Weft accumulator control system based on STM32 single-chip microcomputer

Abstract

The invention relates to a weft accumulator control system based on an STM32 single-chip microcomputer. The weft accumulator control system comprises a weft accumulator microprocessor, a weft storagemotor connected with the weft accumulator microprocessor, and a monitoring sensor; the weft accumulator microprocessor comprises a signal processing module, a communication module and a motor drivingmodule, the signal processing module comprises an STM32 chip, a minimum system, a weft accumulator switching circuit and a monitoring sensor receiving circuit; the weft accumulator switching circuit generates a switching signal and transmits the same to the STM32 chip and the minimum system of the weft accumulator microprocessor to control the start and stop of the weft storage motor and meanwhilecontrolling the positive and negative rotation of the weft storage motor; the monitoring sensor receiving circuit is used for receiving a signal of the monitoring sensor, transmitting the signal to the STM32 chip and the minimum system of the weft accumulator microprocessor for processing, and monitoring and adjusting the working state of the weft accumulator; and the weft storage motor is a brushless DC motor, and the monitoring sensor comprises a number of turns sensor, a weft yarn position sensor and a yarn breakage sensor. The system is high in response speed, moderate in cost and good incost performance.

Description

technical field [0001] The invention relates to the technical field of weft storage device control for rapier looms, in particular to a weft storage control system for rapier looms. Background technique [0002] The rapier loom is one of the important models of the shuttleless loom, and the weft feeder device is a key component of the rapier loom. It is particularly important to control the weft yarn tension in the weaving process of the loom to improve the quality of the fabric. With the rapid development of rapier looms and the continuous improvement of weft insertion speed, the related issues of weft yarn tension control are more important, and the widespread use of weft feeders has emerged as the times require. If the weft yarn is drawn directly from the bobbin, since the weft insertion occurs intermittently, the intermittent unwinding of the weft yarn and the continuous reduction of the unwinding radius of the bobbin will cause large fluctuations in the weft yarn tensi...
