Abstract: An assembly for transfer of roller chain link-plates between operations of a high-rate manufacturing process includes rapid, repeatable and reliable transfer apparatus; tooling for grasping the link-plates without disturbing the advancing link-plates from the completed operation, which grasping-tooling is operable with the transfer apparatus; parts-feeding assemblies for receipt of transferred link-plates; and, a control system with a central processing unit (CPU) and a plurality of sensors, which sensors are coupled between the transfer apparatus, the grasping-tooling, the feeder assembly, the manufacturing equipment and the CPU for communication of control signals to the CPU as well as synchronous control of the several manufacturing operations and the transfer assembly.

Abstract: A veneer lathe charging apparatus includes a break-beam scanning system and a computer for determining an optimal log spin axis. The charging apparatus further includes charger arms independently operable and adjustable to transfer a log from a scanning station to a veneer lathe so that a predetermined spin axis is precisely aligned in the chucks of a veneer lathe. Additionally, there is provided an extendible-retractable spindle assembly operable for rotating a log during scanning.

Abstract: A system for detecting offsize defects and for segregating the veneer sheets containing the defects from the non-defective sheets. Scanners are positioned along the in-feed conveyor leading to the clipper. As offsize defects are identified, a computer determines which of the sheets to be cut will contain the defects. These sheets are segregated as by diverting them to a pull chain conveyor following the cutting of the sheets from the continuous sheeting. Dye is sprayed on the area of the defects as detected by the scanners to aid in further handling of the defective sheets when removed from the pull chain.

Abstract: A system that rotatively orients and skew positions a log for lumber processing. A log is placed in centering V's and rough centered. Rotatable scan spindles rotate the log while scanners obtain measurements at spaced locations along the log length and at selected rotative positions. Each angular position is analyzed for an optimum cutting pattern and the spindles are rotated to rotate the log into the most desirable angular position. The log is skew adjusted by the scan spindles and/or knee clamps in a carriage and conveyed to a saw array. A computer controls the cutting action to achieve the selected cutting pattern.

Abstract: Centering a log by determining the location of a selected axis through the log relative to a fixed replicate axis. The log is pinned and each end is provided with double pivots. Pivoting the log about one pivotal axis spaced from the replicate axis determines a pathway around that axis. Pivoting the log about the other pivotal axis sweeps the log end and, accordingly, the selected axis across the determined pathway. The selected axis is positioned on the pathway by pivoting the log about said other axis and it is positioned at the replicate axis by pivoting the log about the first pivotal axis.
