Description

1. Field of the invention

The invention relates to a high-bay warehouse for storing and retrieving swap bodies, preferably containers, with a plurality of storage locations for swap bodies, preferably containers, arranged horizontally next to one another and vertically one above the other, and storage aisles arranged between groups of storage locations and running parallel to one another, in each of which at least one storage and retrieval machine is movable back and forth, and which is set up and designed to move the swap bodies, preferably containers, vertically and horizontally and to move them into and out of the storage locations.

2. State of the art

High-bay storage (HBS) systems are well-known in the art and are widely used, particularly in transshipment facilities at sea or inland ports, or in land-based warehouse logistics in general. High-bay storage systems typically feature a multitude of horizontally adjacent and vertically stacked rack compartments, preferably separate rack compartments, and storage aisles arranged parallel between groups of rack compartments. Within the HBS, storage and retrieval machines are used to pick up containers, usually from a transfer point, for example, from a truck or terminal truck, or a preferably self-propelled carriage, which may be rail-mounted, and transport them from this pick-up point to the respective rack compartments.

The DE 10 2013 010 455 A1 discloses an AS/RS safety platform for the maintenance and servicing of storage and retrieval machines (SRMs) in high-bay warehouses. The AS/RS has a lower chassis, a mast extending vertically upwards from the mast, and an upper chassis arranged at an upper end of the mast, which interacts with a guide rail of a high-bay warehouse. In order to ensure safe maintenance and repair work, a safety platform is arranged in an area of an upper end section of the mast. In an operating state, this safety platform completely surrounds the mast and also bridges the aisle between the two opposite rack sections, at least in a partial section. The safety platform, or at least parts thereof, can be converted to an original state in which the AS/RS can be moved collision-free and used normally.

The WO 2023/ 115 090 A1 discloses a rack storage system with storage racks and rack aisles arranged therebetween, as well as maintenance aisles running in the rack aisle, some of which include walkable walkways arranged on superimposed maintenance levels. Pedestrian access points can be arranged on at least some of the walkable walkways between the maintenance aisles to enable ascent and/or descent between the maintenance aisles. Each pedestrian access point can be assigned an ascent and/or descent device.

An example of such a high-bay warehouse is in the WO 2015/ 124 342 A1 disclosed. In this high-bay warehouse, standard containers are picked up by a storage and retrieval machine at a transfer point within the high-bay warehouse and then transported by the storage and retrieval machine to a pre-determined shelf compartment and stored there. The containers are gripped from above while hanging and stored laterally in the respective shelf compartments using a telescoping system so that the long side of the container is aligned parallel to the storage aisle. This leads to maximum space utilization within the storage and retrieval system, as the storage aisles only need to be designed slightly wider than the respective end faces of the containers. This special handling and storage of containers, especially empty containers, also means that, with a suitable design of the telescoping systems on the storage and retrieval machines, two adjacent shelf compartments on each side can be served from each storage aisle, thus a total of four shelf compartments (“double deep”).

Within each storage aisle, a storage and retrieval machine is usually provided, via which each container can be transferred from a specified receiving position to the respective shelf compartment, and a container can also be removed from the shelf compartment and moved to a suitable transfer position in order to then be picked up by an external means of transport directly or indirectly with the interposition of suitable transfer devices.

The ability of the respective storage and retrieval machine to pick up, move and return a container, as well as the number of storage and retrieval machines within a storage aisle, is the determining factor for the handling capacity of the high-bay warehouse, which is usually finally determined during the design of the high-bay warehouse.

In warehouse logistics in general, loaded containers must not only be picked up, stored temporarily and removed again at the appropriate time not only will there be loads, but empty containers will also be moved and stored and retrieved. While it is advantageous to store loaded containers in separate, stacked shelves, thereby providing access to each individual container without the need to grasp containers stacked directly on top of each other from top to bottom, providing separate shelves for handling empty containers is not usually necessary, but can nevertheless be advantageous, at least temporarily, if necessary.

Empty containers must be maintained, repaired if necessary, and cleaned before further use, either at regular intervals or when damage is evident, or after the container's cargo has been unloaded, especially when it contains potentially contaminating or polluting goods. These processes, generally referred to as maintenance, are required for approximately 60% of all previously used containers after they have been emptied. In a HBS handling 100,000 containers annually, this means that 60,000 containers annually must be inspected, cleaned if necessary, and repaired or at least overhauled.

Typically, empty containers are removed from the high-bay warehouse either before being stored in a block storage facility or a high-bay warehouse, or after damage or similar is detected. They are picked up by external transport and transported to a designated maintenance area. After maintenance, they are then returned to the high-bay warehouse via the external transport. This approach proves to be inefficient, time-consuming, and costly, especially given the high number of loading and unloading operations required for maintenance.

3. Object of the invention

It was therefore an object of the invention to provide a high-bay warehouse capable of overcoming the disadvantages known from the prior art and, in particular, to create an efficient and time-saving way to enable the maintenance of swap bodies, in particular containers, particularly empty containers, quickly with minimal expenditure of time and with shortened transport distances. This object is achieved according to the invention with a high-bay warehouse comprising the features of claim 1. Advantageous embodiments of the invention are set forth in particular in the dependent claims.

4. Summary of the invention

According to the invention, the high-bay warehouse described above for storing and retrieving swap bodies, preferably containers, is characterized in that at least one maintenance area for swap bodies, preferably containers, is provided, which can be reached by at least one storage and retrieval machine and enables all-round access to the swap body, preferably container, deposited in the maintenance area. According to the invention, the maintenance area for swap bodies, preferably empty containers, is thus integrated into the high-bay warehouse itself, whereby storage or retrieval times can be shortened when maintenance requirements are identified. Furthermore, the swap bodies intended for maintenance can be transferred directly from the storage and retrieval machines provided for this purpose within the high-bay warehouse to the maintenance area and, after maintenance, can be stored within the high-bay warehouse or moved directly to a transfer point for external means of transport, for example in the form of trucks, terminal trucks, self-propelled carriages, cranes, or the like.

Maintenance within the meaning of the invention is understood to mean any form of inspection, be it optical or mechanical or, for example, by means of X-rays or ultrasound, both in the open and closed state, the performance of painting and varnishing work, metalworking, carpentry, cleaning work, and/or the inspection and, if necessary, repair of electrical components such as the cooling units of refrigerated containers. Maintenance within the meaning of the invention is also understood if, after the inspection and, if necessary, checking of components of the swap body, in particular the container, the performance of further actions such as cleaning or repair is deemed unnecessary.

According to the invention, the maintenance area can be integrated into any type of existing high-bay warehouse, even subsequently, requiring only a conversion or repurposing of existing areas of the high-bay warehouse. It is particularly preferred if the high-bay warehouse has at least one partial area for storing empty swap bodies, preferably empty containers. It is extremely preferred if the high-bay warehouse is generally designed to accommodate empty containers, which are then preferably stacked directly on top of each other and without providing separate shelf finders for each individual swap body, in particular container, and that the maintenance area has a single storage space, a pair of storage spaces arranged next to one another and/or one above the other, an entire row above one another. arranged parking spaces for swap bodies and/or a block of parking spaces for swap bodies, in particular containers, arranged one above the other and next to the other.

It is preferred if the swap bodies, preferably containers, can be adjusted to individual storage locations by the storage and retrieval machines. This allows easy access to each individual swap body, preferably loaded containers, without the swap bodies arranged above this specific swap body, preferably loaded container, having to be removed beforehand. As already described above, such handling and storage of empty swap bodies, in particular empty containers, is usually not necessary, so that empty swap bodies, in particular empty containers, can also be stacked directly on top of one another in designated shelving modules. A combination of both cases leads to maximum operational performance of the system. This means that a large proportion of the containers are stacked directly on top of one another and a small proportion of the containers can be stored in separate compartments. This is particularly interesting for containers that require maintenance.

It is preferred if the maintenance area is located in the immediate vicinity of at least the partial area for storing empty swap bodies, preferably empty containers, in the high-bay warehouse. Therefore, if the high-bay warehouse only provides a partial area for storing empty swap bodies, preferably empty containers, and is not entirely intended for storing empty swap bodies, preferably empty containers, according to the preferred embodiment of the invention, the immediate proximity of the maintenance area to the partial area for storing empty swap bodies shortens the transport routes within the high-bay warehouse, since the vast majority of maintenance work is performed on empty swap bodies, preferably empty containers, and not on swap bodies, preferably containers, in a loaded or at least partially loaded state.

In a preferred embodiment of the invention, the maintenance area has a plurality of maintenance stations, each for at least one swap body, preferably at least one container. In this context, it is extremely preferred if the maintenance area, in particular each maintenance station, has a maintenance walkway surrounding the at least one swap body, preferably the at least one container. In this context, it is particularly preferred if the maintenance walkway is designed to be walkable by a worker and/or accessible for a maintenance or inspection machine. This creates a maintenance area that is structurally designed to accommodate at least standard swap bodies, in particular standard containers, and at the same time allows a circumferential inspection of the swap body parked there and access to all sides of the swap body, preferably container, for humans and/or machines.

In this context, it is further preferred if at least one maintenance station is provided for a spare parts or tool interchangeable container. In the case of two maintenance stations arranged next to one another, for example, in a preferred embodiment of the invention, an interchangeable container to be serviced can be parked at a first maintenance station and a spare parts or tool interchangeable container, preferably of the same size, can be parked at a directly adjacent maintenance station, in order to advantageously support the maintenance of the interchangeable container at the first maintenance station. Furthermore, by providing different spare parts and tool containers, spare parts and/or tools tailored to different purposes can be provided in a particularly simple manner for the maintenance of the respective interchangeable container.

It is understood that if a maintenance station is designed and equipped to accommodate a standard swap body of a specific (standard) length, the maintenance station is also designed and equipped, in a preferred embodiment of the invention, to accommodate swap bodies with a partial length, and in particular for two swap bodies arranged one behind the other with corresponding partial lengths. Especially in high-bay warehouses for the storage, retrieval, and temporary storage of standard containers, the systems are usually designed to handle both 40-foot standard containers and 20-foot standard containers, so that preferably either one 45-foot standard container, one 40-foot standard container, or two 20-foot standard containers can be stored in each shelf compartment and/or each maintenance station. Shelf compartments are preferably provided to accommodate 45-foot, 40-foot, and 20-foot containers. If necessary, two 20-foot standard containers can also be accommodated in a 45-foot shelf compartment.

In a preferred embodiment of the invention in this regard, at least one maintenance station has supports for the corners of a swap body, preferably a container, or supports for the corners of two swap bodies, preferably two containers, so that the depositing the swap body can preferably be carried out exclusively on its corners, and other system-side structures such as shelving or maintenance station floors can be omitted entirely. In this case, setting down one or more swap bodies, preferably containers, at a maintenance station also allows the underside of a swap body, preferably a container, to be serviced, particularly preferably from another maintenance station located below the maintenance station. The entire maintenance can thus be carried out on site and without the need for further movement of the swap body until the maintenance work is completed, which further advantageously supports the goal of saving time and, where appropriate, costs.

It is preferred if the swap bodies, preferably containers, can be moved into and out of the storage locations, preferably separate rack compartments, by the storage and retrieval machine with their long sides aligned parallel to the storage aisles. This creates a high-bay warehouse whose storage aisles and storage and retrieval machines can be particularly narrow, so that the overall space requirement of the high-bay warehouse can be limited to the necessary minimum. It is preferred if the maintenance stations are designed in the same way within the high-bay warehouse, eliminating the need to rotate the swap bodies, preferably containers, at any time within the high-bay warehouse.

In a further preferred embodiment of the invention, the swap bodies, preferably containers, are transported suspended from the storage and retrieval machine and supported from above. This creates a high-bay warehouse that can essentially dispense with shelves, since the support structure on the high-bay warehouse side and the storage and retrieval of the containers can generally be carried out without shelves.

In this context, it is particularly preferred if the storage areas, preferably also the maintenance areas, each have supports for at least the lower corners of the swap bodies, preferably containers. This allows the entire structure of the high-bay warehouse to be constructed particularly lightly, which ultimately results in less material being used for both the structure itself and its foundations.

The suspended and top-supported transport of the swap bodies, preferably containers, by means of the storage and retrieval machines is particularly advantageous if the storage and retrieval machines have telescopically displaceable carrying devices for the swap bodies, preferably containers. It is extremely preferred if the telescopic displacement can take place both in a first direction and in a second direction opposite to the first direction, so that a single storage and retrieval machine can travel to at least two storage locations adjacent to the rack aisle and store and retrieve swap bodies, preferably containers, there. When storing and retrieving empty containers, particularly space-saving storage and retrieval is achieved with a double-deep arrangement of the storage locations for empty swap bodies, preferably empty containers. The storage and retrieval machine can then preferably deposit empty containers to a first side either in the storage locations directly adjacent to the storage aisle or in the storage locations arranged directly behind it, and move them out again from these. Such a high-bay warehouse would then be characterized by a sequence of two storage locations arranged directly next to one another, followed by a storage aisle, then again followed by four storage locations arranged directly next to one another, then again followed by another storage aisle, etc. In the case of at least partial areas for the storage of loaded containers, storage is not usually carried out at “double deep” or double-deep, as described above; such a partial area of the high-bay warehouse would then have a first module of storage locations arranged one above the other and next to one another, followed by a first storage aisle, then again followed by two modules of storage locations arranged next to one another and one above the other, these in turn followed by another storage aisle, etc.

It is preferred if the maintenance area has a width that does not exceed the width of four storage locations in the double-deep arrangement described above. This creates space for the maintenance aisles, which are preferably arranged circumferentially. It also creates a safety distance between the parts of the maintenance aisle facing the storage aisle and the storage aisle itself, so that even when operating storage and retrieval machines in the storage aisle in direct proximity to the maintenance area, no injuries to workers or damage to machines are to be expected.

When storing empty swap bodies, preferably empty containers, it is particularly preferred to have a double-deep storage area if the maintenance area has two maintenance bays arranged next to each other, the width of which does not exceed the width of four storage bays for empty swap bodies, preferably empty containers, arranged directly next to each other.

The high-bay warehouse according to the invention can be part of a transshipment facility for swap bodies and the goods stored therein, in particular a transshipment facility which not only handles swap bodies, in particular standard containers, but also serves as a transshipment center for assembling partial quantities of the swap body load and for transferring it to external means of transport.

It is preferred if the transshipment facility is located in a seaport, inland port, or a land-based logistics center. In this context, it is particularly preferred if the high-bay warehouse is designed to handle more than 2,500 standard containers per hectare per year (2,500 TEU/ha), preferably more than 3,000 TEU/ha, and most preferably more than 5,000 TEU/ha. The unit TEU per hectare presented here represents a standard measure for the capacity of port logistics and, in particular, of high-bay warehouses. The stacking areas for empty containers outside of high-bay warehouses known from the prior art and operation with vehicles specially designed for this purpose, such as reach stackers or the like, achieve an annual throughput of no more than 2,500 TEU/ha. The high-bay warehouse according to the invention can increase the throughput of both loaded and empty containers, preferably in a fully automated manner, beyond this known level.

6. Detailed description of the characters

1 shows a top view of a high-bay warehouse 1 according to the invention, which in the present case is intended exclusively for the storage of empty containers 2. The empty containers 2 are arranged in a double-deep manner in storage modules 9 such that two storage modules 9a, 9b, each of which accommodates a plurality of empty containers 2 arranged side by side and one above the other, are arranged adjacent to a respective storage aisle 4. In these storage aisles 4, storage and retrieval machines 5 can be moved over the entire length of the storage aisle 4 such that they can pick up containers from trucks 12 or terminal trucks 13 in the receiving area 11 and then place the containers 2 in suitable storage locations 15 within the storage modules 9 or move them into the maintenance area 6. The maintenance area 6, in turn, has a plurality of storage locations 6a to 6d, each of which can accommodate a container 2 and forms a circumferential maintenance aisle 7 around each container 2. The width of two maintenance stations 6a, 6b arranged next to one another within the maintenance area 6 is less than the width of four empty containers 2 arranged essentially directly next to one another in four adjacent storage modules 9.

2 shows a side view of the high-bay warehouse 1 according to the invention according to 1 for receiving only empty containers 2. On the right in the receiving area 11, the storage and retrieval machine 5 picks up an empty container 2 from the loading area of a truck 12 and transports this container 2 hanging by means of a carrying device 8 to any desired location within the high-bay warehouse 1, including, if necessary, into the maintenance area 6. The maintenance area 6 has six maintenance stations 6a to 6f arranged one above the other, whereby the maintenance area 6 does not extend over the entire height of the high-bay warehouse 1, but the high-bay warehouse 1 provides three storage locations 15 for empty containers 2 above the maintenance area 6. In the storage locations 15, if they are designed to accommodate 45-foot standard containers, two containers 2a with a length of 20 feet or containers 2b with special lengths can also be accommodated.

3 shows a section through a high-bay warehouse 1 according to the invention at the level of the maintenance area 6, wherein the maintenance area 6 extends over the entire width of the high-bay warehouse 1, but not over its entire height. Rather, above the maintenance area 6, across the entire width of the high-bay warehouse 1, three receiving locations 15 for empty containers 2 are provided. In these receiving locations 15 for empty con tainer 2, the empty containers 2 are stacked directly on top of one another and double deep, with a storage and retrieval machine 5 movable within a storage aisle 4 carrying a carrying device 8 which is able to transport the empty containers 2 to the left and right, either single or double deep, to the desired storage location 15 by means of telescopically displaceable support arms 14. It can be seen that the maintenance locations 6a to 6f each have a maintenance aisle 7 running around the empty container 2, with the width of two maintenance locations 6a, b arranged next to one another corresponding at most to the width of four storage locations for empty containers 2, so that the storage and retrieval machines 5 can move freely along the longitudinal extent of the storage aisles 4 and into the maintenance area 6 without posing an additional danger to the workers present in the maintenance area 6.

4 shows a section through the high-bay warehouse 1 according to the invention, as shown in 1 and 2 is shown, here by the area with the storage modules 9 for empty containers 2. In the present case, the containers 2 are stacked directly and immediately on top of one another to form a plurality of storage modules 9, which form a plurality of containers 2 arranged next to one another and one above the other, stored in blocks. In the "double deep" or "double deep" stacking form shown here, each storage aisle 4 with the storage and retrieval machine 5 provided therein is arranged in principle adjacent to two storage modules 9a, 9b and 9c, 9d, which in cross-section results in a sequence of the storage modules 9 and the storage aisles 4 from left to right in principle 2-1-4-1-4-1-4-1-4-2. In this way, the storage and retrieval machines 5 with their carrying device 8, which have telescopically moved support arms 14, can reach into two storage modules 9a, 9b and 9c, 9d both to the left and to the right and can set down or grasp containers 2.

5 Finally, Fig. 1 shows a cross-section through a high-bay warehouse 1 according to the invention at the level of the receiving area 11. The receiving area 11 has a lower traffic level 16 for the entry of trucks 12 or other (not shown) external means of transport, as well as an area arranged above the traffic level 16 with a plurality of storage modules 9, each of which is formed from a row of stacking positions 15 for containers 2. The carrying devices 8 of each storage and retrieval machine 5 are provided so that they can be moved over the entire height of the high-bay warehouse 1 that they can grasp both the highest stacking position 15 in each storage module 9 and the containers 2 present in the traffic level 16. Once the support arms 14 of the support device 8 of the storage and retrieval machine 5 have grasped a container 2, the support arms 14 are telescopically retracted, so that a container 2 transported suspended from the storage and retrieval machine 5 is inserted into the area of a storage aisle 4 and can then be moved essentially as desired, both horizontally and vertically. When the container 2 is set down at the desired location, it is then moved out of the plane of the storage aisle 4 again by means of the support device 8 and either inserted into a module 9 or placed on a maintenance station (not shown).
