[0036] A plurality of top horizontal chain conveyor belts 3 are hoisted on the top of the overall frame 1. In this embodiment, three top horizontal chain conveyor belts 3 are provided. The vertical top horizontal chain conveyor belts 3 are hoisted on the overall frame 1 by bolts. Each top horizontal chain conveyor belt 3 is driven by a second motor to run synchronously.

Vertical push plates 7 are arranged at equal intervals on each top horizontal chain conveyor belt 3. When the plastic pipe 17 is lifted to the top, the plastic pipe 17 can be pushed to move horizontally as the chain rotates through the vertical push plates 7.

[0038] A plurality of bottom horizontal chain conveyor belts 4 are provided at the bottom of the overall frame 1. In the present embodiment, three bottom horizontal chain conveyor belts 4 are provided for receiving the plastic pipes 17 dropped from the plastic pipe bin 8 at the bottom layer. The bottom horizontal chain conveyor belts 4 are connected to the overall frame 1 by bolts. Each bottom horizontal chain conveyor belt 4 is driven by a third motor to run synchronously. The output end of the bottom horizontal chain conveyor belt 4 extends to the outside of the overall frame 1. A plurality of second push plates 10 are arranged at intervals on the bottom horizontal chain conveyor belt 4 for pushing the plastic pipes 17 to the next process.

[0039] In this embodiment, a first position sensor is provided at a position corresponding to the top of the overall frame 1 and the vertical chain conveyor belt 2, for sensing whether the plastic pipe 17 is lifted to the top.

[0040] In this embodiment, a second position sensor is provided at a corresponding position between the overall frame 1 and the flap 9 at the upper end of each plastic pipe bin 8 on the uppermost layer, for sensing whether there are plastic pipes 17 above each plastic pipe bin 8 on the uppermost layer.

[0041] In this embodiment, a third position sensor is provided at a corresponding position between the overall frame 1 and each plastic pipe bin 8 at the bottom layer, for sensing whether there are plastic pipes 17 in each plastic pipe bin 8 at the bottom layer.

[0042] In this embodiment, the linkage mechanism includes a cylinder 11, a push rod 12, a connecting rod mechanism 13 and a flap shaft 14; in each flap 9 on the same layer, one end of the flap 9 in the same plastic tube bin 8 is fixed on the flap shaft 14, and each flap shaft 14 is connected to the push rod 12 through a connecting rod mechanism 13. The push rod 12 is slidably arranged on the overall frame 1 and connected to the telescopic end of the cylinder 11. The push rod 12 is pushed to move by the telescopic movement of the cylinder 11. The movement of the push rod 12 drives the rotation of each flap shaft 14 through each connecting rod mechanism 13, thereby realizing the synchronous flipping of each flap 9.

[0043] In this embodiment, the top rotating shafts of each vertical chain conveyor belt 2 are connected to each other through a coupling, and the output end of the first motor is connected to the top rotating shaft of one of the vertical chain conveyor belts 2. The first motor drives the four vertical chain conveyor belts 2 to operate synchronously to lift the plastic pipe 17.

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

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

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

[0047] When the plastic pipe 17 climbs to the top with the rotation of the vertical chain conveyor belt 2, it is monitored by the first position sensor. At this time, the vertical chain conveyor belt 2 stops rotating, and the plastic pipe 17 flips to the bottom of the top horizontal chain conveyor belt 3 under the guidance of the inclined guide plate. The top horizontal chain conveyor belt 3 rotates, and the vertical push plate 7 installed on the top horizontal chain conveyor belt 3 will push the plastic pipe 17 to move. In this process, the plastic pipe 17 is supported by the flap 9 on the top of the storage bin 5 and is monitored by the second position sensor. After that, the vertical chain conveyor belt 2 continues to transport the plastic pipe 17 to the top and is pushed to move by the top horizontal chain conveyor belt 3 again; with the interval operation of the vertical chain conveyor belt 2 and the top water The flat chain conveyor belt 3 operates at intervals to continuously fill the space above the storage bin 5 with the plastic tube 17; when the plastic tube 17 fills the space above the storage bin 5, the top horizontal chain conveyor belt 3 and the vertical chain conveyor belt 2 stop rotating, and except for the cylinder 11 at the bottom layer, the cylinders at other different layers operate successively from top to bottom, so that the plastic tube 17 falls to the bottom layer of the storage bin 5; wherein, the falling of the plastic tube 17 is achieved in the following manner: the cylinder 11 contracts, pulling the push rod 12 to move backward, and the push rod 12 drives the connecting rod mechanism 13 to make the flap 9 rotate around the flap shaft 14, so that the plastic tube 17 on the flap 9 falls into the plastic tube bin 8 of the storage bin 5, and then the cylinder 11 drives the flap 9 to reset.

[0048] Continue to repeat the above steps, through the cooperation of the vertical chain conveyor belt 2 and the top horizontal chain conveyor belt 3, under the sequential action of the corresponding layers of cylinders 11, the plastic pipes 17 fill the storage bin 5 layer by layer from bottom to top, thereby achieving the purpose of storing the plastic pipes 17.

[0049] When the pipe threading process requires plastic pipe 17, the cylinder 11 at the bottom layer is actuated, and the push rod 12 drives the connecting rod mechanism 13 to rotate the flap 9 around the flap shaft 14, and the plastic pipe 17 at the bottom layer 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 as the chain rotates, and finally realize the transportation of the plastic pipe 17 from the storage bin to the next process (plastic pipe passing 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 on this layer, the cylinders 11 of each layer except the bottom layer will start to move in turn, so that the plastic pipe 17 of each layer in the storage bin 5 is passed downward in turn; and then through the cooperation of the vertical chain conveyor 2 and the top horizontal chain conveyor 3, the storage bin 5 is filled again under the sequential action of the cylinders 11 of each layer.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
