[0045] In the logistics industry, goods need to be transported between warehouses and transport vehicles. In the traditional way, the transportation of goods is completed by manual labor, but manual transportation is high in cost and low in efficiency. With the continuous development of automatic equipment, some automatic loading and unloading equipment has been gradually applied to the loading and unloading of goods in the logistics industry, which reduces the labor cost.

[0046] In the related art, the automatic loading and unloading equipment includes a mechanical hand for loading and unloading goods and a conveying line for conveying goods, the mechanical hand picks up goods from the stacked goods and places them on the conveying line, and the conveying line conveys the goods to the designated position.

[0047] However, in the process of transferring goods by the mechanical hand, the distance of the goods to be moved by the mechanical hand gradually becomes farther from the conveying line, the moving stroke becomes longer, and thus the loading and unloading efficiency of the goods is low.

[0048] In order to improve the loading and unloading efficiency of the goods, a movable conveying device and a loading and unloading vehicle robot are provided, and the scheme provided by the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0051] As Figure 2 shown, when the robot does not take goods, the conveying assembly 300 is located on the chassis 300 as a whole. Referring to Figure 3 , when the robot takes goods, the driving assembly 400 drives the conveying assembly 300 to approach the goods synchronously with the robot, the conveying assembly 300 extends from the chassis 100, so that the movement stroke of the robot for grabbing goods and placing the goods on the conveying assembly 300 is greatly shortened, and the efficiency of taking and placing goods is improved. When the robot grabs the next piece of goods, the driving assembly 400 simultaneously drives the conveying assembly 300 to move away from the goods, so as to butt joint the conveying assembly 300 with the conveying line, so that the goods can be conveyed to a designated position through the conveying line. Then, the driving assembly 400 drives the conveying assembly 300 to move towards the goods again, so as to take the next piece of goods grabbed by the robot. It can be understood that the conveying assembly 300 reciprocates between the goods and the conveying line, greatly shortens the movement stroke of the robot, and makes the grabbing and conveying processes of two adjacent goods overlap in time, so as to improve the frequency of loading and unloading goods, thereby greatly improving the efficiency of loading and unloading goods.

Among them, the first conveying part 310 and the third conveying part 330 are respectively configured as a conveying belt assembly or a conveying roller assembly for conveying goods. The second conveying part 320 can be configured as a transfer conveying assembly arranged at the corner of the first conveying part 310 and the third conveying part 330 to change the conveying direction of the goods. The conveying belt assembly, the conveying roller assembly or the transfer conveying assembly are all prior art, and will not be described here.
