N0.21C—The S automatic winder is a new type of high-speed winder from Murata, Japan, with a maximum speed of 2200 m/min, and the addition of an anti-flying tube device further improves the performance of the equipment. The high speed of the N0.21C-S model, the unique design of the yarn straight channel and the yarn control ring, provide a guarantee for the advancement of spinning technology. At the same time, the use of automatic winder can not only produce high-quality knotless yarn, but also have a significant effect on saving labor and reducing labor intensity of workers.
In the process of use, the advantages of N0.21C-S are obvious, but there are also some problems. Controlling these problems is the basis for exerting the function of automatic winder, improving labor efficiency and ensuring product quality. Reasons and control measures for the high splicing error rate The splicing error rate is a comprehensive parameter reflecting splicing and yarn loading errors. When the splicing error rate is too high, the large suction nozzle repeats useless work, and the phenomenon of continuous cops is likely to occur.
The reasons for the increase in the splicing error rate are as follows: the photoelectric yarn sensor has too much dust and flowers. The sensor always detects the presence of yarn, and the large suction nozzle keeps moving, resulting in a high rate of splicing errors in the system. The negative pressure of the large nozzle is too low.
There is a lot of flowers and yarns accumulated in the suction duct, which affects the wind force and cannot absorb the yarn. The distance between the large suction nozzle and the cop yarn is too large, and the yarn cannot be sucked, resulting in splicing errors. The relative humidity in the workshop is too high, the adhesion of the yarn is enhanced, and it is close to the surface of the packaged yarn. The large suction nozzle cannot catch the yarn breakage, resulting in the feedback of splicing errors.
There is dust accumulated in the groove of the yarn channel of the large suction nozzle, the sawtooth of the large suction nozzle is blocked by flower hair or dust, and the rotation of the large suction nozzle is blocked by the back thread, which is inflexible or not in place. The yarn suction channel of the suction nozzle is blocked by the return yarn, and the yarn cannot be caught during the yarn catching action. The position of the yarn insertion spindle is wrong, which causes the Bal-con tracking balloon controller not to descend.
Control measures for splicing error rate: through the visual query system, when the MIS value is greater than 10%, it can be regarded as the splicing error rate exceeding the standard, and the operation status can be observed in time for repair. The yarn sensor is cleaned every working day, and the sensor device is wiped with warm water every week to avoid false detection of the sensor. Correct the distance between the large suction nozzle and the yarn in time, and adjust the proximity of the large suction nozzle to 1.5mm ~ 2.5mm.
Reasonably control the relative humidity of the workshop. It has been shown in production that the relative humidity of self-winding should be lower than the control standard of ordinary winding. When the relative humidity is greater than 75%, the splicing error rate increases significantly.
Generally, it should be controlled at about 70%. Remove the accumulated dust in the groove of the large suction nozzle, clean the saw blade of the large suction nozzle with gasoline, and remove the blocked return wire. Clean up the return wire in the small nozzle channel in time.
Adjust the position of the yarn insertion spindle to ensure that the photosensitive point of the balloon controller drops with the unwinding of the yarn. Reasons and control measures for poor unwinding Poor unwinding is one of the common problems in winding. Due to the increase of the linear speed of the self-winding, the corresponding requirements for the winding quality of the cops are increased.
Poor unwinding mainly affects the output, and it is easy to send out large or medium yarns in non-empty tubes, which affects the production efficiency. The main reasons for the poor unwinding are: The Bal-con tracking balloon ring has accumulated flowers, and the surface is adhering to the sundries, which causes the misoperation of the feeding tube during unwinding. The position of the yarn insertion spindle is wrong, too far forward or backward.
The spun bobbin is out of the loop, causing the yarn to gather into a group during the unwinding process, and the small suction nozzle cannot catch the yarn. In the production and maintenance of spun yarn, the yarn tail is not coiled when the traveler is replaced, and the mechanical failure of the yarn during production results in uneven winding density and overlapping winding, resulting in loops during unwinding. The bobbin bobbin bursts with burrs, causing repeated end breaks during unwinding.
The doffing appears, and the loop is unwound during unwinding, which affects the unwinding. The low-speed running time is too long after the doffing of the spun yarn, and the structure of the winding layer of the yarn is not tight, resulting in the looping. Poor unwinding control measures: Bal—The con tracking balloon controller regularly cleans the flying waste to reduce the factors that affect the unwinding.
Adjust the position of the yarn insertion spindle. When replacing the traveler with the spun yarn, try to replace the large yarn as much as possible, and doff the yarn in time after the replacement to prevent the unwinding of the yarn in the middle coil. Control the bobbin formation and doffing height of the spun yarn, and pick out the bobbins with broken burrs in time.

Control the bobbin formation and doffing height of the spun yarn, and pick out the bobbins with broken burrs in time.
Causes and control measures of the flying bobbin The high running speed of the self-winding, the winding bobbin also needs a higher quality to adapt to it. In actual production, due to the hardness, concentricity of the bobbin and some mechanical reasons, the stability of the operation is affected, causing the paper tube to fly off during production. The bobbin tube not only affects the output and quality, but also easily causes personal safety accidents.
The main reasons for flying bobbins are: paper tube hardness, concentricity, roundness, angle, length, tail yarn opening, and unqualified inner diameters of large and small heads. The dyed paint or pigment of the tube head accumulates on the convex groove of the small chuck, which enlarges the clamping distance and affects the stable operation. The initial pressure process of the gamma cradle is improperly set.
The oiling cycle of the gamma cradle chuck is too long, which affects the control of the bobbin. The deceleration speed value is too high. The general setting range is 50% to 70% of the online speed. When it exceeds 70%, the gamma cradle size chuck has a large force on the paper tube, which is easy to deform the paper tube and cause the flying tube.
The large end of the paper tube has a small opening for the yarn tail, and if the depth is too large, it is easy to cause the paper tube to fly off. There are too many yarn defects in the spun yarn, the action of the gamma cradle is too frequent, and the force on the paper tube is large, causing the flying tube. In the case of installing the anti-flying tube device, the following aspects should be paid attention to: reasonable selection of paper tubes with good quality and high hardness, and reasonable selection of winding yarn speed, so as to combine the two organically, so as to achieve both no flying tube and high hardness. Quality assurance.
The paint and paint accumulated on the small chuck on the left are cleaned up in time to prevent the flying tube caused by the unbalance of the yarn in operation. Use the color of the paper tube head as much as possible to use the printed color. Reasonably set the initial pressure device process of the bobbin to ensure the tightness of the initial winding layer of 8mm to 10mm.
Grasp the refueling cycle of the gamma cradle chuck. The gamma cradle is an important part of forming the package. If the refueling cycle is too long, the bearing will be damaged, the control force of the bobbin yarn will be weakened, and the flying tube will be formed.
When refueling, use the specified lubricating grease in strict accordance with the regulations. The refueling cycle is 12 months for the winding speed below 1500 m/min, and 6 months for the winding speed above 1500 m/min. The amount of refueling is guaranteed to be 0.5 grams per ingot per ingot.
Choose the right paper tube according to the speed. Control the frequent yarn defects and occasional yarn defects of spun yarn, and reduce the number of work done by the winding from the source.
