The perfect pretzel with robotics

The food industry is one of the strongest growth markets for the automation sector. Robots fill pizzas, portion cheese, sort, pack and palletize. Trapo shows how automated solutions reduce sources of error and ensure high quality, short cycle times and consistent availability.

Symmetrically twisted strands of dough, thin arms and a thick belly - the production of pretzels used to require precise manual work. Today, fully automated baking lines produce identical dough loaves every second. Cameras and industrial image processing provide valuable support here: they are used to determine the coordinates of different pretzels and robots use a titanium knife to cut the perfect slit depending on the thickness of the dough so that the dough does not burst open - for consistent, high quality.

Combination grippers enable short cycle times
Combination grippers combine the functions of vacuum, fork, magnetic and mechanical grippers. They adapt to different product sizes and also grip pallets, workpiece carriers, intermediate layers or lids. Combination grippers therefore optimize the possible applications as well as the range of functions and performance of robot systems - from articulated arm robots to gantry robots and picker robots. In addition, the time-consuming and costly changing of grippers is no longer necessary, thus speeding up cycle times.

Layerpalletizers for gentle and precise layer formation
Snacks such as wafer slices have to be packaged in secondary packaging of different sizes. High-performance layer palletizers are capable of operating one or more palletizing stations as required, depositing objects cleanly and creating any number of layer patterns in different formats at high speed. High cycle times of up to ten layers per minute can be achieved. In the infeed area, flexible, omnidirectional tables or kinematic systems are used as a preliminary stage to palletizing for gentle layer formation.

Autonomous transport systems for flexible material flow
In contrast to rigid conveyor technology, driverless transport systems enable flexible, in-house transportation of goods. They can transport loads of up to 2,000 kilograms and also unfold their full benefits in the beverage industry, where the material flow is characterized by high quantities of uniform and easily stackable goods. In the prevailing block storage systems, autonomous transport systems easily take over the direct storage and retrieval of goods. With the help of vertical conveyors, they can also operate across different levels.

"In addition to accelerated intralogistics processes, optimized food safety is a key benefit of automated food processing," explains Jörg Thomas, Head of Sales at Trapo. "In many cases, people still represent the greatest hygiene risk in operational practice. Housings and control panels made of stainless steel are resistant to corrosion and acids, even when using chemical cleaning agents. They can be cleaned and disinfected quickly and safely. In this way, automated solutions that comply with hygienic design ensure operational safety for manufacturers in the food industry and safeguard their competitiveness." as
