Sweet fruits efficiently packaged

Tradition and innovation

The year 1893 saw the outset of the history of the jam and candy factory Franz Zentis. A company operating worldwide developed from a colonial goods and grocery store on the Adalbertsteinweg in Aachen, Germany. Today, the ZENTIS GmbH & Co. KG has about 1,300 employees in Aachen and had a turnover of 600 million Euros in 2006. With a fruit treatment capacity corresponding to an output volume of several hundred tons a year, ZENTIS is considered to be one of the largest fruit-processing companies in Europe.

Today, the company's range of products is subdivided in three categories:

  1. The production of a wide range of high-quality jams and sweet creams for the end consumer.
  2. The production of candy products and confectionery, high-quality marzipan and chocolate products.
  3. The production of fruit preparations for the dairy and bakery products industry.

The project - automation of palletizing

For palletizing the finished products in the jam and spread section, ZENTIS decided to replace the out-of-date 3-axis set packing system by a new robot plant by Kawasaki.

An important motivation for this decision was the precipitous increase in the variety of products and of jar forms. Here, Kawasaki robots offer enormous advantages by their fast tool change.

Hence, changeover and dead times can be minimized. ZENTIS has four packaging lines in which Kawasaki robots of the FS45N type are used for small containers and one ZD130S robot is used for palletizing buckets.

The technology

Kawasaki robots of the F series excel by high speeds as well as by a light and slim arm design with load carrying capacities from 3 kg to 60 kg.

By the incorporation of high-performance servomotors and highly efficient step-down gears, the maximum robot speed could be increased and thus a reduction of cycle times was possible.

Furthermore, the floor space required by them is very small and they have a slim profile.

The arm with its extremely slim design and without compensation structure makes possible designing compact working cells. The smooth contours of the robust hand articulation permit to attach external cables and hoses without any problems.

All models are mountable on the floor and on the ceiling and most of them also on the wall.

Roboters in use

Kawasaki Palletizing RobotFor packaging, the finished jams and spreads are transferred in parallel next to the packing boards on conveyor belts of the palletizing station. An inlet mask centers the jars and brings them into the correct position. After aligning, one lot each is sucked in by the Kawasaki robot and placed in trays for 10 or 12 jars accurate to the very last millimetre. 

The entire plant is controlled by a central network enabling quick access to all robot functions. Minor program changes or corrections, reading out service data or creating system backups will be done quickly and easily. The Ethernet interface required for this is standard in all Kawasaki robots and already integrated into them on delivery.

"The new Kawasaki robot plant is instrumental in increasing production efficiency", says Frank Werth, responsible for the technical support for this ZENTIS plant.

Robots by Kawasaki have been in use with ZENTIS for 14 years already and have rendered their service smoothly and without any problems and in this period. Moreover, this is the motivation for purchasing further robots by Kawasaki in future.
