Abstract
A workpiece manipulating apparatus for faceplate panels of cathode ray tubes includes a conveyor for carrying panels along two groups of grinder stations in a pattern coordinated with carriage mounted loaders which move along the conveyor. The conveyor indexes to loading stations as do the loaders. Unground panels are sequenced to the stations as the loaders are present. Loaders pick the unground panels from the conveyor and transfer them to an orienting station which orients panels for loading into a grinder. Loaders pick an oriented panel from the orienting station and load it in to the grinder at the loading station. They also picks up ground panels from the grinder and place them in a reorient station and picks ground panels from the reorient station and places them on the conveyor in the position from which they removed an unground panel. The loader advances to a next loading station to load a next grinder and the conveyor with panels picked up at the preceeding station. The cycle is continuous with the panel manipulation through a complete cycle approximating the grinding time of a panel in a grinder.
