Description

Technical Field

[0001] This utility model belongs to the field of aerated concrete panel production technology, and more specifically, relates to a mesh conveyor trolley circulating transport equipment. Background Technology

[0002] Aerated concrete panels are a type of building material. They are lightweight, porous materials formed by adding aerated concrete to the exterior, using metal mesh as the internal structure. Aerated reinforced concrete panels, also known as aerated boards, have a lower density than cement boards and possess excellent fire resistance, sound insulation, heat insulation, and thermal insulation properties.

[0003] Currently, in autoclaved aerated concrete (AAC) block production lines, some companies use plastic clip-on wire mesh cages. When assembling a plastic clip-on wire mesh cage, the dimensions of the saddle frame steel bars are typically adjusted manually first, then the plastic clips are fixed in place using the steel bars. Finally, multiple people work together to clip the wire mesh pieces onto the plastic clips, forming the plastic clip-on wire mesh cage. Before clipping the wire mesh pieces onto the plastic clips, the wire mesh pieces need to be transported to the wire mesh clipping station via a trolley for the clipping work. After the clipping work is completed, the wire mesh transport trolley returns empty to the wire mesh loading station to transport the next batch of wire mesh pieces.

[0004] However, during the process of the wire mesh conveyor trolley returning empty to the wire mesh loading station for loading and then returning again to the wire mesh clamping station for clamping, the clamping work is stopped, meaning the production of aerated concrete panels is paused. Therefore, the production efficiency of aerated concrete panels is reduced. To improve competitiveness, aerated concrete panel manufacturers are demanding increasingly higher annual production capacity and shorter cycle times for each stage. This inefficient wire mesh conveying method can no longer meet these rising production capacity requirements.

[0005] A search revealed a Chinese patent application (CN202310717455.4, published on September 15, 2023) disclosing a plastic mesh cage assembly machine and its usage method, belonging to the technical field of aerated concrete panel production lines. The invention includes an assembly machine base, an assembly conveying trolley, and a lifting vehicle assembly. The assembly machine base has a mesh-retrieving station and a first assembly station. The assembly conveying trolley is mounted on the assembly machine base and moves laterally on it. The lifting vehicle assembly is used to place and transport the plastic mesh cages. The lifting vehicle assembly is mounted on the assembly conveying trolley and moves vertically on it to lift the plastic mesh cages. The lifting vehicle assembly includes a mesh-hanging component, which engages and positions the two mesh pieces of the plastic mesh cage and pushes the plastic clamps laterally, engaging with steel rods to complete the assembly operation. This invention uses a fixed track to allow the mesh conveying trolley to run back and forth to transport the mesh sheets. However, this addresses the problem mentioned earlier where the mesh conveying trolley returns empty to load mesh sheets before reaching the mesh sheet clamping station again, causing the mesh sheet clamping work to stop and reducing the production efficiency of aerated concrete panels. Summary of the Invention

By setting up two sets of mesh conveying trolleys and improving their structure, the two sets of trolleys can alternate positions, thereby achieving cyclical conveying of the mesh and ensuring continuous mesh clamping, thus improving the production efficiency of aerated concrete panels.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] (1) The present invention provides a mesh conveying trolley circulation transport device. When the first conveying trolley is performing mesh clamping work at the mesh clamping station, the second conveying trolley moves to the mesh feeding station to feed the mesh through a transverse drive mechanism. Then the second conveying trolley returns to the second conveying track and moves to the vicinity of the mesh clamping station. When the first conveying trolley returns empty to feed the mesh, the second conveying trolley moves to the mesh clamping station to perform mesh clamping work through a transverse drive mechanism. After the second conveying trolley finishes clamping the mesh, the first conveying trolley, which has finished feeding the mesh, moves to the mesh clamping station to continue working, while the second conveying trolley returns to the mesh feeding station. The two sets of trolleys work alternately in a cycle, which enables the mesh clamping work to continue and improves the production efficiency of aerated concrete panels.

[0032] Exemplary embodiments of the present invention are described in detail below. While these exemplary embodiments have been described in sufficient detail to enable those skilled in the art to practice the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from its spirit and scope. The more detailed description of embodiments of the present invention below is not intended to limit the scope of the claimed invention, but is merely illustrative and does not limit the description of the features and characteristics of the invention, in order to provide the best mode for carrying out the invention and sufficient to enable those skilled in the art to practice it. Therefore, the scope of the present invention is defined only by the appended claims.

[0033] Example 1

[0034] A wire mesh conveying trolley circulation transport device is used in an autoclaved aerated concrete (AAC) block production line employing plastic wire mesh cages to deliver wire mesh to the wire mesh clamping station. This device is also applicable to other concrete block production processes where wire mesh needs to be transported to a designated location. The specific structure and technical effects of this circulation transport device are described in detail below.

[0035] like Figure 1 and Figure 2 As shown, the circulating transport equipment includes a first conveying track 1 and a second conveying track 5 arranged parallel to the first conveying track 1. One end of the first conveying track 1 is a mesh feeding station 2, and the other end is a mesh clamping station 3, on which a first conveying trolley 4 is mounted to transport the mesh along the first conveying track 1. A longitudinal drive mechanism 6 is provided on the second conveying track 5 to move along the second conveying track 5, and a transverse drive mechanism 8 is provided on the longitudinal drive mechanism 6 to drive the second conveying trolley 7 to move perpendicular to the second conveying track 5. In this embodiment, the mesh feeding station 2 is operated manually or by a robotic arm to grip the mesh onto the conveying trolley. The mesh clamping station is equipped with a mesh clamping device 10 that removes the mesh from the trolley and clamps it onto a plastic card. The mesh clamping device 10 can be a commercially available mechanical gripper or robotic arm.

[0036] Specifically, such as Figures 3 to 5 As shown, the longitudinal drive mechanism 6 includes a support frame 61, a longitudinal drive gear 62, a longitudinal drive rack 63, and a longitudinal drive motor 64. The support frame 61 has a slider at its bottom that is slidably connected to the second conveying track 5. The longitudinal drive motor 64 is fixedly mounted on the support frame 61 and is connected to the longitudinal drive gear 62 for transmission. The longitudinal drive rack 63 is arranged along the second conveying track 5 and meshes with the longitudinal drive gear 62. By driving the longitudinal drive gear 62 to rotate along the longitudinal drive rack 63 via the longitudinal drive motor 64, the support frame 61 can drive the second conveying trolley 7 to move along the second conveying track 5.

[0037] The transverse drive mechanism 8 includes a transverse slider 81, a transverse chute 82, a transverse drive gear 83, a transverse drive rack 84, and a transverse drive motor 85. The transverse chute 82 is fixedly mounted on the support frame 61, and the transverse slider 81 is slidably connected to the transverse chute 82 and perpendicular to the second conveying track 5. The transverse drive gear 83 is mounted on the support frame 61, and the transverse drive rack 84 is perpendicular to the second conveying track 5 and mounted on the transverse slider 81, meshing with the transverse drive gear 83. The transverse drive motor 85 is fixedly mounted on the support frame 61 and is connected to the transverse drive gear 83 for transmission. The second conveying trolley 7 is mounted on the transverse slider 81. By driving the transverse drive gear 83 to rotate along the transverse drive rack 84 via the transverse drive motor 85, the transverse slider 81 and the second conveying trolley 7 on the transverse slider 81 can be moved upwards towards the first conveying track 1, positioning the second conveying trolley 7 at the mesh feeding station 2 or the mesh clamping station 3.

[0038] It should be noted that the bottom height of the horizontal slider 81 needs to be higher than the top height of the first conveying track 1, and the stroke length of the horizontal slider 81 needs to support the second conveying trolley 7 to move to the mesh feeding station 2 or the mesh clamping station 3.

[0039] Furthermore, due to the relatively long length of the second conveying trolley 7, multiple transverse sliders 81 are provided to ensure the transverse movement of the second conveying trolley 7. The transverse sliders 81 are spaced apart on the support frame 61, and in this embodiment, there are five. However, in this embodiment, only a single transverse drive motor 85 is provided, which is connected to a synchronous shaft, and multiple transverse drive gears 83 are all mounted on the synchronous shaft. This arrangement allows for cost savings by using a single motor to control the movement of multiple transverse sliders 81, and also ensures the consistency of the movements of the multiple transverse sliders 81, preventing equipment damage caused by deviations in the movement of a single transverse slider 81.

[0040] In terms of the mesh placement structure, multiple mesh placement frames 9 are spaced apart on both the first conveying trolley 4 and the second conveying trolley 7. Each mesh placement frame 9 has slots for placing the mesh, and a single mesh is secured in one of these slots. Simultaneously, the second conveying trolley 7 is equipped with an adjusting rail 71 extending along the second conveying track 5. The mesh placement frames 9 are slidably mounted on the adjusting rail 71. The first conveying trolley 4 also has the same structure, and a rail lock is installed at the bottom of each mesh placement frame 9. This arrangement allows the mesh placement frames 9 to adjust their position on the conveying trolley according to the length of the mesh, ensuring the mesh is better secured in the slots of the mesh placement frames 9.

[0041] In addition, limit blocks are provided at the ends of the adjusting track 71, the second conveying track 5 and the first conveying track 1, and flexible pads are provided on the inner side of the limit blocks. This can prevent the mesh placement frame 9, the support frame 61 and the first conveying trolley 4 from leaving the track, while reducing the collision force between the limit blocks and the mesh placement frame 9, the support frame 61 and the first conveying trolley 4, thus reducing equipment damage.

[0042] The working process of this circulating transport equipment is as follows: When the first conveyor trolley 4 is performing mesh clamping work at the mesh clamping station 3, the second conveyor trolley 7 moves to the mesh loading station 2 to clamp the mesh via the transverse drive mechanism 6. Then, the second conveyor trolley 7 returns to the second conveyor track 5 and moves to the vicinity of the mesh clamping station 3. When the first conveyor trolley 4 returns empty to clamp the mesh, the second conveyor trolley 7 moves to the mesh clamping station 3 via the transverse drive mechanism 6 to perform mesh clamping work. After the second conveyor trolley 5 finishes clamping the mesh, the first conveyor trolley 4, having finished clamping the mesh, moves to the mesh clamping station 3 to continue working, while the second conveyor trolley 7 returns to the mesh loading station 2. The two sets of trolleys work alternately in a cycle, enabling the mesh clamping work to continue continuously and improving the production efficiency of aerated concrete panels.

[0043] In summary, the mesh conveying trolley circulation transport equipment of this embodiment, by setting up two sets of mesh conveying trolleys and improving the structure of the mesh conveying trolleys, enables the two sets of mesh conveying trolleys to alternate positions, thereby realizing the circulation transport of mesh, allowing the mesh clamping work to continue, and improving the production efficiency of aerated concrete panels.
