Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to a high-speed intelligent power cable laying device. Background Technology

[0002] In wire and cable production, the wire feeding equipment is a key piece of equipment, and its performance directly affects production efficiency and cable quality. Traditional wire feeding equipment generally suffers from the following problems: large fluctuations in wire feeding tension, which can easily lead to cable stretching and deformation or loosening and knotting; unstable wire feeding speed, which is difficult to match with subsequent high-speed production equipment; reliance on manual intervention for loading, unloading and tension adjustment of wire reels, which is inefficient and poses safety risks; and poor equipment versatility, making it difficult to quickly adapt to wire reels of different specifications.

[0003] Currently, traditional or power-driven wire feeding equipment commonly used in the industry faces numerous bottlenecks in practical applications: 1. Low tension control accuracy and large fluctuations: Most equipment uses mechanical friction or simple lever potentiometer feedback control, resulting in slow dynamic response and difficulty in achieving high-precision constant tension control, easily leading to overstretching or loosening and knotting of the cable; 2. Unstable wire feeding speed: Especially with large diameter and high-speed wire feeding, the reel radius changes drastically. Without speed compensation, this will cause significant fluctuations in wire feeding speed, making it unsuitable for downstream high-speed production equipment; 3. Insufficient automation and intelligence: Reel loading, unloading, centering, and clamping rely heavily on manual labor, resulting in low efficiency and safety hazards; the equipment lacks intelligent monitoring and maintenance prompts for its own status (such as lubrication and air pressure); 4. Poor equipment versatility and reliability: Insufficient mechanical structure rigidity makes it prone to deformation and vibration during long-term high-speed operation; difficulty in quickly adapting to reels of different specifications (diameter, width); inconvenient lubrication and maintenance of core transmission components, leading to a high failure rate.

[0004] For example, in the high-speed rope-driven wire laying device disclosed in CN106006188A, a high-speed cable-driven laying device is described, which mainly solves the problem of uncertainty in the position of the wire rope on the reel. It improves the load positioning accuracy by precisely controlling the wiring position. However, this solution focuses on the accuracy of mechanical transmission and does not involve intelligent closed-loop control of tension during the laying process or dynamic compensation of the reel's allowance.

[0005] For example, in the article "A Brief Analysis of Constant Tension Active Wire Release Control System Based on Sifang Electric V560 Vector Inverter", a scheme is introduced to indirectly maintain tension stability by using the PID function of the inverter and the feedback of the swing arm position. Although this method achieves constant tension control to a certain extent, its control accuracy depends on the structure and response of the mechanical swing arm, and it does not introduce feedforward control for changes in the wire reel radius. When dealing with high-speed and large-diameter changes, its dynamic adjustment capability and accuracy still have room for improvement.

[0006] For example, the dual-drive horizontal dual-purpose cable laying device with publication number CN202111370765.0 solves problems such as adapting to cable reels of different sizes, providing stable support when the reel is defective, and manual cable laying during power outages through innovative mechanical structure design. However, its core innovation lies in the adaptability and reliability of the mechanical structure, and intelligent control of the drive and precise tension adjustment are not its focus.

[0007] In summary, existing technologies either suffer from limitations in control strategies (feedback only or feedforward only) or lack in automation and versatility. In particular, they lack a collaborative control strategy and equipment system that deeply couples real-time tension feedback closed-loop control with real-time coil radius change feedforward control. This makes it difficult to achieve high-precision constant tension and constant wire speed pay-off simultaneously under high-speed, large-diameter change conditions. Furthermore, existing equipment is also inadequate in terms of rapid intelligent clamping, overall rigidity and stability, and system maintainability. Therefore, there is an urgent need for a high-speed intelligent power pay-off equipment that integrates intelligent dual closed-loop control (tension feedback + margin feedforward), high-precision electro-proportional valve clamping, integrated rigid frame, and automatic lubrication system to systematically solve the above problems. Summary of the Invention

[0008] This invention provides a high-speed intelligent power wire feeding device that solves the problems mentioned in the background technology above. It can achieve high-precision and stable control of wire feeding tension, adaptive adjustment of wire feeding speed, and has a high degree of automation, strong safety protection and wide compatibility with wire reels.

[0009] The present invention provides the following solution to the above-mentioned technical problems: A high-speed intelligent power cable feeding device includes a frame, a protective cover, a tension detection device, a cable reel balance detection device, a power unit, a clamping device, a lifting device, and a control module. The frame is an integral rigid structure that forms the installation foundation of the device. The protective cover is installed on the frame to form a safe protection space. The tension detection device is located inside the frame and is used to detect the tension of the cable in real time and output a first signal. The cable reel balance detection device is located on the frame and is used to detect the winding radius or balance of the cable reel in real time and output a second signal. The power unit is used to drive the cable reel to rotate and feed the cable. The clamping device is used to clamp the cable reel from the side of the inner hole of the cable reel. The lifting device is used to lift the cable reel to the working position.

[0010] The control module is electrically connected to the tension detection device, the spool balance detection device, the power device, and the clamping device. The control module receives the first signal and the second signal, and dynamically adjusts the speed of the power device based on the first signal to stabilize the wire feeding tension. At the same time, it feeds forward and adjusts the speed of the power device based on the second signal to compensate for changes in the spool radius.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the frame is formed by one-piece casting or integral welding process and undergoes aging treatment. The frame includes a frame body, which is equipped with a frame cover plate, cable trays, cable tray covers, vibration damping feet, cable gauge mounting slots, and cable covers. The integrated frame provides support and installation foundation for the entire power cable laying equipment, ensuring its structural stability and preventing component displacement due to vibration. The use of an integrated rigid structure and aging treatment greatly improves the overall strength, rigidity, and dimensional stability of the frame, effectively resisting vibration and impact generated during high-speed operation, and preventing the displacement or damage of precision components due to foundation deformation or vibration. This ensures the long-term accuracy and reliability of the equipment. The integrated design (such as cable trays and cable gauge mounting slots) makes the internal layout of the equipment more organized, cable management safer, and external accessory installation more convenient, improving the overall integrity and ease of use of the equipment.

[0013] Furthermore, the protective cover and the frame are designed as separate units. The protective cover includes a main housing, which is equipped with an operation panel, inlet / outlet doors, an electrical box door, an air box door, embedded LED work lights, a safety lock, a junction box, an exhaust fan, and a concealed door lock. The inner wall of the main housing is lined with sound-absorbing cotton and has ventilation holes with dust filters. The operation panel is used for human-machine interaction, and the inlet / outlet doors have observation windows for visualizing the internal status of the equipment. The protective cover is used to isolate the high-speed rotating power components inside, preventing personnel injury accidents, and also blocking external debris from entering the equipment. In addition, it... It provides sound insulation and noise reduction, facilitates real-time monitoring of equipment operation and internal wiring status, and enables timely operation and maintenance. The modular design facilitates independent manufacturing, transportation, and maintenance. The multi-functional integration (operation panel, various maintenance doors, and work lights) greatly enhances the equipment's user-friendliness and maintenance convenience. The combination of internal sound-absorbing cotton and dustproof heat dissipation holes effectively reduces equipment operating noise, improves the working environment, and ensures heat dissipation efficiency and internal cleanliness. The observation window and safety lock design enable real-time visual monitoring of the equipment's operating status while ensuring safety, balancing safety and operational transparency.

[0014] Furthermore, the tension detection device includes a central column, which is equipped with a swing arm, a sensor bracket, a potentiometer, a sensor switch, an encoder, and a pressure gauge. The swing arm is equipped with a wire guide wheel axle, and a wire guide wheel is installed through the wire guide wheel axle. The sensor bracket is equipped with a tension cylinder, a tension sensor, and an amplifier.

[0015] The potentiometer is linked to the pendulum to convert the mechanical position change of the pendulum into a voltage signal. The guide wheel supports and guides the cable and drives the pendulum to swing. The amplifier amplifies the signal from the tension sensor, and the encoder detects the rotation angle of the pendulum. The mechanical structure of the pendulum and guide wheel provides a sensitive response, directly sensing minute changes in line tension. Integrating the potentiometer, tension sensor, and encoder, it can simultaneously provide two high-precision feedback signals: tension magnitude (analog / digital) and pendulum angle position (digital). This provides a multi-dimensional data foundation for the control module to achieve more complex and precise closed-loop and feedforward control, improving the accuracy and dynamic response speed of tension control. The structure is compact and the detection is direct.

[0016] Furthermore, the coil balance detection device is a laser rangefinder, which is installed on the tension detection device. Laser rangefinder has the advantages of high measurement accuracy, fast response speed, and non-contact with the object being measured (coil), thus avoiding the problems of wear, slippage, or interference with the wire feeding process that may be caused by contact measurement.

[0017] Furthermore, the power unit includes a drive shaft, friction disc, telescopic shaft, bearing, reducer, brake disc, synchronous pulley, belt, servo motor, cylinder, and proximity switch. The servo motor is equipped with a motor eccentric seat, the cylinder is equipped with a connecting rod, the belt is tensioned by an eccentric adjustment method, and the power unit adopts an air-cut brake system that automatically triggers the brake when the air pressure is insufficient.

[0018] The friction disc is mounted on the drive shaft to drive the spool to rotate. The drive shaft is connected to the servo motor via a brake disc, belt, and synchronous pulley. The telescopic shaft is used to adapt to spools of different specifications.

[0019] The servo motor, with its torque adjusted by a gearbox, drives the drive shaft and friction disc via a synchronous belt drive assembly. This eliminates the need for a traditional pin mechanism, providing stable power for high-speed wire unloading. The servo motor, combined with the synchronous belt drive, offers precise speed control and smooth power transmission. The eccentric tensioning method simplifies belt maintenance and ensures stable tension. The friction disc directly drives the side of the wire reel, eliminating the need for a traditional through-shaft pin mechanism and simplifying the reel loading process. This makes it particularly suitable for high-speed wire unloading. The air-stop brake system, as a safety redundancy, automatically locks the shaft in case of air supply failure, preventing the wire reel from running away uncontrollably and ensuring high safety. The telescopic shaft design enhances the equipment's adaptability to wire reels of different widths.

[0020] Furthermore, the clamping device includes a top shaft, a cylinder, a cylinder fixing plate, a cylinder mounting plate, a movable cantilever seat, a slider, a slide rail, and a sensor switch. The cylinder is mounted on the cylinder fixing plate via the cylinder mounting plate. The slider is located at the drive end of the cylinder. The movable cantilever seat is mounted on the slider. The top shaft is located on the movable cantilever seat. The top shaft is used to clamp the spool from the inner hole of the spool. The movement of the cylinder drives the top shaft to clamp the spool from the inner hole of the spool, eliminating the need for a traditional spool shaft to pass through. The slider is slidably connected to the slide rail. The sensor switch is located on the slider. The control module is electrically connected to the slide rail. The proportional valve linearly adjusts the pressure output to the cylinder, and the clamping action is determined by pressure feedback and a position sensor switch. The lateral clamping method completely eliminates the step of inserting the long shaft, making the loading and unloading of the reel extremely fast and labor-saving. The slide rail slider guide ensures the straightness and stability of the top shaft movement. The clamping force is linearly and steplessly adjusted by the electric proportional valve, which can accurately adapt to reels of different materials and structures to avoid damage. The combination of pressure feedback and position sensor switch provides double confirmation, which is highly intelligent and can reliably ensure that each clamping action is accurate, in place, and with appropriate force.

[0021] Furthermore, the lifting device includes a coil lifting platform, a lifting screw, a drive motor, proximity switches, a lifting adjustment rod, and a lifting adjustment plate. The lifting adjustment rod is a telescopic rod, and its telescopic end is connected to the coil lifting platform via the lifting adjustment plate. The drive motor is equipped with a lifting screw, which drives the coil lifting platform to finely adjust its lifting height. Proximity switches at different heights are used to adapt to and position coils of different specifications. The screw-driven lifting mechanism ensures precise positioning, good self-locking, and stable maintenance of the lifting height. Combined with proximity switches at different heights, coils of different diameters can be quickly and automatically positioned to a preset reference working height, achieving automation and standardization of height adjustment. This reduces the time spent on manual measurement and adjustment, improves coil changing efficiency and positioning accuracy, and ensures the consistency of the centerline of coils of different specifications during operation.

[0022] Furthermore, the device also includes an air circuit system, an automatic lubrication system, and a rotating grounding device;

[0023] The pneumatic system includes an electro-proportional valve, a solenoid valve, an air tank, a safety valve, an air filter, a pressure reducing valve, and an oil mist lubricator. The safety valve is used to prevent system overpressure, the air filter is used to filter compressed air, the pressure reducing valve is used to regulate the pneumatic pressure, and the oil mist lubricator is used to lubricate pneumatic components.

[0024] The automatic lubrication system includes an electric grease pump, a progressive distributor, a low oil pressure alarm device, and a low oil pressure alarm device, which are used to issue an alarm when the oil pressure is too low to ensure that the lubrication system works normally.

[0025] The rotating grounding device is used to discharge static electricity or stray current generated during equipment operation. The highly integrated and standardized pneumatic system (including filtration, voltage stabilization, lubrication, and safety protection) ensures the reliability of pneumatic components (such as cylinders and brakes). The automatic lubrication system realizes timed, quantitative, and fixed-point lubrication, which significantly reduces the wear of key transmission components, extends the service life of the equipment, and prevents failures caused by poor lubrication through the alarm device. The rotating grounding device effectively conducts static electricity that may be generated by high-speed friction, protects the insulation performance of sensitive cables (such as communication cables), and improves the safety of the equipment in flammable and explosive environments. These auxiliary systems together ensure the long-term, stable, and safe unattended or continuous operation capability of the equipment.

[0026] A method for intelligent control of a high-speed intelligent power wire laying device includes the following steps:

[0027] S1, the control module receives a first signal of real-time detection value of cable tension and a second signal of real-time detection value of cable reel balance;

[0028] S2, compare the real-time detected value of the cable tension with the preset target tension value, calculate the first speed correction amount through the PID control algorithm, and adjust the speed of the power device in a closed loop;

[0029] S3, calculate the current winding radius of the spool based on the real-time detection value of the spool's remaining amount, and calculate the required power unit rotation speed based on the preset target linear speed and the current winding radius, as the second speed correction amount;

[0030] S4, the first speed correction amount and the second speed correction amount are combined to generate the final speed command and send it to the power unit.

[0031] The beneficial effects of this invention are as follows: This invention provides a high-speed intelligent power wire laying device, which has the following advantages:

[0032] 1. It achieves high-precision and high-dynamic intelligent tension and speed control, and adopts dual closed-loop fusion control. It combines PID closed-loop control based on real-time tension feedback (to eliminate random interference) and feedforward control based on real-time detection of the coil radius (to actively compensate for changes in coil diameter). In principle, it achieves synchronous high-precision stability of pay-off tension and linear speed, which significantly improves pay-off quality and provides stable input for downstream high-speed production.

[0033] 2. Through the automatic height positioning of the lifting device, the force control and position confirmation of the electric proportional valve of the clamping device, and the adjustment of the telescopic shaft of the power unit, the equipment can quickly and automatically complete the clamping and centering of different specifications of reels, greatly reducing manual intervention, improving reel changing efficiency and safety. The control system can intelligently determine the clamping completion and lubrication status, and automatically brake when the air source fails, improving the reliability and safety of operation.

[0034] 3. The overall rigidity, stability, and durability of the equipment are enhanced. The one-piece molded and aged frame provides a robust and stable mounting platform for all precision components, effectively suppressing high-speed vibration and ensuring long-term operational accuracy. The servo motor combined with synchronous belt drive provides precise and stable power. The friction disc side drive simplifies the structure and is suitable for high-speed operation. The use of standardized air circuits, automatic lubrication systems, and rotating grounding devices ensures reliable operation of pneumatic components, reduces mechanical wear, extends equipment life, and eliminates static electricity hazards.

[0035] 4. Improved human-machine interaction, safety protection, and maintainability: The split-type protective cover integrates the operation panel, LED lights, observation windows, and various maintenance doors, making equipment operation intuitive, status visible, and maintenance convenient. The protective cover provides physical isolation and sound insulation and noise reduction; multiple measures such as safety locks and air cut-off brakes ensure the safety of personnel and equipment. The rack integrates cable management, the belt adopts eccentric tensioning, and the modular layout of each system makes daily inspection and maintenance more convenient.

[0036] 5. Through the deep integration of high-rigidity frame, multi-sensor detection (sensing), intelligent electro-hydraulic-pneumatic actuation (execution), dual-mode fusion algorithm (control), and comprehensive safety protection (guarantee), a collaborative and high-performance system has been built, which fundamentally improves the comprehensive performance indicators of power wire laying equipment and is suitable for modern wire and cable production scenarios with stringent requirements for efficiency, quality, and safety.

[0037] 5. Through a unique dual-mode fusion control strategy, the feedback closed-loop regulation used to overcome random disturbances is organically combined with the feedforward open-loop regulation used to compensate for predictable changes in roll diameter. The control module is equivalent to an intelligent hub with the ability to 'reflect' (quickly respond to tension fluctuations) and 'anticipate' (adjust the rotation speed in advance to adapt to radius changes), thus breaking through the bottleneck of traditional single control mode in terms of dynamic accuracy and response speed.

[0054] The following is in conjunction with the appendix Figure 1-12 The principles and features of the present invention are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0055] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] like Figure 1-4 As shown, the present invention provides a high-speed intelligent power wire laying device, which is wrapped by a complete protective cover 2 to form an integrated working unit that combines safety, noise reduction and observation. The protective cover 2 and the internal load-bearing structure adopt a separate design, which is convenient for independent manufacturing, transportation and maintenance. The front of the protective cover 2 integrates an operation panel 202, a wire entry and exit door 203 with a transparent observation window 206, an electrical box door 204 and an air box door 205, which facilitates parameter setting, status monitoring and rapid maintenance of electrical and pneumatic systems.

[0058] like Figure 5 As shown, the frame 1 is the core of the entire equipment and the foundation for precision. The frame body 101 is integrally welded from high-quality steel to form a robust frame structure. All major mounting surfaces are precision milled and stress-relieving aging treatment is performed after welding to completely eliminate internal stress and ensure its extremely high overall rigidity and long-term dimensional stability. This integrated rigid structure design can effectively resist the vibration and impact generated during high-speed start-up, shutdown, and operation of the equipment, providing a stable and reliable installation benchmark for high-precision moving parts such as the power unit 5 and clamping device 6, fundamentally avoiding precision degradation caused by foundation deformation. The frame body 101 integrates a wire trough 103 and a wire trough cover 104 for organizing internal power and control cables. The side is provided with a standardized wire gauge mounting groove 106 to facilitate the quick installation and adjustment of subsequent guide devices. Multiple high-performance shock-absorbing feet 105 are installed at the bottom to form a second line of shock absorption, effectively absorbing and isolating vibrations transmitted from the ground and protecting precision components. The frame cover plate 102 is used to enclose non-operating areas and maintain a clean appearance.

[0059] The protective cover 2 is formed by bending metal sheet and is detachably connected to the frame 1. Its inner wall is fully covered with environmentally friendly sound-absorbing cotton 209, which significantly reduces the noise when the equipment is running at high speed. The side of the protective cover has heat dissipation holes with dustproof nets, which ensure heat dissipation efficiency while preventing dust from entering. The design of the observation window 206 and the embedded LED work light 207 allows the operator to clearly observe the internal wiring status without opening the door. The design of safety lock 208 and hidden door lock 2012 improves the overall appearance while ensuring operational safety.

[0060] like Figure 6 and Figure 7 As shown, the tension detection device 3 is the sensory nerve of the control system. Its central column 301 is firmly installed on the frame 1. The swing arm 302 can swing sensitively around the central column 301 through a high-performance bearing. One end of the swing arm 302 is equipped with a low-resistance wire guide wheel 3012 through the wire guide wheel shaft 309. The cable in the wire laying passes over this wheel. Any slight change in the cable tension will be directly converted into the angular displacement of the swing arm 302.

[0061] To obtain tension information in real time and accurately, this embodiment adopts a composite detection scheme:

[0062] Direct tension measurement: The direct measurement unit consists of a tension cylinder 303, a high-precision tension sensor 305, and a signal amplifier 306. The tension is directly transmitted to the tension sensor 305 through the lever action of the swing rod 302. After amplification, an analog or digital signal representing the absolute value of the tension is output (as the core of the first signal).

[0063] Indirect position feedback: The rotating shaft of potentiometer 307 is mechanically linked with the rocker arm 302. The swing angle of the rocker arm 302 is linearly converted into the change in the resistance value of potentiometer 307, which in turn outputs a continuous voltage signal. This signal reflects the relative change trend of tension and responds extremely quickly, providing fast dynamic feedback for the control system.

[0064] Auxiliary monitoring: Encoder 308 provides a higher resolution digital signal of the lever angle; Pressure gauge 3011 is used for local monitoring of the tension cylinder pressure status;

[0065] At the same time, such as Figure 7 As shown, the coil remaining length detection device 4 uses a high-precision laser rangefinder, which is integrated on the tension detection device 3. The laser rangefinder's transmitter continuously emits a laser beam toward the rotating coil winding surface and receives the reflected signal. By calculating the time difference, the precise distance to the cable surface is measured non-contactly and in real time. As the cable is unwound, the coil radius R decreases and the measurement distance L increases. Based on this distance value L and the device's geometric parameters, the control module can calculate the current winding radius R of the coil or the remaining cable length in real time, forming a second signal for feedforward control.

[0066] like Figure 8 As shown, the power unit 5 is the core that provides stable and controllable wire-laying power. The servo motor 509 serves as the drive source, possessing high speed, high torque, and excellent speed regulation performance. Its output is transmitted to the reducer 505 through the synchronous pulley 507 and the high-strength synchronous toothed belt 508. The synchronous belt 508 is tensioned using a unique motor eccentric seat 5012. The belt tension can be conveniently and steplessly adjusted by rotating the eccentric seat. The structure is compact and maintenance-free, eliminating the need for a traditional external tensioning pulley. The reducer 505 converts the high speed of the motor into the speed required to adapt to the starting and running of the large inertia reel. High torque drives the drive shaft 501 and the friction disc 502 mounted at its end to rotate. The friction disc 502 is directly coupled to the side end face of the coil through friction, completely eliminating the traditional through-shaft and pin method, making the coil installation operation extremely simple, especially suitable for high-speed conditions. The design of the telescopic shaft 503 allows the equipment to quickly adapt to coils of different widths. The device also integrates an air-stop braking system (controlled by cylinder 5010 to brake disc 506). When the system detects that the air source pressure is lower than the safety threshold, it is automatically triggered to lock the brake disc, preventing the coil from going out of control and forming a key safety redundancy.

[0067] like Figure 9 As shown, the clamping device 6 is responsible for achieving fast, non-destructive, and intelligent clamping and centering of the coil. Its core consists of two sets of high-rigidity clamping mechanisms arranged symmetrically on the left and right. Each mechanism includes: a drive cylinder 602, a cylinder fixing plate 603, a cylinder mounting plate 604, a movable cantilever seat 605, a precision linear slider 606, a high-rigidity slide rail 607, and a top shaft 601. The cylinder 602 is fixed by the mounting plate, and its piston rod drives the slider 606 to perform high-precision linear motion on the slide rail 607, thereby driving the movable cantilever seat 605 and the top shaft 601 to move forward or backward.

[0068] Its intelligent clamping process is as follows: After the wire reel is positioned by the lifting device 7, the control module, according to the selected wire reel specifications, sends a signal to the electro-proportional valve 801 (see...). Figure 11 The system sends a target clamping pressure command. The electro-proportional valve 801 linearly and precisely adjusts the air pressure output to the cylinders 602 on both sides according to this command. The cylinders drive the top shaft 601 to move smoothly until the conical end of the top shaft 601 is tightly attached to the inner wall of the coil. During this process, the pressure feedback unit inside the electro-proportional valve 801 transmits the actual cylinder pressure back to the control module in real time, compares it with the target pressure, and makes fine adjustments. At the same time, the inductive switch 608 installed on the movement path of the movable cantilever 605 is used to detect the mechanical position of "clamping in place". The control module only determines that the clamping action is reliably completed and enters the next process after receiving the dual confirmation signals of "pressure reached" and "position in place" at the same time. This "force-position" dual closed-loop control ensures that the clamping force is sufficient to prevent high-speed slippage and will not damage the inner edge of the coil.

[0069] like Figure 10 As shown, the lifting device 7 achieves a high degree of automation and standardization in spool loading. The heavy-duty spool lifting platform 701 is used to support the spools on the ground. The drive motor 703 provides the main lifting power through the lifting screw 702. The lifting adjustment rod 705 (which can be an electric push rod or a servo cylinder) is connected to the lifting platform through the lifting adjustment plate 706 and is used to fine-tune the final height to ensure accurate centering of spools of different specifications. On the uprights of the frame 1, proximity switches 704 of different heights are pre-installed for different standard spool diameters (such as 630mm, 500mm, and 400mm). The operator only needs to select the spool specification through the operation panel 202, and the control module can automatically control the operation of the lifting device 7 until the corresponding proximity switch 704 is triggered, thereby automatically and quickly positioning the center line of spools of different diameters to a uniform preset working height, which greatly improves the efficiency and accuracy of spool changing.

[0070] like Figure 11 , Figure 12 As shown, the pneumatic system 8 provides clean, stable, and controllable power for automated execution. Compressed air is purified by air filter 805, stabilized by pressure reducing valve 806, and lubricated by oil mist lubricator 807. Then, it is controlled by solenoid valve 802 to distribute the air pressure under PLC control. The core component, electro-proportional valve 801, adjusts the air pressure to clamping cylinder 602 steplessly and linearly according to control commands. Air tank 803 is used to stabilize system pressure and avoid fluctuations. Safety valve 804 provides overpressure protection.

[0071] The automatic lubrication system 9 (shown schematically in the figure) includes an electric grease pump 901, a plate-type progressive distributor 902, etc. The system can automatically start according to a preset cycle, and distribute the grease quantitatively and sequentially to all key friction pairs such as the main bearing 504 of the power unit 5, the slider 606 of the clamping device 6, and the lead screw and nut pair of the lifting device 7 through the progressive distributor 902, so as to achieve fully automatic lubrication with timed, quantitative, and fixed-point lubrication. The oil shortage alarm device 903 and the low oil pressure alarm device 904 will promptly alarm when the grease is insufficient or the system is blocked, so as to prevent equipment wear or failure due to poor lubrication.

[0072] The rotary grounding device 10 reliably guides the static electricity and stray current generated by friction during the high-speed operation of the equipment to the ground through carbon brushes, protecting the insulation performance of the cable and improving the operational safety in sensitive environments.

[0073] The core process of the control method is executed by the control module (such as a PLC):

[0074] Dual signal synchronous acquisition: Real-time reading of the first signal (tension Fi) from tension sensor 305 / potential 307, and the second signal (distance L, used to calculate the current roll diameter R) from laser rangefinder 4;

[0075] Dual-mode fusion control calculation:

[0076] Feedback closed loop (PID control): The real-time tension Fi is compared with the set target tension F0, and the speed adjustment Δn1 required to eliminate the instantaneous tension deviation is calculated by the PID algorithm;

[0077] Feedforward open loop (coil diameter compensation): Based on the target line speed V and the real-time calculated coil diameter R, the theoretical base speed required to maintain a constant line speed V is calculated according to the formula n_base=V / (2πR). This base speed is compared with the current actual speed to obtain the speed adjustment amount Δn2 used to actively compensate for changes in coil diameter.

[0078] Command synthesis and output: The feedback correction amount Δn1 and the feedforward correction amount Δn2 are merged to generate the final comprehensive speed command, which is sent to the driver of the servo motor 509. This method uses both the feedback correction capability and the feedforward prediction capability to enable the system to respond quickly to random disturbances and to compensate for predictable changes in roll diameter in advance, thereby achieving high-precision constant tension and constant linear speed control at high speed.

[0079] The specific working principle and usage method of this invention are as follows:

[0080] S1. Equipment initialization and cable reel loading: The operator places the cable reel fully loaded with cables (e.g., 630mm, 500mm, or 400mm in diameter) onto the cable reel lifting platform 701, which has been lowered to its lowest position. Through the operation panel 202 (an industrial touch screen can be selected) installed on the outside of the equipment, the operator selects or inputs the standard specifications of the current cable reel. The control module (e.g., an S7-1200 / 1500 series PLC) receives the instruction and retrieves the preset parameters corresponding to the specifications from the internal memory, including the target lifting height and the clamping target pressure.

[0081] S2. Intelligent clamping and automatic centering: This step is crucial to ensure that the subsequent high-speed wire feeding does not slip or vibrate. The control module first starts the lifting device 7, and the drive motor 703 (such as SEW's DRN series geared motor) drives the lifting platform to rise through the lifting screw 702. When the lifting platform drives the wire reel to rise to the height corresponding to the preset specification, the corresponding proximity switch 704 (such as Omron E2E series) fixed on the frame column is triggered. The PLC determines that the height is in place and stops the lifting motor. At this time, the center of the wire reel has been initially aligned with the center of the equipment drive shaft.

[0082] Subsequently, the control module initiates the intelligent clamping process, the core of which is a force-position dual closed-loop system controlled by an electro-proportional valve (801) (such as the FESTOMPPE series):

[0083] Command issuance: The PLC outputs a corresponding analog control signal (such as a 4-20mA current signal) to the electro-proportional valve according to the coil specifications.

[0084] Precision pressure drive: According to the signal, the electric proportional valve linearly and precisely adjusts the air pressure output to the two drive cylinders 602 (such as SMC standard cylinders) in the clamping device 6. The cylinder rod extends and, through the precision guide mechanism formed by the slider 606 and the slide rail 607 (such as linear guide rail), pushes the movable cantilever seat 605 and its front top shaft 601 to move smoothly into the inner hole of the coil.

[0085] Dual-condition judgment completed: During the top axis forward movement:

[0086] Pressure closed loop: The pressure sensor built into the electric proportional valve feeds back the current pressure value of the cylinder to the PLC in real time. The PLC compares this feedback value with the preset "target clamping pressure" in real time and performs PID fine-tuning to ensure that the pressure is accurate and controllable, preventing slippage due to insufficient pressure and avoiding damage to the coil due to excessive pressure.

[0087] Position confirmation: When the conical surface of the top shaft is fully in contact with the inner wall of the coil and reaches the preset clamping position, it will trigger the induction switch 608 (such as an Omron miniature limit switch) installed near the movable cantilever seat.

[0088] The PLC only determines that the clamping action is complete when it receives two signals at the same time: "pressure feedback value has reached the target range" and "inductive switch triggered". It then locks the current output state of the electro-proportional valve. This dual confirmation mechanism ensures the reliability and consistency of clamping.

[0089] S3. Threading and parameter setting: The operator opens the inlet / outlet door 203 on the protective cover, leads the cable end out of the spool, passes it around the wire guide wheel 3012 on the tension detection device 3, and passes it through the equipment outlet. Then, the operator sets the key process parameters for this production on the operation panel: target wire tension (F0) and target wire speed (V0). These parameters will be used as the set values ​​for the control algorithm.

[0090] S4. Start and dual-mode integrated intelligent control for wire feeding. This step is the core of the invention’s intelligence. After pressing the start button, the equipment enters the automatic operation state.

[0091] 1. Real-time data acquisition:

[0092] Tension signal acquisition: The cable tension acts on the cable guide wheel 3012, causing the rocker arm 302 to produce angular displacement. This displacement is detected simultaneously by two sensors: one is a potentiometer 307 (such as a Bourns precision potentiometer), which outputs a continuous voltage signal proportional to the rocker arm angle; the other is a tension sensor 305 (such as an HBM miniature tension / compression sensor), which directly outputs an analog signal corresponding to the tension. The two signals are processed and used as the first signal (real-time tension Fi) input to the PLC.

[0093] Cable reel balance signal acquisition: A laser rangefinder 4 (such as SICKDT35 series) mounted on a sensor bracket continuously measures the distance (Li) between itself and the surface of the rotating cable reel in a non-contact manner. The PLC calculates the current cable reel winding radius (Ri) in real time based on the fixed geometric parameters of the equipment, forming a second signal.

[0094] 2. Dual-mode fusion control algorithm execution:

[0095] The PLC executes the following algorithm within each scan cycle (typically 1-10ms):

[0096] Tension feedback closed-loop control (PID algorithm):

[0097] Calculate the tension deviation: e(t) = F0 - Fi(t);

[0098] The first speed correction is calculated using a digital PID algorithm:

[0099] Δn1(t)=Kp*e(t)+Ki*Σe(t)*T+Kd*[e(t)-e(t-1)] / T

[0100] Where Kp, Ki, and Kd are pre-tuned proportional, integral, and derivative coefficients, T is the control period, and Δn1(t) is used to quickly eliminate random tension fluctuations caused by friction changes, external disturbances, etc.

[0101] Open-loop control with feedforward for roll diameter:

[0102] Based on the principle of constant linear velocity, the theoretical motor speed required to maintain the target linear velocity V0 at the current roll diameter Ri is calculated as follows:

[0103] n_base(t)=V0 / (2*π*Ri(t))

[0104] By comparing this theoretical speed with the final command speed of the previous cycle, the second speed correction amount Δn2(t) is obtained. Its function is to actively and proactively compensate for the inevitable decrease in linear speed caused by the decrease in the coil radius Ri over time.

[0105] Instruction fusion and output:

[0106] The two correction values ​​mentioned above are then combined with the base command from the previous cycle to generate the final speed command:

[0107] N_final(t)=N_final(t-1)+Δn1(t)+α*Δn2(t)

[0108] (where α is the feedforward weighting coefficient, usually set to a value close to 1 to ensure effective compensation for the main disturbance—the change in roll diameter).

[0109] The final command is sent to the driver of the servo motor 509 (such as the Yaskawa Σ-7 series) via a high-speed fieldbus (such as EtherCAT) or analog module. The servo motor precisely executes the speed and drives the friction disc 502 through synchronous belt drive (the belt 508 is continuously tensioned by the motor eccentric seat 5012). Finally, the friction force drives the wire spool to rotate at high speed and smoothly to unload the wire.

[0110] S5. Full-process safety monitoring and automatic maintenance: During the laying process, the auxiliary system works continuously to ensure equipment reliability and safety.

[0111] Safety protection: The pressure sensor in the air circuit continuously monitors the system pressure. If the air pressure is lower than the safety threshold (e.g., 0.4MPa), the air cut-off braking system will immediately activate, and the brake cylinder 5010 will push the brake pads to lock the brake disc 506, thus achieving fault safety protection.

[0112] Automatic lubrication: The controller of the automatic lubrication system 9 (such as the Trico intelligent lubricator) starts the electric grease pump 901 according to the preset cycle. The grease is injected quantitatively and at fixed points into key friction pairs such as bearing 504 and slider 606 through the progressive distributor 902. The oil shortage alarm device 903 and the low oil pressure alarm device 904 will alarm when there is an abnormality.

[0113] Status monitoring and early warning: The operation panel displays operating parameters such as tension, speed, roll diameter, and pressure in real time. Any abnormality (such as tension exceeding the limit, laser ranging failure, lubrication failure) will trigger an audible and visual alarm and be recorded.

[0114] S6. Cable feeding end and automated reel unloading: When the reel is empty or needs to be replaced, operate the "Unload Reel" button, and the equipment will automatically execute the following sequence:

[0115] Release drive: The PLC controls the servo motor to stop and instructs the electro-proportional valve of clamping device 6 to reduce the output pressure to a lower holding value;

[0116] Slight lifting and disengagement: The control lifting device 7 slightly lifts the coil so that its end face disengages from the drive friction disc 502;

[0117] Release clamping: The solenoid valve of the clamping device reverses, the cylinder retracts the top shaft, and the retraction action stops when the top shaft retracts to the point where the "release in place" induction switch is triggered;

[0118] Lowering and unloading: The lifting device drives the lifting platform to descend to the lowest position, and the empty wire reel falls back onto the platform;

[0119] The operator removes the empty tray, resets all components of the equipment, and prepares to begin the next work cycle.
