Definitions

  • the present invention relates to an open-end rotor spinning device with a arranged in a rotor housing spinning rotor, wherein the rotor housing is covered by a lid member, and a pivoting device for opening and closing and a locking device for locking the lid member is provided, wherein in the lid member is a fiber feed channel and a Thread withdrawal channel is arranged.
  • the invention relates to a method for operating an open-end rotor spinning device having a rotating during spinning in a rotor housing spinning rotor, wherein the rotor housing is closed or opened with a lid member, and pivots the lid member for opening or closing the rotor housing with a pivoting device and is locked for locking the lid member with a locking device.
  • Open end rotor spinning devices with a locking device are well known in the prior art. So revealed the DE 10 2004 029 020 A1 an open-end rotor spinning device with a sensor device for monitoring the closing state of the rotor housing, wherein the rotor housing is closed by a cover element.
  • conclusions are drawn from the state of motion of the spinning rotor on the closed state of the rotor housing.
  • the lid member is released to open the rotor housing.
  • it is necessary that the rotor is still in operation with slightly open lid member, which is not possible on the basis of the prior art, without reducing the safety at work.
  • An open-end rotor spinning device with a spinning rotor arranged in a rotor housing is proposed.
  • the spinning rotor is preferably rotatably mounted in the rotor housing.
  • the rotor housing is covered by a cover element.
  • a fiber feed channel and a thread withdrawal channel are arranged in the lid member. According to the invention it is provided that the pivoting device and the locking device are interconnected.
  • the open-end rotor spinning device preferably has an opening roller, from which the sliver is dissolved into individual fibers. From the opening roller, the fiber sliver dissolved into individual fibers passes through the fiber feeding channel into the interior of the spinning rotor, where the individual fibers are spun into a thread. The thread is withdrawn through the thread withdrawal channel and wound onto a spool.
  • the cover element may need to be opened.
  • the cover element is repositioned by means of the pivoting device.
  • the pivoting device is preferably in operative connection with the cover element such that these two are moved or pivoted together. The position of the pivoting device and the cover element is monitored.
  • the pivoting device is connected in safe operation with the locking device, and this state is monitored.
  • the rotational speed of the spinning rotor is determined. Since individual spinning stations of the open-end rotor spinning device are preferably operated autonomously, it is concluded by the existing connection of the pivoting device with the locking device that the movement of the cover element takes place automatically, in particular without operating personnel. In a manual operation, however, first the connection between the locking device and the pivoting device must be disconnected. The separation of the locking device from the pivoting device is detected, whereupon the spinning rotor is stopped.

  • the linear drive is pivotally mounted. Despite the highly automated spinning stations, it is sometimes necessary to perform manual maintenance. In order to be able to open and close the cover element manually, it is advantageous if the linear drive is mounted so as to be pivotable.
  • the linear drive is arranged in a box frame, wherein the box frame is connected to the rotor housing.
  • the frame itself is preferably connected by means of a pivot joint with the linear application.
