The challenge

The times of cookies being formed by the hands of busy Christmas elves came to an end long ago. Today mass production is a reality in the baking industry.

As for the Schmidt cookie manufacturer in Nuremberg, containers with cookie mixtures are pushed to filling stations where the individual ingredients are added to the mixture.

It is the workers’ responsibility to move the appropriate containers towards the individual filling stations and to measure the ingredients according to the recipe. Equally, various kinds of cookies are produced in parallel cycles.

Problems occurred when individual ingredients were measured inaccurately or added several times. These mistakes are especially happening  in the food industry where recipes have to be strictly observed in order to maintain a continuous high quality standard of all products.

The implementation

An identification system based on Transponders minimizes the number of mistakes without completely automating the production process. Existing machinery does not need to be replaced by new equipment.

Transponder technology is an especially optimal appliance for the food sector as filthy conditions do not have any effect on its performance.

At the start of the production cycle the transponder fixed on a specific container obtains detailed information on the charge of the container. As before, the worker accompanies the container all the way through the individual production stages where the data stored on the transponder will be read via fixed transponder reader or via portable manual terminals.

The data are processed by the central workstation where all reading stations and terminals are connected to. Information for the operating personnel is transmitted on a display at the filling stations providing the information required for the particular charge to make sure that the required ingredients will always be chosen.

Scales have been mounted beneath some filling devices where the container is moved to by the workers in order to obtain the specific ingredient quantities. Therefore, the control panel can automatically handle the tricky measurement of the individual ingredient quantities. As a result, wrong fillings and containers with faulty material are things of the past.
