The Hardy Dynamic Checkweigher is a fully automated system designed to weigh items automatically in-motion. The Checkweigher controller can communicate both upstream and downstream across the connected enterprise network. Automated control is done with an embedded Rockwell Automation CompactLogix™ PLC while communicating with the high performance Hardy HI 4050CW check weighing controller. The resulting high speed check weighing system can process between 20 to 350 pieces per minute.
“Hardy’s new checkweigher family delivers the benefits of open source, off-the-shelf and seamless integration, enabling customers to maintain and enhance their checkweighers to meet future needs,” says Tim Norman, Hardy’s senior product manager. “We leveraged Rockwell Automation’s Premier Integration model using Studio 5000 software and Allen-Bradley components. This novel approach seamlessly integrates equipment data, control, and analytics into plant-level and enterprise networks and all data tags are visible and available on the connected enterprise.”
Each Dynamic Checkweigher has a stainless steel base and cabinet, for maximum durability and easy washdown. It weighs products of virtually any shape or size in containers such as boxes, cans, bottles, rigid shrink-wrapped packages, or flexible packages. Items compatible with the system include bagged and boxed sugars, raw meats, fruits, vegetables, chemicals, fertilizers, and consumer packaged goods. The different models include:
