Rack storage system comprising an improved load manipulation unit

A rack storage system, comprising

• a first storage rack and a second storage rack facing each other at a distance in a horizontal z direction,
• a rack aisle between the first storage rack and the second storage rack having a longitudinal axis extending horizontally in an x direction aligned orthogonally to the z direction,
• the first storage rack having
• storage locations for loading goods which are arranged next to one another on storage levels located on top of one another,
• front uprights, rear uprights, front longitudinal beams per storage level extending in the x direction and connected to the front uprights, rear longitudinal beams per storage level extending in the x direction and connected to the rear uprights, and a shelf having the storage locations per storage level which is arranged between the front longitudinal beam and the rear longitudinal beam,
• the second storage rack having
• storage locations for loading goods which are arranged next to one another on storage levels located on top of one another,
• front uprights, rear uprights, front longitudinal beams per storage level extending in the x direction and connected to the front uprights, rear longitudinal beams per storage level extending in the x direction and connected to the rear uprights, and a shelf having the storage locations per storage level which is arranged between the front longitudinal beam and the rear longitudinal beam,
• a loading good manipulation unit having a first buffer device offset laterally to the rack aisle in the z direction, and a first loading good lifting device for storing and/or retrieving loading goods arranged in a periphery of the rack aisle,
• the first buffer device having provisioning devices on at least some of the storage levels, wherein the provisioning devices are respectively configured for buffering a loading good or multiple loading goods and are arranged adjacent in the x direction on a side of the first loading good lifting device, or adjacent in the x direction on two sides of the first loading good lifting device, and
• the first loading good lifting device for storing and/or retrieving loading goods having
• a first vertical mast installed in a stationary manner, and affixed to the first storage rack,
• a first lifting drive with a drive station and a traction means drive,
• a first lifting frame supported on the first vertical mast and vertically movable using the first lifting drive, the first lifting frame being connected to the traction means drive of the first lifting drive, and
• a first transport device arranged on the first lifting frame, the first transport device being configured at least for transporting the loading goods between one of the provisioning devices and the first transport device in the x direction,
• guide tracks arranged respectively in pairs on the front longitudinal beams of the first storage rack and on the front longitudinal beams of the second storage rack in horizontal travel planes located on top of one another and extending in an x direction along the first storage rack, the second storage rack and the provisioning devices,
• at least one automated storage and retrieval unit having at least one load handling device for transporting the loading goods between the storage locations and the provisioning devices, the at least one automated storage and retrieval unit being displaceable in the x direction along the guide tracks on a travel plane in front of the storage locations and in front of the provisioning device, and
• a first conveying system for transporting loading goods to the first loading good lifting device and/or for transporting loading goods from the first loading good lifting device, the first conveying system being adjoined to the loading good manipulation unit,
• wherein the first loading good lifting device connects the first conveying system and the provisioning devices in terms of conveying.
