Abstract
A conveying system has at least two equidistant conveyor chains. In order that the chain links of the conveyor chains also move synchronously on conveying path portions in which the radii of curvature of the individual chain paths differ from one another, the chain link spacings can be adapted by corresponding control means to the ratio of the radii of curvature of the individual chain paths.
Claims7
A conveying system comprising the combination of at least two chains bordering a conveying path in generally parallel relationship, each said chain having a plurality of links;
- connecting means for connecting each said link of a chain to a link of at least one other chain;
- a plurality of controllable coupling members, one said coupling member being positioned between successive links of one said chain, said coupling member being movable between an active state in which said successive links are connected together and an inactive state in which said links are unconnected;
- and control means for moving said coupling members between said active and inactive states whereby said successive links selectively are held in a predetermined spacing relationship or are allowed to move relative to each other, allowing the chains to adapt to changes in direction of the conveying path.
