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.

Claims

1. An automated bottle inspection and handling system for discriminating and sorting on a statistically predetermined basis between bottles whose contents include foreign inclusion bodies and those which do not, said system comprising automated, high speed, foam picking means operable to inspect and foam pick bottles from all bottles being conveyed on said high speed bottling line and divert foam picked bottles therefrom to a lower speed automated candling means for candling thereof and sorting candled, foam picked bottles on the basis of said candling into two streams, a first comprising a greater proportion of those having a foreign inclusion body contents and a second comprising a greater proportion of those whose contents do not contain foreign inclusion bodies.

2. The system according to claim 1, wherein said first stream contains a preponderance of said candled, foam picked bottles having foreign inclusion body contents.

3. The system according to claim 1, wherein said automated high speed foam picking means and said lower speed automated candling means are rate compatible.

4. The system according to claim 4, further including rate moderating means intermediate between said automated high speed foam picking means and said lower speed automated candling means, said rate moderating means being operable to reduce that rate at which foam picked bottles are delivered to said lower speed automated candling means from said automated high speed foam picking means.

5. The system according to claim 5, wherein said moderating means comprises staging means operable to temporarily hold back foam picked bottles delivered at a transient delivery rate exceeding a rate compatibility specified delivery rate, from said automated high speed foam picking means to said lower speed automated candling means, and to release held back bottles from said staging means when said delivery rate falls below said rate compatibility specified delivery rate.

6. A method for discriminating and sorting on a statistically predetermined basis between bottles whose contents include foreign inclusion bodies and those which do not, comprising:

introducing bottles from a high speed bottling line into an automated, high speed, foam picking means operable to inspect and foam pick bottles from all bottles being conveyed on said high speed bottling line and divert foam picked bottles there from, and then,

passing said diverted foam picked bottles to a lower speed automated candling means for candling thereof and sorting candled, foam picked bottles on the basis of said candling into two streams, a first comprising a greater proportion of those having a foreign inclusion body contents and a second comprising a greater proportion of those whose contents do not contain foreign inclusion bodies.
