Title: Improvements relating to the handling of lightweight containers
IPC: B65G47/14
Filed: 1961-06-27
Abstract: 982,653. Endless conveyers; orientating articles. ILLINOIS TOOL WORKS Inc. June 27, 1961 [June 27, 1960], No. 23310/61. Headings B8A and B8S. In producing a batch of thin wall plastic cups 64 with their openings all facing in the same direction, the cups are passed from an endless conveyer elevator 22 into a separating area 36 which includes a pair of rotatable separators 42 for directing the cups into three troughs 44. At the entrance to each trough a jet of air from means 124 precludes the formation of a dead space or pocket. A polyethylene shroud 58 which overlies the area 36 and the inlet ends of the troughs has its downstream end provided with flexible strips 62. Cups which are bottom down when they leave the separators drop into the throats 46 of the troughs and are carried along by first and second pairs of belts 48, 50 to funnels 52 of discharge stations which are connected by pneumatic conveyer tubes 54 to a machine 56 for rolling the rims of the cups. Cups which are not bottom down as they arrive on the troughs 44 are blown upwards by air under pressure from apertures 98 provided in the area of the shroud 58 in manifolds 89. Most of these cups fall back bottom first and are conveyed by the belts right side up. Cups which land on top of other cups or in telescoped nested relation, more than three cups high, are blown back upstream by air from nozzles 126. Some cups fall within the troughs in sufficiently upright position to be carried away upright by the belts but the others pass back into the shroud where they are properly orientated. Minimum spacing between the cups is provided by a spreading finger 130 which tips as each cup engages it, causing the cup to bump any immediately trailing cup back upstream a slight distance. At the discharge station funnels 52, the cups are tipped upside down by a flipper 140 and by suction before passing into the tubes 54. The cups may be made to rotate in the tubes 54 by imparting a swirling motion to the air in the tubes. In the event of a jam-up at a discharge station, photo-cell detector apparatus 178 causes air under pressure to be supplied to a bore 174 and the cups are blown out of the funnel area. The cups are then directed back toward the nozzle 126 by a deflector 136 and by the other nozzle 138 ready for orientating. In a modification, Figs. 10, 12, the cups are fed to a distribution chamber 190 by a pneumatic elevator 184, the cups being directed to one or other of a pair of troughs 44b by diagonally disposed jets 192 operated alternately. Wire mesh conduits 194 connect the chamber 190 to the troughs which are covered by wire mesh hoods 196. The cups are stacked in a horizontal tube 198. Specifications 865,024 and 865,025 are referred to.
