Abstract
Abstract A veneer sorting and stacking apparatus for segregating randomly sized veneer sheets, including both relatively wide sheets of selected predetermined dimensions as well as narrower width strips of variable dimension, into a plurality of stacks of respectively uniform characteristics. A main conveyor system delivers transversely arranged unsegregated veneer sheets of random and variable sheet widths horizontally at spaced intervals to the top of the proper respective sorting bin where a diverter roller triggered by width and moisture detecting devices along the path of the conveyor diverts each sheet downwardly into the sheet positioning apparatus of the bin. The sheet positioning apparatus comprises a vacuum conveyor system which retains each sheet by its upper surface and transports it downwardly on an inclined path towards the stack supporting surface of a lift table until a kicker arm separates the respective sheet from the vacuum conveyor, allowing the leading edge of the sheet to drop into abutment with a fixed transverse aligning stop and settle horizontally onto the top of the stack in formation. An aligning clamp immediately seizes the leading edge of the sheet to prevent it from bouncing off of the aligning stop, and thereafter is released prior to the placement of the next succeeding sheet. As the stack reaches a predetermined height with respect to the face of the aligning stop, the lift moves downward in measured increments until a completed stack of predetermined height or count is reached, whereupon the stack may then be removed from its bin by powered rolls or other transporting means. In those of the bins which are intended for stacking variable-sized and generally narrow width veneer strips the vacuum conveyor system for these bins comprises two separate vacuum conveyors, one inclined downwardly from the top center of the bin toward a front aligning stop adjacent the leading transverse edge of the stack and the other inclined in opposite relation toward a rear aligning stop adjacent the rear transverse edge of the stack. Means are provided for alternating the transfer of successive strips from the main conveyor to one or the other of the two vacuum conveyors so as to enable the formation of a uniform stack substantially wider than that of the largest width of veneer strip sorted into the bind. The vacuum conveyor systems handling strip material are also provided with actuable diverter arms at the top center of the bins to divert veneer strips of especially narrow width into the center of the stack.
