Detailed Description
The invention is further described below with reference to the figures and examples.
The embodiment is as follows:
a full bobbin control system of a winding device of a winding machine comprises a spindle motor, a spindle rod driven by the spindle motor to rotate, a yarn guiding motor and a yarn guiding nozzle driven by the yarn guiding motor to do reciprocating motion, wherein the winding device of the winding machine winds yarns through the spindle rod and the yarn guiding nozzle, the full bobbin control system of the winding device of the winding machine comprises a control module 1, a tension sensor 2, a winding bobbin 3 with flanges at two ends and a raw bobbin 4, the yarns 5 are wound from the raw bobbin to the winding bobbin through the yarn guiding nozzle 6 and form a yarn path between the winding bobbin and the raw bobbin, the tension sensor is arranged on the yarn path formed by the yarns and connected with the control module, the tension sensor is used for collecting the tension of the yarns in real time and transmitting the tension to the control module, and the control module is used for controlling the yarn guiding nozzle to deviate and judging the full bobbin according to the variation condition of the deviated yarns.
The winder winding device can be a device which is common in the market and winds the yarn through a spindle blade and a yarn guide nozzle. The spindle motor and the yarn leading motor are both connected with the control module, and the control module can control the spindle rod and the yarn guide nozzle by controlling the rotating speeds of the spindle motor and the yarn leading motor and the like. When the yarn guide nozzle is adjusted to correct the deviation, the adjusting distance of the yarn guide nozzle is adjusted by controlling the number of positive and negative rotation turns of the yarn guide motor.
The control module can be a singlechip, a MCU and other control devices. Before yarn winding, the operation parameters of the winding device of the winder are determined according to specific yarn winding requirements and input into the control module, and the control module controls the spindle motor and the yarn leading motor according to the operation parameters.
The winding bobbin both ends all are provided with the baffle, and when the yarn was touching the baffle, the yarn can produce the friction with the baffle, and the yarn tension that tension sensor gathered can change thereupon.
A method for controlling the full bobbin of a winding device of a winder, as shown in fig. 2, comprises the following steps:
step one, determining the upper edge position and the lower edge position of a winding bobbin, and starting yarn winding from a preset winding starting position by a yarn guide nozzle;
step two, acquiring the tension of the yarn in real time through a tension sensor in the winding process of the yarn, recording the yarn leading times of a yarn guide nozzle in real time, and offsetting the yarn guide nozzle to the upper edge position or the lower edge position when the yarn leading times of the yarn guide nozzle reach the preset times;
and step three, collecting the yarn tension when the yarn guide nozzle deviates, performing full bobbin judgment according to the yarn tension variation condition, stopping yarn guiding by the yarn guide nozzle if the winding bobbin is judged to be full, sending a full bobbin prompt by the control module, continuing yarn guiding by the yarn guide nozzle if the winding bobbin is judged not to be full, continuing deviation treatment on the yarn guide nozzle after the next yarn guiding is finished, and performing full bobbin judgment according to the yarn tension variation condition.
When full bobbin judgment is carried out according to the yarn tension change condition in the third step, the yarn guiding times when full bobbin judgment is carried out are firstly determined, the yarn tension fluctuation range is determined according to the yarn guiding times, the yarn tension is compared with the yarn tension fluctuation range, if the yarn tension is in the yarn tension fluctuation range, the yarn in the yarn guide nozzle is not rubbed with the flange of the winding bobbin, and the winding bobbin is full; if the yarn tension exceeds the yarn tension fluctuation range, the yarn in the yarn guide nozzle can still rub the flange of the winding bobbin, and the winding bobbin is not full.
After reaching the full bobbin, the yarn guide nozzle will not rub the rib when deviating to the upper edge or the lower edge, and when not reaching the full bobbin, the yarn guide nozzle will rub the rib when deviating to the upper edge or the lower edge. After the friction occurs, the yarn tension fluctuates greatly, so that whether the yarn rubs with the flange or not is judged according to the change condition of the yarn tension, and the full bobbin judgment is realized.
The specific process of determining the yarn tension fluctuation range according to the yarn leading times comprises the following steps: determining influence factors of yarn tension, calculating a correlation coefficient between each influence factor and the yarn tension, setting the weight of each influence factor according to the correlation coefficient, acquiring corresponding data of each influence factor in each yarn drawing process in real time, assigning a score to each influence factor based on the acquired corresponding data of each influence factor, determining a comprehensive fraction of the yarn tension in each yarn drawing process according to the weight and the assigned score of each influence factor, acquiring the yarn tension in the first yarn drawing process, taking the maximum value of the yarn tension and the minimum value of the yarn tension in the first yarn drawing process as an initial yarn tension fluctuation range, adjusting the comprehensive fraction of the yarn tension in the first yarn drawing process, and determining the yarn tension fluctuation range corresponding to each yarn drawing based on the ratio of the comprehensive fractions of the yarn tension in the first yarn drawing process and the initial yarn tension fluctuation range.
As the number of times of yarn feeding increases, the yarn on the surface of the winding package has a different structure, and the fluctuation range of the tension of the yarn is changed by the change of external factors. Therefore, the tension fluctuation range in the first yarn guiding process is used as the initial tension fluctuation range, and the adjustment of the tension fluctuation range is realized based on the change of the influence factors.
The influence factors can be determined to be in positive correlation or negative correlation with respect to the yarn tension through the correlation coefficient, and when each influence factor is assigned, the influence factor value in the first yarn drawing process is taken as a reference, and the assignment is performed based on the change of the influence factor value compared with the influence factor value in the first yarn drawing process and the corresponding correlation coefficient. Since the correlation coefficient can reflect the degree of correlation of the influence factor with respect to the yarn tension variation, the weight division of the influence factor can be realized based on the numerical value of the correlation coefficient, and the weight ratio is larger as the absolute value of the correlation coefficient is closer to the influence factor of 1.
The influencing factors comprise spindle rotation speed fluctuation, external environment, machine running vibration and the like.
And after the upper edge position and the lower edge position of the winding bobbin are determined, the width of the flange of the winding bobbin is measured, the yarn thickness of the full winding bobbin is determined, the yarn leading times of the full winding bobbin are calculated according to the yarn thickness based on the yarn type and the preset operation parameters of the winding device of the winding machine, and the calculated yarn leading times are used as the preset times in the step two.
The position of the upper edge and the position of the lower edge of the winding bobbin can be detected by the positioning sensor. The thickness of the yarn when the winding bobbin is full is equal to the width of the rib of the winding bobbin. The operation parameters of the winding device of the winder comprise the moving speed of the yarn guide nozzle, the yarn winding density and other parameters, and the yarn drawing times required by the yarn thickness when the winding bobbin is full can be determined according to the operation parameters of the winding device of the winder and the yarn type.
And when the winding bobbin is judged to be not full, the offset distance of the yarn guide nozzle is also called, the offset distance of the yarn guide nozzle is added to the movement of the yarn guide motor, and the movement track of the yarn guide nozzle in the next yarn guide process is re-planned based on the movement of the yarn guide motor with the offset distance of the yarn guide nozzle added.
The specific process of adding the offset distance of the yarn guide nozzle to the movement of the yarn guide motor is as follows: the offset direction of the yarn guide nozzle is adjusted, when the yarn guide nozzle shifts towards the upper edge position, the offset distance of the yarn guide nozzle is increased by the stroke of the yarn guide motor, and when the yarn guide nozzle shifts towards the lower edge position, the offset distance of the yarn guide nozzle is reduced by the stroke of the yarn guide motor.
If the yarn guide nozzle carries out offset action in the last yarn guiding process, recording the offset distance of the yarn guide nozzle in the last yarn guiding process, adding the offset distance of the yarn guide nozzle to the movement of the yarn guiding motor, determining the movement track of the yarn guide nozzle in the yarn guiding process by the yarn guiding motor according to the movement of the yarn guiding motor after the offset distance of the yarn guide nozzle is increased, and continuously moving the yarn guide nozzle in the current movement direction based on the movement track ending position in the yarn guiding process to realize offset.
After the yarn guide nozzle deflects, the stroke of the yarn guide motor changes along with the deflection, the back-and-forth movement of the yarn guide nozzle is realized by the back-and-forth rotation of the yarn guide motor, and the back-and-forth rotation of the yarn guide motor also needs to be controlled through the stroke of the yarn guide motor. Therefore, after the offset distance of the yarn guide nozzle is carried out, the offset distance of the yarn guide nozzle is also added to the moving process of the yarn guide motor, and the subsequent yarn guide process can be normally carried out.
The offset distance of the yarn guide nozzle is determined by the distance between the rib position and the yarn start position, and in this embodiment, the offset distance of the yarn guide nozzle is set to 0.8 mm.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
