Board piling apparatus

A board piling apparatus whereby the board delivered individually or in small bundles in a flatly laid-down state are raised up and collected in a lot and the collected boards are then turned about 90.degree. to form a pile of boards, characterized by incorporation of a board raising-up device comprisng a conveyor by which said boards delivered in a flatly laid-down state are received in the form as they are, a first lever pivotally supported at a position lower than the carriage surface of said conveyor, means for turning said first lever so that the first lever rises up above the carriage surface of said conveyor to lift up the leading end of the board and raise up the board on said conveyor and thereafter said first lever falls down below the carriage surface of said conveyor, a second lever pivotally supported at a position lower than the carriage surface of said conveyor, means for turning said second lever so that the second lever rises up above the carriage surface of said conveyor to lift up the trailing end of the board and raise up the board on said conveyor and thereafter said second lever falls down below the carriage surface of said conveyor, a board holding lever pivotally supported at a position below the carriage surface of said conveyor and slightly closer to the delivery end of said conveyor than the pivotted point of said second lever, and means for turning said board holding lever so that the board holding lever rises up above the carriage surface of said conveyor so as to hold the lower end of the board raised up by said second lever and thereafter said board holding lever falls down below the carriage surface of said conveyor.
