Abstract
Description
Technical Field
[0001] This invention relates to the field of conveyor belt technology, specifically to a conveyor belt alignment device and a conveyor belt alignment processing method. Background Technology
[0002] With the continuous improvement of industrial production capacity, the technical level of conveying tools is also constantly improving. Pipe belt conveyors, with their unique advantages, are increasingly widely used in the continuous conveying of various bulk materials. The materials being conveyed are surrounded within the cylindrical conveyor belt, preventing them from easily spilling and meeting the trend of environmentally friendly conveying.
[0003] At the belt forming section of a conveyor belt system, two guide rollers are typically used to press down on one side of the belt to ensure reliable belt overlap. If the overlap changes or misaligns during belt operation, the belt will run off-track when it reaches the unfolding section, causing numerous adverse effects.
[0004] In existing technologies, there are two main types of methods for detecting belt conveyor misalignment: one is the direct contact detection method, which causes wear on the belt and affects its service life. The other is the non-contact detection method. Among these, the imaging detection method based on image processing and analysis has blind spots in the imaging area, resulting in incomplete data collection and inaccurate image processing and analysis results. Furthermore, deploying numerous imaging devices significantly increases equipment costs. The laser probe scanning method, on the other hand, is highly sensitive to environmental conditions. The harsh outdoor working environment of the conveyor belt can significantly affect the laser probe, especially the unavoidable interference from natural light, leading to false detections and inaccurate results.
[0005] In view of this, it is urgent to optimize and improve the correction method of the conveyor belt to effectively avoid the impact of belt misalignment. Summary of the Invention
[0006] To address the aforementioned technical problems, this invention provides a belt conveyor correction device and a belt conveyor correction processing method, which can adapt to the working environment requirements of the belt conveyor and, while improving the accuracy of signal acquisition, provides technical support for avoiding the impact of belt misalignment.
[0007] The present invention provides a belt conveyor belt alignment device for forming circular segments of conveyor belt.

An angle sensor is used to detect the rotation angle of the driving component. A first ultrasonic sensor is mounted on the driven gear ring disk, with its probe end facing the conveyor belt. The fixed plate assembly includes a plate body, and a second ultrasonic sensor, a force sensor, and a correction assembly mounted on the plate body. The plate body is connected to the truss and has a central through hole. The probe end of the second ultrasonic sensor faces the conveyor belt, and the force sensor is used to detect the bearing pressure of the correction roller of the correction assembly.
[0008] Optionally, the chassis includes a first disc and a second disc that are detachably connected, and the two together form the central through hole. The first disc is detachably connected to the truss. The driven gear annular disc includes a first gear disc and a second gear disc. The first gear disc is detachably connected to the truss.
[0009] Optionally, the detection ends of the first ultrasonic sensor and the second ultrasonic sensor are respectively positioned opposite to the overlap of the tape.
[0010] Optionally, the correction assembly includes a correction roller, an electric push rod, and a swing rod. The electric push rod and the swing rod are located on one side of the plate, and the correction roller is located on the other side of the plate. One end of the electric push rod is rotatably mounted on the plate, and the other end of the electric push rod is rotatably connected to the swing rod. The swing rod passes through the plate and is connected to the correction roller.
[0011] Optionally, the force sensor is located below the correction roller, and the electric push rod is rotatably connected to a support fixed on the plate.
[0012] The belt conveyor deviation correction method provided by this invention employs the belt conveyor deviation correction device as described above, and includes the following steps: In the test operation state of the belt conveyor, based on data collected by the first ultrasonic sensor, angle sensor, second ultrasonic sensor, and force sensor, a ridge regression algorithm model for the belt deviation angle is obtained using ridge regression analysis; In the actual operation state of the belt conveyor, based on data collected by the second ultrasonic sensor and the force sensor, the current belt deviation angle is obtained using the ridge regression algorithm model, and a control command is output to the control terminal of the deviation correction component based on the current belt deviation angle.
[0013] Optionally, during the test operation of the conveyor belt machine, an external force is applied to the conveyor belt using a redirection component. After the overlap position of the conveyor belt changes, a ridge regression algorithm model for the conveyor belt deviation angle is obtained based on data collected by the first ultrasonic sensor, angle sensor, second ultrasonic sensor, and force sensor, and on the ridge regression analysis algorithm.
[0014] The present invention also provides a conveyor belt machine, including a truss and a conveyor belt, and further including a fixing plate assembly and a host computer; the fixing plate assembly is disposed at the location of the circular segment of the truss, and the fixing plate assembly includes a plate body, and a second ultrasonic sensor, a force sensor and a correction assembly disposed on the plate body; the plate body is connected to the truss and has a through hole in the middle; the detection end of the second ultrasonic sensor is disposed facing the conveyor belt, and the force sensor is used to detect the bearing pressure of the correction roller of the correction assembly; the host computer outputs control commands to the control terminal of the correction assembly based on the distance value to the conveyor belt measured by the second ultrasonic sensor and the pressure value detected by the force sensor.
[0015] Optionally, the detection end of the second ultrasonic sensor is positioned opposite to the overlap of the tape.
[0016] Optionally, the correction assembly includes a correction roller, an electric push rod, and a swing rod. The electric push rod and the swing rod are located on one side of the plate, and the correction roller is located on the other side of the plate. One end of the electric push rod is rotatably mounted on the plate, and the other end of the electric push rod is rotatably connected to the swing rod. The swing rod passes through the plate and is connected to the correction roller.
[0017] Compared with existing technologies, this solution proposes a novel approach to belt conveyor belt deviation correction. Specifically, the belt conveyor deviation correction device includes a redirection assembly, a rotating disk assembly, and a fixed plate assembly. The redirection assembly applies external force to the conveyor belt to change its overlap position, providing data for model building. The rotating disk assembly's drive component, drive gear, driven gear ring disk, angle sensor, and first ultrasonic sensor are mounted on the chassis. The first ultrasonic sensor's probe faces the conveyor belt, and the deviation position of the conveyor belt overlap is determined by detecting the shortest distance. The deviation angle is then calculated based on the angle sensor's measurement and the gear ratio. The fixed plate assembly's second ultrasonic sensor, force sensor, and deviation correction assembly are mounted on the plate. The second ultrasonic sensor's probe faces the conveyor belt, and the force sensor detects the bearing pressure of the deviation correction rollers, providing data for the algorithm model. This solution utilizes ultrasonic probes to detect conveyor belt overlap without contact, preventing damage to the belt. It also adapts to the working environment of conveyor belt systems, exhibits strong anti-interference capabilities, and ensures the accuracy of the collected data. Furthermore, this solution combines the pressure change of the idler roller measured by the force sensor with the distance to the overlap measured by the ultrasonic sensor to calculate the belt overlap deviation angle. This increases the independent variable for calculating the deviation angle, resulting in more comprehensive detection data and providing more theoretical basis for subsequent algorithm analysis.
[0018] In an optional embodiment of the present invention, the chassis includes a first disc body and a second disc body that are detachably connected, and the two together form a central through hole. The first disc body is detachably connected to the truss. The driven gear annular disc includes a first gear disc and a second gear disc, and the first gear disc is detachably connected to the truss. This configuration facilitates on-site installation and is applicable to the detection of belt conveyor misalignment in different projects, improving applicability while reasonably reducing equipment costs.
[0019] The belt conveyor deviation correction method provided by this invention, under test operation conditions, obtains a ridge regression algorithm model for the belt deviation angle based on data collected by a first ultrasonic sensor, an angle sensor, a second ultrasonic sensor, and a force sensor, using ridge regression analysis. Under actual operation conditions, obtains the current belt deviation angle based on data collected by the second ultrasonic sensor and the force sensor, using the ridge regression algorithm model, and outputs control commands to the control terminal of the deviation correction component based on the current belt deviation angle. This setup, using ridge regression analysis to train the model, ensures the reliability of the belt deviation calculation and avoids the false detection or inaccurate detection that occurs with traditional deviation angle sensors.

[0032] Pipe conveyor truss 40;
[0033] 50g of tape. Detailed Implementation
[0034] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] Please see Figure 1This figure is a schematic diagram of the assembly relationship of a belt conveyor correction device according to an embodiment of this application. The overall structure of the belt conveyor correction device is shown in the figure to clearly illustrate its purpose. Figure 1 The image only shows a portion of the conveyor structure at its installation location.
[0036] like Figure 1 As shown, the belt conveyor correction device includes a redirection assembly 10, a rotary disk assembly 20, and a fixing plate assembly 30, all fixedly mounted on the belt conveyor truss 40. The redirection assembly 10 can be installed at any truss position corresponding to the circular segment of the conveyor belt. The rotary disk assembly 20 and the fixing plate assembly 30 are sequentially and alternately fixed at the truss positions of the circular segment. Furthermore, the redirection assembly 10, rotary disk assembly 20, and fixing plate assembly 30 are respectively fitted onto the outside of the conveyor belt 50. Please refer to [further details omitted]. Figure 2 The image is Figure 1 The diagram shows the assembly relationship between the rotating disk assembly, the fixed plate assembly, and the tape.
[0037] The redirecting component 10 is manually operable; by deflecting the idler roller 11 of the redirecting component 10, the conveyor belt 50 can be misaligned. Please refer to [link / reference]. Figure 3 This figure is a schematic diagram of one usage state of the reversing component 10 provided in an embodiment of this application.
[0038] Specifically, by manually operating the knob 14, which is linked to the drive gear 12 of the redirection assembly 10, the drive gear 12 rotates, causing multiple driven gears 13 meshing with it to rotate synchronously. Each driven gear 13 drives the connected idler roller 11 to change direction, thereby driving the conveyor belt 50 to deviate during operation. In practice, this redirection assembly 10 can be implemented using existing technology, so it will not be described in detail here.
[0039] The rotating disk assembly 20 includes a chassis 21, a drive component 22, a drive gear 23, a driven gear ring disk 24, an angle sensor 25, and a first ultrasonic sensor 26. (See also...) Figure 4 The figure is a schematic diagram of the structure of the rotating disk assembly provided in the embodiment of this application.
[0040] The chassis 21 is the basic assembly structure of the rotating disk assembly 20, fixedly mounted on the conveyor truss 40, and has a central through hole for fitting over the conveyor belt 50. The drive component 22 is fixedly mounted on the chassis 21, and the drive gear 23 is connected to the output end of the drive component 22. The driven gear ring disk 24, meshing with the drive gear 23, is rotatably mounted on the chassis 21. Thus, the drive component 22 drives the drive gear 23 to rotate, which in turn drives the driven gear ring disk 24 to rotate.
[0041] The drive component 22 can be a servo motor, and the angle sensor 25 is mounted on the drive component 22, for example, but not limited to, on the servo motor shaft, to detect its rotation angle. The first ultrasonic sensor 26 is mounted on the driven gear annular disk 24, with its detection end facing the tape 50, specifically located above the overlap edge of the tape 50. Please refer to [further details omitted]. Figure 5 The figure shows the relative positional relationship between the first ultrasonic sensor 26 and the overlap of the tape 50.
[0042] Here, the distance L from the first ultrasonic sensor 26 to the tape overlap area A is the shortest. By detecting this shortest distance, the tape overlap deviation position is determined, and the tape deviation angle is calculated based on the angle sensor measurement and the gear transmission ratio. That is, when the tape 50 is running in the correct position, the distance between its overlap position and the first ultrasonic sensor 26 is at its minimum. When the tape deviates, the distance from the first ultrasonic sensor 26 to other positions on the tape changes. Specifically, the drive component 22 can drive the driven gear ring disk 24 to rotate until the first ultrasonic sensor 26 detects the tape overlap area A. At this time, the angle sensor 25 can detect the current angle and accurately determine the tape overlap deviation position based on the detected angle data.
[0043] For ease of installation, the chassis 21 and the driven gear ring disk 24 can be designed as separate, detachable structures.
[0044] For example Figure 4 As shown, the chassis 21 includes a first disc body 211 and a second disc body 212, which are detachably connected by a first connecting plate 213 and threaded fasteners, and together form a central through hole. In a specific implementation, the second disc body 212 is located below the first disc body 211 and can be connected to the conveyor truss 40 through the first disc body 211, for example, but not limited to, using threaded fasteners to achieve a detachable connection between the chassis 21 and the conveyor truss 40.
[0045] In other possible implementations, the detachable connection between the first disc 211 and the second disc 212 can also adopt other structural forms; for example, the connection parts of the second disc 212 and the first disc 211 can overlap and be connected by threaded fasteners. This application does not limit the scope of the embodiments.
[0046] The driven gear annular disk 24 includes a first gear disk 241 and a second gear disk 242, which are detachably connected by a second connecting plate 243 and threaded fasteners, and together form the driven gear annular disk 24.
[0047] The fixed plate assembly 30 includes a plate body 31 and detection and correction components mounted on the plate body 31. Please refer to [the documentation for further details]. Figure 6 and Figure 7,in, Figure 6 This is a schematic diagram of the structure of the fixing plate assembly 30 provided in the embodiments of this application. Figure 7 For self Figure 6 This is a schematic diagram of the fixed plate assembly 30 as shown from another angle.
[0048] The plate 31 is the basic assembly structure of the fixed plate assembly 30, and is fixedly installed on the pipe conveyor truss 40. The plate 31 has a through hole in the middle to fit over the tape 50.
[0049] For ease of installation, the plate 31 can also adopt a split, detachable structure. The plate 31 includes a first plate 311 and a second plate 312, such as... Figure 7 As shown, the two are detachably connected by a third connecting plate 313 and threaded fasteners, forming a central through hole. In a specific implementation, the second plate 312 is located below the first plate 311 and can be connected to the conveyor truss 40 through the first plate 311.
[0050] The detection assembly includes a second ultrasonic sensor 32 and a force sensor 33. The second ultrasonic sensor 32 is used to detect the distance to the tape 50. The second ultrasonic sensor 32 is disposed on the plate 31 and its detection end is positioned facing the tape 50, specifically above the overlap position of the tape 50. The force sensor 33 is used to detect the pressure data of the straightening roller 34. The force sensor 33 is disposed below the straightening roller 34.
[0051] The correction assembly includes a correction roller 34, an electric push rod 35, and a swing rod 36. The electric push rod 35 and the swing rod 36 are located on one side of the plate 31, and the correction roller 34 is located on the other side of the plate 31. One end of the electric push rod 35 and the other end of the electric push rod 35 are rotatably connected to the swing rod 36. The swing rod 36 passes through the plate 31 and is connected to the correction roller 34 to drive the correction roller 34 to rotate.
[0052] In this way, after receiving the correction command, the electric push rod 35 actuates, driving the swing rod 36 and the correction roller 34 connected to the swing rod 36 to rotate, thus completing the belt correction action. In specific implementations, this correction component can be implemented using existing technology, so it will not be described in detail here.
[0053] When the conveyor belt deviates from its designated path, the distance to the conveyor belt 50 and the pressure value carried by the correction roller 34 can be detected in real time. These values serve as the training and testing sets for the algorithm model and are then applied to the actual operation of the conveyor belt conveyor.
[0054] In practical implementation, this correction component can add correction levels to the existing correction device, selecting the action level of the electric push rod 35 according to the range of tape deviation angle. For example, but not limited to, the threshold for tape deviation angle is 45°. When the left / right deviation angle of tape 50 exceeds 45°, the first-level correction is activated; otherwise, the second-level correction is activated.
[0055] The conveyor belt alignment device provided in this application utilizes an ultrasonic probe to detect the belt overlap, achieving contactless detection without damaging the belt. It is adaptable to the working environment of the conveyor belt machine, possesses strong anti-interference capabilities, and ensures the accuracy of the collected data. Furthermore, this solution combines the pressure change of the idler roller measured by the force sensor with the distance to the overlap measured by the ultrasonic sensor to calculate the belt overlap deviation angle. This increases the independent variable for calculating the deviation angle, resulting in more comprehensive detection and data collection, and providing more theoretical basis for subsequent algorithm analysis.
[0056] The following is combined with Figure 8 The flowchart of the conveyor belt deviation correction system shown below briefly illustrates the conveyor belt deviation detection method based on algorithm analysis:
[0057] First, under the test operation state of the conveyor belt machine, based on the data collected by the first ultrasonic sensor, the angle sensor, the second ultrasonic sensor and the force sensor, a ridge regression algorithm model for the belt deviation angle is obtained based on the ridge regression analysis algorithm.
[0058] Specifically, the reversing component 10 is activated, allowing the application of any magnitude and direction of external force to change the overlap position of the tape. Once the overlap position changes, the drive component 22 is activated, causing the driving gear 23 to rotate the driven gear ring disk 24. The first ultrasonic sensor 26 moves synchronously. Based on the shortest distance from the probe of the first ultrasonic sensor 26 to the overlap position of the tape 50, when the distance detected by the probe changes abruptly from high to low, the current overlap position of the tape can be determined. At this time, the deviation angle θ of the tape 50 is calculated and recorded based on the measured value θ1 of the angle sensor 25 on the drive component 22 and the gear transmission ratio i (the transmission ratio between the driving gear 23 and the driven gear ring disk 24).
[0059] At the same deviation angle, data measured by the second ultrasonic sensor 32 and force sensor 33 on multiple (k) sets of fixed plate assemblies 30 are read in real time. Specifically, the data includes the distance value L measured by the second ultrasonic sensor 32 and the pressure value F measured by the force sensor 33. The data acquisition process is illustrated as follows: Figure 2 As shown.
[0060] In practice, invalid data can be removed and mean value analysis can be performed to obtain the mean distance Lm and the mean pressure Fm, as shown in Formula 1 below:
[0061]
[0062] By applying an external force of arbitrary magnitude and direction again through the reversing component 10, and repeating this process multiple times, the distance value L and pressure value F at different deviation angles θn are sampled to obtain the average distance value Lmn and the average pressure value Fmn.
[0063] Furthermore, to avoid overfitting, a penalty term coefficient is added to the loss function of the multiple linear regression, and a new structural risk function is obtained according to the following formula 2.
[0064]
[0065] Where ω is the value of the ridge regression fitting loss function; β j λ is the penalty coefficient for the j-th feature out of p features; x and y are the independent and dependent variables of the multiple linear regression fitting function (the dependent variable is the deviation angle θ in Formula 3 below, and the independent variables are the distance value L and the pressure value F); λ is the regularization coefficient, used to adjust the penalty intensity of the parameters; n is the number of independent variables; p is the number of features.
[0066] Then, the deviation angle θn, distance value Lmn, and pressure value Fmn of the detection data are used as input data for the training and test sets. Ridge regression analysis is adopted, and after introducing the ridge algorithm for modeling, the training set data is simulated to reduce the complexity of the model. The optimal regression parameters β0, β1, and β2 that minimize the loss function value ω are selected to obtain the ridge regression model shown in Formula 3 below:
[0067] θ=β0+β1L+β2F (Formula 3)
[0068] After obtaining the algorithm model, the distance value Lmn and pressure value Fmn from the test set data are used as input data and substituted into the ridge regression model to calculate the deviation angle θ for cross-validation. Based on this, the performance of the trained model on the detection data during actual operation is evaluated. Once the accuracy reaches a preset value, the final regression model is determined. This setup, using the ridge regression analysis algorithm to train the model, ensures the reliability of the tape deviation calculation and avoids the false detections or inaccuracies that occur with traditional deviation angle sensors.
[0069] After obtaining the final ridge regression algorithm model, it can be uploaded to the host computer (not shown in the figure), and then switched to automatic mode, meaning the reversing component is reset to its initial position. Of course, in actual implementation, after the model training is complete, the reversing component 10 can be removed from the conveyor truss 40.
[0070] Next, combined Figure 8Briefly explain the control method for conveyor belt misalignment based on algorithm analysis:
[0071] During actual operation of the conveyor belt conveyor, the detection device performs real-time measurements. Specifically, it measures the distance L measured by the second ultrasonic sensor 32 and the pressure F measured by the force sensor 33, transmitting the collected data to the host computer. The system automatically calculates the belt misalignment angle θ using a ridge regression model. In practice, all data can be displayed and stored in real time.
[0072] When the calculated current belt deviation angle is within the allowable torsional angle range θm (e.g., θm is 30°), it indicates that the conveyor belt in the detection area is not deviated, and the correction component does not activate. When the calculated belt deviation angle exceeds the allowable torsional angle range θm, control commands are issued to the correction component according to the correction action level corresponding to the current deviation angle. For example, when the left / right deviation angle of the belt exceeds 45°, level one correction is activated; otherwise, level two correction is activated (exceeding 30° but not exceeding 45°), and the electric push rod activates accordingly. In other words, different amplitude action commands are output under different correction threshold levels. In this way, by issuing commands based on the action level of the correction system according to the algorithm model analysis, more reliable and efficient correction actions are achieved.
[0073] In other possible implementations, the level of correction action is not limited to the two-level correction action described in the aforementioned example, and can be determined according to the overall design requirements. This application's embodiments do not impose such limitations.
[0074] It should be noted that, in the specific implementation, the fixed plate assembly 30 can be set according to the actual needs of the application scenario, and can be installed at any position of the tube conveyor forming the circular segment.
[0075] In addition to the aforementioned belt conveyor correction device, this application embodiment also provides a belt conveyor, which includes a belt conveyor truss 40 and a belt 50, as well as a host computer and a fixing plate assembly 30 as described above. The fixing plate assembly 30 is disposed on the belt conveyor truss 40 in the circular section of the belt conveyor, and its plate body is fitted outside the belt 50.
[0076] It should be understood that the specific implementation of the pipe conveyor truss 40, the conveyor belt 50 and other functional components of the pipe conveyor is not the core inventive point of this application, and those skilled in the art can implement it based on the prior art, so it will not be described in detail here.
[0077] It should be noted that the ordinal numbers "first" and "second" used in this embodiment are only for clarifying the technical composition and relationships, and the use of the above ordinal numbers does not constitute a substantial limitation on the technical solution described in this application.
[0078] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
