Abstract
The utility model provides a leveling servo system for a drawing frame, which has strong anti-electromagnetic interference and high control precision and response speed. The leveling servo system of the drawing frame comprises a servo driver with a built-in leveling counting system, a servomotor connected with the servo driver and the drawing frame, a displacement transducer connected with the servo driver, a sliver feeding speed sensor and a sliver output speed sensor. Since the leveling counting system is directly built in the servo driver, the servo driver directly collects measurement signals and then counts out control quantity through the built-in leveling counting system to drive the servomotor, so as to reduce the signal errors brought forth by the multiple links of the original leveling controller which collects the signals and counts out the control quantity and then transmits to the servo driver, and improve the control precision and the response speed.
Description
Technical field
The utility model relates to a kind of electrical control field of textile machine, the neat and well spaced servo-drive system of especially a kind of drawing frame.
Background technology
At field of textiles, drawing frame need carry out monitoring calculation and control servomotor the feeding sliver, and the heavy rate of change of bar of sliver that makes output is little a lot of during than feeding.In the drawing frame running to neat and well spaced requirement be: the sliver speed of feeding should in time be adjusted according to feeding sliver weight rate, accomplishes the sliver weight substantially constant exported, and the big phenomenon of sliver deviation of weight fluctuation should not occur.
The drawing frame that uses is to control servo-driver by independent neat and well spaced controller to drive the servomotor realization at present.Its major defect is because low-voltage analog signals transmission course is subjected to electromagnetic interference and the not high reduction operating efficiency of response speed easily, also has complex structure, the not high shortcoming of control accuracy in addition.
The utility model content
The utility model provides a kind of anti-electromagnetic interference capability strong, the neat and well spaced servo-drive system of the drawing frame that control accuracy and response speed are high.
Realize the neat and well spaced servo-drive system of drawing frame of the utility model purpose, comprise the servo-driver that embeds neat and well spaced algorithm, with the servomotor that described servo-driver links to each other with drawing frame, the displacement transducer that links to each other with servo-driver, feeding sliver velocity sensor and sliver output speed sensor.
Described sliver output speed sensor adopts 1024 line relative value spindle speed encoders.This encoder can very accurately be measured the output speed of sliver, improves the precision of the neat and well spaced control of drawing frame.
The neat and well spaced servo-drive system of described drawing frame also comprises the man-machine interface that links to each other with described servo-driver, and described man-machine interface can be provided with and preserve the technological parameter of neat and well spaced algorithm in the described servo-driver.
Described man-machine interface is connected with servo-driver by the RS485 bus.
The servo-driver of the neat and well spaced algorithm of described embedding adopts the CR06660 AC servo driver of servotronix.
This servo-drive system is at the inner directly built-in neat and well spaced algorithm of servo-driver, directly gathering measuring-signal by servo-driver calculates controlled quentity controlled variable by built-in neat and well spaced algorithm and drives servomotor, reduce original neat and well spaced controller and gathered signal and calculate the too many levels signal errors that controlled quentity controlled variable is passed to servo-driver again, improved control accuracy and response speed; And neat and well spaced technological parameter can be provided with on man-machine interface, is transferred to servo-driver by the RS485 communications protocol, is used for built-in neat and well spaced algorithm and calculates.
Description of drawings
