Integrating Checkweighers Into Factory Control Systems

Hardy’s Dynamic Checkweigher line uses control systems that fit customer processes, eliminating overfills and offering easy operation at a low cost of ownership.

Built-in visualization tools eliminate the trial-and-error of product set-up, enabling operators to capture the entire checkweighing process and display results on the machine’s HMI screen.

Successful businesses listen—and respond—to their customers.

Clearly that’s exemplified by Hardy Process Solutions, a Roper Technologies company and provider of process weighing and packaging solutions. Hardy believes that weighing machinery should be easy to integrate, maintain, and operate, delivering the lowest cost to own for its customers.

A good example of this is the Hardy Dynamic Checkweigher line, available in S Series (Small), I Series (Intermediate), C Series (Chainweigher) and Dynamic L Series (Large). Introduced in March 2017, the Dynamic units provide fast, precise determination of an object’s weight while that object is in motion.

The checkweighers diagnose and reduce overfill rates through process optimization with filling machines. They can be integrated into a customer’s factory control system via Rockwell Automation’s FactoryTalk® analytics program. Why did they select Rockwell Automation?

“They dominate the North American market, so we selected components that our customers are familiar with and can easily integrate into their existing manufacturing systems,” explains Timothy Norman, Hardy’s Project Management, Business Development. “The components are also available from hundreds of Rockwell distributors throughout North America for easy servicing.”

Three key benefits

Hardy’s Dynamic Checkweigher works in virtually any industry that ships discrete products. For medical applications, the machinery can determine if the contents of a packaged procedure are correct—for example, confirming that the kit contains one catheter, one instruction pack and one accessory pack. In the pharmaceutical industry, the Dynamic can verify that a bottle contains the correct number of pills.
