ABSTRACT:
A device (10) for positioning a glass sheet or other generally rigid planar object (G), having a roller bed table (12) for supporting the object in a horizontal plane and an overhead device (14) carrying a first set of spaced apart arms (26, 28, 30, 32), each of which has a vertically acting cylinder (70) near a free end thereof, and a second set of spaced apart arms (20, 22, 24) near a free end thereof, each of which has a horizontally acting cylinder (48) near the free end thereof. Each vertically acting cylinder has a sheet edge contacting element (74) at the free end of its cylinder rod (72), and these edge contacting elements act as fixed stops during the positioning of the object. Each horizontally acting cylinder has a sheet edge contacting element (52) of the free end of its cylinder rod (50), and these edge contacting elements act as movable stops during the positioning of the object. The edge contacting elements of both the vertically acting cylinders and the horizontally acting cylinders can be retracted to positions above the sheet to permit the transferring of a sheet to, and from, the device. Each of the first arms is made up of two arm sections (60, 62) which are pivotably joined in an end-to-end manner, an inner section which is pivotably joined to the overhead device and an outer section which carries the vertically acting cylinder.
