[0001] Method and device for automatically applying a plurality of synthetic threads to a winding device
[0002] The invention relates to a method for automatically applying a plurality of synthetic threads to a winding device according to the preamble of claim 1 and to a device for automatically applying a plurality of synthetic threads to a winding device according to the preamble of claim 9 and to a system in which the method and the device are applied.
[0003] It is generally known from the prior art to load winding devices with godets, traversing devices and winding spindles semi-automatically and / or automatically with appropriate distribution devices and / or robots with the synthetic thread to be wound in such a way that a permanent winding of winding packages is possible.
[0004] However, dedicated mooring robots are very expensive and, compared to human operators, also error-prone and slow, which can lead to increased waste production during the mooring process.
[0005] The semi-automatic feeding devices regularly require the assistance of a human operator, in particular a first operator must be at the top of the spinneret or plate from which the synthetic thread is extruded and must throw it to a second operator, who is usually one or two floors below the spinneret at the level of the winding device, in such a way that the second operator can receive the extruded synthetic threads.
[0006] Only then can the winding device be applied, usually with the help of a so-called suction gun, which uses negative pressure to guide the synthetic thread into a waste container until the synthetic thread has been applied to the winding device for winding and / or stretching. Both semi-automatic and kinematic feeder robot application processes are time-consuming and expensive, require at least two operators, and are prone to errors.
[0007] The object of the invention is therefore to provide a method for automatically applying a synthetic thread to a winding device without the need for an operator to intervene.
[0008] The object of the invention is also to provide a device for automatically applying a synthetic thread to a winding device, which also functions without the assistance of an operator, as well as an associated system that combines the method and the device.
[0009] The object is achieved according to the invention with regard to a method having the features of claim 1.
[0010] The object is achieved according to the invention with regard to the device having the features of a device according to claim 9.
[0011] The object is achieved with regard to the system by a system having the features according to claim 17.
[0012] According to one aspect of the invention, a method is provided for automatically applying a plurality of synthetic threads to a winding device having a godet for withdrawing the plurality of synthetic threads from a melt extruder and a winding spindle for winding the plurality of synthetic threads and a plurality of winding positions
[0013] The tufting is carried out at tufting points from the godet to the spinning beam using automatically controllable tufting devices that define the position of a thread convergence point where the majority of synthetic threads are brought closer together. A melt extruder, for example, is understood to be a spinning beam with a spinning plate for extruding a synthetic melt.
[0014] However, a melt extruder can also be an injection molding device that has a corresponding spinning plate from which the melt can be extruded or pressed via corresponding extruders in order to produce synthetic threads.
[0015] The synthetic threads are drawn off via godets to a winding device and wound there onto bobbin tubes that are releasably locked to rotating bobbin spindles.
[0016] A landing point is understood to be a position on the winding device which is necessary for laying, transporting and guiding the synthetic thread to a corresponding traversing device and a winding spindle for winding the synthetic thread.
[0017] To support the application process, automatically controllable application means are provided which are provided on the winding device and allow the application of the synthetic thread to the respective godet, the traversing device and / or the winding spindle without the need for an additional human operator or a kinematically movable robot on the winding device.
[0018] The necessary application means are all arranged adjacent to or adjacent to the necessary positions on the winding device.
[0019] A thread convergence point is understood to mean a position on the winding device which determines a merging of the plurality of synthetic threads at a predetermined position.
[0020] A thread convergence point can, for example, be the intake port of a suction gun or a placement guide groove on the winder device, which is designed such that the plurality of synthetic threads from a thread curtain are gathered into a thread bundle. The position of the intake port is automatically and controllably shifted using an associated placement device.
[0021] According to one embodiment of the method, the plurality of synthetic threads are applied to the winding device by means of merging at the thread convergence points, which are located at different positions on the winding device, and by separating them by means of a winding position laying device.
[0022] The special feature of the method according to the invention is that for the automatic application of the plurality of synthetic threads, these are brought together from the thread curtain at predetermined thread convergence points and then separated again into spaced threads for precise positioning at predetermined winding positions.
[0023] A synthetic thread is a synthetic thread that is extruded from a plastic melt and has a large number of filaments.
[0024] A plurality of synthetic threads or a thread curtain refers to a plurality or multiplicity of synthetic threads. In a thread curtain, the synthetic threads are spaced apart from one another.
[0025] According to a further embodiment of the method, the position of the thread convergence point is arranged at different positions on the winder device depending on the respective application point on the winder device. It is important to ensure that, depending on the predetermined application point, such as a godet, a traversing device, and / or a winding position on a winding spindle, the thread convergence point is relocated accordingly on the winder device and the thread curtain is brought together for the new application position at the corresponding thread convergence point.
[0026] According to a further embodiment of the method, the thread convergence point is triggered by activating the respective automatically controllable feed device. An automatically controllable feed device is, for example, a movable pivot arm and / or a feed roller, which can be moved or automatically moved to designated thread convergence points via corresponding tracks and / or guides and / or pivot points, thus enabling correct and precise positioning of the synthetic thread at the corresponding position of the winding device.
[0027] According to a further embodiment of the method, before the plurality of synthetic threads are applied and distributed at the respective application point, a shift of an end position of the thread convergence point is performed. According to the invention, prior to the application, the threads are collected at corresponding thread convergence points. The thread convergence points move from a suction position near the winding spindles in the opposite direction of thread travel upwards to the godet, whereby the respective end positions of the shift then change, and these convergence positions move from the godet back to the winding spindle.
[0028] This is carried out solely by means of the automatic application means on the winding device, without the need for operator intervention. According to one embodiment of the method, after the plurality of synthetic threads have been collected at the respective thread convergence point, the combined plurality of synthetic threads is spaced apart into spaced-apart threads according to the associated winding position.
[0029] Gathering at the yarn convergence point facilitates the easy application of the yarns to the respective elements of the winding device. Separating the multiple yarns is necessary when the yarns are to be applied, for example, at the traversing device and / or at the winding tubes on the winding spindle.
[0030] This separation is also carried out using corresponding devices on the winding device, so that the individual synthetic thread can also be positioned at the corresponding winding position. According to a further embodiment of the method, the spacing of the combined plurality of synthetic threads is carried out counter to the running direction above and / or in the running direction below a traversing device by means of a first and / or a second winding position transfer device.
[0031] Spacing of the plurality of synthetic threads is necessary, in particular, at the associated winding positions so that the synthetic threads can be wound onto the associated winding tubes, which are arranged on the winding spindle and releasably locked.
[0032] The winding position transfer devices can, for example, have transfer rollers that can be moved to the respective winding positions via a rail and / or have corresponding thread guides that can be pivoted back and forth on a pivotally guided rail in the area of the winding spindle and can also be moved accordingly to the individual winding positions.
[0033] After the procedure has been designed, the following steps are carried out:
[0034] Providing a thread curtain made of a plurality of synthetic threads between the winding spindle and a sliding feeder at the godet
[0035] Forming a first thread convergence point at a suction opening of a suction pipe adjacent to the winding spindle,
[0036] Moving the first thread convergence point of the thread curtain to a second thread convergence point by pivoting the suction pipe towards a positioning guide groove on the winder device, whereby the thread curtain is inserted into the positioning guide groove,
[0037] Attaching the thread curtain by means of a pivoting attachment arm, which defines a third thread convergence point, to a attachment approach, which defines a fourth thread convergence point,
[0038] Inserting the thread curtain into a thread guide comb by means of a movable sliding feeder,
[0039] Applying the thread curtain to a godet by means of a feed roller, separating the thread curtain into spaced threads by means of the first winding position transfer device into associated winding positions which correspond to a traversing device for traversing the synthetic thread, pivoting the suction opening from the first thread convergence point to a sixth thread convergence point for applying the thread curtain to a second winding position transfer device,
[0040] Separating the thread curtain by means of the second winding position transfer device into corresponding winding positions on the winding spindle,
[0041] Applying the threads separated by means of the second winding position transfer device to the winding positions on the winding spindle,
[0042] By means of the above-mentioned application steps, an automatic application of a thread curtain from a melt extruder can be carried out on the winding device without the intervention of a human operator or kinematic robot, wherein the necessary application means are all arranged and designed on the winding device, so that a completely automatic application of a thread curtain to the individual winding positions is possible.
[0043] According to another aspect of the apparatus, an apparatus is provided for automatically applying a plurality of synthetic filaments to a winding apparatus having a godet for withdrawing the plurality of synthetic filaments from a melt extruder and a winding spindle for winding the plurality of synthetic filaments at a plurality of winding positions.
[0044] According to the invention, an automatic thread laying device is provided on each application spool on the winding device, which defines a thread convergence point by means of which the synthetic thread can be applied to the respective application point.
[0045] As already explained above, a thread convergence point is understood to be a collection point for the plurality of synthetic threads from a thread curtain, so that the plurality of synthetic threads can be applied collectively at the associated application point. It should be noted that the collected plurality of synthetic threads form a converged thread curtain, in which individual threads can be arranged adjacent to one another. However, to arrange the converged thread curtain, it is necessary for the subsequent application processes to separate the converged thread curtain into a spaced-apart thread curtain, in which the individual threads are spaced apart from one another, with the spacing resulting from the distances between the individual winding positions.
[0046] According to one embodiment of the device, a thread convergence point is formed by means of and on the respective thread laying device by bringing the thread curtain together, wherein the brought together threads of the thread curtain are separated by means of a first and a second winding position laying device in winding positions for application to the winding spindle.
[0047] The gathering of the thread curtain at the thread convergence points simplifies the application to the individual application positions of the winding device and the subsequent separation to the winding positions enables the winding on the designated winding spindle.
[0048] According to one embodiment of the device, the respective thread laying device for forming the first to sixth thread convergence points is movable, stationary, on or near the winding device.
[0049] The type and type of laying device on the winding device varies depending on the function and task and can therefore be attached either directly to the winding device or at a certain distance so that the necessary movements of the automatic feeding device or laying device can also be carried out.
[0050] According to a further embodiment of the device, the thread laying device has a suction opening for forming a first or sixth convergence point, a positioning guide groove for forming a second thread convergence point, a positioning pivot arm for forming a third thread convergence point, a positioning attachment for forming a fourth thread convergence point and / or a positioning pendulum point for forming a fifth thread convergence point and a sliding feeder for applying the thread curtain to the winding device.
[0051] The thread application devices listed above can be provided at preferred application points depending on the design of the winding device.
[0052] However, the selection of thread application devices is not limited to the above-mentioned embodiments. Specialized application devices can also be provided that combine and / or further separate the functions of the individual application devices.
[0053] According to one embodiment of the device, the suction mouth is formed on a suction gun with a suction pipe, the application guide groove is formed by a guide part, the application pivot arm is formed by a support with a pivot element, the application attachment is formed by a guide part, and the application pendulum point is formed by a pivot arm pendulum with a application roller, wherein the sliding feeder has a application lever that can be moved transversely to the thread running direction.
[0054] According to the above-mentioned embodiments of the respective thread laying device, various mechanical application means can be provided which allow the application of the synthetic threads to the winding device with automatically controllable devices on the winding device.
[0055] According to the device for automatic application according to the invention, different means are used for the thread laying devices, so that these can also be retrofitted to existing application devices or winding devices.
[0056] According to a particular embodiment of the device, the first winding position transfer device has a guide rail and a plurality of feed rollers which can be moved along the guide rail to the associated winding positions which correspond to the winding positions on the winding spindle, wherein the first winding position transfer device is arranged opposite to the thread running direction above a traversing device.
[0057] According to a further embodiment of the device, the second winding position transfer device has a pivoting body which can be moved back and forth on the winding device at the winding spindle between a distribution position for distributing the threads and a positioning device for positioning the threads on the winding spindle, and has a thread guide rail with a plurality of movable thread guides which can be moved to the winding positions on the winding spindle, wherein the second winding position transfer device is arranged below a traversing device in the thread running direction.
[0058] With the two winding position transfer devices, it is possible to separate the combined threads above and below the traversing device into the individual winding positions so that they can be wound onto the winding tubes that are locked on the winding spindle.
[0059] According to a further embodiment of the device, the attachment points on the winding device for the thread curtain have a godet, a traversing device and a winding spindle with associated winding positions.
[0060] The landing points may also have other locations and / or components of the winding device.
[0061] The key positions on the winding device where the synthetic thread is to be applied are listed here. This can include a godet, or even a heated godet suitable for tempering the synthetic thread. However, new application points can be provided by new or additional components on the winding device, such as a second interlacing device on the godets, into which the synthetic thread is to be correctly inserted.
[0062] The traversing devices can be either wing traversing devices or belt-driven finger traversing devices. With wing traversing devices, the traversing is achieved by means of counter-rotating rotors, while with finger traversing devices, the traversing is achieved by means of a reciprocating thread guide driven by a belt.
[0063] The winding spindle can be mounted on a bobbin turret, allowing uninterrupted winding and / or doffing. This means that the bobbin turret has at least two winding spindles.
[0064] According to a further aspect of the invention, a system is provided for automatically applying a plurality of synthetic threads to a plurality of winding positions by means of automatically controllable application means on a winding device, comprising a device according to at least one of the embodiments described above, which is set up to carry out the method according to at least one of the method embodiments described above.
[0065] The method according to the invention and the associated device are explained in more detail below using some embodiments of the device according to the invention and the method according to the invention with reference to the attached figures.

[0073] In the figures, reference coordinate systems x, y, z are shown, which indicate the height direction z, the length direction x and the width direction y in the direction of the respective view.
[0074] Using the reference coordinate system x, y, z, the viewing direction should be defined and specified so that the respective views can be better understood.
[0075] Fig. 1 shows a schematic side view in the zx direction plane of a winding device 100 with the device for automatic application, hereinafter also called thread laying device 1, together with a melt extruder 400, or spinning beam with a spinning plate 401.
[0076] The melt extruder 400 may also be a melt injector device, wherein the melt is not extruded through a spinneret 401, but via injection nozzles directly to the winder device 100.
[0077] The melt extruder 400 delivers a plurality of synthetic threads in the form of a thread curtain V, which can be applied to the individual application positions A on the winding device 100 by means of the thread laying device 1 and can be separated at predetermined first and second winding positions 10.1 to 10.n above and below a winding spindle 140.
[0078] N is a placeholder for a natural number that specifies the number of winding positions with a natural number.
[0079] In the illustrated embodiment, there are five winding positions. Depending on the length of the winding spindle 140 and the specified winding device, the winding position can vary, with the number n of winding positions 10.1 to 10.n depending on the number n of winding tubes 160 that can be mounted on the winding spindle 140 and the associated number n of traversing devices 130.
[0080] The winding device 100, shown in Fig. 1, comprises a godet 8, a traversing device 130, a pressure roller 120, and a winding spindle 140, which is driven and rotatably mounted on a winding spindle turret 150. Generally, two godets 8 are required to draw off the synthetic thread curtain V.
[0081] In the view shown, the winding device 100 is shown in a fully applied state of the synthetic threads F, wherein the individual synthetic threads F.l, F.2 to Fn are applied to the associated winding positions 10.1, 10.2 to 10.n on the winding spindle 41.
[0082] According to the invention, the thread laying device 1 with its application means, which are identified in Fig. 1 with the reference symbol A, are responsible for the correct application, wherein the reference symbols A also indicate the important application positions of the synthetic thread curtain on the winding device 100.
[0083] For the automatic application of the thread curtain V to the winder device 100, there are the predetermined application positions A and the thread convergence points K1 to K6, wherein the thread convergence point K6 is shown in detail in Fig. 4. The thread convergence points K1 to K6 are movable and / or fixed locations at which the synthetic thread curtain V is preferably applied in a combined manner, so that subsequent application at the predetermined application positions A can be carried out automatically.
[0084] Automatic application is understood here as an independent application of the winding device 100 with the controllable application means A, without the need for a human operator or a kinematic robot to assist in the application.
[0085] The application of the thread curtain V can be carried out independently by the winding device 100 with its associated thread laying device 1.
[0086] As can be seen from Fig. 1, the winding device 100 has a godet carrier 190 on which a first and second godet 8 are provided.
[0087] With the help of the godets 8, the thread curtain can be drawn out of the melt extruder and guided to the winding spindle 140. In the illustrated embodiment, two godets 8 are provided in the winding device 100. Depending on the synthetic thread F to be drawn off, the type and number of godets on the winding device 100 can be designed differently.
[0088] For applying the thread curtain V to the godets 8, a feed roller 12 is provided which can be moved along a guide track so that the thread curtain V is inserted into a swirling device 14.
[0089] In the event of a thread break, a thread guide comb 6 with a thread break cutter is activated, which then cuts the thread curtain V so that further fed synthetic thread F can be removed via a thread break suction device 4.
[0090] The godet carrier 190 has some of the application means 30, 20, 18, 16, 8, 28 of the thread laying device 1, which are arranged, for example, at the thread convergence points K1 to K6. The thread convergence point K3 on the godet carrier 190 has a pivoting application arm 18, which can be pivoted toward the godet carrier 190 when the synthetic thread F is applied to the winding device 100, so that the thread curtain V can be applied to the thread application attachment 16, which defines the fourth thread convergence point K4 on the godet carrier 190.
[0091] To insert the thread curtain V into the thread guide comb 6, the thread curtain V is then inserted into the thread guide chamber groove of the thread guide comb 6 with the aid of a sliding feeder 2 (see also detail in Fig. 3.1), which is shown and described in more detail below with reference to Fig. 3.1.
[0092] In order to apply the synthetic thread curtain V to the traversing device 130 and to the winding spindle 140 in the associated winding positions 10.1 to 10.n, the thread sheet V is also separated at the previously shown thread convergence points K2, K1 and K6 via the first and second winding position laying devices 700, 800, wherein only the first winding position laying device 700 is visibly shown in Fig. 1.
[0093] The second winding position transfer device 800 is shown in Fig. 4. The separated synthetic threads Fl, F.2 to Fn are traversed with the aid of the associated traversing device 130, with a separate traversing device 130 being provided for each synthetic thread Fl to Fn. The traversing device 130 can be a birotor and / or a finger traversing device.
[0094] To form a winding package 240 or to apply the associated winding tube 160, which is locked on the winding spindle 140, a pressure roller 120 is additionally provided, which ensures that the traversed synthetic thread F.l to Fn is pressed at the winding position 10.1 to 10.n at the associated traversing position 130 and reliably traversed there. A winding spindle turret 150 and the traversing device 130 are drivably mounted in the machine frame 300, which forms a support device for the winding device 100. The winding spindle turret 150 allows rotation of the respective winding spindle 140 into a winding position for winding the threads F onto the rinsing tubes 160 and into a doffer position for removing the winding packages 260 with the winding tubes 160. In Fig. 1, the winding spindle with the empty winding tubes is in the doffer position and the winding tube with the winding packages is in the winding position.
[0095] Additionally, Fig. 1 shows a further application means 28, 30 of the thread laying device 100. This application means 28, 30 has and defines the thread convergence points K1, K5, and K6, which are necessary for application, in particular, to the winding spindle 140.
[0096] The yarn sheet V is first provided, applied and held in the yarn convergence point Kl, which is formed and defined by a suction opening 30 of a suction pipe 22.
[0097] With the aid of the application suction pipe 22, a negative pressure can be transmitted and / or generated so that the thread curtain V can be applied there for the first application step, which also includes the thread convergence point Kl.
[0098] The application suction pipe can be pivoted in the Y direction towards the winding spindle 140 for application over the thread convergence point 6, so that the second winding position laying device 800 (not shown here) can separate the filament curtain at the winding positions 10.1 to 10.n for the winding spindle 140.
[0099] In addition, the feed suction pipe 22 has a feed pendulum point 28 which can be moved back and forth in the X direction or in the longitudinal direction of the winding spindle 140 by means of a pivoting feeder.
[0100] Furthermore, Fig. 1 also shows the second thread convergence point K2, which forms a placement guide groove 20 into which the plurality of synthetic threads F of the thread curtain V can be inserted by means of the automatically pivoting suction opening 30. Fig. 2 shows a schematic widthwise side view of the winding device 100 of the automatic thread placement device 1 in the ZY plane in the X longitudinal direction.
[0101] This particularly shows the position of the first and second winding spindles 140 on the winding turret 150 with an already wound bobbin package 260. Furthermore, the thread path in the thread running direction R from the sliding feeder 2 to the bobbin package 250 can be derived in the widthwise side view.
[0102] In addition, the position of the thread break suction 4 and the thread guide comb 6 for the thread break cutter 6 can be seen in the width side view, as well as the arrangement of the godets 8 with the associated drives.
[0103] Furthermore, a part of the thread laying device in the form of the application attachment 16 and the application swivel arm 18 can be seen in the extended position.
[0104] In addition, the carrier of the first winding position laying device 700 can be seen, wherein the position of the application guide groove 20 is only indicated and is no longer used after application and during the winding process as shown in Fig. 2.
[0105] Furthermore, the suction port 30 with the feed suction pipe 22 can be seen, where, in addition to the feed on the winding spindle 140, the feed pendulum point 28 with the associated pivoting feeder 28 can be seen. The feed pendulum point 28 is formed on the pivoting feeder 26.
[0106] Fig. 3.1 shows the winding device 100 in a schematic sectional view together with the first winding device 700 after the thread curtain V has been applied to the godet carrier via the thread laying device, which has the individual application means such as the suction opening 30, which forms the first thread convergence point K1, the application guide groove 20, which forms the second convergence point K2, the application pivot arm 18, and the application attachment 16 with the associated sliding feeder 2. In Fig. 3.1, on the right in the X direction, on an enlarged scale and in a plan view in the ZY direction, a thread application means of the thread insertion direction with application guide groove 20, application pivot arm 18, application attachment 16 and sliding feeder 2 is shown in detail, wherein the thread application means with movable components are shown with a movement arrow in their respective direction of movement.
[0107] In the illustrated application position of Fig. 3.1, the thread curtain V is already inserted into the thread guide comb 6, which has been carried out step by step with the previously described thread laying devices 30, 20, 18, 16 and 2, wherein the thread curtain V has been applied step by step at the thread convergence points K1, K2, K3 and K4.
[0108] The synthetic threads F are now applied to the winding device 100 so that the thread curtain V can be inserted at the godets 8 and in the interlacing device 14, wherein subsequently a separation of the synthetic threads F is applied at the winding positions 10.1 to 10.n, which are predetermined by the traversing device 31.
[0109] In Fig. 3.1, the next application step via the application roller 12 is shown, so that after the thread curtain V has been inserted in the interlacing device 14, the synthetic threads F can be separated into Fl to Fn by means of the application rollers 170 of the first winding position laying device 700.
[0110] Furthermore, Fig. 3.1 shows the true position and orientation of the thread guide comb 6, with the thread curtain V or the individual synthetic threads F being inserted into the grooves of the thread guide comb.
[0111] The yarn guide comb shown on the godet support 190 is shown in a simplified manner for clarity, with its actual position being shown functionally and schematically in the following figures for better differentiation from the individual components. Fig. 3.2 shows the next insertion step into the interlacing device 14 on the godet support 190, with the insertion roller 12 having been moved beyond the position of the interlacing device 14, so that the filament curtain V has been inserted into the interlacing device 14.
[0112] As can also be seen from Fig. 3.2, the thread curtain V is applied to both godets 8 and is still inserted in the application guide groove 20 at the thread convergence point K2.
[0113] For the separation of the thread curtain V into the individual threads Fl to Fn, reference is now made to Fig. 3.3, wherein the thread curtain V has been guided out of the application guide groove 20 by means of the movable suction 30, this being accomplished with the aid of the application pendulum point 28.
[0114] The feed pendulum station 28 has been moved into a position by means of the pivoting feeder 26 so that the feed rollers 170, which are arranged offset from one another in the Y direction, can grasp the individual synthetic threads F.l to Fn and move them into the corresponding first winding positions 10.1 to 10.n. This separation is illustrated in Fig. 3.3.
[0115] Fig. 4 shows a schematic partial sectional view of the winding device 100 from Fig. 1 with the second winding position transfer device 800.
[0116] The second winding position transfer device 800 is pivotally arranged in the machine frame 300 and has a pivot support 110 which can be moved back and forth between the winding spindles 140 by means of an actuator, so that the thread guides 101 on the thread guide rail 99 can be pivoted towards the synthetic threads F.
[0117] Furthermore, Fig. 1 shows a part of the thread transfer device in the form of the suction port 30, which brings the thread together at the thread convergence points K1 and K6. Furthermore, Fig. 4 shows the winding spindle turret 150 and a winding spindle 140 with a bobbin package 240 provided for a doffer position.
[0118] In addition, Fig. 4 shows the winding spindle turret 160 and its associated direction of rotation as well as a winding tube 160 positioned for winding with synthetic threads F on a winding spindle 140 in the winding position.
[0119] Both the direction of rotation of the winding spindle 140 and the pressure roller 120 are shown with corresponding rotation arrows. Furthermore, the pivoting range of the suction opening 30 for positioning on the second winding position transfer device 800 is also shown.
[0120] Fig. 5 shows in different views the second winding position laying device 800 in a YX-plane top view together with application means 28, 30 of the thread laying device 1 in the sixth thread convergence point K6 in a ZX-plane view.
[0121] As can be seen from Fig. 4, the application pendulum point 28 provides the synthetic threads in such a way that they can be applied individually to the associated winding positions 10.1 to 10.n on the winding spindle 140 with the aid of the thread guides 101 of the second winding position transfer device 800.
[0122] With a corresponding pivoting of the pivoting support 110 of the second winding position transfer device 800 about the X-axis direction towards the winding spindle 140, the separated threads Fl to Fn can be applied to the winding tubes 160 releasably locked on the winding spindle.
[0123] The second winding position transfer device 800 shown here has a compressed air line 801 with an associated compressed air control 803, by means of which the thread guides 101 can be moved to the associated winding positions 10.1 to 10.n. The thread guides 101 are guided to the associated winding positions 10.1 to 10.n via the thread guide rail 99 using compressed air. Fig. 6 shows, in a schematic block diagram, the individual process steps for applying synthetic threads to the winding device 100 shown in Fig. 1.
[0124] In step S1, a thread curtain V made of a plurality of synthetic threads is provided between the sliding feeder 2 on the godet carrier 190 and at the godet 8 of the winding spindle 140.
[0125] This is evident from Fig. 1; thus, a synthetic melt is provided via the melt extruder 400 at the suction port 30 so that the formed thread curtain V can be applied. This application to the suction port 30 causes the formation of a first thread convergence point Kl in step S2, wherein the thread convergence point Kl is adjacent to the winding spindle 140, which is in a doffer position.
[0126] Thereafter, in step S3, the first thread convergence point K1 of the thread curtain V is displaced to a second thread convergence point k2, which is defined by the application guide groove 20, by pivoting the application suction pipe 22 towards the application guide groove 20 on the winder device 100. As a result, the thread curtain V is inserted into the application guide groove 20.
[0127] In step S4, the thread curtain V is further applied to the winding device 100 by means of a pivotable application pivot arm 18, which defines the third thread convergence point K3, to the application attachment 16, which defines the fourth thread convergence point K4.
[0128] Subsequently, in step S5, the thread curtain V is inserted into the thread guide comb 6 by means of the movable sliding feeder 2.
[0129] In step S6, the thread curtain V is applied to the godet 8 by means of the application roller 12. Subsequently, in step 7, the thread curtain V is separated into spaced threads F.l to Fn by means of the first winding position transfer device 700 into associated winding positions 10.1 to 10.n, which correspond to traversing devices 130 for traversing the synthetic threads Fl to Fn.
[0130] In step S8, the suction opening 30 is pivoted from the first thread convergence point K1 to the sixth thread convergence point K6 in order to place the thread curtain V in the second winding position laying device 800, so that in step S9 the thread curtain V can be separated by means of the second winding position laying device 800 via the thread guides 101 into the associated winding position 10.1 to 10.n on the winding spindle 140.
[0131] In step S10, the second winding position transfer device 800 is then used to position the winding tubes 106 at the associated winding positions 10.1 to 10.n by pivoting the pivot support 110 into the associated position adjacent to the winding tubes 160, so that the synthetic threads Fl to Fn are engaged by the winding tubes 160 and the associated engagement grooves in the winding tubes 160.
[0132] After engaging the winding tubes 160, the winding of the synthetic threads Fl to Fn begins on the winding positions 10.1 to 10.n of the winding tubes 160.
[0133] The threads F.1 to Fn are cut by the thread guides 106 below the winding spindle so that correct winding on the winding tube 160 can take place.
[0134] This would complete the automatic application process on the winding device 100, wherein the application was carried out fully automatically without the assistance of an operator.
[0135] The presented method and the associated device are advantageously used in a system, wherein in other embodiments the thread laying device can also be designed in a unified manner in some application means, in which additional guide rails and drives are provided, so that individual application means can also have several functions.
[0136] Furthermore, in an embodiment of the winder device 100 not shown here, a second intermingling device and / or a third and / or godet 8 can be arranged on the godet carrier 190, which, depending on the position, may require additional application means, which are designed according to the invention to form additional thread convergence points. These embodiments thus also fall within the scope of the following patent claims.
