[0002] Pipe clamps, also known as internal threaded straight connectors, are a type of plumbing fitting used to connect two externally threaded pipes or fittings of the same nominal diameter. Pipe clamps come in both equal-diameter and reducing-diameter types. Tapping is a crucial step in the manufacturing process of pipe clamps.

[0003] The shape of reducing couplings is irregular. Because they are cylindrical malleable iron pipe fittings with necks, they only have two relatively regular surfaces, namely the two sides of the cylinder: the large end face and the small end face. It is quite difficult to find these two surfaces among many parts. Secondly, due to the processing requirements of the processing machine, the large end face and the small end face must be distinguished when the reducing coupling is loaded, so that the large end face or the small end face enters the processing machine in the specified orientation.

[0004] To achieve fully automated feeding of reducing couplings, posture recognition and correction must be performed during the feeding process so that the reducing couplings can enter the assembly or processing position according to the specified assembly or processing posture.

DETAILED DESCRIPTION

[0032] Referring to Figure 1 , Figure 2The device comprises a stepped feeding unit, a conveying unit 4, an adjusting unit, a turnover feeding unit 3 and a detection control unit; the stepped feeding device in the device comprises a hopper 1 located on a rack 2, which is used for accommodating ferrules; the bottom surface of the hopper 1 is designed to be inclined backward. A plurality of stepped feeding moving plates 5 and stepped feeding static plates 6 are arranged on the rear side of the hopper 1, and the stepped feeding moving plates 5 and the stepped feeding static plates 6 are arranged in sequence at intervals, from front to back, as stepped feeding moving plate 5 - stepped feeding static - stepped feeding moving plate 5 - stepped feeding static …; the stepped feeding static plates 6 are arranged upward in steps from front to back. The stepped feeding moving plate 5 is connected with a lifting cylinder 7 through a lifting rod 8, so that the stepped feeding moving plate 5 can be lifted under the driving of the lifting cylinder 7; the lifting cylinder 7 is preferably two, which are respectively fixed on the two sides of the rack 2 by fixing members, and the lifting of the stepped feeding moving plate 5 can be more stable under the common driving of the two lifting cylinders 7. The height of each stepped feeding moving plate 5 after being lifted is not lower than the height of the adjacent stepped feeding static plate 6 behind it, and the height of each stepped feeding moving plate 5 after being lowered is not higher than the height of the adjacent stepped feeding static plate 6 in front of it. The height of the foremost stepped feeding moving plate 5 after being lowered is not higher than the lowest part of the bottom surface of the hopper 1. The top surface of the stepped feeding moving plate 5 and the stepped feeding static plate 6 is preferably designed to be inclined backward. After adopting such a structure, the hopper 1 with an inclined bottom surface makes the ferrules automatically slide to the last end, so that there are ferrules above the foremost stepped feeding moving plate 5; the lifting cylinder 7 drives the stepped feeding moving plate 5 to rise, at this time, the foremost stepped feeding moving plate 5 drives the ferrules located thereon to rise to the height of the foremost stepped feeding static plate 6, and the ferrules slide from the foremost stepped feeding moving plate 5 to the foremost stepped feeding static plate 6; the lifting cylinder 7 drives the stepped feeding moving plate 5 to descend, when the stepped feeding moving plate 5 behind the foremost stepped feeding static plate 6 descends to the height of the foremost stepped feeding static plate 6, the ferrules on the foremost stepped feeding static plate 6 slide to the stepped feeding moving plate 5 behind it, and then are driven by the stepped feeding moving plate 5 to rise to the stepped feeding static plate 6 behind it, so that the ferrules are lifted step by step. Since the top surface of the stepped feeding moving plate 5 and the stepped feeding static plate 6 is a strip surface, the posture of the ferrules can be automatically adjusted during the lifting process.

[0033] Referring to Figure 1 , Figure 2The conveying unit 4 in the device comprises a conveying track 9 and a vibrating feeder; the conveying track 9 is a U-shaped strip track arranged at the rear end of the stepped feeding device, and the U-shaped conveying track 9 can ensure the posture of the ferrule unchanged when the ferrule is transported thereon. The vibrating feeder is installed at the bottom of the conveying track 9 and controls the transportation of the ferrule on the conveying track 9 by vibration. The height of the conveying track 9 is not higher than the top surface height of the last end stepped feeding static plate 6. After the structure is adopted, the ferrule sent to the last end stepped feeding static plate 6 of the stepped feeding device rolls down to the conveying track 9; due to the adjustment of the posture of the ferrule during lifting, the ferrule is orderly and directionally arranged on the conveying track 9; the vibrating feeder vibrates to drive the ferrule to be transported on the conveying track 9. The rear side of the conveying track 9 is provided with a limiting plate which is arranged in parallel with the conveying track 9, and the limiting plate can prevent the ferrule dropped from the stepped feeding device to the conveying track 9 from falling on other places outside the conveying track 9.

[0034] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4The adjusting unit in the device comprises a fixed frame, a sliding assembly, a rotary cylinder 18 and a rotary seat 21. The fixed frame is fixed between the end of the material conveying track 9 and the inlet of the turnover feeding unit 3. The sliding assembly comprises a sliding rail 19, a sliding block 17 and an adjusting cylinder 20. The sliding rail 19 is installed on the fixed frame, with one end located at the end of the material conveying track 9 and the other end located at the inlet of the turnover feeding unit 3. The sliding block 17 is in sliding cooperation with the sliding rail 19. The sliding block 17 is fixed upward with the rotary cylinder 18. The adjusting cylinder 20 is fixed on the fixed frame, with the cylinder rod of the adjusting cylinder 20 extending towards the inlet of the turnover feeding unit 3 and being fixed with the rotary cylinder 18. Since the rotary cylinder 18 is fixed with the sliding block 17 and the cylinder rod of the adjusting cylinder 20 respectively, the adjusting cylinder 20 can push and pull back the rotary cylinder 18 by extension and retraction, so as to realize the sliding of the rotary cylinder 18 and the sliding block 17 on the sliding rail 19, and further realize the back-and-forth movement of the rotary cylinder 18 between the end of the material conveying track 9 and the inlet of the turnover feeding unit 3. The rotary seat 21 is also a U-shaped strip structure, with the bottom flush with the bottom of the material conveying track 9. The U-shaped both ends and the upper opening of the rotary seat 21 can allow the pipe clamp to enter and exit. The output end of the rotary cylinder 18 extends upward and is connected with the arc-shaped bottom of the rotary seat 21. The rotation of the rotary cylinder 18 in the adjusting unit can realize the reversing of the large end face and the small end face of the pipe clamp. When the adjusting cylinder 20 is not extended, the rotary seat 21 is located at the end of the material conveying track 9, and the openings at both ends of the rotary seat 21 are along the material conveying direction of the material conveying track 9. Since the material conveying track 9 is also U-shaped, the pipe clamp enters from the openings at both ends of the rotary seat 21 and does not change the orientation of the pipe clamp. When the adjusting cylinder 20 is fully extended, the rotary seat 21 reaches the inlet of the turnover feeding unit 3.

[0035] The adjusting unit in the device further comprises a direction identification assembly; the direction identification assembly comprises a direction sensor 10 and an induction baffle 22; the direction sensor 10 is fixed at the rear end of the material conveying track 9, the rear end of the rotating seat 21 when the adjusting cylinder 20 is not extended, the direction sensor 10 is arranged opposite to the large end face or the small end face of the pipe clamp with different diameters on the material conveying track 9, the direction sensor 10 is a proximity switch type sensor, the distance from the direction sensor 10 to the non-empty area of the large end face of the pipe clamp with different diameters is greater than the induction distance of the direction sensor 10, and the distance from the direction sensor 10 to the non-empty area of the small end face of the pipe clamp with different diameters is less than the induction distance of the direction sensor 10. The induction baffle 22 is made of insulating material and is sleeved outside the direction sensor 10 to isolate the interference of other factors. In this way, when the large end face of the pipe clamp with different diameters faces the direction sensor 10, the non-empty area of the large end face of the pipe clamp with different diameters cannot enter the induction range of the direction sensor 10, and the direction sensor 10 has no induction; when the small end face of the pipe clamp with different diameters faces the direction sensor 10, the non-empty area of the small end face of the pipe clamp with different diameters enters the induction range of the direction sensor 10, and the direction sensor 10 has induction. After the above structure is adopted, when the pipe clamp with different diameters is transported to the end of the material conveying track 9 and enters the rotating seat 21, the direction sensor 10 can identify the direction of the pipe clamp with different diameters; when the small end face of the pipe clamp with different diameters faces the direction sensor 10, the direction sensor 10 has signal output, then the adjusting cylinder 20 is extended to push the rotating cylinder 18, the rotating seat 21 and the pipe clamp with different diameters in the rotating seat 21 to move in the direction of the overturning feeding unit 3; the rotating cylinder 18 does not work, and the direction of the pipe clamp with different diameters does not need to be adjusted; the adjusting cylinder 20 continues to be extended to push the rotating cylinder 18, the rotating seat 21 and the pipe clamp with different diameters in the rotating seat 21 to the feeding inlet of the overturning feeding unit 3; when the large end face of the pipe clamp with different diameters faces the direction sensor 10, the direction sensor 10 has no signal output, then the adjusting cylinder 20 is extended to push the rotating cylinder 18, the rotating seat 21 and the pipe clamp with different diameters in the rotating seat 21 to move in the direction of the overturning feeding unit 3; the rotating cylinder 18 works and rotates by 180 degrees to adjust the direction of the pipe clamp with different diameters; the adjusting cylinder 20 continues to be extended to push the rotating cylinder 18, the rotating seat 21 and the pipe clamp with different diameters in the rotating seat 21 to the feeding inlet of the overturning feeding unit 3. After the above process, after the pipe clamp with different diameters is taken away by the overturning feeding unit 3, then the adjusting cylinder 20 is retracted, the rotating cylinder 18 and the rotating seat 21 are pulled back to the end of the material conveying track 9 by the adjusting cylinder 20; and the rotating seat 21 is opposite to the end of the material conveying track 9.

[0036] The sliding assembly in the device can also be a concave chute; the inner wall of the concave chute cooperates with the cylinder body of the rotary air cylinder (18), the concave chute is installed on the fixed frame, one end of which is located at the end of the material conveying track (9), and the other end is located at the inlet of the turnover feeding unit (3). In this way, the movement of the cylinder body of the rotary air cylinder (18) between the material conveying track (9) and the inlet of the turnover feeding unit (3) can also be realized.

[0037] Referring to Figure 1 、 Figure 2 and Figure 3 , the turnover feeding unit 3 in the device includes a clamping mechanism, a driving mechanism and a rotary fixed plate 14. The rotary fixed plate 14 is fixed on the fixed frame and located behind the end of the sliding rail 19; the side of the rotary fixed plate 14 facing the direction of the chute is rotationally connected with the clamping mechanism through a rotary shaft 13; the clamping mechanism includes a clamping air cylinder 15 and a clamping jaw 12; the rear end of the clamping air cylinder 15 is rotationally connected with the rotary fixed plate 14 through the rotary shaft 13; the clamping jaw 12 is fixed on the output end of the clamping air cylinder 15. The driving air cylinder 16 is two, both are piston rod type air cylinders, which are respectively arranged on the two sides of the clamping mechanism and rotationally connected with the fixed frame; the cylinder rods of the two driving air cylinders 16 are respectively rotationally connected with the side edges of the clamping mechanism, and the driving air cylinder 16 can drive the clamping mechanism to rotate with the rotary connection point of the clamping mechanism and the rotary fixed plate 14 as the rotation center. When the driving air cylinder 16 is not extended, the clamping jaw 12 is flush with the rotary seat 21, and the two clamping jaw arms of the clamping jaw 12 are respectively located on the two sides of the opening at the two ends of the rotary seat 21; when the driving air cylinder 16 is fully extended, the clamping jaw 12 is located above the inlet of the piece feeding chute. After adopting the above structure, when the rotary seat 21 is pushed into the inside of the clamping jaw 12 by the adjusting cylinder 20, the clamping air cylinder 15 works to control the clamping jaw 12 to clamp the reducing pipe joint; the driving air cylinder 16 is extended to make the clamping air cylinder 15 and the clamping jaw 12 turn over to the inlet of the piece feeding chute; when the clamping jaw 12 reaches above the inlet of the piece feeding chute, the clamping air cylinder 15 controls the clamping jaw 12 to release, and the reducing pipe joint falls into the piece feeding chute. Then the driving air cylinder 16 is retracted, the clamping mechanism falls down until the clamping jaw 12 is flush with the rotary seat 21, and the clamping jaw 12 falls into the opening at the two ends of the rotary seat 21.

[0038] The driving air cylinder 16 in the turnover feeding mechanism in the device can also be a rotary air cylinder, which is arranged between the adjusting unit and the piece feeding chute and is fixed on the fixed frame; the driving air cylinder 16 is fixedly connected with the clamping mechanism through a connecting rod; the rotation of the driving air cylinder 16 can drive the connecting rod and the clamping mechanism to rotate between the adjusting unit and the inlet of the piece feeding chute. In this way, in use, the clamping jaw 12 and the clamping air cylinder 15 are rotated from the rotary seat 21 to the inlet of the piece feeding chute through the rotation of the driving air cylinder 16.

[0039] The detection control unit in the device comprises a control chip, a conveying-to-position sensor 11 and a fullness sensor; the conveying-to-position sensor 11 is installed on one side of the end of the material conveying track 9; the fullness sensor is installed at the entrance of the piece chute; the conveying-to-position sensor 11 and the fullness sensor are both optical fiber sensing sensors, which can detect whether there is a pipe clamp passing through. The input end of the control chip is connected with the conveying-to-position sensor 11, the fullness sensor and the direction recognition assembly respectively, and the output end is connected with the lifting cylinder 7, the vibrating feeder, the rotating cylinder 18, the adjusting cylinder 20, the clamping cylinder 15 and the driving cylinder 16. With the above structure, when the fullness sensor detects that there is no pipe clamp on the piece chute, a signal is sent to the control chip, and then the control chip controls the clamping cylinder 15 and the driving cylinder 16 to work, so as to take the pipe clamp off the rotating seat 21 and send it to the piece chute. When the conveying-to-position sensor 11 detects that there is no pipe clamp at the end of the material conveying track 9, a signal is sent to the control chip, and then the control chip controls the lifting cylinder 7 to work, so as to lift the pipe clamp to the material conveying track 9; the control chip controls the vibrating feeder to work, so as to transport the pipe clamp on the material conveying track 9. When the conveying-to-position sensor 11 detects that there is a pipe clamp at the end of the material conveying track 9, a signal is sent to the control chip, and then the control chip judges whether the orientation of the pipe clamp is correct according to the signal of the direction sensor 10 at this time; if the orientation of the pipe clamp is correct, the control chip controls the rotating cylinder 18 not to work and controls the adjusting cylinder 20 to work, so as to send the pipe clamp to the entrance of the turnover feeding unit 3; if the orientation of the pipe clamp is incorrect, the control chip controls the rotating cylinder 18 to work, adjusts the orientation of the pipe clamp to be correct, and then controls the adjusting cylinder 20 to work, so as to send the pipe clamp to the entrance of the turnover feeding unit 3.

[0040] The working process of the device is as follows: the hopper 1 with the bottom surface inclined design makes the pipe clamp automatically slide to the last end, so that the pipe clamp slides above the front end of the stepped material feeding moving plate 5.

[0041] (A) When the delivery to position sensor 11 detects that the end of the material conveying track 9 is not a pipe collar, a signal is sent to the control chip, and the control chip controls the lifting cylinder 7 to drive the stepped material loading moving plate 5 to rise. At this time, the frontmost stepped material loading moving plate 5 drives the pipe collar on it to rise to the height of the frontmost stepped material loading stationary plate 6 and falls from the frontmost stepped material loading moving plate 5 to the frontmost stepped material loading stationary plate 6. The lifting cylinder 7 drives the stepped material loading moving plate 5 to descend. When the stepped material loading moving plate 5 behind the frontmost stepped material loading stationary plate 6 descends to the height of the frontmost stepped material loading stationary plate 6, the pipe collar on the frontmost stepped material loading stationary plate 6 falls onto the stepped material loading moving plate 5 behind it, and then rises to the stepped material loading stationary plate 6 behind it under the drive of the stepped material loading moving plate 5, thereby lifting the pipe collar step by step. The pipe collar on the last stepped material loading stationary plate 6 of the stepped material loading device rolls onto the material conveying track 9. The control chip controls the vibrating feeder to vibrate and drive the pipe collar to transport on the material conveying track 9. The limiting plate is parallel to the material conveying track 9 to prevent the pipe collar from falling outside the material conveying track 9.

[0042] (B) When the delivery to position sensor 11 detects that the end of the material conveying track 9 has a reduced pipe collar on the rotating seat 21, a signal is sent to the control chip. The control chip determines whether the orientation of the reduced pipe collar is correct according to the signal of the direction sensor 10 at this time. When the small end face of the reduced pipe collar faces the direction sensor 10, the direction sensor 10 has a signal output, and the reduced pipe collar enters the rotating seat 21. The control chip controls the rotating cylinder 18 to be inoperative, and controls the adjusting cylinder 20 to extend to push the rotating cylinder 18, the rotating seat 21 and the reduced pipe collar in the rotating seat 21 to the turnover feeding unit 3. When the large end face of the reduced pipe collar faces the direction sensor 10, the direction sensor 10 has no signal output, and the reduced pipe collar enters the rotating seat 21. The control chip controls the rotating cylinder 18 to work and rotate 180 degrees to adjust the orientation of the reduced pipe collar. Then, the control chip controls the adjusting cylinder 20 to extend to push the rotating cylinder 18, the rotating seat 21 and the reduced pipe collar in the rotating seat 21 to the turnover feeding unit 3. After the above process, the adjusting cylinder 20 is retracted, and the rotating cylinder 18 and the rotating seat 21 are pulled back to the end of the material conveying track 9 by the adjusting cylinder 20.

[0043] (C) When the full material sensor detects that there is no reduced pipe collar on the upper piece chute, a signal is sent to the control chip. The control chip controls the clamping cylinder 15 to work to control the clamping jaw 12 to clamp the reduced pipe collar on the rotating seat 21. The driving cylinder 16 extends to make the clamping mechanism turn over to the side of the rotating fixed plate 14 where the clamping mechanism is not fixed. When the clamping mechanism reaches above the upper piece chute, the control chip controls the clamping cylinder 15 to control the clamping jaw 12 to release, and the reduced pipe collar falls into the upper piece chute. Then the driving cylinder 16 retracts, and the clamping mechanism falls until the clamping jaw 12 is flush with the rotating seat 21.
