Description

NETTING CHUTES WITH RIBBED FLOORING FOR MANUAL
AND/OR AUTOMATED CLIPPING PACKAGING APPARATUS
Field of the Invention The present invention relates to apparatus that can enclose products in packaging materials, and may be particularly suitable for enclosing products in clippable netting material.
Background of the Invention Certain types of commodity and/or industrial items can be packaged by placing the desired product(s) in a covering material and then applying a closure clip or clips to end portions of the covering material to secure the product(s) therein. For non-flowable piece goods, the piece goods can be held individually in a respective clipped package, or as a group of goods in a single package.
The covering material can be any suitable material, typically a casing and/or netting material.
Generally described, when packaging a piece good product in netting, the product is pushed through a netting chute. The product can include, by way of example, a non-flowable semi-solid and/or solid object such as a meat product including whole or half hams, turkeys, chickens, and the like. The netting chute holds a length of a netting sleeve over the exterior thereof. A first downstream end portion of the netting is typically closed using a first clip. As the product exits the netting chute, it is covered with the netting. The netting can be held relatively tight (typically stretched or in tension) over the product. The open end of the netting (upstream of the product) is then gathered and another clip can be applied to the gathered netting, typically using a double clipper apparatus. A
clip attachment apparatus or "clippers" are well known to those of skill in the art and include those available from Tipper Tie, Inc., of Apex, NC, under product numbers Z3214, Z3202, and Z3200. Examples of clip attachment apparatus and/or packaging apparatus are described in U.S. Patent Nos. 3,389,533;
3,499,259; 4,683,700; and 5,161,347.
The double clipper apparatus concurrently applies two clips to the netting proximate the open (upstream) end of the package. One clip defines the leading end portion of the package and the other defines the trailing or second end portion of the package then being closed. A cutting mechanism incorporated in the clipper apparatus can sever the two packages before the enclosed package is removed from the clipper apparatus. U.S. Pat. No. 4,766,713 describes a double clipper apparatus used to apply two clips to a casing covering. U.S. Patent No.
5,495,701 proposes a clipper with a clip attachment mechanism configured to selectively fasten a single clip or two clips simultaneously.

Description of Embodiments of the Invention The present invention will now be described more fully hereinafter with reference to the accompanying figures, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like numbers refer to like elements throughout. In the figures, certain layers, components or features may be exaggerated for clarity, and broken lines illustrate optional features or operations, unless specified otherwise. In addition, the sequence of operations (or steps) is not limited to the order presented in the claims unless specifically indicated otherwise. Where used, the terms "attached", "connected", "contacting", "coupling"
and the like, can mean either directly or indirectly, unless stated otherwise.
The term "concurrently" means that the operations are carried.out substantially simultaneously.
In the description of the present invention that :follows, certain terms are employed to refer to the positional relationship of certain structures relative to other structures. As used herein, the term "front" or "forward" and derivatives thereof refer to the general or primary direction that the product travels for packaging and closure;
this term is intended to be synonymous with the term "downstream," which is often used in manufacturing or material flow environments to indicate that certain material traveling or being acted upon is farther along in that process than other material.
Conversely, the terms "rearward" and "upstream" and derivatives thereof refer to the directions opposite, respectively, the forward and downstream directions.
Embodiments of the present invention are particularly suitable for applying closure clips to discrete objects held in a covering material. The covering material may be natural or synthetic and may be a casing material that can be sealed about a product or may be netting. The casing can be any suitable casing (edible or inedible, natural or synthetic) such as, but not limited to, collagen, cellulose, plastic, elastomeric or polymeric casing. The term "netting" refers to any open mesh material in any form including, for example, knotted, braided, extruded, stamped, knitted, woven or otherwise. Typically, the netting is configured so as to be stretchable in both axial and lateral directions (i.e, elastic, and typically isotropically elastic).
Netting or other covering material may be used to package discrete meat products such as loaves of meat, boned ham, spiral-sliced ham, deboned ham, turkey, turkey loaves held in molds, or other meat; the packaging may be formed on the item alone or with the items held in subcontainers and/or wraps such as molds, trays, boxes, bags, absorbent or protective sheets, sealant, cans and the like. Other embodiments of the present invention may be directed to package other types of food such as cheese, bread, fruit, vegetables, and the like. Examples of non-food items that may be packaged using embodiments of the present invention include living items such as flora, trees, and the like, as well as inanimate objects. Additional examples of products include discrete, semi-solid or solid non-flowable objects such as firewood, pet food (typically held in a container if the wet type), recreational objects (such as balls), or other solid or semi-solid objects. The product may be for any suitable industry including horticulture, aquaculture, agriculture, or other food industry, environmental, chemical, explosive, or other application. Netting may be particularly useful to package ham or turkeys, manufactured hardware such as automotive parts, firewood, explosives, molded products, and other industrial, consumable, and/or commodity item(s).
Generally stated, embodiments of the present invention are directed to the packaging of piece goods or discrete items by forcing them through a product chute, wrapping or enveloping the objects at the other end of the chute in a covering material, such as netting, then clipping the covering material with a closure clip or other attachment means to close the covering and hold the object or objects inside of the covering material. As noted above, clippers are available from Tipper Tie, Inc., of Apex, North Carolina. Examples of suitable clips include metallic generally "U"-shaped clips also available from Tipper Tie, Inc., in Apex, North Carolina.
Other clips, clip materials and clip configurations or closure means may also be used.
Figure 1 illustrates an exemplary automatic clipping packaging apparatus 10 according to embodiments of the present invention. As shown, the apparatus 10 includes a product pusher assembly or mechanism 20, a product chute 30, and a clipper 40. It is noted that the clipper 40 may be referred to herein as a clipper apparatus, clipper mechanism, and/or clipper assembly, but each term may be used interchangeably with the others. As shown, the apparatus 10 may optionally include an infeed conveyor 50. In the embodiment shown, the apparatus 10 can be described as a horizontal automatic clipping packaging apparatus as the product is primarily moved, processed, clipped and packaged in a horizontal plane. However, certain components, features or operations may be oriented and/or carried out in other planes or directions and the present invention is not limited thereto. For example, the product chute 30 may be tilted from horizontal, typically so that the discharge or egress end 30d is closer the ground-than the product entry or ingress end 30e.
The direction of travel of an exemplary product undergoing packaging is illustrated by the broken line arrows in Figure I.
This positioning of the product in the flow path and/or alignment with the product chute cavity 30c (Figures 3, 4 and 9) can be carried out substantially automatically as will be discussed further below. However, a target product undergoing packaging can also be manually introduced or placed into the flow path and subsequently processed as in an automatic in-feed operation.
In operation, the product pusher assembly 20 linearly retracts and advances to push a product through the product chute 30 so that the product is positioned proximate the clipper 40 and then retracts to a resting state upstream of the product transfer zone 60.. As described above, a sleeve of covering material 100c (see Figure 2B) can be positioned about the external surface of the product chute 30 and configured to be drawn downstream thereof so as to automatically encase the product as the product emerges from the discharge end 30d of the product chute 30. A
supplemental sleeve material holder may also be used if desired instead of placing the sleeve of casing material on the product chute. The supplemental sleeve holder can be configured to surround a downstream portion of the product chute (not shown).
The sleeve of covering material may be sized to stretch to substantially conform to the external wall or surface of the product chute 30 or may be more loosely held thereon.
The cavity of the product chute 30c (Figures 3, 4 and 9) may be sized to snugly contact or squeeze opposing portions of the product (side to side and/or top to bottom) as the product is pushed therethrough or may be oversized with respect to the product so that the product loosely travels therethrough.
In some embodiments, the shape, size and/or type of product can determine a suitable netting diameter to provide a desired tightness of netting and, hence, influence the product chute design factor.
In operation, the sleeve of covering material may be clipped, welded, fused, knotted or otherwise closed at a leading edge portion thereof. When the product exits the product chute 30, it is held in the covering material as the covering material is drawn downstream. The covering material is typically loaded onto the product chute 30 and the leading edge portion closed before the product chute 30 is mounted to the apparatus 10. Additional description of a suitable automatic apparatus is described in U.S. Patent No. 7,581,369.
Figures 2A-2D illustrate a manual or semi-manual system 11 with a series of operations that can be used to package a target product 100 or products using a product chute 30 and a desired covering material 100c. Figure 2D illustrates a clipped 100c1 package of netting enclosing the product 100.
Figure 3 illustrates one embodiment of a product chute 30 that can be used with automatic and/or manual packaging systems. As shown, the product chute 30 includes an outer surface 30s, a cavity 30c, and a floor 30f. In this embodiment, the product chute floor 30f includes at least one (shown as a single) axially extending rib 30r that has a height such that it extends vertically above the adjacent portions of the floor 30f. The term "rib" means a projecting generally axially extending member that is sized and configured so that it can influence the movement and/or positioning of a product 100 as the product enters and/or travels through the chute 30.
As shown, the floor 30f can be substantially planar and disposed at the lower portion of a curvilinear wall 30w. In certain embodiments, the chute is configured so that the curvilinear wall 30w terminates or merges into the floor 30f to together define a non-circular cross-sectional shape of the cavity 30c.
Thus, in certain embodiments, the product chute 30 has a cross-sectional profile that is non-circular. As shown in Figure 3, the product chute 30 may he configured with a planar bottom portion and generally semi-circular side portions.
Other cross-sectional profile configurations may also be used including, but not limited to, circular, oval, triangular, rectangular, square and the like.
The product chute body may include a single continuous wall that defines the shape of the cavity 30c above the floor 30f. In other embodiments, the product chute body can be formed with a plurality of walls. In some embodiments, the product chute 30 is fabricated from stainless steel. The interior surface or portions thereof may be coated with an anti-stick coating and/or lubricant. For example, the interior of the chute 30 may comprise TEFLON
polymer. In particular embodiments, a single sheet of sheet metal can be formed to provide the desired product chute body shape.
As shown, the rib 30r is disposed such that is offset from the center of the cavity 30c, although in some embodiments the rib 30r may be centered on the floor 30f. The rib 30r can be positioned adjacent a lower portion of the curvilinear wall 30w. Typically, the rib 30r includes a ramped forward edge portion 30r that inclines or rises to a peak 32. The ramped forward edge portion 30r may have a planar surface segment 31 that tapers in width as the ramped portion rises. The segment 31 can have a width that is wider adjacent the floor 30f than the width closer to the peak 32.
As is also shown, the product chute 30 may include an outwardly flaring edge portion 34 that gradually tapers into the primary chute body. Thus, the product chute 30 can include a larger front-end cavity area relative to the intermediate and/or discharging portion 30d, i.e., the chute cavity 30c narrows in the pushing/product travel direction. Thus, the product chute 30 can include a primary body and a larger upstream guide portion that narrows into the shape of the primary body. The chute 30 may be formed as a unitary member or a series of attached members (not shown).
In operation, a supply of covering material 100c can be placed on or about the chute 30 and arranged to surround the exterior surface of at least a portion of the product chute 30. The covering material 100c stretches in tension in the downstream direction to cover the product (tenting in the axial direction) as the product exits the discharge end portion of the product chute 30d. In certain embodiments, the covering material is configured and sized to stretch in at. least the lateral direction and typically in both the lateral and axial directions as it is held on and dispensed from the product chute 30.
The product chute 30 can include a handle 35 or other suitable gripping means thereon to facilitate operator handling. In addition, the product chute 30 may include a mounting bracket 36 that allows the chute 30 to be secured to a mounting frame during operation. Although the product chute 30 is shown as having a continuous outer surface or wall, other configurations may also be used. For example, the chute wall or walls may include a slot or apertures and may not be a closed configuration, typically depending on the application.
