Description

On winding device

The invention relates to a winding device for continuously winding a thread or fiber strand according to the preamble of claim 1.

A generic winding device is known, for example, from EP 0 450 085 A1. Continuously supplied, for example produced in a manufacturing process threads or fiber strands or other endless strands are usually wound into coils for storage. For this purpose, automated winding devices are preferably used in order to be able to wind a plurality of bobbins after each other without substantial interruption. Such automated winding devices have at least two winding spindles which alternately wind the thread or fiber strand into a spool. In principle, the winding spindles can be held on a movable spindle carrier or stationary on a stationary spindle carrier. In both variants of the spindle carrier, it is necessary that after completion of a coil on one of the winding spindles of the thread or fiber strand must be transferred to the adjacent winding spindle, so that a new coil can be formed. The transfer of the thread or the fiber strand can be carried out in the variant with a movable spindle carrier in a simple manner such that the positions of the winding spindle are reversed by movement of the spindle carrier. In that regard, the variant of the winding device with two drivable winding spindles has prevailed on a movable spindle carrier in practice. The spindle carrier is preferably designed as a winding turret, so that a thread transfer after completion of a coil can be performed by simple rotation movement of the winding turret. For the success of the transfer of the thread or the fiber strand is essential that the thread or the fiber strand of taken over the winding spindle or a cooperating with the winding spindle catching device and a severing of the thread in the thread section between the full bobbin and the thread or the fiber strand taking over the winding spindle. For this purpose, a plurality of auxiliary devices are known in the art, which are guided via additional actuators for yarn guide and thread separation between the winding spindles. In that regard, complex controls are needed to coordinate the movement in the transfer of the thread or the fiber strand.

From EP 0 450 085 AI a spooling device of the generic type is known, in which the auxiliary equipment required for yarn transfer are fixedly arranged on the winding turret and are automatically included by rotation of the winding turret to the transfer process of the thread or fiber strand. For this purpose, the winding spindles are each assigned two separating devices and two catching devices. The necessary in the transfer of the thread or fiber strand positioning of the thread is done exclusively by a movable traversing yarn guide, which is positioned parallel to the winding spindle outside a traverse stroke. The transfer of the thread or fiber strand from a winding spindle with a full roll to the other winding spindle can thus be carried out solely by rotational movement of the winding turret. The separator is formed by a fixed cutting edge, which is held on the Spulrevolver. However, such cutting edges require a certain delay of the thread or the fiber strand between the winding spindles to make a defined and clean separation of the thread or fiber strand. In particular, when using fiber strands partial scabs can be carried out at insufficient yarn tension, which lead to defibration and Verfung the fiber ends. Furthermore, there is the problem that the time at which the fiber strand is severed is undefined, so that a severing of the fiber strand before its fixation and winding of a new coil could already occur and would result in a process interruption. These problems Tik is particularly in processes in which the thread or fiber strand is wound at relatively low speeds.

It is therefore an object of the invention to develop a winding device for the continuous winding of a thread or fiber strand of the generic type such that after completion of a full bobbin of the fiber strand is automatically cut through safely.

Another object of the invention is to provide a generic Aufspul- device for continuously winding a fiber strand, in which the transfer of the fiber strand between the winding spindles after completion of a finished wound full bobbin essentially without external energy by additional actuators executable.

This object is achieved by a winding device for continuously winding a thread or fiber strand with the features of claim 1. Advantageous developments of the invention are defined by the features and feature combinations of the subclaims.

The invention is characterized in that during the transfer of the fiber strand between the winding spindles after completion of a full bobbin of the fiber strand is severed only after reaching a minimum yarn tension. Thus, on the one hand, it is ensured that the fiber strand is grasped at the winding spindle which takes over the fiber strand, so that a minimum yarn tension can be generated in the yarn section between the full bobbin and the take-up winding spindle. For this purpose, the winding spindle associated separating devices are each formed with a knife and a knife associated with the blocking means, wherein the fiber strand is passed through the barrier means before severing and wherein the fiber strand causes a release of the locking means upon reaching a minimum tensile force and the knife is fed. The minimum train By virtue of the fiber strand, it is preferably chosen such that an immediate severing of the fibers is effected when the fiber strand meets the knife. This advantageously avoids fretting and splicing at the ends of the thread.

So that a recurrent transfer and severing of the fiber strand from the rotary turret held separating devices in a simple manner can be carried out safely in a simple manner solely from the rotational movement of the winding turret, the blocking means is preferably formed by mechanical means. Thus, according to an advantageous development of the invention, it is provided that the knife is associated with a groove bottom of a guide groove and that the blocking means is formed by a rocker arm, which covers the groove bottom of a guide groove and which upon reaching the minimum tensile force of the fiber strand through the groove bottom of the guide groove opens a fold away.

To comply with an actuation force of the rocker arm, which corresponds to the minimum tensile force of the fiber strand, a force transmitter is preferably used, which cooperates with the rocker arm. According to a further development of the invention, it is proposed for this purpose that the rocker arm is formed by a holding arm and an arm arranged at an angle to the arm and that the rocker arm is mounted on a pivot axis, wherein a force transmitter acts on the arm and wherein on the guide arm of the Fiber strand is feasible. In this case, leverage ratios can advantageously be used to allocate a relatively smaller or larger holding force to the rocker arm of the actuating force. The actuating force of the rocker arm is determined by the yarn tension of the fiber strand, which acts on the guide arm. In contrast, a holding force can be generated via the force transmitter on the holding arm.

As a power transmitter, the use of a permanent magnet has proven particularly useful, which fixes the metallic support arm with a magnetic holding force. As soon as the tension caused by the thread tension of the fiber Stranges generated actuating force on the guide arm, taking into account the lever geometry overcomes the magnetic holding force, the rocker arm with its arm automatically releases from the permanent magnet and the folding away of the rocker arm to release the guide groove sets.

In order to obtain a desired yarn path of the fiber strand in the transfer of the fiber strand between the winding spindles, is provided according to an advantageous development of the invention that the winding volver offset by 180 ^° to each other arranged support rods and two offset by 180 ^° to each other guide rods, wherein during the transfer of the fiber strand one of the support rods and one of the guide rods lead the fiber strand between the two winding spindles. Thus, there is the possibility that, on the one hand, the supply of the fiber strand to the full bobbin and the shrinkage of the fiber strand into a catching device can be guided independently of one another. Thus, it is provided that the support rods in each case influence the yarn path of the fiber strand to the full package and the guide rod the yarn path of the fiber strand to the capture device.

Since a waste of the fiber strand from the circumference of the full bobbin must be avoided in the transfer of the fiber strand between the winding spindles, the support rods each have a free end extending parallel to the winding spindles over a coil center and each have a thread holder, which has a Positioning of the fiber strand causes on a support rod.

The arrangement and design of the support rods and guide rods are independent of the design of the respective catcher, so that the fiber strand could be trapped for example by a clamping slot on the circumference of the winding tube. In order to use possible winding tubes with smooth surfaces, the catching device is preferably formed by a plurality of fishing hooks, which are held distributed immediately adjacent to the winding tube on the circumference of the respective winding spindle. Thus, all positions and guides of the fiber strand can be made independently of the winding tube used in each case. The feed of the fiber strand is determined exclusively by the positionable traversing yarn guide.

For the supply of a fiber strand, in particular the development of the invention has been proven in which the traversing yarn guide is formed by at least two pairs of rollers which are aligned orthogonal to each other. Thus, the fiber strands can be supplied as a flat band of the winding device. By a rotation of 90 ^° over the two pairs of rollers so there is the possibility to wrap the fiber strand band-shaped on the circumference of the coil.

To position the traversing yarn guide, the pairs of rollers are preferably attached to a holder that can be positioned via a drivable threaded shaft. This can be controlled by driving the threaded shaft both a traversing movement of the roller pairs and a positioning for the transfer of the fiber strand. For filing the sliver on the circumference of the coil further Chanigerfadenführer a pressure roller is assigned, which is held by a movable rocker on the circumference of the coil to be wound. The mobility of the pressure roller can be used to advantage to perform an evasive movement of the winding spindle by a rotational movement of the winding turret with increasing coil. For this purpose, a sensor for monitoring the position of the pressure roller is provided, which is coupled via a control device with a turret drive of the winding turret. The spooling device according to the invention will now be described with reference to an embodiment with reference to the accompanying figures.

1 and 2, an embodiment of the invention on spooling device is shown in several views. Fig. 1 shows the embodiment in a front view and Fig. 2 in a plan view. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The embodiment of the spooling device has a Spulrevolver 2, which is rotatably mounted in a Ge partition wall 1 and is rotatable counterclockwise via a turret drive. The winding turret 2 carries two rotatably mounted winding spindles 3.1 and 3.2, which are held projecting, each with a free end. The winding spindles 3.1 and 3.2 are held on the Spulrevolver 2 offset by 180 ^° to each other. Each of the winding spindles 3.1 and 3.2 is coupled in a drive which, as shown in FIG. 2, could be formed, for example, by a respective spindle drive 19.1 and 19.2.

The winding spindles 3.1 and 3.2 each carry a winding sleeve 5.1 and 5.2, on the circumference of a coil can be wound. Each of the winding spindles 3.1 and 3.2 has a catching device 4.1 and 4.2, which are arranged laterally next to the winding tube 5.1 and 5.2 on the circumference of the winding spindle 3.1 and 3.2 in the region of the bearing end of the winding spindle 3.1 and 3.2 as shown in Fig. 2. The catching devices 4.1 and 4.2 on the winding spindles 3.1 and 3.2 are identical, so that at this point only the capturing device 4.2 of the winding spindle 3.2 is described. The fishing device 4.2 has a plurality of fishing hooks 40, which are distributed uniformly on the circumference of the winding spindle 3.2. The catch hook 40 is assigned to the circumference of the winding spindle a catching groove 39 which has a width which is greater than the catch hook 40 projecting into the catching groove 39.

As can be seen from the illustration in FIGS. 1 and 2, each winding spindle 3.1 and 3.2 are each assigned a separating device 7.1 and 7.2, a guide rod 23.1 and 23.2 and a holding rod 22.1 and 22.2. The separating devices 7.1 and 7.2, the guide rods 23.1 and 23.2 and the support rods 22.1 and 22.2 are arranged distributed between the winding spindles 3.1 and 3.2 and firmly connected to the winding turret 2.

As can be seen from the illustration in FIG. 2, the separating devices 7.1 and 7.2 are held by a respective support 28.1 and 28.2 in a catching plane, which is clamped by the catching devices 4.1 and 4.2.

The support rods 22.1 and 22.2 and the guide rods 23.1 and 23.2 are different lengths projecting on the Spulrevolver 2 arranged. The longer support rods 22.1 and 22.2 protrude with a free end over a coil center, which is determined substantially by half the length of the winding tubes 5.1 and 5.2. Within a Spulbereiches, which is determined essentially by the length of the winding tube 5.1 and 5.2, the support rods 22.1 and 22.2 each have a yarn guide 24.1 and 24.2, which serves to position a sliding on the support rod 22.1 or 22.2 fiber strand.

The shortening guide rods 23.1 and 23.2 protrude with their free ends into the winding area of the winding tube 5.1 and 5.2 and cover the capturing devices 4.1 and 4.2. The structure and function of the separators 7.1 and 7.2 and the function of the support rods 22.1 and 22.2 and the guide rods 23.1 and 23.2 will be explained in more detail below.

As is apparent from the illustration in FIGS. 1 and 2, a traversing device 8 is held on the frame wall 1 projecting laterally next to the winding turret 2. The changer device 8 has a traversing yarn guide 9, which in this exemplary embodiment is formed by two pairs of rollers 15.1 and 15.2 arranged orthogonally to one another. The roller pair 15.1 is aligned transversely to the winding spindles 3.1 and 3.2 and takes over a fiber strand fed from a process. The second roller pair 15.2 arranged in the direction of yarn travel below the first roller pair 15.1 is held orthogonal to the first roller pair 15.1 and extends parallel to the winding spindles 3.1 and 3.2. The pairs of rollers 15.1 and 15.2 are held by roller supports 16.1 and 16.2, which are fixed together on a holder 17. The holder 17 can be moved back and forth parallel to the winding spindles. For this purpose, the holder 17 is guided over a threaded shaft 13 which extends parallel to the winding spindles 3.1 and 3.2. The threaded shaft 13 is rotatably mounted on a cantilevered traverse support 14 and coupled at one end with a traction drive 18.

As can be seen in particular from the representation in FIG. 2, the holder 17 can be positioned on the threaded shaft 13 such that the pairs of rollers 15.1 and 15.2 can be positioned laterally next to the winding area. In the position shown in Fig. 2, the traversing yarn guide 9 of the traversing device 8 is outside a traverse stroke and allows positioning of the fiber strand in a trapping plane to catch the fiber strand in a transfer from a full bobbin to an empty winding tube.

In operation, the holder 17 is reciprocated on the threaded shaft 13 within a traverse stroke, which is preferably somewhat smaller as the width of the winding tubes 5.1 and 5.2. Thus, the coil area on the circumference of the winding tubes 5.1 to 5.2 is determined by the traversing stroke. As is apparent from Figures 1 and 2, the traversing device 8 is associated with a rotatably mounted pressure roller 10, which applies to the circumference of the winding tube 5.1 or when winding a fiber strand on the circumference of the wound coil. The pressure roller 10 is held by a fork-shaped rocker 11, which is pivotally mounted on a auskrangenden pivot axis 12. The rocker 11 is associated with a sensor 25 which detects a deflection movement of the pressure roller 10 during the winding of a coil. In this case, the deflection movement of the pressure roller 10 is used in order to perform a further indexing of the winding turret 2 for winding a coil at a substantially unchanged position of the pressure roller 10 can. The sensor 25 is for this purpose coupled to a control device 20 which, as shown in FIG. 2, is coupled to the drives 19.1, 19.2, 21 and 18.

The winding device shown in FIGS. 1 and 2 is suitable for continuously winding a thread or fiber strand into a bobbin, wherein the bobbins are formed alternately on the winding spindles 3.1 and 3.2. After completion of a coil, the transfer of the fiber strand from a full bobbin to the adjacent winding spindle is carried out solely by the rotational movement of the winding turret and the positioning of the traversing yarn guide. Such a situation is shown in FIG. For the transfer of the fiber strand from the full bobbin 6 to the winding spindle 3.2, it is necessary that the fiber strand in the thread section between the winding spindle 3.2 and the full bobbin 6 is severed. In order to obtain a safe transfer and separation of the fiber strand despite low winding speeds, each of the separators 7.1 and 7.2 is identical. In the following, therefore, the structure and the function of only one of the capturing devices 4.1 and 4.2 will be described. In Figs. 3 and 4, several views of the fishing device 4.1 are shown. The embodiment of the catcher is shown in Fig. 3 in a cross-sectional view and in Fig. 4 in a longitudinal sectional view. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The separating device 7.1 has a knife 27, which is preceded by a blocking means 26. The locking means 26 is formed in this embodiment as a mechanical rocker arm 32. The rocker arm 32 may be L-shaped and has a guide arm 34 which extends above the blade 27 substantially parallel to a blade 41 of the blade 27. Orthogonal to the guide arm 34, the rocker arm 32 a holding arm 33 which cooperates with a force transmitter 36 and is held by a holding force in the position shown in Figures 3 and 4. The rocker arm 32 is pivotally mounted on a pivot axis 35. The power transmitter 36 is formed in this case by a permanent magnet 37, on the contact surface of the holding arm 33 is held. The holding arm 33 is made metallic, so that a magnetic holding force on the rocker arm 32 can be generated. The permanent magnet 37 is held by a magnet holder 43 in the separator 7.1.

The knife 27 is disposed below the rocker arm 32 and held by a knife carrier 38. The rocker arm 32 and the knife 27 are associated with two opposing guide plates 30.1 and 30.2, each having a guide groove 31. The guide groove 31 extends to the knife 27, wherein a groove bottom of the guide groove 31 is below the cutting edge 41 of the knife 27. Above the groove bottom of the guide groove 31, the guide arm 34 of the rocker arm 32 extends substantially parallel to the groove base and penetrates a guide plane spanned by the respective guide groove 31 in the guide plates 30.1 and 30.2. In operation, the fiber strand is automatically inserted into the guide groove 31 during the yarn transfer and guided on the surface of the guide arm 34 from the rocker arm 32. This process is achieved by rotating the winding turret 2 and positioning the traversing yarn guide 9.

In Fig. 5 this situation is shown. After the winding turret 2 has carried out the change of the winding spindles 3.1 and 3.2 and the positioning of the fiber strand by the traversing yarn guide 9 has taken place, the transfer begins. The incoming fiber strand, which is identified by the reference numeral 42, is guided over the roller pairs 15.1 and 15.2 laterally next to the winding tube 5.2 of the winding spindle 3.2. By rotation of the winding turret 2 while the support rod 22.1 and the guide rod 23.1 are guided in the yarn path of the fiber strand. When starting the winding turret 2, the traversing yarn guide 9 is first held in a central coil area. Subsequently, the traversing yarn guide 9 is guided in the lateral change position next to the winding tube (as shown in FIG. 1), the fiber strand being automatically guided into the guide groove 31 of the separating device 7.1 (as shown in FIG. 3). The fiber strand falls into the catching groove 39 of the winding spindle 3.2 and is detected by a fishing hook 40. Until this time, the fiber strand is still wound by the full bobbin 6 on the winding spindle 3.1. As soon as the fiber strand 42 on the winding spindle 3.2 is fixed by the catching device 4.1 and the winding tube 5.2, a thread tensile force is generated on the thread piece between the full bobbin 6 and the winding spindle 3.2. In order to prevent unintentional removal of the full bobbin, the winding spindle 3.1 is braked, so that the increase in the yarn tension in the fiber strand 42 causes the rocker arm 32 is pivoted and the guide groove 31 for immersing the fiber strand releases, so that the fiber strand in the cutting edge 41 of the knife 27 is cut.

As is apparent from the illustrations in Fig. 3 and 4, the rocker arm 32 remains in its locked function as long as the holding force on the holding arm 33, in this case by the permanent magnet 37 as Magnetic holding force is generated, is greater than the actuation force on the guide arm 34. Here lever lengths and attack points are taken into account, so that the absolute values of the forces can be different. The actuating force acting on the guide arm 34 is determined by the yarn tension of the fiber strand 42 which is guided on the surface of the guide arm 34. By acting on the holding arm 33 holding force can thus be determined a minimum tensile force of the fiber strand, through which a pivoting of the rocker arm 32 takes place. As soon as the rocker arm 32 flips away, the fiber strand 42 reaches the cutting edge 41 of the knife 27 and is severed immediately. Subsequently, the rocker arm 32 can be guided back into a starting position by the permanent magnet, which has an attractive effect on the holding arm 33. When transferring the fiber strand, it can be fixed to both the winding spindle and the winding tube by clamping or by winding. It is essential here that a severing of the fiber strand only takes place after a minimum tensile stress has been built up in the yarn section of the fiber strand between the full bobbin 6 and the take-up spindle 3.2 to be taken over.

The procedure described above for transferring the fiber strand takes place in an identical manner during the transfer of the fiber strand from the winding spindle 3.2 to the winding spindle 3.1. The winding device according to the invention is therefore particularly suitable for enabling reliable yarn transfers at relatively low winding speeds and low process speeds. Premature or irregular separations of the respective winding material are excluded by the construction of a minimum tensile stress.

The embodiment of the winding device according to the invention according to FIGS. 1 and 2 is exemplary. Thus, the drive of the traversing device can also be achieved by a linear motor or a driven sweeper. Carry out a thread shaft. Depending on the Spulgut the traversing yarn guide could also be formed by a yarn guide element or a pair of rollers.
