Process Description

The FIBC gross weigher cycle starts with manual bag placing onto the bag hook which is suspended from the weighing platform structure. By starting the feed, normal weighing cycle commences from zeroing the empty FIBC continued by the product feed cycle with main and fine feed. The weighing controller calculates the two cut-off weights required for the target weight. This is achieved by calculating the target weight and then adding a fine compensation value to determine the fine feed cut-off set point.

Product feed begins by opening the feed gate to the main feed position.

The weight in the bag is monitored and when the main feed cut-off weight is reached, the scale feed is switched to fine feed.

The weighing continues at the lower feed rate, until the fine feed cut-off set point is reached. The feed is then stopped, and a check weigh steady timer starts. This timer allows the entire in-flight product to settle in the bag. The achieved weight is then stored, and the bag is ready to discharge.

The FIBC mouth clamp will be released and the bag will be lowered down to the bag conveyor or empty pallet for discharge.

The controller records the last weighing and compares the fine feed time against the current set point, and an adjustment is made to the fine feed compensation value when required. The final weight is checked, and averaged to determine whether the weight compensation value requires adjustment. Calculations are concluded, with any adjustments made if required. The next weighing cycle is ready to start.
