avancon ZPC powers each zone separately in the moment when something has to be transported on this zone. If the zone in front is occupied, it stops and consumes no energy; if the zone in front is empty, it transports with 0.3 m/sec. to the zone in front;
if 5 zones in front are empty, it transports continuously with 5 times the speed (1.5 ms) to and over the zones in front... and so on.
In addition, the avancon ZPC concept always starts and stops smoothly. During operation, there is of course a gap of one zone length between the goods to be transported. It's similar to driving on the highway. Even if you are driving fast - if everything stops in front of you, you have to hit the brakes soon enough.
This means: If in front there is already a good standing, it will accumulate with zero pressure and will not touch the goods in front.
Whereas zero-pressure accumulation systems are used mostly before a working station, a crossing or at the end, because these systems are more expensive than just powered system, avancon uses this principle always and for all conveyors.
This modern avancon conveyor concept has six patents in most industrialised countries.
