Murata self-winding use common problems and solutions (a) N0.21C-S automatic winder Murata, Japan's new high-speed winder at speeds up to 2200 m / min, and the flight control system to increase the anti- so that the device performance can be further improved. N0.21C-S models, high-speed, straight channels yarn and yarn control ring unique design for spinning technical progress has provided a guarantee. While using automatic winder, not only can produce high quality knotless yarn, but also save labor, reduce labor intensity has a significant effect. During use, N0.21C-S advantages are obvious, but there are some problems, control of these issues, is to play the automatic winder effectiveness and improve labor efficiency and ensure that the basis of product quality. Splice failure rate of causes and control measures splicer is a comprehensive parameter reflects the error rate and the yarn splicing errors. Splicing error rate is too high, a large nozzle repeat exercise in futility, prone to the phenomenon of continuous play cop. Cause splicing error rate increased in the following areas: photoelectric yarn sensor attached to spend too much fouling. Always yarn sensor detects the presence of a large nozzle has been movement, causing system failure rate splicer. Large vacuum nozzle is too low. Within the suction duct flower plot plot yarn and more influence of the wind, unable to inhale yarn. Great nozzle from the spool gauge is too large, not suck the yarn, causing splicing errors. Workshop relative humidity, adhesion enhancement yarn, close to the Cheese surface, large nozzle can not capture the yarn breakage, resulting feedback as splicing errors. Flower dust have accumulated large nozzle flower hair or serrated strip is clogged with dust, large nozzle is clogged yarn rotation is not flexible or not in place within the large nozzle yarn channel groove. Yarn suction nozzle yarn channel is blocked, can not catch the yarn at the yarn catching action. Insert sub spindles wrong place, resulting in Bal-con-tracking balloon controller does not drop. Splicing error rate of control measures: Visual Query system, when MIS values ??greater than 10% may be regarded as splicing error rate exceeds the standard, in time to observe the operation state of refurbishment. Every weekday for yarn sensor cleaning, weekly with warm water to clean the sensor device, to avoid false detection sensor. Big Cheese nozzle and timely correction of gauge, large nozzle proximity adjusted to 1.5mm ~ 2.5mm appropriate. Reasonable control of relative humidity workshop. Production shows that self-winding relative humidity should be lower than control standard of ordinary winding. When the relative humidity is greater than 75%, the splicing error rate significantly higher. General should be controlled at around 70%. Remove accumulated dust flower big nozzle trenches, cleaning with gasoline nozzle blade large, clear clogged yarn. Timely clean yarn small nozzle channel. Adjust the position of the sub-spindle is inserted to ensure that sensitive point with the balloon controller unwinding yarn declined. Unwinding bad Causes and Control Measures unwinding bad one winding common problems. Because self-winding line speed for the spool winding quality requirements increase accordingly. The main impact of the unwinding of adverse yield, prone to large yarn or the yarn non-empty tube sent, affecting productivity. Unwinding of the main reasons poor: Bal-con tracking balloon flower ring product, debris stuck to the surface, resulting in delivery pipe unwinding of malfunction. Insert sub spindles wrong place, too forward or rearward. Spinning spool off circle, resulting in the process of unwinding yarn is assembled into a group, small nozzle can not capture the yarn. Yarn production maintenance, not good bead plate when replacing the yarn, production machinery bad yarn, winding density caused by uneven and overlapping winding, unwinding in the form of off circle. Bobbin tube rupture glitch, resulting in unwinding of repeated breakage. Doffing evolved, unwinding off circle, the impact of unwinding. Doffing spun at low speed for too long after hooking yarn winding layer structure does not close, causing unseating. Unwinding poor control measures: Bal-con tracking balloon controller cleaned regularly fly, reducing the impact of the unwinding of factors. Adjust the position of the sub-spindle is inserted. When replacing bead yarn as much as possible in a large yarn replacement, timely replacement doffing prevent yarn unwinding effect in the middle of the disc. Control the spun yarn forming tube and doffing height of burst burr bobbin timely pick excised. Causes and Control Measures bobbin winding operation from high speed, winding bobbins also require higher quality to its adapting. Because in the actual production of the bobbin hardness, concentricity and some mechanical factors affecting the stability of operation, resulting in the production of paper tube flying off. Fly bobbin not only affect the yield and quality, and is likely to cause personal accidents. The main reason for flying bobbins are: paper tube hardness, concentricity, roundness, angle, length, leaving the tail yarn opening size of the first inner diameter failed. Ferrule dye or pigment paint on a small cartridge slot deposited projections, expanding the distance of the holding, the impact of stable operation. Gamma cradle improper initial pressure process settings. Gamma cradle chuck refueling cycle is too long, the impact of control on the Cheese. Deceleration rate is too high. Generally set the range of 50% to 70% linear velocity of more than 70% gamma cradle size paper tube clamp force for large, easy to make paper tube deformation caused by flight control. Have left the bulk of paper yarn tail of small mouth, depth too easily cause paper tube flying off. Spun yarn faults too, gamma cradle action too often, the force of the paper tube is large, resulting in flight control. In the installation of anti-fly tube apparatus circumstances, should pay attention to the following aspects: good reasonable selection of quality, high hardness of paper, a reasonable choice of network yarn speed, so combine the two, so that the tube can not fly quality assurance. Small left side chuck-deposited pigments, paints cleared up, to prevent the operation of Cheese caused by an imbalance of flight control. Color selection of paper tube head of the selection printed color as possible. A reasonable set of bobbins early pressure device technology to ensure the tightness of 8mm ~ 10mm initial winding layer. Gamma cradle chuck grasp refueling cycle. Gamma cradle is an important part of the formation of the package. Fuel cycle is too long, it will cause bearing damage, weakening of the Cheese of control, forming a tube fly. In strict accordance with the provisions of the choice of grease specified when refueling. Fuel cycle, the winding speed of 1,500 m / min or less for 12 months, the winding speed of 1,500 m / min or more six months is appropriate. Come assurance 0.5 grams per ingot / ingots. Depending on the speed to select the appropriate paper tube. Recurrent control spun yarn faults and sporadic yarn defects, reducing the number of windings acting from the source control. Murata self-winding use in solving common problems and quality control methods hairiness yarn faults compressed air if the compressed air pressure is insufficient, will cause the air splicer knot strength is not enough, not even tie a knot, causing repeated operation of the upper part of the cheese, which Effect of hairiness. Control measures: pressure 0.637mpa, oil content of 0.07g / m3 or less. Bobbin chuck center position adjusting general head contact with grooved, big chuck and grooved maintained at between 1 ± 0.5mm, this dimension is called the B size. If you replace the paper tube, according to a new paper tube size to adjust the center position of the bobbin chuck, to maintain its position B size. If the B size is too small, the friction of the bobbin and grooved generated will increase, leading to increased hairiness. In addition, the bulk of the large distance between the grips bobbin called A size, paper tube length of less than 174.1mm, A size 11 ± 0.5mm, paper tube of length greater than 174.1mm, A size 13 ± 0 .5mm. A size is too large, easy to wound yarn. Great nozzle proximity and parallelism adjustment of the nozzle when a large close too small, when parallelism is not good, the nozzle may encounter bobbin, make Cheese shaving surface; when approaching too large, the suction mouth head too hard to find, duplicate Zhang head, since the grooved friction and absorb the force, is also causing increased hairiness. In the case of a bobbin having a diameter of 160mm, adjust the degree of parallel between the nozzle and the bobbin; in the case of a bobbin having a diameter of 90mm, a large adjustment proximity between the nozzle and the bobbin. Adjust the needle position. Winding tension control measures according to the size of the winding tension winding speed, yarn strength and hardness control cheese. Tension voltage value does not recommend changes, if necessary to adjust the winding tension, to change the yarn strength and hardness Cheese. To reduce the hairiness, Cheese hardness is too large to grasp as well. When the plug is inserted spindles sub-center position adjustment spindles and Child with Bal-con wrong, the yarn unwinding at high speed to produce a balloon balloon controller will collide, causing increased hairiness. When inserted before sub-spindles and Bal-con reach the lowest position, turn the dial so that the air traffic control center and movable Bal-con centering, Bal-con can be inserted on the spindles move child support points. Tracking balloon control ring on the upper limit position control if the balloon is defined too high, in the long unwinding balloon longitudinal, horizontal increases, yarn collision can control the inside of the cover ring angry, resulting in hairiness. Also cover the inside of the balloon control is not smooth, it will increase the hairiness. Once the sensor balloon controller failure, not with the spools to a reduction, it will also cause the balloon too big impact hairiness. Clean carrier path inside the yarn guide channel has burrs, grooves, cotton wax, oil adhesion phenomena should be promptly cleaned, especially the clearer channel and ceramic pieces to be cleaned regularly. Forming bad cop, off circle, the lowest position of the cop will affect low hairiness. Sudden hairiness yarn defect causes and control measures increased from the normal yarn hairiness to coning is generally 2 to 3 times, and sudden hairiness hairiness is significantly different from the normal growth, usually in 6 to 7 times. Sudden sudden oncoming hairiness, a wide range of great harm, not control. Self-winding sudden hairiness reasons usually are: relative humidity is too low, the yarn passage astringent, fluffy yarn, poor cohesion, sudden hairiness is formed through friction. From raw materials to regain instability of yarn, absorption and desorption does not meet the requirements of production process, through the self-winding speed when unwinding the yarn winding point and release point and mechanical friction, the formation of a sudden hairiness. Spinning Core inner tube bakelite too large, resulting in yarn movement when doing plug, plug spindles malposition, resulting in Bal-con trace gas rings does not work, the balloon is too large trigger hairiness. Tension cylinder short of oil or tenser dirty, causing molding defects, increased hairiness. Sudden hairiness control measures: self-winding passage wipe cleaned regularly to ensure smooth, no oil, reducing friction formation sudden hairiness. Reasonable humidification from blowroom to spinning process, humidity control humidity caused by uneven sided. The entire process usually set up two control points: Critical Control blowroom Cotton and roving regain regain volume. Standard: Cotton opening and cleaning regain control over the volume of 7.5%; roving resurgence control 6.1% -6.5% will help control sudden hairiness. Strict selection of spinning tube of spinning tube to be used with the original grooved from bakelite Core inner diameter winding choice is more complex specifications. Adjust ratchet insert spindles, bobbins and make balloon tracking center of the ring in a straight line. Tension cylinder regularly refuel, tension exploded periodically with warm water, the cycle generally three months is appropriate. Electrical parameters determine electricity clear set clear parameters product quality assurance. Yarn faults parameter is one of the key factors that determine the quality of the fabric, should be determined in accordance with customer requirements for quality of cloth, easy to operate when renovations cloth. At the same time it should take into account the number and productivity of the yarn defects, to remove harmful yarn faults based. Parameters to determine the principles: knitting yarn neps detail requirements, set specific parameters: + 300% cotton knot diameter and a length of 1.0mm, -30% Details diameter, length 10mm. Woven yarn requirements for slub high, usually set short and thick section of + 150%, the length of 1.5mm: Long thick diameter + 45%, causes internal and external reasons for the length of 10mm color a simple cheese dyeing yarn dyeing color color flowers 1.1 Cheese mass winding bobbins winding density to ensure consistent, winding hardness is generally 27 ± 2 (Shore hardness). If the winding hardness is too small, the impact will damage the process of dyeing yarn by the air flow, resulting in poor shape, the dye can also cause local short circuit, make Cheese dyeing shades, produce dyed flowers; if the winding hardness is too large, stained liquid impermeable domestic and external color. 1.2 Equipment operating conditions in terms of equipment, lack of primary pump power and switching equipment is not in place, a computer malfunction indicator dye vat flange leaks, will reduce the flow rate will cause severe color flowers. 1.2.1 insufficient pump power and change is not in place when the device is not operating salt dissolves it into vat, into the pump leaf and salt rub, and the gap between the pump increases, caused by insufficient pump power; goose neck tube commutation means piston running bad, the trip is not in place, resulting in staining pressure reach. 1.2.2 vat components installed after the yarn due to leakage, Creel heavy weight lifting occurs during the collision with the bottom vat, so that the welding point vat bottom coil cracking, loose screws, thread rod and chassis seal well, resulting in leakage. 1.2.3 Temperature control system due to infiltration into the dripping cylinder temperature needle, so that the temperature sensing needle malfunctions, causing the temperature and the actual temperature of the display does not match the temperature control system, resulting in inaccurate temperature dyeing, the hue deviations occur . Impurity 1.3 Process 1.3.1 before pre-treatment process, the capillary effect, whiteness, washed pH and hydrogen peroxide to remove the case would affect the uniformity of dyeing. 1.3.2 select the appropriate dye and dyeing auxiliaries, dyeing process designed to ensure the dyeing quality. Process design is not good, choose RGB poor compatibility, it can also cause color flowers. 2 prevent color color flower quality measures 2.1 Cheese Cheese shaped to strictly eliminate dumbbell yarn, yarn horn, overlapping yarn, yarn and hard-edge leak eye yarn, winding density should be controlled within the desired range, excellent too loose to be singled out, Cheese same size. 2.2 equipment maintenance to ensure the normal operation of the problems described above to be checked regularly, so as to ensure a well-functioning and stable dyeing equipment quality. Regular water and steam valves to check to see whether the open and closed lax phenomenon is not flexible, strengthen equipment maintenance. 2.3 pre-treatment process before selecting treatment process must be cooked, cook evenly in order to staining. To shorten the time, using the same scouring bleaching bath. Process recipe g / L 3O% sodium hydroxide penetrant 2 2 4 scouring agent hydrogen peroxide stabilizer 6 3 pretreatment curve (Figure 1). 2.4 vat dyeing process selection warming by steam stop valve control, the use of B-type vinylsulphone eleven Monochlorotriazine bifunctional reactive dye which there are two active groups, show good levelness and weight reproducibility.
