Electronic cams avoid production slow-down even when product is changed
Italian packaging machine specialist, Clever, recently developed a heat-shrink sleeve applicator using a film cutter on electronic cams.
Compared to conventional solutions - where mechanical cams are used - this electronic architecture allows operators to change product and format without reducing production speed, simply by setting the pitch of the feed screw and the length of the film.
One of the first systems to be delivered was designed to operate in a continuous cycle (without stopping to replace the film) at 14,000 bottles/hour per head. The system uses an Omron NJ-Series Machine Controller which provides exceptional flexibility, enabling operators to modify both the label application phase on the bottles as well as the cutting phase.
Importantly, PID internal learning inside the PLC is used to adjust all parameters automatically. Andrea Parlato, a technician at Clever said.
“Normally, you would need days to adjust the PID. But this solution does it automatically and allows the PID to be adjusted directly in the customer’s work environment.”
