Conveyor path with buffer arrangement

摘要

The conveyor has goods unit travel path (4) consisting of a series of support rollers (2). On one or more points of the path are located lift elements movable from lower rest position in a top working one. The elements are swivelable bars (7), whose swivel axes (11) parallel to the support roller rotation axes (18). They lie between the support rollers. The sides (10) of the bars, facing the travel path, are eccentric w.r.t. the geometrical swivel axes. During a swivel motion, they can be shifted from the rest position under the travel path into the working position over the travel path of the goods unit (3).
