ABSTRACT:
A log charging apparatus for a veneer production line. A log to be peeled is supported in a non rotative manner at a scanning station. The log is scanned and the scan data is input to a computing device to determine an optimum cylinder of the log and to determine the longitudinal axis of the optimum cylinder. Grip points relative to the axis of the optimum cylinder are determined for each end of the log. The log is transferred to the peeling lathe by a transfer mechanism that grips the log at the established grip points and aligns the longitudinal axis of the optimum cylinder with the rotational axis of the opposed spindles of the lathe. The transfer mechanism includes a movable carriage mounted on pivotable main support arms. The main support arms are pivotally movable to and from the scanning station and to and from the peeling lathe. A gripping arm having gripping pads is pivotally mounted on the carriage to facilitate gripping the log at the defined grip points and to facilitate aligning the axis of the optimum cylinder of the log with the axis of the opposed spindles of the peeling lathe.
