Description

[0001] The present invention relates to a winding device for winding filament bundles onto spools to form bobbins, which has been specially designed to facilitate the automatic feeding of yarn onto the winding device.

[0002] The closest prior art, WO2021144300A1, discloses a winding device, but it is not capable of automatically threading yarn onto the winding device. This limitation necessitates manual intervention, which can be time-consuming and inefficient.

[0003] The object of the present invention is to provide a winding device that enables automatic feeding of filament bundles onto the winding device.

[0004] The problem is solved according to the invention with a winding device having the features according to claim 1.

[0005] According to one aspect of the invention, a winding device for automatically distributing filament bundles is provided, wherein the winding device has a plurality of winding positions at which a plurality of filament bundles can be wound onto a plurality of spools to form a spool, wherein the spools can be mounted on a spindle at the winding positions, wherein a plurality of thread guides can be guided in a guide track which is positioned above and spaced apart from the spindle, wherein the guide track has a first track section on which the plurality of thread guides are parked in a parking position, and a third track section on which the plurality of thread guides are distributed in a positioning position for the winding position, wherein the first track section extends away from the spindle and substantially perpendicular to the third track section.

[0006] A winding device is a device with which a plurality of synthetic threads or filament bundles, which are made from a plastic melt, can be wound onto spindles and sleeves to form spools.

[0007] The spindle can be a chuck with a device for releasably locking sleeves on which the filament bundles are wound into coils.

[0008] The plastic melt is extruded above the winding device via spinnerets into filaments, which are extruded from the spinnerets in the thread direction towards the winding device.

[0009] A guide track, in which a number of thread guides are guided, is positioned above the spindle in the winding device. The guide track is arranged in the opposite direction to the thread travel direction of the spindle.

[0010] According to a preferred embodiment of the winding device, the guide track has a second track section that connects the first track section and the third track section in such a way that the first track section is angled to facilitate the movement of the thread guides from the park position to the winding positions.

[0011] The track sections of the guideway are continuously mounted next to each other. The guideway can also be single-level, whereby the desired shape can be achieved by curving the guideway and / or by forming it in a mold.

[0012] According to a further preferred embodiment of the winding device, the majority of thread guides are movable between the parking position and the application position, wherein in the parking position the majority of thread guides are arranged essentially adjacent to each other, and in the application position they are spaced apart from each other.

[0013] In The thread guides are gathered side by side in the parking position, so that little space is needed and the track section is designed so that all thread guides have enough space.

[0014] In the feed position, the thread guides for feeding the filament bundle to the corresponding winding position are spaced apart from each other, so that even a changing unit positioned in a changing housing can grip the corresponding filament bundle. The changing unit enables the formation of a spool.

[0015] According to a particularly preferred embodiment of the winding device, the third web section is spaced apart in a first plane and extends essentially parallel to the spindle and is inclined in a second plane with a guide rail inclination angle, so that one end section of the third web section, which is positioned adjacent to a galette, has a greater distance to the spindle than the other end section of the third web section, which is inclined towards the spindle.

[0016] Depending on the viewing direction of the winding device, the track sections of the guide track are arranged in a respective plane either parallel to the spindle, perpendicular to the spindle and / or inclined to the spindle.

[0017] According to a preferred embodiment of the winding device, the thread guides are mounted on a thread guide holder which is movable along the guide track, with the distance between the thread guide holder and the guide track increasing with each winding position.

[0018] A number of yarn bundles are wound onto the winding device. For this purpose, the yarn bundles are guided along guide rails at a predetermined interval. A yarn catcher is provided for each yarn bundle, projecting from the guide rail at a predetermined distance so that it can grasp the corresponding yarn bundle and convey it to the appropriate winding position.

[0019] According to a further preferred embodiment of the winding device, the distance between the guide track and the thread guide holder is greatest at the first winding position and smallest at the nth winding position, so that each thread guide holder can grasp a bundle of thread.

[0020] The distance between the thread guide and the guide rail depends on the corresponding winding position. Ideally, the distance between the thread guide and the guide rail is greatest for the first winding position and not decreases for each subsequent winding position.

[0021] According to a particularly preferred embodiment of the winding device, the thread guide holder has a thread catcher at the end section opposite the guide track in order to catch a bundle of filament for each winding position and secure it during movement along the guide track.

[0022] To catch the filament bundle, the thread guide can have a thread catcher. The thread catcher can be a roller with a circumferential catching notch and / or a catching hook. The essential point is that the thread catcher can securely catch the filament bundle and guide it to the corresponding winding position without damaging the filament bundle.

[0023] According to a preferred embodiment of the winding device, the thread bundles are gathered together by a feed suction gun when placed at the winding positions, so that each thread bundle can be grasped by the thread guides when moving into the placement position.

[0024] The feed suction gun is designed to catch the unlaid filament bundles and guides them to a collection container. Once the filament bundles are positioned at the winding positions, they can be attached to the spools.

[0025] According to a further preferred embodiment of the winding device, the winding device has a galette carrier with a first galette and a second galette, wherein a movable feed roller for applying the filament bundle is positioned between the first galette and the second galette.

[0026] The first and second galettes pull the filament bundles from the spinneret and guide them in the direction of the thread run towards the winding positions. A movable feed roller can be moved between the galettes in a guide track to assist in positioning the filament bundles on the winding device.

[0027] According to a particularly preferred embodiment of the winding device, the winding device has a first spindle with a first spindle drive and a second spindle with a second spindle drive, each of which can be moved into a winding position for winding a coil at the respective winding positions and into an off position for removing the coil from the first and / or second spindle.

[0028] To form a coil, the spindles are rotatable around their axis and each has its own coil drives that control the rotation of the spindle, so that the spindle can be rotated at a sufficient speed to form a coil.

[0029] The interaction of the winding drives and the other components of the winding device, such as the galettes and the thread guides, is regulated and / or controlled by a control system, so that automatic placement of filament bundles on the winding device is necessary, at least without the intervention of a human operator.

[0031] The present invention relates to a winding device 1 for automatically distributing filament bundles F.

[0032] In Fig. 1 and2 The winding device 1 is shown in a longitudinal view and a side view. The number of winding positions is indicated from W1.1 to Wn, where n can be a natural number greater than 4. Depending on the length of a spindle 8, 9, the number of winding positions can exceed 4. The illustration has been simplified here. Depending on the spindle length, there may also be more or fewer winding positions than shown. The number of winding positions W1.1 to Wn also determines the number of changing devices provided in a changing housing 4 for changing the respective filament bundles F.

[0033] The winding device 1 comprises a plurality of winding positions W.1-Wn, at which a plurality of filament bundles F can be wound onto a plurality of sleeves 12 to form a spool 14.

[0034] The sleeves 12 can be mounted at winding positions W.1-Wn on a first and / or second spindle 8, 9. Above and spaced apart from the spindle 8, 9, a guide track 4 is positioned in which a plurality of thread guides 40 can be guided.

[0035] The first spindle 8 in Fig. 1 is positioned in a winding position, with 12 synthetic filament bundles wound onto the sleeve to form a spool 14.

[0036] The second spindle 9 is positioned in a Doff position, in which the finished coils 14 can be removed from the spindle.

[0037] The position of the first spindle 8 and the second spindle 9 can be changed from the winding position to the unwinding position and vice versa using a spindle turret (not shown). The invention is explained below with the first spindle in the winding position, as also illustrated in the figures.

[0038] The guide track 4 has a first track section 43, on which the majority of thread guides are parked, and a third track section 45, on which the majority of thread guides are distributed in the winding position. The first track section 43 extends away from the spindle and essentially perpendicular to the third track section 45, see also Fig 3 and 4 , which has a parking position P and Fig 5 and 6 , which show the insertion position of the thread guides in the guide track.

[0039] For example, in Fig. 3 and 5 As shown in detail, the guide track 4 has a second track section 44 which connects the first track section 43 and the third track section 45 in such a way that the first track section 43 encloses an angle to facilitate the movement of the thread guides 40 from the park position P to the winding positions W1-Wn.

[0040] In another embodiment, the majority of thread guides 40 are movable between the parking position P and the placement position A, as for example in Fig 3 and 4 displayed. In parking position P, as shown in Fig. 2 and 3 As shown, the majority of thread guides are arranged essentially adjacent to each other, while in the insertion position, as in Fig. 1 and 2 or 4 and 5 are shown, spaced apart from each other.

[0041] In Fig. 7 A detailed view shows a top view of guide track 4.

[0042] The third track section 45 extends in a first plane, spaced apart and essentially parallel to the first and second spindles 8, 9 respectively, and is inclined in a second plane with a guide track inclination angle α. As a result, one end section of the third track section 45, which is positioned adjacent to a second galette 22, has a greater distance to the spindles 8, 9 than the other end section of the third track section 45, which is inclined towards the spindles 8, 9.

[0043] Continuing with reference to Fig. 1 and 7 .

[0044] The thread guides 40 are mounted on a thread guide holder 41, which is movable along the guide track 4. The distance between the thread guide holder 41 and the guide track 4 increases with each winding position. The distance between the guide track 4 and the thread guide holder 41 is greatest at the first winding position W1 and smallest at the nth winding position Wn, so that each thread guide holder 40 can grip a thread bundle F. The guide track is inclined at the guide track inclination angle α relative to the spool spindle 8 or 9, as shown in Fig. 7 shown.

[0045] The thread guide holder 41 has a thread catcher 42 at the end section opposite the guide track 4 in order to catch a filament bundle F for each winding position and secure it during movement along the guide track 4.

[0046] The thread bundles F are gathered together by a feed suction gun 26 when applied to the winding positions, so that each thread bundle F can be grasped by the thread guides 40 when moving into the application position A.

[0047] The winding device 1 comprises a galette carrier 2 with a first galette 21 and a second galette 22, wherein a movable feed roller for applying the filament bundle F is positioned between the first galette 21 and the second galette 22.

[0048] The winding device 1 has a first spindle 8 with a first spindle drive 18 and a second spindle 9 with a second spindle drive 19, each of which can be moved into a winding position for winding from a coil 14 and into an off position for removing the coil 14.

[0049] By incorporating the guide track 4 with three track sections 43, 44, 45 and positioning them above and at a distance from the spindle 8, 9, the present invention enables the automatic feeding of filament bundles F or yarn onto the winding device 1, thereby eliminating the limitations of the prior art and improving the overall efficiency of the winding process.

[0050] The invention enables the automatic distribution and winding of filament bundles F onto spools 12, wherein the thread guides 40 are moved along a specially designed guide track 4 to ensure efficient and precise winding and to improve automatic application. Reference symbol list:
