Abstract

The storage system for large capacity containers (4) or pallets comprises shelves (3), along which a self-propelled carriage (2) moves the containers along rails. A lift (1) supplies containers to the unit and is mounted between two sets of shelves so that they one can be supplied while the carriage on the other is moving to or from its discharge position.

Description

The The invention relates to a storage system for storage and retrieval of containers, Pallets or other sizes Lagerhilfsmitteln / goods units with one or more independently and self-propelled self-propelled warehouses (LFZ) for operation in a rack warehouse (RL) and with a stacker crane (RBG) as it is already used several times today.

The Today's storage systems are used for multiple depth storage of uniform size storage units like pallets, containers or roles used. Here are right and left of a rack aisle on top of each other mounted storage channels arranged.

One Storage and retrieval unit (RBG), which is equipped with a lifting device and a load handling device, moves in the aisle of the aisle.

One Storage vehicle (LFZ) which is arranged on the load-receiving table is, can enter the warehouse channel to the nearest to the Regal goods to pick up or drop off.

The storage channels are designed with a track that makes it possible that enter the stock vehicle (LFZ) in the channel, drive under the goods and can lift out of the support by a Relativhub and thus can be moved out of the warehouse channel again.

disadvantage Today's storage systems have the disadvantage that between the Storage and retrieval unit (RBG), which is in the alley of the warehouse on the side shelves over moved and the warehouse vehicle (LFZ) which from the lift table of the stacker crane (RBG) is discharged into the storage channel, that is always a mechanical and / or electrical connection in the form of a wire rope and / or Cable / cable harness between storage and retrieval unit (RBG) and storage vehicle (LFZ) necessary is.

In order to is the storage and retrieval unit (RBG) in the period from the discontinuation of the storage vehicle (LFZ) to its return tied to the storage yard.

The Invention now relates to the use of several independent storage vehicles (LFZ) with a stacker crane (RBG) the handling capacity can be significantly increased. While that first storage vehicle has been discontinued in a rack channel can picked up the second shelf vehicle from a waiting area or other warehouse channel or be discontinued. Then the RBG is ready again for the first To pick up the warehouse vehicle with the goods in stock.

Conceivable are also the extension by using each of the double Number of storage vehicles compared to pickup positions on the stacker crane. The selection is dependent of the conditions such as routes, loads, etc.

Becomes the load handling device on the storage and retrieval unit (RBG) with a conveyor (Ex. Chain conveyors, Roller conveyors, Belt conveyor or Telescopic table), Thus, the goods at the at the deposit or Auslagerstelle the camp without passing the storage vehicle (LFZ) can be; is a further increase in throughput thereby possible, that the warehouse vehicle is independent of Presence of the stacker crane (RBG), already goods units at the beginning or end of the storage channel can rearrange while of the RBG receives a goods unit at the storage or retrieval station or gives up.

at with larger warehouses Multiple lanes and stacker cranes can handle the same throughput longer Regal channels provided and reduces the number of alleys or storage and retrieval equipment become.

at the same number of lanes and storage and retrieval machines (RBG) is the handling capacity considerably higher, which is a considerable time advantage when storing or retrieving or picking of orders brings with it.

to Implementation of this storage system must the warehouse vehicles (LFZ) are designed as independent systems.

In order to can contrary to today's systems, driving movements of the stacker cranes and driving movements the storage vehicles at the same time and no longer forced successively respectively. Depending on the dimensions of the storage system and shelf channel length can be up to 80% higher Handling services with only one additional shelf vehicle at otherwise the same bearing dimensions can be realized.

One inventive feature of independently operating storage vehicle (LFZ) now concerns the power supply of the shelf vehicle and its control for the travel and lifting movements in the bearing channel independently and without any mechanical Connection to the storage and retrieval unit to design and thus obtain a self-sufficient shelf vehicle.

This can on the one hand by busbars as a sliding conductor or non-contact as inductive Power transmission or done by a moving battery as a power source. The control technology connection to the storage and retrieval unit can be done via radio remote control, so that the storage and retrieval unit, while the shelf vehicle is in the rack channel, can change the location.

In addition, one allows moving small control and corresponding sensors it the warehouse vehicle (LFZ) in the warehouse channel independently to record the position of the goods units and exit; One or To be able to carry out stock transfers.

to Fall protection of the bearing vehicle is on the one hand a mechanical Lock only by the docking of the lifting device of the RBG is folded away and by an electrical switch on the storage vehicle, in the absence of the lifting device of the RBG, the traction drive switches off at the end of the storage channel.
