JumboFlex melters feature a modular design and are available in different variants as premelter, melter, or buffer, depending on the area of application. This makes them suitable for applications ranging from simple pot filling to direct adhesive application via nozzles, to the buffer function as adhesive storage for applications with particularly high adhesive consumption and increased speeds. In addition, two different reservoir sizes of 50 dm3 or 100 dm3 are available. The device cover comes in the same dimensions for all variants, facilitating planning and integration. The JumboFlex can be used in a variety of applications and industries, wherever EVA, PSA, or APAO/PO hot melt adhesives are processed.

JumboFlex advantages – at a glance

  • Increased melting performance thanks to innovative melting grille concept with geometrical alignment of the melting grille elements
  • Adhesive forms from granulate and cushion form to chips, to adhesive blocks of up to 7.5 kg can be processed optimally
  • Designed for adhesive viscosities of up to 65,000 mPas with maximum melting performance and for high-viscosity adhesives up to 100,000 mPas with adjusted melting performance
  • Clean and uniform adhesive application from beginning to end thanks to fast, dynamic adhesive pressure control
  • Easy system integration via standardized fieldbus protocols and Ethernet
  • JumboFlex melter/buffer with optional pattern control and monitoring
  • Simple and efficient maintenance thanks to fine filter and FEP-coated tank

Optimum melting of different forms of adhesive

The distinguishing feature of the JumboFlex is its innovative and unique melting grille concept. It enables a geometrical alignment of the melting grille elements to adjust to the respective form of adhesive (granulate, cushions, or blocks). The flexible alignment optimizes adhesive processing and achieves increased melting performance. A specially developed melting grille is also available for high melting performance with PPE blocks or cushions. The JumboFlex melters are designed for adhesive viscosities up to 65,000 mPas and can process high-viscosity adhesives with up to 100,000 mPas, once the melting performance is adjusted. When using adhesive granulate, the tank can also be filled using an automatic granulate conveyor (RobaFeed). Automatic filling improves efficiency, increases workplace safety, and prevents adhesive contamination.

USER-FRIENDLY OPERATION AND EASY SYSTEM INTEGRATION

The JumboFlex melter comes with a Smart Terminal, which enables the operating and status information to be seen at a glance. The status display shows the current operating status through colored LEDs. In the event of a malfunction, a status code is displayed on the 7-segment display, making it easier to detect any faults. The four practical function keys allow basic functions such as: Switching the WLAN, timer, temperature reduction and pump on and off. For easy operation, an optional touch display with intuitive user interface is available.

Smart Terminal and optional touch display 

The Robatech Control System (RCS) features open interfaces and is compatible with various standardized fieldbus protocols and Ethernet for easy system integration. The adhesive application process can be configured, controlled, and operated conveniently via the standardized Robatech user interface, which is accessible via WLAN, the touch display, or the host system. JumboFlex has already preinstalled all system components and the range of functions related to the adhesive application process can be expanded at any time via software keys. 

SIMPLE AND EFFICIENT MAINTENANCE

Depending on the adhesive viscosity and industrial application, fine filters are used for the JumboFlex melter and buffer variants. These capture dirt before it enters the adhesive applicator, preventing nozzle blockages and system interruptions. The tank features an FEP coating for easy and efficient cleaning. Thanks to its favorable non-stick properties and high temperature resistance, the coating protects all components. A well-cleaned appliance extends the service life and prevents costly operating malfunctions.

WIDE RANGE OF APPLICATIONS

JumboFlex melters are suitable for a wide variety of applications and industries: 

  • Pot filling: e.g. book spine gluing or roller application 
  • Manual adhesive application: Bead and dot application, e.g. for mattress production 
  • Coating applications: full-surface coatings for lamination
  • eCommerce packaging: applying silicone release liners
