Hardy Caseweighers

Caseweighers are a fully automated scale system designed to continuously weigh items while in-motion. The Checkweigher controller can communicate seamlessly both upstream and downstream across the Connected Enterprise Network when built with an Allen Bradley CompactLogix™ PLC or via an optional EtherNet/IP connection when built with an IDEC Platform.

New Hardy Caseweigher for Product Inspection

Designed for Simplicity  and Robust Flexibility

Hardy’s all New Caseweigher machine is designed for SIMPLICITY using off-the shelf components and a PLC control platform to afford users enough FLEXIBITY 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 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.

Open Source
Hardy Caseweighers are 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 in both Allen Bradley and Idec PLCs.

Off-the-Shelf 
Simple design and minimal use of custom parts. Controls 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 you control network by addressing the equipment thru 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 & error process of product set-up, enabling operators to capture the entire checkweighing 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 off-set calculation, statistics package and Hardy weightless C2 calibration are all standard features with every machine.

Hardy Process ToolboxHardy Process Toolbox

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency or reduces risk in process weighing applications, including WAVERSAVER® to eliminate vibration, C2® electronic calibration and Integrated Technician® to name just a few.

The HI 4050 features the following Toolbox technologies:

C2® (or eCAL) Electronic Calibration
The Hardy C2® (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.

WAVERSAVER® vibration eliminator
Hardy's WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.

WAVERSAVER+
A patent pending dynamic algorithym that improves the stability of static weight readings by 3X

Embedded Web Server
Access your instrument from any computer browser, easing setup and making diagnostics fast and easy.  Use the Embedded Web Server to set up all parameters from anywhere on the Ethernet network.

Secure Memory Module Stores Configuration Data
Hardy's Secure Memory Module (SMM) uses a standard SD card to automatically back up critical weighing system data, and allowing you to transfer it to another like controller in a few minutes.  You can also use the card to easily back up your controller data onto a PC.
 

First, using Throughput Tables below, determine the minimum bed length required to achieve desired throughput (UPM). If package size is not listed, round up to the next nearest size. NOTE: the in-feed conveyor speed must match conveyor speed found in tables to ensure proper operation.

Second, verify package width does not exceed bed size selected.

 Throughput Tables

Conveyer Speed Stated in FPM – Feet Per Minute

It is the responsibility of the customer to deliver the products spaced and at infeed speeds as stated in the above tables to achieve optimal equipment and stated accuracies. Please contact your local representative to discuss additional material handling solutions available to ensure infeed speeds match required checkweigher conveyor speeds to achieve desired throughput. Only one product can be on the checkweigher at a time. For example,when running a 12” product across a 24” long lonveyor – the pitch must be greater than 24”, the gap must greater than 6”.
