1. A destacker unit for a destacking system such that a stack of objects each having a flange extending outwards along its perimeter is destacked in a predetermined direction by rotational motion of the destacker unit, wherein said destacker unit comprises:
a wheel unit having a rotation axis, said wheel unit comprising:
a lower surface for carrying the stacked objects, and
an inclined member located above the lower surface, the inclined member having an inclined upper surface defining an inclination and a bottom surface such that a distance between the inclined upper surface and the bottom surface increases around at least a part of a periphery of the wheel unit,
a connector part, engaging the wheel unit, the connector part defining a thread having an orientation, and wherein the orientation of the thread corresponds to the inclination of the inclined upper surface, wherein the inclination of the inclined surface is within +/−30% of a pitch of the thread, or within +/−20%, or within +/−10%, or within +/−5% of the pitch of the thread.
