Concept Stream: high tech glue melting

An innovative melting process, quick heat-up and greater operator safety: with
its new Concept Stream, Robatech further enhances the gluing process.

Concept Stream is a tankless Robatech melting and dispensing system for granulated thermoplastic adhesives. Depending on the amount of glue needed, the melter - which is designed for on-demand production - offers numerous possible uses in various industrial applications. This energy efficient and safe gluing system is based on the tested Concept 5 melter with GreenLine technology.
High performance with less bulk. The heart of Concept Stream is its compact, high performance tank, designed to ensure maximum melting yield (8kg/h). With melt-on-demand technology it is possible to choose the intensity and amount of melting according to need. Moreover, the controlled flow reduces the risk of explosion and the amount of residue in the tank considerably and prevents most nozzle blockage. It also increases the adhesive filters life span, with resulting lowered operational costs.

Fast and efficient processes. The system takes just 16 minutes to heat up to 160 °C, and the standby function guarantees quick startup when needed. Fill level supervision with run empty protection prevents glue from being dosed and stops the system, avoiding problems arising from improperly glued or unglued products. Concept Stream (which is part of the GreenLine range) has also been made to be highly energy efficient: CoolTouch insulation of the tank, pump and dispenser saves over 20% on energy compared to Standard Concept.

Increased operator safety. On the standard version, the melter is filled manually. The filling area is separated from the hot part by a CoolTouch adapter to guarantee safe manual filling. In order to further increase safety standards, the melter can be configured for optional automatic filling (this can also be done at a later stage with the RobaFeed granulate feed system). The integrated CoolTouch insulation enhances protection of the operator by considerably reducing the risk of burns. Automatic pressure release prevents the system from accruing too much pressure.

Modular and simple. With a modular structure featuring up to eight attachments for hoses, heads and the RobaVis Touch operator panel, the new Concept Stream melter is easy to integrate with existing lines, making possible a flexible gluing process. The fact that it is equally suitable for high and low adhesive consumption applications makes it suitable for a wide array of processes in different sectors.
