Definitions

  • the invention relates to a high-speed stranding machine with at least one bobbin floating within the rotor and prevented from rotating with the rotor due to imbalance.
  • the rotor is driven at high speeds.
  • a wire runs from each coil inside the rotor, which is rotatably mounted in the coil carrier that does not support the rotation of the rotor.
  • the wires from all coils of the machine are led out of the rotor to the stranding point and stranded there by the rotor rotation.
  • the bobbin can be accelerated by a defective bobbin bearing, by a broken wire or by a wire that is clamped between the bobbin and the Roto.
  • the speed that the coil carrier assumes is dependent on the ratio of the moments of inertia of the rotor and the coil carrier with the coil, on the braking time and on the torque that occurs between the rotor and the coil carrier when, for example, a bearing is blocked. If the torque occurring is very high (in the order of 10,000 Nm), the acceleration is so high that the coil carrier assumes approximately the full rotor speed, although the rocker lock responds correctly.
  • the very high loads caused by the centrifugal forces are
  • the object of the invention is to design a high-speed stranding machine in such a way that the bobbin is reliably prevented from rotating on the one hand during operation and, on the other hand, in the event of a fault, the loads that occur are kept within such limits that they can be absorbed by the machine without damage or even destruction of individual parts can.
  • OMPt predetermined torque value in the clutch with the coil carrier can be uncoupled from this.
  • the centrifugal forces which occur are reduced by the invention to such an extent that the loads which arise in the event of a fault until the machine is stopped by the rocker lock are reduced to such an extent that there is no danger to the machine or the operator. If, for example, a coil carrier bearing is blocked, the coil carrier can be accelerated to such an extent that it rotates at the rotor speed, but as soon as the predetermined torque value is exceeded in the coupling between the coil carrier and the counterweight, this connection is released.
  • the coil carrier can be designed essentially symmetrically and the center of gravity when the coil is inserted is always in the rotor axis, regardless of whether the coil located in the coil carrier is full or empty.
  • a particularly precise setting of the torque value, in which, according to the invention, the counterweight is uncoupled from the coil carrier, can be achieved by means of a torque coupling, for example spring-loaded balls or disks.
  • a torque coupling for example spring-loaded balls or disks.
  • a shear pin can also be used as a particularly simple connecting element between the counterweight and the coil carrier, which shear pin is destroyed when the torque which can be transmitted is exceeded and thus releases the counterweight.
  • a new shear pin can then be used without any particular time or assembly effort.
  • the counterweight is rotatably mounted on the bearing ring of a coil carrier bearing, because this bearing stands still during normal operation and after the counterweight has been uncoupled only relatively low speeds can be achieved, so that this bearing is not heavily loaded.
  • the unbalanced mass of the counterweight can be dimensioned as small as possible, it is connected to the bearing via a lever arm which is as large as possible.
  • FIG. 1 shows a schematic representation of part of a rotor of a high-speed stranding machine with two coils arranged one behind the other with their coil carriers
  • FIG. 2 shows a section through FIG. 1 according to section line II-II
  • Fig. 3 is a sectional drawing of a coil support bearing with a coupled counterweight.
  • Fig. 1 are in a rotor 1 of a Schnellverseilmaschine which rotates about the rotor axis 2 at speeds that -. depending on the size of the machine - between 1000 and 5000 rpm, two coils 3 are arranged one behind the other, each of which is rotatably mounted in coil carriers 4. Windows 5 are provided in the rotor wall for replacing the coils 3.
  • the coil carriers 4 are essentially symmetrical coil brackets, the axis of rotation of which coincides with the rotor axis 2. Cut the axes of the coils 3 as well The rotor axis 2 can be seen in FIG. 2.
  • a counterweight 7 is located on the coil support bearing 6. It is connected to the coil support 4 and thus forms an unbalanced mass which prevents the coil support 4 from rotating with the rotor 1. If the coil carrier 4 is accelerated by a broken wire, damage in one of the coil carrier bearings 6, 6 'or the like, so that it begins to rotate, then when a predetermined torque value is exceeded in the coupling between the counterweight 7 and the Coil carrier 4 released the connection of these two parts.
  • the coil support bearing 6, on which the counterweight 7 is arranged is shown in a particularly advantageous embodiment according to claim 6 in detail.
  • the bearing ring 8 has an annular collar 9 on its side facing away from the coil (not shown) or the coil carrier 4 receiving it.
  • This ring collar 9 encloses at a small distance the hollow pin 10 of the coil carrier bearing 6 arranged on the rotor 1, through which the wire 11 drawn off from the coil 3 is led out.
  • the outer jacket of the collar 9 forms the inner bearing ring of a roller bearing 12 with which the counterweight 7 is rotatably mounted.
  • the bearing 12 is shut down in that the counterweight 7 is connected to the bearing ring 8 in a rotationally fixed manner by means of a torque coupling 13.
  • the torque clutch 13 in FIG. 3 consists of at least one ball 14 which is pressed into a bore 16 in the bearing ring 8 by a spring 15.
  • the torque value at which the ball 14 slides out of ⁇ - the bore 16 and thereby uncouples the counterweight 7 can be set very precisely by appropriate dimensioning of this spring load, so that it can be freely rotated relative to the coil carrier 4 via the bearing 12 and no longer participates in any further acceleration of the coil carrier 4 that occurs.
  • connection between the counterpart Weight 7 and the bearing collar 8 can also be produced by a shear pin, the strength of which is dimensioned such that it breaks at the predetermined torque value. Since the malfunctions, against the effects of which the design of the high-speed twisting machine protects, do not occur very frequently, a new shear pin can simply be used when the machine is then stopped anyway.
  • the lever arm via which the unbalanced mass of the counterweight 7 is connected to the counterweight bearing 12, should be as large as possible by means of a relatively small mass, an imbalance which prevents the bobbin 4 from rotating with the necessary certainty can be achieved.
  • the possible length of the lever arm is limited by the construction of the machine, that is to say by the free interior space available in the rotor 1 for the counterweight 7.

Abstract

Une toronneuse rapide avec au moins une bobine flottante (4) a l'interieur du rotor (1) : un balourd (7) empeche que cette bobine se mette en rotation avec le rotor. Pour empecher la mise en rotation de la bobine lors d'une exploitation normale et pour eviter la creation de balourds endommageant ou detruisant la machine lors d'une panne, il est propose une toronneuse rapide dont le centre de gravite se trouve sur l'axe de rotation et dans laquelle un balourd est relie a la bobine; ce balourd consiste en un contre-poids (7) independant et mobile autour de l'axe de rotation; lors du depassement d'un couple de rotation determine, ce balourd peut etre desaccouple de la bobine (4).
