The storage and retrieval unit is formed by a gantry crane (P) with two gripping receptacles ( 6 , 7 ) arranged one behind the other in the gantry crane direction of travel (F) and displaceable in the vertical direction (H), which are attached to a common, end, the two crane front sides arranged, motor-driven and in an end fixed point ( 8 ) chain ( 9 ) alternately for the choice of cassette or individual bar storage are vertically movable.

The gantry crane (P) has two Greifaufnah men ( 6 , 7 ) in its two outside the rack aisles ( 5 ), of which the cassette gripping receptacle ( 7 ) from one under the length front end of the cassette ( 2 ) to one - Outsourcing cross frame part ( 7 a) is formed. The single-rod gripping seat ( 6 ) is composed of a support spar ( 6 a) extending in the shelf longitudinal direction and since from both sides, in the longitudinal direction of the support spar spaced apart from each other, prisms ( 6 b) with the same and / or different Prism size together on the two side rails.

The two end frame parts ( 7 a) of the cassette gripping receptacles ( 7 ) and the support bar ( 6 a) with the support prisms 6 b) of the single rod gripping receptacle ( 6 ) are each on one end, by means of the two chains ( 9 ) Höhenver mobile carriage ( 10 , 11 ) stored.

The carriages ( 10 , 11 ) are guided with casters ( 12 , 13 ) in each second carriage ( 14 , 15 ) to a limited extent in the height direction (H) and these second carriages ( 12 , 13 ) run by means of rollers ( 16 , 17th ) on guides ( 18 ) of the gantry crane (P) and can be moved in the height direction (H) by stops (not shown) on the guides ( 18 ) to a limited extent. The carriages ( 14 , 15 ) strike the stops in the upper position and in the lowest position and then the carriages ( 10 , 11 ) of the gripping receptacles ( 6 , 7 ) forming the inner carriages can additionally be inserted into the second outer carriages ( 14 , 15 ) continue to move up and down until they hit the outer carriages ( 14 , 15 ) above and below.

Each inter-engagement seat (6, 7) has a total of four carriages (10, 14/11, 15) and that in both ends of the gantry crane (P) two carriages (10, 14/11, 15).

The two frame parts ( 7 a) of the cassette Greifaufnah men ( 7 ) are only attached to the inner carriage ( 10 ) and the single rod gripping receptacle ( 6 ) has a support bar ( 6 a) extending through the entire rack aisle ( 5 ), which is attached with its spar ends to the two inner carriages ( 11 ).

The two end-side chains ( 9 ) run from a chain station (store) (KS) via deflecting wheels ( 19 , 20 , 21 ) arranged in a fixed position in the portal crane (P) and one each can be rotated on the cassette carriage ( 10 ) and on the single-rod carriage ( 11 ) stored lifting wheel ( 22 , 23 ) to the end fixed point ( 8 ).

From the chain store (KS), each of the two chains ( 9 ) is turned slightly upwards via a guide plate ( 24 ) to the first deflection wheel ( 19 ), then downwards around the lifting wheel ( 22 ) of the cassette gripping seat ( 7 ) on the carriage side, and then upwards About two at the same height deflection wheels ( 20 , 21 ) for the single bar gripping seat ( 6 ) and then down around the lifting wheel ( 23 ) and up again to the fixed point ( 8 ), which as a tab with screw or the like. is designed to fix the chain end. The chain end on the storage side is attached to the guide plate ( 24 ).
