Abstract

A yarn breakage monitoring device, comprising a ring spinning machine (1), a blowing and suction cleaning apparatus (4), and a yarn breakage detection device. The yarn breakage detection device comprises a spindle position mark, a wireless camera (31), a fixed member (32), a monitoring terminal and a yarn breakage position determination system.

After the yarn is broken, the temperature of the part is lowered, and the sensor converts the temperature value into an electric signal and sends it to the signal processor, the signal processor. Signals can be sent within 8 to 16 seconds. Although such a sensor element is small and small in size, it is costly to configure one sensor per spinning position, and it is necessary to manually patrol back and forth, and the labor intensity is high.

The Chinese Patent Publication No. CN202450212U is a yarn breakage detecting mechanism for a counter-pressure pneumatic spinning machine, comprising a plurality of steel collars mounted on a steel collar plate and a traveler wire disposed on each steel collar track, the steel collar plate being installed Corresponding to each of the steel collars and the pressure sensor for detecting the change of the travel of the traveler, the air nozzle is disposed opposite to the pressure sensor, the central axis of the air nozzle is tangent to the outer peripheral surface of the steel collar, or the central axis of the air nozzle The top surface of the ring runway coincides and the output of the pressure sensor is connected to the processing circuit. The non-contact detection is used to obtain the rotation frequency of the change of the travel of the traveler. Although it has the characteristics of reasonable structure, convenient installation, accurate detection and rapid detection reaction, the cost of the gas nozzle and pressure sensor for each spinning position is still the same. It is very high and requires manual round-trip inspections, which is labor intensive.

The Chinese patent publication number CN202705616U is a siro-spinning yarn breakage detection device. A photoelectric switch is mounted on each spindle, and the CMOS camera is mounted on the patrol car. When the car is inspected, the CMOS camera acquires image signals. The image information including the yarn and the surrounding objects is converted into voltage signals of different values, and the image information transmitted by the camera is analyzed and processed by the processor to determine whether the two yarns are intact. If the yarn is intact, the processor control relay drives the green warning light to be on, and at the same time, by controlling the motor drive circuit, the driving carriage is driven to continue to detect the yarn on the next spindle; if a single yarn or a broken yarn is detected, the tour trolley stops and cuts off. Single yarn, at the same time, the red warning light is on and issued to remind the driver to handle the problem. However, the working area of the yarn factory is large and the noise is loud. The driver often does not see the warning light and can not hear the alarm sound. The inspection intensity is still not effectively alleviated. If the driving tour car detects a single yarn or a broken yarn, the tour vehicle will stop. If the driver does not handle it in time, the tour vehicle will not be able to continue the yarn break detection. There is also a patrolling movement detection method, in which a runway is installed on the front side of the steel collar plate, a magnetoelectric sensor is mounted on the runway, and the rotating signal of each frayed bead ring is sensed by the moving magnetoelectric sensor, and the signal is transmitted through the wire. Into the central processor to detect the spinning break of each spindle, but because the runway is installed at the front of the steel collar, the presence of the runway is inconvenient for manual operation and cleaning work. These two types of roving cars not only increase the manufacturing and maintenance costs of the car, but also occupy the space of the spinning machine, and additionally increase the energy consumption for driving the car.

A yarn breakage detecting device of the Chinese Patent Publication No. CN103911702A, comprising a ring spinning machine, a blown air cleaner, and a yarn break detecting device, characterized in that: the yarn breakage in the yarn detecting position The detecting device is composed of a spindle position mark, a wireless camera, a fixing member, a monitoring terminal and a yarn break position determining system, and the wireless camera is mounted on the blower cleaning vehicle through a fixing member, and the wireless camera is facing the yarn of the yarn position. At the detecting position, the spindle position mark is set at the yarn detecting position of the yarn position, and the yarn break position determining system is based on the real-time image of the yarn detecting position taken by the wireless camera and the yarn detecting portion when the yarn is not broken. The standard image comparison judges whether the yarn at the yarn detecting end is broken, and at the same time, the spindle position is recognized by the spindle position mark, and the judgment result signal is output to the monitoring terminal. Although the invention has real-time monitoring of yarn break position, area and number of broken ends, no need to manually patrol back and forth, reduce personnel reactive inspection, greatly reduce labor intensity, reduce labor cost, and wide range of monitoring, and can be based on The distribution of the number of broken ends is centralized, and there is no need to stop the process when it is concentrated. It does not affect the manual operation and cleaning and is convenient and convenient. However, when the scene is dim, the speed of the suction and cleaning is faster, the real-time image of the camera is taken. The quality will drop, which will affect the judgment of whether the yarn at the yarn detection is broken.
