Under the normal motion state of the conveying belt, namely when the circular tube formed by the conveying belt is in the centering operation state, the axial direction of the rounding carrier roller 211 is tangent to the rounding surface of the tube belt. In the above state, the axis of the circular tube formed by the conveyor belt is defined as the first axis. The axis of the rounding idler 211 is perpendicular to the first axis.
In the present embodiment, a plurality of rounded idlers 211 together form one polygonal idler unit 200.

The linear CCD recognizer can be used for conveniently and quickly recognizing the deviation condition of the conveying belt.
The deviation adjusting unit 300 includes a driving member 310, a connecting seat 320, and a deviation adjusting roller 330. The rotating shaft of the driving member 310 is connected to the connecting base 320, and the deflection adjusting roller 330 is disposed on the connecting base 320.
The control unit controls the driving element 310 to drive the connecting seat 320 and the deflection adjusting carrier roller 330 to deflect according to the deflection degree of the positioning identification belt obtained by the recognition of the recognition unit, and the deflection adjusting carrier roller 330 deflects to drive the conveying belt to deflect back to be positive, so that the automatic deflection adjustment of the circular pipe part of the pipe belt machine is realized.
In a normal motion state of the conveyor belt, that is, when a circular tube formed by the conveyor belt is in a centering operation state, the axis direction of the deviation adjusting carrier roller 330 is tangent to the circular surface of the conveyor belt. In the above state, the axis of the deflection adjusting idler 330 is defined as the second axis, and the first axis is perpendicular to the second axis. In the state that the conveying belt does not send the deflection, only form the frictional force along the direction of the first axis between the deviation adjusting idler 330 and the conveying belt, the deviation adjusting idler 330 does not produce the deviation adjusting function, and the conveying belt runs normally.
In this embodiment, the drive member 310 is preferably a steering engine. The driving member 310 is connected to the support plate 110 by the fixing plate 340. The fixing plate 340 and the support plate 110 form an L-shaped structure. The axial direction of the rotation axis of the driving member 310 is perpendicular to the first axis and the second axis.
The connection holder 320 includes a base 321 and a swing link 322. The driving member 310 deflects by driving the connection seat 320, thereby deflecting the deflection regulating roller 330.
The deflection regulating idler 330 is disposed on the base 321. Preferably, both ends of the base 321 are provided with side plates 323, and both ends of the roller of the deviation adjusting roller 330 are connected with the two side plates 323. Therefore, when the base 321 deflects, the deflection regulating rollers 330 deflect to the same extent at the same time, and the deflection regulating rollers 330 can rotate by themselves under the friction force of the conveying belt.
One end of the swing link 322 is connected to the driving element 310, and the other end is connected to the base 321, and the swing link 322 makes the offset adjusting roller 330 move away from the second axis under the driving of the driving element 310.
The output shaft of the driving member 310 is connected to a swing link 322. The pendulum 322 forms a form of operation that rotates about the output shaft of the steering engine. Through the setting of pendulum rod 322, change the rotation of the output shaft of steering wheel into deflection motion, realize the deflection motion of base 321 and tuningout bearing roller 330.
Preferably, the bottom of the base 321 is provided with a guide groove 324, the connection end of the swing rod 322 and the base 321 is provided with a guide block 325, and the guide block 325 is slidably connected to the guide groove 324. In this embodiment, the swing link 322 is disposed at the bottom of the base 321, the guide slot 324 is a strip-shaped slot extending along the second axial direction, and the guide block 325 is located in the guide slot 324. When the shaft of the driving member 310 drives the swing rod 322 to rotate, the guide block 325 moves in the guide groove 324, and the driving base 321 deflects, thereby driving the deflection adjusting roller 330 to deflect.
Further, a bearing is arranged at the joint of the guide block 325 and the swing rod 322, so that the movement is more stable in the deflection movement process.
Further, the connecting seat 320 further includes a positioning rod 326, the positioning rod 326 is disposed on the fixing plate 340, and the positioning rod 326 is disposed along a direction of the second axis. The positioning rod 326 is rotatably connected with the base 321 of the connecting seat 320. The presence of detent post 326 limits the degree of deflection of attachment socket 320. The joint between the swing link 322 and the rotation shaft of the driving member 310 is defined as a first pivot, the joint between the base 321 and the positioning support rod 326 is defined as a second pivot, and the connecting seat 320 only deflects between the first pivot and the second pivot. The stability of the whole deflection adjusting unit structure is ensured, and excessive deflection is avoided. In addition, the positioning strut 326 and the driving member 310 together form a positioning mechanism of the deviation adjusting idler 330, and the first fulcrum and the second fulcrum form a fixed point of the deviation adjusting idler 330, so that the deviation of the deviation adjusting idler 330 caused by the deflection of the conveying belt is avoided.
Preferably, the deviation-adjusting carrier roller 330 is disposed below the conveying belt, and the deviation-adjusting carrier roller 330 bears more gravity of the conveying belt, so that the friction force between the deviation-adjusting carrier roller 330 and the conveying belt is the largest, and when the deviation-adjusting carrier roller 330 deflects, the deviation of the conveying belt can be effectively adjusted.
Further, by adjusting the structure of the guide groove 324 or by degree control, the maximum angle of deviation of the axis of the idler of the deviation-adjusting idler 330 from the second axis is limited to 90 degrees. Further, the maximum angle of deviation of the axis of the idler roller of the deviation-adjusting idler 330 from the second axis is limited to 45 degrees. The optimal deviation adjusting effect is achieved through angle adjustment and control.
Further, along the conveying direction of the conveying belt, the recognition unit and the deviation adjusting unit 300 are sequentially provided. The identification unit is arranged at the upstream position of the deviation adjusting unit 300, so that the deviation pre-adjusting function can be realized, and the deviation adjusting effect is good.
The control unit mainly receives and controls the data of the identification unit and the offset adjustment unit 300 through a single chip microcomputer. Specifically, a stm32f103c8t6 single chip microcomputer is used. Through electric control deviation adjustment, single chip microcomputer control is adopted, the integration is high, command control is achieved, and the accuracy is higher. In the aspect of collecting information sources, the time consumption is shorter, the feedback time is short, the timeliness is strong, the deviation is corrected in advance, and the reliability is high.
The embodiment also provides a control method of the automatic pipe part deviation adjusting device 10 of the pipe-strip machine, which comprises the following steps:
s1, forming a positioning identification belt on the conveying belt along the axial direction of the round tube formed by the conveying belt;
s2, the identifying unit detects the deflection displacement of the positioning identification band and transmits the deflection data to the control unit;
s3, the control unit controls the deflection unit to deflect according to the deflection data, so that the conveying belt deflects to return to the positive state.
Referring to fig. 5, the operation steps of the control unit include:
acquiring sampling data of the identification unit, wherein the sampling data comprises an initial position of a positioning identification band and a sampling position of the positioning identification band;
judging an operation mode, wherein the operation mode comprises an automatic mode and a manual mode;
in the automatic mode state: reading sampling data, obtaining a deflection adjusting angle through a PID algorithm, sending a deflection instruction to a deflection adjusting unit according to the deflection adjusting angle, and controlling the deflection adjusting unit to deflect so as to enable the conveying belt to return to be positive;
in the manual mode state: and manually analyzing the deflection angle of the identification unit, and controlling the deflection adjustment unit to deflect so as to enable the conveyor belt to be aligned.
And under the automatic mode state, the output value of the PID algorithm is PWM pulse width, and the deflection angle of the deflection regulating unit is controlled through the PWM pulse width. Namely, the PWM pulse width is converted after the processing of the PID control algorithm, different pulse widths correspond to different steering engine angles, for example, the 0.5 ms-2.5 ms pulse width is set to deflect-90 DEG to +90 DEG corresponding to the steering engine.
