2. Conveyor and Sensors Figure 1 depicts a part of a factory that makes bubble gumballs. The gumballs travel on a conveyor that has three associated sensors S1, S2, and $3. The sensor s, is connected to a scale that weighs each gumball, and if a gumball is not heavy enough to be acceptable then the sensor sets sy = 1. Sensors s2 and s3 examine the diameter of each gumball. If a gumball is too small to be acceptable, then s2 = 1, and if it is too large, then s3 = 1. If a gumball is of an acceptable weight and size, then the sensors give S1 S2 S3 = 0. The conveyor pushes the gumballs over a "trap door" that it used to reject the ones that are not properly formed. A gumball should be rejected if it PLC Lab Fourth Year Page 2 جامعة البصرة كلية المندسة COLLEGE OF Whinin ENGINEERING VERSITY OF BASRA Department of Electrical Engineering College of Engineering University of Basrah -gumball is too large, or both too small and too light.
