An accumulation type conveyor turning mechanism

Abstract

Disclosed is a turnover mechanism of a power and free conveyor, comprising a machine body (1) and a number of trays (2), wherein front and rear ends of the machine body (1) are provided with sprockets (4) transmitted via a chain (3), each sprocket (4) is provided with a tangent wheel (7) on one side, the chain (3) is a double-row chain or a multiple-row chain, the chain (3) comprises a transmission row meshing with the sprockets (4) and a tray driving row extending to the outer side of circumferential surfaces of the tangent wheels (7), the bottom part of each tray (2) is provided with a tray base (21), a small sprocket (22) and a drive card (23) are mounted on the tray base (21), the tray driving row penetrates between the small sprocket (22) and the drive card (23), the small sprocket (22) is located on the outer side of the tray driving row and meshes with same, the drive card (23) is located on the inner side the tray driving row, and the drive card (23) comprises a tooth face (231) which can mesh with the tray driving row and a tangent face (232) which can be attached to the tangent wheel (7) under the action of the tray driving row and can rotate around the tangent wheel. The turnover mechanism of the power and free conveyor realizes turning over by providing the drive card and the tangent wheel, has a simple structure, has low costs of manufacturing, repairing and maintenance, is easy to maintain and has a stable performance, and at the same time the jamming phenomenon during the turning over of the trays is effectively avoided.

Description

technical field [0001] The invention is used in the technical field of accumulation type conveying, and in particular relates to an overturning mechanism of an accumulation type conveyor. Background technique [0002] In the automobile body-in-white welding workshop, in order to improve product quality, reduce labor intensity, ensure worker safety, and improve automation production efficiency, it is very necessary to provide reliable highly automated flexible equipment that can support model changes. As a result, major automobile factories around the world are competing to adopt highly automated multi-robot flexible welding systems for their own development needs. With the popularity of robotic flexible welding systems, various conveying equipment for assisting robots to complete automobile body-in-white welding has emerged as the times require. [0003] At present, there are more or less technical defects in the overturning mechanism of the existing accumulation type convey...
