Abstract
A workpiece is aligned in the X, Y coordinate plane at a predetermined X, Y reference coordinate. Separate X and Y coordinate transports rapidly transport and align the workpiece. Deceleration means prevent the workpiece from slipping on the work surface. An adjustable, stationary workpiece engaging plate speeds the cycle time of the device by providing dual coordinate alignment of the workpiece. Sensors are provided to detect the presence of a workpiece properly aligned in the X, Y coordinate plane. The sensors may be either individually connected or coupled through a control means to previous and succeeding workstations in such a manner that the invention can interrupt the 'fault chain' that occurs when a workpiece becomes fouled along the assembly line.
