Description

Technical Field

[0001] The present application relates to the technical field of metal sheet processing, and in particular to a flying shear production line. Background Art

[0002] In the sheet metal processing industry, increasing automation in manufacturing is driving ever-increasing demands for production line efficiency. While existing flying shear lines can meet the needs of mass production to a certain extent, they still struggle with cleanliness and flatness. Furthermore, inadequate coordination between equipment leads to low overall production efficiency, making them unable to fully adapt to the pace of modern large-scale production. To address these issues, the industry has typically implemented a variety of measures. For example, high-pressure water jets combined with chemical cleaning agents are used to remove surface oil during the cleaning phase, but this method is prone to environmental pollution and consumes a lot of water. Tension control systems are added during the unwinding process to reduce sheet deformation, but this increases system complexity and cost. Multi-roller structures are often used for leveling machines, which effectively improve sheet surface quality but also present the problem of frequent maintenance. Continuous material feeding using belt conveyors is a common practice, but this can cause positional deviations, impacting quality control in subsequent processes. Finally, fixed racks are commonly used for stacking finished products, which lack flexibility and struggle to accommodate fluctuating product specifications.

[0003] Traditional flying shear production lines have a series of defects such as poor environmental performance, high operating costs, inconvenient maintenance, and low level of intelligence, which urgently need to be improved and perfected.

[0004] In view of the above-mentioned related technologies, a solution is now proposed. Summary of the Invention

[0013] Preferably, it further includes a feeding mechanism, which includes a feeding trolley and a feeding cover. A feeding cover is provided on the right side of the feeding trolley, and the feeding cover is rotatably connected to the unwinding mechanism.

[0014] By adopting the above scheme, a structural design including a loading trolley and a rotating connected loading cover is adopted, which realizes the stable connection and automatic control of the material conveying process: the rotating connection between the loading cover and the unwinding mechanism enables the cover to adjust the angle synchronously with the unwinding action, which not only ensures the positioning accuracy of the material roll but also avoids mechanical interference. The loading trolley forms a closed loading unit by integrating the cover, which effectively prevents material deviation and simplifies the loading and unloading process. Its technical principle is to compensate for the position deviation between equipment through the rotational freedom of the rotating pair, and at the same time use the movement function of the trolley to realize rapid positioning of materials, thereby improving the loading efficiency while reducing the impact of equipment operation, ensuring the reliability and coordination of material transmission during continuous production.

[0015] Preferably, it also includes a clamping mechanism, which includes a material receiving plate, a rotating shaft, a telescopic rod, a clamping platform and a clamping roller. A rotating shaft is provided on one side of the material receiving plate, a telescopic rod is provided below the material receiving plate, a clamping platform is provided on one side of the telescopic rod, and a clamping roller is provided inside the clamping platform.

[0016] By adopting the above scheme, a pinching mechanism scheme including a receiving plate, a rotating shaft, a telescopic rod, a pinching table and a pinching roller is adopted. The design realizes the coordinated control of precise material positioning and flexible transmission: the receiving plate provides horizontal angle adjustment capability through the rotating shaft, which can adapt to the centering requirements of materials of different sizes. The vertical telescopic movement of the telescopic rod and the linkage of the pinching table realize dynamic compensation of the pinching height. The pinching roller forms a controllable clamping force inside the pinching table to ensure that there is no slipping or deformation during the material transportation process. The technical principle is to match the material posture change through the rotational freedom of the rotating shaft, and use the linear displacement of the telescopic rod to adjust the distance between the pinching table and the receiving plate. At the same time, the rolling friction and pressure closed-loop control of the pinching roller ensure continuous and stable material transportation, thereby improving the pinching accuracy and adaptability while reducing the risk of equipment interference and enhancing the collaborative efficiency of multiple links in the production line.

[0017] Preferably, an NC sizing system is further included, which includes a laser rangefinder, a drive motor, a numerical control system, a flying shear and a data communication module. The drive motor is provided on one side of the laser rangefinder, the flying shear is provided on one side of the drive motor, the numerical control system is provided on one side of the flying shear, and the data communication module is provided inside the numerical control system.

[0018] By adopting the above solution, an NC fixed-length system solution including a laser rangefinder, a drive motor, a CNC system, a flying shear and a data communication module is adopted. The design realizes the collaborative operation of high-precision dynamic shearing and real-time data closed-loop control: the laser rangefinder monitors the material length in real time and transmits the signal to the CNC system through the data communication module. The drive motor accurately adjusts the displacement speed and shearing timing of the flying shear according to the CNC instructions, and the flying shear completes rapid cutting under the triggering of the synchronization signal; its technical principle is to use the non-contact high-precision detection capability of laser ranging to build a material length feedback mechanism, and realize the coordinated action of the drive motor and the flying shear through the algorithm analysis and instruction distribution of the CNC system. At the same time, the data communication module ensures the real-time and anti-interference performance of signal transmission between components, thereby improving the fixed-length shearing accuracy and production efficiency while reducing the need for manual intervention, ensuring the consistency of shearing length and process stability under complex working conditions.

[0019] Preferably, the cleaning device also includes an angle adjustment module and a mixing pump. An angle adjustment module is provided on both sides of the atomizing cleaning nozzle. One side of the angle adjustment module is connected to a mixing pump through a water pipe, and the atomizing cleaning nozzle is used to spray water containing a biodegradable agent onto the plate through the mixing pump.

[0020] By adopting the above solution, a cleaning device solution including an angle adjustment module and a mixing pump is adopted. This design achieves the synergistic effect of efficient cleaning and environmentally friendly treatment of the plate surface: the angle adjustment modules on both sides of the atomizing cleaning nozzle mechanically adjust the spray angle to ensure that the cleaning liquid covers the entire area of ​​the plate and adapts to different plate contours. The mixing pump is driven by pressure to fully mix the biodegradable agent and water to form an environmentally friendly cleaning liquid, which is transported to the nozzle through a water pipe to achieve uniform atomized spraying; its technical principle is that the angle adjustment module dynamically adjusts the spatial position of the nozzle through a rotating or telescopic mechanism to optimize the cleaning path, and the mixing pump uses the principles of fluid dynamics to achieve precise multi-media ratio and pressurized delivery. Combined with the microporous structure of the atomizing cleaning nozzle, it decomposes the liquid into fine droplets. While improving cleaning efficiency and coverage, the biodegradable agent is used to reduce pollutant residues, thereby taking into account both cleaning effect and environmental protection requirements, reducing water resource waste and enhancing process sustainability.

[0021] Preferably, a guide roller group is provided on one side of the base frame, and the guide roller group includes a guide roller, a correction robot arm and a correction sensor. A correction robot arm is provided on one side of the guide roller, and the guide roller is connected to the roll-bearing shaft through the correction robot arm. A correction sensor is provided on one side of the correction robot arm.

[0022] By adopting the above solution, a guide roller group solution including guide rollers, correction robotic arms and correction sensors is adopted. This design realizes dynamic correction and high-precision guide control in the coil conveying process: the correction sensor monitors the coil position deviation in real time and generates a feedback signal, driving the correction robotic arm to adjust the spatial posture of the guide roller. The guide roller forms a linkage correction mechanism with the coil carrying shaft through the robotic arm to ensure that the coil moves stably along the preset path; its technical principle is that the correction sensor captures the edge or center offset of the coil through non-contact detection technology, triggers the servo drive unit of the correction robotic arm after signal processing, applies lateral or angular compensation to the guide roller through the extension or rotation action of the robotic arm, and adaptively adjusts the coil tension distribution in combination with the rolling friction characteristics of the guide roller, thereby eliminating deviation while reducing material surface wear, improving conveying centering accuracy and equipment coordination, and ultimately ensuring the efficient and stable operation of the continuous production line and reducing the scrap rate.

[0023] Preferably, it also includes a lifting roller, which includes a lifting drive motor, a linear guide rail is provided on one side of the lifting drive motor, a slider is provided on one side of the linear guide rail, a power roller is provided on one side of the slider, and a free roller is provided on one side of the power roller, and the power roller and the free roller are displaced up and down along the linear guide rail through the slider.

[0024] By adopting the above solution, a lifting roller scheme including a lifting drive motor, linear guide rails, sliders, powered rollers and free rollers is adopted. This design achieves dual optimization of adaptive material height adjustment and conveying stability: the lifting drive motor drives the powered roller and the free roller to lift and lower vertically synchronously through the rigid guide structure of the linear guide rails and the sliders. The powered roller provides active conveying power, and the free roller assists in supporting the material and reducing friction resistance. The technical principle is to utilize the high-precision guiding characteristics of the linear guide rails to ensure the straightness and position accuracy of the slider lifting trajectory. The lifting drive motor realizes the smooth displacement of the roller assembly through closed-loop servo control. The coordinated action of the powered roller and the free roller can not only adapt to the material stacking height requirements of different processes, but also maintain the dynamic balance of tension during the conveying process, thereby effectively avoiding material jamming or deformation while improving the flexibility of the production line, reducing the impact load of the equipment and extending the service life of key components.

[0026] By adopting the above scheme, a transmission mechanism scheme including an AC variable frequency motor, a reduction gear unit, an anti-slip belt, a steel roller group, a positioning unit and a guide rib is adopted. The design realizes the coordinated control of high-speed and stable material transportation and precise positioning: the AC variable frequency motor adjusts the output torque and speed through the reduction gear unit, drives the steel roller group to drive the anti-slip belt to operate at a uniform speed, the positioning unit monitors the material position in real time and adjusts the belt operation status through feedback, and the guide rib constrains the lateral deviation of the material; its technical principle is to utilize the wide-band speed regulation characteristics of the AC variable frequency motor to adapt to different conveying speed requirements, the high-rigidity support structure of the steel roller group combined with the surface texture of the anti-slip belt enhances the friction coefficient, the positioning unit realizes dynamic material correction through photoelectric or mechanical sensing technology, and the guide rib forms a physical guide channel through lateral limitation, thereby improving the conveying efficiency and positioning accuracy while reducing the risk of material slippage and stacking, and ensuring the reliability of continuous operation of the production line and process consistency.

[0050] Feeding mechanism 4: The feeding mechanism 4 includes a photoelectric sensor array 401, a drive system 402, a feed roller assembly 403, an anti-error correction structure 404, and a guide support structure 405. The photoelectric sensor array 401 is connected to the feed roller assembly 403. The drive system 402 is provided on one side of the feed roller assembly 403. The anti-error correction structure 404 is provided on the outer wall of the feed roller assembly 403. The guide support structure 405 is provided inside the feed roller assembly 403.

[0051] Lifting material receiving platform 5: The lifting material receiving platform 5 includes an electric lifting module 501, an intelligent stacking control system 502 and a conveying mechanism 503. The electric lifting module 501 is provided on one side of the conveying mechanism 503, and the intelligent stacking control system 502 is provided on one side of the electric lifting module 501.

[0052] Specifically, the unwinding mechanism 1 drives the axial displacement of the coil-bearing shaft 102 to adapt to different coil diameters through the hydraulic expansion and contraction mechanism 103. The hydraulic principle controls the extension and contraction of the shaft core through the oil pressure difference. The cleaning device 2 has a pollution detection unit 202 in the closed cleaning chamber 201 to identify impurities on the surface of the coil and trigger the atomizing cleaning nozzle 203 to spray cleaning liquid. Its closed design prevents droplets from splashing. The leveling mechanism 3 adopts a double-layer staggered layout of rigid rollers 3011 and elastic rollers 3012. The piezoelectric sensor 302 monitors the pressure between the rollers in real time and provides feedback to adjust the roller gap. The synergistic effect of rigid roller 3011 applying pressure and elastic roller 3012 providing cushioning eliminates material stress and deformation. The feeding mechanism 4 detects material position deviations using a photoelectric sensor array 401.

[0054] Specifically, the loading trolley 601 carries the coil and moves it to the unwinding mechanism 1 station, and the loading cover 602 is fixed on the top of the loading trolley 601 and forms a rotational connection with the unwinding mechanism 1 through a hinge or a rotating shaft. The principle is that the loading cover 602 rotates synchronously with the coil unfolding angle during the unwinding process, and the degree of freedom of the rotating pair is used to compensate for the position deviation between the coil and the unwinding mechanism 1. At the same time, the loading trolley 601 and the loading cover 602 form a closed loading unit to ensure that the coil is not offset or slipped during transportation; in terms of connection relationship, one end of the loading cover 602 is hinged to the base frame 101 of the unwinding mechanism 1, and the other end is temporarily fixed to the loading trolley 601 by a mechanical lock or a magnetic device. When the coil is loaded, the loading cover 602 is unlocked after moving to the unwinding station with the loading trolley 601 and rotates around the rotating shaft to unfold, realizing seamless connection of the coil from the transportation state to the unwinding state, thereby reducing manual intervention and improving the automation level and positioning accuracy of the loading and unloading process.

[0056] Specifically, after the material is received by the receiving plate 701, the horizontal inclination angle is adjusted by the rotating shaft 702 to adapt to different feeding directions. The telescopic rod 703 under the receiving plate 701 drives the pinching platform 704 to rise and fall vertically to match the change in material thickness. The pinching roller 705 inside the pinching platform 704 clamps the material through rolling friction and transports it along a preset path; its principle is that the rotating shaft 702 adjusts the receiving angle of the receiving plate 701 through rotational motion to ensure that the material slides into the pinching station in the center, the telescopic rod 703 compensates for the height difference of the material through linear displacement to maintain a constant pressure between the pinching platform 704 and the material surface, the pinching roller 705 adopts a double-roller pressure structure combined with servo drive technology to provide controllable clamping force and conveying power in rolling contact, and each component forms a spatial posture adaptive adjustment mechanism through mechanical linkage, thereby eliminating material deviation and surface scratches while improving pinching accuracy and process compatibility, and realizing the full process automation connection from material receiving, positioning to stable transmission.

[0057] Reference Figure 1 、 Figure 2 and Figure 6 , and also includes an NC sizing system 8, which includes a laser rangefinder 801, a drive motor 802, a numerical control system 803, a flying shear 804 and a data communication module 805.

After parsing the instructions, the CNC system 803 controls the drive motor 802 to adjust the shearing speed and position of the flying shear 804. The flying shear 804 completes fixed-length cutting under the triggering of the synchronization signal. The principle is that the laser rangefinder 801 uses non-contact measurement technology to accurately obtain the material displacement and generate a feedback signal. The drive motor 802 forms a closed-loop linkage with the CNC system 803 through the servo control algorithm. The flying shear 804 uses a high-speed response mechanism to maintain the synchronous movement of the cutting edge and the material during dynamic shearing.

The atomizing cleaning nozzle 203 is sprayed with water containing biodegradable agent on the plate through the mixing pump 205.

[0060] Specifically, angle adjustment modules 204 are installed on both sides of the atomizing cleaning nozzle 203 to adjust the spray angle. The angle adjustment module 204 is connected to the mixing pump 205 through a water pipe. The mixing pump 205 mixes the biodegradable agent and water in proportion and then delivers it to the nozzle to form an atomized cleaning liquid. The principle is that the angle adjustment module 204 drives the nozzle to rotate around the axis through gear transmission or an electric push rod to achieve adaptive adjustment of the cleaning coverage range. The mixing pump 205 uses the centrifugal force of the impeller and the pressure control valve to achieve uniform mixing and pressurized delivery of multiple media. The atomizing cleaning nozzle 203 decomposes the mixed liquid into high-speed droplets through the microporous structure. Combined with the closed environment of the closed cleaning chamber 201, the cleaning liquid fully contacts the surface of the plate and dissolves pollutants. The biodegradable agent decomposes the oil through chemical reactions. Finally, under the synergistic effect of precise control of the spray angle and the ratio of the mixed liquid, the cleaning efficiency and environmental protection are improved, while avoiding liquid waste and secondary pollution.

A correction sensor 903 is provided on one side of the correction robot arm 902.

[0062] Specifically, by installing a guide roller 901 on one side of the base frame 101, the guide roller 901 is mechanically connected to the coil-bearing shaft 102 through a correction robot arm 902 to form a linkage correction structure, and the correction sensor 903 arranged on the side of the correction robot arm 902 monitors the edge position of the coil in real time; its principle is that the correction sensor 903 detects the lateral offset of the coil through photoelectric or ultrasonic waves and generates a feedback signal, and the correction robot arm 902 drives the guide roller 901 to perform lateral displacement or angular deflection according to the signal, and adjusts the material travel trajectory by changing the tangential direction of the contact point between the roller body and the coil, and at the same time, the coil-bearing shaft 102 fine-tunes the unwinding posture synchronously with the correction action, forming a "detection-feedback-execution" closed-loop control system, thereby continuously correcting the coil deviation during the dynamic unwinding process, ensuring that the material is stably transported along the preset center line, reducing the risk of edge wear and improving the alignment and coordination between the unwinding mechanism and the subsequent workstations.

[0063] Reference Figure 1 、 Figure 2 and Figure 9, also includes a lifting roller 10, the lifting roller 10 includes a lifting drive motor 1001, a linear guide rail 1002 is provided on one side of the lifting drive motor 1001, a slider 1003 is provided on one side of the linear guide rail 1002, a power roller 1004 is provided on one side of the slider 1003, and a free roller 1005 is provided on one side of the power roller 1004. The power roller 1004 and the free roller 1005 are moved up and down along the linear guide rail 1002 through the slider 1003.

[0064] Specifically, the linear guide 1002 is driven by the lifting drive motor 1001 to drive the slider 1003 to move vertically. The slider 1003 is rigidly connected to the power roller 1004 and the free roller 1005 to achieve synchronous lifting. The power roller 1004 drives the material conveying through the servo motor, and the free roller 1005 provides unpowered auxiliary support. The principle is that the lifting drive motor 1001 converts the rotational motion into linear displacement through a screw or gear transmission, and the high-rigidity guide structure of the linear guide 1002 ensures the vertical accuracy of the lifting trajectory of the slider 1003. The combination of the power roller 1004 and the free roller 1005 can not only actively push the material but also passively adapt to the gravity distribution of materials of different thicknesses. The roller height is adjusted by lifting and lowering to match the material stacking or connection requirements of each process of the production line, thereby maintaining the conveying tension balance in dynamic adjustment to avoid material accumulation and jamming. At the same time, highly adaptive control is achieved through mechanical linkage to improve the flexibility and operation stability of the production line.

[0065] Reference Figure 1 、 Figure 2 and Figure 8 The conveying mechanism 503 includes an AC variable frequency motor 11, a reduction gear unit 12, an anti-slip belt 13, a steel roller group 14, a positioning unit 15 and a guide rib 16. The AC variable frequency motor 11 is provided with a reduction gear unit 12 on one side, and a steel roller group 14 is provided on one side of the reduction gear unit 12. The outer wall of the steel roller group 14 is provided with an anti-slip belt 13, and a positioning unit 15 is provided on one side of the anti-slip belt 13. Guide ribs 16 are provided at both ends of the anti-slip belt 13.

[0066] Specifically, the AC variable frequency motor 11 drives the reducer group 12 to adjust the output speed and torque, and the reducer group 12 drives the steel roller group 14 to rotate to support and drive the anti-slip belt 13 wrapped on the outer wall to run at a uniform speed. The positioning unit 15 installed on one side of the anti-slip belt 13 uses photoelectric or mechanical sensing technology to monitor the material position in real time, and the guide ribs 16 on both sides of the belt form a physical limit channel; its principle is that the AC variable frequency motor 11 can achieve wide range and precise control of the conveying speed through frequency adjustment, and the high rigidity structure of the steel roller group 14 combined with the concave and convex texture on the surface of the anti-slip belt 13 enhances the friction and adhesion with the material. The positioning unit 15 feeds back the detected material deviation signal to the control system to dynamically correct the belt operation status, and the guide rib 16 guides the material along the center line through lateral constraints. The various components work together to realize the anti-slip, centering and positioning functions during high-speed material transportation, thereby ensuring the synchronization of the production line beat and reducing the risk of material stacking or deviation.

[0067] The implementation principle of the embodiment of the present application is as follows: the unwinding mechanism 1 uses the hydraulic expansion and contraction mechanism 103 to dynamically adjust the axis spacing of the coil bearing shaft 102 to adapt to different coil diameters, and the correction sensor 903 of the guide roller group 9 monitors the coil position in real time and adjusts the guide roller 901 posture through the correction robot arm 902 to ensure the unwinding centering accuracy; the cleaning device 2 triggers the mixing pump 205 and the angle adjustment module 204 through the pollution detection unit 202 to work together, and the biodegradable cleaning liquid is accurately covered on the surface of the plate through the atomization cleaning nozzle 203, and the closed environment is combined with the spray angle adjustment to achieve efficient cleaning; the leveling mechanism 3 adopts a double-layer roller group of rigid roller 3011 and elastic roller 3012 to cooperate with the piezoelectric sensor 302 to feedback pressure data, and dynamically adjust the roller gap to eliminate material stress and deformation; the feeding mechanism 4 detects material deviation through the photoelectric sensor array 401, and the drive system 402 links the anti-error correction structure 404 and the guide support structure 405 to achieve dynamic correction, and the clamping mechanism 7 is through The rotating shaft 702 and telescopic rod 703 adjust the material receiving angle and the height of the pinching table 704, and the rolling friction of the pinching roller 705 ensures stable feeding; the NC sizing system 8 uses the laser rangefinder 801 and the data communication module 805 to establish a real-time feedback chain for material length. After analyzing the data, the numerical control system 803 accurately controls the drive motor 802 and the flying shear 804 to complete fixed-length shearing; the lifting and receiving table 5 adjusts the height of the conveying mechanism 503 to match the material size through the electric lifting module 501 and the intelligent stacking control system 502, and cooperates with the lifting roller 10 of the power roller 1004 and the free roller 1005 to maintain the balance of conveying tension; the entire line relies on the variable speed transmission system constructed by the AC variable frequency motor 11, the reduction unit 12 and the anti-slip belt 13, combined with the positioning unit 15 and the guide rib 16 to ensure precise positioning of the material. Finally, through the mechanical linkage and signal interaction between multiple mechanisms, a "perception-decision-execution" closed loop is formed to achieve continuous production with high precision, high efficiency and high stability.
