Solution for snack foods manufacturer increases operational efficiency

THE BUSINESS NEED: 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 THE OPPORTUNITY: “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 THE SOLUTION: 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.
