Definitions
- the invention relates to a bobbin winding machine having a plurality of winding stations according to the precharacterizing clause of Claim 1.
- a traversing device which has a flyer traversing unit for each winding station.
- Flyer traversing units of this type are suitable, in particular, for being able to guide the respective thread to and fro in the winding station at high speeds.
- the flyer traversing units have two contradirectionally rotating flyer rotors which guide the thread alternately to and fro.
- the flyer traversing units are driven synchronously, the torque of an electric motor being transmitted via a belt drive to each of the flyer traversing units.
- the toothed belt has two opposite profile sides, on which a toothing having a multiplicity of projecting belt teeth is formed.
- the toothed belt is guided within the belt drive via at least one driving wheel and a plurality of drive wheels, the driving wheel and drive wheels being in engagement with the opposite profile sides of the toothed belt.
- the starting load and braking load generated via the driving wheel are absorbed by the opposite profile side which is usually designed to be more wear-resistant.
- alternating meshing on the toothed belt causes vibrations to occur on the toothed belt, this, as what is known as the polygon effect, adversely influencing the uniformity of traversing in the winding stations.
- the polygon effect is additionally promoted also by the unequal manufacturing tolerances of the profile sides.
- the object of the invention is to provide a bobbin winding machine of the generic type, in which the flyer traversing units can be driven with high uniformity in the winding stations.
- toothed belt is coupled to the toothed drive wheels and to the toothed driving wheel via a toothed profile side.
- the joint engagement of the driving wheel with the drive wheels on one toothed profile side of the toothed belt does not have an adverse effect upon the positioning accuracy for driving the flyer rotors.
- the wear phenomena generated by the driving wheel on the toothed profile side of the toothed belt can be limited in such a way that, even if there was a plurality of drive wheels, no phase differences arise between the driven flyer rotors of the flyer traversing units. If all toothed wheels contact the toothed belt on one side only, the other side of the toothed belt may be toothed as well or flat.
- Belt guidance between the drive wheels and the driving wheel can be improved further in that the deflecting rollers have in each case a guide casing with one or more continuous guide grooves, and in that the toothed belt can be guided on the flat side by the guide casing with or without an endless longitudinal web. Transverse guidance of the toothed belt is thereby generated and prevents the toothed belt from moving up and down. In particular, what is achieved thereby is that the belt teeth can roll on the drive wheels under identical geometric conditions.
- these are preferably arranged together with the drive wheels and the driving wheel on a plate-shaped carrier which is held movably on a machine stand.
- a traversing distance formed between the flyer rotors and a following contact roller can be kept constant even with growing bobbin diameters and with a movable pressure roller.
- a plurality of damping elements are provided between the traversing carrier and the machine stand, so that the vibrations generated by the drive of the bobbin winding spindles and the winding of the bobbins are not transmitted to the drive system of the traversing device.
- each of the flyer traversing units has a power divider which is coupled to the drive wheel and which drives two rotatable flyer rotors contradirectionally.
- adjacent flyer rotors can be driven codirectionally or contradirectionally.
- the bobbin winding machine is preferably designed in such a way that the power dividers are formed alternately by one of two types of gear which generate an opposite direction of rotation on the flyer rotors.
- the generation of noise can be influenced positively by the development of the invention in which the flat side of the toothed belt carries a damping textile ply, the basic material of the toothed belt being formed from a polyurethane, and a plurality of steel cords being embedded in the basic material.

- Figs 1 and 2 illustrate an exemplary embodiment of the bobbin winding machine according to the invention in various views.
- Fig. 1 shows diagrammatically a front view
- Fig. 2 diagrammatically a top view of the exemplary embodiment.
- the illustrated exemplary embodiment of the bobbin winding machine according to the invention is conventionally used in a production process for synthetic threads in a melt-spinning plant for winding a group of threads which are extruded, drafted and treated as a thread group and are delivered to the bobbin winding machine.
- the bobbin winding machine one of a plurality of winding stations is formed for each of the threads.
- the exemplary embodiment has altogether four winding stations 5.1 , 5.2, 5.3 and 5.4 in order in each of the winding stations 5.1 to 5.4 to wind a thread into in each case a bobbin 6.1 to 6.4.
- the bobbins 6.1 to 6.4 are held next to one another on a projecting bobbin winding spindle 2.
- the bobbin winding spindle 2 is driven in such a way that the threads are wound on the bobbins 6.1 to 6.4 at an essentially constant winding speed.
- the bobbin winding spindle 2 is preceded by a traversing device 7.
- the traversing device 7 has for each of the winding stations 5.1 to 5.4 in each case a flyer traversing unit 8.1 to 8.4.
- the flyer traversing units 8.1 to 8.4 are driven as a drive group by an electric motor 10.
- the deflecting roller 16.1 is arranged between the drive wheels 11.1 and 11.2, the deflecting roller 16.2 between the drive wheels 11.2 and 11.3 and the deflecting roller 16.3 between the drive wheels 11.3 and 11.4.
- the deflecting rollers 16.1, 16.2 and 16.3 are assigned to a flat side of the toothed belt 12.
- the toothed belt 12 can be guided with alternating looping between the drive wheels 11.1 to 11.4 and the deflecting rollers 16.1 to 16.3.
- the return of the toothed belt 9 takes place via two guide wheels 15.1 and 15.2 which have a toothing and which cooperate with the profile side of the toothed belt 12.
- each of the flyer traversing units 8.1 to 8.4 has a power divider 13 which is coupled directly to one of the drive wheels 11.1 to 11.4.
- the winding station 5.4 having the flyer traversing unit 8.4 is shown diagrammatic ally in Fig. 1.
- Each of the flying units 8.1 to 8.4 and each of the following winding stations 5.1 to 5.4 are constructed identically, and therefore the winding station 5.4 having the flyer traversing unit 8.4 is explained by way of example by means of the illustration in Fig. 1.
- a first flyer rotor 17.1 having a first flyer set and a second flyer rotor 17.2 having a second flyer set are driven contradirectionally by the power divider 13.
- the flyers of the flyer rotors 17.1 and 17.2 are assigned a guide ruler 26, at which guide edge a thread 31 can be guided to and fro via the two flyer sets.
- the flyer sets of the flyer rotors 17.1 and 17.2 are designed in such a way that adjacent flyer rotors of adjacent flyer traversing devices 8.1 and 8.2 mesh with one another.
- the power divider 13 is preferably formed by two types of gear which generate an opposite direction of rotation on the rotor flyers.
- the power divider 13 can be designed as a left-handed gear or right-handed gear.
- the flyer traversing unit 8.4 is arranged on a plate-shaped traversing carrier 21 which extends over the entire traversing apparatus 7 and carries the belt drive 9 and also the other flyer traversing units 8.1 to 8.3.
- the traversing carrier 21 is supported on pivoting arms 19 which are held pivotably in a machine stand 1 via a plurality of damping elements 32 and which carry a pressure roller 18 at their free ends.
- the pressure roller 18 is mounted rotatably on the pivoting arms 19 and bears against the surface of the bobbins 6.1 to 6.4 during the winding operation.
- the traversing carrier 21 is held next to the pressure roller 18 by the pivoting arm 19, so that the traversing carrier 21 is guided movably, together with the pivoting arm 19, on the machine stand 1.
- a traversing distance formed between the guide rulers 26 and the pressure roller 18 is consequently kept constant independently of the respective position of the pivoting arm 19.
- the threads can be guided to and fro with identical drag lengths by the flyer traversing units 8.1 to 8.4.
- a spindle carrier 4 in the machine stand 1 is designed as a bobbin winding turret, on which a second bobbin winding spindle 3 is held in a projecting manner.
- Each of the bobbin winding spindles 2 and 3 can be driven independently of one another, the spindle carrier 4 likewise being assigned a drive. In this exemplary embodiment, the drives are not illustrated.
- the bobbin winding spindle 2 is guided by the movement of the spindle carrier 4.
- the threads When the threads are being wound into the bobbins 6.1 to 6.4, they are guided to and fro at a stipulated traversing frequency by the flyer traversing units 8.1 to 8.4.
- the traversing frequency of the flyer traversing units 8.1 to 8.4 is determined by the electric motor 10 and is transferred from the driving wheel 14 to the drive wheels 11.1 to 11.4 via the toothed belt 12.
- These changes are likewise carried out directly via the electric motor 10 and the belt drive 9. High dynamic loads thus occur on the toothed belt 12 and are accompanied by speed changes.
- Fig. 3 illustrates an exemplary embodiment of a deflecting roller 16.1 diagrammatically in a cross-sectional view.
- the deflecting roller 16.1 has a guide casing 28 which is mounted rotatably on a shaft 33.
- the guide casing 28 has on the circumference a guide groove 29 which receives a flat side 23 of the toothed belt 12.
- the toothed belt has a profile side 27 having the belt teeth 22.
- Fig. 4 shows a deflecting roller 16.1 diagrammatically in a cross section.
- the guide casing 28 has two guide grooves 29 running parallel.
- the guide grooves 29 are designed in such a way that two longitudinal webs 30 on the flat side 23 of the toothed belt 12 can be guided therein. Reliable and quiet running of the toothed belt 12 is consequently achieved particularly in the region of the drive wheels 11.1 to 11.4.
- Fig. 5 illustrates a partial view of the toothed belt 12
- Fig. 6 a cross- sectional view of the toothed belt 12.
- the toothed belt 12 has a profile side 27 and an opposite flat side 23.
- a multiplicity of belt teeth 22 are formed on the profile side 27.
- the toothed belt 12 is designed as an endless belt.
- the belt teeth 22 integrally formed on the profile side have in each case the form of a parabola with completely filled tooth tips.
- the parabolic form of the belt teeth 22 is essentially identical to the known high-performance profiles bearing the designation RPP.
- the spacing T is set at a value in the range of between 4 mm and 5 mm.
- the fly traversing units 8.1 to 8.4 of the traversing device 7 can consequently be driven reliably and free of slip.
- the introduction of a torque, via the driving wheel 14 and the transmission of the torque to the drive wheels 11.1 to 11.4 can advantageously be carried out via the profile side 27 of the toothed belt 12.
- the loads generated by the driving wheel 14 during the starting, changing and braking of the traversing frequency do not have an adverse effect upon the positioning accuracy of the phase positions of the flyer traversing units.
- High uniformity in the winding of the threads in each of the winding stations 5.1 to 5.4 can consequently be achieved.
