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 .
