Problems solved by technology

Although this method allows the rotor to be braked safely in the event of a mains voltage failure because the energy consumption of the control unit is rather small, the process is rather slow compared to braking via a load resistor

Embodiment Construction

[0021] figure 1 The work stations of an open-end rotor spinning machine 1 known per se are shown. An open-end rotor spinning machine of this type has a large number of identical workstations 2 arranged in a row next to each other, which are in each case equipped with a spinning device 3 and a winding mechanism 4 . The fiber sliver 6 fed into the spinning pot is spun into a strand 7 in a spinning device 3 by means of a spinning rotor, and the strand 7 is wound on a winding mechanism 4 to form a yarn bobbin 8 .

[0022] The opening rollers 15 prepare the fiber sliver 6 to be supplied to the spinning device 3 . The yarn withdrawal device 16 withdraws the finished spinning bundle 7 from the spinning rotor or spinning device 3 . Furthermore, the workstation 2 has in each case a yarn displacement device 18 which feeds the thread bundle 7 to the yarn bobbin 8 during traversing. As indicated, the winding mechanism 4 is in each case equipped with a creel 9 for rotatably holding the ...

Abstract

The invention relates to a workstation of an open ended rotor spinning machine having a rotor driver. The rotor driver is provided with a rotor motor and a control device, wherein the control device comprises a power supply circuit; the power supply circuit is provided with a voltage input, a voltage output and a power supply unit; the voltage input is at least connected to the power supply unit in the process of producing and operating the workstation; the rotor motor is connected to the voltage output; and the rotor motor can be operated as an electric generator in order to brake under the action of the control device. According to the invention, the workstation is provided with at least another electrical load required by producing and operating the workstation, the circuit is arranged for providing a braking electric energy output in the braking period of the rotor driver to at least another electrical load, and at least another electrical load is arranged for consuming the energy. The invention also relates to a method for operating the workstation.

Description

technical field [0001] The invention relates to a station for an open-end rotor spinning machine with a rotor drive having a rotor motor and a control device comprising a power supply circuit with a voltage input and a voltage output, said open-end rotor spinning The machine has at least one power supply unit, the voltage input is connected to the at least one power supply unit at least during the production operation of the station, and the rotor motor is connected to the voltage output, the rotor motor can be connected to Operates as a generator for braking by means of the control device. The invention also relates to a method of operating said work station. Background technique [0002] Open-end rotor spinning machines are already known in the prior art. Here the sliver is fed to the stations of the open-end rotor spinning machine. The sliver is first opened into individual fibers and conveyed by air flow to a rapidly rotating drum with inwardly inclined walls - the sp...
