Progressive Logic
Progressive Logic functions such that no zones are set to accumulate unless all downstream zones hold
accumulated product and the photoelectric sensors are blocked. In the above example, the discharge
zone, Zone 1, is shown stopped which is a result of the release from the zone being inhibited and the
Zone 1 sensor being blocked. Zone 2 sensor not being blocked results in all upstream zones, Zone 2
through Zone 6, running.
Note that with Progressive Logic products being transported on the conveyor can remain tightly packed,
without any gaps being created.
Discharge from Progressive Logic
A Singulation Release signal given to the Zone 1 Logic Assembly releases product from that zone. Each
successive upstream zone will also begin releasing product, but with a two tenths of a second release
delay from each zone to the next upstream zone. This will create a small gap between released products,
depending on product sizes, the number of products occupying each accumulation zone, and the
conveyor speed.
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 Progressive Logic function. The two tenths of a
second release delay between zones does not occur with Slug Release.
