APARATO AUTOMÁTICO DE AUTO-DESINFECCIÓN DE OBJETOSAUTOMATIC DEVICE FOR SELF-DISINFECTION OF OBJECTS
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un aparato automático de auto-desinfección de objetos que aporta, a la función a que se destina, ventajas y características, que se describen en detalle más adelante.The invention, as expressed in the title of this specification, refers to an automatic device for self-disinfection of objects that provides, to the function for which it is intended, advantages and characteristics, which are described in detail later.
El objeto de la presente invención recae en un aparato de funcionamiento automático que constituye un sistema de auto-desinfección de objetos mediante un túnel o módulo cerrado de aplicación de luz ultravioleta tipo C con transporte automático de los objetos a desinfectar que presenta la particularidad de consistir en un sistema de transporte específico para posibilitar el paso del objeto por el interior de la zona de desinfección de manera autónoma, es decir, sin necesidad de manipularlo, y permitiendo la incidencia de la luz UVC en toda la superficie inferior del objeto, asegurando su completa desinfección frente a agentes patógenos en toda la superficie del objeto, ya que dicho sistema de transporte permite la incidencia de irradiancia UVC sin generación de sombras así como la desinfección de un elevado número de objetos en rotación continua.The object of the present invention lies in an automatic operating apparatus that constitutes a self-disinfection system for objects through a tunnel or closed module for the application of type C ultraviolet light with automatic transport of the objects to be disinfected, which has the particularity of consisting in a specific transport system to enable the object to pass through the interior of the disinfection area autonomously, that is, without the need to manipulate it, and allowing the incidence of UVC light on the entire lower surface of the object, ensuring its Complete disinfection against pathogenic agents on the entire surface of the object, since said transport system allows the incidence of UVC irradiance without generating shadows, as well as the disinfection of a large number of objects in continuous rotation.
CAMPO DE APLICACIÓN DE LA INVENCIÓNFIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de equipos de desinfección, abarcando concretamente los que utilizan luz ultravioleta. The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of disinfection equipment, specifically covering those that use ultraviolet light.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Los aparatos y dispositivos existentes actualmente para la desinfección de objetos mediante aplicación de luz ultravioleta se basan, generalmente, en la aplicación de dicha luz ultravioleta en armarios cerrados o cabinas estancas, con la consiguiente necesidad de manipulación manual de los objetos a desinfectar. Por tanto, no evitan el problema que la invención actual aborda: proceso de desinfección sin necesidad de manipulación humana del objeto a desinfectar y una rápida rotación.Currently existing apparatus and devices for the disinfection of objects by applying ultraviolet light are generally based on the application of said ultraviolet light in closed cabinets or airtight cabins, with the consequent need for manual handling of the objects to be disinfected. Therefore, they do not avoid the problem that the current invention addresses: a disinfection process without the need for human manipulation of the object to be disinfected and a rapid rotation.
En el caso específico de las bandejas utilizadas en controles de aeropuertos, no existen registros de invenciones para un uso similar. Existen dispositivos que incorporan la luz ultravioleta, pero se enfocan a otras aplicaciones completamente diferentes y, por tanto, su disposición, forma y uso son radicalmente distintos. Es el caso de los robots que incorporan luz UV para la desinfección de estancias.In the specific case of the trays used in airport controls, there are no records of inventions for a similar use. There are devices that incorporate ultraviolet light, but they focus on completely different applications and, therefore, their layout, shape and use are radically different. This is the case of robots that incorporate UV light for the disinfection of rooms.
Además, la gran diferencia respecto a los desarrollos conocidos radica en la concepción estática del aparato, que requiere manipulación externa: personas que introduzcan y extraigan los objetos sometidos al proceso de desinfección. Las invenciones se basan en la aplicación de luz ultravioleta en armarios cerrados o cabinas estancas, con la consiguiente necesidad de manipulación manual, problemática que aborda y elimina la presente invención.In addition, the great difference with respect to known developments lies in the static conception of the device, which requires external manipulation: people who insert and extract the objects subjected to the disinfection process. The inventions are based on the application of ultraviolet light in closed cabinets or airtight cabins, with the consequent need for manual handling, a problem that the present invention addresses and eliminates.
Por otra parte, si bien en algunos casos en los que se usa la luz UV para la desinfección del objeto en túneles se incorporan sistemas de transporte, no se garantiza la completa desinfección del objeto, puesto carecen de un sistema que posibilite la aplicación de luz UV sobre toda la superficie del objeto, lo que sí hace posible la presente invención.On the other hand, although in some cases in which UV light is used to disinfect the object in tunnels, transport systems are incorporated, the complete disinfection of the object is not guaranteed, since they lack a system that allows the application of light. UV over the entire surface of the object, which does make the present invention possible.
Los documentos que se mencionan a continuación son un ejemplo de algunos de los sistemas conocidos más cercanos al objeto de la invención: - Patente US2020078483A1, referida a un sistema de Incorporación de luz ultravioleta en un dispositivo de desinfección de calzado.The documents mentioned below are an example of some of the known systems closest to the object of the invention: - Patent US2020078483A1, referring to a system for the incorporation of ultraviolet light in a shoe disinfection device.
- Patente KR102101243B1, referida a un sistema de Aplicación de luz ultravioleta a la desinfección de prendas de ropa.- Patent KR102101243B1, referring to a system for the application of ultraviolet light to the disinfection of clothing.
- Patente AU2020202565A1, referida a un Esterilizador para dispositivos móviles.- Patent AU2020202565A1, referring to a Sterilizer for mobile devices.
- Patente US2020147248A1, referida a una Unidad de desinfección para objetos de volumen.- Patent US2020147248A1, referring to a disinfection unit for large objects.
- Patente KR101245373B1, referida a un Sistema de desinfección para productos cárnicos. En este caso, si bien incluye un sistema de transporte, se trata de un sistema de transporte muy distinto. Además, la aplicación UV está ideada para desinfectar sin estropear los productos cárnicos y no cuenta con una disposición que posibilite la aplicación de la luz sobre toda la superficie para garantizar una desinfección profunda de patógenos.- Patent KR101245373B1, referring to a disinfection system for meat products. In this case, although it includes a transport system, it is a very different transport system. In addition, the UV application is designed to disinfect meat products without damaging them and does not have a provision that allows the application of light on the entire surface to guarantee deep disinfection of pathogens.
- Patente CN210044525U, referida a un Sistema de desinfección de objetos pequeños colocado en bandejas fijas. En este caso, aunque también incluye un sistema de transporte, se trata de un sistema pensado para la desinfección de objetos pequeños colocados sobre bandejas, pero no para la desinfección de las propias bandejas u otros objetos independientes.- Patent CN210044525U, referring to a disinfection system for small objects placed on fixed trays. In this case, although it also includes a transport system, it is a system designed for the disinfection of small objects placed on trays, but not for the disinfection of the trays themselves or other independent objects.
En consecuencia, y como referencia al estado actual de la técnica, no parece que ninguna de las patentes señaladas, tomadas de manera independiente o en combinación, describa un aparato automático de autodesinfección de objetos como el de la presente invención o que presente unas características técnicas iguales o semejantes a las que se reivindican de dicho aparato. Consequently, and as a reference to the current state of the art, it does not appear that any of the patents indicated, taken independently or in combination, describe an automatic device for self-disinfection of objects such as that of the present invention or that it has technical characteristics equal or similar to those claimed for said apparatus.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
El aparato automático de auto-desinfección de objetos que la invención propone se configura como la solución idónea al objetivo anteriormente señalado, estando los detalles caracterizadores que lo hacen posible y que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción.The automatic device for self-disinfection of objects that the invention proposes is configured as the ideal solution for the aforementioned objective, the characterizing details that make it possible and that conveniently distinguish it being collected in the final claims that accompany this description.
Concretamente, lo que la invención propone, como se ha apuntado anteriormente, es un aparato de funcionamiento automático que constituye un sistema de auto-desinfección de objetos que, básicamente, comprende un módulo de aplicación de luz ultravioleta tipo C que incluye un sistema de transporte automático de los objetos a desinfectar con la ventaja de que dicho sistema de transporte es un sistema de transporte específico para posibilitar el paso del objeto por el interior de la zona de desinfección de manera autónoma, es decir, sin necesidad de que se tenga que manipular los objetos al entrar o salir, y con la ventaja de permitir la incidencia de la mencionada luz UVC en toda la superficie inferior del objeto, asegurando su completa desinfección frente a agentes patógenos en toda la superficie del objeto, ya que cuenta con lámparas tanto en la parte superior como en la parte inferior del módulo y dicho sistema de transporte permite el paso de la luz a su través, lo que, a su vez, permite la incidencia de irradiancia UVC sobre la totalidad de la superficie de los objetos sin generación de sombras así como la desinfección de un elevado número de objetos en rotación continua.Specifically, what the invention proposes, as noted above, is an automatic operating device that constitutes a self-disinfection system for objects that basically comprises a type C ultraviolet light application module that includes a transport system of the objects to be disinfected with the advantage that said transport system is a specific transport system to enable the passage of the object inside the disinfection area autonomously, that is, without the need to manipulate objects when entering or leaving, and with the advantage of allowing the incidence of the mentioned UVC light on the entire lower surface of the object, ensuring its complete disinfection against pathogens on the entire surface of the object, since it has lamps both on the upper part as in the lower part of the module and said transport system allows the passage of light through it, which, in turn, allows te the incidence of UVC irradiance on the entire surface of the objects without generating shadows as well as the disinfection of a large number of objects in continuous rotation.
Además, el módulo de aplicación de luz ultravioleta está configurado como un túnel cerrado como para que la luz no sea visible, puesto que la luz UVC puede ser dañina a la piel y ojos si está en contacto directo, y que, al mismo tiempo, evita la pérdida de longitud de onda. Por ello, la disposición de la luz ultravioleta en el aparato de la invención permite su uso en espacios en los que haya personas de forma inocua.In addition, the ultraviolet light application module is configured as a closed tunnel so that the light is not visible, since UVC light can be harmful to the skin and eyes if it is in direct contact, and that, at the same time, prevents loss of wavelength. For this reason, the provision of the ultraviolet light in the apparatus of the invention allows its use in spaces in which there are people in an innocuous way.
El aparato contempla, al menos, dos posibles configuraciones, en función de su posible aplicación y, por tanto, del tipo de objetos a desinfectar.The device contemplates at least two possible configurations, depending on its possible application and, therefore, on the type of objects to be disinfected.
Así, en una forma de realización, diseñada para la desinfección de bandejas u objetos de tamaño medio, el aparato comprende, esencialmente:Thus, in one embodiment, designed for the disinfection of trays or medium-sized objects, the device essentially comprises:
- Sendas bandas de transporte estándar de rodillos para entrada y salida del objeto u objetos a desinfectar hacia y desde el módulo de desinfección. - Y, un módulo de desinfección que a su vez, al menos, comprende:- Two standard roller transport belts for the entry and exit of the object or objects to be disinfected to and from the disinfection module. - And, a disinfection module which, in turn, at least includes:
- Un conjunto de lámparas UVC superior.- A set of superior UVC lamps.
- Un conjunto de lámparas UVC inferior.- A set of lower UVC lamps.
- Un sistema para el transporte autónomo del objeto a su paso por el módulo que permite la desinfección de toda la superficie inferior del mismo.- A system for the autonomous transport of the object as it passes through the module that allows the disinfection of its entire lower surface.
Preferentemente, la luz UV-C de las lámparas es el tipo de radiación ultravioleta que se sitúa en un intervalo de longitudes de onda tal, que tiene efecto germicida y su colocación superior e inferiormente al sistema de transporte autónomo garantiza la eficiencia máxima en el proceso de desinfección.Preferably, the UV-C light from the lamps is the type of ultraviolet radiation that is located in a range of wavelengths such that it has a germicidal effect and its placement above and below the autonomous transport system guarantees maximum efficiency in the process. of disinfection.
La cantidad de inactivación de patógenos es directamente proporcional a la dosis de radiación UV, definiéndose como el producto de intensidad (W/m2) y tiempo de exposición (s). La intensidad a su vez depende de la distancia del foco emisor de luz UV-C al objeto y disminuye al aumentar esta. Para ser efectiva requiere la exposición directa sobre la superficie a desinfectar, por lo que las zonas de sombras a las que no llega directamente la exposición de luz UV-C permanecen contaminadas, constituyendo un foco de infección. Para evitar esta problemática, se ha desarrollado un sistema de transporte que permite el traslado del objeto sobre una fuente de emisores o conjunto de lámparas luz UV-C superior e inferior, incidiendo esta en toda la superficie del objeto, sin producir sombras.The amount of pathogen inactivation is directly proportional to the dose of UV radiation, defined as the product of intensity (W/m2) and exposure time (s). The intensity in turn depends on the distance from the source of UV-C light to the object and decreases with increasing distance. To be effective, it requires direct exposure to the surface to be disinfected, so the shadow areas that it does not reach direct exposure to UV-C light remain contaminated, constituting a focus of infection. To avoid this problem, a transport system has been developed that allows the object to be moved over a source of emitters or a set of upper and lower UV-C light lamps, affecting the entire surface of the object, without producing shadows.
Por su parte, el sistema de transporte preferentemente comprende:For its part, the transport system preferably comprises:
- Una pluralidad de ejes transmisores de movimiento, dispuestos en paralelo y transversalmente al sentido de desplazamiento.- A plurality of movement transmitting axes, arranged parallel and transversal to the direction of movement.
- Una pluralidad de rodamientos auto-alineables con tornillos prisioneros en el anillo interior para soporte de apoyo de los ejes transmisores en ambos extremos de cada uno de ellos.- A plurality of self-aligning bearings with grub screws in the inner ring to support the drive shafts at both ends of each of them.
- Una estructura soporte a base de perfilería metálica en que se incorpora y sustenta el resto de elementos.- A support structure based on metal profiles in which the rest of the elements are incorporated and supported.
- Una pluralidad de poleas transportadoras del objeto fijadas, al menos por pares, en todos los ejes solidariamente a los mismos de manera que giran con ellos.- A plurality of object-conveying pulleys fixed, at least in pairs, to all the axes integrally with them so that they rotate with them.
- Y una pluralidad de poleas transmisoras incorporadas una en cada eje en uno de sus extremos para proporcionar movimiento de giro a los mismos, a través de un sistema de transmisión.- And a plurality of transmission pulleys incorporated, one on each axis at one of its ends to provide rotational movement to them, through a transmission system.
Con ello, las poleas transportadoras, por su forma circular, tocan la superficie del objeto en un punto que va cambiando al girar el eje transmisor durante el avance del objeto de manera que la zona de contacto es mínima y cambiante. De esta forma se asegura una distribución homogénea de la luz UVC tanto superior como inferiormente y, por tanto, sin sombras permanentes.With this, the conveyor pulleys, due to their circular shape, touch the surface of the object at a point that changes when the transmission shaft rotates during the advance of the object, so that the contact area is minimal and changes. In this way, a homogeneous distribution of UVC light is ensured both above and below and, therefore, without permanent shadows.
Las poleas transmisoras van instaladas en uno de los extremos de los ejes, fuera de la zona de paso del objeto. El movimiento de estos ejes, que permite el avance del objeto, se produce mediante transmisión por correas desde los rodillos motrices de los transportadores estándar de entrada y salida a una de las poleas de transmisión del primer eje, y luego este movimiento se traslada también por correas, pero esta vez entre las poleas transmisoras diseñadas.The transmission pulleys are installed at one of the ends of the shafts, outside the passage area of the object. The movement of these axes, which allows the object to move forward, it is produced by belt transmission from the drive rollers of the standard input and output conveyors to one of the transmission pulleys of the first axis, and then this movement is also transferred by belts, but this time between the engineered drive pulleys.
El aparato es adaptable a distintos formatos y dimensiones.The device is adaptable to different formats and dimensions.
Opcionalmente, para evitar la caída de objetos pequeños en el espacio entre ejes del sistema de transporte anteriormente descrito, se ha diseñado una segunda variante de configuración que comprende la incorporación de una banda de malla fina que igualmente permite el paso de la luz UVC sirviendo como elemento de transporte del objeto.Optionally, to prevent small objects from falling into the space between the axles of the previously described transport system, a second configuration variant has been designed that includes the incorporation of a fine mesh band that also allows the passage of UVC light, serving as object transport element.
En este caso, el sistema de transporte comprende:In this case, the transport system comprises:
- Una banda transportadora de malla, que permite el paso de luz UVC sin generar sombras.- A mesh conveyor belt, which allows the passage of UVC light without generating shadows.
- Y una pluralidad de rodillos de transmisión del movimiento a la banda.- And a plurality of rollers for transmission of movement to the band.
Preferentemente, dicha banda de malla es una malla fina de material de alta reflectividad que permite el paso de luz UVC. Además, en dicha realización la ubicación de las lámparas de luz inferiores se efectúa en el espacio interior de la banda, a una distancia mínima del objeto a desinfectar, y por tanto aumentando la eficiencia y efectividad del proceso. La primera configuración está especialmente ideada para entornos de alta rotación de objetos comunes, en los que la desinfección juega un papel fundamental para evitar posibles contagios de enfermedades. La automatización de los sistemas de desinfección evita la necesidad de manipulación manual de los objetos, reduciendo en mayor medida el riesgo de contagio. Un ejemplo de ello es el caso de las bandejas utilizadas en los controles de seguridad de los aeropuertos, para las que es necesario garantizar la desinfección tras ser usada por un usuario y antes de ser usada por el siguiente y dotar al sistema de la velocidad necesaria para agilizar el sistema de control y evitar aglomeraciones.Preferably, said mesh band is a fine mesh of high reflectivity material that allows the passage of UVC light. In addition, in said embodiment, the location of the lower light lamps is carried out in the interior space of the band, at a minimum distance from the object to be disinfected, and therefore increasing the efficiency and effectiveness of the process. The first configuration is specially designed for environments with a high turnover of common objects, in which disinfection plays a fundamental role in avoiding possible contagion of diseases. The automation of disinfection systems avoids the need for manual handling of objects, further reducing the risk of contagion. An example of this is the case of the trays used in the airport security controls, for which it is necessary to guarantee disinfection after being used by one user and before being used by the next and provide the system with the necessary speed to speed up the control system and avoid crowds.
En esta situación, la automatización del proceso elimina el riesgo de contagio evitando la necesidad de manipulación manual para realizar la desinfección: la bandeja sigue un circuito automático, basado en un sistema automático de transporte hasta llegar al túnel de desinfección, del cual sale completamente libre de agentes patógenos. La no intervención manual reduce el riesgo de contaminación por errores en manipulación y evita distorsionar el control del tiempo de exposición de los objetos a la luz UVC. Para ello, la velocidad de avance del sistema de transporte de objetos en el interior del módulo estará convenientemente programada para que el tiempo de exposición a la luz a que se ven sometidos los objetos durante dicho avance sea el suficiente como para resultar efectiva la desinfección.In this situation, the automation of the process eliminates the risk of contagion, avoiding the need for manual handling to carry out the disinfection: the tray follows an automatic circuit, based on an automatic transport system until it reaches the disinfection tunnel, from which it leaves completely free of pathogens. The non-manual intervention reduces the risk of contamination due to handling errors and avoids distorting the control of the exposure time of objects to UVC light. To do this, the advance speed of the object transport system inside the module will be suitably programmed so that the time of exposure to light to which the objects are subjected during said advance is sufficient for the disinfection to be effective.
Por su parte, la variante de configuración destinada a objetos pequeños puede tener numerosas aplicaciones en entornos industriales.For its part, the configuration variant intended for small objects can have numerous applications in industrial environments.
