Description

Technical Field

[0001] The present invention relates to a storage system according to the preamble of claim 1, and a method for storing physical objects in such a storage system using the steps of claim 8. Background Technology

[0002] In the field of warehousing and logistics, or storage logistics, automated storage systems capable of storing a wide variety of physical goods are known. These automated storage systems are able to automatically store and retrieve physical goods, at least partially, within the storage volume of the storage system, according to the storage and retrieval sequence.

[0003] In automated storage systems, storage handling vehicles, also known as storage and retrieval equipment, horizontal handling equipment, or shuttles, are commonly used, depending on the application. The items to be stored sometimes enter the storage volume directly or with the aid of storage aids. However, the use of available space in storage systems is not optimal because the travel paths of shuttles or rack handling equipment occupy a significant amount of space. Furthermore, each storage location in existing storage systems typically has a fixed volume, independent of the volume of the stored items. Small items are often stored in large quantities in a single container to store a large number of items in a common storage location. Containers are known in the prior art for storing several identical items; for example, containers with subdivisions to create separate slots for different items, or mixed containers storing different items. However, this complicates the storage logistics and causes delays in the storage system's handling of items, as these items can only be stored and retrieved together.

[0004] Furthermore, so-called automated grid storage systems are known, which achieve higher volume utilization by avoiding aisles for storage handling vehicles. Here, the grid is provided by horizontal longitudinal and transverse tracks. The grid is supported by vertical supports at the intersections of the longitudinal and transverse tracks. Two longitudinal tracks and two transverse tracks, along with the shelf supports, form a vertical storage shaft, providing containers stacked one on top of another for storing items. The topmost container in the stack can be accessed using an orthogonally movable robot, or the robot can be used to reposition or remove the container within the grid storage. Here, the volume of the storage location is also limited by the volume of each container. If only one small item is stored in a container, the volume of the container used to receive that item is again not optimally utilized, creating dead space. Another proven drawback is that the entire load of the container stack falls on the bottom container. Therefore, the static dimensions of the containers must be able to withstand this high load. Containers of this size are expensive to manufacture. It should also be noted that in the event of a fire, containers stored close together and stacked one on top of another have a negative impact because fire extinguishing measures cannot effectively reach the fire source. Summary of the Invention

[0005] The purpose of this invention is to eliminate the above-mentioned disadvantages of the prior art and to provide an economical and efficient storage system and method for storing physical objects, which can effectively utilize space to store physical objects.

[0006] This is achieved by providing a storage system having the features of claim 1 and a method for storing physical objects having the features of claim 8.

[0007] The storage system according to the invention includes at least one rack having a plurality of rack supports extending substantially vertically and disposed on a base. Furthermore, the storage system includes at least one storage handling trolley and at least two storage auxiliary tools, as well as an operating layer disposed at the upper end of the rack and a storage volume disposed below the operating layer. The storage handling trolley is arranged to be movable within the operating layer and configured to introduce and remove the storage auxiliary tools from the storage volume.

[0008] Each storage auxiliary tool has an engagement device, and the rack support has receiving devices arranged within the storage volume. The engagement device can move between a locked state and a released state. In the locked state, the engagement device is substantially fixed in at least some of the receiving devices, holding the corresponding storage auxiliary tool in its storage position within the storage volume. In the released state, the engagement device is released from the receiving devices. The storage handling cart is configured to move the engagement device between the locked and released states, starting from the operating level. Furthermore, by moving the engagement device between the released and locked states, the storage auxiliary tool can be positioned or fixed in different storage locations within the storage volume, so that the distance between two storage auxiliary tools in the vertical direction within the rack can be adapted to the space requirements of the corresponding items stored on the storage auxiliary tool. This significantly improves the space utilization within the storage system.

[0009] The storage handling vehicle preferably includes a load receiving device that can move substantially vertically within the storage volume and can be coupled to one of the storage auxiliary tools for introducing and removing the storage auxiliary tool from the storage volume. This provides the advantage that, in order to secure the storage auxiliary tool in or release it from the storage location, it is not necessary to introduce the storage handling vehicle itself into the storage volume.

[0010] According to a preferred embodiment of the storage system of the present invention, the load receiving device is configured to preferably move the engagement device from a locked state to a released state during coupling with the storage auxiliary tool, and / or preferably move the engagement device from a released state to a locked state during decoupling from the storage auxiliary tool. This has the advantage that no separate device is required to move the engagement device between the locked and released states, and that the fixing or releasing of the storage auxiliary tool at the storage location occurs simultaneously with the connection or release of the load receiving device.

[0011] The receiving device is preferably configured as a recess, indentation, or seam within the shelf support. This offers the advantage of simple and inexpensive manufacturing of the receiving device.

[0012] The engagement device is preferably configured as a hook, bolt, or sector plate arranged on a shaft. Furthermore, in the locked and / or released states, they are preferably pre-tensioned by springs. This has the advantage that the locked and released states can be switched with simple movement. Additionally, the pretension in the released state prevents the engagement device from accidentally locking, or the prestress in the locked state prevents the engagement device from accidentally releasing. Preferably, the engagement device of one of the storage aids in the locked state engages with the receiving device of a plurality of shelf supports positioned opposite each other on a single floor.

[0013] The storage auxiliary tools are also preferably stackable. This has the advantage that the storage auxiliary tools can be stored in a space-saving manner. Furthermore, due to their stackability, the storage auxiliary tools can be stored directly in the storage system in a space-saving manner. The engagement devices of the bottom storage auxiliary tools are set to a locked state, which holds them in their storage position. Then, other storage auxiliary tools are placed or stacked on top of this bottom storage auxiliary tool, with the engagement devices of these other storage auxiliary tools remaining in a released state. When the stacked storage auxiliary tools are removed, they are removed one by one from the stack, starting from the top.

[0014] The method according to the invention for storing physical objects in a storage system according to the invention includes the following steps:

[0015] • Determine the first storage height of the first physical object to be stored in the storage system;

[0016] • Introduce or apply the first physical object to or onto a first storage aid selected from the storage aids of the storage system;

[0017] • Connect the first storage auxiliary tool to the storage operation vehicle;

[0018] • The first storage auxiliary tool is introduced into the first storage position in the storage volume by the storage operation vehicle, at which time the engagement device of the first storage auxiliary tool is in the released state;

[0019] • When decoupling the first storage auxiliary tool from the storage operation vehicle, the engagement device of the first storage auxiliary tool is moved from the released state to the locked state to fix the first storage auxiliary tool in the first storage position;

[0020] • Connect the second storage auxiliary tool selected from the storage auxiliary tools of the storage system to the storage operation vehicle;

[0021] • The second storage auxiliary tool is introduced into the second storage position in the storage volume by a storage operation vehicle, at which time the engagement device of the storage auxiliary tool is in the released state, wherein the second storage position is located at a vertical distance of at least the first storage height above the first storage position;

[0022] • When decoupling the second storage auxiliary tool from the storage operation vehicle, the engagement device of the second storage auxiliary tool is moved from the released state to the locked state to fix the second storage auxiliary tool in the second storage position.

[0023] A first storage height for the first physical object is determined, and a second storage location is selected at a vertical distance above the first storage location at least the first storage height, allowing the distance between the first and second storage locations to vary based on the space required for the physical object to be stored in the first storage location.

[0024] According to a preferred embodiment of the method of the invention, the space required for extinguishing agents or extinguishing inhibitors is taken into account in the vertical distance between the first and second storage locations. This allows for the automatic consideration of the space required for different extinguishing agents or extinguishing inhibitors between storage locations, ensuring sufficient supply and distribution of extinguishing agents in the storage system in the event of a fire.

[0025] The movement of at least one engagement device of the storage aid in the storage system between a locked state and a released state is preferably achieved by rotating the engagement device about a rotation axis arranged substantially along the route of the shelf support. This has the advantage of performing the movement between the released and locked states in a mechanically simple manner, starting from the operating level.

[0026] Preferably, the movement of at least one engagement device of the storage auxiliary tool of the storage system from a locked state to a released state is achieved by lifting the storage auxiliary tool from a first storage location or a second storage location. This simplifies the procedure for removing the corresponding storage auxiliary tool from the storage location, as no separate method step is required to move the engagement device from the locked state to the released state.

[0027] The first physical item can be a storage aid, a stack of storage aids, or an object. In this way, the storage aid can be stored in the storage system and removed when needed. This significantly reduces the space required to prepare the storage aid.

[0028] Preferably, the method according to the invention includes the following additional steps:

[0029] • Determine the second storage height of the second physical object to be stored in the storage system;

[0030] • Introduce or apply a second object to or onto a second storage aid.

[0031] In this way, the second physical object to be stored is placed in the storage system, and its second storage height is determined. This allows the space requirements of each physical object stored in the storage system to be taken into account. Attached Figure Description

[0046] Figure 6c Showing according to Figure 6b The load receiving device is shown, and the actual object received by the load receiving device is also shown. Detailed Implementation

[0047] exist Figure 1 and Figure 2 The storage system 1 according to the invention is shown in cross-section as an external view. The storage system 1 includes at least one shelf 2 having a plurality of shelf supports 3 disposed on a base and extending substantially vertically or at least segmentally. Furthermore, the storage system 1 includes at least one storage handling trolley (not shown) and at least two storage auxiliary tools 4. Additionally, the storage system 1 includes an operating layer disposed at the upper end of the shelf 2 and a storage volume 5 disposed below the operating layer. The storage handling trolley is arranged to be movable within the operating layer and configured to introduce and remove the storage auxiliary tools 4 from the storage volume 5. According to the invention, each storage auxiliary tool 4 has an engagement device 6, and the shelf supports 3 have receiving devices 7 disposed within the storage volume 5. For example, in Figure 3b and Figure 4b The coupling device 6 is shown in detail, wherein Figure 3d and Figure 4dA receiving device 7 is also shown. The engaging device 6 is movable between a locked state and a released state. In the locked state, the engaging device is substantially fixed in at least some of the receiving device 7 and holds the corresponding storage aid 4 in a storage position in the storage volume 5. In the released state, the engaging device 6 is released from the receiving device 7. Figures 3a to 3d The engagement device 6 is shown in a locked state. Figures 4a to 4d The engagement device 6 is shown in the released state. The storage handling vehicle is configured to move the engagement device 6 between the locked and released states, starting from the operating layer. Due to the possibility of moving the engagement device 6 between the released and locked states starting from the operating layer, the storage aids 4 can be secured to different storage positions within the storage volume 5, so that the distance A between two vertically consecutive storage aids 4 in the shelf 2 can accommodate the space requirements of the corresponding items 8 stored on the storage aids 5. In this way, the space utilization within the storage system 1 will be greatly improved.

[0048] According to a preferred embodiment of the storage system 1 of the present invention, the storage handling vehicle has a load receiving device 9, which can be moved substantially vertically within the storage volume 5 and can be coupled to one of the storage auxiliary tools 4 for introducing and removing the storage auxiliary tools 4 from the storage volume 5. This load receiving device 9... Figures 6a to 6c As shown in the diagram. The load receiving device 9 is lowered from the operating layer into the storage volume 5 via a storage operating cart (not shown). In this case, as... Figure 6b and Figure 6c As shown, the storage auxiliary tool 4 is already coupled to the load receiving device 9, or the load receiving device 9 is not yet occupied and is only coupled to the storage auxiliary tool 4 located there upon arrival at the storage location. For example, the storage handling vehicle can use a cable pull (not shown) to lower the load receiving device 9 into the storage volume 5. This has the advantage that the storage handling vehicle itself does not need to enter the storage volume 5, and the storage auxiliary tool 4 can be quickly introduced into and removed from the storage volume 5. Figures 6a to 6cAs shown, the load receiving device 9 can be coupled to the storage aid 4 via, for example, a retaining device 10 in the form of scissors, wherein when the load receiving device 8 is lowered onto the storage aid 4, the retaining device 10 engages with a corresponding recess or groove 11 in the storage aid 4. Thus, once the load receiving device 9 is lowered onto the storage aid 4, the load receiving device 8 is automatically coupled to the storage aid 4. The load receiving device 9 is preferably configured to move the engaging device 6 from a locked state to a released state during coupling with the storage aid 4, and / or preferably to move the engaging device 6 from a released state to a locked state during decoupling from the storage aid 4. This can be achieved, for example, by a mechanical folding or rotating mechanism not shown separately in the figure. This prevents the engaging device 6 of the load receiving device 4 from remaining in a locked state once coupled to the load receiving device 9. Figure 6c As shown, the load receiving device 9 may have a receiving space 12 adapted to the maximum size of the storage handling vehicle. Alternatively, the load receiving device 9 may be configured to open at the top, so that the height of the physical object 8 stored or to be stored on the load receiving device 9 is unrestricted.

[0049] The receiving device 7 of the shelf support 3, which engages with the engaging device 6 of the storage aid 4 in the locked state, is preferably configured as a recess, indentation, or seam within the shelf support 3. For example, in Figure 3d and Figure 4d The illustration shows a variation of the embodiment in which the receiving device 7 is configured as a slot. This simplifies the manufacture of the shelf support 3, thereby keeping the overall cost of the storage system 1 low. The engaging device 6 can also be configured, for example, as a hook, bolt, or sector plate arranged on a shaft. Figures 3a to 4d In the embodiment variation of the storage system 1 according to the invention shown, the engagement device 6 is configured as a sector-shaped disk. This makes the structure of the engagement device 6 and the receiving device 7 particularly flexible, yet also easy to manipulate. Furthermore, the engagement device 6 can preferably be pre-tensioned by a spring (not shown) in the locked and / or released states. In this way, the risk of erroneous operation can be prevented. Figure 5 The diagram illustrates an alternative embodiment variant of the engaging device 6, wherein the engaging device 6 is configured as a hook. For example, in this embodiment variant, the engaging device 6 can be released from its locked state by simply lifting the storage aid 4. The hook then retracts back into the space within the storage aid 4.

[0050] In the storage system 1 according to the invention, the engagement device 6 of one of the storage aids 4 in the locked state preferably engages with the receiving devices 7 of a plurality of shelf supports 3 located opposite each other in a single layer. As shown, for example, a storage aid 4 with a square base can be provided, wherein engagement devices 6 are provided at each corner. This will achieve a particularly stable fastening of the storage aid 4 in the locked state and will ensure a high load-bearing capacity.

[0051] The storage aid 4 is preferably stackable. For example, in Figure 2 The diagram illustrates how multiple storage auxiliary tools 4 are stacked vertically within a storage location in storage volume 5. These stacked storage auxiliary tools 4 thus form a physical object 8, which is stored on top of the bottom storage auxiliary tool 4 in storage system 1. In this configuration, only the engagement device 6 of the bottom storage auxiliary tool 4 is locked, while the other storage auxiliary tools 4 forming the physical object 8 are placed on top of it. The engagement devices 6 of the other storage auxiliary tools 4 are released. By removing the storage auxiliary tools 4 one by one from the top of the stack, starting with the storage auxiliary tool closest to the operating layer, for example by means of a load receiving device 9, the storage auxiliary tools 4 can be removed from the stack again. This significantly reduces the space required to store the storage auxiliary tools 4.

[0052] The method according to the invention for storing an object 8 in a storage system 1 according to the invention includes determining a first storage height H1 of the first object 8 to be stored in the storage system. This determines the space requirements of the first object 8. This determination can be made, for example, by measurement, or the determination can be stored in a database. Furthermore, the first object 8 is applied to or introduced into a first storage aid 4 selected from the storage aids 4 of the storage system 1. The first storage aid 4 is then connected to a storage handling vehicle and introduced into a first storage position in the storage volume 5 via the storage handling vehicle, at which point the engagement device 6 of the first storage aid 4 is in a released state. If the first storage aid 4 is in the first storage position, the engagement device 6 of the first storage aid 4 is moved from the released state to a locked state to secure the first storage aid 4 in the first storage position. Afterwards, or simultaneously, the first storage aid 4 is decoupled from the storage handling vehicle. Subsequently, the second storage auxiliary tool 4, selected from the storage auxiliary tools 4 of the storage system, is coupled to the storage operating vehicle, and introduced into the second storage position in the storage volume 5 via the storage operating vehicle, at which point the engagement device 6 of the second storage auxiliary tool 4 is in a released state. The second storage position is located at a vertical distance A at least a first storage height H1 above the first storage position. The advantage of this is that the distance A between the first and second storage positions is selected based on the space requirements of the first physical object 8. This allows the storage position to adapt to the actual space requirements of the physical object 8 to be stored in the storage system 1 according to the invention. Thus, the free space in the storage volume 5 is reduced. Subsequently, the engagement device 6 of the second storage auxiliary tool 4 is moved from the released state to the locked state to secure the second storage auxiliary tool in the second storage position and decouple the second storage auxiliary tool 4 from the storage operating vehicle.

[0053] Preferably, according to the method of the invention, the space requirements for fire extinguishing agent or fire suppressant (not shown in the figure) are taken into account in the vertical distance A between the first storage location and the second storage location. This ensures that in the event of a fire, sufficient fire extinguishing agent or fire suppressant can be introduced into the storage volume 5 and can reach all stored items 8.

[0054] Preferably, at least one engagement device of the storage aid for moving the storage system 1 between a locked state and a released state is performed by rotating the engagement device 6 around a rotation axis D arranged substantially along the route of the shelf support 3. This ensures that the engagement device 6 can be easily operated. The rotation axis D can be... Figure 3b and Figure 4b As seen in the figures, for example, for rotational purposes, as shown in these figures, a shaft can be provided to connect to a coupling device 5 in the form of a sector disk, the shaft including a coupling element at the end opposite to the sector disk.

[0055] Alternatively, at least one engagement device 6 of the storage aid 4 in the storage system 1 can be moved from a locked state to a released state by lifting the storage aid 4 from the first storage location or the second storage location. This reduces the likelihood that one of the storage aids 4 will get stuck in the corresponding storage location and reduces the sensitivity of the method according to the invention to errors. The first object 8 can be the storage aid 4, such as... Figure 2 As shown, the storage aid 4 represents a stack or items. Typically, the first physical item 8 can be an item or any physical item 8 that is stored in and / or retrieved from the storage system 1 using the method according to the invention.

[0056] Preferably, in the method according to the invention, a second storage height H2 of the second physical object 8 to be stored in the storage system is determined, and the second physical object 7 is introduced or applied to or onto the second storage aid 4. In this way, the storage height of each physical object 8 stored using the method according to the invention is determined. Like the first physical object 8, the second physical object 8 can also be the storage aid 4, a stack of storage aids 4, or an item. Generally, the second physical object 8 can be an item or any physical object 8 stored in and / or removed from the storage system 1 using the method according to the invention.
