Description

Technical Field

[0001] The present invention relates to the technical field of pipe feeding mechanisms, and more particularly, to a special-shaped pipe feeding and conveying mechanism. Background Art

[0002] The IBC frame is a frame structure suitable for supporting and fixing IBC tanks. The IBC frame consists of a chassis and a frame body. The frame body is welded by steel pipes, and the chassis is made of galvanized thin steel plates with rounded corners. The frame body is used to prevent the IBC tank from being damaged by external impacts, so the frame body needs to have high structural strength. Currently, the frame body is mainly divided into a round pipe type frame and a square pipe type frame. The round pipe type frame is a frame made of round steel pipes, and the square pipe type frame is a frame made of square steel pipes.

[0003] Furthermore, the special-shaped pipe is a component used for welding and fixing at the upper end of the above-mentioned frame body. The special-shaped pipe includes a circular pipe body and a convex edge provided on the outer wall of the pipe body and extending outward in the radial direction of the pipe body. Currently, before welding the special-shaped pipe to the frame body in the IBC frame, the special-shaped pipe is manually oriented and manually placed at the material taking station of the welding machine, resulting in the disadvantages of low feeding efficiency of the special-shaped pipe and high labor cost.

[0004] Therefore, the current Chinese Patent Publication No.: CN215827805 discloses a pipe feeding device. The pipe feeding device can change the inclination angle of the material receiving frame, so that the pipe feeding device can be suitable for feeding various pipes including special-shaped pipes. When in use, only by adjusting the height adjustment mechanism according to the movement of the pipe on the support structure, the pipe can be smoothly transported, improving the adaptability of the pipe feeding device.

[0005] However, in the above pipe feeding device structure, although it can realize the feeding of special-shaped pipes, it is difficult to adjust and determine the orientation of the special-shaped pipes after the feeding of the special-shaped pipes. That is, when the pipe feeding device supplies the special-shaped pipe outward, the discharging orientation of the special-shaped pipe is uncertain, making it difficult to meet the welding requirements of the special-shaped pipe and the frame body in the IBC frame by the welding machine. Summary of the Invention

The special-shaped pipe comprises a circular pipe body and a convex edge arranged on the outer wall of the pipe body and extending outward in the radial direction of the pipe body. The direction adjustment assembly is located at the front side of the frame and is used for adjusting the direction of the special-shaped pipe to a predetermined direction. The first conveying assembly is used for conveying the special-shaped pipes from the feeding assembly to the direction adjustment assembly one by one from the rear to the front. The pushing assembly and the second conveying assembly are respectively located on the left and right sides of the direction adjustment assembly. The pushing assembly is used for pushing a part of the special-shaped pipe located on the direction adjustment assembly onto the second conveying assembly. The second conveying assembly is used for conveying the special-shaped pipes from the direction adjustment assembly to the material taking station.

[0027] See again Figure 4 As shown, the frame 1 is also rotatably connected to a plurality of support rollers 11 which are spaced from left to right, the axis of each support roller 11 extends from front to back, the upper edge of the support roller 11 is on the same horizontal plane as the bottom surface of the support groove 413, and the plurality of support rollers 11 are used to support the special-shaped tube 7 which falls into the support groove 413; by setting the plurality of support rollers 11, and the upper edge of the support roller 11 is on the same horizontal plane as the bottom surface of the support groove 413, the plurality of support rollers 11 can cooperate with the plurality of support blocks 41 to support the special-shaped tube 7.

Subsequently, the special-shaped pipe 7 can be conveyed to the material taking station 8 through the second conveying assembly 6; when the cylinder 51 drives the pushing plate 52 to move toward the side away from the direction adjusting assembly 4, the pushing plate 52 can move back to its original position.

[0030] Refer to again Figure 8As shown in the figure, the second conveying component 6 includes a chain-type second conveyor belt 61; the second conveyor belt 61 is connected to the frame 1 and extends from left to right. A plurality of magnets 62 are fixed on the outer peripheral wall of the chain 611 in the second conveyor belt 61 and are spaced apart in the circumferential direction of the chain 611.

After adopting this second conveying component 6, when the special-shaped pipe 7 located on the direction adjustment component 4 is partially pushed out onto the second conveying component 6 by the pushing component 5, the right end of the special-shaped pipe 7 can be magnetically attracted to an individual magnet 62 located on the chain 611. At the same time, in cooperation with the rotation of the chain 611, the magnet 62 can pull the special-shaped pipe 7 and finally convey the special-shaped pipe 7 to the material-taking station 8.

[0031] When the present invention is working, first, the feeding component 2 can convey the special-shaped pipes 7 one by one to the feeding end of the first conveying component 3. Then, the first conveying component 3 can convey the special-shaped pipes 7 from the feeding component 2 one by one from back to front into the direction adjustment component 4. The orientation of the convex edge 72 in the special-shaped pipe 7 entering the direction adjustment component 4 can be adjusted and determined. Subsequently, the pushing component 5 can partially push the special-shaped pipe 7 located on the direction adjustment component 4 onto the second conveying component 6. Finally, the second conveying component 6 can convey the special-shaped pipes 7 from the direction adjustment component 4 to the material-taking station 8, and the orientations of the convex edges 72 on all the special-shaped pipes 7 conveyed to the material-taking station 8 are the same, so as to facilitate the manipulator in the subsequent station to pick up the special-shaped pipes 7.

[0032] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
