Abstract: A conveying device including a frame, a transportation channel, and a branch conveying mechanism, the transportation channel and the branch conveying mechanism are driven by their respective driving units, and the transportation channel is provided with a number of rows of regular rollers, or at least a conveyor belt, or a combination of regular rollers and a conveyor belt, the branch conveying mechanism includes at least one group of irregular rollers, when the irregular roller rotates, the highest point of a top of the roller is higher than an upper surface of an adjacent transportation channel during the rotation, and the lowest place of a top horizontal plane of the roller is lower than the upper surface of the adjacent transportation channel; when the irregular roller does not rotate, the top of the roller substantially stops at the lowest place of the top horizontal plane of the roller during rotation; the transportation channel and the branch conveying mechanism are provided alternately.

Abstract: A sorting module including two groups of transportation rollers, the two groups of transportation rollers include at least one group of irregular rollers, the other group of transportation rollers are regular rollers or irregular rollers, each group of transportation rollers include at least one row of transportation rollers, each row of transportation rollers include at least one transportation roller; the rotation center lines of each row of transportation rollers are on one straight line, and the rotation center lines of the two groups of transportation rollers are generally perpendicular to each other. A conveying device including the sorting module is simple in structure and low cost.
