Weigh Hopper Automation Systems

Accurately fills large containers, gaylords etc. to within 0.5 grams
Unlike cycle count systems that can come up short due to bad shots or machine interruptions, the Weigh Scale Hopper accurately fills even very large containers with the same levels of accuracy as small containers.

Exceptional Versatility:
Weigh Scale Hoppers can be conveyor mounted or portable and both are used with almost any type of container filling system – including, In Line, Automated Turntables, bag filling, box filling, multi level storage systems, etc.

The Weigh Scale Hopper can be specifically engineered to suit individual application needs. Options include double load cells, extra large hoppers, etc.

Weigh Hopper

  • Accurate – Because the Hopper weighs in small batches, it can achieve a much greater level of accuracy than traditional platform style weigh systems that must weigh the container, scale platform, and total number of parts.
  • Fast – Does not need to stop filling while a new box is moved to the fill position.
  • Flexible – Can be used with almost any box or bag filling system.
  • Space Saving – Does not require a separate fill station.
  • Economical – Costs less than traditional weigh scale systems.

Protect Workers & Equipment:

EMI’s batch mode, Weigh Scale Hopper was specifically developed to provide maximum, part counting accuracy. Depending upon the size of the load cell selected, Weigh Scale Hoppers are capable of detecting part weight as small as 0.5 grams. The final accuracy of a system is dependent on the specific application—the size of the parts, the number of parts on the final cleat, etc.

How does it work?

  • By sampling a given number of parts in the hopper, a part weight and batch weight is determined.
  • The number of parts required for a full container is entered into the control system.
  • The feeding conveyor fills the Weigh Hopper until the batch weight is reached.
  • The feeding conveyor stops momentarily while the Weigh Hopper dumps the batch into the container.
  • Batches are filled into the container until the final batch is being filled. The controller then determines how many more parts have to be filled to meet the final weight. As the final parts are being filled, the controller slows the feeding conveyor to allow the parts to slowly dribble in.
  • The hopper dumps the last batch, zeros itself out and immediately begins filling again.
  • The container indexes and a new container takes its place.
