Description

Technical Field

[0001] This invention relates to the field of warehouse management technology, specifically to a material inbound and outbound management system and method. Background Technology

[0002] In warehouse logistics management, in order to improve space utilization, the actual operation site usually uses one or more intersecting conveyor belts to carry multiple categories and batches of materials for alternating flow.

[0003] When multiple different types of materials (such as materials of different specifications or with different shelf lives) are processed sequentially or simultaneously on the same conveyor belt route, their transport routes often overlap. Existing systems mostly rely on manual or semi-automatic initial sorting at the beginning of the conveyor belt. Once the materials enter the main conveyor line, their subsequent flow can only be controlled by fixed mechanical guiding devices or a pre-set single logical path, lacking real-time adjustments to the transport route based on the current state of the materials.

[0004] Therefore, the following problems may occur in actual operations: before the sorting of the first type of materials is completed, the second type of materials are pushed into the same transportation route, resulting in the accumulation of the two types of materials in the handover area or stacking area. Manual sorting is then carried out in the handover area or stacking area, which disrupts the order of entering and leaving the warehouse and increases time costs and error rates. Summary of the Invention

[0005] The purpose of this invention is to provide a material inbound and outbound management system and method. The technical problem to be solved is how to realize real-time category verification and dynamic adjustment of transportation routes during the process of multiple categories of materials sharing a conveyor belt for alternating inbound and outbound operations, so as to solve the problem of chaotic material transportation.

[0006] This invention is achieved through the following technical solution:

[0007] The first aspect provides a material inbound and outbound management system, including:

[0008] The route creation module is used to obtain the route distribution map of the warehouse and create a route topology map based on the route distribution map. The root node of the route topology map is the storage area for storing materials, the child nodes are the intersection areas of two transportation routes, and the end node is the stacking area for stacking materials. The edges of the route topology map are the transportation routes for materials in the warehouse. Each of the above transportation routes is used to transport materials marked with one or more categories.

[0009] The aforementioned transportation route is equipped with an information collection module for collecting material information and a marking module for classifying materials; the marking module is connected to the information collection module, and the marking module classifies and marks the materials based on the material information to obtain category markings;

[0010] An identification and verification module is installed in the aforementioned handover area to identify and verify category markings, and the aforementioned identification and verification module is connected to the information collection module;

[0011] The aforementioned handover area is also equipped with a push module that connects the identification and verification module and the route creation module. The push module adjusts the transportation route of the materials based on the verified category tags.

[0012] The route creation module described above transforms the warehouse route distribution into a route topology map, clarifying the hierarchical relationship between storage areas, handover areas, and stacking areas, making each transportation route a logical unit that can be independently managed and scheduled.

[0013] The aforementioned information collection module and tagging module work together to assign a "category tag" to each transported material in real time, ensuring that the system can track the category of the material without relying on manual memory or initial one-time sorting judgment.

[0014] By deploying an identification and verification module in the aforementioned handover area, the system no longer passively relies on the sorting results at the starting point. This module can proactively and in real-time read and verify the category markings of materials. The intelligent checkpoints set up in the handover area solve the inherent defect of existing technologies that cannot intervene once the materials enter the main line.

[0015] The aforementioned push module adjusts the transportation route of materials based on the verification results of the identification and verification module, and performs multi-path selection based on the current status of the materials. This allows the system to flexibly determine the subsequent flow of materials in the handover area according to their actual category and current verification status, thereby effectively preventing disorderly accumulation of different categories of materials in the handover and stacking areas due to chaotic transportation routes.

[0016] Furthermore, the aforementioned identification and verification module includes a marker detection unit, a template storage unit, and a comparison unit;

[0017] The aforementioned marking and detection unit is used to collect the category markings of materials within the handover area to obtain the actual markings;

[0018] The aforementioned template storage unit stores a list of associations between material information and category tags;

[0019] The aforementioned comparison unit connects the marker detection unit, the information acquisition module, and the template storage unit;

[0020] The comparison unit is used to call the category tag associated with the material information in the template storage unit after receiving the material information sent by the information acquisition module, obtain the benchmark tag, compare the benchmark tag with the actual tag, and generate a verification pass instruction if the benchmark tag and the actual tag are consistent; otherwise, generate a re-tag instruction.

[0021] On the one hand, the actual markings of materials in the handover area are collected in real time by the aforementioned marking detection unit; on the other hand, the baseline markings of the materials registered in the system are retrieved by the aforementioned template storage unit and information collection module. By comparing the actual markings with the baseline markings, the accuracy and reliability of category marking verification are improved, and misjudgments caused by initial marking errors are reduced.

[0022] The aforementioned comparison unit automatically executes the comparison logic and generates verification pass instructions or remark instructions in real time, enabling real-time verification on the high-speed conveyor belt without the need for manual checking in the handover area, thus improving processing efficiency and avoiding time delays and error rates caused by manual intervention.

[0023] For those that fail verification, a re-marking instruction is generated, enabling the system not only to detect problems but also to automatically trigger the correction process and clarify the correction route in abnormal states.

[0024] Furthermore, the aforementioned transportation route consists of several first conveyor belts. The aforementioned information collection module, marking module, and identification verification module are sequentially arranged on one or more first conveyor belts according to the transportation direction. The one or more first conveyor belts equipped with the aforementioned information collection module, marking module, and identification verification module constitute a conveyor belt group. Several second conveyor belts are set at both ends of the conveyor belt group. The aforementioned second conveyor belts and the conveyor belt group enclose and form a loop route.

[0025] The aforementioned information collection module, marking module, and identification verification module are centrally deployed on a conveyor belt group consisting of several first conveyor belts, forming a centralized processing hub. This ensures that all materials undergo standardized processing procedures before entering the complex branch route network, guaranteeing comprehensive coverage of the verification process.

[0026] The second conveyor belt and the conveyor belt group form a loop route, creating an independent "correction buffer" for materials that fail verification, without interrupting the main process or interfering with other materials. Materials marked as abnormal can be re-marked and verified within the loop route until verification is successful. The entire marking, verification, and correction process is completed in a closed loop within the system, ensuring that abnormal markings are resolved while maintaining the continuous and smooth operation of the main line transportation.

[0027] Furthermore, upon receiving the re-marking instruction, the aforementioned push module pushes the materials to the circulation route.

[0028] When the material marking verification fails, it is pushed to the loop route to prevent the incorrectly categorized material from entering the subsequent handover area or stacking area. This avoids the risk of abnormally marked material continuing to travel incorrectly in the complex road network, thereby causing a wider range of chaos and limiting the impact of the error to the loop processing area.

[0029] Materials marked with abnormalities are diverted to the circulation route, ensuring that the normal flow of materials on the first conveyor belt is not affected by their reprocessing, thus guaranteeing the overall throughput of the system and preventing the entire transportation line from being blocked or stopped due to individual materials.

[0030] Furthermore, after receiving the verification pass instruction, the aforementioned push module obtains the actual marker collected by the identification verification module, and pushes the materials to the corresponding transportation route based on the actual marker.

[0031] The final destination of the aforementioned materials in the handover area is not predetermined, but dynamically determined by the actual "verification passed" marker at that moment. This enables the system to handle complex scenarios where multiple types of materials appear alternately and transportation routes overlap, ensuring that each item is accurately directed to its corresponding stacking area or the next level of transportation route.

[0032] By using verified actual tags as the basis for push notifications, the final verification and binding of category tags and material information at the decision point is achieved, which solves the problem of materials entering the wrong storage location due to misclassification of transportation routes and reduces the error rate.

[0033] The second aspect provides a method for managing the entry and exit of materials, including the following steps:

[0034] S1. Obtain the route distribution map of the warehouse, and create a route topology map based on the route distribution map; wherein, the root node of the route topology map is the storage area for storing materials, the child node is the intersection area of ​​two transportation routes, the end node is the stacking area for stacking materials, and the edge of the route topology map is the transportation route of materials in the warehouse; each of the above transportation routes is used to transport materials marked with one or more categories.

[0035] S2. Collect material information along the above transportation route; classify and label the materials based on the above material information to obtain category labels;

[0036] S3. Identify and verify the correctness of the category markings of the materials in the aforementioned handover area;

[0037] S4. If the category label of the above-mentioned materials is correct, then based on the category label, push the materials to the corresponding transportation route.

[0038] S5. If the category label of the above materials is incorrect, the materials shall be reclassified and labeled, and the process shall return to S3 to continue.

[0039] Furthermore, in the aforementioned handover area, the identification and verification of the correctness of the category markings of the goods includes the following steps:

[0040] Collect the category markings of the materials in the above-mentioned handover area to obtain the actual markings;

[0041] After receiving the above material information, retrieve the category tag associated with the material information from the association list of material information and category tag to obtain the benchmark tag;

[0042] Compare the above benchmark marks with the actual marks;

[0043] If the above benchmark mark matches the actual mark, a verification pass instruction is generated;

[0044] If the above reference mark and the actual mark are inconsistent, a remarking instruction will be generated.

[0045] Furthermore, upon receiving the aforementioned remarking instruction, the materials are pushed to the loop route; the loop route includes a conveyor belt group consisting of one or more first conveyor belts equipped with an information collection module, a marking module, and an identification verification module, as well as several second conveyor belts, the second conveyor belts being located at both ends of the conveyor belt group, and the second conveyor belts and the conveyor belt group forming a loop route.

[0046] Furthermore, upon receiving the verification pass instruction, the actual marker is acquired, and the supplies are pushed to the corresponding transportation route based on the actual marker.

[0047] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0048] The route creation module described above transforms the warehouse route distribution into a route topology map, clarifying the hierarchical relationship between storage areas, handover areas, and stacking areas, making each transportation route a logical unit that can be independently managed and scheduled.

[0049] The aforementioned information collection module and tagging module work together to assign a "category tag" to each transported material in real time, ensuring that the system can track the category of the material without relying on manual memory or initial one-time sorting judgment.

[0050] By deploying an identification and verification module in the aforementioned handover area, the system no longer passively relies on the sorting results at the starting point. This module can proactively and in real-time read and verify the category markings of materials. The intelligent checkpoints set up in the handover area solve the inherent defect of existing technologies that cannot intervene once the materials enter the main line.

[0051] The aforementioned push module adjusts the transportation route of materials based on the verification results of the identification and verification module, and performs multi-path selection based on the current status of the materials. This allows the system to flexibly determine the subsequent flow of materials in the handover area according to their actual category and current verification status, thereby effectively preventing disorderly accumulation of different categories of materials in the handover and stacking areas due to chaotic transportation routes.

[0059] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0060] First embodiment:

[0061] A material inbound and outbound management system, combined with Figure 1 ,include:

[0062] Route creation module 1 is used to obtain the route distribution map of the warehouse and create a route topology map based on the route distribution map. The root node of the route topology map is the storage area for storing materials, the child nodes are the intersection areas of two transportation routes, and the end node is the stacking area for stacking materials. The edges of the route topology map are the transportation routes for materials in the warehouse. Each of the above transportation routes is used to transport materials marked with one or more categories.

[0063] The aforementioned transportation route is equipped with an information collection module 2 for collecting material information and a marking module 3 for classifying materials. The marking module 3 is connected to the information collection module 2, and the marking module 3 classifies and marks the materials based on the material information to obtain category markings. The material information includes the shelf life and the name of the material. The category markings include the near-expiration status and the name of the material.

[0064] An identification and verification module 4 is installed in the aforementioned handover area to identify and verify category markings. The identification and verification module 4 is connected to the information collection module 2.

[0065] In the aforementioned handover area, a push module 5 is also installed, which connects the identification and verification module 4 and the route creation module 1. The push module 5 adjusts the transportation route of the materials based on the verified category markers.

[0066] The route creation module 1 described above transforms the warehouse route distribution into a route topology map, clarifying the hierarchical relationship between the storage area, handover area, and stacking area, so that each transportation route becomes a logical unit that can be independently managed and scheduled.

[0067] The aforementioned information collection module 2 and marking module 3 work together to ensure that each transported material can be assigned a "category mark" in real time, ensuring that the system can track the category of the material without relying on manual memory or initial one-time sorting judgment.

[0068] By deploying identification and verification module 4 in the aforementioned handover area, the system no longer passively relies on the sorting results at the starting point. This identification and verification module 4 can actively and in real time read and verify the category markings of materials. By setting up intelligent checkpoints in the handover area, it solves the inherent defect of existing technologies that cannot intervene once the materials enter the main line.

[0069] The aforementioned push module 5 adjusts the transportation route of the materials based on the verification results of the identification and verification module 4, and performs multi-path selection based on the current status of the materials. This allows the system to flexibly determine the subsequent flow of the materials in the handover area according to their actual category and current verification status, thereby effectively preventing the disorderly accumulation of different categories of materials in the handover and stacking areas due to chaotic transportation routes.

[0070] One possible use case is a warehouse with multiple stacking areas, storage areas, and handover areas, combined with... Figure 2 and Figure 3The warehouse has 2 stacking areas, 6 storage areas, and 6 transfer areas. The lines connecting adjacent transfer areas form a transportation route. Each transfer area can be equipped with a push module 5 to facilitate changes in the transportation route of materials. Upon arrival, two types of materials are simultaneously placed into the transportation route from stacking areas 1 and 2. Materials from stacking area 1 travel along the transportation route to transfer areas 1 and 2 sequentially, while materials from stacking area 2 travel along the transportation route to transfer area 2. The materials then continue to the next transportation route. During this movement, material information is collected and category markings are applied. The materials then arrive at transfer area 3, where the markings are verified. If the markings are correct, the verification passes, and the materials are pushed onto the corresponding transportation route based on the actual markings, transported to any of the 1-6 storage areas. If the markings are incorrect, the verification fails, and the materials are pushed onto the loop route, returning to transfer area 2 for reprocessing. Similarly, when goods are shipped out, two types of goods can be put into storage areas, such as storage areas 1 and 3, into the transportation route. Goods from storage area 1 arrive at transfer areas 4 and 3 in sequence via the transportation route, and goods from storage area 3 arrive at transfer areas 5 and 3 in sequence via the transportation route. Then the goods continue to move to the next transportation route. During the movement, the goods information is collected and the category is marked. Then the goods arrive at transfer area 2, where the marking is verified. If the marking is correct, the verification is passed, and the goods are pushed to the corresponding transportation route based on the actual marking, and transported to stacking area 1 or stacking area 2. If the marking is incorrect, the verification fails, and the goods are pushed to the loop route and returned to transfer area 3 for reprocessing.

[0071] Second embodiment:

[0072] Based on the first embodiment, the above-mentioned identification and verification module 4 includes a marker detection unit 41, a template storage unit 42, and a comparison unit 43;

[0073] The aforementioned marking detection unit 41 is used to collect the category markings of materials in the handover area to obtain the actual markings;

[0074] The template storage unit 42 above stores a list of associations between material information and category tags;

[0075] The comparison unit 43 mentioned above is connected to the mark detection unit 41, the information acquisition module 2 and the template storage unit 42;

[0076] The comparison unit 43 is used to call the category tag associated with the material information in the template storage unit 42 after receiving the material information sent by the information acquisition module 2, obtain the benchmark tag, compare the benchmark tag with the actual tag, and generate a verification pass instruction if the benchmark tag and the actual tag are consistent; otherwise, generate a re-tag instruction.

[0077] On the one hand, the actual markings of materials in the handover area are collected in real time by the aforementioned marking detection unit 41; on the other hand, the baseline markings of the materials registered in the system are retrieved by the aforementioned template storage unit 42 and information collection module 2. By comparing the actual markings with the baseline markings, the accuracy and reliability of category marking verification are improved, and misjudgments caused by initial marking errors are reduced.

[0078] The comparison unit 43 automatically executes the comparison logic and generates a verification pass instruction or a remark instruction in real time, enabling real-time verification on the high-speed conveyor belt without the need for manual checking in the handover area, thus improving processing efficiency and avoiding time delays and error rates caused by manual intervention.

[0079] For those that fail verification, a re-marking instruction is generated, enabling the system not only to detect problems but also to automatically trigger the correction process and clarify the correction route in abnormal states.

[0080] Third embodiment:

[0081] Based on any of the above embodiments, combined with Figure 2 and Figure 3 The aforementioned transportation route consists of several first conveyor belts. The aforementioned information collection module 2, marking module 3, and identification verification module 4 are sequentially arranged on one or more first conveyor belts according to the transportation direction. The one or more first conveyor belts with the aforementioned information collection module 2, marking module 3, and identification verification module 4 constitute a conveyor belt group 6. Several second conveyor belts 7 are provided at both ends of the conveyor belt group 6. The aforementioned second conveyor belts 7 and the conveyor belt group 6 enclose each other to form a loop route.

[0082] The aforementioned information collection module 2, marking module 3, and identification verification module 4 are centrally deployed on a conveyor belt group 6 consisting of several first conveyor belts, forming a centralized processing hub. This ensures that all materials undergo standardized processing procedures before entering the complex branch route network, guaranteeing comprehensive coverage of the verification process.

[0083] The second conveyor belt 7 and the conveyor belt group 6 form a loop route, creating an independent "correction buffer" for materials that fail verification without interrupting the main process or interfering with other materials. Materials marked as abnormal can be re-marked and verified within the loop route until verification is successful. The entire marking, verification, and correction process is completed in a closed loop within the system, ensuring that abnormal markings are resolved while maintaining the continuous and smooth operation of the main line transportation.

[0084] Fourth embodiment:

[0085] Based on the third embodiment, the aforementioned push module 5 pushes the materials to the circulation route after receiving the re-marking instruction.

[0086] When the material marking verification fails, it is pushed to the loop route to prevent the incorrectly categorized material from entering the subsequent handover area or stacking area. This avoids the risk of abnormally marked material continuing to travel incorrectly in the complex road network, thereby causing a wider range of chaos and limiting the impact of the error to the loop processing area.

[0087] Materials marked with abnormalities are diverted to the circulation route, ensuring that the normal flow of materials on the first conveyor belt is not affected by their reprocessing, thus guaranteeing the overall throughput of the system and preventing the entire transportation line from being blocked or stopped due to individual materials.

[0088] In a specific embodiment, after receiving the verification pass instruction, the push module 5 obtains the actual marker collected by the identification verification module 4, and pushes the materials to the corresponding transportation route based on the actual marker.

[0089] The final destination of the aforementioned materials in the handover area is not predetermined, but dynamically determined by the actual "verification passed" marker at that moment. This enables the system to handle complex scenarios where multiple types of materials appear alternately and transportation routes overlap, ensuring that each item is accurately directed to its corresponding stacking area or the next level of transportation route.

[0090] By using verified actual tags as the basis for push notifications, the final verification and binding of category tags and material information at the decision point is achieved, which solves the problem of materials entering the wrong storage location due to misclassification of transportation routes and reduces the error rate.

[0097] S5. If the category label of the above materials is incorrect, the materials shall be reclassified and labeled, and the process shall return to S3 to continue.

[0100] Collect the category markings of the materials in the above-mentioned handover area to obtain the actual markings;

[0101] After receiving the above material information, retrieve the category tag associated with the material information from the association list of material information and category tag to obtain the benchmark tag;
