Definitions

  • the present invention is concerned with a method of winding yarn, in which the yarn breakage is removed without interrupting the winding process, and with a device for performing said method.
  • An automatic winding machine in which yarn breakage is removed while running, i.e. without interrupting the winding process. in this machine a knotter is being used, which can form a knot within sec., i.e. that in view of this time interval at a winding speed of 1,000 meters per min. 8 ems. of yarn are wound on to the bobbin.
  • the yarn achieves between the delivery cop and the bobbin built a velocity which is determined by a driving member, usually in the form of a winding drum, driving frictionally the bobbin being built.
  • the method according to the present invention aims at overcoming said drawbacks, i.e. at removing a yarn breakage without interrupting the winding process, at high speed, by using a simple, reliable and unexpensive knotter, said knotter working at a considerable lower speed, from about sec. to several seconds.
  • the method according to the present invention is characterized in that the yarn is accumulated on its path between the knotter and the bobbin being wound, in order to form a reserve, so that the speed of said yarn suddenly drops to a value near zero or even zero.
  • said yarn is wound off from said reserve, while the end of the new yarn is knotted to the yarn end from said reserve. Then the reserve is completed to the value necessary for further knotting, this being done at a higher speed than the usual winding speed.
  • the main feature of the device for performing the method accord- Claims ing to the present invention is the element for accumulating a yarn reserve, said element being placed within the yarn path between the knotters and the winding mechanisms, as well as means for drawing off yarn from cops and delivering said yarn .into said element.
  • FIG. 1 is a diagrammatic, sectional view of an embodiment in which the yarn reserve is formed by pneumatic means.
  • FIG. 2 is a diagrammatic, sectional side view of an embodiment with a roller for increasing the take-up speed of said pneumatic means.
  • FIG. 3 is a diagrammatic, sectional side view of an embodiment in which the yarn reserve is formed mechanicall
  • the same elements have the same reference numbers in all figures.
  • Yam 1 is drawn oif cop 2 and passes through an eyelet 3, an auxiliary brake 4, an electronic clearer 5 or a mechanical clearer 6 and a sensor 7, and from there into the knotter '8 and towards the means for drawing off the yarn.
  • these means are formed by a pneumatic nozzle 9 of the penumatic mechanism 10, one part of which is formed by a pressure medium source( not shown), said nozzle passing into the element for accumulating the reserve, i.e. in the present case into a vessel provided with openings, e.g. a perforated vessel 11, said vessel being slightly increased in width towards the bottom.
  • This vessel can be also made in form of a wire cage, so that the air leaving nozzle 9 can escape through the openings of the perforated vessel or through the cage, if said vessels are not filled up by the yarn reserve.
  • the bottom of the perforated vessel 11 is provided with the opening 12, through which the yarn is drawn off, and fed to the bobbin 14 for being wound up, said yarn passing on its way to said bobbin through a brake 13.
  • Bobbin 14, which can have any shape is driven e.g. directly by the winding drum 15.
  • the pneumatic mechanism is equipped with a valve 16, said valve being situated in the supply of nozzle 9 and controlled either by the knotter 8 and the sensor 7 or by th electronic clearer eg by means of the electromagnet 17.
  • a cutting mechanism 18 and a gripper 19 are situated below the knotter, in the yarn path a cutting mechanism 18 and a gripper 19 are situated for cutting and gripping the yarn in case of a slub, so as to keep the yarn tensioned or, to hold in case of yarn breakage the upper end of the yarn.
  • nozzle 9 begins to draw otf yarn 1 from cop 2 and store it in the perforated vessel 11, i.e. said nozzle begins to form the reserve. This is done for such a time, during which the air can still escape through the openings of perforated vessel 11. As soon as said vessel is filled up with yarn, said yarn closes all openings of the perforated vessel 11 and because of that the air stops flowing through nozzle 9, the drawing-off of yarn being thereby stopped.
  • an impulse of knotter 8 opens valve 16, nozzle 9 completing now at an increased drawing ofi speed the yarn reserve in the perforated vessel 11, whereby gain the equilibrium state is achieved.
  • FIG. 2 the device according to the present invention is shown, said device being able to induce higher drawing-off forces in yarn 1, and being therefore suitable for processing heavier yarns.
  • a front of nozzle 9 a
  • roller is situated in the yarn path.
  • Yarn 1 is guided over a driven roller 20, the peripheral speed of which is higher than the winding speed, and over an auxiliary roller 21, said yarn being wound around the said rollers once or several times in such a way, as to increase in a known way the traction in the yarn, whereby even heavier yarn can be processed at smaller consumption of air nozzle 9.
  • the roller need not be stopped, as the yarn slips on said roller.
  • FIG. 3 another model according to the present invention is shown.
  • no pneumatic means are used, but mechanical means in form of feeding rollers 22 and 23, at least one of which being driven by the electric motor 24, the peripheral speed of said rollers being higher than the winding speed of bobbin 14.
  • the element for accumulating the yarn reserve is formed by an inclined vessel 25, said vessel being of cylindrical shape and its lower inlet part being arranged on the delivery side of feeding rollers 22 and 23.
  • the bottom 26 of this vessel 25 is provided with an opening 27 for yarn delivery, said bottom having the shape of a piston, which is placed freely traversable in the vessel 25 and, when vessel 25 is empty, the bot-tom 26 bears by influence of gravity-in other models this can be caused by influence of a spring-against a shoulder 28 of vessel 25.
  • the control circuit 29, controlling the electric motor 24, two switches 30 and 31 are connected in series, switch 30 being situated near the upper part of vessel 25 in such a way, that it is switched off by bottom 26, when said bottom is partially shifted out of vessel 25, i.e. in the case of full reserve.
  • the other switch 31 senses the presence of yarn below the knotter 8 and opens the circuit 29 in the case of breakage of yarn 1.
  • yarn 1 is threaded through the gap between feeding rollers 22 and 23 and through opening 27 of bottom 26 and afterwards the electric motor 24 is started.
  • the feeding rollers 22 and 23 convey the yarn into vessel 25 for such a time, until bottom 26 opens circuit 29 of the electric motor 24 by means of switch 30, this being caused by influence of the pressure of the yarn reserve being formed.
  • switch 30 starts electric motor 24 and the feeding rollers 22 and 23 complete the yarn reserve again at a higher speed than the winding speed.
  • switch 31 switches off the electric motor 24 even in the case vessel 25 is not filled up completely so that the end of yarn 1 can be gripped by gripper 19 (not shown in FIG. 3) and the knotter 8 can be brought into action.
  • the circuit 29 is closed after knotting by a switch 33 controlled by the knotter 8, so that the completion of the yarn reserve can be carried on.
  • a method of winding yarn and knotting the same during breakage without interrupting the winding process comprising the steps of guiding the yarn along a predetermined path; winding up the yarn at one end of the path with a predetermined winding speed; I QV P the yarn upstream of said one end with a speed higher than said predetermined winding speed into a vessel until a predetermined yarn reserve is accumulated in said vessel upstream of said one end; and knotting said yarn in case of breakage between said yarn reserve and the other end of said yarn while continuing winding said yarn from said yarn reserve in said vessel.
  • An arrangement for winding yarn and knotting the same during breakage without interruption of the winding process comprising, in combination, guide means for guiding a yarn along a predetermined path; winding means for winding otf the yarn at one end of said path; drive means cooperating with said winding means for rotating the same with a predetermined speed; knotting means along said path for knotting the yarn when broken; a vessel arranged along said path between said knottting means and said winding means, said vessel having an inlet opening through which said yarn enters said vessel and an outlet opening through which said yarn leaves said vessel; and feeding means cooperating with said yarn for feeding the same into said inlet opening of said vessel with a speed greater than that at which the yarn is withdrawn through said out-let opening by said winding means until said vessel is substantially filled with a loose yarn reserve, whereby in case of yarn breakage said knotting means may knot the broken yarn while the winding means continue to wind up yarn from said yarn reserve.
  • feeding means are in the form of pneumatic means including a nozzle extending through said inlet opening into said vessel.
  • said feeding means comprise a pair of rollers engaging said yarn, and drive means connected to at least one of said rollers for driving the same at a peripheral speed greater than said winding speed.
