In the networked filling system of Haver & Boecker, weighing and weight checking systems communicate with other machine components and control the filling process of chemical products. The machine control system regulates the filling operation of the bulk goods at the packer where the filled product is weighed continuously. The weight checking scale continuously transmits the actual bag weight and precise-to-the-gramme suggestions for achieving a precise correction of the filling amount. The bag’s actual final weight is recorded by the discharge conveyor’s weight checking scale only after the filled bag is discharged from the bag chair. A possible minimal product loss arising from the bag’s discharge cannot influence the measured actual value. At the same time the transfer of determining the actual filling weight over to the discharge line leads to an increase in filling performance because the process ends more quickly without weight checks. Incorrect weight bags are detected and diverted. Here the check-weigher communicates with the diverting unit. The entire system interacts with other company hierarchal levels and thus can be influenced from outside the production. Collected data may be transmitted to the Haver DPS data processing system, saved, and statistically evaluated.
