Patent number: 4585126Abstract: A method and apparatus are disclosed for high-speed processing of fruit or the like wherein the fruit is initially accumulated and aligned at a pick-up point for capture in spaced-apart pockets of a singulation conveyor at the pick-up point to maintain the fruit in predetermined linear spacing and to accelerate the fruit to a predetermined processing speed, a processing conveyor being operated at a synchronized speed relative to the singulation conveyor for receiving the individual units of fruit, the fruit being carried in trays past a sensor station after which the fruit is discharged from the trays into one of a plurality of discharge passages according to the individual characteristics of the fruit units. A preferred construction for accumulating and aligning the fruit at the pick-up point comprises multiple interconnecting ramps of different inclinations to further assure a continuous supply of fruit at the pick-up point.Type: GrantFiled: October 28, 1983Date of Patent: April 29, 1986Assignee: Sunkist Growers, Inc.Inventors: Paul F.

Patent number: 4476982Abstract: Method and apparatus for grading articles, particularly lemons, according to their surface color. The apparatus measures each lemon's reflectance in infrared, red and green wavelength bands, and computes the ratio of the red and infrared measurements and the ratio of the red and green measurements. If the red/infrared ratio is less than a prescribed crossover threshold, the apparatus compares the red/infrared ratio to a first set of thresholds, to grade the lemon into either a very dark green, dark green or light green color grade. Conversely, if the red/infrared color ratio is greater than the crossover threshold, the apparatus compares the red/green ratio to a second set of thresholds, to grade the lemon into either a silver, tree-ripe or bronzy color grade.Type: GrantFiled: October 7, 1982Date of Patent: October 16, 1984Assignee: Sunkist Growers, Inc.Inventors: Paul F. Paddock, William G. Krage, Tim D. Conway

Patent number: 4330062Abstract: A method and apparatus for grading and sorting articles, particularly fruit, according to size, surface blemish and surface color. Fruit is passed sequentially through a camera array which scans the surface of each fruit and measures the intensity of light reflected from successive discrete surface segments. Significant differences between such measured intensities are detected and a measurement of surface blemish is generated in accordance therewith. Size measurements are derived by counting the total number of segments in the surface of each fruit. Color measurements are derived by averaging the ratio of red light intensity to infrared light intensity reflected from each of a plurality of surface areas of each fruit. The fruit are separated and delivered to separate receivers by a mechanism responsive to the size, blemish and color measurements of the respective fruit.Type: GrantFiled: February 19, 1980Date of Patent: May 18, 1982Assignee: Sunkist Growers, Inc.Inventors: Tim D. Conway, Paul F. Paddock

Patent number: 4244763Abstract: Method for labeling objects including fruits supplied to a labeling station by an endless conveyor. Labels on a carrier tape are moved from a supply reel by a knurled roller which impresses a surface weakening pattern on each label so it will readily conform to a non-planar surface of the object. The tape is formed into a feed storage loop by an oscillatable tension regulating arm which controls actuation and deactuation of the knurled roller. An indexing tape segment passes through an indexing block in a transfer station, where each entering label is sensed by a detector. Indexing movement of the tape is initiated by an object detector on the conveyor. Indexing moves the tape around a sharp bend to strip the detected label from the tape and position it in a label holding frame.Type: GrantFiled: August 18, 1978Date of Patent: January 13, 1981Assignee: Sunkist Growers, Inc.Inventors: Miquel A. Varon, Paul F. Paddock

Patent number: 4033450Abstract: A conveyor having a single row of receptacles to seat individual fruit of a corresponding row of citrus fruit moves the fruit in succession past a station where it is required that the major axis of each fruit, i.e., the axis through the stem and blossom ends of the fruit be parallel to the direction of travel of the fruit. In each receptacle the individual fruit rests on a pair of parallel power-actuated spool-shaped rollers the axes of which are parallel to the direction of travel of the receptacles, which rollers spin the fruit to cause the major axes of the fruit to be oriented parallel to the direction of travel. Each receptacle is detachably mounted to transverse rods.Type: GrantFiled: November 24, 1975Date of Patent: July 5, 1977Assignee: Sunkist Growers, Inc.Inventors: Paul F. Paddock, Jerry W. Cramer

Patent number: 3961701Abstract: A conveyor having an endless series of holders equipped with cushions to carry fragile objects has an upper run extending from a receiving station to a discharge station and a lower return run with an upward arcuate return path from the lower run to the start of the upper run. The holders are turned upside down on the lower run of the conveyor and are subject to centrifugal force on the upward arcuate return path. The cushions are envelopes of flexible sheet material containing masses of pellets. A free-falling object lands on a cushion at the receiving station of the conveyor and is decelerated without harm by forming a seating recess in the mass of pellets. The return journey of the cushions redistributes the pellets to eliminate the seating recesses and thus enables newly received objects at the receiving station to be decelerated by forming new seating recesses.Type: GrantFiled: July 10, 1974Date of Patent: June 8, 1976Assignee: Sunkist Growers, Inc.Inventors: Paul F. Paddock, Jerry W. Cramer

Patent number: 3930994Abstract: Apparatus and method for automatically evaluating articles particularly citrus fruits, on the basis of the uniformity and non-uniformity of their transparency to light rays and selectively separating them into different grades according to such evaluations, the fruit being oriented and carried by a conveyor in a path between a light ray source and light ray detectors positioned to straddle the fruit core portion, the signals from the detectors being carried to an internal quality computer controlled by timing sensors responsive to fruit movement through the light rays, wherein the percentage of internal damage is computed for each fruit, after which the fruits are successively separated into different predetermined grades according to their respective damage evaluations.Type: GrantFiled: October 3, 1973Date of Patent: January 6, 1976Assignee: Sunkist Growers, Inc.Inventors: Tim D. Conway, Paul F. Paddock

Patent number: 3930995Abstract: In a system for classifying objects, particularly fruits, which pass successively through an inspection station for evaluation according to respective grades and for generating evaluation signals corresponding to such grades. The inspected fruits are then delivered to a distribution apparatus by means of a sorting conveyor having a single row of traveling holders for the individual fruits. The sorting conveyor has a plurality of discharge stations corresponding to the different evaluation grades and, when a holder carrying a fruit reaches a discharge station that corresponds to the evaluation grade for that particular fruit, the generated evaluation signal for that particular fruit causes the holder to discharge the fruit.Type: GrantFiled: August 19, 1974Date of Patent: January 6, 1976Assignee: Sunkist Growers, Inc.Inventors: Paul F.
