Definitions

  • the present invention relates to a device for controlling a balloon during the unraveling of a bobbin, and to a method for controlling a balloon during the unraveling of a bobbin.
  • industrial-type winders comprise a plurality of mutually independent winding units, operated by a programmable control unit.
  • the winding unit winds a yarn onto a generally cone-shaped support to make a reel that will be used in weaving, knitting, or other next processes.
  • the yarn is wound on the support with a predetermined type of winding to optimize the successive unraveling of the yarn from the reel during the step of weaving.
  • thread or monofilament or continuous filament means a single filament or continuous bave (e.g. in the case of silk, artificial or synthetic fibers), while the term yarn means the set of fibrils of variable length which are parallelized and joined by twisting.
  • thread or monofilament or continuous filament means a single filament or continuous bave (e.g. in the case of silk, artificial or synthetic fibers)
  • yarn means the set of fibrils of variable length which are parallelized and joined by twisting.
  • the winding is preferably carried out with a cylinder in contact with the reel and rotating around an axis which is substantially parallel to that of the reel, arranged with a particular geometry of seats made on its surface.
  • the yarn near the bobbin forms a so-called balloon; the yarn in its unwinding movement from the bobbin widens with respect to the shape of the yarn wound on the bobbin, and such widening extends for a given height above the bobbin.
  • a correlation between balloon diameter and unwinding tension is known; in particular, it is known that as the unwinding speed of the bobbin increases, the diameter of the balloon increases, and consequently so does the unwinding tension.
  • US 2017/130369A1 discloses a two-for-one twisting or cabling machine which comprises an adjustable balloon-yarn-guide-eye.
  • the containment element is part of a device known in technical jargon as a "balloon breaker", which comprises other components according to the functions associated with the device itself.
  • the movement is performed through a drive connected to a screw element parallel to the direction of movement of the containment element, exploiting the movement of a so-called spiral screw coupling.
  • the device further comprises sensors, e.g. optical sensors, adapted to detect the height of the portion of bobbin covered with yarn and transmit such information to a programmable control unit, which consequently controls the drive to lower the containment element.
  • sensors e.g. optical sensors, adapted to detect the height of the portion of bobbin covered with yarn and transmit such information to a programmable control unit, which consequently controls the drive to lower the containment element.
  • the system is highly complex because it requires continuous monitoring of the winding state of the yarn on the bobbin to be able to move the containment element continuously.
  • the high number of required components also affects the number of parts that could potentially have problems, or which in any case need to be subjected to routine and supplementary maintenance.
  • the device 12 for controlling the balloon comprises a containment element 15 adapted to contain at least partially in a through opening 18 thereof the balloon of the yarn 14.
  • the device 12 comprises a support 20 adapted for supporting the containment element 15 and adapted to be fixed to a structure of a winding unit.
  • the device 12 further comprises movement means 22 arranged between the containment element 15 and the support 20, adapted to move the containment element 15, during the unraveling of the yarn 14 from the bobbin 16, between a rest position, and an extracted position.
  • the device comprises a programmable control unit connected to the movement means 22.
  • the movement means 22 are adapted to move the containment element 15 from the rest position to the extracted position, based on at least one operating parameter set on the programmable control unit.
  • Figure 1 schematically shows the device 12 in a first configuration with containment element 15 in the rest position.
  • Figure 2 schematically shows the device 12 in a second configuration with containment element 15 in the extracted position.
  • the device 12 according to the present invention may comprise a second containment element 19 fixed with respect to the supporting structure 20.
  • the second containment element 19 may be aligned with the containment element 15.
  • the at least one predetermined operating parameter may comprise the yarn thread count and/or the winding speed and/or processing time.
  • the at least one predefined operating parameter may comprise yarn tension.
  • the movement means 22 may comprise a linear actuator 24, which is schematically shown in figures 1 and 2 .
  • the linear actuator may be a pneumatic or hydraulic actuator.
  • the direction of movement can be substantially parallel to the direction of an axis X of a bobbin during unraveling.
  • the direction of movement can be substantially vertical with respect to the supporting surface of the machine.
  • the movement means 22 may only allow two operating positions, in particular the rest position, in which the containment element 15 is close to the support 15, and an extracted position, in which the containment element is spaced from the support 20 with respect to the previous position.
  • operating position means a position that can be maintained while processing for a given processing time, e.g. longer than 5 seconds.
  • the movement means according to the present invention may allow a discrete positioning of the containment element 15 with respect to the support 20.
  • the distance between the rest position and the extracted position of the containment element 15 may be greater than 50 mm. In particular, the distance between the rest position and the extracted position of the containment element 15 may be between 60 mm and 100 mm.
  • the predetermined operational parameter through which the programmable control unit controls the movement equipment is a processing time.
  • the programmable control unit may be adapted to require the movement of the containment element 15 when a given processing time is reached.
  • the preset operating parameter is the yarn count, and a percentage of yarn unwound from the bobbin.
  • the operator can enter the two parameters in the programmable control unit which, together with the winding speed, will allow the programmable control unit to establish the percentage of yarn unwound from the bobbin and thus the consequent activation of the movement means.
  • the percentage of yarn unwound from the bobbin can be set to be between 40 and 50%.
  • the at least one predetermined operating parameter may be the yarn tension.
  • the programmable control unit can be adapted to enter the yarn tension value at which activate the movement means 22.
  • the balloon control device 12 may comprise at least one sensor adapted to detect the tension value reached by the yarn and to transmit such value to the programmable control unit to compare it with the value set by the operator.
  • the device 12 for controlling the balloon during the unraveling of yarn from a bobbin may allow a discrete positioning of the containment element 15 with respect to the support and, in particular, with respect to the bobbin.
  • the devices of the prior art allow a continuous movement of the containment device as the unwinding progress state changes. Such continuous movement, on the one hand, optimizes the containment of the balloon, but on the other hand, has a heavy impact on the cost of the machine and its complexity.
  • the movement means may comprise an electric actuator.
  • the electric actuator may allow a continuous movement between the rest position and the extracted position.
  • the balloon is controlled without the presence of sensors which must be managed by a programmable control unit which can be very complex.
  • the programmable control unit may, for example, be a simple timer, adapted to control the movement means when a given processing time is reached.
  • the method substantially comprises the steps of:
  • the predetermined operating parameter may be the yarn thread count and/or the winding speed and/or a processing time.
  • the predetermined operating parameter can be the yarn tension.
  • the method makes it possible to obtain efficient balloon control during the unraveling of a bobbin in a winding unit of a winder without using information received from sensors.
  • the method makes it possible to use simple linear actuators that allow discrete positioning of the containment element.
