The invention relates to a device for loading and unloading optical workpieces, for an optical machine. The device comprises a loading arm (24) which is pivotally driven about an axis (A) and is pivoted in controlled movement sequences on the optical machine between a workpiece magazine (26, 28) and the operating position. The outer end of the loading arm is provided with a device (30) for receiving and placing workpieces. According to the invention, the swivelling axis of the loading arm is the central axis of a spindle (40) which rotates in both directions of rotation (D<+>, X<->) and which can be driven linearly in a lifting motion in both axial directions (X<+>, X<->) by means of drive elements, as well as guided in guide elements in a rotating and displacing manner. The loading arm (24) is fixed to the spindle. |
