Definitions

  • the present invention relates to a draw texturing machine provided with a pin-type twisting unit.
  • Patent Literature 1 Japanese Laid-Open Patent Publication No. 2002-69763 discloses a pin-type twisting unit (pin-twister-type false-twisting device in Patent Literature 1) which twists a yarn running inside a rotating pin (spinner in Patent Literature 1).
  • pin-type twisting unit rollers are attached to two rotational shafts, respectively, and a cylindrical pin is retained by magnet while being in contact with the circumferential surfaces of the rollers.
  • the rotational shafts is rotationally driven by a motor, the pin in contact with the rollers rotates about the shaft, with the result that the yarn running inside the pin is twisted.
  • the pin keeps rotating until the operator stops the rotation of the pin, even after yarn breakage occurs and packages are no longer produced. This causes problems such as wasteful power consumption and reduction in life of members constituting the pin-type twisting unit due to abrasion. Furthermore, because the pin is retained only by the magnets, the pin may be detached and drop off for some reason if the pin keeps rotating after yarn breakage. When the pin drops off, another device may be damaged, or the pin may be lost.
  • an object of the present invention is to swiftly stop the rotation of a pin at the time of yarn breakage, in a draw texturing machine including a pin-type twisting unit.

  • the control unit automatically stops the motor of the pin-type twisting unit. It is therefore possible to swiftly stop the rotation of the pin at the time of the occurrence of yarn breakage, without waiting for the stop of the motor by the operator.
  • the present invention is preferably arranged such that the draw texturing machine further includes: a tension sensor configured to detect tension of the yarn; and a cutter by which the yarn is cut, wherein, when the tension of the yarn detected by the tension sensor exceeds a predetermined upper limit value or falls below a predetermined lower limit value, the control unit causes the cutter to cut the yarn and stops the motor.
  • the present invention is preferably arranged such that, when the tension of the yarn detected by the tension sensor exceeds the upper limit value or falls below the lower limit value, the control unit causes the cutter to cut the yarn and then sends a stop instruction to the motor.
  • the motor is preferably stopped as soon as possible.
  • the motor starts deceleration before the cutter cuts the yarn, the running speed of the yarns and the rotation speed of the pin become imbalanced, with the result that the pin may be detached on account of inconsistent action of the yarn.
  • a stop instruction is sent to the motor after the cutter cuts the yarn as described above.
  • the present invention is preferably arranged such that an absolute value of deceleration of the pin when the pin is stopped is larger than an absolute value of acceleration of the pin when the pin is accelerated.
  • the draw texturing machine further includes a notification unit which is switchable to a notification state of notifying predetermined information to an operator, wherein, the control unit switches the notification unit to the notification state when stopping the motor.
  • the present invention is preferably arranged such that, processing units in each of which a yarn path is formed to pass the pin-type twisting unit and the yarn breakage sensor are provided to be lined up, and the control unit stops the motor of the pin-type twisting unit of a processing unit where yarn breakage is detected by the yarn breakage sensor.

  • the control unit 30 sends a stop instruction to the motor 54 to stop the rotation of the motor 54 (pin 41) (step S5).
  • the control unit 30 switches the notification unit 27 to a notification state. This allows the operator to recognize that the yarn Y has been cut and the rotation of the pin 41 has been stopped.
  • the control unit 30 automatically stops the motor 54 of the pin-type twisting unit 15. It is therefore possible to swiftly stop the rotation of the pin 41 at the time of the occurrence of yarn breakage, without waiting for the stop of the motor 54 by the operator.
  • the control unit 30 when the tension of the yarn Y detected by the tension sensor 24 exceeds the predetermined upper limit value or falls below the predetermined lower limit value, the control unit 30 causes the cutter 23 to cut the yarn Y and stops the motor 54 of the pin-type twisting unit 15.

  • the yarn Y is cut by the cutter 23 when the tension of the yarn Y exceeds the predetermined upper limit value or falls below the predetermined lower limit value, the occurrence of sudden yarn breakage and production of a low-quality package P are restrained. Furthermore, because the motor 54 of the pin-type twisting unit 15 is stopped at this time, unnecessary rotation of the pin 41 after the yarn Y is cut is avoided.
  • the control unit 30 sends a stop instruction to the motor 54 of the pin-type twisting unit 15 after causing the cutter 23 to cut the yarn Y.
  • the motor 54 is preferably stopped as soon as possible.

  • a stop instruction is sent to the motor 54 after the cutter 23 cuts the yarn Y as described above. With this arrangement, the motor 54 does not start deceleration before the yarn Y is cut, and hence detachment of the pin 41 is restrained.
  • the absolute value of the deceleration of the pin 41 when the pin 41 of the pin-type twisting unit 15 is stopped is larger than the absolute value of the acceleration of the pin 41 when the pin 41 is accelerated. Because the deceleration of the pin 41 is arranged to be relatively high in this way, the rotation of the pin 41 is swiftly stopped, and the time of unnecessary rotation of the pin 41 after the yarn breakage is shortened.
  • the notification unit 27 which is switchable to the notification state of notifying predetermined information to the operator is further provided, and when the motor 54 of the pin-type twisting unit 15 is stopped, the control unit 30 switches the notification unit 27 to the notification state (a state in which a lamp turns on or flickers).
