Abstract

This invention provides a multi-outlet adapter for conversion of at least one source of pressure or vacuum to a multiplicity of outlets of the source(s). The adapter comprises at least two abutting blocks. The pressure and/or vacuum sources are connected to aperture(s) in a surface of the first of the blocks. These aperture(s) terminate in first depression(s) in the opposite face of the first block. The depression(s) in the first block communicate directly with a multiplicity of apertures in the abutting face of the second block which apertures in turn terminate on the opposing face of the second block in a multiplicity of second depressions which constitute the pressure or vacuum outlets. The adapter has particular application in self-adhesive label applicators in which a third block preferably abuts the second block and comprises a grid formed from a multiplicity of apertures which each communicate with the second depression(s). The grid of apertures thus resolves the outlets into greater detail. The adapter can be programmed by inserting a template adjacent to any surface of one of the blocks other than the first block so as to occlude and concurrently select certain only outlets.

Dependent claims

A multi-outlet adapter for conversion of one source of pressure and one source of vacuum to two respective sets of outlets each said set having a multiplicity of openings, said adapter comprising three abutting blocks having opposed mating surfaces, said pressure and vacuum sources being connected to one surface of said first block other than the mating surface of said first block, said first block mating surface having a pair of first depressions therein extending substantially in a first direction, each said first depression communicating directly to a connection of a corresponding one of said sources;

one mating surface of said second block having two sets of apertures therein with each set having a plurality of apertures, the apertures of each said set of apertures all communicating with a corresponding one of said first depressions, the other mating surface of said second block having two sets of second depressions therein each of which correspond to, and communicate with, one of said sets of apertures, each set of second depressions having a plurality of said second depressions which each extend in a second direction substantially mis-aligned with said first direction;
and said third block having an array of said openings therethrough at predetermined locations with each communicate the mating surface of said third block with another surface of said third block, at least some of said openings being aligned with said second depressions of one said set of second depressions and the remainder of said openings being aligned with said second depressions of the other set of said second depressions, said some openings constituting one said set of outlets and said remainder of said openings constituting the other said set of outlets.
