In-Motion Checkweigher

Reduce Your Product Give-Away

Need Customization?

We can customize a checkweigher to your exact specifications. This results in optimized speed and accuracy for maximum throughput.

Tired of Small Displays?

VBS integrates an impressive standard 17″ Human Machine Interface display for almost unlimited reporting and display options. You want larger? We can do it!

No parts pricing sucker punches!

VBS uses standard, industry-available components that are easily attainable from multiple vendors, in the design and construction of our equipment assuring our customer economical, simplified, fast and efficient maintainability.
Vande Berg Scales In-Motion (Dynamic/In-line) Checkweighers employ state-of-the-art features which make them the best value in the industry. Our checkweighers give you an accurately weighed product that you and your customers can trust.

Features & Benefits:

  • Reduces product “giveaway” which saves you money
  • Reduces false rejects and rework thereby saving time and money
  • Incorporates an extremely durable and cost effective load cell vs. magnetic force restoration technology that can be costly, delicate and complicated.
  • Most units are backwards compatible ensuring replacement parts will be available for years vs. having to replace the entire unit due to discontinued product line excuses.
  • Off-the-shelf parts ensure you can easily source replacement components so you are back in operation.

  • Draft shield protects scale from environment triggered weighing errors

FAQ

A conveyor scale simply acquires the weight.  This weight can then be stored on the scale or sent to another device.

A checkweigher will acquire the weight, compare the weight against an upper and lower limit, and then take an action.  Just a few examples of actions are illuminate a light, stop a conveyor or divert the product off the line for rework (most popular).

No.  Stopping the conveyor for each product would significantly increase component wear & tear, and reduce the throughput.

Even while in motion our NTEP certified scale and algorithm will accurately determine the weight of the weight of the product.

Most of the time, No.  A checkweigher is primarily used to validate how well a package, or container, was filled upstream.  The upstream scale, or filling machine, needs to be NTEP.

Yes to both.  We offer RS-232 (serial) and Ethernet communication as standard.  You can see the database being populated or export the data after a finished run. (Ethernet IP option is also available.)

Innovative Checkweigher Design Elements

Single drive design virtually eliminates the harmonics that can result when you have dual drives (one on each conveyor end). Harmonics often develop when motor speeds are not precisely matched. The result is internal scale movements that can significantly affect weighing accuracy.

It took years to figure out, but we finally came up with a single load cell design. The result is a scale that is more reliable and less cost. The reduced cost part is obvious, but what about the reliability? Most scales have 4 load cells (one of each corner), so when one load cell fails, the entire scale is out of commission. Having a single load cell design significantly reduces the chances of overall load cell failure.

Since we only have one load cell, we can reduce cost by eliminating the junction box.

Moment forces need to be considered with a single load cell design. VBS has engineered a unique multi-angled bracing that consistently transfers weight to the middle, where the load cell is located.
