Description

[0001] The present invention relates to a racking system with a shuttle vehicle, and in particular to a racking system with a shuttle vehicle in which a telescopic undercarriage technology is used for storing and retrieving loads.

[0002] German patent application DE 10 2013 013 274 A1 describes a transport robot with a lifting unit for transported goods. It is a rail-bound transport robot with a loading device for picking up and unloading transported goods at storage locations in rack storage systems. The loading device consists of at least one loader arm, which is driven to move transversely to the direction of travel of the transport robot and in which at least one lifting device is arranged.

[0003] Furthermore, a single-location rack storage system is known from DE 91 03 498 U1. This system contains at least two racks in which rows of storage locations are arranged one above the other in horizontal planes, and the storage locations are accessible via an aisle between the racks.

[0004] Furthermore, US 2016 / 0060037A1 describes a storage system with multiple storage sections, each configured to store containers in storage cells and arranged in multiple rows across numerous horizontal planes relative to the Earth. Several groups of lift transport devices are configured for movement in a first horizontal direction along paired rails, arranged in predefined first horizontal planes at passages between adjacent storage sections.

[0005] A storage and order picking system is known from DE 10 2014 012 254 A1. This system is used for storing and picking goods and comprises a racking system with rows of racks spaced apart by longitudinal aisles and connected to each other by means of at least one transverse aisle. Furthermore, at least one shuttle, designed to travel in both the longitudinal and transverse aisles of the racking system, and at least two load handling vehicles, which can be picked up simultaneously on the shuttle, are provided.

[0006] Finally, DE 32 07 860 A1 discloses a conveying device for a warehouse facility. This device consists of an undercarriage equipped with at least two independently operable lifting platforms for picking up and setting down load units.

[0007] In existing storage systems and small parts warehouses, storage and retrieval systems form the basis for stocking and retrieving items from storage boxes within a storage system.

[0008] However, such storage and retrieval machines are regularly slow and limited in terms of storage depth.

[0009] Furthermore, such industrial trucks regularly require additional space for maneuvering, so their use leads to a reduction in the storage capacity available.

[0010] Accordingly, the technical problem of the present invention lies in increasing the flexibility and throughput of a storage system.

[0011] According to the present invention, this technical problem is solved by a shuttle vehicle according to claim 1.

[0012] Furthermore, the technical problem of the present invention is solved by a shelving system according to claim 11.

[0013] Further advantageous embodiments of the present invention are specified in the dependent claims.

[0014] Preferred embodiments of the present invention are described below with reference to the drawings; they show Fig. 1 a top view of the shuttle vehicle according to the invention with the telescopic system extended or retracted; Fig. 2 a perspective view of the shuttle vehicle according to the invention; Fig. 3 a partial perspective view of the shuttle vehicle according to the invention; Fig. 4 a bottom view of the shuttle vehicle according to the invention; Fig. 5 a perspective view of the shuttle vehicle according to the invention with the telescopic system extended; Fig. 6 a side view, a top view, and a front view of a shuttle vehicle according to the invention positioned in a racking system according to the invention; Fig. 7 a perspective view of a shuttle vehicle according to the invention positioned in a racking system according to the invention; Fig. 8 a top view of a bearing system according to the invention; and Fig. 9 a perspective view of the bearing system according to the invention.

[0015] Fig. Figure 1 shows a top view of a shuttle system 10 according to the invention with the telescopic system 12 retracted. Fig. 1(A), and with extended telescopic system 12, Fig. 1(B).

[0016] As in Fig. As shown in Figure 1(A), the shuttle vehicle 10 for transporting stored goods in the racking system includes a chassis 12 with wheels 14-1, ..., 14-4 mounted thereon, in order to move the shuttle vehicle 10 along guide rails 16-1, 16-2 of the racking system.

[0017] As in Fig. 1(A) and Fig. As shown in Figure 1(B), a telescopic system 18, movably guided by the chassis 12, can be extended and retracted. This occurs relative to the chassis 12 in one plane and in a self-supporting manner on both sides of the chassis.

[0018] As in Fig. 1(A) and Fig. Figure 1(B) shows the telescopic system 18 carrying storage containers 20-1, 20-2. To store the storage containers 20-1, 20-2, the telescopic system 18 is extended from the side of the chassis 12 of the shuttle vehicle 10.

[0019] The storage containers 20-1, 20-2 are placed into the storage system by raising or lowering the telescopic system 18. For this purpose, the shuttle vehicle 10 contains a lifting system for raising and lowering the telescopic system 18 relative to the guide rails 16-1, 16-2 of the racking system.

[0020] This means that, on the one hand, the shuttle vehicle 10 as a whole can perform an up and down movement in order to achieve a relative movement of the loading platform of the telescopic system 18 relative to the storage rails 16-1, 16-2 of the racking system.

[0021] Alternatively, the telescopic system 18 can also be moved relative to the chassis 12, provided that the guide rails 16-1, 16-2 of the racking system run below the storage rails of the racking system.

[0022] As in Fig. As shown in Figure 1, according to the present invention, the telescopic system 18 is of single-acting design. This means that the telescopic arm of the telescopic system 18 is single-section and can therefore be moved in one plane. This results in a generally very low profile for the shuttle vehicle 10, which is of particular importance for increasing efficiency in the racking system.

[0023] Furthermore, within the scope of the present invention, the shuttle vehicle 10 is preferably designed as a shuttle vehicle for low loads.

[0024] For the operation of the telescopic system 18, the shuttle vehicle 10 can be equipped with an associated drive, for example a chain drive. Alternatively, the telescopic system 18 can be equipped with its own drive, for example an electric motor, which increases flexibility because there are then no restrictions with regard to the insertion depth into the racking system.

[0025] By combining the chassis 12 and the telescopic system 18, it is possible according to the invention to carry out multi-deep storage in any variability.

[0026] As in the Fig. 1(A) and Fig. As shown in Figure 1(B), for example, two storage containers 20-1, 20-2 can be used in a double-deep storage system. Shuttle vehicles load the storage system or remove the storage containers 20-1, 20-2 using the telescopic system 18.

[0027] According to the present invention, for example, up to four containers measuring 400 mm x 300 mm can be handled, provided they are stored in a four-deep configuration. Alternatively, in single-deep storage, large containers with a total weight of up to 120 kg can be used, and in double-deep storage, the containers can have a size of 600 mm x 400 mm. Generally, containers can have a width of 300 mm to 800 mm and a length of up to 1600 mm; these dimensions are merely examples and do not in any way limit the scope of the present invention.

[0028] Overall, according to the shuttle technology of the invention, dynamic rack storage and order picking applications can handle products weighing up to 1 ton, depending on the industry, whereby a telescopic system 18 is used to move underneath, lift, and retrieve or store the products. This offers advantages, for example, in applications in the automotive industry or when using standardized VDA containers, as well as in the e-commerce market.

[0029] These advantages particularly relate to throughput and performance. Throughput is defined here according to the standard (FEM) by loading, unloading, and transfer cycles, especially double cycles. The performance improvement achievable within the scope of the present invention is a significant advantage.

[0030] Fig. Figure 2 shows a perspective view of the shuttle vehicle according to the invention.

[0031] As in Fig. As shown in Figure 2, the chassis 12 of the shuttle vehicle 10 is constructed from a base plate 22, at the corners of which the wheels 14-1, ..., 14-4 of the shuttle vehicle 10 are mounted. The wheels 14-1, ..., 14-4, or at least a pair of the wheels 14-1, ..., 14-4, can be driven by means of a drive motor 24, which is coupled via a belt 26 to a rotatable shaft that connects two opposing wheels 14-1, ..., 14-4 of the shuttle vehicle 10.

[0032] Within the scope of the invention it is also possible to drive either one wheel shaft of the front or rear wheel pairs or, depending on the load of the shuttle vehicle 10, both shafts.

[0033] As in Fig. As shown in Figure 2, the shuttle vehicle 10 has at least two counter-contact surfaces 28 on its underside, assigned to a front or rear wheel pair, by means of which tilting forces occurring when the telescopic system 18 is extended can be introduced into the guide rails of the racking system.

[0034] Fig. Figure 3 shows a partial perspective view of the shuttle vehicle 10 according to the invention.

[0035] The one in Fig. 3 elements shown, which correspond to those shown in Fig. The items shown in Figure 3 are identified by identical reference symbols, and their descriptions are not repeated.

[0036] The Fig. Figure 3 shows in particular the design of a lifting system according to the invention and further details of the telescopic system 18.

[0037] As in Fig. As shown in Figure 3, the lifting system can be configured to raise and lower the telescopic system 18 relative to the chassis 12 of the shuttle vehicle 10. Alternatively, the lifting system can be configured to raise and lower the entire shuttle vehicle 10 relative to the guide rails of the racking system.

[0038] As in Fig. As shown in Figure 3, the lifting system generally consists of 12 holding blocks 30-1, ..., 30-4 mounted at each corner of the chassis. Each holding block 30-1, ..., 30-4 has a through channel in which a lifting column 32-1, ..., 32-4 is guided.

[0039] As in Fig. As shown in Figure 3, the height of the lifting columns 32-1, ..., 32-4 can be adjusted by means of drive shafts 34-1, 34-2, which are driven by associated motors 36-1, 36-2.

[0040] The Fig. Figure 3 also shows further details of the telescope system 18.

[0041] As in Fig. As shown in Figure 3, the telescopic system 18 has at least one guide rail 38-1, 38-2, which is attached to the base plate 22 such that its direction of travel is oriented towards the sides of the shuttle vehicle 10. Guide rollers 40-1, 40-2 are provided on the upper sides of the guide rails 38-1, 38-2.

[0042] As in Fig. As shown in Figure 3, the telescopic system 18 additionally features a movable loading platform 42 along the guide rails 38-1, 38-2, which has a cross-sectional profile with lateral U-shaped sub-profiles. The U-shaped sub-profiles are arranged so that they engage with the guide rollers 40-1, 40-2 to guide the loading platform 42 during movement.

[0043] As in Fig. As shown in Figure 3, the loading platform is moved in and out by means of a drive for extending and retracting the loading platform 42 relative to the shuttle vehicle 10 along the at least one guide rail 38-1, 38-2. According to Fig. 3 is an option for driving a chain conveyor. For this purpose, a conveyor chain 44 is guided along two gears 46-1, 46-2.

[0044] As in Fig. As shown in Figure 3, the shuttle vehicle 10 can be equipped with a double-belt conveyor system, for which a drive motor is also provided. Preferably, two conveyor belts of the double-belt conveyor system are provided along each of the longitudinal sides of the loading surface 42 of at least one telescopic system 18. Furthermore, the running surfaces of the double-belt conveyor system are preferably spaced apart relative to the surface of the loading surface 42 of the telescopic system 18 by a predetermined distance greater than zero. This distance can, for example, have a value of 5 mm to 2 cm.

[0045] Furthermore, it should be noted that, within the scope of the present invention, any number of belt conveyors can generally be used, depending on the requirements. Moreover, these are actuated by a drive provided for this purpose. This can, for example, be an electric motor (in Fig. 3 not shown).

[0046] The shuttle vehicle 10 of the present invention also includes a controller. Preferably, the controller is supplied with data relevant to the movement sequence and the charging process, provided by an external control system of the racking system, via a wireless communication interface, e.g., WLAN.

[0047] For the power supply of the electrical consumers of shuttle vehicle 10, an energy storage system, for example in combination with capacitor storage technology, can be provided. Alternatively, power can be supplied via a conductor rail along a travel path of shuttle vehicle 10.

[0048] The Fig. Figure 4 shows a bottom view of the shuttle vehicle 10 according to the invention.

[0049] As in Fig. As shown in Figure 4, a further chain mechanism 48 is provided on the underside of the shuttle vehicle 10, which corresponds to a gear provided on the underside of the gear 46-1, 46-2. Fig. 4 concealed by means of the cover 50 - engages. In addition, a further gear 52 is provided, which engages via a Fig. The drive 54 shown in section 4 is designed to be rotatable in order to thereby move the drive in Fig. to operate the 3 chain conveyors 44, 46-1, 46-2 shown.

[0050] The Fig. Figure 5 shows another perspective view of the shuttle vehicle 10 according to the invention with the telescopic system 18 extended.

[0051] As in Fig. As shown in Figure 5, goods can be transported in load carriers 20-1, 20-2 with a predetermined length, height, and width. In this case, the loading surface 42 of the telescopic system 18 has a length that is twice the length and / or width of the load carriers 20-1, 20-2 when stored in a double-deep position.

[0052] As in Fig. As shown in Figure 5, the shuttle vehicle 10 is equipped with a single-acting telescopic system 18, which can be extended to the right or left. Single-acting here means extending in one plane to achieve a minimal overall height.

[0053] As in Fig. As shown in Figure 5, when the telescope 18 is extended, a minimum overlap of the telescope system 18 with the shuttle vehicle 10 must be maintained so that any tilting forces that occur can be absorbed.

[0054] According to the invention, by combining a telescopic system 18 with a lifting drive, any number of containers can be stored in an angle rack with a low overall height, the only limitation being the length of the telescopic system 18.

[0055] According to the present invention, the shuttle vehicle 10 can also have a variable number of telescopic systems 18 which can be operated independently of each other.

[0056] Fig. Figure 6 shows a side view, a top view, and a front view of a shuttle vehicle according to the invention positioned in a racking system according to the invention.

[0057] As in Fig. As shown in Figure 6(A), the storage boxes of the racking system according to the invention have recesses 56 in the guide rails so that the telescopic system 18 of each shuttle vehicle 10-1, 10-2 can be extended and retracted relative to the storage boxes.

[0058] As in Fig. As shown in Figure 6(B), each storage box has support surfaces 58, the spacing of which is determined by the dimensions of the storage containers 20-1 and 20-2. Preferably, the support surfaces are designed as angle rails to provide lateral support for the storage containers 20-1 and 20-2 after they have been inserted.

[0059] As in Fig. As shown in Figure 6(C), the support surfaces 58 of the racking system are positioned higher than the rails of the shuttle passage within the racking system. Accordingly, the storage containers 20-1 and 20-2 are placed by lifting them, moving them into the racking, and then lowering the telescopic system 18. As mentioned above, this can be achieved either by raising the telescopic system 18 relative to the chassis of the shuttle vehicle 10, or by raising the entire shuttle vehicle 10 so that the loading platform of the telescopic system is positioned higher than the support surfaces 58 of the racking system.

[0060] Fig. 7 a perspective view of a shuttle vehicle according to the invention positioned in a racking system according to the invention 10.

[0061] As in Fig. As shown in Figure 7, the racking system according to the invention has at least one storage level in which a plurality of storage boxes are arranged at right angles. The racking system provides at least one shuttle passage per level, extending in a straight line between opposite outer sides of the racking system, with guide rails 60-1, 60-2 running along the storage boxes of this storage level. Furthermore, the shuttle vehicle 10 according to the invention can be moved along the guide rails 60-1, 60-2 of the shuttle passage in the at least one shuttle passage of the storage system for storing and retrieving goods.

[0062] As in Fig. As shown in Figure 7, L-shaped and parallel retaining rails 58 are provided for each storage box, the spacing of which is greater than the width of the loading platform 42 of the telescopic system 18. This allows the loading platform to be moved vertically between the retaining rails 58 when the height of the loading platform 42 is changed, in order to raise and lower the loading containers 20-1, 20-2 relative to the retaining rails 58 and subsequently extend or retract the telescopic system 18, depending on whether the loading containers 20-1, 20-2 are being stored or retrieved.

[0063] As in Fig. As also shown in Figure 7, the cross-section of the guide rails 60-1, 60-2 of each shuttle passage has a mounting surface 62-1, 62-2, which is a counterpart to a counter-mounting surface 28 - shown in Figure 7. Fig. 3 - of the shuttle vehicle 10. This prevents the shuttle vehicle 10 from tipping over when the telescopic system 18 of the shuttle vehicle 10 is extended, by creating a connection between a mounting surface 62-1, 62-2 and the counter mounting surface 28.

[0064] The Fig. Figure 8 shows a top view of a racking system according to the invention, which is operated together with at least one shuttle vehicle 10 according to the present invention.

[0065] As in Fig. As shown in Figure 8, the racking system 64 contains at least one storage level in which a large number of storage boxes are arranged at right angles.

[0066] As in Fig. As shown in Figure 8, the racking system 64 contains at least one shuttle passage 66-1, 66-2 per storage level, running in a straight line between opposite outer sides of the racking system 64 and extending along the storage boxes of each storage level.

[0067] Furthermore, the racking system 64 according to the present invention includes at least one shuttle vehicle 10, as shown in the invention. Fig. 1, Fig. 2 to Fig. 3 described. The shuttle vehicle 10 can be moved in the at least one shuttle passage 66-1, 66-2 of the storage system 64 in order to store and retrieve goods using the telescopic technology according to the invention.

[0068] As in Fig. As shown in Figure 8, at least one lift system 68-1, 68-2, 68-3, 68-4 is provided on the outer sides of the racking system 64 in order to move a shuttle vehicle 10 and / or stored goods vertically relative to the individual storage levels of the racking system 64.

[0069] As in Fig. As shown in Figure 8, at least one transfer or lift system 68-1, 68-2, 68-3, 68-4 serves a pre-zone 70 of the racking system 64. Opposite the lift system, a supply and a discharge conveyor system 72 are arranged.

[0070] The Fig. Figure 9 shows a perspective view of the shelving system according to the invention.

[0071] As in Fig. As shown in Figure 9, the transfer or lift systems 68-1, 68-2, 68-3, 68-4 are each provided at the end of a shuttle passage. Shuttle vehicles 10 can be transported between levels of the racking system 64 or to the pre-zone 70 using the transfer or lift systems 68-1, 68-2, 68-3, 68-4. According to the invention, a combination of product transfer systems and shuttle transfer systems can also be used. Since flow channels can be loaded along the longitudinal side of the racking system 64, an advantage arises in that it also enables the possibility of combining the system with standardized goods for personnel picking stations.

[0072] Furthermore, according to the invention, shuttle vehicles 10, including stored goods, can be transferred from the transfer or lift systems 68-1, 68-2, 68-3, 68-4. Several shuttle vehicles 10 can be used per level of the racking system 64. A combination of product and shuttle vehicle transfer is also possible.

[0073] With regard to the in Fig. The standardized process for the shelving system 64 shown in section 9 is as follows: The shuttle transfer system or lift system transports shuttle vehicle 10 to pre-zone 70. There, shuttle vehicle 10 picks up the product to be stored. The transfer or lift system 68-2, 68-4 transports shuttle vehicle 10 with the product to the correct logistical level, where shuttle vehicle 10 enters the level and then places the product in the designated storage box. The reverse process can be used for retrieval.

[0074] By providing multiple lift systems, a route-optimized and redundant approach can be ensured.

[0075] As in Fig. As shown in Figure 9, a further advantage of the present invention lies in the combination of the storage function with the picking function directly on the basis of the racking system 64 and / or a separate arrangement on the racking system 64. This fulfills increasing requirements in the context of Industry 4.0 system solutions with regard to storage, buffering, picking, and for an optimal solution for higher-level communication via WLAN. The shuttle technology according to the invention is characterized by lower energy consumption and a very product-friendly solution.

[0076] In the pre-zone 70, after the lift has moved it to the correct height position, the shuttle vehicle 10 can transfer the stored goods to the conveyor system on one side and pick up the goods from the conveyor system on the other side. This transfer is carried out using telescopic technology or, if required, via a chain conveyor mounted on the shuttle vehicle 10. Conveyor system connections can be configured in multiple stacked configurations or on a single side. Connections on both ends of the racking or along the racking system 64 at the location of a storage position for transferring goods to a shuttle vehicle 10 are also possible.

[0077] According to the invention, if a very high throughput is required on one side of the racking system 64, one or more lift systems can be provided for transferring the load. In this case, shuttle vehicles 10 on the respective levels simply transport the load to the defined transfer station, preferably at the end of the shuttle passages.

[0078] From there, the containers, products, etc. are brought to the pre-zone 70 with the conveying technology for incoming and outgoing materials by means of lift systems designed as load transfer systems.

[0079] The present invention also allows for the transfer of the shuttle vehicles 10 from one shuttle passage to another in a horizontal direction.

[0080] According to the invention, one or more order picking flow racks can be combined with the racking system 64. This results in a particularly advantageous control of the overall system in terms of storage and material flow. Likewise, the number of shuttle vehicles 10 used within the racking system can be variably determined depending on the throughput requirements.

[0081] If order picking flow racks are arranged along the racking system 64, these are filled at the top, i.e., the aisle side, by shuttle vehicle 10. At the bottom, products can be removed from the containers or the load carriers directly. Empty load carriers can be returned via a flow rack section descending towards the shuttle passage. At the bottom end, the load is then transferred by shuttle vehicle 10 using the telescopic undercarriage. If the interface to shuttle vehicle 10 is implemented using a powered conveyor system, the load can be transferred to shuttle vehicle 10 using a double belt conveyor system.

[0082] For order picking, flow racks are equipped with display systems such as "pick-by-light" or "pick-by-voice".

[0083] Overall, the present invention enables the use of a very low-profile, simple-acting undercarriage telescopic mechanism which, in combination with a racking system 40, allows for multi-deep storage. Furthermore, a flow rack can be actively operated for loading and unloading using telescopic system 18. As a result, the present invention achieves multi-deep storage through the telescopic system 18, which can be raised and lowered via a lifting system on the shuttle vehicle 10.
