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 pneumatic 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.
VELA mounts a tank that distributes heat more evenly achieving a precise and effective melting while increasing energy savings. The wide loading mouth open on 3 sides facilitates filling by making it easier to clean and maintain. The 20° angle of inclination and fan-arranged melting fins are designed to improve the melting of glue that slides toward the pump suction point. The angle of inclination of the tank bottom (approx. 20°), the fan-shaped melting fins positioned parallel to the upper edge of the tank have been specially designed to improve the melting of the glue, which slides directly towards the pump suction point. The quick discharge, on the other hand, positioned at a lower level and on the opposite side to the suction point, facilitates the collection of any adhesive impurities or carbonised glue residues by conveying them into a single sump and preventing them from causing machine downtime if sucked in by the pump.
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 new reversing system with the solenoid valve mounted directly on the pump, in addition to increasing the reversing speed, guarantees absolute cycle precision by ensuring that the flow rate of the adhesive is always constant and balanced and significantly reducing pressure surges.
The use of reed-switch type proximity sensors (protected and sealed inside the electronic cylinder, and therefore never in contact with the outside environment and not subject to wear) increases the reliability of life cycles, reducing machine shut-downs for malfunctions or maintenance, giving the system mechanical solidity, in addition to resistance to environmental conditions and to electrical and electromagnetic disturbances.
The 14:1 dual-effect piston pump is ideal for melting and applying adhesives and thermoplastic materials with a viscosity of up to 30,000 Cps. Fully manufactured by Preo, the pump is treated with a hard oxide coating and it is easy to extract in case of maintenance or replacement operations. The bottom of the pump is inspectable in order to check the conditions of the suction sphere.
An automatic pressure relief valve is installed as standard to ensure maximum safety during operation by automatically discharging residual pressure in both emergency and system shutdown.
