Conveyor Scales

Accuracy + Repeatability = Piece of Mind

Applications

  • Direct Food Contact
  • Verifying box or bag weights
  • Dry foods/goods
  • NTEP weight verification
  • Variable weight labeling
  • Shipping

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.

Our NTEP Certified Inline Conveyor Scales offer incredible in-motion weighing accuracy with high speed capabilities. We offer complete customization to ensure the scale fits within your existing processes and meets your exact needs.

Features & Benefits:

  • Industrial controller samples weight at 60-80 samples/second for efficient weighing
  • Easy interfacing with other systems such as sorters, classifiers, automatic box weigh labeling, manual box labeling and more
  • Single load cell design simplifies calibration maintenance and operation
  • Smooth belt driven design ensures minimal vibration during weighments
  • Safety stops help protect load cells from abusive treatment

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.

NTEP is required when you are selling your product based on its weight.  Therefore all food processing facilities require an NTEP inline conveyor scale in their facility when capturing product weight.  NTEP is also required when transmitting a weight for creating a shipping label.

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 Scale 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 reduce 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.
