Problems solved by technology

[0004] 1. Infrared light is a kind of invisible light. It is very difficult to align the light between the infrared transmitter installed at one end of the device and the infrared receiver installed at the other end of the device. It is not intuitive to debug the alignment of infrared light. , only with the aid of an additional indicator light set in the auxiliary circuit, such as the display of a light-emitting diode, can the infrared light alignment of the transmitter a

Abstract

The invention provides an automatic stop monitor for laser yarn broken warp/broken weft of spinner. The transmitter thereof adopts a semiconductor laser tube; the invention has the advantages of long service life, small volume, low consumption, high reliability and low cost and is characterized in that laser is a monochrome visual light, has good focussing characteristic, can spare the optical focussing system of transmitter and receiver and reduce the volume thereof and even miniaturize the optical focussing system; the laser between the transmitter and receiver can be directly and visually regulated to achieve optimal alignment; once the machine is mounted and fixed well, no light condensing is required again, thus realizing maintenance-free for a long time and providing great convenience for initial mounting regulation and daily maintenance service; and the invention has no disadvantage of light sources of infrared ray tube and light-emitting diode as well as scattered light or non-visual light, thus being an ideal yarn end cracking pick stopping automatic stopping monitor for multiple spinners.

Description

Technical field [0001] The invention relates to a warp and weft broken automatic stop monitor for a textile machine, in particular to a laser yarn broken warp and weft broken automatic stop monitor. technical background [0002] During the operation of the textile machine, once a certain warp thread or weft thread breaks, it must be stopped immediately, otherwise a large area of ​​gray cloth will be wasted. Usually, stoppers are used to monitor warp thread breakage, and the weft thread is automatically stopped by mechanical contact and collision with a probe; or non-contact self-stop that is blocked by infrared light. The non-contact self-stop method using infrared light has been gradually replacing the mechanical contact self-stop. [0003] Semiconductor infrared warp break and weft break self-stop monitors have been widely used in the above-mentioned textile machinery. Its advantages are long service life, small size, low power consumption, high reliability and low cost o...
