Abstract

A data storage library has two independent picker systems. Each can reach to four storage receptacle columns by having one vertical motion and two rotational motions. They can be independently operated and have the ability to pass each other in the vertical direction. The preferred embodiment of the design of this invention, as illustrated in Figs. 1 and 2, comprises: o Storage receptacle columns 1, extended in the Z direction, for storing the media cartridges 2, o Picker systems 3 which are transported along the Z direction by the carriages 4, the said carriages are guided by the rails 5 and moved by the motors 6 via cable system 7, each picker comprises a picker shell 8 and a gripping mechanism 9 to pick and insert cartridges 2.

Data Storage Library with Multiple Picker Systems for Continuous
Availability

      A data storage library has two independent picker systems.
Each can reach to four storage receptacle columns by having one
vertical motion and two rotational motions.  They can be
independently operated and have the ability to pass each other in the
vertical direction.  The preferred embodiment of the design of this
invention, as illustrated in Figs. 1 and 2, comprises:
  o  Storage receptacle columns 1, extended in the Z direction, for
      storing the media cartridges 2,
  o  Picker systems 3 which are transported along the Z direction by
      the carriages 4, the said carriages are guided by the rails 5
and
      moved by the motors 6 via cable system 7, each picker comprises
a
      picker shell 8 and a gripping mechanism 9 to pick and insert
      cartridges 2.  To reach all storage receptacle columns, the
      picker systems 3 are pivoted against the II' and OO' axis by
the
      actuators 10 and 11,
  o  Drives 12 which are mounted in the receptacle columns.

      With such an arrangement, the picker systems can be operated
independently, either in separated picker paths or in a same picker
path as long as one of them can change its picker path for passing
the other.

      The Fig. 3 illustrates an alternative arrangement wherein belt
loop pass through picker systems are used.  This approach eliminates
the requirement for p...
