A method for counting and aggregating a pre-determined number of articles includes: driving, by a conveyor, an article stream to move to an end of the conveyor in a single layer state; conveying the article stream in a periodic motion; after the articles in the article stream leave the conveyor, accurately counting the number of the articles; and when a total number of articles in a combination of temporary storage bin is the same as a target number, transporting all articles in the combination of temporary storage bin to a storage device. Article batches are separately delivered to different temporary storage bins, and the total number of articles in temporary storage bins in different combinations is calculated, so as to obtain with a combination in which the number of articles is the same as the target number. The operation efficiency is improved and the manufacturing cost of device is reduced.
