Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a winding machine for yarn, in which a traversing device for reciprocating the yarn over a traversing stroke is configured as a vane-shaped zigzag device, and the yarns are arranged in close proximity to each other. The two arm-shaped blades are eccentrically supported and rotate in opposite directions in the rotating plane, the guide bar on which the thread guide edges of the blades rub against each other, and the lower A guide roller located just below the rotating plane is provided, and the thread is partially wound around the guide roller and guided to the bobbin.

This winder is particularly suitable for yarns, especially synthetic yarns, which are continuously run in and wound up at speeds higher than 6000 m/min.

The winding machine known from German Patent No. 1560469 = British Patent No. 1168893 has two biarm-like blades which are eccentrically supported relative to each other as a traversing device. . The advancing arms of both vanes are offset by 180 with respect to each other, and the vanes rotate in opposite directions of rotation. The entraining arm guides the thread via a curved guide bar which serves as a thread support, the configuration of which determines the traversing speed of the thread during the course of the traversing stroke. The thread is then guided through a guide roller around which the thread is partially wound. This guide roller is rubbed at small distances by a driving arm.

The object of the invention is to improve a winding machine of the type mentioned at the outset and to provide a winding machine suitable for winding a plurality of threads. In this case, it is particularly desirable for several yarns entering from the same direction to be wound onto individual winding spindles in several winding ranges that are arranged close to one another in a row.

In order to solve this problem, in the configuration of the present invention,
A plurality of traversing devices are arranged side by side with each other in order to reciprocate each thread over the traversing stroke and wind the plurality of threads onto a plurality of coaxially arranged bobbins. The blades of the oscillating devices are arranged in two planes of rotation closely adjacent to each other, the guide rollers of all traversing devices are arranged coaxially, and the planes of rotation of the blades of adjacent oscillating devices overlap each other. The blades of adjacent traversing devices arranged in the same plane of rotation have the same distance between the axes between the traversing devices, and the distance between the axes is equal to the distance between the axes of the blades. The blade radius is smaller than twice the radius but larger than the blade radius x √2, and blades of adjacent twirling devices placed on the same plane of rotation are driven in the same direction with a phase shift of approximately 90°. has been done.

With this configuration, mutually adjacent zigzag devices can be arranged very close to each other. In this case, although it is possible to arrange the winding tubes that are fastened to the winding spindle in close proximity to each other or to abut each other on their end faces, there is no possibility of waste winding and/or yarn prewinding. The space necessary to form a spool can be left in each tube.

Due to the fact that all the blades of all traversing devices are distributed over only two planes of rotation, it is possible to arrange the blades with a small distance between them.
Furthermore, by arranging all the guide rollers coaxially, an even yarn running relationship is guaranteed between one zigzag device and another zigzag device,
This results in bobbins having equal winding characteristics. Furthermore, as in the present invention, when the guide rollers are disposed coaxially with each other under the rotating plane of the lower side of the blades and in close proximity, the generatrix of the bobbin on which the thread is wound is parallel to and parallel to the guide rollers. If the bobbin is located at a very small distance from the guide roller or is in contact with the guide roller at its outer periphery, the bobbin can be freely supported and arranged. Under these prerequisites, it is possible to produce cylindrical or conical bobbins or to produce bobbins with different beginnings, lengths, or ends of the winding time.

Advantageously, the vane has, on the side opposite the pushing edge, a guiding edge, referred to herein as a "braking tongue", which guide edge forms a connection between the guide bar and the guiding edge. The intersection is shaped so that it moves toward the center of the zigzag stroke at approximately zigzag speed.
With this configuration, it is avoided that the yarn moves toward the center of the traverse stroke faster than the speed of the pushing edge of the blade toward the center of the traverse stroke.

At the beginning and end of the winding process, it is necessary to remove the thread from the traversing device. For this purpose, according to a further embodiment of the invention, the guide bar is located on the side of the thread running plane, on which side the transmission of the rotor is also arranged, and the guide bar is located on the driving arm. The guide bar can be moved away from the rotor axis until it is no longer covered.

In a further advantageous embodiment of the invention, the guide bar has a thread gripping cutout (thread guide cutout) on the outside of the swivel stroke. When the guide bar is removed from the area covered by the blades of the traversing device, the thread slips into this thread gripping notch. In this case, it is advantageous if the thread gripping recesses are arranged on both sides of the twisting stroke.

With this configuration, the guide bar can, for example, direct the running yarn to the yarn reserve area of the winding tube and/or
It can act as a thread guide mechanism for guiding to the gripping area. For this purpose, the guide bar may be movable relative to itself and/or parallel to the rotor axis.

By suitably configuring the shape of the guide bar, defined laws of motion for the thread can be realized. For example, the thread traversing speed can be reduced in the central region of the traversing stroke, which makes it possible to wind the thread approximately 2% higher in the central region than in the end regions.

By arranging the guide bar on the side of the thread path on which the rotor transmission is located, the blades can additionally be protected by a protective strip on the thread running side (thread handling side). This protective strip extends beyond the plane of rotation of the vanes in the thread running direction. This protective strip is fixed in an overhanging manner at one end of the traversing stroke range and extends parallel to each traversing stroke. At the other end of this traversing range, the protective strip forms a slit-like threading opening which extends towards the thread running plane. With this construction, on the one hand, it is possible to prevent the blades from being damaged by the rotating blades, and on the other hand, it is also possible to prevent the blades from being damaged by the suction piston, which acts as a thread guide during thread operation, for example when inserting the thread. Avoided.

It is advantageous if the slit-like threading opening opens into a thread preparatory device, which is known per se, in which case the thread preparatory device grasps the thread and, after several windings, brings it into the region of the twiddling stroke, and in this region released, where the thread is captured by the feathers.

In a further embodiment of the invention, the guide bar is configured as a forced guide in at least one area, and in this area of the forced guide the guide bar has front and rear guide rails.
With this configuration, lifting of the thread from the guide rail can be avoided. This is particularly advantageous at the end of the traverse stroke if it is desired to wind the thread with a winding law that is significantly accelerated or retarded at the end of the traverse stroke.

It is also possible to give different courses to the two guide rails of the guide bar and to configure the guide edges of the vanes in such a way that they guide the yarn along different guide rails on the outward journey than on the return journey. It is possible. It is well known that it is desirable to shorten the so-called slip length that occurs between the pushing edge of the blade and the point where the thread runs onto the bobbin. , can be significantly reduced by arranging guide rollers at a small distance which are rubbed by the thrust edges of the vanes. This guide roller advantageously has a relatively small diameter, so that the point of entry of the thread onto the guide roller is located directly below the lower plane of rotation. This spacing is approximately equal to the radius of the guide roller. In order to reduce the slip length, the traversing device is preferably arranged such that the plane of rotation of the vanes is not perpendicular to the plane of thread travel, but rather lies in the plane of travel of the thread in the region of the thread entering the plane of rotation. It is tilted at an extremely small angle of 45° to 70°. With this configuration, the slip length between the plane of rotation of the blade and the point at which the yarn rides onto the guide roller can be made even smaller than the radius of the guide roller.

At the same time, if the rotor transmission is arranged on the side of the plane of rotation opposite the bobbin, space is available for arranging the drive roller between the plane of rotation and the bobbin. This drive roller is in contact with the bobbin at its outer periphery and is driven at a constant rotation speed.

The thread is guided from the guide roller to the bobbin almost without slipping. In order to completely avoid slippage between the guide roller and the bobbin, the guide roller may be in contact with the outer peripheral surface of the bobbin. In this way, the guide roller simultaneously serves to increase the distance between the winding spindle wire axis and the traversing device as the bobbin diameter increases. In this case, the guide roller is preferably spring-suspended, so that it can be deflected if the bobbin is non-circular. In addition to this, the spring-elastic suspension of the guide roller makes it possible to use the drive roller at the same time. If the guide roller is suspended elastically, the drive roller or guide roller is prevented from lifting off the outer circumferential surface of the bobbin as the bobbin diameter increases during the winding process. For this purpose, the drive roller and the guide roller as well as the traversing device are both mounted on a carriage, the guide roller being elastically movable relative to the carriage. The drive of the carriage may be controlled in conjunction with a spring-elastic deflection of the drive roller.

The transmission device and the rotor drive device are in a rotating plane,
If it is located on the side of the winding spindle, that is to say behind the plane of rotation of the blades in the thread running direction, the traversing device is easier to maintain, especially when the bobbin is remote. Such an arrangement eliminates the need to remove the rotor transmission if the bobbin is formed on the rotor.

In embodiments in which the transmissions of all rotors are located on one side of the plane of rotation, one of the rotors has a hollow shaft that is rotatably mounted. A shaft on which the other rotor is mounted is eccentrically supported on this hollow shaft. In this case, the hollow shaft and the shaft may be driven separately from each other, for example by belts or gear wheels. However, in the traversing device of the winding machine according to the invention, the two rotors are moved very precisely relative to each other in the range of the traversing stroke in order to ensure a precise thread transfer from one blade to the other at the end of the traversing stroke. Since the adjustment is important, in a preferred embodiment of the invention the hollow shaft and the shaft are in particular electrically connected to one another by a transmission shaft which is mounted inside the hollow shaft. The transmission shaft is such that the hollow shaft and the shaft rotate at the same rotational speed but in opposite rotational directions and in precise relative positions.

With the above-mentioned embodiment, it is also possible for each traverse stroke range to form a housing as a structural unit, in which both rotors of this traverse travel range are supported. This casing can be installed and removed for maintenance and repairs independently of the rest of the traversing range.
Adjustment of the precise relative position of the rotors can be made at the manufacturing plant during final assembly. In this embodiment, only one shaft, preferably the hollow shaft, is driven externally. For the drive, belt drives, gear drives, worm gear drives or the like can be used in this case as well.

A preferred transmission connection of the rotors has a common worm axis for the rotors belonging to each plane of rotation.

In another embodiment, the rotors located in the same plane of rotation are all driven by a common tangential belt.

Also, the rotors located in the same rotation plane are
It may also be driven via a bevel gear by a common drive shaft extending over the entire traverse travel range.

In the drive types described above, the rotors located in the other plane of rotation are each likewise driven by one of the drive types, or the rotation for the rotor belonging to one traverse travel range is controlled. the first rotor through the intermediate gears in such a way that they are equal in number but opposite in the direction of rotation and in such a way that the relative position required for accurate yarn delivery at the end of the traversing stroke is guaranteed. It is driven by

In a further embodiment, the transmission of the rotor, whose blades are located in the upper rotational plane viewed in the yarn running direction, has blades located above the blades and rotating in the lower rotational plane. A rotor transmission is located below the plane of rotation. In this case, the housing is preferably split in such a way that the upper housing part can be separated from the lower housing part, for example by pivoting away. This is also advantageous for removing the bobbin and for other cleaning purposes.

Next, embodiments of the present invention will be described with reference to the drawings.

The structure of the winder is shown schematically in FIGS. 2 and 3. In this case, several winding tubes 15 are inserted into the winding spindle 14 one after the other in the axial direction. The winding spindle 14 is driven to rotate in the direction of the arrow 31, so that a plurality of threads 4 are wound onto a corresponding number of bobbins 13. Before each thread 4 passes through the traverse device 1, 2, 3, the thread 4 is moved to the bobbin 13 by the traverse device 1, 2, 3.
The yarn is criss-crossed over the length of the yarn and perpendicular to the yarn running direction. The construction of the sway device, which differs in certain respects in the embodiment shown in FIG. 2 from the embodiment shown in FIG. 3, will be discussed later.
Behind the traversing device, each thread is moved by a guide roller 12
It is guided via the guide roller so as to wrap around the guide roller. As can be seen from FIG. 1, the guide rollers 12 of the plurality of shifting devices 1, 2, and 3 are arranged coaxially with each other in a line.

Each traversing device 1, 2, 3 consists of a vane 5, 6 arranged in a plane of rotation, as shown in FIG. In Figure 1, the blades on the rotating plane are numbered 5 and the blades on the rotating plane are numbered 6.
It is shown in The blades 5 of the traversing device 1, 2, 3, which are arranged in the plane of rotation, are correspondingly designated by 5.1, 5.2, 5.3, and likewise the blades in the plane of rotation of the traversing device. 1, 2, 3
It is indicated by the symbol corresponding to . As can be seen from the above, the blades 5, 6 of all the traversing devices 1, 2, 3 are arranged in only two rotation planes.

As can be further seen from FIG. 1, all blades 5 rotate about axis 10 in the direction of arrow 7, while blades 6 rotate in the opposite direction about axis 11 (see arrow 8).
Rotate to . In other words, all the swaying devices 1, 2, 3
Vanes arranged in the same plane of rotation have the same direction of rotation. Each swaying device 1,
2, 3, the blades 5, 6 are connected to their respective shafts 10,
11 (see symbol e). Axis 10 of each traversing device 1, 2, 3.
1, 10.2, and 10.3 are equal to each other. Similarly, axes 11.1, 11.2,
The same can be said about the center distance of 11.3.

As can be seen from FIG. 1, the rotation circles of the blades 5, 6 of adjacent traversing devices 1, 2, 3, which are arranged in the same rotation plane, overlap with each other. The distance between the axes is chosen to be smaller than the diameter of the blade, but larger than √2×blade radius. In this case, the interval 13 between the winding ranges H1, H2, and H3
can be made extremely small. As a result, for the first time, the traversing devices 1, 2, which are lined up in a row,
3 makes it possible to wind a plurality of bobbins 13. In this case, these bobbins 13 are preferably tensioned and driven on just one winding spindle 14, as shown in the illustrated embodiment.

Other main components of the traversing device include the guide bars 9.1, 9.2, 9.3.
As can be seen in FIG. 2, the guide bar 9 may be located on the same side as the traversing device, or it may be located on the other side, as indicated by the dashed line. However, an arrangement is also possible in which there is one guide rail 29, 30 in each case before and after the thread 4. In such an embodiment, the guide rail acts as a forced guide for the thread. This forced guidance can extend over the entire traverse travel range, but it can also be limited to a partial range, as shown in FIG.

In the embodiment of FIG. 3, the guide bar 9 is located on the same side as the traversing device. In this case, the guide bar 9 can be moved away from the blade axis (arrow 32
reference).

As can be seen from FIG. 3, the two traversing devices shown in FIGS. 2 and 3 are movable up and down on a guide rod 26 and a guide carriage 27. With this arrangement, the traversing device can be deflected as the bobbin diameter increases. It is possible to control or adjust this deflection movement (see, for example, German Patent No. 2,532,165=US Pat. No. 4,106,710).

In the embodiment shown in FIG. 2, the shafts 10, 11 of the blades 5, 6
The transmission device 33 for the traversing devices 1, 2,
3 and the bobbin 13. The advantages of this arrangement include: This means that the blades, which are only covered by a lid (not shown), can be easily cleaned and maintained, and in particular bobbins and thread waste can be easily removed. The transmission 33 is shown schematically as
It consists of a shaft 11, which is a hollow shaft, to which the blades 6 of the lower rotating plane are attached, and a shaft 10, to which the blades 5 of the upper rotating plane are attached, which is supported by the hollow shaft. Both shafts 10, 11 are driven by worm gears 16, 17 and worms 18, 19. The worm shaft extends over the entire traversing device 1, 2, 3, the drive motor being not shown here.

In the embodiment of FIG. 3, the blade 5 of the upper rotating plane
The transmission for the blades 6 of the lower rotation plane is mounted above the rotation plane, and the transmission for the blade 6 of the lower rotation plane below the same rotation plane. These transmission parts are respectively located in an upper housing part 23 and a lower housing part 24. The two transmission parts are synchronously connected to each other by a belt transmission 20. A toothed belt is preferably used for this purpose. A hinge (not shown) is disposed on the pivot shaft 25, that is, coaxially with the belt pulley 21 and the drive body 22, and the upper casing portion 23 can pivot around this hinge, so that the blades can be rotated. It can be seen that the planes of rotation in which the rotation planes 56 are respectively arranged.
This outward rotation makes maintenance of the vanes easier;
In particular, bobbins and thread waste can be easily removed.

The guide bar 9 shown in FIG. 4 can be used in the winder shown in FIG. The guide bar 9 has thread grip notches 28 at both ends outside the traverse stroke range. The guide bar 9 further has an outer guide rail 29 and an inner guide rail 30. The outer guide rail 29 extends only over a partial width of the traversing stroke, in which region the thread is guided forcibly. This is advantageous for imparting special laws of motion to the thread, such as large accelerations or retardations.

The guide bar 9 is movable in the direction of the arrow 34 so that the inner guide rail 30 moves out of the rotation circle of the vanes 5,6. In this position of the guide bar 9, shown in broken lines, the thread is no longer guided but slides into the thread gripping recesses 28 located laterally in the traversing travel range. In this position the thread can be grabbed and sucked out. However, it is also possible to bring the thread into the thread gripper notch 28 for insertion and then to move the guide bar 9 in particular parallel to itself, with this movement causing the thread to be inserted into a winding. It is wrapped in a tube and/or pre-wound with thread. Since the thread gripping notch 28 is located inside the rotation circle of the blades 5, 6, the return movement of the guide bar 9 causes the traversing device to be put into operation again.

In the embodiment shown in FIG. 5, the guide carriage 27 is
6 relative to the bobbin 13. The traversing device according to the invention is mounted on a guide carriage 27 on the one hand and has a guide roller 12 on the other hand. This guide roller 12 is supported by a pivot arm 51 via a pivot shaft 52 .
The swivel arm 51 is supported by a pressure-loading force generator, such as a disc spring set 53, so that the guide roller 12 springs resiliently against the bobbin 1.
Contact 3.

The relative position of the pivot arm 51 with respect to the guide carriage 27 is detected, for example, by a nozzle/baffle system 54. The output signal of this nozzle/baffle system 54 is sent to a schematically illustrated drive (cylinder/piston unit 55) of the guide carriage 27.

The cylinder-piston unit 55 is pressurized via a throttle 57 by a pressure source 56 . The pressure regulated behind the throttle 57 is related to the gap width in the nozzle-baffle system 54.

Additionally, in the embodiment of FIGS. 2 and 3, guide roller 12 may serve as a drive roller or as a control roller. If the guide roller 12 is used as a control roller, the rotational speed of the guide roller 12 is continuously measured and the measured value is sent to the shaft drive motor for the winder, thereby increasing the bobbin diameter. At times, the peripheral speed of the bobbin 13 is kept constant.

FIG. 6 schematically shows the housing of the traversing device shown in FIG. As can be seen in FIGS. 5 and 6, each traversing stroke area is covered by a protective strip 75 on the front side of the machine.
This protective strip 75 in particular also covers the plane of rotation in the thread running direction. On the one hand, this avoids human contact with the rotating blades, and on the other hand, it prevents damage to the blades and misalignment of the relative positions of the blades if a person enters the rotation range of the blades during thread insertion by the yarn suction piston. is avoided. The protective strip 75 forms a thread guide slot 76 opposite the guide bar 9, which is not shown in FIG. Each protective strip 75 overhangs at one end, while the other end of each protective strip 75 forms a threading opening 77 which is located in the guide groove 79 of the thread preparatory device 78. It's open. Once the thread is inserted into the thread preparatory device 78,
The yarn preparatory device 78 is slowly moved in the direction of the arrow 80 toward the center of the twisting stroke. This creates a reserve turn of thread on the bobbin that is located outside the normal traverse range. The yarn reserve device 78 then advances from the yarn area in the direction of arrow 86. As a result, the now free thread moves to the center of the traversing stroke and is gripped by the blades of the respective traversing device.

The structural unit shown in FIG. 7 has a bowl-shaped casing 65 which is circular or oval or elliptical in plan view, the shafts 10 and 11 being eccentric to each other. It is located. The shaft 10 of the blade 6 is rotatably supported in the casing 65 . The shaft 11 of the blade 5 is supported on the housing cover 67, which is also part of the structural unit. The casing cover 67 and the casing 65 are firmly screwed together during assembly. The shaft 11, which is a hollow shaft, has an internal gear 68.
The internal gear 68 has teeth or rolling surfaces 72 on the outside for engagement with a gear or teeth for engagement with a toothed belt. The ring gear 68 is driven in the illustrated case by a drive belt 73, for which purpose the housing 65 has suitable recesses. The rotary movement of the shaft 11 with the internal gear 68 is transmitted to the shaft 10 via the gear 69 and the transmission shaft 66 and gears 70, 71, which are also rotatably mounted in the casing 65, and thereby the shaft 10. 10 rotates in opposite rotational directions but at the same rotational speed. By adjusting the meshing of the gears during assembly, this structural unit can be pre-adjusted in order to pre-adjust the relative position of the vanes 5, 6 in order to ensure a correct thread delivery at the turning point of the traversing stroke. Can be assembled. In this form, this structural unit can be integrated into the machine frame 74, ie into the traversing device housing. It is then only necessary to adjust the relative positions of the rotors of adjacent traversing devices by adjusting the meshing of the gears on the rolling surfaces 72.

The two embodiments shown in FIGS. 8 and 9 correspond approximately to the embodiment shown in FIG. 5, but in the embodiment shown in FIGS. A drive roller 50 is provided, which is supported on. In order to movably support the drive roller 50 in this case, a bearing 81 is guided in a linear guide in FIG. A nozzle of a nozzle/baffle plate system 54 is fixed to the guide carriage 27, and the relative movement of the support 81 with respect to the guide carriage 27 is detected by this nozzle. This influences the pressure in the holding system (cylinder-piston unit 55), and as the bobbin diameter increases, the distance between the nozzle and the baffle decreases, which in turn increases the pressure in the system, which results in an increase in the pressure on the guide carriage. 27 moves upward until it again creates a pressure balance.

In the embodiment of FIG. 8, the guide roller 12 and the drive roller 50 are supported on a common pivot frame 83, in which case the pivot frame 83 is mounted on a pivot shaft 84.
It is possible to rotate around. The pivot shaft 84 is mounted on a bearing 85 which itself is movable relative to the carriage in a guide and is supported on a disc spring set 82 . In this embodiment as well, the relative movement of the support 85 is controlled by the nozzle and
It is detected by the baffle plate system 54 and applied to the cylinder/piston unit 55.
