Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more specifically to a belt conveyor correction system. Background Technology

[0002] Most existing conveyor belt correction systems use eccentric rollers to adjust the belt alignment. These rollers detect belt misalignment, and when misalignment is detected, the belt friction on the misaligned side of the roller increases, forcing the roller on the misaligned side to rotate around the roller's axis, thus moving the belt towards the center line of the conveyor and correcting the belt alignment.

[0003] Chinese patent application CN 120348636 A discloses an automatic conveyor belt alignment device, which includes a horizontally arranged frame for supporting the conveyor belt; a pressure detection unit including two rows of pressure detectors symmetrically arranged along the width direction of the conveyor belt; double-row inclined conveyor rollers symmetrically mounted on the frame via supports with rotational damping and in contact with the lower surface of the conveyor belt; an adjustable support assembly including a top block slidably disposed on the conveyor roller; and a control unit electrically connected to the pressure detection unit, including a comparison module and a signal output module; wherein, when the comparison module detects a pressure difference between the two sides of the same position on the conveyor belt, the signal output module sends a drive signal to the adjustable support assembly corresponding to the side with lower pressure, causing the top block to extend out of the surface of the conveyor roller.

[0004] However, existing conveyor belt correction systems use contact testing, which only works when the conveyor belt deviates to the sensor, making real-time correction impossible. Furthermore, multiple correction devices are required to achieve correction, resulting in low efficiency and high cost. If the conveyor belt keeps deviating to the sensor without making contact, the conveyor belt correction system cannot detect the deviation during long-term operation, causing the conveyor to operate in a deviated state for an extended period.

[0005] Therefore, how to effectively improve the correction efficiency of conveyors and ensure stable and reliable correction has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a high-efficiency, stable and reliable belt conveyor correction system and method.

[0007] To achieve the above objectives, the present invention provides a belt conveyor alignment system, including a conveyor base and further comprising...

[0008] The guiding rollers are distributed below the return conveyor belt, slidably connected to the conveyor base, and rotatable on the conveyor base.

[0009] Data acquisition components, distributed around the guiding roller, are configured to acquire images of the conveyor belt in real time.

[0010] A controller, connected to the data acquisition component, is configured to perform fitting processing based on the conveyor belt image to generate a conveyor belt edge fitting line, and to calculate and compare the conveyor belt edge fitting line with the conveyor belt baseline to generate a correction signal.

[0011] A drive mechanism configured to control the motion state of the correction roller in real time according to the correction signal.

[0012] Furthermore, it also includes a rotating mechanism, which is distributed at the bottom of the correction roller. The bottom surface of the rotating mechanism is slidably connected to the conveyor base, and the top surface cooperates with the correction roller.

[0013] Furthermore, the rotating mechanism is provided with sliding brackets at both ends, the top surface of the sliding bracket is provided with a mounting seat for cooperating with the straightening roller, and the bottom surface is provided with a pulley.

[0014] Furthermore, the conveyor base is provided with oppositely distributed rotating tracks at both ends. The rotating tracks are configured in an arc shape that protrudes outward from the conveyor base and are adapted to the pulleys.

[0015] Furthermore, proximity switches are provided at both ends of the rotating track.

[0016] Furthermore, the central region of the rotating mechanism is slidably connected to the conveyor base via a rotating base.

[0017] Furthermore, the data acquisition component includes four sets of camera devices respectively disposed at the four corners of the correction roller.

[0018] Furthermore, the controller extracts the conveyor belt edge pixels from the conveyor belt image, and performs collection, packing and array stacking processing on the conveyor belt edge pixels, calculates the correlation coefficient of the conveyor belt edge fitting line, and then calculates the slope and intercept of the conveyor belt edge fitting line through regression fitting processing to generate the conveyor belt edge fitting line.

[0019] Furthermore, the controller calculates the shortest distance between the fitted line of the conveyor belt edge and the baseline of the conveyor belt, and determines the shortest distance and a distance threshold to generate a correction signal.

[0020] To achieve the above objectives, the present invention provides a belt conveyor correction method, wherein the correction method acquires conveyor belt images in real time, generates conveyor belt edge fitting lines based on the conveyor belt images, calculates and compares the conveyor belt edge fitting lines with the conveyor belt baseline, generates a correction signal, controls the rotation of the correction roller in real time to adjust the conveyor belt deviation, and continuously acquires conveyor belt images in real time, dynamically updates the conveyor belt edge fitting lines and correction signals, and dynamically adjusts the conveyor belt deviation.

[0021] The belt conveyor correction system provided by this invention acquires images of the conveyor belt in real time, generates a fitted line of the conveyor belt edge, and calculates and compares it with the baseline of the conveyor belt. It can detect the offset state of the conveyor belt in real time without contact. Moreover, the fitted line of the conveyor belt edge can reflect the offset state of the conveyor belt throughout its entire length. Only one correction system needs to be set up on the conveyor to achieve precise monitoring of the overall running trajectory of the conveyor belt, thereby improving detection accuracy and reducing correction costs. At the same time, the controller can work with the drive mechanism to adjust the rotation of the correction roller in real time and dynamically according to the fitted line of the conveyor belt edge, achieving efficient and accurate active correction. This correction system not only significantly reduces the hardware cost of multi-point deployment, but also significantly improves the timeliness, effectiveness, and operational reliability of correction due to its single-point full-process monitoring and rapid response features.

[0022] Furthermore, the belt conveyor correction method provided by this invention continuously collects images of the conveyor belt in real time, dynamically updates the conveyor belt edge fitting line and correction signal, and dynamically adjusts the conveyor belt, enabling multiple fine adjustments of the conveyor belt and improving the correction accuracy.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0031] See Figure 1 The image shows an example of a belt conveyor correction system provided by the present invention.

[0032] As shown in the figure, the belt conveyor correction system in this example mainly includes a conveyor base 1, a correction roller 2, a data acquisition component 3, a controller 4, and a drive mechanism 5.

[0033] The correction roller 2 is located below the return conveyor belt, slidably connected to the conveyor base 1, and can rotate on the conveyor base 1. The data acquisition components 3 are distributed around the correction roller 1 and can acquire images of the conveyor belt in real time. The controller 4 can perform fitting processing based on the conveyor belt images to generate a conveyor belt edge fitting line, and calculate and compare the conveyor belt edge fitting line with the conveyor belt baseline to generate a correction signal. The drive mechanism 5 can control the movement state of the correction roller 2 in real time according to the correction signal to correct the conveyor belt in real time. Thus, the offset state of the conveyor belt can be detected in real time without contact. Moreover, only one correction system is needed to achieve accurate monitoring of the overall running trajectory of the conveyor belt, thereby improving detection accuracy and correction cost, and ensuring stable and reliable correction.

[0034] The correction roller 2 is mounted on the conveyor base 1 via a rotating mechanism 6. The rotating mechanism 6 is located at the bottom of the correction roller 2, with its bottom surface slidably connected to the conveyor base 1 and its top surface engaging with the correction roller 2, so that the rotating mechanism 6 can drive the correction roller 2 to rotate on the conveyor base 1.

[0035] Combination Figure 1 and Figure 2 Specifically, the central region of the rotating mechanism 6 is slidably connected to the conveyor base 1 via a rotating base 7, such as a turntable, so that the rotating mechanism 6 can rotate on the conveyor base 1 via the rotating base 7.

[0036] Furthermore, the rotating mechanism 6 is provided with sliding brackets 61 at both ends, and the top surface of the sliding brackets 61 is provided with mounting bases 611. The shaft 21 of the straightening roller 2 extends into the mounting base 611 and is connected to the mounting base 611, so that when the rotating mechanism 6 rotates on the conveyor base 1 through the rotating base 7, it can drive the straightening roller 2 to rotate synchronously through the mounting base 611.

[0037] To ensure the rotational stability of the straightening roller 2, the bottom of the sliding bracket 61 is provided with a pulley 612. Correspondingly, the two ends of the conveyor base 1 are provided with a rotating track 11 adapted to the pulley 612, so that the two ends of the straightening roller 2 can rotate along the rotating track 11 through the pulley 612, thereby improving the connection stability between the straightening roller 2 and the conveyor base 1.

[0038] As a preferred configuration, the bottom of the sliding bracket 61 is provided with two sets of relatively distributed limiting plates 613, so that a limiting cavity is formed between the two sets of limiting plates 613. The pulley 612 is slidably disposed in the limiting cavity, and the limiting plates 613 are distributed on both sides of the rotating track 11, so that the limiting plates 613 can cooperate with the rotating track 11 to limit the rotation of the pulley 612, ensuring that the straightening roller 2 will not deviate when rotating along the rotating track 11 through the pulley 612, thereby improving the rotational stability of the straightening roller 2.

[0039] Combination Figure 1 Furthermore, the rotating tracks 11 at both ends of the conveyor base 1 are relatively distributed and configured in an arc shape protruding outwards from the conveyor base 1, so that the rotating tracks 11 at both ends of the conveyor base 1 form a symmetrical concentric arc distribution protruding in opposite directions. This allows the two ends of the correction roller 2 to slide precisely in opposite directions along the rotating track 11 and always rotate around the rotating base 7 as the center, thereby enabling the correction roller 2 to rotate smoothly and stably, eliminating the risk of jamming or deviation, and improving rotational stability.

[0040] Meanwhile, the motion state of the correction roller 2 is strictly controlled. By controlling the rotation angle of the correction roller 2, the required correction force can be applied to the conveyor belt more effectively and reliably, thereby improving the correction effect.

[0041] Combination Figure 1 and Figure 2 In order to control the movement state of the correction roller 2, the system also includes a drive mechanism 5. The drive mechanism 5 is connected to the controller 4 so that the controller 4 can control the working state of the drive mechanism 5. The drive mechanism 5 is preferably composed of a motor reducer and is connected to the correction roller 2 through a push rod 51, so that the controller 4 can control the drive mechanism 5 to drive the push rod 51 to push the correction roller 2, so that the correction roller 2 rotates along the rotating track 11 with the rotating base 7 as the center in the direction of adjustment, thereby adjusting the conveyor belt.

[0042] Meanwhile, proximity switches 12 are provided at both ends of the rotating track 11. The proximity switches 12 are connected to the controller 4 so that when the two ends of the straightening roller 2 move to the extreme positions at the ends of the rotating track 11, they approach the proximity switches 12. The proximity switches 12 can generate a stop signal and transmit it to the controller 4. When the controller 4 receives the stop signal, it will control the working state of the drive mechanism 5, stop driving the rotation of the straightening roller 2, stop the straightening, and control the drive mechanism 5 to move in the opposite direction of the straightening to prevent the straightening roller 2 from leaving the rotating track 11, thus ensuring the stable and reliable operation of this straightening system.

[0043] In order to precisely adjust the rotation angle of the correction roller 2 so that the rotation angle of the correction roller 2 matches the amount of belt deviation, thereby improving the correction accuracy and efficiency, this correction system also includes a data acquisition component 3. The data acquisition component 3 can acquire images of the conveyor belt in real time and cooperate with the controller 4 to detect the belt deviation status in real time and precisely control the rotation angle of the correction roller 2 accordingly.

[0044] Combination Figure 1 Specifically, the data acquisition component 3 includes four sets of camera devices 31 respectively set at the four corners of the correction roller 2. As an example, the four sets of camera devices 31 can be composed of high-altitude AI cameras with high acquisition frequency, so that the four sets of camera devices 31 can synchronously and in real time acquire images of the conveyor belt of the conveyor section and transmit them to the controller 4.

[0045] In this way, the conveyor belt images obtained by the first camera device 311 and the second camera device 312 distributed on the first side of the straightening roller 2 can reflect the deviation of the first side of the straightening roller 2, and the third camera device 313 and the fourth camera device 313 distributed on the second side of the straightening roller 2 can reflect the deviation of the second side of the straightening roller 2, thereby comprehensively monitoring the deviation of the straightening roller 2.

[0046] Furthermore, the controller 4 can receive conveyor belt images, perform fitting processing based on the conveyor belt images to generate conveyor belt edge fitting lines, and then calculate and compare the conveyor belt edge fitting lines with the preset conveyor belt baseline to generate a correction signal that is transmitted to the drive mechanism 5, thereby precisely controlling the rotation angle of the correction roller 2 and improving the correction efficiency.

[0047] Specifically, the controller 4 first uses the Canny edge detection algorithm to extract the edge pixels of the conveyor belt images acquired by the four sets of camera devices 31, and then uses the least squares method to fit and generate the conveyor belt edge fitting line.

[0048] As an example, controller 4 first performs grayscale transformation on the conveyor belt image to obtain the grayscale image of the conveyor belt image, which is the pixel image of the conveyor belt image; then, it uses Gaussian convolution filtering to smooth the pixel image to eliminate noise interference; next, it performs first-order differentiation on the pixel image, uses an edge detection operator to convolve the smoothed pixel image, calculates the first-order derivative of each pixel in the horizontal and vertical directions, and then performs second-order partial derivatives to calculate the gradient value and direction of each pixel, in order to obtain the pixels with the most drastic brightness changes and directions in the pixel image. The process begins by locating the edge of the conveyor belt, where pixels undergo significant changes, thus initially identifying these edge pixels. Next, non-maximum suppression (NMS) is performed. Along the gradient direction of each pixel, the gradient value of that point is compared with the gradient values ​​of the pixels before and after it. If the gradient value of the current point is a local maximum along its gradient direction, that point is retained, thus preserving the local maximum along the gradient direction and generating a refined gradient map to ensure the accuracy and single-pixel width of the edge pixels. Finally, points with gradient values ​​greater than a preset threshold are identified as confirmed conveyor belt edge pixels.

[0049] Therefore, the controller 4 extracts the edge pixels of the conveyor belt from the images of the conveyor belt acquired by the four camera devices 31 based on the Canny edge detection algorithm.

[0050] Combination Figure 3 Furthermore, the controller 4 performs collection, packing, and array stacking processing on the edge pixels of the conveyor belt, calculates the correlation coefficient of the fitted line of the conveyor belt edge, and then calculates the slope and intercept of the fitted line of the conveyor belt edge through regression fitting processing to generate the fitted line of the conveyor belt edge.

[0051] As an example, controller 4 first collects all the edge pixels of the transport points into an array. Each pixel is a coordinate point with the top left corner of the pixel image as the origin, the horizontal axis as the x-axis, and the vertical axis as the y-axis. By collecting the edge pixels of the transport points into an array, a point set containing N point coordinates is obtained, such as two independent x-coordinate arrays and y-coordinate arrays, thereby converting the pixel positions into data points that can be processed mathematically. Next, controller 4 packs the point set into tuples based on the ZIP function, pairs the x and y values ​​with the same index, and creates an iterable object to obtain (x, y) tuples. Each tuple represents the complete coordinates of a pixel.

[0052] Furthermore, controller 4 uses the vstack function to vertically stack and transpose the x-coordinate array with an array of all 1s, constructing a design matrix A of shape [n,2]. This matrix creates the coefficient matrix required for the equation of the linear model y=ax+b, calculating the correlation coefficient of the conveyor belt edge fitting line. The first column corresponds to the independent variable x, and the constant term 1 in the second column corresponds to the intercept. Subsequently, the design matrix A and the y-coordinate array are passed to the lstsq function for solving. The lstsq function calculates the optimal solution that best represents the overall trend of all data points by minimizing the sum of squared errors. Then, the first and second elements of the solution are directly extracted from the result vector returned by the lstsq function, which are the slope a and intercept b of the fitted line, thus obtaining the linear equation that determines the conveyor belt edge fitting line. Finally, by substituting the preset x values ​​into the linear equation y=ax+b, all corresponding y values ​​are calculated to generate the conveyor belt edge fitting line.

[0053] Therefore, the controller 4 generates a conveyor belt edge fitting line based on the conveyor belt image acquired by the data acquisition component 3. Compared with the prior art, which detects the conveyor belt offset by applying pressure to the pressure sensor through the contact of the conveyor belt, this correction system generates a conveyor belt edge fitting line based on the conveyor belt image acquired by the data acquisition component 3. It can detect the conveyor belt offset in real time without direct contact with the conveyor belt, which can effectively improve the detection effect and correction accuracy.

[0054] Meanwhile, the edge fitting line of the conveyor belt can reflect the offset state of the conveyor belt throughout its entire journey. Only one set of correction system needs to be set on the conveyor to achieve accurate monitoring of the overall running trajectory of the conveyor belt, thereby improving detection accuracy and reducing correction costs.

[0055] Furthermore, the controller 4 calculates and compares the fit line of the conveyor belt edge with the preset conveyor belt baseline (fit line of the normal edge of the conveyor belt) to generate a correction signal for controlling the rotation of the correction roller 2.

[0056] Combination Figure 4 Specifically, the controller 4 calculates the shortest distance between the fitted line of the conveyor belt edge and the baseline of the conveyor belt, i.e. the amount of conveyor belt deviation, and judges the shortest distance and the distance threshold. If the shortest distance is greater than the distance threshold, it is judged that the conveyor belt has deviated. At the same time, the offset direction is judged by comparing the fitted line of the conveyor belt edge and the baseline of the conveyor belt, so as to generate a correction signal and transmit it to the drive mechanism 5, so that the drive mechanism 5 drives the push rod 51 to move, thereby driving the correction roller 2 to rotate in the direction of adjustment.

[0057] As an example, the controller 4 directly subtracts the x-axis pixel points of the conveyor belt edge fitting line from the conveyor belt baseline to obtain the deviation amount and direction of the conveyor belt edge points. If the shortest distance is greater than the distance threshold, it is determined that the conveyor belt has deviated.

[0058] At the same time, when the correction roller 2 rotates in the direction of adjustment, the amount of belt deviation and the fitting line of the conveyor belt edge will change. The data acquisition component 3 will collect the conveyor belt image in real time and transmit it to the controller 4, so that the controller 4 can update and calculate the fitting line of the conveyor belt edge in real time based on the latest conveyor belt image, and recalculate and judge the shortest distance to generate a correction signal, so that the drive mechanism 5 drives the correction roller 2 to rotate in the direction of adjustment.

[0059] In this way, the controller 4, data acquisition component 3, drive mechanism 5 and correction roller 2 work together to repeat the above-mentioned adjustment process, dynamically updating the conveyor belt image and the conveyor belt edge fitting line until the controller 4 determines that the shortest distance is not greater than the distance threshold. Then it is determined that the conveyor belt has not deviated, and the drive to rotate the correction roller 2 is stopped, thus completing the correction of the conveyor belt.

[0060] Therefore, by dynamically adjusting the guide roller 2, the conveyor belt can be dynamically adjusted, and multiple fine adjustments can be made to improve the accuracy of the guide belt and ensure the effect and reliability of the guide belt.

[0061] This constitutes the belt conveyor correction system provided by the present invention.

[0062] This invention also provides a belt conveyor correction method. This correction method acquires images of the conveyor belt in real time, generates a conveyor belt edge fitting line based on the conveyor belt image, calculates and compares the conveyor belt edge fitting line with the conveyor belt baseline, generates a correction signal, controls the rotation of the correction roller in real time to adjust the conveyor belt, and continuously acquires images of the conveyor belt in real time, dynamically updates the conveyor belt edge fitting line and the correction signal, and dynamically adjusts the conveyor belt.

[0063] The belt conveyor correction system and method provided by this invention can detect the offset state of the conveyor belt in real time without contact. Furthermore, the fitting line of the conveyor belt edge can reflect the offset state of the conveyor belt throughout its entire length. Only one correction system needs to be set up on the conveyor to achieve accurate monitoring of the overall running trajectory of the conveyor belt, thereby improving detection accuracy and reducing correction costs. At the same time, the controller 4 can cooperate with the drive mechanism 5 to adjust the rotation of the correction roller in real time and dynamically according to the fitting line of the conveyor belt edge, thereby achieving efficient and accurate active correction. This correction system not only significantly reduces the hardware cost of multi-point deployment, but also significantly improves the timeliness, effectiveness, and operational reliability of correction due to its single-point full-process monitoring and rapid response characteristics.
