This system can be purchased as an extension to the single conveyor system (34-001 or 34-002) or as dual conveyor system. It extends the parts selection task into a simple assembly
process.
Plastic and Metal components are selected by size and the material fed onto chutes for
dispensing into a final assembly task where they are combined with the second
component.
The finished product is then stored by material type or type of assembly.
The added complexity of this system allows further study of PLCs in process control
systems. Students are required to consider in more detail the structure of control
systems.
More complex control scenarios can be developed using combinations of timers and
counters with master and zone control functions.
The system requires a PLC capable of driving the following inputs and outputs:
