Description

The present invention relates to a threading device for threading a melt-spun thread, in particular for threading a melt-spun thread in a winding device. The present invention also relates to a winding device for winding up a melt-spun thread, in particular a melt-spun thread composed of a plurality of filaments. Furthermore, the present invention relates to a method for laying on a melt-spun thread, in particular for laying out a melt-spun thread in a winding device.

In the production of synthetic threads, a molten polymer is fed into a spinneret under high pressure using a spinning pump and extruded into fine filament strands. The filament strands are combined into a thread after extrusion and after cooling. Several threads produced in this way are wound up parallel to bobbin packs in so-called winding machines.

Such a winding machine--also called a winding device--has a so-called winding spindle with a chuck for winding, on the circumference of which is arranged a clamping jacket with a clamping device for receiving and fixing winding tubes. A winding tube can be arranged on the winding spindle for each thread to be wound up. The winding spindle can be mounted on one side and cantilevered on a spindle carrier, so that the bobbin packages wound on the circumference of the winding spindle can be removed from the free end of the winding spindle after completion. The removal of the bobbin packages is also called doffing.

However, for the winding up of spun melt threads, they must first be suitably laid out in such a winding device. In other words, during melt spinning the extruded filament strands are combined into a thread and in the further process sequence several such threads are laid out for winding in a winding machine. In particular, the spun melt threads are placed on bobbin tubes for this purpose, which are arranged on a bobbin spindle of a take-up device.

Such an application of spun melt yarn to a winding tube arranged on a winding spindle requires a great deal of experience and technical skill on the part of the respective operating personnel. In particular, when a plurality of spun melt threads are laid, the threads may become undesirably caught or torn off. The respective application process must then be repeated, which is associated with an overall high expenditure of time and operation. In addition, this results in a high material waste.

Against the background set out above, the object of the present invention was to specify a feeding device for feeding a spun melt thread, with which the time and operating effort for feeding can be reduced and at the same time any material waste can be reduced. Furthermore, the task consisted in specifying a winding device for winding a spinning thread with such a feed device. Finally, the object of the invention consisted in specifying a method for laying on a spun-melt thread that can be carried out with reduced expenditure of time and operator effort and at the same time reduced waste of material.

With regard to the feed device, this object has been achieved by the subject matter of claim 1 and by the subject matter of claim 16, respectively. A take-up device is set out in claim 17 and a method of applying a fusible strand is set out in claim 18. Advantageous configurations are the subject matter of the dependent claims and are explained below.

A feeding device according to the invention for feeding a spun melt filament, in particular for feeding a spun melt filament in a winding device, is equipped with a suction unit for sucking in at least one spun melt filament, with a positioning device for guided movement of the suction unit and with a feeding aid device movably guided by means of the positioning device. The suction unit and the auxiliary positioning device can be arranged in different functional positions by guided movement by means of the positioning device, and the auxiliary positioning device is arranged to be movable relative to the suction unit in order to carry out an auxiliary positioning movement.

Due to the positioning device provided according to the invention, the suction unit and the feed-on aid device can be arranged in different functional positions required for the feed-on of the respective melt-spun thread in a take-up device with only little operating effort. At the same time, the auxiliary feed device, which is arranged to be movable relative to the suction unit in order to carry out an auxiliary feed movement, enables further increased flexibility for the guidance or positioning of a spun melt thread sucked in by means of the suction unit. As a result, a total manual operating effort is significant or limited reduce a small amount. The risk of snagging or tearing off of the spun melt thread to be applied can be reduced as a result. Advantageously, with an application device according to the invention, the application process can be carried out in a fully automated or at least partially automated manner. The process reliability of the application can be increased in this way.

According to an advantageous embodiment of the feed device, the feed aid device can be designed as a feed roller. Such a feed roller requires only little structural effort and at the same time enables the respective spun melt thread to be reliably grasped and guided into the desired position within a winding device.

In a further preferred manner, a spun melt thread sucked in by the suction unit can be contacted by the auxiliary attachment device for guiding and/or positioning. The feed-on aid device or a feed-on aid device designed as a feed roller can contact a spun melt thread in a state in which it has been sucked in by the suction unit and then carry out the desired positioning in each case. This enables a particularly advantageous interaction of the suction unit and the attachment aid, as a result of which automated handling during an attachment process can be further improved.

According to a further advantageous embodiment, the suction unit and/or the positioning aid can be arranged by guided movement by means of the positioning device in a thread take-over position in which at least one spun melt thread can be picked up and/or sucked in by a thread injector and/or a spinneret. In particular, in a thread take-over position, at least one spun melt thread can be initially received and/or sucked in by a thread injector and/or a spinneret. In a thread take-over position, a spun melt thread exiting from a spinneret and/or a thread injector can accordingly be initially sucked in by the suction unit and thus picked up.

In such a state of the spunbonded filament being sucked in and picked up by the suction unit, the suction unit can preferably be moved into at least one further functional position while the spunbonded thread being sucked in and thus picked up is maintained. Due to the possibility of arranging the suction unit in a thread take-over position, a process for the creation of a spun melt thread can be started in an advantageous manner, in particular without manual intervention by an operator.

According to an even further advantageous embodiment, the suction unit and/or the positioning aid can be arranged in a thread cutting position by guided movement by means of the positioning device, in which at least one spun melt thread can be severed and/or cut by a thread cutting device. A thread cutting device can advantageously be a thread cutting device of a winding device and/or a so-called shirring device. With such a shirring device, spun melt threads can be cut or severed with a high level of safety and accuracy and at the same time with little design effort. Accordingly, the thread cutting position can be a chopper feed position in which at least one spun melt thread can be severed and/or cut by a shirring chopper device.

Cutting and/or severing of a meltspun filament may be required to complete and/or interrupt a winding operation, for example in the event of undesirable miswinding or snagging of meltspun filament during application. After cutting or severing a spun melt thread, a piecing process can be initiated again. Due to the possibility of arranging the suction unit in a thread cutting position, the cutting or severing of a spun melt thread can be accomplished with little effort, in particular without manual intervention by an operator.

According to an even more preferred embodiment, the suction unit and/or the positioning aid can be arranged by guided movement by means of the positioning device in a drafting system positioning position in which at least one melt-spun thread can be positioned in a drafting system, in particular a drafting system with several godets. In such a drafting system, a melt spun thread can, for example, be pre-stretched or pre-oriented and thus subsequently wound up as a pre-stretched or pre-oriented yarn (POY yarn). Due to the possibility of arranging the suction unit in a drafting system laying-on position, the pre-stretching or pre-orientation of a melt spun yarn prior to winding can be accomplished with little effort, in particular without manual intervention by an operator.

In an even more preferred manner, the suction unit and/or the positioning aid be able to be arranged in a thread distribution position by guided movement by means of the positioning device, in which at least one spun melt thread can be positioned by a thread distribution device along a thread distribution direction and/or contacted by a thread distribution device for positioning in a thread distribution direction. The thread distribution position can be, in a particularly advantageous manner, a collecting roller laying position in which at least one spun melt thread can be placed on a collecting roller and/or can be contacted by a movably arranged collecting roller.

In particular, in a collecting roll application position, a plurality of spun melt threads can each be placed on a collecting roll and/or each be able to be contacted by a movably arranged collecting roll. Accordingly, a thread distribution device, in particular a thread distribution device of a winding device, can advantageously be designed as a collecting roller device with a plurality of collecting rollers. In each case one collecting roller can be designed and/or arranged for contacting a spun melt thread.

In other words, a melt spun thread can be applied to such a collecting roller or contacted by such a collecting roller and then positioned by the respective collecting roller in a thread distribution direction or prealigned at the desired thread position along the longitudinal direction of a winding spindle. Due to the possibility of arranging the suction unit in a thread distribution position, the positioning of a melt spun thread in a thread distribution direction can be accomplished by a thread distribution device in advance of winding with little effort, in particular without manual intervention by an operator or with at least reduced operating effort.

In an even more preferred manner, the suction unit and/or the positioning aid can be arranged by guided movement by means of the positioning device in a longitudinal alignment position in which at least one spun melt thread can be aligned in the longitudinal direction of a winding spindle, in particular by a longitudinal alignment device, and/or can be placed on a longitudinal alignment device and/or or threadable into a longitudinal alignment device. A longitudinal alignment device can preferably be designed in the form of a so-called lower exchange unit. The longitudinal alignment position can, in particular, be what is known as a lower changing unit, laying position (UWE laying position).

A longitudinal alignment device or a lower changing unit of a winding device can be arranged below a winding spindle in the winding position or approximately at the same height as a winding spindle in the winding position and can guide several melt spun threads in defined positions spaced apart from one another along the longitudinal direction of a winding spindle or into the positions spaced apart from one another move.

The spun filaments that are caught, moved and/or guided in position by a longitudinal alignment device or by a lower changing unit can each be fed to a winding tube arranged on the winding spindle and thus wound up on the respective winding spindle. In order to guide or move the spun melt threads, they can be threaded into the longitudinal alignment device or into the lower changing unit, namely in defined receptacles and/or by means of catch hooks. For threading molten strands into a longitudinal alignment device or into a lower changing unit, this can be moved or moved into an open position or into a threading position and/or collection position. After threading or catching the spun melt threads, the longitudinal alignment device or the lower changing unit can be moved or moved into a closed position or guide position and/or distribution position.

Due to the possibility of arranging the suction unit in a longitudinal alignment position, the alignment of the spun melt threads in the longitudinal direction of a winding spindle and/or the application to and/or threading in a longitudinal alignment device or in a lower changing unit prior to winding can be accomplished with little effort, in particular without manual intervention by an operator or with at least reduced operating effort.

More preferably, the suction unit and/or the placement aid can be arranged by guided movement by means of the positioning device in a winding spindle position in which at least one spun melt thread can be placed on a winding spindle, in particular on a winding tube arranged on a winding spindle.

In a particularly preferred manner, the suction unit and/or the positioning aid can be arranged by guided movement by means of the positioning device in a winding spindle position in which at least one spun yarn is set in motion by a spindle turret carried on a spindle turret and/or by a spindle turret Spool spindle can be contacted and/or captured. In particular, a melt-spun thread can be contactable and/or catchable in a winding spindle position by a winding tube which is arranged on a winding spindle carried by a spindle turret and/or set in motion by a spindle turret.

Thus, in a winding spindle position, the respective spun melt thread can be placed in contact with a winding tube or caught by a movement of the respective winding spindle and a winding tube arranged thereon, generated by means of a spindle turret, and the actual winding process can be started.

Due to the possibility of arranging the suction unit in a winding spindle position, the spun melt threads can be placed on a winding spindle or on a winding tube that is arranged on the winding spindle with little effort, in particular without manual intervention by an operator or with at least less operating effort.

According to a further preferred embodiment, the winding spindle position of the suction unit can coincide with the longitudinal alignment position of the suction unit.

In a particularly preferred manner, the positioning aid device can be arranged and/or set up to carry out an positioning aid movement relative to the suction unit, starting from a functional position assumed by means of the positioning device. In particular, starting from a thread takeover position, a thread cutting position, a drafting system feed position, a thread distribution position, a longitudinal alignment position and/or a winding spindle position, an auxiliary feed movement of the feed aid device relative to the suction unit can be undertaken.

An auxiliary positioning movement of the auxiliary positioning device relative to the suction unit can therefore contribute to carrying out individual functional steps during a thread positioning process.

In particular, an auxiliary feed movement can contribute to the thread takeover of a melt spun thread from a thread injector and/or a spinneret through the suction unit, for example by catching the respective thread and/or feeding the thread to the suction unit.

Furthermore, an auxiliary positioning movement can contribute to the severing and/or cutting of a melt-spun thread by a thread cutting device, for example by feeding the thread to the respective thread cutting device.

Furthermore, an auxiliary positioning movement can contribute to the positioning of a melt-spun thread in a drafting system, in particular by feeding the thread to the respective godets of a drafting system.

Furthermore, an auxiliary positioning movement can contribute to the positioning of a spun melt thread in a thread distribution device, in particular by feeding the respective thread to collecting rollers.

Furthermore, an auxiliary positioning movement can contribute to the positioning of a spun melt thread in a longitudinal alignment device, in particular by feeding the respective thread to catch devices or catch hooks of a longitudinal alignment device.

Furthermore, an auxiliary positioning movement can contribute to the positioning of a spun melt thread on a winding spindle or a winding tube arranged on the winding spindle, in particular by feeding the respective thread to a winding tube arranged on the winding spindle.

The directions “vertical” and “horizontal” used below relate to an installed and/or operating state of a feeder device, in particular to a state installed in a winding device and/or mounted on a reeling device or operating state of the feeder device. In particular, the directional statement “vertical” relates to a y-direction and the directional statement “horizontal” to an x-direction or a z-direction, as shown for example in the figures and described in more detail below.

According to an even more preferred embodiment, at least some of the functional positions of the suction unit and/or the positioning aid that can be assumed by the positioning device can be distributed in the vertical direction. Consequently, the suction unit and/or the positioning aid can be arranged one after the other in vertically distributed functional positions by means of the positioning device along the guide rail. Manual vertical movements of the suction unit can be replaced or imitated in a particularly advantageous manner by a distribution in the vertical direction. A vertical movement sequence is also suitable for winding a melt-spun filament starting from a spinneret or a filament jector to a winding spindle arranged vertically below it, on which a winding process can be carried out.

More preferably, functional positions can be assumed in a predetermined order by means of the positioning device. Particularly preferably, functional positions can be assumed by means of the positioning device in the predetermined sequence of thread take-over position, thread cutting position, drafting system laying-on position, thread distribution position, longitudinal alignment position and winding spindle position.

With a predetermined sequence and/or such a vertically distributed arrangement of the respective functional positions, the suction unit and/or the attachment auxiliary device can be moved by means of the positioning device in order to carry out a predetermined process sequence for the attachment. The respective individual steps can therefore be carried out in the order of vertically successive functional positions.

According to a further preferred embodiment, at least two functional positions of the suction unit and/or the positioning aid that can be assumed by means of the positioning device can be offset from one another in the horizontal direction. In particular, a thread cutting position that can be assumed by means of the positioning device and/or a drafting system application position that can be assumed by means of the positioning device can be offset in the horizontal direction with respect to at least one further functional position. For example, by arranging a functional position offset horizontally in relation to a further functional position, the suction unit and thus also a respectively suctioned spun melt thread can be moved in sections in the horizontal direction during the laying-on process. The geometric conditions or the respective component arrangement of a winding device can thus be taken into account in an advantageous manner.

According to an even further preferred embodiment, an auxiliary positioning movement of the auxiliary positioning device can take place in the horizontal direction. In particular, a horizontal movement of the feed-on aid device relative to the suction unit allows a spun melt thread sucked in by the suction unit to be moved at least in sections in the horizontal direction during the feed-on process, which advantageously allows the geometric conditions or the respective component arrangement of a winding device to be taken into account.

According to a further advantageous embodiment, the positioning device can be designed as a lifting device and/or as a portal device. Such a positioning device requires only a small amount of installation space and enables movable guidance with a relatively high level of accuracy. In particular with a portal device, a movement can take place in several dimensions.

Furthermore, the positioning device can have at least one driven linear axis and/or be designed for guided movement of the suction unit and/or positioning aid device along a positioning plane. Such a linear axis ensures mobility over long distances and the guided movement along a positioning plane ensures movement in space with a high degree of flexibility.

In a further preferred manner, the positioning device can have at least two driven linear axes, in particular two linear axes running at an angle or transversely to one another. Furthermore, a linear axis of the positioning device can be carried by a further linear axis of the positioning device and/or can be moved by a further linear axis. Additionally or alternatively, a driven linear axis of the positioning device can be held and/or guided on a positioning carriage of a further linear axis. Such an embodiment can be implemented with relatively little structural effort and ensures a high degree of movement options for the suction unit or for the positioning aid.

According to a further preferred embodiment, a linear axis of the positioning device can be designed as a lifting axis and/or a linear axis of the positioning device can be designed as a transverse axis. In this case, the transverse axis can preferably be arranged on the lifting axis and/or carried by the lifting axis, in particular by a positioning slide of the lifting axis. As a result, lifting movements can be accomplished along relatively long distances, particularly in the vertical direction. If necessary, movements over smaller distances can be accomplished via the transverse axis, for example along a horizontal direction.

More preferably, the positioning device can have at least one drive device, in particular a plurality of drive devices. Each driven linear axis can have its own drive device. At least one drive device can be designed as a toothed belt drive and/or at least one drive device can be designed as a spindle drive. Thereby can a driven lifting axis preferably has a toothed belt drive and/or a driven transverse axis preferably has a spindle drive. A toothed belt drive is structurally simple and at the same time ensures linear movements over long distances. A spindle drive can ensure positioning with particularly high accuracy.

It can also be advantageous if a drive unit of the lifting axis and/or the toothed belt drive is fixed to a lifting linear guide and/or engages with a toothed belt running along a lifting linear guide. In this case, the toothed belt of the lifting linear guide can preferably be fastened to a lifting positioning carriage that is movably guided along the lifting linear guide. The drive unit can thus be arranged in a stationary and/or immovable manner, as a result of which the moving mass can be kept low. This enables high accelerations with low energy requirements at the same time.

More preferably, a drive unit of the transverse axis and/or the spindle drive can be fixed to a transverse linear guide and/or can engage with a drive spindle running along a transverse linear guide. The transverse linear guide can preferably be held and/or guided on a lifting positioning carriage of the lifting linear guide. Such an arrangement can be implemented in a structurally simple manner and at the same time ensures a high degree of functional reliability. In addition, such a configuration enables high accelerations along the transverse axis with a simultaneously low energy requirement.

According to an even more preferred embodiment, the suction unit and/or the positioning aid can be movably arranged relative to a driven linear axis of the positioning device, in particular relative to a driven lifting axis, particularly preferably along a driven transverse axis of the positioning device. The suction unit and/or the positioning aid can be fastened and/or held on a transverse linear guide of a driven transverse axis. Particularly preferably, the suction unit and/or the positioning aid can be fixed or carried on a transverse linear slide or on a transverse linear support, it being possible for the transverse linear slide or transverse linear support to be driven to move along the transverse axis.

Consequently, the suction unit and/or positioning auxiliary device can be arranged so as to be movable relative to the lifting axis, in particular along the transverse axis, for changing the distance. A mobility of the suction unit and/or the positioning aid device relative to the lifting axis can be configured in particular transversely to a direction of movement of the suction unit and/or the positioning aid device along the lifting axis. The mobility of the suction unit and/or the auxiliary feed device can be configured relative to the lifting axis and/or along the transverse axis, in particular at an angle or transversely to a longitudinal direction of the winding spindle of a winding device.

Advantageously, due to the movable arrangement of the suction unit and/or the positioning aid device relative to the stroke axis, individual melt spinning threads can be assigned or fed to the contact positions of a thread distribution device. For example, such a thread distribution device can be formed by a plurality of collecting rollers, and the movable arrangement of the suction unit and/or the feeding aid device relative to the lifting axis and along the transverse axis can assign or feed individual spun melt threads in a depth offset direction of a winding device and thus to individual collecting rollers. At least some of the collecting rollers can be distributed transversely to their own direction of movement and thus offset in depth.

In an even more preferred manner, the auxiliary positioning device can have a drive device, in particular a pneumatic drive, for carrying out an auxiliary positioning movement relative to the suction unit. The positioning aid device can be movably arranged and/or driven at an angle to the linear axes and/or at an angle to a positioning plane of the positioning device for carrying out an auxiliary positioning movement.

Consequently, the positioning aid for changing the distance can be arranged to be movable relative to the suction unit and thus also relative to the lifting axis and relative to the transverse axis. In particular, the positioning aid can be arranged to be movable relative to the lifting axis and/or relative to the transverse axis in a horizontal direction and/or at an angle to the longitudinal extent of the lifting axis and/or the transverse axis. Particularly preferably, the positioning aid can be arranged so as to be movable transversely to a plane of movement defined by the course of the lifting axis and the transverse axis.

A mobility of the positioning aid device relative to the transverse axis can be configured, in particular, transversely to a direction of movement of the suction unit and/or positioning aid device along the transverse axis. The mobility of the positioning aid device relative to the transverse axis be formed in particular along or parallel to a longitudinal direction of the winding spindle of a winding device. Such an arrangement of the feed-on aid means that a spun-melt thread can be moved in a further spatial dimension, so that a further degree of freedom for the guidance of a spun-melt thread in a feed-on process can be ensured.

In a particularly advantageous manner, the movable arrangement of the positioning aid device relative to the transverse axis can assign or feed individual spun melt threads to the contact positions of a thread distribution device and/or to the catch hooks of a longitudinal alignment device.

According to a further preferred embodiment, the suction unit can be designed as a suction gun. Additionally or alternatively, the suction unit can have at least one connection for the supply and/or discharge of compressed air and/or the suction unit can have at least one suction opening for sucking in a spun melt thread. Such a design of the suction unit is associated with only little structural effort and at the same time ensures a high level of functional reliability for the suction of a spun melt thread.

Another independent aspect of the present invention relates to a threading device for threading a spun melt thread, in particular for threading a spun melt thread in a winding device, with a suction unit for sucking in at least one spun melt thread with a positioning device for guided movement of the suction unit, the suction unit being guided by movement by means of the positioning device can be arranged in different functional positions and wherein the positioning device for the guided movement of the suction unit has two driven linear axes running at an angle to one another.

The preferred configurations and advantages described above with regard to the feeding device for feeding a spun melt thread also apply in the same way to the further independent aspect of the feeding device described above.

With a positioning device designed in this way according to the further independent aspect of the present invention, the suction unit can be arranged with only little operating effort in a large number of functional positions required for the application of the respective spun melt thread in a winding device. In this way, in particular, a movement along several dimensions can be accomplished with little effort. Manual operating effort can thus be significantly reduced or reduced to a minimum. The risk of snagging or tearing off of the spun melt thread to be applied can be reduced as a result. Advantageously, with an application device according to the invention, the application process can be carried out in a fully automated or at least partially automated manner. The process reliability of the application can be increased in this way.

A further aspect of the present invention relates to a winding device for winding a spun melt thread, in particular a spun melt thread made of a plurality of filaments, with a winding spindle through which at least one spun melt thread can be wound on a bobbin tube to form a bobbin pack, and with a feed device described above, wherein the Suction unit and/or the feed-on auxiliary device of the feed-on device for feeding-in the spun thread can be arranged on a winding tube arranged on the winding spindle.

According to a preferred embodiment, the winding device can be characterized by at least one stationary feeding device, in particular by at least one stationary feeding roller, through which a spun melt thread sucked in by the suction unit can be contacted for guiding and/or positioning. Such a stationary positioning aid can preferably be arranged on a device frame and/or a device housing so that it can be moved to a limited extent. In a further preferred manner, the winding device can be equipped with a plurality of stationary auxiliary feed devices, in particular with a plurality of stationary feed rollers, particularly preferably with a total of three stationary auxiliary feed devices.

With such a positioning aid, a spun melt thread sucked in by the suction unit can be contacted in a suitable manner and brought into the desired position by moving the positioning aid, in particular for the purpose of contacting the respective device component.

According to a preferred embodiment, the winding device can be equipped with a spindle turret on which the at least one winding spindle is arranged or carried. Particularly preferably, two or more winding spindles can be arranged or carried on the spindle turret. More preferably, a winding spindle can be moved between different spindle positions by moving the spindle turret, in particular between a winding position for Winding of a spun melt thread and a doffing position for doffing or removing wound packages from the respective winding spindle. In a doffing position of the winding spindle, it can also be loaded with new winding tubes after the respective wound packages have been removed.

Another independent aspect of the present invention relates to a method for feeding a spun melt thread, in particular for feeding a spun melt thread in a winding device, in which a spun melt thread is sucked in by a suction unit, in which the suction unit is movably guided in the suction state together with a feeding auxiliary device by means of a positioning device , in which the suction unit is arranged in a plurality of successive functional positions by means of a guided movement by means of the positioning device, in which the auxiliary feed device is moved relative to the suction unit in order to carry out an auxiliary feed movement, and in which the at least one spun melt thread that has been sucked in is in a functional position of the suction unit on one on one Winding spindle arranged winding tube is applied.

Another independent aspect of the present invention relates to a method for piecing a spunbonded filament, in particular for piecing a spunbonded filament in a winding device, in which a spunbonded filament is sucked in by a suction unit, in which the sucking unit is in the suction state by means of a positioning device with two driven and at an angle linear axes running in relation to one another, in which the suction unit is arranged in a plurality of successive functional positions by guided movement by means of the positioning device, and in which the at least one sucked spun melt thread is placed on a winding tube arranged on a winding spindle in a functional position of the suction unit.

The preferred configurations and advantages described above with regard to the feed device for feeding a melt spun yarn apply in the same way to the above-described winding device for winding a spun yarn and to the described method for winding a spun yarn.

1 12 shows a perspective view of a feeder 10 for feeding a melt-spun filament according to an embodiment of the present invention. The feeding device 10 can be designed and/or set up in particular for feeding a spun melt thread from a plurality of filaments. 2 Figure 12 shows a side view of the feeding device 1 and 3 shows a perspective detailed view of the application device 10 1 .

Insofar as “vertical” and “horizontal” directions are given below, these refer to an installation and/or operating state of the feed device 10, in particular to a state installed in a winding device 100, as in FIGS 4 until 10 shown.

The in the 1 until 3 The coordinate axes drawn agree with the coordinate axes in the 4 until 10 match. Consequently, the drawn y-axis runs in a vertical direction in an installed and/or operating state of the feed device 10 . The x-axis shown and the z-axis shown run in horizontal directions when the feed device 10 is installed and/or in operation, or the x-axis and the z-axis span a horizontal direction when the feed device 10 is installed and/or in the operating state level up.

The feeding device 10 for feeding a spun melt thread has a positioning device 12 , a suction unit 14 for sucking in at least one spun melt thread not shown here, and an auxiliary feed device 16 . The positioning device 12 is designed and/or set up for the guided movement of the suction unit 14 and for the guided movement of the positioning aid 16 . The suction unit 14 and the positioning aid 16 can be arranged in different functional positions by guided movement by means of the positioning device 12 . In addition, the auxiliary positioning device 16 can be arranged to be movable relative to the suction unit 14 in order to carry out an auxiliary positioning movement.

The feed aid device 16 can be designed as a feed roller. A molten filament sucked in by the suction unit 14 can be contacted by the positioning aid 16 for guiding and/or positioning. The feed-on aid device 16 or a feed-on aid device 16 embodied as a feed roller can contact a spun melt thread in a state that has been sucked in by the suction unit 14 and can then carry out the desired positioning in each case.

The positioning device 12 can in particular be designed as a lifting device and/or as a portal device. For this purpose, the positioning device 12 can have at least one driven linear axis 18 or 20, in particular two driven linear axes 18 and 20. The linear axes 18 and 20 can be arranged at an angle or running transversely to one another.

The thread distribution direction 120 can in particular run in a z-direction.

The suction unit 14 can also be guided by a positioning device 12 in an in 10 shown longitudinal alignment position can be arranged, in which at least one spun melt thread 102 can be aligned in the longitudinal direction of a winding spindle 104, in particular by means of a longitudinal alignment device. Preferably, the at least one melt-spun thread 102 can be placed in a longitudinal alignment position on a lower changing unit 124 and/or can be threaded into a lower changing unit 124.

A longitudinal alignment device can be formed, for example, in the form of a lower changing unit 124 . The spun melt thread 102 can be aligned in the longitudinal direction of the winding spindle 104 by laying it on and/or threading it into the lower changing unit 124 . In this case, the longitudinal direction of the winding spindle 104 corresponds in particular to the thread distribution direction 120 and/or a z-direction.

For this purpose, the lower changing unit 124 can be equipped with a plurality of catch hooks 126, which can each be set up to catch a spun melt thread 102 and, in the caught state, can carry out a longitudinal alignment of the respective spun melt thread 102. For this purpose, the catch hooks 126 are arranged to be movable along the longitudinal direction of the winding spindle 104 or along a z-direction, with 9 a collected position of the catch hooks 126 and in 10 a distributed position of the catch hooks 126 is shown.

The longitudinally distributed course of the spun melt threads 102 is in 7 shown in solid lines.

The threading of the spun melt threads 102 into the longitudinal alignment device or into the lower changing unit 124 can be carried out in a particularly advantageous manner by means of the auxiliary feed device 16 . Feed-on auxiliary device 16 can be used to move spun melt threads 102, starting from the longitudinal alignment position, in a longitudinal direction of winding spindle 104 or along a z-direction, thus promoting threading or catching by catch hooks 126 before the actual longitudinal alignment is carried out using the longitudinal alignment device or in the lower changing unit 124.

Finally, the suction unit 14 can be arranged by guided movement by means of the positioning device 12 in a winding spindle position in which at least one spun melt thread 102 can be placed on a winding spindle 104 or on a winding tube 106 arranged on a winding spindle 104 and/or carried by the spindle turret 105 and /or can be contacted and/or caught by a winding spindle 104 set in motion by a spindle turret 105.

A winding spindle position mentioned above may be that in FIG 10 schematically illustrated position of the suction unit 14 and/or the positioning aid or a position further down in the y-direction.

To apply the threaded and longitudinally distributed spun melt threads 102 to a winding spindle 104 or to a winding tube 106 arranged on a winding spindle 104, the longitudinal alignment device or the lower changing unit 124 can carry out a depth offset movement in a depth offset direction. Such a depth offset direction can in particular run at an angle to the longitudinal direction of the winding spindle 104, in particular transversely to the longitudinal direction of the winding spindle 104, or along a vertical direction and/or along an x-direction.

In order to carry out a depth offset movement, the catch hooks 126 can be moved together with the respective guide of the catch hooks 126 in the depth offset direction and can entrain the respectively threaded spun melt threads 102 in the depth offset direction.

After the depth offset movement has taken place, the winding spindle 104 with the winding tubes 106 arranged on it - in the not yet wound up state - can be moved by means of the in 4 spindle turret 105 shown can be moved or pivoted from a doffing position into a winding position. By such a movement or pivoting from the doffing position into the winding position, the spun melt threads 102 moved in the depth offset direction can be contacted by the winding spindle 104 or by the winding tubes 106 arranged on the winding spindle 104 and applied to them.

After the molten filaments 102 have been placed on the winding spindle 104 or on the winding tubes 106 arranged on the winding spindle 104, the movement of the winding spindle 104 can be continued up to the winding position. In the winding position, the respective winding process can be carried out and completed, and then the winding spindle 104 can return to the position shown in FIG 4 until 10 Doff position shown can be moved.

In a winding position, the winding spindle 104 is in the vertical direction or in the y-direction approximately at the level of the longitudinal alignment device or at the level of the lower changing unit 124. Transverse to the plane of the 5 until 10 or seen in the x-direction, the winding spindle 104 is located behind the longitudinal alignment device or behind the lower changing unit 124.

The longitudinal alignment device or the lower changing unit 124 can be equipped with cutting devices that enable the respective spun melt thread 102 to be cut or severed. In particular, such cutting devices can be designed and/or set up to cut or sever the respective spunbond thread 102 as soon as it has contacted and applied to the respective winding spindle 104 and the winding spindle 104 has reached the winding position or before the winding position has been reached.

The winding process can therefore begin after the respective spun melt thread 102 has been cut or severed by the longitudinal alignment device or the lower changing unit 124, and the cut or severed remainder of the melt spun thread 102 can be sucked in by the suction unit 14, so that the winding process is prevented from being adversely affected by the cut or severed remains can be.

As mentioned above, in the 4 until 10 each wound bobbin packs 108 shown, the bobbin packs 108 are only produced by completely winding a melt spun thread 102 on a bobbin tube 106 after the application. After completion of a winding process, the wound coil packs 108 are in 4 until 10 Doff position shown removed from the winding spindle 104 and the winding spindle 104 can be equipped with new unwound winding tubes 106. A new winding process can then be carried out.
