A Cannon Machine for Chemnitz University of Technology
THE PROFESSORSHIP LIGHT WEIGHT STRUCTURES AND PLASTIC PROCESSING( SLK) AT CHEMNITZ UNIVERSITY OF TECHNOLOGY, UNDER THE DIRECTION O F P R O F E S S O R LOT H A R K R O L L, ESTABLISHED ITSELF IN THE LAST YEARS AS ONE OF THE LEADING LIGHT WEIGHT INSTITUTES IN GERMANY. WITHIN THE FRAMEWORK OF THE“ CLUSTER OF EXCELLENCE MERGE”, NATIONWIDE THE F I R S T A N D O N LY C L U S T E R O F EXCELLENCE IN THE FIELD OF LIGHT WEIGHT-CONSTRUCTION RESEARCH, THE MERGE TECHNOLOGY CENTRE WAS FOUNDED IN 2015 AT THE CHEMNITZ UNIVERSITY OF TECHNOLOGY. RESEARCH IN BASIC TECHNOLOGIES FOR RESOURCE-EFFICIENT PRODUCTION OF LIGHT WEIGHT-STRUCTURES WITH HIGH POWER- AND FUNCTION DENSITY IS CARRIED OUT IN A HIGHLY MODERN RESEARCH-BUILDING WITH MORE THAN
2
3,500 M OF SPACE.
Especially for the production of small Composite parts and thin lacquer coatings Cannon Deutschland was assigned to deliver a mobile 2-component dosing machine type A-Lab 20, speci ically designed for laboratory use. The task was clearly de ined – lexible use, dosing of small quantities, and fast change of materials without extensive rinsing. The Cannon A-Lab 20 provides the following features and advantages to its users:
· Small chemical volumes, saving raw material costs both for use and disposal.
· Smart components circuit, for a clean workplace.
· Easy change of materials, allowing for multiple trials in a short period of time.
· Compact design, in combination with a movable wheeled chassis, saving lab space.
Two component tanks with a volume of 16 l and adequate drain valves for material exchange characterise the laboratory machine, that otherwise features a circuit and a con iguration fully comparable to the“ big” dosing units. Two small Cannon axial piston pumps with variable output, adjustable by hand wheel as well as additional frequency drive, ensure a reliable and precise dosing of components. Maintenance works are reduced to minimum due to the installation of a magnetic coupling at both dosing pumps, which also ensures the required cleanliness. The Cannon FPL 7 HP mixing head showed that it is ideally suited for smaller dosing amounts. A 3 m hose package with electrical heating, as well as pressure- and temperature- measuring instruments close to the mixing head, ensure a safe and precise working atmosphere and reliable monitoring of the relevant parameters. Cannon OVS for Process Data Visualisation, in combination with Cannon MD Link for data-archiving, offer reliable comfort for data processing in the laboratory work. The Siemens PLC of the latest generation enables reliable function, while a Siemens Touch Screen Operator Panel with a 7” display is used to interface the machine with the operator( MMI). Monitoring of all parameters, as well as the comparison between SET and ACTUAL process values is carried out once per millisecond. Initial test of the so-called“ looding” of a thermoplastic component, carried out in a nearby injection moulding machine with Turnover Board( external brand) already achieved the best results. The irst step for a prosperous partnership between the Chemnitz University of Technology and Cannon Deutschland was successfully accomplished. Both parties are gladly available for further projects and suggestions.
