Caseweighers Provide Simple and Effective Quality Inspection

Caseweighers Provide Simple and Effective Quality Inspection
Delivering what companies promise customers in terms of quality and quantity in their packages requires close and continuous monitoring during the product inspection process; this monitoring is often done using weight data to determine how they are delivering against their promise.

100% product inspection can help bridge the gap for a manufacturer having to choose between manufacturing efficiency and lowering the cost associated with poor quality.  Another consideration is the ability to meet regulatory requirements designed to protect consumers. In certain industries such as pharmaceuticals, check weighing can help ensure that exactly the correct numbers of pills are in a container.

Hardy’s new Caseweigher machine is designed for product inspection simplicity using off-the-shelf components and a PLC-based control platform to afford users enough flexibility to meet both current and future control needs.

At the heart of the equipment is Hardy’s Checkweight controller sampling at 4,800 times per second to provide extremely accurate and fast weight data for packages from 1 to 50 lbs at speeds up to 60 updates-per-minute.

Featuring a large touch screen HMI display, operators can easily navigate between different product recipes or adjust machine set-up parameters. The open frame is constructed of a durable round tube that is available in either painted or stainless steel.

Maintenance-Free motor drive rollers further eliminate complexities typical of chain or pully conveyor drive systems.

Hardy Caseweighers is built on a PLC platform – making it easy to modify the machine program to accommodate current manufacturing & data requirements, yet flexible enough to meet future needs. Customize the HMI to show information important to your process. Available with control options of either a Rockwell Automation Allen-Bradley 1769 PLC or with Idec PLC standard controls.


Build in the USA, with a modular equipment design and with an ongoing commitment to maintaining parts inventory, Hardy can respond rapidly to customer needs. While Hardy maintains stock of popular machine models, producing equipment in days instead of months is a testament to the effectiveness of “Designed for Manufacturability” principles applied during the development stage.  Furthermore, Hardy tests customer products on the actual machine before shipping to not only ensure that it’s the right equipment for the application but also to allow customers to put the equipment into production within hours of receipt by pre-loading recipes and tuning the equipment beforehand.

Controls are built using readily available components such as the PLC, HMI, and Power Supply – making replacement, emergency repairs, or upgrades quick and easy. Plenty of spare I/O and the ability to expand provide a future proof control platform.

Seamless Integration

Machine communications over an EtherNet/IP® backbone make integration quick and data exchange simple. Serve up process statistics, manufacturing performance, and machine status to your control network by addressing the equipment through one of the spare Ethernet ports available or add a network switch to tie in additional peripherals such as printers, bar code reads, or vision systems. Use readily available real-time data to optimize upstream processes or create closed-loop control by exchanging tags with another device on the network.

CheckMaster Software

Built-in visualization tools eliminate the trial and error process of product set-up, enabling operators to capture the entire check weighing process and display it on the machine’s high-resolution screen. Quickly and easily determine the perfect set of parameters to maximize weight capture time and optimize for repeatability and accuracy. Real-time accuracy (3-Sigma) tracking, automatic offset calculation, statistics package, and Hardy weightless C2® calibration are all standard features with every machine.

Measuring the improvement of manufacturing efficiencies using product inspection is straightforward. The reduction or elimination of overfilling or underfilling as a standard process helps companies deliver what is promised to customers. This directly results in the accurate use of raw material to guarantee delivery against that promise.
