In 1934, the idyllic surroundings of Toggenburg witnessed the emergence of the cornerstone for the well-known Swiss wafer specialities. Otto Kägi founded a company under his own name, initially producing various types of biscuits and then, from 1958 on, a milk chocolate coated wafer with the brand name Kägi fret. Over the years, this product developed into a Swiss institution and ensured the company’s steady growth. Today it employs over 80 associates producing more than 3000 tons of wafers and biscuits per year.
The cooperation between Kägi Söhne AG and Bosch Packaging Systems has a long tradition, and for this project the wafer producer again put its trust in the quality of the machine manufacturers from Beringen, Switzerland.
Flexibility comes first
For a product such as Kägi fret, which is exported in a variety of formats to many different markets, a quick and simple format changeover is key. The TTM’s simple fail-proof format changeover concept, the technical highlight of the system, fulfills this requirement.
The solution realized with Kägi handles up to 400 wafers and 20 boxes per minute. The modules for carton transport and product grouping can be changed easily and quickly, a feature which becomes increasingly important the more formats are produced, requiring even more frequent changeovers. In view of its broad range of pack styles, the toploader is being utilized for loading externally erected boxes, for feeding a multi-pack line and for loading an additional outfeed unit for the manual packaging of special seasonal formats.
Manifold fields of application for Sigpack TTM
The Sigpack TTM was first presented to the market at Interpack 2011 as part of Bosch’s new bar packaging line. The new toploading platform from Bosch Packaging Systems offers integrated as well as stand-alone solutions for up to 150 boxes and 1000 products per minute. The line configuration is based on functionality and a modular design and features scalable performance of both product infeed and box outfeed.
The Sigpack TTM is compact and requires minimal space, but the machine also convinced Kägi with features like its toploader cell concept with integrated control cabinets. The toploader works with a 3-axis robot suspended from the top, thus ensuring a flexible choice of packaging style for future applications, such as a change from loading flat-lying products to loading upright products.
With its new secondary packaging system from Bosch Packaging Systems, the Swiss company sees itself well prepared for the future as Production Director Hans-Peter Scherrer explains in a conversation with the author.
