Apparatus and method for applying and verifying marks on the periphery of generally cylindrically-shaped objects
摘要
An apparatus for applying and verifying a printed mark on the periphery of generally cylindrically-shaped objects as they travel on a path. The apparatus comprises at least a first conveyor mounted for movement on a first side of the path. The first conveyor is located to engage the objects to translate the objects at a known translational velocity along the path. A transport assembly is mounted for cyclic movement back and forth along a transport assembly path parallel to the path of the objects at least part of the cyclic movement being approximately at the known translational velocity of the objects. A mark applicator is mounted on the transport assembly and is located in a position to apply a mark on each object as the object is translated by the first conveyor. A sensor is mounted on the transport assembly. The sensor is located in a position to read the applied mark on each object as the object is translated by the belt. The sensor generates a signal representative of the mark.
