Description

The invention relates to a method for winding a continuously incoming thread according to the preamble of claim 1 and a Winding device for winding a continuously tapered Thread according to the preamble of claim 7.

A winding device is known from DE 43 34 813 (Bag. 2049), in which an incoming thread is wound on a driven sleeve becomes.

The sleeve is clamped between two centering plates. The centering plate are rotatably attached to a spool holder. The sleeve is in contact a drive roller and is driven by this. After the sleeve has reached a predetermined winding speed, the thread of one Catch groove, which is attached in the peripheral region of a centering plate, caught and severed, the loose thread end by a suction device is recorded. After the thread in the side next to the winding area a so-called thread reserve winding was wound on the core, starts winding the spool. To catch and start the Thread passed through a movable auxiliary thread guide before the thread is released for the actual winding trip.

Such winding devices are used, for example, in texturing machines used to wind a textured thread into a spool. in this connection becomes the continuously tapering thread before catching and tackling on the empty tube taken over by a suction device. The suctioned thread is fed to a waste container. Therefore, the aim is the time during which the thread is guided in the suction device will be kept as short as possible - that is, with every spool change.

EP 0 311 827 shows a method and an apparatus in which which thread during a bobbin change by means of a Stepper motor driven traversing thread guide is guided. in this connection there is no need to hand over the thread after catching and winding Traversing device. However, this method and device also have this the disadvantage that the bobbin change phase during the thread drop arises, takes a relatively long time.

DE 42 26 364 discloses an open-end spinning device with a winding process or a winding device 7 according to the preamble of claims 1 and 7 respectively.

Accordingly, it is an object of the invention, a method and a winding device of the type mentioned in such a way that the Amount of waste of the continuously running thread before catching and Wrapping on a sleeve is minimized. Another object of the invention is to catch the thread with high security before winding.

This object is achieved according to the invention by a method with the features according to claim 1 and by a device with the features solved according to claim 7.

The invention is characterized in that the thread without a time delay immediately after reaching the winding speed required for winding caught by a catching device and wound on the sleeve becomes. For this purpose, the speed of the sleeve is continuously recorded. As soon as one predetermined thread speed is reached, the drive of the thread guide activated. The thread guide then leads to catching the thread and Winding the thread on the sleeve corresponding movements. The Spindle speed corresponds to the speed of the sleeve, which is a peripheral speed generated on the sleeve, which is substantially equal to the Thread speed is.

However, the invention also offers the possibility that the sequence of movements the thread guide is still placed in the acceleration phase of the sleeve. This is particularly advantageous in cases where the thread is in the Catcher initially on a larger diameter than the sleeve diameter is caught. Therefore, in order to adhere to an essentially constant winding speed of the thread with the speed of the Sleeve rotating safety gear with a lower speed than that Spool speed be driven while catching.

A particularly advantageous method variant according to claim 2 has the Advantage that the thread is reached immediately without significant delay a catching position of the thread guide is caught by the catching device. Since the thread continues to be guided in the suction device until it is caught this variant leads to a further reduction in the amount of waste from the Thread.

In a further particularly advantageous method variant according to claim 3, the thread reserve winding when winding the thread on of the sleeve depending on the winding speed of the sleeve. In order to can be the number of turns on the sleeve surface as well as the length the thread reserve winding on the sleeve surface of the respective winding speed be adjusted. Furthermore, the process variant has the Advantage that the transfer of the thread from the thread guide to a traversing thread guide a traversing device is controllable.

A particularly advantageous development of the method according to claim 4 is characterized in that the thread in each phase when catching, is controlled controllably during winding and during winding. While the winding of the thread can do this the signal of the speed of the sleeve be used to control the traversing speed of the thread guide.

Furthermore, the method according to claim 4 can be expanded in such a way that that after winding the thread of the thread guide in a transfer position moved within the winding area to form a setting winding becomes. After wrapping the binding on the full spool, is the thread through a transfer device for cutting and Apply led to a suction device. This will be the end of the thread clearly visible on the full spool.

The method variant according to claim 5 leads to a particularly gentle thread transfer to a suction device, since the thread is none receives significant deflections that lead to significant changes in thread tension to lead.

The device according to the invention has a sensor that measures the speed the sleeve detects and the signal of the speed in the control device gives up, which controls the drive of the thread guide. This ensures that the movement of the thread guide only after reaching a predetermined Spindle speed is executed by the drive.

The development of the winding device according to the invention Claim 8 is particularly suitable to ensure safety when catching to increase the thread. In addition, the time during the thread becomes extreme is deflected in order to offer the thread of the catching device for catching, significantly shortened.

In a winding device according to the invention, in which the sleeve is stretched between two centering plates arranged on a spool holder and the catching device is formed on one of the centering plates, can according to claim 9, the speed of the sleeve and the position of the catch groove in the safety gear in a simple way.

It is particularly advantageous here if the sensor as claimed in claim 10 Pulse generator is executed. So that both the location and the Speed of the sleeve can be determined from the pulse train.

A particularly advantageous development of the winding device according to the invention according to claim 11 has the advantage that no additional Control unit for controlling the traversing device is required. All Operations during winding and during bobbin changes are controlled by a control device.

After the thread has been caught and wound on the core, the actual winding travel takes place, i.e. winding the spool. After this the bobbin is finished, the spool change is initiated Thread taken over by the suction device. The design of the The winding device according to the invention according to claim 12 offers the Advantage that a binding bead is wound on the full spool. For this are the suction device and the traversing thread guide are positioned in one plane, so that the thread end is safely placed on the binding winding becomes.

The execution of the winding device according to claim 13 offers the particular advantage that the spool change, i.e. the exchange of full Coil against an empty tube, immediately after the bobbin holder has come to a standstill. For this purpose, the signal generated by the sensor is used to change the device to activate.

Further advantageous developments of the invention are in the subclaims Are defined.

The method and the winding device according to the invention are based on some embodiments in the following with reference to the accompanying Drawings described in more detail.

They represent:

an inventive winding device with drive roller drive;
Fig. 3
the winding device of Figure 2 when winding.
Fig. 4
the winding device of Fig. 2 when changing the bobbin.

In Fig. 1 is a first embodiment of the winding device according to the invention shown. The device for winding a tapered Thread 1 has a winding spindle 12. The winding spindle 12 is cantilevered with the bearings 17 mounted on a machine frame. At the end of the camp the winding spindle 12 is connected to a spindle motor 16. On the A spindle 13 is stretched over the winding spindle 12. Axial parallel to the winding spindle 12 at a distance from the sleeve 13, a pressure roller 10 is arranged. The Pressure roller 10 is rotatably mounted with axis 11 in the machine frame. A traversing device is located above the winding spindle 12 and the pressure roller 10 22 attached in the machine frame. In this embodiment the traversing device 22 is designed as wing traversing the structure and function of which will be discussed later.

Between the traversing device 22 and the pressure roller 10 is a Guideline 9 arranged.

The sleeve 13 clamped on the winding spindle 12 has at one end a catching device 14. At the end of the sleeve 13 with the catching device 14 is a movable thread guide 18 above the winding spindle appropriate. The thread guide 18 is coupled to a drive 19 which the thread guide 18 in a parallel plane to the winding spindle 12 in the longitudinal direction to the sleeve 13 away from the sleeve end and back to the sleeve end emotional. The drive 19 is connected to a control device 8. in the The area of the winding spindle 12 is a sensor 20 for detecting the speed the winding spindle. The sensor 20 is connected to the control device 8 connected. Another sensor 25 is located in the area of the catching device 14 attached, which detects the position of the catch groove 21 of the catching device 14. The sensor 25 is also connected to the control device 8.

In Fig. 1 the operating situation is shown in which the thread 1, the continuously tapering over the head thread guide 2 to the winding device arrives, guided by the thread guide 18 on the sleeve 13. The thread 1 is already caught in the catching device 14 and is on the sleeve 13 wound for a thread reserve winding 15. Before the Catching the thread in the catching device 14 becomes the loose end of the thread by means of a hand-held suction device and the thread guide 18 guided. The thread guide 18 can be in a position within of the winding area or outside the winding area. after the Control device 8 from the sensor signal from the sensor 29 as well the sensor signal from sensor 25 has determined that the required Spindle speed of the sleeve 13 is reached and that the catch groove is just in is in a position that enables safe catching, the drive 19 activated. The thread guide 18 thus starts to move and leads the thread 1 in the area of the catching device 14. After the thread 1 of the sleeve is taken over, the thread guide 18 holds the thread for winding ready on the sleeve. After the thread reserve winding on the Sleeve is created, the thread is released by the thread guide 18 and falls into the traversing device. For example, the thread guide be axially pivotable.

The traversing device 22 is constructed as a so-called wing traversing. A traversing thread guide 7 developed as a wing is moved by means of a rotor 5 driven so that the thread 1 from the right spool edge is led to the left edge of the coil. Here the thread slides on the Guideline 9 along so that the position of the thread on the traversing thread guide does not change significantly. After thread 1 to the left edge of the bobbin is guided, the traversing thread guide 7 dips below the guide 9. As a result, the thread 1 is released and at the same time by the Guideline 9 of counter-rotating traversing thread guide 6 taken over and by means of the traversing thread guide 6 to the right end of the Led winding area. For this purpose, the traversing thread guide 6 by a Rotor 4 driven in the opposite direction. At the right end of the The bobbin repeats the thread transfer by the traversing thread guide 6 dips under the guide and the traversing thread guide 7 takes over the thread.

During the winding time, the pressure roller 10 lies on the circumference of the coil with an investor. With the help of the pressure roller, the drive 16 the winding spindle 12 controlled such that the winding speed in remains essentially constant during the winding time.

After the bobbin is completely wound, the bobbin spindle with the full bobbin pivoted from the operating position. A second, not shown here, The driven winding spindle with an empty tube is then in the operating position pivoted. Now a changing device intervenes, the Thread from the traversing and the thread together with the Thread guide 18 ready to catch on the new tube.

Such winding devices are used, for example, to keep fresh winding spun synthetic threads into bobbins.

2 is another embodiment of an inventive Winder shown, such as in a texturing machine can be used. In the description below, the Components with the same function labeled with identical reference numerals. On A pivot axis 41 arranged in the machine frame 40 is a coil holder 26 pivotally mounted. At the free ends of the fork-shaped bobbin holder 26 are two opposing centering plates 28 and 27 rotatably mounted. A sleeve 13 is located between the centering plates 28 and 27 tensioned to accommodate a coil. Is on the surface of the sleeve 13 a drive roller 29. The drive roller 29 is on a drive shaft 31 attached. The drive shaft 31 is at one end with the roller motor 30 coupled. The roller motor 30 essentially drives the drive roller 29 constant speed. The sleeve 13 is now over friction driven by the drive roller 29 to a winding speed, which is a winding of the thread at thread speed. The winding speed thus remains essentially constant during the winding cycle. A traversing device 22 is arranged in front of the drive roller 29. The Traversing device 22 is constructed as a so-called belt traverse.

Here, a traversing thread guide 6 is attached to an endless belt 33. The belt 33 is between two pulleys 34.1 and 34.2 guided parallel to the sleeve 13. In the belt level is one of the belts partially wrapped drive roller 35 parallel to the deflection rollers 34.1 and 34.2 arranged. The drive roller 35 is on a drive shaft 44 Electric motor 36 attached. The electric motor 36 drives the drive roller 35 oscillating so that the traversing thread guide 6 in the area between the pulleys 34.1 and 34.2 is moved back and forth. The electric motor 36 can be controlled via a control device 8. The control device 8 is connected to a sensor arranged on the coil holder 26 32, the catch groove 21 of the catch device attached to the centering plate 27 14 senses.

The sensor 32 is designed as a pulse generator, that per revolution emits a signal depending on the catch groove 21. These impulses are in the control device for evaluating the position of the safety gear and the speed of the sleeve 13 converted. The sleeve 13 is clamped between the centering plate 27 and 28 such that the centering plate Rotate 27 and 28 without slipping at the speed of the sleeve.

On the opposite side to the drive roller 29 for traversing a suction device 37 is arranged. The suction device is here a cutting device 38 and a suction connection 39.

In FIGS. 2 to 5, the winding device from FIG. 2 is different Operating situations shown. In Fig. 2 the is continuous fed thread guided by the suction device 37. This is the Thread end drawn into the suction port 39. Between the suction device 37 and the head thread guide, not shown here, becomes the thread 1 guided in the traversing thread guide 6. The traversing thread guide 6 is in Directed the centering plate 27 into an exchange position. This exchange position can be chosen such that the thread 1 in the region of the sleeve or is outside the area of the sleeve. The sleeve 13 is through the circumferential drive roller 30 to one by the drive roller predetermined spool speed driven. The sensor 32 generates each Passing the catch groove a pulse that the control device 8 gave becomes. The control device 8 has an evaluation device, which is the instantaneous speed from the impulses per unit of time the centering plate and thus the sleeve. At the same time everyone gives Impulse the location of the catch groove 21. After the sleeve 13 the winding speed reached and the catch groove a necessary for safe catching Has position, the electric motor 36 is controlled by the control device 8 activated. The electric motor 36 drives the traversing thread guide 6 out of the Change position in the area of the catching device 14. The thread 1 is caught with the catch groove 21 and with one in the catch device or the centering plate 27 integrated knife cut. Such a centering plate is known for example from EP 0 403 949. So far referred to the mentioned publication.

The traversing thread guide 6 changes from the catch position to the winding area guided. Here, the thread 1 on the sleeve 13 outside the winding area wound into a thread reserve winding. The formation of the thread reserve winding can be caused by someone stuck in a position Traversing thread guide 6 take place. Then the thread reserve winding has one Number of parallel windings. The traversing thread guide 6 can also at a speed determined by the motor 36 to the winding area be performed so that adjacent turns in the Thread reserve winding are generated. As soon as the thread guide reaches the winding area reached, the winding trip begins. The traversing thread guide is then inside the winding area through the traversing device 22 brought hither. This situation is shown in FIG. The growing coil diameter the bobbin 24 is moved by a pivoting movement of the bobbin holder 26 allows. For this purpose, the coil holder 26 has force transmitters (here not shown), the one required for driving the coil Generate contact pressure between the coil 24 and the drive roller 29 and on the other hand allow a pivoting movement of the bobbin holder 26.

4, the winding device is shown at the end of a winding trip. After the bobbin 24 has finished winding, the traversing thread guide becomes 6 moved into a transfer position. The remains in this transfer position Traversing thread guide 6. A binding winding is now on the bobbin 24 generated. At the same time, the coil holder 26 with the coil 24 from the Operating position swiveled. At the same time, a transfer device 42 occurs in action by placing a gripper arm 43 in the thread path between the full spool 24 and the traversing thread guide 6 engages. The gripper arm 43 is made a rest position pivoted into a transfer position. Here he grabs the thread 1 and leads the thread in the transfer position to the suction device 37. The thread is then cut in the cutting device 38 and taken from the suction port 39. The loose thread end will placed on the spool in the area of the binding winding. Now that can Coil 24 are replaced by an empty sleeve. Here it is from Advantage that the sensor is attached to the coil holder and thus the The standstill of the coil signals that there is no more pulse. The Sensor signal can thus be used to activate a changing device become. After the coil 24 has been replaced by a sleeve, the begins Sequence, as already described for FIG. 1, anew.

The method according to the invention and the winding device according to the invention can be easily converted into a rewinder further develop, in which several winding stations arranged one behind the other are. Each winding station can have a thread guide for guiding the Thread outside the bobbin area. The thread guides can driven by a drive or by individual drives become.

Likewise, the embodiment of FIG. 1 with a belt meandering - As shown in Fig. 2 - or a reverse thread shaft maneuvering be executed.

Furthermore, the winding spindle shown in Fig. 1 can also by a Drive the drive roller.

The winding device shown in FIGS. 2 to 4 can also be reversed with a traversing device and a separate thread guide for guidance equip the thread outside the winding area. The thread guide to Guiding the thread for catching and winding is advantageous in Moved longitudinally parallel to the sleeve. However, it is also possible to Thread guide 18 to move into the thread run by a pivoting movement. Wing traversing or reversing thread traversing can also be used as traversing devices be used.

All the previously described embodiments of the winding devices can be used to carry out the method and draw is particularly characterized by a time-optimized change phase. The during the The amount of waste produced during the change phase is reduced to a minimum.
