The result is that fewer robot units are needed, which makes the machine design more cost-effective while achieving the same output as multi-lane erectors. The wafer biscuits, packaged in
flowpacks, proceed from two flow- wrapping machines, and enter the line in two lanes in two grouping chains. From there, a robot picks them up and places 2 x 12 pieces vertically onto the grouping table. There, the flowpacks are pushed together to form a layer of 12 units per box. A second robot picks up the two layers and places them into the boxes on the vacuum conveyor. In a final step, the boxes, which have an attached lid, are closed, and removed from the system. The bespoke solution was designed with wafer biscuits. Mehmet Tören explains: “The confectionery market is very fast-moving. And if a product, such as our wafer biscuits, is well received by customers, they often expect multiple product variants. It was extremely that allows format changeovers to be conducted quickly and easily.” Four different products are packed into 24ct cartons, and one product is also packed into a 12ct carton. The cartoner packs 660 products per minute – or up to 55 cartons per minute.
flexible solution for its wafer biscuits. Tören exports a range of chocolate wafers, puffed snacks and chocolate bars to 50 countries. To package its many products and machines from Gerhard Schubert. The latest turnkey solution created by Schubert sees Tören’s wafer biscuits, already packed into flowpacks of various lengths, packaged into boxes with attached covers. The cartoner features a compact yet flexible layout and consists of three sub-machines – an erector, a filler and a closer. The carton blanks are fed via a vertical magazine, into which the blanks are freely stacked on top of each

other. A belt moves out of the 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. Working closely with Tören, Schubert succeeded in designing a machine with a single-lane erecting process instead of the more usual multi-lane erecting process.
It is important to understand the extra service and engineering expertise that should come with a bespoke solution. For the busy confectionery manufacturer, it can offer a good solution, enabling the in-house engineering team to get on with addressing the day-to-day needs of the existing plant, leaving everything relating to the new plant to a trusted partner who should handle everything from design through to commissioning and integration of the new plant into the existing factory. Once the keys to the new system have been handed over, the partnership should not end, the provider should still be available to help with training operators to work with the new plant and should be available to help with any maintenance issues throughout the lifetime of the plant. This can be invaluable for confectionery manufacturers today who need to focus their attention on ensuring the consistent quality of the end product. are, thanks to enabling a richer dialogue across the supply chain.
