[0029] The following is combined with Figure 1-10 This application is described in further detail.

[0030] A fully automatic multi-caliber pipe bending intelligent conveyor, refer to Figure 1 As shown, it includes a frame 1, a steel pipe lifting and feeding mechanism 2, a pipe seam detection mechanism 3 and a steel pipe transfer mechanism 4; the steel pipe lifting and feeding mechanism 2, the pipe seam detection mechanism 3 and the steel pipe transfer mechanism 4 are all arranged on the frame 1, and the pipe seam detection mechanism 3 is arranged between the steel pipe lifting and feeding mechanism 2 and the steel pipe transfer mechanism 4.

[0031] The steel pipes are placed in the steel pipe lifting and loading mechanism 2, which transports the steel pipes one by one to the pipe seam detection mechanism 3. After the pipe seam detection mechanism 3 completes the detection, when it is detected that the steel pipes have no cracks, the steel pipe transfer mechanism 4 transfers the steel pipes in the pipe seam detection mechanism 3 to the subsequent pipe bending machine for processing. When cracks are detected in the steel pipes, the steel pipe transfer mechanism 4 transfers the steel pipes for recycling.

[0032] The steel pipe lifting and feeding mechanism 2 is described below.

[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown, the steel pipe lifting and feeding mechanism 2 includes a steel pipe silo 21 and a steel pipe lifting and ejecting part 22. The steel pipe silo 21 is arranged on the frame 1. The steel pipe silo 21 is a square box body. The upper part of the steel pipe silo 21 is open. A storage cavity 23 is arranged in the steel pipe silo 21. The bottom surface of the steel pipe silo 21 is inclined. When the steel pipe is placed in the steel pipe silo 21, the steel pipe can roll to the lowest point of the bottom surface of the steel pipe silo 21.

[0034] Two adjusting rods 24 are horizontally fixed in the steel pipe silo 21, and the two adjusting rods 24 are arranged in parallel. Two adjusting blocks 25 are slidably installed on the two adjusting rods 24, and an adjusting plate 26 is fixed on each adjusting block 25. The adjusting plate 26 is inserted into the steel pipe silo 21, and a storage cavity 23 for storing steel pipes is formed between the two adjusting plates 26. An adjusting bolt 27 whose end is against the adjusting rod 24 is threadedly connected to the adjusting block 25. The length space of the storage cavity 23 can be adjusted by the adjusting bolt 27 and the adjusting plate 26, so as to adapt to the placement of steel pipes of different lengths and specifications and different calibers and carry out subsequent lifting and loading.

[0035] The steel pipe lifting and ejecting part 22 is arranged at the lowest point of the inclination of the bottom surface of the steel pipe silo 21, and is used to eject the steel pipe from the steel pipe silo 21 into the pipe seam detection mechanism 3. The steel pipe lifting and ejecting part 22 includes an ejection bracket 221 and a plurality of ejection rods 222, and the ejection bracket 221 is slidably mounted on the outer wall of the steel pipe silo 21 in the vertical direction. In another embodiment, the ejection bracket 221 can also be slidably mounted on the frame 1 in the vertical direction.

[0036] A plurality of ejector rods 222 are fixedly arranged on the ejector bracket 221, a plurality of ejector rods 222 are arranged in the vertical direction, a plurality of ejector rods 222 are arranged at intervals, an ejector hole 225 is arranged at the lowest point of the bottom surface of the steel pipe silo 21, the number of the ejector holes 225 is the same as the number of the ejector rods 222, and the positions of the ejector holes 225 correspond one to one with the positions of the ejector rods 222, and an ejector lifting cylinder 224 for driving the ejector bracket 221 to move up and down is arranged on the steel pipe silo 21.

[0037] The end of the ejector rod 222 is provided with an ejector slope 223, and the inclination direction of the ejector slope 223 is the same as the inclination direction of the bottom surface of the steel pipe silo 21. The setting of the ejector slope 223 ensures that the steel pipe is lifted and ejected with higher stability.

[0038] As a result, the ejection lifting cylinder 224 drives the ejection frame to move upward, and the ejection rod 222 extends from the ejection hole 225. The ejection rod 222 ejects a steel pipe in the storage chamber 23 until the upper opening of the steel pipe silo 21, and the steel pipe is ejected from the steel pipe silo 21 and falls into the pipe seam detection part 34.

[0039] It is worth noting that the method of ejecting the steel pipe by the ejection rod 222 can be applicable to the lifting and ejection of steel pipes of different calibers, and the steel pipe ejection efficiency is high, the smoothness is good, and the degree of intelligence is high.

[0040] In order to ensure that the ejector rod 222 only ejects one steel pipe at a time, a plurality of ejector resistance blocks 28 are arranged at intervals on the inner wall of the steel pipe silo 21. The plurality of ejector resistance blocks 28 are arranged on the inner wall on the side of the lowest inclined bottom surface of the steel pipe silo 21. The surface of the ejector resistance block 28 in contact with the steel pipe is provided with an outwardly protruding expansion section 281. The expansion section 281 is arranged on the upper part of the ejector resistance block 28. Therefore, when two steel pipes are stacked on the ejector rod 222, when the upper stacked steel pipe contacts the expansion section 281, the upper steel pipe will roll down from the ejector rod 222.

[0041] It is worth mentioning that a guide block 29 is provided on the top outer wall of the steel pipe silo 21, and a guide slope 291 is provided on the guide block 29. The inclination direction of the guide slope 291 is toward the pipe seam detection mechanism 3. Through the setting of the guide block 29, it is convenient for the steel pipe to be pushed out from the upper opening of the steel pipe silo 21 and roll into the pipe seam detection mechanism 3.

[0042] The pipe seam detection mechanism 3 will be described below.

[0043] Reference Figure 5 and Figure 6As shown, the pipe seam detection mechanism 3 can be set on the frame 1, and the pipe seam detection mechanism 3 can also be set on the steel pipe silo 21. This embodiment takes the pipe seam detection mechanism 3 set on the steel pipe silo 21 as an example for explanation. The pipe seam detection mechanism 3 includes a steel pipe receiving platform 31, and a steel pipe clamping rotating part arranged on the steel pipe receiving platform 31. The steel pipe receiving platform 31 is provided with a pipe seam detection part 34.

[0044] The steel pipe receiving platform 31 includes a first receiving bracket 311 and a second receiving bracket 312. The first receiving bracket 311 and the second receiving bracket 312 are arranged on the frame 1. In another embodiment, the steel pipe receiving platform 31 is arranged on the steel pipe silo 21 to facilitate receiving the steel pipe. Figure 5 In the description, the steel pipe receiving platform 31 is arranged on the steel pipe silo 21 as an example.

[0045] The first receiving bracket 311 and the second receiving bracket 312 are arranged at intervals, the first receiving bracket 311 is provided with a first receiving block 313, the second receiving bracket 312 is provided with a second receiving block 314, the upper ends of the first receiving block 313 and the second receiving block 314 are both provided with a V-shaped receiving groove 315, the first receiving block 313 and the second receiving block 314 are respectively used to receive the two ends of the steel pipe.

[0046] The steel pipe clamping and rotating portion includes a steel pipe clamping member 32 provided on the first receiving bracket 311 , and a steel pipe rotating member 33 provided on the second receiving bracket 312 .

[0047] Reference Figure 6 and Figure 7a As shown, the steel pipe clamping component 32 includes a steel pipe clamping cylinder 321 arranged on the first receiving bracket 311, and a first mounting sleeve 322 fixed on the output rod of the steel pipe clamping cylinder 321, and the end of the first mounting sleeve 322 is rotatably mounted with a first clamping head 323, and the first clamping head 323 is provided with a first clamping cone surface 324.

[0048] Reference Figure 6 and Figure 7b As shown, the steel pipe rotating component 33 includes a steel pipe rotating motor 331 arranged on the second supporting bracket 312, and a second mounting sleeve 332 fixed on the output rod of the steel pipe rotating motor 331, and a second clamping head 333 is coaxially fixed to the end of the second mounting sleeve 332, and a second clamping cone surface 334 is arranged on the second clamping head 333.

[0049] Therefore, when the steel pipe falls onto the steel pipe receiving platform 31, the two ends of the steel pipe are received by the first receiving block 313 and the second receiving block 314 respectively. At this time, the steel pipe clamping cylinder 321 drives the first clamping head 323 to move, and the first clamping head 323 is pressed against one end of the steel pipe through the first clamping cone surface 324, and after pushing the steel pipe to move a certain distance, the other end of the steel pipe is pressed against the second clamping head 333. At this time, the steel pipe rotating motor 331 drives the steel pipe to rotate, and the pipe seam detection unit 34 can perform pipe seam detection on the steel pipe.

[0050] The pipe seam detection unit 34 is arranged on the second receiving bracket 312. The pipe seam detection unit 34 includes a detection mounting bracket 341 and a detection sensor 342 arranged on the detection mounting bracket 341. The detection head of the detection sensor 342 is arranged toward one side of the steel pipe. In one embodiment, the detection sensor 342 adopts an eddy current sensor, and the pipe seam detection of the steel pipe can be realized by the eddy current sensor.

[0051] In one embodiment, referring to Figure 6 As shown, the first receiving bracket 311 is slidably mounted on the steel pipe silo 21, and the steel pipe silo 21 is provided with a first driving part 35 for driving the first receiving bracket 311 to slide. The first driving part 35 includes a driving fixed seat 351 arranged on the steel pipe silo 21, and a driving screw 352 with two ends rotatably mounted on the driving fixed seat 351, a driving threaded seat 353 is threadedly connected to the driving screw 352, and the driving threaded seat 353 is fixed on the first receiving bracket 311, and a receiving driving motor 429354 is arranged on the driving fixed seat 351, and the output shaft of the receiving driving motor 429354 is connected to the end of the driving screw 352.

[0052] When performing pipe seam detection on steel pipes of different lengths and specifications, the drive screw 352 is driven to rotate by the receiving drive motor 429354, thereby driving the first receiving bracket 311 to slide, so that the position of the first receiving bracket 311 can be changed to receive steel pipes of different lengths and specifications.

[0053] In one embodiment, referring to Figure 6 As shown, the second receiving bracket 312 is slidably installed on the frame 1, and the frame 1 is provided with a second driving part 36 for driving the second receiving bracket 312 to slide. The second driving part 36 includes a receiving driving cylinder 361, and the output rod of the receiving driving cylinder 361 is connected to the second receiving bracket 312. The receiving driving cylinder 361 drives the second receiving bracket 312 to slide toward the side of the first receiving bracket 311, so as to facilitate the second clamping head 333 to be pressed against the end of the steel pipe.

[0054] Therefore, after the steel pipe completes the pipe seam detection in the pipe seam detection mechanism 3, the steel pipe will be transferred to the next process by the steel pipe transfer mechanism 4. For example, when no pipe seam is detected on the steel pipe, the steel pipe transfer mechanism 4 transfers the steel pipe to the steel pipe bending machine. When a pipe seam is detected on the steel pipe, the steel pipe transfer mechanism 4 sorts and recycles the steel pipe.

[0055] Next, the steel pipe transferring mechanism 4 will be described.

[0056] Reference Figure 8 , Fig. 9 and Fig.10 As shown, the steel pipe transfer mechanism 4 includes a transfer base 41 and a transfer clamping portion 42 arranged on the transfer base 41 , and the transfer clamping portion 42 is used to clamp and transfer the steel pipe in the steel pipe receiving platform 31 .

[0058] The axial direction of the connecting shaft 424 is perpendicular to the axial direction of the first rotating crank 422 , and the axial direction of the second rotating crank 423 is perpendicular to the axial direction of the connecting shaft 424 , so that the first rotating crank 422 is parallel to the second rotating crank 423 .

[0059] The clamping jaw mounting frame 421 is provided with a first rotating motor 426 for driving the first rotating crank 422 to rotate, and the first rotating crank 422 is provided with a second rotating motor 427 for driving the connecting shaft 424 to rotate. The first rotating motor 426 drives the first rotating crank 422 to rotate, and the second rotating motor 427 drives the connecting shaft 424 to rotate. Therefore, by providing the first rotating motor 426 and the second rotating motor 427, not only the occupied volume of the transfer clamping jaw portion 42 is reduced, but also the transfer distance of the transfer clamping jaw portion 42 is not limited.

[0060] Reference Fig.10As shown, the clamping member 425 includes a clamping jaw mounting seat 4251, a first clamping jaw 4252 fixedly mounted on the clamping jaw mounting seat 4251, and a second clamping jaw 4253 hingedly mounted on the clamping jaw mounting seat 4251.

One end of 254 is hingedly connected to the second clamping jaw 4253, and a clamping jaw cylinder 4255 is arranged on the clamping jaw mounting seat 4251. The cylinder body of the clamping jaw cylinder 4255 is hingedly connected to the clamping jaw mounting seat 4251, and the output rod of the clamping jaw cylinder 4255 is hingedly connected to the other end of the driving connecting rod 4254. The other end of the driving connecting rod 4254 can be driven to swing through the clamping jaw cylinder 4255, thereby realizing the clamping action of the first clamping jaw 4252 and the second clamping jaw 4253.

[0061] Among them, in the connection between the middle part of the driving connecting rod 4254 and the clamping jaw mounting seat 4251, a waist-shaped sliding groove 4256 is provided on the clamping jaw mounting seat 4251, and a rolling wheel is rotatably installed in the middle part of the driving connecting rod 4254, and the rolling wheel slides in cooperation with the waist-shaped sliding groove 4256.

The driving motor 429 can drive the driving gear to rotate, and the driving gear meshes with the driving rack 428, thereby driving the clamping jaw mounting frame 421 to slide along the transfer base 41, thereby changing the position of the transfer clamping jaw portion 42 on the transfer base 41, so as to facilitate the transfer clamping jaw portion 42 to clamp the steel pipe on the pipe seam detection portion 34.

[0063] In the present application, the steel pipe transfer mechanism 4 is an intelligent manipulator structure, the clamping claw member 425 clamps firmly and stably, and the steel pipe transfer mechanism 4 is used instead of the traditional truss. It not only has high precision and high clamping efficiency, but also meets the clamping and transfer requirements of steel pipes of different calibers. The clamping is firm and stable, and the problem of the traditional truss occupying a large space is solved.

[0064] It is worth noting that a transfer robot 5 is also provided on the transfer base 41. The transfer clamping part 42 delivers the steel pipe to the pipe bending machine for processing.
