Pass through from region between 26 light-path of infrared transmitter 25 and infrared remote receiver, the signal that infrared transmitter 25 issues is by yarn 8
Blocked, infrared remote receiver 26 can not receive signal, only when 8 tension of yarn increase, yarn 8 hang down arc reduce situation when, it is red
Outer receiver 26 receives the signal issued from infrared transmitter 25 due to not sheltering from signal by yarn 8, realizes
Detection and judgement to 8 tension of yarn, at this moment, electric controller E accelerate 23 revolving speed of conducting bar roller by third motor, remain normal
Vertical arc, that is, maintain normal tension.
Yarn autoleveller method is carried out using above-mentioned yarn independence evereven, preferably includes following steps:
(1) it inputs in the operation interface 27 of the electric controller E to neat and well spaced 8 technique predefined parameter of yarn, the parameter includes
8 Spinning Varieties of yarn, spinning number, fibre length, line density, volume etc., the electric controller E are pre- according to the technique of yarn 8
Between determining between the moulding pressure value and upper rear roller 1 and upper front roller 4 of the upper rear roller 1 of parameter automatic adjustment, upper front roller 4
Gauge from；In this step, electric controller E automatically adjusts upper rear roller 1, sieve of going forward according to 8 line density of yarn or volume parameter
4 moulding pressure value is drawn, the moulding pressure value is directly proportional to line density or volume size；Electric controller E is according to 8 fiber of yarn
Length parameter automatically adjusts the spacing distance between upper rear roller 1 and upper front roller 4, makes between rear roller 1 and upper front roller 4
Spacing distance be slightly larger than or be equal to fibre length；
(2) the electric controller E control Ru Tiao testing agency A carries out the line density of fixed length to yarn 8 and/or volume detects, and
It will test data and be transferred to electric controller E, the 8 fixed length line density of yarn and/or volume data and work that electric controller E will test
The scheduled line density of skill and/or volume data, which compare and calculate the difference DELTA of the two, works as detection if difference DELTA is greater than zero
When the corresponding yarn 8 of data is reached between the neat and well spaced mechanism B and neat and well spaced mechanism C of front roller of rear roller, after electric controller E is by control
Roller servo motor 3,6 revolving speed of front roller servo motor increase the rotating ratio between rear roller 2 and lower front roller 5 down to control；
If difference DELTA less than zero, when the corresponding yarn 8 of detection data reach the neat and well spaced mechanism B of the rear roller and neat and well spaced mechanism C of front roller it
Between when, electric controller E reduces lower rear roller 2 by control rear roller servo motor 3,6 revolving speed of front roller servo motor to control
With the rotating ratio between lower front roller 5, neat and well spaced processing is carried out to yarn 8.
By on probation, intelligence degree of the present invention is high, and even and orderly effect is good, and work efficiency is high, easy to operate, improves product
Qualification rate achieves good effect.
