<p>The invention relates to a grading/sorting device for a return machine for empty containers, preferably in the form of deposit bottles (2, 3) and, possibly, cans, said containers (2, 3) being intended to be inserted into and conveyed forwardly within an insertion and transport pipe (4, 4'), in which an air flow can be established by means of at least one fan (7). One has aimed at providing an efficient and reliable grading/sorting of two or more different container sizes. This is achieved in that said insertion and transport pipe (4, 4'), within a downstream area, is formed with at least one substantially downwardly facing opening (4a), which is shaped in order to slip through one smaller container size (2) only.</p> |
