Piece Turning Apparatus For Selectively Turning Elongated Pieces of Lumber Carried in Sequence By a Conveyor

摘要

A system for selectively turning elongated pieces comprising a conveyor transversally receiving and carrying in a sequence the elongated pieces along a transfer course. A piece turning apparatus is mounted next to the conveyor and has a number of turning hands in which an end of one of the elongated pieces is engageable so that rotation of the turning hand effects a turning of the one of the elongated pieces about a longitudinal axis thereof when the end of the one of the elongated pieces is engaged in the turning hand. Carriages are distributively mounted onto the endless driving body and supporting respectively the turning hands so that each one of the turning hands successively moves into an engaging position with an end of one of the elongated pieces as the one of the elongated pieces is carried by the conveyor. A cam body drives the turning hands in rotation.
