Abstract (en)
An improved mechanism for coordinating the transport of a glass container through an inspection zone with the movement of an inspection head relative to the container. In a plug gager, a carriage (16) which holds the plug gage (13) is moved in the direction of container travel by a cam (90), while an eccentrically-mounted bearing moves the plug gage vertically to penetrate the container finish. The invention provides an improved cam profile (95) to provide an increased maximum stroke (amount of gage penetration) making the apparatus adaptable to a wider range of container sizes. Relative to prior art cams for apparatus of this type, the constant velocity segment of the cam motion is extended. A similar adaptation to a leak detector utilizing this cam-driven carriage and inspection head arrangement lengthens the segment of each cycle during which inspection occurs, increasing the sensitivity of the system. In a check detector utilizing this arrangement, this improved cam-driven mechanism provides increased inspection speed and accuracy, and allows better stopping of containers at high speeds.
