A blanking frame 9 for receiving and supporting the incoming work table 2

From the above, along the first direction (perpendicular to the axial direction of the pipe), the stations are arranged at intervals, and the stations from the side close to the feeding frame to the side close to the discharging frame 9 are the 1 st station, the 2 nd station, the 3 rd station and the … … nth station in sequence.

The working process of the invention is as follows: the first step: the pipe is manually carried or placed on the two feeding tables 1 in a lifting mode of equipment and the like, two ends of the pipe are respectively supported on the first turning plate 1111, the first turning plate 1111 can perform a preliminary adjustment function on the position of the pipe due to the V-shaped arrangement of the first turning plate 1111, the two ends of the pipe are positioned in the V-shaped of the first turning plate 1111 due to self weight of the pipe, the axial direction of the pipe is vertical to the first direction, and the pipe can be stably supported on the first turning plate 1111.

And a second step of: the control system controls the first cylinder 1112 to act, and the first cylinder 1112 rises to drive the first flap 1111 to rotate, and the first flap 1111 pushes the pipe located thereon to roll towards the adjustment zone 12. When the pipe rolls onto the supporting roller 121, the overhanging end of the second turning plate 1221 is lower than the plane of the feeding table 1, the rolling of the pipe is not blocked, the overhanging end of the third turning plate 1231 is higher than the plane of the feeding table 1, the pipe can be prevented from continuing to roll, and the pipe can stably stop on the supporting roller 121 due to the blocking effect of the third turning plate 1231 and the shape setting of the supporting roller 121, namely, the two ends of the pipe are respectively supported on the supporting rollers 121 of the two feeding tables 1, in particular, the pipe is simultaneously supported on the supporting roller 121, the second turning plate 1221 and the third turning plate 1231.

And a third step of: when the first position monitoring device 124 detects the pipe, the first position monitoring device 124 sends the detected information to the control system, the control system controls the motor 1211 to rotate after receiving the information of the first position monitoring device 124, the motor 1211 drives the riding wheel 121 to rotate sequentially through the reduction gearbox 1212 and the transmission chain 1213, the riding wheel 121 drives the pipe to move along the axial direction by virtue of friction between the riding wheel 121 and the pipe, and when the pipe moves to the second monitoring device 131 to monitor the pipe, the control system receives the information of the second monitoring device 131 and controls the motor 1211 to stop driving, and the pipe stops moving. At this time, the pipe is stopped at the set position in the pipe axial direction.

Fourth step: when the control system receives the information of the second monitoring device 131, the control system controls the third air cylinder 1232 to act, so that the third air cylinder 1232 drives the overhanging end of the third turning plate 1231 to descend so as not to block the rolling of the pipe, and simultaneously controls the second air cylinder 1222 to act, and the second air cylinder 1222 ascends to drive the second turning plate 1221 to rotate relative to the feeding table 1 and push the pipe positioned on the second turning plate to the working table 2. The rolling direction of the pipe is vertical to the axial direction of the pipe, so that the position of the pipe in the axial direction cannot be influenced after the pipe rolls.

At this time, the supporting component is at a preset feeding position. Due to the adjustment of the axial position of the pipe by the feeding frame, when the pipe enters the workbench 2, the pipe and the station are accurately aligned in the first linear direction (the axial direction of the pipe).

Fifth step: the pipe rolls, and passes through the 1 st station, the 2 nd station, the 3 rd station and the … … n-1 st station, at this time, the carrier roller 311 on the 1 st station, the 2 nd station, the 3 rd station and the … … n-1 st station is lower than the height of the limit supporting rod 51, the height of the highest point of the discharging rod 41 is not higher than the height of the limit supporting rod 51, the height of the highest point of the limit air cylinder 52 is lower than the height of the limit supporting rod 51, the transition supporting rod 532 is flush with the limit supporting rod 51, the carrier roller 311 on the n-th station is lower than the height of the limit supporting rod 51, and the height of the highest point of the limit air cylinder 52 is higher than the height of the limit supporting rod 51. At this time, the transition support rods 532 of the 1 st to n-1 st stations are attached to the pipe to pass over the V-shaped grooves 511, and when the pipe reaches the n-th station, the pipe stops rolling due to the presence of the V-shaped grooves 511 and the blocking of the limiting cylinder 52 and is supported in the V-shaped groove 511 of the n-th station.

Then, the second pipe is put on, the first step to the fifth step are repeated, and finally the second pipe falls into an n-1 station. At this time, the limit cylinder 52 of the n-1 station is raised so that the height of the highest point of the limit cylinder 52 of the station is higher than the height of the limit support rod 51, the transition support rod 532 is lowered so that the height of the transition support rod 532 of the station is lower than the lowest point of the V-shaped groove 511, and other stations remain unchanged.

Repeating the steps until all stations of the workbench 2 are full of pipe fittings.

Sixth step: when all stations of the workbench 2 are full of pipe fittings, the limiting cylinders 52 of all stations are lowered to perform a compounding process, and when compounding is performed, the carrier roller 311 is lifted to lift the pipe materials to leave the limiting support rods 51. The clamping device 61 then clamps the two ends of the tubing to be inflated. Then, the supporting body 21 runs along the track 232, so that the pipe gradually passes through the heating device 62 and the cooling device, and the plurality of carrier rollers 311 descend in sequence along the axial direction of the pipe in the process of passing through the heating device 62 and the cooling device, so as to avoid interference between the heating device 62 and the cooling device. Finally, the combination is completed, the clamping device 61 withdraws the clamping of the pipe, and the carrier roller 311 descends, so that the pipe is supported on the limit supporting rod 51 again.

Seventh, after the compounding is completed, the discharging air cylinder 42 is lifted to drive the discharging rod 41 to rotate relative to the supporting body 21, and the discharging rod 41 is inclined to push the plurality of pipes to roll onto the blanking frame 9 in sequence.

Since the pipe is automatically adjusted in the adjustment zone 12, it can enter the station on the table 2 accurately when it moves in the first direction, avoiding the risk of manual feeding of the pipe onto the table 2 and the interference with each other that would occur if the pipe were fed into the table 2 by the apparatus.

Finally, what is necessary here is: the above embodiments are only for further detailed description of the technical solutions of the present invention, and should not be construed as limiting the scope of the present invention, and some insubstantial modifications and adjustments made by those skilled in the art from the above description of the present invention are all within the scope of the present invention.
