ABSTRACT:
In a device for toppling articles of at least approximately rectangular outline while conveying such articles, which device includes a discharge path provided with carrier elements for moving the articles after toppling in a discharge direction lying in the plane of their outlines, at least two input paths are provided above the discharge path for conveying such articles in an input direction transverse to the discharge direction, with the plane of the outline of each article perpendicular to the input direction and the larger outline dimension of each article vertical, and a plurality of lowering and toppling mechanisms are provided, each mechanism being associated with a respective input path and disposed for transferring articles from its associated input path to the discharge path while lowering and toppling the articles, each mechanism including a supporting element movable between a position for supporting articles received from the associated input path and a release position for permitting such articles to drop, a pickup element for supporting and lowering such articles when the supporting element is moved to its release position, and a toppling element movable from a starting position for toppling such articles onto the discharge path upon lowering of such articles by the pickup element, so that the smaller outline dimension of each such article is verticle on the discharge path.
