Automatic corn sorting and inspection system
First Claim
1. An automatic corn sorting and inspection system comprising;
- a plurality of grading and removal stations, each station including a means to sense a particular characteristic of an ear of corn;
means to convey an ear of corn past each of said stations, said plurality of stations comprising a short ear grading and removal station comprising means to inspect the length of an ear of corn, an unhusked ear grading and removal station including means to determine if ears of corn contain all or a portion of their husks, and a kernel damage grading and removal station including means to inspect substantially all of the kernels of said ear of corn for damage;
each of said stations further including means to remove ears of corn from said conveying means, said means to inspect damaged kernels comprising a plurality of fiber optic tubes positioned above said conveying means and means to transmit light through said optic fiber tubes, means mounting said fiber optic tubes and spring means associated with the mounting means for movement thereof rectilinearly, the ends of said fiber optic tubes being capable of following the contour of the ears of corn which pass through said kernel damage grading and removal station.

Abstract
A corn sorting and inspection system automatically inspects various characteristics of ears of corn positioned on an endless conveyor and moved past a series of consecutive grading and removal stations, ears of corn not having charcteristics in conformance with predetermined standards set at each station are removed from the conveyor system at the end of the particular station, thereby sorting those ears of corn which meet the predetermined standards from those which are considered flawed. The ears of corn are positioned lengthwise parallel to the direction of movement and in a single file on the endless conveyor and passed through each of the individual grading and removal sections, the ears of corn being automatically inspected for smut, short ears, unhushed ears, cob diameter and kernel damage. Each grading and removal station grades or inspects the individual ears as they pass under or through standard L.E.D. scanners which sense certain light reflective characteristics of the ear of corn or length of time required for the ear to pass the sensing device.

4. An automatic sorting and inspection system for articles of food, comprising a plurality of grading and removal stations, each station including means for sensing a particular characteristic of the articles, means for conveying each of the articles through each of the stations, and means for removal of the articles from the conveying means at each of the stations, said sensing means including a plurality of fiber optic tubes having ends positioned above said conveying means, means for transmitting light through said optic fiber tubes, mounting means for anchoring the ends of the optic fiber tubes and spring means connected to the mounting means for rectilinear movement thereof to enable the ends of the optic fiber tubes to follow contours of the articles during travel on the conveying means.
