Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to an AGV trolley unloading conveyor line. Background Technology

[0002] Automated Guided Vehicles (AGVs), also known as automated guided vehicles or automated guided transport vehicles, are industrial vehicles that load goods automatically or manually, automatically travel along a set route or pull a cargo trolley to a designated location, and then load and unload goods automatically or manually.

[0003] Currently, our company uses AGVs to transport materials, parts, and products. In particular, the boom boxes on the skid steer loaders are placed in the transfer frame after assembly and welding, and then transported to the conveyor line outside the factory by AGVs. Forklifts are used to unload the transfer frame onto the AGVs, and the goods are ready to be packaged and shipped to customers. However, unloading still relies on forklifts and forklift drivers, which is labor-intensive and cannot truly achieve unmanned operation. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0027] This embodiment is designed to meet the unloading needs of AGV trolleys with lifting structures:

[0028] An AGV (Automated Guided Vehicle) unloading and conveying line includes a main frame 1 and a support frame 2. Two support frames 2 are fixedly arranged side by side on one side of the main frame 1. The two support frames 2 and the main frame 1 are arranged in a U-shape. The recess between the two support frames 2 forms a workstation 3 for parking AGVs. This workstation 3 facilitates the entry and parking of AGVs. Then, a lifting AGV can place a shelf with a width greater than the width of the workstation on the support frame. No driver or forklift is required, reducing labor and improving the level of unmanned operation.

[0029] It should be noted that, for the convenience of conveying, a number of first support rollers 4 are arranged in parallel at intervals along the conveying direction on the upper end face of the support frame 2, and the first support rollers 4 are connected to the support frame 2 in a rotating manner; a number of second support rollers 5 are arranged in parallel at intervals along the conveying direction on the upper end face of the main frame 1, and the second support rollers 5 are connected to the main frame 1 in a rotating manner.

[0030] Two adjacent first support rollers 4 are connected by a sprocket drive structure 6, and two adjacent first support rollers 4 and second support rollers 5 are connected by a sprocket drive structure 6. By setting the sprocket drive structure 6, a large amount of power is provided for the rotation of the first support rollers 4 and the second support rollers 5, which can meet the needs of conveying heavy objects.

[0031] It should be noted that the first support roller 4 is connected to the bearing frame 2 through a bearing seat, and the second support roller 5 is connected to the main frame 1 through a bearing seat, which facilitates the smooth rotation of the first support roller 4 and the second support roller 5.

[0032] It should be noted that the upper edge of the first support roller 4 protrudes from the upper surface of the main frame 1, and the upper edge of the second support roller 5 protrudes from the upper surface of the main frame 1, which facilitates the transfer of the shelf with a flat bottom structure.

[0033] Specifically, the sprocket drive structure 6 includes a sprocket 61 and a chain 62. The sprocket 61 is connected to the first support roller 4 and the second support roller 5 via a key. It should be noted that, except for the outermost first support roller 4 which is connected to a sprocket 61, the outer sides of the other parts of the first support roller 4 and the second support roller 5 are each provided with two parallel sprockets 61. In this way, two adjacent sprockets 61 along the conveying direction are connected by the meshing of the chain 62.

[0034] Furthermore, the main frame 1 is fixedly equipped with a power component A for driving the sprocket transmission structure 6 to rotate. The power component A is a geared motor. The output end of the geared motor is connected to a drive sprocket via a key. The drive sprocket is connected to the outermost sprocket of the main frame via a chain, providing power to the entire sprocket transmission structure 6.

[0035] To ensure safety, the main frame 1 and the support frame 2 outside the sprocket drive structure 6 are fixedly equipped with protective covers 7.

[0036] In addition to the above embodiments, in another embodiment, to meet the unloading needs of AGV trolleys without lifting structures:

[0037] Each of the two support frames 2 has a pair of scissor jacks 8 on one side opposite to each other. The input ends of the two scissor jacks 8 on the same side are connected by a connecting rod 9. It should be noted that the screws of the two scissor jacks 8 and the connecting rod 9 rotate concentrically at the same time. The output shaft of the scissor jacks 8 inside is connected to a power component B. The power component B is connected to the main frame 1 or the support frame 2 in a fixed structure. The power component B is a geared motor, which is fixedly connected to the main frame 1.

[0038] It should be noted that the inner side of the scissor jack 8 is equipped with a guardrail 10 that is connected to the main frame 1 and the support frame 2 to prevent the scissor jack 8 from being touched and affecting its lifting and lowering.

[0039] The working principle and process of this utility model are explained below using the unloading of an AGV trolley without a lifting structure:

[0040] First, the AGV trolley carrying the bucket box shelf is parked in the workstation. Then, power component B is started. Power component B drives the screw of one scissor jack 8 to rotate. This screw drives the screw of another scissor jack 8 to rotate through the connecting rod 9, thereby causing the scissor jack 8 to rise until it lifts the shelf away from the AGV trolley. Then, the AGV trolley drives away from the workstation. Then, power component B is rotated in the opposite direction to lower the scissor jack 8 until the shelf lands on the first support roller 4. Then, power component A is started. Power component A drives the first support roller 4 and the second support roller 5 to rotate through the sprocket transmission structure 6, transferring the shelf carrying the bucket box to the designated position.
