Description

The invention relates to a method for adjusting the delivery rate of thread fluid based on data from a winding device, an associated device and a winding device with the method and the device.

Determining the coil diameter is known from the general state of the art.

EP 0 816 806 B1 A method and a device for determining the diameter of a cross-coil driven by a friction roller are disclosed. Two sensors, spaced at a fixed distance along the circumference of the cross-coil, detect surface features of the coil. The sensor signals are evaluated in a correlator that calculates transit times. The circumferential speed of the cross-coil is then calculated by dividing the distance between the sensors by the transit times. The circumferential speeds and the angular velocities of the cross-coil are then divided to determine the diameter or radius of the cross-coil.

It is also known from the general state of the art to provide a preparation oil during the winding of a spool spindle over a predetermined time window.

DE 10 2018 008 716 A1 The invention discloses a method and a device for winding a multifilament thread with at least one winding point, wherein the thread is wound alternately and continuously onto two winding spindles to form spools, and wherein, after winding a full diameter of one of the spools, the thread is cut to wind a new spool. In this process, the thread is moistened with at least one preparation fluid before being wound onto a spool. To ensure, in particular, that a loose thread end can be reliably laid down at the circumference of the full diameter of the spool, the invention provides for increasing the flow rate of the preparation fluid and/or supplying an additional thread fluid to the thread before winding within a time window immediately before the thread is cut. Accordingly, a winding control device is connected to a control unit of a fluid pump of an upstream preparation device and/or to a control unit of a fluid pump of a separate thread wetting device.

However, the problem is that the controlled supply of the preparation fluid over a predetermined time window does not allow for necessary changes in the supply and/or delivery volume of preparation fluid that occur outside the predetermined time window.

Furthermore, the flow rate of the preparation fluid or the thread fluid is controlled only according to predefined conditions, which can lead to waste and/or environmental pollution.

The object of the invention is therefore to provide a method for adjusting the delivery rate of thread fluid, which allows for a more flexible and environmentally friendly response.

Furthermore, the invention aims to provide a device for adjusting the delivery rate of thread fluid, which allows for more flexible responses to changes.

It is also an object of the invention to provide a winding device that allows for more flexible responses to changes in the flow rate of thread fluid.

The problem is solved according to the invention with a method having the features of claim 1.

According to one aspect of the invention, a method is provided for adjusting the delivery rate of thread fluid of a winding device for winding a synthetic filament bundle onto a winding spool, wherein, based on determined data of the winding device, in particular a spool diameter of the winding spool, a delivery rate of thread fluid is controlled and applied to a synthetic filament bundle.

The method for adjusting the flow rate of thread fluid allows the flow rate to be regulated based on acquired data. In a regulated system, the flow rate of thread fluid is controlled based on acquired data. In a controlled system, the flow rate is controlled according to a predefined program without taking additional changes into account.

The thread fluid can be used to prepare the synthetic filament bundle, making it easier to process, reducing static charge, and/or allowing for simplified bundling of the filaments forming the filament bundle.

The thread fluid can also be used to moisten and wet a winding sleeve so that the winding sleeve is sufficiently moistened, preventing further absorption of the thread fluid by the winding sleeve.

A winding device, as used here, refers to a winding device designed for winding synthetic filament bundles. This could be, for example, a winding device for pre-oriented yarn (POY) or fully drawn yarn (FDY). The process can also be applied to textured yarns or drawn textured yarn (DTY). In all cases, the addition of yarn fluid may be necessary to maintain the required quality standards.

According to a preferred embodiment of the method, the determined data include at least one of the following parameters: a rotational speed of a chuck, a rotational speed of a contact roller, a diameter of a winding coil, a fluid pump rotational speed of a fluid pump, an acceleration of the fluid pump rotational speed, an energy consumption of a drive of the chuck, an energy consumption of a drive of the contact roller, an energy consumption of a drive of a fluid pump and/or an optically determined measurement signal.

The data may be data that is particularly relevant to the quality of the synthetic filament bundle.

This data can be taken from the control unit of the winding device and provided to a separate control unit for the supply of the thread fluid.

The respective data are either prepared or determined by the control of the winding device and/or a control of the thread fluid conveying system.

The data obtained by the winding device can include, in particular, the rotational speed of a chuck, the rotational speed of a contact roller, the diameter of a winding coil, the rotational speed of a fluid pump, the energy consumption of a chuck drive or a contact roller drive and/or an optically determined measurement signal.

The rotational speeds of the contact roller or chuck can be determined by the winding device's control system, for example, via the energy consumption of the respective drive. The diameter of a winding coil can then be calculated from the rotational speed or energy consumption. As the winding device increases the diameter of the winding coil, the rotational speed decreases, allowing for more uniform winding of the coil.

Furthermore, the rotational speed of a fluid pump can also be used for control and/or regulation, as the speed determines the flow rate of filament fluid that can be delivered over a predetermined time period. Based on the collected data, the start and duration of the delivery process can be determined by calculating the delivery rate in relation to the pump's rotational speed.

Additionally or alternatively, the diameter of the winding spool can be detected using a camera, which transmits this information to the control system via optical signals. These optical signals can then be evaluated to determine the diameter of the winding spool.

The data listed here is not exhaustive. However, the diameter of the winding coil can be deduced from the respective data. A combination of the respective data can be used for redundancy and/or to verify the respective results.

To determine the required flow rate of filament fluid, the current rotational speed of a fluid pump can also be measured. If a higher flow rate is needed, the fluid pump's rotational speed can be accelerated and maintained for a predetermined period. This acceleration is preferably performed before the filament bundle is laid onto the winding spool, so that a higher flow rate is available when the filament bundle is laid onto the winding spool.

According to a further preferred embodiment of the method, the thread fluid is applied locally in the filament bundle thread direction upstream of the winding device and/or inside the winding device onto the synthetic filament bundle, wherein the thread fluid is provided for static discharge, for reducing friction, for grouping filaments into a filament bundle and/or for wetting a winding sleeve on which the filament bundle is wound.

The supply of thread fluid can be provided and applied at different positions on the winding device.

Locally, in front of the winding device shortly after a melt spinning process, the filament bundle can be treated with thread fluid in the form of preparation oil.

The preparation oil then serves to reduce the friction of the filament bundles, to avoid static charging and/or to simplify the bundling of the filaments from the melt spinning device into a filament bundle.

Additionally or alternatively, the thread fluid can also be provided within the winding device.

Preferably, the filament bundle can be fed between a galette carrier and a changing device. This allows, for example, for appropriate pre-wetting of a winding core onto which the synthetic filament bundle is wound. The winding core is generally a paper core. The paper core can lead to premature drying of the filament bundle if insufficient filament fluid is supplied.

If a larger quantity of thread fluid is supplied to the filament bundle to be wound, the winding sleeve can be pre-wetted with thread fluid accordingly, so that the filament bundle to be wound is not dried out by the winding sleeve and subsequent re-processing of the filament bundle when pulling it off the winding sleeve is simplified and improved.

Pre-wetting is achieved by a larger flow rate of filament fluid, whereby the flow rate is increased by accelerating and increasing the speed of the fluid pump, so that sufficient filament fluid can be transferred to the winding sleeve with the filament bundle within a time window.

According to a particularly preferred embodiment of the method, the diameter or the diameter increase of a winding spool is determined to determine the delivery rate of thread fluid, wherein the speed of the fluid pump is controlled from the determined diameter or the determined diameter increase, whereby the speed of the fluid pump is accelerated to a predetermined value over a predetermined time window.

The flow rate of thread fluid supplied to the winding spool or filament bundle can, for example, also be adjusted via the determined diameter of the winding spool or the diameter increase of the winding spool over the spool run.

The diameter or the increase in diameter of the winding coil can be determined, for example, via the drive of the respective chuck on which the winding coil is wound.

For this purpose, for example a program is used to determine the rotational speed or energy consumption per unit of diameter of the winding spool at the respective time and to determine the necessary acceleration of the rotational speed over a time window, so that sufficient thread fluid can be provided over the time window.

According to a preferred embodiment of the method, the diameter or the diameter increase is determined based on a rotational speed of the winding coil, the rotational speed of the contact roller and/or the energy consumption of a drive of the chuck, a drive of the contact roller and/or on optical measurement data, wherein the rotational speed of the fluid pump and the acceleration of the rotational speed are determined from the determined data, so that the delivery rate of thread fluid can be controlled and supplied within a predetermined time window.

The diameter or diameter increase of a winding coil can be determined, for example, via the rotational speed of the winding coil. The rotational speed of the winding coil can be determined via the drive of the chuck on which the winding coil is mounted.

Additionally, the diameter can be determined via the rotational speed of a contact roller that is in contact with the winding coil during the winding process.

The rotational speed of the contact roller changes due to the increase in diameter or circumference.

This allows for a corresponding determination of the winding coil's diameter. Furthermore, the energy consumption of the chuck drive or the drive of the contact rollers can be used to deduce the diameter increase or the diameter of the winding coil itself.

Additionally, or as a redundancy, a camera can also be used to film the winding reel.

The optical images can then be used to deduce the diameter of the winding coil using appropriate programs.

The respective evaluation can be carried out via the control of the winding device and/or a corresponding control of a fluid wetting device.

Furthermore, a time window is defined within which the pumped fluid must be supplied. The speed of the fluid pump is then accelerated based on this time window, ensuring that the predetermined flow rate can be supplied over a predetermined period.

The problem is solved according to the invention with a device having the features of claim 6.

According to a further aspect of the invention, a device is provided for adjusting the delivery rate of filament fluid based on determined data from a winding device for winding a synthetic filament bundle onto a winding spool, in particular a spool diameter of the winding spool, wherein the device for carrying out the method according to at least one of the preceding claims 1 to 5 is configured, comprising a wetting device for wetting a synthetic filament bundle and a wetting control for regulating the delivery rate of filament fluid based on acquired data from the winding device and a fluid pump which is controlled by means of the wetting control.

The flow rate of the filament fluid in a winding device for winding synthetic filament bundles is controlled by a wetting device. The wetting device sprays or injects the filament fluid onto the filament bundle. The filament bundle then carries the fluid along, and additional vortex devices can be used to further improve the mixing of the filaments with the filament bundle.

Furthermore, the filament fluid moistens the winding core. The winding core is usually made of paper or cardboard. To prevent the absorbent cardboard of the winding core from drying out, additional filament fluid can be added to the filament bundle at the beginning of the winding process.

To determine the correct timing and flow rate for supplying yarn fluid, data from the winding device can be used. To ensure a sufficient flow rate of yarn fluid is provided over a predetermined time window, the data is used to determine when an increase in the speed of a fluid pump is necessary, and the required acceleration of the fluid pump to the required speed is then determined based on this time window.

According to a preferred embodiment of the device, the wetting device regulates the speed of the fluid pump and/or the acceleration of the speed of the fluid pump, so that the delivery rate of filament fluid is adjustable, wherein the speed of the fluid pump depends on the pressure gauge of the winding spool, and the acceleration is increased over a predetermined period before and after the application of filament bundles.

The process of attaching the filament bundles can include attaching them to thread guides and/or attaching them to a winding spool.

The wetting unit is supplied with the thread fluid via a fluid pump. The pumping action, or rather the pumping capacity, of the fluid pump is regulated by a wetting control unit. This means that, based on data acquired from the winding device, the flow rate of the thread fluid can be supplied to the wetting unit via the wetting control unit and the fluid pump.

According to a further preferred embodiment of the device, the wetting control is coupled with the control of the winding device, so that data from the control can be queried by the wetting control, wherein the wetting control determines the acceleration of the speed of the fluid pump based on the determined speed of the fluid pump and the defined time window.

The data can be queried by the user control from the control of the winding device and evaluated and assessed accordingly by the wetting control in order to provide and determine the necessary data for the control of the thread fluid.

According to a particularly preferred embodiment of the device, the rotational speed of the fluid pump is accelerated to a predetermined value before being applied to the winding sleeve and is maintained at the predetermined value at least for the duration of the formation of a first layer of filament bundles on the winding sleeve.

The user control system can, for example, use the recorded data to determine the diameter of a winding spool and deduce from this what quantity of thread fluid must be supplied to the filament bundle.

The diameter of the winding coil can also be determined, for example, via the rotational speed of a chuck, the rotational speed of a contact roller, or the respective energy consumption of the drives of the chuck and/or the contact roller.

The acceleration of the rotational speed is determined based on a predetermined time window and the required flow rate.

Additionally, as a redundant verification measure, an optical measurement signal can be evaluated, for example, from a suitable camera that records the diameter increase of the winding coil. Using appropriate evaluation software, the diameter of the winding coil can then be determined from the recorded optical signals, such as images.

The problem is solved according to the invention with regard to the winding device by a winding device having the features according to claim 10.

According to another aspect of the invention, a winding device for winding synthetic threads is provided, wherein the winding device has at least one chuck on which a winding sleeve for winding a synthetic thread can be mounted, a changing device for changing the synthetic filament bundle onto the winding sleeve to form a winding spool, and a contact roller which is movably mounted. The winding device has at least one method according to at least one of the preceding embodiments and/or a device according to at least one of the preceding embodiments.

The winding device is preferably a winding device designed for winding pre-stretched, fully stretched, and/or textured threads. However, the concept can also be applied to other winding devices that have at least one chuck and a contact roller.

The key aspect here is that the method and device allow for precise adjustment and control of the yarn fluid consumption, because data from the winding device is used to accurately regulate the yarn fluid flow rate, thus preventing unnecessary consumption. By evaluating the winding device data, the speed increase of the fluid pump and the duration of the acceleration increase can be determined, enabling regulation of the yarn fluid flow rate based on the acquired data.

This also has a beneficial environmental impact, as less thread fluid needs to be consumed, which can also reduce the corresponding costs for the production of the winding spool.

The method and device according to the invention are explained in more detail below with reference to some exemplary embodiments of the method and the device and the accompanying figures.

In 1 A schematic longitudinal view of a winding device 1 with a first embodiment of a wetting control 43 according to the invention for the delivery quantity Q with a first wetting device 4 for providing a first thread fluid 40 is shown.

The in 1 The illustrated winding device 1 has a first chuck 30 and a second chuck 31, which are movably held in a rotatable chuck turret 34.

In the 1 In the position shown, the first chuck 30 is in a winding position in which a winding coil 3 can be wound, and the second chuck 31 is in a doffer position in which the fully wound winding coils 3 can be removed from the respective chuck 30, 31.

The respective chuck 30, 31 is moved into the doffer position or the winding position by means of the chuck turret 34. The chuck turret 34 has a turret drive 35, which is controlled by the control unit 18.

Empty, unwound winding sleeves 2 are shown on the second chuck 31. The winding sleeves 2 are detachably mounted at the first to n-th changing positions 7.1 to 7.n on the first chuck 30 and the second chuck 31, respectively.

The first and second chucks 30, 31 each have their own first chuck drive 32 and second chuck drive 33 respectively, by means of which the respective speed of the first and second chucks 30, 31 can be controlled and regulated independently.

The first chuck drive 32 and the second chuck drive 33 are controlled by a control unit 18, in which the associated programs and control chips are housed.

The control unit 18 communicates with the first chuck drive 32 and the second chuck drive 33 via a communication line 5. The communication line 5 can be wired. However, communication can also be wireless via suitable radio systems.

To improve the winding of the filament bundle F onto the winding sleeve 2, a movable contact roller 8 is provided, which is movably mounted on a machine frame 10 of the winding device 1 via contact roller support arms 80.

The contact roller 8 is in contact with the winding sleeve 2 or with the filament bundle F wound onto the winding sleeve 2 and supports the winding of the filament bundle F.

The contact roller 18 is arranged downstream of a changing device 7 in the direction of a filament bundle thread travel direction FR.

A corresponding changing device 7 is provided at each changing position 7.1 to 7.n. The changing device 7 can, for example, have a birotor – with two counter-rotating rotors – by means of which the filament bundle F can be changed or moved back and forth along the longitudinal direction of the winding sleeve 3 and pressed onto the winding sleeve 2 by the contact roller 8.

The rotation or speed DK of the contact roller 8 through the winding sleeve 2 is detected and forwarded to the control unit 18.

The changing device 7 changes the thread or filament bundle F back and forth in a so-called changing triangle 70. The base or lower changing triangle area corresponds approximately to the width of the winding stroke and also to the width of the winding sleeve 2 onto which the filament bundle F is wound.

The changing device 7 also has its own changing drive 74. The changing drive 74 is also in contact with the control unit 18 of the winding device 1 and is regulated or controlled accordingly.

In order to bring the majority of filament bundles F to the respective changing position 7.1 to 7.n, movable thread distribution guides 72 are provided which are movable in a thread guide rail 73, or which can supply filament bundles F to the corresponding contact position or changing position 7.1 to 7.n.

Before the filament bundles F are fed to the changing device 7, fluid wetting devices 41 are assigned to each individual filament bundle F. A filament fluid 40 can be applied to the filament bundle F using the fluid wetting device 41. The fluid wetting devices 41 can be movable, so that they can be positioned as with the filament distribution guides 72.

Each fluid wetting device 41 is connected to a supply line 45. The supply line 45 is fluid-tight and connected to a fluid pump 42. The fluid pump 42 pumps the filament fluid 40 from a fluid reservoir 44 to the fluid wetting device 41.

The pumping capacity of the fluid pump 42 is controlled by a wetting control 43, which evaluates the data of the winding device 1 and regulates the fluid pump 42 accordingly.

The wetting control 43 is connected to the control unit 18 of the winding device via a communication line 5.

For transporting and unwinding the filament bundles F from a melt spinning device, at least one first galette 12 and one second galette 14 are positioned on a galette carrier 11. The first galette 12 and the second galette 14 each have their own galette drive 15, 16, as shown in 3 shown in a side view of the winding device 1.

A swirling device 13 is provided between the first galette 12 and the second galette 14. The swirling device 13 is designed to swirl or form tangled knots in the respective filament bundle F, so that the filaments of the filament bundle F become tangled or intertwined with each other and form a thread F that does not separate back into its individual filaments. It also serves to improve post-processing and further processing of the filament bundle F.

Additionally, a camera 50 can be provided in the winding device 1. The camera 50 can also detect the coil growth or the diameter of the winding coils 3 and provide this information to the control unit 18 via communication lines 5.

Corresponding programs are stored in the control unit 18 in order to perform a corresponding evaluation of the optical signals from the camera 50.

The camera 50 is optional and not mandatory. The diameter of the winding coil 3 is preferably determined via the rotational speed of the respective chuck 30, 31, or the rotational speed of the contact roller 8.

For example, the energy consumption of the associated drives of the respective components can also be used for an evaluation or determination of the diameter of the winding coil 3.

2 schematically shows a longitudinal view of a winding device 1 with a second embodiment of the wetting control according to the invention for providing the corresponding delivery quantity Q of a second thread fluid 60.

The in 2 shown features, which correspond to the features of 1 correspond to those with the same reference symbols. 1 displayed. The following section discusses the features that are not shown. 1 are known. The difference to the embodiment of 2 to the in 1 The feature is that a second wetting device 6 is provided locally above a galette carrier 11. The second wetting device 6 is preferably located near a melt spinning device (not shown) through which the respective filament bundles F are extruded from a polymer melt. The second filament fluid 60 provided by the second wetting device 6 can have different properties and compositions than the filament fluid 40 provided by the first wetting device 4.

The thread fluid 60 of the second wetting device 6 serves to prevent electrical charging. Additionally, the preparation oil 60 can reduce friction and improve the bundling of individual filaments into a filament bundle F.

The second wetting device 6, similar to the first wetting device 4, has a second fluid pump 62 for pumping the second thread fluid 60 from a second fluid reservoir 64. The second thread fluid 60 is stored in the second fluid reservoir 64. The second thread fluid 60 can also be a preparation oil.

In an embodiment not shown, the thread fluid 60 can also originate from the fluid reservoir 44 of the first wetting device 4 and vice versa.

The fluid pump 62 has a second wetting control 63, which is connected to the control 18 of the winding device 1 via a communication line 5.

The required data from the control unit 18 of the winding device 1 are retrieved by the second wetting unit control 63. The filament fluid 60, delivered by the second fluid pump 62, is supplied to the filament bundle F via a second fluid wetting unit 61.

In 2 The first wetting device 4 is shown as a dotted line. The dotted line represents a possible retrofit of the first wetting device 4.

The first wetting device 4 can also be omitted entirely. The function can also be performed by the second wetting device 6. The flow rate of the thread fluid 40, 60 can also be controlled via the second wetting device control 63 or the first wetting device control 43. The first or second wetting device control 43, 63, regulates the flow rate Q of thread fluid 40, 60 by evaluating data.

3 shows a side view of the winding device 1 from 1 or 2 .

Out of 3 It is particularly evident that the chuck turret 34 is rotatably mounted in the machine frame 10 of the winding device 1. This allows the respective chuck 31, 30 to be moved into a winding position and/or a doffer position. Furthermore, in the winding position, additional thread fluid 40, 60 can be applied to the filament bundle F via the first or second wetting device 4, 6, respectively, via the first fluid wetting device 41 or the second fluid wetting device 61, thus ensuring sufficient wetting of the winding core 2.

In 4 and 5 A winding sleeve 2 is shown in a partial sectional view or in a cross-sectional view. 1 The winding sleeve 2 is wound with a winding coil.

As in 4 As shown, the winding sleeve 2 has a first winding sleeve end section 20 and a second winding sleeve end section 21. The winding sleeve 2 has a wall 23 and can be mounted on the first or second chuck 30, 31.

To capture the filament bundle F, the winding sleeve 2 has a capture window 24. The capture window 24 has a capture section 26 for capturing the thread and a clamping section 27 for clamping the thread or filament bundle F in the winding sleeve 2.

The captured filament bundle F is wound onto the spool 3 via a so-called filament reserve 9. The filament reserve 9 at the capture window 24 is preferably not additionally wound with further filament layers, so that the filament bundle F in the filament reserve 9 can always be used for further processing, for example, to connect a first spool 3 to a second spool 3 during texturing.

Furthermore, in 4 The starting diameter DS of the winding coil 3 and the winding coil diameter DW are shown. In the illustrated embodiment of the winding coil 3, the winding sleeve 2 is also shown in its final diameter DE. When the winding coil 3 reaches the final diameter DE, the respective chuck 30, 31 is moved into the doffer position so that the winding coil 3 can be removed from the chuck 30, 31.

During the changing process – a back-and-forth movement of the filament bundle F to wind it onto the winding tube – a diameter increase DZ takes place from the starting diameter DS to the final diameter DE.

In 5 The process of capturing the filament bundle F via the capture window 24 is shown. The winding sleeve 2 is rotated towards the filament bundle F via the associated chuck 30, 31. The filament bundle F is then captured via the capture window 24 and clamped to the winding sleeve 2. The unwindable filament bundle F is then cut accordingly.

6 schematically shows a block diagram of the process steps S1 to S5 for adjusting the delivery rate Q of thread fluid 40, 60.

In a first step S1, data from the winding device S1 are evaluated and fed to the respective wetting control unit 43, 63. Based on the determined data, the flow rate Q of filament fluid 40, 60 is controlled in step S2. The filament fluid 40, 60 is then fed to the fluid wetting unit 41, 61 via a fluid pump 42, 62, and in a step S3, the filament bundle F is wetted with the filament fluid 40, 60.

The data obtained from the winding device 1 can, for example, include the rotational speed DSPZ of a chuck 30, 31, the rotational speed DK of a contact roller, and/or the diameter DW or the diameter increase DZ of a winding coil 3. Additionally, the diameter of the winding coil 3 can be inferred from the energy consumption of the respective drives of the chuck 30, 31 or the contact roller 8. Furthermore, the diameter can be monitored by a camera 50 and evaluated accordingly, and the data can be transmitted to the respective wetting control 43, 63 for further control of the fluid pump 42, 62.

Preferably, in step S4, the diameter of the winding spool 3 is determined. In step S5, the diameter DW or the diameter increase DZ of the winding spool can be determined via the rotational speed of the chuck, the rotational speed of the contact roller, and/or the energy consumption of the respective drive of the chuck or the drive of the contact roller. The diameter increase DZ or the diameter DW of the winding spool 3 can also be determined using optical measurement data OMD from the camera 50. From the determined data, a rotational speed FDZ of the fluid pump 42, 62 and the acceleration of the rotational speed are determined so that the delivery rate Q of thread fluid 40, 60 can be controlled and supplied within a predetermined time window.
