It permits to pallet the fertilizer bag according to two types of configurations:

Chimney Configuration Epi Configuration :

The industrial PLC wich manages the process must take in account different informations relative to physical states as:

The presence of a bag to the input of the system.
The switch position.
The presence of bags at the exit.
The rank of the bag during the palleting process.

Composition of the equipment:

The system includes a switching functional chain of the bags ref a configuration and orientation functional subset of the bags ref and a module.

These three elements permit a progressive approach of the palleting process technology, and practical works oriented toward the knowledge of the sensors, pre actuators, actuators, effectors, the mechanical links and the initiation to automatics.
