Background technology

The method for winding of yarn commonly used adopts following apparatus to realize at present:

Be controlled to be example with single ingot, stepping motor connects a yarn guiding wheel, and rotating drive yarn guiding wheel and Timing Belt driving thread-carrier sway by stepping motor realize the horizontal winding displacement motion of yarn; The coiling motor rotarily drives near the motion of realize reeling of its cylinder yarn, after above-mentioned two kinds of motions are synthetic and show as yarn and be wound on back and forth a yarn surface with the shape of helix line.Wherein, thread-carrier is for the crank motion by himself the yarn guiding also to be wound in a yarn surface more uniformly.

But along with the coiling of yarn towards high speed development more and more, the acceleration/accel of thread-carrier is difficult to keep constant under the condition of high-speed winding, make the motion of thread-carrier and the synchronized movement of cylinder yarn easily produce deviation, yarn is not tightly wrapped just come off from a cylinder yarn surface, this kind phenomenon is called doffs.The generation of doffing will produce defect ware, and cause to produce and pause, and affect production efficiency.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand the following specific embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

See also principal organ's scheme drawing of wind2 shown in Figure 1, wherein, the thread-carrier motor 6(that this wind2 comprises coiling motor 1, be used for to survey first speed measuring device 2 of cylinder yarn rotating speed, is used for surveying the second speed measuring device 3 of coiling motor speed, the thread-carrier 4 that is used for directing thread 9, controller 5, control thread-carrier 4 are reciprocating in the present embodiment, this thread-carrier motor 6 is a stepping motor), the yarn guiding wheel 7 that links to each other with 6 rotating shafts of thread-carrier motor, be used for cylinder yarn 8 that yarn 9 reels, be used for driving the Timing Belt 10 that thread-carrier 4 moves.In the yarn winding process, this thread-carrier motor 6 drives yarn guiding wheel 7 by forward and counter-rotating, and yarn guiding wheel 7 drives Timing Belts 10, and Timing Belt 10 drives the thread-carrier 4 that is located thereon again and does horizontal high speed crank motion; The motor 1 of reeling simultaneously drives cylinder yarn 8 and does vertical rotation, and by traverse motion and the synthesizing that cylinder yarn 8 vertically rotatablely moves of thread-carrier 4, the shape that yarn 9 shows as with helix line is wound on a yarn 8 surfaces back and forth.Be denoted as the concrete technology parameter that 11 dotted line represents external setting-up among the figure.

The concept of an intersection angle by name is arranged in this method for winding, see also Figure 1 and Figure 2, intersection angle а is the angle а that thread-carrier 4 cross velocitys and cylinder yarn 8 longitudinal velocitys form right-angled triangle.Intersection angle а directly has influence on profile and the quality thereof of a yarn 8 in the variation in the yarn process.And owing to the longitudinal velocity of cylinder yarn 8 in the yarn process is substantially constant, so the velocity variations of thread-carrier 4 is exactly the leading factor that intersection angle а changes.

See also Fig. 1 and in conjunction with shown in Figure 2, thread-carrier 4 is when reciprocating, it need to have the process of acceleration and deceleration when moving to the two ends of a yarn 8, be that thread-carrier 4 is accelerated movement from cylinder yarn 8 one ends when the other end moves specifically, after being added to certain speed, change uniform movement into, be decelerated movement when being about to arrive the other end, make amount that yarn 9 reels at the two ends of cylinder yarn 8 less than the amount of reeling at cylinder yarn 8 middle parts with this.Described controller 5 calculates thread-carrier motor 6 at the Acceleration and deceleration time of cylinder yarn end according to the running velocity of thread-carrier motor 6 middle bodies, and as the control expected value this Acceleration and deceleration time is limited in the rational scope this Acceleration and deceleration time.The diameter of cylinder yarn 8 is calculated through controller 5 by the first speed measuring device 2 and the second speed measuring device 3 measured speed datas, and thread-carrier motor 6 is set at the Acceleration and deceleration time of end operation according to the diameter of cylinder yarn 8, and according to this Acceleration and deceleration time, speed control is carried out to thread-carrier 4 in end at described cylinder yarn 8, and make the invariablenes turning speed of the corresponding cylinder of thread-carrier 4 acceleration and deceleration yarn 8, can not produce thread-carrier 4 acceleration and deceleration and produce with the phenomenon of the rotating speed dislocation of cylinder yarn 8 and doff.It should be noted that the increase (because the yarn of reeling is more and more) along with spooler cheese diameter 8, the Acceleration and deceleration time of controller 5 control thread-carrier motors 6 in cylinder yarn 8 ends slowly need to be diminished according to cylinder yarn 8 diameters are regular.Because spooler cheese diameter 8 increase in same time coiling once the length of circle with elongated, need the control Acceleration and deceleration time according to regular slowly the diminishing of cylinder yarn 8 diameters thread-carrier 4 final uniform velocity are diminished with the longer yarn 9 of coiling within the identical time.And along with the lasting increase of cylinder yarn 8 diameters, actual at the acceleration/accel of cylinder yarn 8 ends and deceleration/decel to last controller 5 control thread-carrier motors 6 is necessarily, can effectively avoid the appearance of doffing.

See also the speed control curve of the thread-carrier 4 of whole winding process shown in Figure 3, and in conjunction with Fig. 1.Thread-carrier 4 has a process of accelerating and slowing down in cylinder yarn 8 ends, the maximum speed of solid line for reaching according to motor and controller 5 ardware feature thread-carriers among the figure, dotted line is the speed (actual speed can not be higher than maximum speed) of thread-carrier 4 in the reciprocal process of reality among the figure, we establish thread-carrier 4 in the example needs 10ms from speed zero to maximum speed, then in pick-up time and deceleration time of actual winding process middle yarn guider:

T=V*10/Vmax

In case the average velociity at middle body determined, Acceleration and deceleration time just determined, and acceleration/accel constant in the whole process, and actv. has been avoided the appearance of doffing.And by regulating intersection angle а control aim curve, density that can adjustment barrel yarn 8, satisfy the requirement of some special process, the variation (seeing also shown in Figure 2) of intersection angle а in cylinder yarn 8 winding process, can be with serving special coiling than (reeling than being the once revolutions of cylinder yarn 8 of thread-carrier 4 crank motions) phenomenon of generation yarn overlying, easily produce yarn and produce jump phenomena at this lap, because jump phenomena causes relatively sharply changing of intersection angle, thereupon and may occur at cylinder yarn edge stepped, and occuring, stair-stepping cylinder yarn generally is regarded as inferior goods, here the mode of control is, intersection angle а according to target controls curvilinear motion, when running into jump phenomena, get its aviation value at middle body and remove to calculate Acceleration and deceleration time as motor in the speed of middle body, thereby make a yarn 8 end faces even, prevent the formation of stepped cylinder yarn.
