Roller way conveying buffer segment

Abstract

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.

Description

technical field [0001] The invention relates to a roller conveying buffer section for continuously conveying articles without gaps (less gaps). The roller conveying buffer section can be widely used in various industries as a part of roller conveying equipment. Background technique [0002] In the past, in roller conveying, items often run at high speed in the long-distance (or non-working stroke) conveying area. When the items reach the working area, they must be fed at a slow speed (or working speed). After going out of the work area, it is necessary to leave the work area quickly and arrive at the destination. In this way, the item has gone through the conversion process from fast to slow and from slow to fast. In such a process, if it is not handled properly, when the speed changes from fast to slow, the following items will hit the front items, so that the transport of the items cannot be carried out smoothly, or bumps and scratches will occur between the items, thus a...

Problems solved by technology

In such a process, if it is not handled properly, when the speed changes from fast to slow, the following items will hit the front items, so that the transport of the items cannot be carried out smoothly, or bumps and scratches will occur between the items, thus affecting the appearance of the items (products). Quality; or the gap between the front and rear items is too large, which affects the conveying capacity and productivity; in addition, near the fast and slow alternating section, due to the difference in speed, sliding friction may occur on the contact surface between the item and the idler roller, thus affecting the idler roller and transmission, power device life, especially for heavy items, this effect is more obvious
