The invention has for its object to provide a bearing assembly referred to in the preamble of claim 1, in which the flexibility in terms of storage topology is further increased.
This object is achieved by the invention defined in claim 1.
The basic idea of the invention is not only to use the overhead conveyor as a means of operating shelves of the shelf arrangement, but also in at least one shelf-free area as a vertical conveyor. In this way, the floor-free storage yard receives additional functionality, so that the provision of the floor-free storage yard anyway existing technical resources are better utilized by the inventive design. The shelf assembly according to the invention thus has a high flexibility with regard to the storage topology. Another advantage of the invention is that the functionality is increased over known bearing assemblies.
The topology of the shelf assembly with shelves and shelf aisles formed between the shelves can be selected within wide limits according to the respective requirements.
In addition, the bearing assembly according to the invention may also comprise two or more overhead free stacker trucks.
An advantageous development of the invention provides that the bearing arrangement in the horizontal direction in a first region which forms a shelf portion and a second region which forms or comprises the shelf-free area, and that the guide means in the horizontal direction to the second area extends. By way of example, and in particular, the second area can be a picking zone or supply zone, with the overhead-free stacker conveyor serving, on the one hand, to serve the shelves of the shelf area and, on the other hand, conveying piece goods into the picking zone. For this purpose, the overhead-free rack conveyor takes a piece goods in the shelf area and moves along the guide device, which may be formed for example by guide rails, in the horizontal direction to the second area. In this position, the load-carrying means of the overhead-free rack conveyor is lowered into the picking zone, where the piece goods can be sold or handed over to an external funding, such as a forklift.
An advantageous development of the aforementioned embodiment provides that the second area near the bottom has the shelf-free area and away from the shelf-free area shelves.
A particularly advantageous further development provides that at least one transfer station is formed in the shelf-free area, at which a piece goods conveyed by the floor-free stacker can be transferred to an external conveyor or can be taken over by the external conveyor. In this embodiment, the overhead-free rack conveyor serves in its function as a vertical conveyor to hand over cargo to an external funding or to take over from the external funding. For example, the overhead-free rack conveyor can transfer a piece goods to be outsourced at the transfer station to the external conveyor, which then conveys the piece goods in a shipping zone. Likewise, it is possible, for example from a production area adjacent to the storage arrangement, to transfer an article to be stored in the rack arrangement from an external conveyor to the overhead conveyor, which then stores the article at a suitable storage location in the rack arrangement. The external conveying means may be any suitable conveying means, for example a conveyor belt or a stacker or any other conveying means.
In order to increase the flexibility with regard to the transfer or takeover of piece goods from the rack conveyor to an external conveyor or from an external conveyor, an advantageous development of the aforementioned embodiment provides for at least two vertically spaced transfer stations.
Another development of the invention provides that in the second region of the shelf-free area is separated by an intermediate ceiling of the shelves having area and that in the false ceiling an opening for a load-handling means of overhead conveyance crane is formed. In this embodiment, the shelf-free area may be formed above the intermediate ceiling, in particular near the bottom, below the false ceiling and the shelves. If, for example, a picking zone is formed in the shelf-free area, it is prevented by the false ceiling that during the transport by means of the overhead-free stacker falling down cargo falls into the picking zone. In addition, in this embodiment, the space utilization is improved in an existing building by a lying above the order picking area for the storage of cargo can be used. Through the opening in the false ceiling, the overhead-free stacker can then carry in its function as Senkrechförderer piece goods in the picking zone.
