Abstract
An apparatus for handling a plurality of lids or other thin objects having two discrete sides, such as a top and bottom, for delivering then in a common orientation includes a conveyor for carrying the lids along the apparatus from an inlet end to a discharge end and an air jet nozzle which directs compressed air to engage at least some of the lids to shift them to an opposing angle of inclination. The conveyor includes orienting belts which are directed over rollers and pulleys whereby the lids, after at least some have been shifted, are returned to a substantially horizontal position when delivered at the discharge end. Two sets of orienting bells are supported by the rollers and pulleys to effect a V-shaped support adjacent the air jet nozzle so that the lids are supported in either alternate opposing angle of repose. The air jet nozzle may alternatively operate continuously or be actuatable by an electric eye whereby discrete jets of air may be directed toward the lip of a lid to thereby orient it. A metering belt upstream of the conveyor serves to advance the lids individually to the conveyor. A pair of rotatable descrambling disks serve to separate the lids for handling by th…
