The remarkable functionality that servo motors bring to packaging machinery was on display at interpack, and nowhere was it more forcefully demonstrated than at the Loesch Pack booth. On full display was the RCB-HS, which wraps small chocolate products in a way that combines a hermetically sealed pack style with a traditional fold-wrap look. Olaf Piepenbrock, Managing Partner of parent company Piepenbrock, calls it “unique in this segment.” The magic behind the machine is in the control cabinet, which houses 12 Lexium 62D servo drives and a PacDrive controller from Schneider Electric. Each of the 12 drives is a double-axis drive, so each one governs two rotary servo motors out on the machine. The net result is a premium look and a hermetic seal at 600 bars/min.
Elsewhere at interpack, it was linear servo motors that commanded the attention of show goers. No matter which technology supplier they come from, these devices all rely on multiple independently controlled and magnetically propelled movers on straight or curved paths.
