Each flap 9 in the same layer is connected by a linkage mechanism. The linkage mechanism drives each flap 9 in the same layer to flip synchronously so that the plastic pipes 17 on the flaps 9 fall to the next layer.

[0039] In this embodiment, a first position sensor is arranged at the corresponding position of the top of the vertical chain conveyor 2 and the overall frame 1 to sense whether the plastic pipes 17 are lifted to the top.

[0040] In this embodiment, a second position sensor is arranged at the corresponding position of the flaps 9 at the upper end of each plastic pipe bin 8 in the uppermost layer and the overall frame 1 to sense whether there are plastic pipes 17 above each plastic pipe bin 8 in the uppermost layer.

[0041] In this embodiment, the third position sensor is arranged at the corresponding position of the overall frame 1 and the lowermost plastic pipe bin 8, and is used to detect whether the plastic pipe 17 is in the lowermost plastic pipe bin 8.

[0042] In this embodiment, the linkage mechanism includes the cylinder 11, the push rod 12, the linkage mechanism 13, and the flap shaft 14.

[0043] In this embodiment, the top end rotating shafts of the vertical chain conveyors 2 are connected through the shaft coupling, and the output end of the first motor is drivingly connected to the top end rotating shaft of one of the vertical chain conveyors 2. The four vertical chain conveyors 2 are driven to rotate synchronously by the first motor, and the plastic pipe 17 is lifted.

[0044] In this embodiment, the rotating shaft of the end of the top horizontal chain conveyor 3 away from the vertical chain conveyor 2 is the driving shaft, the driving shafts of the top horizontal chain conveyors 3 are connected through the shaft coupling, and the output end of the second motor is drivingly connected to the driving shaft of one of the top horizontal chain conveyors 3. The three top horizontal chain conveyors 3 are driven to rotate synchronously by the second motor, and the plastic pipe 17 is horizontally pushed.

[0045] In this embodiment, the rotating shaft of the output end of the bottom horizontal chain conveyor 4 is the driving shaft, the driving shafts of the bottom horizontal chain conveyors 4 are connected through the shaft coupling, and the output end of the third motor is drivingly connected to the driving shaft of one of the bottom horizontal chain conveyors 4. The three bottom horizontal chain conveyors 4 are driven to rotate synchronously by the third motor, and the plastic pipe 17 is horizontally conveyed to the next process.

[0046] In this embodiment, the linkage mechanism 13 includes the first linkage 15 and the second linkage 16, one end of the first linkage 15 is fixed to the flap shaft 14, the other end is rotatably connected to one end of the second linkage 16, and the other end of the second linkage 16 is rotatably connected to the push rod 12.

[0047] When the plastic pipe 17 climbs to the top of the vertical chain conveyor 2 and is monitored by the first position sensor, the vertical chain conveyor 2 stops rotating, and the plastic pipe 17 is flipped under the top horizontal chain conveyor 3 by the guide of the inclined guide plate, the top horizontal chain conveyor 3 rotates, and the vertical push plate 7 installed on the top horizontal chain conveyor 3 pushes the plastic pipe 17 to move, and the process is supported by the flap 9 at the top of the storage bin 5, which is monitored by the second position sensor, then the vertical chain conveyor 2 continues to transport the plastic pipe 17 to the top and is pushed to move by the top horizontal chain conveyor 3 again; with the interval operation of the vertical chain conveyor 2 cooperating with the interval operation of the top horizontal chain conveyor 3, the plastic pipe 17 continuously fills the space above the storage bin 5; when the plastic pipe 17 fills the space above the storage bin 5, the top horizontal chain conveyor 3 and the vertical chain conveyor 2 stop rotating, and the cylinders of different layers act from top to bottom in turn except the bottommost cylinder 11, so that the plastic pipe 17 falls to the bottom layer of the storage bin 5; wherein the falling of the plastic pipe 17 is realized as follows: the cylinder 11 retracts, pulls the push rod 12 to move backward, the push rod 12 drives the connecting rod mechanism 13 to rotate the flap 9 around the flap shaft 14, so that the plastic pipe 17 on the flap 9 falls into the plastic pipe bin 8 of the storage bin 5, and then the cylinder 11 drives the flap 9 to reset.

[0048] The above steps are continuously repeated, and the plastic pipe 17 is filled in the storage bin 5 layer by layer from bottom to top by the cooperation of the vertical chain conveyor 2 and the top horizontal chain conveyor 3 under the action of the corresponding cylinders 11, so as to achieve the purpose of storing the plastic pipe 17.

[0049] When the plastic pipe 17 is needed in the pipe threading process, the bottommost cylinder 11 acts, the push rod 12 drives the connecting rod mechanism 13 to rotate the flap 9 around the flap shaft 14, and the bottommost plastic pipe 17 falls on the bottom horizontal chain conveyor 4, the second push plate 10 installed on the bottom horizontal chain conveyor 4 can push the plastic pipe 17 to move with the rotation of the chain, and finally realize the transportation of the plastic pipe 17 from the storage bin to the next process (threading the plastic pipe into the steel pipe); when the third position sensor at the bottom layer of the storage bin 5 detects that there is no plastic pipe 17 in this layer, each cylinder 11 except the bottom cylinder 11 will act in turn, so that the plastic pipe 17 in each layer of the storage bin 5 is transferred downward in turn; then the storage bin 5 is filled again by the cooperation of the vertical chain conveyor 2 and the top horizontal chain conveyor 3 under the action of the corresponding cylinders 11.

[0050] The principles and implementation manners of the present application are described by using specific examples in the present application, and the above examples are only used for helping to understand the method of the present application and its core idea; meanwhile, for the general technical personnel in the art, according to the idea of the present application, the specific implementation manners and application ranges will be changed. In conclusion, the content of the present specification should not be understood as the limitation of the present application.
