ABSTRACT:
A conveyor of the tilting tray type having the trays tiltable about an axis parallel to the moving direction for transverse unloading of conveyed articles at selected stations along the conveyor. Each of the trays is tiltably mounted on a carriage and has two rollers mounted at either end of a shaft secured to the tray transversely projecting to either side of the tilting axis. The rollers are respectively engaged with diametrically opposed surface portions of a disc member cranked so as to show a horizontal diameter section between respectively upwardly and downwardly slanting side portions, the disc member being mounted by the mid portion of the horizontal section on the upper end of a vertical drive shaft in such a position that the horizontal diameter section supports the rollers and thereby the tray in a locked horizontal position. The drive shaft is reciprocably rotatable about its axis when a radial member thereon abuttingly passes a selectively operable actuator rack displaced into the moving path of the radial member, whereby the horizontal disc section is turned away from its roller supporting position and by the slanting portions respectively urging one roller upwardly and allowing the other roller to move downwardly whereby the tray is tilted.
