As a major global producer of specialized adhesives for labelling applications, Avery Dennison invests continuously in the improvement and optimization of its products. To support the company’s research into the stability of a specific type of resin, Avery Dennison asked Suurmond whether it could supply a test unit. Suurmond developed a test unit from scratch, supplying a user-friendly suurDOS® system that can run in three modes: manual, semi-automatic or fully-automatic.
Test unit to investigate the stability of the resin component in adhesives.
Industrial labelling adhesives are applied across an extremely diverse range, ranging from the aerospace industry to the labels on food products.
Avery Dennison uses many different types of adhesives in its products, and the company needed to investigate the stability of the resin component in these adhesives. To support this specific research, the engineers at Suurmond developed a suurDOS® SINGLE installation to handle a single fluid. The purpose of the installation is solely to continuously circulate the resin, and dose samples onto paper for analysis of the final result.
Although Suurmond normally applies its own proprietary gear pumps, this time the order required two pumps from a different manufacturer. This is because the optimized resin product will ultimately be used in existing installations worldwide, incorporating these specific pumps. For the test situation to actually represent production conditions, it was therefore essential to use the exact same pumps. No problem for Suurmond.
The two pumps are installed in series, one for dosing, and the other as a charge pump for the dosing pump. Next to the pumps is the double-walled resin tank, which Suurmond has equipped with a smart assembly including an extra valve to prevent dry-running of the pumps.
To emulate the production environment as closely as possible, the system is further equipped with a pressure control valve combined with two different filters. Quick couplings are used to simplify the exchange of filters. These couplings are of the dry-break type to avoid unnecessary product losses during filter exchange. This results in greater efficiency, ease of use, and a clean work environment.
The processes in the standalone unit are controlled using a PLC with a Siemens HMI. This enables the user to choose from three settings: manual, semi-automatic and fully automatic operation.
Suurmond installed and commissioned the unit following delivery to the customer’s site.
