Abstract

Fig. 1 illustrates a conventional vacuum pickup head with a chamfered pilot 4, vacuum pickup cups 5 supported on rigid vacuum supply pipes 9 and an air cylinder 6 for pilot actuation. Pilot 4 is shown with a slightly misaligned disk 7. In this condition, engagement of the pilot and disk at the interference point 8 often causes binding and failure of the pilot to enter the disk center opening. This condition results in either shutdown of the system or nonuniform stacking of the disks. Fig. 2 shows the same design as Fig. 1 except for the use of flexible vacuum supply tubes 9'. As the pilot 4 is extended toward the disk, the flexible supply tubes yield to permit the pilot 4 to extend into the central opening and properly align disk 7.
