Definitions

  • a false twisting unit having roller means mounted on a support for supporting a false twist spindle, a motor mounted on said support and motion transmitting means connecting the motor and said roller means which in turn drive the false twister.
  • This invention relates to driving and supporting arrangements for false twist spindles.
  • the invention comprises a driving and supporting arrangement for a false twist spindle comprising a support adapted for attachment to a false twist crimping machine frame, said support carrying a motor, driving and supporting roller means for the spindle, and a driving transmission between the motor and the driving roller means.
  • a preferred motor is a magnetic reluctance motor which should be capable of synchronous speeds of up to 12,000 revolutions per minute.
  • the driving transmission may give a speed ratio between the false twist spindle and the motor of approximately 100:1, and may comprise a belt engaging a pulley of the motor and engaging a wharf of a spindle driving roller.
  • the speed ratio between the said driving roller and the motor pulley may be about 5:1 and that between the false twist spindle and the driving roller about 2021.
  • the driving and supporting roller means may have magnetic means retaining the spindle in contact with a driving roller thereof.
  • the arrangement may comprise driving and/or supporting rollers for the spindle on two parallel axes, and the driving transmission may then be adapted so that the roller or rollers of either axis can be drivingly connected to the motor
  • the support may have driving and supporting roller means for two false twist spindles, and both may be driven by the same motor.
  • the two spindles preferably have separate driving and supporting roller means, and these and the driving transmission may be adapted for rotating the two false twist spindles in the same direction of rotation, or for rotating said spindles in opposite directions of rotation.
  • the roller means may comprise, for each false twist spindle, rollers on two parallel axes, the rollers on each axis having a wharf, either one of the wharves of each roller means being connectable to the motor by a single belt, which can be trained to follow different paths to drive the spindles in the desired direction of rotation.
  • the support may have an idler roller to enable the belt to be trained to follow its said different paths.
  • the motor may be adjustably mounted to enable the belt to be tensioned.
  • the support may comprise a mounting plate for the motor and for the roller means, the motor pulley and a wharf or wharves of the driving roller means projecting on one side of said plate, and the motor and the false twist spindle or spindles and the driving and/or supporting rollers therefor projecting on the other side of said plate.
  • the driving transmission may be enclosed in a casing, which may surround the motor pulley and the wharves of the rollers.
  • the casing may comprise rubber or other sound absorbing material.
  • the invention also comprises a frame and a plurality of said driving and supporting arrangements attached thereto, and power supply means for the motors thereof, which may include a frequency changer enabling the speed of rotation of the false twist spindles to be adjusted.
  • the driving and supporting arrangements may be so mounted that the false twist spindles are inclined to the vertical, the machine having yarn guide means guiding the yarn in inclined paths towards the false twist spindles.
  • FIG. 1 is a top plan of the arrangement
  • FIG. 2 is a bottom plan
  • FIG. 3 is an elevation of the embodiment in FIGS. 1 and 2, and
  • FIG. 4 is an elevation of part of a false twist crimping machine.
  • the drawings illustrate a driving and supporting arrangement for a pair of false twist spindles, 11, 12, comprising a support 13, adapted by lugs 14 for attachment to a machine frame,
  • the support 13 carries a magnetic reluctance motor 15, rollers 16, 17, 18, 19 for driving and supporting the spindles 11, 12, and permanent magnets 21, 22 for holding the spindles 11, 12 respectively in contact with the rollers 16, 17, 18 and 19 as well as a driving transmission, hereinafter described, between the motor and the rollers.
  • each false twist spindle is supported by a set of rollers separate from the set of rollers supporting the other spindle. In other words, no one roller contacts both spindles.
  • Each set of rollers comprises rollers (each roller comprising two discs axially spaced apart) on two parallel axes, the spindle being held magnetically in the nip of the rollers. If the spindle 11 is required to be driven anticlockwise as seen in FIG. 1, it is desirable for stability in high speed operation that the roller 16 should be driven, to drive the spindle 11 into the nip, while the roller 17 is an idler, driven by the spindle 11. If the roller 12 is desired to be driven clockwise as seen in FIG. 1 it is for the same reason desirable that the roller 18 should be driven while the roller 19 is an idler.
  • the driving transmission illustrated can be adapted to drive both spindles in the same direction of rotation (in either direction) or in opposite directions of rotation, and comprises a belt 23, engaging a pulley 24 of the motor 15 and a wharf of each of the driving rollers.
  • the rollers 16, 17, 18, 19 each have a wharf, 16', 17, 18, 19' and there is provided an idler roller 25 so positioned that the belt 15 can be trained either in the manner shown in full lines in FIG.
  • Belt tensioning can be by a conventional spring-loaded jockey pulley, but is most easily afforded by providing an adjustable mounting for the motor 15. As shown in FIG. 1 the motor 15 is mounted by nuts and bolts passing through three lugs 15' in the motor casing and slots in the support so that adjustment of the motor 15 towards and away from the rollers 16, 17, etc., is possible.
  • the support 13 comprises a mounting plate 26 in which the slots referred to above are formed and which holds bearings 27 for the rollers 16, 17, etc.
  • the motor 15 and rollers 16, 17, etc., project on one side of the plate 26, while the pulley 24, the wharves 16, 17 and the idler 25 project on the other side.
  • a casing 28 cast integrally with the plate 26 depends therefrom to enclose the driving transmission.
  • the casing is provided with a closure plate 29 secured by screws engaging in tapped bores in the casing, as shown in FIG. 3.
  • guiding tubes 31 fitted with ceramic eyes at each end pass through the casing in line with the spindles 11, 12.
  • the unit can be mounted on the machine by an antivibration mounting, and the casing can be made soundthe frame to the spindle, giving smoother and quieter running at speed.
  • the units 41 can be mounted on the machine frame 42 so that the spindles '43 are inclined to the vertical, so that a straight threadline can be obtained even with an inclined heater 44.
  • a reluctance motor taking about 180 watts of power is capable of driving two spindles at speeds of 1 million revolutions per minute or higher. With a step-up ratio of about 20:1 between the rollers 16, 17, etc., and the spindles 11, 12, and a step-up ratio of about 5:1 between the pulley 24 and the wharves 16', 17', etc., this requires a motor speed of about 10,000 revolutions per minute.
  • the starting characteristics of a reluctance motor are ideal for this use, and it is capable of maintaining a given synchronous speed despite quite wide variations in the power demanded to drive the spindles.
  • the power consumption per spindle is less than with the present arrangement in which a belt drive common to all the spindles is driven from a single large motor.
  • a frequency changer is provided in a common power supply to all the motors of a multistation false twist crimping machine so that they can all be driven at the same speed which can be adjusted.
  • Reversing switches can be fitted individually to the motors, or in the common power supply.
  • a false twisting unit for use in false twist crimping machines, comprising support means; at least one false twist spindle; roller means carried by said support means for supporting said false twist spindle in predetermined position relative thereto, and for driving it in rotation; electric motor means mounted on said support means; motion-transmitting means cooperating with said motor means and roller means for rotating the latter and thereby driving said false twist spindle in rotation; and connecting means on said support means for detachably connecting said unit to a false twist crimping machine.
  • roller means are so mounted that the false twist spindles are inclined to the vertical, and the machine has yarn guide means guiding the yarn in inclined paths towards the false twist spindles.
  • said motion-transmitting means comprising an output shaft on said motor means, a pulley on said output shaft, a wharf provided on said roller means, and a belt trained about said pulley and contacting said wharf for rotating the latter in response to rotation of the former.
  • a false twisting unit as defined in claim 8 said motion-transmitting means being constructed and arranged so that said wharf rotates at a speed which is higher than that of said pulley by a ratio of substantially 5:1.
  • a false twisting unit as defined in claim 1, said motion-transmitting means comprising at least two rollers one of which is driven at a predetermined rotary speed; and wherein said false twist spindle is driven by said roller means at a speed of rotation which is higher than said predetermined speed by a ratio of substantially 20:1.
  • a false twisting unit as defined in claim 1 said roller means comprising at least two rollers one of which is an idler roller and the other of which is a driven roller; and said motion-transmitting means being operative for effecting driving of either one of said rollers at the will of an operator.
  • a false twisting unit as defined in claim 16 said motion-transmitting means including a rotatable output shaft of said motor means, a pulley on said output shaft, a wharf on each of said rollers, a drive belt trained about said pulley and engageable with the wharf on one roller of each of said pairs; and further comprising at least one idler roller on said support means for enabling training of said belt to follow different paths in dependence upon the desired direction of rotation of said false twisting spindles.
  • said motion-transmitting means comprising belt drive means for transmitting motion from said motor means to said roller means and including a drive belt; and belt tensioning means on said support means for tensioning said belt.
  • said motion-transmitting means comprising belt drive means for transmitting motion from said motor means to said roller means and including a drive belt; and mounting means mounting said motor means on said support means for positional adjustment with reference to the latter so as to permit tensioning of said drive belt.
  • roller means have magnetic means retaining the spindle in contact with a driving roller thereof.
