Description
Technical field
The present invention relates to ring spinning new technical field, specifically a kind of can be installed at fine spining machine long vehicle tailstock place servo-control system and utilize it to eliminate roller produces torsional oscillation method when especially large-diameter hollow roller uses.
Background technology
Spinning process is last procedure of resultant yarn, and it is spun into by carrying out the drawing-off of decades of times to rove and twisting the spun yarn having certain special number, meet related quality criterion, and the quality of spun yarn finally determines the quality of finished product.RING SPINNING technology is current domestic and international application the most a kind of spinning technique, ring throstle is also the equipment that current textile enterprise use amount is maximum, the production-scale size of textile mills represents with the total number of spindles of fine spining machine, the height of fine spining machine per unit area yield reflects the level of production of textile enterprise, the embodiment of index, labor productivity Deng Shi textile enterprise technology and the managerial skills such as quality, feed product power consumption of spun yarn.Therefore, ring throstle is the equipment of spinning enterprise core the most, and its performance directly determines the overall technology level of enterprise.
At present, the drafting system of spinning frame that domestic main flow uses adopts three roller forms, and Qi Zhongzhong, rear roller are connected with front roller by gear, and front roller is driven by mair motor.Therefore, after mair motor starts, first drive the front roller of vehicle head part to rotate by static, be then delivered to tail part gradually, when ride is longer, roller can be made to produce torsional oscillation effect, especially, when current roller diameter, quality are larger, roller is due to static friction effect stronger between roller, and torsional oscillation effect is more obvious, even cause the torsional deflection of roller, cause serious economic loss to enterprise.
Summary of the invention
An object of the present invention provides a kind of servo-control system can eliminating roller turn vibration when fine spining machine long vehicle starts.
Servo-control system of the present invention mainly comprises servo-driver, servomotor and programmable logic controller (PLC), servo-driver directly controls servomotor, servomotor is successively by connecting gear, reduction gearing, toothed belt transmission drives left hand front roller to rotate, simultaneously successively by connecting gear, tumbler gear, reduction gearing, toothed belt transmission drives right hand front roller to rotate, servo-driver is connected with programmable logic controller (PLC), programmable logic controller (PLC) receives starting signal simultaneously, to realize the closed loop controlling structure that servomotor rotates tailstock place front roller.
The control model of servo-drive system of the present invention is torque mode, is arranged on fine spining machine tailstock place.
Another object of the present invention is to provide a kind of method eliminating ring throstle roller turn vibration.
Described method, for install above-mentioned servo-control system additional at ring throstle tailstock place, is rotated the front roller of tail part and is given certain torque compensation, to realize eliminating roller turn vibration.
During driving, owing to there is larger stiction between front roller and rubber roll, and mair motor transmission is sent to the tailstock by headstock needs the regular hour, therefore roller turn vibration is the most remarkable, therefore, for realizing headstock and tailstock place roller rotary balance, during driving, servomotor works in mode at full capacity, gives tailstock roller with maximum torque compensation, then the stepped decline of live load, finally drops to about 30% ~ 50% steady operation of roller driving torque.
Servo-control system provided by the invention and method, effectively can eliminate the roller turn vibration at tailstock place, realizes headstock and tailstock rotary balance, can extend roller service life, prevent roller from rupturing; Equipment can be alleviated by the quiet load to dynamic process middle gear, extend its service life; Be conducive to minimizing equipment by quiet to mair motor load in dynamic process.
Accompanying drawing explanation
Fig. 1 is servo-control system block diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, a kind of servo-control system eliminating roller turn vibration comprises servo-driver 3, servomotor 4, programmable logic controller (PLC) 2, wherein servomotor 4 is by motor shaft 8 driven gear 11, gear 11 engages each other with gear 12 and is connected, gear 12 is connected with gear 14 by connecting axle 10, gear 14 drives the gear 17 on left hand front roller 6 by Timing Belt 19, finally realize the torque compensation of servomotor 4 pairs of left hand front rollers 6, gear train 11 and 12 and gear train 14 and 17 realize slowing down controlling jointly; Gear 12 engages each other with gear 13 and is connected, gear 13 is connected with gear 15 by connecting axle 9, gear 15 drives the gear 16 on right hand front roller 5 by Timing Belt 19, finally realize the torque compensation of servomotor 4 pairs of right hand front rollers 5, gear 13 realizes Rotation With Changing to effect, and gear train 11 and 12 and gear train 15 and 16 realize slowing down controlling jointly; Servo-driver 3 is connected with programmable logic controller (PLC) 2, and programmable logic controller (PLC) 2 is connected with fine spining machine starting signal system 1 simultaneously.
A kind of method eliminating ring throstle roller turn vibration, for above-mentioned servo-control system is arranged on the fine spining machine tailstock: during driving, programmable logic controller (PLC) 2 controls servomotor 4 by servo-driver 3 after receiving the starting signal that fine spining machine starting signal system 1 sends and operates at full capacity with torque mode, tailstock place two row front roller is given with maximum torque compensation by gear connected system, then the stepped decline of servomotor 4 live load, finally drop to about 30% ~ 50% steady operation of roller driving torque, to realize headstock and tailstock place roller rotary balance.When a failure occurs, programmable logic controller (PLC) 2 sends fault stop signal 7.
Roller turn vibration is conducive to the mechanical wave eliminated because roller turn vibration produces after eliminating; Roller service life can be extended, prevent roller from rupturing; Equipment can be alleviated by the quiet load to dynamic process middle gear, extend its service life; Be conducive to minimizing equipment by quiet to mair motor load in dynamic process.
