Solution for snack foods manufacturer increases operational efficiency


A leading snack foods manufacturer, belonging to a division of a large global consumer packaged
goods (CPG) company, recently approached Hardy regarding their checkweighing needs. Existing
product inspection systems were not meeting their operational expectations. The Customer’s Project
Engineer told Hardy that they were “challenged by not being able to repeatedly meet their speed/accuracy
checkweighing specifications of better than 250 milligrams resolution, at 400 milliseconds per pack”.
In addition, their existing systems:
• required expensive “green board” custom hardware
• had proprietary software
• and maintenance was expensive and unreliable
“They wanted to find and implement an alternative solution. They felt they had an opportunity to reduce
manufacturing costs by minimizing product giveaway, if they could just meet their check weighing
specifications consistently, “ explains Area Business Manager, Stan Modzel. At the same time they
wanted to install checkweighers that would:
• use off-the-shelf, open source, non-proprietary technology
• be easy for the operators and maintenance folks to use, modify & maintain
• retrofit into existing system
Hardy’s Engineering Manager, Dean Raby presented the Customer with the solution: “We offered them
multiple HI4050CW check weighing bundles. This solution met all their needs.” The check weighing bundle
consists of a digital, ceramic load cell and check weighing controller:
• It was easy to install, use, maintain & modify.
It is cost effective. It’s not a black box, it is an
off-the-shelf solution. It easily integrates to
Rockwell and other PLC’s.
• It was able to manage up to 250 packs per
minute. It breaks the traditional analog strain
gauge “speed barrier”, without the cost of MFR
(Magnetic Force Restoration or Other similar
high speed / resolution technologies)
• It delivered many smart check weighing
features. It offers advanced EDGE DETECTION
(weight on & weight off) eliminating the need
for photo eyes. It provides the operator with
real time indication of DATA QUALITY.
Plus it has an embedded DATA LOGGER, which
can be used during startup or trouble shooting.
