Abstract

The invention discloses a single-spindle automatic doffing device and doffing method and a spinning machine adopting the doffing device, and aims to overcome the defects of a doffing machine of an existing rotor spinning machine, an existing vortex spinning machine or an existing automatic winder. According to the technical scheme provided by the invention, the single-spindle automatic doffing device is arranged above the cone yarn horizontal plane of each spinning unit of the spinning machine. The single-spindle automatic doffing device is provided with a cone yarn push rod, a yarn grabbing arm and an empty tube warehouse. When the single-spindle automatic doffing device is in a waiting state (no doffing), the single-spindle automatic doffing device is located above the cone yarn horizontal plane. The single-spindle automatic doffing device has the beneficial effects that under the condition that each spinning unit does not stop spinning, each single-spindle automatic doffing device realizes that each spinning unit simultaneously performs independent doffing, empty tube placement and tail yarn remaining work, and the spinning units do not influence one another, so that the doffing efficiency is improved; and moreover, the space is saved, and the device is more friendly to operators.

Description

technical field [0001] The invention relates to a textile machine, especially a package doffing device of an airflow mode, a vortex spinning machine and an automatic winding machine, and a method for doffing, placing an empty tube and leaving a tail of each spinning unit. Background technique [0002] As a new type of high-efficiency spinning machine, air spinning machine and vortex spinning machine are more and more favored by spinning mills due to their yarn delivery speeds up to 300 m / min and 550 m / min respectively. The produced yarn is wound on the empty paper tube at high speed to form a bobbin. In order to realize automatic and intelligent doffing work, the current air spinning machine and vortex spinning machine adopt automatic doffing machine. Each side of the machine adopts one or more doffers, generally not more than 4, to cruise between the spinning units on each side, once the bobbin of a spinning unit reaches the specified length (full bobbin) ), the doffing m...
