The working principle of the utility model is as follows:

the feeding equipment 1 conveys the maca pipe fitting to the feeding area of the conveying belt 219, the maca pipe fitting conveyed to the conveying belt 219 is located in the feeding baffle 220, and the conveying belt 219 moves forwards to drive the maca pipe fitting in the feeding baffle 220 to move forwards, so that the maca pipe fitting output from the discharge hole of the feeding baffle 220 is guaranteed to be located on the same front-back straight line due to the limitation of the front left baffle 221 and the front right baffle 222 of the feeding baffle 220.

The marc steel pipe output from the feeding baffle 220 passes through the first rolling brush body 228, and the rolling frame body in rotation is contacted with the pipe keeping the standing posture to sweep the pipe down, so that the pipe is adjusted to the correct lying posture.

After passing through the first rolling brush body 228, the ma steel pipe fitting moves to a blanking area at the front end of the conveyor belt 219, when the martensi steel pipe fitting at the forefront passes between the pair of first opposite-injection switches 230, the first opposite-injection switches 230 detect the martensi steel pipe fitting, a detection signal is transmitted to the controller, and the controller controls the conveyor belt 219 to stop moving, and the martensi steel pipe fitting also stops moving forward. The light illuminates the blanking area of conveyer 219 front end, and the first industrial camera 209 just can carry out accurate discernment to the inside marmite pipe fitting of material loading area like this. After receiving the identification signal of the first industrial camera 209, the controller controls the mechanical arm of the first six-axis robot 205 to move to the position above the ma steel pipe fitting, and controls the two clamping arms 236 on the finger cylinder 235 to open to clamp the ma steel pipe fitting.

After the maca pipe fitting is clamped, the angle is switched, and the maca pipe fitting is placed between the movable top joint 218 and the fixed top joint, at this time, the driving cylinder 211 is in a contracted state, and the longitudinal guide rail 233 of the clamping mechanism 206 is kept in a front-back horizontal state. Then, a piston rod of the driving cylinder 211 stretches out to drive the rack 212 to move forwards, the rack 212 drives the gear 213 to rotate forwards, the gear 213 drives the swing rod 214 to swing forwards, the swing rod 214 drives the movable seat 216 to move forwards on the first guide rod 217 through the connecting rod 215, and accordingly the movable top joint 218 moves forwards, contacts with the macadam pipe fitting in the forward moving process of the movable top joint 218 and continuously drives the macadam pipe fitting to move forwards synchronously. In the process of advancing the maca pipe fitting, the finger cylinder 235 and the longitudinal sliding block 234 are driven to synchronously advance on the longitudinal guide rail 233, and at the moment, the return spring 238 is stretched. When the movable top sub 218 contacts the fixed top sub, the movement of the malleable cast is stopped, and the movable top sub 218 and the fixed top sub complete the fixation of the malleable cast, with the return spring 238 in tension.

Subsequently, the two clamping arms 236 on the finger cylinder 235 are controlled to be released, the clamping mechanism 206 is separated from the marc steel pipe fitting, and the threading machine 3 completes threading of the marc steel pipe fitting. When the clamping mechanism 206 is disengaged from the malleable cast iron pipe fitting, the finger cylinder 235 loses the external force and moves back under the action of the return spring 238 until it contacts the stop 237, so that the clamping mechanism 206 returns to its original state.

After the wire sleeving process of the maca pipe fitting is finished, the driving cylinder 211 is controlled to shrink, a piston rod of the driving cylinder 211 is retracted, the rack 212 is driven to move backwards, the rack 212 drives the gear 213 to rotate reversely, the gear 213 drives the swing rod 214 to swing backwards, the swing rod 214 drives the movable seat 216 to move backwards on the first guide rod 217 through the connecting rod 215, and accordingly the movable top joint 218 moves backwards, the movable top joint 218 is separated from the maca pipe fitting, the maca pipe fitting falls from the fixed top joint, and all wire sleeving processes are finished.

The above steps are repeated continuously, and the marc steel pipe pieces on the conveyor belt 219 are threaded one by one.

The maca steel pipe fitting after threading of the threading machine is input to the feed inlet of the primary lifting device 4, enters the lifting cage 403 of the primary lifting device through the feed inlet, and the first driving motor 405 drives the two rotating rods 406 to rotate simultaneously through the two sets of chain transmission mechanisms 409, and the two rotating rods 406 drive the lifting cylinder 403 to rotate simultaneously. Because the helical blades 404 inside the lifting cage 403 are in a helical structure, the macaroni pipe fitting at the lower end of the lifting cage 403 is continuously lifted under the rotation action of the helical blades 404, and finally is output outwards from the outlet at the upper end of the lifting cage 403.

After the threading process is finished, the pipe fitting needs to be subjected to a pressure detection process to detect whether the pipe wall of the pipe fitting has defects such as sand holes, if the pipe wall of the pipe fitting has the defects such as sand holes, the tightness of the pipe fitting cannot reach the standard, and the pipe fitting cannot be normally used.

The primary lifting device transfers the jacketed pipe to the rear end of the bi-directional conveyor 506, if the pipe falls to the rear end of the reverse conveyor 523, the pipe continues to move backward under the action of the reverse conveyor 523 until the pipe contacts the rear baffle 526, and the pipe on the reverse conveyor 523 is moved to the rear end of the forward conveyor 522 under the interaction of the reverse conveyor 523 and the rear baffle 526 and moves forward to the recognition area under the action of the forward conveyor 522. If the tubular falls directly from the transfer mechanism to the rear end of the forward conveyor 522, the tubular is moved forward to the identification zone directly by the forward conveyor 522

When the pipe moves forward under the action of the forward conveyor 522, the pipe passes through the second roller brush body 527, and the rotating roller frame contacts with the pipe which keeps the standing posture and sweeps the pipe down, so that the pipe is adjusted to the correct lying posture. While some tubes that remain in a "standing" position even under the influence of the second roller brush body 527. The pipe fitting that keeps "standing" gesture and "lying" gesture is all moved to the discernment region of front end like this under the effect of forward conveyer 522, and light 528 will discern the pipe fitting in the discernment region completely, and the accurate discernment of pipe fitting in the discernment region just can be carried out to the second industrial camera 507 like this. The tube still kept in the "standing" position at the recognition area is moved into the reverse conveyor belt 523 by the combined action of the forward conveyor belt 522 and the front side shutter 525, and is moved to the rear side by the reverse conveyor belt 523, and is again regulated while passing the second roller brush body 527; the pipe fitting on the reverse conveyor belt 523 is moved to the rear end of the forward conveyor belt 522 by the interaction of the reverse conveyor belt 523 and the rear baffle 526 until the pipe fitting comes into contact with the rear baffle 526 after passing through the second roller brush body 527, and is moved forward to the recognition area by the forward conveyor belt 522, passes through the second roller brush body 527 again while traveling on the forward conveyor belt 522, and then reaches the recognition area again. If the pipe is kept in the standing posture, the pipe is not grasped by the second six-axis robot 505 in the recognition area, and the pipe is continuously and circularly moved on the bidirectional conveyor belt 506 until being adjusted to the lying posture by the second rolling brush body 527, and finally grasped by the second six-axis robot 505.

When the second industrial camera 507 recognizes a pipe in the "lying" position, the gripper of the second six-axis robot 505 grips the pipe and places it on the press dies 513 of the first press-detecting assembly, and then returns to the recognition area again to grip the next pipe in the "lying" position and place it on the press dies 513 of the second press-detecting assembly … … in turn placing each pipe in the "lying" position on the press dies 513 of the six press-detecting assemblies.

When the pipe fitting is placed on the lower pressing die 513, the lower pressing cylinder 514 corresponding to the lower pressing die 513 starts to act to drive the upper pressing die 512 to descend, the upper pressing die 512 clamps the pipe fitting together with the lower pressing die 513, the upper pressing die 512 seals all openings of the pipe fitting together with the lower pressing die 513, the pipe fitting is in a sealed state, and meanwhile, the air inlet hole on the lower pressing die 513 is communicated with the inside of the pipe fitting. At this time, the pressure detecting valve is opened, compressed air is input into the pipe fitting through the pressure detecting pipe 519 by the air storage tank 529, so that the inside of the pipe fitting is at a set air pressure value, and the pressure value inside the pipe fitting is monitored through the digital display pressure switch 520. If the pipe has a defect such as sand hole, the air leakage phenomenon occurs, and the air pressure value inside the pipe is reduced and the set value cannot be maintained, so that the digital display pressure switch 520 monitors the change of the air pressure value inside the pipe and transmits a change signal to the pressure detection controller 509, the pressure detection controller 509 receives the change signal, controls the pressure detection valve to be closed, controls the lower pressure cylinder 514 to shrink and drive the upper pressure die 512 to rise to be separated from the pipe, then controls the push-out cylinder 515 corresponding to the lower pressure die 513 to extend, pushes out the defective pipe from the lower pressure die 513 and drops into the defective product output hopper 504 through the piston rod of the push-out cylinder 515, and finally outputs the defective product from the outlet of the defective product output hopper 504. If the pipe fitting has no defects such as sand holes, the inside of the pipe fitting will not leak, the air pressure value inside the pipe fitting will always be kept at the set value, the digital display pressure switch 520 detects that the air pressure value inside the pipe fitting has not changed within the set time period, the unchanged signal will be output to the pressure detection controller 509, the pressure detection controller 509 receives the unchanged signal, controls the pressure detection valve to close, controls the lower pressure cylinder 514 to shrink and drive the upper pressure die 512 to rise to separate from the pipe fitting, and then controls the second six-axis robot 505 to grasp the pipe fitting in the next 'lying' gesture and place the pipe fitting on the currently detected lower pressure die 513, so that the pipe fitting which has been detected on the lower pressure die 513 is ejected, the ejected qualified pipe fitting is output from the front side of the pressure detection window 502 and falls into the material placing groove.

Operators manually detect qualified ma steel pipe fittings with obvious flaws on one side of the material placing groove 6, send qualified ma steel pipe fittings without obvious flaws to the material inlet of the secondary lifting equipment 7, and soak the qualified ma steel pipe fittings in the oil agent in the shell of the secondary lifting equipment 7 to form a layer of oil film on the surface of the ma steel pipe fittings, thereby achieving the effects of corrosion resistance and rust resistance.

The secondary lifting device 7 lifts the maca steel pipe upwards and outputs the maca steel pipe to the rear side of the screen plate of the vibrating screen 8, the screen groove 801 and the screen plate 802 are driven to vibrate through the action of the vibrating motor 804, and the vibrating screen plate 802 moves the maca steel pipe forwards. During the forward movement of the malted steel pipe, the superfluous oil on the surface of the malted steel pipe flows down to the surface of the sieve plate 802 and flows into the sieve groove 801 below the sieve plate 802 through the sieve holes on the sieve plate 802. The oil inside the screen sump 801 eventually collects from the oil outlet on the sidewall. The marc steel pipe is finally output outwards from a discharge port at the front side of the vibrating screen 8 to the inside of a feeding hopper 905 of the conveying equipment 9.

The marc tubing inside the upper hopper 905 moves with the conveyor belt 904 and is conveyed outside the upper hopper 905 through a flare at the front end of the upper hopper 905. The marsteel pipe elements are blocked as they pass the flare so that the marsteel pipe elements pass the flare one by one so that the marsteel pipe elements move in a linear arrangement on the conveyor belt 904 towards the side of the blanking hopper 906.

When the marc steel pipe fitting passes through the second correlation switch, the second correlation switch detects the marc steel pipe fitting, so that the passing marc steel pipe fitting is counted, a counting signal is transmitted to the controller, and the controller records the total number of the marc steel pipe fitting passing through the second correlation switch.

The marc tubing passing through the second pair of shooting switches continues forward into the interior of the blanking hopper 906 and eventually builds up inside the blanking hopper 906.

The second driving motor 104 controls the rotating sleeve 103 to rotate, so that a group of fixed ferrules 107 and the fixed seat 108 rotate below the front end opening of the discharging hopper 906, a charging bag is placed on the fixed seat 108, and the upper end opening of the charging bag is sleeved on the outer side of the fixed ferrules 107.

When the second correlation switch detects that the number of the marc steel pipes passing through the second correlation switch reaches the bagging quantity, the piston rod of the control cylinder 910 stretches out, the piston rod drives the action rod 909 to rotate, the action rod 909 drives the rotation shaft 908 to rotate, and the rotation shaft 908 drives the baffle 907 to rotate, so that the front end outlet of the discharging hopper 906 is exposed, and all the marc steel pipes inside the discharging hopper 906 are filled into the charging bags. Then, the piston rod of the air cylinder 910 is retracted, the piston rod drives the action rod 909 to reversely rotate, the action rod 909 drives the rotating shaft rod 908 to reversely rotate, and the rotating shaft rod 908 drives the baffle 907 to reversely rotate, so that the front end outlet of the discharging hopper 906 is reclosed, the macadam pipe inside the discharging hopper 906 cannot be continuously output outwards, and the macadam pipe is piled again.

The second driving motor 104 controls the rotating sleeve 103 to rotate by a set angle, so that the next set of fixing rings 107 and the fixing seat 108 rotate below the front end opening of the discharging hopper 906, and the charging bags are fixed on the set of fixing rings 107 and the fixing seat 108, and the charging bags after being filled are packed and tidied.

The above process is repeated continuously so that the marc steel pipe on the conveyor belt 904 is continuously loaded into the loading bag.
