Description
Technical field
The utility model relates to a kind of textile machine, in particular for the automatic winder of doff operation, relates to the improvement of automatic winder winding mechanism drive configuration specifically.
Background technology
Automatic winder is owing to have degree of automation height, the excellent characteristics of winding quality, and becomes the Spooling oquipment that generally use in the cotton mill, and automatic winder just day by day towards at a high speed, direction efficient, high yield develops.
Doff groove drum and actuating device thereof are the critical components of automatic winder.Its doff groove drum is one to be provided with the cylinder of cross-helicity groove, and it and is installed in doff bobbin on the bobbin bank by frictional transmission under the driving of electrical motor, to realize the coiling of yarn; The spiral grooves of doff groove drum is then as thread-carrier, and the guiding yarn is reciprocating, finishing the shaping of yarn on bobbin, so the actual dual role of reeling and being shaped of undertaking of doff groove drum.But in the winding process of bobbin-winding machine, along with doff bobbin diameter changes from small to big, to be increased to the groove drum diameter identical or when becoming multiple to concern when the equivalent diameter of bobbin, groove drum surface and bobbin surface produce repeats engagement, yarn can overlap coiling on bobbin, have a strong impact on the cheese outward appearance, even cause bad tube, so people always take to prevent overlapping measure by every means.
The anti-stacked measure of existing bobbin is nothing more than following several: the one, adopt Cop tube, the anti-stacked mode of this passiveness can not be protected overlapping anything but, just after overlapping in continuity, it is poorer in efficient at a high speed or when spinning chemical fibre; The 2nd, the orientation between periodically-varied yarn guiding speed or bobbin and groove drum, this class methods complex structure, the fault rate height only adapts to the low speed reeling condition, and anti-stacked in actual use effect is unsatisfactory; The 3rd, the rotating speed of periodically-varied groove drum, the preceding relatively two kinds of method effects of this anti-stacked method are comparatively desirable, but still exist some obviously not enough, at first independent stack-mounted electronic fine-structure device is arranged owing to adding in this method, complicated in addition groove drum mechanical driving member, make it complex structure, functional reliability is poor, component wear rate height; The starting torque deficiency of next groove drum actuating device, speed of response is slow, is difficult to adapt to the frequent starting and the rotating of groove drum, especially shows more obviously under the high-speed operation situation; In addition, existing this structure and anti-stacked method are easy to take place anti-stacked inefficacy, also are difficult to adapt to the demand for development of high speed, increasingly automated control automatic winder, and therefore its Applicable scope also be subjected to great restriction.
The utility model content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model provides a kind of bobbin-winding machine stray winding mechanism, it is not only simple in structure, reliable, and speed of response is fast, starting torque is big, can adapt to the needs of bobbin-winding machine high-speed operation.
In order to solve the problems of the technologies described above, bobbin-winding machine stray winding structure of the present utility model, comprise the coiling groove drum, described coiling groove drum is fixedly installed in the groove drum rotating shaft, also be installed with groove drum motor rotor in this groove drum rotating shaft, groove drum motor rotor rotatably places in the groove drum stator, and the groove drum stator is fixedly attached on the bobbin-winding machine casing; Described groove drum stator and groove drum motor rotor constitute dc brushless motor; Be provided with two groove drum tachogens at described groove drum rotating shaft correspondence position, the groove drum tachogen is electrically connected with single ingot controller; This list ingot controller also is electrically connected with dc brushless motor.
After adopting said structure, because coiling groove drum and groove drum motor rotor all are fixedly installed in the groove drum rotating shaft, thereby constituted the direct-connected structure of groove drum and motor, this structure has been simplified the groove drum type of drive greatly, it is accurate not only to have transmission, reliable in action, and also motion power consumption is little, abrasive vibration is low, long service life.Again owing in this winding mechanism, adopt dc brushless motor as motive drive source, at first be convenient to substitute fully traditional mechanical commutation with electronic commutation at this motor, dependable performance, fault rate is low, realized the instantaneous change of coiling groove drum rotating speed very easily and safely, to upset the rule of superposition of winding bobbin, play highly desirable anti-stacked effect; Second adopt dc brushless motor have response fast, speed adjusting performance is excellent, the characteristics that starting torque is big, the groove drum of being more convenient for reeling is in the instantaneous variation governing speed of high speed rotating, thereby guaranteed desirable anti-overlapping effect; The 3rd adopts dc brushless motor more to be adapted to the high speed revolution of automatic winder coiling groove drum, guarantees that the groove drum of automatic winder in the process of splicing is frequent suddenly to stop, start and the slow operating needs of falling the yarn.Again owing to adopted the control structure of closing back that groove drum tachogen, single ingot controller and dc brushless motor be electrically connected mutually, rotation direction and rotative speed that single ingot controller can accurately control the coiling groove drum according to the groove drum rotating speed of setting and actual speed, motor rotation is smooth and easy, it is well quick to respond.Also owing to be provided with two groove drum tachogens at groove drum rotating shaft correspondence position, the rotating speed of perception groove drum rotating shaft so exactly, and can accurately judge the hand of rotation of groove drum rotating shaft, the realization of be convenient to reel groove drum coiling run action and anti-azido functional.
A kind of preferred implementation of the present utility model, described groove drum tachogen are along the radially setting of groove drum rotating shaft, and this groove drum tachogen is the Hall-type angular velocity sensor.
Have precision height, good reliability, the excellent characteristics of dynamic property.
The ratio 5～8 of the described groove drum shaft length of another preferred implementation of the present utility model and groove drum motor rotor width.This structure has constituted the slim-lined construction of tumbler, has the little characteristics of rotor inertia, is more conducive to the adjusting of groove drum speed and the realization of anti-stacked efficient.
