Description

Technical Field

[0001] The present invention relates to a method for automatically threading a plurality of synthetic yarns in a winding device as described in the upper concept part of claim 1, an apparatus for automatically threading a plurality of synthetic yarns in a winding device as described in the upper concept part of claim 9, and a system in which this method and apparatus are used.

Background Art

[0002] Based on the prior art, in a winding device equipped with godets, a shedding device (Changiereinrichgung) and a winding spindle, the synthetic yarns to be wound are set semi-automatically and / or automatically using a corresponding distributor and / or robot so that continuous winding of the winding package is possible, which is generally known.

[0003] However, the threading robot provided for this purpose is extremely expensive, and is more prone to errors and slower than a human operator, which may result in more waste products during the threading process.

[0004] Semi-automatic threading devices regularly require the assistance of a human operator. In particular, a first operator needs to be above the spinning nozzle or spinning plate from which the synthetic yarn is extruded, and in many cases, a second operator standing at the level of the winding device lower than the spinning plate by only one or two floors needs to throw the synthetic yarn to the second operator so that the second operator can receive the extruded synthetic yarn.

[0005] Only in this way can the threading of the winding device be carried out, in many cases, using a so-called suction pistol that guides the synthetic yarn into a waste container by the generated negative pressure for a long time until the synthetic yarn is threaded for winding and / or stretching in the winding device.

[0006] Both semi-automated mechanism processes and those implemented by kinematic robots are time-consuming, expensive, require at least two operators, and are prone to errors. [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] Therefore, the object of the present invention is to provide a method for automatically loading synthetic yarn in a winding device without the need for operator intervention.

[0008] The object of the present invention is also to provide a device for automatically loading synthetic yarn in a winding device, which also functions without the assistance of an operator, and to provide an associated system that integrates the method and the device. [Means for solving the problem]

[0009] The problem, in terms of the method according to the present invention, is solved by the features described in claim 1.

[0010] The problem, in relation to the apparatus according to the present invention, is solved by the features of the apparatus described in claim 9.

[0011] The problem, with respect to the system, is solved by a system having the features described in claim 17.

[0012] According to one aspect of the present invention, a method is provided for automatically winding multiple synthetic yarns in a winding device having a godet for drawing multiple synthetic yarns from a melt extruder and a winding spindle for winding multiple synthetic yarns at multiple winding positions.

[0013] The setup is carried out using an automatically controllable setup mechanism that defines the positions of yarn convergence points where multiple synthetic yarns approach each other, at setup points from the godet to the spinning beam.

[0014] In this specification, a melt extruder means, for example, a spinning beam equipped with a spinning plate for extruding a synthetic molten material.

[0015] However, the melt extruder may also be an injection molding machine, which has a corresponding spinning plate, and can extrude or press a molten material from this spinning plate through a corresponding extruder, thereby producing synthetic yarn.

[0016] The synthetic yarn is drawn through a godet towards a winding device, where it is wound onto a winding tube that is releasably locked to a rotating winding spindle.

[0017] In this specification, a "setting point" refers to a position in a winding device that is necessary for setting, transporting, and guiding the synthetic yarn to a corresponding winding device or winding spindle for winding the synthetic yarn.

[0018] To support the loading process, automatically controllable loading means are provided, which are installed in the winding device and enable the loading of synthetic yarn into each godet, twill device and / or winding spindle without the need for additional human operators or mobile robotic operators in the winding device.

[0019] All the necessary mechanisms for this purpose are positioned adjacent to or near the required locations within the winding device.

[0020] In this specification, a yarn convergence point refers to a position in a winding device that specifies the convergence of multiple synthetic yarns at a predetermined location.

[0021] The yarn gathering point may be, for example, the suction opening of a suction pistol or the guiding groove in a winding device. This yarn gathering point is formed such that a plurality of synthetic yarns are gathered from the yarn curtain into one yarn bundle. The position of the suction opening can be automatically controlled and moved using the associated guiding means.

[0022] According to one configuration of the method, a plurality of synthetic yarns are gathered at yarn gathering points located at various positions in the winding device, individualized using a winding position moving device, and guided in the winding device.

[0023] What is special in the method according to the present invention is that, in order to automatically guide these yarns, these yarns are gathered at a predetermined yarn gathering point from the yarn curtain and then individualized into yarns arranged at intervals from each other again for accurate positioning at a predetermined winding position.

[0024] As used herein, the term "synthetic yarn" means a synthetic yarn extruded from a plastic melt and having a number of filaments.

[0025] The term "plurality of synthetic yarns or yarn curtain" means a number of or a plurality of synthetic yarns. In the yarn curtain, the synthetic yarns are arranged at intervals from each other.

[0026] According to another configuration of the method, the position of the yarn gathering point is arranged at various positions in the winding device depending on each guiding point in the winding device. What should be noted in this configuration is that, according to a predetermined guiding point such as the winding position in a godet, a dobby device, and / or a winding spindle, the yarn gathering point is correspondingly moved in the winding device, and the yarn curtain is gathered at the associated yarn gathering point for the new guiding position.

[0027] According to another configuration of the method, the yarn gathering point is activated and operated by activating respective automatically controllable guiding means.

[0028] The automatically controllable actuating means can be, for example, a movable swivel arm and / or an actuating roller that can move or automatically travel to a set yarn convergence point by means of a corresponding path and / or guide and / or swivel point, thereby enabling correct and accurate positioning of the composite yarn at the relevant position of the winding device.

[0029] According to another configuration of the method, before the engagement and distribution of the plurality of composite yarns at each engagement point, the movement of the final position of the yarn convergence point is carried out. According to the present invention, an assembly is carried out at the corresponding yarn convergence point before the engagement. The yarn convergence point moves upward from the suction position near the winding spindle in the opposite direction to the yarn running direction towards the godet, at which time the respective final positions of the movement change, and these convergence points move back towards the winding spindle from the godet.

[0030] This is carried out simply by using the automatically actuating means in the winding device, and for this purpose there is no need for an operator to be involved. According to one configuration of the method, after the assembly of the plurality of composite yarns at each yarn convergence point, the plurality of assembled composite yarns are spaced apart into yarns arranged at intervals in accordance with the relevant winding positions.

[0031] The assembly at the yarn convergence point serves for the simple engagement of the yarns at each element of the winding device. The individualization of the plurality of yarns is necessary when it is desired that the yarns be engaged, for example, in a dobby device and / or on a bobbin at the winding spindle.

[0032] ]This individualization is also carried out by means of the correspondingly related devices in the winding device, so that it is also possible to engage the individual composite yarns at the relevant winding positions.

[0033] According to one alternative configuration of the method, a group of combined synthetic yarns are spaced apart from each other using a first winding position moving device and / or a second winding position moving device, above the winding device in the opposite direction to the direction of travel and / or below the winding device in the direction of yarn travel.

[0034] Arranging multiple synthetic threads at intervals from one another is particularly necessary at the relevant winding location, so that the synthetic threads can be wound onto the relevant winding tube, which is located on the winding spindle and is releasably locked.

[0035] The winding position moving device may, for example, have a moving roller which is movable to each winding position via a rail and / or has a corresponding thread guide which is reciprocally pivotable in the area of ​​the winding spindle along a rotatably guided rail and is also capable of traveling toward the individual winding positions accordingly.

[0036] According to one configuration of the method, the following steps are taken: - The step of preparing a yarn curtain consisting of multiple synthetic threads between the winding spindle and the sliding mechanism next to the godet, - A step of forming a first thread convergence point at the suction opening of the suction pipe adjacent to the winding spindle, -The suction pipe is rotated toward the guide groove in the winding device to move the first thread convergence point of the thread curtain to the second thread convergence point, thereby inserting the thread curtain into the guide groove. - The step of setting up the thread curtain on the rigging attachment that defines the fourth thread convergence point, using a rotatable rigging arm that defines the third thread convergence point, - The step of inserting the thread curtain into the thread guide comb using a movable sliding mechanism, - The step of setting the thread curtain on the Godet using a mechanism roller, - The steps of individualizing the yarn curtain into yarns spaced apart from each other at associated winding positions corresponding to a traverse device for the synthetic yarn, using a first winding position moving device, - The step of rotating the suction opening from the first thread convergence point to the sixth thread convergence point in order to set the thread curtain on the second winding position moving device, - A step of individualizing the thread curtain to the corresponding winding position on the winding spindle using a second winding position moving device, -The step of setting the individualized threads at the winding position on the winding spindle using a second winding position shifting device, This will be implemented.

[0037] The setup steps described above allow the yarn curtain from the melting extruder to be automatically set up in the winding device without the involvement of human operators or robotic operators. Since all the necessary setup means are located and formed in the winding device, the yarn curtain can be set up completely automatically at each winding position.

[0038] Another embodiment of the apparatus provides a device for automatically winding multiple synthetic yarns in a winding device, the device having a godet for drawing multiple synthetic yarns from a melt extruder and a winding spindle for winding multiple synthetic yarns at multiple winding positions.

[0039] According to the present invention, an automatic thread laying device is provided at each rigging point in the winding device to define the thread convergence point, and the synthetic thread can be laid at each rigging point using this thread laying device.

[0040] As mentioned above, a thread convergence point refers to a point where multiple synthetic threads from a thread curtain come together, so multiple synthetic threads can be gathered and set up at related locations.

[0041] It should be noted here that the gathered synthetic threads form a bundled thread curtain, in which the individual threads may be placed close to each other. However, in order to arrange the bundled thread curtain, for a further setup process, it is necessary to individualize the bundled thread curtain into thread curtains where the threads are spaced apart from each other, and in these spaced-apart thread curtains, the individual threads are spaced apart from each other, and this spacing is determined by the spacing between the individual winding positions.

[0042] According to one configuration of the apparatus, a yarn convergence point is formed by gathering the yarn curtain using each yarn laying device, and the gathered yarn of the yarn curtain is then individualized using a first winding position moving device and a second winding position moving device to be loaded onto a winding spindle at the winding position.

[0043] Gathering the thread curtain at the thread convergence point simplifies the setup at each individual setting position of the winding device, and individualization to subsequent winding positions enables winding on the winding spindle provided for that purpose.

[0044] According to one configuration of the apparatus, each thread laying device is formed to be movable, fixed in position, on or beside a winding device, in order to form the first to sixth thread convergence points.

[0045] The types and models of laying devices in winding devices are formed in various ways according to their function and challenges. Therefore, they can be directly attached to the winding device or attached at regular intervals, and thus can also perform the necessary movements of automatic rigging or laying devices.

[0046] In another configuration of the device, the thread laying device has a suction opening to form a first thread convergence point or a sixth thread convergence point, a rigging guide groove to form a second thread convergence point, a rigging swivel arm to form a third thread convergence point, a rigging attachment to form a fourth thread convergence point, and / or a rigging swing point to form a fifth thread convergence point, and a sliding rigging device to set the thread curtain on the winding device.

[0047] The thread setting device described above may be installed at a suitable location depending on the configuration of the winding device.

[0048] However, the selection of the line rigging device is not limited to the embodiments described above. It is also possible to provide specialized rigging devices that combine and / or further individualize the functions of individual rigging devices.

[0049] According to one configuration of the device, the suction opening is formed in a suction pistol equipped with a suction tube, the rig guide groove is formed by a guide member, the rig swivel arm is formed by a holder equipped with a swivel element, the rig attachment part is formed by a guide member, the rig swinging part is formed by a swivel arm swinging body equipped with a rig roller, and the sliding rig device has a rig lever that can travel laterally with respect to the thread travel direction.

[0050] According to the configurations described above for each yarn laying device, various mechanical mechanisms may be provided to enable the winding device to load synthetic yarn into the winding device by an automatically controllable device in the winding device.

[0051] According to the present invention, which is designed for automatic setup, various means are used for the thread laying device, and these means can also be retrofitted to existing setup devices or winding devices.

[0052] According to one special configuration of the apparatus, the first winding position moving device has one guide rail and a plurality of mechanism rollers, which are movable along the guide rail to a corresponding winding position on the winding spindle, and the first winding position moving device is positioned above the twill swing device in the opposite direction to the direction of yarn travel.

[0053] In another configuration of the device, the second winding position moving device has a pivoting body that is reciprocable between a distribution position for distributing yarn and a setting position for setting yarn on the winding spindle, and a yarn guide rail equipped with a plurality of movable yarn guides, the yarn guide rail being movable to the winding position on the winding spindle, and the second winding position moving device is positioned below the twill swinging device in the yarn travel direction.

[0054] The dual winding position shifting devices allow the bundled yarn to be individually wound to individual winding positions above and below the winding device, thereby enabling the yarn to be wound onto the winding tubes locked to the winding spindle.

[0055] According to another configuration of the apparatus, the mechanism in the winding device for the yarn curtain includes a godet and a winding device, and a winding spindle with associated winding positions.

[0056] The mechanism may also have other parts and / or components of the winding device.

[0057] This specification refers to important locations in a winding device where the synthetic yarn should be threaded. These may include godets, and may also include heated godets suitable for temperature control of the synthetic yarn. However, it is possible to prepare new threading locations in the winding device by novel or supplementary components, such as a second entanglement device located next to the godets, where precise threading of the synthetic yarn is required.

[0058] The traversing device may have a blade traverser and / or a belt-driven finger traverser. In the blade traverser, traversing is performed using rotors that rotate in opposite directions, and in the finger traverser, using a thread guide that is reciprocable by a belt.

[0059] The winding spindle may be mounted on a winding turret, which allows for uninterrupted winding and / or doffing. That is, the winding turret has at least two winding spindles.

[0060] According to another aspect of the present invention, a system is provided for automatically setting up a plurality of synthetic yarns at a plurality of winding positions using an automatically controllable setting means in a winding device, the system having an apparatus having at least one of the configurations described above, the apparatus being configured to carry out a method according to at least one of the method configurations described above.

[0061] Next, the method and related apparatus according to the present invention will be described in detail with reference to the accompanying drawings, by several embodiments of the apparatus and method according to the present invention. [Brief explanation of the drawing]

[0062] [Figure 1] This is a schematic longitudinal side view showing a winding device equipped with a thread laying device according to the present invention. [Figure 2] Figure 1 is a schematic side view in the width direction showing the winding device and thread laying device. [Figure 3.1] This figure shows a schematic side view of the winding device and the first winding position moving device at the start of the setup process for the first winding position moving device, and a detailed view showing the automatic setup means of the yarn laying device according to the present invention in large dimensions. [Figure 3.2]This is a schematic partial cross-sectional view showing the winding device and the first winding position moving device shown in Figure 3.1 during the first rigging step of the first winding position moving device. [Figure 3.3] This is a schematic partial cross-sectional view showing the winding device and the first winding position moving device at another setting position, where the first winding position moving device has set up the thread curtain according to the first winding position. [Figure 4] This is a schematic side cross-sectional view of the winding device shown in Figure 1, along with a second winding position moving device for positioning multiple threads at a second winding position below the winding device. [Figure 5] This is a partial diagram showing a second winding position moving device in the individualization step of synthetic yarn to the winding position. [Figure 6] This flowchart schematically shows the individual loading steps of a method for automatically loading multiple synthetic yarns into the winding device shown in Figure 1. [Modes for carrying out the invention]

[0063] The diagram shows the respective reference coordinate systems x, y, and z, representing the height (z), length (x), and width (y) in each line of sight direction.

[0064] It is desirable that the line of sight direction be defined and shown using the reference coordinate system x, y, and z, which will allow for a better understanding of each figure.

[0065] Figure 1 shows a schematic side view in the zx direction plane of a winding device 100, which is equipped with a device for automatic setting, and is hereafter referred to as a yarn laying device 1, together with a spinning beam equipped with a melting extruder 400 or a spinning plate 401.

[0066] The melting extruder 400 may also be a melting injector device, in which case the molten material is extruded directly to the winding device 100 via an injection nozzle, rather than through the spinning plate 401.

[0067] The melt extruder 400 releases multiple synthetic yarns in the form of a yarn curtain V, which is then set up at individual setting positions A in the winding device 100 using the yarn laying device 1, and can be individually positioned above and below the winding spindle 140 at predetermined first and second winding positions 10.1 to 10.n.

[0068] N is a substitute symbol for a natural number, representing the number of winding positions, which is a natural number in this specification.

[0069] In the illustrated embodiment, there are five winding positions. The winding position can be changed depending on the length of the winding spindle 140 and the length of a given winding device, and the number n of winding positions 10.1 to 10.n depends on the number n of winding tubes 160 that can be mounted on the winding spindle 140 and the number n of associated winding devices 130.

[0070] The winding device 100 shown in Figure 1 includes a godette 8, a twill swinging device 130, a crimping roller 120, and a winding spindle 140, the winding spindle 140 being rotatably mounted and driven by a winding spindle turret 150. Two godettes 8 are typically required to pull out the synthetic yarn curtain V.

[0071] In the illustrated diagram, the winding device 100 is shown with the synthetic yarn F fully loaded, and the individual synthetic yarns F.1, F.2 to Fn are loaded at their respective winding positions 10.1, 10.2 to 10.n on the winding spindle 41.

[0072] For accurate setup, according to the present invention, a yarn laying device 1 equipped with setup means is important, and these setup means are indicated by reference numeral A in Figure 1, and reference numeral A also indicates an important setup position for the synthetic yarn curtain in the winding device 100.

[0073] In the winding device 100, there are predetermined setting positions A and thread convergence points K1 to K6 for automatically setting up the thread curtain V, and thread convergence point K6 is shown in detail in Figure 4.

[0074] The thread convergence points K1 to K6 are movable and / or fixed locations where the synthetic thread curtain V is preferably bundled and set up, thereby enabling the subsequent setting up at predetermined setting positions A to be carried out automatically.

[0075] In this specification, an automatic mechanism means an independent mechanism of a winding device 100 equipped with a controllable mechanism A, such a mechanism does not require assistance from a human operator or a kinematic robot during the mechanism setting process.

[0076] The mechanism for the thread curtain V can be independently implemented by a winding device 100 equipped with an associated thread laying device 1.

[0077] As can be seen from Figure 1, the winding device 100 has a godet holder 190 on which the first and second godets 8 are provided.

[0078] Godets 8 can be used to draw the yarn curtain from the melt extruder and guide it toward the winding spindle 140. In the illustrated embodiment, the winding device 100 is provided with two godets 8. Depending on the synthetic yarn F to be drawn, the type and number of godets in the winding device 100 may be configured in other ways.

[0079] A rigging roller 12 is provided in the Godet 8 for setting the thread curtain V, and this rigging roller 12 is shiftable along a guide trajectory so that the thread curtain V is inserted into the entanglement device 14.

[0080] When a thread breaks, a thread guide comb 6 equipped with a thread break cutter that cuts the thread curtain V is activated, thereby allowing the continuously supplied synthetic thread F to be discharged via the thread break suction unit 4.

[0081] The Godet holder 190 has several of the rigging means 30, 20, 18, 16, 8, and 28 of the thread laying device 1, and these rigging means are arranged, for example, at thread convergence points K1 to K6.

[0082] The thread convergence point K3 in the Godet holder 190 has a rigging swivel arm 18, which can swivel toward the Godet holder 190 when the synthetic thread F is rigged in the winding device 100, thereby rigging the thread curtain V in the thread rigging attachment 16 that defines the fourth thread convergence point K4 in the Godet holder 190.

[0083] In order to insert the thread curtain V into the thread guide comb 6, the sliding mechanism 2 is then used to insert the thread curtain V into the thread guide comb groove of the thread guide comb 6 (see also the detailed diagram in Figure 3.1), which will be shown and described more precisely below with reference to Figure 3.1.

[0084] In order to set up the synthetic yarn curtain V at the relevant winding positions 10.1 to 10.n in the twill winding device 130 and the winding spindle 140, the yarn group V is also individualized at the previously shown yarn convergence points K1, K2, and K6 via the first winding position moving device 700 and the second winding position moving device 800. Figure 1 is shown so that only the first winding position moving device 700 is visible.

[0085] The second winding position shifting device 800 is shown in Figure 4. Traversing of the individualized synthetic yarns F.1, F.2 to Fn is performed using the associated traverse device 130, where a specific traverse device 130 is provided for each synthetic yarn F.1 to Fn. The traverse device 130 may be a birotor traverse device and / or a finger traverse device.

[0086] A crimping roller 120 is provided in addition to form the winding package 240 or to engage the associated winding tube 160 locked to the winding spindle 140, which crimps the traversed synthetic yarn F.1 to Fn at the associated traversing position 130 at the winding position 10.1 to 10.n to ensure that it is securely traversed there.

[0087] The winding spindle turret 150 and the winding device 130 are drivably held on a mechanical frame 300 that forms a holding device for the winding device 100. The winding spindle turret 150 allows each winding spindle 140 to rotate to a winding position for winding yarn F onto the winding tube 160 and to a doffing position for removing the winding package 260 together with the winding tube 160. Figure 1 shows a winding spindle with an empty winding tube in the doffing position and a winding tube with a winding package in the winding position.

[0088] Supplementary information is shown in Figure 1, which illustrates other rigging mechanisms 28 and 30 for the thread laying device 1. These rigging mechanisms 28 and 30 have and define thread convergence points K1, K5 and K6, which are necessary for rigging the thread onto the winding spindle 140.

[0089] The thread group V is first provided, set up, and held at the thread convergence point K1, which is formed and defined by the suction opening 30 of the rigging suction pipe 22.

[0090] Since a negative pressure can be continuously introduced and / or generated using the rigging suction pipe 22, the thread curtain V can be rigged there for a first rigging step that also includes the thread convergence point K1.

[0091] The rigging suction pipe is rotatable toward the winding spindle 140 in the Y direction for the rigging via the thread convergence point 6, thereby allowing a second winding position moving device 800 (not shown here) to individualize the filament curtain at winding positions 10.1 to 10.n for the winding spindle 140.

[0092] In addition to this configuration, the rig suction pipe 22 has a rig swinging point 28, which can reciprocate in the X direction or longitudinal direction of the winding spindle 140 using a swivel rig device.

[0093] Furthermore, Figure 1 also shows a second thread convergence point K2, which forms a rigging guide groove 20. Multiple synthetic threads F of the thread curtain V can be automatically inserted into this rigging guide groove 20 using a suction opening 30 that can rotate automatically.

[0094] Figure 2 shows a schematic widthwise side view of the winding device 100 of the automatic yarn laying device 1 in the ZY plane, viewed in the X-longitudinal direction.

[0095] Figure 2 shows, in particular, the positions of the first and second winding spindles 140 in the winding turret 150 equipped with an already wound winding package 260. Furthermore, the thread path in the thread travel direction R from the sliding device 2 to the winding package 260 can be inferred from the widthwise side view.

[0096] Furthermore, the positions of the thread breakage suction unit 4 and the thread guide comb 6 for the thread breakage cutter are clearly visible in the widthwise side view, and the arrangement of the godette 8 equipped with the related drive device is also clear.

[0097] Furthermore, a portion of the thread laying device, in the form of the mechanism attachment part 16 and the mechanism swivel arm 18, is clearly visible at the position where it was launched.

[0098] Furthermore, the holder of the first winding position moving device 700 can be seen, and the position of the rigging guide groove 20 is merely indicated and is no longer used after rigging and during the winding process, as shown in Figure 2.

[0099] Furthermore, a suction opening 30 equipped with a rig suction pipe 22 can be seen, and in addition to the rig on the winding spindle 140, a rig swinging point 28 equipped with an associated swivel rig device 28 can be recognized in this suction opening 30. The swivel rig device 26 has a rig swinging point 28 formed therein.

[0100] Figure 3.1 shows a schematic cross-sectional view of the winding device 100 together with the first winding device 700 after the thread curtain V has been set up on the godet holder via the thread laying device. The thread laying device has individual setting means such as a suction opening 30 that forms the first thread convergence point K1, a setting guide groove 20 that forms the second thread convergence point K2, a setting swivel arm 18, and a setting addition part 16, together with the associated sliding setting device 2.

[0101] Figure 3.1 shows in detail, on the right side in the X direction, in an enlarged view and in a plan view in the ZY direction, a thread insertion mechanism equipped with a mechanism guide groove 20, a mechanism swivel arm 18, a mechanism attachment part 16, and a sliding mechanism device 2. In this figure, the movable members of the thread insertion mechanism are indicated with motion arrows showing their respective directions of movement.

[0102] In the installation position shown in Figure 3.1, the thread curtain V is already inserted into the thread guide comb 6, and the thread curtain V is guided stepwise through by the thread laying devices 30, 20, 18, 16, and 2 described above, and the thread curtain V is installed stepwise at the thread convergence points K1, K2, K3, and K4, respectively.

[0103] The synthetic yarn F is now loaded into the winding device 100, which allows the yarn curtain V to come into contact with the godet 8 and be inserted into the entanglement device 14. Next, the individualized synthetic yarn F is loaded at winding positions 10.1 to 10.n by the twill swinging device 130.

[0104] Figure 3.1 shows the next rigging step via the rigging roller 12, which allows the individualization of the synthetic yarn F into F.1 to Fn after the insertion of the yarn curtain V into the entanglement device 14 to be performed using the rigging roller 170 of the first winding position moving device 700.

[0105] Furthermore, Figure 3.1 shows the actual position and orientation of the thread guide comb 6, in which the thread curtain V or individual synthetic threads F are inserted into the grooves of the thread guide comb.

[0106] The thread guide comb shown on the Godet holder 190 is briefly shown for better understanding, and here the effective position of the thread guide comb is functionally and schematically shown in the following drawings to better clarify the differences from the individual components.

[0107] Figure 3.2 shows the next setting step in the Godet holder 190 into the entanglement device 14, in which the setting roller 12 travels beyond the position of the entanglement device 14, thereby inserting the filament curtain V into the entanglement device 14.

[0108] As can be seen similarly from Figure 3.2, the thread curtain V is attached to the two godettes 8 and is still inserted into the rigging guide groove 20 at the thread convergence point K2.

[0109] To individualize the thread curtain V into individual threads F.1 to Fn, Figure 3.3 is now referred to. In Figure 3.3, the thread curtain V is guided out from the rigging guide groove 20 using a movable suction part 30, and this movement is achieved by the rigging swing part 28.

[0110] The rig swinging point 28 is moved to a specific position using a swivel rig device 26, which allows the rig rollers 170, which are offset from each other in the Y direction, to capture individual synthetic threads F.1 to Fn and move them to the corresponding first winding positions 10.1 to 10.n. This individualization is shown in Figure 3.3.

[0111] Figure 4 shows a schematic partial cross-sectional view of the winding device 100 shown in Figure 1, together with the second winding position moving device 800.

[0112] The second winding position moving device 800 is rotatably positioned on the machine frame 300 and has a swivel holder 110, which is reciprocable between the winding spindles 140 using an actuator, thereby allowing the yarn guide 101 to swivel toward the synthetic yarn F along the yarn guide rail 99.

[0113] Furthermore, Figure 1 shows a part of the yarn laying device 1, which has a suction opening 30 that gathers the yarn at yarn convergence points K1 and K6.

[0114] Furthermore, Figure 4 shows a winding spindle turret 150 and a winding spindle 140 equipped with a winding package 240, which is provided for the doffing position.

[0115] Furthermore, Figure 4 shows the winding position of the winding spindle turret 150, the rotational direction associated with the winding spindle turret 150, and the winding tube 160 on the winding spindle 140, which is positioned with the synthetic yarn F for winding.

[0116] The rotational direction of the winding spindle 140 and the rotational direction of the crimping roller 120 are indicated by corresponding rotational arrows. Furthermore, the rotational range of the suction opening 30 for the mechanism in the second winding position moving device 800 is also shown.

[0117] Figure 5 shows various diagrams of the second winding position moving device 800 in the YX plane in plan view, and also shows the setting means 28,30 of the thread laying device 1 at the sixth thread convergence point K6 in the ZX plane.

[0118] As can be seen in Figure 5, the rigging swinging point 28 prepares the synthetic thread so that it can be individually positioned using the thread guide 101 of the second winding position moving device 800 and rigged at the corresponding winding positions 10.1 to 10.n on the winding spindle 140.

[0119] When the swivel holder 110 of the second winding position moving device 800 rotates appropriately toward the winding spindle 140, centered on the X-axis direction, the individualized threads F.1 to Fn can be loaded onto the winding tube 160, which is releasably locked to the winding spindle.

[0120] The second winding position moving device 800 shown herein has a compressed air pipeline 801 equipped with an associated compressed air control device 803, and using this compressed air pipeline 801, the thread guide 101 can travel to the associated winding positions 10.1 to 10.n. The thread guide 101 is guided to the associated winding positions 10.1 to 10.n by compressed air via the thread guide rail 99.

[0121] Figure 6 shows a schematic flowchart illustrating the individual method steps for loading the synthetic yarn into the winding device 100 shown in Figure 1.

[0122] In step S1, a yarn curtain V made of multiple synthetic threads is prepared in the godet holder 190 between the sliding mechanism 2 next to the godet 8 and the winding spindle 140.

[0123] This step is shown in Figure 1, and it allows the molten material to be prepared at the suction opening 30 via the molten extruder 400 so that the formed thread curtain V can be set up. This setup at the suction opening 30 causes the formation of the first thread convergence point K1 in step S2, at which point the thread convergence point K1 is adjacent to the winding spindle 140 in the doffing position.

[0124] Subsequently, in step S3, the movement of the first thread convergence point K1 of the thread curtain V to the second thread convergence point K2 defined by the rigging guide groove 20 is performed by the rotation of the rigging suction pipe 22 toward the rigging guide groove 20 in the winding device 100. This inserts the thread curtain V into the rigging guide groove 20.

[0125] In step S4, the thread curtain V is attached to the winding device 100, and to the additional mechanism 16 that defines the fourth thread convergence point K4, using the rotatable mechanism swivel arm 18 that defines the third thread convergence point K3.

[0126] Next, in step S5, the thread curtain V is inserted into the thread guide comb 6 using the movable sliding mechanism 2.

[0127] In step S6, the thread curtain V is set up on the godette 8 using the rigging roller 12.

[0128] Subsequently, in step 7, the individualization of the yarn curtain V to the yarns F.1 to Fn, which are spaced apart from each other, is performed using the first winding position moving device 700 to the associated winding positions 10.1 to 10.n corresponding to the traverse device 130 for traversing the synthetic yarns F.1 to Fn.

[0129] In step S8, the suction opening 30 is rotated from the first thread convergence point K1 to the sixth thread convergence point K6 in order to set the thread curtain V on the second winding position moving device 800. This allows the thread curtain V to be individually positioned at the relevant winding positions 10.1 to 10.n on the winding spindle 140 via the thread guide 101 using the second winding position moving device 800 in step S9.

[0130] In step S10, the second winding position moving device 800 is then used to move the winding tube 160 to the corresponding winding positions 10.1 to 10.n. During this movement, the swivel holder 110 is swiveled to the corresponding position adjacent to the winding tube 160, so that the synthetic yarns F.1 to Fn engage with the winding tube 160 and the corresponding engagement grooves in the winding tube 160.

[0131] After engagement with the winding tube 160, winding of the synthetic yarns F.1 to Fn begins at winding positions 10.1 to 10.n of the winding tube 160.

[0132] Since threads F.1 to Fn are cut below the winding spindle by the thread guide 101, accurate winding on the winding tube 160 is possible.

[0133] This completes the automatic rigging process in the winding device 100, and the rigging is performed fully automatically without the assistance of an operator.

[0134] The methods and related apparatus described above are preferably used in a single system, but in other embodiments, the thread laying device itself can be integrated into several mechanism units, and in such mechanism units, supplementary guide rails and drive units are provided, so that a single mechanism unit can perform multiple functions.

[0135] Furthermore, in embodiments of the winding device 100 not shown herein, the godet holder 190 may be provided with a second entanglement device and / or a third godet 8, which can generate a supplemental entanglement mechanism depending on the position, and which, according to the present invention, is formed to form a supplemental thread convergence point. Thus, such embodiments are also covered by the claims described below. [Explanation of Symbols]
