Classification on base of the kind of container 

Empty Bottle Inspectors (EBIs) and the related measurements whose goal is a binary classification (collectively named inspections), are a category making a particularly sensitive activity: to protect final consumers' health, assuring beverages' safety in the Food and Beverage Packaging Lines.   EBIs are differentiated as visible below for the kind of application in the Bottling Line layout, as:

Classification on base of the Measurement’s Principle

The classification of the EBIs can be fully accomplished including the physical principle used to measure the property.    With reference to commonly applied inspection, corresponding to the countermeasures to common eventualities (“risks” for the Food and Beverage Safety), we have the following scenario:

Example

An Electronic Block variant

In the figure below, an example of EBI whose mode of operation could be considered a variant of a standard electronic block.  This EBI operates with an inner starwheel with suction cups adhering to bottles’ sidewalls, to allow the base and IR residual liquid controls necessarily needing a longitudinal view of the bottle, as seen by its neck.  This starwheel operates with the bottles being pushed-in, say with pressure of bottles kept sliding on the in feeding conveyor.

For the external sidewall inspection it is equipped with a bottle auto-rotator system, providing a full 360º rotation. Bottles are rotated while passing a high-speed camera where up to 12 images of the entire outside surface of every bottle are captured for complete coverage.  After the EBI the bottles lie in a true and standard electronic block, recovering the holes in the bottles’ flow, due to the EBI rejection.

Classification on base of the kind of container Empty Bottle Inspectors (EBIs) and the related measurements whose goal is a binary classification (collectively named inspections), are a category making a particularly sensitive activity: to protect final consumers' health, assuring beverages' safety in the Food and Beverage Packaging Lines. …

Rotary-Linear EBI ComparisonRotary EBIThe Empty Bottle Inspectors of the past were always and only Rotary Machines. The industries which first started to design and produce them and those which adopted them, were all US-based and specialized in the production of glass bottles. …

Introduction When discussing elsewhere the High Frequency fill level inspection, we also examined the complex mechanism of interaction between the High Frequency (HF) electromagnetic waves (3 - 30 MHz) and polar liquids like water. …

Introduction It is a fact: when bottles are urgently needed, also glass returnable bottles born to host beer or mineral water, can fulfill their basic purpose of container for liquids of completely different nature. …

Introduction Base inspection is the most important at all and also the first historically created for EBIs. In the start, it was applied to small inspectors used by glass bottles Producers. It is always present in the Empty Bottle Inspectors, as a minimum standard, jointly with a few others like the High Frequency Residual Liquid control and the Finish inspection.

A common PET bottle as visible with (right side) and without (left side) polarising filtering. At right side, cellophane in the stripes around the bottle rotates the light polarization vector (  …

Introduction The term “finish” originates with the mouth-blown bottle production process where the last step in completing a finished bottle was to finish its lip. Today, the lip or finish is the first forming step in the bottle making process. …

Operative principleThe operative principle of the Finish inspection is applied, in a similar way, to the more complex case of check of the status of the glass threads. In this case, light is generated by an illuminator on top of the finish. …

In the Linear Glass Returnable Empty Bottle Inspectors, External Sidewall Inspection may be performed adopting one or two CCD-cameras. We’ll treat in the following the application with two CCD-cameras: single-camera applications are not satisfactory, covering only < 80 % of the external surface of the bottles.

Why Inner Sidewall InspectionThe inner surface of the bottle may host larvae, insects and other low-contrast foreign objects whose detection, as seen by the External Sidewall is nearly impossible. …

IntroductionThey exist defects no Bottle Washer shall never remove, whatever the duration of its cycles, the amount of caustic soda or temperature of the water. Between these:Paint, internal or external;…

IntroductionScuffing is a memory of the many passages of the returnable bottle thru the Bottling Line, mainly of the wearing of its external sidewalls after friction with other adiacent bottles. …

Infeed ChecksEmpty Bottle Inspectors always need to be protected by prior controls and rejector, to prevent damages implicit in their operation. Dammages originated by: fallen bottles, inclined bottles, …

IntroductionTo perceive the rationale for the inspection of the bottles’ colour, we recommended to take a look at the figure on right side. That is what a Customer considered “a bottle format”. …
