THE PRESENT INVENTION RELATES TO A VACUUM PAD DEVICE (10, 30) USED IN A VACUUM TRANSPORT SYSTEM. THE PAD DEVICE (10, 30) INCLUDES A HOUSING (11), A PAD UNIT (12) CONNECTED TO THE HOUSING (11) THROUGH A BALL JOINT (18) SUCH THAT THE PAD UNIT (12) IS ROTATABLE, AND A PISTON (13) ARRANGED IN THE HOUSING (11) AND CONTROLLING THE ROTATION OF THE PAD UNIT (12). THE PAD UNIT (12) IS BONDED TO AN OBJECT AT A DESIRABLE ROTATION ANGLE, AND CONTROLLED SUCH THAT THE ROTATION ANGLE IS FIXED BY THE MOVEMENT OF A PISTON (13) OPERATING VIA COMPRESSED AIR. CONSEQUENTLY, THE OBJECT CAN BE TRANSPORTED IN AN ACCURATE AND SAFE MANNER. PREFERABLY, THE VACUUM PAD DEVICE (30) OF THE PRESENT INVENTION FURTHER INCLUDES A VACUUM PUMP (31) ARRANGED IN THE HOUSING (11) USING THE PISTON (13). (FIGURE 3)
