The collective doffing driving device has the advantages of being low in price and high in operation efficiency and reliability.
Description
Technical field
The utility model relates to integral doffing device of ring spinning frame, belongs to especially the improvement of integral cosine doffing device driving mechanism.
Background technology
Along with the raising of textile machine automaticity, increasing ring throstle all has been equipped with integral cosine doffing device, and doffing device has not only reduced workman's labour intensity like this, and has greatly improved labor productivity.Present integral doffing device of ring spinning frame all is liftings of being removed to drive its miter arm by the servomotor of servo controller control by speed change gear, finish collective doffing, on the one hand since servomotor exist maintaining and very bother: on the other hand because the price of servomotor and servo controller thereof is all comparatively expensive, so that whole equipment cost and operation expense increase substantially.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides that a kind of cost is low, working service collective doffing drive unit easily.
The technical scheme that its technical problem that solves the utility model adopts is: the collective doffing drive unit, comprise driving the lift drive shaft of integral cosine doffing device miter arm, described lift drive shaft and threephase asynchronous are in transmission connection, axle head at threephase asynchronous is provided with angular displacement sensor, this angular displacement sensor feeds back to controller with angular displacement signal, the control signal of controller is sent into the frequency converter that links to each other with three phase mains, the output of frequency converter is electrically connected with threephase asynchronous, described threephase asynchronous is by being loaded on the motor synchronous belt wheel of its axle head, be loaded on driven synchronous pulley on the lift drive shaft and synchronous cog belt and lift drive shaft and mutually be in transmission connection, described threephase asynchronous is with brake apparatus.
Described angular displacement sensor is rotary encoder, can also or be rotary transformer for optical disc.
Owing in said structure, having adopted frequency converter and threephase asynchronous, not only improved the running efficiency of prime mover, decrease equipment cost, and have easily characteristics of working service, realized the inexpensive and high reliability of driving mechanism.Also owing to having adopted the half-closed loop control system that comprises controller, frequency converter, threephase asynchronous machine and sensor, improve control accuracy and accuracy, satisfied more reliably the performance requirement of integral cosine doffing device.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structure principle chart of the utility model collective doffing drive unit;
Fig. 2 is motor, the sensor assembly connection figure of collective doffing drive unit shown in Figure 1.
The specific embodiment
In Fig. 1, the integral doffing device of ring spinning frame miter arm is driven by lift drive shaft 7, to finish collective doffing, one end of lift drive shaft 7 axles is equipped with driven synchronous pulley 6, motor synchronous belt wheel 8 is housed on the output shaft of threephase asynchronous 4, between two synchronous pulleys 6,8, be in transmission connection with synchronous cog belt 5, be provided with angular displacement sensor 9 at the axle head of threephase asynchronous 4.As shown in Figure 2, angular displacement sensor 9 is placed on the sensor mandrel 10, sensor mandrel 10 is fixed in the axle head of threephase asynchronous 4 output shafts, and angular displacement sensor 9 is installed on the sensor stand 12 by vibration-damping sheet 11, and sensor stand 12 is fixedly connected with motor cabinet 13.Described angular displacement sensor 9 adopts rotary encoders, the adverse effect to encoder that causes with the circular runout when eliminating motor rotation of flexible damping pad 11.Be installed on threephase asynchronous 4 on the motor cabinet 13 with brake apparatus, its model is NYUBPEJ100L2A(B5), power 3KW.Angular displacement sensor 9 feeds back to controller 1 with angular displacement signals such as the rotation direction of threephase asynchronous 4 output shafts and amounts of spin, thereby forms the half-closed loop control system that can satisfy reliably the collective doffing requirement.Controller 1 adopts the programmable controller (PLC) of Siemens S7 one 200 systems, the control program that this programmable controller presets according to collective doffing technique and the feedback information of angular displacement sensor 9, control the frequency converter 3 that links to each other with three phase mains, 3 instructions according to controller 1 of frequency converter, the power supply that has appropriate frequency and voltage to threephase asynchronous 4 outputs, thereby the rotating speed of control threephase asynchronous 4, turn to and amount of spin, accurately to drive the lifting of integral cosine doffing device miter arm by motor and lift drive shaft, finish and pull out spool, pipe doffs, pipe uses leisure moments, the actions such as dress blank pipe.Programmable controller is also in time being controlled the brake apparatus of threephase asynchronous, with timely brake and the accurate location of realizing motor.Being connected with on the dc terminal of frequency converter 3 can device 2 by letting out of forming of chopper and resistance, thus protection threephase asynchronous 4 and frequency converter 3 sharply changes at the motor output speed, unlikely damaged during brake apparatus work.
Above-mentioned angular displacement sensor is not limited to rotary encoder, can also be the corresponding sensor such as optical disc or rotary transformer; The transmission connection method of threephase asynchronous and lift drive shaft except Synchronous Belt Drives, can also adopt the corresponding mechanical drive modes such as gear pair; Angular displacement sensor 9 can also be arranged on the relevant positions such as lift drive shaft 7, to detect its angular displacement except being arranged at motor shaft end.These conversion all should be considered as falling in the protection domain of the present utility model.
