CORTADOR SUPERIOR DE LA CORTEZA DE CÍTRICOS  SUPERIOR CUTTERS OF THE CITRUS COURT
PARA EXTRACTOR DE ZUMOS Y CONJUNTO FORMADO POR CORTADORFOR JUICE EXTRACTOR AND ASSEMBLY FORMED BY CUTTER
SUPERIOR Y CORTADOR INFERIOR CAMPO DE LA INVENCIÓN TOP AND LOWER CUTTER FIELD OF THE INVENTION
La presente invención se refiere a un cortador superior de la corteza de cítricos y a un conjunto formado por un cortador superior y un cortador inferior, de especial aplicación en extractores de zumos de cítricos. The present invention relates to an upper cutter of citrus bark and a set consisting of an upper cutter and a lower cutter, of special application in citrus juice extractors.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
El procedimiento conocido para la extracción de zumos de frutas, especialmente cítricos, consiste en la introducción de la fruta en una máquina que cumple dicha función (extractor de zumos). Para ello, se canalizan y empujan las frutas mediante unas horquillas a unas copas inferiores que reciben el fruto cuando las copas superiores se encuentran en su punto más alto, permitiendo que el fruto se aloje en el fondo de las copas inferiores. Este posicionamiento en las copas inferiores se realiza por mediación de ejes giratorios que están sincronizados con la posición de las copas superiores. The known procedure for the extraction of fruit juices, especially citrus fruits, consists in the introduction of the fruit into a machine that fulfills this function (juice extractor). To do this, the fruits are channeled and pushed by means of forks to lower cups that receive the fruit when the upper cups are at their highest point, allowing the fruit to lodge at the bottom of the lower cups. This positioning in the lower cups is performed by means of rotating shafts that are synchronized with the position of the upper cups.
A continuación, dos cortadores (uno superior y otro inferior) practican una incisión circular, en forma de taco o disco, en la parte superior e inferior de la fruta respectivamente, para permitir la salida del zumo a través del tubo filtro, situado inferiormente a las copas, hacia un colector de zumos cuando las copas superior e inferior comprimen la fruta.  Next, two cutters (one upper and one lower) make a circular incision, in the form of a block or disk, in the upper and lower part of the fruit respectively, to allow the juice to exit through the filter tube, located inferiorly to the glasses, towards a juice collector when the upper and lower glasses compress the fruit.
En el estado habitual de la técnica, en el que el cortador superior desciende hasta alcanzar a ía cuchilla inferior, y en dicho proceso el filo de dicha cuchilla superior acaba acoplándose exteriormente al fiio del cortador inferior durante el corte, se produce una pérdida parcial de rendimiento en jugo, ya que no existe un cierre perfectamente hermético entre ambos cortadores superior e inferior. SUMARIO DE LA INVENCIÓN In the usual state of the art, in which the upper cutter descends until it reaches the lower blade, and in said process the edge of said upper blade ends up engaging externally to the fixture of the lower cutter during cutting, a partial loss of juice yield, since there is no perfectly tight seal between both upper and lower cutters. SUMMARY OF THE INVENTION
Así, el objeto de la presente invención es proporcionar un cortador superior de la corteza de cítricos para extractor de zumos que permita un acoplamiento o cierre más estanco al realizar la incisión superior en el cítrico. Thus, the object of the present invention is to provide a superior citrus rind cutter for juice extractor that allows a more tight coupling or closure when making the upper incision in the citrus.
La invención proporciona un cortador superior de la corteza de cítricos para extractor de zumos, de los utilizados en máquinas de alimentación de la fruta por cintas que las alinean y las separan para su posterior tratamiento individualizado entre dos copas, una copa superior y una copa inferior, donde dos cortadores, uno superior y otro inferior comprenden sendos bordes cortantes que producen sendas incisiones superior e inferior en la fruta para permitir la salida dei zumo, comprendiendo además el cortador superior un vástago cilindrico. Dicho cortador superior está fabricado sin salidas laterales y de manera que el diámetro exterior de su extremo inferior le permite acoplarse interiormente al cortador inferior, y comprende adicionalmente un tramo troncocónico intermedio a continuación de su extremo inferior que al penetrar en el cortador inferior produce un cierre estanco entre ambos cortadores superior e inferior.  The invention provides an upper cutter of citrus rind for juice extractor, of those used in fruit feeding machines by bands that line and separate them for subsequent individualized treatment between two cups, a top cup and a bottom cup , where two cutters, one upper and one lower comprise two cutting edges that produce upper and lower incisions in the fruit to allow the juice to exit, the upper cutter also comprising a cylindrical rod. Said upper cutter is manufactured without side outlets and so that the outer diameter of its lower end allows it to be internally coupled to the lower cutter, and additionally comprises an intermediate truncated conical section following its lower end which when penetrating the lower cutter produces a closure waterproof between both upper and lower cutters.
La invención también proporciona un conjunto formado por cortador superior y cortador inferior, caracterizado porque comprende un cortador superior con las anteriores características y un cortador inferior con un borde cortante, que dispone en su parte superior interna de una entrada troncocónica a modo de rebaje, convergente hacia abajo, y de igual conicidad que la del tramo troncocónico del cortador superior.  The invention also provides an assembly formed by upper cutter and lower cutter, characterized in that it comprises an upper cutter with the above characteristics and a lower cutter with a cutting edge, which has in its inner upper part a conical, concave recessed, inwardly shaped inlet. down, and of equal conicity than that of the conical section of the upper cutter.
Mediante esta configuración geométrica con ausencia de salidas laterales y un diámetro exterior adecuado de! extremo inferior del cortador superior se produce un cierre total entre el núcleo del cortador superior y la cara interna del cortador inferior, y se consigue la máxima proporción posible de rendimiento en jugo.  Through this geometric configuration with absence of lateral outlets and an adequate outside diameter of! lower end of the upper cutter produces a total closure between the core of the upper cutter and the inner face of the lower cutter, and the maximum possible proportion of juice yield is achieved.
Otra ventaja de la invención es que, al poder ser el cortador superior una pieza enteriza, se logra una mayor rigidez y robustez, evitando con ello gran parte de las sustituciones de esta pieza por desgastes o roturas. Otras características y ventajas de la presente invención se desprenderán de ia descripción detallada que sigue de una realización ilustrativa de su objeto en relación con las figuras que se acompañan, Another advantage of the invention is that, since the upper cutter can be an integral piece, greater rigidity and robustness are achieved, thereby avoiding much of the substitutions of this piece for wear or breakage.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION
En las figuras 1 a 4 se representan diversas vistas del cortador superior 1 de la corteza de cítricos para extractor de zumos de la invención. Various views of the upper cutter 1 of the citrus rind for juice extractor of the invention are shown in Figures 1 to 4.
Se observa que dicho cortador superior 1 tiene forma de cuerpo de revolución y que presenta un vástago cilindrico 4 en su parte superior y zonas más anchas de diámetros diferenciados en su parte inferior. En concreto, en la parte inferior hay un tramo ensanchado 10 y un extremo inferior 5, unidos por un tramo troncocónico 1 1 intermedio.  It is observed that said upper cutter 1 has the shape of a revolution body and that it has a cylindrical rod 4 in its upper part and wider areas of different diameters in its lower part. Specifically, in the lower part there is a widened section 10 and a lower end 5, connected by an intermediate trunk section 1 1.
El borde de su extremo inferior 5 constituye un borde cortante 13, que será el que incida sobre la parte superior de la fruta cuando comience el proceso de extracción del zumo.  The edge of its lower end 5 constitutes a cutting edge 13, which will be the one that hits the top of the fruit when the juice extraction process begins.
Como se representa en dichas figuras, el cortador superior 1 está fabricado sin salidas laterales. Por otro lado, el diámetro exterior de su extremo inferior 5 le permite acoplarse al cortador inferior 2 representado en las figuras 5 a 7, penetrando en él para producir un cierre estanco entre ambos cortadores superior 1 e inferior 2.  As shown in said figures, the upper cutter 1 is manufactured without side outlets. On the other hand, the outer diameter of its lower end 5 allows it to be coupled to the lower cutter 2 shown in Figures 5 to 7, penetrating it to produce a tight seal between both upper 1 and lower 2 cutters.
La representación del conjunto acoplado formado por el cortador superior 1 y el cortador inferior 2 se puede apreciar en las figuras 8 y 9.  The representation of the coupled assembly formed by the upper cutter 1 and the lower cutter 2 can be seen in Figures 8 and 9.
El cortador superior 1 puede estar fabricado como pieza enteriza, es decir, en una única pieza evitando soldaduras de diferentes elementos.  The upper cutter 1 can be manufactured as an integral piece, that is, in a single piece avoiding welding of different elements.
Asimismo, el vástago cilindrico 4 del cortador superior 1 preferentemente presentará un rebaje pertmetral 6 practicado sobre él.  Also, the cylindrical rod 4 of the upper cutter 1 will preferably have a pertmetral recess 6 made thereon.
En las figuras 5 a 7 se representan diversas vistas del cortador inferior 2 de la corteza de cítricos para extractor de zumos que actúa conjuntamente con el cortador superior 1 de las figuras 1 a 4.  Various views of the lower cutter 2 of the citrus rind for juice extractor acting in conjunction with the upper cutter 1 of Figures 1 to 4 are shown in Figures 5 to 7.
Se observa que dicho cortador inferior 2 tiene forma de cuerpo de revolución interiormente hueco, con zonas de diámetros diferenciados. Eí borde de su extremo superior constituye un borde cortante 14, que será el que incida sobre la parte inferior de la fruta cuando comience el proceso de extracción del zumo. It is noted that said lower cutter 2 is in the shape of an internally hollow revolution body, with zones of different diameters. The edge of its upper end constitutes a cutting edge 14, which will be the one that strikes on the bottom of the fruit when the juice extraction process begins.
El cortador inferior 2 dispone en su parte superior interna de una entrada troncocónica 12 a modo de rebaje, convergente hacia abajo, y con la misma conicidad que la del tramo troncocónico 1 1 del cortador superior .  The lower cutter 2 has in its inner upper part a truncated conical entry 12 as a recess, convergent downwards, and with the same conicity as that of the truncated conical section 1 1 of the upper cutter.
En la figura 10 se representa una sección parcial del conjunto formado por el eje 9, el cortador superior 1 y ¡á copa superior 3 en el portacopas 7 correspondiente. Se observa que el cortador superior 1 puede estar sujeto al portacopas 7 mediante un medio de fijación 8 (por ejemplo, tomillo lateral, fijador, pasador o medios similares) gracias a un orificio practicado en el portacopas 7 en coincidencia con dicho rebaje perimetral 6. De este modo se evita tener que desmontar el portacopas 7 para la sustitución del cortador superior 1 y el consiguiente desajuste de cada eje portacopas.  Figure 10 shows a partial section of the assembly formed by the axis 9, the upper cutter 1 and the upper cup 3 in the corresponding cup holder 7. It is noted that the upper cutter 1 can be attached to the cup holder 7 by means of a fixing means 8 (for example, lateral thyme, fixing, pin or similar means) thanks to a hole made in the cup holder 7 in coincidence with said perimeter recess 6. This avoids having to disassemble the cup holder 7 for the replacement of the upper cutter 1 and the subsequent mismatch of each cup holder shaft.
La figura 1 1 representa la vista en perspectiva del conjunto de la figura 10.  Figure 1 1 represents the perspective view of the assembly of Figure 10.
Como se observa en las figuras 1 a 4, el cortador superior 1 se ha fabricado en una única pieza sin necesidad de tener una cuchilla exterior con salidas laterales soldada al núcleo. De esta manera, cuando el cortador superior 1 desciende hasta alcanzar al cortador inferior 2, el extremo inferior 5 del cortador superior 1 penetra en el hueco del cortador inferior 2, y el tramo troncocónico 1 1 del cortador superior 1 se asienta sobre la pared interna de la entrada troncocónica 12 del cortador inferior 2, produciéndose un cierre total entre dicho tramo del cortador superior 1 y la cara interna del hueco del cortador inferior 2, como se puede observar en las figuras 8 y 9. De esta manera se logra un cierre totalmente estanco y se evita cualquier posible pérdida de jugo por las salidas laterales, como sucede en otras configuraciones existentes en ei mercado, permitiendo obtener en cada ciclo de trabajo, es decir, en cada corte de una nueva fruta, el máximo rendimiento en jugo.  As can be seen in figures 1 to 4, the upper cutter 1 has been manufactured in a single piece without the need of having an outer blade with lateral outlets welded to the core. Thus, when the upper cutter 1 descends until it reaches the lower cutter 2, the lower end 5 of the upper cutter 1 penetrates the hollow of the lower cutter 2, and the frustoconical section 1 1 of the upper cutter 1 sits on the inner wall of the frustoconical inlet 12 of the lower cutter 2, producing a total closure between said section of the upper cutter 1 and the inner face of the hollow of the lower cutter 2, as can be seen in Figures 8 and 9. In this way a closure is achieved totally tight and any possible loss of juice is avoided by the lateral outlets, as in other configurations existing in the market, allowing to obtain in each cut of work, that is to say, in each cut of a new fruit, the maximum yield in juice.
La entrada troncocónica 12 del cortador inferior 2 facilita el guiado del cortador superior 1 dentro del cortador inferior 2 sin que se dañe el filo de su borde cortante 3 por una posible ausencia de alineación entre los centros de ambos bordes cortantes 13, 14, además de lograr un cierre más hermético. La inclinación o conicidad del tramo troncocónico 11 del cortador superior 1 debe ser igual a la de la entrada troncocónica 12 del cortador inferior 2, de tal modo que consiguen un cierre estanco al juntarse ambas durante la etapa correspondiente del proceso de extracción de zumo. The frustoconical entry 12 of the lower cutter 2 facilitates the guidance of the upper cutter 1 within the lower cutter 2 without damaging the edge of its cutting edge 3 by a possible lack of alignment between the centers of both cutting edges 13, 14, in addition to achieve a more tight seal. The inclination or conicity of the frustoconical section 11 of the upper cutter 1 must be equal to that of the frustoconical entry 12 of the lower cutter 2, such that they achieve a tight seal when both are joined during the corresponding stage of the juice extraction process.
El riesgo de rotura o niveles de desgaste de dicho cortador superior 1 desciende al mínimo posible debido al diseño geométrico y al estudio dinámico de la pieza, pues está constituido por un único elemento, evitando soldaduras, que son puntos de debilitamiento de cara a una posible rotura.  The risk of breakage or wear levels of said upper cutter 1 falls to the minimum possible due to the geometric design and the dynamic study of the piece, since it is constituted by a single element, avoiding welds, which are weakening points facing a possible break.
Para lograr una robustez adecuada, el vástago cilindrico 4 puede fabricarse de un diámetro de alrededor de 12 mm en su parte no rebajada.  To achieve adequate robustness, the cylindrical rod 4 can be manufactured with a diameter of about 12 mm in its non-recessed part.
En las realizaciones preferentes de la invención que acabamos de describir pueden introducirse aquellas modificaciones comprendidas dentro del alcance definido por las reivindicaciones siguientes.  In the preferred embodiments of the invention just described, those modifications within the scope defined by the following claims can be introduced.
