What Container 




Full Container Inspectors and the related measurements whose goal is a binary classification (collectively name inspections), are the widest existing family between the Electronic Inspectors in the Food and Beverage Packaging Lines.   Full container inspectors are differentiated as below for the kind of container inspected, can, keg or bottle (glass bottle, PET bottle, PRB bottle, aluminium bottle):

   Full container inspectors’ classification based on the kind of containers


What Tracking




Another fundamental design-dependant, inital parameter is the way the filled containers shall be tracked.  "To track" is possible in presence of “synchronisation”.  It implies the persistence of the information regarding the identity of the container, along its entire displacement thru one or more consecutive Shifting-Registers, where identity is attributed before, a measurement made later, and a classification (eventual rejection) in the end.

  Full container inspectors’ classification based on the kind of containers’ tracking (synchronisation): based over contanst speed or encoder.  The Encoder-based themselves divided in two main categories: standalone and in-the-Filler, Closer or Labeller Machines









A complex example of synchronisation referred to a chain cycle (Shifting-Register) is visible in the video below referred to the Brewery Carlsberg™ UK at Northampton, United Kingdom.  Here the Conveyor outfeeding a Glass Empty Bottle Inspector, and those joining a 60000 bph Filler Machine to the Rejects and Sampling Accumulation Table of a Full Bottle Inspector (FBI).   Visible 6 Tracking Triggers assuring the inspection of containers' “most valuable information”, their Identity, along 3 consecutive Shifting-Registers.  Each of them mapped in the Electronic Inspection equipment memory.  In 2005 our Staff spent over 1 day calibrating the tracking system to assure the FBI’s sharp, unique attribution of the actual couple (Filler Valve, Closer Head) which filled and closed the bottle. Calibration resulted in < 0.5 % of the couples  (Filler Valve, Closer Head) false attribution.  In the case of an Label Presence Inspection in-the-Labeller Machine, also basic precondition for any meaningful Localization to the correct Labeller Station.

Measurement Principle



With respect to the figure below, reducing the field to the bottles, whatever the material they are made of (glass, PET, PRB, aluminium) the classification can finally be accomplished including the physical principle used to measure the property. 

  Full bottle inspectors’ (FBIs) classification, referred to the most commonly applied shifting-register synchronisation.  In evidence the differentiation of the inspection solutions due to past decades of development. Today, following the kind of application, container and Line layout, they can be conceived over 16 different kinds of fill level inspection
