Description

[Technical Field]

[0001] The present invention relates to a winding device for winding filament bundles onto a bobbin to form a package, the winding device being specially developed to facilitate the automatic feeding of yarn to the winding device. [Background technology]

[0002] The closest prior art, WO 2021 / 144300, discloses a winding device that does not allow the thread to be threaded automatically through the winding device, a limitation that requires manual intervention, which is time-consuming and inefficient. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION It is an object of the present invention to provide a winding device which allows automatic feeding of a filament bundle to the winding device. [Means for solving the problem]

[0004] This problem is solved according to the invention by a winding device having the features of claim 1.

[0005] According to one aspect of the present invention, there is provided a winding device for automatically distributing filament bundles, the winding device having a plurality of winding positions capable of winding a plurality of filament bundles onto a plurality of winding tubes to form a package, the winding tubes being mountable on a spindle at the winding positions, a plurality of yarn guides being guideable in a guide track positioned above the spindle and spaced apart from the spindle, the guide track having a first track section in which the plurality of yarn guides are stored in a storage position and a third track section in which the plurality of yarn guides are distributed to the winding positions at a setup position, the first track section extending substantially perpendicular to the third track section in a direction away from the spindle.

[0006] A winding machine is a device capable of winding a plurality of synthetic yarns or filament bundles made from a plastic melt onto a winding tube placed over a spindle to form a package.

[0007] The spindle may be a chuck equipped with a device for releasably locking a winding tube onto which the filament bundle is wound to form the package.

[0008] The plastic melt is extruded through a spinning nozzle above the winding device and from the spinning nozzle in the direction of yarn travel towards the winding device to form filaments.

[0009] A guide track on which a plurality of yarn guides are guided is positioned above the spindle in the winding device, the guide track being oriented in a direction opposite to the yarn running direction to the spindle.

[0010] According to a preferred configuration of the winding device, the guide track has a second track section connecting the first track section and the third track section to each other such that the first track section is at an angle to facilitate movement of the yarn guide from the storage position to the winding position.

[0011] The track sections of the guide track are assembled one after the other. The guide track may also be formed integrally, in which case the desired shape can be obtained by curving the guide track and / or formed in a mold.

[0012] According to a further preferred configuration of the winding device, the plurality of thread guides are movable between a storage position and a spooling position, and in the storage position the plurality of thread guides are arranged substantially adjacent to one another and in the spooling position are spaced apart from one another.

[0013] In the retracted position, the thread guides are grouped next to each other, so that little space is required for the thread guides, and the track sections are shaped so that all thread guides have sufficient space.

[0014] In the setup position, the yarn guides are spaced apart to feed the filament bundles at the corresponding winding positions, so that the traverse devices positioned within the traverse housing can also grip the corresponding filament bundles, allowing the formation of a package.

[0015] According to a particularly preferred configuration of the winding device, the third track section extends substantially parallel to and spaced apart from the spindle in the first plane and is inclined at a guide track inclination angle in the second plane, so that one end section of the third track section positioned adjacent to the godet has a greater distance from the spindle than the other end section of the third track section inclined towards the spindle.

[0016] The track sections of the guide track are arranged in respective planes parallel to the spindle, perpendicular to the spindle and / or inclined to the spindle, depending on the line of sight to the winding device.

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

[0018] A plurality of yarn bundles are wound up in the winding device. For this purpose, the yarn bundles are guided to a godet at predetermined intermediate intervals. A yarn catcher is provided for each yarn bundle, which protrudes beyond the guide track at a predetermined interval so that the yarn catcher can grip the corresponding yarn bundle and transport it to the corresponding winding position.

[0019] According to a further preferred configuration of the winding device, the distance between the guide track and the yarn guide holder is largest at the first winding position and smallest at the n-th winding position, so that each yarn guide holder can grip the yarn bundle.

[0020] The spacing of the yarn guides relative to the guide tracks depends on the corresponding winding position. Optimally, the spacing of the yarn guides relative to the guide tracks is greatest for the first winding position and decreases for the yarn guides for each subsequent winding position.

[0021] According to a particularly preferred configuration of the winding device, the yarn guide holder has a yarn catcher at its end section opposite the guide track, by means of which one filament bundle is caught for each winding position and fixed in position during movement along the guide track.

[0022] To catch the filament bundle, the yarn guide may have a yarn catcher, which may be a roller with a circumferentially extending catch notch and / or a catch hook, where it is important that the yarn catcher can reliably catch the filament bundle and guide it to the corresponding winding position without damaging the filament bundle.

[0023] According to a preferred configuration of the winding device, the yarn bundles are gathered together by a supply suction gun when set at the winding position, so that each yarn bundle from the yarn guide can be gripped as it moves to the set position.

[0024] The feed suction gun is designed to catch the unwound filament bundle and guides the unwound filament bundle to a collection container. When the filament bundle is positioned at the winding position, the filament bundle may be wound onto the winding tube.

[0025] According to a further preferred configuration of the winding device, the winding device has a godet support with a first godet and a second godet, and a movable winding roller for winding the filament bundle is positioned between the first godet and the second godet.

[0026] The first and second godets pull the filament bundle from the spinning nozzle and guide it in the yarn running direction toward the winding position. Between the godets, a movable take-up roller is moved by a slider guide mechanism, which assists in taking up the filament bundle at the winding device.

[0027] According to a particularly preferred configuration of the winding device, the winding device has a first spindle with a first spindle drive and a second spindle with a second spindle drive, the first spindle and the second spindle being movable between a winding position for winding to form a package at the respective winding position and a doffing position for removing the package from the first and / or second spindle.

[0028] To form the packages, the spindles are rotatable about their axes and each has its own package drive which controls the rotation of the spindle, thereby allowing the spindle to rotate at a sufficient number of revolutions to form the package.

[0029] The cooperation of the winding drive with the other components of the winding device, such as godets and yarn guides, is controlled in a closed-loop and / or open-loop manner by a control device, which requires automatic loading of the filament bundle on the winding device without the intervention of at least a human operator.

FIG. DETAILED DESCRIPTION OF THE INVENTION

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

[0032] 1 and 2 show the winding device 1 in a longitudinal overall view and a side view, respectively. The number of winding positions is designated W1.1 to Wn, where n may be a natural number greater than 4. Depending on the length of the spindles 8, 9, the number may include more than four winding positions. In both figures, the illustration is simplified. Depending on the length of the spindles, there may be more or fewer winding positions than shown. The number of winding positions W1.1 to Wn also defines the number of traverse devices provided in the traverse housing 4 for traversing each filament bundle F.

[0033] The winding device 1 includes a plurality of winding positions W.1 to Wn where a plurality of filament bundles F can be wound onto a plurality of winding tubes 12 to form a package .

[0034] The winding tube 12 can be mounted on the first spindle 8 and / or the second spindle 9 at winding positions W.1 to Wn. A guide track 4 is positioned above and spaced apart from the spindles 8, 9, and a number of yarn guides 40 can be guided on this guide track 4.

[0035] The first spindle 8 shown in FIG. 1 is positioned in a winding position where a composite filament bundle is wound onto a bobbin 12 to form a package 14 .

[0036] The second spindle 9 is positioned in a doffing position where the finished package 14 may be removed from the spindle.

[0037] The positions of the first spindle 8 and the second spindle 9 may be changed from the winding position to the doffing position and vice versa by a spindle revolver (not shown). Below, the invention will be described with reference to the first spindle in the winding position, as also shown in the drawings.

[0038] The guide track 4 has a first track section 43 in which a number of thread guides are stored and a third track section 45 in which a number of thread guides are distributed in winding positions. The first track section 43 extends substantially perpendicularly to the third track section 45 in a direction away from the spindle (see also Figures 3 and 4, which show the storage position P of the thread guides in the guide track, and Figures 5 and 6, which show the installation position of the thread guides in the guide track).

[0039] For example, as shown in detail in Figures 3 and 5, the guide track 4 has a second track section 44 connecting the first track section 43 and the third track section 45 such that the first track section 43 is at an angle to facilitate movement of the yarn guide 40 from the storage position P to the winding positions W1 to Wn.

[0040] In a further embodiment, the thread guides 40 are movable between a storage position P and a rigging position A, for example as shown in Figures 3 and 4. In the storage position P, the thread guides are positioned substantially adjacent to one another, as shown in Figures 2 and 3, whereas in the rigging position, the thread guides are spaced apart, as shown in Figures 1 and 2 or 4 and 5.

[0041] FIG. 7 shows a plan view of the guide track 4 in a detailed view.

[0042] The third track section 45 extends in a first plane substantially parallel to and spaced apart from the first spindle 8 or the second spindle 9 and is inclined in a second plane at a guide track inclination angle α, so that one end section of the third track section 45 positioned adjacent the second godet 22 has a greater distance from the spindle 8, 9 than the other end section of the third track section 45 inclined towards the spindle 8, 9.

[0043] With continued reference to Figures 1 and 7.

[0044] The yarn guide 40 is mounted on a yarn guide holder 41 which is movable along a guide track 4. The distance between the yarn guide holder 41 and the guide track 4 increases with each winding position. The distance between the guide track 4 and the yarn guide holder 41 is largest at the first winding position W1 and smallest at the n-th winding position Wn, thereby enabling each yarn guide holder 40 to grip the yarn bundle F. The guide track is inclined at a guide track inclination angle α with respect to the winding spindles 8, 9, as shown in FIG. 7.

[0045] The yarn guide holder 41 has a yarn catcher 42 at the end section opposite the guide track 4, by means of which one filament bundle F is caught for each winding position and fixed in position during movement along the guide track 4.

[0046] The yarn bundles F are gathered together by the supply suction gun 26 during rigging at the winding position, which allows each yarn bundle F from the yarn guide 40 to be captured as it moves to the rigging position A.

[0047] The winding device 1 comprises a godet support 2 having a first godet 21 and a second godet 22, between which a movable take-up roller for taking up the filament bundle F is positioned.

[0048] The winding device 1 has a first spindle 8 equipped with a first spindle drive 18 and a second spindle 9 equipped with a second spindle drive 19, and the first spindle 8 and the second spindle 9 are each movable between a winding position for winding to form a package 14 and a doffing position for removing the package 14.

[0049] By incorporating a guide track 4 with three track sections 43, 44, 45 and positioning the guide track 4 above and spaced apart from the spindles 8, 9, the present invention allows for automatic feeding of the filament bundle F or yarn to the winding device 1, thereby eliminating limitations of the prior art and improving the overall efficiency of the winding process.

[0050] The present invention allows for automatic distribution and winding of the filament bundle F onto the winding tube 12, with the yarn guide 40 moving along a specially designed guide track 4, which ensures efficient and accurate winding and improves automatic setup. [Explanation of symbols]
