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 heavy loads.

[0002] In existing storage systems, industrial trucks and storage and retrieval machines form the basis for loading and unloading items from storage locations within a storage system.

[0003] However, such industrial trucks and storage and retrieval machines regularly require a lot of space and are limited in terms of storage depth.

[0004] Furthermore, such industrial trucks regularly require additional space for maneuvering, so their use leads to a reduction in the storage capacity available.

[0005] German patent DE 32 07 860 A1 describes a conveying system for a warehouse facility, consisting of a trolley (23) equipped with at least two independently operable lifting platforms (27, 28) for picking up and setting down load units. The trolleys (23), each piggybacked on a carrier trolley (24), are movable on rails (25, 26) in the storage areas (4) and run directly beneath the load units. Each carrier trolley (24) and the trolley (23) it carries together form a horizontal transport unit, which may be transported with a load unit by the elevator (8) between the floors (3) and the transfer station (9) and can move freely independently of the elevator on the floors (3).By dividing the load handling device on the undercarriage (23) into at least two load-compatible lifting platforms (27, 28), more efficient storage strategies are achieved for the mixed storage of load units with at least two different sized base areas.

[0006] Furthermore, DE 10 2016 105 677 A1 describes a shuttle for the storage and retrieval of cargo, in which the cargo or load units (6) are arranged on at least one platform or support (8.2) and a lifting mechanism (9) is assigned to this as a connection to a base (8.1), and the length of the base (8.1) or the distance between two structural elements (10.1 and 10.2) of the base (8.1) is to be variable for actuating the lifting mechanism (9).

[0007] Finally, DE 43 27 382 A1 describes a high-bay warehouse with a distribution vehicle.The invention relates to a high-bay warehouse with a storage and retrieval machine and a distribution vehicle that is horizontally movable therein and serves for loading in depth, wherein the storage and retrieval machine is provided with vertically movable profile rails that are parallel to each other and also horizontally aligned and run parallel to the shelf levels, in which the distribution vehicle is guided, which in turn has rotatable wheels, a telescopic fork for picking up, transporting and placing pallets loaded with stored goods and an electric motor as a drive, and proposes that the electric motor (6) drives a hydraulic oil pump (4), and that the hydraulic oil pump (4) is connected via controllable valves to cylinders (5) that drive the telescopic fork (7) and the wheels (2), wherein the valves are provided with a control that activates the individual types of movement of the telescopic fork (7) and the wheels essentially successively.

[0008] Accordingly, the technical problem of the present invention lies in increasing the flexibility and throughput of a storage system.

[0009] According to the present invention, this technical problem is solved with a shuttle vehicle according to claim 1.

[0010] The shuttle vehicle according to the invention can be moved within the racking system for transporting stored goods. The shuttle vehicle comprises a chassis with wheels mounted on it for moving the shuttle vehicle along guide rails of the racking system. Furthermore, the shuttle vehicle comprises at least one telescopic guide rail which is mounted on the chassis such that its direction of travel deviates from that of the guide rails of the racking system by a predetermined angle greater than zero, e.g., an angle of substantially 90°.

[0011] In addition, the shuttle vehicle includes a telescopic system for each telescopic track with telescopic wheels mounted on it, in order to extend and retract the telescopic system along the associated telescopic track relative to the chassis in one plane.

[0012] Furthermore, the technical problem of the present invention is solved by a shelving system according to claim 9.

[0013] The racking system has at least one storage level in which a plurality of storage locations, storage positions, or rack positions are arranged at right angles. The racking system also has at least one shuttle passage per storage level, running between opposite outer sides of the racking system. The shuttle passage runs in a straight line along the storage locations of the storage level. Furthermore, the racking system has at least one shuttle vehicle according to the invention, which can move in at least one shuttle passage of the storage system for storing and retrieving goods.

[0014] Further advantageous embodiments of the present invention are specified in the dependent claims.

[0015] 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 telescope system according to the invention; Fig. 3 a perspective view of the shuttle vehicle according to the invention with extended telescopic system in case of multiple deep storage of transport containers; Fig. 4 the use of the shuttle vehicle according to the invention in a storage system according to the invention; Fig. 5 a top view of a bearing system according to the invention; Fig. 6 a perspective view of the bearing system according to the invention; and Fig. 7 a perspective view of the storage system according to the invention with picking flow racks.

[0016] 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).

[0017] As in Fig. As shown in Figure 1, the shuttle vehicle 10 is used to transport stored goods in a racking system. It includes a chassis 12 with wheels 14-1, 14-2, 14-3, 14-4 mounted on it to move the shuttle vehicle along rails 16-1, 16-2 of the racking system.

[0018] As in Fig. 1 (A) and in Fig. As shown in Figure 1(B), the shuttle vehicle 10 includes at least one telescopic guide rail 18-1, 18-2, which is mounted on the chassis 12 such that its direction of travel differs from that of the guide rail 16-1, 16-2 of the racking system by a predetermined angle greater than zero. For example, this angle has a value of essentially 90°, so that the directions of travel of the guide rails 16-1, 16-2 extend to the opposite sides of the shuttle vehicle 10. However, according to the present invention, it is also possible to choose a smaller or larger value for the angle in order to achieve an oblique exit direction relative to the guide rails of the racking system.

[0019] As in Fig. 1 (A) and Fig. As shown in Figure 1 (B), the shuttle vehicle 10 also has a telescopic system 20 with telescopic wheels 22-1, 22-2, 22-3, 22-4 mounted thereon, in order to extend and retract the telescopic system 20 along the associated telescopic guide rail or the associated vehicle rails 18-1, 18-2 relative to the chassis 12 in one plane.

[0020] According to the present invention, the telescopic system 20 is of single-acting design. This means that the telescopic arm is a single-section unit and can therefore be moved in one plane. This results in a generally very low profile for the shuttle vehicle, which is of particular importance for increasing efficiency in the racking system.

[0021] Furthermore, within the scope of the present invention, the shuttle vehicle 10 is designed as a heavy-duty shuttle vehicle.

[0022] In the heavy-duty version, the extending and retracting telescopic system 20 runs on assigned guide rails, which are provided in the bearing system to absorb the forces acting by the load of the telescopic system 20.

[0023] For the operation of the telescopic system 20, an associated drive can be provided on the shuttle vehicle 10, for example a chain drive. Alternatively, the telescopic system can be equipped with its own drive, for example an electric motor, which increases flexibility because there are no restrictions with regard to the insertion depth into the racking system.

[0024] According to the invention, the combination of the chassis 12 and the telescopic system 20 makes it possible to carry out multi-deep storage in any variability.

[0025] Depending on the shelf's depth, multiple storage depths are possible. Therefore, if the reach of the telescopic system equals the storage depth, single-deep storage is achieved. Similarly, if the reach of the telescopic system equals twice the storage depth, double-deep storage is achieved, and so on.

[0026] As in the Fig. 1 (A) and Fig. As shown in Figure 1 (B), for example, two storage units 24-1, 24-2 can be used in a double-deep storage system. Shuttle vehicles use the telescopic system 20 to load or unload storage containers from the storage system.

[0027] In the heavy-duty version, the telescopic system 20 stores and retrieves the load using telescopic undercarriage technology.

[0028] In the heavy-duty version, the wheels 22-1, 22-2, 22-3, 22-4 of the telescopic system 20 run in guide rails of the racking system in order to be able to bear large loads.

[0029] In the heavy-duty version, the vehicle shuttle 10 can support a weight of approximately 15 tons and store items up to 6 meters deep. Narrow and wide products, such as stacks of chipboard, can be stored in multiple depths. For example, with single-deep storage, items up to 5.7 meters long, 2.1 meters wide, and 0.9 meters high can be stored, weighing approximately 15 tons. With double-deep storage, items up to 2.8 meters long, 2.1 meters wide, and 0.9 meters high can be stored, each weighing approximately 4.5 to 7.5 tons. With quadruple-deep storage, items can be stored two deep and two side-by-side, each 2.8 meters long and 1.1 meters wide. In the latter case, two packages can be stored side-by-side and two behind each other, allowing space for four items per storage box.

[0030] Furthermore, according to the shuttle technology of the invention, dynamic rack storage and order picking applications for heavy products up to 15t can be handled, depending on the industry, whereby a telescopic arm 20 is used to access, lift, and retrieve or store the products. Shorter packages can be stored one after the other. The depth of access is variable, so that the required depth can be reached for storage and retrieval. For example, if only the third of three packages is needed, packages 1 and 2 can be stored on the opposite side.

[0031] Furthermore, the shuttle technology according to the invention achieves a higher throughput with a large number of shuttle vehicles compared to conventional racking systems, as parallel operation enables a higher throughput. As explained in more detail below, several shuttle vehicles can be used per level of a racking system, which can be moved vertically between individual levels of the racking system by means of shuttle transfer units. The transfer units can be arranged on one or both sides of the racking system. The shuttle vehicles are moved with or without a load using the transfer units. Alternatively, only products can be moved; in this case, one transfer unit for shuttles at one end of the racking system and another transfer unit for products only at the other end or along the racking system would be a possible implementation.

[0032] The Fig. Figure 2 shows a perspective view of the telescope system 20 according to the invention.

[0033] As in Fig. As shown in Figure 2, the telescopic system 20 includes a base support element 26 to which the wheels 22-1, 22-2, ... are attached by means of wheel suspensions 28-1, 28-2, ... . The telescopic system 20 also has a loading platform 30 attached to the base support element 26. Preferably, the wheel suspensions 28-1, 28-2, ... are designed such that the wheels 22-1, 22-2, ... can pivot along the direction of travel of the telescopic system 20.

[0034] As in Fig. As shown in Figure 2, the telescopic system 20 also features a lifting system by means of which the loading platform 30 is attached to the base support system 26 in a height-adjustable manner. The lifting system is formed by several X-braces attached to the base support element 26 and to the loading platform 30, and several lifting columns 36 for positioning the loading platform 30 relative to the base support element 26. The operation of the lifting system can be mechanical, electrical, and / or hydraulic.

[0035] Furthermore, the design of the lifting system is not limited to an X-brace. Options also include linear lifting elements, eccentric lifting elements, or crank drives.

[0036] The Fig. Figure 3 shows a perspective view of the shuttle vehicle 10 according to the invention with double deep bearing when the telescopic system 20 is extended.

[0037] As in Fig. As shown in Figure 3, goods can be transported in load carriers 24-1, 24-2 with a predetermined length, height, and width. The loading surface 30 of the telescopic system 20, in the case of single-deep storage, has a length that is a multiple of the length or width of the load carriers, in particular a multiple of the length or width of the load carriers 24-1, 24-2.

[0038] As in Fig. As shown in Figure 3, in the heavy-duty version the telescopic wheels 22-1, 22-2, ... of the telescopic system 20 can rest in corresponding telescopic guide rails of the bearing system.

[0039] According to the invention, the storage and retrieval process is carried out using the telescopic system 20 of a shuttle vehicle 10 in a raised position. Subsequently, containers 24-1 and 24-2 are lowered onto a storage position of the racking system, and the telescopic system 20 is retracted after lowering.

[0040] As in Fig. As shown in Figure 3, the shuttle vehicle 10 is equipped with a single-acting telescopic system 20, which can be extended to the right or left. Single-acting here means extending in one plane to achieve a minimal overall height. The shuttle vehicle 10 according to the invention also has drive motors 38-1, 38-2, 38-3, 38-4 assigned to the wheels 40-1, 40-2, 40-3, 40-4 of the chassis 12. In addition, a drive motor for the lifting mechanism (if the lifting system is electrically operated) and a drive motor for the telescopic system 20 are provided.

[0041] Alternatively, the conveyor system could consist of several conveyor strands, e.g. four conveyor strands, depending on the load and weight, using chain, toothed belt, etc.

[0042] Furthermore, 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 platform 30 of at least one telescopic system 20. In addition, the running surfaces of the double-belt conveyor system are preferably positioned relative to the surface of the loading platform 30 of the telescopic system 20 at a predetermined distance greater than zero. This distance can, for example, have a value of 5 mm to 5 cm.

[0043] For conveyor technology, another option is the use of chain conveyors, toothed belts or conveyor belts.

[0044] As in Fig. As shown in Figure 3, by combining a telescopic system 20 with a lifting drive in a single-acting manner with a low overall height, any number of goods can be stored in an angle rack, with the only limitation being the length of the telescopic system 20.

[0045] Likewise, the shuttle vehicle 10 of the present invention 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.

[0046] 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.

[0047] According to the present invention, the shuttle vehicle 10 can have a variable number of telescopic systems 20 which can be operated independently of each other.

[0048] Fig. Figure 4 shows the use of the shuttle vehicle according to the invention in a storage system according to the invention.

[0049] The Fig. Figure 4 shows more clearly the positioning of the shuttle system 10 according to the invention relative to a storage box 32 of the racking system.

[0050] As in Fig. As shown in Figure 4, the shuttle vehicle 10 approaches the storage box 32 in such a way that the guide rails 18-1 and 18-2 of the shuttle vehicle 10 align with the corresponding guide rails of the storage box 32. Once this alignment is achieved, the shuttle vehicle 10 stops and the telescopic system 20 can enter the storage box 32. This allows for multi-deep storage. Fig. 4 a double-deep storage system, limited only by the length of the telescopic system 20. Furthermore, the heavy-duty variant can be realized within the scope of the present invention, since the load and the resulting forces can be transferred directly into the storage system via the rails of the storage box 32 without any additional forces acting on the shuttle vehicle 10.

[0051] The Fig. Figure 5 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.

[0052] As in Fig. As shown in Figure 5, the racking system 40 contains at least one storage level in which a large number of storage boxes are arranged at right angles.

[0053] As in Fig. As shown in Figure 5, the racking system 40 contains at least one shuttle passage 42-1, 42-2 per storage level running in a straight line between opposite outer sides of the racking system 40 and extending along the storage boxes of each storage level.

[0054] Furthermore, the racking system 40 according to the present invention includes at least one shuttle vehicle 10, as shown in the invention. Fig. 1 to Fig. 3 described. The shuttle vehicle 10 can be moved in the at least one shuttle passage 42-1, 42-2 of the storage system 40 in order to store and retrieve goods using the telescopic technology according to the invention.

[0055] Furthermore, according to the invention, the storage boxes are provided with telescopic guide rails on their underside, so that in heavy load cases, with the telescopic system 20 of the shuttle vehicle 10 extended, the telescopic wheels 22-1, 22-2, 22-3, 22-4 rest on these telescopic guide rails. Additionally, power rails can be provided in each shuttle passage 42-1, 42-2 to supply the shuttle vehicle 10 with energy.

[0056] As in Fig. As shown in Figure 5, at least one transfer or system 44-1, 44-2, 44-3, 44-4 is provided on the outer sides of the racking system 40 in order to transfer a shuttle vehicle 10 and / or stored goods vertically relative to the individual storage levels of the racking system 40.

[0057] As in Fig. As shown in Figure 5, a transfer system 44-1, 44-2, 44-3, 44-4 serves a pre-zone 46 of the racking system 40. Opposite the lift system, a feeder and a discharge conveyor system 48 are arranged. Feeding and discharge can take place on multiple levels, allowing for several feeders and discharges to be implemented on one side, opposite each other, or on multiple sides.

[0058] As in Fig. As shown in Figure 5, 40 flow racks 50 can be arranged along the racking system, which can be filled at their top by means of a shuttle vehicle 10 and at their bottom can be taken over by a shuttle vehicle 10.

[0059] The Fig. Figure 6 shows a perspective view of the shelving system according to the invention.

[0060] As in Fig. As shown in Figure 6, transfer systems 44-1, 44-2, 44-3, and 44-4 are each provided at the end of a shuttle passage. These transfer systems enable shuttle vehicles 10 to be transported between levels of the racking system 40 or to the pre-zone 46. 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 40, this offers the advantage of also allowing for combination with standardized goods at personnel picking stations.

[0061] Furthermore, according to the invention, shuttle vehicles 10, including stored goods, can be transferred from the transfer systems 44-1, 44-2, 44-3, 44-4. Several shuttle vehicles 10 can be used per level of the racking system 40. A combination of product and shuttle vehicle transfer is also possible.

[0062] With regard to the in Fig. The 6 shelving system 40 shown results in a standardized process as follows: The shuttle transfer unit or lift system transports shuttle vehicle 10 to pre-zone 46. There, shuttle vehicle 10 picks up the product to be stored. Lift system 44-2, 44-4 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.

[0063] By providing multiple lift systems, a route-optimized and redundant approach can be ensured.

[0064] As in Fig. As shown in Figure 6, a further advantage of the present invention lies in the combination of the storage function with the order picking function directly on the basis of the racking system 40 and / or a separate arrangement on the racking system 40. This fulfills the increasing requirements in the context of Industry 4.0 system solutions with regard to storage, buffering, order 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.

[0065] Optionally, training courses for the Shuttle Vehicle 10 with and without chain conveyors are also possible, which allow cargo to be transported onto the loading platform.

[0066] In the area of ​​the pre-zone 46, the shuttle vehicle 10, after the lift has transported it to the correct height position, can transfer the stored goods to the conveyor system 48 on one side and pick up the goods from the conveyor system 48 on the other side. This transfer and pickup is carried out using telescopic technology or, if required, by means of 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 40 at the location of a storage position for transferring goods to a shuttle vehicle 10 are also possible.

[0067] According to the invention, if a very high throughput is required, a lift system or several lift systems can be provided on one side of the racking system 40 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 42-1, 42-2.

[0068] From there, the containers, products, etc. are then brought to the pre-zone 46 with the conveying technology 48 for incoming and outgoing materials by means of lift systems designed as load transfer systems.

[0069] The present invention also allows for the transfer of the shuttle vehicles 10 from one shuttle passage to another in a horizontal direction, both in the heavy load variant and in the low load variant.

[0070] Fig. Figure 7 shows a perspective view of the storage system according to the invention with picking flow racks.

[0071] As in Fig. As shown in Figure 7, according to the invention, one or more picking flow racks can be combined with the racking system 40. This results in a particularly advantageous storage and material flow control of the overall system. Likewise, the number of shuttle vehicles 10 used within the racking system can be variably determined depending on the throughput requirements.

[0072] If order picking or the transport of goods to and from the racking system 40 is equipped with flow racks for order picking or for the loading and unloading of goods, these are filled at the top, i.e., the aisle side, by the shuttle vehicle 10. Products can be removed from the containers or packages or directly from the bottom. Empty load carriers can be returned via a flow rack section that slopes down towards the shuttle passage. At the bottom, the goods are then picked up again by the shuttle vehicle 10 using the telescopic undercarriage. Goods can also be transported from one racking system to another in this way, optionally also using powered conveyor technology. If the interface to the shuttle vehicle 10 is implemented using powered conveyor technology, the goods can be transferred to the shuttle vehicle 10 using a double belt conveyor system.

[0073] For order picking, flow racks are equipped with display systems such as "pick-by-light" or "pick-by-voice". Fully automated order picking using robotics is also possible.

[0074] 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 the telescopic system 20. As a result, the present invention achieves multi-deep storage through the telescopic system 20, which can be raised and lowered via a lifting system on the shuttle vehicle 10.
