In actual production, as shown in fig. 1 to 3 and 5 to 7, when a production line behind the in-line carrier buffer device according to the present invention fails, the stopper 52 is lifted up by the fourth driving unit 51 so that the entire production line may not be stopped, and the carriers on the main flow line 2 cannot flow to the rear production line due to the influence of the stopper 52. First line 31 of keeping in with the stiff end of mainstream line 2 is the entry end, third line 33 of keeping in with the stiff end of mainstream line 2 is the exit end. At this time, the lifting structure 41 at the entrance end of the temporary storage line 3 works, specifically, the lifting portion 411 is lifted under the driving of the first driving portion 412 to contact the carrier and lift the carrier out of the first conveying device, and when the lifting portion 411 is higher than the second conveying device on the first temporary storage line 31, the horizontal pushing structure 42 at the entrance end of the temporary storage line 3 works. Specifically, the pushing portion 421 descends under the action of the first driving assembly 424, and the pushing portion 421 moves the carrier on the lifting portion 411 onto the first temporary storage line 31 under the action of the second driving assembly 422.
