Dynamic Check Weigher Series

Dynamic Check Weigher

High Performance Dynamic Checkweighing

Open-Source, Off-the-Shelf Rockwell Components, Seamless Integration into Connected Enterprise

Hardy's Dynamic Series of checkweighing machinery is built using off-the shelf components, with controls based on a Rockwell Automation's CompactLogix platform, providing a standardized open source architecture that is flexible enough to meet both current and future control needs.

Weight processing is managed by Hardy’s HI 4050CW weight controller. Sampling weight data at 4,800 times per second, the HI4050CW is capable of providing enough weighments to accurately categorize packages weighing from 5g to 225kg at speeds up to 350 packs per minute.

OPEN ARCHITECTURE

Hardy Dynamic checkweighers are built using a Rockwell CompactLogix® platform running Studio5000® making them the easiest to integrate, upgrade and modify. The GUI uses FactoryTak View software, giving the user the ability to share and modify information presented on the machine’s HMI to the larger Connected Enterprise®. Extra onboard I/O and the ability to expand the rack provide a future proof control platform that is ready to accommodate additional upstream and downstream closed-loop controls, as well as peripherals such as metal detection and x-rays.  All data tags are available to Enterprise wide software. 

MOTORIZED DRIVE ROLLERS

Gearing and motor are integrated into the roller. Extremely efficient with no exposed moving parts, motorized drive rollers are available in a variety of speed and torque ratings so they can be tailored to the specific requirements of your application. Available in stainless steel the series is rated for IP66 wash-down environments. Smart drives eliminate the possibility of over-torque or binding that could cause motor or belt damage, creating a safer and higher reliability conveying system.

QUICK CHANGES

Belts can be removed, inspected, replaced and cleaned without the use of tools. A simple cam-lock secures belts in position and at the correct tension – making change-overs fast and easy.

SOLID CONSTRUCTION

The Dynamic C, S and I series are built using welded Stainless Steel tube construction, created a very ridged and long lasting frame that will withstand even the most abusive environments. Built to handle virtually every product in any environment, only simple modifications are required to change bed widths and lengths. The Dynamic L series is designed for very heavy packages and therefore is constructed of steel channel.

EASE OF SETUP & CALIBRATION

Intuitive menus presented on a large Allen Bradly PanelView Plus® HMI provide a comfortable environment for setting up product recipes, tuning the machine for optimum performance and setting up the scale system. Use Hardy's exclusive C2® for automatic scale calibration.  Use the Internal Trigger mode and eliminate the need for a photo-eye.

FULL STATISTICS & DIAGNOSTICS PACKAGES

The Diagnostics Section allows users to visualize the process and make adjustments.  This saves so much time over the guesswork that is required with other checkweigher machinery.

All the process performance statistics are calculated and available on the network. Because the machine is open source,  use the data to optimize your process upstream.

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 Hardy Dynamic Checkweigher features the following Toolbox technologies:

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+ adds two patent pending adaptive filtering algorithms that decrease the time that the HI 4050CW displays accurate, stable rate readings by a factor of three.

C2®  Electronic Calibration
The Hardy C2® core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.

INTEGRATED TECHNICIAN® Operator Diagnostics
Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.

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.

CHECK-MASTER
CHECK-MASTER is a set of software tools that support check weighing functions and are part of every Hardy Check Weighing solution. There are tools for both static and dynamic check weighing.
