A control method for a section warping machine

Abstract

The invention relates to a control method of a sectional warping machine. The method comprises the steps that a positioning control module, a speed control module and a tension control module are included, the positioning control module detects position information of a shaft through a shaft encoder on a drum shaft, and a central controller controls the rotation speed of a control servo motor according to the position information; the speed control module detects speed information through a thickness measuring sensor and the shaft encoder, the linear speed of warping is calculated according to the speed information, the linear speed is compared with a preset linear speed, and according to a numerical value obtained after comparison, the rotating speed of a direct-current drum motor is controller by triggering a pulse module. According to the method, accurate positioning and displacement and automatic adjustment of speed and tension can be achieved, fluctuation of yarn tension is lowered, and the phenomenon that due to the fact that warp yarns are mutually wound into knots and the pressure is unbalanced, the yarn quality is affected is avoided.

Description

technical field [0001] The invention relates to a composition system of a warping machine, in particular to a control method of a section warping machine. Background technique [0002] The high-speed electronic sectional warping machine is widely used in the textile industry for the sectional warping before weaving of cotton, yarn-dyed, woolen, silk and various chemical fiber filaments, and the role of the sectional warping machine The spun yarn is pulled out from the creel and wound into the warping machine drum sequentially through the warping table. When it is wound to a certain length, the spun yarn is cut, and then the spun yarn is wound on the reeling machine. [0003] Existing section warping machines use slip motors or frequency modulation motors as the power source for driving the drums, and most of the speed adjustments use electrical speed control devices. For the frequency modulation motor, it takes a long time to brake the drum; for the slip motor, the torque i...

AI Technical Summary

Problems solved by technology

For the frequency modulation motor, it takes a long time to brake the drum; for the slip motor, the torque is small at low speed, and the energy consumption is large; and the above-mentioned electric speed control device is huge in equipment, the number of electrical components is large and the circuit is complicated, and the electrical control Most of the warping machines adopt manual speed regulation, which cannot realize automatic constant speed, and the speed control accuracy is not high, which seriously affects the quality of warp yarn

In the winding process of the section warping process, each warp yarn is in the yarn feeding process, due to the uneven tension control of the warp yarn, the warp yarns are entangled with each other and cannot be woven, which affects the warping effect
