Definitions
- the invention relates to an (automated) shelf storage system as described in the preamble of claim 1.
- Such rack storage systems include a rack aisle unit, which has a first storage rack, a second storage rack, a rack aisle extending in a longitudinal direction (X) between the first storage rack and the second storage rack, maintenance aisles and guideways running in the rack aisle and one or more automated transport vehicles as well as a Has cargo manipulation unit for storing and retrieving cargo.
- the first storage rack and the second storage rack have rack locations for loads that are arranged one above the other in rack levels.
- the maintenance aisles have accessible walkways arranged in maintenance levels one above the other.
- the respective transport vehicle can be moved in the rack aisle along the guideways and includes a transfer device for transferring load goods between a respective rack location and the transport vehicle.
- a transport vehicle is used for storing cargo in the storage racks and retrieving cargo from the storage racks.
- the load manipulation unit usually includes a first load transport device for storing loads and a second load transport device for removing loads.
- the first load transport device (for storing load goods) can be assigned a first buffer device, which can hold loads that are picked up by the transport vehicles and then transported away to the rack locations.
- the second load transport device (for retrieving load goods) can be assigned a second buffer device, which can receive loads that are released by the transport vehicles and then transported away by the load transport device.
- the rack storage system can include a transport vehicle lifting device for each rack aisle unit, which is set up to move a transport vehicle between different driving levels. - 2 -
- an ascent and/or descent device in a shelf storage system is known, for example, from US 2021/0137264 A1 and US 2015/0259979 A1.
- DE 102015 015 775 A1 discloses a rack storage system with rack aisle units as described above.
- the maintenance aisles there is an escape opening for each walkway and in the area of the escape opening there is a ladder that can be swiveled down (by gravity) into the respective maintenance aisle below.
- an escape opening can also lead through the storage racks and connect maintenance aisles to adjacent rack aisle units.
- ascent and/or descent units are present at opposite front end areas of the rack aisle units.
- a transport vehicle is absolutely necessary at each driving level.
- the arrangement of a transport vehicle lifting device, which is set up to transfer a transport vehicle between the different driving levels, is not possible. This results in a limited area of use for the known shelf storage system.
- the foldable ladder requires a relatively large amount of installation space in the vertical direction, so that the number of rack levels is also reduced in comparable rack storage systems.
- DE 10 2019 102 804 A1 also discloses a rack storage system with rack aisle units, as described above.
- an escape ladder and fall protection are provided at one end of the shelf aisle.
- An escape route leads from a maintenance corridor in the shelf aisle via the fall protection to the escape ladder.
- the fall protection is movable between a normal position and an escape position. In the normal position, the path between a maintenance aisle and a lifting path of the lifting device is blocked for the maintenance personnel. In the escape position, the path between a maintenance aisle and a lifting path of the lifting device is released for the maintenance personnel. If an emergency, such as a fire, occurs while the maintenance personnel are in the aisle unit, the maintenance personnel can escape from the aisle unit using a relatively short escape route.
- the loads referred to above can include containers, cartons, trays, pallets, hanging bags and the like. - 3 -
- One object of the invention is to create a rack storage system in which an operator can access a maintenance aisle within a rack aisle and/or leave an operator from a maintenance aisle within a rack aisle in a particularly simple manner.

- the one or more horizontal walkway sections and/or the one or more vertical walkway sections of the ascent and/or descent unit are arranged in a stationary manner.
- a vertical walkway section is provided, then this connects all horizontal walkway sections of the first shelf aisle unit that are arranged one above the other. If, according to another embodiment, several vertical walkway sections are provided, one vertical walkway section in each case connects two horizontal walkway sections of the first shelf aisle unit arranged one above the other. - 9 -
- the ascent and/or descent unit can be designed as a ladder or comprise one.
- the ascent and/or descent unit can also be designed as a stairway or comprise one. In this way, in particular, a comparatively comfortable exit from one or more maintenance aisles or access to one or more maintenance aisles can be implemented.

- a pedestrian passage and an access door assigned to it can be arranged almost arbitrarily along the longitudinal direction (X) on a storage rack, in particular on (just) one of the storage racks of the rack aisle unit.
- Such a pedestrian passage and/or such an access door can already be taken into account in the (structural) design of a storage rack. This can mean that the front shelf uprights and/or rear shelf uprights and/or front longitudinal beams and/or rear longitudinal beams and/or shelf levels with the shelf locations in the arrangement, in particular in terms of position, are matched to one another and connected to one another to form a storage shelf, that a pedestrian passage and/or an access door can be provided.

- a pedestrian passage and an access door associated therewith can be arranged between opposite ends of a storage rack in which the vertical passage runs or to which the vertical passage leads, for example in the first third, second third or third third. - 26 -
- said pedestrian passage and an access door associated therewith are arranged in the first third near the front end of said storage rack, the front longitudinal traverses end on a first passage side and relative to the pedestrian passage in front of the access door.
