Abstract:
1. A remote, hot melt adhesive metering station, comprising: an axially oriented drive gear manifold having a longitudinal extent extending along a longitudinal axis, an end wall, a top wall, and a side wall; a multitude of manifold pump drive gears rotatably disposed internally within said axially oriented drive gear manifold so as to be disposed at predetermined axially spaced positions within said axially oriented drive gear manifold along said longitudinal axis; a hot melt adhesive inlet supply port defined within said end wall of said drive gear manifold for supplying pressurized hot melt adhesive to said multitude of manifold pump drive gears; a multitude of rotary, gear-type metering pump assemblies mounted upon said top wall of said drive gear manifold, at predetermined axially spaced positions along said top wall of said drive gear manifold, wherein each one of said rotary, gear-type metering pump assemblies comprises a pump driven gear having a peripheral portion thereof extending radially downwardly out from its rotary, gear-type metering pump assembly so as to be respectively disposed in enmeshed engagement with one of said multitude of manifold pump drive gears rotatably disposed within said drive gear manifold such that each one of said rotary, gear-type metering pump assemblies outputs a precisely metered amount of hot melt adhesive material; a multitude of outlet port hose connections, to which conveyance hoses can respectively be operatively connected, mounted upon said top wall of said drive gear manifold of said metering station, at predetermined axially spaced positions along said side wall of said drive gear manifold, for permitting said precisely metered amounts of the hot melt adhesive material, respectively supplied directly to said multitude of outlet port hose connections by said multitude of rotary, gear-type metering pump assemblies of said metering station, to be dispensed by said metering station toward remote hot melt adhesive applicators by the conveyance hoses which are respectively operatively connected to said multitude of outlet port hose connections of said metering station; and a multitude of fluid flow paths defined within said multitude of rotary, gear-type metering pump assemblies mounted upon said top wall of said drive gear manifold, and within said drive gear manifold for respectively fluidically connecting said outputs of said multitude of rotary, gear-type metering pump assemblies to said multitude of outlet port hose connections.
