[Figure 9]1 shows a perspective view of a storage system according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0013] Preferred embodiments of the present invention will now be described with reference to the drawings.

[0014] FIG. 1 shows a top view of a shuttle system 10 according to the present invention with a retracted telescopic system 12 in FIG. 1(A) and an extended telescopic system 12 in FIG. 1(B).

[0015] As shown in FIG. 1(A), a shuttle vehicle 10 for transporting stored items in a shelving system includes a running gear 12 to which wheels 14-1...14-4 are attached, which are mounted on the shuttle vehicle, for moving the shuttle vehicle 10 along guide rails 16-1, 16-2 of the shelving system.

[0016] As shown in Figures 1(A) and 1(B), the telescopic system 18, which is movably guided by the running gear 12, can contract and extend in a self-supporting manner on either side of the running gear, in a plane relative to the running gear 12.

[0017] 1(A) and 1(B), the telescopic system 18 carries the storage containers 20-1 and 20-2. To store the storage containers 20-1 and 20-2, the telescopic system 18 is guided out from the side of the running gear 12 of the shuttle vehicle 10.

[0018] The storage containers 20-1, 20-2 are stored in the storage system by raising or lowering the telescopic system 18. For this purpose, the shuttle vehicle 10 is provided with a lifting system for raising and lowering the telescopic system 18 relative to the guide rails 16-1, 16-2 of the shelving system.

[0019] This means that on the one hand the shuttle vehicle 10 can perform upward and downward movements as a whole to achieve relative movement of the telescopic system 18 with respect to the support rails 16-1, 16-2 of the shelving system of the loading area.

[0020] Alternatively, the telescoping system 18 can also move relative to the running gear 12 if the guide rails 16-1, 16-2 of the shelving system run below the support rails of the shelving system.

[0021] As shown in Figure 1, the telescopic system 18 is configured in accordance with the present invention to be single-acting. This means that the telescopic arm of the telescopic system 18 is formed as one piece and can therefore move in a plane. This leads to a generally very simple construction of the shuttle vehicle 10, which is particularly important for increasing the efficiency of the shelving system.

[0022] Furthermore, within the scope of the present invention, the shuttle vehicle 10 is preferably configured as a shuttle vehicle for small loads.

[0023] The shuttle vehicle 10 may be provided with an assigned drive, for example a chain drive, to move the telescopic system 18. Alternatively, the telescopic system 18 may have its own drive, for example an electric motor, which allows for greater flexibility as there are no limitations regarding the insertion depth into the shelving system.

[0024] By combining the running gear 12 and the telescoping system 18, the present invention allows for arbitrary variable depth storage.

[0025] As shown in Figures 1(A) and 1(B), two storage containers 20-1, 20-2 may be used, for example, for dual-deep storage, where the shuttle vehicle can use the telescoping system 18 to load storage containers 20-1, 20-2 into the storage system or use the telescoping system 18 to remove storage containers 20-1, 20-2.

[0026] However, according to the present invention, when four-deep storage is performed, it is also possible to handle up to four containers each having a size of 400mm x 300mm. On the other hand, large containers with a total weight of up to 120kg are used for single-deep storage, and for double-deep storage, the containers can be sized as 600mm x 400mm. In general, containers can have a width of 300mm to 800mm and a length of up to 1600mm, and the dimensions shown are merely examples and do not limit the scope of protection of the present invention.

[0027] Overall, with the shuttle technology according to the invention, dynamic shelving and order picking can be used for products up to 1 tonne, depending on the industry, with the telescopic system 18 being used for feeding, lifting and retrieving or storing from below. This also offers advantages for applications in the automotive industry, for example, and the use of standardized VDA containers ("VDA" = "Verband der Automobilindustrie" [German Automobile Association]), as well as in the market segment for e-commerce solutions.

[0028] These advantages also relate in particular to efficiency and performance. In this respect, efficiency is defined in terms of storage, retrieval and redeployment movements, in particular double movements, according to the standard ("FEM" = "Federation Europeenne de la Manutention" [European Materials Handling Federation]). The performance improvements achievable within the scope of the present invention are an important advantage of the present invention.

[0029] FIG. 2 shows a perspective view of a shuttle vehicle according to the present invention.

[0030] As shown in Figure 2, the running gear 12 of the shuttle vehicle 10 is made up of a base plate 22, to the corners of which the wheels 14-1...14-4 of the shuttle vehicle 10 are attached. The wheels 14-1...14-4, or at least one pair of wheels 14-1...14-4, can be driven by a drive motor 24, which is coupled via a belt 26 to a rotating shaft connecting two opposing wheels 14-1...14-4 of the shuttle vehicle 10.

[0031] It is also possible within the scope of the present invention to drive one wheel shaft of the front or rear wheel pair, or both shafts, depending on the load on the shuttle vehicle 10 .

[0032] As shown in FIG. 2, the bottom of the shuttle vehicle 10 has at least two opposing contact surfaces 28 assigned to the front or rear wheel pairs, which direct the tilting force that occurs when the telescoping system 18 is extended onto the guide rails of the shelf system.

[0033] FIG. 3 shows a partial perspective view of a shuttle vehicle 10 according to the present invention.

[0034] Elements shown in FIG. 3, corresponding elements shown in FIG. 3 are designated by the same reference numerals and their description will not be repeated.

[0035] FIG. 3 shows in particular the construction of the lifting system according to the invention and further details of the telescopic system 18.

[0036] As shown in Figure 3, the lifting system for raising and lowering the telescoping system 18 can be configured relative to the running gear 12 of the shuttle vehicle 10. Alternatively, the lifting system for raising and lowering the entire shuttle vehicle 10 can be configured relative to the guide rails of the shelving system.

[0037] 3, the lifting system generally consists of holding blocks 30-1...30-4 attached to each corner of the running gear 12. Each holding block 30-1...30-4 has a passage channel through which a lifting column 32-1...32-4 is guided, respectively.

[0038] As shown in FIG. 3, height adjustment of the lifting columns 32-1...32-4 is performed by drive shafts 34-1, 34-2 driven by assigned motors 36-1, 36-2.

[0039] FIG. 3 also shows further details of the telescoping system 18.

[0040] 3, the telescopic system 18 includes at least one guide rail 38-1, 38-2 attached to the base plate 22 so that its direction of movement faces the side of the shuttle vehicle 10. Rollers 40-1, 40-2 are provided on the upper sides of the guide rails 38-1, 38-2.

[0041] 3, the telescoping system 18 further includes a loading area 42 movable along guide rails 38-1, 38-2, the loading area 42 having a cross-sectional shape with a transverse U-section disposed to engage rollers 40-1, 40-2 to guide the loading area 42 during movement.

[0042] As shown in Fig. 3, the movement of the loading area is performed by a drive for retracting and extending the loading area 42 relative to the shuttle vehicle 10 along at least one guide rail 38-1, 38-2. According to Fig. 3, one option for the drive is a chain conveyor. For this purpose, a conveyor chain 44 is guided along two gears 46-1, 46-2.

[0043] As shown in Figure 3, the shuttle vehicle 10 can be equipped with a double belt conveyor technology, for which a drive motor is also provided. Preferably, two conveyor belts of the double belt conveyor technology are provided along each longitudinal side of the loading area 42 of the at least one telescopic system 18. More preferably, the running surface of the double belt conveyor technology is also spaced apart from the surface of the loading area 42 of the telescopic system 18 by a predetermined distance greater than zero. This distance can be, for example, a value between 5 mm and 2 cm.

[0044] Furthermore, it should be noted that within the scope of the present invention, generally any number of belt conveyor devices can be used depending on the requirements, and these are operated by drives provided therefor, which can be, for example, electric motors (not shown in FIG. 3).

[0045] The shuttle vehicle 10 of the present invention further comprises a controller, which is preferably supplied with data relating to the movement and loading processes provided by an external control system of the shelving system via a wireless communication, e.g. WLAN, interface.

[0046] Energy storage devices can be provided for the energy supply of the electrical consumption of the shuttle vehicle 10, for example in combination with capacitor intermediate storage technology. Alternatively, energy can be supplied via conductor rails along the path along which the shuttle vehicle 10 travels.

[0047] FIG. 4 shows a bottom view of a shuttle vehicle 10 according to the present invention.

[0048] As shown in Figure 4, a further chain mechanism 48 is provided at the bottom of the shuttle vehicle 10 and engages with gears (hidden in Figure 4 by a cover 50) and is provided corresponding to the bottom of the gears 46-1, 46-2. Furthermore, a further gear 52 is provided which is rotatable via a drive device 54 shown in Figure 4 to operate the chain conveyors 44, 46-1, 46-2 shown in Figure 3.

[0049] FIG. 5 shows a further perspective view of the shuttle vehicle 10 according to the invention with the telescopic system 18 extended.

[0050] As shown in Figure 5, the items may be carried by load carriers 20-1, 20-2 having a predetermined length, height, and width. In this regard, the loading area 42 of the telescoping system 18 has a length that is twice the length and / or width of the load carriers 20-1, 20-2 for dual-depth storage.

[0051] As shown in Figure 5, the shuttle vehicle 10 is equipped with a single-acting telescoping system 18 that can extend to the right or left. In this regard, single-acting means extending in one plane, in order to achieve a minimum structural height.

[0052] As shown in FIG. 5, when the telescoping system 18 is extended, a minimum overlap between the telescoping system 18 and the shuttle vehicle 10 should be observed so that the tilting forces that occur can be captured.

[0053] According to the invention, when the construction height is small, by combining the telescopic system 18 with the lifting drive, any number of containers can be stored on the square shelves, the only limitation being the length of the telescopic system 18.

[0054] In accordance with the present invention, the shuttle vehicle 10 may be equipped with a variable number of telescoping systems 18 that may be operated independently of one another.

[0055] FIG. 6 shows a side view, a top view, and a front view of a shuttle vehicle according to the present invention positioned on a shelving system according to the present invention.

[0056] As shown in FIG. 6A, the storage boxes of the shelving system of the present invention have recesses 56 in the guide rails so that the telescoping system 18 of each shuttle vehicle 10-1, 10-2 can be retracted and extended relative to the storage boxes.

[0057] As shown in Figure 6(B), each storage box has a bearing surface 58, the distance of which is determined by the dimension between the storage containers 20-1, 20-2. Preferably, the contact surfaces are configured as angled rails to provide lateral support for the storage containers 20-1, 20-2 after they are deflated.

[0058] As shown in Figure 6(C), the shelving system's bearing surface 58 is positioned higher than the guide rails of the shelving system's shuttle aisle. Therefore, storage containers 20-1, 20-2 can be successfully placed by lifting them, storing them on the shelf, and then lowering the telescoping system 18. As mentioned above, this can also be done by raising the telescoping system 18 relative to the shuttle vehicle's 10 running gear. Alternatively, the entire shuttle vehicle 10 can be raised so that the loading area of ​​the telescoping system is positioned higher than the shelving system's bearing surface 58.

[0059] FIG. 7 shows a perspective view of a shuttle vehicle 10 according to the present invention arranged on a shelving system according to the present invention.

[0060] As shown in Figure 7, a shelving system according to the present invention includes at least one storage surface on which a plurality of storage boxes are arranged at right angles. The shelving system provides at least one shuttle aisle per location that passes directly between the opposing outer sides of the shelving system, with guide rails 60-1, 60-2 running along the storage boxes in this storage surface. Furthermore, a shuttle vehicle 10 according to the present invention can move along the shuttle aisle guide rails 60-1, 60-2 within the at least one shuttle aisle of the storage system to store and retrieve items.

[0061] 7, each storage box is provided with an L-shaped holding rail 58 running parallel to the other, the distance between which is greater than the width of the loading area 42 of the telescopic system 18. Therefore, when the height of the loading area 42 changes, the loading area between the holding rails 58 moves in the height direction, allowing the storage containers 20-1, 20-2 to be raised or lowered relative to the holding rails 58, and then the telescopic system 18 is retracted or extended depending on whether the storage containers 20-1, 20-2 are being stored or retrieved.

[0062] 7, the cross-sectional shape of the guide rails 60-1, 60-2 of each shuttle path has contact surfaces 62-1, 62-2 that form a shape corresponding to the opposing contact surface 28 (shown in FIG. 3) of the shuttle vehicle 10. In this manner, when the telescoping system 18 of the shuttle vehicle 10 is extended, engagement of the contact surfaces 62-1, 62-2 and the opposing contact surface 28 can prevent the shuttle vehicle 10 from tipping.

[0063] FIG. 8 shows a top view of a shelving system according to the present invention operating with at least one shuttle vehicle 10 according to the present invention.

[0064] As shown in FIG. 8, the shelving system 64 includes at least one storage surface on which a plurality of storage boxes are arranged at right angles.

[0065] As shown in FIG. 8, the shelving system 64 includes at least one shuttle aisle 66-1, 66-2 per storage surface that extends directly between opposite outer sides of the shelving system 64 that extend along the storage boxes of each storage surface.

[0066] Furthermore, the shelving system 64 according to the present invention includes at least one shuttle vehicle 10, as described in accordance with Figures 1 to 3. The shuttle vehicle 10 is capable of moving within at least one shuttle aisle 66-1, 66-2 of the storage system 64 to store and retrieve items stored using the telescopic technology according to the present invention.

[0067] As shown in FIG. 8, at least one lifting system 68-1, 68-2, 68-3, 68-4 is provided outside the shelving system 64 to enable the shuttle vehicle 10 and / or stored goods to be transported between different height storage levels relative to the individual storage surfaces of the shelving system 64.

[0068] 8, at least one conveyor or elevator system 68-1, 68-2, 68-3, 68-4 operatively functions as a front zone 70 of the shelving system 64. In this regard, inlet and outlet conveyor technology 72 is positioned on the opposite side of the elevator system.

[0069] FIG. 9 shows a perspective view of a shelving system according to the present invention.

[0070] As shown in Figure 9, conveyors or elevator systems 68-1, 68-2, 68-3, and 68-4 are provided at the ends of the shuttle aisles, respectively. The conveyors or elevator systems 68-1, 68-2, 68-3, and 68-4 can transport the shuttle vehicles 10 between the planes of the shelving system 64 or to the front zone 70. A combination of product conveyors and shuttle conveyors can also be used in accordance with the present invention. Conveyor belts can be loaded along the longitudinal sides of the shelving system 64, which advantageously allows for order picking space to be secured in combination with standardized products.

[0071] Furthermore, in accordance with the present invention, shuttle vehicles 10 containing stored items can be transported by conveyor or elevator systems 68-1, 68-2, 68-3, 68-4. Several shuttle vehicles 10 can be used per plane of shelving system 64. Combinations of goods and shuttle vehicle transport are also possible.

[0072] With respect to the shelving system 64 shown in FIG. 9, the following standardized procedure occurs.

[0073] A shuttle conveyor or lift system transports the shuttle vehicle 10 to the front zone 70, where it picks up the products to be stored. Conveyors or lift systems 68-2, 68-4 transport the shuttle vehicle 10 with the products to the logistically correct plane, where it drives onto the plane and subsequently deposits the products to be stored in the provided storage boxes. This procedure can be applied in reverse for retrieval.

[0074] By providing several lifting systems, it is possible to optimize routes and ensure redundant procedures as well.

[0075] As shown in Figure 9, a further advantage of the present invention is the combination of storage and order picking functions directly on the basis of the shelving system 64 and / or separate configurations in the shelving system 64. Thus, in the context of Industry 4.0 system solutions, the increasing demands regarding optimal solutions for storage, buffering, order picking and for higher-level communication via WLAN are met. The shuttle technology according to the present invention is characterized by low energy consumption and a very product-friendly solution.

[0076] In the area of ​​the front zone 70, the shuttle vehicle 10 is lifted to the correct height and then hands over the items stored on one side to the conveyor technology and picks up the items stored on the other side from the conveyor technology. In this respect, delivery and collection are carried out by telescopic technology or, if necessary, by chain conveyors arranged on the shuttle vehicle 10. The connection of the conveyor technology can be made up of several layers or on one side. Connections at both the front side of the shelves or along the shelving system 64 are also possible, in the position of the space for transfer to the shuttle vehicle 10.

[0077] According to the invention, if very high efficiency is required, one or more lifting systems can be provided on one side of the shelving system 64 for transferring stored items. In this case, the shuttle vehicles 10 transfer only stored items on each side to defined transfer stations, preferably at the end of the shuttle aisle.

[0078] From there, the containers, products, etc. are brought into the front zone 70 by a lifting system configured as a stock conveyor, with supply and discharge conveyor technology.

[0079] It is also possible within the scope of the present invention to transfer the shuttle vehicle 10 horizontally from one shuttle path to another.

[0080] According to the present invention, one or several order picking conveyor shelves can be combined with the shelving system 64, which provides particularly advantageous control of the storage and material handling of the entire system. Furthermore, depending on efficiency requirements, the number of shuttle vehicles 10 used within the shelving system can be variably determined.

[0081] If order picking conveyor shelves are arranged along the shelving system 64 for order picking, these are filled by the shuttle vehicle 10 at the top, i.e., on the side of the travel path. At the bottom, products can be removed from containers or directly from the load carriers. Empty load carriers can be returned via a conveyor shelf route that descends relative to the shuttle aisle. At the bottom, the stored items are sequentially retrieved by the shuttle vehicle 10, in this case using telescopic underfeed technology. If the interface to the shuttle vehicle 10 is configured by driven conveyor technology, double belt conveyor technology can be used in the shuttle vehicle 10 for retrieval.

[0082] For order picking, the conveyor shelves are provided with a display system, for example "pick by light" or "pick by voice".

[0083] Overall, the present invention allows for the use of very low, single-acting underfeed telescoping that allows for multi-depth storage in combination with shelving system 40. As a result, the conveyor shelves can be actively manipulated by telescoping system 18 during loading and unloading. As a result, the present invention allows for multi-depth storage to be achieved with telescoping system 18 that can be raised and lowered via the shuttle vehicle 10 lift system.
