The top surfaces of the step feeding movable plate 5 and the step feeding static plate 6 are preferably designed to be inclined backwards. After the structure is adopted, the hopper 1 with the inclined bottom surface enables the pipe hoop to automatically slide to the rearmost end, and the pipe hoop slides above the stepped feeding movable plate 5 at the foremost end; the lifting cylinder 7 drives the step feeding movable plate 5 to ascend, and at the moment, the foremost step feeding movable plate 5 drives the pipe hoop to ascend to the foremost step feeding static plate 6 and slide down from the foremost step feeding movable plate 5 to the foremost step feeding static plate 6; the lifting cylinder 7 drives the step feeding movable plate 5 to descend, when the step feeding movable plate 5 behind the foremost step feeding static plate 6 descends to the height of the foremost step feeding static plate 6, the pipe hoop on the foremost step feeding static plate 6 slides onto the step feeding movable plate 5 behind the foremost step feeding static plate, and then the pipe hoop is driven by the step feeding movable plate 5 to ascend onto the following step feeding static plate 6, so that the pipe hoop is lifted up step by step. Because the top surfaces of the step feeding static plate 6 and the step feeding movable plate 5 are strip-shaped surfaces, the posture of the pipe clamp can be automatically adjusted in the lifting process.

Referring to fig. 1 and 2, the conveying unit 4 of the present invention includes a conveying rail 9 and a vibrating feeder; the conveying track 9 is a U-shaped strip track and is arranged at the rear end of the step feeding device, and the U-shaped conveying track 9 ensures that the posture of the pipe hoop is unchanged when the pipe hoop is transported on the conveying track.

The height of the material conveying track 9 is not higher than the height of the top surface of the rearmost stepped material feeding static plate 6. After the structure is adopted, the pipe hoop conveyed to the rearmost step feeding static plate 6 by the step feeding device falls onto the material conveying track 9 in a rolling manner; due to the adjustment of the posture of the pipe hoop in the lifting process, the pipe hoop is orderly and directionally arranged on the material conveying track 9; the vibration feeder vibrates to drive the pipe hoop to be transported on the material conveying track 9.

The rotary cylinder 18 is fixedly connected with the cylinder rods of the slide block 17 and the adjusting cylinder 20 respectively; thus, the adjusting cylinder 20 can push and pull the rotating cylinder 18 by telescoping to realize the sliding of the rotating cylinder 18 and the slide block 17 on the slide rail 19, so as to realize the reciprocating movement of the rotating cylinder 18 between the end of the feeding track 9 and the feeding port of the turnover feeding unit 3. The rotary seat 21 is also of a U-shaped strip structure, and the bottom of the rotary seat is flush with the bottom of the material conveying track 9; the U-shaped two ends and the upper part of the rotating seat 21 are opened, so that the pipe clamp can enter and exit; the output end of the rotary cylinder 18 extends upwards and is connected with the arc-shaped bottom of the rotary seat 21. The large end face and the small end face of the pipe hoop can be reversed through the rotation of the rotary cylinder 18 in the adjusting unit. When the adjusting cylinder 20 does not extend out, the rotating base 21 is located at the tail end of the material conveying rail 9, and openings at two ends of the rotating base 21 are along the material conveying direction of the material conveying rail 9; since the feeding track 9 is also U-shaped, the pipe clamp can enter from the openings at the two ends of the rotary seat 21 without changing the orientation of the pipe clamp.

The adjusting unit also comprises a direction identifying component; the direction recognition component comprises a direction sensor 10 and a sensing baffle 22; the direction sensor 10 is fixed at the tail end of the conveying track 9 and at the rear part of the rotary seat 21 when the adjusting cylinder 20 does not extend out, the direction sensor 10 is arranged right at the large end face or the small end face of the reducing pipe hoop on the conveying track 9, the direction sensor 10 is a proximity switch type sensor, the distance from the direction sensor 10 to the large end face non-empty area of the reducing pipe hoop is greater than the sensing distance of the direction sensor 10, and the distance from the direction sensor 10 to the small end face non-empty area of the reducing pipe hoop is less than the sensing distance of the direction sensor 10. The sensing baffle 22 is made of an insulating material and is sleeved outside the direction sensor 10 to isolate interference of other factors. Thus, when the large end face of the reducing pipe clamp faces the direction sensor 10, the non-empty area of the large end face of the reducing pipe clamp cannot enter the sensing range of the direction sensor 10, and the direction sensor 10 has no sensing; when the small end face of the reducing pipe clamp faces the direction sensor 10, the non-empty area of the small end face of the reducing pipe clamp enters the sensing range of the direction sensor 10, and the direction sensor 10 senses the small end face of the reducing pipe clamp. After the structure is adopted, when the reducing pipe hoop is transported to the tail end of the material conveying track 9 and enters the rotating seat 21, the direction sensor 10 can identify the orientation of the reducing pipe hoop; when the small end face of the reducing pipe hoop faces the direction sensor 10, the direction sensor 10 outputs signals, and then the adjusting cylinder 20 extends out to push the rotating cylinder 18, the rotating seat 21 and the reducing pipe hoop in the rotating seat 21 to move towards the overturning and feeding unit 3; the rotary cylinder 18 does not work, and the orientation of the reducing pipe hoop does not need to be adjusted; the adjusting cylinder 20 continuously extends out, and the rotating cylinder 18, the rotating seat 21 and the reducing pipe hoop in the rotating seat 21 are pushed to a feeding port of the turnover feeding unit 3; when the large end face of the reducing pipe hoop faces the direction sensor 10, the direction sensor 10 outputs no signal, and then the adjusting cylinder 20 extends out to push the rotating cylinder 18, the rotating seat 21 and the reducing pipe hoop in the rotating seat 21 to move towards the overturning and feeding unit 3; the rotary cylinder 18 works, rotates by 180 degrees, and adjusts the orientation of the reducing pipe hoop; the adjusting cylinder 20 continues to extend out, and the rotating cylinder 18, the rotating base 21 and the reducing pipe hoop in the rotating base 21 are pushed to a feeding port of the turnover feeding unit 3. After the above process, after the reducing pipe hoop is taken away by the overturning and feeding unit 3, the adjusting cylinder 20 retracts, and the rotary cylinder 18 and the rotary seat 21 are pulled back to the tail end of the conveying track 9 by the adjusting cylinder 20; the rotary seat 21 is opposite to the tail end of the material conveying track 9.

Referring to fig. 1, 2 and 3, the reverse feeding unit 3 of the present invention includes a clamping mechanism, a driving mechanism and a rotation fixing plate 14. The rotary fixing plate 14 is fixed on the fixing frame and is positioned behind the tail end of the sliding rail 19; one side of the rotary fixing plate 14 facing the direction of the slide way is rotatably connected with a clamping mechanism through a rotating shaft 13; the clamping mechanism comprises a clamping cylinder 15 and a clamping jaw 12; the rear end of the clamping cylinder 15 is rotatably connected with the rotary fixing plate 14 through a rotating shaft 13; the clamping jaw 12 is fixed at the output end of the clamping cylinder 15. The two driving cylinders 16 are piston rod type cylinders, are respectively arranged on two sides of the clamping mechanism and are rotatably connected to the fixing frame, the cylinder rods of the two driving cylinders 16 are respectively rotatably connected with the side edges of the clamping mechanism, and the driving cylinders 16 can drive the clamping mechanism to rotate by taking the rotating connection point of the clamping mechanism and the rotating fixing plate 14 as a rotating center through extension and retraction. When the driving cylinder 16 is not extended out, the clamping jaw 12 is flush with the rotating base 21, and two clamping jaw arms of the clamping jaw 12 are respectively positioned at two sides of openings at two ends of the rotating base 21; when the driving air cylinder 16 is fully extended, the clamping jaw 12 is positioned above the feeding port of the upper scraper-trough conveyer. After the structure is adopted, when the rotating base 21 is pushed into the clamping jaw 12 by the adjusting cylinder 20, the clamping cylinder 15 works to control the clamping jaw 12 to clamp the reducing pipe hoop; the driving air cylinder 16 extends out, so that the clamping air cylinder 15 and the clamping jaw 12 turn over towards the feeding port of the upper scraper-trough conveyer; when the clamping jaw 12 reaches the upper part of the feeding port of the upper part slide, the clamping cylinder 15 controls the clamping jaw 12 to loosen, and the reducing pipe hoop falls into the upper part slide. Then the cylinder 16 is driven to retract, and the clamping mechanism falls until the clamping jaws 12 are flush with the rotary base 21, and the clamping jaws 12 fall on the openings at the two ends of the rotary base 21.

The driving cylinder 16 in the turnover feeding mechanism can also be a rotary cylinder which is arranged between the adjusting unit and the upper slide and is fixed on the fixed frame, the driving cylinder 16 is fixedly connected with the clamping mechanism through a connecting rod, and the rotation of the driving cylinder 16 can drive the connecting rod and the clamping mechanism to rotate between the adjusting unit and the inlet of the upper slide. Thus, in use, the gripper jaws 12 and the gripper cylinders 15 are rotated from the rotary base 21 to the upper slide inlet by the rotation of the drive cylinders 16.

The detection control unit comprises a control chip, a delivery in-place sensor 11 and a full-material sensor; the delivery in-place sensor 11 is arranged on one side of the tail end of the delivery track 9; the full material sensor is arranged at an inlet of the upper part scraper-trough conveyer; the delivery in-place sensor 11 and the full-material sensor are both optical fiber sensing sensors, and can detect whether the reducing pipe hoop passes through or not.

By adopting the structure, when the full-material sensor detects that no reducing pipe hoop exists on the upper slide carriage, 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 that the reducing pipe hoop is taken down from the rotating seat 21 and is sent to the upper slide carriage. When the in-place conveying sensor 11 detects that the tail end of the conveying track 9 is not provided with the reducing pipe hoop, a signal is sent to the control chip, the control chip controls the lifting cylinder 7 to work, and the reducing pipe hoop is lifted to the conveying track 9; and the control chip controls the vibration feeder to work, so that the reducing pipe hoop is transported on the material conveying track 9. When the in-place conveying sensor 11 detects that the tail end of the conveying track 9 is provided with the reducing pipe hoop, a signal is sent to the control chip, and the control chip judges whether the orientation of the reducing pipe hoop is correct or not according to the signal of the direction sensor 10; if the orientation of the reducing pipe hoop is correct, the control chip controls the rotary cylinder 18 not to work, the adjusting cylinder 20 works, and the reducing pipe hoop is sent to a feeding position of the overturning and feeding unit 3; if the orientation of the reducing pipe hoop is incorrect, the control chip controls the rotary cylinder 18 to work, the orientation of the reducing pipe hoop is adjusted to be correct, then the control chip controls the adjusting cylinder 20 to work, and the reducing pipe hoop is sent to a feeding position of the overturning and feeding unit 3.
