Cracker Package
Contents Confirmation

Challenge
 Customer needs to confirm that each of four foil cracker packets is present in a standard carton of saltine crackers. This inspection also helped to guaranty that none of the cracker packets fell or became tangled in the carton-filling machine. Each failed carton can be removed before carton sealing to prevent recall or customer dissatisfaction.

Solution
Using Omron's F150 or F160 vision sensors to perform a single binary area inspection across the entire packet contents area to make a presence determination based on the total area count to provide the solution

How it Works
A single area inspection region is created around the internal contents cavity of the cracker carton and the binary area count with all the packets present are set as the base line for presents.

By using the binary area and gravity tool in both the F150 and F160 products, the total area count can be identified and monitored easily.  With the use of a diffused LED based ring light mounted directly in front of the lens, there is adequate front light to highlight each packet area location in the cavity with ease.  By using the F150 or F160's Area and Gravity tool, a single minimum and maximum tolerance can be set as a judgement to determine a missing packet.  Using the standard OR output of the controller as the pass/fail output, no other outputs are required to determine presents or absents.
