New multihead weighing system for the ‘smiling child’ – Product mixes consisting of up to four components
Anyone who thinks of biscuits today thinks of 'Brandt' and the smiling child on the orange colored package. Brandt Zwieback-Schokoladen GmbH, the successful business founded in 1912, purchased a four-component MULTIPOND multihead weighing system of the type MP 2001-FFC-S5R to optimize its three-shift operated packing process at its Landshut site and was able to reduce its waste almost to zero as a result.
The company currently employs around 900 staff at 4 locations in Germany. With a share of more than 80% Brandt is the market leader in Germany and distributes its products - six million biscuits per day alone, crispbreads and chocolate - throughout the world. In the chocolate market, however, the company does not only produce under its own brand but regards itself here more of a B2B (Business to Business) specialist. This means that Brandt produces in this sector seasonal items among other products for well-known companies.
The background to the procurement of the MULTIPOND multihead weighing system was the weighing of a four component mixture (60 weighings per minute) consisting of four different wrapped chocolate bars, with the challenge being the small quantity of two items for each component. Brandt's basic requirement was to eliminate any inefficiency due to over feeding of product, bearing in mind that only two pieces are required per component. MULTIPOND succeeded in finding the right solution for precisely this application by developing the new S5R model.
The concept is based on a standard twin memory hopper weigher. The outer memory hopper is replaced by a second pivoting funnel which can either deposit product into a `good combination` or alternatively divert it to a reject position. Using this solution there is no loss in weighing efficiency as rejects are evacuated on an individual head basis whilst the rest of the weigher can continue weighing resulting in no missed cycles.
In addition, the shortest changeover times were demanded by Brandt. With this in mind, another requirement was for the weighing system to be operated with up to four different components as well as with a single product. As a result the weighing system can be utilized for the entire Brandt range. If the weighing system is operated with a single product, it is possible to use only one or two sub-segments of the weighing system in order to keep cleaning time as low as possible.
''Because of the overall design of the weighing system, meaning smooth surfaces on the product contact parts, low angles of inclination at the chute/hopper unit and an integrated impact protection curtain in the hopper, even fragile products can be weighed gently'' according to Thomas Huber, Technical Manager. MULTIPOND's experienced engineers have installed the weighing system on site and set it up in such a way that smooth running of the entire packaging process is guaranteed. All recipes are stored in the weighing system's memory and can be readily called up by the operators. As a result, expensive operation training courses were not necessary and product changes are simple and smooth.
Thomas Huber, Technical Manager at Brandt in Landshut, was extremely satisfied with the implementation of the entire project: ''MULTIPOND successfully met all our requirements. It was clear to us that we could not procure an 'off-the-shelf weighing system' for this application, but would need an individual solution for it. For this reason we decided on a weighing system from MULTIPOND as the company specializes in custom built machinery. As a result, the ideal machine was designed for our application based on the closest of cooperation.''
MULTIPOND is the sales and service division of the German based manufacturing company ATOMA which has been established since 1946. The first automatic weighing system for the packaging industry was launched in 1963. It is positioned as the market leading innovator in the design and manufacture of customized multihead weighing systems for the packaging industry. Headquarters and manufacturing facilities are in Waldkraiburg, Germany, about 65km east of Munich. Beside the global network of sales and service representatives, there are four wholly owned sales and service subsidiaries in the UK, the Netherlands, France and the US.
