Abstract

A library cartridge storage or stacker system can have each cell location detected by the use of a Hall sensor. The Hall sensor identifies the location of a magazine containing a plurality of the cartridges and the particular cartridge location according to a binary code. Magnets are placed at each magazine and each cartridge. As shown in Fig. 1, a library system includes a plurality of magazines 1 contained in a vertical column between walls 2 and 3. A plurality of magazines are located in each vertical column and a plurality of columns are located in the storage area of the library system. Each magazine 1 holds a plurality of cartridges in spaces 4. Each of the spaces 4 support one cartridge 5 such that the bottom of the cartridge is spaced away from the base 6 and supported by the side members 7.

Cartridge Library System Position Sensing

A library cartridge storage or stacker system can have each cell location detected by the use of a Hall sensor. The Hall sensor identifies the location of a magazine containing a plurality of the cartridges and the particular cartridge location according to a binary code. Magnets are placed at each magazine and each cartridge. As shown in Fig. 1, a library system includes a plurality of magazines 1 contained in a vertical column between walls 2 and 3. A plurality of magazines are located in each vertical column and a plurality of columns are located in the storage area of the library system. Each magazine 1 holds a plurality of cartridges in spaces 4. Each of the spaces 4 support one cartridge 5 such that the bottom of the cartridge is spaced away from the base 6 and supported by the side members 7. The distance between the bottom of the cartridge 5 and the base of the opening 4 provides a slot 8 for inserting a picker arm (not shown) that is used by the library system to remove and replace cartridges. Each of the openings 4 includes a clip 9 that operates to retain a cartridge within the magazine 1. Slots 10 are provided in the base of each magazine 1 that meet with the rails 11 at the top for stacking the magazines 1 within the vertical column. Fig. 2 shows the detail A of Fig. 1. Each cartridge position of the magazine 1 includes cell sensor elements 11. Each magazine position within the vertical column includes a modular sensor element 12. The cell and module sensor elements are used to detect the library cell locations. The sensing is two-dimensional, one in the X direction and another one in the Y direction. A combination...
