The new VELA melters represent a major step forward in the application of hot-melt thermoplastic adhesives in a variety of sectors, offering a range of advanced features specifically designed to improve production flexibility and versatility of operations, making them the ultimate choice for all companies seeking cutting-edge gluing solutions.
The VELA Series applicators for hot-melt adhesives with gear pump are significantly innovative in terms of simplicity of use, productive flexibility, maintenance operations and costs, speed of installation, easy programming, high safety standards, exceptional reliability and total integration with any existing assembly line.
The VELA systems are equipped with a new microprocessor with 7" LCD Touch Screen colour display, through which, with a single graphic interface showing all sections of the system (tank, manifold, hoses and guns).
The operator is supported in everyday activities like managing and setting temperatures, pump control, setting machine parameters and glue sections, and integration and communication with any external units, allowing for immediate use of the system even by non-specialized personnel, without any problems involving codes or foreign languages to be interpreted.
The particularly well-finished design makes the system appreciable even in aesthetic terms.
Modern and distinctive design combined with modularity, sustainability, compatibility, advanced interconnectivity, and increased energy efficiency provide the ideal quality solution for adhesive application in multiple sectors.
Every part of the applicator can be inspected easily by opening the practical body system.
VELA Applicators - customizable in several configurations and capable of satisfying all gluing needs - allow the operator to work in complete safety and to significantly optimize application times without wasting time uselessly.
VELA melters, which can be customized in different configurations according to each Customer's specific needs, allow operators to work in total safety and significantly optimize application times. All parts are easily inspected thanks to a practical, safe and quick-to-open cover system that significantly reduces downtime and maintenance.
VELA has been conceived and designed to integrate easily with a wide range of companies' existing equipment so that production lines can be upgraded without costly replacements or radical changes. Its total compatibility with other existing systems, easy installation through plug & play connections and interchangeability of modules make VELA the perfect system for every need.
VELA is equipped with special insulation that significantly improves the insulation system keeping the internal temperature constant. This improvement ensures even heat distribution and increases the energy efficiency of the entire system, reducing the heating time and, consequently, the energy consumption itself.
The main functions of the user interface can be summarized as follows: sequential channel heating, machine ready signal and pump start, absolute maximum temperature protection system, dual mode economy, clock, weekly programming with “daily ECO” function, color status bar with machine status in real time, disable thermoregulation hose/gun pair, management of up to 8 independent channels with integrated glue pattern programming, hours-life, hours-work, pump cycles counters, customization of system section names and glue programs, copy/paste parameters function, user management with password, firmware upgrade via USB port, upload, download and saving of machine parameters and configurations, scheduled programmed maintenance, event log and real-time diagnostics.
In line with Industry 4.0 principles, VELA has a simple, intuitive yet advanced interface that facilitates integration with OEM systems. Through PLC Interface and Modbus TCP-IP protocol, the melter is able to communicate and dialogue with other devices and management systems, enabling real-time remote monitoring and control.
The new tank was entirely redesigned to ensure perfect efficiency in terms of melting evenness and capacity. The large loading inlet open on 3 sides makes filling easier, optimizing cleaning and maintenance operations. The heaters are positioned on the bottom of the tank and across the melting fins, and are specifically designed to create a special grid to improve the melting of the glue more efficiently, so it can slide directly towards the pump drawing spot. This heating system allows a homogeneous and uniform distribution of the heat improving the thermal efficiency of the whole system with a consequent energy saving. The rapid discharge facilitates the collection of any impurities in the adhesive or burnt glue residue, conveying them to a single sump and preventing them from being sucked up by the pump and causing a machine shutdown, also allowing for quick cleaning operations either for maintenance purposes or to replace the adhesive.
Each melter is supplied as standard with an easy-to-access and easy-to-replace glue filter located at the top of the manifold that prevents impurities in the adhesive from clogging hoses, guns and nozzles. A wide range of models is available (with single or multilayer micro filter mesh and different pitches from 200 microns and up) depending on the type of adhesive used.
The melters are fitted with variable speed AC motors controlled by an inverter to obtain reduced overall dimensions and easy access both for inspection and maintenance, thanks to a quick connector.
Gear pumps of different capacities (0.8 – 3.0 – 7.0 - 10 and 20 cc/rev) are available with the same dimensions.
These pumps are absolute precise and reliable, made of fully hardened super-quick steel. Like all internal parts of the melter, even the pump is easy to inspect and remove in case of maintenance or replacement.
VELA melters are supplied as standard with a valve (pneumatic or mechanical) to keep the set pressure constant and to ensure safety while using the system, discharging the adhesive pressure into the system automatically even in an emergency.
Optionally, it is possible to mount a sophisticated control system that shows the adhesive output pressure on the applicator display. This view can be combined with a traditional digital pressure gauge that shows the pressure of the adhesive in bars.
