Description

1. Field of the invention

[0001] The invention relates to load-handling devices with telescopic tables arranged thereon, the length of which is adjustable in a first direction and in a second direction opposite to the first direction. Furthermore, the invention relates to a method for carrying and transporting a load with a load-handling device with telescopic tables arranged thereon. Finally, the invention relates to a system comprising a load-handling device and a storage and retrieval machine, as well as a high-bay warehouse with a storage and retrieval machine. 2. State of the art

[0002] Load-handling devices of the type in question are used in particular in storage and retrieval machines (SRMs) designed and configured to move along rails in the aisles of high-bay warehouses. These SRMs incorporate lifting platforms as an example of load-handling devices, on which two telescopic tables are mounted, adjustable in length. The telescopic tables are connected to the load, either by placing the load on the telescopic tables or by attaching the telescopic tables to the load from above, in order to then support and transport it suspended. Typically, during the movement of the SRM along the aisle and the vertical movement of the lifting platform within the SRM to the height of a storage location within the high-bay warehouse, the telescopic tables are retracted so that they preferably do not increase the overall width of the SRM.This allows for the narrowest possible design of the racking aisles and thus of the high-bay warehouse as a whole. Once the lifting platform reaches the point in front of the storage location, the telescopic tables are extended together with the load, so that the load, preferably a standard shipping container, can be moved into the racking location and then placed there. Once the load has been set down, the telescopic table and the load are separated, and the telescopic table is retracted to its original extension, so that the storage and retrieval machine can then move freely within the racking aisle, either to pick up another load from outside, from an external transport vehicle, or from a transport vehicle within the high-bay warehouse itself, such as a mobile pallet, or to pick up another load from a preferably separate storage location within the high-bay warehouse, from where it can then be transported further.

[0003] An example of a storage and retrieval machine for a high-bay warehouse can be found in DE 10 2021 117 938 A1.

[0004] The load handling devices, and in particular the lifting platforms of storage and retrieval machines, are typically designed and configured to accommodate loads of defined lengths. In the case of shipping containers, these are either 20-foot or 40-foot standard containers, and especially in the USA, also 45-foot or 53-foot standard containers, which can typically weigh up to 40 tons. Particularly large loads weighing more than 20 tons are usually transported in 20-foot standard containers. High-bay warehouses of this type have storage locations or entire rack sections specifically designed to accommodate these 20-foot, 40-foot, 45-foot, or 53-foot standard containers.

[0005] The load-handling devices are designed for heavy loads and have components that, due to the required rigidity, also have a considerable weight. Telescopic tables for loads of 20 tons or more typically weigh around seven tons. It is therefore not economically feasible to use load-handling devices, and especially stacker cranes with corresponding lifting platforms, that incorporate a large number of telescopic tables to flexibly handle or carry loads of varying lengths. 3. Object of the invention

[0006] It was therefore an object of the invention to provide a load-handling device with telescopic tables arranged thereon, as well as a method for carrying and transporting a load with such a load-handling device, which can flexibly accommodate and safely transport loads of different dimensions while simultaneously minimizing the material usage and the weight of the load-handling device. This object is achieved according to the invention with a load-handling device comprising the features of claim 1, as well as with a system according to claim 21 and a high-bay warehouse according to claim 23, with a method comprising the features of claim 17. Advantageous embodiments of the invention are set forth in particular in the dependent claims. 4. Summary of the invention

[0007] According to a first aspect of the invention, a load-handling device is provided with telescopic tables arranged thereon, the lengths of which are adjustable in a first direction and a second direction opposite to the first direction. The load-handling device is characterized in that at least two telescopic tables are connected to the load-handling device, the distance between which, preferably the distance perpendicular to the first and the second direction, is variable.The invention according to the first aspect thus relates to a load-handling device in which the distance between the telescopic tables is designed to be variable so that loads of different dimensions can be safely picked up and transported without having to keep telescopic tables that are fixed to the load-handling device at the optimal distance in order to increase its flexibility in transporting loads of different dimensions.

[0008] In a preferred embodiment of the invention, at least three telescopic tables are connected to the load-handling device, at least two of which are arranged on the load-handling device so that their distance from each other is adjustable. Usually, the adjustability of two telescopic tables relative to each other is sufficient to achieve the desired flexibility of the load-handling device; however, in special cases, it can also be advantageous if three out of three, three out of four, or generally all telescopic tables on the load-handling device are adjustable in their distance from each other. This creates a load-handling device that offers particularly high flexibility with regard to its range of applications while simultaneously requiring minimal material and having minimal weight.

[0009] In a further preferred embodiment of the invention, the load-handling device is a lifting platform arranged vertically within a frame. It is particularly preferred if the lifting platform constitutes a vertically movable part of a storage and retrieval machine, preferably rail-guided, within a high-bay warehouse. It is highly preferred if the lifting platform is vertically movable by means of a cable drive, whereby the vertical movement of the lifting platform can be achieved even with heavy loads using particularly simple and easily controllable means. The use of the load-handling device as a lifting platform within a frame, particularly a storage and retrieval machine, allows for the particularly flexible use of telescopic tables, a particularly narrow installation space in the storage aisles, and thus in the entire high-bay warehouse.

[0010] Preferably, each telescopic table has a base part connected to the load-bearing element and at least one sliding part arranged within and / or on the base part so as to be displaceable in a first direction and a second direction opposite to the first direction. This particularly benefits the principle of the telescoping of the telescopic table and simultaneously increases the overall rigidity of the construction. If flexible telescoping or a particularly long telescoping stroke is desired, the telescopic table according to the invention can also have a base part, an intermediate part displaceable with the base part, and an end part displaceable on the intermediate part as a sliding part.

[0011] It is also preferred if the telescopic tables are arranged to be directly slidable on the load-handling device, wherein the slidability can be adjusted, for example, by the action of corresponding hydraulic cylinders on the respective telescopic tables, by chain drives, or by means of electric motors. In an alternative and equally preferred embodiment of the invention, at least two telescopic tables are rigidly connected to a support structure, preferably a frame structure, which is slidably connected to the load-handling device. In any case, precise and reproducible displacement of the telescopic tables is achieved using commercially available and easily controllable means, wherein the arrangement of the telescopic tables on sliding frames is particularly advantageous for loads that are centered and, if necessary,The load is supported not only by the telescopic tables, but also on two opposite sides by the frame structure itself, creating double or triple height support. The frame structure and the indirect connection of the telescopic tables to the load-handling device via the frame structure are particularly advantageous when the telescopic tables are designed and configured to grip the load-handling device from below. In this case, the problem of the load detaching from the telescopic tables, the effects of mechanical shocks, or the shifting of the load's center of gravity, for example during transport with the load-handling device, is significantly higher than in the case of telescopic tables designed and configured to support and transport the load while suspended.

[0012] As mentioned above, it is preferred that the distance between at least two telescopic tables be adjustable so that containers with standard lengths of 20, 40, 45, and 53 feet can be supported or carried by the telescopic tables. This means that the distance between the telescopic tables can be changed so that they can be positioned under the standardized support points on the underside of 20-foot and 40-foot or 45-foot and 53-foot shipping containers, and also above the twistlock bolt receptacles usually provided at the corners.

[0013] As mentioned at the outset, in an alternative embodiment, the telescopic tables can be configured and designed to support or bear the load from both below and above. If the telescopic tables are intended to support the load from below, it is preferred that each telescopic table be connected to attachments extending parallel to the orientation of the distance from a first telescopic table towards a second telescopic table. In this context, it is particularly preferred if at least two telescopic tables are each connected to an attachment that extends parallel to the orientation of the distance and parallel to, and spaced apart from, another attachment.This creates a load-bearing device that provides a support structure for the load. This structure is not only formed by the telescopic tables, but also covers the otherwise free space between the telescopic tables, at least partially and preferably over the entire length of the distance, with the attachments. It is particularly preferred if the attachments of two spaced-apart telescopic tables are oriented towards the adjacent telescopic table and, ideally, are arranged to interlock or intermeshing like two opposing rakes or forks when the distance between the telescopic tables is reduced. All of this serves the purpose of creating a load-bearing device design that is flexible both in terms of area and the spacing of the support points for the load, and achieving this goal with simple yet effective means.

[0014] If the telescopic tables are designed and configured to support the load, preferably standard shipping containers, from above, it is preferred that the telescopic tables are each equipped with appropriate fastening means, particularly preferably twistlock bolts, which can be joined together in corresponding bolt receptacles that are usually provided in the corner areas of the containers. In this context, it is particularly preferred if the twistlock bolts are connected to and arranged on the telescopic tables in such a way that they have degrees of freedom in more than one spatial direction, in order to compensate for positional and / or manufacturing tolerances without the need to realign the telescopic tables or the entire load-bearing device.Such freedom of movement in more than one spatial direction can be achieved, for example, by a gimbal suspension of the twistlock bolts or by suspending the individual twistlock bolts via a ball joint on the telescopic tables.

[0015] According to a further aspect of the invention, a method for carrying and transporting a load is provided using a load-handling device with telescopic tables arranged thereon, the lengths of which are adjustable in a first direction and a second direction opposite to the first direction. This method is preferably applicable using a load-handling device according to the first aspect of the invention, whereby the same effects can be achieved as already disclosed above with regard to the first aspect of the invention. The method according to the invention is characterized in that at least two telescopic tables are connected to the load-handling device, the distance between which is varied, preferably the distance perpendicular to the first and second directions.The method according to the invention thus offers the possibility of safely carrying and transporting loads of different lengths or widths with one and the same load-bearing device.

[0016] In this context, it is preferred that the distance between at least two telescopic tables be adjusted to correspond to the distance between two attachment or support points of a load, preferably a 20-foot, 40-foot, 45-foot, or 53-foot standard shipping container, and in particular the distance between two twistlock fittings on a standard shipping container. This provides a method that can be easily adapted to different load dimensions and enables the carrying and transport of loads of varying dimensions with minimal weight and material usage for the load-handling device itself.

[0017] The method according to the invention is preferably defined by the following steps: In a first step, the distance between at least two telescopic tables is changed, followed by a second step in which the telescopic tables are extended telescopically from a first length to a second length until the telescopic tables are positioned below or above the load, preferably a standard shipping container. In a third step, contact between the telescopic tables and the load is then achieved, followed by a fourth step in which the telescopic tables are lifted together with the load, followed by a fifth step in which the load is transported together with the load-handling device to another location, and a sixth step in which the load is set down at this other location.It is particularly preferred if, between the fourth and fifth steps, as described above, the length of the telescopic tables is shortened, preferably retracted completely to their initial state. This ensures that the load is ideally positioned entirely below or above the load-handling device, preferably a lifting platform of a storage and retrieval machine, thereby reducing bending moments that could act on the load-handling device to a minimum, preferably zero, and minimizing the mechanical load acting on the storage and retrieval machine during the vertical transport of the load-handling device and, in particular, the lifting platform.

[0018] The invention is advantageously applicable in a system consisting of a load handling device according to the invention and a storage and retrieval machine, as is used in a high-bay warehouse, in particular container high-bay warehouse, preferably for carrying out the method according to the invention.

[0019] The invention is ultimately advantageously embodied by a high-bay warehouse in which storage and retrieval machines are movable in storage aisles between storage areas, wherein at least one storage and retrieval machine, preferably all storage and retrieval machines, comprise a load handling device according to the invention. 5. Brief description of the characters

[0020] The invention is explained in more detail below with reference to a series of figures illustrating preferred embodiments of the invention. However, these figures are not suitable to limit the scope of protection of the invention, which is defined in the pending claims, in any way. The figures show Fig. 1 in partial figures a) to f) an embodiment of a load-handling device with three telescopic tables, Fig. 2 in the partial figures a) to f) the arrangement of a load-bearing device according to Fig. 1 on a self-driving vehicle, Fig. 3 in partial figures a) to h) shows a further embodiment of a load-bearing device according to the invention with two telescopic tables, and Fig. Figure 4 in sub-figures a) to d) shows an embodiment of a lifting platform as a load handling device with two telescopic tables for the suspended transport of standard sea containers. 6. Detailed description of the figures

[0021] Fig. Figure 1 shows a load-handling device 1 in six views (a) to f). While Figures a), c), and e) show three telescopic sections 2a, 2b, 2c directly connected to a frame 3, which is a lifting platform of a (not shown) storage and retrieval machine for use in a (not shown) high-bay warehouse, Figures b), d), and f) show the same frame 3 with three telescopic sections 2a, 2b, 2c, the spacing Z of which has been changed compared to the configuration shown in Figures a), c), and e). The telescopic sections 2a, 2b, 2c are slidably arranged along rails 8a, 8b on the frame 3 and are also designed to be variable in length in a first direction X. This is achieved by the fact that the telescopic 2a, 2b, 2c each have a base part 2-1 which is connected to the rails 8a, 8b and whose length is not greater or only insignificantly greater than the distance between the rails 8a, 8b.The extension of the telescopic sections 2a, 2b, 2c in the X direction is achieved by the sliding elements 2-2 being slidably arranged within the base sections 2-1, thus allowing the length of the telescopic sections 2a, 2b, 2c to be increased or decreased as needed. The telescopic sections 2a, 2b, 2c are designed to support a load (not shown) from below and then move it, supported from below, in the X direction or in the opposite direction Y. Furthermore, a vertical displacement of the load (not shown) can be achieved by raising the load-bearing device 1. Likewise, a horizontal movement of the load (not shown) can occur if the load-bearing device 1 as a whole can be moved in a horizontal direction.Attachments 7a, 7b, 7c are mounted on the upward-facing upper surfaces of the telescopic tables 2a, 2b, 2c. When the telescopic tables 2a, 2b, 2c are retracted, as shown in Figures a), c), and e), these attachments form a continuous support for a load (not shown) borne by the telescopic tables 2a, 2b, 2c. The attachments 7a, 7c have projections that extend onto the telescopic table 2b and the attachment 7b, while the attachment 7b has complementary receptacles for the projections on the attachments 7a, 7c. In the... Fig. Figures 1b), d), and f) show the telescopic tables 2a, 2b, 2c in a state where the distance between the telescopic tables 2a and 2c is set to its maximum extent within the frame 3 of the load-handling device 1. In this case, a load (not shown) with a longitudinal extent essentially corresponding to the length of the rails 8a, 8b can be supported and lifted from below, as required. Alternatively, the distance Z between the telescopic tables 2a, 2b, 2c can be adjusted so that they engage support points provided on the load (not shown) to effect the lever and transport movement. While in Figures e) and f) all telescopic tables 2a, 2b, 2c are shown in their extended state with the sliding sections 2-2 fully extended, only one or two telescopic tables 2a, 2b, 2c can also be extended to support a load (not shown).

[0022] to telescope the load while the other(s) of the telescopic table(s) do not participate in this load movement operation.

[0023] Fig. Figure 2 shows different views of the load-bearing device 1. Fig. 1, which interacts with a self-driving vehicle 10. The vehicle 10 according to the Fig. 2 a), Fig. 2 c) and Fig. 2 e) each has two pairs of supports 11 a), 11 b) for supporting 20-foot standard sea containers 4. In the Fig. 2 a), Fig. 2 c) and Fig. 2 e) Only one storage space for a standard shipping container 4 is occupied on the vehicle 10. The vehicle 10 is positioned parallel to and next to the load handling device 1. The telescopic tables 2a, 2b, 2c are extended in a first direction X so that the attachments 7a, 7b, 7c are positioned below the container 4. To transfer the load from the vehicle 10 to the load handling device 1, it is sufficient either to raise the load handling device 1, including the telescopic tables 2a, 2b, 2c, to such an extent that the container 4 detaches from the supports 11a, 11b and is then supported exclusively by the telescopic tables 2a, 2b, 2c, or to lower the vehicle 10 to such an extent that the load 4 is also supported exclusively by the telescopic tables 2a, 2b, 2c. The load 4 can then be picked up by the load handling device 1 by retracting the telescopic tables 2a, 2b, 2c in direction Y and transported further by it. Fig. 2 b), Fig. 2 d) and Fig. 2 f) show vehicle 10 in the same configuration as in the Fig. 2 a), Fig. 2 c) and Fig. 2 e), however, loaded with a 40-foot standard shipping container 4, which extends over both pairs of supports 11a, 11b of the vehicle 10. The telescopic tables 2a, 2b and 2c have been modified in their distance Z from each other so that they engage the two outer load support points of the container 4 and, in addition, provide extra support for its center by means of the telescopic table 2b. The transfer function of the 40-foot standard shipping container 4 according to the Fig. 2 b), Fig. 2 d) and Fig. 2 f) functionally corresponds to the transfer function for a 20-foot standard shipping container 4, as used in the Fig. 2 a), Fig. 2 c) and Fig. 2 e) is shown.

[0024] Fig. Figure 3 shows in sub-figures a) to h) a load-handling device 1 with two telescopic tables 2a, 2b arranged on it in various views and configurations of attachments 7a, 7b. The telescopic tables 2a, 2b are connected to the load-handling device 1 such that their distance Z from each other is adjustable. Attachments 7a, 7b are connected to each of the telescopic tables 2a, 2b, extending at least partially from a first telescopic table 2a towards the second telescopic table 2b. In the configuration according to the Fig. 3 a), Fig. 3 c), Fig. In 3 e) and 3 g), the attachments 7a, 7b are each rigidly connected to a telescopic table 2a, 2b and extend parallel to the longitudinal extent of the load-handling device 1 and at different distances from the load-handling device 1 onto the respective other telescopic table 2a, 2b, such that both attachments 7a, 7b bridge at least the distance Z between the telescopic tables 2a, 2b. This creates a continuous support surface for a load (not shown) which is supported from below by the telescopic tables 2a, 2b and the attachments 7a, 7b. Fig. 2 b), Fig. 2 d), Fig. In sections 2 f) and 2 h), the attachments 7a and 7b are designed such that they not only extend towards the respective other telescopic table 2a and 2b, but also extend from a first telescopic table 2a, at least partially away from the second telescopic table 2b. This creates a bearing surface for a load (not shown) that extends outwards over the distance Z between the two telescopic tables 2a and 2b, in order to securely support a load (not shown) from below, the length of which essentially corresponds to the longitudinal extent of the load-bearing device 1.

[0025] Fig. 4 finally shows in the Fig. 4 a), Fig. 4 b), Fig. 4 c) and Fig. 4 d) a load-handling device 1 with two telescopic tables 2a, 2b arranged so as to be displaceable at a distance Z from each other, which are designed and configured to grasp a load 4 from above and suspended from the ground. Fig. 4 a) A 40-foot standard shipping container 4-1 is connected at its corners to the telescopic tables 2a, 2b via (not shown) twistlock bolts, the telescopic tables 2a, 2b being shown in an extended position. The same applies to the Fig. 2 b), in which the telescopic tables 2a, 2b are spaced Z apart from each other opposite to the one in Fig. 4 a) were moved towards each other in the constellation shown, in order to support a 20-foot standard shipping container 4-2 suspended from above in the same manner. In Fig. c) Are the telescopic stages 2a, 2b in the direction Y opposite the representations according to the Fig. 4 a) and Fig. 4 b) shown retracted onto the frame 3 of the load-handling device 1, so that the load-handling device 1 can be easily moved horizontally and / or vertically together with the containers 4-1 and 4-2 in this configuration.
