Description
Specification Dynamic Compact Storage The invention relates to a dynamic compact storage provided with a storage frame consisting of a plurality of storage planes disposed in superposition which are interconnected by vertically disposed transport shafts for vertical conveyor devices, there being provided in the storage planes transport paths for horizontal conveyor devices, the storage planes being provided with storage channels laterally of the transport paths in which loading units consisting of load supports for receiving stored goods are 1 s moveably arranged.
Such a dynamic compact storage is known from European Patent EP
0,500,065 B1. It describes a storage for storage goods to be transported on pallets which is provided with a storage frame consisting of several storage planes disposed in superposition and interconnected by vertically disposed transport shafts for vertical conveyor devices. Horizontally disposed transport paths for horizontal transport devices are provided in the storage planes.
Laterally of the transport paths there are arranged storage channels in which load supports for receiving the stored goods are moveable. In this storage, the entire storage frame is subject to a measured raster conditioned in accordance with the dimensions of the largest possible load unit. This results in the disadvantage that storage surface remains unused if one or more small parts on a large load support occupy a large storage space.
Furthermore, a storage system for receiving rolling pallets in storage planes disposed in superposition is known from German patent specification Attorney Docket 000381 DE 19 08 525 A1. Horizontally disposed transport paths are provided in each of the storage planes having associated therewith storage channels for pallets. in the transport paths, there are horizontal transport devices are moveably provided which transport individual pallets to the provided storage channels, deposit them at the beginning of a row and connect the pallet to further pallets in the storage channel to form a train of pallets. The storage planes are connected to each other by a vertical conveyor in a so-called removal tower. The described storage necessitated sub-dividing the storage into a permanent storage, a supplemental storage and a removal storage with partially different conveyor technology. Moreover, a service and removal ramp is required for removing goods from the pallets of each horizontal conveyor device which has to be moveable between all storage planes by a service person. In this arrangement the service and removal ramp has to be moved to the storage plane by a service person. As a result, quick deposits t5 and releases or pertormance of commission storage activities cannot be ensured. Moreover, increased safety requirements must be provided if the presence of persons is necessary in the actual storage area. This inevitably leads to increased costs for the conveyor devices and the construction of the storage. The performance of commission storage activities is complex in view of the fact that no suitable load supports are available for storage goods of different sizes.
Hence, the invention is based on the task to fashion a dynamic compact storage such that high turnover rates can be attained at comparatively low costs in terms of storage construction and conveyor devices. Moreover, it is to be possible to pertorm commission orders in particular quickly and safely. Furthermore, the novel structure is to make possible space-saving storage of storage goods of different sizes.
In accordance with the invention the task is accomplished by the characterizing elements of claim 1. Advantageous embodiments and Attorney Qocket 000381 improvements can be derived from the ensuing claims.
The advantages to be achieved by the invention are, in particular, the quick performance of storage and commission orders of storage goods of any desirable dimensions. To this end use is being made of a system of storage supports which complement each other in a modular manner which makes possible the storage of the entire storage and commission goods in a space-saving manner. Storage support with or without storage goods deposited thereon constitute a toad unit. The dynamic compact storage consists of a storage frame in which one or more storage planes arranged in superposed relationship and their associated vertically and horizontally disposed transport shafts and transport paths, as the case may be, form a functional unit. The storage frame is structured for the reception of load or functional units of different dimensions. One or more functional units of the same dimensions I S form a functional area. The arrangement of different functional areas for load carriers of different dimensions and the association of correspondingly dimensioned vertical and horizontal transport devices make it possible to arrange the different load units within the basic storage frame in any desired quantity and geometric arrangement, based upon their geometric dimensions (length x height x width) as well as related maximum weights and to transport them between receiving and delivery sites of the storage and to sort and prepare them as ready-made load units for trucks or other transportation devices. A modular structure of the different functional areas is made possible by arranging the load or functional units in a defined raster dimension. The raster dimension within the storage frame is defined by the by the geometric dimensions of the largest possible load unit consisting of storage support and storage goods. It is thus possible to arrange a multiple of smaller load units in a storage frame in a functional area which may be defined arbitrarily. The dimensions of the load or functional units may preferably be selected so as to make it possible to nest, at a minimum loss of space, as many combinations of load and functional units as possible in the Ilttomey doGWt 000381 larger functional areas and functional units. The individual functional areas or functional units form a complex geometric structure in which a smaller functional unit may be fractally inserted into the storage frame of a larger functional area. The functional units of the functional areas are logistically connected to each other by corresponding transport devices and, moreover, the functional units and functional areas advantageously logistically connected with at least one commissioning area. Furthermore, at feast one of these functional areas is connected to a receiving and delivery area.
A special advantage resides in the constant geometric nesting of the fractal storage elements (load support, storage goods, structure of the basic storage frame and of the storage frame in the functional areas). In this manner it is made possible at a later time to incorporate further functional units or enlargements of functional areas into the operational compact storage.
It is particularly advantageous that it is not necessary to enlarge the basic storage frame. Only the storage frames in the functional areas are restructured in accordance with the functional unit to be enlarged and the transport paths yr shafts are adjusted correspondingly. A later addition of transport devices for increasing the efficiency of one yr more functional areas is also possible without enlarging the basic storage frame. The modular construction of the entire compact storage permits such an enlargement of the storage yr individual functional areas as welt as an increase in efficiency by simple means.
A further advantage is provided by the storage administration system conceived for this storage. In case of a capacity enlargement the administrative system is capable of learning in respect of its administrative routine. Enlarging the capacity of the storage is automatically recorded upon start-up of the corresponding transport systems by a so-called teach-in llltomey OOCkCt 000381 4 process and is made available in the storage administration computer for all further administrative routine operations. This eliminates complex programming operations with involved start-up operations.
A further advantage is provided by equipping the individual functional units or functional areas with a sufficient number of vertical conveyor devices.
Short transportation paths to the operational areas in the commissioning zone result from associating each functional unit or functional area with several vertical conveyor devices connected by interfaces with a commissioning zone andlor the receivingldelivery areas. At these operational areas or work stations, storage goods may be removed from larger storage supports and stored on smaller storage supports. It is also possible at the same work station to reverse this operation by assembling smaller goods to a larger Ivad or to a functional unit.
A further advantage of the storage in accordance with the invention resides in the fact the individual functional units and their storage frame may be moved within the storage from one functional area to another functional area or to an intertace provided with a commissioning zone andlor goods receiving or delivery area. To accomplish this, at least one transport path is placed within the storage in respect of a functional area of functional units so that the functional unit may be transported in the manner of a moveable rack by a horizontal transport device to another functional area where there are, for instance, smaller load or functional units where it may then be taken up or delivered by the associated horizontal and vertical transport devices at that location. In this manner it is possible to maintain a smaller number of functional areas required for the smaller toad and functional units and of transport devices used there. This is of particular advantage if there are many articles which are only seldom required for the commisioning or assembly. In their moveable rack, these articles may be dynamically available at any Location in the storage and they may be fed to the functional Attorney l7ocket 000381 areas as required with smaller load or functional units.
The arrangement in accordance with the invention within the storage of the transport devices also results in additional advantages. Different horizontal and vertical transport devices may be constructed in such a manner that they may receive load or functional units of different dimensions.
To this end, the transport devices are provided with two yr more appropriately placed grippers, pallet handling devices or the like for the load supports which either operate simultaneously or individually. A particular characteristic of the structure of individual functional units and their storage frame is that two or more load or functional units may be moved simultaneously within the storage. In this connection, it is possible to move the load support either in a coupled state yr in an uncoupled state. The transport is carried out either by synchonously operating transport devices or by transport devices which can accept several load or functional units.
The particular advantage of this arrangement resides in the fact that two smaller load supports may be used for storing a larger article. 'This leads to a reduction in the number of the required types of toad supports and, at the same time, of the number of transport devices specially designed for a particular type of load support.
An embodiment of the invention has been depicted - in a purely schematic manner - in the drawings and will be described in greater detail hereafter.

Figures 1 to 4 depict the basic structural form in different presentations of a compact storage. For reasons of clarity, the basic storage frame which commonly is a steel structure, has not been shown.
Within the storage frame, the compact storage is provided with superposed storage planes 'I which are connected to each by vertical transport devices 3 arranged in vertically disposed transport shafts 2. In the storage planes 1, there are provided horizontally disposed transport paths 4 for horizontal transport devices 5. In the storage planes 1, laterally of the transport paths 4, there are provided storage channels 6 where the storage goods may be stored in load supports. The load supports with or without stored goods placed thereon form a load unit 7. The load supports have not been shown in detail. Preferably, pallets are used which are moveable as pallet trains or individually on rollers along rails or guide skids. Vertical transport devices 3 and horizontal transport devices 5 equipped with means for handling the pallets are provided as transport devices, so that the pallets Attorney Docket 000381 7 may be moved individually or in a connected state. Within the storage channels 6, the Ivad supports may be moved in different ways. In the embodiment shown, a pallet is used as a toad support which is moved in the storage channel 6 connected as a pallet train to several other pallets. To this S end the horizontal and vertical transport devices 3, 5 are equipped with an appropriate technology such that they connect or disconnect the incoming or outgoing pallet from the pallet train or deliver at, or receive from, the beginning of the channel an individual pallet. However, it is also possible to move the load supports in the storage channel 6 by satellite vehicles of the t 0 horizontal or vertical transport devices 3, 5 (not shown), Roller tracks are also possible and movement of the stored goods or of the load support by gravity is also conceivable. A further variant which has not been shown relates to transport devices installed in the storage channels 6 and provided with their own drives or with drives activated by the horizontal or vertical 15 transport devices 3, 5.
The compact storage is subdivided into functional areas 8 for load supports of different dimensions with associated vertical and horizontal transport devices 3, 5 dimensioned in accordance with the load supports.
20 The raster dimension within the functional areas 8 is determined by the geometric dimensions of the largest possible load unit 7 made up of a load support and goods stored thereon VlT~thin the storage frame, several superposed storage planes 1 and 25 their associated vertically and horizontally disposed transport shafts 2 yr transport paths 4 define a functional unit 9. The storage frame is structured to receive load or functional units 9 of different dimensions. One or more Ivad or functional units 9 of identical or different dimensions arranged in superposition andlor side by side and which may be services by the same 30 horizontal and vertical transport devices define a functional area 8. The storage frame is provided with at (east one functional area 8 incorporating Attorney Docket 000381 R
load and functional units 9 of larger dimensions and with at least one functional area 8 for load and functional units 9 of smaller dimensions.
The raster dimension within the storage frame is determined by the S geometric dimensions of the largest possible load unit 7 consisting of load support and the goods stored thereon. A multiple of smaller load and functional unites 9 may be nested into the storage frame of a functional area 8.
At )east one vertical and one horizontal transport device 3, 5 are associated with the functional areas 8 for load and functional units 9 of smaller and larger dimensions. At least one transport path 10 leading a an intertace 11 is associated with the functional areas 8. Load and functional units 9 of smaller and larger dimensions may be assembled at the interfaces.
The interface 11 shown schematically in Fig. 1 is structured as a commissioning area or as a goods receiving I goods delivery area.
In the embodiment shown, the functional areas 8 for the larger load supports are structured with separate transport devices designed tv accommodate the functional area 9. This functional area 8 is logistically connected to the remaining storage facility by the interface of the commissioning area 11 which has only been shown schematically in Figure 1.
One or more functional areas may be formed with transport devices universally adjustable to load supports of different dimensions.
r A further particular characteristic of the subject of the invention has been shown in Figure 3. A modularly graduated dimensioning of the load or functional units 9 makes it possible to form a functional unit of greater dimensions 15 by a plurality of smaller load and functional units 14 and to arrange it at any position in the functional area 16 of such a larger load or Attorney Docket 000381 functional unit 15. It is also possible arbitrarily to arrange only one individual Toad or functional unit 15 composed from load or functional units of smaller dimensions in a storage space in a functional area of larger dimensions 15.
Any number of load or functional units 14 may be geometrically structured such that they may be precisely nested into a larger functional unit and logistically connected with the receiving or delivery area and/or the commissioning area as well as with the remaining storage facility by appropriately dimensioned vertical and horizontal transport devices 3, 5.
Individual load or functional units 14 of smaller dimensions may be transported within the storage facility to functional areas 16 with load or functional units of larger dimensions and may be logistically connected with the remaining storage facility by the transport devices at those areas. The larger functional unit 7 5 is then structured as a moveable rack the planes of which have he same spacing as the transport'paths of the functional area with the toad or functional units 14 of smaller dimensions.
The performance of a cornmisioning order is described with reference to Figure 2. For this purpose it is assumed that it involves a two-step process. In the first step a load or functional unit of larger dimensions is transported from the functional area 8 to a work station in the commissioning area. To this end, a particular stored good A provided on the large load support is called up by the storage administration system. The horizontal transport device 5 moves in the transport path 4 to the beginning of the appropriate storage channel 6 and withdraws a toad unit structured, for instance, as a pallet, with the stored good arranged thereon. The pallet is transported to the vertical transport device 3 and by way of the transport shaft 2 and the transport path 10 it arrives at the interface 11, i.e. the commissioning area, which may be located on the same plane or any other plane.
Attorney Dock~t 000381 1 ~
The items located on this larger load or functional unit are separated at this location and placed on smaller load supports. These load units are thereafter moved by way of the corresponding transport path 10 for storage to a functional area for load or functional units of smaller dimensions. Mence, the commissioning area constitutes an interface 11 between two different functional areas. The commissioning becomes possible as soon as all the requisite articles have arrived in the required quantity at the functional area for toad or functional units of smaller dimensions. Small load supports are transported from the functional area for smaller load or functioning units to a I O work area or work station in the commissioning area in exactly the same steps as described in connection with large stored goods. The packaged items located on the smaller load or functional units are collected on a larger load support and are thereafter transported by the corresponding transport devices to the functional area for the larger load or functional units or to the storage output area directly.
The same work station may be utilized for separating as well as commissioning. The special advantages of such commissioning reside in its high flexibility and efficiency. Any number of customer orders with an arbitrary number of positions may be flawlessly assembled in any desired sequence. This may involve stored goods of any dimensions.
Special advantages result if the same horizontal storage devices 5 as the ones in the compact storage facility which are provided with means for handling the load supports are used for furnishing and clearing the work station of larger load or functional units 22. .;
The horizontal transport devices are used at the same time for furnishing the work 'station with empty load supports or load supports with empty wooden pallets from stacfcing devices for toad supports 19 andlor wooden pallets 20 positioned laterally of the horizontal transport device. The Attorney Docket 000381 I 1 horizontal transport devices 5 may be similarly utilized to transport emptied load supports andlor wooden pallets from the work station to the appropriate stacking devices 19, 20.
The horizontal transport devices 5 may at the same time be utilized for dynamically supplying and clearing commissioning sites located along the transport device_ To this end, empty wooden pallets are initially moved by the horizontal transport device 5 from a stacking device 20 to a receiving or delivery place 23. The commissioning person uses the wooden pallet tv IO collect individual packaged items from the larger load or functional units positioned along the horizontal transport device. The wooden pallets partially or completely assembled in this manner will be transported by the horizontal transport device 5 to the work station either directly by way of the receivingl delivery place or placed for intermediate storage in storage channels 6 positioned along the horizontal transport device prior to further commissioning. Commissioning by way of commissioning place 21 positioned along the horizontal transport device 5 is reasonably performed whenever many packaged items of one article have to be commissioned.
The combination of this commissioning with the commissioning at the work station constitutes a particularly efficient and cost-effective solution for an almost arbitrarily large variety of stored goods.
Figure 4 shows how individual functional units 9 may be arranged with respect to each other. Since the functional areas are of a uniform raster 2S dimension, different functional units 9 may also be arranged in superposed relationship by the corresponding horizontal and vertical transport devices 3, 5. This Leads to short transport paths 10 to and from the input and output storage area or interface 11 in the commissioning area, This, in turn, results in a very rapid separation and collection of goods.
Depending upon the volume of work to be performed at a work station, Attorney Docket 000381 I2 the operating demands regarding the delivery and removal of smaller load or functional units vary strongly. In this connection there may be operations or uses which necessitate a very high performance.
Figures 5 and 6 relate to the structure of a suitable work station. In them, the transport paths 10 are shown for smaller load and functional units towards and away from a work station at the interface 11.
One or more horizontal transport devices 5 are movable near the work station in higher or lower transport paths 4 of the storage planes 1. The horizontal transport devices 5 transport smaller load yr functional units 9 to one yr more vertical transport devices 3 arranged in a side by side disposition.
x5 In order to make possible the simultaneous transport of two load supports with a larger loaded article (see Figure 8), yr of load supports twice as large, there are always provided two vertical transport devices 3 in a side by side arrangement for supplying and clearing of the work station. To increase efficiency, further pairs of vertical transport devices are provided opposite this pair on the other side of the transport path 4 for horizontal transport devices 5.
The vertical transport devices furthest removed from the work station are provided with direct access to a conveyor lane 18 far transporting load or functional units toward and away from the work station. The remaining vertical transport devices deliver or receive load or functional units from the conveyor lane 18 by means of moveable transfer places 17. The transport efficiency for the load and functional units transported to or away from the work station may for all intents and purposes be arbitrarily increased or adjusted to prevailing demands, by an appropriate number of vertical aid horizontal transport devices. in this connection, it is of particular advantage Attorney Docket 000381 that the joining of material flows tv the transport lane 18 takes place exclusively in a vertical direction. In this manner shifting of loaded goods on the load supports is prevented.
Figure 7 depicts a horizontal transport device 5 far transporting load units 7 of different size.
Figure 8 depicts schematically that a large load unit 7 or voluminous loaded goods may be moved on finro load supports by synchronously operating vertical transport devices 3.
The dynamic compact storage operates with a storage administration system which is provided with a teaming ability in respect of its storage administration routine. The capacity of the storage is automatically recognized at an initial operation or a subsequent increase in capacity is automatically recognized at start-up of the additional transport devices. The requisite administrative routines are detected and made available on the basis of operating transport devices.

Such a dynamic compact storage is known from European Patent EP
0,500,065 B1. It describes a storage for storage goods to be transported on pallets which is provided with a storage frame consisting of several storage planes disposed in superposition and interconnected by vertically disposed transport shafts for vertical conveyor devices. Horizontally disposed transport paths for horizontal transport devices are provided in the storage planes.
Laterally of the transport paths there are arranged storage channels in which load supports for receiving the stored goods are moveable. In this storage, the entire storage frame is subject to a measured raster conditioned in accordance with the dimensions of the largest possible load unit. This results in the disadvantage that storage surface remains unused if one or more small parts on a large load support occupy a large storage space.
Furthermore, a storage system for receiving rolling pallets in storage planes disposed in superposition is known from German patent specification Attorney Docket 000381 DE 19 08 525 A1. Horizontally disposed transport paths are provided in each of the storage planes having associated therewith storage channels for pallets. in the transport paths, there are horizontal transport devices are moveably provided which transport individual pallets to the provided storage channels, deposit them at the beginning of a row and connect the pallet to further pallets in the storage channel to form a train of pallets. The storage planes are connected to each other by a vertical conveyor in a so-called removal tower. The described storage necessitated sub-dividing the storage into a permanent storage, a supplemental storage and a removal storage with partially different conveyor technology. Moreover, a service and removal ramp is required for removing goods from the pallets of each horizontal conveyor device which has to be moveable between all storage planes by a service person. In this arrangement the service and removal ramp has to be moved to the storage plane by a service person. As a result, quick deposits t5 and releases or pertormance of commission storage activities cannot be ensured. Moreover, increased safety requirements must be provided if the presence of persons is necessary in the actual storage area. This inevitably leads to increased costs for the conveyor devices and the construction of the storage. The performance of commission storage activities is complex in view of the fact that no suitable load supports are available for storage goods of different sizes.
Hence, the invention is based on the task to fashion a dynamic compact storage such that high turnover rates can be attained at comparatively low costs in terms of storage construction and conveyor devices. Moreover, it is to be possible to pertorm commission orders in particular quickly and safely. Furthermore, the novel structure is to make possible space-saving storage of storage goods of different sizes.
In accordance with the invention the task is accomplished by the characterizing elements of claim 1. Advantageous embodiments and Attorney Qocket 000381 improvements can be derived from the ensuing claims.
The advantages to be achieved by the invention are, in particular, the quick performance of storage and commission orders of storage goods of any desirable dimensions. To this end use is being made of a system of storage supports which complement each other in a modular manner which makes possible the storage of the entire storage and commission goods in a space-saving manner. Storage support with or without storage goods deposited thereon constitute a toad unit. The dynamic compact storage consists of a storage frame in which one or more storage planes arranged in superposed relationship and their associated vertically and horizontally disposed transport shafts and transport paths, as the case may be, form a functional unit. The storage frame is structured for the reception of load or functional units of different dimensions. One or more functional units of the same dimensions I S form a functional area. The arrangement of different functional areas for load carriers of different dimensions and the association of correspondingly dimensioned vertical and horizontal transport devices make it possible to arrange the different load units within the basic storage frame in any desired quantity and geometric arrangement, based upon their geometric dimensions (length x height x width) as well as related maximum weights and to transport them between receiving and delivery sites of the storage and to sort and prepare them as ready-made load units for trucks or other transportation devices. A modular structure of the different functional areas is made possible by arranging the load or functional units in a defined raster dimension. The raster dimension within the storage frame is defined by the by the geometric dimensions of the largest possible load unit consisting of storage support and storage goods. It is thus possible to arrange a multiple of smaller load units in a storage frame in a functional area which may be defined arbitrarily. The dimensions of the load or functional units may preferably be selected so as to make it possible to nest, at a minimum loss of space, as many combinations of load and functional units as possible in the Ilttomey doGWt 000381 larger functional areas and functional units. The individual functional areas or functional units form a complex geometric structure in which a smaller functional unit may be fractally inserted into the storage frame of a larger functional area. The functional units of the functional areas are logistically connected to each other by corresponding transport devices and, moreover, the functional units and functional areas advantageously logistically connected with at least one commissioning area. Furthermore, at feast one of these functional areas is connected to a receiving and delivery area.
A special advantage resides in the constant geometric nesting of the fractal storage elements (load support, storage goods, structure of the basic storage frame and of the storage frame in the functional areas). In this manner it is made possible at a later time to incorporate further functional units or enlargements of functional areas into the operational compact storage.
It is particularly advantageous that it is not necessary to enlarge the basic storage frame. Only the storage frames in the functional areas are restructured in accordance with the functional unit to be enlarged and the transport paths yr shafts are adjusted correspondingly. A later addition of transport devices for increasing the efficiency of one yr more functional areas is also possible without enlarging the basic storage frame. The modular construction of the entire compact storage permits such an enlargement of the storage yr individual functional areas as welt as an increase in efficiency by simple means.
A further advantage is provided by the storage administration system conceived for this storage. In case of a capacity enlargement the administrative system is capable of learning in respect of its administrative routine. Enlarging the capacity of the storage is automatically recorded upon start-up of the corresponding transport systems by a so-called teach-in llltomey OOCkCt 000381 4 process and is made available in the storage administration computer for all further administrative routine operations. This eliminates complex programming operations with involved start-up operations.
A further advantage is provided by equipping the individual functional units or functional areas with a sufficient number of vertical conveyor devices.
Short transportation paths to the operational areas in the commissioning zone result from associating each functional unit or functional area with several vertical conveyor devices connected by interfaces with a commissioning zone andlor the receivingldelivery areas. At these operational areas or work stations, storage goods may be removed from larger storage supports and stored on smaller storage supports. It is also possible at the same work station to reverse this operation by assembling smaller goods to a larger Ivad or to a functional unit.
A further advantage of the storage in accordance with the invention resides in the fact the individual functional units and their storage frame may be moved within the storage from one functional area to another functional area or to an intertace provided with a commissioning zone andlor goods receiving or delivery area. To accomplish this, at least one transport path is placed within the storage in respect of a functional area of functional units so that the functional unit may be transported in the manner of a moveable rack by a horizontal transport device to another functional area where there are, for instance, smaller load or functional units where it may then be taken up or delivered by the associated horizontal and vertical transport devices at that location. In this manner it is possible to maintain a smaller number of functional areas required for the smaller toad and functional units and of transport devices used there. This is of particular advantage if there are many articles which are only seldom required for the commisioning or assembly. In their moveable rack, these articles may be dynamically available at any Location in the storage and they may be fed to the functional Attorney l7ocket 000381 areas as required with smaller load or functional units.
The arrangement in accordance with the invention within the storage of the transport devices also results in additional advantages. Different horizontal and vertical transport devices may be constructed in such a manner that they may receive load or functional units of different dimensions.
To this end, the transport devices are provided with two yr more appropriately placed grippers, pallet handling devices or the like for the load supports which either operate simultaneously or individually. A particular characteristic of the structure of individual functional units and their storage frame is that two or more load or functional units may be moved simultaneously within the storage. In this connection, it is possible to move the load support either in a coupled state yr in an uncoupled state. The transport is carried out either by synchonously operating transport devices or by transport devices which can accept several load or functional units.
The particular advantage of this arrangement resides in the fact that two smaller load supports may be used for storing a larger article. 'This leads to a reduction in the number of the required types of toad supports and, at the same time, of the number of transport devices specially designed for a particular type of load support.
An embodiment of the invention has been depicted - in a purely schematic manner - in the drawings and will be described in greater detail hereafter.

Figure 7 is a horizontal transport device structured to receive toad units of different sizes;
Figure 8 depicts two simultaneously operating vertical transport devices for receiving two small toad supports with a large article thereon.
Figures 1 to 4 depict the basic structural form in different presentations of a compact storage. For reasons of clarity, the basic storage frame which commonly is a steel structure, has not been shown.
Within the storage frame, the compact storage is provided with superposed storage planes 'I which are connected to each by vertical transport devices 3 arranged in vertically disposed transport shafts 2. In the storage planes 1, there are provided horizontally disposed transport paths 4 for horizontal transport devices 5. In the storage planes 1, laterally of the transport paths 4, there are provided storage channels 6 where the storage goods may be stored in load supports. The load supports with or without stored goods placed thereon form a load unit 7. The load supports have not been shown in detail. Preferably, pallets are used which are moveable as pallet trains or individually on rollers along rails or guide skids. Vertical transport devices 3 and horizontal transport devices 5 equipped with means for handling the pallets are provided as transport devices, so that the pallets Attorney Docket 000381 7 may be moved individually or in a connected state. Within the storage channels 6, the Ivad supports may be moved in different ways. In the embodiment shown, a pallet is used as a toad support which is moved in the storage channel 6 connected as a pallet train to several other pallets. To this S end the horizontal and vertical transport devices 3, 5 are equipped with an appropriate technology such that they connect or disconnect the incoming or outgoing pallet from the pallet train or deliver at, or receive from, the beginning of the channel an individual pallet. However, it is also possible to move the load supports in the storage channel 6 by satellite vehicles of the t 0 horizontal or vertical transport devices 3, 5 (not shown), Roller tracks are also possible and movement of the stored goods or of the load support by gravity is also conceivable. A further variant which has not been shown relates to transport devices installed in the storage channels 6 and provided with their own drives or with drives activated by the horizontal or vertical 15 transport devices 3, 5.
The compact storage is subdivided into functional areas 8 for load supports of different dimensions with associated vertical and horizontal transport devices 3, 5 dimensioned in accordance with the load supports.
20 The raster dimension within the functional areas 8 is determined by the geometric dimensions of the largest possible load unit 7 made up of a load support and goods stored thereon VlT~thin the storage frame, several superposed storage planes 1 and 25 their associated vertically and horizontally disposed transport shafts 2 yr transport paths 4 define a functional unit 9. The storage frame is structured to receive load or functional units 9 of different dimensions. One or more Ivad or functional units 9 of identical or different dimensions arranged in superposition andlor side by side and which may be services by the same 30 horizontal and vertical transport devices define a functional area 8. The storage frame is provided with at (east one functional area 8 incorporating Attorney Docket 000381 R
load and functional units 9 of larger dimensions and with at least one functional area 8 for load and functional units 9 of smaller dimensions.
The raster dimension within the storage frame is determined by the S geometric dimensions of the largest possible load unit 7 consisting of load support and the goods stored thereon. A multiple of smaller load and functional unites 9 may be nested into the storage frame of a functional area 8.
At )east one vertical and one horizontal transport device 3, 5 are associated with the functional areas 8 for load and functional units 9 of smaller and larger dimensions. At least one transport path 10 leading a an intertace 11 is associated with the functional areas 8. Load and functional units 9 of smaller and larger dimensions may be assembled at the interfaces.
The interface 11 shown schematically in Fig. 1 is structured as a commissioning area or as a goods receiving I goods delivery area.
In the embodiment shown, the functional areas 8 for the larger load supports are structured with separate transport devices designed tv accommodate the functional area 9. This functional area 8 is logistically connected to the remaining storage facility by the interface of the commissioning area 11 which has only been shown schematically in Figure 1.
One or more functional areas may be formed with transport devices universally adjustable to load supports of different dimensions.
r A further particular characteristic of the subject of the invention has been shown in Figure 3. A modularly graduated dimensioning of the load or functional units 9 makes it possible to form a functional unit of greater dimensions 15 by a plurality of smaller load and functional units 14 and to arrange it at any position in the functional area 16 of such a larger load or Attorney Docket 000381 functional unit 15. It is also possible arbitrarily to arrange only one individual Toad or functional unit 15 composed from load or functional units of smaller dimensions in a storage space in a functional area of larger dimensions 15.
Any number of load or functional units 14 may be geometrically structured such that they may be precisely nested into a larger functional unit and logistically connected with the receiving or delivery area and/or the commissioning area as well as with the remaining storage facility by appropriately dimensioned vertical and horizontal transport devices 3, 5.
Individual load or functional units 14 of smaller dimensions may be transported within the storage facility to functional areas 16 with load or functional units of larger dimensions and may be logistically connected with the remaining storage facility by the transport devices at those areas. The larger functional unit 7 5 is then structured as a moveable rack the planes of which have he same spacing as the transport'paths of the functional area with the toad or functional units 14 of smaller dimensions.
The performance of a cornmisioning order is described with reference to Figure 2. For this purpose it is assumed that it involves a two-step process. In the first step a load or functional unit of larger dimensions is transported from the functional area 8 to a work station in the commissioning area. To this end, a particular stored good A provided on the large load support is called up by the storage administration system. The horizontal transport device 5 moves in the transport path 4 to the beginning of the appropriate storage channel 6 and withdraws a toad unit structured, for instance, as a pallet, with the stored good arranged thereon. The pallet is transported to the vertical transport device 3 and by way of the transport shaft 2 and the transport path 10 it arrives at the interface 11, i.e. the commissioning area, which may be located on the same plane or any other plane.
Attorney Dock~t 000381 1 ~
The items located on this larger load or functional unit are separated at this location and placed on smaller load supports. These load units are thereafter moved by way of the corresponding transport path 10 for storage to a functional area for load or functional units of smaller dimensions. Mence, the commissioning area constitutes an interface 11 between two different functional areas. The commissioning becomes possible as soon as all the requisite articles have arrived in the required quantity at the functional area for toad or functional units of smaller dimensions. Small load supports are transported from the functional area for smaller load or functioning units to a I O work area or work station in the commissioning area in exactly the same steps as described in connection with large stored goods. The packaged items located on the smaller load or functional units are collected on a larger load support and are thereafter transported by the corresponding transport devices to the functional area for the larger load or functional units or to the storage output area directly.
The same work station may be utilized for separating as well as commissioning. The special advantages of such commissioning reside in its high flexibility and efficiency. Any number of customer orders with an arbitrary number of positions may be flawlessly assembled in any desired sequence. This may involve stored goods of any dimensions.
Special advantages result if the same horizontal storage devices 5 as the ones in the compact storage facility which are provided with means for handling the load supports are used for furnishing and clearing the work station of larger load or functional units 22. .;
The horizontal transport devices are used at the same time for furnishing the work 'station with empty load supports or load supports with empty wooden pallets from stacfcing devices for toad supports 19 andlor wooden pallets 20 positioned laterally of the horizontal transport device. The Attorney Docket 000381 I 1 horizontal transport devices 5 may be similarly utilized to transport emptied load supports andlor wooden pallets from the work station to the appropriate stacking devices 19, 20.
The horizontal transport devices 5 may at the same time be utilized for dynamically supplying and clearing commissioning sites located along the transport device_ To this end, empty wooden pallets are initially moved by the horizontal transport device 5 from a stacking device 20 to a receiving or delivery place 23. The commissioning person uses the wooden pallet tv IO collect individual packaged items from the larger load or functional units positioned along the horizontal transport device. The wooden pallets partially or completely assembled in this manner will be transported by the horizontal transport device 5 to the work station either directly by way of the receivingl delivery place or placed for intermediate storage in storage channels 6 positioned along the horizontal transport device prior to further commissioning. Commissioning by way of commissioning place 21 positioned along the horizontal transport device 5 is reasonably performed whenever many packaged items of one article have to be commissioned.
The combination of this commissioning with the commissioning at the work station constitutes a particularly efficient and cost-effective solution for an almost arbitrarily large variety of stored goods.
Figure 4 shows how individual functional units 9 may be arranged with respect to each other. Since the functional areas are of a uniform raster 2S dimension, different functional units 9 may also be arranged in superposed relationship by the corresponding horizontal and vertical transport devices 3, 5. This Leads to short transport paths 10 to and from the input and output storage area or interface 11 in the commissioning area, This, in turn, results in a very rapid separation and collection of goods.
Depending upon the volume of work to be performed at a work station, Attorney Docket 000381 I2 the operating demands regarding the delivery and removal of smaller load or functional units vary strongly. In this connection there may be operations or uses which necessitate a very high performance.
Figures 5 and 6 relate to the structure of a suitable work station. In them, the transport paths 10 are shown for smaller load and functional units towards and away from a work station at the interface 11.
One or more horizontal transport devices 5 are movable near the work station in higher or lower transport paths 4 of the storage planes 1. The horizontal transport devices 5 transport smaller load yr functional units 9 to one yr more vertical transport devices 3 arranged in a side by side disposition.
x5 In order to make possible the simultaneous transport of two load supports with a larger loaded article (see Figure 8), yr of load supports twice as large, there are always provided two vertical transport devices 3 in a side by side arrangement for supplying and clearing of the work station. To increase efficiency, further pairs of vertical transport devices are provided opposite this pair on the other side of the transport path 4 for horizontal transport devices 5.
The vertical transport devices furthest removed from the work station are provided with direct access to a conveyor lane 18 far transporting load or functional units toward and away from the work station. The remaining vertical transport devices deliver or receive load or functional units from the conveyor lane 18 by means of moveable transfer places 17. The transport efficiency for the load and functional units transported to or away from the work station may for all intents and purposes be arbitrarily increased or adjusted to prevailing demands, by an appropriate number of vertical aid horizontal transport devices. in this connection, it is of particular advantage Attorney Docket 000381 that the joining of material flows tv the transport lane 18 takes place exclusively in a vertical direction. In this manner shifting of loaded goods on the load supports is prevented.
Figure 7 depicts a horizontal transport device 5 far transporting load units 7 of different size.
Figure 8 depicts schematically that a large load unit 7 or voluminous loaded goods may be moved on finro load supports by synchronously operating vertical transport devices 3.
The dynamic compact storage operates with a storage administration system which is provided with a teaming ability in respect of its storage administration routine. The capacity of the storage is automatically recognized at an initial operation or a subsequent increase in capacity is automatically recognized at start-up of the additional transport devices. The requisite administrative routines are detected and made available on the basis of operating transport devices.
