发明名称 Passive payload for a cartridge handling system.
摘要 <p>Disclosed is an optical disk handling system (24), called an autochanger, having two control systems (150Y, l50Z) to provide the six motions necessary to move optical disk cartridges from storage holding cells to an optical drive. The system uses shaft encoders (62, 72) on two motors (60, 70) of the two control systems, and current or voltage feedback from the motors, for all positioning, and for detecting the location of the mechanisms during, and at the end of, moves. The shaft encoders (62, 72) are used to position a mechanism close to the eventual move location, then motor current or voltage feedback is used to determine the opposition to the movement of the mechanism, which tells the control system whether the mechanism has reached its destination. A human operator can enter a cartridge into the system through a mailslot (41), which is rotatable to properly receive or eject cartridges. The control systems use a flip assembly (49) in the autochanger to turn the cartridge over, allowing either side of the disk to be arranged for reading or writing by the optical drive. The control systems use a lateral displacement assembly (51) to move a cartridge from a cell in one of the two columns of the autochanger to a cell in the other column, or to move a cartridge between the optical drive, which is located in one of the columns, to a cell in the other column. The control systems use a cartridge engaging assembly (45) to attach to an exposed end portion of a cartridge positioned in a cell or the optical drive. A longitudinal displacement assembly (47) is used by the control systems to move the cartridge, after attachment, out of the cell or optical drive. After positioning the cartridge vertically and laterally, the longitudinal displacement assembly (47) is then used to move the cartridge into a cell or the optical drive, where the engaging assembly (45) releases the cartridge. An important aspect of the invention is that the longitudinal displacement assembly (47), the flip assembly (49), the lateral displacement assembly (51), the engagement assembly (45), and the mailslot assembly (41) are operated by one of the two control systems. The other of the two control systems is used for vertical displacement of the cartridge.</p>
