US Patent:

20110293797, Dec 1, 2011
Filed:

May 28, 2010
Appl. No.:

12/790777
Inventors:

Rosser W. PRYOR - Fayetteville GA, US
Stephan C. Robinson - Carmel CA, US
Roger D. Billingsley - Laguna Niguel CA, US
Stephen Chris Jens - Winchester MA, US
Frank E. Davis - Chicago IL, US
Robert Ragon - Lake Wylie SC, US
Assignee:

DOLE FRESH VEGETABLES, INC. - Monterey CA
International Classification:

B23Q 15/00
A23N 15/04
A23P 1/00
A23N 15/02
US Classification:

426231, 99635, 99643, 83 72
Abstract:

A system for trimming a lettuce head using a digital imaging system and cutting mechanism. The lettuce head is conveyed between a lower feed conveyor and an upper feed conveyor that is disposed a fixed distance over and substantially aligned with a lower feed conveyor. The digital imaging system is configured to capture an image of the lettuce head and determine a cutting profile using the image. The cutting mechanism is disposed over the lower feed conveyor and includes: a servo motor mechanically coupled to a drive shaft; an armature with a pivot end mounted to the drive shaft and a sweep end disposed a radial distance from the pivot end; a cutting nozzle, mounted to the sweep end of the armature, configured to trim the lettuce head; and servo-control circuitry configured to articulate the cutting nozzle through a cutting arc based on the cutting profile.
