Embodiment 1

[0025] This embodiment is used to provide a kind of quality monitoring method of false twist yarn, as figure 1 Shown, described monitoring method comprises the steps:

[0026] S1: Obtain the speed of each false twisting needle in real time;

[0027] Since there is a certain correspondence between the twist of the false twisted yarn and the rotational speed of the false twisting needle, the twist value of the false twisted yarn can be calculated according to the rotational speed of the false twisting needle through table lookup and correction coefficient, and then the quality of the false twisted yarn can be obtained. Therefore, after acquiring the rotating speeds of each false twisting needle in real time, the monitoring method of this embodiment also includes judging the quality of the false twisting yarn corresponding to the false twisting needle, such as figure 2 As shown, specific steps may include:

[0028] S11: For each of the false twisting needles, judge whether the...

Embodiment 2

[0044] This embodiment is used to provide a quality monitoring system of false twisted yarn, such as Figure 4 As shown, the monitoring system includes:

[0045] The rotational speed sensor 1 is used to collect the rotational speed signals of each false twisting needle in real time. The rotational speed sensor 1 is fixedly installed near the false twisting needle through a bracket, and the rotational speed sensor 1 can be a photoelectric sensor or a Hall sensor, and the rotational speed sensor 1 can accurately detect the rotational speed signal of the false twisting needle. A monitoring system can include multiple speed sensors 1 at the same time, and can monitor the quality of multiple spindles of false twisted yarn at the same time, greatly saving labor costs.

[0046] The central display control unit 2 is communicatively connected with the rotational speed sensor 1, and is used to judge whether the rotational speed corresponding to the rotational speed signal satisfies the...

Abstract

The invention relates to a quality monitoring method and monitoring system for false-twisted yarns. The monitoring system comprises a rotating speed sensor and a central display control unit. A rotating speed sensor is used for collecting rotating speed signals of all false twisting needles in real time, a central display control unit judges whether the rotating speed corresponding to the rotating speed signals meets a preset condition or not, if not, false twisting yarn corresponding to the false twisting needles is cut off, and then based on the corresponding relation between the rotating speed of the false twisting needles and the quality of the false twisting yarn, by monitoring the rotating speed of the false twisting needle in real time, the quality of the false twisting yarn can be monitored in real time, the monitoring quality is accurate, when the rotating speed does not meet the preset condition, the false twisting yarn corresponding to the false twisting needle is cut off in time, spindle stopping is in time, the defective rate can be remarkably reduced, and materials are saved.

Description

[0001] This application is a divisional application of a patent application entitled "A Quality Monitoring Method and System for False Twist Yarn". The original application date was February 22, 2017, and the application number was 201710095671.4. technical field [0002] The invention relates to the technical field of textile false-twisted yarn quality monitoring, in particular to a quality monitoring method and monitoring system of false-twisted yarn. Background technique [0003] In the production process of false twisted yarn, it is necessary to monitor the twist change of false twisted yarn and whether broken yarn occurs to prevent defective products. In the prior art, the quality monitoring of false-twisted yarn is usually carried out by manual timing sampling method, which cannot be monitored in real time, and requires manual real-time monitoring of the false-twisted machine. The method of manual sampling monitoring is very dependent on the responsibility of the worke...
