A conveyor system for delivering work pieces to a predetermined area comprising a first conveyor, a second conveyor disposed at an angle to the first conveyor, a mechanical brain, and a transfer apparatus (arm) at the juncture of the first and second conveyors. The mechanical brain has a shim, a rotating disk and sliding plates on the disc that are temporarily moveable to form a protrusion that rotates with the disc. The disc rotates at a speed that is a function of the speed of the first conveyor and the protrusion activates a device to create a light path transverse to the first conveyor near the first and second conveyor juncture just prior to a workpiece entering such juncture. The protrusion is returned to its normal state, subsequent to the creation of the light path, by the coaction of the rotating disk and the shim. The workpiece interrupts the light path causing the transfer apparatus (an arm) to divert the workpiece to the second conveyor and upon the reestablishment of the light path, the arm is caused to retract.
