Missing this is as easy as not playing the game! 
The conveyor belt levels are levels 51-60. These levels are often times an exercise in your timing abilities. Take a minute to observe the level before making movements if you can. Once Robby hits those conveyor belts, he'll go flying! So watch out.
The developer has a walkthrough video posted. Its for the phone version but works with the PC version.
