Description

The invention relates to a shelf storage system according to the preamble of claim 1.

Such shelf storage systems have at least two essentially vertically extending cheeks and at least two essentially horizontally extending cross beams. The cross beams are arranged essentially at the same height as the shelf storage system and connect the cheeks to one another, so that a stable frame construction can be produced. The cheeks can, for example, each be made from two vertically extending supports that are connected to one another with cross braces. At least one essentially horizontally extending floor element can be arranged between the cross beams, for example by hanging it in the cross beams. This creates a storage area on the top of the floor elements, on which the stored goods can be stored.

In the known rack storage systems of this type, the cross beams are made of tubular profiles with a closed cross section. Disadvantageous

The problem is that the cross members can only be attached to the cheeks using complex measures due to their closed cross section. For example, there are known solutions in which the cross members are cut out in the connection area with the cheeks so that a rivet or screw connection can be made between the cheek and the cross member.

The object of the present invention is to propose a shelf storage system that is easy to manufacture while maintaining high mechanical strength.

This problem is solved by a rack storage system with the features of claim 1.

Advantageous embodiments of the invention are the subject of the subclaims.

According to the invention, the cross members are made from a longitudinal profile with an open cross-section. This means that the inside of the cross member profile is also freely accessible, so that, for example, holes can be easily made to accommodate a rivet or screw connection. When mounting the cross members on the cheeks, the screws and rivets can then be pushed through the recesses from the inside of the cross member profile and secured.

It is advantageous if the open side of the cross member faces an outside of the rack storage, so that the cross members can be attached in a simple manner, for example by riveting or screwing from the open profile side.

When designing the cross beams and/or floor elements, care should be taken to ensure that the outer edges of these components are rounded, at least in the areas with which the stored goods can come into contact during storage and/or retrieval. Otherwise, if the cross beams and/or floor elements are designed with sharp edges, there is a risk that the stored goods will be damaged by the relative movement along these

sharp edges. This danger is particularly present when cartons are to be stored in the rack warehouse as goods. If these cartons are not lifted high enough by the automatic handling devices, for example during automatic storage or retrieval, the underside of the cartons can easily be damaged by sharp edges, for example by being torn open by an interfering edge.

According to a preferred embodiment of the invention, the cross members may have a substantially C-shaped cross section.

Such supports have an upper and a lower leg pointing towards the open side of the profile, which are connected to one another on one side of the profile by a connecting web. To produce the shelf storage, such profiles can be attached to the cheeks in such a way that the open side of the profile points towards the outside of the shelf storage. The profile then comes into contact with the cheeks with the connecting web between the upper and lower webs and can be easily installed in this position.

It is advantageous if at least the upper leg of the C-shaped profile is bent on the open side of the profile to form an edge. By pulling the component wall around in the area of the upper leg on the open side of the profile, a rounded body edge is created so that the stored goods are not damaged by contact with this edge during storage or retrieval.

The risk of damage to the stored goods can be further reduced if the top of the cross member has a run-on surface for the stored goods that extends along the cross member. This run-on surface extends diagonally upwards at a certain angle from the upper edge of the cross member facing the outside of the rack storage. If the stored goods are not

raised high enough so that the stored goods come into contact with the crossbeam, the run-up surface can be used to ensure that the lower edge of the stored goods is slowly raised on the run-up surface in the manner of an inclined plane. In these cases, tearing of the lower edge of the stored goods can thus be largely prevented.

The angle at which the run-up surface extends diagonally upwards should preferably be selected from a range of approximately 5° to 35°. This angle of inclination and the length of the inclined plane formed by the run-up surface must be adjusted to the maximum tolerable height offset of the stored goods during the storage movement.

To adjust the floor elements on the crossbeams, the crossbeams can have recesses, in particular slots, in which essentially vertically running wall sections of the floor elements can be brought into engagement. The width of the slots can in particular correspond exactly to the material thickness of the floor elements in the area of the vertically running wall sections.

Another way to reduce the risk of damage to the stored goods during storage or retrieval is to attach the floor elements to the crossbeams in such a way that the top of the floor elements extends essentially in the plane defined by the top of the crossbeam. This can be done, for example, by cutting out the recesses in the crossbeams for hanging the floor elements so wide that the floor elements slide down so far after being hung in the recesses that the top of the crossbeam and the top of the floor element are at the same height.

According to a preferred embodiment, the upper side of the cross member has a bead whose height is greater than or equal to the height of the front edge of the floor element. This ensures that the front

edge in the area of the bead is taken up by the cross member and thus covered.

Another way to reduce damage to the stored goods during storage and retrieval can be achieved if the wall of the floor element, which forms the top of the floor element, extends so far outwards and downwards at the end facing the outside of the shelving system that the upper edge of the cross member facing the outside of the shelving system can be at least partially encompassed by the wall. As a result, the stored goods on the floor element only come into contact with the top and, in addition, disruptive edges at the transition between the floor element and the cross member are covered at the top by the wall of the floor element.

Depending on the mass of the goods stored, weight forces are transferred from the floor elements to the cross beams and from there to the sides of the storage rack. Since the cross beams are attached to the sides, they are bent downwards by this weight load in the manner of a rod firmly clamped on both sides. When using profiles with an open cross section to produce the cross beams, this downward deflection of the cross beams immediately results in torsion of the cross beams. This torsion of the cross beam is zero at the clamping points in the area of the sides and reaches its maximum value in the area of the middle between the clamping points. The torsion of the cross beams is undesirable because it can cause smooth-surfaced body edges to shift against each other, so that there is a risk of damage to the goods stored during storage or removal. The torsion of the cross beams can be greatly reduced if at least one of the floor elements arranged between two sides is positively and/or force-fittedly connected to the cross beam. This additional connection of the cross beam with a

An additional clamping point is created in the floor element, which provides additional stiffening for the cross member.

Since the torsion of the cross member is greatest in the middle between two clamping points, it is particularly advantageous if the cross member is divided between two cheeks into sections of as equal length as possible by the floor elements that are positively and/or force-fittedly connected to the cross member. This creates sections with as even a torsion profile as possible, whereby the maximum torsion values that occur are significantly lower due to the shorter free length.

The connection between the cross member and the floor element can be achieved, for example, by screwing or riveting the floor element to the cross member after it has been hooked into the cross member. Of course, all other types of connection techniques, such as welding or gluing, are also conceivable.

If the shelving system is designed as a steel construction, for example, it is particularly advantageous to connect the floor elements to the cross beams using rivets.

Depending on the requirements of the storage task to be solved, the floor elements can form a substantially closed floor surface on the top of which the stored goods can be placed, or they can extend parallel to one another with a certain lateral distance from one another. If a sprinkler system is to be used in the shelving system to prevent fires, the floor elements are advantageously arranged with a lateral distance from one another so that the water released from the sprinkler system from above can flow through the shelving elements of the shelving system arranged one above the other. In addition, in an advantageous embodiment, the floor elements can have recesses that ensure a certain air and/or water permeability of the floor elements.

According to a preferred embodiment of the invention, at least one stop element is arranged on the top of the floor element, which extends upwards over the top of the floor element and can come into contact with the back of the stored goods. This stop element can be used to limit the maximum insertion depth of the stored goods during the storage movement. This makes it possible, for example, to push the stored goods into the shelf storage until the applied feed force increases abruptly due to the contact of the stored goods with the stop element. In addition, it can be achieved that two pieces of stored goods can be placed on each floor element, each of which is stored in the shelf storage from the opposite outer sides of the shelf storage, since the insertion depth can be limited from both sides by a stop element.

In order to achieve a clean alignment of the stored goods and, in extreme cases, to prevent the stored goods from falling down during storage or retrieval, at least one guide element can be arranged on the top of the floor element, extending upwards over the top of the floor element, on which a side surface of the stored goods can be guided at least in parts during the storage and/or retrieval movement. For this purpose, the floor element can be bent upwards a little along the side edges, for example, so that lateral guide strips are created.

It is particularly advantageous if the floor elements are designed to be essentially mirror-symmetrical with respect to two vertically extending center planes arranged perpendicular to one another. This ensures that the floor elements can be arranged between the cross members regardless of direction.

In principle, any manufacturing technique is possible for the production of the floor elements. Particularly inexpensive and stable floors

The elements can be manufactured if the floor elements are designed in the form of bent sheet metal parts. For example, a blank is first cut or punched out of a sheet of sufficient thickness and then bent into a three-dimensional floor element with correspondingly increased rigidity.

By combining several parallel panels connected by cross beams, shelf walls of basically any width can be produced.

By arranging several cross beams on the rack storage system one above the other, rack storage systems of basically any height can be manufactured.

Fig. 1 shows a section of a shelving system 1. The shelving system 1 essentially consists of vertically extending cheeks 2 and 3, cross beams 4 attached to the cheeks 2 and 3 and floor elements 5 arranged on the cross beams 4. The open cross section of the longitudinal profiles used to produce the cross beams 4 can be seen. The cheeks 2 and 3 are each essentially made of two support profiles 6 and 7 and cross bracing profiles 8 and 9 arranged between them. A piece of the stored goods, for example the boxes 10 and 11 of different sizes, can be placed on two floor elements 5 each, which are arranged parallel to one another and laterally spaced apart. It should be noted that the shelving system 1 is only shown in a section in Fig. 1 and can basically continue to the right and left or up and down in any length.

Fig. 2 shows the shelf storage 1 in a side view. The supports 6 and 7, the cross braces 8 and 9, the cross beams 4 and the floor elements 5 suspended in the cross beams 4 can be seen. The boxes 10 and 11 can be pushed into the compartments formed by the floor elements 5 from the outer sides 12 and 13 of the shelf storage 1. In this case, two stop elements 14 and 15 are provided in the middle of the floor elements 5, which limit the insertion movement towards the rear when storing the boxes 10 and 11.

Fig. 3 shows the rack storage 1 from the outside 12 in front view. The floor elements 5 are connected to the part of the wall 22 which

The wall 22 surrounds the upper side of the floor element 5a and 5b, which forms the top side of the floor element and extends so far outwards and downwards at the end facing the outside 12 of the shelf storage 1 that the upper edge 14 of the cross members 4 facing the outside 12 of the shelf storage 1 is enclosed by the wall 22. The floor elements 5a and 5b, which are each arranged closest to the middle of the area between the cheeks 2 and 3, are each firmly connected to the cross members 4 with a rivet 16. As a result, the free length with which the cross members 4 can be twisted between the cheeks 2 and 3 is more or less halved, so that the maximum torsion occurring on the cross members 4 is greatly reduced.

Fig. 4 shows the rack storage 1 with the cross beams 4, the supports 6 and 7, the cross braces 8 of the cheeks 2 and 3 and the floor elements 5 on which the boxes 11 are stored in a view from above.

Fig. 5 shows detail A from Fig. 2 and shows the connection of the floor element 5 to the cross member 4 on an enlarged scale. The cross member 4 is made from a longitudinal profile that is open in cross section, with the open side 24 of the cross member 4 facing the outside 13 of the shelf storage 1. The upper edge 14 of the cross member 4 facing the outside 13 and the complementary shaped edge 17 of the floor element 5 are rounded so that cartons that come into contact with the edges 14 and 17 during the storage or retrieval movement are not damaged. The rounding of the edge 14 is achieved in that the cross member 4, which is essentially C-shaped in cross section, has an upper leg 18 that is bent downwards on the open side 24 of the cross member 4. The upper edge 19 of the cross member 4, which faces the interior of the shelf storage 1 and is shown in Fig. 5 as being hidden by the floor element 5, has recesses 20 in the form of slots into which the floor element 5 can be hung with a vertically extending wall section 21. The wall 22 of the floor element 5, which forms the upper side of the floor element 5, extends at the end 23 facing the outside 13 of the shelf storage 1 so

far outwards and downwards so that the edge 14 of the cross member is encompassed. The rivet 16 firmly connects the cross member 4 and the floor element 5 to one another, so that torsion of the cross member 4 in the area of the rivet 16 is largely excluded.

Fig. 6 shows a second embodiment of a connection between a base element 25 and a cross member 26. The upper leg 27 of the cross member 26 is bent downwards at the free end, so that a rounded edge 28 is formed. In addition, the upper leg 27 has a bead 30 behind the recess 29, which extends along the cross member 26, so that as a result, after the base element 25 has been hung in the cross member 26, the upper side 31 of the base element 25 runs in the plane defined by the upper side 32 of the cross member 26. When storing and retrieving the boxes, the boxes can therefore be moved at a uniform level, which is determined by the upper sides 31 and 32.

Fig. 7 shows the connection of the cross member 4 with the base element 5 and a cardboard box 11 placed on it in an enlarged, perspective section. The rivet 16, the edge 14 and the wall 22 of the base element drawn around the edge 14 can be seen.

Fig. 8 shows the connection according to Fig. 7 from the rear side of the cross member 4. One can see the support 6 and the edge of a recess 20 in the cross member 4, into which the floor element 5 is suspended.

Fig. 9 shows the floor element 5 in a side view, whereby the floor element 5 is shown in a shortened form and can be extended as desired in the sections 33, 34 and 35 (not shown). The vertical wall sections 21 can be seen, with which the floor element 5 can be suspended in the cross members 4, and the stop elements 14 and 15. The two ends 23 of the wall 22, which forms the top of the floor element 5, are bent downwards.

and have recesses 38 through which a rivet connectable to the cross members can be pushed.

Fig. 10 shows the base element 5 with the side surfaces 39 and 40 and the downwardly drawn end 23 of the wall 22.

Fig. 11 shows the contour of a blank for a bent sheet metal part, as can be used to produce a floor element 5. It can be seen that in addition to the stop elements 14 and 15, a third stop element 41 is provided, which can be bent upwards as an alternative to the stop elements 14 and 15. If the stop element 41 is bent upwards, the stop elements 14 and 15 remain unused, so that as a result the stored goods can only be stored from one outside of the shelf storage. The length of the stored goods can be correspondingly greater.

Fig. 12 shows the connection of two cross beams 53 with a floor element 42 shown in abbreviated form. The function of the floor element 42 and the floor beams 53 essentially corresponds to the function of the floor elements 5 and cross beams 4 shown so far. In addition, the cross beams 53 each have a run-on surface 43 which extends diagonally upwards from the edge 44 at an angle α. In addition, a guide element 45 is provided on one side of the floor element 42, on which the stored goods can be guided and aligned laterally during the storage and/or retrieval movement. The guide element 45 can be produced by bending up one side surface 46.
