Description

[0001] Floor support for a block storage system

[0002] Technical area

[0003] The invention relates to a floor mount according to the preamble of claim 1.

[0004] State of the art

[0005] There are no known warehouse floor leveling elements for block high-bay warehouses from the state of the art.

[0006] In block storage systems with top-loading, transport boxes, for example, measuring approximately 650 x 450 x 450 mm, are loaded into and unloaded from above via robotic trolleys that move along rails on the scaffolding system. With this loading method, the entire storage scaffold must be constructed with water tank precision, as the transport boxes are guided vertically across the storage scaffold or scaffold shaft during loading and unloading by the trolleys.

[0007] Object of the invention

[0008] The object of the invention is to invent a functionally reliable compensation element for a self-sufficient block storage system without the dependence on a flat warehouse floor.

[0009] In addition, the cost-intensive renovation of warehouse floors and, in the case of a new building, the additional high costs for a 100% flat warehouse floor are to be saved.

[0010] In order for the transport box in the block storage scaffold to stand on the warehouse floor at a 90° angle to the block storage scaffold and block storage shaft, a plastic floor leveling element should be developed for each box shaft in the scaffold and designed for a load capacity of approx. 1500 kg, which means that a maximum of 30 boxes with a load capacity of approx. 50 kg should be stacked in the block storage shaft.

[0011] Solution to the task

[0012] The features of claim 1 lead to the solution of the problem.

[0013] Advantageous embodiments are described in the subclaims.

[0014] A floor support according to the invention is intended for use in a high-bay warehouse with a subfloor. These subfloors often exhibit unevenness or are, even slightly, sloping. Making these uneven or sloping surfaces suitable for a high-bay warehouse requires extensive sanding work, which is very complex and expensive in particularly large warehouses with large square footage. The floor support is intended to compensate for the unevenness and any sloping floor of the warehouse and position the boxes at a 90° angle to the warehouse management system.

[0015] The floor support according to the invention is used in such a way that it is installed on the subfloor in a block storage shaft of a high-bay warehouse. It essentially serves as a floor leveling element for each storage shaft in the high-bay warehouse. To achieve this, the user must provide a floor support for each block storage shaft to make the high-bay warehouse system independent of the warehouse floor.

[0016] The idea is that a floor support can be inserted into each box storage shaft between the warehouse floor and the stacked transport boxes in the block storage shaft before the box shaft is loaded.

[0017] To ensure that the first stacked transport box is centered in the floor support, the floor support is divided into two areas.

[0018] The transport box receiving area features a cable pull pocket on one of its inner walls. The upper area, located away from the ground when installed, has a surrounding box receiving frame area consisting of a conical centering edge with grip pockets for the trolley cable pull.

[0019] According to the invention, a transport box receiving area, when installed, has a force accumulator on the side facing the ground. This force accumulator has the property of absorbing the force exerted, for example, by the transport boxes' weight and compensating for it in a defined manner so that the transport box lies flat in the ground support. This also applies if the ground is uneven, for example. The installed state is achieved when the spring base rests on the ground and the transport box receiving area is positioned away from the ground. The lower frame area is therefore equipped with movable deformation elements all around.

[0020] For this purpose, the energy storage device is arranged between a spring base and the transport box receiving area.

[0021] The transport box support area accommodates the transport box. The spring base has a flat surface that rests flush with the ground. The lower, thin, at least circumferential spring base absorbs any unevenness in the hall floor, allowing the energy storage devices to adapt to the ground and the box load, aligning the base support with the stacked transport box in the block storage shaft and scaffolding at a 90° angle to the guide scaffolding.

[0022] A preferred design for the energy storage device is a flat spring. A flat spring is a strip of material that is longer than it is wide, with a wave-like shape arranged lengthwise. It is also possible for several flat springs to be arranged in a strip spring block. The division of the strip spring blocks along the perimeter of the floor support means that several strip flat springs are arranged side by side to form a block. In the lower spring base, between the surrounding lower movable frame surface and the upper frame area, they compensate for the uneven or sloping hall floor with a flexible geometry and secure the floor support to the block storage shaft, determining the load.

[0023] The strip spring block consists of flat springs arranged side by side, mirroring each other. The individual flat springs are arranged in a mirror image to support each other against buckling.

[0024] Additionally, a gap can be provided between two strip spring blocks. This gap is an area located between the transport box support area and the spring floor. This increases flexibility in the event of even minor disturbances in the surface area of ​​the subfloor. A spring joint can also be present in the gap area. The spring joint also increases the ability of the floor support to adapt better to the subfloor. To allow the thin, circumferential spring floor to adapt even more flexibly to the hall floor, another design features multiple interruptions in the circumferential spring floor with a spring geometry.

[0025] In a preferred embodiment, the flat spring has a stylized fir tree crown shape in longitudinal section, i.e. from the transport box receiving area to the spring base, wherein a first area has a thin wall thickness, a middle area has a medium wall thickness and the base area has a thick wall thickness. The middle area is arranged between the first area and the base area. By arranging different wall thicknesses in different areas of the flat spring, optimal weight absorption is possible. In order to compensate for the stacked load of 50 - 1500 kg across the uneven or sloping warehouse floor surface and to support the stacked load in the frame, the spring band thickness of the support bands is designed with different thicknesses, i.e. from the base side towards the upper frame area, the spring band continuously becomes thicker in cross-section.

[0026] Additionally, corner reinforcement can be provided, for example, between the thick and medium wall thicknesses. To prevent stress fractures, the corner areas of the support belts are designed to be slightly thicker than the parallel flat areas. The belt spring blocks are arranged on the surrounding floor support surface, which has direct contact with the hall floor.

[0027] The transport box receiving area has a retainer on one of its outer walls. The retainer is spring-loaded and, by engaging with corresponding receptacles in the block storage shaft of a high-bay warehouse, prevents one of the transport boxes from becoming jammed in the transport box receiving area and dragging the floor support with it. To prevent, resolve, or counteract any self-locking or jamming in the conical centering area between the frame and the transport box, the floor support has several retainers on the outer wall in the upper frame area to anchor itself to the guide frame.

[0028] In one embodiment, the base support is designed as a frame, with the transport box support area also being adapted to the frame in terms of shape and dimensions. The same applies in this case to the spring base and the energy storage devices arranged between the spring base and the transport box support area, for example, in the form of flat springs.

[0029] The frame can also feature a surrounding frame structure with stability ribs. To increase the stability of the floor support, another design incorporates additional stability ribs between the surrounding frame structure in the upper frame area.

[0030] In another embodiment, the frame can have reinforcing ribs connecting longitudinal and / or transverse walls. The entire floor support wall surface is provided with stability ribs all around in the outer upper area, i.e., facing away from the substructure when installed, to counteract deformation and deformation under load.

[0031] Character description

[0032] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings.

[0033] Examples of implementation

[0034] Figure 1 shows a 3D view of a base support 1 according to the invention with the upper transport box support area 2 and the lower movable spring base 3, wherein various energy accumulators 7 in the form of flat springs 21 are arranged between the spring base 3 and the transport box support area 2. Several flat springs 21 are combined to form individual strip spring blocks 4. One of the flat springs 21 is always considered to be two related, adjacent strands, although the second flat spring next to the first flat spring shares a common strand.

[0035] Band spring block 4 means that several flat springs 21 are arranged next to one another between the rotating movable spring base 3 and the transport box receiving area 2 to form a flexible spring block.

[0036] The arrangement of the strip spring blocks 4 with the individual flat springs 21 adapts to the uneven or sloping surface with the load bearing, determining load compensation.

[0037] The transport box receiving area 2 has a gripping cable pull pocket 6 on an inner wall 22. Using the gripping cable pull pockets 6 in the upper transport receiving area 2, i.e., facing away from the ground, the floor support 1 is inserted into the block storage shaft 20 or pulled out of the block storage shaft 20.

[0038] The stability ribs 8 arranged all around an outer wall 23 of the floor support 1 give the system the necessary stability against warping and deformation in order to guarantee the required load-bearing capacity of 50-1500 kg.

[0039] As shown enlarged in Figure 7, the strip spring block 4 in this embodiment consists of flat springs 21 arranged in a mirror image of one another. In this case, the flat spring 21 has a stylized fir tree crown shape in longitudinal section, i.e. from the transport box receiving area 2 to the spring base 3, and next to it an upside-down, mirror-inverted fir tree crown shape. The two adjacent flat springs 21 share a common strand. Three adjacent flat springs 21 in turn consist of three strands, with a first region having a thin wall thickness 14, a second region having a thick wall thickness 15, and the base region having a thick wall thickness 16. In this case, a corner reinforcement 17 is provided in the transition between the thick wall thickness 16 and the middle wall thickness 15.

[0040] Due to the continuously increasing wall thickness with the corner reinforcement 17 of the individual flat springs 21, the unevenness of the hall floor can be compensated for by the varying load on the floor support 1, so that the floor support 1 with the attached transport box 9 at a 90° angle to the guide frame of the block high-bay warehouse readjusts itself depending on the load. Figure 2 shows a side view of the long frame side of the floor support 1 with the stabilizing ribs 8 on the outer wall 23 of the upper frame section 2.

[0041] The strip spring blocks 4 with the individual flat springs 21 are arranged in the spring base 3 and are limited by the movable circumferential spring base 3.

[0042] Figure 3 shows a side view of the long frame side of the floor support 1 as a further embodiment with a spring base 3 interrupted by several spring joints 10 to increase mobility and adaptability to uneven or sloping surfaces. The spring joints 10 are arranged in the area of ​​the free spaces 5 between the strip spring blocks 4.

[0043] Figure 4 is a side view of the short frame side of the floor support 1 with the stabilizing ribs 8 on the outer wall 23 of the upper floor support area 2.

[0044] The strip spring blocks 4 with the individual flat springs 21 are arranged in the spring base 3 and are limited by the movable circumferential spring base 3.

[0045] Figure 4 also shows a retainer 11, which is arranged on the outer wall 23 of the floor support 1 and anchored to the guide frame of the block high-bay warehouse in order to prevent, release, or counteract any possible self-locking or tilting in the conical centering area between the stored transport box 9 and the floor support 1 in the transport box support area 2. Figure 5 shows a plan view of the floor support 1 with the gripping cable pockets 6. The surrounding frame structure 12 with the stability ribs 8 (not visible here) receives the transport box 9 in the upper area 2 and centers it in the block storage shaft. The protruding retainers 11 can also be seen on the longitudinal edges.

[0046] Figure 6 shows a plan view of another embodiment of the floor support 1. This embodiment 2 features additional reinforcing ribs 13 to provide the frame structure with increased stability against warping and deformation under maximum load. In this embodiment, connecting reinforcing ribs 13 are provided on the longitudinal walls.

[0047] Figure 7 is a partial side view of the soil receptacle 1 according to the invention with the retainer 11 in order to fix the soil receptacle 1 in the desired position in the block storage shaft.

[0048] The flat springs 21 are arranged between the spring base 3 and the upper transport box receiving area 2, the flat springs 21 are also arranged as band spring blocks 4, consisting of several flat springs 21, wherein each flat spring 21 is supported by the opposite flat spring 21 against buckling in that the springs are arranged in a mirror image to each other.

[0049] The continuous increase in wall thickness in the flat spring area 21 from bottom to top, i.e., from a thin wall thickness 14 through a medium wall thickness 15 to the thick wall thickness 16 and with the corner reinforcement 17, achieves a force and load distribution in the spring system, ensuring the varying load capacity of 50-1500 kg, and preventing stress fractures due to the corner reinforcement 17. Figure 8 shows a partial side view of the floor support 1 according to the invention with a strip spring block 4, constructed with the flat springs 21.

[0050] This circumferential arrangement of the band spring blocks 4 on the circumference of the floor support 1 guarantees high flexibility and mobility with optimal load absorption and compensates for the most diverse unevenness of the hall floor and any possible slopes of the subsurface.

[0051] Figure 9 shows a situation view of the floor support 1 in the block storage shaft 20 of the block high-bay warehouse with a sloping subsurface 18 and consequently also a floor support 1 sitting slantedly in the block storage shaft 20 without load via a loaded transport box 9.

[0052] Figure 10 shows a situation view of the floor support 1 in the block storage shaft 20 of the block high-bay warehouse with a sloping base 18, loaded with an equipped transport box 9.

[0053] The band spring block system 4, which balances the floor support 1 with the loaded transport box 9 in the scaffolding and shaft system of the block storage, and thus enables the gripping cable pull system of the trolleys to move the transport boxes 9 without jamming in the block storage shaft 20.

[0054] Figure 11 shows a situational view of the floor support 1 in the block storage shaft 20 of the block high-bay warehouse with an uneven surface 19 as a design with an interrupted spring floor 3 through several spring joints 10. The floor support 1 rests on the uneven edges and peaks of the surface without being loaded by the transport boxes 9, without having to adapt to the surface or compensate for it. Figure 12 shows a situational view of another design of the floor support 1 in the block storage shaft 20 of the block high-bay warehouse with an uneven surface 19, loaded with stacked, filled transport boxes 9. The strip spring block system 4 balances the floor support 1 with the filled transport boxes 9 via the interrupted spring floor 3 through several spring joints 10.

[0055] The floor support circumference is divided into individual band spring block elements via several spring joints 10 so that the transport box 9 adjusts to the block storage shaft at a 90° angle to the block storage shaft 20 in the block storage system.
