The servo system for eliminating the ring spinning frame roller torsional vibration mainly comprises a servo driver, a servo motor and a programmable logic controller. The servo driver directly controls the servo motor. The servo motor provides rotating torque compensation for two rows of front rollers at a lathe tailstock portion. The servo driver is connected with the programmable logic controller. Meanwhile, the programmable logic controller receives start-up signals. The servo driver controls the servo motor in a torque mode. The servo system for eliminating the ring spinning frame roller torsional vibration has the advantages of effectively eliminating roller torsional vibration at the lathe tailstock portion, achieving rotating balance of lathe headstock and lathe tailstock, prolonging service life of rollers, preventing the rollers from breaking; lightening gear load of equipment from a static state to a dynamic state, prolonging service life of the equipment; reducing main motor load of the equipment from a static state to a dynamic state.
Description
Technical field
The utility model relates to the ring spinning new technical field, the servo-control system of a kind of specifically roller eliminated that can be installed at fine spining machine long vehicle tailstock place torsional oscillation when especially the large-diameter hollow roller uses.
Background technology
Spinning process is last procedure of resultant yarn, and it is spun into the spun yarn that has certain special number, meets the correlated quality standard by rove being carried out tens of times drawing-off and twisting, the final decision of the quality of spun yarn quality the quality of finished product.The RING SPINNING technology is the most a kind of spinning technique of present domestic and international application, ring throstle also is the maximum equipment of present textile enterprise use amount, the production-scale size of textile mills is represented with the total number of spindles of fine spining machine, the height of fine spining machine per unit area yield has reflected the level of production of textile enterprise, and indexs such as the quality of spun yarn, feed product power consumption, labor productivity etc. are the embodiments of textile enterprise's technology and managerial skills.Therefore, ring throstle is the spinning enterprise equipment of core the most, and its performance has directly determined the whole enterprise technical merit.
At present, the fine spining machine drafting system that domestic main flow is used adopts three roller forms, wherein in, rear roller is connected with front roller by gear, front roller is by main driven by motor.Therefore, behind the main electric motor starting, the front roller that at first drives the headstock part is rotated by static the beginning, is delivered to tail part then gradually, when ride is longer, can make roller produce the torsional oscillation effect, when especially current roller diameter, quality are big, roller because and stronger static friction effect between the roller, the torsional oscillation effect is more obvious, even cause the torsional deflection of roller, cause serious economy loss to enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of servo-control system of roller torsional oscillation can eliminate the fine spining machine long vehicle and start the time.
Servo-control system described in the utility model mainly comprises servo-driver, servomotor and programmable logic controller (PLC), servo-driver is directly controlled servomotor, servomotor is successively by connecting gear, reduction gearing, band transmission synchronously drives the left hand front roller and rotates, simultaneously successively by connecting gear, tumbler gear, reduction gearing, band transmission synchronously drives right hand front roller and rotates, servo-driver links to each other with programmable logic controller (PLC), programmable logic controller (PLC) receives starting signal simultaneously, with the closed loop controlling structure of realizing that servomotor rotates tailstock place front roller.
The control model of servo-drive system described in the utility model is a torque mode, is installed in fine spining machine tailstock place, the front roller of tail part is rotated give certain torque compensation, to realize eliminating the roller torsional oscillation.
During driving, owing to there is bigger stiction between front roller and the rubber roll, and main drive of motor is sent to the tailstock by headstock needs the regular hour, so the roller torsional oscillation is the most remarkable, therefore, for realizing headstock and tailstock place roller rotary balance, during driving, servomotor is worked in the full load mode, gives the torque compensation of tailstock roller with maximum, the stepped decline of live load then finally drops to 30% ~ 50% left and right sides steady operation of roller driving torque.
The servo-control system that the utility model provides can effectively be eliminated the roller torsional oscillation at tailstock place, realizes headstock and tailstock rotary balance, can prolong roller service life, prevent the roller fracture; Can alleviate equipment by quiet load, prolong its service life to moving process middle gear; Help minimizing equipment by quiet in the moving process main motor load.
Description of drawings
Fig. 1 is a servo-control system block diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of servo-control system of eliminating the roller torsional oscillation comprises servo-driver 3, servomotor 4, programmable logic controller (PLC) 2, wherein servomotor 4 is by motor shaft 8 driven gears 11, gear 11 is meshing with each other with gear 12 and is connected, gear 12 is connected with gear 14 by connecting axle 10, gear 14 is by synchronously with 19 gears 17 that drive on the left hand front rollers 6, the final torque compensation of realizing 4 pairs of left hand front rollers 6 of servomotor, gear train 11 and 12 and gear train 14 and 17 realize the control of slowing down jointly; Gear 12 is meshing with each other with gear 13 and is connected, gear 13 is connected with gear 15 by connecting axle 9, gear 15 is by synchronously with 19 gears 16 that drive on the right hand front rollers 5, the final torque compensation of realizing 4 pairs of right hand front rollers 5 of servomotor, gear 13 is realized Rotation With Changing to effect, gear train 11 and 12 and gear train 15 and 16 realize the control of slowing down jointly; Servo-driver 3 links to each other with programmable logic controller (PLC) 2, and programmable logic controller (PLC) 2 is connected with fine spining machine starting signal system 1 simultaneously.
The method of work of above-mentioned servo-control system, for above-mentioned servo-control system is installed in the fine spining machine tailstock: during driving, programmable logic controller (PLC) 2 receives behind the starting signal that fine spining machine starting signal system 1 sends by servo-driver 3 control servomotors 4 and operates at full capacity with torque mode, give the torque compensation of tailstock place two row front rollers by the gear connected system with maximum, the stepped decline of servomotor 4 live loads then, finally drop to 30% ~ 50% left and right sides steady operation of roller driving torque, to realize headstock and tailstock place roller rotary balance.When breaking down, programmable logic controller (PLC) 2 sends scram signal 7.
After eliminating, the roller torsional oscillation helps eliminating because the mechanical wave that the roller torsional oscillation is produced; Can prolong roller service life, prevent the roller fracture; Can alleviate equipment by quiet load, prolong its service life to moving process middle gear; Help minimizing equipment by quiet in the moving process main motor load.
