Description

[0001] The present invention relates to a method for automatically placing a plurality of synthetic threads onto a winding device, as described in the preamble of claim 1, and to an apparatus for automatically placing a plurality of synthetic threads onto a winding device, as described in the preamble of claim 9, and to a system using the method and the apparatus.

[0002] It is generally known in the prior art to use corresponding distribution devices and / or robots to semi-automatically and / or automatically place the synthetic thread to be wound on a winding device with thread rollers, traverse devices and winding spindles so that it can be permanently wound into a winding package.

[0003] However, placement robots for this purpose are very expensive and are also prone to malfunction and slow compared to human operators, which can result in increased amounts of scrap being generated during the placement process.

[0004] Semi-automatic placement devices usually require the assistance of an operator; in particular, a first operator must be located at the top spinning nozzle or spinneret (from which the synthetic thread is extruded), and the latter must be thrown down to a second operator, who is in most cases located one or two layers below the spinneret and on a plane flush with the winding device, so that the second operator can receive the extruded synthetic thread.

[0005] Only then can the winding device be placed, in most cases with the aid of a so-called suction gun, which guides the synthetic thread into a waste container by the vacuum generated until the synthetic thread has been placed on the winding device for winding and / or drawing.

[0006] Semi-automated placement processes and those performed by kinematic placement robots are time-consuming and expensive, require at least two operators, and are prone to failure.

[0007] It is therefore an object of the present invention to provide a method for automatically placing a synthetic thread onto a winding device without requiring operator intervention.

[0008] The invention also aims at providing a device for automatically placing a synthetic thread onto a winding device, which device also works without the support of an operator, and an associated system combining the method and the device.

[0009] With regard to the method, this object is achieved according to the invention by the features of claim 1 .

[0010] With regard to the device, this object is achieved according to the invention by the device features specified in claim 9 .

[0011] With regard to the system, this object is achieved by a system having the features of claim 17 .

[0012] According to one aspect of the present invention, a method for automatically placing multiple synthetic threads onto a winding device is provided, wherein the winding device has a guide roller for drawing multiple synthetic threads from a melt extruder, a winding spindle for winding the multiple synthetic threads, and multiple winding positions.

[0013] The depositing is carried out at a depositing point from the godet to the spinning beam by means of an automatically controllable depositing device which defines the position of the thread convergence point at which the plurality of synthetic threads are drawn towards each other.

[0014] A melt extruder is understood in this context to be a spinning beam having a spinneret for extruding the synthetic melt, for example.

[0015] However, the melt extruder can also be an injection molding device having a corresponding spinneret from which the melt can be extruded or pressed by a corresponding extruder in order to produce the synthetic yarn therefrom.

[0016] The synthetic thread is drawn off via godet rollers towards a winding device and wound thereon onto a winding tube which is releasably locked to a rotating winding spindle.

[0017] A placement point in this context is understood to be a position on the winding device which is necessary for placing, conveying and feeding the synthetic thread to a corresponding traversing device and a winding spindle for winding the synthetic thread.

[0018] When supporting the depositing process, an automatically controllable depositing device arranged on the winding device allows the synthetic thread to be deposited on the corresponding thread rollers, traverse devices and / or winding spindles without the need for additional operating personnel or kinematically movable robots on the winding device.

[0019] The placement devices required for this purpose are arranged adjacent to or adjacent to the necessary positions on the winding device.

[0020] A thread convergence point is understood in this context to be a position on the winding device which specifies the convergence of a plurality of synthetic threads at a predetermined position.

[0021] For example, the thread convergence point can be the suction opening of a suction gun or also a placement guide groove on a winding device, which is designed in such a way that multiple synthetic threads from the thread curtain are combined to form a thread bundle. With the help of an associated placement device, the position of the suction opening is moved in an automatically controllable manner.

[0022] According to one design embodiment of the method, a plurality of synthetic threads are placed by converging at thread convergence points (which are located at different positions on the winding device) and singulated by a winding position placing device on the winding device.

[0023] The method according to the invention is peculiar in that, for the automated placement of a plurality of synthetic threads, the latter are brought together from a thread curtain at a predetermined thread convergence point and then singulated again into spaced apart threads for precise positioning at a predetermined winding position.

[0024] A synthetic thread in this context is understood to be a synthetic thread which is extruded from a plastic melt and has a plurality of filaments.

[0025] A plurality of synthetic threads or a thread curtain are understood to be a plurality or a plurality of synthetic threads, respectively. In the case of a thread curtain, the synthetic threads are spaced apart from one another.

[0026] According to a further embodiment of the method, the position of the thread convergence point is arranged at different positions on the winding device as a function of the corresponding placement point on the winding device. It should be noted that according to the predetermined placement point (e.g., winding position on the godet, traverse device and / or winding spindle), the thread convergence point is moved accordingly on the winding device and the thread curtain converges at the associated thread convergence point for the new placement position.

[0027] According to a further embodiment of the method, the thread convergence point is triggered by activating a corresponding automatically controllable placement device.

[0028] For example, the automatically controllable placement device is a movable pivot arm and / or placement roller, which can be moved or automatically moved via corresponding tracks and / or guides and / or pivot points to the envisaged thread convergence point, so that the synthetic thread can be correctly and accurately positioned in the associated position of the winding device.

[0029] According to a further embodiment of the method, before the plurality of synthetic threads are placed and distributed at the respective placement points, the end positions of the thread convergence points are moved. According to the invention, before the placement, the thread convergence points are collected. The thread convergence points are moved from a suction position close to the winding spindle in a direction opposite to the thread running direction upwards towards the guide roller, whereby the respective end positions of the movement are changed and these convergence positions are moved from the guide roller back to the winding spindle.

[0030] This is done solely by an automatic placement device on the winding device, without the need for an operator to intervene for this purpose. According to a design embodiment of the method, when the plurality of synthetic threads are collected at the respective thread convergence points, the gathered plurality of synthetic threads are spaced apart to form threads spaced apart from one another, depending on the associated winding position.

[0031] The collection at the point where the wires converge is used to simplify the placement of the wires on the various elements of the winding device. For example, when the wires are to be placed on a winding tube on a traversing device and / or a winding spindle, a plurality of wires need to be singulated.

[0032] This singulation is also carried out using correspondingly associated devices on the winding device, so that individual synthetic threads can also be placed at the associated winding positions.

[0033] According to a further embodiment of the method, the plurality of gathered synthetic threads are spaced apart above the traversing device, in a direction opposite to the running direction and / or below the traversing device, along the thread running direction, by placing the device at the first and / or second winding position.

[0034] Particularly at the associated winding position, a plurality of synthetic threads need to be spaced apart so that the synthetic threads can be wound onto an associated winding tube (which is arranged and releasably locked on the winding spindle).

[0035] For example, the winding position placement device can have a placement roller, which can be moved to the individual winding positions via rails, and / or have a corresponding yarn guide, which can be pivoted back and forth on a pivotably guided rail in the area of ​​the winding spindle and can also be moved accordingly towards the individual winding positions.

[0036] According to one design implementation of the method, the following steps are performed:

[0037] - providing a thread curtain of a plurality of synthetic threads between the winding spindle and the slip placement device at the godet;

[0038] - forming a first thread convergence point at the suction opening of the suction tube placed adjacent to the winding spindle;

[0039] - by pivoting the placement suction tube toward the placement guide groove on the winding device, the first thread convergence point of the thread curtain is moved to the second thread convergence point, thereby inserting the thread curtain into the placement guide groove;

[0040] - placing the thread curtain on the placement attachment (which defines the fourth thread convergence point) by means of a pivotable placement pivot arm (which defines the third thread convergence point);

[0041] - Insert the thread curtain into the guide wire comb through the movable slide placer;

[0042] - placing the thread curtain on the godet roller via a placing roller;

[0043] - singulating the thread curtain into spaced-apart threads by means of a first winding position placing device at an associated winding position corresponding to a traversing device for traversing the synthetic threads;

[0044] - pivoting the suction port from the first thread convergence point to the sixth thread convergence point to place the thread curtain in the second winding position placement device;

[0045] - singulating the thread curtain at the associated winding position on the winding spindle by means of a second winding position placement device;

[0046] - Placing the wire singulated by the second winding position placing device at the winding position on the winding spindle.

[0047] Through the above-mentioned placement steps, the wire curtain from the melt extruder can be automatically placed on the winding device without the intervention of an operator or a kinematic robot, whereby the placement devices required for this purpose are arranged and formed on the winding device, so that the wire curtain can be placed at each winding position completely automatically.

[0048] According to another aspect, in terms of the apparatus, an apparatus for automatically placing a plurality of synthetic threads onto a winding device having a godet for drawing the plurality of synthetic threads from a melt extruder and a winding spindle for winding the plurality of synthetic threads at a plurality of winding positions is provided.

[0049] According to the invention, at each placement point on the winding device an automatic thread placement device is provided, which defines a thread convergence point by means of which the synthetic thread can be placed at the respective placement point.

[0050] As already discussed above, a thread convergence point is understood to be a collecting point of a plurality of synthetic threads from the thread curtain, such that the plurality of synthetic threads can be deposited in a collected form at the associated depositing point.

[0051] It must be noted that the collected multiple synthetic threads form a converging thread curtain, wherein the individual threads can be arranged adjacent to each other. However, in order to arrange the converging thread curtain for further placement processes, it is necessary to singulate the converging thread curtain into spaced thread curtains, wherein the individual threads are spaced apart from each other, whereby the spacing is a result of the spacing of the individual winding positions.

[0052] According to one design embodiment of the device, a thread convergence point is formed by converging the thread curtain with the help of and at a corresponding thread arrangement device, wherein the converging threads of the thread curtain are singulated at the winding position for placement on the winding spindle with the help of a first and a second winding position placement device.

[0053] Collecting the thread curtain at the point where the threads converge simplifies placement at the respective placement position of the winding device, and subsequent singulation to the winding position enables winding on the winding spindle provided for this purpose.

[0054] According to one design embodiment of the device, the respective thread arrangement devices for forming the first to sixth thread convergence points are designed to be movable, fixed on and / or at the winding device.

[0055] Depending on the function and task, the kind and type of placement device on the winding device is designed differently and can therefore be attached either directly to the winding device or at a certain interval so that the necessary movements of the automatic placement device or the placement device can also be carried out.

[0056] According to a further design embodiment of the device, the wire arrangement device for forming the first or sixth wire convergence point has a suction port, the wire arrangement device for forming the second wire convergence point has a placement guide groove, the wire arrangement device for forming the third wire convergence point has a placement pivot arm, the wire arrangement device for forming the fourth wire convergence point has a placement additional piece, and / or the wire arrangement device for forming the fifth wire convergence point has a placement swing point, and the wire arrangement device for placing the wire curtain on the winding device has a sliding placer.

[0057] Depending on the design embodiment of the winding device, the wire arrangement devices listed above can be arranged at preferred placement points.

[0058] However, the selection of the wire placement device is not limited to the above-mentioned embodiments. A dedicated placement device can also be provided, which combines the functions of individual placement devices and / or performs further singulation.

[0059] According to one design embodiment of the device, the suction opening is formed by a suction gun having a placement suction tube, the placement guide groove is formed by a guide component, the placement pivot arm is formed by a support having a pivot element, the placement attachment is formed by the guide component, and the placement swing point is formed by a pivotable swing arm having a placement roller, wherein the sliding placement device has a placement rod that can be moved transversely to the direction of wire running.

[0060] According to the above-described design embodiments of the corresponding thread arrangement device, various mechanical placement devices can be provided, which allow the synthetic thread to be placed on the winding device by means of an automatically controllable device on the winding device.

[0061] The device for automatic placement according to the invention uses different devices for the wire arrangement device, so that the latter can also be retrofitted to existing placement devices or winding devices.

[0062] According to a specific design embodiment of the device, the first winding position placing device has a guide rail and a plurality of placing rollers, which can be moved along the guide rail to an associated winding position, which corresponds to the winding position on the winding spindle, wherein the first winding position placing device is arranged above the traversing device (opposite to the direction of wire running).

[0063] According to a further design implementation of the device, the second winding position placement device has a pivot support, which can be reciprocated between a distribution position for distributing the wire and a placement position for placing the wire on the winding spindle at the winding device, and has a wire guide rail, which has a plurality of movable wire guides, which can be moved to the winding position on the winding spindle, wherein the second winding position placement device is arranged below the traverse device (along the wire running direction).

[0064] By means of two winding position placement devices above and below the traversing device, the gathered threads can be singulated to the individual winding positions so that they can be wound onto a winding tube locked on the winding spindle.

[0065] According to a further embodiment of the device, the placement point of the thread curtain on the winding device has a godet roller, a traversing device and a winding spindle with an associated winding position.

[0066] The placement point can also have other points and / or components of the winding device.

[0067] The main locations of the winding device where the synthetic yarn is to be placed are mentioned here. These may include godets, even heated godets, which are suitable for temperature control of the synthetic yarn. However, new placement points may be provided on the winding device by new or additional components (e.g. a second entanglement device at the godet), into which the synthetic yarn needs to be correctly inserted.

[0068] The traversing device can have a vane traverser and / or a belt-driven finger traverser. In the case of a vane traverser, the traversing is performed by counter-rotating rotors, while in the case of a finger traverser, the traversing is performed by a thread guide that can be moved back and forth by means of a belt.

[0069] The winding spindles can be arranged on the winding turret so that winding and / or doffing can be carried out uninterruptedly. This means that the winding turret has at least two winding spindles.

[0070] According to a further aspect of the present invention, a system is provided for automatically placing multiple synthetic threads at multiple winding positions by an automatically controllable placement device on a winding device, the system having an apparatus according to at least one of the above-mentioned design embodiments, and the apparatus is designated to perform a method according to at least one of the above-mentioned method design embodiments.

[0071] The method according to the invention and the associated device will be explained in more detail below with the aid of a few exemplary embodiments of the device according to the invention and the method according to the invention and with reference to the accompanying drawings.

[0080] Figure 6 Shown is the Figure 1 A schematic block diagram of the various placement steps of a method for automatically placing multiple synthetic silk threads on a winding device.

[0081] In each of the drawings, reference coordinate systems x, y, z are shown, indicating the vertical direction z, the longitudinal direction x, and the width direction y in the corresponding viewing direction, respectively.

[0082] Each view direction is defined and indicated with the help of a reference coordinate system x, y, z for better understanding of each view.

[0083] Figure 1A winding device 100 with a device for automatic placement (also referred to below as thread placement device 1 ) is shown in a schematic side view in the zx plane, together with a melt extruder 400 or a spinning beam with a spinneret 401 .

[0084] The melt extruder 400 may also be a melt injection device, in which the melt is not extruded through a spinneret 401 but is directly extruded to the winding device 100 through an injection nozzle.

[0085] The melt extruder 400 releases a plurality of synthetic threads in the form of a thread curtain V which is placed at various placement positions A on the winding device 100 by means of the thread arrangement device 1 and can be singulated at predetermined first and second winding positions 10 . 1 to 10 . n above and below the winding spindle 140 .

[0086] Here, N is a placeholder for a natural number indicating the number of winding positions using a natural number.

[0087] In the exemplary embodiment shown, there are five winding positions. Depending on the length of the winding spindle 140 and the predefined winding device, the winding positions can vary, wherein the number n of winding positions 10.1 to 10.n is a function of the number n of winding tubes 160 that can be attached to the winding spindle 140 and of the number n of associated traversing devices 130.

[0088] Figure 1 The winding device 100 shown in FIG. 1 has a godet 8, a traverse device 130, a contact pressure roller 120 and a winding spindle 140 which is rotatably arranged so as to be driven on a winding spindle turret 150. Typically, two godet rollers 8 are required to draw off a synthetic thread curtain V.

[0089] In the illustrated view, the winding device 100 is in a fully laid state of the synthetic thread F, whereby the individual synthetic threads F.1 , F.2 to Fn are laid at the associated winding position 10 . 1 , 10 . 2 to 10 . n on the winding spindle 41 .

[0090] According to the present invention, the placing device (in Figure 1 The thread arrangement device 1 (indicated by reference numeral A in the figure) is responsible for the correct placement, wherein reference numeral A also indicates the important placement position of the synthetic thread curtain on the winding device 100.

[0091] The predefined placement positions A and thread convergence points K1 to K6 are used to automatically place the thread curtain V on the winding device 100, whereby the thread convergence point K6 is located at Figure 4 Shown in detail.

[0092] The thread convergence points K1 to K6 are movable and / or fixed points at which the synthetic thread curtain V is preferably placed in a gathered form in order to be able to be placed automatically at a predetermined placement position A subsequently.

[0093] In this context, automatic placement is understood to mean independent placement of the winding device 100 by means of the controllable placement device A, without the need for assistance during placement by an operator or a kinematic robot.

[0094] The laying of the thread curtain V can be carried out independently by means of the winding device 100 with the aid of its associated thread arranging device 1 .

[0095] from Figure 1 It can be seen that the winding device 100 has a godet support 190 on which the first and second godets 8 are arranged.

[0096] With the aid of godet rollers 8, a thread curtain can be drawn from the melt extruder and fed to the winding spindle 140. In the exemplary embodiment shown, two godet rollers 8 are provided in the winding device 100. Depending on the synthetic thread F to be drawn, the type and number of godet rollers on the winding device 100 can be designed differently.

[0097] In order to place the thread curtain V at the godet roller 8 , a placing roller 12 is provided which is movable along a guide rail so that the thread curtain V can be inserted into the entanglement device 14 .

[0098] In the event of a thread breakage, the thread guide comb 6 with the thread breakage cutter is activated, which then cuts the thread curtain V so that the synthetic thread F that continues to be fed can be discharged through the thread breakage suction unit 4 .

[0099] The godet support 190 has some depositing devices 30 , 20 , 18 , 16 , 8 , 28 of the thread depositing device 1 , which are arranged, for example, at the thread converging points K1 to K6 .

[0100] The thread convergence point K3 on the guide roller support 190 has a placement pivot arm 18, which can be pivoted toward the guide roller support 190 when the synthetic thread F is placed on the winding device 100, so that the thread curtain V can be placed at the placement attachment 16 that defines the fourth thread convergence point K4 on the guide roller support 190.

[0101] In order to insert the thread curtain V into the guide wire comb 6, the sliding placement device 2 (see also Figure 3.1 The details in the figure) insert the wire curtain V into the wire guide comb groove of the wire guide comb 6, which will be referred to below Figure 3.1 shown and described in more detail.

[0102] In order to place the synthetic thread curtain V in the associated winding positions 10.1 to 10.n on the traversing device 130 and the winding spindle 140, the thread curtain V is singulated at the previously shown thread convergence points K2, K1 and K6 by means of the first and second winding position placing devices 700, 800, thereby Figure 1 Only the first winding position placement device 700 is visibly shown.

[0103] The second winding position placement device 800 is shown in Figure 4 The traversing of the individualized synthetic threads F.1, F.2 to Fn is performed by means of associated traversing devices 130, whereby a dedicated traversing device 130 is provided for each synthetic thread F.1 to Fn. The traversing device 130 can be a double rotor and / or a finger-shaped traversing device.

[0104] In order to form the winding bobbin 240, or to place the associated winding tube 160 locked on the winding spindle 140, a contact pressure roller 120 is also provided, which ensures that the traversing synthetic thread F.1 to Fn is pressed against the winding position 10.1 to 10.n at the associated traversing position 130 and is reliably traversed thereon.

[0105] The winding spindle turret 150 and the traverse device 130 are held so as to be drivable in a frame 300 constituting a support device of the winding device 100. The winding spindle turret 150 allows the corresponding winding spindle 140 to be rotated to a winding position for winding the thread F onto the winding tube 160 and to a doffing position for removing the winding bobbin 260 together with the winding tube 160. Figure 1 In the embodiment of the present invention, the winding spindle with the empty winding tube is in the doffing position and the winding tube with the winding bobbin is in the winding position.

[0106] Figure 1 1 and 2 , further placement devices 28 , 30 of the thread arrangement device 100 are also shown. The placement devices 28 , 30 have and define thread convergence points K1 , K5 and K6 which are necessary in particular for placement on the winding spindle 140 .

[0107] The thread curtain V is first provided at the thread convergence point K1 which is formed and defined by the suction port 30 in which the suction tube 22 is placed, and is placed and held therein.

[0108] A vacuum can be transferred and / or generated by means of the placement suction tube 22 so that the thread curtain V can be placed there for the first placement step, the latter also comprising the thread convergence point K1 .

[0109] For placement, the placement suction tube can be pivoted in the y direction toward the winding spindle 140 over the thread convergence point 6, so that the second winding position placement device 800 (not shown here) can singulate the filament curtain at the winding positions 10.1 to 10.n of the winding spindle 140 at the thread convergence point K6.

[0110] Furthermore, the depositing suction tube 22 has a depositing pivot 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 depositor.

[0111] also, Figure 1 Also shown is a second thread convergence point K2 which forms a placement guide groove 20 into which a thread curtain V of a plurality of synthetic threads F can be inserted by means of an automatically pivotable suction opening 30 .

[0112] Figure 2 2 shows a schematic widthwise side view of the automatic wire placement device 1 of the winding apparatus 100 in the x-longitudinal direction in the zy plane.

[0113] In particular, the position of the first and second winding spindles 140 on the winding turret 150 can be seen, which have already wound bobbins 260. In addition, the direction of the wire in the wire running direction R from the sliding placement device 2 towards the winding bobbins 250 can be seen in the width direction side view.

[0114] Furthermore, the position of the wire suction unit 4 and the guide comb 6 for the wire cutter 6 can be seen in the widthwise side view, as well as the arrangement of the wire godet 8 and its associated drive.

[0115] Furthermore, part of the thread deployment device can be seen in the form of a deployment attachment 16 and a deployment pivot arm 18 in the deployed position.

[0116] Furthermore, the support of the first winding position placement device 700 can be seen, wherein only the position of the placement guide groove 20 can be inferred, which is used during placement and in the following manner. Figure 2 The winding process shown is no longer used.

[0117] Furthermore, the suction opening 30 with the suction tube 22 for placement can be seen, on which the placement pivot point 28 with the associated pivoting placement device 28 for placement on the winding spindle 140 can additionally be seen. The placement pivot point 28 is formed on the pivoting placement device 26.

[0118] Figure 3.1A schematic sectional view of the winding device 100 is shown together with a first winding position placement device 700, at which time the wire curtain V has been placed on a wire roller support by a wire arrangement device, the wire roller support having various placement devices, such as a suction port 30 (forming a first wire convergence point K1), a placement guide groove 20 (forming a second convergence point K2), a placement pivot arm 18 and a placement attachment 16 and an associated sliding placer 2.

[0119] Figure 3.1 In the figure, on the right side along the x direction and in the top view along the zy direction, a wire placing device of the wire arrangement device is shown in detail on an enlarged scale, which has a placing guide groove 20, a placing pivot arm 18, a placing attachment 16 and a sliding placer 2, wherein the wire placing device with movable parts is shown with arrows indicating their respective movement directions.

[0120] exist Figure 3.1 In the placement position shown, the thread curtain V has been inserted into the guide wire comb 6, which is carried out step by step by the above-mentioned thread arrangement devices 30, 20, 18, 16 and 2, wherein the thread curtain V has been placed step by step at the thread convergence points K1, K2, K3 and K4 in each case.

[0121] The synthetic thread F has now been placed on the winding device 100 so that the thread curtain V can be inserted onto the godet 8 and into the entanglement device 14 , wherein after singulation the synthetic thread F is placed at the winding positions 10 . 1 to 10 . n predetermined by the traversing device 31 .

[0122] Figure 3.1 , the next placement step by means of the placement roller 12 is shown so that after the wire curtain V has been inserted into the entanglement device 14, the synthetic thread F can be singulated into F.1 to Fn by means of the placement roller 170 of the first winding position placement device 700.

[0123] also, Figure 3.1 The actual position and orientation of the guide wire comb 6 is shown in FIG. , wherein the thread curtain V or the individual synthetic threads F are inserted into the grooves of the guide wire comb.

[0124] For a better understanding, the godet comb shown on the godet roller support 190 is shown in a simplified representation, whereby its actual position in the following figures is represented functionally and schematically in order to better distinguish the individual components.

[0125] Figure 3.2 , the next placement step into the entanglement device 14 is shown on the godet roller support 190, whereby the placement roller 12 has been moved to a position beyond the entanglement device 14, so that the filament curtain V has been inserted into the entanglement device 14.

[0126] Also from Figure 3.2It can be seen that the thread curtain V is placed on two godet rollers 8 and is still inserted in the placement guide groove 20 at the thread convergence point K2.

[0127] Regarding the singulation of the cord V into individual threads F.1 to Fn, refer to Figure 3.3 , whereby the wire curtain V has been drawn out of the placement guide groove 20 by means of the movable suction unit 30 , which is done by means of the placement swing point 28 .

[0128] The depositing oscillation point 28 has been moved by means of the pivoting depositor 26 to a position such that the depositing rollers 170 arranged offset from one another in the y direction can pick up the individual synthetic threads F.1 to Fn and move the latter into the associated first winding position 10.1 to 10.n. This singulation is shown in Figure 3.3 middle.

[0129] Figure 4 Shows Figure 1 A schematic partial cross-sectional view of a winding device 100 having a second winding position placement device 800.

[0130] The second winding position placement device 800 is pivotably arranged in the frame 300 and has a pivot support 110, which can be reciprocated between the winding spindles 140 by means of an actuator so that the wire guide 101 on the wire guide rail 99 can be pivoted toward the synthetic wire F.

[0131] also, Figure 1 1 and 2. A portion of the wire arrangement device is shown in FIG. 2 in the form of a suction port 30 which converges the wire bundles at the wire convergence points K1 and K6.

[0132] also, Figure 4 2 shows a winding spindle turret 150 and a winding spindle 140 which has a winding bobbin 240 and is arranged for a doffing position.

[0133] also, Figure 4 , a winding spindle turret 160 and its associated direction of rotation as well as a winding tube 160 are shown, which is positioned to be wound with a synthetic thread F and is in a winding position on the winding spindle 140.

[0134] The direction of rotation of the winding spindle 140 and the contact pressure roller 120 is indicated by the corresponding rotation arrows. In addition, the pivoting range of the suction opening 30 for placement on the second winding position placement device 800 is also shown.

[0135] Figure 5The second winding position placement device 800 is shown in different views in a top view in the yx plane together with the placement devices 28 , 30 of the thread arrangement device 1 at the sixth thread convergence point K6 in a view in the zx plane.

[0136] from Figure 4 It can be seen that the placement oscillation point 28 provides the synthetic thread in such a way that the latter can be placed in a singulated form at the associated winding position 10 . 1 to 10 . n on the winding spindle 140 by means of the thread guide 101 of the second winding position placement device 800 .

[0137] When the pivot support 110 of the second winding position placement device 800 is pivoted about the x-axis direction respectively towards the winding spindle 140, the singulated wires F.1 to Fn can be placed on the winding tube 160 which is releasably locked on the winding spindle.

[0138] The second winding position placement device 800 shown here has a compressed air line 801 with an associated compressed air controller 803, by means of which the yarn guide 101 can be moved to the associated winding position 10.1 to 10.n. The yarn guide 101 is guided to the associated winding position 10.1 to 10.n by compressed air via the yarn guide rail 99.

[0139] Figure 6 A schematic block diagram is shown for Figure 1 The various method steps for placing a synthetic thread on a winding device 100 are shown.

[0140] In step S1 , a thread curtain V of a plurality of synthetic threads is provided between the slip placement device 2 at the godet 8 at the winding spindle 140 and the godet support 190 .

[0141] This can be obtained from Figure 1 In this way, the synthetic melt is provided at the suction port 30 via the melt extruder 400 so that the formed wire curtain V can be placed. This placement at the suction port 30 requires forming a first wire convergence point K1 in step S2, wherein the wire convergence point K1 is adjacent to the winding spindle 140, which is in the doffing position.

[0142] Thereafter, in step S3, the first thread convergence point K1 of the wire curtain V is moved to the second thread convergence point K2 (the latter being defined by the placement guide groove 20) by pivoting the placement suction pipe 22 toward the placement guide groove 20 on the winding device 100. As a result, the wire curtain V is inserted into the placement guide groove 20.

[0143] In step S4 , the thread curtain V is further placed on the winding device 100 by placing on the placing attachment 16 , which defines the fourth thread convergence point K4 , with the aid of the pivotable placing pivot arm 18 , which defines the third thread convergence point K3 .

[0144] Subsequently, in step S5 , the thread curtain V is inserted into the guide wire comb 6 by means of the movable slide placement device 2 .

[0145] In step S6 , the thread curtain V is placed on the godet roller 8 by means of the placing roller 12 .

[0146] Thereafter, in step S7, singulation of the thread curtain V into spaced apart threads F.1 to Fn is performed by means of the first winding position placing device 700 in the associated winding positions 10.1 to 10.n corresponding to the traversing device 130 for traversing the synthetic threads F.1 to Fn.

[0147] In step S8, the suction port 30 is pivoted from the first thread convergence point K1 to the sixth thread convergence point K6 to place the thread curtain V in the second winding position placement device 800, so that in step S9, the thread curtain V can be singulated in the associated winding positions 10.1 to 10.n on the winding spindle 140 by means of the second winding position placement device 800 through the thread guide 101.

[0148] In step S10, the synthetic threads F.1 to Fn are then placed at the associated winding positions 10.1 to 10.n on the winding tube 106 by the second winding position placement device 800, by pivoting the pivot support 110 to the associated position adjacent to the winding tube 160, so that the synthetic threads F.1 to Fn engage with the winding tube 160 and the associated engagement grooves in the winding tube 160.

[0149] When engaging the winding tube 160 , the synthetic threads F. 1 to Fn begin to be wound at the winding positions 10 . 1 to 10 . n of the winding tube 160 .

[0150] The threads F. 1 to Fn are cut below the winding spindle by the thread guide 106 so that they can be wound correctly onto the winding tube 160 .

[0151] Thus, the automatic placement process on the winding device 100 is terminated, wherein the placement has been carried out fully automatically without the assistance of an operator.

[0152] The proposed method and the associated device are advantageously used in systems, wherein in other exemplary embodiments the wire placement device can also be embodied in a standard manner in some placement devices by providing additional guides and drives so that a single placement device can also perform multiple functions.

[0153] Furthermore, in exemplary embodiments of the winding device 100, which are not shown here, a second entanglement device and / or a third and / or a godet 8 can be arranged on the godet support 190, which, depending on the location, may require additional placement devices, which according to the invention are designed to form additional thread convergence points. Therefore, these exemplary embodiments are also within the scope of protection of the following patent claims.
