NORDSON CORP.: Retrofit System

April 21, 2010

Nordson Corp. has announced the introduction of 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.

The Fulfill system replaces manual melter monitoring and refilling with an automatic, controlled process, decreasing production staff’s exposure to hot surfaces, molten adhesive, and repetitive lifting of adhesive.

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 on-site installation.
