Each line takes the products arriving from its respective oven and conveys them to two flow pack packaging machines. The innovatively controlled buffering system placed between the oven and the packaging machines increases the production efficiency of the entire line. This conveying system is comprised of a series of belts which control the flow of the product. The system is used to decouple the upstream flow, which is linked to the productive capacity of the oven, from the downstream operation, which is the working speed of the packaging machines.
“With Schneider Electric as global supplier for the control movement we have been able to reach performances higher than our competitors at a reasonable cost, with unquestionable advan- tages in terms of time reduction for the testing and commissioning of our lines” states Valerio Travaini, responsible for the software develop- ment of the robotics division in Cavanna. “Up to the date, an ever increasing number of custom- ers want to include in their machines specifications the PacDrive integrated control systems.” This confirms not only the effectiveness of the product itself but also Schneider Electric’s capa- bility to supply complete solutions for the pack- aging world everywhere in the world!
One of the four lines uses two robotic cells. Each cell is comprised of eight delta style kinematic robots, each robot working at a speed of 90 cycles/min. The whole equipment was built using Schneider components.
Inside the control cabinets there are Phaseo power supply devices and 12” wide touch panel series Magelis with high visibility screen. The product transport lines are equipped with AC motors and driven by Altivar frequency inverters. Where precise motion control is a must, like on the robots and on the packaging machines, the PacDrive iSH system, dynamic brushless motors with integrated servo drives, are used.
