    Description: [0001] The invention relates to a stranding machine according to claim 1 and to a method according to claim 11.
    Conventionally known stranding machines cause minor stranding errors due to a phase shift between an unwinding bail and a wind-up bail. The driven feed bobbins are translated 1: 1 to the stranding bracket, thus have the same speed due to a coupling via a drive. The unwinding is for unwinding of the product to be stranded, hereinafter referred to strand, braked by the bobbin and the unwound by the unwinding from the bobbin length of the strand depends on the degree of filling of the delivery bobbin. The take-up is associated with a take-up drum for the stranded finished product, hereinafter referred to as cable, wherein here the take-up is braked relative to the take-up drum, which has a corresponding phase shift result. Since the Abwickelbügel is braked against the coupled with the Verseilbügel drain reel, the rotational movement of the Abwickelbügels against the rotational movement of the Aufwickelbügels with a, shifted by the different rotational speeds, dynamically changing phase, resulting in a twist of stranded strand results, which in turn lead unwanted tension in the cable. This strain is to be compensated by a targeted twisting of the cable, but this does not lead to the desired success, since the changing degree of filling the drain coil affects the unwound length of the strand and corresponding differences of the stranded individual strands can not be compensated by a twist of the cable , The production-related stranding faults and prestressing in the strands to be stranded can lead to premature failure in the case of highly dynamic loading, for example when used in robots or drag chains.
    The invention has for its object to provide a stranding machine of the type mentioned, which avoids the above-mentioned disadvantages in a variable use.
    The dependent claims represent advantageous embodiments of the invention.
    A stranding machine comprises a plurality of most settled unwinding units, each having at least one delivery reel for a product to be stranded, which is associated with a driven unwinding hanger, and a take-up reel for the finished product, which is associated with a driven rewinding hanger.
    The speed of Abwickelbügels for a centrally extending product is synchronized to the speed of the take-up.
    In the context of the invention, the term product any strandable material, so for example a plastic thread, a wire or cable strand, and the term finished product, the corresponding stranded material, so for example a plastic or wire rope or a multi-core cable called ,
    Characterized in that the speed of Abwickelbügels for the centrally extending product, so to speak, the neutral fiber is synchronized to the speed of Aufwickelbügels of the finished product, distortions of the stranded product and resulting Verseilungsfehler are excluded. The finished product has a prolonged life, especially at a relatively high dynamic load.
    In a stranding machine in an alternative embodiment of the unwinding U-shaped design and includes bearings and drive components for the delivery reel, wherein the delivery reel is assigned to the unwinding that a radial or tangential unwinding of the product to be stranded by the appropriately aligned delivery bobbin ,
    Accordingly, it is not necessary to provide two different stranding machines according to the prior art in order to use the different results of the radial or tangential development of the product to be stranded. Rather, after a relatively simple conversion of the multifunctional stranding one or the other unwinding to realize.
    Preferably, the delivery bobbin for radial development of the product is stored such that the circumference of the delivery bobbin runs parallel to the two legs of the unwinding and the front sides are assigned bearings, wherein a web of Abwickelbügels associated end side of the delivery bobbin is connected to the drive and the product withdrawn passes over a pulley associated with the unwinding bail. Of course, it is possible to provide an additional bearing point by means of a flange between the legs of Abwickelbügels at the opposite side of the legs connecting the legs, so in the region of the free ends of the legs, in particular to lead a relatively heavy drainage coil reliable. Conveniently, the end face of the delivery bobbin is coupled directly to the drive via a detachable toothing.
    Alternatively preferably, the delivery bobbin for tangential handling of the product is stored such that the circumference of the delivery bobbin runs parallel to the web of Abwickelbügels and the two legs of Abwickelbügels are associated with the end faces of the bobbin cooperating bearings, one end of the bobbin with connected to the drive. The drive is coupled via an angle drive indirectly, in particular with the interposition of a drive belt, with the drainage coil. The angle drive may for example comprise two bevel gears.
    The Abwickelbügel may include all components that are needed for a radial or tangential settlement, and the delivery reel is easily pluggable connected to the drive and / or bearing elements. Preferably, the delivery bobbin is interchangeably arranged in the unwinding bar.
    Conveniently, the take-up reel for the finished product and the take-up on different speeds and the take-up reel is translationally displaceable. The speed of rotation of the take-up spool is also controlled in dependence on the degree of filling, which results in a changing winding diameter and a corresponding peripheral speed.
    The take-up reel is associated with a rolling ring gear which reciprocates between end-stops set to the mutual distance of the end faces of the take-up reel with a pitch set to the diameter of the finished product. Due to the displacement of the take-up spool, it is not necessary to take into account an angle of the finished product from the take-up reel to the take-up reel, which has an influence on the translation speed of the finished product, and the speed of the drive shaft on which the take-up reel is arranged is relatively easy to control ,
    In order to adjust the required for unwinding and winding differences in the speeds and a target speed is in a design between a drive shaft and the delivery reel and the associated Abwickelbügel each a continuously variable transmission and between the drive shaft and the take-up reel as well the associated take-up also arranged in each case a continuously variable transmission.
    Preferably, measuring devices for the translation speeds of the individual products to be stranded and / or the finished product are arranged. On the basis of the data of the measuring devices, the other speeds can be regulated, for example by means of PID controller.
    In a method for stranding a product, resp. For controlling the speeds of the delivery bobbins and the associated unwinding hanger, first the rotational speeds of the delivery bobbins and the unwinding bail are synchronized so that no product is unwound, then a gear ratio is changed such that a product running in the center of the assembly reaches a predetermined target speed achieved, which is measured with an associated measuring device, and the translation speeds of the other products to be stranded products are increased in contrast.
    It is understood that the above-mentioned and below to be explained features not only in the particular combination, but also in other combinations can be used. The scope of the invention is defined only by the claims.
    The invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. It shows:

    The stranding machine comprises a plurality of most settled unwinding units 1, which are each composed of at least one delivery reel 2 and a delivery reel 3 which stores the delivery reel 2. Products 4, for example strands 5, which are unwound from the delivery bobbins 2 are guided through a perforated disc 6 to a take-up unit 7 which comprises a take-up reel 8 and a take-up reel 9, wherein the finished product 10, for example a cable 11, is wound on the take-up reel 8 , All unwinding units 1 and the winding unit 7 is associated with a drive shaft 12 with pulleys 13.
    Each substantially U-shaped Abwickelbügel 3 comprises a web 14 and two outgoing leg 15 thereof, between which the supply reel 2 can be arranged to unwind in the radial or tangential direction of the strand 5. In order to set the unwinding bar 3 in a rotational movement, a pulley 16 is arranged on the web 14, which is connected via a drive belt 17 to the drive shaft 12. Through the pulley 16, a shaft 18 extends, which is coupled to a belt drive 19 of a continuously variable transmission 20 and the other to the unwinding spool 2. The transmission 20 is connected via a belt drive 50 with the drive shaft 12 in connection.
    If the stranded wire 5 are unwound radially from the delivery bobbin 2, then the delivery bobbin 2 is mounted in the unwinding bail 3, that has a front side 21 in the direction of the web 14 of the unwinding bar 3 and runs substantially parallel to this and the other end face 22 is mounted on a fixed between the legs 15 of the unwinding 3 flange member 23. The drive shaft 12 is coupled within the Abwickelbügels 3 by means of a plug connection 24, which includes, for example, a toothing, with the delivery spool 2. The connector 24 is arranged between two parallel and spaced apart from the web 14 and mutually arranged flanges 29, wherein the one flange is associated with a storage 25 for the delivery reel 2. The strand 5 is guided by the delivery reel 2 via a deflection roller 26 assigned to a leg 15, by a contactor 27 in the flange component 23 and by a measuring device 28 for detecting the translation speed and subsequently through the perforated disc 6 to the reeling unit 7.
    If it is desired to unwind the strand 5 tangentially from the delivery bobbin 2, then the delivery bobbin 2 is mounted in the unwinding bail 3, that the end faces 21,22 are aligned parallel to the legs 15 of the unwinding bail 3, wherein the one end face 21 a console 30 with a bearing 31 and a drive element 32 and the other end face 22 a bearing 33 is associated with a spacer 34. The connected to the gear 20 shaft 18 drives a gear transmission 35 which is arranged in the region of the web 14 and the two flanges 29, wherein the angle gear 36 comprehensive gear transmission 35 via a belt drive 37 in the region of the console 30 with the drive element 32nd is coupled. The tangentially unwound from the flow bobbin 2 strand 5 is guided via the measuring device 28 and the perforated disc 6 to the winding unit 7 and wound there as a finished cable 11.
    In the winding unit 7, the cable 11 passes through a measuring device 38 and passes from this through a hollow shaft 39 of the substantially rectangular Aufwickelbügels 9 via legs 40 of the Aufwickelbügels 9 mounted rollers 41 to the take-up reel 8. The hollow shaft 39 carries a pulley 42nd and is connected to rotate the Aufwickelbügels 9 via a belt 43 to the drive shaft 12 which drives via a further belt drive 44 coupled to the take-up reel 8 continuously variable transmission 45. The take-up reel 8 is associated with a chassis 48 reciprocable by means of a motor 46 and an intermediate rolling ring gear 47, a so-called Uhing gear, and is moved under the take-up reel 9 such that the cable 11 is wound in adjacent turns. In order to ensure a rotary drive of the take-up reel 8 in a simultaneous translational movement, the gear 44 is connected to the take-up reel 8 with the interposition of a ball spline 49.
    The translation speed of the central strand 5 is used as a reference for the further considerations with respect to the control of the stranding machine and kept constant as a reference variable.
    When starting the Verseilungsmaschine the ratio is set to 1: 1 at all continuously variable transmissions 20 of the unwinding units 1 until the working speed of the drive shaft 12 is reached. In this case, no strand 5 is unwound from the delivery bobbins 2. Subsequently, the translation on all continuously variable transmissions 20 of the unwinding units 1 with a corresponding conservative control so as not to tear off the strands 5, e.g. by a tuned PID controller, slowly changed until a predetermined target speed of the central strand 5 is reached. The other strands 5 must be unwound necessarily with a greater translation speed to compensate for the difference in length to the middle strand 5 due to the stranding, for example in the form of a spiral. For this purpose, a correspondingly faster change of the translation at the same degree of filling of the delivery bobbins 2 is required. The following applies:
    When winding the target translational speed of the middle strand 5 is used as a reference, as this is crucial for the cable 11.
    The displacement speed of the chassis 48 by means of the rolling ring gear 47 results from the speed difference between the winding yoke 3 and the take-up reel 8 and the width or the diameter of the cable eleventh
    Ti rotation is in the above formula, the time in which the take-up bracket 9 has performed a revolution more than the take-up reel. 8
    Since the speed of the take-up reel 8 also changes at a constant speed of translation of the cable 11 due to the changing degree of filling and the concomitant change in the radius, the speed of the driving motor 46 must be regulated accordingly. That is, as the filling state increases, the rotational speed of the take-up reel 8, and hence the shifting speed, decreases due to the circumference when the translation speed of the cable 11 is constant. Consequently, when the rolling ring gear 47 is set at a constant value, the driving speed of the motor 46 must be lowered.
