Abstract: 1322784 Attaching nozzles to containers KRAFTCO CORP 3 Sept 1970 [26 Sept 1969] 42149/70 Heading B8C In an apparatus for attaching dispensing nozzles 19, 20, Fig. 4, to generally cylindrical packages 13 a procession of the latter are fed forward by a conveyer 21 on to a table 45 and toward a nozzle-attaching station 25 and a pair of flippers 47, 47 are periodically raised in slots 44, 44, from below the upper face of the table 45, to transfer each package, in turn, beneath a pair of laterally-spaced endless belts 29, which roll the package along the table 45 and in rolling contact with a pair of raised stops 51, 51 for aligning the package with its axis transverse to the feed line direction. A label 23, with a nozzle 19 located in the aperture 27 therein, is placed, with its pressure-sensitive adhesive face upward, on a suction table 61 at the nozzleattaching station 25 by a mechanism which is triggered by the preceding package as a second set of laterally-spaced endless belts 77, 77 roll it past a first photo-electric cell 71 adjacent the discharge side of the station 25. When the preceding package passes a second photo-electric cell 57 the stops 51, 51 are lowered so that the package, located at this position, is rolled forward along the table 45 by the belts 29 and over the label strip 23 which is stuck on to the package with the flange 67 of the nozzle 19 enclosed between the strip 23 and the package wall. As the package, with the nozzle, is rolled by the second pair of belts 77, 77, along a pair of laterally-spaced rails 68, 68 and approaches the cell 71 a take-up roll 123 pulls the next strip 23 of a plurality of strips on a carrier web 112 upwardly and over the sharp corner 113 of a stripping plate 115 to peel the strip 23 as it is urged into position, with its adhesive face upwards, on the suction plate 61 by air jets from nozzles 119. A feed reel 121 feeds several strip lengths of the web at a time whenever a fed loop of the web around a tensioning roller 122 becomes sufficiently shallow. When the second cell 57 senses the package a plunger 107 is moved downwardly by a pneumatic cylinder 110 so that a nozzle 19, previously placed at the end of a pair of support channels 101 by a reciprocatable pawl 203, is stripped from the supports 101 and is inserted into the aperture 27 in the label 23 on the plate 61. On the return stroke of the plunger 167 the feed pawl 103 moves forward to place the next nozzle 19 below the plunger and is then returned to rest on top of the next nozzle to be fed. The package is discharged at the end of the belts 77 which have foamed rubber active surfaces. A vibrating hopper 87, described in detail with respect to, Fig. 6, not shown, feeds the nozzles with their caps downward, to the support channels 101. When the cap 20, Fig. 3, is removed from the nozzle a sharp knife may be inserted through the discharge orifice to puncture the package wall. The input conveyer 21 operates continuously as do the first and second sets of belts 29 and 57, the strips 23 and nozzles 19 being operated intermittently.
