Basic Logic
Basic Logic functions such that when any two successive photoelectric sensors are blocked, the second
zone upstream is set to accumulate. In the above example, the discharge zone, Zone 1, is shown
stopped, signifying that release from the zone is being inhibited and the Zone 1 sensor is blocked. Zone
1 sensor blocked and Zone 2 sensor blocked results in Zone 2 being stopped. Zone 3 and Zone 4
sensors are not blocked, and the zones are running. Zone 5 sensor is blocked, but the zone is running
because the Zone 4 sensor is not blocked. Zone 6 is stopped because both Zone 5 and Zone 6 sensors
are blocked.
Note that with Basic Logic products being transported on the conveyor are separated by a gap of at least
one zone length. This will reduce the transportation throughput capacity of the conveyor. The rate at
which product is introduced onto an accumulation conveyor of this type must not exceed the
transportation capacity of the conveyor.
Discharge from Basic Logic
A Singulation Release signal given to the Zone 1 Logic Assembly releases product from that zone. As
released product clears a photoelectric sensor, the product stopped at the next upstream zone is
released. This will create a one-zone length gap between all released products, assuming conveyor
speeds (accumulation conveyor and downstream conveyor) are identical.
If the line is set to Slug Release (Train Release), all affected zones will run, resulting in the release of
product with little or no gaps. This overrides the normal Basic Logic function.
All product movement as described for transportation, accumulation, and discharge is based on zone
lengths, meaning only one product is in each zone. If more than one product should occupy a single
zone, which could occur with small products, they will usually move together or stop together, or they
could eventually become separated into different zones. This is true for both Basic Logic and Progressive
Logic.
