Device for wetting a running thread

The invention relates to a device for wetting a running thread according to the preamble of claim 1.

In the manufacture and treatment of multifilament synthetic threads, it is generally known that the thread is wetted with a fluid. The fluid, which preferably consists of a water-oil mixture, serves to make the friction between the thread and guide elements so gentle that no breaks occur on the individual filaments of the multifilament thread. In addition, the fluid is used in particular in a manufacturing process to ensure the cohesion of the individual filaments within the thread. In order to be able to adequately fulfill these functions on the thread, the fluid must be applied to the thread as evenly as possible. Basically, however, there is the problem that excess fluid that is not accepted by the thread drips off or is thrown off by the thread. Therefore, the fluid is fed to the thread in such small amounts that the amount of the fluid is absorbed and adheres to the thread. However, it is important to ensure that the amount of fluid supplied is sufficient to wet all filaments of the thread. Maintaining this balance between overdosing and insufficient wetting proves to be particularly critical, especially with fast-running threads, since the dynamics of the thread make the absorption of the fluid even more difficult.

In order to obtain longer contact times for wetting the thread, in particular at high thread speeds, it is therefore known to guide the thread with a loop on a rotatable wetting ring which has a wetted thread running track on the circumference. Such a generic device is described for example in DE 102 18 748 A1.

In the known device for wetting a running thread

Thread track formed by a porous insert. The porous insert is integrated in the wetting ring in such a way that the insert on the inside of the wetting ring can be wetted with a fluid. The porous insert is thus continuously wetted from the inside, the fluid reaching the surface of the insert through the capillary with centrifugal assistance. Thus, the fluid passes over the entire circumference of the

BE2017 / 5135

Wetting on the surface. However, since the thread on the wetting insert is only guided with a partial wrap, it is hardly possible to meter and evenly apply it to the thread.

It is therefore an object of the invention to further develop the generic device for wetting a running thread in such a way that a metered delivery of the fluid through the wetted thread running track is possible.

This object is achieved according to the invention in that the thread running track has a plurality of radial bores which are evenly spaced around the circumference of the thread running track and which alternately interact with the nozzle opening when the wetting ring rotates.

Advantageous developments of the invention are due to the features and

Characteristic combinations of the subclaims defined.

The devices known in the prior art for wetting a running thread are based on the thread being brought continuously into contact with a fluid.

This ensures that at least one underside of the thread is continuously wetted.

In this respect, the inventor first had to overcome the reservation that the fluid should not be fed continuously but discontinuously to the thread. In the device according to the invention, the fluid is guided over the radial bores on the surface of the thread running track. The radial bores alternately interact with a nozzle opening of the stationary fluid nozzle. The fluid is thus fed to the thread in discontinuous fluid flows.

However, it has been shown that the extension of the contact times, which is achieved by the thread being wrapped around the wetting ring, results in a distribution of the fluid within the thread that is essentially caused by the centrifugal force. In this respect, both the amount of discharge at the radial bore can be dimensioned such that there is a uniform distribution and an even application of the fluid when the thread is left.

In order to obtain a defined distribution of the filaments of the filament bundle, it is further provided that the thread running track on the circumference of the wetting ring

BE2017 / 5135 a circumferential wetting groove is formed, the radial bores being formed in a groove base of the wetting groove. Depending on the groove width of the groove base, the

Filaments of the filament bundle are thus guided one above the other in a few layers.

In addition, a safe guidance of the thread on the circumference of the wetting ring is possible.

In order to generate a recurring, uniform fluid flow via the radial bores, the development of the invention is particularly suitable, in which a metering pump is assigned to the fluid distributor, the metering pump being connected to the fluid nozzle via a pressure line. This enables a uniform supply of the fluid and in particular a uniform pulsed delivery of the fluid. In addition, additional pressure settings of the metering pump can be used to change the volume flow at the fluid.

In order to enable the thread to be guided without friction, the further development of the invention is preferably carried out, in which the wetting ring is coupled to a drive, by means of which the wetting ring can be driven in a thread running direction.

The wetting ring is preferably driven by the drive at a circumferential speed which is equal to a thread entry speed. In this way, the metering of the fluid on the thread can be further improved.

In a simple embodiment, the wetting ring is connected on one end face to a drive shaft of the drive by a carrier wall. For example, a motor shaft of an electric drive could be used directly to drive the wetting ring.

To at yarn speeds in the range of 2,000 to 3,000 m / min. To obtain a sufficient contact time in the case of partial wrap around the wetting ring, the development of the invention is particularly advantageous in which the thread running track on the circumference of the wetting ring has an outside diameter in the range from 20 mm to 120 mm, preferably in the range from 40 mm to 80 mm. Depending on the thread titer, the contact times required for wetting the thread can be achieved.

To guide the thread, it must be ensured that there is constant contact between the thread and the thread running track. For this is the extent of the thread track

BE2017 / 5135 a guide bar with a bar width of at least 0.5 mm is formed between adjacent radial bores.

This is sufficient even with larger bridge widths and larger thread titers

If the amount of fluid can be provided per radial bore, it is further provided that the radial bores have a constant bore diameter in the range from 0.5 mm to 2 mm at the circumference of the thread running track. In this way, an equal volume flow is generated on the fluid through each of the radial bores. Due to the larger bore diameters, the fluid quantities in particular can be adapted to the overall titer of the thread.

The fluid is preferably supplied in accordance with the development of the invention, in which the distributor is a stator which is formed in the interior of the wetting ring and which forms a sealing gap with the wetting ring in the region of the nozzle opening. This avoids loss of fluid. To support the sealing gap, there is also the possibility of arranging additional seals on the stator with respect to the wetting ring.

It is fundamentally possible for a plurality of thread running tracks formed parallel to one another to be provided on the wetting ring in order to prepare a plurality of threads at the same time. The guidance of the wetting ring can also be stabilized in that the stator has an outer guide surface which interacts with an inner running surface of the wetting ring. In this way, a plurality of threads can also be wetted simultaneously by a driven wetting ring with several thread running tracks.

For shielding, it is also provided that the wetting ring is assigned a cover in the area of the thread running track, which cover forms a thread inlet and a thread outlet for guiding a thread on the thread running track with a loop of approximately 180 °. In particular, the environment can be kept free of volatile components of fluid wetting. To support this, there is also the option of combining the cover with a suction device, so that volatile constituents are sucked out of the area surrounding the thread.

In order to treat a thread with different fluids, the development of the invention is particularly advantageous in which the wetting ring has several inside

BE2017 / 5135

Fluid nozzles are assigned with separate nozzle openings which are formed one behind the other in the circumferential direction. So there is the possibility of threading several

Treat areas with a supplied fluid. In this case, identical fluids can be applied to the thread several times or different fluids can be fed to the thread in succession.

To this extent, the fluid nozzles on the fluid distributor can be connected to one or more fluid sources. For example, a thread can be wetted with an identical fluid if it is supplied jointly by a fluid source. When connecting the fluid nozzles to several fluid sources, different fluids can be supplied to the thread for wetting. In this case, however, gaseous fluids can also be used in order to improve the distribution of the fluid on the thread by means of an air stream during prewetting.

The device according to the invention for wetting a running thread is thus particularly suitable for carrying out a uniform and metered wetting on the thread at higher thread running speeds.

The invention is described below with reference to an embodiment of the device according to the invention for wetting a running thread with reference to the accompanying figures.

They represent:

1 and 2, a first embodiment of the device according to the invention for wetting a running thread is shown in several views. Fig. 1 shows

BE2017 / 5135 schematically shows a longitudinal sectional view and in Fig. 2 is a cross sectional view of the

Embodiment shown. The following description applies to both figures, insofar as no express reference is made to one of the figures.

The exemplary embodiment of the device according to the invention for wetting a running thread has a wetting ring 1 which is held rotatably. The wetting ring 1 is formed on the outer circumference with a circumferential thread track 2. The thread running track 2 forms a contact area on the wetting ring 1, on which a thread with a partial wrap can be guided. A large number of radial bores 5, which penetrate the wetting ring 1 up to an inner side, are assigned to the thread running track 2.

In this exemplary embodiment, the thread track 2 is designed as a wetting groove 8, the radial bores 5 being arranged in the groove base 9. At this point, however, it has been expressly mentioned that the thread running track 2 could also be formed on an insert which is integrated in the wetting ring 1. For example, the wetting ring 1 could be made of a metallic material and an insert for forming the thread running track 2 could be made of a ceramic, wear-resistant material.

Regardless of the structural design of the thread running track, the arrangement and design of the radial bores 5 is essential, which enables a connection for supplying fluid to the outer surface of the thread running track 2.

For this purpose, a fluid distributor 3 is arranged in the interior of the wetting ring 1, which in a fixed position has a fluid nozzle 4 with a nozzle opening 6 facing the wetting ring 1. In this exemplary embodiment, the fluid distributor 3 is formed by a fixed stator 12 which extends with an outer guide surface 13 over a partial circumference in the interior of the wetting ring 1. The wetting ring 1 forms an inner running surface 14 which cooperates with the guide surface 13 of the stator 12 to form a sealing gap 7.

The fluid nozzle 4 is connected to a fluid source 10 via a plurality of pressure lines 11, the fluid source 10 being supplied with a fluid for wetting a multifilament thread, for example an oil-water emulsion, via a metering pump.

BE2017 / 5135

The fluid nozzle 4 with the nozzle opening 6 and the radial bores 5 in the thread track 2 lie in a common plane, so that with a rotation of the wetting ring 1, the radial bores 5 alternately interact with the nozzle opening 6 of the fluid nozzle 4.

As can be seen in particular from the illustration in FIG. 1, the wetting ring 1 is held via a carrier wall 15 which is connected to a drive shaft 16 in a rotational test by means of a hub 17. The drive shaft 16 is connected to a drive, not shown here, for example an electric motor. For example, the drive shaft 16 could be designed directly as a motor shaft of an electric motor.

As can be seen from the illustrations in FIGS. 1 and 2, the wetting ring 1 is encased at a distance by a cover 18. The cover 18 has an inlet opening 21 and an outlet opening 22 on both sides of the wetting ring 11. In this case, the inlet opening 21 and the outlet opening 22 are designed such that a thread fed through the inlet opening 21 can be guided with a wrap angle of 180 ° on the thread running track 2 of the wetting ring 1. The thread path is shown in Fig. 2.

As can be seen from the illustration in FIG. 1, the cover 18 has a lower one

Area a collecting groove 19 which is connected to a drain 20. In this way, the fluid released from the area surrounding the thread can be collected and discharged. The drain 20 could also be coupled to a suction device, so that the surroundings are sucked off to the wetting groove 8 for receiving the volatile constituents.

The embodiment of the device according to the invention according to FIGS. 1 and 2 is suitable for wetting multifilament threads which have previously been spun in a melt spinning process and at higher speeds in the range of 1,000 m / min. up to 3,000 m / min. be performed. The wetting ring 1 is driven by the drive shaft 16 at a peripheral speed which is equal to a thread feed speed. Thus, the thread is fed via the inlet opening 21 and guided in contact with the wetting groove 8 in the groove base 9. The fluid nozzle 4 of the fluid distributor 3 is arranged in the feed region of the thread, so that a fluid supplied via the metering pump 10 to the fluid nozzle 4 is held under pressure. As soon as one of the radial bores 5 of the wetting ring 1 enters the opening area of the nozzle opening 6 of the fluid nozzle 4,

BE2017 / 5135, a brief volume flow of the fluid is applied via the radial bore 5 to the thread guided in the groove base 9. As the wetting ring 1 continues to move, the nozzle opening 6 is closed by a web 23 formed between adjacent radial bores 5. Only when the adjacent radial bore 5 has been reached can a new fluid stream be briefly fed to the thread. To this extent, the thread in the groove base 9 of the wetting groove 8 receives a discontinuously supplied fluid application.

In the further course, the amount of liquid dispensed per radial bore 5 is distributed in the thread. The multifilament thread thus consists of a large number of individual filament strands which are guided in several layers on the bottom 9 of the groove. Due to the peripheral speed of the wetting ring 1, a centrifugal force acts on the liquid particles, so that the filament bundle of the thread is penetrated by the fluid during the contact time on the periphery of the thread running track 2. Depending on the amount of fluid and depending on the number of radial bores 5 on the circumference of the thread running track 2, very evenly distributed fluid orders can thus be generated on the thread.

In Fig. 3 are for illustration the geometric parameters that the

Determine fluid application significantly, shown schematically. 3 shows a cross-sectional view of the wetting ring 1 in the region of the fluid nozzle 4 in a partial section. The bore diameter of the radial bores 5 is shown with the code letter d and the guide web 23 formed between adjacent radial bores 5 is shown with a web width s. Both the bore diameter d of the radial bores 5 and the web width s of the guide web 23 are of the same size on the circumference of the wetting groove 8 in this exemplary embodiment. In this respect, a uniform discontinuous fluid flow is generated at a constant peripheral speed of the wetting ring 1. The guide web 23 has a minimum web width s of 0.5 mm, so that a reliable guidance of the thread is guaranteed. Depending on the thread titer and depending on the number of filaments in the thread, the radial bores have a bore diameter d in the range from 0.5 mm to 2 mm. In order to obtain special effects during wetting, the bore diameter d of the radial bore 5 and the web width s of the guide webs 23 can be designed with different sizes on the groove base of the wetting groove 8.

BE2017 / 5135

The thread running track 2 determines the contact time of the thread, which can be used for the distribution of the fluid, with an outer diameter and the predetermined looping area. In the embodiment shown in FIG. 2, an outer diameter of the groove base 9 of the wetting groove 8 is decisive for this. In Fig. 2, the outer diameter is marked with the letter D. Depending on the thread titer of the thread and depending on the thread feed speed, the outer diameter D of the thread running track 2 can be in the range from 20 mm to 120 mm, preferably in the range from 40 mm to 80 mm. In this respect, the device according to the invention is suitable for wetting all common synthetic threads.

In the embodiment shown in Fig. 2, the thread with a

Wrap angle of 180 °. For this purpose, the inlet opening 21 and the outlet opening 22 are formed on the cover 18 offset by 180 °. This version is exemplary. Basically, the thread can be made with a smaller or larger

Wrapping the thread track 2 of the wetting ring 1 are performed.

A further exemplary embodiment of the device for wetting a thread according to the invention is shown schematically in a cross-sectional view. The embodiment according to FIG. 4 is essentially identical to the aforementioned embodiment according to FIGS. 1 and 2, so that only the differences are explained at this point and otherwise reference is made to the aforementioned description.

In the exemplary embodiment shown in FIG. 4, two fluid nozzles 4.1 and 4.2, each with a nozzle opening 6.1 and 6.2, are assigned to the wetting ring 1 on the inside of the stator 12. The fluid nozzles 4.1 and 4.2 are formed one behind the other in the circumferential direction of the wetting ring 1 in one plane in the direction of rotation of the wetting ring 1. The mouth area of the nozzle openings 6.1 and 6.2 lies in the wrapping area of the thread track 2 formed on the outer circumference of the wetting ring 1. The thread track 2 is also formed in this case by the wetting groove 8, which has a plurality of radial bores 5 in its groove base 9. To this extent, by rotating the wetting ring 1, each of the radial bores 5 can alternately be connected to both nozzle openings 6.1 and 6.2 of the fluid nozzles 4.1 and 4.2.

The fluid nozzles 4.1 and 4.2 are connected together via a plurality of pressure lines 11 to a fluid source (not shown here). For example, the one shown in FIG

BE2017 / 5135

Dosing pump 10 with an associated fluid tank can be used as a fluid source for the two fluid nozzles 4.1 and 4.2.

The function of the embodiment shown in FIG. 4 is identical to the previous embodiment. Thus, the wetting ring 1 is preferably driven by an electric motor in order to dispense a quantity of fluid into the wetting groove 8 in the wrap-around area of the wetting groove 8 via the fluid nozzles 4.1 and 4.2 at the point in time at which the radial bores 5 communicate with the nozzle openings 6.1 and 6.2. The thread is thus wetted several times as it passes through the wetting groove 8.

In principle, however, there is also the possibility that the fluid nozzles 6.1 and 6.2 are connected to separate fluid sources. 5 and 6, a further embodiment of the device according to the invention is shown. 5 shows the embodiment in a longitudinal sectional view and in FIG. 6 in a cross-sectional view. 5 and 6 is essentially identical to the aforementioned embodiment, so that the parts with the same function have been given the same reference numerals and so that reference is made to the above description at this point and only the differences are explained.

The following description applies to both figures, insofar as no express reference is made to one of the figures.

In the embodiment shown in FIGS. 5 and 6, a plurality of fluid nozzles 4.1 and 4.2 are formed on the fluid distributor 3, each of which has a nozzle opening 6.1 and 6.2. The nozzle openings 6.1 and 6.2 are arranged on the stator 12 and held stationary. The stator 12 is enclosed by the rotatable wetting ring 1 with a sealing gap 7. A wetting groove 8 is formed on the wetting ring 1 and has a multiplicity of radial bores 5 in the groove base 9. The radial bores 5 alternate in the area of the nozzle openings 6.1 and 6.2, so that the fluid nozzles 4.1 and 4.2 can each deliver a fluid flow into the wetting groove 8.

The fluid nozzles 4.1 and 4.2 are coupled to two separate fluid sources 10.1 and 10.2 via separate pressure lines 11.1 and 11.2. In this case, the fluid sources 10.1 and 10.2 are also designed as metering pumps with a fluid tank.

BE2017 / 5135

In operation, a thread guided in the groove base 9 of the wetting groove 8 can be treated with different fluids through the fluid nozzles 4.1 and 4.2. There is also the possibility that the downstream one on the wetting ring

Fluid nozzle 4.2 is used to generate an air flow. Such a gaseous fluid enables an equalization of the wetting order previously generated on the thread. In such a case, the fluid source could be a compressor or an air conditioner for generating a cold or warm air flow.

Regardless of the type of fluid, the device according to the invention is particularly suitable for wetting any type of thread.
