ABSTRACT:
A device for the translation or discharge of articles from a transport conveyor to a discharge conveyor includes a push-off ledge that is moveable into the transport conveyor path. The elongated push-off ledge is pivoted at each of its ends to an endless pull member that is guidely driven around a start-deflection roller, an out-deflection roller and a displaceably-tensioned guide roller that are rotatable about vertical roller shafts. Each of the pair of pull members are synchronously driven so that the push-off ledge remains substantially parallel to the conveyor's article transport direction while the ledge is advanced, for displacing an article from the transport to the discharge conveyor, at an oblique angle to the article transport direction. The push-off ledge is retracted substantially perpendicular to the transport direction, thereby avoiding interference with following articles being carried on the transport conveyor.
