Problems solved by technology

[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 characteri

Embodiment

[0057] figure 1 It is a flowchart of the control method of the present invention. In step 101, set process parameters on the man-machine interface, and then transmit them to the DSP controller and the servo joint device respectively through the CAN communication module or the CAN bus module, so as to realize process parameter setting and storage.

[0058] In step 201, the DSP controller is connected with the main control computer through the RS485 communication module or the RS485 interface module, and sends a request to the main control computer to obtain the information of the spinning splicing spindle number, and the main control computer sends the joint The spinning position number information is sent to the DSP controller, so that the DSP controller can obtain the required piecing spinning position number information. Among them, the spindle position number information is mainly composed of information such as the positioning of the spinning spindle number, the splicing ...

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...
