Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber storage, and in particular to a single-box storage and management method for carbon fibers. Background Art

[0002] Carbon fiber is a high-strength, lightweight composite material with a wide range of applications. During the manufacturing and storage process, temperature and humidity conditions play an important role in the quality and performance of carbon fiber. Appropriate temperature and humidity conditions ensure that the carbon fiber is not damaged during storage and maintains its excellent performance. For example, high temperature and high humidity environments may cause carbon fiber to absorb moisture, increase its weight, increase its volume, and make it difficult to handle and use. At the same time, the absorption of moisture will reduce the strength and stiffness of the carbon fiber, and may even cause mildew. A humid environment will cause the resin of the carbon fiber cloth to decompose or soften, which will cause the carbon fiber cloth to delaminate or peel off, and lose its reinforcement effect. In a dry and well-ventilated environment, if the carbon fiber is in an incorrect storage environment, it may be squeezed or twisted, which may reduce the performance of the carbon fiber. Due to the above problems, additional maintenance and replacement costs may be required to maintain the performance of the carbon fiber material. In order to avoid these disadvantages, it should be ensured that the carbon fiber material is stored in a dry, well-ventilated, and temperature-appropriate regular environment. Summary of the invention

[0003] The purpose of the present invention is to provide a carbon fiber cargo box storage and transportation equipment and method, so as to solve the problem raised in the above background technology that in the process of storing carbon fiber materials, due to the uncertainty of the storage environment, the quality of carbon fiber is prone to decline if the storage is improper, which may increase the additional cost of maintaining the carbon fiber. The present invention proposes to adopt a single-box storage method to solve the drawbacks of heat storage such as carbon fiber stacking, so as to prevent the accumulation of carbon fiber and the generation of a large amount of heat, which in turn causes the quality of carbon fiber to decline. The storage and management of single-box vertical warehouses completely avoids the inconvenience of inventorying materials after the use of stacking. In order to ensure the accuracy of the inventory, personnel will inevitably cause damage to the packaging, which greatly increases the cost of carbon fiber packaging.

[0004] In order to achieve the above object, the present invention provides the following scheme:

[0005] A method for storing and managing a single carbon fiber cargo box:

[0006] Carbon fiber boxes are transported on the carbon fiber box conveyor line, which is equipped with a code photo detection to detect whether the box code meets the requirements. When the box meets the requirements, it is transported to the workstation. If it does not meet the requirements, it is transported to the wrong box processing area. When the box is transported to the workstation, the conveyor line starts the second code photo detection. At this time, the detection work is information entry, and the read information is uploaded to the warehouse management system data center. The data center allocates the carbon fiber box position to the shelf according to the code rules established in advance.

[0007] The workstation lifts the carbon fiber cargo box. When the workstation lifts the cargo box to full load, the workstation stops working and sends a receiving signal. After the workstation sends the receiving signal, the material box robot drives to the workstation through landmarks or 5G signal navigation to receive the carbon fiber cargo box. After the material box robot takes the carbon fiber cargo box, it drives to the corresponding shelf position through the shelf position allocated by the data center to release the goods.

[0008] When it is time to ship out, the ERP system sends a command to the warehouse control system according to the order number to carry out the corresponding cargo box shipping process. The material box robot drives to the corresponding cargo box location number to pick up the goods, and then transports them to the shipping workstation to ship out the carbon fiber cargo box. The shipping workstation unloads the single box and sends it to the unloading conveyor line, thus completing the transportation and storage of the carbon fiber cargo box.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention can reduce maintenance and replacement costs to maintain the performance of the carbon fiber material and ensure that the carbon fiber material is stored in a dry, well-ventilated, and temperature-appropriate regular environment.

[0011] The present invention realizes seamless connection, avoids the problem of incompatibility between systems, and integrates production and storage control.

[0012] The present invention can avoid the influx of wrong boxes and erroneous information, making the management of carbon fiber cargo boxes more formal and correct; it can also improve inventory accuracy, optimize inventory management, and timely adjust inventory and market management strategies through regular inventory analysis of inventory data, reduce inventory costs, and provide convenience for company audits.

[0013] The present invention adopts a large-scale regular vertical warehouse. Compared with the traditional warehouse, the humidity and temperature in the storage space are suitable, which is more suitable for the storage of carbon fiber cargo boxes, avoiding the problem of carbon fiber quality degradation due to humidity, crowding and high temperature storage during storage.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 2 , the present invention provides a specific technical solution:

[0018] The present invention provides the following solutions:

[0019] A method for storing and managing a single carbon fiber cargo box is established on the following ERP or MES system. The ERP or MES system is used as a bridge between storage equipment and production operations. It is connected with the equipment management system, background management system, warehouse management system, central control system, etc. With the ERP system as the most basic logic, it integrates four major systems, namely, warehouse management system, background control system, central control system, and equipment management system. It achieves seamless connection, avoids the problem of incompatibility between systems, and integrates production and warehouse control.

[0020] The vertical warehouses used in the present invention are not large-scale regular vertical warehouses.

[0021] Under the above main systems, the following specific storage and management methods are carried out:

[0022] The carbon fiber boxes on the S001 single-box conveyor line are conveyed from the packaging. The conveyor line is equipped with a photo detection to detect whether the box code meets the requirements. The detection standard is detected according to the ERP push requirements. If it meets the requirements, the carbon fiber box conveyor line continues to operate; if it does not meet the requirements, the conveyor line will transfer the carbon fiber box to the wrong box processing line for manual processing of the wrong box. The manual processing of the wrong box includes manual pushing of the box code, weight detection, and box size detection. The carbon fiber boxes that meet the requirements are conveyed to the secondary photo taking place. The purpose of the photo taking here is to read the box code of the carbon fiber box, and the data is transmitted to the central control system for subsequent warehousing preparation.

[0023] In some embodiments, the inspection criteria include whether the box code format is qualified, whether the box code is repeated, and whether the box code information is correct.

[0024] In some embodiments, the warehousing management is carried out by the front-end conveyor line to the box code primary photo inspection site to detect whether the box code meets the warehousing standards. If it meets the warehousing standards, the conveyor line continues to transport it to the box code secondary photo inspection site.

[0025] If the product fails to meet the requirements in the first photo inspection, it will be transported to the manual processing circulation line for manual processing. After the manual processing is completed, it will be sent to the box code first photo inspection station for inspection.

[0026] The purpose of the second camera inspection of the box code is to read the box code information and push it to the warehouse management system. Inventory management is to allocate the shelf location according to weight, quality grade, batch, production line number, time and other information. The allocation principle is that the same type is prioritized in one row, and the weight is placed from top to bottom on the shelf from light to heavy.

[0027] In some embodiments, the central control system is used to build and control peripheral equipment through IWMS, WCS, RCS, ERP, and MES protocols, including model building, operation management, data management, view management, etc.

[0028] In some embodiments, the central control system includes using software to build a three-dimensional model, and then marking the location number of each location, which is consistent with the actual location; the walking route of the material box robot is also established in the model and marked in the actual warehouse using different sensors, and each sensor number is consistent with the location number in the model, and the material box robot moves according to the sensor marked position to achieve walking.

[0029] Model establishment includes map establishment; establishment of shelf codes and warehouse location models of storage shelves; establishment of model of material box robot vehicles, etc. The central control system establishes a virtual model based on the actual construction form of multi-layer shelves. The virtual model and the actual shelf location codes are consistent, and the central control system performs virtual modeling of the shelf aisle walking routes with reference to the surrounding physical objects.

[0030] Operation management includes task management, interface information control, and scheduling control of warehousing and transportation systems.

[0031] Task management, specifically task running status, task cancellation, suspension and establishment, etc.; interface information control includes RCS interface information control and three-party information control; control scheduling includes RCS task interaction, ERP task interaction, etc. S002 carbon fiber cargo box is transported to the warehouse lifting workstation. The workstation lifts the carbon fiber cargo box by box. After the workstation lifts the carbon fiber cargo box to a certain number, the specific number is currently available on the market. There are workstations that lift 7 or 9 boxes, which can be customized according to actual conditions. The workstation sends a signal to the central control system. After the central control system allocates the storage positions of the carbon fiber cargo boxes in turn, the material box robot automatically drives to the front of the workstation and transfers the carbon fiber cargo box with the warehouse lifting workstation. After the carbon fiber cargo box is transferred to the material box robot, the material box robot drives to the multi-layer shelf according to the 5G signal. The central control system has already established the multi-layer shelf model and the walking route modeling. The material box robot drives to the already allocated shelf position under the guidance of the 5G signal. After arriving at the shelf position, the material box robot enters the warehouse according to the allocated position. After a certain number of carbon fiber cargo boxes have been put into storage, the outbound operation will be carried out. The outbound operation is carried out according to the formula logic edited in advance.

[0032] During the outbound process, the central control system sends information to the material box robot. According to the information, the material box robot drives to the multi-layer shelf to pick up the designated carbon fiber cargo box on the multi-layer shelf. After receiving the carbon fiber material box, it is guided to the outbound landing workstation according to the 5G signal.

[0033] In some embodiments, a specific method is provided for outbound management in carbon fiber transportation, specifically in three aspects:

[0034] The first aspect is order delivery. After receiving the order from sales, ERP sends it to the warehouse management system and then issues the delivery command.

[0035] The second aspect is automatic outbound delivery. The warehouse management system spontaneously generates instructions to carry out outbound delivery according to the automatic outbound delivery rules.

[0036] The third aspect is manual outbound delivery, which uses PDA tools to form a connection with the warehouse management system, and manually specifies the outbound delivery process of the cargo code on the PDA.

[0037] The above warehousing management can realize warehousing management and avoid the influx of wrong boxes and wrong information, making the management of carbon fiber cargo boxes more formal and correct.

[0038] The warehouse management system is specifically used in the outbound process. In addition, the warehouse management system can manage outbound delivery, inbound delivery, inventory, location, inventory, and interface management.

[0039] In some embodiments, the warehouse management system performs inventory management with the aim of improving inventory accuracy and optimizing inventory management. By regularly counting and analyzing inventory data, inventory and market management strategies can be adjusted in a timely manner to reduce inventory costs and facilitate company audits.

[0040] In some embodiments, the warehouse management system performs interface management, connects the system data interfaces such as CMS, DATABUS, MES, ERP, WCS, etc., ensures the intercommunication and push of information data between systems, and provides a basic bridge for realizing the mutual coordination of the whole machines and information call.

[0041] In some embodiments, the warehouse management system performs data test conversion: data test conversion includes information storage, information processing, information transmission; functional testing, information search and other contents.

[0042] In some embodiments, the warehouse management system can display dynamic views, which include data visualization and data processing. The data visualization is provided with a dedicated interface board to display the real-time position of the material box robot, a three-dimensional stereoscopic diagram of the shelf, and a dynamic display of the position and action of the material box robot. Data processing includes submitting specified data to the upper system, sending a request to the upper system for specified data, and editing the relational database.

[0043] In some embodiments, the client is visualized in the warehouse management system, and the client visualization is a view of the client, including PC workstation and PDA data operations, information task publishing, etc., including the PC-side storage number display, the number of vacant warehouse locations display, the location status display, and the display of detailed information on carbon fiber cargo boxes in each row and column of locations, etc. The monthly incoming inventory, shipment volume, return volume, shipment comparison of each type of product, comparison of shipment types in the previous and next few months, and line chart presentation can be displayed on a dedicated screen, making it convenient for managers to view market conditions and product sales status at any time based on data.

[0044] The S003 outbound landing workstation is the same as the inbound lifting workstation, both of which have the functions of lifting and lowering. After the outbound landing workstation and the material box robot dock with the carbon fiber cargo box, the outbound landing workstation puts the carbon fiber cargo box one by one on the unloading and stacking conveyor line. On the unloading and stacking conveyor line, the carbon fiber cargo box is photographed and inspected, and the carbon fiber cargo box that meets the outbound process is sent to the stacking station, while the carbon fiber cargo box that does not meet the outbound process is sent to the manual unloading outlet and transferred to the inbound end for re-warehousing.

[0045] Specifically, during the entire storage and management process, there are box code errors due to packaging errors. After the box code error, the manual request to ERP is made to cancel the box code process. ERP pushes the box code cancellation information and the new box code information to the central control system. For carbon fiber boxes that have not been put into storage, the central control system will handle the wrong box at the box code reading (secondary photography) and manually change the box code on the manual processing line, and then proceed with the storage process. For carbon fiber boxes that have been put into storage, the central control system will push the information to the manual person, who will manually carry out the outbound process, and then after the box code is changed, the storage process will be carried out again.

[0046] A specific embodiment is provided. The case where a packaging error occurs and a box code error occurs is when the packing personnel pastes the box label incorrectly, an error occurs during printing, and a problem is found during re-inspection after storage and needs to be corrected.

[0047] Specifically, the backend control system includes the interface control of three major systems, namely the warehouse control system, intelligent warehouse management system, and content management system, the algorithm for the operation of the material box robot, and the overall planning of the intelligent warehouse. The equipment management system mainly includes the control of the front-end and back-end conveyor lines, camera detection, workstations, material box robots, and PC-side equipment.

[0048] The present invention realizes the transportation of carbon fiber cargo boxes, information detection, workstation lifting, material box robot handling, storage and warehousing, and other actions and information interaction between devices. The regular transportation process avoids mechanical damage to the packaging of carbon fiber cargo boxes during manual handling and forklift transportation. At the same time, high, large, and empty shelves avoid the problem of carbon fiber quality degradation during storage due to humidity, crowding, and high temperature storage.

[0049] The present invention provides specific embodiments as follows:

[0050] Step 1: Take photos of the carbon fiber boxes on the single-box conveyor line and inspect them according to the inspection standards pushed by the ERP or MES system;

[0051] Step 2: The carbon fiber cargo boxes that meet the requirements are transported along the conveyor line to the secondary photo taking station for taking photos and reading the box codes of the carbon fiber cargo boxes; the conveyor line that does not meet the requirements transfers the carbon fiber cargo boxes to the wrong box processing line for manual wrong box processing; the box code reading data of the secondary photo is transmitted to the central control system for storage preparation;

[0052] Step 3: The carbon fiber cargo box is transported to the warehouse lifting workstation to complete the single-box lifting of the carbon fiber cargo box;

[0053] Step 4: After the workstation lifts a certain number of carbon fiber boxes, the workstation sends a signal to the central control system. After the central control system allocates the positions of the carbon fiber boxes in sequence, the box robot automatically drives to the front of the workstation and exchanges the carbon fiber boxes with the storage lifting workstation. After the carbon fiber boxes are handed over to the box robot, the box robot drives to the multi-layer shelf according to the guidance of the 5G signal.

[0054] Step 5: After arriving at the assigned shelf position, the material box robot enters the warehouse according to the assigned storage position;

[0055] Step 6: After a certain number of carbon fiber boxes have been put into storage, the outbound operation will be carried out.

[0056] Step 7: During the outbound process, the central control system sends information to the material box robot, which drives to the multi-layer shelf according to the information to pick up the designated carbon fiber box on the multi-layer shelf. After picking up the carbon fiber material box, the robot is guided to the outbound landing workstation according to the 5G signal;

[0057] Step 8: After the outbound landing workstation and the material box robot dock with the carbon fiber cargo box, the outbound landing workstation places the carbon fiber cargo box on the unloading and stacking conveyor line;

[0058] Step 9: The carbon fiber cartons are photographed and inspected on the unloading and stacking conveyor line. The carbon fiber cartons that meet the outbound process are sent to the stacking station, while the carbon fiber cartons that do not meet the outbound process are sent to the manual unloading outlet and transferred to the warehousing end for re-warehousing.
