EBI Classification

What 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. …

One of the greatest and most expensive linear Empty Bottle Inspectors today existing in the World: GROLSCH® at Hengelo, The Netherlands (CARLSBERG® Group). An image shot by our staff when installing and powering it. It is used at a speed of only 40 000 bottles per hour and equipped with a wealth of 18 inspections. Its binary classification task is accomplished by mean of 4 rejectors: 3 in its outfeed (lower side in the image) and 1 in its infeed (upper side in the image). The total length of conveyors controlled by this Empty Bottle Inspector is ~14 meters. Its total price ~2 000 000 $

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 (image credit C. López-Mariscal, US Naval Research Labs., 2014) Semitransparent and transparent foreign bodies are much more difficult to detect than opaque. Plastic foils like those folding packs of cigarettes, are often encountered in the base of RGBs (Returnable Glass Bottles). Plastic foils rotate in a fixed direction the spin angle of the polarized light. Then, to detect plastic foils, light is forced to pass thru an additional delay filter, whose delay is related to the angle with whom all plastics rotate the plane of polarization. Finally, a separate base camera detects these images. To detect the truly difficult completely transparent cigarette plastic foils, it is not as efficient as the Inner Sidewall inspection.

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. …

Finish inspection, broken Thread

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;…

Scuffing inspection

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. …

EBIs Infeed checks

Infeed ChecksEmpty Bottle Inspectors always need to be protected by prior controls and rejector, to prevent damages implicit in their operation. Damages 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”. …
