The aluminum frame is guarded by panels over motorized and belt transmission areas to prevent personnel injury. An overhead structure supports and houses photosensors used to detect pouches, one per stage.
The Staging module utilizes regularly-spaced o-rings in grooved shafts to act as the main transport surface for pouched product.
Each of staging modules allows product to pass from the upstream to the downstream modules only when a photoeye, in conjunction with a pre-programmed algorithm, indicates that the module immediately downstream is empty. If not, product is slowed or stopped until all of the necessary conditions have been met. In this way, the system ensures error-free packaging by eliminating empty or over-stuffed cartons.
Three of the discharge modules are activated based on a first come, first serve basis, and remain activated for a short time period to allow proper transfer of the products onto the merge discharge conveyor.
