A storage system of this type is known, for example, from DE 92 13 478 U1. This publication shows and describes a storage lift in which a computer-controlled loading and unloading device is guided in a shaft arranged between two rack columns. The stored goods are stored on storage goods carriers in the individual racks. The loading and unloading device transports the stored goods from their storage locations in the individual racks to a loading and unloading opening and back. The stored goods are stored or unloaded through the loading and unloading opening.

When operating such a storage system, it has proven to be disadvantageous that the stored goods in the area of the loading and unloading opening can be removed by anyone and, under certain circumstances, stolen.

In view of the disadvantages described, the present invention is therefore based on the object of creating a storage system with a storage area and an access area spatially separated from the storage area, as well as a system for managing it, in which access is restricted to at least part of the stored goods.

According to the invention, this object is achieved by an access control system assigned to the access area with a lock which is designed as a substantially horizontal platform and, depending on an access authorization code of a user, can be converted at least in sections from a locked state in which access to the stored goods is blocked to an unlocked state in which access to the stored goods is unlocked.

In this solution, the inventive access control system of the storage system only allows access to that part of the stored goods to which a user

can prove his access authorization using the access authorization code assigned to him.

According to the invention, the barrier fulfills a dual function as a horizontal platform and thus a working surface of the storage system and as part of the access control system of the storage system. In the solution according to the invention, the stored goods are not conveyed to an access area above the platform, as is the case with conventional storage systems with separate access and storage areas. Instead, the access area is arranged below the platform. In the storage system known from the prior art, a storage area is usually located in the place of the access area.

In order to determine a user's access authorization to a stored item, each stored item is assigned an authorization code, which is then compared by the access control system with the user's access authorization code. Only if the comparison shows that the user can access the stored item will the access control system grant access to the stored item with the corresponding authorization code.

Consequently, the solution according to the invention makes it possible to limit the misuse of the stored goods by allowing free access for everyone.

In some storage systems or storage lifts with separate storage areas and access areas, the stored goods are stored on storage goods carriers, such as containers or trays, and transported together with the storage goods carrier to the access area. The storage goods carriers can have compartments in which different storage goods are stored separately from one another. If such a storage goods carrier is transported to the access area, according to an advantageous embodiment, the storage system can be able to release access only to that part of the compartments or the stored goods to which the user is authorized according to the access authorization code. These individual sub-areas

Depending on the arrangement of the stored goods or compartments on the storage goods carrier, they can be arranged together or separately.

A particularly simple structural solution for the access control system is obtained when the barrier is arranged between the stored goods and the user.

The barrier can in particular also be designed as a bulkhead, cover or door or a combination of bulkheads, covers or doors, which is closed in the locked state and open in the released state.

In order to store goods of different sizes, the storage system can be provided with a size detection device for detecting the dimensions of the goods according to an advantageous embodiment. For example, such a size detection device can detect and save the height of the goods during storage. Depending on the dimensions, the goods are transferred to the access area at a corresponding distance from the barrier. In this embodiment, the position of the access area is therefore dependent on the size of the goods to which access is to be granted. In this embodiment, collisions between the goods and the barrier are avoided and security against misuse is increased, since only small gaps remain between the goods and the barrier.

If the storage system uses storage goods carriers in which several storage goods are always stored in compartments, possibly with different access authorizations, it is advantageous if, according to a further embodiment, the lock has a plurality of partial locks, by means of which a partial section of the access area can be transferred from the locked state to the released state depending on the access authorization code. A compartment of a storage goods carrier located in an access position in the access area is preferably assigned to a partial lock.

·

&igr; ·

The size of the partial barriers is advantageously dimensioned so that a partial barrier or a combination of adjacent partial barriers blocks exactly one compartment of a storage item carrier. By adapting the dimensions of the partial areas of the barrier to the dimensions of the compartments of the storage item carriers or the dimensions of the stored items, access is granted to precisely those stored items for which access authorization exists, without there being any possibility of access to compartments for which access authorization does not exist.

The partial barriers can advantageously be designed as flaps that are pivotably or slidably attached to the barrier.

In order to generally make unauthorized access to the storage system more difficult, all openings in the storage system through which access to the interior of the storage system is possible should be closed. It is therefore important to ensure that there is no way of getting into the interior of the storage system when the lock is released. Access should only be possible to the released stored goods. This can be achieved, for example, by locks that are flush with the storage goods carrier in the first access position and that form no or only small gaps.

In addition to the first access area just described, the storage system can, in a further advantageous embodiment, have a further, second, access area for the stored goods. This second access area differs functionally from the first access area in that it allows access to the stored goods in a second access position essentially without the influence of the access control system. In spatial terms, the second access area can differ from the first access area in that its position is different: In the second access area, the stored goods are arranged between the barrier and the user, so that the user has essentially free access to the stored goods. The use of the second access area enables the storage and retrieval of bulky stored goods that would not fit through the barrier or the partial barriers due to their dimensions.

In the design with a second access area, according to an advantageous development, an inner barrier is provided which is assigned to the second access area and is arranged between the second access area and the storage area. This barrier is opened to transport the stored goods from the storage area to the second access area and is closed as soon as the stored goods are in the second access position. This barrier blocks an entry opening through which the stored goods are introduced from the conveyor into the second access area.

The second lock can be formed by the lock for the first access area, so that the lock fulfills a dual function with regard to the two access areas. Alternatively, a second lock can be provided in addition to the lock of the first locking area, which can be actuated independently of the first lock.

In a further embodiment, an outer lock can be provided which is associated with the second access area and is arranged between the second access area and the user. The outer lock can block access to the interior of the storage system when the inner lock is open.

In a further advantageous embodiment, the second access area can be operated as a type of lock, so that when transporting stored goods between the second access area and the storage area, there is never any access to the interior of the storage system. The inner lock closes the entry opening on the storage area side, while the outer lock is open.

If, for example, a storage carrier is transported by the conveyor from the storage area to the access area, the outer lock is first closed and then the inner lock is opened so that the storage carrier can be transported through the entry opening to the access area. If the storage carrier is in the access area, the inner lock is

re closed and then the outer lock opened. In this position, access to the storage goods carrier is possible, but access to the interior of the storage area is blocked by the inner lock.

When storing goods, this process can be carried out in the reverse order if the goods to be stored have been placed in the access area. In a further advantageous embodiment, the access control system can also block access to the goods before the conveyor accesses the goods in the storage area or the goods in the access area. For example, if it is determined that a user does not have authorization to remove all of the goods on a goods carrier, in this embodiment the storage system will only signal the user that they do not have access authorization, but will not remove the goods from the access area or the storage area.

In an alternative, space-saving design of the storage system, in which the first and second access areas coincide spatially and only differ functionally in terms of the release of the access area, the lock of the first access area can simultaneously serve as the outer lock of the second access area. In this design, the lock of the first access area can be transferred as a whole to the release state in order to release the stored goods.

In the following, the structure and function of the invention are explained in more detail using exemplary embodiments.

Show it:

Figure 1 is a perspective view of a first embodiment of a

storage system according to the invention;

Figure 2 shows the storage system of Figure 1 with a storage goods carrier during the removal of stored goods;

Figure 3 shows the storage system of Figure 1 with a goods carrier during storage of goods;

Figure 4 shows another embodiment of a storage system with a

second access area and a lock system;

Figure 5 shows the storage system of Figure 4 when removing stored goods from the

second access position;

Figure 6 shows a third embodiment of the storage system.

First, the structure and function of a storage system 1 according to the invention are described with reference to Figure 1. In Figure 1, the side walls facing the viewer are omitted in order to provide an insight into the interior of the storage system 1.

The storage system 1 has two shaft-shaped storage areas 2, 3 in the form of shelf columns in which stored goods 4 are stored. The number of storage areas in the storage system is arbitrary. In Figure 1, the storage areas 2, 3 are constructed in the form of a shelf column with stationary storage locations 5 lying vertically one above the other. In the respective storage locations 5 of the storage areas 2, 3, the stored goods 4 are held by stored goods carriers 6, 7, which are accommodated in corresponding storage frames 8. The storage frame 8 forms rail-shaped holding means for the stored goods carriers 6, 7 at the respective storage locations 5.

The storage goods carriers 6, 7 can be designed in different ways. For example, the storage goods carriers 6 can be provided with compartments 9 in which different storage goods are stored in a sorted manner. The size and arrangement of the compartments 9 can vary depending on the stored goods. Some of the storage goods carriers 6, 7 can also be designed as trays 7, the shape of which essentially corresponds to a platform or a shelf. Storage goods 4 can be placed directly on the trays 7 or in storage goods carriers 6.

Between the storage areas 2, 3, a conveyor shaft 10 is arranged in which a conveyor 11 moves. In the embodiment of Figure 1, the

The storage frames 8 facing the conveyor shaft simultaneously serve as guides for the conveyor means 11. As a result, the conveyor means 11 is guided along the storage locations 5 - in Fig. 1 this is essentially in a vertical direction upwards and downwards.

The conveyor 11 is equipped with a gripping system (not visible in Fig. 1), such as is known from the prior art. The conveyor interacts with a storage goods carrier 6, 7 and moves the storage goods carrier from the respective storage location 5 into the conveyor shaft 10 and vice versa. The gripping means can be designed, for example, as a rotating finger on the conveyor, which engages in a corresponding finger holder on the storage goods side. Hydraulically operated telescopic arms can also serve as gripping means. The conveyor 11 together with the gripping system is automatically controlled by a control device (not shown).

In Figure 1, the storage system 1 is shown in a state in which a storage goods carrier 12 is being pulled by the conveyor 11 from the assigned storage location 13 into the conveyor shaft 10. As can be seen in Figure 1, the compartments 14 of the storage goods carrier 12 are larger and deeper than those of the storage goods carrier 6, so that larger storage goods can be stored in the compartments 14. In order to be able to manage storage goods 4 and storage goods carriers 6, 7, 12 of different sizes, the storage system 1 is equipped with a size detection device (not shown) by means of which at least the height and/or other dimensions of the storage goods 4 or the storage goods carriers 6, 7, 12 are detected.

The conveyor 11 transports stored goods 4 or stored goods carriers 6, 7 between the respective storage locations 5 in the storage areas 2, 3 and an access position 15 in an access area 16 which is spatially separated from the storage area 2, 3 and which is shown schematically with dotted lines in Figure 1. In the access area 16, access to the stored goods 4 or the stored goods carriers 6, 7 is possible from outside the storage system 1, i.e. storage and retrieval of stored goods and stored goods carriers. Access

to the stored goods 4 in the access area 16 takes place through the access opening 17 in an access direction 18.

An access control system 19, which is assigned to the access area 16, allows or blocks access to the stored goods in the access area 16 in a controlled manner. For this purpose, the access control system has a barrier 20, which is arranged above the access area 16, i.e. between a user and the access area 16. The barrier 20 also serves as a platform for the storage system and prevents unauthorized access to stored goods 4 in the access area 16. In contrast to conventional storage systems, in the embodiment of Fig. 1, the access area 16 with the access position 15 for the stored goods is located below the platform 20.

During storage, the height of the stored goods 4 or the stored goods carrier 6, 7 is determined and stored by the size detection device. During removal, this information is called up again and the stored goods 4 or the stored goods carrier 6, 7 is transferred by the conveyor 11 to an appropriate distance below the barrier 20 in the access position 15 of the access area 16.

The structure and function of the access control system 19 and the lock 20 are explained in more detail below:

In addition to the lock 20, the access control system 19 has a control module 21 with an input device 22 through which a user enters a predetermined access authorization code. In the case of manual access, a user is understood to be a person accessing the stored goods 4, and in the case of automatic access by automatic removal systems, the respective accessing system, for example a removal robot.

The input device 22 can be designed, for example, as a card reader for chip or magnetic cards, as a keyboard, scanner or as a contactless transponder system.

Using the access authorization code, the storage system 1 can determine whether the user is authorized to access the respective item using an automatically maintained inventory list in which the storage location 5 and a release code for the stored item are stored. To do this, the access control system 19 compares the release code assigned to the item 3 and the access authorization code assigned to the user. Depending on the result of this comparison, the access control system 19 will change the lock 20, at least in sections, from a locked state in which no access to the item is possible due to a lack of access authorization, to an unlocked state in which access to the item in the access area 16 is possible due to the user's existing access authorization.

The access authorization and release codes can be hierarchically staggered so that an access authorization code with a high level of access authorization allows access to the stored goods 4 or stored goods carriers 6, 5 that have a release code with a lower level of authorization. In large storage systems or in the case of complex storage tasks, several access hierarchies can also be implemented side by side.

In the case of storage goods carriers 6 which accommodate several storage goods, access can be restricted to only a part of the storage goods 4 in the storage goods carrier 6 by the access control system 19, depending on the access authorization code, when the storage goods carrier 6 is in the access position 15.

The partial release of stored goods from a storage goods carrier 6 in the access area 16 is described in more detail below.

In the access position 15 of the access area 16, the storage goods carrier 6 is at least partially covered, in Figure 2 completely, by the barrier 20 of the access control system 19, so that free storage and retrieval of storage goods 4 bypassing the access control system 19 is not possible.

·

In order to allow access only to individual sections of a storage goods carrier 6, the barrier 20 is divided into partial barriers 23. Each partial barrier 23 is designed as a separately controllable cover element which, depending on the user's access authorization code and the release code of the stored goods, enables or blocks access to the area below independently of other partial barriers. The partial barriers 23 of the barrier 20 form a field which together covers one side of the access area. The dimensions of the field correspond approximately to the dimensions of a storage goods carrier. In the embodiment shown, the partial barriers 23 are designed as flap-shaped covers which are arranged next to one another in several parallel rows and are separated from one another by webs in which the pivot bearings of the covers are accommodated.

Figure 2 shows how two partial locks 24a, 24b are opened. The partial lock 24a is shown in the fully opened state for access to a stored item 25 and the partial lock 24b is shown in the partially opened state. The partial locks are each assigned to the compartments 9 of a stored item carrier and are arranged in such a way that they cover the compartments 9 of a stored item carrier as completely as possible in the access position.

The dimensions of the compartments 9 and the area covered by a single partial lock 23 are in particular coordinated with one another in such a way that by opening a partial lock 23 or a combination of adjacent partial locks 23, access is possible to exactly one compartment 9 or to exactly one combination of adjacent compartments 9 with the same release code. This design prevents access to compartments for which the user does not have access authorization when opening a partial lock 23, but which would otherwise partially extend into the area released by the partial lock 23. The size of a partial lock 23 therefore corresponds to the size of a compartment 9 or an integer multiple of this size.

EJ \

·

In Figure 3, the storage system 1 or the access control system is shown in a state in which the adjacent partial locks 26, 27 are released due to an access authorization code that is different from that in Figure 2. The opened partial locks 26, 27 allow access to the stored goods 28. In contrast to Figure 2, in Figure 3 the partial lock 24 is locked due to a different access authorization signal, since in the process shown in Figure 3 the user has no authorization to access the stored goods 25 covered by the partial lock 23.

As can be seen in Figure 3, the storage item 28 that has just been removed is larger than the storage item 25 in Figure 2. Accordingly, the two adjacent covers 26 and 27 must be released in order to access the storage item 28. In order to prevent access to the adjacent compartments in the storage item carrier 6 in the access position 15, the size of the area released by the partial locks 26, 27 corresponds exactly to the size of the compartment in which the storage item 28 is accommodated.

The security of the access control system 19 against manipulation from outside can be further increased by providing as small a gap as possible between the compartments 9 and the lock 20, which prevents the removal of stored goods or the manipulation of the lock through the gap.

Figures 4 and 5 show a second embodiment of the storage system. In Figures 4 and 5, the same reference numerals are used for elements whose structure and function correspond to the elements of the embodiment of Figures 1 to 3.

The embodiment of Figures 4 and 5 is provided in addition to the lock 20 with an outer lock 29a and an inner lock 29b and a second access area 30. The second access area 30 is shown in dotted lines in Figures 4 and 5. The locks 29a, 29b work together in the manner of a lock system and are assigned to the second access area 30. The second

·

&igr;*·

Access area 30 is located above the barrier 20 and therefore allows access to the stored goods without the intervention of the access control system.

The front or outer barrier 29a is designed as a door that can be moved from top to bottom, transversely to the access direction 18, and which can be moved essentially in the plane of the access opening 17. The inner barrier 29b is arranged on the side of the access area 16 facing the storage areas 2, 3 and is also designed as a sliding door. The barrier 17 blocks an entry opening 31 through which stored goods 4 are transported above the access control system 19 by the conveyor 11 into a second access position 32 in the second access area 30.

The second access area 30 can be used for loading storage goods carriers with storage goods by a user with high access authorization or for storing and retrieving bulky storage goods that do not fit through the barrier 20 of the first access area 16.

The removal of a bulky individual item 33 using the lock system 29a, 29b is now described with reference to Figures 4 and 5.

The bulky individual item 33 on the tray 7 is brought by the conveyor 8 from the storage location to the second access area 16 above the barrier 20.

In order to prevent unauthorized persons from gaining access to the interior of the storage system through the entry opening 31 during the transfer of the individual item 33 to the second access area 30, the outer barrier 29a is first lowered and the access opening 17 is closed. Only then is the inner barrier 29b raised to release the entry opening 31, through which the individual item 33 is moved from the conveyor 11 to the second access position 32 within the access area 16.

In order to hold the individual item 33 securely in the second access position 32 above the barrier 20, corresponding holding devices, such as rails, projections or catches, can be arranged in the access area 16. The barrier 19 serves as a support on which the individual item 33 is placed with or without the tray 7.

As soon as the individual item 33 has reached the second access position, the inner lock 29b is moved downwards and the entry opening 31 is closed. The outer lock 29a is then opened to allow access to the individual item 33.

After removal of the individual item 33, the process is carried out in reverse order and the empty tray 7 is transferred back to the storage area 2, 3 assigned to it: The outer lock 29b closes the access opening 17, whereupon the inner lock 29a releases the entry opening 31; then the conveyor 11 pulls the tray 7 into the conveyor shaft 10 and deposits the empty tray 5 in the corresponding storage area 2, 3.

When loading the storage system 1 with a bulky individual item 33, the procedure is exactly the reverse: the empty tray 7 is moved into the access area 16 with the inner barrier 29b open, after which the inner barrier 29b is locked to close the entry opening 31 and the outer barrier 29a is raised to open the access opening 17. The stored item 33 is then placed on the empty tray 7, the outer barrier 29a is moved downwards and then the inner barrier 29b is moved upwards. With the outer barrier 29a closed, the stored item 33 is then transported by the conveyor 11 into the conveyor shaft 10 and deposited in a storage area 2, 3.

The process described above for bulky individual goods 33 can also be carried out for several items of storage that are stored in the storage goods carrier 6. This is briefly described below with reference to Figure 6.

Figure 6 shows a third embodiment of a storage system. In Figure 6, the same reference numerals are used for elements whose structure and function correspond to the elements of the embodiments described above.

In contrast to the previous embodiments, the access control system 19 of Figure 6 is designed as a retrofit kit that was installed in an existing, conventional storage system 1. For this purpose, fastening means (not shown) are provided on the barrier, which cannot be removed from the outside after installation, so that improper removal of the access control system 19 or the barrier 20 is prevented.

Furthermore, in contrast to the embodiment of Figures 4 and 5, the storage system 1 of Figure 6 does not have an additional inner barrier 29b, but only an outer barrier 29a. In this embodiment, in place of the inner barrier 29b there is a solid wall 34 that is opposite the access opening 17 of the access area 30. In the embodiment of Figure 6, the barrier 20 serves simultaneously as a barrier for the first access area 16 and as an inner barrier for the second access area. In this case, when stored goods are transferred to the second access area, the barrier 20 closes the entry opening for the second access area and forms the lock area together with the outer barrier 29b.

In order to transfer the storage goods carrier 6 from the storage area to the position shown in Figure 6 and back, the locks 20 and 29b interact like the locks 29a and 29b.
