摘要 1,129,070. Hoppers; conveyers. RAYONIER Inc. 24 May, 1967 [30 Aug., 1966], No, 24143/67. Headings B8A and B8S. Each of a number of accumulator bins B, for receiving lumber L of a certain Specification, has an open top and a curved, semicylindrical bottom 10 and mechanical power-driven means to oscillate the bin B periodically to arrange in an orderly group lumber L dropped in the bin B, and means to turn the bin B over, when it has become filled, to dump the load. As shown lumber L in the form of boards from a sawmill is delivered by a conveyer 7 to a more rapidly travelling conveyer 8 which pushes the boards into the open ends of pendant hangers P on a drop-out conveyer system 4 comprising a parallel chain conveyer 5. Thirty or forty (five only shown) bins B are mounted on a base consisting of two I-beams 1, 2 supported on steel columns C above a conveyer 3. A board rakeoff device 50 is associated with each bin B and comprises an air-operated piston rod 51 which turns a bell-crank 52 which, when extended downwardly, engages the moving board and rakes it off the hanger P. When a bin B is inverted to discharge its load operation of its rake-off device 50 is blocked and a board intended for that bin is re-circulated to the conveyer 7. The lumber L may be fed by hand to the bins or may be classified by an operator operating a switch which sets an actuating means on the hanger P of that board which causes the board to be released at a particular bin B. An arrangement of photo-electric cells can be provided to cause boards having a certain length and width and/or grade to be released into a particular bin B.
