Description

Technical Field

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

[0002] An IBC frame is a framework structure suitable for supporting and securing ton barrels. It consists of a chassis and a frame body. The frame body is welded from steel pipes, while the chassis is made of galvanized steel sheet with rounded corners. The frame body protects the ton barrels from damage due to external impacts, so it requires high structural strength. Currently, frames are mainly divided into circular tubular frames and square tubular frames. Circular tubular frames are made of round steel pipes, while square tubular frames are made of square steel pipes.

[0003] Furthermore, the special-shaped tube is a component used for welding and fixing at the upper end of the above-mentioned frame body. The special-shaped tube includes a circular tube body and a convex edge arranged on the outer wall of the tube body and extending outward in the radial direction of the tube body. Currently, before the special-shaped tube is welded to the frame body in the ton barrel frame, the direction of the special-shaped tube is determined manually and the special-shaped tube is placed at the waiting station of the welding machine manually, which results in low feeding efficiency of the special-shaped tube and high labor cost.

[0004] To this end, the current Chinese patent announcement number: CN215827805U discloses a pipe feeding device, which can change the inclination angle of the material rack of the material receiving rack, so that the pipe feeding device can be suitable for feeding a variety of pipes including special-shaped pipes. When in use, it is only necessary to adjust the height adjustment mechanism according to the movement of the pipe on the support structure to ensure smooth transportation of the pipe, thereby improving the adaptability of the pipe feeding device.

[0005] However, in the above-mentioned pipe feeding device structure, although it can realize the feeding of special-shaped pipes, it is difficult to adjust and determine the direction of the special-shaped pipes after the special-shaped pipes are loaded, that is, when the pipe feeding device supplies the special-shaped pipes to the outside, the discharge direction of the special-shaped pipes is uncertain, which makes it difficult to meet the welding requirements of the welding machine for the special-shaped pipes and the frame body in the ton barrel frame.

[0039] When the present invention is working, first the loading component 2 can convey the special-shaped tubes 7 one by one to the feed end of the first conveying component 3, then the first conveying component 3 can convey the special-shaped tubes 7 from the loading component 2 one by one to the direction adjustment component 4 from back to front, and the orientation of the convex edge 72 of the special-shaped tube 7 entering the direction adjustment component 4 can be adjusted and determined, and then the pushing component 5 can push the part of the special-shaped tube 7 located on the direction adjustment component 4 to the second conveying component 6, and finally the second conveying component 6 can convey the special-shaped tube 7 from the direction adjustment component 4 to the waiting material station 8, and the orientation of the convex edges 72 on all the special-shaped tubes 7 conveyed to the waiting material station 8 is consistent, so that the robot in the subsequent station can take the special-shaped tube 7.

[0040] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
