Definitions

  • the present invention relates to the drive for a spindle of a textile machine of the ring spinning doubling and twisting frame type, to be referred to generally herein as ring frames.
  • AC motors have been explored to drive individually the spindle of the ring frame. Although this arrangement is capable of producing the necessary torque for winding yarn onto a package former placed on the spindle, the motor is not easily controllable especially at the beginning and at the end of the spinning operation. Furthermore, the AC motor does not generate any significant torque when stationary.
  • the present invention aims to provide a system to improve the yarn winding, piecing and doffing operations.
  • the apparatus according to the present invention is characterised by the features of claim 1.
  • a switched reluctance drive motor of the type disclosed in GB-A-1, 597,486, can be controlled to operate in the required manner during the piecing and winding of the yarn, and provide a much more efficient automatic doffing operation than hitherto.
  • the present invention also provides a method of operating a ring frame (as herein defined) characterised by the features of claim 5.
  • a third aspect of the present invention provides a method of doffing a ring frame (as herein defined) characterised by the features of claim 7.
  • a fourth aspect of the present invention provides a method of piecing a spindle position of a ring frame (as herein defined) characterised by the features of claim 9.
  • a spindle 10 is in this embodiment fixedly attached to an annular member 12 carrying a yarn cutter 13, and to the motor shaft 14 of a switched reluctance drive motor 18, for example of the type disclosed in GB-A-1,596,486.
  • Control to the switched reluctance drive motor 18 is provided by means of a control system which incorporates two controllers 16 and 50 to be described later.
  • the controller 16 is a local controller to the individual spindle position illustrated and is capable of determining the speed and acceleration of the switched reluctance drive motor 18 and of controlling the torque applied both while the motor is stationary and while it is rotating.
  • the controller 50 is a global controller covering several spindle positions, for example all of the spindle positions down one side of a double sided machine, or even an entire multi-position machine, and operates by instructing the local controller of each individual spindle position to ensure synchronization of the various spindle positions under its control and to ensure that the spindle positions of the entire machine execute a desired simultaneous operation such as controlled acceleration upon start-up or controlled deceleration upon shut-down, for example prior to a doff.
  • the control line between the local controller 16 and the switched reluctance drive motor 18 includes a feedback from the motor to the local controller in order that the controller is aware of the status of the motor 18 and can verify that the instructed operation of the motor is being achieved in practice.
  • the local controller 16 may be capable of instructing two or more separate torque values from the switched reluctance drive motor 18 such that a higher holding torque may be applied by the motor when stationary, when required during a manual or an automatic doff, and a lower holding torque may otherwise be provided such that the motor will remain stationary in the absence of external influences and is capable of controlled rotation subject to an external mechanical influence, for example unwinding of the yarn on its spindle by an operator during a manual doff.
  • the control lines between the global controller 50 and the various local controllers 16 subordinate to it will include a feedback of the status of the individual drive motors, to allow the global controller to verify the status of the drive motors under its control.
  • the advantage of having both a local controller and a global controller is that it is possible to isolate the control function from the global controller, for example when piecing after an end break, so as to allow localized control of one particular spindle position, whereas otherwise the operation of each of the spindle positions will be under the control of the global controller, and this will even apply to the operation of all of the other normally-functioning spindle positions during piecing of one particular spindle position following an end break.
  • the spindle 10 is set to rotate at a preset speed by the global controller 50 and yarn strand 22 passes through the traveller 28 and onto the package former 20 also at a constant speed by means of the delivery rollers 24.
  • the rings 30 carrying the travellers 28 are moved to their lowermost positions by descent of the ring rail 32.
  • the feed of yarn will then transfer itself from the package former to the annular member 12 on the spindle and this operation is controlled to ensure that at least a few turns of the yarn are made onto the annular member to hold the yarn. In doing so, the yarn will pass between two consecutive radially extending blades of the yarn cutter 13.
  • the motor 18 is then controlled to stop completely and to hold its rest position by virtue of a holding torque set by the local controller 16 instructed by the global controller 50.
  • the doffer unit (not shown) descends onto the loaded package former 20 and lifts it off the spindle 10 while causing the yarn between the package former 20 and the annular member 12 to be cut by one of the blades of the yarn cutter 13.
  • the motor torque is controlled at a higher level (by means of the local controller 16) during this lifting action to provide the required yarn tension for yarn cutting.
  • This lifting.and the resulting tension on the yarn which imposes an unwinding action on the few turns carried by the annular member 12 would, in the absence of braking effort on the spindle, together turn the spindle.
  • the yarn remains threaded up through the traveller 28 and on the annular member 12 and is strained by the high holding torque in the motor 18.
  • the loaded package former 20 lifted from the spindle is then replaced by an empty one.
  • the build-up of yarn on the annular member 12 is removed by any suitable means, not shown.
  • the piecing operation may be effected either manually or automatically.
  • the local controller 16 will be operated by the operator to apply a low holding torque during which time the operator can pay out a length of yarn for connecting back to the yarn strand at the delivery rollers 24 by manually pulling that yarn to rotate the partially loaded package former against the low holding torque of the drive motor 18, until sufficient yarn has been paid out to enable the operator to twist together the yarn strand at the delivery rollers 24 with the yarn 22 shown in the balloon in the drawing, at which point the operator can release the spindle to accelerate to normal operating speed.
  • the yarn strand will be delivered continuously by the delivery rollers up to the instant of twisting together, and will preferably be sucked away to waste.
  • the reversal of the package former to pay out yarn for the automatic connection to the yarn strand at the delivery rollers 24 is effected by the local controller 16 reversing the motor to pay out yarn which can then be caught (for example by a suction nozzle) and fed back to the delivery rollers 24 for connection.
  • the spindle motor 18 is then controlled for rapid acceleration to re-­establish the balloon of yarn shown at 22 and then to return to normal operating speed.
  • connection of the yarn back to the yarn strand at the delivery rollers 24 may be achieved while the motor 18 is momentarily held at a speed of rotation suitable for the connecting operation, and the motor 18 then accelerated up to normal operating speed to re-establish spinning with the minimum of substandard yarn where the accelerating spindle is unable to match the constant delivery rate of the delivery rollers.
