Dear All,
Basically there are 8 conveyors as shown. Each conveyor will be controlled by a Siemens Micromaster 420 Drive. And each conveyors has a proximity switch/sensor to sense the container.
The objective is to move the container from one area to another.
The PLC used is the S7-300, 315-2 DP.
Anybody can guide me on how to do the above? Basically i am from the process control background and this is the 1st project involving a conveying system which is more to factory automation/motion control. I am unsure on how to move the container i.e. how to start/stop the conveyors.
The system looks simple but i think it is more complicated than that, as i have to address the following issue :
1) The conveyor must only move/activate when there is a container on top and the conveyor in front is empty.
2) Need to track the location of the container on the conveyor belt.
3) There may be containers queuing or stopping in front i.e. maybe on conveyors 4 and 5. Therefore the system must be intelligent to move and stop the incoming containers on conveyor 3; and to move only when conveyors in front are empty.
I would appreciate if anybody out there can just guide me on the correct path to implement this project.
Thanks.
