Abstract: 1475748 Selective retrieval systems ROBUR KONSULT AB 22 Aug 1974 [22 Aug 1973] 36979/74 Heading A4T A bank vault, Fig. 1, comprises stands 1 for deposit boxes 7, hand-in and hand-out positions 8, 8 for use by a customer, and an automated handling apparatus comprising a stacker 2 for use in transferring a required deposit box 7 from its storage position in the stands 1 to the hand-out position 8 and for retrieving same from the hand-in position to its original or a different storage position in the stands 1, the stacker forks 5 including grapple means 6 for engaging the required deposit box 7. When a customer requires a particular box 7 from the vault he prints the identification number of the box on a control panel 21 which is connected to a control unit 20 which includes a built-in programme incorporating a memory means storing data concerning the storage position of each deposit box 7, and the control unit 20 then directs the stacker 2 to the appropriate location in the stands 1 and the box 7 is then taken to the hand-out position 8. In Fig. 6 the hand-out position 8 is shown as being above the hand-in position 8 and the hand-out position has associated therewith an inner shutter 26 and an outer liftable shutter 27. After the customer has keyed in the box identification number the shutter 26 is lifted electro-mechanically and subsequently the stacker 2 arrives at the hand-out position and rests the required box 7 in that position without releasing it. A reader device 36, Fig. 6, checks the identification number of the box 7 and if it is correct the grapple means 6 releases the box 7 and the stacker 2 moves away, the inner shutter 26 is then closed and locked and the outer shutter 27 is subsequently released, and a signal lamp 11 indicates to the customer that the outer shutter 27 can be lifted to permit the box 7 to be withdrawn. Before the box 7 can be withdrawn the customer, by means of a personal key (38) Fig. 3 (not shown), withdraws bolts 13 of the deposit box 7 which are projecting into recesses at the side of the hand-out position. In the embodiment of Fig. 1, the hand-in/handout positions 8, 8 are in the wall of the vault, whereas in the embodiment of Fig. 5 the two said positions 8, 8 are in the wall of another room connected to the vault, and in this latter embodiment a vertical conveyer 19 is necessary to transfer a deposit box from the stacker 2 to the hand-out position 8, and vice versa from the hand-in position 8 to the stacker 2. When a deposit box is returned to the hand-in position 8, Fig. 6, bars 40 are moved outwards to prevent the box from being withdrawn, a second reader 39 reads the box's identification number, and after a shutter 43 has moved aside a built-in conveyer 43 transports the box, via a conveyer (44) to a magazine (45) having associated therewith a platform (47) from which the stacker 2 removes the boxes 7 individually for return to a storage position, Fig. 8 (not shown). The grapple means 6 comprises a claw (17) which engages a bracket (14) on the required deposit box (7), Fig. 4 (not shown), but this grapple means can be replaced by the grapple means shown in Fig. 11 (not shown), the latter comprising a turn-table (58) on which a catch arm (59), which engages with the required box (7), is mounted for movement along a path (60) under the action of a drive chain (64). The memory of the control unit 20 stores the addresses of empty storage compartments in the stands 1, and instead of the stacker 2 returning a box 7 to its original storage location the control unit 20 may direct the stacker 2 to return the box 7 to the nearest empty storage compartment, the memory then recording the new location of that box 7.
