A melter for heating and melting particulate hot melt adhesive into a liquefied form is disclosed. The melter includes a heated receiving device having an interior with an inlet configured to receive the particulate hot melt adhesive and an outlet. A flexible hopper holds a supply of the particulate hot melt adhesive and a particulate hot melt adhesive feed device allows the particulate hot melt adhesive to be directed from the flexible hopper to the inlet of the heated receiving device.

Hot melt adhesive supply and methods associated therewith

A dispenser body having a liquid inlet, a discharge outlet, and a flow channel capable of directing a flow of the hot melt adhesive from the liquid inlet to the discharge outlet. The flow channel includes a valve seat between the liquid inlet and the discharge outlet. The dispensing module further includes a needle having a valve member mounted for movement in the dispenser body between an open position in which the valve member is disengaged with the valve seat allowing liquid flow from the discharge outlet and a closed position in which the valve member is engaged with the valve seat preventing liquid flow from the discharge outlet. A first electromagnetic coil is activated to move the needle to the open position and a second electromagnetic coil is activated to move the needle to the closed position.

Fluid dispenser utilizing dual coils and methods of fluid dispensing

A dispensing system includes a hot melt unit delivering heated adhesive through a hose to at least one dispenser gun, which is actuated by an outside source of gun actuation. Rather than directly connecting the source of gun actuation to the dispenser gun, the source of gun actuation is connected to the hot melt unit and then to the dispenser gun. For example, the gun actuation signals may be terminated at a terminal block in the hot melt unit, which enables the hot melt unit to monitor the gun actuation signals. The dispensing system is operable to perform various diagnostics pertaining to the dispenser gun and the system as a whole based on these monitored gun actuation signals.
