  • FIG. 1 is a diagram showing an example of the general configuration of a winding unit in a conventional automatic winder.
  • the winding unit 1 includes a yarn supplying bobbin 3 located at the bottom of the winding unit 1 and insertingly installed upright on a tray 2 and a yarn winding device 4 located at the top of the winding unit 1 to wind a yarn Y unwound from the yarn supplying bobbin 3 into a package P.
  • a yarn unwinding assisting device 5, a tension applying portion 6, a splicer (yarn splicing device) 7, and a slub catcher 8 are provided in this order along a yarn path between the yarn supplying bobbin 3 and the yarn winding device 4; the yarn unwinding assisting device 5 is located lowest among these members.
  • the slub catcher 8 includes an integral or separate cutter (not shown in the drawings) so that when a yarn defect is detected, the corresponding portion can be immediately cut with the cutter.
  • a package P side yarn end and a yarn supplying bobbin 3 side yarn end resulting from the cutting are guided to the splicer 7 by yarn end catching portion (not shown in the drawings) for catching the respective yarn ends using suction air.
  • the splicer 7 then splices the yarn ends.
  • Guides 9, 10, 11 are provided, for example, above and below the slub catcher 8 and below the splicer 7 to guide the traveling yarn Y.
  • a plate 12 is provided in a direction crossing the yarn path.
  • a U-shaped guide groove 13 is formed in the plate 12.
  • the guide groove 13 is substantially formed of and partitioned by a hard chip such as ceramic.
  • the yarn winding device 4 includes a traverse drum 15 rotated by a driving drum 14, and a cradle 16 that supports the package P so that the package P can rotate in contact with the traverse drum 15 under an appropriate pressure.
  • a traverse groove 17 is formed in a peripheral surface of the traverse drum 15 to wind the yarn Y into the package P while traversing the yarn Y over an appropriate range.
  • the driving drum 14 is driven by a motor (not shown in the drawings).
  • the tension applying portion 6 conventionally adjusts winding tension based on empirical rules. That is, the tension applying portion 6 reduces the tension with increasing winding diameter of the package P so as to set the winding density of the package P to an ideal value.
  • the cradle 16, which supports the package P is linked to the tension applying portion 6 via a lever link mechanism so as to reduce the tension exerted by the tension applying portion 6 in a correlation with movement of the cradle 16.

  • the controller outputs a control signal to a motor (not shown in the drawings) that drives the driving drum 14, which drives the traverse drum 15, to control the rotation number of the motor to change the peripheral speed of the package P.
  • the European Patent Application EP 0 881 185 A2 discloses a method to control and adjust the tension in a yarn manufacturing process according to the Prior Art.
  • the winding unit 1 includes a large number of components such as the yarn unwinding assisting device 5, the tension applying portion 6, the splicer 7, the slub catcher 8, and the yarn winding device 4 which are provided in the winding unit 1 along the yarn path. Any of the components may malfunction during operation. When any component malfunctions during operation, detecting which of the components is malfunctioning is difficult.
  • An object of the present invention is to provide an automatic winder that detects any malfunctioning winding unit component to be easily based on a tension measured value from a tension sensor measuring the winding tension of a yarn being wound, and a method of detecting malfunctioning in the automatic winder.
  • the present invention provides an automatic winder including a winding unit guiding a yarn unwound from a yarn supplying bobbin through a yarn path to a yarn winding device and winding the yarn into a package in the yarn winding device to manufacture the package.
  • the winding unit comprises a tension sensor measuring tension of the yarn.
  • the automatic winder includes a component malfunction detecting section for detecting any of a plurality of components of the winding unit which is malfunctioning, based on a tension measured value detected by the tension sensor.
  • the component malfunction detecting section can detect which of the components is malfunctioning based on the tension change condition measured by the tension sensor. For example, the component malfunction detecting section pre-stores a tension change pattern for each of the components which is observed when the component malfunctions. Then, which of the components is malfunctioning can be easily detected by comparing a change in the tension measured value obtained by the tension sensor with the stored tension change patterns.
  • the component malfunction detecting section has a storage section in which a plurality of tension patterns are stored, the plurality tension patterns are an optimum winding tension and tension patterns obtained when the respective components malfunction, and when a tension measured value obtained by the tension sensor (18) deviates from the optimum tension pattern, the tension measured value is compared with each of the tension patterns obtained when the respective components malfunction, to determine a malfunctioning component. Thus, the malfunctioning component is determined.
  • the automatic winder includes a tension applying portion applying tension to the yarn passing through the yarn path and a driving section driving the tension applying portion.
  • the tension measured value obtained by the tension sensor is fed back to a controller which then controls the tension applied by the tension applying portion.
  • the component malfunction detecting section determines that the tension applying portion is malfunctioning when the tension remains unchanged even through the controller transmits an appropriate tension applying portion control signal to the driving section for the tension applying portion based on the tension measured value.
  • the tension applying portion is defective, even though the controller transmits an appropriate tension applying portion control signal to the tension applying portion based on the tension measured value, the tension applying portion fails to apply the appropriate tension to the yarn according to the tension applying portion control signal.
  • the component malfunction detecting section easily determines that the tension applying portion is malfunctioning.
  • An away-from-tension applying portion condition can be similarly sensed in which the tension applying portion per se is not defective but the yarn fails to pass through the tension applying portion and travels away from the tension applying portion.
  • the automatic winder includes a controller controlling rotation number of a motor driving the yarn winding device to control the tension of the yarn passing through the yarn path.
  • the tension measured value obtained by the tension sensor is fed back to the controller which then controls the tension.
  • the component malfunction detecting section determines that the yarn winding device is malfunctioning.
  • the yarn winding device including the traverse drum, the driving drum, the drum driving motor, and the cradle is defective
  • the controller transmits the appropriate control signal to the motor based on the tension measured value
  • the package fails to be properly rotated according to the control signal. This prevents the appropriate tension from being applied to the yarn. Therefore, where the tension remains unchanged even though the component malfunction detecting means transmits the appropriate motor control signal to the motor based on tension measured value, the component malfunction detecting section can easily determine that the yarn winding device is defective.
  • the automatic winder is characterized in that the component malfunction detecting section determines that the yarn supplying bobbin has fallen down when a tension change in a particular waveform is observed in the tension measured value obtained by the tension sensor.
  • the tension applied to the yarn exhibits a variation in the particular waveform as described below. Therefore, when the tension sensor detects a tension change in the particular waveform, the component malfunction detecting means determines that the yarn supplying bobbin has fallen down.
  • the automatic winder is characterized in that when the tension increases in proportion to unwinding of the yarn from the yarn supplying bobbin, the component malfunction detecting section determines that the yarn unwinding assisting device controlling an unwinding balloon from the yarn supplying bobbin is malfunctioning.
  • the yarn unwinding assisting device has the function of inhibiting a possible variation in tension applied to the yarn unwound from the yarn supplying bobbin and a possible increase in tension associated with progression of the unwinding.
  • the component malfunction detecting section can easily determine that the yarn unwinding assisting device is malfunctioning.
  • the present invention provides a method for detecting malfunction in an automatic winder including a winding unit that guides a yarn unwound from a yarn supplying bobbin through a yarn path to a yarn winding device winding the yarn into a package in the yarn winding device to manufacture the package, the method detecting any malfunctioning winding unit component of the automatic winder.
  • the method uses a tension sensor measuring tension of a yarn passing through a yarn path and a tension measured value detected by the tension sensor to detect any of components of the winding unit which is malfunctioning.
  • any of the components provided in the winding unit malfunctions, the tension applied to the yarn passing through the yarn path changes.
  • the tension change resulting from the malfunctioning component varies among the components.
  • any malfunctioning component can be easily detected based on the condition of the change in the tension measured value from the tension sensor.
  • the present invention allows which of the plurality of components provided in the winding unit is malfunctioning to be detected based on the tension measured value from the tension sensor. This enables the malfunctioning to be dealt with immediately after the malfunctioning has occurred. Checking a record of past improper tensions allows estimation of a yarn winding length corresponding to a point in time when the operation on the package has become improper. This enables the improper part of the yarn to be unwound and removed.
