Description

[0001] Rack storage

[0002] DESCRIPTION:

[0003] The invention relates to a rack warehouse with at least one compartment support which delimits a storage aisle and / or a storage compartment on one side, and with a sprinkler system having at least one supply pipe, from whose supply pipe a sprinkler pipe having at least one sprinkler head extends into the storage aisle and / or the storage compartment, wherein a deflection element is arranged on the underside of the compartment support which extends further in the direction of a floor of the storage aisle than the sprinkler head.

[0004] Rack warehouses, especially high-bay warehouses, are an important element in merchandise management and logistics. Such rack warehouses typically consist of numerous compartment supports on which goods are stored or retrieved. Pallets can be placed directly on the compartment supports or floor plates can be arranged to hold the goods. The goods are guided along the compartment supports during both storage and retrieval, often reaching the shelves to ensure optimal use of storage capacity. It should be noted that multiple storage levels can be arranged one above the other to increase storage capacity.

[0005] Such high-bay warehouses contain valuable assets that must be protected, particularly against fire hazards. For this reason, high-bay warehouses are equipped with sprinkler systems that distribute extinguishing agents, usually water, supplied by sprinklers with a sprinkler head and a deflector plate in a piping system. These sprinklers are located in the storage aisles and can also be assigned to the storage compartments. The sprinkler heads extend downwards from the sprinkler pipes of the piping system into the open space. These sprinkler heads are therefore exposed and at risk of damage when stored goods are being loaded or unloaded, for example if the goods or a storage and retrieval machine collides with them. Even a bending of the deflector plate can result in the extinguishing agent no longer being distributed evenly, preventing hot spots or embers from being reached.

[0006] To improve this situation, WO 2015 / 059143 A1 discloses a sprinkler guard consisting of a mounting section, for example, pipe clamps, and a protective section that can be fixed to the sprinkler pipes by means of the mounting section. The protective section comprises, in particular, protective brackets surrounding the sprinkler head, which prevent direct contact with the sprinkler under a given force.

[0007] However, it should be noted that the protective section should not impair the distribution of the extinguishing agent as much as possible and therefore the extension and dimensions are also limited with regard to the material thickness.

[0008] It is therefore the object of the present invention to design a shelf storage system that improves the protection of the sprinkler head against damage.

[0009] This object is achieved by a rack storage system having the features of claim 1. Advantageous embodiments with expedient further developments of the invention are specified in the dependent claims.

[0010] The shelf storage system according to the invention is characterized in that protection of the sprinkler head can be improved by limiting the height of the upper edge of the goods when maneuvering the goods during storage or retrieval. If the permissible height is exceeded due to goods being stored too high on a pallet, for example, contact is avoided by deflecting the contact partner. The deflector element deflects the contact partner downwards towards the floor in a form-fitting manner like a control curve. It should be noted that a high material thickness is certainly possible for the deflector element, since its assignment to the compartment support avoids space restrictions and dissipation of the acting force is ensured. Shielding of the extinguishing agent is also largely avoided because there is a large distance to the sprinkler head and only a small solid angle adjacent to the compartment support is affected.

[0011] It is particularly advantageous that the protective effect is complementary, and it is also possible for the sprinkler head to be assigned a protective device with at least one protective bracket surrounding the sprinkler head, which is attached to the sprinkler pipe, and for the deflection element to extend further toward the floor of the storage aisle than the protective bracket. It has proven effective for the protective device to have two protective brackets arranged on either side of the sprinkler head, each with a thread at its free end, through which the protective brackets are attached to the sprinkler pipe by means of pipe clamps.

[0012] The protective effect is particularly effective when the deflection element is positioned on the fan support to the side of the sprinkler head, so that the projection of the sprinkler head or the protective device and the deflection element coincide. It is also conceivable that the deflection element is positioned in front of the sprinkler head in the direction of movement of the contact partner, forcing an early deflection; however, this would require subsequent height adjustment or a significant extension.

[0013] It is preferred if the deflection element is formed as a wedge that thickens from the entrance of the storage aisle and / or storage compartment toward the sprinkler head until the wedge projects beyond the sprinkler head or the protective device toward the floor. Compared to a simple stop, the wedge offers the advantage that there is no abrupt stop with a large impact on the goods and / or the storage and retrieval machine. Instead, an increased resistance gradually builds up for the operator, which can also trigger a reaction from the operator to correct the height.

[0014] In practice, it is advisable for the shelf support to be designed as a T-beam with a crosspiece pointing towards the floor, to whose free ends the wedge is attached. The T-beam can, in particular, be designed as a double T-beam to optimize load-bearing capacity for the goods stored above. However, the use of the crosspiece positioned below is sufficient, providing free areas for attachment, especially if the wedge is formed by two wedge brackets attached to the edges of the shelf support.

[0015] It is also possible to provide two bracket plates with passages for attaching the wedge brackets to the compartment support and with passages for the wedge brackets.

[0016] Alternatively, the wedge may be formed as a plate, at the end of which, associated with the sprinkler head, a web protrudes which determines the thickness of the wedge.

[0017] The width of the panel can exceed the width of the compartment support, and cross braces whose width exceeds the width of the compartment support can also be arranged at the free ends of the panel. This creates free space on the panel or cross braces where fastening devices can be installed.

[0018] According to a further alternative, the wedge is formed from two wedge halves, which have a groove on their mutually facing sides for attachment to the crosspiece. This embodiment utilizes the design of the T-beam for easy attachment and provides maximized material strength. It is further provided that the wedge has a flattened portion in the area of ​​the sprinkler head or the protective device, thus eliminating the need for a further rise of the wedge over the extension of the sprinkler head.

[0019] It is preferred if the compartment carrier storage compartments are provided several times to form a plurality of storage aisles and / or storage compartments, into each of which a supply pipe with at least one sprinkler head protrudes, since in this way the capacity of the shelf storage can be adapted as required.

[0020] If the wedge is formed as a double wedge in the direction of the storage aisle, then protection is provided not only in one direction of movement of the goods.

[0021] The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figure, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments are also considered to be encompassed and disclosed by the invention that are not explicitly shown or explained in the figure, but which emerge and can be produced through separate feature combinations from the explained embodiments.

[0022] Further advantages, features, and details of the invention will become apparent from the claims, the following description of preferred embodiments, and the drawings. Herein:

[0029] Figure 8 is a perspective view of the two wedge halves on the

[0030] Crossbar of the T-beam,

[0031] Figure 9 shows a representation corresponding to Figure 3 with a wedge formed from two wedge brackets,

[0032] Figure 10 is a perspective view of the two wedge brackets on the crossbar of the T-beam,

[0033] Figure 11 is a plan view of a bracket plate for fastening one end of the wedge brackets, and

[0034] Figure 12 is a plan view of another bracket plate for attaching the other end of the wedge brackets. Figure 1 shows the parts of a rack storage system 1 required to explain the invention. Shown is a rack storage system 1 with at least one compartment support 2, which can in particular be designed as a cantilever arm; wherein in the embodiment shown, three compartment supports 2 are present. To increase storage capacity, the number of compartment supports 2 can be increased, both in the storage level shown and in further storage levels at a different height. The compartment supports 2 can also define a storage aisle at the edge of the rack storage system, through which goods are transported for storage and retrieval. According to the embodiment shown, the compartment supports 2 define a storage compartment 3 in which the goods can be stored, in particular on pallets.

[0035] The rack storage 1 has a sprinkler system 4 with a supply pipe 5, from which a sprinkler pipe 7 having at least one sprinkler head 6 extends into the storage aisle and / or the storage compartment 3.

[0036] On the underside of the compartment support 2, a deflection element 8 is arranged, which extends further in the direction of a floor of the storage compartment 3 than the sprinkler head 6 (Figure 2) or a protective device 9 assigned to the sprinkler 6. In the embodiment shown, this protective device 9 comprises two protective brackets 10 surrounding the sprinkler head 6, which are fastened to the sprinkler pipe 7 by a thread formed at their free ends, through which the protective brackets 10 can be fastened to the sprinkler pipe 7 by means of pipe clamps 11.

[0037] Figure 1 shows that the deflection element 8 is arranged on the fan support 2 laterally of the sprinkler head 6, in such a way that the linear projection of the sprinkler head 6 or the protective device 9 and the deflection element 8 coincide; this fact is also evident from Figure 2.

[0038] In the illustrated embodiments, the deflection element 8 is formed as a wedge 12 that thickens from the entrance of the storage aisle and / or the storage compartment 3 toward the sprinkler head 6 until the wedge 12 projects beyond the sprinkler head 6 or the protective device 9 toward the floor. The compartment support 2 is formed as a T-beam with a transverse web 13 facing the floor, to whose free ends the wedge 12 is attached.

[0039] Figures 1, 2 as well as 9 and 10 show that the wedge 12 is formed by two wedge brackets 14 which are fastened to the edge of the compartment support 2, for which purpose two bracket plates 15, 16 are provided with passages for fastening the wedge brackets 14 to the compartment support 2 and with passages for the wedge brackets 14, which are shown in isolation in Figures 11 and 12. The first bracket plate 15 has two holes for fastening screws as passages and two holes for the wedge brackets 14, while in the second bracket plate 16 the holes for the wedge brackets 14 are widened to form elongated holes 23 reaching up to the edge, so that the ends of the wedge brackets 14 can be received therein, even if the wedge 12 runs close to the compartment support 2.

[0040] Figures 3 to 5 show that the wedge 12 is formed as a plate 17, at the end of which, associated with the sprinkler head 6, a web 18 protrudes, determining the thickness of the wedge 12 (Figure 3), while the width of the plate 17 exceeds the width of the fan support 2, or cross struts 19 are arranged at the free ends of the plate, the width of which exceeds the width of the fan support 2 (Figure 4). This projection can be used for fastening purposes, allowing the fastening screws to be guided laterally past the fan support 2.

[0041] A further embodiment is shown in Figures 6 to 8, in which the wedge 12 is formed from two wedge halves 20 which have a groove 21 on their mutually facing sides for fastening to the crosspiece 13.

[0042] All embodiments shown have in common that the wedge 12 has a flattened portion 22 in the area of ​​the sprinkler head 6 or the protective device 9, thus eliminating the need to further increase the wedge height once the required height has been reached in the area of ​​the sprinkler head 6. According to an embodiment not shown, the wedge 12 can be formed as a double wedge in the direction of the extension of the storage aisle 3 and / or the storage compartment 3, this embodiment being particularly suitable for use in a storage aisle.
