Rotational Transport Assembly

      Disclosed is a rotational transport assembly for transporting
hardfile disks through a two-spindle testing process.

      The Figure is an isometric view of the rotational transport
assembly 10, which includes, as major subassemblies, a base 12, a
drive motor 14, a support structure 16, a lift unit 18, a swivel
connector 20, and a disk handling unit 22.  Drive motor 14 is
connected to support structure 16 by means of a belt drive mechanism
(not shown) within base 12, so that the rotation of drive motor 14
produces a pivoting movement of structure 16 as indicated by arrow
24.  Various electrical lines and pneumatic hoses (not shown),
associated with other movements and functions of the tranport
assembly 10, are brought into the support structure 16 through a
conduit tube 26, which is fastened to an upper housing 28 of swivel
connector 20.  This housing 28 pivots freely on support structure 16,
allowing pivoting movement of the structure 16 without twisting and
rubbing the lines and hoses.  Also, to prevent twisting of these
lines and hoses, the rotational movement of support structure 28 is
limited to 360 degrees or less.

      Within support structure 16, lift unit 18 moves upward and
downward, as indicated by arrow 30, along columns 32.  Disk handling
unit 22 extends outward from lift unit 18, holding a first disk 34
facing upward and a second disk 36 facing downward.  Each disk is
held by means of three grippers 38, mounted on pneumatic actuators
40.  An actuator 40 moves the grippers 38 holding downward-facing
disk 36 apart, releasing the disk.  This actuator 40 also moves its
associated grippers 38 apart and again together to pick up a single
disk, which becomes a downward-facing disk in the unit 22.  Disk
handling unit 22 is also rotated 180 degrees about the axis of its
shaft 42, as indicated by arrow 43, so that the positions of disks 34
and 36 are reversed.

      The hardfile disk testing station also includes an input hub
44, an output hub 46, a first spindle 48, and a second spindle 50.
The hubs 44 and 46, each provide a space on which a single hardfile
disk is temporarily stored, being shaped to fit within a central hole
in the disk.  The spindles 48 and 50 each rotate a disk being tested
through a...
