Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0021] Example. A two-for-one twisting car breakage alarm method, characterized in that: the yarn is supported by a rotatable guide wheel on the main shaft, and rotates under the action of the yarn's own weight, tension and friction; the light-through hole on the main shaft and the guide wheel The guide wheel overlaps once every revolution, that is, the light passes through the main shaft once; when the yarn breaks, the guide wheel stops rotating, and the cycle process of "light-shielding" in the main shaft stops; by detecting the "light-shielding" in the main shaft Whether the shading cycle is stopped to determine whether the yarn is broken, and to activate the sound and light alarm in the event of a broken end. The cycle process of "light-passing-light-shielding" in the detection spindle is compl...

Abstract

The invention discloses a method for two-for-one twisting vehicle web break alarm, which is characterized in that a rotatable guide wheel on a principal shaft supports yarn and rotates with the action of self weight, tensile force and frictional force of the yarn; light through holes on the principal shaft and the guide wheel coincide once when the guide wheel rotates for a circle, which means the principal shaft let light in once; when web break happens to the yarn, the guide wheel stops revolving, light-in-light-shading cycle process in the principal shaft stops; whether web break happens to the yarn is confirmed by detecting whether the light-in-light-shading cycle process in the principal shaft stops or not and a combined aural and visual alarm is initiated when web break is confirmed. In the invention, on the precondition of not increasing the risk of yarn web break, break point and break point position of the yarn can be found in time, manual handling can be prompted in time and product quality can be ensured; in addition, working stress and labor intensity can be reduced and production efficiency can be improved.

Description

technical field [0001] The invention relates to a method and device for alarming the end of a two-for-one twisting machine, belonging to the technical field of textiles. Background technique [0002] The length of the two-for-one twisting car used in the textile printing and dyeing industry is about 20 meters. There are 256 spindles on each two-for-one twisting car. When the two-for-one twisting car is working, the yarn on each spindle needs to be twisted and then wound onto the spool. Usually one worker needs to manage about 10 two-for-one twisters. In the process of winding the spindle on the spool, there will inevitably be thread breakage. If it is not found or handled in time, the product quality will be affected. But to find breakpoint in time among numerous yarns, this just needs worker to keep high tension state all the time in work, and its work tension degree and workload are very big, and work efficiency is also low. And in the existing decapitation automatic ala...
