SYSTEM AND METHOD OF CLOSED CARTON INSPECTION
First Claim
Patent Images
1. A method of inspecting a closed carton, comprising:
- directing electromagnetic waves from an electromagnetic light source at a height of a fill-line of a reference carton containing required elements at the fill-line;
receiving electromagnetic waves penetrated through the reference carton by a receiving unit;
determining a reference intensity value by the receiving unit;
directing electromagnetic waves from the electromagnetic light source at a closed carton at the height of the fill-line of the reference carton;
receiving electromagnetic waves penetrated through the closed carton by the receiving unit;
determining a measured intensity by the receiving unit;
comparing the measured intensity value with the reference intensity value;
wherein if the intensity value is different from the reference intensity value, the closed carton does not contain the required element including missing leaflets at the fill-line; and
determining if the closed carton is correctly filled based on the comparison of the measured intensity value with the reference intensity value.

Abstract
An inspection of a closed carton for acceptable content fill may be provided by a transmitting unit and a receiving unit measuring intensity values of electromagnetic waves directed at the carton. A comparison of a reference intensity value to a measured intensity value may indicate whether the closed carton is filled correctly identifying missing contents such as the main product or a missing leaflet that may contain product instructions.
