Description

Technical Field

[0001] The present application relates to the technical field related to conveyors, and in particular to an automatic balancing adjustment method for a deviation-correcting device of a belt conveyor. Background Art

[0002] In modern industrial automation and logistics transmission systems, belt conveyors are the core equipment for material handling. Their operating efficiency and stability are directly related to the effectiveness of the entire production line. However, in actual applications, due to factors such as uneven material distribution, belt aging, installation errors, or dynamic interference during operation, the feed belt of the belt conveyor often deviates. This not only reduces the conveying efficiency, but may also cause equipment failures and even safety accidents. How to effectively monitor and correct the belt deviation problem has become the key to improving the operating stability and safety of the belt conveyor. Existing methods for correcting belt deviation mostly use mechanical or hydraulic adjustment devices. These devices often require manual intervention, making it difficult to accurately monitor and quickly correct belt deviation. In other words, it is difficult to capture the operating status of the belt in real time and accurately determine whether the belt is deviating and the degree and direction of the deviation. In addition, the balance adjustment accuracy and response speed are limited, and the maintenance cost is high, which reduces the correction efficiency and accuracy of the correction device, thereby affecting the operating stability and reliability of the belt conveyor.

[0007] In a possible implementation, the initialization correction point is configured and the following processing is performed: if the transportation mode of the conveyor belt is one-way transportation, the initialization correction point is the end of the belt; if the transportation mode of the conveyor belt is two-way transportation, the initialization correction point is the starting and end of the belt.

[0008] In a possible implementation, the initialization correction point is loaded into the feed belt simulation model for belt operation simulation, and a new point is established based on the simulation results. The following processing is also performed: in the feed belt simulation model, an immediate response correction mechanism is set for the initialization correction point, and multiple belt operation simulations are performed; based on the simulation results, multiple fitting points with a deviation frequency higher than a preset frequency are collected; the distances from the multiple fitting points to the initialization correction point are calculated, and the first fitting point with the farthest distance is extracted; the first fitting point is added to the immediate response correction mechanism, and the simulation results are updated through the feed belt simulation model, and so on, until the updated simulation results show that the deviation frequency of all points is less than the preset frequency.

[0009] In a possible implementation, multiple correction devices located at multiple points are configured with the optimal correction point distribution, and the following processing is also performed: the conductive roller includes a first conductive roller and a second conductive roller, which are symmetrically distributed on both sides of the belt at the multiple points; the electric push rod includes a first push rod and a second push rod, which are symmetrically distributed on both sides of the belt at the multiple points; the conductive roller serves as a power source, is connected to the micro generator to form a power generation module, and provides electrical energy to drive the electric push rod.

[0010] In a possible implementation, the belt deviation is monitored at the multiple points by the conductive rollers in the multiple correction devices to generate offset points and corresponding belt deviation vectors, and the following processing is performed: multiple groups of preset deviation vector samples are established; the conductive rollers are operated with the multiple groups of preset deviation vector samples, and multiple groups of rotation sensor samples are obtained by testing the rotation sensor inside the conductive roller; wherein any group of rotation sensor samples includes rotation speed and rotation direction; a deviation identification model is established with the mapping relationship between the multiple groups of preset deviation vector samples and the multiple groups of rotation sensor samples; the belt deviation is monitored according to the rotation sensor inside the conductive roller through the deviation identification model to generate the offset points and the belt deviation vector.

The terms used herein are for the purpose of describing the embodiments of this application only.

[0020] The embodiment of the present application provides an automatic balancing adjustment method for a belt conveyor deviation correction device, such as Figure 1 As shown, the method includes:

[0021] Step S100: acquiring basic information of a feeder belt of a target belt conveyor, wherein the basic information of the feeder belt includes belt length, belt width, belt structure, and operating load.

[0022] Preferably, the deviation correction device of the target belt conveyor is an intelligent passive power generation automatic straightening device, which uses two conduction rollers installed on both sides of the belt of the feed belt bracket as a power source to dynamically monitor the running condition of the belt in real time. When the belt deviates, it contacts the conduction roller, and its rotation drives the micro high-efficiency generator to generate electricity. The control signal is sent through the inverter rectifier controller to control the high-strength special electric push rod to perform self-guiding work and achieve balance adjustment. Obtain basic information about the feed belt of the target belt conveyor, including belt length, belt width, belt structure and operating load. Specifically, the belt length depends on the position and diameter of each roller in the actual structure of the belt conveyor, as well as the overall design of the conveyor and the material conveying requirements. In order to ensure the uniformity of size, the belt length generally refers to the circumference of the belt median diameter (the center of the belt thickness), rather than the circumference of the belt inner diameter or outer diameter, and the unit is generally millimeters; the belt width is usually between 500 mm and 2000 mm, but there are some special specifications such as 2200 mm or larger width. Different materials have different particle sizes and shapes. It is necessary to select an appropriate belt width according to the characteristics of the material. For example, a narrower belt can be selected for materials with smaller particle sizes, while a wider belt is required for materials with larger particle sizes. The larger the conveying volume, the wider the belt needs to be to ensure uniform distribution of the material and conveying stability.

[0023] Preferably, the belt structure mainly includes the turning point, inclined section, uphill and downhill sections of the belt, etc., which depends on the overall layout of the conveyor and the material transportation requirements. The turning point refers to the turning of the belt conveyor through a specially designed turning device to ensure that the material can remain stable during the turning process. The inclined section needs to consider the gravity of the material, the friction between the belt and the material, and the strength of the belt. Too large an inclination angle may cause the material to slip or the belt to wear more severely. In the uphill and downhill sections, the upper belt section is used to lift the material from a low place to a high place, while the lower belt section is used to transport the material from a high place to a low place; the operating load includes the weight and speed of the transported material. The weight of the material directly affects the carrying capacity of the belt and the operating stability of the conveyor. The belt speed has a great influence on the bandwidth, dead weight, cost and work quality of the belt conveyor. Under the same conveying capacity conditions, you can choose a large bandwidth and low belt speed, or a small bandwidth and high belt speed.

[0024] Step S200 , optimizing the correction nodes of the correction device in combination with the belt length, the belt width, the belt structure and the running load, and generating an optimal correction point distribution.

[0025] Preferably, the correction nodes are optimized in combination with the belt length, belt width, belt structure and operating load to generate the optimal correction point distribution, and then determine at which positions on the belt to install the correction device to most effectively correct the belt deviation problem. Specifically, the correction nodes of the correction device are initialized according to the length, width, structure and load of the belt, and then the effect and stability of the correction device are evaluated through simulation operation of the belt, and new correction points are established according to the evaluation results. The optimal correction point distribution is generated with these multiple correction points. The optimal correction point distribution refers to a solution that optimizes the layout and cost of the correction nodes of the correction device while meeting the requirements for stable operation of the belt, ensuring that the belt can detect and correct deviation problems in a timely and accurate manner throughout its entire length, thereby ensuring stable operation of the belt conveyor and improving production efficiency.

[0026] Further, such as Figure 2 As shown, step S200 also includes step S210, configuring the initialization correction point; step S220, using the belt length, the belt width, the belt structure and the operating load as structural modeling data, and collecting historical belt operation records to establish a feed belt simulation model; step S230, loading the initialization correction point into the feed belt simulation model to perform belt operation simulation, and establishing new points based on the simulation results; step S240, generating the optimal correction point distribution using the new points and the initialization correction point.

[0027] Preferably, the initialization correction point refers to the preset correction device installation position on the belt, which is determined based on the structural characteristics of the belt conveyor, material transportation requirements and common deviation rules before any simulation and optimization is performed, such as the belt head, tail, tensioning roller, and the protruding points, concave arc sections and other positions of the belt frame that are prone to deviation. Initialization correction points may need to be set; then, the belt length, belt width, belt structure and operating load are used as structural modeling data, and historical belt operation records are collected, including the frequency, degree, position and other information of the belt deviation, to construct a simulation model that can simulate the actual operating state of the belt, so as to more accurately evaluate the effect of the correction device and optimize the point distribution; then the initialization correction points are loaded into the feed belt simulation model to simulate the belt operation. Simulation, through simulation, observe the status of the belt under different operating conditions, including whether it is deviating, the degree and direction of the deviation, etc., evaluate the effect of the initial correction point according to the simulation results, and add new points to the simulation model based on the hot spots or potential risk points of the belt deviation in the simulation results, that is, new points. By continuously adjusting and optimizing the point distribution, the probability of belt deviation is gradually reduced, and the efficiency and accuracy of the correction device are improved. After multiple simulations and optimizations, the relatively optimal correction point distribution is obtained. Not only the structural characteristics of the belt conveyor and the material transportation requirements are taken into account, but also the historical records and potential risk points of the belt operation are fully considered, ensuring that the correction device can play the greatest role on the belt, reducing the impact of belt deviation on production efficiency and safety, thereby improving production efficiency and safety.

[0028] Furthermore, step S210 also includes step S211, if the transport mode of the conveyor belt is one-way transport, the initialization correction point is the end of the belt; step S212, if the transport mode of the conveyor belt is two-way transport, the initialization correction point is the starting and end of the belt.

[0029] Preferably, when the transport mode of the conveyor belt is one-way transport, the belt usually carries and transports materials in only one direction. The end of the belt (i.e., the material unloading point or the end of transport) is the position where the belt deviation problem is more prominent. The initialization correction point is set at the end of the belt. Once the belt deviates at the end, the correction device can respond and correct it quickly to ensure that the material can be accurately unloaded and avoid problems such as material scattering or belt damage. When the transport mode of the conveyor belt is two-way transport, the belt needs to carry and transport materials in two directions. The belt may deviate at the starting end (i.e., the material loading point or the starting point of transport) and the end end (i.e., the other material unloading point or the end of transport). The initialization correction point is set at the starting end and the end end of the belt. No matter which direction the belt runs, once the deviation problem occurs, the corresponding correction device can respond and correct it in time to ensure that the impact of the belt deviation on production efficiency and safety is minimized to the greatest extent, and the efficiency and accuracy of the correction device are improved.

[0030] Furthermore, step S230 also includes step S231, setting an immediate response correction mechanism for the initialization correction point in the conveyor belt simulation model, and then performing multiple belt operation simulations; step S232, collecting multiple fitting points whose deviation frequency is higher than the preset frequency according to the simulation results; step S233, calculating the distances from the multiple fitting points to the initialization correction point, and extracting the first fitting point with the farthest distance; step S234, adding the first fitting point to the immediate response correction mechanism and updating the simulation results through the conveyor belt simulation model, and so on, until the updated simulation results show that the deviation frequency of all points is less than the preset frequency.

[0031] Preferably, in the feed belt simulation model, an immediate response correction mechanism is set for the determined initialization correction point (such as the end of the belt or the beginning and the end). The immediate response correction mechanism simulates the behavior of the actual correction device to immediately correct the belt when it detects that the belt is deviating, ensuring that the belt can quickly return to the correct running track. The simulation model with the immediate response correction mechanism is used to perform multiple belt operation simulations to observe whether the belt will still deviate under different operating conditions, as well as the frequency and degree of deviation. In the simulation results, all multiple points with a deviation frequency higher than the preset frequency are recorded, that is, multiple fitting points. These fitting points are positions where the belt is prone to deviation under specific conditions. The preset frequency refers to a threshold value of the frequency or number of belt deviations in the feed belt simulation operation, which is used to measure the severity of the belt deviation problem and serve as a basis for whether the correction mechanism needs to be optimized and adjusted.

[0032] Preferably, the distance between these fitting points and the initialization correction point is calculated, and the one farthest from the initialization correction point is extracted as the first fitting point. The selection of this point is based on the assumption that if the farthest point can be effectively corrected, then other closer points should also be able to be better controlled; the first fitting point is added to the immediate response correction mechanism, that is, a correction device is also set at this point or the parameters of the existing device are adjusted, and the simulation model is used again to simulate and observe whether the updated correction mechanism can reduce the deviation frequency of the point, and then repeat the above steps, that is, after each simulation, new fitting points are collected, distances are calculated, the farthest point is extracted, the correction mechanism is updated, and simulation is performed again until the deviation frequency of all points is less than the preset frequency. It is considered that a relatively optimal correction point distribution has been found. By gradually optimizing the correction point distribution and the correction mechanism efficiency in the feed belt simulation model, not only the accuracy and efficiency of the correction device are improved, but also the impact of belt deviation on production efficiency and safety is reduced.

[0033] Step S300 , configuring a plurality of correcting devices at a plurality of points according to the optimal correcting point distribution, wherein any correcting device includes a conductive roller, a micro generator, and an electric push rod.

[0034] Preferably, multiple correction devices are configured at multiple points according to the optimal correction point distribution, which means that at each determined optimal correction point, a corresponding correction device is installed and configured to monitor the running status of the belt in real time and make timely adjustments when the belt deviates, so as to ensure that the belt always maintains a stable and accurate position during transportation. Specifically, each correction device includes a conduction roller, a micro generator and an electric push rod to achieve effective control and prevention of belt deviation problems. Among them, the conduction roller is one of the core components of the correction device, which is usually in direct contact with the belt and is used to sense the running status and position information of the belt and adjust it during the belt operation process. In the correcting device, the conductive roller senses the belt's deviation in real time and transmits this information to the micro-generator. The micro-generator, an energy conversion component in the correcting device, uses the belt deviation information transmitted by the conductive roller to convert it into electrical or mechanical energy to drive the electric push rod for correction, ensuring that it can quickly and accurately respond and generate sufficient corrective force when the belt deviates. The electric push rod is the actuator in the correcting device. Based on the signal and energy provided by the micro-generator, it pushes the conductive roller or related mechanical structure through telescopic movement, thereby correcting the belt's deviation and ensuring that it can be quickly and accurately corrected to its normal position when the belt deviates. The conductive roller, micro-generator, and electric push rod in each correcting device work together to achieve real-time monitoring and precise correction of belt deviation, thereby ensuring the stable operation and efficient production of the belt conveyor.

[0035] Furthermore, step S300 also includes step S310, wherein the conductive roller includes a first conductive roller and a second conductive roller, which are symmetrically distributed on both sides of the belt at the multiple points; step S320, the electric push rod includes a first push rod and a second push rod, which are symmetrically distributed on both sides of the belt at the multiple points; step S330, the conductive roller serves as a power source, is connected to the micro generator to form a power generation module, and provides electrical energy to drive the electric push rod.

[0036] Preferably, the conductive rollers include a first conductive roller and a second conductive roller, located symmetrically on either side of the belt, for real-time sensing of the belt's operating status, particularly belt deviation. When the belt deviates, the conductive rollers rotate or deviate accordingly, and this mechanical motion can be converted into electrical energy or other forms of energy for subsequent deviation correction. The electric push rods include a first push rod and a second push rod, also located symmetrically on either side of the belt, corresponding to the conductive rollers. The electric push rods serve as actuators of the deviation correction device, performing telescopic motion based on received control signals, thereby pushing or pulling the belt back to its correct position. The conductive rollers are connected to a micro-generator to form a power generation module, wherein the mechanical motion of the conductive rollers during belt operation can serve as a power source for generating electricity. When the belt deviates, the conductive rollers rotate accordingly, transmitting the mechanical energy generated by the conductive rollers' rotation to the micro-generator, which converts this mechanical energy into electrical energy to drive the electric push rods for deviation correction. This forms a closed-loop deviation correction device, where belt deviation causes the conductive rollers to rotate, and the electrical energy generated by this rotation drives the electric push rods for deviation correction, thereby maintaining stable belt operation.

[0037] Step S400 , monitoring the belt deviation at the plurality of points through the conductive rollers in the plurality of deviation correcting devices, generating offset points and corresponding belt deviation vectors, as well as corresponding target deviation correcting devices.

[0038] Preferably, the belt deviation is monitored at multiple corresponding points through the conduction rollers in each correcting device. That is, when the belt deflects during transmission, the conduction rollers at the deflection points capture the belt deviation information in real time, including the direction and degree of deflection, to generate the deflection point and the belt deviation vector. Specifically, the deflection point refers to the specific location where the belt deflects, and the belt deviation vector describes the direction and degree of belt deviation. After determining the deflection point and the belt deviation vector, the target correcting device that needs to be activated is finally determined to correct the belt deviation. The target correcting device is usually a device located near the deflection point or that can most effectively correct the belt deviation, thereby improving the operating efficiency and safety of the belt conveyor and reducing problems such as equipment damage and material spillage caused by belt deviation.

[0039] Furthermore, step S400 also includes step S410, establishing multiple groups of preset deviation vector samples; step S420, operating the conduction roller with the multiple groups of preset deviation vector samples, and obtaining multiple groups of rotation sensor samples through the rotation sensor test inside the conduction roller; step S430, wherein any group of rotation sensor samples includes rotation speed and rotation direction; step S440, establishing a deviation identification model based on the mapping relationship between the multiple groups of preset deviation vector samples and the multiple groups of rotation sensor samples; step S450, monitoring the belt deviation according to the rotation sensor inside the conduction roller through the deviation identification model, and generating the offset point and the belt deviation vector.

[0040] Ideally, when the conveyor belt is operating normally, the conductive roller maintains a certain distance from or slight contact with the belt edge, ensuring the conveyor belt follows its predetermined trajectory. However, if the conveyor belt deviates, one or both sides of the belt may excessively contact the conductive roller. When the belt deviates, the friction between the belt and the conductive roller increases, pushing the conductive roller to rotate in the direction of the belt's motion. The rotational speed and direction of the conductive roller can reflect the degree and direction of the belt's deviation.

[0041] Preferably, based on the historical data of the target belt conveyor, multiple sets of preset deviation vector samples are established, representing the possible deviation conditions (deviation direction and degree) of the belt under different conditions. Then, based on the multiple sets of preset deviation vector samples, the belt displacement is simulated and the conduction roller in the deviation correction device is operated in real time. At the same time, key information such as the rotation speed and rotation direction of the conduction roller is recorded in real time to form multiple sets of rotation sensing samples. Each set of rotation sensing samples should include two key parameters, rotation speed and rotation direction. These parameters can reflect the rotation condition of the conduction roller when the belt is deviated. Then, based on the machine learning model (such as decision tree, random forest, neural network, etc.), the belt is deviated. The recognition model is constructed by using a plurality of preset deviation vector samples as training input and a plurality of rotation sensor samples as training output. The recognition model is supervised and trained to learn the correlation between the belt deviation and the rotation of the conduction roller. The deviation recognition model is trained and established. During the actual operation, the rotation sensor inside the conduction roller will capture the deviation information of the belt in real time and input it into the deviation recognition model. The trained deviation recognition model is applied to the actual belt deviation monitoring. The deviation recognition model outputs the current offset point and belt deviation vector according to the input belt deviation information, so as to realize real-time monitoring and accurate identification of the operation status of the belt conveyor.

[0042] Step S500 , performing a deviation balance analysis on the electric push rod of the target deviation correction device using the belt deviation vector to generate a balance correction control vector.

[0043] Preferably, the belt deviation vector refers to the direction and degree of deviation of the belt from the normal position during operation, including the direction of belt deviation (such as left or right) and the degree of deviation (such as the distance or angle of deviation). The electric push rod is a key component in the correction device, responsible for adjusting the position of the belt according to the control signal. The electric push rod is usually composed of a motor, a reducer, a push rod and other components. The push rod can be driven by the motor to achieve telescopic movement, thereby adjusting the position of the belt. The deviation balance analysis refers to analyzing how the electric push rod needs to move to achieve belt deviation correction based on the belt deviation vector. Specifically, with the running load of the belt as a constraint condition, the direction and distance that the electric push rod needs to be extended and retracted are determined according to the direction and degree of belt deviation. The response speed of the electric push rod is adjusted according to the running speed and deviation of the belt to ensure the timeliness and accuracy of the correction, and then a balance guidance control vector is generated, which includes the action instructions that the electric push rod needs to execute, such as the extension direction, extension distance, response speed, etc. By inputting these instructions into the control system of the correction device, the electric push rod can be controlled to achieve belt deviation correction.

[0044] Furthermore, step S500 also includes step S510, collecting multiple groups of belt correction samples for the feed belt based on the running load as a constraint, and any group of belt correction samples includes a deviation vector sample and a corresponding balance correction control vector sample; step S520, training a correction control model with the multiple groups of belt correction samples; step S530, performing a deviation balance analysis on the belt deviation vector through the correction control model to generate the balance correction control vector.

[0045] Preferably, taking the operating load as a constraint, multiple groups of belt correction samples are collected for the feed belt to ensure that they are carried out under different operating load conditions to fully reflect the belt's correction characteristics under different loads. Each group of samples should include a deviation vector sample and a corresponding balance correction control vector sample, wherein the deviation vector sample describes the deviation direction and degree of the belt at a certain moment, and the balance correction control vector sample describes the action instructions that the electric push rod needs to execute in order to correct the deviation; a control model is constructed based on a machine learning model (such as a neural network, a support vector machine, etc.), with multiple groups of belt deviation vectors as training inputs and multiple groups of balance correction control vector samples as training outputs, and supervised training is performed on the control model to learn the correlation between belt deviation and correction action from the sample data. To the correction control model, the correction control model can accept the new belt deviation vector as input and output the corresponding balance correction control vector. The output balance correction control vector will guide the electric push rod of the correction device on how to move to correct the belt deviation; when the belt deviates, the belt deviation vector is analyzed for deviation balance through the correction control model. Based on the results of the deviation balance analysis, the correction control model generates a balance correction control vector, which includes the control instructions required to adjust the belt position, such as the extension direction, distance and speed of the electric push rod. By inputting this control vector into the control system of the correction device, real-time correction control of the belt can be achieved, thereby improving the operating efficiency and stability of the belt conveyor, and reducing equipment damage and material spillage caused by belt deviation.

[0046] In step S600 , a power generation module is established using the conductive roller and the micro-generator of the target deviation correction device to drive the corresponding electric push rod to correct the deviation according to the balance and guidance control vector.

[0047] Preferably, a power generation module is established with the conduction roller and micro-generator of the target correction device, and the mechanical energy generated by the rotation of the conduction roller is transmitted to the micro-generator, which uses this mechanical energy to generate electricity, thereby providing the required electrical energy for the electric push rod, and then driving the corresponding electric push rod to adjust the position of the belt through telescopic movement. Specifically, during the belt correction process, the electric push rod drives the electric push rod to perform telescopic movement according to the instructions in the balance guide control vector (guiding the electric push rod in what way and at what speed to perform telescopic movement). By precisely controlling the telescopic distance and speed of the electric push rod, real-time monitoring of the belt position and precise correction adjustment are achieved, which not only improves the operating efficiency and stability of the belt conveyor, but also reduces energy consumption and maintenance costs.

[0048] Furthermore, step S600 also includes step S610, and the target correction device also includes an inverter rectifier controller; in step S620, the conduction roller of the target correction device rotates to drive the micro-generator to generate electrical energy, and the inverter rectifier controller sends a control signal according to the balance correction control vector; in step S630, the control signal is used to control the corresponding electric push rod to correct the deviation.

[0049] Preferably, the target correction device further includes an inverter rectifier controller. The micro generator is combined with the conductive roller to generate electricity using the mechanical energy generated by the rotation of the conductive roller. However, the electric energy generated by the micro generator may be alternating current (AC) or unstable direct current (DC). The inverter rectifier controller is used to convert this unstable electric energy into stable and usable direct current (DC) or to invert and convert it into alternating current (AC) as needed for use by the electric push rod. The inverter rectifier controller is not only responsible for the conversion of electric energy, but also sends corresponding control signals according to the balance and correction control vector (calculated by the correction control model). These control signals contain the action instructions that the electric push rod needs to execute, such as the extension direction, extension distance, response speed, etc. The control signals are used to control the corresponding electric push rod to correct the deviation. After the control system of the electric push rod receives the control signal from the inverter rectifier controller, it will parse these signals and act according to the instructions in the signal. That is, the electric push rod will extend and retract according to the instructions in the control signal, adjust the position of the belt and accurately control the extension distance and speed of the electric push rod, so as to correct the belt deviation and restore the belt to normal operating state, thereby improving the operating efficiency and stability of the belt conveyor.
