Definitions

  • the present invention relates to a yam setting method and an automatic winder according to the preamble of claim 1 and 9, respectively.
  • a known yam setting method for a winding tube in an automatic winder is such that under the state in which the yarn is connected between the yarn supplying body and a yarn winding body, a doffing device picks up and cuts the connected yarn and traps the lower yarn leading to the yarn supplying body, discharges the yarn winding body, and sets a new winding tube at the same time as the setting of the trapped yarn of the yarn supplying body to the winding tube.
  • the upper yarn trapped by the suction pipe and the lower yarn trapped by the relay pipe are led into a yarn joining device respectively, the yarn is joined.
  • a state in which the yarn is connected from the yarn supplying body to the yarn winding body is created.
  • the position to pick up the lower yarn is located in the lower part of a winding unit and away from the position of the doffing device. Therefore, the accuracy in the position of the yarn picking lever to be advanced from the doffing device to the lower direction is required to be high, and the time required for the yarn picking lever to advance to the lower direction also becomes long.
  • the present invention was made in consideration to aforementioned problems and it is thus the object of the present invention to provide a yarn setting method for the winding tube in an automatic winder and an automatic winder capable of carrying out the setting operation of the yarn of the yarn supplying body smoothly and speedily.
  • the doffing device Since the moving of the lower yarn to the yarn winding body side by the lower yarn trapping-leading member at the winding unit side is completed before the doffing device arrives at the winding unit, the doffing device is capable of starting the picking operation of the lower yarn immediately after arriving at the winding unit, and as a result, the time required for setting the yarn to the winding tube can be shortened.
  • the lower yarn When the yarn winding body becomes full and the yarn is cut, the lower yarn may be held by the holding means temporarily, and then the lower yarn is trapped by the lower yarn trapping-leading member. As a result, the lower yarn can be held by the lower yarn trapping-leading member reliably.
  • a tension applying device for applying tension to the yarn may also serve as a holding means for holding the lower yarn after the yarn is cut. Therefore, a separate suction-typed yarn trap or the like for holding the yarn when the yarn is cut is not required.
  • the lower yarn trapping-leading member may be on standby under the state in which the lower yarn trapping mouth is facing downward at the yam supplying body side of the yarn joining device during winding, and the yarn trapping by the lower yarn trapping-leading member can be carried out speedily after the yarn is cut. Since the yarn held by the holding means is trapped by the lower yarn trapping-leading member being moved from the downward state to the yarn trapping position, a separate movable guide for guiding the yarn held by the holding means to the lower yarn trapping-leading member is not required. As a result, the structure can be simple.
  • the lower yarn trapping-leading member may include a clamp device and be stopped before the leading position for leading into the yarn joining device, the demand signal can be transmitted while the clamp device is under the clamping state, and the yarn of the yarn supplying body is not drawn out excessively.
  • a first driving means may be available exclusive for the lower yarn trapping-leading member, when the yarn winding body becomes full and a doffing is demanded, without operating unnecessary members including the upper yarn trapping-leading member, only the lower yarn trapping-leading member can be operated. Therefore, the trapping of the lower yarn after the yarn is cut and the lifting of the trapped lower yarn to the yarn winding body can be carried out speedily, and the doffing demand can be transmitted in early stage after the yarn winding body becomes full.
  • a stepping motor is used for the first driving means, according to the control pulse number, the lower yarn trapping-leading member can be stopped at any position reliably.
  • the upper yarn trapping-leading member and the yarn joining device may be prohibited, the upper yarn is not drawn out from the yarn winding body and the yarn joining is not carried out, and only the moving of the lower yarn to the yarn winding body side by the lower yarn trapping-leading member is carried out.
  • the yarn winding body is not rotated, and the yarn leading to the yarn winding body is not trapped by the upper yarn trapping-leading member.
  • the yarn joining device is prevented from working on the lower yarn, and in addition, the position where the lower yarn trapping-leading member is stopped, is located immediately in front of the position where the yarn is led to the yarn joining device, and the lower yarn trapping-leading member is capable of transporting up the lower yarn to the highest position.
  • the upper yarn sucking-leading member Only by lifting the yarn winding body from the driving drum by the lifting means, the upper yarn sucking-leading member becomes non-acting, and by the pausing means for the driving means of the upper yarn sucking-leading member and the lower yarn sucking-leading member, the lower yarn is led to a position higher than the yarn joining device by the lower yarn sucking-leading member.
  • the upper yarn trapping-leading member and the lower yarn trapping-leading member can be paused per each winding unit.
