Definitions

  • This invention relates to yarn winding apparatus, and in particular to apparatus for traversing a running yarn to and fro parallel with the surface of a package on which the yarn is being wound.
  • the yarn is engaged by a yarn guide mounted on a reciprocating rod.
  • the yarn is engaged in a helical groove, or by a guide held in a helical groove, provided in the surface of a roller rotating about an axis parallel with that of the package.
  • the yarn is successively engaged by two yarn guides which are each mounted on one of two oppositely moving endless belts.
  • the yarn may be successively engaged by each of two oppositely rotating guide arms.
  • Each of these known types of traversing apparatus has its own disadvantages, mainly related to the inertia of the moving parts at the turnround points at the two ends of the traverse stroke, the transfer of the yarn from one groove or guide to another, or the ability to provide in the apparatus means for avoiding patterning on the package and/or ridged or collapsed package ends.
  • mechanisms and arrangements have been devised in order to avoid or minimise the disadvantages pertaining to the particular type of traverse apparatus, with varying degrees of success.
  • all of such mechanisms and arrangements tend to complicate the traverse apparatus and increase considerably the cost of the textile machine on which such traverse apparatuses are fitted.
  • Traverse mechanisms as described above require lubrication, frequent maintenance and adjustment, and tend to be very noisy. Furthermore such traverse mechanisms are designed such that the turn round characteristics are as good as can be achieved with the design concerned at the maximum design speed of operation of the mechanism. In consequence, when the machine is run at a lesser speed or wind angle as may be desirable for certain yarn processing applications, the dwell time at the end of each stroke is increased, thereby increasing the problems of ridged or collapsed package ends.
  • the invention provides a yarn winding apparatus comprising yarn guide means, drive means, coupling means and control means, whereby the drive means is continuously operable in a driving direction, the coupling means is operable in a first operating condition to engage the yarn guide means with the drive means whereby the yarn guide means is driven in one direction to move the yarn in a first direction along a traverse path and then in a second operating condition to re-engage the yarn guide means with the drive means whereby the yarn guide means is driven in the opposed direction to move the yarn in the reverse direction along the traverse path, and the control means is operable to change the coupling means from one to the other of the operating conditions when the yarn reaches a predetermined location on the traverse path.
  • the yarn guide means may comprise a yarn guide mounted on an endless band.
  • the band may be a belt, cable or cord, and may be disposed to travel around two spaced pulleys mounted for rotation about substantially parallel axes.
  • the yarn guide means may comprise a cam roller having a helical groove in the cylindrical surface thereof.
  • the coupling means may comprise two clutches, each clutch having an output side drivingly engaged with the yarn guide means. In this case, in the first operating condition, one clutch is engaged and the other clutch is disengaged, and in the second operating condition the one clutch is disengaged and the other clutch is engaged.
  • the drive means may comprise two motors, each motor being continuously operable in a respective driving direction and drivingly engaged with a respective one of the clutches whereby the input sides of the clutches are driven in opposed directions.
  • a single motor continuously operable in a driving direction may be drivingly engaged with the two clutches whereby the input sides of the clutches are driven in opposed directions.
  • the control means may comprise programmable means, in which case the predetermined location on the traverse path, reached by the yarn when the coupling means is changed from one operating condition to the other operating condition, may be varied for successive motions of the yarn along the traverse path.
  • the control means may also be operable to vary the speed of rotation of the drive means during the changes of operating condition of the coupling means and/or between successive changes thereof.
  • the clutches may each comprise an electrorheological fluid or magneto-rheological suspension clutch, whereby the control means is operable to electrically energise the fluid or magnetically energise the suspension of one clutch and de-energise the fluid or suspension of the other clutch to change the coupling means from one operating condition to the other operating condition.
  • a package 10 rotatably mounted in a cradle 11 of a textile machine, and on which a yarn 12 is being wound.
  • the package 10 is driven by contact of its peripheral surface with that of a driving bowl (not shown), which is itself driven at a constant speed of rotation so that the speed of take-up of the yarn 12 by the package 10 is substantially constant as the package diameter increases.
  • a driving bowl not shown
  • the guide 13 is secured to an endless band in the form of a toothed belt 14 which passes around two toothed pulleys 15, 16.
  • the motion of the guide 13 along the upper span of the belt 14 defines a traverse path which is substantially parallel with the axis 17 of the package 10.
  • an endless cable or cord may be used to minimise the inertia of the moving parts, which cable or cord may make more than one complete wrap around the surface of each pulley 15,16.
  • Each pulley, 15, 16 is associated with a respective synchronous motor 18, 19, and each motor 18, 19 is continuously operable to rotate in its respective drive direction, in this case anti-clockwise for motor 18 and clockwise for motor 19 as shown by arrows R.
  • the speed of the motors 18,19 may be controlled from a single line inverter (not shown) for the whole textile machine.
  • Disposed between each motor 18, 19 and its respective pulley 15, 16 is a respective clutch 20, 21.
  • a control means 22 is connected to both clutches 20, 21 and both motors 18, 19 via connections 24, 23 respectively so that when the yarn guide 13 has reached a predetermined location in the traverse path, ie the left hand end of the traverse stroke, the clutch 20 is disengaged by the control means 22 and the clutch 21 is simultaneously engaged.
  • the apparatus is then in the second operating condition and pulley 16 is driven in a clockwise direction to move the belt 14 and yarn guide 13 towards pulley 16.
  • Pulley 15 is at this time freely rotatable.
  • control means 22 disengages clutch 21 and re-engages clutch 20 via connections 24 to put the apparatus once again in the first operating condition and move the yarn guide 13 towards pulley 15. Operation of the control means 22 to change the operating condition of the apparatus, and hence the direction of travel of the yarn guide 13, may be determined by the control means 22 being responsive to the elapsed time since the previous operating condition change and the speed of rotation of the motors 18, 19 as indicated through the connections 23 from sensors 25.
  • control means 22 may be responsive to a signal from a position sensor 26 detecting a marker 27 on the belt 14, or a signal from an encoder (not shown) coupled with one of the pulleys 15, 16 to determine the angular disposition thereof.
  • the signals from sensors 25 or 26, or encoder could be fed forwardly to compensate for any delay in the clutch torque response to the applied voltage.
  • a temperature compensation may also be built in.
  • the clutches 20, 21 may be mechanical, in which case the connections 24 may be mechanical or electrical, or may be magnetic, piezo-electric or magnetostictive driven friction clutches in which case the connections 24 may be electrical. However in the embodiment shown in Figs 1 and 2 and described herein it is preferred that the clutches 20, 21 are electrorheological fluid or magneto-rheological suspension clutches and that the connections 24 are electrical. With such clutches 20, 21 the time to engage and disengage is considerably less than with mechanical or magnetic clutches, and wear, maintenance and lubrication are all considerably reduced.
  • the control means 22 via the appropriate connection 24 causes excitation of the relevant clutch so as to cause a voltage to energise an electrorheological fluid or a magnetic field to energise a magneto-rheological suspension disposed between the input and output sides of the clutch, whereby the fluid or suspension substantially instantaneously becomes effectively solid to provide a positive driving connection between the two sides of the clutch.
  • the control means 22 cuts off the excitation of the other clutch so that substantially instantaneously the electrorheological fluid or magneto-rheological suspension in that clutch reverts to its liquid or suspension state and the driving connection between the two sides of that clutch is removed.
  • the apparatus of the present invention has particular advantage in that the only parts thereof which reverse their direction of rotation are the pulleys 15, 16, the band 14 and the yarn guide 13, a combination of parts having very little inertia.
  • the motors 18, 19 may be of relatively small power output compared with motors used to drive known traverse mechanisms which have much greater inertia.
  • the turn round time of the traversing parts 13,14,15 and 16 is independent of the winding speed or wind angle so that the problems of ridged or collapsed package ends are not increased when winding at lesser winding speeds or wind angles than the maximum design values.
  • control means 22 is programmable so that the position of the ends of the stroke and the stroke length can be varied as the package 10 is wound in accordance with any desired programme. Also the rotational speed of the motors 18, 19 and hence the speed of traverse of the yarn guide 13 can be varied either during a traverse stroke and/or as the package 10 is wound in accordance with any desired programme. By this means patterning and ribbed or collapsed package ends can be avoided, as well as packages of any desired taper can be built.
  • the programme preferably synchronises the stroke end position and yarn guide traverse speed variations so that the yarn tension variation throughout the package build is minimised.
  • the motor 18 drives pulley 32, belt 33, pulley 34 and the input side of the clutch 20 in one direction together with pulley 35, belt 36 and jockey pulley 37, whilst pulley 38 and the input side of clutch 21 are driven in the opposite direction.
  • Whichever clutch 20 or 21 is energised at any given instant, that clutch provided that the single scroll cam roller 39 is driven in the corresponding rotational direction, which is reversed as that clutch is disengaged and the other clutch is engaged.
  • the yarn 12 may be guided directly by the helical groove 40 in the cylindrical surface of the cam roller 39, or by a guide (not shown) constrained to travel in the groove 40 in a reciprocating path parallel with the package axis 17.
  • a traverse mechanism having the flexibility to better optimise the package build parameters than prior art traverse mechanisms, in particular the ability to maintain a constant wind angle, infinite adjustment of the taper angle, taper at one end only if desired and faster turnround at a lower traverse speeds.
  • Other benefits provided by the traverse mechanism of the invention are low noise levels, no lubricating oil requirement and individual traverse mechanism maintenance on the textile machine.
