The production of paper cups, for example for \"coffee to go\", is literally a \"hot thing\". High temperatures are generated inside the machines in the cup moulding units due to frequent acceleration and deceleration. Michael H\u00f6rauf Maschinenfabrik GmbH & Co. KG has found a solution to the temperature problem with the help of Yaskawa. In machines of the \"BMP 100\" series, GA700 frequency inverters significantly reduce the mechanical loads on the drive technology and the resulting temperatures.<\/p>\n

The Michael H\u00f6rauf Maschinenfabrik GmbH & Co. KG<\/strong> from the Swabian town of Donzdorf is in the Packaging technology<\/strong> specialises in machines for the production of paper cups and containers. In addition to high-end machines for the rational Production of paper cups<\/strong> customised solutions for branded companies for the in-house production of Packaging made from paper composites<\/strong> developed.<\/p>\n

The machines from the BMP-100 series are designed for Production of single-wall beverage and packaging cups<\/strong>. The \"BMP 100 Super\" model is suitable for producing up to 160 large-volume packaging cups per minute, which can later be filled with snacks, pasta, ice cream or popcorn. The \"BMP 100 Compact\", on the other hand, can produce up to 180 cups per minute for hot and cold drinks. Both machines process cut segments of paper and paper composites as well as roll material.<\/p>

Drive elements get too hot for paper<\/h2>\n

The centrepiece of the machine is the Moulded cup unit<\/strong>. This is one with Core mandrels<\/strong> equipped with a so-called star. It has a diameter of around one metre. These core mandrels are rotated in front of the various processing stations. Among other things, the paper for the cup wall is fed in, moulded and glued, the base element is integrated and the top edge of the cup is formed.<\/p>\n

With maximum 180 cycles per minute<\/strong> the star must be accelerated and decelerated very frequently. This mechanically very demanding drive task is performed by an asynchronous motor.<\/p>
