<p>A hold and release singulator (33) includes a conveyor having a transport mechanism (306) for carrying a group of items such as parcels, packages, containers or the like (64) from an entry end towards an exit end of the singulator (33). The singulator (33) is part of a system that can hold items that have entered the singulator (33) on the conveyor so that such items are not transported by the conveyor while causing one item to be transported by the conveyor. A control system controls the operation of the conveyor and the system in a manner effective to remove the group of items from the exit end of the conveyor one at a time according to a removal scheme, preferably with a predetermined minimum spacing. The system can take several forms such as a mechanism for selectively actuating a portion of the conveyor or a mechanism for lifting items off the conveyor surface.</p> |
