Abstract
Apparatus and method for centering logs and veneer blocks by determining the largest inscribed cylinder that the veneer block can contain. Sensors located along the log length measure the critical dimensions and feed their measurements into a computer circuit for determining in less than a minute, the proper end centers of the log under examination for the maximum dimension of the cylinder which can be obtained from the log in veneering operations. The sensing elements may also be optical or accoustical, and thus avoid direct contact with the log surface.
Claims11
A centering device for logs for veneer processing, comprising supporting means for supporting a log in said centering device, sensing means for sensing the surface contour of said log at a plurality of locations along its length and also between its ends, said log having first and second end surfaces and a stem portion therebetween, and computer means for processing the observations of said sensing means to compute the proper end centers of said log under examination for the maximum dimension of the cylinder which can be obtained from said log in veneering operations.
