Loading and unloading device for stone plate finishing machines - has two frames for swivel and translatory movement controlled by rack and pinion to allow turning and finishing of required plate side

摘要

The device has a first frame associated with the loading station of the machine and a second frame associated with the output station of the machine. The two frames are both mounted so that they can carry out translatory movements vertically upwards and/or downwards as well as rotations in two directions. The frames each comprise a structure with at least one rotatable shaft (58) having at least two rows of radial arms (74) protruding sideways and in the same plane. The frames have grippers (76) with suction heads and these are associated with at least one shaft and the arms. The shaft can be rotated by a rack and pinion device controlled by a piston cylinder unit. ADVANTAGE - The plate can be treated on one side or the other as required.
