[0041] The present application provides a deviation rectifying device, a deviation rectifying system and a deviation rectifying method of a pipe belt machine. In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme of the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0042] First, the pipe belt machine 3 is introduced, referring to Figure 1 .

[0043] The pipe belt machine 3 includes an adhesive tape 301, a truss 302, a conveying roller 303 and a first fixing support 304. There are two adhesive tapes 301 in the figure, which are wound into a tubular shape, and the uppermost forms an overlapping area. A plurality of first fixing supports 304 are fixed on the truss 302 in sequence and at intervals, and the two adhesive tapes 301 pass through each first fixing support 304 in sequence. Each first fixing support 304 is connected with two sets of conveying rollers 303, and each set of conveying rollers 303 is used to convey the two adhesive tapes 301, and each set has a plurality of conveying rollers 303 arranged in sequence along the circumference of the adhesive tape 301. Each conveying roller 303 includes a conveying roller body 3031 and a conveying roller support (not shown in the figure), and the conveying roller support is fixed on the first fixing support 304, and the conveying roller body 3031 is rotatably connected to the conveying roller support, and the outer cylindrical surface of the conveying roller body 3031 is in contact with the outer cylindrical surface of the adhesive tape 301 to play a conveying role.

[0044] During the operation of the pipe belt machine, the adhesive tape 301 may deviate, that is, the overlapping area of the adhesive tape 301 deviates from the upper side to the two sides or even the lower side, causing problems such as abnormal wear and tear and material falling off.

[0045] Next, the deviation rectifying device 1 provided by the present application is introduced, referring to Figures 2-5 .

[0046] The deviation rectifying device 1 comprises a deviation rectifying support 101, a plurality of deviation rectifying rollers 104 arranged along the circumference of the rubber belt 301 in sequence, a deviation rectifying driving member 102 and a deviation rectifying transmission part 103.

[0047] After the deviation rectifying device 1 is installed on the pipe belt conveyor 3, the position of the deviation rectifying support 101 is fixed. During operation, the plurality of deviation rectifying rollers 104 simultaneously rectify the rubber belt 301, and a good rectification effect can be achieved. In the figure, the deviation rectifying device 1 has three deviation rectifying rollers 104, and in actual implementation, the number of deviation rectifying rollers 104 of the deviation rectifying device 1 can also be two or more than three.

[0048] Each deviation rectifying roller 104 comprises a deviation rectifying roller frame 1042 and a deviation rectifying roller body 1041. The deviation rectifying roller frame 1042 is rotatably connected to the deviation rectifying support 101, and the rotation axis of the deviation rectifying roller frame 1042 is substantially perpendicular to the outer circumferential surface of the rubber belt 301. The deviation rectifying roller body 1041 is rotatably connected to the deviation rectifying roller frame 1042, and the outer circumferential surface of the deviation rectifying roller body 1041 is in contact with the outer circumferential surface of the rubber belt 301. When the deviation rectifying roller frame 1042 rotates relative to the deviation rectifying support 101, the deviation rectifying roller body 1041 will rotate together with the deviation rectifying roller frame 1042, and at this time, the outer circumferential surface of the deviation rectifying roller body 1041 will frictionally drive the rubber belt 301 to deflect, so as to rectify the rubber belt 301.

[0049] The deviation rectifying driving member 102 comprises a fixed part 1021 and a pushable part 1022, that is, the pushable part 1022 can extend or retract relative to the fixed part 1021. In the figure, the deviation rectifying driving member 102 is an electric push rod, which has a small volume and is convenient to arrange. The shell of the electric push rod is the fixed part 1021, and the push rod of the electric push rod is the pushable part 1022. In actual implementation, the deviation rectifying driving member 102 is not limited to an electric push rod, and for example, can also be a pneumatic cylinder, a hydraulic cylinder or the like.

[0050] The deviation rectifying transmission part 103 comprises a driving part 1031, a driven part 1032 and a linkage part 1033. The pushable part 1022 is fixedly connected to the driving part 1031, and the driving part 1031 is fixedly connected to the deviation rectifying roller frame 1042 of one of the deviation rectifying rollers 104. When the pushable part 1022 extends or retracts, the driving part 1031 can be driven to swing, and the driving part 1031 swinging drives the deviation rectifying roller 104 to rotate relative to the deviation rectifying support 101. Each of the remaining deviation rectifying rollers 104 is fixedly connected to one of the driven parts 1032. The driving part 1031 and each of the driven parts 1032 are ball-hinged to the linkage part 1033, so that the driven parts 1032 are linked to the driving part 1031 through the linkage part 1033. When the driving part 1031 swings under the drive of the pushable part 1022, it will drive each of the driven parts 1032 to swing through the linkage part 1033, and the driven part 1032 swinging drives the connected deviation rectifying roller 104 to rotate relative to the deviation rectifying support 101. Figure 2In the middle, the driving part 1031 and the two driven parts 1032 are rod-shaped structures, the driving part 1031 and the two driven parts 1032 are parallel, and one end of the driving part 1031 and the two driven parts 1032 ( Figure 2 Both the middle and left ends are equipped with ball heads. The linkage part 1033 is roughly "L"-shaped and has three ball head holes arranged in a triangle. The three ball head holes respectively mate with the ball heads at one end of the driving part 1031 and the two driven parts 1032, thereby realizing the ball joint connection between the driving part 1031 and the driven parts 1032 and the linkage part 1033. In actual implementation, the positions of the ball heads and the matching ball head holes can be interchanged, and the shapes of the linkage part 1033, the driving part 1031, and the driven part 1032 can be flexibly designed according to actual needs.

[0051] The aforementioned correction device 1 uses multiple correction rollers 104 to correct the deviation together, resulting in a good correction effect. The driving part 1031 of the correction transmission unit 103 is fixedly connected to the pushing part 1022 of the correction drive member 102. The driving part 1031 and the driven part 1032 of the correction transmission unit 103 are linked through the linkage part 1033 and are connected to the linkage part 1033 by a ball joint. Compared with gear transmission, this structure is simpler, thus reducing construction costs. It also has better transmission stability, resulting in lower noise and higher correction accuracy. Furthermore, it requires no maintenance, thus reducing operating costs.

[0052] In some embodiments, such as Figure 2 and Figure 3 As shown, the correction bracket 101 of the correction device 1 is fixedly connected to the inherent first fixed frame 304 of the conveyor belt 3. By modifying the conveyor roller frame of the inherent conveyor roller 303 of the conveyor belt 3 into a rotating part plus a fixed part, the inherent conveyor roller 303 of the conveyor belt 3 becomes the correction roller 104. The modified rotating part serves as the correction roller frame 1042, and the modified fixed part serves as the correction bracket 101. The correction roller 104 is modified from the inherent conveyor roller 303 of the conveyor belt 3, which is more conducive to reducing construction costs. Furthermore, in this case, the correction drive 102 and the correction roller 104 can be located on opposite sides of the first fixed frame 304, the correction drive 102 and the linkage part 1033 are located on the same side of the first fixed frame 304, and the driving part 1031 and the driven part 1032 pass through the first fixed frame 304. In this way, the correction drive 102 and the linkage part 1033 will not interfere with the rotation of the correction roller 104.

[0053] In some embodiments, such as Figure 5As shown, the deviation rectifying device 1 further comprises a second fixing frame 105, the deviation rectifying support 101 is fixedly connected to the second fixing frame 105, the second fixing frame 105 is fixedly connected to the truss 302, the second fixing frame 105 and the first fixing frame 304 are arranged in a spaced manner, and the adhesive tape 301 passes through the second fixing frame 105. Further, in this case, the deviation rectifying driving member 102 and the deviation rectifying roller 104 can be respectively located on opposite sides of the second fixing frame 105, the deviation rectifying driving member 102 and the linkage part 1033 are located on the same side of the second fixing frame, and the driving part 1031 and the driven part 1032 pass through the second fixing frame 105, so that the deviation rectifying driving member 102 and the linkage part 1033 do not interfere with the rotation of the deviation rectifying roller 104.

[0054] The deviation rectifying system provided in the present application will be introduced below.

[0055] The deviation rectifying system provided in the present application comprises a deviation rectifying device, a detection device 2 and a control device.

[0056] As shown in the drawings, Figure 6 The detection device 2 comprises a plurality of sensors 201 arranged in a circumferential direction of the adhesive tape 301 in sequence, and the plurality of sensors 201 are used to detect the distance between the sensor and the region of the adhesive tape 301 directly opposite to the sensor. With the deflection of the adhesive tape 301, the lapped region 301a of the adhesive tape 301 will be directly opposite to different sensors.

[0057] The control device is in communication connection with the plurality of sensors 201, and the control device can obtain the deflection condition of the adhesive tape 301 according to the output signals of the plurality of sensors 201. The distance detected by the sensor 201 when the sensor 201 is directly opposite to the lapped region 301a of the adhesive tape 301 is smaller than the distance detected by the sensor 201 when the sensor 201 is not directly opposite to the lapped region 301a of the adhesive tape 301, so the current sensor 201 directly opposite to the lapped region 301a of the adhesive tape 301 can be determined according to the difference between the two distances, and the position of the current lapped region 301a of the adhesive tape 301 can be determined according to the position of the sensor 201 directly opposite to the lapped region 301a of the adhesive tape 301, so as to determine the deflection condition of the adhesive tape 301.

[0058] The control device is also in communication connection with the deviation rectifying driving member of the deviation rectifying device, and the control device can control the deviation rectifying driving member according to the deflection condition of the adhesive tape 301. For example, when the deviation rectifying driving member comprises a pushing part, if the adhesive tape 301 does not deflect, the pushing part of the deviation rectifying driving member does not act, and if the adhesive tape 301 deflects, the pushing part of the deviation rectifying driving member is controlled to extend or retract according to the deflection direction of the adhesive tape 301, and the extension distance or retraction distance of the pushing part of the deviation rectifying driving member is controlled according to the deflection angle of the adhesive tape 301.

[0059] The above deviation rectifying system can realize automatic deviation rectification, and avoid the problem of time-consuming and laborious manual deviation rectification.

[0060] In some embodiments, the deviation rectifying device adopts the deviation rectifying device 1 provided in the present application.

[0061] In some embodiments, the sensor 201 adopts an ultrasonic sensor, which has high detection accuracy and precision.

[0062] In some embodiments, as shown in Figure 6 The detection device 2 includes a detection bracket 202, which is coaxial with the adhesive tape 301 and surrounds the outer periphery of the adhesive tape 301. The detection bracket 202 is fixed to the truss 302, so that an additional platform is not needed to fix the detection bracket 202. The plurality of sensors 201 are fixed to the detection bracket 202. In the figure, eight sensors 201 are provided, which are numbered as No. ① sensor, No. ② sensor, No. ③ sensor, No. ④ sensor, No. ⑤ sensor, No. ⑥ sensor, No. ⑦ sensor, and No. ⑧ sensor in the instantaneous clockwise direction. The detection bracket 202 is an octagonal frame, and the eight sensors 201 are fixed to the inner sides of the eight frame edges of the octagonal frame, respectively. Adjacent two sensors 201 are approximately 45°.

[0063] In some embodiments, the control device includes a measurement module, a data processing module, a judgment module, and a control module.

[0064] The measurement module is in communication connection with the plurality of sensors 201, and can convert the distance between each sensor 201 and the region of the adhesive tape 301 directly opposite to the sensor 201 according to the output signal of each sensor 201.

[0065] The data processing module is in communication connection with the measurement module, and can calculate the difference between the distance between each sensor 201 and the region of the adhesive tape 301 directly opposite to the sensor 201 detected in the previous detection time period and the distance between each sensor 201 and the region of the adhesive tape 301 directly opposite to the sensor 201 detected in the next detection time period. In some embodiments, the data processing module includes a sorting submodule. Each sensor 201 performs multiple detections in the same detection time period, and the sorting submodule sorts the multiple detection data corresponding to each sensor 201 in the same detection time period in size and takes the middle value as the detection data of each sensor 201 in the detection time period. In this way, the detection accuracy can be improved. For example, each sensor 201 performs five detections in a detection time period, and each sensor 201 obtains five detection data by performing detection every 2 seconds. The sorting submodule sorts the five detection data corresponding to each sensor 201 in size from small to large, takes the middle detection data as the detection data of each sensor 201 in the detection time period, and calculates the difference based on the middle detection data.

[0066] The judgment module is in communication connection with the data processing module, and can compare the difference corresponding to each sensor 201 with a preset value. The distance detected by the sensor 201 when it is directly opposite the lap joint area 301a of the adhesive tape 301 is smaller than the distance detected by the sensor 201 when it is not directly opposite the lap joint area 301a of the adhesive tape 301, and is close to the wall thickness of one layer of the adhesive tape 301. Therefore, the preset value can be set to be equal to or slightly smaller than the wall thickness of one layer of the adhesive tape 301. If the adhesive tape 301 is not deviated, the difference corresponding to each sensor 201 is smaller than the preset value. If the adhesive tape 301 is deviated, the difference corresponding to one of the sensors 201 is greater than or equal to the preset value. Therefore, the sensor 201 whose difference is greater than or equal to the preset value is directly opposite the lap joint area 301a of the adhesive tape 301.

[0067] The control module is in communication connection with the judgment module, and can determine the deflection of the adhesive tape 301 according to the position of the sensor 201 whose difference is greater than the preset value. For example, if the sensor 201 whose difference is greater than the preset value is the No. 4 sensor 201 in the figure, the lap joint area 301a of the current adhesive tape 301 is approximately located at the position directly opposite the No. 4 sensor 201, and it is determined that the adhesive tape 301 is deflected clockwise by 135°. The control module is also in communication connection with the deviation correction driving member of the deviation correction device, and can control the deviation correction driving member of the deviation correction device according to the deflection of the adhesive tape 301.

[0068] In some embodiments, the control module includes a plurality of sub-control modules. Each sub-control module has a parameter preset to limit the action amplitude of the deviation correction driving member. Each sub-control module is in communication connection with the deviation correction driving member of the deviation correction device, and can control the deviation correction driving member to act according to the preset parameter. The plurality of sub-control modules are in communication connection with the judgment module, and the action amplitudes of the deviation correction driving members limited by the parameters preset in the plurality of sub-control modules decrease successively. When the deflection angle of the adhesive tape exceeds a preset angle, the plurality of sub-control modules can successively control the deviation correction driving member to act and the action amplitudes decrease successively according to the current deflection of the adhesive tape. In this way, gradual and progressive deviation correction can be realized, and the deviation correction effect is better.

[0069] For example, two sub-control modules are provided, namely a first sub-control module and a second sub-control module, and the action of the deviation rectifying driving member is the extension and retraction action of the pushing part. The first sub-control module is preset with an extension and retraction time length of 3 seconds, the second sub-control module is preset with an extension and retraction time length of 1 second, and the preset angle is 30°. When it is judged that the adhesive tape 301 deflects clockwise by more than 30°, the first sub-control module first controls the pushing part of the deviation rectifying driving member to extend for 3 seconds. Then, the detection device 2 detects the deflection of the adhesive tape 301 again. If it is judged that the adhesive tape 301 still deflects clockwise by more than 30°, the second sub-control module controls the pushing part of the deviation rectifying driving member to extend for 1 second. If it is judged that the adhesive tape 301 deflects counterclockwise, the second sub-control module controls the pushing part of the deviation rectifying driving member to retract for 1 second.

[0070] In some embodiments, the deviation rectifying system comprises an alarm. When it is judged that the adhesive tape 301 deflects by more than the preset angle, the alarm gives an alarm until the alarm stops when the deflection angle of the adhesive tape 301 is less than the preset angle. The alarm can be a sound alarm and / or a picture alarm. Two alarms can be provided, namely a first alarm and a second alarm. When it is judged that the adhesive tape 301 deflects clockwise by more than the preset angle, the first alarm gives an alarm. When it is judged that the adhesive tape 301 deflects counterclockwise by more than the preset angle, the second alarm gives an alarm.

[0071] In some embodiments, the deviation rectifying system comprises a plurality of detection devices 2 and a plurality of deviation rectifying devices. The plurality of detection devices 2 are arranged in sequence along the axial direction of the adhesive tape 301, and the plurality of deviation rectifying devices are arranged between adjacent detection devices 2 and after the last detection device 2. The interval distance between adjacent detection devices 2 can be designed according to the curvature of the adhesive tape 301. In the section with small curvature of the adhesive tape 301, the interval distance between adjacent detection devices 2 is large, for example, 50 m. When the interval distance between adjacent detection devices 2 is 50 m, a deviation rectifying device can be arranged every 20 m after each detection device 2. In the section with large curvature of the adhesive tape 301, the interval distance between adjacent detection devices 2 is small, for example, 30 m. When the interval distance between adjacent detection devices 2 is 30 m, a deviation rectifying device can be arranged every 10 m after each detection device 2. By reasonably designing the arrangement interval of the detection devices 2 and the deviation rectifying devices, the reliability and stability of the deviation rectifying system can be guaranteed.

[0072] The deviation rectifying method provided in the present application is described below.

[0073] The deviation rectifying method provided in the present application comprises the following steps:

[0074] S1, detecting the distance between the sensor and the region of the adhesive tape 301 directly opposite to the sensor by using a plurality of sensors arranged in sequence along the circumferential direction of the adhesive tape 301.

[0075] S2, calculating the difference between the distance between each sensor and the area of the adhesive tape 301 detected in the previous detection period and the distance between each sensor and the area of the adhesive tape 301 detected in the next detection period.

[0076] S3, comparing the difference corresponding to each sensor with a preset value. When the sensor 201 is opposite the overlap area 301a of the adhesive tape 301, the distance detected is smaller than the distance detected when the sensor 201 is not opposite the overlap area 301a of the adhesive tape 301, and the distance detected is close to the wall thickness of one layer of the adhesive tape 301, so the preset value can be set to be equal to or slightly smaller than the wall thickness of one layer of the adhesive tape 301. If the adhesive tape 301 is not deflected, the difference corresponding to each sensor is smaller than the preset value, and if the adhesive tape 301 is deflected, the difference corresponding to one of the sensors is greater than or equal to the preset value, so that the sensor can be determined as the sensor currently opposite the overlap area 301a of the adhesive tape 301.

[0077] S4, determining the deflection of the adhesive tape 301 according to the position of the sensor whose difference is greater than the preset value.

[0078] S5, controlling the deviation driving member of the deviation device according to the deflection of the adhesive tape 301.

[0079] In some embodiments, in S2, each sensor 201 performs multiple detections in the same detection period, sorts the multiple detection data corresponding to each sensor 201 in the same detection period according to size, takes the middle data as the detection data of each sensor 201 in the detection period, and calculates the difference based on the middle data. This design can improve detection accuracy. For example, each sensor 201 performs five detections in a detection period, one detection every 2 seconds, and each sensor 201 obtains five detection data. The five detection data corresponding to each sensor 201 are sorted from small to large, and the middle data is taken as the detection data of each sensor 201 in the detection period.

[0080] In some embodiments, in S5, when the deflection angle of the adhesive tape exceeds a preset angle, the deviation driving member is controlled to act according to the current deflection of the adhesive tape, and the action amplitude decreases in turn, and the current deflection of the adhesive tape is detected again before the last control and after the previous control. In this way, gradual and progressive deviation correction can be achieved, and the deviation correction effect is better.

[0081] For example, the action of the deviation rectifying driving member is the extension and retraction of the pushing part, the preset angle is 30°, when it is judged that the adhesive tape 301 is deflected counterclockwise more than 30°, the pushing part of the deviation rectifying driving member is first controlled to retract for a long distance, then the deflection of the adhesive tape 301 is detected again, if it is judged that the adhesive tape 301 is still deflected clockwise more than 30°, the pushing part of the deviation rectifying driving member is controlled to continue retracting for a short distance, if it is judged that the adhesive tape 301 is deflected clockwise, the pushing part of the deviation rectifying driving member is controlled to extend for a short distance.

[0082] In some embodiments, when the deflection angle of the adhesive tape exceeds the preset angle, an alarm is issued to prompt the on-site personnel.

The above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that, for those skilled in the art, without departing from the principles of the present application, some improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the present application.
