Roller way conveying buffer segment

The invention provides a novel roller table conveying buffer segment for high-low speed switching, which aims at the process requirements on roller table conveying that an article at the back needs to catch up with another article in the front. The roller table conveying buffer segment comprises a fast speed zone, a buffer zone and a slow speed zone, wherein the fast speed zone is provided with a carrying roller and a fast speed zone motor reducer; the buffer zone is provided with a carrying roller, an overrunning clutch and a position transducer; and the slow speed is provided with a carrying roller and a slow speed zone motor reducer, wherein when the articles enter the buffer zone from the fast speed zone, the fast speed zone motor reducer slows down according to a signal from the position transducer in the buffer zone, and the carrying roller in the buffer zone is changed into a driven carrying roller by the overrunning clutch. When the novel roller table conveying buffer segment is used for continuous zero clearance (little clearance) conveying of various articles with high-low speed switching, the sliding friction between the articles and the contacting surfaces of the carrying rollers and the bumping among the articles are reduced, and the adjacent articles can be effectively contacted.
