Definitions

  • the invention relates to a method of damping vibrations of a yarn winding device for winding yarn on a bobbin of a textile machine, in which vibrations are damped by a magnetic force acting between a permanent magnet on a winding arm and a magnetically adhesive body associated with the winding arm, whereby the permanent magnet moves on the magnetically adhesive body.
  • the invention also relates to a device for damping vibrations of a yarn winding device for winding yarn on a bobbin of a textile machine, which comprises a permanent magnet mounted on a winding arm of the winding device, whereby a magnetically adhesive body is associated with the path of the magnet, the permanent magnet being adapted to move along the magnetically adhesive body.
  • the invention relates to a textile machine comprising at least one yarn winding device on a bobbin.
  • a variety of bobbin vibration damper solutions are known for machines producing or processing textile yarns.
  • document EP2949612 discloses a winding device having a vibration absorber with an absorber mass and with an associated elastic element which also constitutes a damping element which is made of plastic.
  • CZ 149 992 discloses a mechanical damper, especially for a spindleless spinning machine, which comprises a swinging rod mounted in a body with two friction elements with different coefficients of friction.
  • a similar solution based on a mechanical principle is also described in CN 102 586 962 .
  • Another well-known principle is a solution using a permanent magnet or electromagnet in interaction with a magnetizable adhesive segment, e.g., according to CH 430527 A and DE 1973332 U , in which the contact pressure between the winding bobbin and the friction drive of the bobbin is briefly increased during the winding of the yarn by means of a magnet, the magnet being heightadjustable.
  • electromagnet for vibration damping is also described in CH 374 003 , wherein the electromagnet acts on a plate which is attached to a bobbin support frame, wherein an adjustable control resistor is adapted to control the electric current supplying this electromagnet so that it is possible to adapt the force effect of the magnetic field to the desired damping of the bobbin.
  • DE 1830734 U discloses a guideway for damping vibrations of a bobbin during the process of winding yarn, which consists of a magnetizable adhesive plate, preferably in the shape of a crescent, mounted at a workstation parallel or approximately parallel to the path of movement of a swinging arm holding the bobbin.
  • a permanent magnet or electromagnet which is arranged on the side of the swinging arm or on a counterweight placed on it, slides over the adhesive plate during operation.
  • the magnetizable adhesive plate of the guideway is designed to be flexible and the magnet housing is fixedly mounted on the winding frame.
  • DE 2606859 A1 discloses a winding device of a textile machine, which comprises a winding frame 3 which is rotatably mounted on a frame 1 of the machine by means of a horizontal rotational pivot 2. At its free end, the winding frame 3 carries a bobbin 4 which is placed on a driven friction drum 5 through which the bobbin 4 is driven and a yarn thread 6 is wound on it.
  • the winding frame 3 forms an upward bend in the vicinity of the horizontal pivot 2.
  • a horizontal opening 7 is formed in the frame 3 in which a cylindrical pin 8, which is also horizontal, is elastically and loosely fixed.
  • the pin 8 is elastically and loosely seated in the horizontal opening 7 by means of a pair of rubber rings 9 which fit into circular grooves at the ends of the pin 8.
  • the annular gap formed between the opening 7 and the pin 8 by radial clearance is closed at both ends by these rubber rings 9 and is filled with oil or grease 10.
  • One end 11 of the pin 8 protrudes from the opening 7 and has a surface in the form of a spherical cross-section, the centre of which lies in the axis of the pin 8. This end 11 lies without radial clearance in the hole of a disc 12.
  • this disc 12 On the side facing away from the winding frame 3, this disc 12 has a recess which is concentric with the central axis of the pin 8 and an annular permanent magnet 13 is mounted on this recess.
  • the annular permanent magnet 13 rests with its front surface 14 on the machine frame 1 and is made of steel or another magnetizable material.
  • the permanent magnet 13 causes its surface 14 to rest with a certain force on the surface 15 of a sheet 16.
  • the disc 12 can thus move freely with respect to the end 11 of the pin 8 in the direction of its axis, i.e., perpendicular to the surface 15.
  • the winding frame 3 slowly rotates upwards around the pivot 2 and the permanent magnet 13 slides onto the surface 15 of the sheet 16.
  • the frictional force between the surfaces 14 and 15 puts up practically no resistance to this movement, but the force of the permanent magnet 13 is selected so that the frictional force between the surfaces 14 and 15 is sufficient to prevent the disc 12 and pin 8 from contributing to the oscillation of the winding frame 3 around the hinge pivot 2.
  • the opening 7 of the winding frame 3 moves outside the centre of the pin 8, which is made possible by the elasticity of the rubber rings 9.
  • the annular gap between the opening 7 and the pin 8 is reduced on one side and widened on the opposite side. Therefore, part of the oil or lubricant 10 in the annular gap is displaced into the gap by compression. This results in effective vibration damping.
  • the disc 12 is not provided with a magnet but is pressed against the counter sheet 16 by a spring. Due to the spherical cross-section of the end 11 of the pin 8, it can be easily inclined towards the disc 12 and the sheet 16, so that mounting inaccuracies are eliminated.
  • the disadvantage of this arrangement is the additional movement of the magnet with three degrees of freedom with respect to the tilting plane of the winding arms, i.e., not only the tilting of the magnet around the spherical end 11 of the pin 8, but also the linear movement of the magnet in the direction of the longitudinal axis of the pin 8, which is 3 degrees of freedom (2 rotations + one linear movement).
  • the pin 8 it is therefore necessary for the pin 8 to be resiliently mounted in the opening 7 in the arm by means of a pair of spring rings 9 and for the free space between the pin 8 and the opening 7 in the arm 3 to be filled with oil or grease, which is complex, reduces the durability of bearings and connections and increases the risk of failure and transmission of vibrations with all the disadvantages.
  • the damping of the vibrations does not occur by small movements of the magnet on the sheet 1 but occurs on the rings 9 and oil or grease in the resilient bearing of the pin 8 in the opening 7.
  • the objective of the invention is to eliminate or at least minimize or at least reduce the disadvantages of the background art while maintaining simple construction of the system for damping bobbin vibrations and the winding device during the winding of the yarn onto a bobbin, without the need to supply energy into this system for damping vibrations.
  • the objective of the invention is achieved by providing a movable connection between a winding arm and a housing of a permanent magnet, thus achieving a better position of the permanent magnet relative to a magnetizable adhesive plate.
  • This connection can preferably be implemented, for example, by a ball joint or a resilient member. Due to the ball joint or elastic element, the correct position relative to each other is established automatically, the permanent magnet is always at a defined distance from the magnetizable adhesive plate, without the risk of collision between the magnet housing and the adhesive plate.
  • the use of a ball joint or resilient member will allow the arms to be opened to remove the bobbin when skidding and to insert an empty tube. At the same time, this solution allows adjustment of the winding arms for winding both a cylindrical bobbin and a conical bobbin.
  • the advantage of the invention is easy and automatic adjustment of the ideal mutual position of the permanent magnet and of the magnetically adhesive body and long-term sustainability of this ideal mutual position, all even when moving away (opening) the winding arms to replace the full bobbin for an empty tube as well as when adjusting the winding device for winding a cylindrical bobbin or a conical bobbin.
  • the invention will be described with reference to an exemplary embodiment of a workstation of an air-jet spinning machine for producing yarn, however, the invention is applicable to a winding device of another type of a textile machine, e.g., a rotor spinning machine, a rewinding machine, etc., without exerting inventive effort and within the knowledge and skills of a person skilled in the art.
