Description

Technical Field

[0001] The present invention relates to the technical field of logistics warehousing and transportation equipment, and specifically to an AGV cart for automatic loading and unloading of goods. Background Art

[0002] An Automated Guided Vehicle (AGV), commonly known as an AGV cart, refers to a transport vehicle equipped with an automatic guidance device such as electromagnetic or optical means. It can travel along a specified guidance path and has functions such as safety protection and various transplanting functions. In application, the AGV cart does not require a driver and uses a rechargeable battery as the power source. Compared with other commonly used equipment for materials, the working area of the AGV does not need to be paved with fixed devices such as tracks and brackets, and is not restricted by the site, roads, and space.

[0003] At present, the path control of AGV carts has become increasingly mature, but the automatic loading and unloading function of AGV carts for goods is not yet perfect. The Chinese patent "An Automatic Loading and Unloading Device for an AGV Cart" (Publication No. CN208360011U) sets a swinging motion mechanism and a storage tray on the chassis of the AGV cart. The swing rod is driven by a motor to drive the storage tray to tilt to both sides, overcoming the technical defect that the AGV cart cannot dump from both sides to facilitate loading and unloading of goods. The mechanism adopted is relatively simple and easy to implement, but this patent cannot achieve the autonomous loading and unloading of goods and cannot achieve the complete automation of the AGV cart.

[0004] The Chinese patent "An AGV Cart with Freely Rotatable Automatic Loading and Unloading of Goods" (Publication No. CN208814077U) sets a cargo loading and unloading mechanism on the upper side of the vehicle body. There are a total of three panels, which are connected by electric telescopic rods. A turntable is installed at the bottom of the support plate, and the upper side of the vehicle body can be freely rotated through the turntable. This patent realizes the functions of automatic loading, transporting, and unloading of goods through the freely rotatable cargo loading and unloading device, but its structure is too complex, resulting in slower speeds for autonomous loading and unloading, and it cannot achieve real-time unloading of the cart, which will cause uneven speeds during the driving process of the cart. Summary of the Invention

[0005] The purpose of the present invention is to provide an AGV cart for automatic loading and unloading of goods, which can achieve automatic loading, transporting, and unloading of goods and improve work efficiency.

[0006] The technical solution adopted by the present invention to solve its technical problems is:

[0007] An AGV cart for automatic loading and unloading of goods, comprising a vehicle body, with front wheels and rear wheels provided at the bottom of the vehicle body, and a loading platform at the top of the vehicle body. The loading platform has a downward slope on one side of the front wheels, and a semi-circular goods baffle is provided on one side of the loading platform where the rear wheels are located; a goods conveyor belt is provided on the slope, and a forklift is provided at the outer end of the slope, and the forklift can be turned upwards; the loading platform is also provided with a horizontal first goods conveyor belt and a second goods conveyor belt at intervals, the directions of the two goods conveyor belts are the same as that of the goods conveyor belt, and a vertical rotating baffle is provided between the two goods conveyor belts, and the rotating baffle is driven by a first motor provided at the bottom of the vehicle body.

[0008] Further, the forklift is provided with a horizontal rotating shaft, a second motor is provided at the bottom of the vehicle body, sprockets are respectively provided on the output shaft of the second motor and the horizontal rotating shaft, and a meshing chain is sleeved between the two sprockets to form a cooperation.

[0009] The beneficial effects of the present invention are that the goods are lifted by the forklift turning over, and then the goods are transported to the loading platform through the cooperation of the goods conveyor belt, the rotating baffle, the first goods conveyor belt and the second goods conveyor belt, realizing the autonomous loading and unloading of goods. Not only is it more convenient to load goods, and manual loading and unloading of goods is not required, thus improving work efficiency; the goods baffle can prevent the goods from falling during the transportation process and prevent the goods from being damaged.

[0016] Combined with Figure 1 and Figure 2As shown in the figure, the present invention provides an AGV cart for automatically loading and unloading goods, which includes a vehicle body 1. The bottom of the vehicle body 1 is provided with a front wheel 2 and a rear wheel 3. The top of the vehicle body 1 is a loading platform 4. One side of the loading platform 4 located in front of the front wheel 2 is a downward slope 4a. One side of the loading platform 4 located behind the rear wheel is provided with a semi-circular goods baffle 5. A goods conveyor belt 6 is provided on the slope 4a, and a forklift 7 is provided at the outer end of the slope 4a. The forklift 7 can be turned upwards. The loading platform is also provided with a horizontal first goods conveyor belt 8 and a second goods conveyor belt 9 at intervals. The first goods conveyor belt 8 and the second goods conveyor belt 9 are respectively located on the left and right sides, and the directions of the two goods conveyor belts are the same as that of the goods conveyor belt 6. Combined with Figure 3 As shown in the figure, a vertical rotating baffle 10 is provided between the two goods conveyor belts. The rotating baffle 10 is driven by a first motor 11 provided at the bottom of the vehicle body. The first motor 11 and the rotating baffle 10 are connected by a drive shaft 12 in a shaft connection.

[0017] Combined with Figure 4 As shown in the figure, the forklift 7 is provided with a horizontal rotating shaft 13. A second motor 14 is provided at the bottom of the vehicle body. A first sprocket 15 and a second sprocket 16 are respectively provided on the output shaft of the second motor 14 and the horizontal rotating shaft 13. A meshing chain 17 is sleeved between the two sprockets to form a cooperation.

[0018] Combined with Figure 5 As shown in the figure, taking the first goods conveyor belt 8 as an example, the first goods conveyor belt includes a third motor 18 horizontally provided at the bottom of the vehicle body and a group of conveying rollers 19. The same-side ends of the third motor 18 and the conveying rollers 19 are respectively connected with pulley wheels 20. A belt 21 for forming a transmission cooperation is sleeved on the outer periphery of the pulley wheels 20. A conveyor belt 22 is sleeved on the outer periphery of the conveying rollers 19.

[0019] During use, the following steps can be carried out:

[0020] When loading goods, first the forklift 7 forks the goods. After the second motor 14 is started, the horizontal rotating shaft 13 is driven to rotate through sprocket transmission, and the forklift 7 turns upwards, so that the goods fall on the goods conveyor belt 6 on the slope 4a. The goods conveyor belt 6 transports the goods upwards towards the loading platform. At the same time, the first motor 11 is started, and the rotating baffle 10 starts to rotate to assist in dialing the goods onto the loading platform. Then the goods conveyor belt is started to transport the goods to the inner side of the loading platform. Then the AGV cart can start to transport. During transportation, the goods baffle 5 can prevent the goods from falling during the transportation process and prevent the goods from being damaged. When unloading goods, the process is opposite to that of loading, which will not be elaborated here.

[0021] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into equivalent embodiments with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of protection of the technical solution of the present invention.
