Abstract
The invention relates to a method to prevent the unexpected breakage of roving frame doffing, which comprises the following steps, (a) test if the doffing is required, (b) when the doffing is not required, return to the step (a) to continue the spinning. When the doffing is required, the flyer rotation speed and the winding rotation rate are arranged so that compared with the time in spinning, the rotation speed of the flyer is reduced. The winding rotation speed is the same as that of the flyer. (c) delay, (d) detect if the flyer positioning is required, (e) if the flyer positioning is not required, the machine is directly stopped with the descending of spindle rails and the doffing. If the flyer positioning is required, the flyer positioning is first implemented, and then the machine is stopped with the descending of spindle rails and the doffing. With the invention, the unexpected breakage can be avoided as mush as possible in the doffing process of the roving frame. Moreover, the yarn length under the flyer compression is lengthened to facilitate the end regeneration when in the spinning again.
Description
Technical field
The invention belongs to the Speed frames technical field, specifically is a kind of method of preventing sudden breaking in doffing of bobbiner.
Background technology
Speed frames can rub mutually and roll with yarn on the spool near the yarn at the pressing device place of flier in the process of doffing along with the decline of down rail, and yarn is broken to be twisted with the fingers thereby make, the most weak fracture thereby the ability that makes yarn herein bear pulling force becomes.Before yarn did not rupture, pressing device produced downward pulling force to the yarn that is positioned at more than it.The weak spot of the above yarn of pressing device has two places: 1, the yarn in the flier yarn road, yarn is subjected to the spinning process (twist for example herein, fiber length) influence, thereby easy and yarn road friction produces the yarn at fracture 2, roller and roller place, so yarn is untwisted very weak herein, is vulnerable to pullling of flier and produces fracture.Practice shows, the accident broken end that Speed frames doff in the process occurs in this two place mostly.
Summary of the invention
The object of the invention is exactly that a kind of method that prevents unexpected broken end in Speed frames doff process is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution used in the present invention is: a kind of method of preventing sudden breaking in doffing of bobbiner, and it may further comprise the steps:
(a) whether detection needs to doff;
(b) when not needing to doff, return step (a), continue spinning; When needs doff, the flier rotating speed is set, winding rotary speed is set, make that the rotating speed of the relative roller rotating speed reduction of rotating speed of flier, the rotating speed of reeling and flier is fast together;
(c) time-delay;
(d) detect whether need the flier location;
(e) if do not need the flier location, then directly stop, fall rail, doff; The flier location is then carried out the flier location earlier if desired, stops, falls rail then, doffs.
Because the technique scheme utilization the invention enables Speed frames can avoid unexpected broken end in the process of doffing, and the length of yarn lengthening under the back flyer presser that doffs, repiece when being convenient to respin as far as possible.

The specific embodiment
Below the specific embodiment of the present invention is described: a kind of method of preventing sudden breaking in doffing of bobbiner is characterized in that may further comprise the steps:
Whether (a) detect and to need to doff, doffing herein doffed or during control is doffed automatically any one for manual control.
(b) when not needing to doff, return main program, promptly return step (a), continue spinning; When needs doff, flier 3 rotating speeds are set, 6 rotating speeds of reeling are set, the rotating speed of reduce, reel when making the rotating speed of flier 3 spin relatively 6 rotating speed and flier 3 is with fast.Reduce when the rotating speed of flier 3 when doffing spins relatively, the pulling force of feasible the doff easier control of process, generation reduces, is difficult for producing unexpected broken end.The rotating speed of coiling 6 and the rotating speed of flier 3 are with speed, then yarn winds less than on the spool 5, roller 1 is also constantly being told yarn simultaneously, make the yarn that forms certain radian on the car face of Speed frames thus, make that the yarn of scope is subjected to pulling force hardly between roller 1 and the pressing device 4, avoided the yarn between roller 1 and the pressing device 4 to produce unexpected fracture as much as possible.Car face herein is the frame surface of the Speed frames between roller 1 and the flier 3.In reality is implemented, reduce when the rotating speed of preferred roller 1 also spins relatively, between roller 1 and the flier 3 length of the cotton yarn of accumulation be 3 centimetres to 5 cm range.
(c) by man-machine interface flier 3 in the step (b) be set, reel 6, the delay time of the rotating speed that doffs of roller 1, meet preset value with the yarn amount of telling of control roller 1.
(d) detect whether need the flier location.
(e) if do not need the flier location, then directly stop, fall rail, doff; The flier location is then carried out the flier location earlier if desired, stops, falls rail then, doffs.
Stop in running, in the down rail decline process, thereby near the yarn at pressing device 4 places can with down rail descend with spool 5 on thread friction roll and make that yarn is broken to be twisted with the fingers, yarn bears the most weak fracture of pulling force thereby make herein.Before yarn ruptures the yarn of pressing device more than 4 produced downward pulling force, under the effect of pulling force, thereby the yarn of formed certain radian moves down slowly and tightens on the car face, for spinning next time ready.Because of yarn broken sth. made by twisting place to length of the yarn of pressing device 4 in the process of doffing adds the length of yarn that moves under the upper yarn alignment of getting on the bus, thereby make the length of yarn lengthening under the back pressing device 4 that doffs, repiece when being convenient to respin.
