Abstract:
1. An apparatus for grasping glass plates, the glass plates having a size of several square meters, in a contactless manner, having the following features: a) at least one oscillatory, rectangular, oscillating plate having at least one oscillation generator, wherein the four corners of the oscillating plate are each formed by a square sub-surface, and wherein each of these sub-surfaces has protrusions at its four corners, and wherein the sub-surfaces are connected together by crosspieces, b) each sub-surface has a central opening for receiving a suction pipe, installed on the upper side, for the suction extraction of air, c) provided on the underside of each sub-surface is a circular cutout which is connected to the central opening, d) the oscillating plate is connected to a central damping joint, which can pivot to all sides about a central attachment, via four connecting beams which are each secured to the suction pipe of a sub-surface via a holding ring and are brought together in the center of the oscillating plate, e) the central damping joint is connected to the central attachment in order to decouple an oscillation from the at least one oscillation generator, and f) a distance sensor for controlling a servo drive for moving the oscillating plate in the direction of the glass plate is accommodated in at least one suction pipe.
