Abstract
An automated machine for packing leafy produce into a tray involving a plunger, the plunger having an actuator arm and a footpad, the footpad having an upper surface and a lower surface, being in moveable relation to the actuator arm, for contacting the leafy produce.
Description
- This application is a continuation in part of application Ser. No. 11/232,830, entitled “Automated Plunger assembly, Machine and Method” filed on Sep. 21, 2005 (retitled “Apparatus for Packing Leafy Product into a Tray” by examiner's amendment), and claims priority thereto. The parent application and all amendments thereto are hereby expressly incorporated by reference. Claims 1 through 8 herein were previously allowed in the parent application. Claims 9 through 16 are new.
- The present invention relates to mechanized processing and packaging of agricultural products and produce.
- The currently existing art involves several machines for packing leafy produce, such as “spring mix,” spinach, lettuce, endive, arugula, and the like. One such instance of existing art is a packing machine that fills a container with leafy produce then 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 for efficiently packing leafy produce, eliminating damage thereto, and minimizing processing time.
- The present inventive concept pertains to the mechanized packing of a product, such as leafy produce, into a tray without damage and minimizing processing time. In a preferred embodiment, an automated machine for packing leafy produce into a tray generally comprises: one or more transfer chutes for receiving the portions and guiding each tray-sized individual portions into one of the trays; flop gates within the chutes to control the flow of produce through the various chutes; a conveyor for moving the trays into a position below the transfer chute's discharge opening to receive the tray-sized portions; a plunger assembly with at least one linear plunger having a first footpad for moving the portions through the transfer chute discharge opening into the tray, a ram, cylinder and piston rod, a retracted first position with the footpad outside of the transfer chute and an extended second position with the footpad inside the transfer chute proximal to the discharge opening. Mechanized moving parts, including the flop gates and plunger assembly, are coupled with automated actuators to allow automation and sequencing of movement.
- Advantages of the present inventive concept include the promotion of increased production levels, minimization of rejected product, and minimization of the number of workers required in the production line. Other features of the present inventive concept and its embodiments are disclosed, or are apparent, in the section entitled “Detailed Description of the Invention,” disclosed, infra.

FIGS. 1 and 8 , theautomated machine 1000 for packing leafy produce 10 into atray 20, comprises aconveyor 60 having a stepper 70 for accommodating and moving at least onetray 20, a tray filler generally comprising a hopper 80 for channeling the leafy produce 10 and a feeder 90 for receiving the channeled leafy produce 10 and for filling the leafy produce 10 into the at least onetray 20, and anautomated plunger assembly 100 for packing the leafy produce 10 into atray 20, theapparatus 100 comprising at least oneplunger 30, each at least oneplunger 30 having at least oneactuator arm 40 and atleast footpad 50, the at least onefootpad 50 having anupper surface 50 a and alower surface 50 b, being in moveable relation to the at least onerespective actuator arm 40, for contacting the leafy produce 10. -
Machine 1000 further comprises a sensor 110 for detecting the presence of the at least onetray 20 and for supplying an electronic signal to the feeder 90 to effect its opening for filling the at least onetray 20 with the leafy produce 10 (a designated amount thereof). The feeder 90 includes aproduct transfer chute 120 or a funnel being disposed into the at least onetray 20 upon receipt of the electronic signal from the sensor 110. In the alternative, theplunger 30 is disposed within theproduct transfer chute 120. -
FIGS. 9 though 16 similarly depict a packing machine and its components with a preferred configuration, having a plunger assembly comprising only one plunger per transfer chute. This embodiment has the advantage of fewer moving parts, with consequent added simplicity in coordinating and automating the plunger actuation as well as being easier to clean, maintain and sanitize. - Information as herein shown and described in detail is fully capable of attaining the above-described object of the invention, the presently preferred embodiment of the invention, and is, thus, representative of the subject matter which is broadly contemplated by the present invention. The scope of the present invention fully encompasses other embodiments which may become obvious to those skilled in the art, and is to be limited, accordingly, by nothing other than the appended claims, wherein reference to an element in the singular is not intended to mean “one and only one” unless explicitly so stated, but rather “one or more.” All structural and functional equivalents to the elements of the above-described preferred embodiment and additional embodiments that are known to those of ordinary skill in the art are hereby expressly incorporated by reference and are intended to be encompassed by the present claims.
- Moreover, no requirement exists for a device or method to address each and every problem sought to be resolved by the present invention, for such to be encompassed by the present claims. Furthermore, no element, component, or method step in the present disclosure is intended to be dedicated to the public regardless of whether the element, component, or method step is explicitly recited in the claims. However, various changes and modifications in form, material, and fabrication material detail may be made without departing from the spirit and scope of the inventions as set forth in the appended claims should be readily apparent to those of ordinary skill in the art. No claim herein is to be construed under the provisions of 35 U.S.C. 112, sixth paragraph, unless the element is expressly recited using the phrase “means for.”
- The present invention industrially relates to agricultural apparatuses, machines, and methods. More particularly, the present invention industrially relates to agricultural apparatuses, machines, and methods for processing produce. Even more particularly, the present invention industrially relates to agricultural apparatuses, machines, and methods for packing processed produce.
Claims (16)
1. An apparatus for packing leafy produce into a tray, comprising:
a. A primary chute for receiving and apportioning the leafy produce into individual portions;
b. A transfer chute, having two sidewalls, two end walls and a discharge opening, for receiving the portions and guiding each of said tray-sized individual portions through a discharge opening into one of the trays;
