Description

The The invention relates to a device for stripping, drawing and Winding synthetic threads in a melt spinning process according to the preamble of claim 1.

at The production of synthetic threads is general known that the synthetic threads in a spinning device parallel to each other from one polymer melt to one each Variety of filament strands extruded, cooled and be bundled. To the threads from the spinning device to draw, to stretch and to wind coils are the other devices are known, the at least one godet device, a treatment device and a winding device included. In this case, the threads are guided parallel to each other, from melt spinning to winding to maintain different thread distances are essentially through the devices and their division are determined. So first is in the spinning device between the threads each held a spinning distance, the essentially by the nozzle division of the spinneret packets is conditional. After cooling, the threads become merged into a substantially smaller one Treatment distance jointly deducted, stretched and treated to become. In the winding device is a winding distance between the To comply with threads, which essentially by the coil width the coils of the individual winding units is conditional.

In order to obtain the most compact possible facilities, the smallest possible thread spacings are set, in particular for drawing and treating the threads, so that, for example, the godet units with short overall lengths already carry a plurality of threads at the same time. For example, from the DE 100 53 073 A1 a generic device is known in which the treatment distance of the threads is set within the godet devices and treatment devices to <6 mm. However, such tight thread guides require, in particular when creating a group of threads a sensitive and secure leadership, which is usually performed by an operator by means of a commercial suction gun. Since the threads are received together via a suction opening of the suction gun, the threading in guide means with a narrow thread pitch for the operator is particularly problematic.

It Now is an object of the invention, a device for stripping, stretching and winding synthetic threads in a melt spinning process of the generic type to provide, in which even with small thread intervals safe operation guaranteed especially when creating a group of threads remains.

These The object is achieved according to the invention that at least one of the devices is a lighting means for Illuminating the guide means of the facility concerned assigned.

advantageous Further developments of the invention are characterized by the features and feature combinations the respective subclaims defined.

The Invention is characterized in that regardless of a room lighting of the site, in particular the guide means, the lead a group of threads with close thread spacing to each other, can also be switched off. It has It turns out that this is the threading of individual Threads in closely adjacent groove-shaped Guide means for an operator essential simplified. Due to the additional illumination of the guide means let the rays in a mouth the suction gun incoming threads through a simple Movement of the operator with close thread spacing to each other in the Insert guide means. The application process leaves by the operator with great precision because of the additional lighting both the individual threads as well as the guiding means recognizable in their position even at the smallest thread distances stay.

Around the additional illumination of the guide means depending on an operating condition to be able to, the development of the invention is particularly advantageous in which the illumination means a switching means is assigned and in which the switching means with a machine control connected is. Leaves over the machine control Thus, the switching means depending on the operating state to control to to turn the lighting means on or off. A manual operation is not mandatory. In addition, can be determined by color the lighting means directly to the operator from the outside indicate at a spinning position that reaches a certain operating state is and thus requires certain actions of an operator become.

in this connection In particular, the development of the invention has proven itself, in which a monitoring unit for monitoring the threads is provided and wherein the monitoring unit directly or indirectly via the machine control with the switching means connected is. Thus, in a thread break the lighting means Switch on directly to create a new one without delay to allow the threads.

Basically, however, there is also the possibility probability to link the switching means with a control panel, so that depending on the machine control by an operator optionally the lighting means is switched on or off.

According to one preferred development, the lighting means by a Group of light emitting diodes or by several groups of light emitting diodes educated. This allows the LEDs on one or be arranged on several lighting supports, the immediate associated with the guide means. So can the guide means even in a very compact arrangement be illuminated intensively. In addition, the lighting means are in smallest available installation spaces of the facilities integrated.

According to one Another variant of the invention are the illumination carrier arranged on a cover which, at a distance from the illuminating Guide means is arranged and the guide means shields from the environment. This is how the lighting can be integrate into existing device parts, without additional To require fasteners. Here you can Also, several lighting support together on a cover or be arranged on a plurality of cover means.

in principle However, there is also the possibility that in very inaccessible Guide means the lighting means for indirect lighting the guide means is used. This is the training of the invention is an alternative arrangement in which the illumination carrier or several lighting supports together at a distance a covering means are arranged and wherein the covering means as Reflector for reflecting the light beams generated by the light emitting diodes is trained. This also allows inaccessible areas illuminate advantageous for certain operating conditions.

Around a plurality of threads safely with close thread spacing to each other to be able to lead, is preferably the training executed the invention, wherein the guide means is formed by a groove belt of the godet device, which on the circumference several closely adjacent guide grooves for recording the threads has. This is a stripping and stretching the threads in small thread intervals in a compact Training of the grooving palette possible.

The Guide means of the treatment device can be formed by a Verwirbelungsdüse, which a A plurality of closely adjacent thread treatment channels for Has recording of threads. In this case, too simple threading of the illuminated thread treatment channels to allow the swirl nozzle is preferred formed in two parts by a bottom plate and a cover plate, wherein the bottom plate, the groove-shaped thread treatment channels having. In that regard, thread depths can be through a Threaded operator in a simple manner at the same time become.

The Inventive device will be below with reference to an embodiment with reference to the attached Figures explained in more detail.

It represent

1 schematically a view of a first embodiment of the device according to the invention

2 schematically a view of a guide means of a godet device of the embodiment of 1

3 schematically a view of a guide means of a treatment device of the embodiment of 1

In the 1 to 3 an embodiment of the device according to the invention is shown schematically. 1 shows the complete device in a side view and in the 2 and 3 are each partial views of in 1 illustrated device parts shown. The following description therefore applies to all figures insofar as no explicit reference is made to one of the figures.

In 1 Figure 3 shows schematically the device according to the invention for stripping, drawing and winding synthetic threads, as typically used in a melt spinning process. The structure and arrangement of the individual device components are exemplary in this case. Thus, the embodiment shown has a godet device 1 , a treatment facility 4 and a take-up device 9 , which are arranged to a threadline with each other. The device could, for example, be arranged below a spinning shaft of a spinning device in order simultaneously to remove freshly spun threads from the spinning device.

The for pulling off the threads 35 provided godet device 1 has a first groove grooved 2.1 and a second grooved-galette 2.2 on, which are partially entwined by the threads. The first Rillengalette 2.1 and the second grooved-galette 2.2 become cantilevered on a godet carrier 3 held. On the back of the godmother 3 are the groove galleries 2.1 and 2.2 each one drive supplied arranges to the galette coats of the grooved galleries 2.1 and 2.2 drive. The grooved galleries 2.1 and 2.2 are preferably driven at a differential speed to, for example, in a thread line between the groove belts 2.1 and 2.2 a stretching of the threads 35 to obtain.

To the threads 35 With the tightest possible thread spacing to be able to lead next to each other, have the godet coats of the groove belts 2.1 and 2.2 each per thread a circumferential guide groove. In 2 is a schematic view of the second grooved belt 2.2 shown. In the godet coat 30 are a total of four guide grooves 31 parallel to each other on the circumference provided. In each of the guide grooves 31 becomes one of the threads 35 partially threaded. The godet coat 30 is at a drive shaft 29 with a godet drive 28 connected. The godet drive 28 is on the back of the godmother 3 arranged, wherein the drive shaft 29 the godparents 3 penetrates. This could, for example, within the godet carrier 3 a bearing of the drive shaft 29 be educated.

Like from the 1 is apparent in the threadline between the first groove gallery 2.1 and the second grooved-galette 2.2 a treatment facility 4 intended. The treatment facility 4 is as a vortex nozzle 5 formed, which has a thread treatment channel per thread.

In 3 this is a cross-sectional view of the swirl nozzle 5 shown. The swirl nozzle 5 is through a floor plate 6 and a cover plate 7 educated. The cover plate 7 is movable with the bottom plate 6 connected. The bottom plate 6 contains a total of four thread treatment channels 8th , which are groove-shaped at the top of the bottom plate 6 are introduced. In each of the thread treatment channels 8th opens a nozzle bore 36 passing through a distribution chamber 33 with a compressed air line 32 are connected. The through the guide grooves 31 the Rillengalette 2.1 and 2.2 predetermined thread spacing between the threads 35 is equal to the distance between the thread treatment channels 8th the vortex nozzle 5 so the threads 35 in parallel run side by side. The swirl nozzle 5 is about a holder 34 at the godet bearer 3 arranged.

How out 1 the galette bearer is revealed 3 for receiving the godet device 1 and the treatment facility 4 on an upper platform 10 the winding device 9 arranged. The winding device 9 has a machine frame 25 on top of that, the upper platform 10 forms and the device objects for a total of four winding units 12.1 to 12.4 contributes to the thread group consisting of four threads 35 simultaneously to coils 17 wind. This is in every winding unit 12.1 to 12.4 a pulley 11 , a traversing device 14 , A pressure roller extending over all winding units 15 and two winding spindle guided alternately in a winding area 13.1 and 13.2 provided on which the coils 17 are wound at the same time.

Around the winding spindles 13.1 and 13.2 to run alternately in the winding area, is a winding turret 16 provided by rotation of the winding spindles 13.1 and 13.2 alternately leads from the winding area into a changing area.

In the transition area between the godet device 1 and the winding device 9 the threads are at a front end of the take-up device 9 through the grooved hall 2.2 diverted and after the expiry of the grooved 2.2 directly to the pulleys 11 guided and on the individual winding units 12.1 to 12.4 distributed.

This in 1 illustrated embodiment is thus particularly suitable to be combined directly with a spinning device. In order to protect the device parts against falling polymer residues, especially during piecing, is on the godet carrier 3 a shielding agent 26 arranged. The shielding agent 26 is sheet-shaped and extends over the cantilevered guide means of the godet device 1 and the treatment facility 4 , To enable a thread withdrawal from a spinning device, the shielding means 26 with corresponding recesses for the passage of the threads 35 executed.

Like from the 1 . 2 and 3 As can be seen, are at the bottom of the shielding 26 a lighting means 18 provided to the guide means of the godet device 1 and the guide means of the treatment device 4 illuminate. The lighting means 18 This is done by several lighting support 19 each formed a group of light-emitting diodes 20 exhibit. The light-emitting diodes 20 are with a switching means 21 connected, through which the light-emitting diodes 20 optionally switched on and off.

So goes for example from the 2 that's just above the grooved line 2.2 a group of light emitting diodes 20 is provided to the guide grooves 31 on the circumference of the godet mantle 30 illuminate. The lighting carrier 19 the light-emitting diodes 20 is with the cover 26 firmly connected.

For illuminating the guide means of the treatment device 4 is in 3 shown that above the open swirl nozzle 5 also a group of light-emitting diodes 20 by means of a illumination carrier 19 are held such that when the bottom plate 6 the groove-shaped thread treatment channels 8th through the LEDs 20 are lit up.

Like in the 1 is shown, the the guide means of the godet device 1 and the treatment facility 4 associated light-emitting diodes 20 together via the switching means 21 controlled. Basically, however, there is also the possibility of the light-emitting diodes 20 To control groups separately and independently of the adjacent group of light emitting diodes via a separate switching means.

The switching means 21 is with a machine control 22 connected. This can be done via the machine control 22 Signals for activating or deactivating the switching means 21 create and give up. The machine control 22 is with other control devices not shown here the godet device 1 , the treatment facility 4 and the winding device 9 coupled. Furthermore, in the threadline of the threads 35 a monitoring unit 23 provided by a signal line with the machine control 22 connected is. The monitoring unit 23 can be integrated within the threadline at any point to monitor possible thread breaks or possible winding formations. Preferably, the monitoring unit 23 in the area between the take-up device 9 and the godet device 1 arranged. In this embodiment, the monitoring device 23 by way of example on the inlet side of the godet device 1 intended.

The machine control 22 It is also about a control line with a control panel 24 coupled. The control panel 24 is on a front side of the machine frame 25 held and over several lines not shown here with the control units and actuators of the godet device 1 , the treatment facility 4 and the winding device 9 coupled.

At the in 1 to 3 As shown, it is customary at the beginning of the process to use the synthetic threads 35 after piecing initially by an operator by means of a suction and then into the guide means of the downstream facilities 1 . 4 and 9 threading. In this operating state is via the machine control 22 previously the switching means 21 for switching on the LEDs 20 activated. The switching means 21 However, alternatively, it could be directly via the control panel 24 be manually activated by the operator. By illuminating and illuminating the guide means 2.1 . 2.2 and 6 can be immediately recognized by an operator at which points the threads are to be threaded. Furthermore, the threads, which are guided side by side with very little distance, can be threaded in a simple manner into the illuminated guide means. The individual threads and the associated guide means are clearly visible and can be combined with each other.

Once the threads are applied 35 in the godet setup 1 , the treatment facility 4 and the winding device 9 is completed, the switching means 21 to turn off the lighting means 18 disabled. During operation, the light-emitting diodes thus remain 20 switched off. The switching on and off of the lighting means can advantageously be regulated by a timer. However, it is also possible to serve the switching off of the illumination by a control lever for activating subsequent process steps.

In the case that the monitoring unit 23 detects a thread break and thus a restart is required, the signal of the monitoring unit can be 23 preferably in the machine control 22 use it directly to the switching means 21 to turn on the light emitting diodes. Alternatively, however, there is also the possibility that the signal of the monitoring unit 23 directly to the activation of the switching means 21 is used as in 1 shown in dashed lines. Thus, immediately after finding a thread break additional signaling can initiate to request an operator to re-create.

at Use of several separately controllable groups of LEDs There is also the possibility of a chronological order Turning on and off certain operations visible close.

In cases where critical areas of the thread guide and Fadeneinfädelung can not be directly illuminated by the illumination means, there is also the possibility that lighting means to combine together with a reflector. For example, the first grooved-galley 2.1 at a distance to the wrap a reflector 27 assigned. Above the reflector 27 is a lighting carrier 19 with a group of light emitting diodes 20 held. To illuminate this can be through the LEDs 20 generated light over the reflector 27 lead in the area which is particularly critical for threading the threads. The reflector 27 at the same time acts as a covering to the environment of the grooved 2.1 ,

All other areas of the device are illuminated by a room lighting the environment. Thus, such devices are usually assembled into complete systems to a variety of synthetic threads in one Make a plurality of spinning stations parallel to each other. In a spinning station ten, twelve or even more threads can be withdrawn as a group of threads, treated and wound up. In that regard, such halls are set up with bulbs that illuminate the entire device part. The device according to the invention thus offers the particular advantage of additionally illuminating critical guide means in the case of a particularly compact and narrow thread guide. The integration into the control sequence of the machine represents particularly advantageous ways of facilitating the operation of the entire machine.
