METHOD AND APPARATUS FOR INSPECTING AND CUTTING ELONGATED ARTICLES

摘要

A cutting wheel assembly (100) for cutting elongated articles having a cylindrical housing (101) which defines a longitudinal cavity (102) and a circular outer periphery (103). A plurality of cutting blade support rings (180) are rotatably mounted about the outer periphery of the housing (101). A plurality of cutting blades (170) are mounted for radial mouvement on each ring and and disposed at angularly spaced increments about the housing, wherein each blade is moveable between a first, non-cutting position and a second, cutting positon. A manifold and valve assembly (130) is mounted in t he cavity and proximate the cutting blades for selectively directing a pulse of fluid against individual blades at preselected angular positions to urge the blades outwardly from the non-cutting position to the cutting position. A plurality of camming components (183) are positioned about the periphery of the housing and secured against rotation adjacent the rings. The camming components include tracking grooves (184) for receiving portions of the blad es which guide the blades along the cutting and non-cutting positions, and whic h maintain the blades in the cutting position without continued presence of th e fluid.
