Description

BACKGROUND OF THE INVENTION

This invention generally relates to an apparatus for cutting elongated meat and, more particularly, to an apparatus for cutting elongated meat into a plurality of separated strips.
In the preparation of meat products, it is useful to process relatively larger portions of meat, such as a pre-manufactured hot-dog or sausage, into smaller portions or strips of meat. Such individual strips of meat can be used to form many meat products. For example, the individual strips of meat can be battered, breaded and fried to form a “fun” to eat French fry type of meat product.
Slicing meat into various relatively small portion of meat is a time consuming and tedious process when carried out by hand. Additionally, the size of the sliced portions will vary and is difficult to keep consistent and to produce a large quantity. More problematic is the inherent danger in using a knife or other sharp cutting device to manually slice a portion of meat, as the knife can easily slip from the meat and cut the hand and/or other parts of the person cutting the meat. Known automated meat cutters have difficulty centering the meat with respect to the cutting blades.
What is needed is an apparatus capable of safely, simply and rapidly processing portions of meat into smaller pieces of meat.

DETAILED DESCRIPTION OF THE INVENTION

Certain terminology is used in the following description for convenience only and is not limiting. The words “right”, “left”, “lower” and “upper” designate directions in the drawings to which reference is made. The words “inwardly” and “outwardly” refer to directions toward and away from, respectively, the geometric center of an apparatus for cutting elongated meat in accordance with the present invention, and designated parts thereof. Unless specifically set forth herein, the terms “a”, “an” and “the” are not limited to one element but instead should be read as meaning “at least one”. The terminology includes the words noted above, derivatives thereof and words of similar import.
Referring to the drawings in detail, wherein like reference numerals indicate like elements throughout, there is shown in FIGS. 1-5B a preferred embodiment of an apparatus, generally designated 10, for cutting elongated meat in accordance with the present invention. The apparatus 10 is for cutting an elongated piece of meat 12 into at least two, but preferably eight, separated elongated strips of meat 14, each strip of meat 14 having a cross section generally in the shape of a pie wedge. Alternatively, referring to FIG. 2B, the apparatus 10 may cut the elongated meat 12 into a plurality of sections of meat 14 a connected by an uncut core 14 b such that the sections of meat 14 a remain connected until separated during processing, by end user or are not separated at all. The apparatus 10 preferably processes or cuts elongated pieces of meat 12 such as hot dogs, worsts, sausages or any other similarly shaped meats. However, the apparatus 20 can also be used with foods, other than meat, having properties, such as texture or cohesion, that are relatively similar to those of meat such as tofu.
Referring to FIG. 1, the apparatus 10 includes a frame 16 having a longitudinal axis L. The frame 16 is preferably constructed of stainless steel. However, the frame 16 can be constructed of any suitably strong, durable and non-corrosive material such as aluminum or some other metal or alloy. The frame 16 preferably includes a support stand 18 that elevates the frame 16 above a support surface 26 such as a floor. The support stand 18 preferably includes four vertical struts 20. Crossbars 22 are preferably used to connect the struts 20 and vertically adjustable feet 24 support each strut 20 from the support surface 26. The feet 24 are preferably individually adjustable in the axial direction to compensate for differences in the height of the support surface 26 to level the frame 16 if the support surface 26 is non-planar and/or tilted.
Referring to FIG. 4, a motor 28 is located proximate to the frame 16 and is preferably mounted to a support bar (not shown) extending from the frame 16. However, the motor 28 may be mounted directly to the frame 16, the support stand 18 or a separately provided structure (not shown). The apparatus 10 preferably only requires a single electric motor 28 as described further below.
Referring to FIGS. 3, 4 and 5A-5B at least two, but preferably eight, generally circular cutting blades 32 are rotatably mounted to the frame 16 each about its own respective blade axis A (FIGS. 5A and 5B). The blades 32 have a sharpened outer peripheral edge and are preferably formed of hardened stainless steel similar to that used in standard meat cutting blades and have a thickness of approximately 0.125″. The thickness of the blades 32 may be varied depending on the type of elongated meat 12 being cut and the speed in which the blades 32 are rotated. The sharpened outer peripheral edge of each blade 32 is preferably smooth but may be jagged or roughened to aid in pulling the elongated meat 12 along the longitudinal axis L.
Each blade axis A is generally perpendicular to the longitudinal axis L and the blades axes A are positioned generally on an imaginary plane generally perpendicular to the longitudinal axis L. As shown in FIG. 5A, each blade 32 is preferably generally tangent to the longitudinal axis L such that the elongated meat 12 is cut into completely separated strips of meat 14 (shown in FIG. 2A) rather than cut grooves into the elongated meat 12. However, the blades 32 may be adjusted to be spaced from the longitudinal axis L (shown in FIG. 5B) such that sections of meat 14 a remain attached to an uncut core 14 b (shown in FIG. 2B).
Preferably, the blades 32 are equally circumferentially spaced around the longitudinal axis L and the number of blades 32 is equal to the number of strips or sections of meat 14, 14 a. In the preferred embodiment, eight blades 32 are equally circumferentially spaced around the longitudinal axis with about a forty five degree angle between each blade 32 and the eight blades 32 cut the elongated meat 12 into eight strips of meat 14 having a pie-shaped cross section. However, the blades 32 need not be equally circumferentially spaced around the longitudinal axis L and/or the blades 32 may be circumferentially spaced around a portion of the longitudinal axis L with the remaining portion being a surface such as a wall (not shown). For example, the wall may be generally parallel to the longitudinal axis L and the blades 32 may be generally tangent to the wall at the longitudinal axis L and circumferentially spaced around the remaining one hundred eighty degrees. In such a configuration, the number of blades 32 does not necessarily equal the number of strips of meat 14 produced. For example, three strips of meat 14 would result from a two blade arrangement cutting against a wall. The blades 32 all preferably rotate at the same speed and in a similar direction such that the portion of the blades 32 closest to the longitudinal axis L are all moving in the same downward direction when the blades 32 are viewed from above the apparatus 10. The symmetry of the blade arrangement helps to center the elongated meat 12 and to cut the elongated meat 12 into generally the equally sized strips of meat 14 shown in FIG. 2A.
Each blade 32 is preferably fixedly mounted to a blade axle 34. Each blade axle 34 is co-linear with and rotates about the respective blade axis A (FIGS. 3, 5A and 5B). Each blade axle 34 is rotatably mounted to the frame 16 through an axle mount 36 having a sleeve bearing 36 b. Each axle mount 36 is preferably movably mounted to the frame 16 by at least one, and preferably two, adjustable mounts 62 such that the axle mount 36 and the respective blade 32 is radially adjustable with respect to the frame 16 toward and away from the longitudinal axis L to allow for adjustments if necessary and/or to leave the sections of meat 14 a attached to an uncut core 14 b (FIG. 5B). Each adjustment mount 62 preferably includes a threaded shaft 62 a fixedly mounted to a block 36 a and extends through the frame 16. The shaft 62 a is preferably secured to the frame 16 by a pair of nuts 62 b. However, the axle mounts 36 may be fixedly mounted to the frame 16 or adjustably mounted in a different manner such as through a rack and pinion arrangement. Though it is preferred that the frame 16 have a hoop-type arrangement, the frame 16 may be more of a plate (not shown) with a center opening. Additionally, through the blades 32 are preferably independently adjustable with respect to the longitudinal axis L, the blades 32 may be simultaneously adjustable such that the blades 32 maintain an equal distance from the longitudinal axis L.
Each blade axle 34 includes a first beveled gear 38. Each axle mount 36 is preferably sandwiched between one of the blades 32 and one of the first beveled gears 38. Each first beveled gear 38 is preferably driven by a second beveled gear 40 that is perpendicular to the first beveled gear 38. Each second beveled gear 40 is mounted to a generally vertically extending drive axle 42. Each drive axle 42 is rotatably mounted to the frame 16 by a sleeve bearing (not shown). Each drive axle 42 includes a wheel or belt gear 44 extending axially below the blades 32 and generally rotatable about an axis (not labeled) that is generally parallel with the longitudinal axis L. The belt gears 44 are preferably generally co-planar and equally spaced around the longitudinal axis L to form a generally tangential octagon shape such that a single drive belt 46 contacts and drives all of the belt gears 44 simultaneously to ensure generally equal rotation of all of the blades 32 and requiring only one motor 28 to drive the drive belt 46 (see FIGS. 5A-5B). The drive belt 46 is preferably elastic such that the adjustment of the blades 32 and the belts gears 44 away from the longitudinal axis L is possible without the need for replacing the drive belt 46.
Referring to FIG. 1, the blades 32, the frame 16 and other operating components are preferably covered by a protective blade cover 60. The blade cover 60 is preferably solid, but the blade cover 60 may have openings or be made of a transparent or translucent material such that the blades 32 are visible but human body parts are kept from contacting the blades 32. The blade cover 60 is shown to have a octagon shape to match the shape of the frame 16 but the blade cover 60 may be any preferred shape so long as the rotating blades 32 and other operating components are at least partially covered. A funnel or feed tube 48 preferably extends from the blade cover 60. The feed tube 48 is preferably releasably mounted to the blade cover 60 by a collar clamp 50. However, the feed tube 48 may be fixedly attached or otherwise connected to the blade cover 60. The feed tube 48 is preferably centered around the longitudinal axis L such that elongated meat 12 which is fed into the feed tube 48 is generally aligned with the longitudinal axis L as the elongated meat 12 contacts the blades 32.
A hopper 52 is preferably provided above the feed tube 48 for holding a plurality of elongated meat pieces 12 to be cut. Though shown unattached, the hopper 52 may be attached to the blade cover 60 or frame 16. The hopper 52 preferably includes a bounce guard 54 that prevents the elongated meat 12 from falling out of alignment while the hopper 52 sequentially feeds the elongated meat 12 into the apparatus 10. The hopper 52 preferably uses gravity to advance the elongated meat pieces 12. A dispending piston 56 preferably slides horizontally back and forth to urge the bottommost elongated meat piece 12 into the feed tube 48. Though a hopper 52 is preferred to feed the elongated meat 12 into the apparatus 10, the elongated meat 12 can be fed into the apparatus 10 by any suitable method such as by being hand fed, using a conveyor feed (not shown) or a dispending roller (not shown).
Once the elongated meat 12 is fed into the feed tube 48 and contacts the blades 32, the elongated meat 12 is brought into co-linear alignment with the longitudinal axis L and the blades 32 pull the elongate meat 12 along the longitudinal axis L. Since gravity in addition to the rotation of the blades 32 is used to help to pull the elongated meat 12 through the blades 32, the longitudinal axis L is preferably vertical (i.e. perpendicular to the support surface). However, the longitudinal axis L may be angled or horizontal and rely on the blades 32 to pull the elongated meat 12 through and/or have the dispensing piston 56 or other device urge the elongated meat 12 through the blades 32. As the elongated meat 12 is pulled through the blades 32, the blades 32 cut the elongated meat 12 into the strips of meat 14.
Referring to FIGS. 1 and 4, once the elongated meat 12 is cut into strips of meat 14, the strips of meat 14 fall onto a conveyor belt 58. The conveyor belt 58 preferably extends underneath the blades 32 and is mounted to the support stand 18. However, the conveyor belt 58 need not be connected to the support stand 18. The force of the fall of the strips of meat 14 onto the conveyor belt 58 helps to ensure that any un-separated strips of meat 14 are completely separated for further processing. Preferably, the conveyor belt 58 is a vibratory conveyor that sufficiently separates and arranges the strips of meat 14 to allow the strips of meat 14 to be directly transferred through sequential battering, breading and cooking stations (not shown). Alternatively, the sections of meat 14 a may stay connected to the uncut core 14 b. Though use of a conveyor belt 58 is preferred to move the strips of meat 14 from the blades 32, the strips of meat 14 could instead be collected in a container (not shown) for later transport and processing.
It will be appreciated by those skilled in the art that changes could be made to the embodiment described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiment disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
