Description

Integration of container maintenance The present invention relates to a high-bay warehouse for the storage and unloading of exchange boxes, preferably containers, the high-bay warehouse having a large number of storage locations for exchange boxes, preferably containers, arranged horizontally side by side and vertically stacked, and warehouse aisles arranged between each group of storage locations and extending parallel to each other, each of the warehouse aisles having at least one shelf access device that can move back and forth, and the shelf access device is configured and designed to move the exchange boxes, preferably containers vertically and horizontally, and to move them into and out of the storage locations. High-bay warehouses (HBS) are well known in the art and are widely used, particularly in transshipment systems at seaports or inland ports, or in landside warehousing and logistics. High-bay warehouses typically have a large number of racking levels, preferably independent racking levels, arranged horizontally side by side or vertically one above the other, and warehouse aisles running parallel to each other between the racking levels. Within the HBS, rack access equipment is typically used to receive containers from transfer points (e.g., trucks or transshipment center trucks, or preferably self-propelled transport vehicles, optionally rail-based) and transport them from these receiving points to the corresponding racking levels. DE 10 2013 010 455 A1 discloses a RBG safety platform for maintenance and service of a rack access system (RBG) in a high-bay warehouse. This rack access system comprises a lower running gear, a mast extending vertically upward from the lower running gear, and an upper running gear arranged at the upper end of the mast, which interacts with the guide rails of the high-bay warehouse. To ensure safe and reliable maintenance and repair work, a safety platform is arranged in the upper end region of the mast. In the operating state, the safety platform completely surrounds the mast and spans at least one aisle in a section between two opposing rack sections. The safety platform, or at least a portion thereof, can be returned to a starting position in which the rack access system can be moved without collision and can be used regularly. WO 2023 / 115090 A1 discloses a racking storage system comprising storage racks and rack aisles and maintenance aisles arranged therebetween. The maintenance aisles extend within the rack aisles, and some of the maintenance aisles include walkways arranged within stacked maintenance layers. Pedestrian walkways may be arranged at least in some of the walkways between the maintenance aisles to facilitate ascending and / or descending between the maintenance aisles. Each pedestrian aisle may correspond to an ascending and / or descending device. WO 2015 / 124342 A1 discloses an example of such a high-bay warehouse. In this high-bay warehouse, standard containers are received by rack access equipment at a transfer point within the high-bay warehouse. The equipment then transports them to a pre-determined rack level and stores them in the warehouse. The containers are suspended from above and stored transversely in the corresponding rack level using a telescopic system, with the long sides of the containers parallel to the warehouse aisles. This maximizes the use of space within the rack warehouse, as the width of the warehouse aisles only needs to be slightly larger than the corresponding end sides of the container. If the telescopic system is appropriately designed on the rack access equipment, this special handling and storage method for containers, especially empty containers, also allows for the operation of two adjacent rack levels on each side of each warehouse aisle, for a total of four rack levels ("double-deep"). Each warehouse aisle is usually equipped with a rack access device, which can be used to transfer each container from a determined takeover position to the corresponding rack grid. It can also remove the container from the rack grid and send it to a suitable transfer position so that it can then be received by an external transport vehicle directly or indirectly by connecting a suitable transfer device. The capacity of the corresponding rack storage and retrieval equipment to receive, move and transfer containers again and the number of rack storage and retrieval equipment in the warehouse aisles are decisive factors for the transfer capacity of the high-bay warehouse and are usually determined when designing the high-bay warehouse. Generally speaking, in warehouse logistics, it is not only necessary to receive, temporarily store, and then re-deliver loaded containers at the appropriate time, but also to move empty containers in and out of the warehouse. Loaded containers are advantageously received in stacked, independent racking bays. This allows access to each individual container without having to access the stacked containers one by one from top to bottom. While separate racking bays are generally not required for handling empty containers, they can still be advantageously made available, at least temporarily, as needed. Empty containers must be maintained, optionally repaired, and cleaned regularly, in the event of significant damage, after unloading, and primarily in the event of contamination or soiling of the cargo, before further use. Approximately 60% of all used containers require this process, generally referred to as maintenance, after emptying. Thus, in an HBS that transships 100,000 containers annually, 60,000 containers must be inspected, optionally cleaned, and optionally repaired, or at least processed. Before entering the block warehouse or HBS, or after damage or similar issues are detected, empty containers are typically removed from the HBS, picked up by external transport, and transferred to a designated maintenance area. After maintenance, they are returned to the high-bay warehouse by external transport. This approach has proven inefficient, time-consuming, and costly, particularly due to the high number of inbound and outbound operations for maintenance. In view of the above, the object of the present invention is to provide a high-bay warehouse that overcomes the disadvantages known in the prior art and, in particular, provides an efficient and time-saving solution for quickly maintaining exchange boxes, in particular containers, preferably empty containers, with minimal time expenditure and short transport routes. The solution of the present invention for achieving this object is a high-bay warehouse having the features of claim 1. Advantageous technical solutions of the present invention are particularly described in the dependent claims. According to the invention, the high-bay warehouse described at the outset for loading and unloading exchange boxes, preferably containers, is characterized by at least one maintenance area for exchange boxes, preferably containers, which is accessible by at least one rack access device and provides all-round access to the exchange boxes, preferably containers, placed in the maintenance area. Thus, according to the invention, the maintenance area for exchange boxes, preferably empty containers, is integrated into the high-bay warehouse itself, thereby shortening loading and unloading times when maintenance needs are identified. Furthermore, exchange boxes for maintenance can be transferred directly to the maintenance area by a rack access device located within the high-bay warehouse and, after maintenance, can be stored within the high-bay warehouse or directly transported to a transfer point using an external transport vehicle (e.g., in the form of a truck, a transfer center truck, a self-propelled transport vehicle, a crane, or the like). For the purposes of this invention, maintenance is understood to include any type of inspection in the open and closed state, such as optical or mechanical inspection, or inspection by means of X-rays or ultrasound, painting and coating work, locksmithing, carpentry, cleaning, and / or inspection and, if necessary, repair of electrical components (e.g., refrigeration units in refrigerated containers). For the purposes of this invention, maintenance also includes the fact that, after inspection and, if necessary, repair of components of a refrigerated container, further measures, such as cleaning or repair, are deemed unnecessary. According to the invention, the maintenance area can also be subsequently integrated into any type of high-bay warehouse, requiring only the existing high-bay warehouse area to be rebuilt or redesigned. Preferably, the high-bay warehouse has at least one section for storing empty exchange boxes, preferably empty containers. Preferably, the high-bay warehouse is generally designed to receive empty containers, which are then preferably stacked directly on top of each other without requiring a separate rack finder for each individual exchange box, in particular container, and the maintenance area comprises a single placement location, a pair of placement locations arranged side by side and / or one above the other, a whole row of placement locations for exchange boxes arranged one above the other, and / or a block of placement locations for exchange boxes, in particular containers, arranged one above the other and side by side. Preferably, the exchange boxes, preferably containers, can be placed in the individual storage locations by means of a rack access device. This allows for easy access to each individual exchange box, preferably a loaded container, without having to remove the exchange boxes arranged above this particular exchange box, preferably a loaded container. As mentioned at the beginning of this article, this type of empty container handling and storage is usually unnecessary, so that empty exchange boxes, especially empty containers, can also be stored directly stacked on top of each other in the rack modules provided for them. This combination of two situations maximizes the system's operating performance. This means that the majority of containers can be stacked closely together, while a smaller number of containers can be stored in separate compartments. This is particularly advantageous for handling containers. Preferably, the maintenance area is arranged in the high-bay warehouse in the immediate vicinity of at least one section for storing empty exchange boxes, preferably empty containers. That is, if the high-bay warehouse only has one section for storing empty exchange boxes, preferably empty containers, and is not entirely dedicated to this storage as in a preferred embodiment of the present invention, the immediate vicinity of the maintenance area to the section for storing empty exchange boxes shortens the transport paths within the high-bay warehouse, since the majority of maintenance work is carried out on empty exchange boxes, preferably empty containers, and not on exchange boxes, preferably containers, that are loaded or at least partially loaded. In a preferred embodiment of the present invention, the maintenance area comprises a plurality of maintenance areas, each for at least one exchange box, preferably at least one container. In this regard, the maintenance area, in particular each maintenance location, preferably comprises a maintenance corridor surrounding at least one exchange box, preferably at least one container. In this regard, the maintenance corridor is preferably designed to be accessible to workers and / or to maintenance or inspection equipment. This creates a maintenance area designed to accommodate at least standard exchange boxes, in particular standard containers, while enabling all-round inspection of the exchange boxes placed therein and allowing people and / or machines to access the exchange boxes, in particular containers, from all directions. In this regard, it is particularly advantageous to provide at least one maintenance position for a spare parts or tool exchange box. If two maintenance positions are arranged side by side, in a preferred embodiment of the present invention, the exchange box to be maintained can be placed in the first maintenance position, and a spare parts or tool exchange box, preferably of the same size, can be placed in the adjacent maintenance position to advantageously assist in the maintenance of the exchange box in the first maintenance position. Furthermore, if different spare parts or tool exchange boxes are provided, spare parts and / or tools for different purposes can be provided in a particularly simple manner to maintain the corresponding exchange boxes. Of course, if a maintenance location is configured and designed to receive a standard exchange box of a certain (standard) length, in a preferred embodiment of the present invention, the maintenance location is also configured and designed to receive an exchange box of a partial length, in particular, two exchange boxes of the corresponding partial length arranged one behind the other. In particular, in high-bay warehouses for loading, unloading, and temporarily storing standard containers, the system is typically designed to handle both 40-foot and 20-foot standard containers, so that preferably one 45-foot standard container, one 40-foot standard container, or two 20-foot standard containers can be placed in each rack level and / or maintenance location. Preferably, the rack levels are suitable for receiving 45-foot, 40-foot, and 20-foot containers. In this case, a 45-foot rack level can also receive two 20-foot standard containers, if necessary. In a related preferred embodiment of the present invention, at least one maintenance location has supports for the corner fittings of an exchange box, preferably a container, or supports for the corner fittings of two exchange boxes, preferably two containers, so that the exchange box can be placed only on its corner fittings, completely omitting other system structures, such as the bottom of the shelf or the bottom of the maintenance location. In this case, placing one or more exchange boxes, preferably containers, at a maintenance location also allows maintenance of the bottom side of the exchange box, preferably container, in particular, preferably from another maintenance location arranged below the maintenance location. As a result, the entire maintenance operation can be carried out in situ without having to further move the exchange box until the maintenance operation is completed, which further contributes to the goal of saving time and, if appropriate, costs. Preferably, the rack access system can be used to move the swap boxes, preferably containers, into and out of storage locations, preferably individual rack compartments, with their longitudinal sides parallel to the warehouse aisles. This creates a high-bay warehouse whose aisles and rack access system can be designed to be particularly narrow, thus limiting the overall space requirement of the high-bay warehouse to the necessary minimum. Preferably, the maintenance area within the high-bay warehouse is designed in the same manner, eliminating the need to rotate the swap boxes, preferably containers, within the HBS at any given time. In another preferred embodiment of the present invention, swap boxes, preferably containers, are transported by means of a rack access system suspended and supported from above. This creates a high-bay warehouse that essentially eliminates the need for a rack bottom, as the high-bay warehouse's support structure and the loading and unloading of containers generally do not require a rack bottom. In this regard, it is particularly preferred that the storage location, preferably the maintenance location, each have a support for at least the lower corner fittings of the exchange boxes, preferably containers. This allows the entire structure of the high-bay warehouse to be constructed particularly light, which ultimately leads to a reduction in the material consumption of the structure itself and its foundation. The transport of exchange boxes, preferably containers, by means of a rack access device in a suspended and upwardly supported manner is particularly advantageous if the rack access device comprises a carrying device for the exchange boxes, preferably containers, which is supported in a telescopic manner. Particularly advantageously, this telescopic movement can be carried out in a first direction and in a second direction opposite to the first direction, so that a single rack access device can be driven to at least two storage locations adjacent to the rack aisles and can load and unload exchange boxes, preferably containers there. In the case of loading and unloading empty containers, loading and unloading is particularly space-saving if the storage locations for empty exchange boxes, preferably empty containers, have a double-deep layout. In this case, the rack access device can place the preferably empty container from a first side into a storage location adjacent to the warehouse aisle or directly behind it, and can then remove it from these storage locations. In this case, such a high-bay warehouse is characterized by the following sequence: two storage locations arranged side by side, followed by a storage aisle, followed by four storage locations arranged side by side, followed by another storage aisle, etc. At least in the section for the storage of loaded containers, which usually does not use "double depth" or double-depth storage, such a high-bay warehouse section has a first module of storage locations arranged side by side, followed by a first storage aisle, followed by two modules of storage locations arranged side by side, followed by another storage aisle, etc. Preferably, the maintenance area has a width that does not exceed the width of four storage spaces in the double-deep layout. This provides space for a preferably circular maintenance aisle and, on the other hand, creates a safe distance between the part of the maintenance aisle facing the warehouse aisle and the warehouse aisle itself, so that even if the rack retrieval equipment is operating in the warehouse aisle next to the maintenance area, no worker injury or damage to the equipment can occur. Particularly preferably, in the case of double-deep storage of empty exchange boxes, preferably empty containers, if the maintenance area has two maintenance positions arranged side by side, its width does not exceed the width of four storage positions for empty exchange boxes, preferably empty containers, arranged immediately side by side. The high-bay warehouse of the present invention can be a transfer system for exchange boxes and incoming goods, in particular not only for handling exchange boxes (in particular standard containers), but also as part of a transfer system for collating partial loads of exchange boxes and transferring them to external transport vehicles. Preferably, the transshipment system is located at a seaport, inland port, or landside logistics center. In this regard, the high-bay warehouse is particularly preferably designed to handle more than 2,500 standard containers per hectare (TEU / ha) per year (2,500 TEU / ha), preferably more than 3,000 TEU / ha, and even more preferably more than 5,000 TEU / ha. TEU / ha is the industry standard unit of measurement for port logistics, particularly high-bay warehouse capacity. Prior art high-bay warehouses with external empty container stacking areas and operations using specialized vehicles (such as reach cranes or the like) have annual transshipment capacities of no more than 2,500 TEU / ha. The high-bay warehouse of the present invention, preferably fully automatically, can increase the transshipment capacity of loaded and empty containers beyond this conventional capacity. FIG1 shows a top view of a high-bay warehouse 1 according to the present invention, which in this case is only suitable for storing empty containers 2. The empty containers 2 are arranged double-deep in storage modules 9, so that two storage modules 9a and 9b, each receiving a large number of empty containers 2 arranged side by side and one above the other, are adjacent to a storage aisle 4. In these storage aisles 4, a rack retrieval device 5 can be moved along the entire length of the aisles 4. The rack retrieval device can receive containers from trucks 12 or transshipment center trucks 13 in a receiving area 11 and then deposit the containers 2 into suitable storage locations 15 within the storage modules 9 or into a maintenance area 6. The maintenance area 6 also has a large number of storage locations 6a to 6d, each of which can accommodate a container 2 and forms a circular maintenance aisle 7 around each container 2. The width of the two maintenance positions 6 a and 6 b arranged side by side in the maintenance area 6 is different from the width of the four empty containers 2 arranged substantially side by side in the four adjacent storage modules 9 . FIG2 shows a side view of the high-bay warehouse 1 shown in FIG1 , according to the present invention, designed only for receiving empty containers 2. To the right of receiving area 11, a rack retrieval system 5 receives empty containers 2 from the loading area of ​​a truck 12 and, using a load carrier 8, transports them in a suspended manner to any desired location within the high-bay warehouse 1, including, if necessary, to a maintenance area 6. The maintenance area 6 has six stacked maintenance locations 6a to 6f. The maintenance area 6 does not extend across the entire height of the high-bay warehouse 1. Instead, the high-bay warehouse 1 provides three storage locations 15 for empty containers 2 above the maintenance area 6. Storage locations 15 (if designed for standard 45-foot containers) can also accommodate two 20-foot containers 2a or containers of a special length 2b. FIG3 shows a cross-section of the high-bay warehouse 1 according to the present invention at the level of the maintenance area 6, which extends across the entire width of the high-bay warehouse 1, rather than its entire height. Specifically, three receiving locations 15 for empty containers 2 are located above the maintenance area 6, across the entire width of the high-bay warehouse 1. In these receiving locations 15 for empty containers 2, the empty containers 2 are stacked directly next to each other in a double-deep position. Within the warehouse aisles 4, a mobile rack access device 5 carries a carrying device 8, which, via a telescopically movable carrying arm 14, can transport the empty containers 2 to the left and right, suspended and supported, in a single-deep or double-deep position, to the desired storage location 15. It can be seen that the maintenance positions 6a to 6f each have a maintenance aisle 7 surrounding the empty container 2, wherein the width of two maintenance positions 6a, b arranged side by side is at most equivalent to the width of four storage positions for empty containers 2, so that the shelf retrieval device 5 can also freely enter the maintenance area 6 along the longitudinal extension of the warehouse aisle 4 without causing additional risks to the workers in the maintenance area 6. FIG4 shows a cross-sectional view of the high-bay warehouse 1 according to the present invention, as shown in FIG1 and FIG2 , showing the area containing storage modules 9 for empty containers 2. In this embodiment, containers 2 are stacked directly and directly adjacent to one another to form a plurality of storage modules 9, which form a large number of containers 2 stored in blocks arranged side by side and one above the other. In the "double-deep" stacking configuration shown here, each storage aisle 4 and the rack access device 5 located therein are generally adjacent to two storage modules 9a, 9b and 9c, 9d. Thus, in cross section, the order of the storage modules 9 and storage aisles 4 from left to right is essentially 2-1-4-1-4-1-4-1-4-2. This allows the rack access device 5 and its carrying device 8 with its telescopic carrying arm 14 to engage with two storage modules 9a, 9b and 9c, 9d, either to the left or to the right, and to deposit or retrieve a container 2. Finally, FIG5 shows a cross-section of the high-bay warehouse 1 according to the present invention at the height of the receiving area 11. The receiving area 11 has a lower transport level 16 for trucks 12 or other external transport vehicles (not shown), and an area above the transport level 16 containing a large number of storage modules 9, each formed by a row of stacking locations 15 for containers 2. The carrying device 8 of each rack access device 5 is arranged to be movable across the entire height of the high-bay warehouse 1, allowing the rack access device to grasp both the highest stacking location 15 in each storage module 9 and the container 2 in each transport level 16. Once the carrying arms 14 of the carrying devices 8 of the rack access device 5 have grasped a container 2, they can be retracted, allowing the container 2, suspended and transported by the rack access device 5, to be moved into the area of ​​the warehouse aisle 4, where it can then be moved essentially freely, both horizontally and vertically. In this case, when the container 2 is placed at the desired location, it is moved out of the level of the warehouse aisle 4 again by means of the carrying device 8 and moved into the module 9 or placed in a maintenance position (not shown). 1: High-bay warehouse 2: Container 4: Warehouse aisle 5: Shelf access equipment 6: Maintenance area 6a-f: Maintenance position 7: Maintenance aisle 8: Carrier 9a-d: Storage module 11: Receiving area 12: Truck 13: Transfer center truck 14: Carrier arm 15: Storage position 16: Transport level The present invention is described in detail below with reference to four figures, which illustrate preferred embodiments of the present invention.
