El sector de la técnica de esta invención es la industria de consumo en general, en la que sea necesario la limpieza de piezas cilíndricas de mayor base que altura en pequeñas series. Una aplicación muy concreta es la limpieza de quesos.The technical sector of this invention is the consumer industry in general, where the cleaning of cylindrical pieces of greater base than height in small series. A very specific application is cheese cleaning.

En las pequeñas industrias, tales como queserías artesanales, la limpieza de las piezas se realiza principalmente de forma manual, debido a que se hace difícil rentabilizar la inversión en una máquina.In small industries, such as cheese factories handcrafted, the cleaning of the pieces is mainly done by manually, because it becomes difficult to monetize the Investment in a machine.

Prior art

Para la limpieza de quesos se vienen empleando, para grandes series, líneas automáticas para la limpieza en continuo, tales como las descritas en las patentes nacionales P0495635, U8800810 o U0254811, o las patentes europeas DE2015375, o IT1243612.For cheese cleaning they are being used, for large series, automatic lines for cleaning in continuous, such as those described in national patents P0495635, U8800810 or U0254811, or European patents DE2015375, or IT1243612.

Para limpieza unitaria de grandes quesos existen máquinas, tales como las descritas en las patentes europeas CH690288 o DE4217950.For unit cleaning of large cheeses there are machines, such as those described in European patents CH690288 or DE4217950.

Para limpieza de pequeñas series pieza a pieza, existe una máquina concebida como un cajón rectángular donde hay 3 ejes, provistos de cepillos y accionados por dos motores, dispuestos dos de ellos de forma paralela y otro perpendicular a ellos. Existe un rodillo paralelo a éste último cepillo que sirve de apoyo a la pieza. Para la limpieza se coloca una pieza entre los dos cepillos paralelos, y el tercer cepillo hace rodar la pieza sobre el mismo punto, cepillando de esa forma los tres cepillos a la pieza.For cleaning small series piece by piece, there is a machine designed as a rectangular drawer where there are 3 shafts, equipped with brushes and driven by two motors, arranged two of them in parallel and another perpendicular to they. There is a roller parallel to the latter brush that serves of support to the piece. For cleaning a piece is placed between the two parallel brushes, and the third brush rolls the piece on the same point, brushing the three brushes in that way piece.

Las máquinas existentes en la actualidad, o bien están concebidas para una alta producción y no son rentables económicamente en esas pequeñas queserías, o tienen un funcionamiento unitario y de configuración compleja.The machines currently in existence, or They are designed for high production and are not profitable economically in those small cheese factories, or have a unit operation and complex configuration.

La presente invención tiene por objeto la construcción de una máquina de limpieza para pequeñas series con una configuración simplificada y mínima ocupación de espacio.The present invention aims at the construction of a cleaning machine for small series with a simplified configuration and minimal space occupation.

Para ello se emplea el principio del movimiento planetario, haciendo que, por efecto del giro, con eje vertical, de un órgano de limpieza central colocado en el centro de un tambor de limpieza, las piezas a limpiar se desplacen alrededor de él por la periferia del tambor animadas de movimiento simultáneo de traslación y giro. En el tambor de limpieza estarán flanqueadas por sus caras superior e inferior por otros órganos de limpieza a modo de base y tapa, respecto de las cuáles tendrán un movimiento relativo que producirá la limpieza de las piezas por dichas caras.For this the movement principle is used planetary, causing, by rotation, with vertical axis, of a central cleaning device placed in the center of a drum of cleaning, the parts to be cleaned move around it through the Animated drum periphery of simultaneous translation movement and turn. In the cleaning drum they will be flanked by their faces upper and lower by other cleaning organs as a base and cover, with respect to which they will have a relative movement that will produce the cleaning of the pieces by said faces.

De esta forma es posible fabricar una máquina de limpieza para pequeñas series mucho más sencilla que las actuales, puesto que cuenta con una única pieza móvil y escaso nº de piezas, con lo que el coste de la máquina se reduce considerablemente, al tiempo que es posible limpiar varias piezas en cada ciclo de trabajo.In this way it is possible to manufacture a machine cleaning for small series much simpler than the current ones, since it has a single moving part and a small number of pieces, with which the cost of the machine is reduced considerably, by time it is possible to clean several pieces in each cycle of job.

Se aportan dos dibujos para mejor comprensión de la explicación posterior, en los que se muestra la máquina en perspectiva y en sección.Two drawings are provided for a better understanding of the subsequent explanation, in which the machine is shown in perspective and section.

Detailed description

La máquina propuesta consiste en un tambor cilíndrico (1) en cuya base se encuentra un cepillo plano (4) en forma anular.The proposed machine consists of a drum cylindrical (1) at whose base is a flat brush (4) in ring shape

Por la parte inferior de dicho tambor (1) se introduce un eje (3) accionado por un motorreductor (2) de la potencia y nº de revoluciones convenientes en función del nº y diámetro de elementos a limpiar así como del diámetro del tambor. Ese eje arrastra un cepillo cilíndrico (5), de dimensiones adecuadas, que al girar provocará simultáneamente el giro y arrastre de las piezas a limpiar. Una vez colocadas las piezas a limpiar en la periferia del tambor, se coloca como tapa otro cepillo (6), el cual se cierra con unos pestillos (7) diseñados para presionar la tapa y evitar el giro de ésta.From the bottom of said drum (1) is introduces a shaft (3) driven by a gearmotor (2) of the power and number of revolutions convenient depending on the number and diameter of elements to be cleaned as well as the diameter of the drum. This axis drags a cylindrical brush (5), of dimensions suitable, which when turning will simultaneously cause the rotation and drag of the parts to be cleaned. Once the pieces have been placed clean on the periphery of the drum, another brush is placed as a cover (6), which closes with latches (7) designed to press the lid and avoid turning it.

La máquina puede realizar la limpieza en seco o con empleo de agua u otro líquido conveniente, al estar dotada de retén de cierre (8) en su eje.
