Embodiment 1

[0018] Such as image 3 As shown, R1 and R2 represent the rear roller and the front roller respectively, M1 and M2 are two image sensors for yarn fineness detection, M1 is used for open-loop control, M2 is used for closed-loop control, and is also used for spectrum analysis. The system mainly adjusts the speed ratio of R1 and R2 by controlling the servo S1 and S2 to achieve the purpose of adjusting the uniformity of the spun yarn. The analysis of the drafting device of spun yarn shows that its control system is mainly divided into four parts: mechanism, sensor, speed regulating mechanism and control mechanism according to its function realization. The overall structure of the control system is as Figure 4 As shown, the sensor collects the yarn fineness signal in real time, the UART is connected to the PC for the debugging stage, the VGA is used to display the image processing result, and the lower computer is used to receive the control signal of the FPGA processing result.

Abstract

An intelligent spun-yarn fineness random disturbance control device belongs to the field of novel textile machinery. The fineness of spun yarns changes in any time in production of the spun yarns, roller rotation speed can be adjusted to control evenness of the spun yarns, and a distance between a detection point and a point of roller rotation speed adjustment is very short, so that a high-speed real-time processing device is required. FPGA (field programmable gate array) serves as a system control core for processing fluctuation information of spun-yarn fineness signals, and the signals are used as signals for controlling rotation speed of a motor of a spinning frame later. The intelligent spun-yarn fineness random disturbance control device is also applicable to cotton carding, drawing and roving procedures in textile production.

Description

technical field [0001] An intelligent fineness random disturbance control device belongs to the field of new textile machinery. Since the fineness changes at any time during the spun yarn production process, the uniformity of the spun yarn can be controlled by adjusting the roller speed, and the distance between the detection point and the roller speed adjustment point is very short, which requires a high-speed real-time processing device. The present invention uses FPGA as the control core of the system to process the fluctuation information of the spinning fineness signal, and uses the signal as the control signal of the motor speed of the subsequent spinning frame. The same system is also suitable for carding, drawing and roving production in the textile production process. Background technique [0002] Spun yarn is a textile product formed by drawing dozens to hundreds of fibers. figure 1 It can be seen that the fineness of the spun yarn varies greatly, and the thicker...
