Description

"Shelf for high-bay or movable rack storage with rail systems"

The invention is directed to a rack for high-bay or mobile rack storage with rail systems in the individual rack levels, rack aisles and head ends as well as rack conveyors and carrier vehicles for stored goods or for pallets that can be moved on these rails with at least one movable order picking vehicle.

A device for forming a category is known from DE-OS 24 43 8 27, whereby a mobile order picking vehicle is provided on a rail system as a so-called trolley.

From EP-O 213 289 A1 it is known to temporarily assign supply and disposal vehicles to a number of O storage and retrieval machines, whereby it can be seen from the magazine DE-Z. Maschinenmarkt 1984, pp. 2401-2404 that industrial robots for loading shelf storage locations are generally known. Loading devices for shelf storage are also known from DE-21 07 824 &Pgr;2 or US-PS 3 583 584.

The known systems are usually special solutions, whereby it is known that the individual containers, pallets or similar in the warehouse can be loaded by a storage and retrieval machine.

or to remove items from storage or, for example, to remove items from pallets at individual storage locations until the pallet is empty and then to refill the pallets using another or the same storage conveyor. The removal device can also move to individual positions in a linear manner and thus at least limited picking work can be carried out.

The object of the invention is to create a solution with which order picking is made as fully automatic as possible and without restrictions, whereby waiting or idle times, in particular of the relatively complex robots or order picking vehicles, are avoided as far as possible.

In a rack of the type described at the outset, this object is achieved according to the invention in that the order-picking vehicle is designed as an automatic access robot, with a plurality of supply and disposal vehicles being assigned to it on both sides in the same rail level and on the upper and/or lower side in other rail levels.

The invention cleverly combines known partial solutions and mobilizes them in a special way. The invention enables a particularly flexible, fast and mobile division of work. This means that assembled commissions can be transported away

It can be used to feed an empty pallet for a
Commission, the removal of empty pallets from racking
The loading or feeding of full pallets into shelves can be controlled automatically without the need to interrupt the work of the order picking vehicle. The order picking vehicle can drive to individual positions regardless of the situation, and the connected supply and disposal vehicles can directly fulfil their respective intended function.
There are no _unnecessary downtimes for these vehicles.
The overall rail system allows for a high level of mobility in a simple manner.

The invention not only enables a possible two-sided assembly of goods on different
Vehicles are possible, so that access is possible for two different orders at the same shelf location, it is also achieved that the order picking vehicle itself does not hinder the flow of the vehicles, since these can be accessed either from one side or from the other.
side can be supplied or removed.

The invention also provides that each shelf level is equipped with at least one order picking vehicle.

In an embodiment, the invention also provides that at least part of the supply and disposal

The vehicles are designed as known automatic distribution vehicles equipped with goods-carrying arms that can be telescoped into the rows of shelves. This makes it possible to assign the additional function of pallet manipulation to the transport vehicles.

It is clear that the order picking vehicle is freed from tasks that lie outside the order picking process by the additional supply and disposal vehicles, which may be equipped with special functions; it can work continuously and is therefore optimally utilized. Minor delays can only occur when moving from one shelf level to another.

The invention is explained in more detail below with reference to the drawing, which shows in

Fig. 1 a front view of a row of shelves and in

Fig. 2 is a side view of a high-bay warehouse according to the invention.

In a shelf generally designated 1, which is equipped with individual rails 2 in the shelf levels, there is a picking vehicle 3 and, to the left and right of it in the case of Fig. 1, a supply and disposal vehicle

and 4a. Pallets 5 with goods 6 are only shown in outline. Carriers or rack conveyors 7 and 7a are indicated at the sides in Fig. 1.

In the example shown, the order picking vehicle 3 is shown as a four-wheel drive vehicle, to which a supply and disposal vehicle 4 is assigned on the left and right ^{. These} are connected to the order picking vehicle via a coupling 8.

which is only symbolically represented in the figure.

In Fig. 2, the order picking vehicle 3 is shown on one level in a row of shelves, with the pallet positions simultaneously forming the rails 2 for the order picking vehicle 3 and the supply and disposal vehicles.

The dashed line shows the possibility of this shift

system, e.g. via floor loops 2a, to form a closed rail system, i.e. the order picking vehicle 3 can drive into the individual shelf levels automatically. The alternative can be seen in Fig. 1, which consists in the order picking vehicle 3, e.g. by the edge-side shelf conveyor 7 or 7a, being able to be assigned to the individual shelf levels in a way that can be raised and lowered, just like the pallets. In Fig. 2, it is also indicated by dashed lines on the order picking vehicle 3 that a passenger cabin 9 can be provided there, in which a person can also

drive and carry out certain tasks.

Of course, the described embodiment of the invention can be modified in many ways without leaving the basic idea behind. In particular, the compressor can be of a type with only ^one of the four cylinders and can therefore be equipped with manipulation arms on the top and/or bottom in order to operate upper and/or lower supply and disposal vehicles and the like.
