Yarn collecting plate type broken yarn detection device of warping machine

Abstract

The invention relates to a yarn collecting plate type broken yarn detection device of a warping machine. Angle seats are fixed on two sides of a left vertical plate, a middle vertical plate and a right vertical plate in a frame; multiple layers of front yarn guiding plates and rear yarn guiding plates are arranged up and down at certain intervals; a support rod is arranged between every two layersof plates; a plurality of spacers and yarn guiding hooks are sequentially connected on each support rod in series; a hook supporting rod is arranged below each yarn guiding hook; a pair of photoelectric emitting heads and photoelectric receiving heads are respectively arranged on the front upper side of the left vertical plate and the front upper side of the right vertical plate through which each hook supporting rod passes; during warping, the yarn guiding hooks are lifted under the tension of yarns, light beams emitted by the photoelectric emitting heads irradiate on the photoelectric receiving heads, when the yarns are broken, the yarn guiding hooks fall down by means of dead weight, the light beams are blocked, a yarn breaking signal is sent out by the photoelectric receiving heads, when the yarns are drawn, the hook supporting rods rotate under the action of external force, the yarn guiding hooks are completely supported, needle threading and yarn drawing are facilitated, brokenhead detection and a wire collecting plate are integrated, and the device is compact in structure, sensitive, reliable, convenient to operate, economical, practical and novel in design.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a yarn break detection device for warping equipment. Background technique [0002] Warping is an important process of weaving. The warping machine is an important process equipment for textiles. The broken yarn detection device is a necessary function in the warping process. At present, the yarn broken detection device equipped with the warping machine is installed on the creel. Some are on the front of the car, and some are formed between the front of the car and the bobbin after the yarn is formed into pieces, using falling sheet contact, infrared photoelectric, and photographic detection methods, all due to the relationship between the detection position and the performance of the detection method. As a result, yarn breakage sometimes does not stop automatically, many malfunctions, yarn friction affects tension, long end-break signal output time, and high cost, etc., which aff...

[0002] Warping is an important process of weaving. The warping machine is an important process equipment for textiles. The broken yarn detection device is a necessary function in the warping process. At present, the yarn broken detection device equipped with the warping machine is installed on the creel. Some are on the front of the car, and some are formed between the front of the car and the bobbin after the yarn is formed into pieces, using falling sheet contact, infrared photoelectric, and photographic detection methods, all due to the relationship between the detection position and the performance of the detection method. As a result, yarn breakage sometimes does not stop automatically, many malfunctions, yarn friction affects tension, long end-break signal output time, and high cost, etc., which affect the quality of warping. It is urgent to develop a new type of warping yarn breakage detection device.
