Abstract
In a device and method for lifting magnetizable carrier particles from a mixture of toner particles, a cover of a collecting element interface device is arranged such that it can be rotated around a stator with a magnet. The cover comprises a spiral that, given rotation of the cover, conveys the carrier particles in an axial direction.
Claims30
A device for lifting magnetizable carrier particles, comprising:
- a collecting element having a cover which is rotatable around a stationary stator;
- the stator comprises at least one magnet having a pole arranged relative to the cover such that the magnet's magnetic field attracts ferromagnetic carrier particles that are located on a carrier at a distance of an air gap;
- and
- a surface of the cover comprises at least one screw-thread-like spiral which, given rotation of the cover, moves the carrier particles in an axial direction relative to the cover.
A method for lifting magnetizable carrier particles, comprising the steps of:
- rotating a cover of a collecting element around a stationary stator, and wherein the stator comprises at least one magnet having a pole arranged approximately radial to the cover and a magnetic field which attracts ferromagnetic carrier particles located on a carrier at a distance of an air gap;
- and
- providing a surface of the cover with at least one screw-thread like spiral so that, given rotation of the cover, the carrier particles move in an axial direction relative to the cover.
A device for lifting magnetizable carrier particles, comprising:
- a collecting element having a cover which is rotatable around a stator;
- the stator comprises at least one magnet arranged relative to the cover such that the magnet's magnetic field attracts ferromagnetic carrier particles that are located on an adjacent carrier;
- and
- a surface of the cover comprises at least one spiral which, given rotation of the cover, moves the carrier particles in an axial direction relative to the cover.
