Description

Technical Field

[0001] This invention relates to the field of production equipment control technology, and in particular to an intelligent management system and method for the entire life cycle of rolls in a seamless steel pipe production line. Background Technology

[0002] Rolls are one of the important components in the production process of seamless steel pipes. The entire life cycle of rolls mainly includes three scenarios: roll processing, roll storage, and roll online production. For example, in a certain specification of seamless steel pipe production line, the roll diameter of a 6-stand three-roll continuous rolling mill is Φ710-660mm, the roll stand assembly is about 8t, and the assembly of a single roll is about 650kg. In order to avoid the production equipment running idle and to ensure the continuity and reliability of seamless steel pipe production, the roll stand assembly generally adopts the "one in use, one on standby, one in operation" mode. Therefore, normal production operation requires 18 sets of roll stands to be assembled, and 54 rolls are on standby.

[0003] Currently, in the three scenarios of roll processing, roll storage, and online roll production, rolls still require manual handling using overhead cranes for hoisting and transfer via cross-carts. Roll marking is achieved manually by printing steel stamps, and roll usage orders are manually filled out by human eyes. However, due to the inevitable fatigue of workers during long-term work, there are problems such as omissions and errors in the human eye reading process and errors and omissions in the filling out of usage orders. It is also inevitable that there will be problems of low efficiency and untimely reading and filling. Moreover, due to the inevitable fatigue of workers during long-term work, there are potential safety hazards for on-site workers in areas with heavy products and heavy equipment such as rolls. At the same time, this method has high labor costs and cannot meet the needs of the current construction of information-based and intelligent production lines, and is incompatible with the development needs of intelligent and unmanned operations. Summary of the Invention

[0004] To address some or all of the technical problems existing in the prior art, this invention provides an intelligent management system and method for the entire life cycle of rolls in a seamless steel pipe production line. This system enables intelligent connection and automated management of the rolls throughout their entire life cycle, improves roll processing efficiency, reduces manpower requirements, and meets the needs of informatization and intelligentization.

[0017] Furthermore, the aforementioned intelligent management system for the entire life cycle of seamless steel pipe production line rolls also includes a detection and tracking device, which is used to detect and track the transported rolls and roll frames.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The technical solutions provided in the embodiments of the present invention will be described in detail.

[0039] Firstly, as attached Figure 1 As shown, this embodiment of the invention provides an intelligent management system for the entire lifecycle of rolls in a seamless steel pipe production line. Its key feature is the ability to connect three areas—roll processing, roll storage, and online roll production—to achieve automatic transfer and storage of rolls and roll stands. The system includes: hoisting equipment 1, transfer equipment 2, calibration equipment 3, a first identification module 4, a second identification module 5, a first control module 6, and a second control module 7, wherein:

[0040] Lifting equipment 1 is installed in the roll processing area for lifting rolls; transfer equipment 2 is installed between the roll processing, roll storage, and roll online production areas, as well as outside the overall area formed by the three areas. Transfer equipment 2 is used to transfer rolls between the three areas or outside the overall area according to a preset route, or to transport the roll frame in the roll processing area to the roll storage area for storage according to a preset route; calibration equipment 3 is installed in the roll online production area for calibrating the produced rolls; a first identification module 4 is located at the entrance and exit of the roll processing, roll storage, and roll online production areas. The first identification module 4 is used to identify and read the information calibrated on the rolls by calibration equipment 3; a second identification module 5 is installed in the roll processing and roll storage areas. At the entrance and exit of the three areas of online roll production, the second identification module 5 is used to identify the information of the roll frame transferred by the transfer equipment 2; the first control module 6 is connected to the hoisting equipment 1 and the transfer equipment 2, and is used to control the hoisting equipment 1 to hoist the roll and to control the transfer equipment 2 to transfer the roll or roll frame. The first control module 6 is also used to receive the roll information identified by the first identification module 4 and the roll frame information identified by the second identification module 5; the second control module 7 is equipped with a warehouse management system 9 and a warehouse control system 10. The warehouse management system 9 is interactively connected to the first control module 6. The warehouse control system 10 can execute the instructions of the warehouse management system 9 and control the storage of the roll frame and roll in the roll storage area.

[0041] Therefore, the intelligent management system for the entire life cycle of rolls in a seamless steel pipe production line of the present invention realizes intelligent connection and automated management of the entire life cycle of rolls, improves roll processing efficiency, and reduces manpower requirements; the use of overhead cranes in the workshop is reduced through the transfer equipment 2; by connecting the three areas of roll production and storage, roll processing, roll storage and online roll production, real-time interaction and precise management of roll and roll stand information are realized under the action of calibration equipment 3, first identification module 4, second identification module 5, first control module 6 and second control module 7, and automatic transfer and storage of rolls and roll stands are achieved, meeting the needs of information-based and intelligent production line construction.

[0042] In some optional implementations of this embodiment, the hoisting equipment 1 includes a crane; the transfer equipment 2 includes an AGV trolley; the preset route includes a fixed route that the AGV trolley can match and identify, and the fixed route is fixed on the ground between the three areas of roll processing, roll storage and roll online production, as well as on the ground of the overall area formed by the three areas.

[0043] For example, a fixed route guides the AGV vehicle to travel along a preset route, for example by magnetic strips, QR codes, or landmarks.

[0044] This setup utilizes identifiable physical markers (such as magnetic strips, QR code strips, and laser reflective strips) for the AGV, precisely matching them with the AGV's navigation and identification module. This ensures accurate positioning of the transfer path and supports controllable trajectory of the rolls / roll mill frame during cross-regional transfers. The route layout is jointly controlled with the transfer instruction planning of the first control module 6 and the warehouse scheduling of the second control module 7. Through preset route nodes (such as area boundaries and equipment docking points), the AGV can accurately stop at the operation point of the hoisting equipment 1, the entrance to the warehouse area, and the roll changing point in the online production area, ensuring seamless connection between cross-regional transfers and processing, storage, and production processes.

[0045] like Figure 2 As shown, in Figure 2 The direction indicated by the middle arrow is the travel direction of the AGV. To improve transfer efficiency, in actual application, there are also intermediate warehouses for offline rolls (No. 1) and processed rolls (No. 2) in the roll processing area. To improve the transfer efficiency of the AGV, the rolls and roll frames are transferred along the optimal route with the shortest distance during the transfer process. The fixed lines on the ground between the three areas of roll processing, roll storage, and roll online production, as well as the ground of the overall area formed by the three areas, are interconnected.

[0046] This setup, by using the AGV as a transport vehicle for the rolling mill, and interacting in real time with the first control module 6 and the second control module 7, allows the AGV to receive transfer instructions from the first control module 6 and the second control module 7, while simultaneously providing feedback on its own position, load status, and material identification results. This enables the scheduling of the other AGVs, ensuring that the transferred materials are accurately matched with production and warehousing needs by verifying the information of the rolling mill and the rolling mill frame during the transfer process. Furthermore, the transfer rhythm can be dynamically adjusted according to the operating status of the hoisting equipment 1 and the calibration equipment 3, achieving a smooth connection between the processing, warehousing, and production stages.

[0047] In order to further and comprehensively inspect the transported rolls and roll stand, an inspection and tracking device 8 is also provided in this embodiment of the invention. The inspection and tracking device 8 is used to inspect and track the transported rolls and roll stand.

[0048] This setup, through the deployment of detection and tracking devices 8, collects real-time physical status (such as position coordinates, transfer posture, and whether the rolls / roll stands are in place) and flow data (such as entry / exit time and dwell time) of the rolls / roll stands, forming a dynamic data chain for material flow. The tracking range covers the entire process of workstation flow within the roll processing area, cross-area transfer paths (processing area to storage area, storage area to online production area), and storage scheduling within the storage area, precisely matching the flow requirements of each stage of the roll's lifecycle. The detection and tracking data is transmitted in real-time to the first control module 6 and the second control module 7, providing a basis for path adjustments of the transfer equipment 2 (such as avoidance and priority scheduling), warehouse location allocation in the storage management system 9, and roll change preparation in the online production area. This achieves closed-loop linkage control of "detection-tracking-control," ensuring the visualization and controllability of the roll and roll stand transfer process, further ensuring the safety of roll and roll stand transfer.

[0049] In some optional implementations, the detection equipment includes multiple sets of photoelectric switches and multiple sets of proximity switches, which are distributed along a preset route of the transfer equipment 2.

[0050] Photoelectric switches are used to detect the presence and status of rolls / roll frames and the signal of passage, accurately identifying the trigger signals of materials entering / leaving specific areas (such as processing area workstations, storage area entrances, and transfer path nodes); long-stroke proximity switches are used to capture the position coordinates and movement status of materials during long-distance transfer, adapting to the large size characteristics of rolls / frames (weighing less than 8t and several meters in length), and realizing long-distance non-contact detection.

[0051] In some optional implementations of this embodiment, multiple sets of photoelectric switches and multiple sets of proximity switches are densely deployed along key nodes (such as area boundaries, equipment docking points, and path corners) of a preset route, forming a "point-line-surface" combined detection network. This network covers the entire path of internal circulation within the roll processing area, cross-regional transfer (from processing area to storage area, from storage area to online production area), and external scheduling, accurately matching the running trajectory of the AGV trolley and other transfer equipment 2. Simultaneously, the detection signals are transmitted to the material detection and tracking unit in real time, processed, and synchronized to the first control module 6 and the second control module 7. This provides real-time data support for the start-stop control, path correction (such as obstacle avoidance), and storage scheduling (such as pre-preparing storage locations) of the transfer equipment 2, enhancing the controllability and response speed of the roll's entire life cycle circulation process.

[0052] Meanwhile, by using multiple sets of photoelectric switches and multiple sets of proximity switches distributed along the preset route of the transfer equipment 2, the transfer rolls and roll frames can be detected from all directions by the multiple sets of photoelectric switches and multiple sets of proximity switches. This allows for relatively accurate positioning of the transfer rolls and roll frames, preventing malfunctions during the transfer process that could cause collisions with other AGVs traveling along the preset route.

[0053] In some optional implementations of the present invention, the calibration device 3 includes a laser QR code printing system, which prints a laser QR code containing roll information on the non-working surface of the roll.

[0054] In some optional implementations of this embodiment, a unique laser QR code containing core information about the entire life cycle of the roll is permanently printed on the non-working surface of the roll (such as the roll neck, end face, and other areas not involved in rolling). The laser QR code integrates the roll's inherent parameters (model, specifications, material), processing data (grinding amount, assembly accuracy), calibration results (dimensional tolerances, compatible frame models), and circulation records (number of uses, maintenance history). At the same time, printing on the non-working surface avoids wear or contamination of the QR code during rolling, ensuring that it can be stably read by the first identification module 4, the second identification module 5, and the auxiliary identification device of the transfer equipment 2 throughout the entire process of roll processing, warehousing, and online production, thus ensuring the full life cycle traceability of the identity information.

[0055] To provide accurate identity verification for roll storage, outbound scheduling, and online adaptation, the laser QR code assignment process is completed simultaneously with the accuracy detection of the calibration device 3. After the QR code information is generated, it is uploaded to the first control module 6 in real time and associated with the warehouse management system 9 of the second control module 7 to achieve one-to-one binding of "physical roll - digital information".

[0056] In some alternative implementations, the first control module 6 includes a MES system.

[0057] In some optional implementations, the roll processing area is equipped with a truss, a truss intelligent crane, a press, a roll lathe, a heater, and a calibration station. The press is used to disassemble the continuous rolling mill stand into two parts: rolls and the stand. The roll lathe is used to grind the rolls. The heater is used for bearing assembly. The calibration station is used to calibrate the roll stand and return the calibration value to the first control module 6 of the online production line.

[0058] For example, such as Figure 3 As shown, the following example illustrates the full lifecycle management of rolls (with bearing housings) and stands in a seamless steel pipe production line. Using the intelligent management system for the entire lifecycle of rolls in a seamless steel pipe production line provided in this embodiment of the invention, the system manages the entire lifecycle from continuous rolling mill stand disassembly to roll (with bearing housing) repair, scrapping, and assembly and calibration of the stand with new rolls and bearings. This includes:

[0059] Starting with the continuous rolling mill stand, the process is divided into two branches: rolls (with bearing housings) and mill stand processing. For rolls (with bearing housings), the processing flow is divided into different procedures based on the relationship between the throat diameter and the minimum throat diameter. Specifically, the process includes: determining the relationship between the throat diameter and the minimum throat diameter; if the throat diameter is greater than or equal to the minimum throat diameter, the rolls first undergo "fatigue layer removal (roll lathe)". After removing the fatigue layer, if the throat diameter is still greater than or equal to the minimum throat diameter, the rolls proceed to the "grooving (roll lathe)" process to complete the roll processing. If the throat diameter is less than or equal to the minimum throat diameter, the process is further subdivided into "bearing housing disassembly". Subsequently, depending on whether the bearing is qualified, the process is determined to either "replace the roll and assemble" and then reprocess the groove, or to "scrap the roll". This reflects the roll processing line's repair, scrapping determination, and reassembly of rolls. For the frame processing, the frame branches are combined with "new rolls" and "new bearings." After "heating (new bearings)," they enter the "roll frame assembly." Then, through the "calibration" stage, corresponding to the invention's "calibration station used to determine whether the rolls are suitable for continued operation and to calibrate the roll frame, returning the calibration values ​​to the MES system," a "finished frame" is ultimately formed. This is the pre-process of the roll processing line producing qualified roll frames, which are then stored in the roll intelligent library and used in production. Regarding the determination of bearing quality in the process, qualified bearings can be "retained" and enter the heating and assembly stages, while unqualified bearings are "scrapped." This reflects the roll processing line's management of bearing reuse and replacement, thereby ensuring the quality of roll frame assembly and serving the online use stage of seamless steel pipe production.

[0060] Therefore, by adopting the intelligent management system for the entire life cycle of seamless steel pipe production line rolls provided in this embodiment of the invention, a complete closed loop is achieved, from the dismantling of the continuous rolling mill stand to the repair and scrapping of the rolls (with bearing seats), and the assembly and calibration of the stand with new rolls and bearings. This improves management efficiency and meets the needs of information-based and intelligent production line construction.

[0061] refer to Figure 1, Figure 2 and Figure 4 The principle of the intelligent management system for the entire life cycle of rolls in a seamless steel pipe production line provided in this embodiment of the invention includes:

[0062] By constructing a physical transfer network from online roll production to roll storage and processing using hoisting equipment 1 and transfer equipment 2, the inefficient methods of manual hoisting and cross-carriage transport are eliminated. This allows rolls to automatically flow between processing, storage, and usage scenarios, achieving a complete physical connection between roll off-line, repair / processing, storage, and online operation. This fundamentally solves the problems of fatigue and high labor costs that are inevitable during long-term manual work, and also addresses the issues of low efficiency and safety hazards in cross-scenario and cross-regional roll transfer. Calibration equipment 3 calibrates each roll with a unique code, and a first identification module 4 and a second identification module 5 are set up in different areas of roll processing, roll storage, and online roll production to identify the code. This allows rolls to be identified through the first identification module 4 and the second identification module 5 during transfer, obtaining the corresponding roll information and avoiding problems during transfer. To address the issue of chaotic roll transportation, the hoisting equipment 1 and transfer equipment 2 are connected to the first control module 6 to control the transfer of rolls and roll frames, thus forming a closed-loop control system. This solves the problems of omissions and errors in the existing technology when reading data by eye, and errors and omissions in filling out work orders. Through the coordinated operation of the warehouse management system 9 and warehouse control system in the second control module 7 with the first control module 6, the transfer and storage of rolls and roll frames are completed, realizing the coordination of demand-storage-supply. The warehouse management system 9 connects to the first control module 6 to obtain roll demand, and the warehouse control system 10 schedules the automatic storage and retrieval of equipment in the warehouse. Combined with the identification of the first identification module 4 and the second identification module 5, the roll frame assembly meets the requirements of "one in use, one on standby, one in operation, and one mode" while achieving intelligent scheduling and on-demand supply, thereby better matching the real-time needs of the production line.

[0063] Therefore, the seamless steel pipe production line roll full life cycle intelligent management system provided by this invention has an intelligent roll storage system that can store 80-100 sets of roll stands. The identification module at the entrance can quickly confirm the roll information and return the stored information to the MES system in real time to ensure the accuracy of the inventory information. The roll processing line has an intermediate storage room 1 for off-line rolls and an intermediate storage room 2 for processed rolls. AGVs transport rolls in an orderly manner between the intermediate storage room and the online production area and intelligent storage room, improving the transfer efficiency. The press of the roll processing line splits the continuous rolling mill stand into rolls and stands. The roll lathe precisely grinds the rolls, the heater ensures the quality of bearing assembly, and the calibration station calibrates the roll stand and returns the calibration value to the MES system to ensure that the processed rolls meet the production requirements. The warehouse management system 9 interacts with the first control module 6 in real time, and the warehouse control system 10 executes the storage scheduling instructions of the warehouse management system 9, realizing efficient management of the intelligent roll warehouse. After the laser QR code is printed on the roll processing line, it runs through the entire life cycle. The first identification module 4 and the second identification module 5 ensure the accurate transportation of the roll in each link. By taking the first control module 6 as the control center and coordinating with the second control module 7, the data of each link of the physical flow, information identification, processing and storage of the roll are linked. From the roll off the line and being coded, information such as processing parameters, storage location and online usage status are exchanged in real time. This allows the production, equipment and storage departments corresponding to the three areas of roll processing, roll storage and roll online production to communicate with each other, realize the management of the entire life cycle of the roll, improve the efficiency of roll processing, reduce the demand for manpower and meet the needs of information and intelligent production line construction.

[0064] Secondly, such as Figure 5 As shown, this embodiment of the invention also provides a method for intelligent management of the entire life cycle of rolls in a seamless steel pipe production line, the method comprising the following steps S100-S400:

[0065] Step S100: Lay out a pre-set route between the three areas of roll processing, roll storage, and roll online production, as well as outside the overall area formed by the three areas;

[0066] For example, between the roll processing area, the roll storage area, and the roll online production area, as well as around the entire perimeter of the three areas, a pre-set route adapted to transfer equipment (such as AGV trolleys and intelligent cranes) is planned and laid out to form a physical flow network covering the entire cycle of roll "processing → storage → online production". The pre-set route includes workstation connection sections within the area, cross-area transfer sections, and peripheral scheduling sections, thereby meeting the automated transfer path requirements of rolls and roll stands.

[0067] Step S200: Set up a first identification module and a second identification module at the entrance of the roll storage area and the roll online production area, as well as at the entrance and exit of the three areas of roll processing, roll storage and roll online production.

[0068] In some optional implementations, a first identification module is deployed at the entrance of the roll storage area and the entrance of the roll online production area to identify the identity information of the rolls entering the area. A second identification module is deployed simultaneously at the entrance and exit of the three areas of roll processing, roll storage and roll online production to identify the inherent information (such as model and batch) of the roll frames transported by the transfer equipment.

[0069] Step S300: Transfer the roll mill frame and the calibrated rolls along the laid preset line;

[0070] The old rolls replaced in the online production area are hoisted to the temporary storage position by the hoisting equipment and then transferred to the roll processing area by the transfer equipment along the preset route. The roll stands that have been processed in the roll processing area are transferred to the roll storage area by the transfer equipment along the preset route. According to the online production needs, the roll storage area uses the transfer equipment to transfer the qualified rolls calibrated by the calibration equipment to the online production area along the preset route, realizing the fully automated flow of "offline → processing → storage → online".

[0071] Step S400: After the first identification module and the second identification module identify the rolls or roll frame being transported along the preset route, they transmit the identified information to the first control module and the second control module. The first control module and the second control module work together to control the roll frame and the rolls to transport and store them.

[0072] After the first identification module identifies the transfer roll, it transmits its calibration information and identity information to the first control module. After the second identification module identifies the transfer roll stand, it transmits its information to the second control module. Based on the identification information, the first control module controls the transfer equipment to adjust the transfer path and rhythm, so as to achieve precise connection between the roll and the processing and production process. The second control module receives the interactive information from the first control module through the warehouse management system, and combines it with the roll stand identification data. The warehouse control system then executes storage instructions (such as storage location allocation and inbound / outbound scheduling), ultimately realizing intelligent transfer and precise storage of the roll and stand throughout their entire life cycle.

[0073] The present invention provides an intelligent management method for the entire life cycle of rolls in a seamless steel pipe production line. This method realizes intelligent connection and automated management of rolls throughout their entire life cycle, improves roll processing efficiency, reduces manpower requirements, enables real-time interaction and precise management of information on rolls and roll stands, and achieves automatic transfer and storage of rolls and roll stands, thus meeting the needs of information-based and intelligent production line construction.
