Description

Technical Field

[0001] This invention relates to the field of material storage and conveying in intelligent automated warehouses, specifically to a cargo storage and conveying device for intelligent automated warehouses. Background Technology

[0002] As a core piece of equipment for modern logistics automation and intelligence, automated storage and retrieval systems (AS / RS) have broad development prospects, especially driven by the rapid development of industries such as e-commerce, intelligent manufacturing, and pharmaceutical cold chain.

[0003] A Chinese invention with application publication number CN117533694 B discloses a material storage and conveying device for intelligent automated warehouses, including an installation shell, a U-shaped bracket, a conveying unit, a positioning and adsorption unit, an auxiliary support unit, and a control system.

[0004] However, the inventors discovered that while the device in the above invention transports goods via a conveying component, there is a distance between the conveying component and the shelf, making it impossible to transport the goods to the middle of the shelf. Based on this, the inventors proposed a goods storage and conveying device for intelligent automated warehouses. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by creating a cavity on the AGV (Automated Guided Vehicle) with a baffle flush with the AGV's upper surface. A first conveyor roller group and a second conveyor roller group are arranged within the cavity. A lifting assembly is located at the lower end of the first conveyor roller group, and guide assemblies are located on both sides of the second conveyor roller group. A support assembly, which abuts against the shelf, is located at the front end of the second conveyor roller group. A linkage assembly connects the first and second conveyor roller groups. In this invention, the lifting assembly raises the first conveyor roller group above the baffle, and the guide assemblies move the second conveyor roller group diagonally forward to above the baffle. The first and second conveyor roller groups are at the same horizontal level and transport goods forward. The support assembly connects the AGV to the shelf, providing a buffer when the AGV stops. This not only ensures the smooth movement of the goods but also allows the second conveyor roller group to transport goods to the center of the shelf, making storage and transportation of goods more stable.

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A cargo storage and conveying device for an intelligent automated warehouse includes an AGV (Automated Guided Vehicle) trolley. The AGV trolley has a cavity, and a baffle flush with the AGV trolley is mounted on the upper surface of the cavity. A first conveyor roller group and a second conveyor roller group are arranged within the cavity. A lifting assembly is located at the lower end of the first conveyor roller group, and guide assemblies are located on both sides of the second conveyor roller group. A support assembly that abuts against a shelf is located at the front end of the second conveyor roller group. A linkage assembly is provided between the first and second conveyor roller groups. The lifting assembly is used to lift the first conveyor roller group above the baffle, and the guide assemblies are used to move the second conveyor roller group diagonally forward above the baffle. The first and second conveyor roller groups are at the same horizontal height and convey goods forward.

[0008] As a preferred embodiment, the lifting assembly includes a first motor disposed at the lower end of the cavity, a rotating shaft driven by the first motor, a first gear disposed at both ends of the rotating shaft, a first rack meshing with the first gear, a first piston rod disposed at the end of the first rack, an oil pipe disposed at the lower end of the first conveying roller assembly, and a second piston rod slidably disposed at the other end of the oil pipe.

[0016] The beneficial effects of this invention are:

[0017] In this invention, the lifting component drives the first conveyor roller group to rise above the baffle, and the guiding component drives the second conveyor roller group to move diagonally forward to above the baffle. The first and second conveyor roller groups are at the same horizontal height and convey goods forward. The support component is used to connect the AGV trolley and the shelf, so that the AGV trolley can be buffered when it stops. This not only ensures that the goods are stable and not disturbed, but also that the second conveyor roller group moves diagonally forward, so that the goods can be conveyed to the middle of the shelf when conveying goods, making the storage and transportation of goods more stable.

[0018] In summary, this equipment has advantages such as stable transportation and more centrally positioned goods placement, making it particularly suitable for material storage and conveying in intelligent automated warehouses. Attached Figure Description

Detailed Implementation

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1

[0036] like Figures 1 to 13As shown, a cargo storage and conveying device for an intelligent automated warehouse includes an AGV trolley 1. The AGV trolley 1 has a cavity 2, and a baffle 3 flush with the AGV trolley 1 is mounted on the upper surface of the cavity 2. A first conveying roller group 4 and a second conveying roller group 5 are arranged inside the cavity 2. A lifting component 6 is provided at the lower end of the first conveying roller group 4. Guide components 7 are provided on both sides of the second conveying roller group 5. A support component 8 that abuts against a shelf is provided at the front end of the second conveying roller group 5. A linkage component 9 is provided between the first conveying roller group 4 and the second conveying roller group 5. The lifting component 6 is used to lift the first conveying roller group 4 above the baffle 3, and the guide components 7 are used to move the second conveying roller group 5 diagonally forward above the baffle 3. The first conveying roller group 4 and the second conveying roller group 5 are at the same horizontal height and convey goods forward.

[0037] It is worth mentioning here that, as Figures 5 to 6 As shown, the lifting assembly 6 includes a first motor 61 located at the lower end of the cavity 2, a rotating shaft 62 driven by the first motor 61, a first gear 63 located at both ends of the rotating shaft 62, a first rack 64 meshing with the first gear 63, a first piston rod 65 located at the end of the first rack 64, an oil pipe 66 located at the lower end of the first conveying roller group 4, and a second piston rod 67 slidably located at the other end of the oil pipe 66. In this invention, the first motor 61 drives the rotating shaft 62 to rotate, which in turn drives the first gear 63 to rotate, thereby driving the first rack 64 to move, driving the first piston rod 65 to squeeze the oil in the oil pipe 66, and pushing the second piston rod 67 to drive the first conveying roller group 4 to move upward.

[0038] In this embodiment, as Figure 7 As shown, the guide assembly 7 includes a column 71 disposed on the outer side of the second conveying roller group 5, a track groove 72 disposed at both ends of the second conveying roller group 5, a T-shaped block 73 disposed at the rear end of the second conveying roller group 5, a second gear 74 disposed in the middle of the rotating shaft 62, a second rack 75 meshing with the second gear 74, and a T-shaped groove 76 disposed at the end of the second rack 75. In this invention, the rotation of the second gear 74 drives the second rack 75 to move, and the T-shaped groove 76 pushes the column 71 on the second conveying assembly 5 to slide in the track groove 72, thereby driving the T-shaped block 73 to move upward in the T-shaped groove 76.

[0039] It needs to be emphasized that, such as Figures 8 to 10As shown, the support assembly 8 includes a fixed rod 81 disposed on the front end face of the second conveying roller group 5, an air bladder 82 disposed on the fixed rod 81, an air chamber 83 disposed at the lower end of the second conveying roller group 5, a third piston rod 84 slidably disposed within the air chamber 83, a first vent hole 85 disposed on the air chamber 83, a rotating sleeve 86 slidably disposed on the outer side of the air chamber 83, a hollow pipe 87 disposed on the inner wall of the rotating sleeve 86, a second vent hole 811 opened at the end of the hollow pipe 87, and an exhaust pipe 88 connected to the hollow pipe 87; fixed blocks 89 are disposed on both sides of the rear end of the second conveying roller group 5, and the inner side of the fixed blocks 89 is provided with a first vent hole 811. The first slide groove 810 is provided with the third piston rod 84 slidably disposed in the first slide groove 810. The exhaust pipe 88 is provided with a telescopic pipe at its end and is connected to the airbag 82. In this invention, when the second conveying roller group 5 moves, the fixed block 89 pushes the third piston rod 84 to move in the first slide groove 810 and pushes the third piston rod 84 to squeeze the air in the air chamber 83. The second conveying roller group 5 drives the rotating sleeve 87 to move forward. When the first vent hole 85 corresponds to the second vent hole 811, the air in the air chamber 83 flows to the airbag 82 through the hollow pipe 87 and the exhaust pipe 88, causing the airbag 82 to inflate. The AGV trolley 1 can be stably connected to the shelf.

[0040] It is worth mentioning here that, as Figure 11 As shown, the linkage component 9 includes a first belt 91 disposed between the first conveyor roller group 4 and the second conveyor roller group 5, a second slide groove 92 disposed on the side wall of the cavity 2, a slider 93 slidably disposed in the second slide groove 92, and a tension roller 94 rotatably disposed on the slider 93. In this invention, the second conveyor roller group 5 is driven away from the first conveyor roller group 4 by the guide component 7, and the first belt 91 drives the tension roller 94 to be on the same horizontal line as the first conveyor roller group 4 and the second conveyor roller group 5 during the straightening process.

[0041] In this embodiment, as Figure 3 As shown, a second belt 41 is provided on the end of the first conveyor roller group 4, a rectangular cavity 11 is provided on the side of the cavity 2, a second motor 42 is provided on the outer side of the first conveyor roller group 4, the second motor 42 is located in the rectangular cavity 11, a base plate 43 is fixedly provided at the lower end of the second motor 42, and the base plate 43 is slidably provided on the side wall of the rectangular cavity 11; a third belt 51 is provided at the end of the second conveyor roller group 5; in this invention, when the lifting component 6 drives the first conveyor roller group 4 to rise, it drives the base plate 43 to move upward on the side wall of the rectangular cavity 11, the second motor 42 moves upward, and drives the first conveyor roller group 4 to rotate.

[0042] In addition, such as Figure 3As shown, the ends of the conveying rollers on the first conveying roller group 4 and the second conveying roller group 5 are provided with first gear teeth, and the inner sides of the first belt 91, the second belt 41 and the third belt 51 are provided with second gear teeth that mesh with the first gear teeth. In this invention, the conveying rollers on the first conveying roller group 4 and the second conveying roller group 5 can be driven to rotate synchronously through the mutual meshing of the first gear teeth and the second gear teeth.

[0043] The work process is as follows:

[0044] Start the first motor 61, drive the rotating shaft 62 to rotate, drive the first gear 63 to rotate, and then drive the first rack 64 to move, drive the first piston rod 65 to squeeze the oil in the oil pipe 66, and push the second piston rod 67 to drive the first conveying roller group 4 to move upward.

[0045] When the rotating shaft 62 rotates, it synchronously drives the second gear 74 to rotate, which in turn drives the second rack 75 to move. The T-shaped slide 76 pushes the column 71 on the second conveying roller group 5 to slide in the track groove 72, which in turn drives the T-shaped block 73 to move upward in the T-shaped slide 76, and the second conveying roller group 5 moves obliquely upward.

[0046] When the second conveyor roller group 5 moves, the fixed block 89 pushes the third piston rod 84 to move in the first slide groove 810, and pushes the third piston rod 84 to squeeze the air in the air chamber 83. The second conveyor roller group 5 drives the rotating sleeve 86 to move forward. When the first vent hole 85 corresponds to the second vent hole 811, the air in the air chamber 83 flows to the air bag 82 through the hollow pipe 87 and the exhaust pipe 88, causing the air bag 82 to inflate. The AGV trolley 1 can be stably connected to the shelf.

[0047] Start the second motor 42 to drive the first conveyor roller group 4 to rotate. During the straightening process, the first belt 91 drives the tension roller 94 to be on the same horizontal line as the first conveyor roller group 4 and the second conveyor roller group 5. The first belt 91 drives the second conveyor roller group 5 to rotate synchronously.

That is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be understood as a limitation on the quantity.

[0049] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention.
