Standby yarn winding device for automatic jointing of ring spun yarns

Abstract

The invention relates to a standby yarn winding device for automatic jointing of ring spun yarns. The standby yarn winding device comprises an air blowing and yarn winding device, a standby yarn unwinding device and a yarn conveying and flexible traction device; the air blowing and yarn winding device can stably wind standby yarns onto a broken yarn bobbin; the standby yarn unwinding device can control the output length and speed of the standby yarns; and the yarn conveying and flexible traction device is assembled at the tail end of an industrial robot and used for completing conveying of the standby yarns and flexible holding and traction of the standby yarns. The invention provides a stable and reliable standby yarn winding device for a yarn guiding and jointing mode in automatic jointing, and solves the problems of unstable yarn winding and low success rate in an existing yarn guiding and jointing technology.

Description

technical field [0001] The invention relates to a spare yarn winding device for automatic jointing of ring spinning spun yarns, belonging to the technical field of automatic jointing of ring spinning spun yarns. Background technique [0002] Spinning is an important process in the spinning process. The interruption of yarn in the spinning process will directly affect the production efficiency of spinning. At present, the work of broken yarn jointing is still done manually by a large number of skilled car workers. The goal pursued by the yarn industry. [0003] The existing automatic jointing methods at home and abroad are mainly divided into two types: yarn-finding joint and yarn-leading joint. Among them, the yarn-finding joint finds the broken end on the original broken yarn bobbin to complete the jointing action. Spinning frame automatic splicing robot and its method"; Yarn leading splicing saves the action of finding broken ends on the original bobbin, and uses a spare ...

AI Technical Summary

Problems solved by technology

[0004] (1) The yarn winding device of the spare yarn winding device in the existing yarn drawing and jointing technology is unstable, and it is difficult to successfully wind the spare yarn on the broken bobbin, resulting in the inability to continue the subsequent jointing action

[0005] (2) The existing methods and devices for threading joints use a rigid mechanism to hold and pull the yarn. In the actual jointing process, it is easy to cause unstable holding, excessive pulling to cause the yarn to be broken, or the yarn to be broken due to insufficient pulling. Problems such as kink under its own twist;

[0006] (3) The existing yarn leading and jointing methods and devices are difficult to solve the characteristics of yarns that are easy to flutter, untwist, and break easily. During the jointing process, the quality of the yarn is different, and the phenomenon of yarn breakage will occur again, resulting in a decrease in jointing efficiency
