Abstract
A log singulator and associated method for conveying and controllably discharging logs are provided. The singulator has a plurality of rotatable lifters with outwardly-extending arm members that contact the logs with a leading side to convey the logs to successive positions, for example, along a log cradle structure. The logs are conveyed to a discharge surface, which can be disposed at a declined angle so that the logs thereon tend to roll toward a discharge position. Discharge lifters, which are configured to discharge the logs from the discharge surface, have arm members that define angled cam surfaces on their trailing sides. The cam surfaces contact and retain the logs on the discharge surface until the logs reach the predetermined discharge position. Thus, the logs can be controllably discharged, for example, at a desired time.
