Full-yarn automatic stop device of long spinning machine

Abstract

The invention discloses a full-yarn automatic stop device of a long spinning machine. A lower baffle plate is arranged above a yarn basket; a mounting hole is formed in the lower part of the lower baffle plate; a photo-electric sensing switch is fixed on the wall of the lower baffle plate and aside the mounting hole, and the front part of the photo-electric sensing switch penetrates the mounting hole; the back part of the photo-electric sensing switch is connected to a PLC (Programmable Logic Controller). When tube yarns are continuously accumulated in the yarn basket and reach to the height of the photo-electric sensing switch, the photo-electric sensing switch generates a signal, then the PLC is put through to send out the signal, a conveyor belt stops rotation, and an alarm signal light is turned on to remind workers that the yarn basket is full and remind the workers of replacing the yarn basket in time, so that the phenomenon that the tube yarns fall on the ground from the two sides of the yarn basket is eradicated completely and efficiently. The full-yarn automatic stop device of the long spinning machine can prevent the tube yarns from falling on the ground to form putty yarns when a yarn stacking worker does not itinerate in time, is not only convenient for the yarn stacking worker to operate, but also can realize normal conveying of the tube yarns, guarantees the quality of the yarns, is low in investment cost, convenient in processing, and wide in application range.

Description

Technical field: [0001] The invention relates to a component of a textile machine, in particular to a full-spun automatic stop device when a long spinning machine transports bobbins. Background technique: [0002] Ring spinning frame is a large-volume and wide-ranging equipment in the cotton spinning production process. It plays a vital role in the quality of the yarn. Ring spinning frame with collective doffing frame spinning machine is an important link for cotton spinning enterprises to improve labor productivity. Among the internationally advanced cotton spinning enterprises, almost all enterprises that can reduce the labor force of 10,000 spindles to less than 50 use spinning yarn The lead machine is equipped with collective doffing and fine connection as the main means. The realization of fine winding is firstly the single-machine automation of the spinning frame, and the key is to ensure the reliability and stability of the collective doffer. The advantages of match...
