Description

FIELD OF THE INVENTION

The invention relates to an arrangement for guiding a running thread. The invention further relates to a unit with such an arrangement, as well as a method for guiding a running thread.

TECHNICAL BACKGROUND

Although the present invention may be useful and advantageous in connection with the guiding of a thread or yarn in connection with many types of units or devices which serve to process the thread or yarn, the invention and the problem underlying it explained in more detail below using the example of an input thread guide for a texturing unit.

It is known to provide a roller-shaped thread guide at the entrance of a texturing unit, via which the thread is guided into the unit. In the texturing unit, the thread or yarn is then texturized by discs, in other words, the thread or yarn is "twisted" to create crimp and elasticity.

Conventional input thread guides for texturing units, for example, are rigidly mounted in order to build up the tension necessary for the texturing process.

It has now been shown that - especially with abrasive threads/yarns - the surface of the input thread guide is heavily loaded, causing it to wear out relatively quickly. This can be particularly the case with threads or yarns that are often already spun in a dyed manner. Conventional thread guides that are rigidly mounted during operation therefore often have to be turned into a different position within a few days or weeks in order to bring a different point on the input thread guide into contact with the thread. For this it is necessary to stop the machine and thus the manufacturing process. After a few such twisting processes, the thread guide is completely worn out and must be replaced.

A number of approaches have already been proposed to increase the service life of the input thread guide by selecting a suitable ceramic or coatings. For example, in the article "Manufacturers of spun-dyed yarns profit from innovative micro-components" in the trade journal "Fibers and Filaments" (Barmag Magazine), September 2015 issue, a coating was mentioned that is intended to significantly increase the service life of an input thread guide.

However, it would be desirable to be able to use a thread guide over a long period of use, in particular without damaging the thread or yarn being guided, without necessarily requiring a complex coating or a particularly expensive material. It would also be desirable to further improve the service life of a thread guide compared to conventional designs.

The document US 3,766,726 discloses an assembly including an arm 23 having a thread guide E (see Figures 1-3).

SUMMARY OF THE INVENTION

Against this background, the invention is based on the object of specifying a correspondingly improved arrangement for guiding a running thread. Furthermore, an improved unit for processing or processing a thread and an improved method for guiding a running thread are to be specified.

This problem is solved according to some aspects of the invention with an arrangement with the features of patent claim 1 and/or with an aggregate with the features of patent claim 9 and/or with a method with the features of patent claim 10.

According to one aspect of the invention, an arrangement for guiding a running thread is proposed, the arrangement having a thread guide which is arranged such that the thread guide is movable while guiding the thread.

According to a further aspect of the invention, an aggregate for processing or processing a thread is also proposed, the aggregate having such an arrangement.

In addition, according to a further aspect of the invention, a method for guiding a running thread by means of a thread guide is proposed. In the process, the thread guide is moved while guiding the thread, or a movement of the thread guide is influenced while guiding the thread.

One idea of the present invention is that severe wear of the thread guide, and the resulting damage to the thread or yarn, can be effectively avoided or at least reduced if the thread guide moves while guiding the thread and thus the effect the thread friction is distributed over a large number of places, for example the entire circumference of the thread guide, and the yarn or thread does not only run over a single point on the thread guide. Excessive local heating of the thread guide and resulting local damage to it can be avoided in this way. By moving the thread guide while guiding the thread or allowing a movement of the thread guide and influencing the movement of the thread guide while guiding the thread, the frictional forces are distributed over the effective surface of the thread guide without it being necessary to use the machine or to stop the unit in which the thread guide is inserted. For this purpose, the thread guide can, for example, be mounted in a suitable movable manner, for example directly or via another element. This means that particularly complex and expensive coatings on the thread guide can be dispensed with, although if necessary, a coated thread guide can also be used in the present invention.

Advantageous refinements and further developments result from the subclaims and from the description with reference to the figures in the drawing.

According to one aspect of the invention, the arrangement is designed to guide a running thread into a texturing unit, wherein the thread guide is designed as an input thread guide and is designed to guide the thread to be texturized into the texturing unit.

According to one aspect of the method, the thread is a thread to be texturized, which is guided into a texturing unit. Here, the thread guide is designed as an input thread guide, and the thread is guided into the texturing unit by means of the input thread guide. According to this aspect of the invention, the method is therefore a method for guiding the running thread into the texturing unit.

For example, the input thread guide for a texturing unit is exposed to considerable stress, especially with abrasive yarns. The invention is therefore not only applicable to input thread guides at the entrance of texturing units, but is particularly advantageous in the case of such an input thread guide, since the invention succeeds in significantly reducing the wear that occurs and thereby significantly increasing the service life of such a highly loaded input thread guide . This improves the process qualitatively and quantitatively.

Alternatively, according to a further aspect of the invention, the arrangement can be designed for guiding a thread to be texturized out of a texturing unit and the thread guide can be designed as an output thread guide and set up to guide the thread out of the texturing unit.

Furthermore, according to a further aspect of the method, the thread can be a thread to be texturized, which is guided into a texturing unit, the thread guide being designed as an output thread guide and the thread being guided out of the texturing unit by means of the output thread guide.

If reference is made to the thread guide in the aspects, refinements and developments of the invention explained below, this term can always, unless stated otherwise, refer in particular to the input thread guide mentioned above or to the output thread guide mentioned above, in other words, a Application to the input and/or the output thread guide is conceivable.

According to one aspect of the invention, the thread guide can be driven to move it while guiding the thread. According to one aspect of the method, the thread guide is driven while guiding the thread and is thereby moved in a predefined or defined manner.

A predefined or defined adjustable or set movement should be understood in particular to mean that, for example, the speed of movement and/or direction of movement can be predefined and thus predetermined. However, for example, the speed of movement and/or direction of movement can instead be varied and, in this sense, adjustable in a defined manner. The defined setting of the movement of the thread guide can thus be carried out in the present case in particular by, for example, manual selection or presetting, by control and/or by regulation.

A defined movement of the thread guide caused by a targeted drive can have an advantageous effect on the machining/processing process to be carried out, in particular on the texturing of the thread. In particular, with the help of a defined movement speed of the thread guide, both suitable thread tension and reduced wear on the thread guide can be achieved.

According to one embodiment of the arrangement, the movement of the thread guide can be controlled or regulated. According to this embodiment, the arrangement has one device, or several devices, by means of which the controlled or regulated mobility of the thread guide is possible. In one embodiment of the method, the thread guide is moved in a controlled or regulated manner while the thread is being guided, or a movement of the thread guide is specifically influenced to control or regulate the movement. In addition to an effective reduction in wear on the thread guide, the targeted Controlling or regulating the movement of the thread guide, the process of thread processing or thread processing can be influenced or controlled in a more detailed manner. In particular, if the thread guide is the input thread guide and/or output thread guide of a texturing unit, a controlled or regulated movement of the thread guide, or a targeted, controlled or regulated influence on the movement of the thread guide, can open up further additional possibilities for the operation. or to influence the processing process for the thread or yarn in an expanded manner. This allows an operator to have additional setting options for the overall device or machine being used.

In one embodiment of the arrangement, the thread guide can be rotated about at least one axis of the thread guide to provide mobility. In a preferred variant, the thread guide can be mounted for rotation about exactly one axis, in other words for uniaxial rotation. In further, alternative and also conceivable embodiments, the thread guide can be mounted rotatably about several axes. With the help of rotatability, a movement of the thread guide can be made possible in a relatively simple manner, with uniaxial rotatability in particular being advantageously easy to implement and still enabling an effective reduction in wear.

In one embodiment of the method, a rotational movement of the thread guide is brought about while the thread is being guided, or a rotational movement of the thread guide is specifically influenced while guiding the thread. In a preferred variant, the thread guide rotates about exactly one axis. Inducing or influencing the movement is relatively easy.

In a further embodiment, the thread guide can be displaceable to provide mobility. In particular, to provide mobility, the thread guide can be linearly displaceable, for example axially displaceable, in other words, displaceable along an axis of rotation of the thread guide. The thread guide can also be provided with mobility in a relatively simple manner through displaceability, in particular linear displaceability. In further embodiments, the thread guide can be displaced, in particular linearly, in several directions.

According to one embodiment of the method, the thread guide is set into a displacement movement while guiding the thread, or a displacement movement of the thread guide is specifically influenced while guiding the thread. The displacement movement can in particular be a linear, for example axial, displacement movement of the thread guide. In this way, too, the movement of the thread guide can be provided or influenced in a relatively simple manner.

In a further embodiment, the thread guide is mounted so that it can rotate about one or more axes and can be displaced along one or more directions.

This allows for the provision of multiple degrees of freedom of movement. This can be achieved in a particularly simple manner, for example, if the thread guide can be rotated about its axis of rotation and can also be displaced axially, i.e. along the axis of rotation.

In further embodiments of the method, the thread guide can be set into one or more rotational movements while guiding the thread, or one or more rotational movements of the thread guide can be specifically influenced while guiding the thread. Additionally or alternatively, in this embodiment, the thread guide can be set into one or more displacement movements while guiding the thread, or one or more displacement movements of the thread guide can be specifically influenced. In particular, in such configurations, rotational movements of the thread guide about one or more axes and/or displacement movements of the thread guide along one or more directions can be brought about or influenced in a targeted manner while guiding the thread.

According to variants of the invention, it can be provided that, instead of several movements, the thread guide only carries out a rotational movement about exactly one axis or a displacement movement parallel to exactly one direction and is arranged accordingly.

In embodiments of the invention, the thread guide can in particular be mounted on roller bearings, for example by needle bearings or ball bearings or roller bearings. In other embodiments, the thread guide can be magnetically mounted, in other words, storage occurs with the help of a magnetic field. In further embodiments, the thread guide can be air-supported, in other words, the storage takes place with the help of air, e.g. B. by generating excess pressure and/or a flow between bearing surfaces. In yet other embodiments, the thread guide can be slide-mounted, with, for example, slide bearings, slide bushings or sliding coatings being provided, which enable sliding storage with tolerable friction and tolerable wear.

In one embodiment, the thread guide can be driven to rotate the thread guide about an axis of rotation thereof, in particular for a rotation about exactly one axis of rotation. A rotary drive of the thread guide can be achieved in a relatively simple and reliable manner.

In one embodiment of the method, the thread guide is driven in such a way that the thread guide rotates about an axis of rotation of the thread guide, in particular about exactly one axis of rotation, while guiding the thread. In other words, in this embodiment, the thread guide is driven for a uniaxial rotational movement, with the aforementioned advantages.

In one embodiment, the axis of rotation of the thread guide is arranged transversely to a thread running direction of the thread, in particular when the thread guide can be rotated in one axis.

In one embodiment, the thread guide can be designed to be roller-shaped. Due to its symmetry properties, such a thread guide can prove to be particularly advantageous when the thread guide carries out a rotary movement. However, a roller-shaped design of the thread guide is not absolutely necessary, and in alternative and advantageous embodiments of the invention the thread guide can be designed other than roller-shaped.

In one embodiment, the thread guide has a circumferential groove on its circumference for guiding the thread, with a base of the groove being particularly rounded. In particular, the thread can thus slide under the desired thread tension over the rounded base of the groove of the thread guide without being clamped and held by the thread guide. In particular, different groove cross sections are also conceivable, which prevent the thread from getting stuck.

In one embodiment, the arrangement can have a drive device which is coupled to the thread guide in such a way that the thread guide can be driven and set in motion by means of the drive device. In this embodiment, the movement of the thread guide, for example a rotary movement, a displacement movement or a combination thereof, can be brought about in a targeted manner by means of the drive device. According to one embodiment of the method, the thread guide is driven by a drive device. In particular, the thread guide can be driven by means of the drive device for the rotary movement thereof.

In one embodiment, the drive device has a motor, in particular an electric motor, or is designed as such a motor. With this configuration, a targeted movement of the thread guide can be brought about in an expedient manner and can be controlled or regulated well.

In one embodiment, a movement speed or a movement direction of the thread guide or both can be adjustable in accordance with a predefined, constantly selected value. With a corresponding embodiment of the method, the speed of movement and/or the direction of movement of the thread guide are each set constant. For example, a rotational speed of the thread guide can thus be set to a constant value. Additionally or alternatively, a direction of rotation of the thread guide can be set to be constant.

In one embodiment, the speed of movement and/or the direction of movement of the thread guide are determined depending on the operating parameters of the texturing unit. This can be done, for example, by having a speed of the thread guide in a fixed relationship to a speed of an element of the texturing unit. Alternatively or additionally, the direction of rotation of the thread guide can be in a fixed relationship to the direction of rotation of the element of the texturing unit.

In a further embodiment of the arrangement, a movement speed and/or a movement direction of the thread guide can be controllable or regulated. In one embodiment of the method, a movement speed and/or a movement direction of the thread guide is/are controlled or regulated.

According to a further development of the arrangement, in particular a rotation speed and/or a direction of rotation can be controlled and/or regulated. If a displacement movement is provided, a displacement speed and/or a displacement direction can additionally or alternatively be controllable or regulated. Preferably, the rotational speed and/or the displacement speed can each be continuously controlled or regulated. In this way, an even more detailed, targeted, and precise influence on the processing or processing process for the thread is possible. This opens up additional adjustment options for the machine operator when processing the thread or yarn and makes it possible to prevent wear on the thread guide and thus damage to the thread or yarn that can be caused by such wear as effectively as possible.

In a corresponding embodiment of the method, a rotation speed and/or a direction of rotation can be controlled or regulated. If a displacement movement is provided, a displacement speed and/or a displacement direction of the thread guide can alternatively or additionally be controlled or regulated.

In one embodiment, the drive device, in particular the motor, for example the electric motor, is speed-controlled. For this purpose, the drive device can be coupled, for example, to a frequency converter. However, if control of the speed of the drive device is not desired, the frequency converter can be omitted.

In one embodiment, the thread guide is driven in such a way that the thread guide rotates at a substantially constant speed while guiding the thread.

By way of example, the speed of the thread guide, in particular if it is designed as an input thread guide for the texturing unit, can be in a range from approximately 5 revolutions per minute to approximately 20 revolutions per minute, in particular in a range from approximately 8 revolutions per minute to approximately 10 revolutions per minute Minute, lie. In this way, an effective reduction in wear on the thread guide can be achieved.

However, the invention is not limited to such a choice of speed, but the thread guide can be driven for a rotational movement at speeds outside the aforementioned exemplary ranges, for example at significantly higher speeds than mentioned above, which also has advantages in terms of reducing wear on the thread guide can be achieved.

In the present invention, the thread guide is driven in such a way that a running speed of the thread and a peripheral speed of the thread guide differ in a contact area of the thread with the thread guide. As a result, the running thread slides over a guide surface of the thread guide when it is guided. The thread is therefore not held by the thread guide, but rather a thread tension that is conducive to the processing or processing process, such as texturing, is created.

In one embodiment of the method, mechanical power for driving the thread guide, in particular the input thread guide, is tapped from a rotating element of the texturing unit, in particular from a rotating shaft of the texturing unit. With a corresponding design of the arrangement, the arrangement is designed for such tapping of mechanical power. A separate motor drive for the thread guide is unnecessary. A fixed ratio of the speed of the thread guide to the speed of the rotating element of the texturing unit, for example, can be achieved in a structurally simple manner.

For example, in a further development, the mechanical power for driving the thread guide, in particular the input thread guide, can be tapped from a rotating shaft of the texturing unit, which carries at least one texturing disk for texturing the thread. In a corresponding further development, the arrangement can be designed for this purpose. However, can In an alternative development, an additional shaft can be provided as a rotating element of the texturing unit, which does not carry a texturing disk, the aforementioned mechanical power for driving the thread guide being tapped in this case by the additional shaft of the texturing unit.

In a further development, the arrangement can have a gearbox coupled to the thread guide, in particular the input thread guide, by means of which a speed picked up by the rotating element of the texturing unit and a torque picked up by the rotating element of the texturing unit can be converted into a gearbox output speed and a gearbox output torque for driving of the thread guide can be changed.

The transmission can in particular be designed as a mechanical transmission, such as a gear transmission. For example, the transmission can be designed with an angular gear, such as a bevel gear. Alternatively, however, other types of transmission are also conceivable, such as a friction wheel transmission.

In particular, the transmission has at least one gear reduction, by means of which the speed of the rotating element of the texturing unit can be reduced to the transmission output speed intended for driving the thread guide. When tapping mechanical power, for example from a shaft that carries one or more texturing disks, the high speed present on the shaft can be increased from, for example, between approximately 10,000 and approximately 12,000 revolutions/minute to the desired one The speed of the thread guide can be reduced. If necessary, this can happen in several stages, for example. If mechanical power is tapped from a shaft without texturing disks, its speed can, for example, be reduced in a corresponding manner to the gearbox output speed intended to drive the thread guide.

In a further embodiment of the invention, the mechanical power for driving the thread guide is picked up by friction from the rotating element of the texturing unit. In an alternative embodiment of the invention, the mechanical power for driving the thread guide could be tapped by positively coupling the gear with the rotating element of the texturing unit.

According to another embodiment, the arrangement has a braking device which is coupled to the thread guide in such a way that a movement of the thread guide can be braked by means of the braking device. Again, the movement can be a rotational movement or a sliding movement or a combination thereof. In this embodiment, the thread guide can in particular initially be freely movable, i.e. freely rotatable and/or freely displaceable, stored in such a way that the thread guide is driven by the thread, for example to achieve its rotational movement. With the help of the braking device, the movement or movements of the thread guide can then be specifically influenced while guiding the running thread in order to control or regulate the movement(s) of the thread guide.

In one embodiment of the method, the thread guide is driven by the running thread and braked by means of a braking device. With this embodiment of the method, too, a targeted influence on the movement or movements of the thread guide can advantageously be achieved by means of the braking device.

According to a further development, the braking device is designed to brake the thread guide mechanically and/or electrically and/or magnetically and/or with the aid of a medium. If a medium is used, the medium can be, for example, a fluid, for example a gas or a liquid.

According to one embodiment, energy is used for moving the thread guide and/or for influencing the movement of the thread guide and/or for controlling or regulating the movement of the thread guide, for example to supply energy to a control or regulation device and/or a drive device and/or a Braking device, provided via cable and/or wirelessly and/or by energy harvesting and/or with the aid of a battery and/or via a medium. The aforementioned options for providing energy can either be used individually, or it can be provided that the energy for moving, influencing the movement, and / or controlling or regulating, with the help of a combination of some or all of the aforementioned options Energy provision is provided. While providing the energy via cable is particularly easy By providing the energy wirelessly, the otherwise necessary cabling can be avoided and space saved. If the energy is provided with the help of a battery, the movement or influencing the movement of the thread guide and/or the corresponding control or regulation of the movement can take place for a certain period of time independently of other external energy sources. On the other hand, the provision of energy through energy harvesting enables a certain independence from any cabling and batteries that have to be replaced after a certain operating time, by using energy present in the environment, for example from movements of the machine, light in the environment, temperature differences, etc. can come from, is “harvested”.

In one embodiment, the thread guide can be made of a ceramic material. This can have a positive effect on the wear resistance and service life of the thread guide.

Alternatively, in one embodiment, the thread guide can be formed, for example, with a metal material, for example stainless steel. In other words, the thread guide could be made of metal, for example in order to advantageously use the distribution of the effect of the thread friction over a large number of points on the thread guide to improve the service life.

In one embodiment, the thread guide can be designed as an input thread guide, for example between a cooling rail outlet or cooling pipe and a Unit input of a texturing unit, in particular a DTY/ATY texturing machine, may be arranged.

In a further development of the unit according to the invention, the unit is designed as a texturing unit. Particularly in the case of texturing units, thread guides, in particular the input thread guide or output thread guide, are heavily loaded. Particularly in the case of texturing units, the invention therefore offers the advantageous possibility of significantly increasing the service life of the thread guide.

In a further embodiment of the unit, the unit can have a control or regulation device by means of which the movement or movements of the thread guide can be controlled or regulated. In particular, the open-loop or closed-loop control device can communicate with a machine control or with another computer, whereby this communication can take place, for example, wirelessly or via cable. However, the control or regulation device can alternatively be omitted if control or regulation of the movement(s) of the thread guide is not to take place or the movement of the thread guide is due to the operating conditions under which the treatment or processing operation takes place, for example the operating parameters of the texturing unit , has already been determined.

In one embodiment of the method, the thread guide is moved with the running direction of the guided thread. With a corresponding development of the arrangement, the thread guide can be moved in the direction of travel of the thread.

In a further embodiment of the method, the thread guide is moved counter to the running direction of the guided thread. With a corresponding development of the arrangement, the thread guide can be moved counter to the direction of travel of the thread.

According to a further embodiment, the thread tension of the thread can be adjusted to achieve a predefined target thread tension by adjusting the movement speed, in particular the speed, and/or the direction of movement, in particular the direction of rotation, of the thread guide. For example, if the aim is to reduce the thread tension, the thread guide can be moved with the thread running direction, whereas if the aim is to increase the thread tension, the thread guide can be moved against the thread running direction.

According to a further embodiment of the invention, the tension of the guided thread can be detected using the thread guide. The thread guide can therefore be used as a thread tension sensor, for example in conjunction with a speed control. In this way, further, additional, useful information about the processing or processing process for the thread can be obtained.

In particular, if the thread guide is used as an input thread guide in a texturing process, the invention can be used not only to reduce wear, but also to achieve more targeted machine settings, at least according to some variants and a more targeted influence on the process. The more precise influence and, if necessary, control of the texturing process has an advantageous effect on the quality of the thread or yarn produced, just as the reduced wear on the thread guide is also advantageous for a good quality of the thread or yarn produced.

The refinements and developments described above with regard to the method can be applied in an analogous manner to the arrangement and the unit according to the invention, and vice versa.

The above configurations and further developments can be combined with one another in any way, if it makes sense. Further possible refinements, further developments and implementations of the invention also include combinations of features of the invention described previously or below with regard to the exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

Other embodiments and many of the advantages mentioned arise with regard to the drawings. The elements of the drawings are not necessarily shown to scale to one another.

DESCRIPTION OF EMBODIMENTS

The Figure 1 shows a texturing unit 1, which is equipped with a movable input thread guide 10 according to exemplary embodiments of the invention. The input thread guide 10 can be movable in a controlled or regulated manner. The input thread guide 10 can be movable with a fixed direction and speed of movement.

The texturing unit 1 has an arrangement 3 with the thread guide 10 designed as an input thread guide Variety of texturing disks 15, and a drive unit 21 for the texturing disks 15. The texturing disks 15 are stored in a suitable manner with the aid of bearing devices 18, which in the example shown are designed as shafts 18 rotating at high speed. The shafts 18, as elements of the texturing unit 1, each carry several of the texturing disks 15 and can, for example, each rotate about their respective longitudinal axis 18a at speeds between approximately 10,000 and 12,000 revolutions/minute.

Figure 1 also shows the thread 6, which passes through the texturing unit 1 in the running direction 8 and can be referred to as a texturing yarn. The input thread guide 10 arranged at the entrance of the texturing unit 1, for example a so-called DTY/ATY texturing machine, is designed in the form of a roll in the exemplary embodiment shown, with the thread 6 being guided into the texturing unit 1 via the input thread guide 10. However, in variants, the input thread guide 10 can also be designed other than roller-shaped.

The input thread guide 10 is made, for example, from a wear-resistant ceramic material. On the circumference of the input thread guide 10, a groove 19 is arranged all around, which is formed with a guide surface 19a for guiding the thread 6. The groove 19 is rounded at its base in all of the exemplary embodiments described here. The thread 6 is thereby not clamped by the input thread guide 10, but instead slides in a contact area due to a contact between the guide surface 19a and the thread 6 Speed difference present between thread 6 and input thread guide 10 over the guide surface 19a. The thread guide 10 makes it possible to ensure a thread tension suitable for texturing. However, other suitable cross-sectional geometries of the groove 19, which prevent the thread 6 from becoming trapped and enable it to slide over the thread guide 10, are also conceivable in variants.

In the unit 1, the thread 6 is texturized with the aid of the texturing disks 15, the thread 6 being “twisted” to create elasticity and crimping. Within a larger manufacturing arrangement or manufacturing machine, the input thread guide 10 can be arranged between a so-called cooling rail output or cooling pipe and the input of the texturing unit 1.

According to the exemplary embodiments of the present invention explained in more detail below, the input thread guide 10 is moved by means of the input thread guide 10 while the running thread 6 is guided in the running direction 8. The movement of the input thread guide 10 can, for example, take place in a preset manner, the input thread guide 10 can be moved in a controlled or regulated manner, or a movement of the input thread guide 10 can be influenced in a controlled or regulated manner.

In Figure 1 It is schematically sketched that while the thread 6 is being guided, the input thread guide 10 can rotate, for example, about the axis 11 of the thread guide 10, which represents an axis of rotation, which in Figure 1 through Arrows R1, R2 are indicated. In addition or as an alternative to the rotation R1 and/or R2, the thread guide 10 can carry out a translational displacement movement in the axial direction A', ie linearly along the rotation axis 11 of the thread guide 10. Such a translational movement is in Figure 1 schematically sketched back and forth for illustration purposes and provided with reference numbers T1 and T2. However, it is also possible to make the input thread guide 10 rotatable about further axes of rotation and/or translationally displaceable along further directions, which, however, is in Figure 1 is not shown graphically. Figure 8 However, shows by way of example further possible linear translations T3, T4 parallel to a radial direction R' of the input thread guide 10, as well as further possible rotations R3, R4 about an axis normal to the axis 11. The following statements relate to a rotation or a displacement movement of the thread guide 10 and their effect or influence can be applied in an analogous manner to further rotational and translational movements of the thread guide 10.

In Figure 1 The texturing unit 1, in which the thread 6 is processed by texturing, thus has an arrangement 3 for guiding the running thread 6, the input thread guide 10 forming part of the arrangement 3. The input thread guide 10 is mounted in such a way that the input thread guide 10 can be moved, for example, in the manner described above while guiding the thread 6. Figure 1A shows a schematic sketch of a possibility of a rotatable and displaceable mounting of the input thread guide 10 on a holding component 36, which is also only shown schematically. A bearing 12, which can also be referred to as a receptacle, enables translational displacement in the axial direction A 'parallel to the axis 11 of the thread guide 10 or against the axial direction A', as indicated by the arrows T2 and T1, respectively. In addition, the receptacle or bearing 12 allows the thread guide 10 to rotate about the axis 11 in opposite directions, as indicated by R1 and R2.

Figure 1B shows that the rotational movement of the input thread guide 10 can take place, for example, with the thread running direction 8, for example in the direction of arrow R2. Alternatively, the rotational movement of the input thread guide 10 can take place counter to the thread running direction 8, as in Figure 1B indicated by R1.

The input thread guide 10 can, for example, in some exemplary embodiments, be freely rotatably mounted on the holding component 36 or on a further element coupled to the holding component 36, with the input thread guide, which in this case is driven by the running thread 6, being used to control or regulate the movement of the input thread guide 10 10, which is set into a rotational movement R2 by the running thread 6, for example, is braked to influence and control or regulate the movement, in particular the rotational movement, of the input thread guide 10.

In other advantageous exemplary embodiments, the input thread guide 10 is driven by means of a drive device 28 provided for this purpose.

Figure 2 shows an arrangement 3 according to an exemplary embodiment, with an angularly designed holding component 36, in the exemplary embodiment Figure 2 the input thread guide 10 firmly on one in Figure 2 not visible shaft of the drive device 28 designed as a motor, for example as an electric motor. By means of the drive device 28, which is coupled to the thread guide 10 in this way, the thread guide 10 can be set in a rotational movement R1 or R2 about the axis 11 of the thread guide 10, which here represents an axis of rotation of the shaft of the motor and the thread guide 10. In the exemplary embodiment of Fig. 2 The input thread guide 10 is thus specifically driven for rotation about exactly one axis of rotation 11 by means of the drive device 28. The axis of rotation 11 runs here, as in Fig. 1 , transverse to the direction of thread travel 8.

As mentioned, the drive device 28 can be designed as an electric motor, by means of which the input thread guide 10 can be specifically set into rotation about the axis 11, as already mentioned Figure 1B mentioned, in the direction R1 opposite to the thread running direction 8, or in the direction R2 with the thread running direction 8. The rotation of the thread guide 10 can always only take place in one direction, or a combination of the rotational movements R1 and R2 can be provided, for example at different times or alternately .

The entrance thread guide 10 of the Fig. 2 can be driven in a first variant with a direction of rotation and speed preset by an operator, for example a drive of the input thread guide 10 can be provided with a substantially constant speed. Thus, the input thread guide 10 can be set in a substantially constant rotational movement R1 or R2 while guiding the thread 6. The speed of the input thread guide 10 can be, for example, between 5 and 20 revolutions/min, in particular between 8 and 10 revolutions/min.

In a second variant, the drive device 28 can be coupled to a frequency converter 55 or another control or regulation device. For example, a control or regulation device 66 can be provided for controlling or regulating the movement of the thread guide 10 and coupled to the frequency converter 55, see Fig. 2 , or the frequency converter can be part of the control or regulation device 66. In this variant, the input thread guide 10 can be set into a particularly uniaxial rotary movement R1 and/or R2 while guiding the thread 6, and the speed of the rotary movement and the direction of rotation can be controlled or regulated, for which the electric motor, which drives the drive device 28 forms, preferably speed-controlled.

The arrangement 3 according to the exemplary embodiment of Figure 2 This means that the running thread 6 does not just run over a single point on the thread guide 10 when the thread 6 is guided into the texturing unit 1. Instead, with just a uniaxial rotation of the input thread guide 10, it is possible to distribute the effect of the thread friction to a large number of points on the surface of the input thread guide 10, thereby avoiding strong local wear and excessive local heating of the input thread guide 10.

In the Figure 2 Drive device 28 shown can be designed in a further variant with an electric motor to effect a linear offset or displacement movement along the axis 11 of the thread guide 10 instead of a rotary movement. For example, a suitable gear, for example a spindle drive or the like, could be provided. In this way, in particular under the action of the control or regulation device 66, a targeted axial translational movement of the thread guide 10, as indicated by the arrows T1 and T2 as an alternative or in addition to the rotary movements R1, R2, is possible. For example, it can be an oscillating translational movement. In this variant too, the displacement speed and/or displacement direction can be controlled or regulated.

The movements R1 and/or R2, or in the variant explained above possibly also T1 and/or T2, are effected while the running thread 6 is being guided, that is to say during the operation of the entire system into which the texturing unit 1 is integrated. The manufacturing or processing process for the thread or yarn continues without the system having to be stopped. An arrangement 103 according to a further exemplary embodiment of the invention is shown in FIGS Figures 3 and 4 shown. While Figure 3 shows the arrangement 103 in its entirety Figure 4 Details of the internal structure of part of the arrangement 103. The arrangement 103 can be used instead of the arrangement 3 in the texturing unit 1 Figure 1 are used.

The arrangement 103 also has an angle-like holding component 36. The storage of the input thread guide 10 and the influence on the movement thereof should be made with reference to Figure 4 be described in more detail.

The entrance thread guide 10 in the Figures 3 and 4 is freely rotatable about the axis 11 of the thread guide, as indicated by the arrows R1 and R2. In detail, in this exemplary embodiment, the input thread guide 10 is rotatably mounted with the aid of a roller bearing 112 on a stationary axis 113 which is fixed relative to the holding component 36 and is firmly coupled to the holding component 36. The reference number 114 denotes the bearing seat for the thread guide 10. It also shows Figure 4 that, according to this exemplary embodiment, a braking device 45 is provided, by means of which the movement of the input thread guide 10 can be braked. At the in Figures 3, 4 In the exemplary embodiment outlined, the speed is influenced, thus the control or regulation of the speed of the input thread guide 10, in such a way that the input thread guide 10 is driven by the running thread 6 with the help of the friction of the thread 6 on the thread guide 10 and the movement of the input thread guide 10, with others Words, the speed of the input thread guide 10, is influenced with the help of the braking device 45. The targeted control or regulation of the speed of the thread guide 10 takes place while the running thread 6 is being guided by braking the thread guide 10.

In the Figure 4 The brake device 45 shown schematically can be designed in such a way that the movement of the input thread guide 10 is controlled mechanically - for example by friction -, electrically, magnetically, with the aid of a medium such as a gas or a liquid, or with a combination of some or all of the The aforementioned options can be braked in order to control or regulate the movement.

The braking device 45 is therefore coupled to the input thread guide 10 in such a way that a movement of the input thread guide 10 can be braked by means of the braking device 45 and can thereby be specifically influenced for its control or regulation. Although in Figure 4 is shown to influence a rotational movement of the thread guide 10 in this way, in variants a displacement movement of the thread guide 10, for example in a straight line along the axis 11, can be specifically influenced while guiding the thread 6 by means of a suitably designed device. Furthermore, the braking of both rotational and translational movements of the thread guide 10 is also conceivable.

Various possibilities, in particular a rotating movement R1 of the thread guide 10, such as that Fig. 4 to slow down and thereby influence it in a targeted manner in the Figures 4A to 4D schematically sketched. The thread guide 10 is only in Fig. 4A shown schematically for a better overview Figs. 4B-4D however omitted.

Shows as an example Fig. 4A a braking device 45 designed as a friction brake, which has brake shoes 46a and a brake disc 46b. Here, the brake disk 46b is preferably coupled to the thread guide 10 in a rotationally fixed manner. The brake shoes 46a are provided in such a way that their action on the brake disc 46b, e.g. B. using suitable brake pads, the desired braking effect is achieved.

In the variant of Fig. 4B a braking device 45 with an electromagnet 47a and/or a permanent magnet 47b is provided. The electromagnet 47a can be provided stationary, for example as part of a stationary element 47d, while a further, rotating element 47c is provided, which is coupled in a rotationally fixed manner to the thread guide 10 or forms part of the thread guide 10. The braking effect can be achieved by supplying the electromagnet 47a with electrical current and thus interacting with the permanent magnet 47b or, with a suitable choice of material, with the element 47c, such that the rotational movement of the thread guide 10 is braked.

Figure 4C shows schematically a braking device 45, which is constructed in the manner of a viscous coupling with two disks or disk groups 48a, 48b, with then between the disks or disk groups 48a, 48b there is a fluid (also not shown) in a suitable housing (not shown in the drawing). The braking device 45 could also be designed in the manner of a hydrodynamic brake.

Another variant of a braking device 45 shows Fig. 4D . The braking device 45 of the Fig. 4D is designed with an eddy current brake and has an electromagnet 49a, which is arranged in a fixed manner, while a metal disk 49b made of a suitable metal material is coupled to the thread guide 10 in a rotationally fixed manner. The braking effect is brought about by supplying the electromagnet 49a with an electrical current.

In Figure 5 a machine 100 is shown according to a further exemplary embodiment of the invention, wherein a texturing unit, for example the texturing unit 1 of Figure 1 , is integrated into the machine 100 or interacts with it. In Figure 5 the texturing unit 1 is schematically sketched together with a movable input thread guide 10.

It can e.g. B. the arrangement 3 according to Figure 2 or the order 103 according to the Figures 3 and 4 in the machine 100 of Figure 5 be provided. The drive device 28 and, as an alternative, the braking device 45 are in Figure 5 shown schematically. Arrangement 3 or 103 is in Figure 5 positioned between a cooling rail output 99 and an input of the texturing assembly 1.

Furthermore, the control or regulation device 66 is in Figure 5 drawn. The control or regulation device 66 can be a component of the texturing unit 1. To control or regulate the movement of the thread guide 10, the open-loop or closed-loop control device 66 communicates on the one hand with the drive device 28 or the braking device 45, and on the other hand with a machine control 78 of the machine 100 or, alternatively or in addition, with an external computer 91. The communication of the open-loop or closed-loop control device 66 with the machine control 78 and/or the external computer 91 and/or the drive device 28 or the braking device 45 can take place, for example, via a cable or instead wirelessly, for example via radio.

To illustrate a variant shows Figure 5A a texturing unit 1 and an arrangement 303 with a thread guide 10 designed as an output thread guide in order to guide a running thread 6 out of the texturing unit 1. The comments regarding the example of Figure 5 , especially regarding the thread guide 10, can be applied in an analogous manner to the variant of Figure 5A find. In particular, the starting thread guide can Figure 5A moved in the same way or a movement thereof can be influenced in the same way as described above or below with regard to the input thread guide. The variants described above or below for storing, driving or braking an input thread guide 10 can also be applied analogously to an output thread guide, such as in Fig. 5A , be applied.

The energy that is required for bringing about or influencing as well as controlling or regulating the movement of the thread guide 10, in particular for the operation of the control or regulation device 66 and / or the drive device 28 or the braking device 45, is in the schematically outlined exemplary embodiment Figure 6A provided via a cable 29. Shows as an example Figure 6A only the drive unit 28.

According to the exemplary embodiment of Figure 6B The required energy is alternatively provided wirelessly by a remote energy source 30, for example in the form of electromagnetic radiation. This is indicated schematically in FIG. 6B.

According to the schematically outlined exemplary embodiment of Figure 6C The required energy is obtained through so-called energy harvesting, by “harvesting” energy from the environment, for example by generating energy from vibrations and/or movements of the texturing unit 1 and/or the machine 100, or by obtaining energy with the help of photovoltaic systems. Devices 31 are provided by photovoltaic means from ambient light 32, which comes, for example, from a lighting device 33, or from temperature differences in the environment with the help of, for example, Peltier elements 34.

In the schematically outlined exemplary embodiment Figure 6D the energy is provided with the aid of a battery 35, whereby the battery 35 can be, for example, an accumulator, but alternatively instead it is a non-rechargeable battery 35.

In the exemplary embodiment of Figure 6E On the other hand, the required energy is provided with the help of a medium, such as a gas or a liquid. The shows this Figure 6E a supply line 40, a return line 41, and flow directions 42 and 43 of the medium. If necessary, the return line can be dispensed with in variants if the medium can be released into the environment, for example if compressed air is used as the medium for this. Compressed air could, for example, be taken from a generally available compressed air supply of the machine 100 in order to drive a turbine (not shown) of the drive device 28.

In variants the in the Figures 6A to 6E The outlined ways of providing energy for the drive device 28 can be combined with one another in any way. In addition, in this way, ie with the solution one of the Figures 6A to 6E or a combination of some or all of these, not just the drive device 28 and in particular a motor thereof, such as that of Fig. 2 , but instead the braking device 45, such as that of 3 and 4 , be supplied with the required energy. Additionally or alternatively, one, some or all of the solutions may be used Figures 6A-6E be used to supply the control or regulation device 66 with energy. In case of Figure 6E The medium, such as compressed air, can be used, for example, to provide a braking force for braking the thread guide 10 with the aid of a suitable piston. In addition, for example, a viscous coupling or hydrodynamic coupling could be used to provide a braking effect Brake device designed as a brake is supplied with the medium, for example an oil, via the supply and discharge lines 40, 41.

The Figures 7A to 7E show how the thread guide 10, for example an input or output thread guide for the texturing unit 1, can be movably mounted according to various exemplary embodiments.

According to the exemplary embodiment of Figure 7A a needle bearing 201 is provided, by means of which the thread guide 10 is rotatably mounted on a stationary axis 113 about the axis of rotation 11.

According to the exemplary embodiment of Figure 7B the thread guide 10 is supported via a magnetic field 210, with devices 202 and 203 being able to be provided in the thread guide 10 and/or the stationary axis 113 to generate the repulsive magnetic forces.

In the exemplary embodiment of Figure 7C the thread guide 10 is air-bearing. For this purpose, the standing axis 113 is provided with an inner supply line 222 and with small openings 221, compressed air 220 being supplied through the supply line 222 in the standing axis 113, which flows out of the openings 221 and effects the storage of the thread guide 10. Instead, an aerodynamic mounting of the input thread guide 10 without a separate supply of compressed air is also conceivable.

According to the exemplary embodiment of Figure 7D the thread guide 10 is slide-mounted, for which a slide bearing 230 is provided is, which is formed, for example, by a suitable material selected for the standing axis 113 and a suitable sliding bushing 231 on the thread guide 10. However, other types of plain bearings are also conceivable.

The storage of the Figures 7A-7D can, for example, for the arrangement 103 of Figures 3 and 4 can be used to achieve free rotation and/or free displaceability of the thread guide 10.

In the exemplary embodiment of Figure 7E is the thread guide 10 on the rotating shaft 28a one in Figure 7E electric motor, not shown in its entirety, which forms the drive device 28. The shaft 28a in turn has a bearing 240, which in the exemplary embodiment shown is a ball bearing, e.g. B. rotatably mounted with low friction relative to a housing of the electric motor attached to the holding component 36. In this way, in the exemplary embodiment Figure 7E the thread guide 10 is mounted via the shaft 28a and the bearing 240 relative to the holding component 36, here rotatable. The storage of the Figure 7E can, for example, with arrangement 3 according to Figure 2 be used.

An arrangement 403 for guiding a running thread 6 into a texturing unit 1 according to a further exemplary embodiment shows Fig. 9 . With a view to the structure of the texturing unit 1, the comments will be made Fig. 1 referred. Also in Fig. 9 is the thread guide 10 as one Input thread guide 10 is formed and serves to guide the thread 6 into the texturing unit 1.

The entrance thread guide 10 of the Fig. 9 can be rotated about its axis 11 and thus about exactly one axis of rotation 11 while guiding the thread 6. The arrangement 403 in Fig. 9 can be designed for a rotation of the input thread guide 10 in the direction R1 against the running direction 8 of the thread 6 or in the direction R2 with the running direction 8 of the thread 6. For this purpose, the input thread guide 10 is specifically driven. See also Fig. 1B .

Also the ceramic input thread guide 10, for example Fig. 9 is roller-shaped and has a circumferential groove 19 with, for example, a rounded base on its circumference, in which the thread 6 is guided. The guide surface of the thread guide 10 is in Fig. 9 again designated 19a. The longitudinal axis 11 of the thread guide 10, which forms the axis of rotation, is transverse to the thread running direction 8 and transverse, in the example shown essentially perpendicular, to the axes 18a of the shafts 18.

In the exemplary embodiment of Fig. 9 a mechanical power for driving the input thread guide 10 and thus for causing the same to rotate about the axis 11 is tapped from one of the rapidly rotating shafts 18 of the texturing unit 1. By means of an angular gear 425 coupled to the input thread guide 10, of which in Fig. 9 only a housing is visible, the speed of the shaft 18 applied to the transmission 425 on the drive side and a torque picked up by the shaft 18 are converted into a transmission output speed and a Transmission output torque is converted, which then rests on the input thread guide 10 on the output side. A relatively small part of the mechanical power is therefore diverted from the shaft 18 and used to drive the thread guide 10. The high speed of the shaft 18 is reduced to a defined speed of the input thread guide 10 about its axis 11 by means of at least one reduction of the gear 425. While the shaft 18 can rotate, for example, at 10,000 to 12,000 revolutions/minute, for the input thread guide 10, for example, a speed in a range of 5 revolutions/minute to 20 revolutions/minute, in particular in a range of 8 revolutions/minute to 10 revolutions /minute. If the speed of the shaft 18, from which the power is drawn, is constant, the input thread guide 10 is then also rotated at a constant speed.

With the speed selection mentioned above, the input thread guide 10 is driven specifically for rotation at a defined angular speed, but the rotation of the input thread guide 10 takes place very slowly in comparison to the thread running speeds. The thread 6 thus slides over the guide surface 19a even in the case of the direction of rotation R2 and is thus guided. In a contact area of the thread 6 with the thread guide 10 Fig. 9 The peripheral speed of the thread guide 10 and the running speed of the thread 6 differ significantly.

It should be mentioned that other, possibly higher speeds for the input thread guide 10 can also come into question.

The gearbox 425 can be in Fig. 9 be designed with a bevel gear.

A constant reduction of the gear 425 can, for example, be determined in advance in such a way that, under the given operating conditions during the texturing process, in particular at the current speed of the shaft 18, from which the power for driving the thread guide 10 is tapped, for example, the desired one Speed of the input thread guide 10 is obtained. In order to achieve the desired reduction ratio, the gearbox 425 may optionally comprise (an) additional gear stage(s).

The transmission 425 on its drive side can be coupled to the shaft 18, for example, by plugging the transmission 425 onto an axial end face of the shaft 18 and transferring the rotation of the shaft 18 via a positive connection to a drive shaft of the transmission 425 ( in Fig. 9 not shown). However, the rotational movement of the shaft 18 can instead also be transmitted to the drive shaft of the gear 425 via a frictional contact, for example by means of a rubber element, such as a polyurethane disk. The mechanical power could be transmitted via a frictional contact on the end face of the shaft 18 or alternatively via a frictional contact with a peripheral surface of the shaft 18.

The aforementioned variants of coupling a drive shaft 430 of the gear 425 to the shaft 18 by means of a positive connection 435, as well as by means of a polyurethane disk 440 from the end face of the shaft 18 or by means of a polyurethane disk 445 from the circumference of the shaft 18 are in Figs. 11A-C schematically sketched.

A unit 1 with an arrangement 403, as described above with reference to Fig. 9 explained, shows schematically Fig. 10.

It should be mentioned that in variants of the exemplary embodiment (not shown in the drawing). Fig. 9 , 10, 11A-C the shaft from which the mechanical power is tapped and fed to the gear 425 can alternatively be an additionally provided shaft of the texturing unit, which does not carry any texturing disks 15. The speed of the additionally provided shaft could then correspond to that of the shaft 18 or differ from it.

In the above exemplary embodiments, it can also be provided that the speed and/or the direction of rotation of the thread guide 10 is or are adjusted in order to better achieve a predefined target thread tension of the thread 6. In the case of a drive device 28, for example, in addition to or without a variation in the speed, the direction of rotation can be reversed by appropriately switching and/or controlling the electric motor. In the example of the Fig. 9 The gearbox 425 could, for example, have a further gear stage via which the direction of rotation on the output can be reversed either permanently or optionally.

All of the exemplary embodiments described above can be used in connection with the input thread guide 10 or the output thread guide 10 of a texturing unit 1, see Figure 1 , 5 , 5A , 9 and 10, are applied.

With the help of a targeted, defined movement of the input thread guide 10, the wear behavior can be significantly improved. In addition, the control or regulation of the movement of the input or output thread guide 10 can enable more detailed process control through targeted, for example stepless control of the movement speed and a targeted adjustment of the direction of movement, in particular rotational speed or direction of rotation, of the input or output thread guide 10.

By improving the friction behavior of the thread 6 or yarn on the input thread guide 10, damage to the thread or yarn is avoided and its quality is improved in terms of many properties, for example with regard to tensile strength, elongation at break, shrinkage and/or dyeability. The stability of the manufacturing process can be improved in this way.

In addition, more detailed process control is possible by specifically causing or influencing the movement of the input thread guide 10, in some embodiments by controlling or regulating the movement of the input thread guide 10 by controlling or regulating the speed and direction of movement, the machine operator has further setting options. It can be done in this way, e.g. B. by more precisely influencing the number of twists per running meter of yarn, it can be better made, for example, so-called "slender yarn", "open yarn", or "highly twisted yarn". In addition, by specifically influencing or causing the movement of the input thread guide 10, the detailed shape of the twists, such as the length and height of the gathering arc, can also be influenced. In addition, the water absorption capacity, water-repellent properties, or optical effects of the thread or yarn can be defined and influenced more specifically through more detailed process control.

Overall, in some variants of the invention, the more detailed process control with the aid of the movable input thread guide 10 can enable a more targeted machine setting, a more precise control of the texturing process, and an improvement in the yarn quality. Similar advantages can be achieved with a movable starting thread guide 10.

The movable input thread guide 10, positioned between the cooling rail output 99 or cooling pipe and the unit input of a texturing unit 1, such as a DTY/ATY texturing machine, can have a rotation-changing effect on the yarn. By moving or influencing the movement of the input thread guide 10, further "curling effects" can be set in a targeted manner, without having to change other parameters such as temperature, speed, stretch (D/R) or the ratio between the rotational speed of the friction disks 15 and the delivery speed of the yarn (D/Y).

In addition, in further exemplary embodiments, the thread guide 10, in particular when the thread guide 10 is designed as an input thread guide, can be used as a thread tension sensor in connection with the control of the movement, in particular the speed control, of the thread guide 10, in other words, using the thread guide 10, the tension of the guided thread 6 can be detected.

It should be noted that, if necessary, in the exemplary embodiments described above, at least one measuring device 50, e.g. B. a speed sensor can be provided in order to be able to determine the current movement speed of the thread guide 10. An example is in Fig. 1B indicated. However, such a measuring device is not absolutely necessary and can be omitted in variants of the invention, which in particular aim to reduce wear on the thread guide.

Although the present invention has been fully described above using preferred exemplary embodiments, it is not limited to this but can be modified in a variety of ways.

In particular, the invention is not only applicable to input or output thread guides of texturing units, but can be used when guiding a thread or yarn in a wide variety of applications.
