Net Weighers

Active Weighing Solutions Net Weigher is a fast, accurate and reliable filling machine delivering preset product weighments into bags at rates up to 20 bags per minute.

An Active Weighing Solutions Net Weigher will fill a variety of open mouth bags to a pre-determined weight with greater speed and accuracy than a Gross Weigher.

Operation

When the operator turns on the Net Weigher; the feed device automatically begins the filling process. When the preset weight is reached, the controller captures the bag weight and, if a bag is in position, it then discharges the weighed bulk product into the bag. The weigher immediately starts refilling while the bag is being discharged from the bag clamp and a new bag positioned.

The Net Weigher is designed to ensure the operators hands are clear of the Bag Clamp, using “whiskers” which must both be energized to activate the Bag Clamp and allow the discharge doors to open. This design also prevents material spillage in the case of a misplaced bag.

Flow Rate

While the bagging rate depends greatly on the material properties of the product being handled and the proficiency of the operator, an Active Weighing Solutions Net Weigher can achieve up to 20 bags per minute.

Accuracy

For free flowing products, an Active Weighing Solutions Net Weigher will typically achieve:

  • 25kg bags at up to 10 bags/min at ±20 grams (at 2δ)
  • 50kg bags at up to 10-20 bags/min at ± 50 grams (at 2δ)

Non free flowing products may require the bagging rate to be reduced to maintain the required accuracy.
