Description

Technical Field

[0001] The utility model belongs to the technical field of feeding, and in particular relates to a pipe feeding device. Background Art

[0002] With the development of the industrial automation industry, automated production lines are becoming increasingly widespread. Simultaneously, there is a growing demand for intelligent, automated equipment. During the steel pipe production process for power plant boilers, pipes are cut to length, typically ranging from 1.5 to 12.5 meters. After stock preparation, the pipes are traditionally dropped from racks on processing equipment into a silo via free fall. In existing technology, the prepared pipes are dropped from racks approximately one meter high into a silo for stacking. While the silo can be equipped with shock-absorbing materials to mitigate impact noise at the point where the first pipe falls, the noise generated by the collision of pipes from the second pipe onwards cannot be avoided. Stacking the pipes requires a mobile trolley and a robotic arm, which not only takes up considerable space in terms of height, but also requires a large workshop space for the robotic arm structure. This creates a high demand for space resources and wastes space resources. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a pipe feeding and receiving device, which can reduce the noise when the pipes are stacked and can also reduce the space occupied in the height direction.

[0004] The embodiments of the present invention are achieved through the following technical solutions:

[0005] A pipe feeding and receiving device includes a turning structure, a transport structure and a material rack. The transport structure includes a chain and a supporting rod provided on the chain. The supporting rod receives the pipe from the turning structure and feeds the pipe into the material rack in a vertical direction.

[0006] In one embodiment of the present invention, the chain is provided with a connecting piece, and the supporting rod is rotatably connected to the connecting piece within a limited angle.

[0007] In one embodiment of the present invention, the supporting rod is provided with a supporting surface, a limiting surface and a pipe unloading guide surface. The supporting surface, the limiting surface and the pipe unloading guide surface together form a triangular block. The supporting surface is used to support the pipe material, and the limiting surface can abut against the connecting piece.

[0008] In an embodiment of the present invention, when the limiting surface abuts against the connecting member, the bearing support rod is located at the bearing position.

[0009] In one embodiment of the present invention, a reset torsion spring is provided between the support rod and the connecting member.

[0010] In one embodiment of the present invention, when the load-bearing support rod is at the load-bearing position, the angle between the load-bearing support rod and the chain is an acute angle α.

[0011] In one embodiment of the present invention, the material rack is a U-shaped rack, and a vibration-damping and noise-reducing strip is provided at the bottom of the U-shaped rack.

[0027] Example

[0028] Please refer to Figure 1-3This embodiment provides a pipe feeding and receiving device, which includes a turning structure, a transport structure, and a material rack 3. The turning structure includes a conveyor rack 11, a turning plate 12, and a turning cylinder 13. The conveyor rack 11 is mounted with a conveying roller 14. A turning shaft 15 is also mounted on the conveyor rack 11. A plurality of turning plates 12 are mounted on the turning shaft 15. A connecting rod 16 is also mounted on the turning shaft 15, which is hingedly connected to the turning cylinder 13. The turning cylinder 13 is hingedly connected to the conveyor rack 11. It should be noted that the flipping plate 12 is provided with a sharp hook portion 121 and a material guide portion 122. The sharp hook portion 121 is located near one end of the conveyor frame 3, and the material guide portion 122 is flat and smoothly transitions with the sharp hook portion 121. In the initial state, the flipping cylinder 13 is in a retracted state, driving the flipping plate 12 to the initial position, with the sharp hook portion 121 located below the conveyor roller 14. When flipping is required, the flipping cylinder 13 is extended and drives the flipping shaft 15 to rotate via the connecting rod 16, so that the flipping plate 12 rotates from the conveyor frame 3 to the material frame 3, that is, the sharp hook portion 121 of the flipping plate 12 hooks the pipe 4. When flipping, the pipe 4 is prevented from slipping out of the side of the sharp hook portion 121 of the flipping plate 12, which would cause the flipping to fail. When the flipping plate 12 successfully hooks the pipe 4, the flipping plate 12 continues to flip, and the pipe 4 slides down along the material guide portion 122 of the flipping plate 12.

[0029] It should be noted that, as needed, a shock-absorbing strip or a noise-reducing strip made of rubber may be provided on the surface of the flipping plate 12 to reduce noise.

[0030] Please refer to Figure 4-6 In this embodiment, a transport structure is provided on the rack 3 for feeding the pipe 4 into the rack 3 in a vertical direction. Specifically, the transport structure includes a chain 21, a gear 22, a transport shaft 23, and a supporting rod 24 provided on the chain 21. Two transport shafts 23 are provided and are arranged parallel to each other. Each transport shaft 23 is equipped with a plurality of gears 22, the number of which is the same as the number of the flipping plates 12. The chain 21 is wound between the two gears 22 of the upper and lower transport shafts 23. One of the two transport shafts 23 is selected to be connected to the motor. The supporting rod 24 receives the pipe 4 from the flipping structure and feeds the pipe 4 to the rack 3. The present application feeds the pipe 4 into the rack 3 in a vertical direction through the transport structure, which is beneficial for reducing the travel of the pipe 4 and reducing the space occupied by the pipe 4 receiving and feeding device in the horizontal direction. That is, the provision of the transport mechanism does not increase the size of the pipe 4 receiving and feeding device in the horizontal plane.

[0031] Please refer to Figure 4-6In this embodiment, the chain 21 is fixed with a connecting piece 25, and the load-bearing support rod 24 is hinged to the connecting piece 25. Moreover, with the hinge axis as the rotation axis, the load-bearing support rod 24 can be rotated within a limited angle. Specifically, the load-bearing support rod 24 is triangular, including a supporting surface 241, a limiting surface 242 and a pipe unloading guide surface 243. The supporting surface 241 is used to support the pipe material 4, and the limiting surface 242 can abut against the connecting piece 25. A reset torsion spring 26 is also provided between the load-bearing support rod 24 and the connecting piece 25. When the load-bearing support rod 24 is not in contact with the pipe material 4, that is, the load-bearing support rod 24 is in the initial state, that is, the load-bearing position, under the action of the reset torsion spring 26, the load-bearing support rod 24 rotates along the S direction until the limiting surface 242 abuts against the connecting piece 25. Due to the restriction of the limiting surface 242, the load-bearing support rod can no longer rotate. When the pipes 4 have been placed on the supporting rod 24 and the supporting rod 24 has been rotated to one side of the rack 3, and some pipes 4 have already been placed on the rack 3, as the chain 21 rotates, the pipe unloading guide surface 243 of the supporting rod 24 contacts the pile of pipes 4 on the rack 3, and then the supporting rod 24 rotates in the N direction around the hinge axis until the pipes 4 on the supporting rod 24 are placed on the rack 3. After the supporting rod 24 passes over the pile of pipes 4 on the rack 3, the supporting rod 24 returns to the carrying position under the action of the return torsion spring 26. In this embodiment, the supporting rod 24 is used, and the pipes 4 can overcome gravity under the action of the supporting rod 24, and as the supporting rod 24 descends, the pipes 4 are moved to the rack 3 or the pipes in the rack 3 at a controllable speed.

[0032] Please refer to Figure 4-6 It should be noted that when the load-bearing support rod 24 is in the initial position and the load-bearing support rod 24 is in the straight section of the chain 21, the angle between the supporting surface 241 of the load-bearing support rod 24 and the chain 21 is an acute angle α, that is, the end of the load-bearing support rod 24 connected to the connecting member 25 is lower than the free end of the load-bearing support rod 24 to form a high and low structure. When the pipe 4 is placed on the load-bearing support rod 24, the pipe 4 can be stably placed between the load-bearing support rod and the chain 21, which can prevent the pipe 4 from slipping off the load-bearing support rod 24.

[0033] Please refer to Figure 1-3 In this embodiment, the rack 3 is a U-shaped rack, and the handling structure places the pipes 4 one by one in the U-shaped rack. In order to reduce the noise generated by the interaction between the pipes and the rack 3, a vibration-damping and noise-reducing strip 31, such as a rubber strip, is also provided in the U-shaped rack.

[0034] The present invention adopts a material turning structure to transfer the pipe 4 to the conveying structure, and then places the pipe 4 from top to bottom into the material rack 3 through the chain 21 and the load-bearing support rod 24 of the conveying structure. Compared with the existing technology, the conveying structure with the chain 21 and the load-bearing support rod 24 adopted in the present invention can reduce the noise when the pipe 4 is stacked, and can also reduce the space occupied in the height direction.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
