Description

Technical Field

[0001] The present invention relates to the technical field of conveyor deviation correction, and more specifically, to a multiple intelligent deviation correction system based on deviation sensors and a control method thereof. Background Art

[0002] As an important material conveying equipment, belt conveyor has a wide range of applications in industrial and mining enterprises and logistics industries. The working principle of belt conveyor is based on friction drive, and the material is conveyed through the continuous movement of the conveyor belt. The material is placed on the conveyor belt and transported from the feeding point to the unloading point. This equipment can not only transport horizontally, but also transport at an angle within a certain angle; in addition, multiple units can be combined or used in conjunction with other conveying equipment to meet different job layout requirements.

[0003] However, during the operation of the belt conveyor, the deviation of the conveyor belt is a common fault phenomenon. There are many reasons for its occurrence, but they will cause problems in the transportation of materials and affect production efficiency and safety. As a result, many belt conveyor deviation correction devices have appeared on the market. Common belt conveyor deviation correction devices mainly detect the position of the conveyor belt in real time through deviation sensors. When the conveyor belt deviates, the sensor will send a signal. The control system receives and processes these signals, and then drives the actuator to apply a certain torque to the conveyor belt to return it to the correct position.

[0004] Although there are many web-correcting devices on the market, as mentioned above, they mainly work based on the principle of single-body web-correction, which relies on the web-correction sensor to monitor the deviation of the conveyor belt in real time and take corresponding corrective measures after the deviation is detected. However, this single-body web-correction method has some limitations, such as insufficient web-correction capability, lack of intelligence, and especially poor web-correction effect.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a multiple intelligent deviation correction system based on deviation sensors and a control method thereof. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the present invention is to provide a multiple intelligent deviation correction system based on deviation sensors and a control method thereof.

[0007] To achieve the above object, the present invention provides the following technical solution: a multiple intelligent deviation correction system based on deviation sensors, comprising:

[0008] The deviation correction mechanism includes a plurality of deviation correction devices and a plurality of deviation sensors. A deviation sensor is installed at a corresponding position on each deviation correction device, and each deviation correction device is arranged at an equal distance on the conveyor belt.

[0009] Preferably, when the deviation sensor on the Xth deviation-correcting device detects that there is a problem with the transport status of the conveyor belt, the deviation-correcting mechanism will drive the X-1th deviation-correcting device, the X+1th deviation-correcting device and the Xth deviation-correcting device to perform deviation-correcting operations on the conveyor belt at the same time.

[0010] Preferably, when the deviation sensor on the Xth deviation-correcting device detects that there is a problem with the transport status of the conveyor belt, the deviation-correcting mechanism will drive the X+1th deviation-correcting device, the X+2th deviation-correcting device and the Xth deviation-correcting device to perform deviation-correcting operations on the conveyor belt at the same time.

[0011] Preferably, the multiple intelligent deviation correction system also includes a real-time monitoring module, which obtains the thrust of the deviation correction equipment, uploads it to the cloud, and pushes it to a mobile terminal or PC. The belt deviation correction system can be remotely monitored on the PC or mobile terminal.

[0012] A multiple intelligent deviation correction control method based on deviation sensors, the multiple intelligent deviation correction control method based on deviation sensors comprises the following steps:

[0013] A: The interval distance of the deviation correction mechanism is set according to the actual production needs, and the running state of the conveyor belt in the belt conveyor is detected by the plurality of deviation sensors, including but not limited to sensing the distance between the center line of the conveyor belt and the sensor, and the inclination angle of the conveyor belt;

[0014] B: When the data measured by the current deviation sensor changes, the system will use the data measured by the deviation sensor to mobilize the current deviation correction equipment to correct the conveyor belt;

[0015] C: If the step B fails to complete the conveyor belt deviation correction operation within the specified time, the system will drive a group of deviation correction devices as an auxiliary to participate in the conveyor belt deviation correction work. If the deviation correction fails, the next group of deviation correction devices will be driven to correct the conveyor belt until the deviation correction is successful.

[0016] Preferably, the deviation sensor in step A is set with an offset threshold. If the offset data returned to the system does not exceed this threshold, it is considered normal and no processing is performed. If it exceeds the threshold, analysis is performed based on the returned data to obtain the angle and distance of the deviation.

[0017] Preferably, the preferred deviation-correcting devices participating in the deviation correction in step C are preferably the preceding deviation-correcting devices and the succeeding deviation-correcting devices whose deviation sensors detect that the conveyor belt has deviated.

[0018] Preferably, after the deviation correction fails in step C, one deviation correction device will be moved forward and backward to participate in the deviation correction operation of the conveyor belt.

[0019] Preferably, if the correction operation fails to be successfully performed in step C, all subsequent devices participating in the correction will receive from the system the final offset data of the deviation sensors in all the correction devices in the previous round of correction process.

[0020] Preferably, in step C, the system will determine that the deviation correction operation is successfully completed only when the data detected by the deviation sensors on all the deviation correction devices involved in the deviation correction indicate that the conveyor belt status is completely within the normal range.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the running state of the conveyor belt in the belt conveyor is detected by a plurality of deviation sensors. When the data measured by the current deviation sensor changes, the system will mobilize the current deviation correction device to correct the conveyor belt according to the data measured by the deviation sensor. If the deviation correction operation of the conveyor belt is not completed within the specified time, the system will drive a group of deviation correction devices as an auxiliary to participate in the deviation correction work of the conveyor belt. If the deviation correction fails, the next group of deviation correction devices will be driven to correct the conveyor belt until the deviation correction is successful. The deviation correction capability is improved by the joint work of multiple deviation correction devices.

[0023] 2. In the present invention, the thrust of the deviation correction device is obtained through the real-time monitoring module, uploaded to the cloud through the 5G network, and pushed to the mobile terminal and PC terminal. On the PC and mobile terminals, the belt deviation correction system can be remotely monitored, operated, maintained and processed to extend the service life of the belt conveyor. DETAILED DESCRIPTION

[0024] Example 1

[0025] A multiple intelligent deviation correction system based on deviation sensors includes a deviation correction mechanism, wherein the deviation correction mechanism includes a plurality of deviation correction devices and a plurality of deviation sensors, a deviation sensor is installed at a corresponding position on each deviation correction device, and each deviation correction device is arranged at an equal distance on the conveyor belt;

[0026] When the deviation sensor on the Xth deviation-correcting device detects that there is a problem with the transport state of the conveyor belt, the deviation-correcting mechanism will drive the X-1th deviation-correcting device, the X+1th deviation-correcting device and the Xth deviation-correcting device to perform deviation-correcting operations on the conveyor belt at the same time;

[0027] Alternatively, when the deviation sensor on the Xth deviation-correcting device detects that there is a problem with the transport state of the conveyor belt, the deviation-correcting mechanism will drive the X+1th deviation-correcting device, the X+2th deviation-correcting device, and the Xth deviation-correcting device to perform deviation-correcting operations on the conveyor belt at the same time;

[0028] It should be noted that a multiple intelligent deviation correction system also includes a real-time monitoring module. The real-time monitoring module will obtain the thrust size of the deviation correction equipment, upload it to the cloud, and push it to the mobile terminal or PC. On the PC or mobile terminal, the belt deviation correction system can be remotely monitored.

[0029] Example 2

[0030] The multiple intelligent deviation correction system based on deviation sensors in Example 1 is used to perform a multiple intelligent deviation correction control method based on deviation sensors, comprising the following steps:

[0031] A: The interval distance of the deviation correction mechanism is set according to the actual production needs, and the running state of the conveyor belt in the belt conveyor is detected by the plurality of deviation sensors, including but not limited to sensing the distance between the center line of the conveyor belt and the sensor, and the inclination angle of the conveyor belt;

[0032] B: When the data measured by the current deviation sensor changes, the system will use the data measured by the deviation sensor to mobilize the current deviation correction equipment to correct the conveyor belt;

[0033] C: If the above step B still fails to complete the conveyor belt deviation correction operation within the specified time, the system will drive a group of deviation correction equipment as an auxiliary to participate in the conveyor belt deviation correction work. If the deviation correction fails, the next group of deviation correction equipment will be driven to correct the conveyor belt until the deviation correction is successful;

[0034] Among them, the deviation sensor in step A is set with an offset threshold. If the offset data returned to the system does not exceed this threshold, it is considered normal and no processing is performed. If it exceeds the threshold, analysis is performed based on the returned data to obtain the angle and distance of the deviation. The preferred deviation correction device participating in step C gives priority to the previous deviation correction device and the next deviation correction device whose deviation sensor detects that the conveyor belt has deviated. When the deviation correction in step C fails, one deviation correction device will be mobilized forward and backward to participate in the deviation correction operation of the conveyor belt. If the deviation correction operation in step C is not successfully performed, all subsequent devices participating in the deviation correction will receive from the system the final offset data of the deviation sensors in all deviation correction devices in the previous round of deviation correction. Only when the data detected by the deviation sensors on all deviation correction devices participating in the deviation correction indicate that the conveyor belt status is completely within the normal range, the system will determine that the deviation correction operation is successfully completed.

[0035] Example 3

[0036] There are 100 deviation correction mechanisms. When the deviation sensor in the 50th deviation correction mechanism detects a belt deviation problem, the 50th deviation correction device automatically performs deviation correction. If the deviation correction fails, the system will select a pair of deviation correction devices located in front and behind the 50th deviation correction device through the data measured by the deviation sensor to participate in the deviation correction work of the conveyor belt. In this embodiment, the system selects the 49th and 51st deviation correction devices to participate in the correction for the first time.

[0037] The system wakes up the two correcting devices, and then sends the current deviation information and the number of the correcting device where the deviation occurred to the two correcting devices that were awakened. After receiving this information, each correcting device analyzes and determines the angle, rotation direction, and movement range of the push rod that it should correct, and cooperates with the 50th correcting device that initially detected the belt deviation to correct the deviation again within the specified time. For example, if the deviation to the right is the deviation in the positive direction, the device involved in the correction should adjust the belt in the negative direction, and vice versa; by calculating the difference between its own offset (without considering the threshold problem in the calculation) and the offset of the device closer to the center of the deviation relative to itself, plus parameters such as the device spacing and the roller radius, the angle to be adjusted and the movement range of the push rod are calculated. According to the calculated data, the correcting device operates; the rotary encoder in the high-precision electric cylinder can measure the rotation angle of the roller to ensure real-time feedback and dynamic adjustment of the correction angle during the adjustment process; the push rod contains a thrust sensor, which can monitor the thrust size in real time. The thrust size obtained by real-time monitoring will be uploaded to the cloud through the 5G network and pushed to the mobile terminal and PC terminal. On the PC and mobile terminals, the belt deviation correction system can be remotely monitored, operated, maintained and processed to extend the service life of the belt conveyor.

[0038] Regardless of success or failure, the correction results must be sent to the system. If successful, the system stops the correction; if failed, the nearest correction device is taken to the left and right, in this example, the 48th and 52nd, and the above steps are repeated for correction. At this time, the devices involved in the correction are 48, 49, 50, 51, and 52. All correction devices that participate in the correction will receive from the system the final offset detected by the deviation sensors on all correction devices that participated in the previous correction. The correction will be judged as successful only when the deviation sensors on all correction devices involved in the correction are in normal operation.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
