ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to hot melt adhesive applicators, and more particularly to a hot melt adhesive applicator assembly which enables the various components of the applicator assembly to be operatively assembled in various different modes or orientations so as to provide increased versatility for the hot melt adhesive applicator assembly with respect to the installation, integration, incorporation, and accommodation of the same into existing hot melt adhesive application or dispensing production equipment, installations, or production lines.
BACKGROUND OF THE INVENTION
In connection with hot melt adhesive applicator assemblies, such assemblies are conventionally provided in connection with various hot melt adhesive application or dispensing production equipment, installations, or production lines. However, due to the diversity of the disposition or arrangement of the various components comprising such various hot melt adhesive application or dispensing production equipment, installations, or production lines, it has conventionally proven difficult to enable such hot melt adhesive applicator assemblies to be readily installed, integrated, incorporated, or accommodated within such diverse equipment, installations, or production lines without the use of auxiliary adaptors.
It is also necessary to render such hot melt adhesive applicator assemblies relatively compact in order to satisfy the aforenoted spatial requirements of the various hot melt adhesive application or dispensing production equipment, installations, or production lines. Still further, a critical component of such hot melt adhesive applicator assemblies is the adhesive material filter which of course must be changed periodically so as to ensure the cleanliness or purity of the adhesive to be supplied to the hot melt adhesive applicator modules. The disposition of the filter component within the hot melt adhesive applicator assembly must therefore also be taken into consideration in order to render the replacement or exchange of the filter assemblies or modules quick and easy without any interference with or obstruction by either other existing components of the hot melt adhesive applicator assemblies, or existing components of the various hot melt adhesive application or dispensing production equipment, installations, or production lines.
A need therefore exists in the art for a new and improved hot melt adhesive applicator assembly which will permit the same to be used in connection with various hot melt adhesive application or dispensing production equipment, installations, or production lines, which is relatively compact, and which facilitates the ready and quick exchange or replacement of the filter assemblies or modules as a result of the elimination of any interference or obstruction of the filter assemblies or modules either with other components of the hot melt adhesive applicator assemblies, or existing components of the various hot melt adhesive application or dispensing production equipment, installations, or production lines.
OBJECTS OF THE INVENTION
Accordingly, it is an object of the present invention to provide a new and improved hot melt adhesive applicator assembly.
Another object of the present invention is to provide a new and improved hot melt adhesive applicator assembly which overcomes the various disadvantages of PRIOR ART hot melt adhesive applicator assemblies.
An additional object of the present invention is to provide a new and improved hot melt adhesive applicator assembly which has structural provisions incorporated therein which readily permits the same and its various components to be disposed in different orientations so as to permit the applicator assembly to be readily installed, integrated, incorporated, and accommodated within existing hot melt adhesive application or dispensing installations, equipment, or production lines.
A further object of the present invention is to provide a new and improved hot melt adhesive applicator assembly which is compact and readily facilitates the replacement or exchange of the filter assembly due to the disposition or location of the same within the assembly whereby any interference by or obstruction with either other components of the assembly or existing components of the various hot melt adhesive application or dispensing production equipment, installations, or production lines, is effectively eliminated.
SUMMARY OF THE INVENTION
The foregoing and other objectives are achieved in accordance with the principles and teachings of the present invention through the provision of a new and improved hot melt adhesive applicator assembly which comprises a hot melt adhesive applicator head which is provided with an upper or top surface portion and a back or rear surface portion upon which connectors are respectively provided so as to selectively connect an adhesive supply hose thereto. Provisions are likewise made for selectively mounting support brackets upon such upper or rear surface portions of the applicator head, and a filter assembly is adapted to be removably mounted upon an angled or inclined surface portion of the applicator head such that the filter assembly is disposed at a position intermediate the two alternative adhesive hose connectors. Still further, the entire applicator head may be angularly rotated through an angular movement of 90° and yet the filter assembly will be disposed upon its angled or inclined mount such that the filter member will nevertheless be oriented substantially vertically whereby adhesive will not undergo inadvertent leakage out of the filter assembly during filter change operations.
