Abstract
An inspection apparatus for inspecting and detecting flaws in serially fed substantially cylindrical objects. The inspection apparatus includes a notch-shaped inspection station formed by a pair of drive wheels mounted on a first shaft and a pair of discharge wheels fixedly mounted on a second shaft, parallel to the first shaft. A hook having a convex back surface is connected to and protrudes beyond the circumference of each discharge wheel. An L-shaped bracket whose body includes a sending surface and whose leg includes an infeed cradle, is mounted above the drive wheels and pivots in synchronism with the rotation of the discharge wheels. A first object in the infeed cradle is positively sent by the bracket sending surface toward the inspection station as the hook convex back surfaces are rotating up through the inspection station. The sent first object contacts the hook back surface which by its clockwise rotational motion imparts a counterclockwise rotational motion to the object while easing it into the inspection station where it is rotated and inspected for flaws by sensors mounted axially on an imaginary straight line drawn from the axial center line of the inspection station to the axial center of the first or second shaft.
