Definitions

  • the invention relates to a method of spindle spinning or twisting, at which the yarn or thread is wound on a cylindric tube, which is mounted on rotating spindle, while the yarn or thread is wound into a package in the form of a cop, during the winding is the balloon limited by rotating balloon limiter, whose inner surface serves for contact with yarn or thread.
  • the invention relates to a device for spindle spinning or twisting by a method according to the invention comprising frame, on which is mounted the spindle rail, on which there are rotatably mounted spindles for mounting the tubes for winding of the cop, whereas each spindle is coupled with a drive.
  • PV 2003-588 discloses device for loop spinning or twisting, that comprises a vertical spindle and with it axially arranged balloon limiter for feeding the yarn to a tube on rotating spindle.
  • the balloon limiter consists of rotatably mounted and in the same sense as the spindle driven upper part and to it, in a contactless manner, continuing non-rotating lower part.
  • the lower part has a guiding surface for the yarn, which begins on its inner side and finishes on its lower face side.
  • the balloon limiter is encircled with a static cover of a cylindric shape.
  • the cover of package serves to reduce the noise level and to maintain a high quality of textile product through continuous cleaning of the spinning space.
  • the cover of package prevents a strong ventilation during the technological process.
  • the ventilation is efficiently directed into a closed space in vicinity of rotating spindle, whereas the cover of package prevents a free exchange of air with surroundings. Through this a suction of static air from surroundings into area of spindle, its acceleration and subsequent tangential blowing-off into surroundings is prevented.
  • Solution according to DE 19702678 discloses a cover of package on a ring spinning machine.
  • the ring rail On its lower surface the ring rail carries the stationary tubes serving as covers for yarn package being created on tubes of spindles.
  • the tubular covers gradually slip over the created packages and for the most part they cover them, at least in area of the greatest diameter.
  • the spinning process itself is running in area above the cover of package in relatively great distance from the cover.
  • Modern textile machines are further equipped with covers of package, which besides their basic function offer a possibility to clean continuously the space in vicinity of technological production process and reduce the noise produced at fast motion of rotating members and at fast streaming of air.
  • these covers are attached on a spindle rail.
  • the covers may be of a stable size, or they are adjusting to a changing size of space being filled during distribution of the yarn on package.
  • DE 19548664 discloses a cover of rotating body of centrifuge serving for closing the space between external environment and rotating casing of the centrifuge. This space is sealed and at centrifuge running the air pressure is reduced inside it, by which air turbulence between the fixed and rotating wall is limited, thus ventilation losses at high speeds of centrifuge are reduced.
  • DE 10 2004 029 207 describes winding of the package in direction from bottom of the tube to the top of the tube, while upper part of the tube is without package and is inserted into the limiter of the balloon and the limiter gradually exposing the free part of the tube for winding next part of the cop. Only in fig. 4 there is showed stationary capsule 10 covering lower part of the tube with the package while the balloon limiter is still covering upper part of the tube. DE 10 2004 029 207 does not show any solution for winding from the top of the tube to the bottom of the tube with rotating cover of the package being gradually inserted into the cover during the winding.
  • the known solutions are structurally complicated, expensive and the covers of package do not reach the immediate proximity of spinning or twisting zones, by which their technological efficiency especially in the sphere of ventilation losses is reduced, hence reduction of noise and power consumption is insufficient.
  • the goal of this invention is to remedy these shortcomings or to reduce them at maximum.
  • the goal of the invention has been achieved through a method according to claim 1.
  • the cover of package can be positioned in a close vicinity of spinning area, thus reduce the ventilation losses.
  • cover of package is formed of a means, whose inner surface is in contact with the processed material, e.g. of the yarn carrier, balloon limiter, cap, etc.
  • FIG. 1 shows axonometric view to operating unit
  • the Fig. 2 axonometric view to operating unit in embodiment with drive of balloon limiter or of the cap by means of a belt
  • the Fig. 3 a section through the operating unit in embodiment according to the Fig. 1 at a time when package of the cop is being completed
  • the Fig. 4 shows a section of the operating unit according to the Fig. 1 after starting during the course of cop winding.
  • the spindle spinning or twisting machine comprises a number of operating sites, which are arranged side by side usually on both sides of the machine.
  • Each operating site comprises the operating unit and unwinding site of the processed fibre formation 2 , for example of roving, yarn or thread, between which there is arranged the feeding mechanism 3 of fibre formation 2 , for example at the spindle spinning machines formed of a known drafting mechanism, out of which the delivery rollers are represented in the figures.
  • Each operating unit comprises the spindle 6 which is in a known manner by means of spindle bearing 9 mounted on the spindle rail 5 , which is in a known not represented manner coupled with the not represented drive enabling its reverse motion in vertical direction necessary for creating package of the cop.
  • the spindle 6 In the lower part the spindle 6 is provided with belt pulley 12, which is by means of a belt coupled with known not represented drive which secures rotation of the spindle 6 .
  • the spindle 6 In the upper part the spindle 6 is provided with cylindrical mandrel 10, on which during operation of the operating unit of the machine there is installed the tube 7 serving for winding of the produced yarn or thread.
  • the tube 7 is fixed on the spindle 6 by means of fixation means 11 , for example by a short cone on lower part of the mandrel 10 or in other known manner.
  • a carrier 13 of yarn or of thread or a cap or other body with cylindric inner surface or a balloon limiter according to the type of technology of spindle spinning or twisting.
  • These means in this invention create a rotating cover of package, while inner diameter of their cavity is greater than the maximum diameter of package and length of the cavity equals at least to height of package and upper part of the tube.
  • the yarn carrier 13 is encircled by the static cover 20, which is firmly mounted on frame 1 of the machine.
  • the carrier 13 of yarn or of thread or the cap or the balloon limiter are in the upper part provided with hollow cylindric body 15, which is in a known manner mounted in a not represented bearing.
  • the guide eye 4 serving for shaping of track of the yarn P and for limiting of its amplitude.
  • Drive of the carrier 13 of yarn or of thread or the cap or the balloon limiter may be secured by some of the known methods, for example by individual drive or by means of driving belt pulley 16 arranged above the bearing, as it is shown in the Fig. 2 , or by a direct drive from the spindle by means of magnetic coupling 17.
  • the magnetic coupling 17 is formed of the driving components 18 arranged in upper part of the spindle 6 and of driven components 19 arranged on the carrier 13 of yarn or of thread or on the cap or on the balloon limiter. Magnetic coupling 17 ensures synchronous rotational linkage between the spindle 6 and the carrier 13 of yarn or of thread or the cap or balloon limiter.
  • the device according to the invention may be applied also on the ring spinning or twisting machines.
  • the processed fibre formation 2 is fed through the feeding mechanism 3 into the guide eye 4, from which it is directed into the cavity of the cylindric body 15 of the carrier 13 of yarn or of thread or into the cap or into the balloon limiter and it further passes through these means and touches their inner wall, through which it is according to the used technology for imparting the twist either twisted or only guided on this inner wall.
  • Winding of yarn or thread on the tube is started in the upper part of the tube 7 , and in a known motion of the spindle rail 5 the package 8 in a shape of cop is created.
  • the package 8 is created in direction from top of the tube 7 to its bottom by reversible motions of the spindle rail 5.
  • the already completed section of the package 8 gradually inserts into the rotating cover of package, which in exemplary embodiment according to the Fig. 3 is formed of the carrier 13 of yarn.
  • the package may be also created in the same procedure, i.e. in direction from the top of the tube 7 to its bottom, but by reversible motions of the carrier 13 of yarn or of thread or the cap or the balloon limiter, on presumption that the spindle rail is not moving in vertical direction.
  • the cover of package may be stationary. Nevertheless generally it is better, if the cover of package is rotatable and rotates in the same direction as the spindle. At the same time at high speeds of spindles it is advantageous, if the cover of package rotates at the same speed as the spindle.
  • the invention is designated for cotton and wool preparation plants and spinning mills of textile industry.
