Rotor spinning machine full automatic joint control method and device thereof

Abstract

The invention relates to a rotor spinning machine full automatic joint control method comprising seven steps: setting parameters, obtaining spindle number information, positioning walking, extending and retracting a manipulator, controlling the rotor speed, controlling the joint and resetting the manipulator in turn. The device realizing the control comprises a human-computer interface, a servo joint device, a rotor speed control device, a walking-positioning device and a manipulator control device which are respectively connected with a DSP controller by the transmission medium. The human-computer interface device is also connected with the servo joint device. The transmission medium comprises an RS485 module, a CAN module, an IO-signal and a high-speed I / O signal. The control method of the invention is simple; can realize the full automatic control of yarn joint operation, and overcome the deficiencies of low control precision, poor quality of joints and low efficiency of the existing semi-automatic joint spinning machine; and compensates shortcomings of larger power consumption, and low anti-interference and stability of the existing full automatic joint control system.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to a rotor spinning machine, especially a method and device for fully automatic joint control of the rotor spinning machine. Background technique [0002] At present, there are two types of joint control systems for rotor spinning machines: semi-automatic and fully automatic. In China, semi-automatic joint spinning machines are mainly used. The electric control system of the existing semi-automatic joint spinning machines is mainly controlled by solenoid valves, which has a high control accuracy. High, poor yarn joint quality and other shortcomings; while the existing foreign automatic joint control system has the characteristics of high control precision and good joint quality, and its joint control system mostly adopts software and hardware modular structure in design principles , and then connect through the CAN communication medium. The disadvantage is that the control system is designed...

[0002] At present, there are two types of joint control systems for rotor spinning machines: semi-automatic and fully automatic. In China, semi-automatic joint spinning machines are mainly used. The electric control system of the existing semi-automatic joint spinning machines is mainly controlled by solenoid valves, which has a high control accuracy. High, poor yarn joint quality and other shortcomings; while the existing foreign automatic joint control system has the characteristics of high control precision and good joint quality, and its joint control system mostly adopts software and hardware modular structure in design principles , and then connect through the CAN communication medium. The disadvantage is that the control system is designed with a modular structure, resulting in a complex overall system structure, high power consumption, excessive reliance on communication control, and low anti-electromagnetic interference performance and stability.
