Definitions

  • This invention relates to an accumulator for a twisting or stranding apparatus for lengths of filamentary material and to a twisting or stranding apparatus.
  • At least one accumulator of material, or two accumulators in series are used.
  • Conventional accumulators each comprise two accumulator rolls which are disposed radially spaced-apart along the feed path of the material and with their rotational axes parallel so that their axes extend normal to the feed paths.
  • a length of material to be stranded or twisted is fed onto the accumulator by passing the material partly around each roll and from roll to roll.
  • the maximum length of filamentary material which may be accommodated upon an accumulator i.e. maximum accumulator capacity
  • the maximum length of filamentary material which may be accommodated upon an accumulator is dependent upon the roll diameters, the distance apart of the rolls, and the number of passes of material between rolls which, of course, is dependent upon the axial length of the rolls.
  • a conventional accumulator is caused to rotate about the feed path of the material, i.e. about a plane normal to the axial direction of the rolls, to provide a twist in the material as it enters an accumulator.
  • the resultant twist i.e. that in the material after it has left the accumulator, is a function of the material speed of the whole accumulator about the feedpath, and the entry and exit speed of the material into and from the accumulator.
  • the SZ twist is found to have particular electrical advantages in twisted or stranded electrical cable or telecommunications cable. It is well known in the cable art as is exemplified in a paper "SZ Twisting and Stranding of Communications Cables Using Rotating Accumulators With Periodically Changing Capacity" by D. Vogelsberg as published in Proceedings of 20th International Wire and Cable Symposium.
  • the invention provides an accumulator for a twisting or stranding apparatus for lengths of filamentary material characterized in that it has at least two accumulator rolls which are in radial alignment, 'radially spaced apart and rotatable about substantially parallel individual axes while both are rotatable together about a common accumulator axis which is substantially parallel to the individual axes with at least one of the rolls being movable around an accumulator capacity change axis spaced from and parallel to the individual axes, towards and away from the other roll to decrease and increase the capacity of the accumulator, and means to drive the rolls about the common axis to twist or strand said lengths and simultaneously to rotatably move the at least one roll towards and away from the other roll.
  • the invention envisages the use of two accumulator rolls with one or both rolls being movable around said capacity change axis. In a case particularly where one only of the rolls is movable around the capacity change axis, this axis may be coincident with the common axis.
  • the rolls are preferably movable in synchronism towards and away from the other rolls to decrease and increase the capacity of the accumulator between minimum and maximum capacities.
  • the rolls are spaced apart around the common accumulator axis and are movable in unison around individual capacity change axes between closely spaced positions near to the accumulator axis (i.e. for minimum capacity), and widely spaced positions further from the accumulator axis. Such movement is radial with respect to the accumulator axis.
  • the means to drive the rolls comprises a sun gear and planet gears drivably connected to the sun gear, with the rolls being mounted one upon each of the planet gears.
  • Rotation of the planet gears at a desired relative speed to the rotational speed of the sun gear moves the rolls into and out of maximum and minimum capacity positions of the accumulator at a required rate while the actual rotational speed of the sun gear controls the amount of twist given to filamentary material as it moves onto the accumulator and thus effects the final twist.
  • the accumulator when forming part of a twisting or stranding apparatus is disposed with the common accumulator axis disposed extending generally in the feed direction of the filamentary material.
  • a twisting or stranding apparatus for lengths of filamentary material comprises a nipple 10 and accumulator 12 downstream from the nipple.
  • the nipple is of conventional design and is used to group together all of the different lengths 14 of filamentary which it is required to twist together.
  • the accumulator is a changing capacity accumulator for the purpose of providing "SZ" twist in the grouped lengths 16 of material while the input speed of the lengths onto the accumulator is controllably varied and the output speed is constant.
  • the method of varying or maintaining constant the input and output speeds of material fed through the apparatus is conventional and will be discussed no further.
  • the apparatus of this embodiment differs from conventional apparatus in the construction of accumulator 12.
  • accumulator 12 comprises three accumulator rolls 17, each rotatably mounted upon its individual axis at one end of an arm 18.
  • the three arms 18 are secured by their other ends to three planet gears 20, one to each planet gear.
  • Each arm is non-rotatable relative to its planet gear and extends radially of the planet gear to locate its roll 17 out beyond the periphery of the gear.
  • the three planet gears form part of a means to drive the rolls about a common accumulator axis and simultaneously to rotatably move the rolls towards and away from each other as will be described.
  • This means also includes a sun gear 22 around which the planet gears are equally spaced apart and in driving engagement with the sun gear, the planet gears being retained in their relative positions by a trilateral planetary carrier 24 at the three corners of which the gears 20 are freely rotatably mounted.
  • the planetary carrier 24 is rotatable at any desired speed about an axis, coincident with the sun gear axis, i.e. about a common accumulator axis by means of a hollow driving shaft 26, to which the carrier is coaxially secured.
  • the shaft 26 is mounted within bearings 28 within a frame 30 of the apparatus.
  • the sun gear 22 is independently rotatable upon a separate hollow shaft 32 concentrically mounted within the shaft 26 by means of bearings 34.
  • the two shafts are driven, respectively, by means of driving pulley wheels 36, 38 and an associated driving mechanism (not shown) by which the relative rotational speeds of the sun and planet gears may be varied as desired.
  • the accumulator is disposed with the common accumulator axis extending along and the individual roll axes extending parallel to the general feed direction of the grouped lengths 16 of material passing through the apparatus.
  • the lengths 16 are fed from the nipple, and along the accumulator axis through the shaft 32.
  • the lengths Upon reaching the end of shaft 32, the lengths extend around an end 40 of the shaft, which is suitably rounded and surface treated to minimize wear upon the material by friction, and radially outwardly to the rolls 17.
  • Each roll is formed with a plurality of spaced annular grooves 42 and the lengths 16 of material pass from one roll to another in turns around the accumulator, the adjacent turns being separated by their being contained and guided within adjacent grooves 42 as shown by Figure 1.
  • the lengths 16 are fed around a freely rotatable guide wheel 44 before proceeding, as twisted material, to a subsequent manufacturing process (not described).
  • the wheel 44 is suitably secured to, or relative to, the planetary carrier 24 to ensure it is permanently oriented in a fixed position relative to the final roll 17 (i.e. the lower roll in Figure 1) around which the lengths 16 turn before proceeding to wheel 44.
  • the ingoing speed of the lengths 16 through shaft 26 is suitably varied (in known manner) to provide "SZ" twist in the lengths leaving the accumulator at constant velocity around the wheel 44.
  • Accumulator change in capacity is effected by moving the rolls 17 from innermost ( Figure 4), or closely spaced positions in which the rolls axially overlap the sun gear and lie close to its axis, to outermost or widely spaced positions ( Figure 2).
  • the change in capacity from the minimum to the maximum as shown by those figures, is reflected by the difference in the distances between the rolls in Figures 2 and 4.
  • each half revolution of the planet gears 22 turns the arms 18 from the innermost positions of Figure 4 to the outermost position of Figure 2 by rotation around the axes of the planet gears 20, these axes thus providing the function of accumulator capacity change axes.
  • a further half revolution of the planet gear, continuing in the same direction, returns the arms to their innermost positions.
  • a twisting or stranding apparatus has two in-tandem accumulators 12 each of the same design as the accumulator in the first embodiment.
  • the downstream accumulator is reversed in position along the feedpath and is separated from the upstream accumulator by the use of the guide wheel 44 and another guide wheel 46 to guide the lengths 16 of material onto the rolls 17 of the downstream accumulator.
  • This apparatus which has similar advantages to those discussed for the first embodiment, controls the 'SZ' twist lay operation by reducing the capacity of each accumulator as the other increases together with a required velocity change of the material as it moves along the feedpath between the accumulators.
  • Figure 5 shows the upstream accumulator in its maximum capacity position and the downstream accumulator in its minimum capacity position. Both accumulators rotate, i.e. the sun and planet gears, around the common axis at a constant speed.
  • inlet and outlet speeds of the lengths of material are constant as is normal in conventional apparatus employing conventional accumulators in tandem.
  • an accumulator according to the invention does not change its capacity linearly between minimum and maximum capacities. This is because the rolls 17 rotate around the centres of planet gears 20 and do not progress linearly towards and away from the centre of sun gear 22. This results in a change in rate of charge and discharge of each accumulator.
  • two accumulators are used in tandem and 180° out of phase, then each exactly compensates for any change in rate of the other to thereby produce a constant ingoing and outgoing speed. It should be borne in mind, however, that in view of the above characteristics of the single accumulator, it cannot be used in tandem with a conventional accumulator which changes its capacity in linear fashion.
