Abstract

An apparatus for selectively routing articles from a supply conveyor belt to an upper delivery conveyor and a lower delivery conveyor. The apparatus has first, second and third deflecting rollers about which the supply conveyor belt is successively trained. The first and second deflecting rollers are at about the same height level, while the third deflecting roller is therebelow. The first deflecting roller defines a first discharge end and an upper reach, while the third deflecting roller defines a second discharge end and a lower reach of the supply conveyor belt. The first deflecting roller can assume an advanced position in which articles advanced on the upper reach are transferred from the first discharge end onto the upper delivery conveyor and a withdrawn position in which articles advanced on the upper reach are transferred from the first discharge end onto the lower reach. The third deflecting roller can assume an upper position in which the lower reach extends approximately parallel to the upper reach and a lower position in which the lower reach slopes downwardly to the lower delivery conveyor and in which articles advanced on the lower reach are transferred from the sec…
