Embodiment Construction

[0026] Since the main purpose of the present invention is to allow the monitoring device to automatically calculate the sensitivity matching the monitored yarn based on the data collected by the yarn sensor, it is necessary to introduce how to obtain the sensitivity first. The sensitivity mentioned here is a threshold for judging the state of yarn movement. If the sensing value of the yarn sensor is lower than the sensitivity, the yarn is considered to be in a stopped state, otherwise, the yarn is considered to be in a moving state. The monitoring device Based on this, the yarn movement state can be accurately judged.

[0027] Such as figure 1 It is the yarn movement state collected by the yarn sensor under ideal conditions. Under the ideal situation of no environmental interference, smooth and uniform yarn, stable speed, and stable optical / electric conversion device, the sensor data collected by the sensor has only two values, one is the sensor value when the yarn stops (point A...

Abstract

The invention discloses a device for monitoring the yarn moving state and a monitoring method for the same, having the objective that the sensitivity matched with the monitored yarn is automatically calculated out according to the data collected by a yarn sensor by the monitoring method. The invention has the technical solution that the device is electrically connected with a textile machine and used for monitoring the yarn moving state; the monitoring device comprises a controller connected with a memory by a data line interface, the memory may be an external memory or integrated in the controller and connected with a display driver by a data line interface, the display driver is connected with a display module; the controller is connected with a group of yarn sensor at the input end of the textile machine by a serial port bus; the textile machine can transmit the running state of the machine to the controller by a pulse signal line and a zero signal line, the stop signal is transmitted to the textile machine by a controller through a switch. The invention is suitable for the textile machine for producing the textile by using the yarn as the raw material.

Description

Technical field [0001] The invention relates to a device and a monitoring method for monitoring the movement state of yarns. It is suitable for most textile machines that use yarn as raw material to produce textiles, especially knitting machines. Background technique [0002] At present, in the working process of the textile machine that uses yarn as the raw material to produce textiles, the yarn as the raw material may be blocked, broken, or entangled at an unpredictable moment in the production process. At this time, the textile machine It will not be possible to process the raw materials according to the pre-programmed conditions. If the machine is not shut down in time to eliminate the fault, it will directly lead to defective products. Therefore, the purpose of the yarn monitoring device is to monitor the running status of the yarn and the machine during the production process to evaluate whether the current yarn status is normal and whether it meets the pre-set production s...
