Abstract
An apparatus for detecting a pallet full load state determines a pallet full load state while switching the upper limit value of the mounting height of workpieces according to workpiece size. The controller of an apparatus for controlling a sheet metal machining line estimates an occurrence or non-occurance of a pallet full load state. A pallet full load state is defined as a function of the overall height or the total weight of the workpieces loaded on the carrier pallet. The controller estimates an occurance or non-occurance of a pallet full load state by analyzing the machining schedule when a machined workpiece is loaded on the carrier pallet has a replacing carrier pallet suitable for the next workpiece to be loaded standby whenever appropriate.
