Abstract

The present disclosure relates to a storage and retrieval vehicle for a pallet storage system having at least one racking system and having at least one floor rail for moving the storage and retrieval vehicle, wherein the storage and retrieval vehicle comprises at least one linear guide, in particular a telescopic linear guide, outwardly coupled via at least one vertical guide to a base body of the storage and retrieval vehicle, and wherein the base body is rotatably arranged, in particular by 360°, about the vertical axis. The present disclosure further relates to a pallet storage system having a corresponding storage and retrieval vehicle and to a modular floor rail for a pallet storage system.

First claim

The invention claimed is:

1. A storage and retrieval vehicle for a pallet storage system having at least one racking system and having at least one floor rail for moving the storage and retrieval vehicle, wherein the storage and retrieval vehicle comprises:
a base body,
at least one vertical guide mounted to exterior, opposing sides of the base body, and
at least one linear guide coupled to an exterior of the base body, relative to a vertical axis, via the at least one vertical guide,
wherein the base body is rotatably arranged about the vertical axis.

2. The storage and retrieval vehicle in accordance with claim 1 , wherein the storage and retrieval vehicle comprises exactly one outwardly disposed linear guide or at least two outwardly disposed linear guides.

3. The storage and retrieval vehicle in accordance with claim 1 , wherein the storage and retrieval vehicle comprises a pallet receiver for lifting pallets of different widths; and/or the storage and retrieval vehicle comprises a change system comprising a coupling receiver configured for coupling at least one additional design of the pallet receiver.

4. The storage and retrieval vehicle in accordance with claim 1 , wherein transported products transported or held by the storage and retrieval vehicle by the linear guide at an outer region of the base body are held directly at the base body or at a minimal spacing of the base body from the storage and retrieval vehicle.

5. The storage and retrieval vehicle in accordance with claim 1 , wherein the storage and retrieval vehicle is movable on a sliding carriage along the floor rail and/or is movable in a horizontal plane and/or in a direction toward the floor rail.

6. The storage and retrieval vehicle in accordance with claim 1 , wherein an oil sump is pivotably and couplably arranged beneath at least one carriage at the storage and retrieval vehicle.

7. The storage and retrieval vehicle in accordance with claim 6 , wherein an oil tray is provided in a lower region of the storage and retrieval vehicle; and/or in that the oil tray is movable, deformable, and/or insertable flexibly and/or relative to the storage and retrieval vehicle in at least one direction.

8. The storage and retrieval vehicle in accordance with claim 1 , wherein the storage and retrieval vehicle is operable via at least one energy store, and/or with the energy store being replaceable, with the storage and retrieval vehicle having a replacement station for a manual and/or automatic replacement of the energy store.

9. A pallet storage system having:
at least one racking system,
at least one storage and retrieval vehicle, and
at least one floor rail for moving the storage and retrieval vehicle,
wherein the storage and retrieval vehicle comprises a base body of the storage and retrieval vehicle and at least one linear guide outwardly coupled, relative to a vertical axis to exterior, opposing sides of the base body via at least one vertical guide, and
wherein the base body is rotatably arranged about a vertical axis.

10. The pallet storage system in accordance with claim 9 , wherein the at least one floor rail is composed of modules that are connectable to one another; and/or in that the at least one racking system is composed of modules that are connectable to one another.

11. The pallet storage system in accordance with claim 9 , wherein a region reachable by the storage and retrieval vehicle comprises both longitudinal sides and transverse sides of the floor rail, with parts of the racking system and/or other components to be reached by the storage and retrieval vehicle being arranged at at least one transverse side of the floor rail.

12. The pallet storage system in accordance with claim 9 , wherein a barrier is providable between a movement region of the storage and retrieval vehicle and further components of the pallet storage system; and/or in that frontal access for operators is provided between the floor rail and at least one component of the pallet storage system.

13. The pallet storage system in accordance with claim 9 , wherein the racking system comprises at least one driven rotationally symmetrical rack that is a transfer station that is oriented toward the storage and retrieval vehicle.

14. The storage and retrieval vehicle in accordance with claim 1 , wherein the at least one linear guide is a telescopic linear guide, and wherein the base body is rotatably arranged by 360° about the vertical axis.

15. The storage and retrieval vehicle in accordance with claim 3 , wherein the pallet receiver is adjustable in width.

16. The storage and retrieval vehicle in accordance with claim 7 , wherein the oil tray is movable in a horizontal direction.

17. The pallet storage system in accordance with claim 10 , wherein the floor rail modules and/or the racking system modules are of a same design.

18. The pallet storage system in accordance with claim 12 , wherein the further components of the pallet storage system are machine tools or other automation solutions for a reliable separation of the movement region of the storage and retrieval vehicle from the further components of the pallet storage system.

19. A storage and retrieval vehicle for a pallet storage system having at least one racking system and having at least one floor rail for moving the storage and retrieval vehicle, wherein the storage and retrieval vehicle comprises at least one linear guide outwardly coupled via at least one vertical guide to a base body of the storage and retrieval vehicle, wherein the base body is rotatably arranged about a vertical axis, wherein the storage and retrieval vehicle comprises exactly one outwardly disposed linear guide or at least two outwardly disposed linear guides, and wherein two outwardly disposed linear guides are arranged angled by 90° with respect to one another and/or in that two carriages for receiving, removing, and/or holding transported products are arranged angled by 90° with respect to one another.

20. A storage and retrieval vehicle for a pallet storage system having at least one racking system and having at least one floor rail for moving the storage and retrieval vehicle, wherein the storage and retrieval vehicle comprises at least one linear guide outwardly coupled via at least one vertical guide to a base body of the storage and retrieval vehicle, wherein the base body is rotatably arranged about a vertical axis, wherein the storage and retrieval vehicle comprises a pallet receiver for lifting pallets of different widths and/or in that the storage and retrieval vehicle comprises a fast-change system for coupling at least one further design of the pallet receiver, and wherein an oil tray is provided in a lower region of the storage and retrieval vehicle and/or in that the oil tray is movable, deformable, and/or insertable flexibly and/or relative to the storage and retrieval vehicle in at least one direction, or the pallet receiver is adjustable in width.

21. The storage and retrieval vehicle in accordance with claim 1 , further comprising a coupling receiver shaped to receive a pallet receiver and a lock coupled to the coupling receiver.
