    Abstract: An adhesive dispensing device includes a heater unit for melting adhesive material, a receiving space for feeding the heater unit, and a cyclonic separator unit for delivering adhesive pellets to the receiving space. The cyclonic separator unit includes a tangential inlet pipe proximate to a top end of a generally cylindrical pipe, which is connected to the receiving space at an open bottom end. The tangential or spiral flow of air and adhesive pellets generated through the cyclonic separator unit reduces the speed of the air and adhesive pellets to avoid splashing of molten adhesive material while maintaining enough speed to avoid adhesive build up on the generally cylindrical pipe.

    Abstract: An adhesive dispensing device includes a heater unit for melting adhesive, a fill system communicating with a receiving space for feeding the heater unit, and a reservoir for receiving melted adhesive from the heater unit. The dispensing device also includes a capacitive level sensor located along a sidewall of the receiving space such that the level of adhesive in the receiving space can be detected by sensing the difference in dielectric capacitance where the adhesive is located compared to where air acts as the dielectric. The size of the driven electrode produces a broader sensing window capable of generating multiple control signals corresponding to different fill levels of adhesive. The receiving space and reservoir are minimized in size so that adhesive is not held at elevated temperatures long enough to char or degrade.

    Abstract: Systems, feeder devices and methods for moving particulate hot melt adhesive from an adhesive supply to an adhesive melter. A feeder device includes a body having an inlet and an outlet, and an interior communicating with the inlet and the outlet. The inlet is configured to receive particulate hot melt adhesive from an outlet of the adhesive supply, and the outlet is configured to provide particulate hot melt adhesive to an inlet of the adhesive melter. The feeder device further includes a mechanical agitator positioned in the interior for urging the particulate hot melt adhesive in a flow direction toward the outlet.

    Abstract: An adhesive melter and a method for operating the melter enables predictive maintenance of an exhaust air filter used to remove pressurized air flow that delivers solid adhesive particulate from a fill system into the melter. To this end, the fill system repeatedly actuates to refill a receiving space, and a controller monitors a duration of each fill system cycle. When changes in a calculated average duration of a plurality of fill system cycles exceed a maintenance threshold, an alert is emitted at a user interface to prompt maintenance or replacement of the exhaust air filter before a complete shutdown of the fill system is caused by clogging of the exhaust air filter. Consequently, unplanned downtimes caused by clogged exhaust air filters in the adhesive melter can be minimized, regardless of any variable conditions occurring at the melter.
