Description

Technical Field

[0001] This invention relates to the field of automated logistics scheduling technology in container inspection workshops, and in particular to a central control scheduling method for container inspection workshops. Background Technology

[0002] As a crucial carrier of goods, containers, after being produced on the container manufacturing line, need to be transported to inspection sites for final inspection, warehousing, and outbound operations. With the expansion of the container industry's production scale, the efficiency of logistics transfer at inspection sites directly impacts the overall production rhythm and operating costs of enterprises. Therefore, improving the automation and intelligence level of inspection workshop operations has become an urgent need for the industry's development.

[0003] Currently, in the container industry, the traditional method of transporting containers from the finished product line to the inspection workshop or site involves using gantry cranes to lift containers onto manually driven vehicles. Drivers then transport the containers to a designated inspection area, where manually driven stackers remove them from the vehicles and place them in their designated locations. This traditional logistics method has several drawbacks: firstly, the entire process requires manual scheduling and placement, making it difficult to monitor site occupancy and inventory levels. Inventory management relies on manual ledgers, resulting in poor accuracy and real-time performance. Secondly, it incurs high logistics, energy, and labor costs, requiring a large number of drivers and operators. These shortcomings hinder the improvement of inspection site operational efficiency and the reduction of operating costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a method for overall control and scheduling of container inspection workshops, which can improve logistics transfer efficiency, reduce labor costs and labor intensity, and enhance the accuracy of inventory management.

[0005] The above-mentioned objective of this invention is achieved through the following technical solutions: A method for overall control and scheduling of a container inspection workshop includes the following steps: S1. When the finished box comes off the production line, obtain the finished box information and allocate a target storage location to the finished box according to the current inventory information and the box inspection progress. S2. Dispatch the four-way shuttle car to transport the finished product box from the production line exit docking point to the designated warehouse docking point; S3. When the number of finished boxes at the warehouse docking point reaches the preset number, the automatic gantry crane is dispatched to hoist multiple finished boxes into the warehouse at one time. S4. When a non-conforming product is found during the inspection, the automatic gantry crane is dispatched to lift the container corresponding to the non-conforming product to a special vehicle at the outbound gate and transport it to the repair area for repair. S5. When the batch of containers has completed the inspection, the automatic gantry crane is dispatched in sequence to lift the batch of containers to the special vehicle at the container exit and transport them to the container yard for storage.

[0006] The above technical solutions enable fully automated scheduling of finished boxes from production line exit, four-way shuttle transfer, automatic gantry crane batch warehousing, handling of defective boxes, to batch box release. This eliminates the need for traditional manual scheduling and recording, reduces labor costs and intensity, minimizes human error, and improves the overall efficiency and operational safety of logistics transfer in the box inspection workshop.

[0007] As a further technical solution of the present invention: the preset quantity is equal to the number of lifting positions that the automatic gantry crane can lift at the same time.

[0008] By using the above technical solution, the preset quantity of batch warehousing is set to the number of lifting positions that the automatic gantry crane can lift at the same time, enabling the automatic gantry crane to carry out batch lifting at full load, reducing the number of lifting operations and back-and-forth trips, and improving the warehousing cycle time and equipment utilization efficiency.

[0009] As a further technical solution of the present invention: the step S1 of allocating target storage locations for the finished product boxes according to the current inventory information and the box inspection progress includes the following sub-steps: S11. Obtain the occupancy status of each storage location; S12. Filter storage locations that are currently idle; S13. Based on the inspection progress, vacant storage spaces near the inspection area or the outbound port will be allocated to the finished product boxes with priority.

[0010] The above technical solution identifies vacant storage locations based on their occupancy status and prioritizes the allocation of vacant locations near the inspection area or outbound gate to finished product boxes, based on the inspection progress. This allows finished product boxes to be stored nearby, facilitating subsequent inspection and outbound processes, reducing transfer distance and operation time, and improving storage space utilization.

[0011] As a further technical solution of the present invention: step S3 also includes: When the number of finished boxes at the warehouse inlet docking station does not reach the preset number, the four-way shuttle car is continuously dispatched to transport the finished boxes to the warehouse inlet docking station until the preset number is reached, and then the automatic gantry crane is dispatched to hoist the finished boxes into the warehouse in batches.

[0012] Through the above technical solution, when the number of finished boxes at the warehouse inlet docking position does not reach the preset number, the four-way shuttle car is continuously dispatched to transport and distribute the finished boxes to the warehouse inlet docking position until the preset number is reached before they are hoisted into the warehouse in batches. This not only ensures the full-load operation of the automatic gantry crane for batch hoisting, but also avoids its frequent empty round trips, significantly improving the efficiency of warehouse entry.

[0013] As a further technical solution of the present invention: In step S4, when there are multiple defective products in the same batch, the automatic gantry crane is scheduled to lift out the containers corresponding to each defective product in sequence.

[0014] With the above technical solution, when there are multiple defective products in the same batch, the automatic gantry crane can be dispatched to lift out the containers corresponding to each defective product in sequence, so that the defective products can be transferred to the repair area in an orderly and centralized manner for repair, avoiding operational chaos and improving the efficiency and standardization of defective product handling.

[0015] As a further technical solution of the present invention: the special vehicle for sequentially scheduling the automatic gantry crane to lift the batch of containers to the container exit in step S5 includes: Based on the order of container inspection completion or storage location, the automatic gantry crane is sequentially dispatched to lift each container to a dedicated vehicle at the container exit, enabling containers to be unloaded from any location.

[0016] Using the above technical solution, automatic gantry cranes are dispatched sequentially to lift each container to a dedicated vehicle at the container exit according to the order of container inspection completion or storage location, enabling containers to be exited from any location. This avoids the inconvenience of the original sequential exit, improves the flexibility and efficiency of container exit, and shortens the waiting time for exiting containers.

[0017] As a further technical solution of the present invention, it also includes: After the batch hoisting and warehousing is completed in step S3, update the occupancy status of the warehouse location where the finished product box is located and the inventory ledger. And / or, after the batch of containers is shipped out in step S5, update the occupancy status of the corresponding storage location and the inventory ledger; The update ensures that inventory records are consistent with the status of storage locations.

[0018] Through the above technical solutions, after the batch hoisting into the warehouse or the batch of containers are shipped out, the occupancy status of the warehouse location and the inventory ledger are updated in a timely manner, so that the inventory records are consistent with the warehouse location status, ensuring consistency between the records and the actual inventory, and improving the accuracy and traceability of inventory management.

[0019] As a further technical solution of the present invention: when the task execution is abnormal, an alarm message is generated and the task is retried or reassigned.

[0020] The above technical solution generates alarm information when a task execution is abnormal, and triggers task retry or reassignment, so that abnormal tasks can be intervened and recovered in a timely manner, ensuring the continuity of operations and improving the reliability and stability of system operation.

[0021] This invention also discloses a central control and scheduling system for a container inspection workshop, used to implement the aforementioned central control and scheduling method for a container inspection workshop, comprising: The warehouse management submodule is used to allocate target storage locations to finished boxes based on current inventory information and box inspection progress, and to generate inbound and outbound tasks. The equipment scheduling submodule is used to receive and decompose the tasks issued by the warehouse management submodule, and schedule the four-way shuttle and automatic gantry crane to perform corresponding operation actions. The four-way shuttle car is communicatively connected to the equipment scheduling submodule and is used to transfer finished product boxes between the production line exit docking point and the warehouse docking point. An automatic gantry crane, which is connected to the equipment scheduling submodule, is used to batch lift finished boxes into the warehouse, lift out unqualified products, and lift out batch containers when the number of finished boxes at the receiving position of the warehouse entrance reaches a preset number.

[0022] Through the above technical solution, by layering and collaborating the warehouse management submodule and the equipment scheduling submodule, and combining the four-way shuttle car and the automatic gantry crane execution equipment, the entire process of finished box warehousing, batch hoisting and unloading is automated, eliminating manual scheduling and recording, and improving logistics transfer efficiency and the overall automation level of the site.

[0023] As a further technical solution of the present invention: the warehouse management submodule includes: The storage location management unit is used to manage the status of each storage location and allocate storage locations to finished product boxes according to the strategy of prioritizing allocation to locations closer to the inbound connection point and prioritizing outbound allocation to locations closer to the outbound side. The inventory management unit is used to record the inventory information and location of finished boxes, and to update the inventory ledger after the task is completed to ensure that the records are consistent with the actual inventory. The task management unit is used to receive inbound applications and outbound instructions, generate inbound tasks and outbound tasks, and send them to the equipment scheduling submodule.

[0024] Through the above technical solutions, the coordinated operation of the location management unit, inventory management unit, and task management unit enables unified coding and status management of storage locations, maintenance of inventory ledgers, and generation and distribution of inbound / outbound tasks. This ensures consistency between the records and the actual inventory, and improves the accuracy of inventory management and the planning and visualization of warehousing operations.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention discloses a method for overall control and scheduling of a container inspection workshop. It obtains finished container information and allocates target storage locations, schedules four-way shuttle vehicles to transfer finished containers to the receiving position at the inbound port, schedules automatic gantry cranes to hoist the containers into the warehouse in batches when the quantity reaches a preset quantity, and hoists containers that fail inspection to the outbound port when they fail inspection, and hoists them to the outbound port in sequence when the batch is completed, thereby realizing the fully automated scheduling of the inbound, inspection and outbound process.

[0026] 2. This invention discloses a container inspection workshop central control and scheduling system, which allocates storage locations and generates tasks through a storage management submodule and schedules four-way shuttle cars and automatic gantry cranes to perform operations through an equipment scheduling submodule, thereby realizing the fully automated scheduling of the entire process of warehousing, batch hoisting, non-conforming product handling and batch container output.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example

[0034] Reference Figure 1 The container inspection workshop of this invention is divided longitudinally into four parallel zones: A, B, C, and D. Each zone has five rows of container spaces, totaling 2,000 standard container spaces, compatible with both 20-foot and 40-foot containers. Each container space is identified using a unified coding system, with the coding format being "zone number, row number, container space number". For example, container space number 1 in row 1 of zone A is coded as "A 01 001". Each zone has approximately 500 container spaces, facilitating cargo management and task location. The site includes production line exit docking stations, inbound docking stations, outbound exits, and container exits. The production line exit docking station receives finished containers transferred from the finished product line; the inbound docking station temporarily stores finished containers awaiting warehousing; and the outbound and container exits are used for the removal of non-conforming products and the removal of conforming batches, respectively. Four sets of automatic gantry crane travel tracks are arranged longitudinally on one side of the workshop. Each automatic gantry crane corresponds to one travel track and travels and operates independently, covering each work area to complete the lifting operation. There are also four-way shuttle car travel tracks in the site, and the work areas are connected by the tracks to form a complete logistics channel.

[0035] Reference Figure 4 The container inspection workshop central control and scheduling system of the present invention includes central control and scheduling software, a four-way shuttle, and an automatic gantry crane. The central control and scheduling software is the control hub of the entire system, and has both warehouse management and equipment scheduling functions. It mainly includes a warehouse management submodule and an equipment scheduling submodule, and interfaces with ERP, MES, or production line systems through an uplink interface to receive inbound and outbound business instructions, and communicates with the executing equipment through a downlink interface to receive equipment status and operation feedback.

[0036] The warehouse management submodule is used to allocate target storage locations for finished goods boxes based on current inventory information and box inspection progress, and to generate inbound and outbound tasks. Internally, it is further divided into a location management unit, an inventory management unit, and a task management unit. The location management unit is used for unified coding and status management of each storage location, supporting switching between states such as idle, pending inbound, already inbound, pending outbound, already outbound, and abnormally locked. It allocates storage locations to finished goods boxes based on a strategy of prioritizing allocation to locations closer to the inbound connection point and prioritizing outbound from locations closer to the outbound side. The inventory management unit records the inventory information and storage location of finished goods boxes, and updates the inventory ledger after task completion to ensure consistency between the ledger and the actual inventory. The task management unit receives inbound applications and outbound instructions, and generates inbound and outbound tasks.

[0037] The equipment scheduling submodule is used to receive and decompose the tasks issued by the warehouse management submodule, sort and plan the routes of the tasks, issue action instructions to the corresponding execution equipment, and is responsible for equipment coordination and exception handling.

[0038] The four-way shuttle is used to transfer finished product boxes between the production line exit and inbound docking points. It includes a vehicle body, a traveling mechanism, a lifting mechanism, a hoisting mechanism, and a control system. The lower part of the vehicle body has two sets of orthogonally arranged wheels, enabling four-way travel by switching between the wheels, allowing for direction changes without turning. The traveling mechanism is driven by a motor, which moves the wheels along the track. The lifting mechanism lifts the finished product boxes, with its lifting platform contacting a fixed ground platform for cargo transfer. The hoisting mechanism uses a rack and pinion synchronous lifting structure, driven by a DC servo motor, ensuring smooth lifting and high load capacity. The vehicle body is equipped with a stainless steel QR code positioning and recognition device, which achieves precise positioning by reading QR codes on the ground. The four-way shuttle has a load capacity of 5 tons, is powered by a 96V 80AH battery, and has an adjustable longitudinal speed of 0 to 120 m / min and an adjustable lateral speed of 0 to 60 m / min, allowing for continuous 24-hour operation. The vehicle supports both fully automatic and semi-automatic control modes. Internally, it features a RES (Remote Automation) underlying control system that breaks down task requirements from the equipment scheduling submodule into specific instructions to perform actions such as picking up, placing, and storing finished product boxes. Multi-vehicle collaborative scheduling is achieved through networking. This solution includes two charging points on-site, with a total of eight four-way shuttle vehicles. Four are in use, and four are charging, ensuring continuous 24-hour operation through rotation.

[0039] Reference Figure 2The automated gantry crane is a portal frame structure, comprising a gantry frame, a trolley traveling mechanism, a hoisting mechanism, a spreader, and a control system. The gantry frame consists of supporting columns on both sides and a top beam atop the columns. Each automated gantry crane has four lifting trolleys mounted on the top beam, forming four lifting positions. Each lifting position corresponds to a lifting operation unit, with adjacent positions spaced apart. Each lifting operation unit includes a lifting linkage and a spreader connected to the lifting trolley. An upper lifting module is suspended below the spreader, and this upper lifting module is raised and lowered via the hoisting mechanism, corresponding to the stationary lower module. This automated gantry crane, through the coordinated operation of its four lifting positions, can simultaneously lift four containers at a time, achieving batch lifting. The trolley traveling mechanism drives the entire gantry frame along ground tracks, and the hoisting mechanism raises and lowers the spreader via wire ropes or chains. The spreader is used to grab containers. The automatic gantry crane has a rated lifting capacity of 5 tons for a container plus spreader weight. It employs a control system combining full automation and remote control from a central control room. An absolute encoder is installed in the trolley's traveling direction, working in conjunction with a ground-based absolute position code for positioning, achieving a positioning accuracy of ±10mm. An absolute encoder, laser rangefinder, and cam limit switch are used in the lifting direction for positioning and anti-collision control, achieving a positioning accuracy of ±5mm. The automatic gantry crane is equipped with a comprehensive safety protection system, including a laser radar anti-collision system located beneath the crane, a personnel safety helmet positioning system, a personnel intrusion detection system based on a Hikvision intelligent network video recorder, and an electronic fence. A safety PLC or independent safety relay is used for emergency stop, collision prevention, and anti-collision interlocking. Safety signals can directly cut off the gantry's power circuit to ensure operational safety. As a lifting execution device, the automatic gantry crane communicates with the equipment scheduling submodule, used for batch lifting of finished containers into the warehouse when the number of finished containers at the receiving position reaches a preset quantity, lifting out non-conforming items, and transporting batch containers out of the warehouse. The automatic gantry crane's control system uses a high-performance industrial PLC as the main controller. The hoisting mechanism uses a dedicated hoisting frequency converter with encoder closed-loop control, and the trolley travel uses a dedicated vector control frequency converter. The coordinated actions of each mechanism realize automatic box retrieval and placement. The automatic gantry crane communicates with the central control and dispatch software via industrial Ethernet. The communication protocol uses TCP / IP plus standardized messages, and the central control issues the warehouse entry command and location number.

[0040] In terms of connectivity, the warehouse management submodule interfaces with ERP, MES, or production line systems via an uplink interface to receive inbound and outbound business instructions. After generating inbound and outbound tasks, it sends the tasks to the equipment scheduling submodule via an internal interface. After receiving and decomposing the tasks, the equipment scheduling submodule sends action instructions to the four-way shuttle and the automatic gantry crane via a downlink interface, and receives execution feedback and equipment status from both. The four-way shuttle and the automatic gantry crane are communicatively connected to the equipment scheduling submodule, and both, as execution equipment, complete their respective transfer and hoisting operations under the command of the equipment scheduling submodule.

[0041] Reference Figure 3 A method for overall control and scheduling of a container inspection workshop includes the following steps: S1. When the finished boxes come off the production line, obtain the finished box information and allocate target storage locations to the finished boxes according to the current inventory information and the box inspection progress. Step S1, allocating target storage locations to the finished boxes according to the current inventory information and the box inspection progress, includes the following sub-steps: S11. Obtain the occupancy status of each storage location; S12. Filter storage locations that are currently vacant; S13. According to the box inspection progress, prioritize allocating vacant storage locations near the inspection area or the outbound side to the finished boxes, so that the finished boxes are stored nearby, facilitating subsequent box inspection and outbound processes. S2. The four-way shuttle is dispatched to transport the finished product boxes from the production line exit docking point to the designated warehouse docking point. The four-way shuttle is equipped with an RES underlying control system, which decomposes the task requirements issued by the equipment scheduling submodule into corresponding specific instructions to complete the actions of picking up, placing, and storing the finished product boxes. During the movement, the shuttle reads the ground QR code through a stainless steel QR code positioning and recognition device to calculate its own position. Multiple four-way shuttles are networked to achieve multi-vehicle collaborative scheduling and collect and distribute the finished product boxes at the warehouse docking point. S3. When the number of finished containers at the inlet docking station reaches a preset quantity, the automatic gantry crane is dispatched to lift multiple finished containers into the warehouse at once. The preset quantity is equal to the number of lifting positions that a single automatic gantry crane can simultaneously lift. In this embodiment, each automatic gantry crane has 4 lifting positions, so the preset quantity is 4. When the number of finished containers at the inlet docking station does not reach the preset quantity, a four-way shuttle is continuously dispatched to transport finished containers to the inlet docking station until the preset quantity is reached. Then, the automatic gantry crane is dispatched to lift and load the containers into the warehouse in batches, allowing the automatic gantry crane to operate at full capacity. The automatic gantry crane performs the inlet operation in the following sequence: The equipment dispatching submodule issues a task, including the container retrieval position and the container placement position; the automatic gantry crane trolley moves to the container retrieval position; the lifting mechanism lowers, and the spreader grabs the container; after confirming successful grabbing, it is lifted to a safe height; the trolley moves to the target stacking position; the lifting mechanism lowers to the specified stacking height and the container is released; the spreader returns to the standby height, the task is completed, and feedback is provided. S4. When non-conforming items are found during container inspection, the automated gantry crane will be dispatched to lift the corresponding container out of the warehouse to a dedicated vehicle at the outbound exit and transport it to the repair area for maintenance. When multiple non-conforming items exist in the same batch, the automated gantry crane will be dispatched to lift the corresponding containers of each non-conforming item out in sequence. S5. When a batch of containers completes inspection, the automated gantry cranes are dispatched sequentially to lift the containers to designated vehicles at the exit, which then transport them to the container yard for storage. This sequential dispatching of the automated gantry cranes to the designated vehicles at the exit includes: according to the order of inspection completion or storage location, the automated gantry cranes are dispatched sequentially to lift each container to a designated vehicle at the exit, enabling containers to be removed from any location. The automated gantry cranes execute outbound operations in the following sequence: the equipment dispatch submodule issues the task, including the container retrieval and placement positions; the trolley moves to the retrieval position, lifts and lowers to grab the container, and lifts it to a safe height; the trolley moves to the truck parking space at the exit; after the anti-collision system confirms that the truck cab is outside the safe area, it slowly lifts and lowers; the container is lowered onto the truck flatbed, and the spreader is released; the crane returns to the standby height, and the task is completed.

[0042] In addition, after the batch loading and warehousing is completed in step S3, or after the batch container is unloaded in step S5, the occupancy status of the warehouse location where the finished container is located and the inventory ledger are updated to ensure that the inventory records are consistent with the warehouse location status; when the task execution is abnormal, alarm information is generated and task retry or reassignment is triggered.

[0043] The implementation principle of this invention is as follows: This method uses a central control and scheduling software as its core, and through its warehouse management submodule and equipment scheduling submodule, it realizes the allocation of finished product container storage locations, maintenance of inventory ledgers, generation of inbound and outbound tasks, and scheduling of execution equipment. The warehouse management submodule completes the allocation of storage locations and task generation through the location management unit, inventory management unit, and task management unit. The equipment scheduling submodule receives and decomposes the tasks issued by the warehouse management submodule, and schedules the four-way shuttle and automatic gantry crane to perform the corresponding operation actions. Among them, the four-way shuttle, as the transfer execution equipment, transfers finished product containers between the production line exit connection point and the warehouse entry connection point, and can collect and distribute finished product containers at the warehouse entry connection point to provide quantity preparation for the batch lifting of the automatic gantry crane; the automatic gantry crane, as the lifting execution equipment, lifts finished product containers into the warehouse in batches when the number of finished product containers at the warehouse entry connection point reaches the preset quantity, and lifts out unqualified products to the dedicated vehicle at the exit point when inspection is found, and lifts batch containers to the dedicated vehicle at the exit point in sequence when the batch of containers has completed inspection. By working collaboratively with the warehouse management submodule, equipment scheduling submodule, and execution equipment such as four-way shuttle cars and automatic gantry cranes, the entire process of automated scheduling is achieved, from finished box unloading, warehouse location allocation, four-way shuttle car transfer, batch warehousing, handling of defective products after inspection, to batch unloading. This eliminates the need for traditional manual scheduling and recording methods, improves the efficiency of logistics transfer in the inspection workshop, reduces labor costs and labor intensity, and enhances operational safety and inventory management accuracy.

[0044] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
