Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing industry, in particular to a blank separation storage and transportation system for a stamping factory. Background Art

[0002] In stamping plants such as automobile manufacturing, the storage and management of blanks (i.e. raw materials that have not been stamped) is a key link in production efficiency and cost control. In traditional stamping plants, blanks are usually stored on blank pallets, which are then placed on shelves or on the ground and rely on manual forklifts for storage and retrieval. This method has obvious limitations: the forklift operator needs to clearly remember the storage location and driving route of each blank, which not only increases the complexity of the operation, but also easily leads to fatigue driving due to long-term repetitive labor and high-intensity work, increasing the risk of safety accidents. In addition, some stamping plants have tried to use blank stereoscopic warehouses to store blanks. Although this method can reduce the floor space and improve storage efficiency to a certain extent, its high cost and the problem of being unable to pick up and place blanks when the stacker fails still seriously affect the continuity and cost efficiency of production. In the process of transporting from the stereoscopic warehouse to the stamping line, manual operation is still required, and the degree of automation of this process is not high and the efficiency is low.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example: Please refer to the attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a blank separation storage and transportation system for a stamping factory, comprising: Blank trays, which are used to carry blanks in stamping plants; An RFID electronic tag is provided on the blank tray and is used to store the model information of the blank; The RFID reader / writer at the blank storage location is used to read and write the contents of the RFID electronic tag; The blank warehouse management system is connected to the RFID reader and is used to manage the blanks; An automatic transfer device scheduling system, which is connected to the blank warehouse management system and is used to schedule the automatic transfer device to transfer the blank; The stamping line control system is connected to the automatic transfer device scheduling system, which is used to provide the stamping line with demand information for blanks.

[0021] Specifically, this system realizes full automation of blank management through the cooperation of the above system modules, significantly improves production efficiency, reduces labor costs, and enhances the response speed and flexibility of the production line. And through the use of automated equipment, it reduces the need for manual operation, speeds up the storage and retrieval of blanks, and reduces production delays.

[0022] The RFID electronic tag on the blank pallet stores the model information of the blank, which can be read and written by the RFID reader / writer in the blank storage location, thus realizing real-time tracking and management of the specific information of the blank.

[0023] The blank warehouse management system is directly connected to the RFID reader / writer to centrally manage blank data, ensuring the accuracy and reliability of blank inventory.

[0024] The automatic transfer device scheduling system automatically dispatches unmanned handling equipment, such as unmanned forklifts or AGVs, according to the demand signal of the stamping line to retrieve and transport the blanks from the warehouse to the designated stamping line location.

[0025] When the stamping line needs blanks, the stamping line control system sends a demand signal to the automatic transfer device scheduling system.

[0026] The scheduling system analyzes the demand and queries the specific storage location of the blanks through the blank warehouse management system.

[0027] Once the location is determined, the dispatching system instructs the unmanned handling equipment to go to the corresponding location and pick up the blank pallet with the correct RFID tag.

[0028] Unmanned handling equipment transports the blanks to the stamping line safely and efficiently. The entire process is monitored in real time by the system to ensure efficient and safe operations.

[0029] The above system design not only optimizes the storage and management of blanks and reduces downtime in production, but also improves work efficiency and safety by reducing manual intervention.

[0030] The blank warehouse management system includes: A data management module, which is used to store and manage the model and inventory information of the blanks; A communication module, which is used to communicate with the RFID reader to obtain blank information; A location management module is used to track and manage the location information of the blank storage location; Safety monitoring module, which is used to monitor the stock status of blanks and issue an alarm in abnormal situations; The user interface module is used to provide a human-computer interaction interface for operators to monitor and manage blank inventory.

[0031] Specifically, the core function of the data management module is to store detailed information of the blanks, such as model, quantity and specifications, and manage these data. Data updates are usually achieved through interaction with RFID readers to ensure the real-time and accuracy of the information.

[0032] The communication module is responsible for communicating with the RFID electronic tag on the blank tray through the RFID reader / writer to obtain and update the blank information in real time. This module ensures the stability and reliability of data transmission.

[0033] The location management module is used to monitor and record the specific location information of each blank pallet, supporting efficient storage location management and fast material retrieval.

[0034] The safety monitoring module monitors the inventory status of blanks. If the quantity is lower than the safety level or a system abnormality is detected, an alarm will be immediately sent to the management personnel so that corresponding measures can be taken.

[0035] The user interface module provides an intuitive interface for warehouse managers to monitor inventory status, view alarm information, make inventory adjustments and other daily operations, making inventory management more intuitive and convenient.

[0036] Achieve efficient inventory updates and management through automated systems to reduce material shortages and surpluses.

[0037] Real-time monitoring and early warning systems help prevent the risk of inventory depletion and ensure continuous operation of production lines.

[0038] The location management module helps to quickly locate blanks, reduce internal transportation time, and optimize logistics processes.

[0039] With centralized data management and a user-friendly interface, management can make more effective strategies and decisions based on accurate inventory data.

[0040] The automatic monitoring system reduces safety risks caused by human negligence and responds promptly to possible inventory anomalies or equipment failures.

[0041] The automatic transfer device scheduling system includes: A path planning module, which is used to generate a driving route for the automatic transfer device according to the blank demand information of the stamping line and the blank location information in the warehouse; The task allocation module is used to allocate picking and transportation tasks to the automatic transfer device.

[0042] Specifically, automated path planning and task allocation significantly improve the speed and accuracy of material handling, ensuring the timely supply of blanks, thereby optimizing the operating efficiency of the entire production line.

[0043] By optimizing travel routes and accurately dispatching tasks, the automatic transfer device dispatching system reduces delays caused by material waiting or improper route selection.

[0044] The automated system reduces reliance on manual operations, reduces costs that may be caused by human errors, and reduces labor costs.

[0045] The path planning module uses advanced algorithms to analyze the current inventory location and the needs of the stamping line and calculate the most efficient route. This module ensures that automated transfer devices, such as unmanned forklifts or AGVs, move along the shortest or optimal path, saving time and energy.

[0046] The task allocation module is based on the real-time demand of the stamping line and the location information of the blank. This module is responsible for assigning specific picking and transportation tasks to each automatic transfer device. It performs intelligent scheduling based on task priority and equipment availability in the system to balance workload and optimize overall operational efficiency.

[0047] When the stamping line submits new blank requirements, the system first analyzes the optimal path between the demand point and the storage point through the path planning module.

[0048] The task allocation module then allocates the task to a specific automatic transfer device, instructing it to go to a specific location to pick up the specified blank.

[0049] The automatic transfer device travels to the blank storage location along the specified path, obtains the blank, and transports it safely to the stamping line.

[0050] During the entire process, the system monitors the execution status of each task and the operating status of the transfer device to ensure that the task is completed as planned.

[0051] The system improves production efficiency by reducing idle time in material handling and transportation, ensuring that the production line always has sufficient blank supply. Automated scheduling and path planning maximize the operating efficiency of the transfer device, reducing energy consumption and equipment wear. The system's automated design reduces production interruptions caused by human operating errors and enhances the reliability and stability of the entire production process.

[0052] The press line control system includes: Production planning module, which is used to provide demand information for blanks on the production line; The interface module is used to communicate with the automatic transfer device scheduling system to transmit production demand information.

[0053] The navigation mode of the automatic transfer device is one or more of visual navigation, magnetic stripe navigation or laser navigation.

[0054] Specifically, by timely transmitting production demand information, the stamping line control system ensures that the automatic transfer device can quickly respond to changes in production demand, thereby reducing waiting time and improving production efficiency.

[0055] The communication capabilities of the interface modules allow the system to quickly adapt to changes in production line requirements and adjust logistics and production strategies in real time.

[0056] The production planning module can formulate or adjust production strategies based on current production status and future forecasted demand to maintain the continuity and efficiency of the production process.

[0057] The production planning module generates and updates the demand information of blanks in real time according to the actual operation of the production line and the predetermined production plan. It takes into account various variables such as machine operation speed, order demand, inventory level, etc. to ensure the efficient operation of the production line.

[0058] The interface module is responsible for transmitting the blank demand information generated by the production planning module to the automatic transfer device scheduling system. This module uses advanced communication technologies such as wireless networks and API interfaces to ensure real-time transmission and accuracy of data.

[0059] The production planning module first determines the type and quantity of blanks required for the production line and generates demand information.

[0060] These demand information are transmitted to the automatic transfer device scheduling system in real time through the interface module.

[0061] After receiving the information, the automatic transfer device scheduling system dispatches the corresponding automatic transfer device according to production needs, and uses the preset navigation system to ensure that the blanks can be accurately and timely transported from the warehouse to the designated production line location.

[0062] During the entire process, the system monitors the supply status of the blanks and the operation status of the production line to ensure that production is not interrupted.

[0063] The system prevents production interruptions by precisely controlling the supply of blanks, thereby maintaining the continuous operation of the production line. Rapidly responsive supply chain scheduling reduces production preparation time and downtime caused by material shortages. Accurate demand forecasting and real-time scheduling reduce excessive inventory and resource waste, and optimize production cost management.

[0064] The blank warehouse is a traditional warehouse or a high-rise warehouse.

[0065] The communication between RFID tags and RFID readers is based on wireless radio frequency technology.

[0066] The automatic transfer device can be an unmanned forklift or AGV.
