Upgrade delivers faster changeovers

Upgrade delivers faster changeovers

Following a customer request to trial an RF wireless electronic position indicator system, machine and production line manufacturer WestRock Linkx has now adopted the system as a standard option across its range.

WestRock Linkx Systems manufacture machines and integrated lines for shelf-ready packaging. Solutions include BoxSizer automatic and semi-automatic warehouse dispatch 3PL ecommerce packaging lines. It also manufactures labour saving semi-automatic re-packaging solutions for contract pack and 3PL companies.

A visit by a customer to the PPMA show introduced Elesa’s RF wireless electronic position indictor system. The customer subsequently asked WestRock Linkx to trial this system in order to speed up machine changeovers while ensuring reliable, repeatable accuracy. It proved to be a like-for-like fit in place of the position indicators previously installed. This enabled faster re-sets by use of an automated controller via the machine PLC, reducing operator time and operator error.

Customer satisfaction was high across a range of machine installations leading to an end user comment that “this cost-effective upgrade was added to our machines in under two days, and has already made huge improvements to product change overs and set-up times.”

The team at WestRock Linkx was likewise impressed Tom Whatling, technical sales manager, explained: “The Elesa wireless electronic positioning system enables faster and more reliable machine setup by use of a wireless connected profile controller, which displays the initial setup values on each of up to 36 electronic position indicators.

“The system is now a mainstream option on all our machines and can be retrofitted to our installations – even to other manufacturer’s machines where we are upgrading a complete facility.”

Elesa’s RF electronic positioning system enables quicker and more reliable machine set up by use of a wireless connected profile controller, which displays the initial set up values on each of up to 36 electronic position indicators. The operator can simply choose the appropriate menu then quickly re-set each spindle to its correct start position and the machine is good to go. This saves time and takes out much of the possibility of human error. Elesa DD52R-E-RF position indicators are networked to the UC-RF control unit by radio connection thus enabling an easy and quick installation. Current and target positions are transmitted by RF to and from the control unit, facilitating rapid machine set up.

The system consequently saves time during the format alignment process. Once the setup profile has been called up by the PLC, the control unit UC-RF transmits the target position to each DD52R-E-RF position indicator. The current/target position is displayed on the LCD of the DD52R-E-RF. The operator manually sets the position of the spindles following the arrow displayed on the LCD (clockwise/counter-clockwise rotation). Once all the spindles are correctly set, the UC-RF control unit communicates to the PLC of the machine that the setup has been completed – the system prevents the start of the machine until the set-up has been completed, for safety reasons and to prevent loss of production from incorrect settings.

The UC-RF controller can network with up to 36 position indicators and is compatible with PLC Interfaces: RS232, RS485, Ethernet/IP, Profibus and Modbus. The DD52R-E-RF (IP67) position indicator 6-digit display mode can be selected by the operator.
