Welcome to Page 2...
That part 'should' be fairly easy. Whatever device you use to 'track' the bottles can just be filled with 'failed' bits/words at powerup. For instance, if you're using a shift register, with a value of 1 representing 'passed' inspection, and 0 (zero) representing 'failed' inspection, just fill up the shift register with zeros at powerup. You could just make the bits (or words) non-retentive and they'll automatically go to zero with no power.
Too bad you can't do the inspection and reject while the bottle are still in the labeler's timing screw. Once they leave the screw, you lose that control. The phrase "You're screwed" comes to mind (actually, that fact that you're NOT screwed is the problem)...
This project may be slightly advanced for a beginner, but it's definately a worthwhile learning experience!...
