Abstract: An automatic corn cutting apparatus for cutting kernels off of husked ears of corn. The ears may be presented to the cutting knives either tip end or butt end first. The ears are fed into the cutting knives by a pair of drive rollers carried by a pair of articulating drive shafts. The drive shafts move in a plane perpendicular to the axis along which the ears are fed to the cutting knives. A sensor, preferably a linear variable differential transformer, or LVDT, is carried by one of the drive shafts remotely from the ears, i.e. the LVDT does not contact the ears. The sensor detects the profile of each ear of corn, and the profile is used by a knife controller to efficiently remove the kernels from each ear of corn.

Abstract: An apparatus and method for automatically cutting kernels off ears of corn with reduced damage to the kernels are provided. A circular array of movable kernel cutting knives rotates around an axis of rotation. Singulated ears of corn are conveyed along the axis of rotation into and through the array of kernel cutting knives. A sensor is provided for sensing the size and shape of each ear of corn prior to the ear being conveyed into the array of cutting knives and a knife controller moves the array of cutting knives relative to the axis of rotation in response to input from the sensor to efficiently cut the kernels off the cob with reduced damage to the kernels. The ears may be presented to the kernel cutting knives either tip end or butt end first. The cutting depth of the knives may be varied to compensate for variations in thickness of the kernels. In one embodiment, the ears may be presented to the kernel cutting knives with their husks attached.
