Abstract: This invention relates to a system for dispensing thermoplastic materials and particularly to a system for dispensing so-called ''''high performance'''' hot melt adhesives. More specifically, the invention relates to dispensing systems in which solid thermoplastic or hot melt material is melted in small charges or batches and is then supplied upon demand in liquid form to a dispensing gun, the quantity of molten material being maintained at a minimum from the area in which it is melted to the dispensing nozzle of the gun.

Abstract: A fluid operated system of modular guns for dispensing liquids such as molten adhesives. The system includes multiple guns in the form of readily removable cylindrical modules that mount in apertures of a fixed service block or manifold. The service block and guns have passages which register when the system is assembled whereby the guns may be easily removed from the fixed service block and replaced without disconnecting any fluid lines or other service equipment. Each gun module is secured to the service module by a connector located at one end of the gun module so that it is free for relatively unlimited thermal expansion and contraction without damage to either module.

Abstract: A reciprocating ram type of thermoplastic material dispensing system which includes a hopper from which solid material is fed in small batches into a pressure chamber in front of a reciprocating ram. On the forward stroke of the ram, the solid material is forced through a melting chamber and subsequently supplied in molten form to a dispensing gun. The system includes a pressure regulator in the molten material flow stream to maintain an even pressure of the material at the dispensing gun. It also includes a control circuit for cycling the ram in synchronization with insertion and removal of workpieces or products adjacent the nozzle of the gun. An interlock switch is provided in the control circuit to prevent too frequent recycling of the ram and consequent choking of the system.

Abstract: An applicator for melting thermoplastic material and supplying the molten or liquid material under pressure and at a controlled temperature to an applicator head. The material is melted by a heated grid through which it passes to a storage reservoir. From the reservoir it is pumped to a gun type applicator head. The pump is a single piston double-acting pump that is driven by an air motor. The liquid reservoir, the pump, the applicator gun, and the hose connecting the gun to the pump are all heated and maintained at an even temperature so that there are neither hot spots nor cold spots in the system. The applicator incorporates a self-cleaning mechanism for cleaning the grid and the tank by heating the degraded carbonaceous hot melt material to a temperature at which it is decomposed and converted to a powdered ash that is easily removed.
