Abstract
An apparatus such as a glue gun system that utilizes solid beads of meltable material such as glue. The glue gun has a housing that contains a pervious barrier. The pervious diaphragm separates the beads from an airstream that is used to deliver the beads from a hopper to the housing. A load level control detects varying levels of the beads in the housing. A motor in the interior of the housing drives a feed screw. The feed screw forces the beads towards a nose assembly on the forward end of the housing. A heating element is provided in the nose assembly. A co-axial hose delivers the beads from a hopper to the housing through an interior passage. An exterior annulus of the hose delivers the separated airstream away from the housing. Electronics control the rotation of the feed screw and controls the power to the heating element. A hopper contains beads of the meltable material. An electric metering device is located in the hopper for regulating the amount of beads placed into the airstream within the interior passage of the co-axial hose.
