For applications requiring gravimetric filling accuracy at a medium speed, a programme forward system provides an excellent solution. Line speeds between 20 - 40 containers per minute can be achieved, depending upon the volume & type of product to be discharged and the container to be filled.

These systems can be fitted with two or three filling heads. The first filler (first two fillers in the case of a three head system) discharge on a volumetric basis to form approximately 70 - 80% of the overall fill, the container is then transferred into an integral weigh station that constantly monitors the product bulk density and adjusts the bulk fillers accordingly, as well as calculating the required discharge for the top-up fill on an individual basis. The container then transfers beneath the top-up filler and receives the calculated discharge. Finally the container is transferred to the integral check-weigh station that monitors & dynamically corrects any density variations from the top-up filler, and verifies that the total fill is within the pre-set tolerances. Should any out of tolerance fills be detected, these can be rejected at the next index station or tracked to a pre-determined reject station.


An optional container tare weigh station can be fitted at conveyor in-feed for tracking actual container weight, should varying container weight be a problem. This would usually be the case of containers such as glass jars for example. Optional vibration stations can be included at fill points & if necessary at subsequent stations to aid product settling within containers. Statistical reports on filling performance can be generated by connecting optional printer to the data connector included as a standard feature on all lines. In common with other in-line systems, a touch screen operator panel provides line control & parameter settings.
