Description

Technical Field

[0001] The present invention belongs to the technical field of flexible manufacturing, and particularly relates to an integrated flexible manufacturing system for a production workshop line library and a manufacturing method for electric heating tubes. Background Art

[0002] The electric heating tube has a relatively complex processing technology, especially the heat treatment process. Due to the differences in specific products, there are significant differences in the sequence of heat treatment, and some products have multiple heat treatment phenomena. As a result, the processing technology of the electric heating tube has a serious problem of back-and-forth intersection, leading to frequent logistics backtracking, which in turn affects the smoothness of the workshop logistics and increases the difficulty of workshop layout and work-in-progress management. Therefore, in view of the design scenario of integrating multiple products, multiple processes and multiple logistics equipment in the electric heating tube manufacturing workshop, an integrated flexible manufacturing system and method for the line library are proposed. Summary of the Invention

[0003] Aiming at the above problems existing in the prior art, the purpose of the present invention is to provide an integrated flexible manufacturing system for a production workshop line library and a manufacturing method for electric heating tubes, which realizes the integration and automation of the production and storage processes and improves the production and logistics efficiency.

[0004] The present invention provides the following technical solutions:

[0005] An integrated flexible manufacturing system for a production workshop line library, based on a software system for the integrated flexible manufacturing system of the line library, an AGV control system, a vertical library control system and an enterprise resource management system; including a group of production lines, a work-in-progress shuttle car storage system and AGV cars, and each production line is configured with a corresponding production line side material calling device; the software system of the integrated flexible manufacturing system of the line library adopts a three-layer system architecture, including a production execution system and a warehousing management system, which connects the enterprise resource management system upward and is compatible with the AGV control system, the vertical library control system, each production line and sensor monitoring equipment downward, and realizes the transmission of production plan designation and feedback, production line material request and feedback, inbound and outbound instructions and handling instructions; the production line side material calling device can realize the binding of the material basket and the storage location, and send an inbound instruction to the warehousing management system; the work-in-progress shuttle car storage system receives the instruction of the warehousing management system and completes the inbound and outbound tasks of the material basket carrying the products at each processing stage; the AGV car is used to transfer the work-in-progress between various production lines and the work-in-progress shuttle car storage system.

[0006] Furthermore, the production line side material calling device has a code scanning function. After scanning the two-dimensional code on the corresponding distribution material basket, it binds the product information and the storage quantity; scans the two-dimensional code on the storage location, binds the material parts in the material basket with the storage location, and sends an inbound instruction to the warehousing management system. The warehousing management system sequentially sends a handling task request instruction to the AGV control system according to the task list, and the AGV control system responds to the task and schedules the AGV car to carry the material parts to the designated location.

[0007] Further, the AGV control system includes AGV management and AGV scheduling, which are used to receive the handling instructions and tasks from the warehouse management system and provide task feedback.

[0008] Further, the vertical warehouse control system includes three-dimensional warehouse control and conveyor line control, which receive the inbound and outbound instruction tasks from the warehouse management system and provide task feedback.

[0009] The method for manufacturing electric heating tubes based on the integrated flexible manufacturing system of the production workshop line warehouse is characterized by including the steps of empty tube warehousing of electric heating tubes, powder adding treatment of electric heating tubes, and heat treatment of electric heating tubes. The specific steps are as follows:

[0010] S1. Empty tube warehousing of electric heating tubes: Use an AGV trolley to carry out inbound handling of the empty tubes of electric heating tubes, and inspect the inbound empty tubes of electric heating tubes.

[0011] S2. Powder adding treatment of electric heating tubes: Use an AGV trolley to carry the empty tubes of electric heating tubes into the powder adding production line for powder adding treatment, and then store the electric heating tubes after powder adding.

[0012] S3. Heat treatment of electric heating tubes: including heat treatment of empty tubes and heat treatment of externally processed nickel-plated electric heating tubes.

[0013] Further, the specific process of the empty tube warehousing of electric heating tubes is as follows:

[0014] S1.1. When the empty tubes of electric heating tubes are unloaded from the production line, manually operate the material calling device beside the production line to scan the QR code on the material frame, and input product information data for material information maintenance.

[0015] S1.2. Manually operate the material calling device beside the production line to scan the QR code on the storage location, bind the material with the storage location, and click to generate an empty tube inbound handling instruction after confirmation.

[0016] S1.3. The material calling device system beside the production line sends an inbound instruction to the warehouse management system, and the warehouse management system sequentially sends a handling task request instruction to the AGV control system according to the task list. The AGV control system responds to the task and schedules the AGV trolley to carry the material to the specified location.

[0017] S1.4. After the AGV trolley completes the handling task, place the material frame filled with empty tubes of electric heating tubes on the inbound conveyor line of the electric heating tube three-dimensional warehouse. After shape inspection, the three-dimensional warehouse control system schedules the corresponding shuttle car to complete the inbound operation of the empty tube material frame of electric heating tubes.

[0018] S1.5. When the shape inspection of the material box fails, the conveyor line automatically transports it to the manual processing section. After waiting for manual verification and processing, it is re-transported to the inbound conveyor line. After the shape inspection is completed again, the shuttle car completes the operation of storing the empty tube material box of the electric heating tube in the warehouse.

[0019] Furthermore, the specific process of adding powder to the electric heating tube is as follows:

[0020] S2.1. The warehouse management system generates a corresponding outbound instruction according to the production task from the enterprise resource management system, and issues an execution instruction containing the material warehouse location information to the electric heating tube stereoscopic warehouse control system.

[0021] S2.2. The stereoscopic warehouse control system schedules an idle shuttle car to perform the outbound operation. The shuttle car transports the electric heating tube at the target warehouse location to the outbound port and waits for the next transportation by the AGV car.

[0022] S2.3. After receiving the outbound instruction, the AGV control system schedules an idle AGV car to transport the electric heating tube material box to the receiving station of the powder adding production line for powder adding. Among them, the powder adding uses the mode of picking materials piecemeal for feeding, and the worker uses a trolley to transport the electric heating tube to the material placing rack of the powder adding equipment.

[0023] Furthermore, in step S3, the specific process of heat treatment of the empty tube is as follows:

[0024] When directly heat-treating the empty tube, the warehouse management system generates a corresponding outbound instruction according to the production task from the enterprise resource management system, and issues an execution instruction containing the material warehouse location information to the electric heating tube stereoscopic warehouse control system. The stereoscopic warehouse control system schedules an idle shuttle car to perform the outbound operation. The shuttle car transports the electric heating tube at the target warehouse location to the outbound port and waits for the next transportation by the AGV car.

[0025] Furthermore, in step S3, the specific process of heat treatment of the externally processed nickel-plated electric heating tube is as follows:

[0026] The heat treatment of the externally processed nickel-plated electric heating tube is divided into two parts. One part is the outsourcing operation of the empty tube, and the other part is the heat treatment operation of the externally processed tube. According to the outsourcing task from the enterprise resource management system, the warehouse management system generates a corresponding outbound instruction for the electric heating tube. At the same time, after receiving the outbound instruction, the AGV control system schedules an idle AGV car to transport the electric heating tube material box to the receiving and shipping platform and waits for unpacking and loading for shipment.

[0027] By adopting the above technology, compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] In the present invention, through the connection of the integrated flexible manufacturing system software system of the wire storage, a logistics connection is established between the in-process shuttle car storage system and various production lines through AGVs. In the integrated flexible manufacturing system of the wire storage, when the production line initiates a material distribution request, after receiving the request, the warehouse management system immediately triggers relevant instructions, schedules the shuttle car to complete the outbound operation, and at the same time schedules the idle AGV cars to perform the material handling operation. This process is completed by intelligent logistics equipment, realizing unmanned operation throughout the process. At the same time, for the in-process storage shuttle car storage system, through the warehouse management system in the integrated flexible manufacturing system software system, refined management of the storage locations is achieved. Managers can know the status of all in-process products in the warehouse through the software interface, monitor the in-process products in real time, and can also assist in formulating reasonable production plans to balance production.

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specification drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] On the contrary, the present invention covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present invention defined by the claims. Further, in order to enable the public to have a better understanding of the present invention, in the following detailed description of the present invention, some specific details are described in detail. Those skilled in the art can fully understand the present invention without the description of these details.

[0037] Please refer to Figure 1-6, The integrated flexible manufacturing system of the production workshop line and warehouse is a unitized production center composed of several CNC centers, industrial robots, material transfer equipment, handling robots, and storage equipment facilities, with the flexibility of multi-product processing and the adaptability of multi-process production. The flexible manufacturing unit has functions such as automated processing, material transfer and storage, and automatic inspection and monitoring. The specific function descriptions are as follows:

[0038] 1) Automated processing function: In the FMC, there are equipment for completing automated processing, such as CNC, numerically controlled lathes, combined machine tools, etc. These automated devices can be controlled by a computer system, which can monitor the processing progress in real time and complete the processing operations.

[0039] 2) Material transfer and storage function: This function is the significant difference between the PMC and a single CNC or machine tool. The PMC uses an automatic handling cart to complete the handling of materials, tools, and finished products between the operating equipment, and then docks with the stereoscopic warehouse for storage operations.

[0040] 3) Automatic inspection and monitoring function: The FMC has a unified control terminal, which can monitor the tool status, product processing progress, workpiece status, and equipment protection monitoring in real time.

[0041] The integrated flexible manufacturing system of the production workshop line and warehouse seamlessly connects each electric heating tube production line and the shuttle car automated stereoscopic warehouse through the AGV handling system, subverting the traditional manual operation mode that separates the production and storage links, and realizing the integration and automation of the production and storage processes. Figure 2 It is a schematic diagram of the integrated flexible manufacturing system of the production workshop line and warehouse. In addition, the integrated flexible manufacturing system of the production workshop line and warehouse endows itself with the ability of automated management through the integration of the production link and the warehousing link.

[0042] The integrated flexible manufacturing system of the production workshop line and warehouse physically connects the previously separated warehousing system and production system through the AGV handling system, greatly improving the convenience of logistics and production speed. It is based on the software system of the integrated flexible manufacturing system of the production workshop line and warehouse, the AGV control system, the automated warehouse control system, and the enterprise resource management system; including various production lines, the in-process product shuttle car warehousing system, and AGV carts.

[0043] Specifically, the integrated flexible manufacturing system of the production workshop line and warehouse can better carry out information interaction by using the software system of the integrated flexible manufacturing system of the production workshop line and warehouse, and at the same time form information integration between subsystems. The software system of the integrated flexible manufacturing system of the production workshop line and warehouse adopts a three-layer system architecture, including a production execution system, a warehousing management system, etc., connecting upward to the enterprise resource management system, etc., and at the same time being downward compatible with the AGV control system, the automated warehouse control system, various automated production lines, and sensor monitoring equipment, etc.

[0044] Specifically, each in-line material calling device has a QR code scanning function. After scanning the QR code of the corresponding distribution material basket, it binds the product information and storage quantity. Then it scans the QR code on the storage location to bind the material parts in the basket with the storage location, and sends an inbound instruction to the warehousing information system. The warehousing information system sequentially sends handling task request instructions to the AGV control system according to the task list, and the AGV control system responds to the task and schedules the AGV to carry the material parts to the specified location.

[0045] Specifically, the in-process shuttle car warehousing system receives instructions from the warehousing management system and completes the inbound and outbound tasks of the material baskets carrying the in-process electric heating tubes at each stage.

[0046] Specifically, the AGV car transfers the in-process products between various production lines and the in-process shuttle car warehousing system.

[0047] Specifically, the AGV control system includes AGV management and AGV scheduling, which is used to receive the handling instructions and tasks from the warehousing management system and give task feedback.

[0048] Specifically, the vertical warehouse control system includes vertical warehouse control and conveyor line control, which receives the inbound and outbound instruction tasks from the warehousing management system and gives task feedback.

[0049] Applying the system of this embodiment to the manufacture of electric heating tubes includes the inbound of empty electric heating tubes, the powder adding process of electric heating tubes, and the heat treatment of electric heating tubes; the specific process is as follows:

[0050] Inbound of empty electric heating tubes: When the empty electric heating tubes come off the production line, an operator manually operates the in-line material calling device to scan the QR code on the material basket, inputs data such as the product drawing number and storage quantity to maintain the material part information. Then the operator manually operates the in-line material calling device to scan the QR code on the storage location to bind the material parts with the storage location. After confirmation, click to generate a handling instruction for inbound of empty tubes. The in-line material calling device system will send an inbound instruction to the warehousing management system. The warehousing management system sequentially sends handling task request instructions to the AGV control system according to the task list. The AGV control system responds to the task and schedules the AGV to carry the material parts to the specified location. After the AGV completes the handling task, it places the material basket filled with empty electric heating tubes on the inbound conveyor line of the electric heating tube vertical warehouse. After the shape inspection is completed, the vertical warehouse control system schedules the corresponding shuttle car to complete the inbound operation of the material basket of empty electric heating tubes. If the shape inspection of the material basket fails, the conveyor line will automatically convey it to the manual processing section. After waiting for manual verification and processing, it is re-conveyed to the inbound conveyor line. After the shape inspection is completed again, the shuttle car will complete the inbound operation of the material basket of empty electric heating tubes.

[0051] Powder adding process for electric heating tubes: When powder adding operation is required for electric heating tubes, the warehouse management system generates corresponding outbound instructions according to the production tasks from the enterprise resource management system, and issues the execution instructions containing material storage location information to the control system of the electric heating tube automated storage and retrieval system. The control system of the automated storage and retrieval system schedules idle shuttle cars for outbound operations. The shuttle cars transport the electric heating tubes at the target storage locations to the outbound ports, waiting for the next handling by the AGV. After receiving the outbound instructions, the AGV control system schedules idle AGVs to transport the electric heating tube frames to the receiving stations of the powder adding production line. Powder adding is carried out in the mode of picking and feeding in pieces. Employees use trolleys to transport the electric heating tubes to the material placing racks of the powder adding equipment.

[0052] The electric heating tubes after powder adding still need to be stored in the in-process product shuttle car storage system. The process is similar to the inbound process of empty electric heating tubes.

[0053] Heat treatment of electric heating tubes: The heat treatment process of electric heating tubes includes two categories: heat treatment of empty tubes and heat treatment of externally processed nickel-plated electric heating tubes. When directly heat treating empty tubes, the warehouse management system generates corresponding outbound instructions according to the production tasks from the enterprise resource management system, and issues the execution instructions containing material storage location information to the control system of the electric heating tube automated storage and retrieval system. The control system of the automated storage and retrieval system schedules idle shuttle cars for outbound operations. The shuttle cars transport the electric heating tubes at the target storage locations to the outbound ports, waiting for the next handling by the AGV. The heat treatment of externally processed nickel-plated electric heating tubes is divided into two parts. One part is the outsourcing operation of empty tubes, and the other part is the heat treatment operation of externally processed tubes. According to the outsourcing tasks from the enterprise resource management system, the warehouse management system generates corresponding outbound instructions for electric heating tubes. At the same time, after receiving the outbound instructions, the AGV control system schedules idle AGVs to transport the electric heating tube frames to the receiving and shipping platform, waiting for repackaging (converting the tube material frames into pallets) and loading for shipment.

[0054] The electric heating tubes after heat treatment still need to be stored in the in-process product shuttle car storage system. The process is similar to the inbound process of empty electric heating tubes.

[0055] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
