Guide wheel type yarn sensor based on force sensor and rotating speed sensor

Abstract

The invention discloses a guide wheel type yarn sensor based on a force sensor and a rotating speed sensor. The guide wheel type yarn sensor comprises the force sensor, the rotating speed sensor and aroller, and can simultaneously realize real-time monitoring of yarn breakage and yarn routing length. Specifically, the force sensor is used for detecting bending moment generated by a guide wheel under the action of spinning tension so as to measure the tension of yarns on the roller, thereby realizing monitoring of yarn breakage; and the rotating speed sensor is used for detecting the number ofturns of the roller on the guide wheel, and calculating the spinning length according to the perimeter and the number of turns of the roller.

Description

technical field [0001] The invention relates to the fields of textile thread tension detection technology and speed detection technology, in particular to a guide wheel type wire sensor based on a force sensitive sensor and a rotational speed sensor. Background technique [0002] Yarn detection is an important part of monitoring the state of yarn transmission. Yarn detection uses a roller-type yarn breakage sensor that uses the friction of the yarn against the roller to keep the roller in a rotating state. The tension can be used to judge whether the yarn is broken. The device has a simple structure and is easy to operate. [0003] However, its basic device has disadvantages: when the yarn breakage occurs, the operator does not find out the specific length of the usable silk thread passing through, so that the yarn may be different from the normal yarn in the later process of yarn twisting. Compared with the small number of strands, it affects the normal use and quality of ...
