At IDEA last week, Nordson Corporation introduced its new Fulfill retrofit system, which allows owners of Nordson ProBlue 4,7 and 10 liter melters to add maintenance- and labor-saving automatic adhesive filling capability to their existing operations. Automatic filling maintains optimal hot melt adhesive levels to increase uptime and consistency while decreasing waste, to advance sustainability.
As adhesive is dispensed, levels in the melter tank decrease. When a “low” level is reached, a sensor transmits a signal to a vacuum wand, which conveys adhesive pellets, pastilles or mini-slats directly to the melter tank. By automatically adding small quantities of adhesive at needed intervals, the system keeps the tank from running dry, minimizing missed beads and package rejects. A constant adhesive level also reduces variations in adhesive temperatures, resulting in better bonding.
The system is closed to ambient air, preventing adhesive contamination by dirt, dust or other debris.
Standard Fulfill retrofit system features include a vibrating vacuum wand to help prevent adhesive from sticking in the tote container, an external control box with membrane panel, a fill/fault indicator, and a disposable filter, for easy maintenance.
Factory pre-assembled and pre-calibrated components allow simple, fast, on-site installation.
Nordson ProBlue melters are used in end-of-line packaging of disposable hygiene products.Fulfill retrofit systems for use with Nordson VersaBlue melters used in disposable hygiene products manufacturing will be also available in 2010.
Nordson Corporation also introduced the Universal TruFlow Adhesive System, a new hot melt adhesive applicator, flow-monitoring and control package that minimizes ramp-up time and variance in adhesive volume while reducing product rejects and downtime.
High-speed, disposable-hygiene product manufacturing operations that dispense adhesive intermittently or continuously using spray- or slot-applicators can increase process control, reduce adhesive waste and improve product consistency.
