Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology, and in particular to a workstation system and control method for an automated cutting and assembly production line for ship parts. Background Technology

[0002] With the increasing pursuit of larger and faster ship designs, unprecedented demands are being placed on the cutting and blanking of assembly components during hull construction, with the core challenge being the dual improvement of precision and efficiency. To meet the structural strength and hydrodynamic performance requirements of high-tonnage ships, hull components are becoming increasingly larger in size and their surface complexity is significantly increasing. This places unprecedentedly stringent demands on the machining precision and production efficiency of assembly components. Traditional processes such as flame cutting and plasma cutting, due to their large heat-affected zones, limited cutting speeds, and unstable edge forming quality, are no longer suitable for the demands of high-precision, batch cutting.

[0003] Against this backdrop, laser technology, with its superior cutting performance, has been increasingly widely used in shipbuilding as an advanced new processing medium. It has significantly improved the cutting accuracy and processing speed of complex hull parts, effectively meeting the needs of modern shipbuilding. However, while the high efficiency and precision advantages of laser cutting technology are fully realized in the cutting process, they have unexpectedly highlighted bottlenecks in subsequent processes: the sorting, arrangement, and allocation of the large number of parts cut quickly and precisely have not been simultaneously automated or intelligentized. This has led to a sharp increase in the workload of these highly manual processes, becoming a new challenge restricting overall production efficiency and process smoothness. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the present invention provides a workstation system for an automated cutting and sorting production line for ship parts. The workstation system includes a total of 8 workstations, namely, loading and unloading workstation, feeding buffer workstation, first cutting workstation, second cutting workstation, unloading buffer workstation, first automatic sorting workstation, second automatic sorting workstation, and manual replenishment workstation. The workstations are connected in the process by the form of cutting pallets carrying parts.

[0005] The loading and unloading stations are used for loading and unloading steel plates, surplus materials, and oversized parts. The feeding buffer station is used to buffer steel plates before the cutting station. The cutting station is used for high-precision cutting of steel plates and lifting and lowering of the cutting pallet. The unloading buffer station is used to buffer steel plates after the cutting station and before automatic sorting, and to handle warping of parts and waste materials on the cut steel plates. The automatic sorting station is used to automatically sort the parts after cutting. The manual sorting station is used to manually handle missed parts and cutting waste materials.

[0006] Optionally, the loading / unloading station, the feeding buffer station, and the unloading buffer station all include a conveyor roller bed and a transverse RGV trolley; the first cutting station and the second cutting station include a conveyor roller bed, a lifting mechanism, and a laser cutting machine; the first automatic sorting station includes a conveyor roller bed, a transverse RGV trolley, and an automatic sorting mechanism; the second automatic sorting station includes a conveyor roller bed, a lifting mechanism, and an automatic sorting mechanism; and the manual sorting station includes a conveyor roller bed.

[0007] Optionally, the first cutting station and the second cutting station are designed to run in parallel, and the first automatic sorting station and the second automatic sorting station are also designed to run in parallel.

[0008] This invention also provides a control method for an automated cutting and sorting production line for ship parts, including a steel plate sorting stage and a steel plate cutting and sorting stage based on the aforementioned workstation system; the steel plate sorting stage includes:

[0009] T1: The production management department will create an advance schedule based on the vessel delivery orders;

[0010] T2: Based on the preliminary schedule, the design department will draw up a cutting plan, the hull design will issue a cutting instruction, and the cutting task package will be formed in accordance with the principle of complete assembly of medium and large parts.

[0011] T3: The design department performs preliminary grouping of cutting task packages, taking into account the completeness of parts within the same flow pallet, and minimizing the need for pallet turnover at the line edge; the final result after the preliminary grouping of cutting task packages is divided into two categories: one is that the sorting does not need to be changed and is based on the default sorting; the other is that the cutting task packages are grouped into smaller cutting packages, and the order of the steel plates within the smaller cutting packages can be arbitrarily changed; the grouping results are written into the database and output to the manufacturing department.

[0012] T4: The supporting departments will formulate a procurement plan based on the preliminary schedule; based on the steel plate application submitted by the manufacturing department, they will develop a preliminary material sorting plan and scheme, sort and cache the procured steel plates according to the preliminary sorting results, and at the same time compile and provide a steel plate sequence list to the manufacturing department.

[0013] T5: The manufacturing department, based on the advance schedule, generates a steel plate cutting plan and submits a steel plate application; at the same time, it imports the cutting instructions provided by the design department and the steel plate sequence list provided by the supporting departments into the developed fine-ordering tool for cutting packages. By integrating the cycle time of each station on the automated cutting and matching production line for ship parts and the already conveyed process, the cutting task packages or small cutting packages are finely ordered to make production smooth and efficient and guide the loading of steel plates.

[0014] Optionally, the steel plate cutting and arrangement stage specifically includes:

[0015] S1: After the steel plates arrive, pre-processing of the steel plates will be carried out according to the pre-processing plan arranged by the manufacturing department based on the advance schedule.

[0017] S3: The steel plates with marked lines and printed characters are sorted and piled up in the transverse span according to the refined sorting results;

[0018] S4: The steel plates to be cut are transported by flatbed truck to the automated cutting and sorting production line for ship parts and unloaded.

[0019] S5: The completed cutting instructions and steel plate sequence list are input into the production line control system in advance. After the control system judges whether the reception and storage are normal, it stores them in the control system database.

[0020] Optionally, the steel plate cutting and arrangement stage further includes the following steps:

[0021] S6: Manually check whether there is an empty cutting pallet at the loading and unloading station. If there is an empty cutting pallet, first scan the QR code on the steel plate with a PDA. The central control system will check whether the loading sequence is in line with the order and whether the cutting / sorting instructions are called normally. After confirmation, manually press the button to stop the roller conveyor from moving and hoist the steel plate onto the cutting pallet. After hoisting is completed, press the complete button.

[0022] S7: The central control system determines whether the feeding buffer station has the conditions for lateral movement. After confirming that lateral movement is possible, it starts the lateral movement and determines whether it has reached the correct position.

[0023] S8: There are two cutting stations, both with an up-and-down lifting structure. Cutting operations at the top do not affect the transportation of the cutting pallet at the bottom, ensuring the production line operates at a steady pace. The central control system automatically determines whether to transport the cutting pallet from the feeding buffer station to the first or second cutting station.

[0024] S9: The lifting mechanism lifts the cutting tray to the working plane, where the laser cutting machine cuts the parts according to the cutting instructions;

[0025] S10: After cutting is completed, the central control system determines whether the conditions for removal are met. If confirmed, the lifting mechanism lowers and the roller conveyor moves the cutting pallet horizontally to the discharge buffer station.

[0026] S11: The central control system sends the signal that the cutting pallet is in place to the manual PAD. The worker presses the door opening button to enter the unloading buffer station, handles factors that affect automatic sorting such as warped or tilted parts, and exits the unloading buffer station after handling. The central control system receives the completion signal.

[0027] Optionally, the steel plate cutting and arrangement stage further includes the following steps:

[0028] S12: There are two automatic sorting stations, two of which are vertical lifting structures. The upper sorting operation does not affect the transportation of the cutting pallets below, ensuring the production line's rhythmic production. The central control system automatically determines whether to transport the cutting pallets from the feeding buffer station to the first or second automatic sorting station.

[0029] S13: The lifting mechanism lifts the cutting pallet to the working plane, and the sorting gantry automatically sorts the pallets according to the cutting instructions;

[0030] S14: After automatic sorting is completed, the central control system determines whether the conditions for removal are met. If confirmed, the lifting mechanism lowers and the roller conveyor moves the cutting pallet horizontally to the manual sorting station.

[0031] S15: The central control system instructs the manual to pick up the parts that need to be picked up. The manual picks up the parts and enters the information into the system. After the picking is completed, the waste materials are removed and the operation is confirmed to be completed.

[0032] S16: The central control system determines whether there is space at the loading / unloading station. If there is space, the cutting pallet is moved to the loading / unloading station.

[0033] S17: Oversized parts are manually sorted out of the production line, and the operation is confirmed to be complete;

[0034] S18: Repeat S1-S17 above, and continue the operation until one cutting task package is completed.

[0035] As described above, this invention provides a workstation system and control method for an automated cutting and fitting production line for ship parts. This system combines cutting and fitting, connecting the cutting process with the fitting station via a conveyor roller conveyor. Cutting, fitting, and conveying are all automated on the production line, effectively reducing manual labor, improving the accuracy and overall efficiency of parts cutting and blanking, and meeting the requirements of subsequent assembly and welding. Simultaneously, at the control method level, steel plate sorting is introduced before the cutting process begins. This pre-sorting mechanism aims to ensure that every pallet of parts produced is complete and intact, avoiding production stoppages due to missing parts. By ensuring that the pallets of parts between sections are complete, the production line achieves rhythmic production, improving production efficiency. This results in complete pallet parts, reduced pallet transfer load, and smooth production line rhythm, providing strong technical support for improving shipbuilding efficiency and product quality.

The cutting, sorting, and conveying stations in the production line are all completed automatically, effectively reducing the manual load, improving the accuracy and overall efficiency of parts cutting and blanking, and meeting the needs of subsequent assembly and welding.

[0052] Based on the aforementioned workstation system, this invention addresses the automated cutting and assembly process of ship parts and also proposes a control method suitable for automated cutting and assembly production lines for ship parts, such as... Figures 2 to 6 As shown, it includes two parts: the initial steel plate sorting and the actual production on the production line, in order to achieve the goals of complete pallet parts, reduced pallet transfer load, and smooth production line cycle.

[0053] The above-mentioned control method applicable to automated cutting and sorting production lines for ship parts is divided into a steel plate sorting stage and a steel plate cutting and sorting stage. The steel plate sorting stage specifically includes:

The final results after initial grouping of cutting task packages fall into two categories: one where no sorting changes are needed, and the other where the cutting task packages are grouped into smaller cutting packages, and the order of the steel plates within these smaller packages can be arbitrarily changed. The grouping results are written to the database and output to the manufacturing department.
