Description

Technical Field

[0001] The present invention relates to an auxiliary splicing device for splicing a plurality of synthetic filaments, a related auxiliary splicing method, and a winding device having the auxiliary splicing device and / or the auxiliary splicing method. Background Art

[0002] Winding devices are known from the general prior art, which have means for distributing synthetic filaments in the associated winding device.

[0003] DE10347783A1 discloses a winding device for winding a plurality of filaments to form a bobbin and a method for initially splicing a filament group in such a winding device. For winding the filaments onto a plurality of bobbins fixed to rotatably mounted bobbin spindles, there is provided a stationary distributing device for positioning the filaments from a respective collection position into the splicing positions assigned to the bobbins, and there is provided a movable splicing mechanism for deflecting the filaments into the picking position. Here, the distributing device and the splicing mechanism interact with a suction device for initially splicing and picking up the filaments. In order to obtain as gentle a filament guidance as possible, after distributing the filaments to the respective splicing positions assigned to the bobbins, the filaments are transferred from the distributing device to the splicing mechanism that deflects the filaments into the picking position.

[0004] DE102005005129B4 discloses and claims a device for winding a plurality of filament groups, which has two winding devices arranged adjacent to each other in a mirror-inverted manner, each winding device having a winding turntable with two rotatably mounted bobbin spindles projecting therefrom, and each winding spindle winding a filament group to form a bobbin, wherein the winding turntable and the bobbin spindles can be driven and controlled independently of each other by associated drive means and a controller, and wherein auxiliary means are arranged between the winding devices, by means of which filament splicing and / or bobbin changing can be carried out on both winding devices, and the auxiliary means can be controlled by the controller of one of the winding devices. The auxiliary means has a number of movable guiding mechanisms associated with the winding devices, wherein the guiding mechanisms can be guided together by associated drive means, and the guiding mechanisms are formed by two push-off forks assigned to the winding devices for pushing off full bobbins.

[0005] In the case of an auxiliary splicer for splicing synthetic filaments in a winding device, it is particularly problematic that the splicing of a filament group or a plurality of synthetic filaments on a bobbin spindle can be difficult and complex to implement. This is particularly complex, especially in the case of mirror-symmetrically arranged winding devices, because the splicing area on the bobbin spindle is additionally obscured by the mirror-symmetrically arranged winding devices. Summary of the Invention

[0006] Accordingly, an object of the present invention is to provide an auxiliary splicing device for splicing a plurality of synthetic filaments, a related auxiliary splicing method, and a winding device, by means of which the above problems can be avoided or at least reduced.

[0007] According to the present invention, with regard to the auxiliary splicing device, this object is achieved by an auxiliary splicing device.

[0008] According to one aspect of the present invention, there is provided an auxiliary splicing device for splicing a plurality of synthetic filaments in a plurality of creel positions in a traverse device of a winding device, the auxiliary splicing device having a first distribution device for distributing a plurality of filaments in a plurality of traverse positions above the traverse device in the filament running direction and a second distribution device for distributing a plurality of filaments in a plurality of creel positions below the traverse device in the filament running direction, wherein a converging splicing device configured to form a converging point is located below the second distribution device, and wherein the converging point can be positioned three-dimensionally relative to the winding device by means of the converging splicing device.

[0009] With the auxiliary splicing device, a plurality of synthetic filaments can be spliced semi-automatically and / or automatically in the relevant traverse positions and creel positions by means of the converging splicing device. This is particularly advantageous in the case where the winding device has two bobbins, namely a right winding machine and a left winding machine, which are combined in such a way that it is particularly difficult and complex for an operator to perform splicing on the second distribution device.

[0010] Herein, the converging splicing device particularly helps to achieve a more reliable and less complex filament splicing in the creel positions on the second distribution device by means of the converging splicing device having a three-dimensionally positionable converging point, so that the converging point can always be adjusted or positioned in the respective positions to move the synthetic filaments to the respective positions, and as a result, splicing can be performed in the creel positions predetermined by the second distribution device.

[0011] According to a further improvement of the auxiliary splicing device, the converging point can be moved by means of the converging splicing device to a parking position for parking the converging splicing device on the winding device, a tilting position for tilting the converging splicing device away from the winding device, and a splicing position for splicing a plurality of synthetic filaments to the second distribution device.

[0012] Due to the fact that the converging splicing device can be positioned and moved three-dimensionally, the converging splicing device and / or the converging point related to the splicing of the synthetic filaments can occupy different positions relative to the winding device, in particular the second distribution device.

[0013] For example, the converging joint device can be moved to a parked position. In the parked position, the converging joint device can be positioned on the winding device such that its components can be moved and pivoted together, so that the operation of the winding device can proceed smoothly without collision with the moving components of the winding device.

[0014] For example, a winding spool must be removed from or doffed on the winding device.

[0015] This can be done in an uncomplicated and unobstructed manner by the converging joint device in the parked position.

[0016] In addition, the winding device or its controller is configured such that the operation of the winding device and the associated winding of the synthetic filament can form a winding spool only when the converging joint device is in the parked position.

[0017] In order for the joints and the design to converge and collect all the synthetic filaments at a converging point, the converging joint device needs to be moved to a tilted position. In the tilted position, the converging joint device tilts away from the winding device to a predetermined angle and extent. The tilt angle can be from 20° to 50°, depending on how far the converging joint device needs to tilt to produce convergence.

[0018] In the joint position, the converging point is pivoted to the joint position. As a result, the synthetic filaments to be joined and merged at the converging point form a fan shape. As a result, the second dispensing device and its thread grippers can each grip a filament from the filament fan to join it to the bobbin position.

[0019] According to another improvement of the auxiliary joint device, the converging joint device has a guiding mechanism for pivoting the converging point from the parked position to the joint position and a tilting mechanism for tilting the converging joint device to the tilted position, wherein pivoting the converging point to the joint position can be carried out before, during and / or after tilting of the converging joint device.

[0020] The guiding mechanism and the tilting mechanism are arranged to guide the converging point to the respective desired positions.

[0021] The guiding mechanism has substantially interconnected struts by means of which the converging point can be precisely guided to the desired position.

[0022] In addition, the converging joint device has a tilting mechanism for a further degree of freedom of movement, by means of which the converging joint device can be tilted to a predetermined tilted position, wherein the tilt angle is also of variable design, so that the optimal tilt angle for joining the filaments at the converging point can always be achieved.

[0023] In extreme cases, this tilt angle can be from 0° to 90°.

[0024] In particular, a tilting angle of 90° may be suitable, for example, for the maintenance of the converging joint device.

[0025] The tilting mechanism has a rotating shaft for tilting purposes and a bottom plate and a pivot plate that are hingedly connected to the pivot, and as a result, the tilting of the entire converging joint device can be achieved without complication.

[0026] In another improvement of the exemplary joint device, the guiding mechanism and / or the tilting mechanism have drive means that can be automatically open-loop and / or closed-loop controlled, wherein the guiding mechanism can be configured to pivot the converging point at a pivoting angle in the range of 0° to 45°, in particular 0° to 89°, and wherein the tilting mechanism can be configured to tilt the converging joint device at a tilting angle in the range of 0° to 50°, in particular 0° to 90°.

[0027] Depending on the given application, the guiding mechanism and / or the tilting mechanism may have dedicated or shared drive means, and as a result, their respective positions can be automatically actuated during the joint operation by the controller of the winding device.

[0028] The controller can accomplish this through a pure control operation, where it remains in its respective position within a predetermined time, and / or this can be monitored in combination with sensors, and as a result, a closed-loop control operation can be achieved so that it occupies its respective position only when the sensors detect the corresponding positions of the converging joint device and / or the winding device.

[0029] Furthermore, both the guiding mechanism and the tilting mechanism are configured such that the converging joint device itself and / or the associated converging point can occupy a predetermined pivoting angle and / or tilting angle.

[0030] The respective angles can range from 0° to 45°, from 0° to 90°, and intermediate angles within their respective ranges are also possible, and as a result, the converging joint device can always be set in an optimal manner and the joint process can be adjusted according to individual cases.

[0031] According to another improvement of the auxiliary joint device, the guiding mechanism has a pivoting arm on which a first mechanism support and a second mechanism support having a converging point assembly can be pivotally mounted on a mechanism coupled to a drive means, such that the pivoting arm can pivot from a parked position to a joint position and back.

[0032] The guiding mechanism has a main pivoting arm, and the mechanism supports for guiding the converging point are mounted on the main pivoting arm, and these mechanism supports are connected to a mechanism coupler such that during the pivoting to the parked position and the joint position, the pivoting arm moves the converging point to a predetermined joint position.

[0033] According to another improvement of the auxiliary joint device, the guiding mechanism and / or the tilting mechanism have monitoring sensors for monitoring the current position of the guiding mechanism and / or the tilting mechanism.

[0034] The position of the guiding mechanism and / or the tilting mechanism can be monitored and / or closed-loop controlled by monitoring sensors.

[0035] In this way, the optimal position of the guide mechanism and the tilting mechanism can always be reported to the winding device controller. In addition, if the guide mechanism and the tilting mechanism can communicate with the relevant drive device accordingly and the data of the relevant monitoring sensors are transmitted to the controller of the guide mechanism and the tilting mechanism in an evaluable manner to control its position in a closed loop, a corresponding closed-loop control operation can also be achieved.

[0036] According to the auxiliary joint method, the object is achieved by an auxiliary joint method.

[0037] According to one aspect of the invention, there is provided an auxiliary piecing method for piecing a plurality of synthetic threads in a plurality of traverse positions in a traverse device of a winding device, in particular using an auxiliary piecing device according to at least one of the aforementioned improvements, wherein the auxiliary piecing method comprises the following steps:

[0038] - distributing the plurality of synthetic threads at the plurality of traversing positions by means of a first distributing device,

[0039] -tilt the convergent joint device to the tilted position,

[0040] - inserting the plurality of synthetic threads into the convergence point,

[0041] -tilt the junction device to the parking position,

[0042] -pivoting the pivot arm to the joint position,

[0043] - distributing the plurality of threads to the plurality of winding positions by means of a second distribution device,

[0044] - the convergent joint device is tilted to the tilted position along with the pivoting arm,

[0045] -Turn the winding spindle to the winding position,

[0046] - by means of a second distribution device, multiple threads are connected to multiple winding positions on the winding spindle,

[0047] -Tilt the junction device and pivot the pivot arm back to the parking position.

[0048] The auxiliary piecing method allows for a simple piecing of the synthetic yarn at the traverse position and the winding position without the operator having to intervene in the auxiliary piecing method, especially when piecing to the winding position. This is particularly advantageous if the piecing area is concealed in the winding position by the second winding device or another component, such as a wall. ​​

[0049] This ensures that a reliable joint of the synthetic filaments is possible, even if the position close to the winding bobbin is restricted or hidden, especially in the direction of extension of the winding device.

[0050] The rotation of the winding bobbin to the winding position especially means that the winding bobbin is rotated to the winding state by the winding turntable.

[0051] According to a further improvement of the auxiliary joint method, the pivot arm is pivoted after the distribution of a plurality of filaments to a plurality of winding positions by the second distribution device.

[0052] The auxiliary joint method can also be designed such that an additional movement of the converging joint device is possible in order to also be able to carry out the necessary movements that may be required during these method steps.

[0053] According to a further improvement of the auxiliary joint method, the pivot arm is pivoted to its parked position before the converging joint device is tilted back to the parked position.

[0054] This may be necessary in order not to carry along nearby objects or operators when the converging joint device tilts backward during the joint operation on the winding device.

[0055] If an object or an operator is in the pivoting area of the pivot arm, this measure can also be triggered by a corresponding sensor to avoid accidents.

[0056] Regarding the winding device, this object is achieved by a winding device.

[0057] According to one aspect of the present invention, there is provided a winding device for winding a plurality of synthetic filaments, having a first distribution device and a second distribution device and a winding turntable for rotating a first winding bobbin and a second winding bobbin to the winding position and the doffing position, wherein the joining of the synthetic filaments to the respective winding bobbins can be carried out by means of an auxiliary joint device according to at least one of the foregoing improvement schemes and / or at least by an auxiliary joint method according to at least one of the foregoing improvement schemes, wherein the winding device has a combination of a right winding machine, a left winding machine, two right winding machines or two left winding machines and / or a combination of a right winding machine and a left winding machine.

[0058] The winding device can have only one right winding machine, one left winding machine or a corresponding combination of only right winding machines, a corresponding combination of only left winding machines and / or a combination of a right winding machine and a left winding machine.

[0059] The right winding machine should be understood in particular to mean a winding device in which the rotation of the winding turntable is clockwise, and in the case of the left winding machine, the rotation of the winding turntable is counterclockwise, where the viewing direction should be considered as looking at the winding turntable.

[0060] According to another improvement solution of the winding device, the winding device has a right winding machine and a left winding machine that are arranged mirror-symmetrically relative to each other, and the auxiliary joint device has corresponding configurations on the right winding machine and the left winding machine.

[0061] The auxiliary joint device is arranged according to the rotation directions of the right winding machine and the left winding machine, so that the convergence point will also be arranged at the respective correct positions of the right winding machine and the right winding machine.

[0062] Especially in the case of a combination of a right winding machine and a left winding machine, this may lead to different movement directions of the auxiliary joint device and especially the convergence joint device, and the convergence joint device will be arranged accordingly.

[0125] In Figures 1 to 5 In order to better view orientation and representation, a reference coordinate system XYZ is specified, where the X direction represents the length of the winding device, the Y direction represents the width of the winding device, and the Z direction represents the height of the winding device. Figure 1 The reference coordinate system in is Figures 2 to 5 's reference origin.

[0126] Figure 1A front view of the winding device 1 is shown. The winding device 1 is shown as a right winding machine 90 and a left winding machine 100 in a mirror-symmetrical manner. Except for the drafting unit 10 and the associated godet rollers 11 and 12, the right winding machine 90 has substantially the same component parts as the left winding machine 100.

[0127] In other respects, the right winding machine 90 has the same configuration as the left winding machine 100, wherein the component parts are arranged and configured in a correspondingly mirror-symmetrical manner. As a result, synthetic filaments can be wound on both the right winding machine 90 and the left winding machine 100.

[0128] Hereinafter, only one side of the winding device will basically always be described, either the left winding machine 100 or the right winding machine 90. The same component parts of the right winding machine 90 and the left winding machine 91 are all defined by the same reference numerals. For example, both the right winding machine 90 and the left winding machine 100 have winding spindles 51.

[0129] For example, for better and simpler illustration, Figure 1 the winding spindle device 50 of the winding machine 90 is shown. In Figure 1 the same shown component parts of the left winding machine are shown, but without the corresponding reference numerals.

[0130] As already described above, the winding device 1 has two winding devices arranged in a mirror-symmetrical manner relative to each other. However, the auxiliary joint device of the present invention can also be used for a winding device 1 having only one right winding machine 90 or only one left winding machine 100. The auxiliary joint device according to the present invention is particularly advantageous for the winding device 1 because the joint area is covered by the left winding machine 100, especially in the X direction of the extension direction of the relevant winding spindles 51, 52, and vice versa.

[0131] The auxiliary joint device according to the present invention facilitates the filament joint, especially at the winding positions of the winding spindles 51, 52, and allows a safe and simple joint and winding of the synthetic filament F.

[0132] For simplicity, hereinafter, the right winding machine 90 will be used to basically describe the winding device 1.

[0133] The right winding machine of the winding device 1 has a drafting unit 10, and the first godet roller 11 and the second godet roller 12 for drawing out and conveying the synthetic filament F are movably arranged on the drafting unit.

[0134] The synthetic filament formed by being extruded from a plastic melt in a melting device is preferably drawn out through the godet rollers 11 and 12, and then wound by means of the winding device to form a winding bobbin 8.

[0135] The winding bobbin 8 is wound onto the bobbin tube 9, which is removably wound onto the first winding spindle 51 and the second winding spindle 52.

[0136] The first winding spindle 51 and the second winding spindle 52 are rotatably mounted on a rotatable winding turntable 53. The first winding spindle 51 is in a so-called winding position WP, in which the synthetic thread F can be wound onto the bobbin tube 9 to form the winding bobbin 8.

[0137] The winding spindle 52 is in a so-called doffing position DP, in which the full winding bobbin 8 can be removed and the winding spindle 52 can be reloaded with an empty bobbin tube 9.

[0138] Figure 2 The winding positions SP.1 to SP.n are shown in a side view, and the winding bobbin 8 on the first winding spindle 51 is also shown in this way.

[0139] The winding turntable 53 can be rotated by a drive device 56 so that the first winding spindle 51 and the second winding spindle 52 can be rotated to the winding position WP and the doffing position DP, respectively.

[0140] The first winding spindle 51 has a first winding spindle drive device 54, which rotates the first winding spindle 52 at a predetermined speed to wind the synthetic thread. The same applies to the second winding spindle 52, which has a dedicated associated second winding spindle drive device 55.

[0141] The formation of the winding bobbin 8 by winding the synthetic thread F is achieved by the interaction of the first winding spindle 51 and the second winding spindle 52 and their rotation, the contact roller 54 and the traversing device 30. The contact roller 40 is pivotally mounted on the winding device by a pivot arm 41 and is detected, and the winding rotation movement is achieved through a pivot bearing 42. The detected rotation movement can be used for the open-loop and closed-loop control of the rotation of the winding device 1, especially the first winding spindle 51 and the second winding spindle 52, in order to take into account the growth of the winding bobbin 8 during the winding operation.

[0142] In order to obtain, for example, a so-called cross winding for the winding bobbin 8, a traversing device 30 is provided.

[0143] The traversing device 30 can have a rotor traversing mechanism 31, which has a traversing drive device 32.

[0144] The traversing drive device 32 rotates the rotor traversing mechanism 31 in the corresponding direction, so that the back-and-forth movement of the thread F can be achieved. As a result, the synthetic thread F is moved back and forth during the winding operation and the required winding bobbin 8 can be produced.

[0145] In order to enable the synthetic filament F to be wound to form a wound bobbin 8, the synthetic filament F is laid at the traverse positions CP.1, CP.2 to CP.n of the traverse device 20 by means of a first distribution device 20 in the winding device 1 and is laid at the winding positions SP.1, SP.2, SP.n by means of a second distribution device 60.

[0146] In particular, a convergence joint device 70 is used to assist in joining the synthetic filament F at the respective associated winding positions SP.1 to SP.n.

[0147] Figure 2 Side view showing the A-A section of the inside of the winding device, in particular the left winding machine 100.

[0148] The left winding machine 100 is characterized in that, during the winding of the filament F and / or in order to change the winding positions WP and doffing positions DP of the winding spindles 51 and 52, the winding turntable 50 and the winding spindles 51, 52 are moved to the left.

[0149] In the case of the right winding machine 90, the winding spindles 51 and 52 and the winding turntable 53 are moved to the right accordingly.

[0150] Figure 2 The drive motors 54, 55 of the winding spindles 51 and 52 and the arrangement of the winding turntable relative to the winding device 100 are shown in detail again. In addition, the relevant first distribution device 20 and second distribution device 60 and their respective traverse positions CP.1, CP.2 to CP.n and winding positions SP.1, SP.2, SP.n are shown more precisely.

[0151] The first distribution device 20 has a guide screw rod 21, which has a plurality of wire guides 22, and these wire guides can be moved to the relevant traverse positions CP.1 to CP.n.

[0152] Figure 2 It is shown in detail that each traverse position CP.1 to CP.n has its associated wire guide 22.1 to 22.n.

[0153] The first to nth wire guides 22.1 to 22.n can be moved along the guide screw rod 21, and can be moved to the relevant traverse positions 22.1 to 22.n and can be moved together adjacently to abut one end of the guide screw rod 21 in order to move the individual filaments F to their respective traverse positions CP.1 to CP.n.

[0154] The traverse device 30 follows an independent rotor traverse mechanism 31 and a relevant traverse drive device 32 in the filament running direction FR. After the traverse device 30 is a contact roller 40, which helps to lay the respective filament F on the surface of the wound bobbin 8 during the winding process of the wound bobbin 8.

[0155] In order to also perform and assist in the threading of the thread F which is distributed by the first distributing device 20 to the traverse positions CP.1 to CP.n corresponding to the relevant bobbin positions SP.1 to SP.n, a second distributing device 60 is provided. The second distributing device 60 is also understood as a lower replacement device and can move back and forth towards and away from the bobbin spindles 51, 52 in its bobbin position and assist in the splicing of the relevant thread F at the relevant bobbin positions SP.1 to SP.n of the respective bobbin spindles 51 or 52. The bobbin positions SP.1 to SP.n are also defined by the bobbins 9 which are removably applied to the bobbin spindle 51 or the second bobbin spindle 52.

[0156] First, the thread F has to be spliced to the bobbin 9. The second distributing device 60 with the thread grippers 63.1 to 63.2 movably mounted thereon assists in this process. The thread grippers 63.1 to 63.2 are movably mounted on the lever pivot arm 62, so that the first to n-th thread grippers 631 to 63.n can be moved to the relevant first to n-th bobbin positions SP.1 to SP.7 or to the relevant gripping positions on the relevant winding bobbins 8.

[0157] The splicing of the synthetic thread F to the second distributing device 60 and the relevant thread grippers 63.1 to 63.n is assisted by the converging splicing device 70, which is Figure 2 shown in the tilted position KP and the pivoted position SP.

[0158] The converging splicing device 70 can be moved relative to the winding device 1 in three dimensions to assist in the splicing operation on the second distributing device 20.

[0159] These three-dimensional movement ranges include different splicing positions or tilted positions.

[0160] Figure 2 The converging splicing device shown in the tilted position KP.

[0161] Figure 3 The converging splicing device 70 and the parking position PP are shown.

[0162] In the parking position PP, the converging splicing device 70 is moved and pivoted together, so that the doffing operation DP (removing the winding bobbin 8) and the winding operation WP (winding of the winding bobbin 8) can be safely carried out on the winding device 1.

[0163] The winding process on the winding device 1 only starts when the monitoring sensor 85 which can monitor the position of the converging splicing device 70 and its associated components detects that the converging splicing device 70 is in the parking position PP.

[0164] The monitoring sensor 85 forwards data and received signals to the controller of the winding device 1 via the sensor connector 34. The data lines that can be connected to the sensor connector 34 are not shown in these figures.

[0165] Figures 3 to 5 The illustrated embodiment of the converging joint device 70 has tilting feet 78, and the pivot arm 73 is pivotally mounted on the tilting feet via a joint 80.

[0166] The first link mechanism strut 74.1 and the second link mechanism strut 742 are also pivotally mounted on the pivot arm 73 via a joint 80.

[0167] The pivot arm 73 together with the first link mechanism strut 74.1 and the second link mechanism strut 742 form a guiding mechanism 81, through which the converging point 71 mounted on the bearing part 72 spaced from the joint 80 of the pivot arm 74 on the first link mechanism strut 74.1 can be moved to the pivot position SP or the joint position AP.

[0168] The converging point 71 is preferably designed in a hook shape and is provided for collecting a plurality of synthetic filaments F. As a result, the so-called converging or collecting of the synthetic filaments F can be carried out. At the converging point 71, the synthetic filaments F spread out in a fan shape merge at the joint position AP. As a result, the filament grippers 63.1 - 63.n of the second laying device 60 can pick up the synthetic filaments F one by one and can be moved to the relevant bobbin positions SP1 to SP.n.

[0169] The guiding mechanism 81 can be pivoted to the parking position PP and the joint position AP by the mechanism drive device 77, as Figure 4 and Figure 5 shown.

[0170] A stop 83 is provided above the mechanism drive device 77. The stop 83 prevents the pivot arm 83 from retracting too far in the parking position PP and possibly contacting its symmetrically arranged adjacent objects.

[0171] The mechanism drive device 77 is a pneumatic drive device in the illustrated embodiment. It is supplied with the corresponding pneumatic flow via the drive device connection head 82 to move the pivot arm 73 to the parking position PP or the joint position AP.

[0172] In addition, the converging joint device 70 can also be tilted to the tilting position KP, as Figure 4 shown. For this purpose, the tilting feet 78 are provided with a tilting mechanism 79. The tilting mechanism 79 has a joint around which the tilting feet 78 of the converging joint device 70 can be pivoted from the parking position PP to the tilting position KP.

[0173] If the pivot arm 73 is not in the pivot position SP or the joint position AP, the tilting of the converging joint device 70 can also be performed.

[0174] Figure 6 A block diagram showing method steps of an auxiliary splicing method for splicing a plurality of synthetic filaments at a plurality of winding positions SP.1 to SP.n in the case of a traversing device 30 and a second distribution device 60 arranged below the traversing device 30 by means of a converging joint device 70.

[0175] In a first step S1, a plurality of synthetic filaments F are distributed to a plurality of traversing positions CP.1 to CP.n by a first distribution device 20.

[0176] In step S2, the converging joint device 70 is tilted to a tilted position KP.

[0177] In step S3, the synthetic filaments F distributed at the traversing positions CP.1 - CP.n are then combined and spliced into the converging point 71 of the converging joint device 70.

[0178] Then, in step S4, the converging joint device 70 is tilted back to a parked position PP.

[0179] In step S5, the pivot arm is pivoted to a splicing position AP.

[0180] As a result, the synthetic filaments F are spread out in a fan shape, and in step S6, the plurality of filaments F are distributed to a plurality of winding positions SP.1 to SP.n by a second distribution device 60.

[0181] In step S7, the converging joint device 70 is tilted to the tilted position KP with the pivoted tilt arm to avoid hitting the winding spindles 51 or 52.

[0182] In step S8, the winding spindle 51 or 52 is then rotated to a winding position WP.

[0183] In step S9, the plurality of filaments F are spliced to a plurality of winding positions SP.1 - SP.n on the winding spindle 51 or 52 by a second distribution device 60. The winding spindle 51 or 52 is pre - set in rotation at a predetermined speed.

[0184] When the bobbin 9 is placed on the winding spindle 51 or 52, the filaments F located below the winding positions SP.1 - SP.n are cut by a cutting device on the second distribution device 60.

[0185] After splicing on the winding spindle 51 or 52, in step S10, the converging joint device 70 and the pivot arm 73 are tilted or pivoted back to the parked position PP.

[0186] As an alternative, after distributing the plurality of filaments F by the second distribution device 60, the pivot arm 73 can already be pivoted.

[0187] In step S10, before the converging joint device 70 is tilted back to the parking position PP, the pivot arm 73 can already be pivoted back to the parking position PP.

[0188] These method steps can be applied to the case of a winding device 1 having a right winding machine 90 and / or a left winding machine 100, or having two right winding machines 90 and / or two left winding machines 100.
