Description

Technical Field

[0001] The invention relates to a logistics device, and more specifically to a shelf docking system capable of self-circulating workpieces. Background Art

[0002] Factory production and some logistics systems still use manual operations to move goods from material carts. Even with AGVs, some goods still need to be moved manually. Therefore, it is necessary to design a system that can automatically transfer goods to workers to facilitate their operation. Since there are generally a large number of material carts, it is impossible to add power devices such as batteries for cost considerations, so the system also needs to be fully implemented mechanically. Summary of the invention

[0003] The present invention aims to solve the above technical problems at least to a certain extent. To this end, the present invention proposes a shelf docking system that can self-circulate workpieces, so as to replace the traditional method of manually transporting goods from material vehicles without consuming additional power, thereby reducing production costs and occupation of personnel and improving work efficiency.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] A shelf docking system that can self-circulate workpieces has the following structural features:

[0006] Including fixed shelves and mobile shelves that can be docked one after the other and both have double-layer structures;

[0007] The upper layer of the fixed shelf is the first discharging roller group, and the lower layer is the first feeding roller group; the upper layer of the mobile shelf is the second feeding roller group, and the lower layer is the second discharging roller group; the rear end of the mobile shelf can be connected with the front end of the fixed shelf; when connected, the first discharging roller group on the upper layer is connected with the second feeding roller group to form a complete upper inclined surface with a high back and a low front; the first feeding roller group on the lower layer is connected with the second discharging roller group to form a complete lower inclined surface with a high front and a low back;

[0008] It also includes an upper sliding shaft assembly and a lower sliding shaft assembly arranged between the docking surface of the mobile shelf and the fixed shelf, and the upper sliding shaft assembly and the lower sliding shaft assembly both include a sliding shaft, a damper, a pressure block and a material blocking rod. The pressure block can be vertically displaced through the docking of the mobile shelf and the fixed shelf, and the material blocking rod on the sliding shaft is driven to rise and fall through the damper. The upper sliding shaft assembly blocks / releases materials on the upper complete inclined surface through the rise / fall of the upper material blocking rod, and the lower sliding shaft assembly releases / blocks materials on the lower complete inclined surface through the rise / fall of the lower material blocking rod.

[0009] The structural characteristics of the present invention also lie in:

[0010] The left and right sides of the front end of the fixed shelf are provided with symmetrically arranged guide tubes, and the guide tubes are cantilevered forward. The mobile shelf connected to the fixed shelf can be adaptively placed in the area between the pair of guide tubes.

[0011] The upper sliding shaft assembly includes an upper pressure block, an upper sliding shaft, an upper damper, and an upper material stopping rod. The upper pressure block is installed on the upper rear end of the main frame of the mobile shelf. The upper sliding shaft and the upper material stopping rod are vertically movably coaxially mounted on the upper front end of the main frame of the fixed shelf, with an upper damper tensioned therebetween. When the upper material stopping rod is supported by the upper damper in a natural state, it is located closely above the upper complete inclined surface to form a barrier to the materials on the upper complete inclined surface. When the mobile shelf is lowered from top to bottom to connect with the fixed shelf, the upper pressure block can press the upper material stopping rod downward to be lower than the upper complete inclined surface to release the materials on the upper complete inclined surface.

[0012] The lower sliding shaft assembly includes a lower pressing block, a lower sliding shaft, a lower damper, and a lower material stopping rod. The lower pressing block is installed at the front lower part of the main frame of the fixed shelf. The lower sliding shaft and the lower material stopping rod are coaxially mounted on the rear lower part of the main frame of the mobile shelf, and are vertically movably mounted. The lower damper is mounted. When the lower material stopping rod is supported by the lower damper in a natural state, the height at which it is located can block the materials on the complete inclined surface of the lower layer. When the mobile shelf is lowered from top to bottom to connect with the fixed shelf, the lower pressing block can push the lower material stopping rod upward to a height position above the materials on the complete inclined surface of the lower layer, thereby releasing the materials on the complete inclined surface of the lower layer.

[0013] A pair of upper sliding shaft assemblies are provided, which are symmetrically arranged on the left and right sides of the upper ends of the main frames of the fixed shelf and the movable shelf.

[0014] A pair of lower sliding shaft components are provided, which are symmetrically arranged on the left and right sides of the lower ends of the main frames of the fixed shelf and the movable shelf.

[0015] The fixed shelves and the movable shelves are respectively provided with upper guardrails and lower guardrails which are symmetrically arranged on the left and right, corresponding to the upper complete inclined surface and the lower complete inclined surface.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The present invention arranges a fixed shelf and a mobile shelf for use as a set. When the two are docked, the lower layer of the mobile shelf is used for discharging materials and is received by the lower layer of the fixed shelf, and the upper layer of the fixed shelf is used for discharging materials and is received by the upper layer of the mobile shelf. By arranging an upper sliding shaft assembly and a lower sliding shaft assembly, when the fixed shelf and the mobile shelf are docked, the upper material blocking rod and the lower material blocking rod are vertically displaced accordingly to release the obstruction to the material, so that the workpiece can slide freely by its own weight to realize self-circulation. When the fixed shelf and the mobile shelf are separated, the obstruction to the material is restored. The self-circulation process of the workpiece does not require human participation and does not require electrical connection, so it is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

Both the upper and lower roller groups are installed on the main frame 4 of the fixed shelf. The upper layer of the mobile shelf 6 is the second feeding roller group 7, and the lower layer is the second discharging roller group 8. Both the upper and lower roller groups are installed on the main frame 9 of the mobile shelf. The rear end of the mobile shelf 6 can be connected with the front end of the fixed shelf 1. When connected, the first discharging roller group 2 on the upper layer is connected with the second feeding roller group 7 to form a complete upper inclined surface with a high back and a low front, and the first feeding roller group 3 on the lower layer is connected with the second discharging roller group 8 to form a complete lower inclined surface with a high front and a low back.

[0028] It also includes an upper sliding shaft 11 component and a lower sliding shaft 15 component arranged between the docking surface of the mobile shelf 6 and the fixed shelf 1. The upper sliding shaft 11 component and the lower sliding shaft 15 component both include a sliding shaft, a damper, a pressure block and a material blocking rod. The pressure block can be vertically displaced through the docking of the mobile shelf 6 and the fixed shelf 1, and the damper drives the material blocking rod on the sliding shaft to rise and fall. The upper sliding shaft 11 component blocks / releases the material on the upper complete inclined surface by rising / falling the upper material blocking rod 13, and the lower sliding shaft 15 component releases / blocks the material on the lower complete inclined surface by rising / falling the lower material blocking rod 17.

[0029] In the specific implementation, the corresponding structural settings also include:

[0030] The left and right sides of the front end of the fixed shelf 1 are provided with symmetrically arranged guide tubes 5, which are cantilevered forward. The mobile shelf 6 connected to the fixed shelf 1 can be adaptively placed in the area between a pair of guide tubes 5, which is convenient for positioning the mobile shelf 6 during docking.

[0031] The upper sliding shaft 11 assembly includes an upper pressing block 10, an upper sliding shaft 11, an upper damper 12, and an upper material blocking rod 13. The upper pressing block 10 is installed on the upper rear end of the main frame 9 of the mobile shelf. The upper sliding shaft 11 and the upper material blocking rod 13 are vertically movably coaxially sleeved on the upper front end of the main frame 4 of the fixed shelf, with the upper damper 12 tensioned therebetween. When the upper material blocking rod 13 is supported by the upper damper 12 in the natural state, it is adjacent to the upper part of the upper complete inclined surface, thereby blocking the materials on the upper complete inclined surface. When the mobile shelf 6 is lowered from top to bottom to connect with the fixed shelf 1, the upper pressing block 10 can press the upper material blocking rod 13 downward to below the upper complete inclined surface, thereby releasing the materials on the upper complete inclined surface.

[0032] The lower sliding shaft 15 assembly includes a lower pressing block 14, a lower sliding shaft 15, a lower damper 16, and a lower material blocking rod 17. The lower pressing block 14 is installed at the front lower part of the main frame 4 of the fixed shelf, and the lower sliding shaft 15 and the lower material blocking rod 17 are vertically movably coaxially mounted on the rear lower part of the main frame 9 of the mobile shelf, and are mounted with a lower damper 16. When the lower material blocking rod 17 is supported by the lower damper 16 in the natural state, the height at which it is located can block the materials on the lower complete inclined surface. When the mobile shelf 6 is lowered from top to bottom to connect with the fixed shelf 1, the lower pressing block 14 can push the lower material blocking rod 17 upward to the height position above the materials on the lower complete inclined surface, thereby releasing the materials on the lower complete inclined surface.

[0033] A pair of upper sliding shaft 11 components are provided, which are symmetrically arranged on the left and right sides of the upper ends of the main frames of the fixed shelf 1 and the mobile shelf 6. The pair of upper sliding shaft 11 components share an upper material stop rod 13, and the upper material stop rod 13 is mounted between a pair of upper dampers 12.

[0034] A pair of lower sliding shaft 15 components are provided, which are symmetrically arranged on the left and right sides of the lower ends of the main frames of the fixed shelf 1 and the mobile shelf 6. The pair of lower sliding shaft 15 components share a lower material stop rod 17, and the lower material stop rod 17 is mounted between the pair of lower sliding shafts 15.

[0035] The fixed shelf 1 and the movable shelf 6 are provided with an upper guardrail 18 and a lower guardrail 19 which are symmetrically arranged on the left and right, respectively, corresponding to the upper complete inclined surface and the lower complete inclined surface.

[0036] How to operate:

[0037] The mobile shelf 6 can be moved to the side of the fixed shelf 1 by the AGV, and then the mobile shelf 6 is placed between a pair of guide tubes 5 of the fixed shelf 1 from top to bottom, so that the rear end of the mobile shelf 6 is docked with the front end of the fixed shelf 1. During the docking process, in the upper sliding shaft 11 assembly, the upper pressing block 10 presses the upper material blocking rod 13 downward, and presses the upper material blocking rod 13 to be lower than the upper complete inclined surface without interfering with the sliding of the material. In the lower sliding shaft 15 assembly, the lower pressing block 14 pushes the lower material blocking rod 17 upward, and pushes the lower material blocking rod 17 to be higher than the material on the lower complete inclined surface without interfering with the sliding of the boring. After the docking is completed, the second feed roller group 7 on the upper layer of the mobile shelf 6 is connected with the first discharge roller group 2 on the upper layer of the fixed shelf 1, and the first feed roller group 3 on the lower layer of the fixed shelf 1 is connected with the second discharge roller group 8 on the lower layer of the mobile shelf 6. The materials on the second discharge roller group 8 on the lower layer of the mobile shelf 6 slide freely by their own weight and are transferred to the first feed roller group 3 on the lower layer of the fixed shelf 1. The empty boxes on the first discharge roller group 2 on the upper layer of the fixed shelf 1 slide freely by their own weight and are transferred to the second feed roller group 7 on the upper layer of the mobile shelf 6, thereby realizing the self-circulation of materials and completing the docking work.

[0038] The materials received at the lower level of the fixed shelf 1 are unloaded manually, and after unloading, the empty boxes are placed on the upper level of the fixed shelf 1 to be transported to the docked mobile shelf 6 for transportation.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
