Outer yarn rack device for automatically changing yarns

Abstract

The invention provides an outer yarn rack device for automatically changing yarns. A yarn feeding device is used in coordination with a host machine requiring yarn feeding; a plurality of yarn feedingmechanisms are sequentially arranged on the host machine along the horizontal direction; yarn rolls and spare yarn rolls are arranged at the front and back of the top of the yarn feeding mechanisms;the yarn feeding device comprises a vertically-arranged bracket and a closed guide rail formed in the top of the bracket; the guide rail respectively passes through the positions of the yarn rolls andthe spare yarn rolls at the top of the host machine when working; the yarn rolls are flexibly mounted on the guide rail and can move along the guide rail; and a yarn roll changing mechanism is further arranged on the guide rail. The changing yarn rolls are moved through the guide rail, and thus manual picking and placing operations are avoided, so that the potential safety hazard of picking and placing heavy objects at higher places is avoided, and the problem of damaging the health of a worker under long-term work is further solved; accordingly, the manual operation is liberated, the labor cost can further be reduced, the automation popularization rate of a production workshop is improved, and the full automation of yarn feeding operation is realized.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to an outer creel device capable of automatically changing yarns. Background technique [0002] The textile industry is one of the important light industries that are indispensable in modern times, and yarn is the most basic raw material in the textile industry. Through the processing of yarn, it can be made into different specifications of lines, which can be used for weaving and rope making , thread making, knitting and embroidery and other different textile crafts. [0003] The machinery for yarn processing in the modern textile industry includes yarn doubling frames, twisting machines, winding machines, etc. These devices usually include a main machine and a main yarn roll set on the main machine for yarn loading, and each main yarn roll is A spare yarn roll is set up, and the thread head of the spare yarn roll is connected to the thread end of the main yarn roll. When the yarn...
