Abstract
The invention discloses a control method for yarn tension of a straight twisting machine, and belongs to the technical field of textile machinery. The problems that external yarn tension control is not accurate, and an optimum ballooning shape cannot be reached exist in the existing straight twisting machine. The straight twisting machine is characterized in that a strand yarn sensor is arranged in a yarn path between an overfeeding device and an even twisting device and used for detecting a strand yarn linear speed and tension; a motor sensor is arranged on a spindle drive motor and used for detecting a motor speed and motor current; an external yarn tensioner is driven by a separate motor to feed yarns actively; an overfeeding wheel of the overfeeding device is driven by a separate motor; and by taking one or two detection results of the two sensors as separate or combined control parameters, a control system controls a speed of the motor connected with the overfeeding wheel, adjusts a strand yarn pulling speed, and ensures that an external yarn tension value meets a requirement of the optimum yarn ballooning shape capable of allowing a wrapping angle to be minimum.
Description
Technical field
The invention belongs to technical field of textile machine, especially relevant with the straight twister method for controlling yarn tension produced of energy energy efficient, reduction noise.
Background technology
Straight twister is that a kind of being mainly used in directly also synthesized a strand yarn with two strands of yarns, adds to be twisted cord fabric thread, and is wound into the textile machine of parallel cheese.And close when twisting, two strands of yarns are introduced from two yarn packages respectively, one of them yarn package is placed in the spindle of rotation, another strand yarn passes outside spindle in the twisting plate of spindle and passes through, then two strands of yarns and close and enter uniform twister, formed interior yarn and outer yarn, outer yarn can form air ring in the spindle rotary course.Before yarn is incorporated into air ring from twisting plate, the at least part of looping of outer yarn is on twisting plate, energy consumption and noise that the size impact at the looping angle that forms due to looping is twisted thread, the looping angle is larger, energy consumption and noise are larger, and the form of air ring (being mainly the air ring diameter) directly affects the size at looping angle.Existing straight twister is controlled outer yarn tension by hysteresis brake and is realized minimum air ring diameter, reduces the looping angle.Because outer yarn yarn road is long, outer yarn tension is controlled inaccuracy, and it is best that balloon shape can't reach, and is difficult to reach energy-conservation to greatest extent.
Summary of the invention
Purpose of the present invention is intended to solve the problem that the outer yarn tension control of existing straight twister employing hysteresis brake formula can not accurately be controlled, balloon shape can't reach the best, provides the straight twister method for controlling yarn tension produced, effectively energy efficient, reduction noise.
for this reason, the present invention is by the following technical solutions: a kind of straight twister method for controlling yarn tension produced, straight twister comprises rack-mounted spindle, the spindle drive motors, uniform twister, super-feeding device and batching apparatus, on the outer yarn yarn road of spindle twisting plate upstream, outer yarn tensioner is set, on the interior yarn yarn road of spindle and uniform twister, interior yarn tensioner is set, it is characterized in that: outer yarn tensioner is by the initiatively line sending of independent motor-driven, the overfeeding wheel of super-feeding device is by independent motor-driven, any one or two that strand yarn sensor detects in strand yarn speed and burst two parameters of yarn tension are set on the thigh yarn yarn road between described super-feeding device and uniform twister to be detected simultaneously, control system is take the testing result of thigh yarn sensor as controlling parameter, controlling the motor speed that is connected with the overfeeding wheel changes, regulate a burst yarn hauling speed, make the tension value of outer yarn satisfy outer yarn air ring optimal morphology, should outer yarn air ring optimal morphology be exactly to make the looping angle minimum of outer yarn on twisting plate.
As to technique scheme replenish and perfect, the present invention can also adopt following methods.
On the basis that strand yarn sensor is set, any one or two that electromechanical transducer detects in motor speed and two parameters of current of electric are set on described spindle drive motors simultaneously detect simultaneously, described control system is connected testing result with the testing result of thigh yarn sensor and is arbitrarily made with at least two and controls parameters and control the motor speed change that is connected with the overfeeding wheel with electromechanical transducer.
Described outer yarn tensioner is by initiatively line sending of independent motor-driven uniform rotation.
The motor that described outer yarn tensioner connects rotates initiatively line sending take spindle drive motors rotating speed, current of electric, strand yarn speed, strand yarn tension as controlling parameter control speed change by control system.
Use the present invention can reach following beneficial effect: by detecting a strand yarn speed, strand yarn tension, spindle drive motors rotating speed, current of electric and controlling to adjust a burst yarn hauling speed as controlling parameter, outer yarn air ring is reached to make the optimal morphology of the looping angle minimum of outer yarn on twisting plate, save energy consumption, reduced noise.
