Description

Field of the Invention

[0001] The present invention relates to a winding device for winding a plurality of synthetic filaments, which has a godet roller area for withdrawing and conveying a plurality of synthetic filaments and an overhead godet unit for automatically distributing these synthetic filaments through a plurality of overhead godet rollers. Background Art

[0002] Winding devices with overhead godet guides for automatically distributing a plurality of synthetic filaments are known from the general prior art.

[0003] DE102021002456A1 discloses a winding device which has a plurality of thread laying positions that are formed adjacent to each other in parallel on a driven winding spindle and have a thread laying unit and an overhead godet guide. The overhead godet guide is movably held by a guiding device and can be selectively guided to a working position in the thread laying position and a splicing position outside the thread laying position.

[0004] WO2022033919A1 discloses a device for withdrawing and winding filaments. The thread laying device of the device has a displaceable overhead godet guide for each thread laying position, which can be reciprocally guided between a splicing position and a working position for distributing the filaments to the winding stations. In order to enable the filaments to be spliced on the first godet roller and the second godet roller without any operator activity, the thread laying device has a displaceable splicing roller, which is in the region between the first and second godet rollers and can be guided between a splicing position for engaging the filaments on the godet roller circumferential surface and a working position.

[0005] With the help of the overhead godet guide, the filaments are grasped and guided to the relevant yarn laying positions.

[0006] In a device for withdrawing and winding filaments with a splicing roller, the filaments spliced on the godet roller and the splicing roller in the working position form a filament group.

[0007] However, the second godet roller can deflect the filament position away from the filament group. Depending on the filament tension, the friction between the filament and the second godet roller, and the ratio of the filament speed to the circumferential speed of the second godet roller, the filament is deflected to a variable degree. In practice, the result is that the filament position is not clearly defined, so there is uncertainty when grasping the filament with the overhead godet guide. Summary of the Invention

[0008] Therefore, the object of the present invention is to provide a winding device by which the mentioned problems can be prevented or at least alleviated.

[0009] The present invention achieves this object by a winding device.

[0010] According to one aspect of the present invention, there is provided a winding device for winding a plurality of synthetic filaments, which has a godet roller area for withdrawing and conveying the plurality of synthetic filaments and an overhead filament guiding unit for automatically distributing these synthetic filaments through a plurality of overhead filament guides, and these overhead filament guides guide these synthetic filaments at a plurality of filament dropping positions of the filament dropping device of the winding device. The joints of these synthetic filaments on the plurality of overhead filament guides are thus supported by a filament orienter, i.e., each of the filaments can be assigned to an overhead filament guide, and in particular can be jointed on the overhead filament guide in a singularized manner.

[0011] With the help of the filament orienter, precise and definite positioning of the filaments in the relevant overhead filament guides can be achieved, without any unwanted deflection of the filaments in the winding device that could lead to misalignment or failure of the joints on the relevant overhead filament guides.

[0012] In this way, it can be ensured that the jointing process of the plurality of synthetic filaments at the filament dropping positions can generally be successfully carried out with the help of the overhead filament guides.

[0013] According to a design embodiment of the winding device, the filament orienter can be displaced between a parked position and a jointing position. In the parked position, the filament orienter is located outside the filament path, and in the jointing position, the filament orienter engages on the filament path.

[0014] The filament orienter is preferably assembled in a manner that can be moved through a guide in the godet roller area bracket of the winding device. This allows the filaments to be automatically and reliably guided to the overhead filament guides when the filament orienter is in the jointing position, because unwanted dropping and movement of the filaments in the godet roller area do not occur.

[0015] According to another design embodiment of the winding device, the filament orienter can be moved to the jointing position and / or the parked position in a linear, curved and / or pivotable manner through a guiding mechanism.

[0016] The guiding of the filament orienter can be achieved in various different design embodiments. For example, linear, curved and / or circular gate guides can be provided, where the filament orienter can be displaced between the jointing position and the parked position.

[0017] According to another design embodiment, the filament orienter can also be moved or pivoted to the jointing position and the parked position so as to be pivotable or rotatable at a predetermined position. According to a specific design embodiment, the filament orienter is attached to a displaceable and / or pivotable joint arm.

[0018] According to another design embodiment of the winding device, the thread director has a groove for each thread, which is laterally delimited by fork teeth for singularizing the threads.

[0019] The exact singularization and positioning of the threads can be carried out by the thread director and the associated grooves, the number of grooves corresponding to the threads to be deposited or aligned, so that the overhead thread guides can precisely grasp the associated threads in order to correspond to the deflection caused by the laterally spaced grooves and move the threads to the associated thread deposition positions. Therefore, the overhead thread guides are laterally spaced from each other at a predetermined spacing. The spacing of the overhead thread guides is taken into account in the lateral spacing of the grooves of the thread director.

[0020] According to another design embodiment of the winding device, the groove has a receiving portion and a guiding portion, wherein the receiving portion and the guiding portion are arranged relative to each other and / or offset from each other.

[0021] The groove of the thread director can be divided into a receiving portion in which the thread is received in the groove and a thread guiding portion in which the thread is aligned and guided.

[0022] Depending on the required alignment, the positions of the receiving portion and the thread guiding portion can be arranged such that both are arranged opposite each other in the same line. However, it may also be necessary for the thread guiding portion to allow different positioning of the threads, in which the thread positions are in particular closer to or further apart from each other, such that the thread guiding portion and the receiving portion are positioned differently.

[0023] For example, the threads in the thread guide roller area can be supplied to the thread director at too large a spacing, such that the overhead thread guides can grasp the threads in the correct position. In this case, the receiving portion is positioned at a greater spacing than the thread guiding portion in order to grasp the more widely spaced threads, such that the overhead thread guides can also correctly position the threads accordingly and guide the threads to the thread deposition positions.

[0024] According to another design embodiment of the winding device, the thread director is designed to concentrate the threads in such a way as to reduce the thread spacing in order to consistently hold the threads, thus maintaining a constant thread spacing, and / or to spread the threads, in which case the thread spacing is increased.

[0025] According to this design embodiment, the thread director is correspondingly aligned for each case. It is therefore also conceivable that the thread director has adjustable grooves such that the corresponding change in the thread spacing can be adjusted for each purpose.

[0026] According to another design embodiment of the winding device, the thread director has a plurality of grooves, each of which is laterally delimited by fork teeth and formed on a shank, wherein the shank can be fastened to a joint arm.

[0027] For better positioning, the thread aligner can also be assembled and fixed to the joint arm. Here, corresponding threaded connections can be provided for fixing and loosening relative to the joint arm.

[0028] Alternatively, if the dimensions and structural design do not require or permit a joint arm, the thread aligner can also have a corresponding gate guide on the winding device.

[0029] According to another design embodiment of the winding device, the joint arm is located between the convergence position formed by the convergence forming device and the thread guide roller in the thread guide roller area.

[0030] The convergence position is hereby understood to mean the position or location where a plurality of threads are joined together so that the threads can be better joined and positioned at the winding position of the winding device, the thread guide roller area, and the thread dropping unit.

[0031] In short, the concentration of a plurality of threads occurs at one position.

[0032] This can be, for example, the hole of a suction gun where the threads are joined together to form a thread bundle.

[0033] According to another design embodiment of the winding device, the convergence forming device for collecting the threads is formed on the guide rail and can move between a parked position outside the thread path and a convergence position for collecting the threads.

[0034] The convergence forming device can be an inclined guide rail that joins the threads to form a thread bundle, thereby enabling better joining of the threads and better single-threading of the threads with the aid of an automatic thread dropping device such as an overhead thread guide.

[0035] The convergence forming device is particularly only used when joining the threads and dropping them into the convergence position by means of an overhead thread guide. Therefore, the convergence forming device can advantageously be moved in such a way that it can shift, pivot, and / or move between a parked position outside the thread path and a convergence position for collecting the threads inside the thread path.

[0036] According to another design embodiment of the winding device, the convergence forming device is formed by the hole of a suction gun that is arranged in the area of the winding spindle of the winding device in such a way that it is located below the winding spindle.

[0037] Before joining at individual positions in the thread guide roller area, the threads, thread bundles, or plurality of threads to be joined are optimally joined together at the convergence position first. The convergence position can be formed by the convergence forming device.

[0038] In its simplest form, the converging position can also be a suction gun that sucks up the filaments that have not yet been deposited and guides the filaments to the waste filament area. As long as the filaments extruded by the melt spinning device are not fully joined at the winding device and cannot be wound onto the bobbin, the filaments have to be collected accordingly so that the filaments can be joined without defects in the winding device.

[0039] According to another design embodiment of the winding device, the godet roller area has a first godet roller and a second godet roller for withdrawing and transporting a plurality of synthetic filaments, wherein the first and second godet rollers are arranged successively in the filament running direction, wherein the overhead godet unit is arranged behind the second godet roller in the filament running direction, and wherein the filament aligner is located between the second godet roller and the overhead godet unit and / or behind the overhead godet unit in the filament running direction.

[0040] According to the design embodiment of the winding device, it is possible that the filament aligner is positioned at different positions on, behind, in front of, or after the godet roller area.

[0041] This is the result of the structural prerequisites, the positions of the godet rollers, and the profile of the overhead godet unit of the winding device, so different positions of the filament aligner can be generated therefrom. Description of the Drawings

[0094] Figure 1 The winding device 20 according to the present invention having a guide wire roller area 10, a winding spindle area 30 and a silk thread orientator 40 is shown in a sectional schematic view.

[0095] The guide wire roller area 10 has a first guide wire roller 8 and a second guide wire roller 9, by means of which one silk thread F, in particular a plurality of silk threads F, extruded by a melt spinning device (not shown) is drawn out and conveyed towards the winding spindle area 30.

[0096] A plurality of filaments F are guided along a filament cutting device 4 having a suction system 2 in the filament running direction FR through a first entanglement unit 6 for pre-winding the filaments of the respective filaments F to a first godet roller 8 and through a joining roller 16 that can be moved between a parking roller position RPP and a joining roller position RAP in a joining guide 18 to a second entanglement unit 7 for additional winding of the filaments of the respective filaments F until a second godet roller 9.

[0097] The relevant components of the godet roller area 10 are assembled in a manner that can be moved in a godet roller area bracket 1.

[0098] The joining roller 16 can be moved in the joining guide 18 between a parking roller position RPP and a joining roller position RAP.

[0099] Figure 1 The joining roller 16 in [description] is in the joining roller position RAP as shown in the figure.

[0100] The joining roller 16 supports the joining of a plurality of filaments F on the second godet roller 9.

[0101] Before joining a plurality of filaments F on the second godet roller 9, these filaments are directly guided to a suction gun 50 at the foot end of a winding device 20 in the area of the winding spindle 30.

[0102] These filaments F are sucked in the filament running direction by means of the suction gun 50. Then, the joining roller 16 is moved along the joining guide 18 from the parking roller position RPP to its joining roller position RAP, as a result of which a plurality of filaments F are joined on the second godet roller 9 by the second entanglement unit 7.

[0103] Subsequently, a plurality of filaments F are deposited at relevant filament dropping positions 22.1 - 22.n by means of an overhead godet unit 12 and a plurality of overhead godet guides 14 movably assembled in the overhead godet unit 12, where the number of filament dropping positions 22.1 - 22.n corresponds to the number of filaments to be deposited, and this also applies to the number of overhead godet guides 14.

[0104] For better understanding and simplified display, in Figure 1 the illustrated embodiment, four overhead godet guides 14 are shown. The number of overhead godet guides 14 corresponds to the number of filament dropping positions 22.1 to 22.n and can be more or less than four in other embodiments (not shown).

[0105] By means of a relevant filament dropping device 21, the filaments are wound at the filament dropping positions 22.1 - 22.2 to form a winding bobbin 33. For this purpose, a bobbin tube 32 can be placed on the first and second winding spindles 31.1 and 31.2.

[0106] The second winding spindle 31.2 is located at the winding position WP, while the first winding spindle 31.1 is located at the doffing position DP. In the winding position WP, with the help of the thread laying device 21 and the rotating winding spindle 31.2, multiple filaments can be wound to form a wound bobbin 33.

[0107] Once the wound bobbin 33 has been wound to a predetermined degree, the first and second winding spindles 31.1, 31.2 can be shifted to the doffing position DP or the winding position WP by a turntable (not shown).

[0108] When shifting the respective winding spindles 31.1, 31.2, the multiple filaments F are cut accordingly, so that the wound bobbin 33 in the doffing position DP can be removed from the winding spindles 31.1, 31.2, and the newly arrived filaments can be spliced and wound onto the bobbins 32 on the winding spindles 31.1, 31.2 at the winding position WP on the winding spindles 31.1, 31.2.

[0109] Figure 2 and Figure 3 The first winding unit 6 and the second godet roller 9 are shown in a simplified side view. Also shown is the gripping line FL, which is shown in Figure 1 and the overhead thread guide 14 single-splices these filaments F at the gripping line.

[0110] Figure 2 The filament profiles of the multiple filaments F on the second godet roller 9 and the gripping line FL are shown in a simplified manner.

[0111] Here, these filaments F form a substantially triangular filament profile up to the convergence position KS, which is formed by the suction gun 50, and the overhead thread guide 14 is positioned in a predetermined manner corresponding to the triangular profile.

[0112] Due to the friction and additional movement of the godet roller 9, the triangular profile can expand, as a result of which the spacing between the multiple filaments F in the region of the gripping line FL increases, and as a result, the overhead thread guide 14 can respectively unfavorably fail to grasp the filaments F or grasp the wrong filaments F, as Figure 3 shown.

[0113] To avoid this situation, according to the present invention, a filament orienter 40 is provided, which can prevent such changes and fluctuations of the multiple filaments at the picking line position F11.

[0114] Figures 4 to 6 Shown is the splicing and single-splicing of the multiple filaments F with the help of the filament orienter 40 when interacting with the overhead thread guide 14.

[0115] In Figure 4In this case, the thread or threads F have already been joined in the first winding unit 7, the first thread guide roller 8 and the second winding unit 7 as well as the second thread guide roller 9, which can also be seen from the fact that the joining roller 16 has left the elevated parking position PKP, see Figure 1 .

[0116] Furthermore, the converging forming device 60 is positioned at the converging position KS in such a way that a plurality of threads F are joined at the converging forming device 60 and can be sucked in uncomplicatedly by the suction gun 50.

[0117] The elevated thread guide 14 has not yet come into contact with the relevant thread F. This also applies to the thread aligner 40 according to the invention, which is still in its parking position PK.

[0118] In Figure 5 , the thread aligner 40 has been moved to the joining position AP and has come into contact with a plurality of threads F, where the threads F are inserted into the grooves 42 of the thread aligner 400 (see Figures 7 to 9 ).

[0119] The elevated thread guide 14 now moves individually from the elevated parking position PKP to the elevated joining position AKP, where the first elevated thread guide 14 has not yet engaged a plurality of threads F.

[0120] In Figure 5 , the first elevated thread guide 14 is about to pick up one of the threads F and move it via the elevated thread guide unit 12 to a predetermined thread dropping position 22.1 - 22.n. The elevated thread guides 14 are laterally offset from each other in the transverse direction of the elevated thread guide unit 12 such that each elevated thread guide 14 can grasp one of the threads F from a plurality of threads F.

[0121] In Figure 6 , each elevated thread guide has picked up a relevant thread F and displaced it to the relevant thread dropping position 22.1 - 22.n and the converging forming device 60 is no longer in contact with the plurality of threads F and is pivoted to the parking station PPK.

[0122] Then, the plurality of threads F at the thread dropping positions 22.1 - 22.2 are transferred to the thread dropping device 21 and are placed on the tube 32 of the winding spindle and are all wound to form a winding bobbin 33 through a further joining process.

[0123] Figures 7 to 9 Shows different embodiments of the thread aligner 40, which have different designs and arrangements of the grooves 45.

[0124] As Figure 7As shown, the filament aligner 40 has a prong or tooth 41 that defines a groove 42. The prong or tooth 41 is formed on the shank 43. The groove 45 can be subdivided into a receiving portion 44 and a guiding portion 45.

[0125] The receiving portion 44 is used to pick up the filament F or insert the filament into the guiding portion 45, which ensures that the filament F is guided in a Figure 7 constant manner as shown, in a Figure 8 converging manner as shown and / or in a Figure 9 diverging manner as shown.

[0126] To collect or disperse the filament F, the receiving portion 44 and the guiding portion 45 are offset from each other. During dispersion, the guiding portions 45 are spaced further apart than the receiving portion 44. For collection, the guiding portions 45 are arranged more densely than the receiving portion 44, where the spacing of the respective adjacent receiving portion 44 or guiding portion 45 is to be considered.

[0127] Figures 10 to 14 Different embodiments of the filament alignment guiding mechanism 47 of the filament aligner are shown.

[0128] In Figure 10 , the filament alignment guiding mechanism 47 is aligned in a convex manner such that the filament aligner 40 follows a generally circular contour from the parked position to the aligned position.

[0129] In Figure 10 , the filament aligner 47 is implemented in a substantially linear or translational manner such that the filament alignment can be displaced along a direct path that extends linearly from the parked position to the joint position.

[0130] The filament aligner 40 is shown in Figure 12 to be pivotable from the parked position to the aligned position through a pivot point.

[0131] In Figure 13 , the filament aligner is disposed below the overhead wire guiding unit 12.

[0132] In Figure 14 , the filament aligner 40 is movably mounted on the joint arm 49. The joint arm 49 has a combination of convex and linear filament alignment guiding mechanisms 47.
