Description

SISTEMAS DE SEGURIDAD PARA MOLINO DESFIBRADOR  SAFETY SYSTEMS FOR DEFIBRATOR MILL
DESCRIPCIÓN DESCRIPTION
Campo técnico de la invención Technical Field of the Invention
La presente invención corresponde al campo técnico de los molinos desfibradores, y en concreto a unos sistemas de seguridad para los mismos, donde dichos molinos están destinados a la trituración y desfibrado de materias primas. The present invention corresponds to the technical field of defibrator mills, and in particular to safety systems for them, where said mills are intended for crushing and defibration of raw materials.
Antecedentes de la Invención Background of the Invention
En la actualidad, los sistemas de trituración y desfibrado de materias primas, tales como las piñas de agave, cuentan con varios molinos. Un primer molino procesa la materia prima entera y la trocea hasta un determinado tamaño. Un segundo molino recoge el producto procesado por el primer molino, y lo vuelve a trocear hasta conseguir un tamaño más reducido. Posteriormente, un tercer molino se encarga de recoger el producto del segundo molino y desfibrarlo de manera que éste quede en condiciones para poder extraer sus azucares. At present, the crushing and defibration systems of raw materials, such as agave pineapples, have several mills. A first mill processes the entire raw material and cuts it up to a certain size. A second mill picks up the product processed by the first mill, and cuts it back to a smaller size. Subsequently, a third mill is responsible for collecting the product of the second mill and defibrating it so that it is able to extract its sugars.
Esta sucesión de molinos entraña una serie de inconvenientes, como son el coste de mantenimiento, de personal, y de piezas de las propias máquinas. This succession of mills entails a series of drawbacks, such as the cost of maintenance, personnel, and parts of the machines themselves.
Así mismo, estos molinos requieren grandes espacios para su instalación. Also, these mills require large spaces for installation.
Para solucionar estos inconvenientes, el solicitante ha logrado definir un nuevo molino desfibrador más económico y compacto, capaz de trocear y desfibrar las materias primas eficientemente. To solve these problems, the applicant has managed to define a new, more economical and compact defibrator mill, capable of cutting and defibrating raw materials efficiently.
Este molino presenta una tolva para la entrada de productos y una carcasa en cuyo interior presenta un primer y segundo disco conectados a un motor de rotación. This mill has a hopper for the entry of products and a housing inside which has a first and second disc connected to a rotation motor.
Al entrar la materia prima en el equipo, se encuentra con al menos una cuchilla anexada al primer disco y una cavidad de paso del material cortado hacia el espacio comprendido entre ambos discos. Las cuchillas giran con todo el sistema y van troceando el material hasta que las rebanadas tienen el tamaño determinado fijado previamente y pasan al otro lado del primer disco mediante las aberturas practicadas en el mismo. Una vez que el producto está entre los dos discos, unas cuchillas perimetrales siguen cortando el producto mientras unas cadenas se encargan de realizar el desfibrado del mismo. When the raw material enters the equipment, it is found with at least one blade attached to the first disk and a cavity of the cut material towards the space between both discs. The blades rotate with the entire system and chop the material until the slices have the predetermined size determined previously and pass to the other side of the first disc through the openings made in it. Once the product is between the two discs, perimeter blades continue to cut the product while chains are responsible for the defibration of the same.
Este nuevo molino desfibrador simplifica y sustituye al tren de molinos que habitualmente se han utilizado en la industria para estos trabajos de trituración y desfibrado, lo que conlleva un importante beneficio económico por tener que instalar únicamente un equipo en lugar del tren de equipos que se viene empleando en la industria, con lo que se reducen las necesidades de supervisión, el personal necesario, la inversión, los costes de mantenimiento, etc. This new shredder mill simplifies and replaces the train of mills that have usually been used in the industry for these crushing and shredding works, which entails an important economic benefit by having to install only one equipment instead of the equipment train that is coming employing in the industry, which reduces supervision needs, necessary personnel, investment, maintenance costs, etc.
Pero a su vez, es un molino que presenta dos discos cuyo movimiento ocasiona que el producto a desfibrar salga despedido por la fuerza centrífuga que genera el movimiento de rotación de los discos, y estos discos a su vez presentan cuchillas y cadenas que giran con los mismos. La existencia de todos estos elementos hace necesaria la instalación de una serie de elementos de seguridad que consigan una adecuada, correcta y segura operación y mantenimiento del equipo. But at the same time, it is a mill that has two discs whose movement causes the product to be defibrated to be fired by the centrifugal force generated by the rotational movement of the discs, and these discs in turn have blades and chains that rotate with the same. The existence of all these elements makes it necessary to install a series of security elements that achieve an adequate, correct and safe operation and maintenance of the equipment.

Descripción detallada de un modo de realización preferente de la invención Detailed description of a preferred embodiment of the invention
A la vista de las figuras aportadas, puede observarse cómo en un modo de realización preferente de la invención, los sistemas de seguridad para molino (1) desfibrador que aquí se proponen se refieren a molinos destinados a la trituración y desfibrado de materias primas. Estos molinos (1), como puede observarse en las Figuras 1 , 3.1 y 3.2, comprenden una tolva (2) para la entrada de productos, un primer y segundo disco (5.1 , 5.2) conectados a un motor de rotación, donde dicho primer disco (5.1) presenta al menos una cuchilla (6) y una abertura (7) hacia el espacio comprendido entre dichos primer y segundo disco (5.1 , 5.2), donde discurren unas cadenas (8) para desfibrar el producto. In view of the figures provided, it can be seen that in a preferred embodiment of the invention, the safety systems for mill (1) defibrator proposed herein refer to mills intended for crushing and defibrating raw materials. These mills (1), as can be seen in Figures 1, 3.1 and 3.2, comprise a hopper (2) for the entry of products, a first and second disk (5.1, 5.2) connected to a rotation motor, where said first disc (5.1) has at least one blade (6) and an opening (7) towards the space between said first and second disc (5.1, 5.2), where chains (8) run to defibrate the product.
Como se muestra en las Figuras 1 y 2, los sistemas de seguridad comprenden una carcasa (3) protectora del primer y segundo discos (5.1 , 5.2) así como de la al menos una cuchilla (6) de los mismos, un brazo hidráulico (4) conectado a la carcasa (3), un sensor de movimiento y unos medios de fijación de los discos. As shown in Figures 1 and 2, the safety systems comprise a protective housing (3) of the first and second discs (5.1, 5.2) as well as of the at least one blade (6) thereof, a hydraulic arm ( 4) connected to the housing (3), a motion sensor and means for fixing the discs.
La carcasa (3) protectora como se muestra en la Figura 1 , presenta forma cilindrica con dos bases circulares aptas para cubrir uno de los discos respectivamente y una superficie curva entre ambas. The protective housing (3) as shown in Figure 1, has a cylindrical shape with two circular bases suitable for covering one of the discs respectively and a curved surface between them.
Esta carcasa (3) evita que los trozos de producto salgan despedidos debido a la fuerza centrífuga de rotación generada durante el proceso de desfibrado, de manera que quedan contenidos dentro del molino (1) y no presentan ningún peligro. De no existir esta carcasa (3), los trozos de producto serían lanzados debido a dicha fuerza centrífuga, en cualquier dirección, y podrían impactar contra personas u objetos. This housing (3) prevents the pieces of product from being fired due to the centrifugal rotational force generated during the defibration process, so that they remain contained within the mill (1) and do not present any danger. If this housing (3) does not exist, the product pieces would be thrown due to said centrifugal force, in any direction, and could impact on people or objects.
Además, en una zona superior de dicha superficie curva presenta una tapa (9) de abertura y cierre que permite el acceso a la parte interna del molino (1), necesario en las labores de mantenimiento, ya sea para sustitución de algún elemento de corte, o para cualquier operación de control y supervisión. In addition, in an upper area of said curved surface it has an opening and closing cover (9) that allows access to the internal part of the mill (1), necessary in maintenance work, either to replace a cutting element , or for any control and supervision operation.
Por otra parte, el brazo hidráulico (4) conectado a la carcasa (3) es apto para producir la elevación de dicha tapa (9) de abertura y cierre de la carcasa (3). El brazo hidráulico (4) actúa cuando es necesario acceder al interior del molino (1), y facilita la operación de apertura y cierre de la tapa (9). On the other hand, the hydraulic arm (4) connected to the housing (3) is capable of causing the lifting of said cover (9) for opening and closing the housing (3). The hydraulic arm (4) acts when it is necessary to access the inside of the mill (1), and facilitates the operation of opening and closing the lid (9).
El sensor de movimiento de los medios de seguridad es apto para impedir la abertura de dicha tapa (9) de abertura y cierre de la carcasa (3), cuando el motor de rotación está en funcionamiento. The motion sensor of the safety means is suitable to prevent opening of said cover (9) for opening and closing the housing (3), when the rotation motor is running.
En este modo de realización preferente de la invención, dicho sensor de movimiento está conectado al eje del motor de rotación de manera que, el sensor de movimiento detecta si el eje está en rotación y por lo tanto si los discos (5.1 , 5.2) y las cuchillas (6) están girando. De este modo, cuando se pretende acceder al interior del molino (1) para mantenimiento, por ejemplo para realizar un cambio de cuchillas, si el sensor detecta que el conjunto está girando, no permite la abertura de la tapa de la carcasa. In this preferred embodiment of the invention, said motion sensor is connected to the axis of the rotation motor so that, the motion sensor detects if the axis is in rotation and therefore if the disks (5.1, 5.2) and The blades (6) are rotating. Thus, when it is intended to access the inside of the mill (1) for maintenance, for example to make a change of blades, if the sensor detects that the assembly is rotating, it does not allow the opening of the housing cover.
De este modo, hasta que el eje no está completamente parado no es posible la abertura de la tapa (9) y el acceso al interior del equipo, evitando de este modo posibles daños personales. Thus, until the shaft is not completely stopped, it is not possible to open the cover (9) and access to the interior of the equipment, thus avoiding possible personal injury.
Por otra parte, los medios de fijación de los discos (5.1 , 5.2) son aptos para impedir el movimiento de rotación de los mismos cuando dicha tapa (9) de abertura y cierre está en posición abierta. On the other hand, the fixing means of the discs (5.1, 5.2) are suitable to prevent the movement of rotation thereof when said opening and closing cover (9) is in the open position.
En este modo de realización preferente de la invención estos medios de fijación (no representados en las Figuras) isiide los discos están formados por un pestillo de seguridad y una abertura apta para inmovilizar el motor de rotación cuando el pestillo está dispuesto de forma interior a dicha abertura.  In this preferred embodiment of the invention these fixing means (not shown in the Figures) isiide the discs are formed by a safety latch and an opening capable of immobilizing the rotation motor when the latch is arranged internally to said opening.
Tanto la carcasa (3) como el pestillo de seguridad, en este modo de realización preferente de la invención, están realizados en acero al carbono, mientras que el brazo hidráulico (4) está formado por un cilindro de acero inoxidable. Both the housing (3) and the safety latch, in this preferred embodiment of the invention, are made of carbon steel, while the hydraulic arm (4) is formed by a stainless steel cylinder.
La forma de realización descrita constituye únicamente un ejemplo de la presente invención, por tanto, los detalles, términos y frases específicos utilizados en la presente memoria no se han de considerar como limitativos, sino que han de entenderse únicamente como una base para las reivindicaciones y como una base representativa que proporcione una descripción comprensible así como la información suficiente al experto en la materia para aplicar la presente invención. Con los sistemas de seguridad para molino desfibrador que aquí se presentan se consiguen importantes mejoras respecto al estado de la técnica. The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are only to be understood as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention. With the safety systems for shredder mill presented here, significant improvements are achieved with respect to the state of the art.
Así pues, se dota al molino desfibrador de unos sistemas que lo hacen mucho más seguro, evitando daños personales y materiales y que aseguran que el funcionamiento y mantenimiento del equipo resulten adecuados, correctos y seguros. Thus, the shredder mill is provided with systems that make it much safer, avoiding personal and material damage and ensuring that the operation and maintenance of the equipment are adequate, correct and safe.
Por una parte la carcasa evita que el producto salga disparado con fuerza en cualquier dirección, por lo que se está evitando los posibles impactos y daños no deseados, tanto a personas como a objetos. Y además se asegura que no sea posible el acceso al interior del molino cuando éste está en rotación, por lo que se evitan daños a los operarios, asegurando que las labores de mantenimiento y reparación sean seguras y cómodas. On the one hand, the housing prevents the product from firing strongly in any direction, so that possible impacts and unwanted damage are being avoided, both to people and objects. And it also ensures that access to the interior of the mill is not possible when it is in rotation, so that damage to the operators is avoided, ensuring that maintenance and repair work is safe and comfortable.
Esto se consigue con tanto con el sensor de movimiento que evita la abertura de la tapa cuando el motor está girando, como con el pestillo de fijación, que evita que se inicie la rotación de los discos si dicha tapa está abierta, por lo que los operarios pueden trabajar con total tranquilidad, sabiendo que no van a encontrarse en ningún caso con la rotación del equipo cuando ellos tienen acceso al interior de mismo. This is achieved with both the motion sensor that prevents the opening of the lid when the engine is rotating, as with the locking latch, which prevents the rotation of the discs if said lid is open, so that Operators can work with total peace of mind, knowing that they will not be in any case with the rotation of the equipment when they have access to the interior of it.
Finalmente, el brazo hidráulico permite la abertura y cierre de la tapa de la carcasa, facilitando dicho trabajo a los operarios. Finally, the hydraulic arm allows the opening and closing of the housing cover, facilitating said work for the operators.
Es un sistema de seguridad muy eficaz, que consigue que sea un equipo sencillo de utilizar y seguro para los operarios. It is a very effective security system, which makes it a simple equipment to use and safe for operators.
