  • Patent number: 5560190
    Abstract: Method for the automated harvesting of headed row crops, including lettuce, optionally leaving at least the crop root in the ground, and an apparatus to practice the method. The present invention provides a methodology to locate crop stems, separate the outer leaves from the head, grip the stem and harvest the head. Gripping the stem is accomplished with at least one pneumatic gripping bladder. Substantially simultaneous to gripping the head, the head is separated from the core and stem. One method to accomplish this separation is by means of a pair of differential pneumatic bladders which frees the head from the core at the center of the head, leaving the core and the outer leaves attached to the stem and root. Alternatively, a second separation method taught herein is the application of a downward force applied to the top of the head by a pneumatic bladder. The two separation schemes may be used conjointly or in the alternative.
