On the new Schubert cartoner, Tören’s wafer biscuits, already packed into flowpacks of various lengths, are packaged into boxes with attached covers. The cartoning machine features Schubert’s proven compact yet flexible layout and consists of three sub-machines: an carton erector, a filler and a closer. The carton blanks are fed via a recently designed vertical magazine, into which the blanks are freely stacked on top of each other. A belt moves out of the packaging machine into this stack, picks up a small quantity of cardboard blanks and places them into an intermediate buffer.

The blanks are individually removed from the intermediate buffer from below using a vacuum and transferred to a pusher, which transports them past glue nozzles to a folding box. There, a plunger sucks up the glued blanks again, presses them through the folding box for erection and places them onto a vacuum conveyor for onward transport to the filling station. Adnan Akman, Sales Account Manager at Schubert, adds: “Cartoning machines with this output typically include a multi-lane erecting process. With the new A3 erecting unit, however, we succeeded in designing a packaging machine with a single-lane erecting process. As a result, fewer robot units are required, which makes the solution’s design more cost-effective overall. Nevertheless, the packaging system achieves the same output as multi-lane erectors. We are immensely proud of this result.”

The A3 erector also offers Tören the desired flexibility: if new formats are run on the packaging machine, a new magazine is not required, as the A3 erector’s vertical buffer accommodates a wide variety of carton blanks. Only the folding box and the plunger for erecting need to be replaced.
