Description
Technical field
The present invention relates to a kind of fine spining machine yarn twisting break detecting method, belong to textile machine ring throstle Yarn break detection technique field.
Background technology
In the system yarn process of fine spining machine; Rove is got into drafter from hanging to split to deliver to after leading the reed horn mouth; Under the negative-pressure air-flow effect, on the air-flow guide groove, gathered when making the fiber strip filoplume in gathering pipe through the pneumatic apparatus for collecting in the drafter, reached the requirement that reduces Yarn filoplume and the brute force that increases yarn along with the grid ring rotational conveyance; Yarn after gathering gets into steel traveler twisting through twizzle, and is shaped on the reel for yarn winding reel after will twisting.
In the twisting process of spun yarn, the yarn of the front roller of drafter output is through being installed in the twizzle on the guide plate, again through being arranged on the steel traveler on the rings; In the rotation process of stator with yarn around to the bobbin that tightly is placed in spindle; During the spindle revolution,, steel traveler is turned round along rings by affecting of yarn tension; Steel traveler drives yarn and returns along rings that yarn just obtains a turn when going around; And be installed on the ring rail rings as the rotating track of steel traveler, in twisting process yarn in tow steel traveler on rings, make high speed rotary, in action of centrifugal force; The inner arc that makes the interior pin of steel traveler be close to rings is to slide on the inner track; Usually the speed of gyration of steel traveler on the rings runway can reach about 30m/s～55m/s, and behind the Yarn break of one of them position of splitting, this steel traveler that splits the position can not normally turn round.Twist the Yarn break detection of a side at present for fine spining machine; The touring detection mode that moves of a kind of employing; Be to establish in the ring rail front side runway is installed, a magnetoelectric transducer is installed on the runway, induce the turn signal of a steel traveler that respectively splits through the magnetoelectric transducer that moves; And through lead with signal in central processing unit, to detect each ingot position spinning broken end situation.But owing to need runway to be mounted in the front portion of ring rail; And the existence of runway all drives inconvenience for manually-operated and cleaning; Especially a magnetoelectric transducer detects the steel traveler of each ingot position in moving process; Owing to up to a hundred spindles are installed on the locomotive, so magnetoelectric transducer can not in time be found the ingot position of Yarn break and send the broken yarn signal.Also has a kind of device that each ingot position Yarn break is detected at present for this reason; On the position of the heat that rubbed when adopting temperature sensor to be installed in the fine spining machine spinning; Soon temperature sensor is directly installed on the then interior of ring rail or withstands on the rings wall through spring, directly detects the difference variation of rings friction temperature through temperature sensor and judges Yarn break.Though this structure can solve timely Yarn break to every ingot position and detect, and can not influence operation and cleaning.But rely on the detection rings temperature difference can not judge accurately whether yarn broken end occurs; Because when spindle drove the steel traveler revolution in when revolution, rings can receive the impulsive force of steel traveler, and the size of this impulsive force is tens times of summation of all other power that rings bears; So make rings and steel traveler quicken decline; Because rings is in an operation cycle process, the friction temperature of rings is not a definite value, and involving of fine spining machine is different with the yarn variety of twisting; Therefore the requirement of yarn twist coefficient is different, therefore adopts the rings temperature difference to judge that the accuracy rate of Yarn break is not high.In addition, because in spinning process, though fine spining machine is provided with dust collection mechanism, the some fibre that still can float in the air, and work as fiber-covered on temperature sensor, also can reduce accuracy of detection.
