BISCUIT PRODUCTION
In the first step of the packaging process, pick and place robots collect one, two or three biscuits at a time with gripper tools spe- cially adapted to the product, and insert the stacks to the right and
and that they are packaged as sustainably as possible. When Hellema set out to find a new packaging machine,
that would be able to process its wide range biscuits, with different fruit and chocolate fillings, from bare product to final packaging, it wanted a flexible solution that could quickly change formats and materials to allow it to meet the needs of different customers. The chosen packaging solution was also required to pack as sustainably as possible by avoiding rejects and saving materials, and all in a limited space on the production floor. “The new packaging machine had to fit into our production hall and be designed in such a way that our employees would have easy access to individual line sections,” confirmed Hille. Schubert was able to offer a flexible packaging solution for both the primary and secondary packaging of the biscuits. It consists of Schubert’s flow-wrapping machine for primary packaging, as well as a combined cartoner. Different biscuits in a variety of flavours are processed on the new top-loading line. The products are first packed into flowpacks as individual biscuits or in stacks of two or three. In the cartoner, the flowpacks can then be packed either into cartons with attached lids or into single- or double-layer multipack flowpacks.
The entire packaging line is 72m long and incorporates every available standard component group from Schubert’s portfolio. The line is designed entirely without interfaces,

and guarantees flexibility and performance, as well as reliable and cost-efficient production. It also enables quick format changes without interrupting production. In a first step, the biscuits enter the machine on the product conveyor. Image processing with 3D scanners carries out the first important quality check upstream of the pick & place station so that the pick & place robots only pick up good quality products. With gripper tools specially adapted to the product, the robots collect one, two or three biscuits at a time and place the stacks to the right and to the left of the product conveyor into the feed chains of a fully-integrated flow-wrapping machine. The biscuits are then packed into flowpacks. Ultrasonic longitudinal sealing and Schubert’s flying cross-sealing unit ensures flawless and secure sealing for both conventional and recyclable films. The pick & place robots control the speed of the feed chains depending on the product flow to ensure that each segment in the infeed chain is filled with biscuits and that no empty or incomplete flowpacks leave the line. Using the counterflow principle, the biscuit packets are then packed either into cartons or into multipack flowpacks. “The new packaging line is a real asset for us,” concluded
Hille. “We can now offer different packaging materials as well – for primary packaging, from monofilms to aluminium- laminated films, and for multipacks, composite plastic films and paper-based films.”
