Description

TORTILLAS STACKER Technical Field The invention relates to a food handling apparatus and more particularly, to an improved device for counting and stacking thin, flexible food elements, such as tortillas. Cross Reference to Related Requests This application is a continuation of the provisional patent application, serial number 60 / 067,127 filed on 2/12/97, entitled "Tortilla Counter-Stacker". Prior Art The state of the art in tortilla stackers-counters is the counter-stacker manufactured by Arr-Tech Mfg; Inc. This device suffers from a severe disadvantage, in that the tortillas stacked by this device do not align coaxially, resulting in piles having broken edges, such as a pack of cards immediately after the shuffle. Also, as a packet of cards, heaps of tortillas have to be manually tapped on the sides, to obtain a cylindrical stack of smooth sides. In an industry where tortilla production is almost fully automated, this stage of manual pile alignment adds substantial labor costs. It is estimated that for tortillas, only 20% of the cost is in the product and 80% is found in the intensive labor packing processes. The alignment of the automated pile would eliminate half to two thirds of the labor involved in the packaging. Numerous innovations have been provided for the Tortilla Stackers-Counters in the prior art, which are described as follows. Although these innovations may be suitable for the specific individual purposes to which they are directed, they differ from the present invention as contrasted hereinafter. In Patent Number 4,760,777, entitled "Tortilla Stacker", invented by Richard S. Welsh, an apparatus for stacking tortillas includes a loading unit in the form of a tub-like load conveyor, for transporting a series of Mass members, while forming a small depression in each of the mass members. A container in the form of a straight hollow cylinder having a retractable loading surface is placed at the discharge end of the loading conveyor. The tortillas are piled one leftover on top of the other on the retractable loading surface, by means of the loading conveyor. A conveyor located below the container receives the pile of tortillas after the retraction of the loading surface. A counter in an inclined duct leading to the conveyor accurately counts the number of tortillas that enter the container. In Patent Number 4,006,831, entitled Automatic Tortilla Counter and Stacker, invented by James A. Jiménez, a method for stacking articles and an automatically controlled apparatus for successively receiving articles formed of a semi-rigid sheet material or rigid, such as partially cooked or cooked tortillas, or similar food products, automatically formed in an orderly fashion in piles of a predetermined number of items and then automatically taken away to pack each pile when complete. In Patent Number 4,530,632, entitled "Stacking Apparatus for Flexible, Generally Planar Food Products," invented by Richard Sela, an apparatus for counting and stacking food products such as tortillas. The tortillas are initially placed in an inlet duct that contains a large number of air vents to create an air cushion, to allow the tortilla to slide down the inlet duct onto an inclined conveyor belt. The conveyor belt is of a clear width mesh design and is supported on a belt support that has a large number of air intakes, which create a vacuum that keeps the tortilla in contact with the band. The tortillas are transported by the band, down one end of the band holder and along the underside of the band holder, maintaining contact between the tortilla and the band by the vacuum created by the air inlets formed in the support of band. The air intakes end in a location on the underside of the belt support, allowing the tortillas to fall from the conveyor belt. The tortillas fall into a stationary support formed by bars, which are interspersed with the conveyor belts, moving together as a unit. The conveyor belts are usually placed below the upper surface of the support. However, when a predetermined number of tortillas has been stacked, the band rises, thus removing the tortillas from the support. The mechanism for raising the bands is actuated by a counter, which counts a predetermined number of tortillas that pass beyond a counting station and delays the actuation of the belt lifting mechanism until the last tortilla has fallen into the support . The bands unloading the mounds of tortillas move in the opposite direction to the direction in which the tortillas are delivered to the support, in order to minimize the time required to remove the tortillas from the support before an additional tortilla can be placed in the same. . In Patent Number 5,720,593, entitled Apparatus and Method for Counting, Inspecting and Stacking Apparatus and Method of Counting, Inspecting and Stacking Planar Food Products, invented by Todd B. Pleake, an apparatus for counting, inspecting and stacking products generally flat flexible foods such as tortillas, or the like. The apparatus has an inclined feeder conveyor, with adjustable alignment guides thereon to adjust the lateral position of each tortilla as it passes to a transit conveyor. The sensors mounted on the transit conveyor count the tortillas and inspect the size and shape of the tortillas, to detect any defective tortillas that move along the transit conveyor. At the end of the transit conveyor, an arcuate shaped path guide bends the tortilla in an arched shape as the tortilla leaves the path guide and passes through a known path to a stacking mechanism. The arched shape allows the front edge of the tortilla to resist bending or folding. A reject mechanism placed between the end of the transit conveyor and the trajectory guide redirects any rejected tortilla detected by the sensors down outside the trajectory guide. A stacking mechanism receives the tortillas at the end of the path. An agitator shakes the stacking mechanism and pushes the stack of tortillas to form an aligned, well-formed stack. A movable stacking plate supports the stack of tortillas in the stacking mechanism and moves down incrementally as the tortillas are stacked in the stacking mechanism, so that the path of each tortilla is approximately the same . The stacking plate has a lowered position that deposits a stack of tortillas on a base plate and a stack removing device moves the stack of tortillas away from the stacking facility towards a discharge conveyor. In Patent Number 5,253,762, entitled "Stacking, Counting and Sorting Device for Flexible," device invented by Daryl G. Duncan, a device for counting, inspecting, classifying and stacking, Stacking, Counting and Classification of Flexible Flat Food Products flat food products such as tortillas. The tortillas are interspersed between a pair of conveyor belts that move at the same speed to a discharge location between a pair of rollers, around which the respective conveyor belts extend. The speed of the tortillas causes them to be thrown from between the rollers towards a discharge tray. A counter determines when a predetermined number of tortillas have been downloaded into the discharge tray. The counter then operates an actuator to remove the tray from below the stack of tortillas, thus allowing them to fall on a discharge conveyor belt. The discharge conveyor belt then moves at an incremental distance. The tortillas that pass through the device are examined in order to detect the tortillas that are defective. When a defective tortilla is found, one of the rollers at the unloading location is deflected, thereby altering the trajectory of the tortillas that are thrown from the conveyor belts at the unloading location on a reject unloading conveyor belt. In Patent No. 5,601,397, entitled "Apparatus for Counting and Stacking Tortillas", invented by Manuel López and Rafael López, an apparatus having a series of conveyor belts for flattening and stacking a plurality of generally flat articles, flexible such as tortillas. The apparatus includes a first conveyor belt that extends along the first end, top, second end and bottom surfaces of a web support. The conveyor belt is adapted to move the flat items placed on the upper surface of the band holder from the first end to the second end. A second conveyor belt is deflected against the first web at the second end of the web support, to apply lateral and compressive forces to the flat items as they move along the second end of the web support. A third conveyor belt is located below the first and second conveyor belts, to receive the flat articles of the first belt, forming stacks thereof and then unloading the stacked flat articles. The motor installations handle the conveyor belts, first, second and third. In Patent Number 4,054,015, entitled "Packing Apparatus and Method", invented by Lorne A. Rowell, an apparatus for stacking food tablets in a cylindrical container. The random tablets are oriented in an alignment one after the other on an inclined conveyor that passes in an upward direction and are deposited in a straight cylindrical stacking tube, above a station for empty cylindrical containers. A valve comprising blades, lower and upper, operatively associated in the stacking tube loads the vertical piles of tablets in the cylindrical containers. In Patent Number 3,915,316, entitled "Counting and Stacking Apparatus", invented by Johnny B. Pomara, Jr.; an apparatus for counting and stacking substantially flat items, such as, in particular, food items of the nature of Mexican tortillas, which include a first feeder conveyor type band, a second stacking conveyor type band that meshes with a fork or stacking holder vertically movable and a separating conveyor. The articles are fed sequentially from a conventional conveyor of the apparatus such as an oven, to the feeder conveyor below a counting switch. Each article is discharged from the feed conveyor in a stacked relation towards the stacking conveyor against the stacking support. When the desired number of articles is stacked on the stacking conveyor against the support, the support retracts rapidly downwards, releasing the stack for discharge towards the separating conveyor. Between the discharge time of each stack and the arrival of the first article to form the next stack, the stacking support returns upwardly to the engagement relationship with the apportioning conveyor, to form and hold the next stack. The above-mentioned patented inventions differ from the present invention in that they fail to describe or claim at least a combination of the following characteristics represented in the present invention: container with container sleeve, vibrator, stacker, elevator, upper conveyor, lower conveyor, photoelectric eye and accountant. SUMMARY OF THE INVENTION This invention provides an improved tortilla stacker-countertop, wherein the tortillas are uniformly stacked and the stacks are transported to a bagging station, substantially ready for bagging. The present invention claims and describes novel elements such as, an elevator in sequence, an elevator, a stacker, a vibrator container and a conical container sleeve, which are an improvement of the material, making the invention more commercially viable.
The types of problems encountered in the prior art are the piles of tortillas that enter the inside sides of a container. In the prior art, unsuccessful attempts were made to solve this problem, specifically: no more smooth battery surfaces. However, the problem was solved by the present invention due to the vibrating container and the sleeve of the conical container. The innovations within the prior art are rapidly exploited in the field of automatic food preparation. The present invention was against the teachings of the art, which teach the semiautomatic processing of tortillas. The present invention solved a long felt need for a fully automated tortilla making apparatus. The present invention produced unexpected results specifically: the tortillas were damaged less and therefore had a lower loss rate. A synergistic effect occurred when using the present invention, due to the following facts and results of the experimentation: the cost of bagging was reduced because the tortillas were piled more evenly. Accordingly, it is an object of the present invention to provide a tortilla stacker-counter having a container, a vibrator, a stacker, an elevator, a top conveyor, a bottom conveyor, a photoelectric eye and a counter. In maintaining these objects and with others that will be apparent hereinafter, one aspect of the present invention resides, briefly stated, in the upper part of the container having an upper cover of the container, which has a left arrangement of the upper cover of the container and a right arrangement of the upper cover of the container. When the lower part of the container is designed in accordance with the present invention, it contains a lower extension of the container and a lower opening of the container. According to another aspect of the present invention the container side has a horizontal side slot of the container. Another feature of the present invention is that the vibrator has a vibrating arm. Still another feature of the present invention is that the stacker has a stacking cylinder, a mechanical stacker means and a stacker controller. Still another feature of the present invention is that the stacking cylinder has a piston of the cylindrical stacker, which has a piston plate of the stacking cylinder attached thereto. Still another feature of the present invention is that the stacking mechanical means has an entrance to the mechanical stacker means, an exit from the mechanical stacker means and a mechanical stacker means connector. Still another feature of the present invention is that the elevator has a lift cylinder, a lifting mechanical means, a first elevator controller, a second elevator controller, a third elevator controller and a vertical closing valve. Another feature of the present invention is that the upper conveyor has a superior conveyor belt. Still another feature of the present invention is that the lower conveyor has a lower conveyor belt, a lower conveyor belt and a lower conveyor belt, lower. The novel aspects that are considered characteristic for the invention are set forth in the appended claims. However, the invention by itself as well as for its construction as for its method of operation, together with advantages and additional objects thereof, will be better understood from the following description of the specific modalities when read and understood in relation to the invention. with the accompanying drawings.

Figure 2a is a schematic view of a tortilla stacker-counter (10), showing a piston of the elevator cylinder (18AA) with the piston plate of the stacking cylinder (16AAA) containing a first stack of tortillas (28A) in a retracting position and a piston of the stacking cylinder (16AA) in an extended position having an incoming tortilla (28C) that forms a second stack of tortillas (28B). Figure 2b is a schematic view of a tortilla stacker-counter (10), showing a piston of the elevator cylinder (18AA) with the piston plate of the stacking cylinder (16AAA) in a fully retracted position after the first tortilla stack (28A) was placed in the lower conveyor (22) and a piston of the stacking cylinder (16AA) in an extended position having an incoming tortilla (28C) that falls on the second stack of tortillas (28B). Figure 2c is a schematic view of a tortilla stacker-counter (10), showing a piston of the elevator cylinder (18AA) with the piston plate of the stacking cylinder (16AAA) in an extended position and the cylinder piston stacker (16AA) in an extended position having an incoming tortilla (28C) that falls into the second pile of tortillas (28B). Figure 2d is a schematic view of a tortilla stacker-counter (10), showing a piston of the elevator cylinder (18AA) with the piston plate of the stacking cylinder (16AAA) in an incremental retraction position and the piston of the stacking cylinder (16AA) in a retracted position that places the second stack (28B) on top of the stacker cylinder piston plate (16AAA). Figure 3 is a perspective view of a tortilla stacker-counter (10), constructed in accordance with the invention. DESCRIPTION OF THE PREFERRED MODALITY Referring initially to figure 1, the novel elements of our stacker-counters are the conical container (12), the piston of the elevator cylinder (18AA) and the piston of the stacking cylinder (16AA). For example, for corn tortillas from 6.0 to 6,125 inches in diameter, the container (12) is 5.0 inches tall and has a frustoconical inner sleeve (12A) that has a diameter of 6.5 inches at the top and 6.25 inches at the bottom. A pneumatic eccentric vibrator (14) is provided to "jiggle" any misalignment of the tortillas that might otherwise have a tendency to stick, bend, or get stuck in the container. The piston plate of the stacking cylinder (16AAA) extends through a lateral slot of the container (12CA) on the side of the container (12). The piston plate of the stacking cylinder (16AAA) is a thin sheet-like member with parallel linear sides and a rounded end complementary to the radius of the container sleeve (12A). The piston plate of the stacker cylinder (16AAA) is sized slightly smaller than the diameter of the inner container sleeve (12A) in the lateral slot of the container (12CA). The stacker (16) and the elevator (18) are pneumatically driven in a precise sequence, as will be described below in relation to Figures 2a-2d. The remaining elements in figure 1, are pieces of conventional tortilla cooking equipment, familiar to those skilled in the art such as, the photoelectric eye (24), the upper conveyor (20), the lower conveyor (22), the vertical shut-off valve (18F), the stacker controller (16C), the first elevator controller (18C), the second elevator controller (18D) and the third elevator controller (18E), which are basically timers, relatives for those experts in the field. In Figure 2a, a finished tortilla stack, the first tortilla stack (28A), has a preselected number of tortillas, all in a stack with uniform sides, ready for bagging. The first tortilla stack (28A) is lowered into the elevator cylinder piston plate (18AAA) attached to the elevator cylinder piston (18AA) to the lower conveyor (22). The lower conveyor (22) ends at a bagging station. Meanwhile the stacker cylinder piston (16AA) has been extended to its fully extended position, where the piston plate of the elevator cylinder (18AAA) serves to receive the constant flow of incoming tortillas (28C), while the piston of the elevator cylinder (18AA) is ordered in series. The flow of the incoming tortilla (28C) is never interrupted. The elevator sequence starts when the first pile of tortillas (28A) is completed, that is, it has the required number of units as determined by the photoelectric eye (24) and the counter (26). While the elevator cylinder piston (18AA) is ordered in series, the elevator cylinder piston plate (18AAA) serves as a temporary floor for the construction of a new second stack of tortillas (28B). In Figure 2b, the piston plate of the elevator cylinder (18AAA) has descended to a position where the first stack of tortillas (28A) has been transferred to the lower conveyor (22). Meanwhile, the new second tortilla stack (28B) continues to be built into the piston of the stacking cylinder (16AA). In Figure 2c, the piston of the elevator cylinder (18AA) continues its sequence as it passes upwards. Meanwhile, the new second tortilla stack (28B) continues to be built into the piston plate of the elevator cylinder (18AAA). Finally, in Figure 2d, the lift cylinder piston (18AA) has returned to the position shown in Figure 1, where the lift cylinder piston plate (18AAA) again serves as the floor for the second second. stack of tortillas (28B). The piston of the stacking cylinder (16AA) has been retracted. To maintain a relatively constant elevation of the upper portion of the second tortilla stack (28B), the elevator release valve (18F) is intermittently operated to lower the elevator cylinder piston (18AA) in relatively small amounts, as shown in FIG. illustrated schematically by the arrows (30). When the second stack of tortillas (28B) reaches its predetermined number of units, the sequence is repeated, wherein the piston of the elevator cylinder (18AA) with the piston plate of the elevator cylinder (18AAA) is lowered and the piston of the Stacking cylinder (16AA) with the piston plate of the stacking cylinder (16AAA) extends, as shown in figure 2a. Referring now to Figure 3 in conjunction with the other figures, the tortilla stacker-counter (10) has a container (12), which includes an upper part of the container (12T), a lower part of the container (12B) and one side of the container (12C) having a lateral horizontal slot of the container (12CA) placed therein. A stacker (16) is positioned adjacent to the container (12) and the stacker (16) comprises a stacking cylinder (16A) having a piston of the movable stacking cylinder (16AA) attached at a front distal end to a rear distal end of a horizontal piston plate of the stacking cylinder (16AAA) which is inserted and retracted through the lateral slot of the container (12CA).
The stacker (16) also includes a mechanical stacker (16B) The mechanical stacker means (16B) includes an inlet to the stacking mechanical means (16BA) and an output of the stacking mechanical means (16BB) attached to, and in communication with the lower and upper ends, respectively, of the stacking cylinder (16A). The mechanical stacker means (16B) further includes a mechanical stacker means connector (16BC), which is actuated by pneumatic or hydraulic means. The mechanical stacker means (16B) is connected to, and controlled by, a stacker controller (16C). An elevator (18) is placed directly below the container (12). The lifter (18) includes an elevator cylinder (18A) having a piston of the elevator cylinder (18AA) movably positioned therein. The elevator cylinder piston (18AA) includes a horizontal plate of the elevator cylinder piston (18AAA) securely attached to an upper distal end thereof. The lifter (18) further includes a mechanical lifting means (18B). Lifting mechanical means (18B) includes an entry of the mechanical lifting means (18BA) having a vertical shut-off valve (18F) and an output of the lifting mechanical means (18BB) attached to, and in communication with, the lower and upper ends, respectively, of the elevator cylinder (18A). The lifting mechanical means (18B) further includes a connector of the lifting mechanical means (18BC), which is operated by hydraulic or pneumatic means. The lifting mechanical means (18B) is connected to and controlled by a second elevator controller (18D), which is electrically connected to a first elevator controller (18C) which is electrically connected to the stacker controller (16C). The lifting mechanical means (18B) further includes a third elevator controller (18E) attached thereto. The vertical shut-off valve (18F) is electrically connected to the first elevator controller (18C). An upper conveyor (20) is placed horizontally in alignment with the upper part of the container (12T). The upper conveyor (20) includes a rotatable upper conveyor belt (20A), into which the incoming tortillas (28C) are placed. A lower conveyor (22) is placed between the elevator (18) and the container (12). The lower conveyor (22) includes a lower conveyor left belt (22AL) and a lower conveyor right belt (22AR) rotated synchronously. The space between the lower conveyor left belt (22AL) and the lower conveyor right belt (22AR) is slightly larger than the diameter of the elevator cylinder piston plate (18AAA), which deposits a first stack of tortillas (28A) ) on the lower conveyor belt (22AL) and one on the lower conveyor belt (22AR). - A photoelectric eye (24) is electrically connected to the third elevator controller (18E) and a counter (26) is electrically connected to the photoelectric eye (24). The container (12) further includes a container sleeve (12A) securely mounted therein and the container sleeve (12A) includes a diameter slightly larger than a diameter of an incoming tortilla (28C). The upper part of the container (12T) further includes an upper container cover (12TA) having an opening in front of the upper conveyor (twenty). The upper cover of the container (12TA) works to facilitate the addressing of the incoming tortilla (28C) towards the container (12), which rests on the piston plate of the elevator cylinder (18AAA) forming a second stack of tortillas (28B). The upper cover of the container (12TA) includes a left disposition of the upper cover of the container (12TAL) and a right disposition of the upper cover of the container (12TAR) placed at opposite ends. The left disposition of the upper cover of the container (12TAL) and the right disposition of the upper cover of the container (12TAR) work to facilitate the addressing of the incoming tortilla (28C) towards the container (12). The lower part of the container (12B) includes an extension of the lower part of the container (12BA) placed on a side opposite the movable direction of the lower conveyor (22). The lower extension of the container (12BA) functions to facilitate the addressing of the first stack of tortillas (28A) on the left lower carrier band (22AL) and to the lower right carrier band (22AR). The lower part of the container (12B) further includes a lower container opening (12BB) extending upwardly therefrom. The opening in the lower part of the container (12BB) functions to facilitate the addressing of the first stack of tortillas (28A) on the lower conveyor left belt (22AL) and the lower conveyor right belt (22AR). A vibrator (14) is attached to the side of the container (12C) by means of a vibrating arm (14A). The vibrator (14) functions to jiggle the container (12) by directing the incoming tortilla (28C) to the appropriate position at the top of the second pile of tortillas (28B). The container sleeve (12A) includes a conical configuration tapering towards a lower portion thereof.
