Rotational Station for Two Sided Removable Media

      This article describes a flipping station for a double side
optical disk library.  The flipping station can be activated by the
picker or by a motor.

      The flipping stations are mounted in the storage receptacle
columns and flip the cartridge 180º  after receiving it from
the picker.  This mechanism could be implemented in 2 different ways.

Implementation #1 - This solution uses a servo motor which drives a
timing belt through a gear, which then causes a sleeve holding the
cartridge to rotate the required 180 degrees.  The cartridge holding
sleeve is mounted in a housing that contains a bearing, and shaft
that the sleeve rotates on.

The mechanism is described in the following Figures:

      Fig. 1 - picker assembly (1) containing the cartridge (2) is
shown traversing to the right positioning itself in front of the
cartridge holder sleeve (3).  The sleeve is shown mounted in the
housing (4), which also contains the shaft/bearing (5) system (at the
back) which allows the rotation.  Also shown is the servo motor (6)
with gear (7), and timing belt (8) which drives the shaft that causes
the rotation of the sleeve.  The sleeve also contains detent springs
which restrain the cartridge during the rotation function.

      Fig. 2 - picker assembly (1) has moved in front of the sleeve
(3).  Picker will next load cartridge (2) into the sleeve.  Fig. 2

      Fig. 3 - sleeve (3), is being rotated the required 180 degrees
by the motor (6)/belt (8) system.  After the the 180 degree rotation,
the picker assembly will retrieve the cartridge (2) from the sleeve
and move away.

Implementation #2 - This solution performs the flip by using a
slider, and linkage mechanism which causes the cartridge holding
sleeve to rotate.  The picker assembly is used to provide the
required motion, and force to activate/move...
