Description

Technical Field

[0001] The present application relates to the technical field of deviation adjustment of belt conveyors, and in particular to a deviation adjustment mechanism, a test system for the deviation adjustment mechanism, and a test method. Background Art

[0002] In recent years, due to the growing emphasis on environmental protection both domestically and internationally, the application of circular tube belt conveyors ("tube conveyors") has become increasingly widespread. The location and structure of a tube conveyor, including its head, tail, material receiving point, discharge point, and tensioning device, are essentially the same as those of a conventional belt conveyor. However, the central conveying section between the loading point and the discharge point is formed into a circular tube, known as the forming section. If the overlapping edge of the belt in the forming section deviates during operation, it can cause abnormal wear on the conveyor belt and forming rollers, and may even cause material spillage and belt flipping, seriously impacting the normal operation of the equipment.

[0003] Therefore, in order to ensure normal operation, it is necessary to set up an adjustment mechanism to adjust the tape, which specifically includes a detection part and an adjustment part. Among them, the detection part is used to detect the deviation of the tape, and the adjustment part will adjust the tape to ensure normal operation of the equipment.

[0004] However, during the adjustment process of the adjustment mechanism in the prior art, the accuracy of the detection results of the detection part cannot be guaranteed, and the adjustment operation of the adjustment part is cumbersome, and it is easy to have misadjustments, wrong adjustments, missed adjustments, etc., and the reliability is low. How to improve the reliability of the adjustment mechanism and simplify the adjustment operation is a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0005] The purpose of this application is to provide a deviation adjustment mechanism, a test system and a test method for the deviation adjustment mechanism, which can improve the accuracy and reliability of the deviation adjustment mechanism in adjusting the belt of a belt conveyor and simplify the adjustment operation.

[0006] In order to solve the above technical problems, the present application provides a deviation adjustment mechanism for adjusting the belt of a belt conveyor, the deviation adjustment mechanism including a controller, a detection unit and a deviation adjustment unit; the detection unit includes a ring and a detection element provided on the ring, the ring can drive the detection element to rotate relative to the belt, the detection element is used to detect the position data of the belt, and the deviation adjustment unit is used to adjust the belt; the controller stores a control program, the controller is respectively connected to the detection unit and the deviation adjustment unit signal, the controller can obtain the position data, and can perform parameter correction on the control program according to multiple sets of position data under different preset deviation angles, and can also calculate the current deviation angle of the belt according to the current position data and the control program, and when the deviation angle reaches a preset threshold, control the deviation adjustment unit to adjust the belt until the deviation angle is less than the preset threshold.

[0007] Since the circular ring of the detection part can rotate relative to the tape, the circular ring can be used to drive the detection element to rotate relative to the tape to simulate the situation where the tape deviates during actual application.

[0008] This deviation adjustment mechanism simulates belt deviation by rotating the ring to achieve relative rotation between the detection unit and the belt, even without the conveyor running. This simplifies the process and reduces test energy consumption and costs. Furthermore, rotating the ring during testing can prevent false detection, inaccurate detection, or failure to perform deviation adjustments during the conveyor's startup, improving safety and stability.

[0009] In addition, the control program is parameter-corrected through multiple position data at preset deviation angles, and then the deviation angle of the tape is calculated based on the current position data and the control program. This ensures the accuracy of subsequent deviation angle calculations and is suitable for tapes of different specifications, with a wide range of applications and good flexibility.

[0010] In addition, the adjustment operation of the adjustment part is controlled by a controller, and the position data is monitored in real time by the detection part to determine whether the adjustment operation is needed and whether the adjustment operation is completed. This can simplify manual operation, and the tape can be adjusted to the target state in time, and the accuracy and reliability of the adjustment results can be guaranteed.

[0012] Optionally, the detection part further includes a lifting lug, which is used to connect to the frame of the belt conveyor. The outer edge of the ring is provided with a slideway along the circumference. The lifting lug can slide along the slideway and can be fixed to the ring by a fastener.

[0015] The present application also provides a test system for an adjustment mechanism, including a pipe conveyor and the adjustment mechanism as described above, wherein the pipe conveyor includes a frame and a tape, the detection part and the adjustment part of the adjustment mechanism are both arranged on the frame, and the circular ring of the detection part can rotate relative to the frame.

[0016] Optionally, it also includes a deflection-inducing part, which includes a bracket, a pushing member and a deflection-inducing roller. The bracket is fixed to the frame, and the pushing member can act on the deflection-inducing roller to make the deflection-inducing roller approach or move away from the tape. The deflection-inducing roller abuts against the tape to deflect the tape.

[0017] Optionally, there are two deflection-inducing portions, which are spaced apart along the axial direction of the adhesive tape and can respectively guide the adhesive tape to deviate in different directions.

[0018] This application also provides a test method for an adjustment mechanism, comprising the following steps:

[0049] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] An embodiment of the present application provides a deviation adjustment mechanism, a test system for the deviation adjustment mechanism, and a test method for the deviation adjustment mechanism, wherein the deviation adjustment mechanism is used to adjust the tape 12 of the pipe-forming section of the pipe conveyor 1 to prevent the normal operation of the equipment from being affected by the deviation of the tape 12. The test system and test method for the deviation adjustment mechanism are respectively used to test the deviation adjustment mechanism to ensure the reliability of the deviation adjustment mechanism.

[0051] The deviation adjustment mechanism includes a controller, a detection unit 2 and a deviation adjustment unit 3, wherein the detection unit 2 is used to detect the position data of the tape 12, and the detection unit 2 includes a ring 21 and a detection element arranged on the ring 21, wherein the ring 21 can rotate relative to the tape 12 to simulate the working condition of the tape 12 running off, the detection element is used to detect the position data of the tape 12, and the deviation adjustment unit 3 is used to perform deviation adjustment operations on the tape 12.

[0052] Specifically, the controller stores a control program, and the controller is respectively connected to the detection part 2 and the deviation adjustment part 3 by signal, and can obtain position data. The controller can correct the parameters of the control program according to multiple sets of position data under different preset deviation angles, and can also calculate the current deviation angle of the tape 12 according to the current position data and the control program, and when the deviation angle reaches a preset threshold, control the deviation adjustment part 3 to perform an adjustment operation on the tape 12 until the deviation angle is less than the preset threshold.

[0053] Since the ring 21 of the detection part 2 can rotate relative to the tape 12, the ring 21 can drive the detection element to rotate relative to the tape 12 to simulate the situation where the tape 12 deviates during actual application.

[0054] Specifically, when the ring 21 rotates relative to the tape 12 to -120°, -60°, 60°, 120° and 180° respectively, the position data of the tape 12 detected by the detection element is input into the controller to correct the parameters of the control program. Then, when the ring 21 is rotated relative to the tape 12 to any angle, the detection element detects the position data of the tape 12 in real time. The controller can calculate the current deviation angle of the tape 12 based on the current position data and the control program. If the deviation angle reaches the preset threshold, it means that the tape 12 needs to be adjusted. The controller sends a control instruction to the adjustment unit 3, and the adjustment unit 3 adjusts the tape 12 according to the control instruction. At the same time, the detection unit 2 also monitors the position data of the tape 12 in real time. When the controller calculates that the current deviation angle is less than the preset threshold, the adjustment operation of the adjustment unit 3 is stopped, and the adjustment is completed.

[0055] Of course, in this embodiment, there is no specific limitation on the number and angle values ​​of the preset deviation angles, and they can be set according to actual conditions.

[0056] The deviation adjustment mechanism provided in this embodiment can simulate the deviation of the tape 12 by rotating the ring 21 to achieve relative rotation between the detection unit 2 and the tape 12, even without the tape conveyor 1 being in operation. This simplifies the operating process and reduces testing energy consumption and costs. Furthermore, rotating the ring 21 during testing can prevent false detection, inaccurate detection, or failure to perform deviation adjustment during the startup of the tape conveyor 1, thereby improving safety and stability.

[0057] In addition, the control program is parameter-corrected through multiple position data at preset deviation angles, and then on this basis, the deviation angle of the tape 12 is calculated through the current position data and the control program, which can ensure the accuracy of subsequent deviation angle calculations and is suitable for tapes 12 of different specifications, with a wide range of applications and good flexibility.

[0058] In addition, the adjustment operation of the adjustment part 3 is controlled by the controller, and the position data is monitored in real time by the detection part 2 to determine whether the adjustment operation is needed and whether the adjustment operation is completed. This can simplify manual operation, and the tape 12 can be adjusted to the target state in time, and the accuracy and reliability of the adjustment result can be guaranteed.

[0059] like Figure 2 As shown, the detection unit 2 also includes a collection unit 25 and six distance sensors 22 evenly spaced along the circumference of the ring 21. Each distance sensor 22 is used to monitor the distance between itself and the tape 12, which forms the aforementioned position data. Because the tape 12 has overlapping edges at the tubular section, the distance data detected by the distance sensors 22 varies depending on the position of the tape 12. The collection unit 25 is signal-connected to each distance sensor 22 and the controller, and is used to collect the distance data detected by each distance sensor 22 and then transmit the distance data to the controller.

[0060] Specifically, how the acquisition unit 25 collects the distance data detected by each distance sensor 22 through signal connection and then sends the distance data to the controller is already a well-known existing technology for those skilled in the art and will not be described here in order to save space.

[0061] Of course, in this embodiment, the specific structure of the detection unit 2 is not limited. For example, an angle position sensor may be used to directly detect angle data, or a camera may be used to monitor the position data of the tape 12. Using the distance sensor 22 (e.g., an ultrasonic distance sensor) to detect the distance data of the tape 12 as position data ensures the accuracy of the detection results, thereby ensuring the reliability of the deviation adjustment mechanism.

[0062] Of course, there is no limit to the number of distance sensors 22 , and the number can be four, five, eight, etc.

[0063] like Figure 2 As shown, the detection unit 2 further includes a lifting lug 23, which is rotatably connected to the ring 21. The detection unit 2 can be connected to the frame 11 via the lifting lug 23. With this arrangement, the ring 21 can rotate relative to the frame 11, and thus relative to the adhesive tape 12. Specifically, during use, the ring 21 is fixed to the frame 11 and does not rotate, while the adhesive tape 12 moves on the frame 11. When the adhesive tape 12 deviates, it can rotate relative to the ring 21. By configuring the ring 21 to be rotatable relative to the frame 11 via the lifting lug 23, the conversion and detection unit can be rotated relative to the adhesive tape 12 when the belt conveyor 1 is in the stopped state. This arrangement has a relatively simple structure.

[0064] like Figure 2 As shown, the outer edge of the ring 21 is provided with a slideway 211 along the circumferential direction, and the lug 23 can slide along the slideway 211 to enable the ring 21 to rotate relative to the frame 11, and the lug 23 and the ring 21 can also be fixed by fasteners. Specifically, the lug 23 is provided with a screw 24, and the edge of the ring 21 is provided with an abutment portion. When the screw 24 is tightened, it can abut the abutment portion to limit the relative rotation of the lug 23 and the ring 21, so that the two are relatively fixed. When the ring 21 needs to be rotated, the screw 24 can be removed or loosened. When the ring 21 does not need to be rotated, the screw 24 can be tightened. It has good flexibility and is easy to operate.

[0065] The circular ring 21 comprises a first ring body and a second ring body arranged circumferentially, which are detachably connected. During installation, the first and second ring bodies can be attached to either side of the tape 12 from the outer periphery and secured coaxially with the tape 12. This facilitates installation of the detection unit 2. Furthermore, the detection unit 2 can be used universally to detect deviation of the belt conveyor 1 for various applications, improving applicability while reducing equipment costs.

[0066] like Figure 3 As shown, the deflection adjustment mechanism includes a driving member 31, a deflection adjustment roller 32, a support plate 33, and a guide rod 34. The support plate 33 has a mating hole 331, through which the guide rod 34 passes. One end of the guide rod 34 is pivotally connected to the driving member 31, while the other end of the guide rod 34 is fixed to the deflection adjustment roller 32. The driving member 31 is connected to a controller signal. The controller can send a control signal to the driving member 31. In response to the control signal, the driving member 31 pushes or pulls the guide rod 34 away from one end of the deflection adjustment roller 32, driving the guide rod 34 to abut against the walls of the mating hole 331, causing the deflection adjustment roller 32 to swing.

[0067] When the guide rod 34 is not in contact with the wall of the matching hole 331, the deviation adjustment roller 32 can roll in contact with the surface of the tape 12, and the deviation adjustment roller 32 can provide a guiding function for the tape 12. When the guide rod 34 is in contact with the wall of the matching hole 331, the deviation adjustment roller 32 swings to a preset angle and acts on the tape 12, which can deflect the tape 12 to the side opposite to the deviation direction, thereby achieving return to the center.

[0068] Specifically, in this embodiment, there is no limitation on the driving member 31 , and it may be, for example, a piston rod of a pneumatic cylinder, a piston rod of a hydraulic cylinder, or a motor screw assembly.

[0069] like Figure 1As shown, the test system for the deviation adjustment mechanism provided in the embodiment of the present application includes a pipe conveyor 1 and the deviation adjustment mechanism described above, wherein the pipe conveyor 1 includes a frame 11, an adhesive belt 12, and a forming roller assembly 13, wherein the forming roller assembly 13 is disposed on the frame 11 and is used to provide guidance for the movement of the adhesive belt 12. The detection unit 2 and the deviation adjustment unit 3 of the deviation adjustment mechanism are both disposed on the frame 11, and the circular ring 21 of the detection unit 2 is coaxially arranged with the adhesive belt 12 and can rotate relative to the frame 11. The pipe conveyor 1 used in this embodiment can be the pipe forming section of equipment used in actual production, or can be a test bench simulating actual production equipment.

[0070] By testing the deviation adjustment mechanism provided by the test system of the embodiment, the accuracy of the deviation adjustment mechanism in detecting the deviation of the tape 12 and the reliability of the deviation adjustment can be ensured, thereby ensuring that the belt conveyor 1 can operate stably.

[0071] The technical effect of the test system of the deviation adjustment mechanism is similar to the technical effect of the above-mentioned deviation adjustment mechanism. To save space, it will not be repeated here.

[0072] like Figure 1 As shown, the test system for the deviation adjustment mechanism also includes a deviation-inducing unit 4, which includes a bracket 41, a pusher, and a deviation-inducing roller 42. The bracket 41 is detachably connected to the frame 11 and can be mounted at any position on the frame 11. The pusher can push the deviation-inducing roller 42, causing it to move relative to the bracket 41 toward or away from the tape 12. The deviation-inducing roller 42 can act on the surface of the tape 12, causing it to deviate. The axis of the deviation-inducing roller 42 is at a predetermined angle to the axis of the tape 12. When the deviation-inducing roller 42 presses against the surface of the tape 12, the tape 12 continues to move forward, causing it to twist to varying degrees, thereby causing it to deviate.

[0073] During the test, the deviation of the belt 12 is induced by the deviation-inducing roller 42 to simulate the deviation condition of the belt 12 under actual application conditions. The applicability of the integrated deviation detection and adjustment system can be verified from all angles. The experimental results are more comprehensive and effective, and can also effectively improve the test efficiency and ensure the accuracy of the experimental results.

[0074] The inducing part induces the tape 12 to deviate, the detecting part 2 detects the deviation of the tape 12, and the deviation adjusting part 3 can correct the deviation of the tape 12. The test system of the deviation adjusting mechanism is composed of an integrated test system consisting of the inducing part, the detecting part 2 and the deviation adjusting part 3. Combined with the test method of the deviation adjusting mechanism, the feasibility of application under simulated actual working conditions can be fully explored.

[0075] There is no restriction on the specific structure of the pusher. Figure 4As shown, the pushing member is a push wheel 43. The bracket 41 is provided with a mounting plate with a screw hole. The push wheel 43 is connected to the deflection-inducing roller 42 via a screw. The screw engages the screw hole. When the push wheel 43 rotates, the screw thread engages and moves along the axial direction of the screw hole, thereby driving the deflection-inducing roller 42 toward or away from the tape 12. Applying different external forces to the push wheel 43 can change the degree of pressure applied by the deflection-inducing roller 42 on the tape 12, thereby simulating different deviation states of the tape 12. Using the push wheel 43 as the pushing member ensures stable adjustment of the movement of the deflection-inducing roller 42.

[0076] Specifically, there are two deflection inducing parts 4, which are arranged at intervals along the axial direction of the tape 12 and are respectively arranged on the frame 11. The two deflection inducing parts 4 can respectively guide the tape 12 to deviate in two directions, that is, one of the deflection inducing parts 4 can guide the tape 12 to deviate clockwise, and the other deflection inducing part 4 can guide the tape 12 to deviate counterclockwise. In this way, the authenticity of the simulated tape 12 during actual operation can be further improved.

[0077] In detail, during the normal test process, only one deflection inducing part 4 can interact with the tape 12 to guide the tape 12 to deviate, and then the controller will control the deflection adjusting part 3 to adjust the tape 12. If there is a problem with the control program or the component installation or even other faults, resulting in the deflection adjusting part 3 being unable to adjust the tape 12 to return it to its original position, the push wheel 43 can be manually operated to enable the other deflection inducing part 4 to guide the tape 12 to deviate in the opposite direction, thereby returning the tape 12 to its original position, avoiding the impact on the equipment due to the excessive deviation angle of the tape 12, and ensuring the reliability of the test process.

[0078] That is, one deflection inducing portion 4 is used to guide the adhesive tape 12 to deviate, and the other deflection inducing portion 4 is used to adjust the adhesive tape 12 in an emergency.

[0079] like Figure 5 As shown, the test method of the adjustment mechanism provided in the embodiment of the present application includes the following steps:

[0080] S1: Rotate the ring 21 relative to the tape 12 to a plurality of different preset deviation angles, and monitor the position data of the tape 12 in real time through the detection unit 2;

[0081] S2: Modify the parameters of the control program according to the position data at each preset deviation angle.

[0082] The control program is parameter-corrected by using position data at multiple preset deviation angles, and then the deviation angle of the tape 12 is calculated based on the current position data and the control program. This ensures the accuracy of subsequent deviation angle calculations and is applicable to tapes 12 of different specifications, with a wide range of applications and good flexibility.

[0083] S3: rotating the ring 21 to any angle relative to the tape 12, and monitoring the current position data of the tape 12 in real time through the detection unit 2;

[0084] S4: Calculate the deviation angle of the tape 12 based on the current position data and the control program, and determine whether the deviation angle reaches a preset threshold. If so, proceed to step S5;

[0085] S5: The tape 12 is adjusted by the adjustment unit 3;

[0086] S6: Determine whether the deviation angle can be reduced below a preset threshold. If not, proceed to step S7;

[0087] S7: Adjust the control program and check the installation status, and repeat steps S1-S6.

[0088] The installation condition refers to the installation condition of the various components of the deviation adjustment mechanism, such as the detection part 2, the deviation adjustment part 3, etc.

[0089] The deviation adjustment operation of the deviation adjustment part 3 is controlled by the controller, and the position data monitored in real time by the detection part 2 is used to determine whether the deviation adjustment operation is needed and whether the deviation adjustment operation is completed. This can simplify manual operation, and the tape 12 can be adjusted to the target state in time, and the accuracy and reliability of the deviation adjustment result can be guaranteed.

[0090] Without the pipe conveyor 1 being in operation, the ring 21 is rotated to achieve relative rotation between the detection unit 2 and the tape 12, simulating a deviation condition of the tape 12. This simplifies the operating process and reduces test energy consumption and costs. Furthermore, rotating the ring 21 during testing can prevent false detection, inaccurate detection, or failure to perform deviation adjustments during the start-up of the pipe conveyor 1, thereby improving safety and stability.

[0091] Further, such as Figure 6 As shown, in step S6, it is determined whether the deviation angle can be reduced to below a preset threshold. If so, step S8 is performed;

[0092] S8: The ring 21 is fixed relative to the frame 11, the tape 12 is moved along the frame 11, and the tape 12 is guided to deviate so that the deviation angle is greater than a preset threshold;

[0093] S9: determining whether the deviation adjusting unit adjusts the deviation of the belt and reduces the deviation angle to below the preset threshold, and if not, proceeding to step S10:

[0094] S10: adjusting the influencing factors and repeating steps S8-S9.

[0095] Steps S3-S7 correspond to a static test, in which the pipe belt machine 1 remains in a stopped state, and the pipe belt machine 1 is simulated to have a deviation by rotating the ring 21. When the deviation angle is reduced to below the preset threshold in step S6, the static test is completed, indicating that the deviation adjusting mechanism has no problem and can ensure accurate detection and adjustment of the deviation of the belt 12 of the pipe belt machine 1. Steps S8-S10 correspond to a dynamic test, which is specifically that the pipe belt machine 1 is started, the position of the ring 21 is fixed, and the deviation adjusting mechanism is tested by inducing the actual deviation of the belt 12 by the deviation inducing unit 4 during the actual operation of the pipe belt machine 1.

[0096] That is, after ensuring that the control program and the installation, detection, and adjustment of the detection unit 2 and the deviation adjusting unit 3 have no problem through the static test, the ring 21 is fixed, the pipe belt machine 1 is started, and the dynamic test is performed. In this way, compared with directly performing the dynamic test, the probability of problems occurring during the dynamic test can be reduced, which is a protection for the pipe belt machine 1 and the detection unit 2 and the deviation adjusting unit 3, avoiding equipment damage, and also reducing energy consumption and improving economic efficiency.

[0097] The influencing factors in step S10 can specifically refer to factors during the dynamic test, such as the installation of the deviation inducing unit 4, the fixing of the ring 21 of the detection unit 2, and the operation of the pipe belt machine 1 itself, without specific limitation.

[0098] In step S9, it is determined whether the deviation adjusting unit adjusts the deviation of the belt and reduces the deviation angle to below the preset threshold, and if so, step S11 is performed: repeating steps S8-S9 a preset number of times, and in step S8, the belt 12 is guided to deviate in different directions.

[0099] That is, during the dynamic test, the belt 12 can be guided to deviate in different directions by the deviation inducing unit 4, and the dynamic test can be repeated a preset number of times (such as eight times, ten times, etc.). Through the repeated test of the preset number of times, the overall reliability of the deviation adjusting mechanism can be improved.

[0100] Further, in step S8, the deviation inducing unit 4 is installed to the rack 11. When the deviation inducing unit 4 has two, the two deviation inducing units 4 are installed to the rack 11 at intervals, so that the two deviation inducing units 4 can guide the belt 12 to deviate in two different directions.

[0101] Furthermore, one deflection inducing portion 4 can guide the adhesive tape 12 to deviate, and the other deflection inducing portion 4 can adjust the adhesive tape 12, such as Figure 6 As shown, in step S10, the influencing factors are adjusted and steps S8-S9 are repeated. At the same time, the tape 12 is guided by another deflection-inducing part 4 so that the tape 12 deflects in the opposite direction until the deviation angle is reduced to below the preset threshold, and then steps S8-S9 are repeated.

[0102] like Figure 6 As shown, before step S1, the following steps are also included:

[0103] S01: Install the detection unit 2 and the deviation adjustment unit 3 on the frame 11 of the pipe conveyor 1, wherein the pipe conveyor 1 includes the frame 11 and the adhesive tape 12;

[0104] S02: Initialize the deviation adjustment unit 3.

[0105] The deviation adjusting unit 3 is initialized so that the deviation adjusting roller 32 returns to its original position. At this time, the guide rod 34 does not abut against the side wall of the matching hole 331 , and the deviation adjusting roller 32 only provides a guiding function for the adhesive tape 12 .

[0106] Specifically, during the dynamic test process, the test data under various working conditions are collected and processed, the actual operation results of the system are analyzed, the device design and implementation control methods are optimized, and the reliability and stability of the system operation are improved.

[0107] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
