Description
Technical field
The present invention relates to a kind of control methods of the automatic repiece of fly frame, belong to fly frame technical field.
Background technique
Currently, automatic doffing roving frame, thickness connection transportation system and collective's doffing spinning machine is more and more set of answers
It uses in textile enterprise, and automatic repiece success rate is to verify an important indicator of automatic doffing roving frame the degree of automation.
The repiece mode of present fly frame predominantly repiece mode and automatic repiece mode at hand.
Manual repiece mode more application is in without automatic doffing roving frame, after referring to the full yarn of fly frame spinning, down rail
Set to super demotion, the bobbin manually taken full spool away, change sky, down rail rise to after string-up position manually by yarn first
One is adhered on bobbin suede band, subsequently into spinning state.Because fly frame number of spindles is more usually more than 120 ingots, therefore hand
Dynamic repiece mode labor intensity is larger, and time-consuming, causes production efficiency low.
Automatic repiece mode more application is in automatic doffing roving frame, and fly frame spins after full yarn, down rail to super demotion
It sets, by taking yarn feeding device to take full spool away automatically, changing empty bobbin, down rail is risen to after string-up position through certain rotation
Turn mode to adhere to yarn and thread head on bobbin suede band, subsequently into spinning state.
Currently, there are mainly three types of the rotation modes of automatic repiece:
First way: after bobbin to string-up position, by increasing the revolving speed of flier, and roller, bobbin, down rail liter
Drop then carries out following operation according to the matching normal spinning speed of setting.This mode can only make a part of yarn and thread head viscous
It is attached on bobbin suede band；And failed repiece just needs manually repiece, remaining other yarn and thread head is adhered to bobbin suede
Band.Such mode is higher to the concentricity requirement coherence request of flyer presser and bobbin, and otherwise flyer presser is the same as between bobbin
There can be certain interval, and after long-play, this gap size is difficult to keep unanimously, and this inconsistency can reduce automatic life
The success rate of head, is unable to meet production demand.Secondly as ingot speed moment is too fast, the yarn of failed repiece can be in fly frame
The head that floats is generated on table top, a large amount of flyings is caused to descend slowly and lightly onto sliver or rove item, is formed yarn defect, is made yarn quality, yield substantially
It reduces.
The second way: after bobbin to string-up position, roller and down rail are remained stationary, flier and bobbin first according to
The opposite direction spin for some time of normal direction stops；Then roller and down rail are still motionless, but flier and bobbin are pressed again
Stop according to the consistent direction spin for some time in direction is operated normally, finally enters normal spinning state.
The third mode, after bobbin to string-up position, roller and down rail are remained stationary, and flier and bobbin first according to
The direction spin for some time opposite with normal direction stops；Then four motors respectively drive roller, flier, down rail liter
Drop, bobbin are operated according to normal spinning speed and direction.
The above-mentioned second way and the third mode are remained stationary by roller and down rail, and flier and bobbin
It reversely rotates, to reach automatic repiece mode.This repiece mode is to be acted by reducing roller and down rail, and make flier
The step of with bobbin according still further to the stopping of direction spin for some time is operated normally, and automatic repiece success is improved to a certain extent
Rate.But also because of control roller and down rail is motionless and the reversion of flier and bobbin is all not belonging to normal spinning time, not only can
Production efficiency is influenced, while control action is all comparatively laborious.Secondly, the reversion of flier and bobbin is to carry out one to normal yarn
The process of a untwisting, time length will appear back twisting, yarn qualities not only influenced, and during automatic repiece, because of yarn
Untwisting and lead to broken yarn or generate above flier to float head.Moreover the whole trolley of fly frame is usually more than 120 ingots, and flier pressure
The flexibility ratio of the palm not can guarantee unanimously, during flier and bobbin are rewound, the revolving speed needed is inconsistent, and speed is slow to be will lead to
Flyer presser can not be attached on bobbin suede band, and speed is fast to be will lead to flyer presser and flick from bobbin suede band, but will affect from
Dynamic repiece success rate.
