that the design and the construction of a shell making plant is a team job; many skills are necessary to make it work: electrical engineers, mechanical engineers, IT engineers, safety specialists, all of them well coordinated. At the same time in a shell making system, there are rotary tanks of different sizes, sanders, shell driers, automatic lifters to load and unload the finished shells, data acquisition system, and everything is orchestrated to serve the main robot standing in the middle.
Safety is our main concern in all plants, but this one require specific attention due to the robot presence. It will be our pleasure to show you each detail that make this plant safe for the operators and very easy to use and maintain.
One of the most important concept you have to care about when designing this kind of work cell is reliability. For whatever reason this plant stops due to power supply failure, the plant must restart as soon as energy recovery occurs without losing the partially finished shells. That’s why we have designed this plant to accept two different power supplies so that if first fails, the electric cabinet automatically switches to the one still available.
At each working step, all data are backed up on your database server, so that in the remote event that both power supplies fail, or in the unlikely event that the main PLC cpu fails, you can recover from backup without losing a single shell, or a single rotary cabinet slurry.
Our rotary cabinet are designed to recognize their position inside the cell or outside in the maintenance areas, so that every operation done with the tank is recorded and stored away for later analysis.
The tank itself is designed to be safe for the operator and safe for the process. Each tank has its own rotatory speed (inverter) and temperature regulation on board, so that it can work far from the cell in the slurry preparation area, but still networked with cell to keep track of the operations.
Simplicity first: each tank has only one connector with power, network, position identification signals and compressed air, so that with just one plug, you will have the tank up and running.
As a plus, our rain cabinet are equipped with sand sievers to remove the sand that does not respond to grain size requirements.
