Conveyor with three plane locking system

A combination carrier and precision stop assembly for use in a conveyor system, the combination comprising:

• a carrier;
• a stop assembly;
• the carrier including
• an upper surface for supporting a workpiece and an undersurface for frictionally engaging a moving conveyor,
• means for engaging one side of a stop assembly, means for engaging a second opposing side of the stop assembly, the carrier being vertically raised upon engagement of the two opposing sides of the stop assembly and allowing the conveyor to move forward underneath the carrier without frictionally engaging the undersurface of the carrier,
• means for receiving an initial braking mechanism to initially stop the carrier upon arrival at the stop assembly,
• the stop assembly including
• an initial braking mechanism and means for activating the initial braking system for initially stopping the carrier upon arrival at the stop assembly,
• means for engaging and lifting opposing sides of the carrier,
• a first sensor, the first sensor detecting the presence of the carrier after the carrier is initially stopped by the initial braking mechanism,
• means for communicating the presence of the carrier to a programmable controller upon the arrival of the carrier at the stop assembly.
