / or by a predetermined spacing between the shaft receiving part of the support device and the disc shaft. The operating characteristics can in particular be pre-known so that at least one disc device that is respectively suitable for a potential specific application or application conditions can be selected with little complexity and can be assembled together with at least another disc device.

[0029] According to a more preferred design embodiment, at least two disc devices can have mutually different operating characteristics and / or mutually different gear ratios of the respective gear units, and / or different spacings between the respective shaft receiving parts of the support device and the respective disc shafts. Due to these different disc devices, the overall operating characteristics of the device or the respective process parameters can be set or adapted particularly advantageously for the respective application conditions.

[0030] According to a more preferred design embodiment, at least one disc device may have color markings, in particular color markings indicating operating characteristics. Thus, different disc devices with different operating characteristics may also have different color markings. In this way, the selection and assembly of multiple disc devices can be simplified. As a result, the risk of assembly errors is reduced.

[0031] According to a more advantageous design embodiment, the overall characteristics for the false-twisting of synthetic yarns can be set by the modular assembly of at least one disc device with at least one other disc device and / or with another support device. Additionally or alternatively, the overall characteristics for the false-twisting of synthetic yarns can be changed by replacing, adding, and / or removing disc devices. In this way, a high degree of flexibility and operational reliability in the false-twisting of synthetic yarns can be ensured.

[0032] According to a more preferred design embodiment, at least one gear unit may have a subsequently variable and / or variably adaptable gear ratio. Additionally or alternatively, the spacing between the disc shaft and the shaft receiving portion can be subsequently variable and / or variably adaptable. In this way, even without replacing or selecting the assembly of individual disc devices, the overall characteristics of the device can be set or adapted to the corresponding application conditions. In particular, subsequent adaptation can also be carried out thereby.

[0033] According to a more advantageous design embodiment, at least one disc or a plurality of discs can be designed as friction discs. This type of friction disc is particularly suitable for applying torque input to synthetic yarns. Additionally or alternatively, at least one disc can be designed and / or arranged as an inlet disc, and / or at least one disc can be designed and / or arranged as an outlet disc. The outlet disc here can have a conical cross-section. As a result, the deformation of the synthetic yarn can be particularly advantageously promoted. The inlet disc and / or the outlet disc can in particular differ from at least one other disc of the device in terms of material and / or shape.

[0034] The discs for contacting the synthetic yarn, in particular friction discs, inlet and / or outlet discs, can be formed from plastic materials, in particular polyurethane, and / or from ceramic materials. Plastic discs can be provided in a particularly cost-effective manner. Discs made of ceramic materials are particularly wear-resistant and / or can have a coefficient of friction different from that of plastic discs. Similarly, this type of disc can also be made of steel. In particular, the outlet disc in the form of a vane disc can be made of ceramic or chrome-plated steel.

[0035] Another independent aspect of the present invention relates to a device for the false-twisting of synthetic yarns, in particular a device according to one of the above aspects, having a plurality of disc devices, each of which in each case has at least one disc for contacting the synthetic yarn, wherein at least two disc devices are assembled together in a modular manner, and wherein, due to the modular assembly of at least two disc devices, the operating characteristics for mechanical twisting and / or contacting the synthetic yarn are set.

[0036] This device can be assembled according to the corresponding specific application or the corresponding application conditions. Additionally or optionally, due to modular assembly, this device can be subsequently adapted or flexibly adapted separately to improve process parameters.

[0037] Another independent aspect of the present invention relates to a device for false-twisting synthetic yarns, in particular a device according to one of the above aspects, which has a plurality of disks for contacting the synthetic yarn, has a plurality of disk shafts for rotatably mounting the disks, and has a shaft housing for at least one drive shaft for driving the disks, wherein at least two of the disk shafts have different spacings from the shaft housing.

[0038] Another independent aspect of the present invention relates to a device for false-twisting synthetic yarns, in particular a device according to one of the above aspects, which has a plurality of disks for contacting the synthetic yarn, wherein at least two of the disks have different outer diameters.

[0039] Another independent aspect of the present invention relates to a disk device for false-twisting synthetic yarns, in particular a disk device for a device according to one of the above aspects, which has a support device, has a disk rotatably mounted on the support device, has a gear unit for transmitting motion from a drive unit to the disk, and has a connection part for modular connection with a connection part of another and / or an adjacent-positionable disk device.

[0041] Therefore, the device can be appropriately adapted through such a modular system to adapt to the corresponding deformations to be carried out. The overall characteristics of the device can be subsequently adapted with only little complexity, thereby ensuring a high degree of application flexibility.

[0042] Another aspect of the present invention relates to a synthetic yarn texturing device, which has a false-twisting device according to one of the above aspects, and / or has a disk device according to one of the above aspects, has a heating device for heating the synthetic yarn in a twisted state, and / or has a cooling device for cooling the synthetic yarn in a twisted state, in particular by cooling the yarn heated by the heating device.

[0043] Due to this device, it is possible to deform synthetic yarns particularly advantageously while reducing the risk of unstable yarn running. Overall, a high production rate can be ensured.

[0044] The preferred design embodiments and advantages described above in the context of a device for false-twisting synthetic yarns apply analogously to the disc system according to the invention, the modular system according to the invention, and the synthetic yarn deformation device according to the invention.

[0045] The invention will be described below by way of example with reference to the drawings, in which in each case it is schematic:

[0051] Figure 6 A perspective view of the support device is shown Figure 5 ; and

[0052] Figure 7 A synthetic yarn deformation device according to an exemplary embodiment of the invention is shown.

[0053] Figure 1 An exemplary embodiment of a device 10 for false-twisting synthetic yarns (not shown in more detail here) according to an exemplary embodiment of the invention is schematically shown. The device 10 can in particular be a so-called false-twisting device or friction device.

[0054] The device 10 for false-twisting synthetic yarns is equipped with a plurality of discs 12 for contacting the synthetic yarn, at least one shaft receiving part 14 for driving the shaft, and a plurality of gear units 16 (as shown for example in Figure 4 ). For the sake of clarity, the gear units 16 are not shown in Figure 1 .

[0055] The gear unit 16 is in each case designed to transmit motion between at least one disk 12 and a drive shaft that can be arranged in the shaft receptacle 14 and is likewise not shown in more detail here.

[0056] In each case, at least some or all of the disks 12 can be assigned an individual gear unit 16. Here, all gear units 16 can be arranged to transmit motion from a single drive shaft. In particular, exactly one drive shaft, which is preferably coupled to a drive motor, can be arranged in the shaft receptacle 14.

[0057] At least one gear unit 16 can have a different gear ratio than one of the other gear units 16. Additionally or alternatively, a plurality of gear units 16 can have the same gear ratio.

[0058] In each case, the disks 12 are rotatably mounted on disk shafts 18 that are separately positioned and / or spaced apart from the shaft receptacle 14 and / or the drive shaft arranged in the shaft receptacle 14. At least two disk shafts 18 can be positioned transversely to the longitudinal extent of the respective shaft receptacle 14 such that they have a different spacing from the shaft receptacle 14 and / or the drive shaft arranged in the shaft receptacle 14. Likewise, at least two disk shafts 18 can be positioned transversely to the longitudinal extent of the respective shaft receptacle 14 such that they have the same spacing from the shaft receptacle 14 and / or the drive shaft arranged in the shaft receptacle 14.

[0059] The disk shafts 18 of different disks 12 can in particular be formed separately from one another. Thus, a separate disk shaft 18 can be provided for each disk 12. At least two disk shafts 18 can be arranged coaxially aligned axially. For example, the disk shafts 18a, 18b, 18c can be arranged coaxially aligned with one another. Likewise, for example, the disk shafts 18d, 18e, and 18f can be arranged coaxially aligned with one another.

[0060] Furthermore, at least two disk shafts 18 can be arranged spaced apart transversely to the axis, for example the disk shafts 18a and 18d, or the disk shafts 18b and 18e.

[0061] When viewed axially, three disk shafts 18 can in particular form a triangular arrangement. Particularly advantageously, when viewed axially, three alignment axes can form a triangular arrangement, with a plurality of disk shafts 18 extending along each alignment axis. For example, the disk shafts 18a, 18b, and 18c can lie on one alignment axis or define one alignment axis. Likewise, the disk shafts 18d, 18e, and 18f can lie on one alignment axis or define one alignment axis. According to Figure 1 the illustration, the third alignment axis with the other disk shafts 18 is mostly obscured. The arrangement with three alignment axes particularly advantageously enables the yarn to be processed to be guided between the three alignment axes.

[0062] From Figure 4 As can be seen from the view of Figure 4 , the gear unit 16 can be a traction device gear unit, preferably a belt gear unit. Additionally preferably, all gear units 16 of the device 10 can be designed as belt gear units.

[0063] More preferably, the device 10 can have a plurality of support devices 20, on which one of the disks 12 and / or the disk shaft 18 and / or one of the gear units 16 is / are provided.

[0064] Figures 2 to 4 A first exemplary embodiment of the support device 20 is shown, and another exemplary embodiment of the support device 20 is shown in Figure 5 and Figure 6 The support device 20 is preferably designed to be assembled or capable of being assembled modularly together with another and / or adjacent support device 20. The assembly positions of the plurality of support devices 20 are schematically shown in Figure 1 The support device 20 has a connecting portion 22 and / or centering and / or alignment means 24 for connection to an adjacent support device 20. Additionally, in each case, these support devices can have a shaft receiving portion 26, wherein the shaft receiving portion 14 is preferably formed by the shaft receiving portions 26 of a plurality of support devices 20.

[0065] In each case, the support device 20 and the disk 12 and / or the disk shaft 18 provided thereon, and / or the gear unit 16 provided thereon, can particularly preferably form a disk device 28, especially a disk device 28 in the form of a plug-in cassette construction. According to the illustration of

[0066] a plurality of disk devices 28 are assembled in the form of a plug-in cassette construction in each case, especially in a modular manner, so as to form the device 10. Figure 1 Each disk device 28 can preferably have operating characteristics that are defined by the gear ratio of the corresponding gear unit 16 and / or by a predetermined spacing between the shaft receiving portion 26 of the support device 20 and the disk shaft 18.

[0067] Within the device 10, at least two disk devices 28 can have mutually different operating characteristics and / or mutually different gear ratios of the corresponding gear units 16, and / or different spacings between the corresponding shaft receiving portions 26 of the support device 20 and the corresponding disk shafts 18.

[0068] Due to the modular assembly of at least one disk device 28 and at least another disk device 28 as shown in

[0069] Since Figure 1 Figure 1 , the overall characteristics of the device 10 for synthetic yarn false twisting can be set, and / or the overall characteristics for synthetic yarn false twisting can be changed by replacing, adding, and / or removing disk devices 28.

[0070] At least one gear unit 16 may have a subsequent variable and / or variably adaptable gear ratio, and / or the spacing between the disc shaft 18 and the shaft receiving portion 14 may be subsequently variable and / or variably adaptable.

[0071] The invention furthermore relates to a modular system for an apparatus 10 for false-twisting synthetic yarns, in particular for an apparatus 10 according to Figure 1 The modular system has a plurality of disc devices 28 which can be assembled modularly in order to produce the desired overall characteristics, wherein at least one disc device 28 is formed as a replacement and / or additional module, and wherein by replacing at least one disc device 28 with a replacement module, and / or by adding at least one additional module, and / or by removing one of the disc devices 28, the overall characteristics of the assembled apparatus 10 for false-twisting synthetic yarns are variable.

[0072] Figure 7 FIG. schematically shows a device 30 for deforming a synthetic yarn 32. The device 30 for deforming a synthetic yarn 32 may have an apparatus 10 for false-twisting the synthetic yarn 32. Furthermore, such a device 30 may have a heating device 34 for heating the synthetic yarn 32 in the twisted state, and / or a cooling device 36 for cooling the synthetic yarn 32 in the twisted state. The apparatus 10 for false-twisting the synthetic yarn 32, the heating device 34 and the cooling device 36 may form a so-called deformation zone.

[0073] The device 30 may also be equipped with a supply station 38 for receiving a supply bobbin 40. Furthermore, the device 30 may have an upper yarn guide 42, an input godet roller 44 and an output godet roller 46. The deformation zone may in particular be arranged between the input godet roller 44 and the output godet roller 46.

[0074] In the deformation zone, a false twist can be generated on the synthetic yarn 32 by means of the apparatus 10. In this exemplary embodiment, the apparatus 10 is in particular formed by a friction device, preferably as described above in connection with Figures 1 to 6 By means of which the synthetic yarn 32 is mechanically twisted. The false twist thus formed propagates in a direction opposite to the yarn running direction of the yarn 32 and passes through the cooling device 36 and the heating device 34.

[0075] As Figure 7 shown, the yarn 32 is continuously withdrawn from the supply bobbin 40 by the input godet roller 44. For this purpose, the supply bobbin 40 can be held in the supply station 38, whereby the yarn 32 can be withdrawn by means of the upper yarn guide 42. The yarn 32 can at the same time be drawn in the deformation zone. Thus, the output godet roller 46 can run at a higher circumferential speed, so that a speed difference required for drawing is established between the input godet roller 44 and the output godet roller 46.

[0076] In the deformation zone, the false-twisted yarn 32 can be heated to the yarn temperature, for example, in the range of 200 °C, in the heating device 34. Since the yarn is heated, the false twist can be incorporated as crimp, in particular, into the corresponding monofilaments. This crimp is then fixed by intensive cooling in the cooling device 36.

[0077] Due to the design embodiment of the device 10, in particular by providing at least one gear unit 16 for at least one disk 12, or in each case one gear unit 16 for each disk 12, the device 10 can operate with particularly favorable process parameters. Therefore, the device 30 can ensure high overall productivity.
