Abstract

Four pineapples are contour peeled simultaneously fed from a single file elevator conveyor feed system. To accomplish this, the pineapples are picked up from the elevator conveyor, spaced in groups of four and dropped through sliding trap door onto chutes in a group former. The four pineapples are picked up by the pusher fingers of four parallel feeder conveyors and advanced through centering heads. The feeder conveyors then force the four pineapples onto core pins of four core turrets having oppositely projecting core pins. The core turrets index 180* and shift axially to present the cored pineapples to four peeling turrets on the same axis. The coring is completed on the core turrets after which the cored pineapples are transferred to peeling pins on the core turrets and the crowns of the pineapples are cut off. Each of the four peeling turrets has four peeling pins spaced at 90*. The peeling turrets index in 90* steps and bring pineapples beneath peeling heads above the turrets. The pineapples are pushed through the peeling heads from below for contour peeling after which the pineapples are carried across butt end trimmers for disposition by slicing or other processing stations.
