Abstract: 1,263,282. Packaging machines. KAMAN AEROSPACE CORP. 14 Feb., 1969 [14 Feb., 1968], No. 8252/69. Heading B8C. An apparatus for placing articles, e.g. candies, in individual receptacles, e.g. paper cups, and for transferring groups of such filled receptacles on to upwardly open receivers such as boxes or trays, comprises a first conveyer 20 feeding a number of boxes 22 in step-by-step fashion along a horizontal path, a second conveyer 40 alongside the first for feeding cups step-by-step along a second horizontal path, the conveyers being arranged to convey the cups and boxes in timed relationship, means for placing the cups in predetermined locations on the conveyer 40, means for loading articles into certain cups on that conveyer and means for transporting groups of such filled cups into the boxes on the conveyer 20. Each conveyer is a walking beam type with spaced pushers therealong associated with a fixed framework below which the beam oscillates.whereby the boxes and cups are supported on the frameworks and the pushers convey the articles intermittently in the direction of the arrow 24 along the frameworks. The conveyer drive is arranged so that the beams operate 180 degrees out of phase, i.e. both their horizontal and vertical movements are 180 degrees out of phase. The cups on the conveyer 40 are fed with candies by means 96, 96 connected to a vacuum source which transfer candies from shoots 34 supplied from vibratory feeder bowls 30. As described six candies are fed at a time into separate cups, and on reaching the downstream end of the conveyer 40 the filled cups are compacted into a distinct group and that group transferred by means 44 connected to a vacuum source to a stationary box on conveyer 20. The cups are fed on to the conveyer 40 from dispensing means 42 at each side of the conveyer. Each means deposits two cups c in an upright position on to the fixed framework of the conveyer from a pair of magazines 210 located side-by-side and in which the cups are held in an inverted position. Withdrawal of the cups is in timed relationship with the movement of the conveyer, and the mechanism includes fingers 228, Fig. 6, with spring-loaded pivoted ends which are inserted into the magazines to engage the lowermost cup and draw it past a pair of cup supporting studs and transfer it in an upright position to a shoot down which it passes to the conveyer framework. Each pair of fingers is carried on a crank arm 230 mounted on a driven eccentric unit 238 mounted on a shaft driven by means associated with the conveyer drive. The compacting means at the downstream end of the conveyer 40 includes a pusher tab 300, Fig. 10, which forces three filled cups on to a deadplate 302 and against a stop 304 pivoted at 306 and driven by cam means 310, 312 to move into and away from a stop position in timed relation to the conveyer movement. Opposed side pressure plates 314 are moved transversely by cam means to compress the filled receptacles. As the beam of conveyer 40 is lowered the cups are retained by a gate 318 pivoted at 320 and driven by cam means 328, 326 to move in timed relationship with the stop 304. Any articles not transferred by the unit 44 are swept from the deadplate 302 by a sweeper tab secured to the downstream end of the conveyer beam, the deadplate being suitably slotted to receive it during its sweeping motion.
