Description

The control circuit of Yarn break checkout gear

Technical field

The utility model relates to two-for-one twister, is specifically related to a kind of control circuit for double twist frame broken yarn detecting, is applicable to have the workshop of a large amount of two-for-one twisters.

Background technology

Yarn break checkout gear is for automatic broken yarn detecting ingot position signal on two-for-one twister.The Yarn break checkout gear used at present is single ingot Yarn break checkout gear, and internal main will be comprised of a LED lamp and a tongue tube, all needs to install a Yarn break checkout gear on each ingot, and a general two-for-one twister need be installed 256.Yarn break checkout gear only by be arranged on LED lamp on each ingot bright, go out to indicate the broken yarn state, current ingot bit number information can't be passed to the personnel that connect broken yarn exactly, need to manually go to ingot one an ingot ground to observe LED lamp state and judge whether broken yarn, so just need personnel from the tour of walking about of the first ingot to the 256 ingots.Long 17 meters of machine, having in the workshop of a large amount of two-for-one twisters, and personnel walk about time of making an inspection tour considerably beyond the actual time that connects broken yarn, have wasted a large amount of human resources, have increased human cost.

Along with the development of electronic information technology, the application of monolithic embedded microcontroller (MCU) is more and more extensive, how to use the function that MCU is powerful, realizes the functions such as coding, communications of single ingot information on two-for-one twister, has become the focus of current industry research and development.
