Method and device for automatically and intelligently piecing ring-spun yarn broken ends

Abstract

The invention relates to a method and device for automatically and intelligently piecing ring-spun yarn broken ends. In a spinning machine, a combination of a broken ends detection system, a movable type automatic piecing machine, a ring traveller positioning and stop mechanism and a control system formed by a single-chip microcomputer or a PLC is adopted, wherein spinning end breaking signals of every single spindle of the spinning machine are detected in real time through a sensor of the broken ends detection system, and the spinning end breaking signals from the broken ends detection system are received by the single-chip microcomputer or the PLC control system; the spinning end breaking signals are processed by the single-chip microcomputer or the PLC control system and are sent to the movable type automatic piecing machine and the ring traveller positioning stop mechanism, the spinning end breaking signals are received by the ring traveller positioning stop mechanism, a ring traveller controlling the spindle position of the broken ends is stopped and positioned exactly in front of a steel collar ring rail, the movable type automatic piecing machine relates to the steps: receiving the spinning end breaking signals, automatically moving to the spindle position of the broken ends, controlling a spindle with the broken ends, unwinding and guiding a yarn of a spool, clamping the yarn in the ring traveler and a yarn guide, controlling the feeding speed of the guiding yarn, and piecing the yarn and a fiber strand which is outputted by a front roller or a yarn guiding roller of compact spinning together; the unmanned intelligent mechanical operation of piecing the broken ends is realized during the spinning process of the ring-spun yarn.

Description

technical field [0001] The invention relates to a method and a device for automatic jointing of ring spun yarns, in particular to a method and a device for automatic intelligent jointing of broken ends of ring spun yarns. Background technique [0002] In recent years, the textile industry employs a large number of people in production, labor costs increase, and corporate profitability is low. Improving the automation and intelligence of textile machinery is the work that textile technicians are studying. With the PLC program control technology, single spindle breakage of spinning frame The research and application of new technologies such as testing, and the automatic control of the ring spinning frame are getting higher and higher, but there is no solution to solve the jointing operation of the ring spinning machine stopper by using machines instead of humans. Contents of the invention [0003] In order to solve the above problems, an object of the present invention is to...
