Abstract
Description
Technical Field
[0001] This invention relates to a warehouse layout method, and more particularly to a planar warehouse layout method, belonging to the field of warehouse layout management technology. Background Technology
[0002] There are generally two layout methods for existing flat warehouses: single-row layout and dense layout.
[0003] Single-column layout as follows Figure 1 As shown by the dotted line in the schematic diagram of a single-row layout of a flat warehouse in the prior art, there is one or more aisles inside the flat warehouse. Each aisle is used for goods handling tools such as pallet trucks, forklifts, and pallet jacks, or AGVs for loading, unloading, and transporting goods in and out. At the same time, a row of goods or a row of platform boards or a row of mobile single-layer or multi-layer shelves are arranged on both sides of each aisle for storing goods.
[0004] This flat warehouse layout method is suitable for warehouse management where the items in each storage location, each platform, or each shelf are different, facilitating the storage and retrieval of different items.
[0005] However, flat warehouses laid out in this way have a low volume ratio, occupy a lot of space, have low storage efficiency, and are not economically efficient.
[0006] Dense layout methods such as Figure 2 As shown in the dotted-line area diagram of the dense layout of a flat warehouse in the existing technology, there is one or more aisles inside the flat warehouse. On both sides of each aisle, there are multiple rows of goods, multiple rows of platform boards, or multiple rows of shelves for stacking goods. This layout can greatly increase the warehouse's volume ratio, store more goods, and improve storage efficiency.
[0007] However, with this layout, if the items stored in each row are different or the specifications and batch numbers of the items are inconsistent, it is very easy to cause storage chaos, and the items stored in the back row are not easy to retrieve, resulting in inconvenience in access.
[0008] Furthermore, in this layout, even if the same type of items are stored in each column of a multi-row layout, the difference in the time when items are stored or retrieved in each column will cause some items in some columns to be left unused and unable to be stored as new items. This results in some storage locations in those columns being left empty and wasted, which is known in the industry as the honeycomb effect or honeycomb phenomenon. This leads to a reduction in the actual usable area of the flat warehouse and a decrease in the volume ratio.
[0009] In summary, the existing flat warehouse layout has the following main problems:
[0010] First, the warehouse has low space utilization;
[0011] It is estimated that the actual total storage area of a flat warehouse laid out in the above-mentioned single-row manner accounts for only 30% to 35% of the total warehouse area, which is commonly referred to as the floor area ratio.
[0012] While a densely laid-out flat warehouse can theoretically achieve a floor area ratio of 70%, in practice, due to the honeycomb effect, it can only reach 40-50%.
[0013] Second, the warehouse has poor flexibility in storing goods;
[0014] When there are many different types of items to be stored, the above-mentioned single-column layout can generally only be used, resulting in a very low volume ratio.
[0015] If a high volume ratio is desired and the above-mentioned dense layout of the flat warehouse is adopted, in actual use, the presence of small or missing items may lead to a honeycomb effect, and the actual volume ratio may not be very high. This puts the storage of items in the flat warehouse in a dilemma, making it impossible to flexibly allocate and adapt to the ever-changing needs of item storage and entry and exit, meet user needs, and obtain better economic benefits.
[0016] Third, the racks used in the above two layouts of flat warehouses are usually mobile single-layer or multi-layer racks. However, mobile single-layer or multi-layer racks are easily damaged, unstable and occupy a large area, which will lead to a decrease in the volume ratio and an increase in storage costs and warehouse management costs. Summary of the Invention
[0017] To overcome the shortcomings of existing related technologies, this invention provides a layout method for a planar warehouse, the purpose of which is:
[0018] By making full use of existing flat warehouse resources and through innovative layout, we can adapt to complex inventory scenarios involving multiple varieties, multiple batches, and uncertain batches or quantities of goods, thereby improving the volume ratio of flat warehouses and the efficiency of goods storage and retrieval, reducing storage costs and warehouse management costs, and improving economic benefits.
[0019] To achieve the above objectives, the present invention provides the following technical solution:
[0020] A layout method for a flat warehouse is used to construct the division and management system of the storage area of the flat warehouse. The flat warehouse is equipped with a platform and / or a shelf for stacking and storing goods, wherein the area occupied by one platform or shelf is one storage location.
[0021] The layout method for the aforementioned flat warehouse specifically includes the following steps:
[0022] Survey and draw a warehouse floor plan of the aforementioned flat warehouse or obtain and verify an existing warehouse floor plan of the aforementioned flat warehouse;
[0023] Based on the warehouse floor plan and in accordance with the requirements of the relevant department's regulations on warehouse management, the actual usable storage area and its usable storage size of the warehouse are determined.
[0024] At least one item storage block shall be divided within the actual storage area and its usable storage area;
[0025] Within each of the aforementioned item storage blocks, one or more parallel aisles are provided, and the areas on both sides of the aisles are arranged as storage aisles for placing the platform and / or the shelves, wherein:
[0026] When there is only one channel, one side of the channel is set as a storage lane for scattered items, while the other side of the channel is set as a storage lane for bulk items.
[0027] When there are two channels, the area between the two channels is set as a bulk goods storage lane, and the areas on opposite sides of each of the two channels are set as loose goods storage lanes.
[0028] When there are three channels, the three channels are arranged in sequence, and the opposite sides of the first and third channels are set as scattered item storage lanes, while the area between the first and third channels is set as two batch item storage lanes with the second channel as the dividing channel.
[0029] When there are three or more channels, the channels are sequentially ordered. The area on the side opposite to the other channels of the first channel is set as a storage lane for loose items. Then, starting from the side where the first channel and the second channel face each other, the storage lanes are arranged sequentially with each channel as the boundary, in the manner of one storage lane for bulk items, one storage lane for loose items, another storage lane for loose items, and another storage lane for bulk items. Adjacent storage lanes for loose items are not divided but are combined into a double row of storage lanes for loose items.
[0030] Along the direction of each of the aforementioned passageways, rows of raised platforms and / or rows of shelves are respectively installed in each of the aforementioned scattered goods storage aisles and each of the aforementioned bulk goods storage aisles, wherein:
[0031] The individual item storage aisles, whether independently set up or against a wall, shall be arranged with 1 to 3 rows of platform panels and / or shelving. The interior of two adjacent double-row individual item storage aisles that have been merged into one shall be arranged with no more than 4 rows of platform panels and / or shelving, and the number of storage units in each individual item storage aisle shall not exceed 1 / 3 of the number of storage units in the bulk item storage aisle.
[0032] Further:
[0033] The width of the passage is sufficient to accommodate one or more of the following transport vehicles used in the flat warehouse when moving items into and out of the item storage area: forklifts, pallet trucks, AGVs, and shuttles.
[0034] Furthermore, the layout method for the flat warehouse also includes:
[0035] Separator;
[0036] The dividing channel is located within the loose goods storage lane and / or the bulk goods storage lane, and the loose goods storage lane and / or the bulk goods storage lane are divided into two or more loose goods storage units and / or bulk goods storage units by the dividing channel.
[0037] Furthermore, the partition is perpendicular to the passage, and the width of the partition is sufficient to accommodate one-way passage of forklifts or pallet trucks, or AGVs, shuttles, or other transport vehicles used in the flat warehouse when transporting items into and out of the loose items storage unit and / or the bulk items storage unit.
[0038] Furthermore, the shelf is a single-layer shelf.
[0039] Furthermore, multiple single-layer shelves are longitudinally connected to form a single-layer continuous longitudinal shelf.
[0040] Furthermore, the single-layer continuous longitudinal rack consists of two parallel beams fixedly installed on the floor of the flat warehouse, and the two adjacent beams of the multiple parallel single-layer continuous longitudinal racks are connected and fixed to each other by connecting members.
[0041] Furthermore, after the platform or cargo packaging box is placed on top of the single-layer continuous longitudinal rack, its bottom has the height and space to allow an empty AGV or shuttle to pass freely.
[0042] Furthermore, in the aforementioned layout method for a planar warehouse:
[0043] The aisles for storing scattered items and the aisles for storing bulk items are dynamically allocated and managed using a warehouse management system, namely:
[0044] The warehouse management system allocates incoming loose items to designated storage aisles, and also allocates incoming bulk items to designated storage aisles.
[0045] The warehouse management system performs real-time statistical analysis on the existing items in the aisles for scattered items and the aisles for bulk items. It then redistributes and reorganizes the remaining scattered inventory items after partial shipments from the bulk item aisles.
[0046] The warehouse management system locates storage locations within the aisles for the scattered inventory items, allocates the scattered inventory items from the aisles for bulk items to the scattered inventory items, and issues a transfer instruction; and
[0047] During the off-peak hours when items are moving in and out of the flat warehouse, the handling and sorting of the remaining scattered inventory items are carried out.
[0048] Furthermore, the flat warehouse is also equipped with AGVs. The transfer command is sent to the AGVs, and the handling and sorting work is completed by the AGVs according to the transfer command given by the warehouse management system.
[0049] Compared with the prior art, the beneficial effects and significant progress of the present invention are as follows:
[0050] 1) The present invention provides a layout method for a flat warehouse, which involves dividing at least one item storage block within the usable actual storage area and storage area of an existing flat warehouse, setting up aisles within these item storage blocks, and setting up storage aisles on both sides of the aisles as storage spaces for placing platform panels and / or shelves, wherein:
[0051] When there is only one passageway, one side of the passageway is set up as a storage lane for scattered items, and the other side is set up as a storage lane for bulk items.
[0052] When there are two channels, the area between the two channels is set as a bulk goods storage lane, and the opposite sides of each channel are set as loose goods storage lanes.
[0053] When there are three channels, the first and third channels are respectively set up as scattered item storage lanes on their opposite sides, and the area between the first and third channels is set up as two batch item storage lanes with the second channel as the dividing channel.
[0054] When there are three or more passages, the side of the first passage facing away from other passages is set as a storage lane for loose items. Starting from the side of the first passage and the second passage facing each other, the passages are arranged in the following order: one storage lane for bulk items, one storage lane for loose items, another storage lane for loose items, and another storage lane for bulk items.
[0055] Arrange 1 to 3 rows of platform panels and / or shelves in the aisles for scattered items that are set up independently or against the wall, and the number of storage units in each aisle for scattered items shall not exceed 1 / 3 of the number of storage units in the aisle for bulk items, so as to flexibly cope with the storage of various bulk items.
[0056] 2) The layout method of the flat warehouse provided by the present invention makes full use of the resources of the existing flat warehouse. Through innovative layout, it can adapt to the complex inventory scenario of storing multiple varieties, multiple batches, and items with uncertain batches or quantities. It improves the volume ratio of the flat warehouse and the efficiency of storing and retrieving items, reduces storage costs and warehouse management costs, thereby improving the economic benefits of the warehouse.
[0057] 3) The layout method of the flat warehouse provided by the present invention has a novel and unique layout design, and the provided technical solution is simple and practical. It can effectively improve the volume ratio and the efficiency of goods storage and retrieval in the flat warehouse. It has constructed a brand-new layout mode for the division of goods storage areas in the flat warehouse and its management system, which is highly inspiring and has great value for promotion and application.

[0083] Example
[0084] This embodiment provides a layout method for constructing a flat warehouse layout system for dividing and managing the storage areas of goods within the flat warehouse. The flat warehouse is equipped with platforms and / or shelves for stacking and storing goods, wherein the area occupied by one platform or one shelf is one storage location.
[0085] The layout method for a flat warehouse provided in this embodiment specifically includes the following steps:
[0086] Survey and draw a warehouse floor plan of a flat warehouse or obtain and verify an existing warehouse floor plan;
[0087] Based on the warehouse floor plan and the requirements of the relevant department's warehouse management standards, determine the actual usable storage area and its usable storage size for the warehouse.
[0088] At least one item storage block 100 shall be divided within the actual storage area and its usable storage area;
[0089] Within each item storage block 100, one or more parallel aisles 111 are provided, and the areas on both sides of the aisle 111 are arranged as storage aisles for placing platform panels 131 and / or shelves 132, wherein:
[0090] like Figure 3 A schematic diagram of a single-aisle warehouse layout obtained by applying the layout method of a planar warehouse provided by this invention is shown below:
[0091] When there is only one channel 111, one side of channel 111 is set as a storage lane 121 for scattered items, while the other side of channel 111 is set as a storage lane 122 for bulk items.
[0092] like Figure 4 A schematic diagram of a dual-aisle warehouse layout obtained by applying the layout method of a planar warehouse provided by this invention is shown below:
[0093] When there are two channels 111, the area between the two channels 111 is set as the bulk item storage lane 122, and the areas on opposite sides of the two channels 111 are set as the scattered item storage lane 121.
[0094] like Figure 5 A schematic diagram of a three-channel planar warehouse layout obtained by applying the planar warehouse layout method provided by this invention is shown below:
[0095] When there are three channels 111, the three channels 111 are arranged in sequence. The areas on opposite sides of the first channel 111 and the third channel 111 are set as scattered item storage lanes 121, while the area between the first channel 111 and the third channel 111 is set as two batch item storage lanes 122 with the second channel 111 as the dividing channel.
[0096] like Figure 6 A schematic diagram of a multi-channel planar warehouse layout obtained by applying the planar warehouse layout method provided by the present invention is shown;
[0097] When there are three or more channels 111, the channels 111 are arranged sequentially. The area on the side opposite to the other channels 111 is set as a loose goods storage lane 121. Then, starting from the side opposite to the first channel 111 and the second channel 111, the goods storage lanes are arranged sequentially with each channel 111 as the boundary, in the following manner: one bulk goods storage lane 122, one loose goods storage lane 121, another loose goods storage lane 121, and another bulk goods storage lane 122. Among them, two adjacent loose goods storage lanes 121 are not divided but are combined into a double row of loose goods storage lanes.
[0098] Along the direction of each passageway 111, rows of platform panels and / or rows of shelves are respectively installed in each aisle 121 for scattered goods and in each aisle 122 for bulk goods, wherein:
[0099] The independent or wall-mounted aisle for storing scattered items shall be arranged with 1 to 3 rows of platform panels and / or shelves. The interior of two adjacent aisles that have been merged into one double-row aisle for storing scattered items shall be arranged with no more than 4 rows of platform panels and / or shelves. The number of storage units in each aisle for storing scattered items shall not exceed 1 / 3 of the number of storage units in the aisle for storing bulk items.
[0100] From the above description, it can be seen that:
[0101] First, the layout method of a flat warehouse provided in this embodiment is to divide at least one item storage block in an existing flat warehouse within its usable actual storage area and storage area, and to set up a passage in this item storage block, and to set up item storage aisles on both sides of the passage as a platform and / or shelf placement area.
[0102] in:
[0103] When there is only one passageway, one side of the passageway is set up as a storage lane for scattered items, and the other side is set up as a storage lane for bulk items.
[0104] When there are two channels, the area between the two channels is set as a bulk goods storage lane, and the opposite sides of each channel are set as loose goods storage lanes.
[0105] When there are three channels, the first and third channels are respectively set up as scattered item storage lanes on their opposite sides, and the area between the first and third channels is set up as two batch item storage lanes with the second channel as the dividing channel.
[0106] When there are three or more passages, the side of the first passage facing away from other passages is set as a storage lane for loose items. Starting from the side of the first passage and the second passage facing each other, the passages are arranged in sequence as follows: one storage lane for bulk items, one storage lane for loose items, another storage lane for loose items, and another storage lane for bulk items. This results in a warehouse layout with an asymmetrical layout of storage lanes with different storage numbers.
[0107] Arrange 1 to 3 rows of platform panels and / or shelves in the aisles for scattered items that are set up independently or against the wall, and the number of storage units in each aisle for scattered items shall not exceed 1 / 3 of the number of storage units in the aisle for bulk items, so as to flexibly cope with the storage of various bulk items.
[0108] Secondly, the layout method of the flat warehouse provided in this embodiment makes full use of the resources of the existing flat warehouse. Through innovative layout, it can adapt to complex inventory scenarios with multiple varieties, multiple batches, and uncertain batches or quantities of items. It improves the volume ratio of the flat warehouse and the efficiency of item storage and retrieval, reduces storage costs and warehouse management costs, thereby improving the economic benefits of the warehouse.
[0109] Proof of actual use:
[0110] The asymmetrical warehouse layout obtained by adopting the planar warehouse layout method provided in this embodiment can adapt to the storage of different batches of goods due to the asymmetrical distribution of storage aisles on both sides of the passage. This can reduce the honeycomb effect, increase the volume ratio, and accommodate the storage of multiple types of goods. Compared with the existing single-row planar warehouse layout, its volume ratio can be doubled from the usual 30-35% to 60-70%. If the stored goods are stacked in double layers, its volume ratio can be doubled.
[0111] Furthermore, due to the layout method of the planar warehouse provided in this embodiment, each item storage block has at least one passage, and different item storage aisles correspond to corresponding passages. Items can be stored and retrieved from the passages. Therefore, different items can be stored accordingly, and loading and unloading are extremely convenient.
[0112] Furthermore, in one alternative implementation:
[0113] The width of the passage 111 can be set to accommodate one or more of the following transport vehicles used in the flat warehouse when transporting items into and out of the item storage block 100: forklifts, pallet trucks, AGVs, shuttles, etc.
[0114] Furthermore, in one alternative layout method for a planar warehouse, the following may also be included:
[0115] Separator 112;
[0116] The dividing channel 112 is set in the loose goods storage lane 121 and / or the bulk goods storage lane 122, and the loose goods storage lane 121 and / or the bulk goods storage lane 122 are divided into two or more loose goods storage units and / or bulk goods storage units by the dividing channel 112.
[0117] Furthermore, in an alternative embodiment, the partition 112 is perpendicular to the passage 111, and the width of the partition 112 is sufficient to accommodate one-way passage of forklifts or pallet trucks, or AGVs, shuttles, or other transport vehicles used in the flat warehouse when transporting goods into and out of the scattered goods storage unit and / or the bulk goods storage unit.
[0118] Furthermore, such as Figure 7 The schematic diagram of the shelving and stacking structure used in the layout method of a planar warehouse provided by the present invention shows that, in an optional embodiment, the shelving 132 used may be mainly a single-layer shelving.
[0119] Furthermore, multiple single-layer shelves are connected longitudinally to form a single-layer continuous longitudinal shelf.
[0120] Furthermore, the single-layer continuous longitudinal rack consists of two beams fixedly installed side by side on the floor of the flat warehouse, and the two adjacent beams of the multiple parallel single-layer continuous longitudinal racks are connected and fixed to each other by connecting members 133.
[0121] Fixed single-layer shelving is used in flat warehouses. On the one hand, it can avoid storing inventory directly on the ground, thus avoiding potential storage risks such as insect infestation, water immersion and dampness. On the other hand, fixed shelving is sturdy and reliable, and occupies little space, which can improve the warehouse's volume ratio.
[0122] Furthermore, in an alternative embodiment, after the platform 131 or cargo packaging boxes are placed on top of the single-layer continuous longitudinal rack, its bottom has the height and space to allow an empty AGV trolley 141 or shuttle to pass freely.
[0123] The bottom of the platform and / or shelf is designed to allow empty AGVs to pass freely, making full use of warehouse space. When AGVs are used for automated loading and unloading in the warehouse, empty AGVs can pass under the platform and / or shelf, forming a one-way passage pattern within the storage area, thereby avoiding congestion and blockage in the aisles and improving throughput and transfer efficiency.
[0124] Furthermore, in the layout method of the planar warehouse provided in this embodiment:
[0125] Storage aisles for loose items and storage aisles for bulk items can be dynamically managed using a warehouse management system (WMS).
[0126] The warehouse management system (not shown in the diagram) allocates incoming loose items to the loose item storage aisle 121 for storage, and allocates incoming bulk items to the bulk item storage aisle 122 for storage; and
[0127] The warehouse management system performs real-time statistical analysis on the existing items in aisle 121 for loose items and aisle 122 for bulk items. After some bulk items were shipped out, the remaining loose inventory items in aisle 122 for bulk items are redistributed and reorganized.
[0128] The warehouse management system locates the scattered inventory items in aisle 121 and allocates the scattered inventory items in aisle 122 to aisle 121, issuing a transfer instruction; and
[0129] During off-peak hours when goods are moving in and out of the warehouse, the handling and sorting of any remaining loose inventory items is carried out.
[0130] Using a WMS system for management can further enhance the management capabilities of the flat warehouse layout method provided in this embodiment. Through the WMS system, items entering and leaving the flat warehouse are automatically allocated to storage locations within aisles for scattered items, bulk items, and large-volume items, based on their batch size. For example:
[0131] Products of the same batch number will be preferentially allocated to the same storage location within the same aisle, wherein:
[0132] For items entering the warehouse in batches that exceed 60% of the number of storage spaces in storage aisle 122, priority will be given to allocating them to storage space 122 to reduce the occupancy of storage spaces and maximize the number of products that can be stored in the warehouse.
[0133] For identical items that are stored in batches between the scattered items storage aisle and the batch items storage aisle, the remaining storage space in the batch items storage aisle 122 will be searched first for storage. If there are no remaining storage spaces that meet the conditions, they will be allocated to the batch items storage aisle for storage.
[0134] As for miscellaneous items, they are mainly stored in the scattered items storage aisles for easy access.
[0135] In addition, if the remaining quantity of goods after they are taken out of the warehouse is less than or equal to the number of scattered goods storage locations in the aisle, the WMS system will automatically adjust the storage location of the inventory items and issue a transfer instruction to reorganize and adjust them during the off-peak hours of the warehouse.
[0136] Further:
[0137] If an AGV trolley 141 is already installed in the flat warehouse, the transfer instruction can be executed by the AGV trolley. Specifically, the AGV trolley 141 moves the scattered items in the bulk item storage aisle 122 to the storage location in the scattered item storage aisle 121 according to the transfer instruction issued by the WMS system.
[0138] Typically, for aisles with two rows of platform panels and / or shelves, 2 to 3 spare storage spaces should be reserved to facilitate the movement and reorganization of the storage space when retrieving items from the inner row of two rows of different products.
[0139] By combining AGV vehicles and managing the layout method of the flat warehouse provided in this embodiment through a WMS system, the effectiveness of warehouse capacity can be maintained in real time, reducing the honeycomb effect that often occurs in traditional densely laid-out flat warehouses, thereby improving the availability of warehouse capacity in real time. Actual use has proven that with this management, the availability of warehouse locations can reach over 98%.
[0140] In conclusion, it can be seen that:
[0141] The layout method for a flat warehouse provided by this invention can flexibly cope with the storage of different batches of goods through the asymmetrical layout of storage locations. Its layout design is novel and unique, the technical solution provided is simple and practical, and it can effectively improve the volume ratio and the efficiency of goods storage and retrieval in flat warehouses.
