Abstract
An adhesive liquid dispensing apparatus includes a gun manifold, a dispensing module, and a dispensing orifice. The inlet port of the gun manifold is directly coupled with a reservoir of adhesive hot melt liquid that is fixedly attached to the manifold. The contents of the reservoir are under pressure so that the adhesive hot melt liquid is dispensed from the adhesive liquid dispensing apparatus without the need for heated supply hoses to connect the inlet port of the manifold to a remote source of adhesive hot melt liquid. Preferably, the adhesive liquid dispensing system is coupled with a robot that controls the positioning of the system during an adhesive liquid dispensing operation.
Claims8
A method for operating an adhesive liquid dispensing apparatus having an adhesive liquid reservoir coupled in fluid communication with a dispenser having a dispensing orifice, the method comprising:
- supplying liquid from the reservoir to the dispenser while dispensing the adhesive liquid from the dispenser;
- detecting a reduced adhesive liquid level within the reservoir;
- upon detecting the reduced adhesive liquid level, automatically moving the reservoir and the dispenser to a docking station;
- and
- refilling the reservoir with additional adhesive liquid transferred from the docking station to the reservoir.
