Yarn connection device

Abstract

The invention relates to a yarn connection device. The device comprises a spool clamping hand part, a driving system I, a suction nozzle assembly, a negative pressure device, a driving system II, a magnetic fixing body, a driving system III, a yarn clamping hand part and an industrial robot; the driving system I is used for driving the spool clamping hand part to move along the X axis, Y axis andZ axis of the space rectangular coordinate system, clamp a spool, release the spool and rotate around the axis of the spool clamping hand part; the driving system II is used for driving the suction nozzle assembly to move along the X axis and the Y axis and driving the negative pressure device to generate negative pressure so as to suck a broken yarn end on the spool to a to-be clamped position; the driving system III is used for driving the magnetic fixing body to move along the X axis and Y axis so as to stir a steel wire ring to the designated position; the industrial robot is used for driving the yarn clamping hand part to clamp the broken yarn end, hang the broken yarn end at the steel wire ring, an air loop ring and a guide wire in sequence, put the broken yarn end into a front roller jaw of a spinning frame and loosen the broken yarn end. The yarn connection device can conduct yarn connection work of complex three-dimensional routes.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and relates to a yarn joining device, in particular to a device for automatically joining yarns after a spinning frame breaks. Background technique [0002] After the existing spinning frame breaks, the mainstream of the yarn splicing technology is to manually resplice the yarn, that is, the worker takes out the broken spindle, manually finds the broken end of the yarn, and then uses the traditional pinching method. , reconnect the broken thread and continue spinning. This technology requires high proficiency of workers, cumbersome operation, easy to pollute the yarn, and low automation level. Manually find the broken end of the yarn, and then connect it, and the error rate is high. , The quality of the wiring is poor, the efficiency is low, and time is wasted. [0003] Patent CN105568455A discloses a broken wire automatic splicer, which pulls the front end of the broken wire back into ...
