DETAILED DESCRIPTION

[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0031] Reference Figure 1 、 Figure 2 and Figure 3 This embodiment provides a pipe delivery mechanism, including a workbench (not shown in the figure), a first positive V-shaped wavy pipe holder 1, a second positive V-shaped wavy pipe holder 2, a triangular toothed pipe delivery lifting assembly 3 and a pipe removal arm assembly 4.

[0032] A first positive V-shaped corrugated pipe fixture support 1 and a second positive V-shaped corrugated pipe fixture support 2 are arranged side by side on the upper surface of the workbench and extend in the left-right direction. The upper parts of the first positive V-shaped corrugated pipe fixture support 1 and the second positive V-shaped corrugated pipe fixture support 2 have two or more correspondingly arranged troughs, and each group of corresponding troughs constitutes a station for placing pipe fixtures;

[0033] A triangular toothed pipe delivery lifting assembly 3 is provided between the first positive V-shaped wavy pipe fixture support 1 and the second positive V-shaped wavy pipe fixture support 2 on the workbench, and a pipe retrieval arm assembly 4 is provided on the outside of the first positive V-shaped wavy pipe fixture support 1 and the second positive V-shaped wavy pipe fixture support 2 on the workbench. Both the triangular toothed pipe delivery lifting assembly 3 and the pipe retrieval arm assembly 4 can lift the pipes in the workstation and move them laterally in the left and right directions respectively, passing over the highest peaks of the first positive V-shaped wavy pipe fixture support 1 and the second positive V-shaped wavy pipe fixture support 2.

[0034] Furthermore, the triangular toothed pipe delivery lifting assembly 3 is provided with a pipe delivery surface extending in the lower left direction at each workstation. The pipe delivery surface can lift the pipe in the workstation toward the upper left, so that the pipe passes over the highest peak of the first positive V-shaped wavy pipe support 1 and the second positive V-shaped wavy pipe support 2 and moves laterally toward the left side of the workbench.

[0035] The pipe-taking arm assembly 4 can lift the pipe in the workstation toward the upper right, so that the pipe passes over the highest peak of the first positive V-shaped pipe holder 1 and the second positive V-shaped pipe holder 2, and moves horizontally toward the right side of the workbench. Figure 1 The left and right sides of the patent are relative terms, not absolute directions.

[0036] The pipe transfer mechanism of this embodiment adopts a first positive V-shaped wavy pipe holder 1, a second positive V-shaped wavy pipe holder 2, a triangular toothed pipe delivery lifting assembly 3 and a pipe removal arm assembly 4, which can stably and effectively complete the horizontal transfer of pipes between workstations.

[0037] In this embodiment, the first positive V-shaped corrugated pipe fixture support 1 is equipped with V-shaped rubber friction blocks 11 at the bottom of some workstations, forming the corrugated troughs. The first positive V-shaped corrugated pipe fixture support 1 is equipped with rollers 12 at the bottom of the remaining workstations, forming the corrugated troughs. The V-shaped rubber friction blocks 11 increase friction with the pipe fixture to prevent axial movement, while the rollers 12 reduce friction with the pipe fixture, facilitating axial adjustment of the pipe fixture's position.

[0038] Furthermore, the roller 12 may be a V-shaped roller, or may be a plurality of small rollers, wherein the plurality of small rollers form a V-shape.

[0039] In this embodiment, three workstations are arranged from right to left on the upper portions of the first and second positive V-shaped corrugated pipe fixture supports 1 and 2, namely, the first workstation 4, the second workstation 5, and the third workstation 6. It should be noted that the pipe fixture can be moved laterally from the first workstation 4 to the second workstation 5, and then from the second workstation 5 to the third workstation 6; alternatively, the pipe fixture can be moved laterally from the third workstation 6 to the second workstation 5, and then from the second workstation 5 to the first workstation 4.

[0040] In this embodiment, the first positive V-shaped wave-shaped pipe fixture support 1 is provided with V-shaped rubber friction blocks 11 at the lower parts of the first station 4 and the third station 6 , and the V-shaped rubber friction blocks 11 form wave troughs.

[0041] Furthermore, the first positive V-shaped corrugated pipe fixture support 1 of this embodiment is provided with a roller 12 at the lower portion of the second work station 5 .

[0042] The triangular-toothed tube delivery lifting assembly 3 of this embodiment comprises a triangular-toothed tube delivery bracket 31 and a first oil cylinder 32. The first oil cylinder 32 is mounted vertically on a workbench, with the piston rod end of the first oil cylinder 32 fixedly connected to the bottom surface of the triangular-toothed tube delivery bracket 31. A triangular-toothed protrusion 311 is provided on the upper portion of the triangular-toothed tube delivery bracket 31, corresponding to each workstation. The triangular-toothed protrusion 311 has a vertical surface and a tube delivery surface that slopes downward and to the left.

[0043] The pipe is placed on the first workstation 4 or the second workstation 5. When the pipe needs to be transferred from the first workstation 4 to the second workstation 5 and from the second workstation 5 to the third workstation 6, the first oil cylinder 32 lifts the triangular tooth pipe delivery bracket 31, and the pipe delivery surface of the triangular tooth protrusion 311 abuts against the pipe in the workstation and pushes the pipe to the left side of the workbench; the first oil cylinder 32 continues to output, and the pipe delivery surface of the triangular tooth protrusion 311 gradually becomes higher than the highest peak of the positive V-shaped wavy pipe bracket 2, thereby allowing the pipe to pass over the highest peak of the positive V-shaped wavy pipe bracket 2 and roll into another adjacent workstation.

[0044] In this embodiment, connecting plates are provided between the left end of the first positive V-shaped wavy pipe fixture support 1 and the left end of the second positive V-shaped wavy pipe fixture support 2, as well as between the right end of the first positive V-shaped wavy pipe fixture support 1 and the right end of the second positive V-shaped wavy pipe fixture support 2. The two connecting plates are located on the left and right sides of the triangular tooth-shaped pipe delivery lifting assembly 3. Guide assemblies are provided between the two connecting plates and the two ends of the triangular tooth-shaped pipe delivery lifting assembly 3. The guide assemblies guide the triangular tooth-shaped pipe delivery lifting assembly 3 in the vertical direction.

[0045] Furthermore, the guide assembly is a roller guide rail assembly.

[0046] See also Figure 3 The pipe retrieval arm assembly 4 of this embodiment includes a pipe retrieval arm 41 and a second cylinder 42. The right end of the rear side of the second V-shaped corrugated pipe support 2 is hinged to one end of the pipe retrieval arm 41, the other end of the pipe retrieval arm 41 is hinged to one end of the second cylinder 42, and the other end of the second cylinder 42 is hinged to the workbench.

[0047] The pipe is placed on the third workstation 6 or the second workstation 5. When the pipe needs to be transferred from the third workstation 6 to the second workstation 5 and from the second workstation 5 to the first workstation 4, the second oil cylinder 42 drives the pipe-taking arm 41 to rotate to the right around the hinge point between the pipe-taking arm 41 and the second positive V-shaped wave-shaped pipe holder 2, so that the pipe-taking arm 41 abuts against the pipe in the workstation and pushes the pipe to the right side of the workbench, so that the pipe passes over the highest peak of the positive V-shaped wave-shaped pipe holder 2 and rolls to the right to another adjacent workstation.
