Definitions

• thermoplastic material deposition or application procedures In connection with the delivery of hot melt adhesive or other thermoplastic materials for use in implementing various or different hot melt adhesive or other thermoplastic material deposition or application procedures, conventional practices have dictated that depending upon, or as a function of, particular predetermined application requirements or parameters, a particularly or specifically structured system be designed, manufactured, and installed. As can therefore be readily appreciated, when considered from a somewhat opposite or reverse point of view or perspective, and as is well known in the industry, different deposition or application procedures require different structural systems to be designed, manufactured, purchased, and installed. For example, different deposition or application procedures may require differently sized hot melt adhesive or other thermoplastic material supply units or tanks.
• different deposition or application procedures comprising, for example, different output material volume parameters or requirements, may dictate or require the use or employment of different hot melt adhesive or other thermoplastic material metering pump assemblies.
• different deposition or application procedures comprising, for example, the minimalization of pressure losses, or the optimalization of pressure values, occurring within the various fluid flow lines or conduits comprising the entire hot melt adhesive or other thermoplastic delivery system, may dictate or require that the hot melt adhesive or other thermoplastic material metering pump assemblies and their applicators be disposed or located relatively close to the hot melt adhesive or other thermoplastic material supply units or tanks.
• FIGURE 4a is a cross-sectional view of the distribution manifold as illustrated within FIGURE 4 and as taken along lines 4a-4a of FIGURE 4;
• the front wall member 118 of the modular metering assembly 104 is provided, for example, with sixteen fluid supply outlet ports 120, wherein the sixteen fluid supply outlet ports 120 are arranged in four sets or arrays, with each set or array of the fluid supply outlet ports 120 comprising four individual fluid supply outlet ports 120.
• the modular tank assembly 102 has disposed therein a hot melt adhesive or other thermoplastic material reservoir or hopper 126 within which a supply of the hot melt adhesive or other thermoplastic material is melted and maintained at a predeterminedly desired temperature level and viscosity.
• the primary pump 106 receives the hot melt adhesive or other thermoplastic material from the hot melt adhesive or other thermoplastic material reservoir or hopper 126, pressurizes the material to a predetermined pressure value, and conveys the same toward the modular metering assembly 104 through means of the fluid supply conduit 112.
• the modular metering assembly 104 has a distribution manifold 128 disposed internally thereof, and the distribution manifold 128 has a plurality of metering stations, such as, for example, four metering stations 130, 132,134,136, fixedly mounted thereon and operatively or fluidically connected thereto.
• a plurality of mounting brackets 138,140,142,144 are fixedly secured internally within the modular metering assembly 104, and that the plurality of metering stations 130,132,134,136 are adapted to be respectfully mounted and fixedly secured thereon.
• each one of the plurality of metering stations is also seen that each one of the plurality of metering stations
• a first vertically oriented fluid return passageway 244 extends downwardly within the distribution manifold 128 from a first one of the metering interfaces 170,172 disposed upon the upper or top wall member 194 of the distribution manifold 128, and a first horizontal, longitudinally oriented fluid return passageway 246 extends inwardly within the distribution manifold 128 from a first one of the metering interfaces 174,176 disposed upon the front wall member 196 of the distribution manifold.
• a third horizontally oriented fluid return passageway 252 is provided for fluidically connecting the second one of the metering interfaces 174,176 to the second horizontally oriented fluid return passageway 248 and the fluid outlet port 242, and in this manner, return hot melt adhesive or other thermoplastic material is able to be returned to the hot melt adhesive or other thermoplastic material reservoir or hopper, from the metering stations 130,132, 134,136, along the fluid return paths 186,188,190,192, the distribution manifold 128, and the fluid return conduit 114.
• a pair of oppositely disposed check valves are respectively incorporated within the distribution manifold 128 and the fluid supply and fluid return conduits 112, 114, at the junctions of such components, as illustrated at 258,260 in FIGURES 4c and 4b, although it is noted that only the check valves incorporated within the distribution manifold 128 are illustrated.
• the various structural components are able to be separated from each other without any inadvertent discharge or leakage of the hot melt adhesive or other thermoplastic material across the noted interfaces.
• the clamping members 298,298 are then rotated or pivoted around the adjustment or tightening screws 296,296 through means of an angular extent of 180°, and subsequently, the adjustment or tightening screws 296,296 are tightened so as to cause the projecting lug portions of the clamping members 298,298 to respectively tightly engage the clamping brackets 294 thereby causing the lower collector housing portion 279 of the reservoir or hopper 226 and the distribution manifold 228 to be tightly engaged with each other.
• FIGURE 9 a fourth embodiment of a new and improved modular system for the delivery of hot melt adhesive or other thermoplastic materials, constructed in accordance with the principles and teachings of the present invention, and similar to the first embodiment modular system 100 as disclosed within FIGURES 1 and 3, except as will be noted hereinafter, is disclosed and is generally indicated by the reference character 400. It is to be appreciated that in view of the fact that this fourth embodiment modular system 400 is similar to the first embodiment modular system 100 as disclosed within FIGURES 1 and 3, a detailed discussion of the fourth embodiment modular system 400 will be omitted for brevity purposes, the disclosure and description of the same being confined substantially to the differences between the fourth and first embodiment modular systems 400,100.
• a plurality of applicator hoses 422 can be respectively fluidically connected to the plurality of fluid supply outlet ports 420 for conducting the hot melt adhesive or other thermoplastic material to applicator heads or the like.
• the fluid supply outlet ports which would normally be defined within the front wall member 418 of the modular metering assembly 404 as a result of being respectfully fluidically connected to and associated with the metering gear pump outputs of the metering station 434, are not in fact defined or provided within the front wall member 418 of the modular metering assembly 404, but, to the contrary, the hot melt adhesive or other thermoplastic material will be routed internally within the distribution manifold disposed within the modular metering assembly 404 and outputted to the externally and remotely located metering station 434 from an outlet supply port 421 defined within the front wall member 418 of the modular metering assembly 404 and conducted along a hot melt
