Problems solved by technology

[0005] A disadvantage of the background art lies especially in the fact that if the spinning entry is performed manually by the operator, it is time-consuming and also laborious, since current machines have dozens of work stations arranged in a row next to each other
Another disadvantage is the fluctuating quality of the piecing device, which depends on the current state of the yarn end in the drawing tube
Another disadvantage is the high consumption of energy during the entry of a large number of spinning

Embodiment Construction

[0013] The method according to the invention for mass spinning of incoming yarns at a workstation of an air spinning machine will be described with reference to an exemplary embodiment of a workstation of an air spinning machine having: a pulling mechanism for the yarn the respective drives of the device for feeding the fiber to the spinning rotor in the spinning unit, which is located below the pulling mechanism of the yarn; and the vacuum compensator for the yarn length, which It is arranged between the yarn pulling mechanism and the yarn winding device. An air spinning machine comprises at least one row of identical workstations arranged adjacent to each other, but usually two parallel rows of identical workstations.

[0014] spinning unit 2 A fiber feeding device driven by a stepping motor is provided at its fiber inlet or more specifically the sliver inlet 20 , the stepper motor constitutes the fiber feeding device 20 separate drive. After the feeding device in the di...

Abstract

The invention relates to a method for yarn entry for mass spinning at work stations of a rotor spinning machine. When spinning stops at work stations, work station preparation for spinning entry is performed and subsequently at short intervals yarns are spun at the work stations at the same time in groups or singly. Each work station comprises a feed device (20) pushing fibers to a spinning rotor(2); the spinning rotor (21) is located in a spinning unit (2) under a draw-off mechanism (4) of the yarns (1); a compensator (6) for yarn length and a winding device for the yarns (1) are located above the draw-off mechanism (4). The invention also relates to the rotor spinning machine.

Description

[0001] This application is an invention with the filing date of the original application on May 13, 2016, the application number 201610314543.X, and the title of the invention "A method for entering a large amount of spinning yarn at a workstation of an air spinning machine and a device for performing the method" A divisional application of a patent application. technical field [0002] The invention relates to a method for mass spinning incoming yarn at a workstation of an open-end spinning machine, wherein after stopping the spinning entry at the workstation, preparation of the workstation for spinning incoming is performed and subsequently Yarns are spun simultaneously or in groups or individually at workstations within short time intervals, where each workstation includes means for feeding the fibers to the spinning rotor located at the yarn take-off mechanism In the spinning unit below, a compensator for the length of the yarn and a winding device for the yarn are arrange...
