Abstract: Apparatus is provided to conduct an automated foam pick operation on a production bottling line, to withdraw a biased sample of suspect bottles based on abnormal foam characteristics, which sample is then directed to an automated full bottle inspection operation that is set to monitor bottles at a statistically validated sampling rate. A method for conducting automated foam picking and candling in tandem operations is also provided.

Abstract: The present invention provides a very simple and inexpensive device and system for mechanically detecting and, optionally ejecting non-standard bottles and other articles from a line composed of standard and non-standard bottles traveling on a conveyor. The device can be quickly adjusted as required to detect bottles based on various physical differences between the types of bottles such as diameter, buffer zones, neck diameters, shoulder heights, etc. The device is inexpensive, requires little space or maintenance and can be adapted to handle many types of non-standard bottles. It can also be used to sort articles based on those physical differences.
