OPERATION

The operator loads screws into a vibratory feeder bowl. The screws orient automatically and feed into a decline track. At the base of the track one screw is escaped and is loaded into the chuck jaws by the inserting shuttle. The drive bit advances, contacts the screw, turns, and falls into the screw slot shutting off the drive motor. The driving unit and chuck descend toward the work piece. When the screw contacts the work piece, the resulting pressure of the screw against the bit starts the drive motor. As the screw is driven, the driving unit cams open the chuck jaws to clear the screw head. The drive motor automatically shuts off when the desired screw torque or depth is reached. The S-250 then resets to the start position and is ready for the next cycle.
