In addition, the central wheel (3) and the delimiting wheels (4, 5) are alternately coupled to one another, such that the limiting wheels (4, 5) and the main shaft (2) can rotate in the same rotation direction or in opposite directions.

Description

MECANISMO DE ENGRANAJES PARA CONVERSIÓN DE GIRO  GEAR MECHANISM FOR CONVERSION OF TURN
DESCRIPCIÓN El objeto de la presente invención es un mecanismo de engranajes que está configurado para la conversión del doble sentido de giro de un eje en un único sentido de giro de otros ejes solidarios con el mismo. Es decir, que a partir de la rotación de un primer eje, e independientemente de su sentido de giro, se fuerce a, al menos un eje solidario y adicional a que rote siempre en el mismo sentido de giro. DESCRIPTION The object of the present invention is a gear mechanism that is configured for the conversion of the double direction of rotation of an axis in a single direction of rotation of other axes integral with it. That is, from the rotation of a first axis, and regardless of its direction of rotation, at least one integral and additional axis is forced to always rotate in the same direction of rotation.
Uno de los múltiples usos, no limitativos, de la presente invención es el de la construcción de utensilios de limpieza totalmente mecánicos para la recolección de pequeños objetos como, por ejemplo, un recogemigas o una escoba de rodillos. Estado de la técnica anterior One of the many non-limiting uses of the present invention is the construction of fully mechanical cleaning utensils for the collection of small objects such as a crumb or roller broom. Prior art
El estado de la técnica anterior de los mecanismos de engranajes para la conversión de giro es fácilmente explicable partiendo de uno de los usos no limitativos de dicho mecanismo, tal y como son los recogemigas. Estos dispositivos son utensilios que se emplean para la recogida de las migas de pan y los pequeños residuos de las mesas para la limpieza de las mismas. Actualmente existen distintos tipos de recogemigas mecánicos, como son los de tipo paleta (como el descrito en el modelo de utilidad español con número de solicitud U8600519) o por rodillos (por ejemplo, el U0134678). Dichos recogemigas por rodillos se basan en disponer, como mínimo de un rodillo con filamentos que, al girar sobre el eje longitudinal que atraviesa el recogemigas, realiza el barrido de las migas de pan hacia el interior del mismo. The prior art of the gear mechanisms for the conversion of rotation is easily explained starting from one of the non-limiting uses of said mechanism, such as the crumbs. These devices are utensils that are used to collect bread crumbs and small debris from the tables to clean them. Currently there are different types of mechanical crumbs, such as the pallet type (as described in the Spanish utility model with application number U8600519) or by rollers (for example, U0134678). Said crumbs by rollers are based on having, at least one roller with filaments that, when turning on the longitudinal axis that crosses the crumb, makes the sweeping of the bread crumbs into the same.
En este tipo de mecanismos, el sentido de giro del rodillo de filamentos depende del sentido del uso longitudinal del recogemigas por encima de la mesa, de forma que el sentido de giro se alterna de sentido horario a sentido contrario al de las agujas del reloj, en función de que el recogemigas se desplace longitudinalmente por encima de la mesa de izquierda a derecha o viceversa, respectivamente. Explicación de la invención In this type of mechanism, the direction of rotation of the filament roller depends on the direction of longitudinal use of the crumb over the table, so that the direction of rotation alternates clockwise counterclockwise, depending on the crumbs moving longitudinally above the table from left to right or vice versa, respectively. Explanation of the invention.
Para paliar los problemas técnicos arriba mencionados, se presenta el mecanismo de engranajes para la conversión de giro, el cual consiste en un mecanismo que mantiene el sentido de giro de dos rodillos externos, para el caso de los dispositivos recogemigas, en donde uno de dichos rodillos girará siempre en sentido horario, mientras que el otro girará siempre en sentido contra-horario, independientemente del sentido de uso longitudinal del conjunto del dispositivo. To alleviate the technical problems mentioned above, the mechanism of gears for the conversion of rotation, which consists of a mechanism that maintains the direction of rotation of two external rollers, in the case of the pick-up devices, where one of said rollers will always turn clockwise, while the other will always turn counter-clockwise, regardless of the sense of longitudinal use of the device as a whole.
El eje principal tiene una porción de su eje no cilindrica, en una realización particular de la invención es ovalada, y sobre esta parte del cilindro se sitúa una pieza acoplada que gira en el mismo sentido de giro del eje principal, y que es susceptible de desplazarse longitudinalmente sobre el eje. The main axis has a portion of its non-cylindrical axis, in a particular embodiment of the invention it is oval, and on this part of the cylinder a coupled part is placed which rotates in the same direction of rotation of the main axis, and which is capable of move longitudinally on the axis.
Esta pieza acoplada consiste en una rueda central que dispone, colocadas en la superficie de ambas caras, una o varias coronas de dientes centradas en el eje de dicha rueda y donde cada corona está formada por, al menos, un diente. Esta rueda está delimitada en ambas caras por otras dos ruedas delimitadoras dentadas, las cuales están montadas sobre la porción cilindrica del eje, y donde además estas ruedas delimitadoras giran libremente sobre el citado eje, pudiendo por tanto girar el eje y cada una de las ruedas delimitadoras en sentidos de giros opuestos. Cada una de las citadas dos ruedas delimitadoras comprenden, además, una o varias coronas de dientes concéntricas respecto de su propio eje, y donde cada corona puede estar formada por uno o varios dientes, estando además colocadas sobre la superficie de la cara que da a la rueda central con coronas dentadas en ambas superficies, de tal forma que las coronas de la rueda central, junto con las coronas de las otras dos ruedas que la delimitan engranen entre sí perfectamente. This coupled piece consists of a central wheel that disposes, placed on the surface of both sides, one or more crowns of teeth centered on the axis of said wheel and where each crown is formed by at least one tooth. This wheel is delimited on both sides by two other sprocket delimiters, which are mounted on the cylindrical portion of the axle, and where also these delimiter wheels rotate freely on the aforementioned axle, thus being able to rotate the axle and each of the wheels delimiters in opposite directions. Each of the said two delimiting wheels further comprises one or more crowns of concentric teeth with respect to its own axis, and where each crown can be formed by one or more teeth, being also placed on the surface of the face that gives the central wheel with toothed crowns on both surfaces, in such a way that the crowns of the central wheel, together with the crowns of the other two wheels that delimit it, engage each other perfectly.
Así pues, cuando el eje principal está girando en un determinado sentido de giro, la rueda central, que gira en el mismo sentido de giro que el eje principal, está acoplada con una de las ruedas delimitadoras, girando ambas en el mismo sentido. Thus, when the main axis is rotating in a certain direction of rotation, the central wheel, which rotates in the same direction of rotation as the main axis, is coupled with one of the delimiting wheels, both turning in the same direction.
Cada vez que el eje principal cambia de sentido, provoca que la rueda central y la rueda delimitadora con la que está acoplada se desacoplen por la forma de los dientes de las coronas acopladas, provocando que la rueda central se desplace longitudinalmente sobre el eje, se acople con la otra rueda delimitadora y giren ambas en el mismo sentido de giro. De esta forma, cada rueda delimitadora gira en un único sentido de giro y, solidariamente, mediante las ruedas dentadas adicionales acopladas a las mismas, se consigue que los ejes adicionales giren igualmente en un único sentido de giro. Las cuatro superficies que contienen las coronas pueden contener una o varias coronas centradas en el eje de las ruedas y con un diente como mínimo en cada una de las coronas. La cantidad de coronas y dientes afecta al tiempo de reacción del conjunto en acoplar la rueda central a una determinada rueda delimitadora y desacoplarla para acoplarla en la otra. Each time the main axle changes direction, it causes the center wheel and the bounding wheel with which it is coupled to be disengaged by the shape of the teeth of the coupled crowns, causing the central wheel to move longitudinally on the axle, couple with the other bounding wheel and turn both in the same direction of rotation. In this way, each delimiter wheel rotates in a single direction of rotation and, in solidarity, by means of the additional cogwheels coupled to them, it is achieved that the additional axles also rotate in a single direction of rotation. The four surfaces that contain the crowns may contain one or more crowns centered on the axle of the wheels and with a tooth at least in each of the crowns. The amount of crowns and teeth affects the reaction time of the assembly in coupling the central wheel to a certain bounding wheel and decoupling it to couple it in the other.
Asimismo los dientes que componen las coronas pueden tener múltiples formas, afectando dicha forma a la facilidad con que la rueda central se desacopla y acopla en las ruedas delimitadoras al cambiar de sentido de giro. Likewise, the teeth that make up the crowns can have multiple shapes, this shape affecting the ease with which the central wheel is disengaged and engages in the bounding wheels when changing the direction of rotation.
La principal ventaja de la invención es, por tanto, mantener el sentido de giro de los rodillos, de forma que, al estar situados uno al lado del otro, uno gire en sentido horario y el otro gire en sentido anti-horario, de tal forma que ambos rodillos producen un efecto de barrido (en el ejemplo de la aplicación, un barrido de las migas) hacia el interior de los mismos, evitando que, al cambiar el sentido de uso longitudinal del dispositivo, es decir, del eje principal, las partículas pasen a ser expulsadas hacia el exterior. De esta forma, los elementos externos siempre son barridos hacia el interior de los rodillos, aumentando la eficacia del dispositivo y permitiendo realizar en el interior del dispositivo un peinado de los rodillos para extraer las partículas enganchadas y depositarlas en un contenedor de partículas, el cual queda fuera del objeto de la presente invención. The main advantage of the invention is, therefore, to maintain the direction of rotation of the rollers, so that, being located next to each other, one rotates clockwise and the other rotates counterclockwise, such so that both rollers produce a sweeping effect (in the example of the application, a sweeping of the crumbs) towards the inside thereof, preventing that, by changing the direction of longitudinal use of the device, that is, of the main axis, the particles become expelled outwards. In this way, the external elements are always swept into the rollers, increasing the effectiveness of the device and allowing the inside of the device to make a comb of the rollers to extract the hooked particles and deposit them in a particle container, which is outside the object of the present invention.

Exposición detallada de un modo de realización. Detailed exposition of an embodiment.
Como es posible observar en la FIG.1 , el mecanismo de engranajes objeto de la presente invención, en un ejemplo de aplicación particular no limitativo como recogedor de migas, comprende una primera rueda (1 ) o rueda del recogemigas, la cual está en contacto permanente con la superficie objeto de la limpieza, de tal forma que al desplazar el dispositivo horizontalmente hacia la izquierda, dicha primera rueda (1 ) se desplazará en sentido contrario al de las agujas del reloj, mientras que si desplazamos el dispositivo horizontalmente hacia la derecha, la citada primera rueda (1 ) girará en sentido horario. Esta primera rueda (1 ) está solidariamente unida a un eje principal (2), de tal forma que dicho eje (2) y dicha rueda (1 ) giran en el mismo sentido. As it is possible to observe in FIG. 1, the gear mechanism object of the present invention, in an example of a particular non-limiting application as a crumb picker, comprises a first wheel (1) or wheel of the crumb, which is in contact permanent with the surface object of cleaning, so that when moving the device horizontally to the left, said first wheel (1) will move counterclockwise, while if we move the device horizontally to the right , said first wheel (1) will turn clockwise. This first wheel (1) is integral to a main axle (2), so that said axle (2) and said wheel (1) rotate in the same direction.
Tal y como se aprecia en la FIG.2, el eje principal (2) es cilindrico excepto en una porción (21 ) del mismo, en donde su sección es preferentemente ovalada en el presente ejemplo de realización práctica. Es sobre esta porción ovalada (21 ) donde se sitúa una rueda central (3), acoplada a dicha porción ovalada (21 ), desplazable sobre la misma, y girando solidariamente con el citado eje principal (2), tal y como es posible observar en la FIG.3. La rueda central (3) consiste, esencialmente, en una rueda con un eje no cilindrico (31 ), en esta realización práctica de sección ovalada, y que comprende, en ambas superficies de sus caras, una corona dentada (32,33) concéntricas respecto del eje de la rueda (31 ), tal y como se puede apreciar en la FIG.4. As can be seen in FIG. 2, the main shaft (2) is cylindrical except in a portion (21) thereof, where its section is preferably oval in the present example of practical embodiment. It is on this oval portion (21) where a central wheel (3) is placed, coupled to said oval portion (21), movable on it, and rotating in solidarity with said main axis (2), as it is possible to observe in FIG. 3. The central wheel (3) consists essentially of a wheel with a non-cylindrical axle (31), in this practical embodiment of oval section, and comprising, on both surfaces of its faces, a concentric toothed crown (32,33) with respect to the wheel axle (31), as can be seen in FIG. 4.
La rueda central (3) está a su vez delimitada por una primera y una segunda rueda dentada (4,5) o ruedas delimitadoras montadas sobre el mismo eje principal (2) pero sobre su porción cilindrica, girando libremente sobre el citado eje principal (2), de forma que cada una de las ruedas delimitadoras (4,5) y el citado eje principal (2) puedan girar en un mismo sentido de giro o en sentidos opuestos. The central wheel (3) is in turn delimited by a first and a second cogwheel (4,5) or bounding wheels mounted on the same main axis (2) but on its cylindrical portion, freely rotating on said main axis ( 2), so that each of the bounding wheels (4,5) and said main shaft (2) can rotate in the same direction of rotation or in opposite directions.
Cada rueda delimitadora (4,5) comprende, a su vez, una corona dentada (41 ,51 ) adicional concéntrica respecto de sus respectivos ejes (42,52) de las ruedas delimitadoras y colocadas sobre la superficie de la cara enfrentada a la rueda principal (3), de tal forma que las coronas (32,33) de la rueda central (3) engranen, respectivamente, con las coronas (41 ,51 ) de ambas ruedas delimitadoras (4,5), tal y como se aprecia en la FIG.7. Each bounding wheel (4,5) comprises, in turn, an additional concentric toothed crown (41, 51) with respect to their respective axes (42,52) of the bounding wheels and placed on the surface of the face facing the wheel main (3), so that the crowns (32.33) of the central wheel (3) engage, respectively, with the crowns (41, 51) of both bounding wheels (4,5), as can be seen in FIG. 7.
Los dientes (32a,33a,41 a,51 a) de las coronas (32,33,41 ,51 ) respectivamente son prismas triangulares con una sección en forma de triángulo rectángulo. Estos prismas se sitúan sobre la superficie de las ruedas respectivas (3,4,5) apoyados sobre, al menos, uno de los catetos del triángulo rectángulo de la sección. Para conseguir un acople perfecto, es necesario que una de las bases, la más próxima al eje de la rueda, tenga un cateto del triángulo rectángulo ligeramente más pequeño que el de la base más alejada del eje de la rueda, debido a que ambos triángulos tienen la misma altura, pero la base del triángulo de la cara del prisma más cercana al eje de la rueda es más pequeña. Así pues, los prismas de las coronas (51 ,33), los prismas de las coronas (33,32) y finalmente los prismas de las coronas (32,41 ) están orientados en sentidos opuestos para facilitar el acople y desacople de la corona (51 ) con la corona (33) y también de la corona (32) con la corona (41 ), tal y como se aprecia en la FIG.5. Con la constitución así descrita, el eje principal (2) está girando en un determinado sentido de giro, la rueda central (3) que gira en el mismo sentido de giro del eje principal (2), está acoplada con una de las ruedas delimitadoras (4,5) girando ambas ruedas (central y acoplada) en el mismo sentido. Cada vez que el eje principal (2) cambia de sentido de giro, provoca que la rueda central (3) y la rueda delimitadora con la que está acoplada (4,5) giren en sentidos opuestos forzando que ambas ruedas (central y acoplada) se desacoplen gracias a la forma descrita de los dientes. Al desacoplarse la rueda central (3), ésta se desplaza longitudinalmente sobre el eje (2) y se acopla con la otra rueda delimitadora (4,5) girando ambas en el mismo sentido de giro. The teeth (32a, 33a, 41 a, 51 a) of the crowns (32,33,41, 51) respectively are triangular prisms with a section in the form of a right triangle. These prisms are located on the surface of the respective wheels (3,4,5) supported on at least one of the legs of the right triangle of the section. To achieve a perfect coupling, it is necessary that one of the bases, closest to the wheel axle, has a leg of the right triangle slightly smaller than that of the base farthest from the wheel axle, because both triangles they have the same height, but the base of the triangle on the face of the prism closest to the wheel axis is smaller. Thus, the prisms of the crowns (51, 33), the prisms of the crowns (33,32) and finally the prisms of the crowns (32,41) are oriented in opposite directions to facilitate the coupling and decoupling of the crown (51) with the crown (33) and also the crown (32) with the crown (41), as shown in FIG. 5. With the constitution thus described, the main shaft (2) is rotating in a certain direction of rotation, the central wheel (3) that rotates in the same direction of rotation of the main shaft (2), is coupled with one of the bounding wheels (4,5) turning both wheels (central and coupled) in the same direction. Each time the main axle (2) changes its direction of rotation, it causes the central wheel (3) and the bounding wheel with which it is coupled (4,5) to rotate in opposite directions, forcing both wheels (central and coupled) undock thanks to the described shape of the teeth. When the central wheel (3) is disengaged, it travels longitudinally on the axle (2) and engages with the other bounding wheel (4,5) by turning both in the same direction of rotation.
La orientación de los dientes que conforman las coronas en cada una de las ruedas (3,4,5) es tal que, al girar la rueda central (3) en sentido horario, la corona dentada (32) de la rueda central (3) y la corona dentada (41 ) de la rueda delimitadora (4) se desacoplan, haciendo que la rueda central (3) se desplace horizontalmente sobre el eje (2) y provocando que la corona dentada (33) de la rueda central (3) se acople con la corona dentada (51 ) de la rueda delimitadora (5) y por tanto que las ruedas (3) y (5) giren en sentido horario. En la FIG.6 se representa visualmente este caso dibujando en planta el movimiento de las ruedas (3, 4 y 5). The orientation of the teeth that make up the crowns on each of the wheels (3,4,5) is such that, when turning the central wheel (3) clockwise, the toothed crown (32) of the central wheel (3 ) and the toothed crown (41) of the bounding wheel (4) are disengaged, causing the central wheel (3) to move horizontally on the axle (2) and causing the toothed crown (33) of the central wheel (3) ) fit with the gear ring (51) of the bounding wheel (5) and therefore the wheels (3) and (5) turn clockwise. In FIG. 6 this case is visually depicted by drawing the movement of the wheels (3, 4 and 5).
Del mismo modo, si la rueda central (3) gira en sentido anti-horario, la corona dentada (33) de la rueda central (3) y la corona (51 ) de la rueda delimitadora (5) se desacoplan, haciendo que la rueda central (3) se desplace horizontalmente sobre el eje principal (2) provocando que la corona dentada (32) de la rueda central (3) se acople con la corona dentada (41 ) de la rueda delimitadora (4) y por tanto que las ruedas (3) y (4) giren en sentido anti-horario. Similarly, if the central wheel (3) turns counterclockwise, the toothed crown (33) of the central wheel (3) and the crown (51) of the bounding wheel (5) are disengaged, causing the central wheel (3) moves horizontally on the main axle (2) causing the toothed crown (32) of the central wheel (3) to engage with the toothed crown (41) of the bounding wheel (4) and therefore The wheels (3) and (4) turn counterclockwise.
En la FIG.7 se muestra la orientación de las coronas dentadas interiores de las ruedas (3,4,5). Estos elementos están montados sobre el eje principal (2) de forma que las ruedas delimitadoras (4,5) giran libremente sobre el mismo, no estando fijadas por tanto al citado eje (2). La primera y segunda rueda dentada auxiliar (6,12) se corresponden con un cuerpo macizo sujeto a sus respectivos ejes (7,13). La FIG.8 muestra una representación de las mismas, mientras que la FIG.9 muestra la tercera y cuarta rueda dentada auxiliar (9,1 1 ) y sus respectivos ejes (8,10). The orientation of the inner toothed crowns of the wheels (3,4,5) is shown in FIG. 7. These elements are mounted on the main axle (2) so that the bounding wheels (4,5) rotate freely on it, not therefore being fixed to said axle (2). The first and second auxiliary sprockets (6.12) correspond to a solid body attached to their respective axles (7.13). FIG. 8 shows a representation thereof, while FIG. 9 shows the third and fourth auxiliary sprockets (9.1 1) and their respective axles (8.10).
En la FIG.10 se muestra el sentido de giro de todas las piezas cuando el dispositivo se desplaza horizontalmente de izquierda a derecha. En esta situación, la primera rueda (1 ), el eje (2) y la rueda central (3) giran en sentido horario. No obstante, la rueda central (3) se desplaza horizontalmente hacia la segunda rueda delimitadora (5) y queda acoplada a la misma transmitiendo el sentido de giro horario. Consecuentemente, la primera rueda dentada auxiliar (6) y su eje (7) giran en sentido anti-horario, la tercera rueda dentada auxiliar (9) gira en sentido horario, la primera rueda delimitadora (4) en sentido anti-horario sobre el eje (2) que gira en sentido horario, mientras que la rueda auxiliar (12) y su eje (13) giran en sentido horario, mientras que, finalmente la rueda auxiliar (1 1 ) gira en sentido anti-horario, la cual está acoplada con la rueda delimitadora (5) que gira en sentido horario. FIG. 10 shows the direction of rotation of all parts when the device moves horizontally from left to right. In this situation, the first wheel (1), the axle (2) and the center wheel (3) turn clockwise. However, the central wheel (3) moves horizontally towards the second bounding wheel (5) and is coupled thereto transmitting the clockwise direction of rotation. Consequently, the first auxiliary cogwheel (6) and its axle (7) rotate counterclockwise, the third auxiliary cogwheel (9) rotates clockwise, the first delimiter wheel (4) counterclockwise on the axle (2) that rotates clockwise, while the auxiliary wheel (12) and its axle (13) rotate clockwise, while finally the auxiliary wheel (1 1) rotates counterclockwise, which is coupled with the bounding wheel (5) that rotates clockwise.
Al cambiar de sentido de uso, pasando a ser desplazado de derecha a izquierda (FIG.1 1 ), la primera rueda (1 ), el eje (2) y la rueda central (3) giran en sentido anti-horario. La rueda central (3) se desplaza horizontalmente hacia la pieza (4) y queda acoplada a la misma transmitiendo el sentido de giro anti-horario. Consecuentemente, la rueda dentada auxiliar (12) y su eje (13) giran en sentido horario, la rueda dentada auxiliar (1 1 ) gira en sentido anti- horario, la segunda rueda delimitadora (5) en sentido horario sobre el eje (2) que gira en sentido anti-horario, mientras que la rueda auxiliar (6) y su eje (7) giran en sentido antihorario, mientras que, finalmente la rueda auxiliar (9) gira en sentido horario, la cual está acoplada con la rueda delimitadora (4) que gira en sentido anti-horario. When changing the direction of use, moving from right to left (FIG. 1), the First wheel (1), axle (2) and center wheel (3) turn counterclockwise. The central wheel (3) moves horizontally towards the part (4) and is coupled to it, transmitting the anti-clockwise direction of rotation. Consequently, the auxiliary sprocket (12) and its axle (13) rotate clockwise, the auxiliary sprocket (1 1) rotates counterclockwise, the second bounding wheel (5) clockwise on the axle (2 ) which rotates counterclockwise, while the auxiliary wheel (6) and its axle (7) rotate counterclockwise, while finally the auxiliary wheel (9) rotates clockwise, which is coupled with the wheel delimiter (4) that rotates counterclockwise.
