An automated apparatus (100), a system (1000), and method (M) for packing leafy produce (10) into a tray (20) involving a plunger (30), the plunger (30) having an actuator arm (40) and a footpad (50), the footpad (50) having an upper surface (50a) and a lower surface (50b), being in moveable relation to the actuator arm (40), for contacting the leafy produce (10).
The present invention relates to agricultural apparatuses, systems, and methods. More particularly, the present invention relates to agricultural apparatuses, systems, and methods for processing produce. Even more particularly, the present invention relates to agricultural apparatuses, systems, and methods for packing processed produce.
BACKGROUND ARTThe currently existing art involves several machines for packing leafy produce, such as “spring mix,” spinach, lettuce, endive, arugula, mache, herbs, and the like. One such invention is a packing machine which fills a container with leafy produce, fits a lid onto such container having the produce, but damages the leafy produce at the rim of the container, thereby shortening the shelf life of the product. This problem in the related art occurs, because the leafy produce has a tendency to spring back upon loading into the container, to overhang the rim of the container, and to be subsequently damaged during fitting of the lid. To counteract this adverse result, agricultural processors have used manual labor for “post-packing” the leafy produce, e.g., using a production line of approximately six gloved workers who manually reposition the leafy produce in the container prior to thereon fitting the lid. Thus, a long-felt need is seen to exist for an automated apparatus, a system, and a method for efficiently packing leafy produce, eliminating damage thereto, and minimizing processing time.
DISCLOSURE OF THE INVENTIONThe present invention involves an apparatus, a system, and a method for efficiently packing aproduct, such as leafy produce, eliminating damage thereto, and minimizing processing time. The present automated apparatus for packing leafy produce into a tray generally comprises a plunger, the plunger having an actuator arm and a footpad, the footpad having an upper surface and a lower surface and being in moveable relation to the actuator arm for contacting and plunging the leafy produce into the tray.
The present automated system for packing leafy produce into a tray generally comprises a conveyor, having a stepper for accommodating and moving a tray, a hopper for channeling the leafy produce, a feeder for receiving the channeled leafy produce and for filling the leafy produce into the at least one tray; and an automated packing apparatus for packing the leafy produce into the tray, the apparatus comprising a plunger, the plunger having an actuator arm and a footpad, the footpad having an upper surface and a lower surface and being in moveable relation to the actuator arm for contacting and plunging the leafy produce into the tray.
The present invention automated method for packing leafy produce into a tray generally comprises the steps of conveying and stepping a tray; channeling the leafy produce through a hopper; feeding the channeled leafy produce into the tray, thereby filling the tray; providing an automated packing apparatus for packing the leafy produce into the tray, the apparatus providing step comprising providing a plunger, the plunger providing step comprising providing the plunger with an actuator arm and a footpad, the footpad having an upper surface and a lower surface and being in moveable relation to the actuator arm for contacting and plunging the leafy produce into the tray; providing a sensor for detecting the presence of the tray and for supplying an electronic signal to the feeder to effect its opening for filling the tray with the leafy produce; packing the leafy produce into the tray using the automated packing apparatus; and applying a lid to the tray.

BRIEF DESCRIPTION OF THE DRAWINGFor a better understanding of the present invention, reference is made to the below-referenced accompanying Drawing. Reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the Drawing.
By example only, the articulating structure 40a comprises a feature selected from a group consisting essentially of a hinge, a pin, and a ball and socket combination. The at least one footpad 50 comprises a corrugated surface 50c at the lower surface 50b for minimizing surface tension of the leafy produce 10 which facilitates release of the leafy produce 10 from the footpad 50 when the plunger 30 retracts. The corrugated surface 50c comprises a configuration such as a sinusoidal profile and a square wave profile, the sinusoidal profile being preferred. The at least one actuator arm 40 comprises a structure for adjusting stroke (not shown), wherein the stroke is effected by programmable logic control (PLC), such as a magnetic read switch disposed on the actuator arm 40 and a PLC-defined dwell time. The actuator arm 40 comprises an actuator arm housing 40b such as a hollow tube. The at least one footpad 50 comprises a structure for adjusting size (not shown), especially the planform size. The footpad size adjusting structure comprises a feature such as at least one retractable footpad portion and a set of interchangeable footpads 50 which are interchangeable by loosening a fitting 41a at a proximal end of a guide-rod 41 and a fitting 50d at the upper surface 50a of the footpad 50, wherein each footpad 50 of the set comprises a distinct size.
Preferably, the plunger 30 is angularly disposed in relation to the tray 10. The plunger 30 is activated, i.e., deployed by a feedback and control unit comprising sensor 110 (discussed, infra), upon sensing the presence of a tray 20 and retracted upon packing the tray 20 with the leafy produce 10. The apparatus 100 comprises a primary plunging mechanism 31, as shown and described, infra, with respect to
By example only, the present system 1000 further comprises a tray denester 140 (not shown) which removes two trays 20 from two magazines 150 (not shown) using a vacuum technique, such as air suction. The tray denester 140 receives a signal for supplying the trays 20 to a conveyor 60 having a stepper 70 (not shown). The vacuum technique involves a vacuum device (not shown) such as a cam and cylinder apparatus which travels upward to the waiting trays 20, contacts the bottom of the trays 20, pulls two trays 20 on a downstroke, releases those two trays 20 on the conveyor 60. The gas puff facilitates alignment of the trays 20 on the conveyor 60. The conveyor 60 runs the length of a processing line which may be twenty-five feet, for example, and is operated by a control panel (not shown) that imparts a signal which indicates the stepping distance for the conveyor 60, as shown and described with respect to

The feeder 90 includes a product transfer chute 120 or a funnel being disposed into the at least one tray 20 upon receipt of the electronic signal from the sensor 110. In the alternative, the plunger 30 is disposed within the product transfer chute 120. The system 1000 further comprises the following features: a structure (not shown) for applying at least one lid 130 to each respective at least one tray 20, a structure (not shown) for labeling an upper surface of the at least one lid 130 and a lower surface of each respective at least one tray 20, and a structure (not shown) for vibrating the at least one tray 20 to assist settling and packing of the leafy produce 10. The structure for applying the lid 130 comprises a lid denester 145 (not shown) which operates in a manner similar to that of the lid denester 140, i.e., using a vacuum technique involving a cam and cylinder combination. Finally, the system 1000 further comprises a security banding device for applying a polymeric band to the rim of the lidded tray (not shown).
