18 Position-based Output Control with the MAOC Instruction
Product Diverting Example
In this product diverting example, jugs of orange juice pass along the conveyor
belt while sensors determine the fullness of each jug. If a jug is not full, it is
deflected off of the conveyor belt, as shown below.
Figure 18 - Product Diverting Example
The programming logic for this example must take into account the following:
• The sensor and the center of the actuator are 9 in. apart.
• Each bottle is nominally 12 in. apart.
• The conveyor measures the position of the bottles in inches.
Typically, you can use timers to measure position with constant speed
conveyors, but if the conveyors are starting and stopping regularly, use the
position of the belt instead of timers.
