The aim of the invention is to keep the operating costs as low as possible. For this purpose, a guide device and a lower stationary suction device are arranged below the thread shaft pin of the winding machine, the thread piece being gripped by the guide device in the thread section before entering the suction device and being supplied as a thread loop to the lower stationary suction device.
Description
The application is a divisional application of an invention patent application with the application date of 2018, 4 and 20, and the application number of 201880026819.1 (international application number: PCT/EP 2018/060190) and the name of 'method and equipment for splicing multiple spinning threads'.
Technical Field
The invention relates to a method for splicing a plurality of threads in a plurality of winding stations of a reel-up winder and to an apparatus for splicing a plurality of threads in a plurality of winding stations of a reel-up winder.
Background
When producing synthetic threads in a melt spinning process, it is conventional to spin a plurality of threads from a spinning nozzle alongside one another in a parallel manner in a spinning position. After the treatment of the threads for the thread type, they are wound into bobbins by winding spindles in a plurality of winding stations of the take-up winder. Such a melt spinning device is disclosed, for example, in WO 1999/037835A 1.
If a malfunction occurs in the process, a suction device is arranged below the spinning device, which continuously receives the thread produced by the spinning nozzle and discharges it to a waste container. This ensures that the extrusion of the thread at the spinning nozzle does not have to be interrupted.
Once the fault in the process has been remedied, the wire must be spliced again in the winding station of the reel-up. For this purpose, it is conventional to pick up the line sets by means of a manually guided suction gun and to guide the line sets by an operator for splicing. Thus, the operator must detach the line set from the stationary suction device and acquire it with a manually guided suction gun. The suction gun is then guided to the reel-up winder, so that an auxiliary device arranged at the reel-up winder picks up the thread group and feeds it to the winding station for splicing. In this regard, conventional methods currently used to splice multiple threads in multiple winding stations are very operationally intensive.
Disclosure of Invention
It is therefore an object of the present invention to provide a method and a device for splicing a plurality of threads in a plurality of winding stations of a reel-up winder, in which method and device the thread groups can be fed to the winding stations as quickly and reproducibly as possible.
Another object of the invention is to make the method and the apparatus for splicing a plurality of spun threads as automated as possible.
With the method according to the invention, this object is achieved in that the thread group is captured by the guide device in the thread section before entering the suction device and is fed as a thread loop to the lower stationary suction device located below the winding spindle.
The object is thus achieved by the apparatus according to the invention in that the reel-up winder has a lower stationary suction device below the winding spindles, and in that the lower suction device cooperates with a movable guide device, by means of which the thread groups received by the upper suction device can be fed as thread loops to the lower suction device.
The invention is based on the finding that the threads received by the stationary suction device are guided together at a convergence point in a ray-like manner when they are drawn out of the spinning nozzle. In this case, the individual wires are guided with a wire spacing that varies according to the height. In order to utilize this effect, the invention uses a lower stationary suction device below the winding spindle, in which the thread groups are taken up by the guide device. The guiding means directly grasp the thread group before entering the upper suction means in the part of the thread group where the thread has been guided almost in the form of a bundle. Once the thread groups have been transferred to the lower stationary suction device, the threads fed in a ray-like manner can advantageously be captured and spliced in the region of the winding station.
To this end, the apparatus according to the invention has a lower stationary suction device which is arranged below the winding spindle of the reel-up winder. In this case, the lower suction means cooperate with a movable guide means by means of which the line set received by the upper suction means can be supplied to the lower suction means as a line loop. In this case, no manual operation is required for splicing the thread groups in the winding stations of the winding-up machine.
In order to allow defined pick-up and capture of the string set by the lower suction device, according to an advantageous method variant, the strands of the wire loop are severed by a cutting device. In this case, the strand of string established between the upper suction device and the guide device is fed to the cutting device. The cutting device is therefore directly assigned to the lower suction device.
In order that the thread tension generated in the thread package during loop formation can be kept as small as possible, the guide device has a freely rotatable guide roller which is held on a movable roller carrier. Here, the line set may be guided on the guide device without sliding.
Since usually the line set requires an opposite resistance during severing, preventing any yielding of the line set, a development of the invention is preferred in which the guide rollers can be guided by the roller carriage between the collecting position and the acquisition position, and in which the guide rollers cooperate with the lower suction device in the acquisition position. In this way, the stationary environment can be used directly to improve severing and retrieval of the line set by the lower suction device.
In order to allow engagement in the line group from outside the winding station, the roller carriage is additionally formed by a pivot arm and a guide carriage, wherein the pivot arm is arranged on a vertically displaceable guide carriage, wherein the pivot arm carries the guide roller at a free end, wherein the guide carriage is guided along a guide rail by a carriage drive, and wherein the pivot arm is controllable by the pivot drive.
In order to be able to complete the operation of splicing the thread in the winding station, the reel-up winder has an auxiliary device by means of which the thread group can be caught in the thread section before entering the lower suction device and can be fed to the winding station. Due to the height difference between the lower suction device and the auxiliary device, the line spacing established between the individual lines of the line set can advantageously be used to allow selection of the lines for joining in the winding station.
The method according to the invention and the device according to the invention for splicing a plurality of threads in a plurality of winding stations of a take-up winder therefore offer the major advantage that relatively short interruption times can be achieved after a malfunction in the melt spinning process. The splicing of the threads in the winding stations of the reel-up winder can be carried out in an automated manner by means of a predetermined control algorithm. Thus, manual activities in the melt spinning process may only focus on the remediation of the fault.

Detailed Description
Fig. 1.1 and 2.1 schematically show an exemplary embodiment of the device according to the invention in several views. Fig. 1.1 shows the exemplary embodiment in a side view, while fig. 2.1 shows the exemplary embodiment in a front view. The following description applies to both figures without explicit reference to one of them. The exemplary embodiment is integrated in a melt spinning apparatus for producing a synthetic thread. The melt spinning device has a spinning apparatus 1, a cooling apparatus 2, a godet apparatus 5 and a take-up winder 6, which are arranged one below the other. In principle, it should be noted at this point that further processing units, such as finishing, mixing, texturing and/or crimping devices, can be included in such a melt-spinning apparatus. Also, the configuration of the godet apparatus 5 is by way of example.
The spinning device 1 has a heated spinning beam 1.1, which supports a plurality of spinning nozzles 1.2 on its underside. The spinning nozzles 1.2 are configured in this exemplary embodiment as so-called double nozzles, so that two threads are extruded from each spinning nozzle 1.2. The spinning nozzle 1.2 is connected to a spinning pump 1.3. The spinning pump 1.3 is configured as a multistage pump and is connected via a melt cross feed 1.4 to a melt source (not shown here), for example an extruder.
Below the spinning device 1, a cooling device 2 is arranged, which has a blower chamber 2.2 and a cooling channel 2.1. The cooling channel 2.1 can be formed, for example, by a cooling cylinder which is arranged in the blower chamber 2.2. The blower chamber 2.2 is connected to an air conditioning device (not shown here). The cooling channel 2.1 has air-permeable walls, so that the air-conditioning air flowing out of the blower chamber 2.2 enters the cooling channel 2.1 in order to cool the extruded strand. The cooling channel 2.1 is connected on its underside to a gravity channel 2.3. In the gravity channel 2.3, a common thread guide 3 is provided for each spinning nozzle 1.2 below the cooling channel 2.1. The threads extruded from the plurality of filaments are separated and combined into filament bundles, respectively, by a common thread guide 3.
Below the gravity channel 2.3, a godet unit 5 follows, which has a plurality of projecting godets 5.1 and 5.2 held on a carrier 5.4. The godet rollers 5.1 and 5.2 are each equipped with a godet roller drive 5.3 on the rear side of the carrier 5.4.
The carrier 5.4 of the godet unit 5 is supported on a frame 6.10 of the take-up winder 6.
The coiler winder 6 has a rotatably mounted winding turret 6.3 which carries two winding spindles 6.2 mounted in a projecting manner. The winding spindles 6.2 are connected to spindle drives 6.4. The winding turret 6.3 is rotatable via a turret drive 6.5, so that the winding spindles 6.2 can be pivoted alternately between an operating region and a switching region.
In the operating area, the winding spindles 6.2 cooperate with a plurality of winding stations 6.1. In the exemplary embodiment, a total of four winding stations 6.1 are formed on the coiler 6. The winding stations 6.1 have the same structure and each have a deflection roller 6.9 and a traversing device 6.7. A deflection roller 6.9 is arranged downstream of the godet device 5 in order to distribute the thread to the winding station 6.1. The traversing devices 6.7 each have one traversing element per thread for guiding the thread to and fro. In order to lay the thread on the circumference of the winding reel, a contact pressure roller 6.6 is provided, which runs parallel to the winding spindle 6.2.
In order to be able to pick up the extruded thread in the event of a malfunction, a stationary suction device 4 is arranged above the godet unit 5. The device, referred to here as the upper suction device 4, has a wire collector 4.3 in order to collect the wire set 9 and feed it to a waste container (not shown in greater detail here) via the suction opening 4.1 and the waste pipe 4.2 in the event of a fault message. For this purpose, the thread collector 4.3 is provided with a cutting blade 4.4, by means of which a thread end is produced on the thread group 9 in order to be sucked into the suction opening 4.1.
In order to splice the threads of the thread group 9 in the winding station 6.1, the winding-up winder 6 is equipped with a lower suction device 7. The lower suction device 7 is arranged below the winding spindle 6.2. The lower suction device 7 has a suction opening 7.1 and a waste conduit 7.2 which cooperate to pick up the line set and discharge the line set to a waste container. The suction opening 7.1 is provided with a cutting device 7.3. The cutting device 7.3 is preferably formed by one or more blades, which makes it possible to sever the line set with as little cutting resistance as possible.
The upper suction device 4 and the lower suction device 7 cooperate with the guiding device 8 in order to transfer the line set from the upper suction device 4 to the lower suction device 7.
In this exemplary embodiment, the guide means 8 are formed by a freely rotatable guide roller 8.1 which is held on a pivot arm 8.2. The pivot arm 8.2 is embodied pivotable transversely to the line travel direction via a pivot drive 8.3. The pivot arm 8.2 and the pivot drive 8.3 are arranged on the guide carriage 8.4. The guide carriage 8.4 can be moved back and forth on a vertically oriented guide rail 8.5 by means of a carriage drive 8.6. For this purpose, the guide rails 8.5 are arranged transversely with respect to the end sides of the coiler 6.
Fig. 1.1 and 2.1 show the melt spinning device in an operating situation in which the thread group 9 is continuously discharged via the upper suction device 4 to the waste container. The godet device 5 and the reel-up 6 are in splicing mode to be able to receive the thread groups 9. For this purpose, the movably held godet 5.1 of the godet unit 5 has been displaced into the splicing position, as is indicated by the dashed lines in fig. 1.1. The reel-up 6 has an auxiliary device 6.8, which is formed in this case by a movable roller carrier 6.8, which carries a deflection roller 6.9. The roller bracket 6.8 is held in the extended position (shown by the dotted lines). The guiding means 8 are now guided to the collecting position. In the collecting position, the guide carriage 8.4 remains in an upper position on the guide rail 8.5. The pivoting arm 8.2 with the guide roller 8.1 is pivoted via the pivoting drive 8.3 into the thread run of the thread arrangement 9, wherein the guide roller 8.1 captures the thread arrangement 9 directly in the thread section directly above the suction device 4. Once the line arrangement 9 has been guided around the circumference of the guide roller 8.1, the guide carriage 8.4 is activated by the carriage drive 8.6. The guide carriage 8.4 leaves the collecting position and is guided to the lower pick-up position at the lower end of the guide rail 8.5. In the process, a wire loop 9.1 is formed at the guide roller 8.1. The thread emerging from the spinning nozzle 1.2 is still received by the suction device 4 and wound around the guide roller 8.1. This situation is illustrated in fig. 1.1 and 2.1 by dashed lines.
Fig. 1.2 and 2.2 show the melt spinning device in a condition in which the lower suction device 7 has received and guided the thread pack 9. For this purpose, the guide device 8 is in the lower pick-up position, in which the thread group is fed on the guide roller 8.1 via the pivot arm 8.2 to the cutting device 7.3 and the suction opening 7.1 of the lower suction device 7. The cutting device 7.3 severs the strand of the wire loop 9.1 guided between the suction device 4 and the guide roller 8.1. In this case, the formed end is received by the suction opening 7.1 of the lower suction device 7 after the wire set 9 has been cut off. This state is shown in fig. 1.2 and 2.2.
The pivot arm 8.2 with the guide roller 8.1 is guided to an intermediate position. To splice the threads in the winding station 6.1, the auxiliary device 6.8 is now activated. The deflecting rollers 6.9 held on the movable roller carriers 6.8 are held offset to one another in the splicing position, so that by means of a simple pushing-in movement, the taking up of threads guided alongside one another at a certain thread spacing is selected and the threads are conveyed into the winding station. The vertical spacing between the auxiliary device 6.8 and the lower suction device 7 is adjusted such that there is a predetermined line spacing between the lines of the line set 9 in the region of the auxiliary device 6.8.
Finally, the godets 5.1 of the godet device 5 are transferred from the splicing position into their operating position, so that the melt spinning device is ready for the continuous production of a composite thread. Fig. 3 shows the melt spinning apparatus in a normal operating state. The wires of the wire set 9 are wound into a bobbin.
The auxiliary device for selecting a thread group during splicing in the winding station shown in the above exemplary embodiments is by way of example. What is important for the method according to the invention and the device according to the invention is the cooperation between the upper and lower stationary suction means with guide means adapted to form a wire loop. As the guide means, a wire guide or a wire rod may be used instead of the guide roller.
