Zero Pressure Accumulation Conveyor prevents products from touching in-transit
In order to ensure that products do not touch each other while they accumulate, zero pressure accumulation conveyor is used. Zero pressure accumulation conveyor features a photo-eye sensor in each zone which sends a product presence signal to a zone controller. If there is a product present in the immediate downstream zone, then the zone controller prevents the drive rollers from activating. Once the zone controller receives a signal indicating that the next zone is clear of product, the drive rollers are activated thereby conveying the product to the next zone. There are multiple methods of releasing product downstream with Zero Pressure Accumulation Conveyor. The standard method will have an empty zone between each product. For quicker throughput all of the product can be released together in a “slug” mode. There are methods in between these two techniques called “cascade” release that have programmable timed releases between products. Each of these release methods provide specific throughput characteristics.
