Description

Technical Field

[0001] This invention relates to the field of material storage technology, and in particular to a ton-bag inbound / outbound system and method. Background Technology

[0002] After each production process is completed, the anode material factory needs to transfer the produced materials to the corresponding warehouses for storage. Since these materials are typically stacked in tonnes on the warehouse floor, and different areas within the warehouse store various types of products, warehouse management is highly complex. Currently, the statistical work during product inbound and outbound processes relies mainly on manual operation, significantly increasing the workload of warehouse personnel. This not only leads to a substantial decrease in work efficiency and a prolonged material inbound and outbound cycle, but also results in a significant increase in the statistical error rate due to the highly repetitive and intensive nature of the operations. The resulting problems of inaccurate data and information lag further cause numerous inconveniences for workshop personnel during the material requisition process, affecting the smooth execution of production plans. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a ton-bag inbound / outbound system and method, enabling automated warehouse management of ton-bags.

[0004] In order to achieve the objective of this invention, the following solution is proposed: A ton-bag inbound / outbound system, comprising a shelving system and a control system.

[0005] The shelving system consists of, in sequence, a package delivery conveyor line, an inbound lifting platform, M inbound conveyor lines, shelving, M outbound conveyor lines, an outbound lifting platform, and an outbound package delivery conveyor line. The package delivery and outbound conveyor lines are equipped with inbound and outbound scanning devices, respectively, used to scan the labels on the ton bags and obtain material information, including product name, batch number, and weight. The shelving system comprises M storage layers, each layer containing N rows of storage lines, and each row containing n sequentially connected ton bag delivery conveyor lines. Each ton bag delivery conveyor line stores t ton bags. M, N, and t are all positive integers, and n is a positive integer greater than 1. The inbound delivery conveyor line is located at the beginning of all storage lines in the corresponding storage layer; the outbound delivery conveyor line is located at the end of all storage lines in the corresponding storage layer. The control system includes a network switch, an embedded engineering computer, a CAN bus, and multiple first camera modules distributed within the shelving. The embedded engineering computer is connected to the network switch, the CAN bus, and the multiple first camera modules. The CAN bus is connected to the scanning inbound device, the scanning outbound device, and the power equipment of all conveyor lines. The first camera modules are used to acquire images of the (n-1)th and nth ton-bag conveyor lines in the corresponding storage line, and send the information of the number of ton-bags 'a' on the (n-1)th ton-bag conveyor line and the number of ton-bags 'b' on the nth ton-bag conveyor line to the embedded engineering computer, respectively. The embedded engineering computer includes a setting module, a storage module, a first calculation module, a path planning module, and a second calculation module. The setting module is used to pre-set the names of the materials to be stored in each row of storage lines; the storage module is used to store material information; the first calculation module is used to calculate the quantity of ton bags and the total weight of ton bags corresponding to different materials in the shelf; the second calculation module is used to calculate whether a is less than t and whether b is less than t. If a is less than t, a "yes" signal is sent to the path planning module; if a equals t and b is less than t, a "no" signal is sent to the path planning module; if a equals t and b equals t, a "full" signal is sent to the path planning module; the path planning module is used to select a row of storage lines according to the names in the material information and determine different inbound paths according to the "yes," "no," or "full" signals; the embedded engineering computer is used to send the inbound paths to the shelf system.

[0006] Furthermore, for the selected storage line, if the path planning module receives a "yes" signal, the inbound path includes signals to operate the 1st to n-1th ton bag conveyor lines; if the path planning module receives a "no" signal, the inbound path includes signals to operate the 1st to nth ton bag conveyor lines; if the path planning module receives a "full" signal, another row of storage lines is selected.

[0007] Furthermore, each ton bag conveyor line is equipped with a weighing device to weigh the total weight of the materials on the corresponding ton bag conveyor line. A CAN bus connects all the weighing devices on all ton bag conveyor lines, and the weighing devices are also used to record the total weight of their respective materials, T1~T. n T is sent to the embedded engineering computer via the CAN bus. n Let T be the total weight of the materials on the nth ton bag conveyor line; the embedded engineering computer also includes a third calculation module. After the path planning module selects a row of storage lines, the third calculation module is used to calculate the weight of the materials on the T ton bag conveyor line. n The numbers are sequentially accumulated up to T1, and it is determined whether the accumulated value is greater than the required outbound weight each time. The process stops when the accumulated value first exceeds the required outbound weight. The number of accumulations is equal to the number of ton bag conveyor lines that need to be run. The third calculation module is used to send the accumulation count signal to the path planning module, which is used to determine the corresponding outbound path.

[0008] Furthermore, for a selected row of storage lines, if the value accumulated by the third calculation module to T1 is still less than the required outbound weight, the route planning module will select another row of storage lines, and the third calculation module will continue to accumulate.

[0009] Furthermore, the control system also includes a display connected to the CAN bus, which displays the total number of tonnes corresponding to different materials on the shelf, the total weight of the tonnes, and the remaining number of tonnes that can be stored.

[0010] Furthermore, the control system also includes multiple second camera modules distributed along the ton bag conveying path. Each of the multiple second camera modules is connected to an embedded engineering computer. The second camera modules are used to capture images of the ton bags. If the ton bag gets stuck during the conveying process, the second camera modules are used to send the information about the stuck ton bag to the embedded engineering computer.

[0011] Furthermore, each conveyor line uses roller conveyors.

[0012] A method for handling the inbound and outbound of ton bags, using the aforementioned ton bag inbound and outbound system, includes the following steps: S100, Warehousing Stage: S101. Pre-set the names of materials to be stored in each row of storage lines on the embedded engineering computer; S102. Click the "Inbound" button. The embedded engineering computer sends the inbound signal to the bag delivery conveyor line via the CAN bus. The bag delivery conveyor line starts running and first transports the ton bag to the scanning inbound device. The scanning inbound device scans the ton bag and sends the obtained material information to the embedded engineering computer via the CAN bus. The ton bag is then transported to the inbound lifting platform. S103. After receiving the material information, the embedded engineering computer stores the material information in the storage module; the first calculation module accumulates the quantity and total weight of the ton bags corresponding to the material based on the product name; the path planning module selects a storage line based on the product name; the second calculation module calculates and sends a "yes" or "no" or "full" signal for the storage line to the path planning module; the path planning module determines the inbound path; the embedded engineering computer sends the inbound path signal to the inbound lifting platform, the inbound conveyor line corresponding to the selected storage line, and the selected ton bag conveyor line in the selected storage line via the CAN bus; S104. The inbound lifting platform lifts the ton bags to the corresponding inbound conveyor line; the inbound conveyor line transports the ton bags to the selected storage line; the selected ton bag conveyor line in the storage line starts operating, completing the inbound process.

[0013] S200, Outbound Stage: S201. Click the "Outbound" button and enter the outbound information into the embedded engineering computer by scanning the QR code on the process sheet. The outbound information includes the product name and outbound weight (T). 出 The storage module saves outbound information; S202, The path planning module selects a storage line based on the product name. Within this storage line, all weighing equipment begins weighing and records the total material weight T1~T. nThe signal is sent to the third calculation module; the third calculation module sends the accumulated count signal to the path planning module; the path planning module determines the corresponding outbound path; the embedded engineering computer sends the outbound path signal to the selected ton bag conveyor line, the corresponding outbound conveyor line, the outbound lifting platform, and the outbound conveyor line in the selected storage line via the CAN bus. S203, the ton bag conveyor line transports the ton bags to the corresponding outbound conveyor line; the outbound conveyor line transports the ton bags to the outbound lifting platform; the outbound lifting platform lowers the ton bags onto the outbound conveyor line; the outbound conveyor line transports the ton bags to the scanning outbound equipment; the scanning outbound equipment scans the ton bag's label and obtains the material information, then sends the material information to the embedded engineering computer via the CAN bus. The first calculation module subtracts the quantity of ton bags corresponding to the material and the total weight of the ton bags based on the product name.

[0014] Furthermore, in step S203, after the scanning and outbound equipment scans a ton bag, the ton bag conveyor line starts conveying the next ton bag; when the cumulative material weight subtracted by the first calculation module in this outbound task is greater than the outbound weight for the first time, the outbound process is completed.

[0015] The beneficial effects of this invention are as follows: 1. Greatly improves the efficiency and speed of inbound and outbound operations: Automatically identifies material labels and completes information collection in seconds, replacing the tedious processes of traditional manual counting, recording, and verification.

[0016] 2. Achieve accurate and real-time inventory data: Automated data collection fundamentally avoids manual copying, input errors, and delays caused by forgetting; every inbound and outbound operation updates the inventory management system in real time and automatically, ensuring that the system inventory data and physical inventory always remain highly consistent, providing an accurate data foundation for management decisions.

[0017] 3. Significantly reduce labor intensity and costs: Freeing warehouse staff from repetitive, heavy, and error-prone manual statistical work, allowing them to focus on higher-value management tasks such as inventory optimization, inspection, and anomaly handling. This not only reduces labor costs but also improves employee job satisfaction and sense of value.

[0018] 4. Enhanced Material Traceability and Warehouse Location Management: The system can accurately record information such as batch number, product name, warehousing time, and storage location for each ton of material. The system allows for quick location of the required materials, solving the problems of difficulty in finding and management chaos caused by mixing various materials.

[0019] 5. Seamless integration with the production planning system: Real-time and accurate inventory data can be synchronized to the upper management system in a timely manner. Workshop material requisition personnel can know the material inventory status in advance, and production planners can also dynamically adjust production scheduling based on the actual inventory, ensuring smooth material requisition in the production process and guaranteeing the efficient and smooth execution of the production plan.

[0020] 6. Improve warehouse space utilization and security: Through systematic warehouse location management and data guidance, the location of material stacking can be planned more rationally and compactly, reducing the waste of space and time caused by searching for materials; at the same time, it reduces human intervention and also reduces the safety risks that may be caused by improper operation.

[0022] Example 1 This embodiment provides a ton-bag inbound / outbound system, including a shelving system and a control system.

[0023] like Figure 1 , Figure 2 As shown, the shelving system sequentially includes a package delivery conveyor line, an inbound lifting platform, M inbound conveyor lines, shelving, M outbound conveyor lines, an outbound lifting platform, and an outbound conveyor line. The package delivery and outbound conveyor lines are equipped with inbound and outbound scanning devices, respectively, used to scan the labels on the ton bags and obtain material information, including product name, batch number, and weight. The shelving includes M storage layers, each storage layer includes N rows of storage lines, and each row of storage lines includes n ton bag conveyor lines connected end-to-end. Each ton bag conveyor line is used to store t ton bags, and each ton bag conveyor line has an independent power unit. M, N, and t are all positive integers, and n is a positive integer greater than 1. In this embodiment, M is 3, N is 3, and n is 4. The inbound conveyor line is located at the beginning of all storage lines in the corresponding storage layer; the outbound conveyor line is located at the end of all storage lines in the corresponding storage layer.

[0024] like Figure 3As shown, the control system includes a network switch, an embedded engineering computer, a CAN bus, multiple first camera modules, multiple second camera blocks, and a display. The embedded engineering computer is connected to the network switch, the CAN bus, the multiple first camera modules, and the multiple second camera blocks. The CAN bus is connected to the scanning inbound device, the scanning outbound device, the display, and the power equipment of all conveyor lines. All conveyor lines refer to the package delivery conveyor line, the inbound conveyor line, the outbound conveyor line, the package delivery conveyor line, and the ton bag conveyor line. Each conveyor line uses a roller conveyor.

[0025] Multiple first camera modules are distributed inside the shelf, or more precisely, at the end of the conveyor of each row of storage lines. They are used to collect images of the ton bags on the (n-1)th and nth ton bag conveyor lines of the corresponding storage lines, that is, the images of the ton bags on the 3rd and 4th ton bag conveyor lines. The information of the number of ton bags 'a' on the 3rd ton bag conveyor line and the number of ton bags 'b' on the 4th ton bag conveyor line are respectively sent to the embedded engineering computer.

[0026] The embedded engineering computer includes a setup module, a storage module, a first computing module, a path planning module, and a second computing module, as detailed below: The settings module is used to pre-set the names of the materials to be stored in each row of storage lines.

[0027] The storage module is used to save material information.

[0028] The first calculation module is used to calculate the quantity and total weight of ton bags corresponding to different materials on the shelf. During the receiving stage, the first calculation module is used to accumulate the quantity and total weight of ton bags corresponding to different materials on the shelf. During the outbound stage, the first calculation module is used to subtract the quantity and total weight of ton bags corresponding to the material.

[0029] The second calculation module is used to calculate whether a is less than t and whether b is less than t. If a is less than t, it sends a "yes" signal to the path planning module; if a is equal to t and b is less than t, it sends a "no" signal to the path planning module; if a is equal to t and b is equal to t, it sends a "full" signal to the path planning module.

[0030] The path planning module is used to select a row of storage lines based on the product name in the material information, and to determine different inbound routes based on the "yes", "no", or "full" signals. For the selected storage line, if the path planning module receives a "yes" signal, the inbound route includes signals to run the 1st to n-1th ton bag conveyor lines; if the path planning module receives a "no" signal, the inbound route includes signals to run the 1st to nth ton bag conveyor lines; if the path planning module receives a "full" signal, another row of storage lines is selected.

[0031] Embedded engineering computers are used to send the inbound path to the shelving system.

[0032] It should be noted that, for the selected storage line, if a is less than t, it means that the (n-1)th ton bag conveyor line is not yet full of ton bags, and there are still empty spaces remaining (e.g., Figure 4 As shown in ①), the second calculation module sends a "yes" signal to the path planning module. The inbound path contains signals to operate the 1st to (n-1th) ton bag conveyor lines; therefore, it is only necessary to synchronize the operation of the 1st to (n-1th) ton bag conveyor lines. During ton bag inbound, the inbound conveyor line transports the ton bag to the selected storage line, and then the pushing mechanism pushes the ton bag towards the storage line. Simultaneously, the 1st to (n-1th) ton bag conveyor lines operate synchronously, completing the inbound process (e.g., ...). Figure 4 (as shown in ②).

[0033] It should be noted that, for the selected storage line, if a equals t and b is less than t, it means that the first to (n-1)th ton bag conveyor lines are already full, and only the nth ton bag conveyor line is not yet full, with empty spaces remaining. Therefore, the second calculation module sends a "no" signal to the path planning module, and the inbound path includes signals to make the first to nth ton bag conveyor lines run. When ton bags are inbound, the inbound conveyor line transports the ton bags to the selected storage line. If b for the nth ton bag conveyor line is equal to 0, the pushing mechanism pushes the ton bags towards the storage line, while the first to nth ton bag conveyor lines run synchronously to complete the inbound process. If b for the nth ton bag conveyor line is not equal to 0, the nth ton bag conveyor line first runs in the direction of the inbound conveyor line (e.g., ...). Figure 5 As shown in ①), until the ton bags on its surface are concentrated towards the direction of the inbound conveyor line (such as...). Figure 5 (As shown in ②), then the pushing mechanism pushes the ton bags towards the storage line, while the 1st to nth ton bag conveyor lines move synchronously towards the outbound conveyor line to complete the warehousing (as shown in ②). Figure 5 (As shown in ③).

[0034] It should be noted that for the selected storage line, if a equals t and b equals t, it means that this storage line is already full of ton bags. Therefore, the second calculation module sends a "full" signal to the path planning module. The path planning module then selects another storage line. For the newly selected storage line, the second calculation module calculates again whether a is less than t and whether b is less than t, and then sends a "yes," "no," or "full" signal to the path planning module. The path planning module determines different inbound routes based on the "yes," "no," or "full" signal.

[0035] Embedded engineering computers can also be equipped with monitoring modules. If all storage lines are about to be full for materials of the same name, the monitoring module will issue an alarm to remind staff to add more storage lines.

[0036] The above solution details the functions of each module in the inbound process. For the outbound process, the modules involved are as follows: Each ton bag conveyor line is equipped with a weighing device, which is used to weigh the total weight of the materials on the corresponding ton bag conveyor line. A CAN bus connects all the weighing devices on all ton bag conveyor lines, and the weighing devices are also used to record the total weight of their respective materials, T1~T. n The data is transmitted via the CAN bus to the embedded engineering computer. T1 represents the total weight of the materials on the first ton bag conveyor line. n Let T be the total weight of the materials on the nth ton bag conveyor line; the embedded engineering computer also includes a third calculation module. During the outbound phase, after the path planning module selects a row of storage lines, the third calculation module is used to calculate the weight of the materials on the T ton bag conveyor line. n The numbers are sequentially accumulated up to T1, and it is determined whether the accumulated value is greater than the required outbound weight each time. The process stops when the accumulated value first exceeds the required outbound weight. The number of accumulations is equal to the number of ton bag conveyor lines that need to be run. The third calculation module is used to send the accumulation count signal to the path planning module, which is used to determine the corresponding outbound path.

[0037] It should be noted that for a selected row of storage lines, if the value accumulated by the third calculation module to T1 is still less than the required outbound weight, the route planning module will add another row of storage lines, and the third calculation module will continue to accumulate. Outbound shipments will be processed according to the order of the selected storage lines.

[0038] It should be noted that, from T n The sequential accumulation up to T1 means that, for the selected storage line, first accumulate T4, then determine if the value of T4 is greater than the required outbound weight. If it is less, then accumulate T4+T3, and determine if the value of T4+T3 is greater than the required outbound weight. If it is less, then accumulate T4+T3+T2, and determine if the value of T4+T3+T2 is greater than the required outbound weight. If it is greater, then the above accumulation count is 3. In other words, only the 2nd to 4th ton bag conveyor lines need to be running to meet the outbound requirements.

[0039] When ton bags are being shipped out, the selected second to fourth ton bag conveyor lines operate synchronously. When the first ton bag is delivered to the corresponding outbound conveyor line, the second to fourth ton bag conveyor lines pause. The outbound conveyor line then delivers the first ton bag to the outbound lifting platform, which lowers the ton bag onto the outbound conveyor line. The outbound conveyor line then delivers the ton bag to the scanning outbound device. The scanning outbound device scans the ton bag's tag and obtains the material information, then sends the material information to the embedded engineering computer via the CAN bus. The first calculation module subtracts the quantity of ton bags corresponding to the material and the total weight of the ton bags based on the product name. After the scanning outbound device scans one ton bag, the second to fourth ton bag conveyor lines begin delivering the next ton bag. When the cumulative material weight subtracted by the first calculation module in this outbound task first exceeds the outbound weight, the outbound process is complete.

[0040] During the process of ton bag warehousing or outbound, there may be situations where the bag gets stuck. In this embodiment, multiple second camera modules are added to the ton bag conveying path. The ton bag conveying path refers to the path that the ton bag takes when entering or leaving the warehouse. The second camera modules are used to collect images of the ton bags. If the ton bag gets stuck during the conveying process, the second camera modules are used to send the stuck information to the embedded engineering computer. The embedded engineering computer is used to issue an alarm or other operation instructions.

[0041] To provide a more intuitive understanding of the storage status of the shelves, this embodiment adds a display screen, which displays the total number of tonnes of different materials on the shelves, the total weight of the tonnes, and the remaining number of tonnes that can be stored.

The path planning module determines the corresponding outbound path. The embedded engineering computer sends the outbound path signal to the selected ton bag conveyor line, the corresponding outbound conveyor line, the outbound lifting platform, and the outbound conveyor line in the selected storage line via the CAN bus. S203.
